Each note is repayable upon a business combination or the company’s winding‑up, with additional conditions for the Target Extension Note tied to termination of the Business Combination Agreement. Both notes are optionally convertible into private units at $10.00 per unit, each unit comprising one ordinary share and a right to receive one‑seventh of an ordinary share, and the Target Extension Note can alternatively convert into post‑combination shares at $5.00 per share in certain scenarios.

Columbus Acquisition Corp reported that it has regained compliance with Nasdaq’s market value of listed securities requirement for the Nasdaq Global Market. Nasdaq had previously notified the company that its market value of listed securities was below the $50 million minimum for 30 consecutive business days. A later review found that, from May 13, 2026 to May 27, 2026, the company’s market value was at least $50 million for 10 straight business days, satisfying the rule. Nasdaq’s staff has confirmed the company is now back in compliance and has closed the matter.
Columbus Acquisition Corp received two Nasdaq deficiency notices related to its continued listing on the Nasdaq Global Market. Nasdaq determined the company no longer meets the minimum 400 shareholder requirement and that its market value of listed securities has been below the $50 million threshold for 30 consecutive business days.
The shareholder deficiency gives the company 45 calendar days, until July 6, 2026, to submit a compliance plan. Separately, it has 180 calendar days, until November 18, 2026, to restore its market value to at least $50 million for 10 straight business days. The notices do not immediately affect trading, but failure to regain compliance could result in delisting, though appeal and transfer to the Nasdaq Capital Market may be available.
