INTRODUCTION
Unless otherwise indicated, all references in this Annual Report on Form 20-F, or annual report, to the terms “Exscientia,” “Exscientia plc,” “the company,” “we,” “us” and “our” refer to Exscientia plc together with its subsidiaries.
This annual report includes trademarks, trade names and service marks, certain of which belong to us and others that are the property of other organisations. Solely for convenience, trademarks, trade names and service marks referred to in this annual report appear without the ®, ™ and SM symbols, but the absence of those symbols is not intended to indicate, in any way, that we will not assert our rights or that the applicable owner will not assert its rights to these trademarks, trade names and service marks to the fullest extent under applicable law. We do not intend our use or display of other parties’ trademarks, trade names or service marks to imply, and such use or display should not be construed to imply a relationship with, or endorsement or sponsorship of us by, these other parties.
Presentation of Financial Information
Our financial statements in this annual report were prepared in accordance with IFRS Accounting Standards issued by the International Accounting Standards Board (“IASB”). None of our financial statements were prepared in accordance with U.S. GAAP.
Our financial information is presented in pounds sterling. For the convenience of the reader, in this annual report, unless otherwise indicated, translations from pounds sterling into U.S. dollars were made at the rate of £1.00 to $1.27, which was the noon buying rate of the Federal Reserve Bank of New York on December 29, 2023. Such U.S. dollar amounts are not necessarily indicative of the amounts of U.S. dollars that could actually have been purchased upon exchange of pounds sterling at the dates indicated or any other date.
All references in this annual report to “$” mean U.S. dollars and all references to “£” and “GBP” mean pounds sterling.
We have made rounding adjustments to some of the figures included in this annual report. Accordingly, numerical figures shown as totals in some tables may not be an arithmetic aggregation of the figures that preceded them.
Industry and Market Data
This annual report contains estimates, projections and other information concerning our industry, our business and the markets for our products. Information that is based on estimates, forecasts, projections, market research or similar methodologies is inherently subject to uncertainties, and actual events or circumstances may differ materially from events and circumstances that are assumed in this information. Unless otherwise expressly stated, we obtained this industry, business, market and other data from our own internal estimates and research as well as from reports, research surveys, studies and similar data prepared by market research firms and other third parties, industry, medical and general publications, government data and similar sources. While we are responsible for the accuracy of such information and believe our internal company research as to such matters is reliable and the market definitions are appropriate, neither such research nor these definitions have been verified by any independent source.
In addition, assumptions and estimates of our and our industry’s future performance are necessarily subject to a high degree of uncertainty and risk due to a variety of factors, including those described in the section titled “Item 3.D – Key Information – Risk Factors.” These and other factors could cause our future performance to differ materially from our assumptions and estimates. See “Special Note Regarding Forward-looking Statements.”

In some cases, you can identify forward-looking statements by the words “may,” “might,” “will,” “could,” “would,” “should,” “expect,” “intend,” “plan,” “objective,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “continue” and “ongoing,” or the negative of these terms or other comparable terminology intended to identify statements about the future. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, levels of activity, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements. The forward-looking statements and opinions contained in this annual report are based upon information available to us as of the date of this annual report and, while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information.

You should carefully consider all of the information set forth in this annual report and in our other filings with the United States Securities and Exchange Commission, or the SEC, including the following risk factors which we face and which are faced by our industry. Our business, financial condition or results of operations could be materially adversely affected by any of these risks. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us may also adversely affect our business.
Summary Risk Factors
Our business is subject to a number of risks and uncertainties. If any of the following risks are realized, our business, financial condition and results of operations could be materially and adversely affected. You should carefully review and consider the full discussion of our risk factors in this section of our annual report. Set forth below is a summary list of the principal risk factors as of the date of the filing this annual report:
We have a history of significant operating losses, and we expect to incur losses over the next several years.
If we and our present and future collaborators are unable to successfully develop and commercialise drug products, our revenues may be insufficient for us to achieve or maintain profitability.
Our interim and annual results may fluctuate significantly, which could adversely impact the value of our ADSs.
We may need additional funding in the future which may not be available on terms acceptable to us, or at all. If we are unable to raise additional capital or to generate cash flows necessary to maintain or expand our operations, we may not be able to compete successfully, which would harm our business, operations, financial condition and prospects.
We are substantially dependent on our technology platform to identify promising molecules to accelerate drug discovery and development. Our platform technology may fail to discover and design molecules with therapeutic potential or may not result in the discovery and development of commercially viable products for us or our collaborators.
Unfavourable global economic and geopolitical conditions could adversely affect our business, financial condition or results of operations.
All of our drug candidates are in early-stage clinical development or in preclinical development. If we are unable to advance our drug candidates through clinical development, to obtain regulatory approval and ultimately to commercialise our drug candidates, or if we experience significant delays in doing so, our business will be materially harmed.
Clinical development involves a lengthy and expensive process with uncertain outcomes. If our preclinical studies and clinical trials are not sufficient to support regulatory approval of any of our drug candidates, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development of such drug candidate.
6

Table of Contents
Our research activities and clinical trials may fail to demonstrate adequately the safety and efficacy of GTAEXS617 or any other drug candidate, which would prevent or delay development, regulatory approval and commercialisation.
We may not be successful in our efforts to identify or discover drug candidates and may fail to capitalise on programmes, collaborations or drug candidates that may present a greater commercial opportunity or for which there is a greater likelihood of success.
We face substantial competition, which may result in others discovering, developing or commercialising products before or more successfully than we do.
We have invested, and expect to continue to invest, in research and development efforts that further enhance our technology platform. If the return on these investments is lower or develops more slowly than we expect, our revenue and results of operations may suffer.
Our drug discovery collaborators have significant discretion regarding the clinical development of the programmes subject to the collaboration. The failure of our collaborators to perform their obligations under our collaboration agreements could negatively impact our business. We may never realise the return on our investment of resources in our drug discovery collaborations.
We contract with third parties for the manufacture of our drug candidates for preclinical development and clinical testing, and expect to continue to do so for commercialisation. This reliance on third parties increases the risk that we will not have sufficient quantities of our drug candidates or products or such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialisation efforts.
We rely on third parties to conduct our clinical trials of GTAEXS617 and expect to rely on third parties to conduct future clinical trials, as well as investigator-sponsored clinical trials of our other drug candidates. If these third parties do not carry out their contractual duties, comply with regulatory requirements or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialise our drug candidates and our business could be substantially harmed.
If we fail to comply with our obligations under our existing intellectual property licence agreements or under any future intellectual property licences, or otherwise experience disruptions to our business relationships with our current or any future licensors, we could lose intellectual property rights that are important to our business.
If we fail to comply with our obligations under our existing or future collaboration agreements, or otherwise experience disruptions to our business relationships with our prior, current, or future collaborators, we could lose intellectual property rights that are important to our business.
If we are unable to obtain, maintain, enforce and protect patent protection for our technology and drug candidates or if the scope of the patent protection obtained is not sufficiently broad, our competitors could develop and commercialise technology and products similar or identical to ours, and our ability to successfully develop and commercialise our technology and drug candidates may be adversely affected.
Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified personnel.
As a company headquartered and with operations outside of the United States, we are subject to economic, political, regulatory and other risks associated with international operations.
Compliance with stringent and evolving global privacy and data security requirements could result in additional costs and liabilities to us or inhibit our ability to collect and process data globally, and the failure to comply with such requirements could subject us to significant fines and penalties, which may have a material adverse effect on our business, financial condition or results of operations.

Risks Related to Our Financial Position
We have a history of significant operating losses, and we expect to incur losses over the next several years.
We have a history of significant operating losses. Our net losses before taxation were £162.1 million for the year ended December 31, 2023. As of December 31, 2023, we had accumulated total losses of £349.5 million since inception. We are still in the early stages of development of our own drug discovery programmes. We have no drug products licensed for commercial sale and have not generated any revenue from our own drug product sales to date. We expect to continue to incur significant expenses and operating losses over the next several years. Our operating expenses and net losses may fluctuate significantly from quarter-to-quarter and year-to-year. We anticipate that our expenses will increase substantially as we:
continue to invest in and develop our computational platform and software solutions;
continue our research and development efforts for our internal and joint arrangement drug discovery programmes;
conduct preclinical studies, submit investigational new drug applications, or INDs, and comparable foreign applications, and conduct clinical trials for any of our current or future drug candidates;
seek marketing approvals for any drug candidates that successfully complete clinical trials;
establish a sales, marketing and distribution infrastructure and scale-up manufacturing capabilities, whether alone or with third parties, to commercialise any drug candidates for which we may obtain regulatory approval, if any;
maintain, expand, enforce, defend and protect our intellectual property;
hire additional software engineers, programmers, sales and marketing and other personnel to support the development of our software solutions;
hire additional clinical, quality control and other scientific personnel;
experience any delays or encounter any issues with any of the above, including but not limited to failed studies, complex results, safety issues or other regulatory challenges;
acquire and integrate new technologies, businesses or other assets; and
add operational, financial and management information systems and personnel to support our operations as a public company.
Our operating history may make it difficult for you to evaluate the success of our business to date and to assess our future viability.
We commenced operations in July 2012, and our operations to date have been limited to organizing and staffing our company, business planning, raising capital, conducting discovery and research activities, developing our drug discovery platform, filing patent applications, identifying potential drug candidates, undertaking research activities and identifying and entering into collaborations that would allow us to further develop viable drug candidates. We have not yet demonstrated our ability to successfully complete any clinical trials, obtain marketing approvals, manufacture a commercial-scale product or arrange for a third party to do so on our behalf, or conduct sales, marketing and distribution activities necessary for successful product commercialisation. Consequently, any predictions you make about our future success or viability may not be as accurate as they could be if we had a longer operating history.
In addition, as an early-stage company, we may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown factors. We will need to transition at some point from a company with a research and development focus to a company capable of supporting commercial activities. We may not be successful in such a transition.

If we and our present and future collaborators are unable to successfully develop and commercialise drug products, our revenues may be insufficient for us to achieve or maintain profitability.
We have never generated revenue from drug product sales and our most advanced drug candidate is in a Phase 1/2 clinical trial. We currently generate revenue primarily from upfront and milestone payments under our agreements with our collaborators. To achieve and maintain profitability, we must succeed in developing, and eventually commercialising, a drug product or drug products that generate significant revenue. As such, we will be dependent on the ability of our platform to identify promising molecules for preclinical and clinical development. Achieving success in drug development will require us and our collaborators to be effective in a range of challenging activities, including completing preclinical testing and clinical trials of drug candidates, obtaining regulatory approval for these drug candidates and manufacturing, marketing and selling any products for which we or our collaborators may obtain regulatory approval. All our wholly owned drug candidates and those that we have developed with our collaborators are in the preliminary stages of most of these activities. We and they may never succeed in these activities and, even if we or they do, we may never generate revenues that are significant enough to achieve profitability. Because of the intense competition that our technology platform faces in the market and the numerous risks and uncertainties associated with biopharmaceutical product development, we are unable to accurately predict when, or if, we will be able to achieve or sustain profitability.
Even if we achieve profitability, we may not be able to sustain or increase profitability. Our failure to become and remain profitable would depress the value of our company and could impair our ability to raise capital, expand our business, maintain our research and development efforts, increase sales of our software, develop a pipeline of drug candidates, enter into collaborations or even continue our operations. A decline in the value of our company could also cause you to lose all or part of your investment.
Our interim and annual results may fluctuate significantly, which could adversely impact the value of our ADSs.
Our results of operations, including our revenues, gross profit, profitability and cash flows, have historically varied from period-to-period, and we expect that they will continue to do so. As a result, period-to-period comparisons of our operating results may not be meaningful, and our interim and annual results should not be relied upon as an indication of future performance. Our interim and annual financial results may fluctuate as a result of a variety of factors, many of which are outside of our control. Factors that may cause fluctuations in our interim and annual financial results include, without limitation, those listed elsewhere in this “Risk Factors” section and those listed below:
the amount and timing of operating expenses related to the maintenance and expansion of our business, operations and infrastructure;
the success of our drug discovery collaborators in developing and commercialising drug products for which we are entitled to receive upfront payments, milestone or royalty payments and the timing of receipt of such payments, if any;
our ability to enter into new collaboration agreements;
our ability to collect receivables from our collaborators;
unforeseen business disruptions that increase our costs or expenses;
the timing and success of the introduction of new software solutions by us or our competitors or any other change in the competitive dynamics of our industry, including consolidation among competitors, customers or strategic collaborators;
changes in the fair value of or receipt of distributions or proceeds on account of the equity interests we hold in our drug discovery collaborators;
future accounting pronouncements or changes in our accounting policies;
general economic, industry and market conditions, including within the life sciences industry; and
9

Table of Contents
the timing and amount of expenses related to our drug discovery programmes, the development or acquisition of technologies or businesses and potential future charges for impairment of goodwill from acquired companies.

We may need additional funding in the future which may not be available on terms acceptable to us, or at all. If we are unable to raise additional capital or to generate cash flows necessary to maintain or expand our operations, we may not be able to compete successfully, which would harm our business, operations, financial condition and prospects.
We expect to devote substantial financial resources to our ongoing and planned activities, including the development of our current and future drug discovery programmes and continued investment in our technology platform. We expect our expenses to increase substantially in connection with these activities, particularly as we advance our internal drug discovery programmes, initiate and complete preclinical and investigational new drug enabling studies, and invest in the further development of our platform.
We and our current drug discovery collaborators, from whom we are entitled to receive milestone payments upon achievement of various development, regulatory and commercial milestones as well as royalties on commercial sales, if any, under the collaboration agreements that we have entered into with them, face numerous risks in the development of drugs, including conducting preclinical and clinical tests, obtaining regulatory approval and achieving product sales. In addition, the amounts we are entitled to receive upon the achievement of such milestones tend to be smaller for near-term development milestones and increase if and as a collaborative drug candidate advances through development to commercialisation and will vary depending on regulatory approval and the level of commercial success achieved, if any. Accordingly, we may need to obtain substantial additional capital to fund our continuing operations.
As of December 31, 2023, we had cash, cash equivalents and short term bank deposits of £363.0 million. We believe that our existing cash, cash equivalents and short term bank deposits will be sufficient to fund our operations and capital expenditure requirements for at least the next twelve months. However, we have based this estimate on assumptions that may prove to be wrong, and our operating plans may change as a result of many factors currently unknown to us. As a result, we could deplete our capital resources sooner than we currently expect. Our future capital requirements will depend on many factors, including:
the scope, timing, progress and extent of spending to support research and development efforts of our drug candidates, including preclinical studies and clinical trials;
the costs, timing and outcome of regulatory review of our drug candidates;
the development requirements of other drug candidates that we may pursue;
the costs of acquiring, licensing or investing in drug discovery technologies;
the timing and receipt of payments from our collaborations;
our ability to establish additional discovery collaborations on favourable terms, if at all;
the timing and receipt of any distributions or proceeds we may receive from our equity stakes in companies;
the costs of preparing, filing and prosecuting patent applications, obtaining, maintaining, enforcing and protecting our intellectual property rights and defending intellectual-property-related claims;
the costs of expanding our operations, including our sales and marketing efforts to drive market recognition of our platform and address competitive developments;
the costs of future commercialisation activities, including product sales, marketing, manufacturing and distribution, for any drug candidate for which we receive marketing approval;
the impacts of the global geopolitical tension, supply chain disruptions, worsening macroeconomic conditions, including rising interest rates and inflation; and
the costs of operating as a public company.

In the event that we require additional financing, we may not be able to raise such financing on terms acceptable to us or at all. In addition, we may seek additional capital due to favourable market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans. If we are unable to raise additional capital on terms acceptable to us or at all or generate cash flows necessary to maintain or expand our operations and invest in our computational platform, we may not be able to compete successfully, which would harm our business, financial condition, results of operations and prospects.
Unfavourable global economic and geopolitical conditions could adversely affect our business, financial condition or results of operations.
Our financial condition or results of operations could be adversely affected by general conditions in the global economy and in the global financial markets or by geopolitical events such as the war in Ukraine war or the conflict between Hamas and Israel. For example, inflation rates, particularly in the United States and the U.K., increased in 2023 to levels not seen in decades. Increased inflation, even if rates are decreasing, may result in increased operating costs (including labour costs) and may affect our operating budgets. A weak or declining economy could strain our suppliers, possibly resulting in supply disruption, or cause delays in payments for our services by third-party payors or our collaborators. While the long-term economic impact of either the war in Ukraine or the conflict between Hamas and Israel is difficult to assess or predict, each of these events has caused significant disruptions to the global financial markets. In addition, our potential collaborators’ businesses and cash flows have recently been and may continue to be negatively impacted by the global economic developments and geopolitical uncertainty which has led and may continue to lead to a decreased willingness to enter into new research and development partnerships and collaborations across the life sciences industry. If the disruptions and slowdown deepen or persist, we may not be able to enter into new collaboration agreements or to raise any additional financing on terms acceptable to us or at all. Any of the foregoing could harm our business and we cannot anticipate all of the ways in which the current economic climate and financial market conditions could adversely impact our business.

Risks Related to the Discovery and Development of Our Drug Candidates
We are substantially dependent on our technology platform to identify promising molecules to accelerate drug discovery and development. Our platform technology may fail to discover and design molecules with therapeutic potential or may not result in the discovery and development of commercially viable products for us or our collaborators.
We use our technology platform to conduct AI-enabled laboratory experimentation and our technology platform underpins all our efforts. As a result, the quality and sophistication of our platform and technology is critical to our ability to conduct our research discovery activities, to design and deliver promising molecule candidates and to accelerate and lower the cost of drug discovery as compared to traditional methods for our partnerships. We originated the first three AI-designed precision drugs to enter human clinical trials. Because AI-designed drug candidates are novel, there is greater uncertainty about our ability to develop, advance and commercialise drug candidates using our AI-design process.
While the results of certain of our internal drug discovery programmes and drug discovery collaborations suggest that our platform is capable of accelerating drug discovery and identifying high-quality drug candidates, these results do not assure future success for our drug discovery collaborators or for us with our internal drug discovery programmes. Even if we or our drug discovery collaborators are able to develop drug candidates that demonstrate potential in preclinical studies, we or they may not succeed in
11

Table of Contents
demonstrating safety and efficacy of these drug candidates in human clinical trials. Moreover, preclinical and clinical data are susceptible to error and inaccurate or varying interpretations and analyses, and many companies that believed their drug candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval of their drug candidates.

All of our drug candidates are in early-stage clinical development or in preclinical development. If we are unable to advance our drug candidates through clinical development, to obtain regulatory approval and ultimately to commercialise our drug candidates, or if we experience significant delays in doing so, our business will be materially harmed.
Four drug candidates that we have developed are currently in clinical trials: The Phase 1/2 clinical trial of GTAEXS617, our jointly owned candidate with GT Apeiron ("GTA"), commenced in July 2023. BMY-licensed EXS4318 and an additional two compounds that we developed for one of our collaborators for which we have no economic interest are all currently in clinical trials. Thus far, no approved therapeutics have been developed using AI. There is no assurance that any current or future clinical trials of our drug candidates will be successful or will generate positive clinical data, and we may not receive marketing approval from the U.S. Food and Drug Administration, or FDA, or other regulatory authorities for any of our drug candidates. We have never submitted an IND to the FDA. Our other drug candidates are in preclinical development. There can be no assurance that the FDA will permit the INDs for any of our drug candidates to go into effect in a timely manner or at all.
Biopharmaceutical development is a long, expensive and uncertain process, and delay or failure can occur at any stage of any of our clinical trials. Failure to obtain regulatory approval for our drug candidates will prevent us from commercialising and marketing our drug candidates. Successful development of our drug candidates will depend on many factors, including:
completing preclinical studies;
submission of INDs and comparable foreign applications for and receipt of allowance to proceed with our planned clinical trials or other future clinical trials;
initiating, enrolling and completing clinical trials;
obtaining positive results from our preclinical studies and clinical trials that demonstrate safety and efficacy for our drug candidates;
receiving approvals for commercialisation of our drug candidates from applicable regulatory authorities;
establishing sales, marketing and distribution capabilities and successfully launching commercial sales of our products, if and when approved, whether alone or in collaboration with others;
making arrangements with third-party manufacturers for, or establishing, clinical and commercial manufacturing capabilities;
manufacturing our drug candidates at an acceptable cost;
acceptance of our products, if and when approved, by patients, the medical community and third-party payors; and
maintaining and growing an organisation of scientists, medical professionals and businesspeople who can develop and commercialise our products and technology.
Many of these factors are beyond our control, including the time needed to adequately complete clinical testing and the regulatory submission process. It is possible that none of our drug candidates will ever obtain regulatory approval, even if we expend substantial time and resources seeking such approval. If we do not achieve one or more of the above-listed requirements in a timely manner or at all, or if any other factor impacts the successful development of biopharmaceutical products, we could experience significant delays or an inability to successfully develop our drug candidates, which would materially harm our business, financial condition, results of operations and prospects.

Clinical development involves a lengthy and expensive process with uncertain outcomes. If our preclinical studies and clinical trials are not sufficient to support regulatory approval of any of our drug candidates, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development of such drug candidate.
All of our drug candidates are in preclinical development or early-stage clinical trials and their risk of failure is high. Clinical testing is expensive, is difficult to design and implement, can take many years to complete and has an uncertain outcome. We cannot guarantee that any of our clinical trials will be conducted as planned or completed on schedule, or at all. A failure of one or more clinical trials can occur at any stage of testing, which may result from a multitude of factors, including, but not limited to, flaws in trial design, dose selection issues, participant enrolment criteria and failure to demonstrate favourable safety or efficacy traits.
Before we can commence clinical trials for a drug candidate, we must complete extensive preclinical testing and studies that support our planned INDs and other regulatory filings in the United States and abroad. We cannot be certain of the timely completion or outcome of our preclinical testing and studies and cannot predict if regulatory authorities will accept our proposed clinical programmes or if the outcome of our preclinical testing and studies will ultimately support the further development of any drug candidates. As a result, we cannot be sure that we will be able to submit INDs or corresponding regulatory filings for our preclinical programmes on the timelines we expect, if at all, and we cannot be sure that submission of INDs or non-U.S. regulatory filings will result in regulatory authorities allowing clinical trials to begin.
The time required to obtain approval from the FDA, the European Commission, or other non-U.S. regulatory authorities is unpredictable but typically takes many years following the commencement of clinical trials and depends upon numerous factors, including the substantial discretion of regulatory authorities. Before obtaining marketing approval from regulatory authorities for the sale of any drug candidate, we must complete preclinical development and then conduct extensive clinical trials to demonstrate the safety and efficacy of such drug candidate in humans. Clinical trials may fail to demonstrate that our drug candidates are safe and effective for indicated uses. Even if the clinical trials are successful, changes in marketing approval policies during the development period, changes in or the enactment or promulgation of additional statutes, regulations or guidance or changes in regulatory review for each submitted product application may cause delays in the approval or rejection of an application.
Furthermore, drug candidates are subject to continued preclinical safety studies, which may be conducted concurrently with our clinical testing. The outcomes of these safety studies may delay the launch of or enrolment in future clinical trials and could impact our ability to continue to conduct our clinical trials.
Other events that may prevent successful or timely completion of clinical development include:
inability to generate sufficient preclinical, toxicology or other in vivo or in vitro data to support the initiation of clinical trials;
delays in reaching a consensus with regulatory authorities on trial design;
delays in reaching agreement on acceptable terms with prospective contract research organisations, or CROs and clinical trial sites;
delays in opening clinical trial sites or obtaining required institutional review board, or IRB, or institutional biosafety committee, or IBC, approval, or a positive opinion from an ethics committee, or that of the equivalent review groups for sites outside the United States, at each clinical trial site;
imposition of a clinical hold by regulatory authorities, including as a result of a serious adverse event or after an inspection of our clinical trial operations or trial sites;
failure by us, any CROs we engage or any other third parties to adhere to clinical trial requirements;
failure to perform in accordance with Good Clinical Practices, or GCPs;
failure by investigators and clinical sites to adhere to protocols leading to variable results;
13

Table of Contents
failure of our delivery approach in humans;
delays in the testing, validation, manufacturing and delivery of our drug candidates to the clinical sites, including delays by third parties with whom we have contracted to perform certain of those functions;
failure of our third-party contractors to comply with regulatory requirements or to meet their contractual obligations to us in a timely manner, or at all;
inability to enrol participants or delays in having enrolled participants complete their participation in a trial or return for post-administration follow-up;
clinical trial sites or participants dropping out of a trial;
selection of clinical endpoints that require prolonged periods of clinical observation or analysis of the resulting data;
clinical trials of our drug candidates may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional clinical trials or abandon development programmes;
occurrence of serious adverse events associated with the drug candidate or administration of the drug candidate that are viewed to outweigh its potential benefits;
occurrence of serious adverse events or other unexpected events in trials of the same class of agents conducted by other sponsors;
changes in regulatory requirements and guidance that require amending or submitting new clinical trial protocols;
changes in the legal or regulatory regimes domestically or internationally related to patient rights and privacy; or
lack of adequate funding to continue a given clinical trial.
Any inability to successfully complete preclinical studies and clinical trials could result in additional costs to us or impair our ability to generate revenues from product sales, regulatory and commercialisation milestones and royalties. In addition, if we make manufacturing or formulation changes to our drug candidates, we may need to conduct additional preclinical studies or clinical trials to bridge our modified drug candidates to earlier versions. Clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialise our drug candidates or allow our competitors to bring products to market before we do, which could impair our ability to successfully commercialise our drug candidates and may harm our business, financial condition, results of operations and prospects.
Our research activities and clinical trials may fail to demonstrate adequately the safety and efficacy of GTAEXS617 or any other drug candidate, which would prevent or delay development, regulatory approval and commercialisation.
Before obtaining regulatory approvals for the commercial sale of any drug candidate, including GTAEXS617, we must demonstrate, through lengthy, complex and expensive research activities and clinical trials, that our drug candidates are both safe and effective for use in each target indication. Research activities and clinical testing is expensive and can take many years to complete and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial processes, and, because GTAEXS617 is in early stages of development, there is a high risk of failure and we may never succeed in developing it as a marketable product.
Any clinical trial that we may conduct may not demonstrate the safety and efficacy necessary to obtain regulatory approval to market our drug candidates. If the results of our ongoing or future clinical trials are inconclusive with respect to the safety, potency, purity and efficacy of our drug candidates, if we do not meet the clinical endpoints with statistical and clinically meaningful significance, or if there are safety concerns associated with our drug candidates, we may be prevented from or delayed in obtaining marketing approval for such drug candidates. In some instances, there can be significant variability in safety and efficacy results between different clinical trials of the same drug candidate due to numerous
14

Table of Contents
factors, including changes in trial procedures set forth in protocols, manufacturing variances, differences in the size and type of the patient populations, changes in and adherence to the clinical trial protocols and the rate of dropout among clinical trial participants.

We have successfully completed only one clinical trial, and we may be unable to do so again for any drug candidates we develop.
We have successfully completed only one clinical trial, and we have not yet demonstrated our ability to successfully obtain a regulatory approval, manufacture a commercial-scale product or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful commercialisation of a drug candidate. We may not be able to file any additional CTAs or any INDs for our drug candidates on the timelines we expect, if at all. Moreover, we cannot be sure that submission of an IND or comparable foreign application will result in the FDA, or non-U.S. regulatory authority, allowing further clinical trials to begin, or that, once begun, issues will not arise that require us to suspend, vary or terminate clinical trials. Commencing each of these clinical trials is subject to finalizing the trial design based on discussions with the FDA and other regulatory authorities. Any guidance we receive from regulatory authorities is subject to change. For example, a regulatory authority could change its position, including on the acceptability of our trial designs or the clinical endpoints selected, which may require us to complete additional clinical trials or impose stricter approval conditions than we currently expect.
If we are required to conduct additional preclinical studies or clinical trials or other testing of our drug candidates beyond those that we currently contemplate, if we are unable to successfully complete clinical trials of our drug candidates or other testing, if the results of these trials or tests are not positive or are only modestly positive or if there are safety concerns, we may:
be delayed in obtaining marketing approval for our drug candidates;
not obtain marketing approval at all;
obtain approval for indications or patient populations that are not as broad as intended or desired;
be subject to post-marketing testing requirements; or
have the product removed from the market after obtaining marketing approval.

We may incur additional costs or experience delays in initiating or completing, or ultimately be unable to complete, the development and commercialisation of our drug candidates.
We may experience delays in initiating or completing our preclinical studies and clinical trials, including as a result of delays in obtaining, or failure to obtain, the FDA’s or comparable non-U.S. regulatory authorities' clearance to initiate clinical trials under future INDs or comparable non-U.S. applications. Additionally, we cannot be certain that preclinical studies or clinical trials for our drug candidates will not require redesign, enrol an adequate number of subjects on time or be completed on schedule, if at all. We may experience numerous unforeseen events during, or as a result of, preclinical studies and clinical trials that could delay or prevent our ability to receive marketing approval or commercialise our drug candidates, including:
we may receive feedback from regulatory authorities that requires us to modify the design or implementation of our preclinical studies or clinical trials;
regulators or IRBs may not authorise us or our investigators, or ethics committees may not issue positive opinions permitting us or our investigators, to commence a clinical trial or conduct a clinical trial at a prospective trial site;
we may experience delays in reaching, or fail to reach, agreement on acceptable terms with prospective trial sites and prospective CROs, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;

our third-party contractors may fail to comply with regulatory requirements, fail to maintain adequate quality controls, be unable to provide us with sufficient product supply to conduct or complete preclinical studies or clinical trials, or fail to meet their contractual obligations to us in a timely manner, or at all, or may deviate from the clinical trial protocol or drop out of the trial, which may require that we add new clinical trial sites or investigators;
we may elect to, or regulators, IRBs or ethics committees may require us or our investigators to, suspend or terminate clinical research for various reasons, including noncompliance with regulatory requirements or a finding that the participants are being exposed to unacceptable health risks;
the cost of clinical trials of our drug candidates may be greater than we anticipate;
the supply or quality of our drug candidates or other materials necessary to conduct clinical trials of our drug candidates may be insufficient or inadequate;
our drug candidates may have undesirable side effects or other unexpected characteristics, causing us or our investigators, or regulators, IRBs or ethics committees to suspend or terminate the trials, or reports may arise from preclinical or clinical testing of other cancer therapies that raise safety or efficacy concerns about our drug candidates; and
regulatory authorities may revise the requirements for approving our drug candidates, or such requirements may not be as we anticipate.
We could encounter delays if a clinical trial is suspended or terminated by us, by the IRBs or ethics committees of the institutions at which such trials are being conducted, by the Data Safety Monitoring Board, or DSMB, for such trials or by the FDA or other regulatory authorities. Such authorities may impose such a suspension or termination or clinical hold due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a product, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. Many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our drug candidates. Further, the FDA or comparable non-U.S. regulatory authorities may disagree with our clinical trial design and our interpretation of data from clinical trials, or may change the requirements for approval even after it has reviewed and commented on the design for our clinical trials.
Moreover, principal investigators for our current and future clinical trials may serve as scientific advisors or consultants to us from time to time and receive compensation in connection with such services. Under certain circumstances, we may be required to report some of these relationships to the FDA or comparable non-U.S. regulatory authorities. The FDA or comparable non-U.S. regulatory authority may conclude that a financial relationship between us and a principal investigator has created a conflict of interest or otherwise affected the interpretation of the study. The FDA or comparable non-U.S. regulatory authority may therefore question the integrity of the data generated at the applicable clinical trial site and the utility of the clinical trial itself may be jeopardised. This could result in a delay in approval, or rejection, of our marketing applications by the FDA or comparable non-U.S. regulatory authority, as the case may be, and may ultimately lead to the denial of marketing approval of one or more of our drug candidates.

Our product development costs will also increase if we experience delays in testing or obtaining regulatory approvals. We do not know whether any of our future clinical trials will begin as planned, or whether any of our current or future clinical trials will need to be restructured or will be completed on schedule, if at all. Significant preclinical study or clinical trial delays could also shorten any periods during which we may have the exclusive right to commercialise our drug candidates or allow our competitors to bring products to market before we do and impair our ability to successfully commercialise our drug candidates. Any delays in our preclinical or future clinical development programmes may harm our business, financial condition and growth prospects significantly.

If we experience delays or difficulties in the enrolment of patients in clinical trials, our receipt of necessary regulatory approvals could be delayed or prevented.
We may not be able to initiate or continue clinical trials for our drug candidates if we are unable to locate and enrol a sufficient number of eligible patients to participate in these trials as required by the FDA or similar regulatory authorities outside the United States. In particular, because we are deploying our drug discovery platform across a broad target space, our ability to enrol eligible patients may be limited or may result in slower enrolment than we anticipate. For example, because some of our drug candidates target rare diseases, we may have difficulty enrolling a sufficient number of eligible patients or enrolment may be slower than we anticipate. In addition, some of our competitors have ongoing clinical trials for drug candidates that treat the same indications as our drug candidates, and patients who would otherwise be eligible for our clinical trials may instead enrol in clinical trials of our competitors’ drug candidates.
In addition to the competitive trial environment, the eligibility criteria of our planned clinical trials will further limit the pool of available study participants as we will require that patients have specific characteristics that we can measure to assure their cancer is either severe enough or not too advanced to include them in a study. We may not be able to identify, recruit and enrol a sufficient number of patients to complete our clinical studies for a number of reasons, including:
the severity of the disease under investigation;
the eligibility criteria and overall design of the clinical trial in question;
the perceived risks and benefits of the drug candidate under study;
clinicians’ and patients’ perceptions as to the potential advantages of the drug candidate being studied in relation to other available therapies, including any new drugs that may be approved for the indications we are investigating;
the ability to obtain and maintain patient consents;
the efforts to facilitate timely enrolment in clinical trials;
the patient referral practices of physicians;
the size and nature of the patient population required for analysis of the trial’s primary endpoints;
the ability to monitor patients adequately during and after treatment;
the proximity and availability of clinical trial sites for prospective patients;
the risk that patients enrolled in clinical trials will drop out of the clinical trials before completion of their treatment; and
factors we may not be able to control, such as potential future pandemics that may limit patients, principal investigators, staff or clinical site availability.
Delays in patient enrolment may result in increased costs or may affect the timing or outcome of the planned clinical trials, which could prevent completion of these clinical trials and adversely affect our ability to advance the development of our drug candidates. In addition, many of the factors that may lead to a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our drug candidates.

Success in preclinical studies or clinical trials may not be predictive of results in future clinical trials.
Positive results from early preclinical studies and clinical trials of our drug candidates are not necessarily predictive of the results of later preclinical studies and any future clinical trials of our drug candidates. Even if we are able to complete our planned preclinical studies and clinical trials of our drug candidates according to our current development timeline, the results from such preclinical studies and clinical trials of our drug candidates may not be replicated in subsequent preclinical studies or clinical trial results. If we cannot replicate such positive results in our later preclinical studies and future clinical trials, we may be unable to successfully develop, obtain regulatory approval for and commercialise our drug candidates. For example, we stopped the Phase 1/2 clinical trial of EXS21546 after receiving information demonstrating that the drug candidate was not sufficiently promising to justify further clinical development.
Many companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in late-stage clinical trials after achieving positive results in early-stage development, and we cannot be certain that we will not face similar setbacks. These setbacks have been caused by, among other things, preclinical and other non-clinical findings made while clinical trials were underway, or safety or efficacy observations made in preclinical studies and clinical trials, including previously unreported adverse events. Moreover, preclinical, non-clinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that believed their drug candidates performed satisfactorily in preclinical studies and clinical trials nonetheless failed to obtain FDA or European Commission approval.
Additionally, future clinical trials that we may plan might utilise an “open-label” trial design. An “open-label” clinical trial is one where both the patient and investigator know whether the patient is receiving the investigational drug candidate or either an existing approved drug or placebo. Most typically, open-label clinical trials test only the investigational drug candidate and sometimes may do so at different dose levels. Open-label clinical trials are subject to various limitations that may exaggerate any therapeutic effect as patients in open-label clinical trials are aware when they are receiving treatment. Open-label clinical trials may be subject to a “patient bias” where patients perceive their symptoms to have improved merely due to their awareness of receiving an experimental treatment. In addition, open-label clinical trials may be subject to an “investigator bias” where those assessing and reviewing the physiological outcomes of the clinical trials are aware of which patients have received treatment and may interpret the information of the treated group more favourably given this knowledge. The results from an open-label trial may not be predictive of future clinical trial results with any of our drug candidates for which we include an open-label clinical trial when studied in a controlled environment with a placebo or active control.

Interim, “topline,” and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data.
From time to time, we may publicly disclose preliminary or topline data from our clinical trials, which is based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular study or trial. We also make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the topline or preliminary results that we report may differ from future results of the same studies, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. Topline data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we
18

Table of Contents
previously published. As a result, topline data should be viewed with caution until the final data are available. From time to time, we may also disclose interim data from our clinical trials. Interim data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrolment continues and more patient data become available or as patients from our clinical trials continue other treatments for their disease. Adverse differences between preliminary or interim data and final data could significantly harm our business prospects. Further, disclosure of interim data by us or by our competitors could result in volatility in the price of the ADSs.
If the interim, topline, or preliminary data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialise, our drug candidates may be harmed, which could harm our business, financial condition, results of operations and prospects. In addition, the information we choose to publicly disclose regarding a particular clinical trial is based on what is typically extensive information, and you or others may not agree with what we determine is material or otherwise appropriate information to include in our disclosure.

Our current and future clinical trials or those of our current or future collaborators may reveal significant adverse events not seen in our preclinical or non-clinical studies and may result in a safety profile that could inhibit regulatory approval or market acceptance of any of our drug candidates.
Before obtaining regulatory approvals for the commercial sale of any products, we must demonstrate through lengthy, complex and expensive preclinical studies and clinical trials that our drug candidates are both safe and effective for use in each target indication. Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. There is typically an extremely high rate of attrition for drug candidates proceeding through clinical trials. Drug candidates in later stages of clinical trials also may fail to show the desired safety and efficacy profile despite having progressed through non-clinical studies and initial clinical trials. If the results of our ongoing or future preclinical studies and clinical trials are inconclusive with respect to the safety and efficacy of our drug candidates, if we do not meet the clinical endpoints with statistical and clinically meaningful significance, or if there are safety concerns associated with our drug candidates, we may be prevented from or delayed in obtaining marketing approval for such drug candidates. In some instances, there can be significant variability in safety or efficacy results between different clinical trials of the same drug candidate due to numerous factors, including changes in trial procedures set forth in protocols, differences in the size and type of the patient populations, changes in and adherence to the clinical trial protocols and the rate of dropout among clinical trial participants. While we have not yet initiated clinical trials for certain of our drug candidates, it is likely, as is the case with many oncology therapies, that there will be side effects associated with their use. Results of our trials could reveal a high and unacceptable severity and prevalence of side effects. Further, our drug candidates could cause undesirable side effects in clinical trials related to on-target toxicity. If on-target toxicity is observed, or if our drug candidates have characteristics that are unexpected, we may need to abandon their development or limit development to narrower uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective. In addition, our drug candidates could cause undesirable side effects that we have not observed yet to date. We also may develop future drug candidates for use in combination with one or more existing cancer therapies. The uncertainty resulting from the use of our drug candidates in combination with other cancer therapies may make it difficult to accurately predict side effects in future clinical trials. Most drug candidates that commence clinical trials are never approved as products and there can be no assurance that any of our current or future clinical trials will ultimately demonstrate positive results or support further clinical development of any of our drug candidates.
19

Table of Contents
If significant adverse events or other side effects are observed in any of our current or future clinical trials, we may have difficulty recruiting patients to our clinical trials, patients may drop out of our trials or we may be required to abandon the trials or our development efforts of one or more drug candidates altogether. We, the FDA or other applicable regulatory authorities, or an IRB or ethics committee may suspend or terminate clinical trials of a drug candidate at any time for various reasons, including a belief that subjects in such trials are being exposed to unacceptable health risks or adverse side effects. Some potential therapeutics that initially showed therapeutic promise in early-stage trials have later been found to cause side effects that prevented their further development. Even if the side effects do not preclude the product from obtaining or maintaining marketing approval, undesirable side effects may inhibit market acceptance of the approved product due to its tolerability versus other therapies. Any of these developments could materially harm our business, financial condition, results of operations and prospects.

We intend to develop GTAEXS617, and potentially other future drug candidates, for use in combination with other therapies, which exposes us to additional risks.
We intend to develop GTAEXS617 for use in combination with one or more currently approved cancer therapies. If a drug candidate we develop were to receive marketing approval for use in combination with these existing therapies, we would continue to bear the risks that the FDA or similar foreign regulatory authorities could revoke approval of the therapies used in combination with our drug candidate or that safety, efficacy, manufacturing or supply issues could arise with such existing therapies. We would be subject to similar risks if we develop any of our drug candidates for use in combination with other drugs or for indications other than cancer. This could result in our own products being removed from the market or being less successful commercially.
We may also potentially evaluate other drug candidates in combination with one or more other cancer therapies that have not yet been approved for marketing by the FDA or similar foreign regulatory authorities. We will not be able to market and sell any drug candidate we develop in combination with any such cancer therapies that do not ultimately obtain marketing approval whether alone or in combination with our product. In addition, unapproved cancer therapies face the same risks described with respect to our drug candidates currently in development and clinical trials, including the potential for serious adverse effects, delay in their clinical trials and lack of FDA or comparable non-U.S. regulatory authorities' approval. If safety, efficacy, manufacturing or supply issues arise with the products we choose to evaluate in combination with our drug candidates, we may be unable to obtain approval of or market such combination.

We currently, and may in the future, conduct clinical trials for our drug candidates outside the United States, and the FDA and similar foreign regulatory authorities may not accept data from such trials.
We are currently conducting clinical trials outside the United States, and we may in the future conduct clinical trials outside the United States, including in China, Australia, Europe, elsewhere in Asia or other foreign jurisdictions. The acceptance of trial data from clinical trials conducted outside the United States by the FDA or non-U.S. regulatory authorities may be subject to certain conditions. In cases where data from clinical trials conducted outside the United States are intended to serve as the sole basis for marketing approval in the United States, the FDA will generally not approve the application on the basis of such data alone unless (i) the data are applicable to the United States population and United States medical practice; (ii) the trials were performed by clinical investigators of recognised competence pursuant to GCP regulation; and (iii) the data may be considered valid without the need for an on-site inspection by the FDA or, if the FDA considers such an inspection to be necessary, the FDA is able to validate the data through an on-site inspection or other appropriate means. In general, the patient
20

Table of Contents
population for any clinical trials conducted outside the United States must be representative of the population for whom we intend to label the drug candidate in the United States. Additionally, the FDA’s clinical trial requirements, including sufficient size of patient populations and statistical powering, must be met. Many foreign regulatory bodies have similar approval requirements. In addition, such foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA or any similar foreign regulatory authority will accept data from trials conducted outside of the United States or the applicable jurisdiction. If the FDA or any similar foreign regulatory authority does not accept such data, it would result in the need for additional trials, which would be costly and time-consuming and delay aspects of our business plan, and which may result in our drug candidates not receiving approval or clearance for commercialisation in the applicable jurisdiction.

We may seek orphan drug designation for certain of our drug candidates, and we may be unsuccessful or may be unable to maintain the benefits associated with orphan drug designation, including the potential for market exclusivity.
As part of our business strategy, we may seek orphan drug designation for certain of our drug candidates, and such efforts may be unsuccessful. Regulatory authorities in some jurisdictions, including the United States and the European Union, may designate drugs for relatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may designate a drug as an orphan drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals annually in the United States, or a patient population of 200,000 or more in the United States where there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the United States. In the United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and user-fee waivers.
Similarly, in the European Union, Regulation (EC) No. 141/2000 provides that the European Commission, after receiving the positive opinion of the EMA’s Committee for Orphan Medicinal Products, may grant orphan drug designation to promote the development of drugs where their sponsor can establish that: (1) the product is intended for the diagnosis, prevention or treatment of life-threatening or chronically debilitating conditions; (2) either (a) such conditions affect not more than 5 in 10,000 persons in the European Union when the application is made, or (b) the product without the benefits derived from orphan status would not generate sufficient return in the European Union to justify the necessary investment in developing the medicinal product; and (3) there exists no satisfactory authorized method of diagnosis, prevention, or treatment of the condition that has been authorized in the European Union, or even if such method exists, the product will be of significant benefit to those affected by that condition. Orphan medicinal product designation entitles an applicant to incentives such fee reductions or fee waivers, protocol assistance, and access to the centralized marketing authorization procedure.
Generally, if a drug candidate with an orphan drug designation subsequently receives the first marketing approval in the United States or the European Union for the indication for which it has such designation, the drug is entitled to a period of marketing exclusivity, which precludes the FDA or the European Commission from approving another marketing application for the same drug and indication for that time period, except in limited circumstances. In the E.U., the EMA cannot accept another marketing authorization application or accept an application to extend an existing authorization for a similar product. The applicable period is seven years in the United States and ten years in the European Union. In the E.U., this ten year period may be extended by two years for medicinal products in relation to which the marketing authorization holder has complied with a related agreed pediatric investigation plan. No extension to any supplementary protection certificate can be granted on the basis of pediatric studies for
21

Table of Contents
orphan indications. No extension to any supplementary protection certificate can be granted on the basis of pediatric studies for orphan indications. Orphan medicinal product designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process. The exclusivity period in the European Union can be reduced to six years if, at the end of the fifth year, it is established that a drug no longer meets the criteria on the basis of which it received orphan drug designation, including if the drug is sufficiently profitable so that market exclusivity is no longer justified or where the prevalence of the condition has increased above the threshold.
Even if we obtain orphan drug exclusivity for a drug, that exclusivity may not effectively protect the drug from competition because different drugs can be approved for the same condition. Even after an orphan drug is approved, the FDA and the European Commission can subsequently approve another drug for the same condition if the FDA or the European Commission (as applicable) conclude that the later drug is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care. In addition, a designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. Moreover, orphan drug exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was materially defective. If, in either the United States or the European Union the manufacturer is unable to assure sufficient quantities of the drug to meet the needs of patients with the rare disease or condition, orphan designation may also be lost. Orphan drug designation neither shortens the development time or regulatory review time of a drug nor gives the drug any advantage in the regulatory review or approval process. While we may seek orphan drug designations for our drug candidates, we may never receive such designations. Even if we do receive such designations, there is no guarantee that we will receive approval of the product for the therapeutic indication for which orphan designation was granted.

Even if we receive regulatory approval for any of our drug candidates, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense. Additionally, our drug candidates, if approved, could be subject to post-market study requirements, marketing and labelling restrictions and even recall or market withdrawal if unanticipated safety issues are discovered following approval. In addition, we may be subject to penalties or other enforcement action if we fail to comply with regulatory requirements.
If the FDA or a comparable foreign regulatory authority approves any of our drug candidates, the manufacturing processes, labelling, packaging, distribution, import, export, adverse event reporting, storage, advertising, promotion, monitoring and recordkeeping for the product will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, establishment registration and listing, as well as continued compliance with current Good Manufacturing Practices, or cGMPs, and GCPs for any clinical trials that we conduct post-approval. Additionally, manufacturers are required to comply with extensive FDA, and comparable foreign regulatory authority requirements, including ensuring that quality control and manufacturing procedures conform to cGMP regulations and applicable product tracking and tracing requirements. Any regulatory approvals that we receive for our drug candidates may also be subject to limitations on the approved indicated uses for which the product may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing studies, including Phase 4 clinical trials, and surveillance to monitor the safety and efficacy of the product. A product may not be promoted for uses that are not approved by the FDA or such other regulatory authorities as reflected in the product’s approved labelling, although physicians may, in their independent medical judgement, prescribe legally available products for “off-label” uses. If any of our current or future drug candidates is approved for marketing, and we are found to have improperly promoted off-label uses of those products, we may become subject to significant liability. The FDA may also require a Risk Evaluation and Mitigation
22

Table of Contents
Strategy, or REMS, to approve our drug candidates, which could entail requirements for a medication guide, physician communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient registries and other risk minimisation tools. Similar strategies may be required by non-U.S. authorities. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things:
restrictions on marketing or manufacturing of the product, withdrawal of the product from the market, or voluntary or mandatory product recalls;
manufacturing delays and supply disruptions where regulatory inspections identify noncompliance requiring remediation;
revisions to the labelling, including limitation on approved uses or the addition of warnings, contraindications or other safety information, including boxed warnings;
imposition of a REMS, or comparable foreign strategies, which may include distribution or use restrictions;
requirements to conduct additional post-market clinical trials to assess the safety of the product;
clinical trial holds;
fines, warning letters or other regulatory enforcement action;
refusal by the FDA or comparable foreign regulatory authority to approve pending applications or supplements to approved applications filed by us or suspension, variation or revocation of approvals;
product seizure or detention, or refusal to permit the import or export of products; and
injunctions or the imposition of civil or criminal penalties.


The FDA’s and other regulatory authorities’ policies may change, and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our drug candidates.
The policies of the FDA, the competent authorities of the E.U. Member States, the EMA, the European Commission and other comparable regulatory authorities responsible for clinical trials may change and additional government regulations may be enacted. For instance, the regulatory landscape related to clinical trials in the E.U. recently changed. The E.U. Clinical Trials Regulation, or CTR, which was adopted in April 2014 and repeals the E.U. Clinical Trials Directive, became applicable on January 31, 2022. The CTR allows sponsors to make a single submission to both the competent authority and an ethics committee in each E.U. Member State, leading to a single decision for each E.U. Member State. The assessment procedure for the authorization of clinical trials has been harmonized as well, including a joint assessment by all E.U. Member States concerned, and a separate assessment by each E.U. Member State with respect to specific requirements related to its own territory, including ethics rules. Each E.U. Member State’s decision is communicated to the sponsor via the centralized E.U. portal. Once the clinical trial approved, clinical study development may proceed. The CTR foresees a three-year transition period. The extent to which ongoing and new clinical trials will be governed by the CTR varies. For clinical trials in relation to which application for approval was made on the basis of the Clinical Trials Directive before January 31, 2023, the Clinical Trials Directive will continue to apply on a transitional basis until January 31, 2025. By that date, all ongoing trials will become subject to the provisions of the CTR. The CTR will apply to clinical trials from an earlier date if the related clinical trial application was made on the basis of the CTR or if the clinical trial has already transitioned to the CTR framework before January 31, 2025. Compliance with the CTR requirements by us and our third-party service providers, such as CROs, may impact our developments plans.
23

Table of Contents
In light of the entry into application of the CTR on January 31, 2022, we may be required to transition clinical trials for which we have obtained regulatory approvals in accordance with the CTD to the regulatory framework of the CTR. Transition of clinical trials governed by the CTD to the CTR will be required for clinical trials which will have at least one site active in the E.U. on January 30, 2025. A transitioning application would need to be submitted to the competent authorities of E.U. Member States through the Clinical Trials Information Systems and related regulatory approval obtained to continue the clinical trial past January 30, 2025. This would require financial, technical and human resources. If we are unable to transition our clinical trials in time, the conduct of those clinical trials may be negatively impacted.
It is currently unclear to what extent the U.K. will seek to align its regulations with the E.U. in the future. The U.K. regulatory framework in relation to clinical trials is derived from existing E.U. legislation (as implemented into U.K. law, through secondary legislation). On January 17, 2022, the U.K. Medicines and Healthcare products Regulatory Agency, or MHRA, launched an eight-week consultation on reframing the U.K. legislation for clinical trials. The U.K. Government published its response to the consultation on March 21, 2023 confirming that it would bring forward changes to the legislation. These resulting legislative amendments will determine how closely the U.K. regulations will align with the CTR. Failure of the U.K. to closely align its regulations with the E.U. may have an effect on the cost of conducting clinical trials in the U.K. as opposed to other countries and/or make it harder to seek a marketing authorization for the Company's product candidates on the basis of clinical trials conducted in the U.K..
In addition, on April 26, 2023, the European Commission adopted a proposal for a new Directive and Regulation to revise the existing pharmaceutical legislation. If adopted in the form proposed, the recent European Commission proposals to revise the existing E.U. laws governing authorization of medicinal products may result in a decrease in data and market exclusivity opportunities for our product candidates in the E.U. and make them open to generic or biosimilar competition earlier than is currently the case with a related reduction in reimbursement status.
Moreover, in December 2023, the E.U. Parliament and the Council reached a provisional agreement on the “AI Act” which is intended to introduce legislation governing the development, placing on the market and use of artificial intelligence in the E.U.. If adopted, we may be subject to additional regulatory requirements under the AI Act.
If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may not be able to obtain, may suffer a delay in obtaining, or lose any marketing approval that we may have obtained, which would adversely affect our business, financial condition, results of operations and prospects.

Obtaining and maintaining regulatory approval of our drug candidates in one jurisdiction does not mean that we will be able to obtain regulatory approval of our drug candidates in other jurisdictions.
We may submit marketing applications in countries in addition to the United States. Regulatory authorities in jurisdictions outside of the United States have requirements for approval of drug candidates with which we must comply prior to marketing in those jurisdictions. Obtaining foreign regulatory approvals and compliance with foreign regulatory requirements could result in significant difficulties and costs for us and could delay or prevent the introduction of our products in certain countries. If we fail to comply with the regulatory requirements in international markets and/or receive applicable marketing approvals, our target market will be reduced and our ability to realise the full market potential of our drug candidates will be harmed.
24

Table of Contents
Obtaining and maintaining regulatory approval of our drug candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain regulatory approval in any other jurisdiction, while a failure or delay in obtaining regulatory approval in one jurisdiction may have a negative effect on the regulatory approval process in others. For example, even if the FDA grants marketing approval of a drug candidate, comparable regulatory authorities in foreign jurisdictions must also approve the manufacturing, marketing and promotion of the drug candidate in those countries. Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from, and greater than, those in the U.S., including additional preclinical studies or clinical trials, as clinical trials conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In short, the foreign regulatory approval process involves all the risks associated with FDA approval. In many jurisdictions outside the U.S., a drug candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we may intend to charge for our products will also be subject to approval.

Risks Related to Our Business
We may not be successful in our efforts to identify or discover drug candidates and may fail to capitalise on programmes, collaborations or drug candidates that may present a greater commercial opportunity or for which there is a greater likelihood of success.
Research programmes to identify new drug candidates require substantial technical, financial and human resources. We may fail to identify additional potential drug candidates for clinical development. A failure to demonstrate the utility of our platform by using it ourselves to discover drug candidates for internal development could harm our business prospects.Because we have limited resources, we focus our research programmes on targets where we believe our computational assays are predictive for experimental assays, where we believe it is theoretically possible to discover a molecule with properties that are required for the molecule to become a drug and where we believe there is a meaningful commercial opportunity, among other factors. Currently, the focus of our internal drug discovery programmes is in the areas of oncology, immunology and anti-virals. We may forego or delay pursuit of opportunities with certain programmes, collaborations or drug candidates or for indications that later prove to have greater commercial potential. However, the development of any drug candidate we pursue may ultimately prove to be unsuccessful or less successful than another potential drug candidate that we might have chosen to pursue on a more aggressive basis with our capital resources. If we do not accurately evaluate the commercial potential for a particular drug candidate, we may relinquish valuable rights to that drug candidate through strategic collaboration, partnership, licensing or other arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialisation rights to such drug candidate. Alternatively, we may allocate internal resources to a drug candidate in a therapeutic area in which it would have been more advantageous to enter into a collaboration.

We face substantial competition, which may result in others discovering, developing or commercialising products before or more successfully than we do.
The development and commercialisation of new pharmaceutical products is highly competitive and subject to rapid and significant technological advancements. We face competition from major multi-national pharmaceutical companies, biotechnology companies and speciality pharmaceutical companies. A number of large pharmaceutical and biotechnology companies currently market and sell products, or are developing drug candidates, for the treatment of cancer. Smaller or early-stage companies may also

prove to be significant competitors, particularly through collaborative arrangements with large, established companies. Potential competitors also include academic institutions, government agencies and other public and private research organisations.
Our competitors with development-stage programmes may obtain marketing approval from the FDA or other comparable regulatory authorities for their drug candidates more rapidly than we do, and they could establish a strong market position before we are able to enter the market. In addition, our competitors may succeed in developing, acquiring or licensing technologies and products that are more effective, more effectively marketed and sold or less costly than any drug candidates that we may develop, which could render our drug candidates non-competitive and obsolete and result in our competitors establishing a strong market position for either the product or a specific indication before we are able to enter the market.
Many of our competitors, either alone or with their strategic collaborators, have substantially greater financial, technical and human resources than we do. Accordingly, our competitors may be more successful than we are in obtaining approval for treatments and achieving widespread market acceptance, which may render our treatments obsolete or non-competitive. Mergers and acquisitions in the biotechnology and pharmaceutical industries may result in even more resources being concentrated among a smaller number of our competitors. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical studies, as well as in acquiring technologies complementary to, or necessary for, our programmes.
We are aware of several companies using various technologies, including AI and other sophisticated computational tools, to accelerate drug development and improve the quality of identified drug candidates. These companies include Relay Therapeutics, AbCellera, Schrodinger, Recursion Pharmaceuticals, PathAI, Insitro, Valo Health, Cellarity, XtalPi, BenevolentAI, Datavant and Atomwise.

We have invested, and expect to continue to invest, in research and development efforts that further enhance our technology platform. If the return on these investments is lower or develops more slowly than we expect, our revenue and results of operations may suffer.
We use our technological capabilities for the discovery of new drugs and, since our inception, we have invested, and expect to continue to invest, in research and development efforts that further enhance our technology platform. These investments may involve significant time, risks and uncertainties, including the risk that the expenses associated with these investments may affect our margins and results of operations and that such investments may not generate sufficient technological advantages relative to alternatives in the market, which would in turn, impact revenues generated to offset the liabilities assumed and expenses associated with these investments. The software industry changes rapidly as a result of technological and product developments, which may render our platform’s ability to identify and develop drug candidates less efficient than other technologies and platforms. We believe that we must continue to invest a significant amount of time and resources in our technology platform to maintain and improve our competitive position. If we do not achieve the benefits anticipated from these investments, if the achievement of these benefits is delayed or if our technology is not able to accelerate the process of drug discovery as quickly as we anticipate, our revenue and results of operations may be adversely affected.

We must adapt to rapid and significant technological change and respond to introductions of new products and technologies by competitors to remain competitive.
In addition to using our platform for the discovery and development of our own drug candidates, we provide our drug discovery solution and capabilities in industries that are characterised by significant enhancements and evolving industry standards. As a result, our and our collaborators’ needs are rapidly evolving. If we do not appropriately innovate and invest in new technologies, including within the field of AI, our platform may become less competitive, and our collaborators could move to new technologies offered by our competitors or engage in drug discovery themselves. We believe that because of the initial time investment required by many of our collaborators to reach a decision about whether to collaborate with us, it may be difficult to regain a commercial relationship with such collaborators should they enter into a partnership or collaboration agreement with a competitor. Without the timely introduction of new solutions and technological enhancements, our offerings will likely become less competitive over time, in which case our competitive position and results of operations could suffer. Accordingly, we focus significant efforts and resources on the development and identification of new technologies and markets to further broaden and deepen our capabilities and expertise in AI drug discovery and development. To the extent we fail to timely introduce new and innovative technologies or solutions, adequately predict our collaborators’ needs or fail to obtain desired levels of market acceptance, our business may suffer and our results of operations could be adversely affected.

Our adoption and deployment of AI and machine learning ("AI/ML") technologies in our drug discovery platform and processes may not be effective and may expose us to operational challenges, reputational harm and legal liability.
The industry in which we compete is characterized by rapid technological advancements, frequent introductions of new products and heavy competition. The discovery of new drugs and the achievement of new targets remain vital to our success, and the effective implementation of AI/ML technologies into our drug discovery platform is a critical element of our business that has the potential to provide significant benefits to our business.
As with many developing technologies, AI presents risks and challenges that could affect its further development, adoption, and use, and therefore our business especially as the use of AI/ML technologies becomes more important to our operations over time. Our AI algorithms may be flawed, or the datasets we use may be insufficient, of poor quality, or contain biased information, which may lead to flawed, biased, and inaccurate results. Further, our AI algorithms may rely in part on unknown third-party intellectual property rights, and the outputs we generate or seek may be infringing on those rights, which exposes us to potential legal risk. Inappropriate or controversial data practices by data scientists, engineers, and end-users of our systems could impair the acceptance of AI solutions. These deficiencies could undermine the decisions, predictions, or analysis that AI applications produce, subjecting us to legal liability, and brand or reputational harm. Emerging ethical issues surround the use of AI/ML technologies, and we may be subject to reputational and legal risk if we enable or offer AI-based technologies that are controversial because of their impact on healthcare access, privacy, or other social issues.
We face increased competition from other companies that are using AI/ML technologies and related methods for drug discovery, some of which have more resources than we do and may have developed more effective methods than we have, which may reduce our effectiveness in identifying potential targets and attracting collaborators to work with us. Even with the successful implementation of AI/ML technologies, we may fail to correctly identify indications and allocate R&D resources efficiently,
which could adversely impact our pipeline and ability to compete effectively.

AI/ML technologies are relatively new and the business, legal and ethical landscape regarding their use, commercialization and regulation is unsettled and constantly evolving. Uncertainty in the legal regulatory regime relating to AI/ML technologies may require significant resources to modify and maintain business practices to comply with new or rapidly changing U.S. and non-U.S. laws and regulations. Several jurisdictions around the globe, including the U.K., the E.U. and certain U.S. states have proposed, enacted or are considering laws governing the development and use of AI/ML. In the U.K., the government has published a white paper calling for existing regulators to implement certain specific principles to guide and inform the responsible development and use of AI/ML. In the E.U., regulators have reached political agreement on the text of the Artificial Intelligence Act, which, when adopted and in force, will have a direct effect across all E.U. jurisdictions and could impose onerous obligations related to the use of AI-related systems. Other jurisdictions may decide to adopt similar or more restrictive legislation that may render the use of such technologies challenging.

We rely upon third-party providers of cloud-based infrastructure to host our software solutions. Any disruption in the operations of these third-party providers, limitations on capacity or interference with our use could adversely affect our business, financial condition, results of operations and prospects.
We outsource substantially all of the infrastructure relating to our hosted software solutions to third-party hosting services. Customers of our hosted software solutions need to be able to access our computational platform at any time, without interruption or degradation of performance, and we provide them with service-level commitments with respect to uptime. Our hosted software solutions depend on protecting the virtual cloud infrastructure hosted by third-party hosting services by maintaining its configuration, architecture, features and interconnection specifications, as well as the information stored in these virtual data centres, which is transmitted by third-party internet service providers. Any limitation on the capacity of our third-party hosting services could impede our ability to onboard new customers or expand the usage of our existing customers, which could adversely affect our business, financial condition and results of operations. In addition, any incident affecting our third-party hosting services’ infrastructure that may be caused by cyber-attacks, natural disasters, climate change, fires, floods, severe storms, earthquakes, power loss, telecommunications failures, terrorist or other attacks and other similar events beyond our control could negatively affect our cloud-based solutions. A prolonged service disruption affecting our cloud-based solutions for any of the foregoing reasons would negatively impact our ability to serve our customers and could damage our reputation with current and potential customers, expose us to liability, cause us to lose customers or otherwise harm our business. We may also incur significant costs for using alternative equipment or taking other actions in preparation for, or in reaction to, events that damage the third-party hosting services we use.
In the event that our service agreements with our third-party hosting services are terminated, or there is a lapse of service, elimination of services or features that we utilise, interruption of internet service provider connectivity or damage to such facilities, we could experience interruptions in access to our platform as well as significant delays and additional expense in arranging or creating new facilities and services and/or re-architecting our hosted software solutions for deployment on a different cloud infrastructure service provider, which could adversely affect our business, financial condition and results of operations.

Defects or disruptions in our technology platform could result in diminishing demand for the drug candidates discovered using such platforms and a reduction in our revenues, and subject us to substantial liability.
Our ability to effectively deploy our drug discovery platform depends upon the continuous, effective and reliable operation of our software and related tools and functions. Our technology platform is inherently complex and may contain defects or errors. The risk of errors is particularly significant when a new software application is first introduced or when new versions or enhancements of existing software applications are used in our technology platform. We have from time to time found defects in our software, and new errors in our existing software may be detected in the future. Any errors, defects, disruptions or other performance problems with our technology platform could adversely impact the efficacy of our drug discovery processes, delay our drug discovery and collaboration timelines, hurt our reputation or damage our collaborators’ businesses. If any of these events occurs, our collaborators may delay or withhold payment to us, cancel their agreements with us, elect not to renew, make service credit claims, warranty claims or other claims against us, and we could lose future revenues. The occurrence of any of these events could result in diminishing demand for our technology platform and any drug candidates discovered through such a platform, a reduction of our revenues and increased expenses of litigation or substantial liability.

The market opportunities for our drug candidates may be smaller than we anticipate or may be limited to those patients who are ineligible for or have failed prior treatments, and our estimates of the prevalence of our target patient populations may be inaccurate.
Our current and future target patient populations are based on our beliefs and estimates regarding the incidence or prevalence of certain types of cancers that may be addressable by our drug candidates, which is derived from a variety of sources, including scientific literature and surveys of clinics. Our projections may prove to be incorrect and the number of potential patients may turn out to be lower than expected. Even if we obtain significant market share for our drug candidates, because the potential target populations could be small, we may never achieve profitability without obtaining regulatory approval for additional indications, including use of our drug candidates for first-line and second-line therapy.
Cancer therapies are sometimes characterised by line of therapy (first-line, second-line, third-line, etc.), and the FDA often approves new therapies initially only for a particular line or lines of use. When cancer is detected early enough, first-line therapy is sometimes adequate to cure the cancer or prolong life without a cure. Whenever first-line therapy, usually chemotherapy, antibody drugs, tumour-targeted small molecules, hormone therapy, radiation therapy, surgery or a combination of these, proves unsuccessful, second-line therapy may be administered. Second-line therapies often consist of more chemotherapy, radiation, antibody drugs, tumour-targeted small molecules or a combination of these. Third-line therapies can include chemotherapy, antibody drugs and small molecule tumour-targeted therapies, more invasive forms of surgery and new technologies. We expect to initially seek approval of some of our drug candidates as second- or third-line therapies for patients who have failed other approved treatments. Subsequently, for those drug candidates that prove to be sufficiently beneficial, if any, we would expect to seek approval as a second-line therapy and potentially as a first-line therapy, but there is no guarantee that our drug candidates, even if approved for third-line therapy, would be approved for second-line or first-line therapy. In addition, we may have to conduct additional clinical trials prior to gaining approval for any of our current or future drug candidates as potential second-line or first-line therapies.

Even if we obtain regulatory approval of our current or future drug candidates, the products may not gain market acceptance among physicians, patients, hospitals, cancer treatment centres and others in the medical community.
The use of artificial intelligence, machine learning and other technology-based platforms to discover compounds and molecules and develop optimally-designed drug candidates is still a recent phenomenon; and therefore, the drug candidates resulting from such a process may not become broadly accepted by physicians, patients, hospitals and others in the medical community, even if approved by the appropriate regulatory authorities for marketing and sale. If we obtain regulatory approval for any of our current programmes or any future drug candidates and such drug candidates do not gain an adequate level of market acceptance, we could be prevented from or significantly delayed in achieving profitability. Various factors will influence whether our drug candidates, if approved, are accepted in the market, including:
the efficacy of our drug candidates as demonstrated in clinical trials, and, if required by any applicable authority in connection with the approval for the applicable indications, the ability of our drug candidates to provide patients with incremental health benefits, as compared with other available therapies;
potential product liability claims;
physicians, hospitals and patients considering our drug candidates as safe and effective treatment options;
the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;
the prevalence and severity of any side effects of our drug candidates;
product labelling or product insert requirements of the FDA or other non-U.S. regulatory authorities;
limitations or warnings contained in the labelling approved by the FDA or other non-U.S. regulatory authorities;
the cost of treatment in relation to current and future treatment alternatives;
pricing of our products and the availability of coverage and adequate reimbursement from third-party payors and government authorities;
the willingness of patients to pay out-of-pocket in the absence of coverage by third-party payors and government authorities;
relative convenience and ease of administration, including as compared to current and future alternative treatments and competitive therapies; and
the effectiveness of our sales and marketing efforts.
Even if our drug candidates, if approved, achieve market acceptance, we may not be able to maintain that market acceptance over time if new products or technologies are introduced that are more favourably received than our products, are more cost effective or render our products obsolete.

The effects of health epidemics in regions where we, or the third parties on which we rely, have business operations could adversely impact our business, including our preclinical studies and clinical trials, as well as the business or operations of our CROs or other third parties with whom we conduct business.
Our business could be adversely affected by health epidemics in regions where we have concentrations of clinical trial sites or other business operations, and could cause significant disruption in the operations of third-party manufacturers and CROs upon whom we rely.
Quarantines, shelter-in-place and similar government orders, or the perception that such orders, shutdowns, or other restrictions on the conduct of business operations could occur, whether related to new variants of COVID-19 or other infectious diseases, could impact personnel at third-party manufacturing facilities in the United Kingdom and other countries, or the availability or cost of materials, which would disrupt our supply chain. In addition, our business operations, preclinical studies and clinical trials may be
30

affected by another pandemic, including delays or difficulties in enrolling, treating and retaining patients in our clinical trials.

We have in the past and may in the future acquire other companies or technologies, which could divert our management’s attention, result in additional dilution to our shareholders and otherwise disrupt our operations and adversely affect our operating results.
In August 2021, we acquired 100% of the outstanding share capital of Allcyte GmbH, or Allcyte, a precision medicine biotechnology company. Following the acquisition, Allcyte was merged with the Group’s 100% owned subsidiary, Alphaexscientia Beteiligungs GmbH, and the merged entity was renamed as Exscientia GmbH. We may in the future seek to acquire or invest in additional businesses, solutions or technologies that we believe could complement or expand our solutions, enhance our technical capabilities or otherwise offer growth opportunities. The pursuit of potential acquisitions may divert the attention of management and cause us to incur various expenses in identifying, investigating and pursuing suitable acquisitions, whether or not they are consummated.
We have limited experience in acquiring new businesses. If we acquire additional businesses in the future, we will face all of these challenges again. We cannot assure you that following any acquisition we will achieve the expected synergies to justify the transaction, due to a number of factors, including:
inability to integrate or benefit from acquired technologies or services in a profitable manner;
incurrence of acquisition-related costs;
unanticipated costs or liabilities associated with the acquisition;
difficulty integrating the accounting systems, operations and personnel of the acquired business;
difficulties and additional expenses associated with supporting legacy products and hosting infrastructure of the acquired business;
difficulty converting the customers of the acquired business onto our solutions and contract terms, including disparities in the revenues, licensing, support or professional services model of the acquired company;
diversion of management’s attention from other business concerns;
adverse effects to our existing business relationships with business partners and customers as a result of the acquisition;
the potential loss of key employees;
use of resources that are needed in other parts of our business; and
use of substantial portions of our available cash to consummate the acquisition.
In addition, a significant portion of the purchase price of companies we acquire may be allocated to acquired goodwill and other intangible assets, which must be assessed for impairment at least annually. In the future, if our acquisitions do not yield expected returns, we may be required to take charges to our operating results based on this impairment assessment process, which could adversely affect our results of operations.
Acquisitions could also result in dilutive issuances of equity securities or the incurrence of debt, which could adversely affect our operating results. In addition, if an acquired business fails to meet our expectations, our business, financial condition, results of operations and prospects may suffer.

Table of Contents
Clinical trial and product liability lawsuits against us could divert our resources, cause us to incur substantial liabilities and limit commercialisation of our drug candidates.
We face an inherent risk of clinical trial and product liability exposure related to the testing of drug candidates in clinical trials, and we will face an even greater risk if we commercially sell any products that we may develop. While we currently have no products that have been approved for commercial sale, the current and future use of drug candidates by us in clinical trials, and the sale of any approved products in the future, may expose us to liability claims. These claims might be made by patients who use the product, healthcare providers, pharmaceutical companies or others selling such products. If we cannot successfully defend ourselves against claims that our drug candidates or products caused injuries, we will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:
decreased demand for our drug candidates, if approved;
injury to our reputation and significant negative media attention;
withdrawal of clinical trial participants;
significant costs to defend any related litigation;
substantial monetary awards to trial participants or patients;
loss of revenue;
reduced resources of our management to pursue our business strategy; and
the inability to commercialise our drug candidates.
We will need to increase our insurance coverage as we expand our clinical trials or if we commence commercialisation of any drug candidates. If a successful clinical trial or product liability claim or series of claims is brought against us for uninsured liabilities or in excess of insured liabilities, our assets may not be sufficient to cover such claims and our business operations could be impaired.

Our insurance policies are expensive and protect us only from some business risks, which leaves us exposed to significant uninsured liabilities.
We do not carry insurance for all categories of risk that our business may encounter and our policies have limits and significant deductibles. Some of the policies we currently maintain include clinical trial, product liability, general liability, property, employment and director and officer insurance.
Our existing insurance coverage and any additional coverage we acquire in the future may not be sufficient to reimburse us for expenses or losses we may suffer. Moreover, insurance coverage is becoming increasingly expensive, and we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses. Any significant uninsured liability may require us to pay substantial amounts, and a successful liability claim or series of claims in which judgements exceed our insurance coverage could adversely affect our business, financial condition, results of operations and prospects.

Risks Related to Collaborators and Other Third Parties
Our drug discovery collaborators have significant discretion regarding the clinical development of the programmes subject to the collaboration. The failure of our collaborators to perform their obligations under our collaboration agreements could negatively impact our business. We may never realise the return on our investment of resources in our drug discovery collaborations.
We use our technology platform to engage in drug discovery with collaborators who are engaged in drug discovery and development. These collaborators include pre-commercial biotechnology companies and large-scale pharmaceutical companies. When we engage in drug discovery with these collaborators, we enter into agreements that provide us the right to receive option fees, cash milestone payments upon the achievement of specified development, regulatory and commercial sales milestones for the drug discovery targets and potential royalties. From time to time, we may take equity stakes in our drug discovery collaborators.
Our drug discovery collaborations may not lead to development or commercialisation of drug candidates that result in our receipt of such option fees, milestone payments or royalties in a timely manner, or at all. Our drug discovery collaborators may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialisation of any drug candidates. In addition, our ability to realise return from our drug discovery collaborations is subject to the following risks:
drug discovery collaborators have significant discretion in determining the amount and timing of efforts and resources that they will apply to our collaborations and may not perform their obligations as expected;
drug discovery collaborators may not pursue development or commercialisation of any drug candidates for which we are entitled to option fees, milestone payments or royalties or may elect not to continue or renew development or commercialisation programmes based on results of clinical trials or other studies, changes in the collaborator’s strategic focus or available funding, or external factors, such as an acquisition, that divert resources or create competing priorities;
drug discovery collaborators may delay clinical trials for which we are entitled to milestone payments;
drug discovery collaborators have significant discretion in determining when to make announcements about the status of our collaborations, including about preclinical and clinical developments and timelines for advancing the collaborative programmes;
we may not have access to, or may be restricted from disclosing, certain information regarding our collaborators’ drug candidates being developed or commercialised and, consequently, may have limited ability to inform our shareholders and ADS holders about the status of, and likelihood of achieving, milestone payments or royalties under such collaborations;
drug discovery collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with any drug candidates and products for which we are entitled to milestone payments or royalties if the collaborator believes that the competitive products are more likely to be developed or can be commercialised under terms that are more economically attractive;
drug candidates discovered in drug discovery collaborations with us may be viewed by our collaborators as competitive with their own drug candidates or products, which may cause our collaborators to cease to devote resources to the commercialisation of any such drug candidates;
existing drug discovery collaborators and potential future drug discovery collaborators may begin to perceive us to be a competitor more generally, particularly as we advance our internal drug discovery programmes, and therefore may be unwilling to continue existing collaborations with us or to enter into new collaborations with us;
drug discovery collaborators may fail to comply with applicable regulatory requirements regarding the development, manufacture, distribution or marketing of a drug candidate or product, which may impact our ability to receive milestone payments;
33

Table of Contents
disagreements with drug discovery collaborators, including disagreements over intellectual property or proprietary rights, contract interpretation or the preferred course of development, might cause delays or terminations of the research, development or commercialisation of drug candidates for which we are eligible to receive milestone payments, or might result in litigation or arbitration;
drug discovery collaborators may not properly obtain, maintain, enforce, defend or protect our intellectual property or proprietary rights or may use our proprietary information in such a way as to potentially lead to disputes or legal proceedings that could jeopardise or invalidate our or their intellectual property or proprietary information or expose us and them to potential litigation;
drug discovery collaborators may infringe, misappropriate or otherwise violate the intellectual property or proprietary rights of third parties, which may expose us to litigation and potential liability; and
drug discovery collaborations may be terminated prior to our receipt of any significant value from the collaboration.
If any drug discovery collaborations that we enter into do not result in the successful development and commercialisation of drug products that result in option fees, milestone payments, or royalties to us, we may not realise satisfactory, if any, returns on the resources we have invested in the drug discovery collaboration. Moreover, even if a drug discovery collaboration initially leads to the achievement of milestones that result in payments to us, it may not continue to do so.
If we are not able to establish or maintain partnerships to develop and commercialise any of the drug candidates we discover internally, we may have to alter our development and commercialisation plans for those drug candidates and our business could be adversely affected.
We have worked closely with our partners, such as Bristol Myers Squibb Company, or BMY, to develop and advance drug discovery programmes past the discovery stage and into preclinical studies or human clinical trials. We expect to rely on future collaborators for the development and potential commercialisation of drug candidates we discover internally when we believe it will help maximise the commercial value of the drug candidate. We face significant competition in seeking appropriate collaborators for these activities, and a number of more established companies may also be pursuing development and commercialisation for the same or similar drug candidates. These established companies may have a competitive advantage over us due to their size, financial resources and greater clinical development and commercialisation expertise. Furthermore, collaborations are complex and time-consuming to negotiate and document. Whether we reach a definitive agreement for such collaborations will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. Those factors may include the design or results of preclinical studies and clinical trials, the likelihood of approval by the FDA or similar regulatory authorities outside the United States, the potential market for the subject drug candidate, the costs and complexities of manufacturing and delivering such drug candidate to patients, the potential of competing products, the existence of uncertainty with respect to our ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the challenge, and industry and market conditions generally. The collaborator may also consider alternative drug candidates or technologies for similar indications that may be available to collaborate on and whether such a collaboration could be more attractive than the one with us for our drug candidate.
If we are unable to reach agreements with suitable collaborators on a timely basis, on acceptable terms or at all, we may have to curtail the development of a drug candidate, reduce or delay its development programme or one or more of our other development programmes or increase our expenditures and undertake development or commercialisation activities at our own expense. If we elect to fund and undertake development or commercialisation activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to us on acceptable terms or at all. If we fail
34

Table of Contents
to enter into collaborations and do not have sufficient funds or expertise to undertake the necessary development and commercialisation activities, we may not be able to further develop any drug candidates or bring them to market.

In recent periods, we have depended on a limited number of collaborators for our revenue, the loss of any of which could have an adverse impact on our business.
In recent periods, a limited number of collaborations accounted for a significant portion of our revenues. For the year ended December 31, 2023, one of our partners accounted for 72% of our revenue, with another accounting for a further 25%. These collaborations cover a large number of programmes under contract, and therefore represent a large portion of potential downstream value. As a result, if we fail to maintain our relationships with our collaborators or if any of our collaborators discontinue their programmes, our future results of operations could be materially and adversely affected.

We may never realise a return on our equity investments in our drug discovery collaborators.
We have decided to take and may decide in the future to take equity stakes in our drug discovery collaborators. We may never realise a return on our equity investments in our drug discovery collaborators. None of the drug discovery collaborators in which we hold equity generate revenue from commercial sales of drug products. They are therefore dependent on the availability of capital on favourable terms to continue their operations. In addition, if the drug discovery collaborators in which we hold equity raise additional capital, our ownership interest in and degree of control over these drug discovery collaborators will be diluted, unless we have sufficient resources and choose to invest in them further or successfully negotiate contractual anti-dilution protections for our equity investment. The financial success of our equity investment in any collaborator will likely be dependent on a liquidity event, such as a public offering, acquisition or other favourable market event reflecting appreciation in the value of the equity we hold. The capital markets for public offerings and acquisitions are dynamic, and the likelihood of liquidity events for the companies in which we hold equity interests could significantly worsen. Further, valuations of privately held companies are inherently complex due to the lack of readily available market data. If we determine that any of our investments in such companies have experienced a decline in value, we may be required to record an impairment, which could negatively impact our financial results. All of the equity we hold in our drug discovery collaborators is subject to a risk of partial or total loss of our investment.

We contract with third parties for the manufacture of our drug candidates for preclinical development and clinical testing, and expect to continue to do so for commercialisation. This reliance on third parties increases the risk that we will not have sufficient quantities of our drug candidates or products or such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialisation efforts.
We do not currently own or operate, nor do we have any plans to establish in the future, any manufacturing facilities or personnel. We rely, and expect to continue to rely, on third parties for the manufacture of our drug candidates for preclinical development and clinical testing, as well as for the commercial manufacture of our products if any of our drug candidates receive marketing approval. This reliance on third parties increases the risk that we will have less direct control over the conduct, timing and completion of such manufacturing and thus, will not have sufficient quantities of our drug candidates or products or such quantities at an acceptable cost or quality, which could delay, prevent or impair our development or commercialisation efforts.

