MDU Resources Group, Inc. (MDU) Stock Price & How to Invest

MDU Resources Group runs three regulated businesses out of Bismarck, North Dakota. Montana-Dakota Utilities provides electric service across the Northern Plains; Montana-Dakota, Cascade Natural Gas and Intermountain Gas distribute natural gas across the Pacific Northwest and Midwest; and WBI Energy operates a natural gas transmission and storage network of more than 3,800 miles. Together those serve roughly 1.2 million customers. The company that carried this ticker a few years ago looked nothing like this: MDU separated Knife River Corporation (construction materials and aggregates) in May 2023 and Everus Construction Group (specialty contracting) in October 2024, which is why trailing revenue of roughly $1.8 billion sits well below the multi-billion figures in older reference data. MDU is now a member of the S&P SmallCap 600 rather than an industrial conglomerate.

The investment picture has two layers. Underneath is an ordinary regulated utility: earnings come from the allowed return on an approved rate base, growth comes from spending capital and getting commissions to let you recover it, and management has laid out roughly $3.1 billion of capital expenditure across 2026 through 2030 against a long-term earnings-per-share growth objective of 6% to 8%. On top of that sits the proposed Bakken East Pipeline, a $2.7 billion to $3.2 billion project that is explicitly incremental to the capital plan and is roughly two thirds of the company's entire market value. MDU has executed precedent agreements covering nearly 1.2 billion cubic feet per day of firm transportation, but no final investment decision has been made and the FERC Section 7(c) application is not expected until the fourth quarter of 2026. Layered onto both is data center demand in North Dakota, including an electric service agreement with Applied Digital for a campus that would draw up to 430 megawatts at full capacity, still pending state approval.

Financing costs are already visible in the numbers: second-quarter interest expense rose to $31.5 million from $25.4 million a year earlier, and long-term debt grew to roughly $2.6 billion from about $2.0 billion, while share count moved from about 204 million to 210 million, so both debt and equity issuance are diluting the benefit of new investment. Regulatory lag is the structural risk, because interim rates in Montana and elsewhere are collected subject to refund and requested increases are routinely settled below the ask. Weather swings the gas business hard, as first-quarter 2026 revenue fell about 12% year over year and the second quarter is seasonally a loss for gas distribution. Bakken East carries the tail risk in either direction, since a project costing up to $3.2 billion against a market capitalization near $4.3 billion could reshape the balance sheet if sanctioned, or leave development spending stranded if it is not. Smaller matters include manufactured gas plant environmental cleanup claims and the routine litigation disclosed in the commitments note, none of which the company describes as material, and the general illiquidity that comes with a small-cap listing.

A price target is what an analyst published on a date, not a prediction, and sell-side ratings skew positive across the whole market.

We give no verdict on MDU Resources Group, Inc.. Both cases are real, which is why the question is contested at all, so here is the strongest version of each.

The case for buying. Rate base growth and a dense rate-case calendar. MDU plans roughly $3.1 billion of capital expenditure from 2026 through 2030, split about $1.4 billion to natural gas distribution, $1.1 billion to electric and $643 million to pipeline. The most optimistic published target, $27.00, assumes this works close to its best case.

The case against. Financing costs are already visible in the numbers: second-quarter interest expense rose to $31.5 million from $25.4 million a year earlier, and long-term debt grew to roughly $2.6 billion from about $2.0 billion, while share count moved from about 204 million to 210 million, so both debt and equity issuance are diluting the benefit of new investment. The most pessimistic target, $21.00, is roughly what MDU is worth if this bites instead.

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see MDU Resources Group, Inc.'s investor relations page or your broker.

• Revenue (TTM): ~$1.81B
• Net income (TTM): ~$197M
• Diluted EPS (TTM): ~$0.95, with 2026 guidance reaffirmed at $0.93 to $1.00
• Market cap: ~$4.3B (~$20.55 per share on ~210M shares)
• P/E (TTM): ~22x
• Dividend: ~$0.145 per quarter (~$0.58 annualized), yield ~2.8%

Second-quarter 2026 net income came in at $21.3 million, up 55.5% from $13.7 million a year earlier, on operating revenue of $375.2 million. Trailing revenue of roughly $1.81 billion reflects the post-spin perimeter only, so comparisons against pre-2023 figures that included Knife River and Everus are not meaningful. At about 22 times trailing earnings with a 6% to 8% long-term growth objective and a payout near 60% of earnings, MDU trades in the range of regulated utility peers rather than at a discount, and book value per share of roughly $13.90 puts the stock near 1.5 times book.

Other names that sit close to MDU: same theme, named as a direct competitor, or held beside it in the same funds. Each entry says which. Worth a look if you are thinking about diversification within a thesis rather than concentration on one ticker.

There are three common ways to get MDU exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it, which spreads the position across many companies. Or build it into a focused thematic portfolio, so MDU sits alongside other stocks that express the same thesis.

Walnut takes the portfolio route. Describe a thesis where MDU fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.

MDU is a small-cap regulated utility whose steady rate-base earnings are the base case and whose Bakken East pipeline ambition is the swing factor, for better or worse.

Whether MDU is worth buying today depends more on your time horizon and what you already hold than on any single call. We walk through valuation, what would have to go right, and the risks in is MDU a buy or a sell?, and where the stock could go from here in the MDU stock forecast.
