Earnings Call Summary
American Tower had a strong first quarter with reported revenue of $2.74 billion, beating consensus by about $53 million, and earnings per share of $2.84 versus consensus of $2.50. Organic growth excluding DISH churn was 4 percent in towers and 17 percent in the CoreSite data center business, driven by growing mobile data demand, AI workload expansion and a major inflection in interconnection activity. Management emphasized that structural tailwinds including 5G densification, eventual 6G deployment, and AI-driven infrastructure needs position the company well for mid to upper single-digit annual growth going forward.
Guidance Management raised full year property revenue guidance by about $145 million to approximately $10.9 billion, driven by foreign exchange tailwinds and accelerated straight-line revenue. They expect organic tenant billings growth around 4 percent when excluding one-time DISH churn, plus data center growth of about 13 percent. They reaffirmed attributable AFFO per share growth expectations in the mid to upper single-digit range over the long term.
Fine but not compelling. Acceptable results that likely do not create a meaningful forward reset.
Dividend
The company pays an annual dividend rate of $7.16 per share.
