**PROXY STATEMENT**

**________________________________________________________________**

This Proxy Statement is furnished in connection with the solicitation by the Board of proxies to be voted at our 2023 Annual Meeting to be held as a virtual-only webcast on Tuesday, May 9, 2023, at

10:30 a.m. Central Daylight Time, or at any postponement or adjournment of the Annual Meeting.

The virtual Annual Meeting Site is <u>www.virtualshareholdermeeting.com/ALE2023</u>.

On or about March 23, 2023, we first mailed or otherwise made available to our shareholders a Notice of Internet Availability of Proxy Materials containing instructions for how to access our proxy materials, which includes our Notice and Proxy Statement, and our 2022 Form 10-K. The Notice of Internet Availability of Proxy Materials also includes instructions to access your form of proxy to vote your shares online. In accordance with their particular prior requests, certain shareholders have received email notification of how to access our proxy materials and vote online, or have been mailed paper copies of our proxy materials and proxy card.

Electronic distribution of our proxy materials expedites receipt by shareholders, lowers the cost of the Annual Meeting, and conserves vital natural resources. If you would prefer to receive printed proxy materials, please follow the instructions included in the Notice of Internet Availability of Proxy Materials to request a printed copy at no charge. If you have previously elected to receive our proxy materials electronically, you will continue to receive email notification with instructions to access the materials via the Internet unless you elect otherwise.

------

**FREQUENTLY ASKED QUESTIONS**

**________________________________________________________________**

**Why did I receive these proxy materials?**

You received these materials because you were an ALLETE shareholder at the close of business on March 10, 2023 (the Record Date) and, therefore, you are entitled to vote at the Annual Meeting.

**Who pays for the cost of soliciting proxies?**

We expect to solicit proxies primarily via the Internet and by mail. Our directors, officers, other employees, and agents may contact you by telephone, email, mail, or in person. We will pay the expense of any such solicitation, as well as the costs of preparing, printing, and distributing our proxy materials. We will also reimburse brokers, banks, and other custodians, nominees, and fiduciaries for their reasonable out-of-pocket expenses for forwarding proxy and solicitation materials to beneficial owners of Common Stock.

We have also retained Georgeson LLC to assist in the solicitation of proxies. We expect to pay Georgeson LLC approximately $10,000 plus expenses in connection with soliciting proxies and providing proxy advisory services. Directors and employees do not receive additional compensation for soliciting shareholder proxies.

**Why did I receive a Notice of Internet Availability of Proxy Materials directing me to the internet instead of a full-set paper copy of the proxy materials?**

We are primarily providing our shareholders internet access to our proxy materials to facilitate prompt delivery of this important information, to reduce the environmental impacts of our Annual Meeting, and to manage costs. On March 10, 2023, we began delivery, primarily by mail, of a Notice of Internet Availability of Proxy Materials to our shareholders and we posted our proxy materials on the website referenced in the Notice of Internet Availability of Proxy Materials: <u>www.proxyvote.com</u>.

As set out on the Notice of Internet Availability of Proxy Materials and also explained on the next page, you may choose to access these proxy materials on the website or you may request to receive printed copies of our proxy materials at no charge.

------

**How can I request to receive a paper copy of these proxy materials?**

You may request a copy of the proxy materials, at no charge, using one of the following methods:

![ale-20230320_g3.jpg](ale-20230320_g3.jpg)**Telephone**: Call, toll-free in the U.S., (800) 579-1639. Follow the instructions to log in and order copies.

![ale-20230320_g4.jpg](ale-20230320_g4.jpg)**Email**: Send an email to **sendmaterial@proxyvote.com** with your 16-digit control number in the subject line. (Your control number can be found next to the label "Control Number" on your Notice of Internet Availability, proxy card, or voting instruction form.)

The email needs to include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Your preference to receive printed materials via the mail or to receive an email with links to the electronic materials;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If you choose email delivery, you must include the email address to which you want the proxy materials sent; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If you would like your election to apply to delivery of material for all future meetings, write the word "Permanent" and include the last four digits of your Social Security Number or

Tax Identification Number in the email.

**How can I subscribe to electronic delivery of proxy materials?**

With your consent, we will no longer send you paper copies of any proxy materials, including the Notice of Internet Availability of Proxy Materials, beginning next year. Instead, we will send you an email notification that the shareholder materials are available for you to view, including a link to the website where you can view the materials. We will also provide you with a link to allow you to vote your shares of Common Stock online. To sign up for electronic receipt of shareholder materials, follow these directions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.Log onto the Internet at <u>www.allete.com</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.Click on "Investors."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.Click on "Shareholder Services."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.Click on "Proxy Electronic Delivery."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.Follow the prompts to submit your electronic consent.

You will receive an email confirmation of your enrollment. You will continue to receive your shareholder materials electronically for as long as you remain a shareholder and the email account that you provide the Company remains active, unless you choose to cancel your enrollment, which you may do at any time.

**&nbsp;&nbsp;&nbsp;&nbsp;**

**Why did I receive multiple Notices of Internet Availability of Proxy Materials or proxy cards?**

This means your shares of Common Stock are registered differently or are in more than one account. Please provide voting instructions for all your shares. We encourage you to have all accounts registered in the same name and address whenever possible. You can accomplish this by contacting ALLETE Shareholder Services at (218) 355-3114 or by writing to ALLETE, Inc., Attention: Shareholder Services, 30 West Superior Street, Duluth, MN 55802.

------

**I received more than one complete set of proxy materials. Is it possible to eliminate duplicates?**

If you hold stock in more than one account or if you are a registered shareholder and you share the same address with another of our registered shareholders, you may request delivery of a single copy of future annual reports and proxy statements at any time by calling ALLETE Shareholder Services at (218) 355-3114, or by writing to ALLETE's transfer agent, Equiniti Trust Company, Shareowner Services, Attention: Householding, P.O. Box 64854, St. Paul, MN 55164-0854.

Many brokerage firms and financial institutions have procedures for delivering a single copy of Company documents to households with multiple beneficial shareholders. If your family has one or more "street name" accounts under which you beneficially own shares of Common Stock, please contact your broker or financial institution directly if you have questions or directions concerning your "street name" account.

**Who is entitled to vote at the Annual Meeting?**

Investors who held the Company's Common Stock at the close of business on the Record Date are entitled to vote at the Annual Meeting. As of the close of business on the Record Date, there were 57,313,203 outstanding shares of Common Stock, with each share entitled to one vote.

**How many votes must be present to hold the Annual Meeting?**

The holders of a majority of the shares of Common Stock entitled to vote at the meeting must be present in person or represented by proxy to constitute a quorum, which is required to transact business at the Annual Meeting.

**What is the purpose of the Annual Meeting?**

At the meeting, shareholders will be asked to do the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.Elect a Board of ten Directors to serve for the ensuing year. The Director nominees are:

Bethany M. Owen, Susan K. Nestegard, George G. Goldfarb, James J. Hoolihan,

Madeleine W. Ludlow, Charles R. Matthews, Douglas C. Neve, Barbara A. Nick,

Robert P. Powers, and Charlene A. Thomas;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.Hold an advisory vote to approve executive compensation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.Hold an advisory vote on the frequency of future advisory votes on executive compensation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.Ratify the selection of PricewaterhouseCoopers LLP as the Company's independent registered public accounting firm for 2023; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.Transact such other business as may properly come before the meeting or any adjournments or postponements thereof.

The Board is not aware of any other matter to be presented at the Annual Meeting. If any other matters properly come before the meeting, all shares represented by valid proxies will be voted in accordance with the judgment of the appointed proxies.

To be admitted to the Annual Meeting at <u>www.virtualshareholdermeeting.com/ALE2023</u> as a shareholder, you must enter the 16-digit control number found next to the label "Control Number" on your Notice of Internet Availability, proxy card, or voting instruction form.

Item 3. To hold an advisory vote to approve executive compensation every "**ONE YEAR**;"

Unless contrary instructions are provided, all shares of Common Stock represented by valid proxies will be voted in accordance with the Board's recommendations.

**How do I vote my shares?**

You may vote your shares by proxy using any of the following methods:

![ale-20230320_g2.jpg](ale-20230320_g2.jpg)***Internet****:* Vote online at <u>www.proxyvote.com</u>.

![ale-20230320_g3.jpg](ale-20230320_g3.jpg)***Telephone****:* Vote by calling, toll-free in the U.S., (800) 690-6903.

Internet and telephone voting facilities for registered shareholders will be available 24 hours a day until 11:59 p.m. Eastern Daylight Time, on May 8, 2023. If you vote your shares on the Internet or by telephone, you do not have to return your proxy card. Please have your proxy card (or Notice of Internet Availability of Proxy Materials or the email message you receive with instructions on how to vote) in hand when you go online or use the phone to vote. You will have an opportunity to confirm your voting selections before your vote is recorded. The availability of Internet and telephone voting for beneficial owners will depend on the voting processes of your broker, bank, or other nominee. You should follow the voting instructions in the materials that you received from your nominee.

<u>By Mail</u>: If you would like to vote by mail, please request a paper proxy card in accordance with the instructions contained in the Notice of Internet Availability of Proxy Materials and then complete, sign, and date the proxy card and return it in the postage-paid envelope provided. Your proxy card must be received by May 8, 2023. For shares held in "street name," please use the voting instruction card provided by your broker, bank, or other nominee and mark, sign, date, and mail it back to your broker, bank, or other nominee in accordance with their instructions.

------

<u>Online During the Annual Meeting</u>: If you are a registered shareholder, you can vote your shares online during the Annual Meeting, although we encourage you to vote your shares in advance of the Annual Meeting even if you plan to attend the Annual Meeting. Voting your proxy electronically via the Internet, by telephone, or by mail does not limit your right to vote at the Annual Meeting.

**What is the difference between a "registered" shareholder and a "beneficial" shareholder?**

If your Common Stock is registered directly in your name with our transfer agent, Equiniti Trust Company, you are a registered shareholder, also called a shareholder of record. As a shareholder of record, you can vote your shares by proxy directly with the Company (online, by telephone, or by mail) in advance of the Annual Meeting or you can vote your shares online at the Annual Meeting.

If your Common Stock is in an account or trust held in the name of a broker, bank, or other nominee as custodian on your behalf, or in "street name," you are a beneficial owner. As a beneficial owner, you have the right to direct your broker, bank, or other nominee as to how to vote your shares. You are also invited to attend the Annual Meeting. If you wish to vote your shares at the meeting, however, you must bring a legal proxy from your broker, bank, or other nominee.

**&nbsp;&nbsp;&nbsp;&nbsp;**

**Can my broker vote my shares for me without my instruction?**

Your broker can vote your shares without instruction from you only as to Item 4, the ratification of the selection of our independent registered public accounting firm for 2023. As to all other voting items in this Proxy Statement, your broker cannot vote your shares without instructions from you.

If you do not instruct your broker to vote your shares as to Item 1, your shares will not be considered in determining the number of votes necessary for approval and will have no effect on the outcome of this proposal. If you do not instruct your broker to vote your shares a

**What vote is required to approve each proposal?** 

<u>Item 1</u>: Each Director will be elected by the affirmative vote of a majority of the votes cast with respect to that Director nominee. A majority of the votes cast means that the number of votes cast "for" the election of a nominee must exceed the number of votes cast "against" the election of that nominee. Nominees receiving more votes for their election than votes against their election will be elected. If you abstain from voting for one or more of the nominees for Director, your abstention will have no effect on the election of such Director.

<u>Item 2</u>: The advisory vote on executive compensation will be decided by an affirmative vote of a majority of the shares present or represented by proxy and entitled to vote, provided that the total number of shares voting for this proposal represents more than 25 percent of the Common Stock shares outstanding on the Record Date. If you abstain from this advisory vote, your abstention will have the same effect as a vote against this proposal. Although this is a non-binding, advisory vote, the

ECHC Committee and the Board will consider the outcome of the vote when making future executive compensation decisions.

------

<u>Item 3</u>: The advisory vote on the frequency of future advisory votes on executive compensation will be decided by an affirmative vote of a majority of the shares present or represented by proxy and entitled to vote, provided that the total number of shares voting for this proposal represents more than 25 percent of the Common Stock shares outstanding on the Record Date. Your vote in favor of one of the frequency choices, or your abstention, will have the same effect as a vote against the other frequency choices (or against all the choices in the case of your abstention). Although this is a non-binding, advisory vote, the ECHC Committee and the Board will consider the outcome of the vote when determining the frequency of future advisory votes on executive compensation.

<u>Item 4</u>: The affirmative vote of a majority of the shares present in person or represented by proxy is required to ratify the selection of PricewaterhouseCoopers as our independent registered public accounting firm for 2023, provided that the total number of shares voting for this proposal represents more than 25 percent of the shares outstanding on the Record Date. If you abstain from voting for the ratification of the selection of PricewaterhouseCoopers, your abstention will have the same effect as a vote against this proposal.

A "broker non-vote" occurs when a broker submits a proxy card for shares to the Company but does not indicate a vote on a particular matter because the broker has not received timely voting instructions from the beneficial owner with respect to that particular matter. Broker non-votes are not counted for or against any proposal. They are treated as shares not present and not entitled to vote on a particular proposal. An automated system administered by Broadridge Investor Communications Solutions, Inc. will tabulate the proxy votes.

**Can I change my vote or revoke my proxy?**

Yes. If you are a shareholder of record, you can change your vote or revoke your proxy at any time before it is voted at the Annual Meeting, either by signing and returning a proxy card with a later date or by attending the Annual Meeting and changing your vote prior to the start of the meeting. If you have voted your shares online or by telephone, you can revoke your prior online or telephonic vote by recording a different vote, or by signing and returning a proxy card dated as of a date later than your last online or telephonic vote. If you are a beneficial owner, you must contact your broker, bank, or other nominee to change your vote or revoke your proxy.

**Where can I find the voting results?**

We will announce preliminary results at the Annual Meeting and publish the results in a Form 8-K filed with the SEC within four business days after the date of the Annual Meeting.

**Who can answer additional questions?**

You are welcome to contact ALLETE Shareholder Services with any questions you may have regarding this Proxy Statement. The telephone number is (218) 355-3114. The mailing address is: ALLETE, Inc., Attention: Shareholder Services, 30 West Superior Street, Duluth, MN 55802.

As discussed on page 30, non-employee Directors are expected to own shares with a valuation equal to at least five times their annual cash retainer within five years of election. As of March 10, 2023, all independent Directors met the Common Stock ownership guideline, except: Ms. Thomas, who first became subject to the guideline in 2021, and Mr. Matthews, who first became subject to the guideline in 2022; both are making expected progress toward meeting the guideline.

Common Stock ownership guidelines applicable to NEOs are discussed on pages 30 and 50. The Board reviewed executive stock ownership in April 2022. As of March 10, 2023, all NEOs met their respective share ownership guideline, except: Ms. Owen, who was promoted to a position with a higher stock ownership guideline in 2019, and again in 2020, Mr. Morris who was promoted to a position with a higher stock ownership guideline in 2022, and Ms. Thickens, who first became subject to a stock ownership guideline with her promotion in 2019; all three are making expected progress toward meeting their guidelines.

In determining whether Directors and NEOs met the Common Stock ownership guidelines, we include deferred shares and RSUs because we believe these derivative holdings accomplish similar objectives as stock ownership, namely they encourage Directors and NEOs to have a stake in the Company and they align the Directors' and NEOs' interests with those of shareholders.

------

The following table shows the shares of Common Stock beneficially owned, as of March 10, 2023, by Directors, nominees for Director, executive officers named in the Summary Compensation Table on page 56, and all Directors, nominees for Director, and executive officers as a group. Except as otherwise indicated, the persons shown have sole voting and investment power over the Common Stock listed.

<sup>1&nbsp;&nbsp;&nbsp;&nbsp;</sup>The share amounts in this column include: (i) shares as to which voting and investment power is shared with the person's spouse: Mr. Hoolihan—12,003, Mr. Matthews—639, and Mr. Neve—9,850; and (ii) shares owned by the person as custodian for child: Ms. Johnson—60. Each Director, nominee for Director, and executive officer, individually, and all Directors, nominees for Director, and executive officers as a group, beneficially own only a fraction of one percent of the

Common Stock outstanding.

