MasTec has agreed to acquire Superior Group for approximately $1.65 billion, adding roughly 3,000 employees and specialized electrical and infrastructure capacity aimed at data center construction, the company announced.
The consideration is about $1.175 billion in cash and $475 million in stock. This is an acquisition agreement β closing conditions had not been reported as satisfied at announcement, so the transaction should not yet be described as completed.
Key facts
- Transaction value: approximately $1.65 billion.
- Structure: about $1.175 billion cash and $475 million stock.
- Superior Group headcount: roughly 3,000 employees.
- Projected 2026 revenue: $1.6 billion to $1.7 billion.
- Status: an announced agreement, not a completed transaction.
The multiple says this is about labor, not earnings
At roughly $1.65 billion against projected revenue of $1.6 billion to $1.7 billion, MasTec is paying about one times revenue β an unremarkable multiple for a specialty contractor.
Divide differently and the logic sharpens: the price works out to roughly $550,000 per employee. For a construction services business, that is the number that explains the deal. MasTec is not buying a proprietary technology or a real estate portfolio. It is buying approximately 3,000 people who can build high-voltage electrical infrastructure, and the licenses, safety record and utility relationships that come with them.
Skilled electrical labor has become the genuine constraint in data center delivery. Capital is abundant, land is available in most markets, and equipment can be ordered. Crews qualified to install substations, switchgear and medium-voltage distribution at scale cannot be created on the timeline hyperscale developers require β apprenticeship pipelines take years.
Why the bottleneck moved downstream
Two years ago the binding constraint on data center development was power availability and interconnection queues, a dynamic examined in our analysis of how power demand is reshaping industrial markets.
Power remains the primary constraint, but a second one has emerged behind it: even with an approved interconnection, someone must actually build the electrical infrastructure. Contractors capable of that work are booked well in advance, and developers increasingly compete for construction capacity as directly as they compete for megawatts.
Vertical consolidation is the predictable response. When a scarce input determines schedule, buyers of that input eventually buy the supplier β which is what a $1.65 billion agreement for 3,000 electricians represents.
The risk is concentration in a single demand driver
The obvious caution is cyclicality. Superior Group’s value assumes data center construction continues at present intensity, and that demand traces back to AI infrastructure spending by a small number of very large technology companies.
That capital has proven willing to move. Projects can be cancelled outright, as Virginia demonstrated when QTS terminated its Prince William Digital Gateway plan, and jurisdictions are beginning to impose new costs β including Virginia’s new per-kilowatt-hour electricity tax. A contractor concentrated in this sector inherits that volatility.
What it means
For industrial developers, the practical implication is that construction capacity should be secured as early as land and power. Contractor availability is increasingly what sets delivery dates.
For owners and investors, contractor consolidation generally means firmer pricing. Fewer independent bidders for specialized electrical work reduces competitive tension on bids.
And for anyone underwriting data center development, the deal is a reminder to treat construction capacity as a real line item of project risk β not an assumption.
