Forward-looking statements involve estimates, assumptions, risks, and uncertainties that could cause actual results or outcomes to differ materially from those expressed or implied in any forward-looking statements, and, therefore, you should not place considerable reliance on any such forward-looking statements. Such risks and uncertainties include, without limitation, challenges or delays in obtaining regulatory authorization for its COVID-19 vaccine, in particular with respect to its BLA submissions to the FDA for approval of its COVID-19 vaccine, or its product candidates, including for future COVID-19 variant strain changes, its CIC vaccine candidate, its stand-alone influenza vaccine candidate or other product candidates; Novavax's ability to successfully and timely manufacture, market, distribute, the impact of its not having received a BLA from the FDA for the 2024-2025 vaccination season; challenges related to Novavax's partnership with Sanofi and in pursuing additional partnership opportunities; challenges satisfying, alone or together with partners, various safety, efficacy, and product characterization requirements, including those related to process qualification, assay validation and stability testing, necessary to satisfy applicable regulatory authorities; challenges or delays in conducting clinical trials or studies for its product candidates; manufacturing, distribution or export delays or challenges; Novavax's substantial dependence on Serum Institute of India Pvt. Ltd. and Serum Life Sciences Limited for co-formulation and filling Novavax's COVID-19 vaccine and the impact of any delays or disruptions in their operations; difficulty obtaining scarce raw materials and supplies including for its proprietary adjuvant; resource constraints, including human capital and manufacturing capacity; constraints on Novavax's ability to pursue planned regulatory pathways, alone or with partners; challenges in implementing its global restructuring and cost reduction plan; Novavax's ability to timely deliver doses; challenges in obtaining commercial adoption and market acceptance of its COVID-19 vaccine or any COVID-19 variant strain containing formulation, or for its CIC vaccine candidate and stand-alone influenza vaccine candidate or other product candidates; challenges meeting contractual requirements under agreements with multiple commercial, governmental, and other entities, including requirements to deliver doses that may require Novavax to refund portions of upfront and other payments previously received or result in reduced future payments pursuant to such agreements and challenges in amending or terminating such agreements; challenges related to the seasonality of vaccinations against COVID-19 or influenza; challenges related to the demand for vaccinations against COVID-19 or influenza; challenges in identifying and successfully pursuing innovation expansion opportunities, including with respect to Novavax's Matrix-M<sup>TM</sup> adjuvant; Novavax's expectations as to expenses and cash needs may prove not to be correct for reasons such as changes in plans or actual events being different than its assumptions; and other risks and uncertainties identified in Part I, Item 1A "Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the Securities and Exchange Commission ("SEC") on February 27, 2025, and in our subsequent quarterly reports on Form 10-Q, which may be modified or updated in other documents filed with the SEC from time to time, and are available at www.sec.gov and at www.novavax.com.

**Novavax's COVID-19-Influenza Combination and Stand-alone Influenza Vaccine Candidates Showed Robust Immune Responses and Were Well Tolerated in Initial Cohort of a Phase 3 Trial**

&nbsp;&nbsp;&nbsp;&nbsp;· *Both vaccine candidates induced robust immune responses across all antigens tested* 

· *No new safety signals were observed and both vaccine candidates were well tolerated consistent with past trials* 

· *Novavax continues to pursue partnering opportunities to advance further development of these programs* 

**GAITHERSBURG, Md., June 11, 2025 –** Novavax, Inc. (Nasdaq: NVAX) today announced results of the initial cohort of its COVID-19-Influenza Combination (CIC) and stand-alone trivalent hemagglutinin nanoparticle seasonal influenza (tNIV) Phase 3 trial that showed both the CIC and flu vaccine candidates induced immune responses similar to licensed comparators Nuvaxovid<sup>®</sup> and Fluzone HD, respectively. This cohort was designed to provide descriptive data on three flu strains (H1N1, H3N2, B) and SARS-CoV-2 (COVID-19) to inform a future registrational Phase 3 program.

"Both our combination and stand-alone flu vaccine candidates induced robust immune responses and were well tolerated," said Ruxandra Draghia-Akli, MD, PhD, Executive Vice President and Head of Research and Development, Novavax. "This data set adds to findings from our Phase 2 trial and will help inform discussions with potential partners."

Both stand-alone flu and CIC vaccine candidates induced robust immune responses to the vaccine strains (2.4-5.7-fold over baseline). Both vaccine candidates were well tolerated and saw reactogenicity comparable to authorized comparators. Nearly all (>98%) solicited adverse events were mild or moderate in severity.

![](tm2517661d1_ex99-1img002.jpg)

This descriptive trial was designed to evaluate the safety and immunogenicity of the CIC and stand-alone flu vaccine candidates compared to Nuvaxovid and Fluzone HD in approximately 2,000 adults aged 65 and older. This trial was not adequately powered to demonstrate statistical significance. These results build on previous <u>Phase 2 data</u>.

Observations from Initial Cohort of CIC - 301 Study • Both stand - alone flu and CIC vaccine candidates induced robust immune responses to the vaccine strains (2.4 - 5.7 - fold over baseline). • Both vaccine candidates were well tolerated . Nearly all (>98%) solicited adverse events were mild or moderate in severity. Endpoints of neutralizing antibody responses and safety were not powered to formally assess noninferiority STUDY OBSERVATIONS
