A U.S. specialty contractor behind big electrical and mechanical projects—data centers, high-tech factories, and commercial buildings—plus ongoing maintenance, HVAC retrofits, and industrial work like refinery turnarounds and specialty welding. Its roots go back to 1966, when it started as the Jamaica Water Supply Company, a New York water utility that grew into the sprawling JWP Inc. before emerging from a 1990s restructuring under the name EMCOR—a brand hinting at electrical and mechanical construction.

Select a row to see that insider’s individual transactions. † Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 6 months: -51.9K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
