ONEIM ACQUISITION CORP

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

MARCH 31, 2026

NOTE 1. DESCRIPTION OF ORGANIZATION, BUSINESS OPERATIONS AND GOING CONCERN

OneIM Acquisition Corp. (the “Company”) is a blank check company incorporated in the Cayman Islands on September 5, 2025. The Company was formed for the purpose of entering into a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (a “Business Combination”). The Company is not limited to a particular industry or geographic region 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 ~~September 30~~March 31, ~~2025~~2026, the Company had not commenced any operations. All activity for the period from September 5, 2025 (inception) through ~~September~~March 3031, ~~2025~~2026 relates to the Company’s formation and initial public offering (“Initial Public Offering”). 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 interest income on cash and cash equivalents from the proceeds derived from the Initial Public Offering and sale of Private Placement Units (defined below). The Company has selected December 31 as its fiscal year end.

The registration statement for the Company’s Initial Public Offering was declared effective on January 13, 2026. On January 15, 2026, the Company consummated the Initial Public Offering of 28,750,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units sold, the “Public Shares”), including 3,750,000 Units issued pursuant to the exercise of the Underwriters’ (as defined below) over-allotment option in full, generating gross proceeds of $287,500,000 (see Note 3).

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 200,000 units (the “Private Placement Units”) by and between the Company and OneIM Sponsor LLC (the “Sponsor”) at a price of $10.00 per unit, including 33,333 warrants (the “Private Placement Warrants”), generating gross proceeds of $2,000,000 (see Note 4).

Following the closing of the Initial Public Offering on January 15, 2026, an amount of $287,500,000 from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Placement Units was placed in a trust account (the “Trust Account”), to be invested only in U.S. government treasury obligations with maturities of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”), which invest only in direct U.S. government treasury obligations, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the funds held in the Trust Account, as described below.

Transaction costs related to the issuances described above amounted to $16,~~732~~687,~~695~~698, consisting of $275,000 of cash underwriting fees, $15,812,500 of deferred underwriting fees and $~~645~~600,~~195~~198 of other offering costs. In addition, at January 15, 2026, $~~833~~883,609 of cash was held by the Company outside of the Trust Account 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 Initial Public Offering and the sale of the Private Placement 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 with one or more target businesses that together have an aggregate fair market value of at least 80% of the Trust Account (excluding the amount of deferred underwriting discounts held in the Trust Account and taxes payable on the income earned on the Trust Account) at the time of the agreement to enter into the 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. Upon the closing of the Initial Public Offering, management has agreed that an amount equal to at least $10.00 per Unit sold in the Initial Public Offering, including the proceeds from the sale of the Private Placement ~~units~~Units, will be held in the Trust Account.

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 held in the Trust Account, plus any interest income earned thereon (initially anticipated to be $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 tax obligations). There will be no redemption rights upon completion of a Business Combination with respect to the Company’s warrants. The Public Shares subject to redemption will be recorded at redemption value and classified as temporary equity upon the completion of the Initial Public Offering in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480, Distinguishing Liabilities from Equity (“ASC 480”).

The Company will proceed with a Business Combination only if 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 reasons, the Company will, pursuant to its amended and restated memorandum and articles of association (the “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 other 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. If the Company seeks shareholder approval in connection with a Business Combination, the Sponsor and independent directors have agreed to vote the Founder Shares (as defined in Note 6) and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination. Additionally, each Public Shareholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction or do not vote at all.

F-6

ONEIM ~~Notwithstanding~~ACQUISITION the above, if the Company seeks shareholder approval of a Business Combination and the Company 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. CORP

~~The~~NOTES ~~Sponsor~~TO ~~and~~UNAUDITED ~~independent~~CONDENSED ~~directors~~FINANCIAL have agreed to waive redemption rights with respect to any Founder Shares held and any Public Shares they may have acquired during or after the Initial Public Offering in connection with the completion of a Business Combination, except that Public Shares held by the initial shareholders will be subject to mandatory redemption upon any diminution of the Trust Account in connection with an extension, and such shares will be entitled to redemption at a price equal to the per share redemption value then held in the Trust Account in connection therewith.STATEMENTS

~~The Company will have until January~~MARCH 1531, 2028 (or March 15, 2028), 24 months from the closing of the Initial Public Offering (or 27 months from the closing of the Initial Public Offering if the Company has executed a definitive agreement for an initial Business Combination within 24 months of the Initial Public Offering) to complete a Business Combination (the “Completion Period”). However, if the Company anticipates that it may not be able to consummate a Business Combination within 24 months (or 27 months as discussed above) from the closing of the Initial Public Offering, the Company may, but is not obligated to, by resolution of the board if requested by the initial shareholders, extend the period of time to consummate a Business Combination by seeking shareholder approval to amend the Amended and Restated Memorandum and Articles of Association to extend the date by which the Company must consummate the initial Business Combination. If the Company seeks shareholder approval for an extension, holders of Public Shares will be offered an opportunity to redeem their shares, regardless of whether they abstain, vote for, or against, the Company’s initial Business Combination, at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned thereon (which interest shall be net of amounts not previously released to the Company pursuant to permitted withdrawals), divided by the number of then issued and outstanding Public Shares, subject to applicable law. For the avoidance of doubt, the time to complete a Business Combination shall not be extended beyond 24 months (or 27 months as discussed above) without a shareholder vote. Deutsche Bank Securities Inc. (the “Underwriters”) have agreed to waive their rights to their deferred underwriting commission held in the Trust Account in the event the Company does not complete a Business Combination within the Completion Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares.2026

~~Going~~The ~~Concern~~Company ~~Consideration~~will proceed with a Business Combination only if 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 reasons, the Company will, pursuant to its amended and restated memorandum and articles of association (the “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 other 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. If the Company seeks shareholder approval in connection with a Business Combination, the Sponsor and independent directors have agreed to vote the Founder Shares (as defined in Note 6) and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination. Additionally, each Public Shareholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction or do not vote at all.

