SECTION 2 - FINANCIAL INFORMATION

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On July 9, 2025, ALLETE, Inc. (ALLETE or Company) issued $250 million of the Company's first mortgage bonds (the "Bonds") to certain institutional buyers in the private placement market. The Bonds were sold in reliance on an exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended, to institutional accredited investors.

The Bonds were issued in four series as follows:


Maturity Date	Principal Amount	Interest Rate
July 9, 2032	$50 million	5.37%
July 9, 2035	$75 million	5.69%
July 9, 2037	$50 million	5.79%
July 9, 2055	$75 million	6.34%

Interest on the Bonds is payable semi-annually on January 15 and July 15 of each year, commencing on January 15, 2026. The Company has the option to prepay all or a portion of the Bonds at its discretion, subject to a make-whole provision; however, each series of bonds is redeemable at par, including, in each case, accrued and unpaid interest, three months prior to the maturity date of the series maturing in 2032, 2035 and 2037, and six months prior to the maturity date of the series maturing in 2055. The Bonds will be subject to additional terms and conditions which are customary for these types of transactions. ALLETE plans to use the proceeds from the sale of the Bonds to fund utility capital expenditures.

New factors emerge from time to time, and it is not possible for management to predict all of these factors, nor can it assess the impact of each of these factors on the businesses of ALLETE or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statement. Readers are urged to carefully review and consider the various disclosures made by ALLETE in this Form 8-K and in other reports filed with the SEC that attempt to identify the risks and uncertainties that may affect ALLETE’s business.
