Added

On March 20, 2025, our board of directors accepted the resignation of Dr. M. Anthony Wong, the independent director, resigning from his position as a director of the Company.

Proposed Business Combination with Marine Thinking

Added

On October 29, 2025, EURK 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. (“Marine Thinking”), a 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 EURK (the “Amalgamation Sub,” together with EURK and Marine Thinking, the “Parties, “and each, a “Party”).

The BCA contemplates that the business combination among EURK, Marine Thinking and Amalgamation Sub will be completed through the following series of transactions, (i) prior to the time when the Amalgamation (as defined below) becomes effective (the “Amalgamation Effective Time”), EURK 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 EURK shall be changed from “Eureka Acquisition Corp” to “Marine Thinking Holdings Inc.” or such other name as the Parties may agree on; and (ii) 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”), Marine Thinking 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 Marine Thinking and Amalgamation Sub and in accordance with section 181 of the CBCA (the “Amalgamation”). Following the Amalgamation Effective Time, Amalco will become a direct wholly owned subsidiary of EURK.

June 2025 Shareholder Meeting

Added

On June 30, 2025, the Company held an extraordinary general meeting in lieu of an annual meeting of shareholders (the “Extraordinary General Meeting”).

Added

At the Extraordinary General Meeting, the shareholders of the Company approved the proposal (the “Charter Amendment Proposal”) to amend the Company’s Second Amended and Restated Memorandum and Articles of Association, which provided that the Company has until July 3, 2025 to complete a business combination, and may elect to extend the period to consummate a business combination up to two times, each by an additional three-month extension, for a total of up to six months to January 3, 2026, be deleted in their entirety and the substitution in their place of the Third Amended and Restated Memorandum and Articles of Association (the “Current Charter”) to provide that the Company has until July 3, 2025 to complete a business combination, and may elect to extend the period to consummate a business combination up to 12 times, each by an additional one-month extension (the “Monthly Extension”), for a total of up to 12 months to July 3, 2026. The Company agreed that it would not withdraw any interest from the Trust Account for payment of dissolution expenses.

Added

In connection with the Extraordinary General Meeting, 2,819,767 Class A Ordinary Shares were rendered for redemption, and approximately $29 million was released from the Trust Account to pay such redeeming shareholders.

Added

Trust Amendment

Added

In connection with the Extraordinary General Meeting, the Company entered into an amendment to the trust agreement dated July 2, 2024 (the “Trust Amendment”), by and between the Company and Continental Stock Transfer & Trust Company, a New York limited purpose trust company, as trustee (the “Trustee”).

Added

The Trust Amendment provides that, among other things, for each Monthly Extension, the amount of $150,000 (the “Monthly Extension Fee”) shall be deposited into the Trust Account, and, in the event that the Monthly Extension Fee is not being deposited into the trust account by the 3rd day of each month since July 3, 2025, the Company has a period of thirty (30) days (the “Cure Period”) to pay any applicable past due payment for the Monthly Extension Fee. If the Company fails to make any applicable past due payment during the Cure Period, then the Company shall immediately cease all operations, except for the purpose of winding up, and liquidate and dissolve with the same effect as if the Company failed to complete a business combination within the prescribed timeline.

Added

Extensions and Extension Notes

Added

Pursuant to the Current Charter, the Company currently has until January 3, 2026 to complete its business combination, which may be extended up to July 3, 2026 if fully extended by Monthly Extensions. As of the date hereof, an aggregate of $900,000 of the Monthly Extension Fee has been deposited into the Trust Account, among which $150,000 was paid by the Company from its working capital and $600,000 was paid by the Sponsor. In connection with the Sponsor’s payment of the Monthly Extension Fee, the Company issued five unsecured promissory notes in the aggregate principal amount of $750,000 (the “Extension Notes”) to the Sponsor. The Extension Notes bear no interest and are payable in full upon the earlier to occur of (i) the consummation of a business combination or (ii) the date of expiry of the term of the Company. The Sponsor, has the right, but not the obligation, to convert the Extension Notes, in whole or in part, respectively, into private units (the “Conversion Units”) of the Company, each consisting of one Class A Ordinary Share and one right to receive one-fifth (1/5) of one Class A Ordinary Share upon the consummation of a business combination. The number of Conversion Units to be received by the Sponsor in connection with such conversion shall be an amount determined by dividing (x) the sum of the outstanding principal amount payable to the Sponsor by (y) $10.00.

