NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

~~June~~September 30, 2023

(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,~~by discovering, developing, and ~~commercialization of~~commercializing innovative vaccines to prevent serious infectious diseases. ~~The Company’s vaccines~~Novavax offers a differentiated vaccine platform that combines a recombinant protein approach, innovative nanoparticle technology and ~~vaccine candidates are genetically engineered nanostructures of conformationally correct recombinant proteins critical~~patented Matrix-M™ adjuvant to ~~disease pathogenesis and may elicit differentiated~~enhance the immune ~~responses, which may be more efficacious than naturally occurring immunity or other vaccine approaches.~~response. Novavax currently has one commercial program, for vaccines to prevent ~~COVID~~COVID-19, which includes Nuvaxovid prototype COVID-19 vaccine ("NVX-CoV2373,” or “prototype vaccine”) and Nuvaxovid updated COVID-19 vaccine (“NVX-CoV2601,” or “updated vaccine”) (collectively, “COVID-19 Program,” or “COVID-19 Vaccine”). Local authorities have also specified nomenclature for the prototype and updated vaccines within their labeling (“Novavax ~~COVID~~COVID-19 Vaccine, Adjuvanted”) and “Novavax COVID-19, Adjuvanted (2023-2024 Formula), ~~which it markets in various territories where it is allowed to do so, under~~respectively, for the ~~brand name “Nuvaxovid™”~~U.S.). Novavax’s prototype COVID vaccine was derived from the prototype strain of COVID and is variously referred to here and in prior financial statements without branding as “NVX-CoV2373”. Our partners,The Company’s partner, Serum Institute of India Pvt. Ltd. (“SIIPL”), markets NVX-CoV2373 as “Covovax™.” ~~Novavax is currently developing an updated vaccine which it refers to as its “XBB COVID vaccine.”~~

Beginning in 2022, the Company received approval, interim authorization, provisional approval, conditional marketing authorization, and emergency use authorization (“EUA”) from multiple regulatory authorities globally for ~~NVX-CoV2373~~its prototype vaccine 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~~indications in select territories. In October 2023, the U.S. Food and Drug Administration (“U.S. FDA”) amended the EUA for its ~~XBB COVID~~prototype vaccine ~~as a single dose booster~~to include its updated vaccine. The amended EUA authorizes use of the Company’s updated vaccine in individuals 12 years and older. In October 2023, the European Commission (“EC”) granted approval for the ~~fall 2023~~Company’s updated vaccine for active immunization to prevent COVID-19 caused by SARS-CoV-2 in individuals aged 12 and ~~subsequently.~~older. 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~~its updated vaccine ~~if authorized,~~ during the ~~2023 fall~~2023-2024 vaccination ~~campaign~~season and subsequently (see Note 4).

Novavax is advancing development of other vaccine candidates, including its influenza vaccine candidate, its ~~COVID-Influenza~~COVID19-Influenza Combination (“CIC”) vaccine candidate and additional vaccine candidates. ~~Novavax COVID Vaccine, Adjuvanted~~The Company’s COVID-19 Program and its other 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.

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),~~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 ~~$8.2~~$11.9 million and $6.4 million at ~~June~~September 30, 2023 and December 31, 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~~$12.2 million loss and a ~~$16.1~~$3.9 million gain, and a ~~$22.2~~$38.6 million loss and ~~$21.0~~$59.6 million loss for the three ~~months~~ and ~~six~~nine months ended ~~June~~September 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, 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.

Liquidity and Going Concern

The accompanying unaudited consolidated financial statements have been prepared assuming, subject to the disclosures herein, 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 ~~June~~September 30, 2023, the Company had ~~$517.9~~$666.4 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”~~government (the “Canada APA”), the Company ~~received~~expects to receive the second installment of $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~~fourth quarter of 2023 (see Note 3). During the ~~six~~nine months ended ~~June~~September 30, 2023, the Company incurred a net loss of ~~$235.9~~$366.7 million and had net cash flows used in operating activities of ~~$497.5~~$537.2 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,~~Company’s ability to execute on certain cost-cutting initiatives and a pending matter subject to arbitration proceedings. The Company’s revenue projections depend on its ability to successfully ~~develop,~~ manufacture, distribute and market anits updated ~~monovalent formulation of a~~ vaccine ~~candidate for COVID-19~~ for the ~~fall 2023 COVID vaccine~~2023-2024 vaccination season, which is inherently uncertain and subject to a number of risks, including the Company’s ability to obtain regulatory ~~authorization,~~authorizations, the incidence of COVID-19 during the 2023-2024 vaccination season, the Company’s ability to timely deliver doses and achieve commercial adoption and market ~~acceptance. Further, failure~~acceptance of its updated vaccine.

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 (“APAs”) may require the Company to refund portions of upfront and other payments or result in reduced future ~~payments.~~payments which would adversely affect the Company’s ability to continue as a going concern. For example, if the Company fails to deliver ~~XBB COVID~~its updated vaccine doses to the Canadian government in the ~~second half~~fourth quarter of 2023, the second installment payment of $174.8 million will be terminated and not be payable to the Company. In addition, the Canadian government may terminate the Canada APA if the Company fails to achieve regulatory approval for use of the Biologics Manufacturing Centre, Inc. (“BMC”) for COVID-19 Vaccine production on or before December 31, 2024. 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 (the “Authority”) with respect to use of ~~NVX-CoV2373~~its COVID-19 Program 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~~SARS-CoV-2 Vaccine 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~~dated October 22, 2020, between the Company ~~that~~and 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.Authority. 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~~APA 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~~September 30, 2023 (see Note 3 and Note ~~15)~~14).

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,~~COVID-19 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 its CIC vaccine candidate 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~~nine months ended ~~June~~September 30, 2023, the Company recorded a charge of ~~$4.6~~$4.5 million related to one-time employee severance and benefit costs and recorded an impairment charge of $10.1 million related to the consolidation of facilities and infrastructure (see Note ~~16)~~15).

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~~2023-2024 vaccination ~~campaign,~~season, which is inherently uncertain and subject to a number of risks, including the incidence of COVID-19 during the 2023-2024 vaccination season, regulatory authorization, ability to timely deliver doses and commercial adoption and market acceptance of its updated vaccine, 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, asset sales, 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, asset sales 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~~the Company’s COVID-19 Program and the Company’s other vaccine candidates, including an influenza vaccine candidate, and a CIC vaccine candidate, remains uncertain. Also, the impact of the Company’s more focused investment in its COVID-19 Program, reduction to its pipeline spending, continued rationalization of its manufacturing network, reduction to its global workforce, and ~~a COVID-19 variant strain-containing monovalent formulation, remains~~consolidation of its facilities and infrastructure remain 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 Constraints

The Company constrains the transaction price for customer arrangements 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.

Restructuring

The Company recognizes restructuring charges when such costs are incurred. The ~~Company's~~Company’s restructuring charges consist of employee 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.

See Note 1615 for additional information on the severance and employee benefit costs for terminated employees and impairment of assets in connection with the Company’s Restructuring Plan.

Recent Accounting Pronouncements

Adopted

In June 2016, the Financial Accounting Standards Board 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” 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 Company adopted ASU 2020-06 on January 1, 2023, using a modified retrospective approach, and it did not have a material impact on the Company’s consolidated financial statements.

Note 3 – Revenue

The Company's accounts receivable included ~~$334.4~~$71.1 million and $53.8 million related to amounts that were billed to

customers and ~~$60.5~~$52.6 million and $28.6 million related to amounts which had not yet been billed to customers as of ~~June~~September 30, 2023 and December 31, 2022, respectively.

(1) There was no bad debt expense recorded during the three and ~~six~~nine months ended ~~June~~September 30, 2023 or 2022. There was a $6.2 million reversal of a bad debt allowance during the ~~three~~nine months ended ~~June~~September 30, 2023 due to the collection of a previously recognized allowance for doubtful accounts. To estimate the allowance for doubtful accounts, the Company evaluates the credit risk related to its customers based on historical loss experience, economic conditions, the aging of receivables, and customer-specific risks.

(2) Deductions from Deferred revenue generally related to the recognition of revenue once performance obligations on a contract with a customer are met. During the three and nine months ended September 30, 2023, deductions included a $112.5 million reclassification of refundable upfront payments previously included in Deferred revenue to Other current liabilities. There were no such reclassifications during the three and nine months ended September 30, 2022.

As of ~~June~~September 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 SARS-CoV-2 Vaccine Supply Agreement, dated as of July 1, 2022 (as amended on September 26, 2022, the “Amended and Restated UK Supply Agreement”) between the Company and the Authority, which amended and restated the Original UK Supply Agreement, was approximately $2 billion of which ~~$907.4~~$801.0 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 advance 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.~~trials. 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~~the Company’s updated vaccine in place of the prototype ~~NVX-CoV2373~~ vaccine under certain of the 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~~the prototype vaccine were to be made available to countries participating in the COVAX Facility. The Company expected to manufacture and distribute 350 million doses of ~~NVX-CoV2373~~the prototype vaccine 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~~the prototype vaccine 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,~~prototype vaccine, 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~~$350.0 million in 2022 related to the Company’s achieving an emergency use license for ~~NVX-CoV2373~~the Company’s prototype vaccine by the ~~WHO~~World Health Organization (“WHO”) (the “Advance Payment Amount”). The Company maintains that its termination of the Advance Payment Amount was valid and denies that Gavi is entitled to a refund.

