A definitive business combination agreement has been signed with Astrum Space Inc, a satellite-to-device broadcast company, valuing Astrum at approximately US$1 billion. Under the terms, Astrum Holding will receive 100 million shares of the combined company, with up to 25.5 million additional performance shares tied to NEASTAR-1 satellite milestones. The deal is backed by a US$168 million founder support letter and BIII's approximately US$172.5 million trust account.

Closing is expected by end of 2026, subject to shareholder and regulatory approvals.
