Currency Presentation and Currency Translation

Unless otherwise indicated, all references to “dollars,” “$,” “U.S. $” or “U.S. dollars” are to the lawful currency of the United States. All references in this Report to “euro” or “€ ” are to the currency introduced at the start of the third stage of the European Economic and Monetary Union pursuant to the Treaty establishing the European Community, as amended. We prepare our financial statements in U.S. dollars.

The functional currency for most of our operations is the euro. With respect to our financial statements, the translation from the euro to U.S. dollars is performed for balance sheet accounts using exchange rates in effect at the balance sheet date and for revenue and expense accounts using a weighted average exchange rate during the period. The resulting translation adjustments are recorded as a component of other comprehensive income.

Where in this Report we refer to amounts in euros, we have for your convenience also in certain cases provided a conversion of those amounts to U.S. dollars in parentheses. Where the numbers refer to a specific balance sheet account date or financial statement account period, we have used the exchange rate that was used to perform the conversions of the applicable financial statement. In all other instances, unless otherwise indicated, the conversions have been made using the noon buying rate of € 1.00 to U.S. $1.142270 based on www.oanda.com as of June 30, 2017.

Forward Looking Statements

This section and other parts of this Quarterly Report on Form 10-Q contains forward looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that involve risks and uncertainties, principally in the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” All statements other than statements of historical fact contained in this Quarterly Report on Form 10-Q, including statements regarding future events, our future financial performance, expectations for growth and revenues, anticipated timing and amounts of milestone and other payments under collaboration agreements, business strategy and plans, objectives of management for future operations, timing and outcome of legal and other proceedings, and our ability to finance our operations are forward-looking statements. We have attempted to identify forward-looking statements by terminology including “anticipates,” “believes,” “can,” “continue,” “ongoing,” “could,” “estimates,” “expects,” “intends,” “may,” “appears,” “future,” “likely,” “plans,” “potential,” “projects,” “predicts,” “should,” “would,” or “will” or the negative of these terms or other comparable terminology. Although we do not make forward looking statements unless we believe we have a reasonable basis for doing so, we cannot guarantee their accuracy. These statements are only predictions and involve known and unknown risks, uncertainties and other factors, including the risks outlined under “Risk Factors” or elsewhere in our most recent Annual Report on Form 10-K, which may cause our or our industry’s actual results, levels of activity, performance or achievements expressed or implied by these forward-looking statements to differ materially.

Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time and it is not possible for us to predict all risk factors, nor can we address the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause our actual results to differ materially from those contained in any forward-looking statements. Actual results could differ materially from our forward-looking statements due to a number of factors, including, without limitation, risks related to: the results of our research and development activities, including uncertainties relating to the discovery of potential drug candidates and the preclinical and ongoing or planned clinical testing of our drug candidates; the early stage of our drug candidates presently under development; our ability to obtain and, if obtained, maintain regulatory approval of our current drug candidates and any of our other future drug candidates; our need for substantial additional funds in order to continue our operations and the uncertainty of whether we will be able to obtain the funding we need; our future financial performance; our ability to retain or hire key scientific or management personnel; our ability to protect our intellectual property rights that are valuable to our business, including patent and other intellectual property rights; our dependence on third-party manufacturers, suppliers, research organizations, testing laboratories and other potential collaborators; our ability to meet milestones; our ability to successfully market and sell our drug candidates in the future as needed; the size and growth of the potential markets for any of our approved drug candidates, and the rate and degree of market acceptance of any of our approved drug candidates; competition in our industry; and regulatory developments in the United States and foreign countries.

You should not place undue reliance on any forward-looking statement, each of which applies only as of the date of this Quarterly Report on Form 10-Q. Before you invest in our securities, you should be aware that the occurrence of the events described in Part I, Item 1A (Risk Factors) of our Annual Report on Form 10-K for the year ended December 31, 2016 filed on March 30, 2017, could negatively affect our business, operating results, financial condition and stock price. All forward-looking statements included in this document are based on information available to us on the date hereof, and except as required by law, we undertake no obligation to update or revise publicly any of the forward-looking statements after the date of this Quarterly Report on Form 10-Q to conform our statements to actual results or changed expectations.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. Interim Consolidated Financial Statements

The accompanying unaudited interim condensed consolidated financial statements of Pieris Pharmaceuticals, Inc. (“Pieris” or the “Company”) were prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information. All significant intercompany balances and transactions have been eliminated in the consolidation. Certain information and footnotes normally included in financial statement prepared in accordance with U.S. GAAP have been omitted pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, the statements do not include all of the information and notes required by U.S. GAAP for complete annual consolidated financial statements. It is recommended that these financial statements be read in conjunction with the consolidated financial statements and related footnotes that appear in the Annual Report on Form 10-K of the Company for the year ended December 31, 2016 filed with the SEC on March 30, 2017 (the “2016 Annual Report”).

In the opinion of management, the unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited condensed consolidated financial statements for the year ending December 31, 2016, and all adjustments, including normal recurring adjustments, considered necessary for the fair presentation of the Company’s unaudited interim consolidated financial statements have been included. The results of operations, for the three and six months ended June 30, 2017, are not necessarily indicative of the results that may be expected for the year ending December 31, 2017 or any future period.

Use of estimates

The preparation of the condensed consolidated financial statements in accordance with U.S. GAAP requires management to make estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities, the reported amounts of revenues, and expenses in the financial statements and disclosures in the accompanying notes. Significant estimates are used for, but are not limited to, revenue recognition, deferred tax assets, liabilities and valuation allowances, fair value of stock options and various accruals. Management evaluates its estimates on an ongoing basis. Actual results and outcomes could differ materially from management’s estimates, judgments and assumptions.

2. Critical Accounting Policies

Research and development expenses

Research and development expenses are charged to the condensed consolidated statement of operations as incurred. Research and development expenses are comprised of costs incurred in performing research and development activities, including salaries and benefits, facilities costs, pre-clinical and clinical costs, contract services, consulting, depreciation and amortization expense, and other related costs. Costs associated with acquired technology, in the form of upfront fees or milestone payments, are charged to research and development expense as incurred.

Revenue Recognition

Pieris has entered into several licensing and development agreements with collaboration partners for the development of Anticalin ^® therapeutics against a variety of targets in diseases and conditions. The terms of these agreements contain multiple elements and deliverables, which may include: (i) licenses, or options to obtain licenses, to Pieris’ Anticalin technology and (ii) research activities to be performed on behalf of the collaborative partner. Payments to Pieris, under these agreements, may include upfront fees (which include license and option fees), payments for research activities, payments based upon the achievement of certain milestones and royalties on product sales. There are no performance, cancellation, termination, or refund provisions in any of the arrangements that could result in material financial consequences to Pieris. Pieris follows the provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 605-25, Revenue Recognition—Multiple-Element Arrangements (“605-25”) and ASC Topic 605-28, Revenue Recognition—Milestone Method (“605-28”) in accounting for these agreements.

Multiple-Element Arrangements

When evaluating multiple-element arrangements, Pieris identifies the deliverables included within the agreement and evaluates which deliverables represent separate units of accounting based on whether the delivered element has stand-alone value to the customer or if the arrangement includes a general right of return for delivered items.

The consideration received is allocated among the separate units of accounting using the relative selling price method, and the applicable revenue recognition criteria are applied to each of the separate units of accounting. Pieris has used best estimate of selling price (“BESP”) methodology to estimate the selling price for licenses and options to acquire additional licenses to its proprietary

technology because Pieris does not have vendor specific objective evidence (“VSOE”) or third party evidence (“TPE”) of selling price for these deliverables. To determine the estimated selling price of a license to its proprietary technology, Pieris considers market conditions as well as entity-specific factors, including those factors contemplated in negotiating the agreements, terms of previous collaborative agreements, similar agreements entered into by third parties, market opportunity, estimated development costs, probability of success, and the time needed to commercialize a product candidate pursuant to the license. In validating Pieris’ best estimate of selling price, Pieris evaluates whether changes in the key assumptions used to determine the BESP will have a significant effect on the allocation of arrangement consideration among multiple deliverables.

Multiple element arrangements, such as license and development arrangements, are analyzed to determine whether the deliverables, which often include licenses and performance obligations such as research and development services and steering committee services, can be separated or whether they must be accounted for as a combined unit of accounting in accordance with U.S. GAAP. The Company recognizes the arrangement consideration allocated to licenses as revenue upon delivery of the license only if the license has stand-alone value. If the license is considered not to have stand-alone value, the license would then be combined with other undelivered elements into a combined unit of accounting and the license payments and payments for performance obligations would be recognized as revenue when the revenue recognition criteria have been satisfied for the last deliverable within the unit of accounting. In the case of combined units of accounting that include delivered licenses and undelivered services to be provided over time, revenue would be recognized over the estimated period during which services will be provided.

If the Company is involved in a steering committee as part of a multiple element arrangement, the Company assesses whether its involvement constitutes a performance obligation or a right to participate. Steering committee services that are determined to be performance obligations, are combined with other research services or performance obligations required under an arrangement, if any, in determining the level of effort required in an arrangement and the period over which the Company expects to complete its aggregate performance obligations.

The Company recognizes arrangement consideration allocated to each unit of accounting when all of the revenue recognition criteria in ASC 605-25 are satisfied for that particular unit of accounting. For each unit of accounting, the Company must determine the period over which the performance obligations will be performed and revenue will be recognized. Revenue will be recognized using either a proportional performance or straight-line method. The Company recognizes revenue using the proportional performance method provided the Company can reasonably estimate the level of effort required to complete its performance obligations under an arrangement and such performance obligations are provided on a best-effort basis. Full-time equivalents are typically used as the measure of performance.

If the Company cannot reasonably estimate when its performance obligation either ceases or becomes inconsequential and perfunctory, then revenue is deferred until the Company can reasonably estimate when the performance obligation ceases or becomes inconsequential.

Significant management judgment is required in determining the level of effort required under an arrangement and the period over which the Company is expected to complete its performance obligations under an arrangement.

The accounting treatment for options granted to collaborators is dependent upon the nature of the option granted to the collaborative partner. Options are considered substantive if, at the inception of an agreement, Pieris is at risk as to whether the collaborative partner will choose to exercise the options to secure additional goods or services. Factors that are considered in evaluating whether options are substantive include the overall objective of the arrangement, the benefit the collaborator might obtain from the agreement without exercising the options, the cost to exercise the options relative to the total upfront consideration, and the additional financial commitments or economic penalties imposed on the collaborator as a result of exercising the options.

In arrangements where options to obtain additional deliverables are considered substantive, Pieris determines whether the optional licenses are priced at a significant and incremental discount. If the prices include a significant and incremental discount, the option is considered a deliverable in the arrangement. However, if not priced at a discount, the option is not considered a deliverable in the arrangement. When a collaborator exercises an option to acquire an additional license, the exercise fee that is attributed to the additional license and any incremental discount allocated at inception are recognized in a manner consistent with the treatment of up-front payments for licenses ( i.e. , license and research services). In the event an option expires un-exercised, any incremental discounts deferred at the inception of the arrangement are recognized into revenue upon expiration. For options that are non-substantive, the additional licenses to which the options pertain are considered deliverables upon inception of the arrangement, and Pieris applies the multiple-element revenue recognition criteria to determine accounting treatment.

Payments or reimbursements resulting from Pieris’ research and development efforts in multi-element arrangements, in which Pieris’ research and development efforts are considered to be a deliverable, are included in allocable consideration and allocated to the units of accounting. These reimbursements are recognized as the services are performed and are presented on a gross basis so long as there

is persuasive evidence of an arrangement, the fee is fixed or determinable, and collection of the related receivable is reasonably

assured. Revenue recognized cannot exceed the amount that has been earned and has been billed or is currently billable. Amounts received prior to satisfying the above revenue recognition criteria are recorded as deferred revenue in the accompanying balance sheets.

Milestone Payments and Royalties

At the inception of each agreement that includes milestone payments, Pieris evaluates whether each milestone is substantive and at risk to both parties on the basis of the contingent nature of the milestone. This evaluation includes an assessment of whether: (a) the consideration is commensurate with either (1) the entity’s performance to achieve the milestone, or (2) the enhancement of the value of the delivered item(s) as a result of a specific outcome resulting from the entity’s performance to achieve the milestone, (b) the consideration relates solely to past performance and (c) the consideration is reasonable relative to all of the deliverables and payment terms within the arrangement. Pieris evaluates factors such as the scientific, regulatory, commercial and other risks that must be overcome to achieve the respective milestone, the level of effort and investment required to achieve the respective milestone and whether the milestone consideration is reasonable relative to all deliverables and payment terms in the arrangement in making this assessment.

Pieris aggregates milestones into four categories: (i) research milestones, (ii) development milestones, (iii) commercial milestones and (iv) sales milestones. Research milestones are typically achieved upon reaching certain success criteria as defined in each agreement related to developing an Anticalin protein against the specified target. Development milestones are typically reached when a compound reaches a defined phase of clinical research or passes such phase, or upon gaining regulatory approvals. Commercial milestones are typically achieved when an approved pharmaceutical product reaches the status for commercial sale, including regulatory approval. Sales milestones are certain defined levels of net sales by the licensee, such as when a product first achieves global sales or annual sales of a specified amount.

For revenues from research, development, and commercial milestone payments, if the milestones are deemed substantive and the milestone payments are nonrefundable, such amounts are recognized entirely upon successful accomplishment of the milestones, assuming all other revenue recognition criteria are met. Milestones that are not considered substantive are accounted for as contingent revenue and will be recognized when achieved to the extent the Company has no remaining performance obligations under the arrangement. Revenues from sales milestone payments are accounted for as royalties and are recorded as revenue upon achievement of the milestone, assuming all other revenue recognition criteria are met. Royalty payments are recognized in revenues based on the timing of royalty payments earned in accordance with the agreements, which typically is the period when the relevant sales occur, assuming all other revenue recognition criteria are met.

3. Revenues

General

Pieris has not generated revenues from product sales to date. Pieris has generated revenues from: (i) license and collaboration agreements, which include upfront payments for licenses or options to obtain licenses, payments for research and development services and milestone payments and (ii) government grants.

F.Hoffmann-La Roche Ltd. and Hoffmann- La Roche Inc.

In December 2015, the Company entered into a Research Collaboration and License Agreement (the “Roche Agreement”) with F.Hoffmann- La Roche Ltd. and Hoffmann- La Roche Inc., (“Roche”), for the research, development, and commercialization of Anticalin ^® -based drug candidates against a predefined, undisclosed target in cancer immune therapy. The parties are jointly pursuing a preclinical research program with respect to the identification and generation of Anticalin proteins that bind to a specific target. Roche has the ability to continue certain exclusivity rights for up to an additional 5 years following the end of the research program. Both Roche and the Company will participate in a joint research committee in connection with this agreement. Following the research program, Roche will be responsible for subsequent pre-clinical and clinical development of any product developed through the research plan and will have worldwide commercialization rights to any such product.

Under an amendment to the Roche Agreement entered effective May 31, 2017, the initial period for the research program extends until January 1, 2018 and Roche has the option to extend this period until up to August 31, 2018.

Roche has paid $6.5 million of an upfront payment for the research collaboration. Additionally, Roche will pay Pieris for research services provided by Pieris in conjunction with the research program. Roche will also pay Pieris certain development and sales milestones as they are achieved.

Pieris recorded $0.8 million and $1.8 million in revenue, respectively, for the three months ended June 30, 2017 and the six months ended June, 30, 2017, related to the recognition of the upfront payment associated with the portion of the research collaboration as well as the value of research services provided by Pieris in connection with the ongoing research program. For the three months ended June 30, 2016 and the six months ended June 30, 2016, Pieris recorded $1.1 million and $2.3 million in revenue, related to the recognition of the upfront payment associated with the research collaboration. As of June 30, 2017, and June 30, 2016, deferred revenue, related to Roche collaboration, is $2.7 million and $5.1 million, respectively.

The Company identified the research and commercial licenses, performance of R&D services, and participation in the joint research committee as deliverables under the Roche Agreement. For revenue recognition purposes, management determined there are two units of accounting at inception of the agreement representing (i) the research and commercial licenses and the performance of R&D services, and (ii) the participation in the joint research committee. The consideration received has been allocated to the units of accounting and will be recognized on a proportional performance basis as the activities are conducted over the life of the arrangement.

In addition to the upfront payment, related to the Roche Agreement, the Company is eligible to receive research, development, and sales milestone payments up to approximately $424.6 million, plus royalties on future sales of any commercial products. The total potential milestones are categorized as follows: development milestones—$295.5 million; and sales milestones of $125.3 million. Management has determined that the development milestones are not substantive as they do not relate solely to past performance of the Company and the Company’s involvement in the achievement is limited to progress reports and other updates. Non-substantive milestones will be recognized when achieved to the extent the Company has no remaining performance obligations under the arrangement.

Les Laboratoires Servier and Institut de Recherches Internationales Servier

On January 4, 2017, Pieris entered into a License and Collaboration Agreement (“Servier Collaboration Agreement”), and Non-Exclusive Anticalin Platform Technology Agreement (the “License Agreement” and together with the Servier Collaboration Agreement, the “Servier Agreements”) with Les Laboratoires Servier and Institut de Recherches Internationales Servier (collectively “Servier”) pursuant to which Pieris and Servier will initially pursue five bispecific therapeutic programs, led by the PRS-332 program (the “Lead Product”), a PD-1-targeting bispecific checkpoint inhibitor. Pieris and Servier will jointly develop PRS-332 and split commercial rights geographically, with Pieris retaining all commercial rights in the United States and Servier having commercial rights in the rest of the world. Each party is responsible for an agreed upon percentage of shared costs, as set forth in the budget for the joint development plan, and as further discussed below.

Four additional committed programs have been defined, which may combine antibodies from the Servier portfolio with one or more Anticalin proteins based on Pieris’ proprietary platform to generate innovative immuno-oncology bispecific drug candidates (“Collaboration Products”). The collaboration may be expanded by up to three additional therapeutic programs. Pieris has the option to co-develop and retain commercial rights in the United States for up to three programs beyond PRS-332 (“Co-Development Collaboration Products”), while Servier will be responsible for development and commercialization of the other programs worldwide (“Servier Worldwide Collaboration Products”). Each party is responsible for an agreed upon percentage of shared costs, as set forth in the budget for the collaboration plan, and further discussed below.

Co-Development Collaboration Products may be jointly developed, according to a collaboration plan, through marketing approval from the U.S. Food and Drug Administration (“FDA”) or European Medicines Agency (“EMA”). Servier Worldwide Collaboration Products may be jointly developed, according to a collaboration plan, through specified preclinical activities, at which point Servier becomes responsible for further development of the collaboration product.

At inception, Servier was granted the following licenses: (i) development license for the Lead Product, (ii) commercial license for the Lead Product, (iii) individual research licenses for each of the four Collaboration Products, and (iv) individual non-exclusive platform technology licenses for each of the Lead Product and four Collaboration Products. Upon achievement of certain development activities, specified by the collaboration for each Servier Collaboration Agreement, Servier will be granted a development license and a commercial license. For the Lead Product and Co-Development Collaboration Products, the licenses granted are with respect to the entire world except for the United States. For Servier Worldwide Collaboration Products, the licenses granted are with respect to the entire world.

The Servier Agreements will be managed on an overall basis by a joint executive committee (“JEC”) formed by an equal number of members from the Company and Servier. Decisions by the JEC will be made by consensus, however, in the event of a disagreement, each party will have final-decision making authority as it relates to the applicable territory in which such party has commercialization rights for the applicable product. In addition to the JEC, the Collaboration Agreement requires the participation of both parties on: (i) a Joint Steering Committee (“JSC”), (ii) a Joint Development Committee (“JDC”), (iii) a Joint Intellectual Property Committee (“JIPC”), and (iv) a Joint Research Committee (“JRC”). The responsibilities of these committees vary, depending on the stage of development and commercialization of the Lead Product and each of the Collaboration Products.

For the Lead Product and Co-Development Collaboration Products, Pieris and Servier are responsible for an agreed upon percent of the shared costs required to develop the products through commercialization. In the event that Pieris fails to exercise their option to co-develop the Co-Development Collaboration Products, and Servier has the right to continue with development alone.

Under the Servier Agreements, the Company received an upfront, non-refundable payment of € 30.0 million (approximately $32.0 million). In addition, the Company is eligible to receive research, development, commercial, and sales milestone payments. The total potential milestones are categorized as follows: research, development, and commercial milestones – up to € 569.0 million; and sales milestones – up to € 515.0 million. In addition, Pieris will be entitled to receive tiered royalties up to low double digits on the sales of commercialized products in the Servier territories.

