Summary of Significant Accounting Policies [Abstract]

Use of Estimates

The preparation of financial 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 and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Such estimates may be subject to change as more current information becomes available, and accordingly, the actual results could differ significantly from those estimates.

Cash and Cash Equivalents

Cash and Cash Equivalents

The Company considers all short-term investments (if any) with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents in its operating account or the Trust Account as of both December 31, 2025 and 2024.

Available-for-Sale Debt Securities

Available-for-Sale Debt Securities

The Company’s investments held in the Trust Account as of December 31, 2025 comprised of a direct investment in U.S. government treasury bills.

The Company accounts for its investment in debt securities in accordance with the guidance in ASC 320, Investments—Debt and Equity Securities. When the Company has the ability and positive intent to hold debt securities until maturity, such securities are classified as held-to-maturity and carried at amortized cost. None of the Company’s debt securities met the criteria for held-to-maturity classification as of December 31, 2025. As the Company does not have the ability or positive intent to hold its debt securities until maturity, the securities are classified as available-for-sale. Unrealized gains and losses from available-for-sale debt securities carried at fair value are reported as a separate component of Accumulated other comprehensive income in shareholders’ equity (deficit). Interest income recognized on the statements of operations reflects accretion of discount. Investments in debt securities are recorded on a trade-date basis.

Concentration of Credit Risk

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist of cash accounts in financial institutions which, at times, may exceed the Federal Deposit Insurance Corporation maximum coverage limit of $250,000, and investments in the U.S. government debt securities held in the Trust Account. For both the years ended December 31, 2025 and 2024, the Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

Under ASC 820, Fair Value Measurement (“ASC 820”), “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. The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC 820 approximates the carrying amounts presented in the balance sheets, primarily due to their short-term nature, with the exception of the available-for-sale debt securities.

Offering Costs Associated with the Initial Public Offering

Offering Costs Associated with the Initial Public Offering

Offering costs consisted of legal and other fees incurred in connection with the preparation for the Initial Public Offering. These costs amounted to approximately $8,600,000 and were charged against the carrying value of the Public Shares upon the completion of the Initial Public Offering. Deferred offering costs of approximately $300 incurred through the December 31, 2024 balance sheet date consisted of legal fees that were directly related to the Initial Public Offering.

Class A Ordinary Shares Subject to Possible Redemption

Class A Ordinary Shares Subject to Possible Redemption

The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in ASC 480. Class A ordinary shares subject to mandatory redemption (if any) are classified as liability instruments and measured at fair value. 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. At all other times, Class A ordinary shares are classified as shareholders’ equity. All of the Public Shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of December 31, 2025 and 2024, 45,000,000 and 0 Class A ordinary shares subject to possible redemption, respectively, are presented as temporary equity outside of the shareholders’ equity (deficit) section of the Company’s balance sheets. The Company recognizes any subsequent changes in redemption value immediately as they occur and adjusts the carrying value of redeemable Class A ordinary shares to 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 amount value of redeemable Class A ordinary shares. This method would view the end of the reporting period as if it were also the redemption date for the security. The change in the carrying value of redeemable Class A ordinary shares also resulted in charges against Additional paid-in capital and Accumulated deficit.

As of December 31, 2025 and 2024, the Class A ordinary shares subject to possible redemption, as presented in the accompanying balance sheets, are reconciled in the following table:

Net Income (Loss) Per Ordinary Share

Net Income (Loss) Per Ordinary Share

The Company complies with the accounting and disclosure requirements of ASC 260, Earnings Per Share. Net income (loss) per ordinary share is computed by dividing net income (loss) applicable to shareholders by the weighted average number of ordinary shares outstanding for the applicable periods. The Company applies the two-class method in calculating earnings per share and allocates net income (loss) pro rata to Class A ordinary shares subject to possible redemption, nonredeemable Class A ordinary shares and Class B ordinary shares. Accretion associated with the redeemable Class A ordinary shares is excluded from earnings per share as the redemption value is not in excess of fair value.

