Rocket Lab Expands Into Satellite Communications

Following the announcement, RKLB stock jumped nearly 10%. The deal would transform Rocket Lab into a more vertically integrated space company with launch, satellite manufacturing and communications capabilities.

The acquisition combines Rocket Lab’s launch and satellite manufacturing business with Iridium’s global satellite communications network, L-band spectrum and partner ecosystem. The combined company aims to design, build, launch and operate its own satellite constellations while expanding recurring communications revenue.
