Columbus Acquisition Corp extended the deadline to complete its initial business combination from May 22, 2026, to June 22, 2026. The extension was secured by depositing $50,000 into the company's trust account. Funding for the extension was split equally: $25,000 from the company's working capital and $25,000 from the target company, WISeSat.Space Corp. The company issued a $25,000 unsecured promissory note to WISeSat.Space Corp to cover the target's portion of the extension fee.
