Forward-looking Statements

This press release contains certain forward-looking statements within the meaning of the federal securities laws, including, without limitation, statements regarding Vistagen’s beliefs about the significance of achieving minimum patient exposure recommendations referenced in the ICH E1 guidance; the favorable safety and tolerability data of fasedienol observed to date; the potential implications of data collected from Vistagen’s PALISADE Phase 3 clinical development program for fasedienol; the expected timing of topline results from the randomized portion of PALISADE-4 and the Repeat Dose Study; Vistagen’s plans to generate additional evidence to support the clinical meaningfulness of the duration and magnitude of effect of fasedienol; and Vistagen’s belief that successful results from its PALISADE Phase 3 development program, including PALISADE-4, could provide substantial evidence of fasedienol’s effectiveness in support of a potential U.S. NDA submission to the FDA. These forward-looking statements involve known and unknown risks that are difficult to predict and include all matters that are not historical facts. In some cases, you can identify forward-looking statements by the use of words such as “may,” “could,” “expect,” “project,” “outlook,” “strategy,” “intend,” “plan,” “seek,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “strive,” “goal,” “continue,” “likely,” “will,” “would” and variations of these terms and similar expressions, or the negative of these terms or similar expressions. Such forward-looking statements are necessarily based upon estimates and assumptions that, while considered reasonable by Vistagen and its management, are inherently uncertain. As with all pharmaceutical products, there are substantial risks and uncertainties in the process of development and commercialization, and actual results or developments may differ materially from those projected or implied in these forward-looking statements. There can be no guarantee that any of Vistagen’s product candidates, including fasedienol, will successfully complete ongoing or future clinical trials within estimated timelines or at all, receive regulatory approval or be commercially successful. In addition, achievement of patient exposure levels referenced in ICH E1 does not establish that the FDA will determine Vistagen’s safety database is sufficient to support a potential U.S. NDA submission or regulatory approval. Other factors that may cause such a difference include, without limitation, risks and uncertainties relating to conducting and/or completing ongoing clinical trials, including those that are a part of Vistagen’s fasedienol PALISADE Phase 3 program, as currently expected or at all; Vistagen’s ability to ability to successfully employ cash preservation measures and/or secure adequate financing for its operations, including financing or collaborative support for continued clinical development of its product candidates; Vistagen's dependence on third-party collaborators for the development, regulatory approval, and/or commercialization of its product candidates and other aspects of its business, which are outside of Vistagen's full control; the scope and enforceability of Vistagen’s patents, including patents related to Vistagen’s pherine product candidates; and other technical and unexpected hurdles in the development, manufacture and/or potential commercialization of Vistagen’s product candidates. These risks and others are more fully discussed in the section entitled “Risk Factors” in Vistagen’s Quarterly Report on Form 10-Q for the period ended December 31, 2025, as well as discussions of potential risks, uncertainties, and other important factors in our other filings with the U.S. Securities and Exchange Commission (SEC). Vistagen’s SEC filings are available on the SEC’s website at www.sec.gov. You should not place undue reliance on these forward-looking statements, which apply only as of the date of this press release and should not be relied upon as representing Vistagen’s views as of any subsequent date. Vistagen explicitly disclaims any obligation to update any forward-looking statements other than as may be required by law. If Vistagen does update one or more forward-looking statements, no inference should be made that Vistagen will make additional updates with respect to those or other forward-looking statements.