On November 18, 2022, the Company delivered written notice to Gavi to terminate the Gavi APA on the basis of Gavi’s failure to procure the purchase of 350 million doses of ~~NVX-CoV2373~~the Company’s prototype vaccine 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~~September 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 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 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.

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~~nine months ended ~~June~~September 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~~the Canada 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~~COVID-19 Vaccine previously scheduled for delivery, (ii) reducing the amount of doses of ~~NVX-CoV2373~~COVID-19 Vaccine due for delivery, (iii) revising the delivery schedule for the remaining doses of ~~NVX-CoV2373~~COVID-19 Vaccine 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,~~COVID-19 Vaccine, 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~~Vaccine doses to the Canadian government in the ~~second half~~fourth quarter of 2023, the second installment payment of $174.8 million will be terminated and not be payable to the Company. The Canadian ~~Government~~government may terminate the Canada APA, as amended, if the Company fails to achieve regulatory approval for use of BMC for ~~NVX-CoV2373~~COVID-19 Vaccine 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~~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. As of September 30, 2023, the Company is in the process of negotiating the MOU. The Company agreed to hold ~~$20~~$20.0 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 agreement consists of a Project Agreement (the “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 (the Base Agreement together with the Project Agreement ~~are referred to as~~ the “USG Agreement”). In February 2023, in connection with the execution of Modification 17 to the Project Agreement (“Modification 17”), the U.S. government indicated to the Company that the award may not be extended past its current period of performance, which is December 31, 2023. Also, Modification 17 included provisions requiring that the payment of up to $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~~its prototype vaccine and

development and regulatory milestones related to commercial readiness, expansion of the EUA and development of multiple vial presentations. As of ~~June~~September 30, 2023, the Company ~~constrained~~now expects to be entitled to the ~~total transaction price~~full $1.8 billion-funding under the USG Agreement by ~~$48.0 million for consideration associated with milestones that are not fully within~~December 31, 2023, and accordingly, the ~~Company’s control. This constraint, in addition to other contract changes included within Modification 17, resulted in an approximately $29~~Company recognized a $43.8 million cumulative ~~reduction~~increase to grant revenue ~~previously recognized~~ under the contract ~~for~~during the ~~six~~three months ended ~~June~~September 30, 2023.

Royalties and Other

Royalties and other includes royalty milestone payments, sales-based royalties, and Matrix-M™ adjuvant sales.

During the three and ~~six~~nine months ended ~~June~~September 30, 2023, the Company recognized $6.0 million revenue related to sales-based royalties, and $13.8 million and $17.0 million, respectively in revenue related to a Matrix-M™ adjuvant sales.

Note 4 – Collaboration, License, and Supply Agreements

SIIPL

The Company previously granted SIIPL exclusive and non-exclusive licenses for the development, co-formulation, filling and finishing, registration, and commercialization of ~~NVX-CoV2373,~~its prototype vaccine, its proprietary COVID-19 variant antigen candidate(s), its quadrivalent influenza vaccine candidate, and its CIC vaccine candidate. SIIPL agreed to purchase the Company's Matrix-M™ adjuvant and the Company granted SIIPL a non-exclusive license to manufacture the antigen drug substance component of ~~NVX-CoV2373~~the Company’s COVID-19 Vaccine in SIIPL’s licensed territory solely for use in the manufacture of ~~NVX-CoV2373.~~COVID-19 Vaccine. The Company and SIIPL equally split the revenue from SIIPL’s sale of ~~NVX-CoV2373~~COVID-19 Vaccine in its licensed territory, net of agreed costs. The Company also has a supply agreement with SIIPL and SLS under which SIIPL and SLS supply the Company with ~~NVX-CoV2373,~~prototype vaccine, its proprietary COVID-19 variant antigen candidate(s), its quadrivalent influenza vaccine candidate, and its CIC vaccine candidate for commercialization and sale in certain territories, as well as a contract development manufacture agreement with SLS, under which SLS manufactures and supplies finished vaccine product to the Company using antigen drug substance and Matrix-M™ adjuvant supplied by the Company. In March 2020, the Company entered into an agreement with SIIPL that granted SIIPL a non-exclusive license for the use of Matrix-M™ adjuvant supplied by the Company to develop, manufacture, and commercialize R21, a malaria candidate developed by the Jenner Institute, University of Oxford (“R21/Malaria”). Under the agreement, SIIPL purchases the Company's Matrix-M™ adjuvant ~~to manufacture R21/Malaria~~for use in development activities at cost and ~~SIIPL~~for commercial purposes at a tiered commercial supply price, and pays a royalty in the ~~single to low~~single-to low- double-digit range based on vaccine sales for a period of 15 years after the first commercial sale of ~~product~~the vaccine in each country.

Takeda Pharmaceutical Company Limited

The Company has a collaboration and license agreement with Takeda Pharmaceutical Company Limited (“Takeda”) under which the Company granted Takeda an exclusive license to develop, manufacture, and commercialize ~~NVX-CoV2373~~the Company’s COVID-19 Vaccine in Japan. Under the agreement, Takeda purchases Matrix-M™ adjuvant from the Company to manufacture doses of ~~NVX-CoV2373,~~COVID-19 Vaccine, and the Company is entitled to receive milestone and sales-based royalty payments from Takeda based on the achievement of certain development and commercial milestones, as well as a portion of net profits from the sale of ~~NVX-CoV2373.~~COVID-19 Vaccine. In September 2021, Takeda finalized an agreement with the Government of Japan’s Ministry of Health, Labour and Welfare ("MHLW") for the purchase of 150 million doses of ~~NVX-CoV2373.~~its prototype vaccine. In February 2023, MHLW ~~cancelled~~canceled the remainder of doses under its agreement with Takeda. As a result, it is uncertain whether the Company will receive future sales-based royalty payments from Takeda under the terms and conditions of their current collaboration and licensing agreement.

Bill & Melinda Gates Medical Research Institute

In May 2023, wethe Company entered into a 3-year agreement with the Bill & Melinda Gates Medical Research Institute

to provide ~~our~~the Company’s Matrix-M™ adjuvant for use in preclinical vaccine research.

SK bioscience, Co., Ltd

In February 2021, the Company entered into a Collaboration and License Agreement (“CLA”) with SK bioscience, Co., Ltd. (“SK”) to manufacture and commercialize its prototype vaccine for sale to the government of South Korea. The CLA was amended in December 2021 and July 2022 to include the sale of its prototype vaccine to Thailand and Vietnam and to supply the Company with the antigen component of prototype vaccine for use in the final drug product globally, including product to be distributed by the COVAX Facility. Under the CLA, as amended, SK agreed to pay the Company a royalty on the sale of its prototype vaccine in the low to middle double-digit range. The CLA was in addition to the Company's existing manufacturing arrangement with SK under a Development and Supply Agreement (“DSA”) entered into in August 2020. In July 2022, the Company signed an additional agreement with SK for the technology transfer of the Company’s proprietary COVID-19 variant antigen materials so that SK can manufacture the drug substance targeting COVID-19 variants, including the Omicron subvariants. The companies also signed an agreement to manufacture and supply its prototype vaccine in a prefilled syringe.

In June 2023, the Company entered into a material transfer agreement with SK for the use by SK of the Company’s Matrix-M™ adjuvant in preclinical vaccine experiments for shingles, influenza, and pan-COVID-19.

In August 2023, the Company and SK entered into a Settlement Agreement and General Release (the “Settlement Agreement”) regarding mutual release by the parties of all claims arising from or in relation to statements of work (“SOWs”) canceled by the Company under the DSA and the CLA (collectively the “Business Agreements”), and other SOWs under the Business Agreements (collectively, the “Subject SOWs”), in each case, in connection with the cessation of all drug substance and drug product manufacturing activity at SK for supply to the Company. Subject SOWs canceled by the Company under the Settlement Agreement included (i) Statement of Work No. 1 dated as of December 23, 2021 as amended to date under the CLA; (ii) Statement of Work No. 5 dated as of July 18, 2022 under the DSA; and (iii) Statement of Work No. 6 dated as of July 18, 2022, and as amended as of December 28, 2022 under the DSA.

Pursuant to the Settlement Agreement, the Company is responsible for payment of $149.8 million to SK in connection with the cancellation of manufacturing activity for the SOWs under the Business Agreements, of which (i) $130.4 million was paid in August 2023 and (ii) the remaining balance is to be paid on or before November 15, 2023. Under the Settlement Agreement, the Company and SK agreed to a wind down plan with respect to the remaining products, materials and equipment under the SOWs.

Under the Settlement Agreement, the Company and SK agreed to remove certain restrictions under the CLA that have been triggered by the launch of SK’s competing vaccine SKYCovione™ in the Republic of Korea. In addition, the Company agreed to extend the term of an exclusive license to SK under the CLA for the exploitation of antigen and vaccine products utilizing Company’s proprietary coronavirus vaccine antigens and Matrix-M adjuvant in certain territories. The Company recorded $4.0 million to Deferred revenue related to the extended licenses granted to SK under the Settlement Agreement.