Table of Contents
The facilities used by our contract manufacturers to manufacture our drug candidates must be inspected by the FDA and non-U.S. regulatory authorities pursuant to pre-approval inspections that will be conducted after we submit our marketing applications to the FDA and non-U.S. regulatory authorities. We have limited control over the manufacturing process of, and will depend on, our contract manufacturers for compliance with cGMPs, with which they are required to comply, in connection with the manufacture of our drug candidates. If our contract manufacturers cannot successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or other non-U.S. regulatory authorities, they will not be able to pass regulatory inspections and/or maintain regulatory compliance for their manufacturing facilities. In addition, we have limited control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance and qualified personnel. If the FDA or a comparable foreign regulatory authority finds deficiencies with or does not approve these facilities for the manufacture of our drug candidates or if it finds deficiencies or withdraws any such approval in the future, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain regulatory approval for or market our drug candidates, if approved. We, or our contract manufacturers, any future collaborators and their contract manufacturers could be subject to periodic unannounced inspections by the FDA or other non-U.S. authorities, to monitor and ensure compliance with cGMP. Despite our efforts to audit and verify regulatory compliance, one or more of our third-party manufacturing vendors may be found on regulatory inspection by the FDA or other non-U.S. authorities to be noncompliant with cGMP regulations. Our failure, or the failure of our third party manufacturers, to comply with applicable regulations could result in sanctions being imposed on us, including shutdown of the third-party vendor or invalidation of drug product lots or processes, warning or untitled letters, clinical holds, fines, injunctions, civil penalties, delays, suspension, variation or withdrawal of requisite approvals (including marketing approvals), licence revocation, seizures or recalls of drug candidates or products, if approved, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect our business and supplies of our drug candidates, if approved.
We may be unable to establish any agreements with third-party manufacturers or to do so on acceptable terms. Even if we are able to establish agreements with third-party manufacturers, reliance on third-party manufacturers entails additional risks to those discussed above, including:
reliance on the third party for regulatory compliance and quality assurance;
the possible breach of the manufacturing agreement by the third party;
damage to our brand reputation caused by defective products or drug candidates produced by the third party;
the possible misappropriation of our proprietary information, including our trade secrets and know-how; and
the possible termination or non-renewal of the agreement by the third party at a time that is costly or inconvenient for us.
Our drug candidates and any products that we may develop may compete with other drug candidates and approved products for access to manufacturing facilities. There is a limited number of manufacturers that operate under cGMP regulations and that might be capable of manufacturing for us. These third-party manufacturers may also have relationships with other commercial entities, including our competitors, for whom they may also be manufacturing certain products and/or drug candidates, which could affect their performance on our behalf.
Any performance failure on the part of our existing or future manufacturers could delay clinical development or marketing approval. If our current contract manufacturers cannot perform as agreed, we may be required to replace such manufacturers, which may cause us to incur additional costs and undergo further delays in identifying and qualifying any such replacement. There is a natural transition period when a new third party commences work, which may cause delays that materially impact our ability to
36

Table of Contents
meet the anticipated timelines for manufacturing our products and drug candidates. In addition, changes in manufacturers often involve changes in manufacturing procedures and processes, which could require that we conduct bridging studies between our prior clinical supply used in our clinical trials and that of any new manufacturer. We may be unsuccessful in demonstrating the comparability of clinical supplies which could require the conduct of additional clinical trials.
Given our current and anticipated future dependence upon others for the manufacture of our drug candidates or products, if these third parties do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols or regulatory requirements or for other reasons, our financial results and the commercial prospects for our drug candidates would be harmed, our costs could increase and our ability to generate revenue could be delayed.

We rely on third parties to conduct our clinical trials of GTAEXS617 and expect to rely on third parties to conduct future clinical trials. If these third parties do not carry out their contractual duties, comply with regulatory requirements or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialise our drug candidates and our business could be substantially harmed.
We do not have the ability to independently conduct clinical trials. We rely, and expect to continue to rely, on medical institutions, clinical investigators, contract laboratories, collaborators and other third parties, such as CROs, to assist in the conduct of clinical trials for our drug candidates, including our clinical trials of GTAEXS617. We may also rely on academic and private non-academic institutions to conduct and sponsor clinical trials relating to our drug candidates. We will not control the design or conduct of the investigator-sponsored trials, and it is possible that the FDA or non-U.S. regulatory authorities will not view these investigator-sponsored trials as providing adequate support for future clinical trials, whether controlled by us or third parties, for any one or more reasons, including elements of the design or execution of the trials or safety concerns or other trial results.
Such third-party arrangements will likely provide us certain information rights with respect to the investigator-sponsored trials, including access to and the ability to use and reference the data, including for our own regulatory filings, resulting from the investigator-sponsored trials. However, we would not have control over the timing and reporting of the data from investigator-sponsored trials, nor would we own the data from the investigator-sponsored trials. If we are unable to confirm or replicate the results from the investigator-sponsored trials or if negative results are obtained, we would likely be further delayed or prevented from advancing further clinical development of our drug candidates. Further, if investigators or institutions breach their obligations with respect to the clinical development of our drug candidates, or if the data prove to be inadequate compared to the first-hand knowledge we might have gained had the investigator-sponsored trials been sponsored and conducted by us, then our ability to design and conduct any future clinical trials ourselves may be adversely affected.
Though we rely, and expect to continue to rely, heavily on third parties for execution of clinical trials for our drug candidates and as such, control only certain aspects of their activities, we still remain responsible for ensuring that each of our clinical trials is conducted in accordance with the applicable protocol, legal and regulatory requirements and scientific standards and our reliance on CROs will not relieve us of our regulatory responsibilities. For any violations of laws and regulations during the conduct of our clinical trials, we could be subject to warning letters or enforcement action that may include civil penalties up to and including criminal prosecution.

Table of Contents
We, our principal investigators and our CROs are required to comply with regulations, including GCPs, for conducting, monitoring, recording and reporting the results of clinical trials to ensure that the data and results are scientifically credible and accurate, and that the trial patients are adequately informed of the potential risks of participating in clinical trials and their rights are protected. These regulations are enforced by the FDA, the Competent Authorities of the European Economic Area, or EEA countries, and comparable non-U.S. regulatory authorities for any products in clinical development. The FDA and non-U.S. regulatory authorities enforce GCP regulations through periodic inspections of clinical trial sponsors, principal investigators and trial sites. If we, our principal investigators or our CROs fail to comply with applicable GCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or comparable non-U.S. regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We cannot assure you that, upon inspection, the FDA or non-U.S. regulatory authorities will determine that any of our future clinical trials will comply with GCPs. In addition, our clinical trials must be conducted with drug candidates produced under cGMP regulations. Our failure or the failure of our principal investigators or CROs to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process and could also subject us to enforcement action. In the United States, we also are required to register ongoing clinical trials and post the results of completed clinical trials on a government-sponsored database, ClinicalTrials.gov, within certain timeframes. Comparable registration and transparency requirements may apply outside of the United States. Failure to do so can result in fines, adverse publicity and civil and criminal sanctions.
Although we designed our Phase 1/2 clinical trial of GTAEXS617 and intend to design the future clinical trials for our other drug candidates, we expect that CROs will assist in the conduct all of our clinical trials. As a result,we may have limited direct control over many important aspects of our development programmes, including their conduct and timing. Our reliance on third parties to conduct future clinical trials also results in less direct control over the management of data developed through clinical trials than would be the case if we were relying entirely upon our own staff. Communicating with outside parties can also be challenging, potentially leading to mistakes as well as difficulties in coordinating activities. Outside parties may:
have staffing difficulties;
fail to comply with contractual obligations;
experience regulatory compliance issues;
undergo changes in priorities or become financially distressed; or
form relationships with entities, some of which may be our competitors.
These factors may materially adversely affect the willingness or ability of third parties to conduct our clinical trials and may subject us to unexpected cost increases that are beyond our control. If the principal investigators or CROs do not perform clinical trials in a satisfactory manner, breach their obligations to us or fail to comply with regulatory requirements, the development, regulatory approval and commercialisation of our drug candidates may be delayed, we may not be able to obtain regulatory approval and commercialise our drug candidates or our development programme may be materially and irreversibly harmed. If we are unable to rely on clinical data collected by our principal investigators or CROs, we could be required to repeat, extend the duration of or increase the size of any clinical trials we conduct and this could significantly delay commercialisation and require significantly greater expenditures.
If any of our relationships with these third-party principal investigators or CROs terminate, we may not be able to enter into arrangements with alternative investigators or CROs. If principal investigators or CROs do not carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols, regulatory requirements or for other reasons, any clinical trials such

Table of Contents
principal investigators or CROs are associated with may be extended, delayed or terminated, and we may not be able to obtain regulatory approval for or successfully commercialise our drug candidates. As a result, we believe that our financial results and the commercial prospects for our drug candidates in the subject indication would be harmed, our costs could increase and our ability to generate revenue could be delayed.

The third parties upon whom we rely for the supply of the active pharmaceutical ingredients used in our drug candidates are our sole source of supply, and the loss of any of these suppliers could harm our business.
The active pharmaceutical ingredients, or APIs, used in our drug candidates are mostly supplied to us from single-source suppliers. Our ability to successfully develop our drug candidates, and to ultimately supply our commercial products in quantities sufficient to meet the market demand, depends in part on our ability to obtain the API for these products in accordance with regulatory requirements and in sufficient quantities for clinical testing and commercialisation. We do not currently have arrangements in place for a redundant or second-source supply of any such API in the event any of our current suppliers of such API cease their operations for any reason. We are also unable to predict how changing global economic conditions or potential global health concerns will affect our third-party suppliers and manufacturers. Any negative impact of such matters on our third-party suppliers and manufacturers may also have an adverse impact on our results of operations or financial condition.
For all of our drug candidates, we intend to identify and qualify additional manufacturers to provide such API prior to submission of a new drug application, or NDA, to the FDA and/or a marketing authorisation application, or MAA, to the EMA. We are not certain, however, that our single-source suppliers will be able to meet our demand for their products, either because of the nature of our agreements with those suppliers, our limited experience with those suppliers or our relative importance as a customer to those suppliers. It may be difficult for us to assess their ability to timely meet our demand in the future based on past performance. While our suppliers have generally met our demand for their products on a timely basis in the past, they may subordinate our needs in the future to their other customers.
Establishing additional or replacement suppliers for the API used in our drug candidates, if required, may not be accomplished quickly. If we are able to find a replacement supplier, such replacement supplier would need to be qualified and may require additional regulatory inspection or approval, which could result in further delay. While we seek to maintain adequate inventory of the API used in our drug candidates, any interruption or delay in the supply of components or materials, or our inability to obtain such API from alternate sources at acceptable prices in a timely manner could impede, delay, limit or prevent our development efforts, which could harm our business, results of operations, financial condition and prospects.

We rely on CROs to synthesise any molecules with therapeutic potential that we discover. If such organisations do not meet our supply requirements, development of any drug candidate may be delayed.
We currently rely and expect to continue to rely on third parties to synthesise any molecules with therapeutic potential that we discover. Reliance on third parties may expose us to different risks than if we were to synthesise molecules ourselves. If these third parties do not successfully carry out their contractual duties, meet expected deadlines or synthesise molecules in accordance with regulatory requirements, if there are disagreements between us and such parties or if such parties are unable to expand capacities, we may not be able to fulfil, or may be delayed in producing sufficient drug candidates to meet, our supply requirements due to environmental or other factors such as climate change. These
39

facilities may also be affected by natural disasters (whether caused by climate change or otherwise), such as floods or fire, or geopolitical developments, or such facilities could face production issues, such as contamination or regulatory concerns following a regulatory inspection of such a facility. In such instances, we may need to locate an appropriate replacement third-party facility and establish a contractual relationship, which may not be readily available or on acceptable terms, which would cause additional delay and increased expense, and may have a material adverse effect on our business.
We or any third party may also encounter shortages in the raw materials or API necessary to synthesise any molecule we may discover in the quantities needed for preclinical studies or clinical trials, as a result of capacity constraints or delays or disruptions in the market for the raw materials or API. Even if raw materials or API are available, we may be unable to obtain sufficient quantities at an acceptable cost or quality. The failure by us or the third parties to obtain the raw materials or API necessary to synthesise sufficient quantities of any molecule we may discover could delay, prevent or impair our development efforts and may have a material adverse effect on our business.


Risks Related to Intellectual Property
If we fail to comply with our obligations under our existing intellectual property licence agreements or under any future intellectual property licences, or otherwise experience disruptions to our business relationships with our current or any future licensors, we could lose intellectual property rights that are important to our business.
We are party to a number of licence agreements pursuant to which we have been granted exclusive and non-exclusive worldwide licences to certain patents, software code and software programmes to, among other things, reproduce, use, execute, copy, operate, sublicence and distribute the licenced technology in connection with the marketing and sale of our software solutions and to develop improvements thereto. Our current licence agreements impose, and we expect that future licences will impose, specified royalty and other obligations on us.
In spite of our best efforts, our current or any future licensors might conclude that we have materially breached our licence agreements with them and might therefore terminate the licence agreements, thereby delaying our ability to market and sell our existing software solutions and develop and commercialise new software solutions that utilise technology covered by these licence agreements. If these in-licences are terminated, or if the underlying intellectual property fails to provide the intended exclusivity, competitors could market products and technologies similar to ours. This could have a material adverse effect on our competitive position, business, financial condition, results of operations and prospects.
Disputes may arise regarding intellectual property subject to a licensing agreement, including with respect to:
the scope of rights granted under the licence agreement and other interpretation-related issues;
the extent to which our technology and processes infringe on intellectual property of the licensor that is not subject to the licensing agreement;
the sublicensing of patent and other rights under any collaborative development relationships;
the inventorship and ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our current or future licensors and us and our collaborators; and
the priority of invention of patented technology.

40

Table of Contents
In addition, licence agreements are complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology, or increase what we believe to be our financial or other obligations under the relevant agreement. For example, our counterparties have in the past and may in the future dispute the amounts owed to them pursuant to payment obligations. If disputes over intellectual property that we have licenced prevent or impair our ability to maintain our current licensing arrangements on commercially acceptable terms, we may experience delays in the development and commercialisation of new software solutions and in our ability to market and sell existing software solutions, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our obligations under our existing or future drug discovery collaboration agreements may limit intellectual property rights that are important to our business. Further, if we fail to comply with our obligations under our existing or future collaboration agreements, or otherwise experience disruptions to our business relationships with our prior, current, or future collaborators, we could lose intellectual property rights that are important to our business.
We are party to collaboration agreements with biopharmaceutical companies, pursuant to which we provide drug discovery services but have no ownership rights, or only co-ownership rights, to certain intellectual property generated through the collaborations. We may enter into additional collaboration agreements in the future, pursuant to which we may have no ownership rights, or only co-ownership rights, to certain intellectual property generated through the future collaborations. If we are unable to obtain ownership or licence of such intellectual property generated through our prior, current or future collaborations and overlapping with, or related to, our own proprietary technology or drug candidates, then our business, financial condition, results of operations and prospects could be materially harmed.
Our existing collaboration agreements contain certain exclusivity obligations that require us to design compounds exclusively for our collaborators with respect to certain specific targets over a specified time period. Our future collaboration agreements may grant similar exclusivity rights to future collaborators with respect to target(s) that are the subject of such collaborations. These existing or future collaboration agreements may impose diligence obligations on us. For example, existing or future collaboration agreements may impose restrictions on us from pursuing the drug development targets for ourselves or for our other current or future collaborators, thereby removing our ability to develop and commercialise, or to jointly develop and commercialise with other current or future collaborators, drug candidates and technology related to the drug development targets. In spite of our best efforts, our prior, current or future collaborators might conclude that we have materially breached our collaboration agreements. If these collaboration agreements are terminated, or if the underlying intellectual property, to the extent we have ownership or licence thereof, fails to provide the intended exclusivity, competitors would have the freedom to seek regulatory approval of, and to market, products and technology identical to ours. This could have a material adverse effect on our competitive position, business, financial condition, results of operations and prospects.
Disputes may arise regarding intellectual property subject to a collaboration agreement, including:
the scope of ownership or licence granted under the collaboration agreement and other interpretation related issues;
the extent to which our technology and drug candidates infringe on intellectual property that is or will be generated through the collaboration, to which we do not have ownership or licence under such collaboration agreement;
the assignment or sublicence of intellectual property rights and other rights under the collaboration agreement;
41

Table of Contents
our diligence obligations under the collaboration agreement and what activities satisfy those diligence obligations; and
the inventorship and ownership of inventions and know-how resulting from the joint creation or use of intellectual property by us and our current or future collaborators.
In addition, collaboration agreements are complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property, or increase what we believe to be our obligations under the relevant agreements, either of which could have a material adverse effect on our business, financial condition, results of operations and prospects. Moreover, if disputes over intellectual property that we have owned, co-owned or in-licenced under the collaboration agreements prevent or impair our ability to maintain our current collaboration arrangements on commercially acceptable terms, we may be unable to successfully develop and commercialise the affected technology or drug candidates, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

If we are unable to obtain, maintain, enforce and protect patent protection for our technology and drug candidates or if the scope of the patent protection obtained is not sufficiently broad, our competitors could develop and commercialise technology and products similar or identical to ours, and our ability to successfully develop and commercialise our technology and drug candidates may be adversely affected.
Our success depends in large part on our ability to obtain and maintain protection of the intellectual property we may own solely and jointly with others or may licence from others, particularly patents, in the United States and other countries with respect to any proprietary technology and drug candidates we develop. We seek to protect our proprietary position by filing patent applications in the United States and abroad related to our technology and any drug candidates we may develop that are important to our business and by in-licensing intellectual property related to our technology and drug candidates. If we are unable to obtain or maintain patent protection with respect to any proprietary technology or drug candidate, our business, financial condition, results of operations and prospects could be materially harmed.
The patent prosecution process is expensive, time-consuming and complex, and we may not be able to file, prosecute, maintain, defend, or licence all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection. Moreover, in some circumstances, we may not have the right to control the preparation, filing and prosecution of patent applications, or to maintain, enforce and defend the patents, covering technology that we co-own with third parties or licence from third parties. Therefore, these co-owned and in-licenced patents and applications may not be prepared, filed, prosecuted, maintained, defended and enforced in a manner consistent with the best interests of our business.
The patent position of software and biopharmaceutical companies generally is highly uncertain, involves complex legal and factual questions, and has in recent years been the subject of much litigation. In addition, the scope of patent protection outside of the United States is uncertain and laws of non-U.S. countries may not protect our rights to the same extent as the laws of the United States or vice versa. With respect to both owned and in-licenced patent rights, we cannot predict whether the patent applications we and our licensor are currently pursuing will issue as patents in any particular jurisdiction or whether the claims of any issued patents will provide sufficient protection from competitors. Further, we may not be aware of all third-party intellectual property rights or prior art potentially relating to our technology
42

Table of Contents
platform, other technology and any drug candidates we may develop. In addition, publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing of the priority application, or in some cases not published at all. Therefore, neither we nor our collaborators or our licensor can know with certainty whether we, our collaborators or our licensor were the first to make the inventions claimed in the patents and patent applications we own or in-licence now or in the future, or whether we, our collaborators or our licensor were the first to file for patent protection of such inventions. As a result, the issuance, scope, validity, enforceability and commercial value of our owned, co-owned and in-licenced patent rights are highly uncertain. Moreover, our owned, co-owned and in-licenced pending and future patent applications may not result in patents being issued that protect our technology and drug candidates, in whole or in part, or that effectively prevent others from commercialising competitive technologies and products. Changes in either the patent laws or interpretation of the patent laws in the United States and other countries may diminish the value of our owned, co-owned or in-licenced current or future patents and our ability to obtain, protect, maintain, defend and enforce our patent rights, narrow the scope of our patent protection and, more generally, could affect the value of, or narrow the scope of, our patent rights. For example, recent Supreme Court decisions have served to curtail the scope of subject matter eligible for patent protection in the United States, and many software patents have since been invalidated on the basis that they are directed to abstract ideas.
To pursue protection based on our provisional patent applications, we will need to file Patent Cooperation Treaty applications, non-U.S. applications and/or U.S. non-provisional patent applications prior to applicable deadlines. Even then, as highlighted above, patents may never be issued from our patent applications, or the scope of any patent may not be sufficient to provide a competitive advantage.
Moreover, we, our collaborators or our licensor may be subject to a third-party pre-issuance submission of prior art to the U.S. Patent and Trademark Office, or USPTO, or become involved in opposition, derivation, revocation, re-examination, inter partes review, post-grant review or interference proceedings challenging our patent rights or the patent rights of others. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate, our patent rights or allow third parties to commercialise our technology or drug candidates and compete directly with us, without payment to us. If the breadth or strength of protection provided by our owned, co-owned or in-licenced current or future patents and patent applications is threatened, regardless of the outcome, it could dissuade companies from collaborating with us to licence, develop or commercialise current or future technology or drug candidates.
Additionally, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted after issuance. Even if our owned, co-owned and in-licenced current and future patent applications are issued as patents, they may not be issued in a form that will provide us with any meaningful protection, prevent competitors from competing with us, or otherwise provide us with any competitive advantage. The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability and our owned and in-licenced patents may be challenged in the courts or patent offices in the United States and abroad. Such challenges may result in loss of exclusivity or patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercialising similar or identical technology and products, or limit the duration of the patent protection of our technology and drug candidates. Such proceedings also may result in substantial cost and require significant time from our management and employees, even if the eventual outcome is favourable to us. In particular, given the amount of time required for the development, testing and regulatory review of new drug candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialised. Furthermore, our competitors may be able to circumvent our owned, co-owned or in-licenced current or future patents by developing similar or alternative technologies or products in a non-infringing manner. As a result, our
43

Table of Contents
owned, co-owned and in-licenced current or future patent portfolio may not provide us with sufficient rights to exclude others from commercialising technology and products similar or identical to any of our technology and drug candidates.

Changes to patent laws in the United States and other jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our products.
Changes in either the patent laws or interpretation of patent laws in the United States, including patent reform legislation such as the Leahy-Smith America Invents Act, or the Leahy-Smith Act, could increase the uncertainties and costs surrounding the prosecution of our owned and in-licenced patent applications and the maintenance, enforcement or defence of our owned and in-licenced issued patents. The Leahy-Smith Act includes a number of significant changes to United States patent law. These changes include provisions that affect the way patent applications are prosecuted, redefine prior art, provide more efficient and cost-effective avenues for competitors to challenge the validity of patents, and enable third-party submission of prior art to the USPTO during patent prosecution and additional procedures to attack the validity of a patent at USPTO-administered post-grant proceedings, including post-grant review, inter partes review and derivation proceedings. Assuming that other requirements for patentability are met, prior to March 2013, in the United States, the first to invent the claimed invention was entitled to the patent, while outside the United States, the first to file a patent application was entitled to the patent. After March 2013, under the Leahy-Smith Act, the United States transitioned to a first-to-file system in which, assuming that the other statutory requirements for patentability are met, the first inventor to file a patent application will be entitled to the patent on an invention regardless of whether a third party was the first to invent the claimed invention. As such, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defence of our issued patents, all of which could have a material adverse effect on our business, financial condition, results of operations and prospects.
In addition, the patent positions of companies in the development and commercialisation of software, biologics and pharmaceuticals are particularly uncertain. Recent U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. This combination of events has created uncertainty with respect to the validity and enforceability of patents once obtained. Depending on future actions by the U.S. Congress, the federal courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways that could have a material adverse effect on our patent rights and our ability to protect, defend and enforce our patent rights in the future.
A number of recent cases decided by the U.S. Supreme Court have involved questions of when claims reciting abstract ideas, laws of nature, natural phenomena and/or natural products are eligible for a patent, regardless of whether the claimed subject matter is otherwise novel and inventive. These cases include Association for Molecular Pathology v. Myriad Genetics, Inc., 569 U.S. 12-398 (2013) or Myriad; Alice Corp. v. CLS Bank International, 573 U.S. 13-298 (2014); and Mayo Collaborative Services v. Prometheus Laboratories, Inc., or Prometheus, 566 U.S. 10-1150 (2012). In response to these cases, federal courts have held numerous patents invalid as claiming subject matter ineligible for patent protection. Moreover, the USPTO has issued guidance to the examining corps on how to apply these cases during examination. The full impact of these decisions is not yet known.
In addition to increasing uncertainty with regard to our ability to obtain future patents, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on these and other decisions by Congress, the federal courts and the USPTO, the laws and regulations governing patents could change or be interpreted in unpredictable ways that would weaken our ability to obtain new
44

Table of Contents
patents or to enforce any patents that may issue to us in the future. In addition, these events may adversely affect our ability to defend any patents that may be issued in procedures in the USPTO or in courts.

We, our prior, existing or future collaborators, and our existing or future licensors, may become involved in lawsuits to protect or enforce our patent or other intellectual property rights, which could be expensive, time-consuming and unsuccessful.
Competitors and other third parties may infringe, misappropriate or otherwise violate our, our prior, current and future collaborators’, or our current and future licensors’, issued patents or other intellectual property. As a result, we, our prior, current or future collaborators, or our current or future licensor may need to file infringement, misappropriation or other intellectual property related claims, which can be expensive and time-consuming. Any claims we assert against perceived infringers could provoke such parties to assert counterclaims against us alleging that we infringe, misappropriate or otherwise violate their intellectual property. In addition, in a patent infringement proceeding, such parties could assert that the patents we or our licensors have asserted are invalid or unenforceable. In patent litigation in the United States, defences alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness or non-enablement. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO, or made a misleading statement, during prosecution. Third parties may institute such claims before administrative bodies in the United States or abroad, even outside the context of litigation. Such mechanisms include re-examination, post-grant review, inter partes review, interference proceedings, derivation proceedings and equivalent proceedings in non-U.S. jurisdictions (e.g., opposition proceedings). The outcome following legal assertions of invalidity and unenforceability is unpredictable.
An adverse result in any such proceeding could put one or more of our owned, co-owned or in-licenced current or future patents at risk of being invalidated or interpreted narrowly and could put any of our owned, co-owned or in-licenced current or future patent applications at risk of not yielding an issued patent. A court may also refuse to stop the third party from using the technology at issue in a proceeding on the grounds that our owned, co-owned or in-licenced current or future patents do not cover such technology. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information or trade secrets could be compromised by disclosure during this type of litigation. Any of the foregoing could allow such third parties to develop and commercialise competing technologies and products in a non-infringing manner and have a material adverse impact on our business, financial condition, results of operations and prospects.
Interference or derivation proceedings provoked by third parties, or brought by us or by our licensor, or declared by the USPTO may be necessary to determine the priority of inventions with respect to our patents or patent applications. An unfavourable outcome could require us to cease using the related technology or to attempt to licence rights to it from the prevailing party. Our business could be harmed if the prevailing party does not offer us a licence on commercially reasonable terms or at all, or if a non-exclusive licence is offered and our competitors gain access to the same technology. Our defence of litigation or interference or derivation proceedings may fail and, even if successful, may result in substantial costs and distract our management and other employees. In addition, the uncertainties associated with litigation could have a material adverse effect on our ability to raise the funds necessary to conduct clinical trials, continue our research programmes, licence necessary technology from third parties, or enter into development collaborations that would help us bring any drug candidates to market.
45

Table of Contents
Third parties may initiate legal proceedings alleging that we are infringing, misappropriating or otherwise violating their intellectual property rights, the outcome of which would be uncertain and could have a material adverse effect on the success of our business.
Our commercial success will depend upon our ability and the ability of our collaborators to develop, manufacture, market and sell any drug candidates we may develop and for our collaborators, customers and partners to use our proprietary technologies without infringing, misappropriating or otherwise violating the intellectual property and proprietary rights of third parties. There is considerable patent and other intellectual property litigation in the software, pharmaceutical and biotechnology industries. We may become party to, or threatened with, adversarial proceedings or litigation regarding intellectual property rights with respect to our technology and drug candidates, including interference proceedings, post grant review, inter partes review and derivation proceedings before the USPTO and similar proceedings in non-U.S. jurisdictions such as oppositions before the European Patent Office. Numerous U.S. and non-U.S. issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we are pursuing development candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that our technologies or drug candidates that we may identify may be subject to claims of infringement of the patent rights of third parties.
The legal threshold for initiating litigation or contested proceedings is low, so that even lawsuits or proceedings with a low probability of success might be initiated and require significant resources to defend. Litigation and contested proceedings can also be expensive and time-consuming, and our adversaries in these proceedings may have the ability to dedicate substantially greater resources to prosecuting these legal actions than we can. The risks of being involved in such litigation and proceedings may increase if and as any drug candidates near commercialisation and as we gain the greater visibility associated with being a public company. Third parties may assert infringement claims against us based on existing patents or patents that may be granted in the future, regardless of merit. We may not be aware of all such intellectual property rights potentially relating to our technology and drug candidates and their uses, or we may incorrectly conclude that third-party intellectual property is invalid or that our activities and drug candidates do not infringe such intellectual property. Thus, we do not know with certainty that our technology and drug candidates, or our development and commercialisation thereof, do not and will not infringe, misappropriate or otherwise violate any third party’s intellectual property.
Third parties may assert that we are employing their proprietary technology without authorisation. There may be third-party patents or patent applications with claims to materials, formulations or methods, such as methods of manufacture or methods for treatment, related to the discovery, use or manufacture of the drug candidates that we may identify or otherwise related to our technologies. Because patent applications can take many years to issue, there may be currently pending patent applications which may later result in issued patents that the drug candidates that we may identify may infringe. In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. Moreover, as noted above, there may be existing patents that we are not aware of or that we have incorrectly concluded are invalid or not infringed by our activities. If any third-party patents were held by a court of competent jurisdiction to cover, for example, the manufacturing process of the drug candidates that we may identify, any molecules formed during the manufacturing process or any final product itself, the holders of any such patents may be able to block our ability to commercialise such drug candidate unless we obtained a licence under the applicable patents, or until such patents expire.
Parties making claims against us may obtain injunctive or other equitable relief, which could effectively block our ability to further develop and commercialise the drug candidates that we may identify. Defence of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business. In the event of a successful claim of infringement against us, we may have to pay substantial damages, including treble damages and
46

attorneys’ fees for wilful infringement, pay royalties, redesign our infringing products, be forced to indemnify our customers or collaborators or obtain one or more licences from third parties, which may be impossible or require substantial time and monetary expenditure.
We may choose to take a licence or, if we are found to infringe, misappropriate or otherwise violate a third party’s intellectual property rights, we could also be required to obtain a licence from such third party to continue developing, manufacturing and marketing our technology and drug candidates. However, we may not be able to obtain any required licence on commercially reasonable terms or at all. Even if we were able to obtain a licence, it could be non-exclusive, thereby giving our competitors and other third parties access to the same technologies licenced to us and could require us to make substantial licensing and royalty payments. We could be forced, including by court order, to cease developing, manufacturing and commercialising the infringing technology or product. A finding of infringement could prevent us from commercialising any drug candidates or force us to cease some of our business operations, which could materially harm our business. In addition, we may be forced to redesign any drug candidates, seek new regulatory approvals and indemnify third parties pursuant to contractual agreements. Claims that we have misappropriated the confidential information or trade secrets of third parties could have a similar material adverse effect on our business, financial condition, results of operations and prospects.

We may be subject to claims by third parties asserting that our employees, consultants or contractors have wrongfully used or disclosed confidential information of third parties, or we have wrongfully used or disclosed alleged trade secrets of their current or former employers or claims asserting we have misappropriated their intellectual property, or claiming ownership of what we regard as our own intellectual property.
Certain of our employees, consultants and contractors were previously employed at universities or other software or biopharmaceutical companies, including our competitors or potential competitors.
Although we try to ensure that our employees, consultants and contractors do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that these individuals or we have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such individual’s current or former employer. Litigation may be necessary to defend against these claims.
In addition, while it is our policy to require that our employees, consultants and contractors who may be involved in the development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who in fact develops intellectual property that we regard as our own. Our intellectual property assignment agreements with them may not be self-executing or may be breached, and we may be forced to bring claims against third parties, or defend claims they may bring against us, to determine the ownership of what we regard as our intellectual property. Such claims could have a material adverse effect on our business, financial condition, results of operations and prospects.
If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel, which could have a material adverse effect on our competitive business position and prospects. Such intellectual property rights could be awarded to a third party, and we could be required to obtain a licence from such third party to commercialise our technology or products, which licence may not be available on commercially reasonable terms, or at all, or such licence may be non-exclusive. Even if we are successful in prosecuting or defending against such claims, litigation could result in substantial costs and be a distraction to our management and employees.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position may be harmed.
In addition to seeking patents for our drug candidates and certain aspects of our technology platform, we also rely on trade secrets and confidentiality agreements to protect our unpatented know-how, technology and other proprietary information. In particular, the software code underlying our technology platform is generally protected through trade secret laws rather than through patent law. We seek to protect our trade secrets and other proprietary technology, in part, by entering into non-disclosure and confidentiality agreements with parties who have access to them, such as our employees, corporate collaborators, outside scientific collaborators, CROs, contract manufacturers, consultants, advisors, collaborators and other third parties. We also enter into confidentiality and invention or patent assignment agreements with our employees and consultants, but we cannot guarantee that we have entered into such agreements with each party that may have or has had access to our trade secrets or proprietary technology. Despite these efforts, any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Detecting the disclosure or misappropriation of a trade secret and enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside of the United States have appeared to be unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor or other third party, we would have no right to prevent them, or those to whom they communicate such trade secrets, from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor or other third party, our competitive position may be materially and adversely harmed.

Risks Related to Government Regulation and Legal Compliance Matters
We are subject to stringent and evolving global laws, regulations, and rules, contractual obligations, industry standards, policies and other obligations related to data privacy and security. Our actual or perceived failure to comply with such obligations could result in additional costs and liabilities to us or inhibit our ability to collect and process data globally, and could lead to regulatory investigations or actions; litigation (including class claims) and mass arbitration demands; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; and other adverse business consequences.
In the ordinary course of business, we collect, receive, store, process, generate, use, transfer, disclose, make accessible, protect, secure, dispose of, transmit, and share (collectively, process) personal data and other sensitive information, including proprietary and confidential business data, trade secrets, intellectual property, data we collect about trial participants in connection with clinical trials, sensitive third-party data, and other sensitive data we may process, e.g., business plans, transactions, or financial information. Our data processing activities subject us to numerous data privacy and security obligations, such as various laws, regulations, guidance, industry standards, external and internal privacy and security policies, contractual requirements, and other obligations relating to data privacy and security.
Accordingly, we are, or may become, subject to data privacy and security laws, regulations and industry standards as well as policies, contracts and other obligations that apply to the processing of personal data both by us and on our behalf, which we refer to collectively as Data Protection Requirements. If we fail, or are perceived to have failed, to address or comply with Data Protection Requirements, this could result in government enforcement actions against us that could include investigations, fines, penalties, audits and inspections, additional reporting requirements and/or oversight, temporary or permanent bans on all or some processing of personal data, orders to destroy or not use personal data and imprisonment of

company officials. Further, individuals or other relevant stakeholders could bring a variety of claims against us for our actual or perceived failure to comply with Data Protection Requirements.
In Europe, the E.U. and the U.K. General Data Protection Regulations, (respectively, the “E.U. GDPR” and the “U.K. GDPR”, together the "GDPR") each impose strict requirements around the processing of personal data: Under the GDPR, companies may face temporary or definitive bans on data processing and other corrective actions; fines of up to 20 million Euros under the E.U. GDPR, 17.5 million pounds sterling under the U.K. GDPR or, in each case, 4% of annual global revenue, whichever is greater; or private litigation related to processing of personal data brought by classes of data subjects or consumer protection organizations authorized at law to represent their interests. Other countries outside of Europe have enacted or are considering enacting similar comprehensive data privacy and security laws and regulations, which could increase the cost and complexity of operating our business. Complying with these and other similar laws, regulations and practices across Europe and elsewhere may cause us to incur substantial operational costs or require us to change our business practices, and could expose us to risks of material fines, penalties and liability.
In the ordinary course of business, we may transfer personal data from Europe and other jurisdictions to the United States or other countries. Europe and other jurisdictions have enacted laws requiring data to be localized or limiting the transfer of personal data to other countries. In particular, the European Economic Area, or “EEA”, and the United Kingdom have significantly restricted the transfer of personal data to the United States and other countries whose privacy laws it generally believes are inadequate. Other jurisdictions may adopt similarly stringent interpretations of their data localization and cross-border data transfer laws. Although there are currently various mechanisms that may be used to transfer personal data from the EEA and United Kingdom to the United States in compliance with law, such as the European Commission’s Standard Contractual Clauses, the United Kingdom’s International Data Transfer Agreement and United Kingdom Transfer Addendum, and the E.U.-U.S. Data Privacy Framework and the United Kingdom’s Extension to that Framework (which allows for transfers for relevant U.S.-based organizations who self-certify compliance and participate in the relevant Framework and/or Extension), these mechanisms are subject to potential legal challenges, and there is no assurance that we can satisfy or rely on these measures to lawfully transfer personal data to the United States. If there is no lawful manner for us to transfer personal data from the EEA, the United Kingdom or other jurisdictions to the United States, or if the requirements for a legally-compliant transfer are too onerous, we could face significant adverse consequences, including the interruption or degradation of our operations, the need to relocate part of or all of our business or data processing activities to other jurisdictions (such as Europe) at significant expense, increased exposure to regulatory actions, substantial fines and penalties, the inability to transfer data and work with partners, vendors and other third parties, and injunctions against our processing or transferring of personal data necessary to operate our business. Additionally, companies that transfer personal data out of the EEA and United Kingdom to other jurisdictions, particularly to the United States, are subject to increased scrutiny from regulators, individual litigants, and activist groups. Some European regulators have ordered certain companies to suspend or permanently cease certain transfers out of Europe for allegedly violating the GDPR’s cross-border data transfer limitations.
In addition, analysis of certain concepts that are fundamental to E.U. GDPR and the U.K. GDPR compliance are highly complex and open to subjective interpretation—particularly so in respect of processing that occurs in multi-party data processing environments such as those in which we operate our business. For example, in contexts such as these, classification of an organisation’s role in relation to any given processing and the appropriate legal basis for that processing (where required)—each of which is foundational to determining the nature of that organisation’s compliance obligations—requires a subjective analysis of the factual circumstances at hand on a case-by-case basis, which may be open to divergent and/or contradictory conclusions and/or regulatory guidance.

Generally, these laws exemplify the vulnerability of our business to the evolving regulatory environment related to personal data and may require us to modify our processing practices at substantial costs and expenses in an effort to comply. Changes in laws or regulations in this area could require us to change our business practices and put in place additional compliance mechanisms, may interrupt or delay our development, regulatory and commercialisation activities and increase our cost of doing business, and could lead to government enforcement actions, private litigation and significant fines and penalties against us, and could have a material adverse effect on our business, financial condition or results of operations.
In the past few years, numerous U.S. states—including California, Virginia, Colorado, Connecticut, and Utah—have enacted comprehensive privacy laws that impose certain obligations on covered businesses, including providing specific disclosures in privacy notices and affording residents with certain rights concerning their personal data. As applicable, such rights may include the right to access, correct, or delete certain personal data, and to opt-out of certain data processing activities, such as targeted advertising, profiling, and automated decision-making. The exercise of these rights may impact our business and ability to provide our products and services.
Certain states also impose stricter requirements for processing certain personal data, including sensitive information, such as conducting data privacy impact assessments. These state laws allow for statutory fines for noncompliance. For example, the California Consumer Privacy Act of 2018, as amended by the California Privacy Rights Act of 2020, or “CPRA”, (collectively, “CCPA”) applies to personal data of consumers, business representatives, and employees who are California residents, and requires businesses to provide specific disclosures in privacy notices and honor requests of such individuals to exercise certain privacy rights. The CCPA provides for fines of up to $7,500 per intentional violation and allows private litigants affected by certain data breaches to recover significant statutory damages. Although the CCPA exempts some data processed in the context of clinical trials, the CCPA increases compliance costs and potential liability with respect to other personal data we maintain about California residents. Similar laws are being considered in several other states, as well as at the federal and local levels, and we expect more states to pass similar laws in the future. While these states, like the CCPA, also exempt some data processed in the context of clinical trials, these developments further complicate compliance efforts, and increase legal risk and compliance costs for us, the third parties upon whom we rely. While we are not subject to the CCPA or CPRA at present, we may be if we expand our operations to California. Many other states are considering similar legislation.
A broad range of legislative measures also have been introduced at the federal level. Accordingly, failure to comply with current and any future federal and state laws regarding privacy and security of personal information could expose us to fines and penalties. We also face a threat of consumer class actions related to these laws and the overall protection of personal data. Even if we are not determined to have violated these laws, investigations into these issues typically require the expenditure of significant resources and generate negative publicity, which could harm our reputation and our business.
Additionally, regulations promulgated pursuant to the Health Insurance Portability and Accountability Act of 1996, or HIPAA, establish privacy and security standards that limit the use and disclosure of individually identifiable health information, or protected health information, and require the implementation of administrative, physical and technological safeguards designed to protect the privacy, confidentiality, integrity and availability of protected health information. These provisions may be applicable to our business or that of our collaborators, service providers, contractors or consultants.
We may also publish privacy policies and other documentation regarding our processing of personal data and/or other confidential, proprietary or sensitive information. Although we endeavour to comply with our published policies and other documentation, we may at times fail to do so or may be perceived to have failed to do so. Moreover, despite our efforts, we may not be successful in achieving compliance if
50

Table of Contents
our employees, third-party collaborators, service providers, contractors or consultants fail to comply with our policies and documentation. Such failures can subject us to potential foreign, local, state and federal action if they are found to be deceptive, unfair or misrepresentative of our actual practices.
We may at times fail (or be perceived to have failed) in our efforts to comply with our data privacy and security obligations. Moreover, despite our efforts, our personnel or third parties on whom we rely may fail to comply with such obligations, which could negatively impact our business operations.
If we or the third parties on which we rely fail, or are perceived to have failed, to address or comply with applicable data privacy and security obligations, we could face significant consequences, including but not limited to: government enforcement actions (e.g., investigations, fines, penalties, audits, inspections, and similar); litigation (including class-action claims) and mass arbitration demands; additional reporting requirements and/or oversight; bans on processing personal data; orders to destroy or not use personal data; and imprisonment of company officials.
Any of these events could have a material adverse effect on our reputation, business, or financial condition, including but not limited to: loss of customers; interruptions or stoppages in our business operations (including clinical trials); interruptions or stoppages of data collection needed to train our algorithms; inability to process personal data or to operate in certain jurisdictions; limited ability to develop or commercialize our products; expenditure of time and resources to defend any claim or inquiry; adverse publicity; or substantial changes to our business model or operations.

We, and our collaborators may be subject to applicable anti-kickback, fraud and abuse, false claims, transparency, health information privacy and security and other healthcare laws and regulations. Failure to comply with such laws and regulations may result in substantial penalties.
We and our collaborators may be subject to broadly applicable healthcare laws and regulations that may constrain our relationships with our drug discovery collaborators and any products for which we obtain marketing approval. Such healthcare laws and regulations include, but are not limited to:
The Federal Anti-kickback Statute, which prohibits any person or entity from, among other things, knowingly and wilfully soliciting, receiving, offering or paying any remuneration, directly or indirectly, overtly or covertly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, order or recommendation of an item or service reimbursable, in whole or in part, under a federal healthcare programme, such as the Medicare and Medicaid programmes. The term “remuneration” has been broadly interpreted to include anything of value. The Federal Anti-kickback Statute has also been interpreted to apply to arrangements between pharmaceutical manufacturers on the one hand and prescribers, purchasers and formulary managers on the other hand. There is a number of statutory exceptions and regulatory safe harbours protecting some common activities from prosecution, but the exceptions and safe harbours are drawn narrowly and require strict compliance to offer protection. Additionally, the intent standard under the Federal Anti-kickback Statute was amended by the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively the ACA, to a stricter standard such that a person or entity does not need to have actual knowledge of the statute or specific intent to violate it to have committed a violation. Further, the ACA codified case law that a claim including items or services resulting from a violation of the Federal Anti-kickback Statute constitutes a false or fraudulent claim for purposes of the civil False Claims Act, or the FCA.
51

Table of Contents
Federal civil and criminal false claims laws, such as the FCA, which can be enforced by private citizens through civil qui tam actions, and civil monetary penalty laws prohibit individuals or entities from, among other things, knowingly presenting, or causing to be presented, false, fictitious or fraudulent claims for payment of federal funds, and knowingly making, using or causing to be made or used a false record or statement material to a false or fraudulent claim to avoid, decrease or conceal an obligation to pay money to the federal government. For example, pharmaceutical companies have been prosecuted under the FCA in connection with their alleged off-label promotion of drugs, purportedly concealing price concessions in the pricing information submitted to the government for government price reporting purposes, and allegedly providing free product to customers with the expectation that the customers would bill federal healthcare programmes for the product. In addition, a claim including items or services resulting from a violation of the Federal Anti-kickback Statute constitutes a false or fraudulent claim for purposes of the FCA. As a result of a modification made by the Fraud Enforcement and Recovery Act of 2009, a claim includes “any request or demand” for money or property presented to the U.S. government. In addition, manufacturers can be held liable under the FCA even when they do not submit claims directly to government payors if they are deemed to “cause” the submission of false or fraudulent claims.
HIPAA, among other things, imposes criminal liability for executing or attempting to execute a scheme to defraud any healthcare benefit programme, including private third-party payors, knowingly and wilfully embezzling or stealing from a healthcare benefit programme, wilfully obstructing a criminal investigation of a healthcare offence, and creates federal criminal laws that prohibit knowingly and wilfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement or representation, or making or using any false writing or document knowing the same to contain any materially false, fictitious or fraudulent statement or entry in connection with the delivery of or payment for healthcare benefits, items or services
HIPAA, as amended by Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and their implementing regulations, which impose privacy, security and breach reporting obligations with respect to individually identifiable health information upon entities subject to the law, such as health plans, healthcare clearinghouses and certain healthcare providers, known as covered entities, and their respective business associates and subcontractors that perform services for them that involve individually identifiable health information. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in U.S. federal courts to enforce HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions.
Federal and state consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm consumers.
The federal transparency requirements under the Physician Payments Sunshine Act, created under the ACA, which requires, among other things, certain manufacturers of drugs, devices, biologics and medical supplies reimbursed under Medicare, Medicaid, or the Children’s Health Insurance Programme to report annually to the Centers for Medicare & Medicaid Services, or CMS, information related to payments and other transfers of value provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors), other healthcare professionals (such as physician assistants and nurse practitioners) and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members.
State and foreign laws that are analogous to each of the above federal laws, such as anti-kickback and false claims laws, that may impose similar or more prohibitive restrictions, and may apply to items or services reimbursed by non-governmental third-party payors, including private insurers.
52

Table of Contents
State and foreign laws that require pharmaceutical companies to implement compliance programmes, comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the government, or to track and report gifts, compensation and other remuneration provided to physicians and other healthcare providers; state laws that require the reporting of marketing expenditures or drug pricing, including information pertaining to and justifying price increases; state and local laws that require the registration of pharmaceutical sales representatives; state and foreign laws that prohibit various marketing-related activities, such as the provision of certain kinds of gifts or meals; state and foreign laws that require the posting of information relating to clinical trials and their outcomes; and other federal, state and foreign laws that govern the privacy and security of personal data, health information or personally identifiable information in certain circumstances, including state health information privacy and data breach notification laws which govern the collection, use, disclosure and protection of health-related and other personal information, many of which differ from each other in significant ways and often are not pre-empted by HIPAA, thus requiring additional compliance efforts.
Outside the United States, interactions between pharmaceutical companies and healthcare professionals are also governed by strict laws, such as national anti-bribery laws of European countries, national sunshine rules, regulations, industry self-regulation codes of conduct and physicians’ codes of professional conduct. Failure to comply with these requirements could result in reputational risk, public reprimands, administrative penalties, fines or imprisonment.
Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. Violations of applicable healthcare laws and regulations may result in significant civil, criminal and administrative penalties, damages, disgorgement, fines, individual imprisonment, exclusion of products from government funded healthcare programmes, such as Medicare and Medicaid or comparable programs outside of the United States, additional reporting requirements and/or oversight if a corporate integrity agreement or similar agreement is executed to resolve allegations of non-compliance with these laws and the curtailment or restructuring of operations. In addition, violations may also result in reputational harm, diminished profits and future earnings.

Current and future healthcare legislative reform measures may have a material adverse effect on our business and results of operations.
In the United States and in some foreign jurisdictions, there have been, and likely will continue to be, a number of legislative and regulatory changes and proposed changes intended to broaden access to healthcare, improve the quality of healthcare and contain or lower the cost of healthcare. For example, in March 2010, the ACA, was passed, which substantially changed the way healthcare is financed by both governmental and private insurers, and significantly impacted the U.S. pharmaceutical industry. The ACA, among other things, subjects biological products to potential competition by lower-cost biosimilars, expands the types of entities eligible for the 340B drug discount programme, addresses a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Programme are calculated for drugs that are inhaled, infused, instilled, implanted or injected, increases rebates owed by manufacturers under the Medicaid Drug Rebate Programme and extends the rebate programme to individuals enrolled in Medicaid managed care organisations, establishes annual fees and taxes on manufacturers of certain branded prescription drugs and creates a new Medicare Part D coverage gap discount programme, in which manufacturers must agree to offer 50% (increased to 70% pursuant to the Bipartisan Budget Act of 2018, or BBA, effective as of January 2019) point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D.

Since its enactment, there have been numerous judicial, administrative, executive and legislative challenges to certain aspects of the ACA, and we expect there will be additional challenges and amendments to the ACA in the future. Various portions of the ACA are currently undergoing legal and constitutional challenges in the United States Supreme Court and members of Congress have introduced several pieces of legislation aimed at significantly revising or repealing the ACA. On June 17, 2021 the U.S. Supreme Court dismissed a challenge on procedural grounds that argued the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. Prior to the Supreme Court ruling, on January 28, 2021, President Biden issued an executive order to initiate a special enrolment period for purposes of obtaining health insurance coverage through the ACA marketplace. On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022 (“IRA”) into law, which among other things, extends enhanced subsidies for individuals purchasing health insurance coverage in ACA marketplaces through plan year 2025. The IRA also eliminates the “donut hole” under the Medicare Part D programme beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost through a newly established manufacturer discount programme. The implementation of the ACA is ongoing, and the law appears likely to continue the downward pressure on pharmaceutical pricing, especially under the Medicare programme, and may also increase our regulatory burdens and operating costs. Litigation and legislation related to the ACA are likely to continue, with unpredictable and uncertain results.
In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted. For example, in August 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. Specifically, the Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programmes. This includes aggregate reductions of Medicare payments to providers of up to 2% per fiscal year, which went into effect in April 2013, and, due to subsequent legislative amendments, will remain in effect through 2032 unless additional Congressional action is taken. On January 2, 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several providers, including hospitals, imaging centres and cancer treatment centres, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. The BBA also amended the ACA, effective January 1, 2019, by increasing the point-of-sale discount that is owed by pharmaceutical manufacturers who participate in Medicare Part D and closing the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole.”
Furthermore, there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in several congressional inquiries and proposed legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient assistance programmes and reform government programme reimbursement methodologies for pharmaceutical and biological products. At the federal level, the previous administration used several means to propose or implement drug pricing reform, including through federal budget proposals, executive orders and policy initiatives. In July 2021, President Biden issued an executive order directing the FDA to, among other things, continue to clarify and improve the approval framework for generic drugs and identify and address any efforts to impede generic drug competition. Individual states in the United States have also become increasingly active in passing legislation and implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programmes. It is
54

Table of Contents
difficult to predict the future legislative landscape in healthcare and the effect on our business, results of operations, financial condition and prospects. However, we expect that additional state and federal healthcare reform measures will be adopted in the future, particularly in light of the new presidential administration.
In addition, the IRA will, among other things, (i) allow HHS to negotiate the price of certain drugs and biologics covered under Medicare, and subject drug manufacturers to civil monetary penalties and a potential excise tax by offering a price that is not equal to or less than the negotiated “maximum fair price” under the law, and (ii) impose rebates under Medicare Part B and Medicare Part D to penalize price increases that outpace inflation. The IRA permits HHS to implement many of these provisions through guidance, as opposed to regulation, for the initial years. These provisions take effect progressively starting in 2023, although the Medicare drug price negotiation program is currently subject to legal challenges. It is currently unclear how the IRA will be effectuated but is likely to have a significant impact on the pharmaceutical industry. In response to the Biden administration’s October 2022 executive order, on February 14, 2023, HHS released a report outlining three new models for testing by the CMS Innovation Center which will be evaluated on their ability to lower the cost of drugs, promote accessibility, and improve quality of care. It is unclear whether the models will be utilized in any health reform measures in the future. Further, on December 7, 2023, the Biden administration announced an initiative to control the price of prescription drugs through the use of march-in rights under the Bayh-Dole Act. On December 8, 2023, the National Institute of Standards and Technology published for comment a Draft Interagency Guidance Framework for Considering the Exercise of March-In Rights which for the first time includes the price of a product as one factor an agency can use when deciding to exercise march-in rights. While march-in rights have not previously been exercised, it is uncertain if that will continue under the new framework.
At the state level, individual states are increasingly aggressive in passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.For example, on January 5, 2024, the FDA approved Florida’s Section 804 Importation Program (SIP) proposal to import certain drugs from Canada for specific state healthcare programs. It is unclear how this program will be implemented, including which drugs will be chosen, and whether it will be subject to legal challenges in the United States or Canada. Other states have also submitted SIP proposals that are pending review by the FDA. Any such approved importation plans, when implemented, may result in lower drug prices for products covered by those programs. In addition, regional health care authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other health care programmes. These measures could reduce the ultimate demand for our products, once approved, or put pressure on our product pricing.
We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our services by our partners or for our current or future drug candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action in the United States. If we or any third parties we may engage are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we or such third parties are not able to maintain regulatory compliance, our drug candidates may lose any regulatory approval that may have been obtained and we may not achieve or sustain profitability.

We are subject to anti-corruption laws, as well as export control laws, customs laws, sanctions laws and other laws governing our operations. If we fail to comply with these laws, we could be subject to civil or criminal penalties, other remedial measures and legal expenses, be precluded from developing, manufacturing and selling certain products outside the United States or be required to develop and implement costly compliance programmes, which could adversely affect our business, results of operations and financial condition.
Our operations are subject to anti-corruption laws, including the U.K. Bribery Act 2010, or Bribery Act, the U.S. Foreign Corrupt Practices Act, or FCPA, and other anti-corruption laws that apply in countries where we do business and may do business in the future. The Bribery Act, FCPA and these other laws generally prohibit us, our officers and our employees and intermediaries from bribing, being bribed, or making other prohibited payments to government officials or other persons to obtain or retain business or gain some other business advantage. Compliance with the FCPA, in particular, is expensive and difficult, particularly in countries in which corruption is a recognised problem. In addition, the FCPA presents particular challenges in the biopharmaceutical industry, because, in many countries, hospitals are operated by the government, and doctors and other hospital employees are considered foreign officials. Certain payments to hospitals in connection with clinical trials and other work have been deemed to be improper payments to government officials and have led to FCPA enforcement actions.
We currently have operations in China, and we may in the future operate in additional jurisdictions that pose a high risk of potential Bribery Act or FCPA violations, and we may participate in collaborations and relationships with third parties whose actions could potentially subject us to liability under the Bribery Act, FCPA, or local anti-corruption laws. In addition, we cannot predict the nature, scope or effect of future regulatory requirements to which our international operations might be subject or the manner in which existing laws might be administered or interpreted. If we further expand our operations outside of the United States and the United Kingdom, we will need to dedicate additional resources to comply with numerous laws and regulations in each jurisdiction in which we plan to operate.
We are also subject to other laws and regulations governing our international operations, including regulations administered by the governments of the United Kingdom and the United States, and authorities in the European Union, including applicable export control regulations, economic sanctions on countries and persons, customs requirements and currency exchange regulations, collectively referred to as the Trade Control laws. In addition, various laws, regulations and executive orders also restrict the use and dissemination outside of the United States, or the sharing with certain non-U.S. nationals, of information classified for national security purposes, as well as certain products and technical data relating to those products. If we expand our presence outside of the United States, it will require us to dedicate additional resources to comply with these laws, and these laws may preclude us from developing, manufacturing or selling certain products and drug candidates outside of the United States, which could limit our growth potential and increase our development costs.
There is no assurance that we will be completely effective in ensuring our compliance with all applicable anti-corruption laws, including the Bribery Act, the FCPA, or other legal requirements, including Trade Control laws. If we are not in compliance with the Bribery Act, the FCPA and other anti-corruption laws or Trade Control laws, we may be subject to criminal and civil penalties, disgorgement and other sanctions and remedial measures and legal expenses, which could have an adverse impact on our business, financial condition, results of operations and liquidity. The U.S. Securities and Exchange Commission, or SEC, also may suspend or bar issuers from trading securities on U.S. exchanges for violations of the FCPA’s accounting provisions. Any investigation of any potential violations of the Bribery Act, the FCPA, other anti-corruption laws or Trade Control laws by United Kingdom, U.S. or other authorities could also have an adverse impact on our reputation, our business, results of operations and financial condition.

Any drug candidates we develop may become subject to unfavourable third-party coverage and reimbursement practices, as well as pricing regulations.
The availability and extent of coverage and adequate reimbursement by third-party payors, including government health authorities, private health coverage insurers, managed care organisations and other third-party payors is essential for most patients to be able to afford expensive treatments. Sales of any of our drug candidates that receive marketing approval will depend substantially, both in the United States and internationally, on the extent to which the costs of such drug candidates will be covered and reimbursed by third-party payors. If reimbursement is not available, or is available only to limited levels, we may not be able to successfully commercialise our drug candidates. Even if coverage is provided, the approved reimbursement amount may not be high enough to allow us to establish or maintain pricing sufficient to realise an adequate return on our investment. Coverage and reimbursement may impact the demand for, or the price of, any drug candidate for which we obtain marketing approval. If coverage and reimbursement are not available or reimbursement is available only to limited levels, we may not successfully commercialise any drug candidate for which we obtain marketing approval.
There is significant uncertainty related to third-party payor coverage and reimbursement of newly approved products. In the United States, for example, principal decisions about reimbursement for new drug products are typically made by CMS, an agency within HHS. CMS decides whether and to what extent a new drug product will be covered and reimbursed under Medicare, and private third-party payors often follow CMS’s decisions regarding coverage and reimbursement to a substantial degree. However, one third-party payor’s determination to provide coverage for a product candidate does not assure that other payors will also provide coverage for the product candidate. Further, no uniform policy for coverage and reimbursement exists in the United States, and coverage and reimbursement can differ significantly from payor to payor. As a result, the coverage determination process is often time-consuming and costly. This process will require us to provide scientific and clinical support for the use of our drug products to each third-party payor separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance.
Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. Further, such payors are increasingly challenging the price, examining the medical necessity and reviewing the cost effectiveness of medical drug candidates. There may be especially significant delays in obtaining coverage and reimbursement for newly approved drugs. Third-party payors may limit coverage to specific drug candidates on an approved list, known as a formulary, which might not include all FDA-approved drugs for a particular indication. We may need to conduct expensive pharmaco-economic studies to demonstrate the medical necessity and cost effectiveness of our products. Nonetheless, our drug candidates may not be considered medically necessary or cost effective. We cannot be sure that coverage and reimbursement will be available for any product that we commercialise and, if reimbursement is available, what the level of reimbursement will be.
Outside the United States, reimbursement and healthcare payment systems vary significantly by country, and many countries have instituted price ceilings on specific products and therapies. The E.U. provides options for E.U. Member States to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. An E.U. Member State may approve a specific price for the medicinal product, it may refuse to reimburse a product at the price set by the manufacturer or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. Many E.U. Member States also periodically review their reimbursement procedures for medicinal products, which could have an adverse impact on reimbursement status. Moreover, in order to obtain reimbursement for our products in some European countries, including some E.U. Member States, we may be required to
57

Table of Contents
compile additional data comparing the cost-effectiveness of our products to other available therapies. Further, an increasing number of E.U. and other foreign countries use prices for medicinal products established in other countries as “reference prices” to help determine the price of the product in their own territory. Consequently, a downward trend in prices of medicinal products in some countries could contribute to similar downward trends elsewhere.
If we are unable to establish or sustain coverage and adequate reimbursement for any drug candidates, if approved, from third-party payors, the adoption of those products and sales revenue will be adversely affected, which, in turn, could adversely affect the ability to market or sell those drug candidates, if approved. Coverage policies and third-party payor reimbursement rates may change at any time. Even if favourable coverage and reimbursement status is attained for one or more products for which we receive regulatory approval, less favourable coverage policies and reimbursement rates may be implemented in the future. Additionally, any companion diagnostic test that we develop will be required to obtain coverage and reimbursement separate and apart from the coverage and reimbursement we seek for our product candidates, if approved. If any companion diagnostic is unable to obtain reimbursement or is inadequately reimbursed, that may limit the availability of such companion diagnostic, which would negatively impact prescriptions for our product candidates, if approved.

Our employees, independent contractors, consultants and vendors may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements and insider trading laws, which could cause significant liability for us and harm our reputation.
We are exposed to the risk of fraud or other misconduct by our employees, independent contractors, consultants and vendors. Misconduct by these partners could include intentional failures to comply with FDA regulations or similar regulations of comparable non-U.S. regulatory authorities, provide accurate information to the FDA or comparable non-U.S. regulatory authorities, comply with manufacturing standards, comply with federal and state healthcare fraud and abuse laws and regulations and similar laws and regulations established and enforced by comparable non-U.S. regulatory authorities, report financial information or data accurately or disclose unauthorised activities to us. Employee misconduct could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. This could include violations of HIPAA, other U.S. federal and state law and requirements of non-U.S. jurisdictions, including the European Union Data Protection Regulation. We are also exposed to risks in connection with any insider trading violations by employees or others affiliated with us. It is not always possible to identify and deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws, standards, regulations, guidance or codes of conduct. Furthermore, our employees may, from time to time, bring lawsuits against us for employment issues, including injury, discrimination, wage and hour disputes, sexual harassment, hostile work environment or other employment issues. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business and results of operations, including the imposition of significant fines or other sanctions.

Our internal information technology systems, or those of our third-party vendors, contractors or consultants, may fail or suffer security breaches, loss or leakage of data and other disruptions, which could result in adverse consequences resulting from any such incident, including but not limited to regulatory investigations or actions; litigation; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; loss of customers or sales; and other adverse consequences.
We are increasingly dependent upon information technology systems, infrastructure and data to operate our business. In the ordinary course of business, we collect, store, process and transmit confidential information (including but not limited to intellectual property, proprietary business information and personal information). It is critical that we do so in a secure manner to maintain the confidentiality and integrity of such confidential information. We also have outsourced elements of our operations to third parties, and as a result we manage a number of third-party vendors and other contractors and consultants who have access to our confidential information. We may be required to expend significant resources, at significant cost, materially change our business activities and practices or modify our operations, including our clinical trial activities, or information technology in an effort to protect against security breaches and to mitigate, detect and remediate actual or potential vulnerabilities as well as security breaches.
Given the size and complexity of our internal information technology systems and those of our third-party vendors and other contractors and consultants, and the increasing amounts of confidential information that they maintain, our information technology systems are potentially vulnerable to breakdown or other damage or interruption from service interruptions, system malfunction, natural disasters (whether due to environmental or other factors such as climate change), terrorism, war and telecommunication and electrical failures, as well as security breaches from inadvertent or intentional actions by our employees, third-party vendors, contractors, consultants, business partners and/or other third parties or from cyber attacks by malicious third parties (including the deployment of harmful malware, ransomware, distributed denial-of-service attacks, social engineering and other means to affect service reliability and threaten the confidentiality, integrity and availability of information), which may compromise our system infrastructure, or that of our third-party vendors and other contractors and consultants or lead to data leakage.
In particular, severe ransomware attacks are becoming increasingly prevalent and can lead to significant interruptions in our operations, ability to provide our products or services, loss of sensitive data and income, reputational harm, and diversion of funds. Extortion payments may alleviate the negative impact of a ransomware attack, but we may be unwilling or unable to make such payments due to, for example, applicable laws or regulations prohibiting such payments.
The risk of a security breach or disruption, particularly through cyber attacks or cyber intrusion, including by computer hackers, foreign governments and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. We may not be able to anticipate all types of security threats, and we may not be able to implement preventive measures effective against all such security threats. The techniques used by cyber criminals change frequently, may not be recognised until launched, and can originate from a wide variety of sources, including outside groups such as external service providers, organised crime affiliates, terrorist organisations or hostile foreign governments or agencies. If any such material system failure, accident or security breach were to occur and cause interruptions in our operations, it could result in a material disruption of our development programmes and our business operations, whether due to a loss of our trade secrets or other sensitive information or similar disruptions, as well as necessitating that we incur significant costs to address such failure, accident or security breach. To the extent that any such material system failure, accident or security breach were to result in a loss of, or damage to, our data or
59

Table of Contents
applications, or those of our third-party vendors and other contractors and consultants, or inappropriate disclosure of confidential or proprietary information, we could incur liability and reputational damage and the further development and commercialisation of our software could be delayed.
While we have implemented security measures designed to protect against security incidents, there can be no assurance that these measures will be effective. We take steps designed to detect, mitigate, and remediate vulnerabilities in our information systems (such as our hardware and/or software, including that of third parties upon which we rely). We may not, however, detect and remediate all such vulnerabilities including on a timely basis. Further, we may experience delays in deploying remedial measures and patches designed to address identified vulnerabilities. Vulnerabilities could be exploited and result in a security incident.
The costs related to significant security breaches or disruptions could be material and exceed the limits of the cybersecurity insurance we maintain against such risks. If the information technology systems of our third-party vendors and other contractors and consultants become subject to disruptions or security breaches, we may have insufficient recourse against such third parties and we may have to expend significant resources to mitigate the impact of such an event, and to develop and implement protections to prevent future events of this nature from occurring.
Furthermore, significant disruptions of our internal information technology systems or those of our third-party vendors and other contractors and consultants or security breaches could result in the loss, misappropriation, and/or unauthorised access, use, or disclosure of, or the prevention of access to, confidential information (including trade secrets or other intellectual property, proprietary business information and personal information), which could result in financial, legal, business and reputational harm to us. For example, any such event that leads to unauthorised access, use, or disclosure of personal information, including personal information regarding our customers or employees, could harm our reputation directly, compel us to comply with federal and/or state breach notification laws and foreign law equivalents, subject us to mandatory corrective action, and otherwise subject us to liability under laws and regulations that protect the privacy and security of personal information, which could result in significant legal and financial exposure and reputational damages that could potentially have an adverse effect on our business. Further, sophisticated cyber attackers (including foreign adversaries engaged in industrial espionage) are skilled at adapting to existing security technology and developing new methods of gaining access to organisations’ sensitive business data, which could result in the loss of sensitive information, including trade secrets. Additionally, actual, potential or anticipated attacks may cause us to incur increasing costs, including costs to deploy additional personnel and protection technologies, train employees and engage third-party experts and consultants.

Risks Related to our Employee Matters and Managing Growth
Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified personnel.
We are highly dependent on the research and development, clinical, financial, operational, scientific, software engineering and other business expertise of our executive officers, as well as the other principal members of our management, scientific, clinical and software engineering teams. Although we have entered into employment agreements with our executive officers, each of them may terminate their employment with us at any time. We do not maintain “key person” insurance for any of our executives or other employees.
In February 2024, our Chief Executive Officer was terminated and our Chief Scientific Officer was appointed as Interim Chief Executive Officer. The loss of the services of any of our other executive officers or other key employees could impede the achievement of our development and sales goals in our software business and the achievement of our research, development and commercialisation objectives in our drug discovery business. In either case, the loss of the services of our executive officers or other key employees could seriously harm our ability to successfully implement our business strategy. The Nominating and Corporate Governance Committee has instituted a search for a chief executive officer, but, replacing our chief executive officer or any other executive officers and key employees may be difficult and may take an extended period of time because of the limited number of individuals with the breadth of skills and experience required to successfully develop, gain regulatory approval of, and commercialise products in the life sciences industry.
Recruiting and retaining qualified scientific, clinical, manufacturing, accounting, legal and sales and marketing personnel, as well as software engineers and computational chemists, will also be critical to our success. In the technology industry, there is substantial and continuous competition for engineers with high levels of expertise in designing, developing and managing software and related services, as well as competition for sales executives, data scientists and operations personnel. Competition to hire these individuals is intense, and we may be unable to hire, train, retain or motivate these key personnel on acceptable terms given the competition among numerous biopharmaceutical and technology companies for similar personnel. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. In addition, we rely on consultants and advisors to assist us in formulating our research and development and commercialisation strategy and advancing our computational platform. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities that may limit their availability to us. If we are unable to continue to attract and retain high quality personnel, our ability to pursue our growth strategy will be limited and our business would be adversely affected.

We are pursuing multiple business strategies and expect to expand our development and regulatory capabilities, and as a result, we may encounter difficulties in managing our multiple business units and our growth, which could disrupt our operations.
Currently, we are pursuing multiple business strategies simultaneously, including activities in research and development and collaborative and internal drug discovery. We believe pursuing these multiple business strategies offers financial and operational synergies, but these diversified operations place increased demands on our limited resources. Furthermore, we expect to experience significant growth in the number of our employees and the scope of our operations, particularly in the areas of drug development, clinical and regulatory affairs. To manage our multiple business units and anticipated future growth, we must continue to implement and improve our managerial, operational and financial systems, expand our facilities and continue to recruit and train additional qualified personnel. Due to our limited financial resources and our management team’s limited attention and limited experience in managing a company with such anticipated growth, we may not be able to effectively manage our multiple business units and the expansion of our operations or recruit and train additional qualified personnel. The expansion of our operations may lead to significant costs and may divert our management and business development resources. In addition, to meet our obligations as a public company and to support our anticipated long-term growth, we will need to increase our general and administrative capabilities. Our management, personnel and systems may not be adequate to support this future growth. Any inability to manage our multiple business units and growth could delay the execution of our business plans or disrupt our operations and the synergies we believe currently exist between our business units. In addition, adverse developments in one of these business units may disrupt these synergies.

We may be unable to manage our rapid recent growth effectively, which could make it difficult to execute our business strategy.
Since our inception in 2012, we have experienced rapid growth. This growth has required our management to face complexities across all aspects of our business, including complexities associated with increased headcount, expansion of international operations, expansion of facilities, execution on new lines of business and implementations of appropriate systems and controls to grow the business. Our growth has required significant time and attention from our management, and placed strains on our operational systems and processes, financial systems and internal controls and other aspects of our business.
While we are currently focused on integrating existing employees into our company and progressing our drug candidates and technology platform to deliver against our corporate goals, we expect to increase headcount and to hire more specialised personnel as we grow our business in the future. We will need to continue to hire, train and manage additional qualified scientists, engineers, laboratory personnel and sales and marketing staff and improve and maintain our technology to properly manage our growth. We may also need to hire, train and manage individuals with expertise that is separate, supplemental or different from expertise that we currently have, and accordingly we may not be successful in hiring, training and managing such individuals. For example, if our new hires perform poorly, if we are unsuccessful in hiring, training, managing and integrating these new employees, or if we are not successful in retaining our existing employees, our business may be harmed. Improving our technology and processes have required us to hire and retain additional scientific, engineering, sales and marketing, software, manufacturing, distribution and quality assurance personnel. As a result, we have experienced rapid headcount growth from 17 employees as of January 1, 2018 to 483 employees as of December 31, 2023. Moreover, we expect that we will need to hire additional accounting, finance and other personnel in connection with our ongoing efforts to comply with the requirements of being a public company. A risk associated with experiencing this rate of growth, for example, is that we may face challenges integrating, developing and motivating our many new employees who are increasingly dispersed geographically.

Our rapid recent growth has, placed strains on our reporting systems and procedures. For example, in connection with the preparation and audits of our financial statements as of and for the years ended December 31, 2022 and 2023, material weaknesses were identified in our internal control over financial reporting, as described elsewhere in this “Risk Factors” section. To effectively manage our growth, we must continue to improve our operational and manufacturing systems and processes, our financial systems and internal controls and other aspects of our business and continue to effectively expand, train and manage our personnel. The time and resources required to improve our existing systems and procedures, implement new systems and procedures and to adequately staff such existing and new systems and procedures are uncertain, and failure to complete this in a timely and efficient manner could adversely affect our operations and negatively impact our business and financial.

If we fail to manage our technical operations infrastructure, our internal drug discovery team may experience service outages, and our new customers may experience delays in the deployment of our solutions.
We have experienced significant growth in the number of users and data that our operations infrastructure supports. We seek to maintain sufficient excess capacity in our operations infrastructure to meet the needs of all our customers and to support our internal drug discovery programmes. We also seek to maintain excess capacity to facilitate the rapid provision of new customer deployments and the expansion of existing customer deployments. In addition, we need to properly manage our technological operations infrastructure to support version control, changes in hardware and software parameters and the evolution of our solutions. However, the provision of new hosting infrastructure requires adequate lead-time. We have experienced, and may in the future experience, website disruptions, outages and other performance problems. These types of problems may be caused by a variety of factors, including infrastructure changes, human or software errors, viruses, security attacks, fraud, spikes in usage and denial of service issues. In some instances, we may not be able to identify the cause or causes of these performance problems within an acceptable period of time. If we do not accurately predict our infrastructure requirements, our existing customers may experience service outages that may subject us to financial penalties, financial liabilities and customer losses. If our operations infrastructure fails to keep pace with increased sales and usage, customers and our internal drug discovery team may experience delays in the deployment of our solutions as we seek to obtain additional capacity, which could adversely affect our reputation and adversely affect our revenues.

Increased labour costs, potential organisation of our workforce, employee strikes and other labour-related disruption may adversely affect our operations.
None of our employees are represented by a labour union or, other than as set out below, subject to a collective bargaining agreement. However, in Austria, we are subject to a government-mandated collective bargaining agreement, which sets minimum wage expectations and grants employees additional benefits beyond those required by the local labour code. We provide no assurance that our labour costs going forward will remain competitive for various reasons, such as: (i) our workforce may organise in the future and labour agreements may be put in place that have significantly higher labour rates and company obligations; (ii) our competitors may maintain significantly lower labour costs, thereby reducing or eliminating our comparative advantages vis-à-vis one or more of our competitors or the larger industry; and (iii) our labour costs may increase in connection with our growth.

Risks Related to International Operations
As a company headquartered and with operations outside of the United States, we are subject to economic, political, regulatory and other risks associated with international operations.
As a company headquartered in the United Kingdom and with operations in England, Scotland and Austria, our business is subject to risks associated with conducting business outside of the United States. Many of our suppliers and clinical trial relationships are located outside the United States. Accordingly, our future results could be harmed by a variety of factors, including:
economic weakness, including inflation, or political instability in certain non-U.S. economies and markets;
differing and changing regulatory requirements for product approvals;
differing jurisdictions could present different issues for securing, maintaining or obtaining freedom to operate in such jurisdictions;
potentially reduced protection for intellectual property and proprietary rights;
difficulties in compliance with different, complex and changing laws, regulations and court systems of multiple jurisdictions and compliance with a wide variety of foreign laws, treaties and regulations;
changes in non-U.S. regulations and customs, tariffs and trade barriers;
changes in currency exchange rates of the pound sterling, euro and the risk of the imposition of currency controls;
changes in a specific country’s or region’s political or economic environment;
trade protection measures, import or export licensing requirements or other restrictive actions by governments;
differing reimbursement regimes and price controls in certain non-U.S. markets;
negative consequences from changes in tax laws or practice;
compliance with tax, employment, immigration and labour laws for employees living or travelling abroad, including, for example, the variable tax treatment in different jurisdictions of options granted under our share option schemes or equity incentive plans;
workforce uncertainty in countries where labour unrest is more common than in the United States;
litigation or administrative actions resulting from claims against us by current or former employees or consultants individually or as part of class actions, including claims of wrongful terminations, discrimination, misclassification or other violations of labour law or other alleged conduct;
difficulties associated with staffing and managing international operations, including differing labour relations;
production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and
business interruptions resulting from geo-political actions, including war and terrorism, or natural disasters including earthquakes, typhoons, floods and fires and other natural disasters caused by climate change.

The United Kingdom’s withdrawal from the European Union may adversely impact our and our collaborators’ ability to obtain regulatory approvals of our drug candidates in the United Kingdom and European Union and may require us to incur additional expenses to develop, manufacture and commercialise our drug candidates in the United Kingdom and European Union.
We are headquartered in the United Kingdom. The United Kingdom formally exited the European Union, commonly referred to as Brexit, on January 31, 2020. Under the terms of its departure, the United Kingdom entered a transition period, or the Transition Period, during which it continued to follow all European Union rules, which ended on December 31, 2020. A trade and cooperation agreement, or the Trade and Cooperation Agreement, or TCA, that outlines the post-Transition Period trading relationship between the United Kingdom and the European Union, was agreed to in, and applied from, December 2020 and formally entered into force on May 1, 2021.
Since January 1, 2021 the United Kingdom has operated under a separate regulatory regime to the European Union. European Union laws regarding medicinal products only apply in respect of the United Kingdom to Northern Ireland (as set out in the Protocol on Ireland/Northern Ireland). The European Union laws that have been transposed into United Kingdom law through secondary legislation remain applicable. While the United Kingdom has indicated a general intention that new law regarding the development, manufacture and commercialisation of medicinal products in the United Kingdom will align closely with European Union law there are limited detailed proposals for future regulation of medicinal products. The TCA includes specific provisions concerning medicinal products, which include the mutual recognition of Good Manufacturing Practice, or GMP, inspections of manufacturing facilities for medicinal products and GMP documents issued (such mutual recognition can be rejected by either party in certain circumstances), but does not foresee wholesale mutual recognition of United Kingdom and European Union pharmaceutical legislation including in relation to batch testing and pharmacovigilance, which remain subject to further negotiation. The U.K. has unilaterally agreed to accept E.U. batch testing and batch release. However, the E.U. continues to apply E.U. laws that require batch testing and batch release to take place in the E.U. territory. This means that medicinal products that are tested and released in the U.K. must be retested and re-released when entering the E.U. market for commercial use. Therefore, there remains political and economic uncertainty regarding to what extent the regulation of medicinal products will differ between the United Kingdom and the European Union in the future.
Since a significant proportion of the regulatory framework in the United Kingdom applicable to our business and our drug candidates is derived from European Union Directives and Regulations, the development, manufacture, importation, approval and commercialisation of our drug candidates in the United Kingdom, and the European Union given our operations in the United Kingdom, will be materially affected by Brexit. Great Britain is no longer covered by the European Union’s procedures for the grant of marketing authorisations (Northern Ireland is covered by the centralised authorisation procedure and can be covered under the decentralised or mutual recognition procedures). A separate marketing authorisation granted by the U.K. competent authorities will be required to market drugs in Great Britain. It is currently unclear whether the Medicines and Healthcare products Regulatory Agency in the United Kingdom is sufficiently prepared to handle the increased volume of marketing authorisation applications that it is likely to receive.
On March 24, 2023, the Withdrawal Agreement Joint Committee adopted the U.K. Government and the European Commission political agreement on the “Windsor Framework”. The Framework is intended to revise the Northern Ireland Protocol. If the changes are adopted in the form proposed, medicinal products to be placed on the market in the U.K. will be authorized solely in accordance with U.K. laws. The implementation of the Windsor Framework would occur in stages, with new arrangements relating to the supply of medicinal products into Northern Ireland anticipated to take effect in 2025.

