REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors of

Quantumsphere Acquisition Corporation

Opinion on the Financial Statements

We have audited the accompanying balance sheet of Quantumsphere Acquisition Corporation (the “Company”) as of August 7, 2025, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of August 7, 2025, in conformity with accounting principles generally accepted in the United States of America.

Explanatory Paragraph – Going Concern

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As more fully described in Note 1 to the financial statements, the Company is a Special Purpose Acquisition Company that was formed for the purpose of completing a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses within an expected period of eighteen months from the date of a successful completed proposed initial public offering. The Company lacks the capital resources it needs to fund its operations for a reasonable period of time, which is generally considered to be one year from the issuance of the financial statements. These matters raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

QUANTUMSPHERE ACQUISITION CORPORATION

NOTES TO FINANCIAL STATEMENT

AUGUST 7, 2025

Note 1 — Organization, Business Operations

Quantumsphere Acquisition Corporation (the “Company”) is a blank check company incorporated under the laws of the Cayman Islands with limited liability on July 23, 2024. The Company was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (“Business Combination”). The Company is not limited to a particular industry or sector for purposes of consummating a Business Combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.

As of August 7, 2025, the Company had not commenced any operations. For the period from July 23, 2024 (inception) through August 7, 2025, the Company’s efforts have been limited to organizational activities as well as activities related to completing the initial public offering (“IPO”). 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 Placement Units (as defined below). The Company has selected March 31 as its fiscal year end.

The Company’s sponsor is Whiteowl Holdings LLC (the “Sponsor”), a Delaware limited liability company. The Company’s ability to commence operations is contingent upon obtaining adequate financial resources through the IPO (see Note 3) and Private Placement (as defined below) to the initial shareholder (see Note 4).

The registration statement for the IPO was declared effective on August 5, 2025. On August 7, 2025, the Company consummated its IPO of 8,280,000 units (the “Public Units’), including the full exercise of the over-allotment option of 1,080,000 Units granted to the underwriters. The Public Units were sold at an offering price of $10.00 per unit generating gross proceeds of $82,800,000. Simultaneously with the IPO, the Company sold to its Sponsor 228,650 units at $10.00 per unit (the “Private Units”) in a private placement generating total gross proceeds of $2,286,500, which is described in Note 4.

Transaction costs amounted to $4,459,070 consisting of $3,898,500 of underwriting commissions, $586,500 of which was paid in cash at the closing date of the IPO, and $560,570 of legal and other offering costs. At the IPO date, cash of $902,598 was held outside of the Trust Account (as defined below) and is available for working capital purposes.

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 must complete a Business Combination having an aggregate fair market value of at least 80% of the assets held in the Trust Account (as defined below) (excluding the deferred underwriting commissions and taxes payable on interest earned on the Trust Account) at the time of the agreement to enter into an initial Business Combination. 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 it not to be required to register as an investment company under the Investment Company Act 1940, as amended (the “Investment Company Act”).

Upon the closing of the IPO, management has agreed that at least $10.00 per public share underlying Units sold in the IPO will be held into 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 certain conditions under Rule 2a-7 under the Investment Company Act of 1940 and which invest solely in U.S. Treasuries. The Trust Fund will be deposited into the Trust Account in the U.S. to be released only in the event of either: (i) the consummation of a Business Combination or (ii) the Company’s failure to complete a Business Combination within the applicable period of time.

F-4

The Company will provide its holders of the outstanding Public Shares (the “Public shareholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a 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 decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Shareholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially $10.00 per Public Share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its franchise and income tax obligations). The Public Shares subject to redemption was recorded at a redemption value and classified as temporary equity upon the completion of the IPO on August 7, 2025 in accordance with the Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.”

