Frequently Asked Questions

Is AMT stock undervalued or overvalued?
🟢 UNDERVALUED

AMT trades at $181.55 vs. our DCF-derived intrinsic value of $206.81, implying +18% upside. At a 9.5% WACC and 20.0% projected FCF growth, the market appears to be underpricing the present value of AMT's future cash flows. The bear case ($101.31) still suggests upside, providing margin of safety.

What is AMT's intrinsic value?

Using a 5-year DCF model: Base FCF of $4.38B, projected at 20.0% 5Y CAGR (best of revenue, EPS, or FCF growth), discounted at 9.5% WACC, with 3.0% terminal growth. Terminal value calculated via Gordon Growth Model: TV = FCF₅ × (1+g) / (WACC−g). After deducting $41.95B net debt and dividing by 0.47B shares: Bear $101.31 | Base $206.81 | Bull $367.09. Current price $181.55 implies +18% to base case.

How is AMT's fair value calculated?

DCF Methodology:

① Project FCF years 1-5 using 20.0% growth derived from 5-year historical CAGR (best of revenue, EPS, or FCF growth, with 8% floor and 25% cap).

② Calculate terminal value at year 5 using perpetuity growth model with g=3.0%.

③ Discount all cash flows to PV using WACC=9.5%.

④ Sum PV of explicit period + PV of terminal value = Enterprise Value ($138.77B).

⑤ Subtract net debt, divide by shares outstanding.

Sensitivity analysis available above—adjust WACC ±2% or growth ±3% to stress-test the valuation. Implied EV/FCF multiple: 31.7x.