The Company will have until January 15, 2028 (or March 15, 2028), 24 months from the closing of the Initial Public Offering (or 27 months from the closing of the Initial Public Offering if the Company has executed a definitive agreement for an initial Business Combination within 24 months of the Initial Public Offering) to complete a Business Combination (the “Completion Period”). However, if the Company anticipates that it may not be able to consummate a Business Combination within 24 months (or 27 months as discussed above) from the closing of the Initial Public Offering, the Company may, but is not obligated to, by resolution of the board if requested by the initial shareholders, extend the period of time to consummate a Business Combination by seeking shareholder approval to amend the Amended and Restated Memorandum and Articles of Association to extend the date by which the Company must consummate the initial Business Combination. If the Company seeks shareholder approval for an extension, holders of Public Shares will be offered an opportunity to redeem their shares, regardless of whether they abstain, vote for, or against, the Company’s initial Business Combination, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned thereon (which interest shall be net of amounts not previously released to the Company pursuant to permitted withdrawals), divided by the number of then issued and outstanding Public Shares, subject to applicable law. For the avoidance of doubt, the time to complete a Business Combination shall not be extended beyond 24 months (or 27 months as discussed above) without a shareholder vote. Deutsche Bank Securities Inc. (the “Underwriters”) have agreed to waive their rights to their deferred underwriting commission held in the Trust Account in the event the Company does not complete a Business Combination within the Completion Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares.

In order to protect the amounts held in the Trust Account, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company have entered into a written letter of intent, confidentiality or other similar agreement or Business Combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Public Share due to reductions in the value of the Trust Account assets, in each case less taxes payable and up to $100,000 of interest to pay liquidation expenses, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the indemnity of the Underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”).

Liquidity, Capital Resources and Going Concern

As of March 31, 2026, the Company had a working capital surplus of $1,492,455. Prior to the completion of the Initial Public Offering, the Company lacked the liquidity it needed to sustain operations for a reasonable period of time, which is considered to be one year from the issuance date of the unaudited condensed financial statements. The Company has since completed its Initial Public Offering at which time capital in excess of the funds deposited in the Trust Account and/or used to fund offering expenses is available to the Company for general working capital purposes. Accordingly, management has since re-evaluated the Company’s liquidity and financial condition and determined that sufficient capital exists to sustain operations one year from the date the unaudited condensed financial statements are issued and therefore substantial doubt has been alleviated.

The Company will have until the end of the Completion Period to consummate a Business Combination. If a Business Combination is not consummated by the end of the Completion Period, there will be a mandatory liquidation and subsequent dissolution of the Company. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after January 15, 2028 (or March 15, 2028). The Company intends to complete the initial Business Combination before the mandatory liquidation date. However, there can be no assurance that the Company will be able to consummate any Business Combination by January 15, 2028 (or March 15, 2028).

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed financial ~~statement~~statements isare 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.

The accompanying unaudited condensed financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the period ended December 31, 2025, as filed with the SEC on March 30, 2026. The interim results for the three months ended March 31, 2026 are not necessarily indicative of the results to be expected for the period ending December 31, 2026 or for any future periods.

Emerging Growth Company

The Company is an “emerging growth company,” as defined in Section 2(a) of 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 independent registered public accounting firm 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-8

ONEIM ACQUISITION CORP

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

MARCH 31, 2026

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 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 a financial ~~statement~~statements in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the unaudited condensed financial ~~statement~~statements and the reported amounts of expenses and disclosure of contingent assets and liabilities 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 unaudited condensed financial ~~statement~~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 could differ 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. As of ~~September~~March 3031, 2026 and December 31, 2025, the Company ~~had~~held no cash and cash equivalents of $770,360 and $0, respectively.

~~Deferred~~Marketable ~~Offering~~Securities ~~Costs~~Held in Trust Account

~~The~~As ~~Company complies with the requirements~~ of ~~ASC~~March 31, ~~340-10-S99-1~~2026 and ~~SEC~~December 31, ~~Staff Accounting Bulletin Topic 5A~~2025, ~~Expenses~~the ofCompany ~~Offering.~~had ~~Deferred offering costs consist of legal~~$288, ~~accounting~~733,079 ~~underwriting fees~~ and ~~other~~$0 ~~costs~~in ~~incurred~~marketable ~~through~~securities ~~the~~held ~~balance~~in ~~sheet date that are directly related to~~ the ~~Initial~~Trust Public Offering. Offering costs are charged to temporary equity or permanent equity based upon the relative fair value of the proceeds received from the Units sold upon the completion of the Initial Public Offering. Offering costs are charged to temporary equity or permanent equity based upon the relative fair value of the proceeds received from the financial instruments sold upon completion of the Initial Public Offering and Private Placement. As of September 30Account, ~~2025, the Company had deferred offering costs of $196,107~~respectively.

