American Tower (AMT) Q4 FY25 earnings call: guidance and Q&A

Inquired about the pacing of carrier activity, the mix of amendment vs. densification, and how 2026 leasing growth compares to 2025 ex-DISH.

Management noted steady carrier activity, a higher incidence of new colocations, but still a healthy amendment pipeline. Some carriers are done with initial 5G overlays, shifting to densification. Rod Smith clarified that 2026 colo and amendment contribution (2.4%) is consistent with 2025 levels (ex-DISH), with a slightly higher pace in H1.

“We are seeing a higher incidence of new colocations coming in, but we still have a pretty healthy amendment pipeline as well. And this is what we would expect to see at this point in the cycle.”

Asked about the amount owed by DISH, comparing it to Crown Castle's stated $3.5 billion, and management's M&A outlook given public vs. private multiple disparity.

Management stated DISH's exposure is approximately 4% of U.S. revenue, or ~$200 million annually through 2035-2036, and they will pursue litigation for collection, which would be incremental upside. They are not seeing attractive M&A deals due to valuation disconnects, focusing on developed markets and not emerging markets for M&A.

“We don't plan to speculate on the litigation. It's public and you guys can follow along as you go. This is going to take time to work out. And so we don't necessarily expect this to get resolved this year.”

Asked for a breakdown of the 200-300 bps margin expansion target by 2030, distinguishing organic operating leverage from new efficiency initiatives.

Management stated the 200-300 bps target fully encapsulates the outlined initiatives (land expense, sourcing, maintenance, tech platforms) but AI could offer incremental upside. They emphasized it's a continuation of existing cost management efforts, now focused on direct expenses, building on an already industry-leading margin base.

“We set a stretch target for ourselves. And we do think that, that 200 to 300 points of margin expansion represents some nice improvement over what it would otherwise be if we weren't able to recognize these cost savings.”

Inquired if fixed wireless drives dedicated site investments, what AI use cases are most promising for traffic growth, and about reported CoreSite land purchases in Bay Area and Dallas.

Fixed wireless uses existing installations, contributing to overall mobile data demand. AI traffic growth is expected from video upstreaming/manipulation and live-streaming applications, potentially shifting network architecture towards higher upload capacity (e.g., >20%). CoreSite is selectively looking at new markets and has purchased land, with new facilities taking 2-3 years to bring online, driven by strong demand for interconnection-rich data centers and AI workloads.

“Some of the projections we've seen are showing that the upstreaming effects of AI could require a change in network architecture where most networks today have about 10% dedicated to upload and 90% to download... We think that in the future AI could change that trajectory a bit so that you're seeing north of 20% in terms of upload capacity.”

Asked about the strategy for smaller emerging markets (capital recycling) and how LEO satellite constellations might affect the terrestrial tower business by 2030.

The company continuously evaluates smaller emerging markets for accretive value realization, but will not conduct fire sales. They have changed their operating model to reduce distraction. Regarding satellites, the investment in AST SpaceMobile provides insight, and they believe satellites will be complementary to terrestrial networks, with towers remaining the cheapest and best way to deliver mass mobile data due to physics and economics.

“Towers will always be the cheapest and best way of deploying the level of content, the volume of mobile data that consumers demand. So while we think the satellite business is a great business, it's going to be a good complement to the networks... we see no risk at all to the tower business over the long term.”

Inquired if U.S. colo/amendment activity is down over the last 3 years (ex-DISH), why H2 2026 is lower than H1, and the impact of a large African customer acquiring towers.

Rod Smith clarified that the slightly lower H2 2026 pacing is due to holistic agreements and timing, not a trend. He noted that while initial 5G saw record new business, current activity (mid-$30B CapEx) is consistent with prior years ex-DISH. Steve Vondran stated the African customer's tower acquisition is not expected to impact AMT's business, as AMT is reducing incremental capital in Africa and expects continued organic growth.

“The thing that is different going forward is that we have a different global structure. We have the addition of a Chief Operating Officer that is going to be bringing best practices around the globe in terms of the way we manage land expenses, the way we execute on supply chain and sourcing.”
