Cenovus Energy Inc.

Debt Securities

Common Shares

Preferred Shares

Subscription Receipts

Warrants

Share Purchase Contracts

Units

We may from time to time offer and sell our debentures, notes or other evidence of indebtedness of any kind, nature or description and which may be issuable in series (collectively, “debt securities”), common shares, preferred shares, subscription receipts, warrants, share purchase contracts and units (collectively, debt securities, common shares, preferred shares, subscription receipts, warrants, share purchase contracts and units are referred to in this prospectus as the “Securities”) during the 25-month period that this short form base shelf prospectus, including any amendments hereto (this “prospectus”), remains valid. Certain current or future holders of our securities (collectively, the “Selling Securityholders”) may also offer and sell certain Securities from time to time pursuant to this prospectus. See “Selling Securityholders”.

Securities may be offered separately or together, in amounts, at prices and on terms to be determined based on market conditions at the time of sale and set forth in one or more prospectus supplements (each, a “prospectus supplement”). The Securities may be offered and sold in Canada and/or the United States and elsewhere where permitted by law. We will provide the specific terms of the Securities in prospectus supplements to this prospectus that will be delivered to purchasers together with this prospectus. Unless otherwise provided in a prospectus supplement relating to a series of debt securities, the debt securities will be our direct, unsecured and unsubordinated obligations and will be issued under a trust indenture. You should read this prospectus and any prospectus supplement carefully before you invest in any of the Securities.

NEITHER THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION (THE “SEC”) NOR ANY STATE SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED THESE SECURITIES OR PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE.

We are permitted, under a multijurisdictional disclosure system adopted by the United States and Canada, to prepare this prospectus in accordance with Canadian disclosure requirements, which are different from those of the United States. We prepare our financial statements in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board, which are generally accepted accounting principles (“GAAP”) for publicly accountable enterprises in Canada. Our financial statements, which are subject to United States auditing and auditor independence standards, may not be comparable to financial statements of United States companies.

Certain data relating to our reserves included in or incorporated by reference in this prospectus has been prepared in accordance with Canadian disclosure standards, which are not comparable in all respects to United States disclosure standards. See “Note Relating to Reserves Disclosure”.

Owning the Securities may subject you to tax consequences both in the United States and Canada. This prospectus or any applicable prospectus supplement may not describe these tax consequences fully. You should read the tax discussion in any applicable prospectus supplement. See “Certain Income Tax Considerations”.

The enforcement by investors of civil liabilities under the United States federal securities laws may be affected adversely because we are organized under the laws of Canada. Most of our directors and officers, and some or all of the experts named in this prospectus, are residents of Canada or otherwise reside outside of the United States, and a substantial portion of their assets, and a substantial portion of our assets, are located outside the United States. See “Enforceability of Civil Liabilities”.

Investment in the Securities involves certain risks that should be considered by a prospective purchaser. See “Risk Factors” along with the risk factors described in the applicable prospectus supplement pertaining to a distribution of Securities and the risk factors described in the documents incorporated by reference in this prospectus. See “Where You Can Find More Information”.

All shelf information permitted under applicable law to be omitted from this prospectus will be contained in one or more prospectus supplements that will be delivered to prospective purchasers together with this prospectus, such delivery to be effected in the case of United States purchasers through the filing of such prospectus supplement or prospectus supplements with the SEC. Each prospectus supplement will be incorporated by reference into this prospectus for the purposes of applicable securities laws as of the date of the prospectus supplement and only for the purposes of the distribution of the Securities to which the prospectus supplement pertains.

We may sell the Securities and the Selling Securityholders may sell certain Securities to or through underwriters or dealers, directly to one or more purchasers or through agents. See “Plan of Distribution”. This prospectus may qualify an “at-the-market distribution”, as defined in National Instrument 44-102 – Shelf Distributions (“NI 44-102”) (an “at-the-market distribution”), provided that the requirements of Part 9 of NI 44-102 are complied with in connection with the filing of a prospectus supplement for an at-the-market distribution. The prospectus supplement relating to a particular offering of Securities will identify each underwriter, dealer or agent, as the case may be, engaged by us and/or the Selling Securityholders in connection with the offering and sale of Securities, and will set forth the terms of the offering of such Securities, including the method of distribution of such Securities, the public offering price, the proceeds to us and/or the Selling Securityholders, any fees, discounts or other compensation payable to underwriters, dealers or agents, and any other material terms of the plan of distribution. Securities may be sold from time to time in one or more transactions at a fixed price or fixed prices, or at non-fixed prices. If offered on a non-fixed price basis, Securities may be offered at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at prices to be negotiated with purchasers, including sales in transactions that are deemed to be at-the-market distributions, including sales made directly on the Toronto Stock Exchange (the “TSX”), the New York Stock Exchange (the “NYSE”) or other existing trading markets for the Securities, and as set forth in the applicable prospectus supplement. If offered on a non-fixed price basis, the price per Security may vary between purchasers and during the period of distribution. If Securities are offered on a non-fixed price basis, the underwriters’, dealers’ or agents’ compensation will be increased or decreased by the amount by which the aggregate price paid for Securities by the purchasers exceeds or is less than the gross proceeds paid by the underwriters, dealers or agents to us, or in the case of Securities offered by the Selling Securityholders, to the Selling Securityholders. See “Plan of Distribution”.

Subject to applicable laws, in connection with any offering of Securities, other than an at-the-market distribution, the underwriters or agents, as the case may be, may over-allot or conduct transactions intended to stabilize, maintain or otherwise affect the market price for the Securities at levels other than those which otherwise might prevail in the open market. Such transactions may be commenced, interrupted or discontinued at any time. A purchaser who acquires Securities forming part of the underwriters’ over-allocation position acquires those securities under this prospectus, regardless of whether the over-allocation position is ultimately filled through the exercise of the overallotment option or secondary market purchases. However, no underwriter or

ii

dealer involved in an at-the-market distribution, no affiliate of such an underwriter or dealer and no person or company acting jointly or in concert with such an underwriter or dealer will over-allot Securities in connection with such distribution or effect any other transactions that are intended to stabilize or maintain the market price of the Securities. See “Plan of Distribution”.

