NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS
Keystone Acquisition Corp. (the “Company”) is a blank check company incorporated in the Cayman Islands on
As of June 30, 2026, the Company had not commenced any operations. All activity for the period from November 28, 2025 (inception) through June 30, 2026 relates to the Company’s formation, initial public offering (“Initial Public Offering”), which is described below, and subsequent to the Initial Public Offering, identifying a target company for a Business Combination. 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 from the proceeds derived from the Initial Public Offering. 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 June 2, 2026. On June 4, 2026, the Company consummated the Initial Public Offering of
Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of

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 Warrants, 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

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 anticipated to be $
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 has agreed to vote its 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 don’t vote at all.
Notwithstanding 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
The Sponsor has agreed to waive redemption rights with respect to any Founder Shares (as defined in Note 6) held and any Public Shares they may acquire during or after the Initial Public Offering in connection with the completion of 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.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation
The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X of the SEC. Certain information or footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying unaudited condensed financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented.
The accompanying unaudited condensed financial statements should be read in conjunction with the Company’s prospectus for its Initial Public Offering as filed with the SEC on June 3, 2026, as well as the Company’s Current Report on Form 8-K, as filed with the SEC on June 10, 2026. The interim results for the three and six months ended June 30, 2026 are not necessarily indicative of the results to be expected for the year ending December 31, 2026 or for any future periods.
Liquidity, Capital Resources and Going Concern
The Company’s liquidity needs up to June 4, 2026 had been satisfied through the loan under an unsecured promissory note from the Sponsor of up to $
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 $

Based on the foregoing, management does not believe that the Company will have sufficient working capital and borrowing capacity to meet its needs through the earlier of the consummation of a Business Combination or one year from this filing. Over this time period, the Company will be using these funds to pay existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination.
In connection with the Company’s assessment of going concern considerations in accordance with FASB ASC 205-40, “Presentation of Financial Statements – Going Concern” (“ASC 205-40”), management has determined that the Company’s projected future liquidity position raises substantial doubt about the Company’s ability to continue as a going concern. The Company intends to complete its 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 March 4, 2028. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after March 4, 2028. The Company’s financial statements do not include any adjustment that might be necessary if the Company is unable to continue as a going concern.
Emerging Growth Company Status
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 auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.
Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such 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 the financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities.
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 from those estimates.
Cash and Cash Equivalents
The Company considers all short-term investments held outside of the Trust with an original maturity of three months or less when purchased to be cash equivalents. The Company had cash of $

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 Deposit Insurance Corporation coverage limit of $
Offering Costs
The Company complies with the requirements of FASB ASC 340-10-S99-1 and SEC Staff Accounting Bulletin Topic 5A, Expenses of Offering. Offering costs consist principally of professional and registration fees that are related to the Initial Public Offering. FASB ASC 470-20, Debt with Conversion and Other Options, addresses the allocation of proceeds from the issuance of convertible debt into its equity and debt components. The Company applies this guidance to allocate Initial Public Offering proceeds from the Public Units between Class A ordinary shares and warrants, using the residual method by allocating Initial Public Offering proceeds first to assigned value of the warrants and then to the Class A ordinary shares. Offering costs allocated to the Public Shares were charged to temporary equity and offering costs allocated to the Public and Private Placement Warrants were charged to shareholders’ deficit as Public and Private Placement Warrants, after management’s evaluation, were accounted for under equity treatment.
Income Taxes
The Company accounts for income taxes under FASB ASC 740, Income Taxes (“ASC 740”). FASB 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 carryforwards. FASB 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.
FASB 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 statements 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. FASB 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 unrecognized tax benefits and amounts accrued for interest and penalties as of June 30, 2026 and December 31, 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 are no taxes in the Cayman Islands, and accordingly, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company’s financial statements.

