Higher electric sales boost ALLETE, Inc. first quarter results

ALLETE, Inc. (NYSE: ALE) today reported first quarter 2011 earnings of $1.07 per share on net income of $37.2 million and operating revenue of $242.2 million. This compares to earnings of 68 cents per share, net income of $23 million and operating revenue of $233.6 million recorded in the first quarter of 2010.

Year-over-year comparisons were affected by two non-recurring items. This year's quarterly results included the reversal of a $6.2 million, or 18 cents per share, deferred tax liability from a settlement agreement approved as part of Minnesota Power's 2010 rate case. 2010 results included a $4.0 million, or 12 cents per share, charge due to the Patient Protection and Affordable Care Act.

"The amount of electricity sold by our regulated utilities improved about five percent, a solid indicator of continued economic improvement in the Upper Midwest," said ALLETE President and Chief Executive,
Alan R. Hodnik. "Demand for power is ahead of what we anticipated, and we're encouraged by the prospect for new industrial customer growth in our region."

Regulated Operations at ALLETE recorded $38.4 million of income in 2011's first quarter, highlighted by a five percent increase in electricity sold. Minnesota Power income increased year-over-year in the first quarter, as did income at Superior Water, Light & Power Co. in Wisconsin. Income from ALLETE's investment in the American Transmission Co. remained steady.

The Investments and Other segment trimmed its loss in the first quarter of 2011, compared to the same period a year ago, by $700,000. Financial results from ALLETE Properties showed year-over-year improvement, and North Dakota's BNI Coal recorded similar earnings in the first quarters of both 2010 and 2011.

Hodnik said that because of expectations for increased electric sales, the company now projects 2011 earnings to be between $2.40 and $2.60 per share.
