Graybar has agreed to acquire Samson Electrical Supply of South Plainfield, New Jersey, marking the St. Louis-based distributor's third bolt-on deal of 2026 and its second in roughly five months.

The transaction, announced July 20, is expected to close in early August. Financial terms were not disclosed. Graybar previously acquired Broken Arrow Electric Supply in March and American Electric Supply in May, pointing to an unusually active M&A cadence for the 355-plus-facility distributor.

Samson Electrical Supply, founded in 1949, runs a full-service electrical distribution operation serving commercial, industrial, residential, institutional and utility customers in central New Jersey. The company supplies lighting, power distribution equipment, and a stock of MRO SKUs to a contractor and institutional base that regional independents have long defended against national accounts.

What does Graybar gain in New Jersey?

The Samson footprint gives Graybar counter, lighting and institutional share position in central New Jersey, an end market the national distribution channel has contested for years. Holding the business under its legacy name — and keeping its team, supplier contracts and customer book intact — lets the buyer collect local share without the attrition risk that typically follows a rebrand.

Chairman, president and CEO Kathleen M. Mazzarella framed the deal in customer terms. "Samson Electrical Supply is a highly regarded company with a strong customer focus and deep roots in New Jersey," she said. "This acquisition expands Graybar's presence in the region and enhances our ability to serve customers."

Samson President Michael Cohen cast the move as continuity for the seller. "Samson and Graybar share a long-term commitment to our customers, employees and suppliers," Cohen said. "Joining Graybar allows us to preserve the values that have defined Samson for generations while providing access to additional resources, capabilities and growth opportunities."

What the subsidiary structure preserves

Graybar's decision to keep Samson operating as a named subsidiary does specific work on the operating-margin side. It holds contractor relationships that drive counter pull-through, where independent wholesalers typically carry higher gross margin than national-account bids. It protects the lighting and lighting-controls franchise that has anchored Samson's architect and design-build business. And it shields any utility-side book of business that would be costly to re-bid under a new banner.

On the network side, the deal adds inventory depth in central New Jersey and a closer-to-customer stocking point for contractor classes that prioritize same-day fill rates. Regional electrical wholesalers run notoriously thin inventory turns; folding a regional counter into a national platform typically accelerates velocity without requiring local repricing.

The 2026 M&A cadence

Three deals in five months is a step-change from Graybar's historical pace. The two prior 2026 acquisitions — Broken Arrow Electric Supply and American Electric Supply — match the pattern of long-tenured regional consolidators in geographies where Graybar already had a footprint but lacked density. Samson fits that model.

The strategic frame is straightforward. National electrical distribution has narrowed to a handful of platforms. Each tuck-in shaves fixed cost out of overlapping logistics, lifts manufacturer rebate volume, and widens the share of wallet inside an existing contractor base.

No purchase multiple, no revenue figure, and no integration timeline were disclosed. That silence is standard for closely held regional distributors, and Samson — 77 years in business — has never filed public financials.

If Graybar closes the deal on schedule and retains Samson's counter base, the move tightens the company's grip on a state where national electrical distribution remains actively contested. Watch for the next regional target on Graybar's pipeline and for any post-close signal on combined revenue or inventory turns at the subsidiary level.
