Company overview

MDU RESOURCES GROUP INC

MDU Resources Group Inc. is a diversified energy and infrastructure holding company that unites regulated utility, construction materials, and logistics services under the familiar ticker MDU, and CIK 67716 anchors its disclosures for investors tracking this multi-line operator. Serving municipal, commercial, and industrial clients across its heavy civil construction, building products, pipeline construction, and electric and natural gas utility businesses, the company delivers essential services born from its roots in SIC 4221 (local trucking) and 4911 (electric services), with an expanding reach into midstream and telecom infrastructure solutions. Core offerings span regulated utility delivery, contractor services, and aggregates, targeting cities, contractors, and energy-intensive industries that demand reliability and safety. Material risks include regulatory scrutiny from state utility commissions, weather-driven operational disruptions, commodity-cost volatility, and the capital intensity of long-duration infrastructure projects, while compliance pressures from federal and state environmental statutes remain ever-present.