Class A Ordinary Shares Subject to Possible Redemption

The Company’s Class A ordinary shares that were sold as part of the Units in the Initial Public Offering contain a redemption feature which allows for the redemption of such Public Shares in connection with the Company’s liquidation, if there is a shareholder vote or tender offer in connection with the Business Combination and in connection with certain amendments to the Company’s Amended and Restated Memorandum and Articles of Association. In accordance with ASC 480, conditionally redeemable Class A ordinary shares (including Class A 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) are classified as temporary equity. Ordinary liquidation events, which involve the redemption and liquidation of all of the entity’s equity instruments, are excluded from the provisions of ASC 480. Although the Company did not specify a maximum redemption threshold, its charter provides that currently, the Company will only redeem its Public Shares. However, the threshold in its Amended and Restated Memorandum and Articles of Association would not change the nature of the underlying shares as redeemable and thus the Public Shares are required to be disclosed outside of permanent equity. The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable ordinary shares to equal the redemption value at the end of each reporting period. Such changes are reflected in additional paid-in capital, or in the absence of additional paid-in capital, in accumulated deficit.

Offering Costs Associated with the Initial Public Offering

The Company complies with the requirements of ASC 340-10-S99-1 and SEC Staff Accounting Bulletin Topic 5A, Expenses of Offering. Offering costs consist principally of professional and registration fees incurred through the balance sheet date that are related to the Initial Public Offering. Offering costs directly attributable to the issuance of an equity contract to be classified in equity are recorded as a reduction in equity. Offering costs for equity contracts that are classified as assets and liabilities are expensed immediately. The Company incurred offering costs amounting to $16,687,698, consisting of $275,000 of cash underwriting fees, $15,812,500 of deferred underwriting fees and $600,198 of other offering costs. As such, the Company recorded $16,583,451 of offering costs as a reduction of temporary equity and $104,247 of offering costs as a reduction of permanent equity.

Income Taxes

The Company accounts for income taxes under ASC Topic 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~~carryforwards. 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.

~~F-8~~ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an entity’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 periods, 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 unaudited condensed financial statements.

Consequently, itincome ~~has~~taxes ~~been concluded that there~~ are nonot ~~significant~~reflected ~~uncertain tax positions requiring recognition~~ in the Company’s unaudited condensed financial ~~statement~~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 September 30, 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. The Company is considered an exempted Cayman Islands Company and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. Consequently, income taxes are not reflected in the Company’s financial statement.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist of a cash account in a financial institution which, at times, may exceed the Federal ~~depository~~Deposit ~~insurance~~Insurance ~~coverage~~Corporation 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. Any material loss that the Company may experience in the future could have an adverse effect on the Company.

ONEIM ACQUISITION CORP

Net Income per Ordinary Share

Net income per ordinary share is computed by dividing net income by the weighted average number of ordinary shares outstanding during the period. The calculation of diluted income per share does not consider the effect of the warrants issued in connection with the Initial Public Offering since the exercise of the warrants are contingent upon the occurrence of future events. The Company has two classes of ordinary shares, which are referred to as redeemable Class A ordinary shares and Class B ordinary shares. Accretion associated with the redeemable shares of Class A ordinary shares is excluded from income per ordinary share as the redemption value approximates fair value.

The Company did not have any dilutive securities or other contracts that could, potentially, be exercised or converted into ordinary shares and then share in the earnings of the Company included in redeemable Class A ordinary shares. As a result, diluted income per Class A ordinary share is the same as basic income per Class A ordinary share for the periods presented.

Class B ordinary shares includes 937,500 shares that were subject to forfeiture if the over-allotment option was not exercised in full or in part by the Underwriters (see Note 6). On January 15, 2026, the Underwriters’ over-allotment option was exercised in full simultaneously with the Initial Public Offering, and the 937,500 Class B ordinary shares were no longer subject to forfeiture.

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, Fair Value Measurement, approximates the carrying amounts represented in the accompanying condensed balance ~~sheet~~sheets, primarily due to their short-term nature, except for the equity classified warrants included in the Initial Public Offering (see Note 9).

Warrants

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in ASC 480 and ASC Topic 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own ordinary shares, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent period end date while the warrants are outstanding.

For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded as liabilities at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss in the condensed statement of operations.

The warrants are not precluded from equity classification, and are accounted for as such on the date of issuance.

Recently Adopted Accounting Standards

In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). The amendments in this ASU require disclosures, on an annual and interim basis, of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”), as well as the aggregate amount of other segment items included in the reported measure of segment profit or loss.

The ASU requires that a public entity disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. Public entities will be required to provide all annual disclosures currently required by ASC Topic 280, Segment Reporting (“ASC 280”) in interim periods, and entities with a single reportable segment are required to provide all the disclosures required by the amendments in this ASU and existing segment disclosures in ASC 280. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted ASU 2023-07 on September 5, 2025, the date of inception.

No other recently issued accounting pronouncements are expected to have a material impact to the Company.

NOTE 3. INITIAL PUBLIC OFFERING

The registration statement for the Company’s Initial Public Offering was declared effective on January 13, 2026. On January 15, 2026, the Company consummated the Initial Public Offering of 28,750,000 Units, including 3,750,000 Units issued pursuant to the exercise of the Underwriters’ over-allotment option in full, generating gross proceeds of $287,500,000. Each Unit consisted of one Class A ordinary share and one-sixth of one redeemable warrant (“Public Warrant”). Each whole Public Warrant entitles the holder to purchase one Class A ordinary share at an exercise price of $11.50 per whole share, subject to adjustment (see Note 8).

