SWX

Southwest Gas Holdings, Inc.

A regulated natural gas utility that delivers gas to homes and businesses across Arizona, Nevada, and California, serving more than two million customers. It began in 1931 in Barstow, California, when three founders started distributing butane and propane, then converted to natural gas in the 1950s as pipelines arrived. The company's headquarters moved to Las Vegas in 1958, and in 2025 it separated from its construction arm, Centuri, to focus purely on gas delivery.
