2024 Management Information Circular 5 Letter to shareholders April 18, 2024 Dear fellow shareholder, I am pleased to invite you to participate in the annual meeting of common shareholders of Algonquin Power & Utilities Corp. to be held on Tuesday, June 4, 2024. The meeting will provide an opportunity to ask questions of Algonquin’s management and board of directors. Shareholders will also be voting on a number of matters. Please read the Notice of Meeting and Management Information Circular in advance, as they provide information on the meeting agenda and items of business, including the nominees for election to the board, and several other topics pertinent to the discussion. You are encouraged to participate and to exercise your vote, either during the meeting or by completing and sending in your proxy or voting instruction form prior to the meeting. Board renewal helps to reinvigorate the board with new ideas and perspectives and is a key factor in maintaining strong corporate governance and oversight of Algonquin’s business. This year, Masheed Saidi decided to retire from the board after 10 years of dedicated service. We thank Masheed for her important contributions, including in her current role as Chair of the Risk Committee. I have also decided to retire from the board this year. It has been an honour and a privilege to serve as the Chair of Algonquin’s board of directors, but just as Algonquin is in the midst of a strategic and business transition, I believe now is the appropriate time for a transition of board leadership. With the high caliber of director nominees described in the Management Information Circular, I am certain that Algonquin’s business will remain in capable hands. I would also like to welcome three new director nominees who are standing for election by shareholders for the first time. David Levenson was appointed to the board on February 1, 2024. David spent almost two decades as a Managing Partner and the Chief Investment Officer of Brookfield Asset Management, Inc. and brings extensive capital markets and corporate transactions experience to the board. Brett Carter and Chris Lopez are being nominated pursuant to the co-operation agreement between Algonquin and Starboard Value LP, Algonquin’s largest shareholder, that was announced on April 18, 2024. Brett was appointed to the board concurrently with the execution of the co-operation agreement. He has held several senior roles at Xcel Energy Inc., Bank of America Corporation, and Duke Energy Corporation focused on customer relations, operations, innovation, and technology. Chris is currently Executive Vice President, Chief Financial and Regulatory Officer at Hydro One Limited and previously held other senior roles at Hydro One and TransAlta Corporation in the finance, corporate planning, and M&A groups. I am confident that Algonquin will benefit from David, Brett, and Chris’s experience and contributions. After the formal business of the meeting, the management team will share information on Algonquin’s business and outlook. We look forward to providing updates on our key strategic and business initiatives and the decisive actions we are taking to deliver value to shareholders. For information concerning Algonquin’s consolidated financial and operational performance for the year ended December 31, 2023, consult our 2023 Annual Report, which can be found on our website (www.algonquinpower.com) or on SEDAR+ (www.sedarplus.ca). The board and management team thank you for your continued support and engagement. Yours sincerely, Kenneth Moore Chair of the Board of Directors

ALGONQUIN | LIBERTY 6 Caution concerning non-GAAP financial measures The financial statements of Algonquin Power & Utilities Corp. (the “Corporation”), including the audited consolidated financial statements for the year ended December 31, 2023 which will be presented at the annual meeting of common shareholders on June 4, 2024, are prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). Certain financial terms used in this Management Information Circular do not have standardized meanings under U.S. GAAP. These non-GAAP measures include non-GAAP financial measures and non-GAAP ratios, each as defined in Canadian National Instrument 52-112-Non-GAAP and Other Financial Measures Disclosure. The Corporation’s method of calculating these measures may differ from methods used by other companies and therefore may not be comparable to similar measures presented by other companies. The term “Adjusted Net Earnings” is a non-GAAP financial measure that is used to assess the Corporation’s performance. Adjusted Net Earnings per share (“Adjusted EPS”) is a non-GAAP ratio and is calculated by dividing Adjusted Net Earnings by the weighted average number of common shares outstanding during the applicable period. Adjusted EPS is used to assess the Corporation’s performance under the Corporate Scorecard (see page 58). Adjusted Earnings Before Interest and Taxes (“Adjusted EBIT”) is a non-GAAP financial measure that is also used to assess the Corporation’s performance under the Corporate Scorecard (see page 58). An explanation of these non-GAAP financial measures is set out below. Adjusted EBIT Adjusted EBIT is a non-GAAP financial measure used by many investors to compare companies on the basis of ability to generate income from operations. The Corporation uses Adjusted EBIT to assess the operating performance of the Corporation without the effects of (as applicable): income tax expense or recoveries, acquisition and transition costs (including costs related to the 2023 strategic review of the Corporation’s renewable energy business), certain litigation expenses, interest expense, gain or loss on derivative financial instruments, write down of intangibles and property, plant, and equipment, earnings attributable to non-controlling interests exclusive of Hypothetical Liquidation at Book Value (“HLBV”) income (which represents the value of net tax attributes earned in the period from electricity generated by certain of its U.S. wind power and U.S. solar generation facilities), non-service pension and post-employment costs, costs related to tax equity financing, costs related to management succession and executive retirement, costs related to prior period adjustments due to changes in tax law, costs related to condemnation proceedings, gain or loss on foreign exchange, earnings or loss from discontinued operations, changes in value of investments carried at fair value, gains and losses on disposition of assets, and other typically non-recurring or unusual items. The Corporation adjusts for these factors as they may be non-cash, unusual in nature, and are not factors used by management for evaluating the operating performance of the Corporation. The Corporation believes that presentation of this measure will enhance an investor’s understanding of the Corporation’s operating performance. Adjusted EBIT is not intended to be representative of cash provided by operating activities or results of operations determined in accordance with U.S. GAAP and can be impacted positively or negatively by these items. A reconciliation of Adjusted EBIT to net earnings is set out in Schedule "F". Adjusted Net Earnings and Adjusted EPS Adjusted Net Earnings is a non-GAAP financial measure used by many investors to compare net earnings from operations without the effects of certain volatile primarily non-cash items that generally have no current economic impact or items such as acquisition expenses or certain litigation expenses that are viewed as not directly related to a company’s operating performance. The Corporation uses Adjusted Net Earnings to assess its performance without the effects of (as applicable): gains or losses on foreign exchange, foreign exchange forward contracts, interest rate swaps, acquisition and transition costs (including costs related to the 2023 strategic review of the Corporation’s renewable energy business), one-time costs of arranging tax equity financing, certain litigation expenses and write down of intangibles and property, plant and equipment, earnings or loss from discontinued operations, unrealized mark-to-market revaluation impacts, costs related to management succession and executive retirement, costs related to prior period adjustments due to changes in tax law, costs related to condemnation proceedings, changes in value of investments carried at fair value, gains and losses on disposition of assets, and other typically non-recurring or unusual items, as these are not reflective of the performance of the underlying business of the Corporation. The Corporation believes that analysis and presentation of net earnings or loss on this basis will enhance an investor’s understanding of the operating performance of its businesses. Adjusted Net Earnings is not intended to be representative of net earnings or loss determined in accordance with U.S. GAAP and can be impacted positively or negatively by these items. A reconciliation of Adjusted Net Earnings to net earnings can be found under the heading “Non-GAAP Financial Measures - Reconciliation of Adjusted Net Earnings to Net Earnings” in the 2023 Annual MD&A, which section is incorporated by reference herein. Adjusted EPS is calculated by dividing Adjusted Net Earnings by the weighted average number of common shares outstanding during the applicable period.

Our contractual arrangements with Morrow Sodali provide for additional fees to be payable in certain circumstances. All costs of solicitation will be borne by Algonquin. “Algonquin”, the “Corporation”, “we”, and “our” means Algonquin Power & Utilities Corp. unless otherwise indicated. “Shareholder”, “you”, and “your” means a holder of common shares (“Common Shares”) of Algonquin. In this Circular, unless otherwise indicated, all references to “$” are to Canadian dollars and all references to “US$” are to U.S. dollars. The information in this Circular is presented as of April 8, 2024 unless otherwise stated. Approval of this Circular The Board of Directors has approved the content and delivery of this Circular.

A simple majority of the votes cast by proxy or at the Meeting will constitute approval of matters voted on at the Meeting. On April 8, 2024, the record date established for notice of the Meeting, there were 689,658,549 outstanding Common Shares eligible to vote. Each outstanding Common Share is entitled to one vote on each item of business at the Meeting. All Shareholders as of the record date are entitled to vote at the Meeting, or any adjournment or postponement thereof, either at the Meeting or by proxy as described in this Circular. To the knowledge of the directors and officers of the Corporation, as of the date of this Circular, no person or company beneficially owned, directly or indirectly, or controlled or directed 10% or more of the Common Shares.

2024 Management Information Circular 9 Delivery of Meeting Materials Notice-and-access As permitted by the Canadian Securities Administrators and pursuant to an exemption from the management proxy solicitation requirement received by the Corporation from the Director appointed under the Canada Business Corporations Act, the Corporation is using “notice-and- access” to deliver proxy-related materials (such as this Circular and the Corporation’s 2023 Annual Report, containing the Corporation’s audited consolidated financial statements and the auditor’s report thereon and the 2023 Annual MD&A (the “Annual Report” and, together with this Circular, the “Meeting Materials”)) to Shareholders. Rather than receiving a paper copy of the Meeting Materials in the mail, Shareholders of record as of the record date for the Meeting have access to them online. Shareholders will receive a notice package (the “Notice Package”) containing information about the matters to be addressed at the Meeting and the notice-and- access process, a form of proxy (if you are a registered Shareholder) or a voting instruction form (if you are a non-registered Shareholder), and instructions on how to vote your Common Shares. Where a Shareholder has previously consented to electronic delivery, the Notice Package will be sent to the Shareholder electronically. The Notice Package will be mailed to Shareholders from whom consent to electronic delivery has not been obtained. Shareholders are reminded to review this Circular prior to voting. The Corporation anticipates that notice-and-access will directly benefit the Corporation through a substantial reduction in both postage and printing costs and will also promote environmental responsibility by decreasing the large volume of paper documents generated by printing Meeting Materials. Shareholders with questions regarding notice-and-access can call TSX Trust, the Corporation’s transfer agent, toll-free at 1-888-433-6443. Accessing the Meeting Materials electronically Electronic copies of the Meeting Materials are available online at www.meetingdocuments.com/tsxt/AQN, on SEDAR+ (“SEDAR”) at www.sedarplus.ca, or on the EDGAR system (“EDGAR”) of the Securities and Exchange Commission (“SEC”) at www.sec.gov. All references to websites are for your information only. The information contained or linked through any website is not part of, and is not incorporated by reference into, this Circular. How to request paper copies of the Meeting Materials Shareholders may obtain paper copies of the Meeting Materials free of charge by following the instructions provided in the Notice Package or by emailing TSX Trust, the Corporation’s transfer agent, at tsxt-fulfilment@tmx.com. Shareholders may request paper copies of the Meeting Materials for up to one year from the date that this Circular was filed on SEDAR. In order to receive paper copies of the Meeting Materials in advance of the deadline for submission of voting instructions and the date of the Meeting, your request must be received by TSX Trust, the Corporation’s transfer agent, by May 21, 2024. Please note that if you request a paper copy of the Meeting Materials, you will not receive a new form of proxy or voting instruction form, and therefore you should retain the forms included in the Notice Package in order to vote.

ALGONQUIN | LIBERTY 10 Voting instructions You can vote your Common Shares by proxy or in person at the Meeting. Please follow the instructions in this section based on whether you are a registered or non-registered Shareholder. If you have questions or require assistance with voting your Common Shares, you may contact our proxy solicitation agent: Morrow Sodali North American Toll-Free Number: 1-888-777-1679 Collect Calls Outside North America: 1-289-695-3075 Email: assistance@morrowsodali.com Non-Registered Shareholders You are a non-registered Shareholder (“Non-Registered Holder”) if you hold Common Shares through an intermediary such as a securities broker, trustee, financial institution, or depository. Non-Registered Holders should carefully follow the instructions of their intermediaries and their intermediaries’ service companies regarding the voting process. The Corporation has distributed copies of the materials related to the Meeting to intermediaries for further distribution to Non-Registered Holders. Intermediaries are required to forward the materials related to the Meeting to Non-Registered Holders and seek voting instructions from them unless a Non-Registered Holder has waived the right to receive the materials related to the Meeting. Intermediaries often use service companies to forward the materials related to the Meeting to Non-Registered Holders. Generally, Non-Registered Holders who have not waived the right to receive the materials related to the Meeting will: be given a voting instruction form which must be completed and signed by the Non-Registered Holder in accordance with the instructions on the form (which may, in some cases, permit the completion of the voting instruction form by internet, telephone, or fax); or less typically, be given a proxy which has already been signed by the intermediary, restricted as to the number of Common Shares beneficially owned by the Non-Registered Holder, but which has not otherwise been completed. The Non-Registered Holder who wishes to submit the proxy should properly complete and deposit it with the Corporation or TSX Trust, as described in the notice of meeting. This proxy need not be signed by the Non-Registered Holder. The purpose of these procedures is to permit Non-Registered Holders to direct the voting of the Common Shares which they beneficially own. Voting in person at the Meeting We do not have unrestricted access to the names of our Non-Registered Holders. If you attend the Meeting, we may have no record of your shareholdings or entitlement to vote unless your intermediary has appointed you as a proxyholder. Should a Non-Registered Holder who receives a proxy signed by the intermediary wish to attend and vote at the Meeting in person (or have another person attend and vote on their behalf), the Non-Registered Holder should: Strike out the names of the persons named in the proxy and insert your name (or the name of such other person) in the blank space provided; Leave the voting instructions section blank because you (or such other person) will be voting at the Meeting; and When you arrive (or such other person arrives) at the Meeting, meet with a representative at the registration table. A Non-Registered Holder who receives a voting instruction form should follow the instructions for voting in person that are provided on the voting instructions form. The Chair of the Meeting reserves the right to accept late proxies and to waive the cut-off date with or without notice, but is under no obligation to accept or reject any late proxy. Changing your vote If you have already sent your completed voting instruction form to your intermediary and you change your mind about your voting instructions, or want to vote at the Meeting, contact your intermediary to find out whether this is possible and what procedure to follow.

2024 Management Information Circular 11 Registered Shareholders You are a registered Shareholder if you have a share certificate for Common Shares and they are registered in your name or if you hold Common Shares through direct registration. You will find a form of proxy included in the Notice Package. Voting by proxy Voting by proxy means you are giving the person or persons named in your form of proxy the authority to attend the Meeting, or any adjournment, and vote your Common Shares for you. Please mark your vote, sign, date, and follow the return instructions provided in the form of proxy. By doing this, you are giving the Directors or officers of Algonquin who are named in the form of proxy the authority to vote your Common Shares at the Meeting, or any adjournment or postponement thereof. You can choose another person or company to be your proxyholder, including someone who is not a Shareholder. You can do so by inserting the name of the person or company in the blank space provided on the form of proxy. If you appoint someone else, he or she must be present at the Meeting to vote your Common Shares. Voting at the Meeting You do not need to complete or return your form of proxy if you intend to vote at the Meeting. Simply attend the Meeting and present yourself to a representative at the registration table. The Chair of the Meeting reserves the right to accept late proxies and to waive the cut-off date with or without notice, but is under no obligation to accept or reject any late proxy. Changing your vote A registered Shareholder who has submitted a proxy may revoke the proxy by delivering a signed instrument in writing, including another proxy bearing a later date, executed by the registered Shareholder or his or her attorney authorized in writing or, if the registered Shareholder is a corporation, by an officer or attorney thereof duly authorized, by depositing such instrument with TSX Trust before the deadline for filing proxies, or in any other manner permitted by law. The revocation of a proxy does not, however, affect any matter on which a vote has been taken prior to the revocation. How your proxy will be voted On the form of proxy, you can indicate how you want your proxyholder to vote your Common Shares, or you can let your proxyholder decide for you. If you have specified on the form of proxy how you want your Common Shares to be voted on a particular item, then your proxyholder must follow your instructions. If you have not specified on the form of proxy how you want your Common Shares to be voted on a particular item, then your proxyholder can vote your Common Shares as he or she sees fit. Processing the votes Proxies are counted by our transfer agent, TSX Trust. TSX Trust respects the confidentiality of individual Shareholder votes except if the Shareholder clearly intends to communicate his or her individual position to the board or management, or disclosure is necessary to comply with legal requirements. Voting results Following the Meeting, a report on the voting results will be available on the Investors section of our website at www.algonquinpower.com and will be filed with securities regulators on SEDAR at www.sedarplus.ca and on EDGAR at www.sec.gov.

Electronic copies of the Annual Report are available at www.meetingdocuments.com/tsxt/AQN, on Algonquin’s website at www.algonquinpower.com, on SEDAR at www.sedarplus.ca, and on EDGAR at www.sec.gov. 2. Appointment of auditor The Audit & Finance Committee of the Board has reviewed the performance of Ernst & Young LLP, including its independence relating to the audit, and recommends the re-appointment of Ernst & Young LLP as the independent external auditor of the Corporation for the ensuing year. Ernst & Young LLP has been the auditor of the Corporation since 2013. The aggregate fees billed by Ernst & Young LLP during the years ended December 31, 2023 and December 31, 2022 were as follows:

2024 Management Information Circular 13 3. Election of directors The Corporation’s Articles of Incorporation provide that the board is to consist of a minimum of three and a maximum of 20 directors. The number of directors to be elected at the Meeting is nine. The nine individuals nominated for election as directors are listed in the “Director nominees” section beginning on page 18 of this Circular. Directors are elected annually for a term ending at the conclusion of the next annual meeting of Shareholders. Management does not anticipate that any of the nominees will be unable to serve as a director. If that should occur for any reason prior to the Meeting, the persons named in the enclosed form of proxy reserve the right to vote for another nominee at their discretion. The Corporation has a by-law in place setting out advance notice requirements for the nomination of directors (the “Advance Notice By-Law”). The purposes of the Advance Notice By-Law are to: (i) facilitate an orderly and efficient process for the nomination and election of directors by Shareholders; (ii) ensure that all Shareholders receive adequate notice of director nominations and sufficient information with respect to all nominees; and (iii) allow Shareholders to make an informed vote on the election of directors after having been afforded reasonable time for appropriate deliberation. The Advance Notice By-Law fixes a deadline by which Shareholders must submit nominations for election of directors prior to any meeting of Shareholders at which directors are to be elected and sets forth the information that a Shareholder must include in the notice to the Corporation in order for a nominee to be eligible for election as a director. The deadline for the receipt of nominations for election of directors at the Meeting is April 25, 2024. The Advance Notice By-Law prescribes the proper written form for a Shareholder’s notice as well as additional requirements in connection with nominations. A copy of the Advance Notice By-Law is available on the Corporation’s website at www.algonquinpower.com and on SEDAR at www.sedarplus.ca. No person will be eligible for election as a director unless nominated in accordance with the provisions of the Advance Notice By-Law. The board may, in its sole discretion, waive any requirements of the Advance Notice By-Law. In the absence of a contrary instruction, the persons named in the enclosed form of proxy intend to vote FOR the election as directors the proposed nominees whose names are set out in the “Director nominees” section of this Circular starting on page 18. 4. Amendments to the Share Unit Plan The board adopted the Share Unit Plan with effect from January 2011 and it was most recently amended in 2017. Among the amendments made in 2017 was an increase to the number of Common Shares reserved for issuance from treasury under the Share Unit Plan from 500,000 to 7,000,000. Shareholders approved this increase on June 8, 2017. At the Meeting, Shareholders will be asked to consider and, if thought advisable, pass a resolution in the form below (the “Share Unit Plan Amendment Resolution”) to approve amendments to the Share Unit Plan, including to increase the maximum number of Common Shares issuable from treasury under the Share Unit Plan from 7,000,000 to 14,000,000. The proposed increase is to allow the Corporation to continue to use performance share units (“PSUs”) and restricted share units (“RSUs”) as components of long-term compensation. Information on the Share Unit Plan’s dilution, burn rate, and overhang for the last three years is shown on page 66. As of April 11, 2024, 2,979,838 Common Shares have been issued from treasury under the Share Unit Plan, representing approximately 0.43% of the outstanding Common Shares, and there were 4,020,162 Common Shares remaining available for issuance from treasury under the Share Unit Plan. As of April 11, 2024, there were an aggregate of 3,774,916 PSUs and RSUs outstanding which, if they vested at target (in the case of PSUs) and were settled in Common Shares issued from treasury, would result in the issuance of an equal number of Common Shares, or approximately 0.55% of the issued and outstanding Common Shares. The proposed increase in the number of Common Shares issuable from treasury under the Share Unit Plan will not result in an increase in the aggregate number of Common Shares reserved for issuance pursuant to all of the Corporation’s security-based compensation arrangements. The maximum number of Common Shares issuable under the Corporation’s stock option plan (the “Option Plan”) is equal to 8% of the outstanding Common Shares less the number of Common Shares issuable from treasury under all other security-based compensation plans of the Corporation. Accordingly, any increase in the number of Common Shares issuable from treasury under the Share Unit Plan will automatically result in a corresponding decrease in the number of Common Shares issuable under the Option Plan.

