Rhea-AI Filing Summary

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.

Insights

EURK signs BCA; economics hinge on $10.0/share exchange math.

EURK agreed to merge with Marine Thinking Inc. via Canadian continuance and amalgamation. The Amalgamation Multiple is derived from $130.0 million (plus capped Pre‑IPO proceeds) divided by $10.0 per SPAC Class A share, defining share issuance at closing.

Mechanically, Units separate and Rights convert into one‑fifth of a share, while Class B becomes Class A. Post‑closing governance targets seven directors, primarily Company‑designated, with one Sponsor seat. Lock‑ups run 365 days, and mutual termination fees are $2,000,000.

Share dynamics also reflect a prior option for 583,333 shares at an aggregate $1,750,000 consideration (with $1.00 option exercise) and a finder fee of 3% of Company Valuation divided by the Redemption Price. Actual impact will depend on closing conditions and shareholder approvals.

Item 1.01 Entry Into a Material Definitive Agreement

 

Business Combination Agreement

 

On October 29, 2025, Eureka Acquisition Corp, a Cayman Islands exempted company (the “SPAC”), entered into a business combination agreement (as the same may be amended, supplemented or otherwise modified from time to time, the “BCA”), with Marine Thinking Inc., a company (the “Company”) incorporated under the Canada Business Corporations Act (“CBCA”) and 17358750 Canada Inc., a company incorporated under the CBCA and a wholly-owned subsidiary of the SPAC (the “Amalgamation Sub,” together with the SPAC and the Company, the “Parties, ” and each, a “Party”). The BCA and the transactions contemplated thereby were unanimously approved by the boards of directors of each of the SPAC and the Company.

 

The Business Combination

 

The BCA contemplates that the business combination among the SPAC, the Company and Amalgamation Sub will be completed through the following series of transactions:

 

 

 

prior to the time when the Amalgamation (as defined below) becomes effective (the “Amalgamation Effective Time”), the SPAC shall complete the deregistration as a Cayman Islands exempted company in accordance with section 206 of the Companies Act and, immediately upon such deregistration, the domestication to Canada under the CBCA (the “SPAC Continuance”). Upon the completion of the SPAC Continuance, the name of the SPAC shall be changed from “Eureka Acquisition Corp” to “Marine Thinking Holdings Inc.” or such other name as the Parties may agree on.
     
  following the SPAC Continuance, and in accordance with the applicable provisions of the BCA and in accordance with the CBCA, at the closing of the transactions contemplated by the BCA (the “Closing”), the Company and the Amalgamation Sub shall amalgamate and continue as one company, being the Amalco (“Amalco”), under the terms and conditions prescribed in the amalgamation agreement to be signed by the Company and Amalgamation Sub and in accordance with section 181 of the CBCA (the “Amalgamation”). Following the Amalgamation Effective Time, the Amalco will become a direct wholly owned subsidiary of the SPAC.

 

Conversion of Securities

 

At the Amalgamation Effective Time, by virtue of the Amalgamation and without any action on the part of any party or the holders of shares of the Company or the Amalgamation Sub:

In consideration of the foregoing issuance of the SPAC Class A Shares, Amalco shall issue to the SPAC one Amalco Share (as defined in the BCA) for each SPAC Class A Share so issued. Additionally, the SPAC shall receive one Amalco Share in exchange for each share of the Amalgamation Sub held by it and the shares of the Amalgamation Sub will be cancelled;

     
  (ii) Each Company Option issued and outstanding immediately prior to the Amalgamation Effective Time shall automatically be cancelled in exchange for a share option exercisable to receive SPAC Class A Shares (each, a “Rollover Option”) for each Company Option held, and shall no longer be outstanding and cease to exist by virtue of the Amalgamation. The Company shall assign, and the SPAC shall assume, the Company Option Agreements, and any restriction on any Company Option shall continue in full force and effect under the Rollover Option and the terms and other provisions of such Company Option shall otherwise remain unchanged, except for terms rendered inoperative by reason of the Transactions (as defined below) or for such other immaterial administrative or ministerial changes as the SPAC Board (or the compensation committee of the SPAC Board) may determine in good faith are necessary to effectuate the administration of the Rollover Options. The number of the SPAC Class A Shares issuable upon exercise of each Rollover Option shall be determined by multiplying the number of Company Shares (as defined below) that were subject to such Company Option immediately prior to the consummation of the Amalgamation by the Amalgamation Multiple, and rounding the resulting number down to the nearest whole number of the SPAC Class A Shares.

  (iii) Each share of the Amalgamation Sub shall automatically be cancelled in exchange for the right to receive one fully paid and non-assessable Amalco Share, following which shares of the Amalgamation Sub shall no longer be outstanding and cease to exist by virtue of the Amalgamation.

