Revenue Recognition, Product Sales - Advance Purchase Agreements

Current wording

Revenue Recognition, Product Sales - Advance Purchase Agreements (“APAs”)

Previous wording

Product sales include sales associated with COVID-19 Vaccine supply agreements, sometimes referred to as advance purchase agreements (“APAs”), with various international governments. We recognize revenue from product sales related to these APA’s based on the transaction price per dose calculated in accordance with Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers, at the point in time when control of the product transfers to the customer and customer acceptance has occurred, unless such acceptance provisions are deemed perfunctory. The APAs typically contain terms that include upfront payments which are reflected in Deferred revenue. We constrain the transaction price for APA’s until it is probable that a significant reversal in revenue recognized will not occur. Specifically, if an APA includes a provision whereby the customer may request a discount, return, or refund, or includes a term that may have the effect of decreasing the price per dose of previously delivered shipments, revenue is constrained based on an estimate of the impact of the transaction price until it is probable that a significant reversal in revenue recognized will not occur.

Previous wording

In the fourth quarter of 2023, we commenced sales of COVID-19 Vaccine to the U.S. commercial market. Product sales in the U.S. are primarily made through large pharmaceutical wholesale distributors at the wholesale acquisition cost (“WAC”). We recognize revenue upon title transfer (which is typically at time of delivery), provided all other revenue recognition criteria have been met. The transaction price includes estimates of variable consideration for which reserves are established that primarily result from invoice discounts for prompt payment, wholesale distributor fees, chargebacks, and product returns (collectively, “gross-to-net deductions”). These estimates are based on the amounts earned or to be claimed for related sales and are classified as either reductions of gross accounts receivable or a current liability based on the nature of the estimate, the expected settlement method, and net position by individual customer. Where appropriate, these estimates are based on factors such as industry data and forecasted customer buying and payment patterns, our experience, current contractual and statutory requirements, specific known market events, and trends. Variable consideration is included in the transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. If actual results vary from estimates, we will adjust the estimates, which would affect product sales in the period such variances become known.

•Product returns: We offer U.S. customers the right to return COVID-19 Vaccine. These return rights include the right of wholesale distributors to return unsold and expired doses and the right of indirect customers to return any partial or unused vials upon expiry. Estimated returns for COVID-19 Vaccine are determined considering levels of inventory in the distribution channel, projected market demand, utilization data, returns claims received, and product shelf life. Our estimates of product returns are subject to significant uncertainty. Actual customer product returns could vary significantly from our estimates, resulting in changes to the estimates in subsequent periods. The estimated amount for product returns is deducted from gross product sales in the period the related product sales are recognized.

We periodically analyze our inventories for excess amounts or obsolescence and write down obsolete or otherwise unmarketable inventory to its estimated net realizable value. We estimate excess or obsolete inventory and losses on firm purchase commitments of inventory quarterly based on multiple factors, including assumptions about expected future demand and market conditions, current sales orders, and product expiry dates. Our assumptions about expected future demand are inherently uncertain and if we were to change any of these judgments or estimates, it could cause a material increase or decrease in the amount of inventory write down that we report in a particular period. We began to capitalize inventory in 2022. Subsequently, for the year ended, December 31, 2022 we recorded inventory write-downs of $447.6 million and losses on firm purchase commitments of inventory of $155.9 million to the extent the cost cannot be recovered based on estimates about future demand. For the year ended December 31, 2023, we recorded inventory write-downs of $72.4 million and losses on firm purchase commitments of inventory of $73.5 million. In addition, for the year ended December 31, 2023, we recorded recoveries on firm purchase commitments of $40.2 million related primarily to negotiated reductions to previously recognized firm purchase commitments.

Previous wording

Revenue for the year ended December 31, 2023 was $983.7 million as compared to $2.0 billion for the year ended December 31, 2022, a decrease of $1.0 billion. Revenue for the years ended December 31, 2023 and 2022 was primarily comprised of revenue from 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 primarily due to a decreased quantity of dose sales of COVID-19 Vaccine.

