WHEATON PRECIOUS METALS CORP.

Up to US$300,000,000 of Common Shares

This prospectus supplement (the “prospectus supplement”) of Wheaton Precious Metals Corp. (“Wheaton” or the “Corporation”), together with the accompanying short form base shelf prospectus dated April 22, 2021 (the “prospectus”) qualifies the distribution (the “Offering”) of common shares (the “Offered Shares”) of the Corporation having an aggregate sale price of up to US$300,000,000 (or the equivalent in Canadian dollars determined using the daily exchange rate posted by the Bank of Canada on the date the Offered Shares are sold). See “Plan of Distribution” and “Description of Common Shares”.

The outstanding common shares (the “Common Shares”) of the Corporation are listed and posted for trading on the Toronto Stock Exchange (the “TSX”), listed on the New York Stock Exchange (the “NYSE”) and admitted to trading on the London Stock Exchange (“LSE”), in each case under the trading symbol “WPM”. On May 11, 2021, the last trading day prior to the date of this prospectus supplement, the closing price of the Common Shares on the TSX was C$53.94, on the NYSE was US$44.59 and on the LSE was £31.20. The TSX has conditionally approved the listing of the Offered Shares distributed under the Offering, subject to Wheaton fulfilling all of the requirements of the TSX. The NYSE has authorized the listing of the Offered Shares distributed under the Offering, subject to official notice of issuance. Following the issuance of any Offered Shares, Wheaton will make the required filings and applications to the Financial Conduct Authority (the “FCA”) with respect to the listing of the Offered Shares distributed under the Offering on the standard segment of the FCA’s Official List and to the LSE for admission of the Offered Shares to trading on the Main Market of the LSE.

Wheaton previously entered into an ATM equity offering sales agreement dated April 16, 2020, as amended on May 12, 2021 (the “Sales Agreement”) with Merrill Lynch Canada Inc., BMO Nesbitt Burns Inc., RBC Dominion Securities Inc., Scotia Capital Inc., CIBC World Markets Inc., TD Securities Inc., National Bank Financial Inc., Eight Capital, Raymond James Ltd. and Canaccord Genuity Corp. (the “Canadian Agents”) and BofA Securities, Inc., BMO Capital Markets Corp., RBC Capital Markets, LLC, Scotia Capital (USA) Inc., MUFG Securities Americas Inc. and Mizuho Securities USA LLC (the “U.S. Agents” and, together with the Canadian Agents, the “Agents”) pursuant to which the Corporation may distribute up to US$300,000,000 (or the equivalent in Canadian dollars determined using the daily exchange rate posted by the Bank of Canada on the date the Offered Shares are sold) of Offered Shares in the Offering from time to time through the Agents, as agents, in accordance with the terms of the Sales Agreement. On April 16, 2020, the Corporation filed a prospectus supplement to an existing short form base shelf prospectus dated May 3, 2019 (the “2019 Base Shelf”) in connection with the Sales Agreement. In accordance with section 3(t) of the Sales Agreement, prior to the 25 month anniversary of the 2019 Base Shelf, on April 22, 2021, Wheaton filed the accompanying prospectus and a registration statement on Form F-10, of which the prospectus is a part, with the Securities and Exchange Commission (the “SEC”) in the United States under the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”), which prospectus replaces and supersedes the 2019 Base Shelf. Accordingly, this prospectus supplement has been filed in order to qualify and permit the Corporation to offer and sell the Offered Shares pursuant to the Offering in accordance with the terms of the Sales Agreement under this prospectus supplement and the accompanying prospectus. This prospectus supplement replaces and supersedes the previous prospectus supplement dated April 16, 2020. See “Plan of Distribution”.

The Offering is being made concurrently in Canada under the terms of this prospectus supplement and in the United States under the terms of the Corporation’s prospectus supplement filed pursuant to General Instruction II.L of Form F-10 under the U.S. Securities Act, supplementing the base prospectus that forms a part of the Corporation’s registration statement (the “Registration Statement”) on Form F-10 filed with the SEC. Sales of Offered Shares, if any, under this prospectus supplement and the prospectus are anticipated to be made

through an Agent acting as sales agent by means of (i) ordinary brokers’ transactions on the NYSE or another United States “marketplace”, as such term is defined in National Instrument 21-101 – Marketplace Operation (“NI 21-101”), upon which the Offered Shares are listed, quoted or otherwise traded (“U.S. marketplace”), (ii) ordinary brokers’ transactions on the TSX that constitute an “at-the-market distribution” under National Instrument 44-102 – Shelf Distributions (“NI 44-102”), (iii) in the case of Canadian Agents, another Canadian “marketplace”, as such term is defined in NI 21-101, upon which the Offered Shares are listed, quoted or otherwise traded (“Canadian marketplace” and together with the U.S. marketplace, “marketplaces” and each, a “marketplace”), or (iv) in the case of U.S. Agents, otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. As a result, prices may vary as between purchasers and during the period of distribution. There is no minimum amount of funds that must be raised under the Offering. This means that the Offering may terminate after only raising a small portion of the offering amount set out above, or none at all. The Canadian Agents will only sell Common Shares on marketplaces in Canada. The U.S. Agents will not, directly or indirectly, advertise or solicit offers to purchase or sell the Offered Shares in Canada or sell the Offered Shares on any Canadian marketplace. See “Plan of Distribution”.

The Offering is being made by a Canadian issuer that is permitted, under a multijurisdictional disclosure system adopted by the securities regulatory authorities in Canada and the United States, to prepare this prospectus supplement and the accompanying prospectus in accordance with the disclosure requirements of Canada. Prospective investors in the United States should be aware that such requirements are different from those of the United States. The financial statements incorporated herein have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”).

Prospective investors should be aware that the acquisition of the securities described herein may have tax consequences both in the United States and in Canada, including the Canadian federal income tax consequences applicable to a foreign controlled Canadian corporation that acquires Offered Shares. Such consequences for investors who are residents in, or citizens of, the United States or Canada may not be fully described herein. Investors should read the tax discussion in this prospectus supplement and consult their own tax advisors with respect to their particular circumstances. See “Certain Canadian Federal Income Tax Considerations” and “Certain United States Federal Income Tax Considerations”.

The enforcement by investors of civil liabilities under the United States federal securities laws may be affected adversely by the fact that the Corporation is organized under the laws of Ontario, Canada, that some or all of its officers and directors may be residents of a foreign country, that some or all of the experts named in this prospectus supplement and in the accompanying prospectus may be residents of a foreign country, and that a substantial portion of the assets of the Corporation are and said persons may be located outside the United States.

These securities have not been approved or disapproved by the SEC nor any state or Canadian securities commission nor has the SEC or any state or Canadian securities commission passed upon the accuracy or adequacy of this prospectus supplement or the accompanying prospectus. Any representation to the contrary is a criminal offence.

This document does not constitute an offer or any part of any offer of transferable securities in the UK or to the public within the meaning of section 102B of the UK Financial Services and Markets Act 2000, as amended (“FSMA”) or otherwise. Accordingly, this document does not constitute a prospectus or prospectus equivalent document for the purposes of Article 3 of the UK version of Regulation (EU) 2017/1129, which is part of UK law by virtue of the European Union (Withdrawal) Act 2018 or otherwise, and has not been drawn up in accordance with the UK Prospectus Regulation Rules of the UK Financial Conduct Authority made under section 73A of FSMA or filed with or approved by the UK Financial Conduct Authority. Nothing herein shall be construed as any offer, invitation or recommendation to purchase, sell or subscribe for any securities in the United Kingdom.

An investment in the Offered Shares is highly speculative and involves significant risks that should be carefully considered by prospective investors before purchasing such securities. The risks outlined in this prospectus supplement, the accompanying prospectus and in the documents incorporated by reference herein and therein should be carefully reviewed and considered by prospective investors in connection with an investment in the Offered Shares.

Wheaton will pay the Agents a commission for their services in acting as agents in connection with the sale of Offered Shares pursuant to the Sales Agreement (the “Commission”). The amount of the Commission shall not exceed 2.0% of the gross sales price for such Offered Shares sold, and will be paid in United States dollars. The total expenses that the Corporation incurred related to the commencement of the Offering, excluding the Commission payable to the Agents under the terms of the Sales Agreement, was approximately US$900,000. See “Plan of Distribution”.

