NOVAVAX, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
March 31, 2022
(unaudited)
Note 1 – Organization and Business

Novavax, Inc. (“Novavax,” and together with its wholly owned subsidiaries, the “Company”) is a biotechnology company that promotes improved global health through the discovery, development, and commercialization of innovative vaccines to prevent serious infectious diseases. The Company’s coronavirus vaccine, NVX-CoV2373, and its lead influenza vaccine candidate, a quadrivalent influenza vaccine, previously known as NanoFlu, are genetically engineered, three-dimensional nanostructures of recombinant proteins critical to disease pathogenesis and may elicit differentiated immune responses, which may be more efficacious than naturally occurring immunity or traditional vaccines. NVX-CoV2373 and the Company’s influenza vaccine include the use of the Company's proprietary Matrix-M adjuvant.

As of March 31, 2022, the Company had received approval, interim authorization, provisional approval, conditional marketing authorization, and emergency use authorization (“EUA”) from multiple regulatory authorities globally for NVX-CoV2373, including by the World Health Organization (“WHO”), as well as the European Medicines Agency's (“EMA”) and the United Kingdom's Medicines and Healthcare products Regulatory Agency (“MHRA”), both of which are considered regulatory authorities that apply stringent standards and meet the WHO standards for quality, safety, and efficacy in their regulatory review process.

During the three months ended March 31, 2022, the Company commenced commercial shipments of NVX-CoV2373 doses, under the brand name, Nuvaxovid™.
Note 2 – Summary of Significant Accounting Policies
Basis of Presentation
The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. The consolidated financial statements are unaudited, but include all adjustments (consisting of normal recurring adjustments) that the Company considers necessary for a fair presentation of the financial position, operating results, comprehensive loss, changes in stockholders’ equity (deficit), and cash flows, respectively, for the periods presented. Although the Company believes that the disclosures in these unaudited consolidated financial statements are adequate to make the information presented not misleading, certain information and footnote information normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted as permitted under the rules and regulations of the United States Securities and Exchange Commission (“SEC”).
The unaudited consolidated financial statements include the accounts of Novavax, Inc. and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Accumulated other comprehensive income included a foreign currency translation loss of $1.3 million and $1.4 million as of March 31, 2022 and December 31, 2021, respectively.
The accompanying unaudited consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2021. Results for this or any interim period are not necessarily indicative of results for any future interim period or for the entire year. The Company operates in one business segment.

Reclassifications
Certain amounts reported in prior periods have been reclassified to conform to current period financial statement presentation. These reclassifications have no material effect on previously reported financial position, cash flows, or results of operations.
Use of Estimates
The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from those estimates.
Revenue Recognition - Product Sales

Product sales are associated with our NVX-CoV2373 supply agreements, sometimes referred to as advance purchase agreements (“APAs”), with various international governments. The Company recognizes revenue from product sales based on the transaction price per dose calculated in accordance with Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (Topic 606) when control of the product transfers to the customer and customer acceptance has occurred, unless such acceptance provisions are deemed perfunctory. If an APA includes a term that may have the effect of decreasing the price per dose of previously delivered shipments, the Company constrains the price until it is probable that a significant reversal in revenue recognized will not occur.
Cost of Sales
Cost of sales includes cost of raw materials, production, and manufacturing overhead costs associated with the Company’s product sales during the period. Cost of sales also includes adjustments for excess, obsolete, or expired inventory to the extent management determines that the cost cannot be recovered based on estimates about future demand. Cost of sales does not include certain expenses related to raw materials, production, and manufacturing overhead costs which were expensed as described under the caption “Inventory” below.
Inventory

Inventory is recorded at the lower of lease-adjusted standard cost or net realizable value under the First In, First Out (“FIFO”) methodology, taking into consideration the expiration of the inventory item. The Company determines cost using a standard cost method, which approximates average cost. Average cost consists primarily of costs associated with the purchase of raw materials, the cost of manufacturing goods, including the services and products of third-party suppliers, and the application of manufacturing overhead. The Company utilizes third-party contract manufacturing organizations (“CMOs”), contract development and manufacturing organizations (“CDMOs”) and other suppliers and service organizations to support the procurement and processing of raw materials, management of inventory, packaging, and the delivery process. Adjustments to reduce the cost of inventory to its net realizable value, if required, are made for estimated excess, obsolete, or expired inventory through cost of goods sold.

Prior to initial regulatory authorization for its product candidates, the Company expenses costs relating to raw materials, production, and manufacturing overhead costs as research and development expenses in the consolidated statements of operations, in the period incurred. Subsequent to initial regulatory authorization for a product candidate, the Company capitalizes the costs of production for a particular supply chain as inventory when the Company determines that it has a present right to the economic benefit associated with the product.

Recent Accounting Pronouncements
Not Yet Adopted
In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), with amendments in 2018, 2019, and 2020. The ASU sets forth a “current expected credit loss” (“CECL”) model that requires companies to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable supportable forecasts. ASU 2016-13 applies to financial instruments that are not measured at fair value, including receivables that result from revenue transactions. The ASU is effective for the Company beginning on January 1, 2023. Management is currently evaluating the effect of the guidance and does expect it to have a material impact on the Company’s consolidated financial statements.
Adopted
In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which simplified the accounting for certain financial instruments with characteristics of liabilities and equity, including certain convertible instruments and contracts in an entity’s own equity. Specifically, the new standard removed the separation models required for convertible debt with cash conversion features and convertible instruments with beneficial conversion features. It also removed certain settlement conditions that are currently required for equity contracts to qualify for the derivative scope exception and simplified the diluted earnings per share calculation for convertible instruments. The Company adopted ASU 2020-06 on January 1, 2022 using a modified retrospective approach, which did not have a material impact on the Company’s consolidated financial statements.

