Riverside Turns Up the Heat to Acquire Monessen Hearth Systems

New Platform Adds Spark to Leveraged Buyout Firm’s Portfolio

New York, NY; Cleveland, OH; Dallas, TX and San Francisco, CA – The Riverside Company, the largest private equity firm investing in premier companies at the smaller end of the middle market, has landed a “hot” commodity – Monessen Hearth Systems (“MHS”), a rapidly growing manufacturer of a broad line of gas, wood, and electric hearth products and accessories primarily aimed at the home remodeling segment of the hearth industry. One of the fastest-growing companies in the fragmented, $1.6 billion hearth industry, Monessen has distinguished itself through quality products, expertise in the design and introduction of new products, and strong relationships with its customer base and distribution network. The Company enters Riverside’s portfolio as a new platform investment in the private equity firm’s 2003 fund, making it Riverside’s 127th investment since the firm’s founding in 1988.
Since 1993, when Monessen offered a limited line of gas logs, the Company has grown organically and through complementary acquisitions to become one of the largest hearth manufacturers in the U.S. MHS now designs and manufactures a full line of gas, wood, and electric fireplaces, stoves, gas logs, and accessories, with more than 20 new products or upgrades expected this year. The Company’s customers include both wholesale distributors and specialty hearth dealers serving the remodeling aftermarket, as well as distributors who focus specifically on installation and the new home construction market. “We were attracted to Monessen for a lot of reasons – especially its superior management team, impressive track record of growth through new product introductions and geographic expansion, and solid customer relationships,” noted Tim Gosline, the Riverside Partner who led this transaction. “In addition, the Company’s growth has consistently outpaced that of the overall hearth industry, and we have some ideas how to enhance its growth and market share.”

“Teaming with Riverside gives us access to additional resources necessary for continued growth,” said Bill Tweardy, President and CEO of MHS. “The size of the hearth industry, along with its fragmented nature, provides numerous opportunities for add-on investments. Riverside and its financing partners will provide the capital needed to execute upon our aggressive acquisition strategy. Plus, we’ll be able to tap into Riverside’s operating and business partner resources. It’s truly a great partnership.” Working with Gosline on the acquisition were Chris Jones – Vice President, and Sarah Roth – Associate. Senior debt for the transaction was provided by KeyBank, as agent, and Fifth Third Bank. Subordinated debt was provided by Babson Capital Management. Monessen marks Riverside’s sixth acquisition of 2006.
