Rocket Lab cleared a major U.S. antitrust milestone for its proposed acquisition of Iridium Communications. The Hart-Scott-Rodino (HSR) Antitrust Improvements Act waiting period expired on August 12, 2026.
Rocket Lab filed a Form S-4 registration statement with the SEC regarding securities for Iridium shareholders. The company also submitted applications to the FCC to transfer Iridium’s operating licenses.
The transaction requires Iridium stockholder approval and remains subject to customary closing conditions. Management expects to complete the acquisition in mid-2027.
