NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2026

Note 1 — Organization, Business Operation and Going Concern Consideration

Eureka Acquisition Corp (the “Company” or “Eureka”) is a blank check company incorporated in the Cayman Islands on June 13, 2023. The Company was formed for the purpose of entering into a merger, share exchange, asset acquisition, share purchase, recapitalization, reorganization or similar business combination with one or more businesses or entities, which is referred to as a “target business” (the “Business Combination”). The Company has selected September 30 as its fiscal year end.

As of March 31, 2026, the Company had not commenced any operations. For the period from June 13, 2023 (inception) through March 31, 2026, the Company’s efforts have been limited to organizational activities as well as activities related to the initial public offering (the “IPO”) described below, and subsequent to the IPO, identifying a target company for a Business Combination and preparing the Transactions (as defined below). The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company will generate non-operating income in the form of dividend and/or interest income from the proceeds derived from the IPO and sale of Private Units (as defined below).

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the IPO and the sale of the Private Units, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully.

The Company’s founder and sponsor is Hercules Capital Management Corp, a British Virgin Islands company (the “Sponsor”). The Company’s ability to commence operations is contingent upon obtaining adequate financial resources through the IPO (see Note 3) and a private placement to the initial shareholder (see Note 4).

The registration statement on Form S-1 in connection with the for the Company’s IPO was declared effective on July 1, 2024. On July 3, 2024, the Company consummated its IPO of 5,000,000 units (“Units”). Each Unit consists of one Class A ordinary share, $0.0001 par value per share, and one right to receive one-fifth of one Class A ordinary share upon the completion of the initial Business Combination. The Units were sold at an offering price of $10.00 per Unit, generating total gross proceeds of $50,000,000. On July 3, 2024, the underwriter notified the Company of its exercise of the over-allotment option in full to purchase additional 750,000 Units (the “Option Units”) of the Company (the “Over-Allotment Option”). As a result, on July 8, 2024, 750,000 Units were sold to the underwriter at an offering price of $10.00 per Option Unit (the “Option Units” and together with the Units, collectively, the “Public Units”), generating gross proceeds of $7,500,000.

Simultaneously with the consummation of the IPO and the sale of the Units, the Company consummated the private placement of 216,750 units (the “Initial Private Placement Units”) to the Sponsor, at a price of $10.00 per Initial Private Placement Unit, generating total proceeds of $2,167,500, which is described in Note 4. Simultaneously with the issuance and sale of the Option Units, the Company completed a private placement sale of additional 11,250 units (the “Additional Private Units” and together with the Initial Private Placement Units, collectively, the “Private Units”) to the Sponsor at a purchase price of $10.00 per Additional Private Unit, generating gross proceeds of $112,500.

Transaction costs amounted to $1,600,914 consisting of $862,500 of underwriting commissions which was paid in cash at the closing date of the IPO and Over-allotment Option, $301,300 of the Representative Shares (discussed in the below), $150,000 of underwriter expenses, and $287,114 of other offering costs, all of which were recognized by the Company during the three months ended September 30, 2025. At the closing date of the IPO and Over-allotment Option, cash of $827,216 was held outside of the Trust Account (as defined below) and is available for the payment of accrued offering costs and for working capital purposes.

In conjunction with the IPO, the Company issued to the underwriter 200,000 Class A ordinary shares for no consideration (the “Representative Shares”) with an estimated fair value of $262,000. In connection with the issuance and sales of the Option Units, the Company issued an additional 30,000 Representative Shares with an estimated fair value of $39,300 to the underwriter. The fair value of the Representative Shares accounted for as compensation under Accounting Standards Codification (“ASC”) 718, “Compensation – Stock Compensation” (“ASC 718”) is included in the offering costs.

The Company’s initial Business Combination must occur with one or more target businesses that together have an aggregate fair market value of at least 80% of the balance in the Trust Account (as defined below), (less any taxes payable on interest earned) at the time of execution of the definitive agreement in connection with its initial Business Combination. However, the Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for the post-transaction company not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). The Company does not believe that its anticipated principal activities will subject the Company to the Investment Company Act. There is no assurance that the Company will be able to complete a Business Combination successfully.

Upon the closing of the IPO, management has agreed that at least $10.00 per Public Unit sold in the IPO would be held in a U.S.-based trust account (“Trust Account”). The funds held in the Trust Account will be invested only in U.S. government treasury bills with a maturity of 185 days or less, or in money market funds meeting the applicable conditions of Rule 2a-7 promulgated under the Investment Company Act which invest solely in direct U.S. government treasury securities or in an interest bearing or non-interest bearing demand deposit account. Except with respect to dividend and/or interest earned on the funds held in the Trust Account that may be released to the Company to pay the Company’s tax obligation, if any, the proceeds from the IPO and the sale of the Private Units that are deposited and held in the Trust Account will not be released from the Trust Account until the earliest to occur of (i) the completion of the Company’s initial Business Combination, (ii) the redemption of any public shares properly tendered in connection with a shareholder vote to amend the Company’s amended and restated memorandum and articles of association to (A) modify the substance or timing of obligation to redeem 100% of our public shares if the Company does not complete the Company’s initial Business Combination within the prescribed period as provided in the Company’s amended and restated memorandum and articles of association (the “Combination Period”) or (B) with respect to any other provision relating to shareholders’ rights or pre-Business Combination activity and (iii) the redemption of all of the Company’s public shares if the Company is unable to complete their initial Business Combination within Combination Period, subject to applicable law. In no other circumstances will a public shareholder have any right or interest of any kind to or in the Trust Account.

The Company will provide the holders of public shares with the opportunity to redeem all or a portion of their public shares upon the completion of the Business Combination either (i) in connection with a shareholder meeting called to approve the Business Combination or (ii) by means of a tender offer.

The Company has determined not to consummate any Business Combination unless the Company has net tangible assets of at least $5,000,001 upon such consummation in order to avoid being subject to Rule 419 promulgated under the Securities Act. However, if the Company seeks to consummate an initial Business Combination with a target business that imposes any type of working capital closing condition or requires us to have a minimum amount of funds available from the Trust Account upon consummation of such initial Business Combination, its net tangible asset threshold may limit the Company’s ability to consummate such initial Business Combination (as the Company may be required to have a lesser number of shares redeemed) and may force the Company to seek third party financing which may not be available on terms acceptable to the Company or at all. As a result, the Company may not be able to consummate such an initial Business Combination and the Company may not be able to locate another suitable target within the applicable time period, if at all.

The Company will have until up to July 3, 2026 (if the Company fully extends the Combination Period) to complete its initial Business Combination. If the Company is unable to complete its initial Business Combination by July 3, 2026, the Company will: (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (less up to $50,000 of interest to pay dissolution expenses (which interest shall be net of taxes payable)) divided by the number of then outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of its remaining shareholders and its Board of Directors, liquidate and dissolve, subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to its public rights or private placement rights, which will expire worthless if the Company fails to complete its initial Business Combination by July 3, 2026 if fully extended.

