NOVAVAX, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
June 30, 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 health globally 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. The Company is developing various variant vaccines, including for Omicron subvariants, and bivalent formulations with prototype vaccine (NVX-CoV2373). The Company has announced preclinical boosting data for NVX-CoV2373, NVX-CoV2515, and bivalent formulations which demonstrated strong antibody levels. The Company is also participating in an ongoing Phase 3 strain change trial to assess safety and antibody responses following primary vaccination with mRNA vaccines.

As of June 30, 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. In July 2022, the Company received emergency use authorization for NVX-CoV2373 from the U.S. Food and Drug Administration (“FDA”).

The Company commenced commercial shipments of NVX-CoV2373 doses under the brand name Nuvaxovid™ in 2022.
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 U.S. 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 $10.9 million and $1.4 million as of June 30, 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.
6

Use of Estimates
The preparation of the consolidated financial statements in conformity with U.S. 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 the Company’s 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; idle capacity; and losses on firm purchase commitments to the extent 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 prior to regulatory authorization as described under the caption “Inventory” below.
Inventory

Inventory is recorded at the lower of 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 the cost of raw materials using moving average costs and the cost of semi-finished and finished goods using a standard cost method adjusted on a periodic basis to reflect the deviation in the actual cost from the standard cost estimate. Standard costs consist primarily of the cost of manufacturing goods, including direct materials, direct labor, 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 sales.

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, 2020 and 2022. 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 not expect it to have a material impact on the Company’s consolidated financial statements.
7

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 3 – Revenue
The Company's accounts receivable included $165.6 million and $419.7 million related to amounts that were billed to customers and $29.0 million and $35.3 million related to amounts which had not yet been billed to customers as of June 30, 2022 and December 31, 2021, respectively. During the six months ended June 30, 2022, changes in the Company's accounts receivables and deferred revenue balances were as follows (in thousands):

(1)    Amount is comprised of $701.5 million and $1.4 billion of current Deferred revenue and $814.6 million and $172.5 million of non-current Deferred revenue as of June 30, 2022 and December 31, 2021, respectively.
The aggregate amount of the transaction price allocated to performance obligations that were unsatisfied (or partially unsatisfied), excluding amounts related to sales-based royalties, was approximately $5 billion as of June 30, 2022. The timing to fulfill performance obligations related to grant agreements will depend on the results of the Company's research and development activities, including clinical trials, and delivery of doses. The timing to fulfill performance obligations related to APAs will depend on timing of product manufacturing, receipt of marketing authorizations for additional indications, delivery of doses based on customer demand, and the ability of the customer to request variant vaccine in place of the prototype NVX-CoV2373 under certain of our APAs. Failure to meet regulatory milestones, product volume, or delivery timing obligations under the Company’s APA agreements may require the Company to refund portions of upfront payments or result in reduced future payments, which could result in a material and adverse effect on our unsatisfied performance obligations. The remaining unfilled performance obligations not related to grant agreements or APAs are expected to be fulfilled in less than 12 months.

