Iridium Communications (IRDM) details timeline and strategy for Rocket Lab acquisition

Rhea-AI Filing Summary

Iridium Communications Inc. describes progress on its proposed acquisition by Rocket Lab Corporation. Regulatory and licensing filings are underway and are described as proceeding on schedule. The companies are currently targeting a mid-2027 closing, while exploring whether the timetable can be accelerated; until then, it remains business as usual for Iridium.

Early relationship-building has begun, including a two-day visit by Rocket Lab executives to Iridium’s facilities to better understand Iridium’s network, partner-focused business model and growth pillars. Management highlights potential combined opportunities across IoT and NTN Direct, Iridium’s PNT platform (including cybersecurity applications), national security missions, and aviation safety via Aireon and communications services, framing the combination as potentially “1 + 1 = 3.”

Rocket Lab has filed a Registration Statement on Form S-4 that includes Iridium’s proxy statement/prospectus, which is not yet effective. Iridium stockholders will be asked to approve transaction-related proposals, and investors are urged to read the Form S-4 and related proxy statement/prospectus carefully when available, as they will contain important information and risk factors regarding the transaction and its completion.

Registration Statement on Form S-4 regulatory

"Rocket Lab has filed a Registration Statement on Form S-4 that includes the proxy statement"

A registration statement on Form S-4 is a formal filing with the U.S. Securities and Exchange Commission used when a company issues shares or other securities as part of a merger, acquisition, exchange offer or similar corporate deal. It bundles the transaction terms, financial statements, risk factors and shareholder vote materials so investors can assess the deal; think of it as a detailed prospectus or buyer’s packet that explains what you would own and how the deal could change your stake.

proxy statement/prospectus regulatory

"the proxy statement of Iridium that will also constitute a prospectus of Rocket Lab"

A proxy statement or prospectus is a document that companies send to shareholders to provide important information about upcoming decisions or investments, such as voting on company issues or offering new shares to the public. It helps investors understand the details and risks involved, enabling them to make informed choices about their ownership or involvement with the company.

participants in the solicitation regulatory

"may be considered participants in Iridium’s solicitation"

People or firms who actively seek to influence shareholders’ choices in a corporate action—such as a vote, merger, proxy contest, or tender offer. This can include company insiders, advisers, bankers, lawyers and professional solicitors who contact investors to persuade them. Investors care because knowing who is doing the persuading reveals potential conflicts, resources and credibility behind the campaign, much like checking who is organizing a political campaign before accepting its message.

forward-looking statements regulatory

"This communication contains “forward-looking statements” within the meaning of the federal securities laws"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

merger agreement regulatory

"other circumstances that could give rise to the termination of the merger agreement"

A merger agreement is a binding contract that lays out the exact terms for two companies to combine, including the price, what each side will deliver, and the conditions that must be met before the deal is completed. Investors care because it sets the timetable, payouts and risks — like a blueprint or prenup that shows whether the deal is likely to close, how ownership will change, and what could cancel or alter the payout they expect.

Filed by Iridium Communications Inc.

Pursuant to Rule 425 Under the Securities Act of 1933

and deemed filed pursuant to Rule 14a-12

under the Securities Exchange Act of 1934

Subject Company: Iridium Communications Inc.

Commission File No.: 001-33963

The following communication is an excerpt of a transcript of a video of Matthew J. Desch, Chief Executive Officer of Iridium Communications Inc. (“Iridium”) circulated to employees of Iridium on August 13, 2026 in connection with the proposed acquisition of Iridium by Rocket Lab Corporation:

 

So, I've had a lot of questions about the Rocket Lab acquisition while I've been out here and that's totally appropriate. Just sort of a quick update on that. Regulatory filings are underway right now, which means a lot of paperwork and work towards approvals for licenses and that sort of thing. Thanks to our legal team and finance team who are bearing the really brunt of that activity. My thanks to all of them. There's just a lot of areas that you have to go through to get approvals for an acquisition, a major merger like this and those are proceeding on schedule right now. We're still expecting a mid-2027 close, though a lot of effort to see if we can possibly accelerate and drive that to close sooner. But for now, I think that's still a good timeline right now to shoot for. Of course, it's business as usual until then, though, we're starting to engage a little bit with the senior Rocket Lab team. 

Last week, about 15 Rocket Lab execs traveled to Northern Virginia to interact with us over 2 days, to see our facilities at headquarters, the Aireon site and the SNOC. I think they were quite impressed with all the people and activities that they met. I would say this was mostly a get to know you kind of session. It was really early stages. We're not into any kind of detailed integration planning which would happen, really won't start for a couple months, but it was a chance for us to open lines of communication, talk about potential, get to understand, sort of, each other a little bit better. And I think it was a really successful meeting. 

I would say the overlying theme is that we have a lot of opportunity in the future together and you know, as they like to say, it's 1 + 1 = 3. I think that we shared a lot of ideas about how we think we could continue to grow even faster than our current expectations are. And you know, they want to be a fully integrated space powerhouse. I think, you know, I think we see ourselves as a really important component of that. A platform on which to grow the “application space” as they would call it which, you know, combined with their really successful launch business and growing into the heavier lift platforms like the Neutron as well as their satellite capabilities - which are you know, growing in success as well - we think we can scale and accelerate the deployment of new services, which would drive growth really within and around the growth pillars we've talked about before. IoT and NTN Direct, and the success we've had as a leader in IoT and the satellite industry; the evolution of our very powerful PNT platform into more applications and services, including cyber security; the potential we both bring in terms of national security missions and expanding our  growing business there; and of course in aviation safety where we really believe we can differentiate ourselves with Aireon and with our communication capabilities. 

 

So, we talked a bit about our respective cultures and the way we do things, and I think Rocket Lab better appreciates our business model as a supplier of services to the many partners. You know really our partner orientation, how important our growing partner base is to us, and to our growth plans. The reliability of our network and the importance we share in having the best network possible and the best services possible, and really many other things about us. I think we're also better understanding of their capabilities and expertise.  And think really the combination could be very, very powerful. 

I'll say, we liked everyone we met. The Rocket Lab people, like us, are smart.  They're driven and they’re as passionate as we are really about the future and about the potential of our business in this industry. I think it was a great first get together and I look forward to getting to more detail about integration planning when it's appropriate, perhaps later this year. 

So, I'm getting a lot of other great questions while I'm out here in Arizona and I welcome them. I'm glad to answer everything I can at this point and I look forward to providing more information and future Teams Talks as it becomes available. You know, I'm sensing a lot of excitement and support about this, which is appropriate. And you know, I've heard really the same thing from externally, from our partners and from the industry, and I'm looking forward to getting on with it. So anyway, as always, you’re welcome to send any specific questions you might have that we haven't answered and I look forward to a continued great 2026 and the potential of the future that we're driving right now. 

Thanks for listening and have a good one. Take care.
