The Notes, including accrued and unpaid interest thereon, will be converted automatically (an “Automatic Conversion”), without the consent of the holders thereof, into shares of a newly-issued series of preferred shares of the Corporation (the “Conversion Preferred Shares”) upon the occurrence of an Automatic Conversion Event (as defined herein). As the events that give rise to an Automatic Conversion are bankruptcy and related events, it is in the interest of the Corporation to ensure that an Automatic Conversion does not occur, although the events that could give rise to an Automatic Conversion may be beyond the Corporation’s control.

The Corporation may, at its option, on giving not more than 60 days’ nor less than 30 days’ prior notice to the holders, redeem the Notes, in whole at any time or in part from time to time, on any date during a Par Call Period (as defined herein) at a redemption price equal to 100.00% of the principal amount of the Notes redeemed together with accrued and unpaid interest (including deferred interest, if any) thereon to, but excluding, the date fixed for redemption. At any time not during a Par Call Period, the Corporation may, at its option, on giving not more than 60 days’ nor less than 30 days’ prior notice to the holders, redeem the Notes, in whole at any time or in part from time to time, at a redemption price equal to the greater of (i) 100.00% of the principal amount of the Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on such Notes (not including any portion of such payments of interest accrued as of the date fixed for redemption) that would be due if the Notes matured on the first day of the next succeeding Par Call Period, discounted to the date fixed for redemption (assuming a 360-day year comprising twelve 30-day months) at the Treasury Rate (as defined herein) plus 50 basis points and on a semi-annual basis; plus, in each case, accrued and unpaid interest (including deferred interest, if any) thereon to, but excluding, the date fixed for redemption. Any such optional redemption may be subject to such conditions as may be specified in the applicable notice of redemption.

After the occurrence of a Tax Event (as defined herein), the Corporation may, at its option, redeem all (but not less than all) of the Notes at a redemption price equal to 100.00% of the principal amount thereof, together with accrued and unpaid interest (including deferred interest, if any) thereon to, but excluding, the date fixed for such redemption.

At any time within 120 days following the occurrence of a Rating Event (as defined herein), the Corporation may, at its option, redeem all (but not less than all) of the Notes at a redemption price equal to 102.00% of the principal amount thereof, together with accrued and unpaid interest (including deferred interest, if any) thereon to, but excluding, the date fixed for such redemption.

For greater clarity, notwithstanding the occurrence of a Tax Event or Rating Event, the Corporation shall continue to have the option to redeem the Notes in accordance with its optional redemption right described above.

The Underwriters, as principals, conditionally offer the Notes in the U.S., subject to prior sale, if, as and when issued and sold by the Corporation and accepted by the Underwriters in accordance with the conditions contained in the Underwriting Agreement and referred to under “Underwriting” and subject to the approval of certain legal matters on behalf of the Corporation by Blake, Cassels & Graydon LLP, as to Canadian matters, and Gibson, Dunn & Crutcher LLP, as to U.S. matters, and on behalf of the Underwriters by Cravath, Swaine & Moore LLP, as to U.S. matters, and Bennett Jones LLP, as to Canadian matters.

The Corporation does not intend to apply to list the Notes on any securities exchange or quotation system and, consequently, there is no market through which the Notes may be sold and purchasers may not be able to resell the Notes purchased under this Prospectus Supplement and the Base Shelf Prospectus to which it relates. This may affect the pricing of the Notes in the secondary market, the transparency and availability of trading prices, the liquidity of the Notes, and the extent of issuer regulation. See “Risk Factors.”

An investment in the Notes is subject to certain risks. Furthermore, an investment in the Notes could be replaced in certain circumstances, without the consent of the holder, by Conversion Preferred Shares. Prospective purchasers should therefore carefully consider the disclosure with respect to the Corporation and the Conversion Preferred Shares included and incorporated by reference in this Prospectus Supplement. See “Risk Factors.”

Owning the Notes may subject you to tax consequences both in the United States and Canada. See “Certain Canadian Federal Income Tax Considerations” and “Certain U.S. Federal Income Tax Considerations” in this Prospectus Supplement.

The enforcement by investors of civil liabilities under U.S. federal securities laws may be affected adversely by the fact that the Corporation is incorporated under the laws of Canada, that most of its officers and some of its directors are residents of Canada and that a portion of the assets of the Corporation and said persons are located outside the U.S. See “Enforcement of Certain Civil Liabilities” in this Prospectus Supplement and in the Base Shelf Prospectus.

NEITHER THE U.S. SECURITIES AND EXCHANGE COMMISSION (THE “SEC”) NOR ANY STATE OR CANADIAN SECURITIES REGULATOR HAS APPROVED OR DISAPPROVED THE NOTES OR DETERMINED IF THIS PROSPECTUS SUPPLEMENT IS TRUTHFUL OR COMPLETE. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE.

Morgan Securities LLC, RBC Capital Markets, LLC, TD Securities (USA) LLC, BMO Capital Markets Corp. and National Bank of Canada Financial Inc. are affiliates of financial institutions which are lenders to the Corporation and/or certain subsidiary entities of the Corporation. Consequently, the Corporation may be considered a connected issuer to each of the foregoing Underwriters for purposes of applicable Canadian securities laws.

PRESENTATION OF FINANCIAL INFORMATION

Unless otherwise indicated, all financial information included and incorporated by reference in this Prospectus Supplement has been prepared in accordance with Generally Accepted Accounting Principles in the United States.

NON-GAAP FINANCIAL MEASURES

The terms “Adjusted Net Earnings”, “Adjusted Net Earnings per share” (or “Adjusted Net EPS”), “adjusted earnings before interest, taxes, depreciation and amortization” (“Adjusted EBITDA”) and “Adjusted Funds from Operations” may be used in this Prospectus and are not recognized measures under U.S. GAAP.

“Adjusted Net Earnings” is a non-GAAP 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 costs, 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 (other than those realized in connection with the sales of development assets), costs related to management succession and executive retirement, costs related to prior period adjustments due to the Tax Cuts and Jobs Act (“U.S. Tax Reform”), costs related to condemnation proceedings, financial impacts from the significantly elevated pricing that persisted in the Electric Reliability Council of Texas market over several days (the “Market Disruption Event”) on the Corporation’s Senate Wind Facility, changes in value of investments carried at fair value, and other typically non-recurring or unusual items as these are not reflective of the performance of the underlying business of the Corporation. The non-cash accounting charge related to the revaluation of U.S. deferred income tax assets and liabilities as a result of implementation of the effects of U.S. Tax Reform is adjusted as it is also considered a non-recurring item 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. The Corporation uses “Adjusted Net EPS” to enhance assessment and understanding of the performance of the Corporation. “Adjusted Net EPS” represents Adjusted Net Earnings less dividends on preferred shares divided by the weighted average number of Common Shares outstanding during the relevant period.

“Adjusted EBITDA” is a non-GAAP measure used by many investors to compare companies on the basis of ability to generate cash from operations. The Corporation uses these calculations to monitor the amount of cash generated by the Corporation. The Corporation uses Adjusted EBITDA to assess the operating performance of the Corporation without the effects of (as applicable): depreciation and amortization expense, income tax expense or recoveries, acquisition costs, certain litigation expenses, interest expense, gain or loss on derivative financial instruments, write down of intangibles and property, plant and equipment, earnings attributable to noncontrolling interests, non-service pension and post-employment costs, cost related to tax equity financing, costs related to management succession and executive retirement, costs related to prior period adjustments due to U.S. Tax Reform, costs related to condemnation proceedings, financial impacts from the Market Disruption Event on the Corporation’s Senate Wind Facility as a result of the February 2021 extreme winter storm conditions experienced in Texas and parts of the central U.S., gain or loss on foreign exchange, earnings or loss from discontinued operations, changes in value of investments carried at fair value, 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 EBITDA 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.

“Adjusted Funds from Operations” is a non-GAAP measure used by investors to compare cash flows from operating activities without the effects of certain volatile items that generally have no current economic impact or

items such as acquisition expenses that are viewed as not directly related to a company’s operating performance. The Corporation uses Adjusted Funds from Operations to assess its performance without the effects of (as applicable): changes in working capital balances, acquisition expenses, certain litigation expenses, cash provided by or used in discontinued operations, financial impacts from the Market Disruption Event on the Corporation’s Senate Wind Facility, and other typically non-recurring items affecting cash from operations as these are not reflective of the long-term performance of the underlying businesses of the Corporation. The Corporation believes that analysis and presentation of funds from operations on this basis will enhance an investor’s understanding of the operating performance of its businesses. Adjusted Funds from Operations is not intended to be representative of cash flows from operating activities as determined in accordance with U.S. GAAP, and can be impacted positively or negatively by these items.

There is no standardized measure of “Adjusted Net Earnings”, “Adjusted Net EPS”, “Adjusted EBITDA” or “Adjusted Funds from Operations” and 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. For further information regarding the terms “Adjusted Net Earnings”, “Adjusted Net EPS”, “Adjusted EBITDA” or “Adjusted Funds from Operations”, including a reconciliation of “Adjusted Net Earnings” to “Net Earnings”, a reconciliation of “Adjusted EBITA” to “Net Earnings” and a reconciliation of “Adjusted Funds from Operations” to “Cash Flows from Operating Activities”, being the most directly comparable U.S. GAAP measure for each such non-GAAP measure, see “Non-GAAP Financial Measures—Reconciliation of Adjusted Net Earnings to Net Earnings”, “Non-GAAP Financial Measures—Reconciliation of Adjusted EBITDA to Net Earnings” and “Non-GAAP Financial Measures—Reconciliation of Adjusted Funds from Operations to Cash Flows from Operating Activities” in the Corporation’s most recent annual and interim MD&A, each of which is incorporated by reference in this Prospectus and available on SEDAR at www.sedar.com and EDGAR (as defined herein) at www.sec.gov.

Acquisition of New York American Water Company, Inc.

On January 3, 2022, the Corporation announced that Liberty Utilities (Eastern Water Holdings) Corp., a wholly-owned subsidiary of the Corporation’s regulated utility operating subsidiary, Liberty Utilities Co. (“Liberty Utilities”), had successfully completed the previously-announced acquisition of New York American Water Company, Inc. (“New York American Water”) from American Water Works Company, Inc. for a purchase price of approximately $608 million. Headquartered in Merrick, New York, New York American Water is a regulated water and wastewater utility serving over 125,000 customer connections across seven counties in southeastern New York. New York American Water’s operations include approximately 1,270 miles of water mains and distribution lines, with 98% of customers in Nassau County on Long Island. The purchase price for the acquisition of New York American Water was funded through drawings on a $1.1 billion credit facility of Liberty Utilities entered into on December 20, 2021 (the “Liberty Utilities 2021 Credit Facility”).

Kentucky Power Acquisition

On October 26, 2021, Liberty Utilities entered into an agreement with American Electric Power Company, Inc. and AEP Transmission Company, LLC to acquire Kentucky Power and Kentucky TransCo for a total purchase price of approximately $2.846 billion, including the assumption of approximately $1.221 billion in debt.

Kentucky Power is a state rate-regulated electricity generation, distribution and transmission utility serving approximately 228,000 active customer connections in 20 eastern Kentucky counties and operating under a cost of service framework. Kentucky TransCo is an electricity transmission business operating in the Kentucky portion of the transmission infrastructure that is part of the Pennsylvania—New Jersey—Maryland regional transmission organization (PJM). Kentucky Power and Kentucky TransCo are both regulated by the U.S. Federal Energy Regulatory Commission (“FERC”).

Closing of the Kentucky Power Acquisition is subject to receipt of certain regulatory and governmental approvals, including the expiration or termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, clearance of the Kentucky Power Acquisition by the Committee on Foreign Investment in the United States, the approval by each of the Kentucky Public Service Commission and FERC, and the approval of the Public Service Commission of West Virginia with respect to the termination and replacement of the existing operating agreement for the Mitchell Plant (in which Kentucky Power owns a 50% interest, representing 780 MW), and the satisfaction of other customary closing conditions. If the acquisition agreement is terminated in certain circumstances, including due to a failure to receive required regulatory approvals (other than the approval of the Kentucky Public Service Commission, FERC or the Public Service Commission of West Virginia for the termination and replacement of the existing operating agreement for the Mitchell Plant), the Corporation may be required to pay a termination fee of $65 million. The Kentucky Power Acquisition is expected to close in mid-2022.

TABLE OF CONTENTS

SUMMARY

The following information is a summary only and is to be read in conjunction with, and is qualified in its entirety by, the more detailed information and financial data and statements appearing elsewhere in this Prospectus Supplement or the Base Shelf Prospectus and in the documents incorporated by reference herein. Reference is made to the “Description of the Notes” section of this Prospectus Supplement for the meaning of certain terms not otherwise defined in this section.

The Notes

Issuer:

Algonquin Power & Utilities Corp., a corporation formed under the Canada Business Corporations Act (the “Corporation” or “Algonquin”).

Offering:

$ aggregate principal amount of unsecured % Fixed-to-Fixed Reset Rate Junior Subordinated Notes Series 2022-B of the Corporation due , 2082 (the “Notes”).

Issue Date:

, 2022.

Maturity Date:

, 2082.

Specified Denominations:

Minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Use of Proceeds:

The net proceeds from this Offering will be $ , determined after deducting the underwriting commission but before accounting for any additional expenses of the Offering paid or payable by the Corporation.

The net proceeds to the Corporation from the Concurrent Canadian Offering (as defined herein) will be approximately C$ million (or $ million using the daily exchange rate as reported by the Bank of Canada on January , 2022 of C$1.00 = $ ) after deducting the underwriting commission but before deducting expenses of the Concurrent Canadian Offering. The expenses of the Concurrent Canadian Offering are estimated to be approximately C$ million and will be paid from the general funds of the Corporation.

The Corporation expects that the net proceeds of the Offering and the net proceeds of the Concurrent Canadian Offering will be used to partially finance the Kentucky Power Acquisition, provided that, in the short-term, prior to the closing of the Kentucky Power Acquisition, the Corporation expects to use such net proceeds to reduce amounts outstanding under existing credit facilities of the Corporation and its subsidiaries, which indebtedness was principally incurred in the ordinary course of operations and to fund the Corporation’s previously disclosed growth opportunities. See “Use of Proceeds” and “Underwriting.”

While the Corporation intends to use the net proceeds of the Offering as set out above, the Offering is not conditional upon the closing of the Kentucky Power Acquisition and management of the Corporation will have discretion concerning the use of proceeds of the Offering as well as the timing of such expenditures. See “Risk Factors.”

Further Issuance:

The Corporation may, without the consent of the holders of the Notes, “reopen” the Notes and issue additional notes from time to time in the future. The Notes offered hereby and any additional notes that the Corporation may issue by reopening such series of

S-11

TABLE OF CONTENTS

Notes will constitute a single series under the Indenture and will, in the circumstances in which the Indenture provides, vote or take any other action as a single class. See “Description of the Notes—Further Issuance.”

Interest:

The Notes will bear interest from, and including, the Issue Date to, but excluding, , 2027 at a rate of % per annum. On , 2027 and on every fifth anniversary of such date thereafter (each such date an “Interest Reset Date”), the interest rate on the Notes shall be reset, and the Notes will bear interest at a rate per annum equal to the Five-Year U.S. Treasury Rate on the business day immediately preceding such Interest Reset Date (each, an “Interest Rate Calculation Date”) plus, (i) for the period from, and including, , 2027 to, but excluding, , 2032, %, (ii) for the period from, and including, , 2032 to, but excluding, , 2052, % and (iii) for the period from, and including, , 2052 to, but excluding, the Maturity Date, %, in each case, to be reset on each Interest Reset Date.

Deferral Right:

So long as no event of default has occurred and is continuing, the Corporation may elect, at its sole option, at any date other than an Interest Payment Date, to defer the interest payable on the Notes on one or more occasions for up to five consecutive years (a “Deferral Period”). There is no limit on the number of Deferral Periods that may occur. Such deferral will not constitute an event of default or any other breach under the Indenture and the Notes. Deferred interest will accrue, compounding on each subsequent Interest Payment Date, until paid. A Deferral Period terminates on any Interest Payment Date where the Corporation pays all accrued and unpaid interest on such date. No Deferral Period may extend beyond the Maturity Date, and for greater certainty, all accrued and unpaid interest shall be due and payable at maturity.

If the Corporation defers payments of interest on the Notes, the Notes will be treated at that time, solely for purposes of the original issue discount rules, as having been retired and reissued with original issue discount for United States federal income tax purposes. This means that if a holder is subject to United States federal income taxation on a net income basis, such holder would be required to include in such holder’s gross income for United States federal income tax purposes the deferred interest payments on such holder’s Notes before the receipt any cash, regardless of such holder’s regular method of accounting for United States federal income tax purposes. For more information concerning certain tax consequences if payments of interest are deferred, see “Risk Factors” and “Certain U.S. Federal Income Tax Considerations”.

Dividend Stopper Undertaking:

Unless the Corporation has paid all accrued and unpaid interest on the Notes, subject to certain exceptions, the Corporation will not (i) declare any dividends on the Dividend Restricted Shares or pay

S-12

TABLE OF CONTENTS

any interest on any Parity Notes, (ii) redeem, purchase or otherwise retire Dividend Restricted Shares or Parity Notes, or (iii) make any payment to holders of any of the Dividend Restricted Shares or any Parity Notes in respect of dividends not declared or paid on such Dividend Restricted Shares or interest not paid on such Parity Notes, respectively (the “Dividend Stopper Undertaking”).

“Dividend Restricted Shares” means, collectively, the preferred shares of the Corporation (including the Conversion Preferred Shares) and the Common Shares.

“Parity Notes” means any class or series of the Corporation’s indebtedness currently outstanding or hereafter created which ranks on a parity with the Notes (prior to any Automatic Conversion) as to distributions upon liquidation, dissolution or winding-up (including the Corporation’s 6.875% Fixed-to-Floating Subordinated Notes—Series 2018-A due October 17, 2078 and the Corporation’s 6.20% Fixed-to-Floating Subordinated Notes—Series 2019-A due July 1, 2079). Following completion of the Concurrent Canadian Offering (as defined herein), the Series 2022-A Notes (as defined herein) will also constitute Parity Notes.

It is in the interest of the Corporation to ensure that it timely pays interest on the Notes so as to avoid triggering the Dividend Stopper Undertaking. See “Description of the Notes—Dividend Stopper Undertaking” and “Risk Factors.”

Automatic Conversion:

The Notes, including accrued and unpaid interest (including deferred interest) thereon, will be converted automatically (the “Automatic Conversion”), without the consent of the holders thereof, into shares of a newly issued series of preferred shares of the Corporation (the “Conversion Preferred Shares”) upon the occurrence of: (i) the making by the Corporation of a general assignment for the benefit of its creditors or a proposal (or the filing of a notice of its intention to do so) under the Bankruptcy and Insolvency Act (Canada); (ii) any proceeding instituted by the Corporation seeking to adjudicate it as bankrupt (including any voluntary assignment in bankruptcy) or insolvent or, where the Corporation is insolvent, seeking liquidation, winding up, dissolution, reorganization, arrangement, adjustment, protection, relief or composition of its debts under any law relating to bankruptcy or insolvency in Canada, or seeking the entry of an order for the appointment of a receiver, interim receiver, trustee or other similar official for the Corporation or any substantial part of its property and assets in circumstances where the Corporation is adjudged as bankrupt (including any voluntary assignment in bankruptcy) or insolvent; (iii) a receiver, interim receiver, trustee or other similar official is appointed over the Corporation or for any substantial part of its property and assets by a court of competent jurisdiction in circumstances where the Corporation is adjudged as bankrupt (including any voluntary assignment in bankruptcy) or insolvent under any law relating to bankruptcy or insolvency in Canada; or (iv) any proceeding is instituted against the Corporation seeking to adjudicate it as bankrupt (including any voluntary assignment in bankruptcy) or insolvent, or where

S-13

TABLE OF CONTENTS

the Corporation is insolvent, seeking liquidation, winding up, dissolution, reorganization, arrangement, adjustment, protection, relief or composition of its debts under any law relating to bankruptcy or insolvency in Canada, or seeking the entry of an order for the appointment of a receiver, interim receiver, trustee or other similar official for the Corporation or any substantial part of its property and assets in circumstances where the Corporation is adjudged as bankrupt or insolvent under any law relating to bankruptcy or insolvency in Canada, and either such proceeding has not been stayed or dismissed within sixty (60) days of the institution of any such proceeding or the actions sought in such proceedings occur (including the entry of an order for relief against the Corporation or the appointment of a receiver, interim receiver, trustee, or other similar official for it or for any substantial part of its property and assets) (each, an “Automatic Conversion Event”).

