PROSPECTUS SUMMARY

Before investing in Securities, you should carefully read this entire Prospectus, the applicable Prospectus Supplement and any related free writing prospectus, including our financial statements and the related notes and other documents incorporated by reference in this Prospectus, as well as the risks of investing in our Securities discussed under the heading “Risk Factors” contained in the applicable Prospectus Supplement and any related free writing prospectus and under similar headings in the other documents that are incorporated by reference into this Prospectus and the applicable Prospectus Supplement.

Our Company

enCore Energy Corp., America’s Clean Energy Company^™, was incorporated on October 30, 2009, under the laws of British Columbia and is a reporting issuer in all of the provinces and territories of Canada. As of January 1, 2025, the Company ceased to be a “foreign private issuer” and has become a “domestic issuer” and a non-accelerated filer within the meanings under the Securities Exchange Act of 1934 (the “Exchange Act”). As a result, the Company must comply with the filing deadlines and disclosure obligations of a domestic issuer and non-accelerated filer as set forth in the Exchange Act. This classification impacts the timing of our periodic filings, internal control assessments, and other regulatory requirements. The Company’s Common Shares are listed on Nasdaq and the TSX-V under the trading symbol EU.

As of March 31, 2026, the Company is an “Exploration Stage Issuer” as defined by Regulation S-K 1300 (“S-K 1300”) of the Securities Act of 1933, as amended (the “Securities Act”), as it has not established proven or probable mineral reserves through the completion of a pre-feasibility or feasibility study for any of our uranium projects, as required by the SEC to be defined as a “Development Stage Issuer”. Even though we commenced extraction of uranium at our Rosita Uranium Project and our Alta Mesa Uranium Project, the Company remains classified as an Exploration Stage Issuer and will continue to remain an Exploration Stage Issuer until such time as proven or probable mineral reserves have been established at one of our uranium projects.

The Company is focused on extracting domestic uranium within the United States. The Company only utilizes proven in-situ recovery (“ISR”) technology to provide necessary fuel for the generation of clean, reliable, and carbon-free nuclear energy. In 2023, the Company commenced uranium extraction at the Rosita central processing plant (“CPP”) and at the Alta Mesa CPP in South Texas. enCore’s strategy is to build uranium extraction capacity by developing and placing into operation a series of uranium extraction facilities in South Texas, followed by a future pipeline of exploration projects in South Dakota and Wyoming, becoming a leading supplier of domestic uranium to fuel a growing demand for clean energy generation using nuclear power.

Corporate Organization

enCore was incorporated on October 30, 2009 under the Business Corporations Act (British Columbia) (the “BCBCA”) under the name “Dauntless Capital Corp.” The Company’s name was changed to “Tigris Uranium Corp.” on September 2, 2010, and changed to “Wolfpack Gold Corp.” on May 15, 2013. On August 15, 2014, the Company’s name was changed to “enCore Energy Corp.”

The Company’s principal executive offices are located at One Galleria Tower, 13355 Noel Rd, Suite 1700 Dallas, Texas 75240. The Company’s telephone number is (361) 239-2025. The Company maintains a website located at www.encoreuranium.com. From time to time, we may use our website as a distribution channel for material company information.

Each of the risks described in these documents could materially and adversely affect our business, financial condition, results of operations and prospects, and could result in a partial or complete loss of your investment. See “Where You Can Find More Information” and “Documents Incorporated by Reference.”

USE OF PROCEEDS

Except as otherwise may be described in an applicable Prospectus Supplement, we intend to use the net proceeds from the sale of the securities offered hereunder for general corporate purposes, including, among other possible uses, mergers and acquisitions, the repayment or refinancing of short-term or long-term debt or lease obligations and other capital expenditures.

DESCRIPTION OF COMMON SHARES

The authorized capital of the Company consists of an unlimited number of Common Shares without par value and an unlimited number of Preferred Shares without par value. As of March 31, 2026, there were 194,216,153 Common Shares issued and outstanding and no Preferred Shares are issued and outstanding. Additionally, as of March 31, 2026 there were (i) options outstanding to purchase up to 6,610,641 Common Shares at exercise prices ranging from CAD$2.40 to CAD$5.76 and $3.10 to $3.47, (ii) 3,958,425 restricted stock units outstanding and (iii) 34,959,724 Common Shares issuable upon conversion of the Company’s 5.50% Senior Convertible Notes due 2030, assuming conversion in full on such date at the initial conversion rate of 303.9976 Common Shares per $1,000 principal amount of notes.

The Common Shares are subject to the following rights, privileges, restrictions and conditions:

the holders of the Common Shares are entitled to receive notice of, and attend at, and to vote in person or by proxy at general meetings of enCore shareholders and will be entitled to one vote for each such Common Share held;

subject to the rights of the Preferred Shares as determined by the directors and in accordance with the Articles, the directors may, in their discretion, at any time and from time to time declare and cause enCore to pay dividends on the Common Shares; and

subject to the rights, privileges, restrictions and conditions attaching to the Preferred Shares, in the event of liquidation or dissolution of enCore or other distribution of assets of enCore among its shareholders for the purpose of winding up its affairs, whether voluntary or involuntary, the holders of the Common Shares will be entitled to share equally, share for share, in the distribution of the remaining property and assets of enCore.

The rights and restrictions attached to the Common Shares may be altered by resolutions of the Board, subject to the provisions of the BCBCA.

The transfer agent and registrar for the Common Shares is Computershare Trust Company of Canada at its principal office in Vancouver, British Columbia located at 510 Burrard Street, 3rd Floor, Vancouver, British Columbia, V6C 3B9.

DESCRIPTION OF PREFERRED SHARES

The authorized capital of the Company consists of an unlimited number of Preferred Shares without par value. As at the date of this Prospectus, there are no Preferred Shares issued and outstanding. The Preferred Shares issuable in series will have the rights, privileges, restrictions and conditions assigned to the particular series upon the Board approving their issuance, subject to the Articles. Accordingly, our Board, without shareholder approval, may issue Preferred Shares with voting, conversion or other rights that could adversely affect the voting power and other rights of the holders of our Common Shares. Preferred Shares could be issued quickly with terms calculated to delay or prevent a change of control or make removal of management more difficult. Additionally, the issuance of Preferred

Shares may have the effect of decreasing the market price of our Common Shares, may adversely affect the voting and other rights of the holders of our Common Shares, and could have the effect of delaying, deferring or preventing a change of control of our Company or other corporate action. Preferred Shares offered hereby, upon issuance against full payment of the purchase price therefor, will be fully paid and nonassessable.

The Prospectus Supplement relating to a particular class or series of Preferred Shares offered will describe the specific terms thereof, including, where applicable:

•

the title, designation, number of shares and stated value of the Preferred Shares;

•

the price at which the Preferred Shares will be issued;

•

the dividend rates, if any (or method of calculation), whether that rate is fixed or variable or both, and the dates on which dividends will be payable, whether those dividends will be cumulative or noncumulative and, if cumulative, the dates from which dividends will begin to accumulate;

•

the dates on which the Preferred Shares will be subject to redemption and the applicable redemption prices;

•

any redemption or sinking fund provisions;

•

the convertibility or exchangeability of the Preferred Shares;

•

if other than United States dollars, the currency or currencies (including composite currencies) in which the Preferred Shares are denominated and/or in which payments will or may be payable;

•

the method by which amounts in respect of the Preferred Shares may be calculated and any commodities, currencies or indices, or the value, rate or price relevant to that calculation;

•

the place where dividends and other payments on the Preferred Shares are payable and the identity of the transfer agent, registrar and dividend disbursement agent for the Preferred Shares;

•

any listing of the Preferred Shares on any securities exchange; and

•

any additional dividend, liquidation, redemption, preemption, sinking fund, voting and other rights, preferences, privileges, limitations and restrictions.