Current wording

Revenue for the year ended December 31, 2024 was $682.2 million as compared to $983.7 million for the year ended December 31, 2023, a decrease of $301.5 million. Revenue for the year ended December 31, 2024, was primarily comprised of revenue from licensing and product sales of COVID-19 Vaccine. Revenue for the year ended December 31, 2023, was primarily comprised of revenue from product sales of COVID-19 Vaccine and services performed under our USG Agreement. The decrease in revenue is due to a decrease in revenue under the USG Agreement and in the quantity of dose sales of COVID-19 Vaccine, partially offset by licensing, royalties, and other revenue from the Sanofi CLA.

Previous wording

Product sales for 2023 were $531.4 million as compared to $1.6 billion for 2022, a decrease of $1.0 billion. The decrease in product sales is primarily due to a decreased quantity of dose sales of COVID-19 Vaccine during the year ended December 31, 2023 as compared to 2022. Product sales for 2023 related to revenue from commercial sales of COVID-19 Vaccine, which commenced in 2022. The geographic distribution of product sales in 2023 was as follows:

Current wording

Product sales for 2024 were $190.2 million as compared to $531.4 million for 2023, a decrease of $341.2 million.

The geographic distribution of product sales was as follows:

Previous wording

Grant revenue for 2023 was $427.3 million compared to $382.9 million for 2022, an increase of $44.4 million. Grant revenue comprised revenue for services performed under our USG Agreement. The increase was primarily due to increased support activities under the USG Agreement during 2023. As of December 31, 2023, the Company has recognized the full contract funding under the USG Agreement in revenue.

Current wording

We did not have any Grants revenue during the year ended December 31, 2024, as compared to $427.3 million during the year ended December 31, 2023, a decrease of $427.3 million. Grant revenue for the year ended December 31, 2023 was comprised of 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.

Previous wording

Cost of sales was $343.8 million, or 65% of product sales, for the year ended December 31, 2023, including expense of $145.9 million related to excess, obsolete, or expired inventory and losses on certain firm purchase commitments, $6.1 million ROU asset impairment charges for CMO manufacturing capacity of excess quantities, $64.0 million related to unutilized manufacturing capacity, and a credit of $40.2 million related to negotiated reductions to certain previously recognized firm purchase commitments. Cost of sales was $902.6 million, or 58% of product sales, for 2022, including expense of $603.5 million related to excess, obsolete, or expired inventory and losses on firm purchase commitments. Prior to receiving approval, we expensed manufacturing costs as research and development expenses. After receiving approval, we capitalize the costs of production for a particular supply chain when we determine that we have a present right to the economic benefit associated with the product. While we tracked the quantities of our manufactured vaccine product and components, we did not track pre-approval manufacturing costs and therefore the manufacturing cost of our pre-launch inventory produced prior to approval is not reasonably determinable. If inventory sold during 2023 was valued at expected standard cost, including expenses related to excess and obsolete inventory, adjusted cost of sales for the year would have been $382.8 million, an adjustment of $39.0 million as compared to cost of sales recognized. If inventory sold during 2022 was valued at expected standard cost, adjusted cost of sales for the year would have been approximately $1.1 billion, an adjustment of $164.8 million. The cost of sales as a percentage of product sales may fluctuate in the future as a result of changes to our customer mix or standard costs.

Current wording

Cost of sales decreased to $202.7 million for 2024 as compared to $343.8 million for 2023, a decrease of $141.0 million. The decrease was primarily due to a decrease in the quantity of dose sales of COVID-19 Vaccine and a decrease in excess, obsolete, or expired inventory and losses on certain firm purchase commitments. Cost of sales for 2024 included expense of $28.4 million related to excess, obsolete, or expired inventory and losses on certain firm purchase commitments, $3.8 million ROU asset impairment charges for CMO manufacturing capacity of excess quantities, $44.9 million related to unutilized manufacturing capacity, and a credit of $0.7 million related to negotiated reductions to certain previously recognized firm purchase commitments. Cost of sales for 2023 included expense of $145.9 million related to excess, obsolete, or expired inventory and losses on firm purchase commitments, $6.1 million ROU asset impairment charges for CMO manufacturing capacity of excess quantities, $64.0 million related to unutilized manufacturing capacity, and a credit of $40.2 million related to negotiated reductions to certain previously recognized firm purchase commitments. The cost of sales as a percentage of product sales may fluctuate in the future as a result of changes to our customer mix, quantity of dose sales, or standard costs.