No Agent involved in the at-the-market distribution, and no person or company acting jointly or in concert with an 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 or this prospectus supplement, including selling an aggregate number or principal amount of securities that would result in the Agent creating an over-allocation position in the securities.

In connection with the Offering, the Corporation may be considered to be a “connected issuer” within the meaning of National Instrument 33-105 – Underwriting Conflicts (“NI 33-105”) to each of Merrill Lynch Canada Inc., BMO Nesbitt Burns Inc., RBC Dominion Securities Inc., Scotia Capital Inc., CIBC World Markets Inc., TD Securities Inc., National Bank Financial Inc., BofA Securities, Inc., BMO Capital Markets Corp., RBC Capital Markets, LLC, Scotia Capital (USA) Inc., MUFG Securities Americas Inc. and Mizuho Securities USA LLC. Affiliates of each of the aforementioned Agents are lenders to the Corporation. See “Relationship Between the Corporation and Certain Agents (Conflicts of Interest)”.

Prospective investors are advised that it may not be possible for investors to enforce judgments obtained in Canada against any person or company that is incorporated, continued or otherwise organized under the laws of a foreign jurisdiction or resides outside of Canada, even if the party has appointed an agent for service of process.

The Corporation’s head office is located at Suite 3500 – 1021 West Hastings Street, Vancouver, British Columbia, V6E 0C3 and its registered office is located at Suite 2100, 40 King Street West, Toronto, Ontario, M5H 3C2.

such other assumptions and factors as set out herein.

S-3

Although Wheaton has attempted to identify important factors that could cause actual results, level of activity, performance or achievements to differ materially from those contained in forward-looking statements, there may be other factors that cause results, level of activity, performance or achievements not to be as anticipated, estimated or intended. There can be no assurance that forward- looking statements will prove to be accurate and even if events or results described in the forward-looking statements are realized or substantially realized, there can be no assurance that they will have the expected consequences to, or effects on, Wheaton. Accordingly, readers should not place undue reliance on forward-looking statements and are cautioned that actual outcomes may vary. The forward-looking statements included herein are for the purpose of providing investors with information to assist them in understanding Wheaton’s expected financial and operational performance and may not be appropriate for other purposes. Any forward-looking statement speaks only as of the date on which it is made. Wheaton does not undertake to update any forward-looking statements that are included or incorporated by reference herein, except in accordance with applicable securities laws.

CAUTIONARY NOTE TO UNITED STATES INVESTORS REGARDING PRESENTATION OF MINERAL RESERVE AND MINERAL RESOURCE ESTIMATES

This prospectus supplement and the accompanying prospectus, including the documents incorporated by reference herein and therein, have been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of United States securities laws. The terms “mineral reserve”, “proven mineral reserve” and “probable mineral reserve” are Canadian mining terms defined in accordance with Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) — CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the “CIM Definition Standards”). These definitions differ from the definitions in Industry Guide 7 (“SEC Industry Guide 7”) under the U.S. Securities Act. Under U.S. standards, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Also, under SEC Industry Guide 7 standards, a “final” or “bankable” feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority.

In addition, the terms “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. “Inferred mineral resources” have a great amount of uncertainty as to their existence and as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Disclosure of “contained ounces” in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute “reserves” by SEC standards as in place tonnage and grade without reference to unit measures.

The SEC has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”). These amendments became effective February 25, 2019 (the “SEC Modernization Rules”) with compliance required for the first fiscal year beginning on or after January 1, 2021. Under the SEC Modernization Rules, the historical property disclosure requirements for mining registrants included in SEC Industry Guide 7 will be rescinded and replaced with disclosure requirements in subpart 1300 of SEC Regulation S-K. Following the transition period, as a foreign private issuer that is eligible to file reports with the SEC pursuant to the multi-jurisdictional disclosure system, the Corporation is not required to provide disclosure on its mineral properties under the SEC Modernization Rules and will continue to provide disclosure under NI 43-101.

As a result of the adoption of the SEC Modernization Rules, the SEC will recognize estimates of “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources.” In addition, the SEC has amended its definitions of “proven mineral reserves” and “probable mineral reserves” to be “substantially similar” to the corresponding definitions under the CIM Definition Standards that are required under NI 43-101. However, while the above terms are “substantially similar” to CIM Definition Standards, there are differences in the definitions under the SEC Modernization Rules and the CIM Definition Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Corporation may report as “proven mineral reserves”, “probable mineral reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had the Corporation prepared the reserve or resource estimates under the standards adopted under the SEC Modernization Rules.

Accordingly, information contained in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein that describes the Corporation’s mineral deposits may not be comparable to similar information made public

S-4

by U.S. companies subject to reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.

See “Description of the Business – Technical Information” in the Annual Information Form, which is incorporated by reference herein, for a description of certain of the mining terms used in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein.

THE CORPORATION

Wheaton is a streaming company which generates its revenue primarily from the sale of precious metals. Wheaton enters purchase agreements (“precious metal purchase agreements” or “PMPAs”) to purchase all or a portion of the precious metals or cobalt production from mines located around the globe for an upfront payment and an additional payment upon the delivery of the precious metal.

As of March 31, 2021, the Corporation has entered into 26 long-term purchase agreements (three of which are early deposit precious metal purchase agreements), with 19 different mining companies, for the purchase of precious metals and cobalt relating to 24 mining assets which are currently operating, eight which are at various stages of development and one of which has been placed in care and maintenance, located in 12 countries. Wheaton acquires metal production from the counterparties for an initial upfront payment plus an additional cash payment for each ounce or pound delivered which is fixed by contract, generally at or below the prevailing market price. The primary drivers of the Corporation’s financial results are the volume of metal production at the various mines to which the precious metal purchase agreements relate and the price realized by Wheaton upon sale of the metals received. Attributable metal production as referred to in this prospectus supplement and the documents incorporated by reference herein is the metal production to which Wheaton is entitled pursuant to the various precious metal purchase agreements.

The Corporation is actively pursuing future growth opportunities, primarily by way of entering into additional long-term precious metal purchase agreements. There is no assurance, however, that any potential transaction will be successfully completed. For a further description of the business of the Corporation, see the sections entitled “Corporate Structure” and “Description of the Business” in the Annual Information Form.

RISK FACTORS

Before deciding to invest in the Offered Shares, investors should carefully consider all the information contained in and incorporated or deemed incorporated by reference in this prospectus supplement and the accompanying prospectus. An investment in the Offered Shares is subject to certain risks, including risks related to the business of the Corporation, risks related to mining operations and risks related to the Corporation’s securities described in the documents incorporated or deemed incorporated in the prospectus and herein by reference. See the risk factors below and the “Risk Factors” section of the prospectus and the documents incorporated or deemed incorporated by reference herein and therein.

No certainty regarding the net proceeds to the Corporation

There is no certainty that gross proceeds of US$300,000,000 (or the equivalent in Canadian dollars determined using the daily exchange rate posted by the Bank of Canada on the date the Offered Shares are sold) will be raised under the Offering. The Agents have agreed to use their commercially reasonable efforts to sell, on the Corporation’s behalf, the Offered Shares designated by the Corporation, but the Corporation is not required to request the sale of the maximum amount offered or any amount and, if the Corporation requests a sale, the Agents are not obligated to purchase any Offered Shares that are not sold. As a result of the Offering being made on a commercially

S-7

reasonable efforts basis with no minimum, and only as requested by the Corporation, the Corporation may raise substantially less than the maximum total offering amount or nothing at all.

Broad discretion in the use of proceeds

Management of the Corporation will have broad discretion in the application of the net proceeds from the Offering and could spend the proceeds in ways that do not improve the Corporation’s results of operations or enhance the value of the Common Shares. The failure by management to apply these funds effectively could result in financial losses that could have a material adverse effect on the Corporation’s business and cause the price of the Common Shares to decline. Pending their use, the Corporation may invest the net proceeds from the Offering in a manner that does not produce income or that loses value.

Future sales or issuances of securities

The Corporation may issue additional securities to finance future activities outside of the Offering. The Corporation cannot predict the size of future issuances of securities or the effect, if any, that future issuances and sales of securities will have on the market price of the Common Shares. Sales or issuances of substantial numbers of Common Shares, or the expectation that such sales could occur, may adversely affect prevailing market prices of the Common Shares. In connection with any issuance of Common Shares, investors will suffer dilution to their voting power and the Corporation may experience dilution in its earnings per share.

