NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

June 30, 2024

(unaudited)

Note 1 – Organization and Business

Novavax, Inc. (“Novavax,” and together with its wholly owned subsidiaries, the “Company”) is a global company that is advancing protein-based vaccines with its Matrix-MTM adjuvant. Novavax offers a differentiated vaccine platform that combines a recombinant protein approach, innovative nanoparticle technology, and patented Matrix-M™ adjuvant to enhance the immune response. In May 2024, Novavax entered into a collaboration and licensing agreement (the “Collaboration and License Agreement” or “ Sanofi CLA”) with Sanofi Pasteur Inc. (“Sanofi”) to co-commercialize Novavax’s current standalone COVID-19 vaccines (“COVID-19 Vaccine”), including Novavax’s NuvaxovidTM, prototype COVID-19 vaccine (“NVX-CoV2373,” or “prototype vaccine”) and XBB COVID-19 vaccine (“NVX-CoV2601”), and the Company’s updated vaccine for the 2024-2025 vaccination season (“NVX-CoV2705,” or “updated vaccine” and, collectively with NVX-CoV2373 and NVX-CoV2601, the Company’s “COVID-19 Vaccine” or “COVID-19 Program”). This agreement is discussed in greater detail in Note 6 of Novavax’s consolidated financial statements. The partnership with Sanofi allows Novavax to broaden access to its vaccine and adjuvant and refocus on clinical-stage research and development and pipeline expansion beginning in 2025.

Through the end of the 2024-2025 vaccination season, Novavax will continue commercialization of its COVID-19 Vaccine. Local regulatory authorities have also specified nomenclature for the labeling of NVX-CoV2373 and NVX-CoV2601 within their territories (e.g., “Novavax COVID-19 Vaccine, Adjuvanted”, “Novavax COVID-19, Adjuvanted (2023-2024 Formula),” respectively, for the U.S., and “Nuvaxovid™” for ex-US territories) collectively referred to as the Company’s “COVID-19 Program,” or “COVID-19 Vaccine”).

In 2024, the Company has submitted an amendment to the previously granted October 2023 Emergency Use Authorization (“EUA”) to the U.S. Food and Drug Administration (“U.S. FDA”), filed for a type II variation of the existing Marketing Authorization (“MA”) with the European Medicines Agency (“EMA”) and the United Kingdom's (“U.K.”) Medicines and Healthcare products Regulatory Agency (“MHRA”), and filed for authorization with Health Canada for the Company’s updated vaccine. Currently, the Company significantly depends on its supply agreement with Serum Institute of India Pvt. Ltd. (“SII”) and its subsidiary, Serum Life Sciences Limited (“SLS” and together with SII, “Serum”), for co-formulation, filling, and finishing (other than in Europe) and on its service agreement with PCI Pharma Services for finishing in Europe.

Novavax is advancing development of other vaccine candidates, including its COVID-19-Influenza Combination (“CIC”) and stand-alone influenza vaccine candidates. In addition, Novavax’s adjuvant is included in the University of Oxford and SII’s R21/Matrix-MTM malaria vaccine which has received authorizations in a number of countries with doses administered in 2024. Novavax’s COVID-19 Vaccine 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 income (loss), changes in stockholders’ 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. The aggregate foreign currency transaction gains and losses resulting from the conversion of the transaction currency to functional currency were a $1.6 million loss and a $6.7 million loss, and a $0.2 million loss and $16.1 million gain for the three and six months ended June 30, 2024 and 2023, 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, 2023. 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 consolidated financial statements have been prepared assuming that the Company will continue as a going concern within one year after the date that the financial statements are issued and contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of the uncertainty described below.

In May 2024, the Company entered into the Sanofi CLA and a securities subscription agreement (the “Subscription Agreement”) with Sanofi as a result of which, the Company received a total of $568.8 million during the second quarter of 2024 (See Note 6).

As of June 30, 2024, the Company had $680.2 million in cash and cash equivalents, $369.4 million in marketable securities, and working capital of $45.6 million. During the six months ended June 30, 2024, the Company recognized net income of $14.8 million, and had net cash flows provided by operating activities of $230.7 million.

In accordance with Accounting Standards Codification (“ASC”) Topic 205-40, Presentation of Financial Statements - Going Concern, the Company evaluated its ability to continue as a going concern within one year after the date that these consolidated financial statements are issued. Based on the Company’s current cash and cash equivalents and marketable securities balances and its current cash flow forecast for the one-year going concern look forward period, the Company has concluded that it will have sufficient capital available to fund its operations for the one-year period from the date that these financial statements are issued. As of December 31, 2023, the Company had concluded that there was substantial doubt about its ability to continue as a going concern primarily due to significant uncertainty related to its ability to successfully develop, manufacture, distribute, and market its updated vaccine and execute on certain cost-reduction initiatives as described in Note 16. The Sanofi CLA has alleviated the substantial doubt.

Revenue Recognition, Licensing and Transition Services

The terms of the Company’s third-party licensing agreements may contain multiple performance obligations, including licenses and transition services. The Company evaluates licensing agreements under ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”) to determine the distinct performance obligations. Prior to recognizing revenue, the Company estimates the transaction price, including variable consideration that is subject to a constraint. Amounts of variable consideration are included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur and when the uncertainty associated with the variable consideration is subsequently resolved. Total consideration may include nonrefundable upfront license fees, transition service fees, other payments based upon the achievement of specified milestones, and royalty payments based on product sales from licensed products.

For multiple performance obligation arrangements, the Company allocates the transaction price to each distinct performance obligation based on its relative standalone selling price. The standalone selling price is generally determined for each performance obligation based on the prices charged to customers, discounted cash flows, or using expected cost-plus margin. For standalone selling prices determined using discounted cash flows, the Company considers discounted, probability-weighted cash flows related to the performance obligation transferred. In developing such estimates, the Company applies judgment in determining the forecasted revenue, expected margins, and the discount rate. These estimates are subjective and require the Company to make assumptions about future cash flows. Revenue related to performance obligations satisfied at a point in time is recognized when the customer obtains control of the promised asset. For performance obligations recognized over time, the Company recognizes revenue using an input method to measure progress by utilizing costs incurred to-date relative to total expected costs. Under this process, the Company considers the costs that have been incurred to-date, as well as projections to completion using various inputs and assumptions, including, but not limited to, progress towards completion, labor costs and level of effort, material and subcontractor costs, and indirect administrative costs. Estimating the total cost at completion of the Company’s performance obligation under a contract is subjective and requires the Company to make assumptions about future activity and cost drivers. Changes in these estimates can occur for a variety of reasons and may impact the timing of revenue recognition on the Company’s contracts. Changes in estimates related to the process are recognized in the period when such changes are made on a cumulative catch-up basis. The Company has not experienced any material adjustments as a result of changes in estimates arising from this process.

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.

Restructuring

The Company recognizes restructuring charges when such costs are incurred. The 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 16 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 as defined in Note 16.

Recent Accounting Pronouncements

Not Yet Adopted

In October 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-06, Disclosure Improvements (“ASU 2023-06”), to clarify or improve disclosure and presentation requirements of a variety of topics and align the requirements in the FASB ASC with the SEC's regulations. The Company is currently evaluating ASU 2023-06 to determine its impact on the Company's consolidated financial statements and disclosures.

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (“ASU 2023-09”). The standard enhances transparency in income tax disclosures by requiring, on an annual basis, certain disaggregated information about a reporting entity’s effective tax rate reconciliation and income taxes paid. The ASU also requires disaggregated disclosure related to pre-tax income (or loss) and income tax expense (or benefit) and eliminates certain disclosures related to the balance of an entity’s unrecognized tax benefit and the cumulative amount of certain temporary differences. The ASU is effective for the Company beginning on January 1, 2025. The Company is currently evaluating ASU 2023-09 to determine its impact on the Company's disclosures.

Note 3 – Marketable Securities

Marketable securities were classified as available-for-sale as of June 30, 2024 and comprised of (in thousands):


	June 30, 2024	December 31, 2023
			Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses		Fair Value		Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses		Fair Value
Corporate debt securities			$	369,582	$	—	$	(150)	$	369,432	$	—	$	—	$	—	$	—
Total marketable securities			$	369,582	$	—	$	(150)	$	369,432	$	—	$	—	$	—	$	—

As of June 30, 2024, investments in marketable securities, comprising corporate debt securities, were due to mature within one year. Based on the Company’s policy under the expected credit loss model, including an assessment of unrealized losses on the portfolio as of June 30, 2024, the Company concluded that the unrealized losses for its marketable securities were not attributable to credit and therefore an allowance for credit losses for these securities has not been recorded as of June 30, 2024. Also, based on the scheduled maturities of the investments, the Company was more-likely-than-not to hold these investments for a period of time sufficient for a recovery of the Company’s cost basis. As of June 30, 2024, the Company held no securities that were in an unrealized loss position for more than 12 months.

Note 4– Fair Value Measurements

The following table represents the Company’s fair value hierarchy for its financial assets and liabilities (in thousands):


	Fair Value at June 30, 2024						Fair Value at December 31, 2023
Assets	Level 1		Level 2		Level 3		Level 1		Level 2		Level 3
Money market funds(1)	$	188,086	$	—	$	—	$	171,824	$	—	$	—

(1)Classified as cash and cash equivalents as of June 30, 2024 and December 31, 2023, respectively, on the consolidated balance sheets.

(2)Includes $232.0 million classified as Cash and cash equivalents and $369.4 million classified as marketable securities as of June 30, 2024, on the consolidated balance sheets.

Fixed-income investments categorized as Level 2 are valued at the custodian bank by a third-party pricing vendor’s valuation models that use verifiable observable market data, such as interest rates and yield curves observable at commonly quoted intervals and credit spreads, bids provided by brokers or dealers, or quoted prices of securities with similar characteristics. Pricing of the Company’s convertible notes has been estimated using observable inputs, including the price of the Company’s common stock, implied volatility, interest rates, and credit spreads.

During the six months ended June 30, 2024 and 2023, the Company did not have any transfers between levels.

The amount in the Company’s consolidated balance sheets for accounts payable and accrued expenses approximates its fair value due to its short-term nature.

Note 5 – Revenue

The Company's accounts receivable included $29.8 million and $286.4 million related to amounts that were billed to customers and $2.3 million and $10.8 million related to amounts which had not yet been billed to customers as of June 30, 2024 and December 31, 2023, respectively. During the six months ended June 30, 2024 and 2023, changes in the Company’s accounts receivables, allowance for credit losses, and deferred revenue balances were as follows (in thousands):


	Balance, Beginning of Period		Additions		Deductions		Balance, End of Period
Accounts receivable:
Six Months Ended June 30, 2024	$	304,916	$	672,326	$	(937,462)	$	39,780
Six Months Ended June 30, 2023	96,210		793,039		(486,684)		402,565
Allowance for credit losses(1):
Six Months Ended June 30, 2024	$	(7,675)	$	—	$	—	$	(7,675)
Six Months Ended June 30, 2023	(13,835)		—		6,160		(7,675)
Deferred revenue:(2)
Six Months Ended June 30, 2024	$	863,520	$	365,150	$	(28,849)	$	1,199,821
Six Months Ended June 30, 2023	549,551		414,816		(56,957)		907,410

(1) There was no allowance for credit losses recorded during the six months ended June 30, 2024 or 2023. During the six months ended June 30, 2023, there was a $6.2 million reversal of a credit loss allowance due to the collection of a previously recognized allowance for credit losses. To estimate the allowance for credit losses, 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 six months ended June 30, 2024, deductions included a $2.2 million reclassification of refundable upfront payments previously included in Deferred revenue to Other current liabilities. During the six months ended June 30, 2024, additions included a $225.0 million reclassification of refundable upfront payment from Other current liabilities to Deferred revenue related to the settlement with Gavi as discussed below. There were no such reclassifications during the six months ended June 30, 2023.

As of June 30, 2024, the aggregate amount of the transaction price allocated to performance obligations that were unsatisfied (or partially unsatisfied), excluding amounts related to sales-based royalties and constrained variable consideration, was approximately $2 billion, of which $1.2 billion was included in Deferred revenue. Failure to meet regulatory milestones, obtain timely supportive recommendations from governmental advisory committees, or achieve product volume or delivery timing obligations under the Company’s APAs 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 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 the Company’s updated vaccine under certain of the Company’s APAs.

