Rosemont, Illinois-based middle-market private equity firm Wynnchurch Capital has sold its majority interest in Rosboro Holdings, Inc. to One Equity Partners but will continue to own a “significant” minority stake in the company, Wynnchurch announced.

Rosboro is a Springfield, Oregon-based manufacturer of engineered wood products, including stock and custom glued laminated timber and lumber used in residential and light commercial construction end markets.

After Wynnchurch invested in the company in 2016, Rosboro separated from its captive timberlands, completed an acquisition of Western Structures, built out its sales force and “made investments to improve operations and grow its glulam product offerings,” Wynnchurch said.

“Rosboro represented an opportunity to invest in a company with a leading market position, differentiated product offering and long-standing customer relationships,” Wynnchurch Partner Brian Crumbaugh said. “We are proud of the management team’s accomplishments during our ownership period and are excited to continue our partnership with management during Rosboro’s next phase of growth.”

Houlihan Lokey Capital, Inc. and Perkins Coie LLP served as financial advisor and legal counsel to Rosboro and Wynnchurch, respectively.