The initial research collaboration term, as it relates to the Lead Product and Collaboration Products, shall continue for three years from the effective date, and may be mutually extended for two one-year terms consecutively applied. The term of the Servier Agreements ends upon the expiration of all Servier’s payment obligations under the respective Agreement

The term of the Servier Agreement ends upon the expiration of all of Servier’s payment obligations under such Servier Collaboration Agreement. The Servier Collaboration Agreements may be terminated by Servier for convenience beginning 12 months after their effective date upon 180 days’ notice. The Servier Collaboration Agreements may also be terminated by Servier or Pieris for material breach upon 90 days’ or 120 days’ notice of a material breach, with respect to the Servier Collaboration Agreement and License Agreement, respectively, provided that the applicable party has not cured such breach by the applicable 90-day or 120-day permitted cure period, and dispute resolution procedures specified in the applicable Servier Collaboration Agreement have been followed. The Servier Collaboration Agreements may also be terminated due to the other party’s insolvency or for a safety issue and may in certain instances be terminated on a product-by-product and/or country-by-country basis. The License Agreement will terminate upon termination of the Servier Collaboration Agreement, on a product-by-product and/or country-by-country basis.

The Company accounted for the Servier Agreements as a multiple element arrangement under ASC 605-25. The arrangement with Servier contains the following initial deliverables: (i) five non-exclusive platform technology licenses, (ii) development license for the Lead Product, (iii) commercial license for the Lead Product, (iv) research and development services for the Lead Product, (v) participation on each of the committees, (vi) four research licenses for Collaboration Products, and (vii) research and development services for the Collaboration Products. Additionally, as the development and commercial licenses on the four Collaboration Products may be granted at discount in the future, the Company determined such discounts be included as an element of the arrangement at inception.

Management considered whether any of the deliverables could be considered separate units of accounting. The Company determined the licenses granted, at arrangement inception, did not have standalone value from the research and development services to be provided for the Lead Product and Collaboration Products, over the term of the Servier Agreements, due to the specific nature of the intellectual property and knowledge required to perform the research and development services. The Company determined that the participation on the various committees did have standalone value from the delivered licenses as the services could be performed by an outside party.

As a result, management concluded there are ten units of accounting at inception of the agreement: (i) combined unit of accounting representing a non-exclusive platform technology license, commercial license, development license and research and development services for the Lead Product, (ii) four units of accounting each representing a combined non-exclusive platform technology license, research license, and research and development services for each Collaboration Product (iii) one unit of accounting representing the participation of the various governance committees, and (iv) four units of accounting representing the discounts on the development and commercial licenses granted for the Collaboration Products upon the achievement of specified preclinical activities.

The Company determined that neither VSOE nor TPE is available for any of the units of accounting identified at arrangement inception. Accordingly, the selling price of each unit of accounting was developed using BESP. The Company developed its best estimate of selling price for licenses by applying a risk adjusted, net present value, estimate of future potential cash flows approach, which included the cost of obtaining research and development services at arm’s length from a third-party provider, as well as internal full time equivalent costs to support these services.

The Company developed the BESP for committee participation by using management’s best estimate of the anticipated participation hours multiplied by a market rate for comparable participants.

The Company developed the BESP for the discounts granted on the licenses by probability weighting multiple cash flow scenarios using the income approach.

Allocable arrangement consideration at inception is comprised of the upfront fee of € 30.0 million (approximately $32.0 million) and was allocated among the separate units of accounting using the relative selling price method.

The amounts allocated to the combined unit of accounting for the Lead Product and four units of accounting for the four Collaboration Products will be recognized on a proportional performance basis as the activities are conducted over the life of the arrangement. The term of the performance at inception of the agreement for the Lead Product and each of the Co-Developed Collaboration Products may be through approval of certain regulatory bodies; a period which could be many years. The term of the performance at inception of the agreement for each of the other two Servier Worldwide Collaboration Products is approximately two to three years. The amounts allocated to the participation on each of the committees will be recognized ratably over the anticipated performance period over the entirety of the arrangement with Servier. The amounts allocated to the discounts of the development and commercial licenses granted in the future will be recognized upon delivery of each of the licenses assuming no other performance obligations.

Additionally, the Company evaluated payments required to be made between both parties as a result of the shared development costs of the Lead Product and Co-Development Collaboration Products. The Company will classify payments made as a reduction of revenue and will classify payments received as revenue, in the period they are earned.

Under the Servier Agreements the Company is eligible to receive various research, development, commercial, and sales milestones. Management determined certain research development and commercial milestones, which may be received under the Servier Agreements, are substantive when the Company is involved in the development and commercialization of the applicable product. Payments related to the achievement of such milestones, if any, will be recognized as revenue when the milestone is achieved. Total potential substantive research, development and commercial milestones are up to € 163.0 million. Research, development, and commercial milestones are deemed non-substantive if they are based solely on the performance of another party. Non-substantive milestones will be treated as contingent revenue and will be recognized when achieved, to the extent the Company has no remaining performance obligations under the arrangement. Milestone payments earned upon the achievement of sales events will be recognized when earned.

The Company will recognize royalty revenue in the period of sale for the related product(s), based on the underlying contract terms, provided that the reported sales are reliably measurable and the Company has no remaining performance obligations, assuming all other revenue recognition criteria are met.

Pieris recorded $0.4 million and $0.7 million in revenue, respectively, for the three months ended June 30, 2017 and the six months ended June 30, 2017, respectively, with respect to the Servier Agreements which includes recognition of the upfront payment received and reimbursement for research and development expenses. No revenue was recorded during the three and six months ended June 30, 2016. As of June 30, 2017, there is $3.5 million and $30.1 million of deferred revenue and non-current deferred revenue, respectively, related to the Company’s collaboration with Servier.

ASKA Pharmaceutical Co. Ltd.

On February 27, 2017 the Company entered into an Exclusive Option Agreement (the “ASKA Agreement”) with ASKA Pharmaceutical Co., Ltd. (“ASKA”) to grant ASKA an option to acquire (1) a non-exclusive license to certain intellectual property rights associated with the Pieris’ Anticalin platform (“Licensed Platform IP”) and (2) an exclusive license to certain intellectual property rights specifically related to Pieris’ PRS-080 Anticalin protein (“Licensed Product IP”) in order to develop, manufacture, import, sale, export, and offer for sale and export any pharmaceutical formulation containing PRS-080, the Company’s pegylated Anticalin protein targeting hepcidin (“Licensed Product”) in Japan and certain other Asian territories (“Licensed Territory”).

ASKA has paid $2.75 million of an upfront option payment. Pieris is obliged to use commercially reasonable efforts to complete the Phase IIa Study for PRS-080 and to submit to ASKA, in writing, the final results of the study when available. Upon receipt, ASKA will have 60 days to evaluate the results of the Phase IIa Study (“Evaluation Period”). ASKA agreed to notify Pieris, in writing, of its decision to exercise its option to acquire rights to the Licensed Product. In consideration of the licenses granted as part of the Agreement, ASKA will pay an additional license fee. If the Phase IIa Study meets the applicable success criteria and ASKA fails to provide notification that it will exercise its option, ASKA shall pay the Company an additional fee within thirty days of the end of the Evaluation Period (the “Break-Up Fee”). If ASKA exercises the option, ASKA and the Company will enter into a separate definitive arrangement governing the future development and commercialization activities.

Pieris has an obligation to use all reasonable commercial efforts to complete the Phase IIa Study for the Licensed Product and to submit to ASKA, in writing, the final results of the Phase IIa study. The completed Phase IIa Study represents a deliverable under the arrangement. As the arrangement only contains one deliverable, there is only one unit of accounting to be considered at the inception of the contract. The total allocable arrangement consideration at inception is $2.75 million and this is allocated to the single unit of accounting. The Company noted that while the completion of the Phase IIa trial requires the completion of a number of actions, the finalization of the data and evaluation of results is of such significance that the value of the Phase IIa study results is realized at this point. As a result, the Company will recognize revenue for this unit of accounting upon delivery of the Phase IIa Study Results to ASKA. Therefore, no revenue in connection with this arrangement was recognized for the three and six months ended June 30, 2017. As of June 30, 2017, there is $2.93 million of non-current deferred revenue related to the Company’s option agreement with ASKA.

AstraZeneca AB

On May 2, 2017, Pieris entered into a License and Collaboration Agreement (“AstraZeneca Collaboration Agreement”), and a Non-Exclusive Anticalin Platform Technology License Agreement (the “License Agreement” and together with the AstraZeneca Collaboration Agreement, the “AstraZeneca Agreements”) with AstraZeneca AB (“AstraZeneca”), which became effective on June 10, 2017, following expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. Under the AstraZeneca Agreements the parties will advance several novel inhaled Anticalin proteins.

In addition to the Company’s lead inhaled drug candidate, PRS-060 (the “AstraZeneca Lead Product”), Pieris and AstraZeneca will also collaborate to progress four additional novel Anticalin proteins against undisclosed targets for respiratory diseases (the “AstraZeneca Collaboration Products” and together with the AstraZeneca Lead Product, the “AstraZeneca Products”). Pieris will be responsible for advancing the AstraZeneca Lead Product into the Phase I trial, with the associated costs funded by AstraZeneca. The parties will collaborate thereafter to conduct a Phase IIa clinical trial in asthma patients, with AstraZeneca continuing to fund development costs. After completion of the Phase IIa trial, Pieris has the option to co-develop the Lead Product and also has the option to co-commercialize the AstraZeneca Lead Product in the United States. For the four AstraZeneca Collaboration Products, Pieris will be responsible for the initial discovery of the novel Anticalin proteins, after which AstraZeneca will take the lead on continued development. Pieris has the option to co-develop two of these four AstraZeneca Collaboration Products beginning at a pre-defined preclinical stage and would also have the option to co-commercialize these two programs in the United States, while AstraZeneca will be responsible for development and commercialization of the other programs worldwide.

The term of the AstraZeneca Agreement ends upon the expiration of all of AstraZeneca’s payment obligations under such AstraZeneca Agreement. The AstraZeneca Collaboration Agreement may be terminated by AstraZeneca in its entirety for convenience beginning 12 months after its effective date upon 90 days’ notice or, if Pieris has obtained marketing approval for the marketing and sale of a product, 180 days’ notice. Each program may be terminated at AstraZeneca’s option; if any program is terminated by AstraZeneca, Pieris will have full rights to such program. The AstraZeneca Collaboration Agreement may also be terminated by AstraZeneca or Pieris for material breach upon 180 days’ notice of a material breach (or 30 days with respect to payment breach), provided that the applicable party has not cured such breach by the permitted cure period (including an additional 180 days if the breach is not susceptible to cure during the initial 180-day period) and dispute resolution procedures specified in the applicable AstraZeneca Agreement have been followed. The AstraZeneca Collaboration Agreement may also be terminated due to the other party’s insolvency and may in certain instances be terminated on a product-by-product and/or country-by-country basis. Each party may also terminate the agreement if the other party challenges the validity of patents related to certain intellectual property licensed under the AstraZeneca Agreement, subject to certain exceptions for infringement suits, acquisitions and newly-acquired licenses. The License Agreement will terminate upon termination of the AstraZeneca Collaboration Agreement, on a product-by-product and/or country-by-country basis.

At inception, AstraZeneca is granted the following licenses: (i) research and development license for the AstraZeneca Lead Product, (ii) commercial license for the AstraZeneca Lead Product, (iii) individual research licenses for each of the four AstraZeneca Collaboration Products, (iv) individual commercial licenses for each of the four AstraZeneca Collaboration Products, and (v) individual non-exclusive platform technology licenses for the AstraZeneca Lead Product and the four AstraZeneca Collaboration Products. AstraZeneca will be granted individual development licenses for each of the four AstraZeneca Collaboration Products upon completion of the initial discovery of Anticalin proteins.

The collaboration will be managed on an overall basis by a joint steering committee (“JSC”) formed by an equal number of representatives from the Company and AstraZeneca. In addition to the JSC, the AstraZeneca Collaboration Agreement also requires each party to designate an Alliance Manager to facilitate communication and coordination of the Parties activities under that AstraZeneca Agreement, as well as requires participation of both parties on: (i) a Joint Development Committee and (ii) a Commercialization Committee. The responsibilities of these committees vary, depending on the stage of development and commercialization of each Product.

Under the AstraZeneca Agreements, the Company received an upfront, non-refundable payment of $45 million. In addition, the Company will receive payments to conduct a Phase I trial for the Lead Product. The Company is also eligible to receive research, development, commercial, sales milestone payments, and royalty payments. The total potential milestones are categorized as follows: research, development, and commercial milestones – up to $1.1 billion; and sales milestones – up to $1.0 billion. The Company may receive tiered royalties on sales of potential products commercialized by AstraZeneca and for co-developed products, gross margin share on worldwide sales equal dependent on Pieris’ level of committed investment.

The Company accounted for the AstraZeneca Agreements, as a multiple element arrangement under ASC 605-25. The arrangement with AstraZeneca contains the following initial deliverables: (i) five non-exclusive platform technology licenses, (ii) research and development license for the AstraZeneca Lead Product, (iii) commercial license for the AstraZeneca Lead Product, (iv) development and manufacturing services for the AstraZeneca Lead Product, (v) research services related to the AstraZeneca Lead Product, (vi) participation on each of the committees, (vii) four research licenses for the AstraZeneca Collaboration Products, (viii) four development licenses for the AstraZeneca Collaboration Products (ix) four commercial licenses for the AstraZeneca Collaboration Products, and (x) research services for the AstraZeneca Collaboration Products.

Management considered whether any of the deliverables could be considered separate units of accounting. The Company determined that the licenses granted for the AstraZeneca Lead Product at the inception of the arrangement did not have standalone value from the research services related to the Lead Product and the licenses granted for the AstraZeneca Collaboration Products did not have standalone value from the research services for the AstraZeneca Collaboration Products, due to the specific nature of the intellectual property and knowledge required to perform the services. The Company determined that the licenses granted at the inception of the arrangement did have standalone value from the development and manufacturing services for the AstraZeneca Lead Product and also determined that the participation on the various committees had standalone value as the development and manufacturing services and committee service could be performed by an outside party.

As a result, management concluded that there were seven units of accounting at the inception of the AstraZeneca Agreements: (i) combined unit of accounting representing a non-exclusive platform technology license, research and development license, and commercial licenses for the Lead Product and research services for the AstraZeneca Lead Product, (ii) development and manufacturing services for the AstraZeneca Lead Product, (iii) committee participation, (iv-vii) four units of accounting representing a combined non-exclusive platform technology license, research, development and commercial licenses, and research services for each AstraZeneca Collaboration Product.

The Company determined that neither VSOE nor TPE is available for any of the units of accounting identified at the inception of the arrangement. Accordingly, the selling price of each unit of accounting was developed using management’s BESP. The Company developed the BESP for licenses and corresponding research services by applying a risk adjusted, net present value, estimate of future potential cash flow approach, which included the cost of obtaining research services at arm’s length from a third-party provider, as well as internal full time equivalent costs to support these services. The Company developed the BESP for development and manufacturing services for the AstraZeneca Lead Product using estimated internal and external costs to be incurred.

The Company developed the BESP for committee participation by using management’s best estimate of the anticipated participation hours multiplied by a market rate for comparable participants.

Allocable arrangement consideration at inception is comprised of the upfront fee of $45.0 million and the estimated development and manufacturing services to be reimbursed by AstraZeneca for the Lead Product of $8.2 million. The aggregate allocable consideration of $53.2 million is allocated among the separate units of accounting using the relative selling price method.

The amounts allocated to the combined unit of accounting for the AstraZeneca Lead Product will be recognized on a proportional performance basis as the activities are conducted over the life of the arrangement. The amounts allocated to the development and manufacturing services for the Lead Product will be recognized on a proportional performance basis over the estimated term of development through Phase IIa trial. The amounts allocated to the participation on each of the committees will be recognized on a straight-line basis over the expected term of development of the AstraZeneca Lead Product and the AstraZeneca Collaboration Products. The term of performance at the inception of the arrangement is approximately five years. The amounts allocated to the combined units of accounting for the Astra Zeneca Collaboration Product will be recognized upon delivery of each individual development license, assuming all other revenue recognition criteria have been met.

Additionally, the Company evaluated payments required to be made between both parties as a result of the shared development costs of the AstraZeneca Lead Product and the two AstraZeneca Collaboration Products for which Pieris has a co-development option. The Company will classify payments made as a reduction of revenue and will classify payments received as revenue, in the period they are earned.

Under the AstraZeneca Agreements the Company is eligible to receive various research, development, commercial, and sales milestones. Management determined certain of the research, development, and commercial milestones that may be received under the AstraZeneca Agreements are substantive when the Company is involved in the development and commercialization of the applicable AstraZeneca Products. Payment related to achievement of such milestones, if any, will be recognized as revenue when the milestone is achieved. Total potential substantive development milestones range from $72.2 million to $611.4 million, dependent on the Company’s decision, on a product-by-product basis, whether to co-develop the AstraZeneca Lead Product and AstraZeneca Collaboration Products. Research, development, and commercial, and sales milestones are deemed non-substantive if they are based solely on the performance of another party. Non-substantive milestones will be treated as contingent revenue and will be recognized when achieved to the extent the Company has no

remaining performance obligations under the arrangement. Total potential non-substantive research, development, and commercial milestones range from $366.2 million to $1.0 billion. The Company may receive lower research, development, and commercial, milestones if the Company chooses to co-develop the Lead Product and/or AstraZeneca Collaboration Products, depending on the level of co-development investment. Total potential sales milestones are up to $1.0 billion and will be recognized when earned, assuming all other revenue recognition revenue criteria have been met.

The Company will recognize royalty and gross margin share revenue in the period of sale of the related AstraZeneca Product, based on the underlying contract terms, provided that the reported sales are reliably measurable and the Company has no remaining performance obligations, assuming all other revenue recognition criteria are met.

Pieris recorded $0.6 million in revenue for the three and six months ended June 30, 2017, with respect to the AstraZeneca Agreements, which includes recognition of the upfront payment received and reimbursement for Phase I trial costs. As of June 30, 2017, there is $19 million and $27.4 million of deferred revenue and non-current deferred revenue, respectively, related to the AstraZeneca Agreements.

4. Income taxes

During the three months ended June 30, 2017 and the six months ended June 30, 2017 the Company recorded income tax expenses of $0.8 million and $0.8 million, respectively, representing an effective tax rate of (4.71%). The income tax expense is related the Company´s Australian jurisdiction, net of loss carryforwards resulting from taxable income from the AstraZeneca Agreements.

5. Net Loss per Share

Basic net loss per share was determined by dividing net loss by the weighted average shares outstanding during the period. Diluted net loss per share was determined by dividing net loss by diluted weighted average shares outstanding. Diluted weighted average shares reflect the dilutive effect, if any, of common stock options based on the treasury stock method.

For all financial statement periods presented the number of basic and diluted weighted average shares outstanding remained the same as an increase in the number of shares of common stock equivalents for the periods presented would be antidilutive.

For the six months ended June 30, 2017 and 2016, approximately 3.6 million and 5.9 million weighted average shares, subject to stock options and warrants, respectively, as calculated using the treasury stock method, were excluded from the calculation of diluted weighted average shares outstanding as their effect was antidilutive.

6. Fair Value Measurement

ASC Topic 820 Fair Value Measurement defines fair value as the price that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants at the measurement date. Pieris applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

Level 1 inputs are quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 utilizes quoted market prices in markets that are not active, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency.

Level 3 inputs are unobservable inputs for the asset or liability in which there is little, if any, market activity for the asset or liability at the measurement date.

For the periods presented, in these interim financial statements, Pieris has no cash equivalents and debt instruments as of each balance sheet date presented.

All other current assets and current liabilities on our consolidated balance sheets approximate their respective carrying amounts.

7. Accrued expenses

The Company has recorded the following accrued expenses as of June 30, 2017 and December 31, 2016, respectively:

8. Stock-based compensation

2014 Stock Plan

Pieris granted 88,853 and 1,157,734 options to employees, consultants, and directors under its 2014 employee, director, and consultant equity incentive plan, (the “2014 Plan”) during the three months ended six months ended June 30, 2016, respectively. The 2014 Plan was terminated on June 28, 2016 when the Company adopted its 2016 employee, director and consultant equity incentive plan, (the “2016 Plan”). Therefore, no options were granted for the three and six months ended June 30, 2017 under the 2014 Plan.

2016 Stock Plan

In June 2016, the Company adopted the 2016 Plan which provides for the grant of stock options, restricted and unrestricted stock awards, and other stock-based awards to employees of the Company, non-employee directors of the Company, and certain other consultants performing services for the Company as designated by the Compensation Committee of the Board of Directors or the Board of Directors. The vesting periods of equity incentives issued under the 2016 Plan are determined by the Compensation Committee of the Company’s Board of Directors, with stock options generally vesting over a four-year period.

