Company overview

Company snapshot

Iridium provides mobile voice and data satellite communications, broadband, IoT services, and specialized hardware for commercial, government, and consumer markets.

It operates a wholesale distribution model, generating revenue from service providers, value-added resellers, and manufacturers who deliver Iridium's connectivity solutions to end users.

The company serves businesses, U.S. and international government agencies, non-governmental organizations, and maritime and aviation sectors worldwide.

Iridium Communications delivers mission-critical satellite communications services globally, leveraging a robust network and diverse product suite. The company’s strategy centers on providing reliable connectivity in remote and challenging environments, supporting enterprise, government, and IoT applications. Its competitive edge is underpinned by a resilient satellite infrastructure and a broad portfolio of value-added solutions for demanding markets.

Foolish take

This Paris-based investment firm seems to have given up hope on Iridium's long-running turnaround story. As of October 7, the stock is down 38% in the last quarter and 71% from its three-year peak. Iridium trades at the modest valuation of 19 times trailing earnings and 2.4 times sales, but it's also affordable for good reason.

The satellite-based communications market is getting crowded, and Iridium can't match the top-grade radio spectrum portfolio that recently landed a $17 billion license deal for arch-rival EchoStar (NASDAQ:SATS). Of course, that deal was signed at the very end of the third quarter and probably wasn't the reason for Graphene's retreat. I'd just be surprised to see this firm picking up Iridium stock again, under these conditions.

Graphene's Iridium investment was also very short-lived. The reported position of 115,300 shares in the second quarter was the only time Graphene held any shares of this stock in the last two years. It's not surprising to see the firm exit this experimental investment quickly, given Iridium's disappointing earnings report in July.
