Columbus Acquisition Corp extended the time to complete its initial business combination by one month, from July 22, 2026 to August 22, 2026, by depositing a $50,000 Monthly Extension Fee into its trust account on July 21, 2026. Under its charter, the deadline may be extended monthly up to January 22, 2027. The fee was funded equally by the Sponsor, Hercules Capital Management VII Corp, and the Target, WISeSat.Space Corp, at $25,000 each.
On July 30, 2026, the company issued two unsecured promissory notes of $25,000 each to the Target and the Sponsor (the Extension Notes), bearing no interest and payable upon consummation of a business combination, winding up, or specified termination events. Each payee may convert amounts outstanding into private units at $10.00 per unit, each unit consisting of one ordinary share and one right to receive one-seventh of an ordinary share. If Columbus terminates the Business Combination Agreement under a designated provision and later completes a different business combination, the Target may instead elect repayment or conversion into post-closing company shares at $5.00 per share. The notes and potential equity issuances rely on a private-offering exemption and the resulting securities carry transfer restrictions and registration rights.
Columbus Acquisition Corp extended the deadline to complete its initial business combination by one month to July 22, 2026 by depositing a $50,000 Monthly Extension Fee into its trust account. The sponsor and WISeSat.Space Corp. each funded $25,000, and on July 29, 2026 the company issued two unsecured, non‑interest‑bearing promissory notes in those amounts.
Each note is repayable upon a business combination or winding up, with the Target note also payable upon most terminations of the Business Combination Agreement. The payees may convert amounts into private units at $10.00 per unit, or, for the Target note after a specified termination, into post‑closing shares at $5.00 per share. The arrangements were made as unregistered offerings under Section 4(a)(2) of the Securities Act.
Columbus Acquisition Corp extended the deadline for completing its initial business combination by one month, from June 22, 2026 to July 22, 2026, by depositing a $50,000 Monthly Extension Fee into its Trust Account, as allowed by its charter for monthly extensions through January 22, 2027.
On July 29, 2026 the company issued two unsecured promissory notes: a $25,000 Target Extension Note to WISeSat.Space Corp. and a $25,000 Sponsor Extension Note to Hercules Capital Management VII Corp., each issued in connection with that party’s payment of 50% of the Monthly Extension Fee. The notes bear no interest. The Target note is payable upon the earlier of certain terminations of the Business Combination Agreement, completion of a business combination, or the company’s winding up; the Sponsor note is payable upon completion of a business combination or winding up.
Each note may be converted at the holder’s option into private units at $10.00 per unit, each unit consisting of one ordinary share and one right to receive one‑seventh of an ordinary share upon closing of a business combination. If the current transaction is validly terminated by the company under a specified provision and another business combination closes, the Target note holder may instead elect repayment or conversion into post‑closing shares at $5.00 per share. Any resulting Conversion Units or Conversion Shares are subject to lock‑up restrictions and carry registration rights.
Columbus Acquisition Corp amends an earlier report to clarify that the $50,000 Monthly Extension Fee used to extend its business combination deadline was funded equally by its sponsor and its merger target, WISeSat.Space Corp. Each party’s $25,000 contribution is evidenced by a separate unsecured promissory note.
Under the charter, paying the $50,000 fee on May 21, 2026 extended the deadline to complete an initial business combination from May 22, 2026 to June 22, 2026, with the period extendable in one‑month increments up to January 22, 2027. The Target Extension Note and Sponsor Extension Note bear no interest and are repayable upon completion of a business combination or winding up, with the target note also tied to certain termination outcomes.
Each note holder may elect to convert outstanding amounts into private units at $10.00 per unit, each unit consisting of one ordinary share and a right to receive one‑seventh of an ordinary share, and the target note also allows, in specified alternative‑transaction circumstances, conversion into post‑closing common or ordinary shares at $5.00 per share. The issuances rely on a Section 4(a)(2) exemption and the resulting securities carry transfer restrictions and registration rights.
Columbus Acquisition Corp filed an amendment updating how a Monthly Extension Fee for its SPAC business combination timeline was funded and documenting related promissory notes. Under its charter, the company can extend the deadline to complete an initial business combination from May 22, 2026 in one‑month increments up to January 22, 2027 by depositing a $50,000 Monthly Extension Fee into its trust account each month.
On May 21, 2026, $50,000 was deposited, extending the deadline to June 22, 2026. The amendment clarifies that $25,000 was paid by the sponsor, Hercules Capital Management VII Corp, and $25,000 by the proposed target, WISeSat.Space Corp. In connection with these payments, Columbus issued two unsecured, non‑interest‑bearing promissory notes: a $25,000 Target Extension Note dated May 21, 2026 and a $25,000 Sponsor Extension Note dated July 29, 2026.
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 Nasdaq granted an extension through November 18, 2026 for the company to regain compliance with Listing Rule 5450(a)(2), known as the Minimum Holders Rule for continued listing.

(Nasdaq: COLA) and related parties. The filing relates to a proposed business combination that would form a Nasdaq-listed operating company expected to trade as WSAT.

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.

The Company issued an unsecured promissory note for $25,000 to WISeSat.Space Corp. that is convertible into private units at $10.00 per unit or, in certain termination scenarios, into post-closing common/ordinary shares at $5.00 per share. The note bears no interest and is payable upon the earliest of termination, consummation of a business combination, or winding up.