The federal income tax consequences and special considerations applicable to any class or series of Preferred Shares will be generally described in the Prospectus Supplement related thereto.

Each series of Debt Securities may be issued at various times with different maturity dates, may bear interest at different rates and may otherwise vary.

If we denominate the purchase price of any of the Debt Securities in a currency or currencies (or a currency unit or units) other than the currency of the United States, or if the principal of and any premium and interest on any series of Debt Securities is payable in a currency or currencies (or a currency unit or units) other than the currency of the United States, we will provide you with information on the restrictions, elections, general tax considerations, specific terms and other information with respect to that issue of Debt Securities and such foreign currency or currencies or foreign currency unit or units in the applicable Prospectus Supplement.

The terms on which a series of Debt Securities may be convertible into or exchangeable for Common Shares or other Securities will be summarized in the applicable Prospectus Supplement. These terms may include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option, and may include provisions pursuant to which the number of Common Shares or other Securities to be received by the holders of such series of Debt Securities would be subject to adjustment.

To the extent any Debt Securities are convertible into Common Shares or other Securities, prior to such conversion the holders of such Debt Securities will not have any of the rights of holders of the Securities into which the Debt Securities are convertible, including the right to receive payments of dividends or the right to vote such underlying securities.

We will set forth in the applicable Prospectus Supplement any restrictive covenants applicable to any issue of Debt Securities.

We expect the Indenture, the Debt Securities and any guarantees will be governed by, and construed in accordance with, the laws of the state of New York, and if there is any change to the governing law, we will disclose such governing law in the applicable Prospectus Supplement.

Prior to the exercise of any Warrants, holders of such Warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including the right to receive payments of dividends or the right to vote such underlying securities.

DESCRIPTION OF SUBSCRIPTION RECEIPTS

The following description sets forth certain general terms and provisions of Subscription Receipts that may be issued hereunder and is not intended to be complete. Subscription Receipts may be issued at various times which will entitle holders thereof to receive, upon satisfaction of certain release conditions and for no additional consideration, Common Shares, Preferred Shares, Warrants, Units or any combination thereof. The Subscription Receipts may be offered separately or together with other Securities, as the case may be. Subscription Receipts will be issued pursuant to one or more subscription receipt agreements (each, a “Subscription Receipt Agreement”), each to be entered into between the Company and an escrow agent (the “Escrow Agent”) that will be named in the relevant Prospectus Supplement. Each Escrow Agent will be a financial institution organized under the laws of Canada or a province thereof and authorized to carry on business as a trustee. The subscription proceeds from an offering of Subscription Receipts will be held in escrow by the Escrow Agent pending the completion of the transaction or the termination time (the time at which the escrow terminates regardless of whether the transaction or event has occurred). If underwriters, dealers or agents are used in the sale of any Subscription Receipts, one or more of such underwriters, dealers or agents may also be a party to the Subscription Receipt Agreement governing the Subscription Receipts sold to or through such underwriter, dealer or agent.

The statements made in this Prospectus relating to any Subscription Receipt Agreement and Subscription Receipts to be issued under this Prospectus are summaries of certain anticipated provisions thereof and do not purport to be complete and are subject to, and are qualified in their entirety by reference to, the provisions of the applicable Subscription Receipt Agreement. Purchasers of Subscription Receipts should refer to the Subscription Receipt Agreement relating to the specific Subscription Receipts being offered for the complete terms of the Subscription Receipts. A copy of any Subscription Receipt Agreement relating to an offering of Subscription Receipts will be filed by the Company with the securities regulatory authorities in the applicable Canadian offering jurisdictions and with the SEC after the Company has entered into it.

The particular terms of each issue of Subscription Receipts will be described in the related Prospectus Supplement. This description may include, but is not limited to, any of the following, if applicable:

•

the designation and aggregate number of the Subscription Receipts being offered;

•

the price at which the Subscription Receipts will be offered;

•

the designation, number and terms of the Common Shares, Preferred Shares, Warrants, Units or any combination thereof to be received by the holders of the Subscription Receipts upon satisfaction of the release conditions, and any procedures that will result in the adjustment of those numbers;

•

procedures for the refund by the Escrow Agent to holders of the Subscription Receipts of all or a portion of the subscription price of their Subscription Receipts, plus any pro rata entitlement to interest earned or income generated on such amount, if the Release Conditions are not satisfied;

•

any contractual right of rescission to be granted to initial purchasers of the Subscription Receipts in the event that this Prospectus, the Prospectus Supplement under which Subscription Receipts are issued or any amendment hereto or thereto contains a misrepresentation;

•

any entitlement of the Company to purchase the Subscription Receipts in the open market by private agreement or otherwise;

•

whether the Company will issue the Subscription Receipts as bearer securities, as registered securities or both;

•

provisions as to modification, amendment or variation of the Subscription Receipt Agreement or any rights or terms of the Subscription Receipts, including upon any subdivision, consolidation, reclassification or other material change of the Common Shares, Preferred Shares, Warrants or Units, any other reorganization, amalgamation, merger or sale of all or substantially all of the Company’s assets or any distribution of property or rights to all or substantially all of the holders of Common Shares;

•

whether the Company will apply to list the Subscription Receipts on any securities exchange;

•

the material United States and Canadian federal income tax consequences of owning the Subscription Receipts; and

•

any other material terms and conditions of the Subscription Receipts.

Rights of Holders of Subscription Receipts Prior to Satisfaction of Release Conditions

The holders of Subscription Receipts will not be, and will not have the rights of, shareholders of the Company. Holders of Subscription Receipts are entitled only to receive Common Shares, Preferred Shares, Warrants, Units or a combination thereof on exchange or conversion of their Subscription Receipts, plus any cash payments, all as provided for under the Subscription Receipt Agreement and only once the Release Conditions have been satisfied.

Escrow

The Subscription Receipt Agreement will provide that the Escrowed Funds will be held in escrow by the Escrow Agent, and such Escrowed Funds will be released to the Company (and, if the Subscription Receipts are sold to or through underwriters, dealers or agents, a portion of the Escrowed Funds may be released to such underwriters, dealers or agents in payment of all or a portion of their fees in connection with the sale of the Subscription Receipts) at the time and under the terms specified by the Subscription Receipt Agreement. If the Release Conditions are not satisfied, holders of Subscription Receipts will receive a refund of all or a portion of the subscription price for their Subscription Receipts, plus their pro-rata entitlement to interest earned or income generated on such amount, if provided for in the Subscription Receipt Agreement, in accordance with the terms of the Subscription Receipt Agreement.

Modifications

The Subscription Receipt Agreement will specify the terms upon which modifications and alterations to the Subscription Receipts issued thereunder may be made by way of a resolution of holders of Subscription Receipts at a meeting of such holders or consent in writing from such holders. The number of votes of holders of Subscription Receipts required to pass such a resolution or execute such a written consent will be specified in the Subscription Receipt Agreement. The Subscription Receipt Agreement will also specify that the Company may amend the Subscription Receipt Agreement and the Subscription Receipts, without the consent of the holders of the Subscription Receipts, to cure any ambiguity, to cure, correct or supplement any defective or inconsistent provision, or in any other manner that will not materially and adversely affect the interests of the holders of outstanding Subscription Receipts or as otherwise specified in the Subscription Receipt Agreement.

DESCRIPTION OF SHARE PURCHASE CONTRACTS

We may issue Share Purchase Contracts, including contracts obligating holders to purchase from us, and obligating us to sell to holders, a fixed or varying number of Common Shares or Preferred Shares at a future date or dates. The consideration per Common Share or Preferred Share may be fixed at the time that Share Purchase Contracts are issued or may be determined by reference to a specific formula set forth in the Share Purchase Contracts. Any Share Purchase Contract may include anti-dilution provisions to adjust the number of shares issuable pursuant to such Share Purchase Contract upon the occurrence of certain events.