Note 10 - Leases

During the first quarter of 2022, the Company evaluated the impact of changes in facts and circumstances on its CMOs and CDMOs agreements that had previously been determined to represent embedded lease arrangements. The Company concluded that the impact resulted in the modification of existing leases and, in accordance with its policy, the Company remeasured and reallocated the remaining consideration in the contracts and reassessed the lease classification as of the effective date of the modification. As a result, the Company recognized a Right-Of-Use (“ROU”) asset and a corresponding long-term operating lease liability of $10.4 million on the remeasurement of one of its long-term supply agreements using an incremental borrowing rate of 2.4%. The Company expensed the ROU asset since it relates to research and development activities for the development of NVX-CoV2373 for which the Company does not have an alternative future use. Modifications to leases with a lease term of 12 months or less at the commencement date did not result in a change in lease classification and in accordance with the Company's election, it applied the practical expedient in ASC 842 to recognize lease payments as an expense on a straight-line basis over the modified lease term.
During the three months ended March 31, 2022 and 2021, the Company recognized a short-term lease expense of $78.1 million and $127.6 million, respectively, related to its embedded leases and expensed $10.4 million and $1.0 million, respectively, of ROU assets that represented assets acquired for research and development activities that did not have an alternative future use at the commencement or modification of the lease. During the three months ended March 31, 2022 and 2021, the Company recognized $1.1 million and $2.1 million of interest expense, respectively, on its finance lease liabilities.
During 2020, the Company entered into a lease agreement for the premises located at 700 Quince Orchard Road, Gaithersburg, Maryland (“700QO”). The lease is for approximately 170,000 square feet of space that the Company intends to use for manufacturing, research and development, and offices. The term of the lease is 15 years with options to extend the lease. The lease provides for an annual base rent of $5.8 million that is subject to future rent increases and obligates the Company to pay building operating costs. During the three months ended March 31, 2022, the Company obtained the right to direct the use of, and obtain substantially all of the benefit from, the third floor of the premises and recognized a ROU asset of $47.8 million and related lease obligation for the combined third floor and land lease as the lease commencement date for accounting purposes had occurred.

Note 11 – Debt
Convertible Notes
The Company incurred approximately $10.0 million of debt issuance costs during the first quarter of 2016 relating to the issuance of $325 million aggregate principal amount of convertible senior unsecured notes that will mature on February 1, 2023 (the “Notes”), which were recorded as a reduction to the Notes on the consolidated balance sheet. The $10.0 million of debt issuance costs is being amortized and recognized as additional interest expense over the seven-year contractual term of the Notes on a straight-line basis, which approximates the effective interest rate method.
Total convertible notes payable consisted of the following at (in thousands):

Note 12 – Stockholders' Equity (Deficit)
During the three months ended March 31, 2022, the Company sold 2.2 million of shares of its common stock resulting in net proceeds of approximately $179 million, under its most recent At Market Issuance Sales agreement entered in June 2021 (the “June 2021 Sales Agreement”), which allows it to issue and sell up to $500 million in gross proceeds of shares of its common stock. As of March 31, 2022, the remaining balance under the June 2021 Sales Agreement was approximately $318 million.
During the three months ended March 31, 2021, the Company sold 2.6 million shares of its common stock resulting in net proceeds of approximately $565 million, under its various At Market Issuance Sales agreements.
Note 13 – Stock-Based Compensation
Equity Plans
The 2015 Stock Incentive Plan, as amended (“2015 Plan”), was approved at the Company's annual meeting of stockholders in June 2015. Under the 2015 Plan, equity awards may be granted to officers, directors, employees, and consultants of and advisors to the Company and any present or future subsidiary.
The 2015 Plan authorizes the issuance of up to 12.4 million shares of common stock under equity awards granted under the 2015 Plan. All such shares authorized for issuance under the 2015 Plan have been reserved. The 2015 Plan will expire on March 4, 2025.
The Amended and Restated 2005 Stock Incentive Plan (“2005 Plan”) expired in February 2015 and no new awards may be made under such plan, although awards will continue to be outstanding in accordance with their terms.
13


The 2015 Plan permits and the 2005 Plan permitted the grant of stock options (including incentive stock options), restricted stock, stock appreciation rights, and restricted stock units. In addition, under the 2015 Plan, unrestricted stock, stock units, and performance awards may be granted. Stock options and stock appreciation rights generally have a maximum term of ten years and may be or were granted with an exercise price that is no less than 100% of the fair market value of the Company's common stock at the time of grant. Grants of stock options are generally subject to vesting over periods ranging from one to four years.
The Company recorded all stock-based compensation expense in the consolidated statements of operations as follows (in thousands):

As of March 31, 2022, there was approximately $239 million of total unrecognized compensation expense related to unvested stock options, SARs, RSUs, and the ESPP. This unrecognized non-cash compensation expense is expected to be recognized over a weighted-average period of approximately one year. This estimate does not include the impact of other possible stock-based awards that may be made during future periods.
The aggregate intrinsic value represents the total intrinsic value (the difference between the Company's closing stock price on the last trading day of the period and the exercise price, multiplied by the number of in-the-money stock options and SARs) that would have been received by the holders had all stock option and SAR holders exercised their stock options and SARs on March 31, 2022. This amount is subject to change based on changes to the closing price of the Company's common stock. The aggregate intrinsic value of stock options and SARs exercises and vesting of RSUs for the three months ended March 31, 2022 and 2021 was approximately $5.6 million and $81.5 million, respectively.

