The money buying construction firms has changed hands. For the first time, private-equity buyers accounted for 54.3% of construction M&A in 2025, driving 305 deals, according to deal trackers. That tips the sector past a threshold: financial buyers, not strategics, now set the pace. What they’re chasing says a lot about where the industry’s value is moving.
What PE is actually buying
Two themes dominate. First, data-center and power-infrastructure contractors are the hottest targets, riding the AI and electrification build-out that’s pulling tens of billions into specialized electrical and mechanical work. Second, and more revealing, buyers are acquiring subcontractors as a shortcut to skilled labor. In a market short hundreds of thousands of workers, buying a firm with a trained crew can beat trying to hire one.
That reframes a sub from a margin-thin trade shop into a strategic asset. The crew is the product. For owners of well-run specialty firms, it’s a seller’s market in a way it rarely has been.
The risk under the roll-up
Roll-ups look clean on a spreadsheet and get messy in the field. Construction runs on relationships, local knowledge, and crews that can walk if they don’t like the new owner. Private equity’s playbook, consolidate back office, standardize systems, expand regionally, works better in software than on a jobsite where every project is a one-off.
There’s also the cycle. Buying at elevated multiples into electrification demand assumes that demand holds through the hold period. If data-center starts cool, some of these platforms will look expensive. None of that stops the trend. The capital is committed and the labor logic is sound. But the firms that win won’t be the ones that bought the most. They’ll be the ones whose crews stayed.
