Datavault AI Inc. investors who purchased securities between September 4, 2024, and October 30, 2025, are being notified by Rosen Law Firm about a pending securities class action and an October 5, 2026, lead plaintiff deadline. The lawsuit alleges that the company overstated the value of corporate partnerships involving Burke, Scilex and Nature’s Miracle, overstated trading activity on the Datavault Platform, and failed to disclose connections with Edward Withrow III, a convicted felon. DVLT shares dropped $0.49, or 19.44%, to close at $2.03 on October 31, 2025, after a research report questioned the platform’s activity and the value of data offered for sale. The existing case was filed in the United States District Court for the Eastern District of Pennsylvania under the Private Securities Litigation Reform Act of 1995. No class has been certified, and investors may remain absent class members without taking action. Those seeking lead plaintiff status must move the court by October 5, 2026; Rosen says eligible investors may participate without upfront fees or out-of-pocket costs under a contingency fee arrangement.