<sup>2 &nbsp;&nbsp;&nbsp;&nbsp;</sup>The amounts in the "Other" column do not represent either issued Common Stock or a right of the holder to receive Common Stock within 60 days and are not considered beneficially owned in accordance with Rule 13d-3 under the Exchange Act. The amounts are shown here because the Company includes those holdings when determining whether a Director or NEO has met their applicable stock ownership guideline. Directors are able to defer their cash and stock retainers under the Deferral Plan II. Distributions of deferred shares will be made in Common Stock.

<sup>3</sup> The stock ownership guideline amounts shown have been calculated using a Common Stock valuation of $60.31 per share, the closing price on March 10, 2023. The amount shown for non-employee Directors was determined based on the annual cash retainer in effect for Directors as of March 10, 2023. Stock ownership guidelines shown for all NEOs were determined based on the NEO's salary as of March 10, 2023.

**Pledging, Hedging, and Short Sales of Common Stock Prohibited**

The ALLETE Purchase and Sale of Company Securities Policy prohibits Directors and officers, including each NEO, from holding Common Stock in a margin account or otherwise entering into any pledge arrangement that would permit a third party to sell the securities without the Director's or officer's consent or knowledge. In addition, no Director or officer, including any NEO, may enter into any transaction that allows him or her to be insulated from the full risk or reward of Common Stock ownership (i.e., hedging) nor may a Director or officer enter into any transaction that allows him or her to benefit if the value of the Common Stock decreases (i.e., short sale).

------

 **ITEM NO. 1—ELECTION OF DIRECTORS**

**________________________________________________________________**

Ten Director nominees have been recommended by the CG Committee and nominated by the Board. Each Director elected will serve until the next annual election of Directors and until a successor is qualified and elected, or until the Director's earlier resignation or removal. If any nominee should become unavailable, which is not anticipated, the Board may provide by resolution for a lesser number of Directors, or designate substitute nominees, who would receive the votes represented by proxies.

Unless otherwise directed, all shares represented by proxy will be voted **"FOR"** the election of the ten nominees for Director named below and on the following pages.

**CORPORATE GOVERNANCE ________________________________________________________________**

ALLETE operates from a foundation of sound corporate governance practices, with a Board that provides oversight focused on ensuring that the Company is managed in a manner that builds long-term value for our shareholders, customers, employees, and communities. Our governance framework is built around a skilled, engaged Board and focused attention to our values and culture. This provides a working structure for effective decision-making, principled actions, and appropriate monitoring of risks, compliance, and performance.

The Board takes an active role overseeing ALLETE's strategy and approves the strategic direction of the Company, any changes in long term capital structure, significant transactions, and any entry into substantial new lines of business. We believe that taking the interests of our stakeholders into consideration and making decisions guided by Company values–with integrity at the foundation of all we do–are important to ALLETE's long-term success and profitability.

**Governance Documents**

ALLETE's key governance documents, including our Corporate Governance Guidelines, are available on our website at <u>www.allete.com/Governance</u>.

Our Corporate Governance Guidelines address the Board and committee responsibilities, Director selection, Board operating policies, Director compensation, expectations for Directors, Director stock ownership, and other matters. These guidelines were most recently revised in February 2023.

Each Board committee operates under its own charter. The Audit Committee Charter was last reviewed and revised in February 2022. The Executive Compensation and Human Capital Committee Charter, and the Corporate Governance and Nominating Committee Charter were each last reviewed and revised in February 2023.

------

**Director Independence**

Director independence is an essential requirement for sound governance. Our Corporate Governance Guidelines provide that a substantial majority of the Board must be independent. The Board has adopted independence standards that are consistent with the independence standards of the NYSE and the SEC. An "independent" Director is one who has no material relationship with the Company, other than as a Director, either directly or as a partner, shareholder, or officer of an organization that has a relationship with the Company.

The CG Committee provides recommendations to the Board with respect to whether an individual Director is independent, and the Board annually reviews and makes an affirmative determination of each Director's independence.

The CG Committee and the Board consider all relevant facts and circumstances in making independence recommendations and independence determinations. In addition, the Board has adopted certain categorical standards to assist in determining a Director's independence. Specifically, a "material relationship" with the Company exists and, therefore, a Director will not be independent, if any of the following applies:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.The Director is or has been employed by the Company within the last three years (other than as a former interim Chair or a former interim CEO); or the Director's immediate family member is or has been employed by the Company within the last three years as an executive officer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.The Director has received, or the Director has an immediate family member who has received, during any 12-month period in any of the last three years, more than $120,000 in direct compensation from the Company (other than Director and committee fees, pension, or other forms of deferred compensation for prior service so long as such compensation is not contingent on continued service);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.The Director is a current partner or employee of a firm that is the Company's current independent registered public accounting firm; the Director has an immediate family member who is a current partner of the Company's current independent registered public accounting firm; the Director has an immediate family member who is a current employee of the Company's current independent registered public accounting firm and who personally works on the Company's audit; or the Director or an immediate family member was, within the last three years, a partner or employee of the Company's current independent registered public accounting firm and personally worked on the Company's audit within that time;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.The Director or an immediate family member is or has been, within the last three years, employed as an executive officer of another company where any of the Company's present executive officers at the same time serves or served on that company's compensation committee;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.The Director is a current employee, or an immediate family member is a current executive officer, of a company that has made payments to, or received payments from, the Company for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $1 million, or two percent of such other company's consolidated gross revenues; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.The Director or an immediate family member has been an executive officer of a foundation, university, non-profit trust, or other tax-exempt charitable organization, within the last three years, for which contributions from the Company and its respective trusts or foundations, account or accounted for more than the greater of $1 million, or two percent of such charitable organization's consolidated gross revenue.

------

**Director Independence Determinations**

In considering the independence of the Directors, the CG Committee examined any transactions between Directors and the Company in 2022. In particular, the CG Committee considered Mr. Hoolihan's relationship to Industrial Lubricant Company (ILCO). ILCO is owned and operated by Mr. Hoolihan's immediate family members. ILCO provides lubricant products and services to one of the Company's generating facilities and to one of the Company's subsidiaries, BNI Energy, Ltd. During 2022, Company payments to ILCO totaled $603,956. The CG Committee reviewed the ILCO transactions, without Mr. Hoolihan's participation, and determined that the transactions with ILCO did not constitute a material relationship for purposes of the Company's categorical standards in determining a Director's independence. Further, Mr. Hoolihan had no personal involvement in the transactions and the transactions were not material to him or to any person or entity with whom he has an affiliation. The CG Committee concluded that Mr. Hoolihan did not have a direct or indirect material interest in the transactions. The CG Committee previously considered similar transactions that occurred in 2021 and 2020 and reached the same conclusions. Based on this, the CG Committee recommended to the Board, and the Board affirmatively determined, that these transactions did not impair Mr. Hoolihan's independence.

Applying the Company's independence standards and considering all relevant facts and circumstances in accordance with our determination process, the Board affirmatively determined that each Director, except Ms. Owen, is independent.

**ALLETE's Board of Directors**

ALLETE is overseen by a Board of Directors made up of highly qualified individuals with diverse skills, attributes, and experiences. We recognize the importance of a well-balanced Board with both the individual capabilities and the collective strengths to effectively address the Company's evolving needs and to act in the best interests of our shareholders, customers, employees, and communities.

**Board Diversity and Director Nominations**

ALLETE seeks Directors whose diverse skills, experiences, backgrounds, and perspectives will serve shareholders well and contribute to sound corporate governance. The Board values diversity and believes representation from a range of professional backgrounds, as well as a mix of gender, racial, cultural, geographic, and other diverse perspectives enhances effective governance, contributes to robust discussion, and drives successful performance by increasing understanding of the expectations and viewpoints of our investors and other stakeholders. As we continue to refresh our Board over time, we will continue to seek for consideration candidates who, among other attributes, will enhance the Board's racial and ethnic diversity.

The CG Committee regularly reviews the skills, expertise, and attributes that are important for effective governance of the Company and recommends Director candidates to the Board. The CG Committee will consider any person proposed by a Director, management, a search firm, or any shareholder. All Director candidates will be evaluated based on the criteria identified below, regardless of who proposed such person.

In selecting Director nominees, the Board considers multiple factors including: integrity, qualifications, diversity, age, skills, experience, independence, commitment to sustainability as outlined in the Corporate Sustainability Report, how the candidate's relevant experience would complement and enhance Board composition, Board succession plans, the candidate's ability and willingness to devote adequate time to Board duties, and the likelihood that they will be willing and able to serve on the Board for a sustained period. The Board considers its overall balance of perspectives, backgrounds, and experiences; as part of this, the Board will consider whether a candidate's background will enhance the Board's racial and ethnic diversity. The CG Committee will consider the candidate's independence in accordance with ALLETE's Corporate Governance Guidelines and the NYSE and SEC rules. Director nominees must be willing and able to devote adequate time and attention to Board service, must demonstrate independent thinking, a collaborative nature, and stakeholder awareness. Director nominees must have experience with business and strategic planning, as well as prior service on, or experience working closely with, a board of directors. In connection with the selection, due consideration will be given to a candidate's particular experience, including but not limited to: executive corporate leadership experience; understanding of board committee functions; understanding of generally accepted accounting principles; financial expertise (including qualification as an audit committee financial expert within the meaning of the SEC's rules); financing experience; auditing experience; human resource and executive compensation expertise; strategic planning and business development experience; experience with regulated utilities; strategic experience with renewable energy businesses or technologies; familiarity with the regions in which Company provides services; and community leadership.

The Board may engage a search firm to assist in identifying and conducting due diligence on potential Director nominees.

------

Before making contact with a potential candidate, the CG Committee will notify the Board of its intent to do so, will provide the candidate's name and background information to the Board, and will allow time for Directors to comment. The CG Committee will screen potential candidates for the Board. A majority of the CG Committee members will interview any candidate before recommending that candidate to the Board. The recommendations of the CG Committee will be timed so as to allow Board members an opportunity to interview the candidate prior to the nomination of the candidate. The Board as a whole is responsible for nominating individuals for election to the Board and for filling vacancies on the Board that may occur between annual shareholders' meetings.

A shareholder who wishes to propose a candidate should provide the person's name and a detailed background of the candidate's qualifications to the Corporate Governance and Nominating Committee, c/o Corporate Secretary, ALLETE, Inc., 30 West Superior Street, Duluth, MN 55802.

**Board Leadership**

Ms. Owen has served as Board Chair since May 2021. As Chair, Ms. Owen presides over meetings of the Board, presides over meetings of the shareholders, consults with and advises the Board and its committees on the Company's business and affairs, and performs other duties as may be assigned by the Board.

Consistent with ALLETE's Corporate Governance Guidelines, because the Board Chair is not independent, the independent Directors select an independent Lead Director on an annual basis. The Lead Director:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• presides when the Board meets in executive session;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• presides at Board meetings when the Chair is not present to lead the Board's deliberations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• serves as an *ex officio* member of each Board committee;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• serves as a liaison between the Chair and the independent Directors when necessary to provide a supplemental communication channel;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• works with the Chair to develop Board meeting agendas, schedules, and information to be provided to Directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• leads the evaluation of CEO performance in consultation with the CG Committee; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• performs other duties as requested by the independent Directors.

The Board believes that its leadership structure—a combined Board Chair and CEO, an independent Lead Director, and committees comprised of and chaired by independent Directors—is the most effective for ALLETE at this time. In reaching this determination, the Board considered factors including the Company's size, the diversity and experience of our independent Board members, Ms. Owen's industry and governance experience, the Board's effective use of the Lead Director who provides coordination and leadership for the independent Directors, and the active engagement by all Directors.

The Board has three standing committees: the Audit Committee, the Executive Compensation and Human Capital Committee, and the Corporate Governance and Nominating Committee. We anticipate that committee chairs will rotate among Directors. The Board recognizes that rotating chairs provides development for the Directors and allows a variety of perspectives in leadership positions.

**Board Role in Risk Oversight**

The Board is responsible for risk management oversight at the Company. While the Board as a whole exercises direct oversight of strategic risks and other critical risk areas with enterprise-wide significance to the Company, substantial aspects of risk oversight are delegated to Board committees and management. The Board administers its risk oversight function in a variety of ways, including through a thoughtfully designed leadership and oversight structure illustrated as follows:

---

| |
|:---|
| **Board of Directors** |
| Directly oversees ALLETE's strategy and critical risk areas with enterprise-wide significance to the Company; Reviews and discusses with management significant risks affecting ALLETE, including matters identified by<br>Board committees from within their respective oversight areas, and oversees how senior management<br>manages enterprise-level risks. |

---

---

| | | |
|:---|:---|:---|
| **Audit Committee** | **ECHC Committee** | **CG Committee** |
| Oversees: financial reporting processes, business conduct, tax, and other financial risks; the appointment, evaluation, and oversight of the Company's independent registered public accounting firm; the internal audit function; legal and regulatory compliance, significant legal matters; insurance programs; market and credit risks; and physical and cybersecurity risks. | Oversees: the design and administration of executive compensation policies and programs and ensures that executive compensation programs link to ALLETE's sustainability strategy. Also has primary responsibility for assisting the Board with oversight of ALLETE's talent strategy and programs to attract, develop, engage, and retain talent; ALLETE's safety policies, and strategies; DE&I initiatives; and human capital risks. | Oversees: Board structure and function, including corporate governance risks; Board independence; Board succession and composition; CEO succession planning; code of ethics; and political contributions and lobbying policy. Also has primary responsibility for assisting the Board with oversight of ESG reporting. |

---

| **Senior Management** |
| ALLETE's CEO, CFO, Chief Legal Officer, Chief Risk Officer, and other senior leaders are responsible for implementing and supervising enterprise risk-management processes. Management confers with and reports to the Board and its committees with respect to key enterprise risk indicators, risk management and mitigation practices, and other significant matters. |

---

---

| | |
|:---|:---|
| **Internal Audit Function** | **Enterprise Risk Management Program** |
| Directly overseen by the Audit Committee. Prepares audit plans that are reviewed and approved by the Audit Committee at least annually.  | Ensures that strategic goals align with ALLETE's mission, vision, and values and that decision-making and strategy execution includes adequate consideration of the associated risks. Includes the ALLETE Risk Management Committee, made up of executive officers and ALLETE's Chief Risk Officer, which regularly identifies and assesses key risks and defines procedures for mitigating and reporting significant risks.  |

---

This tiered and structured approach provides a comprehensive framework designed to protect the interests of our shareholders and other stakeholders.

------

**Code of Business Conduct and Ethics**

ALLETE has adopted a written Code of Business Conduct (which includes our code of ethics) that applies to all Directors and employees and officers, including the CEO and the CFO, who is also the Company's principal accounting officer. The Code of Business Conduct also applies to our contractors, suppliers, and vendors. ALLETE's Code of Business Conduct is available on our website at <u>www.allete.com/governance</u>. Any amendment to the Code of Business Conduct, or waiver the Code of Business Conduct involving a Director or NEO, will be published on ALLETE's website promptly following the date of such amendment or waiver.

**Shareholder Engagement**

We seek out meaningful engagement with shareholders to understand their perspectives on corporate governance, executive compensation, and other issues that matter to investors. We engage with shareholders throughout the year to provide visibility and transparency into our businesses and our financial and operational performance, to listen to shareholders' perspectives and understand shareholders' expectations of us, to share our environmental and sustainability strategy and accomplishments, and to receive feedback on our communications and disclosures to shareholders.

Throughout the year, senior management and our investor relations team meet with analysts and institutional investors to review financial and other business and strategic issues, as well as to solicit input, provide perspective on Company policies and practices, and answer questions. We participate in investor conferences, other formal events and groups, and also in one-on-one meetings. We also engage with representatives of our large shareholders to discuss our programs and learn about the key areas on which their clients are focusing. During 2022, we contacted shareholders owning approximately 59% of our outstanding Common Stock, resulting in substantive engagements with the holders of approximately 38% of our outstanding shares. We discussed topics including: ALLETE's financial and operational performance; growth initiatives; strategy updates; dividend practices; executive compensation practices; and corporate governance practices, as well as ESG strategy, performance, and reporting.

The Board receives regular reports from senior management and ALLETE's investor relations team about shareholder engagements and what our investors are telling us about topics that matter to them.