U.S. Government Partnership
The Company’s U.S. government partnership consists of an agreement (“the “OWS Agreement”) with Advanced Technology International, the Consortium Management Firm acting on behalf of the Medical CBRN Defense Consortium in connection with the partnership formerly known as Operation Warp Speed (“OWS”). In July 2021, the U.S. government instructed the Company to prioritize alignment with the FDA on the Company's analytic methods before conducting additional U.S. manufacturing and further indicated that the U.S. government would not fund additional U.S. manufacturing until such alignment was made. In June 2022, the U.S. government agreed to the manufacture and delivery of approximately 3 million doses of NVX-CoV2373 under the OWS Agreement as the Company had completed alignment with the FDA’s analytic methods. The Company updated its estimate-at-completion to reflect the impact of this authorization to the recognition of the fixed fee under the contract. In July 2022, the Company formally modified the OWS Agreement to provide for an initial delivery to the U.S. government of approximately 3 million doses of NVX-CoV2373, and the Company modified its existing agreement with the U.S. Department of Defense (“DoD”) to provide for an initial delivery of approximately 0.2 million doses of NVX-CoV2373 (see Note 15).
Royalties and Other
During the three and six months ended June 30, 2022, the Company recognized $1.7 million and $9.2 million, respectively, in revenue related to sales-based royalties. During the three months ended June 30, 2022, the Company recognized a $20.0 million milestone payment upon the first sale of NVX-CoV2373 in Japan. During the three months ended June 30, 2021, the Company recognized $23.5 million in revenue related to sales-based royalties. During the three months ended March 31, 2021, the Company did not recognize any revenue related to sales-based royalties.
Advance Purchase Agreements (APAs)
Under the terms of the Company’s contracted supply commitment with Gavi, which includes the supply obligation of its licensed partner, Serum Institute of India Private Limited (“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 the Company will manufacture and distribute 350 million doses. Under that agreement with Gavi, the Company 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 the Company’s achieving WHO Emergency Use Listing. Although Novavax is prepared to deliver the quantities of NVX-CoV2373 doses to Gavi under the terms of the supply agreement, the Company was notified by Gavi of its intent to seek to revise the number and timing of doses of NVX-CoV2373 supplied by Novavax under such agreement. Furthermore, Gavi may seek partial or full recovery of the prior nonrefundable payments it has made to Novavax. The Company’s position is that Gavi has no contractual right to recover prior nonrefundable payments. 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.
Under the terms of the Company’s SARS-CoV-2 Vaccine Supply Agreement, originally entered into in October 2020 (the “Original UK Supply Agreement”) with The Secretary of State for Business, Energy and Industrial Strategy, acting on behalf of the government of the United Kingdom of Great Britain and Northern Ireland (the “Authority”), the Authority agreed to purchase 60 million doses of NVX-CoV2373. In July 2022, the Company entered into an Amended and Restated SARS-CoV-2 Vaccine Supply Agreement (the “Amended and Restated UK Supply Agreement”) with the Authority, under which the Authority agreed to purchase a minimum of 1 million doses and up to an additional 15 million doses of NVX-CoV2373, with the number of additional doses contingent on the Company’s timely achievement of supportive recommendations from the Joint Committee on Vaccination and Immunisation (the “JCVI”) (see Note 15).
The Company has an APA with the European Commission (“EC”) acting on behalf of various European Union member states to supply a minimum of 20 million and up to 100 million initial doses of NVX-CoV2373, with the option for the EC to purchase an additional 100 million doses up to a maximum aggregate of 200 million doses in one or more tranches, through 2023. The Company is in the process of finalizing a revised delivery schedule for the remaining 42 million doses of the 70 million previously committed doses under the APA that were originally scheduled for delivery during the first and second quarters of 2022. In July and August 2022, the Company was notified by the EC that it was cancelling 5 million doses of its prior commitment originally scheduled for delivery in the first and second quarters of 2022, in accordance with the APA, and reducing the order to 65 million doses (see Note 15).

Note 4 – Collaboration, License, and Supply Agreements
Serum Institute
The Company previously granted SIIPL exclusive and non-exclusive licenses for the development, co-formulation, filling and finishing, registration, and commercialization of NVX-CoV2373. SIIPL agreed to purchase the Company’s Matrix-MTM adjuvant and the Company granted SIIPL a non-exclusive license to manufacture the antigen drug substance component of NVX-CoV2373 in SIIPL’s licensed territory solely for use in the manufacture of NVX-CoV2373. The Company and SIIPL equally split the revenue from SIIPL’s sale of NVX-CoV2373 in its licensed territory, net of agreed costs. The Company also has a supply agreement with SIIPL and Serum Life Sciences Limited (“SLS”) under which SIIPL and SLS supply the Company with NVX-CoV2373 for commercialization and sale in certain territories, as well as a contract development manufacture agreement with SLS, under which SLS manufactures and supplies finished vaccine product to the Company using antigen drug substance and Matrix-M™ adjuvant supplied by the Company.

Note 9 - Leases

During the six months ended June 30, 2022, the Company concluded that changes in facts and circumstances on its CMO and CDMO agreements that had previously been determined to represent embedded lease arrangements 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, during the six months ended June 30, 2022, the Company recognized a Right-Of-Use (“ROU”) asset and a corresponding long-term operating lease liability of $19.8 million on the remeasurement of one of its long-term supply agreements using an average incremental borrowing rate of 3.0%. 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.
During the three and six months ended June 30, 2022, the Company recognized a short-term lease expense of $5.8 million and $83.9 million, respectively, related to its embedded leases and expensed $9.4 million and $19.8 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 and six months ended June 30, 2021, the Company recognized a short-term lease expense of $86.6 million and $214.2 million, respectively, related to its embedded leases and expensed $11.4 million and $12.4 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 and six months ended June 30, 2022, the Company recognized $2.3 million and $3.4 million of interest expense, respectively, on its finance lease liabilities. During the three and six months ended June 30, 2021, the Company recognized $1.8 million and $4.0 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. 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 12 – 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 14.8 million shares of common stock under equity awards granted under the 2015 Plan, which includes an increase of 2.4 million shares approved for issuance under the 2015 Plan at the Company's 2022 annual meeting of stockholders. 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 (“SARs”), and restricted stock units (“RSUs”). In addition, under the 2015 Plan, unrestricted stock, stock units, and performance awards may be granted. Stock options and SARs 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):

Total stock-based compensation expense$38,048 $53,123 $70,981 $106,183 
As of June 30, 2022, there was approximately $212 million of total unrecognized compensation expense related to unvested stock options, SARs, RSUs, and the Company’s Employee Stock Purchase Plan, as amended (“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 June 30, 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 six months ended June 30, 2022 and 2021 was approximately $8 million and $115 million, respectively.