The Company granted 118,367 and 1,258,755 options to employees and directors under the 2016 Plan during the three months ended June 30, 2017 and the six months ended June 30, 2017, respectively. No options were granted under the 2016 Plan during the same periods or 2016. As of June 30, 2017, there were 2,094,670 shares available for future grant under the 2016 Plan. The shares available for future grant under the 2016 Plan include 217,530 shares which were forfeited under the 2016 Plan and 11,208 shares which were forfeited under the 2014 Plan. These forfeited shares are available for future issuance under the 2016 Plan.

Stock-based compensation expense was $0.6 million and $1.3 million for the three months ended June 30, 2017 and the six months ended June 30, 2017, respectively. For the three months ended June 30, 2016 and the six months ended June 30, 2016, stock based compensation expense was $0.6 million and $1.0 million, respectively.

Total stock-based compensation expense was recorded to operating expenses based upon the functional responsibilities of the individuals holding the respective options as follows:


	Three months ended June 30,				Six months ended June 30,
	2017		2016		2017		2016
Research and Development	$	190,819	$	175,498	$	357,430	$	301,939
General and administrative		369,059		436,347		954,640		678,290

Total stock-based compensation expense	$	559,878	$	611,845	$	1,312,070	$	980,229

There were an aggregate of 15,000 and 15,000 options exercised under the 2014 Plan during the three months ended June 30, 2017 and the six months ended June 30, 2017, respectively, for which the Company received $30,000 in cash. There were 74,462 and 74,462 options exercised under the 2016 Plan during the three months ended June 30, 2017 and the six months ended June 30, 2017, respectively, for which the Company received $147,950 in cash. No options were exercised during the 2016 periods.

The Company uses the Black-Scholes option pricing model to determine the estimated fair value for stock-based awards. Option-pricing models require the input of various subjective assumptions, including the option’s expected life, expected dividend yield, price volatility, risk free interest rate, and forfeitures of the underlying stock. Accordingly, the weighted-average fair value of the options granted was $2.08 and $1.39 for the three months ended June 30, 2017 and the six months ended June 30, 2017. The weighted-average fair value of the options granted was $1.09 and $1.01 for the three months ended June 30, 2016 and the six months ended June 30, 2016.

The calculation was based on the following assumptions:


	Three months ended June 30,						Six months ended June 30,
	2017			2016			2017			2016
Dividend yield		0.0	%		0.0	%		0.0	%		0.0	%
Expected volatility		75.13% - 78.89	%		75.12% - 75.53	%		75.09% - 78.89	%		75.12% - 76.00	%
Weighted average risk-free interest rate		1.87% - 1.99	%		1.13% - 1.49	%		1.87% - 2.16	%		1.13% - 1.61	%
Expected term		5.0 - 5.7 years			5.0 - 5.7 years			5.0 - 5.7 years			5.0 - 5.7 years

Option-pricing models require the input of various subjective assumptions, including the option’s expected life and the price volatility of the underlying stock. Pieris’ estimated expected stock price volatility is based on the average volatilities of other guideline companies in the same industry. Pieris’ expected term of options granted during the three and six months ended June 30, 2017 and 2016, respectively was derived using the SEC’s simplified method. The risk-free rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant.

The Company’s stock options have a maximum term of ten years from the date of grant. Stock options granted under the 2016 Plan may be either incentive stock options, or nonqualified stock options. The exercise price of stock options granted under the 2016 Plan must be at least equal to the fair market value of the common stock on the date of grant.

9. Common Stock

The Company has authorized 300,000,000 shares of common stock, $0.001 par value, per share, of which 43,840,909 shares were issued and outstanding as of June 30, 2017 and 43,058,827 shares were issued and outstanding as of December 31, 2016.

During the three and six months ended June 30, 2017, the Company issued an aggregate of 89,462 shares of common stock upon exercise of stock options, including stock options to purchase 50,000 shares of common stock exercised through net exercise provisions resulting in the issuance of 19,462 shares of common stock and stock options to purchase 70,000 shares of common stock exercised for cash, providing cash proceeds of $0.2 million.

During the three and six months ended June 30, 2017, the Company issued an aggregate of 692,620 shares of common stock due to warrant exercises. Net exercise of 89,330 warrants resulted in the issuance of 49,127 shares of common stock. Additionally, 643,493 were exercised resulting in cash proceeds of $1.3 million.

10. Private Placement

In June 2016, the Company entered into a securities purchase agreement (the “Securities Purchase Agreement”) for a private placement of the Company’s securities with a select group of institutional investors (the “2016 PIPE”). The 2016 PIPE sale transaction, by the Company, consisted of 8,188,804 units at a price of $2.015 per unit for gross proceeds, to the Company, of approximately $16.5 million. After deducting for placement agent fees and offering expenses, the aggregate net proceeds from the private placement was approximately $15.3 million.

As a result of the 2016 PIPE the number of common stock outstanding increased by 3,225,804 shares and the number of Series A Convertible Preferred Stock outstanding increased by 4,963 shares.

11. License and Transfer Agreement

On April 18, 2016, the Company entered into a license and transfer agreement (the “Original Agreement”) with Enumeral Biomedical Holdings, Inc. (“Enumeral”), pursuant to which the Company acquired a non-exclusive worldwide license to use specified patent rights and know-how owned by Enumeral to research, develop and market fusion protein. As contemplated by the terms of the Original Agreement, the Company entered into a definitive license and transfer agreement (the “Definitive Agreement”) with Enumeral on June 6, 2016, to expand the scope of the Company´s option to license additional antibodies from Enumeral. Under the Definitive Agreement, Enumeral has granted Pieris options to license two additional undisclosed Enumeral antibodies (each, a “Subsequent Option”). The Subsequent Options expired unexercised on May 31, 2017.

Under the terms of the Original Agreement, the Company agreed to pay Enumeral an upfront license fee of $250,000 upon signing in April 2016 and subsequently elected to pay a $750,000 maintenance fee in May 2016. All amounts paid related to the Agreement have been expensed as research and development expense as incurred. The Company incurred $1.0 million in upfront fees for the three and six months ended June 30, 2016. No amounts were incurred for the three and six-month period end June 30, 2017.

12. Liquidity and Going Concern

The Company believes its cash of $50.3 million as of June 30, 2017 and the receipt of $45 million, in July 2017, from AstraZeneca, will be sufficient to fund the Company’s current operating plan for at least twelve months from date of filing. The Company may need to raise additional funds in order to execute the current operating plan in the future. There can be no assurance that the Company will be able to obtain future additional debt, equity financing, or generate product revenue or revenues from collaborative partners, on terms acceptable to the Company, on a timely basis or at all. The failure of the Company to obtain sufficient funds on acceptable terms when needed could have a material adverse effect on the Company’s business, results of operations, and financial condition.

13. Recent Accounting Pronouncements

Standards not yet adopted

In May 2014, the FASB issued Accounting Standard Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). Subsequently, the FASB also issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606) , which adjusted the effective date of ASU 2014-09; ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) , which amends the principal-versus-agent implementation guidance and illustrations in ASU 2014-09; ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing , which clarifies identifying performance obligation and licensing implementation guidance and illustrations in ASU 2014-09; and ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients , which addresses implementation issues and is intended to reduce the cost and complexity of applying the new revenue standard in ASU 2014-09 (collectively, the “Revenue ASUs”).

The Revenue ASUs provide an accounting standard for a single comprehensive model for use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. The accounting standard is effective for interim and annual periods beginning after December 15, 2017, with an option to early adopt for interim and annual periods beginning after December 15, 2016. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (the full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the modified retrospective method). We currently anticipate adoption of the new standard effective January 1, 2018 under the modified retrospective method. The Company is in the process of determining the impact of the Revenue Recognition ASUs on its financial statements.

In February 2016, the FASB issued ASU No. 2016-02, ASU 2016-02 Leases (Topic 842)(“ASU 2016-02”) . Under the amendments in ASU 2016-02 lessees will be required to recognize (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term for all leases (with the exception of short-term leases) at the commencement date. This guidance is effective for fiscal years beginning after December 15, 2019 including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the potential impact the adoption of this standard will have on its financial statements and related disclosures. The Company is in the process of determining the impact of the lease ASU with respect to its financial statements.

In May 2017, the FASB issued ASU No. 2017-09, Compensation – Stock compensation (Topic 718)(“ASU 2017-09”) . The amendments in this update provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The amendments in this ASU 2017-09 are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted. The Company is currently evaluating the potential impact the adoption of this standard will have on its financial statements and related disclosures.

Pieris has considered other recent accounting pronouncements and concluded that they are either not applicable to the business, or that the effect is not expected to be material to the unaudited condensed consolidated financial statements as a result of future adoption.

Company Overview

We are a clinical-stage biopharmaceutical company that discovers and develops Anticalin ^® protein-based drugs to target validated disease pathways in a unique and transformative way. Our pipeline includes immuno-oncology multi-specifics tailored for the tumor micro-environment, an inhaled Anticalin to treat uncontrolled asthma and a half-life-optimized Anticalin to treat anemia. Proprietary to Pieris, Anticalin proteins are a novel class of low molecular-weight therapeutic proteins derived from lipocalins, which are naturally occurring low-molecular weight human proteins typically found in blood plasma and other bodily fluids.

Each of our development programs focus on the following:

•

300-Series oncology drug candidates are multispecific Anticalin ^® -based proteins designed to engage immunomodulatory targets and consist of a variety of multifunctional biotherapeutics that genetically link antibody with one or more Anticalin proteins, thereby constituting a multispecific protein;

•

PRS-343 our lead immune-oncology program is a 4-1BB/HER2 targeting bispecific, comprised of an anti-HER2- antibody genetically linked to a 4-1BB-targeting Anticalin protein, in which tumor-targeted drug clustering mediated by HER2 expressed on certain solid tumors is intended to drive tumor localized T cell activation for patient unresponsive to current standard of care.

•

PRS-332 is a bispecific Anticalin-antibody fusion protein comprising an anti-PD-1 antibody genetically fused to an Anticalin protein targeting an undisclosed checkpoint target. In order to improve on existing PD-1 therapies, we are developing PRS-332 with the intent to simultaneously block PD-1 and another immune checkpoint co-expressed on exhausted T cells.

•

In connection with our efforts to develop multispecific Anticalin ^® -based proteins designed to engage immunomodulatory targets, during the second quarter, the Company entered into a License and Transfer Agreement with Sichuan Kelun-Biotech Biopharmaceutical Co. Ltd. (“Kelun”). Under that Agreement, Kelun has granted to the Company a non-exclusive worldwide license (with the right to sublicense) under certain intellectual property owned or controlled by Kelun to research, develop, manufacture, and commercialize bi- and multi- specific fusion proteins that include a monoclonal antibody developed by Kelun specific for an undisclosed target and one or more Anticalin proteins.

•

PRS-080 is an Anticalin protein that binds to hepcidin, a natural regulator of iron in the blood. PRS-080 has been designed to target hepcidin for the treatment of functional iron deficiency in anemic patients with chronic kidney disease particularly in end-stage renal disease patients requiring dialysis.

•

PRS-060 is an inhaled Anticalin that binds to the IL receptor alpha, thereby inhibiting the signaling of IL-4 and IL-13, two cytokines, small proteins mediating signaling between cells within the human body), known to be key mediators in the inflammatory cascade that causes asthma and other inflammatory diseases.

Our key programs are in varying stages:

•

PRS-343—We filed an investigational new drug application (“IND”) for our lead immuno-oncology drug candidate, PRS-343, and FDA has accepted that IND. The Company is diligently engaged with its clinical trial sites toward initiation of patient dosing in a Phase I study in HER2-positive solid tumors.

•

Other PRS-300 Series—We are conducting activities relating to lead candidate identification, lead candidate optimization, preclinical evaluation, or IND filing preparation on several of our other 300-Series (immuno-oncology) candidate drugs, including the lead product in our collaboration with Servier, PRS-332, and have initiated activities for two of the Servier collaboration programs beyond PRS-332.

•

PRS-080—We completed a Phase Ia single-ascending dose clinical trial with PRS-080 in healthy volunteers in 2015. Based on the data we obtained in the Phase I clinical trial, we initiated a Phase Ib clinical study in CKD5 patients requiring hemodialysis. We completed that Phase Ib study and presented the results in June 2017, which reflected that intravenous administration of PRS-080 was both safe and well-tolerated at all doses, and resulted in a profound decrease in free hepcidin within one hour after infusion, followed by robust mobilization of serum iron, with dose-proportional increases in both the level and duration of serum iron concentration and transferrin saturation following treatment. The Company filed separate clinical trial applications (“CTA”s) with the German and Czech Republic regulatory authorities to conduct a multi-dose Phase IIa trial for PRS-080 in FID anemia patients in a randomized placebo-controlled trial at doses up to 8 mg per kg body weight. Pending timely regulatory approvals, the Company intends to initiate enrollment of patients for this study in the third quarter of this year. ASKA has the option, following completion of this trial, to obtain an exclusive license to develop and commercialize PRS-080 in Japan, South Korea and certain other Asian markets (excluding China).

•

PRS-060— In collaboration with AstraZeneca, Pieris plans, as trial sponsor, to initiate and dose healthy subjects in the fourth quarter of 2017 in a single ascending dose trial followed by a multi-ascending dose trial under a clinical trial notification to the Therapeutic Goods Administration in Australia. The dosing of the first subject will trigger a milestone payment of $12.5 million by AstraZeneca to Pieris.

Our core Anticalin ^® technology and platform was developed in Germany, and we have partnership arrangements with major multi-national pharmaceutical companies headquartered in the U.S., Europe and Japan and with regional pharmaceutical companies headquartered in India. These include existing agreements with Daiichi Sankyo, and Sanofi, pursuant to which our Anticalin platform has consistently achieved its development milestones. Furthermore, we established a collaboration with Roche in December 2015, a collaboration with Servier in January 2017, and a collaboration with AstraZeneca in May 2017. We have discovery and preclinical collaboration and service agreements with both academic institutions and private firms in Australia.

Since inception, we have devoted nearly all of our efforts and resources to our research and development activities and have incurred significant net losses. For the three months ended June 30, 2017 and the six months ended June 30, 2017 we reported a net loss of $10.1 million and $18.1 million, respectively. For the three months ended June 30, 2016 and the six months ended June 30, 2016 we reported a net loss of $5.9 million and $10.0 million, respectively. As of June 30, 2017, we have an accumulated deficit of $120.7 million.

We expect to continue incurring substantial losses for the next several years as we continue to develop our clinical and preclinical drug candidates and programs. Our operating expenses are comprised of research and development expenses and general and administrative expenses.

We have not generated any revenues from product sales to date, and we do not expect to generate revenues from product sales for at least the next several years. Our revenues for the periods presented were primarily from license and collaboration agreements with our partners.

A significant portion of our operations are conducted in countries other than the United States. Since we conduct our business in U.S. dollars, our main exposure, if any, results from changes in the exchange rates between the euro and the U.S. dollar. All assets and liabilities denominated in euros are translated into U.S. dollars at the exchange rate on the balance sheet date. Revenues and expenses are translated at the average rate during the period. Equity transactions are translated using historical exchange rates. Adjustments resulting from translating foreign currency financial statements into U.S. dollars are included in accumulated other comprehensive loss. We may incur negative foreign currency translation changes as a result of changes in currency exchange rates.

Financial Operations Overview

The following discussion summarizes the key factors our management believes are necessary for an understanding of our consolidated financial statements.

Revenues

We have not generated any revenues from product sales to date, and we do not expect to generate revenues from product sales for the foreseeable future. Our revenues for the last two years have been primarily from the license and collaboration agreements with AstraZeneca, Servier, Roche and Daiichi Sankyo.

The revenues from our collaborations historically have been comprised primarily of upfront payments, research and development services and, to a lesser extent, milestone payments. We recognized revenues from upfront payments under these agreements in accordance with multiple-element arrangement guidance as we have determined that the delivered licenses to which the payments related did not have standalone value from the other elements of the arrangement. Research service revenue is recognized when the costs are incurred and the services have been performed. For revenues from research, development, commercial, and sales milestone payments, if the milestones are deemed substantive and the milestone payments are nonrefundable, such amounts are recognized entirely upon successful accomplishment of the milestones, assuming all other revenue recognition criteria are met. Milestones that are not considered substantive are accounted for as contingent revenue and will be recognized when achieved to the extent the Company has no remaining performance obligations under the arrangement. Revenues from sales milestone payments are accounted for as royalties and are recorded as revenue upon achievement of the milestone, assuming all other revenue recognition criteria are met. Royalty payments are recognized in revenues based on the timing of royalty payments earned in accordance with the agreements, which typically is the period when the relevant sales occur, assuming all other revenue recognition criteria are met.

We expect our revenues for the next several years to consist of upfront and milestone payments, reimbursable development costs and expenses, research funding and other payments from strategic collaborations we currently have or may establish in the future.

Research and Development Expenses

The process of researching and developing drugs for human use is lengthy, unpredictable, and subject to many risks. We expect to continue incurring substantial expenses for the next several years as we continue to develop our clinical and preclinical drug candidates and programs. We are unable with any certainty to estimate either the costs or the timelines in which those costs will be incurred. Our current development plans focus on the following activities: Our PRS 300-series, which is a franchise currently comprised of the PRS-343 and PRS-332 program, PRS-080 and PRS-060. These programs consume a large proportion of our current, as well as projected, resources.

Our research and development costs include costs that are directly attributable to the creation of certain of our Anticalin ^® drug candidates and are comprised of:

•

internal recurring costs, such as labor and fringe benefits, materials and supplies, facilities and maintenance costs; and

•

fees paid to external parties who provide us with contract services, consulting services, such as preclinical testing, manufacturing and related testing, and clinical trial activities.

General and Administrative Expenses

General and administrative expenses consist primarily of payroll, employee benefits, equity compensation, and other personnel-related costs associated with executive, administrative and other support staff. Other significant general and administrative expenses include costs associated with professional fees for accounting, auditing, insurance costs, consulting, and legal services.

•

The $0.8 million increase in revenues from collaboration arrangements in the three months ended June 30, 2017 compared to the three months ended June 30, 2016 relates to the recognition of revenue under our collaboration with Servier, which commenced in January 2017, and revenue under our collaboration with AstraZeneca, which commenced in May 2017, offset by slightly lower revenues from upfront payments under our collaboration with Roche due to less full-time equivalents used in Q2 2017 compared to Q2 2016 .

•

The slight decrease in revenues from research and development services in the three months ended June 30, 2017 compared to the three months ended June 30, 2016 relates to less research and development services being provided to Roche pursuant to the Roche Agreement.

The following table provides a comparison of revenues for six months ended June 30, 2017 and 2016, respectively (in thousands):


	Six months ended June 30, 2017		Six months ended June 30, 2016		$ Change			% Change

•

The $1.0 million increase in revenues from collaboration arrangements in the six months ended June 30, 2017 compared to the six months ended June 30, 2016 relates to the recognition of revenue under our collaboration with Servier, which commenced in January 2017, and revenue under our collaboration with AstraZeneca, which commenced in May 2017, offset by slightly lower revenues from upfront payments under our collaboration with Roche due to less full-time equivalents used in the first half of 2017 compared to the first half of 2016 .

•

The $0.1 million decrease in revenues from research and development services in the six months ended June 30, 2017 compared to the six months ended June 30, 2016 relates to less research and development services being provided to Roche pursuant to the Roche Agreement.

Research and Development expenses

The following table provides a comparison of the research and development expenses for our drug candidates and projects for the three months ended June 30, 2017 and 2016, respectively in thousands):


	Three months ended June 30,
	2017		2016		$-Change			%-Change
PRS-300 series	$	633	$	1,084	$	(451	)		(42	%)
PRS-060		1,298		566		732			129	%
PRS-080		501		223		278			125	%
Non-core research and development activities		2,964		2,627		337			13	%

Total	$	5,396	$	4,500	$	896			20	%

Total research and development expenses were $5.4 million for the three months ended June 30, 2017 as compared to $4.5 million for the three months ended June 30, 2016.

The increase in total research and development expenses in the three months ended June 30, 2017 compared to the three months ended June 30, 2016 is primarily due to:

•

the $0.5 million decrease for our PRS-300 series is due to a $0.5 million decrease in CMC and preclinical costs in our PRS343 program and a decrease of $0.1 million in general lab supplies. These amounts are offset by an increase of $0.1 million in clinical costs period over period;

•

the $0.7 million increase for PRS-060 is mainly due to $0.4 million of license fees for the successful close of our license and collaboration agreement with AstraZeneca and $0.1 million in other consulting expenses. In the three months ended June 30, 2016 we recorded a $0.4 million tax credit in connection with our PRS-060 program and no such tax credit was recorded in the 2017 period. In addition, we recognized an increase of $0.1 million in clinical costs. These amounts are offset by a decrease of $0.3 million in lower CMC costs;

•

the $0.3 million increase for PRS-080 is mainly due to clinical costs related to the preparation of the Phase IIa study which we will initiate in the third quarter of 2017;

•

the $0.3 million increase in non-core research and development activities is mainly due to a $0.3 million increase in payroll expenses, including bonus payments, an increase of $0.2 million for preclinical and CMC costs, and a $0.2 million increase for general lab costs. Other costs, such as recruiting, travel and legal costs, increased by $0.6 million. These increases were offset by a $1.0 million license fee payment to Enumeral in the second quarter of 2016.

