The scramble to wire America’s grid is now driving billion-dollar deals. MasTec agreed on July 9 to buy Superior Group for $1.65 billion in cash, a move that instantly bulks up its utility services arm with electrical crews and heavy equipment it would take years to hire and buy on its own.
What MasTec is buying
Superior brings a deep bench of specialized electrical technicians and a large fleet of equipment, exactly the resources in shortest supply as utilities race to build and upgrade high-voltage transmission. The all-cash deal is expected to close in early in the third quarter. For MasTec, it’s a bet that owning the labor and iron outright beats competing for it on the open market.
Why deals like this are happening
Grid modernization has become a bottleneck. Federal clean-energy funding, data-center load, and industrial electrification are all pulling on the same limited pool of transmission contractors, and demand is outrunning what any single firm can staff by hiring. Buying a competitor is the fast way to add capacity. That’s why power-infrastructure and data-center contractors have become the most sought-after acquisition targets in the sector, with private equity rolling up specialty electrical shops across the country.
The through-line is electricity. The same load growth driving these deals is behind the transmission and interchange work on corridors like the I-41 expansion in Wisconsin, where utility relocations shadow every phase of highway construction.
What it signals
Consolidation at this scale tells you where the money thinks demand is going. Transmission and substation work is the constraint on everything downstream, from AI data centers to reshored factories, and contractors are being priced accordingly. Expect more $1 billion-plus deals as the biggest players buy their way into capacity they can’t build fast enough. The risk is the usual one for roll-ups: paying top dollar at the peak, then integrating crews and cultures without losing the people who made the target worth buying.
