SBA's tower cash flow keeps holding steady while every big churn event lands in the same stretch, leaving leasing growth at what management calls the bottom. The next leg up depends on spectrum auctions and edge computing that are still years away. How does SBA's growth trough compare with its last two cycles?
Growth is at the bottom because every churn event landed at once.
Sprint, EchoStar and carrier mergers abroad all hit in the same stretch. Management calls this 'probably the bottom' and still guides to 4% to 5% domestic growth, but nothing in the results yet shows it turning up. How much of the 2026 churn rolls off by the end of 2028?
The Verizon agreement turns a top customer into contracted growth.
A new long-term deal sets minimum colocation commitments instead of site-by-site negotiation, and domestic backlog grew after it was signed. That gives SBA a predictable slice of new rent while other carriers stay careful with spending. How much of the Verizon commitment is already in the backlog?
New towers and edge computing eat cash before they earn anything.
SBA is building roughly 600 new towers this year, mostly in Central America, plus early edge-computing trials at tower sites. The edge spending has no revenue date attached, so cash goes out years before the income arrives.
Bullish
Verizon's minimum commitments run for ten years. A floor under the rent means SBA can keep raising its dividend even in quarters when carriers sign nothing new.
Management calls 2026 the peak year for international churn. Once the mergers and bankruptcies stop eating revenue, the same towers start adding tenants again with no new spending.
The upper C-band auction comes with hard build-out deadlines. Winners who miss the deadline lose the spectrum, which forces the network spending that tower owners get paid for.
Bearish
EchoStar stopped paying and says in court it owes a fraction. The revenue is already out of guidance, so a court loss means money SBA was counting on never comes back.
Carriers are cutting staff and reviewing what they pay for sites. If that squeeze continues, leasing stays well below the growth SBA targets and the recovery slides past 2027.
Edge computing and satellite revenue are years from mattering. SBA is spending on trials now for money management will not put a date on, so towers carry the story alone.
