On September 14, 2026, American Tower Corporation completed a registered public offering of senior unsecured notes. The offering consisted of three tranches totaling $1.6 billion in aggregate principal amount. The company received approximately $1,579.9 million in net proceeds after deducting commissions and estimated expenses.

The notes issued include:

Interest on the notes is payable semi-annually in arrears on March 15 and September 15 of each year, beginning on March 15, 2027. The notes were issued under an indenture dated June 2, 2025, with U.S. Bank Trust Company, National Association, as trustee.

The company intends to use the net proceeds for specific debt repayment and general corporate purposes. Approximately $600.0 million will be used to repay existing 1.450% senior notes due 2026. The remainder will be used to repay indebtedness under the company's $6.0 billion revolving credit facility and for general corporate purposes.

The indenture governing the notes includes covenants that limit the company's ability to merge, consolidate, or sell assets, as well as its ability to incur liens. The company may redeem the notes at any time at its election, with redemption prices varying based on the timing of the redemption relative to the maturity dates.
