The Company's accounts receivable included $43.6 million and $419.7 million related to amounts that were billed to customers and $68.0 million and $35.3 million related to amounts which had not yet been billed to customers as of September 30, 2022 and December 31, 2021, respectively. During the nine months ended September 30, 2022, changes in the Company's accounts receivables and deferred revenue balances were as follows (in thousands):

The aggregate amount of the transaction price allocated to performance obligations that were unsatisfied (or partially unsatisfied), excluding amounts related to sales-based royalties, was approximately $4 billion as of September 30, 2022. Failure to meet regulatory milestones, timely obtain supportive recommendations from governmental advisory committees, or achieve product volume or delivery timing obligations under the Company’s APA agreements may require the Company to refund portions of upfront payments or result in reduced future payments, which could adversely impact the Company’s ability to realize revenue from its unsatisfied performance obligations. The timing to fulfill performance obligations related to grant agreements will depend on the results of the Company's research and development activities, including clinical trials, and delivery of doses. The timing to fulfill performance obligations related to APAs will depend on timing of product manufacturing, receipt of marketing authorizations for additional indications, delivery of doses based on customer demand, and the ability of the customer to request variant vaccine in place of the prototype NVX-CoV2373 vaccine under certain of our APAs. The remaining unfilled performance obligations not related to grant agreements or APAs are expected to be fulfilled in less than 12 months.

The Company’s U.S. government partnership consists of an agreement (the “OWS Agreement”) with Advanced Technology International, the Consortium Management Firm acting on behalf of the Medical CBRN Defense Consortium in connection with the partnership formerly known as Operation Warp Speed (“OWS”). In July 2022, the Company entered into a modification to the OWS Agreement that amended the terms of such agreement to provide for (i) an initial delivery to the U.S. government of approximately 3 million doses of NVX-CoV2373 and (ii) any additional manufacture and delivery to the U.S. government up to an aggregate of 100 million doses of NVX-CoV2373 contemplated by the original OWS Agreement (inclusive of the initial batch of approximately 3 million doses) dependent on U.S. government demand, FDA guidance on strain selection, agreement between the parties on the price of such doses, and available funding. The 3 million initial doses were delivered in July 2022. Additionally, in July 2022, the Company modified its existing agreement with the DoD and delivered 0.2 million doses of NVX-CoV2373 after receipt of EUA approval from the FDA, with delivery of the remaining 9.8 million doses of NVX-CoV2373 contemplated by the original agreement subject to DoD demand and available funding.

The Company’s funding agreement with CEPI, under which CEPI has agreed to provide funding of up to $399.5 million to the Company to support the development of NVX-CoV2373, provides up to $257.0 million in grant funding and up to $142.5 million in forgivable no-interest term loans. These loans are only repayable if NVX-CoV2373 manufactured by the CMO network funded by CEPI is sold under the Company’s APA with Gavi, the Vaccine Alliance (“Gavi”), and such sales cover the Company’s costs of manufacturing the vaccine, not including manufacturing costs funded by CEPI. The timing of any loan repayments is currently uncertain given the timing and quantities of future orders under the Company’s APA with Gavi are unclear, as discussed below.

During the three and nine months ended September 30, 2022, the Company recognized $1.3 million and $10.5 million, respectively, in revenue related to sales-based royalties. During the three months ended June 30, 2022, the Company recognized a $20.0 million milestone payment upon the sale of NVX-CoV2373 in Japan. During the three and nine months ended September 30, 2021, the Company recognized $39.9 million and $63.4 million, respectively, in revenue related to sales-based royalties. During the three and nine months ended September 30, 2021, the Company did not recognize any revenue related to milestone payments.

Under the terms of the Company’s supply commitment with Gavi, which includes both Novavax’ APA with Gavi and the supply obligation of its licensed partner, Serum Institute of India Private Limited (“SIIPL”), 1.1 billion doses of NVX-CoV2373 are to be made available to countries participating in the COVAX Facility, which was established to allocate and distribute vaccines equitably to participating countries and economies. The Novavax APA contemplates that the Company will manufacture and distribute 350 million doses. Under that agreement with Gavi, the Company received an upfront payment of $350 million from Gavi in 2021 and an additional payment of $350 million in the first quarter of 2022 related to the Company’s achieving WHO Emergency Use Listing. Although Novavax continues to be prepared to deliver the quantities of NVX-CoV2373 doses to Gavi under the terms of the APA, the Company was notified by Gavi of its intent to seek to revise the number and timing of doses of NVX-CoV2373 supplied by Novavax under such agreement. Furthermore, Gavi may seek partial or full recovery of the prior nonrefundable payments it has made to Novavax. The Company’s position is that Gavi has no contractual right to recover prior nonrefundable payments if it fails to order the 350 million doses it committed to order. To date, except for an initial order of approximately 2 million doses, Novavax has not received an order from Gavi and the timing and quantities of future orders to deliver NVX-CoV2373 to the COVAX Facility are unclear.