COVID-19 virus pandemic may heighten other risks

To the extent that the COVID-19 virus pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described herein and in the “Risk Factors” section of the prospectus and the documents incorporated or deemed incorporated by reference herein and therein, including, but not limited to, risks relating to the Corporation such as risks related to commodity prices and commodity markets, commodity price fluctuations, equity price risk associated with the Corporation’s equity investments, credit and liquidity of counterparties to our PMPAs, mine operator concentration, our indebtedness and guarantees, our ability to raise additional capital, our ability to enforce security interests, information systems and cyber security and risks relating to the Mining Operations such as risks related to mineral reserve and mineral resource estimates, production forecasts, impacts of governmental regulations, international operations, availability of infrastructure and employees and challenging global financial conditions.

CONSOLIDATED CAPITALIZATION

There have been no material changes in the share and loan capital of the Corporation, on a consolidated basis, since the date of the Interim Financial Statements. As a result of the Offering, the shareholders’ equity of the Corporation will increase by the amount of the net proceeds of the Offering and the number of issued and outstanding Common Shares will increase by the number of common shares distributed under the Offering.

USE OF PROCEEDS

The Corporation intends to use the net proceeds from the Offering, if any, for funding precious metal purchase agreements and/or other general corporate purposes, including the repayment of indebtedness. The Corporation may, from time to time, issue securities (including equity securities) other than pursuant to this prospectus supplement.

The net proceeds from the Offering, if any, are not determinable in light of the nature of the distribution. Sales of Offered Shares, if any, will be made in transactions that are (i) ordinary brokers’ transactions on the NYSE or another U.S. marketplace, (ii) ordinary brokers’ transactions on the TSX that constitute “at-the-market distributions” as defined in NI 44-102, (iii) in the case of the Canadian Agents, another Canadian marketplace, or (iv) in the case of U.S. Agents, otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. The net proceeds to the Corporation of any given distribution of Offered Shares through the Agents in an “at-the-market distribution” under the Sales Agreement will represent the gross proceeds of the Offering, after deducting the applicable Commission and the expenses of the Offering. The gross proceeds of the Offering will be up to US$300,000,000 (or the equivalent in Canadian dollars determined using the daily exchange rate posted by the Bank of Canada on the date the Offered Shares are sold). There is no minimum amount of funds that must be raised under the Offering. This means that the Offering may terminate after raising only a portion of the Offering amount set out above, or none at all. See “Plan of Distribution”.

S-8

Although the Corporation intends to expend the net proceeds from the Offering as set forth above, there may be circumstances where, for sound business reasons, a reallocation of funds may be prudent or necessary, and may vary materially from that set forth above. In addition, management of the Corporation will have broad discretion with respect to the actual use of the net proceeds from the Offering. See “Risk Factors”.

PLAN OF DISTRIBUTION

The Corporation has entered into the Sales Agreement with the Agents pursuant to which the Corporation may issue and sell from time to time through the Agents, as agents, Offered Shares having an aggregate sale price of up to US$300,000,000 (or the equivalent in Canadian dollars determined using the daily exchange rate posted by the Bank of Canada on the date the Offered Shares are sold) pursuant to instructions provided by the Corporation to the Agents from time to time in accordance with the terms of the Sales Agreement. On April 16, 2020, the Corporation filed a prospectus supplement to the existing 2019 Base Shelf in connection with the Sales Agreement. In accordance with section 3(t) of the Sales Agreement, prior to the 25 month anniversary of the 2019 Base Shelf, Wheaton filed the accompanying prospectus and a registration statement on Form F-10, of which the prospectus is a part, with the SEC in the United States under the U.S. Securities Act, which prospectus replaces and supersedes the 2019 Base Shelf. Accordingly, this prospectus supplement has been filed in order to qualify and permit the Corporation to offer and sell the Offered Shares pursuant to the Offering in accordance with the terms of the Sales Agreement under this prospectus supplement and the accompanying prospectus. This prospectus supplement replaces and supersedes the previous prospectus supplement dated April 16, 2020.

The Offering is being made concurrently in Canada under the terms of this prospectus supplement and in the United States under the terms of the prospectus supplement filed pursuant to General Instruction II.L of Form F-10 under the U.S. Securities Act, supplementing the base prospectus which forms a part of the Registration Statement on Form F-10 filed with the SEC. Sales of Offered Shares, if any, under this prospectus supplement and the prospectus are anticipated to be made through an Agent acting as sales agent by means of (i) ordinary brokers’ transactions on the NYSE or another U.S. marketplace, (ii) ordinary brokers’ transactions on the TSX that constitute an “at-the-market distribution” under NI 44-102, (iii) in the case of Canadian Agents, another Canadian marketplace, or (iv) in the case of U.S. Agents, otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. As a result, prices may vary as between purchasers and during the period of distribution. The Corporation cannot predict the number of Offered Shares that it may sell under the Sales Agreement on the TSX, the NYSE or any other marketplace, or if any Offered Shares will be sold.

There is no minimum amount of funds that must be raised under the Offering. This means that the Offering may terminate after only raising a small portion of the offering amount set out above, or none at all. The Canadian Agents will only sell Offered Shares on Canadian marketplaces. The U.S. Agents will not, directly or indirectly, advertise or solicit offers to purchase or sell the Offered Shares in Canada or sell the Offered Shares on any Canadian marketplace.

The Agents will offer the Offered Shares subject to the terms and conditions of the Sales Agreement from time to time as agreed upon by the Corporation and the Agents. On any day other than a day on which the NYSE or the TSX, as applicable, is closed or scheduled to close prior to its regular weekday closing time (each, a “Trading Day”), the Corporation may sell the Offered Shares through only one Agent and, if it determines to do so, it shall instruct the applicable Agent as to the maximum number of Offered Shares to be sold on such Trading Day and the minimum price per Offered Share at which such Offered Shares may be sold. Subject to the terms and conditions of the Sales Agreement, such Agent will use its commercially reasonable efforts to sell, on the Corporation’s behalf, all of the Offered Shares requested to be sold by the Corporation in accordance with its instruction. Under the Sales Agreement, no Agent has any obligation to purchase as principal for its own account any Offered Shares.

Either the Corporation or the Agent through whom the sale of the Offered Shares is to be made as sales agent on any Trading Day may suspend the Offering upon proper notice to the other party. The Corporation and each Agent with respect to itself has the right, by giving written notice as specified in the Sales Agreement, to terminate the Sales Agreement in such party’s sole discretion at any time.

If acting as sales agent, the applicable Agent will provide written confirmation to the Corporation following the close of trading on each Trading Day on which such Agent has made sales of the Offered Shares under the Sales Agreement setting forth (i) the number of Offered Shares sold on such day, (ii) the aggregate gross sales proceeds of the Offered Shares, (iii) the Commission payable by the Corporation to the Agents with respect to such sales, and (iv) the proceeds payable to the Corporation after deducting transaction fees, transfer taxes or similar taxes or fees imposed by any governmental entity or self-regulatory organization in respect of such sales.

The Corporation will pay the Agents the Commission for their services in acting as agents in connection with the sale of Offered Shares pursuant to the Sales Agreement. The amount of the Commission shall not exceed 2.0% of the gross sales price for such Offered Shares sold. The Commission will be paid in United States dollars. The sales proceeds remaining after payment of the Commission and after deducting any expenses payable by the Corporation and any transaction or filing fees imposed by any governmental entity or self-regulatory organization in connection with the sales, will equal the net proceeds to the Corporation from the sale of such Offered Shares.

S-9

Settlement for sales of Offered Shares will occur, unless the parties agree otherwise, on the second business day that is also a Trading Day following the date on which any sales were made in return for payment of the gross proceeds to the Corporation, less transaction fees, transfer taxes or similar taxes or fees imposed by any governmental entity or self-regulatory organization in respect of such sales. There is no arrangement for funds to be received in an escrow, trust or similar arrangement. Sales of Offered Shares in the United States will be settled through the facilities of The Depository Trust Company and sales of Offered Shares in Canada will be settled through the facilities of CDS Clearing and Depository Services Inc.

