**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.

**Forward-Looking Statements**

Statements in this report that are not statements of historical facts are considered "forward-looking" and, accordingly, involve risks and uncertainties that could cause actual results to differ materially from those discussed. Although such forward-looking statements have been made in good faith and are based on reasonable assumptions, there can be no assurance that the expected results will be achieved. Any statements that express, or involve discussions as to, future expectations, risks, beliefs, plans, objectives, assumptions, events, uncertainties, financial performance, or growth strategies (often, but not always, through the use of words or phrases such as "anticipates," "believes," "estimates," "expects," "intends," "plans," "projects," "likely," "will continue," "could," "may," "potential," "target," "outlook" or words of similar meaning) are not statements of historical facts and may be forward-looking.

In connection with the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, we are providing this cautionary statement to identify important factors that could cause our actual results to differ materially from those indicated in forward-looking statements made by or on behalf of ALLETE in this Current Report on Form 8-K (Form 8-K), in presentations, on our website, in response to questions or otherwise. These statements are qualified in their entirety by reference to, and are accompanied by, the following important factors, in addition to any assumptions and other factors referred to specifically in connection with such forward-looking statements that could cause our actual results to differ materially from those indicated in the forward-looking statements:

• effects of competition, including competition for retail and wholesale customers;

• effects of restructuring initiatives in the electric industry;

• the impacts on our businesses of climate change and future regulation to restrict the emissions of greenhouse gases;

• effects of increased deployment of distributed low-carbon electricity generation resources;

• the impacts of laws and regulations related to renewable and distributed generation;

• pricing, availability and transportation of fuel and other commodities and the ability to recover the costs of such commodities;

• our current and potential industrial and municipal customers' ability to execute announced expansion plans;

• real estate market conditions where our legacy Florida real estate investment is located may deteriorate;

required governmental and regulatory approvals or agreements with other parties interested therein may delay the Merger, may subject the Merger to or impose adverse conditions or costs, or may cause the parties to abandon the Merger;

• the timing and costs incurred to consummate the Merger;

• the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement or could otherwise cause the failure of the Merger to be consummated on the timeline anticipated; and

• the announcement and pendency of the Merger, during which ALLETE is subject to certain operating restrictions, could have an adverse effect on ALLETE's businesses, results of operations, financial condition or cash flows.

Additional disclosures regarding factors that could cause our results or performance to differ from those anticipated by this report are discussed in Part I, Item 1A. Risk Factors of ALLETE's Annual Report on Form 10-K for the year ended December 31, 2024. Any forward-looking statement speaks only as of the date on which such statement is made, and we undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which that statement is made or to reflect the occurrence of unanticipated events. 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.