If the Company seeks shareholder approval, a majority of the shares voted are voted in favor of the Business Combination. If a shareholder vote is not required by law and the Company does not decide to hold a shareholder vote for business or other legal reasons, the Company will, pursuant to its amended and restated memorandum and articles of association, conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, shareholder approval of the transaction is required by law, or the Company decides to obtain shareholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. Additionally, each public shareholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. If the Company seeks shareholder approval in connection with a Business Combination, the Company’s Sponsor and any of the Company’s officers or directors that may hold Founder Shares (as defined in Note 5) (the “Initial Shareholders”) and the underwriters have agreed (a) to vote their Founder Shares, Private Shares (as defined in Note 4), and any Public Shares purchased during or after the IPO (other than Public Shares purchased outside of a redemption offer which may not be voted in favor of approving the business combination transaction in accordance with the requirements of Rule 14e-5 under the Exchange Act and any SEC interpretations or guidance relating thereto) in favor of approving a Business Combination and (b) not to convert any shares (including the Founder Shares) in connection with a shareholder vote to approve, or sell the shares to the Company in any tender offer in connection with, a proposed Business Combination.

Notwithstanding the foregoing, if the Company seeks shareholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the amended and restated memorandum and articles of association provides that a public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% or more of the Public Shares, without the prior consent of the Company.

The Initial Shareholders have agreed (a) to waive their redemption rights with respect to the Founder Shares, Private Shares, and Public Shares held by them in connection with the completion of a Business Combination and (b) not to propose, or vote in favor of, an amendment to the amended and restated memorandum and articles of association that would affect the substance or timing of the Company’s obligation to redeem 100% of its Public Shares if the Company does not complete a Business Combination, unless the Company provides the public shareholders with the opportunity to redeem their Public Shares in conjunction with any such amendment.

The Company have 18 months from the consummation of the IPO, or February 7, 2027, to consummate its initial business combination (“Combination Period”). If the Company is unable to complete a Business Combination within 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 liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

F-5

The Sponsor and the other Initial Shareholders have agreed 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 a Business Combination within the Combination Period. However, if the Sponsor or the other Initial Shareholders acquires Public Shares in or after the IPO, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period.

In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a vendor for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below $10.00 per public share, except as to any claims by a third party who executed a valid and enforceable agreement with the Company waiving any right, title, interest or claim of any kind they may have in or to any monies held in the Trust Account and except as to any claims under the Company’s indemnity of the underwriters of IPO against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims.

Going Concern Consideration

As of August 7, 2025, the Company had $902,598 of cash and a working capital of $1,096,147. The Company has incurred and expects to continue to incur significant costs in pursuit of the consummation of an initial Business Combination. In addition, the Company currently has until February 7, 2027 (unless the Company extends such period by amending its Amended and Restated Memorandum and Articles of Association) to consummate the initial Business Combination. If the Company does not complete a Business Combination within the prescribed timeline, the Company will trigger an automatic winding up, dissolution and liquidation pursuant to the terms of the Amended and Restated Memorandum and Articles of Association. In connection with the Company’s assessment of going concern considerations in accordance with Financial Accounting Standard Board’s Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” the Company has determined that it has incurred and expects to continue to incur significant costs in pursuit of its acquisition plans. There is no assurance that the Company’s plans to raise capital or to consummate a Business Combination will be successful within the Combination Period. The Company lacks the financial resources it needs to sustain operations for a reasonable period of time, which is considered to be one year from the date of the issuance of the financial statement. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. Therefore, management has determined that such additional conditions 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 financial statement does not include any adjustments that might result from the Company’s inability to continue as a going concern.

Note 2 — Significant accounting policies

Basis of Presentation

The accompanying financial statement is 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.

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.

F-6

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

In preparing these financial statements in conformity with U.S. GAAP, the Company’s 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, the actual results could differ significantly from those estimates.

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. The Company has cash of $902,598 and no cash equivalents as of August 7, 2025.

Cash Held in Trust Account

As of August 7, 2025, the assets held in the Trust Account, amounting to 82,800,000, were held in cash.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.

Fair Value of Financial Instruments

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

F-7

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.

●

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.

Deferred Offering Costs

The Company complies with the requirements of FASB ASC Topic 340-10-S99-1, “Other Assets and Deferred Costs – SEC Materials” (“ASC 340-10-S99”) and SEC Staff Accounting Bulletin Topic 5A, “Expenses of Offering”. Deferred offering costs were $4,459,070 consisting principally of $3,898,500 underwriting fees and $560,570 legal and other expenses that are directly related to the IPO and charged to shareholders’ equity upon the completion of the IPO.