On March 20, 2025, the Company’s board of directors accepted the resignation of Dr. M. Anthony Wong, the independent director, resigning from his position as a director of the Company. Concurrently, the Company, by ordinary resolutions of its directors, appointed Mr. Cameron Richard Johnson as the independent director of the Company to fill the vacancy, effective immediately. Mr. Cameron Richard Johnson was also appointed as the chairperson of the Audit Committee and a member of the Compensation Committee. The Company entered into an Indemnity Agreement with Mr. Johnson on March 20, 2025, accordingly.

In connection with the appointment of Mr. Johnson as the director of the Company, the Sponsor issued a share purchase option dated March 20, 2025 (the “Share Purchase Option”) to Mr. Johnson, entitling Mr. Johnson to acquire 10,000 ordinary shares of the Company held by the Sponsor (the “Founder Shares”) upon the exercise of the Share Purchase Option once the existing lock-up term on such Founder Shares expires pursuant to the terms and arrangements thereunder.

On September 29, 2025, 17358750 Canada Inc., a company incorporated under the Canada Business Corporations Act and a wholly owned subsidiary of Eureka, was formed in connection with a contemplated business combination. Amalgamation Sub (as defined below) has no principal operations or revenue producing activities.

Proposed Business Combination with Marine Thinking

On October 29, 2025, the Company 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.

The BCA contemplates that the business combination among Eureka, 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”), Eureka 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 Eureka 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 Eureka.

The Continuance, the Amalgamation, and the other transactions contemplated by the BCA are hereinafter referred to as the “Transactions.”

Support Agreement

Concurrently with the execution of the BCA, the Sponsor, Eureka and Marine Thinking have entered into a support agreement (the “Support Agreement”) pursuant to which, among other things, the Sponsor agreed to (i) vote, or cause to be voted or consented at any meeting of the shareholders of Eureka, or in any action by written consent of the shareholders, all of its SPAC Shares (as defined in the BCA) which Eureka the Sponsor owns of record or has the power to vote as of the record date for such meeting (the “Sponsor Shares”), (a) in favor of the approval and adoption of the BCA and the Transactions contemplated thereby, and any other matter reasonably necessary to the consummation of the Business Combination, and (b) against the proposals in connection with other alternative business combinations other than the Business Combination with Marine Thinking; and (ii) not to transfer any Sponsor Shares until the Expiration Time (as defined in the Support Agreement).

Voting Agreement

Concurrent with the execution and delivery of the BCA, Marine Thinking, Eureka, the Amalgamation Sub and certain shareholders of Marine Thinking (the “Requisite Shareholders”), have entered into a voting agreement (the “Voting Agreement”), pursuant to which the Requisite Shareholders agreed to, among other things, (i) vote, or cause to be voted or consented at a meeting of the holders of the common shares in the capital of Marine Thinking (“Target Shareholders”), or in any action by written consent of the shareholders, all common shares of Marine Thinking which the Requisite Shareholders own of record or have the power to vote (including any successor shares of Company of which ownership of record or the power to vote is hereafter acquired by the Requisite Shareholders prior to the termination of the Company Voting Support Agreement) (the “Subject Shares”), (a) in favor of the approval and adoption of the BCA and the Transactions contemplated thereby, and any other matter reasonably necessary to the consummation of the Business Combination, and (b) against the proposals in connection with other alternative business combinations other than the Business Combination with Eureka; and (ii) not to transfer any Subject Shares until the Expiration Time (as defined in the Voting Agreement).

Registration Rights Agreement

The BCA contemplates that, at the Closing, Eureka, the Sponsor, each of the Target Shareholders and certain other parties named therein will enter into an amended and restated registration rights agreement (the “Registration Rights Agreement”), pursuant to which Eureka will agree to register for resale, pursuant to applicable securities laws and regulations, with respect to the registrable securities held by the Holders (as defined in the Registration Rights Agreement).

Lock-Up Agreements

The BCA contemplates that at the Closing, each of the Sponsor and certain of the Target Shareholders will enter into a lock-up agreement (collectively, the “Lock-up Agreements”), pursuant to which (i) the Sponsor agrees on certain restrictions on transfer of SPAC Class B Shares (as defined in the BCA) held by the Sponsor immediately prior to the Closing; and (ii) certain of the Target Shareholders agree on certain restrictions on transfer of SPAC Shares held by them immediately after the Closing, including any shares issuable upon the exercise of any rights, options, warrants or other securities to purchase any SPAC Shares held by them immediately after the Closing, or any rights, options, warrants or other securities convertible into or exercisable or exchangeable for any SPAC Shares held by them immediately after the Closing. The lock-up period commences on the Amalgamation Effective Time and continues until the earlier of (i) three-hundred and sixty-five (365) days after the Closing, or (ii) the date on which Eureka completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of Eureka’s shareholders having the right to exchange their SPAC Shares or other equity securities of Eureka for cash, securities or other property.

Option Purchase Agreement

On July 6, 2025, the Sponsor and Marine Thinking entered into an option purchase agreement (as amended on September 2, 2025, the “Option Purchase Agreement”), pursuant to which the Sponsor agreed to sell to Marine Thinking, and Marine Thinking agreed to purchase from the Sponsor, an option to purchase 583,333 SPAC Shares held by the Sponsor (the “Option Securities”) for an aggregate purchase price of $1,750,000. The aggregate exercise price of the option itself is $1.00 for all of the Option Securities. 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 Eureka, the Sponsor and certain other parties in connection with the IPO) and ending on July 5, 2026. On September 23, 2025, Marine Thinking 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 Marine Thinking in substantially similar proportions as their respective shareholdings in Marine Thinking.

Finder’s Agreement

On April 1, 2025, Eureka entered into a finder’s agreement (the “Finder’s Agreement”) with Alpha Innovators Limited, a British Virgin Islands exempted company (the “Finder”), pursuant to which the Finder agreed to introduce potential targets to Eureka. If Eureka consummates a business combination with one or more targets introduced by the Finder during the term of the Finder’s Agreement and a period of twelve (12) months following the termination of the Finder’s Agreement, then Eureka shall issue to the Finder or its designated affiliates, upon the completion of each business combination(s) and as complete and full compensation for the Finder under Finder’s Agreement, a number of SPAC Class A Shares equal to the quotient obtained by dividing 3% of the Company Valuation (as defined in the BCA) by the Redemption Price (as defined in the BCA).

June 2025 Shareholder Meeting

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

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.

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

Trust Amendment

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”).

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.

