The Biconomy Resale SPA Shares were sold for a purchase price of $16.00 per share, payable in Bitcoin blockchain ("Bitcoin"), with such amount of Bitcoin equal to the quotient of (A) Biconomy's aggregate purchase price divided by (B) the spot exchange rate for Bitcoin as published by Coinbase.com at 8:00 p.m. (New York City time) on the trading day immediately prior to the closing date of the purchase of the Biconomy Resale SPA Shares. The closing of the transactions contemplated by the Biconomy Resale SPA occurred on September 25, 2025. The Bitcoin proceeds from sale of the Biconomy Resale SPA Shares were used to fund the acquisition of the Issuer's securities.

The information set forth in Item 3 is incorporated herein by reference. Datavault Securities Purchase Agreement On September 25, 2025, SHC entered into a Securities Purchase Agreement (the "Datavault SPA") with Datavault AI Inc., a Delaware corporation ("Datavault"), pursuant to which Datavault agreed to issue and sell, and SHC agreed to purchase, 15.0 million shares of Common Stock and a pre-funded warrant (the "Pre-Funded Warrant") to purchase 263,914,094 shares of Common Stock for an aggregate purchase price of $150 million. Pursuant to the Datavault SPA, on the initial closing date of September 26, 2025 (the "Initial Datavault Closing Date"), Datavault issued 15.0 million shares of Common Stock to SHC, for a per share purchase price of $0.5378 (the "Per Share Purchase Price"), to be paid in Bitcoin, with the amount of Bitcoin being based on the spot exchange rate for Bitcoin as published by Coinbase.com at 8:00 p.m. (New York City time) on the trading day immediately prior to the Initial Datavault Closing Date. Within 25 days of the Initial Datavault Closing Date, Datavault is required to, among other things, file with the Securities and Exchange Commission a preliminary proxy statement for the purpose of obtaining the Stockholder Approval (as defined below) and shall use its reasonable best efforts to solicit its stockholders' approval of such resolution. Datavault is also required to hold an annual or special meeting of its stockholders (the "Stockholder Meeting") for purposes of obtaining the Stockholder Approval no later than 75 days after the Initial Datavault Closing Date (the "Stockholder Meeting Deadline") and is obligated to obtain the Stockholder Approval by the Stockholder Meeting Deadline. If, despite Datavault's reasonable best efforts, the Stockholder Approval is not obtained on or prior to the Stockholder Meeting Deadline, Datavault shall cause an additional Stockholder Meeting to be held within 45 days thereafter. If, despite Datavault's reasonable best efforts the Stockholder Approval is not obtained after such subsequent stockholder meeting, Datavault shall cause an additional Stockholder Meeting to be held every fourth month thereafter until such Stockholder Approval is obtained. As used in the Datavault SPA, "Stockholder Approval" means (i) such approval as may be required by the applicable rules and regulations of the trading market from the stockholders of Datavault with respect to the transactions contemplated by the transaction documents, including with respect to issuance of all of the Pre-Funded Warrant Shares (as defined below) upon the exercise thereof and/or to give full effect to the terms of the Pre-Funded Warrant (as defined below), without regard to any limitations upon exercise of the Pre-Funded Warrant relating to any required approvals by Datavault's stockholders and (ii) the approval from the stockholders of Datavault with respect to an amendment to its certificate of incorporation to increase the number of shares of Common Stock authorized for issuance to up to 1.5 billion (or such greater amount as is necessary to issue the Pre-Funded Warrant Shares to Scilex)(such matters for which Stockholder Approval is required, the "Proposals"). Notwithstanding the foregoing, if Datavault is able to obtain the written consent of holders of a majority of the shares of its issued and outstanding Common Stock to obtain the Stockholder Approval (the "Stockholder Consent"), SHC may satisfy its obligations under the Datavault SPA to obtain the Stockholder Approval by obtaining such consent and submitting for filing with the SEC a Preliminary Information Statement on Schedule 14C no later than 15 days after the Initial Datavault Closing Date, followed by a Definitive Information Statement on Schedule 14C no later than the timeline for such filing prescribed by the Securities Exchange Act of 1934, as amended. Pursuant to the Datavault SPA, following Datavault's receipt of the Stockholder Approval, Datavault will issue SHC the Pre-Funded Warrant to purchase 263,914,094 shares of Common Stock (such shares, the "Pre-Funded Warrant Shares") in exchange for an aggregate of approximately $141.9 million. The aggregate purchase price for the Pre-Funded Warrant is based on the Per Share Purchase Price minus $0.0001 per share, multiplied by the number of shares subject to such warrant. The exercise price of the Pre-Funded Warrant will be $0.0001 per share. The Pre-Funded Warrant will be immediately exercisable upon issuance and will expire when exercised in full. The Pre-Funded Warrant contains certain anti-dilution provisions providing for the adjustment of the exercise price and shares issuable upon exercise in the event of a stock dividend of stock split of Datavault. Additionally, the Pre-Funded Warrant includes the right to acquire any rights to purchase Common Stock, warrants or other securities on the same terms as holders of Common Stock in such amount that the holder would have been entitled to if the Pre-Funded Warrant were exercised. The Pre-Funded Warrant also includes the right to receive any dividends declared by Datavault. The foregoing description of the Datavault SPA and the transactions contemplated thereby is qualified in its entirety by reference to the full text of the Datavault SPA, a copy of which is included as Exhibit 2 to this Schedule 13D and incorporated herein by reference.

The Reporting Person is deemed to be the beneficial owner of 15,000,000 shares of Common Stock held directly the Reporting Person, representing approximately 8.03% of the issued and outstanding Common Stock.
