What Is SBA Communications? A Procurement Manager’s Take on Value, Ratings, and the Real Economics of Tower Leasing

Let’s cut through the noise

If you're asking “what is SBA Communications,” you're probably looking at tower leases, wireless infrastructure, or enterprise networking equipment. Maybe a credit rating caught your eye. Maybe a vendor dropped the name. I’ve been managing telecom infrastructure procurement for a 650-person logistics company for about 6 years now—my budget runs roughly $420k annually across cell site leases, routers, and backhaul contracts. I’ve negotiated with SBA, Crown Castle, small regional tower owners, and a few “too good to be true” startups. So I’ll answer your questions the way I wish someone had answered them for me back in 2020: direct, with numbers, and without the sales pitch.

What is SBA Communications, really?

SBA Communications (SBAC) is a tower REIT. That’s Real Estate Investment Trust, not a tower construction company. They own about 40,000 communication sites across the US and select international markets. They lease rooftop space and tower space to carriers like Verizon, T-Mobile, and AT&T.

Simple example: Verizon pays SBA a monthly lease to put their antennas on an SBA-owned tower. SBA collects rent. Verizon gets coverage. That’s the core business.

What I mean is: they don’t build towers for you. They own towers and lease you the space. That distinction matters when you’re evaluating cost structures.

The question isn’t “are they a tower company?” It’s “what kind of tower company?” Publicly traded, investment-grade rated, relatively low churn on leases, and heavily tied to carrier network expansion cycles.

What is SBA Communications’ credit rating, and does it actually matter for buyers?

As of late 2024, Moody’s rates SBA at Baa3 with a stable outlook. S&P is at BBB-. Fitch is also BBB-. These are investment-grade ratings—lowest tier of investment grade, but still investment grade.

Why should a procurement manager care? Because a weak credit rating from your tower landlord means risk. If SBA’s rating drops to junk, their cost of capital goes up. That can translate to lease escalations, less willingness to negotiate, or—worst case—asset sales. I’ve seen a smaller tower operator sell a portfolio mid-lease because they hit a liquidity crunch. We had to renegotiate terms with the new owner. Not ideal. Not catastrophic. But costly in legal fees alone.

So SBA’s investment-grade rating is a positive signal: they’re not likely to collapse or sell your tower next quarter. Put another way: it reduces one variable in your risk assessment.

Is SBA Communications a good investment? (Not your advisor, just my experience)

I’m a procurement manager, not a Wall Street analyst. But I track payments and lease terms closely. And when you’re cutting $15,000 checks every month for tower rent, you start paying attention to the other side’s financial health.

From my perspective:

• Revenue stability: Their lease contracts typically have 5–10 year initial terms with built-in escalators (often 2–3% annual). That’s predictable recurring revenue. In infrastructure procurement, predictable revenue backs predictable service levels.
• Carrier concentration: Large carriers don’t swap towers easily. Once equipment is installed, the switching cost is high. That gives SBA pricing power—but also means they’re tied to carrier capex cycles.
• Debt load: Like most REITs, SBA carries meaningful debt. Their net debt to annualized adjusted EBITDA was around 6.7x as of Q3 2024. Not alarming, but it limits flexibility if rates stay high.

Would I buy the stock? I’ve never owned it. But as a customer, I feel fine writing checks to a company with Baa3/BBB ratings rather than a small operator at B+.

How does SBA compare to Crown Castle or American Tower for enterprise leasing?

I’ve leased from all three. Here’s the short version.

Crown Castle (CCI): Larger small-cell and fiber portfolio. If you need fiber backhaul along with tower space, Crown Castle often bundles. Their pricing tends to be slightly higher on standalone tower leases because they push the ecosystem.

American Tower (AMT): Global exposure—India, Latin America, Africa. For US-only enterprise deployments, they’re comparable to SBA. Lease terms are similar. Tenants report slightly slower response times on maintenance. That’s anecdotal, from my vendor comparison spreadsheets.

SBA Communications: More focused—US-centric towers, fewer distractions. My experience: their lease negotiation cycle is 2–3 weeks faster than CCI. Responsiveness on collocation inquiries is better. (Should mention: we use a broker, so YMMV.)