Class A Ordinary Shares Subject to Possible Redemption
The Public Shares issued as part of 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 FASB ASC Topic 480-10-S99, the Company classifies Public Shares subject to possible redemption outside of permanent equity as the redemption provisions are not solely within the control of the Company. The Company recognizes changes in redemption value immediately as they occur and will adjust the carrying value of redeemable shares to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption value. The change in the carrying value of redeemable shares will result in charges against additional paid-in capital (to the extent available) and accumulated deficit. Accordingly, as of June 30, 2026, Public Shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders’ deficit section of the Company’s balance sheet. As of December 31, 2025, there were no shares subject to redemption.

Net Income per Ordinary Share
The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” Income and losses are shared pro rata to the shares. Net income per Ordinary Share is computed by dividing net income by the weighted average number of Ordinary Shares outstanding for the period. Accretion associated with the redeemable Ordinary Shares is excluded from net income per Ordinary Share as the redemption value approximates fair value.
The calculation of diluted income per Ordinary Share does not consider the effect of the Warrants issued in connection with the (i) Initial Public Offering, (ii) the exercise of the over-allotment option and (iii) Private Placement, since the average price of the Ordinary Shares for the three and six months ended June 30, 2026, was less than the exercise price and therefore, the inclusion of such Warrants under the Treasury stock method would be anti-dilutive and the exercise is contingent upon the occurrence of future events.
The following tables reflect the calculation of basic and diluted net income per Ordinary Share:

Fair Value of Financial Instruments
The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC Topic 820, Fair Value Measurement, approximates the carrying amounts represented in the accompanying balance sheets, primarily due to their short-term nature (Note 9).
Share-Based Compensation
The Company accounts for share awards in accordance with FASB ASC 718, Compensation—Stock Compensation, which requires that all equity awards be accounted for at their “fair value.” Fair value is measured on the grant date and is equal to the underlying value of the share. Costs equal to these fair values are recognized ratably over the requisite service period based on the number of awards that are expected to vest, in the period of grant for awards that vest immediately and have no future service condition, or in the period the awards vest immediately after meeting a performance condition becomes probable (i.e., the occurrence of a Business Combination). For awards that vest over time, cumulative adjustments in later periods are recorded to the extent actual forfeitures differ from the Company’s initial estimates; previously recognized compensation cost is reversed if the service or performance conditions are not satisfied and the award is forfeited.
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 FASB ASC 480 and FASB ASC 815. The assessment considers whether the warrants are freestanding financial instruments pursuant to FASB ASC 480, meet the definition of a liability pursuant to FASB ASC 480, and whether the warrants meet all of the requirements for equity classification under FASB 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 quarterly 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 on the statement of operations.
The warrants are not precluded from equity classification and were accounted for as such on the date of issuance.
Referral Fee Income
Referral fee income is recognized when earned in accordance with the terms of the underlying agreement and is presented as part of the Other Income in the statements of operations. Such income is derived from the referral arrangements.
Recent Accounting Standards
Management does not believe that any recently issued, but not effective, accounting standards, if currently adopted, would have a material effect on the Company’s financial statements.

FASB 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 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”), or group, in deciding how to allocate resources and assess performance.
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 statement of operations as net income or loss. The measure of segment assets is reported on the balance sheets as total assets.

The CODM reviews general and administrative expenses to manage and forecast cash to ensure enough capital is available to complete a business combination or similar transaction within the business combination period. The CODM also reviews formation, general and administrative costs to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget. Formation, general and administrative costs, as reported on the statement of operations, are the significant segment information provided to the CODM on a regular basis. All other segment items included in net income or loss are reported on the statement of operations and described within their respective disclosures.
The CODM reviews the position of total assets 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. Additionally, the CODM regularly reviews the status of deferred costs incurred to assess if these are in line with the planned use of proceeds raised from the public offering.

The transfer of the Founder Shares to the holders of such interests is in the scope of FASB ASC 718.