Extensions and Extension Notes

Pursuant to the Current Charter, the Company currently has until June 3, 2026 (or up to July 3, 2026 if fully extended) to complete its business combination. If the Company is unable to complete its initial Business Combination by the Combination Period, the Company will: (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable) divided by the number of then outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of its remaining shareholders and its Board of Directors, liquidate and dissolve, subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to its public rights or private placement rights, which will expire worthless if the Company fails to complete its initial Business Combination by the Combination Period.

As of the date hereof, an aggregate of $1,650,000 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, $1,050,000 was paid by the Sponsor and $450,000 was paid by Marine Thinking, respectively. In connection with the payment of the Monthly Extension Fee, the Company issued seven unsecured promissory notes in the aggregate principal amount of $1,050,000 (the “Sponsor Extension Notes”) to the Sponsor, and three unsecured promissory notes in the aggregate principal amount of $450,000 to Marine Thinking (the “Target Extension Notes” and, together with the Sponsor Extension Notes”, collectively, the “Extension Notes”), respectively. 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 payees of the Extension Notes have the right, but not the obligation, to convert the Extension Notes, in whole or in part, respectively, into private units (the “Extension 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 Extension Units to be received by the payees in connection with such conversion shall be an amount determined by dividing (x) the sum of the outstanding principal amount payable to such payee by (y) $10.00.

Going Concern Consideration

As of March 31, 2026, the Company had $151,622 of cash and a working capital deficit of $2,066,415. 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 July 3, 2026 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. 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 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 unaudited condensed consolidated financial statements do not include any adjustments that might result from the Company’s inability to continue as a going concern. The unaudited condensed consolidated financial statements do not include any adjustments that might result from the Company’s inability to continue as a going concern.

Risks and Uncertainties

Various social and political circumstances in the U.S. and around the world (including rising trade tensions between the U.S. and China, and other uncertainties regarding actual and potential shifts in the U.S. and foreign, trade, economic and other policies with other countries), may contribute to increased market volatility and economic uncertainties or deterioration in the U.S. and worldwide. As a result of these circumstances and the ongoing global conflicts and/or other future global conflicts, the Company’s ability to consummate a Business Combination, or the operations of a target business with which the Company ultimately consummates a Business Combination, may be materially and adversely affected. In addition, the Company’s ability to consummate a transaction may be dependent on the ability to raise equity and debt financing which may be impacted by these events, including as a result of increased market volatility, or decreased market liquidity in third-party financing being unavailable on terms acceptable to the Company or at all. The impact of this action and related sanctions on the world economy and the specific impact on the Company’s financial position, results of operations and/or ability to consummate a Business Combination are not yet determinable. The unaudited condensed consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties.

Note 2 — Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC. In the opinion of management, all adjustments consisting of normal recurring adjustments considered necessary for a fair presentation of the financial statements, have been included. Interim results three and six months ended March 31, 2026 are not necessarily indicative of results that may be expected through September 30, 2026 or for any future periods. These financial statements should be read in conjunction with the Company’s 2025 Annual Report on Form 10-K as filed with the SEC on December 15, 2025.

Principles of consolidation

The unaudited consolidated financial statements include the financial statements of the Company and its wholly owned subsidiaries. All transactions and balances between the Company and its subsidiaries have been eliminated upon consolidation.

Emerging Growth Company Status

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended, (the “Securities Act”), as modified by the Jumpstart Our Business Startups Act of 2012, (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. 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 financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. As of March 31, 2026 and September 30, 2025, the Company had $151,622 and $51,431 in cash, respectively, and none in cash equivalents for both periods.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the United States Federal Depository Insurance Coverage of $250,000. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s financial condition. As of March 31, 2026 and September 30, 2025, the Company has not experienced losses on these accounts.

Investments Held in Trust Account

The Company’s portfolio of investments held in the Trust Account is comprised of investments in U.S. government treasury bills with a maturity of 185 days or less. These securities are presented on the balance sheet at fair value at the end of each reporting period. Earnings on investments held in the Trust Account are included in interest earned on investments held in the Trust Account in the accompanying statements of operations. The estimated fair value of investments held in the Trust Account is determined using available market information. Upon maturity of these U.S. government securities on December 12, 2024, the Company invested the proceeds into an interest-bearing demand deposit account, which comprised the entire balance of the Trust Account as of March 31, 2026 and earned $272,856 and $572,209 of interest income during the three and six months ended March 31, 2026, respectively. The Company earned $594,603 and $1,288,659 of interest income during the three and six months ended March 31, 2025, respectively.

Offering Costs Associated with the IPO

Offering costs were $1,600,914 consisting principally of underwriting, legal and other expenses incurred through the balance sheet date that were related to the IPO and were charged to shareholders’ equity upon the completion of the IPO. The Company complies with the requirements of the ASC 340-10-S99-1 and SEC Staff Accounting Bulletin (“SAB”) Topic 5A - “Expenses of Offering”. The Company allocates offering costs among public shares, public rights and Private Units based on the relative fair values of public shares, public rights and Private Units. Accordingly, $1,554,984 was allocated to public shares and charged to temporary equity, and $45,930 was allocated to public rights and Private Units and charged to shareholders’ equity.

Share Rights

The Company accounts for the public rights and private placement rights issued in connection with the IPO and the Private Placement in accordance with the guidance contained in FASB ASC Topic 815, “Derivatives and Hedging”. Accordingly, the Company evaluated and classified the rights under equity treatment at their assigned values.

Class A ordinary shares subject to possible redemption

The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in ASC Topic 480, “Distinguishing Liabilities from Equity” (ASC 480). Ordinary shares subject to mandatory redemption (if any) will be classified as a liability instrument and will be measured at fair value. Conditionally redeemable ordinary shares (including ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) will be classified as temporary equity. At all other times, ordinary shares will be classified as shareholders’ equity. In accordance with ASC 480-10-S99, the Company classifies the Class A ordinary shares subject to redemption outside of permanent equity as the redemption provisions are not solely within the control of the Company. Given that the 5,750,000 Class A ordinary shares sold as part of the Units in the IPO were issued with other freestanding instruments (i.e., rights), the initial carrying value of Class A ordinary shares classified as temporary equity has been allocated to the proceeds determined in accordance with ASC 470-20. If it is probable that the equity instrument will become redeemable, the Company has the option to either (i) accrete changes in the redemption value over the period from the date of issuance (or from the date that it becomes probable that the instrument will become redeemable, if later) to the earliest redemption date of the instrument or (ii) recognize changes in the redemption value immediately as they occur and adjust the carrying amount of the instrument to equal the redemption value at the end of each reporting period. The Company has elected to recognize the changes in redemption value as a charge against additional paid-in capital or, in the absence of additional paid-in capital, as a charge against retained earnings over an expected 12-month period, which is the initial period that the Company has to complete a Business Combination. The Company uses the effective interest method to calculate the periodic accretion under which the accreted redemption value equals the redemption amount on the earliest redemption date. Additionally, interest earned in the Trust Account is recognized as an increase to the redemption value immediately as it is earned. For the three and six months ended March 31, 2026, the Company recorded $272,856 and $572,209 interest income as a remeasurement of carrying value to redemption value. For the three and six months ended March 31, 2025, the Company recorded $594,603 and $1,288,659 interest income as a remeasurement of carrying value to redemption value.

