Columbus Acquisition Corp. Form 8-K Filing

This Form 8-K filing reports on Columbus Acquisition Corp.'s extension of its business combination deadline. On May 21, 2026, the company deposited $50,000 into its trust account, extending the deadline to June 22, 2026. This deposit was funded by $25,000 from the company's working capital and $25,000 from WISeSat.Space Corp. (the "Target"). Concurrently, Columbus Acquisition Corp. issued an unsecured promissory note for $25,000 to the Target, representing the Target's contribution to the monthly extension fee. This note is due on the earliest of the Business Combination Agreement termination, the consummation of the business combination, or the company's winding up. The Target has the option to convert this note into private units or, under specific termination conditions, into shares of the post-closing public company.