Employee Stock Purchase Plan
The ESPP was approved at the Company's annual meeting of stockholders in June 2013. The ESPP currently authorizes an aggregate of 1.1 million shares of common stock to be purchased, and the aggregate amount of shares will continue to increase 5% on each anniversary of its adoption up to a maximum of 1.65 million shares. 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). No ESPP option periods commenced during the three months ended June 30, 2022 and 2021. As of June 30, 2022, there were 0.7 million 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 13 – 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 June 30, 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 June 30, 2022, the Company continued to maintain a full valuation allowance against its deferred tax assets, except to the extent Net Operating Losses (“NOLs”) have been used to reduce taxable income. The Company’s remaining U.S. Federal NOLs are subject to limitation in accordance with the 2017 Tax Cuts and Jobs Act (“TCJA”), which limits allowable NOL deductions to 80% of federal taxable income. Effective January 1, 2022, a provision of the TCJA has taken effect creating a significant change to the treatment of research and experimental expenditures under Section 174 of the IRC (“Sec. 174 expenses”). Historically, businesses have had the option of deducting Sec. 174 expenses in the year incurred or capitalizing and amortizing the costs over five years. The new TCJA provision, however, eliminates this option and will require Sec. 174 expenses associated with research conducted in the U.S. to be capitalized and amortized over a five-year period. For expenses associated with research outside of the U.S., Sec. 174 expenses will be capitalized and amortized over a 15-year period.
The Company recognized federal and state income tax expense of $1.4 million and $1.9 million, in total, for the three and six months ended June 30, 2022, respectively, and did not recognize federal or state income tax expense for the three and six months ended June 30, 2021. The Company recognized income tax expense related to foreign withholding tax on royalties of $2.2 million for the six months ended June 30, 2022 and $3.5 million and $6.6 million for the three and six months ended June 30, 2021, respectively. The Company did not recognize income tax expense related to foreign withholding tax on royalties for the three months ended June 30, 2022.
Note 14Commitments and Contingencies
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. On June 9, 2022, the co-lead plaintiffs filed an opposition to the motion to dismiss and on July 11, 2022, the Company filed a reply brief. The matter is now fully briefed. The Court has not indicated whether it intends to schedule any hearing on the motion before issuing a ruling.

After the Sinnathurai Action was filed, five derivative lawsuits were filed: 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”), William Kirst, et al. v. Stanley C. Erck, et al., No. 8:22-cv-00024-TDC (the “Kirst Action”), Amy Snyder v. Stanley C. Erck, et al., No. 8:22-cv-01415-TDC (the “Snyder Action”), and Charles R. Blackburn, et al. v. Stanley C. Erck, et al., No. 1:22-cv-01417-TDC (the “Blackburn Action”). The Meyer, Yung, Snyder, and Blackburn Actions were filed in the U.S. District Court for the District of Maryland. The Kirst Action was filed in the Circuit Court for Montgomery County, Maryland, and shortly thereafter removed to the U.S. District Court for the District of Maryland by the defendants. 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.

16

On July 21, 2022, the Court issued a memorandum opinion and order remanding the Kirst Action to state court. 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. On May 10, 2022, the Court entered an order in the Consolidated Derivative Action granting the parties’ request to stay all proceedings and deadlines pending the earlier of dismissal or the filing of an answer in the Sinnathurai Action. If a related derivative action is filed and is not stayed, the Meyer and Yung plaintiffs may seek to terminate the stay. On June 10, 2022, the Snyder and Blackburn Actions were filed. The Snyder and Blackburn plaintiffs have expressed their intent to move the court to consolidate all of the derivative actions pending in Maryland federal court and to appoint lead counsel. On July 21, 2022, the Court ordered the parties in the Consolidated Derivative Action, the Snyder Action, and the Blackburn Action to meet and confer concerning consolidation, the appointment of lead counsel, and the ongoing stay of proceedings in the Consolidated Derivative Action. Should the parties fail to reach agreement on those issues, the Snyder and Blackburn plaintiffs were granted leave to file a motion for consolidation and appointment of lead counsel by August 18, 2022.

