Significant Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

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

Principles of Consolidation

Principles of Consolidation

Plum IV Merger Sub Inc. (“Merger Sub”) was incorporated in Delaware on March 4, 2026, and was formed for the purpose of merging with the Company prior to the transactions contemplated in the Business Combination Agreement to facilitate the consummation of the proposed Business Combination. The Company has one wholly owned subsidiary, Merger Sub.

The accompanying consolidated financial statements include the accounts of the Company and Merger Sub. All significant intercompany balances and transactions have been eliminated in consolidation.

Liquidity and Going Concern

Liquidity and Going Concern

As of March 31, 2026, the Company had $93,512 in cash and cash equivalents and working capital deficit of $318,003. Further, the Company has incurred and expects to continue to incur significant costs in pursuit of its acquisition plans. There is no assurance that the Company’s plans to raise capital will be successful. Further, the Company has until July 16, 2026 to complete its initial business combination or it will liquidate absent any shareholder approved extensions. In connection with the Company’s assessment of going concern considerations in accordance with Accounting Standards Codification (“ASC”) Topic 205-40, “Presentation of Financial Statements - Going Concern,” as of March 31, 2026, management has determined that mandatory liquidation, should a Business Combination not occur, and potential subsequent dissolution and the liquidity condition issue raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date the unaudited condensed consolidated financial statements are issued.

No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after the Combination Period. The Company cannot assure that its plans to raise capital or to consummate an Initial Business Combination will be successful.

Emerging Growth Company

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 auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, 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.

Use of Estimates

Use of Estimates

The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires 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 unaudited condensed consolidated financial statements and the reported amounts of expenses during the reporting periods.

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 consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

Cash and Cash Equivalents

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 $30,000 in cash as of March 31, 2026 and December 31, 2025. The Company had $63,512 and $266,249 in cash equivalents as of March 31, 2026 and December 31, 2025, respectively.

Investments Held in Trust Account

Investments Held in Trust Account

As of March 31, 2026 and December 31, 2025, the investments held in the Trust Account, amounting to $182,735,189 and $181,285,220, were held in U.S. government treasury bills, respectively.

Offering Costs

Offering Costs

The Company complies with the requirements of the Financial Accounting Standards Board (“FASB”) ASC 340-10-S99 and SEC Staff Accounting Bulletin Topic 5A, “Expenses of Offering.” Offering costs consist principally of professional and registration fees that are directly 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 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 Public Warrants (as defined below) and Private Placement Units and Restricted Shares were charged to shareholders’ deficit as the Public and Private Placement Warrants (as defined below), after management’s evaluation, were accounted for under equity treatment.

Income Taxes

Income Taxes

The Company accounts for income taxes under ASC 740, “Income Taxes” (“ASC 740”). ASC 740 requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the unaudited condensed consolidated financial statements and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carry forwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized.

ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s unaudited condensed consolidated financial statements and prescribes a recognition threshold and measurement process for unaudited condensed consolidated 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. 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 March 31, 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. The Company has been subject to income tax examinations by major taxing authorities since inception.

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’s tax provision was zero for the periods presented.

Net Income per Ordinary Share

Net Income per Ordinary Share

Net income per ordinary share is computed by dividing net income by the weighted average number of ordinary shares issued and outstanding during the period, excluding ordinary shares subject to forfeiture. Weighted average shares were reduced for the effect of an aggregate of 750,000 Class B ordinary shares that were subject to forfeiture depending on the extent to which the underwriters’ over-allotment option is exercised (see Note 5). As of March 31, 2026 and March 31, 2025, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into ordinary shares and then share in the earnings of the Company. As a result, diluted income per ordinary share is the same as basic income per ordinary share for the period presented.

The following table reflects the calculation of basic and diluted net income per ordinary share (in dollars, except per share amounts):

	For the Three Months Ended March 31, 2026				For the Three Months Ended March 31, 2025
	Class A		Class B		Class A		Class B
Basic net income per share of common stock:
Numerator:
Allocation of net income	$	914,720	$	284,414	$	849,124	$	332,931
Denominator:
Weighted-average shares outstanding		18,492,875		5,750,000		14,342,697		5,623,596
Basic net income per ordinary share	$	0.05	$	0.05	$	0.06	$	0.06

	For the Three Months Ended March 31, 2026				For the Three Months Ended March 31, 2025
	Class A		Class B		Class A		Class B
Diluted net income per share of common stock:

Allocation of net income	$	914,720	$	284,414	$	843,782	$	338,273
Denominator:
Weighted-average shares outstanding		18,492,875		5,750,000		14,342,697		5,750,000
Diluted net income per ordinary share	$	0.05	$	0.05	$	0.06	$	0.06

Concentration of Credit Risk

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times may exceed the Federal Depository Insurance Corporation coverage 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.

