Description of Business and Nature of Operations	1. Description of Business and Nature of Operations Wheaton Precious Metals Corp. is a precious metal streaming company which generates its revenue primarily from the sale of precious metals (gold, silver and palladium) and cobalt. Wheaton Precious Metals Corp. (“Wheaton” or the “Company”), which is the ultimate parent company of its consolidated group, is incorporated and domiciled in Canada, and its principal place of business is at Suite 3500 - 1021 West Hastings Street, Vancouver, British Columbia, V6E 0C3. The Company trades on the Toronto Stock Exchange (“TSX”), the New York Stock Exchange (“NYSE”) and the London Stock Exchange (“LSE”) under the symbol WPM. As of June 30, 2021, the Company has entered into 26 long-term purchase agreements (three of which are early deposit agreements), with 19 different mining companies, for the purchase of precious metals and cobalt (“precious metal purchase agreements” or “PMPA”) relating to 24 mining assets which are currently operating, 8 which are at various stages of development and 1 which has been placed in care and maintenance, located in 12 countries. Pursuant to the PMPAs, 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 condensed interim consolidated financial statements of the Company for the three and six months ended June 30, 2021 were authorized for issue as of August 12, 2021 in accordance with a resolution of the Board of Directors. Business Continuity and Employee Health and Safety In accordance with local government restrictions and guidelines, Wheaton temporarily closed its physical offices in mid-March re-opened Partner Operations During the second quarter of 2020, six partner operations located in Mexico and Peru on which the Company has PMPAs were temporarily suspended due to government restrictions focused on reducing the impacts of the COVID-19 COVID-19

Basis of Presentation and Statement of Compliance	2. Basis of Presentation and Statement of Compliance These unaudited condensed interim consolidated financial statements have been prepared on a historical cost basis, except for certain financial instruments which have been measured at fair value as at the relevant balance sheet date. The consolidated financial statements are presented in United States (“US”) dollars, which is the Company’s functional currency, and all values are rounded to the nearest thousand US dollars (US$ 000’s) unless otherwise noted. References to “Cdn$” refer to Canadian dollars. These unaudited condensed interim consolidated financial statements have been prepared in accordance with IAS 34, Interim Financial Reporting (“IAS 34”) as issued by the International Accounting Standards Board. The accounting policies applied in these unaudited condensed interim consolidated financial statements are based on International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) and have been prepared using the same accounting policies and methods of application as disclosed in Note 3 to the audited consolidated financial statements for the year ended December 31, 2020 and were consistently applied to all the periods presented unless otherwise stated below. These unaudited condensed interim consolidated financial statements do not include all the information and note disclosures required by IFRS for annual consolidated financial statements and therefore should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2020. The preparation of financial statements in accordance with IAS 34 requires the use of certain accounting estimates. It also requires management to exercise judgment in applying the Company’s accounting policies. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the financial statements, are disclosed in Note 4. In the opinion of management, all adjustments (including normal recurring adjustments) necessary to present fairly the financial position at June 30, 2021 and the results of operations and cash flows for all periods presented have been made. The interim results are not necessarily indicative of results for a full year.

Significant Accounting Policies	3. Significant Accounting Policies 3.1. Future Changes to Accounting Policies The IASB has issued the following new or amended standards: Amendment to IAS 16 - Property, Plant and Equipment The amendments to IAS 16 prohibit deducting from the cost of property, plant and equipment the proceeds from selling items produced while bringing the assets to the location and condition necessary for them to be capable of operating in the manner intended by management. Instead, a company will recognize such sales proceeds and related cost in the Statement of Earnings. This amendment is in effect January 1, 2022 with early adoption permitted. The adoption of this guidance is not expected to have a material impact on the Company’s Consolidated Statement of Earnings. Amendment to IAS 12 - Deferred Tax related to Assets and Liabilities arising from a Single Transaction The amendments to IAS 12 clarify that the initial recognition exemption does not apply to transactions in which equal amounts of deductible and taxable temporary differences arise on initial recognition. The amendments are effective for annual reporting periods beginning on or after January 1, 2023. Early application of the amendments is permitted. The amendments apply to transactions that occur on or after the beginning of the earliest comparative period presented. In addition, at the beginning of the earliest comparative period the following would be recognized: ● a deferred tax asset to the extent that it is probable that taxable profit will be available against which the deductible temporary difference can be utilised and a deferred tax liability for all deductible and taxable temporary differences associated with right-of-use ● the cumulative effect of initially applying the amendments as an adjustment to the opening balance of retained earnings (or other component of equity, as appropriate) at that date. The Company is currently evaluating the impact of this amendment.

Key Sources of Estimation Uncertainty and Critical Accounting Judgments	4. Key Sources of Estimation Uncertainty and Critical Accounting Judgments The preparation of the Company’s condensed interim consolidated financial statements requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities and contingent liabilities at the date of the consolidated financial statements and reported amounts of revenues and expenses during the reporting period. Estimates and assumptions are continuously evaluated and are based on management’s experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. However, actual outcomes can differ from these estimates. Information about significant areas of estimation uncertainty and judgments made by management in preparing the consolidated financial statements are described below. Key Sources of Estimation Uncertainty 4.1. Attributable Reserve, Resource and Exploration Potential Estimates Mineral stream interests are significant assets of the Company, with a carrying value of $5.6 billion at June 30, 2021. This amount represents the capitalized expenditures related to the acquisition of the mineral stream interests, net of accumulated depletion and accumulated impairment charges, if any. The Company estimates the reserves, resources and exploration potential relating to each agreement. Reserves are estimates of the amount of metals contained in ore that can be economically and legally extracted from the mining properties in respect of which the Company has PMPAs. Resources are estimates of the amount of metals contained in mineralized material for which there is a reasonable prospect for economic extraction from the mining properties in respect of which the Company has PMPAs. Exploration potential represents an estimate of additional reserves and resources which may be discovered through the mine operator’s exploration program. The Company adjusts its estimates of reserves, resources (where applicable) and exploration potential (where applicable) to reflect the Company’s percentage entitlement to metals produced from such mines. The Company compiles its estimates of its reserves and resources based on information supplied by appropriately qualified persons relating to the geological data on the size, density and grade of the ore body, and require complex geological and geostatistical judgments to interpret the data. The estimation of recoverable reserves and resources is based upon factors such as estimates of foreign exchange rates, commodity prices, future capital requirements, and production costs along with geological assumptions and judgments made in estimating the size and grade of the ore body. The Company estimates exploration potential based on assumptions surrounding the ore body continuity which requires judgment as to future success of any exploration programs undertaken by the mine operator. Changes in the reserve estimates, resource estimates or exploration potential estimates may impact upon the carrying value of the Company’s mineral stream interests and depletion charges. 4.2. Depletion The Company’s mineral stream interests are separately allocated to reserves, resources and exploration potential. The value allocated to reserves is classified as depletable and is depleted on a unit-of-production non-depletable 4.3. Impairment of Assets The Company assesses each PMPA at the end of every reporting period to determine whether any indication of impairment or impairment reversal exists. If such an indication exists, the recoverable amount of the PMPA is estimated in order to determine the extent of the impairment or impairment reversal (if any). The calculation of the recoverable amount requires the use of estimates and assumptions such as long-term commodity prices, discount rates, recoverable ounces of attributable metals, and operating performance. The price of precious metals and cobalt has been volatile over the past several years. The Company monitors spot and forward metal prices and if necessary re-evaluates re-evaluate 4.4. Valuation of Stock Based Compensation The Company has various forms of stock based compensation, including share purchase options, restricted share units (“RSUs”) and performance share units (“PSUs”). The calculation of the fair value of share purchase options, RSUs and PSUs issued requires the use of estimates as more fully described in Notes 18.2, 18.3, and 19.1, respectively. 4.5. Contingencies Due to the size, complexity and nature of the Company’s operations, various legal and tax matters are outstanding from time to time, including those matters described in Note 25. By their nature, contingencies will only be resolved when one or more future events occur or fail to occur. The assessment of contingencies inherently involves the exercise of significant judgment and estimates of the outcome of future events. If the Company is unable to resolve any of these matters favorably, there may be a material adverse impact on the Company’s financial performance, cash flows or results of operations. In the event that management’s estimate of the future resolution of these matters changes, the Company will recognize the effects of the changes in its consolidated financial statements in the appropriate period relative to when such changes occur. Critical Accounting Judgments 4.6. Functional Currency The functional currency for the Company and each of its subsidiaries is the currency of the primary economic environment in which the entity operates. As a result of the following factors, the Company has determined that the functional currency of each entity is the US dollar: ● The entities’ revenues are denominated in US dollars; ● The entities’ cash cost of sales are denominated in US dollars; ● The majority of the entities’ cash is held in US dollars; and ● The Company generally seeks to raise capital in US dollars. Determination of the functional currency may involve certain judgments to determine the primary economic environment and the Company reconsiders the functional currency of its entities if there is a change in events and conditions which determined the primary economic environment. 4.7. Income Taxes The interpretation and application of existing tax laws, regulations or rules in Canada, the Cayman Islands, Barbados, Luxembourg, the Netherlands or any of the countries in which the Company’s subsidiaries or the mining operations are located or to which deliveries of precious metals, precious metal credits or cobalt are made requires the use of judgment. The likelihood that tax positions taken will be sustained is assessed based on facts and circumstances of the relevant tax position considering all available evidence. Differing interpretation of these laws, regulations or rules could result in an increase in the Company’s taxes, or other governmental charges, duties or impositions. Refer to Note 25 for more information. In assessing the probability of realizing deferred income tax assets, the Company makes estimates related to expectations of future taxable income, including the expected timing of reversals of existing temporary differences. Such estimates are based on forecasted cash flows from operations which require the use of estimates and assumptions such as long-term commodity prices and recoverable metal ounces. The amount of deferred income tax assets recognized on the balance sheet could be reduced if the actual taxable income differs significantly from expected taxable income. The Company reassesses its deferred income tax assets at the end of each reporting period. 4.8. Leases The Company assesses whether a contract contains a lease and, if so, recognizes a lease liability by discounting the future lease payments by using the Company’s estimated incremental borrowing rate. If the lease agreement contains an option to extend the lease, the Company must assess the likelihood of whether that option will be exercised. The determination of whether an option to extend a lease will be exercised requires significant management judgment, and providing the Company concludes that it is reasonably certain that the option to extend will be exercised, the lease payments during the extension period will comprise part of the right-of-use