The Share Purchase Contracts may be issued separately or as a part of units, often known as Share Purchase Units, consisting of a Share Purchase Contract and any combination of Debt Securities or debt obligations of third parties, including U.S. Treasury securities, securing the holder’s obligations to purchase the Common Shares or Preferred Shares under the Share Purchase Contracts. The Share Purchase Contracts may require us to make periodic payments to holders of the Share Purchase Units, or vice versa, and such payments may be unsecured or prefunded and may be paid on a current or on a deferred basis.

Any one or more of the above Securities, Common Shares or the Share Purchase Contracts or other collateral may be pledged as security for the holders’ obligations to purchase or sell, as the case may be, the Common Shares or Preferred Shares under the Share Purchase Contracts. The specific terms and provisions that will apply to any Share Purchase Contract or Share Purchase Units that may be offered by us pursuant to this Prospectus will be set forth in the applicable Prospectus Supplements.

DESCRIPTION OF UNITS

As of the date of this Prospectus, the Company has no Units outstanding. Each Unit would be issued so that the holder of the Unit is also the holder of each Security comprising the Unit. Thus, the holder of a Unit will have the

rights and obligations of a holder of each applicable Security. The specific terms and provisions that will apply to any Units that may be offered by us pursuant to this Prospectus will be set forth in the applicable Prospectus Supplement. This description will include, where applicable:

•

the number of Units offered;

•

the price or prices, if any, at which the Units will be issued;

•

the manner of determining the offering price(s);

•

the currency at which the Units will be offered;

•

the Securities comprising the Units;

•

whether the Units will be issued with any other Securities and, if so, the amount and terms of these Securities;

•

if a Share Purchase Unit, the Debt Securities and/or debt obligations of third parties securing the Share Purchase Contract;

•

any minimum or maximum subscription amount;

•

whether the Units and Securities comprising the Units are to be issued in registered form, “book-entry only” form, non-certificated inventory system form, bearer form or in the form of temporary or permanent global securities and the basis of exchange, transfer and ownership thereof;

•

any material risk factors relating to such Units or the Securities comprising the Units;

•

any other rights, privileges, restrictions and conditions attaching to the Units or the Securities comprising the Units; and

•

any other material terms or conditions of the Units or the Securities comprising the Units, including whether and under what circumstances the Securities comprising the Units may be held or transferred separately.

The terms and provisions of any Units offered under a Prospectus Supplement may differ from the terms described above, and may not be subject to or contain any or all of the terms described above.

PLAN OF DISTRIBUTION

We may sell the Securities offered by this Prospectus in any one or more of the following ways from time to time:

•

directly to investors, including through a specific bidding, auction or other process;

•

to investors through agents;

•

directly to agents;

•

to or through brokers or dealers;

•

to the public through underwriting syndicates led by one or more managing underwriters;

•

to one or more underwriters acting alone for resale to investors or to the public;

•

through a combination of any such methods of sale; or

•

any other method permitted pursuant to applicable law.

We may also sell the Securities offered by this Prospectus in “at the market offerings” within the meaning of Rule 415(a)(4) under the Securities Act of 1933, as amended (the “Securities Act”), to or through a market maker or into an existing trading market, on an exchange or otherwise. Unless provided otherwise in any applicable Prospectus Supplement, the Company intends to cap the use of any “at the market offering” to $250 million gross proceeds.

The accompanying Prospectus Supplement will set forth the terms of the offering and the method of distribution and will identify any firms acting as underwriters, dealers or agents in connection with the offering, including:

•

the names or names of any underwriters, dealers or agents;

•

the purchase price of the Securities and the proceeds to us from the sale;

•

any over-allotment options under which the underwriters may purchase additional Securities from us;

•

any underwriting discounts and other items constituting compensation to underwriters, dealers or agents;

•

any public offering price;

•

any discounts or concessions allowed or reallowed or paid to dealers; or

•

any securities exchange or market on which the Securities offered in the Prospectus Supplement may be listed.

Only those underwriters identified in such Prospectus Supplement are deemed to be underwriters in connection with the Securities offered in the Prospectus Supplement. Any underwritten offering may be on a best efforts or a firm commitment basis.

The distribution of the Securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, at varying prices determined at the time of sale, or at prices determined as the applicable Prospectus Supplement specifies. The Securities may be sold through a rights offering, forward contracts or similar arrangements.

In connection with the sale of the Securities, underwriters, dealers or agents may be deemed to have received compensation from us in the form of underwriting discounts or commissions and also may receive commissions from securities purchasers for whom they may act as agent. Underwriters may sell the Securities to or through dealers, and the dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or commissions from the purchasers for whom they may act as agent.

We will provide in the applicable Prospectus Supplement information regarding any underwriting discounts or other compensation paid to underwriters or agents in connection with the Securities offering, and any discounts, concessions or commissions which underwriters allow to dealers. Underwriters, dealers and agents participating in the Securities distribution may be deemed to be underwriters, and any discounts and commissions they receive and any profit they realize on the resale of the Securities may be deemed to be underwriting discounts and commissions under the Securities Act. Underwriters and their controlling persons, dealers and agents may be entitled, under agreements entered into with us, to indemnification against and contribution toward specific civil liabilities, including liabilities under the Securities Act.

Any Common Shares sold pursuant to a Prospectus Supplement will be listed on Nasdaq, subject to official notice of issuance. We may elect to list any series of Preferred Shares on an exchange, but we are not obligated to do so. It is possible that one or more underwriters may make a market in the Securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given as to the liquidity of, or the trading market for, any offered Securities.

In connection with an offering, the underwriters may purchase and sell Securities in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of Securities than they are required to purchase in an offering. Stabilizing transactions consist of bids or purchases made for the purpose of preventing a decline in the market price of the Securities while an offering is in progress. The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the underwriters have repurchased Securities sold by or for the account of that underwriter in stabilizing or short-covering transactions. These activities by the underwriters may stabilize, maintain or otherwise affect the market price of the Securities. As a result, the price of the Securities may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. Underwriters may engage in over-allotment. If any underwriters create a short position in the securities in an offering in which they sell more Securities than are set forth on the cover page of the applicable Prospectus Supplement, the underwriters may reduce that short position by purchasing the Securities in the open market.

Underwriters, dealers or agents that participate in the offer of Securities, or their affiliates or associates, may have engaged or engage in transactions with and perform services for, us or our affiliates in the ordinary course of business for which they may have received or receive customary fees and reimbursement of expenses.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS FOR NON-RESIDENTS OF CANADA

The following portion of this summary is generally applicable to a holder who acquires, as beneficial owner, our Common Shares, and who, for purposes of the Income Tax Act (Canada) and the regulations promulgated thereunder (the “Tax Act”) and at all relevant times, is neither resident nor deemed to be resident in Canada and does not use or hold, and will not be deemed to use or hold, Common Shares in a business carried on in Canada (each, a “Non-Resident Holder”). The term “American Holder,” for the purposes of this summary, means a Non-Resident Holder who, for purposes of the Canada-U.S. Tax Convention, is at all relevant times a resident of the United States and is a “qualifying person” within the meaning of the Canada-U.S. Tax Convention eligible for the full benefits of the Canada-U.S. Tax Convention. In some circumstances, persons deriving amounts through fiscally transparent entities (including limited liability companies) may be entitled to benefits under the Canada-U.S. Tax Convention. American Holders are urged to consult their own tax advisors to determine their entitlement to benefits under the Canada-U.S. Tax Convention and related compliance requirements based on their particular circumstances.

Special considerations, which are not discussed in this summary, may apply to a Non-Resident Holder that is an insurer that carries on an insurance business in Canada and elsewhere or an authorized foreign bank (as defined in the Tax Act). Such Non-Resident Holders should consult their own advisors.

