Horizon Space Acquisition I Corp. files its annual report as a SPAC that has not yet completed an initial business combination and terminated its prior merger agreement with Squirrel Enlivened entities effective October 3, 2025 without any termination fee. The company has repeatedly extended its combination deadline through shareholder votes and now has until April 27, 2026, with significant redemptions at each extension. After redemptions, the Trust Account held $1,179,991 as of December 31, 2025, while cash outside the trust was $35,894, and the company reported 2025 net income of $203,618 driven by interest on trust investments.

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.
