Listen to the news

Iridium Communications (IRDM) just caught a lift after being added to the S&P 600, a technical shift that sparked fresh buying from index-tracking funds and pushed the stock meaningfully higher.

See our latest analysis for Iridium Communications.

That index bump arrives after a tough stretch, with the share price sitting at $17.40 and a year-to-date share price return of minus 41.16%. The one-year total shareholder return of minus 37.92% shows longer term holders are still deep in the red, even as short term momentum has perked up with a 7-day share price return of 4.88% and a 30-day share price return of 6.62%. This suggests sentiment is stabilising rather than surging.

If Iridium’s move on index news has you wondering what else might be setting up for a turn, this is a good moment to explore fast growing stocks with high insider ownership.

With shares still down sharply over one and three years but trading at roughly a 30% discount to analyst targets, is Iridium an undervalued turnaround story, or is the market already pricing in all the future growth?

Most Popular Narrative: 41.5% Undervalued

With Iridium Communications last closing at $17.40 against a narrative fair value of $29.75, the story points to meaningful upside if assumptions hold.

The company's fully deployed next-gen constellation and declining capex profile are freeing up significant cash flow for buybacks and steady dividend increases, directly boosting per-share earnings potential and making Iridium's free cash flow yield structurally attractive.