ALGONQUIN | LIBERTY 14 The other proposed amendments to the Share Unit Plan are to: provide for the market value of PSUs and RSUs on the grant date to be based on the volume-weighted average price of the Common Shares on the Toronto Stock Exchange (“TSX”) for the five trading days prior to the grant, thereby aligning with common market practice and the principles regarding the pricing of awards set out in the TSX’s Guide to Security Based Compensation Arrangements; allow for pro-rated vesting of PSUs upon a qualifying retirement of a participant in the Share Unit Plan; clarify the vesting of PSUs and RSUs during a period of notice of termination to reflect recent developments in Canadian employment law; clarify that the vesting date of PSUs coincides with the last day of the applicable performance period; clarify that the board has direct responsibility for administering the Share Unit Plan with respect to members of the Corporation’s executive team; align the Share Unit Plan’s amendment provisions with the TSX’s requirements; and make other non-substantive amendments of a “housekeeping” nature. The TSX has conditionally approved these amendments, subject to approval by Shareholders at the Meeting. The Share Unit Plan is described in more detail under the heading, “The Share Unit Plan” beginning on page 62 and, as proposed to be amended, in Schedule “A” – Description of the Share Unit Plan. A blacklined version of the Share Unit Plan showing all proposed amendments is attached as Schedule “B”. At the meeting, Shareholders will have the opportunity to vote on the Share Unit Plan Amendment Resolution, as follows: RESOLVED that: the Performance and Restricted Share Unit Plan for Employees of Algonquin Power & Utilities Corp. (the “Corporation”) and its Participating Affiliates (the “Share Unit Plan”) be amended as set out in Schedule “B” to the Management Information Circular of the Corporation for the annual meeting of shareholders held on June 4, 2024, including that the maximum number of common shares of the Corporation issuable from treasury upon the vesting and settlement of performance share units and restricted share units issued under the Share Unit Plan be increased from 7,000,000 common shares to 14,000,000 common shares; and any director or officer of the Corporation is hereby authorized to do all things and execute all instruments and documents necessary or desirable to carry out the foregoing. In order to be effective, the Share Unit Plan Amendment Resolution must be approved by a simple majority of the votes cast by Shareholders in respect thereof at the Meeting. If Shareholders do not approve the amendments to the Share Unit Plan, the maximum number of Common Shares issuable from treasury under the Share Unit Plan will remain at 7,000,000 and the other proposed amendments will not be effective. The board has determined that the proposed amendments to the Share Unit Plan are in the best interest of the Corporation and the Shareholders and recommends that Shareholders vote FOR the Share Unit Plan Amendment Resolution. In the absence of a contrary instruction, the persons named in the enclosed form of proxy intend to vote FOR the Share Unit Plan Amendment Resolution.

2024 Management Information Circular 15 5. Amendment to the ESPP The board adopted the ESPP with effect from June 2011 and it was most recently amended in 2020. Among the amendments made in 2020 was an increase to the number of Common Shares reserved for issuance from treasury under the ESPP from 2,000,000 to 4,000,000. Shareholders approved this increase on June 4, 2020. At the Meeting, Shareholders will be asked to consider and, if thought advisable, pass a resolution in the form below (the “ESPP Amendment Resolution”) to approve an amendment to the ESPP to increase the maximum number of Common Shares issuable from treasury under the ESPP from 4,000,000 to 6,500,000. Since the 2020 amendment, there has been an increase in the number of employees eligible to participate in the ESPP and an increase in the rate of issuances from treasury under the ESPP. The current limit of 4,000,000 Common Shares does not provide sufficient capacity to accommodate the increased participation and purchases. The purpose of the proposed amendment to the ESPP is to provide the Corporation with such capacity and facilitate higher levels of employee ownership in the Corporation, which strengthens the alignment of employees’ interests with those of Shareholders. Information on the ESPP’s burn rate and overhang for the last three years is shown on page 68. As of April 11, 2024, 3,377,535 Common Shares have been issued from treasury under the ESPP, representing approximately 0.49% of the outstanding Common Shares, and 622,465 Common Shares remain available for issuance from treasury under the ESPP, representing approximately 0.09% of the outstanding Common Shares. The proposed maximum of 6,500,000 Common Shares represents approximately 0.94% of the outstanding Common Shares. The proposed increase in the number of Common Shares issuable from treasury under the ESPP will not result in an increase in the aggregate number of Common Shares reserved for issuance pursuant to all of the Corporation’s security-based compensation arrangements. The maximum number of Common Shares issuable under the Option Plan is equal to 8% of the outstanding Common Shares less the number of Common Shares issuable from treasury under all other security-based compensation plans of the Corporation. Accordingly, any increase in the number of Common Shares issuable from treasury under the ESPP will automatically result in a corresponding decrease in the number of Common Shares issuable under the Option Plan. The TSX has conditionally approved this amendment, subject to approval by Shareholders at the Meeting. The ESPP is described in more detail under the heading “The ESPP” beginning on page 67 of this Circular. The complete text of the ESPP is available on the Corporation’s website at www.algonquinpower.com. At the Meeting, Shareholders will have the opportunity to vote on the ESPP Amendment Resolution, as follows: RESOLVED that: 1. the Employee Share Purchase Plan (the “ESPP”) of Algonquin Power & Utilities Corp. (the “Corporation”) be amended such that the maximum number of common shares of the Corporation issuable from treasury under the ESPP be increased from 4,000,000 common shares to 6,500,000 common shares; and 2. any director or officer of the Corporation is hereby authorized to do all things and execute all instruments and documents necessary or desirable to carry out the foregoing. In order to be effective, the ESPP Amendment Resolution must be approved by a simple majority of the votes cast by Shareholders in respect thereof at the Meeting. If Shareholders do not approve the amendment to the ESPP, the maximum number of Common Shares issuable from treasury under the ESPP will remain at 4,000,000. The board has determined that the proposed amendment to the ESPP is in the best interest of the Corporation and the Shareholders and recommends that Shareholders vote FOR the ESPP Amendment Resolution. In the absence of a contrary instruction, the persons named in the enclosed form of proxy intend to vote FOR the ESPP Amendment Resolution.

ALGONQUIN | LIBERTY 16 6. Amendment to the DSU Plan The board adopted the DSU Plan with effect from June 2011 and it was most recently amended in 2016. Among the amendments made in 2016 was an increase to the number of Common Shares reserved for issuance from treasury under the DSU Plan from 200,000 to 1,000,000. Shareholders approved this increase on June 9, 2016. At the Meeting, Shareholders will be asked to consider and, if thought advisable, pass a resolution in the form below (the “DSU Plan Amendment Resolution”) to approve an amendment to the DSU Plan to increase the maximum number of Common Shares issuable from treasury under the DSU Plan from 1,000,000 to 2,000,000. In addition, the board has approved certain non-substantive amendments of a “housekeeping” nature to the DSU Plan that are within the authority of the board under the amending provision of the DSU Plan and therefore do not require Shareholder approval. The purpose of the proposed amendment to the DSU Plan is to allow the board to continue to use deferred share units (“DSUs”) as a significant component of director compensation, which strengthens the alignment of directors’ interests with those of Shareholders. The Chair of the Board of Directors (“Board Chair”) receives 50% of his annual retainer in the form of DSUs and the other directors receive at least 57% of their annual retainers in the form of DSUs. Information on the DSU Plan’s dilution, burn rate, and overhang for the last three years is shown on page 44. As of April 11, 2024, 93,866 Common Shares have been issued from treasury under the DSU Plan, representing approximately 0.01% of the outstanding Common Shares, and there were 777,584 DSUs outstanding representing approximately 0.11% of the outstanding Common Shares which are redeemable for an equal number of Common Shares after the directors holding such DSUs leave the board. As of April 11, 2024, 906,134 Common Shares remain available for issuance from treasury under the DSU Plan, representing approximately 0.13% of the outstanding Common Shares. The proposed maximum of 2,000,000 Common Shares represents approximately 0.29% of the outstanding Common Shares. The proposed increase in the number of Common Shares issuable from treasury under the DSU Plan will not result in an increase in the aggregate number of Common Shares reserved for issuance pursuant to all of the Corporation’s security-based compensation arrangements. The maximum number of Common Shares issuable under the Option Plan is equal to 8% of the outstanding Common Shares less the number of Common Shares issuable from treasury under all other security-based compensation plans of the Corporation. Accordingly, any increase in the number of Common Shares issuable from treasury under the DSU Plan will automatically result in a corresponding decrease in the number of Common Shares issuable under the Option Plan. The TSX has conditionally approved this amendment, subject to approval by Shareholders at the Meeting. The DSU Plan is described in more detail under the heading, “The DSU Plan” beginning on page 44 and in Schedule “C” – Description of the DSU Plan. The complete text of the DSU Plan is available on the Corporation’s website at www.algonquinpower.com. At the Meeting, Shareholders will have the opportunity to vote on the DSU Plan Amendment Resolution, as follows: RESOLVED that: 1. the Algonquin Power & Utilities Corp. Directors’ Deferred Share Unit Plan (the “DSU Plan”) be amended such that the maximum number of common shares of the Corporation issuable from treasury under the DSU Plan be increased from 1,000,000 common shares to 2,000,000 common shares; and 2. any director or officer of the Corporation is hereby authorized to do all things and execute all instruments and documents necessary or desirable to carry out the foregoing. In order to be effective, the DSU Plan Amendment Resolution must be approved by a simple majority of the votes cast by Shareholders in respect thereof at the Meeting. If Shareholders do not approve the amendment to the DSU Plan, the maximum number of Common Shares issuable from treasury under the DSU Plan will remain at 1,000,000. The board has determined that the proposed amendment to the DSU Plan is in the best interest of the Corporation and the Shareholders and recommends that Shareholders vote FOR the DSU Plan Amendment Resolution. In the absence of a contrary instruction, the persons named in the enclosed form of proxy intend to vote FOR the DSU Plan Amendment Resolution.

2024 Management Information Circular 17 7. Advisory vote on executive compensation The board has adopted a policy to provide Shareholders with an annual advisory vote on executive compensation based on the model “Say on Pay” policy for boards of directors published by the Canadian Coalition for Good Governance. Shareholders voted 93.86% in favour of the board’s approach to executive compensation at the 2023 annual meeting of Shareholders. The board believes that Shareholders should have the opportunity to fully understand the objectives, philosophy, and principles the board has used in its approach to executive compensation decisions and to have an advisory vote on the board’s approach to executive compensation. Shareholders should review the “HRCC’s Letter to Shareholders” beginning on page 46, the “Corporate governance practices” section beginning on page 27, and the “Compensation governance” section beginning on page 32 of this Circular before voting on this matter. The “Compensation discussion and analysis” section beginning on page 51 discusses the board’s compensation philosophy and approach to executive compensation, what our named executive officers (“Named Executive Officers” or “NEOs”, as defined under the heading “Named Executive Officer compensation” on page 54) are paid, and how their compensation is determined. This disclosure has been approved by the board on the recommendation of the board’s Human Resources and Compensation Committee (“HRCC”). We encourage any Shareholder who has comments on the board’s approach to executive compensation to forward these comments to the Chair of the HRCC at Algonquin Power & Utilities Corp., 354 Davis Road, Suite 100, Oakville, Ontario, Canada L6J 2X1, Attention: Corporate Secretary, or by email to board@apucorp.com. At the Meeting, Shareholders will have the opportunity to vote on the board’s approach to executive compensation through consideration of the following advisory resolution: “RESOLVED, on an advisory basis and not to diminish the role and responsibilities of the Board of Directors, that the shareholders of Algonquin Power & Utilities Corp. (the “Corporation”) accept the approach to executive compensation disclosed in the management information circular of the Corporation delivered in advance of the June 4, 2024 annual meeting of the shareholders of the Corporation.” As this is an advisory vote, the results will not be binding on the board. However, the board will take into account the results of the vote, together with feedback received from Shareholders, in considering its approach to executive compensation in the future. In the absence of a contrary instruction, the persons designated in the form of proxy intend to vote FOR the advisory resolution on executive compensation.

ALGONQUIN | LIBERTY 18 Director nominees The following pages set forth the name and background information of the nine persons proposed for nomination for election as directors, including the name and jurisdiction of residence of such person, the person’s principal occupation or employment for the past five years, a summary of his or her experience, the year such person was first elected as a director, the director’s attendance at meetings of the board and its committees in 2023, other public company directorships held during the last five years, and the number and value of Common Shares and DSUs beneficially owned, directly or indirectly, or over which control or direction is exercised, by such person. The aggregate number of Common Shares held by the director nominees as of April 8, 2024 is 208,666, which represents 0.03% of the issued and outstanding Common Shares. Director equity ownership guideline Non-employee directors are subject to the Non-Employee Director Equity Ownership Guideline. This guideline requires each non-employee director to hold an equity interest in the Corporation worth four times the annual director retainer or annual board chair retainer, as applicable, by the later of: (i) the fifth anniversary of his or her appointment or election to the board; or (ii) the third anniversary of the most recent increase in the annual director retainer or board chair retainer, as applicable. Notwithstanding the preceding sentence, if a non-employee director’s equity ownership falls below the guideline amount due to a decline in the market price of the Common Shares, such director will have three years to restore compliance. During such three-year period, such director’s equity holdings will be valued at the higher of acquisition cost or market value. If a non-employee director does not comply with the guideline by the applicable deadline, such director must use up to one-third of the cash portion of the annual retainer to purchase additional Common Shares. In addition, the HRCC may require such director to elect to receive up to one-third of the annual retainer otherwise payable in cash in the form of DSUs. Compliance with the Non-Employee Director Equity Ownership Guideline is measured as of the first trading day of the year (i.e., January 2, 2024). Based on the values of the annual director retainer and board chair retainer in effect on that date, the equity ownership requirement applicable to the Board Chair is US$1,270,000 and to each other non-employee director is US$960,000. For non-employee directors, Common Shares and DSUs are considered equity holdings for the purposes of determining compliance with the Non-Employee Director Equity Ownership Guideline. The numbers of Common Shares and DSUs shown in the director nominee profiles beginning on page 21 are as of January 2, 2024 and, in accordance with the Non-Employee Director Equity Ownership Guideline, are valued using the volume-weighted average price of the Common Shares on the TSX for the 20 trading days prior to that date, which was $8.4966. The equity ownership requirements shown in the director nominee profiles have been converted to Canadian dollars using a rate of $1.3316/US$1.00 as of January 2, 2024.

2024 Management Information Circular 19 Highlights – board nominees 33% of director nominees are women. 8 of 9 nominees are independent. 3.67 years average tenure of the nominees. Majority voting for election of directors In 2022, the Canada Business Corporations Act was amended to codify a majority voting standard for the election of directors of corporations governed by that statute, such as Algonquin. These amendments allow shareholders of applicable corporations to vote “for” or “against” each director nominee in an election where the number of nominees is equal to the number of directors to be elected (referred to as an “uncontested election”). Prior to the amendments, shareholders could only cast their votes “for” a director nominee or “withhold” them from a director nominee, which meant that a nominee could have been elected as a director with less than a majority of votes cast in his or her favour. To address this issue, prior to the amendments coming into force, the Corporation had a majority voting policy which required a director to offer to resign if he or she received more “withhold” votes than votes in favour in an uncontested election. During the period in which the majority voting policy was in place, all director nominees received a majority “for” vote at meetings of Shareholders. As of the date of this Circular, the board and management believe that the election of directors at the Meeting will be an uncontested election. In that case, each director nominee will only be elected to the board if he or she receives more “for” votes than “against” votes at the Meeting. The Corporation will issue a news release after the Meeting disclosing the detailed voting results for each director nominee.

Corporate governance practices This section discloses Algonquin's corporate governance practices in accordance with National Instrument 58-101 – Disclosure of Corporate Governance Practices. Corporate governance highlights The positions of Board Chair and Chief Executive Officer (“CEO”) are separate. The Board Chair and the chairs of each of the board’s committees are independent in accordance with applicable standards in National Instrument 52-110 – Audit Committees (“NI 52-110”) as well as New York Stock Exchange (“NYSE”) corporate governance standards applicable to boards of directors (the “NYSE Standards”). The board oversees the Corporation’s strategy and actively participates in strategic planning processes which result in Algonquin’s strategic plan. The board oversees and actively participates in the Corporation’s strategic planning processes. The board has written position descriptions for the Board Chair, the committee chairs, and the CEO. New directors are recruited on the basis that they will make a strong contribution and provide the diversity, background, skills, and experience needed by the board. New directors participate in a formal orientation process. Directors are provided support for continuing education to maintain a high level of understanding of, and expertise in, the businesses, investments, and risks of the Corporation to enhance their contributions as directors. Creating a culture of integrity begins with the tone from the top. Directors, officers, and employees are required to annually complete an online ethics and policy training module or to sign an acknowledgment that they have reviewed and understood the Corporation’s Code of Business Conduct and Ethics (the “Code of Conduct”). All meetings of the board and all committees have in-camera sessions during which management is not present. Each of the board’s standing committees meets in camera at each of its meetings with senior leaders other than the CEO. These in-camera sessions in the case of the Audit & Finance Committee, are with the Chief Financial Officer and the Vice President, Internal Audit (separately); in the case of the Corporate Governance Committee, with the Chief Legal Officer; in the case of the HRCC, with the Chief Human Resources Officer; and in the case of the Risk Committee, with the Chief Financial Officer and the Chief Legal Officer. The board is exposed to levels of management within the Corporation in addition to executive management, which facilitates effective succession planning. The board annually assesses its performance in order to identify ways to improve its effectiveness and the performance of the Board Chair, committee chairs, individual directors, and the committees. The board has a policy to annually provide Shareholders with an advisory vote on executive compensation. The board has adopted a compensation clawback policy. The board has adopted a board retirement policy. The board has adopted a diversity policy. 2024 Management Information Circular 27

Board of Directors Algonquin's Articles of Incorporation currently provide that the board have a minimum of three and a maximum of 20 directors. Within those parameters, the board is authorized to determine the number of directors by resolution from time to time. The board has determined that the number of directors to be elected at the Meeting is nine. Independence The board has determined that all director nominees, other than Mr. Huskilson, are independent in accordance with applicable standards in NI 52-110 and the NYSE Standards. Mr. Huskilson is not independent because he is the Interim CEO of the Corporation. Independent chair Mr. Moore, the Board Chair, is independent within the meaning of applicable standards in NI 52-110 and the NYSE Standards. The Board Chair must be independent pursuant to the written position description. Mandate The board has a written mandate to set the strategic direction of the Corporation and to oversee its implementation by management. A copy of the Mandate of the Board of Directors is provided in Schedule “D” hereto and is also available on the Corporation’s website at www.algonquinpower.com. Direct involvement in the strategic planning process Executive management, in collaboration with the board, works to develop and refine a strategic plan through, among other things, participation in strategic planning meetings each year. Strategic planning includes consideration of both internal and external expert advice. Oversight of the Corporation’s strategy is one of the primary roles of the board, as corporate strategy directly influences short- and long-term objectives. Beginning in May 2023, the board undertook a strategic review of the Corporation’s renewable energy business with the objective of enhancing Shareholder value. The board established a Strategic Review Committee (“SRC”) comprised entirely of independent directors to lead the review. The SRC, with support from management and external legal and financial advisors, directed the identification, modelling, and assessment of various strategic alternatives. The strategic review concluded in August 2023, and the SRC was disbanded, following the SRC’s recommendation to the board that the Corporation should pursue a sale of the renewable energy business. The board accepted the SRC’s recommendation. The sale process is ongoing as of the date of this Circular. Risk management The board is responsible for overseeing the implementation by management of appropriate systems to identify, assess, report, and manage the principal business and operational risks faced by the Corporation. The board has established the Risk Committee (see disclosure on page 35 under the heading "Committees of the board") to assist the board in the fulfillment of these duties. The board is assisted in its oversight of financial and accounting controls and risks by the Audit & Finance Committee, of human resources and compensation risks by the HRCC, and of ESG, climate change, and sustainability risks by the Corporate Governance Committee. As part of the risk management processes, risk registers have been developed across the organization through ongoing risk identification and risk assessment exercises facilitated by Algonquin’s Enterprise Risk Management (“ERM”) team. Risk information is sourced throughout the organization using a variety of methods, including risk identification interviews, workshops, and surveys. Key risks and associated mitigation strategies are reviewed by the executive-level ERM Council and are presented to the Risk Committee. Significant risk categories assessed include public and employee safety, environment, natural disasters, security (physical and cyber), financial reporting, operations, compliance, privacy, conduct and ethics, supply chain, organizational effectiveness, contracts, budget, capital projects, return on M&A activity, markets, liquidity, strategic, and regulatory. The impact and likelihood of risks are assessed across the organization using a common risk scoring matrix. Financial, reputation, safety and security, reliability, and planned execution implications are among those considered when determining the impact of a potential risk. Risk mitigation priorities are established based upon these risk assessments and incorporated into the development of Algonquin’s strategic and business plans. The development and execution of risk management action plans for the organization’s top risks are actively monitored by the ERM team. Algonquin’s Internal Audit function is responsible for conducting audits to validate and test the effectiveness of controls ALGONQUIN | LIBERTY 28