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.
Note 15Subsequent Events
In July 2022, the Company received emergency use authorization for NVX-CoV2373 from the FDA to provide a two-dose primary series in individuals 18 years of age and over.
In July 2022, the Company entered into a modification to the OWS Agreement that amended the terms of such agreement to provide for (i) an initial delivery to the U.S. government of approximately 3 million doses of NVX-CoV2373, contingent on the timing of EUA approval by the FDA, as well as the timing of label language and artwork approvals by the FDA and the recommendation of the Advisory Committee on Immunization Practices within the United States Centers for Disease Control and Prevention, and (ii) any additional manufacture and delivery to the U.S. government up to an aggregate of 100 million doses of NVX-CoV2373 contemplated by the original OWS Agreement (inclusive of the initial batch of approximately 3 million doses) dependent on U.S. government demand, FDA guidance on strain selection, agreement between the parties on the price of such doses, and available funding. The 3 million initial doses were delivered in July 2022. Additionally, in July 2022, the Company modified its existing agreement with the DoD to provide for the initial delivery of 0.2 million doses of NVX-CoV2373 after receipt of EUA approval from the FDA, with delivery of the remaining 9.8 million doses of NVX-CoV2373 contemplated by the original agreement subject to DoD demand and available funding.
In July 2022, the Company entered into the Amended and Restated UK Supply Agreement with the Authority, which amended and restated in its entirety the Original UK Supply Agreement. Under the Amended and Restated UK Supply Agreement, the Authority agreed to purchase a minimum of 1 million doses and up to an additional 15 million doses of NVX-CoV2373, with the number of additional doses contingent on the Company’s timely achievement of supportive recommendations from the JCVI. In the event that the Company is unable to achieve the JCVI supportive recommendations, it may have to repay up to $225.0 million related to the upfront payment previously received from the Authority under the Original UK Supply Agreement. Under the Amended and Restated UK Supply Agreement, the Authority also has the option to purchase up to an additional 44 million doses, in one or more tranches, through 2024.
In July 2022 and August 2022, the Company was notified by the EC that it was cancelling its prior commitment for 5 million doses originally scheduled for delivery in the first and second quarters of 2022, in accordance with the APA.
In July 2022, the Company signed an agreement with SK bioscience for the technology transfer of the Company’s proprietary COVID-19 variant antigen materials so that SK bioscience can manufacture the drug substance targeting COVID-19 variants, including the Omicron subvariants. In addition, the companies signed an agreement to manufacture and supply the Novavax COVID-19 vaccine in a prefilled syringe.

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. 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 (“CIC”), 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 for primary series, and both homologous and heterologous booster indications, 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 names (i) Nuvaxovid™ COVID-19 Vaccine (SARS-CoV-2 rS [Recombinant, adjuvanted]), (ii) Covovax™ (manufacturing and commercialization by the Serum Institute of India Pvt. Ltd. (“SIIPL”)), or (iii) Novavax’ COVID-19 Vaccine, Adjuvanted.

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 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.

21

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. In April 2022, we announced the initiation of a Phase 3 COVID-19 vaccine booster study in adolescents ages 12-17 years as part of our PREVENT-19 trial, and in May 2022, we announced our participation in University of Oxford’s Com-COV3 booster trial of COVID-19 vaccines in adolescents ages 12-15 years. Additionally, in May 2022, we announced the initiation of a Phase 3 clinical trial for use of our Omicron variant strain vaccine as a booster. We remain in close collaboration with regulatory authorities for providing additional variant data. We expect to leverage these clinical insights to advance the use and additional regulatory approvals of our COVID-19 vaccine for primary, booster, and pediatric indications globally, 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.

As of June 30, 2022, the remaining balance under our June 2021 Sales Agreement was approximately $318 million.
During the six months ended June 30, 2021, we sold 2.6 million shares of our common stock resulting in net proceeds of approximately $565 million, under our various At Market Issuance Sales agreements then in effect.
Critical Accounting Policies and Use of Estimates

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements (unaudited) and the accompanying notes, which have been prepared in accordance with generally accepted accounting principles in the United States.

23

The preparation of our consolidated financial statements requires us to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities and equity and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Our critical accounting policies and estimates are included under Item 7 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, as filed with the SEC, and are updated for inventory valuation below.
Inventory Valuation
We periodically analyze our inventories for excess amounts or obsolescence and write down obsolete or otherwise unmarketable inventory to its estimated net realizable value based on assumptions about expected future demand and market conditions. Our assumptions about expected future demand are inherently uncertain and if we were to change any of these judgments or estimates, it could cause a material increase or decrease in the amount of inventory write down that we report in a particular period. Expense incurred related to excess inventory and obsolete inventory is recorded as a component of cost of sales in the consolidated statement of operations.
Recent Accounting Pronouncements Not Yet Adopted
See “Note 2―Summary of Significant Accounting Policies” included in our Notes to Consolidated Financial Statements (under the caption “Recent Accounting Pronouncements”).
Results of Operations
The following is a discussion of the historical financial condition and results of our operations that should be read in conjunction with the unaudited consolidated financial statements and notes set forth in this Quarterly Report.

