It expanded into natural gas in 1927; in 1935 its subsidiaries were consolidated under Montana-Dakota Utilities Co. The company entered coal mining in 1945, listed on the New York Stock Exchange in 1948, and adopted the name MDU Resources Group, Inc. in 1985. [https://www.mdu.com/about-us/][https://www.mdu.com/100th-anniversary/]\n\nThe company broadened beyond utilities in the 1990s: an aggregate-company acquisition in 1992 marked its entry into construction materials, and it began a construction-services business in 1997. It expanded its natural-gas distribution operations by completing the Cascade Natural Gas acquisition in 2007 and the Intermountain Gas acquisition in 2008.

In 2024, it completed the spin-off of its construction-services business as Everus Construction Group.