NOTE 9. FAIR VALUE MEASUREMENTS
Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include:
| ● | Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets; |
| ● | Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and |
| ● | Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. 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. |
The following table presents information about the Company’s assets that are measured at fair value as of June 30, 2026 and December 31, 2025 and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value:

Special Note Regarding Forward-Looking Statements
This Quarterly Report includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Exchange Act that are not historical facts and involve risks and uncertainties that could cause actual results to differ materially from those expected and projected. All statements, other than statements of historical fact included in this Form 10-Q including, without limitation, statements in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” the Company’s financial position, business strategy and the plans and objectives of management for future operations, are forward-looking statements. Words such as “expect,” “believe,” “anticipate,” “intend,” “estimate,” “seek” and variations and similar words and expressions are intended to identify such forward-looking statements. Such forward-looking statements relate to future events or future performance, but reflect management’s current beliefs, based on information currently available. A number of factors could cause actual events, performance or results to differ materially from the events, performance and results discussed in the forward-looking statements. For information identifying important factors that could cause actual results to differ materially from those anticipated in the forward-looking statements, please refer to the Risk Factors section of the Company’s final prospectus for its Initial Public Offering filed with the U.S. Securities and Exchange Commission (the “SEC”). The Company’s securities filings can be accessed on the EDGAR section of the SEC’s website at www.sec.gov. 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 incorporated in the Cayman Islands on November 28, 2025 formed for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (a “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 Warrants, our shares, debt or a combination of cash, shares and debt.
We expect to continue to incur significant costs in the pursuit of our acquisition plans. 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 revenues to date. Our only activities from November 28, 2025 (inception) through June 30, 2026 were organizational activities, those necessary to prepare for the Initial Public Offering, described below, and identifying a target company for a Business Combination. We do not expect to generate any operating revenues until after the completion of our Business Combination. We generate non-operating income in the form of interest income on investments held in the Trust Account. We incur expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses.
20
For the three months ended June 30, 2026, we had a net income of $74,031, which consists of interest earned on investments held in the Trust Account of $754,831 and referral fee income of $12,500, offset by compensation expense of $245,099 and operating costs of $448,201.
For the six months ended June 30, 2026, we had a net income of $36,791, which consists of interest earned on investments held in the Trust Account of $754,831 and referral fee income of $12,500, offset by compensation expense of $245,099 and operating costs of $485,441.
Liquidity, Capital Resources and Going Concern
On June 4, 2026, we consummated the Initial Public Offering of 28,750,000 Units at $10.00 per Unit, generating gross proceeds of $287,500,000. Simultaneously with the closing of the Initial Public Offering, we consummated the sale of 8,468,750 Private Placement Warrants at a price of $1.00 per Private Placement Warrant, in a private placement to the Sponsor, and Cohen and Clear Street LLC, the representatives of the underwriters, generating gross proceeds of $8,468,750.
Following the closing of the Initial Public Offering on June 4, 2026, an amount of $288,218,750 ($10.025 per Unit) from the net proceeds of the sale of the Units, and a portion of the proceeds of the sale of the Private Placement Warrants, were placed in a trust account (“Trust Account”), located in the United States with Efficiency INC. acting as trustee and invested only in U.S. government treasury obligations 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, 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. We incurred $17,871,474, consisting of $5,750,000 of cash underwriting fees, $11,500,000 of deferred underwriting fees, and $621,474 of other offering costs.
For the six months ended June 30, 2026, cash used in operating activities was $274,474. Net income of $36,791 was affected by interest earned on investments held in the Trust Account of $754,831, compensation expense of $245,099 payment of operation costs through advances from related party of $5,877 and payment of operation costs through promissory note of $58,218. Changes in operating assets and liabilities provided $134,372 of cash for operating activities.
As of June 30, 2026, we had investments held in the Trust Account of $288,973,581 (including $754,831 of interest income) consisting of money market funds. We may withdraw interest from the Trust Account to pay taxes, if any. 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.
As of June 30, 2026, we had cash of $1,066,548. We intend to use the funds held outside the Trust Account primarily to identify and evaluate 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, 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. 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 loans may be convertible into warrants, at a price of $1.00 per warrant at the option of the lender, upon consummation of the initial Business Combination. The warrants would be identical to the Private Placement Warrants.
