Segment Information Segment Information
We are one of the largest specialty contractors in the United States and a leading provider of electrical and mechanical construction and facilities services, building services, and industrial services. Our services are provided to a broad range of commercial, technology, manufacturing, industrial, healthcare, utility, and institutional customers through approximately 100 operating subsidiaries. Such operating subsidiaries are organized into the following reportable segments, which additionally reflect the nature of the services offered:
•United States electrical construction and facilities services;
•United States mechanical construction and facilities services;
•United States building services; and
•United States industrial services.
On December 1, 2025, we sold EMCOR UK, the results of which were previously reported within our United Kingdom building services segment.
Our chief operating decision maker (“CODM”) is our Chairman, President, and Chief Executive Officer. Our CODM is responsible for assessing the performance of the Company and each of our reportable segments as well as allocating resources, including personnel and capital resources. The measure of segment profit or loss utilized by our CODM is operating income. Our CODM evaluates segment performance by comparing historical, actual, and forecasted operating income on a regular basis. The accounting policies of our reportable segments are the same as those applied at the consolidated financial statement level.
The following tables present the revenues and operating income for each of our reportable segments for the three and six months ended June 30, 2026 and 2025 (in thousands):