In August 2023, the Company also entered into a Securities Subscription Agreement (the “Subscription Agreement”) with SK, pursuant to which the Company agreed to sell and issue to SK, in a private placement (the “Private Placement”), 6.5 million shares of the Company’s common stock, par value $0.01 per share (the “Shares”) at a price of $13.00 per share for aggregate gross proceeds to the Company of approximately $84.5 million. The closing of the Private Placement occurred on August 10, 2023. The fair value of the Company’s common stock on the date of closing, based on the quoted market price, was $46.5 million, which results in a premium paid by SK of approximately $38.0 million.

The Settlement Agreement and the Subscription Agreement were negotiated concurrently between the parties, and therefore were combined for accounting purposes and analyzed as a single arrangement. As a result, the Company recorded the $46.5 million fair value of common stock issued to SK, based on the quoted market price on the date of close, as an equity transaction. The remaining elements of the arrangement were deemed to relate to the settlement of the Company’s outstanding liabilities due to SK. These elements consist primarily of the cash payable to SK of $149.8 million, offset by the premium paid on the common stock purchase by SK of $38.0 million, which resulted in a net gain upon derecognition of the liabilities due to SK of $79.2 million in connection with the settlement. As a result, during the three and nine months ended September 30, 2023, the Company recorded this net gain of $79.2 million between research and development expense, for $57.7 million, and cost of sales, for $21.5 million, proportionally based on the where the underlying costs were originally recorded.

Other Supply Agreements

Pursuant to the Fujifilm Settlement Agreement, the Company ~~is responsible for payment of~~agreed to pay up to $185.0 million (the “Settlement Payment”) to Fujifilm in connection with cancellation of manufacturing activity at FDBT under the 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, which began on March 31, 2023. As of ~~June~~September 30, 2023, the remaining payment of $68.6 million was reflected in Accrued expenses. Under the Fujifilm Settlement Agreement, the final two quarterly installments due to Fujifilm ~~is required~~were subject to Fujifilm’s obligation to use commercially reasonable efforts to mitigate ~~the~~ losses associated with the vacant manufacturing capacity caused by the termination of manufacturing activities at FDBT under the ~~Fujifilm CSA, and the final two quarterly installments will be mitigated by any~~CSA.

On October 2, 2023, the Company ~~issued~~sent a notice of breach under the Fujifilm Settlement Agreement to ~~SK bioscience Co., Ltd. (“SK bioscience)~~Fujifilm setting forth the Company’s position that Fujifilm had not used commercially reasonable efforts to ~~cancel and wind down all drug substance and drug product manufacturing activities for supply by SK bioscience to the Company.~~mitigate losses. The Company ~~recognized $20.4~~withheld the $34.3 million ~~of research and development expense associated with a take-or-pay obligation that became~~installment payment due ~~as a result~~to Fujifilm on September 30, 2023, pending resolution of the ~~cancellation.~~issues identified in the notice of breach. On October 30, 2023, FDBT filed a demand for arbitration with Judicial Arbitration and Mediation Services (“JAMS”) seeking payment of the third quarter installment of the Settlement Payment.

The Company continues to assess its manufacturing needs and intends to modify its global manufacturing footprint consistent with its contractual obligations to supply, and anticipated demand for, ~~NVX-CoV2373,~~its COVID-19 Program, and in doing so, recognizes that significant costs may be incurred.

In January 2023, the Company established the 2023 Inducement Plan (the “2023 Inducement Plan”), which provides for the granting of share-based awards to individuals who were not previously employees, or following a bona fide period of non-employment, as an inducement material to such individuals entering into employment with the Company. The Company reserved 1.0 million shares of common stock for grants under the 2023 Inducement Plan. As of ~~June~~September 30, 2023, there were ~~0.3~~0.2 million shares available for issuance under the 2023 Inducement Plan.

The 2015 Stock Incentive Plan, as amended (“2015 Plan”), was approved at the ~~Company's~~Company’s annual meeting of stockholders in June 2015. Under the 2015 Plan, equity awards may be granted to officers, directors, employees, and consultants of and advisors to the Company and any present or future subsidiary.

As of ~~June~~September 30, 2023, there were ~~0.9~~7.1 million shares available for issuance under the 2015 Plan.

The Amended and Restated 2005 Stock Incentive Plan (“2005 Plan”) expired in February 2015 and no new awards may be made under such plan, although awards will continue to be outstanding in accordance with their terms.

Stock options and SARs generally have a maximum term of ten years and may be or were granted with an exercise price that is no less than 100% of the fair market value of the ~~Company's~~Company’s common stock at the time of grant. Grants of share-based awards are generally subject to vesting over periods ranging from one to four years.

The Company recorded stock-based compensation expense in the consolidated statements of operations as follows (in

thousands):

Employee Stock Purchase Plan

The ESPP was approved at the ~~Company's~~Company’s annual meeting of stockholders in June 2013. The ESPP currently authorized an aggregate of 1.2 million shares of common stock to be purchased, and the aggregate amount of shares will continue to increase 5% on each anniversary of its adoption up to a maximum of 1.65 million shares. The ESPP allows employees to purchase shares of common stock of the Company at each purchase date through payroll deductions of up to a maximum of 15% of their compensation, at 85% of the lesser of the market price of the shares at the time of purchase or the market price on the beginning date of an option period (or, if later, the date during the option period when the employee was first eligible to participate). As of ~~June~~September 30, 2023, there were ~~0.6~~0.5 million shares available for issuance under the ESPP.

Note 1413 – Income Taxes

The Company evaluates the available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit use of the existing deferred tax assets. A significant piece of objective evidence evaluated was the cumulative loss incurred over the three-year period ended ~~June~~September 30, 2023 and that the Company has historically generated pretax losses. Such objective evidence limits the ability to consider other subjective evidence, such as projections for future growth. On the basis of this evaluation, as of ~~June~~September 30, 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

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.

During the three months ended ~~June~~September 30, 2023, ~~and 2022,~~ the Company recognized $0.7 million of federal, state, and foreign income tax ~~benefit~~benefit. During the three months ended September 30, 2022, the Company recognized $2.4 million of ~~$0.1 million~~federal, state, and foreign income tax ~~expense of $1.4 million, respectively.~~expense. During the ~~six~~nine months ended ~~June~~September 30, 2023 and 2022, the Company recognized income tax expense of ~~$1.0~~$0.3 million and ~~$1.9~~$4.3 million, respectively.

Legal Matters

Stockholder Litigation

On November 12, 2021, Sothinathan Sinnathurai filed a purported securities class action in the U.S. District Court for the District of Maryland (the “Maryland Court”) against the Company and certain members of senior management, captioned Sothinathan Sinnathurai v. Novavax, Inc., et al., No. 8:21-cv-02910-TDC (the “Sinnathurai Action”). On January 26, 2022, the Maryland Court entered an order designating David Truong, Nuggehalli Balmukund Nandkumar, and Jeffrey Gabbert as co-lead plaintiffs in the Sinnathurai Action. The co-lead plaintiffs filed a consolidated amended complaint on March 11, 2022, alleging that the defendants made certain purportedly false and misleading statements concerning the Company’s ability to manufacture ~~NVX-CoV2373~~prototype vaccine on a commercial scale and to secure the ~~NVX-CoV2373’s~~prototype vaccine’s regulatory approval. The amended complaint defines the purported class as those stockholders who purchased the Company’s securities between February 24, 2021 and October 19, 2021. On April 25, 2022, the defendants filed a motion to dismiss the consolidated amended complaint. On December 12, 2022, the Maryland Court issued a ruling granting in part and denying in part defendants’ motion to dismiss. The Maryland Court dismissed all claims against two individual defendants and claims based on certain public statements challenged in the consolidated amended complaint. The Maryland Court denied the motion to dismiss as to the remaining claims and defendants, and directed the Company and other remaining defendants to answer within fourteen days. On December 27, 2022, the Company filed its answer and affirmative defenses. On March 16, 2023, the plaintiffs filed a motion for class certification and to appoint class representatives and counsel. The Company filed its opposition to the plaintiffs’ motion on September 22, 2023.

After the Sinnathurai Action was filed, eight derivative lawsuits were filed: (i) Robert E. Meyer v. Stanley C. Erck, et al., No. 8:21-cv-02996-TDC (the “Meyer Action”), (ii) Shui Shing Yung v. Stanley C. Erck, et al., No. 8:21-cv-03248-TDC (the “Yung Action”), (iii) William Kirst, et al. v. Stanley C. Erck, et al., No. C-15-CV-21-000618 (the “Kirst Action”), (iv) Amy Snyder v. Stanley C. Erck, et al., No. 8:22-cv-01415-TDC (the “Snyder Action”), (v) Charles R. Blackburn, et al. v. Stanley C. Erck, et al., No. 1:22-cv-01417-TDC (the “Blackburn Action”), (vi) Diego J. Mesa v.