Our common shares are listed on the TSX and the NYSE under the symbol “CVE”. On November 2, 2023, the last completed trading day prior to the date of this prospectus, the closing price of the common shares on the TSX and NYSE was $26.75 and US$19.52 per common share, respectively. Our outstanding preferred shares, Series 1, Series 2, Series 3, Series 5 and Series 7 are listed on the TSX under the symbols “CVE.PR.A”, “CVE.PR.B”, “CVE.PR.C”, “CVE.PR.E” and “CVE.PR.G”, respectively. On November 2, 2023, the last completed trading day prior to the date of this prospectus, the closing prices of the Series 1, Series 2, Series 3, Series 5 and Series 7 preferred shares on the TSX were $12.98, $15.05, $19.15, $18.64 and $18.72, respectively. We also have outstanding warrants that are listed on the TSX under the symbol “CVE.WT” and the NYSE under the symbol “CVE WS”. On November 2, 2023, the last completed trading day prior to the date of this prospectus, the closing price of these warrants on the TSX and NYSE was $20.27 and US$14.72 per warrant, respectively.

Unless otherwise specified in the applicable prospectus supplement, the debt securities, preferred shares, subscription receipts, warrants, share purchase contracts and units will not be listed on any securities or stock exchange and there is no market through which the debt securities, preferred shares, subscription receipts, warrants, share purchase contracts and units may be sold and purchasers may not be able to resell such securities purchased under this prospectus and the applicable prospectus supplement. This may affect the pricing of the debt securities, preferred shares, subscription receipts, warrants, share purchase contracts and units in the secondary market, the transparency and availability of trading prices, the liquidity of the debt securities, preferred shares, subscription receipts, warrants, share purchase contracts and units and the extent of issuer regulation. See “Risk Factors”.

As of the date hereof, we have determined that we qualify as a “well-known seasoned issuer” under the WKSI Blanket Orders (as defined herein). See “Reliance on Exemptions for Well-Known Seasoned Issuers”.

Mr. Keith M. Casey, Mr. James D. Girgulis, Ms. Melanie A. Little, Mr. Richard J. Marcogliese, Mr. Frank J. Sixt and Ms. Rhonda I. Zygocki are directors of Cenovus who reside outside of Canada.

This cautionary statement qualifies all forward-looking information contained in this prospectus or incorporated by reference in this prospectus.

NOTE RELATING TO RESERVES DISCLOSURE

The securities regulatory authorities in Canada have adopted National Instrument 51-101 — Standards of Disclosure for Oil and Gas Activities (“NI 51-101”), which imposes oil and gas disclosure standards for Canadian public issuers engaged in oil and gas activities. NI 51-101 permits oil and gas issuers, in their filings with Canadian securities regulatory authorities, to disclose proved and probable reserves, and to disclose reserves and production on a gross basis before deducting royalties. Proved reserves are reserves that can be estimated with a high degree of certainty to be recoverable. Probable reserves are those additional reserves that are less certain to be recovered.

We are permitted to disclose reserves in accordance with Canadian securities law requirements and the disclosure in certain of the documents incorporated by reference herein includes reserves designated as probable reserves.

The SEC definitions of proved and probable reserves are different from the definitions contained in NI 51-101; therefore, proved and probable reserves disclosed in the documents incorporated by reference herein in compliance with NI 51-101 may not be comparable to United States standards. The SEC requires United States oil and gas reporting companies, in their filings with the SEC, to disclose only proved reserves after the deduction of royalties and production due to others but permits the optional disclosure of probable reserves.

As permitted by NI 51-101, we have determined and disclosed the net present value of future net revenue from our reserves in our NI 51-101 compliant reserves disclosure using forecast prices and costs. The SEC requires that reserves and related future net revenue be estimated based on historical 12 month average prices, but permits the optional disclosure of revenue estimates based on different price and cost criteria, including standardized future prices.

For additional information regarding the presentation of our reserves and other oil and gas information, see the section entitled “Reserves Data and Other Oil and Gas Information” in the AIF, which is incorporated by reference herein.

ENFORCEABILITY OF CIVIL LIABILITIES

We are a corporation incorporated under and governed by the Canada Business Corporations Act. Most of our directors and officers, and some or all of the experts named in this prospectus, are residents of Canada or otherwise reside outside of the United States, and a substantial portion of their assets, and a substantial portion of our assets, are located outside the United States. We have appointed an agent for service of process in the United States, but it may be difficult for holders of securities who reside in the United States to effect service within the United States upon those directors, officers and experts who are not residents of the United States. It may also be difficult for holders of securities who reside in the United States to realize in the United States upon judgments of courts of the United States predicated upon our civil liability and the civil liability of our directors and officers and experts under the United States federal securities laws. We have been advised by our Canadian counsel, Blake, Cassels & Graydon LLP, that a judgment of a United States court predicated solely upon civil liability under United States 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. We have also been advised by Blake, Cassels & Graydon LLP, however, that there is a real doubt whether an action could be brought in Canada in the first instance on the basis of liability predicated solely upon United States federal securities laws.

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

We are subject to the informational requirements of the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”), and, in accordance with the Exchange Act, we also file reports with and furnish other information to the SEC. Under the multijurisdictional disclosure system adopted by the United States and Canada, these reports and other information (including financial information) may be prepared, in part, in accordance with the disclosure requirements of the provincial and territorial securities regulatory authorities of Canada, which differ from those in the United States. Our filings are also electronically available from the SEC’s Electronic Data Gathering, Analysis and Retrieval (EDGAR) system, which can be accessed at www.sec.gov, as well as from commercial document retrieval services.