Employee Stock Purchase Plan
The Employee Stock Purchase Plan, as amended (the “ESPP”), was approved at the Company's annual meeting of stockholders in June 2013. The ESPP currently authorizes an aggregate of 600,000 shares of common stock to be purchased. The ESPP allows employees to purchase shares of common stock of the Company at each purchase date through payroll deductions of up to a maximum of 15% of their compensation, at 85% of the lesser of the market price of the shares at the time of purchase or the market price on the beginning date of an option period (or, if later, the date during the option period when the employee was first eligible to participate). As of March 31, 2022, there were 137,139 shares available for issuance under the ESPP.
The ESPP is considered compensatory for financial reporting purposes. As such, the fair value of ESPP shares was estimated at the date of grant using the Black-Scholes option-pricing model with the following assumptions:

Note 14 – Income Taxes

The Company evaluates the available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit use of the existing deferred tax assets. A significant piece of objective evidence evaluated was the cumulative loss incurred over the three-year period ended March 31, 2022 and that the Company has historically generated pretax losses. Such objective evidence limits the ability to consider other subjective evidence, such as projections for future growth. On the basis of this evaluation, as of March 31, 2022, the Company continued to maintain a full valuation allowance against its deferred tax assets, except to the extent Net Operating Losses (“NOLs”) were used to reduce taxable income during the quarter. The Company’s remaining U.S. Federal NOLs are subject to limitation in accordance with the 2017 Tax Cuts and Jobs Act, which limits allowable NOL deductions to 80% of federal taxable income.
The Company recognized federal and state income tax expense of $0.6 million, in total, for the three months ended March 31, 2022 and did not recognize federal or state income tax expense for the three months ended March 31, 2021. During the three months ended March 31, 2022 and 2021, the Company recognized $2.1 million and $3.0 million, respectively, of income tax expense related to foreign withholding tax on royalties.

Legal Matters
On November 12, 2021, Sothinathan Sinnathurai filed a purported securities class action in the U.S. District Court for the District of Maryland against the Company and certain members of senior management, captioned Sothinathan Sinnathurai v. Novavax, Inc., et al., No. 8:21-cv-02910-TDC (the “Sinnathurai Action”). On January 26, 2022, the court entered an order designating David Truong, Nuggehalli Balmukund Nandkumar, and Jeffrey Gabbert as co-lead plaintiffs in the Sinnathurai Action. The co-lead plaintiffs filed a consolidated amended complaint on March 11, 2022, alleging that the defendants made certain purportedly false and misleading statements concerning the Company’s ability to manufacture NVX-CoV2373 on a commercial scale and to secure the vaccine’s regulatory approval. The amended complaint defines the purported class as those stockholders who purchased the Company’s securities between February 24, 2021 and October 19, 2021. On April 25, 2022, defendants filed a motion to dismiss the consolidated amended complaint.
After the Sinnathurai Action was filed, three derivative lawsuits were filed and are currently pending in the U.S. District Court for the District of Maryland: Robert E. Meyer v. Stanley C. Erck, et al., No. 8:21-cv-02996-TDC (the “Meyer Action”), Shui Shing Yung v. Stanley C. Erck, et al., No. 8:21-cv-03248-TDC (the “Yung Action”), and William Kirst, et al. v. Stanley C. Erck, et al., No. 8:22-cv-00024-TDC (the “Kirst Action”). The derivative lawsuits name members of the board of directors and certain members of senior management as defendants. The company is deemed a nominal defendant. The plaintiffs assert derivative claims arising out of substantially the same alleged facts and circumstances as the Sinnathurai Action. Collectively, the derivative complaints assert claims for breach of fiduciary duty, insider selling, unjust enrichment, violation of federal securities law, abuse of control, waste, and mismanagement. Plaintiffs seek declaratory and injunctive relief, as well as an award of monetary damages and attorneys’ fees. The Company removed the Kirst Action from the Circuit Court for Montgomery County, Maryland, shortly after the case was filed. On February 7, 2022, the plaintiffs in the Kirst Action filed a motion to remand the case to state court. The Company has opposed the remand motion. The parties finished briefing the remand motion on March 8, 2022, and await the Court’s decision. On February 4, 2022, the Court entered an order consolidating the Meyer and Yung Actions (the “Consolidated Derivative Action”). The plaintiffs in the Consolidated Derivative Action filed their consolidated derivative complaint on April 25, 2022. The parties to the Consolidated Derivative Action intend to file a stipulation and proposed order to temporarily stay all proceedings and deadlines in the Consolidated Derivative Action.

On March 29, 2022, Par Sterile Products, LLC (“Par”) submitted a demand for arbitration against the Company with the American Arbitration Association, alleging that the Company breached certain provisions of the Manufacturing and Services Agreement (“MSA”) that the Company entered into with Par in September 2020 to provide fill-finish manufacturing services for NVX-CoV2373. The matter is at a preliminary stage and therefore the potential loss is not reasonably estimable. While the Company maintains that no breach of the MSA has occurred and intends to vigorously defend the matter, if the final resolution of the matter is adverse to the Company, it could have a material impact on the Company's financial position, results of operations, or cash flows.
The Company is also involved in various legal proceedings arising in the normal course of business. Although the outcomes of these legal proceedings are inherently difficult to predict, management does not expect the resolution of these legal proceedings to have a material adverse effect on the Company's financial position, results of operations, or cash flows.

