Solid performance in the pipeline segment driven by higher transportation revenue
Electric utility and natural gas distribution customer base achieves combined targeted growth rate at 1.4% year-over-year
Data centers drive higher electric retail sales volumes
2025 earnings guidance narrowed: $0.88 to $0.95 per share
Long-term EPS guidance remains unchanged with an expected growth rate of 6%-8%

BISMARCK, N.D., Aug. 7, 2025 /PRNewswire/ -- MDU Resources Group, Inc. (NYSE:MDU) today announced second quarter financial results for 2025, with sustained momentum in the pipeline segment and regulatory progress supporting the company's long-term value proposition as a pure-play regulated energy delivery business.

"We continued our solid start to 2025, despite weather and operating cost challenges that impacted the second quarter results," said Nicole A. Kivisto, president and CEO of MDU Resources. "We continue to invest in infrastructure, including customer driven growth projects at our pipeline, and advance prudent rate proceedings across multiple jurisdictions."

The following summarizes the company's results for the three and six months ended June 30, for 2024 and 2025:

	Three Months Ended June 30:		Six Months Ended June 30:
	2025	2024	2025	2024
	(In millions, except per share amounts)
Net income	$ 13.7	$ 60.4	$ 95.7	$ 161.3
Earnings per share, diluted	$ .07	$ .30	$ .47	$ .79
Income from continuing operations	$ 14.1	$ 20.2	$ 96.6	$ 95.0
Earnings per share from continuing operations, diluted	$ .07	$ .10	$ .47	$ .47
On Oct. 31, 2024, MDU Resources successfully completed the spinoff of Everus, which became an independent, publicly-traded company. Prior period results have been restated to reflect the spinoff. Everus' historical results of operations and certain costs associated with the spinoff are reported as discontinued operations.

"We've narrowed our full-year earnings guidance, reflecting our view midway through the year," Kivisto added. "Weather conditions and operation and maintenance expense impacted our second quarter results; however, we remain confident in our ability to execute on our long-term growth strategy. We believe our operational focus and financial discipline continue to position us well for delivering safe and reliable energy, customer value and strong stockholder returns."

Electric Utility Segment

Rate Relief and Higher Retail Sales Volumes Offset by Increased Operation and Maintenance Expense

Retail sales volumes increased 12.0%, driven by data center demand
Continued customer growth
Operation and maintenance costs increased due to higher payroll-related costs and a planned outage

The electric utility segment earned $10.4 million in the second quarter of 2025, compared to $15.5 million in the second quarter of 2024. Higher payroll-related costs and a net of tax expense of $1.6 million in second quarter of 2025 for a planned outage at Coyote Station, contributed to increased operation and maintenance expense. These were partially offset by increased commercial sales volumes—notably from data center load—and rate relief in South Dakota.

Electric Utility Regulatory Update:

North Dakota: Filed an application for Advanced Determination of Prudence and a Certificate of Public Convenience and Necessity for a 49% ownership interest in the Badger Wind Project, hearing is scheduled for Sept. 9, 2025
Wyoming: Filed a General Rate Case requesting a $7.5 million annual increase, anticipated to be effective May 1, 2026
Montana: An electric general rate case filing is planned for later this year

Natural Gas Distribution Segment

Regulatory Gains Offset by Increased Operation and Maintenance Expense and Unfavorable Weather

Increased operation and maintenance expense due to higher payroll-related expenses
Volumes declined due to warmer temperatures
Rate relief in Washington and Montana partially offset seasonal losses
Natural gas retail customer count increased 1.5% year-over-year

The natural gas distribution segment reported a seasonal second quarter loss of $7.4 million, compared to a $5.0 million loss in the same period last year, mainly due to higher operation and maintenance expense primarily related to increased payroll-related expenses. Warmer weather year-over-year was a key challenge—particularly in Idaho. The company benefited from newly implemented rates in Washington and interim rates in Montana, and transportation revenue growth.

Natural Gas Distribution Segment Regulatory Update:

Idaho: Filed a General Rate Case requesting $26.5 million annually with a requested effective date of Jan. 1, 2026
Montana: Filed a settlement agreement of $7.3 million annually, pending Montana Public Service Commission approval; interim rates in effect since Feb. 1, 2025
Washington: A revision to rates submitted on April 30, 2025, related to projects that were not placed in service, reducing revenue by $3.7 million, effective June 1, 2025
Wyoming: Reached a settlement agreement requesting $2.1 million annually, pending formal approval

Pipeline Segment

Growth Projects Offset by Increased Operation and Maintenance Expense and Absence of a Customer Settlement

Increased transportation revenue
Continued strong customer demand for short-term firm transportation capacity
Higher operation and maintenance expense due to payroll-related costs

The pipeline segment had a strong second quarter, with earnings of $15.4 million, demonstrating consistent year-over-year performance, absent proceeds of $1.5 million, net of tax, from a customer settlement in the second quarter of 2024. Recent expansion projects placed in-service, including the Wahpeton Expansion, were key drivers in demand growth.

