NOVAVAX, INC.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
SeptemberJune 30, 20222023
(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 COVID-19vaccines and vaccine (“NVX-CoV2373,” “Nuvaxovid™,” “Covovax™,” “Novavax COVID-19 Vaccine, Adjuvanted”); influenza vaccine candidate; COVID-19-Influenza Combination (“CIC”) vaccine candidate; and additional vaccine candidates including for Omicron subvariants and bivalent formulations with prototype vaccine (“NVX-CoV2373”), are genetically engineered nanostructures of conformationally correct recombinant proteins critical to disease pathogenesis and may elicit differentiated immune responses, which may be more efficacious than naturally occurring immunity or other vaccine approaches. NVX-CoV2373 andNovavax currently has one commercial program, for vaccines to prevent COVID (“Novavax COVID Vaccine, Adjuvanted”), which it markets in various territories where it is allowed to do so, under the Company’s otherbrand name “Nuvaxovid™”. Novavax’s prototype COVID vaccine candidates incorporate the Company's proprietary Matrix-M adjuvant to enhance the immune response and stimulate higher levels of functional antibodies and induce a cellular immune response. The Company has announced datawas derived from its ongoing PREVENT-19 study supporting the use of NVX-CoV2373 for homologous boosting in adults and adolescents aged 12 through 17. Additional findings in Phase 3 COVID-19 Omicron (study 311) trial showed utility of the prototype strain of COVID and is variously referred to here and in prior financial statements without branding as “NVX-CoV2373”. Our partners, Serum Institute of India Pvt. Ltd. (“SIIPL”) markets NVX-CoV2373 as “Covovax™.” Novavax is currently developing an updated vaccine which it refers to as a heterologous booster, inducing broad immune responses against contemporary Omicron variants.its “XBB COVID vaccine.”

As of September 30,Beginning in 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 for both adult and adolescent populations as a primary series and for both homologous and heterologous booster indications. Novavax is currently seeking similar approvals from multiple regulatory authorities globally for its XBB COVID vaccine as a single dose booster for the fall 2023 and subsequently. The Company exclusively depends on its supply agreement with SIIPL and its subsidiary, Serum Life Sciences Limited (“SLS”), for co-formulation, filling and finishing (other than in Europe) and on its service agreement with PCI Pharma Services (“PCI”) for finishing in Europe. The Company plans to rely on these arrangements to supply the XBB COVID vaccine, if authorized, during the 2023 fall vaccination campaign and subsequently (see Note 4).

The Company commenced commercial shipmentsNovavax is advancing development of NVX-CoV2373 doses underother vaccine candidates, including its influenza vaccine candidate, its COVID-Influenza Combination (“CIC”) vaccine candidate and additional vaccine candidates. Novavax COVID Vaccine, Adjuvanted and its other vaccine candidates incorporate the name “Novavax COVID-19 Vaccine, Adjuvanted”Company’s proprietary Matrix-M™ adjuvant to enhance the immune response and the brand name “Nuvaxovid™” in 2022.stimulate higher levels of functional antibodies and induce a cellular immune response.

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 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 loss included a foreign currency translation loss of $23.8$8.2 million and $1.4$6.4 million as of Septemberat June 30, 20222023 and December 31, 2021,2022, respectively. The aggregate foreign currency transaction gains and losses resulting from the conversion of the transaction currency to functional currency were a $0.2 million loss and a $16.1 million gain, and a $22.2 million and $21.0 million loss for the three months and six months ended June 30, 2023 and 2022, respectively, which are reflected in Other income (expense).
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, 2021.2022. 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.

Table
Liquidity and Going Concern
The accompanying unaudited consolidated financial statements have been prepared assuming that the Company will continue as a going concern within one year after the date that the financial statements are issued. In addition, as of ContentsJune 30, 2023, the Company had $517.9 million in cash and cash equivalents and restricted cash. Pursuant to the June 2023 Amendment to the advance purchase agreement (“APA”) between the Company and His Majesty the King in Right of Canada, as represented by the Minister of Public Works and Government Services, as successor in interest to Her Majesty the Queen in Right of Canada, as represented by the Minister of Public Works and Government Services (“Canadian government”), the Company received $174.8 million from the Canadian government in July 2023 with a second installment of $174.8 million that is contingent and payable upon the Company’s delivery of vaccine doses in the second half of 2023 (see Note 3). During the six months ended June 30, 2023, the Company incurred a net loss of $235.9 million and had net cash flows used in operating activities of $497.5 million.
In accordance with Accounting Standards Codification 205-40, Going Concern, the Company evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern within one year after the date that these unaudited consolidated financial statements are issued. While the Company’s current cash flow forecast for the one-year going concern look forward period estimates that there will be sufficient capital available to fund operations, this forecast is subject to significant uncertainty, including as it relates to revenue for the next 12 months, funding from the U.S. government, and a pending matter subject to arbitration proceedings. The Company’s revenue projections depend on its ability to successfully develop, manufacture, distribute and market an updated monovalent formulation of a vaccine candidate for COVID-19 for the fall 2023 COVID vaccine season, which is inherently uncertain and subject to a number of risks, including regulatory authorization, ability to timely deliver doses and commercial adoption and market acceptance. Further, failure to meet regulatory milestones, timely obtain supportive recommendations from governmental advisory committees, or achieve product volume or delivery timing obligations under the Company’s advance purchase agreements may require the Company to refund portions of upfront and other payments or result in reduced future payments. For example, if the Company fails to deliver XBB COVID vaccine doses to the Canadian government in the second half of 2023, the second installment payment of $174.8 million will be terminated and not be payable to the Company. Also, if the Company does not timely achieve supportive recommendations from the Joint Committee on Vaccination and Immunisation (the “JCVI”) of the government of the United Kingdom of Great Britain and Northern Ireland with respect to use of NVX-CoV2373 for (a) the general adult population as part of a SARS-CoV-2 vaccine booster campaign in the United Kingdom or (b) the general adolescent population as part of a SARS-CoV-2 vaccine booster campaign in the United Kingdom 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 United Kingdom, then the Company would be required to repay up to $112.5 million related to the upfront payment previously received from the Authority under the Original UK Supply Agreement. In February 2023, in connection with the execution of Modification 17 to the USG Agreement (as defined in Note 3), the U.S. government indicated to the Company that the award may not be extended past its current period of performance. If the USG Agreement is not amended, as the Company’s management had previously expected, then the Company may not receive all of the remaining $250.6 million in funding as of June 30, 2023. On January 24, 2023, Gavi, the Vaccine Alliance (“Gavi”) filed a demand for arbitration with the International Court of Arbitration regarding an alleged material breach by the Company of the Company’s advance purchase agreement with Gavi (the “Gavi APA”). The arbitration hearing is scheduled for July 2024, with a written decision to follow. The outcome of that arbitration is inherently uncertain, and it is possible the Company could be required to refund all or a portion of the remaining advance payments of $696.4 million as of June 30, 2023 (see Note 3 and Note 15).
Management believes that, given the significance of these uncertainties, substantial doubt exists regarding the Company’s ability to continue as a going concern through one year from the date that these financial statements are issued.
In May 2023, the Company announced a global restructuring and cost reduction plan (the “Restructuring Plan”) which includes a more focused investment in its NVX-CoV2373 program, reduction to its pipeline spending, the continued rationalization of its manufacturing network, a reduction to the Company’s global workforce, as well as the consolidation of facilities, and infrastructure. The workforce reduction plan included an approximately 25% reduction in the Company’s global workforce, comprised of an approximately 20% reduction in full-time Novavax employees and the remainder comprised of contractors and consultants. The Company has decided to progress CIC toward late-stage development and, as such, is assessing the impact on its workforce requirements. The Company expects the full annual impact of the cost savings from the Restructuring Plan to be realized in 2024 and approximately half of the annual impact to be realized in 2023 due to timing of implementing the measures, and the applicable laws, regulations, and other factors in the jurisdictions in which the Company operates. During the three months ended June 30, 2023, the Company recorded a charge of $4.6 million related to one-time employee severance and benefit costs and $10.1 million related to the consolidation of facilities and infrastructure (see Note 16).
7


The Company’s ability to fund Company operations is dependent upon revenue related to vaccine sales for its products and product candidates, if such product candidates receive marketing approval and are successfully commercialized, and in particular the 2023 fall COVID vaccination campaign, which is inherently uncertain and subject to a number of risks, including regulatory authorization, ability to timely deliver doses and commercial adoption and market acceptance, the resolution of certain matters, including whether, when, and how the dispute with Gavi is resolved, and management’s plans, which includes cost reductions associated with the Restructuring Plan. Management’s plans may also include raising additional capital through a combination of equity and debt financing, collaborations, strategic alliances, and marketing, distribution, or licensing arrangements. New financings may not be available to the Company on commercially acceptable terms, or at all. Also, any collaborations, strategic alliances, and marketing, distribution, or licensing arrangements may require the Company to give up some or all of its rights to a product or technology, which in some cases may be at less than the full potential value of such rights. In addition, the regulatory and commercial success of NVX-CoV2373 and the Company’s other vaccine candidates, including an influenza vaccine candidate, a CIC vaccine candidate, and a COVID-19 variant strain-containing monovalent formulation, remains uncertain. If the Company is unable to obtain additional capital, the Company will assess its capital resources and may be required to delay, reduce the scope of, or eliminate some or all of its operations, or further downsize its organization, any of which may have a material adverse effect on its business, financial condition, results of operations, and ability to operate as a going concern.
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 SalesConstraints