Any delay in obtaining, or an inability to obtain, any marketing approvals, as a result of Brexit or otherwise, would prevent us and our collaborators or delay us and our collaborators from commercialising our drug candidates in the United Kingdom and/or the EEA and restrict our ability to generate revenue and achieve and sustain profitability. Following Brexit, there is no pre-marketing authorisation orphan designation in Great Britain, instead an application for orphan designation is made at the same time as an application for marketing authorisation. Orphan designation in the United Kingdom (or Great Britain, depending on whether there is a prior centralised marketing authorisation in the EEA) following Brexit is based on the prevalence of the condition in Great Britain as opposed to the position prior to Brexit where prevalence in the European Union is the determinant. It is therefore possible that conditions that were designated as orphan conditions in the United Kingdom prior to Brexit will no longer be and that conditions are not currently designated as orphan conditions in the European Union will be designated as such in the United Kingdom, or Great Britain.
There is a degree of uncertainty regarding the overall impact that Brexit will have in the long-term on the development, manufacturing and commercialisation of pharmaceutical products, including the process to obtain regulatory approval in the United Kingdom for drug candidates and the award of exclusivities that are normally part of the European Union legal framework (for instance Supplementary Protection Certificates, Paediatric Extensions or Orphan exclusivity). Any further divergence between the regulatory environments in place in the European Union and the United Kingdom could lead to increased costs and delays in bringing drug candidates to market.
In addition, we may be required to pay taxes or duties or be subjected to other hurdles in connection with the trade of our drug candidates between the European Union and the United Kingdom, or we may incur expenses in establishing a manufacturing facility in the European Union to circumvent such hurdles, all of which may make our doing business in the European Union more difficult. If any of these outcomes occur, we may be forced to restrict or delay efforts to seek regulatory approval in the United Kingdom or the European Union for our drug candidates, or incur significant additional expenses to operate our business, which could significantly and materially harm or delay our ability to generate revenues or achieve profitability of our business.
As a result of Brexit or otherwise, other European countries may seek to conduct referenda with respect to their continuing membership with the European Union. Given these possibilities and others we may not anticipate, as well as the absence of comparable precedent, it is unclear what financial, regulatory and legal implications the withdrawal of the U.K. from the European Union will have in the long-term and how such withdrawal will affect us, and the full extent to which our business could be adversely affected.
Exchange rate fluctuations may materially affect our results of operations and financial condition.
Owing to the international scope of our operations, fluctuations in exchange rates, particularly between the pound sterling and the U.S. dollar, may adversely affect us. Although we are based in the United Kingdom, our CROs are located in a number of different geographic locations and we source research and development, manufacturing, consulting and other services from the United States and the European Union. Further, potential future revenue may be derived from abroad, particularly from the United States. As a result, our business and the price of our ADSs may be affected by fluctuations in foreign exchange rates not only between the pound sterling and the U.S. dollar, but also the euro, which may have a significant impact on our results of operations and cash flows from period to period.
Our ADSs trade in U.S. dollars. As a result of fluctuations in the exchange rate between the U.S. dollar and the pound sterling, the U.S. dollar equivalent of the proceeds that a holder of ADSs would receive upon the sale in the U.K. of any ordinary shares withdrawn from the depositary and the U.S. dollar equivalent of any cash dividends paid in pounds sterling on our ordinary shares represented by ADSs could also decline.

Risks Related to Ownership of Our Securities
Raising additional capital may cause dilution to our existing shareholders, restrict our operations or cause us to relinquish valuable rights.
We may seek additional capital through a combination of public and private equity offerings, debt financings, strategic partnerships and alliances and licensing arrangements. To the extent that we raise additional capital through the sale of equity, convertible debt securities or other equity-based derivative securities, your ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect your rights as holder of ADSs. Any indebtedness we incur would result in increased fixed payment obligations and could involve restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire or licence intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. Any debt or additional equity financing that we raise may contain terms that are not favourable to us or our shareholders. Furthermore, the issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may cause the market price of our ADSs to decline and existing shareholders may not agree with our financing plans or the terms of such financings. If we raise additional funds through strategic partnerships, collaborations and alliances and licensing arrangements with third parties, we may have to relinquish valuable rights to our intellectual property, technologies or our drug candidates, or grant licences on terms unfavourable to us.
The market price of our ADSs may be highly volatile, and you may not be able to resell your ADSs at or above your purchase price.
The market price of our ADSs is likely to be highly volatile. The stock market in general, and the market for biopharmaceutical companies in particular, has experienced extreme volatility that has often been unrelated to the operating performance of particular companies and the trading price of our equity securities may be volatile due to factors beyond our control. As a result of this volatility, you may not be able to sell your ADSs at or above your purchase price. The market price for our ADSs may be influenced by many factors, including:
our investment in, and the success of, our software solutions;
the success of our research and development efforts for our internal and/or partnered drug discovery programmes;
adverse results or delays in preclinical studies or clinical trials;
reports of adverse events in products similar or perceived to be similar to those we are developing or clinical trials of such products;

In the past, securities class action litigation has often been brought against a company following a decline in the market price of its securities. This risk is especially relevant for us because biopharmaceutical companies have experienced significant securities price volatility in recent years. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business. Broad market and industry factors may negatively affect the market price of our ADSs, regardless of our actual operating performance. Further, a decline in the financial markets and related factors beyond our control may cause the price of our ADSs to decline rapidly and unexpectedly.


If securities or industry analysts do not publish research or publish inaccurate or unfavourable research about our business, our ADS price and trading volume could decline.
The trading market for our ADSs will likely depend in part on the research and reports that securities or industry analysts publish about us or our business. We do not have any control over these analysts, and there can be no assurance that analysts will cover us, or provide favourable coverage. Securities or industry analysts may elect not to provide research coverage of our ADSs, and such lack of research coverage may negatively impact the market price of our ADSs. If one or more analysts downgrade our ADSs or change their opinion of our ADSs, our ADS price would likely decline. In addition, if one or more analysts cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our ADS price or trading volume to decline.

Concentration of ownership of our ordinary shares (including ordinary shares represented by ADSs) among our existing executive officers, directors and principal shareholders may prevent new investors from influencing significant corporate decisions.
Our executive officers, directors and current beneficial owners of five percent or more of our ordinary shares and their respective affiliates, in aggregate, beneficially own approximately 53% of our outstanding ordinary shares, based on the number of ordinary shares outstanding as of March 1, 2024 .
As a result, depending on the level of attendance at our general meetings of shareholders, these persons, acting together, would be able to significantly influence all matters requiring approval by our shareholders, including the election, re-election and removal of directors, any merger, scheme of arrangement, or sale of all or substantially all of our asset, or other significant corporate transactions and amendments to our articles of association.
68

Table of Contents
In addition, these persons, acting together, may have the ability to control the management and affairs of our company. Accordingly, this concentration of ownership may harm the market price of our ADSs and ordinary shares by:
delaying, deferring or preventing a change in control;
entrenching our management and/or the board of directors;
impeding a merger, scheme of arrangement, takeover or other business combination involving us; or
discouraging a potential acquirer from making a takeover offer or otherwise attempting to obtain control of us.
We may be required to repurchase for cash all, or to facilitate the purchase by a third party of all, of the ADSs of our company purchased by the Bill & Melinda Gates Foundation, or the Gates Foundation, in our October 2021 private placement if we default under the global access commitments agreement, which could have an adverse impact on us and limit our ability to make distributions to our shareholders.
In connection with the purchase by the Gates Foundation of 1,590,909 of our ADSs, concurrently with our initial public offering in a private placement that closed in October 2021, we entered into a Global Access Commitments Agreement, or the Global Access Agreement, pursuant to which we are required to take certain actions to support the Gates Foundation’s mission. In the event that we are in breach of certain related provisions of the Global Access Agreement, following a cure period, we may be required to repurchase for cash all, or to facilitate the purchase by a third party of all, of the ADSs purchased by the Gates Foundation in the concurrent private placement, at terms that may not be favourable to us. If this occurs, cash used for this purpose may adversely affect our liquidity, cause us to reduce expenditures in other areas of our business, or curtail our growth plans. If we do not have sufficient cash on hand to purchase the securities, we may have to seek financing alternatives in order to meet our obligations, and there is no certainty that financing would be available on reasonable terms or at all. During any period that we are unable to repurchase the ADSs held by the Gates Foundation or arrange for a third party to purchase such ADSs, we would not likely be allowed to pay dividends, repurchase the securities of any other shareholder or otherwise make any other distribution to any of our shareholders in connection with their securities. Therefore, meeting this purchase obligation, if necessary, could have a material adverse effect on our business and financial results.


Future sales, or the possibility of future sales, of a substantial number of our securities could adversely affect the price of the shares and dilute shareholders.
Sales of a substantial number of our ADSs in the public market could occur at any time, subject to certain restrictions described below. If our existing shareholders sell, or indicate an intent to sell, substantial amounts of our securities in the public market, the trading price of the ADSs could decline significantly. We have 125,702,396 outstanding ordinary shares (including ordinary shares represented by ADSs) as of December 31, 2023. As of December 31, 2023, holders of an aggregate of approximately 59,017,200 ordinary shares have rights, subject to conditions, to require us to file registration statements covering their shares or to include their shares in registration statements that we may file for ourselves or other shareholders, as well as to cooperate in certain public offerings of such ordinary shares. In addition, we have registered all ordinary shares that we may issue under our equity compensation plans and these ordinary shares can be freely sold in the public market upon issuance, subject to volume limitations applicable to affiliates.

Holders of ADSs are not treated as holders of our ordinary shares.
Holders of ADSs are not treated as holders of our ordinary shares, unless they withdraw the ordinary shares underlying their ADSs in accordance with the deposit agreement and applicable laws and regulations. The depositary is the holder of the ordinary shares underlying the ADSs. Holders of ADSs therefore do not have any rights as holders of our ordinary shares, other than the rights that they have pursuant to the deposit agreement.
Holders of ADSs may be subject to limitations on the transfer of their ADSs and the withdrawal of the underlying ordinary shares.
ADSs are transferable on the books of the depositary. However, the depositary may close its books at any time or from time to time when it deems expedient in connection with the performance of its duties. The depositary may refuse to deliver, transfer or register transfers of ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary think it is advisable to do so because of any requirement of law, government or governmental body or under any provision of the deposit agreement, or for any other reason, subject to the right of ADS holders to cancel their ADSs and withdraw the underlying ordinary shares. Temporary delays in the cancellation of your ADSs and withdrawal of the underlying ordinary shares may arise because the depositary has closed its transfer books, we have closed our transfer books, the transfer of ordinary shares is blocked to permit voting at a shareholders’ meeting or we are paying a dividend on our ordinary shares. In addition, ADS holders may not be able to cancel their ADSs and withdraw the underlying ordinary shares when they owe money for fees, taxes and similar charges and when it is necessary to prohibit withdrawals to comply with any laws or governmental regulations that apply to ADSs or to the withdrawal of ordinary shares or other deposited securities.

We are entitled to amend the deposit agreement and to change the rights of ADS holders under the terms of such agreement, or to terminate the deposit agreement, without the prior consent of the ADS holders.
We are entitled to amend the deposit agreement and to change the rights of the ADS holders under the terms of such agreement, without the prior consent of the ADS holders. We and the depositary may agree to amend the deposit agreement in any way we decide is necessary or advantageous to us or to the depositary. Amendments may reflect, among other things, operational changes in the ADS programme, legal developments affecting ADSs or changes in the terms of our business relationship with the depositary. In the event that the terms of an amendment are materially disadvantageous to ADS holders, ADS holders will only receive 30 days’ advance notice of the amendment, and no prior consent of the ADS holders is required under the deposit agreement. Furthermore, we may decide to direct the depositary to terminate the ADS facility at any time for any reason. For example, terminations may occur when we decide to list our ordinary shares on a non-U.S. securities exchange and determine not to continue to sponsor an ADS facility or when we become the subject of a takeover or a going-private transaction. If the ADS facility will terminate, ADS holders will receive at least 30 days’ prior notice, but no prior consent is required from them. Under the circumstances that we decide to make an amendment to the deposit agreement that is disadvantageous to ADS holders or terminate the deposit agreement, the ADS holders may choose to sell their ADSs or surrender their ADSs and become direct holders of the underlying ordinary shares, but will have no right to any compensation whatsoever.

ADS holders may not be entitled to a jury trial with respect to claims arising under the deposit agreement, which could result in less favourable outcomes to the plaintiff(s) in any such action.
The deposit agreement governing the ADSs representing our ordinary shares provides that, to the fullest extent permitted by law, holders and beneficial owners of ADSs irrevocably waive the right to a jury trial of any claim they may have against us or the depositary arising out of or relating to the ADSs or the deposit agreement.
If this jury trial waiver provision is not permitted by applicable law, an action could proceed under the terms of the deposit agreement with a jury trial. If we or the depositary opposed a jury trial demand based on the waiver, the court would determine whether the waiver was enforceable based on the facts and circumstances of that case in accordance with the applicable state and federal law. To our knowledge, the enforceability of a contractual pre-dispute jury trial waiver in connection with claims arising under the federal securities laws has not been finally adjudicated by the United States Supreme Court. However, we believe that a contractual pre-dispute jury trial waiver provision is generally enforceable, including under the laws of the State of New York, which govern the deposit agreement, by a federal or state court in the City of New York, which has non-exclusive jurisdiction over matters arising under the deposit agreement. In determining whether to enforce a contractual pre-dispute jury trial waiver provision, courts will generally consider whether a party knowingly, intelligently and voluntarily waived the right to a jury trial. We believe that this is the case with respect to the deposit agreement and the ADSs. It is advisable that you consult legal counsel regarding the jury waiver provision before entering into the deposit agreement.
If you or any other holders or beneficial owners of ADSs bring a claim against us or the depositary in connection with matters arising under the deposit agreement or the ADSs, including claims under federal securities laws, you or such other holder or beneficial owner may not be entitled to a jury trial with respect to such claims, which may have the effect of limiting and discouraging lawsuits against us and/or the depositary. If a lawsuit is brought against us and/or the depositary under the deposit agreement, it may be heard only by a judge or justice of the applicable trial court, which would be conducted according to different civil procedures and may result in different outcomes than a trial by jury would have had, including results that could be less favourable to the plaintiff(s) in any such action, depending on, among other things, the nature of the claims, the judge or justice hearing such claims and the venue of the hearing.
No condition, stipulation or provision of the deposit agreement or ADSs serves as a waiver by any holder or beneficial owner of ADSs or by us or the depositary of compliance with any substantive provision of the U.S. federal securities laws and the rules and regulations promulgated thereunder.

You will not have the same voting rights as the holders of our ordinary shares and may not receive voting materials in time to be able to exercise your right to vote.
Except as described in this annual report and the deposit agreement, holders of the ADSs will not be able to exercise voting rights attaching to the ordinary shares represented by the ADSs. Under the terms of the deposit agreement, holders of the ADSs may instruct the depositary to vote the ordinary shares underlying their ADSs. Otherwise, holders of ADSs will not be able to exercise their right to vote unless they withdraw the ordinary shares underlying their ADSs to vote them in person or by proxy in accordance with applicable laws and regulations and our articles of association. Even so, ADS holders may not know about a meeting far enough in advance to withdraw those ordinary shares. If we ask for the instructions of holders of the ADSs, the depositary, upon timely notice from us, will notify ADS holders of the upcoming vote and arrange to deliver our voting materials to them. Upon our request, the depositary will mail to holders a shareholder meeting notice that contains, among other things, a statement as to the manner in which voting instructions may be given. We cannot guarantee that ADS holders will receive the voting
71

Table of Contents
materials in time to ensure that they can instruct the depositary to vote the ordinary shares underlying their ADSs. A shareholder is only entitled to participate in, and vote at, the meeting of shareholders, provided that it holds our ordinary shares as of the record date set for such meeting and otherwise complies with our articles of association. In addition, the depositary’s liability to ADS holders for failing to execute voting instructions or for the manner of executing voting instructions is limited by the deposit agreement. As a result, holders of ADSs may not be able to exercise their right to give voting instructions or to vote in person or by proxy and they may not have any recourse against the depositary or us if their ordinary shares are not voted as they have requested or if their shares cannot be voted.

You may not receive distributions on our ordinary shares represented by the ADSs or any value for them if it is illegal or impractical to make them available to holders of ADSs.
The depositary for the ADSs has agreed to pay to you the cash dividends or other distributions it or the custodian receives on our ordinary shares or other deposited securities after deducting its fees and expenses, and any taxes. You will receive these distributions in proportion to the number of our ordinary shares your ADSs represent. However, in accordance with the limitations set forth in the deposit agreement, it may be unlawful or impractical to make a distribution available to holders of ADSs. We have no obligation to take any other action to permit distribution on the ADSs, ordinary shares, rights or anything else to holders of the ADSs. This means that you may not receive the distributions we make on our ordinary shares or any value from them if it is unlawful or impractical to make them available to you. These restrictions may have an adverse effect on the value of your ADSs.

Because we do not anticipate paying any cash dividends on our ADSs in the foreseeable future, capital appreciation, if any, will be your sole source of gains and you may never receive a return on your investment.
Under current English law, a company’s accumulated realised profits, to the extent they have not been previously utilised by distribution or capitalisation, must exceed its accumulated realised losses, to the extent they have not been previously written off in a reduction or reorganisation of capital duly made (as determined on a non-consolidated basis), before dividends can be declared and paid. Therefore, we must have distributable profits before declaring and paying a dividend. In addition, as a public limited company incorporated in England and Wales, we will only be able to make a distribution if the amount of our net assets is not less than the aggregate of our called-up share capital and undistributable reserves and if, and to the extent that, the distribution does not reduce the amount of those assets to less than that aggregate.
We have not paid dividends in the past on our ordinary shares. We intend to retain earnings, if any, for use in our business and do not anticipate paying any cash dividends in the foreseeable future. As a result, capital appreciation, if any, on our ADSs will be your sole source of gains for the foreseeable future, and you will suffer a loss on your investment if you are unable to sell your ADSs at or above your purchase price. Investors seeking cash dividends should not purchase our ADSs.

Claims of U.S. civil liabilities may not be enforceable against us.
We are incorporated under English law and have our registered office in England. Certain members of our board of directors and senior management are non-residents of the U.S., and all or a substantial portion of our assets and the assets of such persons are located outside the United States. As a result, it may not be possible to serve process on such persons or us in the U.S. or to enforce judgements obtained in U.S. courts against them or us based on civil liability provisions of the securities laws of the United States.
The United States and the United Kingdom do not currently have a treaty providing for recognition and enforcement of judgements in civil and commercial matters. Consequently, a final judgement for payment given by a court in the United States, whether or not predicated solely upon U.S. securities laws, would not automatically be recognised or enforceable in the United Kingdom. In addition, uncertainty exists as to whether the courts of England and Wales would entertain original actions brought in the United Kingdom against us or our directors or senior management predicated upon the securities laws of the United States or any state in the United States. Any final and conclusive monetary judgement for a definite sum obtained against us in U.S. courts would be treated by the courts of the United Kingdom as a cause of action in itself and sued upon as a debt at common law so that no retrial of the issues would be necessary, provided that certain requirements are met. Whether these requirements are met in respect of a judgement based upon the civil liability provisions of the U.S. securities laws, including whether the award of monetary damages under such laws would constitute a penalty, is an issue for the court making such a decision. If an English court gives judgement for the sum payable under a U.S. judgement, the English judgement will be enforceable by methods generally available for this purpose. These methods generally permit the English court discretion to prescribe the manner of enforcement.
As a result, U.S. investors may not be able to enforce against us or our senior management, board of directors or certain experts named herein who are residents of the United Kingdom or countries other than the United States any judgements obtained in U.S. courts in civil and commercial matters, including judgements under the U.S. federal securities laws.


Your right to participate in any future rights offerings may be limited, which may cause dilution to your holdings.
We may from time to time distribute rights to our shareholders, including rights to acquire our securities. However, we cannot make rights available to you in the United States unless the rights and the securities to which the rights relate are registered by us under the Securities Act or an exemption from the registration requirements is available. Also, under the deposit agreement, the depositary bank will not make rights available to you unless either both the rights and any related securities are registered under the Securities Act, or the distribution of them to ADS holders is exempted from registration under the Securities Act. We are under no obligation to file a registration statement with respect to any such rights or securities or to endeavour to cause such a registration statement to be declared effective. Moreover, we may not be able to establish an exemption from registration under the Securities Act. If the depositary does not distribute the rights, it may, under the deposit agreement, either sell them, if possible, or allow them to lapse. Accordingly, you may be unable to participate in our rights offerings and may experience dilution in your holdings.

We qualify as a foreign private issuer, which means we are exempt from a number of rules under the U.S. securities laws and are permitted to file less information with the SEC than U.S. domestic registrants.
We qualify as a “foreign private issuer,” as defined in the SEC rules and regulations and, consequently, we are not subject to all the requirements applicable to companies that are subject to the disclosure obligations for companies organised within the United States, or U.S. domestic registrants. For example, we are currently exempt from certain rules under the U.S. Securities Exchange Act of 1934, as amended, or the Exchange Act, that regulate disclosure obligations and procedural requirements related to the solicitation of proxies, consents or authorisations applicable to a security registered under the Exchange Act. In addition, our executive officers and directors are exempt from the reporting and “short-swing” profit recovery provisions of Section 16 of the Exchange Act and related rules with respect to their purchases and sales of our securities. Moreover, we are not required to file periodic reports and financial statements with the SEC as frequently or as promptly as U.S. domestic registrants and our financial statements do not have to be prepared in accordance with U.S. GAAP. Accordingly, there may be less publicly available information concerning our company than there is for U.S. domestic registrants and we expend fewer resources complying with our reporting obligations than do U.S. domestic registrants.
As a foreign private issuer, we will file an annual report on Form 20-F within four months of the close of each fiscal year ended December 31 and reports on Form 6-K relating to certain material events promptly after we publicly announce these events and disclosing our financial results. However, because of the above exemptions for foreign private issuers, our shareholders will not be afforded the same protections or information generally available to investors holding shares in U.S. domestic registrants.

As a foreign private issuer, we are not subject to certain Nasdaq corporate governance rules applicable to public companies organised in the United States.
We are entitled to rely on a provision in Nasdaq’s corporate governance rules that allows us to follow English corporate law with regard to certain aspects of corporate governance. This allows us to follow certain corporate governance practices that differ in significant respects from the corporate governance requirements applicable to U.S. public companies listed on Nasdaq, which may provide less protection to our shareholders than what is accorded to investors under the Nasdaq rules applicable to U.S. public companies.
We are entitled to deviate from the Nasdaq standards and rules applicable to the operations of our board of directors and related disclosures. We are not subject to Nasdaq Listing Rule 5605(b)(2) because English law does not require that independent directors regularly have scheduled meetings at which only independent directors are present. Similarly, English law does not require that we adopt a compensation committee or that such committee be fully comprised of independent directors. As a result, our compensation committee practice may vary from the requirements of Nasdaq Listing Rule 5605(d), which sets forth certain requirements as to the responsibilities, composition and independence of compensation committees. English law requires that we disclose information regarding compensation of our directors for services as a director of an undertaking that is our subsidiary undertaking and as a director of any other undertaking of which a director is appointed by virtue of our nomination (directly or indirectly) but not other third-party compensation of our directors or director nominees. As a result, our practice varies from the third-party compensation disclosure requirements of Nasdaq Listing Rule 5250(b)(3). Additionally, we are not subject to Nasdaq Listing Rule 5605(e) because, under English law, director nominees are not required to be selected or recommended for selection by either a majority of the independent directors or a nominations committee comprised solely of independent directors.
74

Table of Contents
Furthermore, English law does not have a regulatory regime for the solicitation of proxies applicable to us, thus our practice varies from the requirements of Nasdaq Listing Rule 5620(b) regarding the solicitation of proxies. In addition, we have opted out of shareholder approval requirements for the issuance of securities in connection with certain events such as the acquisition of stock or assets of another company, the establishment of or amendments to equity-based compensation plans for employees, a change of control of us and certain private placements. To this extent, our practice will vary from the requirements of Nasdaq Listing Rule 5635, which generally requires an issuer to obtain shareholder approval for the issuance of securities in connection with such events. In addition, while we have adopted a code of business conduct and ethics, English law does not require us to publicly disclose waivers from this code that have been approved by our board within four business days. As a result, our practice varies from the requirements for U.S. public companies pursuant to Nasdaq Listing Rule 5610. We expect to report any such waivers in the subsequent Annual Report on Form 20-F. Moreover, we are not required to comply with Regulation FD, which restricts the selective disclosure of material information, although we have voluntarily adopted a corporate disclosure policy substantially similar to Regulation FD. These exemptions and leniencies will reduce the frequency and scope of information and protections to which you may otherwise have been eligible in relation to a U.S. public company.
In accordance with our listing on Nasdaq, our audit committee is required to comply with the provisions of Section 301 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, and Rule 10A-3 of the Exchange Act, both of which are also applicable to U.S. public companies. Because we are a foreign private issuer, however, our audit committee is not subject to additional requirements applicable to U.S. public companies, including an affirmative determination that all members of the audit committee are “independent,” using more stringent criteria than those applicable to us as a foreign private issuer, subject to certain phase-in requirements permitted by Rule 10A-3 of the Exchange Act.

We are an “emerging growth company,” and the reduced disclosure requirements applicable to emerging growth companies may make our ADSs less attractive to investors.
We are an emerging growth company, or an EGC, and we will remain an EGC until the earlier to occur of (i) the last day of 2026; (ii) the last day of the fiscal year in which we have total annual gross revenues of at least $1.235 billion; (iii) the last day of the fiscal year in which we are deemed to be a “large accelerated filer,” under the rules of the SEC, which means the market value of our equity securities that is held by non-affiliates exceeds $700 million as of the prior June 30th; and (iv) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period. For so long as we remain an EGC, we are permitted and intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not EGCs. These exemptions include:
not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, or Section 404;
being permitted to provide only two years of audited financial statements in this annual report, in addition to any required unaudited interim financial statements, with correspondingly reduced “Item 5 – Operating and Financial Review and Prospects” disclosure;
reduced disclosure obligations regarding executive compensation; and
an exemption from the requirement to seek non-binding advisory votes on executive compensation or golden parachute arrangements.

75

Table of Contents
We may choose to take advantage of some, but not all, of the available exemptions. We have taken advantage of reduced reporting burdens in this annual report. In particular, we have not included all of the executive compensation information that would be required if we were not an EGC. We cannot predict whether investors will find our ADSs less attractive if we rely on certain or all of these exemptions. If some investors find our ADSs less attractive as a result, there may be a less active trading market for our ADSs and our ADS price may be more volatile.
In addition, the Jumpstart Our Business Startups Act, or the JOBS Act, provides that an EGC may take advantage of an extended transition period for complying with new or revised accounting standards. This allows an EGC to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have irrevocably elected not to avail ourselves of this extended transition period and, as a result, we will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies.
We incur costs as a result of operating as a company whose ADSs are publicly traded in the United States, and our management is and will be required to devote substantial time to new compliance initiatives.
The Sarbanes-Oxley Act and rules subsequently implemented by the SEC and Nasdaq have imposed various requirements on publicly traded companies of effective disclosure and financial controls and corporate governance practices. Our management and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations will increase our legal and financial compliance costs and will make some activities more time-consuming and costly. For example, we expect that these rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance.
Pursuant to Section 404, are required to furnish a report by our management on our internal control over financial reporting, including an attestation report on internal control over financial reporting issued by our independent registered public accounting firm. However, while we remain an EGC, we will not be required to include an attestation report on internal control over financial reporting issued by our independent registered public accounting firm. To achieve compliance with Section 404 within the prescribed period, we will be engaged in a process to document and evaluate our internal control over financial reporting, which is both costly and challenging. In this regard, we will need to continue to dedicate internal resources, potentially engage outside consultants and adopt a detailed work plan to assess and document the adequacy of internal control over financial reporting, continue steps to improve control processes as appropriate, validate through testing that controls are functioning as documented and implement a continuous reporting and improvement process for internal control over financial reporting. Despite our efforts, there is a risk we will not be able to conclude within the prescribed timeframe that our internal control over financial reporting is effective as required by Section 404. This could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements.

Table of Contents
We have identified material weaknesses in our internal control over financial reporting and may identify material weaknesses in the future or otherwise fail to maintain proper and effective internal controls, which may impair our ability to produce timely and accurate financial statements or prevent fraud. If we are unable to establish and maintain effective internal controls, shareholders could lose confidence in our financial and other public reporting, which would harm our business and the trading price of our ADSs.
A company’s internal control over financial reporting are processes designed by, or under the supervision of, a company’s principal executive and principal financial officers, or persons performing similar functions, and effected by a company’s board of directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with IFRS Accounting Standards issued by the International Accounting Standards Board (“IASB”). A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.
Section 404(a) of the Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act, requires that management assess and report annually on the effectiveness of our internal control over financial reporting and identify any material weaknesses in our internal control over financial reporting. Although Section 404(b) of the Sarbanes-Oxley Act requires our independent registered public accounting firm to issue an annual report that addresses the effectiveness of our internal control over financial reporting, we have opted to rely on the exemptions provided in the JOBS Act, and consequently, will not be required to comply with SEC rules that implement Section 404(b) until such time as we are no longer an emerging growth company.
In connection with this assessment, our management identified the following material weaknesses in our internal control over financing reporting as of December 31, 2023, both of which were identified in the course of preparing our consolidated financial statements for the year ended December 31, 2022:
1.We have not maintained effective process and controls throughout the period, including with respect to consistent review procedures within our financial statement close process to appropriately analyse, record and disclose accounting matters timely and accurately while maintaining appropriate segregation of duties.
2.We did not implement and maintain effective information technology general controls for information systems that are significant to the preparation of our financial statements, including controls to verify that conflicting duties were appropriately segregated within such systems in addition to controls over change management and programme development.
As a result of the material weaknesses described above, our management has concluded that our internal control over financial reporting was not effective at the reasonable assurance level as of December 31, 2023.
With the oversight of senior management and our audit committee, we continue to evaluate our internal control over financial reporting and are taking several remedial actions to further address the material weaknesses that has been identified, including:
We are in the process of implementing and operating the designed information technology general controls, including controls over the maintenance of appropriate segregation of duties,
We have engaged an external professional advisor with sufficient technical accounting expertise to assist us in the implementation and evaluation of internal controls over financial reporting, including the implementation and documentation of formal processes and controls to address the components of the COSO framework, which included formal accounting policies and procedures, maintaining evidence of control operation and segregating duties amongst accounting personnel,
77

Table of Contents
We engaged an external professional advisor with sufficient technical accounting expertise to assist us in finalizing the design of our financial control environment, including information technology general controls and controls over the maintenance of appropriate segregation of duties; and
We continue to recruit in order to ensure that we have the necessary expertise and bandwidth within the finance team to address the above material weaknesses including the hire of senior personnel with significant experience relating to the implementation and execution of information technology general controls, and we will enhance training of our personnel and clearly communicate control responsibilities.
However, as a result of the material weaknesses described above, management concluded our internal control over financial reporting was not effective at the reasonable assurance level as of December 31, 2023 and we have concluded that the material weaknesses in our internal control over financial reporting had not been fully remediated as of December 31, 2023.
The actions that we are taking are subject to ongoing review by our executive management and will be subject to audit committee oversight. Although we intend to complete this remediation process as quickly as practicable, we cannot at this time estimate how long it will take, and our initiatives may not prove to be successful in remediating the material weaknesses.
Were an independent assessment of the effectiveness of our internal controls over financial reporting to be performed, there is a risk that it could detect problems that our management’s assessment might not. Undetected material weaknesses in our internal controls over financial reporting could lead to financial statement restatements and require us to incur the expense of remediation. If we are unable to successfully remediate our identified material weakness, if we discover additional material weaknesses or if we otherwise are unable to otherwise determine on an ongoing basis that we have effective internal control over financial reporting, the accuracy and timing of our financial reporting may be adversely affected, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to applicable stock exchange listing requirements, investors may lose confidence in our financial reporting, and the price of our ADSs may decline as a result. We also could become subject to investigations by Nasdaq, the SEC or other regulatory authorities. Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.
We are subject to certain reporting requirements of the Exchange Act. Our disclosure controls and procedures are designed to reasonably assure that information required to be disclosed by us in reports we file or submit under the Exchange Act is accumulated and communicated to management, recorded, processed, summarised and reported within the time periods specified in the rules and forms of the SEC. We believe that any disclosure controls and procedures or internal controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. These inherent limitations include the realities that judgements in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorised override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements or insufficient disclosures due to error or fraud may occur and not be detected.

If we are (or one of our non-U.S. subsidiaries is) a “controlled foreign corporation,” or a CFC, there could be adverse U.S. federal income tax consequences to certain U.S. investors.
Generally, if a U.S. investor is treated as owning, directly, indirectly or constructively, at least 10% of either the total value or total combined voting power of our stock, such U.S. investor may be treated as a “United States shareholder” with respect to each CFC in our group, if any, for U.S. federal income tax purposes. A non-U.S. corporation will generally be a CFC for U.S. federal income tax purposes if U.S. shareholders own, directly, indirectly or constructively, more than 50% of either the total value or total combined voting power of the stock of such corporation. Because our group includes U.S. subsidiaries, our current non-U.S. subsidiaries and potentially any future newly formed or acquired non-U.S. subsidiaries will be treated as CFCs, regardless of whether we are treated as a CFC. A U.S. shareholder of a CFC may be required to annually report and include in its U.S. taxable income its pro rata share of “Subpart F income,” “global intangible low-taxed income” and investments of earnings in U.S. property, regardless of whether such CFC makes any distributions to its shareholders. Additionally, an individual that is a U.S. shareholder with respect to a CFC generally would not be allowed certain tax deductions or foreign tax credits that would be allowed to a U.S. shareholder that is a U.S. corporation. Failure to comply with CFC reporting obligations may also subject a U.S. shareholder to significant monetary penalties. We cannot provide any assurance that we will furnish to any U.S. shareholder information that may be necessary to comply with the reporting and tax paying obligations applicable under the CFC rules. U.S. investors should consult their tax advisors regarding the potential application of the CFC rules to their investment in our ordinary shares or ADSs.

If we are a “passive foreign investment company,” or a PFIC, for any taxable year, there could be adverse U.S. federal income tax consequences to U.S. investors.
Generally, we will be a PFIC for U.S. federal income tax purposes for any taxable year in which, after the application of certain look-through rules with respect to our subsidiaries, either (1) 75% or more of our gross income consists of passive income or (2) 50% or more of the average quarterly value of our assets consists of assets that produce, or are held for the production of, passive income (including cash and cash equivalents). For purposes of these tests, passive income generally includes, among other things, dividends, interest, gains from certain sales or exchanges of investment property and certain rents and royalties. If we are a PFIC for any taxable year during which a U.S. investor holds our shares, we will generally continue to be treated as a PFIC with respect to such U.S. investor for all succeeding taxable years during which such U.S. investor holds our shares, even if we cease to meet the threshold requirements for PFIC status. Such U.S. investor may be subject to adverse tax consequences, including ineligibility for any preferential tax rates on capital gains or on actual or deemed dividends, interest charges on certain taxes treated as deferred and additional reporting requirements. We cannot provide any assurance that we will furnish to such U.S. investor information that may be necessary to comply with the reporting and tax paying obligations applicable under the PFIC rules.
Based upon the value of our assets and the nature and composition of our income and assets, we expect that we will not be a PFIC for the taxable year ended December 31, 2023 though no assurance can be made in this regard. The determination of whether we are a PFIC is a fact-intensive determination made on an annual basis applying principles and methodologies that in some circumstances are unclear and subject to varying interpretation. For instance, for our current and future taxable years, the total value of our assets (including goodwill) for PFIC testing purposes may be determined in part by reference to the market price of our ordinary shares or ADSs from time to time, which may fluctuate considerably. If our market capitalisation declines while we hold a substantial amount of cash and cash equivalents for any taxable year, we may be a PFIC for that taxable year. Furthermore, under the income test, our status as a PFIC depends on the composition of our income for the relevant taxable year, which will depend on the
79

Table of Contents
transactions we enter into in the future and our corporate structure. The composition of our income and assets is also affected by how we spend the cash we raise in any offering. We currently do not generate revenues from the commercialisation of drug candidates and therefore we may be a PFIC for any taxable year in which we do not generate sufficient amounts of active income to offset our passive financing income. As a result, there can be no assurance that we will not be a PFIC for the current or any future taxable year and our U.S. counsel expresses no opinion with respect to our PFIC status for any prior, current or future taxable year. Even if we determine that we are not a PFIC for a taxable year, there can be no assurance that the Internal Revenue Service, or the IRS, will agree with our conclusion and that the IRS would not successfully challenge our position.
For further discussion of the PFIC rules and the adverse U.S. federal income tax consequences in the event we are classified as a PFIC, as well as certain elections that may be available to U.S. investors, see the section of this annual report titled “Item 10.E – Additional Information – Taxation – Material U.S. federal income tax considerations for U.S.investors.” U.S. investors should consult their tax advisors regarding the potential application of the PFIC rules to their investment in our ordinary shares or ADSs.

We may be unable to use net operating loss and tax credit carry forwards and certain built-in losses to reduce future tax payments or benefit from favourable U.K. tax legislation.
As a U.K. incorporated and tax resident entity, we are subject to U.K. corporate taxation. Due to the nature of our business, we have generated losses since inception and therefore have not paid any U.K. corporation tax. As of December 31, 2023, we had cumulative carryforward U.K. tax losses of £202.5 million. Subject to any relevant utilisation criteria and restrictions (including those that limit the percentage of profits that can be reduced by carried forward losses and those that can restrict the use of carried forward losses where there is a change of ownership of more than half the ordinary shares of the company and a major change in the nature, conduct or scale of the trade), we expect these to be eligible for carry forward and utilisation against future operating profits.
As a company that carries out extensive research and development, or R&D, activities, we seek to benefit from the U.K. R&D tax credit regime. In respect of accounting periods in which we qualify as a Small and Medium-sized Enterprise, or SME, and in which our qualifying R&D expenditure represents 40% (or, from April 1, 2024, 30%) or more of the total expenditure (meaning we also qualify as “R&D-intensive” during such accounting period), we may, under this regime, surrender the trading losses that arise from our R&D activities for a cash rebate of up to 26.97% of qualifying R&D expenditure. Accordingly, if we cease to qualify as an R&D-intensive SME in future, we will either cease to be able to claim cash rebates in respect of our R&D activities, or only be able to receive cash payments or other tax relief (under other provisions of the U.K. R&D tax credit regime) at a significantly lower rate than at present. Further, the regime’s rules are complex, and if a tax authority were to challenge or seek to disallow our claims (in whole or in part), for example by asserting that we do not (or the relevant expenditure does not) meet the technical conditions to be granted tax credits (or cash rebates), then such challenge or disallowance, if successful, could have a material impact on our cash-flow and financial performance. In addition, future changes to the U.K. R&D tax credit regime may mean that we no longer qualify for it or have a material impact on the extent to which we can make claims (or benefit from them).
We may benefit in the future from the United Kingdom’s “patent box” regime, which allows certain profits attributable to revenues from patented products (and other qualifying income) to be taxed at an effective rate of 10% by giving an additional tax deduction. We are the exclusive licensee or owner of several patent applications which, if issued, would cover our drug candidates, and accordingly, future upfront fees, milestone fees, product revenues and royalties could be eligible for this deduction. When taken in combination with the enhanced relief available on our R&D expenditures, we expect a long-term rate of corporation tax lower than the statutory rate to apply to us. If, however, there are unexpected adverse changes to the U.K. R&D tax credit regime or the “patent box” regime, or for any reason we are

unable to qualify for such advantageous tax legislation, or we are unable to use net operating loss and tax credit carryforwards and certain built-in losses to reduce future tax payments then our business, results of operations and financial condition may be adversely affected. This may impact our ongoing requirement for investment and the timeframes within which additional investment is required.

Changes and uncertainties in the tax system in the countries in which we have operations could materially adversely affect our financial condition and results of operations, and reduce net returns to our shareholders.
We conduct business globally and file income tax returns in multiple jurisdictions. Our consolidated effective income tax rate, and the tax treatment of our ADSs and ordinary shares, could be materially adversely affected by several factors, including: changing tax laws, regulations and treaties, or the interpretation thereof; tax policy initiatives and reforms under consideration or being implemented at national or international level (such as those related to the Base Erosion and Profit Shifting, or BEPS, Project, of the Organisation for Economic Co-Operation and Development, or OECD, or initiatives of the European Commission); the practices of tax authorities in jurisdictions in which we operate; the resolution of issues arising from tax audits or examinations and any related interest or penalties. Such changes may include (but are not limited to) the taxation of operating income, investment income, dividends received or (in the specific context of withholding tax) dividends paid, or the stamp duty or stamp duty reserve tax treatment of our ADSs or ordinary shares. For instance, the recently enacted Inflation Reduction Act imposes, among other rules, a 15% minimum tax on the book income of certain large corporations.
We are unable to predict what tax reform may be proposed or enacted in the future or what effect such changes would have on our business, but such changes, to the extent they are brought into tax legislation, regulations, policies or practices in jurisdictions in which we operate, could increase the estimated tax liability that we have expensed to date and paid or accrued on our financial statements, and otherwise affect our financial position, future results of operations, cash flows in a particular period and overall or effective tax rates in the future in countries where we have operations, reduce post-tax returns to our shareholders and increase the complexity, burden and cost of tax compliance.

Tax authorities may disagree with our positions and conclusions regarding certain tax positions, or may apply existing rules in an unforeseen manner, resulting in unanticipated costs, taxes or non-realisation of expected benefits.
A tax authority may disagree with tax positions that we take, which could result in increased tax liabilities. For example, His Majesty’s Revenue & Customs, or HMRC, the IRS or another tax authority could challenge our allocation of income by tax jurisdiction and the amounts paid between our affiliated companies pursuant to our intercompany arrangements and transfer pricing policies, including amounts paid with respect to our intellectual property development. Similarly, a tax authority could assert that we are subject to tax in a jurisdiction where we believe we have not established a taxable connection, often referred to as a “permanent establishment” under international tax treaties, and such an assertion, if successful, could increase our expected tax liability in one or more jurisdictions.
A tax authority may take the position that material income tax liabilities, interest and penalties are payable by us, in which case we expect that we might contest such assessment. Contesting such an assessment may be lengthy and costly and if we were unsuccessful in disputing the assessment, the implications could increase our anticipated effective tax rate, where applicable.

Shareholder protections found in provisions under the U.K. City Code on Takeovers and Mergers, or the Takeover Code, will not apply if our place of central management and control remains outside the United Kingdom (or the Channel Islands or the Isle of Man).
On September 22, 2021, Exscientia Limited was re-registered as a public limited company with the name Exscientia plc. Depending on meeting the jurisdictional criteria, the Takeover Code can be applicable to public limited companies incorporated in England and Wales. We believe that, as of the date of this document, our place of central management and control is not in the United Kingdom (or the Channel Islands or the Isle of Man) for the purposes of the jurisdictional criteria of the Takeover Code. Accordingly, we believe that we are currently not subject to the Takeover Code and, as a result, our shareholders are not currently entitled to the benefit of certain takeover offer protections provided under the Takeover Code, including the rules regarding mandatory takeover bids.
In the event that this changes, or if the interpretation and application of the Takeover Code by the Panel on Takeovers and Mergers, or Takeover Panel, changes (including changes to the way in which the Takeover Panel assesses the application of the Takeover Code to English companies whose securities are listed outside of the United Kingdom), the Takeover Code may apply to us in the future.
The Takeover Code provides a framework within which takeovers of companies are regulated and conducted. The following is a brief summary of some of the most important rules of the Takeover Code:
In connection with a potential offer, if following an approach by or on behalf of a potential bidder, the company is “the subject of rumour or speculation” or there is an “untoward movement” in the company’s share price, there is a requirement for the potential bidder to make a public announcement about a potential offer for the company, or for the company to make a public announcement about its review of a potential offer.
When a person or group of persons acting in concert (a) acquires, whether by a series of transactions over a period of time or not, interests in shares carrying 30% or more of the voting rights of a company (which percentage is treated by the Takeover Code as the level at which effective control is obtained) or (b) acquires an interest in any other shares which increases the percentage of shares carrying voting rights in which they are interested when they are already interested in shares which carry not less than 30% of the voting rights but do not hold shares carrying more than 50% of such voting rights, they must make a cash offer to all other shareholders at the highest price paid by them or any person acting in concert with them in the 12 months before the offer was announced.
When interests in shares carrying 10% or more of the voting rights of a class have been acquired by an offeror (i.e., a bidder) and any person acting in concert with it in the offer period (i.e., before the shares subject to the offer have been acquired) or within the previous 12 months, the offer must be in cash or be accompanied by a cash alternative for all shareholders of that class at the highest price paid by the offeror or any person acting in concert with them in that period. Further, if an offeror or any person acting in concert with them acquires any interest in shares during the offer period, the offer for the shares must be in cash or accompanied by a cash alternative at a price at least equal to the price paid for such shares during the offer period.
If after an announcement is made, the offeror or any person acting in concert with them acquires an interest in shares in an offeree company (i.e., a target) at a price higher than the value of the offer, the offer must be increased to not less than the highest price paid for the interest in shares so acquired.
An offeree company must appoint a competent independent adviser whose advice on the financial terms of the offer must be made known to all the shareholders, together with the opinion of the board of directors of the offeree company.
Special or favourable deals for selected shareholders are not permitted, except in certain circumstances where independent shareholder approval is given and the arrangements are regarded as fair and reasonable in the opinion of the financial adviser to the offeree.
All shareholders must be given the same information.
82

Table of Contents
Each document published in connection with an offer by or on behalf of the offeror or offeree must state that the directors of the offeror or the offeree, as the case may be, accept responsibility for the information contained therein.
Profit forecasts, quantified financial benefits statements and asset valuations must be made to specified standards and must be reported on by professional advisers.
Misleading, inaccurate or unsubstantiated statements made in documents or to the media must be publicly corrected immediately.
Actions during the course of an offer by the offeree company, which might frustrate the offer are generally prohibited unless shareholders approve these plans. Frustrating actions would include, for example, lengthening the notice period for directors under their service contract or agreeing to sell off material parts of the target group.
Stringent and detailed requirements are laid down for the disclosure of dealings in relevant securities during an offer, including the prompt disclosure of positions and dealing in relevant securities by the parties to an offer and any person who is interested (directly or indirectly) in 1% or more of any class of relevant securities.
Employees of both the offeror and the offeree company and the trustees of the offeree company’s pension scheme must be informed about an offer. In addition, the offeree company’s employee representatives and pension scheme trustees have the right to have a separate opinion on the effects of the offer on employment appended to the offeree board of directors’ circular or published on a website.


The rights of our shareholders may differ from the rights typically offered to shareholders of a U.S. corporation.
We are incorporated under English law. The rights of holders of ordinary shares and, therefore, certain of the rights of holders of ADSs, are governed by English law, including the provisions of the U.K. Companies Act 2006, or the Companies Act, and by our articles of association. These rights differ in certain respects from the rights of shareholders in typical U.S. corporations. See “Item 10.B – Additional Information – Memorandum and Articles of Association” in this annual report for a description of the principal differences between the provisions of the Companies Act applicable to us and, for example, the Delaware General Corporation Law relating to shareholders’ rights and protections.
The principal differences include the following:
under our articles of association, any resolution put to the vote of a general meeting must be decided exclusively on a poll. Under English law, it would be possible for our articles of association to be amended such that each shareholder present at a meeting has only one vote unless demand is made for a vote on a poll, in which case each holder gets one vote per share owned. Under U.S. law, each shareholder typically is entitled to one vote per share at all meetings;
under English law, subject to certain exceptions and disapplications, each shareholder generally has preemptive rights to subscribe on a proportionate basis to any issuance of ordinary shares or rights to subscribe for, or to convert securities into, ordinary shares for cash. Under U.S. law, shareholders generally do not have preemptive rights unless specifically granted in the certificate of incorporation or otherwise;
under English law and our articles of association, certain matters require the approval of 75% of the shareholders who vote (in person or by proxy) on the relevant resolution (or on a poll of shareholders representing 75% of the ordinary shares voting (in person or by proxy)), including amendments to the articles of association. This may make it more difficult for us to complete corporate transactions deemed advisable by our board of directors. Under U.S. law, generally only majority shareholder approval is required to amend the certificate of incorporation or to approve other significant transactions;

in the United Kingdom, takeovers may be structured as takeover offers or as schemes of arrangement. Under English law, a bidder seeking to acquire us by means of a takeover offer would need to make an offer for all of our outstanding ordinary shares/ADSs. If acceptances are not received for 90% or more of the ordinary shares/ADSs under the offer, under English law, the bidder cannot complete a “squeeze out” to obtain 100% control of us. Accordingly, acceptances of 90% of our outstanding ordinary shares/ADSs will likely be a condition in any takeover offer to acquire us, not 50% as is more common in tender offers for corporations organised under Delaware law. By contrast, a scheme of arrangement, the successful completion of which would result in a bidder obtaining 100% control of us, requires the approval of a majority of shareholders voting at the meeting and representing 75% of the ordinary shares (including those represented by ADSs) voting for approval;
under English law and our articles of association, shareholders and other persons whom we know or have reasonable cause to believe are, or have been, interested in our shares may be required to disclose information regarding their interests in our shares upon our request, and the failure to provide the required information could result in the loss or restriction of rights attaching to the shares, including prohibitions on certain transfers of the shares, withholding of dividends and loss of voting rights. Comparable provisions generally do not exist under U.S. law; and
the quorum requirement for a shareholders’ meeting is a minimum of two shareholders entitled to vote at the meeting and present in person or by proxy or, in the case of a shareholder which is a corporation, represented by a duly authorised representative. Under U.S. law, a majority of the shares eligible to vote must generally be present (in person or by proxy) at a shareholders’ meeting to constitute a quorum. The minimum number of shares required for a quorum can be reduced pursuant to a provision in a company’s certificate of incorporation or bylaws, but typically not below one-third of the shares entitled to vote at the meeting.

As an English public limited company, certain capital structure decisions will require shareholder approval, which may limit our flexibility to manage our capital structure.
On September 22, 2021, Exscientia Limited was re-registered as a public limited company with the name Exscientia plc. English law provides that our board of directors may only allot shares (or grant rights to subscribe for or convert any security into shares) with the prior authorisation of shareholders, such authorisation stating the aggregate nominal amount of shares that it covers and being valid for a maximum period of five years, each as specified in the articles of association or relevant ordinary shareholder resolution passed by shareholders at a general meeting. We have obtained authority from our shareholders to allot additional shares for a period of five years from September 15, 2021, which authorisation will need to be renewed upon expiration (i.e., at least every five years) but may be sought more frequently for additional five-year terms (or any shorter period).
English law also generally provides shareholders with preemptive rights when new shares are issued for cash. However, it is possible for the articles of association, or for shareholders to pass a special resolution at a general meeting, being a resolution passed by at least 75% of the votes cast, to disapply preemptive rights. Such a disapplication of preemptive rights may be for a maximum period of up to five years from the date of adoption of the articles of association, if the disapplication is contained in the articles of association, or from the date of the shareholder special resolution, if the disapplication is by shareholder special resolution but not longer than the duration of the authority to allot shares to which the disapplication relates. In either case, this disapplication would need to be renewed by our shareholders upon its expiration (i.e., at least every five years). We have obtained authority from our shareholders to disapply preemptive rights for a period of five years from September 15, 2021 which disapplication will need to be renewed upon expiration (i.e., at least every five years), but may be sought more frequently for additional five-year terms (or any shorter period).
84

Table of Contents
English law also generally prohibits a public company from repurchasing its own shares without the prior approval of shareholders by ordinary resolution, being a resolution passed by a simple majority of votes cast, and other formalities. Such approval may be for a maximum period of up to five years. See “Item 10.B – Additional Information – Memorandum and Articles of Association.”
Our articles of association provide that the courts of England and Wales are the exclusive forum for the resolution of all shareholder complaints other than complaints asserting a cause of action arising under the Securities Act and the Exchange Act, and that the U.S. District Court for the Southern District of New York will be the exclusive forum for the resolution of any shareholder complaint asserting a cause of action arising under the Securities Act or the Exchange Act.
Our articles of association provide that the courts of England and Wales are the exclusive forum for resolving all shareholder complaints (i.e., any derivative action or proceeding brought on behalf of us, any action or proceeding asserting a claim of breach of fiduciary duty owed by any of our directors, officers or other employees, any action or proceeding asserting a claim arising out of any provision of the Companies Act or our articles of association or any action or proceeding asserting a claim or otherwise related to the affairs of our company) other than shareholder complaints asserting a cause of action arising under the Securities Act or the Exchange Act, and that the U.S. District Court for the Southern District of New York is the exclusive forum for resolving any shareholder complaint asserting a cause of action arising under the Securities Act or the Exchange Act. In addition, our articles of association provide that any person or entity purchasing or otherwise acquiring any interest in our shares is deemed to have notice of and consented to these provisions.
This choice of forum provision may limit a shareholder’s ability to bring a claim in a judicial forum that it finds favourable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits. The enforceability of similar exclusive forum provisions (including exclusive federal forum provisions for actions, suits or proceedings asserting a cause of action arising under the Securities Act) in other companies’ organisational documents has been challenged in legal proceedings, and there is uncertainty as to whether courts would enforce the exclusive forum provisions in our articles of association. Additionally, our shareholders cannot waive compliance with the federal securities laws and the rules and regulations thereunder. If a court were to find either choice of forum provision contained in our articles of association to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could adversely affect our results of operations and financial condition. The courts of England and Wales and the U.S. District Court for the Southern District of New York may also reach different judgements or results than would other courts, including courts where a shareholder considering bringing a claim may be located or would otherwise choose to bring the claim, and such judgements may be more or less favourable to us than our shareholders.

General Risks
If our estimates or judgements relating to our critical accounting policies prove to be incorrect or financial reporting standards or interpretations change, our results of operations could be adversely affected.
The preparation of financial statements in conformity with IFRS requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We base our estimates on historical experience, known trends and events, and various other factors that we believe to be reasonable under the circumstances, as provided in “Item 5 – Operating and Financial Review and Prospects.” The results of these estimates form the basis for making judgements about the carrying values of assets and liabilities that are not readily apparent from other sources. Significant assumptions and estimates used in preparing our consolidated financial statements pertain to share-based payments provision, leases, recognition of revenue, loss-making contracts and deferred tax recoverability. Our results of operations may be adversely affected if our assumptions change or if actual circumstances differ from those in our assumptions, which could cause our results of operations to fall below the expectations of securities analysts and investors, resulting in a decline in the trading price of our ADSs.
Additionally, we regularly monitor our compliance with applicable financial reporting standards and review new pronouncements and drafts thereof that are relevant to us. As a result of new standards, changes to existing standards and changes in their interpretation, we might be required to change our accounting policies, alter our operational policies and implement new or enhance existing systems so that they reflect new or amended financial reporting standards, or we may be required to restate our published financial statements. Such changes to existing standards or changes in their interpretation may have an adverse effect on our reputation, business, financial position and profit.

A. History and Development of the Company
Exscientia was founded in 2012 as Exscientia Limited, a private company incorporated under the rules of Scotland. On June 29, 2021, Exscientia plc was incorporated under the laws of England and Wales as Exscientia Holdings Limited, with nominal assets and liabilities for the purpose of becoming the ultimate holding company for Exscientia AI Limited (formerly Exscientia Limited) and consummating the corporate reorganisation. Exscientia Inc., a Delaware corporation, is our wholly owned subsidiary. In August 2021, we acquired 100% of the outstanding share capital of Allcyte, a precision medicine biotechnology company. In October 2021, we completed the initial public offering of our ADSs on the Nasdaq Global Select Market. Our ADSs are traded under the symbol EXAI. Our ordinary shares are not listed.

B. Business Overview
We are a drug design company using artificial intelligence, or AI, and other technologies to efficiently design and develop differentiated medicines for diseases with high unmet patient need. The focus of our platform is to improve the probability of successful drug development by identifying and resolving likely points of failure using our AI design technology, translational systems and clinical modelling. We have demonstrated our platform can achieve design goals beyond current industry standards by advancing multiple development candidates with differentiated properties, four of which are currently in clinical trials. Our internal pipeline is primarily focused on oncology, but we also use our design capabilities with partners to expand our pipeline and generate income.
We believe many drug candidates fail due to predictable drug design issues. For more than a decade, we have been utilising AI to overcome these design issues and create better quality drug candidates. We also integrate novel experimental and automation systems in order to test and validate our AI-based simulations. Our closed loop of virtual design and physical experimentation is a critical advantage of our company because it allows our platform to learn quickly, to generate data that would not be available externally, and to be cost effective and reproducible.
87

Table of Contents
Our technology platform spans generative AI, active learning, machine learning, physics-based systems, large language models and many other predictive systems. However, the output of our technology is always a measurable drug. We have over 20 drug programmes advancing, including at least two with expected clinical milestones in 2024. Each drug we create needs to have a meaningful design advantage over known competitors that is expected to have clinical benefit and can be clearly measured.
Our lead internal candidate, a CDK7 inhibitor known as GTAEXS617 (‘617), is currently in a Phase 1/2 trial with initial data expected in the second half of this year. ‘617 was precision designed to manage the potential toxicities associated with CDK7 as well as optimising pharmacokinetics for maximising on-target efficacy.
We designed a PKC-theta inhibitor for Bristol Myers Squibb that they then in-licensed and are currently testing in Phase 1 clinical trials. Despite PKC-theta being a target of high interest, with more than a dozen companies having attempted to design compounds for the target, no competitor drug candidates have been sufficiently potent and selective and our candidate has the potential to be first-in-class. We have ongoing milestones and royalties associated with the programme.
We have two additional internal programmes in IND-enabling studies, respectively targeting LSD1 and MALT1. Both of these candidates were designed to mitigate known toxicities that have been seen in competitive programmes. By understanding the origin of these toxicities and designing against them we believe we have produced two candidates that will have an improved probability of success in clinical development.
Over time, we believe our transformational way of designing and developing drugs can change the industry's underlying pharmacoeconomic model, what we call 'shifting the curve'. We aim to demonstrate that it is simultaneously possible to improve probability of success through designing better quality drugs while also reducing investment requirements through improved technologies and process.

Key Achievements in 2023 and 2024 to Date
Pipeline Achievements

Our partner, Bristol Myers Squibb (BMY) initiated a Phase 1 clinical trial in February 2023 for EXS4318 (‘4318), a PKC-theta inhibitor that BMY in-licensed in 2021, with potential in inflammation and immunology.
In March 2023, two additional internal programmes entered IND-enabling studies. Each of the compounds, EXS74539 (‘539), our LSD1 inhibitor, and EXS73565 (‘565), our MALT1 inhibitor, are wholly owned by Exscientia with potential in haematology and oncology.
We initiated a Phase 1/2 trial, in mid-2023, to study GTAEXS617 (‘617) our CDK7 inhibitor partnered with GT Apeiron (GTA), in six different tumour types including ovarian cancer, pancreatic cancer, HR+ HER2- breast cancer, head and neck cancer, non-small cell lung cancer and colorectal cancer.

Partnership Achievements
We signed a new multi-target AI drug discovery collaboration with Merck KGaA, Darmstadt, Germany in September 2023. The collaboration is focused on the discovery of novel small molecule drug candidates across oncology, neuroinflammation and immunology.
In October 2023, we announced the achievement of the first milestone in our current Sanofi collaboration. This was for the first program initiated with Sanofi.
In December 2023, we announced that we had received a $2.3 million grant from Open Philanthropy to drive research on the host-interferon response as a pathway to treating and preventing pandemic influenza.
In December 2023, we added a new programme to our pre-existing collaboration with Sanofi, which was internally discovered by Exscientia. This program is not in an oncology indication and allows us to focus internally on high value oncology indications. Under the terms of the amended agreement, Exscientia is eligible for up to $45 million in upfront and preclinical milestone payments.

Platform Achievements
In March 2023, we announced a collaboration with Charité – Universitätsmedizin Berlin (Charité). This highlights the scalability of our primary patient tissue platform, as Charité will be able to utilise cloud-based AI to analyse samples that have been imaged onsite.
We opened our novel automated discovery laboratory in mid-2023. We believe that this integration of AI with automation has the potential to bring significant efficiencies to the drug design process.
In July 2023, we launched EXCYTE-1, a prospective observational study evaluating the potential of our functional precision medicine platform in ovarian cancer. This expands the scope of our precision medicine platform to solid tumours.
In the fourth quarter of 2023, we deployed large language models internally for the use of target hypothesis generation. These models, which are based on both public and proprietary datasets, have been integrated with our existing target identification infrastructure with the aim to enhance the productivity of our discovery platform.
In February 2024, we initiated EXCYTE-2, an observational clinical study in acute myeloid leukaemia, or AML, to investigate the relationship between ex vivo drug response, measured in primary blood or bone marrow samples using our functional precision medicine platform, and actual patient clinical response.

Our Strategy
Our strategy is to combine precision design, the deliberate placement of each atom in a compound, with integrated experiment, the ability to embed experimentation into our technology platform. This will enable us to design and develop better quality, balanced and differentiated medicines for patients with a higher probability of success in a faster and more efficient manner than industry average. By primarily focusing on the design of small molecules, we believe we can overcome complex issues that have impacted the success of other medicines. Our average time from initiating novel designs to first synthesis of the eventual drug candidate is approximately one year, and we typically synthesise fewer than a tenth of the number of compounds compared to conventional approaches.
Our approach aims to modernise the process of discovering and developing drugs, replacing the sequential, artisanal approach that currently dominates the industry, with an integrated, AI-first, patient-based learning system that is suited to the complexity of drug discovery.
We believe drugs often fail at the first step: design. By using precision design and integrated experiment, we believe we can accelerate the discovery of medicines and improve the probability of clinical success. We are driven to codify and optimise drug discovery, to move away from traditional sequential design, and instead leverage AI-based multi-parameter optimisation to scale the creation of precision engineered drugs.
Our innovative and advanced technologies and automation are designed to engineer better molecules than what has been accomplished with traditional methods. We believe our platform has the potential to fundamentally improve the probability of clinical and commercial success.

Precision Design
A drug’s potential utility is encoded into its chemical structure from the moment it is first designed. Before a compound is ever synthesised and tested, the placement of each atom and bond will have predetermined how it will interact with the incredible complexity of human biology and disease. The molecular structure of the compound determines its potency, selectivity, safety, absorption, dose requirements and manufacturability as well as many other features that define a drug product. We believe every drug candidate should be designed at the atomic level to drive optimal efficacy with minimal side effects.
Design from any data. High quality drugs need to satisfy dozens of diverse parameters, defined as a target product profile, or TPP. No single data type, such as a protein structure or cellular assay, can inform all of the parameters necessary to design a TPP. Our AI platform is data-agnostic, capable of modelling and exploiting diverse data types, including protein structures, high content screening, pharmacology and other data, through thousands of machine learning, physics-based and other predictive models. We have also developed proprietary tech-enabled laboratory capabilities to generate a wide variety of high-fidelity screening data (high content, biophysical, pharmacological and biochemical) and structural biology data to provide differentiated insights for our projects.
Our tech-driven design cycle. Our design philosophy is that every molecule should be designed by an algorithm. We unlock the creativity of AI through the use of reinforcement learning, deep learning and evolutionary algorithms to precisely design and select novel compounds that meet our design objectives. Our design cycle is as follows:

Table of Contents
Tech-driven Design Cycle2.jpg
Benefits of multi-parameter optimisation. Conventional drug discovery approaches focus on sequential design improvements, usually starting with target potency, then selectivity, then refining other properties, which often leads to suboptimal molecules . AI excels at multi-parameter optimisation, and our platform can design against more complex endpoints than have been conventionally possible. We have successfully designed molecules with very little starting data, with and without x-ray structure, and directly using high dimensional, high content data. We can also design small molecule bispecifics and drugs with complex phenotypic endpoints. We are not aware of any other design system that can incorporate such a breadth of data types into design.
Drug design is a learning problem. When designing truly innovative drugs, there will be insufficient information available at the start of the project and the right solution will almost certainly not already exist in big datasets or screening libraries. In other words, drug design is a learning — not a screening — problem. This is true for both novel targets, where no work has been done before, and established targets, where new approaches must be devised that are distinct from existing efforts. As we start to explore novel chemical spaces, we are likely to be at the limit of predictive power, or the domain of applicability, for current models. Our systems and models are designed to learn and evolve, which, like nature, allows them to find optimised solutions to problems.

Integrated Experiment
Proprietary data and experimentation. We believe the development of proprietary data is critical to designing and developing the most differentiated medicines. We differentiate from others in the field by bringing experimentation in-house and integrating this with our technology platform. We have developed capabilities in assay development (generating our own proteins and cell reagents) and also sourcing tissue directly from patients. By bringing experimentation in-house we have been able to increase the underlying quality of the data we generate. High quality, reproducible experimental data is what drives our machine learning models.
Maximising information gain with efficient data collection. Bringing experimentation in-house also highlighted to us the importance of efficiency in data collection. Our teams leverage active learning when designing experiments. This enables us to efficiently select the right compounds to synthesise and test, to maximise the information gained that will drive the validity of our models. This is in keeping with our drug design principles; each experiment is important and is done to enable a learning system - rather than to generate big, mostly redundant, datasets for screening. The virtual platform this enables can then be integrated with precision experiments.
Evolution of integrated experiment. We believe the integration of AI with automation can bring significant efficiencies to the drug design process and accelerate information gain. The use of automation for chemical synthesis and experimentation has the potential to simultaneously reduce cycle times and multiplex biological evaluation. With automation there is a potential to explore more complex biology. For example, we can now investigate new assay types, and evaluate multiple experimental elements simultaneously (increasing the throughput of analysis). We have identified key aspects of our drug design and experiment process that should be automated and opened our state of the art automation facility, in Milton Park, Oxfordshire, in June 2023. We believe this will further help us scale the generation of valuable molecular intellectual property.
Closing the loop between the virtual and physical. We believe that we are the first company to have built an automation facility that has the potential to close the loop between AI-led drug design and experimentation. This facility has capabilities in compound management, automated chemical synthesis, automated biological screening, and in time we expect that it will enable us to produce proteins and develop DMPK assays . We have also integrated modules of AI generative design, active learning and AI retrosynthesis/chemical reaction design with the hardware. We also believe that we are the first company to develop software that can orchestrate synthesis and experimentation in the physical world with the computational precision design of compounds, driving the integration between the virtual world and the real world. This means we could learn more at a faster rate.

Precision Medicine Platform
The patient is the best model. Current model systems, such as outgrowth cell lines, do not feature the complex interplay of cells and environment necessary to model drug action prior to clinical studies. They are subject to culture adaptation, genetic drift and do not recapitulate the complexity of human disease. We utilise primary patient samples, as the most disease relevant model system, not just to model drug actions but also to identify next-generation targets. We deploy a wide variety of technologies and AI-driven data analysis techniques, such as custom deep learning algorithms for analysing images of primary cells after ex vivo drug perturbation. We further collect orthogonal multi-omics data including single cell transcriptomics, genomics, epigenetics and proteomics, enabling us to both quantify drug action and understand disease state. In the first-ever prospective interventional study of its kind, EXALT-1, our platform predicted which therapy was to be most effective for late-stage haematological cancer patients based on drug activity in their own tissue samples. EXALT-1 demonstrated the real-world patient selection capabilities of our platform with 54% of patients following the platform’s recommendation demonstrating a clinical benefit of more than 1.3-fold enhanced progression-free survival (PFS) compared to their previous therapy.

EXALT1_Cancer Discovery.jpg

Scaling the patient platform. With our team of experts, we are able to scale our primary sample collection, understand the pre-analytics of primary samples, deploy state-of-the art and priority technologies with published proven clinical disruption and disease relevant results, as well as conduct robust analysis and interpretation of multi-omics data. Our experimental process is compatible with diverse tissue types and tumour indications including blood (leukaemias), lymph nodes (lymphoma), and solid tumour indications (tissues such as malignant pleural effusions and ascites and solid tissue samples). In July 2023, we launched EXCYTE-1, a prospective observational study in ovarian cancer, to evaluate our functional precision medicine platform. In February 2024, we initiated EXCYTE-2, an observational clinical study in acute myeloid leukaemia, to further evaluate this platform. Both studies investigate the relationship between ex vivo drug response as measured by our platform and clinical response of patients. In March 2023, we also announced a collaboration with one of Europe's largest university hospitals, Charité – Universitätsmedizin Berlin (Charité), in which the hospital will utilise our cloud-based AI to analyse samples onsite, highlighting the scalability of our platform in a real world environment.

Platform Philosophy
Model-driven adaptive learning, from target identification to the clinic. Our overarching philosophy is to use our proprietary datasets, precision design and integrated experiment to learn our way through the complex problems facing drug design and development today. More than 40% of the targets that we are investigating were generated using data from our proprietary databases (including phenotypic screens, primary patient samples and outputs from our knowledge graphs and large language models). We not only apply this approach to these key discovery areas but we are also taking the same approach to the clinic.We aim to apply both biological and statistical models from clinical and preclinical datasets to inform clinical trial design. This has the potential benefit of better defining the therapeutic index.

New Loop.jpg

Pipeline and Partnerships
Our purpose is to improve the lives of patients by creating highly differentiated medicines that solve significant unmet needs. We have already shown with the first eight announced development candidates from our platform that we can reduce time in discovery stages by 70%, as compared to industry estimates, which may translate to an 80% improvement in capital efficiency, potentially bringing new therapeutics to patients faster than ever before. We have a rapidly evolving discovery pipeline and will continue to progress molecules from here to our clinical pipeline.
Focused pipeline. Our platform allows us to rapidly discover new molecules. While the technology that drives our precision design approach is therapy area agnostic we have chosen to focus on oncology internally. Our biological, translational and clinical infrastructure is built around oncology, enabling us to concentrate our resources on the high value targets in this area. We look to leverage partnerships for other therapy areas in order to de-risk our business from both a financial and strategic point of view. For both partnered and internal programs, we go through a rigorous program selection process. This allows us to be thoughtful and critical in evaluating what to bring forward and what to partner. For example, in October 2023, we announced the reprioritisation of our pipeline to focus on differentiated, high value, oncology targets. This included the termination of the clinical programme supporting EXS21546, our A2AR antagonist compound.

Differentiated molecules. For all programs, internal or partnered, we look to design molecules that have differentiated properties to solve specific problems. Our precision design platform means we can focus on targets that either have historically not been tractable or had known design flaws.The table below describes our current pipeline candidates and the design flaw each candidate was created to solve:

GTAEXS617 (CDK7 Inhibitor): Phase 1/2; 50% ownership with GTA
CDK7_patient data.jpg
Unmet need/problem: The importance of cell cycle inhibitors has been established with CDK4/6 inhibitors, which generated approximately $9.0 billion in sales in 2022. Aberrant CDK7 overexpression is common in many cancer indications and associated with poor prognosis. CDK7 presents an opportunity to improve treatment outcomes over CDK4/6 inhibitors due to CDK7’s dual role in cell cycle and transcription.
Previous development efforts have exhibited significant side effects, possibly due to either a covalent binding mechanism of action or poor oral absorption. Current molecules in development for CDK7 are mostly covalent or have a long half life, which means there is the potential for meaningful on-target toxicity. In addition, the two reversible inhibitors in development are transporter substrate, which would be expected to lead to poorer absorption and higher gastrointestinal toxicity.
Our solution: Using our AI-driven process and multi-parameter optimisation as opposed to industry-standard sequential problem solving, we were able to identify potential design flaws with other CDK7 inhibitors in development, identify an improved target product profile and design a differentiated molecule.
We were able to first identify a molecule designed by our system and meeting all of our profile criteria after testing just 136 compounds. Our selective, non-covalent candidate meets multiple criteria, including high on-target potency and selectivity with improved absorption characteristics over competitors.
Better control of duration of inhibition with a predicted shorter half-life in humans and a non-covalent mechanism of action (MoA): Extended exposure would lead to increasing systemic toxicity in the absence of increasing efficacy.
Higher potency with better selectivity compared to other reversible compounds: Less off-target risks while maintaining on target potency.
Reduced efflux (transporter) issues: Issues with transporters will likely contribute to variable absorption and gastrointestinal issues from compound accumulation in the gastrointestinal (GI) tract.
Favourable oral bioavailability: CDK7 inhibition will lead to systemic on target toxicity if it remains at any site other than the tumour. Absorption variability can result in either supra- or sub-therapeutic dosing.

617_PK safety.jpg
Preclinically, we have shown that it is important to inhibit CDK7 for only 8-10 hours per 24 hour period. We have demonstrated that much longer exposure than this leads to significant body weight loss in mouse models.
Our precision medicine platform has enabled further understanding of the activity of ‘617 in different tumour types as a monotherapy. In a head-to-head ex vivo analysis conducted using primary patient material mainly from lung and ovarian cancer indications, ‘617 demonstrated a lower median toxicity towards immune cells but a tumor cell killing similar to other CDK7i candidates and a marketed CDK4/6i in NSCLC and ovarian cancer.



CDK7i_New charts2.jpg
Furthermore, our precision medicine platform is further deployed to study the combination potential between ‘617 and standard of care drugs/multiple targeted therapies.
98

Table of Contents
The platform is also being used to explore synergistic combinations and pharmacodynamics (PD) biomarkers. The graphic below shows these synergistic effects with current standard-of-care treatment options.

617-table.jpg

Ongoing Phase 1/2 trial. The ELUCIDATE trial is a multicentre, open-label, two-stage clinical trial to evaluate safety, pharmacokinetics, pharmacodynamics and efficacy of ‘617 administered orally as monotherapy and in combination with standard of care therapies. The company is enrolling patients with solid tumours who have advanced, recurrent or metastatic disease and have failed standard of care.
Both the monotherapy and combination therapy dose escalation portion of the trial will enrol patients across up to seven dose levels, depending on how many dose levels are needed to define the RP2D. The dose expansion phase of the trial will commence upon identification of the RP2D. The primary efficacy endpoint of the expansion phase is objective response rate (ORR).

EXS4318 (PKC-theta Inhibitor): Phase 1, in-licensed by BMY
Unmet need/problem: PKC-theta is an attractive immune modulating drug target; however, several large pharma companies have failed to design a small molecule with the required potency and selectivity against other closely related kinases. Previous pan-PKC inhibitors have had gastrointestinal and cardiovascular related adverse events in clinical trials. This could be linked to poor selectivity and suboptimal PK.
Our solution: Our platform designed a highly potent, highly selective next-generation immunomodulatory drug candidate within 11 months from the start of the design process, which was only the 150th molecule synthesised. The human dose prediction which is calculated by a composite of numerous pharmacological properties (including cross-species PK and potency) is very favourable. Our balanced candidate has demonstrated high on-target activity while maintaining high selectivity and favourable tolerability.

In February 2023, BMY announced that EXS4318 had entered a Phase 1 clinical trial in the United States.

EXS74539 (LSD1 Inhibitor): IND-enabling, wholly owned
LSD1_patient infographic.jpgUnmet need/problem: We believe LSD1 has potential in both AML and small cell lung cancer, or SCLC. These two indications have high unmet need with approximately45,000 patients diagnosed in the United States each year. LSD1 demethylates histones which play a critical role in regulating the expression of genes that suppress differentiation and drive the proliferation and survival of a number of tumour types. A reversible compound with a short half life is important to spare the key functions of the protein, while promoting the differentiation of cancer cells to quiescence and/or cell death. Penetrating the blood-brain-barrier would be an important characteristic for a treatment targeting small cell lung cancer, or SCLC, given that approximately 50% of patients with SCLC develop brain metastases. To date, other LSD1 inhibitors in development have failed to achieve the combination of appropriate pharmacokinetics, good brain penetrance and a reversible mechanism of action.
100

Table of Contents
Our solution: EXS74539 (‘539) is the first potent, selective, reversible and brain-penetrant LSD1 inhibitor. We used machine learning models to optimise multiple parameters including CNS penetrance, potency and ADMET properties. ‘539 achieves a design objective of suitable CNS penetration to target brain metastases, which are prevalent in certain cancer subtypes. The table below highlights the key properties of ‘539 versus other LSD1 inhibitors:
LSD1_CandidateTPP.jpg

In vivo
studies of ‘539 have shown favourable activity in SCLC xenograft models, with dose dependent inhibition of tumour growth. Studies have also demonstrated that ‘539 has a favourable profile with respect to absorption, distribution, metabolism, and excretion, or ADME, which are important molecule characteristics. ‘539 also has a shorter predicted human half-life than other LSD1 inhibitors currently in clinical trials. No safety concerns have been observed in preclinical studies conducted to date.
EXS73565 (MALT1 protease inhibitor): IND-enabling, wholly owned
Unmet need/problem: MALT1 is a protease crucial for activation of the NF-κB pathway which supports the uncontrolled proliferation of malignant T- and B-cells in haematological cancers. While treatment options are available for various haematologic malignancies, many do not fully meet the needs of their patients. As a result combinations will play an important role for these patients. Many of the current treatment options (such as BTK inhibitors) are known to cause drug-induced liver injuries, or DILIs. Hy’s law implies that therapies that may cause DILIs should not be paired with those that raise bilirubin levels. Scaffolds of other MALT1 inhibitors in the clinic significantly inhibit UGT1A1, an enzyme involved in the metabolism of bilirubin, often leading to dose-limiting toxicities in the clinic.
Our solution: Our precision design approach optimised the safety profile for agents targeting MALT1 while also generating potency and selectivity. In vivo studies of ‘565 have shown anti-tumour activity in mouse models and favourable pharmacokinetics both as monotherapy and in combination with ibrutinib (a BTK inhibitor). Toxicology studies have shown that ‘565 has an acceptable therapeutic index, with the ability to maintain high levels of potency, selectivity and safety benchmarks while avoiding meaningful inhibition of UGT1A1, which can lead to hyperbilirubinemia. The graphic below shows the product profile of ‘565, in particular the level of inhibition of UGT1A1, and how this compares to other MALT1 inhibitors.

Additional Pipeline Programs
We have multiple ongoing projects that range from target profiling to lead optimisation and we are continually initiating new projects across our business models, leveraging the capital efficiency that our platform brings. Using the first generation of our design platform we also developed additional drug candidates through a pilot "design as a service" (DaaS) programme with Sumitomo Pharma, including DSP-0038, currently in Phase 1 studies. Though we have no economic interest in these Sumitomo programmes, they do provide proof-of-concept of our capabilities to design molecules that can safely navigate regulatory, safety and toxicology requirements required to dose humans..

Our Collaborations
We currently have key collaboration agreements with Merck KGaA, Sanofi and BMY. Under each of these agreements, we perform all drug design work until a candidate has been selected. As with our internal oncology pipeline, we only advance programs with the highest probability of success that fulfil an unmet need. Partnerships enable us to extend our design capabilities to therapy areas of strategic fit for the partner. Our partnerships provide an additional avenue for our systems to learn and improve, offer a level of de-risking (both financial and strategic), while also enabling us to retain value in these candidates through the potential receipt of milestone and royalty payments from our partners.
Through our technologies and capabilities in automation, precision design and precision medicine, we strive to add substantial value for our partners in the screening of hard targets - precision design of drug candidates coupled with patient selection for clinical trials. We believe our novel technologies and capabilities should translate to future value creating partnerships.

Our Pharma Partners
Merck KGaA Logo.jpg
Merck KGaA, Darmstadt, Germany. In September 2023, we entered into a new collaboration with Merck KGaA. The multi-year collaboration utilises Exscientia’s AI-driven precision drug design and discovery capabilities while leveraging Merck KGaA, Darmstadt, Germany’s disease expertise in oncology and neuroinflammation, clinical development capabilities and global footprint. Under the terms of the agreement, we received $20 million (net of withholding taxes of $3.2 million which are expected to be received in the second half of 2024) from Merck KGaA, Darmstadt, Germany and will be eligible for discovery, development, regulatory and sales-based milestone payments of up to $674 million in aggregate, if all milestones for all three initial programmes are achieved. If Merck KGaA, Darmstadt, Germany commercialises a therapeutic from one of the initial targets of the collaboration, we will be eligible to receive tiered royalties on product sales ranging from mid-single-digits to low-double-digits.
BMY Logo.jpg
Bristol Myers Squibb (BMY). We and BMY are collaborating on a portfolio of multiple targets in oncology, autoimmunity, immunology and inflammation. The partnership began in 2019 with Celgene, and it expanded in 2021 directly with BMY following their acquisition of Celgene, with increasingly rewarding terms for Exscientia. BMY provides invaluable therapeutic area expertise, as well as a commitment to fund the development of molecules through the clinic. The second deal, coming just two years after the first, demonstrated the power of our platform to successfully deliver high quality drug candidates to BMY’s exacting preclinical candidate criteria. Together, these deals have already delivered $75 million in upfront payments. In August 2021, BMY exercised its option to in-licence an immune-modulating drug candidate we created under the first collaboration agreement, triggering a $20 million milestone payment that we collected in the third quarter of 2021. That candidate, EXS4318, is now in Phase 1 studies with the potential for Exscientia to receive milestones and royalties. Under the second BMY agreement, we could receive pre-clinical milestone payments of up to $125 million. The deal has a potential value of over $250 million per target in payments to us, including clinical and sales milestone payments, and provides us with royalties on each marketed asset. In October 2023, we mutually determined to prioritise certain projects and not to proceed with the development of others within the BMY collaboration.
Sanofi logo.jpg
Sanofi. In January 2022, we entered into a collaboration with Sanofi, pursuant to which we will use our AI-driven, end-to-end integrated platform to discover and validate up to 15 novel targets in the oncology and immunology therapeutic areas. We are collaborating with Sanofi to advance certain of these targets into small molecule inhibitor drug research projects and accelerating the identification of certain small molecule development candidates. In connection with this collaboration, we received an upfront cash payment of $100 million, and we have the potential to receive up to $5.2 billion in total milestone payments plus tiered royalties. In January 2023 an amendment was made to the collaboration to include a translational research plan for discovering and validating new targets. In July 2023, we made a second amendment to the agreement to vary certain terms with respect to the targets under the collaboration. In December 2023, Sanofi added an additional program to the collaboration that we originally discovered internally. Our 2022 collaboration is our second with Sanofi. The first collaboration, initiated in 2019, was for the design of a bispecific molecule that intentionally targeted multiple therapeutic targets and work under that collaboration has completed.