Previous wording

Research and development expenses decreased to $737.5 million for 2023 as compared to $1.2 billion for 2022, a decrease of $497.8 million. The decrease was primarily due to a reduction in overall expenditures relating to development activities on coronavirus vaccines, including our COVID-19 Vaccine and CIC, as summarized in the table below (in thousands):

Current wording

Research and development expenses decreased to $391.2 million for 2024 as compared to $737.5 million for 2023, a decrease of $346.3 million. The decrease was primarily due to a reduction in overall expenditures relating to development activities on coronavirus vaccines, including our COVID-19 Vaccine and CIC, as summarized in the table below (in thousands):

Previous wording

Research and development expenses for coronavirus vaccines for the year ended December 31, 2023 and 2022 decreased to $413.4 million from $848.0 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 under manufacturing supply agreements with CMOs and CDMOs, and a reduction in clinical study costs and the commercialization of internal manufacturing capabilities. The decrease was also due to a benefit of $57.7 million during the year ended December 31, 2023 resulting from our settlement agreement and Private Placement with SK (see Note 4 to our consolidated financial statements). The decrease was partially offset by a benefit of $35.2 million and $201.4 million for the years ended December 31, 2023 and 2022, respectively, related to previously accelerated manufacturing costs for leases that we determined were embedded in manufacturing supply agreements with CMOs and CDMOs.

Current wording

Research and development expenses for coronavirus vaccines for the year ended December 31, 2024 and 2023 decreased to $122.4 million from $413.4 million primarily as a result of a reduction in coronavirus vaccines clinical and support costs. The decrease was also the 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.

Previous wording

For 2024, we expect research and development expenses to decrease as compared to 2023 as 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 as additional manufacturing activities that were previously recognized as research and development expenses begin to meet the criteria for capitalization as inventory.

Current wording

For 2025, we expect research and development expenses to decrease as compared to 2024 as we continue to right-size our operating expenses as part of our cost reduction initiative.

Selling, general, and administrative expenses decreased to $468.9 million for 2023 from $488.7 million for 2022, a decrease of $19.7 million. The decrease in selling, general, and administrative expenses is primarily due to cost containment measures to reduce our operating spend including a decrease in professional fees and advertising and promotion costs in support of our COVID-19 commercial program, partially offset by restructuring expenses.

Current wording

Selling, general, and administrative expenses decreased to $337.2 million for 2024 from $468.9 million for 2023, a decrease of $131.8 million. The decrease in selling, general, and administrative expenses is primarily due to cost containment measures to reduce our operating spend, including a decrease in advertising and promotion costs in support of our COVID-19 commercial program, employee expenses, and professional fees, partially offset by restructuring expenses.

Previous wording

We had total net other income of $23.5 million for 2023 compared to total net other expense of $8.9 million for 2022, an increase of $32.4 million. During 2023, other income, net increased primarily due to the favorable impact in 2023 as compared to 2022 of exchange rates on foreign currency denominated balances, including an intercompany loan with Novavax CZ, and an increase in investment income due to higher interest rates.

Current wording

We had total net other income of $72.3 million for 2024 compared to total net other income of $23.5 million for 2023, an increase of $48.8 million. The increase in other income (expense), net is primarily due to the gain on the disposition of Novavax CZ assets, the favorable impact in 2024 as compared to 2023, of exchange rates on foreign currency denominated balances, including an intercompany loan with Novavax CZ, and additional interest income on Cash and cash equivalents and Marketable securities balances, partially offset by additional interest expense.

