What the math is really telling you. Watch whether cash flow is compounding — that, more than any single year, is what a value read hangs on.

  • Warning:
    Overvalued
    Fair value ~$140 vs $226 — trading 38% above what the math supports.
  • Caution:
    Price assumes a modest step-up
    Priced for ~11%/yr vs a 8.0%/yr record — a stretch, not heroic.
  • Good:
    Revenue still growing
    Up 5.8% last year — demand isn't the problem.
  • Good:
    Cash flow compounding
    Free cash flow up ~8.0%/yr — the engine is growing.
  • Caution:
    Manageable net debt
    Net debt of $1B — about 2.0× annual free cash flow. Normal for a mature company.

Where this number comes from →

How this was built. Every figure is computed from IDEX Corporation's SEC filings — no estimates, no AI. Two-stage DCF: 9% discount rate, 5% free-cash-flow growth for 10 years, 2.5% terminal. Free cash flow is operating cash flow less capital spending. Net cash is cash and marketable securities less borrowings, commercial paper and finance leases; operating leases are disclosed but never counted as debt. Fundamentals are from the FY25 annual report and change only when a new one is filed. Price of $225.79 taken 2026-09-08 (Google Finance, manual entry, 2026-09-08) — it is not live and does not move during the day.