Under applicable securities laws in Canada and the United States, we are permitted to incorporate by reference certain information that we file with the securities commissions or similar authorities in Canada and

with the SEC, which means that we can disclose important information to you by referring you to those documents. Information that is incorporated by reference is an important part of this prospectus. We incorporate by reference the documents listed below, which were filed with the securities commission or similar authority in each of the provinces and territories of Canada under Canadian securities legislation:

Any statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute part of this prospectus. The modifying or superseding statement need not state that it has modified or superseded a prior statement or include any other information set forth in the document which it modifies or supersedes. The making of a modifying or superseding statement is not to be deemed an admission for any purposes that the modified or superseded statement, when made, constituted a misrepresentation, an untrue statement of a material fact or an omission to state a material fact that is required to be stated or that is necessary to make a statement not misleading in light of the circumstances in which it was made.

CENOVUS ENERGY INC.

Cenovus is a Canadian-based integrated energy company headquartered in Calgary, Alberta. Our common shares and common share purchase warrants are listed on the TSX and NYSE. Our cumulative redeemable

8

preferred shares series 1, 2, 3, 5 and 7 are listed on the TSX. We are the second largest Canadian-based crude oil and natural gas producer, with upstream operations in Canada and the Asia Pacific region, and the second largest Canadian-based refiner and upgrader, with downstream operations in Canada and the United States.

Our downstream operations include upgrading and refining operations in Canada and the United States, and commercial fuel operations across Canada.

Our operations involve activities across the full value chain to develop, produce, refine, transport and market crude oil, natural gas and refined petroleum products in Canada and internationally. Our physically integrated upstream and downstream operations help us mitigate the impact of volatility in light-heavy crude oil differentials and contribute to our net earnings by capturing value from crude oil and natural gas production through to the sale of finished products such as transportation fuels.

CONSOLIDATED CAPITALIZATION

Since September 30, 2023, there have been no material changes in our share and loan capital, on a consolidated basis.

USE OF PROCEEDS

Unless otherwise indicated in the applicable prospectus supplement, we will use the net proceeds we receive from the sale of the Securities for general corporate purposes. Those general corporate purposes may include capital expenditures, the repayment of indebtedness and the financing of acquisitions. The amount of net proceeds to be used for any such purpose will be described in the applicable prospectus supplement. We may invest funds that we do not immediately require in short-term marketable securities. The Selling Securityholders will not, directly or indirectly, receive any proceeds from any offering of Securities by us under this prospectus. We will not, directly or indirectly, receive any proceeds from any sale of Securities by the Selling Securityholders.

DESCRIPTION OF DEBT SECURITIES

In this section only, “we”, “us”, “our” or “Cenovus” refer only to Cenovus Energy Inc. without any of its subsidiaries or partnerships through which it operates. The following description describes certain general terms and provisions of the debt securities.

We may issue debt securities either separately or together with or upon the conversion of or in exchange for other Securities. The particular terms and provisions of each series of debt securities we may offer, including any conversion or exchange rights attaching to the debt securities, will be described in greater detail in the applicable prospectus supplement which may provide information that is different from this prospectus. We reserve the right to include in a prospectus supplement specific variable terms pertaining to the debt securities that are not within the descriptions set forth in this prospectus. To the extent that any terms or provisions or other information described in this prospectus differ from any of the terms or provisions or other information described in a prospectus supplement, the description set forth in this prospectus shall be deemed to have been superseded by the description set forth in the prospectus supplement with respect to those debt securities.

Debt securities offered pursuant to this prospectus may be issued under an indenture dated August 17, 2012 between us and The Bank of New York Mellon, as “Trustee” (as supplemented from time to time, the

9

“Indenture”). The Indenture is subject to and governed by the United States Trust Indenture Act of 1939, as amended. We may also, from time to time, issue debt securities and incur additional indebtedness pursuant to this prospectus under one or more indentures other than the Indenture as may be described in the applicable prospectus supplement.

General

The applicable prospectus supplement relating to a distribution of debt securities to be issued under the Indenture or otherwise, will disclose the specific terms of such debt securities. Those terms may include some or all of the following:

10

In addition to new issues of debt securities, this prospectus may be used in connection with the remarketing of outstanding debt securities, in which case the terms of the remarketing and of the remarketed debt securities will be set forth in the applicable prospectus supplement. See “Plan of Distribution”.

DESCRIPTION OF SHARE CAPITAL

The following sets forth the terms and provisions of our existing capital. The particular terms and provisions of the common shares and/or preferred shares offered by a prospectus supplement and the extent to which these general terms and provisions apply will be described in such prospectus supplement. Cenovus is authorized to issue: (i) an unlimited number of common shares; and (ii) first preferred shares and second preferred shares (collectively, the “preferred shares”) up to an aggregate number not to exceed 20% of the aggregate number of common shares then outstanding.

Common Shares

The following description is subject to, and qualified by reference to, the terms and provisions of our articles and by-laws.

The holders of common shares are entitled: (i) to receive dividends if, as and when declared by the board of directors of Cenovus (the “Board”); (ii) to receive notice of, to attend, and to vote on the basis of one vote per common share held, at all meetings of shareholders; and (iii) to participate in any distribution of Cenovus’s assets in the event of liquidation, dissolution or winding up or other distribution of Cenovus’s assets among its shareholders for the purpose of winding up its affairs.

The declaration of dividends is at the sole discretion of the Board and is considered each quarter. All dividends will be reviewed by the Board and may be increased, reduced or suspended from time to time. Our ability to pay dividends and the actual amount of such dividends is dependent upon, among other things, our financial performance, our debt covenants and obligations, our ability to meet our financial obligations as they come due, our working capital requirements, our future tax obligations, our future capital requirements, commodity prices and the risk factors set forth in the documents incorporated by reference in this prospectus.

Preferred Shares

The following description is subject to, and qualified by reference to, the terms and provisions of our articles and by-laws.