The Automatic Conversion shall occur upon an Automatic Conversion Event (the “Conversion Time”). As of the Conversion Time, the Notes shall be automatically converted, without the consent of the holders of the Notes, into a newly issued series of fully-paid Conversion Preferred Shares. At such time, all outstanding Notes shall be deemed to be immediately and automatically surrendered and cancelled without need for further action by noteholders, who shall thereupon automatically cease to be holders thereof and all rights of any such holder as a debtholder of the Corporation shall automatically cease. At the Conversion Time, holders of the Notes will receive one Conversion Preferred Share for each $1,000 principal amount of Notes previously held together with the number of Conversion Preferred Shares (including fractional shares, if applicable) calculated by dividing the amount of accrued and unpaid interest (including deferred interest), if any, on the Notes, by $1,000.

Upon an Automatic Conversion of the Notes, the Corporation reserves the right not to issue some or all, as applicable, of the Conversion Preferred Shares to any person whose address is in, or whom the Corporation or its transfer agent has reason to believe is a resident of, any jurisdiction outside of Canada and the U.S. to the extent that: (i) the issuance or delivery by the Corporation to such person, upon an Automatic Conversion, of Conversion Preferred Shares, would require the Corporation to take any action to comply with securities or analogous laws of such jurisdiction; or (ii) withholding tax would be applicable in connection with the delivery to such person of Conversion Preferred Shares upon an Automatic Conversion (“Ineligible Persons”). In such circumstances, the Corporation will hold all Conversion Preferred Shares that would otherwise be delivered to Ineligible Persons, as agent for Ineligible Persons, and will attempt to facilitate the sale of such shares through a registered broker or dealer retained by the Corporation for the purpose of effecting the sale (to parties other than the Corporation, its affiliates or other Ineligible Persons) on behalf of such Ineligible Persons of such Conversion Preferred Shares. There can be no assurance that the Corporation will be successful in such attempts.

S-14

TABLE OF CONTENTS

As the events that give rise to an Automatic Conversion are bankruptcy and related events, it is in the interest of the Corporation to ensure that an Automatic Conversion does not occur, although the events that could give rise to an Automatic Conversion may be beyond the Corporation’s control. See “Description of the Notes—Automatic Conversion,” “Description of the Conversion Preferred Shares” and “Risk Factors.”

Optional Redemption Right:

A “Par Call Period” means the period from, and including, the immediately preceding an Interest Reset Date to, and including, that particular Interest Reset Date.

At any time not during a Par Call Period, the Corporation may, at its option, on giving not more than 60 days’ nor less than 30 days’ prior notice to the holders, redeem the Notes, in whole at any time or in part from time to time, at a redemption price equal to the greater of (i) 100.00% of the principal amount of the Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on such Notes (not including any portion of such payments of interest accrued as of the date fixed for redemption) that would be due if the Notes matured on the first day of the next succeeding Par Call Period, discounted to the date fixed for redemption (assuming a 360-day year comprising twelve 30-day months) at the Treasury Rate (as defined herein) plus 50 basis points and on a semi-annual basis; plus, in each case, accrued and unpaid interest (including deferred interest, if any) thereon to, but excluding, the date fixed for redemption.

Notice of any redemption of Notes may, at the Corporation’s discretion, be given subject to one or more conditions precedent, including, but not limited to, completion of a corporate transaction that is pending (such as an equity or equity-linked offering, an incurrence of indebtedness or an acquisition or other strategic transaction involving a change of control of the Corporation or another entity). If such redemption is so subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or otherwise waived on or prior to the business day immediately preceding the relevant redemption date.

In the event that the Corporation redeems or purchases any of the Notes, the Corporation intends (without thereby assuming a legal obligation) to do so only to the extent the aggregate redemption or purchase price is equal to or less than the net proceeds, if any, received by the Corporation from new issuances during the period commencing on the 360th calendar day prior to the date of such

S-15

TABLE OF CONTENTS

redemption or purchase of securities which are assigned by S&P (as defined herein) at the time of sale or issuance, an aggregate equity credit that is equal to or greater than the equity credit assigned to the Notes to be redeemed or purchased (but taking into account any changes in hybrid capital methodology or another relevant methodology or the interpretation thereof since the issuance of the Notes), unless the Notes are redeemed pursuant to a Rating Event (to the extent it is triggered by a change of methodology at S&P) or a Tax Event.

Redemption on Tax Event or Rating Event:

After the occurrence of a Tax Event, the Corporation may, at its option, redeem all (but not less than all) of the Notes. The redemption price per $1,000 principal amount of Notes will be equal to 100.00% of the principal amount thereof, together with accrued and unpaid interest (including deferred interest, if any) thereon to, but excluding, the date fixed for redemption. See “Description of the Notes—Redemption on Tax Event or Rating Event.”

At any time within 120 days following the occurrence of a Rating Event, the Corporation may, at its option, redeem all (but not less than all) of the Notes. The redemption price per $1,000 principal amount of Notes will be equal to 102.00% of the principal amount thereof, together with accrued and unpaid interest (including deferred interest, if any) thereon to, but excluding, the date fixed for redemption. See “Description of the Notes—Redemption on Tax Event or Rating Event.”

Purchase for Cancellation:

Subject to the Dividend Stopper Undertaking, the Notes may be purchased, in whole or in part, by the Corporation in the open market or by tender or private contract. Notes purchased by the Corporation shall be cancelled and shall not be reissued. The purchase price payable by the Corporation will be paid in cash. See “Description of the Notes—Purchase for Cancellation.”

Additional Algonquin Covenants:

In addition to the Dividend Stopper Undertaking, the Corporation will covenant for the benefit of the holders of the Notes that it will not create or issue any Issuer Preferred Shares which, in the event of insolvency or winding-up of the Corporation, would rank in right of payment in priority to the Conversion Preferred Shares. See “Description of the Notes—Additional Covenants.”

Subordination and Events of Default:

The Notes will be direct unsecured subordinated obligations of the Corporation. The payment of principal and interest on the Notes will be subordinated in right of payment to the prior payment in full of all present and future Senior Indebtedness, and will be effectively subordinated to all indebtedness and obligations of the Corporation’s subsidiaries.

Indebtedness) of, or guaranteed or assumed by, the Corporation for borrowed money or evidenced by bonds, debentures or notes or obligations of the Corporation for or in respect of bankers’ acceptances (including the face amount thereof), letters of credit and letters of guarantee (including all reimbursement obligations in respect of each of the foregoing) or other similar instruments, and amendments, renewals, extensions, modifications and refunding of any such indebtedness or obligation. As of September 30, 2021, the Corporation’s Senior Indebtedness (excluding undrawn letters of credit) totaled approximately $1.17 billion.

In addition, as of September 30, 2021, the total long-term indebtedness of the Corporation’s subsidiaries was approximately $5.08 billion (including securities due within one year).

An event of default in respect of the Notes will occur only if the Corporation defaults (i) on the payment of principal or premium or Additional Amounts, if any, when due and payable, (ii) on the payment of interest (including Additional Amounts) when due and payable and such default continues for 30 days (provided, however, that if the Corporation, at its sole option, elects to defer interest payments as described under “Description of the Notes—Deferral Right”, the date on which such payment is due and payable shall be the date on which the Corporation is required to make payment following such deferral), (iii) in the performance of the covenant described under the caption “—Merger, Amalgamation, Consolidation, Sale, Lease or Conveyance”, or (iv) in the performance of, or breaches, any covenant of the Corporation under the Indenture (other than a covenant or a default in whose performance or breach is specifically dealt with in clauses (i), (ii) or (iii) above), and such default or breach continues for a period of 90 days after there has been given written notice to the Corporation by either Trustee (with a copy to the other Trustee), or to the Corporation and the Trustees by the holders of at least 25% in principal amount of the Notes, specifying such default or breach and requiring it to be remedied.

If an event of default has occurred and is continuing, and the Notes have not already been automatically converted into Conversion Preferred Shares, then the Corporation shall without notice from a Trustee be deemed to be in default under the Indenture and the Notes and the U.S. Trustee may, in its discretion and shall upon the request of holders of not less than 25% of the principal amount of Notes then outstanding under the Indenture, demand payment of the principal or premium or Additional Amounts, if any, together with any accrued and unpaid interest (including Additional Amounts) up to (but excluding) such date, which shall immediately become due and payable in cash, and may institute legal proceedings for the collection of such aggregate amount where the Corporation fails to make payment thereof upon such demand.

Payment of Additional Amounts:

All payments made by or on account of any obligation of the Corporation under or with respect to the Notes shall be made free and clear of and without withholding or deduction for, or on account of, any present or future Taxes, unless the Corporation is

S-17

TABLE OF CONTENTS

required to withhold or deduct Taxes by law or by the interpretation or administration thereof by the relevant government authority or agency. If the Corporation is so required to withhold or deduct any Taxes imposed by the Government of Canada or any province or territory thereof or by any authority or agency therein or thereof having power to tax (a “Relevant Taxing Jurisdiction,” and such Taxes, “Canadian Taxes”) from any payment made under or with respect to the Notes, the Corporation shall pay as additional interest such additional amounts (hereinafter “Additional Amounts”), as may be necessary so that the net amount received by each holder of the Notes (including Additional Amounts) after such withholding or deduction for Canadian Taxes shall not be less than the amount the holder of the Notes would have received if such Canadian Taxes had not been withheld or deducted, subject to certain exceptions. See “Description of the Notes—Payment of Additional Amounts.”

Book-Entry Only Form:

The Underwriters expect to deliver the Notes on or about January , 2022 in book-entry form through The Depository Trust Company and its direct and indirect participants (each, a “Participant”), including Euroclear Bank S.A./N.V. and Clearstream Banking S.A. Accordingly, physical certificates representing the Notes will not be available except in the limited circumstances described under “Description of the Notes—Book-Entry Only Form.”

Conversion Preferred Shares:

Holders of the Conversion Preferred Shares will be entitled to receive cumulative preferential cash dividends if, as and when declared by the Board of Directors, subject to the solvency test set out in the Canada Business Corporations Act or any other applicable law at the same rate as would have accrued on the Notes (had the Notes remained outstanding) as described under “Description of the Notes—Interest and Maturity” (the “Perpetual Preferred Share Rate”), payable on each semi-annual dividend payment date, subject to any applicable withholding tax. See “Description of the Conversion Preferred Shares.”

Concurrent Canadian Offering

Absence of Trading Market:

The Notes constitute a new issue of securities with no established trading market. The Corporation does not intend to apply for listing of the Notes on any securities exchange and, consequently, purchasers may not be able to resell the Notes purchased under this Prospectus Supplement.

Risk Factors:

S-18

TABLE OF CONTENTS

RISK FACTORS

An investment in the Notes is subject to certain risks. In addition to the risks described herein, reference is made to the section in the AIF under the heading “Enterprise Risk Factors” and in the Corporation’s most recent annual and interim MD&A under the heading “Enterprise Risk Management” and to the risks disclosed in other documents incorporated by reference herein. Such risk factors could have a materially adverse effect on the future results of operations, business prospects or financial condition of the Corporation, and could cause actual events to differ materially from those described in forward-looking information. Additional risks and uncertainties not presently known to the Corporation, or which the Corporation currently deems to be immaterial, may also have an adverse effect upon the Corporation.

Risks Relating to the Offering

Discretion in the Use of Proceeds

The Corporation intends to use the net proceeds of this Offering and the net proceeds of the Concurrent Canadian Offering to fund a portion of the purchase price for the Kentucky Power Acquisition as described under “Use of Proceeds”; however, neither the Offering nor the Concurrent Canadian Offering is conditional upon the closing of the Kentucky Power Acquisition and management of the Corporation will have discretion concerning the use of proceeds of the Offering and the Concurrent Canadian Offering as well as the timing of their expenditures. As a result, investors will be relying on the judgment of management as to the application of the proceeds of the Offering. Management may use the net proceeds of the Offering and the Concurrent Canadian Offering in ways that an investor may not consider desirable. The results and effectiveness of the application of the proceeds are uncertain. If the proceeds are not applied effectively, the Corporation’s results of operations may suffer.

The Concurrent Canadian Offering May Not be Completed

Completion of the Offering is not conditional on the completion of the Concurrent Canadian Offering, and closing of the Offering may occur in circumstances where the Concurrent Canadian Offering is not completed. Accordingly, there can be no certainty, nor can the Corporation provide any assurance, that the Concurrent Canadian Offering will be completed.

Risk of Credit Rating Downgrade

The change in the capital structure of the Corporation as a result of the Kentucky Power Acquisition and the related financing plan, including the incurrence of additional indebtedness represented by this Offering, the Concurrent Canadian Offering or otherwise, could cause credit rating agencies which rate the Corporation’s outstanding debt obligations to re-evaluate and potentially downgrade the Corporation’s current credit ratings, which could increase the Corporation’s borrowing costs and adversely impact the market price of the outstanding securities of the Corporation, including the Notes. See “Liquidity and Capital Reserves—Credit Ratings” in the Corporation’s most recent interim MD&A.

The Kentucky Power Acquisition could also result in a downgrade of the credit rating of Kentucky Power or its outstanding bonds, and could require Kentucky Power to offer to prepay $525 million in principal amount of its outstanding bonds if the credit ratings thereof fall below investment grade (or in the event such bonds are placed on “credit watch” or assigned a “negative outlook” if they are rated BBB− by S&P or Baa3 by Moody’s Investors Services, Inc. at such time).

Risks Relating to the Notes

Rights only as an Equity Holder in the Event of Insolvency

In the event of the occurrence of the Automatic Conversion, with the result that the holder of Notes receives Conversion Preferred Shares on conversion of such Notes, the only claim or entitlement of such holder will be in its capacity as a shareholder of the Corporation. See “Description of the Notes—Automatic Conversion” and “Risks Relating to the Conversion Preferred Shares—Insolvency or Winding-Up.”

Market for the Notes

The Notes constitute a new issue of securities with no established trading market. In addition, it is not expected that the Notes will be listed on any securities exchange or quotation system. As a result, the trading market for the

S-19

TABLE OF CONTENTS

Notes may not be active or liquid and purchasers may not be able to resell the Notes purchased under this Prospectus Supplement. This may affect the trading prices of the Notes in the secondary market, the transparency and availability of trading prices, and the liquidity of the Notes.

The price offered to the public for the Notes was determined through negotiations with the Underwriters. If the Notes are traded after their initial issuance, they may trade at a discount from their initial issuance price depending on prevailing interest rates, the market for similar securities, the performance of the Corporation and other factors. There can be no assurance that an active trading market will develop or be sustained or that the Notes may be resold at or above the initial public offering price. In addition, the ability of a holder to pledge Notes or otherwise take action with respect to such holder’s interest in Notes (other than through a Participant) may be limited due to the lack of a physical certificate.

Subordination

The Corporation’s obligations under the Notes will be subordinated in right of payment to all of the Corporation’s current and future Senior Indebtedness. This means that the Corporation will not be permitted to make any payments on the Notes if it defaults on a payment of principal of, premium, if any, or interest on any such Senior Indebtedness or there shall occur an event of default under such Senior Indebtedness and it does not cure the default within the applicable grace period, if the holders of the Senior Indebtedness have the right to accelerate the maturity of such indebtedness or if the terms of such Senior Indebtedness otherwise restrict the Corporation from making payments to junior creditors. See “Description of the Notes—Subordination.”

In addition to the contractual subordination described above, the Notes will not be guaranteed by the Corporation’s subsidiaries and, as a result, payment of principal of, premium, if any, and interest on the Notes will be structurally subordinated to any indebtedness and other liabilities of the Corporation’s subsidiaries.

As of September 30, 2021, (i) the Corporation on a consolidated basis had approximately $6.87 billion of outstanding indebtedness (excluding undrawn letters of credit), of which approximately $1.17 billion was Senior Indebtedness of the Corporation on a standalone basis (excluding undrawn letters of credit); and (ii) the total long-term indebtedness of the Corporation’s subsidiaries was approximately $5.08 billion (including securities due within one year). All such indebtedness will effectively rank senior to the Notes.

Furthermore, in the event of an insolvency or liquidation of the Corporation, the claims of creditors of the Corporation would be entitled to a priority payment over the claims of holders of equity interests of the Corporation, such as the Conversion Preferred Shares. See “Risk Factors—Risks Relating to the Notes—Rights only as an Equity Holder in the Event of Insolvency” and “Risk Factors—Risks Relating to the Conversion Preferred Shares— Insolvency or Winding-up.”

No Limit on Debt

The Indenture does not contain any provision limiting the Corporation’s ability to incur indebtedness generally. Any such indebtedness could rank in priority to the Notes. The Corporation currently has substantial indebtedness and may incur substantial additional indebtedness in the future, including as a result of the Kentucky Power Acquisition.

Early Redemption

The Corporation may redeem the Notes in the circumstances described under “Description of the Notes—Optional Redemption Right,” and “Description of the Notes—Redemption on Tax Event or Rating Event.” This redemption right may, depending on prevailing market conditions at the time, create reinvestment risk for holders of the Notes in that they may be unable to find a suitable replacement investment with a comparable return to the Notes.

Deferral Right

So long as no event of default has occurred and is continuing, subject to certain exceptions, the Corporation may elect, at its sole option, to defer the interest payable on the Notes on one or more occasions for up to five consecutive years as described under “Description of the Notes—Deferral Right.” There is no limit on the number of Deferral Periods that may occur. Such deferral will not constitute an event of default or any other breach under the Notes and the Indenture.

S-20

TABLE OF CONTENTS

Investors in the Notes located outside of Canada may have difficulties enforcing civil liabilities

The Corporation is incorporated under the laws of Canada and its registered and head office is in Canada. Most of the Corporation’s officers and some of the Corporation’s directors, and some of the experts named in this Prospectus Supplement, are residents of Canada or otherwise reside outside of the United States, and a portion of their assets, and a portion of the Corporation’s assets, are located outside the U.S. The Corporation will agree, in accordance with the terms of the Indenture, to accept service of process in any suit, action or proceeding with respect to the Indenture or the Notes brought in any federal or state court located in New York City by an agent designated for such purpose, and to submit to the jurisdiction of such courts in connection with such suits, actions or proceedings. Nevertheless, it may be difficult for holders of the Notes to effect service of process within the United States upon directors, officers and experts who are not residents of the United States or to realize in the United States upon judgments of courts of the United States predicated upon civil liability under U.S. federal or state securities laws or other laws of the United States. The Corporation has been advised by its Canadian counsel, Blake, Cassels & Graydon LLP, that a judgment of a U.S. court predicated solely upon civil liability under U.S. federal securities laws would probably be enforceable in Canada if the United States court in which the judgment was obtained has a basis for jurisdiction in the matter that would be recognized by a Canadian court for the same purposes. The Corporation has also been advised by Blake, Cassels & Graydon LLP, however, that there is a substantial doubt whether an action could be brought in Canada in the first instance on the basis of liability predicated solely upon U.S. federal securities laws.

