Southwest Gas, an investor-owned utility based in Las Vegas, is set to demerge Centuri Group, an unregulated utility services platform. Financial terms were not disclosed. "We are proud of the businesses we have built and are excited by the opportunities for continued value creation made possible by the separation. Just as Riggs Distler opens up new avenues for growth for Centuri, the acquisition of MountainWest provides us with the scale to create value across our regulated operations by sharing best practices, instilling operational excellence and delivering efficiencies, while driving strong, rate-regulated earnings and cash flow. We look forward to this next chapter of growth for both Southwest Gas and Centuri as we seek to maximize value for our stockholders, deliver excellent service to our customers and create new opportunities for employees," John Hester, Southwest Gas President and CEO.
