American Tower Corporation (AMT) disclosed a significant legal dispute with its customer AT&T Mexico.
AT&T Mexico, which accounted for approximately $300 milliona in tenant revenue for AMT in 2024, has been withholding tower rent payments since early 2025. This situation led AMT to record $10 million in reserves during Q2 2025, with potential for further reserves if the dispute continues. The company asserts strong defenses and confidence in the Master Lease Agreement (MLA) with AT&T Mexico, with arbitration slated for August 2026.
In addition, the company provided an update on its relationship with DISH Network. DISH represents a smaller portion of AMT's overall revenue (2%b total, 4% U.S. & Canada), with a Master Lease Agreement in place until 2036. Investors should monitor the resolution of the AT&T Mexico dispute, as it could impact future revenue and profitability.
