ALLETE reports first quarter results and reaffirms 2014 earnings guidance

DULUTH, Minn. - ALLETE, Inc. (NYSE:ALE) today reported its financial results for the first quarter of 2014. The company reported earnings per share of 80 cents compared with 83 cents in the same period a year ago. Included in this year's results was $1.4 million after-tax, or three cents per share, of acquisition costs related to an ALLETE Clean Energy acquisition.

Compared with the first quarter of 2013, net income rose by $1 million to $33.5 million. Operating revenue for the first quarter of 2014 was $296.5 million, up twelve percent from $263.8 million in 2013. Earnings per share for the first quarter of 2014 were diluted by six cents due to an increase in the amount of common shares outstanding.

Net income at ALLETE's Regulated Operations segment, which includes Minnesota Power, Superior, Water, Light and Power and the company's investment in the American Transmission Company, was $33.9 million, an increase of $1.8 million or six percent over the first quarter of 2013. Unseasonably cold weather impacted electricity sales for the first quarter of 2014, which were three percent higher than the same period in 2013. Operating and maintenance, depreciation and interest expenses were also higher in 2014 compared with a year ago.

ALLETE's Investments and Other segment, which includes BNI Coal, ALLETE Properties, ALLETE Clean Energy, and miscellaneous corporate income and expense, recorded a net loss of $0.4 million during the period compared to net income of $0.4 million a year ago. The net loss included the $1.4 million after-tax costs for ALLETE Clean Energy's acquisition of wind energy facilities in January 2014. Quarterly results for BNI Coal and ALLETE Properties were similar to a year ago and ALLETE Clean Energy's wind facilities were accretive to earnings.

"Strong operating performances at our businesses contributed to ALLETE's first quarter earnings results," said ALLETE Chairman, President and CEO Al Hodnik. "We are comfortably on track to meet our full year earnings guidance of between $2.75 and $2.95 per share, excluding costs associated with the ALLETE Clean Energy acquisition."
