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.
Natural gas distribution margin rose 8.7% on California rate relief, but net income fell as higher taxes and depreciation offset the gain.
Rate relief continued to lift the utility's core earnings, but it was not enough to grow the this quarter. Natural gas distribution rose 8.7% to $319.7 million, driven by approximately $19.5 million from updated California rates, yet net income fell 10.7% to $40.8 million as higher income tax expense and more than offset the gain. The company is now a pure-play regulated utility with a $1.7 billion expansion project on the horizon, but rising costs are eroding the benefit of new rates before they reach the bottom line.
