MGE Energy Reports Fourth-Quarter Earnings

Madison, Wis., Feb. 26, 2015—MGE Energy, Inc. (Nasdaq: MGEE) today reported earnings for the three months ended Dec. 31, 2014, of $15.2 million, or 44 cents per share, compared to $14.1 million, or 41 cents per share, for the same period in the prior year. MGE Energy reported earnings for the twelve months ended Dec. 31, 2014, of $80.3 million, or $2.32 per share, compared to $74.9 million, or $2.16 per share, for the same period in the prior year.

During the three months ended Dec. 31, 2014, the company benefited from Madison Gas and Electric's (MGE) ongoing effort to manage costs including lower benefit costs, which led to slightly higher earnings. In addition, in October 2014 customers received a fuel credit on their bill related to fuel savings of $6.5 million that MGE was able to achieve during 2013.

For the twelve months ended Dec. 31, 2014, earnings increased $5.4 million compared to the same period in the prior year. This increase in earnings was driven primarily by savings from MGE's ongoing effort to manage operating and maintenance costs, lower benefit costs and colder winter temperatures. Gas retail sales volume increased during the year 4.8% in part due to colder weather in the first quarter of 2014 compared to the same period in the prior year. The average temperatures in January and February 2014 were 11.5 degrees and 12.5 degrees, respectively, compared to normal average temperatures of 19.4 degrees and 23.7 degrees, respectively.
