Michael Sinensky, a citizen of the United States, and Aeromaris MAS LLC, a Puerto Rico limited liability company

On October 1, 2026 (the "Closing Date"), pursuant to the Agreement and Plan of Merger (the "Merger Agreement"), dated March 8, 2026, as amended by Amendment No. 1, dated July 17, 2026, by and among the Issuer, Aureus Merger Sub Inc., a Delaware corporation and wholly owned subsidiary of the Issuer ("Merger Sub"), Autonomous Power Corporation, a Delaware corporation d/b/a Powerus ("Powerus"), and Andrew Fox (as Stockholder Representative), and the conditions set forth therein, Merger Sub merged with and into Powerus, with Powerus surviving the merger as a wholly owned subsidiary of the Issuer (the "Merger"). In connection with the Merger, the Issuer changed its name to "Powerus Corporation." In connection with the consummation of the Merger and other contemporaneous transactions (the "Closing"), all of the outstanding shares of common stock, par value $0.001 per share, of Powerus ("Powerus Common Stock") were converted into shares of Common Stock of the Issuer at an exchange ratio of 599.18229 shares of Common Stock for each share of Powerus Common Stock (the "Exchange Ratio") plus a pro rata portion of 55,000,000 additional shares of Common Stock (the "Earn Out Shares"). Fractional shares were rounded up to the nearest whole number. No cash consideration was paid in connection with the Merger. Additionally, each right to acquire Powerus Common Stock that was outstanding and unexercised, whether vested or unvested, immediately prior to the effective time of the Merger ceased to represent a right to acquire shares of Powerus Common Stock and was converted automatically into a right to acquire Common Stock, equitably adjusted by the Exchange Ratio. Aeromaris received 16,423,718 shares of Common Stock in exchange for its shares of Powerus Common Stock (100,000 of which were exchanged for Series A Preferred stock as noted in Item 5) and Mr. Sinensky received options to purchase up to 3,000,106 additional shares of Common Stock at a price of $0.75 per share. No funds were borrowed or otherwise obtained for the purpose of acquiring, holding, trading or voting the securities reported herein. The closing price of the Common Stock on October 1, 2026, was $3.20.