Erck, et al., No. C-15-CV-23-001550 (the “Needelman Action”). The Meyer, Yung, Snyder, and Blackburn Actions were filed in the Maryland Court. The Kirst Action was filed in the Circuit Court for Montgomery County, Maryland, and shortly thereafter removed to the Maryland Court by the defendants. The Needleman Action was also filed in the Circuit Court for Montgomery County, Maryland. The Mesa and Acosta Actions were filed in the Delaware Court of Chancery (the “Delaware Court”). The derivative lawsuits name members of the Company’s board of directors and certain members of senior management as defendants. The Company is deemed a nominal defendant. The plaintiffs assert derivative claims arising out of substantially the same alleged facts and circumstances as the Sinnathurai Action. Collectively, the derivative complaints assert claims for breach of fiduciary duty, insider selling, unjust enrichment, violation of federal securities law, abuse of control, waste, and mismanagement. Plaintiffs seek declaratory and injunctive relief, as well as an award of monetary damages and attorneys’ fees.

On February 7, 2022, the Maryland Court entered an order consolidating the Meyer and Yung Actions (the “First Consolidated Derivative Action”). The plaintiffs in the First Consolidated Derivative Action filed their consolidated derivative complaint on April 25, 2022.

On October 6, 2023, the Board of Directors of the Company formed a Special Litigation Committee (“SLC”) with full and exclusive power and authority of the Board to, among other things, investigate, review, and analyze the facts and circumstances surrounding the claims asserted in the pending derivative actions, including the claims that remain following the court’s order on the motion to dismiss in the Second Consolidated Derivative Action. On November 7, 2023, the court entered an order granting the parties’ request to stay the Second Consolidated Derivative Action for up to six months from the date of entry of the order. This includes staying the deadline for the individual defendants to respond to the consolidated amended complaint.

On July 21, 2022, the Maryland Court issued a memorandum opinion and order remanding the Kirst Action to state court. On December 6, 2022, the parties to the Kirst Action filed a stipulated schedule pursuant to which the plaintiffs were expected to file an amended complaint on December 22, 2022, and either (i) the parties would file a stipulated stay of the Kirst Action or (ii) the defendants would file a motion to stay the case by January 23, 2023. The plaintiffs filed an amended complaint on December 30, 2022. On January 23, 2023, defendants filed a motion to stay the Kirst ~~Action.~~action. On February 22, 2023, the parties in the Kirst Action filed for the Court’s approval of a stipulation staying the Kirst Action pending the resolution of defendants’ motion to dismiss in the Second Consolidated Derivative Action. On March 22, 2023, the Court entered an order staying the Kirst Action pending resolution of the ~~Motion~~motion to ~~Dismiss~~dismiss in the Second Consolidated Derivative Action. The parties continue to discuss next steps in the litigation following the Maryland Court’s ruling on the motion to dismiss the Second Consolidated Derivative Action.

On August 30, 2022, the Mesa Action was filed. On October 3, 2022, the Delaware Court entered an order granting the parties’ request to stay all proceedings and deadlines in the Mesa Action pending the earlier of dismissal of the Sinnathurai Action or the filing of an answer to the operative complaint in the Sinnathurai Action.

The financial impact of this claim, as well as the claims discussed above, is not estimable.

On ~~February 26, 2021, a Company stockholder named Thomas Golubinski filed a derivative complaint against members of~~October 6, 2023, the Company’s board of directors voted unanimously to form a Special Litigation Committee (“SLC”) vested with full power and ~~members of senior management~~authority with respect to, among other things, claims in the ~~Delaware Court, captioned Thomas Golubinski v. Richard H. Douglas, et al., No. 2021-0172-JRS.~~derivative lawsuits related to certain sales of Company stock by certain Company officers, directors, or employees. 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 inSLC has retained 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 on May 3, 2021. The results of the vote were disclosed in the Company’s Current Report on Form 8-K filed 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. On October 18, 2022, the Delaware Court denied the plaintiff’s fee application in its entirety. Under a prior Delaware Court order, the case was automatically dismissed with prejudice upon denial of the plaintiff’s fee application. On November 14, 2022, Golubinski filed a Notice of Appeal in the Supreme Court of the State of Delaware. The plaintiff / appellant filed his opening appellate brief on December 30, 2022. The Company filed its responsive brief on January 30, 2023 and the appellant filed his reply brief on February 14, 2023. On June 8, 2023, the Supreme Court affirmed the Court of Chancery’s denial of the plaintiff’s fee application. The case was closed on June 26, 2023.

On March 29, 2022, Par Sterile Products, LLC (“Par”) submitted a demand for arbitration against the Company with the American Arbitration Association, alleging that the Company breached certain provisions of the Manufacturing and Services Agreement (the “Par MSA”) that the Company entered into with Par in September 2020 to provide fill-finish manufacturing services for NVX-CoV2373. On April 4, 2023 the parties entered into a Settlement Agreement and Release of Claims pursuant to which Novavax agreed to pay $27.0 million to Par, which was fully accrued for as of March 31, 2023. Novavax characterized the payment as a $15.0 million termination fee and a $12.0 million settlement payment. Because Par and its parent company, Endo International plc, are parties to Chapter 11 bankruptcy proceedings, the Settlement Agreement and Release of Claims and the payment due thereunder required, and subsequently received, approval from the bankruptcy court. The Company has made the payment required by the Settlement Agreement and Release of Claims, and the arbitration was dismissed with prejudice following a joint motion by Par and Novavax on August 1, 2023.own independent counsel.

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~~prototype vaccine 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~~September 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 filed its Answer and Counterclaims on March 2, 2023. On April 5, 2023, Gavi filed its Reply to the Company’s Counterclaims. On August 24, 2023, Gavi filed a Statement of Claim, and on September 21, 2023, the Company filed a Statement of Defense and Counterclaim. 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.

On September 30, 2022, the Company and Fujifilm entered into the Fujifilm Settlement Agreement regarding amounts due to Fujifilm in connection with the termination of manufacturing activity at FDBT under the CSA dated August 20, 2021 and the MSA by and between the Company and Fujifilm. The MSA and CSA established the general terms and conditions applicable to Fujifilm’s manufacturing and supply activities related to the Company’s prototype vaccine under the associated statements of work. Pursuant to the Fujifilm Settlement Agreement, the Company agreed to pay up to $185.0 million (the “Settlement Payment”) to Fujifilm in connection with cancellation of manufacturing activity at FDBT. Under the Fujifilm Settlement Agreement, the final two quarterly installments due to Fujifilm were subject to Fujifilm’s obligation to use commercially reasonable efforts to mitigate losses associated with the vacant manufacturing capacity caused by the termination of manufacturing activities at FDBT under the CSA. Any replacement revenue achieved by Fujifilm’s mitigation efforts between July 1, 2023 and December 31, 2023 would offset the final two settlement payments owed by the Company. On October 2, 2023, the Company sent a notice of breach under the Fujifilm Settlement Agreement to Fujifilm setting forth the Company’s position that Fujifilm had not used commercially reasonable efforts to mitigate losses. The Company withheld the $34.3 million installment payment due to Fujifilm on September 30, 2023, pending resolution of the issues identified in the notice of breach (see Note 4). On October 30, 2023, FDBT filed a demand for arbitration with JAMS seeking payment of the withheld installment payment.

The Company is 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, the Company does not expect the resolution of these other legal proceedings to have a material adverse effect on its financial position, results of operations, or cash flows.

On October 2, 2023, the World Health Organization (“WHO”) announced its recommendation of the R21/Matrix-M™ malaria vaccine to prevent malaria in children following advice from its Strategic Advisory Group of Experts and Malaria Policy Advisory Group. The vaccine contains R21 antigen developed by University of Oxford, specific to the malaria parasite, and Novavax’s Matrix-M™ adjuvant. This recommendation is a required step on the pathway to the WHO’s prequalification (“PQ”) of the vaccine. PQ designation is necessary for United Nations agencies and partners, for example UNICEF and Gavi, to procure the vaccine for eligible countries. This is the first recommendation from WHO to support the use of a vaccine containing the Company’s Matrix-M™ adjuvant in children as young as five months of age and it is based on the results from the Phase 3 clinical trial. The R21/Matrix-M™ malaria vaccine is being developed and manufactured by SIIPL.

On October 3, 2023, the Company announced that the updated vaccine has received EUA from the U.S. FDA for active immunization to prevent COVID-19 in individuals aged 12 and older.

Overview

We 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 nanostructures of conformationally correct recombinant proteins that mimic those found on ~~natural~~ pathogens. This technology enables the immune system to recognize target proteins and develop protective ~~antibodies.~~immune responses. 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, stimulate higher levels of functional antibodies, and induce a cellular immune response.

We have developed aan updated COVID-19 vaccine ~~NVX-CoV2373~~for the 2023-2024 vaccination season. In October 2023, the U.S. FDA granted emergency use authorization (“~~Nuvaxovid™,” “Covovax™,” “Novavax~~EUA”) for our updated vaccine for active immunization to prevent COVID-19. The updated vaccine is authorized as (1) a single dose in individuals 12 years and older who have been vaccinated with any COVID-19 ~~Vaccine, Adjuvanted”~~vaccine at least 2 months after receipt of the last previous dose of COVID-19 vaccine, and (2) a series of 2 doses administered 3 weeks apart to individuals 12 years and older who were not previously vaccinated with any COVID-19 vaccine. Our updated vaccine is available within the U.S. at many major pharmacy retailers. Outside the U.S., in October 2023, we were granted approval by the European Commission (“EC”) ~~that~~for our updated vaccine. We are committed to meeting the full supply of our key target markets through their advanced purchase agreements (“APAs”). We continue to work closely with regulatory authorities for authorization of our updated vaccine globally. We previously developed a prototype COVID-19 vaccine, which has received full marketing authorization (“MA”), marketing approval, interim authorization, provisional approval, conditional marketing authorization (“CMA”), ~~and emergency use authorization (“EUA”)~~ from multiple regulatory authorities ~~globally~~in over 40 countries globally. We continue to seek full regulatory authorizations for ~~both adult and adolescent populations as a primary series and~~our prototype vaccine, which we believe will facilitate authorization for ~~both homologous and heterologous booster indications.~~ our updated strains in the future.

