Significant Accounting Policies [Abstract]

Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Stepping Stone Merger Sub, Inc. All intercompany transactions and balances, if any, have been eliminated in consolidation.

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”). As such, the Company is eligible to 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.

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 unaudited condensed consolidated 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.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had $356,941 and $991,532 in cash and no cash equivalents as of September 30, 2026 and December 31, 2025, respectively.

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 $250,000. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s financial condition, results of operations, and cash flows.

Income Taxes

The Company accounts for income taxes under FASB ASC 740, Income Taxes (“FASB 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. 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 the 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. FASB ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim period, disclosure and transition.

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, 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 unaudited condensed consolidated financial statements.

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 Topic 480, Distinguishing Liabilities from Equity (“FASB ASC 480”), and FASB ASC Topic 815, Derivatives and Hedging (“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 unaudited condensed consolidated statements of operations.

Accordingly, the Company evaluated and classified the warrant instruments under equity treatment at their assigned values. As of September 30, 2026 and December 31, 2025, there were 17,235,000 Public Warrants and 8,894,000 Private Placement Warrants outstanding.

Share-Based Payment Arrangements

The Company accounts for share awards in accordance with FASB ASC 718, Compensation—Stock Compensation (“FASB ASC 718”), 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.

Net Income (Loss) per Ordinary Share

Diluted net income (loss) per share attributable to ordinary shareholders adjusts the basic net income (loss) per share attributable to ordinary shareholders and the weighted-average ordinary shares outstanding for the potentially dilutive impact of outstanding warrants. However, because the warrants are anti-dilutive, diluted income (loss) per ordinary share is the same as basic income (loss) per ordinary share for the periods presented.

The calculation of diluted net income (loss) per ordinary share does not consider the effect of the warrants issued in connection with the Initial Public Offering and the private placement, which are exercisable to purchase an aggregate of 26,129,000 Class A ordinary shares (17,235,000 Public Warrants and 8,894,000 Private Placement Warrants), because their inclusion would be anti-dilutive. Accordingly, these warrants were excluded from the computation of diluted net income per ordinary share for the three and nine months ended September 30, 2026. No warrants were outstanding during the three months ended September 30, 2025 or the period from June 26, 2025 (inception) through September 30, 2025. As a result, diluted net income (loss) per ordinary share is the same as basic net income (loss) per ordinary share for both Class A and Class B ordinary shares for the periods presented.