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

Non-Resident Holders should consult their own tax advisors with respect to an investment in our Common Shares. This summary is of a general nature only and is not intended to be, nor should it be construed to be, legal or tax advice to any prospective purchaser or holder of our Common Shares, and no representations with respect to the income tax consequences to any prospective purchaser or holder are made. Consequently, prospective purchasers or holders of our Common Shares should consult their own tax advisors with respect to their particular circumstances.

Currency Conversion

Generally, for purposes of the Tax Act, all amounts relating to the acquisition, holding, or disposition of our Common Shares, including dividends, adjusted cost base and proceeds of disposition, must be converted into Canadian Dollars based on the exchange rates as determined in accordance with the Tax Act. The amounts subject to withholding tax and any capital gains or capital losses realized by a Non-Resident Holder may be affected by fluctuations in the value of the Canadian Dollar relative to other currencies.

Taxation of Dividends

Subject to an applicable tax treaty or convention, dividends paid or credited, or deemed to be paid or credited, to a Non-Resident Holder on the Common Shares will be subject to Canadian withholding tax under the Tax Act at the rate of 25% of the gross amount of the dividend. Such rate is generally reduced under the Canada-U.S. Tax Convention to 15% if the beneficial owner of such dividend is an American Holder. The rate of withholding tax is generally further reduced to 5% if the beneficial owner of such dividend is an American Holder that is a company that owns at least 10% of the voting shares of the Company. Non-Resident Holders should consult their own tax advisors to determine their entitlement to benefits under any applicable tax treaty or convention based on their particular circumstances.

Disposition of Common Shares

A Non-Resident Holder will not be subject to tax under the Tax Act in respect of any capital gain realized by such Non-Resident Holder on a disposition of Common Shares, unless the Common Shares constitute “taxable Canadian property” (as defined in the Tax Act) of the Non-Resident Holder at the time of the disposition and are not “treaty-protected property” (as defined in the Tax Act) of the Non-Resident Holder at the time of the disposition.

Generally, provided the Common Shares are listed on a “designated stock exchange” as defined in the Tax Act (which currently includes the TSX-V and Nasdaq) at the time of disposition, the Common Shares will not

constitute taxable Canadian property of a Non-Resident Holder, unless at any time during the 60-month period immediately preceding the disposition the following two conditions are met concurrently: (a) the Non-Resident Holder, persons with which the Non-Resident Holder does not deal at arm’s length, partnerships whose members include, either directly or indirectly through one or more partnerships, the Non-Resident Holder and/or persons which do not deal at arm’s length with the Non-Resident Holder, or any combination of the foregoing, owned 25% or more of the issued shares of any class or series of shares of the capital stock of the Company, and (b) more than 50% of the fair market value of the Common Shares was derived directly or indirectly, from one or any combination of real or immovable property situated in Canada, “Canadian resource properties,” “timber resource properties” (each as defined in the Tax Act), and options in respect of or interests in, or for civil law rights in, any such property (whether or not such property exists). Notwithstanding the foregoing, Common Shares may also be deemed to be “taxable Canadian property” of a Non-Resident Holder in other circumstances under the Tax Act.

The Common Shares of an American Holder will generally constitute “treaty-protected property” for purposes of the Tax Act unless the value of the Common Shares is derived principally from real property situated in Canada. For this purpose, “real property” has the meaning that term has under the laws of Canada and includes any option or similar right in respect thereof and in any case, includes usufruct of real property, rights to explore for or to exploit mineral deposits, sources and other natural resources and rights to amounts computed by reference to the amount or value of production from such resources.

If Common Shares are taxable Canadian property of a Non-Resident Holder and are not treaty-protected property of the Non-Resident Holder at the time of their disposition, the Non-Resident Holder may owe Canadian income tax on any taxable capital gains realized and should consult their own tax advisor with respect to the procedures that must be followed when disposing of taxable Canadian property.

Non-Resident Holders whose Common Shares may constitute taxable Canadian property should consult their own advisors.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following is a general summary of certain U.S. federal income tax considerations applicable to a U.S. Holder (as defined below) arising from the ownership and disposition of Common Shares. This summary is for general information purposes only and does not purport to be a complete analysis or listing of all potential U.S. federal income tax considerations that may apply to a U.S. Holder. In addition, this summary does not take into account the individual facts and circumstances of any particular U.S. Holder that may affect the U.S. federal income tax consequences to such holder (as discussed below), including specific tax consequences to a holder under an applicable tax treaty. Accordingly, this summary is not intended to be, and should not be construed as, legal or U.S. federal income tax advice with respect to any holder. This summary is limited to U.S. federal income tax considerations, and does not address the U.S. federal alternative minimum, net investment income, U.S. federal estate and gift, U.S. state and local, or non-U.S. tax consequences of the ownership and disposition of such Common Shares. Except as specifically set forth below, this summary does not discuss applicable income tax reporting requirements. Each holder should consult its own tax advisor regarding all U.S. federal, U.S. state and local, and non-U.S. tax consequences of the ownership and disposition of Common Shares.

No opinion from U.S. legal counsel or ruling from the U.S. Internal Revenue Service (“IRS”) has been requested, or will be obtained, regarding the U.S. federal income tax consequences of the ownership and disposition of Common Shares. This summary is not binding on the IRS, and the IRS is not precluded from taking a position that is different from, and contrary to, the positions taken in this summary. In addition, because the authorities on which this summary is based are subject to various interpretations, the IRS and the U.S. courts could disagree with one or more of the positions taken in this summary.

This summary does not address the U.S. federal income tax consequences to any particular person of the ownership and disposition of Common Shares. Each holder should consult its own tax advisor regarding all U.S. federal, U.S. state and local, and non-U.S. tax consequences of the ownership and disposition of Common Shares.

Scope of This Disclosure

Authorities

This summary is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), proposed, final and temporary U.S. Treasury Regulations, published rulings of the IRS, published administrative positions of the IRS, and U.S. court decisions that are applicable and, in each case, as in effect and available, as of the date of this Prospectus. Any of the authorities on which this summary is based could be changed in a material and adverse manner at any time, and any such change could be applied on a prospective or retroactive basis which could affect the U.S. federal income tax considerations described in this summary. This summary does not discuss the potential effects, whether adverse or beneficial, of any proposed legislation that, if enacted, could be applied on a retroactive or prospective basis.

U.S. Holders

For purposes of this summary, the term “U.S. Holder” means a beneficial owner of Common Shares that is for U.S. federal income tax purposes:

•

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

•

a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

•

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

•

a trust that (a) is subject to the primary supervision of a court within the United States and the control of one or more U.S. persons for all substantial decisions or (b) has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a U.S. person.

Non-U.S. Holders

Also, for purposes of this discussion, a “Non-U.S. Holder” is any beneficial owner of Common Shares who is neither a U.S. Holder nor an entity classified as a partnership for U.S. federal income tax purposes. This summary does not address the U.S. federal income tax considerations applicable to Non-U.S. Holders relating to the acquisition, ownership and disposition of Common Shares. Accordingly, Non-U.S. Holders should consult their own tax advisors regarding the U.S. federal, U.S. state and local, and non-U.S. tax consequences (including the potential application of and operation of any tax treaties) relating to the acquisition, ownership, and disposition of Common Shares.

This summary does not address the U.S. federal income tax consequences of the ownership and disposition of Common Shares that are subject to special provisions under the Code, including holders that: (a) are tax-exempt organizations, qualified retirement plans, individual retirement accounts, or other tax-deferred accounts; (b) are financial institutions, underwriters, insurance companies, real estate investment trusts, or regulated investment companies; (c) are broker-dealers, dealers, or traders in securities or currencies that elect to apply a mark-to-market accounting method; (d) have a “functional currency” other than the U.S. dollar; (e) own Common Shares as part of a straddle, hedging transaction, conversion transaction, constructive sale, or other arrangement involving more than one position; (f) acquired Common Shares in connection with the exercise of

employee stock options or otherwise as compensation for services; (g) hold Common Shares other than as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment purposes); (h) own, directly, indirectly, or by attribution, 5% or more, by voting power or value, of the outstanding Common Shares; (i) are required to accelerate the recognition of any item of gross income for U.S. federal income tax purposes with respect to Common Shares as a result of such item being taken into account in an applicable financial statement; (j) acquired Common Shares by gift or inheritance; (k) are certain former citizens or long-term residents of the United States; (l) are pension plans; (m) are integral parts or controlled entities of foreign sovereigns; or (n) are passive foreign investment companies and corporations that accumulate earnings to avoid U.S. federal income tax. Holders that are subject to special provisions under the Code, including those holders described immediately above, should consult their own tax advisors regarding all U.S. federal, U.S. state and local, and non-U.S. tax consequences relating to the ownership and disposition of Common Shares.