Financial Instruments	5. Financial Instruments 5.1. Capital Risk Management The Company manages its capital to ensure that it will be able to continue as a going concern while maximizing the return to stakeholders through the optimization of the debt and equity balance. The capital structure of the Company consists of debt (Note 16) and equity attributable to common shareholders, comprising of issued capital (Note 17), accumulated reserves (Note 18) and retained earnings. The Company is not subject to any externally imposed capital requirements with the exception of complying with the minimum tangible net worth covenant under the credit agreement governing bank debt (Note 16). The Company is in compliance with the debt covenants at June 30, 2021, as described in Note 16.1. 5.2. Categories of Financial Assets and Liabilities The non-revolving term loan, which requires regularly scheduled payments of interest and principal, is carried at amortized cost. Trade receivables from sales of cobalt and other receivables are non-interest bearing and are stated at amortized cost, which approximate fair values due to the short terms to maturity. Where necessary, the non-revolving term loan and the other receivables are reported net of allowances for uncollectable amounts. All other financial assets are reported at fair value. Fair value adjustments on financial assets are reflected as a component of net earnings with the exception of fair value adjustments associated with the Company’s long-term investments in common shares held. As these long-term investments are held for strategic purposes and not for trading, the Company has made a one time, irrevocable election to reflect the fair value adjustments associated with these investments as a component of OCI. Financial liabilities are reported at amortized cost using the effective interest method. The following table summarizes the classification of the Company’s financial assets and liabilities: (in thousands) Note June 30 December 31 Financial assets Financial assets mandatorily measured at FVTNE 1 Cash and cash equivalents 21 $ 235,446 $ 192,683 Trade receivables from provisional concentrate sales, net of fair value adjustment 6, 9 4,034 5,429 Long-term investments - warrants held 14 2,492 3,637 Convertible notes receivable 13 15,979 11,353 Investments in equity instruments designated at FVTOCI 1 Long-term investments - common shares held 14 83,887 196,241 Financial assets measured at amortized cost Non-revolving 23 835 813 Trade receivables from sales of cobalt 9 7,177 - Other accounts receivable 9 1,74 1 454 Total financial assets $ 351,59 1 $ 410,610 Financial liabilities Financial liabilities at amortized cost Accounts payable and accrued liabilities 12,781 13,023 Bank debt 16 - 195,000 Pension liability 2,133 1,670 Total financial liabilities $ 14,914 $ 209,693 1) FVTNE refers to Fair Value Through Net Earnings, FVTOCI refers to Fair Value Through Other Comprehensive Income 5.3. Credit Risk Credit risk is the risk that the counterparty to a financial instrument will cause a financial loss for the Company by failing to discharge its obligations. To mitigate exposure to credit risk on financial assets, the Company has established policies to limit the concentration of credit risk, to ensure counterparties demonstrate minimum acceptable credit worthiness and to ensure liquidity of available funds. The Company closely monitors its financial assets and does not have any significant concentration of credit risk. The Company invests surplus cash in short-term, high credit quality, money market instruments. Additionally, the outstanding accounts receivable from the sales of cobalt are supported by a $10 million letter of credit. Finally, counterparties used to sell precious metals are all large, international organizations with strong credit ratings and the balance of trade receivables on these sales in the ordinary course of business is not significant. Therefore, credit risk associated with trade receivables at June 30, 2021 is considered to be negligible. The Company’s maximum exposure to credit risk related to its financial assets is as follows: (in thousands) Note June 30 December 31 Cash and cash equivalents 21 $ 235,446 $ 192,683 Trade receivables from provisional concentrate sales, net of fair value adjustment 9 4,034 5,429 Trade receivables from sales of cobalt 9 7,177 - Other accounts receivables 9 1,74 1 454 Non-revolving 23 835 813 Convertible notes receivable 13 15,979 11,353 Maximum exposure to credit risk related to financial assets $ 265,21 2 $ 210,732 As it relates to the non-revolving 5.4. Liquidity Risk The Company has in place a rigorous planning and budgeting process to help determine the funds required to support the Company’s normal operating requirements on an ongoing basis and its expansionary plans. The Company ensures that there are sufficient committed loan facilities to meet its short-term business requirements, taking into account its anticipated cash flows from operations and its holdings of cash and cash equivalents. As at June 30, 2021, the Company had cash and cash equivalents of $235 million (December 31, 2020 - $193 million) and working capital of $228 million (December 31, 2020 - $171 million). The Company holds equity investments of several companies (Note 14) with a combined market value at June 30, 2021 of $86 million (December 31, 2020 - $200 million). The daily exchange traded volume of these shares, including the shares underlying the warrants, is not sufficient for the Company to liquidate its position in a short period of time without potentially affecting the market value of the shares. These shares and warrants are held for strategic purposes and are considered long-term investments and therefore, as part of the Company’s planning, budgeting and liquidity analysis process, these investments are not relied upon to provide operational liquidity. The following table summarizes the timing associated with the Company’s remaining contractual payments relating to its financial liabilities. The table reflects the undiscounted cash flows of financial liabilities based on the earliest date on which the Company can be required to pay (assuming that the Company is in compliance with all of its obligations). The table includes both interest and principal cash flows. As at June 30, 2021 (in thousands) 2021 2022 - 2024 2025 - 2026 After 2026 Total Non-derivative financial liabilities Accounts payable and accrued liabilities $ 12,781 $ - $ - $ - $ 12,781 Performance share units 1 - 19,620 - - 19,620 Pension liability 2 2,133 - - - 2,133 Lease liability 455 2,781 345 - 3,581 Total $ 15,369 $ 22,401 $ 345 $ - $ 38,115 1) Assumes a weighted average performance factor of 179% (see Note 19.1). 2) Any benefits under the SERP will be paid out to the employee over a 10-year period, or at the employee’s election, a shorter period upon the employee’s retirement from the Company. 5.5. Currency Risk The Company undertakes certain transactions denominated in Canadian dollars, including certain operating expenses and the acquisition of strategic long-term investments. As a result, the Company is exposed to fluctuations in the value of the Canadian dollar relative to the United States dollar. The carrying amounts of the Company’s Canadian dollar denominated monetary assets and monetary liabilities at the end of the reporting period are as follows: (in thousands) June 30 2021 December 31 Monetary assets Cash and cash equivalents $ 705 $ 5,041 Accounts receivable 136 71 Long-term investments - common shares held 83,463 195,816 Long-term investments - warrants held 2,492 3,637 Convertible note receivable 15,979 11,353 Non-revolving 835 813 Other long-term assets 3,615 3,519 Total Canadian dollar denominated monetary assets $ 107,225 $ 220,250 Monetary liabilities Accounts payable and accrued liabilities $ 6,174 $ 8,011 Performance share units 15,726 23,405 Lease liability 2,218 2,403 Pension liability 2,133 1,670 Total Canadian dollar denominated monetary liabilities $ 26,251 $ 35,489 The following tables detail the Company’s sensitivity to a 10% increase or decrease in the Canadian dollar relative to the United States dollar, representing the sensitivity used when reporting foreign currency risk internally to key management personnel and represents management’s assessment of the reasonably possible change in exchange rates. As at June 30, 2021 Change in Canadian Dollar (in thousands) 10% Increase 10% Decrease Increase (decrease) in net earnings $ (249 ) $ 249 Increase (decrease) in other comprehensive income 8,346 (8,346 ) Increase (decrease) in total comprehensive income $ 8,097 $ (8,097 ) As at December 31, 2020 Change in Canadian Dollar (in thousands) 10% Increase 10% Decrease Increase (decrease) in net earnings $ (1,105 ) $ 1,105 Increase (decrease) in other comprehensive income 19,582 (19,582 ) Increase (decrease) in total comprehensive income $ 18,477 $ (18,477 ) 5.6. Interest Rate Risk The Company is exposed to interest rate risk on its outstanding borrowings and short-term investments. Presently, the Company has no outstanding borrowings, and historically all borrowings have been at floating interest rates. The Company monitors its exposure to interest rates and has not entered into any derivative contracts to manage this risk. During the three months ended June 30, 2021, the Company had no outstanding borrowings while during the six months ended June 30, 2021, the weighted average effective interest rate paid by the Company on its outstanding borrowings was 1.17%. During the three and six months ended June 30, 2020, the weighted average effective interest rate paid by the Company on its outstanding borrowings was 1.97% and 2.53%, respectively. During the three and six months ended June 30, 2021, a fluctuation in interest rates of 100 basis points (1 percent) would have impacted the amount of interest expensed by approximately $Nil and $0.2 million, respectively, as compared to $2 million and $4 million during the comparable periods of the prior year. 5.7. Other Price Risk The Company is exposed to equity price risk as a result of holding long-term investments in common shares of various companies. The Company does not actively trade these investments. If equity prices had been 10% higher or lower at the respective balance sheet date, other comprehensive income for the three and six months ended June 30, 2021 would have increased/decreased by approximately $8 million as a result of changes in the fair value of common shares held, as compared to $26 million for the comparable periods of the previous year. 5.8. Fair Value Estimation The Company classifies its fair value measurements within a fair value hierarchy, which reflects the significance of the inputs used in making the measurements as defined in IFRS 13 – Fair Value Measurements (“IFRS 13”). Level 1 - Unadjusted quoted prices at the measurement date for identical assets or liabilities in active markets. Level 2 - Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 - Unobservable inputs which are supported by little or no market activity. The following table sets forth the Company’s financial assets and liabilities measured at fair value by level within the fair value hierarchy. As required by IFRS 13, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. June 30, 2021 (in thousands) Note Total Level 1 Level 2 Level 3 Cash and cash equivalents 21 $ 235,446 $ 235,446 $ - $ - Trade receivables from provisional concentrate sales, net of fair value adjustment 9 4,034 - 4,034 - Long-term investments - common shares held 14 83,887 83,887 - - Long-term investments - warrants held 14 2,492 - 2,492 - Kutcho Convertible Note 13 15,979 - - 15,979 $ 341,838 $ 319,333 $ 6,526 $ 15,979 December 31, 2020 (in thousands) Note Total Level 1 Level 2 Level 3 Cash and cash equivalents 21 $ 192,683 $ 192,683 $ - $ - Trade receivables from provisional concentrate sales, net of fair value adjustment 9 5,429 - 5,429 - Long-term investments - common shares held 14 196,241 196,241 - - Long-term investments - warrants held 14 3,637 - 3,637 - Kutcho Convertible Note 13 11,353 - - 11,353 $ 409,343 $ 388,924 $ 9,066 $ 11,353 The non-revolving non-interest non-revolving The Company’s bank debt (Note 16.1) is reported at amortized cost using the effective interest method. The carrying value of the bank debt approximates its fair value. 5.8.1. Valuation Techniques for Level 1 Assets Cash and Cash Equivalents The Company’s cash and cash equivalents are valued using quoted market prices in active markets and, as such, are classified within Level 1 of the fair value hierarchy. Long-Term Investments in Common Shares Held The Company’s long-term investments in common shares held are valued using quoted market prices in active markets and, as such, are classified within Level 1 of the fair value hierarchy. The fair value of the long-term investments in common shares held is calculated as the quoted market price of the common share multiplied by the quantity of shares held by the Company. 5.8.2. Valuation Techniques for Level 2 Assets Accounts Receivable Arising from Sales of Metal Concentrates The Company’s trade receivables and accrued liabilities from provisional concentrate sales are valued based on forward prices of gold and silver to the expected date of final settlement (Note 6). As such, these receivables and/or liabilities are classified within Level 2 of the fair value hierarchy. Long-Term Investments in Warrants Held The fair value of the Company’s long-term investments in warrants held that are not traded in an active market are determined using a Black-Scholes model based on assumptions including risk free interest rate, expected dividend yield, expected volatility and expected warrant life which are supported by observable current market conditions and as such are classified within Level 2 of the fair value hierarchy. The use of reasonably possible alternative assumptions would not significantly affect the Company’s results. 5.8.3. Valuation Techniques for Level 3 Assets Convertible Note Receivable The fair value of the Kutcho Convertible Note (Note 13), which is not traded in an active market, is determined by discounting the stream of future interest and principal payments at the rate of interest prevailing at the balance sheet date for instruments of similar term and risk (the market interest rate), and adding this value to the value of the convertibility feature which is estimated using a Black-Scholes model based on assumptions including risk free interest rate, expected dividend yield, expected volatility and expected remaining life of the respective convertible notes receivable. As the expected volatility and market interest rate are not observable inputs, this convertible note receivable is classified within Level 3 of the fair value hierarchy and any changes in fair value are reflected on the Consolidated Statement of Earnings under the classification Other (Income) Expense (Note 8). As it relates to the Kutcho Convertible Note, management estimates that the market interest rate on similar borrowings without the conversion feature was approximately 29% and has used an implied volatility of 30% in valuing the convertibility feature. Holding all other variables constant, a fluctuation in interest rates of 1% and a fluctuation in the implied volatility used of 5% would have impacted the valuation as below: As at June 30, 2021 Change in interest rate Change in volatility (in thousands) Increase 1% Decrease 1% Increase 5% Decrease 5% Kutcho Convertible Note $ (369) $ 382 $ 560 $ (567)