The interest rate will reset on , 2027 and each subsequent Interest Reset Date, and any interest payable after an Interest Rate Date may be less than an earlier interest rate

The Notes will bear interest from, and including, the Issue Date to, but excluding, , 2027 at a rate of % per annum. On , 2027 and on every Interest Reset Date thereafter, the interest rate on the Notes shall be reset, and the Notes will bear interest at a rate per annum equal to the Five-Year U.S. Treasury Rate on the Interest Rate Calculation Date in respect of such Interest Reset Date plus, (i) for the period from, and including, , 2027 to, but excluding, , 2032, %, (ii) for the period from, and including, , 2032 to, but excluding, , 2052, % and (iii) for the period from, and including, , 2052 to, but excluding, the Maturity Date, %, in each case, to be reset on each Interest Reset Date. Therefore, the interest rate after , 2027 could be less than the initial interest rate applicable to the Notes, and any interest payable after a subsequent Interest Reset Date may be less than the interest rate for a prior period. The Corporation has no control over the factors that may affect United States Treasury rates, including geopolitical conditions and economic, financial, political, regulatory, judicial or other events.

Historical United States Treasury rates are not an indication of future United States Treasury rates

In the past, United States Treasury rates have experienced significant fluctuations. Historical levels, fluctuations and trends of United States Treasury rates are not necessarily indicative of future levels. Any historical upward or downward trend in United States Treasury rates is not an indication that United States Treasury rates are more or less likely to increase or decrease at any time after , 2027, and historical United States Treasury rates are not an indication of future Five-Year U.S. Treasury Rates.

The tax treatment of the Notes for U.S. federal income tax purposes is uncertain

The treatment of the Notes for U.S. federal income tax purposes is uncertain. The determination of whether an instrument is properly treated as indebtedness or equity for U.S. federal income tax purposes is based on all the relevant facts and circumstances. There is no statutory, judicial or administrative authority directly addressing the U.S. federal income tax treatment of an instrument with substantially identical terms as the Notes. In the absence of authority directly addressing the proper treatment of instruments such as the Notes, to the extent required to do so, the Corporation intends to treat the Notes as debt for U.S. federal income tax purposes. However, the Corporation will not request any ruling from the IRS (as defined herein), regarding the treatment of the Notes for U.S. federal income tax purposes and the IRS or a court may conclude that the Notes should be treated as equity for U.S. federal income tax purposes.

If the Notes were treated as equity for U.S. federal income tax purposes and the Corporation were a PFIC (as defined herein) for any taxable year during which a U.S. investor held the Notes, the U.S. investor could be subject to adverse tax consequences, including increased tax liability on certain gains and payments on the Notes and a

S-21

TABLE OF CONTENTS

requirement to file annual reports with the IRS. The Corporation does not expect to be a PFIC for its 2022 taxable year. However, the determination of whether the Corporation is a PFIC is based on the application of complex U.S. federal income tax rules, which are subject to differing interpretations, and will depend on the composition of the Corporation’s income and assets from time to time and the nature of its activities. PFIC classification is factual in nature, and generally cannot be determined until the close of the taxable year in question. Consequently, there can be no assurances regarding the Corporation’s PFIC status for its current or any future taxable year.

Prospective investors should consult their tax advisers as to the proper characterization of the Notes for U.S. federal income tax purposes and the consequences of holding a Note if the Corporation is or becomes a PFIC. See “Certain U.S. Federal Income Tax Considerations.”

If the possibility of interest deferral were determined not to be remote, or if interest payments on the Notes are in fact deferred, U.S. investors would be required to recognize income for U.S. federal income tax purposes in advance of the receipt of cash attributable to such income

In the event the possibility of interest deferral were determined not to be remote under applicable U.S. Treasury regulations, or if the Corporation in fact exercises its option to defer payments of interest, the Notes would be treated as issued with OID at the time of issuance, or at the time of deferral, as the case may be, and all stated interest, or if interest is in fact deferred, all stated interest due after such deferral, would be treated as original issue discount for U.S. federal income tax purposes (“OID”). Consequently, a U.S. investor would be required to include interest income as it accrues using a constant yield method, regardless of such investor’s method of accounting, and before such investor receives any payment attributable to such income. The calculation of the amount of such accruals may be complex, and therefore U.S. investors should consult their tax advisers regarding the tax consequences if the Notes were treated as issued (or deemed reissued) with OID. See “Certain U.S. Federal Income Tax Considerations.”

Rating agencies may change their practices for rating the Notes, which change may affect the market price of the Notes. In addition, the Corporation may redeem the Notes if a rating agency makes certain changes in the equity credit methodology for securities such as the Notes.

The rating agencies that currently or may in the future publish a rating for the Corporation, including S&P (as defined herein) and Fitch (as defined herein) may, from time to time in the future, change the way they analyze securities with features similar to the Notes. This may include, for example, changes to the relationship between ratings assigned to an issuer’s senior securities and ratings assigned to securities with features similar to the Notes. If the rating agencies change their practices for rating these types of securities in the future, and the ratings of the Notes are subsequently lowered, that could have a negative impact on the trading price of the Notes. In addition, the Corporation may redeem the Notes at its option, in whole, but not in part, if a rating agency makes certain changes in the equity credit methodology for securities such as the Notes. See “Description of the Notes—Redemption on Tax Event or Rating Event” in this Prospectus Supplement.

Risks Relating to the Conversion Preferred Shares

Dividends

Holders of Conversion Preferred Shares do not have a right to dividends on such shares unless declared by the Board of Directors. The declaration of dividends is in the discretion of the Board of Directors even if the Corporation has sufficient funds, net of its liabilities, to pay such dividends. The Corporation may not declare or pay a dividend if there are reasonable grounds for believing that (i) the Corporation is, or would after the payment be, unable to pay its liabilities as they become due, or (ii) the realizable value of the Corporation’s assets would thereby be less than the aggregate of its liabilities and stated capital of its outstanding shares. Liabilities of the Corporation will include those arising in the course of its business, indebtedness, including inter-company debt, and amounts, if any, that are owing by the Corporation under guarantees in respect of which a demand for payment has been made. In addition, a dividend (including a deemed dividend) received on Conversion Preferred Shares may be subject to Canadian non-resident withholding tax and, if any such dividends are so subject, no additional amounts will be payable to holders of Conversion Preferred Shares in respect of such withholding tax. See “Certain Canadian Federal Income Tax Considerations—Conversion Preferred Shares—Dividends.”

Credit ratings applied to the Notes and the Conversion Preferred Shares may affect the market price or value and the liquidity of the Notes and Conversion Preferred Shares

The credit ratings applied to the Notes and the Conversion Preferred Shares issuable on conversion of the Notes are an assessment by the Rating Agencies (as defined herein) of the Corporation’s ability to pay its obligations. The

S-22

TABLE OF CONTENTS

credit ratings are based on certain assumptions about the future performance and capital structure of the Corporation that may or may not reflect the actual performance or capital structure of the Corporation. Changes in credit ratings of the Notes and the Conversion Preferred Shares issuable on conversion of the Notes may affect the market price or value and the liquidity of the Notes and Conversion Preferred Shares. There is no assurance that any credit rating assigned to the Notes or the Conversion Preferred Shares will remain in effect for any given period of time or that any rating will not be lowered or withdrawn entirely by the relevant Rating Agency.

Insolvency or Winding-Up

The Conversion Preferred Shares do not constitute indebtedness and are equity capital of the Corporation which rank junior to all indebtedness and other non-equity claims and equally with the other outstanding series of the Corporation’s preferred shares in the event of an insolvency or winding-up of the Corporation. If the Corporation becomes insolvent or is wound up, the Corporation’s assets must be used to pay liabilities and other debt before payments may be made on the Conversion Preferred Shares and other preferred shares of the Corporation, if any.

No Fixed Maturity

The Conversion Preferred Shares do not have a fixed maturity date and are not redeemable at the option of the holders of the Conversion Preferred Shares. The ability of a holder to liquidate its holdings of Conversion Preferred Shares may be limited.

The Corporation may choose to redeem the Conversion Preferred Shares from time to time

The Corporation may choose to redeem the Conversion Preferred Shares from time to time, in accordance with its rights described under “Description of the Conversion Preferred Shares—Redemption of the Conversion Preferred Shares.” The amount payable upon redemption may be subject to withholding tax. In addition, if prevailing interest rates are lower at the time of redemption, a purchaser would not be able to reinvest the redemption proceeds in a comparable security at an effective yield as high as the yield on the Conversion Preferred Shares being redeemed. The Corporation’s redemption right also may adversely impact a purchaser’s ability to sell the Conversion Preferred Shares.

Voting Rights

Holders of Conversion Preferred Shares will not have any voting rights except in the event of the non-payment of four semi-annual dividends, subject to certain constraints, as described under “Description of the Conversion Preferred Shares—Voting Rights,” or otherwise required by law.

Secondary Market and Liquidity

There is currently no market through which the Conversion Preferred Shares may be sold and purchasers of Notes that are subsequently converted into Conversion Preferred Shares may not be able to resell the Conversion Preferred Shares. There can be no assurance that an active trading market will develop for the Conversion Preferred Shares following any issuance of those shares, or if developed, that such a market will be liquid or sustained at the issue price of such shares. The Corporation is under no obligation to list the Conversion Preferred Shares on any stock exchange or other market. The ability of a holder to pledge Conversion Preferred Shares or otherwise take action with respect to such holder’s interest therein (other than through a Participant) may be limited due to the lack of a physical certificate. The public offering price for the Notes and the principal amount of Notes to be issued have been determined by negotiations among the Corporation and the Underwriters. The price paid for each Note may bear no relationship to the price at which the Conversion Preferred Shares issuable on conversion of the Notes may trade subsequent to this Offering.

Market Value

The market value of the Conversion Preferred Shares may fluctuate due to a variety of factors relative to the Corporation’s business, including announcements of new developments, fluctuations in the Corporation’s operating results, sales of the Corporation’s preferred shares or other securities, failure to meet analysts’ expectations, the impact of various tax laws or rates and general market conditions or the worldwide economy. There can be no assurance that the market value of the Conversion Preferred Shares will not experience significant fluctuations in the future, including fluctuations that are unrelated to the Corporation’s performance. Prevailing yields on similar

S-23

TABLE OF CONTENTS

securities will affect the market value of the Conversion Preferred Shares. Assuming all other factors remain unchanged, the market value of the Conversion Preferred Shares would be expected to decline as prevailing yields for similar securities rise and would be expected to increase as prevailing yields for similar securities decline. Spreads over the Five-Year U.S. Treasury Rate and comparable benchmark rates of interest for similar securities will also affect the market value of the Conversion Preferred Shares in an analogous manner. In addition, the market value of the Conversion Preferred Shares will be significantly adversely affected in the event that dividends are not paid on such shares. See “Risks Relating to the Conversion Preferred Shares—Dividends.”

S-24

TABLE OF CONTENTS

USE OF PROCEEDS

The net proceeds to the Corporation from the Offering, after deducting the underwriting commission but before accounting for any additional expenses of the Offering paid or payable by the Corporation, will be approximately $ . Total expenses of the Offering, including the underwriting commission, are estimated to be approximately $ . See “Underwriting.”

The net proceeds to the Corporation from the Concurrent Canadian Offering will be approximately C$ million (or $ million using the daily exchange rate as reported by the Bank of Canada on January , 2022 of C$1.00 = $ ) after deducting the underwriting commission but before deducting expenses of the Concurrent Canadian Offering. The expenses of the Concurrent Canadian Offering are estimated to be approximately C$ million and will be paid from the general funds of the Corporation.

The Corporation expects that the net proceeds of the Offering and the net proceeds of the Concurrent Canadian Offering will be used to partially finance the Kentucky Power Acquisition, provided that, in the short-term, prior to the closing of the Kentucky Power Acquisition, the Corporation expects to use such net proceeds to reduce amounts outstanding under existing credit facilities (which indebtedness was principally incurred in the ordinary course of operations and to fund the Corporation’s previously disclosed growth opportunities) as follows: (i) approximately $ to the Corporation’s credit facility; (ii) approximately $ to the credit facility; and (iii) approximately $ to the credit facility.

While the Corporation intends to use the net proceeds as set out above, the Offering is not conditional upon the closing of the Kentucky Power Acquisition and management of the Corporation will have discretion concerning the use of proceeds of the Offering as well as the timing of such expenditures. See “Risk Factors.”

CONSOLIDATED CAPITALIZATION

The following table sets forth the unaudited consolidated capitalization of the Corporation as at September 30, 2021, and the unaudited pro forma consolidated capitalization of the Corporation as at September 30, 2021 after giving effect to: (i) the net proceeds of the bought deal Common Share offering announced concurrently with the Kentucky Power Acquisition (the “Bought Deal Offering”) of approximately $618 million; (ii) the short-term application of the net proceeds of the Bought Deal Offering, prior to the closing of the Kentucky Power Acquisition, to reduce amounts outstanding under the existing credit facilities of the Corporation and its subsidiaries; (iii) the net proceeds of the Offering, determined after deducting the Underwriters’ fee and estimated expenses of the Offering on an after-tax basis; (iv) the net proceeds of the Concurrent Canadian Offering determined after deducting the underwriters’ fee and estimated expenses of the Concurrent Canadian Offering on an after-tax basis; (v) the short-term application of the net proceeds of the Offering, prior to the closing of the Kentucky Power Acquisition, to reduce amounts outstanding under the existing credit facilities of the Corporation and its subsidiaries; (vi) the short-term application of the net proceeds of the Concurrent Canadian Offering, prior to the closing of the Kentucky Power Acquisition, to reduce amounts outstanding under the existing credit facilities of the Corporation and its subsidiaries; and (vii) drawings of $610.4 million on the Liberty Utilities 2021 Credit Facility to fund the purchase price and certain transaction expenses relating to the acquisition of New York American Water.

EARNINGS COVERAGE RATIOS

The following consolidated earnings coverage ratios are calculated for the 12-month periods ended September 30, 2021 and December 31, 2020. The ratios give effect to the distribution of $ principal amount of Notes offered pursuant to this Prospectus Supplement, the distribution of C$ principal amount of Series 2022-A Notes offered pursuant to the Concurrent Canadian Offering and the repayment of certain indebtedness outstanding during such periods if such issuance and repayments had occurred on October 1, 2020 and January 1, 2020, respectively. The Corporation’s borrowing cost requirements after giving effect to the issue of the Notes, the issue of the Series 2022-A Notes¹ and the repayment of certain indebtedness outstanding during such periods (including the indebtedness to be repaid using the net proceeds of the Offering and the Concurrent Canadian Offering, see “Use of Proceeds”) amounted to $ million and $ million for the 12 months ended December 31, 2020 and the 12 months ended September 30, 2021, respectively.

Algonquin, a corporation organized and existing under the laws of Canada, will issue $ aggregate principal amount of % Fixed-to-Fixed Reset Rate Junior Subordinated Notes Series 2022-B due , 2082 (the “Notes”) under an indenture, dated as of October 17, 2018 (the “Base Indenture”), among the Issuer, American Stock Transfer & Trust Company, LLC, as the United States trustee, paying agent, registrar and transfer agent (the “U.S. Trustee”) and TSX Trust Company (as successor to AST Trust Company (Canada)), as the Canadian trustee (the “Canadian Co-Trustee”), as supplemented by the third supplemental indenture, to be dated as of the Issue Date (the “Third Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), among the Issuer, the U.S. Trustee and the Canadian Co-Trustee.

The following is a summary of the material rights, privileges, restrictions, obligations and conditions attaching to the Notes and certain provisions of the Indenture and is intended to supplement, and to the extent inconsistent, to replace, the more general terms and provisions of the debt securities described in the accompanying Base Shelf Prospectus, to which we refer you. This summary is qualified in its entirety by the provisions of the Indenture and the Notes. You should read the Indenture and the Notes in their entirety. Copies of the Indenture and the Notes may be obtained upon request to the Issuer at the address set forth under “Documents Incorporated by Reference.”

For information concerning the Conversion Preferred Shares into which the Notes are, in certain circumstances, convertible as described under “—Automatic Conversion” below, see “Description of the Conversion Preferred Shares.”

In this “Description of the Notes” section (i) references to the “Issuer” or “we” refers only to Algonquin Power & Utilities Corp. and not any of its subsidiaries and (ii) the U.S. Trustee and the Canadian Co-Trustee are each also individually referred to as a “Trustee” and collectively as the “Trustees.” Unless otherwise indicated, defined terms used in this section apply only to this “Description of the Notes” section and the “Description of the Conversion Preferred Shares” section and not to any other sections of this Prospectus Supplement.

Further Issuance

The Notes will constitute a separate series of Securities (as defined in the Base Indenture) under the Indenture, initially limited to $ in aggregate principal amount. Under the Indenture the Issuer may, without the consent of the holders of the Notes, “reopen” the series of Securities of which the Notes are a part and issue additional notes of such series from time to time in the future. The Notes offered by this Prospectus Supplement and any additional notes of such series that the Issuer may issue in the future will constitute a single series of Securities under the Indenture. This means that, in circumstances in which the Indenture provides for the holders of Securities of any series to vote or take any other action as a single class, the Notes offered hereby and any additional notes of such series of notes that the Issuer may issue by reopening such series will vote or take that action as a single class.

Interest and Maturity

Subject to the Issuer’s right to defer interest payments as described below, the Issuer will pay interest on the Notes semi-annually in arrears on and of each year during which the Notes are outstanding (each such semi-annual date, an “Interest Payment Date”), commencing on , 2022.

The Notes will bear interest from, and including, the Issue Date to, but excluding, , 2027 at a rate of % per annum. On 2027 and on every fifth anniversary of such date thereafter (each such date an “Interest Reset Date”), the interest rate on the Notes shall be reset, and the Notes will bear interest at a rate per annum equal to the Five-Year U.S. Treasury Rate on the business day immediately preceding such Interest Reset Date (each, an “Interest Rate Calculation Date”) plus, (i) for the period from, and including, , 2027 to, but excluding, , 2032, %, (ii) for the period from, and including, , 2032 to, but excluding, , 2052, % and (iii) for the period from, and including, , 2052 to, but excluding, the Maturity Date, %, in each case, to be reset on each Interest Reset Date. If interest payments are deferred or otherwise not paid, they will accrue and compound until paid at the same rate at which the Notes bear interest to the extent permitted by law.

The Notes will mature on , 2082 (the “Maturity Date”).

“Five-Year U.S. Treasury Rate” means, on any Interest Rate Calculation Date, the average of the yields on actively traded United States Treasury securities adjusted to constant maturity, for five-year maturities, for the most recent five business days appearing under the caption “Treasury Constant Maturities” in the most recent H.15 (as defined herein).

S-27

TABLE OF CONTENTS

“H.15” means the daily statistical release designated as such, or any successor publication as determined by the Calculation Agent in its sole discretion, published by the U.S. Federal Reserve Board, and “most recent H.15” means the H.15 published closest in time but prior to the close of business on the applicable Interest Rate Calculation Date.

