New York, NY – Kinderhook Industries, LLC (“Kinderhook”) is pleased to announce the sale of Copperweld Holdings, Inc. (“Copperweld,” or the “Company”) to investment funds affiliated with Rhône, a global private equity firm with a focus on investments in businesses with a transatlantic presence.  During its ownership, Kinderhook grew Copperweld’s EBITDA by approximately 650%, driven by strong organic growth and the successful completion of four add-on acquisitions.

Copperweld is the leading supplier of bimetallic wiring products and the only U.S. manufacturer of copper-clad steel (CCS) and copper-clad aluminum (CCA) wire. Combining reduced weight, enhanced durability, theft deterrence, and cost efficiency, Copperweld’s CCS and CCA products have secured their position as an alternative to traditional copper wiring. The company serves key electrification markets, including building wire, utilities, infrastructure, renewable energy, and mobile technology. Headquartered in Fayetteville, Tennessee, Copperweld also operates facilities in Texas and the United Kingdom.

“Kinderhook’s support for our ambitious growth strategy allowed Copperweld to strengthen our leadership position as the only U.S. manufacturer of CCS and CCA wire,” said Craig York, Chief Executive Officer of Copperweld. “Together, we disrupted the residential building wire market by providing homebuilders with a lighter, more durable, and cost-efficient alternative to traditional copper wire. With Rhône’s backing, we are excited to continue driving innovation and expanding our role in the electrification of infrastructure, renewable energy, and mobile technology.”

“We are incredibly proud of Copperweld’s transformation under our ownership,” said Paul Cifelli, Managing Director at Kinderhook. “Craig and his team executed on a bold vision and grew EBITDA more than sixfold by expanding capacity, closing four acquisitions, and capturing market share from traditional copper. Copperweld is now firmly established as the clear leader in bimetallic wiring products.”

“Copperweld exemplifies Kinderhook’s investment philosophy in action: partnering with outstanding management teams to scale businesses through organic growth and strategic M&A,” said Nate Druckenmiller, Principal at Kinderhook. “Beyond its financial success, Copperweld has fundamentally reshaped the residential building wire market by bringing innovation, reliability, and cost-efficiency to an industry long dominated by copper. That disruption, and the platform we’ve helped build, position Copperweld for continued market leadership and growth.

“This successful outcome is the result of close collaboration between Kinderhook, Copperweld, and our lending partners,” added Joe Mayer, Vice President at Kinderhook. “We are thrilled to have helped position Copperweld as a market leader and look forward to watching the Company’s continued success with Rhône.”

Kirkland & Ellis LLP is serving as legal counsel and Lincoln International served as financial advisor to Copperweld in the transaction.