Added

Working Capital Loans

Added

On August 25, 2025, the Company issued an unsecured promissory note (the “Working Capital Note” and, together with the Extension Notes, the “Notes”) in the principal amount of up to $300,000 to the Sponsor. The proceeds of the Working Capital Note, which may be drawn down from time to time until the Company consummates its initial business combination, will be used as general working capital purposes (the “Working Capital Loans”).

Added

The Working Capital Note bears no interest and is payable in full upon the Maturity Date. The Sponsor, has the right, but not the obligation, to convert the Working Capital Note, in whole or in part, respectively, into Conversion Units upon the consummation of a business combination, as described in the prospectus of the Company (File No: 333-277780), by providing the Company with written notice of the intention to convert at least two business days prior to the closing of the business combination. The number of Conversion Units to be received by the Sponsor in connection with such conversion shall be an amount determined by dividing (x) the sum of the outstanding principal amount payable to the Sponsor by (y) $10.00.

Added

For the year ended September 30, 2025, we had a net income of $1,370,753, which consisted of interest income from the Trust Account of $2,230,500 offset by general and administrative expenses of $859,747. Cash used in operating activities was $668,921. Net income was offset by interest earned on investment held in the Trust Account. Changes in operating assets and liabilities provided $190,826 of cash for operating activities.

Removed

For the period from June 13, 2023 (inception) through September 30, 2023, we had a net loss of $5,325, all of which consisted of formation and operating costs. Cash used in operating activities was $4,269.

Reworded

As of September 30,2024, 30, 2025, we had $670,352$51,431 of cash held outside of the Trust Account, after payment of costs related to the IPO, and available for working capital purposes.

Removed

Over the next 12 months (assuming a business combination is not consummated prior thereto), we will be using the funds held outside of the Trust Account for identifying and evaluating prospective acquisition candidates, performing business due diligence on prospective target businesses, traveling to and from the offices, plants or similar locations of prospective target businesses, reviewing corporate documents and material agreements of prospective target businesses, selecting the target business to acquire and structuring, negotiating and consummating the business combination.

Added

As of September 30, 2025, we had cash of $51,431 and a working capital deficiency of $625,273. We have incurred and expect to continue to incur significant professional costs to remain as a publicly traded company and to incur significant transaction costs in pursuit of its financing and acquisition plans. The Company currently has no commitments to receive such financing and there is no assurance that the Company’s plans to raise capital will be successful. In addition, the Company has until January 3, 2026 (or up to July 3, 2026 if fully extended) to consummate the initial Business Combination. If the Company does not complete a Business Combination within the Combination Period, the Company will trigger an automatic winding up, dissolution and liquidation pursuant to the terms of the amended and restated memorandum and articles of association. In connection with the Company’s assessment of going concern considerations in accordance with Financial Accounting Standards Board’s Accounting Standards “Codification Subtopic 205-40, Presentation of Financial Statements - Going Concern”, management has determined that the mandatory liquidation, should a Business Combination not occur, and potential subsequent dissolution, along with the need to receive additional financing, raise substantial doubt about the Company’s ability to continue as a going concern until the earlier of the consummation of the Business Combination or the date the Company is required to liquidate. The audited consolidated financial statements do not include any adjustments that might result from the Company’s inability to continue as a going concern.

Removed

As of September 30, 2024, we had cash of $670,352 and a working capital deficiency of $684,474. We have incurred and expect to continue to incur significant professional costs to remain as a publicly traded company and to incur significant transaction costs in pursuit of the consummation of a business combination. In connection with our assessment of going concern considerations in accordance with Financial Accounting Standard Board’s Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” management has determined that these conditions raise substantial doubt about our ability to continue as a going concern. Our management’s plan in addressing this uncertainty is through the working capital loans from our Sponsor or its affiliates. In addition, if we are unable to complete a business combination within the Combination Period, our board of directors would proceed to commence a voluntary liquidation and thereby a formal dissolution of us. There is no assurance that our plans to consummate a business combination will be successful within the Combination Period. As a result, management has determined that such additional conditions also raise substantial doubt about our ability to continue as a going concern. Our financial statement does not include any adjustments that might result from the outcome of this uncertainty.