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 providing Matrix-M™ adjuvant for collaborations, ~~investigating the prevention of malaria,~~ including in 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, inincluding a partnership with the Bill & Melinda Gates Medical Research Institute.

We intend to focus the organization to align our investments and activities with our top priority of delivering our ~~XBB COVID~~updated vaccine for the ~~2023 fall~~2023-2024 vaccination 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.

Technology Overview

We believe our recombinant nanoparticle vaccine technology, together with our proprietary Matrix-M™ adjuvant, is well suited for the development and commercialization of vaccine candidates targeting a broad scope of respiratory and other

endemic and emerging infectious diseases.

Recombinant Nanoparticle Vaccine Technology

Once a ~~pathogen~~target of interest has been identified, the genetic sequence encoding an antigen is selected for 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 (“Sf-/BV”) insect cell-expression system, which enables efficient, large-scale expression of the optimized protein. The Sf-/BV system produces protein-based antigens that are properly folded and modified—which can be critical for functional, protective 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-M™ adjuvant.

Matrix-M™ Adjuvant

Our proprietary Matrix-M™ adjuvant is a key differentiator within our platform. This adjuvant has enabled potent, well tolerated, and durable efficacy by stimulating the entry of antigen presenting cells (“APCs”) into the injection site and enhancing antigen presentation in local lymph nodes. This in turn activates APCs, T-cell and B-cell populations, and plasma cells, which promote the production of high affinity antibodies, an immune boosting response. This potent mechanism of action enables a lower dose of antigen to achieve the desired immune response, thereby contributing 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”)~~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. In June 2023, we signed a material transfer agreement with SK bioscience Co., Ltd. (“SK”) for use of our Matrix-M™ adjuvant in preclinical vaccine experiments for shingles, influenza, and pan-COVID-19. 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.

COVID-19 Vaccine Regulatory and Licensure

In October 2023, we received EUA from the U.S. FDA for our updated vaccine, to prevent COVID-19 in individuals aged 12 and older. Our updated vaccine is marketed in the U.S. under the brand name Novavax COVID-19 Vaccine, Adjuvanted (2023-2024 Formula). In September 2023, the U.S. Centers for Disease Control and Prevention (“CDC”) Advisory Committee on Immunization Practices (“ACIP”) voted in favor of a recommendation for the use of 2023-2024 monovalent XBB containing COVID-19 vaccines authorized under EUA or approved BLA in individuals 6 months and older, which was adopted by the CDC Director. The U.S. FDA’s grant of EUA and CDC’s September 2023 recommendation makes our updated vaccine the only protein-based non-mRNA COVID-19 vaccine available in the U.S. The formulation for our updated vaccine aligns with global harmonized guidance from the U.S. FDA, EMA, and WHO recommendations for the 2023-2024 vaccination season. We continue to ~~expand the~~progress regulatory authorizations for our ~~COVID-19~~updated vaccine ~~and remain focused on~~globally. In October 2023, we were granted approval by the ~~planned EUA request~~EC for our ~~XBB COVID~~updated vaccine in individuals aged 12 and older, which followed the positive opinion for approval from the ~~2023 fall season.~~ Committee for Medicinal Products for Human Use of the EMA. We expect to meet the full supply commitment for

doses to European countries that requested it through APAs.

We have received authorizations for ~~NVX-CoV2373~~our prototype COVID-19 vaccine in over 40 countries globally including from major regulatory agencies including the ~~FDA, the~~ WHO, ~~the~~ EMA, and ~~the~~ MHRA. To date, we have received full MA, approval, interim authorization, provisional approval, CMA, and EUA for the adult population, aged 18 and older, the adolescent population, aged 12 to 17 years, and the pediatric population, aged 7 to 11 years in select territories. The regulatory authorizations for ~~NVX-CoV2373~~our prototype vaccine include primary series and both homologous and heterologous booster indications within specific countries. For the territories in which our vaccine has received regulatory authorizations, ~~NVX-CoV2373~~our prototype vaccine is marketed under the brand names (i) Nuvaxovid™ (SARS-CoV-2 rS Recombinant, adjuvanted), (ii) Covovax™ (manufacturing and commercialization by SIIPL), or (iii) Novavax COVID-19 Vaccine, Adjuvanted.

~~Below~~ In October 2023, for our prototype vaccine we ~~highlight~~received full marketing authorization in the ~~second quarter 2023 and subsequent regulatory progress made for NVX-CoV2373 through~~UK from the ~~date of this filing on Form 10-Q.~~

~~In July 2023, we initiated the rolling submission to the U.S. FDA for the Biologics License Application for the full approval of the Novavax COVID-19 Vaccine, Adjuvanted~~MHRA in individuals aged 12 ~~years~~ and ~~older.~~

~~In July 2023, the European Commission~~older, full approval in ~~the European Union granted our first~~Singapore from Singapore’s Health Sciences Authority in individuals aged 12 and older, full ~~MA for Nuvaxovid™~~registration in Australia from Australia’s Therapeutic Goods Administration as ~~primary series~~a booster in individuals aged 12 and older, and ~~as a booster~~authorization in ~~adults aged 18 and older. This decision followed~~ the ~~positive opinion in May 2023~~EU from EMA for ~~full MA from the Committee for Medicinal Products for Human Use of the European Medicines Agency.~~

~~In May 2023, the Singapore Health Sciences Authority granted extended interim authorization for Nuvaxovid™ as a non-mRNA option in adolescents aged 12 through 17 years.~~

~~Additionally in May 2023, Taiwan’s Food and Drug Administration granted EUA for Nuvaxovid™~~use as a booster in adolescents aged 12 through 17 years. We believe these authorizations for our prototype vaccine enable a pathway for additional authorizations for our updated strains of our COVID-19 vaccine in the future.

We are working to continue to expand our label for heterologous boosting in adults and adolescents, for primary and re-vaccination in younger children, and to achieve supportive policy recommendations enabling broad market access. We continue to work closely with governments, regulatory authorities, and non-governmental organizations in our commitment to facilitate global access to our COVID-19 vaccine.

Clinical Pipeline

Our clinical pipeline is comprised of vaccine candidates for infectious diseases, with our COVID-19 vaccines, our prototype vaccine ~~NVX-CoV2373,~~(NVX-CoV2373) and our updated vaccine (NVX-CoV2601), as our lead ~~product. NVX-CoV2373~~products. Our prototype has received authorizations for both adult and adolescent populations globally. We advanced ~~NVX-CoV2373,~~our prototype vaccine, 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 the trials, while maintaining a favorable safety profile. Our updated vaccine has received authorization from the U.S. FDA, and the EC. We ~~are~~advanced our updated vaccine through a Phase 3 strain-change trial and the EUA was based on non-clinical data presented 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~~ June 2023, at the U.S. Vaccines and Related Biological Products Advisory Committee's meeting we shared nonclinical data demonstrating 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 Strain-Change interim study report and additional nonclinical and manufacturing data summaries 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 2023 fall season providing access and accessibility to a protein-based choice within the market.meeting. Beyond COVID-19, our clinical pipeline includes seasonal influenza and CIC vaccines, in addition to our Matrix-M™ adjuvant being used for ~~collaborations investigating the prevention of malaria.~~collaboration in R21/Matrix-M™ adjuvant malaria vaccine.

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

Coronavirus Vaccine Clinical Development

We continue to evaluate vaccine effectiveness and safety through ongoing and planned booster studies, as well as

collect real-world evidence for our updated vaccine. While these studies were not required ahead of our EUA receipt from the U.S., they will generate data to support continued use of our ~~planned requests for authorization to the FDA, WHO, and EMA for our XBB COVID~~ vaccine ~~for the upcoming 2023 fall season.~~in subsequent seasons. 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~~and Re-vaccination Studies

Study 311 Part 2: 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~~updated vaccine ~~performed better with higher neutralization titers~~(NVX-CoV2601) 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~~demonstrated that our protein-based vaccine can be successfully adapted to new variant strains.

Study 312: In May 2023, we completed enrollment of 147 adults aged 18 and older who received 2 or 3 doses of mRNA and boosted with our prototype vaccine (NVX-CoV2373). The trial compared the prototype vaccine (NVX-CoV2373) booster on top of mRNA primed individuals compared to those primed and boosted with our prototype vaccine (NVX-CoV2373). Topline results are expected in the fourth quarter of 2023. This trial is intended to support the use of our vaccine as a second or subsequent re-vaccination.

Study 313: In September 2023, we fully enrolled 332 adults aged 18 and older in Part 1 of the study to evaluate the immunogenicity and safety of our updated vaccine (NVX-CoV2601) in previously mRNA vaccinated individuals. Part 1 topline results are expected in the fourth quarter of 2023. Part 2 of the study is in the process of enrollment and will aim to evaluate the immunogenicity of our updated vaccine (NVX-CoV2601) in previously unvaccinated adults aged 18 and older. This study is intended to support sBLA for future variant vaccine products.