Our Non-profit Partners
Gates_logo.jpg
Bill & Melinda Gates Foundation. In December 2020, we were awarded a grant for $4.2 million from the Gates Foundation to develop treatments for malaria, tuberculosis and non-hormonal contraception. In June 2021, we received a further $1.5 million grant to expedite the optimisation of a new class of COVID-19 therapeutics created using our AI drug design platform. In September 2020, we further expanded our collaboration and entered into a four year agreement with the Gates Foundation to develop small molecule therapeutics that tackle the current coronavirus pandemic and help prepare for future pandemics. The expanded collaboration initially focused on developing broad-spectrum coronavirus agents (e.g., SARS-CoV-2 and its variants, MERS), including accelerating our lead programme, which targets the main protease, or Mpro, of SARS-CoV-2, the virus responsible for COVID-19. We have designed and synthesised promising compounds that have met our design objectives in in vitro studies. The collaboration has expanded to programs focusing on influenza and paramyxoviridae (e.g., Nipah). As part of this collaboration, the Gates Foundation purchased 1,590,909 of our ADSs in October 2021 in a private placement concurrent to our initial public offering, and we committed to provide $35.0 million in matching contributions over the course of four years, through operations and funding for third party activities.
Our Co-owned Collaborations
RallyBio_logo.jpg
Rallybio. In 2019, we entered into a co-development and co-ownership joint venture with Rallybio to investigate multiple areas of rare disease. There are 7,000 to 8,000 rare diseases, which affect over 30 million patients in the U.S. alone. And yet data on potential treatments for most of these diseases is sparse or non-existent. The deep learning approach of our platform can accelerate the discovery of novel treatments in knowledge-poor areas such as these. Rallybio’s vital therapeutic area and clinical knowledge allows us to enter a therapeutic area we would not otherwise attempt to tackle. Under this joint venture, we jointly select targets after assessment by our AI platform for biological pathway relevance and chemical druggability risks. We are driving the programme through completion of preclinical toxicology studies, and then Rallybio will progress the candidates through clinical trials and commercialisation, if any candidates are approved. We also have the option to explore molecules in non-rare disease indications, such as oncology. The partnership has delivered its first discovery candidates on a challenging target, ENPP1.
GT Apeiron Therapeutics_logo.jpg
GT Apeiron Therapeutics (GTA). In 2019, GT Healthcare, one of our investors, launched GTA and they immediately signed a deal with us to fund the discovery of novel cell cycle inhibitor compounds for the treatment of multiple oncology indications. The first candidate entered into IND enabling toxicology studies. Upon achievement of this milestone, we were eligible to receive an equity stake in GTA of approximately 13%. In July 2021, we jointly terminated this collaboration and entered into a joint operation and cost sharing arrangement with GTA for the development and commercialisation of multiple programmes, including the candidate developed under the deal executed in 2019. At execution of this new arrangement, we agreed to a 30% reduction in the equity stake we were eligible to receive under the original deal and paid GTA $2 million cash.

Our Team
We have gathered a team of world-class scientists and technologists that work collaboratively across the entire drug development process. They are led by a management team with deep industry experience. We are a global company, headquartered in Oxford, U.K. with sites in Milton Park (Oxfordshire, U.K.) Miami (FL, U.S.), Boston (MA, U.S.), Vienna (Austria) and Dundee (Scotland, U.K). We recruit talent from across the globe and expect to continue focussed hiring into our operations. As of December 31, 2023, our team consisted of 483 people represented by over 50 nationalities. Our pharmatech credentials are exemplified by the balance between technologists (35% of the company) and drug discovery scientists (53% of the company). Around 49% of our team works from our headquarters in Oxford, which includes a state-of-the-art lab completed in January 2021.
Our people have unique backgrounds but share a common goal of finding smarter and faster ways to discover and develop new drugs at the intersection of technology and experimental innovation.
Our Culture
We believe that people are our most important assets. We believe that our focus on creating a collaborative, entrepreneurial and innovative culture with a non-hierarchical approach is a key reason for our success.
We aim to inspire our employees to act as entrepreneurs in their areas of specialty and to continuously strive for innovation and excellence. Cultural fit is a key part of our recruiting process as we look to hire individuals who always want to challenge themselves, who take risks and who share our vision. We reward people who take initiative and regard failure as an opportunity to learn and inform improved approaches.
In addition to our success recruiting talent, we are focused on providing our people with opportunities to develop, take on additional responsibility and grow their careers. Internal talent growth is important as we fundamentally design drugs differently, and so institutional knowledge built upon the methodology developed by our founders is essential to help us design and develop drugs faster.
Diversity is an important area of focus. We are a global company, and our internationalism is reflected in our workforce which represents more than 50 nationalities from six continents. We will continue to work on internal initiatives and processes to ensure that Exscientia remains an inclusive and welcoming place to work for all while improving our gender, ethnicity and cultural diversity at all levels in the organisation.
Competition
The market for AI drug discovery and design is rapidly evolving, competitive and subject to changing technology. The technology utilised by our competitors vary in size, breadth and scope. We anticipate that we will face intense and increasing competition as technologies for drug discovery and design are developed.
We are applying AI, predictive models and advanced bioanalytics to rapidly design and develop precision drugs. Given the breadth of our technology, we compete within multiple categories of the pharmaceutical and biotechnology industries working to integrate AI and computational technologies to advance the speed and precision of drug discovery and development activities as well as other companies that are developing therapies targeting indications we are or may choose to pursue. As such, we face competition from major pharmaceutical companies, biotechnology companies, academic institutions, governmental agencies, consortiums and public and private research institutions, among others.

Many of our competitors, either alone or with their strategic collaborators, have substantially greater financial, technical and human resources than we do. Accordingly, our competitors may be more successful than we are in obtaining approval for treatments and achieving widespread market acceptance and may render our treatments obsolete or non-competitive. Mergers and acquisitions in the biotechnology and pharmaceutical industries may result in even more resources being concentrated among a smaller number of our competitors. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel, as well as in acquiring technologies complementary to our technology. Smaller or early-stage companies may also prove to be significant competitors.
We are aware of several companies using various technologies, including AI and other sophisticated computational tools, to accelerate drug development and improve the quality of identified drug candidates. These companies include Relay Therapeutics, AbCellera, Schrodinger, Recursion Pharmaceuticals, PathAI, Insitro, Valo Health, Cellarity, XtalPi, BenevolentAI, Absci and Atomwise.

Manufacturing
We do not own or operate manufacturing facilities for the production of any product candidates, nor do we currently have plans to develop our own manufacturing operations. We expect to rely on third-party contract manufacturers for all of our required raw materials, drug substance and finished drug product for the preclinical and clinical development of any development candidates we develop ourselves. As we grow, we will continue to re-evaluate production capabilities and may establish in-house manufacturing; however, we believe that all of our expected manufacturing requirements can be sourced from multiple vendors.

Intellectual Property
We design novel precision drugs and technology and seek to protect our innovations with a combination of patents and trade secrets, and for each novel technology or improvement we develop, we consider the appropriate course of intellectual property protection.
Our commercial success depends in part on our ability to obtain and maintain proprietary protection for drug candidates and any of our future drug candidates, novel discoveries, product development technologies and know how; to operate without infringing, misappropriating or otherwise violating the proprietary rights of others; and to prevent others from infringing, misappropriating or otherwise violating our proprietary rights. Our policy is to seek to protect our proprietary position by, among other methods, filing or in-licensing U.S. and foreign patents and patent applications related to our proprietary technology, inventions and improvements that are important to the development and implementation of our business. We also rely on trademarks, trade secrets, know-how, continuing technological innovation and potential in licensing opportunities to develop and maintain our proprietary position.

Patents
As of December 31, 2023, we owned and co-owned four issued U.S. patents, 14 pending U.S. patent applications, and over 150 pending foreign patent applications including unpublished foreign priority applications.
These patents and patent applications fall into 25 different patent families across up to 27 different jurisdictions worldwide. We generally rely upon trade secret protections for our AI technology platform as the platform includes hundreds of algorithms and more than 2,500 predictive models. From time to time, we file patent applications directed to aspects of our platform technologies. For example, we own a patent family which includes a granted U.S. patent, a granted European patent, a granted Indian patent, one pending U.S. continuation patent application, and a foreign patent application pending in Europe with claims covering certain aspects of our platform, which, if issued, are expected to expire in 2030, excluding any patent term adjustment or patent term extension. We also own an unpublished pending international patent application with claims directed to aspects of our platform, which, if issued, is expected to expire in 2043, excluding any patent term adjustment or patent term extension alongside three published international patent applications which have now entered the various national phases and which are expected to expire in 2041 and 2042 respectively, excluding any patent term adjustment or patent term extension.
With regards to patent protection on the molecules we design, we either solely own such filings, jointly own filings with our partners, or in some instances our partners solely own the patent filings. For example, we own and co-own five published international patent families directed to our novel compounds which include one granted U.S. patent application, four international patent applications, three of which have now entered the various national phases, one unpublished international application, three U.K./European priority applications and more than 100 foreign patent applications pending in such jurisdictions as Australia, Canada, China, Europe and Japan, which if issued, are expected to expire between 2039 and 2042.
The patent positions of companies like ours are generally uncertain and involve complex legal and factual questions. No consistent policy regarding the scope of claims allowable in patents in the field of biotechnology has emerged in the United States and in Europe, among other countries. Changes in the patent laws and rules, either by legislation, judicial decisions or regulatory interpretation in other countries may diminish our ability to protect our inventions and enforce our intellectual property rights, and more generally could affect the value of our intellectual property. In particular, our ability to stop third parties from making, using, selling, offering to sell, importing or otherwise commercialising any of our patented inventions, either directly or indirectly, will depend in part on our success in obtaining, defending and enforcing patent claims that cover our technology, inventions and improvements. With respect to company-owned intellectual property, we cannot be sure that patents will be granted with respect to any of our pending patent applications or with respect to any patent applications filed by us in the future, nor can we be sure that any of our existing patents or any patents that may be granted to us in the future will be commercially useful in protecting our platform and drug candidates and the methods used to manufacture them. Moreover, our issued patents and those that may issue in the future may not guarantee us the right to practice our technology in relation to the commercialisation of our platform’s drug candidates. The area of patent and other intellectual property rights in biotechnology is an evolving one with many risks and uncertainties, which may prevent us from commercialising our drug candidates and future drug candidates and practicing our proprietary technology.

107

Table of Contents
Our issued patents and those that may issue in the future may be challenged, narrowed, circumvented or invalidated, which could limit our ability to stop competitors from marketing related platforms or drug candidates or limit the length of the term of patent protection that we may have for our drug candidates, and future drug candidates, and platforms. In addition, the rights granted under any issued patents may not provide us with complete protection or competitive advantages against competitors with similar technology. Furthermore, our competitors may independently develop similar technologies that achieve similar outcomes but with different approaches. For these reasons, we may have competition for our drug candidates. Moreover, the time required for development, testing and regulatory review of our candidate products may shorten the length of effective patent protection following commercialisation. For this and other risks related to our proprietary technology, inventions, improvements, platforms and drug candidates, please see the section titled “Item 3.D – Key Information – Risk Factors – Risks Related to Our Intellectual Property.”
Our commercial success will also depend in part on not infringing upon the proprietary rights of third parties. It is uncertain whether the issuance of any third-party patent would require us to alter our development or commercial strategies for our products or processes, or to obtain licences or cease certain activities. Our breach of any licence agreements or failure to obtain a licence to proprietary rights that we may require to develop or commercialise our future products may have an adverse impact on us. If third parties prepare and file patent applications in the United States that also claim technology to which we have rights, we may have to participate in interference or derivation proceedings in the
U.S. Patent and Trademark Office, or USPTO, to determine priority of invention. For more information, please see “Item 3.D – Key Information – Risk Factors – Risks Related to Our Intellectual Property.”
From time to time we may file provisional patent applications in the United States. Provisional patent applications are not eligible to become issued patents until, among other things, we file a non-provisional patent application within 12 months of filing of one or more of our related provisional patent applications. If we do not timely file any non-provisional patent applications, we may lose our priority date with respect to our provisional patent applications and any patent protection on the inventions disclosed in our provisional patent applications. While we would intend to timely file non-provisional patent applications relating to any provisional patent applications we may file, we cannot predict whether any such patent applications will result in the issuance of patents that provide us with any competitive advantage.
The term of individual patents depends upon the legal term of the patents in the countries in which they are obtained. In most countries in which we file, the patent term is 20 years from the earliest date of filing a non-provisional patent application related to the patent. However, the actual protection afforded by a patent varies on a product-by-product basis, from country to country, and depends upon many factors, including the type of patent, the scope of its coverage, the availability of regulatory-related extensions, the availability of legal remedies in a particular country, and the validity and enforceability of the patent. A U.S. patent also may be accorded patent term adjustment, or PTA, under certain circumstances to compensate for delays in obtaining the patent from the USPTO. In some instances, such a PTA may result in a U.S. patent term extending beyond 20 years from the earliest date of filing a non-provisional patent application related to the U.S. patent. In addition, in the United States, the term of a U.S. patent that covers an FDA-approved drug may also be eligible for patent term extension, which permits patent term restoration as compensation for the patent term lost during the FDA regulatory review process.

Trademarks
As of December 31, 2023, our trademark portfolio comprises 77 trademark registrations or active trademark applications worldwide. Such portfolio includes 70 non-U.S. trademark registrations, 4 pending non-U.S. trademark applications and 3 pending U.S. trademark applications.
Trade Secrets. In addition to our reliance on patent protection for our inventions, drug candidates and programmes, we also rely on trade secrets, know-how, confidentiality agreements and continuing technological innovation to develop and maintain our competitive position. For example, some elements of proprietary assays, analytics techniques and processes, knowledge gained through clinical experience such as approaches to dosing and administration and management of patients, as well as computational-biological algorithms, and related processes and software, are based on unpatented trade secrets and know-how that are not publicly disclosed. Although we take steps to protect our proprietary information and trade secrets, including through contractual means with our employees, advisors and consultants, these agreements may be breached, and we may not have adequate remedies for any breach. In addition, third parties may independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets or disclose our technology. As a result, we may not be able to meaningfully protect our trade secrets. It is our policy to require our employees, consultants, outside scientific collaborators, sponsored researchers and other advisors to execute confidentiality agreements upon the commencement of employment or consulting relationships with us. These agreements provide that all confidential information concerning our business or financial affairs developed or made known to the individual or entity during the course of the party’s relationship with us is to be kept confidential and not disclosed to third parties except in specific circumstances. In the case of employees, the agreements provide that all inventions conceived of by the individual during the course of employment, and which relate to or are reasonably capable of being used in our current or planned business or research and development are our exclusive property. In addition, we take other appropriate precautions, such as physical and technological security measures, to guard against misappropriation of our proprietary technology by third parties. However, such agreements and policies may be breached, and we may not have adequate remedies for such breaches. For more information regarding the risks related to our intellectual property, see “Item 3.D – Key Information – Risk Factors – Risks Related to Our Intellectual Property.

Government Regulation
Government authorities in the United States, at the federal, state and local level, and in the European Union and other countries and jurisdictions, extensively regulate, among other things, the research, development, testing, manufacturing, quality control, approval, labelling, packaging, storage, record-keeping, promotion, advertising, distribution, post-approval monitoring and reporting, marketing and export and import of drugs, such as those we are developing. We, along with our vendors, third-party collaborators, CROs, and contract manufacturing organisations, or CMOs, will be required to navigate the various preclinical, clinical and commercial approval requirements of the governing regulatory agencies of the countries in which we wish to conduct studies or seek approval of our drug candidates. The processes for obtaining marketing approvals in the United States and in foreign countries and jurisdictions, along with subsequent compliance with applicable statutes and regulations and other regulatory authorities, require the expenditure of substantial time and financial resources.

U.S. Drug Development Process. In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or the FDCA, and its implementing regulations. Failure to comply with the applicable FDA or other requirements at any time during the drug development process, approval process or after approval may subject an applicant to administrative or judicial sanctions or other legal consequences. These sanctions could include, among other things, the FDA’s refusal to approve pending applications, suspension or revocation of an approval, a clinical hold, warning or untitled letters, product recalls or withdrawals, product seizures, total or partial suspensions of manufacturing or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties.
The process required by the FDA before a drug may be marketed in the United States generally involves the following:
completion of preclinical studies, including laboratory tests, animal studies and formulation studies, in accordance with FDA’s Good Laboratory Practice, or GLP, requirements and other applicable regulations;
submission to the FDA of an investigational new drug application, or IND, which must become effective before human clinical trials may begin and must be updated annually or when significant changes are made;
approval by an independent institutional review board, or IRB, or ethics committee at each clinical site before each trial may be initiated;
performance of adequate and well-controlled human clinical trials in accordance with Good Clinical Practice, or GCP, requirements to establish the safety and efficacy of the proposed drug for its intended use;
preparation and submission to the FDA of a New Drug Application, or NDA, after completion of all pivotal trials;
payment of user fees for FDA review of the NDA;
a determination by the FDA within 60 days of its receipt of an NDA to file the NDA for review;
satisfactory completion of an FDA advisory committee review, if applicable;
satisfactory completion of an FDA pre-approval inspection of the manufacturing facility or facilities at which the drug will be produced to assess compliance with current Good Manufacturing Practice, or cGMP, requirements to assure that the facilities, methods and controls are adequate to ensure and preserve the drug’s identity, strength, quality and purity;
potential FDA audit of the clinical trial sites that generated the data in support of the NDA to assess compliance with GCP requirements; and
FDA review and approval of the NDA to permit commercial marketing of the drug for particular indications for use in the United States.
Before testing any drug in humans, the product candidate must undergo rigorous preclinical testing. Preclinical studies include laboratory evaluations of chemistry, formulation and stability, as well as in vitro and animal studies to assess safety and in some cases to establish the rationale for therapeutic use. The conduct of preclinical studies is subject to federal and state regulations and requirements, including GLP requirements for safety and toxicology studies. Prior to beginning the first clinical trial with a drug candidate in the United States, we must submit an IND to the FDA. An IND is a request for authorisation from the FDA to administer an investigational drug to humans. The central focus of an IND submission is on the general investigational plan and the protocol(s) for clinical studies. Some preclinical testing may continue even after the IND is submitted. The IND also includes results of animal and in vitro studies assessing the toxicology, PK, pharmacology and pharmacodynamic characteristics of the product; chemistry, manufacturing and controls information; and any available human data or literature to support the use of the investigational product. An IND must become effective before human clinical trials may begin. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day time period, raises concerns or questions about the proposed clinical trial, including
110

Table of Contents
concerns that human research subjects will be exposed to unreasonable health risks. In such a case, the IND may be placed on clinical hold and the IND sponsor and the FDA must resolve any outstanding concerns or questions before the clinical trial can begin. Submission of an IND therefore may or may not result in FDA authorisation to begin a clinical trial.
Clinical trials involve the administration of the investigational drug to human subjects under the supervision of qualified investigators in accordance with GCP requirements, which include the requirement that all research subjects provide their informed consent for their participation in any clinical study. Clinical trials are conducted under protocols detailing, among other things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. A separate submission to the existing IND must be made for each successive clinical trial conducted during product development and for any subsequent protocol amendments. Furthermore, an independent IRB for each site proposing to conduct the clinical trial must review and approve the plan for any clinical trial before the clinical trial begins at that site and must monitor the clinical trial until it is completed. An IRB is charged with protecting the welfare and rights of trial participants and considers such items as whether the risks to individuals participating in the clinical trials are minimised and are reasonable in relation to anticipated benefits. The IRB also approves the informed consent form that must be provided to each clinical trial subject or his or her legal representative and must monitor the clinical trial until completed. FDA, the IRB or the sponsor may suspend or discontinue a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the drug has been associated with unexpected serious harm to patients. Some studies also include oversight by an independent group of qualified experts organised by the clinical study sponsor, known as a data safety monitoring board, which provides authorisation for whether or not a study may move forward at designated check points based on access to certain data from the study and may halt the clinical trial if it determines that there is an unacceptable safety risk for subjects or other grounds, such as no demonstration of efficacy. There are also requirements governing the reporting of ongoing clinical trials and clinical trial results to public registries. In the United States, information about applicable clinical trials, including clinical trial results, must be submitted within specific timeframes for publication on the www.clinicaltrials.gov website.
A sponsor who wishes to conduct a clinical trial outside of the United States may, but need not, obtain FDA authorisation to conduct the clinical trial under an IND. The FDA will accept a well-designed and well-conducted foreign clinical trial not conducted under an IND if the trial was conducted in accordance with GCP requirements, and the FDA is able to validate the data through an onsite inspection if deemed necessary.
Human clinical trials to evaluate therapeutic indications to support an NDA for marketing approval are typically conducted in three sequential phases that may overlap or be combined:
Phase 1: The drug candidate is initially introduced into healthy human subjects or patients with the target disease or condition. These studies are typically designed to test the safety, dosage tolerance, absorption, metabolism and distribution of the investigational product in humans, the side effects associated with increasing doses, and, if possible, to gain early evidence of effectiveness. In the case of some products for severe or life-threatening diseases, such as cancer, especially when the product may be too inherently toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients.
Phase 2: The drug candidate is administered to a limited patient population with a specified disease or condition to evaluate the preliminary efficacy, optimal dosages, dose tolerance and dosing schedule and to identify possible adverse side effects and safety risks. Multiple Phase 2 clinical trials may be conducted to obtain information prior to beginning larger and more expensive Phase 3 clinical trials.
111

Table of Contents
Phase 3: The drug candidate is administered to an expanded patient population to further evaluate dosage, to provide statistically significant evidence of clinical efficacy and to further test for safety, generally at multiple geographically dispersed clinical trial sites. These clinical trials are intended to establish the overall risk/benefit ratio of the investigational product and to provide an adequate basis for product approval. Generally, two adequate and well-controlled Phase 3 clinical trials are required by the FDA for approval of an NDA.
Post-approval trials, sometimes referred to as Phase 4 clinical trials, may be conducted after initial marketing approval. These trials are used to gain additional experience from the treatment of patients in the intended therapeutic indication and are commonly intended to generate additional safety data regarding use of the drug in a clinical setting. In certain instances, the FDA may mandate the performance of Phase 4 clinical trials as a condition of approval of an NDA.
During the development of a new drug, sponsors are given opportunities to meet with the FDA at certain points. These points may be prior to submission of an IND, at the end of Phase 2 and before an NDA is submitted. Meetings at other times may be requested. These meetings can provide an opportunity for the sponsor to share information about the data gathered to date, for the FDA to provide advice, and for the sponsor and the FDA to reach agreement on the next phase of development.
Sponsors typically use the meetings at the end of the Phase 2 trial to discuss Phase 2 clinical results and present plans for the pivotal Phase 3 clinical trials that they believe will support approval of the new drug.
Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of the drug candidate and finalise a process for manufacturing the drug candidate in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the drug candidate and, among other things, the manufacturer must develop methods for testing the identity, strength, quality and purity of the final drug product. In addition, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.
While the IND is active, progress reports summarizing the results of the clinical trials and nonclinical studies performed since the last progress report must be submitted at least annually to the FDA, and written IND safety reports must be submitted to the FDA and investigators fifteen days after the trial sponsor determines the information qualifies for reporting for serious and unexpected suspected adverse events, findings from other studies suggesting a significant risk to humans exposed to the same or similar drugs, findings from animal or in vitro testing suggesting a significant risk to humans, and any clinically important increased incidence of a serious suspected adverse reaction compared to that listed in the protocol or investigator brochure. The sponsor must also notify the FDA of any unexpected fatal or life-threatening suspected adverse reaction as soon as possible but in no case later than seven calendar days after the sponsor’s initial receipt of the information.
U.S. Review and Approval Process. Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, the results of product development, preclinical and other non-clinical studies and clinical trials, along with descriptions of the manufacturing process, analytical tests conducted on the chemistry of the drug, proposed labelling and other relevant information are submitted to the FDA as part of an NDA requesting approval to market the drug for one or more indications. Data may come from company-sponsored clinical trials intended to test the safety and effectiveness of a use of a drug, or from a number of alternative sources, including studies initiated by investigators. To support marketing approval, the data submitted must be sufficient in quality and quantity to establish the safety and effectiveness of the investigational drug to the satisfaction of the FDA. The submission of an NDA is subject to the payment of substantial user fees; a waiver of such fees may be obtained under certain
112

Table of Contents
limited circumstances. FDA approval of an NDA must be obtained before a drug may be marketed in the U.S.
The FDA reviews an NDA to determine, among other things, whether a drug is safe and effective for its intended use and whether its manufacturing is cGMP-compliant to assure and preserve the drug’s identity, strength, quality and purity. Under the goals and policies agreed to by the FDA under the Prescription Drug User Fee Act, or PDUFA, the FDA has a goal of ten months from the date of “filing” of a standard NDA for a new molecular entity to review and act on the submission, and six months from the filing date of an NDA subject to priority review. The FDA does not always meet its PDUFA goal dates for standard or priority NDAs, and the review process is often extended by FDA requests for additional information or clarification. The FDA conducts a preliminary review of all NDAs within the first 60 days after submission, before accepting them for filing, to determine whether they are sufficiently complete to permit substantive review. The FDA may request additional information rather than accept an NDA for filing. In this event, the NDA must be resubmitted with the additional information. The resubmitted application also is subject to review before the FDA accepts it for filing.
Further, under PDUFA, as amended, each NDA must be accompanied by a user fee. FDA adjusts the PDUFA user fees on an annual basis. Fee waivers or reductions may be available in certain circumstances, including a waiver of the application fee for the first application filed by a small business. Additionally, no user fees are assessed on NDAs for drugs designated as orphan drugs, unless the product also includes a non-orphan indication.
The FDA may refer an application for a drug to an advisory committee. An advisory committee is a panel of independent experts, including clinicians and other scientific experts, that reviews, evaluates and provides a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.
Before approving an NDA, the FDA will typically inspect the facility or facilities where the drug is manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the drug within required specifications. Additionally, before approving an NDA, the FDA will typically inspect one or more clinical sites to assure compliance with GCP and other requirements relating to the integrity of the clinical data submitted to the FDA. If the FDA determines that the application, manufacturing process or manufacturing facilities are not acceptable, it will outline the deficiencies in the submission and often will request additional testing or information. Notwithstanding the submission of any requested additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval.
After the FDA evaluates an NDA, including the advisory committee recommendation, if any, and inspection reports regarding the manufacturing facilities and clinical trial sites, the FDA may issue an approval letter or a Complete Response Letter. An approval letter authorises commercial marketing of the drug with prescribing information for specific indications. A Complete Response Letter indicates that the review cycle of the application is complete, and the application will not be approved in its present form. A Complete Response Letter usually describes the specific deficiencies in the NDA identified by the FDA, except that where the FDA determines that the data supporting the application are inadequate to support approval, the FDA may issue the Complete Response Letter without first conducting required inspections and/or reviewing proposed labelling. In issuing the Complete Response Letter, the FDA may require additional clinical data, such as an additional pivotal Phase 3 trial or other significant and time-consuming requirements related to clinical trials, nonclinical studies or manufacturing. If a Complete Response Letter is issued, the sponsor must resubmit the NDA, addressing all of the deficiencies identified in the letter, or withdraw the application or request a hearing. Even if such data and information are submitted, the FDA
113

Table of Contents
may decide that the NDA does not satisfy the criteria for approval. If and when the deficiencies are addressed to the FDA’s satisfaction, the FDA will typically issue an approval letter.
If regulatory approval of a product is granted, such approval will be granted for particular indications and may contain limitations on the indicated uses for which such product may be marketed. For example, the FDA may approve the NDA with a Risk Evaluation and Mitigation Strategy, or REMS, to ensure the benefits of the product outweigh its risks. A REMS is a safety strategy to manage a known or potential serious risk associated with a medicine and to enable patients to have continued access to such medicine by managing its safe use, and could include medication guides, physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimisation tools. The FDA also may condition approval on, among other things, changes to proposed labelling or the development of adequate controls and specifications. Once approved, the FDA may withdraw the product approval if compliance with pre- and post-marketing requirements is not maintained or if problems occur after the product reaches the marketplace. The FDA may also require one or more Phase 4 post-market studies and surveillance to further assess and monitor the product’s safety and effectiveness after commercialisation, and may limit further marketing of the product based on the results of these post-marketing studies. In addition, new government requirements, including those resulting from new legislation, may be established, or the FDA’s policies may change, which could impact the timeline for regulatory approval or otherwise impact ongoing development programmes.
Paediatric Information and Exclusivity. Under the Pediatric Research Equity Act, or PREA, as amended, certain NDAs and certain NDA supplements must contain data that can be used to assess the safety and efficacy of the drug candidate for the claimed indications in all relevant paediatric subpopulations and to support dosing and administration for each paediatric subpopulation for which the drug is safe and effective. The FDA may grant deferrals for submission of paediatric data or full or partial waivers. The FDCA requires that a sponsor who is planning to submit a marketing application for a drug candidate that includes a new active ingredient, new indication, new dosage form, new dosing regimen or new route of administration submit an initial Pediatric Study Plan, or PSP, within 60 days of an end-of-Phase 2 meeting or, if there is no such meeting, as early as practicable before the initiation of the Phase 3 or Phase 2/3 study. The initial PSP must include an outline of the paediatric study or studies that the sponsor plans to conduct, including study objectives and design, age groups, relevant endpoints and statistical approach, or a justification for not including such detailed information, and any request for a deferral of paediatric assessments or a full or partial waiver of the requirement to provide data from paediatric studies along with supporting information. The FDA and the sponsor must reach an agreement on the PSP. A sponsor can submit amendments to an agreed-upon initial PSP at any time if changes to the paediatric plan need to be considered based on data collected from preclinical studies, early phase clinical trials and/or other clinical development programmes. Unless otherwise required by regulation, PREA does not apply to a drug for an indication for which orphan designation has been granted, except that PREA will apply to an original NDA for a new active ingredient that is orphan-designated if the drug is a molecularly targeted cancer product intended for the treatment of an adult cancer and is directed at a molecular target that FDA determines to be substantially relevant to the growth or progression of a paediatric cancer.
A drug can also obtain paediatric market exclusivity in the United States. Paediatric exclusivity, if granted, adds six months to existing exclusivity periods and patent terms. This six-month exclusivity, which runs from the end of other exclusivity protection or patent term, may be granted based on the voluntary completion of a paediatric study in accordance with an FDA-issued “Written Request” for such a study.
114

Table of Contents
Orphan Drug Designation and Exclusivity. Under the Orphan Drug Act, the FDA may grant orphan drug designation, or ODD, to a drug or biologic intended to treat a rare disease or condition, defined as a disease or condition with either a patient population of fewer than 200,000 individuals in the United States, or a patient population greater of than 200,000 individuals in the United States when there is no reasonable expectation that the cost of developing and making available the drug or biologic in the United States will be recovered from sales in the United States of that drug or biologic. ODD must be requested before submitting an NDA or biologics licence application, or BLA. After the FDA grants ODD, the generic identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA.
If a product that has received ODD and subsequently receives the first FDA approval for a particular clinically active component for the disease for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications, including a full NDA or BLA, to market the same drug or biologic for the same indication for seven years from the approval of the NDA or BLA, except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity. Orphan drug exclusivity does not prevent the FDA from approving a different drug or biologic for the same disease or condition, or the same drug or biologic for a different disease or condition. Among the other benefits of ODD are tax credits for certain research and a waiver of the NDA or BLA application user fee.
A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received ODD. In addition, orphan drug exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition.
Expedited Development and Review Programmes. The FDA has a number of programmes intended to expedite the development or review of products that meet certain criteria. For example, new drugs are eligible for Fast Track designation if they are intended to treat a serious or life-threatening disease or condition and demonstrate the potential to address unmet medical needs for the disease or condition. Fast track designation applies to the combination of the product and the specific indication for which it is being studied. The sponsor of a fast track product has opportunities for more frequent interactions with the review team during product development, and the FDA may consider for review sections of the NDA on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the NDA, the FDA agrees to accept sections of the NDA and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the NDA.
Any product submitted to the FDA for approval, including a product with a fast track designation, may also be eligible for other types of FDA programmes intended to expedite development and review, such as priority review. A product is eligible for priority review if it is intended to treat a serious disease, and if approved, would provide a significant improvement in safety or effectiveness. The FDA will attempt to direct additional resources to the evaluation of an application for a new drug designated for priority review in an effort to facilitate the review. The FDA endeavours to review applications with priority review designations within six months of the filing date as compared to ten months for review of new molecular entity NDAs under its current PDUFA review goals.
In addition, a product may be eligible for accelerated approval. Drug candidates intended to treat serious or life-threatening diseases or conditions may be eligible for accelerated approval upon a determination that the product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity or prevalence of the condition and the availability or lack of alternative

treatments. As a condition of approval, the FDA may require that a sponsor of a drug receiving accelerated approval perform, in a diligent manner, adequate and well-controlled post-marketing confirmatory clinical trials to verify and describe the product’s clinical benefit. The FDA may withdraw approval of a drug or an indication approved under accelerated approval if, for example, the confirmatory trial fails to verify the predicted clinical benefit of the product. In addition, the FDA generally requires, unless otherwise informed by the agency, pre-approval of promotional materials for products being considered for accelerated approval, which could adversely impact the timing of the commercial launch of the product.
In addition, a new drug may be eligible to receive breakthrough therapy designation if the product is intended, alone or in combination with one or more other products, to treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the product may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. This designation includes all of the fast track designation programme features, as well as more intensive FDA interaction and guidance on an efficient development programme beginning as early as Phase 1, and FDA organisational commitment to expedited development, including involvement with senior managers and experienced review staff in a cross-disciplinary review, where appropriate. The breakthrough therapy designation is a distinct status from both accelerated approval and priority review, which can also be granted to the same drug if relevant criteria are met. If a product is designated as breakthrough therapy, the FDA will work to expedite the development and review of such drug.
Fast track designation, breakthrough therapy designation, priority review and accelerated approval do not change the standards for approval or the quality of evidence necessary to support approval, but may expedite the development or approval process. Even if a product qualifies for one or more of these programmes, the FDA may later decide that the product no longer meets the conditions for qualification or decide that the time period for FDA review or approval will not be shortened. We may explore some of these opportunities for our product candidates as appropriate.
Post-approval Requirements. Post-approval Requirements. Any products manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to record-keeping, reporting of adverse experiences, periodic reporting, product sampling and distribution and advertising and promotion of the product. After approval, most changes to the approved product, such as adding new indications or other labelling claims, are subject to prior FDA review and approval. There also are continuing, annual programme fees for any marketed products. Drug manufacturers and their subcontractors involved in the manufacture of approved products are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. Additionally, manufacturers and other parties involved in the drug supply chain for prescription drug products must also comply with product tracking and tracing requirements and for notifying FDA of counterfeit, diverted, stolen and intentionally adulterated products or products that are otherwise unfit for distribution in the United States. Changes to the manufacturing process are strictly regulated, and, depending on the significance of the change, may require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting requirements upon us and any third-party manufacturers that we may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance.

The FDA may withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labelling to add new safety information; imposition of post-market studies or clinical trials to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS programme. Other potential consequences include, among other things:
restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls;
fines, warning letters or untitled letters;
clinical holds on clinical studies;
refusal of the FDA to approve pending applications or supplements to approved applications, or suspension or withdrawal of product approvals;
product seizure or detention, or refusal to permit the import or export of products;
consent decrees, corporate integrity agreements, debarment or exclusion from federal healthcare programmes;
mandated modification of promotional materials and labelling and the issuance of corrective information;
the issuance of safety alerts, Dear Healthcare Provider letters, press releases and other communications containing warnings or other safety information about the product; or
injunctions or the imposition of civil or criminal penalties.

The FDA also may require post-marketing testing, known as Phase 4 testing, and surveillance to monitor the effects of an approved product. Discovery of previously unknown problems with a product or the failure to comply with applicable FDA requirements can have negative consequences, including adverse publicity, judicial or administrative enforcement, warning letters from the FDA, mandated corrective advertising or communications with doctors, and civil or criminal penalties, among others. Newly discovered or developed safety or effectiveness data may require changes to a product’s approved labelling, including the addition of new warnings and contraindications, and also may require the implementation of other risk management measures
The FDA closely regulates the marketing, labelling, advertising and promotion of drugs. A company can make only those claims relating to safety and efficacy that are approved by the FDA and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses. Failure to comply with these requirements can result in, among other things, adverse publicity, warning letters, corrective advertising and potential administrative, civil and criminal penalties. Physicians may prescribe, in their independent professional medical judgement, legally available products for uses that are not described in the product’s labelling and that differ from those tested by us and approved by the FDA. Physicians may believe that such off-label uses are the best treatment for many patients in varied circumstances. The FDA does not regulate the behaviour of physicians in their choice of treatments. The FDA does, however, restrict a manufacturer’s communications on the subject of off-label use of their products. The federal government has levied large civil and criminal fines against companies for alleged improper promotion of off-label use and has enjoined companies from engaging in off-label promotion. The FDA and other regulatory agencies have also required that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed. However, companies may share truthful and not misleading information that is otherwise consistent with a product’s FDA-approved labelling.

In addition, the distribution of prescription pharmaceutical products is subject to the Prescription Drug Marketing Act, or PDMA, which regulates the distribution of drugs and drug samples at the federal level, and sets minimum standards for the registration and regulation of drug distributors by the states. Both the PDMA and state laws limit the distribution of prescription pharmaceutical product samples and impose requirements to ensure accountability in distribution.
Patent Term Restoration and Extension. Depending upon the timing, duration and specifics of FDA approval of a sponsor’s product candidates, some of a sponsor’s U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly referred to as the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date and only those claims covering such approved drug product, a method for using it or a method for manufacturing it may be extended. The patent term restoration period generally is one-half the time between the effective date of an IND and the submission date of a NDA, plus the time between the submission date of an NDA and the approval of that application, less any time the sponsor did not act with due diligence during these periods. Only one patent applicable to an approved drug is eligible for the extension and the application for the extension must be submitted prior to the expiration of the patent. Moreover, a given patent may only be extended once based on a single product. The USPTO, in consultation with the FDA, reviews and approves the application for any patent term extension or restoration. Similar provisions are available in Europe and other foreign jurisdictions to extend the term of a patent that covers an approved drug. In the future, if and when our products receive FDA approval, we expect to apply for patent term extensions on patents covering those products, however there is no guarantee that the applicable authorities, including the FDA in the United States, will agree with our assessment of whether such extensions should be granted, and if granted, the length of such extensions. For more information regarding the risks related to our intellectual property, see “Item 3.D – Key Information – Risk Factors – Risks Related to Our Intellectual Property.”
Marketing Exclusivity. Market exclusivity provisions authorised under the FDCA can delay the submission or the approval of certain marketing applications. The FDCA provides a five-year period of non-patent marketing exclusivity within the United States to the first applicant to obtain approval of an NDA for a new chemical entity. A drug is a new chemical entity if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule or ion responsible for the action of the drug substance. During the exclusivity period, the FDA may not approve or even accept for review an abbreviated new drug application, or ANDA, or an NDA submitted under Section 505(b)(2), or a 505(b)(2) NDA, submitted by another company for another drug based on the same active moiety, regardless of whether the drug is intended for the same indication as the original innovative drug or for another indication, where the applicant does not own or have a legal right of reference to all the data required for approval. However, an application may be submitted after four years if it contains a certification of patent invalidity or non-infringement to one of the patents listed with the FDA by the innovator NDA holder.
118

Table of Contents
The FDCA also provides three years of marketing exclusivity for an NDA, or supplement to an existing NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application, for example for new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only the modification for which the drug received approval on the basis of the new clinical investigations and does not prohibit the FDA from approving ANDAs or 505(b)(2) NDAs for drugs containing the active agent for the original indication or condition of use. Five-year and three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to any preclinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness.
Regulation and Procedures Governing Approval of Medicinal Products in the E.U.. To market any product outside of the United States, a company also must comply with numerous and varying regulatory requirements of other countries and jurisdictions regarding quality, safety and efficacy and governing, among other things, clinical trials, marketing authorisation, commercial sales and distribution of products. Whether or not it obtains FDA approval for a product, an applicant will need to obtain the necessary approvals by the non-U.S. regulatory authorities before it can initiate clinical trials or marketing of the product in those countries or jurisdictions. Specifically, the process governing approval of medicinal products in the European Union generally follows the same lines as in the United States. It entails satisfactory completion of pharmaceutical development, nonclinical studies and adequate and well-controlled clinical trials to establish the safety and efficacy of the medicinal product for each proposed indication.
The requirements and process governing the conduct of clinical trials, product licensing, pricing and reimbursement may vary from country to country. In all cases, the clinical trials must be conducted in accordance with GCP and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki. Medicines used in clinical trials must be manufactured in accordance with cGMP.
Clinical Trials in the E.U.. Clinical trials of medicinal products in the European Union must be conducted in accordance with European Union and national regulations and the international council for harmonisation, or ICH, guidelines on GCP. Additional GCP guidelines from the European Commission, focusing in particular on traceability, apply to clinical trials of advanced therapy medicinal products. The sponsor must take out a clinical trial insurance policy, and in most European Union countries, the sponsor is liable to provide “no fault” compensation to any study subject injured in the clinical trial.
Prior to commencing a clinical trial, the sponsor must obtain a clinical trial authorisation from the national competent authority of the relevant Member State, and a positive opinion from an independent ethics committee. The application for a clinical trial authorisation must include, among other things, a copy of the trial protocol and an investigational medicinal product dossier containing information about the manufacture and quality of the medicinal product under investigation.
In the European Union, the Clinical Trials Regulation (E.U.) No 536/2014, which came into application on January 31, 2022, repealing and replacing the former Clinical Trials Directive 2001/20, or CTD, introduces a streamlined application procedure for the authorization of clinical trials in the E.U.. Accordingly, a single clinical trial application, or CTA, must be submitted via the EMA’s Clinical Trials Information System, for all E.U. Member States in which the sponsor is anticipating having trial sites. The CTR also establishes a harmonized two-part procedure for the assessment of CTAs and simplified reporting procedures for clinical trial sponsors, including in relation to adverse events. Individual E.U. Member States retain the power to authorize the conduct of clinical trials on their territory. Once the CTA is approved by an E.U. Member State, clinical trial development may proceed in that E.U. Member State.
119

Table of Contents
The extent to which on-going clinical trials will be governed by the CTR will depend on the duration of the individual clinical trial. For clinical trials in relation to which an application for approval was made on the basis of the CTD before January 31, 2023, the CTD will continue to apply on a transitional basis until January 31, 2025. By that date, all ongoing trials will become subject to the provisions of the CTR. The CTR will apply to clinical trials from an earlier date if the related clinical trial application was made on the basis of the CTR or if the clinical trial has already transitioned to the CTR framework before January 31, 2025.
The United Kingdom implemented the CTD, into national law through the Medicines for Human Use (Clinical Trials) Regulations 2004. The regulation of clinical trials in the United Kingdom therefore diverges from the European Union.
During the development of a medicinal product, the EMA and national competent authorities of E.U. Member States provide the opportunity for dialogue and guidance on the development programme. At the E.U. level, developers of medicinal products can as the EMA for scientific advice and protocol assistance at any stage of development and regardless of whether the medicinal product is eligible for the centralized authorization procedure or not. Assistance is given by the EMA’s Committee for Medicinal Products for Human Use, or CHMP, on the recommendation of the Scientific Advice Working Party. A fee is incurred with each scientific advice procedure. Advice from the EMA is provided by responding to specific questions concerning, quality aspects (manufacturing, chemical, pharmaceutical and biological testing of the medicine ), non-clinical testing (toxicological and pharmacological tests designed to show the activity of the medicine in the laboratory) and clinical aspects (appropriateness of studies in patients or healthy volunteers, selection of endpoints), methodological issues (statistical tests to use, data analysis, modelling and simulation), overall development strategy (conditional marketing authorization, bridging strategy for generics, safety database), significant benefit for maintaining orphan designation, and paediatric developments.
Marketing Authorisations. To market a new medicinal product in the European Economic Area, or EEA (comprising the 27 E.U. Member States plus Norway, Iceland and Liechtenstein), a company must obtain a marketing authorization, or MA. A marketing authorization application, or MAA, may be submitted to either the EMA, using the centralised procedure, or the competent authorities of E.U. Member States using the other procedures (decentralised procedure, mutual recognition procedure and national procedures) outlined below. An MA may only be granted to an applicant established in the EEA.
The centralised procedure provides for the grant of a single MA is issued by the European Commission through the centralised procedure, based on the scientific opinion of the CHMP, and is valid throughout the entire territory of the EEA. The centralised procedure is mandatory for certain types of products, such as (i) biotechnology medicinal products, (ii) orphan medicinal products, (iii) medicinal products containing a new active substance indicated for the treatment of HIV/AIDS, cancer, neurodegenerative disorders, diabetes, autoimmune and other immune dysfunctions and viral diseases and (iv) advanced-therapy medicinal products, i.e. gene therapy, somatic cell therapy or tissue-engineered medicines. The centralised procedure is optional for products containing a new active substance in therapeutic areas other than those listed as mandatory for the centralised procedure not yet authorised in the EEA, or for products that constitute a significant therapeutic, scientific or technical innovation or which are in the interest of public health in the EEA. Under the centralised procedure the maximum timeframe for the evaluation of an MAA by the EMA is 210 days, excluding clock stops, which provide the applicant with the time to provide additional written or oral information in response to questions asked by the CHMP. Therefore, clock stops may extend the timeframe of evaluation of an MAA considerably beyond 210 days. Where the CHMP gives a positive opinion, the EMA provides the opinion together with supporting documentation to the European Commission, which decides upon whether to grant an MA. If an MA is to be granted, it is usually issued within 67 days of receipt of the EMA’s opinion. Accelerated assessment might be granted by the CHMP in
120

Table of Contents
exceptional cases, when a medicinal product is expected to be of a major public health interest, particularly from the point of view of therapeutic innovation. The timeframe for the evaluation of an MAA under the accelerated assessment procedure is 150 days, excluding stop-clocks, but it is possible that the CHMP may revert to the standard time limit for the centralised procedure if it determines that the application is no longer appropriate to conduct an accelerated assessment.
The decentralised procedure is available for products not falling within the mandatory scope of the centralised procedure. An identical dossier is submitted to the competent authorities of each of the Member States in which the MA is sought, one of which is selected by the applicant as the Reference Member State, or RMS, to lead the evaluation of the regulatory submission. The competent authority of the RMS prepares a draft assessment report, a draft summary of the product characteristics, or SmPC, and a draft of the labelling and package leaflet as distilled from the preliminary evaluation, which are sent to the other EEA countries (referred to as the Concerned Member States) for their approval. The resulting assessment report is submitted to the Concerned Member States who, within 90 days of receipt, must decide whether to approve the assessment report and related materials. If the Concerned Member States raise no objections, based on a potential serious risk to public health, to the assessment, SmPC, labelling, or packaging proposed by the RMS, the RMS records the agreement, closes the procedure and informs the applicant accordingly. Each Concerned Member State is required to adopt a national decision to grant a national MA in conformity with the approved assessment report, SmPC and the labelling and package leaflet. If a Concerned Member State cannot approve the assessment report and related materials due to concerns relating to a potential serious risk to public health, disputed elements may be referred to the Heads of Medicines Agencies’ Coordination Group for Mutual Recognition and Decentralised Procedures – Human, or CMDh, for review. The subsequent decision of the European Commission is binding on all E.U. Member States.
Where a product has already been authorised for marketing in an EEA country, the granted national MA can be used for mutual recognition in other EEA countries through the mutual recognition procedure.
National MAs, which are issued by a single competent authority of EEA countries and only cover their respective territory, are also available for products not falling within the mandatory scope of the centralised procedure.
Under the procedures described above, before granting the MA, the European Commission or the competent authority(ies) of the EEA country(ies) prepare an assessment of the risk-benefit balance of the product against the scientific criteria concerning its quality, safety and efficacy.
Innovative products that target an unmet medical need and are expected to be of major public health interest may be eligible for a number of expedited development and review programs, such as the Priority Medicines, or PRIME, scheme, which provides incentives similar to the breakthrough therapy designation in the U.S. PRIME is a voluntary scheme aimed at enhancing the EMA’s support for the development of medicinal products that target unmet medical needs. Eligible products must target conditions for which there is an unmet medical need (there is no satisfactory method of diagnosis, prevention or treatment in the E.U. or, if there is, the new medicinal product will bring a major therapeutic advantage) and they must demonstrate the potential to address the unmet medical need by introducing new methods of therapy or improving existing ones. Benefits accrue to sponsors of product candidates with PRIME designation, including but not limited to, early and proactive regulatory dialogue with the EMA, frequent discussions on clinical trial designs and other development program elements, and potentially accelerated MAA assessment once a dossier has been submitted.
In the E.U., a “conditional” MA may be granted in cases where all the required safety and efficacy data are not yet available. The European Commission may grant a conditional MA for a medicinal product if it is demonstrated that all of the following criteria are met: (i) the benefit-risk balance of the medicinal product is positive; (ii) it is likely that the applicant will be able to provide comprehensive data post-
121

Table of Contents
authorization; (iii) the medicinal product fulfils an unmet medical need; and (iv) the benefit of the immediate availability to patients of the medicinal product is greater than the risk inherent in the fact that additional data are still required. The conditional MA is subject to conditions to be fulfilled for generating the missing data or ensuring increased safety measures. It is valid for one year and must be renewed annually until all related conditions have been fulfilled. Once any pending studies are provided, the conditional MA can be converted into a traditional MA. However, if the conditions are not fulfilled within the timeframe set by the EMA and approved by the European Commission, the MA will cease to be renewed.
An MA may also be granted “under exceptional circumstances” where the applicant can show that it is unable to provide comprehensive data on efficacy and safety under normal conditions of use even after the product has been authorized and subject to specific procedures being introduced. These circumstances may arise in particular when the intended indications are very rare and, in the state of scientific knowledge at that time, it is not possible to provide comprehensive information, or when generating data may be contrary to generally accepted ethical principles. Like a conditional MA, an MA granted in exceptional circumstances is reserved to medicinal products intended to be authorized for treatment of rare diseases or unmet medical needs for which the applicant does not hold a complete data set that is required for the grant of a standard MA. However, unlike the conditional MA, an applicant for authorization in exceptional circumstances is not subsequently required to provide the missing data. Although the MA “under exceptional circumstances” is granted definitively, the risk-benefit balance of the medicinal product is reviewed annually, and the MA will be withdrawn if the risk-benefit ratio is no longer favourable.
Data and Market Exclusivity in Europe. Under Regulation (EC) No 726/2004/EC and Directive 2001/83/EC (each as amended), the EEA has adopted a harmonised approach to data and market protection or exclusivity (known as the 8 + 2 + 1 formula). The data exclusivity period for a product begins to run on the date when the first MA for such product is granted in the EEA. It confers on the MA holder of the reference medicinal product eight years of data exclusivity and an additional two years of market exclusivity. A reference medicinal product is a medicinal product (including both small molecules and biological medicinal products), which has been authorised by an EEA country or by the Commission based on a complete dossier, i.e. with the submission of quality, pre-clinical and clinical data in accordance with Articles 8(3), 10a, 10b or 10c of Directive 2001/83/EC and to which the application for marketing authorisation for a generic/hybrid medicinal product refers, by demonstration of bioequivalence, usually through the submission of the appropriate bioavailability studies. The data exclusivity, if granted, prevents generic or biosimilar applicants from referencing the innovator’s preclinical and clinical trial data contained in the dossier of the reference product when applying for a generic or biosimilar marketing authorisation, for a period of eight years from the date on which the reference product was first authorised in the EEA. The market exclusivity period prevents a successful generic or biosimilar applicant from commercializing its product in the E.U. until 10 years have elapsed from the initial MA of the reference product in the E.U.. The ten-year market protection can be extended cumulatively to a maximum period of eleven years if during the first eight years of those ten years, the MA holder obtains an authorisation for one or more new therapeutic indications that are deemed to bring a significant clinical benefit compared to existing therapies. Even if an innovative medicinal product gains the prescribed period of data exclusivity, this exclusivity right against cross-referencing does not stop another company from seeking grant of a marketing authorisation based on data generated by its own independent research and development programme to support a full stand-alone application consisting of the data relating to preclinical tests and clinical trials.

122

Table of Contents
In the E.U., there is a special regime for biosimilars, or biological medicinal products that are similar to a reference medicinal product but that do not meet the definition of a generic medicinal product. For such products, the results of appropriate preclinical or clinical trials must be provided in support of an application for MA. Guidelines from the EMA detail the type of quantity of supplementary data to be provided for different types of biological product.
European Orphan Designation and Exclusivity. Regulation (EC) No. 141/2000 and Regulation (EC) No. 847/2000 provide that a product can be designated as an orphan drug by the European Commission if its sponsor can establish: (i) that the product is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition; (ii) either such condition affects not more than five in ten thousand persons in the European Union when the application is made, or, without incentives, it is unlikely that the marketing of the drug in the European Union would generate sufficient return to justify the necessary investment in its development; and (iii) there exists no satisfactory method of diagnosis, prevention or treatment of the condition in question that has been authorised in the European Union or, if such method exists, the product is of significant benefit compared to products available for the condition.
An Orphan Drug Designation provides a number of benefits, including fee reductions, regulatory assistance and the possibility to apply for a centralised MA. An MA for an orphan drug leads to a ten-year period of market exclusivity for the approved therapeutic indication. During this market exclusivity period, neither the EMA nor the competent authorities of the EEA countries can accept an MAA or accept an application to extend for a “similar medicinal product” and the European Commission cannot grant a marketing authorization for the same indication for a period of ten years. A “similar medicinal product” is defined as a medicinal product containing a similar active substance or substances as contained in an authorised orphan medicinal product, and which is intended for the same therapeutic indication. The period of market exclusivity is extended by two years for orphan medicinal products that have also complied with an agreed Paediatric Investigation Plan. No extension to any supplementary protection certificate can be granted on the basis of paediatric studies for orphan indications. During the period of market exclusivity, an MA may only be granted to a “similar medicinal product” if: (i) a second applicant can establish that its product, although similar to the authorised product, is safer, more effective or otherwise clinically superior; (ii) the marketing authorisation holder for the authorised product consents to a second orphan medicinal product application; or (iii) the marketing authorisation holder for the authorised product cannot supply enough orphan medicinal product. The market exclusivity period for the authorised therapeutic indication may, however, be reduced to six years if, at the end of the fifth year, it is established that the product no longer meets the criteria for Orphan Drug Designation on the basis of which it received orphan medicinal product destination, because, for example, the product is sufficiently profitable not to justify market exclusivity. Orphan drug designation must be requested before submitting an MAA. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.
Manufacturing Regulation in the E.U.. Various requirements apply to the manufacturing and placing on the E.U. market of medicinal products. The manufacturing of medicinal products in the E.U. requires a manufacturing authorization and import of medicinal products into the E.U. requires a manufacturing authorization allowing for import. The manufacturing authorization holder must comply with various requirements set out in the applicable E.U. laws, regulations and guidance, including E.U. cGMP standards. Similarly, the distribution of medicinal products within the E.U. is subject to compliance with the applicable E.U. laws, regulations and guidelines, including the requirement to hold appropriate authorizations for distribution granted by the competent authorities of EEA countries. Marketing authorization holders and/or manufacturing and import authorization, or MA holders and/or distribution authorization holders may be subject to civil, criminal or administrative sanctions, including suspension of manufacturing authorization, in case of non-compliance with the E.U. or E.U. EEA countries' requirements applicable to the manufacturing of medicinal products.

Post-authorisation Obligations in the European Union. Where an MA is granted in relation to a medicinal product in the E.U., the holder of the MA is required to comply with a range of regulatory requirements applicable to the manufacturing, marketing, promotion and sale of medicinal products. Similar to the United States, both MA holders and manufacturers of medicinal products are subject to comprehensive regulatory oversight by the EMA, the European Commission and/or the competent regulatory authorities of the individual EEA countries. The holder of an MA is subject to various obligations, such as pharmacovigilance obligations, requiring it to, among other things, report and maintain detailed records of adverse reactions, and to submit periodic safety update reports, or PSURs, to the competent authorities. All new MAAs must include a risk management plan, or RMP, describing the risk management system that the company will put in place and documenting measures to prevent or minimise the risks associated with the product. The regulatory authorities may also impose specific obligations as a condition of the marketing authorisation. Such risk-minimisation measures or post-authorisation obligations may include additional safety monitoring, more frequent submission of PSURs, or the conduct of additional clinical trials or post-authorisation safety studies. RMPs and PSURs are routinely available to third parties requesting access, subject to limited redactions. The holder must also ensure that the manufacturing and batch release of its product is in compliance with the applicable requirements. The advertising and promotion of medicinal products are subject to both E.U. and EEA countries’ laws governing promotion of medicinal products, interactions with physicians and other healthcare professionals, misleading and comparative advertising and unfair commercial practices. General requirements for advertising and promotion of medicinal products, such as direct-to-consumer advertising of prescription medicinal products are established in E.U. law. However, the details are governed by regulations in individual EEA countries and can differ from one country to another. All advertising and promotional activities for the product must be consistent with the approved SmPC, which may require approval by the competent national authorities in connection with an MA. Promotional activity that does not comply with the SmPC is considered off-label and is prohibited in the EEA. Direct-to-consumer advertising of prescription medicines is also prohibited in the European Union. The MA holder is further obligated to ensure that the advertising and promotion of its products complies with applicable European Union laws and industry code of practice as implemented in the domestic laws of ththe EEA countries. The advertising and promotional rules are enforced nationally by the EEA countires.
Paediatric Development in the European Union. In the EEA, Regulation (EC) No 1901/2006 provides that companies developing a new medicinal product must agree to a Paediatric Investigation Plan, or PIP, with the EMA’s Paediatric Committee, or PDCO, and must provide the data in compliance with the agreed PIP to accompany an MAA, unless a deferral or waiver applies, (e.g., because the relevant disease or condition occurs only in adults). The agreed PIP sets out the timing and measures proposed to generate data to support a paediatric indication of the drug for which marketing authorisation is being sought. Once the MA is obtained in all E.U. Member States and study results are included in the product information, even when negative, products are eligible for a six month extension of the protection under a Supplementary Protection Certificate, or SPC (provided an application for such extension is made at the same time as filing the SPC application for the product, or at any point up to 2 years before the SPC expires), or, in the case of orphan medicinal products, a two year extension of the orphan market exclusivity. This paediatric reward is subject to specific conditions and is not automatically available when data in compliance with the PIP are developed and submitted.

In the EEA, companion diagnostics are deemed to be in vitro diagnostic medical devices, or IVDs, and are governed by Regulation 2017/746, or IVDR, which entered into application on May 26, 2022, repealing and replacing Directive 98/79/EC. The IVDR defines a companion diagnostic as a device which is essential for the safe and effective use of a corresponding medicinal product to: (a) identify, before and/or during treatment, patients who are most likely to benefit from the corresponding medicinal product; or (b) identify, before and/or during treatment, patients likely to be at increased risk of serious adverse reactions as a result of treatment with the corresponding medicinal product.
The IVDR and its associated guidance documents and harmonized standards govern, among other things, device design and development, preclinical and clinical or performance testing, premarket conformity assessment, registration and listing, manufacturing, labeling, storage, claims, sales and distribution, export and import and post-market surveillance, vigilance, and market surveillance. IVDs, including companion diagnostics, must conform with the general safety and performance requirements, or GSPR, of the IVDR. Compliance with these requirements is a prerequisite to be able to affix the CE mark to devices, without which they cannot be marketed or sold in the EEA. To demonstrate compliance with the GSPR laid down in Annex I to the IVDR, and obtain the right to affix the CE mark, IVD manufacturers must conduct a conformity assessment procedure, which varies according to the type of IVD and its classification. Apart from low risk IVDs (Class A which are not sterile), in relation to which the manufacturer may issue an E.U. Declaration of Conformity based on a self-assessment of the conformity of its products with the GSPRs, a conformity assessment procedure requires the intervention of a Notified Body, which is an organization designated by a Competent Authority of an EEA country to conduct conformity assessments. Depending on the relevant conformity assessment procedure, the Notified Body audits and examines the technical documentation and the quality system for the manufacture, design and final inspection of the medical devices. The Notified Body issues a CE Certificate of Conformity following successful completion of a conformity assessment procedure conducted in relation to the medical device and its manufacturer and their conformity with the GSPRs. This Certificate and the related conformity assessment process entitles the manufacturer to affix the CE mark to its medical devices after having prepared and signed a related EC Declaration of Conformity.
Companion diagnostics must undergo a conformity assessment by a Notified Body. If the related medicinal product has, or is in the process of, been authorised through the centralized procedure for the authorization of medicinal products, the notified body will, before it can issue a CE Certificate of Conformity, be required to seek a scientific opinion from the EMA on the suitability of the companion diagnostic for use in relation to the medicinal product concerned. For medicinal products that have or are in the process of authorisation through any other route provided in E.U. legislation, the Notified Body must seek the opinion of the national competent authority of an E.U. Member State.
Brexit and the Regulatory Framework in the United Kingdom. The United Kingdom’s, or U.K., withdrawal from the E.U. on January 31, 2020, commonly referred to as Brexit, has changed the regulatory relationship between the U.K. and the E.U.. The Medicines and Healthcare products Regulatory Agency, or MHRA, is now the U.K.’s standalone regulator for medicinal products and medical devices. Great Britain (England, Scotland and Wales) is now a third country to the E.U.. Northern Ireland will, with regard to E.U. regulations, continue to follow the E.U. regulatory rules for now.
The U.K. regulatory framework in relation to clinical trials is governed by the Medicines for Human Use (Clinical Trials) Regulations 2004, as amended, which is derived from the CTD, as implemented into U.K. national law through secondary legislation. On January 17, 2022, the MHRA launched an eight-week consultation on reframing the U.K. legislation for clinical trials, and which aimed to streamline clinical trials approvals, enable innovation, enhance clinical trials transparency, enable greater risk
125

proportionality, and promote patient and public involvement in clinical trials. The U.K. Government published its response to the consultation on March 21, 2023 confirming that it would bring forward changes to the legislation. These resulting legislative amendments will determine how closely the U.K. regulations will align with the CTR. In October 2023, the MHRA announced a new Notification Scheme for clinical trials which enables a more streamlined and risk-proportionate approach to initial clinical trial applications for Phase 4 and low-risk Phase 3 clinical trial applications.
Marketing authorizations in the U.K. are governed by the Human Medicines Regulations (SI 2012/1916), as amended. Since January 1, 2021, an applicant for the E.U. centralized procedure marketing authorization can no longer be established in the U.K.. As a result, since this date, companies established in the U.K. cannot use the E.U. centralized procedure and instead must follow one of the U.K. national authorization procedures or one of the remaining post-Brexit international cooperation procedures to obtain a marketing authorization to market products in the U.K.. All existing E.U. marketing authorizations for centrally authorized products were automatically converted or grandfathered into U.K. marketing authorization, effective in Great Britain only, free of charge on January 1, 2021, unless the marketing authorization holder opted-out of this possibility. Northern Ireland currently remains within the scope of E.U. authorizations in relation to centrally authorized medicinal products. Accordingly, until the Windsor Framework is implemented in Northern Ireland on January 1, 2025, products falling within the scope of the E.U. centralized procedure can only be authorized through U.K. national authorization procedures in Great Britain.
The MHRA has also introduced changes to national marketing authorization procedures. This includes introduction of procedures to prioritize access to new medicines that will benefit patients, including a 150-day assessment route, a rolling review procedure and the International Recognition Procedures which entered into application on January 1, 2024. Since January 1, 2024, the MHRA may rely on the International Recognition Procedure, or IRP, when reviewing certain types of marketing authorization applications. This procedure is available for applicants for marketing authorization who have already received an authorization for the same product from a reference regulator. These include the FDA, the EMA, and national competent authorities of individual EEA countries. A positive opinion from the EMA and CHMP, or a positive end of procedure outcome from the mutual recognition or decentralized procedures are considered to be authorizations for the purposes of the IRP.
There is no pre-marketing authorization orphan designation for medicinal products in the U.K.. Instead, the MHRA reviews applications for orphan designation in parallel to the corresponding marketing authorization application. The criteria are essentially the same as those in the E.U. but have been tailored for the market. This includes the criterion that prevalence of the condition in Great Britain, rather than the E.U., must not be more than five in 10,000. Upon the grant of a marketing authorization with orphan status, the medicinal product will benefit from up to 10 years of market exclusivity from similar products in the approved orphan indication. The start of this market exclusivity period will be set from the date of first approval of the product in Great Britain.
Other Healthcare Laws and Regulations. Healthcare providers and third-party payors play a primary role in the recommendation and use of pharmaceutical products that are granted marketing approval. Arrangements with third-party payors, existing or potential customers and referral sources, including healthcare providers, are subject to broadly applicable fraud and abuse, and these laws and regulations may constrain the business or financial arrangements and relationships through which manufacturers conduct research, market, sell and distribute the products for which they obtain marketing approval. Such restrictions under applicable federal and state healthcare laws and regulations include the following:
the Federal Anti-kickback Statute, which prohibits, among other things, persons and entities from knowingly and wilfully soliciting, receiving, offering or paying remuneration, directly or indirectly, overtly or covertly, in cash or kind, in exchange for, or to induce or reward either the referral of an individual for,
126

Table of Contents
or the purchase, order or recommendation of, any good or service for which payment may be made, in whole or in part, under federal healthcare programmes such as the Medicare and Medicaid programmes. This statute has been interpreted to apply to arrangements between pharmaceutical manufacturers, on the one hand, and prescribers, purchasers, formulary managers and other individuals and entities on the other. The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively, the ACA, amended the intent requirement of the Federal Anti-kickback Statute such that a person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it to commit a violation;
the federal civil and criminal false claims, including the civil False Claims Act, or the FCA, and civil monetary penalties laws, which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid or other third-party payors that are false or fraudulent, or knowingly making, or causing to be made, a false record or statement material to a false or fraudulent claim to avoid, decrease, or conceal an obligation to pay money to the federal government. Certain marketing practices, including off-label promotion, also may implicate the FCA. In addition, the ACA codified case law that a claim including items or services resulting from a violation of the Federal Anti-kickback Statute constitutes a false or fraudulent claim for purposes of the FCA;
the federal Health Insurance Portability and Accountability Act, or HIPAA, imposes criminal and civil liability, among other things, for executing, or attempting to execute, a scheme to defraud any healthcare benefit programme or making false statements relating to healthcare matters;
the federal Physician Payments Sunshine Act, which requires certain manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Programme, with specific exceptions, to report annually to the Centers for Medicare & Medicaid Services, or CMS, information related to payments and other transfers of value made to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) other healthcare professionals (such as physician assistants and nurse practitioners) and teaching hospitals, and ownership and investment interests held by physicians and their immediate family members;
HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and their implementing regulations, which imposes certain obligations, including mandatory contractual terms, with respect to safeguarding the transmission, security and privacy of individually identifiable health information on covered entities, such as health plans, health care clearinghouses and certain healthcare providers, and their respective business associates that create, receive, maintain or transmit individually identifiable health information for or on behalf of a covered entity, and their subcontractors that use, disclose, access or otherwise process individually identifiable protected health information; and
state and non-U.S. law equivalents of each of the above federal laws, such as anti-kickback and false claims laws which may apply to items or services reimbursed by any third-party payor, including commercial insurers; state and non-U.S. laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the government that otherwise restrict payments that may be made to healthcare providers and other potential referral sources; state and non-U.S. laws that require drug manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers, drug pricing and/or marketing expenditures; state and local laws requiring the registration of pharmaceutical sales representatives; and state and non-U.S. laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and often are not pre-empted by HIPAA, and may not have the same effect, thus complicating compliance efforts.

Outside the United States, interactions between pharmaceutical companies and health care professionals are also governed by strict laws, such as national anti-bribery laws of European countries, national sunshine rules, regulations, industry self-regulation codes of conduct and physicians’ codes of professional conduct. Failure to comply with these requirements could result in reputational risk, public reprimands, administrative penalties, fines or imprisonment.
Violation of the laws described above or any other governmental laws and regulations may result in significant penalties, including administrative, civil and criminal penalties, damages, fines, the curtailment or restructuring of operations, the exclusion from participation in federal and state healthcare programmes, disgorgement, contractual damages, reputational harm, diminished profits and future earnings, imprisonment and additional reporting requirements and oversight if a person becomes subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws. Furthermore, efforts to ensure that business activities and business arrangements comply with applicable healthcare laws and regulations can be costly.
Coverage and Reimbursement. Significant uncertainty exists as to the coverage and reimbursement status of any products for which we may obtain regulatory approval. In the United States, sales of any product candidates for which regulatory approval for commercial sale is obtained will depend in part on the availability of coverage and adequate reimbursement from third-party payors. Third-party payors include government authorities and health programmes in the United States such as Medicare and Medicaid, managed care providers, private health insurers and other organisations. These third-party payors are increasingly reducing reimbursements for medical products and services. The process for determining whether a payor will provide coverage for a drug product may be separate from the process for setting the reimbursement rate that the payor will pay for the drug product. Third-party payors may limit coverage to specific drug products on an approved list, or formulary, which might not include all of the FDA-approved drugs for a particular indication. Additionally, the containment of healthcare costs has become a priority of federal and state governments, and the prices of drugs have been a focus in this effort. The U.S. government, state legislatures and foreign governments have shown significant interest in implementing cost-containment programmes, including price controls, restrictions on reimbursement and requirements for substitution of generic products for branded prescription drugs. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit our net revenue and results.
A payor’s decision to provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved. Further, coverage and reimbursement for drug products can differ significantly from payor to payor. As a result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance.
Third-party payors are increasingly challenging the price and examining the medical necessity and cost-effectiveness of medical products and services, in addition to their safety and efficacy. New metrics frequently are used as the basis for reimbursement rates, such as average sales price, average manufacturer price and actual acquisition cost. To obtain coverage and reimbursement for any product that might be approved for sale, it may be necessary to conduct expensive pharmacoeconomic studies to demonstrate the medical necessity and cost-effectiveness of the products, in addition to the costs required to obtain regulatory approvals. If third-party payors do not consider a product to be cost-effective compared to other available therapies, they may not cover the product after approval as a benefit under their plans or, if they do, the level of payment may not be sufficient to allow a company to sell its products at a profit. Additionally, any companion diagnostic test that we develop will be required to obtain coverage and reimbursement separate and apart from the coverage and reimbursement we seek for
128

Table of Contents
our product candidates, if approved. If any companion diagnostic is unable to obtain reimbursement or is inadequately reimbursed, that may limit the availability of such companion diagnostic, which would negatively impact prescriptions for our product candidates, if approved.
The marketability of any product candidates for which we receive regulatory approval for commercial sale may suffer if the government and third-party payors fail to provide adequate coverage and reimbursement. In addition, emphasis on managed care in the United States has increased and we expect will continue to increase the pressure on pharmaceutical pricing. Coverage policies and third-party reimbursement rates may change at any time. Even if favourable coverage and reimbursement status is attained for one or more products for which we or our collaborators receive regulatory approval, less favourable coverage policies and reimbursement rates may be implemented in the future.
In the European Union, pricing and reimbursement schemes vary widely from country to country. Some countries provide that products may be marketed only after a reimbursement price has been agreed. Some countries may require the completion of additional studies that compare the cost-effectiveness of a particular product candidate to currently available therapies. European Union member states may approve a specific price for a product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the product on the market. Other member states allow companies to fix their own prices for products, but monitor and control company profits.
In addition, some E.U. Member States may require the completion of additional studies that compare the cost-effectiveness of a particular medicinal product candidate to currently available therapies. This Health Technology Assessment, or HTA, process is the procedure according to which the assessment of the public health impact, therapeutic impact and the economic and societal impact of use of a given medicinal product in the national healthcare systems of the individual country is conducted. The outcome of HTA regarding specific medicinal products will often influence the pricing and reimbursement status granted to these medicinal products by the competent authorities of individual E.U. Member States. On December 15, 2021, the Health Technology Regulation, or HTA Regulation, was adopted. The HTA Regulation is intended to boost cooperation among E.U. member states in assessing health technologies, including new medicinal products, and providing the basis for cooperation at E.U. level for joint clinical assessments in these areas. When it enters into application in 2025, the HTA Regulation will be intended to harmonize the clinical benefit assessment of HTA across the European Union. In light of the fact that the United Kingdom has left the E.U., Regulation No 2021/2282 on HTA will not apply in the United Kingdom. However, the U.K. Medicines and Healthcare products Regulation Agency (“MHRA”) is working with U.K. HTA bodies and other national organizations, such as the Scottish Medicines Consortium (“SMC”), the National Institute for Health and Care Excellence (“NICE”), and the All-Wales Medicines Strategy Group, to introduce new pathways supporting innovative approaches to the safe, timely and efficient development of medicinal products.
The downward pressure on health care costs has increased over the last few years. As a result, increasingly high barriers are being erected to the entry of new products. In addition, in some countries, cross-border imports from low-priced markets exert competitive pressure that may reduce pricing within a country. Any country that has price controls or reimbursement limitations may not allow favourable reimbursement and pricing arrangements.
Health Reform. The United States and some foreign jurisdictions are considering or have enacted a number of reform proposals to change the healthcare system. There is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality or expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by federal and state legislative initiatives, including those designed to limit the pricing, coverage and reimbursement of pharmaceutical and biopharmaceutical
129

products, especially under government-funded health care programmes, and increased governmental control of drug pricing.
By way of example, in March 2010, the ACA was signed into law, and was intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add transparency requirements for the healthcare and health insurance industries, impose taxes and fees on the healthcare industry and impose additional health policy reforms. The ACA, among other things, subjects biological products to potential competition by lower-cost biosimilars, expands the types of entities eligible for the 340B drug discount programme, addresses a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Programme are calculated for drugs that are inhaled, infused, instilled, implanted or injected, increases rebates owed by manufacturers under the Medicaid Drug Rebate Programme and extends the rebate programme to individuals enrolled in Medicaid managed care organisations, establishes annual fees and taxes on manufacturers of certain branded prescription drugs and creates a new Medicare Part D coverage gap discount programme, in which manufacturers must agree to offer 50% (increased to 70% pursuant to the Bipartisan Budget Act of 2018, or BBA, effective as of January 2019) point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D.
Since its enactment, there have been executive, judicial and Congressional challenges to certain aspects of the ACA. For example, various portions of the ACA are currently undergoing legal and constitutional challenges in the United States Supreme Court. Further, on February 10, 2021, the Biden administration withdrew the federal government’s support for overturning the ACA. On June 17, 2021 the U.S. Supreme Court dismissed a challenge on procedural grounds that argued the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. Prior to the Supreme Court ruling, on January 28, 2021, President Biden issued an executive order to initiate a special enrolment period for purposes of obtaining health insurance coverage through the ACA marketplace. On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022 (“IRA”) into law, which among other things, extends enhanced subsidies for individuals purchasing health insurance coverage in ACA marketplaces through plan year 2025. The IRA also eliminates the “donut hole” under the Medicare Part D programme beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost through a newly established manufacturer discount programme. The implementation of the ACA is ongoing, and the law appears likely to continue the downward pressure on pharmaceutical pricing, especially under the Medicare programme, and may also increase our regulatory burdens and operating costs. Litigation and legislation related to the ACA are likely to continue, with unpredictable and uncertain results.
Other legislative changes have been proposed and adopted in the United States since the ACA was enacted. For example, in August 2011, the Budget Control Act of 2011 was signed into law, which, among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2012 through 2021, was unable to reach its target goals, thereby triggering the legislation’s automatic reduction to several government programmes. This includes aggregate reductions of Medicare payments to providers of up to 2% per fiscal year, which went into effect in April 2013 and, due to subsequent legislative amendments to the statute, will remain in effect through 2032 unless additional Congressional action is taken. In January 2013, the American Taxpayer Relief Act of 2012, among other things, further reduced Medicare payments to certain providers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.
There also has been heightened governmental scrutiny in the United States of pharmaceutical pricing practices in light of the rising cost of prescription drugs and biologics. Such scrutiny has resulted in several recent congressional inquiries and proposed and enacted federal and state legislation designed to,
130

Table of Contents
among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programmes, and reform government programme reimbursement methodologies for products. At the U.S. federal level, in July 2021, the Biden administration released an executive order, “Promoting Competition in the American Economy,” with multiple provisions aimed at prescription drugs. In response to Biden’s executive order, on September 9, 2021, the U.S. Department of Health and Human Services (“HHS”) released a Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug pricing reform and sets out a variety of potential legislative policies that Congress could pursue as well as potential administrative actions HHS can take to advance these principles. In addition, the IRA, among other things, (i) directs HHS to negotiate the price of certain high-expenditure, single-source drugs and biologics covered under Medicare, and subject drug manufacturers to civil monetary penalties and a potential excise tax by offering a price that is not equal to or less than the negotiated “maximum fair price” for such drugs and biologics under the law, and (ii) imposes rebates with respect to certain drugs and biologics covered under Medicare Part B or Medicare Part D to penalize price increases that outpace inflation. The IRA permits HHS to implement many of these provisions through guidance, as opposed to regulation, for the initial years. These provisions take effect progressively starting in fiscal year 2023. On August 29, 2023, HHS announced the list of the first ten drugs that will be subject to price negotiations, although the Medicare drug price negotiation program is currently subject to legal challenges. It is currently unclear how the IRA will be implemented but is likely to have a significant impact on the pharmaceutical industry. Further in response to the Biden administration’s October 2022 executive order, on February 14, 2023, HHS released a report outlining three new models for testing by the CMS Innovation Center which will be evaluated on their ability to lower the cost of drugs, promote accessibility, and improve quality of care. It is unclear whether the models will be utilized in any health reform measures in the future. Further, on December 7, 2023, the Biden administration announced an initiative to control the price of prescription drugs through the use of march-in rights under the Bayh-Dole Act. On December 8, 2023, the National Institute of Standards and Technology published for comment a Draft Interagency Guidance Framework for Considering the Exercise of March-In Rights which for the first time includes the price of a product as one factor an agency can use when deciding to exercise march-in rights. While march-in rights have not previously been exercised, it is uncertain if that will continue under the new framework.
At the state level, individual states in the United States have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. For example, on January 5, 2024, the FDA approved Florida’s Section 804 Importation Program (SIP) proposal to import certain drugs from Canada for specific state healthcare programs. It is unclear how this program will be implemented, including which drugs will be chosen, and whether it will be subject to legal challenges in the United States or Canada. Other states have also submitted SIP proposals that are pending review by the FDA. Any such approved importation plans, when implemented, may result in lower drug prices for products covered by those programs.
We expect that these initiatives, as well as other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and lower reimbursement, and in additional downward pressure on the price that we receive for any approved product. Further, any reduction in reimbursement from Medicare or other government-funded programmes may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialise our product candidates.
Further, additional healthcare reform initiatives may arise from future legislation or administrative action.

