3 risk signal(s), 1 positive signal(s), 1 watch item(s) detected from XBRL filing diff 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.

  • Free cash flow deteriorating: FCF declined +452.3% YoY (from $833.0M to $-2.94B). With OCF at $9.80B and capex at $12.74B, cash generation capacity is weakening — monitor for dividend/buyback sustainability.
  • NEW: Going concern doubt in latest filing: The term "going concern" "substantial doubt" 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 5 filing(s).
  • NEW: Restatement of financial statements in latest filing: The term "restatement of" "previously issued" 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 5 filing(s).
  • Operating cash flow exceeds net income: OCF is 2.26x net income, indicating high earnings quality — cash conversion is strong and accruals are not inflating reported profits.
  • NEW: Off-balance sheet arrangements: Off-balance sheet arrangements appears in recent filings but not in the prior 24-month period. Monitor for materiality.
  • 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.
  • 1 new XBRL disclosure(s) in latest filing — expanding reporting scope.
  • 20 disclosure(s) dropped from prior year — reduced reporting granularity.
  • 3 new risk-language term(s) detected in filing text: Going concern doubt, Restatement of financial statements, Off-balance sheet arrangements.
