Earnings enjoyed a strong boost from robust cost controls. American Tower’s operating expenses came in 20% below the year-ago period’s figure, driven by dramatically lower depreciation, amortization, and accretion costs.

Shifting revenue streams, strong cash flow
It should be noted that American Tower’s success goes beyond accounting adjustments. The new amortization schedule doesn’t affect the company’s free cash flow, which rose 22% year over year to $746 million.
More than half of American Tower’s revenue came from the three largest U.S. wireless phone networks, but most of the recent revenue growth comes from the smaller data center segment. And yes, American Tower is tapping into the ongoing artificial intelligence boom.
