BISMARCK, N.D. (AP) — MDU Resources Group Inc. has reported an increase in profits for 2013, helped by record earnings in its construction services business and an increase in natural gas sales.
The Bismarck-based energy, mining and construction company says its profits for 2013 rose to $278.2 million, or $1.47 per share. That's up from a loss of $1.4 million, 1 cent per share in 2012.
MDU says its construction services business had record earnings of $52.2 million last year.
The utility business reported earnings of $72.5 million. That's a 21 percent increase over 2012.
MDU is the parent company of Montana-Dakota Utilities. The company says colder-than-normal temperatures at the beginning and end of 2013 helped increase natural gas sales by 15 percent.