Under the terms of the Company’s SARS-CoV-2 Vaccine Supply Agreement, originally entered into in October 2020 (the “Original UK Supply Agreement”) with The Secretary of State for Business, Energy and Industrial Strategy, acting on behalf of the government of the United Kingdom of Great Britain and Northern Ireland (the “Authority”), the Authority agreed to purchase 60 million doses of NVX-CoV2373. In July 2022, the Company entered into an Amended and Restated SARS-CoV-2 Vaccine Supply Agreement (the “Amended and Restated UK Supply Agreement”) with the Authority, under which the Authority agreed to purchase a minimum of 1 million doses and up to an additional 15 million doses of NVX-CoV2373, with the number of additional doses contingent on the Company’s timely achievement of supportive recommendations from the Joint Committee on Vaccination and Immunisation (the “JCVI”). In the event that the Company is unable to achieve the JCVI supportive recommendations, it may have to repay up to $225.0 million related to the upfront payment previously received from the Authority under the Original UK Supply Agreement. As of September 30, 2022, the Company will be required to repay a minimum of $40.0 million related to the upfront payment, which is reflected in Other current liabilities, with the remaining balance of $185.0 million reflected in Deferred revenue. Under the Amended and Restated UK Supply Agreement, the Authority also has the option to purchase up to an additional 44 million doses, in one or more tranches, through 2024.

The Company has an APA with the European Commission (“EC”) acting on behalf of various European Union member states to supply a minimum of 20 million and up to 100 million initial doses of NVX-CoV2373, with the option for the EC to purchase an additional 100 million doses up to a maximum aggregate of 200 million doses in one or more tranches, through 2023. In July and August 2022, the Company was notified by the EC that it was cancelling 5 million doses of its prior commitment originally scheduled for delivery in the first and second quarters of 2022, in accordance with the APA, and reducing the order to 65 million doses. The Company is in the process of finalizing a revised delivery schedule for the remaining 23 million committed doses under the APA that were originally scheduled for delivery during the first and second quarters of 2022.

The Company previously granted SIIPL exclusive and non-exclusive licenses for the development, co-formulation, filling and finishing, registration, and commercialization of NVX-CoV2373. SIIPL agreed to purchase the Company’s Matrix-MTM adjuvant and the Company granted SIIPL a non-exclusive license to manufacture the antigen drug substance component of NVX-CoV2373 in SIIPL’s licensed territory solely for use in the manufacture of NVX-CoV2373. The Company and SIIPL equally split the revenue from SIIPL’s sale of NVX-CoV2373 in its licensed territory, net of agreed costs. The Company also has a supply agreement with SIIPL and Serum Life Sciences Limited (“SLS”) under which SIIPL and SLS supply the Company with NVX-CoV2373 for commercialization and sale in certain territories, as well as a contract development manufacture agreement with SLS, under which SLS manufactures and supplies finished vaccine product to the Company using antigen drug substance and Matrix-M™ adjuvant supplied by the Company. In May and August 2022, the Company expanded its license and supply arrangements with SIIPL to include its proprietary COVID-19 variant antigen candidate(s), its quadrivalent influenza vaccine candidate, and its CIC vaccine candidate, so that SIIPL can manufacture and commercialize a vaccine targeting COVID-19 variants, including the Omicron subvariants, a quadrivalent influenza vaccine, and CIC vaccine, and supply such vaccines to the Company. In March 2020, the Company granted SIIPL a non-exclusive license for the use of Matrix-M™ adjuvant supplied by the Company to develop, manufacture, and commercialize R21, a malaria candidate developed by the Jenner Institute, University of Oxford.

