MasTec Acquires Superior Group in $1.65B Cash-Stock Deal

MasTec, one of the largest infrastructure construction and engineering firms in the United States, has agreed to acquire The Superior Group in a deal valued at approximately $1.65 billion, to be funded through a combination of cash and stock.

The all-in valuation of $1.65 billion places this among the more significant acquisitions in the infrastructure services sector in recent memory.

Whether driven by grid modernization, broadband expansion, or clean energy deployment, the pipeline of complex, capital-intensive projects favors firms with national scale, diversified capabilities, and deep labor pools — all areas where acquisitions offer a faster path than organic growth alone.
