Cheap — but check the trap first.
It looks undervalued, but something is deteriorating. Cheap for a reason, or a real bargain?
Price against fair value
Free cash flow — 10-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
- Good:UndervaluedFair value ~$59 vs $22 — a margin of safety of 166%.
- Good:Price is in line with its recordPriced for ~-3%/yr, roughly what it has delivered (11.5%/yr).
- Warning:Revenue shrinkingDown 0.0% last year — cheap may mean broken.
- Good:Cash flow compoundingFree cash flow up ~11.5%/yr — the engine is growing.
- Warning:Heavy debt loadNet debt of $89B — roughly 6× annual free cash flow. This changes the risk picture.
How this was built. Every figure is computed from Comcast 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. Fair value is based on typical free cash flow over the last five years ($16.3B), not the latest year ($21.9B), which sat 35% above the company's own norm. Net cash is cash and marketable securities less borrowings, commercial paper and finance leases; operating leases are disclosed but never counted as debt. We subtract net debt from the value of the business — for Comcast that is about $89B, or $24 per share. Fundamentals are from the FY25 annual report and change only when a new one is filed. Price of $22.30 taken 2026-07-24 (founder-supplied CSV, July 2026) — it is not live and does not move during the day.