Accordingly, as of March 31, 2026 and September 30, 2025, Class A ordinary shares subject to possible redemption are presented at redemption value as temporary equity, outside of permanent shareholders’ equity on the Company’s balance sheet in the following table:

	Shares			Amount

Net Income (Loss) Per Ordinary Share

The Company complies with accounting and disclosure requirements of FASB ASC 260, Earnings Per Share. The unaudited condensed consolidated statements of operations include a presentation of income (loss) per redeemable share and income (loss) per non-redeemable share following the two-class method of income per share. In order to determine the net income (loss) attributable to both the redeemable shares and non-redeemable shares, the Company first considered the undistributed income (loss) allocable to both the redeemable shares and non-redeemable shares and the undistributed income (loss) is calculated using the total net loss less any dividends paid. The Company then allocated the undistributed income (loss) ratably based on the weighted average number of shares outstanding between the redeemable and non-redeemable shares. Any remeasurement of the accretion to redemption value of the common shares subject to possible redemption was considered to be dividends paid to the public shareholders.

The calculation of diluted income per ordinary share does not consider the effect of the rights issued in connection with the IPO and the Private Units since the exercise of the units is contingent upon the occurrence of future events. As of March 31, 2026 and September 30, 2025, the Company did not have any dilutive securities or other contracts that could, potentially, be exercised or converted into ordinary shares that then share in the earnings of the Company. As a result, diluted net income (loss) per ordinary share is the same as basic net income (loss) per ordinary share for the periods presented.

The net income (loss) per share presented in the unaudited condensed statements of operations is based on the following:

	Three Months Ended March 31,					Six Months Ended March 31,
	2026		2025			2026		2025

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC 820, “Fair Value Measurement” (“ASC 820”), approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature.

The Company applies ASC 820, which establishes a framework for measuring fair value and clarifies the definition of fair value within that framework. ASC 820 defines fair value as an exit price, which is the price that would be received for an asset or paid to transfer a liability in the Company’s principal or most advantageous market in an orderly transaction between market participants on the measurement date. The fair value hierarchy established in ASC 820 generally requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs reflect the assumptions that market participants would use in pricing the asset or liability and are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the entity’s own assumptions based on market data and the entity’s judgments about the assumptions that market participants would use in pricing the asset or liability and are to be developed based on the best information available in the circumstances. The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities:

●

Level 1—Assets and liabilities with unadjusted, quoted prices listed on active market exchanges. Inputs to the fair value measurement are observable inputs, such as quoted prices in active markets for identical assets or liabilities.

●

Level 2—Inputs to the fair value measurement are determined using prices for recently traded assets and liabilities with similar underlying terms, as well as direct or indirect observable inputs, such as interest rates and yield curves that are observable at commonly quoted intervals.

●

Level 3—Inputs to the fair value measurement are unobservable inputs, such as estimates, assumptions, and valuation techniques when little or no market data exists for the assets or liabilities.

Income Taxes

The Company accounts for income taxes under ASC 740 Income Taxes (“ASC 740”). ASC 740 requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the financial statement and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carry forwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized.

ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim period, disclosure and transition. Based on the Company’s evaluation, it has been concluded that there are no significant uncertain tax positions requiring recognition in the Company’s financial statements.

The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of March 31, 2026. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

There is currently no taxation imposed on income by the Government of the Cayman Islands. In accordance with Cayman Islands federal income tax regulations, income taxes are not levied on the Company. The Company’s Canadian subsidiaries were formed for purposes of facilitating the proposed business combination and have not commenced substantive operations. As a result, the Company does not expect material Canadian income tax expense associated with such subsidiaries. Consequently, income taxes are not reflected in the Company’s financial statements.

Share-based compensation

The Company recognizes compensation costs resulting from the issuance of share-based awards to directors as an expense in the financial statements over the requisite service period based on a measurement of fair value for each share-based award. The fair value is amortized as compensation cost on a straight-line basis over the requisite service period of the awards. The Black-Scholes-Merton option-pricing model includes various assumptions, including the fair value of the estimated stock price of the Company, expected life of shares, the expected volatility and the expected risk-free interest rate, among others. These assumptions reflect the Company’s best estimates, but they involve inherent uncertainties based on market conditions generally outside the control of the Company.

Segment Reporting

ASC Topic 280, “Segment Reporting,” establishes standards for companies to report in their financial statement information about operating segments, products, services, geographic areas, and major customers. Operating segments are defined as components of an enterprise for which separate financial information is available that is regularly evaluated by the Company’s chief operating decision maker, or group, in deciding how to allocate resources and assess performance.

When evaluating the Company’s performance and making key decisions regarding resource allocation, the CODM reviews several key metrics, formation and operational costs and interest earned on cash and investments held in Trust Account which are included in the accompanying consolidated statements of operations.

The key measures of segment profit or loss reviewed by our CODM are interest earned on demand deposits in Trust Account and general and administrative expenses. The CODM reviews interest earned on demand deposits in Trust Account to measure and monitor stockholder value and determine the most effective strategy of investment with the Trust Account funds while maintaining compliance with the trust agreement. Formation and operational costs are reviewed and monitored by the CODM to manage and forecast cash to ensure enough capital is available to complete a business combination within the business combination period. The CODM also reviews formation and operational costs to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget.

Recent Accounting Pronouncements

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 amendments also introduce a disclosure principle requiring entities to disclose material events and changes occurring since the most recent annual reporting period. 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 condensed financial statements and related disclosures.

Management does not believe that any other recently issued, but not effective, accounting standards, if currently adopted, would have a material effect on the Company’s financial statements.

Note 3 — Initial Public Offering

On July 3, 2024, the Company sold 5,000,000 Units, at a price of $10.00 per Unit. Each Unit consists of one Class A ordinary share, par value $0.0001 per share and one right (the “Public Right”). Each Public Right entitles the holder to purchase one-fifth (1/5) of one Class A ordinary share upon the consummation of the Company’s initial Business Combination. The Company will not issue fractional shares. As a result, the holder must hold public rights in multiples of five (5) in order to receive shares for all of their public rights upon closing of a Business Combination. The Company had also granted the underwriters a 45-day option to purchase up to an additional 750,000 units to cover over-allotments, if any. On July 3, 2024, the underwriter notified the Company of its exercise of Over-Allotment Option in full to purchase additional 750,000 Option Units of the Company. On July 8, 2024, 750,000 Option Units were sold to the underwriter at an offering price of $10.00 per Option Unit, generating gross proceeds of $7,500,000.

