Following the closing of the Initial Public Offering on December 19, 2025, an amount of $230,000,000 ($10.00 per Unit) from the net proceeds of the sale of the Units, and a portion of the net proceeds from the sale of the Private Placement Warrants, was held in a Trust Account (the “Trust Account”) and was initially 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; the holding of these assets in this form is intended to be temporary and for the sole purpose of facilitating the intended Business Combination. To mitigate the risk that the Company might be deemed to be an investment company for purposes of the Investment Company Act, which risk increases the longer that the Company holds investments in the Trust Account, the Company may, at any time (based on the management team’s ongoing assessment of all factors related to the Company’s potential status under the Investment Company Act), instruct the trustee to liquidate the investments held in the Trust Account and instead to hold the funds in the Trust Account in cash or in an interest bearing demand deposit account at a bank. Except with respect to (i) interest earned on the funds held in the Trust Account that may be released to the Company to pay its taxes, if any, and (ii) permitted withdrawals of up to $200,000 per year of interest income for working capital expenses as described herein, the proceeds from the Initial Public Offering and the sale of the Private Placement Warrants will not be released from the Trust Account until the earliest of (i) the completion of the Company’s initial Business Combination, (ii) the redemption of the Company’s public shares if the Company is unable to complete the initial Business Combination within 24 months from the closing of the Initial Public Offering (i.e., by December 19, 2027) or by such earlier liquidation date as the Company’s board of directors may approve (the “Completion Window”), subject to applicable law, or (iii) the redemption of the Company’s public shares properly submitted in connection with a shareholder vote to amend the Company’s amended and restated memorandum and articles of association to (A) modify the substance or timing of the Company’s obligation to allow redemption in connection with the 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 Window or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial Business Combination activity. The proceeds deposited in the Trust Account could become subject to the claims of the Company’s creditors, if any, which could have priority over the claims of the Company’s public shareholders.

The Company will provide its public shareholders with the opportunity to redeem all or a portion of their public shares upon the completion of the initial Business Combination either (i) in connection with a general meeting called to approve the initial Business Combination or (ii) without a shareholder vote by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a proposed initial 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 shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account calculated as of two business days prior to the consummation of the initial Business Combination, including interest earned on the funds held in the Trust Account (less permitted withdrawals), divided by the number of then outstanding public shares, subject to the limitations. The amount in the Trust Account is initially anticipated to be $10.00 per public share.

The ordinary shares subject to redemption were recorded at a redemption value and classified as temporary equity upon the completion of the Initial Public Offering, in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity.”

The Company will have only the duration of the Completion Window to complete the initial Business Combination. However, if the Company is unable to complete its initial Business Combination within the Completion Window, the Company will as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account (less permitted withdrawals and up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will constitute full and complete payment for the public shares and completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation or other distributions, if any), subject to the Company’s obligations under Cayman Islands law to provide for claims of creditors and subject to the other requirements of applicable law.

The Sponsor, officers and directors have entered into a letter agreement with the Company, pursuant to which they have agreed to (i) waive their redemption rights with respect to their founder shares and public shares in connection with the completion of the initial Business Combination; (ii) 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; (iii) waive their rights to liquidating distributions from the Trust Account with respect to their founder shares if the Company fails to complete the initial Business Combination within the Completion Window, 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 the Completion Window and to liquidating distributions from assets outside the Trust Account; and (iv) 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, aside from shares they may purchase in compliance with the requirements of Rule 14e-5 under the Exchange Act, which would not be voted in favor of approving the Business Combination) in favor of the initial Business Combination.

The Company’s 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 has 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 share due to reductions in the value of the trust assets, less permitted withdrawals, 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 Company’s 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”). However, the Company has not asked the Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and the Company believes that the Sponsor’s only assets are securities of the Company. Therefore, the Company cannot assure that the Sponsor would be able to satisfy those obligations.

Under the terms of the warrant agreement dated December 17, 2025, by and between the Company and Continental Stock Transfer & Trust Company, as warrant agent (the “Warrant Agreement”), the Company has agreed that, as soon as practicable, but in no event later than 20 business days after the closing of its initial Business Combination, it will use commercially reasonable efforts to file with the SEC a post-effective amendment to the registration statement for the Initial Public Offering 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 its commercially reasonable efforts to cause the same to become effective within 60 business days following the Company’s 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^th) 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. Notwithstanding the above, if the Class A ordinary shares are at the time of any exercise of a warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, the Company will not be required to file or maintain in effect a registration statement, and in the event the Company does not so elect, the Company will use its commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

If the holders exercise their Public Warrants on a cashless basis, they would pay the warrant exercise price by surrendering the warrants for that number of Class A ordinary shares equal to the quotient obtained by dividing (x) the product of the number of Class A ordinary shares underlying the warrants, multiplied by the excess of the “fair market value” of the Class A ordinary shares over the exercise price of the warrants by (y) the fair market value. The “fair market value” is the average reported closing price of the Class A ordinary shares for the 10 trading days ending on the third trading day prior to the date on which the notice of exercise is received by the warrant agent or on which the notice of redemption is sent to the holders of warrants, as applicable.