If an entity or arrangement that is classified as a partnership (including any other “pass-through” entity) for U.S. federal income tax purposes holds Common Shares, the U.S. federal income tax consequences to such partnership and the partners (or owners) of such partnership of participating in the ownership and disposition of Common Shares generally will depend on the activities of the partnership and the status of such partners (or owners). This summary does not address the tax consequences to any such partnership or partner (or owner). Partners (or owners) of entities and arrangements that are classified as partnerships for U.S. federal, U.S. state and local, and non-tax purposes should consult their own tax advisors regarding the U.S. federal income tax consequences of the ownership and disposition of Common Shares.

U.S. Tax Considerations Relevant to the Ownership and Disposition of Common Shares

Distributions

We do not currently anticipate paying distributions on our Common Shares. Subject to the PFIC rules discussed below, a U.S. Holder that receives a distribution, including a constructive distribution, with respect to Common Shares will be required to include the amount of such distribution in gross income as a dividend (without reduction for any Canadian income tax withheld from such distribution) to the extent of the current or accumulated “earnings and profits” of the Company, as computed for U.S. federal income tax purposes. To the extent that a distribution exceeds the current and accumulated “earnings and profits” of the Company, such distribution will be treated first as a tax-free return of capital to the extent of a U.S. Holder’s tax basis in the Common Shares and thereafter as a gain from the sale or exchange of such Common Shares (see “Sale, Exchange or Other Taxable Disposition of Common Shares” below). However, the Company does not intend to maintain the calculations of earnings and profits in accordance with U.S. federal income tax principles, and each U.S. Holder should therefore assume that any distribution by the Company with respect to the Common Shares will constitute ordinary dividend income. Subject to applicable limitations, dividends paid by the Company to non-corporate U.S. Holders, including individuals, generally will be eligible for the preferential tax rates applicable to long-term capital gains for dividends, provided certain holding period and other conditions are satisfied, including that the Company not be classified as a PFIC (as discussed below) in the tax year of distribution or in the preceding tax year. Dividends received on Common Shares by corporate U.S. Holders will not be eligible for the “dividends received deduction.” The dividend rules are complex, and each U.S. Holder should consult its own tax advisor regarding the application of such rules.

Sale, Exchange or Other Taxable Disposition of Common Shares

Subject to the PFIC rules discussed below, upon the sale or other taxable disposition of Common Shares, a U.S. Holder generally will recognize capital gain or loss in an amount equal to the difference between (a) the amount of cash plus the fair market value of any property received and (b) its tax basis in such Common Shares sold or otherwise disposed of. Such gain generally will be treated as “U.S. source” for purposes of applying the U.S. foreign tax credit rules unless the gain is subject to tax in Canada and is re-sourced as “foreign source” under the Canada - US Tax Treaty and such U.S. Holder elects to treat such gain or loss as “foreign source” (see a more

detailed discussion at “Foreign Tax Credit” below). Any such gain or loss generally will be capital gain or loss, which will be long-term capital gain or loss if, at the time of the sale or other disposition, such Common Shares are held for more than one year. Preferential tax rates apply to long-term capital gains of a U.S. Holder that is an individual, estate, or trust. There are currently no preferential tax rates for long-term capital gains of a U.S. Holder that is a corporation. Deductions for capital losses are subject to significant limitations under the Code.

Passive Foreign Investment Company (PFIC) Rules

If the Company is considered a PFIC within the meaning of Section 1297 of the Code at any time during a U.S. Holder’s holding period, then certain different and potentially adverse tax consequences would apply to such U.S. Holder’s acquisition, ownership and disposition of Common Shares.

PFIC Status of the Company

The Company generally will be a PFIC if, for a given tax year, (a) 75% or more of the gross income of the Company for such tax year is passive income or (b) 50% or more of the assets held by the Company either produce passive income or are held for the production of passive income, based on the fair market value of such assets. “Gross income” generally includes all revenues less the cost of goods sold plus income from investments and from incidental or outside operations or sources, and “passive income” includes, for example, dividends, interest, certain rents and royalties, certain gains from the sale of shares and securities, and certain gains from commodities transactions. Active business gains arising from the sale of commodities generally are excluded from passive income if substantially all of a foreign corporation’s commodities are in trade or inventory, depreciable property used in a trade or business, or supplies regularly used or consumed in a trade or business, and certain other requirements are satisfied.

For purposes of the PFIC income test and asset test described above, if the Company owns, directly or indirectly, 25% or more of the total value of the outstanding shares of another corporation, the Company will be treated as if it (a) held a proportionate share of the assets of such other corporation and (b) received directly a proportionate share of the income of such other corporation. In addition, for purposes of the PFIC income test and asset test described above, “passive income” does not include any interest, dividends, rents or royalties that are received or accrued by the Company from a “related person” (as defined in Section 954(d)(3) of the Code), to the extent such items are properly allocable to the income of such related person that is not passive income.

Under certain attribution rules, if the Company is a PFIC, U.S. Holders will be deemed to own their proportionate share of any subsidiary of the Company which is also a PFIC (a “Subsidiary PFIC”), and will be subject to U.S. federal income tax on (a) a distribution on the shares of a Subsidiary PFIC and (b) a disposition of shares of a Subsidiary PFIC, both as if the U.S. Holder directly held the shares of such Subsidiary PFIC.

Based on an analysis of the Company’s activities and income and assets, the Company believes that it was a PFIC for its taxable year ended December 31, 2025, and may continue to be classified as a PFIC for the current taxable year and the foreseeable future. No opinion of legal counsel or ruling from the IRS concerning the status of the Company as a PFIC has been obtained or is currently planned to be requested. The determination of whether the Company (or a subsidiary of the Company) was, or will be, a PFIC for a tax year depends, in part, on the application of complex U.S. federal income tax rules, which are subject to differing interpretations. In addition, whether the Company (or subsidiary) will be a PFIC for any tax year depends on the assets and income of the Company (and each such subsidiary) over the course of each such tax year and, as a result, cannot be predicted with certainty as of the date of this document. Accordingly, there can be no assurance that the IRS will not challenge any determination made by the Company (or subsidiary) concerning its PFIC status or that the Company (and any subsidiary) was not, or will not be, a PFIC for any tax year. U.S. Holders should consult their own tax advisors regarding the PFIC status of the Company and any subsidiary of the Company.

Default PFIC Rules under Section 1291 of the Code

If the Company is a PFIC, the U.S. federal income tax consequences to a U.S. Holder of the acquisition, ownership and disposition of Common Shares will depend on whether such U.S. Holder makes a qualified electing fund election (a “QEF Election”) or makes a mark-to-market election under Section 1296 of the Code (a “Mark-to-Market Election”) with respect to its Common Shares. A U.S. Holder that does not make either a QEF Election or a Mark-to-Market Election will be referred to in this summary as a “Non-Electing U.S. Holder”.

A Non-Electing U.S. Holder will be subject to the rules of Section 1291 of the Code with respect to (a) any gain recognized on the sale or other taxable disposition of the Common Shares and (b) any excess distribution paid on the Common Shares. A distribution generally will be an “excess distribution” to the extent that such distribution (together with all other distributions received in the current tax year) exceeds 125% of the average distributions received during the three preceding tax years (or during a U.S. Holder’s holding period for the Common Shares, if shorter).

