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

Detected red flags (14)

  • Leverage is building — debt rising while equity contracts: Long-term debt grew +139.6% while stockholders equity declined -3.6%. The debt-to-equity ratio is deteriorating, increasing financial risk and interest burden. This may constrain future borrowing capacity.
  • Going concern doubt: The term "going concern" appears in 3 recent filing(s) (vs 1 in the prior period). This risk language is ongoing.
  • Material weakness in internal controls: The term "material weakness" appears in 18 recent filing(s) (vs 2 in the prior period). This risk language is ongoing.
  • Restatement of financial statements: The term "restate" "financial statements" appears in 11 recent filing(s) (vs 1 in the prior period). This risk language is ongoing.
  • Operating cash flow exceeds net income: OCF is 1.58x net income, indicating high earnings quality — cash conversion is strong and accruals are not inflating reported profits.
  • Gross margin expansion: Gross margin expanded +4.2%pp (from 68.4% to 72.6%), indicating improved pricing power, cost efficiency, or favorable product mix.
  • 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.
  • 4 new XBRL disclosure(s) in latest filing — expanding reporting scope.
  • 20 disclosure(s) dropped from prior year — reduced reporting granularity.
