The following update was provided to employees of ALLETE, Inc. and its subsidiaries on July 22, 2024:

Continued Progress Toward Completing our Transaction with CPP Investments and GIP

Over the last few weeks, we have made important progress toward securing the approvals necessary to complete our pending transaction with Canada Pension Plan Investment Board (CPP Investments) and Global Infrastructure Partners (GIP). We continue to anticipate closing the acquisition in mid-2025.

As of July 19, 2024, we have submitted filings with some of the regulatory bodies who must provide approval or clearance before we can close the transaction, including the Minnesota Public Utilities Commission (MPUC), the Public Service Commission of Wisconsin (PSCW) and the Federal Energy Regulatory Commission (FERC), among others.

Additionally, we recently filed our definitive proxy statement with the SEC. As described in the proxy statement, the special meeting for our shareholders to vote on the proposed transaction will be held on August 21, 2024, at 10:30 AM CT. Below is some important information on the shareholder vote and process for employees:

•If you are a shareholder, you should be receiving copies of the proxy materials between July 19 and July 25, 2024, by email or other method, depending on how you hold your shares. For those receiving their proxy materials electronically, proxy materials will come from the email address ALLETE, INC. <id@proxyvote.com>, with the subject heading: “ALLETE, INC Special Meeting”. The link contained in the email communication will be unique to the ALLETE stock held by each employee shareholder and will allow such shareholder to vote on the proposal with just a few clicks in a web browser. In addition, shareholders may obtain free copies of the proxy statement as described below under “Additional Information and Where to Find It.”

•Employee shareholders are encouraged to submit their proxies online or by telephone by following the procedures described in the proxy statement. The Board recommends a vote “FOR” all proposals to be presented at the special meeting. As more fully described in the proxy statement, the failure to submit a vote will have the same effect as a vote “AGAINST” the proposal to approve the Merger Agreement and the transactions contemplated thereby.

We continue to operate as usual and thank you all for your unwavering focus and hard work. Please stay tuned to the Stream where we will continue to post important updates for employees, and our transaction website at www.ALLETEforward.com. If you have any additional questions, please do not hesitate to reach out to your leader.

Per Company policy, please refer all media inquiries to Amy Rutledge at arutledge@allete.com and all analyst and shareholder inquiries to Vince Meyer at vmeyer@allete.com.

This information may involve risks and uncertainties that could cause actual results to differ materially from such forward-looking statements. These risks and uncertainties include, but are not limited to: failure to obtain the required vote of ALLETE’s shareholders; the timing to consummate the proposed transaction; the risk that the conditions to closing of the proposed transaction may not be satisfied; the risk that a regulatory approval that may be required for the proposed transaction is not obtained or is obtained subject to conditions that are not anticipated; and the diversion of management’s time on transaction-related issues.

These risks and uncertainties, as well as other risks and uncertainties that could cause ALLETE’s actual results to differ materially from those expressed in the forward looking statements, are described in greater detail in the Proxy Statement, under the heading “Item 1A. Risk Factors” in ALLETE’s Form 10-K for the year ended December 31, 2023 and in subsequently filed Forms 10-Q and 8-K, and in any other SEC filings made by ALLETE.