**Political Contributions and Lobbying**

ALLETE believes that public policy engagement is an important part of responsible corporate citizenship. We participate in this process in accordance with good corporate governance practices. ALLETE's policy regarding political contributions and lobbying is overseen by the CG Committee. Our policy governs the Company's corporate contributions to organizations registered under Section 527 of the Internal Revenue Code and ballot measures or initiative campaigns that impact the Company's business. On the state level, employees have the opportunity—on a voluntary basis—to make political contributions through political action committees (PACs). Coordination of lobbying activities is done through ALLETE's Safety and External Affairs Officer with the prior approval of senior management. All political contributions and lobbying activities are done in compliance with all laws and regulations.

ALLETE's Political Contributions and Lobbying Policy is available at on our website at

<u>www.allete.com/Governance</u>.

**Sustainability, ESG Oversight, and Corporate Responsibility** 

Our commitment to sustainability is led and supported through strong Board leadership, intentional management focus, and sound corporate governance practices. The Board oversees ALLETE's strategy, Enterprise Risk Management program, and ESG-related matters, including the evaluation of sustainability-related risks and opportunities, all in a manner designed to drive performance for our shareholders and other stakeholders. We honor our commitments to our customers, our communities, and the climate by acting to advance sustainability goals. Corporate responsibility is integrated into our governance processes and is embedded in our strategy and our core values, namely: *integrity, safety, people,* and *planet*.

ALLETE recognizes that impacts from human activity, including climate change, are real, and we are taking action to transform the nation's energy landscape through sustainable solutions. ALLETE is committed to leading the path toward a carbon-free energy future. We are poised to add significantly more clean energy in the coming years while ensuring reliable, resilient energy delivery to our customers. Our overall strategy is to enhance and grow our companies by providing sustainable energy solutions to meet changing societal expectations and evolving regulations, and all of our companies play an important role in this strategy. We also recognize that the transition to a clean-energy future will only be truly successful if it is just and equitable, with new opportunities and investments designed to give everyone an opportunity to thrive.

Each business units' mission, customer mix, and regulatory status are all key drivers in determining the carbon reduction strategies employed. Our "sustainability in action" growth strategy involves: continuing to reduce carbon emissions, delivering cleaner energy sources to our customers, strengthening the electric grid to accommodate for more intermittent renewable resources, and implementing innovative solutions to enhance resiliency for all our businesses. ALLETE's comprehensive ESG program also includes a committed social focus, which includes advancing DE&I in our workforce, supply chain, and community giving, outreach and engagement with tribal nations, health and wellness safety initiatives, as well as enhanced sustainability communication and disclosures.

The CG Committee oversees the process related to ESG matters and receives regular updates from senior management on such matters. During 2022, management actively engaged with investors and other key stakeholders to discuss ALLETE's sustainability strategy and initiatives and to gain insights into stakeholders' perspectives about sustainability and corporate responsibility, and how to effectively measure, communicate, and disclose our efforts. In January 2023, we released an update to our Corporate Sustainability Report, which can be found at our website <u>www.allete.com/sustainability</u>.

**Meetings of Independent Directors**

At each regularly scheduled Board meeting, the independent Directors meet in executive session for discussion without management present. These meetings are chaired by the Lead Director. The Board has direct access to management and meets with members of management individually when it deems appropriate.

**Board Contact with Management and Independent Advisors** 

Executive officers and other management employees are regularly included in Board and committee meetings, as deemed appropriate. Directors may meet individually with executive officers and other management employees.

The Board and its committees also retain their own independent advisors at their discretion.

**Board and Committee Evaluations**

The Board and its committees undertake self-evaluations on an annual basis.

The Board's self-evaluation includes soliciting opinions from the Directors about topics related to Board effectiveness including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The sufficiency of and timeliness of briefing materials provided to Directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The content and conduct of Board meetings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The adequacy of time allocated to, and the quality of, presentations and discussions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Board's access to management;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Board's understanding of issues;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Board's consideration of shareholders' interests in making decisions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The overall mix of characteristics and skill sets represented by Board members; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Any area previously identified by Board members as requiring improvement.

The assessments are used to improve Board performance and effectiveness.

Each Board committee's self-evaluation addresses matters the committee considers relevant to its performance, including a review and assessment of the adequacy of the committee's charter. A report on each committee's self-evaluation is presented to the Board.

------

**Meeting Attendance**

Our Corporate Governance Guidelines provide that Directors are expected to regularly attend Board meetings and meetings of the committee or committees on which they serve. The Board held nine meetings during 2022 and each Director attended every Board meeting. Each Director attended

100 percent of the aggregate number of meetings held in 2022 by the committees on which they served. Mr. Matthews, who was elected to the Board on July 6, 2022, attended every Board meeting held in 2022 since becoming a Director; Mr. Matthews also attended every meeting of the committee on which he serves that was held in 2022 since he became a Director.

Directors standing for election are expected to attend the Annual Meeting. Each Director attended the 2022 Annual Meeting.

**Director Continuing Education**

Ongoing development is an important aspect of governance. In addition to the frequent updates on corporate governance practices and requirements provided by the Company, Directors are asked to attend educational seminars, and to share their experiences with the other Directors. During 2022, Directors attended educational courses presented by outside entities on a variety topics including:

financial reporting; accounting; corporate taxation; addressing urgent climate change risks, cyber security risks and mitigation; resilient leadership; key strategic issues facing power and utility industries; challenges and opportunities associated with electric vehicles; information technology trends; and delivering shareholder value through strategic oversight.

In addition, Directors attended educational presentations hosted by the Company in 2022 covering the following topics: regional economic development; global and regional mining industry updates, including decarbonization trends, ESG initiatives, technological advancements, and domestic and international geopolitical industry trends; water treatment and hydroelectric operations; the Infrastructure Investment and Jobs Act and the Inflation Reduction Act of 2022 in relation to Company strategy; energy and utility sector shareholder landscape; and strategic and market developments in the electric utility industry.

**Share Ownership Guidelines**

The CG Committee has determined that Directors and executive officers should have an equity interest in the Company. The CG Committee believes that such equity ownership aligns the Directors' interests with those of the Company's shareholders. Accordingly, the Board has adopted stock ownership guidelines.

Directors are expected to own at least 500 shares of Common Stock prior to their election to the Board. Further, within five years of their election to the Board, non-employee Directors are expected to own shares worth at least five times the amount of the annual cash retainer paid to Directors. Executive stock ownership guidelines are discussed in the CD&A on page 33.

The CG Committee regularly reviews the stock ownership guidelines and may recommend changes to the Board as it deems appropriate.

------

**Related Person Transactions**

The Board recognizes that in the ordinary course of business, transactions may occur between ALLETE and its subsidiaries and entities with which some of our Directors and officers are or may have been affiliated. Such transactions are evaluated in accordance with ALLETE's Related Person Transaction Policy, which was last reviewed and approved by the Board in July 2022, and is available at <u>www.allete.com/Governance</u>.

Related persons include Directors, Director nominees, executive officers, and five percent shareholders, as well as their immediate family members and any entity controlled by these individuals or in which these individuals have a substantial financial interest.

The Related Person Transaction Policy applies to a financial transaction or arrangement, or a series of similar transactions or arrangements, which exceeds $25,000 annually or $6,250 quarterly, in which a related person has or will have a direct or indirect material interest.

Transactions between the Company and a related person generally require advance approval by the CG Committee. If a new situation arises where advance approval is not practical, it is discussed with the Chair of the CG Committee, or with another CG Committee member designated by the committee; an appropriate response might include subsequent ratification by the CG Committee.

The CG Committee also periodically reviews and assesses related person relationships to ensure ongoing fairness to the Company. Any member of the CG Committee who has an interest in a transaction will abstain from voting, but may participate in the discussion if invited to do so by the

CG Committee Chair, or the Lead Director if the CG Committee Chair has an interest in the transaction.

The CG Committee considers factors it deems relevant in determining whether to approve a related person transaction, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the extent of the related person's interest in the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the availability of comparable products or services from non-related persons;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the transaction is on terms comparable to those that could be obtained in an arm's-length dealing with an unrelated third party;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the business reasons to enter into the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the transaction could impair the independence of a Director;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the annual amount involved exceeds the greater of $200,000 or 5 percent of the recipient's gross revenues for the year; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the transaction would present an improper conflict of interest, taking into account the size of the transaction, the overall financial position of the related person, the direct or indirect relationship of the related person, and the ongoing nature of any proposed relationships.

**Communications between Shareholders and Other Interested Parties and the Board**

We believe that it is an important aspect of corporate governance to facilitate direct communication between the Board and shareholders and other stakeholders. Shareholders and other stakeholders may communicate directly with our Board, with any specified group of Directors, such as a Board committee or independent Directors, or with any individual Director. Such communications should be in writing and addressed to the Lead Director, c/o Corporate Secretary, ALLETE, Inc., 30 West Superior Street, Duluth, MN 55802. Communications that are determined to be primarily commercial in nature, such as business solicitations and advertisements, will not be forwarded to the Board.

**ITEM NO. 2—ADVISORY VOTE TO APPROVE EXECUTIVE COMPENSATION ________________________________________________________________**

We are asking our shareholders to cast a non-binding, advisory vote approving compensation for our NEOs as reported in this Proxy Statement.

ALLETE's executive compensation program is designed to enhance shareholder value while attracting and retaining experienced, qualified executives. To fully understand ALLETE's 2022 executive compensation, we encourage you to read the CD&A, starting on page 33 as well as the compensation tables and narrative disclosures that follow the CD&A. Those sections describe how our compensation programs are designed to achieve ALLETE's compensation objectives and provide detailed information on the 2022 compensation of our NEOs. We believe our executive compensation program reflects a pay-for-performance philosophy and is aligned with shareholders' long-term interests.

This proposal, commonly known as "say-on-pay," is required under Section 14A of the Exchange Act. Although this say-on-pay vote is advisory and not binding on the Company, the ECHC Committee and the Board will review the voting results and will take the outcome of the vote into account when considering future executive compensation decisions.

Although the ECHC Committee and the Board will consider the outcome of the advisory shareholder vote on say-on-pay frequency in Item No. 3 of this Proxy Statement, we expect the next advisory shareholder say-on-pay vote will occur at the 2024 Annual Meeting.

**The Board recommends a vote "FOR" the advisory vote to approve executive compensation.**

**2022 Performance for Incentive Compensation**

NEOs have a significant portion of their compensation tied to Company performance. Annual incentives focus on achieving annual financial, strategic, operational, and safety goals. Long-term incentives facilitate stock ownership and reward long-term growth and profitability. As explained in this CD&A, ALLETE's 2022 performance directly affected each NEO's 2022 compensation.

<u>Annual Incentive Compensation Performance</u>

Annual incentives reward shorter-term strategic goals as well as operational and safety accomplishments, all of which are tied to ALLETE's values. Our AIP rewards one-year financial performance measured by net income and cash from operating activities, subject to certain adjustments that are described in more detail starting on page 43. To calculate performance relative to the financial goals for annual incentive purposes, at the beginning of the performance period, the ECHC Committee established specific adjustments and also determined that it would evaluate, on a case-by-case basis, the impact of discrete, non-recurring events that might occur during the plan year.

As disclosed in ALLETE's Form 10-K for the year ended December 31, 2022, Net Income Attributable to ALLETE for the year ended December 31, 2022, prior to adjustment, was $189.3 million (compared to $169.2 million for 2021). As described in detail starting on page 44, for AIP purposes, Net Income Attributable to ALLETE was increased by an overall $10.72 million to reflect the following adjustments:

(1) decreased net income to exclude ALLETE Properties financial results, (2) increased net income to reflect the strategic decision to defer into 2023 a solar project budgeted for 2022; (3) increased net income to reflect the reserve adjustment following the Minnesota Power rate case outcome in 2022; and (4) increased net income to capture post-acquisition operations of New Energy, with a corresponding decrease to net income to reflect acquisition activities.

As disclosed in ALLETE's Form 10-K for the year ended December 31, 2022, Cash from Operating Activities for the year ended December 31, 2022, prior to adjustment, was $221.3 million (compared to $263.5 million for 2021). As described in detail on page 45, for AIP purposes, cash from operating activities was increased by $114.82 million to reflect: (1) the exclusion of cash associated with ALLETE Properties operations; (2) the exclusion of cash to reflect timing of accounting for the Minnesota Power fuel adjustment clause true-up; (3) the inclusion of cash to reflect ACE's build-own-transfer construction projects included in inventory; and (4) the inclusion of cash associated with the acquisition of New Energy.

In addition to financial metrics, the annual incentive also measures performance tied to strategic, operational, and safety goals**.** Strategic goals vary from year to year, but consistently incorporate our ESG objectives, growth objectives, operational improvements for our businesses, and the evolving needs of our customers and other stakeholders. Operational goals are tied to ALLETE's reliability performance and safety goals are tied to injury-prevention awareness and safety performance. For 2022, the ECHC Committee determined that the Company's strategic performance fell between target and superior based on the Company's performance in addressing customer competitiveness and advancing sustainability. The ECHC Committee determined that both the Company's operational and safety goals performance fell between threshold and target.

As shown in the following chart, financial results along with performance on strategic, operational and safety goals resulted in an ALLETE annual incentive payout for 2022 that equaled 104.2 percent of target (compared to 115.3 percent in 2021).

<u>Long-Term Incentive Compensation Performance</u>

Long-term incentives reflect performance over multi-year periods. PSAs awarded under the LTIP reward TSR relative to peer-group companies and EPS CAGR, both over a three-year period.

ALLETE's TSR for the three-year period ended December 31, 2022, was negative 10.3 percent, ranking us in the second percentile among the peer group, which was below threshold and resulted in no payout for TSR-related PSAs that were granted in 2020. ALLETE's EPS CAGR for the three-year period ended December 31, 2022, was negative two percent, which was also below threshold and resulted in no payout for the EPS CAGR-related PSAs that were granted in 2020.

**2022 Compensation Decisions**

Our 2022 executive compensation program remained materially consistent with prior years. The ECHC Committee based its compensation decisions on business factors, peer company compensation data, and pay-for-performance compensation analysis from Pearl Meyer, its independent compensation consultant. The ECHC Committee also considers each NEO's role, their performance, and other relevant factors, including the most recent shareholder advisory vote on executive compensation.

The ECHC Committee increased base salaries for all NEOs in 2022, except for Mr. Adams who retired in June 2022. Ms. Owen's base salary increased by eight percent in recognition of her performance in the CEO role to which she was promoted in 2020 and to bring her compensation closer to the market median. Mr. Morris received base salary increases in 2022 totaling 24 percent in recognition of his promotion to Senior Vice President and CFO and to bring his compensation closer to market median. Ms. Johnson received base salary increases in 2022 totaling 11 percent in recognition of her new role as ALLETE Vice President and President of ALLETE Clean Energy and to bring her compensation closer to the market median. Ms. Thickens and Mr. Cutshall each received base salary increases in 2022 totaling 13 percent due to expanded responsibilities and to bring compensation closer to the market median.

AIP target opportunities were increased in 2022 for Ms. Owen, Mr. Morris, Ms. Thickens, and Ms. Johnson; LTIP target opportunities were increased in 2022 for all NEOs, except for Mr. Adams. These increases reinforced the alignment of pay and performance, and brought their total target compensation closer to the market median. These annual incentive opportunities and the total target long-term incentive opportunity increases were as shown below:

|  |  |  | Mr. Cutshall | $200000 | $175000 |

---

In each case, the total long-term incentive opportunity increase was allocated 75 percent to target PSA opportunity (Ms. Owen–$112,500 increase, Mr. Morris–$56,250 increase; Ms. Thickens–$18,750 increase, Ms. Johnson–$18,750, and Mr. Cutshall–$18,750 increase) and 25 percent to RSUs

(Ms. Owen–$37,500 increase, Mr. Morris–$18,750 increase; Ms. Thickens–$6,250 increase,

Ms. Johnson–$6,250 increase, and Mr. Cutshall–$6,250 increase).

The 2022 changes described in this section better aligned the NEOs' total compensation with that of ALLETE's peer companies; total compensation, however, remained below the market median for all NEOs.

**PROCESS FOR DETERMINING EXECUTIVE COMPENSATION**

The ECHC Committee establishes our executive compensation philosophy and objectives and oversees the administration of our executive compensation programs. The ECHC Committee sets the CEO's compensation, which is reviewed and ratified by the Board without the CEO's participation. In setting the CEO's compensation, the ECHC Committee considers the Board's annual evaluation of the CEO's performance, which assesses performance relative to a broad spectrum of desired leadership and effectiveness attributes established by the Board. The ECHC Committee also compares the CEO's compensation to the compensation of CEOs at other investor-owned electric utilities. Compensation benchmarking data is adjusted for the Company's size as measured by revenue and provides a market context for the ECHC Committee's decisions. The ECHC Committee also approves the compensation of the other NEOs after considering the CEO's recommendations regarding such compensation.