Revenue from precious metal credit sales is recognized at the time of the sale of such credits, which is also the date that control of the precious metal is transferred to the customer. The Company will occasionally enter into forward contracts in relation to precious metal deliveries that it is highly confident will occur within a given quarter. No forward contracts were outstanding at June 30, 2021 or December 31, 2020. The sales price is fixed at the delivery date based on either the terms of these short-term forward sales contracts or the spot price of precious metal. Concentrate Sales Under certain PMPAs, gold and/or silver is acquired from the mine operator in concentrate form, which is then sold under the terms of the concentrate sales contracts to third-party smelters or traders. Where the Company acquires precious metal in concentrate form, final precious metal prices are set on a specified future quotational period (the “Quotational Period”) pursuant to the concentrate sales contracts with third-party smelters, typically one to three months after the shipment date, based on market prices for precious metal. The contracts, in general, provide for a provisional payment based upon provisional assays and quoted gold and silver prices. Final settlement is based upon the average applicable price for the Quotational Period applied to the actual number of precious metal ounces recovered calculated using confirmed smelter weights and settlement assays. Revenues and the associated cost of sales are recorded on a gross basis under these contracts at the time title passes to the customer, which is also the date that control of the precious metal is transferred to the customer. The Company has concluded that the adjustments relating to the final assay results for the quantity of concentrate sold and the retroactive pricing adjustment for the Quotational Period are not significant and do not constrain the recognition of revenue. Cobalt Sales Cobalt is sold to a third-party sales agent who then onsells the cobalt to Wheaton approved third party customers. Revenue from the sale of cobalt is recognized once the third party customer and sales terms have been agreed to between Wheaton and the third-party sales agent, which is also the date that control of the cobalt is transferred to the third-party sales agent.

