ANNUAL INFORMATION FORM
The Annual Information Form (the “AIF”) of Algonquin Power & Utilities Corp. (“APUC” or the “Company”) for the fiscal year ended December 31, 2019 is filed as Exhibit 99.1 to this annual report on Form 40-F. All capitalized terms used herein but not otherwise defined herein shall have the meanings given to such terms in the AIF.
AUDITED ANNUAL FINANCIAL STATEMENTS
The Audited Annual Financial Statements of APUC for the fiscal year ended December 31, 2019 (the “Financial Statements”) are filed as Exhibit 99.2 to this annual report on Form 40-F.
MANAGEMENT’S DISCUSSION AND ANALYSIS
The Management’s Discussion and Analysis for the fiscal year ended December 31, 2019 (the “MD&A”) is filed as Exhibit 99.3 to this annual report on Form 40-F.
DISCLOSURE CONTROLS AND PROCEDURES
The information provided under the heading “Disclosure Controls and Procedures” in the MD&A, filed as Exhibit 99.3 to this annual report on Form 40-F, is incorporated by reference herein.
INTERNAL CONTROL OVER FINANCIAL REPORTING
A. Management’s report on internal control over financial reporting
The Company’s management, including its chief executive officer and chief financial officer, is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”).
The Company’s internal control over financial reporting framework includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. GAAP, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the Company’s consolidated financial statements.
Due to its inherent limitations, internal control over financial reporting may not prevent or detect all misstatements. Further, the effectiveness of internal control is subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies or procedures may change.
During the year ended December 31, 2019, the Company acquired Enbridge Gas New Brunswick Limited Partnership ("New Brunswick Gas") and St. Lawrence Gas Company, Inc. ("St. Lawrence Gas"). Management is in the process of evaluating the existing controls and procedures of New Brunswick Gas and St. Lawrence Gas and integrating financial reporting and controls for New Brunswick Gas and St. Lawrence gas into the Company's internal control over financial reporting. The financial information for these acquisitions is included in the MD&A and in note 3 to the Financial Statements. As permitted under applicable laws, due to the complexity associated with assessing internal controls during integration efforts, the Company excluded these acquisitions from its evaluation of the effectiveness of the Company's internal controls over financial reporting as of December 31, 2019 (representing approximately 4% of our total assets as of December 31, 2019 and approximately 2% of our revenues for the year ended December 31, 2019).
Management assessed the effectiveness of APUC’s internal control over financial reporting as of December 31, 2019, based on the framework established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). This assessment evaluation included review of the documentation of controls, evaluation of the design effectiveness of controls, testing of the operating effectiveness of controls and a conclusion on this evaluation. Based on this assessment, management concluded that APUC’s internal

control over financial reporting was effective as of December 31, 2019 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external reporting purposes in accordance with U.S. GAAP. Management reviewed the results of its assessment with the Audit Committee of the Board of Directors of the Company.
B. Auditor’s attestation report on internal control over financial reporting
Ernst & Young LLP, the independent registered public accounting firm of APUC, which audited the consolidated financial statements of APUC for the year ended December 31, 2019, has also issued an attestation report on the effectiveness of APUC’s internal control over financial reporting as of December 31, 2019. The attestation report is provided in Exhibit 99.2 to this annual report on Form 40-F and is incorporated by reference herein.
C. Changes in internal control over financial reporting
The information provided under the heading “Changes in Internal Controls Over Financial Reporting” in the MD&A, filed as Exhibit 99.3 to this annual report on Form 40-F, is incorporated by reference herein.
AUDIT COMMITTEE FINANCIAL EXPERTS
APUC’s board of directors has determined that it has two audit committee financial experts serving on its audit committee. Christopher Ball and Dilek Samil have been determined to be such audit committee financial experts and are “independent” as set forth in the Canadian National Instrument 58-101 Disclosure of Corporate Governance Practices and Rule 10A-3 of the Exchange Act. The SEC has indicated that the designation as an audit committee financial expert does not make a person an “expert” for any purpose, impose any duties, obligations or liability on such persons that are greater than those imposed on members of the audit committee and board of directors who do not carry this designation or affect the duties, obligations or liability of any other member of the audit committee or board of directors.
CODE OF ETHICS
APUC has adopted a code of business conduct and ethics (the “Code of Conduct”) that applies to all employees and officers, including its Chief Executive Officer and Chief Financial Officer. The Code of Conduct is available without charge to any shareholder upon request to Amelia Tsang, Telephone: (905) 465-4500, E-mail: InvestorRelations@APUCorp.com, Algonquin Power & Utilities Corp., 354 Davis Road, Oakville, Ontario L6J 2X1.
PRINCIPAL ACCOUNTANT FEES AND SERVICES
The information provided under the heading “Pre-Approval Policies and Procedures” in the AIF, filed as Exhibit 99.1 to this annual report on Form 40-F, is incorporated by reference herein. All audit services, audit-related services, tax services, and other services provided for the years ended December 31, 2018 and 2019 were pre-approved by the audit committee.
OFF-BALANCE SHEET ARRANGEMENTS
APUC’s off-balance sheet arrangements consist of obligations under equity capital contribution agreements and guarantees for certain development projects which the Company does not have sole control. These instruments provide financial assurance necessary for the continued development and construction of the projects. APUC also pledged its shares in Atlantica Yield plc (“Atlantica”) as collateral to a secured credit facility issued by the Company’s equity-method investee. For a discussion of these arrangements, refer to the information in note 8 to the Financial Statements, filed as Exhibit 99.2 to this annual report on Form 40-F and is incorporated by reference herein, and the information under the heading “Enterprise Risk Management – Operational Risk Management – Joint Venture Investment Risk” in the MD&A, filed as Exhibit 99.3 to this annual report on Form 40-F and is incorporated by reference herein.

