years 1–5, then moving to 8.9% (mature company)

AT&T's revenue grew 2.6% over the last twelve months and 1.3% a year over three years. Today's price of $25.46 implies 8.8% revenue growth in year 1, fading to 4.8% by year 10, at an operating margin of 20.1%.

Our base case continues the trend (2.0%, fading), moves the operating margin from 21.0% to 20.1% by year 5 and reinvests $1.61 of capital for each additional dollar of revenue. Discounted at 5.9%, that gives a base-case model value of $20.63 per share (bear $10.42, bull $35.55); the price is 23% above the base case.

How we got this number

1Historical base from the filingsReported fact

All figures come from the XBRL data in the company's SEC filings (10-K, 10-Q), in US dollars. "TTM" = trailing twelve months. EBITA = operating income before amortisation of acquired intangibles and before expensed acquired R&D – both consequences of past acquisitions, which the model does not extrapolate.

Operating invested capital = equity + financial debt incl. leases − cash − goodwill − acquired intangibles − equity-method stakes: the capital that organic growth actually ties up. ROIC = EBITA × (1 − tax rate) / operating capital (TTM column: incl. lease interest, latest balance sheet). TTM revenue = FY ending 2025-12-31 ($126B) + year-to-date to 2026-06-30 ($63.1B) − prior-year period ($61.5B).

2Cost of equity (CAPM)Market dataAssumption

kE = rf + β × ERP = 4.79% + 0.64 × 4.14% = 7.45%
  • rf 4.79% – 10-year US Treasury yield on Sep 1, 2026, the date of the equity risk premium estimate (the two must match; today: 5.18% on Sep 24, 2026) (U.S. Treasury).
  • ERP 4.14% – implied equity risk premium of the S&P 500 by Aswath Damodaran as of Sep 1, 2026 (NYU Stern). It is backed out of current index prices and expected cash flows, not historical averages.
  • β 0.64 – bottom-up beta: the "Telecom. Services" industry (39 US firms, Damodaran, January 2026) has a cash-corrected unlevered beta of 0.38. Relevered with AT&T's leverage (debt incl. leases / market value = 92.1%):
    β = βU × (1 + (1 − t) × D/E) = 0.38 × (1 + 0.75 × 0.921) = 0.64
  • In the mature state (from year 10) we set β = 1: kE = 4.79% + 4.14% = 8.93%, the market's expected return. In years 6–10 the cost of capital moves there linearly.

3Cost of debtReported factAssumption

Interest coverage = EBIT / interest expense (TTM) = $25.6B / $7.19B = 3.6x. In Damodaran's table for large non-financial firms (January 2026) this maps to a synthetic rating of A3/A- with a 0.89% default spread.

kD = (rf + spread) × (1 − t) = (4.79% + 0.89%) × (1 − 25%) = 4.26%

Tax rate 25%: 21% federal plus about 4% state taxes (marginal rate).

4Weighted average cost of capital (WACC)Market dataModel output

WACC = E/(D+E) × kE + D/(D+E) × kD = 52.1% × 7.45% + 47.9% × 4.26% = 5.92%

E = market value $177B (Sep 24, 2026); D = financial debt incl. lease liabilities $163B (book value as a proxy). This WACC applies to years 1–5; by year 10 it moves to 8.93%, the cost of capital of an average mature company (rf + ERP) – the rate at which Damodaran's implied premium discounts the market beyond year 5.

5Forecast and discounted cash flowsAssumptionModel output