NOTE 4. PRIVATE PLACEMENT

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 200,000 Private Placement Units, including 33,333 warrants, at a price of $10.00 per unit generating gross proceeds of $2,000,000 by and between the Company and the Sponsor. The proceeds from the sale of the Private Placement Units were added to the net proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the ~~Combination~~Completion Period, the proceeds from the sale of the Private Placement Units held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants will expire worthless.

NOTE 5. SEGMENT INFORMATION

ASC 280 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 that engage in business activities from which it may recognize revenues and incur expenses, and for which separate financial information is available that is regularly evaluated by the Company’s Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources and assess performance.

The Company’s CODM has been identified as the Chief Financial Officer, who reviews the operating results for the Company as a whole to make decisions about allocating resources and assessing financial performance. Management has determined that the Company only has one reportable segment.

The CODM assesses performance for the single segment and decides how to allocate resources based on net income or loss that also is reported on the condensed statement of operations as net income or loss. The measure of segment assets is reported on the condensed balance ~~sheet~~sheets as total assets, which were equal to $~~196~~290,~~107~~529,296 and $479,596 as of ~~September~~March 3031, 2026 and December 31, 2025, respectively. When evaluating the Company’s performance and making key decisions regarding resource allocation, the CODM reviews several key metrics included in net income or loss and total assets. The CODM reviews the current condition of its total assets available to assess if the Company has sufficient resources available to discharge its liabilities. The CODM is provided with details of cash and liquid resources available with the Company.

The CODM reviews formation, general and administrative expenses to manage and forecast cash to ensure enough capital is available to complete a ~~business~~Business ~~combination~~Combination or similar transaction within the ~~business~~Business ~~combination~~Combination period. The CODM also reviews formation, general and administrative expenses to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget.

NOTE 6. RELATED PARTY TRANSACTIONS

Founder Shares

On September 11, 2025 the Sponsor was issued 7,187,500 Class B ordinary shares (the “Founder Shares”) for an aggregate price of $25,000 paid to cover certain expenses on behalf of the Company. The Founder Shares included an aggregate of up to 937,500 Class B ordinary shares subject to forfeiture by the Sponsor to the extent that the Underwriters’ over-allotment option was not exercised in full or in part, so that the Sponsor would own, on an as-converted basis, 20% of the Company’s issued and outstanding shares after the Initial Public Offering (assuming the Sponsor does not purchase any Public Shares in the Initial Public Offering). On January 9, 2026, the Sponsor transferred 25,000 Founder Shares to each of the Company’s independent directors. On January 15, 2026, the Underwriters exercised their over-allotment option in full as part of the closing of the Initial Public Offering. As such, the 937,500 Founder Shares are no longer subject to forfeiture.

The Founder Shares are designated as Class B ordinary shares and, except as described below, are identical to the Class A ordinary shares included in the Units sold in the Initial Public Offering, and holders of Founder Shares have the same shareholder rights as Public Shareholders, except that (i) the Founder Shares are subject to certain transfer restrictions, as described in more detail below, (ii) the Founder Shares are entitled to registration rights, (iii) the Company’s Sponsor, officers and directors have entered into a letter agreement with the Company, pursuant to which they have agreed to (A) waive their redemption rights with respect to their Founder Shares and Public Shares in connection with the completion of the Company’s initial Business Combination, (B) waive their redemption rights with respect to their Founder Shares and Public Shares in connection with a shareholder vote to approve an amendment to the Company’s Amended and Restated Memorandum and Articles of Association (1) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial Business Combination or to redeem 100% of the Company’s Public Shares if the Company has not consummated an initial Business Combination within the Completion Period, (2) with respect to any other material provisions relating to shareholders’ rights or pre-initial Business Combination activity, (3) waive their rights to liquidating distributions from the Trust Account with respect to their Founder Shares if the Company fails to complete the Company’s initial Business Combination within the Completion Period, 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 the initial Business Combination within such time period and to liquidating distributions from assets outside the Trust Account and (4) vote any Founder Shares held by them and any Public Shares purchased during or after the Initial Public Offering (including in open market and privately negotiated transactions) in favor of the initial Business Combination (including any proposals recommended by the Company’s board of directors in connection with such Business Combination) (except with respect to any Public Shares 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), (iv) the Founder Shares are automatically convertible into Class A ordinary shares immediately prior to, concurrently with or immediately following the consummation of the Company’s initial Business Combination or at any time prior thereto at the option of the holder on a one-for-one basis, subject to adjustment as described herein and in the Memorandum and Articles of Association, and (v) prior to the closing of the Company’s initial Business Combination, only holders of Class B ordinary shares will be entitled to vote on the appointment and removal of directors or continuing in a jurisdiction outside the Cayman Islands (including any special resolution required to amend the constitutional documents or to adopt new constitutional documents, in each case, as a result of approving a transfer by way of continuation in a jurisdiction outside the Cayman Islands).