At the beginning of each year, the ECHC Committee, with the CEO's recommendation, approves performance goals and measures, award dates, performance or vesting periods, and forfeiture provisions for annual and long-term incentive awards.

As part of our ongoing commitment to monitor pay-for-performance alignment, in October 2022, the ECHC Committee reviewed Pearl Meyer's 2021 pay-for-performance analysis, which confirmed our view that our executive compensation programs contain appropriate elements that are linked to performance and are balanced, fair, and competitive.

**Role of Management**

For all NEOs, the CEO makes compensation recommendations to the ECHC Committee based, in part, on each NEO's experience and responsibility level and the CEO's assessment of the NEO's performance. The CEO works with each NEO to identify individual goals that are aligned with strategic objectives within each NEO's scope of responsibility. The CEO reviews each NEO's performance during the year identifying accomplishments, areas of strength, and areas for development. The CEO bases her evaluation on her knowledge of the NEO's performance, discussions with each NEO about their self-assessment, and on the executive compensation studies described on the following page. The CEO also recommends to the ECHC Committee financial and non-financial performance measures and target opportunities under the Company's incentive compensation plans.

**Compensation Consultant Independence**

The ECHC Committee's independent compensation consulting firm for 2022 was Pearl Meyer. Pearl Meyer is engaged by, and reports directly to, the ECHC Committee. The ECHC Committee has the sole authority to hire or terminate its compensation consultant. It is the ECHC Committee's policy that its Chair pre-approve any additional services its independent compensation consultant performs for management. The ECHC Committee reviewed and confirmed Pearl Meyer's independence in 2022.

------

**Executive Compensation Studies**

Annually, the ECHC Committee reviews the peer group that ALLETE uses for compensation benchmarking purposes. Compensation benchmarking is based on published salary surveys and proxy statement data from compensation benchmarking peer companies. Because there is a strong correlation between executive compensation pay levels and company size, the ECHC Committee compares executive pay levels with those at companies that are similar in size to ALLETE as measured by market capitalization and revenue. ALLETE's compensation peer group was made up of a subset of all the companies in the EEI Stock Index in 2021, which is the group used to determine the Company's relative TSR under the LTIP. Even within this subset, however, the companies range in size significantly. Accordingly, the compensation data is size-adjusted to establish appropriate market compensation comparisons for ALLETE. In 2021, the ECHC Committee approved the following 15-company peer group for 2022:

---

| | | |
|:---|:---|:---|
| **Compensation Benchmarking Peer Group** | **Compensation Benchmarking Peer Group** | **Compensation Benchmarking Peer Group** |
| Alliant Energy Corporation | MDU Resources Group, Inc. | Otter Tail Corporation |
| Avista Corporation | MGE Energy, Inc. | PNM Resources, Inc. |
| Black Hills Corporation | NiSource, Inc. | Pinnacle West Capital Corporation |
| Hawaiian Electric Industries, Inc. | NorthWestern Corporation | Portland General Electric Company |
| IDACORP, Inc. | OGE Energy Corp. | Unitil Corporation |

---

During 2020, El Paso Electric Company was acquired and is no longer a publicly traded utility, and is no longer included in ALLETE's compensation benchmarking peer group. With El Paso Electric Company removed from the peer group, NiSource, Inc. was added to maintain a comparison group size that was aligned with Pearl Meyer's recommendation.

In October 2021, the ECHC Committee directed Pearl Meyer to conduct two compensation benchmarking studies for ALLETE: one for the CEO and another for the other NEOs. These studies provided a basis for compensation recommendations made in 2022.

The CEO benchmarking study compared Ms. Owen's compensation to an external market using size-adjusted data from published surveys and compensation data disclosed in the proxy statements of the 15-company peer group. The study also analyzed CEO pay-for-performance practices and effectiveness. The Pearl Meyer report indicated that ALLETE's CEO compensation elements were consistent with the compensation elements generally provided to CEOs. The report further indicated that Ms. Owen's base salary, annual incentive opportunity, and long-term incentive opportunity were each below the 25th percentile of market median. In setting the CEO's compensation for 2022, the ECHC Committee also considered Ms. Owen's tenure in the position.

Pearl Meyer compared the other NEO's base salaries and annual and long-term incentive opportunities to market data using the same survey sources and proxy statement data used in the CEO analysis. The Pearl Meyer report indicated that base salaries, annual incentive opportunities, and long-term incentive opportunities for the other NEOs were, to varying degrees, below market median. In addition to relying on the independent analysis for the other NEOs, the CEO and the ECHC Committee also considered each NEO's specific roles within the organization and tenure in their position.

Using these processes, and taking into account performance and new roles and responsibilities, where applicable, the ECHC Committee made the following determinations in 2022: (1) each NEO's compensation included appropriate elements; (2) Ms. Owen's base salary, AIP target opportunity, and LTIP target opportunity should be increased; (3) Mr. Morris and Ms. Thickens should receive increases in base salary, AIP target opportunity, and LTIP target opportunity; (4) Ms. Johnson should receive an increase in base salary, AIP target opportunity, and LTIP target opportunity and, in light of her new role, her AIP opportunity should be tied 75% to ACE performance goals and 25% to ALLETE performance goals; and (5) Mr. Cutshall's base salary and LTIP target opportunity should be increased.

------

**HOW WE LINK EXECUTIVE PAY TO PERFORMANCE**

A significant portion of our NEOs' compensation is tied to Company performance. Annual incentives focus on achieving annual financial, strategic, operational, and safety goals. Long-term incentives reward long-term profitability, facilitate stock ownership, and provide an incentive to remain employed with the Company.

Total compensation generally increases as position and responsibility increase; at the same time, a greater percentage of total compensation is tied to performance, and therefore at risk, as reflected in our NEOs' annual and long-term incentive opportunities.

We consider market data and Pearl Meyer's advice in setting executive compensation. We establish market ranges for our NEOs' compensation using data from investor-owned electric utilities. In setting individual compensation, we consider experience in the position, performance, job responsibilities, and relative role among the executive management group. If market data were insufficient to establish a range for a specific position, we would also consider internal equity among our NEOs, taking into account the relative responsibilities for each position.

We generally set compensation so that when target performance is achieved under the Company's incentive compensation plans, total compensation is near the market median of ALLETE's compensation peer group. Consistent with our pay-for-performance philosophy, NEOs earn higher compensation when actual performance exceeds target goals. Conversely, when the Company does not meet target goals, total compensation will generally fall below the median.

2022 total compensation opportunity for the NEOs was divided between base salary and incentive opportunities. The charts below illustrate the breakdown of compensation elements expressed as a percentage of total target compensation:

![ale-20230320_g26.jpg](ale-20230320_g26.jpg)![ale-20230320_g27.jpg](ale-20230320_g27.jpg)

The chart on the right reflects an average, for all NEOs except the CEO, of the percentage of total target compensation that is represented by each compensation element. For both charts, total target compensation is calculated using the NEOs' 2022 target opportunities for annual and long-term incentives and base salary as of December 31, 2022, except for respect for Mr. Adams whose base salary is as of his retirement in June 2022.

------

**Annual Incentive Awards**

At the beginning of each year, the ECHC Committee, with the CEO's recommendations, approves performance measures and targets for the annual incentive awards, as well as individual target award opportunities. The ECHC Committee has discretion to establish the terms of annual incentive awards and also the ability to reduce, increase, or eliminate awards, regardless of whether applicable performance goals have been achieved. The ECHC Committee sets annual incentive opportunity levels such that if the Company achieves target goals, the combination of salary and annual incentives will result in total cash compensation near the market median for ALLETE's compensation peer group.

------

<u>ALLETE AIP Financial Goals</u>

The 2022 AIP financial measures, established at the beginning of the 2022 plan year, were net income (weighted at 50%) and cash from operating activities (weighted at 20%). The ECHC Committee selected net income because it is a widely-used financial performance measure that reflects the combination of revenue generation and expense management. Cash from operating activities was selected because it indicates the Company's ability to generate funds internally for capital projects, to repay debt, and to pay dividends and interest. Both measures also can affect the Company's stock price.

With respect to both the Net Income and Cash from Operating Activities metrics, the ECHC Committee established specific exclusions and adjustment guidelines at the beginning of the performance period.

<u>ALLETE AIP Strategic, Operational, and Safety Goals</u>

AIP also rewards strategic, operational, and safety performance. Each year, the ECHC Committee reviews the allocation between financial goals and strategic, operational, and safety goals. For 2022, our strategic, operational, and safety goals remained at a combined 30 percent of the overall opportunity and the achievement of these goals is measured independently of the financial goals. Therefore, it would have been possible to earn an annual incentive payout based on achieving strategic, operational, and safety goals even if financial goals had not been met.

Strategic, operational, and safety goals are linked to strategic, operational, and safety objectives and are also aligned with ALLETE's core values: *integrity, safety, people*, and *planet*.

ALLETE's 2022 strategic goals were to advance customer competitiveness, advance transmission strategy, and advance sustainability in all dimensions. Specific sustainability goals encompassed the following: continuing to reduce carbon emissions; implementing solar projects; advancing DE&I in our workforce, supply chain, communications, customers, and community giving; and enhancing sustainability communication and disclosures. Our 2022 operational goals were designed to demonstrate ALLETE's commitment to customer service as measured by goals relating to system reliability. Specifically, operational goals focused on system reliability and were measured quarterly by the System Average Interruption Duration Index, System Average Interruption Frequency Index, and Customer Average Interruption Duration Index relative to the EEI utilities' three-year average results. Safety goals were designed to demonstrate continuous safety improvement, which we measure based on both leading and lagging indicators. Safety goals included tracking the number and severity of incidents recorded with the Occupational Safety and Health Administration and implementing proactive safety measures designed to support "zero injury" efforts, such as the ALLETE Moves stretching program and leadership safety conversations. An employee fatality, or a willful disregard of an environmental, reliability, or Federal Energy Regulatory Commission regulation or standard, would result in a reduction to, or non-payout of, safety goals.

The CEO, with input from senior management, reports the progress made on strategic goals and operational and value goals to the ECHC Committee. The ECHC Committee then determines the extent to which performance targets have been achieved.

<u>2022 AIP Results</u>

All NEOs, except Ms. Johnson, earned 104.2 percent of their respective 2022 target annual incentive opportunity (compared to 115.3 percent in 2021).

To calculate the financial goals for AIP purposes, the ECHC Committee established specified exclusions and adjustment guidelines at the beginning of the plan year. The ECHC Committee also determined at the beginning of the plan year that it would evaluate on a case-by-case basis the effect of discrete, non-recurring events that might occur during the plan year.

------

As disclosed in ALLETE's Form 10-K for the year ended December 31, 2022, prior to adjustment, Net Income Attributable to ALLETE was $189.3 million (compared to $169.2 million for 2021). That amount was then increased by an overall $10.72 million, in accordance with the ECHC Committee's predetermined exclusions and its guidelines for evaluating, on a case-by-case basis, the impact of discrete, non-recurring events that occur during the plan year, to reflect the following adjustments to net income for AIP purposes: (1) the exclusion of ALLETE Properties financial results (decreased by

$4.19 million); (2) the strategic decision to defer into 2023 a solar project budgeted for 2022 (increased by $5.03 million); (3) a reserve adjustment following the Minnesota Power rate case outcome in 2022 (increased by $12.3 million); and (4) acquisition activities and post-acquisition operations of New Energy (decreased by $2.42 million). After these exclusions, 2022 net income for AIP purposes was slightly above target at $200.0 million.

As disclosed in ALLETE's Form 10-K for the year ended December 31, 2022, Cash from Operating Activities for the year ended December 31, 2022, prior to adjustment, was $221.3 million (compared to $263.5 million for 2021). That amount was then increased by an overall $114.82 million in accordance with the ECHC Committee's predetermined exclusions and its guidelines for evaluating, on a

case-by-case basis, the impact of discrete, non-recurring events that occur during the plan year, to reflect the following adjustments to cash from operating activities for AIP purposes: (1) ALLETE Properties operations (decreased by $4.85 million); (2) the timing of accounting for the Minnesota Power fuel adjustment clause true-up (decreased by $15.07 million); (3) ACE's build-own-transfer construction projects that are included in inventory (increased by $117.95 million); and (4) post-acquisition operations of New Energy (increased by $16.79 million). After these adjustments, 2022 cash from operating activities for AIP purposes was slightly above threshold at $336.1 million.

With respect to strategic, operational, and safety goals we achieved a combined level that fell between target and superior.

The AIP results were calculated as follows:

<sup>1&nbsp;&nbsp;&nbsp;&nbsp;</sup>Payout is expressed as a percentage of the NEO's annual incentive target opportunity.

Ms. Johnson's 2022 AIP performance goals, weighting, and measures were divided between the ALLETE AIP program described above and the ACE program. Ms. Johnson earned 87.3 percent of her 2022 target annual incentive opportunity. Ms. Johnson was named ALLETE Vice President and ACE President in August 2022. For the period January through August 2022, Ms. Johnson's AIP award was tied 100 percent to ALLETE's performance goals, which paid out at 104.2 percent of target opportunity; for the period September through December, 25 percent of Ms. Johnson's award was tied to ALLETE goals and 75 percent of her award was tied to ACE performance goals, which paid out at 36.6 percent of target opportunity. ACE's net income and return on capital results were below threshold (resulting in no payout) and ACE's strategic and operational goals were achieved at below-target levels (resulting in a 20.8 percent payout). The ACE 2022 annual incentive goals, weighting, measures, and results were as follows:

<sup>1</sup> Payout is expressed as a percentage of annual incentive target opportunity.

<sup>2&nbsp;&nbsp;&nbsp;&nbsp;</sup>Threshold net income was set at 90 percent of ALLETE's budgeted net income, target was set at budget, and superior was set at 110 percent of budget. Net income for annual AIP calculation purposes is described in more detail starting on page 44.

<sup>3&nbsp;&nbsp;&nbsp;&nbsp;</sup>Threshold net income was set at 90 percent of ACE's budgeted net income, target was set at budget, and superior was set at 110 percent of budget. ALLETE net income for AIP calculation purposes is described in more detail above.

<sup>4&nbsp;&nbsp;&nbsp;&nbsp;</sup>Threshold return on capital net income was set at ACE's budgeted return on capital, target was set at 105 percent of budget, and superior was set at 110 percent of budget. Return on capital for AIP purposes is calculated by adding ACE's after-tax interest expense to ACE's net income and dividing that sum by ACE's debt and equity.

The ECHC Committee believes that the AIP provides appropriate motivation and does not encourage excessive business risks because it has multiple goals that align with the objectives of different stakeholders (e.g., shareholders, customers, regulators, and employees). The annual incentive provides payment opportunity levels that are market-competitive, and includes a cap on the maximum award amount.

**Long-Term Incentive Awards: PSAs and RSUs**

We use long-term incentive compensation to reward executives for achieving business objectives that are designed to grow long-term shareholder value. The time-vesting and forfeiture provisions associated with long-term incentive compensation also encourage NEOs to stay with the Company. Long-term incentive compensation elements consist of PSAs and RSUs.

The ECHC Committee grants the PSAs and RSUs under the LTIP at the beginning of each year. Although the ECHC Committee can make additional grants at other times of the year, it did not do so in 2022 for any NEO with the exception of an additional grant for Mr. Morris due to his promotion to CFO. We do not time equity awards to the release of material, non-public information. ECHC Committee meeting schedules are generally set six months prior to the start of the calendar year.

<u>Performance Share Awards (PSAs)</u>

PSAs reward executives for performance over a three-year period. Rewarding executives for creating long-term shareholder value links pay to performance.

For all outstanding performance periods, performance is measured, in whole or in part, by ALLETE's TSR (i.e., the investment return for a share of Common Stock, assuming full dividend reinvestment) relative to a group of peer companies. The ECHC Committee selected relative TSR because it measures the value shareholders realize from their investment in Common Stock as compared to investment opportunities available in comparable companies. Beginning with the 2020-2022 performance period, performance also was measured by EPS CAGR. The ECHC Committee selected EPS CAGR because it measures, in absolute terms, how the Company's earnings per share over the three-year period compares to our established long-term growth objectives.