2024 Management Information Circular 29 for the key risks. Audit findings are discussed with business owners and reported to the Audit & Finance Committee at least quarterly. All material changes to exposures, controls, or mitigation plans of key risks are reported to the ERM team, the ERM Council, and the relevant board committee for consideration. Algonquin’s ERM framework follows the guidance of ISO 31000:2009 and the COSO Enterprise Risk Management Integrated Framework. The board oversees management actions to promote an effective risk governance structure and robust risk management practices. Cyber risk management The board’s oversight of cyber risks is provided primarily by the Risk Committee. The Risk Committee’s mandate includes regularly reviewing the Corporation’s cybersecurity program and related risks. Management considers the security of the Corporation’s critical infrastructure, technology assets, and employee and customer data one of its top priorities, and cybersecurity is one of the ERM program’s important areas of focus. To enable appropriate protection and mitigation of cyber risks, management has implemented several preventative and detective measures, including software and hardware updates, security awareness training, security assessments and audits, multi-factor authentication, data encryption, firewalls and anti-virus software, and monitoring of network activity. Business resilience and preparedness for unplanned events, including response, recovery, and restoration capabilities, are a focus and regularly reviewed. Reports on these management actions are provided to the Risk Committee at least quarterly as part of a standing agenda topic relating to cyber risk. In addition, the Corporation maintains cybersecurity insurance to mitigate the risk of a cybersecurity incident or breach. Under the direction and oversight of the Risk Committee, management is making additional investments in the further enhancement of the Corporation’s enterprise cybersecurity program with the objective of upgrading and aligning organizational cybersecurity capabilities to support security, performance, and decision-making. This consists of several related workstreams, including governance, awareness and training, incident response, data protection, and cybersecurity risk management. Management periodically conducts emergency/disaster recovery and crisis management exercises that include potential cybersecurity events, such as ransomware attacks, and the Corporation’s Cyber Security Incident Response Plan is tested at least annually. The results of those exercises and tests are presented to the Risk Committee and guide future cyber risk management initiatives. Internal controls The board is responsible for monitoring the integrity of our internal controls and management information systems. The board has delegated internal control oversight responsibilities to the Audit & Finance Committee, which includes monitoring the system of internal controls over financial reporting. The Audit & Finance Committee reviews quarterly and annual financial statements and recommends them to the board for approval. Algonquin’s Vice President, Internal Audit has a direct reporting relationship to the Chair of the Audit & Finance Committee and updates the Audit & Finance Committee quarterly on internal audit activities, including assessments of the design and operating effectiveness of the system of internal controls over financial reporting and the preparation of financial statements for external reporting purposes. Succession planning Oversight of management succession planning is within the mandate of the HRCC. The HRCC has responsibility for reviewing succession planning processes and succession plans for key leadership roles at least annually. Succession planning is viewed by the HRCC as an ongoing process for identifying and developing the talent, leadership, and skills necessary for the Corporation to meet future strategic objectives and fulfill key organizational roles in the future. The HRCC is mandated to make recommendations to the board with respect to succession planning, including: (i) policies and principles for the selection and performance review of the executive officers and potential successors to the executive officers; (ii) policies and plans regarding succession in the event of an emergency or the retirement of an executive officer; and (iii) policies and plans related to the appointment, training, and monitoring of potential successors to executive officers. Where employees are considered potential successors, long-term professional development plans are established to further align the employees’ personal development plans with the long-term succession needs of the Corporation. Where no internal succession candidate is identified, the Corporation expects to source a potential successor through external hiring. In this instance, a plan would be established to provide for filling the role on an interim basis pending the external hire. The HRCC also oversees the Corporation’s human resources policies and practices that enable senior management to review the performance of their team members at least annually and develop plans for personal growth and career advancement.

ALGONQUIN | LIBERTY 30 Board and director assessments The board recognizes the value of regular assessments of its effectiveness to identify ways to continuously improve its performance and the performance of the Board Chair, individual directors, and the committees, including the committee chairs. These assessments are conducted annually. The Corporate Governance Committee determines the process by which the assessments will be undertaken. The process may include the use of questionnaires, one-on-one interviews between individual directors and the Board Chair and/or the Chair of the Corporate Governance Committee, or such other processes as the Corporate Governance Committee determines appropriate. Management is invited to participate in the assessment process periodically to provide the directors with an additional perspective on key matters, including the interactions between the board and its committees and management. The Corporate Governance Committee has determined that the use of independent consultants from time to time will supplement and enhance the internal assessment process and provide broader input on board effectiveness. The 2023 assessment process consisted of interviews and written questionnaires. The assessment scope included the following: Assessment of the Board Directors were asked to assess the effectiveness of the board as a whole and the Board Chair, and suggest improvements. Assessment of the Committees Directors were asked to assess the effectiveness of each committee and its chair. Self-assessment Directors were asked to assess their own performance as directors and committee members, including what might make them more effective. Peer assessment Directors were asked to provide comments on the performance of their peer directors. Each year, the results of the assessments are presented to the board and the applicable committee. The results include the identification of any issues arising from the assessments and plans to address any follow-up actions. Director recruitment process The services of a search consulting firm are utilized to assist the Corporation in identifying suitable director candidates. When the Corporation engages a search consulting firm, it requests the development of a list of potential candidates based on the criteria developed by the Corporate Governance Committee for the selection of a new director. Search consulting firms are specifically requested to develop candidate lists that include multiple candidates from each gender and candidates who are diverse on other characteristics or qualities (as described below) compared to the current composition of the board. The search consulting firm screens potential candidates and discusses them with the Corporate Governance Committee, then creates a list of primary candidates. Based on this list, the search consulting firm determines the interest and availability of the candidates to create a final shortlist. This process is carefully designed to provide the best opportunity to identify and attract strong candidates and enhance the board’s diversity on gender and other factors. Each shortlisted candidate is interviewed by the Board Chair, members of the Corporate Governance Committee, and the CEO. Candidates are appointed or nominated for election as directors based on the Corporate Governance Committee’s recommendations to the board. Diversity The board recognizes the benefits of promoting diversity at the board level and throughout the organization. It believes diversity has a positive effect on governance and performance. The board has adopted a diversity policy applicable to the board and executive management (the “Diversity Policy”). The Diversity Policy acknowledges the Corporation’s recognition and support of the benefits of diversity in the composition of the board and executive management. One of the stated objectives of the Diversity Policy is that Diversity (as defined below) be considered in determining the optimal composition of the board and as part of the succession planning process and appointment of members to executive management roles. The Diversity Policy defines “Diversity” as any characteristic or quality that can be used to differentiate groups and people from one another and includes gender, age, race, nationality, culture, language, and other ethnic distinctions (including Aboriginal peoples and members of visible minorities), different abilities (including persons with disabilities), education, and regional and industry experience and expertise. The Diversity Policy requires that the Corporate Governance Committee, as it relates to the Diversity of the board, and the HRCC, as it relates to the Diversity of executive management, periodically assess the effectiveness of existing processes in achieving Algonquin’s Diversity objectives and, if determined advisable, consider measurable objectives for achieving Diversity. An objective of the Diversity Policy is that each gender comprise at least 30% of the directors. As of the date of this Circular, 40.0% of the directors are women and 33.3% of the nominees for election as directors at the Meeting are women. The board also considers gender Diversity in the composition of its committees. The chairs of three out of four committees are currently women and all committees include female directors.

2024 Management Information Circular 31 6 nominees 1 nominee 2 nominees Average tenure of the board nominees is 3.67 years 0 – 4 years 5 – 9 years >9 years The promotion of Diversity in the workplace is a key component of the Corporation’s strategy to become an employer of choice, and the board and management believe that an environment that promotes Diversity positively impacts our ability to attract and retain talent. As it is important that each appointment of an executive officer be made, and be perceived to be made, on the merits of the individual and the needs of the Corporation at the relevant time, the Corporation does not have specific targets related to Diversity in its executive officer or senior management positions. However, the Corporation has adopted a number of initiatives, in addition to the Diversity Policy, to raise awareness regarding the value the Corporation places on Diversity and to measure the organization’s progress in increasing Diversity. When utilizing external recruiters, management requires that recruiters provide gender diverse short-listed candidates for all senior roles recruited. Each year, gender diversity is considered as part of the executive succession planning process to promote the development of women for leadership positions and annually the HRCC, as part of its review of succession planning, considers year-over-year changes in gender diversity both at the enterprise and business unit level. As part of its Diversity program reviews, the HRCC also considers progress with the development of initiatives by the Corporation that support inclusion in the workplace. As of April 18, 2024: (i) women represent 33% of the total workforce of Algonquin and its subsidiaries, including 32% of management positions at or above the senior manager level; and (ii) women represent 29% of the executive team. In addition, based on the self-identification of Algonquin’s directors and executive officers, Aboriginal peoples, members of visible minorities, and persons with disabilities (as each such term is defined in the Employment Equity Act (Canada)) are currently represented in Algonquin’s executive officer positions and on the board as follows: No members of the executive team are members of a visible minority, Aboriginal peoples, or persons with disabilities. Two directors are members of a visible minority, representing 20% of the board, and there are no Aboriginal peoples or persons with disabilities on the board. Director retirement policy The board has adopted a retirement policy for directors to facilitate board renewal. In March 2023, the board approved amendments to the retirement policy to replace the former retirement age of 71 with a tenure limit. The amended policy states that a director may stand for re-election to the board until the 12th annual meeting of Shareholders after his or her initial election or appointment to the board. The amended policy contains a “grandfathering” provision pursuant to which an individual who was serving as a director on the date the amendments were approved may continue to stand for re-election until the later of: (i) the 12th annual meeting of Shareholders after his or her initial election or appointment to the board; or (ii) the annual meeting of Shareholders after he or she reaches the age of 71. In either case, the independent directors may, on the recommendation of the Corporate Governance Committee, waive the obligation to retire if they unanimously determine that it is in the best interests of the Corporation that the applicable director continues to serve. Such a waiver may be granted for a maximum of three additional annual terms. The average tenure of Algonquin’s nine Director nominees is 3.67 years. The board is comprised of a mix of longer-serving directors familiar with the Corporation’s business and history and directors who are newer to Algonquin and bring fresh perspectives to the board.

ALGONQUIN | LIBERTY 32 Directors meet without management At each meeting of the board and its committees, there is an in-camera session during which management is not present. Common memberships on boards of public companies There are currently no common memberships on boards of public companies among the Corporation’s director nominees. Director equity ownership guideline All directors are subject to an equity ownership guideline, which is described on page 18. For the director nominees’ status under the equity ownership guideline, please see their profiles on pages 21 to 25. Nomination of directors The Corporate Governance Committee serves as the director nominating and evaluation committee and recommends new directors for election or appointment to the board. All members of the Corporate Governance Committee are independent. The Corporate Governance Committee is responsible for recommending the list of nominees for election as directors at the Corporation’s annual meeting of Shareholders. The Corporate Governance Committee creates and reviews the criteria for selecting directors by assessing the personal qualities and qualifications of current directors. It also assesses the Corporation’s ongoing needs and circumstances, Diversity, and the overall mix of expertise, experience, and competencies on the board as reflected in the director skills matrix (see page 20). In recruiting new directors, the Corporate Governance Committee considers the Diversity, expertise, experience, and competencies desired for directors and develops a plan for the recruitment of additional director nominees on that basis. Director nominees must, in the opinion of the Corporate Governance Committee, be able to contribute positively to the broad range of issues which come before the board for consideration. Directors must also be able to devote the time necessary to prepare for and attend meetings of the board and committees to which they may be appointed. The Corporate Governance Committee also evaluates the expected turnover of directors in advance of their potential retirement from the board and develops a succession plan that includes creating overlap, where possible, between new directors and retiring directors. On April 18, 2024, the Corporation entered into a co-operation agreement with its largest Shareholder, Starboard Value LP (“Starboard”). Pursuant to the co-operation agreement, among other things the Corporation agreed to nominate Messrs. Carter and Lopez for election as directors at the Meeting. Prior to entering into the agreement with Starboard, members of the Corporate Governance Committee met with Messrs. Carter and Lopez and conducted background checks through an independent search consulting firm as it customarily conducts when engaged in a director recruitment process. Following these interviews and background checks, the Chair of the Corporate Governance Committee recommended to the board the nomination of Messrs. Carter and Lopez for election as directors at the Meeting. Compensation governance The HRCC has responsibility for reviewing the alignment of Algonquin’s compensation programs with the Corporation’s performance, business plans, risk profile, and risk management principles. The HRCC annually reviews and makes recommendations to the board regarding compensation of the CEO and other members of executive management. The HRCC oversees the administration of incentive plans providing for the award of annual incentives, stock options (“Options”), RSUs, and PSUs in accordance with the provisions of the respective plans. In addition, the HRCC annually reviews compensation of the directors, including the Board Chair and the chairs of the committees, and the percentage of directors’ compensation that is paid in the form of DSUs. The HRCC reviews and recommends to the board compensation policies and processes and any new incentive compensation and equity compensation plans or substantive changes to such plans. The HRCC also reviews management succession plans and recommends to the board the appointment and compensation of executive management, including grants of Options, RSUs, and PSUs to those individuals. The HRCC also has responsibility for reviewing, on an annual basis, the performance of the CEO and reviewing with the CEO the performance of the other members of executive management. The HRCC retains the services of an independent advisor to assist in fulfilling its duties. In 2017, the HRCC first retained Hugessen Consulting Inc. (“Hugessen”) as its independent advisor. Hugessen provides counsel on the competitiveness and appropriateness of compensation practices and Algonquin’s comparator groups. The scope of services includes competitive benchmarking of executive and director compensation levels, the review and assessment of the Corporation’s current executive compensation philosophy, policies, and practices, a review of pay and performance comparators, a review of incentive plan design, and a biennial compensation risk assessment. In addition, management of the Corporation has separately engaged Mercer (Canada) Limited (“Mercer”) as an independent compensation consultant to provide data

2024 Management Information Circular 33 services, pension and benefits advice, compensation analysis, and other information required from time to time for the development of compensation recommendations and management of existing programs, due diligence services relating to employee pension and benefits in relation to potential acquisitions, and integration work for employee benefits plans for acquired businesses. Board pre-approval for provision of these services to management is not required given that Mercer has not been the compensation advisor to the HRCC since 2017. Sustainability governance Algonquin is committed to contributing to a sustainable energy and water future. Our aim is to be a top-quartile global utility known for exceptional performance in terms of safety, customer experience, employee engagement, diversity and inclusion, environmental and social responsibility, and financial results. Our focus on sustainability includes a commitment to the Sustainable Development Goals (“SDGs”) published by the United Nations in 2015. We have aligned our approach to sustainability with 10 of the 17 SDGs that are most relevant to our corporate mission, capabilities, and values. Given the industry in which the Corporation operates, Climate Action is one of our top priority SDGs. Algonquin supports the global goal of limiting planetary temperature rise and has established a target to achieve net-zero scope 1 and scope 2 greenhouse gas (“GHG”) emissions by 2050. We are committed to reducing the impact of climate change by deploying emerging technologies and business models to decarbonize our energy portfolio. We have also established the following interim environmental and climate-related targets: Reduce GHG emissions by one million metric tons from 2017 levels – we achieved our target by reducing CO2 emissions by more than 1.4 million metric tons by the end of 2022; Achieve 75% renewable generation by the end of 2023 – we reached 68% by the end of 2023, achieving 90% of our target; and Add 2,000 megawatts of renewable production between 2019 and 2023 – we achieved our target by adding 2,094 megawatts by the end of 2023. Additional information on Algonquin’s commitment to the SDGs, including our specific initiatives and alignment with SDG targets, can be found in our 2023 ESG Report which is available on our website at www.algonquinpower.com. Beyond our commitment to the SDGs, Algonquin has spent considerable effort to align our climate-related risk disclosures with industry best practices. In 2020, we published a Climate Change Assessment in line with the Task Force on Climate-related Financial Disclosures and have continued to evaluate and assess the Corporation’s potential climate risks through this framework. Core to this evaluation are both the physical impacts of climate change on our operations and the potential effects of the energy transition required to achieve a lower-carbon future. Climate-related risks have been identified and integrated into our ERM processes to ensure material risks to the Corporation are appropriately identified, tracked, and ultimately managed. Board-level oversight is an essential element of the integration of sustainability into Algonquin’s corporate strategy. The mandate of the Corporate Governance Committee includes reviewing and making recommendations to the board on sustainability matters and their integration into Algonquin’s business. This includes oversight of the ongoing development and progress of Algonquin’s sustainability plan and initiatives, which are reported to the Corporate Governance Committee quarterly. In addition, the Corporate Governance Committee reviews and provides input into the Corporation’s annual ESG Report and reviews the Corporation’s performance and rankings in various sustainability indices. In addition, material climate-related risks identified through our ERM processes receive oversight from the Risk Committee, which reports on material risks and mitigation activities to the board. The Chief Legal Officer is the executive officer primarily responsible for the Corporation’s sustainability plan, initiatives, and ESG reporting and disclosures. Under her leadership, management provides quarterly updates to the Corporate Governance Committee so that it, and the board as a whole, have reliable and up-to-date information, insights, and performance tracking on key ESG initiatives. The board and management prioritize sustainability across the organization, integrating it into the development and execution of broader strategic priorities. The Corporation’s sustainability team facilitates stakeholder engagement on sustainability topics, supports other functions and departments in integrating ESG principles into their work, collects sustainability data, and is responsible for ESG-related reporting and disclosures, including the Corporation’s annual ESG Report. Algonquin’s Regional Sustainability Councils (“RSCs”) also guide the Corporation’s sustainability efforts. RSCs are comprised of employees from across our regulated utilities and renewable energy groups who work to identify and address sustainability issues relevant to their regions and businesses at the local level. The RSCs have focused their efforts in the following areas: Environmental – reducing their carbon footprints and addressing climate change, water conservation, waste clean-up, and biodiversity enhancement initiatives; and Social – supporting employees and communities with initiatives aimed at improving diversity, equity, and inclusion, education, and resiliency.