The Corporation will disclose the number and average price of the Offered Shares sold under this prospectus supplement, as well as the gross proceeds, net proceeds received by the Corporation, and the aggregate compensation paid by the Corporation to the Agents in the Corporation’s annual and interim financial statements and related management’s discussion and analysis filed on www.sedar.com and with the SEC, for any fiscal quarters in which sales of Offered Shares occur.

In connection with the sales of the Offered Shares on the Corporation’s behalf, each of the Agents may be deemed to be an “underwriter” within the meaning of the U.S. Securities Act, and the compensation paid to the Agents may be deemed to be underwriting commissions or discounts. The Corporation has agreed in the Sales Agreement to provide indemnification and contribution to the Agents against certain liabilities, including liabilities under the U.S. Securities Act and under Canadian securities laws. In addition, the Corporation has agreed to pay the reasonable expenses of the Agents in connection with the Offering, pursuant to the terms of the Sales Agreement.

As a consequence of their participation in the Offering, the Agents will be entitled to share in the Commission relating to the Offering of the Offered Shares. The Corporation may have outstanding indebtedness owing to certain of the Agents and lending affiliates of such Agents, a portion of which the Corporation may reduce or repay with the net proceeds of the Offering. See “Use of Proceeds” and “Relationship Between the Corporation and Certain of the Agents (Conflicts of Interest)”. As a result, one or more of such Agents or their affiliates may receive more than 5% of the net proceeds from the Offering in the form of the repayment of such indebtedness. Accordingly, the Offering will be conducted in accordance with Rule 5121 of the Financial Industry Regulatory Authority, Inc. (“FINRA”). Pursuant to this rule, the appointment of a qualified independent underwriter is not necessary in connection with the Offering, because the conditions of FINRA Rule 5121(a)(1)(B) are satisfied. To comply with FINRA Rule 5121, each of the Agents will not confirm any sales to any account over which it exercises discretionary authority without the specific written approval of the transaction from the account holder.

The total expenses that the Corporation incurred related to the commencement of the Offering, excluding the Commission payable to the Agents under the terms of the Sales Agreement, was approximately US$900,000.

Pursuant to the Sales Agreement, the Offering will terminate upon the earlier of (i) the issuance and sale of all of the Offered Shares subject to the Sales Agreement, and (ii) the termination of the Sales Agreement as permitted therein.

The Agents and their affiliates may in the future provide various investment banking, commercial banking and other financial services for the Corporation and its affiliates, for which services they may in the future receive customary fees. To the extent required by Regulation M under the Exchange Act, the Agents will not engage in any market making activities involving the Common Shares while the Offering is ongoing under this prospectus supplement.

The Common Shares are listed on the TSX, the NYSE and the LSE. The TSX has conditionally approved the listing of the Offered Shares distributed under the Offering, subject to Wheaton fulfilling all of the requirements of the TSX. The NYSE has authorized the listing of the Offered Shares distributed under the Offering, subject to official notice of issuance. Following the issuance of any Offered Shares, Wheaton will make the required filings and applications to the FCA with respect to the listing of the Offered Shares distributed under the Offering on the standard segment of the FCA’s Official List and to the LSE for admission of the Offered Shares to trading on the Main Market of the LSE.

RELATIONSHIP BETWEEN THE CORPORATION AND CERTAIN OF THE AGENTS (CONFLICTS OF INTEREST)

Certain banking affiliates of Merrill Lynch Canada Inc., BMO Nesbitt Burns Inc., RBC Dominion Securities Inc., Scotia Capital Inc., CIBC World Markets Inc., TD Securities Inc., National Bank Financial Inc., BofA Securities, Inc., BMO Capital Markets Corp., RBC Capital Markets, LLC, Scotia Capital (USA) Inc., MUFG Securities Americas Inc. and Mizuho Securities USA LLC are members of a syndicate of lenders that has provided the US$2 billion revolving credit facility (as amended from time to time, the “Credit Facility”) to the Corporation. As a result, the Corporation may be considered a “connected issuer” to these Agents for purposes of Canadian securities laws.

S-10

The Corporation is not in default of its obligations to the lenders under the Credit Facility and the lenders have not waived any breach of the applicable agreement since it was entered into. As at the date of this prospectus supplement, the Corporation has US$715,500,000 drawn under the Credit Facility. Each of the Corporation’s material subsidiaries (as defined in the Credit Facility agreement) has guaranteed the Corporation’s indebtedness under the Credit Facility. The determination of the terms and conditions of the Offering were made through negotiations among the Agents and the Corporation without the involvement of the lenders, although the lenders have been advised of the Offering. Other than the Commission and agreed upon expenses of the Agents payable to the Agents in connection with the Offering and the potential repayment of indebtedness to one or more of the Agents or their lending affiliates out of the net proceeds of the Offering, the Agents and their affiliates will derive no benefit from the Offering. See “Use of Proceeds” and “Plan of Distribution”.

DESCRIPTION OF COMMON SHARES

The Corporation is authorized to issue an unlimited number of Common Shares. For a description of the terms and provisions of the Common Shares, see “Description of Securities – Common Shares” in the prospectus. As of May 11, 2021, there were 450,058,073 Common Shares outstanding.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

In the opinion of Cassels Brock & Blackwell LLP, Canadian counsel to the Corporation, and Blake, Cassels & Graydon LLP, Canadian counsel to the Agents, the following is a summary of the principal Canadian federal income tax considerations under the Income Tax Act (Canada) (the “Tax Act”) generally applicable to a holder who acquires Offered Shares under the Offering and who, for purposes of the Tax Act and at all relevant times, acquires and holds the Offered Shares as capital property, deals at arm’s length with the Corporation and the Agents, and is not affiliated with the Corporation or the Agents (a “Holder”). Generally, the Offered Shares will be considered to be capital property to a Holder thereof provided that the Holder does not use or hold the Offered Shares in the course of carrying on a business of buying and selling securities and such Holder has not acquired them in one or more transactions considered to be an adventure or concern in the nature of trade.

This summary does not apply to a Holder (i) that is a “financial institution” for purposes of the mark-to-market rules contained in the Tax Act; (ii) that is a “specified financial institution” as defined in the Tax Act; (iii) an interest in which is a “tax shelter investment” as defined in the Tax Act; (iv) that has elected to report its tax results in a “functional currency” (as defined in the Tax Act, which excludes Canadian currency); or (v) that has entered or will enter into, with respect to the Offered Shares, a “derivative forward agreement” or a “synthetic disposition agreement”, as those terms are defined in the Tax Act. Additional considerations, not discussed herein, may be applicable to a Holder that is a corporation resident in Canada (for the purpose of the Tax Act) or a corporation that does not deal at arm’s length (for purposes of the Tax Act) with a corporation resident in Canada, and that is or becomes as part of a transaction or event or series of transactions or events that includes the acquisition of the Offered Shares, controlled by a non-resident person, or group of non-resident persons not dealing with each other at arm’s length for the purposes of the foreign affiliate dumping rules in Section 212.3 of the Tax Act. Such Holders should consult their own tax advisors with respect to an investment in Offered Shares.

This summary is based on the facts set out in this prospectus supplement and the prospectus, the provisions of the Tax Act (and the regulations thereunder (the “Regulations”)) in force as of the date prior to the date hereof and counsel’s understanding of the current administrative policies and assessing practices of the CRA published in writing by the CRA prior to the date hereof. This summary takes into account all specific proposals to amend the Tax Act and the Regulations publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the “Tax Proposals”) and assumes that the Tax Proposals will be enacted in the form proposed, although no assurance can be given that the Tax Proposals will be enacted in their current form or at all. This summary does not otherwise take into account or anticipate any changes in law or in the administrative policies or assessing practices of the CRA, whether by way of judicial, legislative or governmental decision or action. This summary is not exhaustive of all possible Canadian federal income tax considerations, and does not take into account other federal or any provincial, territorial or foreign income tax legislation or considerations, which may differ materially from those described in this summary.

This summary is of a general nature only and is not, and is not intended to be, and should not be construed to be, legal or tax advice to any particular Holder, and no representations concerning the tax consequences to any particular Holder are made. The tax consequences of acquiring, holding and disposing of Offered Shares will vary according to the Holder’s particular circumstances. Holders should consult their own tax advisors regarding the tax considerations applicable to them having regard to their particular circumstances.