Overview

Novavax, Inc., together with our wholly-owned subsidiaries, is a biotechnology company that promotes improved health globally through the discovery, development, and commercialization of innovative vaccines to prevent serious infectious diseases around the world. Our proprietary recombinant technology platform harnesses the power and speed of genetic engineering to efficiently produce highly immunogenic nanoparticle vaccines designed to address urgent global health needs.

Our vaccine candidates are genetically engineered nanostructures of conformationally correct recombinant proteins that mimic those found on natural pathogens. This technology enables the immune system to recognize the right target proteins from different angles and develop protective antibodies. We believe that our vaccine technology may lead to the induction of a differentiated immune response that may be more efficacious than naturally occurring immunity or other vaccine approaches. Our vaccine candidates also incorporate our proprietary saponin-based Matrix-M™ adjuvant to enhance the immune response and stimulate higher levels of functional antibodies and induce a cellular immune response.

We have developed a COVID-19 vaccine (“NVX-CoV2373,” “Nuvaxovid™,” “Covavax”), and are developing an influenza vaccine, a COVID-19-Influenza Combination vaccine, and additional vaccine candidates. NVX-CoV2373 has received approval, interim authorization, provisional approval, conditional marketing authorization (“CMA”), and emergency use authorization (“EUA”) from multiple regulatory authorities globally. In addition to COVID-19 and seasonal influenza, our other areas of focus include respiratory syncytial virus (“RSV”) and malaria.

Technology Overview

We believe our recombinant nanoparticle vaccine technology together with our proprietary Matrix-M™ adjuvant is well-suited for the development of vaccine candidates targeting a broad scope of respiratory and other emerging infectious diseases at scale.

Recombinant Nanoparticle Vaccine Technology

Once a pathogenic threat has been identified, the genetic sequence encoding the antigen is selected for subsequent use in developing the vaccine construct. The genetic sequence may be optimized to enhance protein stability or confer resistance to degradation. This genetic construct is inserted into the baculovirus Spodoptera frugiperda (“Sf9/BV”) insect cell-expression system, which enables efficient, large-scale expression of the optimized protein. The Sf9/BV system produces proteins that are properly folded and modified – which can be critical for functional, protective immunity – as the vaccine antigen. Protein antigens are purified and organized around a polysorbate-based nanoparticle core, in a configuration that resembles their native presentation. This results in a highly immunogenic nanoparticle that is ready to be formulated with Matrix-M adjuvant.

Matrix-M™ Adjuvant

Our proprietary Matrix-M™ adjuvant has been a key differentiator within our platform. This adjuvant has demonstrated potent, well-tolerated, and durable efficacy by stimulating the entry of antigen presenting cells (“APCs”) into the injection site and enhancing antigen presentation in local lymph nodes. This in turn activates APCs, T-cell and B-cell populations, plasma cells, and high affinity antibodies, thereby boosting immune response. This potent mechanism of action enables a lower dose of antigen required to achieve the desired immune response and we believe thereby contributes to increased vaccine supply and manufacturing capacity. These immune-boosting and dose-sparing capabilities contribute to the adjuvant’s highly unique profile.

NVX-CoV2373 Regulatory and Licensure

We continue to make progress in advancing NVX-CoV2373 toward regulatory approvals. We have received numerous authorizations globally, which collectively have the potential to reach over six billion individuals. To date, we have received approval, interim authorization, provisional approval, CMA, and EUA for both adult and adolescent populations, and we expect to initiate additional rolling submissions worldwide. We continue to work closely with governments, regulatory authorities, and non-governmental organizations in our commitment to facilitate equitable global access to our COVID-19 vaccine.

For the territories in which our vaccine has gained authorization, NVX-CoV2373 is marketed under the brand name of Nuvaxovid™ COVID-19 Vaccine (SARS-CoV-2 rS [Recombinant, adjuvanted]) or as Covovax™ (manufacturing and commercialization by the Serum Institute of India Pvt. Ltd. (“SIIPL”)).

Clinical Pipeline

Our clinical pipeline encompasses vaccine candidates spanning multiple therapeutic areas including coronavirus, seasonal influenza, RSV, and Matrix-MTM adjuvant collaborations for the prevention of malaria. Our COVID-19 vaccine candidate, NVX-CoV2373, is our leading product, having received approval, interim authorization, provisional approval, CMA, and EUA from multiple regulatory authorities globally. We advanced NVX-CoV2373 through two pivotal Phase 3 clinical trials that demonstrated high efficacy against both the original COVID-19 strain and commonly circulating COVID-19 variants of concern (“VoC”), while maintaining a favorable safety profile. We also advanced our influenza vaccine through a Phase 3 clinical trial, which demonstrated positive top-line results and achieved statistical significance in key secondary endpoints. We initiated a trial of a COVID-19-Influenza Combination vaccine (“CIC”) consisting of our influenza vaccine and NVX-CoV2373. In April 2022, we announced initial results from Phase 1/2 clinical trial of CIC demonstrating that formulating the combination vaccine is well-tolerated and immunogenic. Modeling results showed that combined formulation has the potential to reduce total antigen amount by up to 50% overall, optimizing production and delivery. Additionally, we remain interested in further development of our RSV Program for respiratory syncytial virus fusion (F) protein nanoparticle vaccine candidate (“RSV F Vaccine”). Ongoing Phase 3 trials are being conducted by our partner, Jenner Institute, University of Oxford, for R21, a malaria candidate currently under development by the University of Oxford in partnership with SIIPL, which is formulated using our Matrix-M adjuvant.

