American Tower Corporation

Key catalysts

• 5G colocation demand

  Carrier network investment can drive new colocations and amendments across American Tower's existing communications sites.

• Contracted site growth

  Long-term leases with escalators and a high proportion of recurring site revenue can support visible organic growth.

• CoreSite demand

  Cloud, interconnection and AI-related demand can improve utilization and expansion opportunities within the CoreSite portfolio.

Principal risks

• Carrier concentration

  Dependence on a small number of major wireless carriers creates exposure to consolidation, churn and customer capital-spending decisions.

• International and currency exposure

  Operations across emerging markets expose reported results and cash flows to currency volatility, regulation and political instability.

• Leverage and interest rates

  Debt-funded infrastructure ownership makes refinancing costs, credit access and interest-rate movements material to cash available for investment and distributions.

American Tower reported first-quarter 2026 results with organic tenant-billings growth, data-center demand and disciplined capital allocation supporting its outlook.

Valuation interpretation

• A defensive infrastructure interpretation depends on recurring tower escalators and carrier investment offsetting churn and financing costs.
• CoreSite can broaden growth, but its capital intensity and competitive data-center economics should be assessed separately from tower cash flows.
