Key Takeaways

• American Tower rents space on communications towers to wireless carriers under long-term leases with built-in escalators, about 84% of revenue, and runs a CoreSite data-center business, about 16%, that is now its fastest-growing piece. • The clearest risk is the balance sheet typical of a tower REIT: the business is built on large, long-dated debt, and management itself flags that leverage and debt-service obligations can constrain the company, especially as notes refinance at higher coupons.