Ordinary Shares Subject to Possible Redemption

The Company accounts for its 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 features 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 stockholders’ equity. In accordance with ASC 480-10-S99, the Company classifies the 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 8,280,000 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 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 immediately. The initial accretion and subsequent remeasurements will be treated as a deemed dividend (i.e., a reduction to retained earnings, or in absence of retained earnings, additional paid-in capital). Accordingly, as of August 7, 2025, ordinary shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders’ equity section of the Company’s balance sheet. As of August 7, 2025, the ordinary shares subject to redemption reflected in the balance sheet are reconciled in the following table:

F-8

Gross proceeds	$	82,800,000
Less:
Proceeds allocated to public share Rights		(1,904,400	)

Plus:
Remeasurement of carrying value to redemption value		6,260,911
Ordinary shares subject to possible redemption, August 7, 2025	$	82,800,000

Rights Accounting

The Company accounts for rights as either equity-classified or liability-classified instrument based on an assessment of the right’s specific terms and applicable authoritative guidance in ASC 480 and ASC 815. The assessment considers whether the rights are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the rights meet all of the requirements for equity classification under ASC 815, including whether the rights are indexed to the Company’s own ordinary shares and whether the right holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of right issuance and as of each subsequent quarterly period end date while the rights are outstanding.

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 August 7, 2025. 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. Consequently, income taxes are not reflected in the Company’s financial statement.

Recent Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, Income taxes (Topic 740): Improvements to Income Tax Disclosure (“ASU 2023-09”), which enhances the transparency and usefulness of income tax disclosures. ASU 2023-09 will be effective for fiscal years beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The Company adopted ASU 2023-09 as of March 31, 2025 and there were no significant impact.

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.

F-9

Note 3 — Initial Public Offering

On August 7, 2025, the Company sold 8,280,000 Units (including full allotment of 1,080,000 units), at a price of $10.00 per Unit. Each Unit consists of one ordinary share, par value $0.0001 per share and one right (the “Public Right”). Each Public Right entitles the holder to convert into one-seventh (1/7) of one ordinary share upon the consummation of the Company’s initial Business Combination.

Note 4 — Private Placement

Simultaneously with the closing of the IPO, the Sponsor purchased an aggregate of 228,650 Private Units at a price of $10.00 per Private Unit for an aggregate purchase price of $2,286,500. Each Private Unit was identical to the Public Units sold in the IPO, except as described below.

Each Private Unit consists of one ordinary share (“Private Share”) and one right (“Private Right”). Each Private Right will convert into convert into one-seventh (1/7) of one ordinary share upon the consummation of a Business Combination. The proceeds from the Private Units were added to the proceeds from the IPO which were deposited in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Units will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law), and the Private Units and all underlying securities will expire worthless. Private Placement Units and all underlying securities will not be transferable, assignable, or saleable until the completion of a Business Combination, subject to certain exceptions.

Note 5 — Related Party Transactions

Founder Shares

Upon the Company’s initial capitalization, the Sponsor subscribed for 2,875,000 ordinary shares of the Company. On March 9, 2025, the Company entered into a subscription agreement with the Sponsor for the purchase of 2,415,000 ordinary shares for an aggregated consideration of $25,000, or approximately $0.0104 per ordinary share. As a result, the Sponsor surrendered 460,000 ordinary shares for no consideration to the Company for the cancellation on May 6, 2025 and held the balance of 2,415,000 ordinary shares. On August 5, 2025, the Sponsor and the Company entered into the first amendment to the subscription agreement, pursuant to which the number of founder shares was increased to 2,898,000. As a result, the Sponsor currently holds 2,898,000 ordinary shares. No shares are subject to forfeiture as a result of the underwriter’s full excise of its over-allotment option on August 7, 2025.

