Southwest Gas Holdings, Inc. is a long-standing natural gas distribution company with roots dating back to 1931, when it was founded to bring reliable energy to communities across the American Southwest. Headquartered in Las Vegas, Nevada, the company grew alongside the region’s rapid urban and industrial expansion, steadily extending its service territory through Arizona, Nevada, and California. Over the decades, Southwest Gas has established itself as a critical infrastructure provider, supplying natural gas to millions of residential, commercial, and industrial customers across some of the nation’s fastest-growing markets.
The company operates primarily through two core business segments: Natural Gas Distribution and Utility Infrastructure Services. Its Natural Gas Distribution segment delivers natural gas safely and efficiently through an extensive pipeline network spanning thousands of miles, supported by advanced monitoring systems and strong regulatory compliance. The Utility Infrastructure Services division, conducted through its subsidiary Centuri Group, provides construction, maintenance, and repair services to utilities across North America. This dual structure allows Southwest Gas to balance stable utility income with growth-oriented infrastructure operations that serve the broader energy delivery industry.
Southwest Gas’s operations emphasize system reliability, customer service, and long-term capital investment in its utility network. The company focuses on upgrading pipeline systems, expanding into new communities, and improving operational efficiency through technology-driven programs. Its infrastructure subsidiary, Centuri, complements these efforts by supporting underground utility projects, including gas, electric, and renewable energy connections, across diverse markets in the United States and Canada. This integrated approach gives the company both a steady regulated base and a platform for expansion in utility services.
