WHEATON PRECIOUS METALS ANNOUNCES SECOND QUARTER RESULTS FOR 2018 AND DECLARES THIRD QUARTERLY DIVIDEND OF 2018

Vancouver, British Columbia – Wheaton Precious Metals™ Corp. (“Wheaton” or the “Company”) is pleased to announce its results for the second quarter ended June 30, 2018. All figures are presented in United States dollars unless otherwise noted.

In the second quarter of 2018, Wheaton had net earnings of $318 million, which included a $246 million gain on the disposal of the San Dimas silver stream. In the first half of 2018, Wheaton had record gold production from Salobo and generated over $260 million in cash flow. During the second quarter, Wheaton completed the acquisition of a cobalt stream on Vale’s Voisey’s Bay mine, and subsequent to the quarter, Wheaton closed a gold and palladium stream on Sibanye-Stillwater’s Stillwater and East Boulder mines.

Highlights

• The decrease in attributable silver production and the increase in attributable gold production for the three months ended June 30, 2018, was primarily due to the termination of the San Dimas silver purchase agreement and the entering into of the new San Dimas precious metals purchase agreement effective May 10, 2018, with the silver production being further impacted by the expiry of the streaming agreement relative to the Lagunas Norte, Veladero and Pierina mines on March 31, 2018, and lower production at Antamina primarily resulting from mine sequencing.

• The decrease in silver sales volume for the three months ended June 30, 2018, was due to the lower production levels, partially offset by positive changes in the balance of payable silver produced but not yet delivered to Wheaton.

• The increase in gold sales volume for the three months ended June 30, 2018, was primarily the result of increased production levels coupled with positive changes in the balance of payable gold produced but not yet delivered to Wheaton.

• Declared quarterly dividend of $0.09 per common share. This represents an increase of 29% relative to the comparable period in 2017.

• On May 10, 2018, First Majestic Silver Corp. (“First Majestic”) announced that they had closed the previously announced acquisition of Primero Mining Corp. (“Primero”). In connection with this acquisition, the Company has terminated the San Dimas silver purchase agreement and entered into a new San Dimas precious metal purchase agreement with First Majestic, resulting in a gain on disposal of $246 million.

• On June 28, 2018, Wheaton completed the acquisition from Vale S.A. (“Vale”) of a fixed percentage of cobalt production from the Voisey’s Bay mine starting in January 2021.

Subsequent to the Quarter

• On July 25, 2018, the Company, through its wholly owned subsidiary Wheaton Precious Metals International Ltd. (“Wheaton International”), completed the acquisition from Sibanye Gold Limited (“Sibanye-Stillwater”) of a fixed percentage of gold and palladium production from the Stillwater and East Boulder mines (collectively “Stillwater”) effective July 1, 2018.

• On July 17, 2018, the Company acquired 9.99% of the common shares of Adventus Zinc Corporation (“Adventus”) and acquired a right of first refusal on any new streaming or royalty transactions on precious metals on the Adventus existing properties in Ecuador.

Reconfirming Production Guidance

• With the addition of the streams on Voisey’s Bay and Stillwater, Wheaton’s estimated attributable production in 2018 is forecast to be approximately 355,000 ounces of gold, 22.5 million ounces of silver, and 10,400 ounces of palladium.

• Estimated average annual attributable production over the next five years (including 2018) is anticipated to be approximately 385,000 ounces of gold, 25 million ounces of silver, 27,000 ounces of palladium, and starting in 2021, 2.1 million pounds of cobalt per year.

“Wheaton’s high-quality portfolio and strong margins generated over $260 million of operating cash flow in the first half of 2018,” said Randy Smallwood, President and Chief Executive Officer of Wheaton Precious Metals. “Since the beginning of the year, Wheaton made two substantial acquisitions with new streams on Voisey’s Bay and Stillwater. We expect Stillwater to contribute production and cash flow starting in the third quarter of 2018 and Voisey’s Bay starting in 2021.

- 2 -

These additions ideally fit within our existing portfolio as they are both high-margin and long-life mines with significant exploration potential. Given our sector-leading cash flow and revolving credit facility, Wheaton was able to consummate these transactions on an accretive basis for shareholders without having to access additional sources of capital. Over the past eight years, we have only raised $1.6 billion in equity, while at the same time invested over $6.5 billion into new streams and paid over $800 million in dividends.”

Financial Review

Revenues

Revenue was $212 million in the second quarter of 2018, on sales volume of 6.0 million ounces of silver and 87,100 ounces of gold. This represents a 6% increase from the $200 million of revenue generated in the second quarter of 2017 due primarily to (i) a 21% increase in the number of gold ounces sold; (ii) a 3% increase in the average realized gold price ($1,305 in Q2 2018 compared with $1,263 in Q2 2017); partially offset by (iii) a 6% decrease in the number of silver ounces sold; and (iv) a 3% decrease in the average realized silver price ($16.52 in Q2 2018 compared with $17.09 in Q2 2017).

Costs and Expenses

Average cash costs¹ in the second quarter of 2018 were $4.54 per silver ounce sold and $407 per gold ounce sold, as compared with $4.51 per silver ounce and $393 per gold ounce during the comparable period of 2017. This resulted in a cash operating margin¹ of $11.98 per silver ounce sold and $898 per gold ounce sold, a decrease of 5% per silver ounce sold and an increase of 3% per ounce of gold sold as compared with Q2 2017. The decrease in the silver cash operating margin was primarily due to a 3% decrease in the average realized silver price in Q2 2018 compared with Q2 2017 while the increase in the gold cash operating margin was primarily due to a 3% increase in the average realized gold price during the same period.

Earnings and Operating Cash Flows

Adjusted net earnings¹ and cash flow from operations in the second quarter of 2018 were $73 million ($0.16 per share) and $135 million ($0.31 per share¹), compared with adjusted net earnings¹ of $67 million ($0.15 per share) and cash flow from operations of $125 million ($0.28 per share¹) for the same period in 2017, an increase of 9% and 8%, respectively.

Balance Sheet

At June 30, 2018, the Company had approximately $93 million of cash on hand and $957 million outstanding under the Company’s $2 billion revolving term loan (the “Revolving Facility”). Subsequent to June 30, 2018, the Company used its Revolving Facility to fund the $500 million for the acquisition of the stream on Stillwater.

Second Quarter Asset Highlights

During the second quarter of 2018, attributable production was 6.1 million ounces of silver and 85,300 ounces of gold, representing a decrease of 15% and an increase of 7%, as compared with the second quarter of 2017.

Operational highlights for the quarter ended June 30, 2018, based upon counterparties’ reporting, are as follows:

- 3 -

Salobo

In the second quarter of 2018, Salobo produced 63,900 ounces of attributable gold, an increase of approximately 11% relative to the second quarter of 2017 as higher recovery and throughput were partially offset by lower grades. The Salobo plant operated at 100% of capacity in the quarter.

Peñasquito

In the second quarter of 2018, Peñasquito produced 1.3 million ounces of attributable silver, a decrease of approximately 15% relative to the second quarter of 2017 due to lower production from the oxide heap leach. According to Goldcorp Inc.’s (“Goldcorp”) second quarter of 2018 MD&A, lower production was a result of the planned transition from high-grade ore in Phase 5D at the bottom of the Peñasco pit, to lower grade ore from stockpiles and the remnants of Phase 5D. Production in Phase 5D was reportedly completed during the second quarter of 2018, and equipment was refocused on accelerating stripping activities in Phase 6D and in the Chile Colorado pit.

According to Goldcorp, construction of the Pyrite Leach Project (“PLP”) at Peñasquito has been completed with commissioning further accelerated to the third quarter of 2018, now two quarters ahead of schedule. As a result, Goldcorp has modified the production plan for the third quarter with lower than planned mill throughput and low mill head grades, exclusively from the surface stockpile, to accommodate the commissioning of a new major circuit, which is the preferred material to be processing during the commissioning phase where lower recoveries are expected. Goldcorp further notes that a resequencing to higher grades and mill tonnage in the fourth quarter, subsequent to the commissioning, is expected to allow the mine to meet its full year gold production objectives.

Antamina

In the second quarter of 2018, Antamina produced 1.5 million ounces of attributable silver, a decrease of approximately 23% relative to the second quarter of 2017 as expected due to mine sequencing in the open pit.

San Dimas

In the second quarter of 2018, San Dimas produced 5,700 ounces of attributable gold and 0.6 million ounces of attributable silver. On May 10, 2018, First Majestic announced that they had completed the previously announced acquisition of Primero. In connection with this acquisition, Wheaton International terminated the existing San Dimas silver purchase agreement with Primero (the “Primero SPA”) and entered into a new precious metals purchase agreement with First Majestic relating to the San Dimas mine (the “San Dimas PMPA”). Attributable silver production in the quarter was in relation to the Primero SPA, and attributable gold production was attributable to the San Dimas PMPA. Under the San Dimas PMPA, Wheaton is entitled to 25% of gold production plus an additional amount of gold equal to 25% of silver production converted to gold at a fixed gold to silver exchange ratio of 70:1 from the San Dimas mine², and for each ounce of gold delivered, Wheaton will pay to First Majestic a delivery payment equal to the lesser of $600/oz, subject to a 1% annual inflationary adjustment, and the prevailing market price. First Majestic has provided a corporate guarantee and security limited to San Dimas assets. As part of the transaction, in addition to the new stream, Wheaton received 20,914,590 First Majestic common shares with a fair value of $151 million. As reflected in the Company’s second quarter financial results, the termination of the Primero SPA has resulted in a gain on disposal of $246 million to Wheaton.

Sudbury

In the second quarter of 2018, Vale’s Sudbury mines produced 4,900 ounces of attributable gold, a decrease of approximately 34% relative to the second quarter of 2017 primarily due to lower grades and throughput. According to Vale’s second quarter of 2018 MD&A, the Coleman mine was in a maintenance shutdown from November 2017 to April 2018.

- 4 -

Constancia

In the second quarter of 2018, Constancia produced 0.6 million ounces of attributable silver and 3,200 ounces of attributable gold, an increase of approximately 9% and 37%, respectively, relative to the second quarter of 2017. Increased silver and gold production was primarily due to higher throughput and grades.

Other Silver

In the second quarter of 2018, total Other Silver attributable production was 2.2 million ounces, a decrease of approximately 6% relative to the second quarter of 2017. The decrease was driven primarily by the cessation of attributable production from the Lagunas Norte, Veladero, and Pierina mines as the silver purchase agreement with Barrick Gold Corp. (“Barrick”) related to these mines expired on March 31, 2018.

Other Gold

In the second quarter of 2018, total Other Gold attributable production was 7,500 ounces, a decrease of approximately 39% relative to the second quarter of 2017. The decrease was due primarily to lower production at both the Minto and 777 mines.

Produced But Not Yet Delivered ³

As at June 30, 2018, payable ounces attributable to the Company produced but not yet delivered³ amounted to 4.3 million payable silver ounces and 75,600 payable gold ounces, representing a decrease of 0.6 million payable silver ounces and 6,400 payable gold ounces during the three month period ended June 30, 2018. Payable silver ounces produced but not yet delivered decreased primarily as a result of decreases related to the San Dimas and Peñasquito silver interests partially offset by an increase related to the Yauliyacu silver interest. Payable gold ounces produced but not yet delivered decreased primarily as a result of a decrease related to the Salobo gold interest partially offset by increases related to the San Dimas and 777 gold interests. Payable ounces produced but not yet delivered to the Wheaton group of companies are expected to average approximately two months of annualized production for silver and two to three months for gold but may vary from quarter to quarter due to a number of mining operation factors including mine ramp-up and timing of shipments.

Detailed mine-by-mine production and sales figures can be found in the Appendix to this press release and in Wheaton’s consolidated MD&A in the ‘Results of Operations and Operational Review’ section.

