Eureka Acquisition Corp is filing an amended Form S-4/A and preliminary proxy/prospectus to effect a business combination with Marine Thinking Inc. The proxy/prospectus registers up to 19,540,264 common shares of Marine Thinking to be issued at closing. The transactions include a legal continuance of Eureka from the Cayman Islands to Canada (the "SPAC Continuance"), an amalgamation of Marine Thinking with an SPAC subsidiary and conversion mechanics that fix the number of Pubco Class A Shares to be issued to Marine Thinking at 13,120,231 shares. The proxy outlines shareholder proposals for approval of governance changes (including an amendment to the net tangible asset threshold), the business combination agreement (as amended June 12, 2026), director appointments, a Pubco equity plan reserving 15% of fully diluted shares, Nasdaq listing actions, and related items. TheSponsor (Hercules Capital Management Corp) and insiders hold founder/private positions representing a meaningful pre-closing stake; pro forma tables show total Pubco Class A Shares outstanding at Closing of 19,540,264 under the no-redemption scenario. Redemption mechanics, multiple dilution/redemption scenarios, and pro forma net tangible book value analyses are disclosed in detail.
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 issued an unsecured promissory note for $150,000 to Marine Thinking Inc. to reimburse a monthly extension fee deposited into the Company’s trust account, thereby extending the deadline to complete its initial business combination by one month to July 3, 2026. The Extension Note is interest-free and matures upon either consummation of the business combination or the Company’s term expiry. Marine Thinking has a conversion right to receive Units at $10.00 per Unit by delivering conversion notice at least two business days prior to closing. The Note contains customary default events and conversion mechanics.
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 ("EURK") is asking shareholders to approve a charter amendment to extend its SPAC life by up to twelve one-month extensions, moving the termination date from July 3, 2026 to an Extended Termination Date of up to July 3, 2027, subject to monthly extension fees deposited to the Trust Account. The board says the extension is to allow completion of the proposed business combination with Marine Thinking Inc., which is being submitted separately for shareholder approval via a Form S-4. The proxy also seeks shareholder approval to engage Marcum Asia CPAs LLP as auditor and an adjournment authorization. Public shareholders may redeem their Class A shares for a pro rata portion of funds in the Trust Account if the charter amendment is approved; redemption procedures and deadlines are specified.

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.

The fee was paid by Marine Thinking Inc., and the Company issued an unsecured promissory note in the principal amount of $150,000 (the "Extension Note") dated April 4, 2026 to Marine Thinking. The Extension Note bears no interest and is payable upon the earlier of consummation of the business combination or the Company’s term expiry, and is convertible, at Marine Thinking’s option, into Units at $10.00 per Unit by providing notice at least two business days prior to closing.
