Eureka Acquisition Corp filings document the regulatory record of a Cayman Islands blank-check company with Nasdaq-listed units, Class A ordinary shares, and rights. Its current reports describe material definitive agreements, capital-structure terms, trust-account and extension mechanics, shareholder-vote matters, and written communications filed under Securities Act Rule 425.
The company’s filings also disclose SPAC governance matters, emerging growth company status, registered security classes, and listing-compliance events. These records center on the issuer’s blank-check purpose, redemption framework, rights structure, and public-company obligations before completion of an initial business combination.
Eureka Acquisition Corp, a Cayman Islands blank check company listed on Nasdaq, reports its first full fiscal year as a public SPAC and details a pending business combination.
In July 2024 it raised $57.5 million by selling 5,750,000 public units at $10.00 each and placing the proceeds in a trust account, alongside 228,000 private units. On June 30, 2025, holders redeemed 2,819,767 Class A shares, and approximately $29 million was released from the trust.
On October 29, 2025, EURK entered a business combination agreement with Marine Thinking Inc., an autonomous ship and fleet solutions company, and a Canadian subsidiary. The structure includes domestication to Canada as “Marine Thinking Holdings Inc.” followed by an amalgamation that will leave the combined operating company as a wholly owned subsidiary.
For the year ended September 30, 2025, EURK reported net income of $1,370,753, driven by $2,230,500 of interest on trust investments and $859,747 of general and administrative expenses. Cash outside the trust was $51,431 with a working capital deficiency of $625,273, and management cites substantial doubt about its ability to continue as a going concern if no business combination is completed by the current deadline.

After these sales, the fund continued to hold 395,924 Class A Ordinary Shares indirectly. The filing lists Wolverine Asset Management, Wolverine Holdings, Wolverine Trading Partners, and individuals Robert R. Bellick and Christopher L. Gust as reporting persons, each disclaiming beneficial ownership beyond any pecuniary interest.

Eureka Acquisition Corp (EURK) entered a financing arrangement to extend its SPAC timeline. 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.
The deposit was funded by the Sponsor, Hercules Capital Management Corp, in exchange for an unsecured, zero‑interest promissory note dated November 4, 2025, payable upon the earlier of the business combination or the company’s expiry. The Sponsor may convert amounts due into 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 ordinary share upon closing. 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.

Eureka Acquisition Corp filed an 8-K disclosing a material financing-related event: the company issued an Extension Promissory Note dated October 6, 2025 to Hercules Capital Management Corp. The filing lists the promissory note as Item 10.1, indicating a material agreement that modifies or extends the company's payment obligation to a lender. The disclosure is concise and does not include dollar amounts, interest terms, maturity details, or descriptions of operational impacts, so readers are informed that a material debt-related document exists but must consult the exhibit or lender communications for contractual specifics.