Under an APA with Gavi, the Vaccine Alliance (“Gavi”), entered into in May 2021 (the “Gavi APA”), the Company received upfront payments of $700 million from Gavi (the “Advance Payment Amount”) to be applied against purchases of the Company’s prototype vaccine by certain countries participating in the COVAX Facility. As of December 31, 2023, the remaining Gavi Advance Payment Amount was $696.4 million. In February 2024, the Company entered into a Termination and Settlement Agreement with Gavi (the “Gavi Settlement Agreement”) terminating the Gavi APA, settling the arbitration proceedings, and releasing both parties of all claims arising from, under, or otherwise in connection with the Gavi APA. On February 22, 2024, the claims and counterclaims were dismissed with prejudice. Pursuant to the Gavi Settlement Agreement, the Company is responsible for payment to Gavi of (i) an initial settlement payment of $75 million, which the Company paid in February 2024, and (ii) deferred payments, in equal annual amounts of $80 million payable each calendar year through a deferred payment term ending December 31, 2028. The deferred payments are due in variable quarterly installments and total $400 million during the deferred payment term. Such deferred payments may be reduced through Gavi’s use of an annual vaccine credit equivalent to the unpaid balance of such deferred payments each year, which may be applied to qualifying sales of any of the Company’s vaccines for supply to certain low-income and lower-middle income countries. The Company has the right to price the vaccines offered to such low-income and lower-middle income countries in its discretion, and, when utilized by Gavi, the Company will credit the actual price per vaccine paid against the applicable credit. The Company intends to price

vaccines offered via the tender process, consistent with its shared goal with Gavi to provide equitable access to those countries. Also, pursuant to the Gavi Settlement Agreement, the Company granted Gavi an additional credit of up to $225 million that may be applied against qualifying sales of any of the Company’s vaccines for supply to such low-income and lower-middle income countries that exceed the $80 million deferred payment amount in any calendar year during the deferred payment term. In total, the Gavi settlement agreement is comprised of $700 million of potential consideration, consisting of the $75 million initial settlement payment, deferred payments of up to $400 million that may be reduced through annual vaccine credits, and the additional credit of up to $225 million that may be applied for certain qualifying sales.

The Company recorded the $3.6 million difference between the refund liability recorded as of December 31, 2023 of $696.4 million and the $700 million of total consideration under the arrangement as a reduction to revenue during the six months ended June 30, 2024. As of June 30, 2024, the remaining amounts included on the Company’s consolidated balance sheet were $225 million in non-current Deferred revenue for the additional credit that may be applied against future qualifying sales, $90 million in Other current liabilities, and $305 million in Other non-current liabilities. In addition, the Company and Gavi entered into a security agreement pursuant to which Novavax granted Gavi a security interest in accounts receivable from SII under the SII R21 Agreement (see Note 6), which will continue for the deferred payment term of the Gavi Settlement Agreement.

Product Sales

Product sales by the Company’s customer’s geographic location was as follows (in thousands):


	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
North America	$	1,607	$	—	$	(4,755)	$	—
Europe	169		1,518		90,586		58,785
Rest of the world	18,128		283,645		16,397		218,921
Total product sales revenue	$	19,904	$	285,163	$	102,228	$	277,706

Product sales in the U.S. are primarily made through large pharmaceutical wholesale distributors at the wholesale acquisition cost (“WAC”). Product sales in the U.S. are recorded net of gross-to-net deductions. During the six months ended June 30, 2024, product sales in North America includes $4.8 million of gross-to-net deductions in excess of the WAC, primarily due to wholesale distributor fees for shipments expected to be returned and adjustments made to estimated returns of prior period product sales, partially offset by updates to estimated product returns. During the six months ended June 30, 2024, product sales for the rest of the world includes a $3.6 million reduction to revenue recognized pursuant to the Gavi Settlement Agreement as discussed above.

As of June 30, 2024, changes in the Company’s gross-to-net deductions balances were as follows (in thousands):


	Wholesale Distributor Fees, Discounts, and Chargebacks		Product Returns		Total
Balance as of December 31, 2023	$	21,072	$	84,616	$	105,688
Amounts charged against product sales(1)	15,436		21,302		36,738
Credits/deductions	(35,621)		(51,331)		(86,952)
Balance as of June 30, 2024	$	887	$	54,587	$	55,474

(1) Amounts charged against product sales include $4.0 million of adjustments made to prior period product sales due primarily to changes in the estimate of product returns.

As of June 30, 2024 no gross-to-net deductions were included in Accounts receivable. As of December 31, 2023, $2.6 million of gross-to-net deductions were included in Accounts receivable. As of June 30, 2024 and December 31, 2023, $55.5 million and $103.1 million of gross-to-net deductions were included in Accrued expenses, respectively.

The Company has an APA with the Commonwealth of Australia (“Australia”) for the purchase of doses of COVID-19

Vaccine (the “Australia APA”). In March 2024, the Company and Australia agreed to cancel the COVID-19 Vaccine doses previously scheduled for delivery in the fourth quarter of 2023. As a result of the cancellation, the total contract value was reduced by $54.0 million, including $6.0 million of deferred revenue related to the cancelled doses that will be applied as a credit towards future deliveries of doses. Australia is not required to purchase updated vaccine doses until the Company receives authorization from Therapeutic Goods Administration (“TGA”). The Company does not expect approval in time for product delivery in 2024 which could result in a loss or deferral of approximately $240 million of contract value. The Company plans to seek an amendment to the Australia APA which may not be achievable on acceptable terms or at all. As of June 30, 2024, $119.1 million was classified as current Deferred revenue and $14.7 million was classified as non-current Deferred revenue with respect to the Australia APA in the Company’s consolidated balance sheet. If the Company is unable to satisfy its obligations under the Australia APA, $92.5 million of deferred revenue may become refundable and approximately $225 million of remaining funds under the contract may no longer be available.

The Company has 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 COVID-19 Vaccine (the “Canada APA”). The Canadian government may terminate the Canada APA, as amended, if the Company fails to receive regulatory approval for its COVID-19 Vaccine using bulk antigen produced at Biologics Manufacturing Centre (“BMC”) Inc. on or before December 31, 2024. The Company does not anticipate achieving regulatory approval of its COVID-19 Vaccine using bulk antigen produced at BMC on or before December 31, 2024. Therefore, the Company plans to seek an amendment to the Canada APA to address possible alternatives, which may not be achievable on acceptable terms or at all. As of June 30, 2024, $452.1 million was classified as current Deferred revenue and $136.1 million was classified as non-current Deferred revenue with respect to the Canadian APA in the Company’s consolidated balance sheet. If the Canadian government terminates the Canada APA, $28.0 million of the deferred revenue would become refundable and approximately $224 million of the contract value related to future deliverables would no longer be available.

In July 2024, the Pharmaceutical Management Agency (“Pharmac”), a New Zealand Crown entity, provided notice of its termination of its APA (the “New Zealand APA”). As of June 30, 2024, $31.3 million was classified as current Deferred revenue with respect to such agreement in the Company’s consolidated balance sheet. New Zealand has requested a refund of certain advanced payments and the Company is in discussion with Pharmac on both, whether its termination of the New Zealand APA was appropriate under the New Zealand APA, and whether a refund of the advanced payments is appropriate under the New Zealand APA. Approximately $125 million of the contract value related to future deliverables may no longer be available if the APA is terminated.

Licensing, Royalties, and Other

Licensing, royalties, and other includes Licensing payments, Transition Services revenue, and Technology Transfer revenue from the Company’s Collaboration and License Agreement with Sanofi (“Sanofi CLA”); royalty milestone payments; sales-based royalties; and Matrix-M™ adjuvant sales.

During the three and six months ended June 30, 2024, respectively, the Company recognized $386.3 million and $390.3 million in revenue related to license fees and $2.7 million and $10.2 million in revenue related to Matrix-M™ adjuvant sales, respectively. During the three and six months ended June 30, 2024, the Company recognized $6.6 million of Transition Services revenue.

During the three and six months ended June 30, 2023, the Company recognized $2.2 million and $3.2 million in revenue related to Matrix-M™ adjuvant sales. During the three and six months ended June 30, 2023, the Company did not recognize revenue related to license fees or milestone payments.

Grants

The Company’s U.S. government agreement consisted 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 the “USG Agreement”). As of December 31, 2023, the Company recognized the full $1.8 billion funding in revenue.

Note 6 – Collaboration, License, and Supply Agreements

As of June 30, 2024, the Company’s material collaborations, license and supply agreements were as follows:

Serum

The Company previously granted SII exclusive and non-exclusive licenses for the development, co-formulation, filling and finishing, registration, and commercialization of its prototype vaccine, NVX-CoV2601, its updated vaccine, and its CIC vaccine candidate. SII agreed to purchase the Company's Matrix-M™ adjuvant and the Company granted SII a non-exclusive license to manufacture the antigen drug substance component of the Company’s COVID-19 Vaccine in SII’s licensed territory solely for use in the manufacture of COVID-19 Vaccine. The Company and SII equally split the revenue from SII’s sale of COVID-19 Vaccine in its licensed territory, net of agreed costs. In May 2024, the Company and SLS entered into a supply agreement (the “SLS Supply Agreement”) under which SLS will supply the Company with antigen drug substance and finished COVID-19 Vaccine doses. The SLS Supply Agreement includes the general terms and conditions of supply orders between the Company and SLS. The Company and SLS intend to execute statements of work and firm purchase orders to included specific quantities to be delivered under the SLS Supply Agreement. The Company will supply SLS with all Matrix-M™ adjuvant needed to manufacture finished COVID-19 Vaccine doses. In March 2020, the Company entered into an agreement with SII that granted SII a non-exclusive license for the use of Matrix-M™ adjuvant supplied by the Company to develop, manufacture, and commercialize R21/Matrix-M™ adjuvant (“SII R21 Agreement”), a malaria vaccine created by the Jenner Institute, University of Oxford (“R21/Matrix-M™”). In December 2023, R21/Matrix-M™ received prequalification by the World Health Organization (“WHO”). Under the SII R21 Agreement, SII purchases the Company's Matrix-M™ adjuvant for use in development activities at cost and for commercial purposes at a tiered commercial supply price, and pays 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.

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 the Company’s COVID-19 Vaccine in Japan. Under the agreement, Takeda purchases Matrix-M™ adjuvant from the Company to manufacture doses of 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 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 its prototype vaccine. In February 2023, MHLW 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.

Sanofi

In May 2024, the Company entered into the Sanofi CLA under which the Company granted and Sanofi received the following:

i) A co-exclusive license to commercialize the Company’s current stand-alone COVID-19 Vaccine, including the Company’s prototype vaccine and updated vaccines, that address seasonal variants throughout the world (the “COVID-19 Vaccine Products”);

ii) A sole license to develop and commercialize combination products containing a potential combination of the Company’s COVID-19 Vaccine and Sanofi’s seasonal influenza vaccine (“COVID-19 and influenza Combination Products” or “CIC Products”);

iii) A non-exclusive license to develop and commercialize combination products containing both the Company’s COVID-19 Vaccine and one or more non-influenza vaccines (“Other Combination Products” and together with the COVID-19 Vaccine Products, CIC Products, and Other Combination Products, “Licensed COVID-19 Products”); and

iv) A non-exclusive license to develop and commercialize other vaccine products selected by Sanofi that include the Company’s Matrix-M™ adjuvant (as described below, the “Adjuvant Products”).

The Company is also responsible for performing services related to the technology transfer of its manufacturing process for the COVID-19 Vaccine Products and Matrix-M™ components to Sanofi. Until the successful completion of such transfer, the Company will supply Sanofi with both COVID-19 Vaccine Products and Matrix-M™ intermediary components for Sanofi’s use and is eligible for reimbursement of such costs from Sanofi. In addition, the Company is responsible for certain research and development and medical affairs services related to the COVID-19 Vaccine.