If the Company is a PFIC, under Section 1291 of the Code any gain recognized on the sale or other taxable disposition of Common Shares (including an indirect disposition of shares of a Subsidiary PFIC), and any excess distribution paid on the Common Shares (or a distribution by a Subsidiary PFIC to its shareholder that is deemed to be received by a U.S. Holder) must be ratably allocated to each day of a Non-Electing U.S. Holder’s holding period for the Common Shares. The amount of any such gain or excess distribution allocated to the tax year of disposition or excess distribution and to years before the Company became a PFIC, if any, would be taxed as ordinary income. The amounts allocated to any other tax year would be subject to U.S. federal income tax at the highest tax applicable to ordinary income in each such year, and an interest charge would be imposed on the tax liability for each such year, calculated as if such tax liability had been due in each such year. A Non-Electing U.S. Holder that is not a corporation must treat any such interest paid as “personal interest,” which is not deductible.

If the Company is a PFIC for any tax year during which a Non-Electing U.S. Holder holds Common Shares, the Company will continue to be treated as a PFIC with respect to such Non-Electing U.S. Holder, regardless of whether the Company ceases to be a PFIC in one or more subsequent years. If the Company ceases to be a PFIC, a Non-Electing U.S. Holder may terminate this deemed PFIC status with respect to the Common Shares by electing to recognize gain (which will be taxed under the rules of Section 1291 of the Code discussed above) as if such Common Shares were sold on the last day of the last tax year for which the Company was a PFIC.

QEF Election

In the event the Company is a PFIC and a U.S. Holder makes a QEF Election for the first tax year in which its holding period of its Common Shares begins, such U.S. Holder generally will not be subject to the rules of Section 1291 of the Code discussed above with respect to its Common Shares. However, a U.S. Holder that makes a QEF Election will be subject to U.S. federal income tax on such U.S. Holder’s pro rata share of (a) the net capital gain of the Company, which will be taxed as long-term capital gain to such U.S. Holder, and (b) the ordinary earnings of the Company, which will be taxed as ordinary income to such U.S. Holder. Generally, “net capital gain” is the excess of (a) net long-term capital gain over (b) net short-term capital gain, and “ordinary earnings” are the excess of (a) “earnings and profits” over (b) net capital gain. A U.S. Holder that makes a QEF Election will be subject to U.S. federal income tax on such amounts for each tax year in which the Company is a PFIC, regardless of whether such amounts are actually distributed to such U.S. Holder by the Company. However, a U.S. Holder that makes a QEF Election may, subject to certain limitations, elect to defer payment of current U.S. federal income tax on such amounts, subject to an interest charge. If such U.S. Holder is not a corporation, any such interest paid will be treated as “personal interest,” which is not deductible.

A U.S. Holder that makes a QEF Election generally (a) may receive a tax-free distribution from the Company to the extent that such distribution represents “earnings and profits” of the Company that were previously included in income by the U.S. Holder because of such QEF Election and (b) will adjust such U.S. Holder’s tax basis in

the Common Shares to reflect the amount included in income or allowed as a tax-free distribution because of such QEF Election. In addition, a U.S. Holder that makes a QEF Election generally will recognize capital gain or loss on the sale or other taxable disposition of Common Shares.

The procedure for making a QEF Election, and the U.S. federal income tax consequences of making a QEF Election, will depend on whether such QEF Election is timely. A QEF Election will be treated as “timely” if it is made for the first year in the U.S. Holder’s holding period for the Common Shares in which the Company was a PFIC. A U.S. Holder may make a timely QEF Election by filing the appropriate QEF Election documents at the time such U.S. Holder files a U.S. federal income tax return for such year.

A QEF Election will apply to the tax year for which such QEF Election is made and to all subsequent tax years, unless such QEF Election is invalidated or terminated or the IRS consents to revocation of such QEF Election. If a U.S. Holder makes a QEF Election and, in a subsequent tax year, the Company ceases to be a PFIC, the QEF Election will remain in effect (although it will not be applicable) during those tax years in which the Company is not a PFIC. Accordingly, if the Company becomes a PFIC in a subsequent tax year, the QEF Election will be effective, and the U.S. Holder will be subject to the QEF rules described above during a subsequent tax year in which the Company qualifies as a PFIC.

The Company intends to make available to U.S. Holders, upon their written request, all information and documentation that a U.S. Holder making a QEF Election with respect to the Company is required to obtain for U.S. federal income tax purposes. Such information may be included on the Company’s website. However, U.S. Holders should be aware that the Company can provide no assurances that it will provide any such information relating to any Subsidiary PFIC. Because the Company may own shares in one or more Subsidiary PFICs and may acquire shares in one or more Subsidiary PFICs in the future, U.S. Holders will continue to be subject to the rules discussed above with respect to the taxation of gains and excess distributions with respect to any Subsidiary PFIC for which the U.S. Holders do not obtain the required information to file a QEF Election. U.S. Holders should consult their own tax advisor regarding the availability of, and procedure for making, a QEF Election with respect to the Company and any Subsidiary PFIC.

Mark-to-Market Election

A U.S. Holder may make a Mark-to-Market Election only if the Common Shares are “marketable stock” as defined in Section 1296(e). The Common Shares generally will be “marketable stock” if they are regularly traded on (a) a national securities exchange that is registered with the SEC; (b) the national market system established pursuant to section 11A of the Securities and Exchange Act of 1934; or (c) a foreign securities exchange that is regulated or supervised by a governmental authority of the country in which the market is located, provided that (i) such foreign exchange has trading volume, listing, financial disclosure and other requirements and the laws of the country in which such foreign exchange is located, together with the rules of such foreign exchange, ensure that such requirements are actually enforced; and (ii) the rules of such foreign exchange ensure active trading of listed shares. If such shares are traded on such a qualified exchange or other market, such shares generally will be “regularly traded” for any calendar year during which shares are traded, other than in de minimis quantities, on at least 15 days during each calendar quarter. Each U.S. Holder should consult its own tax advisor regarding whether the Common Shares constitute marketable stock.

A U.S. Holder that makes a Mark-to-Market Election with respect to its Common Shares generally will not be subject to the rules of Section 1291 of the Code discussed above. However, if a U.S. Holder does not make a Mark-to-Market Election beginning in the first tax year of such U.S. Holder’s holding period for Common Shares or such U.S. Holder has not made a timely QEF Election, the rules of Section 1291 of the Code discussed above will apply to certain dispositions of, and distributions on, the Common Shares.

A U.S. Holder that makes a Mark-to-Market Election will include in ordinary income, for each tax year in which the Company is a PFIC, an amount equal to the excess, if any, of (a) the fair market value of the Common

Shares, as of the close of such tax year over (b) such U.S. Holder’s tax basis in such Common Shares. A U.S. Holder that makes a Mark-to-Market Election will be allowed a deduction in an amount equal to the excess, if any, of (i) such U.S. Holder’s adjusted tax basis in the Common Shares over (ii) the fair market value of such Common Shares (but only to the extent of the net amount of previously included income as a result of the Mark-to-Market Election for prior tax years).

U.S. Holders that make a Mark-to-Market Election generally also will adjust their tax basis in the Common Shares to reflect the amount included in gross income or allowed as a deduction because of such Mark-to-Market Election. In addition, upon a sale or other taxable disposition of Common Shares, a U.S. Holder that makes a Mark-to-Market Election will recognize ordinary income or loss (not to exceed the excess, if any, of (a) the amount included in ordinary income because of such Mark-to-Market Election for prior tax years over (b) the amount allowed as a deduction because of such Mark-to-Market Election for prior tax years).

