CASE DETAILS: According to the Complaint, the Company made false and misleading statements to the market. Specifically, Defendants made false and/or misleading statements and/or failed to disclose that: (i) Defendants had overstated the size and nature of its announced “Center for AI and Quantum Computing Excellence”; (ii) Defendants had overstated the economic value to Datavault AI of its various corporate partnerships with, e.g., Scilex, Burke, and Nature’s Miracle; (iii) Defendants had overstated the status and volume of trading activity on the Datavault Platform, which was in fact minimal; (iv) Defendants had misrepresented the Company’s working capital and liquidity position, and the Company’s ability to continue as a going concern had not been alleviated; and (v) as a result, Defendants’ public statements were materially false and misleading at all relevant times. In addition, the Company suffered reputational harm when its ties to a convicted felon were revealed.

Based on these facts, the Company’s public statements were false and materially misleading throughout the class period. When the market learned the truth about Datavault AI through a series of disclosures from October 31, 2025 through August 18, 2026, investors suffered damages.