Note 4 — Private Placement

Simultaneously with the closing of the IPO, the Sponsor purchased an aggregate of 216,750 Initial Private Placement Units at a price of $10.00 per Initial Private Placement Unit for an aggregate purchase price of $2,167,500. Each Initial Private Placement Unit was identical to the Public Units sold in the IPO, except as described below. Simultaneously with the closing of the Option Units on July 8, 2024, the Company consummated the sale of additional 11,250 Private Placement Units to the Sponsor at a price of $10.00 per Additional Private Placement Unit, generating total proceeds of $112,500.

There will be no redemption rights or liquidating distributions from the Trust Account with respect to the Founder Shares (as defined below), the Class A ordinary shares included in the Private Units (the “Private Shares”) or private placement rights. The rights will expire worthless if the Company does not consummate a Business Combination by the Combination Period.

Each Private Unit is identical to the Public Units sold in the IPO, except that it will not be redeemable, transferable, assignable or salable by the Sponsor until the completion of its initial Business Combination, except in each case (a) to the Company’s officers or directors, any affiliates or family members of any of its officers or directors, any members of the Sponsor, or any affiliates of the Sponsor, (b) in the case of an individual, by gift to a member of the individual’s immediate family or to a trust, the beneficiary of which is a member of the individual’s immediate family or an affiliate of such person, or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) in the event of the Company’s liquidation prior to the completion of its initial Business Combination; or (f) by virtue of the laws of the Cayman Islands or the Sponsor’s operating agreement upon dissolution of the Sponsor; provided, however, that in the case of clauses (a) through (e) or (f) these permitted transferees must enter into a written agreement agreeing to be bound by these transfer restrictions and by the same agreements entered into by the Sponsor with respect to such securities (including provisions relating to voting and liquidation distributions).

Note 5 — Related Party Transactions

Founder Shares

On July 4, 2023 and September 29, 2023, the Sponsor acquired 100 and 1,437,400 Class B ordinary shares (the “Founder Shares”), respectively, for an aggregate purchase price of $25,000, or approximately $0.02 per share. As of March 31, 2026, there were 1,437,500 Founder Shares issued and outstanding, among which, up to 187,500 Founder Shares were subject to forfeiture if the underwriters’ over-allotment was not exercised. On July 8, 2024, the underwriters exercised their Over-Allotment Option in full, hence, all 187,500 Founder Shares were no longer subject to forfeiture.

The Founder Shares are identical to the Class A ordinary shares included in the Public Units sold in the IPO, and holders of Founder Shares have the same shareholder rights as public shareholders, except that (i) holders of the Founder Shares have the right to vote on the election of directors prior to its initial Business Combination, (ii) the Founder Shares are subject to certain transfer restrictions, as described in more detail below, and (iii) the Sponsor, officers and directors of the Company have entered into a letter agreement with the Company, pursuant to which they have agreed (A) to waive their redemption rights with respect to the Founder Shares, Private Shares and public shares in connection with the completion of its initial Business Combination and (B) to waive their rights to liquidating distributions from the Trust Account with respect to the Founder Shares and Private Shares if the Company fails to complete its initial Business Combination by July 3, 2026 (if the Company fully extends the period of time to consummate a Business Combination), although they will be entitled to liquidating distributions from the Trust Account with respect to any public shares they hold if the Company fails to complete its initial Business Combination within such time period and (iii) the Founder Shares and Private Shares are subject to registration rights. If the Company submits its initial Business Combination to its public shareholders for a vote, the Sponsor, and its officers and directors have agreed (and their permitted transferees will agree), pursuant to the terms of a letter agreement entered into with the Company, to vote any Founder Shares and the Private Shares held by them and any public shares purchased during or after the IPO in favor of its initial Business Combination.

The Class B ordinary shares will automatically convert into Class A ordinary shares at the time of its initial Business Combination on a one-for-one basis, subject to adjustment for share splits, share capitalizations, reorganizations, recapitalizations and the like, and subject to further adjustment as provided herein and in its amended and restated memorandum and articles of association. In the case that additional Class A ordinary shares, or equity-linked securities, are issued or deemed issued in excess of the amounts sold in the IPO and related to the closing of the Business Combination, the ratio at which Class B ordinary shares shall convert into Class A ordinary shares will be adjusted (unless the holders of a majority of the issued and outstanding Class B ordinary shares agree to waive such anti-dilution adjustment with respect to any such issuance or deemed issuance) so that the number of Class A ordinary shares issuable upon conversion of all Class B ordinary shares will equal, in the aggregate, 20% of the sum of all ordinary shares outstanding upon completion of the IPO (excluding the Private Shares and the Representative Shares) plus all Class A ordinary shares and equity-linked securities issued or deemed issued in connection with the Business Combination (excluding any shares or equity-linked securities issued, or to be issued, to any seller in the initial Business Combination or any private placement-equivalent units issued to its sponsor or its affiliates upon conversion of loans made to the Company). Holders of Founder shares may also elect to convert their Class B ordinary shares into an equal number of Class A ordinary shares, subject to adjustment as provided above, at any time. The term “equity-linked securities” refers to any debt or equity securities that are convertible, exercisable or exchangeable for its Class A ordinary shares issued in a financing transaction in connection with its initial Business Combination, including but not limited to a private placement of equity or debt. Securities could be “deemed issued” for purposes of the conversion adjustment if such shares are issuable upon the conversion or exercise of convertible securities, warrants or similar securities.

With certain limited exceptions, the Founder Shares are not transferable, assignable or saleable (except to the permitted transferees, each of whom will be subject to the same transfer restrictions) until the earlier of (1) six months after the completion of its initial Business Combination and (2) the date on which the Company consummates a liquidation, merger, share exchange, reorganization, or other similar transaction after its initial Business Combination that results in all of its shareholders having the right to exchange their ordinary shares for cash, securities or other property. Notwithstanding the foregoing, if the last sale price of the Company ordinary shares equals or exceeds $12.00 per share (as adjusted for share splits, share capitalizations, rights issuances, subdivisions, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period after the Company’s initial Business Combination, 50% of the Founder shares will be released from the lock-up.

Due to Related Party

The Sponsor funded part of the Company’s transaction costs related to the business combination. As of March 31, 2026 and September 30, 2025, $50,000 and nil, respectively, were outstanding. The amount is unsecured, interest-free and due on demand.

Promissory Note — Related Party

On September 30, 2023, the Sponsor agreed to loan the Company up to $500,000 (the “Promissory Note”) to be used for a portion of the expenses of the IPO. This loan is non-interest bearing, unsecured and is due at the earlier of (1) the closing of the IPO or (2) the date on which the Company determines not to conduct an initial public offering of its securities, unless accelerated upon the occurrence of an Event of Default. The outstanding loan balance of $481,511 was repaid upon the closing of the IPO out of the offering proceeds not held in the Trust Account on July 3, 2024.