Royalties and other22,696 25,528 (2,832)
Total revenue$185,925 $298,017 $(112,092)
Revenue for the three months ended June 30, 2022 was $185.9 million as compared to $298.0 million for the same period in 2021, a decrease of $112.1 million. Revenue for the three months ended June 30, 2022 was primarily comprised of revenue for services performed under the agreement with the U.S. government partnership formerly known as OWS (“OWS Agreement”) and revenue from product sales of NVX-CoV2373. Revenue for the three months ended June 30, 2021 was primarily comprised of revenue for services performed under the OWS Agreement and our funding agreements with CEPI. The decrease in revenue was due to decreased development activities under the OWS Agreement as we began commercial sales of NVX-CoV2373, partially offset by an increase in revenue due to the commencement of product sales 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. Certain revenue from product sales of NVX-CoV2373 that was originally planned for the three months ended June 30, 2022 is now planned for the second half of 2022 based on requested and revised customer delivery plans. Revenue in 2022 is also expected to increase due to 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.

Selling, general, and administrative108,160 73,161 34,999 
Total expenses$668,885 $643,846 $25,039 

Cost of Sales
Cost of sales was $271.1 million, or 489% of product sales, for the three months ended June 30, 2022, including expense of $255.3 million related to excess, obsolete, or expired inventory and losses on firm purchase commitments. Prior to receiving regulatory approval, we expensed manufacturing costs as research and development expenses. After receiving regulatory 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 at June 30, 2022 we had approximately $0.3 billion of commercial inventory that was expensed prior to approval. We expect to utilize all of our reduced-cost inventory during 2022. If inventory sold for the three months ended June 30, 2022 was valued at expected standard cost, including expenses related to excess and obsolete inventory, adjusted cost of sales for the period would have been approximately $279.5 million, or 504% of product sales, an adjustment of $8.4 million as compared to cost of sales recognized. The cost of sales to high income countries is expected to be between 15% and 30% of product sales based on our standard cost. 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 $289.6 million for the three months ended June 30, 2022 as compared to $570.7 million for the three months ended June 30, 2021, a decrease of $281.0 million primarily due to research and development of NVX-CoV2373, as summarized in the table below (in thousands):

Total research and development expenses$289,648 $570,685 
Research and development expenses for NVX-CoV2373 for the three months ended June 30, 2022 and 2021, included a benefit of $87.2 million related to previously accelerated manufacturing costs and an expense of $20.0 million related to the acceleration of manufacturing costs, respectively, 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.
25

Selling, General, and Administrative Expenses
Selling, general, and administrative expenses increased to $108.2 million for the three months ended June 30, 2022 from $73.2 million for the same period in 2021, an increase of $35.0 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 as compared to 2021 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 $26.1 million for the three months ended June 30, 2022 as compared to $2.9 million for the same period in 2021. During the three months ended June 30, 2022 and 2021, other income (expense) included a loss of $20.1 million and $2.7 million, respectively, incurred by our foreign subsidiaries, primarily related to the impact of foreign exchange rate differences on an intercompany loan with Novavax CZ.
Income Tax Expense
During the three months ended June 30, 2022 and 2021, we recognized $1.4 million and $3.5 million, respectively, of income tax expense related to federal and state income taxes and foreign withholding tax on royalties.

Net loss for the three months ended June 30, 2022 was $510.5 million, or $6.53 per share, basic, as compared to a net loss of $352.3 million, or $4.75 per share, basic, for the same period in 2021. The change in net loss during the three months ended June 30, 2022, was primarily due to decreased revenue under the OWS Agreement and the write-down of excess, obsolete, or expired inventory and losses on firm purchase commitments, partially offset by revenue from commercial sales of NVX-CoV2373 and a decrease in research and development expense.
The increase in weighted average shares outstanding for the three months ended June 30, 2022 is primarily a result of sales of our common stock and exercises of stock-based awards in 2022 and 2021.

Revenue for the six months ended June 30, 2022 was primarily comprised of revenue from product sales of NVX-CoV2373 and, to a lesser extent, revenue for services performed under the OWS Agreement. Revenue for the six months ended June 30, 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 and, to a lesser extent, royalties under our licensing arrangements, partially offset by decreased development activities under the OWS Agreement and our funding agreements with CEPI as we began commercial sales of NVX-CoV2373.