If the Price per Class A ordinary share equals or exceeds $18.00, the Company may redeem the outstanding warrants: (i) in whole and not in part; (ii) at a price of $0.01 per warrant; (iii) upon a minimum of 30 days’ prior written notice of redemption (the “30-day redemption period”); and (iv) 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) for any 20 trading days within a 30-trading day period commencing at least 30 days after completion of the Company’s initial Business Combination and ending three business days before the Company sends the notice of redemption to the warrant holders.

Additionally, if the number of outstanding Class A ordinary shares is increased by a share capitalization payable in Class A ordinary shares, or by a subdivision of ordinary shares or other similar event, then, on the effective date of such share capitalization, subdivision or similar event, the number of Class A ordinary shares issuable on exercise of each warrant will be increased in proportion to such increase in the outstanding ordinary shares. A rights offering made to all or substantially all holders of ordinary shares entitling holders to purchase Class A ordinary shares at a price less than the fair market value will be deemed a share capitalization of a number of Class A ordinary shares equal to the product of (i) the number of Class A ordinary shares actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for Class A ordinary shares) and (ii) the quotient of (x) the price per Class A ordinary share paid in such rights offering and (y) the fair market value. For these purposes (i) if the rights offering is for securities convertible into or exercisable for Class A ordinary shares, in determining the price payable for Class A ordinary shares, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) fair market value means the volume weighted average price of Class A ordinary shares as reported during the ten (10) trading day period ending on the trading day prior to the first date on which the Class A ordinary shares trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

Promissory Note — Related Party

The Sponsor agreed to loan the Company an aggregate of up to $250,000 to be used for a portion of the expenses of the Initial Public Offering. The loan was non-interest bearing, unsecured and due at the earlier of December 31, 2025 or the closing of the Initial Public Offering. On December 19, 2025, the Company had borrowed $102,356 under the promissory note which is fully settled, simultaneously with the closing of the Initial Public Offering. Borrowing against the promissory note is no longer available.

Due to Sponsor

On December 19, 2025, the Company had $1,869 borrowings under the promissory note – related party. As of March 31, 2026 and December 31, 2025, the outstanding balance amounting to $0 and $1,869, respectively, were noted as due to Sponsor in the accompanying condensed balance sheets.

Administrative Services Agreement

Commencing on December 17, 2025, the effective date of the Initial Public Offering, the Company entered into an agreement with the Sponsor to pay an aggregate of $10,000 per month for office space, utilities and support services. For the three months ended March 31, 2026, the Company incurred $30,000 in fees for these services, which were included in accrued expenses on the condensed balance sheets.

Related Party Transactions

In order to finance transaction costs in connection with a 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 a Business Combination, the Company would repay the Working Capital Loans. In the event that a Business Combination does not close, the Company may use a portion of the working capital held outside the Trust Account to repay the Working Capital Loans but no proceeds from the Trust Account would be used to repay the Working Capital Loans. Up to $1,500,000 of such Working Capital Loans may be convertible into Private Placement Warrants of the post-Business Combination entity at a price of $1.50 per warrant at the option of the lender. The warrants would be identical to the Private Placement Warrants. As of March 31, 2026 and December 31, 2025, no such Working Capital Loans were outstanding.

immigration, healthcare, taxation, the U.S. regulatory environment, inflation and other areas. For example, during the prior Trump administration, increased tariffs were implemented on goods imported into the U.S., particularly from China, Canada, and Mexico. On February 1, 2025, the U.S. imposed a 25% tariff on imports from Canada and Mexico, which were subsequently suspended for a period of one month, and a 10% additional tariff on imports from China. More recently on April 2, 2025, President Trump signed an executive order imposing a minimum 10 percent baseline tariff on all U.S. imports, with higher tariffs applied to imports from 57 specific countries. The baseline tariff rate became effective on April 5, while tariffs on imports from the 57 targeted nations, ranging from 11 to 50 percent, took effect on April 9. On the same day, President Trump announced a 90-day ‘pause’ on reciprocal tariffs for all but China, which continues to face tariffs as high as 145%. Historically, tariffs have led to increased trade and political tensions, between not only the U.S. and China, but also between the U.S. and other countries in the international community. In response to tariffs, other countries have implemented retaliatory tariffs on U.S. goods.

