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 ~$35 vs $26 — a margin of safety of 37%.
- Good:Price is in line with its recordPriced for ~2%/yr, roughly what it has delivered (6.3%/yr).
- Good:Revenue still growingUp 2.7% last year — demand isn't the problem.
- Good:Cash flow compoundingFree cash flow up ~6.3%/yr — the engine is growing.
- Warning:Heavy debt loadNet debt of $117B — roughly 6× annual free cash flow. This changes the risk picture. It also has $23B of operating-lease commitments — about 1.2× annual free cash flow — which this figure does not count as debt.
How this was built. Every figure is computed from AT&T Inc.'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. We subtract net debt from the value of the business — for AT&T that is about $117B, or $16 per share. Fundamentals are from the FY25 annual report and change only when a new one is filed. Price of $25.68 taken 2026-09-04 (Google Finance, manual entry, 2026-08-28) — it is not live and does not move during the day.
