The 10-K Deep Dive: Five Numbers That Tell the Whole Story
The executive summary of a 10-K is written by management to emphasize what they want you to remember. The five numbers that reveal the actual health of the business are buried three layers deep — in the financial statements, the footnotes, and the MD&A. Here's exactly where to find them.
Why the executive summary misleads
Management teams are not required to highlight negative trends in the letter to shareholders — they are required to disclose them, but disclosure can be buried in footnotes. Stonkly's filings score flags language changes in risk factors and MD&A between consecutive annual filings, which is often where early warning signs surface months before they appear in the financial statements.
The five numbers
These five data points reveal what the headline figures don't. Each one requires navigating past the top-level financial statements into the notes and schedules where the detail lives.
- Free Cash Flow: operating cash flow minus capex. If FCF is falling while reported earnings rise, something is being managed
- Days Sales Outstanding: in the receivables footnote. Rising DSO means revenue is being recognized before cash is collected
- Debt maturity schedule: in the long-term debt notes. Identifies cliff risk — large maturities in 12–24 months requiring refinancing
- Effective tax rate: in the income tax footnote. Unexplained rate drops often indicate one-time items inflating reported EPS
- Segment profitability: in the segment footnote. Consolidated margin can hide a core business in decline behind a growing division
Where to find them in the filing
The 10-K has a consistent structure across all public companies. Knowing where each data point lives saves the time most investors spend scanning the wrong sections.
- FCF: Consolidated Statements of Cash Flows, pages 50–70 of most filings
- DSO: Note on Accounts Receivable, typically notes 3–5
- Debt maturity: Note on Long-Term Debt, typically notes 8–12
- Effective tax rate: Note on Income Taxes
- Segment data: Note on Segment Information, near the end of the notes
What Stonkly's AI is reacting to
The AI filings score runs language-change detection across consecutive 10-K filings. Additions to risk factors, revisions to revenue recognition policy descriptions, and new related-party disclosures all trigger score adjustments. A drop in the filings score often precedes an earnings miss by one to two quarters — the language changes before the numbers do.
Key Takeaway
You don't need to read the entire 10-K. Navigate directly to these five data points, build a quick year-over-year comparison, and the trend will tell you more than the narrative. The filing score in Stonkly is doing this work continuously — when it drops, go read the notes.
