Additional Definitive Proxy Solicitation Materials

On November 19, 2024, Horizon Space Acquisition I Corp. (the “Company”) filed a definitive proxy statement (as the same may be amended or supplemented, the “Proxy Statement”) for the solicitation of proxies in connection with an extraordinary general meeting in lieu of an annual general meeting of the Company’s shareholders (the “Extraordinary Meeting”) to be held at 9:00 a.m. Eastern Time, December 20, 2024 in connection with, among the others, the extension of the date by which the Company has to consummate a business combination.

On December 20, 2024, the Company issued a press release announcing revised contribution to trust account in connection with the MAA Amendment Proposal (as defined in the Proxy Statement). On the same day, the Company issued a press release announcing, among other things, the adjournment of the Extraordinary Meeting (the “Adjournment”) to December 23, 2024, at 9:00 a.m. Eastern Time (the “Rescheduled Meeting Time”), in order to allow additional time for the Company to engage with its shareholders. The record date for determining the Company shareholders entitled to receive notice of and to vote at the Meeting remains the close of business on November 14, 2024 (the “Record Date”). Shareholders as of the Record Date who have previously submitted their proxies or otherwise voted and who do not want to change their vote need not take any action. Shareholders who have not yet done so are encouraged to vote as soon as possible. As a result of the Adjournment, the deadline for the Company’s public shareholders to deliver their redemption requests is extended to prior to the vote at the rescheduled Meeting.

There is no change to the location, the purpose or any of the proposals to be acted upon at the Extraordinary Meeting. The physical location of the Extraordinary Meeting remains at the offices of Robinson & Cole LLP, 666 Third Avenue, 20th Floor, New York, NY 10017, and virtually via teleconference using the dial-in information: +1 813-308-9980 (Access Code: 173547).