The Founder Shares will automatically convert into Class A ordinary shares immediately prior to, concurrently with or immediately following the consummation of the initial Business Combination or at any time prior thereto at the option of the holder on a one-for-one basis, subject to adjustment for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like, and subject to further adjustment as provided herein. In the case that additional Class A ordinary shares, or any other equity-linked securities, are issued or deemed issued in excess of the amounts sold in the Initial Public Offering and related to or in connection with the closing of the initial Business Combination, the ratio at which Class B ordinary shares convert into Class A ordinary shares will be adjusted (unless the holders of a majority of the outstanding Class B ordinary shares agree to waive such 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 (i) the total number of all Class A ordinary shares outstanding upon the completion of the Initial Public Offering (including any Class A ordinary shares issued pursuant to the Underwriters’ over-allotment option and excluding the Class A ordinary shares underlying the Private Placement Warrants issued to the Sponsor and the Underwriters), plus (ii) all Class A ordinary shares and equity-linked securities issued or deemed issued in connection with the Company’s initial Business Combination (excluding any shares or equity-linked securities issued, or to be issued, to any seller in the initial Business Combination and any private placement-equivalent warrants issued to the Company’s Sponsor or any of its affiliates or to the Company’s officers and directors upon conversion of working capital loans) minus (iii) any redemptions of Class A ordinary shares by Public Shareholders in connection with an initial Business Combination; provided that such conversion of Founder Shares will never occur on a less than one-for-one basis.

With certain limited exceptions, the Founder Shares are not transferable, assignable or saleable (except to the Company’s officers and directors and other persons or entities affiliated with the Company’s Sponsor, each of whom will be subject to the same transfer restrictions) until the earlier of (A) one year after the completion of the Company’s initial Business Combination or earlier if, subsequent to the Company’s initial Business Combination, the last sale price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Company’s initial Business Combination, and (B) the date following the completion of the Company’s initial Business Combination on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the Company’s shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property.

Promissory Note — Related Party

On September 11, 2025, the Sponsor agreed to loan the Company an aggregate of up to $300,000 to cover expenses related to the Initial Public Offering pursuant to a promissory note (the “Promissory Note”). This loan is non-interest bearing and payable on the earlier of December 31, 2025 or the date on which Company consummates an initial public offering of its securities. On January 6, 2026, the Promissory Note was amended to extend the maturity date to the earlier of January 31, 2026 or the Initial Public Offering date. On September 30, 2025, the Company had $0 outstanding under the Promissory Note.

Due to Related Party

Administrative Support Agreement

The Sponsor has agreed, commencing from the date of the Initial Public Offering through the earlier of the Company’s consummation of a Business Combination and its liquidation, to make available to the Company certain general and administrative services, including office space and administrative services, as the Company may require from time to time. The Company has agreed to pay to the Sponsor ~~up to~~ $10,000 per month for these services during the Completion Period.

Related Party Loans

In order to finance transaction costs in connection with the initial Business Combination, the Sponsor or an affiliate of the Sponsor or certain of 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, the Company will 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, including the repayment of loans from the Sponsor to pay for any amount deposited to pay for any extension of the time to complete the initial Business Combination, but no proceeds from the Trust Account would be used for such repayment. Up to $1,500,000 of such loans may be convertible into units, at a price of $10.00 per unit at the option of the lender, upon consummation of the initial Business Combination. Such units would be identical to the Private Placement Units. The terms of such loans by the Company’s officers and directors, if any, have not been determined and no written agreements exist with respect to such loans. There are no such outstanding related party loans as of ~~September~~March 3031, 2026 and December 31, 2025.

NOTE 7. COMMITMENTS AND CONTINGENCIES

Risks and Uncertainty

The United States and global markets are experiencing volatility and disruption following the geopolitical instability resulting from the ongoing Russia-Ukraine conflict and the Israel-Hamas conflict. In response to the ongoing Russia-Ukraine conflict, the North Atlantic Treaty Organization (“NATO”) deployed additional military forces to ~~eastern~~Eastern Europe. The United States, the United Kingdom, the European Union, and other countries have announced various sanctions and restrictive actions against Russia, Belarus and related individuals and entities, including the removal of certain financial institutions from the Society for Worldwide Interbank Financial Telecommunication payment system. Certain countries, including the United States, have also provided and may continue to provide military aid or other assistance to Ukraine and to Israel, increasing geopolitical tensions among a number of nations. The invasion of Ukraine by Russia, ~~and~~the conflict in the ~~Israel-Hamas~~Middle ~~conflict~~East and the resulting measures that have been taken, and could be taken in the future, by NATO, the United States, the United Kingdom, the European Union, Iran, Israel and its neighboring states and other countries have created global security concerns that could have a lasting impact on regional and global economies. Although the length and impact of the ongoing conflicts are highly unpredictable, they could lead to market disruptions, including significant volatility in commodity prices, credit and capital markets, as well as supply chain interruptions and increased cyberattacks against U.S. companies. Additionally, any resulting sanctions could adversely affect the global economy and financial markets and lead to instability and lack of liquidity in capital markets.

Any of the above mentioned factors, or any other negative impact on the global economy, capital markets or other geopolitical conditions resulting from the Russian invasion of Ukraine, the escalation of the ~~Israel-Hamas~~ conflict in the Middle East and subsequent sanctions or related actions, could adversely affect the Company’s search for an initial ~~business~~Business ~~combination~~Combination and any target business with which the Company may ultimately consummate an initial ~~business~~Business ~~combination~~Combination.