Under the Sanofi CLA, the Company will continue to commercialize its updated vaccine. Beginning in 2025 and continuing during the term of the Sanofi CLA, Sanofi and the Company will commercialize the COVID-19 Vaccine Products worldwide in accordance with a commercialization plan agreed by the Company and Sanofi, under which the Company will continue to supply its existing APA customers and strategic partners, including Takeda and SII. Upon completion of the existing APAs, the Company and Sanofi will jointly agree on commercialization activities of each party in each jurisdiction.

Pursuant to the Sanofi CLA, the Company received a non-refundable upfront payment of $500 million in the second quarter of 2024. In addition, the Company will also be eligible to receive development, technology transfer, launch, and sales milestone payments totaling up to $700 million in the aggregate with respect to the COVID-19 Vaccine Products and royalty payments on Sanofi’s sales of such licensed products. Milestone payments are comprised of a payment of $175 million upon the approval of the marketing authorization for a COVID-19 Vaccine Product in a pre-filled syringe from the FDA, $25 million upon the transfer of such approval to Sanofi, $25 million upon the transfer of EMA approval of a COVID-19 Vaccine Product in a pre-filled syringe to Sanofi, $50 million upon database lock of an existing Phase 2/3 clinical trial (identifier 2019nCoV-503), $75 million upon the completion of the technology transfer of the Company’s manufacturing process for the COVID-19 Vaccine Products to Sanofi, and up to $350 million in CIC Product-related development and launch milestones.

The Company is also eligible to receive development, launch, and sales milestone payments of up to $200 million for each of the first four Adjuvant Products and $210 million for each Adjuvant Product thereafter, and royalty payments on Sanofi’s sales of all such licensed products. In addition, a portion of the technology transfer costs and research and development costs incurred by the Company will be reimbursed by Sanofi in accordance with agreed upon plans and budgets.

The Company assessed whether the Sanofi CLA fell within the scope of ASC 808, Collaborative Arrangements (“ASC 808”) based on whether the arrangement involved joint operating activities and whether both parties have active participation in the arrangement and are exposed to significant risks and rewards. The Company determined that the Sanofi CLA did not fall within the scope of ASC 808, as the Company does not share in the significant financial risks of Sanofi's development or commercialization activities. The Company then analyzed the arrangement pursuant to the provisions of ASC 606 and determined that the arrangement represents a contract with a customer and is therefore within the scope of ASC 606.

The Company identified the following performance obligations in the Sanofi CLA and determined that they were within the scope of ASC 606: delivery of (i) the licenses described above (the COVID-19 Vaccine license, CIC Products license, Other Combination Product license, and Adjuvant Products license) (collectively the “Sanofi CLA Licenses’), (ii) research and development transition services that support further regulatory approval and development of the COVID-19 Vaccine, referred to as the Sanofi Transition Services, and (iii) technology transfer of the existing manufacturing process for the COVID-19 Vaccine Products and Matrix-M™ adjuvant, referred to as the “Sanofi Technology Transfer”.

The Company also evaluated whether certain options outlined in the Sanofi Agreement represented material rights that would give rise to a performance obligation and concluded that none of the options convey a material right to Sanofi and therefore are not considered separate performance obligations within the Sanofi CLA.

The Sanofi CLA Licenses performance obligations are considered functional intellectual property and distinct from other promises under the contract as Sanofi can benefit from the licenses on their own or together with other readily available resources. Also, the Sanofi Transition Services provide a distinct benefit to Sanofi within the context of the contract, separate from the licenses, as the services could be provided by Sanofi or another third party without the Company’s assistance. The Sanofi Technology Transfer obligation is distinct as Sanofi can benefit from the Sanofi CLA Licenses transferred by the Company at the inception of the agreement with other readily available resources. Therefore, each represents a separate performance obligation within the contract with a customer under the scope of ASC 606 at contract inception.

The Company determined the initial transaction price at inception of the Sanofi CLA to be $620.2 million, consisting of (i) fixed consideration (the $500 million upfront nonrefundable fee), (ii) and $120.2 million of variable consideration attributed to a $50.0 million clinical milestone and $70.2 million of estimated cost reimbursement related to Sanofi Transition Services and Sanofi Technology Transfer. Since the clinical milestone allocated to Sanofi Transition Services is entirely within the Company’s control, and the cost reimbursement variable consideration allocated to Sanofi Transition Services and Sanofi Technology Transfer would be recognized as revenue only as the costs are incurred, the Company determined it is not probable that a significant reversal of cumulative revenue would occur. The Company utilized the expected value method to determine the amount of these payments. The Company excluded certain regulatory and technology transfer milestones from the transaction price that were determined to be inherently uncertain of achievement and are highly susceptible to factors outside of the Company’s control. Sales-based royalties and launch milestones are related to the license of the intellectual property rights and the Company will recognize revenue for these in the period when subsequent sales are made or sale-based milestones are achieved pursuant to the sales-based royalty exception under ASC 606. The Company will re-evaluate the transaction price in each reporting period as uncertain events are resolved or other changes in circumstances occur.

The Company allocated the fixed consideration (i.e., the $500 million nonrefundable upfront fee) to the performance obligations in the Sanofi CLA based on each performance obligation’s relative standalone selling price, or SSP, as follows:

•$386.3 million for the upfront transfer of the licenses;

•$110.2 million for Transition Services; and

•$3.5 million for Technology Transfer.

The SSP for the licenses were determined using an approach that considered discounted, probability-weighted cash flows related to the license transferred. In developing such estimates, the Company applied judgment in determining the forecasted revenues, expected margins, and the discount rate. The SSP for the ongoing Transition Services and Technology Transfer were based on estimates of the associated effort and cost of these services, adjusted for a reasonable gross profit margin that would be expected to be realized under similar contracts.

The Company recognized revenue related to the licenses at a point in time upon transfer of the rights and control of the license to Sanofi during the second quarter 2024. The Sanofi Transition Services and Technology Transfer are recognized in revenue over time using an input method to measure progress by utilizing costs incurred to-date relative to total expected costs. Revenue recognized related to Sanofi Transition Services and Technology Transfer for the three and six month period ended June 30, 2024 was $6.6 million. The Company’s consolidated balance sheet as of June 30, 2024 includes a deferred revenue balance of $109.2 million ($50.9 million included in Deferred revenue, current portion and $58.3 million included in Deferred revenue, non-current portion) related to Transition Services and Technology Transfer.

The Company recognized an asset for $35.0 million of direct costs incurred to obtain the Sanofi CLA. These costs are amortized to expense over the expected period of the benefit in a manner that is consistent with the transfer of the related goods and services in the Sanofi CLA. The Company recognized $27.1 million of amortization expense related to the asset in Selling, general, and administrative expense in the second quarter of 2024.

In May 2024, the Company also entered into the Subscription Agreement, pursuant to which the Company sold and issued to Sanofi, in a private placement, 6,880,481 shares of the Company’s common stock, par value $0.01 per share at a price of $10.00 per share for aggregate gross proceeds to the Company of $68.8 million. The opening price of the Company’s common stock on the date of the sale approximated $10.00 per share and therefore all gross proceeds were allocated to stockholders’ deficit.

Bill & Melinda Gates Medical Research Institute

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

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

Other Supply Agreements

In March 2024, 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 “Settlement Agreement”) to resolve disputes regarding amounts that Fujifilm claimed were due under a prior Confidential Settlement Agreement and Release effective September 30, 2022 (the “CSAR”) by and between the Company and Fujifilm.

Under the CSAR, the Company agreed to pay up to $185.0 million to Fujifilm in connection with the cancellation of manufacturing activity at FDBT. The final two quarterly installments due to Fujifilm in 2023 under the CSAR, totaling $68.6 million, 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. In October 2023, the Company sent Fujifilm a notice of breach and refused to pay the final two installments based on its contention that Fujifilm had not used commercially reasonable efforts to mitigate losses and should have offset some portion of the final two payments. In October 2023, Fujifilm filed a demand for arbitration with Judicial Arbitration and Mediation Services (“JAMS”) seeking payment of the full amount (the “Fujifilm Arbitration”).

Pursuant to the Settlement Agreement, in March 2024, the Company paid $42.0 million to Fujifilm, the parties agreed to a mutual release of claims arising from, under or otherwise in connection with the CSAR, and Fujifilm agreed to dismiss the Fujifilm Arbitration. This payment is less than amounts previously accrued for and reflected in Research and development expense, and accordingly, the Company recorded a benefit of $26.6 million as Research and development expense during the six months ended June 30, 2024 upon the execution of the Settlement Agreement.

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, its COVID-19 Program, and in doing so, recognizes that significant costs may be incurred.

Note 13 – Stock-Based Compensation

Equity Plans

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 30, 2024, there were 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 annual meeting of stockholders in June 2015. Under the 2015 Plan, equity awards may be granted to officers, directors, employees, and consultants of and advisors to the Company and any present or future subsidiary.

The 2015 Plan authorizes the issuance of up to 27.5 million shares of common stock under equity awards granted under the 2015 Plan. All such shares authorized for issuance under the 2015 Plan have been reserved. The 2015 Plan will expire on April 18, 2034. As of June 30, 2024, there were 9.4 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.

The 2023 Inducement Plan and the 2015 Plan permit, and the 2005 Plan permitted, the grant of stock options (including incentive stock options), restricted stock, stock appreciation rights (“SARs”), and restricted stock units (“RSUs”). In addition, under the 2023 Inducement Plan and the 2015 Plan, unrestricted stock, stock units, and performance awards may be granted. Stock options and SARs generally have a maximum term of ten years and may be or were granted with an exercise price that is no less than 100% of the fair market value of the Company’s common stock at the time of grant. Grants of 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):


	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Cost of sales	$	1,104	$	998	$	1,698	$	1,516
Research and development	6,177		9,946		11,682		23,804
Selling, general, and administrative	6,818		9,348		12,275		23,619
Total stock-based compensation expense	$	14,099	$	20,292	$	25,655	$	48,939

During the three and six months ended June 30, 2024 and 2023, there was no stock-based compensation expense capitalized into inventory.

As of June 30, 2024, there was approximately $73 million of total unrecognized compensation expense related to unvested stock options, SARs, RSUs, and the ESPP. This unrecognized non-cash compensation expense is expected to be recognized over a weighted-average period of approximately one year and will be allocated between cost of sales, research and development, and general and administrative expenses accordingly. This estimate does not include the impact of other possible stock-based awards that may be made during future periods.

The aggregate intrinsic value represents the total intrinsic value (the difference between the Company’s closing stock price on the last trading day of the period and the exercise price, multiplied by the number of in-the-money stock options and SARs) that would have been received by the holders had all stock option and SAR holders exercised their stock options and SARs on June 30, 2024. This amount is subject to change based on changes to the closing price of the Company's common stock. The aggregate intrinsic value of stock options and SARs exercises and vesting of RSUs for the six months ended June 30, 2024 and 2023 was approximately $8 million and $2 million, respectively.

The total aggregate intrinsic value and weighted-average remaining contractual term of stock options and SARs outstanding under the 2023 Inducement Plan, 2015 Plan and 2005 Plan as of June 30, 2024 was $12.3 million and 7.0 years, respectively. The total aggregate intrinsic value and weighted-average remaining contractual term of stock options and SARs exercisable under the 2023 Inducement Plan, 2015 Plan and 2005 Plan as of June 30, 2024 was $3.7 million and 6.0 years, respectively.

Employee Stock Purchase Plan

The ESPP was approved at the Company’s annual meeting of stockholders in June 2013. The ESPP currently authorizes an aggregate of 2.2 million shares of common stock to be purchased, and the aggregate number of shares will continue to increase 5% on January 1 of each year up to a maximum of 3.5 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 30, 2024, there were 1.2 million shares available for issuance under the ESPP.

Note 14 – Income Taxes

The Company evaluates the available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit use of the existing deferred tax assets. Significant pieces of objective evidence evaluated by the Company were the cumulative loss incurred over the three-year period ended June 30, 2024 and that the Company has historically generated pretax losses. Such objective evidence limits the ability to consider other subjective evidence, such as projections for future growth. On the basis of this evaluation, as of June 30, 2024, 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. As of June 30, 2024, the Company has $2.3 billion of U.S. Federal NOLs carryforward, and all 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.

For the three months ended June 30, 2024 and 2023, the Company recognized $2.2 million and $(0.1) million of federal, state, and foreign income tax expense (benefit), respectively. During the six months ended June 30, 2024 and 2023, the Company recognized $4.5 million and $1.0 million of federal, state, and foreign income tax expense, respectively.

