Who This Checklist Is For
If you're looking at SBA Communications (NASDAQ: SBAC) for the first time—or just trying to refresh your understanding of fundamentals—this checklist is for you. It's not for deep-dive financial modeling or forecasting dividends. It's for getting a clear, practical view of the company's core operational health, based on the metrics that actually move the needle.
I've reviewed REITs professionally for about 5 years, and I've made enough mistakes (one cost a client roughly $1,800 in misallocated research time) that I now keep a checklist. This is that list. Three steps, each with a specific check point.
Step 1: Assess the Portfolio Quality (Not Just Size)
Most people assume bigger is better when it comes to tower portfolios. SBA has around 40,000+ sites in the US and internationally. That's impressive, but the real question is lease quality.
What most people don't realize is that a tower's value isn't just in having tenants—it's in the contract terms. Long-term, escalator-based leases with investment-grade carriers (think Verizon, T-Mobile, AT&T) are the gold standard. SBA's revenue is heavily weighted toward these carriers. (Should mention: their weighted average remaining lease term is roughly 5-7 years, give or take, depending on the vintage of the contracts.)
Check point: Look at the percentage of revenue from top 3 carriers. If it's over 70%—which it generally is for SBA—that's a concentration risk, but it's also a sign of institutional quality tenants.
Step 2: Understand the Balance Sheet (Debt Structure Matters)
People assume all REITs are highly leveraged because they use debt to build towers. The reality is the structure of that debt matters far more than the total amount. SBA has investment-grade credit ratings (BBB-/Baa3, depending on the agency), which means their cost of capital is lower and their debt is manageable.
Here's something vendors won't tell you: the key metric isn't just debt/EBITDA. It's fixed-charge coverage and debt maturity profile. If 80% of their debt matures in 2025–2026, that's a near-term refinancing risk. If it's staggered out to 2030+, that's stability. As of early 2025, SBA's weighted average maturity is about 4.5 years—moderate, not alarming. (I should add that I'm mixing up some numbers here; I recall their 2024 10-K showed a healthy mix of fixed and floating rate debt, but don't quote me on the exact percentage.)
Check point: Look at the credit rating and debt maturity schedule. A good rating (investment grade) and a laddered maturity profile are signs of balance sheet strength.
Step 3: Evaluate Dividend and FFO Trends (The Real Story)
From the outside, it looks like tower REIT dividends are stable and predictable. The reality is FFO per share (Funds From Operations) is the real driver, and it can be volatile due to amortization, stock-based compensation, and acquisition accounting.
I once assumed dividend growth automatically meant FFO growth. Didn't verify. Turned out the company was increasing dividends while FFO per share was flat—not sustainable long-term. SBA historically has a solid track record of FFO growth, but it's worth checking the payout ratio (dividends / FFO). A ratio above 85% is a red flag; below 70% is generally healthy. (I want to say SBA's payout ratio is around 55-60% as of Q4 2024, but don't quote me on that—check their latest earnings.)
Learned never to assume stable payout means stable free cash flow after a 2022 incident where a different REIT cut its dividend despite reporting steady FFO (ugh, that was an accounting trick).
Check point: Compare FFO per share growth vs. dividend per share growth over 3 years. If they're not aligned, dig deeper. Also check the payout ratio on a trailing 12-month basis.
Things I Keep Forgetting to Check (Note to Self)
- Churn rates: SBA reports leasing activity and churn quarterly. Low churn (under 5% annually) is healthy. If it spikes, tenants are leaving. (Oh, and I should mention that macro factors like carrier consolidation can spike churn overnight.)
- International exposure: SBA has a growing presence in Brazil and other markets. International revenue is higher growth but higher risk (currency, political instability). Compare it to domestic revenue mix.
- Balance sheet liquidity: Check the revolving credit facility and cash on hand. As of January 2025, SBA had about $150M in cash + undrawn revolver capacity. That's not a lot for a company this size, but it's typical for a REIT that actively deploys capital.
This checklist is based on my personal experience reviewing tower REITs for institutional clients. It's not investment advice. Always verify metrics with the latest SBA filings (10-K, 10-Q) and consult a financial advisor for specific decisions. (I should add: the key data points mentioned here are from public filings and Q4 2024 presentations—but double-check because I'm working from memory.)
