American Tower Corporation (AMT)
Real estate — REIT de infraestructura de comunicaciones y centros de datos
American Tower is the largest independent owner of communications tower infrastructure at global scale (149,686 sites across 20+ countries) and operates 30 data centers, with long-term lease rental income (five to ten years, with escalations of ~3% annually in the U.S. or indexed to inflation in other markets) that sustains over US$54 billion in future non-cancellable revenue. The business combines a broad and stable moat—high renewal rates (churn ~2%), low incremental cost per additional tenant, and regulatory barriers to new infrastructure construction—with customer concentration, leverage of ~5.6x adjusted EBITDA (with narrow headroom against the leverage covenant), and unhedged currency exposure in its international operations. After declining ~20% from its 52-week high, it trades at 16×x AFFO per share, in a Fairly valued zone, with a dividend yielding 4.0% that contributes a stable portion of the total expected return over five years (+9%).

The essentials
- Global leader in communications tower infrastructure (149,686 sites in 20+ countries) and data centers (30 facilities, ~3.7 million net rentable square feet), with over US$54 billion in future non-cancellable contractual revenue and tenant churn of just ~2% of lease billings.
- Material customer concentration—T-Mobile, AT&T, Verizon Wireless, and Telefónica together represented ~59% of consolidated 2025 revenue—combined with leverage of ~US$37.4 billion (5.6x adjusted EBITDA) and just ~US$0.9bn of EBITDA cushion before breaching the 6.00x leverage covenant.
- Trades at 16×x AFFO per share; the latest declared distribution was US$1.70 per share (run-rate US$6.80/share/year), with a dividend yield of 4.0% that contributes a stable portion of total return.
Intrinsic value — two valuation methods
Total return at 5 years: 9.1%/year = 4.9% appreciation + 4.2% dividend. The target price ($226) is ex-dividend; the $42 in dividends collected over 5 years are added separately.
By both methods, the value today (DCF $305 · Multiples $218) exceeds the market price ($178).
Pillars of the analysis
The verdict — today vs 5 years
Today — fairly valued: at $178 trades ~18.1% below its value discounted to today (~$218); the discount is positive but does not reach the margin of safety we require (≥38%).
At 5 years — En valor: the target price ($226) plus dividends yield between the 4% floor and the 10% average return — a reasonable return, though without the margin of a great investment.
The bridge: the return at 5 years exceeds the risk-free rate (4.5%) — but the discount does not reach the required margin of safety (≥38%). To require a 15% annual return, it would need to be bought at ~$140.
Thesis
The business
Quality communications infrastructure with long-term contractual rent, periodic escalations, and low churn (~2%). The moat is broad and stable: high renewal rates, regulatory barriers to new infrastructure construction, and high operating leverage from the low incremental cost of adding tenants. Customer concentration and financial leverage (~5.6x adjusted EBITDA, with narrow headroom against the leverage covenant) are the primary risk sources, not indicators of underlying business erosion.
The valuation
Valued by AFFO per share, the standard metric for a REIT (§4), applying a terminal exit multiple within the infrastructure real estate band (~15-20x). AFFO per share grows with the revenue trajectory—contractual, decelerating smoothly from the recent historical high toward a mature infrastructure growth rate—and the exit multiple stays near current levels, without betting on expansion. Base value at five years is $226 per share, versus $178 today.
The margin of safety
At market price, the total estimated return over five years (appreciation plus growing dividend) is +9%, placing the stock in Fairly valued. The margin of safety versus the maximum price to pay for a 15% annual return target is -27%. The dividend, yielding 4.0% today and growing 4.9% between FY2024 and FY2025, provides a stable portion of total return.
What to monitor
The core disconfirmer is financial leverage combined with sensitivity to rates staying higher for longer: consolidated debt of ~US$37.4 billion (5.6x adjusted EBITDA) leaves just ~US$0.9bn of EBITDA cushion before breaching the 6.00x covenant—narrower headroom than the ratio in isolation suggests. Also watch the resolution of the AT&T Mexico dispute (~US$300 million annual revenue in arbitration, hearing scheduled for August 2026) and DISH Wireless default (2% of total revenue and 4% of U.S. & Canada revenue since January 2026), as well as currency impact on international operations—FX losses of US$809.4 million in 2025 versus gains of US$308.3 million in 2024, in a company that does not materially hedge that exposure outside a recent US$5.461.6 million euro-denominated debt hedge.
