Item 5.07 Submission of Matters to a Vote of Security Holders.

At the Extraordinary General Meeting held on December 30, 2025, there were 3,214,886 ordinary shares of Metal Sky Star present in person or represented by proxy, representing 98.45% of the outstanding ordinary shares of Metal Sky Star as of December 3, 2025, the record date for the Extraordinary General Meeting, and constituting a quorum for the transaction of business. At the Extraordinary General Meeting, each of the proposals described below was approved by the Company’s shareholders of record. The final results for the votes regarding each proposal are set forth in the following tables. Each of the proposals is described in detail in the Company’s Proxy Statement.

Proposal 1 (Extension Proposal):

To amend the 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 (12) times (the “Extended Date”), each such extension for an additional one-month period (each an “Extension”), from January 5, 2026 to January 5, 2027, and waive the monthly extension fee, by amending the Amended and Restated Memorandum and Articles of Association to delete the existing Article 36.2 thereof and replacing it with the new Article 36.2 in the form set forth in Annex A of the accompanying Proxy Statement.