Registration Rights Agreement

The holders of the (i) Founder Shares, which were issued in a private placement prior to the closing of the Initial Public Offering, (ii) Private Placement Units and the Class A ordinary shares underlying such Private Placement Units and (iii) Private Placement Units that may be issued upon conversion of working capital loans will have registration rights to require the Company to register a sale of any of the Company’s securities held by them and any other securities of the Company acquired by them prior to the consummation of the Company’s initial Business Combination pursuant to a registration rights agreement signed on the effective date of the Initial Public Offering. Pursuant to the registration rights agreement and assuming $1,500,000 of working capital loans are converted into units, the Company will be obligated to register up to 7,595,833 Class A ordinary shares. The number of Class A ordinary shares includes (i) 7,187,500 Class A ordinary shares to be issued upon conversion of the Founder Shares, (ii) 200,000 Class A ordinary shares underlying the Private Placement Units and 33,333 Class A ordinary shares underlying the ~~private~~Private ~~placement~~Placement ~~warrants~~Warrants (iii) 150,000 Class A ordinary shares underlying the ~~private~~Private ~~placement~~Placement ~~units~~Units issued upon conversion of working capital loans and 25,000 Class A ordinary shares underlying the ~~private~~Private ~~placement~~Placement ~~units~~Units issued upon conversion of the working capital loans. On March 6, 2026, the holders of the Units were able to begin electing to separately trade the Class A ordinary shares and the warrants included in the Units. 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 “piggyback” registration rights with respect to registration statements filed subsequent to the Company’s completion of the Company’s initial ~~business~~Business ~~combination~~Combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

Pursuant to the underwriting agreement, the Sponsor and the executive officers and directors have agreed that, for a period of 180 days from the date of ~~this~~the ~~prospectus~~Initial Public Offering, will not, without the prior written consent of the representatives, offer, sell, contract to sell, pledge, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any units, warrants, ordinary shares or any other securities convertible into, or exercisable or exchangeable for, any units, ordinary shares, Founder Shares or warrants, subject to certain exceptions. The representatives in their discretion may release any of the securities subject to these lock-up agreements at any time without notice, other than in the case of the officers and directors, which shall be with notice. The Sponsor, officers and directors are also subject to separate transfer restrictions on their Founder Shares and Private Placement Warrants, as applicable, pursuant to the letter agreement described herein.

The Company granted the Underwriters a 45-day option to purchase up to 3,750,000 additional Units to cover over-allotments at the Initial Public Offering price, less the underwriting commissions. On January 15, 2026, simultaneously with the closing of the Initial Public Offering, the Underwriters elected to fully exercise the over-allotment option to purchase the additional 3,750,000 Units at a price of $10.00 per Unit.

Each whole Public Warrant entitles the registered holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing 30 days after the completion of the initial Business Combination. Pursuant to the warrant agreement, a warrant holder may exercise its Public Warrants only for a whole number of Class A ordinary shares. No fractional Public Warrants will be issued upon separation of the Units and only whole Public Warrants will trade. The Public Warrants will expire five years after the completion of the initial Business Combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

The Company has agreed that as soon as practicable, but in no event later than 20 business days after the closing of the initial Business Combination, the Company will use commercially reasonable efforts to file with the SEC a post-effective amendment to an existing registration statement or a new registration statement covering the registration, under the Securities Act, of the Class A ordinary shares issuable upon exercise of the warrants and thereafter will use the Company’s commercially reasonable efforts to cause the same to become effective within 60 business days following the initial Business Combination and to maintain a current prospectus relating to the Class A ordinary shares issuable upon exercise of the warrants, until the expiration of the warrants in accordance with the provisions of the warrant agreement. If a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants is not effective by the sixtieth (60) business day after the closing of the initial Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption.

Once the Public ~~warrant~~Warrants become exercisable, the Company may call the Public ~~warrants~~Warrants for redemption for cash:

●

in whole and not in part at a price of $0.01 per warrant;

●

upon a minimum of 30 days’ prior written notice of redemption; and

● if, and only if, the closing price of the Class A ordinary shares equals or exceeds $18.00 per share (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant as described below) for any 20 trading days within a 30-trading day period commencing at least 30 days after completion of the Company’s initial ~~business~~Business ~~combination~~Combination and ending three business days before the Company sends the notice of redemption to the warrant holders.

If and when the Public Warrants become redeemable by the Company for cash, the Company may exercise the redemption right even if the Company is unable to register or qualify the underlying securities for sale under all applicable state securities laws.

In addition, if (x) the Company issues additional Class A ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of the initial Business Combination at an issue price or effective issue price of less than $9.20 per Class A ordinary shares (with such issue price or effective issue price to be determined in good faith by the Company’s board of directors and, in the case of any such issuance to the initial shareholders or their affiliates, without taking into account any Founder Shares held by the initial shareholders or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the consummation of the initial Business Combination (net of redemptions), and the volume weighted average trading price of the Class A ordinary shares during the 20 trading day period starting on the trading day after the day on which the Company consummates the initial Business Combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $18.00 per -share redemption trigger price will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price.

The Private Placement Warrants (including the Class A ordinary shares issuable upon exercise of the Private Placement Warrants) will not be transferable, assignable or salable until 30 days after the completion of the initial Business Combination. The Private Placement Warrants have terms and provisions that are identical to those of the Public Warrants sold as part of the Units in the Initial Public Offering except that they are subject to certain transfer restrictions and not redeemable.

The Company ~~will~~accounts ~~account~~ for the 4,824,999 warrants issued in connection with the Initial Public Offering (including 4,791,666 Public Warrants and 33,333 Private Placement Warrants) in accordance with the guidance contained in ASC 815-40.

In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.

At the date of the Initial Public Offering, the fair value of the Public Warrants was $1,725,000, or $0.36 per Public Warrant. The fair value of Public Warrants was determined using Monte Carlo Simulation Model. The Public Warrants have been classified within shareholders’ deficit and will not require remeasurement after issuance. The following table presents the quantitative information regarding market assumptions used in the level 3 valuation of the Public Warrants:

Except as expressly required by applicable securities law, the Company disclaims any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise.

