ALLETE, Inc. reports third quarter earnings of $1.49 per share;

raises full-year 2023 earnings guidance to a range of $4.30 to $4.40 per share reflecting increased earnings from ALLETE Clean Energy

DULUTH, Minn. - ALLETE, Inc. (NYSE: ALE) today reported third quarter 2023 earnings of $1.49 per share on net income of $85.9 million. Last year’s third quarter results were 59 cents per share on net income of $33.7 million.

“We are pleased with our solid financial results this quarter and the positive momentum going into the end of the year,” said ALLETE Chair, President, and Chief Executive Officer Bethany Owen. “We continue to deliver on our Sustainability in Action strategy, including our most recent announcement that Minnesota Power has been awarded a $50 million grant by the U.S. Department of Energy to modernize its high-voltage direct current transmission system. As planned, Minnesota Power also filed a rate case yesterday in support of its EnergyForward strategy, to align investments and our work force with the state of Minnesota legislation requiring 100% carbon-free energy by 2040. In addition, New Energy Equity has a robust pipeline of renewable energy projects, which is expected to result in strong financial results in the fourth quarter and beyond. Together, these key steps forward demonstrate the significant progress we are making in advancing a sustainable clean-energy future.”

“Our results for the third quarter of 2023 reflect a favorable arbitration award for a subsidiary of ALLETE Clean Energy,” said ALLETE Senior Vice President and Chief Financial Officer Steve Morris. “Our regulated operations results were lower in the quarter, reflecting timing of interim rate reserves in 2023 compared to 2022. We continue to expect New Energy Equity to achieve or slightly exceed our original full-year earnings projections. Considering a number of factors occurring during the year, as well as our expectations for the fourth quarter, we have raised ALLETE’s 2023 full-year earnings guidance to a range of $4.30 to $4.40 per share.”

“Specific items affecting ALLETE’s updated guidance include the third quarter arbitration award, a third-party network outage expected to negatively impact the Caddo wind facility in the fourth quarter, and historically low wind across much of the nation affecting earnings at ALLETE Clean Energy wind facilities throughout the year. These items in total had a net positive impact on our updated guidance of approximately 30 cents per share,” said Morris.

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 third quarter 2023 net income of $34.0 million, compared to $38.3 million in the third quarter a year ago. Earnings at Minnesota Power were lower this year compared to 2022, primarily due to interim rate refund reserves recognized in 2023, resulting from Minnesota Power’s 2022 general rate case outcome; the full interim rate reserve was recorded in the fourth quarter of 2022. These decreases were partially offset by increased sales to industrial customers.

ALLETE Clean Energy recorded third quarter 2023 net income of $54.8 million, which reflects the gain recognized for the favorable arbitration award, compared to a net loss of $7.3 million in 2022. Net income in 2022 included a $2.9 million after-tax reserve for an anticipated loss on the sale of ALLETE Clean Energy’s Northern Wind project.

Corporate and Other businesses, which include New Energy Equity, BNI Energy, ALLETE Properties and investments in renewable energy facilities, recorded a net loss of $2.9 million in the third quarter of 2023, compared to net income of $2.7 million in 2022. Third quarter net income in 2023 reflects increased income tax expense, partially offset by earnings from Minnesota solar projects. New Energy’s earnings in this quarter were slightly below 2022, primarily due to the timing of project closings, now expected in the fourth quarter, and higher operating and maintenance expense as compared to last year.
