&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Reiterates 2026 Revenue Framework and Combined R&D and SG&A expense guidance* 

**GAITHERSBURG, Md., May 6, 2026** – Novavax, Inc. (Nasdaq: NVAX) today announced its financial results and operational highlights for the first quarter ended March 31, 2026.

"Novavax continued to make significant progress executing our corporate strategy which is comprised of partnering our technology, capital-efficient R&D innovation and a lean operating platform. In 2026, we signed a new, Matrix-M license with Pfizer for up to two vaccine candidates and secured four additional MTAs with a growing list of large pharmaceutical and innovative biotech companies," said John C. Jacobs, President and Chief Executive Officer, Novavax. "With these agreements in place, our partners have the right to evaluate Matrix in over 30 unique fields of experimentation targeting more than 50% of the projected over $100B market for infectious disease and oncology vaccines and immuno-therapeutics. In addition, Novavax continued to advance our own R&D efforts with the selection of our C. difficile vaccine candidate as our next potential asset to advance to the clinic as early as 2027."

**First Quarter 2026 and Recent Highlights**

***Key Business Highlights***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In January 2026, Novavax entered into a license agreement with Pfizer for use of Novavax's Matrix-M adjuvant in vaccine development. Under the terms of the agreement, Pfizer was granted a non-exclusive license for Matrix-M use in two infectious disease areas.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Novavax received an upfront payment of $30 million in the first quarter of 2026 and has the potential for up to $500 million in additional development and sales milestones. In addition, Novavax is eligible to receive high-mid-single digit percentage royalties on sales from products incorporating Matrix-M.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Pfizer will be solely responsible for the development and commercialization of its products utilizing Matrix-M, and Novavax will be responsible for the supply of Matrix-M.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ This partnership has the potential to generate billions of dollars of revenue for Novavax over the life of the agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In 2026, Novavax continued to expand its Matrix-M partnering efforts with global pharmaceutical companies and innovative biopharma companies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ In April, Novavax signed a new material transfer agreement (MTA) with a top ten global pharmaceutical company who is also a global leader in oncology to explore Matrix-M in a broad array of oncology targets, as well as antibiotic resistant bacterial infections and other infectious diseases.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ In April, Novavax signed a new MTA with an existing pharmaceutical partner for evaluation of Matrix-M in nine additional, identified disease areas.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ In February, Novavax expanded an existing MTA with a major global pharmaceutical company to explore an additional field and signed a new MTA with an innovative oncology company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In total, Novavax now has MTA collaborations and/or license agreements with four of the top ten global pharmaceutical companies and a number of innovative biotech companies who, collectively, have the right to explore Matrix-M in over 30 unique fields of experimentation across both infectious diseases and oncology.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ The goal of our MTA collaborations is to enable exploration of Matrix-M with the intent of entering into deeper partnership via formal license agreements, that in turn results in the advancement of partner's R&D clinical work toward the potential commercialization of innovative vaccines.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ The broad utility of our technology has resulted in several companies exploring Matrix-M for application in the same high-potential markets, including infectious disease areas such as cytomegalovirus, Epstein-Barr Virus, pneumococcal, and RSV; and also includes overlap in oncology areas such as colorectal cancer, head and neck cancer and pancreatic cancer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Existing partners under license and MTA agreements, have the right to address fields of experimentation that cover over 50% of the global market opportunity for infectious disease and oncology vaccines and immunotherapeutics, which is projected to grow to over $100 billion by the early 2030s.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In April, Sanofi announced positive Phase 4 results from the COMPARE study, a head-to-head study showing that Nuvaxovid demonstrated statistically significant lower side effects compared to Moderna's mNEXSPIKE across all pre-specified endpoints, reinforcing Nuvaxovid's well-established and differentiated reactogenicity profile ahead of the fall season.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Continued to progress Novavax R&D innovation in support of our growth strategy