The amount of interest payable for any interest accrual period will be computed on the basis of a 360-day year consisting of twelve 30-day months. The amount of interest payable for any period shorter than a full semi-annual period for which interest is computed will be computed on the basis of the number of days in the period using 30-day calendar months. For the purposes of disclosure under the Interest Act (Canada), and without affecting the interest payable on the Notes, whenever the interest rate on the Notes is to be calculated on the basis of a period of less than a calendar year, the yearly interest rate equivalent for such interest rate will be the interest rate multiplied by the actual number of days in the relevant calendar year and divided by 360.

In this Prospectus Supplement the term “interest” includes semi-annual interest payments and applicable interest on interest payments accrued but not paid on the applicable Interest Payment Date.

Interest payments will be made to the persons or entities in whose names the Notes are registered at the close of business on and (in each case, whether or not a business day), as the case may be, immediately preceding the relevant Interest Payment Date.

If an Interest Payment Date, a redemption date or the Maturity Date of the Notes falls on a day that is not a business day, the payment of interest and principal will be made on the next succeeding business day, and, if such payment is so made, no interest on such payment will accrue for the period from and after the Interest Payment Date, the redemption date or the Maturity Date, as applicable.

Unless all of the outstanding Notes have been redeemed as of , 2027, the Issuer will appoint a calculation agent (the “Calculation Agent”) with respect to the Notes prior to the Interest Rate Calculation Date preceding , 2027. The Issuer or any of its affiliates may assume the duties of the Calculation Agent. The applicable interest rate for each Interest Reset Date will be determined by the Calculation Agent as of the applicable Interest Rate Calculation Date. If the Issuer or one of its affiliates is not the Calculation Agent, the Calculation Agent will notify the Issuer of the interest rate for the relevant Interest Reset Date promptly upon such determination. The Issuer will notify the Trustee of such interest rate, promptly upon making or being notified of such determination. The Calculation Agent’s determination of any interest rate and its calculation of the amount of interest for any Interest Reset Date beginning on or after , 2027 will be conclusive and binding absent manifest error, will be made in the Calculation Agent’s sole discretion and, notwithstanding anything to the contrary in the documentation relating to the Notes, will become effective without consent from any other person or entity. Such determination of any interest rate and calculation of the amount of interest will be on file at the Issuer’s principal offices and will be made available to any holder of the Notes upon request. In no event shall either Trustee be the Calculation Agent, nor shall either Trustee have any liability for any determination made by or on behalf of such Calculation Agent.

If the Five-Year U.S. Treasury Rate cannot be determined pursuant to the method described above, the Calculation Agent, after consulting such sources as it deems comparable to any of the foregoing calculations, or any such source as it deems reasonable from which to estimate the Five-Year U.S. Treasury Rate, will determine the Five-Year U.S. Treasury Rate in its sole discretion, provided that if the Calculation Agent determines there is an industry-accepted successor Five-Year U.S. Treasury Rate, then the Calculation Agent will use such successor rate. If the Calculation Agent has determined a substitute or successor base rate in accordance with the foregoing, the Calculation Agent in its sole discretion may determine the business day convention, the definition of “business day” and the Interest Rate Calculation Date to be used and any other relevant methodology for calculating such substitute or successor base rate, including any adjustment factor needed to make such substitute or successor base rate comparable to the Five-Year U.S. Treasury Rate, in a manner that is consistent with industry-accepted practices for such substitute or successor base rate.

Specified Denominations

The Notes will be issued only in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Deferral Right

So long as no event of default has occurred and is continuing, the Issuer may elect, at its sole option, at any date other than an Interest Payment Date, to defer the interest payable on the Notes on one or more occasions for up to

S-28

TABLE OF CONTENTS

five consecutive years (a “Deferral Period”). There is no limit on the number of Deferral Periods that may occur. Such deferral will not constitute an event of default or any other breach under the Indenture and the Notes. Deferred interest will accrue, compounding on each subsequent Interest Payment Date, until paid. A Deferral Period terminates on any Interest Payment Date on which the Issuer pays all accrued and unpaid interest on such date. No Deferral Period may extend beyond the Maturity Date and for greater certainty, all accrued and unpaid interest shall be due and payable at maturity.

The Issuer will give the holders of the Notes written notice of its election to commence or continue a Deferral Period at least 10 days and not more than 60 days before the next Interest Payment Date.

Dividend Stopper Undertaking

Unless the Issuer has paid all accrued and unpaid interest on the Notes, the Issuer will not:

(i)	declare any dividend on the Dividend Restricted Shares or pay any interest on any Parity Notes (other than stock dividends on Dividend Restricted Shares);

(ii)

redeem, purchase or otherwise retire any Dividend Restricted Shares or Parity Notes (except (a) with respect to Dividend Restricted Shares, out of the net cash proceeds of a substantially concurrent issue of Dividend Restricted Shares or (b) pursuant to any purchase obligation, sinking fund, retraction privilege or mandatory redemption provisions attaching to any series of Dividend Restricted Shares); or

(iii)

make any payment to holders of any of the Dividend Restricted Shares or any Parity Notes in respect of dividends not declared or paid on such Dividend Restricted Shares or interest not paid on such Parity Notes, respectively (the “Dividend Stopper Undertaking”).

“Dividend Restricted Shares” means, collectively, the Issuer Preferred Shares and the Issuer Common Shares.

“Parity Notes” means any class or series of the Issuer’s indebtedness currently outstanding or hereafter created which ranks on a parity with the Notes (prior to any Automatic Conversion (as defined below)) as to distributions upon liquidation, dissolution or winding-up. As of the issue date of the Notes, the Issuer’s 6.875% Fixed-to-Floating Subordinated Notes – Series 2018-A due October 17, 2078 and the Issuer’s 6.20% Fixed-to-Floating Subordinated Notes – Series 2019-A due July 1, 2079 constitute the only Parity Notes outstanding. Following completion of the Concurrent Canadian Offering, the Series 2022-A Notes will also constitute Parity Notes.

It is in the interest of the Issuer to ensure that it timely pays interest on the Notes so as to avoid triggering the Dividend Stopper Undertaking.

Automatic Conversion

The Notes, including accrued and unpaid interest (including deferred interest) thereon, will be converted automatically (the “Automatic Conversion”), without the consent of the holders thereof, into shares of a newly issued series of preferred shares of the Issuer (the “Conversion Preferred Shares”) upon the occurrence of: (i) the making by the Issuer of a general assignment for the benefit of its creditors or a proposal (or the filing of a notice of its intention to do so) under the Bankruptcy and Insolvency Act (Canada); (ii) any proceeding instituted by the Issuer seeking to adjudicate it as bankrupt (including any voluntary assignment in bankruptcy) or insolvent or, where the Issuer is insolvent, seeking liquidation, winding up, dissolution, reorganization, arrangement, adjustment, protection, relief or composition of its debts under any law relating to bankruptcy or insolvency in Canada, or seeking the entry of an order for the appointment of a receiver, interim receiver, trustee or other similar official for the Issuer or any substantial part of its property and assets in circumstances where the Issuer is adjudged as bankrupt (including any voluntary assignment in bankruptcy) or insolvent; (iii) a receiver, interim receiver, trustee or other similar official is appointed over the Issuer or for any substantial part of its property and assets by a court of competent jurisdiction in circumstances where the Issuer is adjudged as bankrupt (including any voluntary assignment in bankruptcy) or insolvent under any law relating to bankruptcy or insolvency in Canada; or (iv) any proceeding is instituted against the Issuer seeking to adjudicate it as bankrupt (including any voluntary assignment in bankruptcy) or insolvent, or where the Issuer is insolvent, seeking liquidation, winding up, dissolution, reorganization, arrangement, adjustment, protection, relief or composition of its debts under any law relating to bankruptcy or insolvency in Canada, or seeking the entry of an order for the appointment of a receiver, interim receiver, trustee or other similar official for the Issuer or any substantial part of its property and assets in circumstances where the Issuer is adjudged as bankrupt or insolvent under any law relating to bankruptcy or insolvency in Canada, and either such proceeding has not been

S-29

TABLE OF CONTENTS

stayed or dismissed within sixty (60) days of the institution of any such proceeding or the actions sought in such proceedings occur (including the entry of an order for relief against the Issuer or the appointment of a receiver, interim receiver, trustee, or other similar official for it or for any substantial part of its property and assets) (each, an “Automatic Conversion Event”).

The Conversion Preferred Shares will carry the right to receive cumulative preferential cash dividends, if, as and when declared by the Board of Directors, subject to the solvency test set out in the Canada Business Corporations Act or any other applicable law, at the Perpetual Preferred Share Rate, payable on each semi-annual dividend payment date, subject to any applicable withholding Tax. See “Description of the Conversion Preferred Shares.”

The Automatic Conversion shall occur upon an Automatic Conversion Event (the “Conversion Time”). As of the Conversion Time, the Notes shall be automatically converted, without the consent of the holders of the Notes, into a newly issued series of fully-paid Conversion Preferred Shares. At such time, all outstanding Notes shall be deemed to be immediately and automatically surrendered and cancelled without need for further action by noteholders, who shall thereupon automatically cease to be holders thereof and all rights of any such holder as a debtholder of the Issuer shall automatically cease. At the Conversion Time, holders of the Notes will receive one Conversion Preferred Share for each $1,000 principal amount of Notes previously held together with the number of Conversion Preferred Shares (including fractional shares, if applicable) calculated by dividing the amount of accrued and unpaid interest (including deferred interest), if any, on the Notes, by $1,000.

Upon an Automatic Conversion of the Notes, the Issuer reserves the right not to issue some or all, as applicable, of the Conversion Preferred Shares to Ineligible Persons. In such circumstances, the Issuer will hold all Conversion Preferred Shares that would otherwise be delivered to Ineligible Persons, as agent for such Ineligible Persons, and will attempt to facilitate the sale of such shares through a registered broker or dealer retained by the Issuer for the purpose of effecting the sale (to parties other than the Issuer, its affiliates or other Ineligible Persons) on behalf of such Ineligible Persons of such Conversion Preferred Shares. There can be no assurance that the Issuer will be successful in such attempts. Such sales, if any, may be made at any time and any price. The Issuer will not be subject to any liability for failing to sell Conversion Preferred Shares on behalf of any such Ineligible Persons or at any particular price on any particular day. The net proceeds received by the Issuer from the sale of any such Conversion Preferred Shares will be divided among the Ineligible Persons in proportion to the number of Conversion Preferred Shares that would otherwise have been delivered to them, after deducting the costs of sale and any applicable Taxes or withholding on account of Taxes, if any. The Issuer will make payment of the aggregate net proceeds to the Clearing Agency (if the Notes are then held in the book-entry only system) or to the registrar and transfer agent (in all other cases) for distribution to such Ineligible Persons in accordance with the applicable procedures of the Clearing Agency or otherwise.

As a precondition to the delivery of any certificate or other evidence of issuance representing any Conversion Preferred Shares or related rights following an Automatic Conversion, the Issuer may require a holder of Notes (and persons holding Notes represented by such holder of Notes) to deliver a declaration, in form and substance satisfactory to the Issuer, confirming compliance with any applicable regulatory requirements to establish that such holder of Notes is not, and does not represent, an Ineligible Person.

As the events that give rise to an Automatic Conversion are bankruptcy and related events, it is in the interest of the Issuer to ensure that an Automatic Conversion does not occur, although the events that could give rise to an Automatic Conversion may be beyond the Issuer’s control.

Optional Redemption Right

The Issuer may, at its option, on giving not more than 60 days’ nor less than 30 days’ prior notice to the holders, redeem the Notes, in whole at any time or in part from time to time, on any date during a Par Call Period (as defined below) at a redemption price equal to 100.00% of the principal amount of the Notes redeemed together with accrued and unpaid interest (including deferred interest, if any) thereon to, but excluding, the date fixed for redemption.

At any time not during a Par Call Period, the Issuer may, at its option, on giving not more than 60 days’ nor less than 30 days’ prior notice to the holders, redeem the Notes, in whole at any time or in part from time to time, at a redemption price equal to the greater of (i) 100.00% of the principal amount of the Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on such Notes (not including any portion of such payments of interest accrued as of the date fixed for redemption) that would be due if the Notes matured on the first day of the next succeeding Par Call Period, discounted to the date fixed for redemption (assuming

S-30

TABLE OF CONTENTS

a 360-day year comprising twelve 30-day months) at the Treasury Rate (as defined below) plus 50 basis points and on a semi-annual basis; plus, in each case, accrued and unpaid interest (including deferred interest, if any) thereon to, but excluding, the date fixed for redemption.

“Treasury Rate” means (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published H.15 for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the remaining term of the Notes (assuming the Notes matured on the first day of the next Par Call Period), yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month) or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated by the Issuer using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. The Treasury Rate shall be calculated by the Issuer on the third business day preceding the redemption date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the Notes to be redeemed if the Notes matured on the first day of the next Par Call Period.

“Comparable Treasury Price” means (1) the average of four Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means any one of BofA Securities, Inc. or Wells Fargo Securities, LLC and their successors, as specified by the Issuer, or, if neither of such firms is willing or able to select the Comparable Treasury Issue, an independent investment banking institution of national standing in the United States appointed by the Issuer.

A “Par Call Period” means the period from, and including, the immediately preceding an Interest Reset Date to, and including, that particular Interest Reset Date.

“Reference Treasury Dealer” means each of BofA Securities, Inc. or Wells Fargo Securities, LLC and their respective successors and two other primary U.S. government securities dealers (each a “Primary Treasury Dealer”), as specified by the Issuer; provided, that (1) if any of the foregoing shall cease to be a Primary Treasury Dealer, the Issuer will substitute therefor another Primary Treasury Dealer and (2) if the Issuer fails to select a substitute within a reasonable period of time, then the substitute will be a Primary Treasury Dealer selected by the Independent Investment Banker after consultation with the Issuer.

“Reference Treasury Dealer Quotations” means, with respect to a Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed, in each case, as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date.

Subject to the satisfaction or waiver of any conditions specified in the relevant notice of redemption, as further described below, notice of redemption shall be irrevocable and on the redemption date, the Notes subject to redemption shall become due and payable at the redemption price, and from and after such date (unless the Issuer shall default in the payment of the redemption price and accrued interest) such Notes shall cease to bear interest. Notes that are redeemed shall be cancelled and shall not be reissued. For the avoidance of doubt, whenever any determination is required to be made as to whether any redemption occurs within or not within a Par Call Period or any other specified period, the actual date of redemption and not the date of notice of redemption shall govern.

Notice of any redemption of Notes may, at the Issuer’s discretion, be given subject to one or more conditions precedent, including, but not limited to, completion of a corporate transaction that is pending (such as an equity or equity-linked offering, an incurrence of indebtedness or an acquisition or other strategic transaction involving a change of control of the Issuer or another entity). If such redemption is so subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or otherwise waived on or prior to the business day immediately preceding the relevant redemption date.

S-31

TABLE OF CONTENTS

In the event that the Issuer redeems or purchases any of the Notes, the Issuer intends (without thereby assuming a legal obligation) to do so only to the extent the aggregate redemption or purchase price is equal to or less than the net proceeds, if any, received by the Issuer from new issuances during the period commencing on the 360th calendar day prior to the date of such redemption or purchase of securities which are assigned by S&P (as defined herein) at the time of sale or issuance, an aggregate equity credit that is equal to or greater than the equity credit assigned to the Notes to be redeemed or purchased (but taking into account any changes in hybrid capital methodology or another relevant methodology or the interpretation thereof since the issuance of the Notes), unless the Notes are redeemed pursuant to a Rating Event (to the extent it is triggered by a change of methodology at S&P), or a Tax Event.

Redemption on Tax Event or Rating Event

After the occurrence of a Tax Event, the Issuer may, at its option, on giving not more than 60 days’ nor less than 30 days’ prior notice to the holders of the Notes, redeem all (but not less than all) of the Notes. The redemption price per $1,000 principal amount of Notes will be equal to 100.00% of the principal amount thereof, together with accrued and unpaid interest (including deferred interest, if any) thereon to, but excluding, the date fixed for redemption.

A “Tax Event” means the Issuer has received an opinion of counsel of nationally recognized standing in the United States or Canada or, if applicable, the Relevant Taxing Jurisdiction experienced in such matters to the effect that, as a result of (i) any amendment or change to the laws (or any regulations or rulings thereunder) of any Relevant Taxing Jurisdiction or any applicable tax treaty or (ii) any change in the application, administration or interpretation of such laws, regulations, rulings or treaties (including any judicial decision rendered by a court of competent jurisdiction with respect to such laws, regulations, rulings or treaties), in each of (i) and (ii), by any legislative body, court, governmental authority or agency, regulatory body or taxing authority, which amendment or change is effective on or after the Issue Date (or if the Relevant Taxing Jurisdiction has changed since the Issue Date, the date on which the applicable jurisdiction became a Relevant Taxing Jurisdiction) (including, for the avoidance of doubt, any such amendment or change made on or after the Issue Date (or the date on which the applicable jurisdiction became a Relevant Taxing Jurisdiction, as applicable) that has retroactive effect to a date prior to the Issue Date (or the date on which the applicable jurisdiction became a Relevant Taxing Jurisdiction, as applicable)), (A) the Issuer has been or will be obligated to pay Additional Amounts as described under the caption “—Payment of Additional Amounts,” and the Issuer cannot avoid such obligation by taking commercially reasonable measures to avoid it; or (B) there is more than an insubstantial risk that interest payable by the Issuer on the Notes is not deductible, or within 90 days would not be deductible, in whole or in part, by the Issuer for Canadian federal income tax purposes.

At any time within 120 days following the occurrence of a Rating Event, the Issuer may, at its option, on giving not more than 60 days’ nor less than 30 days’ prior notice to the holders of the Notes, redeem all (but not less than all) of the Notes. The redemption price per $1,000 principal amount of Notes will be equal to 102.00% of the principal amount thereof, together with accrued and unpaid interest (including deferred interest, if any) thereon to, but excluding, the date fixed for redemption.

A “Rating Event” means a change to the methodology or criteria that were employed by any nationally recognized statistical rating organization for purposes of assigning equity credit to securities such as the Notes on the Issue Date, which either (i) shortens the period of time during which equity credit pertaining to the Notes would have been in effect had the methodology not been changed, or (ii) reduces the amount of equity credit assigned to the Notes as compared with the amount of equity credit that such rating agency had assigned to the Notes as of the Issue Date.

For greater clarity, notwithstanding the occurrence of a Tax Event or Rating Event, the Issuer shall continue to have the option to redeem the Notes in accordance with its optional redemption right described above.

Purchase for Cancellation

Subject to the Dividend Stopper Undertaking, the Notes may be purchased, in whole or in part, by the Issuer in the open market or by tender or private contract. Notes purchased by the Issuer shall be cancelled and shall not be reissued. The purchase price payable by the Issuer will be paid in cash.

Subordination

The Notes will be direct unsecured subordinated obligations of the Issuer. The payment of principal and interest on the Notes, to the extent provided in the Indenture, will be subordinated in right of payment to the prior payment in full of all present and future Senior Indebtedness, and will be effectively subordinated to all indebtedness and obligations of the Issuer’s subsidiaries.

