Mason Wells announced the closing of the sale of LBW Holding Corp. (“L.B. White” or the “Company”) to Modine Manufacturing Company (“Modine”), headquartered in Racine, Wisconsin. L.B. White was a Mason Wells Buyout Fund IV, LP portfolio company.

“We are very proud of the success that L.B. White has achieved under our ownership,” said Jay Radtke, executive managing director of Mason Wells. “Since our acquisition in 2017, we successfully executed the value creation plan that we developed together with the management team. We invested in new equipment to increase capacity and position the business for future growth. We also completed the acquisitions of Reeves Supply Company, a leading provider of evaporative cooling and ventilation door products to the poultry market, as well as Rentquip USA, a leading electric heat provider. These acquisitions furthered the Company’s market leadership positions in agriculture and portable heat, respectively. We would like to sincerely thank Kevin Gagermeier, President & CEO, and the entire L.B. White team for their dedication and hard work during our time together. We wish them all the best as the business transitions to the new owners, Modine.”