Acquisition of Santo Domingo Precious Metals Purchase Agreement On March 25, 2021, the Company announced that it had entered into a PMPA with Capstone in respect to the Santo Domingo project located in the Atacama Region of Chile. Upon closing, the Company will purchase 100% of the payable gold production until 285,000 ounces have been delivered, thereafter dropping to 67% of payable gold production for the life of the mine. The Company will pay Capstone a total upfront cash consideration of $290 million, $30 million of which was paid on April 21, 2021 and the remainder of which is payable during construction of the Santo Domingo project, subject to customary conditions being satisfied, including Capstone attaining sufficient financing to cover total expected capital expenditures. In addition, Wheaton will make ongoing payments for gold ounces delivered equal to 18% of the spot gold price until the market value of gold delivered to the Company, net of the per ounce cash payment, exceeds the initial upfront cash deposit, and 22% of the spot gold price thereafter.

Early Deposit Mineral Stream Interests	11. Early Deposit Mineral Stream Interests Early deposit mineral stream interests represent agreements relative to early stage development projects whereby Wheaton can choose not to proceed with the agreement once certain documentation has been received including, but not limited to, feasibility studies, environmental studies and impact assessment studies (please see Note 25 for more information). Once Wheaton has elected to proceed with the agreement, the carrying value of the stream will be transferred to Mineral Stream Interests. The following table summarizes the early deposit mineral stream interests currently owned by the Company: Attributable Production to be Purchased Early Deposit Mineral Stream Interests Mine Owner Location of Mine Upfront Consideration 1 Upfront Consideration to be Paid 1, 2 Total Upfront Consideration¹ Gold Silver Term of Agreement Toroparu Gran Colombia Guyana $ 15,500 $ 138,000 $ 153,500 10% 50% Life of Mine Cotabambas Panoro Peru 10,750 129,250 140,000 25% ³ 100% ³ Life of Mine Kutcho Kutcho Canada 7,000 58,000 65,000 100% 4 100% 4 Life of Mine $ 33,250 $ 325,250 $ 358,500 1) Expressed in thousands of United States dollars; excludes closing costs and capitalized interest, where applicable. 2) Please refer to Note 25 for details of when the remaining upfront consideration to be paid becomes due. 3) Once 90 million silver equivalent ounces attributable to Wheaton have been produced, the attributable production will decrease to 16.67% of gold production and 66.67% of silver production for the life of mine. 4) Once 51,000 ounces of gold and 5.6 million ounces of silver have been delivered to Wheaton, the stream will decrease to 66.67% of gold and silver production for the life of mine.

Mineral Royalty Interest	12. Mineral Royalty Interest On January 5, 2021, the Company purchased from Alexco, for $3 million (Cdn$4 million), a 2.0% net smelter return royalty interest on the first 600,000 ounces of gold mined from ore extracted from the Golden Predator Exploration Ltd. (“Golden Predator”) owned Brewery Creek quartz mineral claims (the “Brewery Creek Mineral Claims”) located in the Yukon Territories, Canada and any mineral tenure derived therefrom, and a 2.75% net smelter returns royalty interest thereafter (the “Brewery Creek Royalty”). The Brewery Creek Royalty agreement provides, among other things, that Golden Predator may reduce the 2.75% net smelter returns royalty interest to 2.125%, on payment of the sum of Cdn$2 million to Wheaton. Additionally, the Company has a 0.5% net smelter return royalty interest in the Metates properties (the “Metates Royalty”) located in Mexico from Chesapeake Gold Corp. (“Chesapeake”) for the life of mine. The carrying cost of the Metates Royalty is $3 million. The Company also has a right of first refusal on any silver streaming, royalty or any other transaction on the Metates properties. To date, no revenue has been recognized and no depletion has been taken with respect to these royalty agreements.

Convertible Note Receivable	13. Convertible Notes Receivable Kutcho Copper Corp. Effective December 14, 2017, in connection with the Kutcho Early Deposit Agreement, the Company advanced to Kutcho $16 million (Cdn$20 million) and received the Kutcho Convertible Note. The Kutcho Convertible Note, which has a seven year term to maturity, carries interest at 10% per annum, compounded and payable semi-annually. Kutcho elected to defer the first seven interest payments, with all deferred payments being due no later than December 31, 2023. The deferred interest carries interest at 15% per annum, compounded semi-annually. At any time prior to the maturity date, the Company has the right to convert all or any part of the outstanding amount of the Kutcho Convertible Note, excluding outstanding deferred interest, into common shares of Kutcho at Cdn$0.8125 per share. Kutcho has the right to repay the Kutcho Convertible Note early, subject to the applicable pre-payment ● 20% of the outstanding amount if pre-paid ● 15% of the outstanding amount if pre-paid Gold X Mining Corp. Effective December 24, 2019, in connection with the Toroparu Early Deposit Agreement (Note 11), the Company advanced $10 million to Gold X as part of a $20 million 10% secured convertible debenture private placement offering completed by Gold X (the “Gold X Convertible Note”). The Gold X Convertible Note carried interest at 10% per annum, compounded semi-annually and payable annually. Effective July 14, 2020, the Company elected to convert the outstanding principal on the Gold X Convertible Note into common shares of Gold X at Cdn$3.20 per share, with the outstanding amounts being converted into Canadian dollars using the exchange rate published by the Bank of Canada on July 13, 2020. In addition, the accrued interest on the Gold X Convertible Note was converted to common shares of Gold X at Cdn$3.57 per share. As a result, on July 14, 2020 the Company received 4,467,317 common shares of Gold X and the Gold X Convertible Note was retired. On June 4, 2021, Gran Colombia Gold Corp. (“Gran Colombia”) completed the acquisition of all of the issued and outstanding common shares of Gold X and as a result, all of the Company’s common shares of Gold X were exchanged for common shares of Gran Colombia at an exchange rate of 0.6948 common shares of Gran Colombia for each Gold X common share. Convertible Notes Receivable Valuation Summary The Kutcho Convertible Note is revalued quarterly by discounting the stream of future interest and principal payments at the rate of interest prevailing at the balance sheet date for instruments of similar term and risk, and adding this value to the value of the convertibility feature which is estimated using a Black-Scholes model based on assumptions including risk free interest rate, expected dividend yield, expected volatility and expected remaining life of the Kutcho Convertible Note. The value of the Gold X Convertible Note, which was converted into common shares of Gold X effective July 14, 2020, was determined by reference to the value of the shares received. Prior to electing to convert this convertible note receivable into common shares of Gold X, the Gold X Convertible Note was revalued quarterly using the same methodology as the Kutcho Convertible Note above. A summary of the fair value of these convertible instruments and the fair value changes recognized as a component of the Company’s net earnings during the three and six months ended June 30, 2021 and 2020 is presented below: Three Months Ended June 30, 2021 (in thousands) Fair Value at Mar 31, 2021 Amount Advanced Value Converted into Shares Fair Value Adjustment Gains (Losses) Fair Value at Jun 30, 2021 Kutcho $ 12,591 $ - $ - $ 3,388 $ 15,979 Three Months Ended June 30, 2020 (in thousands) Fair Value at Mar 31, 2020 Amount Advanced Value Converted into Shares Fair Value Adjustment Gains (Losses) Fair Value at Jun 30, 2020 Kutcho $ 10,836 $ - $ - $ - $ 10,836 Gold X 10,230 - - 3,267 13,497 Total $ 21,066 $ - $ - $ 3,267 $ 24,333 Six Months Ended June 30, 2021 (in thousands) Fair Value at Dec 31, 2020 Amount Advanced Value Converted into Shares Fair Value Adjustment Gains (Losses) Fair Value at Jun 30, 2021 Kutcho $ 11,353 $ - $ - $ 4,626 $ 15,979 Six Months Ended June 30, 2020 (in thousands) Fair Value at Dec 31, 2019 Amount Advanced Value Converted into Shares Fair Value Adjustment Fair Value at Jun 30, 2020 Kutcho $ 11,837 $ - $ - $ (1,001 ) $ 10,836 Gold X 10,019 - - 3,478 13,497 Total $ 21,856 $ - $ - $ 2,477 $ 24,333