Previous wording

During the years ended December 31, 2023 and 2022, we recognized $2.0 million and $4.3 million of income tax expense, respectively, related to federal, state, and foreign income taxes.

Current wording

During the years ended December 31, 2024 and 2023, we recognized $10.9 million and $2.0 million of income tax expense, respectively, related to federal, state, and foreign income taxes.

Previous wording

Net loss for 2023 was $545.1 million, or $5.41 per share, as compared to $657.9 million, or $8.42 per share, for 2022, a decrease of $112.9 million, or $3.01 per share. The decrease in net loss was primarily due to the decline in cost of sales and research and development expenses associated with our COVID-19 Vaccine, partially offset by a decrease in revenue from product sales.

Current wording

Net loss for 2024 was $187.5 million, or $1.23 per share, as compared to $545.1 million, or $5.41 per share, for 2023, a decrease of $357.6 million, or $4.18 per share. The decrease in net loss during the years ended December 31, 2024, was primarily due to a decrease in total expenses, partially offset by a decrease in total revenue.

Previous wording

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

Current wording

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 and stand-alone influenza vaccine candidates, including significant commitments under various CRO, CMO, and CDMO agreements; the progress of preclinical studies and clinical trials; the time and costs involved in obtaining regulatory approvals; the costs of filing, prosecuting, defending, and enforcing patent claims and other intellectual property rights; and other manufacturing, sales, and distribution costs. We plan to continue developing other vaccines and product candidates, such as our potential combination vaccine and stand-alone influenza vaccine 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 18 to our accompanying 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.

We have entered into supply agreements, sometimes referred to as APAs, with the EC and various countries globally. We also have license agreements. As of December 31, 2023, the aggregate amount of the transaction price allocated to performance obligations that were unsatisfied (or partially unsatisfied), excluding amounts related to sales-based royalties under the licensing agreements, was approximately $2 billion, of which $863.5 million is included in Deferred revenue on our consolidated balance sheet. Failure to timely meet regulatory milestones, 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 in place of the prototype 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.

Current wording

We have also entered into supply agreements, sometimes referred to as APAs, with various countries globally. As of December 31, 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 $1.3 billion, of which $1.1 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 or result in the reversal of previously recognized revenue. In the first quarter of 2025, we received written notice of a $23 million claim related to certain performance obligations under an APA agreement with a customer. We believe we have fulfilled the requirements related to this matter and are evaluating the merits of the claim. The timing to fulfill performance obligations related to APAs will depend on timing of product manufacturing, receipt of marketing authorizations for additional indications, delivery of doses based on customer demand, and the ability of the customer to request variant vaccine under certain of our APAs. The APAs 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 deliver doses or when appropriate, amicably negotiate and exit agreements. The timing to fulfill performance obligations related to the Sanofi CLA will depend on the timing of costs incurred relative to total expected costs.

On October 3, 2023, our updated vaccine received EUA from the U.S. FDA for active immunization to prevent COVID-19 in individuals aged 12 and older. Immediately upon authorization, our updated vaccine has also been included in the recommendations issued by the CDC 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 December 31, 2023, gross-to-net reserve balances are $84.6 million related to product returns and $21.1 million related to wholesale distributor fees, discounts, and chargebacks, of which $103.1 million is included in Accrued expenses and $2.6 million is included in Accounts receivable on our consolidated balance sheet.

Under the terms of the Gavi APA, we received an upfront payment of $350.0 million from Gavi in 2021 and an additional payment of $350.0 million in 2022 related to our achieving EUL for our prototype vaccine by the WHO (the “Advance Payment Amount”). On November 18, 2022, we delivered written notice to Gavi to terminate the Gavi APA on the basis of Gavi’s failure to procure the purchase of 350 million doses of our prototype vaccine from us as required by the Gavi APA. As of November 18, 2022, we had only received orders under the Gavi APA for approximately 2 million doses. On December 2, 2022, Gavi issued a written notice purporting to terminate the Gavi APA based on Gavi’s contention that the Company repudiated the agreement and, therefore, materially breached the Gavi APA. Gavi also contended that, based on its purported termination of the Gavi APA, it was entitled to a refund of the Advance Payment Amount less any amounts that have been credited against the purchase price for binding orders placed by a buyer participating in the COVAX Facility. As of December 31, 2023, the remaining Gavi Advance Payment Amount of $696.4 million, pending resolution of the dispute with Gavi related to a return of the remaining Advance Payment Amount, was reclassified from Deferred revenue to Other current liabilities on our consolidated balance sheet. On January 24, 2023, Gavi filed a demand for arbitration with the International Court of Arbitration based on the claims described above. We filed our Answer and Counterclaims on March 2, 2023. On April 5, 2023, Gavi filed its Reply to our Counterclaims. On February 16, 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 on February 20, 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 first 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 at 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 sha…