Data Privacy and Security Laws. We also are or may become subject to privacy laws in the jurisdictions in which we are established, have partners or sell or market our products or run clinical trials. For example, we are or may become subject to privacy and data protection laws, such as the E.U. GDPR and/or U.K. GDPR and HIPAA in the United States, among many others. Our regulatory obligations in foreign jurisdictions could harm the use or cost of our solution in international locations as data protection and privacy laws and regulations around the world continue to evolve.
Certain aspects of our business, including those for which we rely upon collaborators, service providers, contractors or others, are or may become subject to HIPAA and its implementing regulations, which establish standards for covered entities (healthcare providers, health plans and healthcare clearinghouses) governing the conduct of certain electronic healthcare transactions and protecting the security and privacy of protected health information, including, among other requirements, mandatory contractual terms and technical safeguards designed to protect the privacy, security and transmission of protected health information and notification to affected individuals and regulatory authorities in the event of certain breaches of security of protected health information. The American Recovery and Reinvestment Act of 2009, commonly referred to as the economic stimulus package, included sweeping expansion of HIPAA’s privacy and security standards called for by HITECH, which became effective on February 17, 2010. Among other things, HITECH makes HIPAA’s privacy and security standards directly applicable to business associates, or independent contractors or agents of covered entities, that receive or obtain protected health information in connection with providing a service on behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates and their covered subcontractors, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney’s fees and costs associated with pursuing federal civil actions.
Even when HIPAA does not apply, failing to take appropriate steps to keep consumers’ personal information secure can constitute unfair acts or practices in or affecting commerce and be construed as a violation of Section 5(a) of the Federal Trade Commission Act, or the FTCA, 15 U.S.C § 45(a). The Federal Trade Commission expects a company’s data security measures to be reasonable and appropriate in light of the sensitivity and volume of consumer information it holds, the size and complexity of its business, and the cost of available tools to improve security and reduce vulnerabilities.
In Europe, the E.U. GDPR and the U.K. GDPR impose strict requirements in relation to processing the personal data of individuals located, respectively, within the EEA and/or U.K. and/or to processing that occurs in the context of an establishment in, respectively, the EEA and/or U.K. For example, under the E.U. GDPR and the U.K. GDPR, government regulators may impose temporary or definitive bans on data processing, as well as fines of up to: 20 million euros under the E.U. GDPR or 17.5 million pounds sterling under the U.K. GDPR; or 4% of annual global revenue, whichever is greater. Further, individuals may initiate litigation related to our processing of their personal data. Other countries outside of Europe have enacted or are considering enacting similar comprehensive data privacy and security laws and regulations, which could increase the cost and complexity of delivering our services and operating our business.
In particular, many jurisdictions have enacted data localisation laws and cross-border personal data transfer laws. These laws may make it more difficult for us to transfer personal data across jurisdictions, which could impede our business. If we cannot implement a valid compliance mechanism for cross-border data transfers, we may face increased exposure to regulatory actions, substantial fines, and injunctions against processing or transferring personal data from the E.U., U.K. or elsewhere. Furthermore, the inability to transfer personal data to the United States or other jurisdictions outside the EEA and U.K. could significantly and negatively impact our business operations, including by limiting our ability to collaborate with parties that are subject to European and other data privacy and security

laws or requiring us to increase our personal data processing capabilities in Europe and/or elsewhere at significant expense.
In the United States, state laws may be more stringent, broader in scope or offer greater individual rights with respect to health information than HIPAA, and state laws may differ from each other, which may complicate compliance efforts. By way of example, California recently enacted the California Consumer Privacy Act, or CCPA, which creates new individual privacy rights for California residents and places increased privacy and security obligations on entities handling certain personal data of such residents. The CCPA requires covered companies to provide new disclosures to California residents about such companies’ data collection, use and sharing practices and provide such residents new ways to opt out of certain disclosures of personal information and provides such residents with additional causes of action. The CCPA became effective on January 1, 2020, and (a) allows enforcement by the California Attorney General, with fines set at $2,500 per non-intentional violation or $7,500 per intentional violation and (b) authorises private lawsuits to recover statutory damages for certain data breaches. Additionally, a new privacy law, the California Privacy Rights Act, or CPRA, was recently approved by California voters in November 2020. The CPRA significantly modifies the CCPA, resulting in further uncertainty and requiring us to incur additional costs and expenses to comply.
Our obligations related to data privacy and security are quickly changing in an increasingly stringent fashion. These obligations may be subject to differing applications and interpretations, which may be inconsistent or in conflict among jurisdictions. Preparing for and complying with these obligations requires us to devote significant resources (including, without limitation, financial and time-related resources). These obligations may necessitate changes to our information technologies, systems, and practices and to those of any third parties that process personal data on our behalf. In addition, these obligations may require us to change our business model. Although we endeavor to comply with all applicable data privacy and security obligations, we may at times fail (or be perceived to have failed) to do so. Moreover, despite our efforts, our personnel or third parties upon whom we rely may fail to comply with such obligations which could impact our compliance posture. If we fail, or are perceived to have failed, to address or comply with data privacy and security obligations, we could face significant consequences. These consequences may include, but are not limited to, government enforcement actions (e.g., investigations, fines, penalties, audits, inspections, and similar), litigation (including class-related claims), additional reporting requirements and/or oversight, bans on processing personal data; orders to destroy or not use personal data; and imprisonment of company officials. Any of these events could have a material adverse effect on our reputation, business, or financial condition, including but not limited to: loss of customers, interruptions or stoppages in our business operations, inability to process personal data or to operate in certain jurisdictions, limited ability to develop or commercialize our products, expenditure of time and resources to defend any claim or inquiry, adverse publicity, or revision or restructuring of our operations.
For more information, please see “Risk Factors — Compliance with stringent and evolving global privacy and data security requirements could result in additional costs and liabilities to us or inhibit our ability to collect and process data globally, and the failure to comply with such requirements could subject us to significant fines and penalties, which may have a material adverse effect on our business, financial condition or results of operations.”

Additional Regulation. In addition to the foregoing, provincial, state and federal U.S. and European Union laws regarding environmental protection and hazardous substances affect our business. These and other laws govern our use, handling and disposal of various biological, chemical and radioactive substances used in, and wastes generated by, our operations. If our operations result in contamination of the environment or expose individuals to hazardous substances, we could be liable for damages and governmental fines.
We believe that we are in material compliance with applicable environmental laws and that continued compliance therewith will not have a material adverse effect on our business. We cannot predict, however, how changes in these laws may affect our future operations.
Anti-corruption Laws. We are subject to the U.S. Foreign Corrupt Practices Act of 1977, as amended, or the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the U.S.A. PATRIOT Act, the U.K. Bribery Act 2010 and the U.K. Proceeds of Crime Act 2002 and possibly other state and national anti-bribery and anti-money laundering laws in countries in which we conduct activities, collectively, Anti-Corruption Laws. Among other matters, such Anti-Corruption Laws prohibit corporations and individuals from directly or indirectly paying, offering to pay or authorizing the payment of money or anything of value to any foreign government official, government staff member, political party or political candidate or certain other persons, to obtain, retain or direct business, regulatory approvals or some other advantage in an improper manner. We can also be held liable for the acts of our third-party agents under the FCPA, the U.K. Bribery Act 2010 and possibly other Anti-Corruption Laws. In the healthcare sector, anti-corruption risk can also arise in the context of improper interactions with doctors, key opinion leaders and other healthcare professionals who work for state-affiliated hospitals, research institutions or other organisations.
Government Regulation Outside of the United States, the European Union and the United Kingdom.
In addition to regulations in the United States, the European Union and the United Kingdom, we may be subject to a variety of regulations in other jurisdictions governing, among other things, clinical studies and any commercial sales and distribution of their products. Whether or not we obtain FDA, MHRA, or EMA approval for a product, we must obtain the requisite approvals from regulatory authorities in foreign countries prior to the commencement of clinical studies or marketing of the product in those countries. Certain countries outside of the United States, the United Kingdom and the European Union have a similar process that requires the submission of a clinical study application much like the IND, or CTA, prior to the commencement of human clinical studies. The requirements and process governing the conduct of clinical studies, product licensing, coverage, pricing and reimbursement vary from country to country. In all cases, the clinical studies are conducted in accordance with GCP and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.
Legal Proceedings. From time to time, we may become involved in legal proceedings arising in the ordinary course of our business. We are not currently subject to any material legal proceedings.

Overview
We are a drug design company using artificial intelligence, or AI, and other technologies to efficiently design and develop differentiated medicines for diseases with high unmet patient need. The focus of our platform is to improve the probability of successful drug development by identifying and resolving likely points of failure using our AI design technology, translational systems and clinical modelling. We have demonstrated our platform can achieve design goals beyond current industry standards by advancing multiple development candidates with differentiated properties, four of which are currently in clinical trials. Our internal pipeline is primarily focused on oncology, but we also use our design capabilities with partners to expand our pipeline and generate income.
We believe many drug candidates fail due to predictable drug design issues. For more than a decade, we have been utilising AI to overcome these design issues and create better quality medicines. We also integrate novel experimental and automation systems in order to test and validate our AI-based simulations. Our closed loop of virtual design and physical experimentation is a critical advantage in learning quickly, generating data that would not be available externally, cost effectiveness and reproducibility.
Our technology platform spans generative AI, active learning, machine learning, physics-based systems, large language models and many other predictive systems. However, the output of our technology is always a measurable drug. We have over 20 drug programmes advancing, including at least two with expected clinical milestones in 2024. Each drug we create needs to have a meaningful design advantage over known competitors that is expected to have clinical benefit and can be clearly measured.

Our lead internal candidate, a CDK7 inhibitor known as GTAEXS617 (‘617), is currently in a Phase 1/2 trial with initial data expected in the second half of this year. ‘617 was precision designed to manage the potential toxicities associated with CDK7 as well as optimising pharmacokinetics for maximising on-target efficacy.
We designed a PKC-theta inhibitor for Bristol Myers Squibb that they then in-licensed and are currently testing in Phase 1 clinical trials. Despite PKC-theta being a target of high interest with more than a dozen companies having attempted to design compounds for the target, no competitors had been potent and selective and our candidate has the potential to be first-in-class. We have ongoing milestones and royalties associated with the programme.
We have two additional internal programmes in IND-enabling studies targeting LSD1 and MALT1. Both of these candidates were designed to mitigate known toxicities that have been seen in competitive programmes. By understanding the origin of these toxicities and designing against them we believe we have produced two candidates that will have an improved probability of success in clinical development.
Over time, we believe our transformational way of designing and developing drugs can change the industry's underlying pharmacoeconomic model, what we call 'shifting the curve'. We aim to demonstrate that it is simultaneously possible to improve probability of success through designing better quality drugs while also reducing investment requirements through improved technologies and process.

Recent Developments
On February 2, 2023, we announced that EXS4318 (‘4318) a compound precision designed by us and in-licensed by Bristol Myers Squibb, or BMY, in August 2021, had entered Phase 1 clinical trials in the United States. The compound is in development for immunology & inflammation (I&I) indications. BMY will oversee the clinical and commercial development and we are eligible for milestone payments and, if approved, tiered royalties on net product sales.
On March 14, 2023, we announced two new wholly owned precision oncology development candidates, EXS74539 (‘539), an LSD1 inhibitor and EXS73565 (‘565), a MALT1 protease inhibitor. We expect to submit an IND for ‘539 by mid-2024, and ‘565 is continuing to progress through INDA/CTA enabling studies. Both molecules were funded through a 2019 collaboration with Celgene, which was acquired by BMY, and each molecule met the criteria for a molecule for which BMY could exercise its option. BMY's options to the candidates have lapsed and we maintain all worldwide rights to both compounds.
On July 10, 2023, we announced that the first patient was enrolled in the Phase 1/2 ELUCIDATE clinical trial of GTAEXS617 (‘617), a precision designed potent and selective CDK7 inhibitor. The trial is enrolling patients across six advanced solid tumour types: head and neck cancer, colorectal cancer, pancreatic cancer, non-small cell lung cancer, or NSCLC, HR+/HER2- breast carcinoma and ovarian cancer.
On July 18, 2023, we announced the initiation of EXCYTE-1, the first multi-centre trial evaluating the potential of our functional precision medicine in solid tumours, with a focus on ovarian cancer. EXCYTE-1 is a prospective observational study in ovarian cancer to investigate the relationship between ex vivo drug response in primary tumour-derived samples using our precision medicine platform and actual patient clinical responses.

On September 19, 2023, our wholly owned subsidiary, Exscientia AI Ltd, and the Healthcare Business of Merck KGaA, Darmstadt, Germany entered into a collaboration agreement focused on the discovery of novel small molecule drug candidates across oncology, neuroinflammation and immunology using Exscientia’s AI-driven precision drug design and discovery capabilities. Three potential first-in-class or best-in-class targets have been identified as the initial focus of the partnership.
On September 27, 2023, we received confirmation of the achievement of a research milestone in our collaboration with Sanofi for its first immunology and inflammation target, in relation to which we received a cash payment of $4,000,000.
On October 3, 2023, we announced an update to our pipeline prioritisation strategy that is designed to further strengthen our focus, investment and infrastructure on the programmes that we believe have the greatest potential for differentiation and value creation. This included prioritising the advancement of our CDK7 inhibitor (‘617) and LSD1 inhibitor (‘539) and discontinuing internal development of EXS21546 (‘546), including closing down the Phase 1/2 IGNITE clinical trial of ‘546 for the treatment of relapsed/refractory renal cell carcinoma and NSCLC.
On October 9, 2023, we ended our collaboration with EQRx following the announcement of the acquisition of EQRx by Revolution Medicines Inc. In connection with the termination, we agreed to return the unspent funds advanced to us by EQRx at the initiation of the collaboration and we obtained full and exclusive rights to all intellectual property on the three initial targets that was created during the collaboration. Accordingly, $8,750,000 was transferred to EQRx on October 12, 2023 in complete satisfaction of our financial obligations under the collaboration agreement.
In October 2023, we mutually determined to prioritise certain projects and not to proceed with the development of others within the Group’s collaboration with BMY.
On December 5, 2023, we announced that we received a $2,300,000 grant from Open Philanthropy, a philanthropic funder with several programmes in global health and wellbeing. Under this grant, Exscientia aims to harness the activation of the host interferon response as a therapeutic approach for pandemic influenza.
On December 21, 2023, we announced an amendment of our current collaboration with Sanofi to add a new discovery stage programme identified and initially advanced by Exscientia. The programme aims to design a potential best in class molecule by combining Exscientia’s research platform with Sanofi's leading development expertise. Exscientia is eligible for additional upfront and research stage milestones on top of the existing agreement.
On February 7, 2024, we announced the initiation of EXCYTE-2, an observational clinical study in acute myeloid leukaemia, or AML, to investigate the relationship between ex vivo drug response, measured in primary blood or bone marrow samples and actual patient clinical response. The EXCYTE-2 study will collect blood and bone marrow samples from first-line patients with AML, with an option to expand to second-line patients. In addition, the study allows for the evaluation of activity of ‘539, our LSD1 inhibitor, in a large clinically annotated sample set.
On February 13, 2024, our board of directors terminated the employment of Andrew Hopkins as our Chief Executive Officer and Principal Executive Officer, and appointed David Hallett, our Chief Scientific Officer, as Interim Chief Executive Officer and Interim Principal Executive Officer. Dr. Hopkins was also removed from his role as a member of the board of directors, and Dr. Hallett was appointed to serve as a member of the board of directors on an interim basis. Dr. Hopkins’ conduct did not impact our consolidated financial statements or our internal controls over financial reporting, and his termination is unrelated to our operational or financial performance.

A. Operating Results
Components of Results of Operations
Revenue. We generate revenue broadly from two streams that relate to our principal activities:
Licensing fees: We receive licensing fees from partnered programmes where we develop intellectual property on behalf of a collaboration partner. These agreements either assign all of the designated intellectual property to the partner from inception or grant an exclusive option to the partner to acquire rights to the future development and commercialisation of the intellectual property. As part of these agreements, we may receive future milestone and royalty payments upon achievement of clinical, regulatory and commercial milestones; and
Service fees: We generate service fees from drug discovery collaboration agreements where we are utilising our proprietary technology to develop novel intellectual property on behalf of the collaboration partner, but do not have any rights to future milestones and royalties as a direct result of the agreement. Until March 2023, we also generated service revenues through our Exscientia GmbH entity related to collaboration agreements that existed with Exscientia GmbH at the time of our acquisition.
We receive four types of payments within the two revenue streams:
Upfront payments, which are generally payable upon execution of the collaboration agreement or on initiation of a project;
Research funding (including term extension payments), which is generally payable throughout the collaboration at defined intervals that are set out in the agreement (e.g., quarterly or at the beginning of a specific phase of work) and is intended to fund research (internal and external) to develop the drug compound that is the subject of the collaboration;
Milestone payments, which are linked to the achievement of events that are defined in the agreement, such as clinical and regulatory milestones; and
Opt-in payments, which are similar in principle to milestone payments, but are payable when the partner exercises its option to take ownership of the designated intellectual property. These payments only exist where we initially retained ownership of the designated intellectual property.
In addition to the payments described above, we may also receive milestone payments upon the first commercial sale of a product, if and when approved, the amount of which is based on the territory the sale occurs in, and royalties based on worldwide net sales. These amounts have not been included within the transaction price for any contract as of December 31, 2023 and 2022. We have only recognised revenue in respect of non-cancellable, non- refundable payments and achieved milestones due under executed collaboration contracts. Any payments which relate to future milestones or options under the control of our collaboration partners have not been recognised.
Costs of Sales. Costs of sales relates to costs from third-party CRO’s, as well as internal labour and absorbed overhead incurred in relation to collaboration arrangements and drug discovery agreements for third parties which have been designated as contracts with customers in accordance with IFRS 15. External CRO costs are the main driver for our costs of sales, representing 66% and 77% of total costs of sales during the periods ending December 31, 2023 and 2022 respectively. The reduction is primarily a result of increased activity in relation to the Company’s collaboration with Sanofi, where a higher proportion of internal costs are incurred, in addition to the transition of projects to strategic CRO partners in lower cost jurisdictions.
We expect our cost of sales to increase in the future as we commence additional collaboration projects.

140

Gross (loss)/profit. Gross (loss)/profit represents revenue less costs of sales. Gross margin is gross profit/(loss) expressed as a percentage of revenue. Our gross margin may fluctuate from period to period as a result of our drug discovery collaboration activities. For example, the revenue associated with collaboration up-front payments is recognised over time and is adjusted due to changes in the estimated costs to be incurred in satisfying the related performance obligation, while certain opt-in and milestone payments are recognised when assessed to be highly probable, which is generally upon achievement.
For obligations in which revenue is recognised at a point in time, that point in time is the date at which the satisfaction of the performance obligation is mutually agreed with our customer. For obligations discharged over time the Group recognises revenue equal to recoverable costs incurred for new collaborations from their inception until such time as the collaboration is sufficiently progressed such that the Group can reliably estimate the level of profit that will be achieved from delivery of the related performance obligations. Revenue from potential milestones or royalties are typically not recognised at the initiation of a contract. Upfront payments that include performance obligations are recognised as those obligations are satisfied. As a result of this, until total costs and time to completion can be reliably estimated, a gross profit/(loss) may be recognised on individual customer contracts despite the expectation that the relevant contract will be profitable overall.
Therefore, we believe that gross (loss)/profit is not currently a helpful predictor of the future performance of our business.
Research and Development Expenses. Research and development expenses consist of costs associated with our majority-owned and co-owned drug discovery programmes and costs incurred for the ongoing development of our technology platform. All research and development costs are expensed as incurred due to scientific and technological uncertainty. Research and development expenses primarily consist of:
internal personnel-related expenses, including salaries, benefits, bonuses and stock-based compensation for employees engaged in research and development functions;
external expenses incurred under agreements with CROs and other consultants involved in our research and development;
facilities, depreciation and amortisation, insurance and other direct and allocated expenses incurred as a result of research and development activities; and
costs associated with operating our digital infrastructure, including allocated software, computing capacity costs, and laboratory-related costs, including laboratory equipment depreciation.

All direct external research and development expenditures are tracked on a programme-by-programme basis and consist primarily of fees paid to CROs relating to wholly and jointly operated discovery programmes in the later stages of drug discovery, including lead optimisation, preclinical and clinical studies, and are assigned to the individual programmes. We utilise internal employee time tracking data to allocate internal research and development expenses, such as employee costs, laboratory supplies, facilities, depreciation, or other indirect costs, to specific programmes because these costs are deployed across multiple programmes.
We expect our research and development expenses to increase for the foreseeable future as we continue to expand and advance our wholly and jointly operated drug pipeline in addition to investing in our technology platform. Drug development generally becomes more costly as programmes advance into later stages, as these trials typically require a higher number of patients enrolled and sites operated. We cannot determine with certainty the timing of initiation, the duration, or the completion costs of current or future clinical trials of our drug candidates due to the inherently unpredictable nature of drug development. At this time, we cannot reasonably estimate or know the nature or timing of the efforts that will be necessary to complete the development and commercialisation of any drug candidates that we develop from our
141

programmes. As a result, our research and development expenses may vary substantially from period to period based on the timing of our research and development activities. All of our programmes are at an early stage of development, and we may experience numerous unforeseen events during, or as a result of, the clinical trial process that could delay or prevent commercialisation of our drug candidates and result in a significant change in the costs and timing associated with the development of programmes.
General and Administrative Expenses. General and administrative expenses consist of personnel-related expenses associated with our executive, legal, finance, human resources, information technology and other administrative functions, including salaries, benefits, bonuses and stock-based compensation. General and administrative expenses also include professional fees (including fees relating to external legal, accounting and consulting services), allocated overhead costs, including depreciation charges associated with our information technology, facilities and other administrative functions.
We expect that our general and administrative expenses will remain relatively flat in the near to mid-term.
Share-based Compensation. Share-based compensation expenses are recorded within either research and development expenses or administrative expenses depending on the activities of the employees to which they relate.
Our share-based compensation relates to share awards granted to employees, non-employees and directors in connection with Exscientia’s share-based compensation plans. Share-based payment awards primarily consist of service based awards, some of which also have market-based performance conditions. We measure the fair value of service based awards at the grant date using the Black-Scholes option pricing model, while the fair value of those awards also containing market-based performance conditions is determined at the grant date using a Monte Carlo simulation model. These models incorporate various assumptions including the expected volatility of our ordinary shares, the expected term of the awards and a risk-free interest rate. We amortise the fair value over the vesting term on a straight-line basis. At each statement of financial position date, the Group revises its estimate of the number of awards that are expected to become exercisable based on forfeiture rates, and with the exception of changes in the estimated probability of achieving market-based performance conditions, adjustments are made such that at the end of the vesting period the cumulative charge is based on the number of awards that eventually vest. If any of the assumptions used in the models change significantly for future grant valuations, share-based compensation expense may differ materially in the future from that recorded in the current period.
We expect that our share-based compensation expenses will decrease somewhat as a result of equity award forfeitures relating to our former chief executive officer.
Other Income. Other income consists of income from grants, tax credits receivable from the United Kingdom’s Research and Development Expenditure Credit Scheme, or RDEC, and Austrian R&D tax credits.
As of January 1, 2023, we had four grants: consisting of a European governmental grant, a grant from the Gates Foundation, a grant from the Austrian Research Promotion Agency (“FFG”) and a grant from the Austrian Wirtshaftsservice, with the European governmental grant having ended in April 2023. The grant with the Gates Foundation provides reimbursement for certain personnel, consumables and overhead costs incurred in the performance of research and development activities, while the FFG grant relates to the early stage testing of a drug’s action in solid tumour patient samples with high content microscopy and deep-learning. The Austrian Wirtshaftsservice grant provides funding in respect of capital investments made in the period from August 2020 to the end of February 2022.

142

On November 15, 2023 the Group entered into a grant from Open Philanthropy Project LLC, in relation to which the Group received £1,895,000 ($2,300,000) in order to fund further exploration of the requirements for the activation of key aspects of the interferon response of known antiviral effects against influenza and COVID-19. The grant provides reimbursement for certain personnel, consumables and overhead costs incurred in the performance of the related research and development activities.
As of December 31, 2023 all amounts related to the above grants had been received (December 31, 2022: £561,000 outstanding).
The other component of other income relates to certain R&D tax credits received by the Group as follows:
RDEC relates to U.K. tax credits receivable in relation to eligible research and development expenditures that are not eligible to be included in the Small and Medium-sized Enterprises research and development tax relief programme, or SME Programme, as discussed below under the section entitled Income Tax Benefit, such as when we receive income from a collaboration partner or grant funding for certain projects. These costs are claimed under the RDEC scheme, which up until April 1, 2023 offered a tax credit of up to 13% for qualifying expenditures (subsequently 20%), with certain subcontracted expenditures receiving an 8.5% tax credit (subsequent to April 1, 2023 13%). Under the RDEC regime, qualifying subcontracted costs are limited to those undertaken with certain institutions such as charities, higher education institutes, or scientific research organisations.
Under the RDEC regime, the tax credit is accounted for in our profit before tax under other income, with an associated tax charge recognised at the prevailing rate of corporation tax in the United Kingdom before total loss for the year. Amendments to the U.K. research and development tax credit regime have been proposed that may (unless limited exceptions apply) introduce restrictions on the tax relief that can be claimed for expenditure incurred on sub-contracted activities or externally provided workers, where such sub-contracted activities are not carried out in the U.K. or such workers are not subject to U.K. payroll taxes. These amendments are expected to take effect for accounting periods commencing on or after April 1, 2024. In addition, the U.K. government has proposed merging the SME Programme and the RDEC regime into a single scheme with effect from April 2024; if such proposal is enacted in the manner provided in recently-published draft legislation, and we do not qualify as an “R&D-intensive SME”, we will either cease to be able to claim cash rebates in respect of our research and development activities or only be able to receive such cash rebates at a significantly lower rate than at present. These and other potential future changes to the U.K. research and development tax relief programs may mean we no longer qualify or have a material impact on the extent to which we can make claims or benefit from them.
We also receive an Austrian Research Premium in relation to eligible research and experimental development expenditures. The research premium is accounted for within other income at a rate of 14%.
Foreign Exchange (Losses)/Gains. Foreign exchange (losses)/gains arises primarily on the translation of our non-pounds sterling denominated cash and cash equivalents, in addition to outstanding monetary non-pounds sterling financial assets and liabilities, including trade receivables.
Gains/(Losses) on Forward Contracts. The Group enters into contracts whereby fixed amounts of currencies are exchanged at a pre-determined rate at a future date. These currency forward contracts are initially recognised at fair value on the date at which the derivative contract is executed, and are subsequently re-measured at fair value each period-end. Any gains and losses arising from changes in the fair value of derivatives are recognised within profit or loss.
Finance Income. Finance income arises primarily from interest income on cash, cash equivalents and short-term bank deposits.
143

Finance Expenses. Finance expenses consist of interest expenses related to lease liabilities as recognised under the accounting standard IFRS 16 ‘Leases’, interest in relation to unwinding the discounting of restoration provisions recognised in relation to the Group’s leased premises and loan and bank interest payable.
Share of Loss of Joint Venture. Share of loss of joint ventures consist of our share of costs incurred by RE Ventures I, LLC, the joint venture entity we own equally with Rallybio and RE Ventures II, LLC; however, no expenses were incurred during the year.
Should we establish additional joint collaborations that meet the Joint Venture definition under IFRS 11, our share of the profits or losses of those arrangements will impact this in future.
Income Tax Benefit. Our income tax benefit is comprised of research and development tax credits recoverable in the United Kingdom offset by income tax payable in the United States, Austria and Japan. We are subject to corporation taxation in the United Kingdom. Exscientia AI Limited’s wholly owned U.S. subsidiaries, Exscientia, Inc., Exscientia Ventures I, Inc. and Exscientia Ventures II, Inc. are subject to corporation taxation in the United States. Exscientia AI Limited’s wholly owned subsidiary Exscientia KK is subject to corporation taxation in Japan. Exscientia AI Limited’s wholly owned subsidiary Exscientia GmbH is subject to corporation tax in Austria. Due to the nature of our business, we have generated losses since inception. Exscientia, Inc., Exscientia GmbH and Exscientia KK all generate taxable profits due to intercompany transfer pricing arrangements.
As a group that carries out extensive research and development activities, we benefit from the U.K.’s small-and-medium enterprises research and development tax credit regime, or SME Programme, and are able to surrender some of our losses for a cash rebate of up to 33.35% of expenditures related to eligible research and development projects up to April 1, 2023. Qualifying expenditures largely consist of employment costs for relevant staff, external workers provided by CROs, and software and consumables used in research and development projects. Certain subcontracted qualifying research and development expenditures are eligible for a cash rebate of up to 21.68% up to April 1, 2023. A large portion of costs relating to our research and development is eligible for inclusion within the tax credit cash rebate claims. The SME Programme credit is recognised in full in the income tax benefit.
The SME Programme cash rebate rate has reduced to 18.6% for qualifying research and development expenditure incurred on or after April 1, 2023. Amendments to the U.K. R&D tax credit regime that are contained in the recently enacted Finance Bill will increase the cash rebate that may be claimed from such date to 26.97% of qualifying expenditure, if we qualify as an “R&D-intensive SME” for an accounting period (broadly, a loss making SME whose qualifying R&D expenditure represents 40% (or, from April 1, 2024, 30%) or more of its total expenditure for that accounting period. If it is determined that we qualified as an R&D-intensive SME for the accounting period ended December 31, 2023 (and as such that the cash tax rebate for the period April 1, 2023 to December 31, 2023 can be claimed at 26.97% of eligible expenditure rather than the 18.6% rate currently utilised), the expected impact would be to increase the income tax benefit for the year to December 31, 2023 by £3,961,000.
Additionally, amendments will come into effect from April 1, 2024 that (i) (unless limited exceptions apply) introduce restrictions on the tax relief that can be claimed for expenditure incurred on sub-contracted R&D activities or externally provided workers, where such sub-contracted activities are not carried out in the U.K. or such workers are not subject to U.K. payroll taxes, and (ii) merge the SME Program and the RDEC Program into a single scheme. If we do not qualify as an R&D-intensive SME, we will either cease to be able to claim cash rebates in respect of our R&D activities, or only be able to receive such cash rebates at a significantly lower rate than at present. These and other potential future changes to the U.K. R&D tax relief programmes may mean we no longer qualify for them or have a material impact on the extent to which we can make claims or benefit from them.

Service fees during the year December 31, 2023 and 2022 relates to revenues generated from legacy contracts held by Exscientia GmbH, in relation to which revenue is recognised at a point in time.
On January 4, 2022 we entered into a strategic research collaboration with Sanofi to develop an AI-driven pipeline of precision engineered medicines. Research under the collaboration is focused on up to 15 novel small molecule candidates across oncology and immunology, in relation to which we received an up-front cash payment of £74,242,000 ($100,000,000) with the potential of $5,200,000,000 in total milestones plus tiered royalties over the duration of the collaboration.
On March 11, 2022, BMY extended its first collaboration arrangement with us by six months in order to generate additional data, in relation to which we received a cash payment of $5,000,000. The term
145

extension payment was treated as an addition to the transaction price relating to the collaboration’s partially unsatisfied performance obligations relating to the design and development of candidates for collaboration targets, with a cumulative recognition of revenue at that date based upon the progress towards satisfaction of the related performance obligations in accordance with paragraph 21b of IFRS 15. The remaining element of the transaction price was recognised as revenue over the remainder of 2022 as the performance obligations were satisfied.
On May 30, 2022, we ended our pre-existing collaboration arrangement with Bayer AG by mutual agreement. Upon ending the agreement all remaining performance obligations pertaining to the contract were deemed to be fully discharged, resulting in the recognition of revenues totalling £1,153,000 at that point.
On July 27, 2023, we and Sanofi S.A. entered into an amendment to the collaboration agreement executed between the parties on January 4, 2022, pursuant to which certain terms, including with respect to certain target substitution and milestone payments, relating to targets under the collaboration were amended. There was no change to the overall contract transaction price as a result of the amendment, and no significant adjustment to revenue recognised on partially satisfied performance obligations as at the amendment date.
On September 19, 2023 we entered into a collaboration agreement with the Healthcare Business of Merck KGaA, Darmstadt, Germany, or “Merck KGaA, Darmstadt, Germany”, focused on the discovery of novel small molecule drug candidates across oncology, neuroinflammation and immunology using Exscientia’s AI-driven precision drug design and discovery capabilities. Three potential first-in-class or best-in-class targets have been identified as the initial focus of the partnership, in relation to which we received an up-front cash payment of $20,100,000 (net of withholding taxes of $3,181,000 which are expected to be received in the second half of 2024), with the potential of up to $674,000,000 total in discovery, development, regulatory and sales-based milestones in addition to royalty payments on net sales.
On September 27, 2023 we received confirmation of the achievement of a research milestone in our collaboration with Sanofi for our first inflammation and immunology target, in relation to which we received a cash payment of $4,000,000. Until achievement, this milestone was treated as constrained variable consideration relating to the drug design work undertaken in relation to the associated project, and as such it has been added to the transaction price for the related partially satisfied performance obligation from from the point of achievement, with revenue recognised as the performance obligation is satisfied.
On December 21, 2023, we amended our current collaboration with Sanofi to incorporate an additional discovery stage programme, in relation to which a cash payment of $4,000,000 was received in February 2024, with revenue recognised over time as the related performance obligation is satisfied. Under the terms of the amended agreement, we are eligible to receive up to $45,000,000 in upfront and preclinical milestone payments, as well as development, regulatory and sales-based milestone payments of over $300,000,000 and tiered royalties on product sales if this compound achieves all milestones under the collaboration agreement.
Included within revenues during the year ended December 31, 2023 are amounts totalling £6,859,000 relating to non-refundable upfront payments on projects under our ongoing collaboration with BMY. These amounts have been recognised as revenue during the year as we and BMY mutually determined not to proceed with further development of these projects and to prioritise others within the collaboration.
We have assessed our significant collaboration arrangements with commercial partners and determined that no provision for future operating losses is required as at December 31, 2023, after taking into account
146

expected future cash inflows and remaining contract liability amounts for each collaboration relative to the remaining unavoidable costs of meeting the respective contracts’ obligations in each instance.

Costs of Sales
The following table presents our costs of sales for the periods indicated (in thousands):
Year ended December 31,

Research and development expenses for the year ended December 31, 2023 were £128.4 million, as compared to £128.9 million for the same period ended December 31, 2022, with decreases in costs resulting from pipeline prioritisation activities and cost savings from operational efficiencies, including achieving faster cycle times and lower outsourcing costs, being largely offset by additional costs incurred in relation to clinical and late stage pre-clinical programs as a result of pipeline progression over the
147

period, and additional depreciation and amortisation expenses of £4.1 million resulting from the Group’s continuing investment in plant and equipment, including in relation to our automation laboratory in Milton Park, Oxfordshire which opened in the second quarter of 2023.
An impairment charge of £1.3 million was recognised during the year ended December 31, 2023 relating to certain plant and equipment acquired in relation to our Biologics programme, which was de-prioritised in the fourth quarter of 2023.
General and Administrative Expenses. General and administrative expenses for the year ended December 31, 2023 were £45.3 million, as compared to £38.4 million for the same period ended December 31, 2022. The increase in general and administrative expenses is primarily attributable to a £7.3 million increase in salary and staff related costs associated with the growth of the business being offset by automation and cost efficiency measures.
Foreign Exchange (Losses)/Gains. Foreign exchange (losses)/gains for the year ended December 31, 2023 were a loss of £1.5 million, as compared to a gain of £33.6 million for the year ended December 31, 2022. The loss for the year ended December 31, 2023 has arisen primarily as a result of the impact of the U.S. Dollar weakening relative to the Pound Sterling on our U.S. dollar denominated cash, short term bank deposits and trade receivables.
Loss on Forward Contracts. In April 2022, we entered into a series of forward contracts of under three months' duration whereby a commitment was made to exchange U.S. dollars for a fixed number of pounds sterling in order to hedge our exposure to foreign exchange risk. The U.S. dollar strengthened during the period relative to the rates agreed as part of the forward contract arrangements, resulting to a loss in the period ended December 31, 2022 of £11.3 million in relation to these transactions. We do not utilise derivative financial instruments for speculative purposes.
Other Income. Other income for the year ended December 31, 2023 was £6.6 million, as compared to £5.7 million for the same period ended December 31, 2022. The increase in other income was primarily due to the U.K. RDEC tax credit which has increased as a result of increases in the underlying rate at which the income is generated, which increased from 13% to 20% on April 1, 2023.
Net Finance Income/(Expense). Net finance income for the year ended December 31, 2023 was £15.6 million, as compared to £5.3 million of net finance income during the same period ended December 31, 2022. The increase is primarily due to increased interest on bank deposits as a result of increasing interest rates throughout the last year.
Share of Loss of Joint Ventures.Share of loss of joint ventures for the year ended December 31, 2023 were £1.6 million, as compared to £0.7 million during the period ended December 31, 2022 as a result of increased underlying research and development expenditure incurred by the joint venture during the year ended December 31, 2023.
Income Tax Benefit. Income tax benefit for the year ended December 31, 2023 was £16.1 million, as compared to £21.9 million for the same period ended December 31, 2022. Our income tax benefit balance largely consists of research and development tax credits which decreased relative to the prior year due to a decrease in the rate at which the U.K. SME cash credit is claimed from 33.35% prior to April 1, 2023 to 18.6% from that date onwards.

Comparison of the Results of Operations for the years ended December 31, 2022 and December 31, 2021 can be found in the prior year filing on Form 20-F dated March 23, 2023.

B. Liquidity and Capital Resources
Sources of Liquidity. Since our inception, we have not generated any revenue from the commercialisation of drug candidates and we have financed our operations through sales of our ordinary and preferred shares in addition to research funding and milestone payments resulting from our partnered programmes. We had cash, cash equivalents and short term bank deposits of £363.0 million and £505.8 million as of December 31, 2023 and 2022, respectively.
As of December 31, 2023, we have raised an aggregate of £533.8 million through the sales of our preferred and ordinary shares net of transaction costs, including £351.3 million ($477.1 million) gross proceeds following the completion of our initial public offering and concurrent private placements.
Our primary uses of capital are, and are expected to continue to be, research and development expenses, compensation and related personnel expenses, and other operating expenses, including facilities. Cash used to fund operating expenses is impacted by the timing of when we pay expenses, as reflected in the change in our outstanding accounts payable and accrued expenses. We expect to incur substantial expenses in connection with the advancement of our drug candidates through the phases of clinical development.
The following table summarises the primary sources and uses of cash and short term bank deposits for each period presented (in thousands):
Year ended December 31,
202320232022
Net cash flows used in operating activities $(149,861)£(117,602)£(60,515)

Net cash flows used in financing activities (4,331)(3,399)(3,998)
Net (decrease)/increase in cash and cash equivalents$(181,603)£(142,512)£(187,194)

Net (decrease)/increase in cash, cash equivalents and short term bank deposits including foreign exchange gains/(losses) on cash and cash equivalents$(181,921)£(142,762)£(56,362)
Operational Activities. Net cash outflows from operating activities totalled £117.6 million for the year ended December 31, 2023 compared to £60.5 million for the year ended December 31, 2022. The increase in net cash outflows from operating activities is primarily as a result of a reduction in cash inflows from collaborations from £91.9 million in the prior year to £22.2 million during the year ended December 31, 2023, as well as working capital movements including a net £14.3 million cash outflow relating to a decrease in trade payables as a result of the timing of payments made within the year ended December 31, 2023 relative to the year ended December 31, 2022.
Cash inflows from collaborations during the year ended December 31, 2023 include £13.6 million from Merck KGaA, Darmstadt, Germany relating to the collaboration agreement signed with that party on September 19, 2023, £3.2 million received upon achievement of a research milestone in the Group's collaboration with Sanofi, and £1.9 million received in relation to the Group's grant with Open Philanthropy Project LLC.
149

We expect that our cash inflows will continue to be highly variable from period to period, primarily due to the structure of our collaboration agreements. These agreements generally include payments to us at inception of the contract and also upon the achievement of milestones, the timing and achievement of which are highly uncertain and difficult to predict.
Investing Activities. Net cash used in investing activities for the year ended December 31, 2023 was £21.5 million, as compared to net cash used of £122.7 million for the year ended December 31, 2022. The majority of the current period net outflow relates to £26.5 million relating to the purchase of property, plant and equipment offset by net inflows of £7.0 million relating to the Group's investments in short term bank deposits.
Financing Activities. Net cash used in financing activities for the year ended December 31, 2023 was £3.4 million, as compared to net cash used of £4.0 million for the same period ended December 31, 2022. The majority of the current period financing cash outflow relates to payments of obligations under lease liabilities.
Funding Requirements. Since our inception, we have incurred significant losses to support the development of our business and in particular, our research and development expenses. We expect to continue to incur significant losses for the foreseeable future and expect our expenses to increase in connection with our ongoing operations, particularly as we advance our product candidates into clinical development and commercialisation.
Based on our current operating plans, we believe that our existing cash, cash equivalents and short term bank deposits and anticipated milestones will be sufficient to fund our operations and capital expenditure requirements well into 2026. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we expect.
It is likely that we will need to obtain additional financing to fund our future operations, including to complete the development and commercialisation of our drug candidates. We are subject to risks related to the development and commercialisation of pharmaceutical products, and we may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business. Our forecast of sufficient financial runway to support our operations is a forward-looking statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors. Our future capital requirements will depend on many factors, including, but not limited to:
progress, timing, scope and costs of our clinical trials, including the ability to timely initiate clinical sites, enrol subjects and manufacture drug candidates for our ongoing, planned and potential future clinical trials;
time and costs required to perform research and development to identify and characterise new drug candidates from our research programmes;
time and costs necessary to obtain regulatory authorisations and approvals that are required to execute clinical trials or commercialise our drug candidates, if approved;
our ability to successfully commercialise our drug candidates, if approved;
our ability to have clinical and commercial products successfully manufactured consistent with the regulations of the U.S. Food and Drug Administration, the European Medicines Agency and other applicable regulatory authorities;
amount of sales and other revenues from drug candidates that we may commercialise, if any, including the selling prices for such potential products and the availability of adequate third-party coverage and reimbursement for patients;
sales and marketing costs associated with commercialising our products, if approved, including the cost and timing of building our marketing and sales capabilities;
terms and timing of any revenue from our existing and future collaborations;
costs of operating as a public company;
time and cost necessary to respond to technological, regulatory, political and market developments;
150

costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights; and
costs associated with, and terms and timing of, any potential acquisitions, strategic collaborations, licensing agreements or other arrangements that we may establish; and
inability of clinical sites to enrol patients as healthcare capacities are required to cope with natural disasters (that could be a result of climate change) or other health system emergencies, such as the COVID-19 pandemic.
The outcome of any of these or other variables with respect to the development of any of our current and future drug candidates could significantly change the costs and timing associated with the development and commercialisation of any drug candidate. Furthermore, our operating plans may change in the future, and we may need additional funds to meet operational needs and capital requirements associated with such operating plans.

E. Critical Material Accounting Policies and Significant Judgements and Estimates
Our consolidated financial statements for the years ended December 31, 2023 and 2022, respectively, have been prepared in accordance with IFRS Accounting Standards as issued by IASB. The preparation of the consolidated financial statements in accordance with IFRS requires the use of estimates and assumptions that affect the value of assets and liabilities — as well as contingent assets and liabilities — as reported on the statement of financial position date, and revenues and expenses arising during the fiscal year. The estimates and associated assumptions are based on information available when the consolidated financial statements are prepared, historical experience and various other factors which are believed to be reasonable under the circumstances, the results of which form the basis of making judgements about the carrying values of assets and liabilities that are not readily apparent from other sources. Judgements and assumptions are primarily made in relation to revenue recognition to determine 1) the appropriate method of identifying the performance obligations under each agreement, 2) the appropriate allocation of revenue to the identified performance obligations, and 3) when variable consideration is considered highly probable to be achieved. Estimates and judgements are also made in relation to the estimated future costs to be incurred in the satisfaction of performance obligations delivered over time, whether the unavoidable future costs of meeting the obligations under customer contracts exceed the economic benefits to be received, the presence of lease arrangements requiring impairment/the recognition of an onerous lease provision, buy-back rights on the Gates Foundation private placement, the fair value of the Group’s investment in GTA and the impairment of goodwill and intangible assets. Existing circumstances and assumptions about future developments, however, may change due to market changes or circumstances arising that are beyond our control. Hence, our estimates may vary from the actual values.
Our significant accounting policies are more fully described in the notes to our consolidated financial statements appearing elsewhere in this annual report. We believe that the following accounting policies are critical to the process of making significant judgements and estimates in the preparation of our consolidated financial statements.
151

Recognition of Revenue. In accordance with IFRS 15, we recognise revenue when our customer obtains control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services. To determine revenue recognition for arrangements that we determine are within the scope of IFRS 15, we perform the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognise revenue when or as we satisfy performance obligations.
At contract inception, we assess the goods or services promised within each contract that falls under the scope of IFRS 15 to identify distinct performance obligations. We then recognise as revenue the amount of the transaction price that is allocated to the respective performance obligation when or as the performance obligation is satisfied. Revenue is measured at the contract price excluding value added tax and other sales taxes.
We include the unconstrained amount of estimated variable consideration in the transaction price. The amount included in the transaction price is constrained to the amount for which it is highly probable that a significant reversal of cumulative revenue recognised will not occur. At contract inception, unconstrained revenue will typically include the upfront payments and in some instances, research funding.
At the inception of each arrangement that includes research, development or regulatory milestone payments, we evaluate whether the milestones (i) relate to the one or more distinct performance obligations under the agreement and (ii) are considered probable of being reached and estimate the amount to be included in the transaction price using the most likely amount method. If it is highly probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within our control or that of the licencee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received.
Any development milestone revenue adjustments are recorded on a cumulative catch-up basis, which would affect revenues and earnings in the period of adjustment.
At the end of each subsequent reporting period, we re-evaluate the estimated variable consideration included in the transaction price and any related constraint and, if necessary, adjust our estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which may affect licence, fees and other revenues and earnings in the period of adjustment.
The transaction price is then allocated to each performance obligation, typically represented by the individual target projects under each collaboration agreements, on a relative stand-alone selling price basis, for which we recognise revenue as or when the performance obligations under the contract are satisfied.
When determining whether performance obligations have been satisfied, progress is measured using the input method utilising either external costs or labour hours incurred depending on the nature of the collaboration arrangement to establish and estimate the progress of completion. Management has determined the input method represents a faithful depiction of our progress towards completion of performance obligations because the time and costs incurred depict the progress of development of the underlying intellectual property which may be transferred to the customer. At the end of each reporting period we re-evaluate costs/hours incurred compared with total expected costs/hours to recognize revenue for each performance obligation. In certain instances expected total cost estimates include estimated costs relating to the substitution of targets where allowed in accordance with a specific collaboration agreement.
Revenue from potential milestones or royalties are typically not recognised at the initiation of a contract. Upfront payments that include performance obligations are recognised as those obligations are delivered.
152

In addition no profit is recognised as costs are incurred until such a time as costs and time to programme completion can be reasonably estimated. As a result of this, until total costs and time to completion can be reliably estimated, a gross loss may be recognised on individual customer contracts despite the expectation that the relevant contract will be profitable overall.
For obligations in which revenue is recognised at a point in time, that point in time is the date at which the title of the goods is transferred to the customer.
Contract liabilities consist of billings or payments received in advance of revenue recognition. Contract assets consist of revenue recognised in advance of billings or payments.
Loss-making collaboration arrangements. For collaborations that meet the criteria under IFRS 15, management judgement is required to determine whether the estimated unavoidable costs of meeting the obligations under each collaboration arrangement exceed the economic benefits expected to be received under it. Where such costs are in excess of our best estimate of future revenues to be generated from the arrangement a provision is recorded in accordance with IAS 37. Management have assessed that no provision for future operating losses is required as at December 31, 2023.
Leases. In December 2022, we entered into a lease arrangement in relation to premises in Miami, Florida, United States, with the lease term due to commence in the first quarter of 2024. Subsequent to entering into the above arrangement, and as a result of our pipeline prioritisation activities, the decision was taken not to occupy these premises, and instead to lease smaller premises nearby. Total minimum lease commitments of £3,040,000 are payable under this arrangement, and as such we must assess whether an onerous contract exists for which a provision is required.
We have engaged an agent to assist in arranging a sublease of the original leased premises to a third party, and have estimated that the present value of the unavoidable costs of meeting our obligations under the contract exceed the expected benefits to be received from subletting the space by £807,000 as at December 31, 2023, with such amount being recorded within provisions at that date.
Gates Foundation Private Placement Buy-back Rights. Under the terms of our private placement with the Gates Foundation, the Gates Foundation has the right to sell, or require us to buy-back, any shareholdings in the Group held by the Gates Foundation at the higher of the public offering price and the market value of the shares if we are in breach of certain terms within the agreement. This right constitutes a derivative financial liability for us which is recognised at fair value through profit and loss. We have assessed the likelihood of a default occurring as low as at December 31, 2023, and as such the fair value of this liability has been estimated as nil at the balance sheet date.
Fair Value of Our Investment in GTA. Equity instruments constitute any contract that evidences a residual interest in the assets of an entity after deducting all of its liabilities.
Following the achievement of a development milestone relating to the our revenue contract with GTA on March 31, 2021, we became entitled to receive a number of ordinary shares and preference shares in this company as non-cash revenue consideration. These shares represent unlisted equity securities and we took the election provided within IFRS9 to recognize fair value gains and losses within Other Comprehensive Income (FVOCI).
GTA is an unlisted early-stage business, with projects in the discovery and development stages of drug development which are pre-revenue generation. As such, the key source of estimation uncertainty is the value per share of these unlisted equity securities. The shares in question are very illiquid, and the primary valuation input is cost or the price of the latest investment where third party share acquisition transactions have taken place adjusted to reflect other factors as appropriate.
153

Goodwill and Pharmacoscopy IP intangible Impairment. On August 18, 2021 we acquired intellectual property with a fair value of £36,078,000 relating to the pharmacoscopy technology utilised by Allcyte as part of the acquisition of that company. The IP is being amortised over a period of 8 years from the acquisition date. Goodwill totalling £5,887,000 was also acquired as part of that acquisition, representing the additional value expected to be derived by us from the acquisition, as well as the assembled workforce.
We assess annually, or whenever there is a change in circumstances, whether goodwill or acquired IP may be impaired. Determining whether an impairment exists requires estimation of the recoverable amount of the Cash Generating Unit ("CGU") to which the goodwill and acquired IP relate, being equal to the higher of its value in use and fair value less costs to sell.
From January 1, 2022 the Group changed its designation of the CGU within which the goodwill and other intangibles relate, with one CGU identified across the Group relating to its drug discovery activities following the integration of the Allcyte business acquired by the Group in August 2021 into the Group’s wider activities during the current year. As at December 31, 2021 the activities of that entity were deemed a separate CGU and the impairment review performed on that basis. This determination constitutes a significant judgement.
The value in use calculation is also judgmental in nature, and requires the Group to make a number of estimates relating to the future cash flows expected to arise from the CGU spanning drug discovery, development, regulatory approval and commercialisation, as well as a suitable discount rate in order to calculate present value. The cash flow projections are further risk adjusted based on observable market comparables to take into account the probability of successfully commercialising a drug at each stage of its development. Sensitivity analysis is performed in order to determine whether reasonable changes in significant assumptions would lead to the carrying value exceeding its recoverable amount. When the carrying value of the CGU exceeds its recoverable amount, the CGU is considered impaired and the assets in the CGU are written down to their recoverable amount. Impairment losses are recognised in the consolidated statement of loss and other comprehensive income.
A detailed impairment assessment was performed as of December 31, 2023, with no impairment noted and no reasonable changes in significant assumptions were identified that would lead to the carrying amount exceeding its recoverable amount.
Internal Control Over Financial Reporting
In connection with this assessment, our management identified the following material weaknesses in our internal control over financing reporting as of December 31, 2023, both of which were identified in the course of preparing our consolidated financial statements for the year ended December 31, 2022:
a.We have not maintained effective process and controls throughout the period, including with respect to consistent review procedures within our financial statement close process to appropriately analyse, record and disclose accounting matters timely and accurately while maintaining appropriate segregation of duties.
b.We did not implement and maintain effective information technology general controls for information systems that are significant to the preparation of our financial statements, including controls to verify that conflicting duties were appropriately segregated within such systems in addition to controls over change management and programme development.
As a result of the material weaknesses described above, our management has concluded that our internal control over financial reporting was not effective at the reasonable assurance level as of December 31, 2023.
154

Managements Plan for Remediation of Current Material Weaknesses. With the oversight of senior management and our audit committee, we continue to evaluate our internal control over financial reporting and are taking several remedial actions to further address the material weaknesses that have been identified, as set forth below:
a.We are in the process of implementing and operating the previously designed information technology general controls, including controls over the maintenance of appropriate segregation of duties.
b.We continue to work with an external professional advisor with sufficient technical accounting expertise to assist us in the implementation and evaluation of internal controls over financial reporting, including the implementation and documentation of formal processes and controls to address the components of the COSO framework, which included formal accounting policies and procedures, maintaining evidence of control operation and segregating duties amongst accounting personnel.
c.We continue to work with an external professional advisor with sufficient technical accounting expertise to assist us in finalizing the design of our financial control environment, including information technology general controls and controls over the maintenance of appropriate segregation of duties.
d.We continue to recruit in order to ensure that we have the necessary expertise and bandwidth within the finance team to address the above material weaknesses, including the hire of senior personnel with significant experience relating to the implementation and execution of information technology general controls, and we will enhance training of our personnel and clearly communicate control responsibilities.
Notwithstanding such material weaknesses, our management has concluded that the financial statements included elsewhere in this Annual Report present fairly, in all material respects, our financial position, results of operations and cash flows for the periods presented in conformity with IFRS.
If we fail to fully remediate the material weaknesses or fail to maintain effective internal controls in the future, it could result in a material misstatement of our financial statements that would not be prevented or detected on a timely basis, which could cause investors to lose confidence in our financial information or cause our stock price to decline. Our independent registered public accounting firm has not assessed the effectiveness of our internal control over financial reporting, which may increase the risk that weaknesses or deficiencies in our internal control over financial reporting go undetected.

Executive Officers
David Hallett, Ph.D., has acted as our Interim Chief Executive Officer and as a member of the board of directors since February 2024. Before that he was our Chief Scientific Officer from February 2023 until February 2024 and our Chief Operations Officer from January 2020 until February 2023. Dr. Hallett has more than two decades of experience in drug discovery and alliance management. Prior to joining Exscientia, Dr. Hallett served as Executive Vice President of Chemistry and Executive Vice President of Alliance Management at Evotec from September 2005 to December 2019. Dr. Hallett trained as a medicinal chemist and served as a Research Fellow at Merck & Co., Inc. He holds a B.A. from the University of Cambridge in Natural Sciences, a Ph.D. from the University of Manchester in Synthetic Organic Chemistry and was a post-doctoral fellow in Synthetic Organic Chemistry at the University of Texas Austin. We believe Dr. Hallett’s experience in drug development and his knowledge of our company qualify him to serve on our board of directors.
Ben Taylor serves as our Chief Financial and Strategy Officer and as a member of the board of directors, having joined Exscientia in November 2020. Mr. Taylor has more than two decades of experience, including 15 years in healthcare investment banking, primarily at Goldman Sachs & Co. LLC, or Goldman Sachs, and seven years in biotech and healthtech executive roles. During this period, Mr. Taylor focused on strategy, financings, communications, clinical development and business development in the biopharmaceutical industry. Prior to joining Exscientia, Mr. Taylor was interim Chief Financial Officer at Aetion, Inc., a healthtech company using real world data analytics to optimise biopharma clinical development and commercialisation, from April 2020 to November 2020. Mr. Taylor served as President and Chief Financial Officer for Tyme Technologies, Inc., where he oversaw operations for the oncology company from April 2017 to August 2020. Mr. Taylor served as Head of Commercial Pharma, Managing Director for Barclays Capital Inc. from February 2016 to March 2017 and in a variety of roles with Goldman Sachs from July 2006 to February 2016. He received a B.A. with Honors from Brown University in East Asian Studies. We believe his extensive experience in the healthcare industry qualifies him to serve on our board of directors.

Ms. Crain holds a B.S. from Arizona State University and an M.B.A. from the Wharton School at the University of Pennsylvania. We believe that Ms. Crain’s experience in finance and business development qualifies her to serve on our board of directors.

Dr. Michor’s laboratory investigates the evolutionary dynamics of cancer initiation, progression, response to therapy, and emergence of resistance. We believe that Dr. Michor’s expertise in oncology and computational biology qualifies her to serve on our board of directors.

Non-Executive Director Appointment Letters
Non-executive directors are engaged on letters of appointment that set out their duties and responsibilities.

Under the non-executive director appointment letters, our non-executive directors are entitled to receive annual fees in accordance with our non-executive director remuneration policy as described below, and in each case inclusive of fees payable for all duties.
Non-Executive Director Remuneration Policy
In August 2021, following advice from its compensation consultant, our board of directors adopted a non-executive director remuneration policy.

Under this policy, we will pay each of our non-executive directors a cash retainer for service on our board of directors and committees of our board of directors. The annual cash compensation amount set forth below is payable to eligible directors under the policy in equal quarterly instalments, payable in arrears on the last day of each fiscal quarter in which the service occurred.
If an eligible director joins our board of directors or a committee of our board of directors at a time other than effective as of the first day of a fiscal quarter, each annual retainer set forth below will be pro-rated based on days served in the applicable fiscal year, with the pro-rated amount paid for the first fiscal quarter in which the eligible director provides the service and regular full quarterly payments thereafter.
All annual retainers are vested upon payment. At their election, eligible directors residing in the United Kingdom will be paid the applicable amounts converted from U.S. dollars to pounds sterling at the time of payment.
Directors are eligible to receive cash compensation as follows:
Annual Board of Directors Service Retainer:

All share options granted under this policy will be nonstatutory stock options, with an exercise price per share equal to 100% of the fair market value (as such term is defined in our 2021 EIP) of the underlying shares on the date of grant, and a term of ten years from the date of grant, subject to earlier termination in connection with a termination of service (as such term is defined in our 2021 EIP).

Initial Grant
Each eligible director who is first elected or appointed to our board of directors, will automatically, and without further action by our board of directors or the Remuneration Committee of our board of directors, upon the date of his or her initial election or appointment to be an eligible director (or, if such date is not a market trading day, the first market trading day thereafter), be granted equity awards in respect of an estimated $500,000 of ordinary shares to be delivered in equal proportions of options and restricted stock units unless the eligible director requests to be granted a greater proportion of options, or the Initial Grant. The shares subject to each Initial Grant will vest in equal monthly instalments over a three-year period such that the option or restricted stock is fully vested on the third anniversary of the date of grant; provided, that the eligible director continues to be a service provider (as such term is defined in our 2021 EIP) through each such vesting date.
Annual Grant
At the close of business on the date of each of our annual general meetings, each eligible director who continues to serve as a non-employee member of our board of directors at such time will be automatically, and without further action by our board of directors or the Remuneration Committee of our board of directors, be granted an equity award in respect of an estimated $250,000 of ordinary shares to be delivered in equal proportions of options and restricted stock units unless the eligible director requests to be granted a greater proportion of options, or the Annual Grant. The shares subject to the Annual Grant will vest at the earlier of (i) the one-year anniversary of the date of grant and (ii) the day immediately prior to the date of our next annual general meeting; provided, that the eligible director continues to be a service provider (as defined in the 2021 EIP) through such vesting date.
Vesting

The principal features of our equity incentive plans are summarised below. These summaries are qualified in their entirety by reference to the actual text of the plan, each of which are filed as exhibits to this annual report.
Equity Incentive Plans
We have granted options and equity incentive awards under our: (1) 2019 Company Share Option Plan, as amended, or the 2019 CSOP; (2) 2018 Unapproved Share Option Plan, as amended, or the 2018 USOP; (3) RSU sub-plan to the 2018 USOP; and (4) 2016 Enterprise Management Incentive Plan, or the 2016 EMI Plan. No further options or awards will be granted under these plans, or the Legacy Plans, following the adoption of the 2021 Equity Incentive Plan, or the 2021 EIP. We have also granted options and equity incentive awards under the 2021 EIP.
The principal features of our equity incentive plans are summarised below. These summaries are qualified in their entirety by reference to the actual text of the applicable plan, which is filed as exhibits to the registration statement of which this annual report is a part.

2021 Equity Incentive Plan
The 2021 EIP was originally adopted by our board of directors on August 11, 2021 and allows for the grant of equity-based incentive awards to our employees and directors, including directors who are also our employees. The material terms of the 2021 EIP are summarised below.
Eligibility and Administration. Our employees, executive directors and employees of our subsidiaries are eligible to receive awards under the 2021 EIP. Our consultants, and non-executive directors and those of our subsidiaries, are eligible to receive awards under the Non-Employee Sub-Plan to the 2021 EIP described below. Our U.K. employees who meet the criteria under the Company Share Option Plan, or CSOP, regime, including that they do not have a material interest in our company (being either beneficial ownership of, or the ability to control directly or indirectly, more than 30% of our ordinary share capital) may be granted options under the CSOP Sub-Plan to the 2021 EIP described below. CSOP options can only be granted for so long as we continue to meet the criteria under the CSOP regime. Persons eligible to receive awards under the 2021 EIP (including the Non-Employee Sub-Plan and the CSOP Sub-Plan) are together referred to as service providers below.
Except as otherwise specified, references below to the 2021 EIP include the Non-Employee Sub-Plan and the CSOP Sub-Plan.
The 2021 EIP is administered by our board of directors, which may delegate its duties and responsibilities to one or more committees of our directors and/or officers (referred to as the Plan Administrator below), subject to certain limitations imposed under the 2021 EIP, and other applicable laws and Nasdaq rules. The Plan Administrator has the authority to take all actions and make all determinations under the 2021 EIP, to interpret the 2021 EIP and award agreements and to adopt, amend and repeal rules for the administration of the 2021 EIP as it deems advisable. The Plan Administrator also has the authority to determine which eligible service providers receive awards, grant awards, set the terms and conditions of all awards under the 2021 EIP, including any vesting and vesting acceleration provisions, subject to the conditions and limitations in the 2021 EIP.

Table of Contents
Shares Available for Awards.The maximum number of ordinary shares, or the Share Reserve, that was reserved for issuance under our 2021 EIP and approved by our shareholders on 15 September 2021, or the Share Reserve, was 10,479,300 ordinary shares (not including any ordinary shares that have become available under the Legacy Plans, as described below). No more than 20,126,700 ordinary shares may be issued under the 2021 EIP upon the exercise of Incentive Share Options (ISO limit). In addition, the number of ordinary shares reserved for issuance under our 2021 EIP automatically increases on January 1 of each year, commencing on January 1, 2022 and ending on (and including) January 1, 2031, in an amount equal to 5% of the total number of ordinary shares outstanding on December 31 of the preceding calendar year, each an Annual Evergreen Increase. Our board may act prior to January 1 of a given year to provide that there will be no increase for such year or that the increase for such year will be a lesser (but not greater) number of ordinary shares. Ordinary shares issued under the 2021 EIP may be new shares, shares purchased on the open market or treasury shares.
If an award under the 2021 EIP expires, lapses or is terminated, exchanged for cash, surrendered, repurchased, cancelled without having been fully exercised or forfeited, any unused shares subject to the award will, as applicable, become or again be available for new grants under the 2021 EIP, or Recycling.
If an option granted under the Legacy Plans prior to its effective date expires, lapses or is terminated, exchanged for cash, surrendered, repurchased, cancelled without having been fully exercised or forfeited on or after its effective date, any unused shares subject to the option will, as applicable, become available for new grants under the 2021 EIP and shall be added to the Share Reserve or will be subject to Recycling, up to a maximum of 9,647,400 ordinary shares. As at December 31, 2023, the Share Reserve was 22,660,786 (being the Share Reserve described above plus any Annual Evergreen Increases) plus 2,923,464 shares that became available as a result of Recycling
The table below presents a breakdown of historic employee share plan usage as at December 31, 2023;

Awards granted under the 2021 EIP in substitution for any options or other equity or equity-based awards granted by an entity before such entity’s merger or consolidation with us or our acquisition of such entity’s property or stock will not reduce the number of ordinary shares available for grant under the 2021 EIP, but will count against the maximum number of ordinary shares that may be issued upon the exercise of Incentive Stock Options.
Options granted under the CSOP Sub-Plan are subject to individual and overall limits as specified by the CSOP regime from time to time.
References in this summary to ordinary shares include an equivalent number of our ADSs.

Awards
The 2021 EIP provides for the grant of options (which may be market value or otherwise, subject to local laws), share appreciation rights (which may be market value or otherwise, subject to local laws), or SARs, restricted shares, restricted share units, or RSUs, and other share-based awards. All awards under the 2021 EIP will be set forth in award agreements, which will detail the terms and conditions of awards, including any applicable vesting and payment terms, change of control provisions and post-termination exercise limitations. A brief description of each award type follows.
Options and SARs. Options provide for the purchase of our ordinary shares in the future at an exercise price set at no less than the nominal value (market value in the case of participants subject to taxation in the United States or options granted under the CSOP Sub-Plan) of an ordinary share on the grant date. SARs entitle their holder, upon exercise, to receive from us an amount equal to the appreciation of the shares subject to the award between the grant date and the exercise date. The Plan Administrator will determine the number of shares covered by each option and SAR, and the conditions and limitations applicable to the exercise of each option and SAR. Only options may be granted under the CSOP Sub-Plan.
Restricted Shares and RSUs. Restricted shares are an award of non-transferable ordinary shares that remain forfeitable unless and until specified conditions are met and which may be subject to a purchase price. RSUs are contractual promises to deliver our ordinary shares in the future, which may also remain forfeitable unless and until specified conditions are met. The Plan Administrator may provide that the delivery of the shares underlying RSUs will be deferred on a mandatory basis or at the election of the participant. The terms and conditions applicable to restricted shares and RSUs will be determined by the Plan Administrator, subject to the conditions and limitations contained in the 2021 EIP.
Other Share-based Awards. Other share-based awards are awards of fully vested ordinary shares and other awards valued wholly or partially by referring to, or otherwise based on, our ordinary shares or other property. Other share-based awards may be granted to participants and may also be available as a payment form in the settlement of other awards, as standalone payments and as payment in lieu of compensation to which a participant is otherwise entitled. The Plan Administrator will determine the terms and conditions of other share-based awards, which may include any purchase price, performance goal, transfer restrictions and vesting conditions.
Performance Criteria. The Plan Administrator may set performance goals in respect of any awards in its discretion.
Certain Transactions. In connection with certain corporate transactions and events affecting our ordinary shares, including a change of control, another similar corporate transaction or event, the Plan Administrator has broad discretion to take action under the 2021 EIP. This includes cancelling awards for cash or property, accelerating the vesting of awards, providing for the assumption or substitution of awards by a successor entity, adjusting the number and type of shares subject to outstanding awards and/or with respect to which awards may be granted under the 2021 EIP and replacing or terminating awards under the 2021 EIP. In addition, in the event of certain equity restructuring transactions, the Plan Administrator will make equitable adjustments to the limits under the 2021 EIP and outstanding awards as it deems appropriate to reflect the transaction. The treatment of CSOP options in connection with such a transaction is subject to the requirements of the CSOP regime.

Table of Contents
Plan Amendment and Termination. Our board of directors may amend or terminate the 2021 EIP at any time; however, no amendment, other than an amendment that increases the number of shares available under the 2021 EIP, may materially and adversely affect an award outstanding under the 2021 EIP without the consent of the affected participant and shareholder approval will be obtained for any amendment to the extent necessary to comply with applicable laws. The 2021 EIP will remain in effect until the tenth anniversary of its effective date unless earlier terminated by our board of directors. No awards may be granted under the 2021 EIP after its termination.
Transferability and Participant Payments. Except as the Plan Administrator may determine or provide in an award agreement, awards under the 2021 EIP are generally non-transferrable, except to a participant’s designated beneficiary, as defined in the 2021 EIP. With regard to tax and/or social security withholding obligations arising in connection with awards under the 2021 EIP, and exercise price obligations arising in connection with the exercise of options under the 2021 EIP, the Plan Administrator may, in its discretion, accept cash, wire transfer or check, our ordinary shares that meet specified conditions, a promissory note, a “market sell order,” such other consideration as the Plan Administrator deems suitable or any combination of the foregoing, subject, in the case of CSOP options, to the requirements of the CSOP regime.
Non-U.S. and Non-U.K. Participants. The Plan Administrator may modify awards granted to participants who are non-U.S. or U.K. nationals or employed outside the U.S. and the U.K. or establish sub-plans or procedures to address differences in laws, rules, regulations or customs of such international jurisdictions with respect to tax, securities, currency, employee benefit or other matters or to enable awards to be granted in compliance with a tax favourable regime that may be available in any jurisdiction.
Non-employee Sub-plan. The Non-employee Sub-plan governs equity awards granted to our non-executive directors, consultants, advisers and other non-employee service providers and provides for awards to be made on identical terms to awards made under our 2021 EIP.


Legacy Plans
2019 Company Share Option Plan
Overview
The 2019 CSOP was adopted on November 27, 2019, as amended on April 3, 2021 and is intended to qualify as a “company share option plan” that meets the requirements of Schedule 4 to the Income Tax (Earnings and Pensions) Act 2003, or ITEPA. Options granted under the 2019 CSOP are potentially U.K. tax favoured options up to an individual limit of £30,000 calculated by reference to the market value of the shares under option at the date of grant.
Options granted under the 2019 CSOP must have an exercise price equal to or more than the market value of a share on the date of grant and, where the exercise of an option is to be satisfied by newly issued shares, the exercise price must not be less than the nominal value of a share.
Participation/Eligibility and Administration. Options granted under the 2019 CSOP are granted by the board of directors in its absolute discretion to employees that qualify to be granted an option under Schedule 4 of ITEPA.
169

Table of Contents
Vesting and Exercise of Options. Options granted under the 2019 CSOP may be granted subject to a vesting schedule containing one or more time-based conditions and additionally, or in the alternative, specific performance conditions that must be met before all or part of an option can be exercised. The board of directors has discretion to determine whether and the extent to which a performance condition has been satisfied.
The board of directors may vary or waive one or more performance conditions attaching to an option, provided that such variation to a performance condition can only be effected by the board of directors if an option becomes exercisable before the end of the period over which the original performance condition was to be assessed or it reasonably considers that the performance condition is no longer an appropriate measure of performance. Such varied performance condition must be no more difficult to satisfy than when the original performance condition was set and not materially easier to satisfy than the original performance condition was at the original option’s grant date.
Options granted under the 2019 CSOP may not be exercised after the tenth anniversary of the date of grant and generally may only be exercised on the earliest of (1) the company coming under the control (as defined in section 719 ITEPA) of another person; (2) a court sanctioned scheme of arrangement; (3) shareholders becoming bound by a non-U.K. reorganisation; or (4) a person becoming bound or entitled to acquired shares under sections 979 to 985 of the Companies Act; or (5) the vesting conditions specified in the applicable option agreement being met. Options may also be exercised by certain by participants that cease to be employed by us. See “Cessation of Employment” below.
Terms Generally Applicable to Options. Save for transferring an option to a deceased option holder’s personal representative on their death, options granted under the 2019 CSOP cannot be transferred, assigned or have any charge or other security created over them.
Options granted under the 2019 CSOP will lapse on the earliest of the following:
an attempt to transfer, assign or encumber the option (save for a transfer to a personal representative on death);
a performance condition failing to be met that results in the entire option being incapable of exercise;
the lapse date stated in the relevant option agreement;
the first anniversary of an option holder’s death;
the day after the option holder ceases to be an employee or director of the company if the options were unvested, save that:
if cessation of employment is due to injury, ill-health, disability, a transfer of one of our businesses out of the group, retirement or redundancy (within the meaning of the Employment Rights Act 1996), options will be exercisable for six months after cessation of employment; and
our board of directors may determine within 90 days of cessation of employment that options may remain exercisable for a specified period of time post-cessation of employment;
90 days after the option holder ceases to be employed by the company if the options were vested and cessation of employment was not due to summary dismissal;
six months after the company coming under the control (as defined in section 719 ITEPA) of another person; (2) a court sanctioned scheme of arrangement; or (3) shareholders becoming bound by a non-U.K. reorganisation;
six months after a reorganisation of the company if a replacement option is offered in the acquirer as part of the reorganisation; or
the option holder becoming bankrupt.

170

Table of Contents
Cessation of Employment. If an option holder that holds an unvested option ceases to be employed by us, their option will lapse and cease to be exercisable on the day after the option holder ceases to be employed by the company unless:
cessation of employment is due to injury, ill-health, disability, a transfer of one of our businesses out of the group, retirement or redundancy (within the meaning of the Employment Rights Act 1996), in which case the option will be exercisable for six months after cessation of employment; or
our board of directors determine within 90 days of cessation of employment that the option may remain exercisable for a specified period of time post-cessation of employment.
If an option holder that holds a vested option ceases to be employed by the company and such cessation of employment was not due to summary dismissal, they may exercise their vested option for a period of 90 days after cessation of employment, after which, the option will lapse.
If an option holder ceases to be employed by reason of summary dismissal, the option shall not be capable of exercise unless our board of directors determine within 90 days of cessation of employment that the option may remain exercisable for a specific period of time post-cessation of employment.
Corporate Transactions. If (1) a person or entity acquires control (as defined in section 719 ITEPA) of the company, (2) a court sanctions a scheme of arrangement or (3) shareholders become bound to a non-U.K. reorganisation, option holders shall be entitled to exercise their options in whole or in part within the period of six (6) months beginning with the date when such relevant event occurs, and to the extent that an option is not exercised within such period it shall lapse and cease to be exercisable. However, in anticipation of the completion of any of the events described in clauses (1) through (3) above, the board of directors may in its absolute discretion make arrangements to permit outstanding options to be exercisable during a period of 20 days ending immediately before such event occurs. If options are not exercised within this period, they shall lapse immediately upon expiry of such period.
A change of control will not trigger a right to exercise options in a scenario in which the acquirer is an entity under which the ultimate beneficial ownership of the remains the same and such entity offers a replacement option to the option holders. If a replacement option is not accepted by option holders in this scenario, their options will lapse six months after the change of control.
Amendments to 2019 CSOP. The board of directors can amend the 2019 CSOP from time to time save that such amendments (1) cannot be made if it would mean that the 2019 CSOP would no longer qualify under Schedule 4 of ITEPA; (2) cannot be made without option holders’ prior written consent if the amendment would have a material impact on their rights; or (3) require certain investor approvals if the amendment would (a) make existing options grants materially more generous; (b) increase option limits; or (c) expand the class of employees eligible to participate in the 2019 CSOP.

2018 Unapproved Share Option Plan
Overview
The 2018 USOP was adopted on February 13, 2018 and amended on September 25, 2019 and April 1, 2021, and provides for the grant of options over Ordinary shares or B Ordinary Shares (or an equivalent number of our ADSs) in the capital of the company.
Participation/Eligibility and Administration. Options granted under the 2018 USOP are granted by the board of directors to individuals.
171

Table of Contents
Vesting and Exercise of Options. Options granted under the 2018 USOP may be granted subject to such vesting and exercise conditions as contained in the option agreement relating to such option.
Save where the context otherwise permits, or if otherwise determined by the board of directors, a vested option shall be capable of exercise on any business day. Options granted under the 2018 USOP may be exercised in whole or in part provided that, on any day, an option may be exercised over no fewer than the less of 25% of the vested shares, the total number of shares that remain exercisable at the time, and such other number as the board of directors may determine.
Options can potentially also be exercised by option holders if they cease to be employed or engaged. See “Cessation of Employment/Engagement” below.
Terms Generally Applicable to Options. Save for transferring an option to a deceased option holder’s personal representative on their death, options granted under the 2018 USOP cannot be transferred, assigned or have any charge or other security created over them.
Options granted under the 2018 USOP will lapse on the earliest of the following:
the tenth anniversary of the date of grant;
an attempt to transfer, assign or encumber the option (save for a transfer to a personal representative on death);
the first anniversary of an option holder’s death;
the date of cessation of employment or engagement if the option holder is a Bad Leaver (as defined below);
if the option holder is a Good Leaver (as defined below):
90 days after the date of cessation of employment or engagement in respect of the portion of the option that is exercisable on cessation (or 12 months if the Good Leaver reason is the death of the option holder); and
the date of cessation of employment or engagement in respect of the portion of the option that is not exercisable on cessation;
60 days after the completion of an asset sale or a share sale resulting in a change of control (or immediately after completion if option holders are given the opportunity to exercise their options by the board of directors prior to completion); or
the option holder becoming bankrupt.
Cessation of Employment/Engagement. If an option holder ceases to be employed or engaged with us and:
they are a Good Leaver, then:
the portion of the option that is exercisable on cessation shall be exercisable for up to 90 days after the date of cessation of employment or cessation (or 12 months if the Good Leaver reason is the death of the option holder); and
the portion of the option that is not exercisable on cessation shall lapse on the date of cessation; and
they are Bad Leaver, the option shall lapse in full on the date of cessation.
For the purposes of the 2018 USOP:
“Good Leaver” means an option holder that becomes a leaver as a result of : (a) injury, ill-health or disability (evidenced to the reasonable satisfaction of the board of directors); (b) retirement; (c) redundancy within the meaning of the Employment Rights Act 1996; (d) death; (e) employment being solely with a company which is not the company or one of its subsidiaries or their employment being transferred to a person who is not a member of the company or one of its subsidiaries on completion of the sale of the business or part of the business to which their employment relates; or (f) the board of directors declaring the option holder a Good Leaver in its absolute discretion. “Bad Leaver” means a leaver that is not a Good Leaver.

Table of Contents
Corporate Transactions. If a person makes an offer for the company that results in a company reorganisation, an asset sale or a majority share sale giving rise to a change of control, the board of directors may in its absolute discretion and by notice in writing to all option holders declare all outstanding options to be exercisable in full during a period specified by the board of directors not exceeding three (3) months (and which period shall end immediately before the acquirer obtains control of the company if it has not already ended). If options are not exercised within this period, they shall lapse immediately upon expiry of such period. If no notice is given to the option holders, options shall lapse 60 days after the completion of a company reorganisation, asset sale or share sale resulting in a change of control.
In the event of the establishment of a new holding company, options shall be substituted for equivalent options over shares in the new holding company.
Amendments to 2018 USOP. The board of directors can make minor alterations or additions to the 2018 USOP from time to time to benefit the administration of the 2018 USOP, to take account of changes in legislation or to obtain or maintain favourable taxation or regulatory treatment for participants.
RSU Sub-plan to the 2018 Unapproved Share Option Plan. The RSU Sub-plan governs the terms of restricted stock unit awards, or RSUs, may be granted under the RSU Sub-Plan to the 2018 USOP. RSUs are contractual promises to deliver our ordinary shares or ADSs in the future and are subject to substantially the same terms to options granted under the 2018 USOP.
In connection with certain corporate transactions and events affecting our ordinary shares, including a change of control, another similar corporate transaction or event, our board of directors has broad discretion to take action under the RSU Sub-Plan. This includes cancelling RSUs for cash or property, accelerating the vesting of RSUs, providing for the assumption or substitution of RSUs by a successor entity, adjusting the number and type of shares subject to outstanding RSUs and replacing or terminating RSUs.

2016 Enterprise Management Incentive Plan
Overview
The 2016 EMI Plan was adopted on February 29, 2016 and is intended to qualify as an “enterprise management incentive,” or EMI, plan that meets the requirements of Schedule 5 to ITEPA.
The 2016 EMI Plan is operated on the same terms as the 2018 USOP but with the following differences:
Participation/Eligibility and Administration. Notwithstanding the company and option requirements, an individual is eligible to be granted EMI options under the 2016 EMI Plan if they satisfy the employee requirements of Schedule 5 to ITEPA.
Vesting and Exercise of Options. In addition to the terms described above for the 2018 USOP, the board of directors may in its absolute discretion declare an option to be exercisable to such extent as it determines upon the occurrence of a disqualifying event, as set out in sections 533-539 of ITEPA.
Corporate Transactions. In addition to the terms described above for the 2018 USOP, where there is a company reorganisation that includes the creation of a new holding company which has substantially the same identity and proportion of shareholders and such new holding company offers a replacement option to participants of the 2016 EMI Plan, options shall not be exercisable in connection with the aforesaid company reorganisation.

Insurance and Indemnification
To the extent permitted by the Companies Act, we are empowered to indemnify our directors against any liability they incur by reason of their directorship. We maintain directors’ and officers’ insurance to insure such persons against certain liabilities and have entered into a deed of indemnity with each of our directors and executive officers .
Insofar as indemnification of liabilities arising under the Securities Act may be permitted to our board, executive officers or persons controlling us pursuant to the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

C. Board Practices
Composition of Our Board of Directors
Our board of directors is composed of six members. As a foreign private issuer, under the listing requirements and rules of Nasdaq, we are not required to have independent directors on our board of directors, except that our audit committee is required to consist fully of independent directors. Our board of directors has determined that Elizabeth Crain, Robert Ghenchev and Franziska Michor, each of whom serve on our board of directors, do not have a relationship that would interfere with the exercise of independent judgement in carrying out the responsibilities of director and that each of these directors is “independent” as that term is defined under Nasdaq rules.
In accordance with our articles of association, one-third of our directors will retire from office at each annual general meeting of shareholders. See “Item 10.B – Additional Information – Memorandum and Articles of Association — Appointment of Directors, Classification and Reappointment of Directors.” At each annual general meeting, the directors whose terms expire will retire and are eligible for re-appointment by ordinary resolution at such annual general meeting. At each annual general meeting, the successors to directors whose terms then expire or the directors who have been re-appointed will be elected to serve from the time of election and qualification until the third annual meeting following election. Our directors are divided among the three classes as follows:
Class I consists of Robert Ghenchev and Franziska Michor whose terms will expire at our annual general meeting held in 2025;
Class II consists of Mario Polywka and Elizabeth Crain whose terms will expire at our annual general meeting held in 2026; and
Class III consists of Ben Taylor and David Hallett whose terms will expire at our annual general meeting held in 2024.
Each director shall serve until his or her successor is duly elected and qualified or until his or her earlier death, resignation or removal.

