SpaceX Welcomes a New Challenger: Rocket Lab Spends $8 Billion to Build an “Aerospace Closed Loop”

Rocket Lab announced the acquisition of satellite communications company Iridium Communications for approximately $8 billion. The deal not only gives the company a global satellite network, spectrum resources, and more than 2.5 million subscribers, but also means it has formally moved into direct competition with SpaceX and Starlink.

Rocket Lab (RKLB.O) announced on Monday that it will acquire satellite communications service provider Iridium Communications (IRDM.O) for approximately $8 billion, with the transaction expected to be completed by mid-2027. Under the agreement, Iridium Communications shareholders will receive $27 in cash and Rocket Lab stock for each share, totaling $54, representing a 24.1% premium over the closing price from the previous trading day.

The acquisition will integrate Rocket Lab’s rocket launch and satellite manufacturing businesses with Iridium Communications’ global L-band satellite network, licensed spectrum resources, and more than 2.5 million subscribers from government, defense, aviation, maritime, and commercial markets, giving the company a vertically integrated model similar to that of SpaceX (SPCX.O) and Starlink.

Rocket Lab founder and CEO Peter Beck said the company is not only acquiring a highly profitable business and an almost entirely new satellite constellation, but more importantly gaining valuable spectrum resources. If these assets were built on its own, it could take years and require investments of billions of dollars.

He also said the transaction is “a defining moment for the aerospace industry, and the beginning of a new era of strategically accelerated growth.”

The company said that after the acquisition is completed, it will further expand Iridium Communications’ Direct-to-Device business and enter more space-based service markets. A key foundation for Rocket Lab to build its own satellite constellation—the medium-lift reusable rocket Neutron—is expected to make its first flight in the fourth quarter of 2026.

Accelerating Expansion of Space Systems Business

This is Rocket Lab’s fourth acquisition announced this year. The company said acquiring Iridium Communications is a “shortcut” to rapidly expand its space applications business, while its space systems business has already become the company’s main source of revenue.

According to FactSet projections, for the quarter ending June, Rocket Lab’s launch services revenue is expected to be approximately $71 million, while revenue from the space systems business is expected to reach $162 million.

Micah Walter Range, president of aerospace consultancy Caelus Partners, said the acquisition gives Rocket Lab immediate access to a mature customer base and distribution network, and its value may even exceed the hardware and spectrum resources obtained in the deal.

William Blair analyst Louie DiPalma said the transaction is “of very significant strategic importance,” and that Rocket Lab will use it to gain a global L-band satellite network, spectrum licensing, government contracts, and more than 2.5 million subscribers.

To fund the cash portion, Rocket Lab has obtained $3.6 billion bridge loan commitments provided by Deutsche Bank and Wells Fargo, and will also use its cash on hand, together with newly added debt and equity financing, to complete the transaction.

Rising Momentum in Aerospace Industry Consolidation

Earlier this month, SpaceX completed the world’s largest IPO on a global scale, raising approximately $86 billion, further boosting investor attention on the aerospace sector. Meanwhile, SpaceX continues to expand its satellite communications and artificial intelligence infrastructure businesses.

Iridium Communications was founded by Motorola in the late 1980s and is one of the earliest companies to build a global low-Earth-orbit satellite communications network. In 1999, the company went through bankruptcy, and then completed a turnaround, developing into a profitable company offering communications services to government, aviation, maritime, and industrial customers.

In February, Iridium Communications CEO Matthew Desch said the company has proven it is not “a business in decline,” and believes its NTN Direct service will complement the Direct-to-Device products developed by SpaceX, Amazon (AMZN.O), and AST SpaceMobile (ASTS.O).

Analysts noted that since Amazon announced its acquisition of Globalstar (GSAT.A) in April, the market has been speculating that Iridium Communications could become a potential acquisition target, while SpaceX has also reached an agreement to acquire EchoStar’s (ECHO.O) spectrum resources.