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 onconstrains 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 thefor 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 pricearrangements until it is probable that a significant reversal in cumulative revenue recognized will not occur. Specifically, if a customer arrangement includes a provision whereby the customer may request a discount, return, or refund for a previously satisfied performance obligation or otherwise could have the effect of decreasing the transaction price, revenue is constrained based on an estimate of the impact to the transaction price recognized until it is probable that a significant reversal in cumulative revenue recognized will not occur.
CostRestructuring
The Company recognizes restructuring charges when such costs are incurred. The Company's restructuring charges consist of Salesemployee severance and other termination benefits related to the reduction of its workforce, the consolidation of facilities, and infrastructure and other costs. Termination benefits are expensed on the date the Company notifies the employee, unless the employee must provide future service, in which case the benefits are expensed ratably over the future service period. Ongoing benefits are expensed when restructuring activities are probable and the benefit estimable.
CostSee Note 16 for additional information on the severance and employee benefit costs for terminated employees and impairment of sales includes cost of raw materials, production, and manufacturing overhead costs associatedassets in connection 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 that 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 (see Note 7). 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, and the services and products of third-party suppliers. Manufacturing overhead costs are applied to semi-finished and finished goods based on expected production levels. 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.Restructuring Plan.
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.

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, 20222023, using a modified retrospective approach, whichand it did not have a material impact on the Company’s consolidated financial statements.

TheAs of June 30, 2023, the aggregate amount of the transaction price allocated to performance obligations that were unsatisfied (or partially unsatisfied), excluding amounts related to sales-based royalties, the Gavi APA, and the reduction in doses related to the Amended and Restated UK Supply Agreement, was approximately $4$2 billion as of September 30, 2022.which $907.4 million was included in Deferred revenue. Failure to meet regulatory milestones, timely obtain supportive recommendations from governmental advisory committees, or achieve product volume or delivery timing obligations under the Company’s APAadvance purchase agreements may require the Company to refund portions of upfront and other payments or result in reduced future payments, which could adversely impact the Company’s ability to realize revenue from its unsatisfied performance obligations. 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 the 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 vaccine under certain of ourthe Company’s APAs.
Under the terms of the Gavi APA and a separate purchase agreement between Gavi and SIIPL, 1.1 billion doses of NVX-CoV2373 were to be made available to countries participating in the COVAX Facility. The remaining unfilled performance obligationsCompany expected to manufacture and distribute 350 million doses of NVX-CoV2373 to countries participating under the COVAX Facility. Under a separate purchase agreement with Gavi, SIIPL was expected to manufacture and deliver the balance of the 1.1 billion doses of NVX-CoV2373 for low- and middle-income countries participating in the COVAX Facility. The Company expected to deliver doses with antigen and adjuvant manufactured at facilities directly funded under the Company's funding agreement with Coalition for Epidemic Preparedness Innovations (“CEPI”), with initial doses supplied by SIIPL and SLS under a supply agreement. The Company expected to supply significant doses that Gavi would allocate to low-, middle- and high-income countries, subject to certain limitations, utilizing a tiered pricing schedule and Gavi could prioritize such doses to low- and middle- income countries, at lower prices. Additionally, the Company could provide additional doses of NVX-CoV2373, to the extent available from CEPI-funded manufacturing facilities, in the event that SIIPL could not materially deliver expected vaccine doses to the COVAX Facility. Under the agreement, the Company received an upfront payment of $350.0 million from Gavi in 2021 and an additional payment of $350 million in 2022 related to grant agreements or APAs are expectedthe Company’s achieving an emergency use license for NVX-CoV2373 by the WHO (the “Advance Payment Amount”).
On November 18, 2022, the Company delivered written notice to be fulfilled in less than 12 months.Gavi to terminate the Gavi APA on the basis of Gavi’s failure to procure the purchase of 350 million doses of NVX-CoV2373 from the Company as required by the Gavi APA. As of November 18, 2022, the Company had only received orders under the Gavi APA for approximately 2 million doses. On

December 2, 2022, Gavi issued a written notice purporting to terminate the Gavi APA based on Gavi’s contention that the Company repudiated the agreement and, therefore, materially breached the Gavi APA. Gavi also contends that, based on its purported termination of the Gavi APA, it is entitled to a refund of the Advance Payment Amount less any amounts that have been credited against the purchase price for binding orders placed by a buyer participating in the COVAX Facility. Since December 31, 2022, the remaining Gavi Advance Payment Amount, which is $696.4 million as of June 30, 2023, pending resolution of the dispute with Gavi related to a return of the remaining Advance Payment Amount, has been classified within Other current liabilities in the Company’s consolidated balance sheet. On January 24, 2023, Gavi filed a demand for arbitration with the International Court of Arbitration based on the claims described above. The Company recognized grant revenuefiled its Answer and Counterclaims on March 2, 2023. On April 5, 2023, Gavi filed its Reply to the Company’s Counterclaims. The arbitration hearing is scheduled for July 2024, with a written decision to follow. Arbitration is inherently uncertain, and while the Company believes that it is entitled to retain the remaining Advance Payment Amount received from Gavi, it is possible that it could be required to refund all or a portion of the remaining Advance Payment Amount from Gavi.

U.S.In May 2023, the Company extended a credit for certain doses delivered in 2022 that qualified for replacement under the contract with the Australian government. This credit is the result of a single lot sold to the Australian government that upon pre-planned 6-month stability testing was found to have fallen below the defined specifications and the lot therefore was removed from the market. The credit will be applied against the future sale of doses to the customer and, during the six months ended June 30, 2023, the Company recorded a reduction of $64.7 million in product sales, with a corresponding increase to Deferred revenue, non-current.
In April 2023, the Company amended its APA with the Canadian government, for the purchase of doses of NVX-CoV2373 (the “Canada APA”) to forfeit certain doses originally scheduled for delivery in 2022 for a payment of $100.4 million received in the second quarter of 2023. On June 30, 2023, the Company entered into an additional amendment (the “June 2023 Amendment”) to the Canada APA. Pursuant to the June 2023 Amendment, the parties revised the Canadian government’s previous commitment by (i) forfeiting certain doses of the NVX-CoV2373 previously scheduled for delivery, (ii) reducing the amount of doses of NVX-CoV2373 due for delivery, (iii) revising the delivery schedule for the remaining doses of NVX-CoV2373 to be delivered, and (iv) requiring use of the Biologics Manufacturing Centre (“BMC”) Inc. to produce bulk antigen for doses in 2024 and 2025. In connection with the forfeiture of doses of NVX-CoV2373, the Canadian government agreed to pay a total amount of $349.6 million to the Company in two equal installments in 2023, which total amount equals the remaining balance owed by the Canadian government with respect to such forfeited vaccine doses. The first installment was payable upon execution of the June 2023 Amendment and the second installment is contingent and payable upon the Company’s delivery of vaccine doses in the second half of 2023. The first installment of $174.8 million was received from the Canadian government in July 2023. If the Company fails to deliver COVID-19 vaccine doses to the Canadian government in the second half of 2023, the second installment payment of $174.8 million will be terminated and not be payable to the Company. The Canadian Government may terminate the Canada APA, as amended, if the Company fails to achieve regulatory approval for use of BMC for NVX-CoV2373 production on or before December 31, 2024. The June 2023 Amendment maintained the total contract value of the original Canada APA. Pursuant to the June 2023 Amendment, the Company and the Canadian government will endeavor to expand the Company’s previously agreed in-country commitment to Canada and to further partner to provide health, economic, and future pandemic preparedness benefits to Canada, which value may be provided through a number of activities, including without limitation, capital investments, the performance of activities or services, or the provision of technology or intellectual property licenses. Further, the parties will endeavor to enter into a memorandum of understanding (the “MOU”) to illustrate the Company’s ability to deliver such benefits over a 15 year period with an aggregate value of not less than 100% of the amount remaining to be paid under the June 2023 Amendment and ultimately received by the Company. The Company agreed to hold $20 million in escrow for the benefit of the Canadian

government, which amount is the sole recourse available to the Canadian government in the event of non-performance under the MOU.
Grants
The Company’s U.S. government partnershipagreement consists of an agreementa Project Agreement (the “OWS“Project Agreement”) and a Base 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”(the Base Agreement together with the Project Agreement are referred to as the “USG Agreement”). In July 2022,February 2023, in connection with the Company entered into a modificationexecution of Modification 17 to the OWSProject Agreement, that amended the terms of such agreement to provide for (i) an initial delivery to the U.S. government indicated to the Company that the award may not be extended past its current period of approximately 3performance, which is December 31, 2023. Also, Modification 17 included provisions requiring that the payment of $60.0 million of consideration associated with manufacturing work now be contingent upon meeting certain milestones, including the delivery of up to 1.5 million doses of NVX-CoV2373 and (ii) any additional manufacturedevelopment and deliveryregulatory milestones related to the U.S. government up to an aggregate of 100 million doses of NVX-CoV2373 contemplated by the original OWS Agreement (inclusivecommercial readiness, expansion of the initial batchEUA and development of approximately 3 million doses) dependent on U.S. government demand, FDA guidance on strain selection, agreement between the parties on the pricemultiple vial presentations. As of such doses, and available funding. The 3 million initial doses were delivered in July 2022. Additionally, in July 2022,June 30, 2023, the Company modified its existing agreementconstrained the total transaction price by $48.0 million for consideration associated with milestones that are not fully within the DoD and delivered 0.2Company’s control. This constraint, in addition to other contract changes included within Modification 17, resulted in an approximately $29 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 subjectcumulative reduction to DoD demand and available funding.
CEPI
The Company’s funding agreement with CEPI, under which CEPI has agreed to provide funding of up to $399.5 million to the Company to support the development of NVX-CoV2373, provides up to $257.0 million in grant funding and up to $142.5 million in forgivable no-interest term loans. These loans are only repayable if NVX-CoV2373 manufactured by the CMO network funded by CEPI is soldrevenue previously recognized under the Company’s APA with Gavi,contract for the Vaccine Alliance (“Gavi”), and such sales cover the Company’s costs of manufacturing the vaccine, not including manufacturing costs funded by CEPI. The timing of any loan repayments is currently uncertain given the timing and quantities of future orders under the Company’s APA with Gavi are unclear, as discussed below.

