SBA Communications (SBAC)
REIT de infraestructura de comunicaciones
SBA Communications operates 46,328 wireless communications towers in the United States and eleven countries across South America, Central America, and Africa, leasing space to the three major mobile carriers under 5- to 15-year contracts with fixed or inflation-indexed escalators. The moat combines control of the underlying ground position — 71% of towers on land owned or controlled for more than 20 years — with high switching costs for tenants and available structural capacity to add tenants at low incremental cost. 2026 is a transition year due to already-quantified churn from Sprint and EchoStar, which the company's own guidance leaves nearly flat; It trades close to intrinsic value, far from the required margin of safety.

The essentials
- 46,328 towers at year-end 2025 (72.6% of domestic site-leasing revenue in the United States, the rest in Brazil, Guatemala, and nine other markets across South America, Central America, and Africa)
- The three major domestic carriers — T-Mobile, AT&T, and Verizon — account for 66.5% of total 2025 revenue; renewal of 5- to 15-year contracts sustains recurrence
- 2026 guidance nearly flat due to already-quantified churn from Sprint (T-Mobile consolidation) and EchoStar; recovery arrives in 2027 as the Millicom acquisition in Central America matures
- Sustained net buybacks (US$497.8 million in 2025) and a recent rating upgrade to BBB (S&P) following the company's first investment-grade bond
Intrinsic value — two valuation methods
Total return at 5 years: 9.6%/year = 6.8% appreciation + 2.8% dividend. The target price ($259) is ex-dividend; the $30 in dividends collected over 5 years are added separately.
By both methods, the value today (DCF $332 · Multiples $234) exceeds the market price ($186).
Pillars of the analysis
The verdict — today vs 5 years
Today — fairly valued: at $186 trades ~20.3% below its value discounted to today (~$234); the discount is positive but does not reach the margin of safety we require (≥38%).
At 5 years — En valor: the target price ($259) 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 ~$148.
Thesis
The business
SBA is an infrastructure REIT with long-term contracts, contractual escalators, and a hard-to-replicate ground position; the domestic business is mature and concentrated among three clients, while the international business — Brazil, Guatemala, and the rest of Central America — still has a runway for growth via the Millicom acquisition. Business quality is high (return on invested capital of 15.0%, above the 10% bar), but 2026 is a transition year due to the already-declared churn from Sprint and EchoStar.
The valuation
It is valued on P/AFFO — the sector's standard multiple, on the cash that sustains the dividend — with a base-case exit multiple of 17x within the 15-21x band for a tower REIT, reflecting a wide moat but a transition year in near-term growth. AFFO per share grows from the nearly flat level guided for 2026 toward a durable high-single-digit rate by year 5, funded by Millicom's maturation and the end of known churn. The result is a five-year value of $259 per share, against a current price of $186: +10% in annual total return.
The margin of safety
It trades close to intrinsic value, far from the required margin of safety. The market price discounts the 2026 transition year more heavily than the subsequent recovery, without clearly distinguishing the already-quantified one-off churn from structural deterioration. Leverage (6.4x net debt to annualized adjusted EBITDA) sits at the midpoint of the company's own target range (6.0x-7.0x) and is supported by a recently obtained investment-grade rating (BBB, S&P).
What to watch
The central disconfirmer is whether 2026 churn turns out to be the floor or the start of a trend: if domestic carrier consolidation continues beyond Sprint and EchoStar, or if competition from alternative installations erodes pricing power on contract renewals, durable growth by year 5 would fall short of the model and the 17x exit multiple would not hold.