B. Related Party Transactions
Arrangements with Evotec
Evotec SE, or, together with its affiliates, Evotec, is a beneficial owner of more than 10% of our share capital. Mario Polywka, DPhil, a member of our board of directors, is the interim Chief Executive Officer of Evotec and is a current member of its Supervisory Board. Initially, our collaborations with Evotec were aimed at designing dual CD73/ A2A- and CD73-inhibitor compounds. Our collaborative projects developed from that point.
We and our subsidiaries have entered into the following commercial arrangements with Evotec:
Collaboration Agreement and Services. Under the terms of a collaboration agreement with Evotec, we engaged Aptuit (Verona) SRL (an affiliate of Evotec) to carry out the preclinical toxicology and manufacturing work for EXS21546. We shared the costs of this arrangement equally with Evotec. In connection with this arrangement, we have received invoices from Evotec totalling £1,039,000 and £1,133,000 in the years ended December 31, 2021 and 2022 respectively, and credit notes totalling £687,000 in the year ended December 31, 2023.
Drug Discovery Services Agreement. In November 2017, we entered into a drug discovery services agreement, or the Evotec Discovery Agreement, with Evotec to procure its drug discovery services, including those related to the development of assays, screening, structural biology and medicinal chemistry.
In October 2020, we amended the Evotec Discovery Agreement to extend its term to November 2022 and in September 2022 we extended its turn to April 2023. Before that time, either party may terminate specific projects if those resources are to be immediately redeployed, and we may additionally terminate any project under the agreement without cause by providing 90 days’ prior written notice. The Evotec Discovery Agreement stipulates that upon our request, for each planned project, Evotec shall provide reasonably detailed estimates of the services, time frame, deliverables and pricing for such project. Once agreed to by both parties, each project will be overseen by a steering committee comprised of an equal number of representatives from each party. Subject to certain limited exceptions, we retain ownership over all intellectual property discovered or made by Evotec in the course of its performance of the services under the Drug Discovery Services Agreement, and to the extent that any rights in such intellectual property cannot be assigned to us by Evotec, they have provided to us a perpetual, irrevocable, worldwide, royalty-free, exclusive, transferable licence, sublicensable through multiple tiers, to practice such non-assignable rights in any manner for any purpose.
We have engaged Evotec and its affiliates to provide services on several projects under this agreement, the most material of which is an engagement to provide CRO services to help us deliver candidate compounds under one of our collaboration agreements with Celgene Corporation and BMY which commenced in 2019 and 2021, respectively. In connection with these CRO services projects, we have received invoices totalling £13,870,000, £8,485,000, and £3,341,000 in the years ended 2021, 2022 and 2023, respectively. For all other projects provided under the Evotec Discovery Agreement, we have received invoices totalling £130,000, £273,000 and £1,597,000 in the years ended 2021, 2022 and 2023, respectively.

Compound Management Services Agreement. In April 2021, we entered into a compound management services agreement, or the Evotec Compound Management Agreement, with Evotec to procure compound management services, including those related to compound reception, storage, maintenance while in storage, quality analysis and control, and shipment.
The Evotec Compound Management Agreement is effective for a five-year term, though either party may terminate the agreement without cause by providing 90 days’ prior written notice. Under the Evotec Compound Management Agreement we may engage Evotec’s compound management services by agreeing to the terms of a work order detailing the services, obligations and other material terms. Subject to certain limited exceptions, we retain ownership over all final products and intellectual property discovered or made by Evotec in the course of its performance of the services under the agreement and, if required, Evotec will take actions necessary or appropriate to establish, register, assign or otherwise record our ownership. During the term of the Evotec Compound Management Agreement, we grant to Evotec a royalty-free, fully paid-up, worldwide, non-exclusive licence to use any relevant intellectual property owned by, or licenced to us, to the extent necessary for Evotec to perform its services under the agreement.
We have engaged Evotec to provide general services related to powder and solution compound transfer, reception, identification, inventory registration, quality analysis and control, storage, maintenance while in storage and shipment to our sites and partners. In connection with this arrangement, we have paid Evotec £231,000, £231,000 and £228,000 in the years ended December 31, 2021, 2022 and 2023 respectively.

Agreements with Our Executive Officers and Directors and their Close Family Members
We have entered into service agreements with our non-employee directors, executive officers, and with David Hallett and Ben Taylor, our executive directors. See “Item 6 – Directors, Senior Management and Employees.” These agreements contain customary provisions and representations, including confidentiality, non-competition, non-solicitation and inventions assignment undertakings by our executive officers and our executive directors. However, the enforceability of the non-competition provisions may be limited under applicable law.
Since November 2016, Iva Navratilova, Ph.D., the spouse of our former Chief Executive Officer, Andrew Hopkins, has been employed by us. She is currently our Vice President of Biophysics and receives a salary and benefits consistent with her position in our company and market practices.

Indemnification Agreements
We have entered into our standard deed of indemnity with our directors and executive officers, including with Franziska Michor in connection with her appointment to our board of directors in May 2023. Our articles of association empower us to indemnify our directors and executive officers to the fullest extent permitted by applicable law. See “Item 6 – Directors, Senior Management and Employees.”

Related Person Transaction Policy
We have adopted a related person transaction policy that sets forth our procedures for the identification, review, consideration and approval or ratification of related person transactions. For purposes of our policy only, a related person transaction is a transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we or any of our subsidiaries and any related person are, were or will be participants in which the amount involved exceeds $120,000 or which is unusual in its nature or conditions. Transactions involving compensation for services provided to us as an employee or director are not covered by this policy. A related person is any executive officer, director or beneficial owner of more than 5% of any class of our voting securities, including any of their immediate family members and any entity owned or controlled by such persons.
The related person transaction policy also covers related party transactions under the AIM Rules for Companies published by the London Stock Exchange, or the AIM Rules, which contains a different definition of a related party to the definition of a related person set out above for U.S. purposes. The AIM Rules require that any transaction with a related party (pursuant to the definition in the AIM Rules) that exceeds 5% in any of the class tests set out in the AIM Rules, taking into account certain provisions relating to aggregation of transactions, should be announced without delay as soon as the terms of the transaction are agreed, and that the announcement should include certain specified information including a statement that our directors (with the exception of any director who is involved in the transaction as a related party) consider, having consulted with our nominated adviser for AIM, that the terms of the transaction are fair and reasonable insofar as our shareholders are concerned.

Dividend Distribution Policy
Since our incorporation, we have not declared or paid any dividends on our issued share capital. We intend to retain any earnings for use in our business and do not currently intend to pay dividends on our ordinary shares or ADSs. The declaration and payment of any future dividends will be at the discretion of our board of directors and will depend upon our results of operations, cash requirements, financial condition, contractual restrictions, any future debt agreements or applicable laws and other factors that our board of directors may deem relevant. See the section titled “Item 3.D. – Risk Factors–Risks related ownership of our ADSs–We do not intend to pay dividends on our ADSs, so any returns will be limited to the value of our ordinary shares.”
Under the laws of England and Wales, among other things, we may only pay dividends if we have sufficient distributable reserves (as determined on a non-consolidated basis), which are our accumulated realised profits that have not been previously distributed or capitalised less our accumulated realised losses, so far as such losses have not been previously written off in a reduction or reorganisation of capital.

Legal Proceedings
From time to time, we may become involved in legal proceedings arising in the ordinary course of our business. We are not currently subject to any material legal proceedings.

C. Material Contracts
In addition to the contracts described elsewhere in this annual report, the following are summaries of each material contract to which we are a party for the two years preceding the date of this annual report.
BMY Collaboration and Licence Agreement
In May 2021, we entered into a Collaboration and Licence Agreement, or the BMY Agreement, with BMY. Under the BMY Agreement, the parties agreed to collaborate in the discovery and preclinical development of target compounds for collaboration targets. During the term of the BMY Agreement, BMY retains the exclusive right to develop and commercialise target compounds, while we are exclusively responsible for the preclinical manufacturing process.
A joint steering committee, composed of an equal number of members from each party, oversees the work performed under the BMY Agreement. The research plan, which governs the research and development of target compounds under the BMY Agreement, runs for four years from the date on which the research plan commences. BMY retains the right to terminate the research plan upon six months’ prior written notice. Alternatively, BMY may also extend the research plan for an additional year after the initial four-year term.
Under the BMY Agreement, BMY has paid us an up-front amount of $30 million. We are also entitled to payments upon achievement of developmental benchmarks and regulatory and sales milestones. Under the BMY Agreement, we could potentially receive up to $257 million per target, excluding royalties . Additionally, BMY will pay us a range of low to high single digit percentage royalty payments on sales of drug candidates developed pursuant to the agreement, if any, that receive regulatory approval.
Under the BMY Agreement, we granted BMY an exclusive, worldwide, royalty-bearing, sublicensable licence to discover, develop, and commercialise target compounds. Additionally, BMY granted us a non-exclusive, worldwide, non-sublicensable, royalty-free licence solely for the purposes of carrying out our obligations under the BMY Agreement. BMY retained the right to terminate the BMY Agreement entirely or on a country-by-country basis. Either party may terminate the BMY Agreement on a licenced product-by licenced product basis upon a material and uncured breach of the agreement by the other party , except that if BMY materially breaches its diligence obligations and does not cure within a specified period, we can terminate the BMY Agreement on a market-by-market or target-by-target basis.
On March 11, 2022, BMY extended its first collaboration arrangement with the Group by six months in order to generate additional data including the use of translational capabilities for key targets under the collaboration using the Group’s precision medicine platform, in relation to which the Group received a cash payment of $5,000,000 (£3,821,000).
In October 2023, we mutually determined to prioritise certain projects and not to proceed with the development of others within the collaboration.

Gates Global Access Commitments Agreement
On September 1, 2021, we entered into a Global Access Commitments Agreement with the Gates Foundation to expand our pandemic preparedness programme. We have committed to contribute a matching amount of $35.0 million to the collaboration, through operations and funding for third party activities.

Sanofi Licence Collaboration and Licence Agreement
In January 2022, we entered into a Collaboration and Licence Agreement, with Sanofi, or the CLA, and in January 2023, July 2023 and December 2023, we amended the Collaboration and Licence Agreement, with such as amended CLA referred to as the Amended CLA. Pursuant to the Amended CLA, we will use our artificial intelligence-driven, end-to-end integrated platform to discover and validate novel targets in the oncology and immunology therapeutic areas. We will collaborate with Sanofi to advance certain of these targets into small molecule inhibitor drug research projects and accelerate the identification of certain small molecule development candidates.
Sanofi made an upfront cash payment of $100 million to us on signing the CLA and made an additional payment of $4 million in connection with the expansion of the collaboration pursuant to the December 2023 amendment. Under the Amended CLA, Exscientia and Sanofi may initiate up to 15 novel small molecule programmes and additional targets may be added to the collaboration under certain circumstances. Each programme, if successfully researched, developed and/or commercialised, will yield research, clinical development, regulatory, and commercial milestone payments of up to approximately $343 million including up to $193 million in the aggregate for certain specified research, development and regulatory milestones, and up to $150 million in the aggregate for certain specified commercial milestones. The Amended CLA could potentially provide us with up to approximately $5.2 billion in aggregate milestone payments across all 15 potential programmes.
In the case that a therapeutic product resulting from the research collaboration is commercialised, we will also be eligible to receive tiered royalties on net sales ranging from high-single-digits to mid-teens. We also have an option for clinical co-investment which, if exercised, would increase the tiered royalty rates to up to 21% on net sales of co-funded products.
The collaboration may utilise Exscientia’s AI-based capabilities and precision medicine platform from target identification through patient selection. Once a target is identified, Exscientia will be responsible for leading the design, translational and early preclinical studies to determine development candidates. Upon Sanofi’s selection of a compound as a development candidate, Sanofi will be solely responsible for the IND-enabling studies and clinical development, manufacturing and commercialisation of such development candidate at its own cost and expense. Under the Amended CLA, Sanofi has agreed to use commercially reasonable efforts to obtain regulatory approval for at least one qualifying small molecule product in at least one agreed upon major market.
The research component of the collaboration will be overseen by a joint steering committee comprised of an equal number of representatives from each of Exscientia and Sanofi. Exscientia and Sanofi may agree to utilise our precision medicine platform for patient enrichment in Sanofi’s non-small molecule programmes.
Pursuant to the Amended CLA, Exscientia granted to Sanofi an exclusive licence (with the right to grant sublicences through multiple tiers) to the intellectual property that is the subject of each small molecule research programme for all purposes, throughout the world. Sanofi has the right to control the prosecution and maintenance of any patent rights related to intellectual property that is the subject of each small molecule research programme.
187

After the CLA’s effective date, we are subject to varying exclusivity arrangements for specified periods of time which limit our ability to conduct research and development, manufacturing or commercialisation activities (whether ourselves or in conjunction with a third party) with respect to compounds and targets which are within the scope of the Amended CLA and with respect to certain agreed pathways of interest.
The Amended CLA contains standard termination provisions, including for material breach or insolvency and for Sanofi’s convenience. Certain of these termination rights can be exercised in respect of a given target, or in respect of the CLA as a whole. In certain circumstances, upon termination, we have the right to terminate the licences granted to Sanofi and to pursue the development, manufacture and commercialisation of the product candidates.

Merck Research Collaboration Agreement
On September 20, 2023, we entered into a Research Collaboration Agreement, or the RCA, with the Healthcare Business of Merck KGaA, Darmstadt, Germany, referred to as Merck KGaA, Darmstadt, Germany, pursuant to which we will be responsible for the design process, as well as translational and early non-clinical studies to discover development candidates based on the initial agreed targets. Upon Merck KGaA, Darmstadt, Germany’s selection of a compound as a development candidate, Merck KGaA, Darmstadt, Germany will be solely responsible for the non-clinical studies and clinical development, manufacturing and commercialisation of such development candidate at its own cost and expense. Under the RCA, Merck KGaA, Darmstadt, Germany has agreed to use commercially reasonable efforts to obtain regulatory approval for at least one product candidate in certain major markets and to commercialise such product if it receives any such regulatory approval.
The research component of the collaboration will be overseen by a joint steering committee comprised of an equal number of representatives from us and from Merck KGaA, Darmstadt, Germany. The collaboration will also have an IP sub-committee comprised of an equal number of patent attorneys from each party that will be the liaison for intellectual property matters that arise in connection with the collaboration.
The RCA allows Merck KGaA, Darmstadt, Germany and us to identify additional targets in oncology and immunology or other mutually agreed disease areas. Should we identify additional targets for the collaboration, we would be responsible for target validation in addition to drug design.
Merck KGaA, Darmstadt, Germany made an upfront cash payment of $20 million to us on signing the RCA, and we remain eligible to receive up to $674 million in discovery, development, regulatory and sales-based milestones, if all milestones for all three initial programmes are achieved. Of this amount, up to $113 million is potentially payable on milestones achieved in the discovery phase of development. In addition, we will receive royalty payments ranging from mid-single-digits to low-double-digits on net sales of any products resulting from the initial three targets that are commercialised. If any additional target is identified for the collaboration, we would be eligible to receive additional milestone payments on such target.
Pursuant to the RCA, we granted to Merck KGaA, Darmstadt, Germany a worldwide, exclusive, transferable license (with the right to grant sublicenses through multiple tiers) to the intellectual property that is necessary or reasonably useful for development or commercialisation of the target compounds and resulting products, if any, in order to develop, manufacture, commericalise and sell the target compounds and resulting products, if any. Merck KGaA, Darmstadt, Germany has the right to control the prosecution and maintenance of any patent rights related to intellectual property that is the subject of each programme.

Table of Contents
The RCA will remain in effect from September 20, 2023 until such date that no milestone payments or royalties are, or may become, payable under the RCA, unless the RCA is terminated earlier in accordance with its terms. The RCA contains standard termination provisions, including termination by either party for material uncured breach or insolvency of the other party, by us if Merck KGaA, Darmstadt, Germany breaches certain obligations with respect to regulatory and commercialisation activities, and by Merck KGaA, Darmstadt, Germany for convenience. Certain of these termination rights can be exercised in respect of a given target, or in respect of the RCA as a whole. In certain circumstances, upon termination, we have the right to terminate the licences granted to Merck KGaA, Darmstadt, Germany and to pursue the development and commercialisation of the target compounds and resulting products, if any.
During the term of the RCA, we are subject to exclusivity obligations that limit our ability to conduct research and development or commercialisation activities (whether ourselves or in conjunction with a third party) with respect to the compounds and targets which are within the scope of the RCA.
The RCA contains standard confidentiality provisions and representations and warranties made by each party to the agreement. The parties also provide mutual indemnification under the agreement and the RCA excludes liability of either party for consequential or similar damages, except to the extent prohibited by law.


D. Exchange Controls
There are no governmental laws, decrees, regulations or other legislation in the United Kingdom that may affect the import or export of capital, including the availability of cash and cash equivalents for use by us, or that may affect the remittance of dividends, interest, or other payments by us to non-resident holders of our ordinary shares or ADSs, other than withholding tax requirements. There is no limitation imposed by English law or our articles of association on the right of non-residents to hold or vote shares.

Material U.S. Federal Income Tax Considerations for U.S. Holders
The following is a description of certain material U.S. federal income tax consequences generally applicable to U.S. Holders (as defined below) of owning and disposing of our ordinary shares or ADSs. It is not a comprehensive description of all tax considerations that may be relevant to a particular U.S. Holder’s decision to acquire our ordinary shares or ADSs. This discussion applies only to a U.S. Holder that holds our ordinary shares or ADSs as a capital asset for U.S. federal income tax purposes (generally, property held for investment). In addition, it does not describe all of the tax consequences that may be relevant in light of a U.S. Holder’s particular circumstances, including state and local tax consequences, estate and gift tax consequences, alternative minimum tax consequences, the potential application of the Medicare contribution tax on net investment income, the potential application of the special tax accounting rules under Section 451(b) of the Code, and tax consequences applicable to U.S. Holders subject to special rules, such as:
banks, insurance companies and certain other financial institutions;
pension plans;
cooperatives;
U.S. expatriates and certain former citizens or long-term residents of the United States;
dealers or traders in securities who use a mark-to-market method of tax accounting;
189

Table of Contents
persons holding ordinary shares or ADSs as part of a hedging transaction, “straddle,” wash sale, conversion transaction or integrated transaction or persons entering into a constructive sale with respect to ordinary shares or ADSs;
persons whose “functional currency” for U.S. federal income tax purposes is not the U.S. dollar;
brokers, dealers or traders in securities, commodities or currencies;
tax-exempt entities (including private foundations), government organisations or international organisations;
S corporations, partnerships or other entities or arrangements classified as partnerships for U.S. federal income tax purposes (and investors therein);
regulated investment companies or real estate investment trusts;
persons who acquired our ordinary shares or ADSs pursuant to the exercise of any employee stock option or otherwise as compensation;
persons that own or are deemed to own ten percent or more of our shares (by vote or value); and
persons holding our ordinary shares or ADSs in connection with a trade or business, permanent establishment or fixed place of business outside the United States.
If an entity that is classified as a partnership for U.S. federal income tax purposes holds ordinary shares or ADSs, the U.S. federal income tax treatment of a partner in the partnership will generally depend on the status of the partner and the activities of the partnership. Partnerships holding ordinary shares or ADSs and partners in such partnerships are encouraged to consult their tax advisors as to the particular U.S. federal income tax consequences of holding and disposing of our ordinary shares or ADSs.
This discussion is based on the Code, administrative pronouncements, judicial decisions, final, temporary and proposed Treasury Regulations and the income tax treaty between the United Kingdom and the United States (the “Treaty”), all as of the date hereof. These authorities are subject to change and differing interpretations, possibly retroactively, and may affect the tax consequences described herein.
For purposes of this discussion, a “U.S. Holder” is a holder that, for U.S. federal income tax purposes, is a beneficial owner of our ordinary shares or ADSs, is eligible for the benefits of the Treaty and is:
(a)a citizen or individual of the United States;
(b)a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organised in or under the laws of the United States, any state therein or the District of Columbia;
(c)an estate the income of which is subject to U.S. federal income taxation regardless of its source; or
(d)a trust if (i) a U.S. court is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have authority to control all substantial decisions of the trust or (ii) the trust has a valid election to be treated as a U.S. person under applicable U.S. Treasury Regulations.
U.S. Holders are encouraged to consult their tax advisors concerning the U.S. federal, state, local and non-U.S. tax consequences of owning and disposing of our ordinary shares or ADSs in their particular circumstances.
The discussion below assumes that the representations contained in the deposit agreement are true and that the obligations in the deposit agreement and any related agreement will be complied with in accordance with their terms. Generally, a holder of an ADS should be treated for U.S. federal income tax purposes as holding the ordinary shares represented by the ADS. Accordingly, no gain or loss will be recognised upon an exchange of ADSs for ordinary shares.

Passive Foreign Investment Company Rules
Generally, we will be a PFIC for U.S. federal income tax purposes for any taxable year in which either (1) 75% or more of our gross income consists of passive income or (2) 50% or more of the average quarterly value of our assets consists of assets that produce, or are held for the production of, passive income (including cash and cash equivalents). For purposes of these tests, passive income generally includes, among other things, dividends, interest, gains from certain sales or exchanges of investment property and certain rents and royalties. Further, we will be treated as owning our proportionate share of the assets and earning our proportionate share of the income of any other corporation, the equity of which we own, directly or indirectly, 25% or more (by value). If we are a PFIC for any taxable year during which a U.S. investor holds our shares, we will generally continue to be treated as a PFIC with respect to such U.S. investor for all succeeding taxable years during which such U.S. investor holds our shares, even if we cease to meet the threshold requirements for PFIC status. Such U.S. investor may be subject to adverse tax consequences, including ineligibility for any preferential tax rates on capital gains or on actual or deemed dividends, interest charges on certain taxes treated as deferred and additional reporting requirements. We cannot provide any assurance that we will furnish to such U.S. investor information that may be necessary to comply with the reporting and tax paying obligations applicable under the PFIC rules. U.S. Holders should consult their tax advisors regarding the potential application of the PFIC rules to their investment in our ordinary shares or ADSs.
Based upon the value of our assets and the nature and composition of our income and assets, we expect that we will not be a PFIC for the taxable year ended December 31, 2023, though no assurance can be made in this regard. The determination of whether we are a PFIC is a fact-intensive determination made on an annual basis applying principles and methodologies that in some circumstances are unclear and subject to varying interpretation. For instance, for our current and future taxable years, the total value of our assets (including goodwill) for PFIC testing purposes may be determined in part by reference to the market price of our ordinary shares or ADSs from time to time, which may fluctuate considerably. If our market capitalisation declines while we hold a substantial amount of cash and cash equivalents for any taxable year, we may be a PFIC for that taxable year. Furthermore, under the income test, our status as a PFIC depends on the composition of our income for the relevant taxable year, which will depend on the transactions we enter into in the future and our corporate structure. The composition of our income and assets is also affected by how we spend the cash we raise in any offering. We currently do not generate revenues from the commercialisation of drug candidates and therefore we may be a PFIC for any taxable year in which we do not generate sufficient amounts of active income to offset our passive financing income. As a result, there can be no assurance that we will not be a PFIC for the current or any future taxable year and our U.S. counsel expresses no opinion with respect to our PFIC status for any prior, current or future taxable year. Even if we determine that we are not a PFIC for a taxable year, there can be no assurance that the IRS will agree with our conclusion and that the IRS would not successfully challenge our position.
If we are a PFIC in any taxable year with respect to which a U.S. Holder owns our ordinary shares or ADSs, we will continue to be treated as a PFIC with respect to such U.S. Holder in all succeeding years during which such U.S. Holder owns our ordinary shares or ADSs, regardless of whether we continue to meet the tests described above, unless we cease to be a PFIC and such U.S. Holder has made a “deemed sale” election under the PFIC rules. If such a deemed sale election is made, a U.S. Holder will be deemed to have sold our ordinary shares or ADSs the U.S. Holder holds at their fair market value and any gain from such deemed sale would be subject to the rules described below. After the deemed sale election, so long as we do not become a PFIC in a subsequent taxable year, the U.S. Holder’s ordinary shares or ADSs with respect to which such election was made will not be treated as shares in a PFIC and the U.S. Holder will not be subject to the rules described below with respect to any “excess distribution” the U.S. Holder receives from us or any gain from an actual sale or other disposition of our ordinary shares or
191

Table of Contents
ADSs. U.S. Holders should consult their tax advisors as to the possibility and consequences of making a deemed sale election if we are a PFIC and cease to be a PFIC and such election becomes available.
For each taxable year that we are treated as a PFIC with respect to a U.S. Holder, such U.S. Holder will be subject to special tax rules with respect to any “excess distribution” such U.S. Holder receives and any gain such U.S. Holder recognizes from a sale or other disposition (including a pledge) of our ordinary shares or ADSs, unless (i) such U.S. Holder makes a “qualified electing fund” election, or QEF Election (as discussed below), with respect to all taxable years during such U.S. Holder’s holding period in which we are a PFIC or (ii) our ordinary shares or ADSs constitute “marketable stock” and such U.S. Holder makes a mark-to-market election (as discussed below). Distributions such U.S. Holder receives in a taxable year that are greater than 125% of the average annual distributions such U.S. Holder received during the shorter of the three preceding taxable years or the U.S. Holder’s holding period for our ordinary shares or ADSs will be treated as an excess distribution. Under these special tax rules:
the excess distribution or gain will be allocated ratably over a U.S. Holder’s holding period for the ordinary shares or ADSs;
the amount allocated to the current taxable year, and any taxable year prior to the first taxable year in which we became a PFIC, will be treated as ordinary income; and
the amount allocated to each other year will be subject to the highest tax rate in effect for that year and the interest charge generally applicable to underpayments of tax will be imposed on the resulting tax attributable to each such year.
The tax liability for amounts allocated to taxable years prior to the taxable year of disposition or “excess distribution” cannot be offset by any net operating losses for such years, and gains (but not losses) realised on the sale of the ordinary shares or ADSs cannot be treated as capital gains, even if the U.S. Holder holds the ordinary shares or ADSs as capital assets.
If we are a PFIC in any taxable year with respect to which a U.S. Holder owns our ordinary shares or ADSs, such U.S. Holder will generally be subject to similar rules with respect to distributions we receive from, and our dispositions of the stock of, any of our direct or indirect subsidiaries or any other entities in which we hold equity interests that also are PFICs, or lower-tier PFICs, as if such distributions were indirectly received by, and/or dispositions were indirectly carried out by, such U.S. Holder. U.S. Holders should consult their tax advisors regarding the application of the PFIC rules to lower-tier PFICs.
We do not currently expect to provide information that would allow a U.S. Holder to make a QEF election if we or any of our subsidiaries are a PFIC and, therefore, U.S. Holders should assume such election will not be available if we or any of our subsidiaries are a PFIC.
If we are a PFIC in any taxable year with respect to which a U.S. Holder owns our ordinary shares or ADSs, such U.S. Holder can avoid the interest charge on excess distributions or gain relating to the ordinary shares or ADSs by making a mark-to-market election with respect to the ordinary shares or ADSs, provided that the ordinary shares or ADSs are “marketable stock.” Ordinary shares or ADSs will be marketable stock if they are “regularly traded” on certain U.S. stock exchanges or on a non-U.S. stock exchange that meets certain conditions. For these purposes, the ordinary shares or ADSs will be considered regularly traded during any calendar year during which they are traded, other than in de minimis quantities, on at least 15 days during each calendar quarter. Any trades that have as their principal purpose meeting this requirement will be disregarded. Our ADSs (but not ordinary shares) will be listed on the Nasdaq, which is a qualified exchange for these purposes. Consequently, if our ADSs remain listed on the Nasdaq and are regularly traded, we expect the mark-to-market election would be available to U.S. Holders of our ADSs if we are a PFIC. Each U.S. Holder should consult its tax advisor as to whether a mark-to-market election is available or advisable with respect to our ordinary shares or ADSs.
192

Table of Contents
A U.S. Holder that makes a mark-to-market election must include in ordinary income for each year an amount equal to the excess, if any, of the fair market value of the ordinary shares or ADSs at the close of the taxable year over the U.S. Holder’s adjusted tax basis in the ordinary shares or ADSs. An electing U.S. Holder may also claim an ordinary loss deduction for the excess, if any, of the U.S. Holder’s adjusted tax basis in the ordinary shares or ADSs over the fair market value of the ordinary shares or ADSs at the close of the taxable year, but this deduction is allowable only to the extent of any net mark-to-market gains for prior years. Gains from an actual sale or other disposition of the ordinary shares or ADSs will be treated as ordinary income, and any losses incurred on a sale or other disposition of the ordinary shares or ADSs will be treated as an ordinary loss to the extent of any net mark-to-market gains for prior years. Once made, the election cannot be revoked without the consent of the IRS unless the ordinary shares or ADSs cease to be marketable stock.
However, a mark-to-market election generally cannot be made for equity interests in any lower-tier PFICs that we own, unless shares of such lower-tier PFICs are themselves “marketable stock.” As a result, even if a U.S. Holder validly makes a mark-to-market election with respect to our ordinary shares or ADSs, the U.S. Holder may continue to be subject to the PFIC rules (described above) with respect to its indirect interest in any of our investments that are treated as an equity interest in a PFIC for U.S. federal income tax purposes. U.S. Holders should consult their tax advisors as to the availability and desirability of a mark-to-market election, as well as the impact of such election on interests in any lower-tier PFICs.
Unless otherwise provided by the U.S. Treasury, each U.S. shareholder of a PFIC is required to file an annual report containing such information as the U.S. Treasury may require. A U.S. Holder’s failure to file the annual report may result in substantial penalties and extend the statute of limitations with respect to the U.S. Holder’s U.S. federal income tax return. U.S. Holders should consult their tax advisors regarding the requirements of filing such information returns under the PFIC rules.
WE STRONGLY URGE U.S. HOLDERS TO CONSULT THEIR TAX ADVISORS REGARDING THE IMPACT OF OUR PFIC STATUS AS WELL AS THE PFIC RULES ON THEIR INVESTMENT IN OUR ORDINARY SHARES OR ADSs.

Taxation of Distributions
Subject to the discussion above under “Passive Foreign Investment Company Rules,” distributions paid on our ordinary shares or ADSs, other than certain pro rata distributions of our ordinary shares or ADSs, will generally be treated as dividends to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Because we may not calculate our earnings and profits under U.S. federal income tax principles, we expect that distributions generally will be reported to U.S. Holders as dividends. Subject to applicable limitations, dividends paid to certain non-corporate U.S. Holders may be taxable at preferential rates applicable to “qualified dividend income” received from a “qualified foreign corporation.” A non-U.S. corporation generally will be considered a qualified foreign corporation (i) if it is eligible for the benefits of a comprehensive tax treaty with the United States which the Secretary of Treasury of the United States determines is satisfactory for purposes of these rules and which includes an exchange of information provision (which includes the Treaty) or (ii) with respect to any dividend it pays on ordinary shares or ADSs which are readily tradable on an established securities market in the United States. However, the qualified dividend income treatment will not apply if we are treated as a PFIC with respect to the U.S. Holder for our taxable year of the distribution or the preceding taxable year. The amount of the dividend will be treated as foreign-source dividend income to U.S. Holders and will not be eligible for the dividends-received deduction generally available to U.S. corporations under the Code. Dividends will generally be included in a U.S. Holder’s
193

Table of Contents
income on the date of the U.S. Holder’s actual or constructive receipt of the dividend. The amount of any dividend income paid in foreign currency will be the U.S. dollar amount calculated by reference to the exchange rate in effect on the date of actual or constructive receipt, regardless of whether the payment is in fact converted into U.S. dollars. If the dividend is converted into U.S. dollars on the date of receipt, a U.S. Holder should not be required to recognize foreign currency gain or loss in respect of the dividend income. A U.S. Holder may have foreign currency gain or loss if the dividend is converted into U.S. dollars after the date of receipt. Such gain or loss would generally be treated as U.S.-source ordinary income or loss. The amount of any distribution of property other than cash (and other than certain pro rata distributions of ordinary shares or ADSs or rights to acquire ordinary shares or ADSs) will be the fair market value of such property on the date of distribution. For foreign tax credit purposes, our dividends will generally be treated as passive category income.

Sale or Other Taxable Disposition of Ordinary Shares and ADSs
Subject to the discussion above under “Passive Foreign Investment Company Rules,” gain or loss realised on the sale or other disposition of our ordinary shares or ADSs will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder held the ordinary shares or ADSs for more than one year. The amount of the gain or loss will equal the difference between the U.S. Holder’s tax basis in the ordinary shares or ADSs disposed of and the amount realised on the disposition, in each case as determined in U.S. dollars. This gain or loss will generally be U.S.-source gain or loss for foreign tax credit purposes. The deductibility of capital losses is subject to limitations.
If the consideration received by a U.S. Holder is not paid in U.S. dollars, the amount realised will be the U.S. dollar value of the payment received determined by reference to the spot rate of exchange on the date of the sale or other disposition. However, if the ordinary shares or ADSs are treated as traded on an “established securities market” and the U.S. Holder is either a cash basis taxpayer or an accrual basis taxpayer that has made a special election (which must be applied consistently from year to year and cannot be changed without the consent of the IRS), the U.S. Holder will determine the U.S. dollar value of the amount realised in a non-U.S. dollar currency by translating the amount received at the spot rate of exchange on the settlement date of the sale. If the U.S. Holder is an accrual basis taxpayer that is not eligible to or does not elect to determine the amount realised using the spot rate on the settlement date, the U.S. Holder will recognize foreign currency gain or loss to the extent of any difference between the U.S. dollar amount realised on the date of sale or other disposition and the U.S. dollar value of the currency received at the spot rate on the settlement date.

Information Reporting and Backup Withholding
Payments of dividends and sales proceeds that are made within the United States or through certain U.S.-related financial intermediaries generally are subject to information reporting, and may be subject to backup withholding, unless (i) the U.S. Holder is a corporation or other exempt recipient or (ii) in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding.
Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the holder’s U.S. federal income tax liability and may entitle it to a refund, provided that the required information is timely furnished to the IRS. If any amount is withheld under the backup withholding rules, U.S. Holders are urged to consult their tax advisors regarding the possibility of and procedure for obtaining a refund or a credit against their U.S. federal income tax liability, if any.

Information With Respect to Foreign Financial Assets
Certain U.S. Holders who are individuals (and, under proposed regulations, certain entities) may be required to report information relating to our ordinary shares or ADSs, subject to certain exceptions (including an exception for ordinary shares or ADSs held in accounts maintained by certain U.S. financial institutions). U.S. Holders should consult their tax advisors regarding their reporting obligations with respect to their ownership and disposition of our ordinary shares or ADSs.

United Kingdom Taxation
The following is intended as a general guide to current U.K. tax law and HM Revenue & Customs, or HMRC, published practice applying as at the date of this annual report (both of which are subject to change at any time, possibly with retrospective effect) relating to the holding of ADSs. It does not constitute legal or tax advice and does not purport to be a complete analysis of all U.K. tax considerations relating to the holding of ADSs, or all of the circumstances in which holders of ADSs may benefit from an exemption or relief from U.K. taxation. It is written on the basis that the company does not (and will not) directly or indirectly derive 75% or more of its qualifying asset value from U.K. land, and that the company is and remains solely resident in the United Kingdom for tax purposes and will therefore be subject to the U.K. tax regime and not the U.S. tax regime save as set out above under “Material U.S. federal income tax considerations for U.S. Holders.”
Except to the extent that the position of non-U.K. resident persons is expressly referred to, this guide relates only to persons who are resident (and, in the case of individuals, domiciled or deemed domiciled and to whom split year treatment does not apply) for tax purposes solely in the United Kingdom and do not have a permanent establishment, branch, agency (or equivalent) or fixed base in any other jurisdiction with which the holding of the ADSs is connected, or U.K. Holders, who are absolute beneficial owners of the ADSs (where the ADSs are not held through an Individual Savings Account or a Self-Invested Personal Pension) and who hold the ADSs as investments.
This guide may not relate to certain classes of U.K. Holders, such as (but not limited to):
persons who are connected with the company;
financial institutions;
insurance companies;
charities or tax-exempt organisations;
collective investment schemes;
pension schemes;
market makers, intermediaries, brokers or dealers in securities;
persons who have (or are deemed to have) acquired their ADSs by virtue of an office or employment or who are or have been officers or employees of the company or any of its affiliates; and
individuals who are subject to U.K. taxation on a remittance basis.
The decision of the First-tier Tribunal (Tax Chamber) in HSBC Holdings PLC and The Bank of New York Mellon Corporation v HMRC (2012) cast some doubt on whether a holder of a depositary receipt is the beneficial owner of the underlying shares. However, based on published HMRC guidance we would expect that HMRC will regard a holder of ADSs as holding the beneficial interest in the underlying shares and therefore these paragraphs assume that a holder of ADSs is the beneficial owner of the underlying ordinary shares and any dividends paid in respect of the underlying ordinary shares (where the dividends are regarded for U.K. purposes as that person’s own income) for U.K. direct tax purposes.
195

Table of Contents
THESE PARAGRAPHS ARE A SUMMARY OF CERTAIN U.K. TAX CONSIDERATIONS AND ARE INTENDED AS A GENERAL GUIDE ONLY. IT IS RECOMMENDED THAT ALL HOLDERS OF ADSs OBTAIN ADVICE AS TO THE CONSEQUENCES OF THE ACQUISITION, OWNERSHIP AND DISPOSAL OF THE ADSs IN THEIR OWN SPECIFIC CIRCUMSTANCES FROM THEIR OWN TAX ADVISORS. IN PARTICULAR, NON-U.K. RESIDENT OR DOMICILED PERSONS ARE ADVISED TO CONSIDER THE POTENTIAL IMPACT OF ANY RELEVANT DOUBLE TAXATION AGREEMENTS.

United Kingdom Taxation of Dividends
Withholding Tax. Dividends paid by the company will not be subject to any withholding or deduction for or on account of U.K. tax.
Income Tax. An individual U.K. Holder may, depending on his or her particular circumstances, be subject to U.K. tax on dividends received from the company. An individual holder of ADSs who is not resident for tax purposes in the United Kingdom should not be chargeable to U.K. income tax on dividends received from the company unless he or she carries on (whether solely or in partnership) a trade, profession or vocation in the United Kingdom through a branch or agency to which the ADSs are attributable. There are certain exceptions for trading in the United Kingdom through independent agents, such as some brokers and investment managers.
All dividends received by an individual U.K. Holder from us or from other sources will form part of that U.K. Holder’s total income for income tax purposes and will constitute the top slice of that income. A nil rate of income tax will apply to the first £1,000 of taxable dividend income received by the individual U.K. Holder in the tax year 2023/2024. Income within the nil rate band is to be taken into account in determining whether income in excess of the £1,000 tax-free allowance falls within the basic rate, higher rate or additional rate tax bands. Dividend income in excess of the tax-free allowance is (subject to the availability of any income tax personal allowance) taxed at 8.75% to the extent that the excess amount falls within the basic rate tax band, 33.75% to the extent that the excess amount falls within the higher rate tax band and 39.35% to the extent that the excess amount falls within the additional rate tax band. The annual tax-free dividend allowance has been reduced to £1,000 with effect from April 2023, and will be reduced to £500 with effect from April 2024.
Corporation Tax. A corporate holder of ADSs that is not resident for tax purposes in the United Kingdom should not be chargeable to U.K. corporation tax on dividends received from the company unless it carries on (whether solely or in partnership) a trade in the United Kingdom through a permanent establishment to which the ADSs are attributable.
Corporate U.K. Holders should not be subject to U.K. corporation tax on any dividend received from the company so long as the dividend qualifies for an exemption, which should be the case, although certain conditions must be met. If the conditions for the exemption are not satisfied, or such U.K. Holder elects for an otherwise exempt dividend to be taxable, U.K. corporation tax will be chargeable on the amount of any dividends (at the main rate of 25% for companies with profits in excess of £250,000, or the small profits rate of 19% for companies with profits of £50,000 or less, with marginal relief from the main rate available to companies with profits between £50,000 and £250,000 subject to meeting certain criteria).

196

Table of Contents
Chargeable Gains. A disposal or deemed disposal of ADSs by a U.K. Holder may, depending on the U.K. Holder’s circumstances and subject to any available exemptions or reliefs (such as the annual exemption), give rise to a chargeable gain or an allowable loss for the purposes of U.K. capital gains tax and corporation tax on chargeable gains.
If an individual U.K. Holder who is subject to U.K. income tax at either the higher or the additional rate is liable to U.K. capital gains tax on the disposal of ADSs, the current applicable rate will be 20%. For an individual U.K. Holder who is subject to U.K. income tax at the basic rate and liable to U.K. capital gains tax on such disposal, the current applicable rate would be 10%, save to the extent that any capital gains when aggregated with the U.K. Holder’s other taxable income and gains in the relevant tax year exceed the unused basic rate tax band. In that case, the rate currently applicable to the excess would be 20%.
If a corporate U.K. Holder becomes liable to U.K. corporation tax on the disposal (or deemed disposal) of ADSs, U.K. corporation tax would apply (at the main rate of 25% for companies with profits in excess of £250,000, or the small profits rate of 19% for companies with profits of £50,000 or less, with marginal relief from the main rate available to companies with profits between £50,000 and £250,000 subject to meeting certain criteria).
A holder of ADSs which is not resident for tax purposes in the United Kingdom should not normally be liable to U.K. capital gains tax or corporation tax on chargeable gains on a disposal (or deemed disposal) of ADSs unless the person is carrying on (whether solely or in partnership) a trade, profession or vocation in the United Kingdom through a branch or agency (or, in the case of a corporate holder of ADSs, through a permanent establishment) to which the ADSs are attributable. However, an individual holder of ADSs who has ceased to be resident for tax purposes in the United Kingdom for a period of less than five years and who disposes of ADSs during that period may be liable on his or her return to the United Kingdom to U.K. tax on any capital gain realised (subject to any available exemption or relief).
United Kingdom Stamp Duty and Stamp Duty Reserve Tax. The discussion below relates to the holders of our ordinary shares or ADSs wherever resident, however it should be noted that special rules may apply to certain persons such as market makers, brokers, dealers or intermediaries. It should also be noted that this discussion assumes that the Finance Bill currently proceeding through the U.K. Parliament is enacted in its current form, and that measures taken to give certain Finance Bill provisions effect on a provisional basis continue to apply until such enactment.
Issue of Ordinary Shares. No U.K. stamp duty or stamp duty reserve tax, or SDRT, is payable on the issue of the underlying ordinary shares in the company.
Transfers of Ordinary Shares. An unconditional agreement to transfer ordinary shares in certificated form will normally give rise to a charge to SDRT at the rate of 0.5% of the amount or value of the consideration payable for the transfer. The purchaser of the shares is liable for the SDRT. Transfers of ordinary shares in certificated form are generally also subject to stamp duty at the rate of 0.5% of the amount or value of the consideration given for the transfer (rounded up to the next £5.00). Stamp duty is normally paid by the purchaser. The charge to SDRT will be canceled or, if already paid, repaid (generally with interest), where a transfer instrument has been duly stamped within six years of the charge arising (either by paying the stamp duty or by claiming an appropriate relief) or if the instrument is otherwise exempt from stamp duty.
An unconditional agreement to transfer ordinary shares to, or to a nominee or agent for, a person whose business is or includes the issue of depositary receipts or the provision of clearance services will generally be subject to SDRT (or, where the transfer is effected by a written instrument, stamp duty) at a higher rate of 1.5% of the amount or value of the consideration given for the transfer unless the clearance service has made and maintained an election under section 97A of the U.K. Finance Act 1986, or a section 97A

election. It is understood that HMRC regards the facilities of DTC as a clearance service for these purposes and we are not aware of any section 97A election having been made by DTC. However, no stamp duty or SDRT is payable where the transfer of ordinary shares to a clearance service or depositary receipt system satisfies the conditions of an exemption, which will generally be the case if the transfer occurs in the course of qualifying capital-raising arrangements.
Any stamp duty or SDRT payable on a transfer of ordinary shares to a depositary receipt system or clearance service will in practice generally be paid by the transferors or participants in the clearance service or depositary receipt system.
Issue of ADSs. No U.K. stamp duty or SDRT is payable on the issue of ADSs in the company.
Transfers of ADSs. No SDRT should be required to be paid on a paperless transfer of ADSs through the clearance service facilities of DTC, provided that no section 97A election has been made by DTC, and such ADSs are held through DTC at the time of any agreement for their transfer.
No U.K. stamp duty will in practice be payable on a written instrument transferring an ADS provided that the instrument of transfer is executed and remains at all times outside the United Kingdom. Where these conditions are not met, the transfer of, or agreement to transfer, an ADS could, depending on the circumstances, attract a charge to U.K. stamp duty at the rate of 0.5% of the amount or value of the consideration. If it is necessary to pay stamp duty, it may also be necessary to pay interest and penalties.

Item 11. Quantitative and Qualitative Disclosures About Market Risk
We are exposed to interest rate, currency, credit and liquidity risks. Our executive board oversees the management of these risks.
Interest Rate Risk. Our exposure to the risk of changes in interest rates relates to investments in deposits. Changes in the general level of interest rates may lead to an increase or decrease in the fair value of these investments. Calculated using our cash and cash equivalents at December 31, 2023, a hypothetical 1% change in interest rates with all other variables held constant would lead to an increase or decrease in profit and equity of £1.0 million.
Regarding the liabilities shown in the statement of financial position, we are currently not subject to interest rate risks.
Currency Risk. Foreign currency risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in foreign exchange rates. Our exposure to the risk of changes in foreign exchange relates primarily to cash and cash equivalents and outsourced supplier agreements denominated in currencies other than pounds sterling, in addition to our operations based in the United States and Japan.
Our cash, cash equivalents and short term bank deposits were £363.0 million and £505.8 million as of December 31, 2023 and 2022 respectively. As of December 31, 2023, approximately all of our cash and cash equivalents were held in the United Kingdom, of which 78% were denominated in pounds sterling, 21% were dominated in U.S. dollars and 1% were denominated in Euro. Correspondingly, as of December 31, 2022, these were 85%, 13% and 2%, respectively.
A hypothetical 10% change in the GBP/USD and GBP/EUR exchange rates during the year ended December 31, 2023 would have had a £9.0 million and £0.0 million impact, respectively, on our consolidated loss before tax and would have had a £9.1 million and £3.6 million impact, respectively, on shareholders equity. For all other currencies, a hypothetical change of 10% in exchange rates during any of the periods presented would not have had a material impact on our consolidated financial statements.
A hypothetical 10% change in the GBP/USD and GBP/EUR exchange rates during the year ended December 31, 2022 would have had a £6.3 million and £0.2 million impact, respectively, on our consolidated loss before tax and would have had a £6.1 million and £4.6 million impact, respectively, on shareholders equity. For all other currencies, a hypothetical change of 10% in exchange rates during any of the periods presented would not have had a material impact on our consolidated financial statements.
We hold cash and short term bank deposits in both GBP and USD, with the intention of matching expected operational cash needs in order to limit the impact of exchange rate fluctuations on our operations.
Credit Risk. We are exposed to credit risk from our operating activities, primarily trade receivables, and cash, cash equivalents and deposits held with banks and financial institutions. Our cash, cash equivalents and deposits are maintained in accounts at five different banks and financial institutions in the United Kingdom, the United States of America, Austria and Japan. We are also potentially subject to concentrations of credit risk for our trade receivables with respect to receivables owed by a limited number of companies comprising our customer base. Our exposure to credit losses is low, however, due to the credit quality of our collaboration partners which are typically large pharmaceutical companies.
Liquidity Risk. We continuously monitor our risk of a shortage of funds. Our objective is to maintain a balance between continuity of funding and flexibility through the use of capital increases and executing collaboration agreements. Our financial statements were prepared on a going concern basis.

D. American Depositary Shares
Citibank N.A., or Citibank, acts as the depositary for the ADSs representing our ordinary shares. Citibank’s depositary offices are located at 388 Greenwich Street, New York, New York 10013. ADSs represent ownership interests in securities that are on deposit with the depositary. ADSs may be represented by certificates that are commonly known as American Depositary Receipts, or ADRs. The depositary typically appoints a custodian to safekeep the securities on deposit. In this case, the custodian is Citibank, N.A. (London), located at Citigroup Centre, Canary Wharf, London, E14 5LB, United Kingdom.
We have appointed Citibank as depositary pursuant to a deposit agreement. The form of the deposit agreement is on file with the SEC under cover of a registration statement on Form F-6. You may obtain a copy of the deposit agreement from the SEC’s website (www.sec.gov). Please refer to registration number 333- 259724 when retrieving such copy.
Fees and Charges. Holders of our ADSs will be required to pay the following fees under the terms of the deposit agreement:
ServiceFee
Issuance of ADSs (e.g., an issuance of ADS(s) upon a deposit of ordinary shares or upon a change in the ADS(s)-to-ordinary shares ratio, or for any other reason), excluding ADS issuances as a result of distributions of ordinary sharesUp to $0.05 per ADS issued
Cancellation of ADSs (e.g., a cancellation of ADSs for delivery of deposited property or upon a change in the ADS(s)-to-ordinary shares ratio, or for any other reason)Up to $0.05 per ADS cancelled
Distribution of cash dividends or other cash distributions (e.g., upon a sale of rights and other entitlements)Up to $0.05 per ADS held
Distribution of ADSs pursuant to (i) share dividends or other distributions, or (ii) exercise of rights to purchase additional ADSsUp to $0.05 per ADS held
Distribution of securities other than ADSs or rights to purchase additional ADSs (e.g., upon a spin-off)Up to $0.05 per ADS held
ADS servicesUp to $0.05 per ADS held on the applicable record date(s) established by the depositary
Registration of ADS transfers (e.g., upon a registration of the transfer of registered ownership of ADSs, upon a transfer of ADSs into DTC and vice versa, or for any other reason)Up to $0.05 per ADS transferred
Conversion of ADSs of one series for ADSs of another series (e.g., upon conversion of partial entitlement ADSs for full entitlement ADSs, or upon conversion of restricted ADSs into freely transferable ADSs, and vice versa)Up to $0.05 per ADS converted
201

Table of Contents
Holders of our ADSs will also be responsible to pay certain charges such as:
taxes (including applicable interest and penalties) and other governmental charges;
the registration fees as may from time to time be in effect for the registration of ordinary shares on the share register and applicable to transfers of ordinary shares to or from the name of the custodian, the depositary or any nominees upon the making of deposits and withdrawals, respectively;
certain cable, telex and facsimile transmission and delivery expenses;
the fees, expenses, spreads, taxes and other charges of the depositary bank and/or service providers (which may be a division, branch or affiliate of the depositary bank) in the conversion of foreign currency;
the reasonable and customary out-of-pocket expenses incurred by the depositary bank in connection with compliance with exchange control regulations and other regulatory requirements applicable to ordinary shares, ADSs and ADRs; and
the fees, charges, costs and expenses incurred by the depositary bank, the custodian, or any nominee in connection with the ADR program.
ADS fees and charges payable upon (i) the issuance of ADSs, and (ii) the cancellation of ADSs are charged to the person to whom the ADSs are issued (in the case of ADS issuances) and to the person whose ADSs are cancelled (in the case of ADS cancellations). In the case of ADSs issued by the depositary into DTC, the ADS issuance and cancellation fees and charges may be deducted from distributions made through DTC, and may be charged to the DTC participant(s) receiving the ADSs being issued or the DTC participant(s) holding the ADSs being cancelled, as the case may be, on behalf of the beneficial owner(s) and will be charged by the DTC participant(s) to the account of the applicable beneficial owner(s) in accordance with the procedures and practices of the DTC participants as in effect at the time. ADS fees and charges in respect of distributions and the ADS service fee are charged to the holders as of the applicable ADS record date. In the case of distributions of cash, the amount of the applicable ADS fees and charges is deducted from the funds being distributed. In the case of (i) distributions other than cash and (ii) the ADS service fee, holders as of the ADS record date will be invoiced for the amount of the ADS fees and charges and such ADS fees and charges may be deducted from distributions made to holders of ADSs. For ADSs held through DTC, the ADS fees and charges for distributions other than cash and the ADS service fee may be deducted from distributions made through DTC, and may be charged to the DTC participants in accordance with the procedures and practices prescribed by DTC and the DTC participants in turn charge the amount of such ADS fees and charges to the beneficial owners for whom they hold ADSs. In the case of (i) registration of ADS transfers, the ADS transfer fee will be payable by the ADS holder whose ADSs are being transferred or by the person to whom the ADSs are transferred, and (ii) conversion of ADSs of one series for ADSs of another series, the ADS conversion fee will be payable by the Holder whose ADSs are converted or by the person to whom the converted ADSs are delivered.
In the event of refusal to pay the depositary fees or charges, the depositary may, under the terms of the deposit agreement, refuse the requested service until payment is received or may set off the amount of the depositary fees and charges from any distribution to be made to the ADS holder.

Note that the fees and charges holders may be required to pay may vary over time and may be changed by us and by the depositary. Holders will receive prior notice of such changes. The depositary may reimburse us for certain expenses incurred by us in respect of the ADSs, by making available a portion of the ADS fees charged in respect of the ADSs or otherwise, upon such terms and conditions as we and the depositary agree from time to time.

Item 15. Controls and Procedures
A. Disclosure Controls and Procedures
We maintain “disclosure controls and procedures,” as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarised and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is accumulated and communicated to management, including our chief executive officer (principal executive officer) and chief financial officer (principal financial officer), as appropriate, to allow timely decisions regarding required disclosure.
Our principal executive officer and principal financial officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) as of December 31, 2023, have concluded that, as of such date, our disclosure controls and procedures were not effective at the reasonable assurance level.

B. Management’s Annual Report on Internal Control Over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) of the Exchange Act. Internal control over financial reporting is a process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer and effected by our board of directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with IFRS Accounting Standards issued by the International Accounting Standards Board (“IASB”).
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatement. Also, projections of any evaluation of the effectiveness of internal control to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Our management, including the Interim Chief Executive Officer and Chief Financial Officer, has assessed the effectiveness of our internal control over financial reporting as of December 31, 2023 based on the criteria described in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and based on this assessment, our management has concluded that as of December 31, 2023, our internal controls over financial reporting were not effective to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with IFRS as issued by IASB.
For additional information on our material weaknesses and remediation efforts, see Item 5. Operating and Financial Results.

D. Changes in Internal Control Over Financial Reporting
As reported in our annual report on Form 20-F for the fiscal year ended December 31, 2022, our management identified material weaknesses in our control over financial reporting related to the lack of effective process and controls throughout the period and we did not implement and maintain effective information technology general controls for information systems that are significant to the preparation of our financial statements.
As part of our changes in internal control over financial reporting, as of the date of this annual report for the year ended December 31, 2023, we have implemented a remediation plan with respect to the material weaknesses, including the hiring of several experienced personnel in our financial reporting and internal controls teams, as well as engaging external advisors to assist us in addressing these material weaknesses. See "Item 5.E – Critical Material Accounting Policies and Significant Judgements and Estimates—Internal Control Over Financial Reporting" for additional information.
With the exception of the changes listed above, there were no other changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the year ended December 31, 2023 that materially affected or are reasonably likely to materially affect our internal control over financial reporting.

Item 16G. Corporate Governance
As a “foreign private issuer,” as defined by the SEC, although we are permitted to follow certain corporate governance practices of England and Wales, instead of those otherwise required under The Nasdaq Global Select Stock Market, or Nasdaq, for domestic issuers, we intend to follow the Nasdaq corporate governance rules applicable to foreign private issuers. While we expect to voluntarily follow most Nasdaq corporate governance rules, we may choose to take advantage of the following limited exemptions:
Exemption from filing quarterly reports on Form 10-Q containing unaudited financial and other specified information or current reports on Form 8-K upon the occurrence of specified significant events;
Exemption from Section 16 rules requiring insiders to file public reports of their securities ownership and trading activities and providing for liability for insiders who profit from trades in a short period of time;
Exemption from the Nasdaq rules applicable to domestic issuers requiring disclosure within four business days of any determination to grant a waiver of the code of business conduct and ethics to directors and officers;
Exemption from the requirement to obtain shareholder approval for certain issuances of securities, including shareholder approval of share option plans;
Exemption from the requirement that our audit committee have review and oversight responsibilities over all “related party transactions,” as defined in Item 7.B of Form 20-F;
Exemption from the requirement that our board have a compensation committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities; and
Exemption from the requirements that director nominees are selected, or recommended for selection by our board, either by (1) independent directors constituting a majority of our board’s independent directors in a vote in which only independent directors participate, or (2) a committee comprised solely of independent directors, and that a formal written charter or board resolution, as applicable, addressing the nominations process is adopted.

Furthermore, Nasdaq Rule 5615(a)(3) provides that a foreign private issuer, such as we, may rely on home country corporate governance practices in lieu of certain of the rules in the Nasdaq Rule 5600 Series and Rule 5250(d), provided that we nevertheless comply with Nasdaq’s Notification of Noncompliance requirement (Rule 5625), the Voting Rights requirement (Rule 5640) and that we
have an audit committee that satisfies Rule 5605(c)(3), consisting of committee members that meet
the independence requirements of Rule 5605(c)(2)(A)(ii). Although we are permitted to follow certain corporate governance rules that conform to U.K. requirements in lieu of many of the Nasdaq corporate governance rules, we intend to comply with the Nasdaq corporate governance rules applicable to foreign private issuers.
Accordingly, our shareholders will not have the same protections afforded to shareholders of companies that are subject to all of the corporate governance requirements of Nasdaq. We may utilize these exemptions for as long as we continue to qualify as a foreign private issuer.

Item 16K. Cybersecurity
Risk management and strategy
We have implemented and maintain various information security processes designed to identify, assess and manage material risks from cybersecurity threats to: our critical computer networks; third-party hosted services, communications systems, hardware and software; and our critical data, which includes intellectual property, confidential information that is proprietary, strategic or competitive in nature, trade secrets, data we may collect about trial participants in connection with clinical trials, sensitive third-party data, business plans, transactions, and financial information, referred to collectively as Information Systems and Data.
Our cybersecurity function comprises, in part, our Chief Information Officer, or CIO, our Head of Information Security and the overall information security function, as well as our legal department and risk management team, and it helps identify, assess and manage our cybersecurity threats and risks. Our cybersecurity function identifies and assesses risks from cybersecurity threats by monitoring and evaluating our threat environment using various methods including, for example, manual tools, internal or external audits, automated tools, subscribing to and analysing reports and services that identify cybersecurity threats and threat actors, threat assessments and scans for internal and external threats, cyber assessments of all third parties, external intelligence feeds, vulnerability assessments, third-party-conducted red/blue team testing and tabletop incident response exercises, a third-party Managed Security Operations Centre with dedicated expert security analysts, and coordination with law enforcement concerning threats.
Depending on the environment, we implement and maintain various technical, physical, and organizational measures and processes designed to manage and mitigate material risks from cybersecurity threats to our Information Systems and Data, including, for example: incident detection and response, a cyber incident response plan, a disaster recovery plan, a vendor risk management program, employee training, data encryption, access controls, physical security, network security controls, penetration testing, dedicated cybersecurity staff, a third-party Managed Security Operations Centre with dedicated expert security analysts, risk assessments, implementation of security standards/certifications, data segregation, systems monitoring, cyber insurance, and asset management, tracking, and disposal.
Our assessment and management of material risks from cybersecurity threats are integrated into our overall risk management processes. For example, the cybersecurity function works with our management to prioritize our risk management processes and mitigate cybersecurity threats that are more likely to lead to a material impact to our business.
We use third-party service providers to assist us from time to time to identify, assess, and manage material risks from cybersecurity threats, including for example professional services firms (including legal counsel), threat intel service providers, cybersecurity software providers, cybersecurity consultants, managed cybersecurity service providers, pen testing firms, dark web monitoring services, and forensic investigators. We also use third-party service providers to perform a variety of functions throughout our business, such as hosting companies, application providers, contract research organizations, supply chain resources, distributors, and contract manufacturing organizations. We manage cybersecurity risks associated with our use of these providers by, for example, conducting audits and risk assessments on certain vendors, conducting vulnerability scans relevant to the service provider, engaging in conversations with the service providers’ security personnel, imposing contractual obligations on the service providers, and requesting and analysing (a) responses on a security questionnaire, (b) the providers’ written information security program, and (c) relevant reports and certifications of the service providers.
216

Table of Contents
For a description of the risks from cybersecurity threats that may materially affect us and how they may do so, see "Item 3.D — Risk Factors," including the risk factor titled “Our internal information technology systems, or those of our third-party vendors, contractors or consultants, may fail or suffer security breaches, loss or leakage of data and other disruptions, which could result in adverse consequences resulting from any such incident, including but not limited to regulatory investigations or actions; litigation; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; loss of customers or sales; and other adverse consequences.”

Governance
Our board of directors addresses our cybersecurity risk management as part of its general oversight function. The Audit Committee is responsible for overseeing our cybersecurity risk management processes, including oversight and mitigation of risks from cybersecurity threats.
Our cybersecurity risk assessment and management processes are implemented and maintained by certain members of management, including our CIO, who has over 20 years of IT experience and our Head of Information Security, who has over 20 years of experience in the IT industry, 15 of which have been in cybersecurity.
Our CIO is responsible for approving budgets, helping prepare for cybersecurity incidents, approving cybersecurity processes, and reviewing security assessments and other security-related reports. Our Head of Information Security is responsible for hiring appropriate personnel, helping to integrate cybersecurity risk considerations into our overall risk management strategy, and communicating key priorities to relevant personnel.
Our response process to cybersecurity incidents is designed to escalate certain incidents to members of management depending on the circumstances, including the CIO. Our CIO and Head of Information Security work with the other members of our incident response team to help us mitigate and remediate cybersecurity incidents of which they are notified. In addition, our incident response policy includes reporting to the Audit Committee for certain cybersecurity incidents.
Our Audit Committee also receives periodic reports from our cybersecurity function concerning our significant cybersecurity threats and risk and the processes we have implemented to address them. The Audit Committee also has access to various reports, summaries or presentations related to cybersecurity threats, risk and mitigation.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Exscientia Plc

Opinion on the Financial Statements
We have audited the accompanying consolidated statement of financial position of Exscientia Plc and its subsidiaries (the “Company”) as of December 31, 2023 and 2022, and the related consolidated statements of loss and other comprehensive (loss)/income, of changes in equity and of cash flows for each of the three years in the period ended December 31, 2023, including the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023 in conformity with IFRS Accounting Standards as issued by the International Accounting Standards Board.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

2.Material Accounting Policies
a)     Statement of Compliance
The consolidated financial statements as of December 31, 2023 and 2022 and for the years ended December 31, 2023, 2022 and 2021 have been prepared in accordance with IFRS Accounting Standards issued by the International Accounting Standards Board (“IASB”).

The preparation of financial statements in compliance with IFRS requires the use of certain critical accounting estimates. It also requires management to exercise judgement in applying the Group's accounting policies (see note 3).

b)    Basis of Preparation
The accounting policies adopted in the preparation of these financial statements are set out below. These policies have been consistently applied to all the financial years presented, unless otherwise stated. The financial statements have been prepared on the historical cost basis, with the exception of certain financial instruments and assets and liabilities acquired in a business combination which are measured at fair value.
The financial statements have been presented in Pounds Sterling (“Sterling”). This is the functional currency of the Company, being the currency of the primary economic environment in which the Company operates, and the presentational currency of the group. All values are rounded to the nearest thousand pound ('£’000’) except where otherwise indicated.

These consolidated financial statements were authorised by the Board of Directors on March 14, 2024.

Table of Contents
Notes to the Financial Statements for the years ended 31 December, 2023, 2022 and 2021
c)    Basis of Consolidation
The Group financial statements consolidate the financial statements of Exscientia plc and all its subsidiary undertakings made up to December 31, 2023. Subsidiaries are those entities over which the Company exercises control. The group controls an entity where the group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power to direct the activities of the entity.

The results of subsidiaries acquired or sold are consolidated for the periods from or to the date on which control passed. Acquisitions are accounted for under the acquisition method with goodwill representing any excess of the fair value of the consideration given over the fair value of the identifiable assets and liabilities acquired.

d)    Going Concern
As at December 31, 2023, the Group’s cash, cash equivalents and short-term bank deposits amounted to £363,049,000 with total unrestricted cash and short term bank deposits amounting to £361,154,000. The Group has incurred significant research and development expenses from the start of the Group’s activities, with net cash outflows from operating activities amounted to £117,602,000 for the financial year ended December 31, 2023 (2022 £60,515,000).
Based upon the year-end cash, cash equivalents and short-term bank deposits and forecast future cashflows for the years ending 31 December 2024 and 2025 respectively, the Board of Directors believes that the Group has sufficient financial resources to cover its planned cash outflows for the foreseeable future, being a period of at least twelve months from the date of issuance of these financial statements.

As the Group has concluded that there is no substantial doubt about its ability to continue as a going concern within one year of the issuance of these financial statements, the Group has prepared these financial statements under the going concern assumption.
e)    Application of New and Revised IFRS Accounting Standards
In the year ended December 31, 2023, the Group has applied the below amendments to IFRS and interpretations issued by the Board that are effective for the annual period that begins on or after January 1, 2023.

Disclosure of Accounting Policies (Amendments to IAS 1 and IFRS Practice Statement 2)The amendments require that an entity discloses its material accounting policies, instead of its significant accounting policies. Further amendments explain how an entity can identify a material accounting policy.
Definition of Accounting Estimates (Amendments to IAS 8)The amendments replace the definition of a change in accounting estimates with a definition of accounting estimates. Under the new definition, accounting estimates are “monetary amounts in financial statements that are subject to measurement uncertainty”.
Deferred Tax related to Assets and Liabilities arising from a Single Transaction (Amendments to IAS 12)These amendments require companies to recognise deferred tax on transactions that, on initial recognition, give rise to equal amounts of taxable and deductible temporary differences.


F-11

Notes to the Financial Statements for the years ended 31 December, 2023, 2022 and 2021
The adoption of these new accounting pronouncements has not had a significant impact on the accounting policies, methods of computation or presentation applied by the Group except for the adoption of the amendments to IAS 12 Income Taxes. The amendment to IAS 12 Income Taxes was published in May 2021 and became effective for the Group from January 1, 2023. The amendment narrowed the scope of the deferred tax recognition exemption, so that it no longer applies to transactions that, on initial recognition, give rise to equal taxable and deductible temporary differences.
The Group has considered the impact of this amendment, most notably in relation to the accounting for deferred taxes on leases. There was no material impact to retained earnings as at both January 1, 2022 and December 31, 2022 as a result of transitioning to the revised standard. See note 23 for details of the impact on the Group's recognised deferred tax assets and liabilities as at December 31, 2022.

f)    Standards, Amendments and Interpretations in Issue But Not Yet Effective:
The adoption of the following mentioned standards, amendments and interpretations in future years are not expected to have a material impact on the Group’s financial statements:
Effective Date
Periods Beginning On or After
Amendment to IFRS 16 - Leases on sale and leaseback January 1, 2024
Classification of Liabilities as Current or Non-Current (Amendments to IAS 1)January 1, 2024

g)    Revenue from Contracts with Customers
The Group’s primary revenue is generated broadly from two streams that relate to its principal activities:
Licensing fees: We receive licensing fees from partnered programmes where we develop intellectual property on behalf of a collaboration partner. These agreements either assign all of the designated intellectual property to the partner from inception or grant an exclusive option to the partner to acquire rights to the future development and commercialisation of the intellectual property. As part of these agreements, we may receive future milestone and royalty payments upon achievement of clinical, regulatory and commercial milestones; and
Service fees: We generate service fees from drug discovery collaboration agreements where we are utilising our proprietary technology to develop novel intellectual property on behalf of the collaboration partner, but do not have any rights to future milestones and royalties as a direct result of the agreement. Until March 2023, we also generated service revenues through our Exscientia GmbH entity related to collaboration agreements that existed with Exscientia GmbH at the time of our acquisition.
The Group receives four types of payments included within the two streams of revenue:
“Upfront payments” are generally payable on execution of the collaboration agreement or on initiation of a project;
“Research funding” (including term extension payments), which is generally payable throughout the collaboration at defined intervals as set out in the agreement (e.g., quarterly or at the beginning of a specific phase of work) and is intended to fund research (internal and external) which is undertaken to develop the collaboration drug compound that is the subject of the collaboration;

F-12

Table of Contents
Notes to the Financial Statements for the years ended 31 December, 2023, 2022 and 2021
“Milestone payments” are linked to the achievement of an event, as defined in the collaboration agreement e.g. initiation of Phase 1 clinical trial milestones and constitute variable consideration in accordance with IFRS15; and
“Opt-in payments” are similar in principal to milestone payments, however, are payable when the partner exercises its option to take ownership of the designated intellectual property. These payments only exist where the Group initially retained ownership of the designed intellectual property.
Under these collaboration agreements the Group may also receive commercialisation milestones upon the first commercial sale of a product, if and when approved, the amount of which is based on the territory the sale occurs in, and royalties based on worldwide net sales. These amounts have not been included within the transaction price for any contract as of December 31, 2023, 2022 or 2021. We have only recognised revenue in respect of non-cancellable, non-refundable payments and achieved milestones due under executed collaboration contracts. Any payments which relate to future milestones or options under the control of our collaboration partners have not been recognised.
In accordance with IFRS 15, the Group recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the Group expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that the Group determines are within the scope of IFRS 15, the Group performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when or as the Group satisfies a performance obligation.

At contract inception, the Group assesses the goods or services promised within each contract that falls under the scope of IFRS 15 to identify distinct performance obligations. The Group then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when or as the performance obligation is satisfied. Revenue is measured at the contract price excluding value added tax and other sales taxes.

The Group includes the unconstrained amount of estimated variable consideration in the transaction price, such that only amounts for which it is highly probable that a significant reversal of cumulative revenue recognised will not occur are included. At contract inception, unconstrained revenue will typically include the upfront payments and in some instances, research funding.

At the inception of each arrangement that includes research, development, or regulatory milestone payments, the Group evaluates whether the milestones (i) relate to the one or more distinct performance obligations under the agreement; and (ii) are considered highly probable of being reached and estimate the amount to be included in the transaction price using the most likely amount method. If it is highly probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within our control or that of the licensee, such as regulatory approvals, are not considered highly probable of being achieved until those approvals are received.

At the end of each subsequent reporting period, the Group re-evaluates the estimated variable consideration included in the transaction price and any related constraint and, if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which may affect license, fees, and other revenues and earnings in the period of adjustment.

The transaction price is then allocated to each performance obligation on a relative stand-alone selling

price basis, for which the Group recognizes revenue as or when the performance obligations under the contract are satisfied.

When determining whether performance obligations have been satisfied, progress is measured using an input method utilising either total or external costs or labour hours incurred depending on the nature of the collaboration arrangement to establish and estimate the progress of completion. Management has determined the input method represents a faithful depiction of the Group’s progress towards completion of performance obligations because the time and costs incurred depict the progress of development of the underlying IP which may be transferred to the customer. At the end of each reporting period, the Group re-evaluates costs/hours incurred compared with total expected costs/hours to recognize revenue for each performance obligation. In certain instances expected total cost estimates include estimated costs relating to the substitution of targets where allowed in accordance with a specific collaboration agreement.
For obligations recognised over time the Group recognizes revenue only equal to a percentage of costs incurred until such time that it can reasonably estimate the total expected costs/hours to be incurred in delivering the performance obligation. For obligations in which revenue is recognised at a point in time, that point in time is the date at which the title of the service or IP is transferred to the customer.

Contract liabilities consists of billings or payments received in advance of revenue recognition. Contract assets consists of revenue recognised in advance of billings or payments.

h)    Grants
Grants compensating the Group for research activities undertaken and are recognised in profit or loss as other income on a systematic basis in the periods in which the expenses are recognised, unless the conditions for receiving the grant are met after the related expenses have been recognised. In this case, the grant is recognised when it becomes receivable.

i)    Foreign Currencies
At each period-end foreign currency monetary items are translated using the closing rate. Non-monetary items measured at historical cost are translated using the exchange rate at the date of the transaction and non-monetary items measured at fair value are measured using the exchange rate when fair value was determined.

Foreign exchange gains and losses resulting from the settlement of transactions and from the translation at period-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in profit or loss.

On consolidation, the results of overseas operations are translated into pounds sterling at rates approximating to those ruling when the transactions took place. All assets and liabilities of overseas operations are translated at the rate ruling at the reporting date, inclusive of goodwill and any intangible assets which are attributable to those operations. Exchange differences arising on translating overseas operations are recognised in other comprehensive income and accumulated in a separate reserve within equity. The cumulative amount is reclassified to profit or loss when the net investment is disposed of.

j)    Intangible Assets
Goodwill. Goodwill is recognised in a business combination when the consideration transferred by the acquirer exceeds the net identifiable assets acquired. Goodwill is not amortised but is reviewed for impairment at least annually.

I
ntangible assets other than goodwill. Intangible assets acquired separately are measured on initial recognition at cost. Following initial recognition, intangible assets are carried at cost less accumulated amortisation and accumulated impairment losses.
Intangible assets with finite lives are amortised over their useful economic lives from the point at which the intangible asset in question is brought into use, and assessed for impairment whenever there is an indication that the intangible asset may be impaired. Assets yet to be brought into use are assessed for impairment at least annually. The amortisation period and the amortisation method for an intangible asset with a finite useful life is reviewed at least at the end of each reporting period.
Changes in the expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset is accounted for by changing the amortisation period or method, as appropriate, and are treated as changes in accounting estimates. The amortisation expense on intangible assets with finite lives is recognised in profit or loss in the expense category consistent with the function of the intangible assets.

Computer Software
4 years on a straight line basis
PatentsOver the term of the patent on a straight line basis
Acquired IP
8 years from the acquisition date/date the asset is brought into use on a straight line basis


Amortisation of intangible assets is included under the ‘Research and development expenses’ and ‘General and administrative expenses’ classifications in the Statement of Loss and Other Comprehensive Loss based on the nature of the underlying expenditure.

k)    Cost of Sales
Costs of sales relates to costs from third-party contract research organisations as well as internal labour and absorbed overheads incurred in relation to collaboration arrangements and drug discovery agreements for third parties which have been designated as contracts with customers in accordance with IFRS 15.

l)    Property, Plant and Equipment
Assets under construction, plant and equipment, fixtures and fittings, computer equipment and leasehold improvements are initially recognised at acquisition cost, including any costs directly attributable to bringing the assets to the location and condition necessary for it to be capable of operating in the manner intended by the Group’s management. These assets are subsequently measured using the cost model, less accumulated depreciation and impairment losses. Depreciation is provided at rates calculated to write off the cost of assets, less their estimated residual value on a straight line basis, over their expected lives:

Assets Under ConstructionNot Depreciated
Plant and Equipment

Fixture and Fittings
5 years
Leasehold ImprovementsOver the term of the lease or to the first-break clause, whichever is earlier
Computer Equipment

m)    Cash and Cash Equivalents and Short Term Bank Deposits
Cash is cash on hand and demand deposits. Cash equivalents are short-term, highly liquid investments that are readily convertible to known amounts of cash and which are subject to insignificant risk of changes in value.
Short term bank deposits consist of bank deposits of 12 months duration or less, and are measured at amortised cost as described in section s) below.
n)    Impairment of Assets
Individual assets are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable with the exception of acquired IP yet to be brought into use, which is reviewed for impairment at least annually.

An asset is impaired when its carrying amount exceeds its recoverable amount. The recoverable amount is measured as the higher of fair value less cost of disposal and value in use. The value in use is calculated as being net projected cash flows based on financial forecasts discounted back to present value.

Recoverable amount is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets. If this is the case, recoverable amount is determined for the cash-generating unit to which the asset belongs. If it is deemed that an impairment is necessary the impairment loss is allocated to reduce the carrying amount of the asset, first against the carrying amount of any goodwill allocated to the cash-generating unit, and then to the other assets of the unit pro-rata on the basis of the carrying amount of each asset in the unit. With the exception of goodwill, all assets are subsequently reassessed for indications that an impairment loss previously recognised may no longer exist. An impairment loss is reversed if the asset’s or cash-generating unit’s recoverable amount exceeds its carrying amount.
o)    Joint Ventures and Joint Operations
Investments in joint ventures are accounted for using the equity method in the Group’s financial statements. Under the equity method, the investment is recognised initially at cost and the carrying amount of the investment is adjusted to recognize changes in the Group’s share of net assets.
Investments in joint ventures are tested for impairment annually, and an impairment loss is recognised where it is indicated that the carrying amount of the investment may not be recoverable. The recoverable amount is measured as the higher of fair value less cost of disposal and value in use. The value in use is calculated as being net projected cash flows based on financial forecasts discounted back to present value. The Group also undertakes various joint operations with third parties. Where a collaboration is deemed to be a joint operation the Group recognizes:

F-16

Table of Contents
Notes to the Financial Statements for the years ended 31 December, 2023, 2022 and 2021
its assets, including its share of any assets held jointly;
its liabilities, including its share of any liabilities incurred jointly; and
its expenses, including its share of any expenses incurred jointly.
The Group incurs expenses that under the joint operation agreement are to be shared jointly with the collaboration partner. Amounts reimbursed are recorded as a reduction in the underlying expenditure. Where amounts are reimbursed in advance of the Group incurring the expenditure, the amounts received are recognised as a liability in other advances. The other advances are extinguished when the expenditure to which the reimbursement relates is incurred.
p)    Leases
Leases are recognised as a right-of-use asset and a corresponding liability at the date at which the leased asset is available for use by the Group, and each lease payment is allocated between the liability and finance cost. The finance cost is charged to profit or loss over the lease period so as to produce a constant rate of interest on the remaining balance for the liability for each period. The right-of-use asset is depreciated over the shorter of the asset’s useful life and the lease term on a straight-line basis.
Assets and liabilities arising from a lease are initially measured on a present value basis. Lease liabilities include the present value of the following lease payments:
Fixed payments, less any lease incentive receivable;
Variable lease payments that are based on an index or a rate;
The exercise price of a purchase option if the lessee is reasonably certain to exercise
that option; and
Payments of penalties for terminating the lease, if the lease term reflects the lessee exercising that option.

The lease payments are discounted using the interest rate implicit in the lease. If this rate cannot be determined, the Group’s incremental borrowing rate (i.e. the rate that the Group would have to pay to borrow the funds necessary to obtain an asset of similar value in a similar economic environment with similar terms and conditions) is used.
Variable lease payments that reflect changes in market rental rates are initially measured using the market rental rates as at the commencement date. Variable lease payments that do not depend on an index or a rate are not included in the measurement of lease liabilities and right-of-use assets, and are recognized as expenses in the period in which the event or condition that triggers the payment occurs.
The right-of-use assets are measured at cost which comprise the following:
The initial measurement of lease liability;
Lease payments made at or before the commencement date (less lease incentives received);
Initial direct costs; and
Restoration costs.

Extension and Termination Options.
The Group determines the lease term as the non-cancellable term of the lease, together with any periods covered by an option to extend the lease if it is reasonably certain to be exercised, or any periods covered by an option to terminate the lease, if it is reasonably certain not to be exercised.


F-17

Table of Contents
Notes to the Financial Statements for the years ended 31 December, 2023, 2022 and 2021
Lease Modifications. The Group remeasures the lease liability (and makes a corresponding adjustment to the related right of use asset) whenever:
The lease term has changed or there is a significant event or change in circumstances resulting in a change in the assessment of exercise of a purchase option, in which case the lease liability is remeasured by discounting the revised lease payments using a revised discount rate.
The lease payments change due to changes in an index or rate or a change in expected payment under a guaranteed residual value, in which cases the lease liability is remeasured by discounting the revised lease payments using an unchanged discount rate (unless the lease payments change is due to a change in a floating interest rate, in which case a revised discount rate is used).
A lease contract is modified, and the lease modification is not accounted for as a separate lease, in which case the lease liability is remeasured based on the lease term of the modified lease by discounting the revised lease payments using a revised discount rate at the effective date of the modification.
Short-term and Low Value Leases. The Company does not recognize right-of-use assets for short-term and low value leases. Payments associated with short-term leases (leases of less than twelve months duration) and leases of low-value assets are recognised on a straight-line basis over the lease term
Impairment. The Group applies IAS 36 to determine whether a right-of-use asset is impaired and accounts for any identified impairment loss.

q)    Provisions
Provisions are recognised when the Group has a present obligation (legal or constructive) as a result of a past event, it is probable that the Group will be required to settle that obligation and a reliable estimate can be made of the amount of the obligation.The amount recognised as a provision is the best estimation of the considerations required to settle the present obligation at the reporting date, considering the risks and uncertainties surrounding the obligation.
Provisions for the cost to restore leased property to their original condition, as required by the terms and conditions of the lease, are recognised when the obligation is incurred, either at the commencement date or as a consequence of having used or made alterations to the underlying asset during a particular period of the lease, at the Directors’ best estimate of the expenditure that would be required to restore the assets. Estimates are regularly reviewed and adjusted as appropriate for new circumstances.
Provisions for onerous contracts are recognised when the unavoidable costs of meeting the obligations under a contract exceed the economic benefits expected to be received, and are based on the Group's best estimate of the present value of the outflows incurred in fulfilling/exiting the contract net of any associated inflows.

r)    Pension Costs
The Group operates a defined contribution pension scheme for employees. The assets of the scheme are held separately from those of the Group. The annual contributions payable are charged to the Group profit or loss on an accruals basis.