Advance Purchase Agreements (APAs)
Under the terms of the Company’s supply commitment with Gavi, which includes both Novavax’ APA with Gavi and 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 APA 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 continues to be prepared to deliver the quantities of NVX-CoV2373 doses to Gavi under the terms of the APA, 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 if it fails to order the 350 million doses it committed to order. To date, except for an initial order of approximately 2 million doses, 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, 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”). 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. As of September 30, 2022, the Company will be required to repay a minimum of $40.0 million related to the upfront payment, which is reflected in Other current liabilities, with the remaining balance of $185.0 million reflected in Deferred revenue. 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 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. 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. The Company is in the process of finalizing a revised delivery schedule for the remaining 23 million committed doses under the APA that were originally scheduled for delivery during the first and second quarters of 2022.

Note 1314 – 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 SeptemberJune 30, 20222023 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 SeptemberJune 30, 2022,2023, 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
18


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.
TheDuring the three months ended June 30, 2023 and 2022, the Company recognized federal, state, and stateforeign income tax benefit of $0.1 million and income tax expense of $2.4$1.4 million, and $4.3 million, in total, forrespectively.

On February 26, 2021, a NovavaxCompany stockholder named Thomas Golubinski filed a derivative complaint against members of the NovavaxCompany’s board of directors and members of senior management in the Delaware Court, of Chancery (the “Court”), captioned Thomas Golubinski v. Richard H. Douglas, et al., No. 2021-0172-JRS. The Company is deemed a nominal defendant. Golubinski challenged equity awards made in April 2020 and in June 2020 on the ground that they were “spring-loaded,” that is, made at a time when such board members or members of senior management allegedly possessed undisclosed positive material information concerning the Company. The complaint asserted claims for breach of fiduciary duty, waste, and unjust enrichment. The plaintiff sought an award of damages to the Company, an order rescinding both awards or requiring disgorgement, and an award of attorneys’ fees incurred in connection with the litigation. On May 10, 2021, the defendants moved to dismiss the complaint in its entirety. On June 17, 2021, the Company’s stockholders voted FOR ratification of the April 2020 awards and ratification of the June 2020 awards. Details of the ratification proposals are set forth in the Company’s Definitive Proxy Statement filed with the SEC on May 3, 2021. The results of the vote were disclosed in the Company’s Current Report on Form 8-K filed with the SEC on June 24, 2021. Thereafter, the plaintiff stipulated that, as a result of the outcome of the June 17, 2021 vote, the plaintiff no longer intends to pursue the lawsuit or any claim arising from the April 2020 and June 2020 awards. On August 23, 2021, the plaintiff filed a motion seeking an award of attorneys’ fees and expenses, to which the defendants filed an opposition. The motion was argued before the Court onOn October 18, 2022.

Overview

Novavax, Inc., together with our wholly-owned subsidiaries, isWe are 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 some 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 (“NVX-CoV2373,” “Nuvaxovid™Nuvaxovid™,” “Covovax™,” “Novavax COVID-19 Vaccine, Adjuvanted”), and are developing an influenza vaccine candidate, a COVID-19-Influenza Combination (“CIC”) vaccine candidate, and additional vaccine candidates, including for Omicron subvariants (NVX-CoV2515 for Omicron BA.1 specific vaccine), and bivalent formulations with prototype vaccine (“NVX-CoV2373”). NVX-CoV2373 that has received full marketing authorization (“MA”), approval, interim authorization, provisional approval, conditional marketing authorization (“CMA”), and emergency use authorization (“EUA”) from multiple regulatory authorities globally for both adult and adolescent populations as a primary series and for both homologous and heterologous booster indications. Additionally, in partnership with regulators and public health authorities, we have been developing and manufacturing at commercial scale our XBB COVID vaccine that is in line with the FDA, WHO, and EMA recommendations for the 2023 fall season. We intend to deliver our XBB COVID vaccine for the 2023 fall vaccination campaign pending authorization from regulatory authorities. We are also developing a stand-alone influenza vaccine candidate, high-dose COVID-19 vaccine candidate, and a CIC vaccine candidate. In addition to COVID-19 and seasonal influenza, our other areas of focus include respiratory syncytial virus (“RSV”)providing Matrix-M™ adjuvant for collaborations investigating the prevention of malaria, including R21/Matrix-M™ adjuvant malaria vaccine, which recently received authorization in several countries, as well as other preclinical vaccine research with our Matrix-M™ adjuvant in partnership with the Bill & Melinda Gates Medical Research Institute.
We intend to focus the organization to align our investments and malaria.

activities with our top priority of delivering our XBB COVID vaccine for the 2023 fall season. To maximize our opportunities and mitigate the significant risks and uncertainties of the COVID-19 market, we have progressed our cost restructuring measures to reduce spend, extend our cash runway, and operate efficiently to seek to best position the Company to deliver longer-term growth. We discuss these cost restructuring strategies in greater detail in Note 2 to our consolidated financial statements in this Quarterly Report.

diseases.
Recombinant Nanoparticle Vaccine Technology

Once a pathogenic threatpathogen of interest has been identified, the genetic sequence encoding thean 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/Sf-/BV”) insect cell-expression system, which enables efficient, large-scale expression of the optimized protein. The Sf9/Sf-/BV system produces proteinsprotein-based antigens that are properly folded and modified – modified—which can be critical for functional, protective immunity – as the vaccine antigen.immunity. 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-MMatrix-M™ adjuvant.

Matrix-M™ Adjuvant

Our proprietary Matrix-M™ adjuvant has beenis a key differentiator within our platform. This adjuvant has demonstratedenabled potent, well-tolerated,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, and plasma cells, andwhich promote the production of high affinity antibodies, therebyan immune 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 contributescontributing to increased vaccine supply and manufacturing capacity. These immune-boosting and dose-sparing capabilities contribute to the adjuvant’s highly unique profile.
We continue to evaluate commercial opportunities for the use of our Matrix-M™ adjuvant alongside vaccine antigens produced by other manufacturers. Matrix-M™ adjuvant is being evaluated in combination with several partner-led malaria vaccine candidates, including for R21/Matrix-M™ adjuvant, a malaria vaccine candidate created by the Jenner Institute, University of Oxford. The R21/Matrix-M™ adjuvant vaccine has been licensed to Serum Institute of India Pvt. Ltd. (“SIIPL”) for commercialization. Additionally, in May 2023, we entered into a 3-year agreement with the Bill & Melinda Gates Medical Research Institute to provide our Matrix-M™ adjuvant for use in preclinical vaccine research. Our adjuvant technology is also being used by commercial partners as a key component in veterinary vaccines against equine influenza and Strangles as well as the manufacture of black-widow anti-venom.

Clinical Pipeline

Our clinical pipeline encompasses vaccine candidates spanning multiple therapeutic areas including coronavirus, seasonal influenza, and RSV, in addition to providing Matrix-MTM adjuvant for collaborations investigating 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 during the conduct of concern,the trials, while displayingmaintaining a favorable safety profile. We are in the process of developing our XBB COVID vaccine, which is in line with the FDA, WHO, and EMA recommendations for the 2023 fall season. In October 2022,June 2023, at the U.S. Vaccines and Related Biological Products Advisory Committee's meeting we announced additionalshared nonclinical data from thedemonstrating that our XBB COVID vaccine induced functional immune responses for Omicron XBB.1.5, XBB1.16, and XBB.2.3 subvariants indicating broad responses that could be applicable to forward-drift variants. We are finalizing our COVID-19 Phase 3 PREVENT-19 trialStrain-Change interim study report and new results from a Lot Consistency Study (Study 307). New PREVENT-19additional nonclinical and manufacturing data addedsummaries to support our XBB COVID vaccine for EUA and other regulatory authorizations. This is in-line with the expectation set by the U.S. Health and Human Services letter to all COVID-19 manufacturers communicating that the FDA will take regulatory action on submissions and the Centers for Disease Control and Prevention will provide vaccination recommendations in the latter part of September 2023. Pending EUA and additional regulatory authorizations, we expect to commercialize our XBB COVID vaccine for the use of prototype Novavax vaccine for homologous boosting in adults2023 fall season providing access and adolescents aged 12 through 17. In all adults, boosted responses were long-lived and were demonstratedaccessibility to be relevant against currently circulating variants such as Omicron. The Lot Consistency trial met its primary endpoint, showing that three lots of COVID-19 vaccine induced comparable immune responses in adults aged 18 through 49, thereby demonstrating the consistency of the commercial manufacturing process. Additional findings showed utility of the prototype vaccine as a heterologous booster, inducing broad immune responses against contemporary Omicron variants.

