The foregoing persons are hereinafter collectively referred to as the "Reporting Persons". Any disclosures herein with respect to persons other than the Reporting Persons are made on information and belief after making inquiry to the appropriate party. The Reporting Persons have entered into a Joint Filing Agreement, a copy of which is filed as Exhibit 1 to the Statement on Schedule 13G filed with the the U.S Securities and Exchange Commission (the "SEC") on August 8, 2025 (the "Schedule 13G"), pursuant to which such Reporting Persons have agreed to file this Amendment No. 1 and all subsequent amendments to the Schedule 13G and this Amendment No. 1 jointly in accordance with the provisions of Rule 13d-1(k) of the Act. The filing of this Amendment No. 1 should not be construed in and of itself as an admission by any Reporting Person as to beneficial ownership of the shares of Common Stock reported herein. The principal business address of each of the Reporting Persons is 3053 Fillmore St, Suite 303, San Francisco, CA 94123. Hexstone is a limited liability company organized under the laws of the State of Nevada. Mr. O'Neil is a citizen of the United States. Y The purpose of this Amendment No. 1 is to amend and supplement the Schedule 13G in order to update the beneficial ownership information on the cover pages and in Item 4 in the Schedule 13G, including to indicate that each of the Reporting Persons has ceased to be the beneficial owner of more than five percent of the outstanding shares of Common Stock and to amend Item 5 of the Schedule 13G accordingly. This Amendment No. 1 constitutes an exit filing for each of the Reporting Persons. The information required by this item with respect to each Reporting Person is set forth in Rows 5 through 9 and 11 of the cover pages to this Amendment No. 1 and is incorporated herein by reference for each such Reporting Person. The share amounts and ownership percentages reported (i) are based on 4,240,134 shares of Common Stock outstanding as of November 21, 2025, as disclosed in the Prospectus, and (ii) do not give full effect to the exercise of the Warrants indirectly held by Hexstone, which are subject to a Blocker.