S-32

TABLE OF CONTENTS

In the event (i) of any insolvency or bankruptcy proceedings or any receivership, liquidation, reorganization or other similar proceedings in respect of the Issuer or a substantial part of its property, or of any proceedings for liquidation, dissolution or other winding-up of the Issuer, or (ii) subject to the subordination provisions in the Indenture that a default shall have occurred with respect to payments due on any Senior Indebtedness, or there shall have occurred an event of default (other than a default in payment) in respect of any Senior Indebtedness permitting the holder or holders thereof to accelerate the maturity thereof, or (iii) that the principal of and accrued interest on the Notes shall have been declared due and payable pursuant to the Indenture and such declaration shall not have been rescinded and annulled as provided therein, then the holders of Senior Indebtedness shall first be entitled to receive payment of the full amount due thereon before the holders of the Notes are entitled to receive a payment on account of the principal or interest on the Notes, including, without limitation, any payments made pursuant to any redemption or purchase for cancellation.

“Senior Indebtedness” means obligations (other than non-recourse obligations, debt securities (including the Notes) issued under the Indenture or any other obligations specifically designated as being subordinate in right of payment to Senior Indebtedness) of, or guaranteed or assumed by, the Issuer for borrowed money or evidenced by bonds, debentures or notes or obligations of the Issuer for or in respect of bankers’ acceptances (including the face amount thereof), letters of credit and letters of guarantee (including all reimbursement obligations in respect of each of the foregoing) or other similar instruments, and amendments, renewals, extensions, modifications and refunding of any such indebtedness or obligation. As of September 30, 2021, the Issuer’s Senior Indebtedness (excluding undrawn letters of credit) totaled approximately $1.17 billion.

In addition, as of September 30, 2021, the total long-term indebtedness of the Issuer’s subsidiaries was approximately $5.08 billion (including securities due within one year).

Events of Default

An event of default in respect of the Notes will occur only if the Issuer defaults (i) on the payment of principal or premium or Additional Amounts, if any, when due and payable, (ii) on the payment of interest (including Additional Amounts) when due and payable and such default continues for 30 days (provided, however, that if the Issuer, at its sole option, elects to defer interest payments as described under “—Deferral Right”, the date on which such payment is due and payable shall be the date on which the Issuer is required to make payment following such deferral), (iii) in the performance of the covenant described under the caption “Merger, Amalgamation, Consolidation, Sale, Lease or Conveyance” or (iv) in the performance of, or breaches, any covenant of the Issuer under the Indenture (other than a covenant or a default in whose performance or breach is specifically dealt with in clause (i), (ii) or (iii) above), and such default or breach continues for a period of 90 days after there has been given written notice by registered or certified mail, to the Issuer by either Trustee (with a copy to the other Trustee), or to the Issuer and the Trustees by the holders of at least 25% in principal amount of the Notes, specifying such default or breach and requiring it to be remedied.

If an event of default has occurred and is continuing, and the Notes have not already been automatically converted into Conversion Preferred Shares, then the Issuer shall without notice from a Trustee be deemed to be in default under the Indenture and the Notes and the U.S. Trustee may, in its discretion and shall upon the request of holders of not less than 25% of the principal amount of Notes then outstanding under the Indenture, demand payment of the principal or premium or Additional Amounts, if any, together with any accrued and unpaid interest (including Additional Amounts) up to (but excluding) such date, which shall immediately become due and payable in cash, and may institute legal proceedings for the collection of such aggregate amount where the Issuer fails to make payment thereof upon such demand.

The holders of not less than a majority in principal amount of the Notes then outstanding may, on behalf of the holders of all Notes then outstanding, waive a past default under the Indenture and its consequences, except (i) in the payment of the principal of, or any premium, Additional Amounts or interest (including Additional Amounts) on, any Note or (ii) in respect of a covenant or provision of the Indenture which cannot be modified or amended without the consent of each holder of the Notes as described under the caption “—Amendment, Supplement and Waiver.”

Additional Covenants

In addition to the Dividend Stopper Undertaking, the Issuer will covenant for the benefit of the holders of the Notes that it will not create or issue any Issuer Preferred Shares which, in the event of insolvency, liquidation, dissolution or winding-up of the Issuer, would rank in right of payment in priority to the Conversion Preferred Shares.

S-33

TABLE OF CONTENTS

Issue of Conversion Preferred Shares in Connection with Automatic Conversion

All corporate action necessary to authorize the Issuer to issue Conversion Preferred Shares pursuant to the terms of the Notes will be completed prior to the closing of the offering of the Notes.

Merger, Amalgamation, Consolidation, Sale, Lease or Conveyance

The Indenture will provide that the Issuer will not merge, amalgamate or consolidate with any other person and will not sell, lease or convey all or substantially all of its assets to any person, unless the Issuer shall be the continuing person, or unless the successor corporation or person that acquires all or substantially all the assets of the Issuer shall expressly assume all of the covenants to be performed and conditions to be observed by the Issuer under the Indenture, and unless immediately after such merger, amalgamation, consolidation, sale, lease or conveyance, the Issuer, such person or such successor corporation shall not be in default in the performance of the covenants and conditions of such Indenture to be performed or observed by the Issuer.

If such successor corporation or person that acquires all or substantially all the assets of the Issuer is organized under the laws of a jurisdiction other than the laws of Canada or any province or territory thereof and the United States or any state thereof or the District of Columbia, such successor corporation or person shall assume the Issuer’s obligations under the Indenture to pay Additional Amounts, with the name of such successor jurisdiction being included in addition to Canada in each place that Canada appears in “—Payment of Additional Amounts,” including the definition of “Relevant Taxing Jurisdiction.”

Payment of Additional Amounts

All payments made by or on account of any obligation of the Issuer under or with respect to the Notes shall be made free and clear of and without withholding or deduction for, or on account of, any present or future Taxes, unless the Issuer is required to withhold or deduct Taxes by law or by the interpretation or administration thereof by the relevant government authority or agency. If the Issuer is so required to withhold or deduct any Taxes imposed by the Government of Canada or any province or territory thereof or by any authority or agency therein or thereof having power to tax (a “Relevant Taxing Jurisdiction,” and such Taxes, “Canadian Taxes”) from any payment made under or with respect to the Notes, the Issuer shall pay as additional interest such additional amounts (hereinafter “Additional Amounts”) as may be necessary so that the net amount received by each holder of the Notes (including Additional Amounts) after such withholding or deduction for Canadian Taxes shall not be less than the amount the holder of the Notes would have received if such Canadian Taxes had not been withheld or deducted; provided, however, that no Additional Amounts shall be payable with respect to a payment made to a holder of the Notes in respect of a holder or beneficial owner (i) with which the Issuer does not deal at arm’s length (for purposes of the Tax Act) at the time of the making of such payment; (ii) which is subject to such Canadian Taxes by reason of the failure to comply with any certification, identification, information, documentation or other reporting requirement by a holder or beneficial owner of the Notes if compliance is required by law, regulation, administrative practice or an applicable treaty as a precondition to exemption from, or a reduction in, the rate of deduction or withholding of, such Canadian Taxes; (iii) where all or any portion of the amount paid to such holder of the Notes relates to an amount that is or was deemed to be a dividend paid to such holder pursuant to subsection 214(16) of the Tax Act; (iv) which is subject to such Canadian Taxes by reason of its carrying on business in or being connected with Canada or any province or territory thereof (including, without limitation, by being or having been a national, domiciliary or resident, or treated as a resident, of, or physically present in or having or having had a permanent establishment in, Canada or any province or territory thereof) otherwise than by the mere holding of Notes or the receipt of payments thereunder; (v) in respect of any applicable Taxes that are payable other than by withholding from payments under or with respect to the Notes; (vi) in respect of any estate, inheritance, gift, sale, transfer, personal property, excise or similar applicable Taxes; (vii) if the applicable Taxes would not have been imposed but for the presentation of such Note (in cases in which presentation is required) more than 30 days after the later of the date on which the relevant payment became due and payable pursuant to the terms thereof or was made or duly provided for; (viii) in respect of any applicable Taxes to the extent such applicable Taxes result from the presentation of any Note for payment (where presentation is required for payment) and the payment can be made without such withholding or deduction by the presentation of the Note for payment by at least one other paying agent; (ix) for any Taxes imposed pursuant to Sections 1471 through 1474 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”) (or any amended or successor version of such sections) (“FATCA”), any regulations or other official guidance thereunder, any agreement entered into pursuant to section 1471(b)(1) of the Code, any intergovernmental agreement entered into between a non-U.S. jurisdiction and the United States in connection with FATCA or any law, regulation or other

TABLE OF CONTENTS

official guidance enacted in any jurisdiction implementing FATCA; and (x) in respect of any combination of applicable Taxes referred to in the preceding clauses (i) through (ix). The Issuer shall make such withholding or deduction and remit the full amount deducted or withheld to the relevant authority as and when required under applicable law.

Furthermore, Additional Amounts shall not be paid for any applicable Taxes if the holder is a fiduciary, partnership, limited liability company or person other than the sole beneficial owner of that payment to the extent that such payment would be required to be included in the income under the laws of the Relevant Taxing Jurisdiction, for tax purposes, of a beneficiary or settlor with respect to the fiduciary, a partner or member of that partnership or limited liability company or a beneficial owner who would not have been entitled to such Additional Amounts had that beneficiary, settlor, partner, member or beneficial owner been the holder thereof.

Whenever in this “Description of the Notes” there is mentioned, in any context, (1) the payment of principal or premium, (2) purchase prices in connection with a purchase of Notes, (3) interest, or (4) any other amount payable on or with respect to the Notes, such reference shall be deemed to include payment of any Additional Amounts to the extent that, in such context, such Additional Amounts are, were or would be payable in respect thereof.

The Issuer will pay any present or future stamp, court, documentary or similar Taxes that arise in any taxing jurisdiction from the execution, delivery, enforcement or registration of the Notes, the Indenture, or any other document or instrument required in relation thereof, and the Issuer agrees to indemnify the holders for any such Taxes paid by such holders. The obligations described under this heading will survive any termination, defeasance or discharge of the Indenture.

If Additional Amounts are required to be paid as a result of a Tax Event, the Issuer may elect to redeem the outstanding Notes. See “—Redemption on Tax Event or Rating Event” above.

Amendment, Supplement and Waiver

The Indenture or the Notes may be amended without the consent of any holder of outstanding Notes for any of the following purposes (a) to evidence the succession of another person to the Issuer and the assumption by such successor of the covenants of the Issuer in the Indenture and the Notes in accordance with the covenant described under “—Merger, Amalgamation, Consolidation, Sale, Lease or Conveyance,” (b) to add to the covenants of the Issuer or any other obligor for the benefit of holders of the Notes or surrender any right or power under the Indenture conferred upon the Issuer, (c) to add any additional events of default for the benefit of the holders of the Notes, (d) to secure the Notes or add guarantees with respect to the Notes, (e) to effect or maintain, or otherwise comply with the requirements of the SEC in connection with the qualification of the Indenture under the Trust Indenture Act, (f) to evidence and provide for the acceptance of appointment by a successor Trustee or to add or change any of the provisions of the Indenture as shall be necessary to provide for or facilitate the administration of the trusts by multiple Trustees or the removal of one or more of the Trustees, (g) to cure any ambiguity, to correct or supplement any provision of the Indenture which may be defective or inconsistent with any other provisions of the Indenture, or to make any other provisions with respect to matters or questions arising under the Indenture, provided that such action pursuant to this clause (g) shall not adversely affect the interests of holders of Notes in any material respect, (h) to conform the text of the Indenture or the terms of the Notes to this “Description of the Notes” or (i) to make any other change that does not adversely affect the interests of holders of Notes in any material respect.

The Indenture or the Notes may be amended with the consent of the holders of not less than a majority in principal amount of the outstanding Notes; provided that, in any case, without the consent of each holder of the outstanding Notes affected thereby, the Issuer and the Trustees may not (a) change the Stated Maturity of the principal of, or any installment of principal or interest on, the Notes, (b) reduce the principal amount thereof or reduce the rate of interest thereon, (c) reduce any premium payable on redemption thereof, (d) change any obligation of the Issuer to pay Additional Amounts, (e) change the currency in which principal, and any premium, Additional Amounts or interest thereon is payable, (f) impair the right to institute suit for the enforcement of any payment on any of the Notes when due, (g) reduce the percentage in principal amount of the Notes, the consent of whose holders is required for any amendment or waiver of compliance with certain provisions of the Indenture or certain defaults thereunder and their consequences provided for in the Indenture, (h) modify the provisions of the Indenture relating to amendments and waivers, waivers of past defaults and statements by officers as to default, except to increase any percentage of holders whose consent is required for such amendment or waiver or to provide that certain provisions of the Indenture cannot be modified or waived without the consent of each holder of the outstanding Notes affected thereby or (i) modify the subordination provisions applicable to the Notes in a manner adverse to the holders thereof.

S-35

TABLE OF CONTENTS

The Issuer may omit in any particular instance to comply with any term, provision, or condition set forth in the Indenture if before the time for such compliance the holders of not less than a majority in principal amount of the outstanding Notes either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Issuer and the duties of the Trustees in respect of any such term, provision or condition shall remain in full force and effect.

Issue of Additional Notes

The Issuer may, at any time and from time to time, issue additional Notes or other subordinated notes without the authorization of holders of the Notes. In the event that the Issuer issues additional series of subordinated notes, the rights, privileges, restrictions and conditions attached to such additional series may vary materially from the Notes. In such event, the right of the holders of the Notes to receive interest or principal may rank pari passu with the rights of the holders of other subordinated notes.

Governing Law

The Indenture and the Notes will be governed by and construed in accordance with the laws of the of the State of New York, without regard to conflicts of laws principles thereof; provided, however, that the exercise, performance or discharge by the Canadian Co-Trustee of any of its rights, powers, duties or responsibilities hereunder shall be construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein.

Book-Entry Only Form

Upon issuance, the Notes will be represented by one or more fully registered global securities (the “Global Securities”) registered in the name of Cede & Co. (the nominee of The Depository Trust Company (the “Clearing Agency”)), or such other name as may be requested by an authorized representative of the Clearing Agency. The authorized denominations of each Note will be $2,000 and integral multiples of $1,000 in excess thereof. Accordingly, the Notes may be transferred or converted only through the Clearing Agency and its participants. Except as described below, owners of beneficial interests in the Global Securities will not be entitled to receive the Notes in definitive form.

Beneficial interests in the Notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in the Clearing Agency. Holders of the Notes may elect to hold interests in the Notes in book-entry form through either the Clearing Agency in the U.S. or Clearstream Banking, société anonyme (“Clearstream”), or Euroclear Bank S.A./N.V. (“Euroclear”), if they are participants in those systems, or indirectly through organizations which are participants in those systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their respective depositaries, which in turn will hold such interests in customers’ securities accounts in the depositaries’ names on the books of the Clearing Agency.

Each person owning a beneficial interest in a Global Security must rely on the procedures of the Clearing Agency and, if such person is not a participant, on the procedures of the participant through which such person owns its interest in order to exercise any rights of a holder under the Indenture. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of such securities in certificated form. Such limits and such laws may impair the ability to transfer beneficial interests in a Global Security representing the Notes.

The following is based on information furnished by the Clearing Agency:

The Clearing Agency is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the U.S. Exchange Act. The Clearing Agency holds securities that its participants (“Participants”) deposit with the Clearing Agency. The Clearing Agency also facilitates the settlement among Participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in Participants’ accounts, thereby eliminating the need for physical movement of securities certificates. These direct Participants (“Direct Participants”) include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. The Clearing Agency is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding

S-36

TABLE OF CONTENTS

company for the Clearing Agency, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the Clearing Agency’s system is also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). The rules applicable to the Clearing Agency and its Participants are on file with the SEC.

Purchases of the Notes under the Clearing Agency’s system must be made by or through Direct Participants, which will receive a credit for such Notes on the Clearing Agency’s records. The ownership interest of each actual purchaser of each Note represented by a Global Security (“Beneficial Owner”) is in turn to be recorded on the Direct Participants’ and Indirect Participants’ records. Beneficial Owners will not receive written confirmation from the Clearing Agency of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct Participants or Indirect Participants through which such Beneficial Owner entered into the transaction. Transfers of ownership interests in a Global Security representing the Notes are to be accomplished by entries made on the books of Participants acting on behalf of Beneficial Owners. Beneficial Owners of a Global Security representing the Notes will not receive the Notes in definitive form representing their ownership interests therein, except in the event that use of the book-entry system for such Notes is discontinued.

To facilitate subsequent transfers, the Global Securities representing the Notes which are deposited with the Clearing Agency are registered in the name of the Clearing Agency’s nominee, Cede & Co., or such other name as may be requested by an authorized representative of the Clearing Agency. The deposit of Global Securities with the Clearing Agency and their registration in the name of Cede & Co. or such other nominee effect no change in beneficial ownership. The Clearing Agency has no knowledge of the actual Beneficial Owners of the Global Securities representing the Notes; the Clearing Agency’s records reflect only the identity of the Direct Participants to whose accounts such Notes are credited, which may or may not be the Beneficial Owners. The Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by the Clearing Agency to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Neither the Clearing Agency nor Cede & Co. (nor such other nominee of the Clearing Agency) will consent or vote with respect to the Global Securities representing the Notes. Under its usual procedures, the Clearing Agency mails an “omnibus proxy” to the Issuer as soon as possible after the applicable record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those Direct Participants to whose accounts the Notes are credited on the applicable record date (identified in a listing attached to the omnibus proxy).

Principal, premium, if any, and interest payments on the Global Securities representing the Notes will be made to Cede & Co. (or such other nominee as may be requested by an authorized representative of the Clearing Agency). The Clearing Agency’s practice is to credit Direct Participants’ accounts, upon the Clearing Agency’s receipt of funds and corresponding detailed information from the Issuer or the Trustee, on the applicable payment date in accordance with their respective holdings shown on the Clearing Agency’s records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such Participant and not of the Clearing Agency, the applicable Trustee or the Issuer, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal, premium, if any, and interest to Cede & Co. (or such other nominee as may be requested by an authorized representative of the Clearing Agency) is the responsibility of the Issuer or the applicable Trustee (provided it has received funds from the Issuer), disbursement of such payments to Direct Participants shall be the responsibility of the Clearing Agency, and disbursement of such payments to the Beneficial Owners shall be the responsibility of Direct and Indirect Participants.

The Clearing Agency may discontinue providing its services as securities depository with respect to the Notes at any time by giving reasonable notice to the Issuer or the U.S. Trustee. Under such circumstances, in the event that a successor securities depository is not obtained, Notes in definitive form are required to be printed and delivered to each holder.

The Issuer may decide to discontinue use of the system of book-entry transfers through the Clearing Agency (or a successor securities depositary). In that event, the Notes in definitive form will be printed and delivered.

TABLE OF CONTENTS

Clearstream advises that it is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations (“Clearstream participants”), and facilitates the clearance and settlement of securities transactions between Clearstream participants through electronic book-entry changes in accounts of Clearstream participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to Clearstream participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier). Clearstream participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations and may include the Underwriters of this Offering. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream participant, either directly or indirectly.

Distributions with respect to interests in the Notes held beneficially through Clearstream will be credited to cash accounts of Clearstream participants in accordance with its rules and procedures, to the extent received by the Clearing Agency for Clearstream.

Euroclear advises that it was created in 1968 to hold securities for participants of Euroclear (“Euroclear participants”), and to clear and settle transactions between Euroclear participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear includes various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A./N.V. (“Euroclear Operator”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator. Euroclear participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the Underwriters of the Offering of the Notes. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly.

Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law (collectively, the “Terms and Conditions”). The Terms and Conditions govern transfers of securities and cash within the Euroclear System, withdrawals of securities and cash from the Euroclear System, and receipts of payment with respect to securities in the Euroclear System. All securities in the Euroclear System are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear participants, and has no records of or relationship with persons holding through Euroclear participants.

