American Tower (AMT) Stock Rallies On Raised Guidance Despite Debt Strain

American Tower stock closed up almost 3% to US$171.70, which is a sharp move for a tower and data center real estate investment trust. The excitement is about one thing more than anything else. Investors are cheering a headline quarter built on raised guidance and stronger funds from operations, the key cash flow metric for this sector.

The tension today is simple. The price jump suggests relief and renewed confidence after a flat few months. The fundamentals show a company lifting property revenue and adjusted funds from operations expectations, while still carrying a balance sheet that needs close watching.

Is American Tower stock priced like a bargain given a 23.5x P/E and a share price well below the US$278.52 fair value estimate, or is the weak debt coverage a red flag? Compare both sides using our valuation analysis for American Tower.

American Tower results reinforce bullish revenue story

For investors leaning positive on American Tower, the latest quarter broadly supports that stance. Property revenue, adjusted EBITDA and attributable AFFO per share guidance all moved higher, which fits a view of a resilient infrastructure landlord. CoreSite delivered record leasing and around 12% cash revenue growth, and its 2026 outlook points to mid teens revenue growth. Organic tenant billings looked healthier once DISH churn is stripped out, particularly in Europe and Africa. The share price gain of about 3% after results suggests the market welcomed this confirmation.

Debt, churn and services keep the bear case alive

The cautious side of the story also has support. Management still calls 2026 a trough year for AFFO per share growth due to DISH churn, refinancing costs and softer services. Cash adjusted EBITDA margin compressed, and even though margin expands excluding DISH, it shows how exposed American Tower is to single customer swings. Leverage at 4.9x sits at the top of the target range, which keeps debt metrics in focus. Latin America organic billings falling and services revenue stepping down underline that not every part of the portfolio is firing.

After a year that management itself describes as a trough for AFFO per share, and with debt coverage already under pressure, it is worth asking whether these headwinds are isolated or point to deeper structural issues in American Tower’s model.
