In 2025, the latest annual-report year available in the research, Iridium reported $871.7 million in total revenue. Revenue categories were commercial services ($525.9 million, about 60%), government services ($108.0 million, about 13%), subscriber equipment ($81.1 million, about 9%), and engineering and support services ($156.6 million, about 18%). These are revenue categories rather than a breakdown by individual product.[5] [7]+18

Geographic presence

Iridium Communications operates a satellite network with global, pole-to-pole coverage, including remote land areas, open oceans, airways and polar regions. Its network comprises 66 operational satellites linked to support coverage in areas with limited terrestrial networks.[25]+2

Its principal executive offices are in McLean, Virginia. Listed facilities include sites in McLean, Reston and Leesburg, Virginia; Chandler and Tempe, Arizona; Fairbanks, Alaska; and Svalbard, Norway, Izhevsk, Russia, and Punta Arenas, Chile. The filings do not give employee counts by location.[28][29] Iridium does not report revenue by country or region in the reviewed filings; it does report that the U.S. government accounted for 29% of 2025 revenue.[30] [25]+6

Business segments

Iridium Communications reports **one business and reportable segment**, covering satellite communications services and products. The company’s chief operating decision maker assesses performance and allocates resources on a consolidated basis, so its commercial and government markets and its revenue categories are not separately reported accounting segments. The sole segment therefore represents 100% of reported revenue; FY2025 consolidated revenue was $871.7 million.[31]+2

The company identifies land mobile, maritime, aviation, IoT, hosted payloads and other data services (including PNT), and U.S. government as principal business verticals. FY2025 commercial service revenue was $525.9 million, about 60.3% of consolidated revenue. Within that, voice and data contributed $232.2 million (26.6% of total revenue), IoT data $181.4 million (20.8%), broadband $50.7 million (5.8%), and hosted payload and other data $61.6 million (7.1%). These are revenue-category breakdowns, not separate segments.[34][35] U.S. government revenue was approximately 29% of FY2025 total revenue, a customer-market measure rather than a segment disclosure.[30] [31]+9

Company history

Iridium’s origins date to 1987, when Motorola engineers Bary Bertiger, Ray Leopold and Ken Peterson developed the concept for a global satellite communications network. Motorola incorporated Iridium as a separate company in 1991. The first-generation satellite constellation became operational in 1998, and commercial service began on November 1 that year. After the original business entered bankruptcy in 1999, investors acquired its satellite assets and service resumed in 2001.[36]+4

In 2009, Iridium Communications Inc. became a publicly traded company following the close of its transaction with GHL Acquisition, and its shares began trading on Nasdaq under the symbol IRDM. Iridium formed Aireon in 2011 to develop aircraft surveillance using payloads hosted on its satellites. From 2017 to 2019, the company deployed its Iridium NEXT constellation; it declared the 66-satellite system complete in February 2019. Iridium Certus broadband service launched in January 2019, among the first commercial capabilities enabled by NEXT.[40]+5 [41]+10
