Iridium runs a network of satellites that lets people and machines stay connected almost anywhere on Earth, even where cell phones have no signal.
Iridium Communications is a satellite company that keeps people and machines connected where ordinary cellular networks can't reach. Its customers include ship crews, pilots, soldiers, emergency responders, and mining and energy workers who travel to the world's most remote places. Some also use its satellites to track cargo, monitor pipelines, and send short data bursts from machines.
The core of the business is something called the Iridium constellation: a group of satellites in low orbit around the Earth, linked to each other so the signal can hop across the network and come down anywhere. It was a hard engineering problem that originally failed as a consumer phone company and went bankrupt in 1999. It was rescued, rebuilt, and now serves largely professional customers rather than everyday consumers. A major upgrade finished in 2019, replacing the old satellites with stronger ones; the company also sells internet access to aircraft and other vehicles. Iridium's biggest strength is that it built its own private network and owns the whole system now, from the satellites to the radio spectrum. Its main rivals are higher-orbit satellite phone companies and new satellite internet constellations. Its annual revenue is roughly in the high hundreds of millions of dollars, and it has grown steadily as demand rises for connectivity at sea, in the air, and for industrial devices. What makes Iridium unusual is that it is a capital-intensive infrastructure business with recurring subscription-type service revenue. Customers pay for monthly plans and equipment, which gives it predictable cash flow. That cash has funded new services, debt reduction, and share buybacks. It is not a fast-growth tech company; it's more like a toll road in the sky, collecting steady fees from people for whom "no signal" is not an option.