We remain focused on bringing our NVX-CoV2373 vaccine candidate to market following global regulatory authorizations. Through ongoing booster studies in our clinical trials, as well as the development of COVID-19 variant strain vaccine candidates, we continue to collect data to characterize and improve vaccine performance. We expect to leverage these clinical insights to advance the use and additional regulatory approvals of our COVID-19 vaccine for both primary vaccination around the globe, to use within a booster setting, and for the pediatric population amidst the ongoing and evolving COVID-19 pandemic.

The pipeline chart below summarizes the core clinical and preclinical development programs that we are focusing on in the near-term.

Total revenue$703,971 $447,229 $256,742 
Revenue for the three months ended March 31, 2022 was $704.0 million as compared to $447.2 million for the same period in 2021, an increase of $256.7 million. Revenue for the three months ended March 31, 2022 was primarily comprised of revenue from product sales of NVX-CoV2373 and, to a lesser extent, revenue for services performed under the agreement with the U.S. government partnership formerly known as OWS (“OWS Agreement”). Revenue for the three months ended March 31, 2021 was primarily comprised of revenue for services performed under the OWS Agreement and our funding agreements with CEPI. The increase in revenue was due to the commencement of product sales of NVX-CoV2373, partially offset by decreased development activities under the OWS Agreement as we approach anticipated commercialization of NVX-CoV2373.
We expect revenue in 2022 to significantly increase as compared to 2021 due to product sales of NVX-CoV2373 under various supply agreements, sometimes referred to as advance purchase agreements (“APAs”), as a result of multiple global regulatory approvals, royalties from the sale of NVX-CoV2373 under our supply and license agreements with strategic partners to supply NVX-CoV2373 in their specified territories where we are entitled to receive royalties from such sales, and our NVX-CoV2373 program, which we anticipate will continue to be funded by OWS and other revenue sources.

Cost of Sales
Cost of sales was $15.2 million, or 3% of product sales, for the three months ended March 31, 2022. Prior to receiving approval, we expensed manufacturing costs as research and development expenses. After receiving approval, we capitalize the costs of production for a particular supply chain when we determine that we have a present right to the economic benefit associated with the product. While we tracked the quantities of our manufactured vaccine product and components, we did not track pre-approval manufacturing costs and therefore the manufacturing cost of our pre-launch inventory produced prior to approval is not reasonably determinable. However, based on our expectations for future manufacturing costs to produce our vaccine product and components inventory, we estimate that approximately $0.7 billion of commercial inventory was expensed prior to approval. We expect to utilize the majority of our reduced-cost inventory during 2022. If inventory sold for the three months ended March 31, 2022 was valued at expected standard cost, adjusted cost of sales for the period would have been approximately $160 million, or 27% of product sales, an adjustment of $145 million. The cost of sales as a percentage of product sales may fluctuate in the future as a result of changes to our customer mix or standard costs.
Research and Development Expenses
Research and development expenses decreased to $383.5 million for the three months ended March 31, 2022 as compared to $592.7 million for the three months ended March 31, 2021, a decrease of $209.2 million primarily due to research and development of NVX-CoV2373, as summarized in the table below (in millions):

Research and development expenses for NVX-CoV2373 for the three months ended March 31, 2022, and March 31, 2021 included approximately $21.0 million and $22.8 million, respectively, related to the acceleration of manufacturing costs for leases that we determined were embedded in multiple manufacturing supply agreements with Contract Manufacturing Organizations (“CMOs”) and contract manufacturing and development organizations (“CDMOs”). For 2022, we expect total research and development expenses to decrease as compared to 2021. The decline in 2022 is anticipated to result from expected capitalization of manufacturing costs during 2022 that were previously recognized as research and development expenses in prior periods, partially offset by research and development expenses related to increased clinical activities as we continue to develop our NVX-CoV2373 and other programs.
Selling, General, and Administrative Expenses
Selling, general, and administrative expenses increased to $96.0 million for the three months ended March 31, 2022 from $63.2 million for the same period in 2021, an increase of $32.8 million. The increase in selling, general, and administrative expenses is primarily due to an increase in professional fees in support of our NVX-CoV2373 program. For 2022, we expect selling, general, and administrative expenses to increase significantly due to increased activities related to supporting our NVX-CoV2373 program and increases in employee-related costs and professional fees.

We had total other expense, net, of $3.2 million for the three months ended March 31, 2022 as compared to $11.1 million for the same period in 2021. In the three months ended March 31, 2021, we recorded a $5.9 million loss on the intercompany loan with Novavax CZ due to changes in the foreign exchange rates.
Income Tax Expense
We recognized federal and state income tax expense of $0.6 million, in total, for the three months ended March 31, 2022 and did not recognize federal or state income tax expense for the three months ended March 31, 2021. During the three months ended March 31, 2022 and 2021, we recognized $2.1 million and $3.0 million, respectively, of income tax expense related to foreign withholding tax on royalties.

The change in net income (loss) was primarily due to the commencement of commercial sales of NVX-CoV2373, partially offset by decreased revenue under the OWS Agreement.
The increase in weighted average shares outstanding for the three months ended March 31, 2022 is primarily a result of sales of our common stock and exercises of stock-based awards in 2022 and 2021.
Liquidity Matters and Capital Resources

Our future capital requirements depend on numerous factors including, but not limited to, revenue from our product sales and royalties under licensing arrangements with our strategic partners; funding under our grant agreements; our projected activities related to the development and commercial support of NVX-CoV2373 and variant candidates, including significant commitments under various CRO, CMO, and CDMO agreements; the progress of preclinical studies and clinical trials; the time and costs involved in obtaining regulatory approvals; the costs of filing, prosecuting, defending, and enforcing patent claims and other intellectual property rights; and other manufacturing, sales, and distribution costs. We plan to continue developing other vaccines and product candidates, such as our influenza vaccine candidate and potential combination vaccines candidates, which are in various stages of development.

