**MDU Resources Group Announces Increased Capital Investment Plan for 2026-2030**

BISMARCK, N.D. — November 20, 2025 — MDU Resources Group, Inc. (NYSE: MDU) today announced a capital investment plan totaling $3.4 billion from 2026 through 2030, an increase over the company's prior 2025–2029 planned capital investment of $3.1 billion. This increase reflects the company's continued investment in safe, reliable and environmentally-responsible energy delivery infrastructure across its regulated electric, natural gas distribution and pipeline businesses.

This five-year plan represents an approximately 34% increase over the previous five-year period, 2021-2025, and underscores the company's focus on sustainable growth as a pure-play regulated energy delivery business.

"Our capital investment plan for 2026 through 2030 reflects our commitment to building the energy infrastructure that communities depend on," said Nicole Kivisto, MDU Resources president and CEO. "We're investing to serve a growing customer base, to modernize and strengthen our systems for the future and to continue delivering long-term value for our stockholders. These planned investments demonstrate the steady, disciplined approach that defines MDU Resources. We're focused on safety, reliability and growth that benefits our customers, communities and stockholders."

**Capital Investments by Segment** 

MDU Resources' planned investments over the 2026–2030 period include increases across its regulated segments:

The company's electric utility capital investments will fund continued system upgrades, substation improvements and generation projects, including final payment in 2026 for the acquisition of a 49% stake in Badger Wind Farm. Additionally, the Jamestown to Ellendale transmission line (JETx) project continues to advance, and the company anticipates energizing the line in late 2028 to early 2029.

On the natural gas distribution side, capital investments will focus on system replacements, expansions and modernization projects to meet demand from a growing customer base. This includes investments in new service extensions and capacity expansions that accommodate economic and population growth in fast-growing regions across our eight-state territory.

------

The pipeline business will continue to support customer-driven projects. The planned Line Section 32 Expansion Project is anticipated to serve power generation while other projects, like the planned Minot Industrial Expansion Project, are aimed at serving industrial demand in the region. Additionally, capital investments focus on system maintenance and expanding capacity where market conditions support additional investment.

**Equity and Funding Plan** 

Equity issuance in the range of $150 million to $175 million is anticipated in 2026, and in the range of $100 million to $125 million in 2027, to support MDU Resources' near-term capital expenditures for growth. The company expects the remaining funding to come from internally generated cash flows and debt financing and will review equity needs beyond 2027 in later periods as longer-term investment plans are updated.

**Strategic Growth and Value Creation** 

The company believes the 2026–2030, $3.4 billion capital investment plan positions MDU Resources to continue achieving rate base growth in the 7%–8% range annually across its regulated operations, while maintaining its long-term earnings per share growth target of 6%–8%. Actual expenditures may differ from estimates because of changes in load growth, regulatory decisions, permitting or other factors.
