In return, Eureka issued Marine Thinking an unsecured, interest-free $150,000 Extension Promissory Note dated March 13, 2026. The note is payable upon either completion of the business combination or expiry of Eureka’s term and may be converted, at Marine Thinking’s option, into Eureka private units at $10.00 per unit, each unit consisting of one Class A ordinary share and one right to receive one-fifth of a Class A share.

The note bears no interest and is due upon the earlier of completing a business combination or the company’s expiry date, and includes standard event-of-default triggers that can accelerate repayment.
The sponsor may choose to convert the principal into private units at $10.00 per unit, with each unit consisting of one Class A ordinary share and a right to receive one-fifth of a Class A ordinary share after a business combination. These units, if issued, are restricted from transfer until the business combination and carry registration rights.

The company deposited $150,000 into its trust on October 31, 2025, extending the deadline to complete a business combination by one month, from November 3, 2025 to December 3, 2025. Under its charter, the period may be extended monthly, up to July 3, 2026, with each extension requiring a $150,000 deposit.

Any such units would be restricted from transfer until the business combination and carry registration rights. The issuance relies on Section 4(a)(2) of the Securities Act.
Eureka Acquisition Corp (EURK) entered into a Business Combination Agreement with Marine Thinking Inc. The SPAC will deregister from the Cayman Islands and domesticate to Canada, changing its name to Marine Thinking Holdings Inc., then complete an amalgamation in which Marine Thinking becomes a wholly owned subsidiary.
The exchange ratio (the “Amalgamation Multiple”) is based on Total Share Consideration of $130.0 million (plus any net Pre‑IPO investment, capped at $6.5 million) divided by $10.0 per SPAC Class A Share. At closing, each Unit splits into one Class A share and one Right, and each Right converts into one‑fifth of a Class A share; each Class B share converts into one Class A share. Governance post‑closing targets a seven‑member board with six Company designees (including four “independent” and one “financial expert”) and one Sponsor designee.
The parties agreed to support, voting, registration rights, and 365‑day lock‑up arrangements. The BCA includes mutual $2,000,000 termination fee triggers in specified cases. Prior agreements include an option over 583,333 SPAC shares for $1,750,000 (with a $1.00 exercise price for all option securities) and a finder fee payable in shares equal to 3% of Company Valuation divided by the Redemption Price.
