A wonderful business — priced for growth it hasn't delivered.
A great company, but no margin of safety at this price. Worth watching, not worth buying here.
Price against fair value
Free cash flow — 5-year history ($B)
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.
The read — lights & verdict
- OvervaluedFair value ~$283 vs $477 — trading 41% above what the math supports.
- Price assumes a big accelerationYou'd need ~13%/yr free-cash-flow growth to justify today's price; it has done -6.6%/yr lately.
- Revenue still growingUp 8.9% last year — demand isn't the problem.
- Cash flow flat-to-downFree cash flow ~-6.6%/yr — big, but not compounding. The crux for a value buyer.
- Fortress balance sheetNet cash positive (+$12B) — little solvency risk.
How this was built. Every figure is computed from Vertex Pharmaceuticals Incorporated'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 $477.36 taken 2026-07-24 (founder-supplied CSV, July 2026) — it is not live and does not move during the day.