On July 4, 2025, President Trump signed into law the One Big Beautiful Bill Act (“OBBA”). FASB ASC 740, “Income Taxes”, requires the effects of changes in tax laws to be recognized in the period in which the legislation is enacted. The Company is currently evaluating the impact of the new law. However, none of the tax provisions are expected to have a significant impact on the Company’s unaudited condensed financial statements.

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 Israel-Hamas conflict and subsequent sanctions or related actions, and tariff on imports from foreign countries could adversely affect the Company’s initial Business Combination and its search for any target business with which the Company may ultimately consummate an initial business combination.

Registration Rights

The holders of the founder shares, Private Placement Warrants and the Class A ordinary shares underlying such Private Placement Warrants and Private Placement Warrants and warrants that may be issued upon conversion of the 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 initial Business Combination pursuant to a registration rights agreement signed 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 completion of the initial Business Combination. In addition, Cantor Fitzgerald & Co. may participate in a piggyback registration only during the seven-year period beginning on the effective date of the Initial Public Offering. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

The Company granted the underwriters a 45-day option from the date of the Initial Public Offering to purchase up to an additional 3,000,000 units to cover over-allotments, if any. On December 19, 2025, the underwriters exercised their over-allotment option, closing on the 3,000,000 additional units simultaneously with the Initial Public Offering.

The underwriters were paid in cash an underwriting discount of $4,000,000 simultaneously with the closing of the Initial Public Offering. Additionally, the underwriters are entitled to a deferred underwriting discount of $9,800,000 in the aggregate upon the completion of the Company’s initial Business Combination subject to the terms of the underwriting agreement.

Capital Markets Advisor

The Company has engaged Farvahar Capital LLC (“Farvahar”) to provide capital markets advisory services in connection with the Initial Public Offering, for which it will receive customary advisory fees. Farvahar represents the Company’s interests only, is independent of the underwriters and is not a party to any securities purchase agreement with the Company, the underwriters, or investors in relation to the Initial Public Offering. Farvahar’s fees are offset from the underwriting fees and will not result in any incremental fee to the Company. Pursuant to the agreement, the Company paid Farvahar $184,940 on December 19, 2025, simultaneously with the closing of the Initial Public Offering, which was included in the offering costs.

In addition to that, a deferred fee of up to $980,000 will be paid to Farvahar at the closing of the initial Business Combination (net of 10% of the Underwriters’ non-reimbursable expenses in connection with the initial Business Combination). This deferred fee will only be paid to Farvahar if the Company completes its initial Business Combination.

cast by such shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the applicable general meeting, and pursuant to the Company’s amended and restated memorandum and articles of association, such actions include amending the amended and restated memorandum and articles of association and approving a statutory merger or consolidation with another company.

There is no cumulative voting with respect to the appointment of directors, meaning, following the Company’s initial Business Combination, the holders of more than 50% of the ordinary shares voted for the appointment of directors can elect all of the directors. Prior to the consummation of the initial Business Combination, only holders of the Class B ordinary shares will (i) have the right to vote on the appointment and removal of directors and (ii) be entitled to vote on continuing the Company 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). Holders of the Class A ordinary shares will not be entitled to vote on these matters during such time. These provisions of the amended and restated memorandum and articles of association may only be amended if approved by a special resolution passed by the affirmative vote of at least 90% (or, where such amendment is proposed in respect of the consummation of the initial Business Combination, two-thirds) of the votes cast by such shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the applicable general meeting of the Company.

Share-based Compensation

On February 6, 2026, Petit Monts LLC transferred 25,000 Class B ordinary shares to Nitin Kumar in connection with his appointment to the Board of Directors. The transfer represents consideration for services and is accounted for under FASB ASC Topic 718, “Compensation—Stock Compensation.”

Equity-classified share-based payments are measured at their grant-date fair value. The shares are subject to the same terms and restrictions as the founder Class B ordinary shares, including transferability and redemption limitations that vest upon the completion of a Business Combination. The completion of a Business Combination represents a performance condition, and compensation cost is recognized only when it is probable that the performance condition will be satisfied. As of March 31, 2026, the Company determined that a Business Combination was not probable. Accordingly, no stock-based compensation expense was recognized for the three months ended March 31, 2026.