Note 15 – Commitments and Contingencies

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 prototype vaccine on a commercial scale and to secure the 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. On December 4, 2023, the parties agreed to a binding settlement in principle (the “Proposed Settlement”) to fully resolve the surviving claims in the Sinnathurai Action. Under the Proposed Settlement’s terms, the Company agreed to pay $47 million into a settlement fund, which will be funded by the Company’s directors and officers’ liability insurance and paid to members of a putative settlement class. On January 12, 2024, after the parties negotiated and executed a written agreement governing the Proposed Settlement, plaintiffs filed an unopposed motion for the Proposed Settlement’s preliminary approval. On January 23, 2024, the Maryland Court granted the motion for preliminary approval and, as requested by the parties, preliminarily certified, for the purposes of settlement only, the settlement class. The court also scheduled a settlement hearing to consider final approval of the settlement for May 23, 2024. Ahead of the May 23 settlement hearing, on April 11, 2024, Plaintiffs filed a motion seeking the Maryland Court’s final approval of the settlement. At the May 23 settlement hearing, the Maryland Court granted final approval of the settlement. The Maryland Court closed the Sinnathurai Action on May 24, 2024. Upon the Maryland Court’s final approval, the Company relieved the $47 million estimated settlement liability within Accrued expenses and the $47 million estimated insurance recovery within Prepaid expenses and other current assets on the consolidated balance sheet.

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. Stanley C. Erck, et al., No. 2022-0770-NAC (the “Mesa Action”), (vii) Sean Acosta v. Stanley C. Erck, et al., No. 2022-1133-NAC (the “Acosta Action”), and (viii) Jared Needelman v. Stanley C. 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 May 10, 2022, the Maryland Court entered an order granting the parties’ request to stay all proceedings and deadlines pending the earlier of dismissal or the filing of an answer in the Sinnathurai Action. On June 10, 2022, the Snyder and Blackburn Actions were filed. On October 5, 2022, the Maryland Court entered an order granting a request by the plaintiffs in the First Consolidated Derivative Action and the Snyder and Blackburn Actions to consolidate all three actions and appoint co-lead plaintiffs and co-lead and liaison counsel (the “Second Consolidated Derivative Action”). The co-lead plaintiffs in the Second Consolidated Derivative Action filed a consolidated amended complaint on November 21, 2022. On February 10, 2023, defendants filed a motion to dismiss the Second Consolidated Derivative Action. The plaintiffs filed their opposition to the motion to dismiss on April 11, 2023. Defendants filed their reply brief in further support of their motion to dismiss on May 11, 2023. On August 21, 2023, the court entered an order granting in part and denying in part the motion to dismiss. On September 5, 2023, the Company filed an Answer to the consolidated amended complaint. On September 6, 2023, the court entered an order granting the individual defendants an extension of time to file their answer until November 6, 2023. 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, and, on April 15, 2024, the court entered a further order extending the stay until June 6, 2024. On June 7, 2024, the court entered another order extending the stay until August 5, 2024. This includes staying the deadline for the individual defendants to respond to the consolidated amended complaint. On August 5, 2024, the parties agreed to a further 90-day extension to November 4, 2024, which remains subject to court approval.

The Kirst Action was filed on December 28, 2021, and the defendants immediately removed the case to the Maryland Court. On July 21, 2022, the Maryland Court issued a memorandum opinion and order remanding the Kirst Action to state court. 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 the parties’ stipulated stay of the Kirst Action pending resolution of the motion to dismiss in 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. On January 9, 2023, following the ruling on the motion to dismiss the Sinnathurai Action, the Delaware Court entered an order granting the Mesa Action parties’ request to set a briefing schedule in connection with a motion to stay by defendants. On February 28, 2023, the court granted the defendants’ motion and stayed the Mesa Action pending the entry of a final, non-appealable judgment in the Second Consolidated Derivative Action. On August 31, 2023, the Mesa plaintiffs filed a motion to lift the stay in the Mesa Action. On October 6, 2023, the Company filed an opposition to plaintiff’s motion to lift the stay. Plaintiff filed his reply on October 17, 2023. On December 27, 2023, the parties filed a letter informing the Court that the Second Consolidated Derivative Action had been stayed for a period of six months and asked the Court to stay further proceedings in the Mesa Action until expiration of that stay.

On December 7, 2022, the Acosta Action was filed. On February 6, 2023, defendants accepted service of the complaint and summons in the Acosta Action. On March 9, 2023, the court entered an order granting the parties’ request to stay the Acosta Action pending the entry of a final, non-appealable judgment in the Second Consolidated Derivative Action. On October 13, 2023, the parties filed, and the Delaware Court entered, a stipulated order providing that (i) if the Delaware Court declines to lift the stay in the Mesa Action, the Acosta Action will also remain stayed, and (ii) if the Delaware Court lifts the stay in the Mesa Action, the stay in the Acosta Action will also be lifted.

On April 17, 2023, the Needelman Action was filed. On July 12, 2023, the parties filed a stipulation and proposed order to stay the Needelman Action pending the Maryland Court’s decision on the motion to dismiss in the Second Consolidated Derivative Action. The court entered that order on July 17, 2023.

On November 30, 2023, the court entered an order consolidating the Kirst and Needelman Actions.

Note 16 – Restructuring

In May 2023, the Company announced a global restructuring and cost reduction plan (the “2023 Restructuring Plan”), which includes a more focused investment in its COVID-19 Vaccine, 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. In January 2024, the Company announced further reductions to its global workforce which supplemented the 2023 Restructuring Plan and both are jointly referred to as the “Restructuring Plan.”

The Company recorded the following restructuring charge related to the Restructuring Plan in the consolidated statements of operations (in thousands):


	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Severance and employee benefit costs	$	1,119	$	4,643	$	5,520	$	4,643


Impairment of assets	—		10,081		1,669		10,081


Total Restructuring charge (1)	$	1,119	$	14,724	$	7,189	$	14,724

(1) Restructuring charges of $0.5 million, $0.3 million and $0.3 million are included in Cost of sales, Research and development and Selling, general, and administrative expenses, respectively, in the Consolidated Statements of Operations for the three months ended June 30, 2024. Restructuring charges of $0.5 million, $1.9 million and $4.8 million are included in Cost of sales, Research and development and Selling, general, and administrative expenses, respectively, in the Consolidated Statements of Operations for the six months ended June 30, 2024. Restructuring charges of $0.5 million, $2.7 million and $11.5 million are included in Cost of sales, Research and development and Selling, general, and administrative expenses, respectively, in the Consolidated Statements of Operations for the three and six months ended June 30, 2023.

Severance and employee benefit costs

Employees affected by the reduction in force under the Restructuring Plan are entitled to receive severance payments and certain termination benefits. The Company recorded a severance and termination benefit cost in full for employees who were notified of their termination during the reporting period and had no requirements for future service. The Company paid a total of $5.5 million for the severance and employee benefit costs during the six months ended June 30, 2024 and had no remaining liability as of June 30, 2024 or December 31, 2023.

Impairment of assets

In connection with the Restructuring Plan, the Company evaluated its long-lived assets for impairment including certain leased laboratory and office spaces located in Gaithersburg, Maryland. The Company performed an impairment evaluation for the applicable long-lived assets, which is subject to judgment and actual results may vary from the estimates, resulting in potential future adjustments to amounts recorded. During the six months ended June 30, 2024, the Company recorded an impairment charge of $1.7 million related to the impairment of capitalized internal-use software. During the three and six months ended June 30, 2023, the Company recorded an impairment charge of $10.1 million related to the impairment of

long-lived assets, including $5.9 million related to ROU assets for facility leases. The Company did not recognize any impairment of assets related restructuring charges during the three months ended June 30, 2024.

Overview

We are a global company advancing protein-based vaccines with our Matrix-MTM adjuvant. Our proprietary recombinant technology platform harnesses the power and speed of genetic engineering to efficiently produce highly immunogenic nanoparticle vaccines designed to address global health needs.

Our vaccine candidates are nanostructures of conformationally correct recombinant proteins that mimic those found on pathogens. This technology enables the immune system to recognize target proteins and develop protective 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 an updated vaccine for individuals aged 12 and older for the upcoming 2024-2025 vaccination season and are seeking authorization of our updated vaccine globally. We submitted an amendment to our previously granted October 2023 Emergency Use Authorization (“EUA”) to the U.S. FDA, filed for a type II variation of our existing Marketing Authorization (“MA”) with the European Medicines Agency (“EMA”), and the United Kingdom's (“UK”) Medicines and Healthcare products Regulatory Agency (“MHRA”), and filed for authorization with Health Canada. These submissions follow the guidance from the U.S. FDA, EMA, the World Health Organization (“WHO”), and the National Advisory Committee on Immunization on the use of the JN.1 lineage strain for the updated formulation. We intend to ship our updated vaccine upon authorization in these markets.

In the U.S., we were notified by the U.S. FDA that our BLA for our prototype vaccine and for NVX-CoV2601 was accepted for review with an action date of April 2025.

In May 2024, we entered into the Sanofi CLA with Sanofi, to co-commercialize our COVID-19 Vaccine, including future updated versions that address seasonal COVID-19 variants. We will continue commercialization of our updated vaccine. Beginning in 2025 and continuing during the term of the Sanofi CLA, we and Sanofi will commercialize the COVID-19 Vaccine worldwide in accordance with a commercialization plan agreed by us and Sanofi, under which we will continue to supply its existing APA customers and strategic partners, including Takeda and SII. Upon completion of the existing APAs, we and Sanofi will jointly agree on commercialization activities of each party in each jurisdiction. Additionally, Sanofi has the right to develop novel influenza-COVID-19 combination vaccines utilizing our COVID-19 Vaccine and Sanofi’s seasonal influenza vaccine, combination products containing our COVID-19 Vaccine and one or more non-influenza vaccines, and multiple new vaccines utilizing our Matrix-MTM adjuvant. We are eligible to receive royalties and milestones associated with the ongoing sales of our COVID-19 Vaccine and Sanofi’s influenza-COVID-19 combination vaccine and any other combination vaccines Sanofi may develop, as well as ongoing product royalties for vaccines developed with our Matrix-MTM adjuvant. This partnership provides the opportunity for us to focus more on research and development and pipeline expansion. We discuss this agreement in further detail in Note 6 to our consolidated financial statements.

Additionally, our near-term focus is on developing a CIC vaccine candidate, as well as a stand-alone seasonal influenza vaccine candidate, and we are on track to initiate a Phase 3 trial in the fourth quarter of 2024 for both vaccine candidates. Furthermore, we provide our Matrix-M™ adjuvant for collaborations, including in R21/Matrix-M™ adjuvant malaria vaccine, which is authorized in several countries, as well as other preclinical vaccine research with our Matrix-M™ adjuvant, including through a partnership with the Bill & Melinda Gates Medical Research Institute.

We intend to focus our organization to align our investments and activities with our top priorities of prioritizing the successful transition to our new partnership with Sanofi, executing our Phase 3 programs for the CIC and stand-alone seasonal influenza vaccine candidates, and delivering our updated vaccine. 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 the best position for us to deliver longer-term growth. We discuss these cost restructuring strategies in greater detail in Note 2 to our consolidated financial statements.

Technology Overview

We believe our recombinant nanoparticle vaccine technology and our proprietary Matrix-M™ adjuvant are 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 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 SII for commercialization, and in December 2023, received prequalification by the WHO. In July 2024, first commercial doses of the R21/Matrix-M™ adjuvant malaria vaccine were administered to children in Cote d’Ivoire and South Sudan. Additionally, in May 2023, we entered into a three-

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. In May 2024, pursuant to the Sanofi CLA, Sanofi received a non-exclusive license to develop and commercialize other vaccine products that include our Matrix-M™ adjuvant.

COVID-19 Vaccine Regulatory and Licensure

For our updated vaccine for the 2024-2025 vaccination season, we submitted an amendment to our previously granted October 2023 EUA to the U.S. FDA, filed for a type II variation of our existing MA with the EMA, and the UK’s MHRA, and filed for authorization with Health Canada.

