## Overview

Atmos Energy Corporation is a regulated natural-gas utility and energy infrastructure company. Its core businesses are distributing natural gas to customers and providing pipeline transportation and storage services. [1](https://app.finbar.com/go?id=P47500640) It serves residential, commercial, and industrial customers in eight U.S. states—Colorado, Kansas, Kentucky, Louisiana, Mississippi, Tennessee, Texas, and Virginia—and reported serving about 3.4 million customers in 1,400 communities in FY2025. [2](https://app.finbar.com/go?id=P82500717)[3](https://app.finbar.com/go?id=T4520580)

The company’s stated vision is to be “the safest provider of natural gas services.” [4](https://app.finbar.com/go?id=P76424757) Atmos reported FY2025 operating revenue of approximately $4.7 billion and described its workforce as nearly 5,500 employees in its 2026 corporate responsibility and sustainability report.

## Products & services

Atmos Energy’s customer-facing offering is regulated natural-gas sales and delivery to residential, commercial, industrial, and public-authority customers. It also transports natural gas for customers that use its distribution system without buying the gas from Atmos. [7](https://app.finbar.com/go?id=P147190814)

Through Atmos Pipeline–Texas (APT), the company provides pipeline transportation and storage to its own distribution divisions and third parties, including local distribution companies, industrial and electric-generation customers, marketers, and producers. Services include firm and interruptible transportation, storage, pooling, operational balancing, and parking and lending. APT operates approximately 5,700 miles of Texas transmission pipeline and five underground storage facilities. [8](https://app.finbar.com/go?id=P18071496)[9](https://app.finbar.com/go?id=P84535157)[1](https://app.finbar.com/go?id=P47500640)[10](https://www.atmosenergy.com/apt/apt-services-we-provide/)[11](https://www.atmosenergy.com/apt/about-atmos-pipeline-texas/)

For the nine months ended June 30, 2026, external-party operating revenue was $3.909 billion from distribution and $275.2 million from pipeline and storage—approximately 93.4% and 6.6%, respectively, of reportable-segment external revenue. These figures describe segment revenue mix, rather than a breakdown of product volumes. [12](https://app.finbar.com/go?id=T16840631)

## Geographic presence

Atmos Energy operates regulated natural-gas distribution businesses in Colorado, Kansas, Kentucky, Louisiana, Mississippi, Tennessee, Texas, and Virginia. The company reports approximately 3.4 million customers across its six distribution divisions. [13](https://app.finbar.com/go?id=P147190618) [14](https://www.atmosenergy.com/utility-operationsrates/utility-operations/)

Operations are concentrated in Texas, which accounted for approximately 75% of consolidated operations in the FY2025 filing; this is an operations measure, not a state-level revenue share. [15](https://app.finbar.com/go?id=P89018483) The company’s published territory information reports 2,146,423 customers in 630 Texas communities, with service areas including Dallas–Fort Worth, Lubbock, Amarillo, and the Permian Basin. Other reported territories include Mississippi (249,562 customers in 110 communities) and Colorado (130,890 customers in 65 communities). [16](https://www.atmosenergy.com/texas-service-territory/) [17](https://www.atmosenergy.com/mississippi-service-territory/) [18](https://atmosphere.atmosenergy.com/colorado-service-territory/)

Atmos Energy’s principal executive office is in Dallas, Texas. The company reports approximately 5,300 employees overall; published state figures include 2,735 in Texas, 344 in Mississippi, and 142 in Colorado.

## Business segments

Atmos Energy reports two business segments. The Distribution segment operates natural-gas distribution systems and passes gas costs through to customers under purchased-gas adjustment mechanisms; it generated approximately $4.425 billion, or 80.6% of gross segment revenue, in FY2025 [21](https://app.finbar.com/go?id=P72899887). The Pipeline and Storage segment provides natural-gas transportation and storage, principally through the APT system, and operates a Louisiana transmission pipeline; it generated approximately $1.065 billion, or 19.4% of gross segment revenue [21](https://app.finbar.com/go?id=P72899887).

These percentages are based on segment revenue before intersegment eliminations; consolidated operating revenue was lower after those eliminations. They represent revenue contribution, not operating-income contribution [21](https://app.finbar.com/go?id=P72899887).

## Company history

Atmos Energy traces its origins to 1906 in the Texas Panhandle. After developing through mergers into Pioneer Corporation, its Energas natural-gas distribution business was spun off as an independent company in 1983. In October 1988, Energas adopted the Atmos Energy name and began trading on the New York Stock Exchange as ATO. [20](https://www.atmosenergy.com/company/about-atmos-energy/)

The company expanded through a series of acquisitions and mergers: it acquired Greeley Gas in 1993, extending its operations into Colorado and Kansas; merged with United Cities Gas in 1997; acquired Mississippi Valley Gas in 2002; and completed its acquisition of TXU Gas’s distribution and pipeline operations in 2004.