Study 314: In September 2023, we fully enrolled 401 adolescents aged 12 to 17 years who were previously vaccinated with mRNA vaccines to evaluate the immunogenicity of boosting with our updated vaccine (NVX-CoV2601) and with a bivalent format vaccine containing our updated vaccine (NVX-CoV2373 + NVX-CoV2601). This data is intended to support adolescent heterologous label expansion in some territories with topline results expected in the first quarter of 2024.

Phase 2b/3 Pediatric Hummingbird™ ~~Trial~~Study

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~~demonstrating immunologic effectiveness. We remain on track to submit data for this cohort to the U.S. FDA in the first quarter of 2024. This ongoing trial is evaluating the safety, effectiveness (immunogenicity), and efficacy of two doses of ~~NVX-CoV2373,~~our prototype vaccine (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. The last cohort aged 6 to 23 months is fully enrolled and topline results are expected in first quarter of 2024.

COVID-Influenza Combination and Stand-alone Influenza Program

We continue to make strategic investments to prepare our CIC vaccine for advanced development. We have selected the CIC dose formulation and we remain on track to initiate the next study in the second half of 2024. Pending regulatory concurrence, we have designed this study to evaluate immunogenicity endpoints for accelerated approval while simultaneously expanding our safety database. We have updated the study’s designation to a Phase 3 study.

While our focus remains on the combination product, our development plans will maintain optionality to advance our stand-alone influenza vaccine, creating a pathway to potentially seek licensure. For our stand-alone influenza vaccine we have generated positive data through our previous Phase 2 trial and continue to believe this asset may be attractive from a pandemic preparedness perspective. The neutralization responses were more than double seen with Fluzone® HD for the A strains and similar performance may be expected for A/H5N1 pandemic strains.

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~~

High-dose COVID-19 Vaccine Study

Study 205: In October 2023, we initiated a Phase 2 trial to evaluate our high-dose COVID-19 vaccine for annual vaccination in older adults. The trial will compare immunogenicity levels of 5 micrograms of our prototype vaccine (NVX-CoV2373) against 5 micrograms, 35 micrograms, and 50 micrograms of our updated vaccine (NVX-CoV2601) that are matched with different levels of adjuvant. Data from this trial is intended to potentially support further ~~explore our options~~development of a higher dose formulation for older adults, similar to ~~progress select candidates into late-stage development.~~that of influenza vaccines.

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 our Matrix-M™ adjuvant ~~as well as~~for use in development activities at cost and for commercial purposes at a tiered commercial supply price, and pays ~~royalties~~a royalty in the single- to low- double digit range based on vaccine sales for a period of 15 years after the first commercial sale of the vaccine in each country.

In October 2023, the WHO announced its recommendation of R21/Matrix-M™ adjuvant malaria vaccine ~~sales.~~to prevent malaria in children following advice from its Strategic Advisory Group of Experts and Malaria Policy Advisory Group. The WHO recommended that the R21/Matrix-M™ adjuvant malaria vaccine be administered in a 4-dose schedule from five months of age. This recommendation is a required step on the pathway to the WHO’s prequalification (“PQ”) of the vaccine. PQ designation is necessary for United Nations agencies and partners, for example UNICEF and Gavi, to procure the vaccine for eligible countries. This is the first recommendation from WHO to support the use of a vaccine containing our Matrix-M™ adjuvant in children as young as five months of age and it is based on the results from the Phase 3 clinical trial.

In September 2023, results from the Phase 3 clinical trial conducted in four African countries with 4,800 children aged 36 months to five years were published in a preprint manuscript in The Lancet. The preprint manuscript reported that R21/Matrix-M™ adjuvant malaria vaccine is well-tolerated and offers high-level efficacy against clinical malaria in African children at sites of both seasonal and perennial transmission.

In July 2023, R21/Matrix-M™ adjuvant malaria vaccine received authorization in Burkina Faso and in April 2023, received authorizations in Ghana and Nigeria.

Royalties and other includes royalty milestone payments, sales-based royalties, and Matrix-M™ adjuvant sales. Royalties and other revenue during the three months ended September 30, 2023 was $19.8 million as compared to $2.2 million during the same period in 2022, an increase of $17.6 million. The increase was primarily due to increased revenue related to a Matrix-M™ adjuvant sales and sales-based royalties.

Cost of Sales

Cost of sales was ~~$55.8~~$98.9 million for the three months ended ~~June~~September 30, 2023, including expenses of ~~$19.8~~$81.6 million related to excess, obsolete, or expired inventory and losses on certain firm purchase commitments, $14.3 million related to unutilized manufacturing capacity, and a credit of ~~$17.9~~$21.5 million related to certain negotiated ~~certain~~ reductions to previously recognized firm purchase commitments. Cost of sales was ~~$271.1~~$434.6 million for the three months ended ~~June~~September 30, 2022, including expense of ~~$255.3~~$249.0 million related to excess, obsolete, or expired inventory and losses on firm purchase commitments. Prior to receiving regulatory approval, we expensed manufacturing costs as research and development expenses. After receiving regulatory approval, we capitalize the costs of production for a particular supply chain when we determine that we have a present right to the economic benefit associated with the product. While we tracked the quantities of our manufactured vaccine product and components, we did not track pre-approval manufacturing costs and therefore the manufacturing cost of our pre-launch inventory produced prior to approval is not reasonably determinable. However, based on our expectations for future manufacturing costs to produce our vaccine product and components inventory, we estimate at ~~June~~September 30, 2023, we had approximately ~~$25.9~~$24.3 million of salable commercial inventory that was expensed prior to approval. We expect to utilize the majority of our reduced-cost inventory through ~~2023.~~2024. If inventory sold for the three months ended ~~June~~September 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 ~~$71.7~~$103.2 million, an adjustment of ~~$15.9~~$4.3 million as compared to cost of sales recognized. If inventory sold for the three months ended ~~June~~September 30, 2022 was valued at expected standard cost, adjusted cost of sales for the period would have been approximately ~~$279.5~~$444.0 million, an adjustment of ~~$8.4~~$9.4 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.

Research and Development Expenses

Research and development expenses were ~~$219.5~~$106.2 million for the three months ended ~~June~~September 30, 2023 as compared to ~~$289.6~~$304.3 million for the three months ended ~~June~~September 30, 2022, a decrease of ~~$70.2~~$198.1 million. The decrease was primarily due to a reduction in overall expenditures relating to development activities on coronavirus vaccines, including ~~NVX-CoV2373 and XBB COVID vaccine,~~our COVID-19 Program, and CIC, as summarized in the table below (in thousands):

Research and development expenses for coronavirus vaccines for the three months ended ~~June~~September 30, 2023 and 2022 decreased from ~~$201.0~~$208.0 million to ~~$139.6~~$41.3 million primarily as a result of a reduction in manufacturing and support costs due, in part, to a reduction in our global manufacturing footprint consistent with our contractual obligations to supply, and anticipated demand for, COVID-19 Vaccine, including embedded lease costs, under manufacturing supply agreements with

Contract Manufacturing Organizations (“CMOs”) and contract manufacturing and development organizations (“CDMOs”),. The decrease was also due to a ~~reduction~~benefit of $57.7 million for the three months ended September 30, 2023 resulting from our settlement agreement and Private Placement with SK (see Note 4 to our consolidated financial statements in ~~clinical study costs and the commercialization of internal manufacturing~~

~~capabilities, as~~this Quarterly Report). The decrease was partially offset by a benefit ~~of $20.5~~$80.5 million ~~and $87.2 million, respectively,~~for the three months ended September 30, 2022 related to previously accelerated manufacturing costs for leases that we determined were embedded in manufacturing supply agreements with CMOs and CDMOs.

Selling, General, and Administrative Expenses

Selling, general, and administrative expenses were ~~$93.7~~$107.5 million for the three months ended ~~June~~September 30, 2023 as compared to ~~$108.2~~$122.9 million for the same period in 2022, a decrease of ~~$14.4~~$15.4 million. The decrease in selling, general, and administrative expenses is primarily due to certain cost containment measures to reduce our operating ~~spend, partially offset by restructuring expenses of $11.5 million.~~spend.

For the remainder of 2023, we expect a reduction in our annual combined research and development, and selling, general, and administrative spend as a result of our Restructuring Plan announced during the three months ended June 30, 2023.

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~~manufacturing and commercial support of ~~NVX-CoV2373 and variant candidates,~~our COVID-19 Program, including significant commitments under various ~~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”);~~EC; and various countries globally. We also have grant and license agreements. As of ~~June~~September 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 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 $2 billion, of which ~~$907.4~~$801.0 million is included in Deferred revenue in our ~~Consolidated~~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 APAs 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.~~trials. 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.~~COVID-19 Vaccine. Such upfront payments generally become non-refundable upon our achievement of certain development, regulatory, and commercial milestones.

On October 3, 2023, our updated vaccine received EUA from the U.S. FDA for active immunization to prevent COVID-19 in individuals aged 12 and older. Immediately upon authorization, our updated vaccine has also been included in the recommendations issued by the CDC on September 12, 2023. Doses became available within the U.S. at many major pharmacy retailers, following the Center for Biologics Evaluation and Research release of vaccine batches.

