Provides update on strategic initiatives; Pending acquisition by Rocket Lab expected to close in mid-2027

MCLEAN, Va., July 22, 2026 /PRNewswire/ -- Iridium Communications Inc. (NASDAQ:IRDM) ("Iridium" or the "Company"), a leading provider of global voice, data, and PNT satellite services, today reported financial results for the second quarter of 2026.

Pending Transaction with Rocket Lab

On June 28, 2026, the Company entered into a definitive agreement with Rocket Lab Corporation under which Rocket Lab will acquire the Company. The transaction is expected to be completed in mid-2027, subject to approval by Iridium stockholders and the satisfaction of other customary closing conditions.

In light of the pending transaction, the Company does not intend to hold conference calls to discuss its quarterly financial results or to update or provide financial guidance.

Second Quarter 2026 Financial Results

Iridium reported second quarter total revenue of $225.2 million, a 4% increase versus the comparable period of 2025. Service revenue, which primarily represents recurring revenue from Iridium's growing subscriber base, grew 4% from the year-ago period and was 72% of total revenue for the second quarter of 2026.

"Iridium's global network and expanding service portfolio continues to be the gold standard for mission critical applications," said Matt Desch, CEO, Iridium. "We believe vertically integrating with Rocket Lab's industry leading launch and satellite capabilities will allow the combined company to realize even greater ambitions to solve important connectivity challenges around the world."

Income from Operations

Net income was $9.7 million, or $0.09 per diluted share, for the second quarter of 2026, as compared to net income of $22.0 million, or $0.20 per diluted share, for the second quarter of 2025. The decrease was primarily the result of increases in transaction costs. Operational EBITDA ("OEBITDA")⁽¹⁾ for the second quarter of 2026 was $119.1 million, as compared to $121.3 million for the prior-year period. The year-over-year OEBITDA was lower due primarily to a $3.9 million increase in accrued expenses related to a change in practice to pay annual incentive compensation entirely in cash rather than a mix of equity and cash, which the Company previewed in prior quarters.

Subscribers

The Company ended the second quarter with 2,627,000 total billable subscribers, up from 2,483,000 for the year-ago period and 2,555,000 for the quarter ended March 31, 2026. Total billable subscribers grew 6% year-over-year, led by growth in commercial IoT.

Business Highlights

Service – Commercial

Commercial service remained the largest part of Iridium's business, representing 59% of the Company's total revenue during the second quarter. Commercial service revenue was $133.7 million, up 4% from the comparable period last year. Commercial IoT data revenue increased $2.3 million, or 5%, in the latest period, driven by a 9% increase in billable subscribers. Hosted payload and other data service revenue increased $2.0 million, or 14%, primarily due to increases in other data services contracts. Commercial voice and data revenue increased $1.6 million, or 3%, primarily due to higher average monthly revenue per unit ("ARPU") related to price actions implemented in the prior year. The increases in commercial services were partially offset by a decrease in commercial broadband revenue.

Service – U.S. Government

Government service revenue grew 3% to $27.6 million in the second quarter, reflecting contractual rate increases in the Enhanced Mobile Satellite Services contract (the "EMSS Contract") over the prior year. The U.S. government continues to be Iridium's largest single customer, representing 17% of service revenue and nearly all of engineering services and support business.

Iridium continues to expect a renewal of its EMSS Contract with the U.S. Space Force by March 2027.

Equipment

Equipment revenue was $20.8 million in the second quarter, up 7% compared to $19.5 million in the prior-year quarter.

Engineering & Support

Engineering and support revenue was $43.1 million during the second quarter, up 3% compared to $41.9 million in the prior-year quarter, primarily due to increasing activity with the U.S. government.

Strategic Growth Initiatives

In February 2026, Iridium announced four strategic initiatives that are driving new activity with business partners and designed to drive revenue growth and business expansion into new industries and applications. The Company remains focused on investing in and expanding its presence through the following initiatives:

Satellite IoT. Iridium continues to make progress on both proprietary and standards-based products and services to expand its IoT offering with key target markets. The introduction of the Iridium 9604, a new tri-mode module launched on June 23, 2026, combines Iridium Short Burst Data^® (SBD^®) satellite connectivity, LTE-M cellular, and GNSS positioning in a power efficient, small form factor module. The integrated architecture provides operational and economic benefits that are engineered to simplify device design, reduce costs, and allow the Iridium 9604 to serve as a next-generation platform for satellite IoT services.