TABULAR DISCLOSURE OF CONTRACTUAL OBLIGATIONS
The information provided under the heading “Contractual Obligations” in the MD&A, filed as Exhibit 99.3 to this annual report on Form 40-F, is incorporated by reference herein.
NON-GAAP FINANCIAL MEASURES
The AIF and MD&A contain financial measures that are not recognized measures under U.S. GAAP. Such terms include: “Adjusted Net Earnings”, “Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization” (“Adjusted EBITDA”), “Adjusted Funds from Operations”, “Net Energy Sales”, “Net Utility Sales” and “Divisional Operating Profit”. There is no standardized measure of these terms and, consequently, the Company’s method of calculating these measures may differ from methods used by other companies and may not be comparable to similar measures presented by other companies. A calculation and analysis of “Adjusted Net Earnings”, “Adjusted EBITDA”, “Adjusted Funds from Operations”, “Net Energy Sales”, “Net Utility Sales”, and “Divisional Operating Profit” can be found in the MD&A, which is attached hereto as Exhibit 99.3 and incorporated herein by reference.

COMPARISON OF NYSE CORPORATE GOVERNANCE RULES
APUC is subject to corporate governance requirements prescribed under applicable Canadian corporate governance practices, including the rules of the Toronto Stock Exchange (“Canadian Rules”). APUC is also subject to corporate governance requirements prescribed by the listing standards of the New York Stock Exchange (“NYSE”) Stock Market, and certain rules and regulations promulgated by the SEC under the Exchange Act (including those applicable rules and regulations mandated by the Sarbanes-Oxley Act of 2002). In particular, Section 303A.00 of the NYSE Listed Company Manual requires APUC 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 APUC 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. APUC’s Board of Directors is responsible for determining whether or not each director is independent. In making this determination, the Board of Directors has adopted the definition of “independence” as set forth in the Canadian National Instrument 58-101 Disclosure of Corporate Governance Practices. In applying this definition, the Board of Directors considers all relationships of its directors, including business, family and other relationships. APUC’s Board of Directors also determines whether each member of its Audit Committee is independent pursuant to Canadian National Instrument 52-110 Audit Committees 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. APUC’s Corporate Governance Committee includes one director who is not independent, but the Committee has appointed a Nominating Sub-Committee consisting solely of independent directors that performs all responsibilities relating to the director nominations process.
Section 303A.05(a) of the NYSE Listed Company Manual requires that all members of the compensation committee be independent.
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 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 written charter of the audit committee complies with Canadian Rules, but does not explicitly state that these functions are part of the purpose of the audit committee, 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. APUC 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, or 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 listed companies adopt and disclose corporate governance guidelines that address certain topics, including director compensation guidelines. APUC has adopted its Board Mandate, which is the equivalent of corporate governance guidelines, in compliance with the Canadian Rules.

APUC’s corporate governance guidelines do not address director compensation, but APUC provides disclosure about the decision making process for non-employee director compensation in the annual management information circular and APUC has adopted a policy on share 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. APUC’s code of business conduct and ethics complies with Canadian Rules and does not include such a requirement.
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 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. APUC will follow the Canadian Rules for shareholder approval of new issuances of its common shares. Following the Canadian Rules, shareholder approval is required for certain issuances of shares that (i) materially affect control of APUC or (ii) provide consideration to insiders in aggregate of 10% or greater of the market capitalization of the listed issuer 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 the listed issuer 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 Company 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 Company expects to make the disclosure of such transactions available on the Company’s website at www.algonquinpowerandutilities.com. Information contained on the Company’s website is not part of this annual report on Form 40-F.
UNDERTAKING
APUC undertakes to make available, in person or by telephone, representatives to respond to inquiries made by the Commission staff, and to furnish promptly, when requested to do so by the Commission staff, information relating to the securities in relation to which the obligation to file an annual report on Form 40-F arises or transactions in said securities.
