Vaxart CEO Issues Letter to Stockholders

- Management Urges Stockholders to Vote FOR Reverse Stock Split Proposal by 11:59 p.m. Eastern Time on September 4, 2025 -

SOUTH SAN FRANCISCO, Calif., Aug. 08, 2025 (GLOBE NEWSWIRE) -- Vaxart, Inc. (OTCQX: VXRT) (鈥淰axart鈥� or the 鈥淐ompany鈥�), a clinical-stage biotechnology company developing a range of oral recombinant pill vaccines based on its proprietary delivery platform, today issued the following letter to its stockholders from its President & Chief Executive Officer, Steven Lo.

Dear Vaxart, Inc. Stockholders:

We deeply appreciate your continued support and commitment to Vaxart鈥檚 mission. Many of you have stood by us through both exciting breakthroughs and challenging moments, and we want to acknowledge that journey as we provide an important update on our efforts to relist Vaxart鈥檚 common stock on Nasdaq.

Why Relisting Matters

We understand that some stockholders鈥攑articularly those who have been with us for years鈥攎ay feel frustrated by the current share price and are skeptical about another reverse stock split proposal. We hear you and we share that frustration. We have worked hard to advance our science and will continue to make every effort to create value for our stockholders. But we also want to be transparent about why regaining our Nasdaq listing is a strategic imperative for Vaxart鈥檚 future and will ultimately maximize long-term value for all stockholders.

Being listed on Nasdaq offers critical advantages that directly impact our ability to continue to advance toward developing and commercializing our products, making Vaxart and our vaccines more valuable to potential non-dilutive, strategic and other investors and ultimately giving us the best chance to see share price appreciation. Nasdaq listing provides:

• Broader Access to Investors: Many institutional investors and life sciences funds are restricted from investing in OTC-listed stocks or those trading below $1. Likewise, some brokerage platforms limit access to OTC-listed stocks for retail investors. A Nasdaq listing expands the pool of potential investors鈥攔etail and institutional alike.
  
  
• Greater Visibility and Analyst Coverage: Most sell-side analysts do not cover OTC-listed stocks. Relisting would increase the likelihood of analyst coverage, which can enhance market visibility and help all investors make more informed decisions.
  
  
• Enhanced Financial Flexibility: Drug development is capital intensive. While we are grateful for BARDA鈥檚 support, recent events such as the Stop Work Order the Company has received demonstrate that we must rely on multiple sources for funding, allowing us to be prepared for regulatory shifts or opportunities to accelerate promising programs. A Nasdaq listing improves our ability to secure financing on more favorable terms鈥攈elping to protect long-term value and reduce dilution risk.
  
  
• Improved Market Perception: Nasdaq is home to many of the world鈥檚 most respected biotech companies. Relisting would reaffirm our position as a serious innovator in vaccine science and offer greater transparency, liquidity, and stability for all investors.
  
  
• Stronger Partnership Positioning: A Nasdaq listing provides credibility and leverage in negotiations, which enhances our position as we explore collaborations to accelerate our pipeline.
  
  

Additionally, we believe the enhanced liquidity and rigorous rules of Nasdaq help protect stockholder interests and could weigh favorably on stock price.

Reverse Stock Split Proposal

We recognize that reverse stock splits are often met with concern, especially among retail investors. Let us be clear: we do not take this decision lightly. We share in the disappointment that the share price has remained below the Nasdaq minimum bid price even when no reverse split proposal was effected. Given our current valuation and absent substantial near-term appreciation, a reverse stock split remains the most viable path to relist on Nasdaq.

We have appealed Nasdaq鈥檚 suspension and are scheduled to meet with their hearings panel on August 14, 2025. But based on our discussions and the realities of the market, we believe relisting is contingent on conducting a reverse stock split.

Importantly, this proposal includes a significantly narrower split ratio and a proportionally reduced authorized share count to minimize dilution. And while reverse splits may feel disruptive, they do not change the fundamental value of your investment鈥攋ust the number of shares you hold. Think of it as exchanging four five-dollar bills for one twenty-dollar bill.

Finally, this proposal will have an equal impact on our employees, management and directors. The reverse stock split, per our plan documents, will be consistently applied to all common equity, including option holdings, option exercise prices and share holdings, as well as the pool of shares available for future grants. We believe this aligns managements interest in share price appreciation with your interests.

Your Voice Matters

We are asking stockholders to approve this proposal at our Special Meeting of Stockholders on September 5, 2025. We know this is a consequential vote, and we want to ensure you feel heard.

To that end, we鈥檝e scheduled a Stockholder Fireside Chat on August 20, 2025 at 4:30 p.m. ET. You can submit questions in advance to [email protected] or participate live via webcast. We鈥檒l share more details soon.

Scientific Progress and Milestones

While we deem re-listing on Nasdaq essential to Vaxart鈥檚 market position, our core mission remains unchanged: to advance transformative oral vaccines that improve global health. We鈥檙e proud to share recent progress:

• COVID-19 Oral Vaccine: Our Phase 2b trial has enrolled rapidly, and we have successfully enrolled approximately half of the anticipated 10,000 participants before receiving the most recent stop work order. While we work to determine next steps in this study and remain in dialogue with our government partners, we believe that with more than 5,000 enrolled participants our data will be very comprehensive. Topline data is anticipated in late 2026.
  
  
• Norovirus Vaccine: We announced positive Phase 1 results for our second-generation oral pill constructs, showing stronger antibody responses and excellent safety. Discussions for a Phase 2 partnership are ongoing.
  
  
• Avian Influenza Candidate: Our preclinical vaccine showed 100% protection in a robust ferret challenge model. Full results will be published upon completion of our analysis.
  
  

We鈥檝e also taken steps to extend our cash runway into 2026, implementing cost reductions while preserving our ability to deliver multiple data readouts.

Thank You

We know this has been a challenging period, and we are grateful for your continued belief in Vaxart鈥檚 vision. We remain committed to transparency, scientific excellence, and creating long-term value for all stockholders鈥攔etail and institutional alike.

We hope you will join us in supporting this critical proposal and continuing the journey toward a stronger, more visible, and more impactful Vaxart.

Sincerely,
Steven Lo
President & Chief Executive Officer