The following table provides a comparison of the research and development expenses for our drug candidates and projects for the six months ended June 30, 2017 and 2016, respectively (in thousands):


	Six months ended June 30,
	2017		2016		$-Change		%-Change
PRS-300 series	$	2,611	$	2,177	$	434		20	%
PRS-060		2,144		906		1,238		137	%
PRS-080		904		572		332		58	%
Non-core research and development activities		5,127		4,505		622		14	%

Total	$	10,786	$	8,160	$	2,626		32	%

Total research and development expenses were $10.8 million for the six months ended June 30, 2017 as compared to $8.2 million for the six months ended June 30, 2016.

This increase in total research and development expenses in the six months ended June 30, 2017 compared to the six months ended June 30, 2016 is primarily due to:

•

the $0.4 million increase in our PRS-300 series is due to a $0.1 million increase in salary costs as well as a $0.3 million license fee payment to Technische Universitat Munchen (“TUM”) in connection with the Servier agreement. In addition, preclinical and clinical cost increased by $0.6 million offset by lower CMC expenses of $0.6 million;

•

the $1.2 million increase for PRS-060 is mainly due to $0.4 million in license fees for the successful close of our license and collaboration agreement with AstraZeneca and $0.1 million in other consulting fees. In addition, we recorded $0.5

million R&D tax credit, in connection with our PRS-060 program, in the first half 2016 and no tax credit was recorded in the 2017 period. CMC costs, clinical costs, and costs for toxicity studies increased by $0.5 million. These amounts are offset by a decrease of $0.3 million in preclinical costs;

•

the $0.3 million increase for PRS-080 is due to higher clinical costs related to the Phase IIb study, where the clinical part of the study was completed in the first quarter of 2017 as well as clinical costs related to the preparation of the Phase IIa study which we will initiate in the third quarter of 2017;

•

the $0.6 million increase in non-core research and development activities is mainly due to a $0.5 million increase in higher personnel expenses including bonus and stock compensation, an increase of $0.3 million in preclinical and CMC costs as well as additional $0.2 million in general lab supplies. Other costs such like travel, legal, maintenance and recruiting expenses increased by $0.9 million. These amounts are offset by $1.0 million in license fees to Enumeral we paid in the second quarter of 2016 and a $0.3 million license fee to TUM in connection with the Roche agreement in the first quarter of 2016.

General and Administrative expenses

General and administrative expenses were $4.3 million for the three months ended June 30, 2017 compared to $2.4 million for the three months ended June 30, 2016. This $1.9 million increase is mainly due to $1.8 million in transaction fees for the successful close of our license and collaboration agreement with AstraZeneca. Period-over-period, personnel related costs increased by $0.1 million, professional services increased by $0.1 million recruiting and other costs increased by $0.2 million and legal fees decreased by $0.3 million.

General and administrative expenses were $8.3 million for the six months ended June 30, 2017 compared to $4.3 million for the six months ended June 30, 2016. This $4.0 million increase is due to $1.8 million in transaction fees for our license and collaboration agreement with AstraZeneca, in addition to the increase of professional fees by $1.1 million personnel costs by $0.8 million, recruiting, travel and other fees increased by $0.6 million and offset by a $0.3 million decrease of legal fees.

Non-operating expense (income), net

Our non-operating expense was $1.4 million for three months ended June 30, 2017 as compared to $0.1 million of non-operating expense for the three months ended June 30, 2016. This increase in expense is mainly a result of net foreign currency transaction losses, including foreign currency revaluations of monetary assets.

Our non-operating expense was $1.4 million for six months ended June 30, 2017 as compared to a net non-operating income of $0.1 million for the six months ended June 30, 2016. This increase in expense is mainly a result of net foreign currency transaction losses, including foreign currency revaluations of monetary assets.

Income tax expense

Income tax expense was $0.8 million for three months ended June 30, 2017 as compared to zero income tax expenses for the three months ended June 30, 2016. The increase in income tax expense is related our Australian jurisdiction, net of loss carryforwards resulting from taxable income from the AstraZeneca agreement.

Income tax expense was $0.8 million for six months ended June 30, 2017 as compared to zero income tax expenses for the six months ended June 30, 2016. The increase in income tax expense is related our Australian jurisdiction, net of loss carryforwards resulting from taxable income from the AstraZeneca agreement.

Liquidity and Capital Resources

Through June 30, 2017, we have funded our operations with $231.8 million of cash, obtained from the following main sources: $119.4 million from sales of equity; $91.7 million in total payments received under license and collaboration agreements, including $14.0 million for research and development services costs received from our collaboration partners; $14.2 million from government grants and $6.5 million from loans.

As of June 30, 2017, we had a total of $50.3 million in cash. In July 2017, we collected $45.0 million of up-front fees from our collaboration with Astra Zeneca.

We have experienced operating losses since our inception and had a total accumulated deficit of $120.7 million as of June 30, 2017. We expect to incur additional costs and will require additional future capital. We have incurred losses in nearly every period since inception including the three and six months ended June 30, 2017. These losses have primarily resulted in significant cash used in operations. Due to the upfront payments received from Servier and the option payment received from ASKA during the six months ended June 30, 2017 offset by our net losses for the period, our net cash provided by operating activities was $19.3 million as of

June 30, 2017. We have several research and development programs underway in varying stages of development and we expect they will continue to require increasing amounts of cash for development, conducting clinical trials, and testing and manufacturing of product material. As we continue to conduct these activities necessary to pursue governmental regulatory approval of our 300-Series programs PRS-343 and PRS-332, and PRS-080 and PRS-060, and our other product candidates, we expect cash necessary to fund operations will increase significantly over the next several years.

In June 2016, we entered into a securities purchase agreement for a private placement with a select group of institutional investors. The private placement, referred to as the 2016 PIPE, consisted of the sale of 8,188,804 units at a price of $2.015 per unit for gross proceeds to us of approximately $16.5 million. After deducting for placement agent fees and offering expenses, the aggregate net proceeds from the 2016 PIPE was approximately $15.3 million.

In August 2016, our shelf registration statement in the amount of $100 million was declared effective by the SEC. This registration allows us to offer for sale various unspecified classes of equity and debt securities. As circumstances warrant, we may issue debt and/or equity securities from time to time on an opportunistic basis, dependent upon market conditions and available pricing. We make no assurance that we can issue and sell such securities on acceptable terms or at all.

In January 2017, we entered into a License and Collaboration Agreement and a Non-Exclusive Anticalin Platform Technology License Agreement with Les Laboratories Servier and Institut de Recherches Internationales Servier (collectively, “Servier”). Under the agreements, we received an upfront payment of $32.3 million. The total development, regulatory and sales-based milestone payment to us could exceed $1.8 billion over the life of the collaboration.

In May 2017, we entered into a License and Collaboration Agreement (the “Collaboration Agreement”) and a Non-Exclusive Anticalin ^® Platform Technology License Agreement (the “License Agreement” and together with the Collaboration Agreement, the “Agreements”) with AstraZeneca AB (“AstraZeneca”). Under the agreements, the Company will receive $57.5 million in up-front and near-term milestone payments, including $45 million of up-front payments and $12.5 million for the initiation of the PRS-060 Phase I trial. We may receive research, development, commercial and sales milestone payments up to approximately $2.1 billion.

We will need to obtain additional funding in order to continue our operations and pursue our business plans. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce, or eliminate our research and development programs or future commercialization efforts.

In the first half of 2017 we issued an aggregate of 89,462 shares of common stock upon exercise of stock options, including stock options to purchase 50,000 shares of common stock exercised through net exercise provisions resulting in the issuance of 19,462 shares of common stock and stock options to purchase 70,000 shares of common stock exercised for cash, providing cash proceeds of $0.2 million. In addition, we issued an aggregate of 692,620 shares of common stock upon exercise of warrants, including warrants to purchase 89,330 shares of common stock exercised through net exercise provisions resulting in the issuance of 49,127 shares of common stock and warrants to purchase 643,493 shares of common stock exercised for cash, providing cash proceeds of $1.3 million.

We expect that our existing cash and cash equivalents will enable us to fund our operations and capital expenditure requirements for at least the next twelve months. Our requirements for additional capital will depend on many factors, including the following:

•

the scope, rate of progress, results, timing and cost of our clinical studies, preclinical testing and other related activities;

•

the cost of manufacturing clinical supplies, and establishing commercial supplies, of our drug candidates and any products that we may develop;

•

the number and characteristics of drug candidates that we pursue;

•

the cost, timing and outcomes of regulatory approvals;

•

the cost and timing of establishing sales, marketing and distribution capabilities;

•

the terms and timing of any collaborative, licensing and other arrangements that we may establish;

•

the timing, receipt and amount of sales, profit sharing or royalties, if any, from our potential products;

•

the cost of preparing, filing, prosecuting, defending, and enforcing any patent claims and other intellectual property rights; and

•

the extent to which we acquire or invest in businesses, products or technologies, although we currently have no commitments or agreements relating to any of these types of transactions.

We cannot be sure that future funding will be available to us on acceptable terms, or adequate enough at all. Due to the often volatile nature of the financial markets, equity and debt financing may be difficult to obtain. In addition, any unfavorable development or delay in the progress of our 300-Series programs PRS-343and PRS-332, and PRS-080 and PRS-060 could have a material adverse impact on our ability to raise additional capital.

We may seek to raise any necessary additional capital through a combination of private or public equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements and other marketing and distribution arrangements. To the extent that we raise additional capital through marketing and distribution arrangements or other collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our drug candidates, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. If we raise additional capital through private or public equity offerings, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our stockholders’ rights. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. We believe that our existing cash as of June 30, 2017 will be sufficient to enable us to continue as a going concern through at least twelve months from the day of filing.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Critical Accounting Policies and Estimates

Refer to Part II, Item 7, “Critical Accounting Policies and Estimates” of our Annual Report on Form 10-K for the fiscal year ended on December 31, 2016 for a discussion of our critical accounting policies and estimates. There were no significant changes to our Critical Accounting Policies and Estimates for the six months ended June 30, 2017.

Recently Issued Accounting Pronouncements

We review new accounting standards to determine the expected financial impact, if any, that the adoption of each such standard will have. For the recently issued accounting standards that we believe may have an impact on our consolidated financial statements, see “Note 13—Recently Issued Accounting Pronouncements” in our consolidated financial statements.

Emerging Growth Company and Smaller Reporting Company Status

The Jumpstart Our Business Startups Act of 2012, or the JOBS Act, establishes a class of company called an “emerging growth company,” which generally is a company whose initial public offering was completed after December 8, 2011 and had total annual gross revenues of less than $1 billion during its most recently completed fiscal year. Additionally, Section 12b-2 of the Exchange Act establishes a class of company called a “smaller reporting company,” which generally is a company with a public float of less than $75 million as of the last business day of its most recently completed second fiscal quarter or, if such public float is $0, had annual revenues of less than $50 million during the most recently completed fiscal year for which audited financial statements are available. We currently qualify as both an emerging growth company and a smaller reporting company.

As an emerging growth company and a smaller reporting company, we are eligible to take advantage of certain exemptions from various reporting requirements that are not available to public reporting companies that do not qualify for those classifications, including without limitation the following:

•

An emerging growth company is exempt from any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and financial statements, commonly known as an “auditor discussion and analysis.”

•

An emerging growth company is not required to hold a nonbinding advisory stockholder vote on executive compensation or any golden parachute payments not previously approved by stockholders.

•

Neither an emerging growth company nor a smaller reporting company is required to comply with the requirement of auditor attestation of management’s assessment of internal control over financial reporting, which is required for other public reporting companies by Section 404 of the Sarbanes-Oxley Act.

•

A company that is either an emerging growth company or a smaller reporting company is eligible for reduced disclosure obligations regarding executive compensation in its periodic and annual reports, including without limitation exemption from the requirement to provide a compensation discussion and analysis describing compensation practices and procedures.

•

A company that is either an emerging growth company or a smaller reporting company is eligible for reduced financial statement disclosure in registration statements, which must include two years of audited financial statements rather than the three years of audited financial statements that are required for other public reporting companies. Smaller reporting companies are also eligible to provide such reduced financial statement disclosure in annual reports on Form 10-K.

For as long as we continue to be an emerging growth company and/or a smaller reporting company, we expect that we will take advantage of the reduced disclosure obligations available to us as a result of those respective classifications. We will remain an emerging growth company until the earlier of (i) December 31, 2019, the last day of the fiscal year following the fifth anniversary of the date of the first sale of our common stock pursuant to an effective registration statement under the Securities Act; (ii) the last day of the fiscal year in which we have total annual gross revenues of $1 billion or more; (iii) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under applicable SEC rules. We expect that we will remain an emerging growth company for the foreseeable future, but cannot retain our emerging growth company status indefinitely and will no longer qualify as an emerging growth company on or before December 31, 2019. We will remain a smaller reporting company until we have a public float of $75 million or more as of the last business day of our most recently completed second fiscal quarter, and we could retain our smaller reporting company status indefinitely depending on the size of our public float.

Emerging growth companies may elect to take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to take advantage of the benefits of this extended transition period. Our financial statements may therefore not be comparable to those of companies that comply with such new or revised accounting standards.

Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management is responsible for establishing and maintaining “disclosure controls and procedures”, as such term is defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, as well as for establishing and maintaining “adequate internal control over financial reporting” as such term is defined in Rule 13a-15(f) under the Exchange Act. The Company’s system of internal controls over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the consolidated financial statements in accordance with generally accepted accounting principles.

Because of the inherent limitations surrounding internal controls over financial reporting, our disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Additionally, in designing disclosure controls and procedures, our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any disclosure controls and procedures also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Our management, under the supervision of and with the participation of the Chief Executive Officer and Acting Chief Financial Officer, assessed the effectiveness of the Company’s internal control over financial reporting and disclosure controls and procedures as of June 30, 2017. In making this assessment, management used the updated criteria set forth in 2013 by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework.

Based on our assessment under the COSO Internal Control-Integrated Framework, management believes that, as of June 30, 2017, our internal control over financial reporting was effective.

We have concluded that the financial statements and other financial information included in this Quarterly Report on Form 10-Q, fairly represent in all material respects our financial condition, results of operations, and cash flows as of, and for, the periods presented.

Changes in Internal Control over Financial Reporting

There are no changes in our internal control over financial reporting identified in connection with the evaluation of such internal control required by Rules 13a-15(d) and 15d-15(d) under the Exchange Act that occurred during the quarter ended June 30, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1.

Legal Proceedings

Claims and lawsuits are filed against our Company from time to time. Although the results of pending claims are always uncertain, we believe that we have adequate reserves or adequate “insurance coverage” in respect of these claims, but no assurance can be given as to the sufficiency of such reserves or insurance coverage in the event of any unfavorable outcome resulting from these actions.

Item 1A.

Risk Factors

There have been no material changes from the risk factors previously disclosed in Part I, Item 1A (Risk Factors) of our Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

Other Information

On August 9, 2017, the Company appointed Allan Reine, 42, as Senior Vice President and Chief Financial Officer. Prior to joining the Company, Dr. Reine served from August 2012 through August 2017 as a portfolio manager of Lombard Odier Asset Management, where he managed a healthcare portfolio focused on biotechnology and pharmaceutical companies. Before joining Lombard Odier, Dr. Reine served as a healthcare portfolio manager at various funds from 2003 through 2012, including Citi Principal Strategies, SAC Capital, Trivium Capital and Alexandra Investment Management. Dr. Reine began his career in 2001 at CIBC World Markets where he worked in both biotechnology investment banking and biotechnology equity research. Dr. Reine received his M.D. from the University of Toronto, and his Bachelor of Science in Statistical Sciences from the University of Western Ontario.

The Company and Dr. Reine entered into an employment agreement, dated August 9, 2017 (the “Employment Agreement”). Pursuant to the Employment Agreement, Dr. Reine will receive an initial annual base salary of $375,000. Dr. Reine is also eligible to receive an annual discretionary bonus award of up to 40% of his then-current base salary. The bonus award, if any, will be determined by the Company’s Board of Directors or a committee thereof.

In connection with his appointment, Dr. Reine received a stock option to purchase 450,000 shares of the Company’s common stock, par value $0.001 per share (“Common Stock”), at an exercise price equal to the closing price of the Common Stock on the NASDAQ Global Select Market on August 9, 2017, the date of grant of the stock option. The stock option will have a ten-year term and will vest over approximately four years, subject to continued service with the Company through the applicable vesting dates, and will vest as to 25% of the shares underlying the stock option on the first anniversary of the commencement of Dr. Reine’s employment with the Company and as to 75% on a quarterly basis beginning on the last day of the next calendar quarter after Dr. Reine’s start date. This stock option was granted outside of the Company’s 2016 Employee, Director and Consultant Equity Plan as an inducement material to Dr. Reine’s acceptance of employment in accordance with NASDAQ Listing Rule 5635(c)(4). Dr. Reine also received an option to purchase up to 50,000 shares of the Company’s common stock, at an exercise price equal to the closing price of the Common Stock on the NASDAQ Global Select Market on August 9, 2017, the date of grant of the stock option. This option will have a ten-year term and will vest as to 25% of the shares underlying the stock option on the first anniversary of the date that the Board of Directors or a committee thereof certifies the achievement of certain objectives and as to 75% on a quarterly basis over the following three years. The objectives will be mutually agreed by Dr. Reine and the Company on or about the date Dr. Reine commences his employment.

Under the terms of the Employment Agreement, Dr. Reine’s employment with the Company may be terminated at any time, with or without cause and without any prior notice, by either Dr. Reine or the Company. If the Company terminates Dr. Reine’s employment is terminated by the Company without cause (as defined in the Employment Agreement) or Dr. Reine resigns for good reason (as defined in the Employment Agreement), the vesting of seventy-five percent (75%) of the unvested portion of the stock options will accelerate. Furthermore, if Dr. Reine’s employment is terminated by the Company without cause or Dr. Reine resigns for good reason, he will be entitled to receive continuation of his then-current base salary for a period of six months, which will be payable in periodic

installments in accordance with the Company’s payroll practices and he will be entitled to receive (a) an amount equal to twelve months of salary plus the target bonus amount for the year of termination and (b) continuation of COBRA health insurance premiums at the Company’s then-normal rate of contribution for twelve months. If, in connection with a change of control of the Company, the Company terminates Dr. Reine’s employment without cause or Dr. Reine terminates his employment for good reason, he will be entitled to receive (a) an amount equal to twelve months of salary plus the target bonus amount for the year of termination and (b) continuation of COBRA health insurance premiums at the Company’s then-normal rate of contribution for twelve months. In the case of such a termination in connection with a change in control, outstanding equity awards held by Dr. Reine shall automatically become vested and if, applicable, exercisable, except as otherwise provided in the Employment Agreement, and all forfeiture restrictions shall immediately lapse. As a condition of employment, Dr. Reine has entered into a Non-Competition and Non-Solicitation Agreement and a Confidentiality and Inventions Agreement with the Company. Dr. Reine will also enter into an Indemnification Agreement with the Company relating to his employment.

There are no transactions to which the Company is a party and in which Dr. Reine has a material interest that are required to be disclosed under Item 404(a) of Regulation S-K. Dr. Reine has not previously held any positions with the Company and has no family relationship with any directors or executive officers of the Company.

4.3.2.1. Collaboration Product Reservation List . Prior to the Execution Date, AstraZeneca and Pieris have agreed a list of [***] ([***]) initial Targets set out at Exhibit 4.3.2.1, from which the Targets for the Collaboration Products must be selected (the “ Reservation List ”). The Reservation List may be updated in part from time-to-time by AstraZeneca (but not more frequently than removing [***] and replacing it with another [***] every [***]) by replacing [***] on the Reservation List with [***] from outside the Reservation List. The Reservation List shall never include more than [***] Targets and shall include a decreasing number of Targets over the Collaboration Term as set forth in Section 4.3.2.4 . All information disclosed by AstraZeneca to Pieris in respect of proposed Targets shall be AstraZeneca Confidential Information.

