Atmos Energy history

Amarillo Gas made a pipeline connection to the field in 1920.

In 1924, Southwestern Development Company acquired both Amarillo Oil and Amarillo Gas.

United Cities was founded in 1929 as a butane air manufacturer and distributor, operating plants in 17 cities.

1953: Southwestern's various gas distribution businesses are consolidated as Pioneer Natural Gas Company.

1954–80: Consolidation and Continued Expansion

Included in these was Trans State Tire Company, which Pioneer bought in 1969 and sold off a year and a half later.

Notably, after the energy crunch that started in 1971, Pioneer began bolstering its exploration operations, and over the next ten years, riding the oil boom, turned itself into a billion-dollar corporation.

In 1981, the company was incorporated and became a fully regulated natural-gas-only distributor.

In 1983, Energas, the natural gas distribution division of Pioneer, was spun off and became an independent, publicly held natural gas distribution company.

In October 1988, Energas changed its corporate name to Atmos Energy Corporation and its stock began trading on the New York Stock Exchange under the ticker symbol "ATO". Today, Atmos Energy employs approximately 4,800 people.

In 1993, it purchased the Greeley Gas Company, then privately owned by the Schlessman family.

In July of 1997, Atmos reached a major milestone when it acquired its millionth customer.
