AMT Q3 2026 Earnings Analysis

Thanks, Alex. And yeah, this was a busy one. American Tower is basically two businesses in one now — the classic tower leasing business, and this increasingly dominant data center play through CoreSite. Let's start with the headline numbers.

That trajectory is wild — 13, to 15, to 16% in just three quarters. It tells you demand from cloud and AI customers is accelerating faster than even AT themselves expected. CEO Steven Vondran called it "record leasing activity," and CFO Rodney Smith backed that up with some eye-popping details — cash mark-to-market on renewals running in the double digits this quarter, versus the usual 3-4%.

Exactly — and that's the kind of pricing power you want to see. Though Rodney did caution the full-year number will normalize closer to 6%, so don't extrapolate that double-digit renewal pricing for the whole year.

That multiple is really the headline there. It tells you the market is willing to pay up for quality tower assets — and it validates how much value is baked into AT's North American portfolio generally. Management's framing this as "capital recycling" — take proceeds from a slower-growth market and redeploy into CoreSite, debt paydown, and buybacks.

That's a real signal of confidence from management. And leverage sits at 4.9 times net debt to EBITDA — comfortably inside their 3-to-5x target range, with the best credit rating in the tower peer group. So they've got real flexibility to keep doing all of this at once: buybacks, debt reduction, and growth investment.

This was probably the most forward-looking moment on the call. Analysts kept pushing on it, and Vondran's answer was basically: "Anyone building wireless infrastructure at scale in the US has to come to us." He pointed out AT already owns the equipment DISH abandoned in bankruptcy — including potentially valuable spectrum-adjacent gear — and they can make that available to any interested party.

It's speculative upside right now, not baked into guidance at all, but it's a potential new tenant category that didn't exist a year or two ago.

Right, and that connects to the broader growth story. Rodney walked through the AFFO-per-share bridge really clearly: 2026 is basically flat on an FX-neutral basis once you adjust for refinancing costs, but that's because of three temporary headwinds — DISH churn, a services revenue pullback, and refinancing costs — worth roughly 600 basis points combined. Strip those out, and the underlying growth rate is closer to 7%.

And layered on top of that, you've got four long-term catalysts Vondran described: the capacity phase of 5G, a new spectrum cycle starting with upper C-band in 2027, the eventual 6G transition, and AI-driven traffic growth, which CTIA expects to grow three times faster than regular wireless traffic.

So what does this mean for investors going forward? You've got a tower business that's steady and set to accelerate once DISH-related noise clears, a data center business compounding at mid-teens-plus growth with real pricing power, a cleaner balance sheet after the Canada sale, and aggressive capital return through buybacks. The risks are real — ongoing litigation with AT&T Mexico, the DISH mediation outcome, and services revenue timing shifts — but management seems to be executing a pretty disciplined playbook.
