On January 16, 2026, Columbus Acquisition Corp, a Cayman Islands exempted company (the “Company”) held an extraordinary general meeting of shareholders (the “Extraordinary General Meeting”), where the shareholders of the Company approved, among the other things, to amend the Investment Management Trust Agreement dated January 22, 2025 (the “Trust Agreement”), by and between the Company and Continental Stock Transfer & Trust Company, a New York limited purpose trust company (the “Trustee”) to provide that the Trustee must commence liquidation of the Company’s trust account (the “Trust Account”) by the prescribed timeline as provided in the Company’s Amended Charter (as defined below). Upon the shareholders’ approval, on January 16, 2026, the Company and the Trustee entered into the amendment to the Trust Agreement.