The performance period begins on the first day of the three-year performance period. The payment amount with respect to any award is determined at the end of the three-year period. In 2022, NEOs were granted PSAs for the three-year performance period beginning on January 1, 2022, and ending on December 31, 2024.

For the 2022-2024 performance period, the ECHC Committee set target relative TSR at the

50th percentile among the peer group, with threshold set at the 30th percentile, and superior set at the 85th percentile. If ALLETE's relative TSR percentile at the end of the performance period falls below threshold, no PSAs will be earned. Straight-line interpolation will be used to determine earned awards based on a relative TSR percentile result between threshold, target, and superior.

For all outstanding performance periods, ALLETE's TSR was or will be compared to the TSR of a peer group made up of the companies in the EEI Stock Index. The ECHC Committee believes that the companies comprising the EEI Stock Index reflect comparable investment alternatives available to shareholders. The specific peer group we use consists of all the companies that were in the EEI Stock Index as of December 31 of the last year in each three-year performance period, and that have been in the EEI Stock Index for at least three full years as of that date.

------

The EEI Stock Index companies as of December 31, 2022, based on information published as of that date, were as follows:

<sup>\*</sup> Companies can be dropped from or added to the EEI Stock Index during the performance period due to mergers or other activities. If a company is dropped from the EEI Stock Index during the performance period, no information related to that company will be included in the performance calculation. A company that is newly added to the EEI Stock Index after the start of the performance period also will be excluded from the performance calculation. If a company in the EEI Stock Index at the beginning of a performance period undergoes a corporate restructuring during the performance period and the company remains in the EEI Stock Index following the transaction, the company will be included in the performance calculation. During 2019, SCANA Corporation merged with Dominion Energy, Inc., and Vectren Corporation merged with CenterPoint Energy, Inc. During 2020, El Paso Electric was dropped from the EEI Stock Index after being acquired by a private investment fund.

During the three-year performance period ending on December 31, 2022, ALLETE's shareholders realized a TSR of negative 10.3 percent, ranking us in the 2nd percentile of the peer group companies, and resulting in no PSA payout.

For the 2020-2022 performance period, EPS CAGR was measured using as a baseline ALLETE's EPS for the year ending December 31, 2019, adjusted to exclude the gain on the sale of U.S. Water Services and results from U.S. Water Services operations, and calculating ALLETE's annual EPS, with those exclusions, at the end of the three-year performance period. During the three-year performance period ending on December 31, 2022, ALLETE EPS CAGR was negative two percent, ranking us below threshold, and resulting in no PSA payout.

For the 2021-2023 performance period, EPS CAGR will be measured using as a baseline ALLETE's EPS for the year ending December 31, 2020 and calculating ALLETE's annual EPS at the end of the

three-year performance period. For the 2022-2024 performance period, EPS CAGR will be measured using as a baseline ALLETE's EPS for the year ending December 31, 2020 and calculating ALLETE's annual EPS at the end of the three-year performance period. Target was set at the midpoint of earnings guidance, or six percent, with threshold at four percent, and superior at eight percent. If the EPS CAGR percentage result at the end of the performance period is below threshold, no PSAs with the EPS CAGR performance metric will be earned. Straight-line interpolation will be used to determine earned awards based on the EPS CAGR percentage result between threshold, target, and superior.

<u>Restricted Stock Units (RSUs)</u>

RSUs are used as a retention incentive and to encourage stock ownership. One RSU entitles the NEO to receive one share of Common Stock and accrued dividend equivalents after the RSU vests at the end of a three-year period.

The table below shows 2022 LTIP target opportunities for the NEOs. For all NEOs, the target opportunities were allocated as follows: 75 percent to PSAs (half of which use relative TSR as the performance metric and half of which use EPS CAGR as the performance metric) and 25 percent to RSUs. The Company retained Willis Towers Watson to calculate the estimated fair value of PSAs. For PSAs with relative TSR as the associated performance measure, the estimated fair value reflects a modeled probability of achieving the performance goals, employing a Monte-Carlo simulation that uses an underlying Black-Scholes model. The target number of PSAs (TSR) is determined by dividing each NEO's target award opportunity—shown in the table below—by $77.61, the estimated fair value of a PSA (TSR) as of December 31, 2021. For PSAs with EPS CAGR as the associated performance metric, the valuation was calculated using a per-share value of $66.35, the closing price for Common Stock on December 31, 2021. The number of RSUs granted to the NEOs was also calculated using a per-share value of $66.35.

**OTHER GUIDELINES, POLICIES, BENEFITS, AND PRACTICES**

**Executive Share Ownership Guidelines**

We believe NEOs should be ALLETE shareholders to encourage them to act as owners and focus on long-term, sustained performance when making business decisions. We use Common Stock to fund NEOs' long-term incentive compensation and a portion of the Company's contribution to NEOs'

tax-qualified, defined-contribution retirement savings plan accounts.

Under our share ownership guidelines that have been established by the CG Committee as discussed on page 30, Ms. Owen is expected to own shares of Common Stock that have a value equal to five times her annual base salary. Mr. Morris is expected to own shares of Common Stock that have a value equal to three times his annual base salary. All other NEO are expected to own shares of Common Stock that have a value equal to their respective annual base salary.

Common Stock may be owned directly by the NEO, owned jointly with or separately by the NEO's spouse, or held in trust for the benefit of the NEO, the NEO's spouse, or the NEO's dependent children. RSUs that have been granted but not yet time-vested are counted as Common Stock under the share ownership guidelines.

The share ownership guidelines essentially require that NEOs retain 100% of any Common Stock they receive under the LTIP (after share withholding to satisfy tax obligations) until they have achieved the applicable ownership guideline.

NEOs are expected to meet their share ownership guideline within seven years after first becoming subject to the stock ownership guidelines. NEOs who are promoted to a position with a higher stock ownership expectation have five years from the promotion to meet their new guideline.

At least annually, the CG Committee reviews Common Stock ownership to confirm that the NEOs have met or are making reasonable progress toward their stock ownership guidelines.

The CG Committee may reduce the share ownership guideline for a Director or NEO following a publicly announced plan to retire or in other circumstances the CG Committee deems appropriate.

Each NEO has already met, or is making reasonable progress toward meeting, their share ownership guideline. Common Stock ownership levels as of March 10, 2023, and how ownership is measured against share ownership guidelines as of March 10, 2023, are shown in the table on page 9.

------

**Compensation Recovery Policy**

Our Compensation Recovery Policy, sometimes called a clawback policy, allows ALLETE to recover incentive payments and other forms of compensation from NEOs if any of the following events occur:

*• Financial restatement.* In the event of an accounting restatement due to material non-compliance with financial reporting rules, we can recover any excess payments made pursuant to the AIP or the LTIP in the three-year period prior to the date on which the Company is required to prepare the restatement.

*• Error*. In the event of a material error in the measurement of performance criteria, we can recover any excess payments made pursuant to the AIP or the LTIP during the three years prior to the discovery of the error.

*• Misconduct*. If an NEO engages in criminal behavior or work-related dishonesty, we can recover any AIP awards, LTIP awards, and bonuses that were paid during and subsequent to the period of misconduct.

**Shareholder Advisory Voting on Executive Compensation** 

Each year, shareholders cast an advisory vote on executive compensation, commonly known as a

"say-on-pay." At the 2022 Annual Meeting, more than 92.9 percent of the votes cast by our shareholders approved the Company's 2021 executive compensation on an advisory basis.

We believe that this say-on-pay vote affirms our executive compensation philosophy and objectives. The ECHC Committee considers the result of the say-on-pay vote as it makes its compensation decisions and the most recent shareholder advisory approval was a factor in the ECHC Committee's decision not to make any fundamental changes to ALLETE's executive compensation program.

We believe that holding an advisory shareholder say-on-pay vote on an annual basis is the appropriate frequency to promote shareholder awareness of executive compensation and to allow shareholders to provide feedback about ALLETE's executive compensation practices on a regular basis. Annual

say-on-pay voting is also consistent with ALLETE's desire to maintain effective relationships with our shareholders.

**Pledging, Hedging, and Short Sales by NEOs Prohibited**

NEOs are prohibited from holding Common Stock in a margin account or otherwise entering into any pledge arrangement that would permit a third party to sell the securities without the NEO's consent or knowledge. In addition, NEOs may not enter into any transaction that allows them to be insulated from the full risk or reward of Common Stock ownership (i.e., hedging) and NEOs may not enter into any transaction that could result in allowing them to benefit from a decrease in the value of Common Stock (e.g., short sale).

------

**Retirement and Other Broad-Based Benefits**

We provide benefits, including retirement benefits, to attract and retain executive talent. Retirement benefits also reward long-term service with the Company. NEOs are eligible for retirement benefits under the same plans available to other eligible employees. NEOs are also eligible for supplemental retirement benefits under our supplemental executive retirement plans.

NEOs participate in a range of broad-based employee benefits, including vacation pay, sick pay, disability benefits, a flexible compensation plan, an employee stock purchase plan, group term life insurance, and both active and post-retirement health benefits.

<u>Tax-Qualified Retirement Benefits</u>

For all NEOs except Ms. Thickens, who was hired after September 2006, we provide tax-qualified retirement benefits from two primary sources: (1) the RSOP, a defined-contribution retirement savings and stock ownership plan, and (2) traditional defined benefit pension plans. Since October 2006, we have emphasized delivering nonunion retirement benefits through the RSOP; therefore, for Ms. Thickens, her tax-qualified retirement benefit comes only from the RSOP. Both the RSOP and pension plan benefits are intended to be tax-qualified.

The RSOP has features of both an employee stock ownership plan and a 401(k) savings plan. NEOs may elect to defer salary into the RSOP up to the limits imposed by the Tax Code and the RSOP. In addition, we contribute to the NEOs' RSOP accounts a matching contribution of up to four percent of base salary for all NEOs, except Ms. Thickens, and up to five percent for Ms. Thickens. All NEOs, except Ms. Thickens, are also eligible for an annual Company contribution of between 8.5 percent and 11.5 percent of base salary, depending on the NEO's age. Ms. Thickens is eligible for an annual contribution of six percent. The amount contributed by the Company to each NEO under the RSOP is included in column (h) of the Summary Compensation Table on page 56.

The present value of each eligible NEO's pension benefits as of December 31, 2022, is shown in the Pension Benefits table on page 64. The 2022 increase in the pension benefits value for each eligible NEO is included in column (g) of the Summary Compensation Table on page 56.

<u>Supplemental Executive Retirement Benefits</u>

We provide supplemental retirement benefits to NEOs through the SERP, our non-tax-qualified retirement plan. Generally, the SERP is designed to provide benefits that, in the aggregate, substantially equal the benefits the NEOs would have been entitled to receive if the Tax Code did not limit the types and amounts of compensation that can be considered under tax-qualified benefit plans. Providing SERP benefits is also a recruiting and retention strategy for executive talent because it provides additional retirement planning opportunities.

The SERP has three components: a supplemental pension benefit, a supplemental defined contribution benefit, and a deferral account benefit. The SERP benefits are discussed in more detail starting on page 65.

------

**Perquisites**

The Company gives executives limited perquisites. Perquisites are tailored to the individual NEO, take into account business purpose, and may include: club memberships; reimbursement for financial and tax planning services; identity theft coverage; approved travel, meal, and entertainment expenses for spouses; and executive physicals. As required by the Tax Code, we impute income to the NEOs for reimbursement of personal expenses; we provide no tax gross-ups for this imputed income.

The ECHC Committee has reviewed all perquisites and determined that they are a minimal component of total compensation and facilitate the NEOs' performance of their job responsibilities. In 2022, each NEO received less than $10,000 in perquisites.

**Severance Benefits** 

We have no employment agreements with any of our NEOs. Under the CIC Severance Plan, NEOs could receive severance benefits in connection with a change in control of the Company. The CIC Severance Plan would provide benefits in the event of an involuntary termination of employment (or resignation following certain unfavorable changes made to an NEO's duties, compensation, or benefits) occurring within six months before, or up to two years after, a change in control. The CIC Severance Plan is designed to encourage executives to remain dedicated and objective when evaluating transactions that could result in a loss of employment in connection with a potential change in control and to minimize the risk that executives would depart prior to a change in control. The ECHC Committee believes that the most effective way to accomplish these objectives is to require both a change in control and termination of employment before severance benefits are paid. This ensures that NEOs would not receive severance benefits unless they are adversely affected by a change in control.

During 2022, the CIC Severance Plan would have provided Ms. Owen and Mr. Morris with a lump-sum severance payment equal to two and one-half times their annual cash compensation. The CIC Severance Plan would have provided Ms. Thickens, Ms. Johnson, and Mr. Cutshall with a lump-sum severance payment equal to two times their annual cash compensation. Mr. Adams' eligibility for benefits under the CIC Severance Plan ended upon his retirement in June 2022. The CIC Severance Plan also contains a modified payment cap whereby the payment would be reduced below the Tax Code Section 280G safe harbor amount if that would result in a greater after-tax amount to the NEO than the after-tax amount that would be retained if the Company paid an unreduced benefit subject to the excise tax. We provide no tax gross-up in connection with any severance payments under the CIC Severance Plan. As it does each year, the ECHC Committee reviewed the terms of the CIC Severance Plan in 2022, in consultation with Pearl Meyer, and believes that the CIC Severance Plan aligns with mainstream practice.

The SERP II includes a change in control provision that accelerates payment of the supplemental executive retirement benefits and deferral account benefits, earned after December 31, 2004, upon a termination of employment in connection with a change in control. There are also change in control features in both the AIP and the LTIP. The change in control features in the SERP II, the AIP, and the LTIP are designed to protect NEOs from losing previously-granted benefits on account of a change in control.

The potential value of the change in control severance benefits is discussed more fully in the "Potential Payments Upon Termination or Change in Control" section starting on page 69.

------

**Tax and Accounting Considerations**

We attempt to structure NEOs' compensation in a manner that maximizes the Company's ability to recognize tax deductions and we consider the accounting implications of our compensation elements. Because the primary objectives of our compensation programs are tied to performance, however, the ECHC Committee may design a compensation structure regardless of whether it qualifies for a tax deduction or more favorable accounting treatment if deemed in the Company's best interest. We do not provide tax gross-ups on payments to NEOs, except in connection with relocation expenses covered under the Company's broad-based relocation policy.

Section 280G of the Tax Code limits the amount that we may deduct for payments in connection with a change in control, commonly referred to as "parachute payments." If total payments to any covered individual in connection with a change in control exceed the Section 280G limits, the Company's deduction would be limited and the recipient's parachute payments would be subject to an excise tax. The CIC Severance Plan has a modified severance payment cap that limits payments to a level below the safe harbor amount provided by Tax Code Section 280G if the NEO would retain a greater after-tax amount than the after-tax amount that would be retained if the Company paid an unreduced benefit that was subject to the excise tax.

<sup>1</sup> The principal positions shown above are as of March 10, 2023.

<sup>2&nbsp;&nbsp;&nbsp;&nbsp;</sup>The amounts in column (d) represent discretionary cash bonuses paid in connection with the acquisition of New Energy.

<sup>3</sup> The amounts shown in column (e) represent the actuarial value of a future payout for RSUs and PSAs granted in 2022 pursuant to the LTIP and are not amounts that were paid to the NEO in the year reported. The actual amount that the NEO will earn will depend on the extent to which long-term incentive goals are achieved and on the then-current market price of Common Stock. The actual value each NEO realized in 2022 from stock awards in prior years is shown in the "Option Exercises and Stock Vested" table on page 64. The amounts in column (e) relate to RSU and PSA opportunities awarded to the NEOs during 2022. The amounts shown reflect the grant date fair value determined in accordance with generally accepted accounting principles under ASC 718, using the same assumptions used in the valuation of compensation expenses disclosed in Note 13 to the Company's Consolidated Financial Statements contained in ALLETE's Form 10-K for the year ended December 31, 2022, but based on a modeled probability of reaching performance goals and excluding the effect of estimated forfeitures. The values for 2022 and 2021 were calculated by our consultant, Willis Towers Watson; the values for 2020 were calculated by our prior consultant, Mercer. For PSAs with TSR as the performance metric, the estimated value was calculated using a Monte-Carlo simulation with an underlying Black-Scholes model. For both RSUs and PSAs with EPS CAGR as the performance metric, the estimated value was calculated using the closing price of Common Stock on February 1, 2022. The grant date fair value is the total amount that we will recognize as an expense over the awards' vesting period, except that the amounts shown do not include a reduction for forfeitures.

