The thesis
Why this org is unusual
The most distinctive feature of American Tower’s structure is the reintroduction of a formal COO role in 2025 after the CEO temporarily oversaw global operations.
Steven Vondran served as interim global COO before becoming CEO in 2024, and the company reinstated the COO layer with Eugene Noel in January 2025. This signals a deliberate return to operational separation at the top.
The CEO has a moderate span with seven direct reports, combining classic REIT functions (finance, legal) with operational leadership over towers and data centers. The structure remains functional rather than divisional, with geography and segments largely managed below the EVP level. International operations, previously led by a dedicated president, were folded back into the operating structure after Olivier Puech’s retirement in early 2026.
Overall depth is limited to three to four layers, consistent with a capital‑intensive infrastructure REIT. Strategy, HR and operations are centralized, supporting standardized execution across regions rather than autonomous regional P&Ls.
- COO role reinstated in 2025
- International president role eliminated after retirement