Currency Conversion

For purposes of the Tax Act, all amounts must be computed in Canadian dollars using the Bank of Canada rate for the day on which such amount arose or such other rate as is acceptable to the CRA.

S-13

Taxation of Resident Holders

The following portion of the summary applies to a Holder who, for purposes of the Tax Act and any applicable income tax treaty or convention, is or is deemed to be resident in Canada at all relevant times (a “Resident Holder”). A Resident Holder to whom Offered Shares might not constitute capital property may make, in certain circumstances, an irrevocable election permitted by subsection 39(4) of the Tax Act to have the Offered Shares, and all other “Canadian securities” as defined in the Tax Act, held by such Resident Holder in the taxation year of the election and in all subsequent taxation years, treated as capital property. Resident Holders should consult their own tax advisors regarding this election.

Dividends on Offered Shares

Dividends (including deemed dividends) received on the Offered Shares by a Resident Holder who is an individual (other than certain trusts) will be included in the individual’s income and will be subject to the gross-up and dividend tax credit rules applicable to taxable dividends received by individuals from “taxable Canadian corporations”, as defined in the Tax Act, including the enhanced dividend tax credit rules applicable to any dividends designated by the Corporation as “eligible dividends” in accordance with the Tax Act. There may be limits on the ability of the Corporation to designate dividends as eligible dividends.

Dividends (including deemed dividends) received on the Offered Shares by a Resident Holder that is a corporation will be included in computing the corporation’s income and will generally be deductible in computing its taxable income. In certain circumstances, subsection 55(2) of the Tax Act will treat a taxable dividend received by a Resident Holder that is a corporation as proceeds of disposition or a capital gain. Resident Holders that are corporations are urged to consult their own tax advisors having regard to their particular circumstances. A Resident Holder that is a “private corporation” or a “subject corporation”, each as defined in the Tax Act, may be liable to pay a refundable tax under Part IV of the Tax Act on dividends received (or deemed to be received) on the Offered Shares to the extent that such dividends are deductible in computing taxable income.

Disposition of Offered Shares

Generally, upon a disposition (or a deemed disposition) of an Offered Share a Resident Holder will realize a capital gain (or a capital loss) equal to the amount by which the Resident Holder’s proceeds of disposition are greater (or less) than the Resident Holder’s adjusted cost base of such share and any reasonable costs of the disposition. The adjusted cost base to the Resident Holder of an Offered Share acquired pursuant to this Offering will be determined by averaging the cost of such share with the adjusted cost base of all Common Shares of the Corporation owned by the Resident Holder as capital property immediately before the time of acquisition, if any. The tax treatment of capital gains and capital losses is discussed below under “Capital Gains and Capital Losses”.

Capital Gains and Capital Losses

Generally, one-half of any capital gain (a “taxable capital gain”), realized by a Resident Holder in a taxation year must be included in the Resident Holder’s income for that year and one-half of any capital loss (an “allowable capital loss”) realized by a Resident Holder in a taxation year must be deducted against taxable capital gains realized by the Resident Holder in the year. Allowable capital losses in excess of taxable capital gains realized in a particular taxation year generally may be carried back and deducted in any of the three preceding taxation years or carried forward and deducted in any subsequent taxation year against net taxable capital gains realized by the Resident Holder in such years, to the extent and in the circumstances described in the Tax Act.

The amount of any capital loss realized by a Resident Holder that is a corporation on the disposition (or deemed disposition) of an Offered Share may be reduced by the amount of any dividends received (or deemed to be received) by the Resident Holder on such share (or a share substituted for such share) to the extent and under the circumstances described in the Tax Act. Similar rules may apply where an Offered Share is owned by a partnership or trust of which a corporation, trust or partnership is a member or beneficiary.

Other Income Taxes

A Resident Holder that is, throughout the relevant taxation year, a “Canadian-controlled private corporation” (as defined in the Tax Act) may be liable to pay an additional refundable tax on its “aggregate investment income” (as defined in the Tax Act) for the year, including any dividends or deemed dividends that are not deductible in computing the Resident Holder’s taxable income and taxable capital gains.

Generally, a Resident Holder that is an individual (other than certain trusts) that receives or is deemed to have received taxable dividends on the Offered Shares or realizes a capital gain on the disposition or deemed disposition of Offered Shares may be liable for minimum tax under the Tax Act. Resident Holders that are individuals should consult their own tax advisors in this regard.

S-14

Taxation of Non-Resident Holders

This portion of the summary is applicable to a Holder who, at all relevant times, is neither resident in Canada nor deemed to be resident in Canada for purposes of the Tax Act and any applicable income tax treaty or convention, and who does not use or hold, (and is not deemed to use or hold) the Offered Shares in connection with carrying on a business in Canada (a “Non-Resident Holder”).

Special rules, which are not discussed in this summary, may apply to a Non-Resident Holder that is an insurer carrying on business in Canada or that is an “authorized foreign bank” (as defined in the Tax Act). Such Non-Resident Holders should consult their own tax advisors with respect to an investment in Offered Shares.

Dividends on Offered Shares

Dividends paid or credited (or deemed to be paid or credited) to a Non-Resident Holder by the Corporation will be subject to Canadian withholding tax at the rate of 25%, subject to a reduction of such rate under the terms of an applicable income tax treaty or convention. In general, in the case of a Non-Resident Holder who is a resident of the United States for purposes of the Canada-United States Tax Convention (1980), as amended (the “Treaty”), who is the beneficial owner of the dividend, and who qualifies for full benefits of the Treaty, the rate of such withholding tax will be reduced to 15% (or 5% if the beneficial owner of such dividend is a company that owns at least 10% of the voting stock of the Corporation). Non-Resident Holders are urged to consult their own advisors to determine their entitlement to relief under an applicable income tax treaty or convention.

Disposition of Offered Shares

A Non-Resident Holder generally will not be subject to tax under the Tax Act in respect of a capital gain realized on the disposition or deemed disposition of an Offered Share unless the Offered Share constitutes (or is deemed to constitute) “taxable Canadian property” of such Non-Resident Holder for purposes of the Tax Act and the gain is not exempt from tax pursuant to the terms of an applicable income tax treaty or convention.

Provided the Offered Shares are listed on a “designated stock exchange” as defined in the Tax Act (which currently includes the TSX, LSE and NYSE) at the time of disposition, the Offered Shares generally will not constitute taxable Canadian property of a Non-Resident Holder unless, at any time during the 60-month period immediately preceding the disposition, (i) 25% or more of the issued shares of any class or series of the capital stock of the Corporation were owned by or belonged to any combination of (a) the Non-Resident Holder, (b) persons with whom the Non-Resident Holder did not deal at arm’s length, and (c) partnerships in which the Non-Resident Holder or a person described in (b) holds a membership interest directly or indirectly through one or more partnerships; and (ii) more than 50% of the fair market value of such shares was derived, directly or indirectly, from any combination of real or immovable property situated in Canada, “Canadian resource property” (as defined in the Tax Act), “timber resource property” (as defined in the Tax Act), or options in respect of, interests in, or for civil law rights in such properties, whether or not such property exists. Notwithstanding the foregoing, Offered Shares may be deemed to be taxable Canadian property in certain circumstances specified in the Tax Act.

If the Offered Shares are taxable Canadian property (or deemed to be taxable Canadian property) of a Non-Resident Holder, any capital gain realized on the disposition or deemed disposition of such Offered Shares may not be subject to tax under the Tax Act pursuant to the terms of an applicable income tax treaty or convention. If the Offered Shares are taxable Canadian property of a Non-‎Resident Holder and are not “treaty-protected property”, as defined in the Tax Act, of the Non-Resident Holder at the time of ‎disposition (or deemed disposition), the consequences above under “Taxation of Resident Holders - Disposition of Offered Shares‎‎” and “Taxation of Resident Holders - Capital Gains and Capital Losses‎‎” will generally apply.

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

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a general summary of certain anticipated material U.S. federal income tax considerations applicable to a U.S. Holder (as defined below) arising from and relating to the acquisition, ownership and disposition of Common Shares acquired pursuant to the Offering.