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~~agreed to pay up to ~~$185.0~~$185 million (the “Settlement Payment”) 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.~~each, which began on March 31, 2023. Under the Fujifilm Settlement Agreement, the final two quarterly installments due to Fujifilm were subject to Fujifilm’s obligation to use commercially reasonable efforts to mitigate losses associated with the vacant manufacturing capacity caused by the termination of manufacturing activities at FDBT under the CSA. Any replacement revenue achieved by Fujifilm’s mitigation efforts between July 1, 2023 and December 31, 2023 would offset the final two settlement payments owed by the Company. On October 2, 2023, we sent a notice of breach under the Fujifilm Settlement Agreement to Fujifilm setting forth the Company’s position that Fujifilm had not used commercially reasonable efforts to mitigate losses. We withheld the $34.3 million installment payment due to Fujifilm on September 30, 2023, pending resolution of the issues identified in the notice of breach. We paid the first ~~and second installment~~two installments of $68.6 million during the ~~three and six~~nine months ended ~~June~~September 30, 2023, ~~respectively,~~ and the remaining balance of $68.6 million is reflected in Accrued expenses in our consolidated balance sheet. On October 30, 2023, FDBT filed a demand for arbitration with Judicial Arbitration and Mediation Services (“JAMS”) seeking payment of the third quarter installment of the Settlement Payment.

In August 2023, we entered into a Settlement Agreement and General Release (the “Settlement Agreement”) with SK regarding the mutual release by the parties of all claims arising from or in relation to certain statements of work (“SOWs”) under the Development and Supply Agreement entered into in August 2020 and the Collaboration and License Agreement, entered into in February 2021 as amended in December 2021 and July 2022 in connection with the cessation of all drug substance and drug product manufacturing activity at SK for supply to us. Pursuant to the Settlement Agreement, we agreed to pay $149.8 million, of which (i) $130.4 million was paid in August 2023 and (ii) the remaining balance is to be paid on or before November 15, 2023. Under the Settlement Agreement, we also agreed with SK to a wind down plan with respect to the

remaining products, materials and equipment under the SOWs (see Note 4 to our consolidated financial statements in this Quarterly Report).

~~During April~~In August 2023, we ~~made~~entered into a ~~payment~~Securities Subscription Agreement (the “Subscription Agreement”) with SK, pursuant to which we agreed to sell and issue to SK, in a private placement (the “Private Placement”), 6.5 million shares of ~~$27.0 million~~our common stock, par value $0.01 per share at a price of $13.00 per share for aggregate gross proceeds to ~~Par Sterile Products, LLC (“Par”) under~~us of approximately $84.5 million. The closing of the ~~Settlement Agreement and Release of Claims~~Private Placement occurred on August 10, 2023 (see Note 154 to our consolidated financial statements in this Quarterly Report).

In addition, we continue to assess our manufacturing needs and modify our global manufacturing footprint consistent with our contractual obligations to supply, and anticipated demand for, ~~NVX-CoV2373,~~COVID-19 Vaccine, and in doing so recognize that significant costs may be incurred. We currently depend exclusively on SIIPL and SLS for co-formulation and filling (other than in Europe), and PCI Pharma Services for finishing ~~NVX-CoV2373~~COVID-19 Vaccine in Europe and any delays or disruptions in these suppliers’ operations could prevent or delay the delivery of customer orders.

We have an APA with the Commonwealth of Australia for the purchase of doses of ~~NVX-CoV2373~~COVID-19 Vaccine (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 that the total contract value of the Australia APA is maintained with doses to be 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 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 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~~COVID-19 Vaccine (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~~COVID-19 Vaccine previously scheduled for delivery, (ii) reducing the amount of doses of ~~NVX-CoV2373~~COVID-19 Vaccine due for delivery, (iii) revising the delivery schedule for the remaining doses of ~~NVX-CoV2373~~COVID-19 Vaccine 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,~~COVID-19 Vaccine, 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 deliver COVID-19 vaccine doses to the Canadian government byin the ~~second half~~fourth quarter of 2023, the second installment 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 we fail to achieve regulatory approval for use of BMC for ~~NVX-CoV2373~~COVID-19 Vaccine 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 Canadian government will endeavor to expand our previously agreed in-country commitment to Canada and to 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 our ability to deliver such benefits over a ~~15 year~~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. As of September 30, 2023, we are in the process of negotiating the MOU. 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 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 (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, dated October 22, 2020, between the parties (the “Original UK Supply Agreement”). Under the Original UK Supply Agreement, the Authority agreed to purchase 60 million doses of ~~NVX-CoV2373~~prototype vaccine 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,~~prototype vaccine, with the number of Conditional Doses contingent on, and subject to reduction based on, our timely achievement of supportive recommendations from the Joint Committee on Vaccination and Immunisation (the “JCVI”) that is approved by the UK Secretary of State for Health, with respect to use of 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,~~prototype vaccine, we would have to repay up to ~~$225.0~~$225 million related to the upfront payment previously received from the Authority under the Original UK Supply Agreement. Under the Amended and Restated UK Supply Agreement, the Authority also has the option to purchase up to an additional 44 million doses, in one or more tranches, through 2024.

As of November 30, 2022, the JCVI had not yet made a supportive recommendation with respect to ~~NVX-CoV2373,~~our prototype vaccine, 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, we 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~~our prototype vaccine by the WHO (the “Advance Payment Amount”). On November 18, 2022, we delivered written notice to Gavi to terminate the Gavi APA on the basis of Gavi’s failure to procure the purchase of 350 million doses of ~~NVX-CoV2373~~prototype vaccine 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~~September 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 International Court of Arbitration based on the claims described above. We filed our Answer and Counterclaims on March 2, 2023. On April 5, 2023, Gavi filed its Reply to our Counterclaims. The arbitration hearing is scheduled for July 2024, with a written decision to follow. Arbitration is inherently uncertain, and while we believe that we are entitled to retain the remaining Advance Payment Amount received from Gavi, it is possible that we will be required to refund all or a portion of the remaining Advance Payment Amount from Gavi.

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 of June 30,

~~2023 we had previously anticipated pursuant to the USG Agreement. 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~~prototype vaccine and development and regulatory milestones related to commercial readiness, expansion of the EUA and development of multiple vial presentations. ~~As of June 30, 2023, we constrained $48.0 million of these contingent~~We expect to substantially meet milestones ~~related that we are eligible to recognize in~~and other performance requirements under the ~~2023 fall vaccination campaign.~~

USG Agreement by December 31, 2023.

Our funding agreements currently include funding from the Coalition 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~~COVID-19 Vaccine 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~~September 30, 2023, we had ~~$517.9~~$666.4 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~~nine months ended ~~June~~September 30, 2023 primarily with cash and cash equivalents, ~~and~~ revenue from product sales, together with revenue under the USG Agreement that support our ~~NVX-CoV2373 vaccine~~COVID-19 Vaccine development ~~activities.~~activities and the sale of our common stock under our June 2021 and August 2023 Sales Agreements. 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, revenue under our USG Agreement, our cash and cash equivalents, and other potential funding ~~sources.~~sources including equity financings, which may include at-the-market offerings under our August 2023 Sales Agreement, debt financings, collaborations, strategic alliances, and marketing, distribution or licensing arrangements.

The following table summarizes cash flows for the ~~six~~nine months ended ~~June~~September 30, 2023 and 2022 (in thousands):

Net cash used in operating activities was ~~$497.5~~$537.2 million for the ~~six~~nine months ended ~~June~~September 30, 2023, as compared to ~~$259.4~~$298.1 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~~$49.7 million for the ~~six~~nine months ended ~~June~~September 30, 2023, as compared to ~~$41.4~~$70.9 million for the same period in 2022. The decrease in cash used in investing activities is primarily due to lower ~~expenditure~~expenditures on equipment and leasehold improvements.

Net cash used in financing activities was ~~$293.0~~$95.9 million for the ~~six~~nine months ended ~~June~~September 30, 2023, as compared to net cash provided by finance activities of ~~$164.5~~$133.5 million for the same period in 2022. The increase in cash used in financing activities in 2023 as compared with 2022, is primarily due to the $325 million repayment of our 3.75% Convertible notes during 2023, ~~and~~partially offset by an increase in net proceeds ~~of approximately $179 million~~ from the sales of our common stock under our June 2021 and August 2023 Sales ~~Agreement during 2022.~~Agreements and the Private Placement with SK.

Going Concern

The accompanying unaudited consolidated financial statements in Part I, Item 1, “Consolidated Financial Statements” of this Quarterly Report have been prepared assuming that we will continue as a going concern within one year after the date that the financial statements are issued. At ~~June~~September 30, 2023, we had ~~$517.9~~$666.4 million in cash and cash equivalents and restricted cash. During the ~~six~~nine months ended ~~June~~September 30, 2023, we incurred a net loss of ~~$235.9~~$366.7 million and had net cash flows used in operating activities of ~~$497.5~~$537.2 million.

