The thesis
Why this org is unusual
Aramark’s most distinctive structural feature is its use of two parallel Chief Operating Officers, one for U.S.
Food & Facilities and one for International operations. This split mirrors the company’s two reportable segments and places both COOs directly under the CEO, rather than routing operations through a single global COO. The structure emphasizes geographic and regulatory complexity as the primary axis of management.
The CEO’s direct span includes finance, legal, HR, and both operating leaders, producing a relatively tight executive layer for a company with more than 260,000 employees. Finance and governance functions remain centralized, while operations are clearly bifurcated. This hybrid enterprise structure balances functional control with regionally focused execution.
- Dual COO structure
- No standalone corporate COO
The comparison

Compared with peers such as Sodexo and Compass Group, Aramark’s dual-COO model is more explicit in separating U.S. and international accountability at the top. Many competitors rely on a single global COO or regional presidents reporting through an intermediate layer. Aramark’s approach reduces ambiguity in P&L …
