Centuri Holdings, Inc.
A North American utility and energy infrastructure services company that builds, maintains, and modernizes the electric and natural gas networks that deliver power to homes and businesses across the US and Canada. Its roots reach back to 1909, when the Riggs-Linthicum Company was founded, and the modern Centuri name was created in 2014 as a play on "century"—a nod to a hundred-year vision for energy infrastructure. Once part of Southwest Gas, the company went public in 2024.