Voisey’s Bay

On June 28, 2018, the Company entered into an agreement to acquire from Vale an amount of cobalt equal to 42.4% of the Voisey’s Bay cobalt production until the delivery of 31 million pounds of cobalt and 21.2% of cobalt production thereafter for the life of mine at a fixed 93.3% payable rate for a total upfront cash payment of $390 million. In addition, Wheaton will make delivery payments of 18% of the Metal Bulletin market price of cobalt (“cobalt spot price”) per pound of cobalt delivered under the agreement until such time as the upfront cash payment is reduced to zero, after which the per pound price paid will be 22% of the cobalt spot price per cobalt pound delivered. Delivery of cobalt production will commence after January 1, 2021.

- 5 -

Subsequent to the Quarter

Stillwater

On July 25, 2018, Wheaton International entered into an agreement to acquire from Sibanye-Stillwater an amount of gold and palladium equal to a fixed percentage of gold and palladium production from Stillwater starting on July 1, 2018. Wheaton International has paid a total upfront cash payment of $500 million and is entitled to an amount of gold equal to 100% of Stillwater gold production for the life of mine and an amount of palladium equal to: 4.5% of Stillwater palladium production until 375,000 ounces are delivered; thereafter, 2.25% of Stillwater palladium production until 550,000 are delivered; and 1% of Stillwater palladium production thereafter for the life of mine. In addition, Wheaton International will generally make delivery payments of 18% of spot gold and palladium prices until such time as the upfront cash payment is reduced to zero, after which the delivery payments will increase to 22% spot.

Acquisition of Adventus Shares

On July 17, 2018, the Company acquired 7,093,392 common shares of Adventus in a private placement transaction, for a total purchase price of Cdn$6 million, representing 9.99% of Adventus’ issued and outstanding common shares. Concurrently, the Company acquired a right of first refusal on any new streaming or royalty transactions on precious metals on the Adventus existing properties in Ecuador and a right of first offer on any subsequently acquired properties in Ecuador.

Dividend

Third Quarterly Dividend

The third quarterly cash dividend for 2018 of US$0.09 will be paid to holders of record of Wheaton Precious Metals common shares as of the close of business on August 29, 2018 and will be distributed on or about September 13, 2018.

The declaration, timing, amount and payment of future dividends remain at the discretion of the Board of Directors. This dividend qualifies as an ‘eligible dividend’ for Canadian income tax purposes.

Dividend Reinvestment Plan

The Company has previously implemented a Dividend Reinvestment Plan (“DRIP”). Participation in the DRIP is optional.

Outlook – Reconfirming Guidance

Wheaton reconfirms its estimated attributable production forecast for 2018 of approximately 355,000 ounces of gold, 22.5 million ounces of silver, and 10,400 ounces of palladium. Estimated average annual attributable production over the next five years (including 2018) is anticipated to be approximately 385,000 ounces of gold, 25 million ounces of silver, 27,000 ounces of palladium, and starting in 2021, 2.1 million pounds of cobalt per year. As a reminder, Wheaton does not include any production from Barrick’s Pascua-Lama project or Hudbay’s Rosemont project in its estimated average five-year production guidance.

From a liquidity perspective, the $93 million of cash and cash equivalents as at June 30, 2018 combined with the liquidity provided by the available credit under the $2 billion Revolving Facility and ongoing operating cash flows positions the Company well to fund all outstanding commitments and known contingencies as well as providing flexibility to acquire additional accretive precious metal stream interests.

Non-IFRS Measures

Wheaton Precious Metals has included, throughout this document, certain non-IFRS performance measures, including (i) adjusted net earnings and adjusted net earnings per share; (ii) operating cash flow per share (basic and diluted); (iii) average cash costs of silver and gold on a per ounce basis and; (iv) cash operating margin.

i. Adjusted net earnings and adjusted net earnings per share are calculated by removing the effects of the non-cash impairment charges, non-cash derivative (gains) losses, non-cash share of losses of associates and other one-time (income) fees. The Company believes that, in addition to conventional measures prepared in accordance with IFRS, management and certain investors use this information to evaluate the Company’s performance.

The following table provides a reconciliation of adjusted net earnings and adjusted net earnings per share (basic and diluted).

	Three Months Ended June 30
(in thousands, except for per share amounts)	2018			2017
Net earnings	$	318,142		$	67,612
Add back (deduct):
Gain on disposal of San Dimas SPA		(245,715	)		—
Loss on fair value adjustment of Kutcho Convertible Note		283			—
Loss on fair value adjustment of share purchase warrants held		12			—
Fees for contract amendments and reconciliations		—			(988	)
Adjusted net earnings	$	72,722		$	66,624
Divided by:
Basic weighted average number of shares outstanding		443,191			441,784
Diluted weighted average number of shares outstanding		443,770			442,370
Equals:
Adjusted earnings per share - basic	$	0.16		$	0.15
Adjusted earnings per share - diluted	$	0.16		$	0.15

- 16 -

ii. Operating cash flow per share (basic and diluted) is calculated by dividing cash generated by operating activities by the weighted average number of shares outstanding (basic and diluted). The Company presents operating cash flow per share as management and certain investors use this information to evaluate the Company’s performance in comparison to other companies in the precious metal mining industry who present results on a similar basis.

The following table provides a reconciliation of operating cash flow per share (basic and diluted).

	Three Months Ended June 30
(in thousands, except for per share amounts)	2018		2017
Cash generated by operating activities	$	135,200	$	124,681
Divided by:
Basic weighted average number of shares outstanding		443,191		441,784
Diluted weighted average number of shares outstanding		443,770		442,370
Equals:
Operating cash flow per share – basic	$	0.31	$	0.28
Operating cash flow per share – diluted	$	0.30	$	0.28

iii. Average cash cost of silver and gold on a per ounce basis is calculated by dividing the total cost of sales, less depletion, by the ounces sold. In the precious metal mining industry, this is a common performance measure but does not have any standardized meaning. In addition to conventional measures prepared in accordance with IFRS, management and certain investors use this information to evaluate the Company’s performance and ability to generate cash flow.

The following table provides a reconciliation of average cash cost of silver and gold on a per ounce basis.

	Three Months Ended June 30
(in thousands, except for gold ounces sold and per ounce amounts)	2018			2017
Cost of sales	$	125,074		$	116,753
Less: depletion		(62,494	)		(59,772	)
Cash cost of sales	$	62,580		$	56,981
Cash cost of sales is comprised of:
Total cash cost of silver sold	$	27,107		$	28,711
Total cash cost of gold sold		35,473			28,270
Total cash cost of sales	$	62,580		$	56,981
Divided by:
Total silver ounces sold		5,972			6,369
Total gold ounces sold		87,140			71,965
Equals:
Average cash cost of silver (per ounce)	$	4.54		$	4.51
Average cash cost of gold (per ounce)	$	407		$	393

- 17 -

iv. Cash operating margin is calculated by subtracting the average cash cost of silver and gold on a per ounce basis from the average realized selling price of silver and gold on a per ounce basis. The Company presents cash operating margin as management and certain investors use this information to evaluate the Company’s performance in comparison to other companies in the precious metal mining industry who present results on a similar basis as well as to evaluate the Company’s ability to generate cash flow.

The following table provides a reconciliation of cash operating margin.

	Three Months Ended June 30
(in thousands, except for gold ounces sold and per ounce amounts)	2018			2017
Total sales:
Silver	$	98,647		$	108,814
Gold	$	113,753		$	90,870
Divided by:
Total silver ounces sold		5,972			6,369
Total gold ounces sold		87,140			71,965
Equals:
Average realized price of silver (per ounce)	$	16.52		$	17.09
Average realized price of gold (per ounce)	$	1,305		$	1,263
Less:
Average cash cost of silver 1 (per ounce)	$	(4.54	)	$	(4.51	)
Average cash cost of gold 1 (per ounce)	$	(407	)	$	(393	)
Equals:
Cash operating margin per silver ounce sold	$	11.98		$	12.58
As a percentage of realized price of silver		73%			74%
Cash operating margin per gold ounce sold	$	898		$	870
As a percentage of realized price of gold		69%			69%

1) Please refer to non-IFRS measure (ii), above.

These non-IFRS measures do not have any standardized meaning prescribed by IFRS, and other companies may calculate these measures differently. The presentation of these non-IFRS measures is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. For more detailed information, please refer to Wheaton Precious Metals’ MD&A available on the Company’s website at www.wheatonpm.com and posted on SEDAR at www.sedar.com.

Cautionary Language Regarding Reserves And Resources

For further information on Mineral Reserves and Mineral Resources and on Wheaton more generally, readers should refer to Wheaton’s Annual Information Form for the year ended December 31, 2017 and other continuous disclosure documents filed by Wheaton since January 1, 2018, available on SEDAR at www.sedar.com. Wheaton’s Mineral Reserves and Mineral Resources are subject to the qualifications and notes set forth therein. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability.

Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Resources: The information contained herein has 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 Standards”). These definitions differ from the definitions in Industry Guide 7 (“SEC Industry Guide 7”) under the U.S. Securities Act of 1933, as amended (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. Accordingly, information contained herein that describes Wheaton’s mineral deposits may not be comparable to similar information made public by U.S. companies subject to reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder. United States investors are urged to consider closely the disclosure in Wheaton’s Form 40-F, a copy of which may be obtained from Wheaton or from http://www.sec.gov/edgar.shtml.

Overview

Wheaton Precious Metals Corp. is a mining company which generates its revenue from the sale of precious metals. The Company is listed on the New York Stock Exchange (“NYSE”) and the Toronto Stock Exchange (“TSX”) and trades under the symbol WPM.

Currently, the Company has entered into 23 long-term agreements (three of which are early deposit agreements), with 16 different mining companies, for the purchase of precious metals and cobalt (“precious metal purchase agreements” or “PMPA”) relating to 19 mining assets which are currently operating and 9 which are at various stages of development, located in 11 countries. Pursuant to the precious metal purchase agreements, 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. Attributable metal production as referred to in this MD&A and financial statements is the metal production to which Wheaton is entitled pursuant to the various precious metal purchase agreements. During the three months ended June 30, 2018, the per ounce price paid by the Company for the metals acquired under the agreements averaged $4.54 for silver and $407 for gold. The primary drivers of the Company’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 the sale of the metals received.

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [3]

Highlights

Operations

• The decrease in attributable silver production and the increase in attributable gold production for the three months ended June 30, 2018 was primarily due to the termination of the San Dimas silver stream effective May 10, 2018 and, concurrently, entering into a new San Dimas gold stream (see below), with the silver production being further impacted by the expiry of the streaming agreement relative to the Lagunas Norte, Veladero, and Pierina mines on March 31, 2018 and lower production at Antamina primarily due to lower silver grades resulting from mine sequencing in the open pit.

• The decrease in attributable silver production for the six months ended June 30, 2018 was primarily due to lower production at Antamina due to lower silver grades resulting from mine sequencing in the open pit.

• The increase in attributable gold production for the six months ended June 30, 2018 was primarily due to the acquisition of the new gold stream at San Dimas, as discussed below, coupled with higher production at Salobo, partially offset by lower production at Minto and Sudbury.

• The decrease in silver sales volume for the three months ended June 30, 2018 was due to the lower production levels, partially offset by positive changes in the balance of payable silver produced but not yet delivered to Wheaton, while the increase in silver sales volume for the six months ended June 30, 2018 was due to positive changes in the balance of payable silver produced but not yet delivered to Wheaton, partially offset by lower production levels.

• The increase in gold sales volume for the three months ended June 30, 2018 was primarily the result of the increased production levels coupled with positive changes in the balance of payable gold produced but not yet delivered to Wheaton, while the decrease in gold sales volume for the six months ended June 30, 2018 was due to relative changes in the balance of payable gold produced but not yet delivered to Wheaton coupled with lower production levels.

