American Tower Corporation (AMT) is conducting a primary debt offering of three tranches of senior unsecured notes maturing in 2031, 2033 and 2036. The notes pay cash interest semi-annually on March 15 and September 15, beginning March 15, 2027, and rank equally with all other senior unsecured debt of American Tower, while being structurally subordinated to obligations of its subsidiaries.
The notes are redeemable at American Tower’s option, with a make-whole style redemption prior to specified dates close to maturity and at 100% of principal plus accrued interest thereafter. Holders have a right to require repurchase at 101% of principal plus accrued interest upon a Change of Control Triggering Event. There is currently no public market and the notes will not be listed on an exchange.

As of June 30, 2026, it reported cash and cash equivalents of $1.76 billion, total long-term debt of about $37.19 billion, and total equity of about $10.25 billion, illustrating a highly levered but sizeable capital structure.