Pipeline Segment Strategic Project Updates:

Minot Expansion Project: Construction began in May 2025 and will add approximately seven million cubic feet of natural gas transportation capacity per day. The project is expected to be in-service in the fourth quarter of this year.
Bakken East Project: The company is continuing negotiations with interested parties on construction of an approximately 350 mile pipeline from western North Dakota to eastern North Dakota. The focus is on project timing and volumes to determine the feasibility of the project. The company is actively working with landowners to conduct environmental and civil surveys along the potential route.
Baker Storage and Transportation Expansion: A binding open season for this proposed project concluded in May 2025. The company is reviewing results and based on initial feedback is evaluating a smaller project to align with the customer interest received in the open season.
The company continues to pursue several additional growth projects that are in various stages of development.

Guidance

MDU Resources is narrowing guidance, reflecting midyear performance and impacts from weather, and now expects earnings per share of $0.88 to $0.95, based on the following assumptions:

Normal weather, economic and operating conditions
Continued growth in utility customers at 1%–2% annually
No equity issuances in 2025
Successful execution of approved capital investment and rate recovery plans

The electric business reported net income of $10.4 million in the second quarter of 2025, compared to $15.5 million for the same period in 2024. This decrease was largely the result of higher operation and maintenance expense, primarily due to increased payroll-related costs of $1.9 million, net of tax, and higher contract services related to electric generation station planned outage-related costs of $1.6 million, net of tax. Higher software expense of $1.4 million, net of tax, which includes certain costs associated with services provided under the Transition Services Agreement with Everus that are recovered in other income, further drove the increase in operation and maintenance expense. The decrease in net income was partially offset by rate relief in South Dakota and increased commercial retail sales volumes, driven by a data center near Ellendale, North Dakota.

The natural gas distribution business reported a seasonal loss of $7.4 million in the second quarter of 2025, compared to a loss of $5.0 million for the same period in 2024. The increased seasonal loss was largely the result of higher operation and maintenance expense, primarily due to higher payroll-related costs of $2.1 million, net of tax, and increased software expenses of $900,000, net of tax, which includes certain costs associated with services provided under the Transition Services Agreement with Everus that are recovered in other income. Lower volumes due to warmer weather further drove the loss. The seasonal loss was partially offset by higher retail sales revenue due to rate relief in Washington and Montana, and higher transportation revenue.

The pipeline business reported net income of $15.4 million in the second quarter of 2025, compared to $17.3 million for the same period in 2024. The earnings decrease was driven by higher operations and maintenance expense, primarily attributable to payroll-related costs of $653,000, net of tax. The absence of $1.5 million, net of tax proceeds received in 2024 from a customer settlement further drove the decrease. The business also incurred higher depreciation expense due to growth projects placed in service throughout 2024, and higher property tax accruals in certain jurisdictions. The decrease was offset in part by higher transportation revenue due to growth projects placed in service, as previously discussed, and customer demand for short-term natural gas transportation contracts.

On Oct. 31, 2024, the company completed the separation of Everus, its former construction services business, into a new independent publicly-traded company. As a result of the separation, the historical results of operations for Everus are shown in discontinued operations, net of tax, except for allocated general corporate overhead costs of the company which did not meet the criteria for discontinued operations. Also included in discontinued operations are strategic initiative costs associated with the separation of Everus.

For the second quarter of 2025 Other reported a net loss of $4.7 million compared to net income of $32.6 million for the same period in 2024. The earnings decrease was primarily due to the absence of income from discontinued operations in 2025 and income tax adjustments related to the company's annualized estimated tax rate. Partially offsetting the decrease was lower operation and maintenance expense, primarily a result of corporate overhead costs classified as continuing operations allocated to Everus in 2024, which are not included in Other in 2025.

Also included in Other is insurance activity at the company's captive insurer, and general and administrative costs and interest expense previously allocated to the exploration and production and refining businesses that did not meet the criteria for discontinued operations.