Cost of Sales
Cost of sales was $286.3 million, or 45% of product sales, for the six months ended June 30, 2022, including expense of $255.3 million related to excess, obsolete, or expired inventory and losses on firm purchase commitments. 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 at June 30, 2022 we had approximately $0.3 billion of commercial inventory that was expensed prior to approval. We expect to utilize all of our reduced-cost inventory during 2022. If inventory sold for the six months ended June 30, 2022 was valued at expected standard cost, adjusted cost of sales for the period would have been approximately $439.5 million, or 69% of product sales, an adjustment of $153.2 million as compared to cost of sales recognized. The cost of sales to high income countries is expected to be between 15% and 30% of product sales based on our standard cost. 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 $673.1 million for the six months ended June 30, 2022 from $1.2 billion for the same period in 2021, a decrease of $490.2 million, primarily due to decreased development activities relating to NVX-CoV2373, as summarized in the table below (in thousands):

Facility expenses24,072 6,405 
Other expenses31,013 18,743 
Total research and development expenses$673,131 $1,163,356 

Research and development expenses for NVX-CoV2373 for the six months ended June 30, 2022 and 2021, included a benefit of $67.4 million related to previously accelerated manufacturing costs and an expense of $43.0 million related to the acceleration of manufacturing costs, respectively, for leases that we determined were embedded in multiple manufacturing supply agreements with CMOs and CDMOs.
Selling, General, and Administrative Expenses
Selling, general, and administrative expenses increased to $204.2 million for the six months ended June 30, 2022 from $136.4 million for the same period in 2021, an increase of $67.8 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.

We had total other expense, net of $29.3 million for the six months ended June 30, 2022 as compared to $14.0 million for the same period in 2021. In the six months ended June 30, 2022 and 2021, we also recorded interest expense of $3.4 million and $4.0 million, respectively, for finance leases. During the six months ended June 30, 2022 and 2021, other income (expense) included a loss of $21.5 million and $3.9 million, respectively, incurred by our foreign subsidiaries, primarily related to the impact of foreign exchange rate differences on an intercompany loan with Novavax CZ.
Income Tax Expense
During the six months ended June 30, 2022 and 2021, we recognized $4.1 million and $6.6 million, respectively, of income tax expense related to federal and state income taxes and foreign withholding tax on royalties.

Net loss for the six months ended June 30, 2022 was $307.1 million, or $3.97 per share, as compared to $575.0 million, or $7.82 per share, for the same period in 2021. The change in net loss during the six months ended June 30, 2022 was primarily due to the commencement of commercial sales of NVX-CoV2373, partially offset by decreased revenue under the OWS Agreement, and a decrease in research and development expense, partially offset by the write-down of excess, obsolete, or expired inventory and losses on firm purchase commitments.
The increase in weighted average shares outstanding for the six months ended June 30, 2022 is primarily a result of sales of our common stock 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 (“EC”); and various countries globally. We also have grant and license agreements. As of June 30, 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 $5 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, 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 for additional indications, delivery of doses based on customer demand, and the ability of the customer to request variant vaccine in place of the prototype NVX-CoV2373 under certain of our APAs. 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 under our supply agreements generally become non-refundable upon our achievement of certain development, regulatory, and commercial milestones. Failure to meet regulatory milestones, product volume, or delivery timing obligations under our supply agreements may require us to refund portions of upfront payments or result in reduced future payments, which could result in 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.

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 Emergency Use Listing. Although Novavax is prepared to deliver the quantities of NVX-CoV2373 doses to Gavi under the terms of our supply agreement, we were notified by Gavi of its intent to seek to revise the number and timing of doses of NVX-CoV2373 supplied by Novavax under such agreement. Furthermore, Gavi may seek partial or full recovery of the prior nonrefundable payments it has made to Novavax. Our position is that Gavi has no contractual right to recover prior nonrefundable payments. 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.

In July 2022, we entered into an Amended and Restated SARS-CoV-2 Vaccine Supply Agreement (the “Amended and Restated UK Supply Agreement”) with The Secretary of State for Business, Energy and Industrial Strategy, acting on behalf of the government of the United Kingdom of Great Britain and Northern Ireland (the “Authority”), which amended and restated in its entirety the SARS-CoV-2 Vaccine Supply Agreement originally entered into in October 2020 (the “Original UK Supply Agreement”). Pursuant to the Original UK Supply Agreement, the Authority agreed to purchase 60 million doses of NVX-CoV2373. Under the Amended and Restated UK Supply Agreement, the Authority agreed to purchase a minimum of 1 million doses and up to an additional 15 million doses of NVX-CoV2373, with the number of additional doses contingent on our timely achievement of supportive recommendations from the United Kingdom’s Joint Committee on Vaccination and Immunisation (the “JCVI”). In the event that we are unable to achieve the JCVI supportive recommendations, we may have to repay up to $225.0 million related to the upfront payment we received from the Authority under the Original UK Supply Agreement. Under the Amended and Restated UK Supply Agreement, the Authority also has the option to purchase up to an additional 44 million doses, in one or more tranches, through 2024.

