The Class A Ordinary Shares issued in connection with the Conversion are subject to the same restrictions applicable to the Class B Ordinary Shares prior to the Conversion, including, certain transfer restrictions, waiver of redemption rights and the obligation to vote in favor of an initial business combination as described in the final prospectus filed with the Securities and Exchange Commission (the “SEC”) by the Company on July 12, 2024 (File No. 333-280188) in connection with the Company’s initial public offering. Following the Conversion, there were 28,749,999 Class A Ordinary Shares issued and outstanding and 1 Class B Ordinary Share issued and outstanding.

The Class A Ordinary Shares issued upon the Conversion have not been registered under the Securities Act in reliance on the exemption from registration provided by Section 3(a)(9) thereof.

Item 8.01. Other Events.

Form of Non-Redemption Agreement

On June 10, 2026, the Company filed a definitive proxy statement on Schedule 14A (the “Proxy Statement”) with the SEC for the purpose of calling an extraordinary general meeting in lieu of an annual meeting of the shareholders of the Company (the “EGM”) to vote on, among other things, a proposal to amend the Company’s amended and restated memorandum and articles of association (“Articles”) to extend the date by which the Company must consummate a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination (a “business combination”) from July 15, 2026 to January 15, 2027 (the “Extension Amendment Proposal”).

In connection with the EGM, the Company and the Sponsor intend to enter into agreements (collectively, the “Non-Redemption Agreements”) with one or more shareholders of the Company (each, an “Investor”) in exchange for such Investors agreeing (i) not to redeem (or to validly rescind any redemption requests previously made in respect of), and (ii) to vote or consent (in person or by proxy) in favor of the Extension Amendment Proposal, with respect to a to-be-determined number of the Class A ordinary shares (such shares subject to the Non-Redemption Agreements, the “Non-Redeemed Shares”), at the EGM.

In exchange for the foregoing commitments by the Investors, the Sponsor anticipates agreeing to transfer to such Investors promptly following the closing of the Company’s initial business combination, a certain number of Class A ordinary shares of the Company held by the Sponsor, at a ratio to be negotiated between the parties.

The Non-Redemption Agreements shall terminate on the earliest of (i) the failure of the Company’s shareholders to approve the Extension Amendment Proposal at the EGM, (ii) the fulfillment of all obligations of the parties under the Non-Redemption Agreement, (iii) the liquidation or dissolution of the Company, (iv) the mutual written agreement of the parties to the Non-Redemption Agreement, and (v) the exercise by an Investor of its redemption rights with respect to the Non-Redeemed Shares or the failure by such Investor to vote in favor of the Extension Amendment Proposal at the EGM.

The Non-Redemption Agreements, if entered into, are expected to increase the likelihood that the Extension Amendment Proposal is approved by the Company’s shareholders at the EGM and are expected to increase the amount of funds that remain in the Company’s trust account established in connection with the Company’s initial public offering following the EGM. The Company and the Sponsor may enter into additional, similar non-redemption agreements in connection with the EGM.

The foregoing summary of the Non-Redemption Agreements does not purport to be complete.

Additional Information and Where to Find It

The Company has mailed the Proxy Statement to its shareholders of record as of May 15, 2026 on or about June 12, 2026. Investors and security holders of the Company are advised to read the Proxy Statement and any amendments or supplements thereto, including the definitive additional materials filed on June 25, 2026, because these documents contain or will contain important information about the Extension Amendment Proposal and the Company.
