MDU Resources is Building a Strong America®
A strong infrastructure is the heart of the American economy. It is the natural gas and electricity that power business, industry and our daily lives. It is the pipes and wires that connect our homes, factories, offices and stores to bring them to life. It is the transportation network of roads, highways and airports that keeps our economy moving. Infrastructure is our business.
We provide essential products and services through our regulated energy delivery and construction materials and services businesses.
Our company was founded in 1924 as a small electric utility serving a handful of farm communities on the border of Montana and North Dakota. We realized early the value of delivering a variety of services, and we grew our company by developing a core line of businesses.
Today, we are a multibillion-dollar corporation headquartered in Bismarck, North Dakota, with operations and customers across the country. MDU Resources is the largest publicly traded company headquartered in North Dakota, and we do business in 48 states.
Since 1948, our stock has been traded on the New York Stock Exchange. It trades under the symbol MDU.
