The transaction is expected to close by the end of 2026, subject to regulatory and shareholder approvals, and other customary closing conditions. After the transaction, assuming no BIII shareholders elect to have their BIII shares redeemed for cash as permitted, existing shareholders of Astrum will hold over 80% of the combined company.

Over the years, the space sector has evolved into one of today’s most dynamic industries and continues to play an increasingly important role in everyday life. This partnership with Astrum reflects our belief in the power of enabling technologies to create meaningful impact.”

Mr. Michael Do, President and Chief Executive Officer of Astrum Space Inc, said: “Astrum has reached an important inflection point. We have assembled the spectrum, orbital resources and satellite infrastructure to develop a differentiated S2D broadcast platform across Asia-Pacific.
