ALLETE reports first quarter 2010 earnings of 68 cents per share

ALLETE, Inc. (NYSE: ALE) today reported first quarter 2010 earnings of 68 cents per share, which compares to 55 cents per share reported in the first quarter of 2009. Last year's results were reduced by $3.2 million after-tax, or 10 cents per share, representing the 2008 portion of interim rate refunds. Excluding that charge, earnings per share would have been 65 cents for the first quarter of 2009.

ALLETE's net income was $23.0 million on total operating revenue of $233.6 million in the first quarter of 2010. In the same period a year ago, net income was $16.9 million on total operating revenue of $199.6 million.

Regulated Operations earned $24.9 million in the first quarter of 2010, compared with $17.7 million in the first quarter a year ago. The period-over-period increase includes the impact of the aforementioned $3.2 million charge, Minnesota Public Utilities Commission-approved interim rates, new FERC-approved rates, and increased transmission related margins. These increases were significantly offset by higher operating, depreciation, and income tax expenses. Income tax expense included a $3.6 million charge resulting from the Patient Protection and Affordable Care Act of 2010. Earnings from ALLETE's investment in the American Transmission Company rose by $0.3 million from the same period a year ago.

"We've continued to make significant capital expenditures, including those for mandated environmental improvements and renewable energy additions," said ALLETE President Alan R. Hodnik. "However, because interim rates are substantially below our requested levels, this year we do not anticipate Minnesota Power will earn the return on equity that has been authorized by the MPUC."

ALLETE Chairman Don Shippar, who is retiring as CEO effective April 30, said the company was encouraged by indications that the economic outlook is brightening.

"It's good news for northern Minnesota and the whole region to have its major industry - taconite mining - enjoy increasing production levels," Shippar said. "Prospects for this industry are clearly better than they were a year ago."

The Investments and Other segment recorded a net loss of $1.9 million during the quarter, compared with a net loss of $0.8 million in 2009. Results in 2010 included a slightly larger net loss at ALLETE Properties than the year before, and a $0.4 million charge related to the Patient Protection and Affordable Care Act.

The average number of shares outstanding of ALLETE common stock increased year-over-year as the company continued to fund its capital investments, resulting in dilution of six cents per share.

Hodnik added that ALLETE's earnings guidance for 2010 remains unchanged at $2.05 to $2.35 per share, and provides for a range of potential regulatory outcomes. The earnings guidance excludes the impact of the non-recurring 12 cents per share charge resulting from the Patient Protection and Affordable Care Act.
