ALLETE, Inc. (NYSE:ALE) today reported first quarter 2025 earnings of 97 cents per share on net income of $56.1 million. Last year's first quarter results were 88 cents per share on net income of $50.7 million. Net income in 2025 includes transaction expenses of $2.1 million after-tax, or 4 cents per share, related to the announced merger. Net income in the first quarter of 2024 included transaction expenses of $1.2 million after-tax, or 2 cents per share.

"Our entire ALLETE team has been working diligently on many fronts to execute our Sustainability-in-Action strategy. Minnesota Power recently filed its latest Integrated Resource Plan, which outlines a path to achieve a portfolio that includes 90 percent renewable energy by 2035 by adding wind, solar, natural gas generation, and innovative energy storage as we work to cease coal on our system by 2035," said ALLETE Chair, President, and Chief Executive Officer Bethany Owen. "Minnesota Power's EnergyForward strategy reflects our steadfast commitment to advancing a sustainable carbon-free future while ensuring we continue to provide the reliable and affordable energy our customers expect.

"ALLETE's planned partnership with experienced infrastructure investors, Canada Pension Plan Investment Board and Global Infrastructure Partners, remains on track. Key approvals from the Federal Energy Regulatory Commission, Public Service Commission of Wisconsin and overwhelming support from our shareholders have been received. We continue working through the regulatory process toward securing our final approval from the Minnesota Public Utilities Commission, which is expected in 2025. ALLETE, Minnesota Power and all our companies, employees, customers, communities and other stakeholders will benefit from this partnership for generations to come."

ALLETE's Regulated Operations segment, which includes Minnesota Power, Superior Water, Light and Power and the Company's investment in the American Transmission Company, recorded first quarter 2025 net income of $38.4 million, compared to $44.2 million in the first quarter a year ago. Net income at Minnesota Power was lower than 2024 reflecting lower margins from industrial customers, higher operating and maintenance expense and higher depreciation expense. These decreases were partially offset by higher margins from residential, commercial and municipal customers. Net income at Superior Water, Light and Power was higher than 2024 reflecting new rates implemented in 2025 as well as higher kWh and gas sales. After-tax equity earnings in the American Transmission Company were higher than 2024 primarily due to additional equity investments.

ALLETE Clean Energy recorded first quarter 2025 net income of $7.4 million compared to $3.8 million in 2024. Net income in 2025 reflects higher production at ALLETE Clean Energy's tax equity financed wind energy facilities. Earnings in 2024 reflected negative impacts from a forced network outage near its Caddo wind energy facility.

New Energy Equity recorded 2025 first quarter net income of $9.2 million, compared to net income of $4.0 million for the same period in 2024. Net income in 2025 includes higher sales of renewable energy projects and investment tax credits at New Energy Equity compared to 2024.

Corporate and Other businesses, which include BNI Energy, ALLETE Properties and our investments in renewable energy facilities, recorded net income of $1.1 million in the first quarter of 2025, compared to a net loss of $1.3 million in 2024. Net income in 2025 includes lower income tax expense, partially offset by higher transaction expenses related to the merger in 2025. Transaction expenses were $2.1 million after-tax in 2025 compared to $1.2 million in 2024.

"Results for the first quarter of 2025 were impacted primarily by lower industrial margins as a result of lower sales to taconite customers at Minnesota Power," said ALLETE Vice President – Chief Financial Officer and Corporate Treasurer Jeff Scissons. "Our Non-regulated subsidiaries all had solid first quarter performances and are executing on their annual plans while navigating dynamic operating environments."

ALLETE is an energy company headquartered in Duluth, Minn. In addition to its electric utilities, Minnesota Power and Superior Water, Light and Power of Wisconsin, ALLETE owns ALLETE Clean Energy, based in Duluth, BNI Energy in Bismarck, N.D., New Energy Equity in Annapolis, MD, and has an eight percent equity interest in the American Transmission Co.