Preferred shares may be issued in one or more series. The Board may determine the designation, rights, privileges, restrictions and conditions attached to each series of preferred shares before the issue of such series. Holders of preferred shares are not entitled to vote at any meeting of the shareholders of Cenovus, but may be entitled to vote if Cenovus fails to pay dividends on that series of preferred shares. The first preferred shares are entitled to priority over the second preferred shares and the common shares, and the second preferred shares are entitled to priority over the common shares, with respect to the payment of dividends and the distribution of assets of Cenovus in the event of any liquidation, dissolution or winding up of Cenovus’s affairs.

The specific terms of a series of preferred shares, including the designation of the particular series, the number of preferred shares offered, the offering price or the manner of determining the offering price, any voting rights, the dividend rate, the dividend payment dates, the terms for redemption at our option or the option of any holder, any exchange or conversion terms and any other specific terms, as described in a prospectus supplement will supplement and, if applicable, may modify or replace the general terms described in this section. Thus, the statements made in this section may not apply to a particular series of preferred shares.

DESCRIPTION OF SUBSCRIPTION RECEIPTS

This section describes the general terms that will apply to any subscription receipts that may be offered by us pursuant to this prospectus.

12

Subscription receipts may be offered separately or together with common shares and/or other Securities. The subscription receipts will be issued under one or more subscription receipt agreements that will be entered into by us and a subscription receipt agent at the time of issuance of the subscription receipts. To the extent that any terms or provisions or other information described in this prospectus differ from any of the terms or provisions or other information described in a prospectus supplement, the description set forth in this prospectus shall be deemed to have been superseded by the description set forth in the prospectus supplement with respect to those subscription receipts.

A subscription receipt will entitle the holder thereof to receive a common share and/or other Securities, for no additional consideration, upon the completion of a particular transaction or event, typically an acquisition of the assets or securities of another entity by us or one or more of our subsidiaries. The proceeds from an offering of subscription receipts will be held in escrow by an escrow agent pending the completion of the transaction or event or the termination time (the time at which the escrow terminates regardless of whether the transaction or event has occurred). Holders of subscription receipts will receive common shares and/or other Securities upon the completion of the particular transaction or event or, if the transaction or event does not occur by the termination time, a return of the subscription funds for their subscription receipts together with any interest or other income earned thereon, as determined by the terms of the applicable escrow.

Holders of subscription receipts are not shareholders of Cenovus. The particular terms and provisions of subscription receipts offered by any prospectus supplement, and the extent to which the general terms and provisions described below may apply to them, will be described in the prospectus supplement filed in respect of such subscription receipts. This description will include, where applicable: (i) the number of subscription receipts offered; (ii) the price at which the subscription receipts will be offered; (iii) the terms, conditions and procedures pursuant to which the holders of subscription receipts will become entitled to receive common shares and/or other Securities; (iv) the number of common shares and/or other Securities that may be obtained upon conversion of each subscription receipt; (v) the designation and terms of any other Securities with which the subscription receipts will be offered, if any, and the number of subscription receipts that will be offered with each such Security; (vi) the terms relating to the holding and release of the gross proceeds from the sale of the subscription receipts plus any interest and income earned thereon; (vii) the material income tax consequences of owning, holding and disposing of the subscription receipts; and (viii) any other material terms and conditions of the subscription receipts including, without limitation, transferability and adjustment terms and whether the subscription receipts will be listed on a stock exchange.

DESCRIPTION OF WARRANTS

This section describes the general terms that will apply to any warrants that may be offered by us pursuant to this prospectus.

We may issue warrants to purchase common shares, preferred shares or debt securities. Warrants may be offered separately or together with other Securities and may be attached to or separate from other Securities. The warrants will either be issued under a warrant indenture or an agreement that will be entered into between us and a trustee at the time of issuance of the warrants or will be represented by warrant certificates issued by us.

Holders of warrants are not shareholders of Cenovus. The particular terms and provisions of warrants offered by any prospectus supplement, and the extent to which the general terms and provisions described below may apply to them, will be described in the prospectus supplement filed in respect of such warrants. This description will include, where applicable: (i) the title or designation of the warrants; (ii) the number of warrants offered; (iii) the price at which the warrants will be offered; (iv) the number of common shares and/or other Securities purchasable upon exercise of the warrants and the procedures for exercise; (v) the exercise price of the warrants; (vi) the dates or periods during which the warrants are exercisable and when they expire; (vii) the designation and terms of any other Securities with which the warrants will be offered, if any, and the number of

13

warrants that will be offered with each such Security; (viii) the material income tax consequences of owning, holding and disposing of the warrants; and (ix) any other material terms and conditions of the warrants including, without limitation, transferability and adjustment terms and whether the warrants will be listed on a stock exchange. To the extent that any terms or provisions or other information described in this prospectus differ from any of the terms or provisions or other information described in a prospectus supplement, the description set forth in this prospectus shall be deemed to have been superseded by the description set forth in the prospectus supplement with respect to those warrants.

DESCRIPTION OF SHARE PURCHASE CONTRACTS

This section describes the general terms that will apply to any share purchase contracts that may be offered by us pursuant to this prospectus.

We may issue share purchase contracts, representing contracts obligating holders to purchase from or sell to us, and obligating us to purchase from or sell to the holders, a specified number of common shares or preferred shares, as applicable, at a future date or dates, and including by way of instalment.

The price per common share or preferred share and the number of common shares or preferred shares, as applicable, may be fixed at the time the share purchase contracts are issued or may be determined by reference to a specific formula or method set forth in the share purchase contracts. We may issue share purchase contracts in accordance with applicable laws and in such amounts and in as many distinct series as we may determine.

The share purchase contracts may be issued separately or as part of units. The share purchase contracts may require us to make periodic payments to the holders of the share purchase contracts or vice versa, and these payments may be unsecured or refunded and may be paid on a current or on a deferred basis. The share purchase contracts may require holders to secure their obligations under those contracts in a specified manner.