If the U.S. FDA grants an amended EUA for our updated vaccine, we expect that initial stocking orders of our updated vaccine will be available for shipment in pre-filled syringes to customers. In the European Union, we intend to have our updated vaccine available for distribution in unit-dose vials for immediate release post-approval. Additionally, in the U.K., we intend to have our updated vaccine available on the private market and in Canada, in five-dose vials for immediate release post-authorization should Canadian public health programs choose to provide the option for five-dose vials.

We are working to continue to expand our label 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.

Product Pipeline

Our clinical pipeline encompasses vaccine candidates for infectious diseases. Our COVID-19 vaccine, partnered with Sanofi, is our most advanced product. We are seeking authorization of our 2024-2025 formulated JN.1 COVID vaccine globally. We will continue to commercialize our JN.1 COVID vaccine through the end of the 2024-2025 vaccination season. Beyond our COVID-19 vaccine, our clinical pipeline includes a CIC vaccine candidate and a stand-alone seasonal influenza vaccine candidate in addition to our Matrix-M™ adjuvant being used for collaboration in R21/Matrix-M™ adjuvant malaria vaccine.

Novavax continues to optimize preclinical candidates, including an RSV vaccine and a new approach to H5N1 pandemic bird flu vaccination. In addition, we are seeking to expand our core technology to new targets and novel applications including mucosal vaccination and high-density nanoparticles. We continue to evaluate the potential of Matrix-M™ to augment immune responses to new and existing vaccines, including marketed products. We are conducting a prioritization review of our preclinical candidates to inform future early-stage clinical study investments to advance Novavax’s product pipeline.

(1) Authorized in select geographies under trade names Novavax COVID-19 Vaccine, Adjuvanted; Covovax™; and Nuvaxovid™, and authorized in the U.S. under trade name, Novavax COVID-19 Vaccine, Adjuvanted (2023-2024 Formula); Ongoing post-authorization Phase 3 strain change trial.

(2) Commercialized by SII; Granted prequalification by the WHO and distributed by UNICEF to endemic countries in Africa.

Coronavirus Vaccine Clinical Development

We continue to work on our efforts to expand our COVID-19 vaccine label within the adolescent and pediatric indications. Additionally, we continue to evaluate vaccine safety, immunogenicity, and effectiveness through ongoing clinical trials and collaborative evidence-generating real-world studies.

Phase 3 Strain-Change and Re-vaccination Studies

Study 313: In November 2023, we fully enrolled 338 adults aged 18 and older in Part 2 of the study which will evaluate the immunogenicity of a single dose of NVX-CoV2601 in previously unvaccinated individuals. Data from Study 313 are intended to support BLA supplements and similar regulatory submissions in other territories for future variant strain formulations.

Phase 2b/3 Pediatric Hummingbird™ 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 demonstrating both tolerability and immunologic responses. This ongoing trial is evaluating the safety, effectiveness (immunogenicity), and efficacy of two doses of our prototype vaccine (NVX-CoV2373), followed by a booster 6 months after the primary vaccination series. The trial completed enrollment in September 2023 and includes three age de-escalation cohorts of 1,200 children each. In consultation with the U.S. FDA, the filing strategy includes filing a supplemental BLA for these cohorts once the initial BLA is approved. We are in discussion with the U.S. FDA regarding additional analyses in light of the progressive increase in the number of children with baseline COVID-19 natural immunity during the enrollment period, which began in August 2022. Therefore, we do not anticipate authorization for these age groups for the 2024-2025 vaccination season.

COVID-Influenza Combination and Stand-alone Influenza Program

For our CIC vaccine candidate, we continue to interact with the U.S. FDA as part of the pre-investigational new drug application (“IND”) process and incorporate their recommendations into the Phase 3 design, study endpoints, comparators, and size of licensure enabling safety database. We previously disclosed our plan to modify the study to include a stand-alone influenza vaccine comparative component. We remain on track to initiate the study in the fourth quarter of 2024.

While our focus remains on the combination product, our development plans will maintain optionality to advance our stand-alone seasonal influenza vaccine, as described above, creating a pathway to potentially seek licensure. For our stand-alone seasonal influenza vaccine, we have generated positive data through our previous Phase 2 and Phase 3 trials. We expect to confirm and expand on these findings in the newly planned Phase 3 trial. We continue to believe this asset may also be attractive from a pandemic preparedness perspective and that similar performance in terms of comparative immunogenicity may be expected for A/H5N1 pandemic strains.

High-dose COVID-19 Vaccine Study

Study 205: In October 2023, we completed enrollment in a Phase 2 trial to evaluate our high-dose COVID-19 vaccine for annual vaccination in 994 adults ages 50 years and older. The trial measured immunogenicity levels of 5 micrograms of NVX-CoV2373 and of 5 micrograms, 35 micrograms, and 50 micrograms of NVX-CoV2601 matched with different levels of Matrix-MTM adjuvant. Analysis of the complete dataset is ongoing to determine the utility of pursuing a high dose formulation.

R21/Matrix-M™ Adjuvant Malaria Vaccine

R21/Matrix-M™ adjuvant malaria vaccine, formulated with our Matrix-M™ adjuvant is developed by our partner, the Jenner Institute, University of Oxford, and manufactured by SII. We have an agreement with SII related to its manufacture of R21/Matrix-M™ adjuvant malaria vaccine under which SII purchases our Matrix-M™ adjuvant for use in development activities at cost and for commercial purposes at a tiered commercial supply price, and pays 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 December 2023, the WHO announced it prequalified the R21/Matrix-MTM adjuvant malaria vaccine to prevent malaria disease in children caused by the P. falciparum parasite in endemic areas. In July 2024, first commercial doses of R21/Matrix-M™ adjuvant malaria vaccine have been administered to children in Cote d’Ivoire and South Sudan. As part of the WHO malaria program, at their discretion, the vaccine is expected to be included in countries such as Central African Republic, Chad, Democratic Republic of Congo, Mozambique, Nigeria and Uganda.

Sales of Common Stock

In August 2023, we entered into an At Market Issuance Sales Agreement (the “August 2023 Sales Agreement”), which allows us to issue and sell up to $500 million in gross proceeds of shares of its common stock, and terminated our then-existing At Market Issuance Sales agreement entered in June 2021 (the “June 2021 Sales Agreement”). During the three and six months ended June 30, 2024, we sold 12.2 million shares of our common stock resulting in net proceeds of approximately $188 million,

under the August 2023 Sales Agreement. As of June 30, 2024, the remaining balance available under the August 2023 Sales Agreement was approximately $51 million.

During the three and six months ended June 30, 2023, we sold 7.9 million shares of our common stock under our June 2021 Sales Agreement resulting in net proceeds of approximately $68 million, of which $6.0 million was included in prepaid expenses and other current assets as of June 30, 2023 and received in cash in July 2023.

In May 2024, we also entered into a securities subscription agreement (the “Subscription Agreement”) with Sanofi, pursuant to which we sold and issued to Sanofi, in a private placement, 6,880,481 shares of our common stock, par value $0.01 per share at a price of $10.00 per share for aggregate gross proceeds to us of $68.8 million. The opening price of our common stock on the date of the sale approximated $10.00 per share and therefore all gross proceeds were allocated to stockholders’ deficit.

Critical Accounting Policies and Use of Estimates

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

The preparation of our consolidated financial statements requires us to make estimates, assumptions, and judgments that affect the reported amounts of assets, liabilities, and equity and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Our critical accounting policies and estimates are included under Item 7 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, as filed with the SEC and are updated below to incorporate revenue recognition from licensing and transition services included in Licensing, royalties and other in our consolidated financial statements.

Revenue Recognition, Licensing and Transition Services

The terms of licensing agreements may contain multiple performance obligations, which may include licenses and transition services. We evaluate licensing agreements under ASC 606, Revenue from Contracts with Customers (“ASC 606”), to determine the distinct performance obligations. Prior to recognizing revenue, we estimate the transaction price, including variable consideration that is subject to a constraint. Variable consideration is included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur and when the uncertainty associated with the variable consideration is subsequently resolved. Total consideration may include nonrefundable upfront license fees, transition service fees, other payments based upon the achievement of specified milestones, and royalty payments based on product sales from licensed products.

For multiple distinct performance obligation arrangements, we allocate the transaction price to each distinct performance obligation based on its relative standalone selling price. The standalone selling price is generally determined for each performance obligation based on the prices charged to customers, discounted cash flows, or using expected cost-plus margin. For standalone selling prices determined using discounted cash flows, we consider discounted, probability-weighted cash flows related to the performance obligation transferred. In developing such estimates, we apply judgment in determining the forecasted revenues, expected margins, and the discount rate. These estimates are subjective and require us any to make assumptions about future cash flows. Revenue related to performance obligations satisfied at a point in time is recognized when the customer obtains control of the promised asset. For performance obligations recognized over time, we recognize revenue using an input method to measure progress by utilizing costs incurred to-date relative to total expected costs. Under this process, we consider the costs that have been incurred to-date, as well as projections to completion using various inputs and assumptions, including, but not limited to, progress towards completion, labor costs and level of effort, material and subcontractor costs, indirect administrative costs, and other identified risks. Estimating the total cost at completion of our performance obligation under a contract is subjective and requires us to make assumptions about future activity and cost drivers. Changes in these estimates can occur for a variety of reasons and may impact the timing of revenue recognition on our contracts. Changes in estimates related to the process are recognized in the period when such changes are made on a cumulative catch-up basis. We have not experienced any material difference as a result of change in estimate arising from this process.

Results of Operations

The following is a discussion of the historical financial condition and results of our operations that should be read in conjunction with the unaudited consolidated financial statements and notes set forth in this Quarterly Report.

Three Months Ended June 30, 2024 and 2023

Revenue


	Three Months Ended June 30,
	2024		2023		Change
Revenue (in thousands):
Product sales	$	19,904	$	285,163	$	(265,259)
Licensing, royalties, and other	395,580		2,184		393,396
Grants	—		137,079		(137,079)
Total revenue	$	415,484	$	424,426	$	(8,942)

Revenue for the three months ended June 30, 2024 was $415.5 million as compared to $424.4 million for the same period in 2023, an decrease of $8.9 million. Revenue for the three months ended June 30, 2024 was primarily comprised of revenue from licensing and revenue from product sales of COVID-19 Vaccine. Revenue for the three months ended June 30, 2023 was primarily comprised of product sales of COVID-19 Vaccine and services performed under our U.S. government agreement with Advanced Technology International (“USG Agreement”), the Consortium Management Firm acting on behalf of the Medical CBRN Defense Consortium in connection with the partnership formerly known as Operation Warp Speed. The decrease in revenue is due to a decrease in the quantity of dose sales of COVID-19 Vaccine and a decrease in revenue under the USG Agreement during the three months ended June 30, 2024 because we recognized the full funding in revenue by the end of 2023, partially offset by additional licensing revenue from the Sanofi Collaboration and Licensing Agreement (“Sanofi CLA”).

Product sales

Product sales for the three months ended June 30, 2024 were $19.9 million as compared to $285.2 million during the three months ended June 30, 2023. Our product sales related to revenue from commercial sales of COVID-19 Vaccine, which commenced in 2022.

The geographic distribution of product sales was as follows:


	Three Months Ended June 30,
	2024		2023		Change
North America	$	1,607	$	—	$	1,607
Europe	169		1,518		(1,349)
Rest of the world	18,128		283,645		(265,517)
Total product sales	$	19,904	$	285,163	$	(265,259)

Licensing, royalties, and other

Licensing, royalties, and other includes licensing payments, Transition Services revenue, and Technology Transfer revenue from the Sanofi CLA; royalty milestone payments; sales-based royalties; and Matrix-M™ adjuvant sales. Licensing, royalties, and other revenue during the three months ended June 30, 2024 was $395.6 million as compared to $2.2 million during the same period in 2023, an increase of $393.4 million. The increase was primarily due to $386.3 million of licensing revenue from the Sanofi CLA, which represents the amount of the $500 million upfront payment recognized at a point-in-time. The remaining amount of the upfront payment will be recognized in revenue as Transition Services and Technology Transfer are performed over time. During the three months ended June 30, 2024, we recognized $6.6 million based on progress completed of Transition Services.

