Filed September 24, 2025For Securities:AMT

Summary

American Tower Corporation (AMT) has resolved a significant legal dispute with its major customer in Mexico, AT&T Comunicaciones Digitales, S. de R.L. de C.V. (AT&T Mexico), which was causing the withholding of approximately $300 million in annual tenant revenue since early 2025. The agreement reached on September 23, 2025, is a positive development for investors as it secures a substantial portion of the overdue and future rental payments. The resolution involves AT&T Mexico remitting the majority of withheld rents and resuming regular monthly payments. However, a portion of the outstanding and future unpaid amounts will be held in an irrevocable escrow account, pending the outcome of the ongoing arbitration or mutual agreement between the parties. This structured approach mitigates immediate financial risk while the final resolution is pursued, providing a clearer path forward for revenue recognition.
