SHAREHOLDER ACTION NOTICE: Faruqi & Faruqi, LLP Notifies Vistagen (VTGN) Investors of the Pending Class Action Lawsuit

Faruqi & Faruqi is a leading national securities law firm with offices in New York, Pennsylvania, California and Georgia. The firm has recovered hundreds of millions of dollars for investors since its founding in 1995. See www.faruqilaw.com.

As detailed below, the complaint alleges that the Company and its executives violated federal securities laws by making false and/or misleading statements and/or failing to disclose material adverse facts concerning its Phase 3 PALISADE-3 trial study of fasedienol, an investigational pherine candidate in development for the acute treatment of social anxiety disorder.

On December 17, 2025, before the market opened, Vistagen announced topline results from its PALISADE-3 Public Speaking Challenge Study of fasedienol for the acute treatment of social anxiety disorder (SAD). The company reported that the study failed to meet its primary efficacy endpoint since it "did not demonstrate statistically significant improvement on primary endpoint of reduction in anxiety as measured by SUDS scores compared to placebo."

On this news, Vistagen stock fell $3.50 or 80.27% to close at $0.86 on December 17, 2025.

The court-appointed lead plaintiff is the investor with the largest financial interest in the relief sought by the class who is adequate and typical of class members who directs and oversees the litigation on behalf of the putative class. Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member. Your ability to share in any recovery is not affected by the decision to serve as a lead plaintiff or not. 

Faruqi & Faruqi, LLP also encourages anyone with information regarding Vistagen's conduct to contact the firm, including whistleblowers, former employees, shareholders and others.
