Rosen Law Firm is reminding investors who purchased Datavault AI Inc. securities 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 an existing securities class action. Eligible investors may pursue compensation through a contingency-fee arrangement without paying out-of-pocket fees or costs, according to the notice. The lawsuit alleges that Datavault AI defendants overstated the economic value of corporate partnerships with Burke, Scilex and Nature’s Miracle; overstated trading activity on the Datavault Platform; and failed to disclose connections with Edward Withrow III, described in the lawsuit as a convicted felon. The complaint says those matters caused the company’s public statements to be materially false or misleading. No class has been certified, and investors may choose their own counsel, remain absent class members or take no action for now. The notice says an investor’s ability to share in any potential recovery does not depend on serving as lead plaintiff.