On August 4, 2025, September 3, 2025, October 6, 2025, November 4, 2025, December 4, 2025, January 2, 2026, and February 4, 2026 in relation to the Sponsor’s payment of the Monthly Extension Fee, the Company issued seven unsecured promissory notes (“Extension Notes”) to the Sponsor, amounting to a total of $1,050,000. Each Extension Note has a principal sum of $150,000, bears no interest and is payable in full upon the earlier to occur of (i) the consummation of the Company’s 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 the Conversion Units 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.

There were $1,050,000 and $300,000 Extension Notes outstanding as of March 31,2026 and September 30, 2025 respectively.

Working Capital Loans

In addition, in order to finance transaction costs in connection with an intended initial Business Combination, the Sponsor, the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required. If the Company completes the initial Business Combination, it would repay such loaned amounts. In the event that the initial Business Combination does not close, the Company may use a portion of the working capital held outside the Trust Account to repay such loaned amounts but no proceeds from the Trust Account would be used for such repayment. Up to $1,500,000 of such working capital loans (“Working Capital Loans”) made by the Sponsor, the Company’s officers and directors, or the Company’s or their affiliates to the Company prior to or in connection with its initial Business Combination may be convertible into units, at a price of $10.00 per unit at the option of the lender, upon consummation of its initial Business Combination. The units would be identical to the Private Units.

On August 25, 2025 and January 6, 2026, the Company issued two unsecured promissory note (the “Working Capital Note”) in the principal amount of up to $300,000 each note 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 Note bears no interest and is payable in full upon the earlier to occur of (i) the consummation of the Company’s 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 Working Capital Note, in whole or in part, respectively, into Conversion Units 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.

As of March 31, 2026 and September 30, 2025, the Company had $500,000 and $200,000 outstanding under the Working Capital Note.

Administrative Support Services

Commencing on the effective date of the registration statement of the IPO, the Company has agreed to pay an affiliate of the Sponsor a total of $10,000 per month for office space, utilities and secretarial and administrative support. Upon completion of its initial Business Combination or its liquidation, the Company will cease paying these monthly fees. The Company incurred $60,000 and $60,000 for the six months ended March 31, 2026 and 2025, respectively, and $30,000 and $30,000 for the six months ended March 31, 2026 and 2025, respectively. As of March 31, 2026 and September 30, 2025, the unpaid balance of administrative support service fee was $110,000 and $50,000, respectively, which were included in the balance of amount due to related party.

Note 6 — Commitments and Contingencies

Registration Rights

The holders of Founder Shares, Representative Shares, Private Units, and units that may be issued on conversion of Working Capital Loans (and in each case holders of their component securities, as applicable) are entitled to registration rights pursuant to a registration rights agreement on July 2, 2024 requiring the Company to register such securities for resale. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company registers such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to its completion of its initial Business Combination and rights to require the Company to register for resale such securities pursuant to Rule 415 under the Securities Act. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

The Company had granted the underwriter a 45-day option from the date of IPO to purchase up to an additional 750,000 Option Units to cover over-allotments, if any. On July 8, 2024, the underwriters exercised the Over-Allotment Option in full.

The underwriter was entitled to a cash underwriting discount of $0.15 per unit, or $750,000 (or up to $862,500 if the underwriters’ over-allotment is exercised in full). Additionally, the underwriter was entitled to acquire the Company’s 200,000 Class A ordinary shares (or up to 230,000 shares of Class A ordinary shares if the underwriters’ over-allotment is exercised in full) that were registered in the IPO and were paid at the closing of the IPO as the Representative Shares. In addition, the underwriter has agreed (i) to waive its redemption rights with respect to such shares in connection with the completion of its initial Business Combination and (ii) to waive its rights to liquidating distributions from the Trust Account with respect to such shares if the Company fails to complete its initial Business Combination within the Combination Period. In connection with the IPO, the Company issued 200,000 Representative Shares to the underwriter with a fair value of $262,000. In connection with the issuance and sales of the Option Units, the Company issued an additional 30,000 Representative Shares to the underwriter with a fair value of $39,000.

Advisory Agreements

The Company has entered into several agreements with financial advisors in connection with identifying and consulting with the Company with respect to the potential acquisition targets. Any fees under these agreements are only earned by the financial advisors, and do not become due and payable to them until the Company completes an initial Business Combination with a target identified by that financial advisor. As of the financial statements issue date, the Company has determined that the possibility of the business combination with any potential target identified by a financial advisor is not probable.

Note 7 — Shareholders’ Equity

Preference Share — The Company is authorized to issue 10,000,000 preference shares, $0.0001 par value, with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. As of March 31, 2026 and September 30, 2025, there were no preference shares issued or outstanding.

Class A Ordinary Share — The Company is authorized to issue 390,000,000 Class A ordinary shares with $0.0001 par value. There were 458,000 Class A ordinary shares issued or outstanding, excluding 2,930,233 Class A ordinary shares subject to possible redemption as of March 31, 2026 and September 30, 2025.

Class B Ordinary Share — The Company is authorized to issue 100,000,000 Class B ordinary shares with $0.0001 par value. In July 2023 and September 2023, the Company issued an aggregate of 1,437,500 Founder Shares to the Sponsor for an aggregate purchase price of $25,000, or approximately $0.02 per share, of which an aggregate of up to 187,500 shares were subject to forfeiture for no consideration to the extent that the underwriter’s over-allotment option was not exercised in full or in part, so that the initial shareholder would collectively own 20% of the Company’s issued and outstanding ordinary shares after the IPO (assuming they do not purchase any Units in the IPO and excluding the Class A ordinary shares underlying the Placement Units). As a result of the underwriters’ exercise of their over-allotment option in full on July 8, 2024, all 187,500 Class B ordinary shares were no longer subject to forfeiture. As of March 31, 2026 and September 30, 2025, there were 1,437,500 Class B ordinary shares issued and outstanding,

Prior to the initial Business Combination, only holders of Class B ordinary shares will have the right to vote in the election of directors. Holders of its Class A ordinary shares will not be entitled to vote on the election of directors during such time. These provisions of the Company’s amended and restated memorandum and articles of association with class rights may not be amended without a resolution passed by holders of at least two thirds of the Company’s ordinary shares who are eligible to vote and attend and vote in a general meeting of the Company’s shareholders. With respect to any other matter submitted to a vote of its shareholders, including any vote in connection with the initial Business Combination, except as required by law, holders of the Founder Shares and holders of its Class A ordinary shares will vote together as a single class, with each share entitling the holder to one vote.