Overview

We are a blank check company or special purpose acquisition company incorporated under the laws of the Cayman Islands on September 5, 2025 formed for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or other similar ~~Business~~business ~~Combination~~combination with one or more businesses (the “Business Combination”). We intend to effectuate our Business Combination using cash derived from the proceeds of the Initial Public Offering and the sale of the Private Placement Units (defined below), our shares, debt or a combination of cash, shares and debt.

We expect to continue to incur significant costs in the pursuit of completing our ~~acquisition~~Business ~~plans~~Combination. We cannot assure you that our plans to complete a Business Combination will be successful.

Results of Operations

We have neither engaged in any operations nor generated any operating revenues to date. Our only activities from September 5, 2025 (inception) through ~~September 30~~March 31, ~~2025~~2026 were organizational activities and those necessary to prepare for the Initial Public Offering, described below. We do not expect to generate any operating revenues until after the completion of our initial Business Combination, at the earliest. We expect to generate non-operating income in the form of interest income on marketable securities held after the Initial Public Offering. We expect that we will incur increased expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses in connection with searching for, and completing, a Business Combination.

For the ~~period~~three ~~from~~months ~~September~~ended 5,March ~~2025 (inception) through September 30~~31, ~~2025~~2026, we had a net ~~loss~~income of $481,~~286~~688,089, which consisted of earnings on marketable securities held in a trust account maintained by Continental Stock Transfer & Trust Company, acting as trustee (the “Trust Account”), and interest income as offset by formation, general, and administrative ~~costs~~expenses.

Liquidity and Capital Resources

Until the consummation of the Initial Public Offering, our only source of liquidity was an initial purchase of Class B ordinary shares, par value $0.0001 per share, by the Sponsor and payments made on our behalf by our Sponsor.

~~Subsequent~~On ~~to the quarterly period covered by this Quarterly Report on Form 10-Q, on~~ January 15, 2026, we consummated the Initial Public Offering of 28,750,000 Units, ~~which includes~~ (the ~~full~~“Units” ~~exercise~~and, bywith respect to the ~~underwriters~~Class ofA ~~their~~ordinary ~~over-allotment~~shares ~~option~~included in the ~~amount of 3,750,000~~ Units, ~~at $10.00 per Unit~~sold, ~~generating~~ ~~gross~~the ~~proceeds~~“Public ~~of $287~~Shares”),~~500,000.~~ ~~Simultaneously~~which ~~with~~includes the ~~closing~~full ofexercise by the ~~Initial~~underwriters ~~Public~~of ~~Offering,~~their weover-allotment ~~consummated~~option in the ~~sale~~amount of ~~200~~ 3,750,000 ~~Private~~ Units, at ~~a price of~~ $10.00 per ~~Private~~ Unit, ~~in a private placement to our Sponsor,~~ generating gross proceeds of $2287,~~000~~500,000.

~~Following~~Simultaneously with the ~~Initial~~closing of the Initial Public Offering, ~~including~~ the ~~full~~Company ~~exercise of~~consummated the ~~underwriters’~~sale ~~over-allotment~~of ~~option~~200,000 ~~and~~units (the ~~sale of the~~ “Private Placement Units,”) aby ~~total~~and ofbetween ~~$287,500,000~~the ~~was~~Company and ~~placed~~OneIM inSponsor LLC (the ~~Trust~~“Sponsor”) ~~Account.

~~For~~Following the ~~period~~Initial ~~from~~Public ~~September 5~~Offering, ~~2025 (inception)~~including ~~through~~the ~~September~~full ~~30,~~exercise ~~2025~~of the underwriters’ over-allotment option, ~~net~~and ~~cash~~the ~~used~~sale inof ~~operating~~the ~~activities~~Private ~~was~~Placement ~~$0.~~Units, ~~Net~~a ~~loss~~total of $48287,~~286~~ 500,000 was ~~affected~~placed byin ~~payment~~the ofTrust ~~formation,~~Account. ~~general, and~~We ~~administrative~~incurred total transaction costs ~~through~~of a$16,687,698, ~~related~~consisting ~~party~~of $275,000 of cash underwriting fees, $3715,~~548.~~812,500 ~~Changes~~of indeferred ~~accrued~~underwriting ~~expenses~~fees ~~provided~~and $10600,~~738~~198 of ~~cash~~other ~~from~~offering ~~operating activities~~costs.

For the three months ended March 31, 2026, net cash used in operating activities was $582,422. Net income of $1,688,089 was adjusted for earnings on marketable securities held in Trust Account of $2,104,263. Changes in operating assets and liabilities used $166,248 of cash for operating activities primarily due to increases in prepaid insurance of $101,450, non-current prepaid insurance of $53,223, due to related party of $221,936, offset by increases in accounts payable of $29,763 and accrued expenses $180,598.

For the three months ended March 31, 2026, cash used in investing activities was $287,500,000, which was cash deposited in Trust Account of $287,500,000.

For the three months ended March 31, 2026, net cash provided by financing activities was 288,852,782, which was due to proceeds from sale of Units net of underwriting fees and reimbursement paid of $287,225,000, proceeds from sale of Private Placement Units of $1,988,200, proceeds from sale of Private Placement Warrants of $11,800, partially offset by payment of offering costs of $372,218.

We intend to use substantially all of the funds held in the Trust Account, including any amounts representing interest earned on the Trust Account (less income taxes payable), to complete our Business Combination. To the extent that our share capital or debt is used, in whole or in part, as consideration to complete our Business Combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue our growth strategies.

