Eureka Acquisition Corp, a Cayman Islands SPAC, reported unaudited results for the period ended June 30, 2026 while pursuing a Business Combination with Canadian autonomous shipping company Marine Thinking Inc.

Total assets were $33,636,929, largely investments in the Trust Account of $33,539,031, with only $22,727 of cash outside the trust.

Heavy redemptions continued: at the June 29, 2026 meeting, holders redeemed 2,655,132 Class A shares for $30,387,444, leaving 275,101 public Class A shares outstanding and creating a working capital deficit of $33,103,127.

A Nasdaq notice cited noncompliance with the Minimum Public Holders Rule, with an extension to October 3, 2026 to regain compliance.

Eureka Acquisition Corp filed a current report describing an amendment to its previously announced business combination agreement with Marine Thinking Inc. and its wholly owned Amalgamation Sub. The original agreement was signed on October 29, 2025 under the Canada Business Corporations Act framework.
On June 12, 2026, the parties executed Amendment No. 1, which changes section 5.19 of the agreement to revise the requirements for the post-closing directors of Eureka Acquisition Corp. All other terms of the business combination agreement remain unchanged and in full force. The complete amendment text is filed as Exhibit 2.1 to this report.
Eureka Acquisition Corp is calling a June 29, 2026 shareholder meeting to vote on extending the life of its SPAC, approving its auditor, and allowing a possible adjournment. The key Charter Amendment Proposal would move the deadline to complete a business combination to July 3, 2026, with up to twelve one‑month extensions to July 3, 2027, funded by a Monthly Extension Fee of the lesser of $15,000 or $0.03 per remaining public share paid into the trust.
The extension is intended to give more time to close Eureka’s planned business combination with Marine Thinking Inc., an autonomous ship and fleet solutions company, or another deal. Public shareholders may redeem their Class A shares in connection with the amendment for an estimated $11.42 per share based on the trust value as of the record date, compared with a $12.89 Nasdaq trading price. The trust held about $33.46 million at the record date, and there were 3,388,233 Class A and 1,437,500 Class B shares outstanding. Initial shareholders hold 1,665,500 shares, or 34.51%, and plan to vote for all proposals.
Eureka Acquisition Corp entered into a new financing arrangement to extend the time it has to complete its initial business combination. Marine Thinking Inc. deposited $150,000 into Eureka’s trust account, allowing the deadline to move from June 3, 2026 to July 3, 2026.
In return, Eureka issued a $150,000 unsecured, non‑interest‑bearing Extension Promissory Note to Marine Thinking, payable at the earlier of completing a business combination or the company’s expiry date. Marine Thinking may instead convert the note into private units at $10.00 per unit, each unit consisting of one Class A share and a right to receive one‑fifth of a Class A share after a business combination.
Eureka Acquisition Corp reported that Nasdaq has granted more time to fix its shareholder base issue. On June 5, 2026, the company received a letter from Nasdaq’s Listing Qualifications Department extending its deadline to comply with Nasdaq Listing Rule 5550(a)(3), the Minimum Public Holders Rule, until October 3, 2026.
The company had previously been notified that it failed to meet this requirement and submitted a compliance plan on April 20, 2026. This extension gives Eureka additional time to regain compliance and maintain its Nasdaq listing, but underscores ongoing pressure to increase the number of public holders.
Eureka Acquisition Corp, a Cayman Islands-based SPAC, reported unaudited results for the quarter ended March 31, 2026. Total assets were $33.0 million, almost all in a Trust Account of $32.8 million, with cash outside the trust of $151,622 and a shareholders’ deficit of about $2.1 million.

After significant prior redemptions, 2,930,233 Class A shares remain subject to redemption, and total ordinary shares outstanding were 4,825,733.
Eureka has a proposed Business Combination with Marine Thinking Inc. and has extended its transaction deadline through monthly extension fees of $150,000 each, funded by its sponsor and Marine Thinking via non‑interest-bearing promissory notes. Management discloses substantial doubt about the company’s ability to continue as a going concern if no Business Combination is completed by July 3, 2026.
