Item 7.01 Regulation FD Disclosure.

On August 13, 2025, Vaxart, Inc. (the “Company”) issued a press release announcing the Decision discussed below under Item 8.01. A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The information in this Item 7.01 and Exhibit 99.1 is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or subject to the liabilities of that section or Sections 11 and 12(a)(2) of the Securities Act of 1933, as amended. The information contained in this Item 7.01 and in the accompanying Exhibit 99.1 shall not be deemed incorporated by reference into any filing with the U.S. Securities and Exchange Commission made by the Company, whether made before or after the date hereof regardless of any general incorporation language in such filing.

Item 8.01 Other Events.

As previously reported, on July 2, 2024, the Company received a written notice from the Listing Qualifications Department (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that because the closing bid price for the Company’s common stock had fallen below $1.00 per share for 30 consecutive business days, it no longer complied with the minimum bid price requirement (the “Minimum Bid Price Requirement”) for continued listing under Nasdaq Listing Rule 5550(a)(2) on The Nasdaq Capital Market. The Company was provided until December 30, 2024, to regain compliance with the Minimum Bid Price Requirement, which was subsequently extended to June 30, 2025. On July 1, 2025, the Company received a written notification from the Staff of its determination to delist the Company’s common stock as a result of the Company’s ongoing failure to comply with the Minimum Bid Price Requirement, unless the Company were to timely request an appeal of its determination before the Nasdaq Hearings Panel (the “Panel”) by July 8, 2025. The Company timely requested a hearing before the Panel to appeal the delisting determination by the Staff. The Panel considered the Company’s appeal at a hearing held on August 14, 2025.

On August 27, 2025, the Panel issued a written decision (the “Decision”) to the Company and determined to grant the Company’s request to continue its listing on Nasdaq, subject to the following conditions:

1.	On or before September 5, 2025, the Company shall obtain shareholder approval for a reverse stock split (“RSS”);
2.	On or before October 6, 2025, the Company shall complete a RSS; and
3.	On or before October 17, 2025, the Company shall demonstrate compliance with the Minimum Bid Price Requirement.

The Decision noted that, if the Company fails to obtain approval of the RSS at the September 5, 2025 special meeting of stockholders, the Panel will delist the Company’s securities. It is a requirement during the exception period that the Company provide prompt notification of any significant events that occur during this time that may affect the Company’s compliance with Nasdaq requirements. The Decision noted that the Panel reserves the right to reconsider the terms of the exception based on any event, condition or circumstance that exists or develops that would, in the opinion of the Panel, make continued listing of the Company’s securities on Nasdaq inadvisable or unwarranted.

The Company was informed that the Nasdaq Listing and Hearing Review Council may, on its own motion, determine to review any Panel decision within 45 calendar days after issuance of the written decision. If the Listing Council determines to review this Decision, it may affirm, modify, reverse, dismiss or remand the decision to the Panel.