The Class B ordinary shares will automatically convert into Class A ordinary shares at the time of the initial Business Combination, or earlier at the option of the holder, on a one-for-one basis, subject to adjustment pursuant to the Company’s amended and restated memorandum and articles of association, as more fully described in Note 5.

Rights

Each holder of a right will receive one-fifth (1/5) of one Class A ordinary share upon consummation of its initial Business Combination, even if the holder of such right redeemed all Class A ordinary shares held by it in connection with the initial Business Combination. No additional consideration will be required to be paid by a holder of rights in order to receive its additional shares upon consummation of an initial Business Combination, as the consideration related thereto has been included in the unit purchase price paid for by investors in the IPO. If the Company enters into a definitive agreement for a Business Combination in which the Company will not be the surviving entity, the definitive agreement will provide for the holders of rights to receive the same per share consideration the holders of the Class A ordinary shares will receive in the transaction on an as-converted into ordinary share basis, and each holder of a right will be required to affirmatively convert its rights in order to receive the one-fifth (1/5) share underlying each right (without paying any additional consideration) upon consummation of the Business Combination. More specifically, the right holder will be required to indicate its election to convert the rights into underlying shares as well as to return the original rights certificates to the Company.

The shares issuable upon conversion of the rights will be freely tradable (except to the extent held by affiliates of the Company). The Company will not issue fractional shares upon conversion of the rights. Fractional shares will either be rounded down to the nearest whole share or otherwise addressed in accordance with the applicable provisions of Cayman law. As a result, the holders of rights must hold rights in multiples of five (5) in order to receive shares for all of their rights upon closing of a Business Combination. If the Company is unable to complete an initial Business Combination within the required time period and the Company liquidates the funds held in the Trust Account, holders of rights will not receive any of such funds with respect to their rights, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with respect to such rights, and the rights will expire worthless. Further, there are no contractual penalties for failure to deliver securities to the holders of the rights upon consummation of an initial Business Combination. Accordingly, the rights may expire worthless. As of March 31, 2026, there were a total of 5,978,000 rights outstanding, which can be converted into 1,195,600 Class A ordinary share upon consummation of the initial Business Combination.

Note 8 — Segment Information

ASC Topic 280, “Segment Reporting,” establishes standards for companies to report in their financial statements information about operating segments, products, services, geographic areas, and major customers. Operating segments are defined as components of an enterprise for which separate financial information is available that is regularly evaluated by the Company’s chief operating decision maker, or group, in deciding how to allocate resources and assess performance. The Company has adopted the guidance in ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, in the accompanying financial statements.

The Company’s chief operating decision maker has been identified as the Chief Executive Officer (“CODM”), who reviews the operating results for the Company as a whole to make decisions about allocating resources and assessing financial performance. Accordingly, management has determined that the Company only has one operating and reportable segment. When evaluating the Company’s performance and making key decisions regarding resource allocation the CODM reviews key metrics, which include the following:

	For the Three Months Ended March 31,				For the Six Months Ended March 31,
	2026		2025		2026		2025
General and administrative expenses	$	123,500	$	186,727	$	541,142	$	338,765
Interest earned on investments held in Trust Account	$	272,856	$	594,603	$	572,209	$	1,288,659

The key measures of segment profit or loss reviewed by the CODM are general and administrative expenses and interest earned on investments held in Trust Account. General and administrative expenses are reviewed and monitored by the CODM to manage and forecast cash to ensure enough capital is available to complete a business combination within the business combination period. The CODM also reviews general and administrative expenses to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget. Interest earned on investments held in Trust Account are reviewed to measure and monitor shareholder value and determine the most effective strategy of investment with the Trust Account funds while maintaining compliance with the trust agreement.

Note 9 —Loan from Marine Thinking (the “Target”)

On March 3, 2026, in relation to the Marine Thinking’s payment of the Monthly Extension Fee, the Company issued a Target Extension Note to the Target in a principal sum of $150,000. The Target Extension Note bears no interest and is payable in full upon the earlier to occur of (i) the consummation of the Company’s Business Combination or (ii) the date of expiry of the term of the Company. The has the right, but not the obligation, to convert the Extension Note, in whole or in part, respectively, into the Conversion Units 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. As of March 31, 2026 and December 31, 2025, there were $150,000 and $0 outstanding, respectively.

On March 31, 2026, the Company received $150,000 from the Target to be used for the payment of the Monthly Extension Fee. The amount was deposited into the Trust Account on April 2, 2026, and recorded as Due to third party – Marine Thinking (target company) on the accompanying unaudited condensed consolidated balance sheet.

Note 10 — Subsequent Events

The Company evaluated subsequent events and transactions that occurred after the balance sheet date through the date when these unaudited condensed consolidated financial statements were issued. Based on this review, the Company identified the following subsequent events that would require adjustment or disclosure in the financial statements.

Promissory Note – Monthly Extension

On April 2, 2026, the Monthly Extension Fee in the amount of $150,000 was deposited into the Trust Account for the public shareholders, which enables the Company to extend the period of time it has to consummate its initial business combination by one from April 3, 2026 to May 3, 2026. On May 4, 2026, the Monthly Extension Fee in the amount of $150,000 was deposited into the Trust Account for the public shareholders, which enables the Company to extend the period of time it has to consummate its initial business combination by one from May 3, 2026 to June 3, 2026. The two Monthly Extension Fees were paid by the Target, and accordingly, the Company issued two Extension Notes to the Target, each in the principal amount of $150,000 on April 6, 2026 and May 4, 2026, in connection with the payment of Monthly Extension Fee, respectively.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Forward-Looking Statements

This Quarterly Report on Form 10-Q includes forward-looking statements. We have based these forward-looking statements on our current expectations and projections about future events. These forward-looking statements are subject to known and unknown risks, uncertainties and assumptions about us that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by such forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as “may,” “should,” “could,” “would,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “continue,” or the negative of such terms or other similar expressions. Factors that might cause or contribute to such a discrepancy include, but are not limited to, those described in our other Securities and Exchange Commission (“SEC”) filings. References to the “Company”, “us,” “our,” or “we” refer to Eureka Acquisition Corp. The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited condensed consolidated financial statements and related notes herein.

Overview

We are a blank check company formed under the laws of Cayman Island on June 13, 2023, for the purpose of entering into a merger, share exchange, asset acquisition, share purchase, recapitalization, reorganization or similar business combination with one or more businesses or entities, which we refer to as a “target business.” Our efforts to identify a prospective target business will not be limited to a particular industry or geographic location but will initially focus in Asia.

We presently have no revenue, have had losses since inception from incurring formation and operating costs and have had no operations other than identifying and evaluating suitable acquisition transaction candidates. We have relied upon the working capital available to us following the consummation of the initial public offering (the “IPO”) and the private placement to fund our operations, as well as the funds loaned by our sponsor, Hercules Capital Management Corp (the “Sponsor”), our officers, directors or their affiliates. We expect to continue to incur significant costs in the pursuit of our acquisition plans. We cannot assure you that our plans to raise capital or to complete our initial business combination will be successful.