A Mark-to-Market Election applies to the tax year in which such Mark-to-Market Election is made and to each subsequent tax year, unless the Common Shares cease to be “marketable stock” or the IRS consents to revocation of such election. U.S. Holders should consult their own tax advisors regarding the availability of, and procedure for making, a Mark-to-Market Election.

Although a U.S. Holder may be eligible to make a Mark-to-Market Election with respect to Common Shares, no such election may be made with respect to the shares of any Subsidiary PFIC that a U.S. Holder is treated as owning because such stock is not “marketable stock”. Hence, the Mark-to-Market Election will not be effective to eliminate the interest charge described above with respect to deemed dispositions of Subsidiary PFIC shares or distributions from a Subsidiary PFIC.

Other PFIC Rules

Under Section 1291(f) of the Code, the IRS has issued proposed Treasury Regulations that, subject to certain exceptions, would cause a U.S. Holder that had not made a timely QEF Election to recognize gain (but not loss) upon certain transfers of Common Shares that would otherwise be tax-deferred (e.g., gifts and exchanges pursuant to corporate reorganizations) in the event the Company is a PFIC during such U.S. Holder’s holding period for the relevant shares. However, the specific U.S. federal income tax consequences to a U.S. Holder may vary based on the manner in which Common Shares are transferred.

Certain additional adverse rules will apply with respect to a U.S. Holder if the Company is a PFIC, regardless of whether such U.S. Holder makes a QEF Election. For example, under Section 1298(b)(6) of the Code, a U.S. Holder that uses Common Shares as security for a loan will, except as may be provided in Treasury Regulations, be treated as having made a taxable disposition of such Common Shares.

In any year in which the Company is classified as a PFIC, a U.S. Holder will be required to file an annual report with the IRS containing such information as Treasury Regulations and/or other IRS guidance may require. U.S. Holders should consult their own tax advisors regarding the requirements of filing such information returns under these rules, including the requirement to file an IRS Form 8621.

In addition, a U.S. Holder who acquires Common Shares from a decedent will not receive a “step up” in tax basis of such Common Shares to fair market value unless such decedent had a timely and effective QEF Election in place.

Special rules also apply to the amount of foreign tax credit that a U.S. Holder may claim on a distribution from a PFIC.

The PFIC rules are complex, and U.S. Holders should consult their own tax advisors regarding the PFIC rules and how they may affect the U.S. federal income tax consequences of the acquisition, ownership, and disposition of Common Shares in the event the Company is a PFIC at any time during such holding period for such Common Shares.

Additional Considerations

Receipt of Foreign Currency

The amount of any distribution paid in foreign currency to a U.S. Holder in connection with the ownership of Common Shares, or on the sale, exchange or other taxable disposition of Common Shares, generally will be equal to the U.S. dollar value of such foreign currency based on the exchange rate applicable on the date of receipt or, if applicable, the date of settlement if the Common Shares are traded on an established securities market (regardless of whether such foreign currency is converted into U.S. dollars at that time). If the foreign currency received is not converted into U.S. dollars on the date of receipt, a U.S. Holder will have a basis in the foreign currency equal to its U.S. dollar value on the date of receipt. A U.S. Holder that receives foreign currency and converts such foreign currency into U.S. dollars at a conversion rate other than the rate in effect on the date of receipt may have a foreign currency exchange gain or loss, which generally would be treated as U.S. source ordinary income or loss for foreign tax credit purposes. Different rules apply to U.S. Holders who use the accrual method of tax accounting. U.S. Holders should consult their own U.S. tax advisors regarding the U.S. federal income tax consequences of receiving, owning and disposing of foreign currency.

Foreign Tax Credit

Dividends paid on the Common Shares will be treated as foreign-source income, and generally will be treated as “passive category income” or “general category income” for U.S. foreign tax credit purposes. Any gain or loss recognized on a sale or other disposition of Common Shares generally will be United States source gain or loss. Certain U.S. Holders that are eligible for the benefits of the Canada - US Tax Treaty may elect to treat such gain or loss as Canadian source gain or loss for U.S. foreign tax credit purposes. The Code applies various complex limitations on the amount of foreign taxes that may be claimed as a credit by U.S. taxpayers. In addition, Treasury Regulations that apply to foreign taxes paid or accrued (the “Foreign Tax Credit Regulations”) impose additional requirements for Canadian withholding taxes to be eligible for a foreign tax credit, and there can be no assurance that those requirements will be satisfied. The Treasury Department has released guidance temporarily pausing the application of certain of the Foreign Tax Credit Regulations.

Subject to the PFIC rules and the Foreign Tax Credit Regulations, each as discussed above, a U.S. Holder that pays (whether directly or through withholding) Canadian income tax with respect to dividends paid on the Common Shares generally will be entitled, at the election of such U.S. Holder, to receive either a deduction or a credit for such Canadian income tax. Generally, a credit will reduce a U.S. Holder’s U.S. federal income tax liability on a dollar-for-dollar basis, whereas a deduction will reduce a U.S. Holder’s income that is subject to U.S. federal income tax. This election is made on a year-by-year basis and applies to all foreign taxes paid (whether directly or through withholding) by a U.S. Holder during a year. The foreign tax credit rules are complex and involve the application of rules that depend on a U.S. Holder’s particular circumstances. Accordingly, each U.S. Holder should consult its own U.S. tax advisor regarding the foreign tax credit rules.

Information Reporting, Backup Withholding Tax

Under U.S. federal income tax law and Treasury Regulations, certain categories of U.S. Holders must file information returns with respect to their investment in, or involvement in, a foreign corporation. For example, U.S. return disclosure obligations (and related penalties) are imposed on individuals who are U.S. Holders that hold certain specified foreign financial assets in excess of certain threshold amounts. The definition of specified foreign financial assets includes not only financial accounts maintained in foreign financial institutions, but also, unless held in accounts maintained by a financial institution, any shares or security issued by a non-U.S. person, any financial instrument or contract held for investment that has an issuer or counterparty other than a U.S. person and any interest in a non-U.S. entity. U.S. Holders may be subject to these reporting requirements unless their Common Shares are held in an account at certain financial institutions. Penalties for failure to file certain of these information returns are substantial. U.S. Holders should consult their own tax advisors regarding the requirements of filing information returns, including the requirement to file an IRS Form 8938.

Payments made within the U.S. or by a U.S. payor or U.S. middleman, of dividends on, and proceeds arising from the sale or other taxable disposition of Common Shares will generally be subject to information reporting and backup withholding tax if a U.S. Holder (a) fails to furnish such U.S. Holder’s correct U.S. taxpayer identification number (generally on IRS Form W-9), (b) furnishes an incorrect U.S. taxpayer identification number, (c) is notified by the IRS that such U.S. Holder has previously failed to properly report items subject to backup withholding tax, or (d) fails to certify, under penalty of perjury, that such U.S. Holder has furnished its correct U.S. taxpayer identification number and that the IRS has not notified such U.S. Holder that it is subject to backup withholding tax. However, certain exempt persons generally are excluded from these information reporting and backup withholding rules. Backup withholding is not an additional tax. Any amounts withheld under the U.S. backup withholding tax rules will be allowed as a credit against a U.S. Holder’s U.S. federal income tax liability, if any, or will be refunded, if such U.S. Holder furnishes required information to the IRS in a timely manner.

The discussion of reporting requirements set forth above is not intended to constitute a complete description of all reporting requirements that may apply to a U.S. Holder. A failure to satisfy certain reporting requirements may result in an extension of the time period during which the IRS can assess a tax, and under certain circumstances, such an extension may apply to assessments of amounts unrelated to any unsatisfied reporting requirement. Each U.S. Holder should consult its own tax advisors regarding the information reporting and backup withholding rules.

