ONE Gas

ONE Gas, Inc. is a publicly traded American natural-gas utility focused on regulated distribution services. The company was established as an independent business in February 2014, when ONEOK separated its natural-gas distribution operations into a standalone company. The separation created a utility whose business is centered on delivering natural gas through regulated local distribution networks rather than on exploration, production, or broad energy trading. The company operates through three principal utility businesses: Oklahoma Natural Gas, Kansas Gas Service, and Texas Gas Service. Together, these operations serve more than two million customers across Oklahoma, Kansas, and Texas. Its customer base includes residential households, commercial users, industrial customers, transportation users, and wholesale customers. The service territory is geographically broad but concentrated in selected regional networks: most of Oklahoma, much of the eastern half of Kansas, and several separate areas of Texas. ONE Gas has particularly substantial customer concentrations in the metropolitan areas of Oklahoma City and Tulsa; Kansas City, Wichita, and Topeka; and Austin and El Paso. By customer count, it is the largest natural-gas distributor in Oklahoma and Kansas and the third-largest in Texas. These positions give the company a regional rather than national operating profile, with its scale derived from long-established utility franchises and infrastructure in the central and southern United States. The business model is based on providing essential gas-delivery service under state regulatory oversight. This means that rates, service obligations, infrastructure investment, and other important aspects of operations are shaped by applicable public-utility regulation. ONE Gas therefore differs from an unregulated energy merchant: its principal offering is the reliable transportation and delivery of natural gas to connected customers within defined service territories. The company’s corporate history is linked to the original Oklahoma Natural Gas Company, founded in 1906. That utility heritage ultimately became part of the business that adopted the ONEOK name in 1980. The 2014 separation returned the distribution operations to a standalone publicly traded utility structure under the ONE Gas name. The resulting company retained the established operating brands and service networks while pursuing a focused identity as a regulated natural-gas distributor. ONE Gas’s positioning is consequently that of a regional infrastructure utility with a concentrated geographic footprint, a large recurring customer base, and operating companies rooted in long-running local gas businesses. Its scope is limited primarily to natural-gas distribution and associated customer services in its three states, rather than a diversified portfolio spanning electricity, oil production, or international energy markets.

ONE Gas is a modern corporate entity built on more than a century of natural-gas utility operations. The historical foundation of its business reaches back to the Oklahoma Natural Gas Company, which was established in 1906. That predecessor represents the long-standing local-utility heritage that continues to underpin ONE Gas’s operations in Oklahoma and, through the later development and organization of related utility businesses, its broader regional footprint. In 1980, the corporate organization associated with the original Oklahoma Natural Gas business adopted the ONEOK name. The ONEOK structure subsequently included natural-gas distribution operations serving multiple states. These distribution businesses operated as part of a larger energy company before being separated into a dedicated utility enterprise. In February 2014, ONEOK spun off its natural-gas distribution subsidiaries and created ONE Gas as a standalone, publicly traded company. The transaction separated the regulated distribution business from the rest of the parent organization’s energy activities. ONE Gas emerged with a focused utility profile and continued operating through three principal businesses: Oklahoma Natural Gas, Kansas Gas Service, and Texas Gas Service. The standalone company’s service territory covers most of Oklahoma, a substantial portion of eastern Kansas, and several distinct areas of Texas. Its customer markets include major urban areas such as Oklahoma City, Tulsa, Kansas City, Wichita, Topeka, Austin, and El Paso, as well as customers in surrounding communities and other parts of its regulated territories. The company serves multiple customer classes, including residential, commercial, industrial, transportation, and wholesale users. Since its formation, ONE Gas has been characterized by the concentration of its activities in regulated natural-gas distribution. The company’s scale is measured primarily by its customer connections and utility infrastructure rather than by international operations or upstream energy production. It is identified as the largest natural-gas distributor by customer count in Oklahoma and Kansas and the third-largest in Texas. Its present identity therefore combines the heritage of local gas utilities with the structure of a separately listed regional utility company.
