ALLETE, Inc. Reports Second Quarter 2025 Earnings

ALLETE, Inc. (NYSE:ALE) today reported second quarter 2025 earnings of 55 cents per share on net income of $31.9 million. Last year's second quarter results were 57 cents per share on net income of $33.0 million. Net income in the second quarter of 2025 includes transaction expenses of $3.4 million after-tax, or 6 cents per share, related to the announced merger. Net income in the second quarter of 2024 included transaction expenses of $14.5 million after-tax, or 25 cents per share.

"Our entire ALLETE team continues to work diligently to execute our Sustainability-in-Action strategy. On July 11, 2025, we were pleased to announce a settlement agreement reached between the Minnesota Department of Commerce, Minnesota Power and its transaction partners Canada Pension Plan Investment Board ("CPP Investments") and Global Infrastructure Partners ("GIP") that will deliver enhanced benefits for our customers, our employees and the communities we serve," said ALLETE Chair, President, and Chief Executive Officer Bethany Owen. "The settlement agreement is a strong, positive step forward in ALLETE's planned partnership with experienced infrastructure investors, CPP Investments and GIP and demonstrates our commitment to listening and working collaboratively with our stakeholders."

ALLETE continues to expect the proposed transaction to close in 2025, subject to approval by the Minnesota Public Utilities Commission and other customary closing conditions. Required approvals have been received from all other parties.

ALLETE also announced Superior Water, Light and Power's ("SWLP") leadership advanced legislation to help their customers replace lead service lines by working with state and local leaders to support a change in Wisconsin law that will allow SWLP to access federal grants to help offset costs for SWLP customers. The change has been passed by the legislature and signed into law by Governor Evers.

ALLETE's Regulated Operations segment, which includes Minnesota Power, SWLP and the Company's investment in the American Transmission Company, recorded second quarter 2025 net income of $23.0 million, compared to $33.7 million in the second quarter a year ago. Net income at Minnesota Power was lower than 2024 reflecting lower margins from industrial customers, higher operating and maintenance expense, higher depreciation expense due to the impact of estimated compliance costs related to an EPA Rule finalized in May 2024 and lower transmission margins. Net income at SWLP was higher than 2024 reflecting new rates implemented in 2025. After-tax equity earnings in the American Transmission Company were higher than 2024 primarily due to additional equity investments.

ALLETE Clean Energy recorded second quarter 2025 net income of $900 thousand compared to $2.4 million in 2024. Net income in 2025 reflects lower production and unfavorable pricing at most wind sites, partially offset by higher production at ALLETE Clean Energy's Caddo wind energy facility. Earnings in 2024 reflected negative impacts from a forced network outage near its Caddo wind energy facility.

New Energy Equity recorded 2025 second quarter net income of $4.7 million, compared to net income of $7.7 million for the same period in 2024. Net income in 2025 includes lower sales of renewable energy projects due to timing of project closings. These decreases were partially offset by higher earnings from tax equity financed solar energy facilities.

Corporate and Other businesses, which include BNI Energy, ALLETE Properties and our investments in renewable energy facilities, recorded net income of $3.3 million in the second quarter of 2025, compared to a net loss of $10.8 million in 2024. Net income in 2025 reflects lower merger-related expenses compared to 2024, and lower income tax expense. Merger-related expenses were $3.4 million after-tax in 2025 compared to $14.5 million in 2024.

"Results for the second quarter of 2025 were impacted primarily by lower industrial margins as a result of lower sales to taconite customers at Minnesota Power which are expected to continue through 2025," said ALLETE Vice President – Chief Financial Officer and Corporate Treasurer Jeff Scissons. "Absent the closing of the transaction and the rate case stay-out provision in the settlement agreement with the Minnesota Department of Commerce, Minnesota Power would be filing a rate case to account for reduced revenue, increased depreciation from capital investments and inflationary pressures. The rate case stay-out provision in the settlement agreement provides immediate customer savings on top of numerous other commitments that benefit ALLETE stakeholders, customers and communities."