\* Mr. Adams retired in June 2022, resulting in accelerated vesting of the following outstanding RSU grants: 1,014 RSUs granted on January 30, 2020, 766 RSUs granted on February 2, 2021, and 229 RSUs granted on February 1, 2022. Dividend equivalent shares are also vested in connection with each grant. Mr. Adams' receipt of these shares was subject to a non-elective, six-month deferral. The value of the accelerated vesting was calculated by multiplying the exact

(non-rounded) number of shares acquired on vesting by $57.28, the closing price of Common Stock on June 17, 2022.

TSR as the performance metric will depend on actual Common Stock performance relative to the peer company group, as discussed starting on page 47, and the market price of Common Stock. The value an NEO realizes on PSAs with EPS CAGR as the performance metric will depend on the Company's baseline EPS for the year ending December 31 of the year prior to the beginning of the three-year performance period and ALLETE's earnings per share at the end of the three-year performance period, as discussed on page 47, and the market price of Common Stock. The value an NEO realizes from RSUs depends on the market value of Common Stock at the time of vesting.

**GRANTS OF PLAN-BASED AWARDS DISCUSSION**

**________________________________________________________________**

NEOs received incentive awards in 2022 consisting of AIP opportunities and LTIP opportunities, which were allocated between PSAs and RSUs.

**Annual Incentive Opportunity** 

AIP awards are discussed in detail in the Compensation Discussion and Analysis section starting on page 33. Our 2022 annual incentive goal weightings, reflected in columns (c), (d), and (e) of the Grants of Plan-Based Awards table on page 58, were as follows:

&nbsp;&nbsp;&nbsp;&nbsp;• Threshold amount shown in column (c)—the minimum AIP award, ranging from 19.8 percent to

39.6 percent of base salary as of December 31, 2022, which would be payable if net income, cash from operating activities, and strategic goals were achieved at threshold, and if there was threshold progress on operational goals and safety goals.

&nbsp;&nbsp;&nbsp;&nbsp;• Target amount shown in column (d)—the target AIP award, ranging from 45 percent to 90 percent of base salary as of December 31, 2022, which would be payable if net income, cash from operating activities, strategic goals, and operational goals and safety goals all were achieved at the target level.

&nbsp;&nbsp;&nbsp;&nbsp;• Maximum amount shown in column (e)—maximum AIP award, ranging from 90 percent to

180 percent of base salary as of December 31, 2022, which would be payable if net income, cash from operating activities, strategic goals, and operational goals and safety goals were achieved at the superior level.

Goal achievements that fall between threshold and target, and between target and superior, are interpolated on a straight-line basis.

The amounts shown in column (f) of the Summary Compensation Table on page 56 include AIP awards earned in 2022 at 104.2 percent of target for all NEOs. Annual incentive award amounts, expressed as a percentage of the NEO's salary, ranged from 33.9 percent to 93.8 percent.

NEOs may elect to receive their AIP award in cash, or to defer some or all of the awards in accordance with SERP II. An NEO who retires, dies, or becomes disabled during the year remains eligible to receive a prorated AIP award, based on actual results at the end of the year. An NEO who terminates employment for any other reason during the performance period forfeits any annual incentive award. In the event of a change in control, annual incentive awards would be calculated as if the end of the performance year had occurred, based on the Company's performance at the time of the change in control. Any awards earned would be prorated based on the number of months in the performance year which had elapsed as of the time of the change in control.

------

**PSAs**

The PSAs for the three-year performance period beginning January 1, 2022, are reflected in the Grants of Plan-Based Awards table on page 58. Beginning with the 2020-2022 performance period, PSAs are divided into two grants, each with a different performance metric. Fifty percent of the target opportunity is allocated to PSAs with relative TSR as the performance metric, as described starting on page 47; the other fifty percent of the target opportunity is allocated to PSAs with EPS CAGR as the performance metric, as described on page 48.

With respect to PSAs with TSR as the performance metric, the amounts shown in columns (f), (g), and (h) reflect the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Threshold amount shown in column (f)—the minimum 2022 PSA payable, set at 50 percent of the target opportunity, which would be earned if ALLETE's TSR percentile ranking for the

three-year performance period was at the 30th percentile among the peer group. If our TSR percentile ranking among the peer group at the end of the performance period falls below threshold, no PSAs would be paid.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Target amount shown in column (g)—the target PSA payable, which would be earned if ALLETE's TSR percentile ranking among the peer group at the end of the performance period falls at the 50th percentile.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Maximum amount shown in column (h)—the maximum PSA payable, set at 200 percent of the target opportunity, which would be earned if ALLETE's TSR percentile ranking for the three-year performance period is at the 85th percentile or higher among the peer group.

With respect to the PSAs with EPS CAGR as the performance metric, amounts shown in columns (f), (g), and (h) reflect the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Threshold amount shown in column (f)—the minimum 2022 PSA payable, set at 50 percent of the target opportunity, which would be earned if ALLETE's EPS CAGR at the end of the three-year performance period equates to a four percent average annual EPS growth rate. If our EPS CAGR result falls below threshold at the end of the performance period, no PSAs would be paid.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Target amount shown in column (g)—the target PSA payable, which would be earned if ALLETE's EPS CAGR at the end of the three-year performance period equates to a six percent average annual EPS growth rate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Maximum amount shown in column (h)—the maximum PSA payable, set at 200 percent of the target amount, which would be earned if ALLETE's EPS CAGR at the end of the three-year performance period equates to an eight percent average annual EPS growth rate.

Goal achievements that fall between threshold and target, and target and superior, are interpolated on a straight-line basis.

Dividend equivalents accrue during the performance period and allow NEOs to receive the value of dividends that would have been paid on Common Stock between the grant date and the date the performance shares are paid, but only if performance goals are achieved. If earned, performance shares and dividend equivalents are paid in Common Stock after the end of the performance period. An NEO who retires, dies, or becomes disabled during the performance period remains eligible to receive a prorated payment of performance shares. Upon a change in control, PSAs would immediately vest and be paid out on a prorated basis, including dividend equivalents, at the greater of the target level or the level earned based on the actual performance as of the date of the change in control.

------

Consistent with Financial Accounting Standards Board requirements, the grant date fair value for performance shares with the relative TSR performance metric is based on a modeled probability of reaching the performance goal. The grant date fair value for PSA with the EPS CAGR performance metric was calculated using the closing price of Common Stock on December 31, 2021. The total grant date fair value of the PSAs is included in the amount shown in column (e) of the Summary Compensation Table on page 56.

PSAs awarded for the 2021-2023 and 2022-2024 performance periods remain unearned unless and until the performance goals are achieved as measured at the end of the applicable performance period. The performance shares awarded to NEOs for those periods are shown in column (d) of the Outstanding Equity Awards at Fiscal Year-End table on page 63. The estimated market value of the unearned performance shares, assuming target TSR performance for the 2021-2023 and 2022-2024 performance periods, threshold EPS CAGR performance for the 2021-2023 performance period, and the target EPS CAGR performance for the 2022-2024 performance period is shown in column (e) of that table. The actual value to the NEOs for the performance period 2021-2023 and 2022-2024 performance periods, if any, will be determined at the end of the performance period based on the Company's actual TSR ranking and the Company's EPS CAGR results at the end of the three-year performance period.

For the 2020-2022 performance period, the Company had a relative TSR of negative 10.3 percent, which ranked in the 2<sup>nd</sup> percentile among the peer group, and an EPS CAGR of negative two percent. As a result, there was no PSA payout for the 2020-2022 performance period.

**RSUs**

The number of RSUs awarded to NEOs in 2022 is shown in column (i) of the Grants of Plan-Based Awards table on page 58. Each RSU entitles the NEO to receive one share of Common Stock when the unit vests at the end of a three-year period. The RSUs granted in 2022 will vest on December 31, 2024. The NEOs must remain employed by the Company at the time RSUs vest to receive the Common Stock. Dividend equivalents accrue during the vesting period, but are paid only if the RSUs vest. Dividend equivalents allow the NEO to receive the value of dividends that would have been paid on Common Stock during the vesting period. RSUs and dividend equivalents are paid in Common Stock after the end of the vesting period. If an NEO retires, becomes disabled, or dies, a prorated number of the RSUs would immediately vest. In the event of a change in control, restrictions in RSU grants will be deemed to have expired upon the change in control and a prorated number of the RSUs would immediately vest, unless the RSU grant is fully assumed by the successor corporation. If the RSU grant were to be fully assumed, a prorated number of RSUs would immediately vest if the NEO's employment were to be terminated by the successor corporation for reasons other than cause within 18 months of the change in control.

The full grant date fair value for RSUs awarded to each NEO is included in the amount shown in column (e) of the Summary Compensation Table on page 56. The number of unvested RSUs outstanding at the end of 2022, including dividend equivalents, is shown in column (b) of the following Outstanding Equity Awards at Fiscal Year-End table, while the value of the award as of

December 31, 2022, is shown in column (c).

RSUs are also discussed in the CD&A section on pages 47 and 49.

<sup>1&nbsp;&nbsp;&nbsp;&nbsp;</sup>The amounts in column (b) for all NEOs, except Mr. Adams, are comprised of RSUs granted on January 30, 2020, February 2, 2021, and February 1, 2022, plus dividend equivalents. The amount for Mr. Morris also includes RSUs granted on February 9, 2022 in connection with his promotion, plus dividend equivalents. RSUs vest over a three-year period provided the NEO continues to be employed by the Company. Mr. Adams' RSUs vested on June 17, 2022, upon his separation from service in connection with his retirement. The number of shares Mr. Adams received and value he realized on the vesting of his RSUs is shown in the Option Exercises and Stock Vested table on page 64.

<sup>2&nbsp;&nbsp;&nbsp;&nbsp;</sup>The amounts in column (c) were calculated by multiplying the number of units in column (b) by $64.51, the closing price of Common Stock on December 30, 2022.

<sup>3&nbsp;&nbsp;&nbsp;&nbsp;</sup>The amounts in column (d) represent the Common Stock that would become payable for outstanding PSAs if target performance were achieved for the 2021-2023 and 2022-2024 performance period for the TSR, if threshold performance were achieved for the EPS CAGR metric for the 2021-2023, and if target were achieved for the EPS CAGR metric for 2022-2024 performance period. For the PSAs based on the TSR metric, threshold performance means a TSR ranking at the 30th percentile among the peer group comprised of the EEI Stock Index companies and target means a TSR ranking at the 50th percentile among the peer group comprised of the EEI Stock Index companies as described starting on page 47. For PSAs based on the EPS CAGR metric, threshold means a four percent average annual EPS growth rate and target means a six percent average annual EPS growth rate as discussed on page 48. If the performance period had ended on December 31, 2022, PSAs for the TSR metric would have been earned for the 2021-2023 performance period at 54 percent and for the 2022-2023 performance period at 80 percent. If the performance period had ended on December 31, 2022, PSAs based on the EPS CAGR metric would not have been earned for the 2021-2023 performance period and, for the 2022-2024 period, would have been earned at 55 percent. The amount shown for Mr. Adams reflects the reduced (prorated) amount for which he remained eligible on December 31, 2022, following his separation from service on June 17, 2022 in connection with his retirement.

<sup>4</sup> &nbsp;&nbsp;&nbsp;&nbsp;The amounts in column (e) were calculated by multiplying the number of shares and units in column (d) by $64.51, the closing price of Common Stock on December 30, 2022.

<sup>1&nbsp;&nbsp;&nbsp;&nbsp;</sup>The amounts reflect the RSUs that vested at the end of the 2019-2021 vesting period, which were paid in Common Stock on February 9, 2022. All amounts shown have been rounded to the nearest whole share, whereas actual Common Stock payments included fractional shares. The amount shown for Mr. Adams also includes the following prorated amounts that vested on June 17, 2022, coincident with his separation from service in connection with his retirement: 1,014 RSUs granted on January 30, 2020, 766 RSUs granted on February 2, 2021, and 229 RSUs granted on February 1, 2022. These additional vested RSUs for Mr. Adams were not paid to him in Common Stock in 2022 because they were subject to a

non-elective, six-month delay under Tax Code Section 409A. Mr. Adams' vested but unpaid RSUs continued to earn dividend equivalents until they were paid in Common Stock in February 2023.

<sup>2&nbsp;&nbsp;&nbsp;&nbsp;</sup>The value realized on vesting, shown in column (c) is calculated by multiplying the number of shares acquired on vesting, as shown in column (b), by $63.74, the closing price of Common Stock on the February 9, 2022 payment date, except that the portion of Mr. Adams' RSUs that vested on June 17, 2022 in connection with his separation from service but were not yet paid on December 31, 2022, are valued using $57.28, the closing price of Common Stock on June 17, 2022. These RSUs were paid using $59.85, the closing price of Common Stock on February 9, 2023, and valued at $115,076.

<sup>1&nbsp;&nbsp;&nbsp;&nbsp;</sup>Ms. Thickens is not included in the table above because she is not eligible for qualified or non-qualified pension benefits having joined the Company after September 30, 2006, the date as of which pension retirement benefits under both the qualified and non-qualified plans were closed to new participants. Ms. Johnson and Mr. Cutshall are eligible to receive qualified pension benefits only, as they first became participants under SERP II after September 30, 2006, the date as of which non-qualified retirement benefits were closed to new participants.

<sup>2&nbsp;&nbsp;&nbsp;&nbsp;</sup>No service has been credited under the nonunion pension plan since September 30, 2006. The numbers in column (c) for SERP II reflect years of service with the Company through December 31, 2018.

<sup>3&nbsp;&nbsp;&nbsp;&nbsp;</sup>The amounts shown in column (d) represent the discounted net present value of the annual annuity payments to which NEOs would be entitled at retirement assuming they retire at age 62, the earliest age at which NEOs can receive unreduced pension benefits. Mr. Adams separated from service on June 17, 2022 in connection with his retirement and the amounts shown for him represent the discounted net present value of the annuity payments he became entitled to receive after that date. In addition to retirement age, the following assumptions were used to calculate the present value of accumulated benefits for all NEOs except Mr. Adams: discount rate of 5.69 percent; cost of living adjustment of 4 percent for 2023 and

2.5 percent afterwards; and female spouses are assumed to be three years younger than male spouses. For Mr. Adams, who elected to receive payments over a 15-year period commencing at retirement, a discount rate of 5.69 percent was used to calculate the present value of his accumulated benefit. The amounts for all NEOs reflect the accumulated pension benefits over the years of credited service shown for each plan.

**PENSION BENEFITS DISCUSSION**

**________________________________________________________________**

ALLETE's defined-benefit nonunion pension plan is intended to be tax-qualified and covers some of our employees, including all NEOs, except Ms. Thickens. Nonunion pension benefits are calculated based on years of service and final average earnings. As part of a company-wide nonunion benefit change, no employee accrued additional credited service for nonunion pension benefits after September 30, 2006. In 2018, additional changes were made to all participating nonunion employees' pension benefits to freeze final average earnings as of November 30, 2018. The nonunion pension benefit is calculated as a life annuity using the following formula:

---

| | | | | |
|:---|:---|:---|:---|:---|
| 0.8% | × | (years of credited service from July 1, 1980<br>through September 30, 2006) | × | final average earnings through November 30, 2018\* |

---

\* Final average earnings includes the highest consecutive 48 months of salary in the

fifteen-year period ending November 30, 2018.

Normal retirement age under the nonunion pension plan is age 65 with at least five years of continuous service with the Company. NEOs become eligible for an unreduced early-retirement benefit at age 62 if they have at least 10 years of continuous service, or at age 58 if they have at least 40 years of continuous service. NEOs are first eligible for a reduced early-retirement benefit at age 50 with at least 10 years of continuous service. Early-retirement benefits are calculated by reducing the retirement benefit by 4 percent for each year and partial year between age 62 and the early-retirement benefit commencement age. Each eligible NEO, except Ms. Johnson, is currently eligible to receive

early retirement benefits.

