Welcome to our dedicated page for Mdu Resources SEC filings (Ticker: MDU), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
MDU Resources Group, Inc. filings document the operations, capital structure and governance of a NYSE-listed regulated energy delivery company. Form 8-K reports furnish quarterly and annual results, investor presentations, capital-investment plan updates and material agreements involving revolving credit, private shelf notes and forward-sale equity transactions.
Proxy materials describe board elections, executive compensation, equity awards and shareholder-voting matters. The filings also identify the company’s common stock, par value $1.00 per share, and provide formal disclosure around financing covenants, subsidiary-level pipeline funding arrangements and other capital-structure matters tied to utility and natural gas pipeline operations.
MDU Resources Group is asking stockholders to vote at its virtual 2026 annual meeting on four items: electing eight directors, an advisory approval of named executive officer pay, approving an Amended and Restated Long-Term Incentive Plan (LTIP), and ratifying Deloitte as independent auditor for Fiscal 2026.
The company highlights its first full year as a pure-play regulated energy business, serving more than 1.2 million electric and natural gas customers across eight states with 863 MW of owned generation and 30,840 miles of lines. In 2025 it recorded consolidated net income of $190.4 million, including record pipeline earnings of $68.2 million, and increased operating revenues by 6.7% while declaring $110.3 million in dividends, its 88th consecutive year of uninterrupted payouts.
MDU emphasizes its CORE strategy—Customers and communities, Operational excellence, Returns focused, and Employee driven—alongside board refreshment, majority voting, proxy access, independent board leadership, robust risk and AI governance, and a pay-for-performance program where 80% of the CEO’s 2025 target compensation and 63% of other NEOs’ target compensation were at risk, driven by financial, customer satisfaction, reliability, and safety goals.
MDU Resources Group Inc Schedule 13G/A Amendment No. 14 filed by The Vanguard Group reports beneficial ownership of 0 shares, representing 0% of the class. The filing explains an internal realignment effective January 12, 2026, after which certain Vanguard subsidiaries will report disaggregated holdings and Vanguard no longer is deemed to beneficially own those securities. The amendment is signed by Ashley Grim, Head of Global Fund Administration, dated 03/27/2026.
MDU Resources Group, Inc. files its Form 10-K describing its transformation into a pure-play regulated energy delivery company. It now focuses on three segments: electric, natural gas distribution and pipeline, all operating under state commissions and FERC oversight.
The company completed the separations of Knife River in 2023 and Everus in 2024, leaving a fully regulated profile. It serves about 146,550 electric customers and over 1.08 million natural gas customers, and owns a FERC-regulated pipeline with extensive storage capacity.
Key themes include heavy regulation of rates and returns, use of riders and trackers to reduce regulatory lag, growing exposure to data-center and RNG demand, and detailed disclosure of environmental, wildfire, weather, cybersecurity, capital market and aging-infrastructure risks that could affect future costs and earnings.