21
In connection with the Company’s assessment of going concern considerations in accordance with FASB ASC 205-40, “Presentation of Financial Statements – Going Concern” (“ASC 205-40”), management has determined that the Company’s projected future liquidity position raises substantial doubt about the Company’s ability to continue as a going concern. The Company intends to complete its 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 March 4, 2028. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after March 4, 2028. The Company’s financial statements do not include any adjustment that might be necessary if the Company is unable to continue as a going concern.
Off-Balance Sheet Arrangements
We have no obligations, assets or liabilities, which would be considered off-balance sheet arrangements as of June 30, 2026. We do not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. We have not entered into any off-balance sheet financing arrangements, established any special purpose entities, guaranteed any debt or commitments of other entities, or purchased any non-financial assets.
Contractual Obligations
We do not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities, other than an agreement to pay $20,000 per month to the Sponsor for these services during the 21-month period to complete a Business Combination.
The underwriters are entitled to a deferred fee of $0.40 per share in the Trust Account that is not redeemed after giving effect to a Business Combination, or $11,500,000 in the aggregate assuming no shares are redeemed in connection with a Business Combination based on the number of Class A ordinary shares outstanding as of June 30, 2026. The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that we complete a Business Combination, subject to the terms of the underwriting 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 Warrants which were issued in a private placement simultaneously with the closing of the Initial Public Offering and the Class A ordinary shares underlying such Private Placement Warrants and (iii) Private Placement Warrants that may be issued upon conversion of working capital loans 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 on the effective date of the Initial Public Offering. 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 Combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements.
22
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 judgement. 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 June 30, 2026, we did not have any critical accounting estimates to be disclosed.
Recent Accounting Standards
Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on our condensed financial statements.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
Not required for smaller reporting companies.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer 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 principal executive officer and principal financial and accounting officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the fiscal quarter ended June 30, 2026, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on this evaluation, our principal executive officer and principal financial and accounting officer have concluded that as of the end of the period covered by this report, our disclosure controls and procedures were effective at a reasonable assurance level and, accordingly, provided reasonable assurance that the information required to be disclosed by us in reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.
Changes in Internal Control over Financial Reporting
There was no change in our internal control over financial reporting that occurred during the quarter ended June 30, 2026 covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION
Item 1. Legal Proceedings
We are not aware of any material pending legal proceedings, including litigation, investigations, and other claims, to which we are a party.
Item 1A. Risk Factors
Factors that could cause our actual results to differ materially from those in this report include the risk factors described in our final prospectus for the Initial Public Offering filed with the SEC. As of the date of this Report, there have been no material changes to the risk factors disclosed in our final prospectus for the Initial Public Offering filed with the SEC.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.
On June 4, 2026, we consummated the Initial Public Offering of 28,750,000 Units at $10.00 per Unit, generating gross proceeds of $287,500,000. Cohen acted as Lead Book-Running Manager of the Initial Public Offering. The securities in the offering were registered under the Securities Act on a registration statement on Form S-1 (No. 333-295539). The Securities and Exchange Commission declared the registration statement effective on June 2, 2026.
Simultaneously with the closing of the Initial Public Offering, we consummated the sale of 8,468,750 Private Placement Warrants at a price of $1.00 per Private Placement Warrant, in a private placement to the Sponsor, and Cohen and Clear Street LLC, the representatives of the underwriters, generating gross proceeds of $8,468,750. Each whole Private Placement Warrant is exercisable to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment, terms and limitations as described herein. The issuance was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act.
On June 4, 2026, the underwriters exercised their over-allotment option in full, resulting in the sale of an additional 3,750,000 units. A total of $288,218,750 was deposited into the Trust Account.
Of the gross proceeds received from the Initial Public Offering, the exercise of the over-allotment option and the Private Placement Warrant, an aggregate of $288,218,750 was placed in the Trust Account.
We paid a total of $17,871,474, consisting of $5,750,000 of cash underwriting fees, $11,500,000 of deferred underwriting fees, and $621,474 of other costs and expenses relating to the Initial Public Offering.
