COLUMBUS, Ind. -- Cummins Inc. has announced that the sale of its exhaust business to Global Tube, a portfolio company of Wind Point Partners, a private equity firm headquartered in Chicago, Ill., has closed.

The sale was announced earlier this year and includes what were formerly Cummins exhaust operations in Stoughton, Arcadia, Black River Falls and Viroqua, all in Wisconsin, and in Scoresby, Australia and Daman, India.

The exhaust business was a small part of Cummins Emission Solutions (CES), which is within the company’s Components operating segment. CES specializes in providing a range of aftertreatment solutions and technologies to control emissions in diesel engines. The exhaust business was not a core part of the aftertreatment business, Cummins said.

The company added that this sale allows CES to place greater emphasis and resources on products that are a critical part of Cummins’ growth strategy. As global emission standards become ever tighter, CES has opportunities for significant growth in developing and deploying aftertreatment systems for commercial vehicles.

Terms of the sale were not disclosed.
