One Equity Partners to Acquire Rosboro, a Leading Manufacturer of Sustainable Engineered Wood Products

OEP to Apply Industrial Expertise and Strategic M&A to Help Company Scale and Expand Market Reach

NEW YORK – One Equity Partners (“OEP”), a middle market private equity firm, today announced that it has acquired a majority interest in Rosboro from Wynnchurch Capital. Rosboro is a leading manufacturer of glued laminated timber (“glulam”), an engineered wood product used in a wide range of building and construction applications, and a variety of lumber products. Wynnchurch Capital will remain a significant minority shareholder. Financial terms of the private purchase were not disclosed.

Based in Springfield, Oregon, Rosboro operates captive sawmills and glulam production facilities allowing for the cost-effective production of stock, non-stock and custom glulam. Its products are sold through a well-established group of wholesale distributors and dealers throughout the United States to a diverse group of customers who rely on Rosboro for the industry’s highest quality glulam products and next-day availability. 

“Rosboro is an excellent business making high-quality differentiated engineered wood products at scale,” said Matthew Hughes, Managing Director at OEP. “Rosboro is poised to benefit from a number of growth drivers including single-family residential housing starts, net migration to the U.S. West, increasing residential repair and remodel, and glulam’s increasing share against structural wood alternatives and other engineered wood products. We look forward to working with CEO Rich Babcock and his team to capitalize on a growing market opportunity.”

“We are very excited for OEP to come on board as our partner,” said Babcock. “Their experience building industrial businesses like ours, as well as their strong relationships within the timber sector makes OEP an ideal partner as we pursue our next stage of growth. We are grateful to Wynnchurch for a great relationship over the past five years and the collaboration on several initiatives that have us well positioned for continued success.”

Brian Crumbaugh, Partner at Wynnchurch said, “We are exceptionally proud of the Rosboro team’s accomplishments over the past five years. The team has significantly scaled the business, established a salesforce to drive pull-through demand, and implemented best practices across every functional area of the Company. OEP brings global resources and significant experience supporting industrial businesses, which will help Rosboro to continue its growth as the market leader in glulam.” 

Glulam is a form of lumber created using small pieces of wood bonded together to create a larger piece of timber that would typically require the use of old growth timber. This product, sourced from sustainable forests that sequester carbon, directly supports the residential housing market and has applications to fast growing markets such as mass timber. The material is cost competitive and an alternative to traditional steel and concrete materials.