4.3.2.2. Reservation List Process and Restrictions . AstraZeneca’s ability to place any Target on the Reservation List shall be subject to (i) any Third Party contractual restrictions on Pieris or its Affiliates evidenced by written documentation provided to AstraZeneca (for example a redacted agreement including such contractual restriction which may be disclosed by Pieris to AZ’s counsel on a counsel- to- counsel basis), and (ii) Pieris’ ongoing internal programs with respect to such Target, as follows:

(a) Updates to the Reservation List . For updates to the Reservation as permitted by Section 4.3.2.1 , AstraZeneca shall provide Pieris with the name of [***] that it wishes to add to the Reservation List and the name of [***] that it wishes to remove from the Reservation List. Within [***] of receipt Pieris shall confirm that such [***] is added to the Reservation List or shall notify AstraZeneca that (i) such [***] is subject to Third Party contractual restrictions on Pieris or its Affiliates that prevents Pieris from granting rights to AstraZeneca in accordance with this Agreement, or (ii) Pieris has already initiated an internal program (i.e., [***]) with respect to such [***]; any such [***] shall not be included in the Reservation List, the [***] proposed to be removed from the Reservation List shall not be removed, and AstraZeneca shall, until the start of [***] to update the Reservation List as set forth in Section 4.3.2.1 , be entitled to nominate [***] and the [***] that it wishes to remove from the Reservation List, at which time the process described in this Section 4.3.2.2 shall repeat.

Within [***] of receipt of such notice, AstraZeneca shall inform Pieris whether it wishes to make such target its next Designated Target. If AstraZeneca fails to inform Pieris within such [***] period that it wishes to make such target its next Designated Target and Pieris [***] with respect to such target, then AstraZeneca shall not be allowed to add such target to the Reservation List in the future as contemplated in Section 4.3.2.2(a) above. All information disclosed by Pieris to AstraZeneca in respect of such targets shall be Pieris’ Confidential Information and shall be used by AstraZeneca only for the purpose of considering whether it wishes to make such target a Designated Target.

4.3.2.3. Field Limitation on Reservation List . The Targets that AstraZeneca proposes for the Reservation list shall be limited to Targets that are [***] in the Respiratory Field. Upon addition of a Target to the Reservation List, AstraZeneca shall include the initial Indication within the Respiratory Field related to such Target. Pieris has the right to reject any Target proposed to be added to the Reservation List that does not meet the requirement of this Section 4.3.2.3 on the basis of objective criteria which criteria will be disclosed to AstraZeneca if Pieris rejects a Target on this basis.

4.3.2.4. Designation of Collaboration Product Targets from the Reservation List . AstraZeneca shall nominate Targets from the Reservation List to become a Target for one of the four Collaboration Product Development Plans to Research and Develop Collaboration Products (a “ Designated Targe t”) according to the following schedule:

(a) Within [***] ([***]) days of [***] ([***]) months after the Execution Date, AstraZeneca shall nominate one (1) Target from the Reservation List to become a Designated Target. Upon nomination, there shall be [***] ([***]) remaining Targets on the Reservation List.

(d) Within [***] ([***]) days of [***] ([***]) months after the Execution Date, AstraZeneca shall nominate the one additional Target from the Reservation List to become a Designated Target. Upon nomination, the Reservation List shall terminate and Pieris shall no longer be subject to any restrictions with respect to Targets that are on such list.

4.3.2.5. AZ Dev Product or CoDev Product Designation . At the time a Target is identified as a Designated Target, it shall also be designated as an AZ Dev Product or CoDev Product.

4.3.2.6. Right of First Refusal for Reservation List . In the event that Pieris receives a bona fide request from a Third Party to (co-) Research, (co-)Develop, (co-)Manufacture or (co-)Commercialize a Target that is on the Reservation List as of the date of receipt of such request, then notwithstanding the schedule set forth in Section 4.3.2.4 , AstraZeneca shall have [***] from the date that Pieris notifies AstraZeneca of such bona fide request to either (i) nominate such Target to become a Designated Target or (ii) remove such Target from the Reservation List. Any Target which as a result becomes a Designated Target shall be deemed to take the place of the Target which was next due to be designated in accordance with Section 4.3.2.4 .

4.3.2.7. Notification of Designated Target . AstraZeneca shall notify Pieris of nominated Designated Targets as set forth in Section 4.3.2.4 in writing and Pieris shall confirm receipt of such nomination within [***]. The Parties shall discuss in good faith whether such Designated Target shall be for a CoDev Product or a AZ Dev Product and the Designated Target shall be classified as for a CoDev Product or AZ Dev Product within [***] of Pieris’ confirmation of receipt of the Designated Target nomination. In case the Parties cannot agree on whether such Designated Target shall be for a CoDev Product or AZ Dev Product, then AstraZeneca shall have final decision making authority for the [***] Designated Target, and Pieris shall have final decision making authority for the [***] Designated Target. Notwithstanding the foregoing, [***] that become Designated Targets as described in Section 4.3.2.4 shall be classified as for a CoDev Product provided that [***].

Pieris shall notify AstraZeneca as soon as reasonably possible if Pieris becomes aware that the agreed budget is going to be exceeded. For avoidance of doubt, such costs shall be reimbursed by AstraZeneca as incurred by Pieris in accordance with its Accounting Standards. In case Pieris expects a cost overrun of more than [***] percent ([***]%) of the mutually agreed budget, Pieris shall inform AstraZeneca in writing before such cost above [***] percent ([***]%) overrun are incurred. AstraZeneca shall inform Pieris promptly whether it agrees to pay for such cost overrun above [***] percent ([***]%). For clarity, if AstraZeneca does not agree to pay for such cost overrun above [***] percent ([***]%), Pieris shall not be obligated to conduct the activities that would lead to such additional cost overrun above [***] percent ([***]%). In case AstraZeneca requests additional activities to be conducted by Pieris or a Third Party during such time, it shall also assume responsibility for all costs incurred in conducting such additional activities. Such Out-of-Pocket Costs and FTE Costs shall be reimbursed each Calendar Quarter within [***] ([***]) days of receipt by AstraZeneca of an invoice for such costs. AstraZeneca may request supporting documentation evidencing that such costs have been incurred and Pieris shall provide such information if requested. Should there be a dispute as to whether such costs have been incurred, the matter shall be addressed under the dispute resolution provisions in Section 15.1. In case any amount that has been paid by AstraZeneca is disputed and later shown not to have been incurred in accordance with this Agreement, AstraZeneca may credit such unjustified and paid amount against any future payments to Pieris under this Agreement. In the period between the Completion of the Phase 1 Study for the Lead Product and Pieris’ determination of whether it will exercise its Lead Product CoDev Option in accordance with Section 4.5.1 below AstraZeneca shall have sole responsibility for all costs for the further Research, Development, Manufacture (to the extent applicable) of the Lead Product (including Pieris’ Out-of-Pocket Costs and FTE Costs, to the extent that Pieris is assigned any activities under the then-current Lead Product Development Plan).

4.4.3.3. Concurrent with execution of the CoDev Product CoDev Option, Pieris shall select whether it wishes to [***] split the Development Costs associated with the continued Development and Manufacture of the CoDev Product (“ [***] ”) or whether it wishes to contribute [***] percent ([***]%) of the Development Costs associated with the continued Development and Manufacture of the CoDev Product (the “ [***] Split Option ”). Should the total budget for the updated Collaboration Product Development Plan as set forth in Section 4.5.2.2 exceed [***] dollars ($[***]), then Pieris may, in the alternative, elect to contribute [***] percent ([***]%) of the Development Costs associated with the continued Development and Manufacture of such CoDev Product up to a cap of [***] dollars ($[***]) (the “ [***] Cap Option ”).

4.4.3.4. AstraZeneca shall at all times be responsible for all costs associated with Commercialization of the CoDev Product. In the event that Pieris exercises it Co-Commercialization Option under Section 7.1 , AstraZeneca shall be responsible for [***] co-Commercializing the CoDev Product as set forth in Section 7.2 .

4.4.3.5. If Pieris exercises its Opt-Out Option with respect to a CoDev Product under Section 4.6 , then Pieris shall no longer be responsible for contributing to the Development Costs for such Product once the Opt-Out Option Notice is delivered to AstraZeneca.

4.4.4. Cap on Collaboration Product Development Costs Through Lead Candidate Stage . Notwithstanding Section 4.4.2.1 and Section 4.4.3.1 , Pieris shall not be required to expend more than [***] Dollars ($[***]) (including, for avoidance of doubt, all Pieris Out-of-Pocket and FTE Costs) during the Collaboration Term in the course of Researching and Developing all four (4) Collaboration Products through Lead Candidate stage (for avoidance of doubt, including costs expended in attempting to Develop any [***] in accordance with Section 4.3.3.2 ). Such amount includes the Pieris FTE Costs that would be dedicated to such Research and Development Activities in addition to Out-of-Pocket Costs directed to such work. In case no Lead Candidate has been identified after Pieris has expended the amount of resources set forth in this Section 4.4.4 , the Parties shall discuss in good faith sharing of additional costs to be expended in order to identify a Lead Candidate for all four (4) Collaboration Products. Notwithstanding the foregoing, in case (i) no hits have been identified within [***] ([***]) [***] of the start of initial screening against a Designated Target, or (ii) no Lead Candidate has been identified within [***] ([***]) [***] of start of an optimization campaign for identified hits, in each case despite Pieris using its reasonable efforts, then Pieris shall not be obligated to expend any further resources on identifying a Lead Candidate for such Designated Target.

9.4. Additional Developmental Milestone Payment Terms.

9.4.1. Skipped Developmental Milestone Events and Payments . If any of the above Developmental Milestone Events are skipped (i.e. a later Developmental Milestone Payment is payable before an earlier Developmental Milestone Payment), or if Marketing Approval is achieved in any jurisdiction with respect to a Product without all of the preceding milestone payments applicable to such Product having been achieved, then the skipped Developmental Milestone Event will be deemed to have been achieved upon the achievement of the subsequent milestone or upon Marketing Approval and the corresponding Developmental Milestone Payment(s) shall then become due, as applicable. For avoidance of doubt, this Section 9.3.6 also applies to the Candidate Drug Investment Decision and the Candidate Drug Investment Decision milestone payment shall be due in full (even if a Product does not meet the Candidate Drug criteria set forth in the applicable Development Plan) if AstraZeneca decides to select such Product for Candidate Drug Investment Decision.

9.4.2. Satisfaction of Technical Candidate Drug Criteria Without [***] . For each Collaboration Product, in the event that such Product meets the Technical Candidate Drug Criteria established in accordance with Section 3.2.5.2(c)(iii) and included in the Collaboration Product Development Plan but

Page 82 of 163

AstraZeneca nonetheless determines not to select such Product for [***], then the [***] milestone shall be due and payable to Pieris but shall be [***] Dollars ($[***]). AstraZeneca’s decision not to select such Product (i.e., either the Lead Candidate or any Back-Up Hit of such Product) meeting the Technical Candidate Drug Criteria for [***] within [***] ([***]) months after the Lead Candidate or any Back-Up Hit of such Product first met such Technical Candidate Drug Criteria, shall be deemed a termination of such Product by AstraZeneca for convenience under Section 14.2.3 . If within such [***] ([***]) month period AstraZeneca does make a [***] with respect to the Product (i.e., either the Lead Candidate or any Back-Up Hit of such Product), AstraZeneca shall pay the applicable [***] milestone less [***] Dollars ($[***]) already paid pursuant to the first sentence of this Section 9.4.2 . For avoidance of doubt, however, AstraZeneca must at all times continue to use Commercially Reasonable Efforts to Develop such Product. By way of example and for clarity, if AstraZeneca initially chooses not to make a [***] in order to generate more data regarding the Product and to reconsider, then the initial decision shall not be deemed a termination for convenience.

9.4.3. EU Milestones . The “MAA filing in the EU” milestone shall be deemed met with respect to each Product when AstraZeneca files an MAA with the EMA or when it files an MAA with any country of the European Union. The “First Commercial Sale in the EU” shall be deemed upon the First Commercial Sale of each Product in the European Union.

9.5. Sales Related Milestone Payments . As partial consideration for the rights granted hereunder regarding each Product, AstraZeneca shall make, on a Product-by-Product basis, the non-refundable, non-creditable, one-time payments (the “ Sales Milestone Payments ”) to Pieris based upon achievement upon the first achievement of the following Calendar Year cumulative Net Sales of each Product (the “ Sales Milestone Event ”) as set forth below within [***] days of the end of the Calendar Year where such Sales Milestone Event is achieved.

9.7.2. Reductions for Third Party Obligations . Subject to Section 9.7.3 below, in the event it would be reasonably necessary to obtain additional licenses to Patents of Third Parties that Cover the active pharmaceutical ingredient (“ API ”) of the Products, in order to Commercialize the API of any Product (but

Page 89 of 163

not, for example, the formulation or associated device, which shall solely be the responsibility of AstraZeneca) (“ Additional Third Party Licenses ”), AstraZeneca shall negotiate and obtain any such Additional Third Party Licenses but shall not be obligated to do so. AstraZeneca and Pieris shall [***] the costs under such Additional Third Party Licenses and Pieris’ [***] percent ([***]%) share of such costs shall be payable in the form of a reduction, on a country-by-country and Product-by-Product basis, of the Product Royalty that would otherwise be payable by AstraZeneca to Pieris. Pieris’ share of the total costs of such Additional Third Party License shall not reduce Pieris’ Royalty by more than [***] percent ([***]%) of the Product Royalty otherwise due to Pieris in any Calendar Quarter, provided that reductions to Royalty Payments under this Section 9.7.2 not exhausted in one Calendar Quarter may be carried forward to the next Calendar Quarter. For avoidance of doubt, nothing stated herein shall prevent Pieris from seeking licenses to any Intellectual Property Rights or Patent Rights from any Third Party as it deems necessary. Where Pieris is entitled to Gross Margin Payments rather than Product Royalties, Pieris’ [***] percent ([***]%) share of such costs shall be deducted from the Gross Margin Payments otherwise payable to Pieris. Pieris’ share of the total costs of such Additional Third Party License shall not reduce Pieris’ Gross Margin Payment by more than [***] percent ([***]%) of the Gross Margin Payment otherwise due to Pieris in any Calendar Quarter, provided that reductions to Gross Margin Payments under this Section 9.7.2 not exhausted in one Calendar Quarter may be carried forward to the next Calendar Quarter.

9.7.3. Payments to Third Parties in respect of Target IP and Platform IP. Notwithstanding Section 9.7.2 above, Pieris shall be responsible for all costs associated with any license from a Third Party where such license is reasonably necessary, because absent such license, the practice of the Pieris Platform IP and the Pieris Platform Technology in accordance with this Agreement and the Platform Agreement would, in and of itself and irrespective of the Target relevant to such activities or the use of the Anticalin generated through the practice of such IP and Platform Technology, infringe a Patent owned or controlled by such Third Party. Notwithstanding Section 9.7.2 above, AstraZeneca shall be responsible for all costs associated with any license from a Third Party to a Patent that generically claims compositions of matter that are specific to the Target or methods of treatment involving the Target in the Field (excluding the [***] Grant-Back Field with respect to the Lead Product) where such license is reasonably necessary because absent such a license, AstraZeneca’s import, export, Manufacture, use, sale or offer for sale of an Anticalin directed to the applicable Designated Target (or the Lead Product Target, as applicable) would infringe such Third Party Patent. Neither AstraZeneca nor Pieris shall enter into any such license on behalf of the other without the other’s prior written consent which consent shall not be unreasonably withheld, conditioned or delayed.

Page 90 of 163

9.7.4. Reduction for Biosimilar Competition. If in any Calendar Quarter after entry of a Biosimilar(s) of a Product in a given country there has been a decline of the Net Sales of the applicable Product in such country of more than [***] percent ([***]%) of the Net Sales of such Product in such country achieved in the two consecutive Calendar Quarters immediately prior to such entry in such country, the Royalty Payment payable to Pieris for such Product in such country shall be reduced by [***] percent ([***]%) of the amount otherwise payable hereunder as and from such Calendar Quarter. Notwithstanding the foregoing, in the event of Biosimilar sales that are later enjoined by a court or otherwise halted (such as on the basis of Patent or Regulatory Exclusivity) and the price of the Product returns to the same level as was achieved immediately prior to entry of the Biosimilar, then royalties shall be restored to the level otherwise contemplated under this Agreement. For avoidance of doubt, there shall be no reduction of Gross Margin Payments in connection with this Section 9.7.4 .

9.7.5. Royalty Minimum . Notwithstanding the foregoing but subject to Section 9.7.3 , in no event will the Product Royalties due to Pieris in a Calendar Quarter be reduced by more than [***] percent ([***]%) of the amount that would otherwise be due hereunder.

9.8. Payment Terms.

9.8.1. Manner of Payment . All payments to be made by AstraZeneca hereunder will be made in Dollars by wire transfer to such bank account as Pieris may designate.

9.8.2. Reports and Royalty Payments . For as long as a Product Royalty or Gross Margin Payment is due to Pieris under this Agreement, AstraZeneca will furnish to Pieris a written report, within [***] ([***]) days after the end of each Calendar Quarter, showing in Dollars, the amount of Net Sales of Products and royalty due, or Gross Margin and Gross Margin Payment due for such Calendar Quarter, as applicable. Product Royalties and/or Gross Margin Payments consistent with the written report provided under this Section 9.8.2 for each Calendar Quarter will be due within [***] ([***]) days after the end of each Calendar Quarter. The report will include, at a minimum, the following information for the applicable Calendar Quarter, each listed by Product and by country of sale: (a) the number of units of each Product on which Product Royalty or Gross Margin Payment are owed to Pieris hereunder sold by AstraZeneca or its Affiliates or Sublicensees; (b) the gross amount received for such sales; (c) Net Sales for the Calendar Quarter and Year; (d) the Fully Burdened Manufacturing Cost for such Product; (e) deductions provided for in the definition of Net Sales; and (f) the Product Royalties, Gross Margin Payment, and Sales Milestone Payments owed to Pieris listed by category, as applicable. All such reports will be treated as Confidential Information of AstraZeneca.

Page 91 of 163

9.8.3. Records and Audits . AstraZeneca shall keep complete, true and accurate books and records in accordance with its Accounting Standards in relation to this Agreement, including in relation to Lead Product, AZ Dev Product and CoDev Product Development Costs and Net Sales, Fully Burdened Manufacturing Costs, Gross Margin Payments and Product Royalties. Pieris shall keep complete true and accurate books and records in accordance with Accounting Standards in relation to Lead Product and CoDev Product Development Costs. Each Party will keep such books and records for at least [***] ([***]) years following the Calendar Year to which they pertain. The other Party may, upon written request, cause an internationally-recognized independent accounting firm (the “ Auditor ”), which is reasonably acceptable to the audited Party, to inspect the relevant records of the audited Party and its Affiliates to verify the payments made or Costs incurred by the audited Party and the related reports, statements and books of accounts, as applicable. Before beginning its audit, the Auditor shall execute an undertaking acceptable to the audited Party by which the Auditor agrees to keep confidential all information reviewed during the audit. The Auditor shall have the right to disclose to the auditing Party only its conclusions regarding any payments owed under this Agreement. The audited Party and its Affiliates shall make their records available for inspection by the Auditor during regular business hours at such place or places where such records are customarily kept, upon receipt of reasonable advance notice from the auditing Party or the Auditor. The records shall be reviewed solely to verify the accuracy of the audited Party’s payment or Cost sharing obligations and compliance with the financial terms of this Agreement. Such inspection right shall not be exercised more than once in any Calendar Year and not more frequently than once with respect to records covering any specific period of time. In addition, the auditing Party shall only be entitled to audit the books and records of the audited Party from the [***] ([***]) Calendar Years prior to the Calendar Year in which the audit request is made. The auditing Party agrees to hold in strict confidence all information received and all information learned in the course of any audit or inspection, except to the extent necessary to enforce its rights under this Agreement or to the extent required to comply with any law, regulation or judicial order. The Auditor shall provide its audit report and basis for any determination to the audited Party at the time such report is provided to the auditing Party before it is considered final. In the event that the final result of the inspection reveals an undisputed underpayment or overpayment by either Party, the underpaid or overpaid amount shall be settled promptly. The auditing Party shall pay for such inspections, as well as its expenses associated with enforcing its rights with respect to any payments hereunder. In addition, if an underpayment of more than [***] percent ([***]%) of the total payments due hereunder for the applicable year is discovered, the fees and expenses charged by the Auditor shall be paid by the audited Party.

9.8.5. Taxes .

9.8.5.1. The royalties, milestones and other amounts payable by AstraZeneca to Pieris pursuant to this Agreement (“Payments”) shall not be reduced on account of taxes unless required by Applicable Laws.

