The following update was provided to employees of ALLETE, Inc. and its subsidiaries on August 14, 2024.
Reminder to vote on proposed transaction

ALLETE recently filed its definitive proxy statement with the SEC. As described in the proxy statement, the special meeting for shareholders to vote on the proposed transaction will be held on Aug. 21, 2024, at 10:30 a.m. Central Daylight Time. Below is some important information on the shareholder vote and process for employees:
If you are a shareholder, you should have received 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 should have 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 the 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.
