Tenneco Inc. (“Tenneco” or “the Company”) was formed under the laws of Delaware in 1996. Tenneco designs, manufactures, markets, and sells products and services for light vehicle, commercial truck, off-highway, industrial, and aftermarket customers. The Company is one of the world’s leading manufacturers of innovative clean air, powertrain, and ride performance products and systems, and serves both original equipment manufacturers (“OEM”) and replacement markets worldwide.

On January 10, 2019, the Company completed the acquisition of a 90.5% ownership interest in Öhlins Intressenter AB (“Öhlins”, the “Öhlins Acquisition”), a Swedish technology company that develops premium suspension systems and components for the automotive and motorsport industries.

Effective October 1, 2018, the Company completed the acquisition of Federal-Mogul LLC (“Federal-Mogul”) (the “Federal-Mogul Acquisition”, and together with the Öhlins Acquisition, the “Acquisitions”), a global supplier of technology and innovation in vehicle and industrial products for fuel economy, emissions reductions, and safety systems. Federal-Mogul serves the world’s foremost OEM and servicers (“OES”, and together with OEM, “OE”) of automotive, light, medium and heavy-duty commercial vehicles, off road, agricultural, marine, rail, aerospace, and power generation and industrial equipment, as well as the worldwide aftermarket. Following the closing of the Federal-Mogul Acquisition, the Company agreed to use its reasonable best efforts to pursue the separation of the combined company to form two new, independent, publicly traded companies, a new Powertrain Technology company (“New Tenneco”) and an Aftermarket and Ride Performance company (“DRiV”).
