Iridium Announces Second Quarter 2025 Results; Updates Full-Year Outlook
MCLEAN, Va. – July 24, 2025 – Iridium Communications Inc. (Nasdaq:IRDM) (“Iridium”), a leading provider of global voice and data satellite communications, today reported financial results for the second quarter of 2025 and updated its full-year 2025 outlook. Net income was $22.0 million, or $0.20 per diluted share, for the second quarter of 2025, as compared to net income of $32.3 million, or $0.27 per diluted share, for the second quarter of 2024. The decrease in net income was primarily the result of a one-time $19.8 million gain related to the acquisition of Satelles, Inc. recognized in the second quarter of 2024, which did not reoccur in 2025. Operational EBITDA (“OEBITDA”)(1) for the second quarter was $121.3 million, as compared to $114.0 million for the prior-year period, representing a year-over-year increase of 6%.
Iridium reported second quarter total revenue of $216.9 million, which consisted of $155.6 million of service revenue and $61.3 million of revenue related to equipment sales and engineering and support projects. Total revenue increased 8% versus the comparable period of 2024. Service revenue, which represents primarily recurring revenue from Iridium’s growing subscriber base, grew 2% from the year-ago period and was 72% of total revenue for the second quarter of 2025.
The Company ended the quarter with 2,483,000 total billable subscribers, which is up from 2,413,000 for the year-ago period and compares to 2,443,000 for the quarter ended March 31, 2025. Total billable subscribers grew 3% year-over-year, led by growth in commercial IoT.
“We’re making great progress on our direct-to-device service with testing now underway and are also finding exciting, innovative applications for our new PNT service,” said Matt Desch, CEO, Iridium. Desch added, “I'm pleased that the Board approved an increase to our September quarterly dividend. This 5% increase for the full year demonstrates our confidence in Iridium’s long-term prospects and continued growth.”
Iridium 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. The Company’s commercial customer base is diverse and includes markets such as maritime, aviation, oil and gas, mining, recreation, forestry,
construction, transportation and emergency services. These customers rely on Iridium’s products and services as critical to their daily operations and integral to their communications and business infrastructure.
•Commercial service revenue was $128.8 million, up 2% from last year’s comparable period.
•Commercial voice and data: Revenue was $56.8 million, up 1% from the year-ago period, and subscribers remained consistent with the year-ago period at 415,000. Average revenue per user (“ARPU”) was $46 during the second quarter, unchanged from last year’s comparable period.
•Commercial IoT data: Revenue was $44.8 million, up 8% from the year-ago period, driven by a 5% growth in subscribers from the year-ago period to 1,924,000, and an increase in a contract with a large customer. ARPU was $7.83 in the second quarter, compared to $7.70 in last year’s comparable period.
•Commercial broadband: Revenue was $12.7 million, down 6% from $13.5 million in the year-ago period, and subscribers declined 3% from the year-ago period to 16,300. ARPU was $260 during the second quarter, compared to $269 in last year’s comparable period, reflecting the increased prevalence of Iridium’s use as a companion service.
•Hosted payload and other data service: Revenue was $14.5 million, up 1% from $14.4 million in the year-ago period. The year-over-year change primarily reflected contributions from Iridium’s PNT service partially offset by other data service contracts.
•Iridium’s commercial business ended the quarter with 2,355,000 billable subscribers, which compares to 2,271,000 for the prior-year quarter and 2,310,000 for the quarter ended March 31, 2025. IoT data subscribers represented 82% of billable commercial subscribers at the end of the quarter, an increase from 81% at the end of the prior-year period.
Service – U.S. Government
Iridium’s voice and data solutions improve situational awareness for military personnel and track critical assets in tough environments around the globe, providing a unique value proposition that is not easily duplicated.
Under Iridium’s Enhanced Mobile Satellite Services contract (the “EMSS Contract”), a seven-year, $738.5 million fixed-price airtime contract with the U.S. Space Force signed in September 2019, Iridium provides specified satellite airtime services for an unlimited number of Department of Defense and other federal government subscribers. Iridium also provides maintenance and support work for the U.S. government’s dedicated Iridium® gateway under two other contracts with the U.S. Space Force. Iridium Certus® airtime services are not included under these contracts and may be procured separately for an additional fee.
•Government service revenue grew 1% to $26.8 million in the second quarter, reflecting a contractual rate increase in the EMSS Contract as of September 2024.
