The following email was sent by Matthew J. Desch, the Chief Executive Officer of Iridium Communications Inc. (“Iridium”), to Iridium’s employees on June 29, 2026 in connection with the proposed acquisition of Iridium Communications Inc. by Rocket Lab Corporation:
To: All Iridium Employees
From: Matt Desch
Subject: An Exciting New Chapter for Iridium
Iridium Team,
This morning, we announced that Iridium has entered into a definitive agreement to be acquired by Rocket Lab, creating a vertically integrated space powerhouse that designs, builds, launches, and operates its own satellite networks, delivering critical communications capabilities to millions of users worldwide. This is an exciting moment for our Company and one that reflects the tremendous business we have all worked so hard to build and drives value for our shareholders.
Together, we have transformed Iridium into a world leading provider of mission-critical satellite applications, including reliable communications, resilient PNT, aviation safety, and mission services. Iridium is delivering reliable connectivity that our customers depend on everyday – whether they’re operating in the world’s most remote locations, supporting national security missions, keeping aircraft and ships connected, or responding to emergencies.
Rocket Lab is a natural fit for Iridium. The talented team at Rocket Lab has built one of the most innovative and respected companies in our industry, with strong global capabilities across launch and space systems. Importantly, Rocket Lab’s management team has great respect for our company, including Iridium’s unique offerings and capabilities, and all of you who have made our systems and solutions possible. Rocket Lab recognizes the strength of our technology and our customer relationships, and they share our commitment to innovation and mission execution.
We’ve built an amazing company over the last 25+ years, but as we looked into the future, we see increasing competition from some very well-funded companies. To continue to compete, innovate, and grow, we need to be vertically integrated across launch, satellites, manufacturing, and services. This will let us bring new services to the market and sustain them competitively. By bringing our companies together, we will have the ability to invest better in our future, expand what we can offer our customers, and continue to lead in areas that matter most. Specifically, we expect to:
| · | Accelerate investment in upgrading Iridium’s network and next-generation capabilities; |
| · | Expand solutions for our commercial, government and defense customers; |
| · | Unlock new opportunities for innovation across the space value chain; and |
| · | Continue delivering the reliable, mission-critical communications our customers expect from us. |
What Happens Next
While today's announcement is significant, it is just the first step in the process. The transaction is expected to close in mid-2027, subject to approval by Iridium shareholders, receipt of regulatory approvals, and satisfaction of other customary closing conditions. Until the transaction is completed, it is business as usual and Iridium and Rocket Lab will continue to operate as separate, independent companies. Please stay focused on advancing our priorities and serving our customers, as always.
There are many important decisions to be made regarding how we will bring our two companies together following completion of the transaction, and we recognize you will have questions about what this means and the path forward. In the Teams Talk below, I share my perspective, what to expect next and how we’ll stay aligned at things progress. Please take a moment to watch.

Let’s keep up the momentum!