Current wording

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.

Previous wording

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 depend exclusively on SIIPL and SLS 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. Any delays or disruptions in these suppliers’ operations could prevent or delay the delivery of customer orders.

For the 2024-2025 vaccination season, we expanded our supply chain network and introduced new single-dose vial and 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 execute firm purchase orders to include 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.

Previous wording

Net cash used in operating activities was $714.0 million for 2023, as compared to cash used in operating activities of $415.9 million in 2022. The increase in cash used in operating activities is primarily due to the timing of payments to vendors and cash receipts from customers, primarily APAs.

Current wording

Net cash used in operating activities was $87.3 million for 2024, as compared to cash used in operating activities of $714.0 million in 2023. The decrease in cash used in operating activities is primarily due to the non-refundable upfront payment under the Sanofi CLA and an overall decrease in operating expenses period-over-period, partially offset by the timing of payments to vendors.

Previous wording

Net cash used in investing activities was $58.8 million for 2023, as compared to $93.0 million in 2022.

Current wording

Net cash provided by financing activities was $260.6 million for 2024, as compared to $4.5 million in 2023. The increase in cash provided by financing activities is primarily as a result of the 2023 repayment of $325.0 million of our 3.75% Convertible notes in 2023, partially offset by lower proceeds from the sale of shares under our August 2023 Sales Agreement and Sanofi Subscription Agreement, totaling $263.3 million in 2024, as compared with proceeds from the sale of shares under our June 2021 Sales Agreement and August 2023 Sales Agreement and the sale of SK Shares, totaling $360.2 million in 2023.

In accordance with ASC Topic 205-40, Presentation of Financial Statements - Going Concern, we evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the date that these consolidated financial statements are issued. While our current cash flow forecast for the one-year going concern look forward period estimates that we have sufficient capital available to fund operations, this forecast is subject to significant uncertainty, including as it relates to revenue for the next twelve months and our ability to execute on certain cost-reduction initiatives. Our revenue projections depend on our ability to successfully develop, manufacture, distribute, or market our COVID-19 Vaccine for the 2024-2025 vaccination season, which is inherently uncertain and subject to a number of risks, including our ability to obtain regulatory authorizations, introduce a single-dose vial or pre-filled syringe product presentation for the U.S. commercial and certain other markets, the incidence of COVID-19 during the 2024-2025 vaccination season, our ability to timely deliver doses and commercial adoption and market acceptance of our updated vaccine.

Current wording

In accordance with Accounting Standards Codification (“ASC”) Topic 205-40, Presentation of Financial Statements - Going Concern, we evaluated our ability to continue as a going concern within one year after the date that the accompanying consolidated financial statements are issued. Based on our current cash, cash equivalents and marketable securities balances and our current cash flow forecast for the one-year going concern look forward period, we concluded that we expect to have sufficient capital available to fund our operations for the one-year period from the date that these financial statements are issued. As of December 31, 2023, we had concluded that there was substantial doubt about our ability to continue as a going concern primarily due to significant uncertainty related to our ability to successfully develop, manufacture, distribute, and market our COVID-19 Vaccine and execute on certain cost-reduction initiatives. The Sanofi CLA, combined with proceeds from the disposition of assets held by Novavax CZ, cost reductions and the settlement of certain liabilities, alleviated the substantial doubt.
