Why RKLB Wants IRDM

Rocket Lab said the acquisition will combine its launch and satellite manufacturing capabilities with Iridium's global satellite communications network and L-band spectrum, creating a vertically integrated space company that designs, builds, launches and operates its own satellite constellations.

The company said the deal gives it an immediate foothold in space-based applications, including satellite internet of things, direct-to-device communications, positioning, navigation and timing services, while adding a recurring revenue business.

“By marrying Iridium's deep heritage, trusted infrastructure, and highly sought-after spectrum with Rocket Lab's extensive and proven launch and manufacturing capabilities, we have the capability to unlock entirely new markets,” said Rocket Lab CEO Peter Beck.

Rocket Lab also said owning Iridium's network is expected to eliminate third-party launch costs for future constellation deployments and replenishment.

“Rather than simply continuing the Iridium network, Rocket Lab will build upon it to scale into untapped markets and pioneer new space-based services to the benefit of global customers,” Rocket Lab said.

What IRDM Shareholders Will Get

Under the agreement, Iridium shareholders will receive $27 in cash and Rocket Lab shares for each Iridium share they own. The stock portion will be determined by an exchange ratio subject to a collar based on Rocket Lab's share price.