We intend to use the funds held outside the Trust Account primarily to identify and evaluate prospective target businesses, perform business due diligence on prospective target businesses, travel to and from the offices, plants or similar locations of prospective target businesses or their representatives or owners, review corporate documents and material agreements of prospective target businesses, select the target business to acquire and structure, negotiate and complete a Business Combination.

In order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, the Sponsor, or certain of our officers and directors or their affiliates may, but are not obligated to, loan us funds as may be required (a “Working Capital Loan”). If we complete a Business Combination, we would repay such loaned amounts. In the event that a Business Combination does not close, we may use a portion of the working capital held outside the Trust Account to repay such loaned amounts but no proceeds from our Trust Account would be used for such repayment. Up to $1,500,000 of such Working Capital Loans may be convertible into units of the post -Business Combination entity at a price of $10.00 per unit at the option of the lender. The units would be identical to the Private Placement Units.

We do not believe we will need to raise additional funds in order to meet the expenditures required for operating our business. However, if our estimate of the costs of identifying a target business, undertaking in-depth due diligence and negotiating a 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 Business Combination. Moreover, we may need to obtain additional financing either to complete our Business Combination or because we become obligated to redeem a significant number of our Public Shares upon consummation of our Business Combination, in which case we may issue additional securities or incur debt in connection with such Business Combination.

Off-Balance Sheet Arrangements

We have no obligations, assets or liabilities, which would be considered off-balance sheet arrangements as of ~~September 30~~March 31, ~~2025~~2026. We do not participate in transactions that create ~~relationships~~ 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

We do not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities, other than an agreement with the Sponsor, commencing on January 13, 2026, the effective date of the registration statement for the Company’s Initial Public Offering, through the earlier of the Company’s consummation of a Business Combination or its liquidation, to make available to the Company certain general and administrative services, including office space and administrative services, as the Company may require from time to time. The Company agreed to pay the Sponsor up to $10,000 per month for these services during the 24-month (or 27-month) period to complete a Business Combination.

The underwriters had a 45-day option from the date of the Initial Public Offering to purchase up to an additional 3,750,000 Units to cover over-allotments, if any. On January 15, 2026, the underwriters elected to fully exercise their over-allotment option to purchase an additional 3,750,000 Units at a price of $10.00 per Unit.

The underwriters were entitled to a cash underwriting amount of $250,000 in the aggregate, and an expense reimbursement of $25,000, paid at the closing of the Initial Public Offering. Additionally, the underwriters were entitled to a deferred underwriting discount of $0.55 per Unit, or $15,812,500 in the aggregate, payable upon the consummation of an initial Business Combination.

Critical Accounting Estimates

The preparation of unaudited condensed financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the unaudited condensed financial statements, and income and expenses during the periods reported. 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 unaudited condensed 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 materially differ from those estimates. As of ~~September 30~~March 31, ~~2025~~2026, we did not have any critical accounting estimates to be be disclosed.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Not required for smaller reporting companies.

Item 4. Controls and Procedures

Disclosure controls and procedures are controls and other procedures 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 management, including our Chief Executive Officer and Chief Financial Officer (together, the “Certifying Officers”), or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our management, including our Certifying Officers, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on the foregoing, our Certifying Officers concluded that our disclosure controls and procedures were effective as of the end of the quarterly period ended ~~September~~March 3031, ~~2025~~2026.

We do not expect that our disclosure controls and procedures will prevent all errors and all instances of fraud. Disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Further, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and the benefits must be considered relative to their costs. Because of the inherent limitations in all disclosure controls and procedures, no evaluation of disclosure controls and procedures can provide absolute assurance that we have detected all our control deficiencies and instances of fraud, if any. The design of disclosure controls and procedures also is based partly on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the quarterly period ended ~~September~~March 3031, ~~2025~~2026 that has materially affected, or is reasonably ~~likely~~ likely to materially affect, our internal control over financial reporting.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

~~There~~On ~~were no sales of unregistered securities during the quarterly period covered by this Quarterly Report. However, subsequent to the quarterly period covered by this Quarterly Report, on~~ January 15, 2026, we consummated the Initial Public Offering of 28,750,000 Public Units at $10.00 per Public Unit, which includes the full exercise of the underwriters’ over-allotment option of 3,750,000 Public Units, generating gross proceeds of $287,500,000. The securities sold in the Initial Public Offering were registered under the Securities Act on registration statement on Form S-1 (File No. 333-292356). The SEC declared the registration statement effective on January 13, 2026.

Simultaneously with the closing of the Initial Public Offering, we consummated the sale of an aggregate of 200,000 Private Placement Units to the Sponsor in a private placement, at at a price of $10.00 per Private ~~Placement~~ Unit, or $2,000,000 in the aggregate. The Private Placement Units are identical to the units sold in the Initial ~~IPO~~Public Offering, except as otherwise disclosed in our ~~IPO~~Initial Public Offering Registration Statement. No underwriting discounts or commissions were paid with respect to such sale.

Of the gross proceeds received from the Initial Public Offering and the net proceeds of the sale of the Private Placement Units, an aggregate of $287,500,000 was placed in the Trust Account.

We paid a total transaction costs of $880,000, consisting of $250,000 of cash underwriting fees, and $630,000 of other offering costs.

For a description of the use of the proceeds generated in our Initial Public Offering, see Part I, Item 2 of this Quarterly Report.
