EMCOR Group, Inc.

The record $13.25B RPO backlog at year-end 2025 (up from $10.10B a year earlier) provides approximately nine months of forward revenue coverage, with the network and communications sector alone contributing $4.3B. Roughly 18% of revenue comes from building services contracts that renew annually, while the majority is project-based construction without subscription-style recurrence.

Revenue is spread across electrical construction (roughly 30%), mechanical construction (roughly 42%), building services (roughly 18%), and industrial services (roughly 7%) in FY2025. Electrical and mechanical segments serve overlapping end markets and follow the same capital-spending cycle, limiting effective diversification, while building services adds modest defensive stabilization.

After the divestiture of EMCOR UK in Q4 2025, approximately 97% of revenue originates from the United States, with no meaningful international operations remaining. The single-country footprint concentrates revenue sensitivity entirely on U.S. non-residential construction investment, government infrastructure spending, and domestic industrial capex cycles.

EMCOR is fundamentally a trade-labor business where cost structure scales near-proportionally with revenue volume, limiting structural operating leverage. Non-GAAP operating margin was approximately 9.4% in FY2025, reflecting a project mix weighted toward more complex data center and industrial work rather than inherent scalability from fixed-cost economics.

The roughly 18% building services segment consists of recurring maintenance and service contracts that are mission-critical and renew annually, representing the highest-quality revenue layer. The majority of revenue is project-based construction that is non-recurring, competitively bid, and dependent on customers' capital investment decisions, producing a mixed overall quality profile.
