Columbus Acquisition Corp disclosed that it has used one of its available monthly extensions to push back the deadline to complete its initial business combination. Under its Charter, the company could extend the deadline month-by-month from January 22, 2026 up to January 22, 2027 by paying a fee.
On or about January 22, 2026, the company deposited $50,000, described as the Monthly Extension Fee, into its Trust Account for the benefit of public shareholders. This payment extends the time it has to complete its first business combination from January 22, 2026 to February 22, 2026, giving the company an additional month to pursue a suitable merger target.
Columbus Acquisition Corp held an extraordinary general meeting where shareholders approved changes to its charter and trust agreement. The new charter keeps the deadline to complete a business combination at January 22, 2026, but allows the company to elect up to twelve one-month extensions, potentially moving the outside date to January 22, 2027. The trust agreement was amended so the trustee must liquidate the trust account according to the revised charter timeline.
On the December 22, 2025 record date there were 7,944,290 ordinary shares outstanding. Shareholders approved both the charter and trust amendments by votes of 5,164,299 for and 1,188,717 against. In connection with the charter vote, 3,449,851 ordinary shares were submitted for redemption. After these redemptions, the company reports 4,494,439 ordinary shares outstanding, including 2,550,149 shares held by public shareholders.