The following table reflects the calculation of basic and diluted net income (loss) per ordinary share:

	For the Year Ended December 31, 2025						For the Year Ended December 31, 2024

Income Taxes

Income Taxes

Income taxes are accounted for using the asset and liability method as prescribed under ASC 740, Income Taxes (“ASC 740”). Deferred tax assets and liabilities are recognized for the future tax consequences attributable to basis differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis.

ASC 740 prescribes a recognition threshold that a tax position is required to meet before being recognized in the financial statements. The Company provides for uncertain tax positions, based upon management’s assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. Management is required to determine whether a tax position is more likely than not to be sustained upon examination by tax authorities, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Because significant assumptions are used in determining whether a tax benefit is more likely than not to be sustained upon examination by tax authorities, actual results may differ from management’s estimates under different assumptions or conditions. The Company recognizes interest and penalties related to unrecognized tax benefits as provision for income taxes on the statements of operations.

No amounts were accrued for the payment of interest and penalties as of both December 31, 2025 and 2024. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. As of both December 31, 2025 and 2024, the Company has not recorded any amounts related to uncertain tax positions.

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. As such, the Company recorded no income tax provision for the periods presented.

Segment Reporting

Segment Reporting

The Company has one reportable segment. See Note 9—Segment Information for additional information.

Recently Adopted Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In November 2023, the FASB issued Accounting Standards Update (“ASU”) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The guidance was issued in response to requests from investors for companies to disclose more information about their financial performance at the segment level. The ASU does not change how a public entity identifies its operating segments, aggregates them or applies the quantitative thresholds to determine its reportable segments. The standard requires a public entity to disclose significant segment expenses and other segment items on an annual and interim basis, and to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that were previously required annually. Public entities with a single reportable segment are required to provide the new disclosures and all the disclosures previously required under ASC 280. The Company adopted the standard on the required effective date for the financial statements issued for the annual reporting periods beginning on January 1, 2024 and applies the guidance for the interim periods beginning on January 1, 2025. The adoption of the new guidance did not have an impact on the Company’s financial statements.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The standard improves the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The ASU also includes certain other amendments to improve the effectiveness of income tax disclosures. The Company adopted the standard on the required effective date for the Company’s financial statements issued for annual reporting periods beginning on January 1, 2025. The adoption of this guidance did not have a material impact on the footnotes to the Company’s financial statements and had no impact on the Company’s financial statements.

In March 2024, the FASB issued ASU No. 2024-02, Codification Improvements—Amendments to Remove References to the Concepts Statements. The Conceptual Framework establishes concepts that the FASB considers in developing standards. The ASU was issued to remove references to the Conceptual Framework in the Codification. The FASB noted that references to the Concepts Statements in the Codification could have implied that the Concepts Statements are authoritative. Also, some of the references removed were to Concepts Statements that are superseded. The Company adopted the standard on the required effective date beginning on January 1, 2025 using a prospective transition method for all new transactions recognized on or after the effective date. The adoption of this guidance did not have a material impact on the Company’s financial statements.

New Accounting Pronouncements

New Accounting Pronouncements

In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The standard improves financial reporting and responds to investor input that additional expense detail is fundamental to understanding the performance of an entity, assessing its prospects for future cash flows, and comparing its performance over time and with that of other entities. The new guidance requires public business entities to disclose in the notes to financial statements specified information about certain costs and expenses at each interim and annual reporting period. Specified expenses, gains or losses that are already disclosed under existing U.S. GAAP will be required by the ASU to be included in the disaggregated income statement expense line item disclosures, and any remaining amounts will need to be described qualitatively. The new guidance will become effective for the Company’s financial statements issued for annual reporting periods beginning on January 1, 2027 and interim reporting periods beginning on January 1, 2028, will require either prospective or retrospective presentation, and early adoption is permitted. Management is currently evaluating the impact of the new standard on the Company’s financial statements.