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Clostridioides difficile colitis (C. difficile) vaccine candidate prioritized as potential next asset to enter the clinic as early as 2027.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Preliminary preclinical data generated by Novavax on its varicella-zoster virus (shingles) and respiratory syncytial virus early-stage assets were positive and provide path forward for informing the Company's future antigen design and adjuvant work.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ongoing adjuvant research is intended to expand the utility of our technology by creating new adjuvants tailored to foster specific differentiated immune properties for certain diseases that may require unique immune responses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Novavax continued to progress its cost reduction program to create a more lean and agile organization.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Targeting full year Non-GAAP combined R&D and Selling, General and Administrative (SG&A) expenses of $325 million for full year 2026 and $225 million for full year 2027, each period at the midpoint of the guidance range.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Improving the 2028 target for full year Non-GAAP combined R&D and SG&A expenses to between $150 million and $200 million. This reflects an anticipated expense reduction of over $200 million and over 50% when compared to full year 2025.

**First Quarter 2026 Total Revenue** 

First quarter 2025 Nuvaxovid sales included $603 million of non-cash sales related to the close-out of two APA agreements.

*Notes* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.*Nuvaxovid Sales reflects product sales where Novavax is the commercial market lead and records revenue related to the sales and distribution of its COVID-19 vaccine.* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.*Supply Sales includes sales of finished product, adjuvant and other supplies from Novavax to its license partners.*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.*Sanofi includes revenue recognized under the license agreement including upfront payments, milestones, royalties and transition services reimbursement.*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.*Other Partners include upfront payments, royalties and milestone revenue under licensing agreements including Takeda and SK bioscience.* 

**First Quarter 2026 Financial Results** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Total revenue** for the first quarter of 2026 was $140 million, a 79% decrease compared to $667 million in the same period in 2025. Higher Nuvaxovid™ product sales for the first quarter of 2025 were primarily due to $603 million of non-cash sales revenue recognized with the close-out of two Advance Purchase Agreements (APA). Licensing Royalty and Other revenue of $97 million in the first quarter of 2026 included $30 million related to the Pfizer Matrix-M agreement signed in January 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Cost of sales** for the first quarter of 2026 was $31 million, compared to $14 million in the same period in 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Research and development (R&D) expenses** for the first quarter of 2026 were $95 million, compared to $89 million in the same period in 2025. The higher R&D costs were primarily associated with COVID-19 postmarketing commitment studies and annual strain change activities. R&D expenses reimbursed by partners in the first quarter of 2026 were $28 million. Non-GAAP R&D expenses,

------

net of partner reimbursement, were $68 million in the first quarter of 2026, a 13% decrease when compared to $78 million in the same period in 2025. The lower Non-GAAP R&D expenses were driven by the ongoing Novavax cost reduction program as it streamlines operations to make targeted R&D investments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Selling, General and Administrative (SG&A) expenses** for the first quarter of 2026 were $29 million, a 40% decrease compared to $48 million for the same period in 2025. The decrease was primarily due to the transition of lead commercial activities to Sanofi and the elimination of commercial infrastructure plus the ongoing general administrative cost reduction program.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Net Loss** for the first quarter of 2026 was $9 million, compared to net income of $519 million in the same period in 2025. First quarter of 2025 net income benefited from $603 million of non-cash sales related to the close-out of two APA agreements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Cash, cash equivalents, marketable securities and restricted cash (Cash)** were $795 million as of March 31, 2026, compared to $751 million as of December 31, 2025. In February 2026, Novavax announced a $330 million credit facility with MidCap Financial, including an initial capital draw of $50 million. The credit facility was put in place to further strengthen Novavax's balance sheet and provide access to non-dilutive capital as Novavax advances its growth strategy.

**Financial Framework** 

**Reiterates Full Year 2026 Financial Guidance** 

Novavax reiterates its Full Year 2026 Financial Guidance for Combined R&D and SG&A Expenses and Non-GAAP Combined R&D and SG&A Expenses and expects to achieve the following results:

Please visit novavax.com and LinkedIn for more information.

**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 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.

**Forward-Looking Statements**