We remain focused on expanding our NVX-CoV2373 vaccine labelprotein-based choice within the booster and adolescent market following global regulatory authorizations. In August 2022, we initiated the Phase 2b/3 Hummingbird global clinical trial. The trial will evaluate the safety, effectiveness (immunogenicity), and efficacy of two primary doses of NVX-CoV2373 given 21 days apart in younger children (aged six to 11 years), followed by a booster dose at six months after the primary vaccination series. We enrolled the sentinel cohort in the first age group (aged six to 11 years) in the United States. Based on initial supportive safety and tolerability data analyzed by an independent Safety Monitoring Committee, we have progressed to recruiting the full age cohort. Furthermore, through ongoing booster studies inmarket. Beyond COVID-19, our clinical trialspipeline includes seasonal influenza and continued developmentCIC vaccines, in addition to our Matrix-M™ adjuvant being used for collaborations investigating the prevention of our COVID-19 variant strain vaccine candidates, we continue to evaluate vaccine performance. We remain confident in the utility of our prototype vaccine against emerging variants, as we continue to respond to the evolving COVID landscape. We are currently analyzing preliminary clinical data from our ongoing Omicron BA.1 monovalent and bivalent strain change trial (study 311). Study 311 achieved its strain-change endpoint using BA.1 as the model omicron subvariant vaccine. However, the magnitude and breadth of the immune responses following boosting with the prototype vaccine reinforces our belief that a strain change may not be required for our technology. No significant benefit was observed for the bivalent formatted vaccine. When evaluating the response to the forward drifted BA.5 omicron subvariant, neither the BA.1 vaccine nor the prototype/BA.1 bivalent vaccine offered any advantage. We expect to leverage these clinical insights to advance additional regulatory approvals of our COVID-19 vaccine for primary, booster, and pediatric indications globally, amidst the ongoing and evolving COVID-19 pandemic.

Additionally, we are developing our quadrivalent nanoparticle influenza vaccine (qNIV) candidate, previously known as NanoFlu, which we previously advanced through a successful Phase 3 study announced in September 2021, demonstrating the utility for a stand-alone influenza vaccine or used in a combination vaccine. We continue to progress our CIC vaccine candidate, which combines NVX-CoV2373 and our qNIV approach. In October 2022, we announced positive results from the Phase 1/2 CIC clinical trial demonstrating the CIC vaccine’s ability to generate both antibody and polyfunctional CD4+ T-cell (lymphocytes that help coordinate the immune response) responses against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and homologous and heterologous influenza strains. We intend to continue the clinical development of CIC with a follow-up trial to begin in late 2022.

Furthermore, we remain interested in continuing the development of both our RSV Program for respiratory syncytial virus fusion (F) protein nanoparticle vaccine candidate (“RSV F Vaccine”) and Matrix-MTM adjuvant collaborations for malaria. There is an ongoing Phase 3 trial being conducted by our partner, Jenner Institute, University of Oxford, for R21, a malaria candidate which is formulated using our Matrix-M adjuvant. In September 2022, positive results from an ongoing Phase 1/2b study were published in The Lancet Infectious Diseases reporting safety, immunogenicity, and efficacy results at 12 months following administration of a booster vaccination. A booster dose of R21 formulated with our Matrix-M adjuvant at one year following the primary three-dose regimen maintained high efficacy against first and multiple episodes of clinical malaria. The booster vaccine induced antibody concentrations that is related to vaccine efficacy. The trial is ongoing to assess long-term follow-up of the participants and the value of further booster vaccinations.

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

Coronavirus Vaccine Clinical Development
We continue to evaluate vaccine effectiveness through ongoing and planned booster studies to support our planned requests for authorization to the FDA, WHO, and EMA for our XBB COVID vaccine for the upcoming 2023 fall season. We expect to leverage these studies to pursue additional regulatory authorizations of our COVID-19 vaccine for primary, re-vaccination, and pediatric indications globally.
Phase 3 Strain-Change Trial
In August 2023, we announced topline results from the Phase 3 Strain-Change Trial that achieved all three co-primary

endpoints demonstrating immunologic superiority for the Omicron BA.5 variant of a bivalent prototype and Omicron BA.5 vaccine compared to our prototype vaccine (NVX-CoV2373). The study compared our prototype vaccine (NVX-CoV2373), to a monovalent Omicron BA.5 vaccine and a bivalent vaccine (prototype and Omicron BA.5) in 750 adults who had previously received three or more doses of mRNA vaccine. This study design was developed in consultation with regulatory agencies to support the upcoming strain-change EUA request to the FDA for our XBB COVID vaccine.
The data also showed that the monovalent Omicron BA.5 vaccine performed better with higher neutralization titers and seroresponse rates than the bivalent vaccine (prototype and Omicron BA.5), supporting the use of our XBB COVID vaccine for the 2023 fall vaccination season. These results show that our protein-based vaccine can be successfully adapted to new variant strains.
Phase 2b/3 Hummingbird™ Trial
In August 2023, we announced topline results from our Phase 2b/3 Hummingbird™ trial that met its primary endpoints in children aged 6 through 11 years confirming immunologic effectiveness. This ongoing trial is evaluating the safety, effectiveness (immunogenicity), and efficacy of two doses of NVX-CoV2373, followed by a booster 6 months after the primary vaccination series. The trial includes three age de-escalation cohorts of 1,200 children each. The next cohort aged 2 through 5 years is fully enrolled, with topline results expected in the fourth quarter of 2023.
COVID-Influenza Combination and Stand-alone Influenza Program
In May 2023, we announced preliminary topline data from our Phase 2 trial for CIC, stand-alone influenza and high-dose COVID-19 vaccine candidates. All three vaccine candidates contain our Matrix-M™ adjuvant, showed preliminary robust immune responses, reassuring safety profiles, and reactogenicity that was comparable to the licensed influenza vaccine comparator arms. We intend to further explore our options to progress select candidates into late-stage development.
R21/Matrix-M™ Adjuvant Malaria Vaccine
Our partner-led malaria candidates present strong opportunities for future development. An ongoing Phase 3 clinical trial is being conducted for R21/Matrix-M™ adjuvant malaria vaccine, developed by our partner, the Jenner Institute, University of Oxford and manufactured by SIIPL, which is formulated with our Matrix-M™ adjuvant. In April 2023, the R21/Matrix-M™ adjuvant malaria vaccine received multiple authorizations including in Ghana and Nigeria as well as in July 2023 received authorization in Burkina Faso. We have an agreement with SIIPL related to its manufacture of R21/Matrix-M™ adjuvant malaria vaccine under which SIIPL purchases Matrix-M™ adjuvant, as well as pays royalties based on its vaccine sales.

Sales of Common Stock
In June 2021, we entered into an At Market Issuance Sales Agreement (the "June 2021 Sales Agreement"), which allows us to issue and sell up to $500.0 million in gross proceeds of shares of its common stock. During the three and six months ended March 31,June 30, 2023, we sold 7.9 million shares of our common stock under our June 2021 Sales Agreement resulting in net proceeds of approximately $68 million, of which $6 million was included in prepaid expenses and other current assets as of June 30, 2023 and received in cash in July 2023. As of June 30, 2023, the remaining balance available under the June 2021 Sales Agreement was approximately $249 million.
During the six months ended June 30, 2022, we sold 2.2 million of shares of our common stock resulting in net proceeds of approximately $179 million, under our most recent At Market Issuance Sales agreement entered in June 2021 (the “June 2021 Sales Agreement”), which allows us to issue and sell up to $500 million in gross proceeds of shares of our common stock. As of September 30, 2022, the remaining balance under our June 2021 Sales Agreement was approximately $318 million.Agreement.
During the nine months ended September 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.

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
28


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, 2021,2022, 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.SEC.

Revenue for the three months ended SeptemberJune 30, 20222023 was $734.6$424.4 million as compared to $178.8$185.9 million for the same period in 2021,2022, an increase of $555.7$238.5 million. Revenue for the three months ended SeptemberJune 30, 2023 and June 30, 2022 was primarily comprised of revenue from product sales of NVX-CoV2373 and services performed under our U.S. government agreement with Advanced Technology International (“USG Agreement”), the Consortium Management Firm acting on behalf of the Medical CBRN Defense Consortium in connection with the partnership formerly known as Operation Warp Speed. The increase in revenue is primarily due to an increased quantity of dose sales of NVX-CoV2373 during the three months ended June 30, 2023 as compared to the same period in 2022.