Distributions with respect to the Notes held beneficially through the Euroclear System will be credited to the cash accounts of Euroclear participants in accordance with the Terms and Conditions, to the extent received by the U.S. depositary for the Euroclear System.

The information in this section concerning the Clearing Agency and the Clearing Agency’s book-entry system, Clearstream and Euroclear has been obtained from sources that the Issuer believes to be reliable, but is subject to any changes to the arrangements between the Issuer and the Clearing Agency and any changes to such procedures that may be instituted unilaterally by the Clearing Agency, Clearstream and Euroclear.

Transfers

Transfers of ownership of the Notes will be effected only through records maintained by the Clearing Agency for such Notes with respect to interests of Participants and on the records of Participants with respect to interests of persons other than Participants. Holders of the Notes who are not Participants, but who desire to purchase, sell or otherwise transfer ownership of or other interests in the Notes, may do so only through Participants. The ability of a holder to pledge Notes or otherwise take action with respect to such holder’s interest in Notes (other than through a Participant) may be limited due to the lack of a physical certificate. See “Risk Factors—Risks Relating to the Notes—Market for Notes.”

As long as the Notes are held in the Clearing Agency’s book-entry only system, the responsibility and liability of the Trustees and/or the Issuer in respect of the Notes is limited to making payment of any amount due on the Notes and/or making delivery of Conversion Preferred Shares in respect thereof to the Clearing Agency.

Subject to the terms and conditions set forth in an Underwriting Agreement among the Corporation and the Underwriters, the Corporation has agreed to sell to the Underwriters, and each of the Underwriters has agreed, severally and not jointly, to purchase from the Corporation, the principal amount of Notes set forth opposite its name below.

Subject to the terms and conditions set forth in the Underwriting Agreement, the Underwriters have agreed, severally and not jointly, to purchase all of the Notes sold under the Underwriting Agreement if any of these Notes are purchased. If one or more of the Underwriters shall fail or refuse to purchase its applicable aggregate principal amount of the Notes, and the aggregate principal amount of Notes not purchased is less than or equal to 10% of the aggregate principal amount of Notes agreed to be purchased by the Underwriters pursuant to the Underwriting Agreement, each of the other Underwriters shall be obligated to purchase severally the aggregate principal amount of Notes not taken up, on a pro rata basis or as they may otherwise agree. If any one or more of the Underwriters shall fail or refuse to purchase such Notes and the aggregate principal amount of such Notes with respect to which such default occurs exceeds 10% of the aggregate principal amount of Notes to be purchased on such date, and arrangements satisfactory to the Representatives and the Corporation for the purchase of such Notes are not made within 48 hours after such default, then the Underwriting Agreement shall terminate.

The Corporation has agreed to indemnify the Underwriters against certain liabilities, including liabilities under the U.S. Securities Act and any Canadian securities laws, or to contribute to payments the Underwriters may be required to make in respect of those liabilities.

The Underwriters are offering the Notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the Notes, and other conditions contained in the Underwriting Agreement, such as the receipt by the Underwriters of officer’s certificates and legal opinions. The Underwriting Agreement provides that the obligations of the Underwriters to purchase the Notes may be terminated at their discretion if there is a material adverse change in the financial markets which makes it impracticable to proceed with the offering of the Notes and may also be terminated upon the occurrence of certain stated events. The Underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part. The offering price and the other terms of the Notes have been determined by negotiation between the Corporation and the Underwriters.

This Prospectus Supplement qualifies the distribution of the Notes in the Province of Ontario solely for the purpose of registering the Notes in the United States pursuant to the multijurisdictional disclosure system adopted in the United States and Canada. This Prospectus Supplement does not qualify the Notes for distribution to purchasers in Canada, or to residents of Canada.

Commissions and Discounts

The Representatives have advised the Corporation that the Underwriters propose initially to offer the Notes at the public offering price set forth on the cover page of this Prospectus Supplement and may offer the Notes to dealers at that price less a concession not in excess of $ per Note. The Underwriters may allow, and those dealers

TABLE OF CONTENTS

may reallow, a discount not in excess of $ per Note to certain other dealers. After the initial offering, the public offering price, concession or any other term of the offering may be changed.

The following table shows the public offering price, underwriting commission and proceeds to the Corporation.

We estimate that total expenses of the Offering, including the underwriting commission, will be approximately $ .

New Issue of Notes

The Notes are a new issue of securities and the Corporation does not intend to apply to list the Notes on any securities exchange or quotation system and, consequently, there is no market through which the Notes may be sold and purchasers may not be able to resell the Notes purchased under this Prospectus Supplement and the Base Shelf Prospectus to which it relates. This may affect the pricing of the Notes in the secondary market, the transparency and availability of trading prices, the liquidity of the Notes, and the extent of issuer regulation. The Corporation is under no obligation to, and does not intend to, list the Conversion Preferred Shares on any stock exchange or other market. See “Risk Factors.”

No Sales of Similar Securities

The Corporation has agreed, with certain limited exceptions, that the Corporation will not, for a period beginning on the date of this Prospectus Supplement and ending on the closing date of this Offering, without first obtaining the prior written consent of the Representatives, directly or indirectly offer to sell, grant any option for the sale or otherwise dispose of any Notes, any security convertible into, exchangeable into or exercisable for the Notes or any debt securities substantially similar to the Notes (except the Notes issued hereby).

Price Stabilization, Short Positions

In connection with the Offering, the Underwriters may purchase and sell the Notes in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the Underwriters of a greater principal amount of Notes than they are required to purchase in the Offering. The Underwriters must close out any short position by purchasing Notes in the open market. A short position is more likely to be created if the Underwriters are concerned that there may be downward pressure on the price of the Notes in the open market after pricing that could adversely affect investors who purchase in the Offering. Stabilizing transactions consist of various bids for or purchases of Notes made by the Underwriters in the open market to peg, fix or maintain the price of the Notes prior to the completion of the Offering.

Similar to other purchase transactions, the Underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of the Notes or preventing or retarding a decline in the market price of the Notes. As a result, the price of the Notes may be higher than the price that might otherwise exist in the open market.

Neither the Corporation nor any of the Underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Notes. In addition, neither the Corporation nor any of the Underwriters make any representation that the Underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Other Relationships

Some of the Underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with the Corporation or its affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions. In particular,

S-43

TABLE OF CONTENTS

affiliates of certain of the Underwriters are lenders under the Corporation and its subsidiaries’ credit facilities, and have provided the Acquisition Financing Commitment (as defined herein), for which they have received, and in the future would receive, customary fees.

In addition, in the ordinary course of their business activities, the Underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. Certain of the Underwriters or their affiliates have a lending relationship with the Corporation and routinely hedge, and certain other of those Underwriters or their affiliates may hedge, their credit exposure to the Corporation consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Notes. Any such credit default swaps or short positions could adversely affect future trading prices of the Notes. The Underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

See “Relationship Between the Corporation and Certain Underwriters.”

Settlement

The Corporation expects that delivery of the Notes will be made against payment therefor on or about the date specified on the cover page of this Prospectus Supplement, which will be the third business day following the date of pricing of the Notes (this settlement cycle being referred to as “T+3”). Under Rule 15c6-1 of the U.S. Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes on the date of this Prospectus Supplement will be required, by virtue of the fact that the Notes initially will settle in T+3, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to make such trades should consult their own advisor.

Selling Restrictions

The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (the “EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); (ii) a customer within the meaning of Directive (EU) 2016/97, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a “qualified investor” as defined in Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”).

Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

RELATIONSHIP BETWEEN THE CORPORATION AND CERTAIN UNDERWRITERS

The Corporation expects that the net proceeds of the Offering and the net proceeds from the Concurrent Canadian Offering will be used to partially finance the Kentucky Power Acquisition, provided that, in the short-term, prior to the closing of the Kentucky Power Acquisition, the Corporation expects to use such net proceeds to reduce amounts outstanding under existing credit facilities of the Corporation and its subsidiaries, which indebtedness was principally incurred in the ordinary course of operations and to fund the Corporation’s previously disclosed growth opportunities. See “Use of Proceeds.”

BofA Securities, Inc., Wells Fargo Securities, LLC, Morgan Stanley & Co. LLC, Scotia Capital (USA) Inc., CIBC World Markets Corp., J.P. Morgan Securities LLC, RBC Capital Markets, LLC, TD Securities (USA) LLC, BMO Capital Markets Corp. and National Bank of Canada Financial Inc. are affiliates of financial institutions which are lenders (the “Lenders”) to the Corporation, Algonquin Power Co. (“APCo”) (a trust of which the Corporation is the sole unitholder), Liberty Utilities and/or Bermuda Electric Light Company Limited (“BELCO”) (a subsidiary of the Corporation) under their respective credit facilities.

Additionally, in connection with the Kentucky Power Acquisition, the Corporation obtained a syndicated acquisition financing commitment from affiliates of certain of the Underwriters (the “Acquisition Financing Commitment”), which funds shall, if drawn, be used for the purposes of financing a portion of the cash purchase price of the Kentucky Power Acquisition, certain costs associated with the assumption of certain indebtedness of the Acquired Entities and/or to provide an alternative source of funds for existing intercompany debt of the Acquired Entities. Furthermore, the Corporation engaged CIBC World Markets Inc., an affiliate of CIBC World Markets Corp., and Morgan Stanley & Co. LLC as financial advisors for the Kentucky Power Acquisition.

Accordingly, the Corporation may be considered to be a connected issuer of each of these Underwriters under applicable securities laws. In addition, the Underwriters and/or their affiliates are acting as underwriters for the Concurrent Canadian Offering and will receive fees for acting as underwriters for the Concurrent Canadian Offering.

As of December 31, 2021 there was approximately: (i) $289.9 million drawn and $1.7 million and C$2.6 million in outstanding letters of credit under the Corporation’s revolving credit facility; (ii) $14.7 million drawn and $64.4 million in outstanding letters of credit under APCo’s revolving credit facility; (iii) no amounts drawn and $73.0 million in outstanding letters of credit under Liberty Utilities’ revolving credit facility; (iv) $338.7 million in commercial paper issued by Liberty Utilities; (v) $124.6 million and C$40.9 million outstanding letters of credit under APCo’s letter of credit facility; and (vi) $64.3 million drawn under BELCO’s revolving credit facility. Additionally, on January 3, 2022, $610.4 million was drawn on the Liberty Utilities 2021 Credit Facility in connection with the closing of New York American Water acquisition. The Corporation, APCo, Liberty Utilities and BELCO are in compliance with all material terms of the agreements governing the respective facilities and the Lenders have not waived any material breach of the agreements governing such credit facilities since their execution.

The decision to distribute the Notes offered hereby and the decision to distribute the Series 2022-A Notes and the determination of the terms of the distribution of the Notes and the terms of the distribution of the Series 2022-A Notes were made through negotiations primarily between the Corporation and the Representatives, on their own behalf and on behalf of the other Underwriters. None of the Lenders were involved in the decision to offer the Notes or the decision to offer the Series 2022-A Notes and none will be involved in the determination of the terms of the distribution of the Notes or the terms of the distribution of the Series 2022-A Notes. Each of the Underwriters will receive its proportionate share of the aggregate underwriting commission payable by the Corporation to the Underwriters and the Underwriters and/or their affiliates will receive their proportionate share of the aggregate underwriting commission payable by the Corporation pursuant to the Concurrent Canadian Offering.

TABLE OF CONTENTS

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

In the opinion of Blake, Cassels & Graydon LLP, counsel to the Corporation, and Bennett Jones LLP, counsel to the Underwriters, the following is a summary of the principal Canadian federal income tax considerations generally applicable to a holder of Notes or Conversion Preferred Shares who acquires Notes pursuant to the Offering and any Conversion Preferred Shares on the conversion of such Notes and who, for purposes of the Income Tax Act (Canada) and the Regulations thereunder (the “Tax Act”) and at all relevant times, (i) is not, and is not deemed to be, resident in Canada; (ii) deals at arm’s length with the Corporation, its affiliates and the Underwriters and is not affiliated with the Corporation or any of its affiliates; (iii) deals at arm’s length with any transferee resident (or deemed to be resident) in Canada to whom the holder disposes of a Note; (iv) holds Notes and will hold any Conversion Preferred Shares as capital property; (v) does not, and is not deemed to, use or hold the Notes or Conversion Preferred Shares in a business carried on in Canada; and (vi) is not a “specified non-resident shareholder” of the Corporation for purposes of the Tax Act or a non-resident person not dealing at arm’s length with a “specified shareholder” (within the meaning of subsection 18(5) of the Tax Act) of the Corporation (a “Non-Resident Holder”). Special rules, which are not discussed in this summary, may apply to certain Non-Resident Holders that are insurers carrying on an insurance business in Canada and elsewhere or “authorized foreign banks” (as defined in the Tax Act). This summary assumes that no interest paid on the Notes will be in respect of a debt or other obligation to pay an amount to a person with whom the Corporation does not deal at arm’s length within the meaning of the Tax Act.

This summary is based upon the current provisions of the Tax Act in force as of the date hereof, all specific proposals to amend the Tax Act publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the “Tax Proposals”) and counsel’s understanding of the administrative policies and assessing practices of the Canada Revenue Agency (“CRA”) published in writing prior to the date hereof. This summary is not exhaustive of all Canadian federal income tax considerations and, except for the Tax Proposals, does not take into account or anticipate any changes in law or CRA administrative policies or assessing practices, whether by way of legislative, governmental or judicial decision or action, nor does it take into account or consider any other federal tax considerations or any provincial, territorial or foreign tax considerations, which may differ materially from those discussed herein. While this summary assumes that the Tax Proposals will be enacted in the form proposed, no assurance can be given that such proposals will be enacted in their current form, or at all.

Generally, for purposes of the Tax Act, all amounts relating to the acquisition, holding or disposition of Notes or Conversion Preferred Shares must be determined in Canadian dollars. Any such amount that is expressed or denominated in a currency other than Canadian dollars must be converted into Canadian dollars using the relevant exchange rate determined in accordance with the Tax Act.

This summary is of a general nature only and is not, and is not intended to be, and should not be construed to be, legal or tax advice to any particular Non-Resident Holder and no representation with respect to the income tax consequences to any particular Non-Resident Holder is made. Prospective purchasers of Notes should consult their own tax advisors with respect to the tax consequences of acquiring, holding and disposing of Notes and Conversion Preferred Shares having regard to their own particular circumstances.

Notes

Interest on and Disposition of the Notes

Under the Tax Act, interest, principal and premium, if any, paid or credited, or deemed to be paid or credited, to a Non-Resident Holder on Notes will not be subject to Canadian non-resident withholding tax. No other taxes on income (including taxable capital gains) will be payable under the Tax Act in respect of the acquisition, holding, redemption or disposition of Notes, or the receipt of interest, premium or principal thereon by a Non-Resident Holder solely as a consequence of such acquisition, holding, redemption or disposition of Notes.

Automatic Conversion

A conversion of Notes into Conversion Preferred Shares pursuant to an Automatic Conversion will result in a disposition of such Notes for purposes of the Tax Act for proceeds equal to the fair market value of the Conversion Preferred Shares which the Non-Resident Holder acquires, not including any amount considered to be interest. A Non-Resident Holder will not generally be subject to tax under the Tax Act in respect of such disposition. The aggregate cost to a Non-Resident Holder of the Conversion Preferred Shares issued on an Automatic Conversion will be equal to the fair market value thereof at the time of the Automatic Conversion.

S-48

TABLE OF CONTENTS

Conversion Preferred Shares

Dividends

A dividend paid or credited, or deemed to be paid or credited, to a Non-Resident Holder on Conversion Preferred Shares will generally be subject to Canadian non-resident withholding tax under the Tax Act at a rate of 25 percent, subject to any reduction in the rate of such withholding under the provisions of an income tax treaty or convention. For a Non-Resident Holder who is a resident of the United States and qualifies for the benefits of the Canada-United States Tax Convention (the “Canada-US Tax Treaty”), the rate of withholding will generally be reduced pursuant to the Canada-US Tax Treaty to 15 percent.

Dispositions

A Non-Resident Holder of Conversion Preferred Shares who disposes of or is deemed to dispose of Conversion Preferred Shares (other than as discussed under “ —Redemption or Other Acquisition by the Corporation”) will not be subject to tax under the Tax Act in respect of any capital gain realized on a disposition of Conversion Preferred Shares unless the Conversion Preferred Shares constitute, or are deemed to constitute, “taxable Canadian property” (as defined in the Tax Act) to the Non-Resident Holder at the time of the disposition and the Non-Resident Holder is not entitled to relief under an applicable income tax treaty or convention. If the Conversion Preferred Shares are not listed on a designated stock exchange, such shares will be considered taxable Canadian property if, at any time during the 60-month period immediately preceding the disposition, the Conversion Preferred Shares derived (directly or indirectly) more than 50 percent of their fair market value from one or any combination of real or immovable property situated in Canada, “Canadian resource properties”, “timber resource properties” or options in respect of, or interests in or rights in respect of, any such property (whether or not such property exists), all as defined for the purposes of the Tax Act.

If the Conversion Preferred Shares are considered taxable Canadian property to the Non-Resident Holder, a disposition or deemed disposition of such Conversion Preferred Shares (other than as discussed under “ —Redemption or Other Acquisition by the Corporation”) will generally give rise to a capital gain (or a capital loss) equal to the amount by which the proceeds of disposition of such Conversion Preferred Shares, net of any reasonable costs of disposition, exceed (or are less than) the adjusted cost base of such Conversion Preferred Shares to the Non-Resident Holder. Generally, one half of any such capital gain (a “taxable capital gain”) must be included in the Non-Resident Holder’s income for that year and one half of any such capital loss (an “allowable capital loss”) must be deducted against taxable capital gains realized in that year from dispositions of taxable Canadian property. Certain excess allowable capital losses from the dispositions of taxable Canadian property may be carried back and deducted in any of the three preceding taxation years or carried forward and deducted in any subsequent taxation year against taxable capital gains realized in such years from dispositions of taxable Canadian property subject to the rules contained in the Tax Act.

An applicable income tax treaty or convention may apply to exempt a Non-Resident Holder from tax under the Tax Act in respect of a disposition of Conversion Preferred Shares notwithstanding that such shares may constitute taxable Canadian property.

Conversion Preferred Shares are not expected to be listed on a “recognized stock exchange” (as defined in the Tax Act). As such, a Non-Resident Holder which disposes of or is deemed to dispose of Conversion Preferred Shares that are taxable Canadian property will be required to satisfy the obligations imposed under section 116 of the Tax Act. Generally, a purchaser of such Conversion Preferred Shares will be entitled to withhold an amount equal to 25% of the purchase price paid for such shares if the Non-Resident Holder does not satisfy such obligations imposed under section 116 of the Tax Act by the time of disposition. An exemption from the general obligations and withholding applicable to such a Non-Resident Holder may be available in respect of such disposition if the Conversion Preferred Shares are “treaty-exempt property” as defined in the Tax Act.

Non-Resident Holders whose Conversion Preferred Shares may be taxable Canadian property should consult their own tax advisors.

Redemption or Other Acquisition by the Corporation

If the Corporation redeems for cash or otherwise acquires the Conversion Preferred Shares, other than by way of a purchase in the open market in the manner in which shares are normally purchased by a member of the public in the open market (if one develops in respect of the Conversion Preferred Shares), the Non-Resident Holder will be

S-49

TABLE OF CONTENTS

deemed to have received a dividend equal to the amount, if any, paid by the Corporation in excess of the paid-up capital of such shares for purposes of the Tax Act at such time. Such deemed dividend will be subject to the treatment described above under “Dividends”. The difference between the amount paid and the amount of the deemed dividend will be treated as proceeds of disposition for the purposes of computing the capital gain or capital loss arising on a disposition of such shares. See the section above under the heading “—Dispositions.”