We have entered into supply agreements, sometimes referred to as APAs, with Gavi, the Vaccine Alliance (“Gavi”); the European Commission; and various countries globally. We also have grant and license agreements. As of March 31, 2022, the aggregate amount of the transaction price allocated to performance obligations that were unsatisfied (or partially unsatisfied), excluding amounts related to sales-based royalties under the license agreements, was approximately $7 billion. The timing to fulfill performance obligations related to grant agreements will depend on the results of our research and development activities, including clinical trials, receipt of US marketing authorization, and delivery of doses. The timing to fulfill performance obligations related to supply agreements will depend on timing of product manufacturing, receipt of marketing authorizations, and delivery of doses. The supply agreements typically contain terms that include upfront payments intended to assist us in funding investments related to building out and operating our manufacturing and distribution network, among other expenses, in support of our global supply commitment, and are applied to billings upon delivery of NVX-CoV2373. Such upfront payments generally become non-refundable upon our achievement of certain development, regulatory, and commercial milestones. Certain of the supply agreements may be terminated by the counterparty in the event we fail to achieve requisite regulatory approval for NVX-CoV2373 in relevant jurisdictions within established time periods. Failure to successfully develop and commercialize NVX-CoV2373 and failure to meet regulatory milestones or product volume or delivery timing obligations under our supply agreements may require us to refund significant portions of the prepayments or reduce payments, which could have a material and adverse effect on our financial condition. In addition, we continue to assess our manufacturing needs and intend to modify our global manufacturing footprint consistent with our contractual obligations to supply, and anticipated demand for, NVX-CoV2373, and in doing so recognize that significant costs may be incurred.
28



Under the terms of our contracted supply commitment with Gavi, which includes the supply obligation of our licensed partner, SIIPL, 1.1 billion doses of NVX-CoV2373 are to be made available to countries participating in the COVAX Facility, which was established to allocate and distribute vaccines equitably to participating countries and economies. The Novavax portion is a supply agreement that contemplates that we will manufacture and distribute 350 million doses. Under that agreement with Gavi, we received an upfront payment of $350 million from Gavi in 2021 and an additional payment of $350 million in the first quarter of 2022 related to our achieving WHO EUL. Although Novavax is prepared to deliver the quantities of NVX-CoV2373 doses to Gavi under the terms of our supply agreement, we were recently notified by Gavi of their intent to seek to revise the number and timing of doses of NVX-CoV2373 supplied by Novavax under such agreement. To date, Novavax has not received an order from Gavi and the timing and quantities of future orders to deliver NVX-COV2373 to the COVAX facility are unclear.

We have also entered into supply and license agreements with strategic partners, such as SIIPL in India, Takeda in Japan, and SK bioscience in the Republic of Korea, that allow them to supply NVX-CoV2373 in their specified territories and under which we are entitled to receive royalties primarily from their sales of NVX-CoV2373. During the three months ended March 31, 2022, we recognized royalties of $7.4 million under these licensing arrangements.

In the three months ended March 31, 2022, we primarily funded our operations with cash and cash equivalents, upfront payments under APAs, revenue from product sales, royalties under licensing arrangements with our strategic partners, and proceeds from the sale of common stock together with revenue under the OWS Agreement that supports our NVX-CoV2373 vaccine development activities. We anticipate our future operations to be funded by revenue from product sales, royalties under licensing arrangements with our strategic partners, our cash and cash equivalents, upfront payments under our APAs, revenue under our OWS Agreement, and other potential funding sources.
As of March 31, 2022, we had $1.6 billion in cash and cash equivalents and restricted cash as compared to $1.5 billion as of December 31, 2021.
The following table summarizes cash flows for the three months ended March 31, 2022 and 2021 (in thousands):

Net cash used in operating activities was $88.5 million for the three months ended March 31, 2022, as compared to net cash provided by operating activities of $663.1 million for the same period in 2021. The decrease in cash provided is primarily due to the application of upfront payments under APAs resulting from sales of NVX-CoV2373 during the three months ended March 31, 2022 as compared to an increase in cash due to the receipt of upfront payments under APAs during the three months ended March 31, 2021.
During the three months ended March 31, 2022 and 2021, our investing activities consisted primarily of capital expenditures and maturities and sale of marketable securities, net of purchases. Capital expenditures for the three months ended March 31, 2022 and 2021 were $16.8 million and $13.8 million, respectively. For 2022, we expect our capital expenditures to continue to increase due to further development activities for our NVX-CoV2373 program, including the additional build-out of research and development and manufacturing facilities and related equipment, and the build-out of our new corporate office facility.
Our financing activities consisted primarily of sales of our common stock under our At Market Issuance Sales Agreements, payments of finance lease liabilities, and exercise of stock-based awards. In the three months ended March 31, 2022 and 2021, we received net proceeds of approximately $179 million and $565 million, respectively, from selling shares of common stock through our At Market Issuance Sales Agreements.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

We are subject to certain risks that may affect our results of operations, cash flows, and fair values of assets and liabilities, including volatility in foreign currency exchange rates and interest rate movements.

Foreign Currency Exchange Risk

Although we are headquartered in the U.S., our results of operations, including our foreign subsidiaries’ operations, are subject to foreign currency exchange rate fluctuations, primarily the U.S. dollar against the Euro, Pound Sterling, Swedish Krona, and Czech Koruna. This exchange exposure may have a material effect on our cash flow and results of operations, particularly in cases of revenue generated under APAs that include provisions that impact our and our counterparty’s currency exchange exposure. To date, we have not entered into any foreign currency hedging contracts, although we may do so in the future.