The Initial Shareholders have agreed, subject to certain limited exceptions, not to transfer, assign or sell any of their Founder Shares for a time period ending on the date that is the earlier of (A) six months after the completion of the Company’s initial business combination or (B) the date on which the Company completes a liquidation, merger, stock exchange or other similar transaction after its initial business combination that results in all of the public shareholders having the right to exchange their shares of ordinary shares for cash, securities or other property. The Initial Shareholders also agree not to transfer any ownership interest in, except to permitted transferees, their private placement until at least 30 days following the completion of the business combination.

Advance — Related Party

Prior to the closing of the IPO, the Company provided $165,000 to the Sponsor for the purchase of a two-year Directors and Officers Liability policy with a total premium of $145,000 and a vendor retainer payment of $20,000. The total insurance premium of $145,000 is expected to be paid within ten business days.

Promissory Note — Related Party

On March 9, 2025 and July 22, 2025, the Sponsor agreed to loan the Company an aggregate amount of $200,000 and $500,000, respectively, to be used, in part, for transaction costs incurred in connection with the IPO (the “Promissory Notes”). Prior to the closing of the IPO, the Company has an outstanding loan balance of $210,000 under the Promissory Notes. The Promissory Notes are unsecured, interest-free and due on the date on which the Company closes the IPO. The loans were repaid upon the closing of the IPO out of the offering proceeds not held in the Trust Account on August 7, 2025.

F-10

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, or their affiliates/designees may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion. 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”) may be convertible into private 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 Placement Units.

As of August 7, 2025, the Company had no borrowings under the Working Capital Loans.

Administrative Services Agreement

The Company entered into an Administrative Services Agreement with the Sponsor commencing on the effective date of the registration statement of the initial public offering through the earlier of the consummation by the Company of an initial business combination or the Company’s liquidation, to pay the Sponsor a total of $15,000 per month for office space and administrative and support services. As of August 7, 2025, the Company incurred $1,451 in administrative service fees and recorded a prepayment of $18,549 as part of its prepaid expenses on the balance sheet.

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 Russia/Ukraine, Hamas/Israel 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 potential future sanctions on the world economy and the specific impact on the Company’s financial position, results of operations or ability to consummate a Business Combination are not yet determinable. The financial statement does not include any adjustments that might result from the outcome of this uncertainty.

Registration Rights

The holders of the Founder Shares issued and outstanding as of August 7, 2025, as well as the holders of the private units and any shares of the Company’s insiders, officers, directors or their affiliates may be issued in payment of working capital loans and extension loans made to the Company (and any shares of ordinary shares issuable upon conversion of the underlying the private rights), will be entitled to registration rights pursuant to an agreement to be signed prior to or on the effective date of the registration statement. The holders of a majority of these securities are entitled to make demands that the Company register such securities. Both the holders of the Founder Shares and the holders of the private units as well as shares issued in payment of working capital loans made to the Company, if applicable, will have the ability to elect to exercise these registration rights at any time after the consummation of an initial business combination. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the consummation of an initial business combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

F-11

Underwriting Agreement

The Company has granted SPAC Advisory Partners (“SAP”), the representative of the underwriters, a 45-day option from the date of the registration statement to purchase up to 1,080,000 additional Units to cover over-allotments, if any, at the IPO price less the underwriting discounts and commissions. The underwriter fully excised its over-allotment option on August 7, 2025.

The underwriter is entitled to a cash underwriting discount of 0.71% of the gross proceeds of the IPO, or $586,500 including the full excise of over-allotment option by the underwriter. In addition, the underwriter is entitled to a deferred fee of 4.0% of the gross proceeds of the IPO, or $3,312,000, which will be paid upon the closing of a Business Combination solely from amounts remaining in the Trust Account following all properly submitted shareholder redemption in connection with the consummation of the initial Business Combination and such deferred fee shall be capped at such amount so remaining in the Trust Account.

Right of First Refusal

The Company has granted SAP a right of first refusal for a period commencing from the consummation of the IPO until the earlier of (i) 10 months after the consummation of the initial business combination (or the liquidation of the Trust Account in the event that the Company fails to consummate its initial business combination within the prescribed time period) or (ii) 36 months after the consummation of the IPO in accordance with FINRA Rule 5110(g)(6)(A) to act as lead financial advisor, capital markets advisor, underwriter and/or private placement agent in connection with any initial business combination or in connection with any financing that occurs between the closing of the IPO and the date that is the earlier of (i) 10 months after the closing of the initial business combination or (ii) 36 months after the consummation of the IPO.