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a general summary of certain U.S. federal income tax consequences to the U.S. Holders (as defined below) of purchasing, owning and disposing of the Notes and the Conversion Preferred Shares. This summary deals only with beneficial owners who purchase the Notes in this Offering at the “issue price,” which is the first price at which a substantial amount of the Notes is sold for cash (other than to bond houses, brokers, or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers), and who hold the Notes and the Conversion Preferred Shares as capital assets for U.S. federal income tax purposes. This discussion does not describe all of the tax consequences that may be relevant to you in light of your particular circumstances, including alternative minimum tax and Medicare contribution tax consequences, as well as differing tax consequences that may apply if you are, for instance:

•	a financial institution;

•	a real investment trust, a regulated investment company or an insurance company;

•	a dealer in securities or currencies;

•	a dealer or trader in securities that uses a mark-to-market method of tax accounting;

•	holding the Notes as part of a hedging transaction, “straddle”, conversion transaction, constructive sale or other integrated transaction;

•	a person whose functional currency is not the U.S. dollar;

•	a tax-exempt entity, qualified retirement plan, individual retirement account or other deferred account;

•	a persons that owns directly, indirectly or constructively ten percent or more, by vote or value, of the outstanding equity interests of the Corporation;

•	a person subject to special tax accounting rules under Section 451(b) of the Code;

•	U.S. expatriate; or

•	partnership pass-through entity for U.S. federal income tax purposes or an investor in such a pass-through entity.

If you are an entity or arrangement classified as a partnership for U.S. federal income tax purposes, the U.S. federal income tax treatment of you and your partners will generally depend on the status of the partners and your activities. If you are a partnership owning the Notes or a partner in such partnership, you should consult your tax adviser as to the particular U.S. federal income tax consequences of owning the Notes.

This discussion is based on the Internal Revenue Code of 1986, as amended, or the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, all as of the date hereof. All of the foregoing authorities are subject to differing interpretations or change (possibly with retroactive effect), and any such differing interpretations or change may result in U.S. federal income tax consequences to you that are materially different from those described herein. No rulings from the U.S. Internal Revenue Service (the “IRS”) have been or will be sought with respect to the matters described below, and consequently, the IRS may not take a similar view of the consequences described below.

This discussion does not address any aspect of state, local or non-U.S. taxation, or any taxes other than U.S. federal income taxes. You should consult your tax adviser with regard to the application of the U.S. federal tax laws to your particular situation, as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

S-50

TABLE OF CONTENTS

You are a U.S. Holder for purposes of this discussion if for U.S. federal income tax purposes you are a beneficial owner of a Note or a Conversion Preferred Share and are:

•	an individual who is a citizen or resident of the United States;

•	a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state therein or the District of Columbia;

•	an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

•

a trust (1) the administration of which is subject to the primary supervision of a court within the U.S. and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) that has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

The following discussion is for general information only and is not intended to be, nor should it be construed to be, legal or tax advice to any holder or prospective holder of Notes and no opinion or representation with respect to the U.S. federal income tax consequences to any such holder or prospective holder is made. U.S. Holders are urged to consult their tax advisers with respect to the U.S. federal, state and local tax consequences, the non-U.S. tax consequences and the non-tax consequences of the acquisition, ownership and disposition of Notes.

Tax Treatment of the Notes

The determination of whether an instrument is properly treated as indebtedness or equity for U.S. federal income tax purposes is based on all the relevant facts and circumstances. There is no statutory, judicial or administrative authority directly addressing the U.S. federal income tax treatment of an instrument with substantially identical terms as the Notes. As a result, the U.S. federal income tax treatment of the Notes is not clear. In the absence of authority directly addressing the proper treatment of instruments such as the Notes, to the extent required to do so, we intend to treat the Notes as debt for U.S. federal income tax purposes. However, we will not request any ruling from the IRS regarding the treatment of the Notes for U.S. federal income tax purposes and the IRS or a court may conclude that the Notes should be treated as equity for U.S. federal income tax purposes. Prospective investors should consult their tax advisers as to the proper characterization of the Notes for U.S. federal income tax purposes.

Consequences if the Notes are Treated as Debt Instruments for U.S. Federal Income Tax Purposes

The discussion under this section assumes that the Notes are treated as indebtedness for U.S. federal income tax purposes.

Certain Additional Payments

In certain circumstances (e.g., as described under “Description of the Notes—Redemption on Tax Event or Rating Event”) the Corporation may be obligated to pay amounts on the Notes that are in excess of stated interest or principal on the Notes. These potential payments may implicate the provisions of U.S. Treasury regulations relating to “contingent payment debt instruments.” We do not intend to treat the possibility of paying such additional amounts as causing the notes to be treated as contingent payment debt instruments. It is possible that the IRS may take a contrary position. If the IRS takes a contrary position, you may be required to accrue interest income based upon a “comparable yield” (as defined in the Treasury regulations) determined at the time of issuance of the Notes, with adjustments to such accruals when any contingent payments are made that differ from the payments based on the comparable yield. In addition, any income on the sale or other taxable disposition of the Notes would be treated as interest income rather than as capital gain. Our determination that the Notes are not contingent payment debt instruments is binding on you unless you disclose a contrary position to the IRS in the manner that is required by applicable Treasury regulations. The remainder of this discussion assumes that the Notes are not treated as contingent payment debt instruments. You should consult your tax adviser regarding the tax consequences if the Notes were treated as contingent payment debt instruments.

Payments of Interest

In general, interest paid on the Notes should be taxable to you as ordinary income when paid or accrued in accordance with your method of accounting for U.S. federal income tax purposes, except to the extent of original issue discount (“OID”), if any. If the Notes are issued with more than a de minimis amount of OID under the

S-51

TABLE OF CONTENTS

applicable Treasury regulations (as discussed in further detail below), you must include OID in your gross income for U.S. federal income tax purposes as it accrues using the constant yield method, regardless of your method of accounting and irrespective of when you receive any payment attributable to such income. The calculation of the amount of such accruals may be complex, and therefore you should consult your tax adviser regarding the tax consequences if the Notes were treated as issued (or deemed reissued, as discussed in more detail below) with OID.

The Notes may be treated as being issued with OID as a result of our ability to defer payments of interest from time to time for up to five years, unless the likelihood of such deferral is remote. Due to the terms of the Notes and the relevant facts and circumstances, we intend to take the position, and this discussion assumes, that, as of the date of this Prospectus Supplement, the likelihood of deferring payments of interest under the terms of the Notes is remote within the meaning of the Treasury regulations referred to above. Based on the foregoing, we do not intend to treat the Notes as issued with OID by reason of our deferral option. Our position is not, however, binding on the IRS. If the IRS takes a contrary position, you may be required to accrue OID by reason of our deferral option from the time of issuance, as described below, regardless of your method of accounting for U.S. federal income tax purposes.

In the event the possibility of interest deferral were determined not to be remote, or if we in fact exercise our option to defer payments of interest, the Notes would be treated as issued with OID by reason of our deferral option at the time of issuance, or at the time of deferral, as the case may be, and all stated interest, or if interest is in fact deferred, all stated interest due after such deferral would be treated as OID. Consequently, you would be required to include interest income as it accrues using a constant yield method, regardless of your method of accounting, and before you receive any payment attributable to such income.

In addition, based on the application of the Treasury regulations applicable to variable rate debt instruments and the expected pricing terms of the Notes, we also do not expect the pricing of the Notes to result in the Notes as being treated as issued with OID for U.S. federal income tax purposes. The remainder of this discussion assumes the Notes will not be treated as issued with OID.

The amount of interest will include any amounts withheld in respect of Canadian taxes and, without duplication, any additional amounts paid with respect thereto. Interest on the Notes will generally be foreign-source income for foreign tax credit purposes.

Sale or Other Taxable Disposition of the Notes

Upon the sale or other taxable disposition of a Note, you will recognize taxable gain or loss equal to the difference between the amount realized on the sale or other taxable disposition (less any amount equal to accrued but unpaid interest, which will be taxable as interest income, as described above) and your tax basis in the Note. Assuming we do not defer interest payments on the Notes and the Notes are not otherwise treated as issued with OID, your tax basis in a Note will generally equal the cost of your Note. If the Notes are treated as issued (or deemed reissued) with OID, your tax basis in a Note will generally equal the cost of your Note, increased by any OID previously included in income, and decreased by payments received on the Note after the date of such issuance (or deemed reissuance, as applicable). Any gain or loss will generally be U.S.-source income or loss for purposes of computing your foreign tax credit limitation.

Gain or loss realized on the sale or other taxable disposition of a Note will generally be capital gain or loss and will be long-term capital gain or loss if at the time of the sale or other taxable disposition the Note has been held for more than one year. Long-term capital gains recognized by non-corporate U.S. Holders are subject to reduced tax rates. The deductibility of capital losses is subject to limitations.

Automatic Conversion

The conversion of Notes for Conversion Preferred Shares pursuant to the Automatic Conversion should be treated as a tax-free recapitalization for U.S. federal income tax purposes. Thus, no income, gain or loss should be recognized on the conversion except to the extent that there is accrued but unpaid interest at the time of the conversion (which will be treated as such). Any Conversion Preferred Shares will be treated as first being received for the accrued but unpaid interest and the remainder will be treated as received upon conversion of the Notes. Your tax basis in the Conversion Preferred Shares received (other than any such shares received with respect to accrued interest) will equal the tax basis of the Notes that were converted. Your tax basis in the Conversion Preferred Shares

S-52

TABLE OF CONTENTS

received with respect to accrued interest will equal the fair market value of the shares received. Your holding period for the Conversion Preferred Shares received will include your holding period for the Notes converted, except that the holding period of any shares received with respect to accrued interest will commence on the day after the date of receipt.

Consequences if the Notes are Treated as Equity for U.S. Federal Income Tax Purposes

The discussion under this section assumes that the Notes are treated as equity for U.S. federal income tax purposes. In addition, the discussion under this section generally assumes that we are not, and will not become, a passive foreign investment company, or a “PFIC”, as described below.

Payments of Interest

Payments of interest on the Notes will be treated as dividends to the extent paid out of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent that the amount of any distribution exceeds our current and accumulated earnings and profits for a taxable year, the distribution would be treated as a tax-free return of capital to the extent of your adjusted tax basis in the Notes. To the extent that such distribution exceeds your adjusted tax basis, it would be treated as capital gain. Such capital gain would be long-term capital gain if your holding period in the Notes exceeds one year as of the date of distribution. Otherwise, such capital gain would be short-term capital gain. Long-term capital gain of a non-corporate U.S. Holder is generally eligible for reduced rates of taxation. The Corporation does not intend to maintain calculations of earnings and profits in a manner necessary to enable U.S. Holders to determine the extent to which a distribution would be treated as a dividend. You should therefore assume that any distribution by the Corporation with respect to the Notes would constitute dividend income.

If you are a non-corporate U.S. Holder, certain dividends paid to you by “qualified foreign corporations” may be taxed at favorable rates. However, these favorable rates are available only if certain conditions are met, including a requirement that you hold the applicable security for a minimum period during which you are not protected from the risk of loss. The IRS has ruled that where a security treated as equity for U.S. federal income tax purposes provides for repayment of the principal amount at maturity, a holder’s creditor rights with respect to the principal repayment may constitute protection from the risk of loss. Therefore, the minimum holding period requirement might not be met with respect to the Notes. If you are a non-corporate U.S. Holder, you should consult your tax adviser with respect to the “qualified dividend income” rules if the Notes are treated as equity for U.S. federal income tax purposes. Interest payments on the Notes will not be eligible for the dividends received deduction generally available to U.S. corporations under the Code with respect to certain dividends.

The amount of dividend income will include any amounts withheld in respect of Canadian taxes and, without duplication, any additional amounts paid with respect thereto.

Interest on the Notes will generally be foreign-source income for foreign tax credit purposes. However, if, as described above, your creditor rights with respect to the principal repayment constitute protection from the risk of loss, you may not be able to meet the minimum holding period necessary to claim foreign tax credits in the case that any Canadian tax is withheld from interest payments.

Sale or Other Taxable Disposition of the Notes

Upon the sale or other taxable disposition of a Note, you will recognize taxable gain or loss equal to the difference between the amount realized on the sale or taxable disposition and your tax basis in the Note. Your tax basis in a Note will generally equal the cost of your Note. Gain or loss, if any, will generally be U.S.-source income or loss for purposes of computing your foreign tax credit limitation. Gain or loss realized on the sale or other taxable disposition of a Note will generally be capital gain or loss and will be long-term capital gain or loss if at the time of the sale or other taxable disposition the Note has been held for more than one year. Long-term capital gains recognized by non-corporate taxpayers are subject to reduced tax rates. The deductibility of capital losses is subject to limitations.

PFIC Rules

In general, the Corporation will be a PFIC for United States federal income tax purposes in any taxable year if (after taking into account the income and assets of Corporation and certain of its subsidiaries) 75% or more of its

S-53

TABLE OF CONTENTS

gross income is passive income, or at least 50% of the average value of its assets is attributable to assets held for the production of, or that produce, passive income. For this purpose, “passive income” generally includes, among other things, interest, dividends, rents, royalties, certain gains from the sale of stock and securities and certain gains from commodities transactions.

PFIC status is determined on an annual basis. The Corporation does not expect to be a PFIC for the taxable year ending December 31, 2022. The determination of whether the Corporation is a PFIC is based on the application of complex U.S. federal income tax rules, which are subject to differing interpretations, and will depend on the composition of the Corporation’s income, expenses and assets from time to time and the nature of its activities. PFIC classification is factual in nature, and generally cannot be determined until the close of the taxable year in question. Consequently, there can be no assurances regarding the PFIC status of the Corporation for its current or any future taxable year. If you own Notes during a taxable year in which the Corporation is a PFIC, the PFIC rules generally will apply to you thereafter, even if in subsequent taxable years the Corporation no longer meets the test described above to be treated as a PFIC. No ruling will be sought from the IRS regarding whether the Corporation is a PFIC.

In general, if the Corporation were to be treated as a PFIC, certain adverse rules would apply to dividends received from the Corporation and to dispositions of the Notes (potentially including dispositions that would not otherwise be taxable), including taxation at maximum ordinary income tax rates plus an interest charge on both gain from the sale of the Notes and certain distributions paid by the Corporation. In addition, in any year in which the Corporation is a PFIC, a U.S. Holder generally must file an annual return on IRS Form 8621, which describes the income received (or deemed to be received in the event you make certain elections (to the extent available)) from the Corporation, any gain realized on a disposition of the Notes and certain other information.

You are urged to consult your tax adviser about the PFIC rules in connection with your holding of the Notes, including potential elections that may be available to mitigate some of the adverse consequences relating to PFIC status.

Conversion Preferred Shares

The discussion under this section generally assumes that we are not, and will not become, a PFIC, as described above.

Dividends

Distributions on the Conversion Preferred Shares will be treated as dividends to the extent paid out of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent that the amount of any distribution exceeds our current and accumulated earnings and profits for a taxable year, the distribution would be treated as a tax-free return of capital to the extent of your adjusted tax basis in the Notes. To the extent that such distribution exceeds your adjusted tax basis, it would be treated as capital gain. Such capital gain would be long-term capital gain if your holding period in the Notes exceeds one year as of the date of distribution. Otherwise, such capital gain would be short-term capital gain. Long-term capital gain of a non-corporate U.S. Holder is generally eligible for reduced rates of taxation. The Corporation does not intend to maintain calculations of earnings and profits in a manner necessary to enable U.S. Holders to determine the extent to which a distribution would be treated as a dividend. You should therefore assume that any distribution by the Corporation with respect to the Notes would constitute dividend income.

If you are a non-corporate U.S. Holder, certain dividends paid to you by “qualified foreign corporations” may be taxed at favorable rates. If the Conversion Preferred Shares are readily tradable on an established U.S. securities market within the meaning of the Code or if the Corporation is eligible for benefits under the income tax treaty between Canada and the United States, we generally would constitute a qualified foreign corporation for U.S. federal income tax purposes and, therefore, distributions on the Conversion Preferred Shares to non-corporate U.S. Holders that are treated as dividends for U.S. federal income tax purposes would be treated as qualified dividend income eligible for such favorable rates, provided the applicable holding period requirements and certain other requirements are met (including, without limitation, the requirement that the Corporation not be classified as a PFIC). Distributions on the Conversion Preferred Shares will not be eligible for the dividends-received deduction generally available to U.S. corporations under the Code with respect to certain dividends. The dividend rules are complex, and each U.S. Holder should consult its own tax adviser regarding the application of such rules.

The amount of dividend income will include any amounts withheld in respect of Canadian taxes.

S-54

TABLE OF CONTENTS

Distributions that are treated as dividends for U.S. federal income tax purposes will generally be foreign-source income for foreign tax credit limitation purposes. As discussed above, withholding of Canadian tax is imposed at a 25% rate (reduced to 15% for recipients that are residents of the U.S. eligible for benefits under the Canada-United States Tax Convention) both on cash and non-cash distributions by us to persons that are not Canadian residents. Such Canadian tax withholding may exceed your allowable foreign tax credit for the taxable year of the distribution. To the extent a refund of the tax withheld is available to you under the laws of Canada or under the Canada-United States Tax Convention, the amount of tax withheld that is refundable will not be eligible for credit against your U.S. federal income tax liability, whether or not the refund is actually obtained. The foreign tax credit limitation rules are complex and dependent on the specific factual circumstances particular to you. Consequently, you should consult your tax adviser as to the U.S. federal income tax consequences relevant to you.

Sale or Other Taxable Disposition of the Conversion Preferred Shares

Upon a sale or other disposition of Conversion Preferred Shares, you generally will recognize gain or loss for U.S. federal income tax purposes equal to the difference between the amount realized and your tax basis in the Conversion Preferred Shares. Gain or loss will generally be capital gain or loss and will be long-term capital gain or loss if at the time of the sale or other taxable disposition the Conversion Preferred Shares have been held for more than one year (including the holding period for the Notes, as applicable). Long-term capital gains recognized by non-corporate taxpayers are subject to reduced tax rates. The deductibility of capital losses is subject to limitations. Gain recognized by you from a sale or other disposition of Conversion Preferred Shares will generally be treated as income from U.S. sources for foreign tax credit limitation purposes.

Backup Withholding and Information Reporting

Information returns may be required to be filed with the IRS in connection with payments on the Notes (and OID, if applicable) and proceeds received from a sale or other disposition of the Notes and dividends received with respect to the Conversion Preferred Shares and proceeds from the disposition of those shares, unless you are an exempt recipient. You may also be subject to backup withholding on these payments in respect of your Notes or Conversion Preferred Shares unless you provide your taxpayer identification number and otherwise comply with applicable requirements of the backup withholding rules or you provide proof of an applicable exemption. Amounts withheld under the backup withholding rules are not additional taxes and may be refunded or credited against your U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

You may be required to report information relating to an interest in the Notes (and OID, if applicable) or Conversion Preferred Shares or an account through which the Notes or Conversion Preferred Shares are held, subject to certain exceptions (including an exception for Notes or Conversion Preferred Shares held in accounts maintained by certain U.S. financial institutions), by attaching a complete IRS Form 8938 to your tax return for each year in which you hold an interest in the Notes or Conversion Preferred Shares. You should consult your tax adviser regarding information reporting requirements relating to your ownership of the Notes or Conversion Preferred Shares.