The normal form of benefit payment under the nonunion pension plan for a married participant is a life annuity with a 60 percent surviving spouse benefit. At normal retirement age, each optional form of benefit payment is the actuarial equivalent of the normal form of benefit payment for the nonunion pension plan. The nonunion pension plan does not provide for lump sum distributions unless the lump sum equivalent value is $10,000 or less. Once a pension benefit payment has commenced, the benefit adjusts in future years to reflect changes in cost of living, with a maximum adjustment of three percent per year.

The Tax Code limits both the annual earnings that may be considered in calculating benefits under the pension plan and the annual benefit amount that the pension plan may deliver to an NEO. The SERP plans provide supplemental pension benefits, paid out of general Company assets, to eligible NEOs in amounts generally designed to maintain total benefits at the level that would have been provided by our pension plan if those benefits were not restricted by the Tax Code.

The SERP formula is calculated as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
| 0.8% | × | (years of credited service from July 1, 1980 through December 31, 2018) | × | SERP final average earnings through December 31, 2021\* |

---

\* SERP final average earnings includes the sum of the NEO's (i) annual salary in excess of the Tax Code limits imposed on nonunion qualified retirement benefits and (ii) annual incentive awards over the highest consecutive 48-month period ending December 31, 2021. The highest consecutive 48-month period for (i) and (ii) above can be different; both, however, must fall within the last 15 years of service.

------

The present value of eligible NEO's SERP pension benefit as of December 31, 2022, is shown in the Pension Benefits table on page 64. The 2022 increase in the SERP II pension benefit value for each eligible NEO is included in column (g) of the Summary Compensation Table on page 56.

Eligible NEOs have elected a date when their SERP retirement benefit payments will commence and has elected the form of benefit payment. The normal form of payment for SERP II is a 15-year annuity. The optional forms of payment for SERP II benefits are a life annuity or a lump sum, each of which is actuarially equivalent to the normal form of payment.

SERP II benefits vest and become payable only if the NEO (i) retires after reaching age 50 with 10 years of service, (ii) becomes disabled after reaching age 50 with 10 years of service, or (iii) reaches age 50 after becoming disabled with 10 years of service. Vested SERP II benefit payments commence upon the earlier of retirement or disability, or, if a disability occurs prior to vesting, the earlier of attaining age 65 or the date of death. Payment of the SERP II benefits accrued after December 31, 2004 would be accelerated and paid as a lump sum upon a termination of employment in connection with a change in control.

In all other respects, the eligibility requirements for SERP retirement benefits and the calculation of SERP early retirement benefits are the same as the nonunion pension plan's eligibility requirements and early retirement benefits discussed above.

On December 31, 2004, the Company froze SERP I with respect to all plan benefits. Effective

January 1, 2005, the Company established SERP II to comply with Section 409A of the Tax Code. SERP II covers compensation initially deferred, and supplemental pension and supplemental defined contribution benefits accrued or vested, after December 31, 2004.

Effective October 1, 2006, the Company froze eligibility for supplemental pension benefits under

SERP II. Individuals who were not SERP II participants and eligible for supplemental pension benefits on September 30, 2006, are not eligible for supplemental pension benefits.

Supplemental executive retirement benefits were reviewed in 2018 in light of Company cost competitiveness and benchmarking data. Credited service for calculating the supplemental pension benefits was frozen as of December 31, 2018. In addition, amounts NEOs defer to their SERP II deferral account after December 31, 2018, will no longer receive a fixed annual interest crediting rate and will instead be credited or debited with notional gains or losses until the balance has been paid in full. In response to changes in the tax law discussed on page 52, SERP II was also amended in 2018, effective January 1, 2019, to eliminate the provision that required a non-elective deferral of the portion of a participant's AIP that the Company could not deduct by application of Section 162(m) of the

Tax Code. SERP II was further amended in 2021 to freeze final average earnings as of

December 31, 2021.

As of December 31, 2022, all NEOs, except Ms. Thickens, Ms. Johnson, and Mr. Cutshall, have vested SERP supplemental pension benefits. Because Ms. Thickens, Ms. Johnson, and Mr. Cutshall were not eligible to participate in SERP II before September 30, 2006, they are not eligible for supplemental SERP pension benefits.

------

ALLETE provides a supplemental defined contribution benefit and a deferral account benefit to the NEOs. The SERP II supplemental defined contribution benefit provides a benefit that is substantially equal to the benefit the NEO would have been entitled to receive if the Tax Code did not impose limitations on the types and amounts of compensation that can be included in the benefit calculations under the ALLETE and Affiliated Companies Flexible Compensation Plan and the RSOP. Annually, NEOs may elect to defer some or all of their salary and annual incentive award to a SERP II deferral account. NEOs whose base salary is below the tax-qualified benefit plans' annual compensation limit may also elect to defer some or all of the SERP II defined contribution benefit. NEOs can select among different crediting rates to apply to deferral balances under the SERP Plans and the investment options generally match the investment options available to all employees under the RSOP. These investment options include mutual funds and similar investments. The NEOs may change their investment elections at any time. The amount of the 2022 SERP II defined contribution benefit received by each NEO is included in column (h) of the Summary Compensation Table on page 56. The aggregate amount each NEO elected to defer and the amount that the Company contributed to the SERP II in 2022 are shown in the Non-Qualified Deferred Compensation table on page 68.

Each NEO has elected a date when benefit payments from the NEO's SERP I and SERP II deferral accounts will commence and has elected the form of benefit payment. SERP I and SERP II deferral account benefit payments will not begin earlier than the elected commencement date. NEOs may request an early distribution of some or all of their SERP I deferral account balance upon a demonstrated severe financial need or, at any time prior to the elected commencement date, may elect an early withdrawal of contributions made to their account prior to January 1, 2005, subject to a ten percent early withdrawal penalty.

NEOs may not elect to receive an early withdrawal of amounts contributed to their SERP II deferral accounts after December 31, 2004, except that they may request early withdrawal in the event of an unforeseen emergency, which request is subject to the approval of the ECHC Committee. Contributions made to a SERP II deferral account after December 31, 2004, would be paid in full upon a termination of the NEO's employment in connection with a change in control.

NEOs may elect to receive their SERP deferral account balance in the form of either a lump sum or monthly installments over a 5-, 10-, or 15-year period, or a combination of lump sum payment and monthly installments.

NEOs' SERP balances for deferrals made on or before December 31, 2018, will receive a fixed

7.5 percent annual interest crediting rate until paid in full; SERP II balances for deferrals made on or after January 1, 2019, will be will be credited or debited with notional gains or losses until the balance has been paid in full.

The portion of his SERP II deferral account for which he elected to receive monthly distributions over a 15-year period commencing at retirement was withdrawn from his SERP II account at his retirement but distributions did not commence until January 2023, after the expiration of a non-elective, six-month delay imposed by Tax Code Section 409A. The remaining portion of Mr. Adams' SERP II deferral account, which was comprised of deferrals made on or after January 1, 2019, was not withdrawn from his account and continued to be credited and debited with notional gains or losses until it was distributed as a lump-sum payment, in accordance with his election, in January 2023, after the expiration of the non-elective, six-month delay imposed by Tax Code Section 409A.

**POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL**

**________________________________________________________________**

The NEOs are covered by the CIC Severance Plan. Under the CIC Severance Plan, a change in control generally means any one of the following events:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Acquisition of more than 50 percent of the total fair market value or total voting power of Common Stock by any person, entity, or group acting together;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Acquisition in any 12-month period of 40 percent or more of the Company's assets by any person, entity, or group acting together;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Acquisition in any 12-month period of 30 percent or more of the total voting power of Common Stock by any person, entity, or group acting together; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A majority of members of the Board is replaced during any 12-month period by Directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of appointment or election.

Each NEO is entitled to receive specified benefits in the event the NEO's employment is involuntarily terminated during the period beginning six months before and ending two years after a change in control. An involuntary termination is deemed to occur if (i) the Company terminates the employment of the NEO other than for cause, or (ii) the NEO resigns from their employment with good reason. Cause generally includes reasons such as failure to perform duties, willful misconduct, or felony convictions. Good reason generally means a material reduction in the NEO's responsibilities or authority; a material reduction in their supervisory responsibilities or authority; a material reduction in base salary, incentive compensation, or other benefits; a material breach by the Company of an agreement under which an NEO provides services; or reassignment to another geographic location more than 50 miles from the NEO's current job location.

Under the CIC Severance Plan, if a triggering event had occurred on December 31, 2022, Ms. Owen and Mr. Morris would have been entitled to receive a lump-sum severance payment equal to two and one-half times their annual compensation as of December 31, 2022. Ms. Thickens, Ms. Johnson, and Mr. Cutshall would be entitled to a payment equal to two times their annual compensation as of December 31, 2022. Mr. Adams, who retired as of June 30, 2022, was not eligible for benefits under the CIC Severance Plan on December 31, 2022. Annual compensation includes base salary and an amount representing a target award under the annual incentive in effect for the year of termination. The CIC Severance Plan has a modified severance payment cap that limits payments to a level below the safe harbor amount provided by Tax Code Section 280G if the NEO would retain a greater after-tax amount than the after-tax amount that would be retained if the Company paid an unreduced benefit that was subject to the excise tax.

The AIP and LTIP also have change in control features. Under the AIP, in the event of a change in control (as defined in the AIP), any award earned based on actual results as of the date of the change in control will be prorated based on the number of months in the performance year elapsed as of the date of the change in control. Under the LTIP, in the event of a change in control (as defined in the LTIP), restrictions in RSU grants would be deemed to have expired upon the change in control and a prorated number of the RSUs would immediately vest, unless the RSU grants were fully assumed by the successor corporation. If the RSU grants were fully assumed, a prorated number of RSUs would immediately vest if the NEO's employment was terminated by the successor corporation for reasons other than cause within 18 months of the change in control. If a change in control were to occur, PSAs would immediately pay out on a prorated basis at the greater of target level or the level earned, based on then-current TSR ranking and then-current EPS CAGR results.

------

As a condition of receiving payments under the CIC Severance Plan, participants must sign a waiver of potential claims against the Company and must agree not to disclose confidential information, engage in any business in competition with the Company for a period of one year, recruit any employee or Director of the Company for employment for a period of two years, or publicly disparage the Company.

**Estimated Potential Payments Upon Termination Associated with a Change in Control**

The table below illustrates the value that would have been received by NEOs if a change in control had occurred on December 31, 2022, and if, as a result, the NEO's employment had been terminated on the same date. Mr. Adams is not included in the table because of his June 30, 2022 retirement.

<sup>1&nbsp;&nbsp;&nbsp;&nbsp;</sup>The values for severance payments were calculated based on December 31, 2022, base salary, target annual incentive, and the applicable severance benefit multiple of salary. Under the CIC Severance Plan, if payments constitute "excess parachute payments" within the meaning of Tax Code Section 280G, the payments would be reduced only if the NEO would receive a greater net after-tax benefit than they otherwise would receive with no reduction in payments. The amounts shown above reflect no such reductions.

<sup>2&nbsp;&nbsp;&nbsp;&nbsp;</sup>The performance period ended on December 31, 2022. Therefore, no benefit acceleration would have occurred under this scenario.

<sup>3</sup> Outstanding performance shares for the 2020-2022, 2021-2023, and 2022-2024 performance periods would accelerate under this scenario. Under the LTIP, if a change in control and employment termination were to occur, performance shares would be paid on a prorated basis based on the number of months that had transpired as of December 31, 2022 for each applicable three-year performance period and using the greater of actual performance or target as of December 31, 2022. The award values shown reflect the proration, were calculated at target for each performance period, and reflect the $64.51 closing price of Common Stock on December 30, 2022.

<sup>4&nbsp;&nbsp;&nbsp;&nbsp;</sup>Under the LTIP, if a change in control and employment termination were to occur, unvested RSUs would vest and be payable on a prorated basis based on the number of months that had transpired between the start of the three-year vesting period and December 31, 2022 relative to the full three-year vesting period.

<sup>5&nbsp;&nbsp;&nbsp;&nbsp;</sup>The CIC Severance Plan does not provide for any additional age or service credit for supplemental executive retirement benefits under the SERP.

<sup>6&nbsp;&nbsp;&nbsp;&nbsp;</sup>The values for benefit payments were based on the applicable severance multiplier times the sum of (i) medical, dental, and basic group term life insurance benefit premiums, and (ii) Company contributions under the Flexible Compensation Plan.

<sup>7&nbsp;&nbsp;&nbsp;&nbsp;</sup>The Company will pay outplacement directly to service providers up to the amount shown for the cost of outplacement services provided to the NEOs. No amount will be paid unless the NEO utilizes outplacement services within the time frame specified in the CIC Severance Plan.

<sup>8 &nbsp;&nbsp;&nbsp;&nbsp;</sup>The CIC Severance Plan provides that if payments are delayed as a result of Tax Code Section 409A, interest is required to be paid at the short-term applicable federal rate. The amounts shown exclude interest.

------

**Estimated Potential Payments Upon Termination Due to Retirement, Disability, or Death**

If NEOs were to retire, become disabled, or die, they would become entitled to receive prorated PSAs if PSA goals are achieved at the conclusion of the applicable three-year performance period. The LTIP also provides for immediate, accelerated vesting of RSUs, on a prorated basis, upon an NEO's retirement, disability, or death. The following table illustrates the value NEOs would have received in connection with accelerated vesting and payments triggered by a retirement, disability, or death had the event occurred on December 31, 2022.The amount shown for Mr. Adams reflects what he received, or is eligible to receive, in connection with his retirement as of June 30, 2022.

<sup>1&nbsp;&nbsp;&nbsp;&nbsp;</sup>Because the annual performance period ended on December 31, 2022, no acceleration of benefits would have occurred.

<sup>2&nbsp;&nbsp;&nbsp;&nbsp;</sup>Outstanding performance shares for the performance periods 2020-2022, 2021-2023, and 2022-2024 would be earned on a prorated basis under this scenario if TSR and EPS CAGR performance goals were achieved at the conclusion of each

three-year performance period. The award values show assume PSA for the TSR metric would have been earned for the 2021-2023 performance period at 54 percent and for the 2022-2023 performance period at 80 percent and PSAs based on the EPS CAGR metric would not have been earned for the 2021-2023 performance period and, for the 2022-2024 period, would have been earned at 55 percent. No amount is included for the 2020-2022 performance period based on actual performance through December 31, 2022. For all NEOs except Mr. Adams, award values were calculated using $64.51, the closing price of Common Stock on December 30, 2022. For Mr. Adams, award values were calculated using $57.28, the closing share price on June 17, 2022, the date he separated from service in connection with his retirement; also in connection with his retirement, the amount shown for Mr. Adams reflects an 18/36 proration of his grant for the 2021-2023 performance period and a 6/36 proration of his grant for the 2022-2024 performance period.

<sup>3&nbsp;&nbsp;&nbsp;&nbsp;</sup>For all NEOs except Mr. Adams, the values shown reflect the $64.51 closing price of Common Stock on December 30, 2022. Mr. Adams' outstanding RSUs vested on a pro rata basis based on his retirement in June 2022. Mr. Adams' grant for the 2020-2022 performance period was prorated at 30/36, his grant for the 2021-2023 performance period was prorated at 18/36, and his grant for the 2022-2024 performance period was prorated at 6/36. Mr. Adams' award values were calculated using $57.28, the closing share price on June 17, 2022.

**CEO PAY RATIO**

**________________________________________________________________**

Employees drive ALLETE's success. Our compensation strategy is designed to compensate all employees appropriately and competitively. When determining employee compensation, we consider multiple factors including market data, job responsibilities, experience, performance, and internal equity.

In keeping with the requirement to identify our median employee at least once every three years, we identified a new median employee in 2022. ALLETE's median employee was identified for 2022 by computing the median annual W-2 Medicare reported wages for all employees who were employed on December 16, 2022, which was the last day of ALLETE's 2022 payroll reporting period, other than the CEO and 80 employees who became employees as the result of ALLETE's acquisition of New Energy in 2022. We did not make assumptions, adjustments, or estimates; nor did we annualize compensation for any full-time employee who was not employed for all of 2022.

We calculated the median employee's 2022 annual total compensation using the same methodology used to report the NEO's compensation in the Summary Compensation Table on page 56. The total compensation reported in column (i) of the Summary Compensation Table for Ms. Owen in 2022 is $2,338,422. This amount is 21 times that of the median employee's 2022 total compensation of $111,305.

