# Tenneco

Tenneco, Inc. (formerly Tenneco Automotive and originally Tennessee Gas Transmission Company) is an American automotive components original equipment manufacturer and an aftermarket ride control and emissions products manufacturer. It is a Fortune 500 company that was publicly traded on the New York Stock Exchange since November 1999 until it was taken private in November 2022 by Apollo Global Management. Tenneco is headquartered in Northville, Michigan.

## History

Tenneco's origin was in the Chicago Corporation, established about 1930. Tennessee Gas and Transmission Company (completely separate) had been formed in 1940.

### Natural gas

A shortage of fuel for World War II defense industries in the Appalachian area developed when industrial production was increased. The nuclear development operations of the Manhattan Project at Oak Ridge, Tennessee consumed huge quantities of Tennessee Valley Authority electrical power that would have otherwise been available to other industrial operations. The Chicago Corporation was able to acquire a Federal Power Commission (FPC) license to build a pipeline from Texas to Appalachia, eventually expanding to the largest natural gas pipeline network in the United States. These pipelines were acquired by El Paso Corporation in 1996, and are now owned by Kinder Morgan.

### Diversification

In the 1950s, the company acquired existing oil companies, including Sterling Oil, Del-Key Petroleum, and Bay Petroleum. The Tennessee division of the Chicago Corporation acquired Tennessee Gas Transmission Company in 1943 to build a natural-gas pipeline 1,265 miles (2,036 km) from Texas to West Virginia. The first line was completed in October 1944. It was followed by three additional pipelines totaling 3,840 miles (6,180 km) during the next 15 years which provide gas to New York and New Jersey.
In 1966, Tennessee Gas was incorporated as Tenneco, Inc. Tenneco expanded into a number of business ventures as a result of diversification. In 1967, the company acquired Walker, Inc., a manufacturer of universal-fit exhaust mufflers and pipes. The year after, they started working on the construction of a universal-fit catalytic converter, that would become a cost-effective alternative to the OE catalytic converters. It took the company 8 years to introduce one. Tenneco bought Houston Oil & Minerals Corporation with two gold mines in Nevada in the late 1970s. Tenneco owned and operated a large number of gasoline service stations, but all were closed or replaced with other brands by the mid-1990s.
In the 1970s, Tenneco purchased 53% of J.I. Case when they purchased its owner Kern County Land Company, the agricultural equipment manufacturer based in Racine, Wisconsin, USA. In 1972, Tenneco purchased UK-based David Brown Tractors, and merged it with the J.I. Case business. In 1984, Case parent Tenneco bought selected assets of the International Harvester agriculture division and merged it with J.I. Case. All agriculture products are first labeled Case International and later Case IH. Tenneco purchased the articulated 4WD manufacturer Steiger Tractor in 1986, and merged it into Case IH.
The new corporate direction was to buy failing companies in a variety of industries, and then to develop them into profitable businesses. This worked well with Newport News Shipbuilding, but failed miserably with the various tractor companies, probably due in large part to the economy at the time. By 1988, the company was losing $2 million per day. After being pressured by the banks, it was decided to sell off the oil business. Tenneco Oil Exploration Company was split up and sold off to multiple buyers.
By 1994, Tenneco decided to begin getting out of the agricultural business and agreed to sell 35% of the now named Case Corporation. In 1996, the spin-off of Case Corporation was completed. The company was acquired by Fiat in 1999 and merged with New Holland Agriculture to form CNH Global.

### Consolidation

Tenneco Inc. emerged from a conglomerate consisting of six unrelated businesses: shipbuilding, packaging, farm and construction equipment, gas transmission, automotive, and chemicals. The automotive division was spun off from Tenneco, Inc. in 1991 along with the packaging, energy, natural gas, and shipbuilding divisions. All businesses except automotive and packaging were disposed of between 1994 and 1996 (through public offerings, sales, spin-offs and mergers). In 1999, Tenneco Packaging was spun off and renamed to Packaging Corporation of America and Pactiv Corporation.
Since the 1960s, Tenneco Automotive has sold mufflers (UK: silencers) in Europe, including through the Pit Stop chain in Germany. The group bought a German factory in Viernheim in 1969, Swedish Starla at Vittaryd in 1974, French Bellanger at Laval, English Harmo Industries, east of Birmingham, in 1976 and Danish Lydex at Middelfart in 1978. More acquisitions followed.
On October 28, 2005, Tenneco Automotive was renamed as Tenneco.

#### Federal Mogul and Öhlins acquisitions

On October 1, 2018, Tenneco completed its acquisition of Federal-Mogul, a large global supplier to original equipment manufacturers and the aftermarket. The following month, Tenneco bought a majority stake in Öhlins for $160 million.
In February 2019, Tenneco announced that it would spin off its automotive aftermarket suspension components into DRiV Incorporated.
In October 2024, Tenneco agreed to sell Öhlins to Brembo for $405 million.

#### Acquisition by Apollo Global Management

On February 23, 2022, Tenneco announced that it had entered into a definitive agreement to be acquired by Apollo Global Management for $7.1 billion. The acquisition was completed in November 2022.

## Controversy

During the 2022 Russian invasion of Ukraine, reports surfaced that Tenneco had failed to join other "international" (mainly western) businesses by withdrawing from the Russian market. Research from Yale University updated on April 28, 2022, identifying how companies were reacting to Russia's invasion identified Tenneco in the worst category of "Digging In", meaning Defying Demands for Exit: companies defying demands for exit/reduction of activities.
