History of Tenneco Inc.
Tenneco began in 1940 as Tennessee Gas and Transmission Company, a pipeline business that diversified through the conglomerate era into shipbuilding, packaging, chemicals, and automotive parts. The automotive business crystallized through the 1990s-2000s into a focused supplier of ride performance and clean air systems.
The modern company was reshaped by two big deals: the 2018 acquisition of Federal-Mogul for $5.4 billion, which brought the entire Motorparts aftermarket portfolio (MOOG, Fel-Pro, Champion, Wagner, National, Anco) plus powertrain components, and the planned-but-abandoned split into separate aftermarket and powertrain companies that was overtaken by the Apollo takeover.
Apollo's November 2022 go-private delisted Tenneco, and the company has since operated as a private equity portfolio company, continuing the DRiV Motorparts aftermarket strategy and supplying global OEM clean-air and powertrain programs.