This summary is for general information purposes only and does not purport to be a complete analysis of all potential U.S. federal income tax consequences that may apply to a U.S. Holder arising from and relating to the acquisition, ownership and disposition of Common Shares. This summary only applies to “U.S. Holders” that hold the Common Shares as “capital assets” within the meaning of Section 1221 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”) (generally, property held for investment) and that do not own and are not treated as owning (directly, indirectly, or by attribution) 10% or more of the total combined voting power or value of all outstanding shares of the Corporation. In addition, this summary does not take into account the individual facts and

S-15

circumstances of any particular U.S. Holder that may affect the U.S. federal income tax consequences to such U.S. Holder, including specific tax consequences to a U.S. Holder under an applicable tax treaty. This summary does not address estate or gift, any U.S. federal tax consequences other than income, or any U.S. state and local, or non-U.S. tax consequences to U.S. Holders of the acquisition, ownership and disposition of Common Shares. Each U.S. Holder of Common Shares is urged to consult its own tax advisor regarding the U.S. federal income, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and non-U.S. tax consequences relating to the acquisition, ownership and disposition of Common Shares.

The Corporation has not requested, and will not request, a ruling from the U.S. Internal Revenue Service (the “IRS”) regarding the U.S. federal income tax consequences of the acquisition, 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 conclusions described in this summary.

The following discussion is not intended to be, nor should it be construed as, legal or tax advice to any holder or prospective holder of Common Shares and no opinion or representation with respect to the U.S. federal income tax consequences to any such holder or prospective holder is made.

This summary is based on the Code, U.S. Treasury Regulations (whether final, temporary, or proposed) (“Treasury Regulations”), published administrative positions of the IRS, the Treaty, and U.S. court decisions that are applicable and, in each case, as in effect and available as of the date of this Prospectus Supplement. 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 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 basis.

This summary does not address the U.S. federal income tax consequences of the acquisition, ownership and disposition of Common Shares to U.S. Holders that are subject to special provisions under the Code, including, but not limited to, the U.S. Holders that: (a) are tax-exempt entities; (b) are banks, financial institutions, insurance companies, real estate investment trusts, or regulated investment companies; (c) are partnerships or their partners; (d) are dealers or traders in securities or currencies; (e) are traders in securities that elect to apply a mark-to-market accounting method; (f) have a “functional currency” other than the U.S. dollar; (g) own Common Shares as part of a straddle, hedging transaction, conversion transaction, constructive sale, or other integrated security transaction for U.S. federal income tax purposes; (h) acquired Common Shares in connection with the exercise or cancellation of employee stock options or otherwise as compensation for services; (i) are U.S. expatriates; (j) are subject to the alternative minimum tax; or (k) are required to accelerate the recognition of any item of gross income as a result of such income being recognized on an applicable financial statement. U.S. Holders that are subject to special provisions under the Code, including, but not limited to, U.S. Holders described immediately above, are urged to consult their own tax advisors regarding the U.S. federal income, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and non-U.S. tax consequences relating to the acquisition, ownership and disposition of Common Shares.

For purposes of this summary, the term “U.S. Holder” means a beneficial owner of Common Shares that is: (i) an individual who is a citizen or resident of the United States as determined for U.S. federal income tax purposes, (ii) a corporation, or other entity treated as a corporation for U.S. federal income tax purposes, created in or organized under the law of the United States, any State thereof, or the District of Columbia, (iii) an estate the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source, or (iv) a trust (A) the administration of which is subject to the primary supervision of a U.S. court and which has one or more U.S. persons who have the authority to control all substantial decisions of the trust, or (B) that has validly elected to be subject to tax as a U.S. person under the Code and applicable Treasury Regulations.

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

Ownership and Disposition of Common Shares

The following discussion is subject to the rules described below under the heading “Passive Foreign Investment Company Rules.”

S-16

Distributions on Common Shares

A U.S. Holder that receives a distribution with respect to a Common Share will be required to include the amount of such distribution in gross income as a dividend (without reduction for the amount of any Canadian income tax withheld from such distribution) to the extent of the current or accumulated “earnings and profits” of the Corporation, as calculated for U.S. federal income tax purposes. Such amount will be includable in gross income by a U.S. Holder as ordinary income on the date that the U.S. Holder actually or constructively receives the distribution in accordance with its regular method of accounting for U.S. federal income tax purposes. The amount of any distribution made by the Corporation in property other than cash will be the fair market value of such property on the date of the distribution. See “Foreign Tax Credits” below for a discussion of the availability of any foreign tax credits related to Canadian taxes withheld.

To the extent that a distribution exceeds the current and accumulated “earnings and profits” of the Corporation, such distribution will be treated first as a tax-free return of capital to the extent of a U.S. Holder’s adjusted tax basis in the Common Shares, causing a reduction in the U.S. Holder’s adjusted tax basis in the Common Shares held by such U.S. Holder (thereby increasing the amount of gain, or decreasing amount of loss, to be recognized by such U.S. Holder upon a subsequent disposition of such Common Shares), with any amount that exceeds the adjusted tax basis being treated as a capital gain recognized on a sale, exchange or other taxable disposition of such Common Shares. See “Sale, Exchange or Other Taxable Disposition of Common Shares” below. However, the Corporation does not intend to maintain calculations of its 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 Corporation with respect to Common Shares will be treated as a dividend for U.S. federal income tax purposes. In the case of a U.S. Holder that is a corporation, dividends paid on the common shares generally will not be eligible for the “dividends received deduction.” The dividend rules are complex, and each U.S. Holder are urged to consult its own tax advisor regarding the application of such rules.

Subject to applicable exceptions with respect to short-term and hedged positions, dividends received by non-corporate U.S. Holders from a “qualified foreign corporation” will be eligible for reduced rates of taxation. A qualified foreign corporation includes a foreign corporation that is eligible for the benefits of a comprehensive income tax treaty with the United States that the U.S. Treasury Department determines to be satisfactory for these purposes and that includes an exchange of information provision. The U.S. Treasury Department has determined that the Treaty meets these requirements, and the Corporation believes that it is eligible for the benefits of the Treaty. A foreign corporation is also treated as a qualified foreign corporation with respect to dividends paid by that corporation on ordinary shares that are readily tradeable on an established securities market in the United States. U.S. Treasury Department guidance indicates that the Common Shares are readily tradeable on an established securities market in the United States. However, there can be no assurance that the Common Shares will be considered readily tradeable on an established securities market in the United States in future years. If the Corporation is classified as a PFIC (as defined below) in the taxable year of distribution or in the preceding taxable year, then dividends received by U.S. Holders will not be qualified dividends. As discussed below in “Passive Foreign Investment Company Rules,” although not free from doubt, the Corporation believes that it is not currently a PFIC and believes it was not a PFIC for its prior taxable year.

Sale, Exchange or Other Taxable Disposition of Common Shares

A U.S. Holder generally will recognize gain or loss upon the sale, exchange or other taxable disposition of Common Shares in an amount equal to the difference between (i) the amount realized upon the sale, exchange or other taxable disposition and (ii) such U.S. Holder’s adjusted tax basis in Common Shares. Such gain or loss will generally be capital gain or loss and will be long-term capital gain or loss if, on the date of the sale, exchange or other taxable disposition, the U.S. Holder has held the Common Shares for more than one year. Certain non-corporate U.S. Holders (including individuals) may qualify for preferential rates of U.S. federal income taxation in respect of long-term capital gains. The deductibility of capital losses is subject to limitations. Gain or loss, if any, that is realized upon a sale, exchange or other taxable disposition of Common Shares generally will be treated as income from sources within the United States for U.S. foreign tax credit limitation purposes.

Passive Foreign Investment Company Rules

Special, generally unfavourable, U.S. federal income tax rules apply to U.S. persons owning stock of a Passive Foreign Investment Company (“PFIC”). A foreign corporation will be considered a PFIC for any taxable year in which, after taking into account the income and assets of the corporation and certain subsidiaries pursuant to applicable “look through” rules, either (1) at least 75 percent of its gross income is “passive” income (the “income test”) or (2) at least 50 percent of the average value of its assets is attributable to assets that produce passive income or are held for the production of passive income (the “asset test”). For this purpose, passive income generally includes, among other things, dividends, interest, certain rents and royalties, gains from the disposition of passive assets and certain net gains from commodities transactions. For purposes of determining whether a foreign corporation will be considered a PFIC, such foreign corporation will be treated as holding its proportionate share of the assets and receiving directly its proportionate share of the income of any other corporation in which it owns, directly or indirectly, at least 25 percent (by value) of the stock. PFIC status is fundamentally factual in nature. It generally cannot be determined until the close of the taxable year in question and is determined annually.

