Rosen Law Firm is reminding investors who purchased Datavault AI Inc. securities under the Nasdaq ticker DVLT between September 4, 2024, and October 30, 2025, inclusive, that October 5, 2026, is the deadline to ask the court to serve as lead plaintiff in a filed securities class action. The lawsuit alleges that Datavault AI overstated the economic value of corporate partnerships, trading activity on its platform and omitted connections with Edward Withrow III, a convicted felon. Investors may seek information or participate without paying upfront fees or costs under a contingency fee arrangement. No class has been certified, and investors may retain counsel, remain absent class members or take no action; eligibility for any potential future recovery does not depend on serving as lead plaintiff.