Holders of share purchase contracts are not shareholders of Cenovus. The particular terms and provisions of share purchase contracts offered by any prospectus supplement, and the extent to which the general terms and provisions described below may apply to them, will be described in the prospectus supplement filed in respect of such share purchase contracts. This description will include, where applicable: (i) whether the share purchase contracts obligate the holder to purchase or sell, or both purchase and sell, common shares or preferred shares, as applicable, and the nature and amount of each of those securities, or the method of determining those amounts; (ii) whether the share purchase contracts are to be prepaid or not or paid in instalments; (iii) any conditions upon which the purchase or sale will be contingent and the consequences if such conditions are not satisfied; (iv) whether the share purchase contracts are to be settled by delivery, or by reference or linkage to the value or performance of common shares or preferred shares; (v) any acceleration, cancellation, termination or other provisions relating to the settlement of the share purchase contracts; (vi) the date or dates on which the sale or purchase must be made, if any; (vii) whether the share purchase contracts will be issued in fully registered or global form; (viii) the material income tax consequences of owning, holding and disposing of the share purchase contracts; and (ix) any other material terms and conditions of the share purchase contracts including, without limitation, transferability and adjustment terms and whether the share purchase contracts will be listed on a stock exchange. To the extent that any terms or provisions or other information described in this prospectus differ from any of the terms or provisions or other information described in a prospectus supplement, the description set forth in this prospectus shall be deemed to have been superseded by the description set forth in the prospectus supplement with respect to those share purchase contracts.

DESCRIPTION OF UNITS

This section describes the general terms that will apply to any units that may be offered by us pursuant to this prospectus.

14

We may issue units comprised of one or more of the other Securities described in this prospectus in any combination. 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 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.

The particular terms and provisions of units offered by any prospectus supplement, and the extent to which the general terms and provisions described below may apply to them, will be described in the prospectus supplement filed in respect of such units. This description will include, where applicable: (i) 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; (ii) any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the Securities comprising the units; (iii) whether the units will be issued in fully registered or global form; and (iv) any other material terms and conditions of the units. To the extent that any terms or provisions or other information described in this prospectus differ from any of the terms or provisions or other information described in a prospectus supplement, the description set forth in this prospectus shall be deemed to have been superseded by the description set forth in the prospectus supplement with respect to those units.

RISK FACTORS

In addition to the risk factors set forth below, additional risk factors relating to our business are discussed in our Annual MD&A and our Interim MD&A, and certain other documents incorporated by reference or deemed to be incorporated by reference in this prospectus, which risk factors are incorporated by reference in this prospectus. Prospective purchasers of Securities should consider carefully the risk factors set forth below, as well as the other information contained in and incorporated by reference in this prospectus and in the applicable prospectus supplement before purchasing Securities offered hereby. If any event arising from these risks occurs, our business, prospects, financial condition, results of operations or cash flows, or your investment in the Securities could be materially adversely affected.

The common shares may be subject to price and volume fluctuations, and the market price for the common shares following an offering may drop below the offering price.

Securities markets experience considerable price and volume volatility, which may be unrelated to the operating performance of Cenovus or the affected companies. The market price of publicly traded stock is affected by many variables, including the strength of the economy generally, commodity prices, the availability and attractiveness of alternative investments and the breadth of the public market for the stock. The effect of these and other factors on the market price of securities on the stock exchanges on which we trade suggests that the trading price of the common shares may continue to be volatile. These fluctuations may affect the price of the common shares following an offering, and the market price of the common shares may drop below the offering price. As a result of this volatility, you may not be able to sell your common shares at or above the offering price.

The decision to pay dividends and the amount of such dividends is subject to the discretion of the Board based on numerous factors and may vary from time to time.

The amount of cash available to Cenovus to pay dividends, if any, can vary significantly from period to period for a number of reasons, including, among other things: Cenovus’s operational and financial performance; fluctuations in the costs to produce natural gas, bitumen, crude oil and NGLs; the amount of cash required or retained for debt service or repayment; amounts required to fund capital expenditures and working capital requirements; access to equity markets; foreign currency exchange rates and interest rates; and the risk factors set forth in this prospectus and documents incorporated by reference in this prospectus.

15

The decision whether or not to pay dividends and the amount of any such dividends are subject to the discretion of the Board, which regularly evaluates our proposed dividend payments and the solvency test requirements of the Canada Business Corporations Act. In addition, the level of dividends per common share will be affected by the number of outstanding common shares and other securities that may be entitled to receive cash dividends or other payments. Dividends may be increased, reduced or suspended from time to time. Our ability to pay dividends and the actual amount of such dividends is dependent upon, among other things, our financial performance, our debt covenants and obligations, our ability to meet our financial obligations as they come due, our working capital requirements, our future tax obligations, our future capital requirements, commodity prices and the risk factors set forth in the documents incorporated by reference in this prospectus. The market value of the common shares may deteriorate if Cenovus is unable to meet dividend expectations in the future, and that deterioration may be material.

Credit ratings accorded to Securities may not remain in effect or may change in the future and may not reflect all risks associated with an investment in the Securities.

Our perceived creditworthiness and changes in credit ratings accorded to the Securities, if any, may affect the market price or value and the liquidity of such Securities. There is no assurance that the ratings, if any, accorded to any of such Securities will remain in effect for any given period of time or that the ratings will not be revised or withdrawn entirely in the future by the relevant rating agency. Real or anticipated changes in credit ratings on such Securities may affect the market value of such Securities. In addition, real or anticipated changes in credit ratings can affect the cost of or terms on which we can issue such Securities or obtain alternative financing.

Credit ratings assigned to us and to the Securities by independent rating agencies may not reflect all risks associated with an investment in such Securities. Any credit ratings applied to such Securities are an independent assessment of our ability to pay obligations. The credit ratings, however, may not reflect the potential impact of risks related to structure, market or other factors discussed in this prospectus or documents incorporated by reference in this prospectus on the value of such Securities.

