BISMARCK, N.D., Nov. 17, 2022 /PRNewswire/ -- The Board of Directors of MDU Resources Group, Inc. (NYSE: MDU) today announced that Brian R. Gray has been named president of the company's wholly owned construction materials subsidiary, Knife River Corporation, effective Jan. 1, 2023. David C.

Barney has 36 years of experience with Knife River in various leadership positions. He has been president of the company since 2011 and CEO since 2013.

Gray has 29 years of experience with Knife River and has been president of Knife River's Northwest Region since 2012. Since 2018, he has led seven acquisitions in the region, most recently the addition of Baker Rock Resources in the Portland Metro market.

"Brian has a strategic mindset that has driven strong growth in Knife River's Northwest Region," said David L. Goodin, president and CEO of MDU Resources.