ALGONQUIN | LIBERTY 36 New director orientation New directors are provided with a formal orientation to the Corporation that familiarizes them with the businesses, corporate structure, other directors, and key personnel of the Corporation. The orientation process is designed to provide an opportunity for new directors to meet senior management and become familiar with their respective areas of responsibility. New directors receive an in-depth orientation to the Corporation’s executive leaders, businesses, strategy, corporate functions, financial information, and governance practices that allow them to effectively integrate with the operation of the board. New directors are also provided with a reference manual that contains relevant background materials to support their introduction to the Corporation’s business. The reference manual includes the following: Public disclosure documents, including annual reports, recent annual and interim MD&A, financial statements, management information circulars, and annual information forms; Governance documents, including board and committee mandates, key policies, and guidelines; and Other documents such as the Corporation’s strategic plan and annual sustainability reports, the guide to the Corporation’s management structure, succession plans, and minutes of board and committee meetings. Comparison of NYSE corporate governance rules Algonquin is subject to corporate governance requirements prescribed under applicable Canadian corporate governance rules, including the rules of the TSX (“Canadian Rules”). Algonquin is also subject to corporate governance requirements prescribed by the listing standards of the NYSE (the “NYSE Rules”), certain rules and regulations promulgated by the SEC under the Securities Exchange Act of 1934 (the “Exchange Act”), and those applicable rules and regulations mandated by the Sarbanes-Oxley Act of 2002. In particular, Section 303A.06 of the NYSE Listed Company Manual requires Algonquin to have an audit committee that meets the requirements of Rule 10A-3 of the Exchange Act, and Section 303A.011 of the NYSE Listed Company Manual requires Algonquin to disclose any significant ways in which its corporate governance practices differ from those followed by U.S. companies listed on the NYSE. A description of those differences follows. Section 303A.01 of the NYSE Listed Company Manual requires that boards have a majority of independent directors and Section 303A.02 defines independence standards for directors. The board is responsible for determining whether each director is independent. In making this determination, the board has adopted the higher standard of “independence” that applies to each member of the Audit & Finance Committee pursuant to NI 52-110 and Rule 10A-3 of the Exchange Act instead of the definition of independence set forth in the NYSE rules. In applying this definition, the board considers all relationships of its directors, including business, family, and other relationships. Through this process, the board also determines whether each member of its Audit & Finance Committee is independent pursuant to NI 52-110 and Rule 10A-3 of the Exchange Act. Section 303A.04(a) of the NYSE Listed Company Manual requires that all members of the nominating/corporate governance committee be independent as defined in the NYSE Rules. In making this determination, the board has adopted the standard of “independence” applicable to members of the Audit & Finance Committee, rather than the definition set forth in the NYSE Rules. All members of the Corporate Governance Committee are independent directors. Section 303A.05(a) of the NYSE Listed Company Manual requires that all members of the compensation committee be independent as defined in the NYSE Rules. In making this determination, the board has adopted the standard of “independence” applicable to members of the Audit & Finance Committee, rather than the definition set forth in the NYSE Rules. All members of the HRCC are independent directors. Section 303A.07(b)(iii)(A) of the NYSE Listed Company Manual requires, among other things, that the written charter of the audit committee state that the audit committee, at least annually, obtain and review a report by the independent auditor describing the firm’s internal quality control procedures, any material issues raised by the most recent internal quality control review, or peer review, of the firm, or by any inquiry or investigation

2024 Management Information Circular 37 by governmental or professional authorities, within the preceding five years, respecting one or more independent audits carried out by the firm, and any steps taken to deal with any such issues. The Audit & Finance Committee’s written mandate complies with Canadian Rules and requires that prior to the completion of each annual external audit, the Audit & Finance Committee review and discuss with management and the external auditor the adequacy of the Corporation’s internal controls, but does not explicitly require that the Audit & Finance Committee at least annually obtain and review a report from the independent auditor regarding the matters noted above, which is not required by Canadian Rules. Section 303A.08 of the NYSE Listed Company Manual requires that shareholders of a listed company be given the opportunity to vote on all equity compensation plans and material revisions thereto. Algonquin complies with Canadian Rules, which generally require that shareholders approve equity compensation plans. However, the Canadian Rules are not identical to the NYSE Rules. For example, Canadian Rules require shareholder approval of equity compensation plans only when such plans involve the issuance or potential issuance of newly issued securities. In addition, equity compensation plans that do not provide for a fixed maximum number of securities to be issued must have a rolling maximum number of securities to be issued, based on a fixed percentage of the issuer’s outstanding securities, and must also be approved by shareholders every three years. If a plan provides a procedure for its amendment, Canadian Rules require shareholder approval of amendments only where the amendment involves a reduction in the exercise price or purchase price, an extension of the term of an award benefiting an insider, the removal or exceeding of the insider participation limit prescribed by the Canadian Rules, an increase to the maximum number of securities issuable, or is an amendment to the amending provision itself. Section 303A.09 of the NYSE Listed Company Manual requires that a listed company adopt and disclose corporate governance guidelines that address certain topics, including director compensation guidelines. Algonquin has adopted a board mandate, which is the equivalent of corporate governance guidelines, in compliance with the Canadian Rules. Algonquin’s corporate governance guidelines do not address director compensation, but Algonquin provides disclosure about the decision-making process for non-employee director compensation in the annual management information circular. Algonquin has also adopted equity ownership guidelines for non-employee directors. Section 303A.10 of the NYSE Listed Company Manual requires that a listed company’s code of business conduct and ethics mandate that any waiver of the code for executive officers or directors may be made only by the board or a board committee and must be promptly disclosed to shareholders. The Code of Conduct, as described on page 41, complies with Canadian Rules. Waivers must receive prior approval by the board and will be disclosed promptly in accordance with applicable securities laws and Algonquin’s disclosure policy. Section 303A.14 of the NYSE Listed Company Manual requires that a listed company adopt and comply with a written recovery policy providing that the listed company will recover reasonably promptly the amount of erroneously awarded incentive-based compensation in the event that the listed company is required to prepare an accounting restatement due to the material noncompliance of the listed company with any financial reporting requirement under the securities laws, including any required accounting restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. While the Canadian Rules do not require that an issuer adopt a written recovery policy, Algonquin has adopted a compensation clawback policy that complies with Section 303A.14 of the NYSE Listed Company Manual. Algonquin’s compensation clawback policy also provides that where a senior executive was engaged in conduct determined to be misconduct (as defined in the policy), or clawback is required under applicable law, rule, or regulation or by a regulatory body, the HRCC has the discretion to recoup amounts paid or awarded to any executive officer as performance-based compensation or to cancel any performance-based compensation awards made to any executive officer within the three preceding years. Section 312 of the NYSE Listed Company Manual requires that a listed company obtain shareholder approval prior to the issuance of securities in connection with, among other things, the establishment or amendment of certain equity compensation plans, issuances of securities to related parties, the issuance of 20% or greater of shares outstanding or voting power, and issuances that will result in a change in control. Algonquin follows the Canadian Rules for shareholder approval of new issuances of its Common Shares instead of the NYSE shareholder approval rules. Following the Canadian Rules, shareholder approval is required for certain issuances of shares that: (i) materially affect control of Algonquin; or (ii) provide consideration to insiders in aggregate of 10% or greater of the market capitalization of Algonquin and have not been negotiated at arm’s length. Shareholder approval is also required, pursuant to the Canadian Rules, in the case of private placements: (x) for an aggregate number of listed securities issuable greater than 25% of the number of securities of the listed issuer which are outstanding, on a non-diluted basis, prior to the date of closing of the transaction if the price per security is less than the market price; or (y) that during any six-month period are to insiders for listed securities or Options, rights, or other entitlements to listed securities greater than 10% of the number of securities of Algonquin which are outstanding, on a non-diluted basis, prior to the date of the closing of the first private placement to an insider during the six-month period. In addition to the foregoing, the Corporation may from time-to-time seek relief from the NYSE corporate governance requirements on specific transactions under the NYSE Listed Company Guide, in which case the Corporation expects to make the disclosure of such transactions available on the Corporation’s website.

Chande ALGONQUIN | LIBERTY 38 Continuing education for directors The board and management believe that for directors to be effective, they must be knowledgeable about the Corporation, its strengths and challenges, and the industry and business environment in which the Corporation operates. Directors are encouraged to update, educate, and inform themselves in areas they request or that management believes are relevant to issues facing the Corporation. Directors receive briefing reports and materials from management in advance of all meetings. Regular communication is also provided to directors between meetings to facilitate updates on material developments that may affect the Corporation or its businesses. Directors are encouraged to participate in external education sessions that are related to the business of the Corporation or the performance of their duties as directors. The Corporation maintains a membership for all directors in the Canadian Institute of Corporate Directors (“ICD”) and the National Association of Corporate Directors (“NACD”) in the U.S. These memberships provide all directors with ongoing access to the educational seminars and training programs provided by the ICD and the NACD. Directors are entitled to reimbursement for out-of-pocket expenses incurred in attending relevant education sessions. From time to time, the board receives specialized presentations from external parties and/or management on various matters of significance to the Corporation. Directors participated in education sessions in 2023 as follows:

2024 Management Information Circular 41 Corporate and board policies Code of Business Conduct and Ethics The board has adopted the Code of Conduct that applies to everyone at Algonquin and its subsidiaries. Directors, officers, and employees are required to annually acknowledge through an online training module or in writing that they have reviewed and understood the Code of Conduct. The Code of Conduct is available on Algonquin’s website at www.algonquinpower.com, under the Corporation’s profile at www.sedarplus.ca, or a copy may be obtained by contacting the Corporate Secretary, Algonquin Power & Utilities Corp., 354 Davis Road, Suite 100, Oakville, Ontario, Canada L6J 2X1. The board regularly reviews the Code of Conduct and approves revisions as appropriate to update the content in keeping with best practices. The board and its committees monitor compliance with the Code of Conduct through ongoing reporting by management, any whistleblower complaints or investigations, and through the annual Code of Conduct training and certification process. There have been no instances of any waiver of compliance with the Code of Conduct by any director or officer. Disclosure policy The Corporation has a disclosure policy to promote timely, factual, and accurate communications to the market and to require information to be disseminated in accordance with all applicable legal and regulatory requirements. Ethics reporting policy The Corporation has an ethics reporting policy (“Ethics Policy”) that establishes a method for dealing appropriately with any complaints relating to, among other matters, irregular or dishonest accounting, internal accounting controls, auditing matters, or fraudulent or illegal activity by any employee, contractor, officer, or director. Any individual who in good faith reports such activity will be protected from retaliation as a result of the report. Any individual who retaliates against another individual who reports such activity could face disciplinary action under the Ethics Policy. If an individual believes that retaliation has occurred, the individual may submit a complaint in accordance with the Ethics Policy. There are various communication channels that can be used to report any potential or suspected violations of the Code of Conduct, dishonest accounting, internal accounting controls, auditing matters, or fraudulent or illegal activity. In addition to the reporting measures mentioned above, reports under the Code of Conduct can also be made anonymously and addressed to the Corporation or the board. On a quarterly basis, or more frequently upon request, the Compliance and Ethics function informs the Risk Committee of all reports made under the Code of Conduct and the Ethics Policy and their status. The Compliance and Ethics function also informs other standing committees of the board, if applicable based on the subject matter of the report. Insider trading policy The Corporation has an insider trading policy (“Insider Trading Policy”) that places restrictions on those in a special relationship with Algonquin (including insiders) when trading securities of Algonquin. The Insider Trading Policy includes the following measures: Restriction from trading securities of Algonquin during regular trading blackout periods when financial results are being prepared and have not yet been publicly disclosed. These periods currently begin on the first trading day following each fiscal quarter and end at the close of trading on the first full trading day after the issuance of a press release in respect of Algonquin’s results for such quarter (or in the case of the fourth quarter, annual results); Restrictions on trading any securities which gain in value if the value of Algonquin securities declines in the future; and Prohibition from communicating inside information to others, other than in the necessary course of business. The Insider Trading Policy also provides that all directors, officers, and employees are prohibited from, directly or indirectly, undertaking any of the following activities: Speculating in securities of the Corporation, which may include buying with the intention of quickly reselling such securities, or selling securities of the Corporation with the intention of quickly buying such securities (other than in connection with the acquisition and sale of securities under the Option Plan or any other Algonquin benefit plan or arrangement);

ALGONQUIN | LIBERTY 42 Buying Algonquin securities on margin (other than in connection with the acquisition and sale of securities under the Option Plan or any other Algonquin benefit plan or arrangement); Short selling a security of the Corporation or any other arrangement that results in a gain only if the value of the Corporation’s securities declines in the future; Selling a “call option” giving the holder an option to purchase securities of the Corporation; Buying a “put option” giving the holder an option to sell securities of the Corporation; and Pledging Algonquin securities as security for a limited recourse or non-recourse loan. All reporting insiders are required to: (i) obtain written pre-clearance of any proposed trade of securities of Algonquin from two Insider Trading Policy Administrators before effecting the trade, at least one of whom must be the Board Chair or the Chair of the Audit & Finance Committee; and (ii) disclose all trading activity pursuant to Canadian securities laws. As required by Canadian securities laws, reporting insiders must file insider reports via the internet-based System for Electronic Disclosure by Insiders. Management regularly reviews the Insider Trading Policy to reflect current best practices and legal developments. Conflicts of interest Directors are required to declare any conflict of interest which they may have in a matter before the board and to refrain from voting in respect of the matter in which the director is interested. Related party transactions policy The board has adopted a related party transactions policy. The policy defines a “Related Party Transaction” as a transaction, arrangement, or relationship in which the Corporation or any of its subsidiaries is a party and the amount of the transaction when aggregated with all similar transactions exceeds $nil and in which a Related Party has a direct or indirect material interest. A “Related Party” is defined as: Any person who is, or at any time since the beginning of the Corporation’s last fiscal year was, a director or executive officer of the Corporation. An executive officer of the Corporation is someone responsible for achieving the objectives of the entity and who has the authority to establish policies and make decisions by which those objectives are to be pursued. Executive officers normally include the chief executive officer, chief operating officer, presidents in charge of principal business functions (such as sales, administration, or finance), and other persons who perform similar policy making functions; Any shareholder who beneficially owns in excess of 5% of the outstanding common stock or voting interests of the Corporation or any subsidiary of the Corporation; A person who is an immediate family member of any director or executive officer (which means any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, sister-in-law, and any person other than a tenant or employee sharing the house of such director or executive officer); Any firm, corporation, charitable organization, or other entity in which any of these persons is employed or an officer, general partner, principal, or in a similar position or in which any such person, taken together with all parties related to such person, has a beneficial ownership interest of 10% or more or can significantly influence the management or operating policies of the other party to an extent that one of the transacting parties might be prevented from fully pursuing its own separate interests; and Any trusts for the benefit of employees, such as pension and profit-sharing trusts that are managed by, or under the trusteeship, of management. Pursuant to the policy, all Related Party Transactions require review by the disinterested members of the board who must be satisfied that the transaction is on terms and conditions that are in, or are not inconsistent with, the best interests of the Corporation and the Shareholders. In circumstances where it is not practical to wait until the next meeting of the board, the policy authorizes the Board Chair to review and approve a Related Party Transaction unless the Board Chair is a Related Party in the Related Party Transaction.

Compensation decision-making process The HRCC reviews the amount and form of non-employee directors’ compensation with a view to aligning the interests of directors and Shareholders and providing market-competitive compensation. Any changes to non-employee directors’ compensation are approved by the Board following the HRCC’s recommendation. The HRCC works with its independent compensation advisor to develop appropriate benchmark data to align the compensation paid to non-employee directors with the market median level of compensation earned by directors at comparable companies in the U.S. The same U.S. benchmarking peer group is utilized for director compensation and executive compensation (see “Compensation Comparator Group” starting on page 52). The market median of the U.S. benchmarking peer group is used because the majority of the Corporation’s business is based in the U.S. and the board seeks to attract and retain directors with industry and market experience in that jurisdiction. The HRCC also takes into account director remuneration levels at public companies in Canada that are listed on the TSX. As part of its review, in addition to competitive market data, the HRCC considers the responsibilities and time commitment required of directors in the fulfillment of their responsibilities. A significant portion of non-employee director compensation is paid in the form of DSUs granted under the DSU Plan. This approach creates alignment with the long-term interests of Shareholders as the value of one DSU is equal to the value of one Common Share and directors cannot redeem DSUs until after they have left the board. Directors may elect annually to receive additional portions of their annual remuneration in DSUs rather than cash. For 2023, Mr. Goldberg and Ms. Samil elected to receive 33% and 15%, respectively, of the cash portions of their retainers in the form of additional DSUs. 2024 Management Information Circular 43 Non-employee director compensation While the Option Plan permits the issuance of Options to directors, no director holds any Options and there are no plans to utilize Options as a form of non-employee director compensation in the future. No changes were made to the amounts of non-employee director compensation in 2023. The Board Chair received an “all-in” retainer with no payment of additional fees, except for travel fees and fees for membership on special committees of the board, if applicable. All other non-employee directors received an annual retainer, meeting fees, and travel fees. A meeting fee of US$1,500 was payable (except to the Board Chair) for attendance at meetings of the board and its committees and other board-related events or activities, such as educational seminars. For 2023, the board approved a cap on meeting fees for attending board meetings equal to US$22,500, which was equivalent to 15 meetings. Accordingly, directors did not receive meeting fees for the last two board meetings held in 2023. A travel fee of US$1,500 was payable for travel exceeding 1,000 km on a roundtrip basis to such meetings, events, or activities. Directors are also entitled to be reimbursed for their reasonable out-of-pocket expenses incurred in connection with the conduct of the Corporation’s business. The board established the Strategic Review Committee on May 2, 2023 to lead the strategic review and identify and assess options for the Corporation’s renewable energy business. The compensation for members of the Strategic Review Committee was aligned with that of the board’s four standing committees; members received a meeting fee of US$1,500 for each meeting and working session attended and received a travel fee of US$1,500 when applicable. The chairs of the Audit Committee, Corporate Governance Committee, HRCC, Risk Committee, and Strategic Review Committee received an additional retainer of US$15,000, US$10,000, US$12,500, US$10,000, and US$15,000, respectively. Mr. Huskilson received no remuneration for serving as a director after August 10, 2023 (i.e., the date on which he was appointed Interim CEO of the Corporation). Mr. Huskilson's compensation for serving as Interim CEO is described under the heading "Interim CEO compensation" on page 48.

The total number of DSUs that can be issued under the DSU Plan as of December 31, 2023 is 181,551 (being 1,000,000 reserved less DSUs outstanding of 724,583 and 93,866 previously vested and settled).

Annual board retainers and fees 2023 retainer/fee Board Chair1 Annual cash retainer Annual equity retainer (DSU value received) US$147,500 US$147,500 Annual board retainer – board members Annual cash retainer Annual equity retainer (DSU value received) US$82,500 US$115,000 Meeting Fee2 US$1,500 Travel Fee3 US$1,500 Additional retainers Chair of the Audit Committee US$15,000 Chair of the Corporate Governance Committee US$10,000 Chair of the HRCC US$12,500 Chair of the Risk Committee US$10,000 Chair of the Strategic Review Committee US$15,000 The Board Chair does not receive any meeting fees for board or standing committee meetings in addition to the annual retainer received, but receives travel fees and meeting fees for participating in meetings of any board special committee of which he is a member. For 2023, fees for attending meetings of the board were capped at US$22,500, or for 15 meetings. Travel fees are payable for any travel exceeding 1,000 km on a roundtrip basis to attend meetings, board-related events, or educational conferences and seminars. The DSU Plan The DSU Plan is intended to promote a greater alignment of long-term interests between non-employee directors and Shareholders. The board utilizes the DSU Plan as part of the Corporation’s overall non-employee director compensation and has adopted a policy of paying a significant portion of the annual board retainer and Board Chair’s retainer in the form of DSUs, which cannot be redeemed by a director until after he or she leaves the board. Since the value of DSUs increases or decreases in lock-step with the price of the Common Shares, DSUs align the long-term interests of directors with those of the Shareholders by tying the realizable value of a significant portion of the directors’ compensation to share price performance. The maximum number of Common Shares that may be issued from treasury under the DSU Plan in settlement of vested DSUs is currently 1,000,000 (which as at December 31, 2023 represented approximately 0.15% of the issued and outstanding Common Shares). At the Meeting, Shareholders will be asked to vote on an amendment to the DSU Plan to increase the maximum number of Common Shares issuable from treasury under the DSU Plan to 2,000,000 (see page 16). As of December 31, 2023, 93,866 Common Shares had been issued from treasury in settlement of vested DSUs, representing 0.01% of the issued and outstanding Common Shares as at that date. As at December 31, 2023, 724,583 additional Common Shares were issuable under outstanding DSU awards, representing 0.11% of the issued and outstanding Common Shares as at that date. A more detailed description of the DSU Plan can be found at Schedule “C”. The table below summarizes certain ratios as at December 31, 2023, 2022, and 2021 regarding the DSU Plan, namely dilution, burn rate, and overhang. Dilution and overhang are measured as a percentage of the total number of Common Shares outstanding as of December 31, 2023, 2022, and 2021 and burn rate is measured using the weighted average number of Common Shares outstanding during the relevant years as noted.

All non-employee directors receive part of their annual retainer in the form of DSUs. A DSU has a value equal to one Common Share. DSUs cannot be redeemed until the director retires, resigns, or otherwise leaves the board. Mr. Moore, as Board Chair, received 50% of his annual retainer in DSUs and all other non-employee Directors received at least US$115,000 of their annual retainers in DSUs. Directors may elect each year to receive more than the mandated amount of their compensation in the form DSUs. The amounts for Mr. Huskilson show the compensation he received for serving as a non-employee director from January 1 to August 9, 2023, including serving as Chair of the Risk Committee from June 20 to August 9, 2023 and Chair of the Strategic Review Committee from May 2 to August 9, 2023. Mr. Huskilson's compensation for serving as Interim CEO beginning on August 10, 2023 is described under the heading "Interim CEO compensation" on page 48.

ALGONQUIN | LIBERTY 46 Executive compensation HRCC’s Letter to Shareholders Dear Shareholder, One of the HRCC’s primary responsibilities is to reinforce Algonquin’s pay for performance philosophy and culture. This responsibility has been particularly important over the last two annual compensation cycles, a period during which the Corporation’s overall financial performance and total shareholder return (“TSR”) have been below our expectations. Disappointingly, the Corporation’s earnings and returns have not recovered to their pre-2023 levels despite decisive actions to advance the Corporation’s strategy and significant management achievements to position the businesses to deliver shareholder value. It was within this context that the HRCC took advice from its independent compensation advisor, assessed a range of compensation outcomes for executives, and made recommendations to the board. The executive compensation decisions approved by the board and described in the pages that follow resulted in the total direct compensation realized or realizable in 2023 by our NEOs who were in their roles for the full year and who had PSUs that vested in 2023 (i.e., Messrs. Johnston and Norman and Ms. Tindale) being on average 51.2% of their pay reported in the Summary Compensation Table (see page 75) and their total direct compensation realized or realizable in 2023 being on average 59.8% of their target total direct compensation (see page 49). The HRCC believes that the executive compensation decisions approved by the board appropriately balanced the experience of our shareholders with the important contributions made by management to Algonquin’s future success and shareholder value creation. This letter summarizes the HRCC’s approach to executive compensation and other key initiatives in 2023 and highlights our priorities for 2024. We trust that the information that follows, including the compensation discussion and analysis, will provide you with the information necessary to make an informed decision as you cast your vote on our approach to executive compensation at the meeting on June 4, 2024.

