Detected red flags (14)
- Free cash flow deteriorating: FCF declined +39.7% YoY (from $8.12B to $4.90B). With OCF at $7.11B and capex at $2.21B, cash generation capacity is weakening — monitor for dividend/buyback sustainability.
- NEW: Going concern doubt in latest filing: The term "going concern" appears in recent 10-K/10-Q filings but was NOT present in the prior 24-month period. This is a new risk disclosure that warrants attention. Found in 14 filing(s).
- Material weakness in internal controls: The term "material weakness" appears in 20 recent filing(s) (vs 2 in the prior period). This risk language is ongoing.
- NEW: Substantial doubt about ability to continue in latest filing: The term "substantial doubt" "ability to continue" appears in recent 10-K/10-Q filings but was NOT present in the prior 24-month period. This is a new risk disclosure that warrants attention. Found in 10 filing(s).
- NEW: Restatement of financial statements in latest filing: The term "restate" "financial statements" appears in recent 10-K/10-Q filings but was NOT present in the prior 24-month period. This is a new risk disclosure that warrants attention. Found in 3 filing(s).
- Operating cash flow exceeds net income: OCF is 1.57x net income, indicating high earnings quality — cash conversion is strong and accruals are not inflating reported profits.
- Endogenous analysis: Free cash flow declined despite stable or rising capex, indicating the cash burn is operational rather than investment-driven. This is a structural concern — cost reduction or asset sales may be needed to restore FCF.
- Endogenous analysis: The combination of explicit "going concern" language in the filing with deteriorating cash flow or rising leverage is a severe warning signal — the company's own auditors have flagged doubt about the ability to continue as a going concern.
- 2 new XBRL disclosure(s) in latest filing — expanding reporting scope.
- 20 disclosure(s) dropped from prior year — reduced reporting granularity.
