Horizon Space Acquisition II Corp. extended the deadline to complete its initial business combination by one month, from April 18, 2026 to May 18, 2026. This is the third of up to twelve one‑month extensions allowed under its charter amendment.
The sponsor deposited a $50,000 extension fee into the company’s trust account and received an unsecured promissory note for the same amount. The note bears no interest and is due at the business combination or the company’s expiry, and may be converted into private units at $10.00 per unit.

Each unit includes one PubCo ordinary share and one series A preferred share that converts into one-third of a PubCo ordinary share six months after closing.

The note bears no interest and is due upon either completion of the business combination or the company’s expiry date.
