SBA Communications Corporation (NASDAQ:SBAC) closed at $182.49 on October 9. The stock has returned -17.1% during the last 6 months, compared to a 24.3% return for the Insider Monkey Billionaire Index and 15.1% for State Street SPDR S&P 500 ETF Trust.
A company can be impossible to compete with and still have nowhere left to grow. SBA owns the ground underneath American mobile coverage and can do very little with it. The scarcity that makes the position unassailable is the same scarcity that caps it.

Permission, Not Steel, Is the Asset:
A cell tower is a simple structure. Permission to put one somewhere useful is not. Local zoning rules make a new tower slow and often impossible, so the one already standing keeps its position indefinitely. That is the asset, and the steel is incidental.
The economics follow directly. Adding a second tenant to a tower already standing costs almost nothing, because the structure, the ground lease, and the maintenance are paid for. Rent from that tenant drops almost intact into operating profit.
Run that for twenty years, and you reach an operating margin of 52.16% in a business whose product is somewhere to bolt an antenna. Leases run for years with fixed escalators written in, so the revenue is visible long before it arrives. Zoning protects more than towers, and the same permitting barrier sits underneath the data center and fibre REITs analysts have been backing.
This is a moat enforced by municipal government rather than by brand or habit, and it does not erode.

Three Major Customers Is the Whole Problem:
A moat protects a company from its competitors. It does nothing about its customers. American carriers consolidated into a handful of buyers, so the tower owner negotiates with very few counterparties. All of them are large, and all of them know the towers are already built and that keeping an existing tenant costs almost nothing.
The consequence shows up in growth rather than margin. Revenue grew 2.30% in the most recent quarter, which is what the widest moat in American infrastructure currently produces.
The balance sheet removes any margin for error. Debt of $15.21 billion against a cash balance in the low hundreds of millions has pushed book value below zero, and short-term obligations run to roughly six times short-term assets. None of that threatens anything while the rent arrives on schedule, and all of it matters if the carriers ever press on renewal terms. Three major customers is a short list for an asset built to stand thirty years, which is the same concentration running through the twelve REITs Goldman Sachs picked.
The Valuation Case:
The clearest signal in the file is that the forward multiple sits above the trailing one, at 22.31 against 19.69, on analyst consensus estimates. That ordering is unusual, and it is not ambiguous. The market expects less profit next year than last, and buyers are paying more for a dollar of future earnings than for a dollar already delivered.
The verdict is that the stock looks fairly priced for the certainty of its cash flows and expensive for the growth attached to them. It is not cheap despite trailing the market badly, because the price is paying for the moat and looking past the ceiling directly above it. Enterprise value against EBITDA of 17.16 is the honest yardstick, since negative equity makes book value meaningless. Safety is easy to buy and expensive to own, which is what separates SBA from the quality companies still trading at a discount.
Conclusion:
Permanence and growth turn out to be different things. Zoning rules make this position close to unassailable, and they turn more than half of revenue into operating profit on contracts signed years ahead. However, it protects a business with only a handful of available customers, which is why revenue barely grew and why the forward multiple sits above the trailing one. The market is paying a premium for safety and receiving no growth with it. The open question is whether revenue can grow at all from its three major customers.
