Stuart C. Irby Co., a subsidiary of Sonepar USA, has agreed to acquire Rigby Electric Supply Inc. (doing business as RE Supply).

RE Supply is an electric utility distributor operating out of Rocky Mount, N.C., that specializes in servicing municipalities, investor-owned and cooperative electric utilities within North Carolina, South Carolina, Virginia, Maryland and Delaware.

“RE Supply was attractive because of its position in the fast-growing Carolina and mid-Atlantic regions, its specialization in the technical-services area and its experienced and knowledgeable employees,” said Michael C. Wigton, president of Irby. “This important acquisition provides a unique opportunity for Irby to strengthen our position in the utility market and expand our existing utility product and service offering.”

Under the terms of the agreement, Irby will add one new location in North Carolina to its utility footprint.

“RE Supply is very excited about joining the Irby/Sonepar family. We will transition to operate and market ourselves under the Irby name,” said Rick Voltz, president of RE Supply.

Irby operates in four market segments — utility, commercial, contractor and industrial.
