Earlier this week, Barclays upgraded American Tower to “Overweight” from “Equal Weight,” pointing to stabilizing U.S. tower growth, stronger domestic leasing, international expansion, and building momentum in its CoreSite data center business.
Analysts also highlighted that American Tower’s shares appear significantly discounted relative to intrinsic value estimates, even as its earnings multiple sits at a premium to the broader REIT sector.
With this upgrade and the emphasis on CoreSite’s data center momentum, we’ll explore how these developments reshape American Tower’s investment narrative.

What Is American Tower’s Investment Narrative?
To own American Tower, you have to believe in the long-term demand for wireless infrastructure and the company’s ability to translate that into steady cash flows despite mixed share price returns over the past five years. The Barclays upgrade adds some fresh momentum to that story, reinforcing near-term catalysts around stabilizing U.S. tower activity, improving domestic leasing, and renewed attention on CoreSite’s data center assets. It may also help sentiment around a business that screens as undervalued on both DCF and earnings multiples, even after modest recent price gains. That said, the upgrade does little to change the core risks: a balance sheet where debt is not fully covered by operating cash flow, reliance on carrier spending cycles, and the challenge of growing slower than the broader U.S. market. Recent guidance raises keep expectations high, but execution remains crucial.
American Tower’s shares have been on the rise but are still potentially undervalued by 40%. Find out what it’s worth.