• During the second quarter ended June 30, 2018, the Company declared dividends in the amount of $40 million. On August 14, 2018, the Board of Directors declared a dividend in the amount of $0.09 per common share

Corporate Development

• On May 10, 2018, First Majestic Silver Corp. (“First Majestic”) announced that they had closed the previously announced acquisition of Primero Mining Corp. (“Primero”). In connection with this acquisition, on May 10, 2018, the Company terminated the previously owned San Dimas silver purchase agreement (the “San Dimas SPA”), resulting in a gain on disposal of $246 million, and concurrently entered into a new San Dimas precious metal purchase agreement (the “San Dimas PMPA”) with First Majestic for a total upfront cash payment of $220 million. Under the terms of the new 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.¹

• On June 11, 2018, the Company entered into an agreement to acquire from Vale S.A. (“Vale”) an amount of cobalt equal to 42.4% of the Voisey’s Bay cobalt production until the delivery of 31 million pounds of cobalt and 21.2% of cobalt production thereafter for the life of mine at a fixed 93.3% payable rate for a total upfront cash payment of $390 million. In addition, Wheaton will make ongoing payments of 18% of the spot price of cobalt per pound of cobalt delivered under the agreement until the upfront cash payment is reduced to $NIL, and 22% thereafter. Deliveries under the contract are scheduled to begin effective January 1, 2021.

• On July 16, 2018, the Company entered into an agreement to acquire from Sibanye Gold Limited (“Sibanye”) an amount of gold equal to 100% of the Stillwater mine gold production for life of mine and an amount of palladium equal to 4.5% of the Stillwater mine palladium production, decreasing to 2.25% and then 1% based upon defined delivery thresholds, for life of mine at fixed payable rates of 99.0% for gold and 99.6% for palladium for a total upfront cash payment of $500 million. The Company will generally make ongoing payments of 18% of spot gold and palladium prices until such time as the upfront cash payment is reduced to $NIL, and 22% thereafter.

• On July 17, 2018, the Company acquired 7,093,392 common shares of Adventus Zinc Corporation (“Adventus”) in a private placement transaction for total consideration of Cdn$6 million, representing 9.99% of Adventus’ issued and outstanding common shares. Concurrently, the Company paid an additional Cdn$1 million to acquire a right of first refusal on any new streaming or royalty transactions on precious metals on the Adventus existing properties in Ecuador and a right of first offer on any subsequently acquired properties in Ecuador.

¹  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.

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [4]

Outlook¹

Wheaton’s estimated attributable production in 2018 is forecast to be approximately 355,000 ounces of gold, 22.5 million ounces of silver and 10,400 ounces of palladium. Estimated average annual attributable production over the next five years (including 2018) is anticipated to be approximately 385,000 ounces of gold, 25 million ounces of silver, 27,000 ounces of palladium and, starting in 2021, 2.1 million pounds of cobalt per year. As a reminder, Wheaton does not include any production from Barrick’s Pascua-Lama project or Hudbay’s Rosemont project in its estimated average five-year production guidance.

From a liquidity perspective, the $93 million of cash and cash equivalents as at June 30, 2018 combined with the liquidity provided by the available credit under the $2 billion revolving term loan (“Revolving Facility”) and ongoing operating cash flows positions the Company well to fund all outstanding commitments and known contingencies as well as providing flexibility to acquire additional accretive mineral stream interests.

Silver Interests

San Dimas

On October 15, 2004, the Company entered into an agreement with Goldcorp to acquire an amount equal to 100% of the silver produced by Goldcorp’s Luismin mining operations in Mexico, including the San Dimas mine. On August 6, 2010, Goldcorp completed the sale of San Dimas to Primero Mining Corp. (“Primero”), and pursuant to the amended silver purchase agreement with Primero (the “San Dimas SPA”), the Company acquired 100% of the payable silver produced at San Dimas up to 6 million ounces annually, and 50% of any excess for the life of the mine. Goldcorp also provided a guarantee with respect to the delivery by Primero of all silver produced and owing to the Company until 2029 (the “Goldcorp Guarantee”).

On May 10, 2018, First Majestic Silver Corp. (“First Majestic”) announced that they had completed the previously disclosed acquisition of all the issued and outstanding common shares of Primero (the “Acquisition”). In connection with the Acquisition, on May 10, 2018, the Company terminated the previously owned San Dimas SPA and entered into a new precious metal purchase agreement with First Majestic relating to the San Dimas mine (the “San Dimas PMPA”) (see page 9 of this MD&A).

Through May 10, 2018, being the date of termination, the Company received approximately 82.1 million ounces of silver related to the San Dimas mine under the agreement, generating cumulative operating cash flows of approximately $1,119 million.

As consideration for terminating the San Dimas SPA, the Company received a cash payment of $220 million and 20,914,590 First Majestic common shares with a fair value of $151 million (the “First Majestic Shares¹”), and the Goldcorp Guarantee was terminated in exchange for a payment of $10 million, with the net result being that the Company has reflected a gain on disposal of the San Dimas SPA in the amount of $246 million, calculated as follows:

(in thousands)
Cash received	$	220,000
Fair value of First Majestic shares received		151,000
Fee from Goldcorp in exchange for release from the guarantee of deliveries relative to San Dimas		10,000
Total net proceeds from the disposal of the San Dimas SPA	$	381,000
Less: carrying value plus closing costs		(135,285	)
Gain on disposal of the San Dimas SPA	$	245,715

Peñasquito

On July 24, 2007, the Company entered into an agreement with Goldcorp Inc. (“Goldcorp”) to acquire an amount equal to 25% of the silver produced from Goldcorp’s Peñasquito mining operations (the “Peñasquito mine”) in Mexico for the life of mine, with the first deliveries under the agreement being received in September 2008.

According to Goldcorp, construction of the Pyrite Leach Project (“PLP”) at Peñasquito has been completed with commissioning further accelerated to the third quarter of 2018, now two quarters ahead of schedule. With the commissioning schedule of the PLP accelerated into the third quarter of 2018, Goldcorp has modified the production plan for the third quarter with lower than planned mill throughput and low mill head grades, exclusively from the surface stockpile, to accommodate the commissioning of a new major circuit, which is the preferred material to be processing during the commissioning phase where lower recoveries are expected. Goldcorp further notes that a resequencing to higher grades and mill tonnage in the fourth quarter, subsequent to the commissioning, is expected to allow the mine to meet its full year gold production objectives.

As at June 30, 2018, the Company has received approximately 45.6 million ounces of silver related to the Peñasquito mine under the agreement, generating cumulative operating cash flows of approximately $802 million, with approximately 0.3 million ounces of cumulative payable silver ounces having been produced at Peñasquito but not yet delivered to the Company, representing a 0.4 million ounce decrease during the three month period ended June 30, 2018.²

¹  The First Majestic Shares represent approximately 11% of First Majestic’s current issued and outstanding shares and are subject to resale restrictions, including a six month hold period (subject to certain exceptions) with volume selling restrictions thereafter.

²  Payable silver and gold ounces produced but not yet delivered are based on management estimates, and may be updated in future periods as additional information is received.

2) Please refer to the section entitled “Other Contractual Obligations and Contingencies” on page 30 of this MD&A for details of when the remaining upfront consideration to be paid becomes due.

3) Glencore will deliver a per annum amount to Wheaton equal to the first 1.5 million ounces of payable silver produced at Yauliyacu and 50% of any excess.

4) 95% owned by Eldorado Gold Corporation (“Eldorado”).

5) As per Capstone Mining Corp’s (“Capstone”) news release dated February 2, 2018, Capstone has agreed to sell its Minto mine to Pembridge Resources plc (“Pembridge”). As per Capstone’s news release dated July 11, 2018, Capstone expects the transaction to close in the third quarter of 2018.

6) Wheaton only has the rights to silver contained in concentrate containing less than 15% copper at the Aljustrel mine.

7) The upfront consideration is net of the $373 million cash flows received relative to silver deliveries from the Lagunas Norte, Veladero, and Pierina mines.

8) Wheaton and Pan American Silver Corp. (“PAAS”) have not yet finalized the definitive terms of the agreement.

As at June 30, 2018, the Company has received approximately 76.5 million ounces of silver under these agreements, generating cumulative operating cash flows of approximately $1.1 billion, with approximately 1.9 million ounces of cumulative payable silver ounces having been produced at the Other silver interests but not yet delivered to the Company, representing a 0.1 million ounce increase during the three month period ended June 30, 2018. ¹

As at December 31, 2017², unless otherwise noted, the Company’s share of proven and probable silver reserves relative to these Other silver interests was 262.5 million ounces, measured and indicated silver resources was 697.4 million ounces and inferred silver resources was 203.1 million ounces (as described in the Attributable Reserves and Resources section of this MD&A).

Gold Interests

Salobo

On February 28, 2013, the Company entered into an agreement to acquire from Vale S.A. (“Vale”) an amount of gold equal to 25% of the life of mine gold production from its currently producing Salobo mine, located in Brazil. On March 2, 2015 and August 2, 2016, respectively, the Company agreed to make two separate amendments to the agreement, ultimately increasing the gold stream from the original 25% to 75% of the life of mine gold production from Salobo.

The mill throughput at Salobo currently has a nameplate capacity of 24 million tonnes per annum (“Mtpa”), with the potential to further increase throughput beyond 24 Mtpa. If throughput capacity is expanded within a predetermined period, and depending on the grade of material processed, the Company will be required to make an additional payment to Vale, relative to the 75% stream, based on a set fee schedule ranging from $113 million if throughput is expanded beyond 28 Mtpa by January 1, 2036, to up to $953 million if throughput is expanded beyond 40 Mtpa by January 1, 2021. There will be no additional deposit due if the expansion is completed after January 1, 2036. Any further future increase in mill throughput at the Salobo mine is expected to allow the Company to enhance its production growth profile and benefit from any future exploration successes at the Salobo mine.

As of June 30, 2018, the Company has received approximately 751,500 ounces of gold related to the Salobo mine under the agreement, generating cumulative operating cash flows of approximately $637 million, with approximately 42,700 ounces of cumulative payable gold ounces having been produced at Salobo but not yet delivered to the Company, representing a 9,800 ounce decrease during the three month period ended June 30, 2018. ¹

¹  Payable silver and gold ounces produced but not yet delivered are based on management estimates, and may be updated in future periods as additional information is received.

²  Mineral reserves and mineral resources are reported as of December 31, 2017, other than as disclosed in footnote 6 to the Attributable Reserves and Resources tables on page 40 of this MD&A.

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [8]

As at December 31, 2017, the Company’s 75% share of the Salobo proven and probable gold reserves was 9.2 million ounces, measured and indicated gold resources was 1.6 million ounces and inferred gold resources was 1.2 million ounces (as described in the Attributable Reserves and Resources section of this MD&A).

Sudbury

On February 28, 2013, the Company entered into an agreement to acquire from Vale an amount of gold equal to 70% of the gold production from certain of its Sudbury mines located in Canada for a period of 20 years, including the currently operating Coleman, Copper Cliff, Garson, Creighton and Totten mines, the non-operating Victor project and the Stobie mine which was placed into care and maintenance during the second quarter of 2017.

As of June 30, 2018, the Company has received approximately 161,700 ounces of gold related to the Sudbury mines under the agreement, generating cumulative operating cash flows of approximately $138 million, with approximately 11,100 ounces of cumulative payable gold ounces having been produced at Sudbury but not yet delivered to the Company, representing an 300 ounce decrease during the three month period ended June 30, 2018.¹

As at December 31, 2017, the Company’s 70% share of the Sudbury mines proven and probable gold reserves was 570,000 ounces, measured and indicated gold resources was 50,000 ounces and inferred gold resources was 130,000 ounces (as described in the Attributable Reserves and Resources section of this MD&A).