LEGAL MATTERS

Certain legal matters in connection with the Offering hereunder will be passed upon on behalf of the Corporation by Blake, Cassels & Graydon LLP with respect to Canadian legal matters and by Gibson, Dunn & Crutcher LLP with respect to U.S. legal matters. Certain legal matters in connection with the Offering hereunder will be passed upon on behalf of the Underwriters by Cravath, Swaine & Moore LLP and Bennett Jones LLP. As of the date hereof, the partners and associates of Blake, Cassels & Graydon LLP, as a group, and Bennett Jones LLP, as a group, beneficially own, directly or indirectly, less than 1% of the outstanding securities of the Corporation, respectively.

INDEPENDENT AUDITORS

Ernst & Young LLP, the auditors of the Corporation, have confirmed that they are (i) independent with respect to the Corporation within the meaning of the CPA Code of Professional Conduct of the Chartered Professional Accountants of Ontario and (ii) an independent registered public accounting firm with respect to the Corporation within the meaning of the U.S. Securities Act, the applicable rules and regulations adopted thereunder by the SEC and the Public Company Accounting Oversight Board (United States).

ENFORCEMENT OF CERTAIN CIVIL LIABILITIES

The Corporation is incorporated under the laws of Canada and its registered and head office is in Canada. Some of the Corporation’s directors and most of the Corporation’s officers, and some of the experts named in this Prospectus Supplement, are residents of Canada or otherwise reside outside of the United States, and a portion of their assets, and a portion of the Corporation’s assets, are located outside the U.S. The Corporation has appointed an agent for service of process in the U.S., but it may be difficult for holders of securities who reside in the U.S. to effect service within the U.S. upon the Corporation or those directors, officers and experts who are not residents of the U.S. Investors should not assume that a Canadian court would enforce a judgment of a U.S. court obtained in an action against the Corporation or such other persons predicated on the civil liability provisions of the U.S. federal securities laws or the securities or “blue sky” laws of any state within the U.S. or would enforce, in original actions, liabilities against the Corporation or such persons predicated on the U.S. federal securities laws or any such state securities or “blue sky” laws. The Corporation has been advised by its Canadian counsel, Blake, Cassels & Graydon LLP, that a final and conclusive judgment of a U.S. court, for a sum certain, predicated solely upon civil liability under U.S. federal securities laws would probably be enforceable in Canada if the United States court in which the judgment was obtained has a basis for jurisdiction in the matter that would be recognized by a Canadian court for the same purposes and the United States law that led to the judgment is not contrary to Canadian public policy. The enforceability of a United States judgment in Canada will be subject to applicable limitation periods and may be affected by bankruptcy, insolvency or other laws of general application limiting the enforcement of creditors’ rights generally. The Corporation has also been advised by Blake, Cassels & Graydon LLP, however, that there is a substantial doubt whether an action could be brought in Canada in the first instance on the basis of liability predicated solely upon U.S. federal securities laws.

The Corporation filed with the SEC, concurrently with its registration statement on Form F-10, an appointment of agent for service of process on Form F-X. Under the Form F-X, the Corporation appointed CT Corporation System as its agent for service of process in the U.S. in connection with any investigation or administrative proceeding conducted by the SEC and any civil suit or action brought against or involving the Corporation in a U.S. court arising out of or related to or concerning the offering of securities under the registration statement of which this Prospectus Supplement forms a part.

These statements are based on factors or assumptions that were applied in drawing a conclusion or making a forecast or projection, including assumptions based on historical trends, current conditions and expected future developments. Since forward-looking statements relate to future events and conditions, by their nature they rely on assumptions and involve inherent risks and uncertainties. AQN cautions that although it is believed that the assumptions are reasonable in the circumstances, actual results may differ materially from the expectations set out in the forward-looking statements. Material risk factors and assumptions include those set out in this presentation or contained in AQN’s preliminary prospectus supplement dated the date hereof, AQN’s Management Discussion and Analysis for the three and nine months ended September 30, 2021 (the “Interim MD&A”), AQN’s Management Discussion and Analysis for the three and twelve months ended December 31, 2020 (the “Annual MD&A”), and AQN’s Annual Information Form for the year ended December 31, 2020, each filed with securities regulatory authorities in Canada and the United States. Given these risks, undue reliance should not be placed on these forward-looking statements, which apply only as of their dates. Other than as specifically required by law, AQN undertakes no obligation to update any forward-looking statements to reflect new information, subsequent or otherwise.Non-GAAP Financial MeasuresThe terms "Adjusted Net Earnings", "Adjusted Net Earnings per share" (or "Adjusted Net EPS"), "Adjusted earnings before interest, taxes, depreciation and amortization" ("Adjusted EBITDA") and "Adjusted Funds from Operations" (together, the "Financial Measures") may be used in this presentation and discussion. The Financial Measures are not recognized measures under U.S. GAAP. There is no standardized measure of the Financial Measures; consequently, AQN's method of calculating the Financial Measures may differ from methods used by other companies and therefore they may not be comparable to similar measures presented by other companies. An explanation, calculation and analysis of the Financial Measures and a reconciliation to the most directly comparable U.S. GAAP measure, where applicable, can be found in the Interim MD&A and the Annual MD&A under the headings "Caution Concerning Forward-Looking Statements, Forward-Looking Information and Non-GAAP Measures - Non-GAAP Financial Measures" and “Non-GAAP Financial Measures”, which sections are incorporated by reference herein. The Annual MD&A and Interim MD&A are available on SEDAR at www.sedar.com and EDGAR at www.sec.gov. A reconciliation of certain of the Financial Measures used in the presentation to the most directly comparable U.S. GAAP measure can also be found in the Appendix to this presentation.Market and Industry Data Certain of the information contained in this presentation concerning economic trends and market, peer and industry data and projections is based upon or derived from information by third party or industry sources. The Company provides no assurance with respect to the accuracy of such information nor has the Company independently verified such information or the assumptions upon which projections of future trends are based.

DESCRIPTION OF DEBT SECURITIES

In this section, “the Corporation” refers only to Algonquin Power & Utilities Corp. and not the direct or indirect subsidiary entities of Algonquin Power & Utilities Corp. or partnership interests held by Algonquin Power & Utilities Corp. or its subsidiary entities.

The following describes certain general terms and provisions of the Debt Securities. The particular terms and provisions of a series of Debt Securities offered pursuant to any Prospectus Supplement, and the extent to which the general terms and provisions described below may apply to such Debt Securities, will be described in the Prospectus Supplement filed in respect of such Debt Securities.

The Debt Securities will be direct unsecured obligations of the Corporation and will be senior or subordinated indebtedness of the Corporation as described in the applicable Prospectus Supplement. The Debt Securities may be offered separately or together with other Securities. The Debt Securities will be issued under one or more indentures (each, a “Trust Indenture”) in each case between the Corporation and a trustee (or a U.S. trustee and a Canadian co-trustee) (an “Indenture Trustee”), determined by the Corporation in accordance with applicable laws. Any Debt Securities offered or sold to persons in the U.S. pursuant to this Prospectus will be issued under a Trust Indenture substantially in the form of one of the Trust Indentures filed with the SEC as an exhibit to the Corporation’s

TABLE OF CONTENTS

registration statement of which this Prospectus is a part. A copy of any Trust Indenture or supplement thereto entered into by the Corporation will be filed with securities regulatory authorities and will be available on the Corporation’s SEDAR profile at www.sedar.com. The statements made below relating to the Trust Indenture and the Debt Securities to be issued thereunder are summaries of certain anticipated provisions thereof, are not complete and are subject to, and are qualified in their entirety by reference to, all provisions of the applicable Trust Indenture.

The Corporation conducts its business primarily through its subsidiaries. Accordingly, the ability of the Corporation to meet its obligations under the Debt Securities is dependent primarily on the earnings and cash flows of those subsidiaries and the ability of those subsidiaries to pay dividends or to advance or repay funds to the Corporation. The Corporation’s subsidiaries are separate legal entities and have no independent obligation to pay dividends. Prior to paying dividends, the subsidiaries have financial obligations that must be satisfied, including among others, their operating expenses and obligations to creditors. Furthermore, subsidiaries which are regulated utilities are required by regulation to maintain a minimum equity-to-total capital ratio that may restrict their ability to pay dividends to the Corporation or may require that the Corporation contribute capital. In the future, laws or regulations may be enacted that prohibit or further restrict the ability of the subsidiaries to pay upstream dividends or to repay intercorporate indebtedness. In addition, the rights that the Corporation and its creditors would have to participate in the assets of any such subsidiary upon the subsidiary’s liquidation or recapitalization will be subject to the prior claims of the subsidiary’s creditors. Certain subsidiaries have incurred substantial amounts of debt in the operation and expansion of their businesses, and it is anticipated that certain subsidiaries will continue to do so in the future.

Holders of Debt Securities will generally have a junior position to claims of creditors of the Corporation’s subsidiaries, including trade creditors, debt holders, secured creditors, taxing authorities, guarantee holders and any holders of preference or preferred shares. In addition to trade debt, certain operating subsidiaries have ongoing corporate debt programs used to finance their business activities. The Debt Securities will be effectively subordinated to any existing and future secured obligations to the extent of the value of the collateral securing such obligations. The Debt Securities will be structurally subordinated to all liabilities and any preference or preferred shares of the Corporation’s subsidiaries.

Unless otherwise specified in a Prospectus Supplement, the Trust Indentures will not limit the amount of indebtedness or preference or preferred shares issuable by the Corporation or its subsidiaries.

The following description of the Debt Securities is only a summary and is not intended to be comprehensive. For additional information you should refer to the Trust Indenture under which such Debt Securities are issued.

General

The Trust Indentures will not limit the amount of Debt Securities that may be issued thereunder. The Corporation may issue Debt Securities from time to time under a Trust Indenture in one or more series by entering into supplemental indentures or by its board of directors or a duly authorized committee authorizing the issuance. The Debt Securities of a series need not be issued at the same time, bear interest at the same rate or mature on the same date.

The Prospectus Supplement for a particular series of Debt Securities will disclose the specific terms of such Debt Securities, including the price or prices at which the Debt Securities to be offered will be issued. Those terms may include some or all of the following:

Debt Securities represented by instalment receipts will not be offered or sold to persons in the U.S. pursuant to this Prospectus.

DESCRIPTION OF SHARE PURCHASE CONTRACTS

AND SHARE PURCHASE OR EQUITY UNITS

The Corporation may issue share purchase contracts, including contracts obligating holders to purchase from the Corporation, and the Corporation to sell to the holders, a specified number of Equity Securities, at a future date or dates, or similar contracts issued on a “prepaid” basis (in each case, “Share Purchase Contracts”).

The Share Purchase Contracts may be issued separately or as part of units consisting of a Share Purchase Contract and Debt Securities or obligations of third parties (including U.S. treasury securities) (the “Share Purchase or Equity Units”), and may or may not serve as collateral for a holder’s obligations. The Share Purchase Contracts may require holders to secure their obligations thereunder in a specified manner. The Share Purchase Contracts also may require the Corporation to make periodic payments to the holders of the Share Purchase Contracts or vice versa, and such payments may be unsecured or refunded on some basis.

The applicable Prospectus Supplement will describe the terms of the Share Purchase Contracts or Share Purchase or Equity Units. The description in the applicable Prospectus Supplement will not necessarily be complete, and reference will be made to the Share Purchase Contracts, and, if applicable, collateral, depositary or custodial arrangements, relating to the Share Purchase Contracts or Share Purchase or Equity Units. Material United States and Canadian federal income tax considerations applicable to the holders of the Share Purchase or Equity Units and the Share Purchase Contracts will also be discussed in the applicable Prospectus Supplement.

The particular terms and provisions of the Units offered pursuant to a Prospectus Supplement, and the extent to which the general terms described below apply to those Units, will be described in such Prospectus Supplement. The following description and any description of Units in the applicable Prospectus Supplement does not purport to be complete and is subject to and qualified in its entirety by reference to any agreement, collateral arrangements and depositary arrangements relating to such Units.

The Corporation may issue Units comprised of one or more of the Securities described in this Prospectus in any combination, including fractions of such Securities. Each Unit will be issued so that the holder of the Unit is also the holder of each Security included in the Unit. Thus, the holder of a Unit will have the rights and obligations of a holder of each included Security. The unit agreement (if any) under which a Unit is issued may provide that the Securities included in the Unit may not be held or transferred separately, at any time or at any time before a specified date.

Any Prospectus Supplement for Units will contain the terms and other information with respect to the Units being offered thereby, including:

(a)	the designation and terms of the Units and of the Securities comprising the Units, including whether and under what circumstances those Securities may be held or transferred separately;

(b)	any provisions for the issuance, payment, settlement, transfer or exchange of the Units or of any Securities comprising the Units;

TABLE OF CONTENTS

(c)	whether the Units will be issued in fully registered or “book-entry only” form; and

(d)	any other material terms and conditions of the Units.

BOOK-ENTRY ONLY SECURITIES

Securities issued in “book-entry only” form must be purchased, transferred or redeemed through participants in the depository service of a depository identified in a Prospectus Supplement for the particular offering of Securities. Each of the underwriters, dealers, remarketing firms or agents, as the case may be, named in an accompanying Prospectus Supplement will be a participant of the depository or will have arrangements with a participant. On the closing of a book-entry only offering, the Corporation may cause a global certificate or certificates representing the aggregate number of Securities subscribed for under such offering to be delivered to, and registered in the name of, the depository or its nominee. Except as described below, no purchaser of Securities will be entitled to a certificate or other instrument from the Corporation or the depository evidencing that purchaser’s ownership thereof, and no purchaser will be shown on the records maintained by the depository except through a book-entry account of a participant acting on behalf of such purchaser. Each purchaser of Securities will receive a customer confirmation of purchase from the registered dealer from which the Securities are purchased in accordance with the practices and procedures of that registered dealer. The practices of registered dealers may vary, but generally customer confirmations are issued promptly after execution of a customer order. The depository will be responsible for establishing and maintaining book-entry accounts for its participants having interests in the Securities. Reference in this Prospectus to a holder of Securities means, unless the context requires otherwise, the owner of the beneficial interest in the Securities.

If the Corporation determines, or the depository notifies the Corporation in writing, that the depository is no longer willing or able to discharge properly its responsibilities as depository with respect to the Securities and the Corporation is unable to locate a qualified successor, or if the Corporation at its option elects, or is required by law, to terminate the book-entry system, then the Securities will be issued in fully registered form to holders or their nominees.

Transfer, Conversion or Redemption of Securities

Transfer of ownership, conversion or redemption of Securities will be effected through records maintained by the depository or its nominee for such Securities with respect to interests of participants, and on the records of participants with respect to interests of persons other than participants. Holders who desire to purchase, sell or otherwise transfer ownership of or other interests in the Securities may do so only through participants.

The ability of a holder to pledge a Security or otherwise take action with respect to such holder’s interest in a Security (other than through a participant) may be limited due to the lack of a physical certificate.

Payments and Notices

Payments of principal, redemption price, if any, dividends and interest, as applicable, on each Security will be made by the Corporation to the depository or its nominee, as the case may be, as the registered holder of the Security and the Corporation understands that such payments will be credited by the depository or its nominee in the appropriate amounts to the relevant participant. Payments to holders of Securities of amounts so credited will be the responsibility of the participants.

As long as the depository or its nominee is the registered holder of the Securities, the depository or its nominee, as the case may be, will be considered the sole owner of the Securities for the purposes of receiving notices or payments on the Securities. In such circumstances, the responsibility and liability of the Corporation in respect of notices or payments on the Securities is limited to giving or making payment of any principal, redemption price, if any, dividends and interest due on the Securities to the depository or its nominee.

Each holder must rely on the procedures of the depository and, if such holder is not a participant, on the procedures of the participant through which such holder owns its interest, to exercise any rights with respect to the Securities. The Corporation understands that under existing industry practices, if the Corporation requests any action of holders or if a holder desires to give any notice or take any action which a registered holder is entitled to give or take with respect to the Securities, the depository would authorize the participant acting on behalf of the holder to give such notice or to take such action, in accordance with the procedures established by the depository or agreed

TABLE OF CONTENTS

to from time to time by the Corporation, any Indenture Trustee, warrant agent, subscription receipt agent, collateral agent, purchase contract agent or custodial agent and depository. Any holder that is not a participant must rely on the contractual arrangement it has directly, or indirectly through its financial intermediary, with its participant to give such notice or take such action.

The Corporation, the remarketing firms, the underwriters or agents and any Indenture Trustee identified in an accompanying Prospectus Supplement, as applicable, will not have any liability or responsibility for (i) records maintained by the depository relating to beneficial ownership interest in the Securities held by the depository or the book-entry accounts maintained by the depository; (ii) maintaining, supervising or reviewing any records relating to any such beneficial ownership interest; or (iii) any advice or representation made by or with respect to the depository and contained herein or in any Trust Indenture with respect to the rules and regulations of the depository or at the directions of the participants.

Unless otherwise specified in the applicable Prospectus Supplement, each series or issue of Debt Securities, Subscription Receipts, Warrants, Share Purchase Contracts, Share Purchase or Equity Units and Units will be a new issue of securities with no established trading market. Unless otherwise specified in a Prospectus Supplement relating to an issue of such Securities, such Securities will not be listed on any securities or stock exchange.

Subject to any applicable securities legislation, and other than in relation to an “at-the-market distribution”, in connection with any offering of Securities, the underwriters, dealers or agents may over-allot or effect transactions which stabilize, maintain or otherwise affect the market price of the Securities at a level above that which otherwise might prevail on the open market. Such transactions may be commenced, interrupted or discontinued at any time. Any underwriters or agents to or through whom Securities are sold by the Corporation may make a market in the Securities, but they will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given that a trading market in any of the Securities (other than Equity Securities) will develop or as to the liquidity of any trading market for the Securities.

No underwriter or agent of an “at-the-market distribution” under this Prospectus, no affiliate of such underwriter or agent, and no person or company acting jointly or in concert with such underwriter or agent will, in connection with the distribution, over-allot securities or effect any other transaction that is intended to stabilize or maintain the market price of the Securities or securities of the same class as the securities distributed under this Prospectus, including selling an aggregate number or principal amount of securities that would result in the underwriter or agent creating an over-allocation position in the Securities.

ENFORCEMENT OF CERTAIN CIVIL LIABILITIES

TABLE OF CONTENTS

a portion of the Corporation’s assets, are located outside the U.S. The Corporation has appointed an agent for service of process in the U.S. but it may be difficult for holders of Securities who reside in the U.S. to effect service within the U.S. upon the Corporation or those directors, officers and experts who are not residents of the U.S. Investors should not assume that a Canadian court would enforce a judgment of a U.S. court obtained in an action against the Corporation or such other persons predicated on the civil liability provisions of the U.S. federal securities laws or the securities or “blue sky” laws of any state within the U.S. or would enforce, in original actions, liabilities against the Corporation or such persons predicated on the U.S. federal securities laws or any such state securities or “blue sky” laws. The Corporation has been advised by its Canadian counsel, Blake, Cassels & Graydon LLP, that a judgment of a U.S. court predicated solely upon civil liability under U.S. federal securities laws would probably be enforceable in Canada if the United States court in which the judgment was obtained has a basis for jurisdiction in the matter that would be recognized by a Canadian court for the same purposes. The Corporation has also been advised by Blake, Cassels & Graydon LLP, however, that there is a substantial doubt whether an action could be brought in Canada in the first instance on the basis of liability predicated solely upon U.S. federal securities laws.
