What happened

Shares of Iridium Communications (IRDM 1.88%) were up 9% on Tuesday. The satellite communications company -- the first to offer internet and voice service that covers 100% of the globe -- reported better-than-expected second-quarter 2021 earnings and a solid outlook for the remainder of the year.  

So what

Iridium reported a total revenue increase of 7% in the second quarter to $150 million, driven by a 7% increase in services (subscriptions to its global voice and data service) to $121 million. As a result, net income swung positive to $3.8 million, compared to a net loss of $12.3 million for the same period in 2020.

The communications company finished work on its next-gen satellite constellation, Iridium Next, in early 2019 -- having tapped services from SpaceX to get its hardware into low-Earth orbit. With a high rate of expenses now in the rearview mirror and broadband internet service now available for businesses and government organizations, the company is enjoying steady subscriber growth and fast-improving profitability. Its billable subscriber count was 1.62 million at the end of the second quarter, compared to 1.36 million last year.  

Now what

Given the strong showing in the spring, management took the opportunity to raise its 2021 outlook. It's now calling for full-year growth in service revenue of 4% to 5% (previously pegged at about 3%), and operational EBITDA growth of about 3% to 6%.

In February, the board of directors approved a $300 million share repurchase plan now that the new satellites are generating positive free cash flow. It expects this $300 million repurchase will be complete by the end of 2022 and will substantially reduce Iridium's operational EBITDA-to-debt leverage.

And that's the main metric to keep an eye on here. Though new satellite internet competition (like SpaceX's Starlink) is looming, Iridium is a stable business with subscribers primarily made up of government entities. Total debt was $1.63 billion as of the end of June, but was slightly offset with cash and equivalents of $219 million. With profits on the rise with greater use of Iridium's satellites, this should remain one of the more stable companies in the burgeoning space economy.