The Company has a collaboration and license agreement with Takeda Pharmaceutical Company Limited (“Takeda”) under which the Company granted Takeda an exclusive license to develop, manufacture, and commercialize NVX-CoV2373 in Japan. Under the agreement, Takeda purchases the Company’s Matrix-M™ adjuvant to manufacture NVX-CoV2373 and the Company is entitled to receive payments from Takeda based on the achievement of certain development and commercial milestones, as well as a portion of net profits from the sale of NVX-CoV2373 in the low to middle double-digit range. During the three months ended June 30, 2022, the Company recognized a milestone payment of $20.0 million upon the first sale in Japan.

The Company has a collaboration and license agreement with SK bioscience Co., Ltd. (“SK bioscience”) to manufacture and commercialize NVX-CoV2373 for sale to the governments of South Korea, Thailand, and Vietnam. SK bioscience pays a royalty in the low to middle double-digit range. Additionally, the Company has a manufacturing supply arrangement with SK bioscience under which SK bioscience supplies the Company with the antigen component of NVX-CoV2373 for use in the final drug product globally, including product to be distributed by the COVAX Facility, which was established to allocate and distribute vaccines equitably to participating countries and economies. In July 2022, the Company signed an additional agreement with SK bioscience for the technology transfer of the Company’s proprietary COVID-19 variant antigen materials so that SK bioscience can manufacture the drug substance targeting COVID-19 variants, including the Omicron subvariants. The companies also signed an agreement to manufacture and supply the Novavax COVID-19 vaccine in a prefilled syringe.

On September 30, 2022, the Company, FUJIFILM Diosynth Biotechnologies UK Limited (“FDBK”), FUJIFILM Diosynth Biotechnologies Texas, LLC (“FDBT”), and FUJIFILM Diosynth Biotechnologies USA, Inc. (“FDBU” and together with FDBK and FDBT, “Fujifilm”) entered into a Confidential Settlement Agreement and Release (the “Fujifilm Settlement Agreement”) regarding amounts due to Fujifilm in connection with the termination of manufacturing activity at FDBT under the Commercial Supply Agreement (the “CSA”) dated August 20, 2021 and Master Services Agreement dated June 30, 2020 and associated statements of work (the “MSA”) by and between the Company and Fujifilm. The MSA and CSA established the general terms and conditions applicable to Fujifilm’s manufacturing and supply activities related to NVX-CoV2373 under the associated statements of work.

Pursuant to the Fujifilm Settlement Agreement, the Company is responsible for payment of up to $185.0 million (the “Settlement Payment”) to Fujifilm in connection with cancellation of manufacturing activity at FDBT under the CSA, of which (i) $47.8 million, constituting the initial reservation fee under the CSA, was credited against the Settlement Payment on September 30, 2022 and (ii) the remaining balance is to be paid in four equal quarterly installments of $34.3 million each beginning March 31, 2023. As of September 30, 2022, $102.9 million of the remaining payment was reflected in Accrued expenses and $34.3 million was reflected in Other non-current liabilities. Under the Fujifilm Settlement Agreement, Fujifilm is required to use commercially reasonable efforts to mitigate the losses associated with the vacant manufacturing capacity caused by the termination of manufacturing activities at FDBT under the CSA, and the final two quarterly installments will be mitigated by any replacement revenue achieved by Fujifilm between July 1, 2023 and December 31, 2023. The Settlement Payment is less than amounts previously recognized as embedded lease expense and reflected in Research and development expense from FDBT manufacturing activity under the CSA prior to the Fujifilm Settlement Agreement and accordingly, during the three and nine months ended September 30, 2022, the Company recorded a benefit of $98.3 million as Research and development expense (see Note 9).

Except with respect to certain limited activities agreed upon by the parties, the MSA terminated with respect to all activities in FDBU and FDBT on October 21, 2022 and the impact of the termination was determined in accordance with the provisions of the MSA. The terms and conditions of the MSA and CSA will remain in full force and effect with respect to the ongoing activities at FDBK. In addition, the Company and Fujifilm mutually released all claims relating to (i) the cancellation of batches to be manufactured at FDBT under the MSA or CSA, (ii) FDBT facility idle time in 2022, (iii) failure to complete product performance qualification testing of batches manufactured by Fujifilm by December 2021, and (iv) any obligation by Fujifilm to reserve capacity or manufacture batches at FDBT for the benefit of the Company under the MSA or CSA.
