Horizon Space Acquisition I Corp. (HSPOF) announced a definitive business combination agreement with ArcheNova Biotech Corp. Under the proposed structure, a newly formed Cayman Islands company, ArcheNova Technology Co., Ltd. (PubCo), would become the parent. HSPO would survive the first merger as a wholly owned PubCo subsidiary, and ArcheNova Biotech would survive the second merger as a wholly owned PubCo subsidiary. Upon completion, shareholders of both companies would receive PubCo ordinary shares.
The transaction is expected to close in the first quarter of 2027, subject to regulatory and shareholder approvals and other customary closing conditions; PubCo ordinary shares are expected to trade on Nasdaq after closing. Both companies’ boards unanimously approved the agreement. Dr. Lim Sai Kiang is expected to lead PubCo as Chief Executive Officer and Chief Scientist, with Liu Ye as Chief Financial Officer. ArcheNova says it is advancing five product candidates; its psoriasis candidate completed a Phase I study in 10 healthy volunteers and is being prepared for Phase II.
Horizon Space Acquisition I Corp. entered into a $500,000 unsecured promissory note with its sponsor to provide general working capital. The note bears no interest and is due upon the earlier of completing an initial business combination or the expiry of the company’s term.
The sponsor may, at its option, convert 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 upon a business combination. The note was issued as an unregistered security under Section 4(a)(2), and any units issued on conversion will be restricted from transfer until the business combination and will carry registration rights.
Horizon Space Acquisition I Corp. issued a supplement to its proxy materials to correct an arithmetic error in the estimated SPAC redemption price. The company now estimates public shareholders who redeem in connection with the April 20, 2026 extraordinary general meeting would receive approximately $12.725 per share, up from the previously stated $11.66, based on funds in the trust account as of the record date.
The meeting will consider extending the deadline to complete a business combination to June 12, 2027 and a related trust agreement amendment. Using the corrected estimate and a closing market price of $12.24 on the record date, the company notes that redemption would yield about $0.49 more per share than an open-market sale if that market price remained unchanged.

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.
