Electrical Contracting M&A
Cornerstone advises owners of electrical contracting companies on selling their business, from commercial and industrial contractors to low voltage, life safety and solar installers. Each sale process we run averages 8 to 10 indications of interest (offers).
A Real Market Analysis (RMA) is our market-based valuation. It shows what your company is worth in today’s M&A market, why, and what could make it worth more.
Buyers are competing for electrical contractors
Public consolidators
Quanta Services, EMCOR, and Comfort Systems USA are each buying electrical contractors. EMCOR bought Miller Electric, and Quanta bought Phalcon, a Farmington, Connecticut electrical contractor. MasTec agreed to buy The Superior Group, an electrical contractor focused on data center and mission critical work, for $1.65 billion.
Private equity and mechanical contractors
Private equity firms are funding regional electrical platforms and adding contractors to them. Mechanical contractors are buying electrical contractors so they can offer both trades.
Data centers and beyond
Data centers drive much of the demand. McKinsey projects that global demand for data center capacity could roughly triple by the end of the decade. On an EMCOR earnings call, CEO Tony Guzzi said EMCOR would rather buy a strong industrial or healthcare electrical contractor and grow it into data centers than pay a premium for a company doing 80% of its work in data centers.

What buyers pay for in an electrical contractor
Licensed crews
Journeymen, apprentices, and the training pipeline behind them. Buyers ask how many electricians will stay after the sale.
Service revenue
Service calls and maintenance agreements repeat every year, so buyers value them above one-time project revenue.
End markets
Data center, healthcare, and industrial customers draw more buyers than work tied to housing starts.
Customer mix
No single customer or general contractor should carry the business.
Backlog and WIP
Signed backlog at healthy margins, and a WIP schedule that ties to the financial statements.
Margins and growth
EBITDA margin and steady growth set the starting point for price.
Management
A team that can run jobs, bid work, and manage customers after the owner steps back.

Questions owners ask
Answers to common questions about selling an electrical contracting business.
What is my electrical contracting business worth?
It depends on your EBITDA, how much of your revenue comes from service and maintenance work, your end markets, customer concentration, and the quality of your backlog. Our Real Market Analysis (RMA) compares your company with similar sales and with public electrical contractors. Most RMAs are completed in three to four weeks.
Who buys electrical contracting companies?
National consolidators such as Quanta Services, EMCOR, and Comfort Systems USA; private equity firms building regional electrical platforms; mechanical contractors adding electrical; regional electrical contractors entering new markets; and family offices.
How long does it take to sell an electrical contracting business?
Our sell-side engagements close in 6 to 8 months on average, compared with about 11 months for the industry. Our Assurance 360™ process covers preparation, buyer outreach and meetings, the letter of intent, due diligence, and closing.
How do backlog and WIP affect the sale?
Buyers test both closely. They check that signed backlog carries healthy margins and that your WIP schedule ties to your financial statements. Overbillings and underbillings also affect the working capital target in the purchase agreement. Clean WIP reporting before going to market protects the price.
We are a union contractor. Does that change the sale?
It changes the buyer list and the diligence. Some buyers run union operations and some do not. Buyers review your collective bargaining agreements and any multiemployer pension obligations, which can affect how a deal is structured. We plan for this before going to market.
I received an unsolicited offer. What should I do?
Do not negotiate one-on-one before you know what the business is worth and who else would buy it. A Real Market Analysis gives you the number, and a competitive process shows whether the offer is the best one available.
Will my employees keep their jobs?
Most buyers in this trade are paying for your electricians and project managers, and they want to keep them. We screen buyers for fit, and retention and transition terms are part of the negotiation.
Can I keep a stake in the business after the sale?
Often, yes. Many private equity buyers offer an equity rollover, where you reinvest part of the proceeds in the larger company and share in its next sale.
What size electrical contractors does Cornerstone work with?
Electrical contractors with $5M to $250M in revenue and $1M to $25M in EBITDA, across the United States and internationally through the Cornerstone International Alliance.