S-17

Under certain attribution rules, if the Corporation were a PFIC, U.S. Holders would generally be deemed to own their proportionate share of the Corporation’s direct or indirect equity interest in any company that is also a PFIC (a “Subsidiary PFIC”), and would be subject to U.S. federal income tax on any indirect gain realized on the stock of a Subsidiary PFIC upon the sale of the Common Shares of the Corporation, as well as their proportionate share of (a) any “excess distributions” (as discussed below) on the stock of a Subsidiary PFIC and (b) any gain realized upon the disposition or deemed disposition of stock of a Subsidiary PFIC by the Corporation or by another Subsidiary PFIC, both as if such U.S. Holders directly held the shares of such Subsidiary PFIC.

Although not free from doubt, the Corporation believes that it currently is not a PFIC and does not expect to be classified as a PFIC in the foreseeable future for U.S. federal income tax purposes. However, the determination of PFIC status for any year is very fact specific, being based on the types of income the Corporation earns and the types and value of the Corporation’s assets from time to time, all of which are subject to change, as well as, in part, the application of complex U.S. federal income tax rules, which are subject to differing interpretations. As a result, there can be no assurance in this regard, and the IRS may challenge the Corporation’s classification. Accordingly, it is possible that the Corporation may be classified as a PFIC in the current taxable year or in future years. If the Corporation is classified as a PFIC in any year during which a U.S. Holder holds Common Shares, the Corporation generally will continue to be treated as a PFIC as to such U.S. Holder in all succeeding years unless a U.S. Holder makes certain elections, for such year and all succeeding years during which such U.S. Holder holds Common Shares, regardless of whether the Corporation continues to meet the income or asset test discussed above.

If the Corporation were classified as a PFIC for any taxable year during which a U.S. Holder holds Common Shares, such U.S. Holder would be subject to increased tax liability (generally including an interest charge) upon the sale or other disposition of Common Shares or upon the receipt of certain distributions treated as “excess distributions”, regardless of whether such income was actually distributed. An excess distribution generally would be the portion of any distributions to a U.S. Holder with respect to Common Shares during a single taxable year that are in total greater than 125% of the average annual distributions received by such U.S. Holder with respect to Common Shares during the three preceding taxable years or, if shorter, during such U.S. Holder’s holding period for such Common Shares. Generally, a U.S. Holder would be required to allocate any excess distribution or gain from the sale or other disposition of the Common Shares ratably over its holding period for Common Shares. Such amounts would be taxed as ordinary income at the highest applicable rate in effect for each taxable year of the holding period, and amounts allocated to prior taxable years would be subject to an interest charge at a rate applicable to underpayments of tax.

If the Corporation is classified as a PFIC, certain elections could be available to mitigate such consequences. If the Common Shares are regularly traded on a registered national securities exchange or certain other exchanges or markets, then such Common Shares will constitute “marketable stock” for purposes of the PFIC rules. The Corporation expects that the Common Shares will constitute “marketable stock” for purposes of the PFIC rules. U.S. Holders that make a “mark-to-market election” with respect to such marketable stock would not be subject to the foregoing PFIC rules. After making such an election, a U.S. Holder generally would include as ordinary income each year during which the election is in effect and during which the Corporation is a PFIC the excess, if any, of the fair market value of Common Shares at the end of the taxable year over the U.S. Holder’s adjusted tax basis in such Common Shares. These amounts of ordinary income would not be eligible for the favorable tax rates applicable to qualified dividend income or long-term capital gains. A U.S. Holder with a mark-to-market election in effect also would be allowed to take an ordinary loss in respect of the excess, if any, of its adjusted tax basis in Common Shares over their fair market value at the end of the taxable year (but only to the extent of the net amount of income that was previously included as a result of the mark-to-market election). A U.S. Holder’s tax basis in Common Shares would be adjusted to reflect any income or loss amounts resulting from a mark-to-market election. If made, a mark-to-market election would be effective for the taxable year for which the election was made and for all subsequent taxable years unless the Common Shares ceased to qualify as “marketable stock” for purposes of the PFIC rules or the IRS consented to the revocation of the election. However, the mark-to-market election will not be available with respect to any Subsidiary PFIC. Accordingly, U.S. Holders making a mark-to-market election would be subject to unfavorable tax consequences described above with respect to any Subsidiary PFIC. In the event that the Corporation is classified as a PFIC, U.S. Holders are urged to consult their own tax advisor regarding the availability of the mark-to-market election, and whether the election would be advisable in their particular circumstances.

The PFIC tax rules outlined above also would not apply to a U.S. Holder that elected to treat the Corporation as a “qualified electing fund” (a “QEF”). An election to treat the Corporation as a QEF will not be available, however, if the Corporation does not provide the information necessary to make such an election. The Corporation does not intend to provide the information necessary to make a QEF election, and thus, a QEF election will not be available with respect to Common Shares.

As discussed above in “Distributions on Common Shares”, notwithstanding any election made with respect to the Common Shares, if the Corporation is a PFIC in either the taxable year of the distribution or the preceding taxable year, dividends received with respect to Common Shares will not qualify for reduced rates of taxation.

Additional Considerations

Tax on Passive Income

U.S. Holders that are individuals, estates and trusts are required to pay a 3.8 percent additional tax on the lesser of (1) the U.S. Holder’s “net investment income” for the relevant taxable year and (2) the excess of the U.S. Holder’s modified adjusted gross income for the taxable year over a certain threshold. A U.S. Holder’s “net investment income” generally includes, among other things, dividends and net gains from disposition of property (other than property held in the ordinary course of the conduct of a trade or business). Accordingly, dividends on and capital gain from the sale or other taxable disposition of the Common Shares may be subject to this additional tax. U.S. Holders are urged to consult their own tax advisors regarding the additional tax on passive income.

Receipt of Foreign Currency

The gross amount of any payment in a currency other than U.S. dollars will be included by each U.S. Holder in income in a U.S. dollar amount calculated by reference to the exchange rate in effect on the day such U.S. Holder actually or constructively receives the payment in accordance with its regular method of accounting for U.S. federal income tax purposes regardless of whether the payment is in fact converted into U.S. dollars at that time. If the foreign currency is converted into U.S. dollars on the date of the payment, the U.S. Holder should not be required to recognize any foreign currency gain or loss with respect to the receipt of foreign currency. If, instead, the foreign currency is converted at a later date, any currency gains or losses resulting from the conversion of the foreign currency will be treated as U.S. source ordinary income or loss. U.S. Holders are urged to 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 Credits

In general, any Canadian income tax imposed on dividend payments (whether directly or through withholding) in respect of Common Shares will be treated as a foreign income tax eligible for credit against a U.S. Holder’s U.S. federal income tax liability (or, at a U.S. Holder’s election, may, in certain circumstances, be deducted in computing taxable income). Dividends paid on 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. The Code applies various complex limitations on the amount of foreign taxes that may be claimed as a credit by U.S. taxpayers. Accordingly, U.S. Holders are urged to consult their own tax advisors regarding the availability of the foreign tax credit under their particular circumstances.

Disclosure Requirements for Specified Foreign Financial Assets

Certain U.S. Holders that, during any taxable year, hold an interest in “specified foreign financial assets” with an aggregate value in excess of US$50,000 (and in some circumstances, a higher threshold), may be required to file an information report with respect to such assets with their tax returns. “Specified foreign financial assets” generally include any financial accounts maintained by foreign financial institutions, as well as any of the following, but only if they are not held in accounts maintained by financial institutions: (i) stocks and securities issued by non-U.S. persons, (ii) financial instruments and contracts held for investment that have non-U.S. issuers or counterparties and (iii) interests in foreign entities. U.S. Holders are urged to consult their own tax advisors regarding the application of the information reporting rules to the Common Shares and their particular situations.

