ALLETE, Inc. quarterly earnings increase from a year ago

Full-year earnings guidance adjusted upward to $3.20-$3.40 per share

DULUTH, Minn. – ALLETE, Inc. (NYSE: ALE) today reported second quarter 2015 earnings of 46 cents per share on net income of $22.5 million and operating revenue of $323.3 million. Earnings for the second quarter of 2014 were 40 cents per share on net income of $16.8 million and operating revenue of $260.7 million. This year’s results included acquisition transaction fees amounting to $0.9 million, or two cents per share. In last year’s quarterly results was a $2.5 million, or six cents per share, non-recurring charge associated with a settlement agreement with the Environmental Protection Agency (EPA).

ALLETE’s Regulated Operations segment, which includes Minnesota Power, Superior Water, Light and Power and the company’s investment in the American Transmission Co., recorded net income of $23.6 million, an increase of $6.1 million over 2014 second quarter net income. This year’s results reflect increases in cost recovery rider revenue, production tax credits, and power marketing sales due to the commencement of the Minnkota Power sales agreement in June 2014, partially offset by increased depreciation and interest expense. Included in last year’s quarterly results was the previously mentioned non-recurring charge related to a settlement agreement with the EPA.

“With respect to Minnesota Power and the region it serves, we are pleased that our large power taconite customers nominated near 90% of full electricity demand levels for the fourth quarter of 2015.” said ALLETE Chairman, President and CEO Al Hodnik.

The Investments and Other segment, which includes U.S. Water Services, ALLETE Clean Energy, BNI Coal, ALLETE Properties, corporate expense and unallocated interest expense, posted a net loss of $1.1 million, compared to a second quarter 2014 net loss of $700,000 a year ago. Operating results from the companies in this segment were as expected. The net loss for the second quarter of 2015 included acquisition transaction fees of $.9 million and higher interest and income tax expenses. The increase in income tax expense included $1.2 million attributable to the first quarter of 2015, due to a higher estimated effective tax rate for the year.

An increase in common shares outstanding resulted in 7 cents of earnings per share dilution compared to the same period a year ago.

“Overall, these solid financial results are as we anticipated in the quarter and when we examine them closely we find evidence that the strategy to broaden our energy operations is taking hold,” said Hodnik. “The recent addition of U.S. Water Services and the consistent growth of ALLETE Clean Energy, combined with our strong utility base, set the stage for future growth.”

ALLETE’s 2015 full-year guidance has been adjusted upward to a range of $3.20 to $3.40 per share to include ALLETE Clean Energy’s expected development fee from the MDU transaction. On June 30, 2015, the North Dakota Public Service Commission approved the sale of a wind facility under construction by ALLETE Clean Energy, to MDU. The company estimates the development fee from the MDU transaction to be between $20 million and $25 million, pre-tax, of which most will be recognized in earnings during the second half of 2015.

The 2015 guidance excludes acquisition-related transaction fees. Additional details about earnings guidance for the year will be discussed in our conference call scheduled for today.
