Item 5.07. Submission of Matters to a Vote of Security Holders.
On September 30, 2026, Columbus Acquisition Corp,

(the “Meeting”), at which the shareholders voted on the proposals as set forth below, each of which is described in more
detail in the definitive proxy statement (the “Proxy Statement”) filed with the U.S. Securities and Exchange Commission (the
“SEC”) on August 19, 2026. Capitalized terms not otherwise defined herein shall have the same meaning ascribed thereto in

business combination (the “NTA Requirement”) as set out in Articles 37.2, 37.5, 37.6 and 37.8 of the CAC Articles, in order
to expand the methods that CAC may employ to not become subject to the “penny stock” rules of the SEC, immediately prior
to the Effective Time (as defined in the Plan of Merger) (the “NTA Proposal”).
Approval of the NTA Proposal requires the affirmative
vote of holders of at least two-thirds of the Company’s ordinary shares represented in person (including by virtual attendance)