As such, the Company has elected to reflect any fair value adjustments, net of tax, as a component of other comprehensive income (“OCI”). The cumulative gain or loss will not be reclassified to net earnings on disposal of these long-term investments but is reclassified to retained earnings. While long-term investments in warrants are also held for long-term strategic purposes, they meet the definition of a derivative and therefore are classified as financial assets with fair value adjustments being recorded as a component of net earnings under the classification Other (Income) Expense. Warrants that do not have a quoted market price are valued using a Black-Scholes option pricing model. By holding these long-term investments, the Company is inherently exposed to various risk factors including currency risk, market price risk and liquidity risk.

On June 9, 2021, the term of the Company’s $2 billion revolving term loan (“Revolving Facility”) was extended by an additional year, with the facility now maturing on June 9, 2026. The Company incurred fees of $2 million in relation to this extension. The Company’s Revolving Facility has financial covenants which require the Company to maintain: (i) a net debt to tangible net worth ratio of less than or equal to 0.75:1; and (ii) an interest coverage ratio of greater than or equal to 3.00:1. Only cash interest expenses are included for the purposes of calculating the interest coverage ratio. The Company is in compliance with these debt covenants as at June 30, 2021. At the Company’s option, amounts drawn under the Revolving Facility incur interest based on the Company’s leverage ratio at either (i) LIBOR plus 1.00% to 2.05%; or (ii) the Bank of Nova Scotia’s Base Rate plus 0.00% to 1.05%. Upon the anticipated discontinuance of the LIBOR benchmark rate, amounts drawn under the Revolving Facility will incur interest based on the Secured Overnight Financing Rate (“SOFR”) or an alternate benchmark rate. Under both options, the interest rate shall not be less than 0%. The Revolving Facility, which is classified as a financial liability and reported at amortized cost using the effective interest method, can be drawn down at any time to finance acquisitions, investments or for general corporate purposes. 16.2.

Each warrant entitles the holder the right to purchase one of the Company’s common shares. 18.2. Share Purchase Options The Company has established an equity settled share purchase option plan whereby the Company’s Board of Directors may, from time to time, grant options to employees or consultants. The maximum term of any share purchase option may be ten years, but generally options are granted with a term to expiry of five to seven years. The exercise price of an option is not less than the closing price on the TSX on the last trading day preceding the grant date. The vesting period of the options is determined at the discretion of the Company’s Board of Directors at the time the options are granted, but generally vest over a period of two or three years. Each share purchase option converts into one common share of Wheaton on exercise. No amounts are paid or payable by the recipient on receipt of the option. The options do not carry rights to dividends or voting rights. Options may be exercised at any time from the date of vesting to the date of their expiry, subject to certain black-out The Company expenses the fair value of share purchase options that are expected to vest on a straight-line basis over the vesting period using the Black-Scholes option pricing model to estimate the fair value for each option at the date of grant. The Black-Scholes model was developed for use in estimating the fair value of traded options that have no vesting restrictions. The model requires the use of subjective assumptions, including expected share price volatility. Historical data has been considered in setting the assumptions. Expected volatility is determined by considering the trailing 30-month Six Months Ended June 30 2021 2020 Black-Scholes weighted average assumptions Grant date share price and exercise price Cdn$49.86 Cdn$33.47 Expected dividend yield 1.53% 1.78% Expected volatility 35% 30% Risk-free interest rate 0.51% 0.52% Expected option life, in years 3.0 2.5 Weighted average fair value per option granted Cdn$10.69 Cdn$5.57 Number of options issued during the period 317,560 451,110 Total fair value of options issued (000’s) $ 2,720 $ 1,807 No stock options were issued during the three months ended June 30, 2021 and June 30, 2020, respectively. A continuity schedule of the Company’s outstanding share purchase options from January 1, 2020 to June 30, 2021 is presented below: Number of Options Outstanding Weighted Average Exercise Price At January 1, 2020 2,394,490 Cdn$27.08 Granted (fair value - $2 million or Cdn$5.57 per option) 451,110 33.47 Exercised (374,235) 24.83 At March 31, 2020 2,471,365 Cdn$28.91 Exercised (486,720) 26.25 At June 30, 2020 1,984,645 Cdn$29.40 Exercised (195,408) 25.98 Forfeited (2,420) 32.01 At December 31, 2020 1,786,817 Cdn$29.54 Granted (fair value - $3 million or Cdn$10.69 per option) 317,560 49.86 Exercised (258,000) 23.24 At March 31, 2021 1,846,377 Cdn$33.90 Exercised (31,745) 28.29 At June 30, 2021 1,814,632 Cdn$33.92 As it relates to share purchase options, during the three months ended June 30, 2021, the weighted average share price at the time of exercise was Cdn$56.47 per share (six months - Cdn$50.02 per share), as compared to Cdn$59.87 per share (six months - Cdn$50.87 per share) during the comparable period in 2020. 18.3. Restricted Share Units (“RSUs”) The Company has established an RSU plan whereby RSUs will be issued to eligible employees or directors as determined by the Company’s Board of Directors or the Company’s Compensation Committee. RSUs give the holder the right to receive a specified number of common shares at the specified vesting date. RSUs generally vest over a period of two to three years. Compensation expense related to RSUs is recognized over the vesting period based upon the fair value of the Company’s common shares on the grant date and the awards that are expected to vest. The fair value is calculated with reference to the closing price of the Company’s common shares on the TSX on the business day prior to the date of grant. RSU holders receive a cash payment based on the dividends paid on the Company’s common shares in the event that the holder of a vested RSU has elected to defer the release of the RSU to a future date. This cash payment is reflected as a component of net earnings under the classification General and Administrative. A continuity schedule of the Company’s restricted share units outstanding from January 1, 2020 to June 30, 2021 is presented below: Number of RSUs Outstanding Weighted Average Intrinsic Value At January 1, 2020 366,323 $21.67 Granted (fair value - $3 million) 131,730 24.08 Released (124,910) 22.29 At March 31, 2020 373,143 $22.32 Granted 1,230 43.61 Released (3,495) 20.85 At June 30, 2020 370,878 $22.40 Forfeited (620) 24.11 At December 31, 2020 370,258 $22.40 Granted (fair value - $4 million) 96,680 39.95 Released (116,180) 24.10 At March 31, 2021 350,758 $26.68 Released (700) 22.12 At June 30, 2021 350,058 $26.69 18.4. Long-Term Investment Revaluation Reserve The Company’s long-term investments in common shares (Note 14) are held for long-term strategic purposes and not for trading purposes. The Company has chosen to designate these long-term investments in common shares as financial assets with fair value adjustments being recorded as a component of OCI as it believes that this provides a more meaningful presentation for long-term strategic investments, rather than reflecting changes in fair value as a component of net earnings. As some of these long-term investments are denominated in Canadian dollars, changes in their fair value is affected by both the change in share price in addition to changes in the Cdn$/US$ exchange rate. Where the fair value of a long-term investment in common shares held exceeds its tax cost, the Company recognizes a deferred income tax liability. To the extent that the value of the long-term investment subsequently declines, the deferred income tax liability is reduced. However, where the fair value of the long-term investment decreases below the tax cost, the Company does not recognize a deferred income tax asset on the unrealized capital loss unless it is probable that the Company will generate future capital gains that will offset the loss. A continuity schedule of the Company’s long-term investment revaluation reserve from January 1, 2020 to June 30, 2021 is presented below: (in thousands) Change in Deferred Tax Recovery (Expense) Total At January 1, 2020 $ 57,062 $ (9,853) $ 47,209 Unrealized gain (loss) on LTIs 1 (154,143) 9,853 (144,290) At March 31, 2020 $ (97,081) $ - $ (97,081) Unrealized gain (loss) on LTIs 1 105,521 (4,698) 100,823 Reallocate reserve to retained earnings upon disposal of LTIs 1 (30) 4 (26) At June 30, 2020 $ 8,410 $ (4,694) $ 3,716 Unrealized gain (loss) on LTIs 1 74,478 (7,021) 67,457 Reallocate reserve to retained earnings upon disposal of LTIs 1 (60,785) 4,747 (56,038) At December 31, 2020 $ 22,103 $ (6,968) $ 15,135 Unrealized gain (loss) on LTIs 1 (217) (2,137) (2,354) Reallocate reserve to retained earnings upon disposal of LTIs 1 (60,530) 7,411 (53,119) At March 31, 2021 $ (38,644) $ (1,694) $ (40,338) Unrealized gain (loss) on LTIs 1 (2,326) (479) (2,805) At June 30, 2021 $ (40,970) $ (2,173) $ (43,143) 1) LTIs refers to long-term investments in common shares held.

