Horizon Space Acquisition I Corp. has called an extraordinary general meeting on April 20, 2026 to ask shareholders to extend its deadline to complete a business combination. The MAA Amendment and Trust Amendment Proposals would move the cut-off to June 12, 2027, avoiding an automatic wind-up on April 27, 2026.
Public shareholders can redeem their shares in connection with the amendments for cash equal to their pro rata share of the trust. Based on approximately $1.19 million in the trust as of March 26, 2026, this is about $11.66 per public share, versus a closing OTCQB price of $12.24. HSPO has a non-binding letter of intent with Sandbox Inc., a California robotics and AI company, but does not expect to complete any deal before the current deadline. If the extensions fail and no merger closes by April 27, 2026, HSPO will redeem public shares and liquidate, leaving warrants and rights worthless.

On January 26, 2026, the company issued an unsecured promissory note for $500,000 to Horizon Space Acquisition I Sponsor Corp. to provide general working capital until it completes its initial business combination.
The note bears no interest and is due on the earlier of the business combination or the company’s term expiry. The sponsor may choose to convert the outstanding principal into private units at $10.00 per unit, with each unit consisting of one ordinary share, one warrant and one right to receive one‑tenth of an ordinary share. Any units issued on conversion will be restricted from transfer until the initial business combination and will have registration rights.

Net income was driven by interest on trust investments, totaling $149,028 for the quarter and $296,369 for the first nine months, down sharply from the prior year as trust assets declined.

Management states there is substantial doubt about HSPO’s ability to continue as a going concern.