Grants

We did not have any Grant revenue during the three months ended June 30, 2024, as compared to $137.1 million during the same period in 2023, a decrease of $137.1 million. Grant revenue comprised revenue for services performed under our USG Agreement. As of December 31, 2023, we had recognized the full contract funding under the USG Agreement in revenue.

Expenses


	Three Months Ended June 30,
	2024		2023		Change
Expenses (in thousands):
Cost of sales	$	46,242	$	55,777	$	(9,535)
Research and development	106,946		219,475		(112,529)
Selling, general, and administrative	101,298		93,717		7,581
Total expenses	$	254,486	$	368,969	$	(114,483)

Cost of Sales

Cost of sales was $46.2 million for the three months ended June 30, 2024, including expenses of $11.4 million related to excess, obsolete, or expired inventory and losses on certain firm purchase commitments, and $12.9 million related to unutilized manufacturing capacity. Cost of sales was $55.8 million for the three months ended June 30, 2023, including expense of $19.8 million related to excess, obsolete, or expired inventory and losses on firm purchase commitments, partially offset by $17.9 million of negotiated reductions to certain previously recognized firm purchase commitments, and $11.4 million related to unutilized manufacturing capacity. 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. During the three months ended June 30, 2024, we did not sell any pre-launch inventory. If inventory sold for the three months ended June 30, 2023 was valued at expected standard cost, adjusted cost of sales for the period would have been approximately $71.7 million, an adjustment of $15.9 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 $106.9 million for the three months ended June 30, 2024 as compared to $219.5 million for the three months ended June 30, 2023, a decrease of $112.5 million. The decrease was primarily due to a reduction in overall expenditures relating to development activities on coronavirus vaccines, including our COVID-19 Program, and CIC, as summarized in the table below (in thousands):


	Three Months Ended June 30,
	2024		2023
Coronavirus vaccines	$	40,812	$	139,646
Other vaccine development programs	400		285
Total direct external research and development expense	41,212		139,931
Employee expenses	36,238		46,132
Stock-based compensation expense	6,158		9,946
Facility expenses	12,914		14,158
Other expenses	10,424		9,308
Total research and development expenses	$	106,946	$	219,475

Research and development expenses for coronavirus vaccines for the three months ended June 30, 2024 and 2023 decreased from $139.6 million to $40.8 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”).

Selling, General, and Administrative Expenses

Selling, general, and administrative expenses were $101.3 million for the three months ended June 30, 2024 as compared to $93.7 million for the same period in 2023, an increase of $7.6 million. Excluding the Sanofi transaction related costs of $29.5 million, the decrease in selling, general, and administrative expenses is primarily due to certain cost containment measures to reduce our operating spend.

For the remainder of 2024, we expect a reduction in our annual combined research and development, and selling, general, and administrative spend as a result of our Restructuring Plan as discussed in Note 16 to our consolidated financial statements.

Other Income (Expense)


	Three Months Ended June 30,
	2024		2023		Change
Other income, net (in thousands):
Interest expense	$	(4,143)	$	(3,124)	$	(1,019)
Other income	7,731		5,532		2,199
Total other income, net	$	3,588	$	2,408	$	1,180

Total other income, net was $3.6 million for the three months ended June 30, 2024 as compared to a total other income, net of $2.4 million for the same period in 2023. The increase in other income, net is primarily due to additional interest income from higher Cash and cash equivalents and Marketable securities balances.

Income Tax Expense

During the three months ended June 30, 2024, we recognized an income tax expense of $2.2 million related to federal, state, and foreign income taxes. During the three months ended June 30, 2023, we recognized an income tax benefit of $0.1 million related to federal, state, and foreign income taxes.

Net Income


	Three Months Ended June 30,
	2024		2023		Change
Net Income (in thousands, except per share information):
Net income	$	162,381	$	58,008	$	104,373
Net income per share, basic	$	1.09	$	0.65	$	0.44
Net income per share, dilutive	$	0.99	$	0.58	$	0.41
Weighted average shares outstanding, basic	148,379		89,362		59,017
Weighted average shares outstanding, dilutive	165,855		104,065		61,790

Net income for the three months ended June 30, 2024 was $162.4 million, or $1.09 per share, basic, as compared to net income of $58.0 million, or $0.65 per share, basic, for the same period in 2023. The increase in net income during the three months ended June 30, 2024, was primarily due to a decrease in research and development expenses.

The increase in weighted average shares outstanding for the three months ended June 30, 2024 was primarily a result of sales of our common stock.

Six Months Ended June 30, 2024 and 2023

Revenue


	Six Months Ended June 30,
	2024		2023		Change
Revenue (in thousands):
Product sales	$	102,228	$	277,706	$	(175,478)
Licensing, royalties, and other	407,111		3,213		403,898
Grants	—		224,458		(224,458)
Total revenue	$	509,339	$	505,377	$	3,962

Revenue for the six months ended June 30, 2024 was $509.3 million as compared to $505.4 million for the same period in 2023, an increase of $4.0 million. Revenue for the six months ended June 30, 2024 was primarily comprised of revenue from licensing and product sales of COVID-19 Vaccine. Revenue for the six months ended June 30, 2023 was primarily comprised of revenue from product sales of COVID-19 Vaccine and services performed under our USG Agreement. The increase in revenue is due to $392.9 million of licensing and other revenue from the Sanofi CLA, partially offset by a decrease in revenue under the USG Agreement and in the quantity of dose sales of COVID-19 Vaccine.

Product sales

Product sales for the six months ended June 30, 2024 were $102.2 million as compared to $277.7 million during the six months ended June 30, 2023. Our product sales related to revenue from commercial sales of COVID-19 Vaccine, which commenced in 2022. Our product sales primarily related to sales of COVID-19 Vaccine under our APA agreements.

The geographic distribution of product sales was as follows:


	Six Months Ended June 30,
	2024		2023		Change
North America	$	(4,755)	$	—	$	(4,755)
Europe	90,586		58,785		31,801
Rest of the world	16,397		218,921		(202,524)
Total product sales	$	102,228	$	277,706	$	(175,478)

During the six months ended June 30, 2024, product sales in North America includes $4.8 million of gross-to-net deductions in excess of the wholesaler acquisition costs (“WAC”), primarily due to wholesale distributor fees for shipments expected to be returned and adjustments made to estimated returns of prior period product sales.

Licensing, royalties, and other

Licensing, royalties, and other includes licensing payments, Transition Services revenue, and Technology Transfer revenue from the Sanofi CLA; royalty milestone payments; sales-based royalties; and Matrix-M™ adjuvant sales. Licensing, royalties, and other revenue during the six months ended June 30, 2024 was $407.1 million as compared to $3.2 million during the same period in 2023, an increase of $403.9 million. The increase was primarily due to $386.3 million of licensing revenue from the Sanofi CLA, which represents the amount of the $500 million upfront payment recognized at a point-in-time. The remaining amount of the upfront payment will be recognized in revenue as Transition Services and Technology Transfer are performed over time. During the six months ended June 30, 2024, we recognized $6.6 million based on progress completed of Transition Services.

Grants

We did not have any Grant revenue during the six months ended June 30, 2024 as compared to $224.5 million during the same period in 2023, a decrease of $224.5 million. Grant revenue comprised revenue for services performed under our USG Agreement. As of December 31, 2023, we had recognized the full contract funding under the USG Agreement in revenue.

Expenses


	Six Months Ended June 30,
	2024		2023		Change
Expenses (in thousands):
Cost of sales	$	105,451	$	89,863	$	15,588
Research and development	199,625		466,576		(266,951)
Selling, general, and administrative	188,096		206,249		(18,153)
Total expenses	$	493,172	$	762,688	$	(269,516)

Cost of Sales

Cost of sales was $105.5 million for the six months ended June 30, 2024, including expenses of $20.2 million related to excess, obsolete, or expired inventory and losses on certain firm purchase commitments, and $18.8 million related to unutilized manufacturing capacity. Cost of sales was $89.9 million for the six months ended June 30, 2023, including expense of $40.0 million related to excess, obsolete, or expired inventory and losses on firm purchase commitments, and a credit of $18.8 million related to negotiated reductions to certain previously recognized firm purchase commitments, and $15.9 million related to unutilized manufacturing capacity. 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. If inventory sold for the six months ended June 30, 2024 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 $107.1 million, an adjustment of $1.6 million as compared to cost of sales recognized. If inventory sold for the six months ended June 30, 2023 was valued at expected standard cost, adjusted cost of sales for the period would have been approximately $120.8 million, an adjustment of $30.9 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 decreased to $199.6 million for the six months ended June 30, 2024 from $466.6 million for the same period in 2023, a decrease of $267.0 million. The decrease was primarily due to a reduction in overall expenditures relating to development activities on coronavirus vaccines, including our COVID-19 Program, and CIC, as summarized in the table below (in thousands):


	Six Months Ended June 30,
	2024		2023
Coronavirus vaccines	$	65,962	$	279,869
Other vaccine development programs	736		2,033
Total direct external research and development expense	66,698		281,902
Employee expenses	74,191		99,545
Stock-based compensation expense	11,663		23,804
Facility expenses	24,696		33,561
Other expenses	22,377		27,764
Total research and development expenses	$	199,625	$	466,576

Research and development expenses for coronavirus vaccines for the six months ended June 30, 2024 and 2023 decreased from $279.9 million to $66.0 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 CMOs and CDMOs. The decrease was also due to a benefit of $26.6 million for the six months ended June 30, 2024 resulting from the Confidential Settlement Agreement and Release agreement entered into with Fujifilm resulting in a reduction to previously recorded expense (see Note 6 to our consolidated financial statements).

Selling, General, and Administrative Expenses

Selling, general, and administrative expenses decreased to $188.1 million for the six months ended June 30, 2024 from $206.2 million for the same period in 2023, a decrease of $18.2 million. Excluding the Sanofi transaction related costs of $30.8 million, the decrease in selling, general, and administrative expenses is primarily due to certain cost containment measures to reduce our operating spend.

Other Income

	2024		2023		Change
Other income, net (in thousands):

Interest expense	$	(8,254)	$	(7,440)	$	(814)
Other income	11,385		29,894		(18,509)
Total other income, net	$	3,131	$	22,454	$	(19,323)

Total other income, net for the six months ended June 30, 2024 was $3.1 million as compared to $22.5 million for the same period in 2023. This is primarily due to a decrease in Other income as a result of the unfavorable impact in 2024 as compared to 2023 of exchange rates on foreign currency denominated balances, including an intercompany loan with Novavax CZ.

Income Tax Expense

During the six months ended June 30, 2024, we recognized an income tax expense of $4.5 million related to federal, state, and foreign income taxes. During the six months ended June 30, 2023, we recognized an income tax expense of $1.0 million related to federal, state, and foreign income taxes.

Net income for the six months ended June 30, 2024 was $14.8 million, or $0.10 per share, basic, as compared to Net loss of $235.9 million, or $2.69 per share, basic, for the same period in 2023. The increase in net income during the six months ended June 30, 2024, was primarily due to a decrease in research and development expenses.

The increase in weighted average shares outstanding for the six months ended June 30, 2024 is primarily a result of sales of our common stock.

Liquidity Matters and Capital Resources

Our future capital requirements depend on numerous factors including, but not limited to, revenue from our product sales, milestone payments, royalties and reimbursements under licensing arrangements with our strategic partners; our projected activities related to the development and commercial support of our COVID-19 Vaccine and our CIC vaccine candidate, including significant commitments under various clinical research organizations, 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 potential combination vaccines candidates, which are in various stages of development. Our ability to generate revenue from product sales is subject

to uncertainty specifically as it relates to our ability to successfully develop, manufacture, distribute, and market our updated vaccine and to successfully execute on our APAs, as discussed below. Additionally, our plans include our ongoing restructuring and cost reduction measures (see Note 16 to the consolidated financial statements), and may also include raising additional capital through a combination of additional equity and debt financing, 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. 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.