Constancia

On November 4, 2013, the Company amended the Constancia PMPA to include the acquisition of an amount equal to 50%² of the life of mine gold production from Constancia, with the first deliveries under the agreement being received in April 2015. Should Hudbay fail to achieve a minimum level of throughput at the Pampacancha deposit during 2018, 2019 and 2020, Wheaton will be entitled to an increased portion of gold from Hudbay.

As per Hudbay’s news release dated March 26, 2018, although negotiations to secure surface rights over the Pampacancha deposit continue to progress and Hudbay has been granted access to the land to carry out early-works activities, they anticipate mining of this high-grade satellite deposit to commence in 2019, a one-year delay. In the interim, Hudbay will reportedly continue to mine higher-grade ore from the main Constancia pit. As the mining of the Pampacancha deposit has been delayed beyond 2018, Wheaton will be entitled to an increased portion of gold from Hudbay starting in 2019. Based on the current market price of gold, the additional deliveries due in 2019 will have a net value to the Company of approximately $6 million.

As at June 30, 2018, the Company has received approximately 39,900 ounces of gold related to the Constancia mine under the agreement, generating cumulative operating cash flows of approximately $33 million, with approximately 1,600 ounces of cumulative payable gold ounces having been produced at Constancia but not yet delivered to the Company, representing a 700 ounce increase during the three month period ended June 30, 2018. ¹

As at December 31, 2017, the Company’s 50% share of the Constancia proven and probable gold reserves was 530,000 ounces, measured and indicated gold resources was 250,000 ounces and inferred gold resources was 40,000 ounces (as described in the Attributable Reserves and Resources section of this MD&A).

San Dimas

On May 10, 2018, the Company entered into an agreement to with First Majestic to purchase an amount of gold equal to 25% of the life of mine payable gold production from San Dimas plus an additional amount of gold equal to 25% of the life of mine payable silver production from San Dimas converted to gold at a fixed gold to silver exchange ratio of 70:1.³

The company paid a total upfront cash payment of $220 million and, in addition, will make ongoing payments of $600 per gold ounce delivered.

As at June 30, 2018, the Company has received approximately 3,700 ounces of gold related to the San Dimas mine under the agreement, generating cumulative operating cash flows of approximately $2 million, with approximately 2,000 ounces of cumulative payable gold ounces having been produced at San Dimas but not yet delivered to the Company.¹

¹  Payable silver and gold ounces produced but not yet delivered are based on management estimates, and may be updated in future periods as additional information is received.

²  Gold recoveries will be set at 55% for the Constancia deposit and 70% for the Pampacancha deposit until 265,000 ounces of gold have been delivered to the Company.

³  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.

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [9]

As at December 31, 2017, the Company’s share of the San Dimas proven and probable gold and silver reserves was 120,000 ounces of gold and 9.9 million ounces of silver, measured and indicated resources of 70,000 ounces of gold and 4.6 million ounces of silver, and inferred resources of 200,000 ounces of gold and 17.7 million ounces of silver (as described in the Attributable Reserves and Resources section of this MD&A). As described above, attributable silver production will be delivered to the Company as gold, with the number of gold ounces to be delivered to be determined by converting silver production to gold at a fixed gold to silver exchange ratio of 70:1.¹

Mexican Tax Update

In February 2016, Primero announced that its Mexican subsidiary, Primero Empresa Minera S.A. de C.V. (“PEM”), received a legal claim from the Mexican tax authorities, Servicio de Administración Tributaria (“SAT”), seeking to nullify the Advance Pricing Agreement issued by SAT in 2012 (“2012 APA”). The 2012 APA confirmed Primero’s ability to pay taxes in Mexico on the sale of silver on actual prices realized by its Mexican subsidiary in connection with silver sales under the San Dimas SPA for the tax years 2010 through 2014. As disclosed by First Majestic in their MD&A for the period ended June 30, 2018, if the SAT is successful in retroactively nullifying the 2012 APA, the SAT may seek to audit and reassess Primero’s Mexican subsidiary in respect of sales of silver in connection with the San Dimas SPA for the tax years 2010 through 2014 and tax Primero on such sales at higher-than-realized prices, as opposed to the actual realized prices set under the San Dimas SPA. First Majestic indicates that if the SAT is successful in retroactively nullifying the APA and issuing reassessments, it would likely have a material adverse effect on First Majestic’s results of operations, financial condition and cash flows. PEM would have rights of appeal in connection with any reassessments.

First Majestic also stated that that in June 2017 and October 2017, the SAT issued two observation letters for the 2010 tax year and the 2011 tax year that made explicit its view that PEM should pay taxes based on the higher-than-realized prices, which if applied would make PEM liable for an additional $9 million in taxes before penalties or interest for the 2010 taxation year and $23 million for the 2011 taxation year. First Majestic also indicates that since they continue to defend the APA in the Mexican legal proceeding, the APA remains valid and First Majestic will vigorously dispute any reassessment that may be issued in the future on a basis that assesses taxes on PEM’s historical silver revenues that is inconsistent with the APA. The observation letters do not represent a tax reassessment and based on First Majestic’s assessments, they believe Primero’s filings were appropriate and continue to believe its tax filing position based upon the APA is correct. However, they note that should PEM ultimately be required to pay tax on its silver revenues based on market prices without any mitigating adjustments, the incremental income tax for the years 2012-2017 would be in the range of $130 - $145 million, before interest or penalties.

To the extent that First Majestic is not able to defend the validity of the 2012 APA or the SAT determines that the appropriate price to tax sales under the former San Dimas SPA or the new San Dimas PMPA is significantly different from the actual realized prices thereunder, it may have an adverse impact on First Majestic’s business, financial condition or results of operations.

Risks to Wheaton Precious Metals

If the Company was unable to purchase any further silver or gold under San Dimas PMPA, its reserves and resources would be significantly reduced, and the Company’s average five year forecasted silver equivalent production for 2018-2022 would be lowered by 5%, leading to a corresponding reduction to its revenue, net earnings and cash flows.

Stillwater

On July 16, 2018, the Company entered into an agreement with Sibanye Gold Limited (“Sibanye”) to acquire an amount of gold equal to 100% of the life of mine gold production from the Stillwater and East Boulder mines located in Montana in the United States (collectively referred to as the “Stillwater” mines) for a total upfront cash payment of $238 million. Deliveries under the agreement will begin July 1, 2018 at a fixed payable rate of 99%.

In addition to the initial upfront cash consideration, the Company will make ongoing payments of 18% of the spot price of gold for each ounce of gold delivered under the agreement until the upfront cash payment is reduced to $NIL and 22% of the spot price thereafter².

As at December 31, 2017, the Company’s share of the Stillwater proven and probable gold reserves was 410,000 ounces and inferred resources was 920,000 ounces (as described in the Attributable Reserves and Resources section of this MD&A).

¹  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.

²  The production payment is subject to further downward adjustment based upon Sibanye’s leverage ratios.

The Company’s long-term investments in common shares (“LTI’s”) are held for long-term strategic purposes and not for trading purposes. 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.

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 Unrealized Fair Value Losses (Gains). 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.

Acquisitions of Long-Term Investments

In connection with the disposal of the San Dimas SPA (see page 6 of this MD&A), on May 10, 2018 the Company received 20,914,590 First Majestic common shares with a fair value of $151 million¹.

¹  The First Majestic Shares represent approximately 11% of First Majestic’s current issued and outstanding shares and are subject to resale restrictions, including a six month hold period (subject to certain exceptions) with volume selling restrictions thereafter.

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [13]

Disposal of Long-Term Investments

As announced by Arizona Mining Inc. and South32 Limited on August 10, 2018, South32 has completed its acquisition of all of the issued and outstanding common shares of Arizona Mining. As a result, subsequent to June 30, 2018, the Company has disposed of its investment in Arizona Mining and will receive cash consideration for its investment in accordance with the terms of the acquisition.

Investment in Associate

Kutcho

Effective December 14, 2017, in connection with the Kutcho Early Deposit Agreement, the Company participated in an equity financing undertaken by Kutcho acquiring, by way of private placement, 6,153,846 common shares and warrants to acquire an additional 3,076,923 common shares of Kutcho for total consideration of $3 million (Cdn$4 million). Additionally, the Company advanced to Kutcho $16 million (Cdn$20 million) in exchange for a subordinated secured convertible term debt loan agreement receivable bearing interest at 10% per annum (the “Kutcho Convertible Note”).

As at January 31, 2018, Kutcho had 47,770,378 shares issued and outstanding, resulting in Wheaton owning approximately 13% of Kutcho on a non-diluted basis. However, as the convertible instruments described above are currently exercisable, on a fully diluted basis, Wheaton has the potential to own approximately 36% of Kutcho (45% on a non-fully diluted basis). As a result of the potential ownership position, the Company has concluded that it has significant influence over Kutcho and as such the investment in Kutcho is considered an Investment in Associate which is accounted for using the equity method. The Company records its share of Kutcho’s profit or loss based on Wheaton’s ownership interest in Kutcho on a non-diluted basis. As Kutcho’s fiscal year end is April 30, Wheaton has reported its share of Kutcho’s loss relative to Kutcho’s third quarter ended January 31, 2018, which represents the last period publicly reported by Kutcho as at the date of this MD&A.

A summary of the carrying value of the Kutcho Investment in Associate and the losses recognized as a component of the Company’s net earnings during 2018 is presented below:

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 has the option to defer the first three interest payments until December 31, 2019, at which point one half of the deferred interest is payable in cash and the other half of the deferred interest can, at Kutcho’s option, either (i) be paid in cash; or (ii) be deferred for an additional period not to exceed 4 years. In the event Kutcho elects to make the second deferral, Wheaton can, at its option, convert the remaining deferred interest into common shares of Kutcho.

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 into common shares of Kutcho at Cdn$0.8125 per share. Once the Kutcho Convertible Note has been outstanding for 24 months, Kutcho has the right to repay the Kutcho Convertible Note early, subject to the applicable pre-payment cash penalties as follows:

• 25% of the outstanding amount if pre-paid on or after 24 months until 36 months;

• 20% of the outstanding amount if pre-paid on or after 36 months until 60 months; and

• 15% of the outstanding amount if pre-paid on or after 60 months until maturity.

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.

A summary of the fair value of the Kutcho Convertible Note and the fair value changes recognized as a component of the Company’s net earnings during the three and six months ended June 30, 2018 is presented below:

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [20]

Silver Production

For the three months ended June 30, 2018, attributable silver production was 6.1 million ounces relative to 7.2 million ounces for the comparable period in 2017, with the 1.1 million ounce decrease being primarily attributable to the following factors:

• 430,000 ounce (23%) decrease related to the silver stream at the Antamina mine, which was expected and is primarily due to mine sequencing in the open pit;

• 365,000 ounce (38%) decrease related to the silver stream at the San Dimas mine, resulting from the termination of the San Dimas SPA effective May 10, 2018, as more fully explained on page 6 of the MD&A;

• 216,000 ounce (15%) decrease related to the silver stream at the Peñasquito mine, resulting from the lower production from the oxide heap leach; and

• 140,000 ounce (6%) decrease related to silver production at the Other mines, primarily due to the expiry of the streaming agreement relative to the Lagunas Norte, Veladero, and Pierina mines on March 31, 2018.

Gold Production

For the three months ended June 30, 2018, attributable gold production was 85,300 ounces relative to 79,600 ounces for the comparable period in 2017, with the 5,700 ounce increase being primarily attributable to the following factors:

• 6,400 ounce (11%) increase related to the Salobo mine, due primarily to higher recoveries; and

• 5,700 ounce increase related to the recently acquired gold stream at the San Dimas mine, as more fully explained on pages 6 and 9 of this MD&A; partially offset by

• 4,800 ounce (39%) decrease related to gold production at the Other mines which was primarily due to lower grades and throughput at the Minto and 777 mines; and

• 2,600 ounce (34%) decrease related to the Sudbury mines which was primarily due to lower grades.

