Infrastructure giant MasTec announced this week it will acquire The Superior Group, a national electrical contractor specializing in data centers, for $1.65 billion in a cash-and-stock deal that positions the company at the forefront of America's AI infrastructure buildout.

The acquisition marks one of the largest deals of the year in the data center construction space, reflecting surging demand for the facilities that power artificial intelligence workloads. Superior Group is expected to generate $1.6 billion in revenue in 2026, with data center projects representing the bulk of its business.

The AI Infrastructure Gold Rush

The deal comes as Big Tech companies pour unprecedented capital into AI infrastructure. According to recent industry estimates, Amazon, Google, Meta, and Microsoft are collectively investing approximately $650 billion in AI infrastructure in 2026 alone—a staggering sum that has created massive demand for contractors capable of building and electrifying data centers at scale.

MasTec, headquartered in Coral Gables, Florida, has traditionally focused on telecommunications, energy, and utility infrastructure. The Superior acquisition dramatically expands its capabilities in the red-hot data center market, where capacity cannot be built fast enough to meet demand from AI model training and inference workloads.

Power Becomes the Critical Constraint

Industry analysts note that power availability has become the primary bottleneck for data center expansion. Global data center electricity consumption is projected to double between 2022 and 2026, according to the International Energy Agency, straining power grids and creating opportunities for contractors with electrical infrastructure expertise.

Superior Group's specialty in electrical systems and mission-critical infrastructure makes it particularly valuable in this environment. The company has developed expertise in the high-voltage electrical work required for AI data centers, which consume significantly more power than traditional computing facilities.

Wall Street Reacts with Caution

Despite the strategic rationale, MasTec shares fell nearly 6% following the announcement. Investors expressed concerns about the deal's price tag and integration challenges, with some analysts questioning whether the company is paying a premium at the peak of the data center boom.

The deal structure includes both cash and stock components, and MasTec will need to demonstrate that it can capture synergies while managing the integration of Superior's specialized workforce.

A Broader Infrastructure Transformation

The MasTec-Superior deal reflects a broader transformation in American infrastructure. The AI revolution has created a new class of essential projects—data centers requiring massive electrical capacity, network buildouts connecting facilities across the country, and generation assets to power it all.

Nvidia's annual revenue has soared nearly eight-fold since 2022, from $27 billion to $216 billion in 2025, with consensus estimates projecting another 62% growth to $350 billion in 2026. That chip demand translates directly into demand for physical infrastructure: the buildings, power systems, and cooling required to run the processors.

Competition Heats Up

MasTec is not alone in pursuing data center opportunities. Private equity firms have poured billions into the sector, while established construction and infrastructure companies race to build capabilities. The competition for skilled labor—electricians, project managers, and specialized engineers—has become intense.

For MasTec, the deal represents a bet that the AI infrastructure buildout is still in early innings. With hyperscalers showing no signs of slowing their investment pace and new entrants entering the AI arms race, demand for construction and electrical services appears durable—even if near-term market volatility has investors proceeding cautiously.