We also face foreign currency exchange exposure that arises from translating the results of our global operations to the U.S. dollar at exchange rates that have fluctuated from the beginning of the period. While the financial results of our global activities are reported in U.S. dollars, the functional currency of our foreign subsidiaries is their respective local currency. Fluctuations in the foreign currency exchange rates of the countries in which we do business will affect our operating results, often in ways that are difficult to predict. A 10% decline in the foreign exchange rates (primarily against the U.S. dollar) relating to our foreign consolidated subsidiaries would result in a decline of stockholders’ equity of approximately $38 million as of March 31, 2022.

Market and Interest Rate Risk

The primary objective of our investment activities is preservation of capital, with the secondary objective of maximizing income.

Our exposure to market risk is primarily confined to our investment portfolio, which historically has been classified as available-for-sale. We do not believe that a change in the market rates of interest would have any significant impact on the realizable value of our investment portfolio. Changes in interest rates may affect the investment income we earn on our marketable securities when they mature and the proceeds are reinvested into new marketable securities and, therefore, could impact our cash flows and results of operations.

Interest and dividend income is recorded when earned and included in investment income. Premiums and discounts, if any, on marketable securities are amortized or accreted to maturity and included in investment income. The specific identification method is used in computing realized gains and losses on the sale of our securities.

Our Notes have a fixed interest rate, and we have no additional material debt. As such, we do not believe that we are exposed to any material interest rate risk as a result of our borrowing activities.
Item 4.    Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Our management, with the assistance of our chief executive officer and chief financial officer, has reviewed and evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of March 31, 2022. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving such control objectives. Based on the evaluation of our disclosure controls and procedures as of March 31, 2022, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.
30


Changes in Internal Control over Financial Reporting

Our management, including our chief executive officer and chief financial officer, have evaluated changes in our internal control over financial reporting that occurred during the quarter ended March 31, 2022, and have concluded that there have been no changes in our internal control over financial reporting 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
Stockholder Litigation

On November 12, 2021, Sothinathan Sinnathurai filed a purported securities class action in the U.S. District Court for the District of Maryland against Novavax and certain members of senior management, captioned Sothinathan Sinnathurai v. Novavax, Inc., et al., No. 8:21-cv-02910-TDC (the “Sinnathurai Action”). On January 26, 2022, the court entered an order designating David Truong, Nuggehalli Balmukund Nandkumar, and Jeffrey Gabbert as co-lead plaintiffs in the Sinnathurai Action. The co-lead plaintiffs filed a consolidated amended complaint on March 11, 2022, alleging that the defendants made certain purportedly false and misleading statements concerning the Company’s ability to manufacture NVX-CoV2373 on a commercial scale and to secure the vaccine’s regulatory approval. The amended complaint defines the purported class as those stockholders who purchased Novavax securities between February 24, 2021 and October 19, 2021. On April 25, 2022, defendants filed a motion to dismiss the consolidated amended complaint.

After the Sinnathurai Action was filed, three derivative lawsuits were filed and are currently pending in the U.S. District Court for the District of Maryland: Robert E. Meyer v. Stanley C. Erck, et al., No. 8:21-cv-02996-TDC (the “Meyer Action”), Shui Shing Yung v. Stanley C. Erck, et al., No. 8:21-cv-03248-TDC (the “Yung Action”), and William Kirst, et al. v. Stanley C. Erck, et al., No. 8:22-cv-00024-TDC (the “Kirst Action”). The derivative lawsuits name members of the board of directors and certain members of senior management as defendants. Novavax is deemed a nominal defendant. The plaintiffs assert derivative claims arising out of substantially the same alleged facts and circumstances as the Sinnathurai Action. Collectively, the derivative complaints assert claims for breach of fiduciary duty, insider selling, unjust enrichment, violation of federal securities law, abuse of control, waste, and mismanagement. Plaintiffs seek declaratory and injunctive relief, as well as an award of monetary damages and attorneys’ fees. Novavax removed the Kirst Action from the Circuit Court for Montgomery County, Maryland, shortly after the case was filed. On February 7, 2022, the plaintiffs in the Kirst Action filed a motion to remand the case to state court. The Company has opposed the remand motion. The parties finished briefing the remand motion on March 8, 2022, and await the Court’s decision. On February 4, 2022, the Court entered an order consolidating the Meyer and Yung Actions (the “Consolidated Derivative Action”). The plaintiffs in the Consolidated Derivative Action filed their consolidated derivative complaint on April 25, 2022. The parties to the Consolidated Derivative Action intend to file a stipulation and proposed order to temporarily stay all proceedings and deadlines in the Consolidated Derivative Action.
Par Sterile Products, LLC Arbitration

On March 29, 2022, Par Sterile Products, LLC (“Par”) submitted a demand for arbitration against the Company with the American Arbitration Association, alleging that the Company breached certain provisions of the Manufacturing and Services Agreement (“MSA”) that the Company entered into with Par in September 2020 to provide fill-finish manufacturing services for NVX-CoV2373. The matter is at a preliminary stage and therefore the potential loss is not reasonably estimable. While the Company maintains that no breach of the MSA has occurred and intends to vigorously defend the matter, if the final resolution of the matter is adverse to the Company, it could have a material impact on the Company's financial position, results of operations, or cash flows.
General

We are also involved in various other legal proceedings arising in the normal course of business. Although the outcomes of these other legal proceedings are inherently difficult to predict, we do not expect the resolution of these other legal proceedings to have a material adverse effect on our financial position, results of operations, or cash flows.

