AECOM
Summary
What they do:
One of the world's largest engineering and professional services firms — provides design, engineering, construction management, and program management for data centers, infrastructure, and industrial projects, with a dedicated data center practice that grew 50% in FY2025.
Why they matter:
Hyperscalers planning $200B+ in data center capex need someone to design, engineer, and manage construction of these facilities. AECOM's 50,000+ engineers provide the integrated design-to-commissioning services that reduce schedule risk on multi-billion-dollar builds.
Recent performance:
Q1 FY2026 (ended Dec 2025) revenue $3.83B (beat $3.65B estimate), record NSR, adjusted EBITDA, and margins. Backlog up 9% to all-time high. FY2026 guidance raised: adjusted EPS $5.85-$6.05, EBITDA $1,270-$1,305M. Stock ~$86, market cap ~$11B.
Our Verdict
A diversified engineering giant with a fast-growing data center practice benefiting from the hyperscaler buildout, but at ~15x forward P/E the stock prices in the infrastructure cycle without yet proving that data center services become a durable high-margin franchise — an emerging play needing sustained data center backlog growth to re-rate.

AECOM is a global professional services and engineering firm with ~$16B in annual revenue and 50,000+ employees across 150+ countries. The company designs, engineers, and manages construction for everything from highways and water treatment plants to data centers and renewable energy facilities. Revenue comes through two primary modes: Design & Consulting Services (~55% of net service revenue) and Construction Management & Program Delivery (~45%).
The business model is asset-light and labor-intensive. AECOM employs engineers, architects, and project managers who bill time against client projects. Gross margins are 28-32%, constrained by labor costs. Operating margins run 8-12%. Capital expenditure is minimal (~2-3% of revenue) since the company doesn't build anything — it designs and manages the building. Free cash flow is guided to ~$400M for FY2026.
The data center practice is the AI story. As hyperscalers build massive AI training and inference facilities, they need engineering firms to handle site selection, structural and MEP (mechanical, electrical, plumbing) design, power distribution engineering, cooling system design, construction oversight, and commissioning. AECOM's data center practice grew 50% in FY2025 and represents a growing share of the backlog. Each hyperscale data center campus requires $50-200M in engineering and construction management services — a meaningful revenue opportunity per project.
Q1 FY2026 was a record quarter: revenue $3.83B beat estimates, adjusted EBITDA margins expanded, and backlog hit an all-time high with a 1.5 book-to-burn ratio despite a 43-day US federal government shutdown. Management raised full-year guidance across all metrics: adjusted EPS to $5.85-$6.05, EBITDA to $1,270-$1,305M, and organic NSR growth of 6-8%.
Supply Chain Dependencies
The Catch
Engineering services are a people business with structurally low margins. AECOM's operating margins (8-12%) are a fraction of what chip designers, equipment makers, or software companies earn. Even if the data center practice grows rapidly, it doesn't fundamentally change the margin profile — AECOM still needs to hire and retain expensive engineers for every project, and those engineers can leave for competitors or clients. The data center capex cycle is also inherently cyclical: hyperscalers will eventually build enough capacity, and new construction slows. When that happens, AECOM's data center practice shrinks while the fixed-cost engineering workforce creates operating leverage on the downside. Additionally, $5B in net debt at 2.8x leverage limits AECOM's ability to invest in growth or return capital to shareholders during the cycle.
If They Win
If the data center practice continues growing at 50%+ annually and becomes $1B+ in revenue by FY2028, while infrastructure spending (BIL, renewable energy) provides a steady base, AECOM transforms from a generalist engineering firm into the go-to design and program management partner for the AI infrastructure buildout — the firm hyperscalers call first when planning a new $2B data center campus. Revenue crosses $20B. EBITDA margins expand to 18%+ as higher-margin advisory and program management grow faster than labor-intensive design. Free cash flow hits $600M+, enabling debt reduction to <2x leverage and meaningful shareholder returns. The installed base of data center client relationships creates a recurring consultancy flywheel as facilities require ongoing optimization, expansion, and technology upgrades.