2024 Management Information Circular 47 2023 highlights and pay decisions Despite disappointing TSR and overall financial results, in 2023 the Corporation made significant progress on several key strategic and business initiatives to strengthen our foundations for future performance. The board completed a thorough strategic review of the Corporation’s renewable energy business and determined that the best path forward to unlock shareholder value is to transition to a “pure play” regulated utility business. This transition will enable us to focus on lower risk regulated investment opportunities with greater operational efficiency and capital discipline. In November, the Corporation announced the launch of a process to sell the renewable energy business. .• The Corporation successfully finalized several rate cases in the regulated business, including at our electric utilities in Missouri, California, New Hampshire, and Bermuda and our water utilities in California. The implementation of rate increases following these cases contributed significantly to the revenues and overall financial performance of the regulated business. The Corporation achieved commercial operations at the 112 megawatt Deerfield II wind facility in Michigan, the 88 megawatt Sandy Ridge II wind facility in Pennsylvania, the 108 megawatt Shady Oaks II wind facility in Illinois, the 95 megawatt New Market solar facility in Ohio, and the 25 megawatt Hayhurst solar facility in New Mexico. The Corporation’s ESG rating was upgraded to “AAA” by MCSI Inc., placing Algonquin among the top 13% of all companies rated. The Corporation sustained its industry top-decile safety performance with a total recordable incident rate of 0.73. The Corporation ended 2023 with only one lost-time injury during the year. The Corporation mutually agreed with American Electric Power Company, Inc. to terminate the agreement relating to the acquisition of Kentucky Power Company and AEP Kentucky Transmission Company, Inc. The termination allowed for the reallocation of approximately US$1 billion towards other essential capital investments. These financial and non-financial accomplishments were reflected in the 2023 Corporate Scorecard result, which was calculated at 86.3% of target (see “Short-term incentive plan” beginning on page 56 for additional details). The 2021 PSU awards vested at 28.8% of their original grant date value, based on the closing price of the Common Shares on the TSX on December 29, 2023 of $8.36. The number of PSUs that vested was 61.0% of the original grant (excluding accrued dividend equivalent units) based on the performance factor achieved. (See “2021 PSU award performance results” beginning on page 63 for additional details.)

Contemporaneously with the strategic review of the renewable energy business, the HRCC considered the Corporation’s recent performance and future strategy and recommended to the board a CEO transition. As part of this transition, Christopher Huskilson was appointed as Interim CEO effective August 10, 2023. Mr. Huskilson brings extensive industry experience and a strong track record to the role, given his long and successful tenure as the chief executive officer of Emera, Inc. Mr. Huskilson also has in-depth knowledge of the Corporation’s businesses and assets, having served as a director since 2020 and from 2009 to 2016. Since Mr. Huskilson’s appointment as Interim CEO, the HRCC has focused on optimizing the Executive Team’s structure, roles, and responsibilities while progressing the search for a long-term CEO candidate to lead the Corporation into the next stage of its growth as a “pure play” regulated utility business. The HRCC has engaged an independent consultant to support the search through the identification and vetting of candidates with the desired attributes and experience. At the request of the HRCC, Dilek Samil, the HRCC’s prior chair, is participating in the CEO search process. The HRCC’s other significant initiatives in 2023 included a review of external compensation trends, a refresh of the Corporation’s compensation peer groups (see page 52), a compensation risk assessment, approval of an updated compensation clawback policy (see page 70), and the implementation of a retention program for certain employees working in or supporting the renewable energy business to preserve the value of the business while the sale process is in progress. Interim CEO compensation The HRCC recommended that Mr. Huskilson’s compensation as Interim CEO should be paid entirely in the form of RSUs. Mr. Huskilson receives a grant of RSUs on the first business day of each month. The annualized value of the RSUs payable to Mr. Huskilson is $5,500,000, which is equal to the total target direct compensation of the former CEO. The RSUs are fully vested on the grant date and may be redeemed for Common Shares at Mr. Huskilson’s election at least two years after the grant date. Mr. Huskilson is not eligible to participate in any other salary, incentive, benefit, or perquisite program offered by the Corporation while he serves as Interim CEO. The HRCC believes that the value of Mr. Huskilson’s compensation as Interim CEO appropriately reflects the knowledge, skill, and experience that he brings to the role, and that payment in the form of RSUs that cannot be redeemed for at least two years creates strong alignment with shareholders’ interests. Executive compensation components and pay mix Total target direct compensation for executives (other than the Interim CEO) consists of base salary, short-term incentive, and long-term incentive. Each of these components is described in more detail in the disclosure that follows this letter. The HRCC believes that compensation should be strongly aligned to performance and the compensation mix for executives reflects this through a significant portion of pay-at-risk. Pay-at-risk is compensation that varies based on performance and/or with the value of the Common Shares. For 2023, the target compensation mix for the NEOs other than the Interim CEO ranged from 67% to 73% at risk. The Interim CEO’s compensation is 100% at risk.

2024 Management Information Circular 49 On behalf of the HRCC, Melissa Stapleton Barnes (Chair) 2023 realized and realizable compensation The HRCC carefully assessed the realized and realizable value of executive compensation in 2023. As shown in the table below, the realized and realizable total direct compensation for the NEOs who held their executive roles with the Corporation during all of 2023 and who had PSUs that vested in 2023 was on average 59.8% of their targets. These compensation values reflect the Corporation’s financial performance and the experience of Shareholders in 2023 and demonstrates the alignment of pay with performance.

Option Value Vested is the in-the-money value as of December 31, 2023 of options that vested during the year. 2024 outlook The HRCC's top priority for 2024 is continued succession planning, including creating the conditions for an effective and efficient leadership transition. The HRCC is grateful for Mr. Huskilson’s leadership, stewardship, and guidance during this time, and his continued service as a director following the appointment of a long-term CEO will no doubt help position the successful candidate, and the Corporation, for future success. The HRCC will also oversee a comprehensive review of the Corporation’s incentive plans in 2024. An objective of the review will be to simplify the performance metrics that have been used historically in the Corporate Scorecard and those used to determine the vesting of PSUs. The HRCC believes that simplification will improve transparency for both employees and shareholders and strengthen the Corporation’s pay for performance philosophy. The initial stages of this review have already been completed; the number of performance metrics comprising the 2024 Corporate Scorecard has been reduced from 16 to seven compared to 2023 and the board has recommended that shareholders approve amendments to the Share Unit Plan described in this circular (see “Amendments to the Share Unit Plan” on page 13) to better align with market practices. Details on the 2024 Corporate Scorecard and PSU grants will be included in the Corporation’s 2025 management information circular.

50 ALGONQUIN | LIBERTY Compensation highlights A “pay for performance” philosophy is the foundation of our compensation programs. All members of the HRCC have the knowledge, experience, and background necessary to fulfill their duties. Caps on payouts and vesting conditions are part of overall incentive plan design. A substantial portion of incentives is deferred to discourage executives from taking short-term or excessive risks. Performance-based compensation is subject to our compensation clawback policy. The HRCC and board may exercise discretion when circumstances warrant an outcome different than what incentive plan formulas produced. Equity ownership guidelines are in place for NEOs. Executive employment agreements contain double-trigger provisions in the event of a change of control. An independent consultant is engaged by the HRCC to establish appropriate comparators for compensation and to develop compensation for executives that is competitive in the market. Executive pay is aligned with Shareholder interests by having a significant component at risk and tied to both short- and long-term objectives, including relative total shareholder return performance in the case of PSU awards.

CEO recommendations Management identifies target compensation ranges using peer group and compensation trend information. The CEO makes recommendations regarding executive compensation to the HRCC based on those compensation ranges, internal equity considerations, and performance against objectives. 2024 Management Information Circular 51 HRCC review The HRCC considers these recommendations using benchmark information with the assistance of an independent compensation consultant and other information as required, and makes recommendations to the board. Board approval The directors consider and approve the compensation of the CEO and the other executive officers. Compensation discussion and analysis Annual compensation decision-making process The board has developed a comprehensive annual process for making decisions regarding compensation for the executive officers of the Corporation. This process involves the following steps: The foregoing process is completed within the first quarter of each year. As part of the process, the board, in consultation with the HRCC, also sets the individual and leadership performance objectives for the CEO for the coming year. Performance and leadership objectives for the other executive officers are set by the CEO. For the purposes of determining bonuses under the Corporation’s short-term incentive plan (“STIP”), the board, on the recommendation of the HRCC, annually approves the Corporate Scorecard which sets out objectives against which corporate performance is measured. The Corporate Scorecard results are used in the determination of bonuses for executive officers and other employees in conjunction with performance assessed against individual objectives and, for certain employees below the executive officer level, business unit or divisional objectives. The HRCC works with an independent compensation advisor to monitor the effectiveness of the Corporation’s compensation policies, plans, and programs to enable the Corporation to be competitive and attract, retain, and motivate executives and other employees and reward achievement of the Corporation’s goals. To allow the HRCC and board to establish compensation levels that are appropriate and remain market competitive, the independent consultant conducts a complete benchmarking review every two years. Typically, the review scope includes a review and, if appropriate, amendments to the constituents of the Comparator Group (as defined on page 52), competitive market reviews of executive compensation levels, review and observations of current executive compensation philosophy, policies, and practices, and a review of pay and performance alignment.

Black Hills Corporation Center Point Energy, Inc. Clearway Energy, Inc. CMS Energy Corporation IDACORP, Inc. NiSource Inc. OGE Energy Corp. Pinnacle West Capital Corporation PNM Resources, Inc. Portland General Electric Company The AES Corporation UGI Corporation Compensation Comparator Group To establish appropriate compensation levels relative to the Corporation’s peers, the HRCC worked with its independent compensation advisor to develop a comparator group of Canadian and U.S. organizations primarily engaged in Algonquin’s business sectors (independent power producers and utilities and other sectors of similar complexity) (the “Comparator Group”). The Comparator Group was refreshed in 2023 with the intention that both the Canadian and U.S. groups (described as follows) would consist of an adequate number of peers within a reasonable range of Algonquin’s size. The Comparator Group consists of a Canadian-based peer group and a U.S.-based peer group with the intention that the Canadian peer group (the “Canadian Comparator Group”) be the primary benchmarking group for executives, with the U.S. peer group (the “U.S. Comparator Group”) being referenced in situations where the location of an executive’s work or the talent pool for recruiting for a role is primarily the U.S. market. The Canadian Comparator Group was developed by considering general industry peers having a similar total enterprise value, asset size, revenues, and business model to the Corporation. The lack of sufficient direct industry peers in Canada of similar size required broader selection criteria to develop an appropriate peer group. The U.S. Comparator Group was developed from close industry peers selected based on similar operations and with similar total enterprise value, asset size, and revenues. The Canadian Comparator Group consists of 11 companies with a median total enterprise value of $25.3 billion, median total asset value of $24.0 billion, and median revenues of $7.2 billion. The U.S. Comparator Group consists of 15 companies with a median total enterprise value of $25.3 billion, median total asset value of $27.3 billion, and median revenues of $6.1 billion. The market benchmarking for the Corporation’s compensation structure is based on compensation data from the Comparator Group. Comparator Group enterprise value, assets, and revenues are as of July 14, 2023. The Comparator Group for 2023 consists of the following entities: While the intention is to use a consistent list of comparators from year to year, the comparators used for compensation review are subject to periodic change due to the availability of relevant pay data, mergers and acquisitions, and relevance of new comparators based on updated financial metrics.

2024 Management Information Circular 53 Fees paid to compensation consultants The fees paid by the Corporation to compensation advisors for the work performed in the last two years are as follows: Advisor 2023 Executive compensation-related fees All other fees1 2022 Executive compensation-related fees All other fees1 Hugessen Consulting Inc. $381,547 - $83,696 - Mercer (Canada) Limited - $162,101 - $194,776 1. All other fees are fees for work undertaken by the advisor for management relating to the collection of market data or database access, benchmarking, pension investment counsel or benefits advice, including due diligence services relating to employee pension and benefits in relation to potential acquisitions, and integration work for employee benefits plans for acquired businesses. Risk management and compensation The board has implemented compensation policies and practices to mitigate the risk of executives and employees taking inappropriate or excessive risks. These policies and practices include: STIP payouts are capped at 200% of target awards; A cap on the maximum performance factor under the Share Unit Plan which limits the number of PSUs that can vest to 237% of the number initially granted; Termination and severance provisions with double triggers in the event of a change in control; A compensation clawback policy; Inclusion of non-financial performance measures in incentive compensation plans; and Board discretion to amend the final payouts under the incentive compensation programs. As part of the HRCC’s oversight responsibilities for the design and administration of the Corporation’s executive compensation programs, the HRCC identifies and discusses plan design features or processes that may potentially represent conflicts of interest and/or inducements for inappropriate or excessive risk-taking by senior management. The HRCC also satisfies itself as to the adequacy of the information it receives, the independence of the review, and reporting of financial results on which important compensation decisions (e.g., the amount of annual incentives to be paid) are based. These existing safeguards notwithstanding, the HRCC periodically reviews the relationship between enterprise risk and the Corporation’s executive compensation plans and policies to confirm that they continue to be aligned with Shareholder interests while maintaining an acceptable level of risk exposure. The HRCC’s independent compensation advisor reviews the potential risks associated with the Corporation’s compensation programs and policies. These reviews include an assessment of each of the Corporation’s incentive compensation programs individually, as well as holistically, to identify any risks inherent in the design or application of the programs. The HRCC most recently engaged its independent advisor, Hugessen, to perform a risk assessment of the Corporation’s executive compensation plans in 2023. Hugessen’s assessment report did not identify any material risks arising from the Corporation’s executive compensation plans. Based upon its ongoing reviews and the independent assessment referred to above, the HRCC has concluded that the Corporation’s executive compensation programs do not create inordinate risk for the Shareholders because an appropriate system of checks and balances is in place. When material changes are proposed to existing compensation plans or new plans are developed, it is the HRCC’s practice to engage its independent advisor to review the potential changes as well as any differences in risk profile.

ALGONQUIN | LIBERTY 54 Named Executive Officer compensation This section discusses the elements of compensation for the NEOs in 2023, namely: Christopher Huskilson, Interim Chief Executive Officer (“Interim CEO”); Darren Myers, Chief Financial Officer (“CFO”); Johnny Johnston, Chief Operating Officer (“COO”); Jeff Norman, Chief Development Officer (“CDO”); Jennifer Tindale, Chief Legal Officer (“CLO”); and Arun Banskota Former Chief Executive Officer (“Former CEO”). Executive compensation philosophy The mandate of the HRCC includes the review of the Corporation’s executive compensation philosophy. The Corporation’s executive compensation philosophy is based on pay-for-performance and is designed to attract, motivate, and retain executives, reward them for the Corporation’s financial and operational performance and individual contributions, and facilitate smooth succession processes. When determining compensation policies and individual compensation levels for the Corporation’s executive officers (other than the Interim CEO), the HRCC and board have adopted the following approach: Executive compensation is set with reference to the Canadian Comparator Group. The U.S. Comparator Group is considered as a secondary reference. In appropriate circumstances, the weighting of the Canadian Comparator Group and U.S. Comparator Group may change depending on executive job location, executive responsibilities, local pay practices, and internal equity. Pay is benchmarked and compared on a total target direct compensation basis (i.e., base salary + target annual short-term incentive + target annual long-term incentive). Benefits, perquisites, and pensions are considered separately and established based upon market data for the market in which the executive is employed. Given that the Corporation holds long-term assets and management decisions in any given year can have long-term implications, overall compensation is designed so that a majority of total target direct compensation is delivered through variable pay-at-risk and longer-term compensation elements. Compensation levels, mix, and incentive plans are designed so that total target direct compensation is positioned at the median of the relevant Comparator Group. Variable compensation is designed so that compensation is at the median level for target performance, above median for above-target performance, and below median for below-target performance.

Judgment is applied and discretionary adjustments are made when appropriate to avoid an entirely mechanical process for setting each position’s pay and to strengthen pay-for-performance alignment. The Interim CEO’s compensation was set at an amount equal to the total target direct compensation of the Former CEO and is paid entirely in the form of RSUs that are fully vested on the grant date, but which cannot be redeemed for Common Shares for at least two years after the grant date. The HRCC and board believe that this compensation structure appropriately reflects the short-term nature of the Interim CEO’s appointment while creating strong alignment with the long-term interests of Shareholders. Compensation mix The Corporation’s compensation program is based on concepts of pay-for-performance, market competitiveness, and internal equity, taking into account the roles and responsibilities of each level of employment in the organization. The program is designed to attract, retain, and motivate strong talent in a competitive business environment, to reward participants when corporate and personal objectives are achieved, and to promote a high-performance culture. In keeping with the Corporation’s philosophy to link executive compensation to corporate performance, the Corporation’s compensation model includes both base salary and at-risk compensation. At-risk compensation consists of short-term incentives and long-term incentives, both of which are subject to the achievement of performance objectives and, in the case of long-term incentives, Share price appreciation and Shareholder returns. The at-risk component of short-term incentives for executives (other than the Interim CEO) depends on the achievement of annual corporate objectives and individual objectives and leadership performance. These objectives establish financial, operational, stakeholder, sustainability, and individual goals that, if achieved, add value to the Corporation. Incentive compensation plans are designed to pay larger amounts for superior performance and lower amounts if target performance is not achieved. Total target direct compensation consists of base salary, target short-term incentive, and target long-term incentive. In setting the total target direct compensation for the NEOs (other than the Interim CEO), the HRCC and board take into consideration the advice and recommendations provided by the HRCC’s independent compensation advisor which are based on the compensation earned by similar executive officers in the relevant Comparator Group (see discussion on page 52 under the heading “Compensation Comparator Group”). The following table shows the dollar value and percentage weighting of each component of the total target direct compensation for the NEOs (other than the Interim CEO) in 2023.

ALGONQUIN | LIBERTY 56 Base salary Base salaries of the NEOs (other than the Interim CEO) are established at levels which are meant to be competitive with other organizations with similar scope of operations, and of comparable size, to the Corporation. Base salaries are not a function of any specific relationship to the performance of the Corporation and are reviewed annually by the HRCC. The board approves any changes to the base salaries of the NEOs based on the recommendations of the HRCC. The HRCC’s recommendations are established through benchmarking relative to the Comparator Group by the HRCC’s independent compensation advisor. Short-term incentive plan The STIP is an annual cash bonus plan, the purpose of which is to align compensation with business results and individual performance, thereby promoting behaviours that benefit the Corporation and its Shareholders. Target STIP awards are based on position and market competitiveness and STIP payouts are capped at 200% of the target award. Short-term incentives are calculated and paid annually based on achievement relative to scorecard goals and objectives as well as individual performance, as described below. Each NEO (other than the Interim CEO) is eligible for an award under the STIP if established corporate and personal goals and objectives are achieved. Each year, the corporate goals and objectives (the “Corporate Scorecard”) are reviewed and approved by the board on the recommendation of the HRCC. Personal goals and objectives for the NEOs (other than the Interim CEO) are determined by the CEO and are aligned with the Corporate Scorecard for that year. The amount of the annual STIP award is determined by the aggregate STIP score (“STIP Factor”) achieved by an NEO. The STIP Factor is calculated for each NEO with 80% weighting assigned to results achieved under the Corporate Scorecard and 20% weighting assigned to individual objectives and leadership performance. The formula for calculating the STIP Factor is set out on page 57. The board established priorities for the Interim CEO in connection with his appointment on August 10, 2023, but the Interim CEO is not eligible for an award under the STIP or any other short-term incentive plan offered by the Corporation.

STIP payouts Annual STIP payouts for the NEOs (other than the Interim CEO) are calculated as follows: The STIP Factor is calculated as follows: STIP Factor Corporate Scorecard weight Leadership objective weight Base salary Target % STIP payout STIP Factor In 2023, the HRCC and board implemented a new feature in the STIP that would limit STIP payouts to executives if a certain financial performance target was not achieved. Specifically, if the Corporation did not generate at least 85% of the target amount of adjusted earnings before interest and taxes (“EBIT”)1, then for the purposes of calculating the Corporate Scorecard result for executives, all performance metrics would be assessed at the lower of their target or the actual performance achieved. 2024 Management Information Circular 57 Corporate Scorecard achievement Leadership objective achievement 1. For additional information on this non-GAAP measure, please see “Caution concerning non-GAAP financial measures” on page 6. 2023 Corporate Scorecard results The 2023 Corporate Scorecard contained 16 objectives that were grouped into two categories weighted as follows: (i) four financial metrics with an aggregate weighting of 60%; and (ii) 12 non-financial metrics with an aggregate weighting of 40%. The HRCC assessed the Corporation’s performance in 2023 on each of the objectives and determined that the overall Corporate Scorecard result for the year was 86.3% of target. The performance assessment for each objective is shown on the following pages. The actual 2023 STIP awards to the NEOs are described under “2023 executive performance highlights” beginning on page 73 and in the Summary Compensation Table on page 75.

Corporate Scorecard results The following sets out the 2023 Corporate Scorecard objectives and performance results achieved relative to those objectives. Targets and results noted in the discussion below are established and measured based on an exchange rate of $1.25/US$1.00, the 2023 budget rate. Accordingly, reported performance may vary from results in the financial statements of the Corporation for 2023 due to difference in exchange rates used. The overall 2023 Corporate Scorecard result was 86.3 points out of a target of 100 and a maximum of 200. In the financial metrics category, the Corporation achieved a score of 34.5 points out of a target of 60 and a maximum of 120. The result was driven primarily by below threshold performance on the earnings per share metric and below target performance on the EBIT and FFO/Debt ratio metrics. The score in the non-financial metrics category was 51.8 points out of a target of 40 and a maximum of 80. The Corporation exceeded target on several non-financial metrics, including safety, environmental, social, and governance factors, and three of four metrics relating to system reliability, but was below threshold performance on customer satisfaction. The Corporation achieved 98.5% of the 2023 EBIT target, therefore the potential limit on STIP payouts to executives described on page 57 did not apply.