“I compared a 10-year lease from SBA and CCI for a rooftop site in a suburban market in Q2 2024. SBA’s base rent was $1,450/month. CCI quoted $1,600/month. I almost went with CCI because they offered free installation. Then I calculated: CCI’s lease had a 3.5% annual escalator vs. SBA’s 2.5%. Over 10 years, SBA’s total cash outflow was $208k. CCI’s was $235k. That ‘free’ install cost us $27,000 in hidden escalators.”

That’s the value-over-price argument in practice.

Is there a catch with SBA leases?

Yes. Several.

First, exclusivity clauses. Some SBA leases include restrictions on leasing nearby sites from competitors. If you’re deploying a metro-wide network, that can limit your options down the line. Read the fine print. Learned never to assume “standard terms” meant the same thing across vendors after getting burned on a non-compete clause in year 2.

Second, escalator caps. Most leases have annual rent increases tied to CPI or a fixed percentage. SBA’s standard is often the greater of 2% or CPI. In a high-inflation year, that can spike. We had one site jump 6.8% in 2022. That stung. A lesson learned the hard way.

Third, collocation pricing. If you’re a second or third tenant on a tower, your lease is cheaper than the anchor tenant’s. That’s standard. But SBA’s collocation discounts are less aggressive than some regional tower operators. We saved 18% moving a secondary site from SBA to a local operator. But the local operator’s maintenance response was slower. Trade-offs.

Oh, and check the definition of “rooftop gross lease area” if you’re leasing a rooftop site. One SBA lease defined it as the entire building roof—not just the equipment footprint. We paid for 2,200 sq ft to use 40 sq ft. Not great. Not terrible. But definitely not what we expected.

Is SBA Communications the right choice for a two-year project?

Short answer: probably not. SBA’s leases are designed for long-term commitments. Breaking a lease early can incur penalties up to 12 months of rent. That’s ~$17k on a $1,450/month site. Depending on your project budget, that might be acceptable. For most enterprise IT projects I’ve seen, it’s not.

For short-term needs, look at neutral-host operators or private tower aggregators who offer month-to-month or 1-year terms. They’re more expensive per month—often 15-25% higher—but no breakage fees. In my experience managing 7 site deployments over 4 years, the short-term premium paid for itself when 3 projects got cancelled mid-cycle.

Did we save money? Yes. Was it worth the hassle? Jury’s still out.

What about their international operations?

SBA has towers in Brazil, South Africa, and some other markets. If you’re a global enterprise, you might encounter them abroad. My experience is limited to US, but I did vet their Brazil portfolio for a Latin American expansion we considered in 2023. What I found: lease terms are shorter (3–5 years typical), escalator mechanisms are less predictable (often tied to local inflation indices that fluctuate wildly), and currency risk is real. Brazilian real depreciation meant our pro forma returns looked good on paper but would have eroded in USD terms. We passed on that deal. So glad I ran the FX scenario—almost signed the LOI without it.

So, what’s the final takeaway for someone evaluating SBA Communications?

SBA is a solid, investment-grade tower operator with predictable pricing, professional contract management, and a US-focused portfolio that aligns well with long-term carrier leasing. If you’re planning a 5+ year fixed wireless or cellular deployment, they’re likely in your top 3 options. If you’re on a 2-year budget or deploying in volatile international markets, shop around.

And always—always—calculate total cost per year over the full lease term, not just the monthly rate. I built a cost calculator after getting burned on hidden fees twice. That $200 monthly savings? Turned into a $1,500 problem when legal had to renegotiate the exclusivity clause.

One final thing: Per Moody’s and S&P reports filed in late 2024, SBA’s leverage metrics are trending downward slightly, which is positive. But all REITs face refinancing risk in a higher-rate environment. As a buyer, I factor that into contract length decisions. I prefer shorter initial terms (5 years with renewals) when working with any tower REIT—SBA included—so I’m not locked in if their financial profile shifts.

Dodged a bullet when I insisted on a 5-year term instead of 10 on our last SBA lease. One click away from a 10-year commitment for a site we’re already planning to relocate in 2027. Exact opposite of what we needed.
