Item 8.01. Other Events

As previously disclosed on September 11, 2026, Columbus Acquisition Corp (the “Company”) convened its Extraordinary General Meeting of the Shareholders (the “Meeting”) on September 10, 2026, with a quorum present, for the purpose of approving the proposals set forth in the Company’s definitive proxy statement filed with the SEC on August 19, 2026 (the “Proxy Statement”), including the proposed business combination with WISeSat.Space Corp. The Chairman, exercising his authority as Chairman of the Meeting, adjourned the Meeting without submitting any proposals to a shareholder vote.

On September 23, 2026, the Company announced that the reconvened Meeting will be held on September 28, 2026, and the new extended redemption deadline (the “Extended Redemption Deadline”) will be September 24, 2026. Public shareholders seeking to exercise their redemption rights must complete the procedures described in the Proxy Statement by the Extended Redemption Deadline. As of September 23, 2026, there was approximately $10.79 per share in trust.

The record date for determining the Company shareholders entitled to receive notice of and to vote at the Meeting remains the close of business on August 17, 2026 (the “Record Date”). Shareholders as of the Record Date are eligible to vote, even if they have subsequently sold their shares.

If you have already voted, you do not need to vote again unless you would like to change or revoke your prior vote on any proposal.

If you have already submitted a proxy and do not wish to change your vote, you need not take any further action. If you have submitted a proxy and wish to change your vote, you may revoke your proxy at any time before it is exercised at the Meeting as provided in the Proxy Statement. Please note, however, that if your shares are held in street name by a broker or other nominee and you wish to revoke a proxy, you must contact the broker or nominee to revoke any prior voting instructions.