Novavax, Inc.
21 Firstfield Road
Gaithersburg, MD 20878

Attention:    [***], Senior Vice President
Subject:    Modification No. 01
Reference:    MCDC Base Agreement No. 2020-530 Dear [***]:
In accordance with the terms and conditions of the referenced MCDC Base Agreement, Modification No. 01 hereby amends the Base Agreement as follows:

DESCRIPTION OF MODIFICATION

1)Article V, Section 5.03, Accounting System Requirements, of the MCDC Base Agreement is hereby amended to read as indicated in bold italics below:

Section 5.03 Accounting System Requirements:

Prior to the submission of invoices, the PAH shall have and maintain an established accounting system which complies with Generally Accepted Accounting Principles (GAAP) and the requirements of this MCDC Base Agreement. The PAH shall ensure that appropriate arrangements have been made for receiving, distributing and accounting for Federal funds under this MCDC Base Agreement. Consistent with this stipulation, an acceptable accounting system will be one in which all cash receipts and disbursements are controlled and documented properly.

For expenditure-based or resource-sharing projects, the capability of the MCDC Member's accounting system will be considered prior to award. Although the Government will not impose requirements that will cause a MCDC Member to revise or alter its existing accounting system, the Government will not enter into a PA that provides for payment based on amounts generated from the MCDC Member's financial or cost records, if the MCDC Member does not have an accounting system capable of identifying the amounts/costs to individual agreements/contracts.

Allowable Costs: Although OTAs are not subject to the FAR, the principles included in FAR Part 31 may be applied to determine price reasonableness for individual projects. MCDC Members who are selected for awards under the Base Agreement may refer to FAR Part 31 for guidance on allowable costs in preparing their final cost proposal for a project award.

2)Article VI, NONTRADITIONAL DEFENSE/COST SHARING of the MCDC Base Agreement is hereby replaced with APPROPRIATE USE OF OTHER TRANSACTION AUTHORITY as indicated below:

Article VI. APPROPRIATE USE OF OTHER TRANSACTION AUTHORITY

In accordance with provisions of 10 USC 2371b, the DoD has authority to enter into transactions other than contracts, grants, or cooperative agreements. The DoD has the authority to make awards that are directly relevant to enhancing the mission effectiveness of military personnel and the supporting platforms, systems, components, or materials proposed to be acquired or developed by the DoD, or the improvement of platforms, systems, components, or materials




in use by the armed forces.

Per 10 U.S.C. § 2371b, each prototype project awarded under this Base Agreement must meet one of the following conditions:

There is at least one nontraditional defense contractor or nonprofit research institution participating to a significant extent in the prototype project.
All significant participants in the transaction, other than the Federal Government, are small businesses (including small businesses participating in a program described under section 9 of the Small Business Act (15
U.S.C. 638)) or nontraditional defense contractors.
At least one third of the total cost of the prototype project is to be paid out of funds provided by sources other than the Federal Government.
The senior procurement executive for the agency determines in writing that exceptional circumstances justify the use of a transaction that provides for innovative business arrangements or structures that would not be feasible or appropriate under a contract, or would provide an opportunity to expand the defense supply base in a manner that would not be practical or feasible under a contract.

Throughout the period of performance of any PA, the AO and AOR will actively monitor projects to ensure compliance with this statutory requirement. The Government will take into account any implementation guidance from the Department of the Army and the Office of the Under Secretary of Defense for Acquisition and Sustainment, which includes but is not limited to, the most recent Other Transactions Guide. The MCDC Member awarded a PA will be given the opportunity to become compliant with this statutory requirement should they be found non-compliant by the AO and AOR and as communicated to the PAH by the CMF. Failure to comply may result in termination.

If significant nontraditional / nonprofit participation cannot be fulfilled, the PAH must provide at least one third cost share of the value of the PA awarded to the PAH. Proposals that fail to comply with this requirement, will not be awarded under the OTA.

Cost Sharing is not required under the OTA for projects that contain significant nontraditional / nonprofit participation. Where both Partiesthe Government and MCDCPAH agree, cost sharing may be considered on a per project basis under terms and conditions to be agreed to by the Partiesthem, and in accordance with the most recent Other Transactions Guide.

Section 21.16 Public Readiness and Emergency Preparedness Act (PREP Act)







The PREP Act authorizes the Secretary of the Department of Health and Human Services (Secretary) to issue a declaration (PREP Act declaration) that provides immunity from liability (except for willful misconduct) for claims of loss caused, arising out of, relating to, or resulting from administration or use of countermeasures to diseases, threats and conditions determined by the Secretary to constitute a present, or credible risk of a future public health emergency to entities and individuals involved in the development, manufacture, testing, distribution, administration, and use of such countermeasures. A PREP Act declaration is specifically for the purpose of providing immunity from liability, and is different from, and not dependent on, other emergency declarations.

Prior to award of individual projects under the program, current declarations will be reviewed by the Government via PHE.gov. If upon review, it is determined that a current declaration is applicable to the project to be awarded, appropriate PREP Act language will be incorporated into the SOW in coordination with the prospective PAH.

The parties hereto agree that this Modification No. 01 shall apply only to new Project Agreements placed under the MCDC Base Agreement and shall not change, increase or otherwise modify the PAH's obligations under any Project Agreements already in place under the MCDC Base Agreement.

Except as provided herein, all Terms and Conditions of the referenced MCDC Base Agreement, Project Agreement, and preceding modifications remain unchanged and in full force and effect.

The Project Agreement Holder is required to sign this document and return to Advanced Technology International to finalize this action.