The Black-Scholes value for the 2023 Option grants was determined using the following assumptions: The safe harbour term used is equal to ((time to expiry + 3) / 2). Option term is eight years. The volatility of the share price is based on the average daily volatility over the last 750 trading days (three years). The risk-free rate is equal to the yield of a Government of Canada bond with same term as the expected life of the Option. Grant date March 27, 2023 Term1 5.5 years Volatility2 30.3% Dividend yield 6.8% Risk-free rate3 2.7% ALGONQUIN | LIBERTY 60 The long-term incentive plan The long-term incentive plan (“LTIP”) element of compensation for the NEOs (other than the Interim CEO) consists of participation in the Option Plan and the Share Unit Plan. The Interim CEO’s compensation is entirely in the form of RSUs granted under the Share Unit Plan. The LTIP is intended to incentivize and reward behaviour that creates long-term value for Shareholders by aligning the interests of executives with long-term Shareholder interests. To achieve this, the future value of the LTIP awards is tied to the value of the Common Shares. The realization of such value depends on the achievement of performance-vesting criteria and share price growth, which creates a strong link to long-term performance. The numbers of Options and PSUs granted to the NEOs (other than the Interim CEO) as annual long-term compensation awards are determined by the board on the recommendation of the HRCC and are based on the percentage of their total target direct compensation to be granted in the form of long-term incentives. Previous grants of Options and PSUs are not considered when approving new grants, as annual grants are made based on the long-term incentive target. For each NEO (other than the Interim CEO), the 2023 target long-term incentive award was granted 25% as Options and 75% as PSUs. Options have value only if the market price of Common Shares exceeds the price at which the Options were granted. PSUs increase or decrease in value in proportion to the increase or decrease in the market price of the Common Shares over the term of a particular grant. The fair value of Option grants is based on the greater of: (i) the value determined by using the Black-Scholes valuation methodology, as it is an appropriate and commonly used methodology to value Options; or (ii) a value equal to 10% of the price of Common Shares on the TSX at the date of grant. For the Options granted in 2023, the Black-Scholes value was determined to be equal to 13.9% of the grant price of $10.76.

The time-weighting factor is the number of days that the securities are outstanding as a proportion of the total number of days in the period. The weighted average number of securities outstanding is calculated in accordance with the CPA Canada Handbook and as such may be amended or superseded from time to time. The total number of Options granted in each year was as follows: 2023 – 1,368,744; 2022 – 646,090; and 2021 – 437,006. The total number of Common Shares that can be issued under the Option Plan as of December 31, 2023 was 41,934,707. 2024 Management Information Circular 61 The Option Plan The purpose of the Option Plan is to attract, retain, and motivate executives and to align the interests of executives with Shareholders by providing executives with the opportunity, through Options, to build their equity interests in the Corporation. The Option Plan authorizes the board to issue Options to directors, officers, employees, consultants, or other service providers of Algonquin or any of its subsidiaries (“Eligible Persons”). There are no plans to issue Options to directors or to any Eligible Person other than the Corporation’s executive officers. Options are granted to executives each March as part of the Corporation’s annual compensation cycle. The Options have a term of eight years. They vest in three equal tranches commencing on December 31 of the year of grant and on December 31 of the two subsequent years. The aggregate number of Common Shares that may be reserved for issuance from treasury on the exercise of Options under the Option Plan, together with the Common Shares issuable from treasury under grants under all other securities-based compensation arrangements of the Corporation, must not exceed 8% of the number of Common Shares issued and outstanding at the time the Options are granted. The Option Plan is “reloading,” meaning that to the extent Options expire or are terminated, cancelled, or exercised, the Corporation may make a further grant of Options in replacement for such expired, terminated, cancelled, or exercised Options, provided that the 8% maximum is not exceeded. No fractional Common Shares may be purchased or issued under the Option Plan. As of December 31, 2023 the number of outstanding Options was 2,667,725 which represented 0.39% of the total issued and outstanding Common Shares as at that date. The number of available Options as of December 31, 2023 was 41,934,707, which represented 6.08% of the total issued and outstanding Common Shares as at that date and is equal to 8% of the total issued and outstanding Common Shares as at that date, less those Common Shares issuable from treasury under all other securities-based compensation plans and Options outstanding on that date. The number of Common Shares that have been issued pursuant to the Option Plan as of December 31, 2023 was 6,945,565. The number of Common Shares that have been issued pursuant to the Option Plan as a percentage of the issued and outstanding Common Shares as at December 31, 2023 was 1.01%. A more detailed description of the Option Plan can be found at Schedule “E”. The table below summarizes certain ratios as at December 31, 2023, 2022, and 2021 regarding the Option Plan, namely dilution, burn rate, and overhang. Dilution and overhang are measured as a percentage of the total number of Common Shares outstanding as of December 31, 2023, 2022, and 2021, and burn rate is measured using the weighted average number of Common Shares outstanding during the years as noted.

ALGONQUIN | LIBERTY 62 The Share Unit Plan The objectives of the Share Unit Plan are to: (i) align a portion of participating employees’ compensation with the performance of the Corporation over the long-term; and (ii) retain critical employees to drive business success. Under the Share Unit Plan, PSU and RSU awards can be made. Each PSU and RSU awarded represents the opportunity to receive one Common Share (issued from treasury or purchased on the secondary market), or a cash equivalent payment (in either case at the Corporation’s election), at the time of settlement, subject to the satisfaction of performance conditions in the case of PSUs, as described below. PSUs are a component of long-term compensation for employees and vest based on the achievement of performance criteria specified at the time of grant during the three-year performance period commencing on January 1 of the year of grant and ending on December 31 of the third year after the grant. PSU awards make up 75% of the target long-term compensation value for each of the NEOs (other than the Interim CEO who is not eligible for PSU awards). PSUs vest on the last day of the three-year performance period, subject to the degree of achievement relative to the performance criteria. RSUs are issued under the bonus deferral program (see discussion on page 66 under the heading “Bonus deferral program”), for retention purposes, or as sign-on or make-whole compensation to attract senior talent. RSU awards can also be made to facilitate retirement and transition of senior executives on a mutually agreeable timeline and terms. RSU awards are typically time-based awards and vest on continuity of employment or compliance with ongoing contractual obligations during the time specified in the applicable award agreement. RSUs are the sole form of compensation payable to the Interim CEO. The Interim CEO receives a grant of fully vested RSUs on the first business day of each month. The RSUs may be redeemed for an equal number of Common Shares at the Interim CEO’s election at least two years after the date of grant. The annualized value of the RSU grants to which the Interim CEO is entitled is $5,500,000, which is equal to the total target direct compensation of the Former CEO. The maximum number of Common Shares that are issuable from treasury under the Share Unit Plan to settle awards of PSUs and RSUs is currently 7,000,000 (representing approximately 1.02% of the issued and outstanding Common Shares as at December 31, 2023). At the Meeting, Shareholders will be asked to vote on amendments to the Share Unit Plan, including an amendment to increase the maximum number of Common Shares issuable from treasury under the Share Unit Plan to 14,000,000 (see page 13). As at December 31, 2023, 2,826,227 Common Shares have been issued from treasury in settlement of vested PSUs and RSUs, representing 0.41% of the issued and outstanding Common Shares as at that date. As at December 31, 2023, 4,173,773 additional Common Shares were available to be issued from treasury to settle vested PSUs and RSUs issued or to be issued under the Share Unit Plan, representing 0.61% of the issued and outstanding Common Shares as at that date. Grants may be made under the Share Unit Plan to executives or other employees of the Corporation or of any affiliate of the Corporation. For the purposes of the Share Unit Plan, an “affiliate” is any corporation, partnership, or other entity in which the Corporation, directly or indirectly, has majority ownership interest or which the Corporation controls. A more detailed description of the Share Unit Plan can be found at Schedule “A”. PSUs are granted based on a performance period of three calendar years commencing on January 1 of the year in which the PSUs are granted (the “Performance Period”). In addition to the performance criteria specified at the date of grant, a performance modifier is applied to the PSUs based on the cumulative TSR achieved by the Corporation during the Performance Period relative to a group of peers. For PSUs granted in 2021, the Corporation’s cumulative TSR is measured relative to the S&P/TSX Capped Utilities Index. For PSUs granted after 2021, the Corporation’s cumulative TSR is measured relative to a blended average of the S&P/TSX Capped Utilities Index and the S&P 500 Utilities Index, with each group having equal weighting. These peer groups are referred to below as the “Index Group”. If the TSR achieved by the Corporation over the Performance Period relative to the TSR for the Index Group for the same period is between the 25th and the 75th percentile, the number of PSUs that vest will be modified on a pro-rata basis between 80% to 120%. If the TSR performance of the Corporation is at or below the 25th percentile performance of the Index Group, the number of PSUs that vest will be reduced to 80% of those that would have otherwise vested. If the TSR performance of the Corporation is at or above the 75th percentile of the performance of the Index Group, the number of PSUs that vest will increase to 120% of those that would have otherwise vested. In the latter case, there will be no increase applied to the number of PSUs that vest where the Corporation’s TSR performance is negative over the Performance Period despite strong relative performance when compared to the Index Group. If the achievement for any one performance criteria is above target for the Performance Period, the number of PSUs that vest can be increased to a maximum weighting for the relevant performance criteria as follows: (i) efficiency (160%); (ii) safety (20%); and (iii) sustainability (20%). The maximum number of PSUs that can vest under these performance criteria with the TSR modifier applied, assuming maximum relative TSR performance to the Index Group, is 237% of the PSUs originally granted.

Realized value vs. grant date value 28.8% The Sustainability performance factor for the 2021 PSU awards was comprised of nine ESG-related goals as shown on the following page, each weighted at 1.1% of the overall performance factor. Four of the goals were assessed on a numerical scale where additional points were available if performance exceeded the targets. For each of those goals, for every 1% by which performance exceeded the target, 0.00125 additional points were awarded. The remaining five goals were a binary assessment. If the objective was achieved, 0.0111 points were awarded (equivalent to the 1.1% weighting for each goal) and if the objective was not achieved, no points were awarded. The performance factor applied to the 2021 PSU awards was 76.3%. The TSR performance modifier was 80% due to the Corporation’s TSR performance during the Performance Period being below the 25th percentile of the Index Group, producing an overall performance score of 61.0%. Accordingly, the 2021 PSU grants vested at 72.4% of the original number of PSUs awarded when taking into account the overall performance score and additional PSUs granted as dividend equivalents. The realized value of the 2021 PSU grants, based on the December 29, 2023 closing price on the TSX of $8.36 per Common Share, was 28.8% of the original grant date value. The detailed calculation of the performance factor for the 2021 PSU awards is illustrated on page 64. The actual number of PSUs that will vest is determined as follows:

2024 Management Information Circular 65 2023 PSU grants The PSUs granted in 2023 had three performance metrics weighted as follows: (i) efficiency – 80%; (ii) safety – 10%; and (iii) sustainability – 10%. The final score on the efficiency metric will be calculated as the arithmetic average percentage of the number of points achieved in the financial metrics category of the Corporate Scorecard for STIP purposes for each year of the Performance Period. For 2023, 34.5 points were scored in the financial metrics category out of a target of 60, which was equivalent to 57.5%. The average percentage achieved on the efficiency metric for the three years of the Performance Period is used to determine the efficiency factor. Target performance on the efficiency metric is defined as 80% to 120% and produces an efficiency factor of 0.8 (due to the 80% weighting for this metric). Maximum performance on the efficiency metric is 200%, which results in an efficiency factor of 1.6. The final score on the safety metric will be calculated based on the ratio of the average of the actual United States Occupational Safety and Health Administration (“OSHA”) recordable incident rate on a consolidated basis across all businesses in North America operated by Algonquin over the Performance Period divided by the published industry average OSHA Recordable Incident Rate over the same period. The most recent published average will be used for the third year. The ratio achieved is used to determine the safety factor. Target performance on the safety metric is defined as a ratio of between 0.95 and 1.04 and produces a safety factor of 0.1 (due to the 10% weighting for this metric). Maximum performance on the safety metric is a ratio of less than 0.7, which results in a safety factor of 0.2. If the ratio is 1.3 or higher, the safety factor will be 0. For 2023, the Corporation achieved a ratio of 0.43. The sustainability metric will be calculated based on the cumulative placed-in-service renewable energy capacity during the Performance Period. Target performance on the sustainability metric is 990 megawatts and produces a sustainability factor of 0.1 (due to the 10% weighting on this metric). Maximum performance on the sustainability metric is 1,188 megawatts, which results in a sustainability factor of 0.2. If less than 792 megawatts are placed in service, the sustainability factor will be 0. For the purposes of the sustainability metric, “renewable energy capacity” includes both regulated and unregulated wind, solar, hydroelectric, biogas, geothermal, biomass, and battery storage capacity. During 2023, the Corporation placed 434 megawatts of renewable energy capacity into service. The sum of the efficiency factor, safety factor, and sustainability factor at the end of the Performance Period (i.e., December 31, 2025) determines the total performance factor score, with target being 1.0. The performance factor score may be modified positively or negatively by the Corporation’s TSR performance relative to the Index Group over the Performance Period. The combination of the performance factor score and TSR performance determines the percentage of PSUs that vest relative to the number of PSUs originally granted.

The time-weighting factor is the number of days that the securities are outstanding as a proportion of the total number of days in the period. The weighted average number of securities outstanding is calculated in accordance with the CPA Canada Handbook and as such may be amended or superseded from time to time. The total number of PSUs/RSUs granted in each year (net of awards forfeited during the relevant year) was as follows: 2023 –2,919,948; 2022 – 1,145,902; and 2021 – 862,119. The figures include additional units granted due to dividends paid on Common Shares during the relevant year. The total number of Common Shares that can be issued for vested PSU/RSUs as of December 31, 2023 was 4,173,773 (7,000,000 less 2,826,227 Common Shares issued as at December 31, 2023 to settle prior awards). ALGONQUIN | LIBERTY 66 Bonus deferral program With a view to facilitating increased equity ownership among senior leaders, the board established a bonus deferral program for eligible employees of the Corporation and its affiliates. Employees who hold positions above the level of senior manager are eligible to participate. Eligible employees may elect, prior to any calendar year, to defer up to 100% of their annual STIP award for that year and receive the deferred amount in RSUs issued under the Share Unit Plan. RSUs issued under this program are fully vested and may be settled in Shares issued from treasury, Shares purchased on the secondary market, or in cash (at the Corporation’s election). Any bonus amount deferred is tax-deferred until the issued RSUs are settled. A participating employee may elect at any time after issuance of the RSUs to have them settled at a specified date in the future within the timeframes permitted under the program. The program allows for settlement of RSUs to be deferred for a period ending no later than December 31 of the second year following retirement or termination of employment. Employees receive additional RSUs in an amount equivalent to any dividend payable on an equivalent number of Common Shares during the period up to the settlement date of the RSUs. The additional RSUs issuable to reflect dividend payments are issued at the Market Value (as such term is defined in the Share Unit Plan) on the relevant dividend payment date in accordance with the Share Unit Plan. The table below summarizes certain ratios as of December 31, 2023, 2022, and 2021 regarding the Share Unit Plan, namely dilution, burn rate, and overhang. Dilution and overhang are measured as a percentage of the total number of Common Shares outstanding as of December 31, 2023, 2022, and 2021 and burn rate is measured using the weighted-average number of Common Shares outstanding during the relevant years as noted.

2024 Management Information Circular 67 The ESPP The ESPP enables eligible employees (which includes the NEOs, other than the Interim CEO) to acquire Common Shares in a convenient and systematic manner, thereby facilitating increased levels of equity ownership in the Corporation. The maximum number of Common Shares issuable from treasury under the ESPP is currently 4,000,000, representing approximately 0.58% of the issued and outstanding Common Shares as at December 31, 2023. At the Meeting, Shareholders will be asked to vote on an amendment to the ESPP to increase the maximum number of Common Shares issuable from treasury under the ESPP to 6,500,000 (see page 15). As of December 31, 2023 a total of 3,146,797 Common Shares had been issued from treasury to employees under the ESPP, representing 0.45% of the Issued and outstanding Common Shares as of that date. A total of 853,203 Common Shares remained issuable from treasury under the ESPP as of December 31, 2023, representing 0.13% of the issued and outstanding Common Shares as of that date. All regular full-time and part-time employees of the Corporation (including employees of subsidiaries of the Corporation in North America) are eligible to participate in the ESPP. Participants in the ESPP accumulate funds for the purchase of Common Shares through payroll deduction. For employees who are resident in Canada or who otherwise qualify as Canadian dollar participants under the ESPP, the Corporation matches 20% of the first $5,000 contributed by the employee and 10% of the next $5,000 contributed by the employee, for a maximum matching contribution of $1,500 annually. For employees who are resident in the United States or Bermuda or who have been designated by the Corporation as U.S. dollar participants under the ESPP, the Corporation matches 20% of the first US$5,000 contributed by the employee and 10% of the next US$5,000 contributed by the employee, for a maximum matching contribution of US$1,500 annually. On or about the first business day following the processing of employees’ payroll, all contributions received in respect of each participant are paid in full on behalf of such participant to purchase Common Shares from treasury or, at the election of the Corporation, through market purchases carried out by an independent broker through the facilities of the TSX or NYSE. For employees who are resident in Canada or otherwise qualify as Canadian dollar participants under the ESPP, Common Shares issued from treasury are issued at a price equal to the volume-weighted average trading price of the Common Shares on the TSX for the five trading days immediately preceding the purchase date. For employees who are resident in the United States or Bermuda or who have been designated by the Corporation as U.S. dollar participants under the ESPP, Common Shares issued from treasury are issued at a price equal to the volume-weighted average trading price of the Common Shares on the NYSE for the five trading days immediately preceding the purchase date. Where the Corporation determines that Common Shares purchased by participants will be acquired through market purchases, an equivalent number of Common Shares will be acquired on the applicable market (with any shortfall from contributions for the purchase of such Common Shares being contributed by the Corporation and any excess being available to the Corporation to apply against costs of administering the ESPP). The Common Shares reserved for issuance to insiders under the ESPP, together with any other securities-based compensation arrangements of the Corporation, cannot exceed 10% of the outstanding Common Shares, and the number of Common Shares issued to insiders within a one-year period cannot exceed 10% of the outstanding Common Shares. The ESPP does not set out a maximum number of Common Shares that may be issued to an individual employee; however, eligible employees may only contribute up to a maximum of $10,000 per year in their respective plan participation currency in any given year. This has the effect of limiting the number of Common Shares that may be issued to any one individual under the ESPP. The ESPP can be amended by the board at any time, without the approval of the Shareholders, provided that amendments to: (i) increase the number of Common Shares reserved for issuance from treasury under the ESPP; (ii) add categories of persons eligible to participate under the ESPP; (iii) eliminate or decrease the limitations on insider participation set forth previously; (iv) increase the amount of the contributions of the Corporation under the ESPP, provide for Common Shares to be purchased at a discount, increase the amount of any such discount, or otherwise provide for any additional form of financial assistance to participants; or (v) amend the amending provision of the ESPP to eliminate a matter listed as requiring Shareholder approval, will in each case require Shareholder approval.

The time-weighting factor is the number of days that the securities are outstanding as a proportion of the total number of days in the period. The weighted average number of securities outstanding is calculated in accordance with the CPA Canada Handbook and as such may be amended or superseded from time to time. The total number of Common Shares issued for employee purchases under the ESPP during the years noted were as follows: 2023 – 752,582; 2022 – 450,603; and 2021 – 355,096. The maximum number of Common Shares issuable under the ESPP is currently 4,000,000. As at December 31, 2023 3,146,797 Common Shares had been issued, with an additional 853,203 Common Shares being available for purchase by employees under the ESPP. ALGONQUIN | LIBERTY 68 The defined contribution pension plan The Corporation has established a defined contribution pension plan for its Canadian employees, including the NEOs (other than the Interim CEO) (the “Pension Plan”). Under the Pension Plan, the Corporation contributes 6% of eligible earnings up to the annual limit established by Canada Revenue Agency (“CRA”) on behalf of each NEO (other than the Interim CEO). No matching contributions are required by the NEOs. For Canadian employees other than the NEOs and certain other executive officers, the Corporation provides an annual contribution of 2% of eligible earnings. The Corporation also double-matches up to an additional 2% of eligible earnings contributed by the employee (i.e., if the employee contributed 2% of eligible earnings, the Corporation’s additional contribution would be 4%, up to a maximum contribution equal to the annual limit established by the CRA). Eligible earnings under the Pension Plan are defined as the annual base salary. The Pension Plan is administered on behalf of the Corporation by a major Canadian life insurance company. Under the Pension Plan, employees may retire by ending active employment at any time after reaching the age of 55. Upon retirement, the retired employee will receive retirement income through the purchase of a life or joint life annuity. The amount of retirement income will be dependent upon the accumulated value of the participant’s account in the Pension Plan. There are a number of defined benefit pension plans in place for U.S. employees of operating affiliates of the Corporation. None of the NEOs or other executive officers are eligible to participate in the pension programs offered by the Corporation’s affiliates. The interest of any participant under the ESPP is not assignable either by voluntary assignment or by operation of law, except upon death or upon mental incompetency. Upon the termination of employment of any participant under the ESPP for any reason whatsoever, all Common Shares held in such participant’s account under the ESPP shall be released to such participant. The table below summarizes certain ratios as at December 31, 2023, 2022, and 2021 regarding the ESPP, namely, burn rate and overhang. Overhang is measured as a percentage of the total number of Common Shares outstanding as of December 31, 2023, 2022, and 2021 and burn rate is measured using the weighted-average number of Common Shares outstanding during the relevant years as noted.