There is an absence of a public market for the debt securities, preferred shares, subscription receipts, warrants, share purchase contracts and units and there can be no assurance as to the liquidity of the trading market for such Securities or that a trading market for such Securities will develop.

Prior to an offering, there will be no public market for the debt securities, preferred shares, subscription receipts, warrants, share purchase contracts and units offered pursuant to this prospectus and we may not apply for a listing of such Securities on any securities exchange. As a result, purchasers may not be able to resell such Securities. If such Securities are traded after their initial issue, they may trade at a discount from their initial offering prices depending on prevailing interest rates, the market for similar securities and other factors, including general economic conditions and our financial condition. The absence of a public market for such Securities may affect the pricing of such Securities in the secondary market, if any such market develops, the transparency and availability of trading prices, the liquidity of such Securities and the extent of issuer regulation. There can be no assurance as to the liquidity of any trading market of such Securities or that a trading market for such Securities will develop.

In certain circumstances the debt securities may be effectively subordinated to the security interests of our lenders and the indebtedness of our subsidiaries and partnerships.

Unless otherwise provided in a prospectus supplement relating to a series of debt securities, the debt securities will be direct, unsecured and unsubordinated obligations of Cenovus, excluding its subsidiaries and partnerships, and will be effectively subordinated to all existing and future secured debt of Cenovus, to the extent of the assets securing such debt. If we are involved in any bankruptcy, dissolution, liquidation or reorganization, the holders of secured debt would be paid before the holders of debt securities receive any amounts due under the

16

debt securities to the extent of the value of the assets securing the secured debt. In that event, a holder of debt securities may not be able to recover any principal or interest due to them under the debt securities. Although our various debt instruments restrict secured indebtedness, such indebtedness may be incurred, subject to certain conditions.

In addition, our subsidiaries and partnerships may incur indebtedness, subject to certain limitations. The debt securities will be effectively subordinated to creditors of our subsidiaries and partnerships, in that our right to participate as a stockholder or partner in the distribution of the assets of any subsidiary or partnership, as the case may be, upon any such distribution would be subject to the prior claims of the creditors of such subsidiary or partnership, as the case may be. We conduct a substantial portion of our business through corporate and partnership subsidiaries.

The Indenture permits us, at any time and from time to time, to complete reorganizations with any of our wholly-owned direct or indirect subsidiaries and partnerships provided that certain conditions are met. In the event of any such reorganization, the debt securities may continue to be our obligations in circumstances where our assets are comprised of (and potentially limited to) our ownership interest in the subsidiaries through which our operations are thereafter conducted. Such subsidiaries, which following completion of a reorganization may hold all of the assets formerly held by us, are not restricted under the Indenture with respect to subsequent asset dispositions or incurring indebtedness.

Certain Securities may be subject to exchange rate and exchange controls risk.

An investment in debt securities or preferred shares that are denominated in a foreign currency may entail significant risks. Such risks include, without limitation, the possibility of significant changes in rates of exchange between the Canadian dollar and such foreign currency and the possibility of the imposition or modification of foreign controls by either the Canadian or foreign governments. Such risks generally depend on economic and political events over which we have no control. Rates of exchange between Canadian dollars and certain foreign currencies are subject to considerable volatility. Fluctuations in any particular exchange rate that have occurred in the past are not necessarily indicative of fluctuations in such rate that will occur during the term of any such Security. Depreciation of the currency in which the Security is denominated against the Canadian dollar would result in a decrease in the effective yield of such Security below its coupon rate on a Canadian dollar basis, and in certain circumstances could result in a loss to the investor on a Canadian dollar basis.

Future exchange controls may affect the availability of a specified foreign currency and our ability to make payments on Securities in a specified foreign currency.

Certain governments have imposed, and may in the future impose, exchange controls which could affect exchange rates as well as the availability of a specified foreign currency at the time of payment of principal of, and premium, if any, or interest on the Securities. Even if there are no actual exchange controls, it is possible that the specified currency for any such Security will not be available at such Security’s maturity.

In the event that any of the Securities are redeemable, purchasers of such Securities may be adversely impacted.

If any of the Securities are redeemable at our option, as set forth in the applicable prospectus supplement, we may choose to redeem such Securities from time to time, in accordance with our rights, including when prevailing interest rates are lower than the rates borne by such Securities. If prevailing rates are lower at the time of redemption, a purchaser may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the interest rate on the Securities being redeemed. Redemption rights may also adversely impact a purchaser’s ability to sell such Securities as the optional redemption date or period approaches.

17

Prevailing interest rates for comparable securities will affect the market price or value of the debt securities or preferred shares.

Prevailing interest rates will affect the market price or value of the debt securities or preferred shares. Assuming all other factors remain unchanged, the market price or value of the debt securities or preferred shares may decline as prevailing interest rates for comparable debt securities or preferred shares rise.

In the event that Securities are issued with a floating rate of interest, purchasers of such Securities may be adversely impacted.

An investment in Securities which are issued with a floating rate of interest entails significant risks not associated with investments in fixed rate Securities. The resetting of the applicable rate on a floating rate Security may result in lower interest compared to a fixed rate Security issued at the same time. The applicable rate on a floating rate Security will fluctuate in accordance with fluctuations in the instrument or obligation on which the applicable rate is based, which in turn may fluctuate and be affected by a number of interrelated factors, including economic, financial and political events over which we have no control.

CERTAIN INCOME TAX CONSIDERATIONS

The applicable prospectus supplement will describe certain Canadian federal income tax consequences to an investor of acquiring any Securities offered thereunder, including, for investors who are non-residents of Canada, whether the payments of principal, interest or distributions, if any, on the Securities will be subject to Canadian non-resident withholding tax.

