Duke Energy Corp. (DUK) 10-K Red Flags

Risk signals extracted deterministically from Duke Energy Corp.’s SEC 10-K/10-Q XBRL filings — no LLM, every finding cites the underlying data.

Detected red flags (16)

  • Free cash flow deteriorating: FCF declined +3629.2% YoY (from $48.0M to $-1.69B). With OCF at $12.33B and capex at $14.02B, cash generation capacity is weakening — monitor for dividend/buyback sustainability.
  • 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 2.48x net income, indicating high earnings quality — cash conversion is strong and accruals are not inflating reported profits.
  • NEW: Impairment charge: Impairment charge appears in recent filings but not in the prior 24-month period. Monitor for materiality.
  • NEW: Restructuring: Restructuring appears in recent filings but not in the prior 24-month period. Monitor for materiality.
  • 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.