As part of their compensation, the NEOs (other than the Interim CEO) are eligible to receive some or all of the following: Some of these items are considered taxable benefits. The monetary value of the benefits is reported in the “Summary compensation table” on page 75. Supplemental executive retirement plan The Corporation has established a supplemental executive retirement plan (“SERP”) to provide a retirement savings program for executives that is aligned with market practices in Canada. Under the SERP, the Corporation annually accrues an amount for eligible executives, including the NEOs (other than the Interim CEO), equivalent to 12% of eligible earnings less any amounts contributed to the Pension Plan during the year. The SERP is an unfunded program under which no annual contributions are funded by the Corporation, with future amounts owing payable from the general revenues of the Corporation. Under the SERP, eligible earnings are the amount of annual base salary and annual cash incentive earned by the participant. Upon cessation of employment with the Corporation, a participant under the SERP receives, at their election, either a one-time taxable lump-sum payment or a series of annual taxable payments for a period not exceeding 15 years with an equal present value. Accrued amounts in the SERP are credited or debited annually by an amount equivalent to the annual return or loss achieved in the Pension Plan, based on the investment mix selected by the participant. The following table shows the accumulated value from January 1, 2023 to December 31, 2023 for each NEO under the Pension Plan and the SERP.

ALGONQUIN | LIBERTY 70 Compensation clawback policy The board has approved a compensation clawback policy applicable to all “Executive Officers” (as that term is defined under applicable securities legislation in Ontario) and to any other employee specifically designated by the HRCC. The policy provides that if there is a restatement of the Corporation’s financial statements due to material non- compliance by the Corporation with any financial reporting requirement under applicable securities laws, then the HRCC shall initiate a process to recoup performance-based compensation paid to the Executive Officers or cancel unpaid or unvested performance-based compensation awarded to the Executive Officers. In this circumstance, the amount to be recouped or cancelled is equal to the difference between the amount of performance-based compensation actually awarded, vested, or paid to the Executive Officers during the relevant period (generally the preceding three years) and the amount of performance-based compensation that would have been awarded, vested, or paid to the Executive Officers had it been calculated or determined based on the Corporation’s restated financial statements. The HRCC may elect not to enforce the clawback policy in limited circumstances following a restatement, including when reasonable attempts have been made to recover the amount and the costs of further enforcement efforts would exceed the amount to be recovered. The HRCC also has discretion under the compensation clawback policy to recoup or cancel performance-based compensation awarded or paid to an Executive Officer if the board determines that he or she was engaged in misconduct (as defined in the policy). In the case of misconduct, the amount of performance-based compensation recouped or cancelled will be at the discretion of the HRCC after taking into account the factors set out in the policy, including: the nature and severity of the misconduct; the Executive Officer’s position and degree of responsibility; the availability of other remedies or penalties that a third party might impose on the Executive Officer or the Corporation; and the harm or potential harm that the misconduct had or may have on the Corporation and its reputation. If a clawback is required by law or regulatory authority, then the amount of the clawback will be determined with reference to the amount required by law or the regulatory authority.

The equity ownership guideline is expressed as a multiple of base salary as shown below. Executive Equity ownership requirement CFO 3x base salary COO, CDO, and CLO 2x base salary The Executive Equity Ownership Guideline provides a transition period for NEOs to achieve their required level of ownership. The transition period ends on the later of: (i) five years from their date of hire or promotion to a NEO role; or (ii) the third anniversary of their most recent salary increase. Notwithstanding the preceding sentence, if a NEO’s ownership falls below the guideline amount due to a decline in the market price of the Common Shares, such NEO will have two years to restore compliance. During such two-year period, such NEO’s equity holdings will be valued at the higher of acquisition cost or market value. If a NEO does not comply with the guideline by the applicable deadline, such NEO must use one-third of his or her base salary to purchase additional Common Shares. In addition, the HRCC may exercise its discretion to award any annual bonus payable to such NEO in the form of Common Shares. Common Shares and vested RSUs are considered equity holdings for the purposes of determining compliance with the Executive Equity Ownership Guideline. NEOs may not sell net after-tax Common Shares issued in settlement of vested PSUs until they have met their guideline amount of equity ownership. The table below shows the equity ownership for each NEO, other than Messrs. Huskilson and Banskota, as of January 2, 2024 using their base salaries in effect on that date. In accordance with the Executive Equity Ownership Guideline, the value is calculated using the volume-weighted average price of the Common Shares on the TSX for the 20 trading days prior to January 2, 2024, which was $8.4966. The equity ownership requirement applicable to Mr. Huskilson is described under “Director equity ownership guideline” on page 18 and his ownership is shown in his profile on page 23.

76 ALGONQUIN | LIBERTY For purposes of compensation, the PSUs were valued using the market price of the Common Shares at the end of the quarter preceding the grant date, as calculated under the Share Unit Plan. For purposes of financial statement disclosure, the PSUs were valued using the closing market price of the Common Shares on the grant date as set out in the table below. The table below shows the difference between the grant date value for compensation purposes and the grant date value used for purposes of financial statement disclosures which is due to the change in market price between those two dates. Grant date Grant date value value for for financial compensation purposes statement disclosure Difference per unit 2023 – March grant $8.94 $10.99 $2.05 2022 – August grant $17.64 $18.04 $0.40 2022 – March grant $18.39 $19.39 $1.00 2021 – March grant $20.99 $19.85 $1.14 Algonquin awarded the number of RSUs to the NEOs as shown in the table below. Mr. Huskilson’s compensation as Interim CEO is paid entirely in the form of RSUs. He received a grant of RSUs on the first business day of October, November, and December 2023 for his service as Interim CEO effective August 10, 2023. The value of the monthly grants was $458,333, except for the initial grant which was valued at $916,670 to account for approximately two months of service. The RSUs granted to Mr. Huskilson were fully vested on their grant dates. They can be redeemed for an equal number of Common Shares at Mr. Huskilson’s election at least two years after the grant dates. The RSUs granted to Mr. Myers in 2023 were a one-time grant for retention purposes with a grant date value of $700,000. Those RSUs vest on March 27, 2026 with a maximum payout value of $1,400,000. The RSUs granted to Mr. Myers in 2022 were an on-hire award worth $300,000 that will vest on August 31, 2025. The RSUs granted to Ms. Tindale in 2023 were a one-time grant for retention purposes with a grant date value of $480,000. Those RSUs vest in three equal tranches on March 27 of 2024, 2025, and 2026. Mr. Banskota received make-whole grants of RSUs in 2022 and 2021 each with a grant date value of $1,000,000. These RSUs vested on February 10, 2023 and February 10, 2022, respectively. The number of RSUs that vest will vary due to the issuance of additional RSUs as dividend equivalents between the grant date and the settlement date. Those additional RSUs are not included in the numbers shown below. Certain NEOs have elected to receive RSU awards under the Bonus Deferral Plan in lieu of a cash award for all or a portion of their annual incentive bonus. These bonus deferral RSUs are not shown in the table below as the cash bonus amounts deferred are included in the Summary Compensation Table under “Annual incentive plans” in the year for which the bonus was awarded. 2023 2022 2021 2022 4.6% 27.3% 2.3% 5.5 $19.11 $3.04 Chris Huskilson 215,226 - - 2021 4.3% 27.3% 1.1% 5.5 $19.64 $2.93 Darren Myers 78,284 17,007 - Johnny Johnston - - - Jeff Norman - - - Jennifer Tindale 53,680 - - Arun Banskota - 54,381 47,631 For purposes of compensation, the RSUs were valued using the market price of the Common Shares at the end of the quarter preceding the grant date as calculated under the Share Unit Plan. For purposes of financial statement disclosure, the RSUs were valued using the closing market price of the Common Shares on the grant date as set out in the following table. The following table shows the difference between the grant date value for compensation purposes and the grant date value used for purposes of financial statement disclosures which is due to the change in market price between those two dates.

For valuation purposes, Mercer used the Black-Scholes Option pricing model with the following assumptions and a 10% minimum value relative to the share price at the time of grant: Dividend Risk-free Expected Exercise Fair Year yield Volatility rate life (years) price value 2023 6.8% 30.3% 2.7% 5.5 $10.76 $1.49 These accounting value assumptions differ from the compensation value assumptions in the calculations above. The difference per Option granted between the two models is presented in the following table: Year Grant date value for compensation purposes Grant date value for financial statement disclosure Difference per Option 2023 $1.49 $1.04 $0.45 2022 $3.04 $2.44 $0.60 2021 $2.93 $2.46 $0.47 Under Mercer’s standard approach, the estimated life of the awards is based on a safe harbour methodology which is shorter in term than the assumed term for accounting purposes. This difference in life affects the calculation of volatility and resulting fair value.

2024 Management Information Circular 77 The annual incentive plan amounts represent the annual bonus earned under the STIP for the relevant year. Amounts shown include, if applicable, the portion of the cash bonus for the year elected by the NEO to be received in RSUs under the bonus deferral program (details of the bonus deferral program are discussed on page 66). Amounts shown are contributions made by the Corporation for the NEOs under the Pension Plan and SERP. Mr. Huskilson was appointed Interim CEO on August 10, 2023. The compensation that he received for serving as a non-employee director from January 1 to August 9, 2023 is shown under “Non-employee director compensation table” on page 45. Mr. Myers was appointed CFO on August 31, 2022. This amount is the aggregate grant date value for compensation purposes of the share unit portion of the annual LTIP award to Mr. Myers of 117,426 PSUs ($1,050,000) and an award of 78,284 RSUs ($700,000) for retention purposes. This amount is the aggregate grant date value for compensation purposes of the on-hire award to Mr. Myers of 26,455 PSUs ($466,667) and 17,007 RSUs ($300,000). The value of the PSU award was the pro-rata amount of his annual target LTIP award for 2022 based on his start date of August 31. The value of the RSU award was intended to reduce the gap between Mr. Myers’s compensation levels at previous employers and his target total direct compensation at Algonquin. This amount is the aggregate grant date value for compensation purposes of the share unit portion of the annual LTIP award to Ms. Tindale of 56,364 PSUs ($504,000) and an award of 53,680 RSUs ($480,000) for retention purposes.

Unvested share-based awards include share units issued as dividend equivalents during the period up to and including December 31, 2023. The market or payout value of unvested PSU awards is calculated based on an assumed performance factor of 1.0 (or target performance) and the closing price of the Common Shares on the TSX on December 29, 2023 of $8.36. Except with respect to Mr. Huskilson, amounts represent the value of PSUs awarded in 2021 and which vested on December 31, 2023. The value shown is calculated based on the closing price of the Common Shares on the TSX on December 29, 2023 of $8.36. The number of PSUs vested was 72.4% of the number of original PSUs granted based upon performance factors achieved and the Corporation’s TSR performance (see “The Share Unit Plan” beginning on page 62) and PSUs issued as dividend equivalents. This amount represents the value of RSUs granted to Mr. Huskilson as the sole form of compensation for his service as Interim CEO and is calculated based on the closing price of the Common Shares on the TSX on December 29, 2023 of $8.36. Mr. Huskilson was appointed as Interim CEO on August 10, 2023. Incentive plan awards – value vested or earned during the year The following table describes all Option-based awards, share-based awards, and non-equity incentives that vested or were earned during 2023 for each NEO.

The 2021 series PSU awards vested at a rate of 72.4% of the original PSUs granted, inclusive of additional PSUs granted as dividend equivalents. The vested value as a multiple of the original grant value was 28.8%. This decrease resulted from the following: the Corporation’s performance during the three-year Performance Period, including its TSR performance, and the decline in share price at the end of the Performance Period compared to the beginning of the Performance Period, partly offset by the value of additional PSUs granted as dividend equivalents (see “The Share Unit Plan” beginning on page 62). This amount is the aggregate value of (i) the third tranche of RSUs granted to Mr. Banskota as a make-whole award upon commencing employment with the Corporation in 2020 and which vested on February 10, 2023 ($575,757); and (ii) the PSUs that vested on August 10, 2023 pursuant to the terms of Mr. Banskota’s separation agreement ($1,926,545) (see “Separation Agreement” on page 82). The closing prices of the Common Shares on the TSX on February 10 and August 10, 2023 were $9.92 and $10.29, respectively.

Employment arrangements The Corporation and its subsidiary, Liberty Utilities (Canada) Corp., have entered into an employment agreement with each NEO. All such employment agreements are collectively referred to as the “Employment Agreements” or individually as an “Employment Agreement”. During 2023, the Corporation also entered into a separation agreement with Mr. Banskota governing the terms of his departure from the role of CEO (the “Separation Agreement”). The terms of the Separation Agreement implemented the termination without cause provisions of Mr. Banskota’s Employment Agreement and are summarized under the heading “Separation Agreement” on page 82. Termination for cause, resignation, resignation for good reason, and change of control Mr. Huskilson’s Employment Agreement is for a fixed term ending on the earlier of: (i) Algonquin’s appointment of a new CEO; and (ii) August 1, 2024 (the “Term”). If Mr. Huskilson’s employment is terminated for cause during the Term, he will be entitled to only the minimum payments and other entitlements, if any, prescribed by applicable employment standards legislation. Mr. Huskilson may resign at any time during the Term by providing at least three months prior written notice. Due to the temporary, fixed-term nature of Mr. Huskilson’s role as Interim CEO, his Employment Agreement does not contain provisions governing a resignation for good reason or the termination of his employment following a change of control. Under the terms of the Employment Agreements with Messrs. Myers, Johnston, and Norman and Ms. Tindale, if there is a termination for cause, he or she will not be entitled to any advance notice of termination or payment in lieu of notice. They may resign at any time during the term of their respective Employment Agreements by providing the contractually required prior written notice (this period ranges from 60 to 90 days). If Messrs. Myers, Johnston, or Norman or Ms. Tindale resign for “Good Reason” (as defined in his or her Employment Agreement), upon resignation he or she will not be entitled to any payment other than any amounts that the Corporation is required to pay in accordance with applicable laws and the Employment Agreement, including payment of accrued but unused vacation and expenses owing. In the case of Messrs. Myers, Johnston, and Norman and Ms. Tindale, if within 18 months following a change of control of the Corporation, either the executive’s employment is terminated without cause or the executive elects to terminate his or her employment because, in the case of Messrs. Johnston and Norman and Ms. Tindale, there has been a material change in employment conditions or duties that would materially adversely affect the nature of his or her responsibilities that has not been cured by the Corporation after written notice, a material reduction in compensation, a change in location of work by more than 50 kilometers, or a material failure to provide benefits and perquisites substantially similar to those provided before the change in control, or in the case of Mr. Myers, because there has been a reduction of 20% or more in his salary or annual target bonus opportunity

2024 Management Information Circular 81 (other than in connection with a reduction applicable to all similarly situated executives of the Corporation), a material adverse change in the scope of his responsibilities, or a relocation of his principal place of business by 100 kilometers or more from the current head office of the Corporation, then these NEOs are entitled to receive compensation equal to the following: (i) a lump-sum payment equal to 24 months of base salary for Mr. Myers or 18 months of base salary for the other executives (at the then applicable base salary rate); (ii) a lump-sum payment equal to the target annual incentive payment for the same period; and (iii) continuation of benefits, allowances, and pension contributions for the same period or a lump-sum payment in lieu thereof. In addition, all unvested PSUs will vest and all unvested Options will vest and be exercisable for 90 days and, in the case of Mr. Myers, all unvested RSUs will vest. In all cases of the vesting of PSUs on termination, the Employment Agreements provide that actual performance achieved is to be used to the extent calculable for periods prior to the termination date and target performance is to be used for subsequent periods. The Employment Agreements for Messrs. Myers, Johnston, and Norman and Ms. Tindale provide that a change of control occurs upon: Any transaction or series of related transactions, whether or not the Corporation is a party thereto, after giving effect to which 50% or more of the Corporation’s voting power is owned, directly or indirectly, through one or more entities, by any person and its affiliates or by one or more groups acting in concert; A sale, lease, or other disposition of all or substantially all of the assets of the Corporation, other than in connection with an internal reorganization; or The board adopts a resolution to the effect that, for the purposes of the Employment Agreement, a change of control has occurred, or that such a change of control is imminent, in which case the date of the change of control shall be deemed to be the date specified in such resolution, provided that the change of control actually occurs. A change of control does not occur where existing controlling Shareholder(s) continue to control more than 50% of the Corporation’s voting power through a new ownership structure. Termination for reasons other than cause Upon termination without cause, Mr. Myers is entitled to the following amounts in lieu of notice: (i) a lump-sum payment equal to 24 months of base salary (at the then applicable base salary rate); (ii) a lump-sum payment equal to the target annual incentive payment for the same period; and (iii) a lump-sum payment in lieu of the amount of contribution that the Corporation would have made for the costs of benefits, allowances, and pension contributions for 24 months. In addition, all unvested RSUs will vest, all unvested PSUs granted in 2023 will vest and all unvested PSUs granted in 2022 which would have vested within 24 months of the last day of employment will vest, in either case as described below, and all unvested Options which would have vested within 24 months of termination will vest and be exercisable for 90 days. Upon termination without cause, Messrs. Johnston and Norman and Ms. Tindale are entitled to the following amounts in lieu of notice: (i) a lump-sum payment equal to 18 months of base salary (at the then applicable base salary rate); (ii) a lump-sum payment equal to the target annual incentive payment for the same period; and (iii) continuation of benefits, allowances, and pension contributions for 18 months or lump-sum payment in lieu thereof. Mr. Norman is also entitled to a lump-sum retention bonus of up to 75% of his base salary, with the actual amount payable based on whether the Corporation completes the sale of its renewable energy business, and a lump-sum transaction bonus of up to 100% of his base salary, provided that the Corporation completes the sale of its renewable energy business and prorated based on the number of complete months of employment between December 1, 2023 and the closing date of the sale. In addition, all unvested PSUs held by Messrs. Johnston and Norman and Ms. Tindale which would have vested within 18 months of termination will vest as described below, and all unvested Options which would have vested within 18 months of termination will vest and be exercisable for 90 days. The Employment Agreements for Messrs. Myers, Johnston, and Norman and Ms. Tindale provide that, in the case of the vesting of PSUs on termination, actual performance achieved is to be used to the extent calculable for periods prior to the termination date and target performance is to be used for subsequent periods.

ALGONQUIN | LIBERTY 82 Separation Agreement Mr. Banskota served as CEO until August 10, 2023. The key terms of the Separation Agreement with Mr. Banskota are set out below. Mr. Banskota received a lump sum payment of $4,500,000 representing 24 months of base salary and target STIP award. He received an additional lump sum payment of $86,232 in lieu of benefits, Pension Plan, and SERP contributions that would have otherwise been made during the 24 months after the end of his employment. Mr. Banskota was paid $42,466 for accrued and unused vacation and is eligible to be reimbursed for up to $10,000 (inclusive of applicable taxes) for tax consulting services. Mr. Banskota received an STIP award for 2023 of $1,113,000, which was 89.0% of his target STIP award of $1,250,000. The amount of Mr. Banskota’s 2023 STIP award was calculated by using the actual 2023 Corporate Scorecard result of 86.3% (weighted 80%) and assuming target for his individual performance and leadership assessment (weighted 20%). The Separation Agreement provided that any unvested PSUs awarded to Mr. Banskota that would have vested by August 10, 2025 vested on August 10, 2023. The performance criteria applicable to such PSUs were determined based on actual performance calculable up to August 10, 2023 and target performance for periods after that date, including with respect to the TSR modifier. These PSUs were settled on August 17, 2023 through the issuance from treasury of 87,003 Common Shares (net of Common Shares set-off for taxes). The closing price of the Common Shares on the TSX on August 17, 2023 was $9.67. The Separation Agreement provided that any unvested Options awarded to Mr. Banskota that would have vested by August 10, 2025 vested on August 10, 2023 and were exercisable for 90 days from that date. All such Options expired unexercised on November 8, 2023. Except with respect to minimum entitlements under employment standards legislation, the payments and benefits provided to Mr. Banskota under the Separation Agreement are subject to his compliance with the terms and conditions of his Employment Agreement and the Separation Agreement, including covenants with respect to confidentiality, non-solicitation, and non-competition. Summary termination table Assuming that the triggering event requiring the foregoing payments occurred on December 31, 2023 and that the Employment Agreements were in effect on such date, the NEOs would be entitled to receive the incremental amounts shown below.

