⚠ Investor warnings · 5 flags
- severeNegative equity, extreme leverageDebt/Equity of -25.48 signals deeply negative book equity, indicating liabilities massively exceed assets - a structurally distressed balance sheet.
- highDeeply negative free cash flowFCF is -$931.6M, meaning IRM consumes significant cash despite revenue growth, relying on external financing to fund operations and dividends.
- highSuspicious ACCE score spikeScore jumped +61 points in 90 days (from 5 to 66), an unusually sharp reversal that warrants scrutiny of data quality or one-time distortions.
- moderateElevated valuation, thin marginsP/E of 133x and net margin of only 3.8% leave virtually no earnings cushion; any revenue softness could eliminate profitability entirely.
- moderateInsider selling, zero buyingInsiders sold $12.64M with $0 in purchases over the last 10 disclosures, signaling no insider conviction at current price levels.