Fair Value of Financial Instruments

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 consolidated balance sheets, primarily due to their short-term nature.

Warrant Instruments

Warrant Instruments

The Company will account for the Public and Private Placement Warrants issued in connection with the Initial Public Offering, on January 16, 2025 and the private placement in accordance with the guidance contained in FASB ASC Topic 815, “Derivatives and Hedging.” Accordingly, the Company evaluated and classified the warrant instruments under equity treatment at their assigned values.

The fair value of the Public Warrants was $603,750, or $0.07 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:

	January 16, 2025
Underlying stock price	$	9.98
Exercise price	$	11.50
Remaining term (years)		6.74
Annual volatility		2.9	%
Annual risk-free rate		4.39	%
Pre-adjusted value per share	$	1.43
Market adjustment		5.0	%

Class A Ordinary Shares Subject to Possible Redemption Classification

Class A Ordinary Shares Subject to Possible Redemption Classification

The public shares contain a redemption feature which allows for the redemption of such public shares in connection with the Company’s liquidation, or if there is a shareholder vote or tender offer in connection with the Company’s initial Business Combination. In accordance with ASC 480-10-S99, the Company classifies public shares subject to possible redemption outside of permanent deficit as the redemption provisions are not solely within the control of the Company. The Company recognizes changes in redemption value immediately as it occurs 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 amount 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 March 31, 2026 and December 31, 2025, Class A ordinary shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders’ deficit section of the Company’s condensed consolidated balance sheets. As of March 31, 2026 and December 31, 2025, the Class A ordinary shares subject to possible redemption reflected in the condensed consolidated balance sheets are reconciled in the following table:

Gross proceeds	$	172,500,000
Less:
Proceeds allocated to Public Warrants		(603,750	)
Public Shares issuance costs		(10,872,242	)
Plus:
Accretion of carrying value to redemption value		20,261,212
Class A ordinary shares subject to possible redemption, December 31, 2025		181,285,220
Plus:
Accretion of carrying value to redemption value		1,449,969
Class A ordinary shares subject to possible redemption, March 31, 2026	$	182,735,189

Share-Based Compensation

Share-Based Compensation

The Company records share-based compensation in accordance with FASB ASC Topic 718, “Compensation-Share Compensation” (“ASC 718”), guidance to account for its share-based compensation. It defines a fair value-based method of accounting for an employee share option or similar equity instrument. The Company recognizes all forms of share-based payments at their fair value on the grant date, which are based on the estimated number of awards that are ultimately expected to vest. Share-based payments are valued using a Black-Scholes option pricing model. Grants of share-based payment awards issued to non-employees for services rendered have been recorded at the fair value of the share-based payment, which is the more readily determinable value. The grants are amortized on a straight-line basis over the requisite service periods, which is generally the vesting period. If an award is granted, but vesting does not occur, any previously recognized compensation cost is reversed in the period related to the termination of service. Share-based compensation expenses are included in costs and operating expenses depending on the nature of the services provided in the unaudited condensed consolidated statements of operations.

Derivative financial instruments

Derivative Financial Instruments

The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, “Derivatives and Hedging.” For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the unaudited condensed consolidated statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the condensed consolidated balance sheets as current or non-current based on whether or not net cash settlement or conversion of the instrument could be required within 12 months of the condensed consolidated balance sheet date. The underwriters’ over-allotment option is deemed to be a freestanding financial instrument indexed on the contingently redeemable shares and would have been accounted for as a liability pursuant to ASC 480 if not fully exercised at the time of the Initial Public Offering. Because the over-allotment option was fully exercised at the time of the Initial Public Offering, no liability remained outstanding subsequent to the offering date.

Recently Issued Accounting Standards

Recently Issued Accounting Standards

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 unaudited condensed consolidated financial statements.
