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.

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:

The Debt Securities offered pursuant to this Prospectus and any Prospectus Supplement may be represented by instalment receipts which will provide for payment for the Debt Securities on an instalment basis, the particular terms and provisions of which will be described in the applicable Prospectus Supplement and set out in an instalment receipt and pledge agreement or similar agreement. Any such instalment receipt will evidence, among other things, (a) the fact that a first instalment payment has been made in respect of the Debt Securities represented thereby and (b) the beneficial ownership of the Debt Securities represented by the instalment receipt, subject to a pledge of such Debt Securities securing the obligation to pay the balance outstanding under such Debt Securities on or prior to a certain date. Debt Securities represented by instalment receipts will not be offered or sold to persons in the U.S. pursuant to this Prospectus. A copy of any such instalment receipt and pledge agreement or similar agreement will be filed by the Corporation with securities regulatory authorities after it has been entered into and will be available on the Corporation’s SEDAR profile at www.sedar.com.

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 particular terms and provisions of Subscription Receipts offered pursuant to any Prospectus Supplement, and the extent to which the general terms and provisions described below may apply thereto, will be described in the Prospectus Supplement filed in respect of such Subscription Receipts. This description will include, where applicable:

Subscription Receipts may be offered separately or in combination with one or more other Securities. The Subscription Receipts will be issued under a subscription receipt agreement. A copy of the subscription receipt agreement will be filed by the Corporation with the securities regulatory authorities in each of the provinces and territories of Canada and with the SEC in the U.S. after it has been entered into by the Corporation and will be available electronically at www.sedar.com.

The Corporation has adopted a shareholder rights plan as amended, restated and continued as of June 6, 2019 and approved by shareholders on June 9, 2019. A copy of the shareholder rights plan has been filed with the applicable securities regulatory authorities in Canada and is available electronically at www.sedar.com. For additional information on the shareholder rights plan, see “Shareholders’ Rights Plan” in the AIF.

The Corporation is authorized to issue an unlimited number of Preferred Shares, issuable in one or more series, containing terms and conditions as approved by the board of directors of the Corporation, which may include voting rights. The Preferred Shares of each series will rank equally with the Preferred Shares of every other series and will rank in priority to the Common Shares with respect to dividends and return of capital in the event of liquidation, dissolution or winding up of the Corporation.

The articles of the Corporation, which include the terms of the Series A Preferred Shares, the Series B Preferred Shares, the Series C Preferred Shares, the Series D Preferred Shares, the Series E Preferred Shares, the Series F Preferred Shares and the Series G Preferred Shares, are available on the Corporation’s SEDAR profile at www.sedar.com. For a detailed description of the terms and conditions of the Corporation’s existing series of Preferred Shares, see “Description of Capital Structure” in the AIF. The specific terms of any series of Preferred Shares to be issued hereunder will be as described in a Prospectus Supplement. Accordingly, the statements made or incorporated by reference in this section may not apply to a particular series of Preferred Shares.

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 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 price per Equity Security and the number of Equity Securities may be fixed at the time the Share Purchase Contracts are issued or may be determined by reference to a specific formula set forth in the Share Purchase Contracts. The Share Purchase Contracts will require either that the share purchase price be paid at the time the Share Purchase Contracts are issued or that payment(s) be made at a specified future date(s). 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.

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 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 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

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.

NI 44-102, including sales made directly on the TSX and the NYSE or other existing trading markets for the Securities), at prices determined by reference to the prevailing price of a specified security in a specified market or at prices to be negotiated with purchasers, in which case the compensation payable to an underwriter, dealer or agent in connection with any such sale will be decreased by the amount, if any, by which the aggregate price paid for the Securities by the purchasers is less than the gross proceeds paid by the underwriter, dealer or agent to the Corporation. The price at which the Securities will be offered and sold may vary from purchaser to purchaser and during the period of distribution.

The Prospectus Supplement for any of the Securities being offered thereby will set forth the terms of the offering of such Securities, including the name or names of any underwriters, dealers or agents, the purchase price of such Securities, the proceeds to the Corporation from such sale, any underwriting discounts or commissions and other items constituting underwriters’ or agents’ compensation, any public offering price and any discounts or concessions allowed or re-allowed or paid by any underwriter to other dealers. Only underwriters so named in the Prospectus Supplement are deemed to be underwriters in connection with the Securities offered thereby.

If underwriters are used in the sale, the Securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale, at market prices prevailing at the time of sale or at prices related to such prevailing market prices. The obligations of the underwriters to purchase such Securities will be subject to certain conditions precedent, and the underwriters will be obligated to purchase all the Securities offered pursuant to the applicable Prospectus Supplement if any of such Securities are purchased. Any public offering price and any discounts or concessions allowed or re-allowed or paid to underwriters, dealers or agents may be changed from time to time.

The Securities may also be sold (i) directly by the Corporation at such prices and upon such terms as agreed to by the Corporation and the purchasers or (ii) through agents designated by the Corporation from time to time. Any agent involved in the offering and sale of the Securities in respect of which this Prospectus is delivered will be named, and any commissions payable by the Corporation to such agent will be set forth, in the applicable Prospectus Supplement. Unless otherwise indicated in the applicable Prospectus Supplement, any agent is acting on a best efforts basis for the period of its appointment.

The Corporation may agree to pay the underwriters or agents a commission for various services relating to the issue and sale of any Securities offered hereby. Any such commission will be paid out of the general corporate funds of the Corporation. Underwriters, remarketing firms and agents who participate in the distribution of the Securities may be entitled under agreements to be entered into with the Corporation to indemnification by the Corporation against certain liabilities, including liabilities under the U.S. Securities Act and Canadian securities legislation, or to contribution with respect to payments which such underwriters, remarketing firms or agents may be required to make in respect thereof.

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.

Securities may also be offered and sold, if so indicated in the applicable Prospectus Supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more firms, which we refer to herein as the “remarketing firms”, acting as principals for their own account or as agents of the Corporation. Any remarketing firm will be identified and the terms of its agreement, if any, with the Corporation, and its compensation will be described in the applicable Prospectus Supplement. Remarketing firms may be deemed to be underwriters in connection with the remarketing of the Securities.

Unless otherwise specified in a Prospectus Supplement, the Securities will not be registered under the U.S. Securities Act.

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.

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.

A copy of the form of warrant indenture and subscription receipt agreement, as applicable, will be filed by post-effective amendment or by incorporation by reference to documents filed with, or furnished to, the SEC under the U.S. Exchange Act.

Pursuant to the requirements of Section 6(a) of the Securities Act, as amended, the undersigned has signed this Registration Statement solely in the capacity of the duly authorized representative of Algonquin Power & Utilities Corp. in the United States on November 12, 2021.
