MasTec Buys Superior Group to Boost Data Center Power Play
MasTec acquires century-old electrical contractor Superior Group to expand its critical infrastructure and data center capabilities.
MasTec (NYSE: MTZ) just pulled the trigger on a deal that signals exactly where the smart infrastructure money is flowing. The Coral Gables-based construction giant announced a definitive agreement to acquire Electrical Specialists, Inc. — operating as The Superior Group — a full-service electrical contractor laser-focused on critical infrastructure. This is a direct bet on the data center buildout boom, and MasTec isn't being shy about it.
Superior isn't some scrappy startup. The Columbus, Ohio-based firm has roots going back to 1925, making it one of the oldest specialty electrical contractors in the country. The Stewart family has run the operation since the mid-1980s, when Greg Stewart first took an ownership stake. That kind of institutional knowledge in mission-critical electrical work doesn't come around often — and MasTec knows it.

For MTZ shareholders, this acquisition sharpens the company's edge in two of the hottest infrastructure verticals right now: data centers and mission-critical facilities. AI-driven demand for power-hungry computing infrastructure has every serious contractor scrambling for qualified electrical capacity. MasTec just bought a proven one with a century of credibility behind it.
The strategic logic here is tight. MasTec already operates across telecom, clean energy, and heavy civil construction. Adding Superior's specialized electrical muscle — particularly in high-demand end markets — gives MTZ a more complete offering for hyperscaler and enterprise clients who need turnkey solutions. Watch this name if data center infrastructure stays hot, because MasTec is clearly positioning itself to win big contracts in that space.