We believe the pay ratio disclosed above is a reasonable estimate calculated in accordance with SEC rules, based on our records and the methodology described above. The SEC rules for identifying the median employee and calculating the pay ratio based on that employee's annual total compensation allow companies to use a variety of methodologies, to apply various assumptions, and to make reasonable estimates and exclusions. The application of various methodologies, assumptions, estimates, and exclusions may result in significant differences in the results reported by SEC reporting companies. For this reason, the CEO pay ratio reported by other companies may not be comparable to the pay ratio reported above.

------

**PAY VERSUS PERFORMANCE**

**________________________________________________________________**

In accordance with rules adopted by the SEC pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the following disclosure is provided regarding "compensation actually paid" for (i) ALLETE's CEO ("PEO") and (ii) ALLETE's NEOs other than the PEO on an average basis, as well as certain Company performance measures for the past three fiscal years. Ms. Owen served as PEO during 2022 and 2021, and also during the period from February 3, 2020 through

December 31, 2020. Alan R. Hodnik served as PEO from January 1, 2020 to February 2, 2020.

Refer to our CD&A starting on page 33 for a complete description of how executive compensation relates to Company performance and how the ECHC Committee makes its compensation decisions.

**DIRECTOR COMPENSATION**

**________________________________________________________________**

The ECHC Committee has primary responsibility for developing and evaluating the non-employee Director compensation program, which is then approved by the Board. The ECHC Committee reviews non-employee Director compensation annually. The ECHC Committee receives advice from its independent compensation consultant, Pearl Meyer, to help ensure that non-employee Director compensation is market-based, aligned with shareholder interests, and consistent with our compensation principles. Pearl Meyer reviews each director compensation element and total director compensation, comparing those to the director compensation of the same group of peer companies used in connection with designing ALLETE's executive compensation. See "Process for Determining Executive Compensation," page 41, for the list of the peer group companies. Pearl Meyer also examines director compensation data from similarly-sized companies in all industries. The ECHC Committee reviews Pearl Meyer's benchmarking report and determines whether to recommend to the Board any changes to non-employee Director compensation.

Based on its review and evaluation in October 2021, the ECHC Committee determined that compensation for non-employee Directors was below the market median. To align compensation more closely to the market median, effective January 1, 2022, the Board approved a 4.8% increase to the stock retainer ($97,500 compared to $93,000 in 2021) and a 6.6% increase to the cash retainer ($80,000 compared to $75,000 in 2021) for non-employee Directors.

The following table sets forth the non-employee Director compensation earned in 2022:

<sup>1 &nbsp;&nbsp;&nbsp;&nbsp;</sup>Ms. Owen is not included in this table because she was an NEO and her compensation is fully discussed in the CD&A starting on page 33 and reflected in the Summary Compensation Table on page 56.

<sup>2&nbsp;&nbsp;&nbsp;&nbsp;</sup>Mr. Goldfarb, Ms. Nestegard, Mr. Neve, and Mr. Powers elected to defer their 2022 stock retainer; Mr. Goldfarb, and

Mr. Neve elected to defer their 2022 cash retainers. Mr. Matthews elected to defer all eligible portions of his stock and cash retainers. These amounts were deferred under the Deferral Plan II.

<sup>3&nbsp;&nbsp;&nbsp;&nbsp;</sup>For all Directors except Mr. Matthews, the amounts shown in column (c) reflect the grant date fair value of the annual stock retainer paid on June 1, 2022. On that date, Directors each received 1,585.366 shares of Common Stock valued based on a share price of $61.50 (the five-day average closing price, including the date that is ten calendar days prior to June 1, 2022). Mr. Matthews received a prorated stock retainer in connection with his election to the Board on July 6, 2022. Mr. Matthews received 1,481.681 shares of Common Stock, on August 9, 2022, the calculation of which was based on a share price of $60.32 (the five-day average closing price, including the date that is ten calendar days prior to August 9, 2022).

<sup>4</sup>&nbsp;&nbsp;&nbsp;&nbsp;Ms. Dindo and Ms. Jimmerson each retired following the 2022 Annual Meeting on May 10, 2022. The amounts shown for Ms. Dindo and Ms. Jimmerson reflect the prorated cash retainers they received for their service as Directors through their May 10, 2022 retirement date. Director stock retainers are paid in advance in June of each year; for that reason, neither Ms. Dindo nor Ms. Jimmerson received a stock retainer in June 2022.

<sup>5&nbsp;&nbsp;&nbsp;&nbsp;</sup>Mr. Matthews joined the Board on July 6, 2022.

<sup>6</sup>&nbsp;&nbsp;&nbsp;&nbsp;Ms. Nestegard served as Lead Director for all of 2022.

------

Employee Directors receive no additional compensation for their services as Directors. Ms. Owen received no additional compensation in 2022 for her service on the Board and her 2022 compensation is covered in detail in the CD&A starting on page 33.

Under the terms of the ALLETE Director Stock Plan, ALLETE pays each non-employee Director an annual retainer fee, a portion of which is paid in cash and a portion of which is paid in Common Stock as set forth below:

---

| | | |
|:---|:---|:---|
| **Non-Employee Director Retainers—2022** | **Non-Employee Director Retainers—2022** | **Non-Employee Director Retainers—2022** |
|  | Cash | Stock |
| All Directors | $80000 | $97500 |
| Lead Director (Additional) | $40000 |  |

---

We also pay each non-employee Director, other than the Lead Director, an annual cash retainer for each committee membership and committee chair assignment as set forth below:

---

| | | |
|:---|:---|:---|
| **Non-Employee Committee Retainers—2022** | **Non-Employee Committee Retainers—2022** | **Non-Employee Committee Retainers—2022** |
|  | Member | Additional Chair Retainer |
| Audit Committee | $9000 | $10000 |
| Executive Compensation and Human Capital Committee | $7500 | $7500 |
| Corporate Governance and Nominating Committee | $7500 | $5000 |

---

The Lead Director receives her designated cash retainer and the Director stock retainer, but does not receive any other committee or chair retainers.

Director and committee retainers are prorated based on the actual term of service per year.

Directors may elect to receive all or part of the cash portions of their retainer fees in Common Stock.

The Company provides a deferral account benefit to the Directors under the terms of the Deferral Plans. On December 31, 2004, the Company froze Deferral Plan I with respect to all deferrals. Effective

January 1, 2005, the Company established Deferral Plan II to comply with Section 409A of the Tax Code. Deferral Plan II governs all cash retainers initially deferred after December 31, 2004. On

May 1, 2009, the Board amended Deferral Plan II to permit Directors to elect to defer their stock retainers.

Annually, non-employee Directors may elect to defer to a Deferral Plan II cash account some or all of their cash retainer fees. Directors can select among different investment crediting rates to apply to deferral cash account balances under the Deferral Plans. These investment options include mutual funds and similar investments. The Directors may change their investment elections at any time.

------

Annually, non-employee Directors also may elect to defer to a Deferral Plan II stock account some or all of their stock retainer fees. Deferred stock retainer fees are credited to a Director's stock account, which has a single investment option that mirrors the performance of our Common Stock and is credited with dividend equivalents equal to cash dividends that are declared and paid on our Common Stock.

Directors elect a date when benefit payments from their Deferral Plan I and Deferral Plan II accounts will commence and the form of benefit payment. Generally, Deferral Plan I and Deferral Plan II account benefit payments will not begin earlier than the elected commencement date. Directors may, however, request an early distribution of some or all contributions made to their Deferral Plan I account prior to January 1, 2005, subject to a 10 percent early withdrawal penalty.

Directors may not elect to receive an early withdrawal of amounts contributed to their Deferral Plan II account after January 1, 2005, except that they may request an early withdrawal in the event of an unforeseen emergency, which request is subject to the approval of the ECHC Committee.

Directors may elect to receive their Deferral Plan cash and stock account balances in the form of either a lump sum payment or annual installments over a 5-, 10-, or 15-year period, or a combination of both. A Director's Deferral Plan cash account balance will be credited or debited with notional gains or losses until the balance has been paid in full. Directors will receive dividend equivalents on their Deferral

Plan II stock account balances until paid in full.

------

**ITEM NO. 3—ADVISORY VOTE ON THE FREQUENCY OF FUTURE ADVISORY VOTES ON EXECUTIVE COMPENSATION**

**________________________________________________________________**

We have conducted annual advisory shareholder votes to approve executive compensation–like the one in Item No. 2 of this proxy statement–since the 2011 Annual Meeting. In accordance with the requirements of Section 14A of the Exchange Act and the related SEC rules, we are asking you to vote, on an advisory basis, whether future advisory votes on executive compensation should occur every year, every two years, or every three years.

Our shareholders voted on a similar proposal in 2017 with the majority voting to hold the advisory

say-on-pay vote every year. Our executive compensation programs have been designed to promote a long-term connection between executive compensation and performance. At the same time, the

ECHC Committee and the Board recognize that compensation disclosures are made annually, and we believe that annual say-on-pay voting helps to promote awareness of our executive compensation programs and provides us with the most direct and timely feedback about those programs from shareholders. We believe that holding an annual say-on-pay vote is consistent with our compensation philosophy and programs, and is also consistent with our practice of engaging shareholders and seeking their input on corporate governance matters.

Although this shareholder vote on the frequency of future advisory shareholder say-on-pay votes is advisory and non-binding, the ECHC Committee and the Board expect to take into account the outcome of the vote when considering the frequency of future advisory shareholder say-on-pay votes.

For this Item No. 3, you are not voting to approve or disapprove the Board's recommendation. Rather, you will be able to specify your preference for one of three possible frequencies, within the following four possible voting options: "one year," "two years," "three years," or "abstain."

**The Board recommends a vote for a "ONE YEAR" frequency for future advisory votes to approve executive compensation.**

------

**ITEM NO. 4—RATIFICATION OF THE SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

**________________________________________________________________**

The Audit Committee has selected PricewaterhouseCoopers as the Company's independent registered public accounting firm for the year 2023. PricewaterhouseCoopers has acted in this capacity since October 1963.

While the Audit Committee is responsible for the selection, retention, evaluation of independence and performance, approval of fees and retention terms, oversight, and termination (when appropriate) of the Company's principal independent accountants, the Audit Committee and Board request that shareholders ratify the selection of PricewaterhouseCoopers as the Company's independent registered public accounting firm as a matter of good corporate practice. The Audit Committee is not required to take any action as a result of the outcome of this vote, but will take it into consideration. Even if the selection is ratified by shareholders, the Audit Committee in its discretion may select a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and its shareholders.

A representative of PricewaterhouseCoopers is expected to be present at the 2023 Annual Meeting. The representative will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

**The Board recommends a vote "FOR" ratifying the selection of PricewaterhouseCoopers as the Company's independent registered public accounting firm for 2023.**

------

**AUDIT COMMITTEE REPORT**

**________________________________________________________________**

The Audit Committee is comprised of six non-employee Directors, each of whom has been determined by the Board to be "independent" under ALLETE's Corporate Governance Guidelines, and within the meaning of the rules of both the NYSE and the SEC. The Board has also determined that each member of the Audit Committee is financially literate and that Mr. Goldfarb, Mr. Matthews, and Mr. Neve are each an "audit committee financial expert" within the meaning of the SEC rules. The Audit Committee operates pursuant to a written charter. The Audit Committee charter was reviewed in February 2023 and revised in February 2022 and is available on the Company's website <u>www.allete.com/Governance</u>. The Audit Committee assists in the Board's oversight of the integrity of the Company's financial reports, compliance with legal and regulatory requirements, the qualifications and independence of the independent registered public accounting firm, both the internal and external audit processes, and internal controls over financial reporting. The Audit Committee reviews and recommends to the Board that the audited financial statements be included in the Company's annual Form 10-K.

During 2022, the Audit Committee met and held separate discussions with members of management and the Company's independent registered public accounting firm, PricewaterhouseCoopers, regarding certain audit activities and with the Company's Chief Audit Officer regarding the plans for and results of selected internal audits. The Audit Committee reviewed the quarterly financial statements. It reviewed with management and the independent registered public accounting firm the effectiveness of internal controls over financial reporting and the Company's compliance with laws and regulations.

The Audit Committee received and reviewed the written disclosures and letters from PricewaterhouseCoopers specified by applicable requirements of the Public Company Accounting Oversight Board (PCAOB) regarding the independent registered public accounting firm's communications with the Audit Committee concerning independence and discussed the firm's independence with the independent registered public accounting firm. The Audit Committee has received written material addressing PricewaterhouseCoopers' internal quality control procedures and other matters, as required by the NYSE listing standards.

The Audit Committee has: (i) reviewed and discussed the Company's Consolidated Financial Statements for the year ended December 31, 2022, with the Company's management and with the Company's independent registered public accounting firm; (ii) met with management to discuss all quarterly and annual financial reports prior to their issuance and to discuss significant accounting issues and management judgments; and (iii) discussed with the Company's independent registered public accounting firm the matters required to be discussed under the rules adopted by the PCAOB. Management represented to the Audit Committee that the Company's Consolidated Financial Statements were prepared in accordance with accounting principles generally accepted in the United States of America.

Based on the above-mentioned review and discussions, the Audit Committee recommended to the Board that the audited financial statements be included in ALLETE's Form 10-K for the year ended December 31, 2022.

------

**Audit Committee Pre-Approval Policies and Procedures**

The Audit Committee has pre-approval policies and procedures related to the provision of audit and non-audit services by the independent registered public accounting firm. Under these procedures, the Audit Committee pre-approves both the type of services to be provided by the independent registered public accounting firm and the estimated fees related to these services. During the pre-approval process, the Audit Committee considers the impact of the types of services and the related fees on the independence of the independent registered public accounting firm. The services and fees must be deemed compatible with the maintenance of the independence of the independent registered public accounting firm, including compliance with the SEC's rules and regulations.

The Audit Committee will, as necessary, consider and, if appropriate, pre-approve the provision of additional audit and non-audit services by the independent registered public accounting firm that were not encompassed by the Audit Committee's annual pre-approval and that are not prohibited by law. The Audit Committee has delegated to the Chair of the Audit Committee the authority to pre-approve, on a case-by-case basis, these additional audit and non-audit services, provided that the Chair shall promptly report any decisions to pre-approve such services to the Audit Committee.

**Audit and Non-Audit Fees**

The following table presents fees for professional audit services rendered by PricewaterhouseCoopers for the audit of the Company's annual financial statements for the years ended December 31, 2022 and December 31, 2021, and fees billed for other services rendered by PricewaterhouseCoopers during those periods. All audit and non-audit services and fees for 2022 and 2021 were pre-approved by the Audit Committee. The Company has considered and determined that the provision of the non-audit services noted below is compatible with maintaining PricewaterhouseCoopers' independence.

<sup>1&nbsp;&nbsp;&nbsp;&nbsp;</sup>Audit fees were incurred in connection with audit work performed on the integrated audit of the Consolidated Financial Statements, as well as work generally only the independent registered public accounting firm can reasonably be expected to provide, such as required regulatory audits, subsidiary audits, accounting consultations, and services in connection with securities offerings. 2022 audit fees also included incremental services related to the Company's acquisition of New Energy in 2022.

<sup>2</sup>&nbsp;&nbsp;&nbsp;&nbsp;Audit-related fees consisted of consultation services related to a new system implementation.

<sup>3&nbsp;&nbsp;&nbsp;&nbsp;</sup>Tax fees consisted of tax compliance services.

**OTHER BUSINESS ________________________________________________________________**

The Board knows of no other business to be presented at the 2023 Annual Meeting. However, if any other matters properly come before the Annual Meeting, it is the intention of the persons named in the proxy form to vote the Common Stock represented thereby pursuant to the proxies in accordance with their judgment in such matters.

All shareholders are respectfully asked to vote their proxies so that the necessary vote may be present at the Annual Meeting.

------

**Shareholder Proposals for the 2024 Annual Meeting**

All proposals from shareholders to be considered for inclusion in the Proxy Statement relating to the Annual Meeting scheduled for May 14, 2024, must be received by the Corporate Secretary of ALLETE at

30 West Superior Street, Duluth, MN 55802-2093 not later than November 24, 2023. The Company's Bylaws provide that for business to be properly brought before an annual meeting by a shareholder, the shareholder must have delivered timely notice to the Company's Corporate Secretary. To be timely, advance notice for business to be brought before an Annual Meeting generally must be received not less than 90 days nor more than 120 days prior to the anniversary of the immediately preceding Annual Meeting.
