[F1]As reported in the Form 8-K filed by the Issuer on 12/27/24, on 12/23/24, in connection with an acquisition transaction, the Issuer issued to the Reporting Person a 7% convertible note (the ?Note?). Subject to approval by the Committee on Foreign Investment in the United States ("CFIUS"), the Note was convertible by the Reporting Person into (i) 12,521,653 shares of common stock of the Issuer (the "First Conversion") and (ii) an additional 17,918,460 shares of common stock of the Issuer (the "Second Conversion"). The Second Conversion was subject to approval by the Issuer's stockholders. On 5/27/25, the Issuer received a CFIUS letter determining that the transaction was not a covered transaction under Section 721 of the Defense Production Act of 1950, as amended, and therefore was not subject to review by CFIUS. The First Conversion occurred on 9/5/25. The Issuer's stockholders approved the Second Conversion on 12/3/25, and the Second Conversion occurred on 12/10/25.