We have an APA with the EC acting on behalf of various EU member states to supply a minimum of 20 million and up to 100 million initial doses of NVX-CoV2373, with the option for the Commission to purchase an additional 100 million doses up to a maximum aggregate of 200 million doses in one or more tranches, through 2023. We are in the process of finalizing a revised delivery schedule for the remaining 42 million doses of the 70 million previously committed doses under our APA with the EC that were originally scheduled for delivery during the first and second quarters of 2022. In July and August 2022, we were notified by the EC that it was cancelling 5 million doses of its prior commitment originally scheduled for delivery in the first and second quarters of 2022, in accordance with the APA, and reducing the order to 65 million doses.

In July 2022, we entered into a modification to the OWS Agreement that amended the terms of such agreement to provide for (i) an initial delivery to the U.S. government of approximately 3 million doses of NVX-CoV2373, contingent on the timing of EUA approval by the FDA, as well as the timing of label language and artwork approvals by the FDA and the recommendation of the Advisory Committee on Immunization Practices within the CDC, and (ii) any additional manufacture and delivery to the U.S. government up to an aggregate of 100 million doses of NVX-CoV2373 contemplated by the original OWS Agreement (inclusive of the initial batch of approximately 3 million doses) dependent on U.S. government demand, FDA guidance on strain selection, agreement between the parties on the price of such doses, and available funding. Additionally, in July 2022, we entered into a modification to our existing agreement with the DoD that amended the terms of such agreement to provide for the initial delivery of 0.2 million doses of NVX-CoV2373 after receipt of EUA approval from the FDA, with delivery of the remaining 9.8 million doses of NVX-CoV2373 contemplated by the original agreement subject to DoD demand and available funding.

In the six months ended June 30, 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, revenue under our OWS Agreement, our cash and cash equivalents, and other potential funding sources.
As of June 30, 2022, we had $1.4 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 six months ended June 30, 2022 and 2021 (in thousands):

Net cash used in operating activities was $259.4 million for the six months ended June 30, 2022, as compared to net cash provided by operating activities of $807.5 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 six months ended June 30, 2022 as compared to an increase in cash due to the receipt of upfront payments under APAs during the six months ended June 30, 2021.
During the six months ended June 30, 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 six months ended June 30, 2022 and 2021 were $41.4 million and $28.9 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 six months ended June 30, 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 $24 million as of June 30, 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 June 30, 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 June 30, 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.
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 June 30, 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. On June 9, 2022, the co-lead plaintiffs filed an opposition to the motion to dismiss and on July 11, 2022, the Company filed a reply brief. The matter is now fully briefed. The Court has not indicated whether it intends to schedule any hearing on the motion before issuing a ruling.

After the Sinnathurai Action was filed, five derivative lawsuits were filed: 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”), William Kirst, et al. v. Stanley C. Erck, et al., No. 8:22-cv-00024-TDC (the “Kirst Action”), Amy Snyder v. Stanley C. Erck, et al., No. 8:22-cv-01415-TDC (the “Snyder Action”), and Charles R. Blackburn, et al. v. Stanley C. Erck, et al., No. 1:22-cv-01417-TDC (the “Blackburn Action”). The Meyer, Yung, Snyder, and Blackburn Actions were filed in the U.S. District Court for the District of Maryland. The Kirst Action was filed in the Circuit Court for Montgomery County, Maryland, and shortly thereafter removed to the U.S. District Court for the District of Maryland by the defendants. 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.

32

On July 21, 2022, the Court issued a memorandum opinion and order remanding the Kirst Action to state court. 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. On May 10, 2022, the Court entered an order in the Consolidated Derivative Action granting the parties’ request to stay all proceedings and deadlines pending the earlier of dismissal or the filing of an answer in the Sinnathurai Action. If a related derivative action is filed and is not stayed, the Meyer and Yung plaintiffs may seek to terminate the stay. On June 10, 2022, the Snyder and Blackburn Actions were filed. The Snyder and Blackburn plaintiffs have expressed their intent to move the court to consolidate all of the derivative actions pending in Maryland federal court and to appoint lead counsel. On July 21, 2022, the Court ordered the parties in the Consolidated Derivative Action, the Snyder Action, and the Blackburn Action to meet and confer concerning consolidation, the appointment of lead counsel, and the ongoing stay of proceedings in the Consolidated Derivative Action. Should the parties fail to reach agreement on those issues, the Snyder and Blackburn plaintiffs were granted leave to file a motion for consolidation and appointment of lead counsel by August 18, 2022.