Product sales
Product sales for the three months ended June 30, 2023 were $285.2 million as compared to $55.5 million during the three months ended June 30, 2022. Our product sales related to sales of NVX-CoV2373 under our APA agreements. The geographic distribution of product sales was as follows:

Grant revenue for 2023 and 2022, comprised revenue for services performed under our USG Agreement. The increase was primarily due to increased support activities under the agreement with the U.S. government partnership formerly known as OWS (“OWS Agreement”). Revenue forUSG Agreement during the three months ended SeptemberJune 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 commercial sales of NVX-CoV2373 in 2022, partially offset by decreased development activities under our funding agreements with CEPI.2023.
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.

Cost of Sales
Cost of sales was $434.6$55.8 million or 69% of product sales, for the three months ended SeptemberJune 30, 2023, including expenses of $19.8 million related to excess, obsolete, or expired inventory and losses on certain firm purchase commitments and a credit of $17.9 million related to negotiated certain reductions to previously recognized firm purchase commitments. Cost of sales was $271.1 million for the three months ended June 30, 2022, including expense of $249.0$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 SeptemberJune 30, 20222023, we had approximately $0.1 billion$25.9 million of salable commercial inventory that was expensed prior to approval. We expect to utilize the majority of our reduced-cost inventory through 2023. If inventory sold for the three months ended SeptemberJune 30, 20222023 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 $444.0$71.7 million, or 71% of product sales, an adjustment of $9.4$15.9 million as compared to cost of sales recognized. TheIf inventory sold for the three months ended June 30, 2022 was valued at expected standard cost, adjusted cost of sales to high income countries is expected to be between 15% and 30%for the period would have been approximately $279.5 million, an adjustment of product sales based on our standard cost.$8.4 million. The cost of sales as a percentage of product sales may fluctuate in the future as a result of changes to our customer pricing mix or standard costs.

Cost of Sales
Cost of sales was $720.9$89.9 million or 57% of product sales, for the ninesix months ended SeptemberJune 30, 2023, including expense of $40.0 million related to excess, obsolete, or expired inventory and losses on certain firm purchase commitments and a credit of $18.8 million related to negotiated reductions to certain previously recognized firm purchase commitments. Cost of sales was $286.3 million for the six months ended June 30, 2022, including expense of $504.3$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 SeptemberJune 30, 20222023 we had approximately $0.1 billion$25.9 million of commercial inventory that was expensed prior to approval. We expect to utilize the majority of our reduced-cost inventory through 2023. If inventory sold for the ninesix months ended SeptemberJune 30, 2023 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 $120.8 million, an adjustment of $30.9 million as compared to cost of sales recognized. If inventory sold for the three months ended June 30, 2022 was valued at expected standard cost, adjusted cost of sales for the period would have been approximately $883.5$439.5 million, or 70% of product sales, an adjustment of $162.6 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.$153.2 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 $977.4$466.6 million for the ninesix months ended SeptemberJune 30, 20222023 from $1.6 billion$673.1 million for the same period in 2021,2022, a decrease of $594.1 million,$206.6 million. The decrease was primarily due to decreaseda reduction in overall expenditures relating to development activities relating toon coronavirus vaccines, including NVX-CoV2373 NVX-CoV2515, bivalent formulations,and XBB COVID vaccine, and CIC, as summarized in the table below (in thousands):

Research and development expenses for coronavirus vaccines for the ninesix months ended SeptemberJune 30, 2023 and 2022, decreased from $489.9 million to $279.9 million primarily as a result of a reduction in manufacturing and 2021, includedsupport costs under manufacturing supply agreements with CMO and CDMO, a reduction in clinical study costs and the commercialization of internal manufacturing capabilities, as offset by a benefit of $147.8$32.2 million and $67.4 million, respectively, related to previously accelerated manufacturing costs and an expense of $78.8 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. Pursuant to the Fujifilm Settlement Agreement (see Note 4 to our consolidated financial statements in this Quarterly Report), we are responsible for a Settlement Payment of up to $185.0 million to Fujifilm in connection with cancellation of manufacturing activity at FDBT under the CSA, of which $47.8 million, constituting the initial reservation fee under the CSA, was credited against the Settlement Payment on September 30, 2022. The Settlement Payment is less than amounts previously recognized as embedded lease expense and reflected in Research and development expense from FDBT manufacturing activity under the CSA prior to the Fujifilm Settlement Agreement and accordingly, during the three months ended September 30, 2022, we recorded a benefit of $98.3 million as Research and development expense.

Selling, General, and Administrative Expenses
Selling, general, and administrative expenses increased to $327.0$206.2 million for the ninesix months ended SeptemberJune 30, 20222023 from $214.1$204.2 million for the same period in 2021,2022, an increase of $112.9$2.1 million. The increase in selling, general, and administrative expenses is primarily due to an increaserestructuring expenses, partially offset by cost containment measures to reduce our operating spend including a decrease in professional fees and marketing costs in support of our NVX-CoV2373 program.

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 and repayments 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,contract research organization, 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 SeptemberJune 30, 2022,2023, 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, our advance purchase agreement with Gavi (the “Gavi APA”) and the reduction in doses related to the Amended and Restated UK Supply Agreement (as defined below), was approximately $4 billion.$2 billion, of which $907.4 million is included in Deferred revenue in our Consolidated balance

sheet. Failure to meet regulatory milestones, timely obtain supportive recommendations from governmental advisory committees, or achieve product volume or delivery timing obligations under our APA agreementsAPAs may require us to refund portions of upfront or other payments or result in reduced future payments, which could adversely impact our ability to realize revenue from our unsatisfied performance obligations. 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 vaccine 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.

Pursuant to the Fujifilm Settlement Agreement, we are responsible for a Settlement Payment of up to $185.0 million to Fujifilm in connection with the cancellation of manufacturing activity at FDBT under the Fujifilm CSA, of which (i) $47.8 million, constituting the initial reservation fee under the CSA, was credited against the Settlement Payment on September 30, 2022 and (ii) the remaining balance is to be paid in four equal quarterly installments of $34.3 million each. We paid the first and second installment during the three and six months ended June 30, 2023, respectively, and the remaining balance of $68.6 million is reflected in Accrued expenses (see Note 4 to our consolidated financial statements in this Quarterly Report).
During April 2023, we made a payment of $27.0 million to Par Sterile Products, LLC (“Par”) under the Settlement Agreement and Release of Claims (see Note 15 to our consolidated financial statements in this Quarterly Report).
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. Pursuant toWe currently depend exclusively on SIIPL and SLS for co-formulation and filling, and PCI for finishing NVX-CoV2373 and any delays or disruptions in these suppliers’ operations could prevent or delay the Fujifilm Settlement Agreement (see Note 4 to our consolidated financial statements in this Quarterly Report), we are responsible for a Settlement Paymentdelivery of up to $185.0 million to Fujifilm in connection with cancellation of manufacturing activity at FDBT under the CSA, of which $47.8 million, constituting the initial reservation fee under the CSA, was credited against the Settlement Payment on September 30, 2022. The Settlement Payment is less than amounts previously recognized as embedded lease expense and reflected in Research and development expense from FDBT manufacturing activity under the CSA prior to the Fujifilm Settlement Agreement and accordingly, during the three months ended September 30, 2022, we recorded a benefit of $98.3 million as Research and development expense.customer orders.

UnderWe have an APA with the termsCommonwealth of our supply commitment with Gavi, which includes both our APA andAustralia for 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 APA 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 continues to be prepared to deliver the quantities of NVX-CoV2373 doses to Gavi under the terms of the APA, we were notified by Gavi of its intent to seek to revise the number and timingpurchase of doses of NVX-CoV2373 supplied by Novavax under(the “Australia APA”). In April 2023, we amended the Australia APA to reduce the number of doses to be delivered with a commensurate increase in the per-dose price, such agreement. Furthermore, Gavi may seek partial or full recoverythat the total contract value of the prior nonrefundable payments it has madeAustralia APA is maintained with doses to Novavax. Our positionbe delivered through 2024. In May 2023, we extended a credit for certain doses delivered in 2022 to Australia that qualified for replacement under the Australia APA. This credit is the result of a single lot sold to the Australian government that Gavi has no contractual rightupon pre-planned 6-month stability testing was found to recover prior nonrefundable payments if ithave fallen below the defined specifications and the lot therefore was removed from the market. The credit will be applied against the future sale of doses to Australia. In July 2023, we amended the Australia APA to provide for replacement doses and to extend the delivery schedule through 2025.

