MDU Resources Group, Inc. reported stronger Q2 2026 results as a regulated electric, natural gas distribution and pipeline company. Operating revenues were $375.3 million versus $351.2 million a year earlier, with net income of $21.2 million and diluted EPS of $0.10 versus $13.8 million and $0.07. For the first six months, revenues were $981.3 million versus $1,026.0 million, while net income rose to $102.1 million and diluted EPS to $0.49 from $95.7 million and $0.47. Segment results reflected higher earnings from the electric business, a reduced seasonal loss in natural gas distribution, and modestly lower pipeline earnings mainly from lower other income and higher depreciation.
Total assets were $7.71 billion and stockholders’ equity $2.93 billion at June 30, 2026, with long‑term debt of $2.58 billion. Operating cash flow for the first half was $265.3 million, funding $193.5 million of capital expenditures. The company continued to access capital markets, issuing 1.3 million shares via its at‑the‑market program for $29.6 million and settling 4.3 million forward sale agreement shares for $81.3 million, with 7.4 million FSA shares still available. Pending regulatory proceedings include a North Dakota electric rate case seeking $34.5 million of annual revenue and a FERC pipeline case seeking $31.0 million.
MDU Resources Group reported stronger results for the quarter ended June 30, 2026, with consolidated net income of $21.3 million, up 55.5% from $13.7 million a year earlier, and diluted EPS of $0.10, up 42.9%. Operating revenues rose to $375.2 million from $351.2 million. For the first six months, net income was $102.1 million and diluted EPS $0.49. The electric utility segment’s quarterly net income increased to $14.7 million from $10.4 million, driven by Badger Wind Farm recovery, new rates in Montana and Wyoming, and higher retail volumes, including data center demand. The natural gas distribution segment reduced its seasonal loss to $3.9 million from $7.4 million, benefiting from new rates and volume growth.
The pipeline segment earned $14.4 million, down from $15.4 million, as higher depreciation and lower other income offset stronger transportation demand. MDU continues to advance the proposed Bakken East Pipeline Project, designed for 1.4 billion cubic feet per day of capacity, with precedent agreements totaling nearly 1.2 billion cubic feet per day and an expected project cost of $2.7–$3.2 billion. A FERC Section 7(c) application is anticipated in the fourth quarter of 2026, with targeted in‑service dates in late 2029 and late 2030. Across its jurisdictions, the company is pursuing multiple electric and natural gas rate cases. Management reaffirmed 2026 earnings guidance of $0.93 to $1.00 per share and a long‑term EPS growth objective of 6% to 8%.