The applicable prospectus supplement may also describe certain United States federal income tax consequences of the acquisition, ownership and disposition of any Securities offered thereunder by an initial investor who is a United States person (within the meaning of the United States Internal Revenue Code).

PLAN OF DISTRIBUTION

We may offer and sell Securities, and the Selling Securityholders may, including in accordance with the terms of certain registration rights agreements entered into with us, as applicable, offer and sell certain Securities to or through underwriters, brokers or dealers (including through crosses or block trades of common shares), directly to one or more purchasers or through agents. In effecting such sales, brokers or dealers may arrange for other brokers or dealers to participate. Broker-dealer transactions may include purchases of the common shares by a broker-dealer as principal and resales of the common shares by the broker-dealer for its account pursuant to this prospectus, ordinary brokerage transactions, or transactions in which the broker-dealer solicits purchasers. These Securities may be offered and sold in Canada and/or the United States and elsewhere where permitted by law.

Securities may be sold from time to time in one or more transactions at a fixed price or fixed prices, or at non-fixed prices. If offered on a non-fixed price basis, Securities may be offered at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at prices to be negotiated with purchasers, including sales in transactions that are deemed to be at-the-market distributions, including sales made directly on the TSX, the NYSE or other existing trading markets for the Securities, and as set forth in the applicable prospectus supplement. If offered on a non-fixed price basis, the price per Security may vary between purchasers and during the period of distribution. If Securities are offered on a non-fixed price basis, the underwriters’, dealers’ or agents’ compensation will be increased or decreased by the amount by which the aggregate price paid for Securities by the purchasers exceeds or is less than the gross proceeds paid by the underwriters, dealers or agents to us, or in the case of Securities offered by the Selling Securityholders, to the Selling Securityholders.

18

In connection with the sale of Securities, underwriters may receive compensation from us, and from the Selling Securityholders in the case of Securities offered by the Selling Securityholders, or from purchasers of Securities for whom they may act as agents in the form of concessions or commissions. Underwriters, dealers and agents that participate in the distribution of Securities may be deemed to be underwriters and any commissions received by them from us and/or the Selling Securityholders, as applicable and any profit on the resale of Securities by them may be deemed to be underwriting commissions under the 1933 Act.

If so indicated in the applicable prospectus supplement, we may authorize dealers or other persons acting as our agents to solicit offers by certain institutions to purchase the Securities directly from us, or in the case of Securities offered by the Selling Securityholders, the Selling Securityholders may authorize dealers or other persons acting as the Selling Securityholders’ agents to solicit offers by certain institutions to purchase such Securities directly from the Selling Securityholders, in each case, pursuant to contracts providing for payment and delivery on a future date. These contracts will be subject only to the conditions set forth in the applicable prospectus supplement or supplements, which will also set forth the commission payable for solicitation of these contracts.

The applicable prospectus supplement will also set forth the terms of the offering relating to particular Securities, including to the extent applicable, the initial offering price, our proceeds and/or those of the Selling Securityholders from the offering, the underwriting concessions or commissions, and any other discounts or concessions to be allowed or reallowed to dealers. Underwriters with respect to the particular Securities sold to or through underwriters by us and/or the Selling Securityholders, as applicable, will be named in the prospectus supplement relating to such Securities.

Subject to applicable laws, in connection with any offering of Securities, other than an at-the-market distribution, the underwriters or agents, as the case may be, may over-allot or conduct transactions intended to stabilize, maintain or otherwise affect the market price for the Securities at levels other than those which otherwise might prevail in the open market. Such transactions may be commenced, interrupted or discontinued at any time.

No underwriter or agent of an at-the-market distribution, and no person or company acting jointly or in concert with an underwriter or agent, may, in connection with the distribution, enter into any 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 the prospectus supplement applicable to the at-the-market distribution, including selling an aggregate number or principal amount of Securities that would result in the underwriter or agent, as applicable, creating an over-allocation position in the Securities.

Under agreements which may be entered into by us and/or the Selling Securityholders, underwriters, dealers and agents who participate in the distribution of Securities may be entitled to indemnification by us and/or the Selling Securityholders against certain liabilities, including liabilities under the 1933 Act and Canadian provincial and territorial securities legislation, or to contributions with respect to payments which such underwriters, dealers or agents may be required to make in respect thereof. The underwriters, dealers and agents with whom we and/or the Selling Securityholders enter into agreements may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

Any offering of debt securities, preferred shares, subscription receipts, warrants, share purchase contracts or units will be a new issue of securities with no established trading market. Unless otherwise specified in a prospectus supplement, the debt securities, preferred shares, subscription receipts, warrants, share purchase contracts or units will not be listed on any securities exchange or on any automated dealer quotation system. This may affect the pricing of the debt securities, preferred shares, subscription receipts, warrants, share purchase contracts and units in the secondary market, the transparency and availability of trading prices, the liquidity of the debt securities, preferred shares, subscription receipts, warrants, share purchase contracts and units and the extent of issuer regulation. Certain broker-dealers may make a market in the debt securities, preferred shares,

19

subscription receipts, warrants, share purchase contracts or units, but will not be obligated to do so and may discontinue any market making at any time without notice. We cannot assure you that any broker-dealer will make a market in the debt securities, preferred shares, subscription receipts, warrants, share purchase contracts or units of any series or as to the liquidity of the trading market, if any, for such securities.

The Selling Securityholders may also enter into derivative transactions with third parties. If a prospectus supplement so indicates, in connection with those derivatives, the third parties may sell certain Securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third parties may use such Securities pledged by the Selling Securityholders or borrowed from the Selling Securityholders or others to settle those sales or to close out any related open borrowings of such Securities, and may use such Securities received from the Selling Securityholders in settlement of those derivatives to close out any related open borrowings of such Securities. The third parties in such sale transactions will be underwriters and will be identified in the applicable prospectus supplement.

