Exhibit 99.1

May 5, 2025
Dear Vaxart, Inc. Stockholders:
We are writing to update you on recent developments that positively impact Vaxart’s ability to advance our promising vaccine candidates and highlight the importance of remaining listed on Nasdaq in order to maintain our progress. We would greatly appreciate your voting “FOR” the reverse stock split proposal to continue our momentum at this critical time.
Despite extreme volatility from macroeconomic disruption resulting in substantial challenges within the biotech sector, Vaxart has done a remarkable job navigating this environment and believes it remains well-positioned to transform global public health with oral pill vaccines.
Our Recent Progress
As indicated in our recently filed Form 8-K, a previously issued government stop work order was lifted on April 24, 2025, enabling the Company to continue the planned clinical trial of our promising COVID-19 vaccine candidate. This exciting development provides strong support for the important work we are doing and paves the way for continued nondilutive government funding. We are in active dialogue with BARDA and are moving quickly to screen and, upon receiving BARDA approval, enroll and dose participants for the 10,000 participant portion of our COVID-19 Phase 2b trial.
We are also making rapid progress with our norovirus program, having completed enrollment of all 60 participants in under two months. As recently announced, we remain on track to report topline data in mid-2025. This trial is an important next step in our norovirus development plan. Strategic partners are closely monitoring this upcoming data readout, and if the data prove our research thesis of an improved norovirus second generation construct, we believe it could lead to a partnership that would further advance the program and could provide further non-dilutive funding to the Company.
Our Strategy
Concurrently, in light of the challenging environment, we continue to take prudent measures to control costs in order to best position the Company for future success. Accordingly, we recently implemented another round of strategic cost reductions (including workforce reductions) that assisted in extending cash runway into 2026, allowing us to deliver on multiple potentially transformative data readouts in the above-mentioned programs. We will continue to balance cost savings and R&D investment to maximize Vaxart’s opportunities. We are also aggressively seeking additional sources of non-dilutive funding.
We recognize stockholders may be disappointed with Vaxart’s stock performance and acknowledge the frustration voiced by some who prefer we had issued a press release touting the stop work order being lifted. Our agreement with BARDA requires BARDA’s approval of any press release on BARDA-funded projects, and we do not control the timing of that approval. Due to SEC requirements, we are required to disclose such material developments and thus we were constrained to following legal requirements for disclosure by filing a Form 8-K.
Upcoming Opportunities to Follow Our Progress
We continue to believe Vaxart is a compelling investment opportunity, and we are dedicated to executing on the Company’s strategic plan to drive long-term value. We appreciate your support and value your input. To that end, we will be hosting a Q1 2025 earnings call on Tuesday, May 13,^^2025 to provide business updates and discuss Vaxart’s latest quarter. During the call, we will conduct a Q&A session to address stockholder questions.
Further reflecting our commitment to keep stockholders informed of Vaxart’s progress, we will be conducting a webcast of our presentation at Citizens Life Sciences Conference on May 7, 2025. Stockholders can access the webcast on the Company’s website at www.vaxart.com, and a replay of the presentation will be available for 30 days following the conclusion of the event.
Approval of Stock Split—An Important Part of Our Strategy that Needs Your Support
Vaxart’s annual meeting will be held on Wednesday, May 21, 2025, and your support would be greatly appreciated. Of particular importance is a proposal to provide the board of directors with the option, but not the requirement to implement a reverse stock split. The proposal is aimed at mitigating the risk of Vaxart being delisted from Nasdaq for failing to meet the exchange’s minimum bid price requirement of $1.00 per share. Recognizing this significant risk, both leading independent proxy advisors, Institutional Shareholder Services and Glass Lewis, have recommended stockholders vote “FOR” this important proposal.
The board of directors only intends to effect a reverse stock split if it is required to maintain a Nasdaq listing; and in the case that a reverse split is required, to select a ratio only high enough as it deems necessary to resolve the Nasdaq deficiency, taking into account the recent volatility of the stock market. Of course, we would prefer the requirement to be satisfied through appreciation of Vaxart’s stock price, and if we regain Nasdaq compliance in the required timeframe, the board of directors does not intend to effect a reverse stock split.
We believe it is critical that Vaxart have the option to implement a reverse stock split if necessary to avoid delisting. Delisting would severely impair Vaxart’s liquidity and could adversely affect the value of the securities that you hold and our trading volume, making it more difficult to buy and sell our securities. It might also hinder our ability to continue to fund important initiatives and explore strategic partnerships. We therefore would greatly appreciate your voting for this important proposal.
Thank you for your continued interest and support.
Sincerely,

Steven Lo
President & Chief Executive Officer