Stock Based Compensation	19. Stock Based Compensation The Company’s stock based compensation consists of share purchase options (Note 18.2), restricted share units (Note 18.3) and performance share units (Note 19.1). The accrued value of share purchase options and restricted share units are reflected as reserves in the shareholder’s equity section of the Company’s balance sheet while the accrued value associated with performance share units is reflected as an accrued liability. 19.1. Performance Share Units (“PSUs”) The Company has established a Performance Share Unit Plan (“the PSU plan”) whereby PSUs will be issued to eligible employees as determined by the Company’s Board of Directors or the Company’s Compensation Committee. PSUs issued under the PSU plan entitle the holder to a cash payment at the end of a three year performance period equal to the number of PSUs granted, multiplied by a performance factor and multiplied by the fair market value of a Wheaton common share on the expiry of the performance period. The performance factor can range from 0% to 200% and is determined by comparing the Company’s total shareholder return to those achieved by various peer companies, the Philadelphia Gold and Silver Index and the price of gold and silver. Compensation expense for the PSUs is recorded on a straight-line basis over the three year vesting period. The amount of compensation expense is adjusted at the end of each reporting period to reflect (i) the fair value of common shares; (ii) the number of PSUs anticipated to vest; and (iii) the anticipated performance factor. A continuity schedule of the Company’s outstanding PSUs (assuming a performance factor of 100% is achieved over the performance period) and the Company’s PSU accrual from January 1, 2020 to June 30, 2021 is presented below: (in thousands, except for number of PSUs outstanding) Number of Outstanding PSU accrual At January 1, 2020 604,692 $ 19,069 Granted 193,830 - Accrual related to the fair value of the PSUs outstanding - 3,277 Foreign exchange adjustment - (1,303) At March 31, 2020 798,522 $ 21,043 Accrual related to the fair value of the PSUs outstanding - 10,097 Foreign exchange adjustment - 395 Paid (193,716) (10,965) At June 30, 2020 604,806 $ 20,570 Accrual related to the fair value of the PSUs outstanding - 8,151 Foreign exchange adjustment - 1,521 Paid (10,426) (1,157) Forfeited (1,230) (5) At December 31, 2020 593,150 $ 29,080 Granted 134,180 - Accrual related to the fair value of the PSUs outstanding - 305 Foreign exchange adjustment - 292 At March 31, 2021 727,330 $ 29,677 Accrual related to the fair value of the PSUs outstanding - 6,672 Foreign exchange adjustment - 200 Paid (213,820) (16,929) At June 30, 2021 513,510 $ 19,620 A summary of the PSUs outstanding at June 30, 2021 is as follows: Year of Grant Year of Maturity Number outstanding Estimated Value Anticipated Performance Factor at Maturity Percent of Jun 30, 2021 PSU Liability at Jun 30, 2021 2019 2022 186,730 $46.63 199% 76% 13,113 2020 2023 192,600 $46.00 154% 43% 5,853 2021 2024 134,180 $45.47 111% 10% 654 513,510 $ 19,620