We have an APA with His Majesty the King in Right of Canada as represented by the Minister of Public Works and Government Services, as successor in interest to Her Majesty the Queen in Right of Canada, as represented by the Minister of Public Works and Government Services (the “Canadian government”), for the purchase of doses of NVX-CoV2373 (the “Canada APA”). In April 2023, we amended the Canada APA to forfeit certain doses originally scheduled for delivery in 2022 for a payment of $100.4 million received in the second quarter of 2023. In June 2023, we entered into an additional amendment (the “June 2023 Amendment”) to the Canada APA. Pursuant to the June 2023 Amendment, the parties revised the Canadian government’s previous commitment by (i) forfeiting certain doses of the NVX-CoV2373 previously scheduled for delivery, (ii) reducing the amount of doses of NVX-CoV2373 due for delivery, (iii) revising the delivery schedule for the remaining doses of NVX-CoV2373 to be delivered, and (iv) requiring use of the Biologics Manufacturing Centre (“BMC”) Inc. to produce bulk antigen for doses in 2024 and 2025. In connection with the forfeiture of doses of NVX-CoV2373, the Canadian government agreed to pay a total payment amount of $349.6 million to the Company in two equal installments in 2023, which total amount equals the remaining balance owed by the Canadian government with respect to such forfeited vaccine doses. The first installment was payable upon execution of the June 2023 Amendment and the second installment is contingent and payable upon our delivery of vaccine doses in the second half of 2023. The first installment of $174.8 million was received from the Canadian government in July 2023. If the Company fails to orderdeliver COVID-19 vaccine doses to the 350Canadian government by the second half of 2023, the second installment of $174.8 million doses it committedwill be terminated and not be payable to order. To date, exceptthe Company. The Canadian government may terminate the Canada APA, as amended, if we fail to achieve regulatory approval for an initial orderuse of approximately 2 million doses, Novavax has not received an order from GaviBMC for NVX-CoV2373 production on or before December 31, 2024. The June 2023 Amendment maintained the total contract value of the original Canada APA.

Pursuant to the June 2023 Amendment, we and the timingCanadian government will endeavor to expand our previously agreed in-country commitment to Canada and quantitiesto partner to provide health, economic, and future pandemic preparedness benefits to Canada, which value may be provided through a number of future ordersactivities, including without limitation, capital investments, the performance of activities or services, or the provision of technology or intellectual property licenses. Further, the parties will endeavor to enter into a memorandum of understanding (the “MOU”) to illustrate our ability to deliver NVX-CoV2373such benefits over a 15 year period with an aggregate value of not less than 100% of the amount remaining to be paid under the June 2023 Amendment and ultimately received by us. We agreed to hold $20.0 million in escrow for the benefit of the Canadian government, which amount is the sole recourse available to the COVAX facility are unclear.Canadian government in the event of non-performance under the MOU.

In July 2022, we entered into an Amended and Restated SARS-CoV-2 Vaccine Supply Agreement (the(as amended on September 26, 2022, the “Amended and Restated UK Supply Agreement”) with The Secretary of State for Business, Energy and Industrial Strategy (as assigned to the UK Health Security Agency), 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 indated October 22, 2020, between the parties (the “Original UK Supply Agreement”). Pursuant toUnder the Original UK Supply Agreement, the Authority agreed to purchase 60 million doses of NVX-CoV2373.NVX-CoV2373 and made an upfront payment to us. Under the terms of 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 (the “Conditional Doses”) of NVX-CoV2373, with the number of additional dosesConditional Doses contingent on, and subject to reduction based on, our timely achievement of supportive recommendations from the United Kingdom’s Joint Committee on Vaccination and Immunisation (the “JCVI”). In that is approved by the eventUK Secretary of State for Health, with respect to use of the vaccine for (a) the general adult population as part of a SARS-CoV-2 vaccine booster campaign in the United Kingdom or (b) the general adolescent population as part of a SARS-CoV-2 vaccine booster campaign in the United Kingdom 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 United Kingdom. If the Authority does not purchase the Conditional Doses or the number of such Conditional Doses is reduced below 15 million doses of NVX-CoV2373, we are unable to achieve the JCVI supportive recommendations, we maywould have to repay up to $225.0 million related to the upfront payment wepreviously received from the Authority under the Original UK Supply Agreement. As of September 30, 2022, we will be required to repay a minimum of $40.0 million related to the upfront payment. 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 haveAs of November 30, 2022, the JCVI had not yet made a supportive recommendation with respect to NVX-CoV2373, thereby triggering, under the terms of the Amended and Restated UK Supply Agreement, (i) a reduction of the number of Conditional Doses from 15 million doses to 7.5 million doses, which reduced number of Conditional Doses are contingent on, and subject to further reduction based on, our timely achievement by November 30, 2023 of a supportive recommendation from JCVI that is approved by the UK Secretary of State for Health as described in the paragraph above, and (ii) an obligation for us to repay $112.5 million related to the upfront payment previously received from the Authority under the Original UK Supply Agreement. In April 2023, we repaid the $112.5 million related to the November 30, 2022 triggering event. If we are unable to timely achieve a supportive recommendation from the JCVI by November 30, 2023, a reduction in the number of Conditional Doses from 7.5 million doses to zero will be triggered and we may be required to repay an additional $112.5 million in 2024.

Under the terms of the Gavi APA, withwe received an upfront payment of $350.0 million from Gavi in 2021 and an additional payment of $350.0 million in 2022 related to our achieving an emergency use license for NVX-CoV2373 by the EC actingWHO (the “Advance Payment Amount”). On November 18, 2022, we delivered written notice to Gavi to terminate the Gavi APA on behalfthe basis of various EU member statesGavi’s failure to supply a minimumprocure the purchase of 20350 million and up to 100 million initial doses of NVX-CoV2373 from us as required by the Gavi APA. As of November 18, 2022, we had only received orders under the Gavi APA for approximately 2 million doses. On December 2, 2022, Gavi issued a written notice purporting to terminate the Gavi APA based on Gavi’s contention that the Company repudiated the agreement and, therefore, materially breached the Gavi APA. Gavi also contends that, based on its purported termination of the Gavi APA, it is entitled to a refund of the Advance Payment Amount less any amounts that have been credited against the purchase price for binding orders placed by a buyer participating in the COVAX Facility. Since December 31, 2022, the remaining Gavi Advance Payment Amount, which is $696.4 million as of June 30, 2023, pending resolution of the dispute with Gavi related to a return of the remaining Advance Payment Amount, has been classified within Other current liabilities in our consolidated balance sheet. On January 24, 2023, Gavi filed a demand for arbitration with the option forInternational Court of Arbitration based on the ECclaims described above. We filed our Answer and Counterclaims on March 2, 2023. On April 5, 2023, Gavi filed its Reply to purchase an additional 100 million doses up to a maximum aggregate of 200 million doses, in one or more tranches, through 2023. In July and August 2022, we were notified by the EC that it was cancelling 5 million doses of its prior commitment originallyour Counterclaims.

In February 2023, in connection with the execution of Modification 17 to the USG Agreement, the U.S. government indicated to us that the award may not be extended past its current period of performance.

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.2023 fall vaccination campaign.

InOur funding agreements currently include funding from the nineCoalition for Epidemic Preparedness Innovations (“CEPI”) in the form of one or more forgivable no interest term loans (“CEPI Forgivable Loan Funding”). Payments received under the CEPI Forgivable Loan Funding are only repayable if NVX-CoV2373 manufactured by the CMO network funded by CEPI is sold to one or more third parties (which would have previously included, but is not limited to, any sales under our Gavi APA prior to its termination), and such sales cover our costs of manufacturing such vaccine, not including manufacturing costs funded by CEPI. The timing and amount of any loan repayments is currently uncertain.
As of June 30, 2023, we had $517.9 million in cash and cash equivalents and restricted cash as compared to $1.3 billion as of December 31, 2022.
We funded our operations for the six months ended SeptemberJune 30, 2022, we2023 primarily funded our operations with cash and cash equivalents upfront payments under APAs,and 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 OWSUSG Agreement that supportssupport our NVX-CoV2373 vaccine development activities. In May 2023, we announced our plan to restructure our global footprint to reduce our planned expenditures. We anticipate our future operations to be funded primarily by revenue from product sales, royalties under licensing arrangements with our strategic partners, revenue under our OWSUSG Agreement, our cash and cash equivalents, and other potential funding sources.
We may from time to time seek to retire or purchase, directly or indirectly, our outstanding debt through cash purchases and/or exchanges for equity or debt, in open market purchases, privately negotiated transactions, or otherwise. Such purchases and/or exchanges, if any, will be on such terms and at such prices as we may determine, and will depend on prevailing market conditions, our liquidity requirements, contractual restrictions, and other factors. The amounts involved may be material, which could impact our capital structure, the market for our debt securities, and the price of the indebtedness being purchased and/or exchanged, and affect our liquidity.
As of September 30, 2022, we had $1.3 billion in cash and cash equivalents and restricted cash as compared to $1.5 billion as of December 31, 2021.

Net cash used in operating activities was $298.1$497.5 million for the ninesix months ended SeptemberJune 30, 2022,2023, as compared to $259.4 million for the same period in 2022. The increase in cash used in operating activities is primarily due to a decrease in upfront payments received under our APAs, partially offset by the timing of payments to vendors.
Net cash used in investing activities was $31.3 million for the six months ended June 30, 2023, as compared to $41.4 million for the same period in 2022. The decrease in cash used in investing activities is primarily due to lower expenditure on equipment and leasehold improvements.
Net cash used in financing activities was $293.0 million for the six months ended June 30, 2023, as compared to net cash provided by operatingfinance activities of $665.4$164.5 million for the same period in 2021.2022. The decreaseincrease in cash providedused in financing activities is primarily due to the application of upfront payments under APAs resulting from sales of NVX-CoV2373 during the nine months ended September 30, 2022 as compared to an increase in cash due to the receipt of upfront payments under APAs during the nine months ended September 30, 2021.
During the nine months ended September 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 nine months ended September 30, 2022 and 2021 were $66.0$325 million and $41.1 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-outrepayment of our new corporate office facility.
Our financing activities consisted primarily3.75% Convertible notes during 2023 and net proceeds of approximately $179 million from the sales of our common stock under our June 2021 Sales Agreement during 2022.

