Item 5.07 Submission of Matters to a Vote of Security Holders. On June 11, 2026, the Company held an Extraordinary General Meeting of shareholders (the “Extraordinary General Meeting”). As of the close of business on May 13, 2026, the record date for the Extraordinary General Meeting, there were 5,025,517 ordinary shares outstanding and entitled to vote. Holders of 4,260,752 ordinary shares were present in person or represented by proxy at the Extraordinary General Meeting, constituting a quorum. At the Extraordinary General Meeting, holders of the Company’s outstanding ordinary shares in attendance (represented in person or by proxy) voted on two proposals presented, the Extension Proposal and the Adjournment Proposal, each as described in the proxy statement dated May 18, 2026 (the “Proxy Statement”). The final voting results for the proposal submitted to the shareholders at the Extraordinary General Meeting were as follows: Proposal No. 1 - Extension Proposal To amend, by special resolution, the Company’s Amended and Restated Memorandum and Articles of Association to extend the date by which the Company has to consummate a business combination up to twelve times, with each such extension being for a one-month period, from June 20, 2026 to June 20, 2027. The Extension Proposal required a special resolution under Cayman Islands law, being the affirmative vote of at least a two-thirds majority of the votes cast by the holders of the issued and outstanding ordinary shares present in person or represented by proxy and entitled to vote thereon at the Extraordinary General Meeting. The Extension Proposal has been approved by the following votes: For: 2,993,175 Against: 1,267,577 Abstain: 0 Broker Non-Votes: 0 Proposal No. 2 - Adjournment Proposal To approve, by ordinary resolution, the adjournment of the Extraordinary General Meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies if there were insufficient votes to approve the Extension Proposal. The Adjournment Proposal received the following votes: For: 2,993,175 Against: 1,267,577 Abstain: 0 Broker Non-Votes: 0 As disclosed in the Company’s Proxy Statement, the Adjournment Proposal would only be presented at the Extraordinary General Meeting if there were insufficient votes to approve the Extension Proposal. Although proxies were solicited and votes were tabulated with respect to the Adjournment Proposal, because the Extension Proposal received sufficient votes for approval, the Adjournment Proposal was not presented at the Extraordinary General Meeting and no action was taken with respect to such proposal.

Item 8.01 Other Events. In connection with the shareholder votes at the Extraordinary General Meeting, holders of 1,507,257 ordinary shares of the Company properly exercised their right to redeem their shares for a pro rata portion of the funds held in the Trust Account.
