**GAITHERSBURG, Md., November 6, 2025** – Novavax, Inc. (Nasdaq: NVAX) today announced its financial results and operational highlights for the third quarter ended September 30, 2025.

"We have continued the steady transformation of Novavax and are proud of our progress this quarter." said John C. Jacobs, President and Chief Executive Officer, Novavax. "This year we have relaunched the Company with a focus on R&D and partnerships intended to position us well for long-term growth and profitability."

**Third Quarter 2025 and Recent Highlights**

***Key Highlights***

***Strategic Priority #1: Optimize our Sanofi Partnership***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Continued successful execution of Sanofi partnership with $225 million in milestones earned year-to-date, including $50 million earned in the fourth quarter of 2025, upon marketing authorization transfers for E.U. and U.S. markets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In October 2025, Sanofi reported preliminary positive immunogenicity and safety Phase 1/2 data for Nuvaxovid™ in combination with both Fluzone High-Dose and Flublok. Both programs have received Fast Track designation from the U.S. Food and Drug Administration (FDA).

<br> <br> <br>

------

<br> <br> <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In August 2025, the FDA approved the Nuvaxovid 2025-2026 Formula for the prevention of COVID-19 in individuals 65 years of age and older, or 12 years through 64 years of age with at least one underlying condition that puts them at high risk for severe outcomes from COVID-19. Nuvaxovid was approved with an extended shelf life of six months in a pre-filled syringe formulation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Beginning in the third quarter of 2025, Sanofi assumed the lead commercial role for Nuvaxovid in the U.S. and select ex-U.S. markets for the 2025-2026 COVID-19 vaccination season.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In September 2025, Novavax expanded Sanofi's license to include use of Novavax's Matrix-M<sup>®</sup> adjuvant in Sanofi's pandemic influenza vaccine candidate program. Sanofi received funding from the Biomedical Advanced Research and Development Authority (BARDA) for early-stage clinical work on this vaccine candidate.

***Strategic Priority #2: Enhance Existing Partnerships and Leverage our Technology Platform and Pipeline to Forge Additional Partnerships***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In September 2025, our partner Takeda received approval of Nuvaxovid in Japan which triggered a milestone payment to Novavax.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• R21/Matrix-M, a malaria vaccine developed in partnership with Serum Institute of India and Oxford University, continued to make meaningful progress in addressing the urgent and unmet needs of malaria-endemic regions with 25 million doses sold since launch in mid-2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In the first quarter of 2025, Novavax announced material transfer agreements with three pharmaceutical companies to explore the utility of Matrix-M in their portfolios; discussions continue with these companies for the potential use of Matrix-M in the development of new vaccines and/or improve existing vaccines.

***Strategic Priority #3: Advance our Technology Platform and Early-Stage Pipeline***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Continued advancement of early-stage preclinical research for varicella-zoster virus (shingles), Clostridioides difficile colitis and respiratory syncytial virus combinations vaccine candidates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Pursuing government funding for pandemic influenza vaccine candidate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Continued exploration of our Matrix-M platform technology in oncology.

**Other Corporate Highlights**

------

<br> <br> <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In August 2025, Novavax completed a convertible debt refinancing; extending the maturity of the majority of the Company's existing 2027 Notes to 2031, with improved terms, and providing additional proceeds through the issuance of new 2031 Notes. This transaction further supports the financial strength of the company and its ability to execute on its long-term growth strategy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In October 2025, Novavax announced transactions to enable the planned consolidation of its Maryland based facilities in line with its corporate strategy. These transactions will result in $60 million in payments to Novavax and are expected to result in future cost savings of approximately $230 million over 11 years.

**Third Quarter 2025 Financial Results** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Total revenue** for the third quarter of 2025 was $70 million, compared to $85 million in the same period in 2024.

------

<br> <br> <br>

**Non-GAAP Financial Measures** 

The Company presents the following non-GAAP financial measures in this press release: Non-GAAP Combined R&D and SG&A Expenses, Adjusted Total Revenue and Adjusted Licensing, Royalties and Other Revenue. Non-GAAP financial measures refer to financial information adjusted from financial measures prepared in accordance with accounting principles generally accepted in the United States (GAAP). The Company believes that the presentation of these adjusted financial measures is useful to investors as they provide additional information on comparisons between periods by including certain items that affect overall comparability. The Company uses these non-GAAP financial measures for business planning purposes and to consider underlying trends of its business. Non-GAAP financial measures should be considered in addition to, and not as an alternative for, the Company's reported results prepared in accordance with GAAP. Our use of non-GAAP financial measures may differ from similar measures

------

<br> <br> <br>

reported by other companies and may not be comparable to other similarly titled measures. The Company is unable to reconcile these revenue forward-looking non-GAAP financial measures to the most directly comparable GAAP measures without unreasonable effort because the Company is reliant on Sanofi sales forecasts for certain revenue categories, which are not available.