AstraZeneca shall deduct or withhold from the Payments any taxes that it is required by Applicable Laws to deduct or withhold. If, however, Pieris is entitled under any applicable tax treaty to a reduction of rate of, or the elimination of, applicable withholding tax, it may deliver to AstraZeneca or the appropriate Governmental Authority (with the assistance of AstraZeneca to the extent that this is reasonably required and is expressly requested in writing) the prescribed forms necessary to reduce the applicable rate of withholding or to relieve AstraZeneca of its obligation to withhold tax, and AstraZeneca shall apply the reduced rate of withholding, or dispense with withholding, as the case may be, provided that AstraZeneca has received evidence, in a form reasonably satisfactory to AstraZeneca, of Pieris’ delivery of all applicable forms at least fifteen (15) Business Days prior to the time that the Payments are due. If AstraZeneca withholds any taxes from the Payments while Pieris is entitled under any applicable tax treaty to a reduction of the rate of, or the elimination of, applicable withholding tax, AstraZeneca shall cooperate with Pieris with respect to any documentation required by the appropriate Governmental Authority or reasonably requested by Pieris to secure a reduction of the rate of, or the elimination of, the applicable taxes withheld.

9.8.5.2. Notwithstanding anything to the contrary contained in this Agreement, the following shall apply with respect to Indirect Taxes: All payments are stated exclusive of Indirect Taxes. If any Indirect Taxes are chargeable in respect of any payments, AstraZeneca shall pay such Indirect Taxes at the applicable rate in respect of any such payments following the receipt, where applicable, of an Indirect Taxes invoice issued in the appropriate form by Pieris in respect of those payments, such Indirect Taxes to be payable on the due date of the payment of the

Page 93 of 163

payments to which such Indirect Taxes relate or at the time such Indirect Taxes are required to be collected by Pieris, in the case of payment of Indirect Taxes to Pieris. The Parties shall issue invoices for all goods and services supplied under this Agreement consistent with Indirect Tax requirements, and to the extent any invoice is not initially issued in an appropriate form, AstraZeneca shall promptly inform Pieris and shall cooperate with Pieris to provide such information or assistance as may be necessary to enable the issuance of such invoice consistent with Indirect Tax requirements.

9.8.6. Blocked Payments . In the event that, by reason of Applicable Law in any country, it becomes impossible or illegal for AstraZeneca to transfer, or have transferred on its behalf, payments owed to Pieris hereunder, AstraZeneca will promptly notify Pieris of the conditions preventing such transfer and such payments will be deposited in local currency in the relevant country to the credit of the Pieris in a recognized banking institution designated by the Pieris or, if none is designated by Pieris within a period [***] ([***]) days, in a recognized banking institution selected by the AstraZeneca, as the case may be, and identified in a written notice given to the other Party.

9.8.7. Interest Due . AstraZeneca will pay Pieris interest on any undisputed payments that are not paid on or before the date such payments are due under this Agreement at a rate of [***] percent ([***]%) above LIBOR per annum or the maximum applicable legal rate, if less, calculated on the total number of days such payment is delinquent.

In the event of disagreement, and such filing shall as a minimum cover, as applicable, the Collaboration Product (i.e. the Lead Candidate) and the [***] ([***]) Collaboration Product Back-Up Hits selected by AstraZeneca pursuant to Section 4.3.3.4 and any Lead Product Back-Up Hits together with any Anticalin with [***] ([***]) or fewer differences in the variable region of the Anticalin when compared to the foregoing. AstraZeneca shall have final decision-making with respect to such applications except that Pieris Know-How and Pieris Confidential

Page 97 of 163

Information shall not be incorporated into such application without Pieris’ prior written consent. AstraZeneca shall not pursue a Patent claim within the Lead Product IP or Collaboration Product IP that is not limited to the applicable Target. AstraZeneca will consult with Pieris, on its strategy for the Prosecution and Maintenance of all such Patents within the Key IP. AstraZeneca will furnish Pieris, via electronic mail or such other method as mutually agreed by the Parties, copies of substantive proposed filings and documents received from outside counsel in the course of Prosecuting and Maintaining such Patents within the Key IP, or copies of documents filed with the relevant patent offices or other Governmental Authorities with respect to such Patents within the Key IP, and such other substantive documents related to the Prosecution and Maintenance of such Patents within the Key IP, and as applicable in sufficient time prior to filing such document or making any payment due thereunder to allow for review and comment by Pieris and will consider in good faith timely comments from Pieris thereon. AstraZeneca will furnish Pieris, via electronic mail or such other method as mutually agreed by the Parties, copies of documents filed with the relevant national patent offices or other Governmental Authorities with respect to such Patents within the Key IP. Each Party will sign, or will use best efforts to have signed, all legal documents as are reasonably necessary to Prosecute and Maintain Patents within the Key IP. Pieris shall, if requested by AstraZeneca, consent to opt out of the Unitary Patent in respect of any Patent within the Key IP. AstraZeneca shall also notify Pieris in writing (which may be via email) promptly if AstraZeneca files any Patents within the AstraZeneca Background Improvement IP whose initially filed claims Cover a Product at the time of filing.

10.4.4.2. Dropped Key IP . In the event that AstraZeneca elects not to Prosecute and Maintain (or continue to Prosecute and Maintain, including filing a Patent claiming priority to a Patent prior to its issuance), any Patent within the Lead Product IP, Collaboration Product IP, or Grantback IP anywhere in the world, AstraZeneca will notify Pieris at least sixty (60) days before any such Patent would become abandoned, no longer available or otherwise forfeited, and Pieris will have the right (but not the obligation), at Pieris’ sole discretion to Prosecute and Maintain such Patent worldwide in the names of both AstraZeneca and Pieris at Pieris’ sole cost (which right will include the right to file additional Patents claiming priority to such Patent). With respect to any Patents within the Key IP other than Patents within the Lead Product IP, Collaboration Product IP, or Grantback IP, AstraZeneca shall offer Pieris the same notifications and rights set forth in the first sentence of this Section 10.4.4.1 to the extent that (i) such Patent Covers a therapeutic method of use of the applicable Product and that such Patent as filed contains at least one (1) claim specific to the use of Anticalin proteins (lipocalin muteins) in the Respiratory Field, or (ii) such Patent relates solely to one or more Product(s) and not to other AstraZeneca products.

Page 98 of 163

10.4.5. Other Anticalin Patents Against a Target . At any time after the initial filing of a provisional or non-provisional Collaboration Product Patent with respect to a given Product, Pieris may file for Patent protection with respect to any Anticalin protein described in Section 2.4 . Such Patent shall not claim any Anticalin protein against a Designated Target within the Lead Candidate and Back-Up Hits Exclusivity Field. Pieris shall not take any action when Prosecuting and Maintaining any such Patent that would materially prejudice any Lead Product Patent or Collaboration Product Patent. For clarity, Pieris shall own and fully control such Patents, AstraZeneca shall not have a license to such Patents, and such Patents shall not be considered Pieris IP, Arising IP, or Collaboration Product IP. Pieris shall provide written notice, together with the filing number, to AstraZeneca as soon as reasonably possible if it files any such Patent and Pieris shall also inform AstraZeneca in writing [***] ([***]) [***] before any such Patent is granted in the United States.

10.4.6. Patent Miscellaneous .

Page 99 of 163

10.6.1. If the manufacture, use, importation, offer for sale or sale of any Product pursuant to this Agreement results in any claim, suit or proceeding alleging patent infringement or trade secret misappropriation against Pieris or AstraZeneca, then such Party shall promptly notify the other Party hereto. The Parties shall cooperate with each other in connection with any such claim, suit or proceeding and shall keep each other reasonably informed of all material developments in connection with any such claim, suit or proceeding.

10.6.2. If a Third Party asserts that a Patent owned by or licensed to it are infringed by the development, manufacture, use, importation, offer for sale or sale of a Lead Product or Collaboration Product by AstraZeneca or its Affiliates (or by Pieris in the case of Co-Development or Co-Commercialization), or that its trade secrets were misappropriated in connection with such activity, then AstraZeneca shall have the exclusive right and responsibility to resolve any such claim, whether by obtaining a license from such Third Party, by defending against such Third Party’s claims or otherwise, and shall be solely responsible for the defense of any such action, any and all costs incurred in connection with such action (including, without limitation, attorneys’ and expert fees) and all liabilities incurred in connection therewith. Notwithstanding the above, AstraZeneca shall not enter into any settlement of any such claim without the prior written consent of Pieris if such settlement would require Pieris to be subject to an injunction or to make any monetary payment to AstraZeneca or any Third Party, or admit any wrongful conduct by Pieris or its Affiliates, or would limit or restrict the claims of or admit any invalidity and/or unenforceability of any of the Patents Controlled by Pieris, or have any impact on activities outside the Field.

10.6.3. If an action for infringement is commenced against Pieris, its licensees or its sublicensees related to Pieris’ conduct of the research program within the scope of the Lead Product Development Plan or a Collaboration Product Development Plan or the discovery of a Product, then Pieris shall have the right (but not the obligation) to defend such action at its own expense, and AstraZeneca shall assist and cooperate with Pieris, at Pieris’ expense, to the extent necessary in the defense of such suit. Pieris shall have the right to settle the suit or consent to an adverse judgment thereto, in its sole discretion, so long as such settlement or adverse judgment does not adversely affect the rights of AstraZeneca and its Affiliates (including any Patents Controlled by any of them). Pieris shall assume full responsibility for the payment of any award for damages, or any amount due pursuant to any settlement entered into by it with such Third Party.

10.6.4. Notwithstanding Section 10.6.3 , if the infringement action against Pieris is the result of its co-Development or co-Commercialization activities with respect to any Product, then it shall be treated as an action under Section 10.6.2 and AstraZeneca shall have the exclusive right and responsibility to resolve any such claim subject to the provisions of that Section.

Page 100 of 163

10.7. Enforcement .

10.7.1. AstraZeneca shall have the full and unrestricted right, but not the obligation, to bring and control an appropriate suit or other action against any person or entity engaged in any infringement action or proceeding to the extent directly relating to Key IP and any Products in the Field, but excluding the [***] Grant-Back Field with respect to the Lead Product (“ Infringement Action ”), in its own name and entirely under its own direction and control. In the event that AstraZeneca does not wish to enforce such Patents against such a potential infringer, then AstraZeneca shall deliver prompt written notice thereof to Pieris. If AstraZeneca requests so, Pieris shall reasonably cooperate with AstraZeneca in the planning and execution of any such action to enforce such Patents (including the obligation to be named or joined as a party in a lawsuit, as applicable). Notwithstanding the foregoing, if AstraZeneca does not either initiate such an Infringement Action or grant adequate rights and licenses to such Third Party within one hundred twenty (120) days after AstraZeneca’s receipt of a notice of infringement (or sooner if any deadlines require action prior to such one hundred and twenty (120) days) and the infringement relates to the launch or a threat to launch a Biosimilar version of a Product, then Pieris will have the second right, but not the obligation, to initiate such Infringement Action, but solely with respect to any Patent Right within the Pieris IP, Lead Product IP, Collaboration Product IP and Grantback IP. All monies recovered upon the final judgment or settlement of any such suit or action to enforce such Patents subtracting any costs that the Parties bore in connection with such suit or action, shall be treated as Net Sales to the extent such monies recovered are designated as lost profits, and shall otherwise be divided between the Parties with [***] percent ([***]%) paid by the enforcing Party to the non-enforcing Party and [***] percent ([***]%) retained by enforcing Party.

10.7.2. For avoidance of doubt, AstraZeneca shall not have the right to assert or enforce any other Patents owned or Controlled by Pieris under this Agreement, such as the Patent Rights within the Pieris Platform IP or Pieris Platform Improvement IP, against a Third Party under any circumstances and Pieris shall not be under any obligation to enforce such Patent Rights.

10.7.3. Notwithstanding Section 10.7.1 , Pieris shall have the right, but not the obligation, to bring and control an appropriate suit or other action against any person or entity engaged in any infringement action or proceeding under the Pieris IP (including the Lead Product IP) and Arising IP to the extent directly relating to a Lead Product Patent and to the Lead Product in the [***] Grant-Back Field (“ [***] Infringement Action ”), in its own name and entirely under its own

Page 101 of 163

direction and control with the prior written consent of AstraZeneca. If AstraZeneca provides such consent, the Parties shall reasonably cooperate with in the planning and execution of any such action to enforce such Patents (including the obligation to be named or joined as a party in a lawsuit, as applicable). All monies recovered upon the final judgment or settlement of any such suit or action to enforce such Patents subtracting any costs that Pieris or AstraZeneca bore in connection with such suit shall be retained in their entirety by Pieris. Even in the event that Pieris does not wish to bring an action under this Section 10.7.3 , AstraZeneca still shall not have the right to bring or control any [***] Infringement Action. For avoidance of doubt, nothing in this Section shall restrict Pieris from enforcing any other Patent or Intellectual Property Rights against any Third Party in the [***] Grant-Back Field (including any Patents filed by Pieris as described in Section 10.3 ).

10.8. Common Interest Disclosures . With regard to any information or opinions disclosed pursuant to this Agreement by one Party to each other regarding intellectual property and/or technology owned by Third Parties, the Parties agree that they have a common legal interest in determining whether, and to what extent, Third Party intellectual property rights may affect the conduct of the Development Plans and/or Lead Product and/or Collaboration Products, and have a further common legal interest in defending against any actual or prospective Third Party claims based on allegations of misuse or infringement of intellectual property rights relating to the conduct of the Development Plans and/or Lead Product and/or Collaboration Products. Accordingly, the Parties agree that all such information and materials obtained by Pieris and AstraZeneca from each other will be used solely for purposes of the Parties’ common legal interests with respect to the conduct of the Agreement. All information and materials will be treated as protected by the attorney-client privilege, the work product privilege, and any other privilege or immunity that may otherwise be applicable. By sharing any such information and materials, neither Party intends to waive or limit any privilege or immunity that may apply to the shared information and materials. Neither Party shall have the authority to waive any privilege or immunity on behalf of the other Party without such other Party’s prior written consent, nor shall the waiver of privilege or immunity resulting from the conduct of one Party be deemed to apply against any other Party.

10.9. Patent Term Extensions . AstraZeneca shall use commercially reasonable efforts to obtain all available patent term extensions, adjustments or restorations, or supplementary protection certificates (“ SPCs ”, and together with patent term extensions, adjustments and restorations, “ Patent Term Extensions ”) for each Product with respect to the AstraZeneca Background IP and Key IP. Pieris shall execute such authorizations and other documents and take such other actions as may be reasonably requested by AstraZeneca to obtain such Patent Term Extensions. All filings for such Patent Term Extensions shall be made by AstraZeneca; provided, that in the event that AstraZeneca

Page 102 of 163

elects not to file for a Patent Term Extension, AstraZeneca shall (a) promptly inform Pieris of its intention not to file and (b) grant Pieris the right to file for such Patent Term Extension. Each Party shall execute such authorizations and other documents and take such other actions as may be reasonably requested by the other Party to obtain such extensions. Pieris shall not and shall procure that its Affiliates and licensees shall not apply for a Patent Term Extension for PRS-060 in the [***] Grant-Back Field without AstraZeneca’s prior written consent. The Parties shall cooperate with each other in gaining patent term restorations, extensions and/or SPCs wherever applicable to such Patents. For avoidance of doubt, AstraZeneca shall not be permitted to apply for any Patent Term Extensions using the Pieris Platform IP without the prior written consent of Pieris.

If a Party is required by Law to disclose Confidential Information of the other Party that is subject to the non-disclosure provisions of this Section 11.1 , such Party will promptly inform the other Party of the disclosure that is being sought in order to provide the other Party an opportunity to challenge or limit the disclosure.

Page 104 of 163

11.1.4. Notwithstanding Section 11.1.1 , Confidential Information that is permitted or required to be disclosed will remain otherwise subject to the confidentiality and non-use provisions of this Section 11.1 .

11.2. Publication and Publicity .

11.2.1. Publication . Except for disclosures permitted pursuant to Section 11.1 and Section 11.2.2 , if Pieris wishes to make a publication or public presentation relating to the Lead Product or Collaboration Product or if either Party wishes to make a publication or public presentation relating to any jointly carried out activity that contains the Confidential Information of the other Party or any results of Research and Development activities under this Agreement (the “ Publishing Party ”) will deliver to the other Party (the “ Reviewing Party ”) a copy of the proposed written publication or presentation at least [***] ([***]) days prior to submission for publication or presentation. The Reviewing Party will have the right (a) to propose modifications to the publication or presentation for Patent reasons or trade secret reasons or to remove Confidential Information of the Reviewing Party or its Affiliates, and the Publishing Party will remove all Confidential Information of the other Party if requested by the reviewing Party and otherwise reflect such Party’s reasonable comments into consideration, or (b) to request a reasonable delay in publication or presentation in order to protect patentable information. If the Reviewing Party requests a delay, the Publishing Party will delay submission or presentation for a period of [***] ([***]) days (or such shorter period as may be mutually agreed by the Parties) to enable the Reviewing Party to file patent applications protecting such Party’s rights in such information. With respect to any proposed publications or disclosures by investigators or academic or non-profit collaborators, such materials will be subject to review under this Section 11.2.1 to the extent that AstraZeneca or Pieris, as the case may be, has the right and ability (after using commercially reasonable efforts to obtain such right and ability) to do so. Notwithstanding the foregoing, in no event will either Party make a publication regarding a Collaboration Product until the first patent application directed to the composition of matter of such Product has been filed. Further, neither Party will submit or

13.4. Defense, Settlement, Cooperation and Expenses .

Page 111 of 163

indemnification. Upon assuming the defense of a Third Party Claim, the indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the indemnifying Party.

13.4.3. Settlement . With respect to any Third Party Claims relating solely to the payment of money damages in connection with a Third Party Claim and that will not admit liability or violation of Applicable Law on the part of the Indemnified Party or result in the Indemnified Party’s becoming subject to injunctive or other relief or otherwise adversely affecting the business of the Indemnified Party in any manner (such as granting a license or admitting the invalidity of a Patent Controlled by an Indemnified Party), and as to which the indemnifying Party will have acknowledged in writing the obligation to indemnify the Indemnified Party hereunder, the indemnifying Party will have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the indemnifying Party, in its sole discretion, will deem appropriate. With respect to all other Losses in connection with Third Party Claims, where the indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 13.4.1 , the indemnifying Party will have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss provided it obtains the prior written consent of the Indemnified Party (which consent will not be

Page 112 of 163

unreasonably withheld). The indemnifying Party will not be liable for any settlement, consent to entry of judgment, or other disposition of a Loss by an Indemnified Party that is reached without the written consent of the indemnifying Party. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, no Indemnified Party will admit any liability with respect to or settle, compromise or discharge, any Third Party Claim without the prior written consent of the indemnifying Party, such consent not to be unreasonably withheld.

13.4.4. Cooperation . Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party will, and will cause each other Indemnified Party to, cooperate in the defense or prosecution thereof and will furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation will include access during normal business hours afforded to indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making Indemnified Parties and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the indemnifying Party will reimburse the Indemnified Party for all its reasonable Out-of-Pocket Costs and expenses in connection therewith.

13.4.5. Costs and Expenses . Except as provided above in this Section 13.4 , the costs and expenses, including attorneys’ fees and expenses, incurred by the Indemnified Party in connection with any claim will be reimbursed on a Calendar Quarter basis by the indemnifying Party, without prejudice to the indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party.

14.3. Effects of Termination .

14.3.1. E ffects of Termination . In the event of any termination of this Agreement in its entirety or with respect to any given Product or given country other than termination (i) by AstraZeneca for Pieris’ material breach under Section 14.2.1 , (ii) by AstraZeneca due to Pieris’ insolvency under Section 14.2.4 , or (iii) under Section 14.2.2 (termination by mutual agreement), then the following shall apply:

14.3.1.1. At Pieris’ request, AstraZeneca will return to Pieris or destroy (and certify such destruction to Pieris), at Pieris’ option, all Pieris’ Confidential Information related to the terminated Product(s) and Pieris Know-How related to the terminated Product(s) (provided that AstraZeneca shall be entitled to retain one (1) copy for archival and compliance purposes, and as required by Applicable Law or regulatory requirement). At AstraZeneca’s request, subject to Section 14.3.1.6 , Pieris will return to AstraZeneca or destroy (and certify such destruction to AstraZeneca), at AstraZeneca’s option, all other AstraZeneca Confidential Information related to the terminated Product(s) and all other AstraZeneca Know-How related to the terminated Product(s) (provided that Pieris shall be entitled to retain one (1) copy for archival and compliance purposes, and as required by Applicable Law or regulatory requirement).

14.3.1.2. Pieris shall have the right to acquire some or all of the available inventory of the terminated Product, as requested by Pieris, in the possession of AstraZeneca and its Affiliates as of the date of such termination, provided that, if Pieris so acquires any or all such inventory, Pieris shall reimburse AstraZeneca the cost incurred by AstraZeneca for such inventory and if Pieris does not purchase such inventory AstraZeneca shall be entitled to continue selling any such inventory for [***] ([***]) months following the effective date of termination.