Net Earnings and Cash Flow from Operations

For the three months ended June 30, 2018, the net earnings and cash flow from operations were $318 million and $135 million, respectively, relative to $68 million and $125 million, respectively, for the comparable period in 2017, with the $250 million increase in net earnings being primarily attributable to the following factors:

Changes relative to production of silver and gold:

• $9 million decrease related to a 19% decrease in payable silver ounces produced; and

• $5 million decrease related to the composition of mines from which silver and gold is produced; and

• $3 million increase related to a 7% increase in payable gold ounces produced.

Changes relative to silver and gold ounces produced but not yet delivered:

• $13 million increase as a result of the timing of shipments of stockpiled concentrate and doré.

Changes relative to other items:

• $246 million increase as a result of the gain on disposal of the previously owned silver stream relative to the San Dimas mine, as explained on page 6 of this MD&A;

• $3 million increase due to an increase in the operating margin per ounce;

• $3 million increase due to an increase in the income tax recovery during the current period, as more fully explained on page 27 of this MD&A; and

• $1 million increase as a result of a decrease in Interest Costs as explained on page 26 of this MD&A; partially offset by

• $3 million decrease as a result of an increase in General and Administrative expenses as explained on page 25 of this MD&A ($1 million decrease from a cash flow perspective).

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [23]

Silver Production

For the six months ended June 30, 2018, attributable silver production was 13.6 million ounces, relative to 13.8 million ounces for the comparable period in 2017, with the 0.2 million ounce decrease being primarily attributable to the following factors:

• 555,000 ounce (17%) decrease related to the silver stream at the Antamina mine, which was expected and is primarily due to mine sequencing in the open pit; and

• 362,000 ounce (7%) decrease related to silver production at the Other mines, due primarily to the expiry the streaming agreement relative to the Cozamin mine on April 4, 2017 and the expiry the streaming agreement relative to the Lagunas Norte, Veladero, and Pierina mines on March 31, 2018; partially offset by

• 618,000 ounce (39%) increase related to the previously owned silver stream at the San Dimas mine as production during the first half of 2017 was impacted by a strike initiated by the union at San Dimas on February 15, 2017.

Gold Production

For the six months ended June 30, 2018, attributable gold production was 162,000 ounces, relative to 163,400 ounces for the comparable period in 2017, with the 1,400 ounce decrease being primarily attributable to the following factors:

• 10,600 ounce (40%) decrease related to gold production at the Other mines, primarily due to lower production at the Minto mine as a result of lower grades; and

• 8,200 ounce (50%) decrease related to the Sudbury mines, primarily due to lower throughput and grades; partially offset by

• 9,900 ounce (9%) increase related to the Salobo mine, primarily due to higher throughput, grades and recoveries; and

• 5,700 ounce increase related to the recently acquired gold stream at the San Dimas mine, as more fully explained on pages 6 and 9 of this MD&A.

Net Earnings and Cash Flow from Operations

For the six months ended June 30, 2018, net earnings and cash flow from operations were $386 million and $261 million, respectively, relative to $129 million and $245 million, respectively, for the comparable period in 2017, with the $257 million increase in net earnings being primarily attributable to the following factors:

Changes relative to production of silver and gold:

• $4 million decrease related to a 4% decrease in payable silver ounces produced; and

• $1 million decrease related to the composition of mines from which silver and gold is produced; partially offset by

• $1 million decrease related to a 1% decrease in payable gold ounces produced.

Changes relative to silver and gold ounces produced but not yet delivered:

• $8 million increase as a result of the timing of shipments of stockpiled concentrate and doré.

Changes relative to other items:

• $246 million increase as a result of the gain on disposal of the previously owned silver stream relative to the San Dimas mine, as explained on page 6 of this MD&A;

• $11 million increase due to an increase in the operating margin per ounce, due primarily to a 7% increase in the average realized price per gold ounce sold and lower depletion rates per ounce of silver sold;

• $3 million increase due to an increase in the income tax recovery during the current period, as more fully explained on page 27 of this MD&A; and

• $2 million increase as a result of a decrease in Interest Costs as explained on page 26 of this MD&A; partially offset by

• $5 million decrease as a result of an increase in General and Administrative expenses as explained on page 25 of this MD&A (no change from a cash flow perspective); and

• $2 million decrease as a result of the change in fair value of the Kutcho convertible note receivable (no impact from a cash flow perspective) as explained on page 15 of this MD&A.

For the three and six months ended June 30, 2018, income tax recovery increased by $3 million relative to the comparable periods in the previous year, with the current period income tax recovery being primarily related to the recognition of capital losses to offset unrealized capital gains relating to the Company’s long-term equity investments. Offsetting the deferred income tax recovery in earnings is a deferred income tax expense of $4 million that has been recognized directly in OCI relating to the unrealized gains on long-term equity investments.

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [27]

Liquidity and Capital Resources¹

As at June 30, 2018, the Company had cash and cash equivalents of $93 million (December 31, 2017 - $99 million) and debt outstanding under its $2 billion revolving term loan (the “Revolving Facility”) of $957 million (December 31, 2017 - $770 million), resulting in a net debt position of $864 million (December 31, 2017 - $671million).

A summary of the Company’s cash flow activity is as follows:

Three Months Ended June 30, 2018

During the three months ended June 30, 2018, the Company generated operating cash flows of $135 million compared with $125 million during the comparable period of 2017.

During the three months ended June 30, 2018, the Company had net cash inflows from financing activities of $230 million, which was primarily the result of an advance in the amount of $373 million taken under the Company’s Revolving Facility which was used to partially fund the Voisey’s Bay cobalt stream, with this cash inflow being partially offset by repayments under the Company’s Revolving Facility in the amount of $79 million and dividend payments totaling $65 million. During the three months ended June 30, 2017, the Company had net cash outflows from financing activities of $163 million which was primarily the result of repayments under the Company’s Revolving Facility in the amount of $111 million and dividend payments totaling $52 million.

During the three months ended June 30, 2018, the Company had net cash outflows from investing activities of $388 million, which was primarily the result of (i) a payment to Vale in the amount of $390 million in connection with the Voisey’s Bay cobalt stream; (ii) a $220 million payment to First Majestic in connection with the San Dimas PMPA; (iii) a $4 million payment to Kutcho in connection with the Kutcho Early Deposit Agreement; and (iv) a $1 million payment to Panoro in connection with the Cotabambas Early Deposit Agreement; with these cash outflows being partially offset by a $220 million payment received from First Majestic as partial consideration for the termination of the previously owned San Dimas SPA and a $10 million payment received from Goldcorp as consideration for the termination of the Goldcorp Guarantee. During the three months ended June 30, 2017, the Company had virtually no cash flows from investing activities.

Six Months Ended June 30, 2018

During the six months ended June 30, 2018, the Company generated operating cash flows of $261 million compared with $245 million during the comparable period of 2017, with the increase being primarily related to the increase in the average realized price of gold.

During the six months ended June 30, 2018, the Company had net cash inflows from financing activities of $122 million, which was primarily the result of an advance in the amount of $373 million taken under the Company’s Revolving Facility which was used to partially fund the Voisey’s Bay cobalt stream, with this cash inflow being partially offset by repayments under the Company’s Revolving Facility in the amount of $186 million and dividend payments totaling $65 million. During the six months ended June 30, 2017, the Company had net cash outflows from financing activities of $292 million, which was primarily the result of repayments under the Company’s Revolving Facility in the amount of $240 million and dividend payments totaling $52 million.

During the six months ended June 30, 2018, the Company had net cash outflows from investing activities of $388 million, which was primarily the result of (i) a payment to Vale in the amount of $390 million in connection with the Voisey’s Bay cobalt stream; (ii) a $220 million payment to First Majestic in connection with the San Dimas PMPA; (iii) a $4 million payment to Kutcho in connection with the Kutcho Early Deposit Agreement; and (iv) a $1 million payment to Panoro in connection with the Cotabambas Early Deposit Agreement; with these cash outflows being partially offset by a $220 million payment received from First Majestic as partial consideration for the termination of the previously owned San Dimas SPA and a $10 million payment received from Goldcorp as consideration for the termination of the Goldcorp Guarantee. During the six months ended June 30, 2017, the Company had virtually no cash flows from investing activities.

In the opinion of management, the $93 million of cash and cash equivalents as at June 30, 2018, combined with the liquidity provided by the available credit under the $2 billion Revolving Facility and ongoing operating cash flows positions the Company well to fund the $500 million payment relative to the Stillwater PMPA, all other outstanding commitments and known contingencies as well as providing flexibility to acquire additional accretive mineral stream interests.

1) Subject to an annual inflationary adjustment with the exception of Loma de La Plata and Sudbury.

2) All amounts are measured on a per ounce basis with the exception of cobalt which is measured on a per pound basis. Should the prevailing market price for the applicable metal be lower than this amount, the per ounce or per pound 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 $4.35 per ounce, subject to an annual inflationary factor.

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.

4) The Company is committed to pay Glencore 20% of the spot price of silver for each ounce of silver delivered under the Antamina silver purchase agreement.

5) Gold recoveries will be set at 55% for the Constancia deposit and 70% for the Pampacancha deposit until 265,000 ounces of gold have been delivered to the Company.

6) Subject to an increase to $9.90 per ounce of silver and $550 per ounce of gold after the initial 40-year term.

7) 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 life of mine.

8) The Company is committed to pay Sabanye 18% of the spot price of gold and palladium for each ounce of gold and palladium delivered under the Stillwater precious metal purchase agreement until such time as the upfront cash payment is reduced to $NIL and 22% of the spot price thereafter.

9) Once the Company has received 31 million pounds of cobalt, the Company’s attributable cobalt production to be purchased will be reduced to 21.2%.

10) The Company is committed to pay Vale 18% of the spot price of cobalt per pound of cobalt delivered under the agreement until such time as the upfront cash payment is reduced to $NIL, and 22% of the spot price thereafter.

11) Wheaton is committed to purchase from Glencore a per annum amount equal to the first 1.5 million ounces of payable silver produced at Yauliyacu and 50% of any excess.

12) Should the market price of silver exceed $20 per ounce, in addition to the $8.85 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 $18.85 per ounce of silver delivered.

13) In October 2015, in order to incentivize additional exploration and potentially extend the limited remaining mine life of Stratoni, Wheaton and Eldorado Gold agreed to modify the Stratoni silver purchase agreement. The primary modification is to increase the production price per ounce of silver delivered to Wheaton over the current fixed price by one of the following amounts: (i) $2.50 per ounce of silver delivered if 10,000 meters of drilling is completed outside of the existing ore body and within Wheaton’s defined area of interest (“Expansion Drilling”); (ii) $5.00 per ounce of silver delivered if 20,000 meters of Expansion Drilling is completed; and (iii) $7.00 per ounce of silver delivered if 30,000 meters of Expansion Drilling is completed. Drilling in all three cases must be completed by December 31, 2020, in order for the agreed upon increase in production price to be initiated. The figures in the above table reflect the fact that Eldorado completed 10,000 meters of Expansion Drilling in July 2018.

14) The Company is committed to acquire 100% of the first 30,000 ounces of gold produced per annum and 50% thereafter.

15) The production payment per ounce of gold delivered to Wheaton is to be increased over the current fixed price in periods where the market price of copper is lower than $2.50 per pound.

16) Wheaton only has the rights to silver contained in concentrate containing less than 15% copper at the Aljustrel mine.