Contracts where the payment is a fixed amount per ounce of metal delivered are subject to an annual inflationary increase, with the exception of Loma de La Plata and Sudbury. Additionally, should the prevailing market price for the applicable metal be lower than this fixed amount, the per ounce cash payment will be reduced to the prevailing market price, with the exception of Yauliyacu where the per ounce cash payment will not be reduced below $4.48, subject to an annual inflationary factor. 2) Subject to an increase to $9.90 per ounce of silver and $550 per ounce of gold after the initial 40-year 3) Under the terms of the San Dimas PMPA, the Company is entitled to an amount equal to 25% of the payable gold production plus an additional amount of gold equal to 25% of the payable silver production converted to gold at a fixed gold to silver exchange ratio of 70:1 from the San Dimas mine. If the average gold to silver price ratio decreases to less than 50:1 or increases to more than 90:1 for a period of 6 months or more, then the “70” shall be revised to “50” or “90”, as the case may be, until such time as the average gold to silver price ratio is between 50:1 to 90:1 for a period of 6 months or more in which event the “70” shall be reinstated. Currently, the fixed gold to silver exchange ratio is 70:1. 4) The Company is committed to purchase 4.5% of Stillwater palladium production until 375,000 ounces are delivered to the Company, thereafter 2.25% of Stillwater palladium production until 550,000 ounces are delivered to the Company and 1% of Stillwater palladium production thereafter for the life of mine. 5) To be increased to 22% once the market value of metal delivered to Wheaton, net of the per ounce cash payment, exceeds the initial upfront cash deposit. 6) Once the Company has received 31 million pounds of cobalt, the Company’s attributable cobalt production will be reduced to 21.2%. 7) To be increased to 22% once the market value of cobalt delivered to Wheaton, net of the per pound cash payment, exceeds the initial upfront cash deposit. Additionally, on each sale of cobalt, the Company is committed to pay a variable commission depending on the market price of cobalt. 8) The Company will purchase an amount equal to 100% of the first 1.5 million ounces of payable silver produced at Yauliyacu per annum and 50% of any excess. 9) Should the market price of silver exceed $20 per ounce, in addition to the $8.98 per ounce, the Company is committed to pay Glencore an additional amount for each ounce of silver delivered equal to 50% of the excess, to a maximum of $10 per ounce, such that when the market price of silver is $40 or above, the Company will pay Glencore $18.98 per ounce of silver delivered. 10) Wheaton only has the rights to silver contained in concentrate containing less than 15% copper at the Aljustrel mine. 11) The Company is committed to acquire 100% of the first 30,000 ounces of gold produced per annum and 50% thereafter. 12) The Company is currently negotiating an amendment to the Minto PMPA such that the cash payment per ounce of gold delivered will be the lower of 65% of the spot price of gold and $1,250. This proposed amended pricing will end on the earlier of (i) January 27, 2023; or (ii) once 27,000 ounces of gold have been delivered to the Company. Once this proposed amended pricing ends, the cash payment per ounce of gold delivered will be the lower of 50% of the spot price of gold and $1,000. In the event that the parties are unable to finalize the terms of the proposed amendment, the production payment will remain as set out in the existing Minto PMPA, being a fixed price of $325 per ounce. 13) Effective July 2020, the price paid per ounce of silver delivered under the Keno Hill PMPA has been modified to be between 10% of the spot price of silver when the market price of silver is at or above $23.00 per ounce, to 90% of the spot price of silver when the market price of silver is at or below $15.00 per ounce. 14) Terms of the agreement not yet finalized. 15) Once Wheaton has received 190,000 ounces of gold and 2.15 million ounces of silver under the Marmato PMPA the Company’s attributable gold and silver production will be reduced to 3.25% and 50%, respectively. 16) To be increased to 22% of the spot price once the market value of gold and silver delivered to the Company, net of the per ounce cash payment, exceeds the initial upfront cash deposit. 17) Once Wheaton has received 10 million ounces, the Company’s attributable silver production will be reduced to 33% of silver production for the life of the mine. 18) Once 90 million silver equivalent ounces attributable to Wheaton have been produced, the attributable production will decrease to 16.67% of gold production and 66.67% of silver production for the life of mine. 19) Once 51,000 ounces of gold and 5.6 million ounces of silver have been delivered to Wheaton, attributable production will decrease to 66.67% of gold and silver production for the life of mine. 20) Once the Company has received 285,000 ounces of gold the Company’s attributable gold production will be reduced to 67%.

Under the Rosemont PMPA, the Company is permitted to elect to pay the deposit in cash or the delivery of common shares. Additionally, the Company will be entitled to certain delay payments, including where construction ceases in any material respect, or if completion is not achieved within agreed upon timelines. Hudbay and certain affiliates have provided the Company with a corporate guarantee and other security. On August 1, 2019, Hudbay announced that the U.S. District Court for the District of Arizona (“Court”) issued a ruling in the lawsuits challenging the U.S. Forest Service’s issuance of the Final Record of Decision (“FROD”) for the Rosemont project in Arizona. The Court ruled to vacate and remand the FROD such that Rosemont cannot proceed with construction at this time. On June 22, 2020 Hudbay announced that they had filed the initial brief with the U.S. Court of Appeals for the Ninth Circuit in relation to appealing this decision. As per Hudbay’s MD&A for the year ended December 31, 2020, final briefs were filed in November 2020 and the oral hearing was completed in early February 2021. Hudbay has indicated that a decision from the Ninth Circuit is expected in the second half of 2021. Loma de La Plata Under the terms of the Loma de La Plata PMPA, the Company is committed to pay Pan American Silver Corp. (“Pan American”) total upfront cash payments of $32 million following the satisfaction of certain conditions, including Pan American receiving all necessary permits to proceed with the mine construction and the Company finalizing the definitive terms of the PMPA. Marmato Under the terms of the Marmato PMPA, the Company is committed to pay Aris Gold total upfront cash payments of $110 million. Of this amount, $34 million was paid on April 15, 2021; $4 million is payable on or before October 15, 2021; and the remaining amount is payable during the construction of the MDZ development portion of the Marmato mine, subject to customary conditions. Toroparu Under the terms of the Toroparu Early Deposit Agreement, the Company is committed to pay Gran Colombia (formerly Gold X) an additional $138 million, payable on an installment basis to partially fund construction of the mine. Gran Colombia is to deliver certain feasibility documentation by December 31, 2021. Following the delivery of this documentation (or after December 31, 2021 if the feasibility documentation has not been delivered to Wheaton by such date) Wheaton may elect to (i) not proceed with the agreement or (ii) not pay the balance of the upfront consideration and reduce the gold stream percentage from 10% to 0.909% and the silver stream percentage from 50% to nil. If option (i) is chosen, Wheaton will be entitled to a return of the amounts advanced less $2 million. If Wheaton elects option (ii), Gran Colombia may elect to terminate the agreement and Wheaton will be entitled to a return of the amount of the deposit already advanced less $2 million. Cotabambas Under the terms of the Cotabambas Early Deposit Agreement, the Company is committed to pay Panoro a total cash consideration of $140 million, of which $11 million has been paid to date. Once certain conditions have been met, the Company will advance an additional $3 million to Panoro, spread over up to three years. Following the delivery of a bankable definitive feasibility study, environmental study and impact assessment, and other related documents (collectively, the “Cotabambas Feasibility Documentation”), and receipt of permits and construction commencing, the Company may then advance the remaining deposit or elect to terminate the Cotabambas Early Deposit Agreement. If the Company elects to terminate, the Company will be entitled to a return of the portion of the amounts advanced less $2 million payable upon certain triggering events occurring. Kutcho Under the terms of the Kutcho Early Deposit Agreement, the Company is committed to pay Kutcho a total cash consideration of $65 million, of which $7 million has been paid to date. The remaining $58 million will be advanced on an installment basis to partially fund construction of the mine once certain conditions have been satisfied. The Company will be required to make an additional payment to Kutcho, of up to $20 million, if processing throughput is increased to 4,500 tonnes per day or more within 5 years of attaining commercial production. Salobo The Salobo mine currently has a mill throughput capacity of 24 million tonnes per annum (“Mtpa”). In October 2018, Vale’s Board of Directors approved the investment in the Salobo III mine expansion (the “Salobo Expansion”). The Salobo Expansion is proposed to include a third concentrator line and will use Salobo’s existing infrastructure. Vale anticipates that the Salobo Expansion, which is scheduled to start up in the first half of 2022 with a ramp-up If actual throughput is expanded above 28 Mtpa, then under the terms of the Salobo PMPA, Wheaton will be required to make an additional set payment to Vale based on the size of the expansion, the timing of completion and the grade of the material processed. The set payment ranges from $113 million if throughput is expanded beyond 28 Mtpa by January 1, 2036 up to $923 million if throughput is expanded beyond 40 Mtpa by January 1, 2022. Assuming the Salobo III expansion project achieves 12 Mtpa of additional processing capacity (bringing total processing capacity at Salobo to 36 Mtpa) by the end of 2022, the Company would expect to pay an estimated expansion payment of between $570 million to $670 million. The actual amount and timing of any expansion payment may significantly differ from this estimate depending on the size, timing and processed grade of any expansion. Santo Domingo Under the terms of the Santo Domingo PMPA, the Company is committed to pay Capstone total upfront cash payments of $290 million, $30 million of which was paid on April 21, 2021 and the remaining portion of which is payable during the construction of the Santo Domingo project, subject to customary conditions being satisfied, including Capstone attaining sufficient financing to cover total expected capital expenditures. Constancia On May 10, 2021, Wheaton and Hudbay agreed to amend the Constancia streaming agreement so that Hudbay would no longer be required to deliver an additional 8,020 ounces of gold to Wheaton for not mining four million tonnes of ore from Pampacancha by June 30, 2021. As part of this amendment, Hudbay has agreed to increase the fixed gold recoveries that apply to Constancia ore production from 55% to 70% during the reserve life of Pampacancha and if Hudbay mines and processes four million tonnes of ore from the Pampacancha deposit by December 31, 2021, the Company will make an additional deposit payment of $4 million to Hudbay. Canada Revenue Agency – Canada Revenue Agency – 2013-2015 Taxation Years - Domestic Reassessments The Company received Notices of Reassessment in 2018 and 2019 for the 2013 to 2015 taxation years in which the Canada Revenue Agency (“CRA”) is seeking to change the timing of the deduction of upfront payments with respect to the Company’s PMPAs relating to Canadian mining assets, so that the cost of precious metal acquired under these Canadian PMPAs is equal to the cash cost paid on delivery plus an amortized amount of the upfront payment determined on a units-of-production Management believes the Company’s position, as reflected in its filed Canadian income tax returns and consistent with the terms of the PMPAs, that the cost of the precious metal acquired under the Canadian PMPAs is equal to the market value while a deposit is outstanding, and the cash cost thereafter is correct. The Company has filed Notices of Objection and paid 50% of the disputed amounts in order to challenge the Domestic Reassessments. If CRA were to apply the methodology in the Domestic Reassessments to taxation years subsequent to 2015, the Company estimates that losses would arise that could be carried back to reduce tax and interest relating to the Domestic Reassessments to approximately $2 million. Canadian Shareholder Class Action During July 2015, the Company disclosed that the CRA was proposing that they would issue notices of reassessment for federal and provincial tax, transfer pricing penalties, interest and other penalties for the 2005-2010 taxation years (the “Reassessments”). By Notice of Action dated August 10, 2016 (as amended September 2, 2016 and supplemented by Statement of Claim filed September 9, 2016 (collectively, the “Claim”)), proposed representative plaintiff Suzan Poirier commenced proceedings pursuant to the Class Proceedings Act (Ontario) in the Ontario Superior Court of Justice against Wheaton Precious Metals Corp., Randy Smallwood, President and Chief Executive Officer and Gary Brown, Senior Vice President & Chief Financial Officer. The Claim alleges, among other things, misrepresentation pursuant to primary and secondary market civil liability provisions under the Securities Act (Ontario) and its provincial equivalents, common law negligence and negligent misrepresentation. The claim focuses on the Reassessments. The Claim purports to be brought on behalf of proposed a class of persons and entities who acquired common shares of Wheaton Precious Metals Corp. between August 14, 2013 and July 6, 2015 and held some or all of such common shares as of at least July 6, 2015. On July 21, 2020, the Company received a motion record in support of a proposed motion seeking the following (among other relief): (i) leave of the court to commence a secondary market action pursuant to section 138.3(1) of the Securities Act (Ontario) and equivalent provisions in the applicable provincial securities statutes: (ii) certification of the (amended) class and proposed common issues; (iii) leave to file an amended Statement of Claim to include further particulars and to refer to various provincial securities laws; and (iv) the appointment of a new class representative (Ms. Miriam Rosenszajn) in place of Ms. Poirier. It is expected that the certification and leave motions will be jointly heard in October 2021. The Company believes that the allegations are without merit and intends to vigorously defend against this matter. No amounts have been recorded for potential liability arising from this claim as no value has been specified in the statement of claim and the Company cannot reasonably predict the outcome. Tax Contingencies Due to the size, complexity and nature of the Company’s operations, various legal and tax matters are outstanding from time to time, including audits and disputes. Under the terms of the 2018 settlement with the CRA of the transfer pricing dispute relating to the 2005-2010 taxation years (“CRA Settlement”), income earned outside of Canada by the Company’s foreign subsidiaries will not be subject to income tax in Canada under transfer pricing rules. The CRA Settlement principles apply to all taxation years after 2010 subject to there being no material change in facts or change in law or jurisprudence. It is not known or determinable by the Company when any ongoing audits by CRA of international and domestic transactions will be completed, or whether reassessments will be issued, or the basis, quantum or timing of any such potential reassessments, and it is therefore not practicable for the Company to estimate the financial effect, if any, of any ongoing audits. From time to time there may also be proposed legislative changes to law or outstanding legal actions that may have an impact on applicable law or jurisprudence, the outcome, applicability and impact of which is also not known or determinable by the Company. General By their nature, contingencies will only be resolved when one or more future events occur or fail to occur. The assessment of contingencies inherently involves the exercise of significant judgment and estimates of the outcome of future events. If the Company is unable to resolve any of these matters favorably, there may be a material adverse impact on the Company’s financial performance, cash flows or results of operations. In the event that the Company’s estimate of the future resolution of any of the foregoing matters changes, the Company will recognize the effects of the change in its consolidated financial statements in the appropriate period relative to when such change occurs.

