MDU Resources Group Narrows Earnings Guidance Amid Ongoing Utility Customer Growth and Capital Investment Plans.

MDU Resources Group reported Q3 2025 results with sales of $315.1 million and basic earnings per share of $0.09. The company narrowed its full-year earnings guidance to $0.90-$0.95 per share, citing ongoing utility customer growth and successful capital investment plans. The narrowed guidance reflects near-term operational execution as the most important short-term catalyst, while rising operating costs remain a prominent risk. Investors should be aware of persistently rising operation and maintenance expenses, which could significantly impact earnings.