Table
While our current cash flow forecast for the one-year going concern look forward period estimates that we have sufficient capital available to fund operations, this forecast is subject to significant uncertainty, including as it relates to revenue for the next twelve months, funding from the U.S. government, and a pending matter subject to arbitration proceedings. Our revenue projections depend on our ability to successfully develop, manufacture, distribute, or market an updated monovalent formulation of Contentsa vaccine candidate for COVID-19 for the fall 2023 COVID vaccine season, which is inherently uncertain and subject to a number of risks, including regulatory authorization, ability to timely deliver doses and commercial adoption and market acceptance. Further, failure to meet regulatory milestones, timely obtain supportive recommendations from governmental advisory committees, or achieve product volume or delivery timing obligations under the Company’s advance purchase agreements may require the Company to refund portions of upfront and other payments or result in reduced future payments. In February 2023, in connection with the execution of Modification 17 to the USG Agreement, the U.S. government indicated to us that the award may not be extended past its current period of performance, which may result in us not receiving all of the remaining $250.6 million in funding as of June 30, 2023 we had previously anticipated. On January 24, 2023, Gavi filed a demand for arbitration with the International Court of Arbitration regarding an alleged material breach by us of the Gavi APA. The outcome of that arbitration is inherently uncertain, and it is possible we could be required to refund all or a portion of the remaining Advance payment Amount of $696.4 million as of June 30, 2023. See Note 3 and Note 15 to our unaudited consolidated financial statements in Part I, Item 1, “Consolidated Financial Statements” of this Quarterly Report for additional information related to the arbitration with Gavi. Management believes that, given the significance of these uncertainties, substantial doubt exists regarding our ability to continue as a going concern through one year from the date that these financial statements are issued.

In accordance with Accounting Standards Codification 205-40, Going Concern, we evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the date that these unaudited consolidated financial statements are issued. In May 2023, we announced our Restructuring Plan which includes a more focused investment in our NVX-CoV2373 program, reduction to our pipeline spending, the continued rationalization of our manufacturing network, a reduction to our global workforce, as well as the consolidation of facilities, and infrastructure. The workforce reduction plan included an approximately 25% reduction in the Company’s global workforce, comprised of an approximately 20% reduction in full-time Novavax employees and the remainder comprised of contractors and consultants. We have decided to progress CIC toward late-stage development and, as such, we are assessing the impact on our workforce requirements and ability to meet our future needs. We incurred one time restructuring expenses of $14.7 million during the three months ended June 30, 2023. See Note 16 to our unaudited consolidated financial statements in Part I for more details on restructuring. We expect the full annual impact of the cost savings to be realized in 2024 and approximately half of the annual impact to be realized in 2023 due to timing of implementing the measures, and the applicable laws, regulations, and other factors in the jurisdictions in which we operate.

Our ability to fund our operations is dependent upon revenue related to vaccine sales for our products and product candidates, if such product candidates receive marketing approval and are successfully commercialized, and in particular the 2023 Fall vaccination campaign, which is inherently uncertain and subject to a number of risks, including regulatory authorization, ability to timely deliver doses and commercial adoption and market acceptance; the resolution of certain matters, including whether, when, and how the dispute with Gavi is resolved; and management’s plans, which include completing cost reductions associated with our global restructuring and cost reduction plan. Our plans may include raising additional capital through a combination of equity and debt financings, collaborations, strategic alliances, and marketing, distribution, or licensing arrangements. New financings may not be available to us on commercially acceptable terms, or at all. Also, any collaborations, strategic alliances, and marketing, distribution, or licensing arrangements may require us to give up some or all of our rights to a product or technology, which in some cases may be at less than the full potential value of such rights. In addition, the regulatory and commercial success of NVX-CoV2373 and our other vaccine candidates, including an influenza vaccine candidate, CIC vaccine candidate, or a COVID-19 variant strain-containing monovalent formulation, remains uncertain. If we are unable to obtain additional capital, we will assess our capital resources and may be required to delay, reduce the scope of, or eliminate some or all of our operations, or further downsize our organization, any of which may have a material adverse effect on our business, financial condition, results of operations, and ability to operate as a going concern.

Item 3.    Quantitative and Qualitative Disclosures Aboutabout 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 flowand cash equivalents, cash flows, 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
38


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 offor our foreign subsidiaries is generally 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 (deficit) of approximately $17$20 million as of SeptemberJune 30, 2022.

2023.
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 marketinterest rate 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 convertible senior unsecured 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 SeptemberJune 30, 2022.2023. 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 SeptemberJune 30, 2022,2023, 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 SeptemberJune 30, 2022,2023, 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.

On November 18, 2022, the Company delivered written notice to Gavi to terminate the Gavi APA based on Gavi’s failure to procure the purchase of 350 million doses of NVX-CoV2373 from the Company as required by the Gavi APA. As of November 18, 2022, the Company had only received orders under the Gavi APA for approximately 2 million doses. On December 2, 2022, Gavi issued a written notice purporting to terminate the Gavi APA based on Gavi’s contention that the Company repudiated the agreement and, therefore, materially breached the potential lossGavi APA. Gavi also contends that, based on its purported termination of the Gavi APA, it is not reasonably estimable.entitled to a refund of the Advance Payment Amount less any amounts that have been credited against the purchase price for binding orders placed by a buyer participating in the COVAX Facility. Since December 31, 2022, the remaining Gavi Advance Payment Amount, which is $696.4 million as of June 30, 2023, pending resolution of the dispute with Gavi related to a return of the remaining Advance Payment Amount, has been classified within Other current liabilities in the Company’s consolidated balance sheet. On January 24, 2023, Gavi filed a demand for arbitration with the International Court of Arbitration based on the claims described above. The parties are engaged in discoveryCompany filed its Answer and Counterclaims on March 2, 2023. On April 5, 2023, Gavi filed its Reply to the Company’s Counterclaims. The arbitration hearing is scheduled for July 2023. While2024, with a written decision to follow. Arbitration is inherently uncertain, and while we believe that we are entitled to retain the Company maintainsremaining Advance Payment Amount received from Gavi, it is possible that no breachwe could be required to refund all or a portion 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.

Generalremaining Advance Payment Amount from Gavi.

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, 2021,2022, which was filed with the SEC on March 1, 2022,February 28, 2023, and Part II, Item 1A. “Risk Factors” of our Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2022,March 31, 2023, which was filed with the SEC on AugustMay 9, 2022.2023. There have been no material changes from the risk factors previously disclosed in the Annual Report on Form 10-K, for the fiscal year ended December 31, 20212022 and the Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2023 other than as described below.

Risks Related to Employee Matters, Managing Growth and Information Technology

Given our current cash position and cash flow forecast, and significant uncertainties related to 2023 revenue, funding from the U.S. government, and our pending arbitration with Gavi, substantial doubt exists regarding our ability to continue as a going concern through one year from the date that the financial statements included in this Quarterly Report were issued.

Our management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the date the financial statements are issued. At June 30, 2023, we had $517.9 million in cash and cash equivalents and restricted cash. During the six months ended June 30, 2023, we incurred a net loss of $235.9 million and had net cash flows used in operating activities of $497.5 million.

While our current cash flow forecast for the one-year going concern look forward period estimates that we have sufficient capital available to fund operations, this forecast is subject to significant uncertainty, including as it relates to the following:

Revenue: The Company’s revenue projections depend on its ability to successfully develop, manufacture, distribute and market an updated monovalent formulation of a vaccine candidate for COVID-19 for the fall 2023 COVID vaccine season, which is inherently uncertain and subject to a number of risks, including regulatory authorization, ability to timely deliver doses and commercial adoption and market acceptance. Further, failure to meet regulatory milestones, timely obtain supportive recommendations from governmental advisory committees, or achieve product volume or delivery timing obligations under the Company’s advance purchase agreements may require the Company to refund portions of upfront and other payments or result in reduced future payments.

Funding from the U.S. Government:Our USG Agreement will expire by its terms in December 2023. We had anticipated that the U.S. government would extend the USG Agreement until the full $1.8 billion authorized amount had been realized. In February 2023, in connection with the execution of Modification 17 to the USG Agreement, the U.S. government indicated to us that the award may not be extended past its current period of performance. If the USG Agreement is not amended, as we had previously expected, then we may not receive all of the remaining $250.6 million in funding as of June 30, 2023 we had previously anticipated pursuant to the USG Agreement.

Pending Arbitration: On January 24, 2023, Gavi filed a demand for arbitration with the International Court of Arbitration regarding an alleged material breach by us of the Gavi APA. The outcome of that arbitration is inherently uncertain, and it is possible we could be required to refund all or a portion of the remaining advance payments of $696.4 million. See Note 3 and Note 15 to our consolidated financial statements in Part I, Item 1, “Financial Information” of this Quarterly Report on Form 10-Q for additional information related to the arbitration with Gavi.

Management believes that, given the significance of these uncertainties, substantial doubt exists regarding our ability to continue as a going concern through one year from the date that these financial statements are issued.