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. 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,~~our ability to execute on certain cost-cutting initiatives 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 a vaccine candidate for~~our COVID-19 Vaccine for the ~~fall 2023 COVID vaccine~~2023-2024

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~~payments which could adversely affect our ability 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 fundingcontinue as ~~of June 30, 2023 we had previously anticipated.~~a going concern. 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~~Payment Amount of $696.4 million as of ~~June~~September 30, 2023. See Note 3 and Note 1514 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,~~COVID-19 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~~Company 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~~$14.6 million during the ~~three~~nine months ended ~~June~~September 30, 2023. See Note 1615 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~~authorization and are successfully commercialized, and in particular ~~the 2023 Fall~~our 2023-2024 vaccination ~~campaign,~~season, which is inherently uncertain and subject to a number of risks, including the incidence of COVID-19 during the 2023-2024 vaccination season, regulatory authorization, ability to timely deliver doses and achieve commercial adoption and market ~~acceptance;~~acceptance of our updated vaccine; 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, asset sales 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, asset sales 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~~our COVID-19 Program and our other vaccine candidates, including an influenza vaccine candidate and a CIC vaccine candidate, ~~or a~~remains uncertain. Also, the impact of our more focused investment in our COVID-19 ~~variant strain-containing monovalent formulation, remains~~Program, reduction to our pipeline spending, continued rationalization of our manufacturing network, reduction to our global workforce, and consolidation of our facilities and infrastructure remain 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 about Market Risk

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

Foreign Currency Exchange Risk

Although we are headquartered in the U.S. our results of operations, including our foreign subsidiaries’ operations, are subject to foreign currency exchange rate fluctuations, primarily the U.S. dollar against the Euro, Pound Sterling, Swedish Krona, and Czech Koruna. This exchange exposure may have a material effect on our cash and 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

3842

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 for 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 subsidiaries would result in a decline of stockholders’ equity (deficit) of approximately ~~$20~~$24 million as of ~~June~~September 30, 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 interest rate risk is primarily confined to our investment ~~portfolio, which historically has been classified as available-for-sale.~~portfolio. 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 ~~June~~September 30, 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.

Item 1. Legal Proceedings

Stockholder Litigation

On July 21, 2022, the Maryland Court issued a memorandum opinion and order remanding the Kirst Action to state court. On December 6, 2022, the parties to the Kirst Action filed a stipulated schedule pursuant to which the plaintiffs were expected to file an amended complaint on December 22, 2022, and either (i) the parties would file a stipulated stay of the Kirst Action or (ii) the defendants would file a motion to stay the case by January 23, 2023. The plaintiffs filed an amended complaint on December 30, 2022. On January 23, 2023, defendants filed a motion to stay the Kirst action. On February 22, 2023, the parties in the Kirst Action filed for the Court’s approval of a stipulation staying the Kirst Action pending the resolution of defendants’ motion to dismiss in the Second Consolidated Derivative Action. On March 22, 2023, the Court entered an order staying the Kirst Action pending resolution of the ~~Motion~~motion to ~~Dismiss~~dismiss in the Second Consolidated Derivative Action.

The parties continue to discuss next steps in the litigation following the Maryland Court’s ruling on the motion to dismiss the Second Consolidated Derivative Action.

On February 26, 2021, a Company stockholder named Thomas Golubinski filed a derivative complaint against members of the Company’s board of directors and members of senior management in the Delaware 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 on May 3, 2021. The results of the vote were disclosed in the Company’s Current Report on Form 8-K filed 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. On October 18, 2022, the Delaware Court denied the plaintiff’s fee application in its entirety. Under a prior Delaware Court order, the case was automatically dismissed with prejudice upon denial of the plaintiff’s fee application. On November 14, 2022, Golubinski filed a Notice of Appeal in the Supreme Court of the State of Delaware. The plaintiff / appellant filed his opening appellate brief on December 30, 2022. The Company filed its responsive brief on January 30, 2023 and the appellant filed his reply brief on February 14, 2023. On June 8, 2023, the Supreme Court affirmed the Court of Chancery’s denial of the plaintiff’s fee application. The case was closed on June 26, 2023.

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~~prototype vaccine 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~~September 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 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 2024, with a written decision to follow. Arbitration is inherently uncertain, and while we believe that we are entitled to retain the remaining Advance Payment Amount received from Gavi, it is possible that we could be required to refund all or a portion of the remaining Advance Payment Amount from Gavi.

On September 30, 2022, the Company, FUJIFILM Diosynth Biotechnologies UK Limited (“FDBK”), FUJIFILM Diosynth Biotechnologies Texas, LLC (“FDBT”), and FUJIFILM Diosynth Biotechnologies USA, Inc. (“FDBU” and together with FDBK and FDBT, “Fujifilm”) entered into a Confidential Settlement Agreement and Release (the “Fujifilm Settlement Agreement”) regarding amounts due to Fujifilm in connection with the termination of manufacturing activity at FDBT under the Commercial Supply Agreement (the “CSA”) dated August 20, 2021 and Master Services Agreement dated June 30, 2020 and associated statements of work (the “MSA”) by and between the Company and Fujifilm. The MSA and CSA established the general terms and conditions applicable to Fujifilm’s manufacturing and supply activities related to the Company’s prototype vaccine under the associated statements of work. Pursuant to the Fujifilm Settlement Agreement, the Company agreed to pay up to $185.0 million (the “Settlement Payment”) to Fujifilm in connection with cancellation of manufacturing activity at FDBT. Under the Fujifilm Settlement Agreement, the final two quarterly installments due to Fujifilm were subject to Fujifilm’s obligation to use commercially reasonable efforts to mitigate losses associated with the vacant manufacturing capacity caused by the termination of manufacturing activities at FDBT under the CSA. Any replacement revenue achieved by Fujifilm’s mitigation efforts between July 1, 2023 and December 31, 2023 would offset the final two settlement payments owed by the Company. On October 2, 2023, the Company sent a notice of breach under the Fujifilm Settlement Agreement to Fujifilm setting forth the Company’s position that Fujifilm had not used commercially reasonable efforts to mitigate losses. The Company withheld the $34.3 million installment payment due to Fujifilm on September 30, 2023, pending resolution of the issues identified in the notice of breach. On October 30, 2023, FDBT filed a demand for arbitration with JAMS seeking payment of the withheld installment payment.

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, 2022, which was filed with the SEC on February 28, 2023, and Part II, Item 1A. “Risk Factors” of our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2023, which was filed with the SEC on May 9, 2023 and our Quarterly Report on Form 10-Q for the quarter ended June 30, 2023, which was filed with the SEC on August 8, 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, 2022, ~~and~~ the Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2023 and the Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 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~~September 30, 2023, we had ~~$517.9~~$666.4 million in cash and cash equivalents and restricted cash. During the ~~six~~nine months ended ~~June~~September 30, 2023, we incurred a net loss of ~~$235.9~~$366.7 million and had net cash flows used in operating activities of ~~$497.5~~$537.2 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: ~~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~~its COVID-19 Vaccine for the ~~fall 2023 COVID vaccine~~2023-2024 vaccination 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.~~

4246

• 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 1514 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;~~commercialized, and in particular the 2023-2024 vaccination season, which is inherently uncertain and subject to a number of risks, including the incidence of COVID-19 during the 2023-2024 vaccination season, regulatory authorization, ability to timely deliver doses and achieve commercial adoption and market acceptance of its updated vaccine; 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, asset sales 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,~~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, asset sales 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~~Program and our other vaccine candidates, including an influenza vaccine candidate and CIC vaccine candidate, ~~or a~~remains uncertain. Also, the impact of the Company’s more focused investment in its COVID-19 ~~variant strain-containing monovalent formulation, remains~~Program, reduction to its pipeline spending, continued rationalization of its manufacturing network, reduction to its global workforce, and consolidation of its facilities and infrastructure remain 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~~

Item 2. Unregistered Sales of Equity Securities, Use of Proceeds, and ~~Compliance Matters~~Issuer Purchases of Equity Securities

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~~On August 8, 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~~Securities Subscription Agreement ~~and Release~~(the “Subscription Agreement”) with ~~FUJIFILM under~~SK, pursuant to 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 sell and issue to SK, in a private placement (the “Private Placement”), 6.5 million shares of the Company’s common stock, par value $0.01 per share at a price of $13.00 per share for aggregate gross proceeds to us of approximately ~~$95 million in fees owed to AGC Biologics in connection with~~$84.5 million. The proceeds from 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 commercializationPrivate Placement will be ~~delayed,~~used for general corporate purposes, including but not limited to, working capital, capital expenditures, research 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 producedevelopment expenditures, 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;~~

•~~shipment delays or other supply chain disruptions~~

•~~quality control and assurance;~~

•~~contamination, lot consistency, potency, and purity;~~

•~~shortages of qualified personnel~~trial expenditures, commercialization activities, acquisitions and other ~~capacity constraints;~~

•~~compliance with strictly enforced and evolving federal, state and foreign regulations that vary~~strategic purposes. We recognized the shares at the settlement date fair value of $46.5 million (see Note 4 to our consolidated financial statements in ~~each country where products might be sold including nationalization or other territory restrictions placed~~this Quarterly Report). The closing of the Private Placement occurred 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.~~August 10, 2023.

Item 5. Other Information

During the three months ended ~~June~~September 30, 2023, no director or “officer” (as defined in Rule 16a-1(f) under the Securities Exchange Act of 1934, as amended) of the Company adopted or terminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K.
