Rocket Lab agrees to acquire Iridium in $8B cash-and-stock deal

Rocket Lab has agreed to acquire Iridium Communications in a deal valued at approximately $8 billion, combining cash and stock.

Iridium operates one of the most recognized low-Earth orbit satellite constellations in the world. Its network provides voice and data communications coverage across the entire globe, including oceans, polar regions, and other areas where traditional cell towers simply don’t reach.

Rocket Lab, which trades on Nasdaq under the ticker RKLB, has been on an acquisition tear over the past year. The company closed its purchase of Geost for $275 million in August 2025 and announced a deal for Motiv Space Systems slated for 2026. It also acquired Mynaric, a laser communications company, as part of its broader push toward vertical integration across the space supply chain.

Iridium has been valued at a sales multiple of roughly 7.4x in comparative evaluations alongside other satellite communications companies, which gives some context for how the price tag was derived.

Rocket Lab currently boasts a launch contract backlog exceeding $2.2 billion heading into 2026. Adding Iridium’s recurring revenue from satellite communications services would give the company a fundamentally different financial profile, one with more predictable cash flows alongside the lumpier economics of launch contracts.

Iridium serves maritime, aviation, government, and IoT connectivity in remote areas where reliability is non-negotiable, distinguishing its market from SpaceX’s Starlink, which has expanded aggressively with consumer broadband ambitions.

An $8 billion cash-and-stock deal of this size raises immediate questions about dilution and financing. Stock-based acquisitions at this scale typically require Rocket Lab to issue a significant number of new shares, which would dilute existing shareholders. The cash component, meanwhile, likely necessitates substantial debt financing or a drawdown of reserves.
