EMCOR's Electrical Revenue Grew 44% and Its Margin Reached 13.3%

EMCOR Group reported third quarter results on Oct. 29 showing that its United States electrical construction and facilities services segment generated $1.85 billion of revenue, up from $1.29 billion in the same quarter of 2025. Operating income in that segment was $247.0 million, or 13.3 percent of revenue, against 11.3 percent a year earlier. Company-wide remaining performance obligations, the dollar value of contracted work not yet performed, reached $18.57 billion at Sept. 30, an increase of $5.96 billion, or 47.2 percent, over twelve months. Quarterly revenue was a record $5.54 billion, up 28.8 percent.

Quanta Services reported the same morning. Its revenue rose to $12.01 billion from $7.63 billion, and its total backlog reached a record $63.7 billion, against $39.2 billion a year earlier. Quanta's twelve-month backlog, the portion it expects to perform inside a year, climbed to $38.4 billion from $22.3 billion. Its electric segment booked $9.80 billion of revenue at a 12.6 percent operating margin, up from 11.4 percent. Both companies raised full-year guidance, EMCOR to a range of $20.6 billion to $21.0 billion of revenue and Quanta to $41.3 billion to $41.6 billion.

EMCOR named the source of the backlog growth directly. The company said the most significant increase occurred in its network and communications market sector, where, in its words, mission critical facilities continue to require substantial electrical infrastructure and increasingly sophisticated cooling systems. Network and communications is the category under which EMCOR reports data center and other mission critical facility work. The company listed healthcare, water and wastewater, institutional, and manufacturing and industrial work as additional contributors.

The margin split inside EMCOR is the detail that changes what the work looks like. The electrical segment's margin widened by 200 basis points year over year. The United States mechanical construction segment moved the other way, to 12.1 percent from 12.9 percent, on revenue that grew at a comparable rate. At a contractor that performs both trades at scale, electrical scope is returning more per dollar of revenue than mechanical scope, which is what happens when the electrical package is the part of a job that is hardest to staff and schedule.

For hiring, a remaining performance obligation is a staffing commitment. Work booked at Sept. 30 and not yet performed has to be manned, and $18.57 billion of it extends well past one construction season. EMCOR's chairman and chief executive, Tony Guzzi, credited results to the expertise of the company's foremen, superintendents, project managers and operating leaders. Quanta's chief executive, Duke Austin, pointed to the fungibility of the company's skilled workforce across multiple end markets and said there is an opportunity for strong double-digit adjusted earnings growth in 2027. Neither executive described contracted volume as the constraint. Both described people. A contractor that expects to grow earnings in 2027 off work already signed is hiring against a schedule rather than against a bid pipeline.

Backlog of that size converts into journey-level openings and foreman assignments on mission critical sites, and it is already under contract.
