Hudson Products Holdings, Inc. Completes the Acquisition of Smithco Engineering, Inc. and Metal Services, Inc.

Hudson Products Holdings, Inc. (Hudson), a global manufacturer of air-cooled heat exchangers and axial-flow fans, announced today that it has closed the acquisition of Smithco Engineering, Inc. and Metal Services, Inc., (collectively Smithco). The Sterling Group, L.P., a Houston-based private equity firm, is the majority owner of Hudson.

Smithco, based in Tulsa, Oklahoma, manufactures large-scale air-cooled heat exchangers. Products include both forced and induced-draft heat exchangers which are sold to customers such as oil refineries, gas processors, gas transmission pipelines, power generation plants, utilities and chemical processing plants. Smithco was previously owned by Judy Smith of Laguna Beach, California.

“I am pleased to welcome Smithco to the Hudson family,” said Chris Yunkun, CEO of Hudson. “The addition of Smithco broadens Hudson’s product offering and market presence. We look forward to working closely with Smithco’s management team to enhance both organizations’ performance in the air-cooled heat exchanger market.”

The acquisition was financed entirely with an extension of Hudson’s senior credit facilities. Concurrent with the acquisition, Hudson was able to more favorably re-price its senior credit facility. Debt financing for the transaction was led by BNP Paribas.