Subsequent Events	27. Subsequent Events Declaration of Dividend Under the Company’s dividend policy, the quarterly dividend per common share is targeted to equal approximately 30% of the average cash flow generated by operating activities in the previous four quarters divided by the Company’s then outstanding common shares, all rounded to the nearest cent. To minimize volatility in quarterly dividends, the Company has set a minimum quarterly dividend of $0.13 per common share for the duration of 2021. The declaration, timing, amount and payment of future dividends remain at the discretion of the Board of Directors. On August 12, 2021, the Board of Directors declared a dividend in the amount of $0.15 per common share, with this dividend being payable to shareholders of record on August 27, 2021 and is expected to be distributed on or about September 9, 2021. The Company has implemented a dividend reinvestment plan (“DRIP”) whereby shareholders can elect to have dividends reinvested directly into additional Wheaton common shares at a discount of 1% of the Average Market Price, as defined in the DRIP.

Future Changes in Accounting Policies	3.1. Future Changes to Accounting Policies The IASB has issued the following new or amended standards: Amendment to IAS 16 - Property, Plant and Equipment The amendments to IAS 16 prohibit deducting from the cost of property, plant and equipment the proceeds from selling items produced while bringing the assets to the location and condition necessary for them to be capable of operating in the manner intended by management. Instead, a company will recognize such sales proceeds and related cost in the Statement of Earnings. This amendment is in effect January 1, 2022 with early adoption permitted. The adoption of this guidance is not expected to have a material impact on the Company’s Consolidated Statement of Earnings. Amendment to IAS 12 - Deferred Tax related to Assets and Liabilities arising from a Single Transaction The amendments to IAS 12 clarify that the initial recognition exemption does not apply to transactions in which equal amounts of deductible and taxable temporary differences arise on initial recognition. The amendments are effective for annual reporting periods beginning on or after January 1, 2023. Early application of the amendments is permitted. The amendments apply to transactions that occur on or after the beginning of the earliest comparative period presented. In addition, at the beginning of the earliest comparative period the following would be recognized: ● a deferred tax asset to the extent that it is probable that taxable profit will be available against which the deductible temporary difference can be utilised and a deferred tax liability for all deductible and taxable temporary differences associated with right-of-use ● the cumulative effect of initially applying the amendments as an adjustment to the opening balance of retained earnings (or other component of equity, as appropriate) at that date. The Company is currently evaluating the impact of this amendment.

[1]	As at June 30, 2021, the Company had recognized the tax effect on $21 million of non-capital losses against deferred tax liabilities.
[2]	Other includes capital assets, charitable donation carryforward and PSU and pension liabilities.
[3]	Debt and share financing fees are deducted over a five year period for Canadian income tax purposes. For accounting purposes, debt financing fees are deducted over the term of the credit facility and share financing fees are charged directly to issued capital.
[4]	The Company’s position, as reflected in its filed Canadian income tax returns and consistent with the terms of the PMPAs, is that the cost of the precious metal acquired under the Canadian PMPAs is equal to the market value while a deposit is outstanding (where applicable to an agreement), and the cash cost thereafter. For accounting purposes, the cost of the mineral stream interests is depleted on a unit-of-production basis as described in Note 4.2.