Certain Securities held by the Selling Securityholders and covered by this prospectus may be sold in private transactions or under Rule 144 under the 1933 Act, or under another exemption from the registration requirements of the 1933 Act, rather than pursuant to this prospectus.

EARNINGS COVERAGE

Information regarding earnings coverage ratios will be provided in the applicable prospectus supplement relating to an offering of Securities, as required by applicable securities laws.

SELLING SECURITYHOLDERS

This prospectus may also, from time to time, relate to the offering of certain Securities by way of a secondary offering by certain Selling Securityholders.

The terms under which certain Securities may be offered by the Selling Securityholders will be described in the applicable prospectus supplement. The prospectus supplement for or including any offering of such Securities by the Selling Securityholders will include, without limitation, where applicable: (a) the identity of the Selling Securityholder; (b) the number and type of Securities owned, controlled or directed by the Selling Securityholder; (c) the number and type of Securities being distributed for the account of the Selling Securityholder; and (d) the number and type of Securities to be owned, controlled or directed by the Selling Securityholder after the distribution and the percentage that number or amount represents out of the total number of outstanding Securities of the applicable type; (e) whether such Securities are owned by the Selling Securityholder, both of record and beneficially, of record only or beneficially only; (f) if a Selling Securityholder purchased any such Securities held by such Selling Securityholder within the two years preceding the date of the prospectus supplement, the date or dates such Selling Securityholder acquired such Securities; (g) if the Selling Securityholder acquired such Securities held by such Selling Securityholder within the 12 months preceding the date of the prospectus supplement, the cost thereof to the Selling Securityholder in the aggregate and on an average cost-per-security basis; (h) the disclosure required by Item 1.11 of 44-101F1 and the Selling Securityholder will file a non-issuer’s submission to jurisdiction form with the applicable prospectus supplement, if applicable; and (i) all other information that is required to be included in the applicable prospectus supplement.

LEGAL MATTERS

Unless otherwise specified in the applicable prospectus supplement, certain legal matters relating to Canadian law in connection with the offering of Securities will be passed upon for us by Blake, Cassels &

20

Graydon LLP, Calgary, Alberta and certain legal matters relating to United States law in connection with the offering of Securities will be passed upon for us by Paul, Weiss, Rifkind, Wharton & Garrison LLP, New York, New York. As of the date of this prospectus, the partners and associates of Blake, Cassels & Graydon LLP, as a group, beneficially own, directly or indirectly, less than 1% of any class of our outstanding securities.

RELIANCE ON EXEMPTIONS FOR WELL-KNOWN SEASONED ISSUERS

The securities regulatory authorities in each of the provinces and territories of Canada have adopted substantively harmonized blanket orders, including Alberta Securities Commission Blanket Order 44-501 Re Exemption from Certain Prospectus Requirements for Well-Known Seasoned Issuers (collectively with the equivalent local blanket orders in each of the other provinces and territories of Canada, the “WKSI Blanket Orders”). This prospectus has been filed by Cenovus in reliance upon the WKSI Blanket Orders, which permit “well-known seasoned issuers”, or “WKSIs”, to file a final short form base shelf prospectus as the first public step in an offering, and exempt qualifying issuers from certain disclosure requirements relating to such final short form base shelf prospectus. As of the date hereof, Cenovus has determined that it qualifies as a “well-known seasoned issuer” under the WKSI Blanket Orders.

DOCUMENTS FILED AS PART OF THE REGISTRATION STATEMENT

The following documents have been or will be filed with the SEC as part of the registration statement of which this prospectus is a part insofar as required by the SEC’s Form F-10:

PART II

INFORMATION NOT REQUIRED TO BE DELIVERED

TO OFFEREES OR PURCHASERS

Indemnification of Directors and Officers

Under Section 124 of the Canada Business Corporations Act (the “CBCA”), Cenovus Energy Inc. (“Cenovus”) may indemnify a present or former director or officer of Cenovus or another individual who acts or acted at Cenovus’s request as a director or officer, or an individual acting in a similar capacity, of another entity, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual is involved because of that association with Cenovus or other entity. Cenovus may not indemnify such an individual unless the individual acted honestly and in good faith with a view to the best interests of Cenovus, or, as the case may be, to the best interests of the other entity for which the individual acted as a director or officer or in a similar capacity at Cenovus’s request and in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, the individual had reasonable grounds for believing that the individual’s conduct was lawful. The indemnification may be made in connection with a derivative action only with court approval. The aforementioned individuals are entitled to indemnification from Cenovus as a matter of right if they were not judged by the court or other competent authority to have committed any fault or omitted to do anything that the individual ought to have done. Cenovus may advance moneys to a director, officer or other individual for the costs, charges and expenses of an aforementioned proceeding; however, the individual shall repay the moneys if the individual does not fulfill the conditions set out above.

The by-laws of Cenovus provide that, subject to the limitations contained in the CBCA, but without limit to the right of Cenovus to indemnify any person under the CBCA or otherwise, Cenovus shall indemnify a director or officer of Cenovus, a former director or officer of Cenovus or another individual who acts or acted at Cenovus’s request as a director or officer, or an individual acting in a similar capacity, of another entity, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual is involved because of that association with Cenovus or other entity, if the individual acted honestly and in good faith with a view to the best interests of Cenovus, or, as the case may be, to the best interests of the other entity for which the individual acted as director or officer or in a similar capacity at Cenovus’s request, and in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, the individual had reasonable grounds for believing that the individual’s conduct was lawful.

The by-laws of Cenovus provide that Cenovus may, subject to the limitations contained in the CBCA, purchase, maintain, or participate in insurance for the benefit of a director or officer of Cenovus, a former director or officer of Cenovus, or another individual who acts or acted at Cenovus’s request as a director or officer, or an individual acting in a similar capacity, of another entity, as the Board may from time to time determine.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling Cenovus pursuant to the foregoing provisions, Cenovus has been informed that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.