THE ABOVE SUMMARY IS NOT INTENDED TO CONSTITUTE A COMPLETE ANALYSIS OF ALL TAX CONSIDERATIONS APPLICABLE TO U.S. HOLDERS WITH RESPECT TO THE ACQUISITION, OWNERSHIP AND DISPOSITION OF COMMON SHARES. U.S. HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE TAX CONSIDERATIONS APPLICABLE TO THEM IN LIGHT OF THEIR OWN PARTICULAR CIRCUMSTANCES.

Item 15.

Indemnification of Directors and Officers.

enCore Energy Corp. (“we”, “us” or “the Company”) is subject to the provisions of Part 5, Division 5 of the BCBCA.

Under Section 160 of the BCBCA, we may, subject to Section 163 of the BCBCA:

(1)	indemnify an individual who:

•

is or was a director or officer of the Company;

•

is or was a director or officer of another corporation (i) at a time when such corporation is or was an affiliate of the Company; or (ii) at our request, or

•

at our request, is or was, or holds or held a position equivalent to that of, a director or officer of a partnership, trust, joint venture or other unincorporated entity,

and including, subject to certain limited exceptions, the heirs and personal or other legal representatives of that individual (collectively, an “eligible party”), against all eligible penalties to which the eligible party is or may be liable; and

(2)	after final disposition of an eligible proceeding, pay the expenses actually and reasonably incurred by an eligible party in respect of that proceeding, where:

“eligible penalty” means a judgment, penalty or fine awarded or imposed in, or an amount paid in settlement of, and eligible proceeding.

“eligible proceeding” means a proceeding in which an eligible party or any of the heirs and personal or other legal representatives of the eligible party, by reason of the eligible party being or having been a director or officer of, or holding or having held a position equivalent to that of a director or officer of, the Company or an associated corporation (a) is or may be joined as a party, or (b) is or may be liable for or in respect of a judgment, penalty or fine in, or expenses related to, the proceeding.

II-1

“expenses” includes costs, charges and expenses, including legal and other fees, but does not include judgments, penalties, fines or amounts paid in settlement of a proceeding.

“proceeding” includes any legal proceeding or investigative action, whether current, threatened , pending or completed.

Under Section 161 of the BCBCA, and subject to Section 163 of the BCBCA, we must, after the final disposition of an eligible proceeding, pay the expenses actually and reasonably incurred by an eligible party in respect of that proceeding if the eligible party (a) has not been reimbursed for those expenses, and (b) is wholly successful, on the merits or otherwise, in the outcome of the proceeding or is substantially successful on the merits in the outcome of the proceeding.

Under Section 162 of the BCBCA, and subject to Section 163 of the BCBCA, we may pay, as they are incurred in advance of the final disposition of an eligible proceeding, the expenses actually and reasonably incurred by an eligible party in respect of the proceeding, provided that we must not make such payments unless we first receive from the eligible party a written undertaking that, if it is ultimately determined that the payment of expenses is prohibited under Section 163 of the BCBCA, the eligible party will repay the amounts advanced.

Under Section 163 of the BCBCA, we must not indemnify an eligible party against eligible penalties to which the eligible party is or may be liable under Section 160(a) of the BCBCA, or pay the expenses of an eligible party in respect of that proceeding under Sections 160(b), 161 or 162 of the BCBCA, as the case may be, if any of the following circumstances apply:

•

if the indemnity or payment is made under an earlier agreement to indemnify or pay expenses and, at the time that the agreement to indemnify or pay expenses was made, we were prohibited from giving the indemnity or paying the expenses by our memorandum or Articles;

•

if the indemnity or payment is made otherwise than under an earlier agreement to indemnify or pay expenses and, at the time that the indemnity or payment is made, we are prohibited from giving the indemnity or paying the expenses by our memorandum or Articles;

•

if, in relation to the subject matter of the eligible proceeding, the eligible party did not act honestly and in good faith with a view to the best interests of the Company or the associated corporation, as the case may be;

•

in the case of an eligible proceeding other than a civil proceeding, if the eligible party did not have reasonable grounds for believing that the eligible party’s conduct in respect of which the proceeding was brought was lawful; or

•

if an eligible proceeding is brought against an eligible party by or on behalf of the Company or by or on behalf of an associated corporation, we must not either indemnify the eligible party against eligible penalties to which the eligible party is or may be liable under Section 160(a) of the BCBCA, or pay the expenses of the eligible party under Sections 160(b), 161 or 162 of the BCBCA, as the case may be, in respect of the proceeding.

Under Section 164 of the BCBCA, and despite any other provision of Part 5, Division 5 of the BCBCA and whether or not payment of expenses or indemnification has been sought, authorized or declined under Part 5, Division 5 of the BCBCA, on application of the Company or an eligible party, the Supreme Court of British Columbia may do one or more of the following:

•

order us to indemnify an eligible party against any liability incurred by the eligible party in respect of an eligible proceeding;

•

order us to pay some or all of the expenses incurred by an eligible party in respect of an eligible proceeding;

•

order the enforcement of, or payment under, an agreement of indemnification entered into by us;

II-2

•

order us to pay some or all of the expenses actually and reasonably incurred by any person in obtaining an order under Section 164 of the BCBCA; or

•

make any other order the court considers appropriate.

Section 165 of the BCBCA provides that we may purchase and maintain insurance for the benefit of an eligible party or the heirs and personal or other legal representatives of the eligible party against any liability that may be incurred by reason of the eligible party being or having been a director or officer of, or holding or having held a position equivalent to that of a director or officer of, the Company or an associated corporation.

Under our Articles, and subject to the BCBCA, we must indemnify a director, former director or alternate director and his or her heirs and personal or other legal representatives against all eligible penalties to which such person is or may be liable, and we must, after the final disposition of an eligible proceeding, pay the expenses actually and reasonably incurred by such person in respect of that proceeding. Each director and officer is deemed to have contracted with the Company on the terms of the indemnity contained in our Articles.

Under our Articles, and subject to the BCBCA, we may agree to indemnify and may indemnify any person (including an eligible party). We have entered into indemnity agreements with our directors and officers.

Pursuant to our Articles, the failure of a director, alternate director or officer to comply with the BCBCA or our Articles does not, of itself, invalidate any indemnity to which he or she is entitled under our Articles.

Under our Articles, we may purchase and maintain insurance for the benefit of a person (or his or her heirs or legal personal representatives) who:

•

is or was a director, alternate director, officer, employee or agent of the Company;

•

is or was a director, alternate director, officer, employee or agent of another corporation at a time when such corporation is or was an affiliate of the Company, or

•

at our request, is or was, or holds or held a position equivalent to that of, a director, alternate director or officer of a corporation or a partnership, trust, joint venture or other unincorporated entity,

against any liability incurred by him or her as a director, alternate director, officer, employee or agent or person who holds or held such equivalent position.

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

UNDERTAKING AND CONSENT TO SERVICE OF PROCESS

Item 17.

Undertaking.

(a)	The undersigned registrant hereby undertakes:

(1)

To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)

To include any prospectus required by section 10(a)(3) of the Securities Act;

(ii)

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered

II-4

(if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (i), (ii) and (iii) do not apply if the registration statement is on Form S-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)

That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the Securities offered therein, and the offering of such Securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)

To remove from registration by means of a post-effective amendment any of the Securities being registered which remain unsold at the termination of the offering.

(5)

That, for the purpose of determining liability under the Securities Act to any purchaser:

(i)

Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii)

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of Securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the Securities in the registration statement to which that prospectus relates, and the offering of such Securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(6)

That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the Securities: the undersigned registrant undertakes that in a primary offering of Securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the Securities to the purchaser, if the Securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)

Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

II-5

(ii)

Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)

The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its Securities provided by or on behalf of the undersigned registrant; and

(iv)

Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b)

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the Securities offered therein, and the offering of such Securities at that time shall be deemed to be the initial bona fide offering thereof.

(h)

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the Securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(j)

The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Indenture Act in accordance with the rules and regulations prescribed by the SEC under Section 305(b)(2) of the Indenture Act.