Backup Withholding and Additional Information Reporting

In general, dividends paid to a U.S. Holder in respect of Common Shares and the proceeds received by a U.S. Holder from the sale, exchange or other disposition of Common Shares within the United States or through certain U.S.-related financial intermediaries will be subject to U.S. information reporting rules, unless a U.S. Holder is a corporation or other exempt recipient and properly establishes such exemption. Backup withholding may apply to such payments if a U.S. Holder does not establish an exemption from backup withholding and fails to provide a correct taxpayer identification number and make any other required certifications.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or credit against U.S. federal income tax liability, provided that the required information is timely furnished to the IRS. Each U.S. Holder is urged to consult its own tax advisor regarding the information reporting and backup withholding rules.

ENFORCEABILITY OF CERTAIN CIVIL LIABILITIES

The Corporation is an Ontario corporation and its principal place of business is in Canada. The majority of the directors and officers of the Corporation are resident outside of the United States and a substantial portion of its assets and the assets of such persons are located outside of the United States. Consequently, it may be difficult for United States investors to effect service of process within the United States on the Corporation or its directors or officers, or to realize in the United States on judgments of courts of the United States predicated on civil liabilities under the U.S. Securities Act. Investors should not assume that Canadian courts would enforce judgments of United States courts obtained in actions against the Corporation or such persons predicated on the civil liability provisions of the United States federal securities laws or the securities or “blue sky” laws of any state within the United States or would enforce, in original actions, liabilities against the Corporation or such persons predicated on the United States federal securities or any such state securities or “blue sky” laws. The Corporation has been advised by its Canadian counsel, Cassels Brock & Blackwell 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. The Corporation cannot provide assurance that this will be the case. It is less certain that an action could be brought in Canada in the first instance on the basis of liability predicated solely upon such laws.

The Corporation filed with the SEC, concurrently with the Registration Statement on Form F-10 of which this prospectus supplement is a part, an appointment of agent for service of process on Form F-X. Under the Form F-X, the Corporation appointed Puglisi & Associates as its 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 the Corporation in a United States court, arising out of or related to or concerning the offering of securities under this prospectus supplement.

Wheaton Precious Metals Corp. (“Wheaton” or the “Corporation”) may offer and sell from time to time common shares (the “Common Shares”), preferred shares (the “Preferred Shares”), debt securities (the “Debt Securities”), subscription receipts (the “Subscription Receipts”), units (the “Units”) and warrants (the “Warrants”) (all of the foregoing, collectively, the “Securities”) or any combination thereof in one or more series or issuances up to an aggregate total offering price of US$2,000,000,000 (or the equivalent thereof in other currencies) during the 25 month period that this short form base shelf prospectus (the “Prospectus”), including any amendments thereto, remains effective. The Securities may be offered separately or together or in any combination, and as separate series, in amounts, at prices and on terms to be determined based on market conditions at the time of sale and set forth in an accompanying shelf prospectus supplement (a “Prospectus Supplement”). This Prospectus may qualify an “at-the-market distribution”, as defined in National Instrument 44-102 – Shelf Distributions (“NI 44-102”).

Wheaton is permitted, under a multijurisdictional disclosure system adopted by the securities regulatory authorities in Canada and the United States, to prepare this Prospectus in accordance with Canadian disclosure requirements. Prospective investors in the United States should be aware that such requirements are different from those of the United States. Wheaton prepares its financial statements, which are incorporated by reference herein, in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”) and thus may not be comparable to financial statements of United States companies.

The enforcement by investors of civil liabilities under the United States federal securities laws may be affected adversely by the fact that the Corporation is incorporated under the laws of Ontario, Canada, that some or all of its officers and directors may be residents of a foreign country, that some or all of the experts named in this Prospectus may be, and the underwriters, dealers or agents named in any Prospectus Supplement may be, residents of a foreign country, and a substantial portion of the assets of the Corporation and said persons may be located outside of the United States. See “Enforceability of Certain Civil Liabilities”.

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

Prospective investors should be aware that the acquisition of the Securities may have tax consequences in

Canada and the United States. Such consequences may not be described fully herein or in any applicable Prospectus Supplement. Prospective investors should read the tax discussion contained in this Prospectus under the heading “Certain Federal Income Tax Considerations” as well as the tax discussion contained in the applicable Prospectus Supplement with respect to a particular offering of Securities.

Wheaton will provide the specific terms of any offering of Securities, including the specific terms of the Securities with respect to a particular offering and the terms of such offering, in one or more Prospectus Supplements. All applicable information permitted under applicable laws to be omitted from this Prospectus that has been omitted will be contained in one or more Prospectus Supplements that will be delivered to purchasers together with this Prospectus, except in cases where an exemption from such delivery requirements is available. Each Prospectus Supplement will be incorporated by reference into this Prospectus for the purposes of securities legislation 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. Prospective investors should read this Prospectus and any applicable Prospectus Supplement carefully before investing in any Securities issued pursuant to this Prospectus.

No underwriter has been involved in the preparation of this Prospectus or performed any review of the contents of this Prospectus.

This Prospectus constitutes a public offering of these Securities only in those jurisdictions where they may be lawfully offered for sale and therein only by persons permitted to sell such Securities. The Corporation may offer and sell Securities to, or through, underwriters or dealers and may also offer and sell certain Securities directly to other purchasers or through agents pursuant to exemptions from registration or qualification under applicable securities laws. A Prospectus Supplement relating to each issue of Securities offered pursuant to this Prospectus will set forth the names of any underwriters, dealers or agents involved in the offering and sale of such Securities and will set forth the terms of the offering of such Securities, the method of distribution of such Securities including, to the extent applicable, the proceeds to the Corporation, if any, and any fees, discounts or any other compensation payable to underwriters, dealers or agents and any other material terms of the plan of distribution.

In connection with any offering of Securities, except as otherwise set out in a Prospectus Supplement relating to a particular offering of Securities, the underwriters or dealers may over-allot or effect transactions which stabilize or maintain the market price of the Securities offered at a level above that which might otherwise prevail in the open market. Such transactions, if commenced, may be discontinued at any time. No underwriter of the at-the-market distribution, and no person or company acting jointly or in concert with an underwriter, 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 “at-the-market” prospectus, including selling an aggregate number or principal amount of Securities that would result in the underwriter creating an over-allocation position in the Securities. See “Plan of Distribution”.

The outstanding Common Shares are listed and posted for trading on the Toronto Stock Exchange (the “TSX”), listed on the New York Stock Exchange (the “NYSE”) and admitted to trading on the London Stock Exchange (“LSE”), in each case under the trading symbol “WPM”. On April 21, 2021, the last trading day prior to the date of this Prospectus, the closing price of the Common Shares on the TSX was C$54.24, on the NYSE was US$43.41 and on the LSE was £31.30. Unless otherwise specified in the applicable Prospectus Supplement, the Preferred Shares, Debt Securities, Subscription Receipts, Units and Warrants will not be listed on any securities exchange. Consequently, unless otherwise specified in the applicable Prospectus Supplement, there is no market through which such Securities may be sold and purchasers may not be able to resell any such Securities purchased under this Prospectus. This may affect the pricing of such Securities in the secondary market, the transparency and availability of trading prices, the liquidity of such Securities and the extent of issuer regulation.

-xxii-

(as defined herein), resides outside of Canada. Prospective investors are advised that it may not be possible for investors to enforce judgments obtained in Canada against any person or company that is incorporated, continued or otherwise organized under the laws of a foreign jurisdiction or resides outside of Canada, even if the party has appointed an agent for service of process.

Investing in the Securities involves significant risks. The risks outlined in this Prospectus and in the documents incorporated by reference herein, including the applicable Prospectus Supplement, should be carefully reviewed and considered by prospective investors in connection with any investment in Securities. See “Cautionary Note Regarding Forward-Looking Statements and Information” and “Risk Factors”.

Wheaton has filed an undertaking with each of the securities regulatory authorities in each of the provinces and territories of Canada that it will not distribute Securities that, at the time of distribution, are novel specified derivatives or novel asset-backed securities, without first pre-clearing with the applicable regulator, the disclosure to be contained in the Prospectus Supplement pertaining to the distribution of such Securities.

All dollar amounts in this Prospectus are in United States dollars, unless otherwise indicated. See “Currency Presentation and Exchange Rate Information”. Where required by statute, regulation or policy, and where Securities are offered in currencies other than Canadian dollars, appropriate disclosure of foreign exchange rates applicable to such Securities will be included in the Prospectus Supplement describing such Securities.
