AECOM’s legacy contractor charge obscures a high-quality infrastructure consultancy with record backlog, improving margins, and material re-rating potential.
Overview
AECOM is a global, asset-light infrastructure consulting firm spanning advisory, architecture, engineering design, program management and construction management. Its 51,000-employee technical platform and ENR-ranked global scale allow it to compete for complex, multi-billion-dollar programs while avoiding much of the capital and commodity exposure of traditional contractors. Government clients represent approximately 60% of revenue, with transportation, water, environmental, facilities and energy markets providing non-discretionary demand. **The core investment case is a transition away from legacy at-risk construction toward higher-margin design and advisory services.** Q3 FY2026 was distorted by a $337 million pre-tax legacy project charge: GAAP revenue fell 14.2% to $3.586 billion and GAAP diluted EPS was a $0.65 loss, but underlying adjusted EPS was $1.49, up 11% and above the $1.46 consensus. Backlog reached a record $27.82 billion, up 13%, with 1.6x design book-to-burn. The stock at $75.84 trades near 12.7x forward P/E versus approximately 22x for WSP and Stantec. **Backlog conversion, cash-flow recovery and AI-enabled margin expansion are the principal catalysts.**
