MasTec Closes $1.65 Billion Buy of Superior Group to Chase Grid-Buildout Work

MasTec Inc. closed its acquisition of Electrical Specialists Inc., operating as The Superior Group, on July 20 in a transaction valued at approximately $1.65 billion, according to a press release reviewed by Business Wire. The deal adds about 3,000 employees to MasTec's payroll and gives the NYSE-listed contractor a direct line into the high-voltage electrical work that grid modernization projects require.

The structure leans heavily on debt. According to the company's announcement on Business Wire, the purchase breaks down to roughly $1.175 billion in cash and $475 million in MasTec common stock, with a potential earnout tied to Superior's cumulative performance over 36 months post-closing. MasTec funded the cash piece through cash on hand, its existing revolving credit facility, and two delayed draw term loan facilities set up specifically for the deal.

The strategic logic, as management framed it, is about moving from what MasTec has called 'out-of-fence' infrastructure work, transmission lines and interconnection, into the 'in-fence' electrical systems inside data centers and industrial facilities. That's a meaningful product-mix shift. Superior, headquartered in Columbus, Ohio, and operating since 1925, has built its business on exactly those complex, large-scale interior electrical projects.

MasTec's forward guidance is aggressive. According to the company's July 7 announcement filed on Business Wire, management expects Superior to contribute $800 million to $900 million in revenue for the remainder of 2026, with adjusted EBITDA in the $100 million to $115 million range. For full-year 2027, the company is projecting $2.2 billion to $2.5 billion in Superior revenue and $250 million to $275 million in adjusted EBITDA. MasTec's own note that 'these estimates are preliminary' and that it 'has therefore taken a conservative approach to its outlook' is worth keeping in the file. Preliminary guidance stated at deal announcement tends to carry the rosiest assumptions, not the stress-tested ones.

The deal fits the broader infrastructure consolidation pattern that's been visible all year. Grid modernization across North America, driven by federal clean energy funding and industrial electrification, requires contractors with both workforce scale and specialized equipment that organic hiring alone can't assemble fast enough, according to an analysis published by MarketScale. Large contractors are buying regional specialists precisely because federal procurement offices increasingly want proof of capacity before awarding major contracts.

At $1.65 billion, the price tags MasTec, which carried a market cap of roughly $26.3 billion at close per Investing.com, as a willing buyer at a moment when electrical contractor valuations reflect the demand surge. MasTec's trailing price-to-earnings ratio stood at 62.85 going into the deal, well above its five-year median of 53.16, according to data cited by GuruFocus.

For MasTec shareholders, the math that matters is whether Superior can actually hit those 2027 revenue targets. At $2.2 billion to $2.5 billion, that would represent a run rate roughly triple what the company is expected to contribute in the back half of this year alone. That kind of ramp requires both project wins and execution, and infrastructure projects have a reliable habit of slipping schedules.
