MDU Resources Appoints Two to Board of Directors

BISMARCK, N.D., Aug. 15, 2024 /PRNewswire/ -- MDU Resources Group, Inc. (NYSE: MDU) announced today that Michael S. Della Rocca and Marian M. Durkin have been appointed to the company's board of directors.

Della Rocca, during his 35-year career, held a number of executive positions within the engineering and construction industry, including as chief executive, Americas, of AECOM. He also was a partner in consulting firm McKinsey & Company, where he provided clients with strategic counsel on capital projects.

She also has prior experience as vice president, deputy general counsel and assistant secretary at United Airlines and as an attorney at law firm Briggs and Morgan, which later merged with Taft.

"Marian and Michael bring extensive, relevant experience to our board that will support our efforts to guide MDU Resources' strategic initiatives as the company becomes a pure-play regulated energy delivery business late this year when it spins off Everus Construction Group," said Dennis W. Johnson, chair of the board.

In addition to their general responsibilities on the board, Della Rocca will serve on the Audit and the Environmental and Sustainability committees and Durkin will serve on the Compensation and the Nominating and Governance committees.

Durkin holds a Juris Doctor and Master of Laws from Mitchell Hamlin School of Law and a bachelor's degree in political science from Manhattanville College. She is a member of the state bar in Illinois, Minnesota and Washington.

MDU Resources expects to achieve its objective of becoming a pure-play regulated energy delivery business by completing a spinoff of its construction services subsidiary, Everus Construction Group, late this year.
