MasTec Inc. (NYSE: MTZ) entered a definitive agreement to acquire The Superior Group for approximately $1.65 billion, doubling its electrical infrastructure capacity in the data center vertical. Superior Group specializes in mission-critical electrical systems—the high-voltage backbone required for GPU clusters that consume 30 to 80 megawatts per facility. The deal closes MasTec's exposure gap in a market where electrical build-out has become the primary bottleneck for AI deployment, not rack space or cooling.
Superior Group generated roughly $1.2 billion in revenue over the trailing twelve months, with backlog concentrated in hyperscaler projects across Virginia, Texas, and the Pacific Northwest. The acquisition brings MasTec 2,400 additional electricians and engineers, along with established relationships with utilities managing interconnection queues that now stretch 18 to 36 months in key markets. MasTec paid approximately 1.4x revenue, a modest multiple given that electrical contractors with data center expertise have traded closer to 2.0x in private transactions over the past eighteen months. The deal is structured as cash and assumes $200 million in net debt.
The timing reflects a structural shift in infrastructure spending. Hyperscalers have committed over $200 billion in capital expenditures for 2025, with electrical infrastructure representing 30 to 40 percent of total project costs—higher than historical averages due to power density requirements for training clusters. MasTec's existing Communications segment, which served 5G and fiber deployments, faced decelerating growth as telecom operators pulled back. Superior's backlog provides immediate revenue visibility and repositions MasTec toward a customer base with multi-year capital allocation plans that are less cyclical than traditional telecom or oil-and-gas infrastructure.
The acquisition also addresses a labor constraint that has emerged as the binding constraint in data center construction. Skilled electricians capable of handling 480-volt and above systems are in short supply, and training cycles run 18 to 24 months. By acquiring a workforce already credentialed and deployed, MasTec avoids the ramp-up period that has delayed competitor bids. Superior's project pipeline includes work with utilities on substation upgrades required to support new data center interconnections, a secondary revenue stream that extends beyond the initial facility build-out.
Allocators should monitor MasTec's integration execution over the next two quarters, particularly whether Superior's backlog converts without customer concentration risk—if more than 40 percent of revenue derives from a single hyperscaler, pricing power diminishes. Watch for MasTec's guidance on incremental margin profile; electrical work typically carries 8 to 12 percent EBITDA margins, tighter than MasTec's legacy oil-and-gas segment but more stable. The company's ability to cross-sell MasTec's civil and mechanical capabilities into Superior's customer base will determine whether the deal generates strategic value beyond financial consolidation. Finally, track whether MasTec uses Superior's platform to enter the renewable interconnection market, where similar electrical expertise applies to battery storage and solar projects facing the same utility queue delays.
The transaction closes a capability gap that mattered more six months ago than six months from now. MasTec secured workforce and backlog at a moment when the hyperscaler build-out cycle remains visible through 2027, and before electrical contractors with data center exposure become acquisition targets for private equity infrastructure funds. The deal's success hinges on whether MasTec can retain Superior's engineering talent and avoid the margin dilution that typically follows large workforce integrations. The first test arrives in Q2 earnings, when investors will scrutinize whether Superior's backlog converts at the margins MasTec modeled, or whether labor inflation and project delays compress returns. The electrical bottleneck persists; MasTec now owns a larger share of the solution.