F-18

Table of Contents
Notes to the Financial Statements for the years ended 31 December, 2023, 2022 and 2021
s)    Financial Instruments
Financial Assets. Financial assets classified as financial instruments measured at amortised cost comprise trade and other receivables and cash and cash equivalents and short term bank deposits. Financial assets measured at amortised cost are recognised when the Group becomes party to the contractual provisions of the instrument and are derecognised when the contractual rights to the cash flows from the financial asset expire or when the financial asset and all substantial risks and reward are transferred. Financial assets are measured at amortised cost when both of the following criteria are met:
The financial asset is held within a business model whose objective is to hold financial assets in order to collect contractual cash flows; and
The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amounts outstanding.
Subsequent to initial recognition, financial assets are measured at amortised cost using the effective interest rate method. At each reporting date the Group recognizes a loss allowance for expected credit losses on financial assets measured at amortised cost. In establishing the appropriate amount of loss allowance to be recognised, the Group applies either the general approach or the simplified approach, depending on the nature of the underlying group of financial assets. Further details are set out in Note 27.
Classification as Debt or Equity. Debt and equity instruments are classified as either financial liabilities or as equity in accordance with the substance of the contractual arrangements and the definitions of a financial liability and an equity instrument.
Equity Instruments. Equity instruments constitute any contract that evidences a residual interest in the assets of an entity after deducting all of its liabilities. Equity instruments such as preference shares issued by the Group are recognised at the proceeds received, net of direct issue costs. All preference shares in issue throughout 2021 were convertible into ordinary shares under certain conditions and bore no fixed or cumulative dividend. As such these shares were deemed to be equity in nature.
Following the achievement of a development milestone relating to the Group’s revenue contract with GT Apeiron Therapeutics Inc. (“GTA”) on March 31, 2021, the Group became entitled to receive a number of ordinary shares and preference shares in this company as non-cash revenue consideration (see note 27 for further details). These shares represent unlisted equity securities and the Group has taken the election provided within IFRS9 to recognize fair value gains and losses within Other Comprehensive Income (FVOCI).
Financial Liabilities.Financial liabilities comprise trade and other payables as well as loan liabilities. Financial liabilities are obligations to pay cash or other financial assets and are recognised in the statement of financial position when, and only when, the Group becomes a party to the contractual provisions of the instrument.
Financial liabilities are initially recognised at fair value adjusted for any directly attributable transaction costs. After initial recognition, financial liabilities are measured at amortised cost using the effective interest method, with interest-related charges recognised as an expense in finance costs.
A financial liability is derecognised only when the contractual obligation is extinguished, that is, when the obligation is discharged, cancelled or expires.


F-19

Table of Contents
Notes to the Financial Statements for the years ended 31 December, 2023, 2022 and 2021
Derivative Financial Instruments- Forward Contracts. Derivative financial instruments relating to currency forward contracts are initially recognised at fair value on the date at which the derivative contract is executed, and are subsequently re-measured at fair value each period-end. Any gains and losses arising from changes in the fair value of derivatives are recognised within the consolidated statement of profit or loss.

t)    Share-based Payments
The Group operates equity-settled share-based compensation plans whereby certain employees of the Group are granted equity awards in the Company in the form of share options, restricted share units (“RSUs”), performance options and performance share units.
The fair value of awards granted is recognised as an expense within profit or loss with a corresponding increase in equity. The fair value of the award is measured at the grant date and is spread over the period during which the respective employee becomes unconditionally entitled to the award. The fair value of share options and those performance option and PSU awards not containing market-based performance conditions are valued using a Black-Scholes model, while performance options and PSUs containing market-based conditions are valued using a Monte-Carlo model. The fair value of RSUs is based on the market value of the underlying shares at the award grant date.
At each statement of financial position date, the Group revises its estimate of the number of awards that are expected to become exercisable based on forfeiture rates, and with the exception of changes in the estimated probability of achieving market-based performance conditions, adjustments are made such that at the end of the vesting period the cumulative charge is based on the number of awards that eventually vest.
Where the terms and conditions of options are modified before they vest, the increase in the fair value of the options, measured immediately before and after the modification, is also recognised in profit or loss over the remaining vesting period. There were no modifications to the terms and conditions of options during the current or previous financial period.
When a share based payment award is exercised an intra-equity movement is recorded to transfer the cumulative charge recorded within the share-based payment reserve for those awards to retained earnings.

u)    Tax
Tax on the loss for the year comprises current and deferred tax. Tax is recognised in the profit or loss account except to the extent that it relates to items recognised directly in equity, in which case it is recognised in equity.
Current Tax. Current tax is provided at the amounts expected to be paid applying tax rates that have been enacted or substantively enacted by the balance sheet date. Current tax includes tax credits, which are accrued for the period based on calculations that conform to the U.K. Research and Development Tax Credit Scheme that is applicable to small and medium sized companies.
Research and development costs which are not eligible for reimbursement under the U.K. Research and Development Tax Credit scheme, such as expenditure incurred on research projects for which the group receives income, may be reimbursed under the U.K. R&D expenditure credit (“RDEC”) scheme.

F-20

Table of Contents
Notes to the Financial Statements for the years ended 31 December, 2023, 2022 and 2021
Amounts receivable under the RDEC scheme are presented within other income. Research and development expenditure credits are also claimed in Austria in relation to qualifying expenditure incurred on research projects by the Group’s Austrian subsidiary. These amounts are also presented within other income.
Deferred Tax. Deferred taxes are calculated using the liability method on temporary differences between the carrying amounts of assets and liabilities and their tax bases. A deferred tax asset is recognised for all deductible temporary differences to the extent that it is probable that taxable profit will be available against which the deductible temporary difference can be utilised, unless the deferred tax asset arises from the initial recognition of an asset or liability in a transaction that is not a business combination and at the time of the transaction, affects neither accounting profit nor taxable profit (tax loss). However, for deductible temporary differences associated with investments in subsidiaries a deferred tax asset is recognised when the temporary difference will reverse in the foreseeable future and taxable profit will be available against which the temporary difference can be utilised.
Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realised or the liability is settled, based on tax rates and tax laws that have been enacted or substantively enacted by the end of the reporting period. Deferred tax assets and liabilities are set off only where the Group has a legally enforceable right to set off the recognised amounts and the Group intends either to settle on a net basis or to realize the asset and settle the liability simultaneously.

v)    Research and Development Costs
Research costs are expensed as incurred. Development expenditures on an individual project are recognised as an intangible asset when the Group can demonstrate:
the technical feasibility of completing the intangible asset so that it will be available for use or sale;
its intention to complete and its ability to use or sell the asset;
how the asset will generate future economic benefits;
the availability of resources to complete the asset; and
the ability to measure reliably the expenditure during development.
Following initial recognition of the development expenditure as an asset, the cost model is applied requiring the asset to be carried at cost less any accumulated amortisation and accumulated impairment losses. Amortisation of the asset begins when development is complete, and the asset is available for use. It is amortised over the period of expected future benefit. Amortisation is recorded in research and development costs. During the period of development, the asset is tested for impairment annually. No expenditure met the criteria for capitalisation during the current or prior years.

3.Critical Accounting Estimates and Judgements
In the application of the Group’s accounting policies the directors are required to make judgements, estimates and assumptions about the carrying amounts of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.


F-21

Notes to the Financial Statements for the years ended 31 December, 2023, 2022 and 2021
Critical Accounting Estimates
The estimates and underlying assumptions are reviewed on an ongoing basis. The critical estimates that the directors have made in the process of applying the Group's accounting policies that have the most significant effect on the amounts recognised in the financial statements are discussed below.
Recognition of Revenue. Revenue is recognised upon the satisfaction of performance obligations, which occurs when control of the good or service transfers to the customer. Control transfers over time in relation to the majority of research and design activities performed during the years ended December 31, 2023 and 2022. Total or external costs or labour hours incurred are utilised as the relevant input method in order to estimate the extent to which the performance obligations satisfied over time have been satisfied at the end of the reporting period depending on the nature of the arrangement. Estimation of the future costs to be incurred in the satisfaction of performance obligations delivered over time, inclusive of any costs relating to the substitution of targets where allowed in accordance with a specific collaboration agreement, is considered to be a key source of estimation uncertainty in relation to the recognition of revenue in any given period.
No changes to estimated total projected costs were noted during the years ended December 31, 2023 and 2022 that had a significant impact on revenues recognised during the period.
The table below illustrates the sensitivity analysis of the Group’s reported profit to a 10% increase or decrease in the estimated future costs to be incurred in the delivery of partially unsatisfied performance obligations relating to the Group’s revenue contracts as at December 31, 2023.
Change in Estimated Future CostsEffect on Profit Before TaxEffect on Equity
£’000£’000
Impact on change in the estimated future costs to be incurred in delivering partially unsatisfied performance obligations+10 %(1,145)(1,145)
-10 %1,289 1,289 

Revenue from potential milestones or royalties are not recognised at the initiation of a contract. Upfront payments that include performance obligations are recognised as those obligations are satisfied. In addition no profit is recognised as costs are incurred until such a time as costs and time to programme completion can be reasonably estimated, with revenues recognised equal to a percentage of costs incurred until that time. As a result of this, until total costs and time to completion can be reliably estimated, a gross loss may be recognised on individual customer contracts despite the expectation that the relevant contract will be profitable overall.
Leases. The Group has entered into lease arrangements pertaining to various premises globally, in relation to which it assesses whether the lease arrangements constitute onerous contracts at the end of each reporting period.

F-22

Table of Contents
Notes to the Financial Statements for the years ended 31 December, 2023, 2022 and 2021
In December 2022, the Group entered into a lease arrangement in relation to premises in Miami, Florida, United States, with the lease term due to commence in the first quarter of 2024. Subsequent to entering into the above arrangement, as a result of the Group's cost containment measures, the decision was taken not to occupy these premises, and instead to lease smaller premises nearby. Total minimum lease commitments of £3,040,000 are payable under this arrangement, and as such the Group must assess whether an onerous contract exists for which a provision is required.
The Group has engaged an agent to assist in arranging the subleasing of the original leased premises to a third party, and has estimated that the present value of the unavoidable costs of meeting the Group's obligations under the contract exceed the expected benefits to be received from subletting the space by £807,000 as at December 31, 2023, with such amount being recorded within provisions at that date.
No other onerous lease provisions or ROU asset impairments have been deemed necessary as at December 31, 2023.

Under the terms of the Company’s private placement with the Gates Foundation, the latter has the right to sell, or require the Group to buy-back any shareholdings in the Group held by the Gates Foundation at the higher of the public offering price and the market value of the shares if the Group is in breach of certain terms within the agreement. This right constitutes a derivative financial liability for the Company which is recognised at fair value through profit or loss. The Group has assessed the likelihood of a default occurring as low as at December 31, 2023, and as such the fair value of this liability has been estimated as nil at the balance sheet date.
Fair Value of the Group’s Investment in GTA. As at December 31, 2023 the Group holds a number of ordinary and preference shares in GTA at fair value through other comprehensive income. GTA is an unlisted early-stage business, with projects in the discovery and clinical stages of drug development which are pre-revenue generation. As such the key source of estimation uncertainty is the value per share of these unlisted equity securities. The shares in question are very illiquid, and the primary valuation input is cost or the price of latest investment where third party share acquisition transactions have taken place adjusted to reflect other factors as appropriate.
The Group has also assessed the impact of the current war in Ukraine and the conflict between Hamas and Israel on this investment, and does not consider that any revaluation is required as a result of these events. Finally the Group has assessed changes in relevant market equity indexes, with specific reference to changes in the NASDAQ Biotechnology Index over the period in question, with no revaluation required as a result.
Goodwill and Pharmacoscopy IP Intangible Impairment. The Group assesses annually, or whenever there is a change in circumstances, whether goodwill or acquired IP may be impaired. Determining whether an impairment exists requires estimation of the recoverable amount of the CGU to which the goodwill and acquired IP relate, being equal to the higher of its value in use and fair value less costs to sell.
The value in use calculation is judgmental in nature, and requires the Group to make a number of estimates relating to the future cash flows expected to arise from the CGU spanning drug discovery, development, regulatory approval and commercialisation, as well as a suitable discount rate in order to calculate present value.

The cash flow projections are further risk adjusted based on observable market comparables to take into account the probability of successfully commercialising a drug at each stage of its development. Sensitivity analysis is performed in order to determine whether reasonable changes in significant assumptions would lead to the carrying value exceeding its recoverable amount. When the carrying value of the CGU exceeds its recoverable amount, the CGU is considered impaired and the assets in the CGU are written down to their recoverable amount. Impairment losses are recognised in the consolidated statement of loss and other comprehensive income.
A detailed impairment assessment was performed as of December 31, 2023, with no impairment noted and no reasonable changes in significant assumptions were identified that would lead to the carrying amount exceeding its recoverable amount.
Accounting Judgements
In the process of applying the Group’s accounting policies, management has made the following judgements which have the most significant effect on the amounts recognised in the financial statements:
Recognition of Revenue. Management judgement is required to determine the performance obligations under each agreement and appropriately allocate revenue to the identified performance obligations in line with IFRS 15. Judgement is also required in determining the point at which the total costs to be incurred in delivering a performance obligation can be reliably estimated such that revenue can be recognised in excess of recoverable costs incurred. Judgement is also required in estimating the likelihood of and costs that may be incurred in relation to the substitution of targets where allowed in accordance with a specific collaboration agreement.
Further judgement is required to determine whether sources of variable consideration are constrained as at the end of the reporting period as a result of it not being highly probable that a significant reversal in the amount of cumulative revenue recognised would not occur when the uncertainty associated with the variable consideration is subsequently resolved. Constraint is typically considered to be removed in relation to milestone/opt-in amounts when written confirmation of achievement has been provided by the counterparty or achievement has been ratified at a project Joint Steering Committee.
Loss-making Collaboration Arrangements. Management judgement is required in order to determine whether the unavoidable costs of meeting the obligations under each customer collaboration arrangement, inclusive of both costs that relate directly to the contract and an allocation of other costs, exceed the economic benefits expected to be received under it. Where such costs are in excess of the Group’s best estimate of future revenues to be generated from the arrangement a provision is recorded in accordance with IAS 37.
The company has assessed the value of the remaining transaction price relating to the outstanding performance obligations relative to the value of the estimated remaining unavoidable costs of meeting the obligations under contracts relating to the Group’s customers and determined that no onerous contract provision is required as at December 31, 2023.

4.Operating Segments
The Group manages its operations as a single segment for the purposes of assessing performance and making operating decisions. Operating segments are defined as components of an enterprise for which separate financial information is regularly evaluated by the Group’s chief operating decision maker, or decision-making group, in deciding how to allocate resources and assess performance. The Group has determined that its chief operating decision maker is its Interim Chief Executive Officer.
Information on Major Customers. Revenue recognised during the years ended December 31, 2023, 2022 and 2021 relates to collaboration agreements with Bristol Myers Squibb Company (“BMY”), Celgene Switzerland LLC (“Celgene”) (a company acquired by BMY subsequent to the inception of the collaboration), Sanofi S.A. (“Sanofi”), Merck KGaA, Darmstadt, Germany (“Merck KGaA, Darmstadt, Germany”), Bayer AG (“Bayer”), GTA, and the Group’s joint venture with RallyBio IPB, LLC (“RallyBio”), RE Ventures I, as well as legacy contracts operated by the Group’s Austrian subsidiary.

5.Revenue
The Group’s revenue by type during 2023, 2022 and 2021 are as follows:
December 31,
202320222021
£’000£’000£’000
Service fees104 670 452

Licensing fees - recognised over time19,975 26,553 8,324 
20,079 27,223 27,359 
Revenue is recognised upon the satisfaction of performance obligations, which occurs when control of the goods or services transfers to the customer. For obligations discharged over time, the Group recognises revenue equal to recoverable costs incurred for new collaborations from their inception until such time as the collaboration is sufficiently progressed such that the Group can reliably estimate the level of profit that will be achieved from delivery of the related performance obligations. Where collaborations include significant variable consideration which is constrained at the inception of the arrangement this can lead to gross losses being recognised during the early stages of a contract.
Service fees during the year ended December 31, 2023, 2022 and 2021 relate to revenues generated from legacy contracts held by Exscientia GmbH, in relation to which revenue is recognised at a point in time.
During the year ended December 31, 2021, £14,437,000 was recognised in relation to a candidate opt-in milestone achieved in respect of the Group’s collaboration with Celgene, in addition to £3,349,000 recognised as revenue in relation to a candidate selection milestone achieved in respect of the Group’s collaboration with GTA.
On January 4, 2022 the Group entered into a strategic research collaboration with Sanofi to develop an AI-driven pipeline of precision engineered medicines. Research will be focused on up to 15 novel small molecule candidates across oncology and immunology, in relation to which the Group will receive an up-front cash payment of £74,242,000 ($100,000,000) with the potential of $5,200,000,000 in total milestones plus tiered royalties over the duration of the collaboration.
On March 11, 2022, BMY extended its first collaboration arrangement with the Group by six months in order to generate additional data including the use of translational capabilities for key targets under the collaboration using the Group’s precision medicine platform, in relation to which the Group received a cash payment of $5,000,000 (£3,821,000).The term extension payment has been treated as an addition to the transaction price relating to the collaboration’s partially unsatisfied performance obligations relating to the design and development of candidates for collaboration targets, with a cumulative recognition of revenue at that date based upon the progress towards satisfaction of the related performance obligations in accordance with paragraph 21b of IFRS 15. The remaining element of the transaction price was recognised as revenue over the remainder of 2022 as the performance obligations were satisfied.
On May 30, 2022, the Group ended its pre-existing collaboration arrangement with Bayer AG by mutual agreement. Upon ending the agreement all remaining performance obligations pertaining to the contract were deemed to be fully discharged, resulting in the recognition of revenues totalling £1,153,000 at that point.

Notes to the Financial Statements for the years ended 31 December, 2023, 2022 and 2021
On July 27, 2023 the Group and Sanofi S.A. entered into an amendment to the collaboration agreement executed between the parties on January 4, 2022, pursuant to which certain terms, including with respect to certain target substitution and milestone payments, relating to targets under the collaboration were amended. There was no change to the overall contract transaction price as a result of the amendment, and no significant adjustment to revenue recognised on partially satisfied performance obligations as at the amendment date.
On September 19, 2023 the Group and the Healthcare Business of Merck KGaA, Darmstadt, Germany (“Merck KGaA, Darmstadt, Germany”), entered into a collaboration agreement focused on the discovery of novel small molecule drug candidates across oncology, neuroinflammation and immunology using Exscientia’s AI-driven precision drug design and discovery capabilities. Three potential first-in-class or best-in-class targets have been identified as the initial focus of the partnership, in relation to which the Group received an up-front cash payment of $20,100,000 (net of withholding taxes of $3,181,000 which are expected to be received in the second half of 2024), with the potential of up to $674,000,000 in discovery, development, regulatory and sales-based milestones in addition to royalty payments on net sales.
On September 27, 2023 the Group received confirmation of the achievement of a research milestone in the Group’s collaboration with Sanofi for its first inflammation and immunology target, in relation to which it received a cash payment of £3,191,000 ($4,000,000). Until achievement, this milestone was treated as constrained variable consideration relating to the drug design work undertaken in relation to the associated project, and as such it has been added to the transaction price for the related partially satisfied performance obligation from the point of achievement, with revenue recognised as the performance obligation is satisfied.
On December 21, 2023, the Group amended its current collaboration with Sanofi to add a new discovery stage programme identified and initially advanced by Exscientia, in relation to which a cash payment of $4,000,000 was received in February 2024, with revenue recognised over time as the related performance obligation is satisfied. Under the terms of the amended agreement the Group is eligible to receive up to $45,000,000 in upfront and preclinical milestone payments, as well as development, regulatory and sales-based milestone payments of over $300,000,000 and tiered royalties on product sales.
Included within revenues during the year ended December 31, 2023 are amounts totalling £6,859,000 relating to non-refundable upfront payments on projects under the Group’s ongoing collaboration with BMY which have been recognised as revenue during the year as it has been mutually determined not to proceed with further development of these projects and prioritise others within the collaboration.
The Group has assessed its significant collaboration arrangements with commercial partners and determined that no provision for future operating losses is required as at December 31, 2023, taking into account expected future cash inflows and remaining contract liability amounts for each collaboration relative to the remaining unavoidable costs of meeting the respective contracts’ obligations in each instance.

Factors That May Affect Future Tax Charges:
In the Spring Budget 2021, the U.K. Government announced that from April 1, 2023 the corporation tax rate would increase to 25% (rather than remaining at 19%, as previously enacted). This new law was substantively enacted on May 24, 2021. For the financial year ended December 31, 2023, the current weighted average tax rate was 23.5%. Deferred taxes at the balance sheet date have been measured using the enacted 25% tax rate, and reflected within these financial statements.
The Group currently surrenders losses relating to eligible U.K. research and development expenses for a cash rebate of up to 33.35% under the U.K. SME scheme. The SME Programme cash rebate rate reduced to 18.6% for qualifying research and development expenditure incurred on or after April 1,2023, with this rate being applied in order to calculate the SME cash rebate recorded within these financial statements.

F-32

Table of Contents
Notes to the Financial Statements for the years ended 31 December, 2023, 2022 and 2021
Amendments to the U.K. R&D tax credit regime that are contained in the recently enacted Finance Bill increase the cash rebate that may be claimed from such date to 26.97% of qualifying expenditure, if we qualify as an “R&D-intensive SME” for an accounting period (broadly, a loss making SME whose qualifying R&D expenditure represents 40% (or, from April 1, 2024, 30%) or more of its total expenditure for that accounting period. If it is determined that we qualified as an R&D-intensive SME for the accounting period ended December 31, 2023 (and as such that the cash tax rebate for the period April 1, 2023 to December 31, 2023 can be claimed at 26.97% of eligible expenditure rather than the 18.6% rate currently utilised), the expected impact would be to increase the income tax benefit for the year to December 31, 2023 by £3,961,000.
Additionally, amendments will come in effect from April 1, 2024 that (i) (unless limited exceptions apply) introduce restrictions on the tax relief that can be claimed for expenditure incurred on sub-contracted R&D activities or externally provided workers, where such sub-contracted activities are not carried out in the U.K. or such workers are not subject to U.K. payroll taxes, and (ii) merge the SME Program and the RDEC Program into a single scheme. If we do not qualify as an R&D-intensive SME, we will either cease to be able to claim cash rebates in respect of our R&D activities, or only be able to receive such cash rebates at a significantly lower rate than at present. These and other potential future changes to the U.K. R&D tax relief programmes may mean we no longer qualify for them or have a material impact on the extent to which we can make claims or benefit from them.

Basic and Diluted loss per share (£)(1.18)(0.97)(0.99)

Basic loss per share is calculated in accordance with IAS 33 (“Earnings per Share”) based on earnings attributable to the Company’s shareholders and the weighted average number of shares outstanding during the period.
Concurrent with the Company’s IPO on October 05, 2021 all of the ordinary and preference shareholders of Exscientia plc exchanged each of the existing shares held by them for 300 newly issued Ordinary shares of £0.0005 each in the Company. The ordinary shares outstanding used for computation of loss per share in all periods reflect this share split, consistent with the principles in IAS 33 paragraph 64.
The Company issues performance share options, share options, restricted share units (“RSUs”) and performance share units (“PSUs”) to employees, upon the exercise of which ordinary shares are issued. Inclusion of these awards would have an anti-dilutive effect on the loss per share due to the loss incurred during the period, therefore basic and diluted loss per share are the same.

Goodwill and Acquired IP- Allcyte Acquisition. On August 18, 2021 the Group acquired intellectual property with a fair value of £36,078,000 relating to the pharmacoscopy technology utilised by Allcyte as part of the acquisition of that company. The IP is being amortised over a period of 8 years from the acquisition date. No indicators of impairment were noted in relation to the pharmacoscopy IP as at December 31, 2023.
Goodwill totalling £5,887,000 was also acquired as part of that acquisition, representing the additional value expected to be derived by the Group from the acquisition, as well as the assembled workforce.
The Group consists of one CGU relating to its drug discovery activities. An impairment review was performed in relation to the goodwill and pharmacoscopy IP as at December 31, 2023 by comparing the recoverable amount of the CGU to its carrying value using a value in use model. A discounted cashflow methodology was utilised, with key assumptions relating to the number of internal and partnership programs delivered by the Group, the duration of and total costs relating to each phase of the drug development, the costs of completing clinical trials and obtaining certain regulatory approvals, and product sales volumes and the time period to patent expiry once regulatory approvals have been achieved. A probability of success was then applied to each phase of the drug development in order to reflect the possibility that the drug may not be successfully commercialised.

Other key inputs relate to costs incurred relating to other operational and administrative overheads and capital expenditure. Cashflows were projected over a 20 year period, with the period in question deemed appropriate based on the time taken to design, develop, and commercialise drugs through to patent expiry once regulatory approvals have been achieved. A terminal value growth rate of 2.0% was applied thereafter.
Cashflows determined by the model were then discounted to present value using a discount rate of 14%. The assumptions are based from industry literature and, where possible, the Group's experience of developing drug candidates. No impairment was noted as a result of this review. Sensitivity analysis was performed in order to determine whether reasonable changes in significant assumptions would lead to the carrying value exceeding its recoverable amount, this showed no reasonably possible change that would result in an impairment.
Acquired IP- GT Apeiron Collaboration. On July 1, 2021 the Group entered into a joint operation with GTA in order to build a sustainable pipeline of high-value, best in class therapeutics. As part of this arrangement the pre-existing collaboration arrangement between the two parties was terminated, the Group made a payment of £1,448,000 and waived the rights to 30% of the shares in GTA that became receivable following the achievement of a milestone on the pre-existing collaboration agreement, with the total fair value of these amounts of £2,543,000 capitalised as an acquired IP intangible at that date. The intangible relates to the IP in the pre-existing collaboration target that the group gained joint control of as a result of its participation in the joint operation.
No amortisation charge has been recognised in relation to the IP during the period and as such the asset was reviewed for impairment on December 31, 2023. A value in use assessment was performed in order to determine that the asset's recoverable amount is in excess of its carrying amount. A discounted cashflow methodology was utilised, with key assumptions relating to the duration of and total costs relating to each phase of the drug development, the costs of completing clinical trials and obtaining certain regulatory approvals, and product sales volumes and the time period to patent expiry once regulatory approvals have been achieved. A probability of success was then applied to each phase of the drug development in order to reflect the possibility that the drug may not be successfully commercialised. Cashflows determined by the model were then discounted to present value using a discount rate of 14%. Cashflows were projected over a 20 year period, with the period in question deemed appropriate based on the time taken to design, develop, and commercialise drugs through to patent expiry once regulatory approvals have been achieved. The assumptions are based from industry literature and, where possible, the Group's experience of developing similar drug candidates. No impairment was noted.
Goodwill- Kinetic Discovery Acquisition. Goodwill amounting to £173,000 arose on the acquisition of Kinetic Discovery Limited on November 23, 2018. No impairment review was performed at December 31, 2023 given the value of this goodwill is deemed to be immaterial.

During 2022 the Group established a further 50% joint venture with RallyBio, RE Ventures II, LLC, with the same aims. There have been no transactions with this entity and no capital contributions were made from its inception to December 31, 2023.

Joint Operations
Exscientia has a joint contractual arrangement with Evotec AG, which originally entitled each party to 50% ownership over three novel compounds under the collaboration. The joint operation is not structured through a separate legal entity, and it operates from Exscientia and Evotec AG’s respective principal places of business. Evotec exercised its opt-out rights in relation to the arrangement in April 2021, revising downwards their ownership rights at each stage of development of the collaboration's intellectual property, with their ownership rights at 40% as at December 31, 2023. Evotec's ownership reduces further at future stages of development, subject to a minimum level at commercialisation of 10%. As at January 1, 2023 activities were ongoing in relation to one novel compound, EXS21546 ('546). On October 3, 2023 the Company announced that it was discontinuing internal development on '546.
A joint contractual arrangement was entered into between Exscientia and Blue Oak Pharmaceuticals Inc. (“Blue Oak”) on September 25, 2020. On August 8, 2023, Exscientia and Blue Oak Pharmaceuticals Inc. ended this collaboration agreement. The purpose of this arrangement was to collaborate on a project to design dual targeted (bispecific) small molecules for the treatment of neurodegenerative diseases. No settlement amounts were paid as a result of the termination and no impairments of assets were recorded. Both parties retain the right to operate within the target area.
On May 26, 2021 the Group entered into a joint operation with EQRx Inc. (“EQRx”), a Delaware corporation to identify, discover and develop innovative drug candidates for high value therapeutics. The collaboration was ended on October 9, 2023 following the announcement of the acquisition of EQRx by Revolution Medicines Inc., at which point it was agreed that the Group would return the agreed unspent funds advanced to it by EQRx at the initiation of the collaboration in complete satisfaction of the Group’s financial obligations under the collaboration agreement. As part of the arrangement, the Group obtained full and exclusive rights to all intellectual property on the three initial targets that was created during the collaboration. Accordingly, $8,750,000 was transferred to EQRx on October 12, 2023.
On July 1, 2021 the Group entered into a joint operation with GTA as described in note 14 above. The aim of the collaboration is to accelerate the discovery of multiple small molecule therapeutic drug candidates designed to selectively treat aberrant cell cycle driven cancers and build a pipeline of CDK novel therapies, with equal ownership of any pipeline products resulting from the collaboration and costs incurred shared equally between the two parties.

On November 14, 2022 Exscientia entered into a joint operation with MD Anderson to leverage AI in developing novel oncology treatments. The research collaboration will utilise Exscientia’s precision medicine platform to identify novel anti-cancer, cell-intrinsic small-molecule compounds based on jointly identified therapeutic targets. Promising candidates will advance for further development with the team at MD Anderson’s Therapeutics Discovery division. MD Anderson and Exscientia anticipate that successful target discovery programs may be advanced into proof-of-concept clinical trials at MD Anderson. Under the agreement terms, Exscientia and MD Anderson will jointly contribute to and support each program designated to move forward. Any collaboration IP will then be jointly owned with percentage ownership dependent upon costs incurred, with a target cost-sharing ratio of 50%.
No collaboration IP has been capitalised in relation to any of the above joint operations as at December 31, 2023 and 2022 with the exception of the acquired IP intangible relating to the Group's collaboration with GTA as described in note 14.

All right-of-use assets relate to leased properties. As at January 1, 2023 the Group had ten pre-existing lease agreements relating to four properties based in the United Kingdom and one in Austria.
The Group entered into two seven-year lease arrangements in relation to laboratory and office space in Vienna, Austria on September 3, 2021. The lease term for the office space commenced on December 1, 2022, expiring in December 2029. The lease term for the laboratory space commenced on January 26, 2023. Annually from January, each year lease payments will be indexed based on the consumer price index rate as published by STATISTIK AUSTRIA at September of the preceding year.
On July 1, 2022, the Group entered into a lease arrangement in relation to premises in Boston, Massachusetts, United States. The lease commenced on January 23, 2023 and expires on June 23, 2033.
In December 2022, the Group entered into a lease arrangement in relation to premises in Miami, Florida, United States. The lease commencement date, being the date at which the landlord makes the premises available to the Group, is currently expected to transpire during the first quarter of 2024, and as such no right of use asset has been recognised in relation to this lease during the year ended December 31, 2023. The lease expires on June 1, 2034. See note 3 for further details regarding this lease.
On October 16, 2023 the Group entered into a second lease arrangement in relation to premises in Miami, Florida which expires on January 31, 2029.
Right-of-use assets totalling £6,692,000 were recognised in relation to the Group's leased premises in Vienna, Miami and Boston leases during the year ended December 31, 2023.
On May 23, 2023, the Group exited a lease pertaining to part of its leased premises in Dundee, United Kingdom, resulting in a disposal of right-of-use asset of £157,000.
On December 28, 2023, the Group made the decision to not exercise a break clause present within one of the leases on a building at one of our Oxford sites. The lease term was subsequently revised to the lease expiration date of July, 28, 2028, and the related right of use lease asset increased by £742,000. An adjustment was also made to increase the restoration provision relating to this site by £84,000 as a result of the change in lease term.
Restoration provisions of £200,000 and £500,000 were made during 2022 in respect of the Group’s obligation to restore alterations made during the period on leased spaces in two of the Group’s leasehold properties. The required work is expected to be completed in 2026 and 2031 respectively.

23.Deferred Tax
United Kingdom
The Group has recognised deferred tax assets and liabilities at December 31, 2023 and 2022. In light of the Group’s history of losses, recovery of the whole deferred tax asset is not sufficiently certain, and therefore a deferred tax asset has been recognised only to the extent that there is a deferred tax liability in the form of fixed asset temporary differences.
The unrecognised deferred tax asset of £57,658,000 (2022: £42,358,000) relates to short term timing differences of £40,788,000 (2022: £31,372,676) and losses and other deductions of £202,495,000 (2022: £167,305,000) offset by underlying fixed asset timing differences of £11,985,000 (2022: £29,247,000).

Additions to contract liabilities relating to revenue generating collaborations during the year ended December 31, 2023 include £16,238,000 ($20,100,000) invoiced to Merck KGaA, Darmstadt, Germany relating to the collaboration initiated with that counterparty on September 19, 2023, and amounts of £3,274,000 ($4,000,000) and £3,144,000 ($4,000,000) invoiced to Sanofi in relation to the achievement of a research milestone and the initiation of a new drug discovery project as detailed in note 5.
The Group’s collaboration with EQRx International, Inc. (“EQRx”) was ended on October 9, 2023 following the announcement of the acquisition of EQRx by Revolution Medicines Inc., at which point it was agreed that the Group would return the agreed unspent funds advanced to it by EQRx at the initiation of the collaboration in complete satisfaction of the Group’s financial obligations under the collaboration agreement. As part of the arrangement, the Group obtained full and exclusive rights to all intellectual property on the three initial targets that was created during the collaboration.
The Group expects to recognise its contract liabilities relating to revenue generating collaborations over the terms of the related collaborations, the longest of which extends to December 2027. As at December 31, 2022, the Group expected to recognise its contract liabilities relating to revenue generating collaborations over the period to December 2027. The ageing presented above reflects the Group’s best estimate of when contract liability and other advance amounts will be utilised based upon when the underlying costs to be incurred in the delivery of the related projects are expected to be incurred.

A provision of £535,000 was made during 2020 in respect of the Group’s obligation to restore alterations made on lease space within one of the Group’s leasehold properties. The required work is expected to be completed in 2024 and 2028.
Further provisions of £200,000 and £500,000 were made during 2022 in respect of the Group’s obligation to restore alterations made during the period on leased spaces in two of the Group’s leasehold properties. The required work is expected to be completed in 2026 and 2031 respectively.
An adjustment was made to increase the restoration provision relating to part of the Group's Oxford headquarters by £84,000 upon extension of the related lease. The required work is now expected to be completed in 2028.
Key uncertainties surrounding the amount and timing of the outflows relate to changes in required restoration costs over the lease term and the timing of exit of the relevant buildings.
A provision for costs relating to an onerous contract relating to one of the Group's leased premises was recorded during the year ended December 31, 2023, see note 3 for further details.

As disclosed throughout the financial statements, management consider fair value to be materially the same as the carrying amount. Other advances relating to amounts received from joint operation partners have been classified as financial liabilities and included within the tables above and below.
Classification of Financial Assets at Amortised Cost
The Group classifies its financial assets as at amortised cost only if both of the following criteria are met:
The asset is held within a business model with the objective of collecting the contractual cash flows, and
the contractual terms give rise on a specified date to cash flows that are solely payments of principal and interest on the principal outstanding.

Nature of Financial Instruments Recognised and Measured at Fair Value
Unlisted Equity Securities- Shares in GTA. Following the achievement of a development milestone on March 31, 2021, the Group became entitled to receive a number of ordinary shares and preference shares in GTA. These shares represent unlisted equity securities and the Group has taken the election provided within IFRS9 to recognize fair value gains and losses within Other Comprehensive Income (FVOCI) as gains and losses relating to the value of these securities are not considered to be part of the trading activities of the entity.
On July 1, 2021 the rights to a portion of these shares were waived as part of an agreement to enter into a joint arrangement with the Group as further detailed in note 14. The remainder of the shares in question were received on that date.

Notes to the Financial Statements for the years ended 31 December, 2023, 2022 and 2021
The Group’s current valuation for this investment has been established with reference to the price of third party investment into GTA in the first quarter of 2022, with no adjustment deemed necessary based on our assessment of internal and other market factors throughout the remainder of 2022 and 2023.
Foreign Exchange Forward Contracts. During the three months ended June 30, 2022 the Group entered into one specific set of foreign exchange transactions, whereby a commitment was made to exchange U.S. dollars for a fixed number of Pounds Sterling at future dates between one and three months from the trade dates based on the estimated future cashflow needs of the Group. All of the transactions were settled within the quarter ended June 30, 2022 for a cumulative loss of £11,287,000. No such transactions were entered subsequent to that date, and the group does not use derivative financial instruments for speculative purposes.
Fair Value Hierarchy. To provide an indication about the reliability of the inputs used in determining fair value, the group classifies its financial instruments into the three levels prescribed under the accounting standards as follows:
Level 1: The fair value of financial instruments traded in active markets (such as publicly traded derivatives and equity securities) is based on quoted market prices at the end of the reporting period. The quoted marked price used for financial assets held by the group is the current bid price. These instruments are included in level 1.
Level 2: The fair value of financial instruments that are not traded in an active market (for example, over–the–counter derivatives) is determined using valuation techniques which maximize the use of observable market data and rely as little as possible on entity-specific estimates. If all significant inputs required to fair value an instrument are observable, the instrument is included in level 2.
Level 3: If one or more of the significant inputs is not based on observable market data, the instrument is included in level 3. This is the case for unlisted equity securities.
The objective of valuation techniques is to arrive at a fair value measurement that reflects the price that would be received to sell the asset or paid to transfer the liability in an orderly transaction between market participants at the measurement date.

Risk Management Objectives. Management identifies and evaluates financial risks on an on-going basis. The principal risks to which the Group is exposed are market risk (including interest rate risk, and cash flow risk), credit risk, and liquidity risk.
Market Risk. Market risk is the risk that the fair value or future cash flows of financial instruments will fluctuate because of changes in market prices. For the Group, market risk comprise of two types of risks; interest rate risk and foreign currency risk.
Foreign Currency Risk. The Group is exposed to foreign currency exchange risks due to the Group holding foreign currency monetary assets and liabilities which are exposed to exchange rate fluctuations, primarily in relation to foreign currency denominated cash and cash equivalents as well as trade receivables. This risk is assessed on an on-going basis.
The Group does not have a policy to use derivative financial instruments to manage currency exchange movements, although they may be used for specific transactions, and as such, no hedge accounting is applied.
The table below illustrates the sensitivity analysis of the Group’s reported profit to a 10% increase or decrease in the respective foreign exchange rates to which they are significantly exposed. The sensitivity analysis is calculated on balances outstanding at the year end, with all other variables held constant.

-10 %(6,290)(6,051)
Change in EUR+10 %165 4,631 
-10 %(165)(4,631)
Interest Rate Risk. The Group’s exposure to the risk of changes in market interest rates relate to the Group’s interest-bearing current accounts. The Group has multiple instant access accounts including within cash and cash equivalents which are exposed to variable interest rates which total to £97,292,000 (2022: £370,868,000). A sensitivity analysis prepared with a 1% increase or decrease in interest rate with all other variables held constant would lead to an increase or decrease in profit and equity of £973,000 (2022: £3,709,000).
The sensitivity analysis has been determined based on the exposure to floating interest rate instruments at the end of the reporting year. The analysis is prepared assuming the amount of the consolidated balance at the end of the reporting year was the balance for the whole year.
Credit Risk. Credit risk refers to the risk that a counterparty will default on its contractual obligations resulting in financial loss to the Group. Credit risk arises from cash balances (including bank deposits, cash and cash equivalents) and credit exposures to trade and other receivables.

F-50

Table of Contents
Notes to the Financial Statements for the years ended 31 December, 2023, 2022 and 2021
The Group’s maximum exposure to credit risk is represented by the carrying value of cash and cash equivalents and trade and other receivables.
Credit risk is managed by monitoring clients and performing credit checks before accepting any customers and by placing funds with banks with high credit-ratings assigned by international credit-rating agencies.
Impaired Trade Receivables. Individual receivables which are known to be uncollectible are written off by reducing the carrying amount directly. There have been no impairments during 2023 (2022: £nil).
Expected Credit Losses. At each reporting date, the Group recognizes a loss allowance for expected credit losses on material balances by applying the simplified approach.
In applying the simplified approach, the Group uses a “probability of default” (“PD”) approach, to determine the lifetime expected credit losses. Under the PD approach, the expected credit losses are calculated using three main parameters:
a counterparty PD;
expected LGD (loss given default); and
EAD (expected exposure at default).

In calculating the expected credit loss, the following formula is applied:
Expected Credit Loss (ECL) = PD x LGD x EAD
Based on the nature of the Group’s activities and trade receivables being current, management has determined that the expected credit loss on these balances is not material at the reporting date.
Capital Management. The Group manages its capital to ensure that it will be able to continue as a going concern. The capital structure of the Group consists of issued capital, the share premium account and accumulated losses.
The Group manages its capital structure and makes adjustments to it in light of changes in economic conditions. No significant changes were made in the objectives, policies or processes during the years ended December 31, 2023 and December 31, 2022. The Group does not have any externally imposed capital requirements. As part of the Group’s management of capital structure, consideration is given to the cost of capital.
Liquidity Risk. Liquidity risk is the risk that the Group may encounter difficulty in meeting its obligations associated with financial liabilities that are settled by delivering cash or other financial assets. The Group seeks to manage its liquidity risk by ensuring that sufficient liquidity is available to meet its foreseeable needs.
A summary table with maturity of financial liabilities presented below is used by management to manage liquidity risks. The amounts disclosed in the following tables are the contractual undiscounted cash flows with the exception of advances received from joint operation partners, which are based on the Group's best estimate of when the underlying costs to which those advances relate are incurred.
Undiscounted cash flows in respect of balances due within 12 months generally equal their carrying amounts in the statement of financial position, as the impact of discounting is not material.

Other Financial Instruments. On June 21, 2022, the Group invested £100,000,000 into a 12-month deposit with an F1+ rated U.K. financial institution. This short term bank deposit accrued interest at a rate of 2.35% and was classified as a financial asset measured at amortised cost. The investment was redeemed on June 21, 2023.
On March 24, 2023, the Group invested £150,000,000 into a 9-month short term deposit with an F1 rated financial institution.

These short term bank deposits accrue interest at 5.2%, 5.4% and 5.4% respectively and have been classified as financial assets measured at amortised cost.
The Group also has a number of other financial instruments which are not measured at fair value in the balance sheet consisting of trade receivables, trade and other payables, other loans and lease liabilities. For these instruments, the fair values are not materially different to their carrying amounts, since the interest receivable/payable is either close to current market rates or the instruments are short-term in nature.

Clawback Shares. As part of the Group's acquisition of Allcyte in 2021, additional equity securities with a total fair value of £8,074,000 were issued to shareholders of Allcyte who act in management positions of the company. These shares are subject to a clawback period of three years from the acquisition date whereby should said employees leave their positions within the Group within the clawback period the shares will be repurchased by the Group at their then nominal value. The fair value of these securities has been excluded from the purchase consideration in accordance with paragraph B55 of IFRS3 and will be expensed to profit or loss on a systematic basis over the period to which the clawback relates.
The total expense recognised within the share based payment charge during the year to December 31, 2023 in relation to these shares in the period is £2,027,000 (2022: £3,939,000) . This expense is included within research and development expenses.
Share Options. Share options are granted to employees and non-executive directors of the Group. These options typically vest in tranches over four years, with the only vesting condition relating to continued employment by the Group. Information with respect to share options for the year ended December 31, 2023 is as follows:

Share options outstanding as at December 31, 2023 had exercise prices in the range of £0.02 to £7.86 (December 31, 2022: £0.02 to £0.07). The weighted average contractual life for options outstanding as of December 31, 2023 was 7.8 years (December 31, 2022: 7.8 years).
The following information is relevant to the determination of the fair value of the options issued during the period. The Black-Scholes model has been used to calculate the fair value of options of the equity settled share based payments, with the following weighted average values:
Exercise price£0.0005
Expected life6.0 years
Expected volatility95.7 %
Risk-free rate3.12 %
Expected dividend rate£0.00
Fair value£4.22
The fair value of the underlying ordinary shares is equal to the closing share price at the grant date converted at the prevailing exchange rate at that date. The risk-free rate is determined by reference to the rate of interest obtainable from U.S. Government Bonds over a period commensurate with the expect term of the options. Expected volatility has been set with reference to the Group's own share price volatility over the period from the Company’s IPO to the award grant date and peer group analysis. The expected life of the options has been set equal to the mid-point between the vesting date and the expiry date of the award in question.
Performance Share Options. Performance share options are granted to certain executive officers of the group on an annual basis, and contain market based performance conditions relating to total shareholder return as well as a continued employment vesting requirement. These awards vest in tranches over three years. Information with respect to performance share options for the year ended December 31, 2023 is as follows:

The fair value of the underlying ordinary shares is equal to closing share price at the grant date converted at the prevailing exchange rate at that date. The risk-free rate is determined by reference to the rate of interest obtainable from U.S. Government Bonds over a period commensurate with the expect term of the options. Expected volatility has been derived as the weighted average volatility of comparator companies who have been listed for a period commensurate with the expected term prior to the grant date, and the expected life of the options has been set equal to the mid-point between the vesting date and the expiry date of the award in question.
Performance Share Units. Performance share units are granted to certain executive officers of the group on an annual basis, and contain market based performance conditions relating to total shareholder return as well as a continued employment vesting requirement. These awards vest in tranches over three years.
Information with respect to performance share units for the year ended December 31, 2023 is as follows:

PSUs held as at December 31, 2023488,833 

The weighted average grant date fair value per unit of the PSUs granted in the year to December 31, 2023 was £4.10. The weighted average remaining contractual life of the awards granted was 9.0 years as at December 31, 2023.
A Monte Carlo model has been used to calculate the fair value of the performance share units as at the grant date, with the same model inputs as detailed for the performance share options above.
Restricted Share Units. The Group operates a RSU scheme, whereby certain employees and directors receive restricted stock units held over Ordinary shares in the Company. These units are non-transferable and subject to forfeiture for periods prescribed by the Company. These awards are valued at the market value of the underlying shares at the date of grant and are subsequently amortised over the periods during which the restrictions lapse, typically four years. The awards expire on the cessation of the participant’s employment with the Group.
Details of the RSUs in existence during the year to December 31, 2023 are as follows:
Number of RSUs

Gates Foundation Private Placement Commitment. Concurrent with the Company’s IPO on October 5, 2021, the Company completed a private placement to the Gates Foundation for the sale of 1,590,909 ADSs at the initial offering price of $22.00 per ADS, for gross proceeds of approximately $35,000,000 (£25,743,000). Under the terms of the Company’s agreement with the Gates Foundation, the Group is committed to spending $70,000,000 over a four-year period to the research, discovery, and development of small molecule anti-infective therapeutics for future pandemic preparedness, with a specific focus on developing therapeutics that can be applied against multiple species of coronaviridae, influenza, and paramyxoviridae (the “Pandemic Preparedness Program”). The Group had incurred £9,697,000 relating to the Pandemic Preparedness Program as at December 31, 2023 (2022: £6,459,000), with a total outstanding commitment of £41,789,000 (2022: £45,027,000).
In the event that the Group is in breach of certain terms within the agreement, the Gates Foundation has the right to sell, or require the Group to buy-back any shareholdings in the Group held by the Foundation at the higher of the public offering price and the market value of the shares at the date of default. Should such a breach occur or should the Company enter bankruptcy the Gates Foundation also has the exclusive right to utilise an exclusive global license granted as part of the agreement in relation to any IP generated by the Group pertaining to the Pandemic Preparedness Program for the benefit of people in certain developing countries. The default conditions are within the control of the Group and the license in question cannot be utilised unless such a default occurs or the Group enters bankruptcy. As such no fair value has been assigned to this license.

Exhibit 2.4
DESCRIPTION OF SHARE CAPITAL AND ARTICLES OF ASSOCIATION
Set forth below is a summary of certain information concerning the share capital of Exscientia plc (the “company”, “we”, “our” or “us”) as well as a description of certain provisions of our articles of association and relevant provisions of the Companies Act, together with a summary of certain differences in corporate law in the United Kingdom and Delaware. The summary below contains only material information concerning our share capital and corporate status and does not purport to be complete and is qualified in its entirety by reference to our articles of association as currently in effect and applicable English law, a copy of which is filed as an exhibit to the Annual Report on Form 20-F. Further, please note that holders of ADSs will not be treated as one of our shareholders and will not have any shareholder rights.
General
We are a public limited company, originally incorporated pursuant to the laws of England and Wales on June 29, 2021 as a private limited company named Exscientia Holdings Limited, with nominal assets and liabilities for the purpose of becoming the ultimate holding company for Exscientia AI Limited (formerly Exscientia Limited) and consummating a corporate reorganization prior to our initial public offering. Exscientia AI Limited was incorporated under the laws of Scotland in July 2012. On August 18, 2021 we changed our name to Exscientia Limited and Exscientia Limited changed its name to Exscientia AI Limited. On September 22, 2021, we were re-registered as a public limited company with the name Exscientia plc.

Our registered office in the United Kingdom is located at The Schrödinger Building, Oxford Science Park, Oxford OX4 4GE, United Kingdom, and the telephone number of our registered office is +44 (0)1865 818941.

Issued Share Capital
As of December 31, 2023, we had 125,702,396 ordinary shares outstanding, with a nominal value of £0.0005 per ordinary share. With the exception of 26,888 ordinary shares, each issued ordinary share is fully paid.

Ordinary Shares
The following summarizes the rights of holders of our ordinary shares:
a.each holder of our ordinary shares is entitled to one vote per ordinary share on all matters to be voted on by shareholders generally;
b.the holders of our ordinary shares shall be entitled to receive notice of, attend, speak and vote at our general meetings; and
c.the holders of our ordinary shares are entitled to receive such dividends as are recommended by our directors and declared by our shareholders.
See also “— Articles of Association” below.

RSUs, PSUs and Options
As of December 31, 2023, there were 1,019,186 RSUs and 488,833 PSUs outstanding, in addition to options to purchase 11,407,662 ordinary shares outstanding with a weighted average exercise price of £0.07 per ordinary share.

Register of Members
We are required by the Companies Act to keep a register of our shareholders. Under the laws of England and Wales, the ordinary shares are deemed to be issued when the name of the shareholder is entered in our register of members. The register of members therefore is prima facie evidence of the identity of our shareholders, and the shares that they hold. The register of members generally provides limited, or no, information regarding the ultimate beneficial owners of our ordinary shares. Our register of members is maintained by our registrar, Computershare Investor Services plc.

Holders of our ADSs are not treated as one of our shareholders and their names are therefore not entered in our register of members. The depositary, the custodian or their nominees are the holder of the ordinary shares underlying our ADSs. Holders of our ADSs have a right to receive the ordinary shares underlying their ADSs.

Under the Companies Act, we must enter an allotment of shares in our register of members as soon as practicable and in any event within two months of the allotment. We also are required by the Companies Act to register a transfer of shares (or give the transferee notice of and reasons for refusal) as soon as practicable and in any event within two months of receiving notice of the transfer.

We, any of our shareholders or any other affected person, may apply to the court for rectification of the register of members if:
a.the name of any person, without sufficient cause, is wrongly entered in or omitted from our register of members; or



b.there is a default or unnecessary delay in entering on the register the fact of any person having ceased to be a member or on which we have a lien, provided that such refusal does not prevent dealings in the shares taking place on an open and proper basis.

Registration Rights
We and certain holders of our ordinary shares have entered into a registration rights agreement that provides the following registration rights:
a.Demand Registration on Form F-1: Each holder shall be entitled to demand registrations on Form F-1, provided that these demand registration rights may only be exercised by holders who hold, in the aggregate, not less than 50% of the aggregate number of shares then outstanding and held by all holders who are party to the agreement, and provided further that the we shall not be required to effect a demand registration statement after we have effected two demand registration statements, and such registration statements have been declared or ordered effective.
b.Demand Registration on Form F-3: Each holder shall be entitled to unlimited demand registrations on Form F-3, if we are eligible to register shares on Form F-3, provided that these demand registration rights may only be exercised by holders who hold, in the aggregate, not less than 10% of the aggregate number of shares then outstanding and held by all holders who are party to the agreement. These demand registration rights may not be exercised more than twice in any twelve-month period.
c.Piggyback Registration: Each holder shall be entitled to piggyback registration rights, subject, in the case of an underwritten offering, to customary reductions by the underwriter, provided that the aggregate number of securities of the holders included in the registration may not be reduced to less than 30% of the total number of securities registered.
d.Expenses: We will pay all registration expenses relating to the exercise of the registration rights above, including the reasonable fees and expenses of legal counsel to the participating holders up to a maximum of $60,000 in the aggregate per registration.

Preemptive Rights
The laws of England and Wales generally provide shareholders with preemptive rights when new shares or rights to subscribe for, or convert securities into, new shares are issued for cash; however, it is possible for the articles of association, or shareholders at a general meeting representing at least 75% of our ordinary shares present (in person or by proxy) and voting at that general meeting, to disapply these preemptive rights. Such a disapplication of preemptive rights may be for a maximum period of up to five years from the date of adoption of the articles of association, if the disapplication is contained in the articles of association, or from the date of the shareholder resolution, if the disapplication is by shareholder resolution. In either case, this disapplication would need to be renewed by our shareholders upon its expiration (i.e., at least every five years).

On September 15, 2021, our shareholders authorized our board of directors to disapply preemptive rights on the allotment of equity securities (within the meaning of the Companies Act) for cash for a period of five years up to an aggregate nominal amount of £200,000. This disapplication (to the extent unutilized) remains effective until September 15, 2026.

Articles of Association
The following is a summary of certain key provisions of our articles of association, which were adopted by a special resolution of our shareholders passed in September 2021. Please note that this is only a summary and is not intended to be exhaustive.

The articles of association contain, among other things, provisions to the following effect:

Objects
The objects of the company are unrestricted.

Share Rights
Subject to the Companies Act and any rights attaching to shares already in issue, our shares may be issued with or have attached to them such rights and restrictions as we may by ordinary resolution of the shareholders determine or, in the absence of any such ordinary resolution or so far as the resolution does not make specific provision, as our board of directors may determine.

Voting Rights
Subject to any rights or restrictions attached to any shares from time to time, the general voting rights attaching to shares are as follows:
a.any resolution put to the vote of a general meeting must be decided exclusively on a poll; on a poll, every shareholder who is present in person or by proxy or corporate representative shall have one vote for each



share of which they are the holder. A shareholder entitled to more than one vote need not, if they vote, use all their votes or cast all the votes in the same way; and
b.if two or more persons are joint holders of a share, then in voting on any question the vote of the senior who tenders a vote, whether in person or by proxy, shall be accepted to the exclusion of the votes of the other joint holders. For this purpose, seniority shall be determined by the order in which the names of the holders stand in the share register.

Restrictions on Voting
No shareholder shall be entitled to vote at any general meeting or at any separate class meeting in respect of any share held by him unless all calls or other sums payable by him in respect of that share have been paid.

The board of directors may from time to time make calls upon the shareholders in respect of any money unpaid on their shares and each shareholder shall (subject to at least 14 clear days’ notice specifying the time or times and place of payment) pay at the time or times so specified the amount called on their shares.

Dividends
We may, subject to the provisions of the Companies Act and the articles of association, by ordinary resolution of shareholders declare dividends out of profits available for distribution in accordance with the respective rights of shareholders, but no such dividend shall exceed the amount recommended by the board of directors.

The board of directors may from time to time pay shareholders such interim dividends as appears to the board to be justified by the profits available for distribution (including any dividends at a fixed rate). If the share capital is divided into different classes, the board of directors may pay interim dividends on shares which confer deferred or non-preferred rights with regard to dividend as well as on shares which confer preferential rights with regard to dividend, but no interim dividend shall be paid on shares carrying deferred or non-preferred rights if, at the time of payment, any preferential dividend is in arrears.

The board of directors may deduct from any dividend or other money payable to any person on or in respect of a share all such sums as may be due from such shareholder to the company on account of calls or otherwise in relation to the shares of the company. Sums so deducted can be used to pay amounts owing to the company in respect of the shares.

Subject to any special rights attaching to or the terms of issue of any share, no dividend or other monies payable by us on or in respect of any share shall bear interest against us. Any dividend unclaimed after a period of 12 years from the date such dividend became due for payment shall (if the board of directors so resolves) be forfeited and shall cease to remain owing by the company.

Dividends may be declared or paid in any currency and the board may decide the rate of exchange for any currency conversions that may be required, and how any costs involved are to be met.

The board of directors may, by ordinary resolution of the company, direct (or in the case of an interim dividend may without the authority of an ordinary resolution direct) that payment of any dividend declared may be satisfied wholly or partly by the distribution of assets, and in particular of paid up shares or debentures of any other company, or in any one or more of such ways.

Change of Control
There is no specific provision in our articles of association that would have the effect of delaying, deferring or preventing a change of control.

Distributions on Winding Up
On a winding up, the liquidator may, with the sanction of a special resolution of shareholders and any other sanction required by law, divide among the shareholders in specie the whole or any part of the assets of the company and may, for that purpose, value any assets and determine how the division shall be carried out as between the shareholders or different classes of shareholders. The liquidator may, with the like sanction, vest the whole or any part of the assets in trustees upon such trusts for the benefit of the shareholders as he may with the like sanction determine, but no shareholder shall be compelled to accept any assets upon which there is a liability.

Variation of Rights
All or any of the rights and restrictions attached to any class of shares issued may be varied or abrogated with the consent in writing of the holders of not less than three-fourths in nominal value of the issued shares of that class (excluding any shares held as treasury shares) or by special resolution passed at a separate general meeting of the holders of such shares, subject to the Companies Act and the terms of their issue. The Companies Act provides a



right to object to the variation of the share capital by the shareholders who did not vote in favour of the variation. Should the holders of an aggregate of not less than 15% of the issued shares of the class in question apply to the court to have the variation cancelled, the variation shall have no effect unless and until it is confirmed by the court.

Alteration to Share Capital
We may, by ordinary resolution of shareholders, consolidate all or any of our share capital into shares of larger amount than our existing shares, or sub-divide our shares or any of them into shares of a smaller amount. We may, by special resolution of shareholders, confirmed by the court, reduce our share capital or any capital redemption reserve or any share premium account in any manner authorised by the Companies Act. We may redeem or purchase all or any of our shares as described in “— Other English Law Considerations — Purchase of Own Shares”.

Allotment of Shares and Preemptive Rights
Subject to the Companies Act and to any rights attached to existing shares, any share may be issued with or have attached to it such rights and restrictions as we may by ordinary resolution determine, or if no ordinary resolution has been passed or so far as the resolution does not make specific provision, as our board of directors may determine (including shares which are to be redeemed, or are liable to be redeemed at our option or the holder of such shares).

In accordance with section 551 of the Companies Act, the board of directors may be generally and unconditionally authorised to exercise for each prescribed period of up to five years all the powers of the company to allot shares or grant rights to subscribe for or to convert any security into shares up to an aggregate nominal amount equal to the amount stated in the relevant ordinary resolution authorizing such allotment.

On September 15, 2021, our shareholders granted our board of directors the authority to allot shares or grant rights to subscribe for, or to convert any security into, shares for a period of five years up to an aggregate nominal amount of £200,000. This authority (to the extent unutilized) remains effective until September 15, 2026.

In certain circumstances, our shareholders may have statutory preemptive rights under the Companies Act in respect of the allotment of new shares as described in “— Preemptive Rights” and “— Differences in Corporate Law — Preemptive Rights” in this document.

Transfer of Shares
Any shareholder holding shares in certificated form may transfer all or any of his shares by an instrument of transfer in any usual form or in any other manner which is permitted by the Companies Act and approved by the board. Any written instrument of transfer shall be signed by or on behalf of the transferor and (in the case of a share which is not fully paid up) the transferee.

All transfers of uncertificated shares shall be made in accordance with and subject to the provisions of the Uncertificated Securities Regulations 2001 and the facilities and requirements of its relevant system. The Uncertificated Securities Regulations 2001 permit shares to be issued and held in uncertificated form and transferred by means of a computer-based system.

The board of directors may, in its absolute discretion, decline to register any transfer of any share in certificated form unless:
a.it is for a share which is fully paid up;
b.it is for a share upon which the company has no lien;
c.it is only for one class of share;
d.it is in favour of a single transferee or no more than four joint transferees;
e.it is duly stamped or is duly certificated or otherwise shown to the satisfaction of the board to be exempt from stamp duty (if this is required); and
f.it is delivered for registration to our registered office (or such other place as the board may determine), accompanied (except in the case of a transfer by a person to whom the company is not required by law to issue a certificate and to whom a certificate has not been issued or in the case of a renunciation) by the certificate for the shares to which it relates and such other evidence as the board may reasonably require to prove the title of the transferor (or person renouncing) and the due execution of the transfer or renunciation by him or, if the transfer or renunciation is executed by some other person on his behalf, the authority of that person to do so.

The board of directors may decline to register a transfer of uncertificated shares in any circumstances that are allowed or required by the Uncertificated Securities Regulations 2001 and the requirements of its relevant system.
If the board of directors declines to register a transfer it shall, as soon as practicable and in any event within two months after the date on which the transfer is lodged, send to the transferee notice of the refusal, together with reasons for the refusal or, in the case of uncertified shares, notify such persons as may be required by the Uncertified Securities Regulations 2001 and the requirements of the relevant system concerned.




Our board of directors shall not refuse to register any transfer of partly paid shares in respect of which ADSs are admitted to Nasdaq on the grounds that they are partly paid shares in circumstances where such refusal would prevent dealings in such shares from taking place on an open and proper basis.

Annual General Meetings
In accordance with the Companies Act, we are required in each year to hold an annual general meeting in addition to any other general meetings in that year and to specify the meeting as such in the notice convening it. The annual general meeting shall be convened whenever and wherever the board sees fit, subject to the requirements of the Companies Act, as described in “— Differences in Corporate Law — Annual General Meeting” and “— Differences in Corporate Law — Notice of General Meetings” in this document.

Notice of General Meetings
The arrangements for the calling of general meetings are described in “— Differences in Corporate Law — Notice of General Meetings” in this document.

Quorum of General Meetings

No business shall be transacted at any general meeting unless a quorum is present. At least two shareholders present in person or by proxy and entitled to vote shall be a quorum for all purposes.

Class Meetings
The provisions in our articles of association relating to general meetings apply to every separate general meeting of the holders of a class of shares except that:
a.the quorum for such class meeting shall be two holders in person or by proxy representing not less than one-third in nominal value of the issued shares of the class (excluding any shares held in treasury); and
b.if at any adjourned meeting of such holders a quorum is not present at the meeting, one holder of shares of the class present in person or by proxy at an adjourned meeting constitutes a quorum.

Number of Directors
We may not have less than two directors or more than fifteen directors on the board of directors. We may, by ordinary resolution of the shareholders, vary the minimum and/or maximum number of directors from time to time.

Appointment of Directors, Classification and Reappointment of Directors
Subject to our articles of association and the Companies Act, the company may by ordinary resolution appoint a person who is willing to act as a director and the board of directors shall have power at any time to appoint any person who is willing to act as a director, in both cases either to fill a vacancy or as an addition to the existing board of directors, provided the total number of directors shall not exceed the maximum number of fifteen.

Our articles of association provide that our board of directors is divided into three classes, each of which will consist, as nearly as possible, of one-third of the total number of directors constituting our entire board and which will serve staggered three-year terms. At each annual general meeting, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual general meeting following election. Directors of the class retiring at the annual general meeting shall be eligible for re-appointment by ordinary resolution at such annual general meeting.

Directors’ Interests
The directors may authorise, to the fullest extent permitted by law, any matter or situation proposed to them which would otherwise result in a director infringing his duty to avoid a situation in which he has, or can have, a direct or indirect interest that conflicts, or possibly may conflict, with our interests. A director shall not, save as otherwise agreed by him, be accountable to us for any remuneration, profit or other benefit which he derives from any matter authorised by the directors or by the shareholders in general meeting and no contract shall be liable to be avoided on any such grounds.

Subject to the requirements under sections 175,177 and 182 of the Companies Act, a director who is any way, whether directly or indirectly, interested in a proposed or existing transaction or arrangement with us shall declare the nature of his interest at a meeting of the directors.

A director shall not vote or be counted in the quorum in respect of any transactions or arrangement with the company in which he has an interest and which may reasonably be regarded as likely to give rise to a conflict of interest. A director shall be entitled to vote (and be counted in the quorum) in respect of any resolution concerning any of the following matters:



a.the giving of any guarantee, security or indemnity in respect of money lent or obligations incurred by him or by any other person at the request of or for the benefit of our company or any of our subsidiary undertakings;
b.the giving of any guarantee, security or indemnity in respect of a debt or obligation of our company or any of our subsidiary undertakings for which he himself has assumed responsibility in whole or in part under a guarantee or indemnity or by the giving of security;
c.any proposal or contract relating to an offer of securities of or by our company or any of our subsidiary undertakings in which offer he is or may be entitled to participate as a holder of securities or in the underwriting or sub-underwriting of which he is to participate;
d.any arrangement involving any other company if the director (together with any person connected with him) has an interest of any kind in that company (including an interest by holding any position in that company or by being a member of that company), unless he is to his knowledge (either directly or indirectly) the holder of or beneficially interested in one per cent or more of any class of the equity share capital of that company (calculated exclusive of any shares of that class in that company held as treasury shares) or of the voting rights available to members of that company;
e.any arrangement for the benefit of employees of our company or any of our subsidiary undertakings which only gives him benefits which are also generally given to employees to whom the arrangement relates;
f.any contract relating to insurance which we can buy or renew for the benefit of the directors or a group of people which includes directors; and
g.a contract relating to a pension, superannuation or similar scheme or a retirement, death, disability benefits scheme or employees’ share scheme which gives the director benefits which are also generally given to the employees to whom the scheme relates.

If a question arises at a meeting of the board or of a committee of the board as to the right of a director to vote or be counted in the quorum, and such question is not resolved by his voluntarily agreeing to abstain from voting or not to be counted in the quorum, the question shall be determined by the chairman of the meeting and his ruling in relation to any director other than himself shall be final and conclusive except in a case where the nature or extent of the interest of the director concerned has not been fairly disclosed. If the question arises about the chairman of the meeting, the question must be directed to the directors. The chairman cannot vote on the question but can be counted in the quorum. The directors’ resolution about the chairman is final and conclusive, unless the nature and extent of the chairman’s interests have not been fairly disclosed to the directors.

Directors’ Fees and Remuneration
Each of the directors shall be paid a fee at such rate as may from time to time be determined by the board (or for the avoidance of doubt any duly authorised committee of the board) provided that the aggregate of all such fees payable to the directors shall not exceed $2,500,000 per annum, or such higher amount as may from time to time be determined by ordinary resolution of the shareholders.

Each director may be paid his reasonable travelling, hotel and other expenses of attending and returning from meetings of the board or committees of the board or general meetings or separate meetings of the holders of any class of shares or of debentures and shall be paid all expenses properly incurred by him in the conduct of the Company’s business.

Any director who performs or renders any special duties or services outside his ordinary duties as a director and not in his capacity as a holder of employment or executive officer may be paid such reasonable extra remuneration by way of salary, commissions, participation in profits or otherwise as the directors may determine.

Borrowing Powers
Subject to our articles of association and the Companies Act, the board of directors may exercise all the powers to borrow money, provide any indemnity or guarantee and to mortgage or charge our undertaking, property and assets (present or future) and uncalled capital or any part thereof, to create and issue debentures and other securities and to give security, whether outright or as collateral security for any debt, liability or obligation of us or of any third party.

Indemnity
Every current or former director or other officer of our group may be indemnified against all costs, charges, expenses, losses and liabilities sustained or incurred by them in connection with that director’s or officer’s duties or powers in relation to the company or other members of our group.

Other Relevant English Law Considerations

Mandatory Bid
We believe that, at the date of this document, our place of central management and control is not in the United Kingdom (or the Channel Islands or the Isle of Man) for the purposes of the jurisdictional criteria of the Takeover



Code. Accordingly, we believe that we are not currently subject to the Takeover Code and, as a result, our shareholders are not currently entitled to benefit from certain takeover offer protections provided under the Takeover Code, including the rules regarding mandatory takeover bids (a summary of which is set out below). In the event that this changes, or if the interpretation or application of the Takeover Code by the Takeover Panel changes (including changes to the way in which the Takeover Panel assesses the application of the Takeover Code to English companies whose shares are listed outside the United Kingdom), the Takeover Code may apply to us in the future.

Under the Takeover Code, where:
a.any person, together with persons acting in concert with him, acquires, whether by a series of transactions over a period of time or not, an interest in shares which (taken together with shares in which he is already interested, and in which persons acting in concert with him are interested) carry 30% or more of the voting rights of a company; or
b.any person who, together with persons acting in concert with him, is interested in shares which in the aggregate carry not less than 30% of the voting rights of a company but does not hold shares carrying more than 50% of such voting rights and such person, or any person acting in concert with him, acquires an interest in any other shares which increases the percentage of shares carrying voting rights in which he is interested,

such person shall, except in limited circumstances, be obliged to extend offers, on the basis set out in Rules 9.3, 9.4 and 9.5 of the Takeover Code, to the holders of any class of equity share capital, whether voting or non-voting, and also to the holders of any other class of transferable securities carrying voting rights. Offers for different classes of equity share capital must be comparable; the Takeover Panel should be consulted in advance in such cases.

An offer under Rule 9 of the Takeover Code must be in cash or be accompanied by a cash alternative at not less than the highest price paid for any interest in the shares by the person required to make an offer or any person acting in concert with him during the 12 months prior to the announcement of the offer.

Under the Takeover Code, a “concert party” arises where persons acting together pursuant to an agreement or understanding (whether formal or informal and whether or not in writing) actively cooperate, through the acquisition by them of an interest in shares in a company, to obtain or consolidate control of the company. “Control” means holding, or aggregate holdings, of an interest in shares carrying 30% or more of the voting rights of the company, irrespective of whether the holding or holdings give de facto control.

Mandatory Purchases and Acquisitions
Pursuant to Sections 979 to 991 of the Companies Act, where a takeover offer has been made for us and the offeror has acquired or unconditionally contracted to acquire not less than 90% in value of the shares to which the offer relates and not less than 90% of the voting rights carried by those shares, the offeror may give notice to the holder of any shares to which the offer relates which the offeror has not acquired or unconditionally contracted to acquire that he wishes to acquire, and is entitled to so acquire, those shares on the same terms as the general offer. The offeror would do so by sending a notice to the outstanding minority shareholders telling them that it will compulsorily acquire their shares.

Such notice must be sent within three months of the last day on which the offer can be accepted in the prescribed manner or if earlier, and the offer is not one to which section 943(1) of the Companies Act applies, within the period of six months beginning with the date of the offer. The squeeze out of the minority shareholders can be completed at the end of six weeks from the date the notice has been given, subject to the minority shareholders failing to successfully lodge an application to the court to prevent such squeeze out any time prior to the end of those six weeks following which the offeror can execute a transfer of the outstanding shares in its favour and pay the consideration to us, which would hold the consideration on trust for the outstanding minority shareholders. The consideration offered to the outstanding minority shareholders whose shares are compulsorily acquired under the Companies Act must, in general, be the same as the consideration that was available under the takeover offer.

Sell Out
The Companies Act also gives our minority shareholders a right to be bought out in certain circumstances by an offeror who has made a takeover offer for all of our shares. The holder of shares to which the offer relates, and who has not otherwise accepted the offer, may require the offeror to acquire his shares if, prior to the expiry of the acceptance period for such offer, (1) the offeror has acquired or unconditionally agreed to acquire not less than 90% in value of the voting shares and (2) not less than 90% of the voting rights carried by those shares. The offeror may impose a time limit on the rights of minority shareholders to be bought out that is not less than three months after the end of the acceptance period. If a shareholder exercises his rights to be bought out, the offeror is required to acquire those shares on the terms of this offer or on such other terms as may be agreed.




Disclosure of Interest in Shares
Pursuant to Part 22 of the Companies Act and our articles of association, we are empowered by notice in writing to any person whom we know or have reasonable cause to believe to be interested in our shares, or at any time during the three years immediately preceding the date on which the notice is issued has been so interested, within a reasonable time to disclose to us particulars of that person’s interest and (so far as is within his knowledge) particulars of any other interest that subsists or subsisted in those shares.

Under our articles of association, if a person defaults in supplying us with the required particulars in relation to the shares in question, or default shares, within the prescribed period, the following sanctions shall apply unless the board determines otherwise:
a.in respect of the default shares, the relevant shareholder shall not be entitled to be present at or to vote (either in person or by representative or proxy) at any general meeting or to exercise any other right conferred by a shareholding in relation to general meetings; and
b.where the default shares represent at least 0.25% in nominal value of the issued shares of their class, (a) any dividend or other money payable in respect of the default shares shall be retained by us without liability to pay interest and/or (b) no transfers by the relevant shareholder of any default shares may be registered (unless the shareholder himself is not in default and the shareholder proves to the satisfaction of the directors that no person in default of supplying such information is interested in any of the shares that are the subject of the transfer.

Purchase of Own Shares
Under the laws of England and Wales, a public limited company may only purchase its own shares out of the distributable profits of the company or the proceeds of a fresh issue of shares made for the purpose of financing the purchase, subject to complying with procedural requirements under the Companies Act and provided that they are not restricted from doing so by their articles of association. A public limited company may not purchase its own shares if, as a result of the purchase, there would no longer be any issued shares of the company other than redeemable shares or shares held as treasury shares. Shares must be fully paid to be repurchased.

Any such purchase will be either a “market purchase” or “off market purchase”, each as defined in the Companies Act. A “market purchase” is a purchase made on a “recognised investment exchange” (other than an overseas exchange) as defined in the U.K. Financial Services and Markets Act 2000, as amended, or FSMA. An “off market purchase” is a purchase that is not made on a “recognised investment exchange”. Both “market purchases” and “off market purchases” require prior shareholder approval by way of an ordinary resolution. In the case of an “off market purchase”, a company’s shareholders, other than the shareholders from whom the company is purchasing shares, must approve the terms of the contract to purchase shares and in the case of a “market purchase”, the shareholders must approve the maximum number of shares that can be purchased and the maximum and minimum prices to be paid by the company. Both resolutions authorizing “market purchases” and “off-market purchases” must specify a date, not later than five years after the passing of the resolution, on which the authority to purchase is to expire.

A share buy-back by a company of its shares will give rise to U.K. stamp duty reserve tax and stamp duty at the rate of 0.5% of the amount or value of the consideration payable by the company (rounded up to the next £5.00), and such stamp duty reserve tax or stamp duty will be paid by the company. The charge to U.K. stamp duty reserve tax will be cancelled or, if already paid, repaid (generally with interest), where a transfer instrument for U.K. stamp duty purposes has been duly stamped within six years of the charge arising (either by paying the U.K. stamp duty or by claiming an appropriate relief) or if the instrument is otherwise exempt from U.K. stamp duty.

Nasdaq is an “overseas exchange” for the purposes of the Companies Act and does not fall within the definition of a “recognised investment exchange” for the purposes of FSMA and any purchase made by us would need to comply with the procedural requirements under the Companies Act that regulate “off market purchases”.

Our shareholders have approved the form of a share repurchase contract in respect of a proposed “off market purchase” by us of certain shares in our share capital held by the Gates Foundation, with such contract to be entered into by us and the Gates Foundation on a future date. This is to enable us to comply with our obligations in the event we are required to repurchase for cash all of the Gates Foundation’s shares pursuant to our global access agreement with the Gates Foundation.

At our annual general meeting held on May 18, 2022, our shareholders approved the forms of share repurchase contracts and counterparties with whom such contracts may be entered into for the purpose of making repurchases of our ordinary shares (including ordinary shares represented by ADSs). These approvals are valid for five years. To date, we have not entered into any share repurchase contract with a counterparty.




Our shareholders also approved a contract for the purchase by the company of its deferred shares of £0.01 each at the annual general meeting held on May 18, 2022. On June 27, 2022, we repurchased the 324,121 deferred shares outstanding in exchange for an aggregate consideration of £1.00 and cancelled the deferred shares on that date.

Our articles of association do not have conditions governing changes to our capital which are more stringent than those required by law.

Distributions and Dividends
Under the Companies Act, before a company can lawfully make a distribution or dividend, it must ensure that it has sufficient distributable reserves (on a non-consolidated basis). The basic rule is that a company’s profits available for the purpose of making a distribution are its accumulated, realised profits, so far as not previously utilised by distribution or capitalisation, less its accumulated, realised losses, so far as not previously written off in a reduction or reorganisation of capital duly made. The requirement to have sufficient distributable reserves before a distribution or dividend can be paid applies to us and to each of our subsidiaries that has been incorporated under the laws of England and Wales.

It is not sufficient that we, as a public limited company, have made a distributable profit for the purpose of making a distribution. An additional capital maintenance requirement is imposed on us to ensure that the net worth of the company is at least equal to the amount of its capital. A public limited company can only make a distribution:
a.if, at the time that the distribution is made, the amount of its net assets (that is, the total excess of assets over liabilities) is not less than the total of its called-up share capital and undistributable reserves; and
b.if, and to the extent that, the distribution itself, at the time that it is made, does not reduce the amount of the net assets to less than that total.

Shareholder Rights
Certain rights granted under the Companies Act, including the right to requisition a general meeting or require a resolution to be put to shareholders at the annual general meeting, are only available to our shareholders. For English law purposes, our shareholders are the persons who are registered as the owners of the legal title to the shares and whose names are recorded in our share register. If a person who holds their ADSs in DTC wishes to exercise certain of the rights granted under the Companies Act, they may be required to first take steps to withdraw their ADSs from the settlement system operated by DTC and become the registered holder of the shares in our share register. A withdrawal of shares from DTC may have tax implications.

Exchange Controls
There are no governmental laws, decrees, regulations or other legislation in the United Kingdom that may affect the import or export of capital, including the availability of cash and cash equivalents for use by us, or that may affect the remittance of dividends, interest or other payments by us to non-resident holders of our ordinary shares or ADSs representing our ordinary shares, other than withholding tax requirements. There is no limitation imposed by the laws of England and Wales or in the articles of association on the right of non-residents to hold or vote shares.

Differences in Corporate Law
The applicable provisions of the Companies Act differ from laws applicable to U.S. corporations and their shareholders. Set forth below is a summary of certain differences between the provisions of the Companies Act applicable to us and the General Corporation Law of the State of Delaware relating to shareholders’ rights and protections. This summary is not intended to be a complete discussion of the respective rights and it is qualified in its entirety by reference to Delaware law and the laws of England and Wales.



England and WalesDelaware
Number of DirectorsUnder the Companies Act, a public limited company must have at least two directors and the number of directors may be fixed by or in the manner provided in a company’s articles of association.Under Delaware law, a corporation must have at least one director and the number of directors shall be fixed by or in the manner provided in the bylaws.
Removal of DirectorsUnder the Companies Act, shareholders may remove a director without cause by an ordinary resolution (which is passed by a simple majority of those voting in person or by proxy at a general meeting) irrespective of any provisions of any service contract the director has with the company, provided 28 clear days’ notice of the resolution has been given to the company and its shareholders. On receipt of notice of an intended resolution to remove a director, the company must forthwith send a copy of the notice to the director concerned. Certain other procedural requirements under the. Companies Act must also be followed such as allowing the director to make representations against his or her removal either at the meeting or in writing.Under Delaware law, any director or the entire board of directors may be removed, with or without cause, by the holders of a majority of the shares then entitled to vote at an election of directors, except (a) unless the certificate of incorporation provides otherwise, in the case of a corporation whose board of directors is classified, shareholders may effect such removal only for cause or (b) in the case of a corporation having cumulative voting, if less than the entire board of directors is to be removed, no director may be removed without cause if the votes cast against his removal would be sufficient to elect him if then cumulatively voted at an election of the entire board of directors, or, if there are classes of directors, at an election of the class of directors of which he is a part.
Vacancies on the Board of DirectorsUnder the laws of England and Wales, the procedure by which directors, other than a company’s initial directors, are appointed is generally set out in a company’s articles of association, provided that where two or more persons are appointed as directors of a public limited company by resolution of the shareholders, resolutions appointing each director must be voted on individually unless a resolution has first been unanimously passed confirming that a single resolution appointing two or more directors may be tabled at that meeting.Under Delaware law, vacancies and newly created directorships may be filled by a majority of the directors then in office (even though less than a quorum) or by a sole remaining director unless (a) otherwise provided in the certificate of incorporation or by-laws of the corporation or (b) the certificate of incorporation directs that a particular class of stock is to elect such director, in which case a majority of the other directors elected by such class, or a sole remaining director elected by such class, will fill such vacancy.





Annual General MeetingUnder the Companies Act, a public limited company must hold an annual general meeting in each six-month period following its annual accounting reference date.Under Delaware law, the annual meeting of stockholders shall be held at such place, on such date and at such time as may be designated from time to time by the board of directors or as provided in the certificate of incorporation or by the bylaws.
General Meeting
Under the Companies Act, a general meeting of the shareholders of a public limited company may be called by the directors.

Shareholders holding at least 5% of the paid-up capital of the company carrying voting rights at general meetings (excluding any paid up capital held as treasury shares) can require the directors to call a general meeting and, if the directors fail to do so within a certain period, may themselves (or any of them representing more than one half of the total voting rights of all of them) convene a general meeting.
Under Delaware law, special meetings of the stockholders may be called by the board of directors or by such person or persons as may be authorised by the certificate of incorporation or by the bylaws.
Notice of General MeetingsSubject to a company’s articles of association providing for a longer period, under the Companies Act, 21 clear days’ notice must be given for an annual general meeting and any resolutions to be proposed at the meeting. Subject to a company’s articles of association providing for a longer period, at least 14 clear days’ notice is required for any other general meeting. In addition, certain matters, such as the removal of directors or auditors, require special notice, which is 28 clear days’ notice. The shareholders of a company (that is not a “traded company”, as such term is defined in Part 13 of the Companies Act) may in all cases consent to a shorter notice period, the proportion of shareholders’ consent required being 100% of those entitled to attend and vote in the case of an annual general meeting and, in the case of any other general meeting, a majority in number of the members having a right to attend and vote at the meeting, being a majority who together hold not less than 95% in nominal value of the shares giving a right to attend and vote at the meeting.Under Delaware law, unless otherwise provided in the certificate of incorporation or bylaws, written notice of any meeting of the stockholders must be given to each stockholder entitled to vote at the meeting not less than 10 nor more than 60 days before the date of the meeting and shall specify the place, date, hour and purpose or purposes of the meeting.





