WHO IS AFFECTED: Those who purchased Datavault AI securities between September 4, 2024 and October 30, 2025 may be entitled to recover damages.

DVLT closed at $2.03 on October 31, 2025, down $0.49 per share, or 19.44%, in a single session. The complaint recounts that insiders sold 38,065,752 shares for more than $73.8 million in proceeds during the Class Period.

September 4, 2024 — The $210 Million IP Acquisition Announcement

The Class Period opens with a press release announcing the agreement to acquire Data Vault Holdings intellectual property for $210 million, including the Datavault Platform, which was described as creating value through "scarcity, utility, and encrypted data protection." As detailed in the action, the announcement omitted the prior SEC charges against the incoming chief executive and his patent co-inventor's felony conviction for false statements tied to a pump and dump scheme.

July 22, 2025 through October 28, 2025 — The Partnership Cascade

Three partnerships were announced in succession. The complaint alleges that these initiatives were presented to the market as near-term revenue opportunities, but were later challenged as lacking the commercial substance investors had been led to expect.

Chronology of Material Events

• September 4, 2024: $210 million Data Vault Holdings IP acquisition announced; leadership regulatory history allegedly omitted.
• February 13, 2025: Name changed from WiSA Technologies to Datavault AI.
• July 9, 2025: A $250 million shelf registration statement declared effective by the SEC.
• July 22, 2025: Burke Products partnership announced as delivering 2025 revenues from subcontracted existing contracts, citing a U.S. defense budget expected to surpass $900 billion.
• September 25, 2025: A $150 million strategic investment from Scilex Holding Company announced, structured in tranches of $8,067,000 and $141,933,000.
• October 28, 2025: Nature's Miracle license announced with a $2 million non-refundable fee and a 35 percent royalty.
• October 31, 2025: Wolfpack Research report published; shares closed at $2.03.

October 31, 2025 — The Warning Signs Multiplied at Once

The Wolfpack Research report alleged that Scilex reported only $4.1 million in cash and cash equivalents against the $150 million commitment, and that Nature's Miracle reported only $9,511 in cash before agreeing to a $2 million fee. The report further alleged that Burke had never been awarded more than $4.5 million in contracts in any year since 2002, with contracts covering hoses, piping, fuses and electrical connectors. As alleged, trading activity on the Datavault Platform "appears to be minimal, if not non-existent," with listed data including celebrity photographs and widely available historical weather data.

"Timely disclosure of material developments is fundamental to fair and efficient markets. The sequence alleged here, in which partnership announcements were followed months later by public questions about the counterparties' ability to fund those commitments, raises serious issues for shareholders." -- Joseph E. Levi, Esq.

Those wishing to serve as lead plaintiff must act by October 5, 2026. The case is pending in the United States District Court for the Eastern District of Pennsylvania.

Frequently Asked Questions About the DVLT Lawsuit

Q: What specific misstatements does the DVLT lawsuit allege? A: The complaint alleges Datavault AI made materially false or misleading statements regarding the economic value of its partnerships with Burke Products, Scilex, and Nature's Miracle, the volume of trading activity on the Datavault Platform, and undisclosed leadership regulatory and criminal affiliations. When the October 31, 2025 short report challenged these claims, the stock price declined sharply.

Q: When did Datavault AI Inc. allegedly mislead investors? A: The Class Period runs from September 4, 2024 to October 30, 2025. The complaint alleges that corrective disclosures revealed information that caused a significant stock decline.

Q: How much did DVLT stock drop? A: Shares fell approximately 19.44%, a decline of $0.49 per share, closing at $2.03 on October 31, 2025, after publication of a research report challenging the Company's partnership claims and platform activity. Investors who purchased during the Class Period at allegedly inflated prices may be eligible to seek compensation.

Q: What court was the DVLT class action filed in? A: The case was filed in the United States District Court for the Eastern District of Pennsylvania, governed by the Private Securities Litigation Reform Act of 1995.

Q: What do DVLT investors need to do right now? A: Investors may gather brokerage records showing purchase dates, share quantities, and prices paid.

No immediate action is required to remain eligible as an absent class member.

Q: What is a lead plaintiff and why does it matter? A: A lead plaintiff is the investor appointed by the court to represent the entire class. Lead plaintiffs are typically investors with the largest documented losses. Being appointed does not increase individual recovery but gives direct oversight of how the case is run.

Q: What if I already sold my DVLT shares -- can I still recover losses? A: Yes. Eligibility is based on when you purchased, not whether you still hold the shares. Investors who bought during the Class Period and sold at a loss may still be eligible to participate.

Q: What does it cost me to participate? A: There is no upfront cost to contact the firm. Securities class actions are generally handled on a pure contingency basis, with no retainer and no out-of-pocket costs. Any attorneys' fees and expenses awarded to class counsel are subject to court approval.

Q: Do I need to go to court or give testimony? A: No. The overwhelming majority of class members never appear in court or give depositions. If there is a settlement or recovery, eligible class members generally submit a claim form to seek their portion.