14.3.1.3. All licenses and sublicenses granted by Pieris to AstraZeneca hereunder shall terminate, provided however that they will continue solely to enable AstraZeneca to (i) complete sales of Products for any purchase orders that were in place prior to the effective date of termination and (ii) sell off any existing inventory of Products pursuant to Section 14.3.1.2 ; thereafter, AstraZeneca will discontinue Commercialization of the applicable Product.

14.3.1.4. To the extent requested by Pieris, AstraZeneca shall enter into an agreement whereby AstraZeneca assigns its rights to the Lead Product Patents and Collaboration Product Patents (including all Patents therein) to Pieris and grants an exclusive (sub)license to Pieris, under

Page 120 of 163

AstraZeneca Contributed IP and Arising IP reasonably necessary to further Develop, Manufacture and Commercialize the terminated Products (including any Patent Rights or Intellectual Property Rights included in the AstraZeneca Contributed IP or Arising IP related to the device for such terminated Product) on reasonable commercial terms, including adequate indemnities to be agreed upon. For purposes of this Section 14.3.1 , “reasonable commercial terms” means that (i) no upfront or milestone payments shall be due from Pieris to AstraZeneca for such terminated Product, and (ii) any royalties on Net Sales of any terminated Product shall not exceed (a) [***] percent ([***]%) if the effective date of termination for such Product is prior to [***] for such Product, (b) [***] percent ([***]%) if the effective date of termination for such Product is after [***] for such Product but is prior to the [***] for such Product or (c) [***] percent ([***]%) if the effective date of termination for such Product is after the [***] for such Product. Notwithstanding the forgoing, to the extent that the licenses provided under this Section 14.3.1.4 do not include any Intellectual Property rights Covering an inhalation device that is being used for inhaled delivery of the terminated Product, then the royalty rate ceilings set forth under this Section 14.3.1.4 shall be reduced by [***] percent ([***]%). In the event that AstraZeneca has in-licensed Patent Rights from a Third Party specifically pertaining to an inhalation device for use in connection with the terminated Product (“ Device In-License ”), then the royalty rate ceilings set forth under this Section 14.3.1.4 shall also be reduced by [***] percent ([***]%) and Pieris shall pay the royalties associated with such Device In-License to such Third Party. Pieris shall be responsible for paying any royalties, milestones or other sums which may be due to Third Parties in respect of any Intellectual Property Rights licensed by AstraZeneca to Pieris pursuant to this Section 14.3.1.4 . Pieris shall take over responsibility for the Prosecution and Maintenance and shall have sole enforcement rights (with AstraZeneca providing any reasonably requested assistance) of any Patents in the Arising IP and AstraZeneca Background Improvement IP which solely and exclusively Cover the Products.

14.3.1.5. At the request of Pieris, AstraZeneca shall continue all [***] ([***]) [***] and all [***] (including AstraZeneca’s funding or co-funding of such [***]) through Completion of such [***] and completion of such [***].

14.3.1.6. AstraZeneca will, as promptly as practicable, and subject to Pieris’ reasonable assistance and to agreeing reasonable commercial terms pursuant to Section 14.3.1.4 , to the extent legally permissible (including to the extent permitted under AstraZeneca’s obligations to

Page 121 of 163

Third Parties on the effective date of termination), (i) transfer and assign to Pieris or Pieris’ designee AstraZeneca’s right, title and interest in and to all material governmental or regulatory filings and approvals (including all Marketing Approvals and pricing approvals, and Regulatory Materials, in all cases, specifically and exclusively relating to the Development, Manufacture or Commercialization of the terminated Products, and (ii) transfer to Pieris or Pieris’ designee copies of all material Data, Know-How, Clinical Study data and safety data in AstraZeneca’s possession and Control to the extent specifically related to and required for the research, Development, Manufacture or Commercialization of the terminated Products. In addition, AstraZeneca will appoint Pieris as AstraZeneca’s and/or AstraZeneca’s Affiliates’ agent for all terminated Product-related matters involving Regulatory Authorities until all Marketing Approvals, regulatory approvals and other regulatory filings hereunder have been assigned to Pieris or its designee. In the event of (x) failure to obtain assignment or (y) with respect to regulatory items that would otherwise fall within (i) and (ii) but for such materials not being specifically related to the terminated Products, but nonetheless which are reasonably necessary for the Development, Manufacture or Commercialization of the terminated Products above, in each of (x) and (y) AstraZeneca hereby consents and grants to Pieris the right to access and reference (without any further action required on the part of AstraZeneca, whose authorization to file this consent with any Regulatory Authority is hereby granted) any such item with respect to all terminated Products.

14.3.1.7. If AstraZeneca or its Affiliates are Manufacturing Finished Product with respect to terminated Products on the effective date of termination, at Pieris’ option (which must be exercised in writing to AstraZeneca within [***] ([***]) days of the effective date of termination), AstraZeneca or its Affiliates will use commercially reasonable efforts to supply such Finished Product (including any device if applicable, but solely in the form as such terminated Product was being manufactured by AstraZeneca as of the effective date of termination) to Pieris at AstraZeneca’s Fully Burdened Manufacturing Cost plus [***] percent ([***]%), until the earlier of (i) such time as Pieris has procured or developed its own source of such Finished Product supply, or (ii) t[***] ([***]) months following the effective date of termination. Should Pieris not be able to procure or develop its own source of Finished Product supply within [***] ([***]) months, then the Parties will discuss in good faith a potential extension of supply by AstraZeneca to avoid any supply interruption. The Parties will promptly negotiate a supply and related quality agreement to govern the specific terms and conditions of such supply.

Page 122 of 163

14.3.1.8. If Pieris so requests within [***] ([***]) days of the effective date of termination, the Parties will cooperate, to the extent legally permissible (including to the extent permitted under AstraZeneca’s obligations to Third Parties on the effective date of termination), to assign to Pieris any Third Party agreements that are specific to and exclusively relating to the Development, Manufacture or Commercialization of the terminated products to which AstraZeneca is a party, subject to any required consents of such Third Party.

14.3.1.9. Subject to agreeing to reasonable commercial terms pursuant to Section 14.3.1.4 , the Parties will cooperate, to the extent legally permissible (including to the extent permitted under AstraZeneca’s obligations to Third Parties on the effective date of termination), to promptly transfer and assign or exclusively license (or, if applicable, will cause its Affiliates to assign) to Pieris all of AstraZeneca’s (and such Affiliates’) worldwide right, title and interest in and to any registered trademarks or registered internet domain names that are specific to and exclusively used for the terminated Products (it being understood that the foregoing will not include any trademarks or internet domain names that contain the corporate or business name(s) of AstraZeneca or any of its Affiliates or any other products of AstraZeneca or any of its Affiliates).

14.3.1.10. Subject to AstraZeneca’s agreement that it will not incorporate any Intellectual Property Rights, Data or Know-How Controlled by [***] that would be reasonably necessary for Pieris to continue the Development, Manufacture or Commercialization of any terminated Product, AstraZeneca shall not be required to grant a license under or otherwise transfer to Pieris under this Section 14.3.1 any Intellectual Property Rights, Data or Know-How Controlled by [***]. For clarity, AstraZeneca agrees not use any [***] for the Manufacture of any Product. AstraZeneca and its Affiliates (including MedImmune) hereby covenant not to sue (and not to assist Third Parties in suing) Pieris or its Affiliates or Sublicensees alleging infringement or misappropriation of any Intellectual Property Rights (including any claim for Patent infringement) with respect to any terminated Product as it is constituted at the date of termination for any Intellectual Property Rights including Patent Rights Controlled by AstraZeneca and its Affiliates (including MedImmune) at the date of termination or any Patents Controlled by AstraZeneca or its Affiliates after the date of termination to the extent such Patents incorporate Arising IP or AstraZeneca Contributed IP.

Page 123 of 163

14.3.1.11. More generally, the Parties shall cooperate to ensure a smooth and orderly transition of the Product, including any Development, Manufacturing, or Commercialization activities ongoing at the time of termination to Pieris, pursuant to a termination agreement to be negotiated by the Parties within [***] ([***]) months following the termination notice. Such agreement shall be consistent with this Section 14.3.1 .

14.3.1.12. For clarity where a Product is sold as part of a Combination Product, Pieris shall only have rights under this Section 14.3.1 with regard to the Product and Pieris shall not be granted any rights with regard to the other active ingredient.

14.3.2. Termination Due to Competing Product.

14.3.2.1. In the event that this Agreement is terminated (i) by Pieris for AstraZeneca’s material breach of the Non-Compete under Section 8.2.3 or (ii) by AstraZeneca for convenience (but not for Clinical Failure) under Section 14.2.3 where within [***] ([***]) [***] of the effective date of such termination, AstraZeneca Develops, Manufactures or Commercializes a Competing Product (excluding any Competing Product of any Acquiror of AstraZeneca) corresponding to the terminated Product (a) beyond [***], (b) beyond [***] in the event that the terminated product had achieved [***] Prior to the effective date of termination or (c) is no longer at [***] (as defined in Section 8.2.3.7 ) as compared to the [***] of the terminated Product on the effective date of termination, then the following shall apply in addition to the provisions of Section 14.3.1 : AstraZeneca will pay the [***] with respect to such Product within [***] ([***]) days of (1) the effective date of the termination of the Agreement by Pieris with respect to the applicable Product as described in this Section 14.3.2.1(i) above , or (2) AstraZeneca’s initiation of [***] within [***] ([***]) [***] of termination of the corresponding Product by AstraZeneca for convenience as described in this Section 14.3.2.1(ii)(a)-(c) above. In the event that a terminated Product is terminated following [***] but before [***], the [***] shall be the [***] in the [***] for that terminated Product. By way of example, if the Lead Product is terminated under this Section 14.3.2.1 during a [***] and Pieris has not exercised the [***] (i.e., has exercised the [***] Split Option, [***] Cap Option, or has not exercised its CoDev Option), then AstraZeneca shall pay Pieris [***] Dollars ($[***]). In the event that a terminated Product is terminated following [***] but before [***] of such terminated Product, the [***] shall be the [***] in the [***] for that terminated Product. By way of example, if the Lead Product is terminated under this Section 14.3.2.1 after [***] and Pieris has not exercised the [***] (i.e., has exercised the [***] Split Option, [***] Cap Option, or has not exercised its CoDev Option) then AstraZeneca shall pay Pieris [***] Dollars ($[***]). Once any such [***] has been paid no further sums will be due under this Section.

Page 124 of 163

14.3.2.2. For the avoidance of doubt, Section 14.3.2.1 shall not apply if AstraZeneca terminated a Product due to Clinical Failure.

14.3.3. For Material Breach or Insolvency . In the event that AstraZeneca terminates this Agreement as a result of Pieris’ material breach under Section 14.2.1, due to Pieris’ insolvency under Section 14.2.4 , or as a result of Pieris’s Patent challenge under Section 14.2.5.2 , then the following terms shall apply:

14.3.3.1. At the Disclosing Party’s request, the Receiving Party will return to the Disclosing Party or destroy (and certify such destruction to the Disclosing Party), at Disclosing Party’s option, all Disclosing Party’s Confidential Information related to the terminated Product(s) (provided that the Receiving Party shall be entitled to retain one (1) copy for archival and compliance purposes, and as required by Applicable Law or regulatory requirement).

14.3.3.2. All Development, Manufacture and Commercialization of such terminated Product by the Parties shall immediately cease;

14.3.3.3. The licenses granted by each Party to the other with respect to the terminated Product shall immediately terminate; and

14.3.3.4. The non-compete set forth in Section 8.2 regarding the terminated Product will no longer apply;

14.3.4. Rights in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement are, and shall otherwise be deemed to be, for all purposes of Section 365(n) of the United States Bankruptcy Code and of any similar or analogous provisions of Applicable Laws outside of the United States (the “ Bankruptcy Code ”), licenses and rights to “intellectual property” as defined under Section 101(35A) of the U.S. Bankruptcy Code. Each Party agrees that the other Party, as licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code. In the event of the commencement of a bankruptcy proceeding by or against a Party under the Bankruptcy Code (the “ Insolvent Party ”), the other Party shall be entitled to a complete duplicate of (or complete access to, as appropriate) any intellectual property and Know-How licensed to such Party under this Agreement and held by such first Party and its successors and assigns (and all embodiments of such intellectual property and Know-How), provided that, a Party shall not be required to provide any duplicate copies and embodiments of such intellectual

Page 125 of 163

property or Know-How to the other Party so long it has already provided such intellectual property and Know-How it is required to provide to under this Agreement, and, if not already in its possession, shall be promptly delivered to it (a) upon any such commencement of a bankruptcy proceeding upon its written request therefore, unless the Insolvent Party continues to perform all of its obligations under this Agreement, or (b) if not delivered or granted under (a) above, following the rejection of this Agreement by or on behalf of the Insolvent Party upon written request therefore by the other Party.

14.3.5. Survival . The termination or expiration of this Agreement shall not affect any payment of any debts or obligations accruing prior to or after such date of termination or expiration. The provisions of Section 1 (to the extent necessary to give effect to the surviving provisions), Section 2.3 (Grantback License), Sections 2.6.1, 2.6.2, and 2.6.4.2(b) ([***] Grant-Back licenses becoming irrevocable), Section 9.6 (with respect to any Net Sales accrued following the Term during a permitted sell-off period under Section 14.3.1.2 ), Section 9.8.2 (for any final reports and final payments), Section 9.8.3 (Records and Audits), Section 11.1 (Confidentiality except for the last Sentence of Section 11.1.2 ), Section 13 (Indemnification, Liability and Insurance), Section 14 (until completion of termination obligations) and Section 15 (Miscellaneous) will survive the expiration or any termination of this Agreement for any reason, in accordance with their respective terms and conditions, and for the respective duration stated therein, and where no duration is stated, will survive indefinitely. In addition, any Section that is referred to in the above listed Sections shall survive solely for the interpretation or enforcement of the latters.

Such Senior Representatives, or their respective designees, will meet in person or by teleconference as soon as reasonably possible thereafter, and use their good faith efforts to mutually agree upon the resolution of the dispute, controversy or claim.

Page 126 of 163

15.1.2. Limited Escalation for Lead Product and CoDev Products Not Yet in Co-Development . Notwithstanding Section 15.1.1 , to the extent that the Parties fail to reach agreement regarding a matter within the JSC’s decision-making authority and such matter relates to a Product for which Pieris has an unexpired but not yet exercised CoDev Option (including the time period where such Option is not yet exercisable), then such matter shall be resolved by the JSC and if not resolved by the JSC shall be subject to AstraZeneca’s final say and shall not be escalated to Senior Representative as set forth in Section 15.1.1 .

15.1.3. Request for Arbitration . If after negotiating in good faith, the Parties fail after good faith discussions undertaken within reasonable promptness, to reach an amicable agreement within ninety (90) days, then either Party may upon written notice to the other submit to binding arbitration pursuant to Section 15.1.4 below; provided that any dispute within the JSC’s decision-making authority shall be resolved in accordance with Section 3.2.5 , rather than arbitration. No statements made by either Party during such discussions will be used by the other Party or admissible in arbitration or any other subsequent proceeding for resolving the dispute.

15.1.4. Arbitration .

15.1.4.1. Subject to Section 15.2 , any dispute, claim or controversy arising from or related in any way to this Agreement or the interpretation, application, breach, termination or validity thereof, including any claim of inducement of this Agreement by fraud or otherwise, not resolved under the provisions of Section 15.1.1 , will be resolved by final and binding arbitration conducted in accordance with the terms of this Section 15.1.4.1 . The arbitration will be held in [***] according to Rules of Arbitration of the ICC. The arbitration will be conducted by a panel of three (3) arbitrators with significant experience in the pharmaceutical industry, unless otherwise agreed by the Parties, appointed in accordance with applicable ICC rules. Any arbitration herewith will be conducted in the English language to the maximum extent possible. The arbitrators will render a written decision no later than [***] following the selection of the arbitrators, including a basis for any damages awarded and a statement of how the damages were calculated. Any award will be promptly paid in U.S. dollars free of any tax, deduction or offset. Each Party agrees to abide by the award rendered in any arbitration conducted pursuant to this Section 15.1.4 . With respect to money damages, nothing contained herein will be construed to permit the arbitrator or any court or any other forum to award punitive or exemplary damages, except in the case of breach of Section 11.1 . By entering into this agreement to arbitrate, the Parties expressly waive any claim for punitive or exemplary damages, except in the case of breach of Section 11.1 . Each Party will pay its legal fees and costs related to the arbitration (including witness and expert fees). Judgment on the award so rendered will be final and may be entered in any court having jurisdiction thereof.

Page 127 of 163

15.1.4.2. EACH PARTY HERETO WAIVES ITS RIGHT TO TRIAL OF ANY ISSUE BY JURY. EACH PARTY HERETO WAIVES ANY CLAIM FOR ATTORNEYS’ FEES AND COSTS AND PREJUDGMENT INTEREST FROM THE OTHER.

15.1.5. Court Actions . Nothing contained in this Agreement will deny either Party the right to seek injunctive or other equitable relief from a court of competent jurisdiction in the context of a bona fide emergency or prospective irreparable harm, and such an action may be filed and maintained notwithstanding any ongoing dispute resolution discussions or arbitration proceeding. In addition, either Party may bring an action in any court of competent jurisdiction to resolve disputes pertaining to the validity, construction, scope, enforceability, infringement or other violations of patents or other proprietary or Intellectual Property Rights, and no such claim will be subject to arbitration pursuant to Section 15.1.4 .

15.2. Governing Law, Jurisdiction, Equitable Relief, Losses, and Remedies .

15.2.1. This Agreement will be governed by and construed and enforced in accordance with the laws of the [***], without reference to any rules of conflicts of laws. For clarification, any dispute relating to the scope, validity, enforceability or infringement of any Patents will be governed by and construed and enforced in accordance with the patent laws of the applicable jurisdiction.

15.2.2. Each Party acknowledges and agrees that the restrictions set forth in Section 8.2 of this Agreement are reasonable and necessary to protect the legitimate interests of the other Party and that the other Party would not have entered into this Agreement in the absence of such restrictions, and that any breach or threatened breach of any of these provisions will probably result in irreparable injury to the other Party for which there will be no adequate remedy at law. In the event of a breach or threatened breach of any such provision, each Party will be authorized and entitled to obtain from any court of competent jurisdiction equitable relief, whether preliminary or permanent, specific performance and an equitable accounting of all earnings, profits and other benefits arising from such breach, which rights will be cumulative and in addition to any other rights or remedies to which such Party may be entitled in law or equity. Each Party agrees to waive any requirement that the other Party (a) post a bond or other security as a condition for obtaining any such relief, and (b) show irreparable harm, balancing of harms, consideration of the public interest or inadequacy of monetary damages as a remedy. Nothing in this Section 15.2.2 is intended, or should be construed, to limit a Party’s rights to equitable relief or any

Page 128 of 163

other remedy for a breach of any other provision of this Agreement. Except for (i) any amount awarded to be paid by one Party to the other by the panel of arbitrators in a final and binding arbitration proceeding adjudicated under Section 15.1.4.1 , and (ii) any offset of undisputed but unpaid amounts under this Agreement, neither Party will have the right to set off any amount it is owed or believes it is owed against payments due or payable to the other Party under this Agreement.

15.2.3. Neither Party will be entitled to recover any Losses relating to any matter arising under one provision of this Agreement to the extent that such Party has already recovered Losses with respect to such matter pursuant to other provisions of this Agreement (including recoveries under Section 13 ) or the Platform Agreement.

15.3. Antitrust Filing .

15.3.1. Each Party agrees to prepare and make or cause to be prepared and made appropriate filings under the HSR Act and any other antitrust requirements relating to this Agreement and the transactions contemplated under this Agreement within [***] ([***]) Business Days after the Execution Date. Each of the Parties agrees to cooperate in the antitrust clearance process, including by furnishing to the other Party such necessary information and reasonable assistance as the other Party may request in connection with its preparation of any filing or submission that is necessary under the HSR Act and other antitrust requirements, and to furnish promptly with the United States Federal Trade Commission (“ FTC ”), the Antitrust Division of the United States Department of Justice (“ DOJ ”) and any other antitrust authority, any information reasonably requested by them in connection with such filings. Each Party shall furnish copies (subject to reasonable redactions for privilege or confidentiality concerns) of, and shall otherwise keep the other Party apprised of the status of any communications with, and any inquiries or requests for additional information from, the FTC, DOJ and any other antitrust authority, and shall comply promptly with any such inquiry or request. Each Party shall give the other Party the opportunity to review in advance, and shall consider in good faith the other Party’s reasonable comments in connection with any proposed filing or communication with the FTC, DOJ or any other antitrust authority. Each Party shall consult with the other Party, to the extent practicable, in advance of participating in any substantive meeting or discussion with the FTC, the DOJ or any other antitrust authority with respect to any filings, investigation or inquiry and, to the extent permitted by such antitrust authority, give the other Party to the opportunity to attend and participate in such meeting or discussion. Neither Party shall withdraw its filing under the HSR Act or agree to delay the Effective Date without the prior written consent of the other Party. The Parties’ rights and obligations hereunder apply only in so far as they relate to the Agreement and to the transactions contemplated under the Agreement.

