Rocket Lab announced on Monday that it will acquire Iridium Communications in a cash and stock transaction valuing Iridium at approximately $8 billion. RKLB shares rose 16 percent. Iridium shareholders receive $54 per share: $27 in cash and the remainder in Rocket Lab stock through a collar-banded exchange ratio between $67.50 and $112.50 per RKLB share. Deutsche Bank and Wells Fargo are providing a $3.6 billion 364-day senior secured bridge loan to fund the cash portion. The deal is expected to close in mid-2027.
The acquirer had $680 million in trailing twelve-month revenue. The target reported $871 million in 2025 revenue and $218.8 million in Q1 2026. Rocket Lab is buying a company that out-earns it.
The Stack
What Rocket Lab owns after this closes is unusual. It manufactures satellites. It launches them on Electron, the second most frequently launched U.S. rocket after SpaceX's Falcon 9. It is building Neutron, a medium-lift reusable vehicle scheduled for first launch later this year. And it will operate a 66-satellite low Earth orbit constellation serving 2.55 million subscribers across government, defense, aviation, maritime, and commercial markets, generating $480 to $490 million in annual OIBDA.
From component fabrication to launch to orbit to spectrum to subscriber. No other company outside SpaceX controls the full chain.
The Frequency That Survived
Iridium cost $6 billion to build in the 1990s. The original Motorola-backed constellation launched 66 satellites, promised global voice coverage, and went bankrupt in 2000. A group of investors bought the entire company for $25 million.
The same business is now valued at $8 billion. The asset is not the satellites. The originals were deorbited and replaced between 2017 and 2019 through Iridium NEXT, which put 75 new satellites into orbit across eight SpaceX Falcon 9 launches under a $492 million contract. Hardware wears out.
What survived bankruptcy, a fire sale, and two complete hardware refreshes is the spectrum. Iridium holds globally harmonized L-band frequencies between 1,616 and 1,626.5 megahertz, negotiated through decades of international coordination. This allocation cannot be replicated. It cannot be purchased again. The satellites deliver the signal. The frequency is the franchise.
The Captive Launch
SpaceX built its way to vertical integration. It developed Falcon 9, launched Starlink on it, and now operates both the rocket and the constellation. The vehicle created its own demand.
Rocket Lab inverted the sequence. It acquired the demand first. When Iridium's satellites next need replacing, the launch contract does not go to SpaceX. It goes to Neutron. Rocket Lab did not outbid anyone for Iridium's next launch campaign. It bought the customer.
Iridium paid SpaceX $492 million for eight Falcon 9 flights between 2017 and 2019. That future revenue stream now belongs to Rocket Lab. Peter Beck purchased a guaranteed launch manifest for the next constellation refresh, insuring Neutron's production schedule against the uncertainty of bidding in the open market.
A launch company with $680 million in revenue took on $3.6 billion in bridge financing to acquire $871 million in revenue and nearly $500 million in annual operating income. The constellation's subscribers service the debt that funded the acquisition that secures the launch demand that justifies the rocket that replaces the constellation. The circle closes.
