MasTec Inc. shares rose 6% Wednesday after the company announced it will acquire electrical contractor The Superior Group for $1.65 billion in cash and equity. The deal eliminates MasTec's largest competitor for mission-critical electrical work inside AI data centers where power density requirements have doubled in eighteen months.

Superior generated $2.1 billion in trailing revenue across 4,200 active projects, with 68% of that work concentrated in hyperscale data-center electrical systems. The acquisition adds 11,000 electricians and engineers to MasTec's existing 32,000-person workforce and consolidates the two firms that together hold an estimated 41% share of North American data-center electrical contracting above 50 megawatts nameplate capacity. MasTec will fund the purchase with $950 million in new term debt, $400 million in equity issued to Superior's ownership group, and $300 million from its existing revolver.

The timing reflects infrastructure bottleneck economics. Nvidia-class GPU clusters require 40 to 80 kilowatts per rack versus 6 to 12 kilowatts in legacy enterprise IT environments. Electrical build-out has become the gating factor for data-center commissioning timelines, now stretching to 22 months from site acquisition to first rack online. MasTec's backlog grew 94% year-over-year to $12.3 billion as of Q4 2024, with $7.8 billion attributable to data-center and utility-scale power projects. Superior's order book extends 16 months forward at current burn rates, providing revenue visibility MasTec has not previously achieved in its communications infrastructure or clean energy segments.

The transaction also solves a labor arbitrage problem. Electrical contractors have been poaching IBEW-certified electricians at $58 to $72 per hour plus retention bonuses, compressing MasTec's gross margins on fixed-price contracts by 340 basis points since Q2 2023. Superior operates a vertically integrated apprenticeship program that graduates 1,100 electricians annually, reducing reliance on open-market hiring. Combined entity gross margins should stabilize near 11.2% by Q1 2026 as the firms rationalize duplicative site supervision and consolidate supplier agreements for switchgear and transformer procurement.

Allocators should track three forward indicators over the next six months: MasTec's success in retaining Superior's 190-person engineering leadership team, the company's ability to cross-sell fiber and mechanical systems into Superior's hyperscale customer base, and any regulatory friction from the FTC given the combined market share in electrical contracting above 100 megawatts. The Hart-Scott-Rodino filing occurred January 14; if no second request is issued by March 10, the deal closes in early April.

MasTec now holds option value on the only outcome worse than losing the AI infrastructure build-out: winning it without the specialized labor to execute at margin.
