About MDU Resources Group, Inc.
MDU Resources Group Inc is a pure-play regulated energy delivery business. It is organized into three reportable business segments: Electric, Natural Gas Distribution, and Pipeline. Maximum revenue is generated from the Pipeline segment, which provides natural gas transportation and underground storage services through a FERC-regulated pipeline system mainly in the Rocky Mountain and northern Great Plains regions of the United States. This segment also provides non-regulated energy-related services, including cathodic protection. The electric segment generates, transmits, and distributes electricity in Montana, North Dakota, South Dakota, and Wyoming, and the natural gas distribution segment distributes natural gas in those states, as well as in Idaho, Minnesota, Oregon, and Washington.