In May 2025, the FASB issued ASU No. 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity. The standard revises current guidance for determining the accounting acquirer for a transaction effected primarily by exchanging equity interests in which the legal acquiree is a variable interest entity (“VIE”) that meets the definition of a business. The amendments differ from current U.S. GAAP because, for certain transactions, they replace the requirement that the primary beneficiary of a VIE is always the acquirer with an assessment that requires an entity to consider the factors to determine which entity is the accounting acquirer. Under the amendments, acquisition transactions in which the legal acquiree is a VIE will, in more instances, result in the same accounting outcomes as economically similar transactions in which the legal acquiree is a voting interest entity. The ASU does not change the accounting for a transaction determined to be a reverse acquisition or a transaction in which the legal acquirer is not a business and is determined to be the accounting acquiree. The new guidance will become effective for interim and annual reporting periods beginning on January 1, 2027, will require a prospective transition method for business combinations that occur after the initial adoption date, and early adoption is permitted. Management is currently evaluating the impact of the new standard on the Company’s financial statements.

In December 2025, the FASB issued ASU No. 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. The guidance clarifies the current interim disclosure requirements and their applicability. The ASU is intended to address feedback from stakeholders that the current guidance is difficult to navigate. The amendments do not change the fundamental nature or expand or reduce the disclosure requirements of interim reporting. The ASU creates a comprehensive list of interim disclosures required under U.S. GAAP and incorporates a disclosure principle that requires disclosures at interim periods when an event or change that has a material effect on an entity has occurred since the previous year end. The new guidance will become effective for the Company beginning on January 1, 2028, can be adopted using either a prospective or retrospective method, and early adoption is permitted. Management is currently evaluating the impact of the new standard on the Company’s financial statements.

In December 2025, the FASB issued ASU No. 2025-12, Codification Improvements. The guidance clarifies, corrects errors in or makes other improvements to a variety of topics in the Codification that are intended to make it easier to understand and apply. The amendments apply to all reporting entities in the scope of the affected accounting guidance. The new guidance will become effective for the Company beginning on January 1, 2027, can be adopted using either a prospective or retrospective method, and early adoption is permitted. Management is currently evaluating the impact of the new standard on the Company’s financial statements.

SEC Rule on Climate-Related Disclosures

SEC Rule on Climate-Related Disclosures

In March 2024, the SEC adopted final rules relating to The Enhancement and Standardization of Climate-Related Disclosures for Investors, that would require registrants to provide climate-related disclosures in a note to their audited financial statements. The disclosures under the final rules would include certain effects of severe weather events and other natural conditions, including the aggregate amounts and where in the financial statements they are presented. If carbon offsets or renewable energy credits or certificates (“RECs”) are deemed a material component of the registrant’s plans to achieve its disclosed climate-related targets, registrants would be required to disclose information about the offsets and RECs. Registrants would also be required to disclose whether and how (1) exposures to risks and uncertainties associated with, or known impacts from, severe weather events and other natural conditions and (2) any disclosed climate-related targets or transition plans materially impacted the estimates and assumptions used in preparing the financial statements. Finally, registrants would be required to disclose additional contextual information about the above disclosures, including how each financial statement effect was derived and the accounting policy decisions made to calculate the effects, for the most recently completed fiscal year and, if previously disclosed or required to be disclosed, for the historical fiscal year for which audited financial statements are included in the filing. In April 2024, the SEC released an order staying the rules pending judicial review of all of the petitions challenging the rules and in March 2025, the SEC voted to end its defense of the rules. Absent these developments, the rules would have been effective for the Company upon its registration under the Exchange Act on August 20, 2025 and phased in starting in 2027. Management is continuing to monitor the developments pertaining to the rules and any resulting potential impacts on the Company’s financial statements.

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