Share-based awards include PSUs and RSUs. The value of Mr. Norman’s bonus entitlement includes the maximum amounts payable pursuant to his retention and transaction bonuses described on the preceding page. The actual amounts payable would be dependent on completion of a sale of the Corporation’s renewable energy business and the amount of time between the termination date and the closing date. The value of Mr. Banskota’s share-based awards is equal to the number of PSUs that vested on August 10, 2023 pursuant to the terms of the Separation Agreement multiplied by the closing price of the Common Shares on the TSX on that date, which was $10.29. Indebtedness of directors and others No current or former directors or officers of Algonquin, or any of its subsidiaries had any loans with Algonquin or any of its subsidiaries at any time in 2023.

ALGONQUIN | LIBERTY 84 Schedule “A” Description of the Share Unit Plan The Share Unit Plan is administered by a committee consisting of designated executives of the Corporation or its relevant affiliates, except that in respect of any grants made to members of the Corporation’s executive team (including the NEOs), the committee designated as the administrator is the HRCC (in either case, referred to below as the “Plan Committee”). PSUs and RSUs may be granted under the Share Unit Plan. In the case of PSUs, the Plan Committee may determine performance criteria that may increase or decrease the number of PSUs that vest at the end of the Performance Period depending on achievement relative to the performance criteria targets. RSUs are not subject to performance criteria and are time vested. Awards granted under the Share Unit Plan are made by reference to a specified dollar value (the “Award Value”). The number of PSUs or RSUs granted to a participant is determined by dividing the Award Value by the Market Value (as defined below) of the Common Shares as of the grant date, rounded down to the next whole number. The “Market Value” for purposes of the Share Unit Plan is (i) the volume-weighted average trading price of the Common Shares on the TSX (or such other stock exchange in Canada on which the Common Shares are traded) for the five trading days preceding the date in question, or (ii) if the Common Shares are not traded on a stock exchange, the fair market value of the Common Shares as determined by the Plan Committee. Vested PSUs and RSUs may be settled at the option of the Corporation in (i) Common Shares issued from treasury, (ii) Common Shares purchased on the secondary market, or (iii) cash. Any payment in cash to settle a vested PSU or RSU is based on the Market Value of the Common Shares on the vesting date. Awards under the Share Unit Plan will not be paid in Common Shares issued from treasury if, at the time of such issuance, such issuance could result, at any time, in the number of Common Shares reserved for issuance to insiders (as defined in the TSX Company Manual) under such plan, together with Common Shares reserved for issuance to insiders under all other securities-based compensation arrangements (as defined in the TSX Company Manual), exceeding 10% of the issued and outstanding Common Shares, or if the issuance to insiders, within a one-year period, of a number of Common Shares under such plan, together with Common Shares that may be issued to insiders under all other securities-based compensation arrangements, could exceed 10% of the issued and outstanding Common Shares (collectively, the “Insider Participation Limit”). Other than the Insider Participation Limit, there is no maximum number of Common Shares that may be issued to any one individual under the Share Unit Plan. Where a participant’s employment is terminated by reason of the participant’s death prior to the vesting of such participant’s PSUs or RSUs, (i) the PSUs credited to the participant’s account as at December 31 of the year preceding the participant’s death will continue to be eligible for vesting and (ii) the RSUs credited to the participant’s account as at December 31 of the year preceding the participant’s death will vest as of the participant’s date of death. Where a participant’s employment is terminated due to a qualifying retirement, the participant’s unvested PSUs remain eligible for pro-rata vesting on the same basis as PSUs held by continuing participants. For the purposes of the Share Unit Plan, a qualifying retirement is a bona fide retirement in which the participant (i) provides at least six months’ advance notice, (ii) is at least 65 years of age or at least 55 years of age and with a combined age and years of service with the Corporation of at least 70, and (iii) works cooperatively during the notice period to transition his or her responsibilities to one or more successors. The Plan Committee has the discretion to determine that a resignation that does not meet the retirement conditions specified in the Share Unit Plan will nonetheless be treated as a qualifying retirement. Where a participant takes a leave of absence from the Corporation or an affiliate, as applicable, for a period of at least 90 days prior to the vesting date, such participant’s PSUs and RSUs will continue to be eligible for vesting, but at a prorated rate based on the number of whole and partial months that the participant was an active employee between the date of the award and the vesting date. Where the leave of absence extends beyond the vesting date and the participant fails to return to full-time employment within 180 days after such vesting date, no PSUs or RSUs that would otherwise have vested will vest, and the participant will receive no payment or compensation therefor. Subject to the qualifying retirement provisions described above, unless otherwise determined by the Plan Committee or except as otherwise provided in an agreement with a participant, if prior to the vesting date a participant’s employment is terminated by the Corporation or an affiliate for any reason or the participant voluntarily

2024 Management Information Circular 85 terminates his or her employment with the Corporation or an affiliate, no portion of the PSUs or RSUs that would otherwise vest on the vesting date will vest, and such participant will receive no payment or compensation therefor. Unless otherwise determined by the Plan Committee or otherwise provided in an agreement between the Corporation and a participant, the occurrence of a change of control of the Corporation will not result in the vesting of PSUs or RSUs provided that (i) such unvested PSUs and RSUs continue to vest in accordance with the terms of the Share Unit Plan and relevant award agreement, and (ii) the entity that acquires control of, or otherwise becomes a successor to, the Corporation agrees to assume the obligations of the Corporation in respect of such PSUs and RSUs. Except where a successor entity provides participants with a substantially equivalent award on certain prescribed terms, the Plan Committee has discretion to cancel all outstanding PSUs and RSUs upon a change of control and to determine that the value of all such awards will be paid out in cash in an amount based on the price at which the Common Shares are valued for the purposes of the transactions giving rise to the change of control. The assignment or transfer of PSUs or RSUs, or any other benefits under the Share Unit Plan, is not permitted, other than by operation of law. The Share Unit Plan may be amended or terminated at any time by the Plan Committee in whole or in part, without Shareholder approval, provided that: no amendment of the Share Unit plan will, without the consent of the participants affected by the amendment, or unless required by applicable law, adversely affect the rights of such participants with respect to PSUs or RSUs granted prior to the date of the amendment; no amendment of the Share Unit Plan will be effective unless such amendment is approved by the TSX; and c) approval by a majority of the votes cast by Shareholders present and voting in person or by proxy at a meeting of Shareholders shall be obtained for any: i. amendment for which, under the requirements of any applicable law, Shareholder approval is required; ii. reduction of the purchase price of Common Shares issued or purchased to settle awards granted under the plan or the cancellation and re-issuance of awards under the plan; iii. extension of the term of an award under the plan beyond the original expiry date of the award; iv. amendment to remove or exceed the Insider Participation Limit; v. increase to the maximum number of Common Shares issuable from treasury under the plan; vi. amendments to eligible participants that may permit the introduction of non-employee directors on a discretionary basis; vii. allowance of awards granted under the plan to be transferable or assignable other than for estate settlement purposes; or viii. amendment to the amendment provision of the plan.

An account (“Account”) shall be maintained by the Corporation for each award made to each Participant pursuant to an Award Agreement and which will be credited with an opening balance equal to the Award PSUs and/or Award RSUs granted pursuant to such Award Agreement.

The number of such additional PSUs or RSUs to be credited to the Participant’s Account in respect of any particular dividend paid on the Shares will be calculated by dividing (i) the amount of the cash dividend that would have been paid to the Participant if each of the PSUs and RSUs recorded in the Participant’s Account as at the record date for the cash dividend had been Shares by (ii) the Market Value on the date on which the dividend is paid on the Shares. Dividend Equivalent Units shall be Vested to the same extent and paid at the same time as the PSUs or RSUs, as applicable, to which they relate and shall be considered to be designated as payable in Shares or in cash as the related PSUs or RSUs in the Participant’s Account are so designated. 5.3 Adjustments. In the event of any stock dividend, stock split, combination or exchange of shares, capital reorganization, consolidation, spin off or other distribution (other than normal cash dividends) of the Corporation’s assets to shareholders, or any other similar changes affecting the Shares, proportionate adjustments to reflect such change or changes shall be made with respect to the number of PSUs and RSUs outstanding under the Plan, or securities into which the Shares are changed or are convertible or exchangeable and as may be substituted for Shares under this Plan, on a basis proportionate to the number of PSUs and RSUs in the Participant’s Account or some other appropriate basis, all as determined by the Committee in its sole discretion. 6.

Any issuances of Shares from treasury to pay awards as contemplated by Section 7.4 shall be issued at a price per Share equal to the Market Value on the date of issuance. 6.4 Insider Participation Limit. Awards under the Plan shall not be paid in Shares issued from treasury if, at the time of such issuance, such issuance could result, at any time, in: 6.4.1 the number of Shares reserved for issuance to Insiders under the Plan, together with Shares reserved for issuance to Insiders under all other Securities-Based Compensation Arrangements, exceeding 10% of the issued and outstanding Shares; or 6.4.2 the issuance to Insiders, within a one year period, of a number of Shares under the Plan, together with Shares that may be issued to Insiders under all other Securities-Based Compensation Arrangements, exceeding 10% of the issued and outstanding Shares.

100 ALGONQUIN | LIBERTY Schedule “C” Description of the DSU Plan The DSU Plan provides that, subject to the terms of the DSU Plan and such other conditions are the HRCC may impose, a director who is not an employee of the Corporation or an affiliate of the Corporation (an “Eligible Director”) may elect to receive his or her Annual Cash Remuneration (as defined below) in the form of DSUs, cash, or any combination of DSUs and cash. An Eligible Director’s “Annual Cash Remuneration” is all of the amounts ordinarily payable in cash to such director in respect of the services provided by such director to the Corporation as a member of the board in a calendar year (including any annual retainers and fees for serving as the chair or a member of a committee, but excluding meeting fees and travel fees). All DSUs issued with respect to Annual Cash Remuneration will be credited to the Eligible Director’s DSU account on each conversion date (generally being the last day of a quarter or such other dates as determined by the board or the Corporate Governance Committee), by dividing the portion of the Eligible Director’s Annual Cash Remuneration for the applicable period to be paid in the form of DSUs by the Fair Market Value of the Common Shares on the conversion date. For the purposes of the DSU Plan, the “Fair Market Value” of the Common Shares is the volume-weighted average trading price of the Common Shares on the TSX for the five days immediately preceding the date in question. On each payment date for dividends paid on Common Shares, an Eligible Director’s DSU account will also be credited with dividend equivalents on the DSUs credited to such account as of the record date for such dividends. Such dividend equivalents shall be converted into additional DSUs (including fractional DSUs) based on the Fair Market Value of the Common Shares as of the date on which the dividends on the Common Shares are paid. Each Eligible Director shall be entitled to redeem his or her DSUs following the date upon which he or she ceases to hold any position as a director or a director of the Corporation’s affiliates and is no longer otherwise employed by the Corporation or its affiliates, including in the event of death of the Eligible Director (the “Termination Date”). The Eligible Director may elect up to two separate dates, between the Termination Date and December 15 of the year following the year in which the Termination Date occurs, as of which either a portion or all of the DSUs credited to such Eligible Director’s account shall be redeemed (each such date being an “Entitlement Date”). For directors resident or a citizen of the U.S. (each, a “U.S. Director”), such election must be made at the same time as the U.S. Director elects to receive DSUs. In addition, the DSU Plan contains certain terms and conditions relating to administration of the DSU Plan with respect to U.S. Directors and elections by U.S. Directors under the DSU Plan to ensure compliance with Section 409A of the U.S. Internal Revenue Code of 1986, as amended, and applicable regulations thereunder. Where an Eligible Director does not select an Entitlement Date or Entitlement Dates, there will be a single Entitlement Date being December 15 of the year following the year in which such director’s Termination Date occurs (subject to extension, to no later than December 31 of such year, in the event that the Corporate Governance Committee is unable to compute the final value of DSUs recorded in the director’s DSU account by reason of unavailability of market value data), other than in the case of the death of a U.S. Director, in which circumstances payment shall be made no later than December 31 of the calendar year in which the death occurs or, if later, the 15th day of the third month following such U.S. Director’s date of death. An Eligible Director (or the beneficiary of an Eligible Director, as the case may be) who redeems DSUs is entitled to receive cash, Common Shares or a combination of cash and Common Shares, at the discretion of the board. Where settlement of any DSUs is made in cash, the Eligible Director (or his or her beneficiary) will, subject to any withholding tax, receive a lump sum cash payment equal to the Fair Market Value of the Common Shares on the payment date multiplied by the number of whole and fractional DSUs being settled by way of such cash payment. Settlement of DSUs in Common Shares may be made by Common Shares issued from treasury (without the issuance of any fractional Common Shares, the entitlement for which will be cancelled without payment) or through Common Shares purchased on the open market by an independent broker. Rights of Eligible Directors respecting DSUs and other benefits under the DSU Plan shall not be transferable or assignable other than by will or the laws of descent and distribution.

2024 Management Information Circular 101 The board may, without Shareholder approval, amend, suspend or cancel the DSU Plan or DSUs granted thereunder as it deems necessary or appropriate, provided that: any approvals required under applicable law or the applicable stock exchange rules are obtained; Shareholder approval will be sought where the proposed amendment results in: an increase in the maximum number of Common Shares issuable from treasury under the DSU Plan; a change in the definition of Fair Market Value which would result in a decrease in the value of DSUs redeemed under the DSU Plan; a change in the term of any DSUs; a change in the vesting provisions of the DSU Plan; or an amendment to the amending provisions of the DSU Plan; and no such amendment shall, without the consent of an Eligible Director or unless required by law, adversely affect the rights of such Eligible Director with respect to any amount in respect of which such Eligible Director has then elected to receive DSUs or DSUs which such Eligible Director has then been granted under the DSU Plan. The DSU Plan also provides that the maximum number of Common Shares issuable to insiders (as that term is defined by the TSX) pursuant to the DSU Plan, together with any Common Shares issuable pursuant to any other securities-based compensation arrangement of the Corporation, will not exceed 10% of the total number of outstanding Common Shares. Further, the maximum number of Common Shares issued to insiders within a one-year period pursuant to the DSU Plan and any other securities-based compensation arrangement of the Corporation shall not exceed 10% of the total number of outstanding Common Shares.

2024 Management Information Circular 105 Schedule “E” Description of the Option Plan Under the Option Plan: subject to the terms of the Option Plan, the number of Common Shares subject to each Option, the exercise price of each Option, the expiration date of each Option, the extent to which each Option vests and is exercisable from time to time during the term of the Option and other terms and conditions relating to each Option will be determined by the board (or a committee of the board) from time to time; subject to any adjustments pursuant to the provisions of the Option Plan, the exercise price of any Option shall under no circumstances be lower than the “Market Price” (being the five-day volume-weighted average trading price on the TSX) of the Common Shares on the date on which the board approves the grant of the Option; the term of an Option shall not exceed 10 years from the date of the grant of the Option, subject to certain limited exceptions, including that if the expiration date for an Option occurs during a period of time during which the person granted Options (an “Optionee”) cannot exercise an Option, or sell the Common Shares issuable pursuant to an exercise of Options, due to applicable policies of the Corporation in respect of insider trading (a “Blackout Period”) applicable to the relevant Optionee, or within 10 business days after the expiry of a Blackout Period applicable to the relevant Optionee, then the expiration date for that Option shall be the date that is the 10th business day after the expiry date of the Blackout Period; Options will be personal to the grantee and will be nontransferable and non-assignable, except in certain limited circumstances; the maximum number of Common Shares which may be reserved for issuance to insiders under the Option Plan, together with the number of Common Shares reserved for issuance to insiders under any other securities-based compensation arrangement, shall be 10% of the Common Shares outstanding at the time of the grant; the maximum number of Common Shares which may be issued to insiders under the Option Plan and all other securities-based compensation arrangements within a one-year period shall be 10% of the Common Shares outstanding at the time of the issuance; participation in the Option Plan by non-employee directors shall be limited to the lesser of (i) a reserve of 1% of the issued and outstanding Common Shares from time to time for non-employee directors as a group and (ii) an annual equity award value under the Option Plan of $100,000 per non-employee director (no Options have ever been granted to non-employee directors); the Corporation may withhold from amounts payable to an Optionee such amounts as may be necessary to enable the Corporation to comply with applicable requirements of tax laws relating to the withholding of tax or other required deductions with respect to Options, and the Corporation may satisfy any liability for any such withholding obligations by (i) selling on behalf of any Optionee (or causing an Optionee to sell) Common Shares issuable under an Option or retaining any amount payable to the Optionee or (ii) requiring the Optionee, as a condition to the exercise of Options, to make such arrangements as the Corporation may require so that the Corporation can satisfy such withholding obligations; and If the Corporation restates its financial results, unexercised Options may be cancelled in accordance with the terms of the Corporation’s clawback policy. The Option Plan provides that, except as set out in the Option Plan or any resolution passed at any time by the board or the terms of any Option agreement or employment agreement with respect to any Option or Optionee, an Option and all rights to purchase Common Shares pursuant thereto shall expire and terminate immediately upon the Optionee who holds such Option ceasing to be an Eligible Person. Where an Optionee (other than a “Service Provider”, as defined in the Option Plan) resigns from the Corporation or is terminated by the Corporation for cause, the Optionee’s unvested Options shall immediately be forfeited and the Optionee’s vested Options may be exercised for 30 days after the date of resignation or termination. Where an Optionee (other than a Service Provider) retires from the Corporation or ceases to serve the Corporation or an affiliate as a director, officer or employee for any reason other than a termination by the Corporation for cause, the board may at its discretion accelerate the vesting of unvested Options then held by the Optionee and the Optionee’s vested Options may be exercised within 90 days after such retirement or termination. The board has adopted a Board Approved Retirement Guideline pursuant to which vesting of Options awarded to certain eligible individuals may under certain circumstances continue to vest in connection with a Board-approved retirement for a period no longer than two years post-retirement. The extension of the vesting period is subject to certain conditions set out in the guideline, including a requirement to continue to hold a specified amount of equity investment in the Corporation for a period following retirement.

106 ALGONQUIN | LIBERTY If an Optionee (other than a Service Provider) has suffered a permanent disability, Options previously granted to such Optionee shall continue to vest and be exercisable in accordance with the terms of the grant and the provisions of the Option Plan, but no additional grants of Options may be made to the Optionee. If an Optionee (other than a Service Provider) dies, all unexercised Options held by such Optionee at the time of death immediately vest, and such Optionee’s personal representatives or heirs may exercise all Options within one year after the date of such death. All Options granted to Service Providers terminate in accordance with the terms, conditions and provisions of the associated Option agreement between the Corporation and such Service Providers, provided that such termination shall occur no later than the earlier of (i) the original expiry date of the term of the Option and (ii) one year following the date of termination of the engagement of the Service Provider. Options may be exercised in accordance with the specific terms of their grant and by the Optionee delivering the exercise price to the Corporation for all of the Options exercised. The Optionee may also elect to surrender Options and receive in exchange for each such Option, at the election of the Corporation, either cash or Common Shares equal to the amount by which the Market Price of the Common Shares exceeds the exercise price of the Option. The board may amend, suspend or discontinue the Option Plan or amend Options granted under the Option Plan at any time without Shareholder approval, provided that: a) approval by a majority of the votes cast by Shareholders present and voting in person or by proxy at a meeting of Shareholders of the Corporation must be obtained for any: i. amendment for which, under the requirements of the TSX or any applicable law, Shareholder approval is required; ii. increase to the maximum number or percentage of securities issuable under the Option Plan; iii. reduction of the Option price, or cancellation and re-issuance of Options or other entitlements, of Options granted under the Option Plan; extension of the term of Options beyond the original expiry date; change in Eligible Persons that may permit the introduction or reintroduction of non-employee directors on a discretionary basis; vi. increase to the limit imposed on non-employee director participation set out in the Option Plan; vii. allowance of Options granted under the Option Plan to be transferable or assignable other than for estate settlement purposes; or viii. amendment to the Option Plan’s amendment provisions; and b) the consent of the Optionee is obtained for any amendment which alters or impairs any Option previously granted to an Optionee under the Option Plan. Notwithstanding the other provisions of the Option Plan, if: a) the Corporation proposes to amalgamate, merge or consolidate with any other corporation (other than a wholly owned affiliate) or to liquidate, dissolve or wind-up; b) an offer to purchase or repurchase all of the Common Shares shall be made to all Shareholders which offer has been approved or accepted by the board; or c) the Corporation proposes the sale of all or substantially all of the assets of the Corporation as an entirety, or substantially as an entirety so that the Corporation shall cease to operate any active business; then the Corporation will have the right, upon written notice thereof to Optionees, to permit the exercise of all such Options, whether or not vested, within the 20-day period following the date of such notice and to determine that upon the expiration of such 20-day period, all rights of the Optionee to such Options or to exercise same (to the extent not theretofore exercised) shall ipso facto terminate and cease to have further force or effect whatsoever. The TSX Company Manual requires the Option Plan to be put before Shareholders for re-approval within three years of the date of the last meeting of Shareholders at which the plan was approved and every three years thereafter.