 

At the Amalgamation Effective Time, without any action on the part of any Party or the holders of shares of the SPAC:

 

(i) Each SPAC Unit (as defined below) issued and outstanding immediately prior to the Closing shall (to the extent not already separated) be automatically severed and the holder thereof shall be deemed to hold one SPAC Class A Share and one SPAC Right (as defined below) in accordance with the terms of the applicable SPAC Unit;
     
  (ii) Each SPAC Right issued and outstanding immediately prior to the Closing shall be automatically converted into one-fifth of a SPAC Class A Share; and

The options are exercisable for the period commencing on the expiration or early release of applicable transfer restrictions on the Option Securities (as provided in the letter agreement dated July 2, 2024 entered into by and among the SPAC, the SPAC Sponsor and certain other parties in connection with the SPAC’s initial public offering) and ending on July 5, 2026. On September 23, 2025, the Company entered into an option assignment agreement (the “Option Assignment Agreement”) and assigned its rights, interests and obligations in whole under the Option Purchase Agreement to a company that is owned by the current shareholders of the Company in substantially similar proportions as their respective shareholdings in the Company.

 

The foregoing description of the Option Purchase Agreement and the Option Assignment Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Option Purchase Agreement and the Option Assignment Agreement, which are attached hereto as Exhibit 10.5 and Exhibit 10.6, respectively.

The SPAC urges investors, shareholders and other interested persons to read, when available, the preliminary proxy statement/prospectus as well as other documents filed with the SEC because these documents will contain important information about the SPAC, the Company, Amalco and the proposed transactions. After the registration statement is declared effective, the definitive proxy statement/prospectus to be included in the registration statement will be mailed to shareholders of the SPAC as of a record date to be established for voting on the proposed transactions. Shareholders will also be able to obtain a copy of the proxy statement/prospectus, without charge by directing a request to eric.zhang@herculescapital.group. The preliminary and definitive proxy statement/prospectus to be included in the registration statement, once available, can also be obtained, without charge, at the SEC’s website (www.sec.gov).

 

No Offer or Solicitation

 

This Current Report on Form 8-K is not a proxy statement or solicitation of a proxy, consent or authorization with respect to any securities or in respect of the proposed transactions described herein, and does not constitute an offer to sell or a solicitation of an offer to buy any securities of the SPAC or the Company,  or a solicitation of any vote or approval, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offer of securities shall be made except by means of a prospectus meeting the requirements of the Securities Act of 1933, as amended.

 

Participants in the Solicitation

Information regarding the persons who may, under the rules of the SEC, be deemed participants in the solicitation of the stockholders in connection with the proposed transactions will be set forth in the proxy statement/prospectus when it is filed with the SEC.

Statements that are not historical facts are forward-looking statements. Forward-looking statements are based on current beliefs and assumptions that are subject to risks and uncertainties and are not guarantees of future performance. Actual results could differ materially from those contained in any forward-looking statement as a result of various factors, including, without limitation: (i) the risk that the conditions to the closing of the proposed transaction are not satisfied, including the failure to timely or at all obtain shareholder approval for the proposed transaction or the failure to timely or at all obtain any required regulatory approval; (ii) uncertainties as to the timing of the consummation of the proposed transaction and the ability of each of involving the SPAC and the Company to consummate the proposed transaction; (iii) the possibility that other anticipated benefits of the proposed transaction will not be realized, and the anticipated tax treatment of the proposed transaction; (iv) the occurrence of any event that could give rise to termination of the proposed transaction; (v) the risk that shareholder litigation in connection with the proposed transaction or other settlements or investigations may affect the timing or occurrence of the proposed transaction or result in significant costs of defense, indemnification and liability; (vi) changes in general economic and/or industry specific conditions; (vii) possible disruptions from the proposed transaction that could harm the Company business; (viii) the ability of the Company to retain, attract and hire key personnel; (ix) potential adverse reactions or changes to relationships with customers, employees, suppliers or other parties resulting from the announcement or completion of the proposed transaction; (x) potential business uncertainty, including changes to existing business relationships, during the pendency of the proposed transaction that could affect the Company’s financial performance; (xi) legislative, regulatory and economic developments; (xii) unpredictability and severity of catastrophic events, including, but not limited to, acts of terrorism, outbreak of war or hostilities and any epidemic, pandemic or disease outbreak, as well as management’s response to any of the aforementioned factors; and (xiii) other risk factors as detailed from time to time in the SPAC’s reports filed with the SEC, including the SPAC’s annual report on Form 10-K, periodic quarterly reports on Form 10-Q, periodic current reports on Form 8-K and other documents filed with the SEC. The foregoing list of important factors is not exclusive. Neither the SPAC nor the Company can give any assurance that the conditions to the proposed transaction will be satisfied. Except as required by applicable law, neither the SPAC nor the Company undertakes any obligation to revise or update any forward-looking statement, or to make any other forward-looking statements, whether as a result of new information, future events or otherwise.
