Postponement of Shareholders Meeting

Launch One Acquisition Corp. (the “Company”) has determined to postpone the extraordinary general meeting in lieu of an annual general meeting of the shareholders of the Company (the “Meeting”), initially scheduled to occur on Tuesday, July 7, 2026 at 10:00 a.m., Eastern Time, to Friday, July 10, 2026, at 10:00 a.m., Eastern Time. As previously disclosed, the purpose of the Meeting is to, among other things, approve an amendment to the Company’s amended and restated memorandum of association and articles of association, to extend the date by which the Company must consummate an initial business combination from July 15, 2026 to January 15, 2027 (or such earlier date as determined by the Company’s board of directors (the “Extension Amendment Proposal”)). The Meeting will be held at the offices of Ellenoff Grossman & Schole LLP, located at 1345 Avenue of the Americas, 11^thFloor, New York, New York 10105. The deadline by which shareholders must exercise their redemption rights in connection with the vote to approve the Extension Amendment Proposal at the Meeting has been extended to Wednesday, July 8, 2026, at 5:00 p.m., Eastern Time, which is two business days prior to the Meeting.

Participants in the Solicitation

The Company and its directors and executive officers and other persons may be deemed to be participants in the solicitation of proxies from the Company’s shareholders in respect of the Meeting and related matters. Information regarding the Company’s directors and executive officers is available in the definitive proxy statement on Schedule 14A (the “Proxy Statement”). Additional information regarding the participants in the proxy solicitation and a description of their direct and indirect interests are contained in the Proxy Statement.

No Offer or Solicitation

This communication shall not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any jurisdiction in which the offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction. No offering of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act.

Additional Information

The Company has filed the Proxy Statement with the U.S. Securities and Exchange Commission (the “SEC”) in connection with the Meeting to consider and vote upon the Extension Amendment Proposal, the Auditor Ratification Proposal and other matters and, beginning on or about June 12, 2026, mailed the Proxy Statement and other relevant documents to its shareholders as of May 15, 2026, the record date for the Meeting. The Company’s shareholders and other interested persons are advised to read the Proxy Statement and any other relevant documents that have been or will be filed with the SEC in connection with the Company’s solicitation of proxies for the Meeting because these documents contain important information about the Company, the Extension Amendment Proposal, the Auditor Ratification Proposal and related matters. Shareholders may also obtain a free copy of the Proxy Statement, as well as other relevant documents that have been or will be filed with the SEC, without charge, at the SEC’s website located at www.sec.gov or by directing a request to: Launch One Acquisition Corp., 180 Grand Avenue, Suite 1530, Oakland, CA 94612, Telephone No.: (510) 200-8778.