Note 7 — Shareholders’ Deficit

Ordinary shares — The Company is authorized to issue up to 500,000,000 ordinary shares, par value $0.0001 per share. Holders of ordinary shares are entitled to one vote for each share held on all matters to be voted on by the shareholders, except as required by law. Upon the Company’s initial capitalization, the Sponsor subscribed for 2,875,000 ordinary shares of the Company. On March 9, 2025, the Company entered into a subscription agreement with the Sponsor for the purchase of 2,415,000 ordinary shares for an aggregated consideration of $25,000, or approximately $0.0104 per ordinary share. As a result, the Sponsor surrendered 460,000 ordinary shares for no consideration to the Company for the cancellation on May 6, 2025 and held the balance of 2,415,000 ordinary shares. On August 5, 2025, the Sponsor and the Company entered into the first amendment to the subscription agreement, pursuant to which the number of founder shares was increased to 2,898,000.

As of August 7, 2025, there were 3,126,650 ordinary shares issued and outstanding, which includes (i) 2,898,000 Founder Shares, representing approximately 26% of the issued and outstanding shares after the IPO (excluding the Private Shares) and (iii) 228,650 Private Shares issued at the closing of the Initial Public Offering.

Rights — As of August 7, 2025, there were 8,280,000 Public Rights and 228,650 private rights include in the Private Units outstanding. Each holder of a right will receive one-seventh (1/7) of one ordinary share upon consummation of a Business Combination, even if the holder of such right redeemed all shares held by it in connection with a Business Combination. No fractional shares will be issued upon conversion of the rights. No additional consideration will be required to be paid by a holder of rights in order to receive its additional shares upon consummation of a 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 ordinary share consideration the holders of the ordinary shares will receive in the transaction on an as-converted into ordinary shares basis and each holder of a right will be required to affirmatively covert its rights in order to receive one share underlying each right (without paying additional consideration). The shares issuable upon conversion of the rights will be freely tradable (except to the extent held by affiliates of the Company).

F-12

If the Company is unable to complete a Business Combination within the Combination 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 a Business Combination. Additionally, in no event will the Company be required to net cash settle the rights. Accordingly, the rights may expire worthless.

Note 8 — Fair Value Measurements

The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date.

The following table presents information about the Company’s assets that are measured at fair value as of August 7, 2025 and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value:

	Level	August 7, 2025
Equity:
Fair value of Public Rights for ordinary shares subject to possible redemption allocation	3	$	1,904,400

The fair value of the rights was determined using an iterative analysis based on market comparable. The Public Rights have been classified within shareholders’ equity and will not require remeasurement after issuance. The following table presents the quantitative information regarding market assumptions used in the valuation of Public Rights:

	August 7, 2025
Fair value of common share	$	9.77
Market implied business combination likelihood		16.8	%
Fair value per share right	$	0.23

Note 9 — 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 Chairman, Chief Executive Officer and Chief Financial Officer (“CODM”), who reviews the assets, operating results and financial metrics 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. The CODM reviews the position of total assets available to assess if the Company has sufficient resources available to discharge its liabilities.

F-13

When evaluating the Company’s performance and making key decisions regarding resource allocation the CODM reviews several key metrics, which include the following:

		For the Period from April 1, 2025 to August 7, 2025
Formation and operating costs		$	52,911

The key measure of segment profit or loss reviewed by the CODM is formation and operating costs. Formation and operating costs include accounting expenses, printing expenses, and regulatory filing fees, none of which are deemed to be significant segment expenses and are reviewed in aggregate to ensure alignment with budget and contractual obligations. These expenses are monitored to manage and forecast cash available to complete a business combination within the required period.

Note 10 — Subsequent Events

The Company evaluated subsequent events and transactions that occurred after the balance sheet date through the date when these financial statements were issued. Based on this review, the Company did not identify any other subsequent events that would require adjustment or disclosure in the financial statements.
