IRDMIridium Communications Inc.
Is it safe?
Forensics clean, with a caveat: a safe balance sheet and comfortable debt (AA), but big price swings.
Financially healthy, low distress risk Altman Z-score, a bankruptcy-risk model from five balance-sheet ratios.
Insiders were net sellers (-$19.6M, 90 days to Oct 8, 2026), selling is often routine.
Net cash and profitable. A rule of thumb on leverage, not a credit rating.
Large price swings, high volatility. Worst drawdown -75% · now 9% below its 52-week high.
Unless marked, from SEC EDGAR, as of Dec 31, 2025.
Against the whole market›
Percentile against every name Ryufin tracks. Higher is better; the tick marks the middle of the market. Context, not one of the checks above.
Where this answer is blind. Altman sits structurally low for utilities and pipelines; Beneish runs high for fast growers, since sales growth alone lifts it; banks and REITs are excluded.
Can IRDM take a bad year?
Iridium Communications Inc. holds $172M more cash than debt, so a bad year is a question about profits, not about lenders.