17) During the second quarter of 2018, the Company agreed to amend the precious metal purchase agreement with Almina to increase the production payments to 50% of the amount received under the respective concentrate sales contracts and to fix silver payable rates for a period of two years and limit rate decreases thereafter.

18) The production payment related to the Keno Hill silver interest is a function of the silver head grade and silver spot price in the month in which the silver is produced.

19) Terms of the agreement not yet finalized.

20) Once 90 million silver equivalent ounces attributable to Wheaton have been produced, the attributable production to be purchased will decrease to 66.67% of silver production and 16.67% of gold production for the life of mine.

21) 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 silver and gold production for the life of mine.

22) The Company is committed to pay Kutcho 20% of the spot price of silver and gold for each ounce of silver and gold delivered under the Kutcho Early Deposit Agreement.

If actual throughput is expanded above 28 Mtpa within a predetermined period, and depending on the grade of material processed, Wheaton will be required to make an additional payment to Vale based on a set fee schedule ranging from $113 million if throughput is expanded beyond 28 Mtpa by January 1, 2036, up to $953 million if throughput is expanded beyond 40 Mtpa by January 1, 2021.

Stillwater

On July 25, 2018, in connection with the Stillwater precious metal purchase agreement, the Company paid to Sibanye a total upfront cash payment of $500 million.

Taxes

2013 Taxation Year: Domestic

On July 24, 2018, the Company received a Notice of Reassessment for the 2013 taxation year (“the 2013 Domestic Reassessment”) 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 in respect of 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 basis over the estimated recoverable reserves, and where applicable, resources and exploration potential at the respective mine. The Company’s position, as reflected in its filed Canadian income tax returns, is 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, as provided for in the PMPAs.

Management believes the Company’s position is the correct one, and that it has filed its tax returns and paid applicable taxes in compliance with Canadian tax law. Wheaton intends to file a notice of objection within the 90-day period required under the Income Tax Act (Canada) (the “Act”) challenging the 2013 Domestic Reassessment. Even if the Company is unsuccessful in defending its position, it would not result in any additional tax for the 2013 taxation year after applying non-capital losses carried back from subsequent taxation years. However, interest and penalties of approximately $0.7 million (Cdn$0.9 million) remain owing (calculated to the date of the 2013 Domestic Reassessment), 50% of which must be paid in order to object to the 2013 Domestic Reassessment.

The CRA is conducting a domestic audit for the 2014 and 2015 taxation years. The 2016 and 2017 taxation years remain open to a domestic audit. If CRA were to reassess the Company’s Canadian PMPAs for the 2014-2017 taxation years on the same basis as CRA has reassessed the Company in the 2013 Domestic Reassessment, the Company estimates that it would not result in a material amount of additional tax, interest, and penalties.

2005 – 2010 Taxation Years: Canada Revenue Agency Dispute

On September 24, 2015, the Company received Notices of Reassessment (the “Reassessments”) from the CRA totaling $268 million (Cdn$353 million) for federal and provincial tax, transfer pricing penalties, interest and other penalties for the 2005-2010 taxation years. The CRA’s position in the Reassessments is that the transfer pricing provisions of the Act relating to income earned by the Company’s foreign subsidiaries outside of Canada should apply such that the income of Wheaton subject to tax in Canada should be increased by an amount equal to substantially all of the income earned outside of Canada by the Company’s foreign subsidiaries for the 2005-2010 taxation years. Management believes that the Company has filed its tax returns and paid applicable taxes in compliance with Canadian tax law, and as a result no amounts have been recorded for any potential liability arising from this matter. Wheaton is vigorously defending its tax filing positions.

On January 8, 2016, the Company commenced an appeal in the Tax Court of Canada. The Company was required to make a deposit of 50% of the reassessed amounts of tax, interest and penalties. Instead of making this deposit in cash, on March 15, 2016, the Company posted security in the form of a letter of guarantee in the amount of $146 million (Cdn$192 million), which included interest accrued to March 2016 plus estimated interest for the following year. In March 2017 and 2018, additional letters of guarantee in the amounts of $8 million (Cdn$11 million) and $8 million (Cdn$10 million), respectively, were delivered to the CRA as security for additional estimated interest for the respective following year. The Company is currently in the discovery phase of the appeal, with a trial scheduled to commence mid-September 2019 for a two month period.

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [31]

2011 – 2015 Taxation Years: Audit of International Transactions

The CRA has also commenced an audit of the Company’s international transactions covering the 2011-2015 taxation years, which is currently ongoing. The Company has not received any proposal or notices of reassessment for the 2011-2015 taxation years in connection with this audit.

For ease of reference, the following provides an overview of the current status of CRA matters relating to income earned by the Company’s foreign subsidiaries outside of Canada:

Taxation Years	CRA Position/Status	Potential Income Inclusion	Potential Income Tax Payable (1)	Payments Made	Timing
2005-2010	Transfer pricing provisions of the Act should apply such that Wheaton’s income subject to tax in Canada should be increased by an amount equal to substantially all of the income earned outside of Canada by Wheaton’s foreign subsidiaries.	CRA has reassessed Wheaton and is seeking to increase Wheaton’s income subject to tax in Canada by Cdn$715 million.	CRA has reassessed Wheaton and is seeking to impose income tax of $153 million (Cdn$201 million).(2),(3)	Wheaton has posted security in the form of letters of guarantee totaling $162 million (Cdn$213 million) reflecting 50% of all assessed tax, penalties and interest accrued to March 15, 2019.(3),(4)	An appeal in the Tax Court of Canada commenced January 8, 2016. Trial scheduled to commence mid-September 2019 for a two month period.
2011-2015	CRA commenced an audit of 2011-2015 taxation years. CRA has not issued a proposal or reassessment.	If CRA were to reassess on a similar basis as 2005-2010 taxation years, the Company estimates CRA would seek to increase Wheaton’s income subject to tax in Canada by approximately $1.9 billion.(5),(8)	If CRA were to reassess on a similar basis as 2005-2010 taxation years, the Company estimates CRA would seek to impose income tax of approximately $384 million (Cdn$505 million).(5),(6),(8)	N/A	Time to complete CRA audit unknown.
2016-2017	Remains open to audit by CRA.	If CRA were to audit and then reassess on a similar basis as 2005-2010 taxation years, the Company estimates CRA would seek to increase Wheaton’s income subject to tax in Canada by approximately $580 million.(5),(8)	If CRA were to reassess on a similar basis as 2005-2010 taxation years, the Company estimates CRA would seek to impose income tax of approximately $149 million (Cdn$197 million).(5),(7),(8)	N/A	N/A

1) For the taxation years ended after December 31, 2010, the Company files its Canadian tax returns in US dollars. However, taxes payable, if any, are payable in Canadian dollars based on the exchange rate applicable on the original payment due date. As a result, the US dollar amounts reflected in the table above are subject to fluctuations in the value of the Canadian dollar relative to the US dollar. Canadian dollar amounts in this table have been converted to US dollars at the exchange rate applicable at the balance sheet date as quoted by the Bank of Canada.

2) For the 2005-2010 taxation years, transfer pricing penalties of $54 million (Cdn$72 million) and interest and other penalties of $61 million (Cdn$81 million) were also assessed by the CRA. The total reassessment issued on September 24, 2015 was $268 million (Cdn$353 million). Additional interest accruing to December 31, 2017 on the total amount reassessed is estimated at $34 million (Cdn$45 million) for the 2005-2010 taxation years.

3) As a consequence of the CRA’s reassessment of the 2005-2010 taxation years and the 2013 Domestic Reassessment, CRA reassessed the 2011 and 2012 taxation years to amend the non-capital losses available to offset the taxable income of $12 million and $14 million, respectively. As a result of the 2013 Domestic Reassessment, additional tax, interest, and penalties of about $1.6 million (Cdn$2.2 million) was owing for the 2011 and 2012 taxation years. The Company will be filing Notices of Objection with respect to these reassessments and accordingly, the Company will be required to pay 50% of the additional amounts owing. These reassessments do not relate to the CRA international audit of the 2011-2015 taxation years.

4) Estimates of interest given as of the date stated. Interest accrues until payment date.

5) The estimates of income inclusion and tax payable are computed on the basis that the cost of precious metal acquired under the PMPAs is equal to the cash cost plus an amortized amount of the up-front payment and without taking into account any available Canadian non-capital losses.

6) If CRA were to reassess the 2011-2015 taxation years and continue to apply transfer pricing penalties, management estimates that transfer pricing penalties of approximately $187 million and interest (calculated to December 31, 2017) and other penalties of approximately $110 million (Cdn$145 million) may be applicable for the 2011-2015 taxation years.

7) If CRA were to reassess the 2016-2017 taxation years and continue to apply transfer pricing penalties, management estimates that transfer pricing penalties of approximately $58 million and interest (calculated to December 31, 2017) and other penalties of approximately $9 million (Cdn$12 million) may be applicable for the 2016-2017 taxation years.

8) If the cost of precious metal acquired under the PMPAs is equal to the market value of precious metal while the deposit is outstanding (where applicable to an agreement), and the cash cost thereafter, the estimated amounts for the 2011 – 2015 taxation years would be as follows: (i) income inclusion of $1.6 billion; (ii) tax payable of $331 million (Cdn$435 million); (iii) transfer pricing penalties (if applied) of $161 million; and (iv) interest and other penalties of $93 million (Cdn$123 million). On this basis, the estimated amounts for the 2016 – 2017 taxation years would be as follows: (i) income inclusion of $260 million; (ii) tax payable of $68 million (Cdn$89 million); (iii) transfer pricing penalties (if applied) of $26 million; and (iv) interest and other penalties of $4 million (Cdn$6 million).

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [32]

U.S. Shareholder Class Action

During July 2015, after the Company disclosed that the CRA was proposing that they would issue the Reassessments, two putative securities class action lawsuits were filed against the Company in the U.S. District Court for the Central District of California in connection with the Proposal (the “Complaints”).

On October 19, 2015, the Complaints were consolidated into one action, In re Silver Wheaton Securities Litigation, as against the Company, Randy Smallwood, President & Chief Executive Officer, Gary Brown, Senior Vice President & Chief Financial Officer and Peter Barnes, former Chief Executive Officer (together the “Defendants”) and a lead plaintiff (the “Plaintiff”) was selected. The Plaintiff filed a consolidated amended complaint in December 2015, and then filed a second amended complaint in April 2018 (the “Amended Complaint”). The Amended Complaint alleges, among other things, that the Defendants made false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, prospects and performance in violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Specifically, the Amended Complaint focuses on the Reassessments. The Amended Complaint purports to be brought on behalf of persons who purchased or otherwise acquired the Company’s securities in the United States during an alleged class period of March 30, 2011 to July 6, 2015.

At a hearing on June 6, 2016, the Court denied the Defendants’ motion to dismiss. A denial of such a motion is not a ruling on the merits of the claims in the lawsuit. Certification of the class was granted by the Court on May 11, 2017. Defendants have filed motions to dismiss the second amended complaint and a hearing is set for November 2018. No trial date is currently set for this matter.

The Company believes the allegations are without merit and intends to vigorously defend against this matter. No amounts have been recorded for any potential liability arising from this matter, as the original Complaints do not specify a quantum of damages and the Company cannot reasonably predict the outcome.

Canadian Shareholder Class Action

By Notice of Action dated August 10, 2016 (as amended September 2, 2016), 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 statement of claim filed alleges, among other things, misrepresentation pursuant to primary and secondary market civil liability provisions under the Securities Act (Ontario), common law negligence and negligent misrepresentation. The claim focuses on the Reassessments. The statement of claim purports to be brought on behalf of persons who (i) acquired Wheaton common shares in Wheaton’s March 2015 public offering, and (ii) acquired Wheaton common shares in the secondary market, other than in the United States, during an alleged class period of August 14, 2013 to July 6, 2015 inclusive.