Reworded

In preparing these audited consolidated financial statements in conformity with US GAAP, management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the audited consolidated financial statements and the reported expenses during the reporting period.

Reworded

Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, actual results may differ from these estimates. We have not identified any critical accounting estimates.

Removed

In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2020-06”), to simplify accounting for certain financial instruments. ASU 2020-06 eliminates the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope exception guidance pertaining to equity classification of contracts in an entity’s own equity. The new standard also introduces additional disclosures for convertible debt and free-standing instruments that are indexed to and settled in an entity’s own equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for all convertible instruments. ASU 2020-06 is effective January 1, 2024 and should be applied on a full or modified retrospective basis, with early adoption permitted beginning on January 1, 2021. The Company adopted ASU 2020-06 as of the inception of the Company. Adoption of the ASU did not impact the Company’s financial position, results of operations or cash flows.

Reworded

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires the disclosure of additional segment information. ASU No. 2023-07 is effective for fiscal years beginning after December 15, 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company isadopted currentlyASU evaluating2023-07 in in its annual audited consolidated financial statements for the impactyear ofended adopting ASUSeptember 2023-07.30, 2025.

Removed

In December 2023, the FASB issued ASU 2023-09, Income taxes (Topic 740): Improvements to Income Tax Disclosure (“ASU 2023-09”), which enhances the transparency and usefulness of income tax disclosures. ASU 2023-09 will be effective for fiscal years beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The Company is currently evaluating the impact of adopting ASU 2023-09 on its financial statements.

As of MarchJune 31,30, 2026, we had cash of $151,622$22,727 available available for working capital needs. We intend to use substantially all of the net proceeds of the IPO, including the funds held in the Trust Account, to acquire a target business or businesses and to pay our expenses relating thereto. To the extent that our share capital is used in whole or in part as consideration to effect our initial business combination, the remaining proceeds held in the Trust Account as well as any other net proceeds not expended will be used as working capital to finance the operations of the target business. Such working capital funds could be used in a variety of ways including continuing or expanding the target business’ operations, for strategic acquisitions and for marketing, research and development of existing or new products. Such funds could also be used to repay any operating expenses or finders’ fees which we had incurred prior to the completion of our initial business combination if the funds available to us outside of the Trust Account were insufficient to cover such expenses.

As of MarchJune 31,30, 2026, the Company had $151,622$22,727 of cash and a working capital deficit of $2,066,415.$33,103,127 (including public shareholder redemption payable of $30,387,444). The Company has incurred and expects to continue to incur significant costs in pursuit of its financing and acquisition plans. The Company currently has no commitments in place to receive such financing and there is no assurance that the Company’s plans to raise capital will be successful. In addition, the Company has until August 3, 2026 (or up to July 3, 20262027, if extended) to consummate the initial business combination assuming full extensions. If the Company does not complete a business combination within the Combination Period, the Company will trigger an automatic winding up, dissolution and liquidation pursuant to the terms of the amended and restated memorandum and articles of association. Notwithstanding management’s belief that the Company would have sufficient funds to execute its business strategy, there is a possibility that business combination might not be completed within the 12-month period from the issuance date of these financial statements. In connection with the Company’s assessment of going concern considerations in accordance with Financial Accounting Standard Board’s Accounting Standards “Codification Subtopic 205-40, Presentation of Financial Statements - Going Concern”, management has determined that the mandatory liquidation, should a Business Combination not occur, and potential subsequent dissolution, along with the need to receive additional financing, raise substantial doubt about the Company’s ability to continue as a going concern until the earlier of the consummation of the Business Combination or the date the Company is required to liquidate. The auditedunaudited condensed consolidated financial statements do not include any adjustments that might result from the Company’s inability to continue as a going concern.

In December 2025, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. ASU 2025-11 clarifies the applicability of interim reporting guidance under ASC 270 and reorganizes interim disclosure requirements into a centralized framework.

The guidance is effective for interim periods within fiscal years beginning after December 15, 2027 for public business entities, with early adoption permitted. The Company is currently evaluating the impact that the adoption of ASU 2025-11 will have on its unaudited condensed financial statements and related disclosures.
