Frequently Asked Questions

The primary purpose of this $850.0 million debt issuance is to repay existing indebtedness under American Tower's senior unsecured revolving credit facility. This effectively refinances short-term or variable-rate debt with longer-term, fixed-rate notes, potentially improving the company's financial flexibility and reducing interest rate risk.

The notes are 4.700% senior unsecured notes due December 15, 2032. Interest is payable semi-annually on June 15 and December 15, commencing June 15, 2026. The notes mature on December 15, 2032. The indenture also contains covenants and redemption provisions as detailed in the filing.

The indenture governing the notes includes covenants that limit American Tower's ability to merge, consolidate, sell assets, and incur liens. These restrictions are standard for such debt issuances and are subject to specified exceptions, including a leverage test based on Adjusted EBITDA that allows for the incurrence of liens up to 3.5x Adjusted EBITDA.

American Tower may be required to repurchase all of the notes at a price of 101% of the principal amount plus accrued interest if a 'Change of Control' event occurs, followed by a 'Ratings Decline,' as these terms are defined within the indenture. This provides a layer of protection for noteholders in specific adverse corporate event scenarios.