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.

Please see “Cautionary Note Regarding Forward-Looking Statements” in the MD&A for material risks, assumptions and important disclosure associated with outstanding litigation.

Other¹

Due to the size, complexity and nature of the Company’s operations, various legal and tax matters are outstanding from time to time. 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.

¹  The assessment by management of the expected impact of the Reassessments on the Company is “forward-looking information”. Statements in respect of the impact of the Reassessments are based on the expectation that the Company will be successful in challenging the Reassessments by CRA. Statements in respect of the Reassessments and estimates of any future taxes that the CRA may assert are payable are subject to known and unknown risks including that the Company’s interpretation of, or compliance with, tax laws, is found to be incorrect. Please see “Cautionary Note Regarding Forward-Looking Statements” in the MD&A for material risks, assumptions and important disclosure associated with this information.

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [33]

Share Capital

During the three and six months ended June 30, 2018, the Company received cash proceeds of $1 million from the exercise of 46,800 share purchase options at a weighted average exercise price of $24.28 per option, with all exercises taking place during the three months ended June 30, 2018. During the three months ended June 30, 2017, the Company received cash proceeds of $0.2 million from the exercise of 13,000 share purchase options at a weighted average exercise price of Cdn$23.61 per option (six months - $1 million from the exercise of 53,050 share purchase options at a weighted average exercise price of Cdn$25.15).

As of August 14, 2018, there were 443,559,922 outstanding common shares, 3,887,850 share purchase options, 403,951 restricted share units and 10,000,000 share purchase warrants.

Financial Instruments

The Company owns equity interests in several mineral exploration, development and mining companies as long-term investments (see page 12 of this MD&A) in addition to the Kutcho Convertible Note (see page 15 of this MD&A) and therefore is inherently exposed to various risk factors including currency risk, market price risk and liquidity risk.

In order to mitigate the effect of short-term volatility in silver and gold prices, the Company will occasionally enter into forward contracts in relation to silver and gold deliveries that it is highly confident will occur within a given quarter. The Company does not hedge its long-term exposure to commodity prices. Other than these very short-term forward contracts, the Company has not used derivative financial instruments to manage the risks associated with its operations and therefore, in the normal course of business, it is inherently exposed to currency, interest rate and commodity price fluctuations. No forward contracts were outstanding at June 30, 2018.

New Accounting Standards Effective 2018

IFRS 9 – Financial Instruments (amended 2014):

On January 1, 2018, the Company adopted IFRS 9 (2014) – Financial Instruments (amended 2014) (“IFRS 9 (2014)”). The Company had previously adopted IFRS 9 (2009) – Financial Instruments effective January 1, 2010. The adoption of IFRS 9 (2014) did not materially impact the accounting policies and methods of application relative to the Company’s financial instruments.

IFRS 15 – Revenue from Contracts with Customers:

On January 1, 2018, the Company adopted IFRS 15 – Revenue from Contracts with Customers (“IFRS 15”) which supersedes IAS 18 – Revenue (“IAS 18”). IFRS 15 establishes a single five-step model framework for determining the nature, amount, timing and uncertainty of revenue and cash flows arising from a contract with a customer. The standard is effective for annual periods beginning on or after January 1, 2018. IFRS 15 requires entities to recognize revenue when ‘control’ of goods or services transfers to the customer whereas the previous standard, IAS 18, required entities to recognize revenue when the ‘risks and rewards’ of the goods or services transfer to the customer. The Company concluded that there is no change in the timing of revenue recognition of its silver and gold credit sales and its silver and gold concentrate sales under IFRS 15 compared to the previous standard as the point of transfer of risks and rewards of the silver and gold and the transfer of control of the silver and gold occur at the same time. As such, no adjustment was required to the Company’s consolidated financial statements as at January 1, 2017 or for the year ended December 31, 2017. Additionally, IFRS 15 requires that variable consideration should only be recognized to the extent that it is highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur. The Company concluded that the adjustments relating to the final assay results for the quantity of concentrate sold under the terms of the concentrate sales contracts are not significant and do not constrain the recognition of revenue.

Future Changes in Accounting Policies

The International Accounting Standards Board (“IASB”) has issued the following new or amended standards:

Standards required to be applied for periods beginning on or after January 1, 2019:

• IFRS 16 – Leases: In January 2016, the IASB and the FASB completed its joint project to address concerns by users of financial statements in respect of reduced comparability between financial statements due to the different accounting treatment applied to operating leases as compared to finance leases by removing the distinction between operating leases and finance leases and rather having all leases accounted for as a finance lease, subject to limited exceptions for short-term leases and leases of low value assets. The Company is currently evaluating the impact of this standard and anticipates that upon adoption of this standard, its leases will be capitalized under the classification Right-of-Use Assets, with a corresponding liability for Leases Payable. The total amount to be capitalized is estimated to be $3 million. The Company also expects a reduction in operating cash outflows of approximately $1 million per annum upon the adoption of IFRS 16, with a corresponding increase in financing cash outflows. Lastly, the Company does not anticipate the adoption of this standard will have a material impact on its Consolidated Statement of Earnings.

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [34]

• IFRIC 23 – Uncertainty over Income Tax Treatments: In June 2017, the IASB issued IFRIC 23 which is effective for periods beginning on or after January 1, 2019. IFRIC 23 provides guidance on the accounting for current and deferred tax liabilities and assets in circumstances in which there is uncertainty over income tax treatments. The extent of the impact of the adoption of IFRIC 23 has not yet been determined.

Early adoption of the above standards is permitted.

Non-IFRS Measures

Wheaton has included, throughout this document, certain non-IFRS performance measures, including (i) adjusted net earnings and adjusted net earnings per share; (ii) operating cash flow per share (basic and diluted); (iii) average cash costs of silver and gold on a per ounce basis; and (iv) cash operating margin.

i. Adjusted net earnings and adjusted net earnings per share are calculated by removing the effects of the non-cash impairment charges, non-cash fair value (gains) losses, non-cash share of losses of associates and other one-time (income) fees. The Company believes that, in addition to conventional measures prepared in accordance with IFRS, management and certain investors use this information to evaluate the Company’s performance.

The following table provides a reconciliation of adjusted net earnings and adjusted net earnings per share (basic and diluted).

	Three Months Ended June 30						Six Months Ended June 30
(in thousands, except for per share amounts)	2018			2017			2018			2017

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [35]

ii. Operating cash flow per share (basic and diluted) is calculated by dividing cash generated by operating activities by the weighted average number of shares outstanding (basic and diluted). The Company presents operating cash flow per share as management and certain investors use this information to evaluate the Company’s performance in comparison to other companies in the precious metal mining industry who present results on a similar basis.

The following table provides a reconciliation of operating cash flow per share (basic and diluted).

	Three Months Ended June 30				Six Months Ended June 30
(in thousands, except for per share amounts)	2018		2017		2018		2017
Cash generated by operating activities	$	135,200	$	124,681	$	260,540	$	244,604
Divided by:
Basic weighted average number of shares outstanding		443,191		441,784		442,961		441,635
Diluted weighted average number of shares outstanding		443,770		442,370		443,453		442,168
Equals:
Operating cash flow per share - basic	$	0.31	$	0.28	$	0.59	$	0.55
Operating cash flow per share - diluted	$	0.30	$	0.28	$	0.59	$	0.55

iii. Average cash cost of silver and gold on a per ounce basis is calculated by dividing the total cost of sales, less depletion, by the ounces sold. In the precious metal mining industry, this is a common performance measure but does not have any standardized meaning. In addition to conventional measures prepared in accordance with IFRS, management and certain investors use this information to evaluate the Company’s performance and ability to generate cash flow.

The following table provides a calculation of average cash cost of silver and gold on a per ounce basis.

	Three Months Ended June 30						Six Months Ended June 30

iv. Cash operating margin is calculated by subtracting the average cash cost of silver and gold on a per ounce basis from the average realized selling price of silver and gold on a per ounce basis. The Company presents cash operating margin as management and certain investors use this information to evaluate the Company’s performance in comparison to other companies in the precious metal mining industry who present results on a similar basis as well as to evaluate the Company’s ability to generate cash flow.

The following table provides a reconciliation of cash operating margin.

Subsequent Events

Declaration of Dividend

On August 14, 2018, the Board of Directors declared a dividend in the amount of $0.09 per common share as per the Company’s stated dividend policy whereby the quarterly dividend will be equal to 30% of the average of the operating cash flow of the previous four quarters. This dividend is payable to shareholders of record on August 29, 2018 and is expected to be distributed on or about September 13, 2018. 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 3% of the Average Market Price, as defined in the DRIP.

Acquisition of Stillwater Mineral Stream Interest

On July 16, 2018, the Company announced that it had entered into an agreement with Sibanye to acquire an amount of gold and palladium equal to a fixed percentage of production from the Stillwater and East Boulder mines located in Montana in the United States (collectively referred to as the “Stillwater” mines) for a total upfront cash payment of $500 million. Deliveries under the agreement will begin July 1, 2018 at a fixed payable rate of 99% for gold and 99.6% for palladium.

Under the terms of the agreement, the Company has acquired an amount of gold equal to 100% of the gold production for the life of the mine and an amount of palladium equal to 4.5% of the palladium production until 375,000 ounces of palladium have been delivered to Wheaton, after which the Company’s entitlement will be reduced to 2.25% of the palladium production until 550,000 ounces of palladium have been delivered to Wheaton, after which the Company’s entitlement will be reduced to 1.00% of the palladium production for the life of mine.

In addition to the initial upfront cash consideration, the Company will make ongoing payments of 18% of the spot price of gold and palladium for each ounce of gold and palladium delivered under the agreement until the net market value of gold and palladium delivered to Wheaton exceeds the initial upfront cash deposit, and 22% of the spot price thereafter¹.

Acquisition of Adventus Zinc Corporation Shares

On July 17, 2018, the Company acquired 7,093,392 common shares of Adventus in a private placement transaction, for total consideration of Cdn$6 million, representing 9.99% of Adventus’ issued and outstanding common shares. Concurrently, the Company paid an additional Cdn$1 million to acquire a right of first refusal on any new streaming or royalty transactions on precious metals on the Adventus existing properties in Ecuador and a right of first offer on any subsequently acquired properties in Ecuador.

Controls and Procedures

Disclosure Controls and Procedures

Wheaton’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, has evaluated the design and effectiveness of Wheaton’s disclosure controls and procedures, as defined in the rules of the U.S. Securities and Exchange Commission and Canadian Securities Administrators, as of June 30, 2018. Based on that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that Wheaton’s disclosure controls and procedures were effective at the reasonable assurance level as of June 30, 2018.

Internal Control Over Financial Reporting

The Company’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, are responsible for establishing and maintaining adequate internal control over financial reporting. Under the supervision of the Chief Financial Officer, the Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with IFRS. The Company’s controls include policies and procedures that:

• pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

• provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with IFRS, and that receipts and expenditures of the Company are being made only in accordance with authorizations of the Company’s management and directors; and,

• provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the annual financial statements or interim financial statements.

¹  The production payment is subject to further downward adjustment based upon Sibanye’s leverage ratios.

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [38]

There have been no changes in the Company’s internal control over financial reporting during the three months ended June 30, 2018 that would materially affect, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

The Company’s management, including its Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company’s internal control over financial reporting using the framework and criteria established in Internal Control – Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management has concluded that the internal control over financial reporting was effective at the reasonable assurance level as of June 30, 2018.

Limitation of Controls and Procedures

The Company’s management, including its Chief Executive Officer and Chief Financial Officer, believe that any disclosure controls and procedures or internal control over financial reporting, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, they cannot provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been prevented or detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by unauthorized override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Accordingly, because of the inherent limitations in a cost effective control system, misstatements due to error or fraud may occur and not be detected.

c. Constancia – Hudbay’s annual information form for the year ended December 31, 2017 filed on March 29, 2018.