QuorumSubject to the provisions of a company’s articles of association, the Companies Act provides that two shareholders present at a meeting (in person, by proxy or authorised representative under the Companies Act) shall constitute a quorum for companies with more than one shareholder.The certificate of incorporation or bylaws may specify the number of shares, the holders of which shall be present or represented by proxy at any meeting to constitute a quorum, but in no event shall a quorum consist of less than one third of the shares entitled to vote at the meeting. In the absence of such specification in the certificate of incorporation or bylaws, a majority of the shares entitled to vote, present in person or represented by proxy, shall constitute a quorum at a meeting of stockholders.
ProxyUnder the Companies Act, at any meeting of shareholders, a shareholder may designate another person to attend, speak and vote at the meeting on their behalf by proxy.Under Delaware law, at any meeting of stockholders, a stockholder may designate another person to act for such stockholder by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period. A director of a Delaware corporation may not issue a proxy representing the director’s voting rights as a director.
Preemptive RightsUnder the Companies Act, “equity securities”, being (1) shares in the company other than shares that, with respect to dividends and capital, carry a right to participate only up to a specified amount in a distribution, referred to as “ordinary shares” or (2) rights to subscribe for, or to convert securities into, ordinary shares, proposed to be allotted for cash must be offered first to the existing equity shareholders in the company in proportion to the respective nominal value of their holdings, unless an exception applies or a special resolution to the contrary has been passed by shareholders in a general meeting or the articles of association provide otherwise in each case in accordance with the provisions of the Companies Act.Under Delaware law, shareholders have no preemptive rights to subscribe to additional issues of stock or to any security convertible into such stock unless, and except to the extent that, such rights are expressly provided for in the certificate of incorporation.





Authority to AllotUnder the Companies Act, the directors of a company must not allot shares or grant rights to subscribe for or to convert any security into shares unless an exception applies or an ordinary resolution to the contrary has been passed by shareholders in a general meeting or the articles of association provide otherwise in each case in accordance with the provisions of the Companies Act.Under Delaware law, if the corporation’s charter or certificate of incorporation so provides, the board of directors has the power to authorise the issuance of stock. It may authorise capital stock to be issued for consideration consisting of cash, any tangible or intangible property or any benefit to the corporation or any combination thereof. It may determine the amount of such consideration by approving a formula. In the absence of actual fraud in the transaction, the judgement of the directors as to the value of such consideration is conclusive.
Liability of Directors and Officers
Under the Companies Act, any provision, whether contained in a company’s articles of association or any contract or otherwise, that purports to exempt a director of a company, to any extent, from any liability that would otherwise attach to him in connection with any negligence, default, breach of duty or breach of trust in relation to the company is void.
Any provision by which a company directly or indirectly provides an indemnity, to any extent, for a director of the company or of an associated company against any liability attaching to him in connection with any negligence, default, breach of duty or breach of trust in relation to the company of which he is a director is also void except as permitted by the Companies Act, which provides exceptions for the company to (a) purchase and maintain insurance against such liability; (b) provide a “qualifying third party indemnity” (being an indemnity against liability incurred by the director to a person other than the company or an associated company or criminal proceedings in which he is convicted); and (c) provide a “qualifying pension scheme indemnity” (being an indemnity against liability incurred in connection with our activities as trustee of an occupational pension plan).
Under Delaware law, a corporation’s certificate of incorporation may include a provision eliminating or limiting the personal liability of a director to the corporation and its stockholders for damages arising from a breach of fiduciary duty as a director. However, no provision can limit the liability of a director for:
 
•  any breach of the director’s duty of loyalty to the corporation or its stockholders;
 
•  acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;
 
•  intentional or negligent payment of unlawful dividends or stock purchases or redemptions; or
 
•  any transaction from which the director derives an improper personal benefit.





Voting Rights
Under the laws of England and Wales, unless a poll is demanded by the shareholders of a company or is required by the chairman of the meeting or our articles of association, shareholders shall vote on all resolutions on a show of hands. Under the Companies Act, a poll may be demanded by (a) not fewer than five shareholders having the right to vote on the resolution; (b) any shareholder(s) representing not less than 10% of the total voting rights of all the shareholders having the right to vote on the resolution (excluding any voting rights attaching to treasury shares); or (c) any shareholder(s) holding shares in the company conferring a right to vote on the resolution (excluding any voting rights attaching to treasury shares) being shares on which an aggregate sum has been paid up equal to not less than 10% of the total sum paid up on all the shares conferring that right. A company’s articles of association may provide more extensive rights for shareholders to call a poll.
Under the laws of England and Wales, an ordinary resolution is passed on a show of hands if it is approved by a simple majority (more than 50%) of the votes cast by shareholders present (in person or by proxy) and entitled to vote. If a poll is demanded, an ordinary resolution is passed if it is approved by holders representing a simple majority of the total voting rights of shareholders present, in person or by proxy, who, being entitled to vote, vote on the resolution. Special resolutions require the affirmative vote of not less than 75% of the votes cast by shareholders present, in person or by proxy, at the meeting. If a poll is demanded, a special resolution is passed if it is approved by holders representing not less than 75% of the total voting rights of shareholders in person or by proxy who, being entitled to vote, vote on the resolution.
Delaware law provides that, unless otherwise provided in the certificate of incorporation, each stockholder is entitled to one vote for each share of capital stock held by such stockholder.


Shareholder Vote on Certain Transactions
The Companies Act provides for schemes of arrangement, which are arrangements or compromises between a company and any class of shareholders or creditors and used in certain types of reconstructions, amalgamations, capital reorganisations or takeovers. These arrangements require:
a.the approval at a shareholders’ or creditors’ meeting convened by order of the court, of a majority in number of shareholders or creditors representing 75% in value of the capital held by, or debt owed to, the class of shareholders or creditors, or class thereof present and voting, either in person or by proxy; and
b.the approval of the court.
Generally, under Delaware law, unless the certificate of incorporation provides for the vote of a larger portion of the stock, completion of a merger, consolidation, sale, lease or exchange of all or substantially all of a corporation’s assets or dissolution requires:
a. the approval of the board of directors; and
b. approval by the vote of the holders of a majority of the outstanding stock or, if the certificate of incorporation provides for more or less than one vote per share, a majority of the votes of the outstanding stock of a corporation entitled




Standard of Conduct for Directors
Under the laws of England and Wales, a director owes various statutory and fiduciary duties to the company, including:

a.to act in the way he considers, in good faith, would be most likely to promote the success of the company for the benefit of its members as a whole;
b.to avoid a situation in which he has, or can have, a direct or indirect interest that conflicts, or possibly conflicts, with the interests of the company;
c.to act in accordance with our constitution and only exercise his powers for the purposes for which they are conferred;
d.to exercise independent judgement;
e.to exercise reasonable care, skill and diligence;
f.not to accept benefits from a third party conferred by reason of his being a director or doing, or not doing, anything as a director; and
g.to declare any interest that he has, whether directly or indirectly, in a proposed or existing transaction or arrangement with the company.
Delaware law does not contain specific provisions setting forth the standard of conduct of a director. The scope of the fiduciary duties of directors is generally determined by the courts of the State of Delaware. In general, directors have a duty to act without self-interest, on a well-informed basis and in a manner they reasonably believe to be in the best interest of the stockholders.
Directors of a Delaware corporation owe fiduciary duties of care and loyalty to the corporation and to its shareholders. The duty of care generally requires that a director act in good faith, with the care that an ordinarily prudent person would exercise under similar circumstances. Under this duty, a director must inform himself of all material information reasonably available regarding a significant transaction. The duty of loyalty requires that a director act in a manner he reasonably believes to be in the best interests of the corporation. He must not use his corporate position for personal gain or advantage. In general, but subject to certain exceptions, actions of a director are presumed to have been made on an informed basis, in good faith and in the honest belief that the action taken was in the best interests of the corporation. However, this presumption may be rebutted by evidence of a breach of one of the fiduciary duties. Delaware courts have also imposed a heightened standard of conduct upon directors of a Delaware corporation who take any action designed to defeat a threatened change in control of the corporation.





In addition, under Delaware law, when the board of directors of a Delaware corporation approves the sale or break-up of a corporation, the board of directors may, in certain circumstances, have a duty to obtain the highest value reasonably available to the shareholders.
Stockholder SuitsUnder the laws of England and Wales, generally, the company, rather than its shareholders, is the proper claimant in an action in respect of a wrong done to the company or where there is an irregularity in the company’s internal management. Notwithstanding this general position, the Companies Act provides that (1) a court may allow a shareholder to bring a derivative claim (that is, an action in respect of and on behalf of the company) in respect of a cause of action arising from a director’s negligence, default, breach of duty or breach of trust and (2) a shareholder may bring a claim for a court order where our affairs have been or are being conducted in a manner that is unfairly prejudicial to some of its shareholders.
Under Delaware law, a stockholder may initiate a derivative action to enforce a right of a corporation if the corporation fails to enforce the right itself. The complaint must:
a. state that the plaintiff was a stockholder at the time of the transaction of which the plaintiff complains or that the plaintiffs shares thereafter devolved on the plaintiff by operation of law; and
b. allege with particularity the efforts made by the plaintiff to obtain the action the plaintiff desires from the directors and the reasons for the plaintiff’s failure to obtain the action; or
c. state the reasons for not making the effort.

Additionally, the plaintiff must remain a stockholder through the duration of the derivative suit. The action will not be dismissed or compromised without the approval of the Delaware Court of Chancery.


Securities Exchange Listing
Our ADSs are listed on the Nasdaq Global Select Market under the symbol “EXAI”.

Registrar of Shares; Depositary for ADSs
Our share register is maintained by Computershare Investor Services plc. The share register reflects only registered holders of our ordinary shares. Our ordinary shares are not listed for trading on any securities exchange and we do not plan to list our ordinary shares on any securities exchange.

Holders of ADSs representing our ordinary shares are not treated as our shareholders and their names will therefore not be entered in our share register. Citibank N.A. acts as the depositary for the ADSs representing our ordinary shares. The custodian for ordinary shares represented by ADSs is Citibank, N.A., London Branch. Holders of ADSs representing our ordinary shares have a right to receive the ordinary shares underlying such ADSs.


Exhibit 2.5
DESCRIPTION OF AMERICAN DEPOSITARY SHARES
Depositary

We have appointed Citibank, N.A., or Citibank, as the depositary for the ADSs pursuant to a deposit agreement, or the Deposit Agreement. Citibank’s depositary offices are located at 388 Greenwich Street, New York, New York 10013.

Provisions

ADSs represent ownership interests in securities that are on deposit with the depositary. ADSs may be represented by certificates that are commonly known as American Depositary Receipts, or ADRs. The depositary typically appoints a custodian to safekeep the securities on deposit. In this case, the custodian is Citibank, N.A., London Branch, located at 25 Canada Square, Canary Wharf, London, E14 5LB, United Kingdom.
The following is a summary of the material provisions of the Deposit Agreement. For more complete information, you should read the Deposit Agreement and Form of ADR. The Deposit Agreement has been filed with the Securities and Exchange Commission as an exhibit to the Annual Report on 20-F of which this Exhibit is a part.
Each ADS represents the right to receive, and to exercise the beneficial ownership interests in, one ordinary share that is on deposit with the depositary or custodian. An ADS also represents the right to receive, and to exercise the beneficial interests in, any other property received by the depositary or the custodian on behalf of the owner of the ADS but that has not been distributed to the owners of ADSs because of legal restrictions or practical considerations. We and the depositary may agree to change the ADS-to-share ratio by amending the Deposit Agreement. This amendment may give rise to, or change, the depositary fees payable by ADS owners. The custodian, the depositary and their respective nominees will hold all deposited property for the benefit of the holders and beneficial owners of ADSs. The deposited property does not constitute the proprietary assets of the depositary, the custodian or their nominees. Beneficial ownership in the deposited property will under the terms of the Deposit Agreement be vested in the beneficial owners of the ADSs. The depositary, the custodian and their respective nominees will be the record holders of the deposited property represented by the ADSs for the benefit of the holders and beneficial owners of the corresponding ADSs. A beneficial owner of ADSs may or may not be the holder of ADSs. Beneficial owners of ADSs will be able to receive, and to exercise beneficial ownership interests in, the deposited property only through the registered holders of the ADSs, the registered holders of the ADSs (on behalf of the applicable ADS owners) only through the depositary, and the depositary (on behalf of the owners of the corresponding ADSs) directly, or indirectly, through the custodian or their respective nominees, in each case upon the terms of the Deposit Agreement.
If you become an owner of ADSs, you will become a party to the Deposit Agreement and therefore will be bound to its terms and to the terms of any ADR that represents your ADSs. The deposit agreement and the ADR specify our rights and obligations as well as your rights and obligations as owner of ADSs and those of the depositary. As an ADS holder you appoint the depositary to act on your behalf in certain circumstances. The deposit agreement and the ADRs are governed by New York law. However, our obligations to the holders of ordinary shares will continue to be governed by the laws of England and Wales, which may be different from the laws in the United States.
In addition, applicable laws and regulations may require you to satisfy reporting requirements and obtain regulatory approvals in certain circumstances. You are solely responsible for complying with such reporting requirements and obtaining such approvals. None of the depositary, the custodian, us or any of their or our respective agents or affiliates shall be required to take any actions whatsoever on your behalf to satisfy such reporting requirements or obtain such regulatory approvals under applicable laws and regulations. You agree to comply with information requests from us pursuant to applicable laws, stock exchange rules and our articles of association. We may restrict transfers of ADSs and take other actions necessary to comply with any applicable ownership restrictions.
Holders will not be treated as one of our shareholders and will not have direct shareholder rights. The depositary will hold on the behalf of the holders the shareholder rights attached to the ordinary shares underlying the ADSs. Holders are able to exercise the shareholders rights for the ordinary shares represented by their ADSs through the depositary only to the extent contemplated in the Deposit Agreement. To exercise any shareholder rights not contemplated in the Deposit Agreement holders will need to arrange for the cancellation of their ADSs and become a direct shareholder.



The manner in which you own the ADSs (e.g., in a brokerage account versus as a registered holder, or as a holder of certificated versus uncertificated ADSs) may affect your rights and obligations, and the manner in which, and extent to which, the depositary’s services are made available to you.
Holders may hold your ADSs either by means of an ADR registered in your name, through a brokerage or safekeeping account, or through an account established by the depositary in your name reflecting the registration of uncertificated ADSs directly on the books of the depositary (commonly referred to as the direct registration system or DRS). The direct registration system reflects the uncertificated (book-entry) registration of ownership of ADSs by the depositary. Under the direct registration system, ownership of ADSs is evidenced by periodic statements issued by the depositary to the holders of the ADSs. The direct registration system includes automated transfers between the depositary and The Depository Trust Company, or DTC, the central book-entry clearing and settlement system for equity securities in the United States. If you decide to hold your ADSs through your brokerage or safekeeping account, you must rely on the procedures of your broker or bank to assert your rights as ADS owner. Banks and brokers typically hold securities such as the ADSs through clearing and settlement systems such as DTC. The procedures of such clearing and settlement systems may limit your ability to exercise your rights as an owner of ADSs. Please consult with your broker or bank if you have any questions concerning these limitations and procedures. All ADSs held through DTC will be registered in the name of a nominee of DTC. This summary description assumes you have opted to own the ADSs directly by means of an ADS registered in your name and, as such, we will refer to you as the “holder”. When we refer to “you”, we assume the reader owns ADSs and will own ADSs at the relevant time.
The registration of the ordinary shares in the name of the depositary or the custodian shall, to the maximum extent permitted by applicable law, vest in the depositary or the custodian the record ownership in the applicable ordinary shares with the beneficial ownership rights and interests in such ordinary shares being at all times vested with the beneficial owners of the ADSs representing the ordinary shares. The depositary or the custodian shall at all times be entitled to exercise the beneficial ownership rights in all deposited property, in each case only on behalf of the holders and beneficial owners of the ADSs representing the deposited property.
Dividends and Other Distributions
Holders generally have the right to receive the distributions we make on the securities deposited with the custodian. Your receipt of these distributions may be limited, however, by practical considerations and legal limitations. Holders of ADSs will receive such distributions under the terms of the Deposit Agreement in proportion to the number of ADSs held as of the specified record date, after deduction the applicable fees, taxes and expenses.
Distributions of Cash
Whenever we make a cash distribution for the securities on deposit with the custodian, we will deposit the funds with the custodian. Upon receipt of confirmation of the deposit of the requisite funds, the depositary will arrange for the funds received in a currency other than U.S. dollars to be converted into U.S. dollars and for the distribution of the U.S. dollars to the holders, subject to the laws and regulations of England and Wales. The conversion into U.S. dollars will take place only if practicable and if the U.S. dollars are transferable to the United States. The depositary will apply the same method for distributing the proceeds of the sale of any property (such as undistributed rights) held by the custodian in respect of securities on deposit.
The distribution of cash will be made net of the fees, expenses, taxes and governmental charges payable by holders under the terms of the Deposit Agreement. The depositary will hold any cash amounts it is unable to distribute in a non-interest bearing account for the benefit of the applicable holders and beneficial owners of ADSs until the distribution can be effected or the funds that the depositary holds must be escheated as unclaimed property in accordance with the laws of the relevant states of the United States.
Distributions of Shares
Whenever we make a free distribution of ordinary shares for the securities on deposit with the custodian, we will deposit the applicable number of ordinary shares with the custodian. Upon receipt of confirmation of such deposit, the depositary will either distribute to holders new ADSs representing the ordinary shares deposited or modify the ADS-to-ordinary shares ratio, in which case each ADS you hold will represent rights and interests in the additional ordinary shares so deposited. Only whole new ADSs will be distributed. Fractional entitlements will be sold, and the proceeds of such sale will be distributed as in the case of a cash distribution.
The distribution of new ADSs or the modification of the ADS-to-ordinary shares ratio upon a distribution of ordinary shares will be made net of the fees, expenses, taxes and governmental charges payable by holders under



the terms of the Deposit Agreement. To pay such taxes or governmental charges, the depositary may sell all or a portion of the new ordinary shares so distributed.
No such distribution of new ADSs will be made if it would violate a law (e.g., the U.S. securities laws) or if it is not operationally practicable. If the depositary does not distribute new ADSs as described above, it may sell the ordinary shares received upon the terms described in the Deposit Agreement and will distribute the proceeds of the sale as in the case of a distribution of cash.
Distributions of Rights
Whenever we intend to distribute rights to purchase additional ordinary shares, we will give prior notice to the depositary and we will assist the depositary in determining whether it is lawful and reasonably practicable to distribute rights to purchase additional ADSs to holders.
The depositary will establish procedures to distribute rights to purchase additional ADSs to holders and to enable such holders to exercise such rights if it is lawful and reasonably practicable to make the rights available to holders of ADSs, and if we provide all the documentation contemplated in the Deposit Agreement (such as opinions to address the lawfulness of the transaction). You may have to pay fees, expenses, taxes and other governmental charges to subscribe for the new ADSs upon the exercise of your rights. The depositary is not obligated to establish procedures to facilitate the distribution and exercise by holders of rights to purchase new ordinary shares other than in the form of ADSs.
The depositary will not distribute the rights to you if:
we do not timely request that the rights be distributed to you or we request that the rights not be distributed to you; or
we fail to deliver satisfactory documents to the depositary; or
it is not reasonably practicable to distribute the rights.
The depositary will sell the rights that are not exercised or not distributed if such sale is lawful and reasonably practicable. The proceeds of such sale will be distributed to holders as in the case of a cash distribution. If the depositary is unable to sell the rights, it will allow the rights to lapse.
Elective Distributions
Whenever we intend to distribute a dividend payable at the election of shareholders either in cash or in additional shares, we will give prior notice thereof to the depositary and will indicate whether we wish the elective distribution to be made available to you. In such case, we will assist the depositary in determining whether such distribution is lawful and reasonably practicable.
The depositary will make the election available to you only if it is reasonably practicable and if we have provided all the documentation contemplated in the Deposit Agreement. In such case, the depositary will establish procedures to enable you to elect to receive either cash or additional ADSs, in each case as described in the Deposit Agreement.
If the election is not made available to you, you will receive either cash or additional ADSs, depending on what a shareholder in England and Wales would receive upon failing to make an election, as more fully described in the Deposit Agreement.
Other Distributions
Whenever we intend to distribute property other than cash, ordinary shares or rights to purchase additional ordinary shares, we will notify the depositary in advance and will indicate whether we wish such distribution to be made to you. If so, we will assist the depositary in determining whether such distribution to holders is lawful and reasonably practicable.
If it is reasonably practicable to distribute such property to you and if we provide all the documentation contemplated in the Deposit Agreement, the depositary will distribute the property to the holders in a manner it deems practicable.



The distribution will be made net of fees, expenses, taxes and governmental charges payable by holders under the terms of the Deposit Agreement. To pay such taxes and governmental charges, the depositary may sell all or a portion of the property received.
The depositary will not distribute the property to you and will sell the property if:
we do not request that the property be distributed to you or if we ask that the property not be distributed to you; or
we do not deliver satisfactory documents to the depositary; or
the depositary determines that all or a portion of the distribution to you is not reasonably practicable.
The proceeds of such a sale will be distributed to holders as in the case of a cash distribution.
Redemption
Whenever we decide to redeem any of the securities on deposit with the custodian, we will notify the depositary in advance. If it is practicable and if we provide all the documentation contemplated in the Deposit Agreement, the depositary will provide notice of the redemption to the holders.
The custodian will be instructed to surrender the shares being redeemed against payment of the applicable redemption price. The depositary will convert the redemption funds received in a currency other than U.S. dollars into U.S. dollars upon the terms of the Deposit Agreement and will establish procedures to enable holders to receive the net proceeds from the redemption upon surrender of their ADSs to the depositary. You may have to pay fees, expenses, taxes and other governmental charges upon the redemption of your ADSs. If less than all ADSs are being redeemed, the ADSs to be retired will be selected by lot or on a pro rata basis, as the depositary may determine.
Changes Affecting Ordinary Shares
The ordinary shares held on deposit for your ADSs may change from time to time. For example, there may be a change in nominal value, sub-division, cancellation, consolidation or any other reclassification of such ordinary shares or a recapitalisation, reorganisation, merger, consolidation or sale of assets of our company.
If any such change were to occur, your ADSs would, to the extent permitted by law and the Deposit Agreement, represent the right to receive the property received or exchanged in respect of the ordinary shares held on deposit. The depositary may in such circumstances deliver new ADSs to you, amend the Deposit Agreement, the ADRs and the applicable registration statement(s) on Form F-6, call for the exchange of your existing ADSs for new ADSs and take any other actions that are appropriate to reflect as to the ADSs the change affecting the ordinary shares. If the depositary may not lawfully distribute such property to you, the depositary may sell such property and distribute the net proceeds to you as in the case of a cash distribution.
Transfer, Combination and Split Up of ADRs
Holders are entitled to transfer, combine or split up your ADRs and the ADSs evidenced thereby. For transfers of ADRs, you will have to surrender the ADRs to be transferred to the depositary and also must:
ensure that the surrendered ADR is properly endorsed or otherwise in proper form for transfer;
provide such proof of identity and genuineness of signatures, and of such other matters contemplated in the Deposit Agreement, as the depositary deems appropriate;
comply with applicable laws and regulations, including regulations imposed by us and the depositary consistent with the Deposit Agreement, the ADR and applicable law;
provide any transfer stamps required by the State of New York or the United States; and
pay all applicable fees, charges, expenses, taxes and other government charges payable by ADR holders pursuant to the terms of the Deposit Agreement, upon the transfer of ADRs.



To have your ADRs either combined or split up, you must surrender the ADRs in question to the depositary with your request to have them combined or split up, and you must pay all applicable fees, charges and expenses payable by ADR holders, pursuant to the terms of the Deposit Agreement, upon a combination or split up of ADRs.
Withdrawal of Ordinary Shares Upon Cancellation of ADSs
Holders are entitled to present your ADSs to the depositary for cancellation and then receive the corresponding number of underlying ordinary shares at the custodian’s offices. Your ability to withdraw the ordinary shares held in respect of the ADSs may be limited by legal considerations under the laws of the United States and England and Wales applicable at the time of withdrawal. To withdraw the ordinary shares represented by your ADSs, you will be required to pay to the depositary the fees for cancellation of ADSs and any charges and taxes payable upon the transfer of the ordinary shares. You assume the risk for delivery of all funds and securities upon withdrawal. Once cancelled, the ADSs will not have any rights under the Deposit Agreement.
If you hold ADSs registered in your name, the depositary may ask you to provide proof of identity and genuineness of any signature and such other documents as the depositary may deem appropriate before it will cancel your ADSs. The withdrawal of the ordinary shares represented by your ADSs may be delayed until the depositary receives satisfactory evidence of compliance with all applicable laws and regulations. Please keep in mind that the depositary will only accept ADSs for cancellation that represent a whole number of securities on deposit.
You will have the right to withdraw the securities represented by your ADSs at any time except as a result of:
temporary delays that may arise because (1) the transfer books for the ordinary shares or ADSs are closed, or (2) ordinary shares are immobilised on account of a shareholders’ meeting or a payment of dividends;
obligations to pay fees, taxes and similar charges; or
restrictions imposed because of laws or regulations applicable to ADSs or the withdrawal of securities on deposit.
The deposit agreement may not be modified to impair your right to withdraw the securities represented by your ADSs except to comply with mandatory provisions of law.
Voting Rights
Holders generally have the right under the Deposit Agreement to instruct the depositary to exercise the voting rights for the ordinary shares represented by your ADSs. The voting rights of holders of ordinary shares are described in the section titled “Description of Share Capital and Articles of Association” in this prospectus.
At our request, the depositary will distribute to you any notice of shareholders’ meeting received from us together with information explaining how to instruct the depositary to exercise the voting rights of the securities represented by ADSs. In lieu of distributing such materials, the depositary may distribute to holders of ADSs instructions on how to retrieve such materials upon request.
If the depositary timely receives voting instructions from a holder of ADSs, it will endeavour to vote the securities (in person or by proxy) represented by the holder’s ADSs as follows:
In the event of voting by show of hands, the depositary will vote (or cause the custodian to vote) all ordinary shares held on deposit at that time in accordance with the voting instructions received from a majority of holders of ADSs who provide timely voting instructions.
In the event of voting by poll, the depositary will vote (or cause the custodian to vote) the ordinary shares held on deposit in accordance with the voting instructions received from the holders of ADSs.
Note that our articles of association currently provide for all resolutions to be decided as a poll, not a show of hands. The depositary will not join in demanding a vote by poll.
Securities for which no voting instructions have been received will not be voted (except as otherwise contemplated in the Deposit Agreement). Please note that the ability of the depositary to carry out voting



instructions may be limited by practical and legal limitations and the terms of the securities on deposit. We cannot assure you that you will receive voting materials in time to enable you to return voting instructions to the depositary in a timely manner.
Fees and Charges
As an ADS holder, you will be required to pay the following fees under the terms of the Deposit Agreement:
ServiceFees
Issuance of ADSs (e.g., an issuance of ADS upon a deposit of ordinary shares, upon a change in the ADS(s)-to-ordinary share(s) ratio, or for any other reason), excluding ADS issuances as a result of distributions of ordinary shares)
Up to U.S. 5¢ per ADS issued
Cancellation of ADSs (e.g., a cancellation of ADSs for delivery of deposited property, upon a change in the ADS(s)-to-ordinary share(s) ratio, or for any other reason)
Up to U.S. 5¢ per ADS cancelled
Distribution of cash dividends or other cash distributions (e.g., upon a sale of rights and other entitlements)

Up to U.S. 5¢ per ADS held
ADS Services
Up to U.S. 5¢ per ADS held on the applicable record date(s) established by the depositary    
Registration of ADS transfers (e.g., upon a registration of the transfer of registered ownership of ADSs, upon a transfer of ADSs into DTC and vice versa, or for any other reason)
Up to U.S. 5¢ per ADS (or fraction thereof) transferred
Conversion of ADSs of one series for ADSs of another series (e.g., upon conversion of Partial Entitlement ADSs for Full Entitlement ADSs, or upon conversion of Restricted ADSs (each as defined in the Deposit Agreement) into freely transferable ADSs, and vice versa).
Up to U.S. 5¢ per ADS (or fraction thereof) converted
As an ADS holder you will also be responsible to pay certain charges such as:
taxes (including applicable interest and penalties) and other governmental charges;



the registration fees as may from time to time be in effect for the registration of ordinary shares on the share register and applicable to transfers of ordinary shares to or from the name of the custodian, the depositary or any nominees upon the making of deposits and withdrawals, respectively;
certain cable, telex and facsimile transmission and delivery expenses;
the fees, expenses, spreads, taxes and other charges of the depositary and/or service providers (which may be a division, branch or affiliate of the depositary) in the conversion of foreign currency;
the reasonable and customary out-of-pocket expenses incurred by the depositary in connection with compliance with exchange control regulations and other regulatory requirements applicable to ordinary shares, ADSs and ADRs; and
the fees, charges, costs and expenses incurred by the depositary, the custodian, or any nominee in connection with the ADR program.
ADS fees and charges for (i) the issuance of ADSs, and (ii) the cancellation of ADSs are charged to the person for whom the ADSs are issued (in the case of ADS issuances) and to the person for whom ADSs are cancelled (in the case of ADS cancellations). In the case of ADSs issued by the depositary into DTC, the ADS issuance and cancellation fees and charges may be deducted from distributions made through DTC, and may be charged to the DTC participant(s) receiving the ADSs being issued or the DTC participant(s) holding the ADSs being cancelled, as the case may be, on behalf of the beneficial owner(s) and will be charged by the DTC participant(s) to the account of the applicable beneficial owner(s) in accordance with the procedures and practices of the DTC participants as in effect at the time. ADS fees and charges in respect of distributions and the ADS service fee are charged to the holders as of the applicable ADS record date. In the case of distributions of cash, the amount of the applicable ADS fees and charges is deducted from the funds being distributed. In the case of (i) distributions other than cash and (ii) the ADS service fee, holders as of the ADS record date will be invoiced for the amount of the ADS fees and charges and such ADS fees and charges may be deducted from distributions made to holders of ADSs. For ADSs held through DTC, the ADS fees and charges for distributions other than cash and the ADS service fee may be deducted from distributions made through DTC, and may be charged to the DTC participants in accordance with the procedures and practices prescribed by DTC and the DTC participants in turn charge the amount of such ADS fees and charges to the beneficial owners for whom they hold ADSs. In the case of (i) registration of ADS transfers, the ADS transfer fee will be payable by the ADS Holder whose ADSs are being transferred or by the person to whom the ADSs are transferred, and (ii) conversion of ADSs of one series for ADSs of another series, the ADS conversion fee will be payable by the Holder whose ADSs are converted or by the person to whom the converted ADSs are delivered.
In the event of refusal to pay the depositary fees, the depositary may, under the terms of the Deposit Agreement, refuse the requested service until payment is received or may set off the amount of the depositary fees from any distribution to be made to the ADS holder. Certain depositary fees and charges (such as the ADS services fee) may become payable shortly after the closing of the ADS offering. Note that the fees and charges you may be required to pay may vary over time and may be changed by us and by the depositary. You will receive prior notice of such changes. The depositary may reimburse us for certain expenses incurred by us in respect of the ADR program, by making available a portion of the ADS fees charged in respect of the ADR program or otherwise, upon such terms and conditions as we and the depositary agree from time to time.
Amendments and Termination
We may agree with the depositary to modify the Deposit Agreement at any time without your consent. We undertake to give holders of ADSs 30 days’ prior notice of any modifications that would materially prejudice any of their substantial rights under the Deposit Agreement. We will not consider to be materially prejudicial to your substantial rights any modifications or supplements that are reasonably necessary for the ADSs to be registered under the Securities Act or to be eligible for book-entry settlement, in each case without imposing or increasing the fees and charges you are required to pay. In addition, we may not be able to provide you with prior notice of any modifications or supplements that are required to accommodate compliance with applicable provisions of law.
You will be bound by the modifications to the Deposit Agreement if you continue to hold your ADSs after the modifications to the Deposit Agreement become effective. The deposit agreement cannot be amended to prevent you from withdrawing the ordinary shares represented by your ADSs (except as permitted by law).
We have the right to direct the depositary to terminate the Deposit Agreement subject to certain conditions. Similarly, the depositary may in certain circumstances on its own initiative terminate the Deposit Agreement. In



either case, the depositary must give notice to the holders at least 30 days before termination. Until termination, your rights under the Deposit Agreement will be unaffected.
After termination, the depositary will continue to collect distributions received (but will not distribute any such property until you request the cancellation of your ADSs) and may sell the securities held on deposit. After the sale, the depositary will hold the proceeds from such sale and any other funds then held for the holders of ADSs in a non-interest-bearing account. At that point, the depositary will have no further obligations to ADS holders other than to account for the funds then held for the holders of ADSs still outstanding (after deduction of applicable fees, taxes and expenses).
In connection with the termination of the Deposit Agreement, the depositary may, but shall not be obligated to, independently and without the need for any action by us, make available to holders of ADSs a means to withdraw the ordinary shares and other deposited securities represented by their ADSs and to direct the deposit of such ordinary shares and other deposited securities into an unsponsored American depositary shares programme established by the depositary, upon such terms and conditions as the depositary may deem reasonably appropriate, subject however, in each case, to satisfaction of the applicable registration requirements by the unsponsored American depositary shares programme under the Securities Act, and to receipt by the depositary of payment of the applicable fees and charges of, and reimbursement of the applicable expenses incurred by, the depositary.
Books of Depositary
The depositary maintains ADS holder records at its depositary office. You may inspect such records at such office during regular business hours but solely for the purpose of communicating with other holders in the interest of business matters relating to the ADSs and the Deposit Agreement.
The depositary maintains in New York facilities to record and process the issuance, cancellation, combination, split-up and transfer of ADSs. These facilities may be closed from time to time, to the extent not prohibited by law.
Limitations on Obligations and Liabilities
The deposit agreement limits our obligations and the depositary’s obligations to you. Please note the following:
We and the depositary are obligated only to take the actions specifically stated in the Deposit Agreement without negligence or bad faith.
The depositary disclaims any liability for any failure to carry out voting instructions, for any manner in which a vote is cast or for the effect of any vote, provided it acts in good faith and in accordance with the terms of the Deposit Agreement.
The depositary disclaims any liability for any failure to determine the lawfulness or practicality of any action, for the content of any document forwarded to you on our behalf or for the accuracy of any translation of such a document, for the investment risks associated with investing in ordinary shares, for the validity or worth of the ordinary shares, for any tax consequences that result from the ownership of ADSs, for the credit-worthiness of any third party, for allowing any rights to lapse under the terms of the Deposit Agreement, for the timeliness of any of our notices or for our failure to give notice.
We and the depositary will not be obligated to perform any act that is inconsistent with the terms of the Deposit Agreement.
We and the depositary disclaim any liability if we or the depositary are prevented or forbidden from or subject to any civil or criminal penalty or restraint on account of, or delayed in, doing or performing any act or thing required by the terms of the Deposit Agreement, by reason of any provision, present or future of any law or regulation, or by reason of present or future provision of any provision of our Articles of Association, or any provision of or governing the securities on deposit, or by reason of any act of God or war or other circumstances beyond our control.
We and the depositary disclaim any liability by reason of any exercise of, or failure to exercise, any discretion provided for in the Deposit Agreement or in our Articles of Association or in any provisions of or governing the securities on deposit.



We and the depositary further disclaim any liability for any action or inaction in reliance on the advice or information received from legal counsel, accountants, any person presenting Shares for deposit, any holder of ADSs or authorised representatives thereof, or any other person believed by either of us in good faith to be competent to give such advice or information.
We and the depositary also disclaim liability for the inability by a holder to benefit from any distribution, offering, right or other benefit that is made available to holders of ordinary shares but is not, under the terms of the Deposit Agreement, made available to you.
We and the depositary may rely without any liability upon any written notice, request or other document believed to be genuine and to have been signed or presented by the proper parties.
We and the depositary also disclaim liability for any consequential or punitive damages for any breach of the terms of the Deposit Agreement.
No disclaimer of any Securities Act liability is intended by any provision of the Deposit Agreement.
Nothing in the Deposit Agreement gives rise to a partnership or joint venture, or establishes a fiduciary relationship, among us, the depositary and you as ADS holder.
Nothing in the Deposit Agreement precludes Citibank (or its affiliates) from engaging in transactions in which parties adverse to us or the ADS owners have interests, and nothing in the Deposit Agreement obligates Citibank to disclose those transactions, or any information obtained in the course of those transactions, to us or to the ADS owners, or to account for any payment received as part of those transactions.
As the above limitations relate to our obligations and the depositary’s obligations to you under the Deposit Agreement, we believe that, as a matter of construction of the clause, such limitations would likely to continue to apply to ADS holders who withdraw the ordinary shares from the ADS facility with respect to obligations or liabilities incurred under the Deposit Agreement before the cancellation of the ADSs and the withdrawal of the ordinary shares, and such limitations would most likely not apply to ADS holders who withdraw the ordinary shares from the ADS facility with respect to obligations or liabilities incurred after the cancellation of the ADSs and the withdrawal of the ordinary shares and not under the Deposit Agreement.
In any event, you will not be deemed, by agreeing to the terms of the Deposit Agreement, to have waived our or the depositary’s compliance with U.S. federal securities laws and the rules and regulations promulgated thereunder. In fact, you cannot waive our or the depositary’s compliance with U.S. federal securities laws and the rules and regulations promulgated thereunder
Taxes
Holders or Beneficial Owners of ADSs are responsible for the taxes and other governmental charges payable on the ADSs and the securities represented by the ADSs as provided for in the Deposit Agreement. We, the depositary and the custodian may deduct from any distribution the taxes and governmental charges payable by Holders and Beneficial Owners (as defined in the Deposit Agreement) of ADSs and may sell any and all property on deposit to pay the taxes and governmental charges payable by ADS holders. As a Holder or Beneficial Owner of ADSs, you will be liable for any deficiency if the sale proceeds do not cover the taxes that are due. Notwithstanding the foregoing, we expect to bear the cost of stamp duty or stamp duty reserve tax, if any, payable in respect of the issue of ordinary shares to the depositary in this offering.
The depositary may refuse to issue ADSs, to deliver, transfer, split and combine ADRs or to release securities on deposit until all taxes and charges are paid by the applicable Holder or Beneficial Owner (as defined in the Deposit Agreement) of ADSs. The depositary and the custodian may take reasonable administrative actions to obtain tax refunds and reduced tax withholding for any distributions on your behalf. However, you may be required to provide to the depositary and to the custodian proof of taxpayer status and residence and such other information as the depositary and the custodian may require to fulfil legal obligations. You are required to indemnify us, the depositary and the custodian for any claims with respect to taxes based on any tax benefit obtained for you.
Foreign Currency Conversion
The depositary will arrange for the conversion of all foreign currency received into U.S. dollars if such conversion is practical, and it will distribute the U.S. dollars in accordance with the terms of the Deposit Agreement.



You may have to pay fees and expenses incurred in converting foreign currency, such as fees and expenses incurred in complying with currency exchange controls and other governmental requirements.
If the conversion of foreign currency is not practical or lawful, or if any required approvals are denied or not obtainable at a reasonable cost or within a reasonable period, the depositary may take any of the following actions in its discretion:
Convert the foreign currency to the extent practical and lawful and distribute the U.S. dollars to the ADS holders for whom the conversion and distribution is lawful and practical.
Distribute the foreign currency to ADS holders for whom the distribution is lawful and practical.
Hold the foreign currency (without liability for interest) for the applicable ADS holders.
Governing Law / Waiver of Jury Trial
The deposit agreement and the ADRs and ADSs will be interpreted in accordance with the laws of the State of New York. The rights of holders of ordinary shares (including ordinary shares represented by ADSs) are governed by the laws of England and Wales.
AS A PARTY TO THE DEPOSIT AGREEMENT, YOU IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, YOUR RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF THE DEPOSIT AGREEMENT OR THE ADRs AGAINST US AND/OR THE DEPOSITARY.
The deposit agreement provides that, to the extent permitted by law, ADS holders waive the right to a jury trial of any claim they may have against us or the depositary arising out of or relating to our ordinary shares, the ADSs or the Deposit Agreement, including any claim under U.S. federal securities laws. If we or the depositary opposed a jury trial demand based on the waiver, the court would determine whether the waiver was enforceable in the facts and circumstances of that case in accordance with applicable case law. However, you will not be deemed, by agreeing to the terms of the Deposit Agreement, to have waived our or the depositary’s compliance with U.S. federal securities laws and the rules and regulations promulgated thereunder.

1.1.3Development Milestones. Sales Milestones. Commercial Milestones. Merck shall deliver written notice to Company upon achievement of each Development, Sales and Commercial Milestone Event, which notice shall be delivered (a) with respect to a Development Milestone and Sales Milestone within [***] days of such achievement, and (b) with respect to Commercial Milestone [***] for the Calendar Quarter in which such Milestone Event is first achieved. Following receipt of such written notice, Company shall promptly invoice Merck for the applicable Milestone payment.
1.1.4Milestones in General.
(a)One-time only. A Milestone shall be payable only once upon first occurrence [***]. For the avoidance of doubt, the total maximum amount in Discovery Milestones, Development Milestones and Sales Milestones payable under this Section 7.2 with respect to a Collaboration Target (exclusive of the bonus payment set forth in Section 7.2.2) shall not exceed [***], and the total maximum Commercial Milestones payable under this Section 7.2 with respect to a Product shall not exceed [***].
(b)Invoicing and Payment. Following receipt of the proper invoice issued by Company for the applicable Milestone payment, Merck will make such Milestone payment within [***] days after receipt of such invoice.

For that portion of Net Sales of Product that is greater than USD [***][***]%
21


1.1.2Net Sales Subject to Net Sales Payments. For purposes of determining whether a Net Sales Payment rate threshold or a Commercial Milestone has been attained, only Net Sales that are subject to a Net Sales Payment shall be included in the total amount of Net Sales and any net sales that are not subject to a Net Sales Payment shall be excluded. In addition, in no event shall the manufacture of a Product give rise to a Net Sales Payment obligation. For clarity, Merck’s obligation to pay Net Sales Payments to Company under this ARTICLE 7 is imposed only once with respect to the same unit of Product regardless of the number of Patent Rights pertaining thereto.
1.5Compulsory License. In the event that Company or Merck receives a request for a Compulsory License anywhere in the world, it shall promptly notify the other Party. If any Third Party obtains a Compulsory License in any country, then Company or Merck (whoever has first notice) shall promptly notify the other Party. Thereafter, as of the date the Third Party obtained such Compulsory License in such country, any Net Sales Payment rate payable under this Agreement to Company for Net Sales in such country cannot exceed [***] of any royalty rate paid by such Third Party. This shall apply mutatis mutandis if Merck grants a Sublicense to a Third Party in any country to avoid the imposition of such a Compulsory License.
1.6Reductions, Deductions and Reimbursements.
1.1.1Net Sales Payment on Know-How. Any Net Sales Payment rates under this Agreement applicable to the Net Sales of a Product in a country will be reduced by [***] during any period within the Net Sales Payment Term in which there is: (a) no Valid Claim in such country that Covers such Product in such country; and (b) no continuing regulatory, pediatric, orphan drug or data exclusivity.
1.1.2Generic Competition. In the event that in any country in the Territory during the Net Sales Payment Term for a Product, there are one (1) or more Generic Versions of such Product on the market in such country, then any Net Sales Payment rate for the applicable Product in the applicable country will be reduced by [***].
1.1.3Maximum Reduction. In no event shall the cumulative reduction of Net Sales Payment rates under Sections 7.6.1 and 7.6.2 reduce the Net Sales Payment payable to Company under Section 7.4 for any Product in any country during any Calendar Quarter below [***]. In the event that Merck is not able to deduct the full amount of the permitted deduction from the Net Sales Payment amounts due to Company due to the [***] maximum reduction, Company shall be entitled to deduct any undeducted excess amount from subsequent Net Sales Payment amounts owed to Company (subject always to Company receiving a minimum of [***] of the amount owed).
1.7Timing of Payment. Net Sales Payments payable under Section 7.4 shall be payable on actual Net Sales and shall accrue at the time the Product is delivered. Net Sales Payment obligations that have accrued during a particular [***] shall be paid, on a [***] basis, within [***] days after the end of each [***] during which the Net Sales Payment obligation accrued.
22


1.8Mode of Payment and Currency; Invoices.
7.7.1    Currency. All payments to Company hereunder shall be made by deposit of USD in the requisite amount to such bank account as Company may from time to time designate by written notice to Merck. With respect to sales not denominated in USD, Merck shall convert applicable sales in foreign currency into USD by using the then current and reasonable standard exchange rate methodology applied to its external reporting. Based on the resulting sales in USD, the then applicable Net Sales Payment amount shall be calculated. The Parties may vary the method of payment set forth herein at any time upon mutual written agreement, and any change shall be consistent with the local Applicable Law at the place of payment or remittance.
7.7.2.    Invoices. Invoices sent by Company to Merck shall include the purchase order number provided by Merck to Company. If Merck fails to provide such purchase order number to Company until the time of invoicing, Merck shall upon written request from Company provide such purchase order number without undue delay. Company shall address its invoices to:
[***]

1.9Net Sales Payment Reports and Records Retention. Within [***] days after the end of each [***] during which Product has been sold, Merck shall deliver to Company, together with the applicable Net Sales Payment due for such [***], a written report, on a Product-by-Product and a country-by-country basis, of Net Sales for such Calendar Quarter. Such report shall be deemed “Confidential Information” of Merck subject to the obligations of ARTICLE 9 of this Agreement. For [***] years after each sale of Product occurs, Merck shall, and shall ensure that its Affiliates and Sublicensees, keep complete and accurate records of such sale in sufficient detail to confirm the accuracy of the Net Sales Payment calculations hereunder.
1.10Legal Restrictions. If at any time legal restrictions prevent the remittance by Merck of all or any part of Net Sales Payments in any country, Merck shall have the right and option to make such payment by depositing the amount thereof in local currency to an account in the name of Company in a bank or other depository selected by Company in such country.
1.11Audits.
7.11.1    Audits Generally. During the Net Sales Payment Term and for [***] thereafter, and not more than [***], Merck shall permit, and shall cause its Affiliates or Sublicensees to permit, an independent certified public accounting firm of nationally recognized standing selected by Company, and reasonably acceptable to Merck or such Affiliate or Sublicensee, to have access to and to review, during normal business hours upon reasonable prior written notice, the applicable records of Merck and its Affiliates or Sublicensees to verify the accuracy of the Net Sales Payment reports and payments under this ARTICLE 7. Such review may cover those records for sales which Merck is required to maintain pursuant to Section 7.9. The accounting firm shall disclose to Company and Merck only whether the Net Sales Payment reports are correct or incorrect and the specific details concerning any discrepancies. No other information shall be provided to Company.
23


7.11.2    Audit-Based Reconciliation. If such accounting firm concludes that additional Net Sales Payment amounts were owed during such period, and Merck agrees with such calculation, Merck shall pay the additional undisputed Net Sales Payment amounts within [***] days after the date on which Company delivers to Merck such accounting firm’s written report. If such accounting firm concludes that an overpayment was made, such overpayment shall be fully creditable against amounts payable in subsequent payment periods or, at Merck’s request, shall be promptly reimbursed to Merck. If Merck disagrees with such calculation, it may retain its own independent certified public accounting firm of recognized standing and reasonably acceptable to Company, to conduct a review (“Second Audit”), and if such firm concurs with the other accounting firm, Merck shall make the required payment within [***] days after the date Merck receives the report of its accounting firm. If Merck’s accounting firm does not concur, Merck and Company shall meet and negotiate in good faith a resolution of the discrepancies between the two firms. Company shall pay for the cost of any audit, unless such audit is a Second Audit or Merck has underpaid Company by [***] or more, in which case Merck shall pay for the costs of audit.
7.11.3 Audit Confidentiality. Each Party shall treat all information that it receives under this Section 7.11 in accordance with the confidentiality provisions of ARTICLE 9, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with the other Party obligating such firm to retain all such financial information in confidence pursuant to such confidentiality agreement, except to the extent necessary for such Party to enforce its rights under this Agreement.
1.12Taxes.
1.1.1Tax Withholding. The amounts payable by one Party (the “Payer”) to the other Party (the “Payee”) pursuant to this Agreement (“Payments”) shall not be reduced on account of any Taxes unless required by Applicable Law. The Payee alone shall be responsible for paying any and all Taxes levied on account of, or measured in whole or in part by reference to, any Payments it receives. The Payer shall deduct or withhold from the Payments any Taxes that it is required by Applicable Law to deduct or withhold. Notwithstanding the foregoing, if the Payee is entitled under any applicable Tax treaty to a reduction of rate of, or the elimination of, or recovery of, applicable withholding Tax, it shall promptly deliver to the Payer or the appropriate Governmental Body the prescribed forms necessary to reduce the applicable rate of withholding or to relieve the Payer of its obligation to withhold Tax, and the Payer shall apply the reduced rate of withholding, or dispense with the withholding, as the case may be. If, in accordance with the foregoing, the Payer withholds any amount, it shall make timely payment to the proper Taxing authority of the withheld amount and send to the Payee reasonable proof of such payment within [***] days following that payment. For the avoidance of doubt, Payee shall on request of Payer refund to Payer any amounts received from Payer or its Affiliates under this Agreement, which should have been deducted or withheld under Applicable Law, but which were not deducted or withheld in full or at all; and Payor shall - following receipt of such refund - carry out, unless already completed, the payment of the Taxes to the proper Governmental Body.
1.1.2Value Added Tax. For indirect Tax (VAT, GST, sales tax and similar, collectively referred to as “VAT”) purposes aforesaid fees and expenses shall be understood as net amounts, i.e. statutory VAT is to be added, if applicable, either additionally invoiced or self-accounted by recipient of supply according to applicable VAT law. The invoicing party is obliged to issue an invoice for all payable amounts under this Agreement in accordance with applicable VAT law and irrespective of whether the sums may be netted for settlement purposes. The invoicing party shall comply with any additional reasonable requests of invoiced party in relation to such invoices. The Parties shall cooperate in any way reasonably requested, to obtain available reductions, credits or refunds of any VAT amount attributable to the supply under this Agreement, if applicable. The Parties shall cooperate in any way reasonably requested to enable VAT compliant behavior including providing evidence for VAT purposes in accordance with applicable VAT law. The Parties shall use Commercially Reasonable Efforts, where required, to avoid Company or its Affiliates being subject to any VAT obligations outside its residence. Merck will not reimburse any refunded, refundable or culpably unrefunded (foreign) VAT amounts of Company.

Merck will have the sole right to undertake and control the defense or settlement of any Third-Party Infringement Claim using counsel of its choice, at its cost and expense. If the Company is named as a defendant in such suit, Company will have the right to participate in such defence and settlement with its own counsel, at its cost. Neither Party will enter into any settlement of any Third-Party Infringement Claim that is instituted or threatened to be instituted against the other Party without the other Party’s prior written consent; except that, such consent will not be required if such settlement includes a release of all liability in favour of the other Party. At the request of Merck, Company will provide reasonable cooperation and assistance in connection with the Merck’s control of the defense or settlement of a Third-Party Infringement Claim.

All Intellectual Property Rights subsisting in any Company Platform Technology Inventions from time to time shall vest automatically and unconditionally in Company immediately on its creation. Merck assigns, and shall ensure that each relevant Merck’s Affiliate shall assign, to Company absolutely and from the date of their creation any such Intellectual Property Rights that, but for this Section 8.13, would vest in Merck or one of its Affiliates, and shall execute all documents and take any steps necessary to give effect to and confirm the foregoing.
1.1.3For the avoidance of doubt, Company has the exclusive right, in its sole discretion, to determine the steps to be taken to prosecute, maintain, enforce and defend any Company Platform IP. Merck shall: (a) at Company’s cost and expense, cooperate and provide such assistance and information as may be reasonably requested by Company in connection with any steps that Company determines to take pursuant to the previous sentence; and (b) notify Company in the event Merck becomes aware of any infringement, or suspected infringement, of any Company Platform Technology.
1.1.4Company hereby irrevocably and perpetually covenants that, at no time, will it or any of its Affiliates, directly or indirectly, sue Merck or any of its Affiliates under any Company Platform Technology IP with respect to Merck’s exercise of any of its rights granted by Company hereunder or the use or exploitation of any Collaboration IP.

In addition to the foregoing, Company may disclose Confidential Information, including the terms of this Agreement with the exception of any financial terms hereunder to a Third Party, if strictly necessary, via a mutually aligned redacted copy of this Agreement, such as (i) to potential or actual investors in subsequent funding rounds, or (ii) potential or actual counterparties to a Change of Control, if a bona fide term sheet at fair market value has been agreed between the parties, which are bound by confidentiality obligations at least as strict as provided for under this ARTICLE 9.
29


In making any disclosures set forth in Sections 9.3.1 through 9.3.5 above, the disclosing Party shall, where reasonably practicable, give such advance notice to the other Party of such disclosure requirement as is reasonable under the circumstances and will use its reasonable efforts to cooperate with the other Party in order to secure confidential treatment of such Confidential Information required to be disclosed. In addition, in connection with any permitted filing by either Party of this Agreement with any Governmental Body, including the U.S. Securities and Exchange Commission, the filing Party shall endeavour to obtain confidential treatment of economic, trade secret information and such other information as may be requested by the other Party, and shall provide the other Party with the proposed confidential treatment request with reasonable time for such other Party to provide comments, and shall include in such confidential treatment request all reasonable comments of the other Party.
1.4Protection of confidentiality of Merck Background IP in Research Program.

TERM AND TERMINATION
1.1Term and Expiration. This Agreement shall commence on the Effective Date and remain in full force and effect, unless terminated sooner in accordance with terms of this Agreement, until such date that no Milestone payments or Net Sales Payments under this Agreement are, or may become, payable (the “Term”), upon which all licenses to Merck in effect as at the effective date of expiration of this Agreement shall automatically become perpetual and irrevocable.
1.2Material Breach.
34


1.1.1Termination for Material Breach Generally. In the event that either Party materially breaches this Agreement (other than Merck’s breach of its obligations under Section 5.1 or 5.3), the other Party shall provide to the non-performing Party a written notification of such default specifying the nature of the breach. If such breach is not cured within [***] calendar days to the mutual satisfaction of both Parties, the other non-breaching Party shall have the right to terminate this Agreement without further notice. Termination by a Party for breach by the other Party shall be without prejudice to any damages or remedies to which it may be entitled from the other Party. For clarity, if the material breach is limited to a Collaboration Target, the termination right shall only apply with regard to the respective affected Collaboration Target, but not the Agreement in its entirety.
1.1.2Termination by Company for Diligence Breach by Merck. If Company reasonably considers at any time during the Term that Merck has breached its obligations under Section 5.1 or 5.3, Company shall notify Merck, and the Parties (each acting reasonably and in good faith) shall promptly discuss and agree a remediation plan for such breach. If the Parties have not agreed a remediation plan within [***] calendar days (or such other timeline as agreed by the Parties, acting reasonably and in good faith), or Merck has materially failed to comply with any agreed remediation plan, Company shall have the right to terminate this Agreement without further notice (and any such termination shall be without prejudice to any damages or remedies to which it may be entitled from Merck). For clarity, if the material breach is limited to a Collaboration Target, the termination right shall only apply with regard to the respective affected Collaboration Target, but not the Agreement in its entirety.
1.1.3Dispute. In case of a dispute in relation to whether Company has the right to terminate this Agreement in accordance with Section 12.2.2 (but, for the avoidance of doubt, not any dispute regarding any right to terminate pursuant to Section 12.2.1), no purported termination of this Agreement pursuant to Section 12.2.2 shall take effect until the resolution of such dispute.
1.3Technical Failure. In the event that both Parties mutually agree, with respect to a Collaboration Target, that despite Company having complied with its obligations pursuant to Section 3.1.2, (i) it is unlikely that the Criteria for a Collaboration Target can be achieved such that the Research Unit Leadership Team can reasonably be expected to approve the next upcoming Stage Gate Decision Point, or (ii) the time for Company to submit the DPED Data Package to Merck is expected to exceed the timeline set forth in the initial Research Plan for such Collaboration Target by [***] months or more, then either Party may terminate this Agreement with respect to such Collaboration Target immediately upon written notice to the other Party.
1.4Termination for Convenience. At any time during the Term, Merck may, at its convenience, terminate this Agreement in its entirety, or with respect to individual Collaboration Targets for which activities under a Research Plan are ongoing, upon [***] days’ prior written notice to Company.

15
299021913 v1



16.2Disclosure and ownership of Works
The Executive must immediately disclose to the Company all Works and all Intellectual Property Rights. Both the Works and all Intellectual Property Rights will (subject to sections 39 to 43 Patents Act 1977) belong to and be the absolute property of the Company or any other person the Company may nominate.
16.3Protection, registration and vesting of Works
The Executive shall immediately on request by the Company (whether during or after the Employment) and at the expense of the Company:

16
299021913 v1



17.TERMINATION
17.1Termination events
Notwithstanding the provisions of Clauses 3 and 10, the Company shall be entitled, but not bound, to terminate the Employment with immediate effect (without a notice period or payment in lieu of any notice period) by giving to the Executive notice in writing at any time after the occurrence of any one or more of the following events (each being termination for “Cause”):
(a)if the Executive is guilty of any gross misconduct or behaviour which tends to bring himself or the Company or any Group Company into disrepute; or
(b)if the Executive commits any material or persistent breach of this Agreement (in the case of a non-material persistent breach, having been given notice in writing of the breach and a reasonable opportunity to rectify the breach) or unreasonably fails to comply with any reasonable order or direction of the Board; or
(c)if he becomes insolvent or bankrupt or compounds with or grants a trust deed for the benefit of his creditors; or
(d)if his behaviour (whether or not in breach of this Agreement) can reasonably be regarded as materially prejudicial to the interests of the Company or any Group Company, including if he is found guilty of any criminal offence punishable by imprisonment (whether or not such sentence is actually imposed); or
(e)if he has an order made against him disqualifying him from acting as a company director; or
(f)if the Executive is found guilty of any offence of bribery under the Bribery Act 2010, or other bribery legislation in any other jurisdiction, breach of Clause 15 of this Agreement or the Company’s Anti-Bribery and Corruption Policy; or
(g)if the Executive commits any material breach or persistent but non-material breach of the Articles of Association of the Company or any Group Company (in the case of a persistent but non-material breach, having been given notice in writing of the breach and a reasonable opportunity to rectify the breach).
17.2Termination on resignation as director
If the Executive resigns as a director of the Company or any Group Company (otherwise than at the request of the Board or, in respect of a directorship of an entity other than the Parent, with the prior agreement of the applicable Group Company), he shall be deemed to have voluntarily resigned from the Employment with effect from the date of his resignation, unless the Company agrees with the Executive that the Employment should continue, in which case the Employment may be subject to any terms and conditions stipulated by the Company in its absolute discretion.
17.3No damages or payment in lieu of notice
In the event of the Employment being terminated pursuant to Clause 17.1 the Executive shall not be entitled to receive any payment in lieu of notice nor make any claim against the Company or any Group Company for damages for loss of office or termination of the Employment. Regardless of this, the
17
299021913 v1



termination shall be without prejudice to the continuing obligations of the Executive under this Agreement.
17.4Termination by the Company without Cause or resignation by the Executive for Good Reason (in connection with a Change in Control)
In the event that the Company terminates the Executive’s Employment without Cause or the Executive resigns for Good Reason, in either case, within (3) three months prior to, upon or within (12) twelve months following the effective date of a Change in Control (such period, the “Change in Control Measurement Period”) then the Executive shall be entitled to his salary and benefits pursuant to the terms of this Agreement through the Termination Date and, subject to the Executive (i) executing a Settlement Agreement; (ii) returning all Company property; (iii) complying with the Executive’s termination and post-termination obligations under this Agreement; (iv) complying with the terms of the Settlement Agreement, including without limitation any non-disparagement and confidentiality provisions contained therein; and (v) resigning from any other positions held with the Company or any Group Company, including any position on the Board, effective no later than the Termination Date (or such other date as requested by the Board), the Executive shall be eligible to receive the following severance benefits (collectively the “CIC Severance Benefits”):
(a)The Company will pay the Executive severance pay in the form of continuation of the Executive’s then-current Basic Salary (ignoring any decrease that forms the basis for the Executive’s resignation for Good Reason, if applicable) for twelve (12) months following the Termination Date (such period of time, the “CIC Severance Period”, and such aggregate Basic Salary amount payable, the “CIC Severance”). The CIC Severance will be paid in substantially equal instalments on the Company’s regular payroll schedule over the CIC Severance Period, subject to such deductions as the Company is required by law to make, shall be reduced by any Basic Salary received by the Executive during any period of Garden Leave and shall be inclusive of any PILON; provided, however that no portion of the CIC Severance (except for any PILON instalment which is due) will be paid prior to the date that the general release of claims in the Settlement Agreement becomes effective (the “Release Date”), and any such payments that are otherwise scheduled to be made prior to the Release Date shall instead accrue and be made on the first regular payroll date following the Release Date;
(b)The Company will pay to the Executive in monthly instalments, subject to such deductions as the Company is required by law to make, a fully taxable cash payment equal to: (i) the coverage premium for the Executive (and the Executive’s covered dependents, as applicable) health insurance coverage in effect on the Termination Date until the earliest of: (1) the close of the CIC Severance Period or; (2) the date when the Executive becomes eligible for substantially equivalent health insurance coverage in connection with new employment or self-employment; and (ii) the Company’s employer pension contributions that would have been received by the Executive during the CIC Severance Period had Employment continued, at the rate payable by the Company immediately prior to the Termination Date;
(c)The Company will make a lump sum cash payment to the Executive in an amount equal to one (1) times the Target Bonus for the year in which the Termination Date occurs, subject to such deductions as the Company is required by law to make, which will be paid in a lump sum on or before the 60th day following the Termination Date;
18
299021913 v1



(d)The Company will make a lump sum cash payment to the Executive in an amount equal to any earned but unpaid Annual Bonus for the year immediately preceding the year in which the Executive’s employment terminates, such payment to be made no later than the normal payment date for such Annual Bonus; and
(e)Effective as of the Termination Date, the vesting and exercisability of all outstanding equity awards covering the Parent’s ordinary shares that are held by the Executive immediately prior to the Termination Date shall be accelerated in full.
The CIC Severance Benefits provided to the Executive pursuant to this clause 17.4 are in lieu of, and not in addition to, any benefits to which the Executive may otherwise be entitled under any Company severance plan, policy, or program.
Any damages caused by the termination of the Executive’s employment without Cause during the Change in Control Measurement Period would be difficult to ascertain; therefore, the CIC Severance Benefits for which the Executive is eligible pursuant to this clause 17.4 in exchange for the Settlement Agreement are agreed to by the parties as liquidated damages, to serve as full compensation, and not a penalty.
17.5Termination by the Company without Cause or resignation by the Executive for Good Reason (not in connection with a Change in Control)
In the event that the Company terminates the Executive’s Employment without Cause or the Executive resigns for Good Reason, in either case, outside a Change in Control Measurement Period then the Executive shall be entitled to his salary and benefits pursuant to the terms of this Agreement through the Termination Date and, subject to the Executive (i) executing a Settlement Agreement; (ii) returning all Company property; (iii) complying with the Executive’s termination and post-termination obligations under this Agreement; (iv) complying with the terms of the Settlement Agreement, including without limitation any non-disparagement and confidentiality provisions contained therein; and (v) resigning from any other positions held with the Company or any Group Company, including any position on the Board, effective no later than the Termination Date (or such other date as requested by the Board), the Executive shall be eligible to receive the following severance benefits (collectively the “Non-CIC Severance Benefits”):
(a)The Company will pay the Executive severance pay in the form of continuation of the Executive’s then-current Basic Salary (ignoring any decrease that forms the basis for the Executive’s resignation for Good Reason, if applicable) for twelve (12) months following the Termination Date (such period of time, the “Non-CIC Severance Period”, and such aggregate Basic Salary amount payable, the “Non-CIC Severance”). The Non-CIC Severance will be paid in substantially equal instalments on the Company’s regular payroll schedule over the Non-CIC Severance Period, subject to such deductions as the Company is required by law to make, shall be reduced by any Basic Salary received by the Executive during any period of Garden Leave and shall be inclusive of any PILON; provided, however that no portion of the Non-CIC Severance (except for any PILON instalment which is due) will be paid prior to the date that the general release of claims in the Settlement Agreement becomes effective (the “Release Date”), and any such payments that are otherwise scheduled to be made prior to the Release Date shall instead accrue and be made on the first regular payroll date following the Release Date;
19
299021913 v1



(b)The Company will pay to the Executive in monthly instalments, subject to such deductions as the Company is required by law to make, a fully taxable cash payment equal to the coverage premium for the Executive (and the Executive’s covered dependents, as applicable) health insurance coverage in effect on the Termination Date and/or provide the Executive with continued access to the Company’s health insurance scheme until the earliest of: (1) the twelve (12) month anniversary of the date on which notice to terminate the Employment is given in accordance with the terms of this Agreement or; (2) the date when the Executive becomes eligible for substantially equivalent health insurance coverage in connection with new employment or self-employment; and
(c)The Company will pay the Executive an amount equal to the prorated portion of the Annual Bonus for the calendar year in which the Termination Date occurs (calculated using the Target Bonus for the number of days in that calendar year that have passed prior to the Termination Date or, if earlier, the date of commencement of any period of Garden Leave) (the “Pro-Rated Bonus”). The Pro-Rated Bonus will be subject to standard deductions and withholdings and will be paid in a lump sum on or before the 60th day following the Termination Date;
(d)The Company will make a lump sum cash payment to the Executive in an amount equal to any earned but unpaid Annual Bonus for the year immediately preceding the year in which the Executive’s employment terminates, such payment to be made no later than the normal payment date for such Annual Bonus; and
(e)Effective as of the Termination Date, the vesting and exercisability of all outstanding equity awards covering the Parent’s ordinary shares that are held by the Executive immediately prior to the Termination Date shall be accelerated such that Executive shall be treated, for vesting purposes, as if he had vested pro rata until the Termination Date or, if later, the date on which his employment would have terminated had he not been paid a PILON (save that such equity awards shall not vest as to more than 100 per cent.).
The Non-CIC Severance Benefits provided to the Executive pursuant to this clause 17.5 are in lieu of, and not in addition to, any benefits to which the Executive may otherwise be entitled under any Company severance plan, policy, or program.
Any damages caused by the termination of the Executive’s employment without Cause outside the Change in Control Measurement Period would be difficult to ascertain; therefore, the Non-CIC Severance Benefits for which the Executive is eligible pursuant to this clause 17.5 in exchange for the Settlement Agreement are agreed to by the parties as liquidated damages, to serve as full compensation, and not a penalty.
17.6Death or Disability
(a)In the event of the Executive’s death while employed pursuant to this Agreement, all obligations of the parties hereunder and the Executive’s employment shall terminate immediately, but neither the Executive nor their legal representatives will receive the CIC Severance Benefits or the Non-CIC Benefits. Notwithstanding the foregoing, nothing in this clause or in this Agreement shall preclude the Executive from remaining eligible to receive any payments or benefits pursuant to any life assurance or permanent health insurance policy under which the Executive participates, subject to and in accordance with the terms of this Agreement, such policy and applicable law.
20
299021913 v1



(b)Subject to applicable law, the Company shall at all times have the right, upon written notice to the Executive in accordance with clause 3.2(a), to terminate this Agreement based on the Executive’s Disability (as defined below). Termination by the Company of the Executive’s employment based on “Disability” shall mean termination because the Executive is unable due to a physical or mental condition to perform the essential functions of their position (after taking into account any applicable reasonable adjustments) for twelve (12) months in the aggregate during any eighteen (18) month period or based on the written certification by two qualified licensed physicians of the likely continuation of such condition for such period. In the event the Executive’s employment is terminated based on Disability, the Executive will not receive the CIC Severance Benefits or the Non-CIC Benefits. Notwithstanding the foregoing, nothing in this clause or in this Agreement shall preclude the Executive from remaining eligible to receive any payments or benefits pursuant to any life assurance or permanent health insurance policy under which the Executive participates, subject to and in accordance with the terms of this Agreement, such policy and applicable law. The Company will not terminate this Agreement if to do so would deprive the Executive of payments he is receiving under the Company’s applicable permanent health insurance scheme.
18.EVENTS UPON TERMINATION
18.1Obligations upon termination
Immediately upon the termination of the Employment howsoever arising or immediately at the request of the Board at any time after either the Company or the Executive has served notice of termination of the Employment, the Executive shall:
(a)deliver to the Company all Works, materials within the scope of Clause 15.2 and all other materials and property including credit or charge cards, mobile telephone, computer equipment, disks and software, passwords, encryption keys or the like, keys, security pass, letters, stationery, documents, files, films, records, reports, plans and papers (in whatever format including electronic) and all copies thereof used in or relating to the business of the Company or the Group which are in the possession of or under the control of the Executive;
(b)resign (without claim for compensation) as a director and from all other offices held by him in the Company or any Group Company or otherwise by virtue of the Employment.

(c)transfer without payment, to the Company, or as the Company may direct, any shares or other securities held by the Executive as nominee or trustee for the Company or any Group Company;

Exhibit 97.1
Exscientia plc
Incentive Compensation Recoupment Policy
1.Introduction
The Remuneration Committee (the “Remuneration Committee”) of the Board of Directors (the “Board”) of Exscientia plc, a public limited company incorporated under the laws of England and Wales (the “Company”), has determined that it is in the best interests of the Company and its shareholders to adopt this Incentive Compensation Recoupment Policy (this “Policy”) providing for the Company’s recoupment of Recoverable Incentive Compensation that is received by Covered Officers of the Company under certain circumstances. Certain capitalized terms used in this Policy have the meanings given to such terms in Section 3 below.
This Policy is designed to comply with, and shall be interpreted to be consistent with, Section 10D of the Exchange Act, Rule 10D-1 promulgated thereunder (“Rule 10D-1”) and Nasdaq Listing Rule 5608 (the “Listing Standards”).
2.Effective Date
This Policy shall apply to all Incentive Compensation that is received by a Covered Officer on or after October 2, 2023 (the “Effective Date”). Incentive Compensation is deemed “received” in the Company’s financial year in which the Financial Reporting Measure specified in the Incentive Compensation award is attained, even if the payment or grant of such Incentive Compensation occurs after the end of that period.
3.Definitions
Accounting Restatement” means an accounting restatement that the Company is required to prepare due to the material noncompliance of the Company with any financial reporting requirement under U.S. securities laws, including any required accounting restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period.
Accounting Restatement Date” means the earlier to occur of (a) the date that the Board, a committee of the Board authorized to take such action, or the officer or officers of the Company authorized to take such action if Board action is not required, concludes, or reasonably should have concluded, that the Company is required to prepare an Accounting Restatement, or (b) the date that a court, regulator or other legally authorized body directs the Company to prepare an Accounting Restatement.
Administrator” means the Remuneration Committee or, in the absence of such committee, the Board.
Code” means the U.S. Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder.
Covered Officer” means each current and former Executive Officer.
Exchange” means the Nasdaq Stock Market.
Exchange Act” means the U.S. Securities Exchange Act of 1934, as amended.
Executive Officer” means the Company’s president, principal financial officer, principal accounting officer (or if there is no such accounting officer, the controller), any vice-president of the Company in charge of a principal business unit, division, or function (such as sales, administration, or



finance), any other officer who performs a policy-making function, or any other person who performs similar policy-making functions for the Company. Executive officers of the Company’s parent(s) or subsidiaries are deemed executive officers of the Company if they perform such policy-making functions for the Company. Policy-making function is not intended to include policy-making functions that are not significant. Identification of an executive officer for purposes of this Policy would include at a minimum executive officers identified pursuant to Item 401(b) of Regulation S-K promulgated under the Exchange Act.
Financial Reporting Measures” means measures that are determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, and any measures derived wholly or in part from such measures, including Company share price and total shareholder return (“TSR”). A measure need not be presented in the Company’s financial statements or included in a filing with the SEC in order to be a Financial Reporting Measure.
Incentive Compensation” means any compensation that is granted, earned or vested based wholly or in part upon the attainment of a Financial Reporting Measure.
Lookback Period” means the three completed financial years immediately preceding the Accounting Restatement Date, as well as any transition period (resulting from a change in the Company’s financial year) within or immediately following those three completed financial years (except that a transition period of at least nine months shall count as a completed financial year). Notwithstanding the foregoing, the Lookback Period shall not include financial years completed prior to the Effective Date.
Recoverable Incentive Compensation” means Incentive Compensation received by a Covered Officer during the Lookback Period that exceeds the amount of Incentive Compensation that would have been received had such amount been determined based on the Accounting Restatement, computed without regard to any taxes paid (i.e., on a gross basis without regard to tax or social security withholdings and other deductions). For any compensation plans or programs that take into account Incentive Compensation, the amount of Recoverable Incentive Compensation for purposes of this Policy shall include, without limitation, the amount contributed to any notional account based on Recoverable Incentive Compensation and any earnings to date on that notional amount. For any Incentive Compensation that is based on share price or TSR, where the Recoverable Incentive Compensation is not subject to mathematical recalculation directly from the information in an Accounting Restatement, the Administrator will determine the amount of Recoverable Incentive Compensation based on a reasonable estimate of the effect of the Accounting Restatement on the share price or TSR upon which the Incentive Compensation was received. The Company shall maintain documentation of the determination of that reasonable estimate and provide such documentation to the Exchange in accordance with the Listing Standards.
SEC” means the U.S. Securities and Exchange Commission.
4.Recoupment
(a)Applicability of Policy. This Policy applies to Incentive Compensation received by a Covered Officer (i) after beginning services as an Executive Officer, (ii) who served as an Executive Officer at any time during the performance period for such Incentive Compensation, (iii) while the Company had a class of securities listed on a national securities exchange or a national securities association, and (iv) during the Lookback Period.
(b)Recoupment Generally. Pursuant to the provisions of this Policy, if there is an Accounting Restatement, the Company must reasonably promptly recoup the full amount of the Recoverable Incentive Compensation, unless the conditions of one or more subsections of Section 4(c) of this Policy are met and the Remuneration Committee, or, if such committee does not consist solely of independent directors, a majority of the independent directors serving on the Board, has made a determination that recoupment would be impracticable. Recoupment is required regardless of whether the Covered Officer engaged in any misconduct and regardless of fault, and the Company’s obligation to recoup Recoverable Incentive Compensation is not dependent on whether or when any restated financial statements are filed.
2



(c)Impracticability of Recovery. Recoupment may be determined to be impracticable if, and only if:
(i)the direct expense paid to a third party to assist in enforcing this Policy would exceed the amount of the applicable Recoverable Incentive Compensation; provided that, before concluding that it would be impracticable to recover any amount of Recoverable Incentive Compensation based on expense of enforcement, the Company shall make a reasonable attempt to recover such Recoverable Incentive Compensation, document such reasonable attempt(s) to recover, and provide that documentation to the Exchange in accordance with the Listing Standards;
(ii)recoupment of the applicable Recoverable Incentive Compensation would violate home country law where that law was adopted prior to November 28, 2022; provided that, before concluding that it would be impracticable to recover any amount of Recoverable Incentive Compensation based on violation of home country law, the Company shall obtain an opinion of home country counsel, acceptable to the Exchange, that recoupment would result in such a violation, and shall provide such opinion to the Exchange in accordance with the Listing Standards; or
(iii)recoupment of the applicable Recoverable Incentive Compensation would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of the Company, to fail to meet the requirements of Code Section 401(a)(13) or Code Section 411(a) and regulations thereunder.
(d)Sources of Recoupment. To the extent permitted by applicable law, the Administrator shall, in its sole discretion, determine the timing and method for recouping Recoverable Incentive Compensation hereunder, provided that such recoupment is undertaken reasonably promptly. The Administrator may, in its discretion, seek recoupment from a Covered Officer from any of the following sources or a combination thereof, whether the applicable compensation was approved, awarded, granted, payable or paid to the Covered Officer prior to, on or after the Effective Date: (i) direct repayment of Recoverable Incentive Compensation previously paid to the Covered Officer; (ii) cancelling prior cash or equity-based awards (whether vested or unvested and whether paid or unpaid); (iii) cancelling or offsetting against any planned future cash or equity-based awards; (iv) forfeiture of deferred compensation, subject to compliance with Code Section 409A (if applicable) or any equivalent local laws applicable to the Covered Officer; and (v) any other method authorized by applicable law or contract. Subject to compliance with any applicable law, the Administrator may effectuate recoupment under this Policy from any amount otherwise payable to the Covered Officer, including amounts payable to such individual under any otherwise applicable Company plan or program, e.g., base salary, bonuses or commissions and compensation previously deferred by the Covered Officer. The Administrator need not utilize the same method of recovery for all Covered Officers or with respect to all types of Recoverable Incentive Compensation.
(e)No Indemnification of Covered Officers. Notwithstanding any indemnification agreement, applicable insurance policy or any other agreement or provision of the Company’s articles of association or bylaws to the contrary, no Covered Officer shall be entitled to indemnification or advancement of expenses in connection with any enforcement of this Policy by the Company, including paying or reimbursing such Covered Officer for insurance premiums to cover potential obligations to the Company under this Policy.
(f)Indemnification of Administrator. Any members of the Administrator, and any other members of the Board who assist in the administration of this Policy, shall not be personally liable for any action, determination or interpretation made with respect to this Policy and shall be indemnified by the Company to the fullest extent under applicable law and Company policy with respect to any such action, determination or interpretation. The foregoing sentence shall not limit any other rights to indemnification of the members of the Board under applicable law or Company policy.
(g)No “Good Reason” for Covered Officers. Any action by the Company to recoup or any recoupment of Recoverable Incentive Compensation under this Policy from a Covered Officer shall not be deemed (i) “good reason” for resignation or to serve as a basis for a claim of constructive
3



termination under any benefits or compensation arrangement applicable to such Covered Officer, or (ii) to constitute a breach of a contract or other arrangement to which such Covered Officer is party.
5.Administration
Except as specifically set forth herein, this Policy shall be administered by the Administrator. The Administrator shall have full and final authority to make any and all determinations required under this Policy. Any determination by the Administrator with respect to this Policy shall be final, conclusive and binding on all interested parties and need not be uniform with respect to each individual covered by this Policy. In carrying out the administration of this Policy, the Administrator is authorized and directed to consult with the full Board or such other committees of the Board as may be necessary or appropriate as to matters within the scope of such other committee’s responsibility and authority. Subject to applicable law, the Administrator may authorize and empower any officer or employee of the Company to take any and all actions that the Administrator, in its sole discretion, deems necessary or appropriate to carry out the purpose and intent of this Policy (other than with respect to any recovery under this Policy involving such officer or employee).
6.Severability
If any provision of this Policy or the application of any such provision to a Covered Officer shall be adjudicated to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of this Policy, and the invalid, illegal or unenforceable provisions shall be deemed amended to the minimum extent necessary to render any such provision or application enforceable.
7.No Impairment of Other Remedies
Nothing contained in this Policy, and no recoupment or recovery as contemplated herein, shall limit any claims, damages or other legal remedies the Company or any of its affiliates may have against a Covered Officer arising out of or resulting from any actions or omissions by the Covered Officer. This Policy does not preclude the Company or any subsidiary thereof from taking any other action to enforce a Covered Officer’s obligations to the Company, including, without limitation, termination of employment and/or institution of civil proceedings. This Policy is in addition to the requirements of Section 304 of the Sarbanes-Oxley Act of 2002 (“SOX 304”) that are applicable to the Company’s Chief Executive Officer and Chief Financial Officer and to any other compensation recoupment policy and/or similar provisions in any employment, equity plan, equity award, or other individual agreement, to which the Company or any subsidiary thereof is a party or which the Company or any subsidiary thereof has adopted or may adopt and maintain from time to time; provided, however, that compensation recouped pursuant to this Policy shall not be duplicative of compensation recouped pursuant to SOX 304 or any such compensation recoupment policy and/or similar provisions in any such employment, equity plan, equity award, or other individual agreement except as may be required by law.
8.Amendment; Termination
The Administrator may amend, terminate or replace this Policy or any portion of this Policy at any time and from time to time in its sole discretion. The Administrator shall amend this Policy as it deems necessary to comply with applicable law or any Listing Standard.
9.Successors
This Policy shall be binding and enforceable against all Covered Officers and, to the extent required by Rule 10D-1 and/or the applicable Listing Standards, their beneficiaries, heirs, executors, administrators or other legal representatives.
10.    Required Filings
    The Company shall make any disclosures and filings with respect to this Policy that are required by law, including as required by the SEC.