•Iridium’s U.S. government business ended the quarter with 128,000 subscribers, which compares to 142,000 for the prior-year quarter and 133,000 for the quarter ended March 31, 2025. Government voice and data subscribers decreased 22% from the year-ago period to 49,000 as of June 30, 2025. Government IoT data subscribers remained flat year-over-year and represented 62% of government subscribers at the quarter end.
•Under the terms of the multi-year EMSS Contract, Iridium’s fixed-price rate will increase to $110.5 million for the contract year beginning September 15, 2025.
Equipment
•Equipment revenue was $19.5 million in the second quarter, down 15% compared to $22.8 million in the prior-year quarter.
•For the full-year 2025, the Company expects equipment sales to be in line with 2024.
Engineering & Support
•Engineering and support revenue was $41.9 million during the second quarter, up 62% compared to $25.8 million in the prior-year quarter, primarily due to increasing activity with the U.S. government.
•For the full-year 2025, the Company expects engineering and support revenue to increase from 2024.
Capital expenditures were $20.7 million for the second quarter, including $0.9 million in capitalized interest. The Company ended the second quarter with gross Term Loan debt of $1.8 billion, $50.0 million outstanding under the Revolving Facility, and a cash and cash equivalents balance of $79.3 million. The Company ended the second quarter with net leverage of 3.6 times trailing twelve months OEBITDA.
Iridium paid its second quarter dividend of $0.14 per common share on June 30, 2025. The Company’s Board of Directors declared a quarterly dividend of $0.15 per share for the third quarter 2025, which represents a full-year dividend increase of 5.5%. Iridium has increased the dividend paid per share each year since initiating its dividend in 2023.
During the quarter, the Company repurchased approximately 2.6 million shares of its common stock under its previously announced share repurchase program at a total purchase price of $65.0 million. As of June 30, 2025, $295.3 million remained available and authorized for repurchase under this program through December 31, 2027. The Company has retired 34.8 million shares, for an aggregate purchase price of $1.2 billion, since its share repurchase program commenced in February 2021.
2025 and Longer-Term Outlook
The Company updated its full-year 2025 outlook for service revenue growth and maintained its full-year 2025 OEBITDA and long-term guidance as follows:
•Total service revenue growth between 3% and 5% for full-year 2025. (Previously, guidance for total service revenue growth was between 5% and 7% for full-year 2025). Total service revenue for 2024 was $614.9 million.
•Full-year 2025 OEBITDA between $490 million and $500 million. OEBITDA for 2024 was $470.6 million.
•Cash taxes of less than $10 million per year through 2026. We expect that the longer-term cash tax rate will move closer to the statutory rate in 2028.
•Net leverage below 4.0 times OEBITDA through 2026 and falling below 2.0 times OEBITDA by the end of the decade, assuming ongoing execution of the Company’s share repurchase
authorization and the payment of expected quarterly dividends. Net leverage was 3.6 times OEBITDA at December 31, 2024.
(1)Non-GAAP Financial Measures & Definitions
In addition to disclosing financial results that are determined in accordance with U.S. GAAP, the Company reports Operational EBITDA, which is a non-GAAP financial measure, as a supplemental measure to help investors evaluate the Company’s fundamental operational performance. Operational EBITDA represents earnings before interest, income taxes, depreciation and amortization, gain (loss) on equity method investments, acquisition and related costs, 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 Operational EBITDA. Management believes such charges are incidental to, but not reflective of, the Company’s day-to-day operating performance. Operational EBITDA 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 Operational EBITDA, and the Company’s calculations thereof may not be comparable to similarly titled measures reported by other companies. The Company believes Operational EBITDA is a useful measure across time in evaluating its fundamental core operating performance. Management also uses Operational EBITDA to manage the business, including in preparing its annual operating budget, debt covenant compliance, financial projections and compensation plans. The Company believes that Operational EBITDA 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, Operational EBITDA 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 Operational EBITDA 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 Operational EBITDA 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 Operational EBITDA and Iridium’s Investor Relations webpage at www.iridium.com for a discussion and reconciliation of this and other non-GAAP financial measures. The Company does not provide a forward-looking reconciliation of expected full year 2025 Operational EBITDA guidance as the amount and significance of certain items such as share-based compensation, acquisition related costs and gain/loss on equity method investments, that are required to develop meaningful comparable GAAP financial measures cannot be estimated at this time without unreasonable efforts.