In May 2024, we entered into the Sanofi CLA pursuant to which Sanofi received:

i) A co-exclusive license to commercialize our current stand-alone COVID-19 Vaccine, including our prototype vaccine and updated vaccines, that address seasonal variants throughout the world (the “COVID-19 Vaccine Products”);

ii) A sole license to develop and commercialize combination products containing a potential combination of our COVID-19 Vaccine and Sanofi’s seasonal influenza vaccine (“COVID-19 and influenza Combination Products” or “CIC Products”);

iii) A non-exclusive license to develop and commercialize combination products containing both our COVID-19 Vaccine and one or more non-influenza vaccines (“Other Combination Products” and together with the COVID-19 Vaccine Products, CIC Products, and Other Combination Products (“Licensed COVID-19 Products” ); and

iv) A non-exclusive license to develop and commercialize other vaccine products selected by Sanofi that include our Matrix-M™ adjuvant.

Under the Sanofi CLA, we received a non-refundable upfront payment of $500 million. In addition, we will also be eligible to receive development, technology transfer, launch, and sales milestone payments totaling up to $700 million in the aggregate with respect to the Licensed COVID-19 Products and royalty payments on Sanofi’s sales of such licensed products. In addition, we are eligible to receive development, launch, and sales milestone payments of up to $200 million for each of the first four Adjuvant Products and $210 million for each Adjuvant Product thereafter, and royalty payments on Sanofi’s sales of all such licensed products.

Commencing shortly after the effective date of the Sanofi CLA, we commenced activities related to the technology transfer of our manufacturing process for the COVID-19 Vaccine Products and Matrix-M™ components to Sanofi. Until the successful completion of such transfer, we will supply Sanofi with both COVID-19 Vaccine Products and Matrix-M™ intermediary components for Sanofi’s use and are eligible for reimbursement of such costs from Sanofi. Additionally, Sanofi will reimburse us for our research and development and medical affairs costs related to the COVID-19 Vaccine Products in accordance with agreed upon plans and budgets.

Under the Sanofi CLA, we will continue to commercialize the updated vaccine. Beginning in 2025 and continuing during the term of the Sanofi CLA, we and Sanofi will commercialize the COVID-19 Vaccine Products worldwide in accordance with a commercialization plan agreed by us and Sanofi, under which we will continue to supply our existing APA customers and strategic partners, including Takeda and SII. Upon completion of the existing APAs, we and Sanofi will jointly agree on commercialization activities of each party in each jurisdiction.

In May 2024, we also entered into the Subscription Agreement, pursuant to which we sold and issued to Sanofi, in a private placement, 6,880,481 shares of our common stock, par value $0.01 per share at a price of $10.00 per share for aggregate gross proceeds to us of $68.8 million. The opening price of our common stock on the date of the sale approximated $10.00 per share and therefore all gross proceeds were allocated to stockholders’ deficit.

We have also entered into supply agreements, sometimes referred to as APAs, with the EC and various countries globally. As of June 30, 2024, 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 licensing agreements, was approximately $2 billion, of which $1.2 billion is included in Deferred revenue on our consolidated balance sheet. Failure to timely meet regulatory milestones, obtain timely 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 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 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 COVID-19 Vaccine. Such upfront payments generally become non-refundable upon our achievement of certain development, regulatory, and commercial milestones. Additionally, for the remaining APA agreements, our intent is to amicably negotiate or deliver doses or when appropriate, exit agreements.

In October 2023, NVX-CoV2601 received EUA from the U.S. FDA for active immunization to prevent COVID-19 in individuals aged 12 and older. Immediately upon authorization, NVX-CoV2601 has also been included in the recommendations issued by the CDC in September 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. We have established reserves for gross-to-net deductions for amounts that we expect to return to our customers. As of June 30, 2024, gross-to-net reserve balances were $54.6 million related to product returns and $0.9 million related to wholesale distributor fees, discounts, and chargebacks and was included in Accrued expenses on our consolidated balance sheet.

Pursuant to the Settlement Agreement with Fujifilm (see Note 6 to our consolidated financial statements), in March 2024, we paid $42.0 million to Fujifilm, the parties agreed to a mutual release of claims arising from, under or otherwise in connection with the prior confidential settlement agreement and release effective September 30, 2022, and Fujifilm agreed to dismiss its demand for arbitration with the Judicial Arbitration and Mediation Services (“JAMS”). This payment is less than amounts previously recognized as embedded lease expense and reflected in Research and development expenses from Fujifilm manufacturing activity and accordingly, during the six months ended June 30, 2024, we recorded a benefit of $26.6 million as Research and development expenses.

We have an APA with the Commonwealth of Australia (“Australia”) for the purchase of doses of COVID-19 Vaccine (the “Australia APA”). In March 2024, we and Australia agreed to cancel the COVID-19 Vaccine doses previously scheduled for delivery in the fourth quarter of 2023. As a result of the cancellation, the total contract value was reduced by $54.0 million, including $6.0 million of deferred revenue related to the cancelled doses that will be applied as a credit towards future deliveries of doses. Australia is not required to purchase updated vaccine doses until we receive authorization from the Therapeutic Goods Administration (“TGA”). We do not expect approval in time for product delivery in 2024 which could result in a loss or deferral of approximately $240 million of contract value. We plan to seek an amendment to the Australia APA which may not be achievable on acceptable terms or at all. As of June 30, 2024, $119.1 million was classified as current Deferred revenue and $14.7 million was classified as non-current Deferred revenue with respect to the Australia APA in our consolidated balance sheet. If we are unable to satisfy our obligations under the Australia APA, $92.5 million of deferred revenue may become refundable and approximately $225 million of remaining funds under the contract may no longer be available.

In July 2024, the Pharmaceutical Management Agency (“Pharmac”), a New Zealand Crown entity, provided notice of its termination of its APA (the “New Zealand APA”). As of June 30, 2024, $31.3 million was classified as current Deferred revenue with respect to the APA in our consolidated balance sheet. New Zealand has requested a refund of certain advanced payments and we are in discussion with Pharmac on both, whether its termination of the New Zealand APA was appropriate under the New Zealand APA, and whether a refund of the advanced payments is appropriate under the New Zealand APA. Approximately $125 million of the contract value related to future deliverables may no longer be available if the APA is terminated.

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 COVID-19 Vaccine (the “Canada APA”). The Canadian government may terminate the Canada APA, as amended, if we fail to receive regulatory approval for its COVID-19 Vaccine using bulk antigen produced at Biologics Manufacturing Centre (“BMC”) Inc. on or before December 31, 2024. We do not anticipate achieving regulatory approval of our COVID-19 Vaccine using bulk antigen produced at BMC on or before December 31, 2024. Therefore, we plan to seek an amendment to the Canada APA to address possible alternatives, which may not be achievable on acceptable terms or at all. As of June 30, 2024, $452.1 million was classified as current Deferred revenue and $136.1 million was classified as non-current Deferred revenue with respect to the Canadian APA in our consolidated balance sheet. If the Canadian government terminates the Canada APA, $28.0 million of the deferred revenue would become refundable and approximately $224 million of the contract value related to future deliverables would no longer be available.

In September 2022, we entered into an Amended and Restated SARS-CoV-2 Vaccine Supply Agreement (the “Amended and Restated UK Supply Agreement”) with The Secretary of State for Business, Energy and Industrial Strategy (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 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 our 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 (“JCVI”) that is approved by the UK Secretary of State for Health. If the Authority did not purchase the Conditional Doses or the number of such Conditional Doses was reduced below 15 million doses of our prototype vaccine, we would have to repay up to $225.0 million related to the upfront payment previously received from the Authority under the Original UK Supply Agreement. Under the Amended and Restated UK Supply Agreement, the Authority also has the option to purchase up to an additional 44 million doses, in one or more tranches, through 2024.

As of November 30, 2022, the JCVI had not made a supportive recommendation with respect to 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 were 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. As of November 30, 2023, the JCVI had not made a supportive recommendation with respect to the prototype vaccine, thereby triggering a reduction in the number of Conditional Doses from 7.5 million doses to zero. As of August 2024, we are in discussions with the Authority regarding the treatment of the remaining upfront amount previously received of $112.5 million, which is reflected in Other current liabilities on our consolidated balance sheet.

We entered into an APA with the Vaccine Alliance (“Gavi”) in May 2021 (the “Gavi APA”), pursuant to which we received upfront payments of $700 million from Gavi (the “Advance Payment Amount”) to be applied against purchases of our prototype vaccine by certain countries participating in the COVAX Facility. As of December 31, 2023, the remaining Gavi Advance Payment Amount was $696.4 million. In February 2024, we and Gavi entered into a Termination and Settlement Agreement (the “Gavi Settlement Agreement”) terminating the Gavi APA, settling the arbitration proceedings, and releasing both parties of all claims arising from, under, or otherwise in connection with the Gavi APA. Pursuant to the Gavi Settlement Agreement, we are responsible for payment to Gavi of (i) an initial settlement payment of $75 million, which we paid in February 2024, and (ii) deferred payments, in equal annual amounts of $80 million payable each calendar year through a deferred payment term ending December 31, 2028. The deferred payments are due in variable quarterly installments beginning in the second quarter of 2024 and total $400 million during the deferred payment term. Such deferred payments may be reduced through Gavi’s use of an annual vaccine credit equivalent to the unpaid balance of such deferred payments each year, which may be applied to qualifying sales of any of our vaccines funded by Gavi for supply to certain low-income and lower-middle income countries. We have the right to price the vaccines offered to such low-income and lower-middle income countries in our discretion, and, when utilized by Gavi, we will credit the actual price per vaccine paid against the applicable credit. We intend to price vaccines offered via the tender process, consistent with our shared goal with Gavi to provide equitable access to those countries. Also, pursuant to the Gavi Settlement Agreement, we granted Gavi an additional credit of up to $225 million that may be applied against qualifying sales of any of our vaccines for supply to such low-income and lower-middle income countries that exceed the $80 million deferred payment amount in any calendar year during the deferred payment term. In total, the Gavi settlement agreement is comprised of $700 million of potential consideration, consisting of the $75 million initial settlement payment, deferred payments of up to $400 million that may be reduced through annual vaccine credits, and the additional credit of up to $225 million that may be applied for certain qualifying sales.

We recorded the $3.6 million difference between the refund liability recorded as of December 31, 2023 of $696.4 million and the $700 million of total consideration under the arrangement as a revenue adjustment during the six months ended June 30, 2024. As of June 30, 2024, the remaining amounts included on our consolidated balance sheet are classified as $225 million in non-current Deferred revenue for the additional credit that may be applied against future qualifying sales, $90 million in Other current liabilities, and $305 million in Other non-current liabilities. In addition, we and Gavi entered into a security agreement pursuant to which we granted Gavi a security interest in accounts receivable from SII under the SII R21 Agreement (see Note 6 to our consolidated financial statements), which will continue for the deferred payment term of the Gavi Settlement Agreement. On February 22, 2024, the claims and counterclaims were dismissed with prejudice.

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 project vaccine, as defined under the CEPI funding agreement, manufactured by the CMO network funded by CEPI is sold to one or more third parties (which could include sales credited

under the Gavi Settlement Agreement), 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.

We continue to assess our manufacturing needs and modify our global manufacturing footprint consistent with our contractual obligations to supply, and anticipated demand for, COVID-19 Vaccine, and in doing so recognize that significant costs may be incurred. For the 2023-2024 vaccination season, we have depended exclusively on Serum for co-formulation and filling (other than in Europe), and PCI Pharma Services for finishing COVID-19 Vaccine in Europe. For the 2024-2025 vaccination season, we are seeking to expand our supply chain network and introduce new single-dose vial or pre-filled syringe product presentations in certain markets. In May 2024, we and SLS entered into a supply agreement (the “SLS Supply Agreement”) under which SLS will supply us antigen drug substance and finished COVID-19 Vaccine doses. The SLS Supply Agreement includes the general terms and conditions of supply orders between us and SLS. We and SLS intend to execute statements of work and firm purchase orders to included specific quantities to be delivered under the SLS Supply Agreement. Pursuant to the SLS Supply Agreement, SLS or its authorized manufacturer is responsible for obtaining and maintaining all necessary permits or other regulatory approvals to manufacture drug substance and drug product. Unless otherwise earlier terminated, the SLS Supply Agreement will expire on the later of June 30, 2028 or two years after the expiration or termination of the last firm purchase order under the SLS Supply Agreement. Either party may terminate the SLS Supply Agreement if the other party commits a material breach of the SLS Supply Agreement that is not timely cured or is not curable. The SLS Supply Agreement contains certain customary representations and warranties of the parties along with certain customary covenants, including confidentiality and indemnity provisions. Any delays or disruptions in these suppliers’ operations could prevent or delay the delivery of customer orders.