Our ability to fund Company operations is dependent upon revenue related to vaccine sales for our products and product candidates, if such product candidates receive marketing authorization and are successfully commercialized; the resolution of certain matters, including whether, when, and how the dispute with Gavi is resolved; and management’s plans, which include cost reductions associated with the restructuring of our global footprint. Management’s plans may also include raising additional capital through a combination of equity and debt financing, collaborations, strategic alliances, and marketing, distribution, or licensing arrangements. In May 2023, we announced a global restructuring and cost reduction plan. This plan includes a more focused investment in our COVID-19 vaccine program, reduction to our pipeline spending, the continued rationalization of our manufacturing network, a reduction to our global workforce, as well as the consolidation of facilities and infrastructure. New financings may not be available to us on commercially acceptable terms, or at all. Also, any collaborations, strategic alliances, and marketing, distribution, or licensing arrangements may require us to give up some or all of our rights to a product or technology, which in some cases may be at less than the full potential value of such rights. In addition, the regulatory and commercial success of our COVID-19 vaccine and our other vaccine candidates, including an influenza vaccine candidate, CIC vaccine candidate, or a COVID-19 variant strain-containing monovalent formulation, remains uncertain. If we are unable to obtain additional capital, we will assess our capital resources and may be required to delay, reduce the scope of, or eliminate some or all of our operations, or downsize our organization, any of which may have a material adverse effect on our business, financial condition, results of operations, and ability to operate as a going concern.

Risks Related to Regulatory and Compliance Matters

If we are unable to effectively pursue the manufacture, clinical testing, regulatory authorization, and export of our XBB COVID vaccine, or COVID vaccines against future strain changes, we may encounter delays or challenges in commercially distributing these vaccines as well as gaining market acceptance for them.

Regulatory authorities globally, including the U.S. FDA, have recommended that manufacturers update their COVID vaccines with a monovalent XBB.1.5 strain for the fall 2023 COVID vaccine season and subsequent vaccination. We continue to pursue the manufacture, clinical testing, regulatory authorization, and distribution of our XBB COVID vaccine, with a goal of making it commercially available for the fall 2023 COVID vaccine season. We intend to submit applications for authorization of the XBB COVID vaccine to several regulatory authorities. We expect that regulatory authorities will continue to monitor and assess SARS-CoV-2 evolution and recommend that manufacturers make corresponding updates to the composition of their COVID vaccines at least annually.

Inherent to this evolving approach to manufacturing new strains of COVID vaccines, including our development of our XBB COVID vaccine, we may encounter regulatory authorization, manufacturing, and distribution challenges, including export challenges. In doing so, we expect to seek alignment and acceptance by regulatory authorities that would allow us to use manufacturing and analytical testing methods employed in earlier COVID vaccine production and commercialization efforts, that support an accurate characterization profile (including purity, potency, stability and like standards) of the relevant XBB COVID vaccine. For the imminent fall 2023 COVID vaccine campaign, as well as subsequent campaigns in the future, our inability to overcome product development challenges and gaining regulatory authority alignment may adversely affect our ability to obtain licensure of our XBB COVID vaccine or future COVID vaccines at all, or in a timely manner.

Regarding future COVID vaccine development, including with our XBB COVID vaccine, we may fail to receive authorization by regulatory authorities if we are unable to generate sufficient batch analysis data to demonstrate batch-to-batch consistency at commercial scale, if the data generated from our incremental research and development program do not support continued effectiveness of the vaccine to protect individuals against the then-relevant variant of SARS-CoV-2 because the vaccine does not induce an adequate level of neutralization titers against such variant, or if the product otherwise exhibits an unacceptable safety profile, rendering the benefit/risk balance unfavorable. Moreover, the new vaccine lots may not be accepted for distribution if required batch-release testing undertaken by officially designated laboratories does not show that such vaccine is of acceptable quality.

We were unable to accomplish the timely validation of the single-dose vial presentation we had intended to use with the XBB COVID vaccine in the U.S. As a result, if we obtain EUA from the FDA for this vaccine, we expect to offer the product only in a five dose vial presentation for the fall 2023 vaccination season, which may adversely impact market acceptance, rate of product returns, or require higher price concessions in the U.S.

Because the finished product is manufactured by SIIPL in India, timely authorization is needed from the Drugs Controller General of India (“DCGI”), the drug licensing body in India, to export the XBB COVID vaccine to the respective markets where regulatory review of the product application is pending.If we are unable to receive this timely DCGI authorization, we may be unable to commercially distribute our XBB COVID vaccine in a timely manner for the fall 2023 season.

If we are unable to effectively manufacture our COVID vaccines in sufficient quantities, at sufficient yields, or are unable to obtain regulatory approvals for a manufacturing facility for our COVID vaccines, we may experience delays or an adverse impact on product development, clinical trials, regulatory approvals, and commercial distribution.

We are continuing to pursue the manufacture, distribution and clinical testing of our COVID vaccine (both our Protoype COVID vaccine and our XBB COVID vaccine) for commercialization. Completion of our clinical trials and commercialization of our COVID vaccine and our other vaccine candidates requires access to, or development of, facilities to effectively manufacture our COVID vaccine and our other vaccine candidates at sufficient yields and at commercial scale. We have limited experience manufacturing any of our vaccine candidates in the volumes necessary to support commercial sales. While we have increased our global manufacturing capacity for our COVID vaccine, our efforts to establish and maintain manufacturing capabilities may not meet expectations as to timing, scale-up, reproducibility, yields, purity, cost, potency or quality. We are highly dependent on third-party organizations to conduct a significant amount of our vaccine manufacturing activities. We do not have sufficient internal manufacturing infrastructure to support global commercialization of our COVID vaccine and we have entered into third-party agreements for the components, as well as for commercial fill-finish manufacturing, for our COVID vaccine. For the fall 2023 manufacturing campaign, the antigen component of our COVID vaccine is being manufactured at SIIPL in India, and the Matrix-M™ adjuvant component of our COVID vaccine is currently being manufactured at Novavax AB and AGC Biologics in Europe. Challenges in manufacturing either the antigen component or the adjuvant, or issues in later manufacturing stages, could compromise production of our COVID vaccine. Additionally, we currently depend exclusively on SIIPL and SLS for co-formulation, filling and finishing (other than in Europe) and PCI for finishing our COVID vaccine in Europe, and any delays or disruptions in these suppliers’ operations could prevent or delay the delivery of customer orders.

Additionally, to ensure adequate inventory supply and manage our operations, we forecast anticipated manufacturing requirements and customer demand to predict inventory needs and place orders with our third-party manufacturers based on such predictions. Our ability to accurately forecast demand for our COVID vaccine could be negatively affected by many factors, including challenges in managing our commercial strategy, unanticipated changes in general market conditions or regulatory matters, and market demand for variant-specific COVID vaccines, among others. If we underestimate our third-party manufacturing requirements, we may not be able to timely meet obligations under our customer supply agreements. Conversely, if we overestimate our third-party manufacturing requirements, we may end up with inventory levels in excess of customer demand that result in a portion of our inventory becoming obsolete or expiring, as well as inventory write-downs or write-offs, or we may need to cancel previously forecasted batches of product from our third-party manufacturers, which may result in material cancellation fees. In September 2022, for example, we entered into a Confidential Settlement Agreement and Release with FUJIFILM under which we are responsible for up to $185 million to FUJIFILM in connection with the termination of manufacturing activity. In December 2022, we agreed to approximately $95 million in fees owed to AGC Biologics in connection with the cancellation of batches in 2022. If we are unable to accurately forecast demand for our COVID vaccine and the required services from third-party manufacturers, our results of operations could be materially harmed.

Manufacturing our COVID vaccine involves a complicated process with which we have limited experience. If we and our third-party manufacturers are unable to manufacture our COVID vaccine in clinical quantities or in commercial quantities and at sufficient yields and at required specifications, then clinical trials and commercialization will be delayed, and we will need to identify and reach supply arrangements with additional third parties. Third-party manufacturers also must receive FDA or equivalent foreign regulatory body approval before they can produce clinical material or commercial product which could cause delays and alter our production schedule. Our COVID vaccines are in competition with other products for access to these third-party facilities and may be subject to delays in manufacture if third parties prioritize other products. We may not be able to enter into any necessary additional third-party manufacturing arrangements on acceptable terms, or on a timely basis. In addition, we have to enter into technical transfer agreements and share our know-how with the third-party manufacturers, which can be time-consuming and may result in delays.

Because of contractual restraints and the limited number of third-party manufacturers with the expertise, required regulatory approvals and facilities to manufacture bulk vaccines at commercial-scale, replacement of a manufacturer may be expensive and time-consuming and may cause interruptions in the production of our vaccine and negatively impact our ability to timely meet obligations under our customer supply agreements. We and our third-party manufacturers may also encounter production challenges related to:
costs, scale up, and yields;
shortages of raw materials and supplies;
44


shipment delays or other supply chain disruptions
quality control and assurance;
contamination, lot consistency, potency, and purity;
shortages of qualified personnel and other capacity constraints;
compliance with strictly enforced and evolving federal, state and foreign regulations that vary in each country where products might be sold including nationalization or other territory restrictions placed on our owned and third-party manufacturing sites;
and capital funding.

Delays or interruptions could have a material adverse effect on our business, financial condition, results of operations and cash flows.