Page 129 of 163

15.3.2. Each Party shall use commercially reasonable efforts to obtain the expiration or early termination of the HSR Act and any other clearance required under other antitrust requirements relating to the Agreement and the transactions contemplated under the Agreement. Commercially reasonable efforts as used in this Section 15.3.2 will not include proposing, negotiating, committing to and effecting, by consent decree, hold separate order, or otherwise, (a) the sale, divestiture, disposition, licensing or sublicensing of any of a Party’s or its Affiliates’ assets, properties or businesses, (b) behavioral limitations, conduct restrictions or commitments with respect to such assets, properties or business, or of any of the rights or obligations of a Party under this Agreement, or (c) defending through litigation any claim asserted in court by any party that would restrain, prevent or delay the Effective Date.

15.3.3. Other than the provisions of Section 14.1 , Section 11 , and Section 15 which shall apply as of the Execution Date, the rights and obligations of the Parties under this Agreement will not become effective until the waiting period under the HSR Act has been terminated or expired, or any other timeline required by another antitrust authority and there is no proceeding, order, injunction or judgment relating thereto, pending before any governmental authority in which it is sought to restrain or prohibit the transaction(s) contemplated hereby. Upon the occurrence of the Effective Date, all other provisions of this Agreement shall become effective automatically without the need for further action by the Parties.

15.3.4. AstraZeneca shall be responsible for the filing fee related to any initial filing required by the HSR Act. Thereafter, each Party shall be responsible for its fees and costs associated with the preparation and submission of any required notification and report form under the HSR Act (or to any other antitrust authority), and the provision of any supplemental information to the FTC, DOJ or other antitrust authority, including any legal fees incurred by such Party in connection with such Party’s obligations pursuant to this Section 15.3 .

Page 130 of 163

15.4. Assignments and Successors . Neither this Agreement nor any obligation of a Party hereunder may be assigned by either Party without the consent of the other, except that each Party may assign this Agreement and the rights, obligations and interests of such Party, in whole or in part, without the other Party’s consent, to any of its Affiliates for as long as such entity remains an Affiliate, to any purchaser of all or substantially all of its assets to which this Agreement or relevant part relates or to any successor corporation resulting from any merger, consolidation, share exchange or other similar transaction. In addition, Pieris may assign or transfer its rights to receive payments under this Agreement (but no liabilities), without AstraZeneca’s consent, to an Affiliate or to a Third Party in connection with a payment factoring transaction; provided, however, that Pieris will provide AstraZeneca advance notice of any such proposed payment factoring transaction giving AstraZeneca a reasonable opportunity to provides comments (which Pieris will consider in good faith). Upon Pieris’ request, AstraZeneca shall provide royalty reports described under Section 9.8 and direct payments described under Section 8.2.4.3 to such Third Party and such provision and direction shall satisfy any obligation to provide such a payment or report to Pieris. Any purported assignment or transfer made in contravention of this Section 15.3 will be null and void.

15.5. Acquiror IP . Notwithstanding anything to the contrary in this Agreement, in the event of a Change of Control involving either Party or its business after the Execution Date (the Third Party acquiring such Party or its business being the Acquiror), whether by merger, asset purchase or otherwise, as to any such Acquiror, the non-acquired Party shall not obtain rights, licenses, options or access to any Intellectual Property Rights or Know-How, product candidates or products that are held by the Acquiror or any Affiliate of the Acquiror that becomes an Affiliate of the acquired Party as a result of such acquisition (but excluding the acquired Party itself), that were not generated through any use or access to the Intellectual Property Rights or Know-How of the acquired Party, or that are not used by the acquired Party in connection with a Product under this Agreement.

15.6. Change of Control Involving Pieris .

15.6.1. Notice . Pieris will provide written notice (“ COC Notice ”) to AstraZeneca within [***] ([***]) [***] following the closing of a Change of Control involving Pieris, and such notice will identify the Third Party acquiring company (the “ COC Acquiror ”).

15.6.2. Effect on Pieris Co-Development and Co-Commercialization Options . In the event of a Change of Control with respect to Pieris there shall be no impact on Pieris’ Co-Development and Co-Commercialization options as set forth in this Agreement; provided that, if such Change of Control is with an entity that, in the Calendar Year prior to such Change of Control, had revenues during its most recently concluded fiscal year from the sale of biopharmaceutical products that are within the top [***] ([***]) highest in the world (a “ Top [***]

Page 131 of 163

Pharma Company ”), then (i) AstraZeneca shall be permitted, by written notice to Pieris, to immediately terminate any unexercised CoDev Option and Co-Commercialization Options and, effective upon [***] ([***]) months prior written notice, to terminate Pieris’ rights under any Co-Commercialization Options that were exercised by Pieris prior to the closing of such Change of Control and (ii) if Pieris has exercised a CoDev Option, from and after the closing of such Change of Control, the resultant CoDev Products shall be treated as if they were Products for which Pieris does not have or has not exercised a CoDev Option with respect to the information sharing only (i.e., such Product shall not be subject to decision-making through the joint committee structure and AstraZeneca shall be entitled to disband the JSC and JDC). A Top [***] Pharma Company COC Acquiror Co-Developing a Product under this Agreement would specifically be entitled to the information reporting and sharing set forth in Sections 4.8 and 5.4.2 (except that AstraZeneca shall not be required to provide: (a) information that is specific to the Product and does not have any impact on Anticalin proteins per se; or (b) copies of such correspondence required by that Section 5.4.2 or to allow Pieris or Pieris’ successor to review and comment on any proposed response to such correspondence), but not as set forth in Sections 5.4.1, 5.5 and 6.4 . For clarity, the payment and other obligations of AstraZeneca with respect to such Co-Developed Product would not be altered. For avoidance of doubt, if the COC Acquiror is not a Top [***] Pharma Company, then there shall be no change to the rights granted to Pieris under this Agreement.

15.7. Force Majeure . No Party will be held responsible to the other Party nor be deemed to be in default under, or in breach of any provision of, this Agreement for failure or delay in performing any obligation of this Agreement when such failure or delay is due to force majeure, and without the fault or negligence of the Party so failing or delaying. For purposes of this Agreement, force majeure means a cause beyond the reasonable control of a Party, which may include acts of God; acts, regulations, or laws of any government; war; terrorism; civil commotion; fire, flood, earthquake, tornado, tsunami, explosion or storm; pandemic; epidemic and failure of public utilities or common carriers. In such event the Party so failing or delaying will immediately notify the other Party of such inability and of the period for which such inability is expected to continue. The Party giving such notice will be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so long as it is so disabled for up to a maximum of [***] ([***]) [***], after which time the Parties will negotiate in good faith any modifications of the terms of this Agreement that may be necessary to arrive at an equitable solution, unless the Party giving such notice has set out a reasonable timeframe and plan to resolve the effects of such force majeure and executes such plan within such timeframe. To the extent possible, each Party will use reasonable efforts to minimize the duration of any force majeure.

Exhibit 1.110: Fully Burdened Manufacturing Cost

A.	General Principles

The costs of Finished Product supplied by a Party for Development supply requirements or commercial supply requirements shall be at Fully Burdened Manufacturing Cost, calculated as described in Section B of this Exhibit, plus, if applicable, the Cost of Finishing, as described in Section C of this Exhibit below.

Fully Burdened Manufacturing Cost accumulates costs as they are incurred and may or may not utilize a standard cost system; provided that t o the extent a standard cost system for the Product is used for internal purposes at a Party, Fully Burdened Manufacturing Costs shall accumulate utilizing such standard cost system.

Fully Burdened Manufacturing Cost shall be calculated using methodology that is in accordance with a Party’s Accounting Standards at the election of such Party and consistently applied by such Party throughout its operations, without any mark-up. A Party may utilize a standard Fully Burdened Manufacturing Cost when reporting its commercial supply cost or Development supply cost, but will true-up such standard to its actual Fully Burdened Manufacturing Cost using a methodology that is in accordance with such Party’s Accounting Standards consistently applied by such Party.

If the Product is Manufactured in a Party’s facility that is also used to manufacture other products not included within the scope of this Agreement (a “ Shared Facility ”), only the value of the specific resources used for or reasonably allocated to the Manufacture of Product shall be included in the calculation of Fully Burdened Manufacturing Costs. The cost of idle or underutilized capacity (but not designated reserved capacity in a Product Development Plan or a Commercialization Plan) in a Shared Facility shall not be included in the calculation of Fully Burdened Manufacturing Cost.

Any reasonable capital expenditures incurred by a Party in the ordinary course of capacity planning in providing capacity for the Manufacture of Finished Product (including Formulated Bulk Product contained therein) shall be the responsibility of such Party. Depreciation related to other capital expenditures, calculated using methodology that is in accordance with Accounting Standards and consistently applied by a Party throughout its operations, shall be included in Fully Burdened Manufacturing Costs, as applicable. To the extent material modifications to a Party’s or its Affiliates’ facilities, or construction of new facilities by a Party or any of its Affiliates, are needed to provide capacity for the Manufacture of Finished Product, the Parties will agree to the allocation of any capital expenditures with respect thereto between the Parties.

B.	Fully Burdened Manufacturing Cost

1.	“ Fully Burdened Manufacturing Cost ” includes the following costs of preparations for, and the Manufacture of, Finished Product (including Formulated Bulk Product contained therein) (which for the purposes of this Section B shall include unformulated, formulated and failed lots).

Page 144 of 163

Direct Costs incurred by a Party:

Direct labor, based on the actual hours consumed by manufacturing and facility personnel for Finished Product charged at an average hourly wage rate that is designed to approximate actual cost for each employee’s position.

Direct labor fringe benefits, including, compensation expense (other than wages included in direct labor cost in paragraph B.1(i)1), payroll taxes and benefits allocated based on a proportionate percentage of direct labor costs charged to the Finished Product to total actual plant-wide labor costs, plus Product specific travel.

Materials and supplies for making Finished Product (including Formulated Bulk Product contained therein), based on actual costs including any applicable freight, taxes, duties, customs or import fees, less any discounts or free goods.

Other costs directly associated with or actually consumed for Finished Product (including Formulated Bulk Product contained therein), including, facility costs, depreciation, waste removal, miscellaneous supplies, outside testing, consulting fees, occupancy costs, maintenance, rent, insurance and site service support.

ii.

Indirect Costs incurred by a Party:

Plant support services, which includes functions such as quality control, process sciences, quality assurance, regulatory and validation. All general costs for each plant support service department, which includes, labor, payroll taxes, fringe benefits, materials and supplies, outside testing, consulting fees, depreciation, maintenance and occupancy costs, shall be allocated to the cost of the Product based on the proportion of actual labor hours consumed by each plant support service department on the Finished Product to total actual labor hours consumed by each plant support service department on all of a Party’s products or its Affiliates’ or collaborators’ products.

Overhead costs required to support the Manufacture of the Finished Product (including the Formulated Bulk Product contained therein). These overhead costs are allocated either based on actual labor hours or manufacturing process area square footage, but are only costs directly related to the plant in which the Product is Manufactured. Overhead costs allocated based on actual labor hours consumed include, general materials and supplies, consulting costs, and other labor costs such as general plant maintenance, management, engineering, janitorial services and administration, information services, travel and training, and vacation, holiday, personal and sick time. Overhead costs allocated based on Manufacturing process area square footage consist primarily of general facility costs that include, facility services and supplies, utilities, rent, real estate taxes, depreciation, general and preventative maintenance, insurance and waste removal.

Page 145 of 163

iii.

The cost of a Third Party contract manufacturer as invoiced to a Party without any mark-up, including any fees paid to such Third Party to reserve capacity for the Product; provided that the Parties will share any capital expenditures paid to a Third Party contract manufacturer as Development Costs.

Notwithstanding the foregoing, (i) Fully Burdened Manufacturing Cost shall include costs incurred with respect to, or as a result of, spoilage, obsolescence, expiration, or loss or failed or destroyed batches of Product except to the extent attributable to a Party’s or any of its Affiliates’ gross negligence or willful misconduct and (ii) any reimbursement from a Party to the other Party for capital expenditures in such other Party’s plant under this Agreement shall not be included in the basis of assets used to calculate depreciation included in Fully Burdened Manufacturing Costs.

Cost of Finishing . Cost of finishing is the cost of filling, device Manufacture and assembly, packaging, labeling and testing Finished Product, including freight, insurance and quality control. If such filling, device Manufacture and assembly, packaging, labeling or testing is performed by or on behalf of a Party, it shall be billed by the Party at its actual cost without any profit for the Party or mark-up by the Party. If such filling, device Manufacture and assembly, packaging, labeling, or testing is performed by a Third Party, the finishing, filling, device Manufacture and assembly, packaging and testing costs will be billed by the Party that contracts with the Third Party responsible for such activities at its Out-of-Pocket Costs without any mark-up and will include any fees paid to such Third Party to reserve capacity for the Product to the extent not included in the Fully Burdened Manufacturing Cost.

PRESS RELEASE

Pieris Pharmaceuticals and AstraZeneca Collaborate to Develop and Commercialize Anticalin-Based Inhaled Treatments for Respiratory Diseases

•

Pieris to receive $57.5 million USD in upfront and near-term milestone payments

•

Pieris has the potential to receive development-dependent milestones and eventual commercial payments for all products not exceeding $2.1 billion as well as tiered royalties

•

For programs co-developed by Pieris, the Company will be entitled to receive increased royalties or a gross margin share on worldwide sales, dependent on the level of investment to which Pieris commits

•

Pieris will host a conference call on Wednesday, May 3 ^rd at 10am EDT to discuss the collaboration

Boston, MA, May 3, 2017 – Pieris today announced a strategic collaboration in respiratory diseases with AstraZeneca to develop novel inhaled drugs that leverage Pieris’ Anticalin ^® platform, including its lead preclinical drug candidate, PRS-060.

Anticalin molecules are engineered proteins which can mimic antibodies by binding to sites either on other proteins or on small molecules. They are smaller than monoclonal antibodies, offering the potential of direct delivery to the lung.

Under the collaboration, Pieris will be responsible for advancing its preclinical lead candidate, PRS-060, into Phase 1 clinical trials in 2017. PRS-060 is an Anticalin against interleukin-4 receptor alpha (IL-4Rα) with potential in asthma. AstraZeneca will fund all clinical development and subsequent commercialization programs and Pieris has the option of co-development and co-commercialization in the US from Phase 2a onwards. In addition, the parties will collaborate to progress four additional novel Anticalins against undisclosed targets for respiratory diseases with Pieris having the option to co-develop and co-commercialize in the US two of these programs.

Mene Pangalos, Executive Vice President, Innovative Medicines and Early Development Biotech Unit and Business Development, said: “At AstraZeneca, discovering and developing innovative new medicines to treat respiratory diseases is a key strategic priority. Our alliance with Pieris adds an important new modality to our respiratory portfolio and builds on our scientific expertise in inhaled formulation technologies. Pieris shares our passion for ground-breaking science and we look forward to working together to develop new, life-changing treatment options for patients.”

Page 157 of 163

Stephen Yoder, President and Chief Executive Officer of Pieris, said: “Our partnership with AstraZeneca accelerates the transformation of Pieris into a fully-integrated drug development and commercial organization, comprising two main pillars in immunology: respiratory diseases and immuno-oncology, each of which is now anchored by a major alliance. We recognize AstraZeneca’s unparalleled expertise in the development of inhaled drugs, which will maximize the potential of PRS-060 and other inhaled Anticalin molecules to become valuable assets for both companies.”

AstraZeneca will make an upfront and near term milestone payments to Pieris in the amount of $57.5 million—$45 million USD of upfront payments and $12.5 million USD for the initiation of the PRS-060 Phase 1 trial. Pieris has the potential to receive development-dependent milestones and eventual commercial payments for all products not exceeding $2.1 billion as well as tiered royalties on the sales of any potential products commercialized by AstraZeneca. For programs co-developed by Pieris, the Company stands to receive increased royalties or a gross margin share on worldwide sales equal, dependent on the level of investment to which Pieris commits.

Louis Matis, M.D., Senior Vice President and Chief Development Officer of Pieris, said: “AstraZeneca, a leading innovator in respiratory diseases with considerable expertise in the development of inhaled products, is the ideal partner to exploit the potential of our platform in respiratory diseases. Based on the limitations of many types of biologic molecules, direct delivery to the lungs via inhalation has been challenging to date for other classes of therapeutic proteins. Anticalin proteins have unique properties, not least of which is their size and stability, and show considerable promise for this route of delivery.”

The collaboration agreement is conditional upon the expiration or early termination of the applicable waiting period (and any extension thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

PRS-060, an Anticalin protein potently engaging IL-4Rα, is being developed for patients suffering from moderate to severe asthma, many of whom are not able to control their asthma well with currently available medications. In a large proportion of asthma patients, the Th2 pathway plays an important role. IL-4 and IL-13 are the main cytokines involved in Th2-mediated asthma. Both signal via IL-4Rα, making IL-4Rα a cornerstone intervention point. PRS-060 differentiates from antibody approaches through inhaled delivery directly into the lungs, potentially resulting in efficacy and safety benefits. The local delivery may allow for lower doses than systemically administered antibodies, potentially also resulting in a significant cost of goods advantage over those therapies. Pieris has demonstrated proof of concept in animals as well as feasibility for pulmonary delivery with PRS-060.

Conference Call

Pieris will host an investor conference call on Wednesday, May 3, 2017 at 10:00 AM (EDT) to discuss the collaboration. To access the call, participants may dial 1-877-407-8920 (US & Canada) or 1-412-902-1010 (International) at least 10 minutes prior to the start of the call.

WHEREAS , Pieris and Servier have entered into the Agreement, under which the Parties are Researching and Developing the Products;

WHEREAS , the Parties wish to amend certain provisions of the Agreement related to payment obligations of the Parties in connection with terminated Products or Dropped Products;

1.	LICENSED BUILDING BLOCK PAYMENT OBLIGATIONS IN THE CASE OF DROPPED OR TERMINATED PRODUCTS

1.1 Section 4.1.3 of the Agreement contemplates that each Party is responsible for contributing certain Building Blocks to each Product (Pieris’ Contribution and Servier’s Contribution) and that such responsibility, including any milestones or royalties due in the case of a Building Block licensed from a Third Party (“ Licensed Building Block ”), continues even in the event that Pieris or Servier ceases its Development or Commercialization (including Manufacture thereof for purposes of such Development or Commercialization, as applicable) of a Product to the extent permitted under Section 5.2 of the Agreement (Dropped Products) or in the event that the Agreement is terminated with respect to a Product under Section 12.2 of the Agreement (terminated Products).

(v) Non-Solicitation . During the Term and for twelve (12) months thereafter, Executive agrees that, without the prior written consent of the Board he shall not, on his own behalf or on behalf of any person or entity, directly or indirectly, (a) solicit for employment any employee who has been employed by the Company or any Affiliate at any time during the twelve (12) months immediately preceding such solicitation or offer or (b) solicit for the business of or provide services to any client, customer, or vendor of the Company or any Affiliate for which he or any subordinate provided services during the Term.

In the event of the breach or threatened breach by

Executive of any of such restrictions, the Company shall be entitled to apply to any court of competent jurisdiction for an injunction restraining Executive for such breach or threatened breach, including, but not limited to, a civil seizure order under the Defend Trade Secrets Act; provided that the right of the Company to apply for an injunction shall not be construed as prohibiting the Company from pursuing any other available remedies for such breach or threatened breach. In the event that, notwithstanding the foregoing, a restriction, or any portion thereof, contained in Section 4(a) is deemed to be unreasonable by a court of competent jurisdiction, whether due to the passage of time, change of circumstances or otherwise, Executive and the Company agree that such restriction, or portion thereof, shall be modified in order to make it reasonable and shall be enforced accordingly.

(“ JAMS ”) under the applicable JAMS employment rules. By agreeing to this arbitration procedure, both Executive and the Company waive the right to resolve any such dispute through a trial by jury or judge or administrative proceeding . The arbitrator shall: (i) have the authority to compel adequate discovery for the resolution of the dispute and to award such relief as would otherwise be permitted by law; and (ii) issue a written arbitration decision, to include the arbitrator’s essential findings and conclusions and a statement of the award. The arbitrator shall be authorized to award any or all remedies that Executive or the Company would be entitled to seek in a court of law. The Company shall pay all JAMS’ arbitration fees in excess of the amount of court fees that would be required if the dispute were decided in a court of law. Nothing in this Agreement is intended to prevent either Executive or the Company from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration. Notwithstanding the foregoing, Executive and the Company each have the right to resolve any issue or dispute over intellectual property rights by Court action instead of arbitration.