Iridium will also introduce its new standards-based service, Iridium NTN Direct, later this year. Live over-the-air demonstrations with mobile network operators, semiconductor companies, and existing business partners are underway to extend the reach of terrestrial services with satellite connectivity. These standardized services will provide direct-to-device (D2D) capabilities and support low-cost IoT applications, where reliability and coverage are critical, and even for connecting consumer devices from space.
Assured PNT. The recent announcement of the commercial availability of Iridium's new PNT ASIC, expands the potential applications and addressable market for Iridium's global PNT services. Designed to help protect GPS- and GNSS-dependent devices from growth jamming, spoofing, and other threats, Iridium PNT is used by commercial, civil, and government enterprises to ensure resilience for critical infrastructure, communications, and transportation.
National Security Missions. Iridium continues to build off its successful history of providing mission critical communications under the EMSS program to develop and deploy efficient and resilient operations supporting the U.S. Space Force. Leveraging its ongoing work developing ground systems and managing the operations centers for the Space Development Agency's Proliferated Warfighter Space Architecture (PWSA), Iridium is positioned to expand its strategic relationship with the U.S. government. As new requirements and demand for systems take shape, additional opportunities to leverage Iridium's expertise and capabilities for other national security initiatives continue to emerge.
Aviation Safety. Iridium's leadership position in aviation safety advanced further with the Company's acquisition of Aireon LLC, the world's only space-based Automatic Dependent Surveillance-Broadcast (ADS-B) air traffic surveillance system, on July 2, 2026. This acquisition of Aireon accelerates Iridium's growth into services for airlines and air navigation service providers, while adding valuable commercial data services capabilities and incremental revenue streams.

Iridium is actively developing new products that leverage Aireon's existing satellite-based aviation safety surveillance services and global high-fidelity data set to deliver greater value to the entire aviation industry. This acquisition is expected to result in at least an additional consolidated $100 million of service revenue and $30 million of OEBITDA on an annualized basis.

Capital Allocation

Capital expenditures were $21.8 million for the second quarter, including $1.6 million in capitalized interest. The Company ended the second quarter with gross Term Loan debt of $1.8 billion, and a cash and cash equivalents balance of $184.2 million, for a net debt balance of $1.6 billion. The Company ended the second quarter with net leverage of 3.3 times trailing twelve months OEBITDA.

Subsequent to the end of the second quarter, Iridium closed on its acquisition of Aireon LLC. The aggregate purchase price payable was approximately $366.7 million, of which 50% was paid in cash at the closing of the acquisition and the remaining 50% was deferred in the form of a $183.4 million loan from the sellers, bearing no interest, maturing one year following the closing. The Company drew down $100 million on its Revolving Facility as a source of cash paid at the closing. Additionally, Iridium assumed Aireon's existing credit facility with an aggregate principal balance of $154.7 million, with a scheduled maturity date of October 10, 2028.

Iridium paid its second quarter dividend of $0.15 per share of common stock on June 30, 2026, resulting in a total payment of $16.2 million to stockholders.

(1) Non-GAAP Financial Measures & Definitions

In addition to disclosing financial results that are determined in accordance with U.S. GAAP, the Company reports OEBITDA, which is a non-GAAP financial measure, as a supplemental measure to help investors evaluate the Company's fundamental operational performance. OEBITDA represents earnings before interest, income taxes, depreciation and amortization, gain (loss) on equity method investments, transaction related expenses, and share-based compensation expenses. The Company considers the loss on early extinguishment of debt to be financing-related costs associated with interest expense or amortization of financing fees, which by definition are excluded from OEBITDA. Management believes such charges are incidental to, but not reflective of, the Company's day-to-day operating performance. OEBITDA does not represent, and should not be considered, an alternative to U.S. GAAP measurements such as net income or loss. In addition, there is no standardized measurement of OEBITDA, and the Company's calculations thereof may not be comparable to similarly titled measures reported by other companies. The Company believes OEBITDA is a useful measure across time in evaluating its fundamental core operating performance. Management also uses OEBITDA to manage the business, including in preparing its annual operating budget, debt covenant compliance, financial projections and compensation plans. The Company believes that OEBITDA is also useful to investors because similar measures are frequently used by securities analysts, investors and other interested parties in their evaluation of companies in similar industries. As indicated, OEBITDA does not include interest expense on borrowed money, the payment of income taxes, amortization of the Company's definite-lived intangible assets, or depreciation expense on the Company's capital assets, which are necessary elements of the Company's operations. Since OEBITDA does not account for these and other expenses, its utility as a measure of the Company's operating performance has material limitations. Due to these limitations, the Company's management does not view OEBITDA in isolation, but also uses other measurements, such as net income, revenues and operating profit, to measure operating performance. Please refer to the schedule below for a reconciliation of consolidated GAAP net income to OEBITDA and Iridium's Investor Relations webpage at www.iridium.com for a discussion and reconciliation of this and other non-GAAP financial measures.
