Detected red flags (12)
- Free cash flow deteriorating: FCF declined +37.8% YoY (from $14.71B to $9.14B). With OCF at $13.01B and capex at $3.86B, cash generation capacity is weakening — monitor for dividend/buyback sustainability.
- 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.
- Operating cash flow exceeds net income: OCF is 35.63x net income, indicating high earnings quality — cash conversion is strong and accruals are not inflating reported profits.