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.
Item 1A.    Risk Factors
Information regarding risk and uncertainties related to our business appears in Part I, Item 1A. “Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, which was filed with the SEC on March 1, 2022. There have been no material changes from the risk factors previously disclosed in the Annual Report on Form 10-K other than set forth below.
The emergence and transmissibility of variants of the SARS-CoV-2 virus may affect market acceptance or sales of NVX-CoV2373, and our strategy to develop versions of our COVID-19 vaccine to protect against certain variants may not be successful.
Our prototype COVID-19 vaccine, NVX-CoV2373, was developed based upon the genetic sequence of the SARS-CoV-2 virus that was first discovered in December 2019. As the SARS-CoV-2 virus continues to evolve, new strains of the virus, or those that are already in circulation, may prove more transmissible or cause more severe forms of COVID-19 disease than the predominant strains to date. For example, the Omicron and Delta variants have been observed to be more transmissible, or contagious, than previous variants. NVX-CoV2373 may not be as effective in protecting against these or other future variant strains, and NVX-CoV2373 may fail to achieve market acceptance or significant sales, despite gaining regulatory approval, provisional registration, conditional marketing authorization or emergency use authorization in a number of jurisdictions, including emergency use authorization the United States, as demand for variant-specific vaccines increases. We have several variant-specific vaccine candidates in development, including for Omicron subvariants, and bivalent formulations with NVX-CoV2373, and may develop others in the future. However, if these efforts are unsuccessful, we are slower to develop variant-specific vaccines than competitors, or these vaccine candidates prove less effective than competitors’ vaccines, these shortcomings may lead to reputational harm, loss of market share, and adverse financial results. Additionally, counterparties to certain of our existing APAs may request variant-specific vaccines in place of NVX-CoV2373 and, depending on when we are able to offer variant-specific vaccines, if at all, such counterparties may seek to delay, reduce or otherwise renegotiate their purchase commitments, which may adversely impact our ability to realize the full financial benefit of such APAs. In addition, we may expend significant resources adapting NVX-CoV2373 or conducting clinical trials to protect against variants of the SARS-CoV-2 virus, but a market for this adapted vaccine may not develop and demand may not align with our projections or cost expenditures.
33

Item 5.    Other Information
On July 1, 2022, Novavax, Inc. (the “Company”) entered into an Amended and Restated SARS-CoV-2 Vaccine Supply Agreement (the “Amended and Restated UK Supply Agreement”) with The Secretary of State for Business, Energy and Industrial Strategy, acting on behalf of the government of the United Kingdom of Great Britain and Northern Ireland (the “Authority”), which amended and restated in its entirety the SARS-CoV-2 Vaccine Supply Agreement, dated October 22, 2020, between the parties (the “Original UK Supply Agreement”). Under the Original UK Supply Agreement, the Authority agreed to purchase 60 million doses of the Company’s vaccine candidate for the SARS-CoV-2 virus (the “Vaccine”) and made an upfront payment to the Company.
Under the Amended and Restated UK Supply Agreement, the Authority agreed to purchase a minimum of 1 million doses and up to an additional 15 million doses of Vaccine, with the number of additional doses contingent on, and subject to reduction based on, the Company’s timely achievement of a supportive recommendation from the Joint Committee on Vaccination and Immunisation (the “JCVI”) that is approved by the UK Secretary of State for Health, with respect to use of Vaccine for (i) the general adult population as part of a SARS-CoV-2 vaccine booster campaign in the United Kingdom (“UK”) or (ii) the general adolescent population as part of a SARS-CoV-2 vaccine booster campaign in the UK or as a primary series SARS-CoV-2 vaccination, excluding where that recommendation relates only to one or more population groups comprising less than one million members in the UK. If the Authority does not purchase the additional 15 million doses of Vaccine or the number of such additional doses of Vaccine is reduced, the Company would have to repay a portion of the upfront payment previously received from the Authority. Under the Amended and Restated UK Supply Agreement, the Authority also has the option to purchase up to an additional 44 million doses, in one or more tranches, through 2024.
The foregoing description of the material terms of the Amended and Restated UK Supply Agreement does not purport to be complete and is qualified in its entirety by reference to the Amended and Restated UK Supply Agreement, which the Company intends to file with the Securities and Exchange Commission as an exhibit to the Company’s Quarterly Report on Form 10-Q for the quarter ending September 30, 2022.