As of June 30, 2024, we had $1.1 billion in cash and cash equivalents, restricted cash and marketable securities as compared to $583.8 million as of December 31, 2023.

We funded our operations for the six months ended June 30, 2024 primarily with cash and cash equivalents, non-refundable upfront payment under the Sanofi CLA and Subscription Agreement, proceeds from the sale of securities under our August 2023 Sales Agreement, upfront payments under APAs, and revenue from product sales. In May 2023, we announced our plan to restructure our global footprint to reduce our planned expenditures and in January 2024, we announced further reductions in our global workforce. We anticipate our future operations to be funded primarily by milestone payments, royalties and transition services under our Sanofi CLA, revenue from product sales, our cash and cash equivalents and investments in marketable securities, and other potential funding sources including equity financings, which may include at the market offerings, debt financings, collaborations, strategic alliances, asset sales, and marketing, distribution or licensing arrangements.

The following table summarizes cash flows for the six months ended June 30, 2024 and 2023 (in thousands):


	Six Months Ended June 30,
	2024		2023		Change
Net cash provided by (used in):
Operating activities	$	230,714	$	(497,531)	$	728,245
Investing activities	(379,957)		(31,337)		(348,620)
Financing activities	264,102		(293,044)		557,146
Effect on exchange rate on cash, cash equivalents, and restricted cash	(3,111)		(8,992)		5,881
Net increase (decrease) in cash, cash equivalents, and restricted cash	111,748		(830,904)		942,652
Cash, cash equivalents, and restricted cash at beginning of period	583,810		1,348,845		(765,035)
Cash, cash equivalents, and restricted cash at end of period	$	695,558	$	517,941	$	177,617

Net cash provided by operating activities was $230.7 million for the six months ended June 30, 2024, as compared to net cash used in operating activities of $497.5 million for the same period in 2023. The increase in cash provided by operating activities is primarily due to the non-refundable upfront payment under the Sanofi CLA, an increase in amounts received under our APAs and an overall decrease in operating expenses period-over-period, partially offset by the timing of payments to vendors.

Net cash used in investing activities was $380.0 million for the six months ended June 30, 2024, as compared to $31.3 million for the same period in 2023. The increase in cash used in investing activities is primarily due to our investment in marketable securities, partially offset by lower expenditures on equipment and leasehold improvements.

Net cash provided by financing activities was $264.1 million for the six months ended June 30, 2024, as compared to net cash used in financing activities of $293.0 million for the same period in 2023. The increase in cash provided by financing activities is primarily as a result of proceeds from the sale of shares under our August 2023 Sales Agreement of approximately $188 million and Subscription Agreement of $68.8 million in 2024 as compared with the $325 million repayment of our 3.75% Convertible notes and finance lease payments during 2023.

Going Concern

As described in Note 2 to our consolidated financial statements, we evaluated our ability to continue as a going concern and concluded that we will have sufficient capital available to fund our operations for at least one-year from the date that the financial statements were issued.

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 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 $57.2 million as of June 30, 2024.

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. 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 30, 2024. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and

management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving such control objectives. Based on the evaluation of our disclosure controls and procedures as of June 30, 2024, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

Our management, including our chief executive officer and chief financial officer, have evaluated changes in our internal control over financial reporting that occurred during the quarter ended June 30, 2024, and have concluded that there have been no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

Stockholder Litigation

On 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 May 10, 2022, the Maryland Court entered an order granting the parties’ request to stay all proceedings and deadlines pending the earlier of dismissal or the filing of an answer in the Sinnathurai Action. On June 10, 2022, the Snyder and Blackburn Actions were filed. On October 5, 2022, the Maryland Court entered an order granting a request by the plaintiffs in the First Consolidated Derivative Action and the Snyder and Blackburn Actions to consolidate all three actions and appoint co-lead plaintiffs and co-lead and liaison counsel (the “Second Consolidated Derivative Action”). The co-lead plaintiffs in the Second Consolidated Derivative Action filed a consolidated amended complaint on November 21, 2022. On February 10, 2023, defendants filed a motion to dismiss the Second Consolidated Derivative Action. The plaintiffs filed their opposition to the motion to dismiss on April 11, 2023. Defendants filed their reply brief in further support of their motion to dismiss on May 11, 2023. On August 21, 2023, the court entered an order granting in part and denying in part the motion to dismiss. On September 5, 2023, the Company filed an Answer to the consolidated amended complaint. On September 6, 2023, the court entered an order granting the individual defendants an extension of time to file their answer until November 6, 2023. 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, and, on April 15, 2024, the court entered a further order extending the stay until June 6, 2024. On June 7, 2024, the court entered another order extending the stay until August 5, 2024. On August 5, 2024, the parties agreed to a further 90-day extension to November 4, 2024, which remains subject to court approval. The existing and proposed stays include the deadline for the individual defendants to respond to the consolidated amended complaint.

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, 2023, which was filed with the SEC on February 28, 2024 and Part II, Item 1A. “Risk Factors” of our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2024, which was filed with the SEC on May 10, 2024. 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, 2023 and the Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2024, other than as described below.

Risks Related to Product Development and Commercialization

We must identify vaccines for development with our technologies and establish successful third-party relationships.

The near and long-term viability of our vaccine candidates depend in part on our ability to successfully establish new strategic collaborations with pharmaceutical and biotechnology companies, non-profit organizations and government agencies. Establishing strategic collaborations and obtaining government funding is difficult and time-consuming. Potential collaborators may reject collaborations based upon their assessment of our financial, regulatory or intellectual property position or based on their existing pipelines; government agencies may reject contract or grant applications based on their assessment of public need, the public interest, our products’ ability to address these areas, or other reasons beyond our expectations or control. Collaborators also may seek to modify or terminate relationships, which may be difficult and time-consuming, and ultimately may not be successful and lead to the collaborator rejecting the collaboration. Past success in establishing strategic collaborations with pharmaceutical and biotechnology companies, non-profit organizations and government agencies is no guarantee of future success in entering into new relationships or in performing under existing relationships. Our existing collaborations, including with Sanofi under the Sanofi CLA for the co-commercialization of Nuvaxovid and other vaccines that include Nuvaxovid together with influenza and other antigens, may limit interest in partnering opportunities with respect to our CIC and other products. If we fail to establish a sufficient number of collaborations or government relationships on acceptable terms, or fail to perform under collaborations or relationships to the satisfaction of counter-parties, then we may not be able to commercialize our vaccine candidates or generate sufficient revenue to fund further research and development efforts.

The collaborations we have established, including the Sanofi CLA, or may establish, may not result in the successful development or commercialization of any vaccine candidates for several reasons, including the fact that:

▪we may not have the ability to control the activities of our partners and cannot provide assurance that they will fulfill their obligations to us, including with respect to the license, development and commercialization of vaccine candidates, in a timely manner or at all;

▪such partners may not devote sufficient resources to our vaccine candidates or properly prosecute, maintain or defend our intellectual property rights;

▪our partners could independently develop, or develop with third parties, products that compete directly or indirectly with our vaccine candidates if such partners believe that competitive products are more likely to be successfully developed or can be commercialized under terms that are more economically attractive than ours;

▪any failure on the part of our partners to perform or satisfy their obligations to us could lead to delays in the development or commercialization of our vaccine candidates and affect our ability to realize product revenue, including with respect to Sanofi under the Sanofi CLA, revenue for our only commercial-stage product against COVID-19; and

▪disagreements, including disputes over the ownership of technology developed with such collaborators, could result in litigation, which would be time consuming and expensive, and may delay or terminate research and development efforts, regulatory approvals and commercialization activities.

If we or our collaborators fail to maintain our existing agreements or in the event we fail to establish agreements as necessary, then we could be required to undertake research, development, manufacturing and commercialization activities solely at our own expense. These activities would significantly increase our capital requirements and, given our lack of sales, marketing and distribution capabilities, significantly delay the commercialization of our vaccine candidates.

Risks Related to Our Financial Condition and Capital Requirements

Our existing funding and supply agreements or our advance purchase agreements do not assure success of our vaccine candidates or vaccines or that we will be able to fully fund our vaccine candidates or vaccines or our company operations, and if we are unable to satisfy the performance obligations under such agreements the agreements may be terminated, the purchase commitments may be reduced or we may be required to refund advanced payments.

We have entered into, and may in the future enter into supply agreements (also sometimes referred to as advance purchase agreements) for our COVID-19 Vaccine that include prepayments from the purchasers to help fund our development and manufacture of the vaccine. Under certain supply agreements, if we do not timely achieve requisite regulatory milestones for our COVID-19 Vaccine in the relevant jurisdictions, obtain supportive recommendations from governmental advisory committees, and/or achieve product volume or delivery timing obligations, purchasers may seek to terminate such agreements, reduce their purchase commitments, require us to refund all or some prepayments we have received, or renegotiate such agreements, each of which could have a material and adverse effect on our financial condition. 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 prototype vaccine under certain of our supply agreements. 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 COVID-19 Vaccine. Such upfront payments generally become non-refundable upon our achievement of certain development, regulatory and commercial milestones. We may not achieve such milestones, which could have a material and adverse effect on our financial condition.

For example, in September 2022, following a delay in obtaining regulatory approval in the United Kingdom, we entered into the Amended and Restated UK Supply Agreement, which amended and restated in its entirety the Original UK Supply Agreement, which reduced the volume of vaccine doses that the Authority committed to purchase. 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 our prototype vaccine, with the number of Conditional Doses contingent on, and subject to reduction based on, our timely achievement of supportive recommendations from the JCVI that is approved by the UK Secretary of State for Health. If the Authority did not purchase the Conditional Doses or the number of such Conditional Doses was reduced below 15 million doses of our prototype vaccine, we would have to repay up to $225.0 million related to the upfront payment previously received from the Authority under the Original UK Supply Agreement. Under the Amended and Restated UK Supply Agreement, the Authority also has the option to purchase up to an additional 44 million doses, in one or more tranches, through 2024. As of November 30, 2022, the JCVI had not made a supportive recommendation with respect to our prototype vaccine, thereby triggering (i) a reduction of the number of Conditional Doses from 15 million doses to 7.5 million doses, which reduced number of Conditional Doses were 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 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. As of November 30, 2023, the JCVI had not made a supportive recommendation with respect to the prototype vaccine, thereby triggering a reduction in the number of Conditional Doses from 7.5 million doses to zero.

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 COVID-19 Vaccine (the “Canada APA”). The Canadian government may terminate the Canada APA, as amended, if we fail to receive regulatory approval for its COVID-19 Vaccine using bulk antigen produced at Biologics Manufacturing Centre (“BMC”) Inc. on or before December 31, 2024. We do not currently anticipate achieving regulatory approval of our COVID-19 Vaccine using bulk antigen produced at BMC on or before December 31, 2024. Therefore, in parallel, we plan to work with the Canadian government on an amendment that addresses possible alternatives, which may not be achievable on acceptable terms or at all. As of June 30, 2024, $452.1 million was classified as current Deferred revenue and $136.1 million was classified as non-current Deferred revenue with respect to the Canadian APA in our consolidated balance sheet. If the Canadian government terminates the Canada APA, $28.0 million of the deferred revenue would become refundable and approximately $224 million of the contract value related to future deliverables would no longer be available.We are working with the Canadian Government on an amendment to the APA that addresses regulatory approval and future delivery schedules, which may not be achievable on acceptable terms or at all.

Item 5. Other Information

During the three months ended June 30, 2024, certain of our directors and “officers” (as defined in Rule 16a-1(f) under the Securities Exchange Act of 1934, as amended) adopted or terminated contracts, instructions or written plans for the purchase or sale of our securities that are intended to satisfy the conditions specified in Rule 10b5-1(c) under the Securities Exchange Act of 1934, as amended, for an affirmative defense against liability for trading in securities on the basis of material nonpublic information. We refer to these contracts, instructions and written plans as “Rule 10b5-1 trading plans” and each one as a “Rule 10b5-1 trading plan.” We describe the material terms of these Rule 10b5-1 trading plans below.
