Moody Capital Solutions, Inc. to act as dealer manager of a rights offering open to all shareholders of the company

Datavault AI Inc. (NASDAQ:DVLT) ("Datavault AI" or the "Company"), an Artificial Intelligence Platform ("AIP") company providing data monetization, credentialing and tokenization technologies, today announced that its board of directors (the "Board") has approved a rights offering to holders of its common stock ("Common Stock") and certain other Datavault AI securities. Moody Capital Solutions, Inc. ("Moody Capital") will act as dealer manager for the rights offering.

The Rights Offering to include investors in a process usually reserved exclusively for banks

Under the rights offering, the Company will distribute, at no charge, transferable subscription rights to holders of record of Common Stock and certain other Company securities with a contractual right to participate in the distribution. The Company has set a record date of October 9, 2026 for such offering (the "Record Date"). Such holders will receive one subscription right for a Common Unit for each share of Common Stock owned as of the Record Date and one subscription right for a Preferred Unit for each 100 shares of Common Stock owned as of the Record Date.

Common Units. Each Common Unit will consist of (i) one share of Common Stock, (ii) one Series A Right to purchase one share of Common Stock (the "Series A Right") and (iii) one Series B Right to purchase one share of Common Stock (the "Series B Right"). The subscription price of each Common Unit will be $0.20. The Series A Right will be exercisable at $0.25 per share and will expire six months from the closing of the rights offering. The Series B Right will be exercisable at $0.30 per share and will expire twelve months from the closing. The Company expects to offer up to $50,000,000 of Common Unit subscription rights.

Preferred Units. Each Preferred Unit will consist of (i) one share of a newly designated series of preferred stock ("Preferred Stock"), (ii) one Series 1 Right to purchase one share of Preferred Stock (the "Series 1 Right") and (iii) one Series 2 Right to purchase one share of Preferred Stock (the "Series 2 Right"). The subscription price of each Preferred Unit will be $25.00. The Series 1 Right will be exercisable at $30.00 per preferred share and will expire six months from the closing of the rights offering. The Series 2 Right will be exercisable at $35.00 per preferred share and will expire twelve months from the closing. The Preferred Stock will carry a stated value and liquidation preference of $25.00 per share and will rank senior to the Common Stock. It will pay a cumulative dividend of $2.10 per share per annum, payable semi-annually in arrears (a) in cash, (b) at the Company’s election, in additional shares of the same series, or (c) at the Company’s election, in common stock at a 10% discount to market, subject to a floor price and an aggregate cap, as will be described in the prospectus supplement for the Rights Offering. The Company intends to apply to list the Preferred Stock on the Nasdaq Capital Market and to seek a listing or quotation for the Common Unit subscription rights, Preferred Unit subscription rights, Series A Rights, Series B Rights, Series 1 Rights and Series 2 Rights, although no assurance can be given that any listing will be obtained. The Preferred Stock will not be convertible into Common Stock. The Preferred Stock will vote together with the Common Stock as a single class on all matters submitted to a vote of stockholders, with the number of votes per preferred share to be fixed at execution of the dealer manager agreement by reference to the number of shares of Common Stock that $25.00 would then purchase. The Company expects to offer up to 3,000,000 Preferred Units, representing up to $75,000,000 of Preferred Unit subscription rights.

The Company’s stockholders and holders of certain other Company securities with a contractual right to participate in the distribution who exercise their respective full basic subscription rights will have over-subscription privileges, applied separately to the Common Units and the Preferred Units, giving such holders the option to subscribe for any Common Units and Preferred Units that remain unsubscribed at the expiration of the rights offering. If the aggregate subscriptions (basic subscriptions plus over-subscriptions) exceed the amount offered in the rights offering, then the aggregate over-subscription amount will be pro-rated among the holders exercising their respective over-subscription privileges based on the basic subscription amounts of such holders. The subscription rights are expected to be transferable.

The Company expects that the subscription period will be approximately 18 trading days from the commencement of the offering, subject to the Board’s right to extend the subscription period. The Company intends to use the net proceeds of the rights offering for working capital and general corporate purposes, which may include funding potential strategic transactions, acquisitions or investments.

Datavault AI raises the bar in Digital Assets and continues to vault forward."

Owning digital asset exchanges, building them up to solve problems using AI and blockchain makes this a really exciting time for all of us not just to own it but to get involved in the token economy."