June 2025 Shareholder Meeting

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

In connection with the Extraordinary General Meeting, 2,819,767 Class A ordinary shares, par value $0.0001 per share, of the Company (the “Class A Ordinary Shares”) were rendered for redemption, and approximately $29 million was released from the Trust Account (as defined below) to pay such redeeming shareholders.

Trust Amendment

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 of the Company (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.

Extensions and Extension Notes

Pursuant to the Current Charter, the Company currently has until June 3, 2026 (or up to July 3, 2026 if fully extended) to complete its business combination (the “Combination Period”). If the Company is unable to complete its initial Business Combination by the Combination Period, the Company will: (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable) divided by the number of then outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of its remaining shareholders and its Board of Directors, liquidate and dissolve, subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to its public rights or private placement rights, which will expire worthless if the Company fails to complete its initial Business Combination by the Combination Period.

Nasdaq Noncompliance Letter

On April 6, 2026, the Company received written notice (the “Notice”) from the Listing Qualifications Staff of the Nasdaq Stock Market LLC (“Nasdaq”) indicating that the Company no longer complies with the Nasdaq Capital Market continued listing criteria set forth in Listing Rule 5550(a)(3) (the “Minimum Public Holders Rule”), which requires the Company to maintain a minimum of 300 public holders for continued listing on Nasdaq. The Notice is only a notification of deficiency, not of imminent delisting, and has no current effect on the listing or trading of the Company’s securities on the Nasdaq.

The Notice states that the Company has 45 calendar days, or until May 21, 2026, to submit a plan to regain compliance with the Minimum Public Holders Rule. If the Company is unable to regain compliance by that date, the Company intends to submit a plan to regain compliance with the Minimum Public Holders Rule within the required timeframe. If Nasdaq accepts the Company’s compliance plan, then Nasdaq may grant the Company an extension of up to180 calendar days from the date of the Notice to evidence compliance. If Nasdaq does not accept the Company’s plan, then the Company will have the opportunity to appeal that decision to a Nasdaq Hearings Panel.

Results of Operations and Known Trends or Future Events

We have neither engaged in any operations nor generated any revenues to date. Our only activities since inception have been organizational activities as well as activities related to the IPO, searching for targets to complete a business combination and preparing the Transactions. Following the IPO, we will not generate any operating revenues until after the completion of a business combination, at the earliest. We will generate non-operating income in the form of dividend and/or interest income from the proceeds derived from the IPO and sale of Private Units. Since the completion of the IPO, we expect to incur increased expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for expenses associated with the search for target opportunities.

For the three months ended March 31, 2026, we had a net income of $149,356, which consisted of general and administrative expenses of $123,500 offset by interest income from the Trust Account of $272,856.

For the three months ended March 31, 2025, we had a net income of $407,876, which consisted of interest income from the Trust Account”) of $594,603, partially offset by general and administrative expenses of $186,727.

For the six months ended March 31, 2026, we had a net income of $31,067, which consisted of interest income from the Trust Account of $572,209, partially offset by general and administrative expenses of $541,142. Cash used in operating activities was $399,809. Changes in operating assets and liabilities provided $141,333 of cash for operating activities.

For the six months ended March 31, 2025, we had a net income of $949,894, which consisted of interest income from the Trust Account of $1,288,659, partially offset by general and administrative expenses of $338,765. Cash used in operating activities was $315,590. Changes in operating assets and liabilities provided $23,175 of cash for operating activities.

Liquidity and Capital Resources

As of March 31, 2026, we had cash of $151,622 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.

If our estimates of the costs of undertaking in-depth due diligence and negotiating our initial business combination are less than the actual amount necessary to do so, we may have insufficient funds available to operate our business prior to our initial business combination. Moreover, we may need to obtain additional financing either to consummate our initial business combination or because we become obligated to redeem a significant number of our public shares upon consummation of our initial business combination, in which case we may issue additional securities or incur debt in connection with such business combination. Subject to compliance with applicable securities laws, we would only consummate such financing simultaneously with the consummation of our initial business combination. Following our initial business combination, if cash on hand is insufficient, we may need to obtain additional financing in order to meet our obligations.

As of March 31, 2026, the Company had $151,622 of cash and a working capital deficit of $2,066,415. 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 July 3, 2026 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 audited consolidated financial statements do not include any adjustments that might result from the Company’s inability to continue as a going concern.

Off-Balance Sheet Financing Arrangements

We have no obligations, assets or liabilities that would be considered off-balance sheet arrangements as of March 31, 2026. We do not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. We have not entered into any off-balance sheet financing arrangements, established any special purpose entities, guaranteed any debt or commitments of other entities, or purchased any non-financial assets.

Contractual Obligations

As of March 31, 2026, we do not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities.

The founder shares, the Class A Ordinary Shares included in the Private Units, and any Class A Ordinary Shares that may be issued upon conversion of working capital loans and extension loans (and any underlying securities) will be entitled to registration rights pursuant to a registration and shareholder rights agreement entered into in connection with the IPO. The holders of these securities are entitled to make up to three demands, excluding short form demands, that we register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to our completion of our initial business combination. We will bear the expenses incurred in connection with the filing of any such registration statements.

Critical Accounting Estimates

In preparing these unaudited condensed consolidated financial statements in conformity with U.S. 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 financial statements and the reported expenses during the reporting period.

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 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.

Recent Accounting Pronouncements

Management does not believe that any other recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on our financial statements.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

As a smaller reporting company, we are not required to make disclosures under this Item.

Item 4. Controls and Procedures

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer and principal financial and accounting officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the quarter ended March 31, 2026, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on this evaluation, our principal executive officer and our principal financial and accounting officer have concluded that during the period covered by this report, our disclosure controls and procedures were effective.

Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial and accounting officer or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting during the quarter ended March 31, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

We are not currently a party to any material litigation or other legal proceedings brought against us. We are also not aware of any legal proceeding, investigation or claim, or other legal exposure that has a more than remote possibility of having a material adverse effect on our business, financial condition or results of operations.

Item 1A. Risk Factors

Not applicable to a smaller reporting company. However, factors that could cause our actual results to differ materially from those in this Quarterly Report are any of the risks described in the prospectus of our IPO (File No. 333-277780) and our annual report on Form 10-K for the fiscal year ended September 30, 2025 (the “Annual Report”) as filed with the SEC on December 15, 2025. Any of these factors could result in a significant or material adverse effect on our results of operations or financial condition. Additional risk factors not presently known to us or that we currently deem immaterial may also impair our business or results of operations. As of the date of this Quarterly Report, there have been no material changes to the risk factors disclosed in our prospectus and Annual Report.