The Company QP’s have approved this partner disclosed scientific and technical information in respect of the Peñasquito mine, Antamina mine and Constancia mine, as well as, the Company’s Mineral Resource and Mineral Reserve estimates for the Salobo mine.

11. The Company’s attributable Mineral Resources and Mineral Reserves for the Lagunas Norte, Veladero, and Antamina silver interests, Sudbury gold interests and Voisey’s Bay cobalt interests, have been constrained to the production expected for the various contracts.

12. The Antamina silver purchase agreement in respect to the Antamina mine (November 3, 2015) provides that Glencore will deliver 33.75% of the silver production until 140 million ounces are delivered and 22.5% of silver production thereafter, for a 50 year term that can be extended in increments of 10 years at the Company’s discretion. Attributable reserves and resources have been calculated on the 33.75% / 22.5% basis.

13. The Yauliyacu mine silver purchase agreement provides that Glencore will deliver to the Company a per annum amount equal to the first 1.5 million ounces of payable silver produced at the Yauliyacu mine and 50% of any excess for the life of the mine.

14. Effective May 10, 2018, First Majestic announced that they had closed the previously announced acquisition of Primero. In connection with this acquisition, the Company terminated the San Dimas SPA and entered into the San Dimas PMPA with First Majestic. 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.

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [44]

15. The Rosemont mine Mineral Resources and Mineral Reserves do not include the Oxide material.

16. On January 17, 2018, Chile’s Superintendencia del Medio Ambiente (SMA) ordered the closure of existing infrastructure on the Chilean side of the Pascua-Lama project. As a result, Barrick has reclassified Pascua-Lama’s proven and probable gold reserves as measured and indicated resources. As a result, Wheaton has also reclassified 151.7 million ounces of silver mineral reserves associated with Pascua-Lama as measured and indicated resources.

17. The Company only has the rights to silver contained in concentrates containing less than 15% copper at the Aljustrel mine.

18. The Company’s agreement with Panoro is an Early Deposit agreement, whereby the Company will be entitled to purchase 100% of the silver production and 25% of the gold production from the Cotabambas project until 90 million silver equivalent ounces have been delivered, at which point the stream will drop to 66.67% of silver production and 16.67% of gold production for the life of mine.

19. The Company’s agreement with Sandspring is an Early Deposit agreement, whereby the Company will be entitled to purchase 10% of the gold production and 50% of the silver production from the Toroparu project for the life of mine.

20. The Company’s agreement with Kutcho Copper is an Early Deposit agreement, whereby the Company will be entitled to purchase 100% of the silver and gold production from the Kutcho project until 5.6 million ounces of silver and 51,000 ounces of gold have been delivered, after which both streams will decrease to 66.67% for the remaining life of mine.

21. With respect to Early Deposit agreements, the Company has the option to terminate the agreement following the delivery of a feasibility study or if feasibility study has not been delivered within a required time frame.

22. Effective August 7, 2014, the Company entered into an agreement for a 1.5% net smelter returns royalty on Chesapeake Gold Corp.’s (Chesapeake) Metates property, located in Mexico. As part of the agreement, Chesapeake will have the right at any time for a period of five years to repurchase two-thirds of the royalty, with the Company retaining a 0.5% royalty interest.

23. The Voisey’s Bay cobalt purchase agreement provides that effective January 1, 2021, Vale will deliver 42.4% of the cobalt production until 31 million pounds are delivered to the Company and 21.2% of cobalt production thereafter, for the life of the mine. Attributable reserves and resources have been calculated on the 42.4% / 21.2% basis.

24. The Stillwater precious metal purchase agreement provides that effective July 1, 2018, Sibanye will deliver 100% of the gold production for the life of the mines and 4.5% of palladium production until 375,000 ounces are delivered, 2.25% of palladium production until a further 175,000 ounces are delivered and 1.0% of the palladium production thereafter for the life of the mines. Attributable palladium Mineral Reserves and Mineral Resources have been calculated based upon the 4.5% / 2.25% / 1.0% production entitlements.

25. The Stillwater mine has been in operation since 1986 and the East Boulder mine since 2002. Individual grades for platinum, palladium, gold and rhodium are estimated using ratios applied to the combined platinum plus palladium grades based upon average historic production results provided to the Company as of the date of this document. As such, the Attributable Mineral Resource and Mineral Reserve palladium and gold grades for the Stillwater mines have been estimated using the following ratios:

a. Stillwater mine: Pd = (Pt + Pd) / (1/3.51 + 1) and Au = (Pd + Pt) x 0.0153

b. East Boulder mine: Pd = (Pt + Pd) / (1/3.6 + 1) and Au = (Pd + Pt) x 0.0227

26. Silver, gold and cobalt subject to the precious metal purchase agreements are produced as by-product metal at all operations with the exception of silver at the Keno Hill mines and Loma de La Plata project and gold at the Toroparu project; therefore, the economic cut-off applied to the reporting of silver, gold and cobalt Mineral Resources and Mineral Reserves will be influenced by changes in the commodity prices of other metals at the time of reporting.

Cautionary Language Regarding Reserves And Resources

For further information on Mineral Reserves and Mineral Resources and on Wheaton more generally, readers should refer to Wheaton’s Annual Information Form for the year ended December 31, 2017 and other continuous disclosure documents filed by Wheaton since January 1, 2018, available on SEDAR at www.sedar.com. Wheaton’s Mineral Reserves and Mineral Resources are subject to the qualifications and notes set forth therein. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability.

Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Resources: The information contained herein has 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 Standards”). These definitions differ from the definitions in Industry Guide 7 (“SEC Industry Guide 7”) under the U.S. Securities Act of 1933, as amended (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. Accordingly, information contained herein that describes Wheaton’s mineral deposits may not be comparable to similar information made public by U.S. companies subject to reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder. United States investors are urged to consider closely the disclosure in Wheaton’s Form 40-F, a copy of which may be obtained from Wheaton or from http://www.sec.gov/edgar.shtml.

Including the agreements entered into after June 30, 2018 (Note 27), the Company has entered into 23 long-term purchase agreements (three of which are early deposit agreements), with 16 different mining companies, for the purchase of precious metals and cobalt (“precious metal purchase agreements” or “PMPA”) relating to 19 mining assets which are currently operating and 9 which are at various stages of development, located in 11 countries. Pursuant to the precious metal purchase agreements, Wheaton acquires metal production from the counterparties for an initial upfront payment plus an additional cash payment for each ounce 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, 2018 were authorized for issue as of August 14, 2018 in accordance with a resolution of the Board of Directors.

2. Basis of Presentation

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”). 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, 2017 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, 2017.

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, 2018 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.

3. Significant Accounting Policies

3.1. New Accounting Standards Effective in 2018

IFRS 9 – Financial Instruments (amended 2014):

On January 1, 2018, the Company adopted IFRS 9 (2014) – Financial Instruments (amended 2014) (“IFRS 9 (2014)”). The Company had previously adopted IFRS 9 (2009) – Financial Instruments effective January 1, 2010. The adoption of IFRS 9 (2014) did not materially impact the accounting policies and methods of application relative to the Company’s financial instruments.

IFRS 15 – Revenue from Contracts with Customers:

On January 1, 2018, the Company adopted IFRS 15 – Revenue from Contracts with Customers (“IFRS 15”) which supersedes IAS 18 – Revenue (“IAS 18”). IFRS 15 establishes a single five-step model framework for determining the nature, amount, timing and uncertainty of revenue and cash flows arising from a contract with a customer. The standard is effective for annual periods beginning on or after January 1, 2018. IFRS 15 requires entities to recognize revenue when ‘control’ of goods or services transfers to the customer whereas the previous standard, IAS 18, required entities to recognize revenue when the ‘risks and rewards’ of the goods or services transfer to the customer.

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [56]

Notes to the Condensed Interim Consolidated Financial Statements

Three and Six Months Ended June 30, 2018 (US Dollars - Unaudited)

The Company concluded that there is no change in the timing of revenue recognition of its silver and gold credit sales and its silver and gold concentrate sales under IFRS 15 compared to the previous standard as the point of transfer of risks and rewards of the silver and gold and the transfer of control of the silver and gold occur at the same time. As such, no adjustment was required to the Company’s consolidated financial statements as at January 1, 2017 or for the year ended December 31, 2017. Additionally, IFRS 15 requires that variable consideration should only be recognized to the extent that it is highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur. The Company concluded that the adjustments relating to the final assay results for the quantity of concentrate sold under the terms of the concentrate sales contracts are not significant and do not constrain the recognition of revenue.

3.2. Future Changes in Accounting Policies

The IASB has issued the following new or amended standards:

Standards required to be applied for periods beginning on or after January 1, 2019:

• IFRS 16 – Leases: In January 2016, the IASB and the FASB completed its joint project to address concerns by users of financial statements in respect of reduced comparability between financial statements due to the different accounting treatment applied to operating leases as compared to finance leases by removing the distinction between operating leases and finance leases and rather having all leases accounted for as a finance lease, subject to limited exceptions for short-term leases and leases of low value assets. The Company is currently evaluating the impact of this standard and anticipates that upon adoption of this standard, its leases will be capitalized under the classification Right-of-Use Assets, with a corresponding liability for Leases Payable. The total amount to be capitalized is estimated to be $3 million. The Company also expects a reduction in operating cash outflows of approximately $1 million per annum upon the adoption of IFRS 16, with a corresponding increase in financing cash outflows. Lastly, the Company does not anticipate the adoption of this standard will have a material impact on its Consolidated Statement of Earnings.

• IFRIC 23 – Uncertainty over Income Tax Treatments: In June 2017, the IASB issued IFRIC 23 which is effective for periods beginning on or after January 1, 2019. IFRIC 23 provides guidance on the accounting for current and deferred tax liabilities and assets in circumstances in which there is uncertainty over income tax treatments. The extent of the impact of the adoption of IFRIC 23 has not yet been determined.

Early adoption of the above standards is permitted.

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 $5.8 billion at June 30, 2018. 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 precious metal purchase agreements. 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 precious metal purchase agreements. 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.

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [57]

Notes to the Condensed Interim Consolidated Financial Statements

Three and Six Months Ended June 30, 2018 (US Dollars - Unaudited)

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 judgement 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 basis over the estimated recoverable proven and probable reserves at the mine corresponding to the specific agreement. The value associated with resources and exploration potential is the value beyond proven and probable reserves at acquisition and is classified as non-depletable until such time as it is transferred to the depletable category as a result of the conversion of resources and/or exploration potential into reserves. To make this allocation, the Company estimates the recoverable reserves, resources and exploration potential at each mining operation. These calculations require the use of estimates and assumptions, including the amount of contained metals, recovery rates and payable rates. Changes to these assumptions may impact the estimated recoverable reserves, resources or exploration potential which could directly impact the depletion rates used. Changes to depletion rates are accounted for prospectively.

4.3. Impairment of Assets

The Company assesses each precious metal purchase agreement 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 precious metal purchase agreement 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 silver and gold has been extremely volatile over the past several years and should price levels decline in the future for an extended period of time, the Company may need to re-evaluate the long-term metal price assumptions used for impairment testing. A significant decrease in long-term metal price assumptions may be an indication of potential impairment. Should the Company conclude that it has an indication of impairment at any balance sheet date, the Company is required to perform an impairment assessment.

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 20.2, 20.3, and 21.1, respectively.

4.5. Valuation of Convertible Note Receivable

As more fully described in Note 16, the Company measures its convertible note receivable with Kutcho Copper Corp. at fair value for financial reporting purposes. This calculation requires the use of estimates and assumptions such as rate of interest prevailing at the balance sheet date for instruments of similar term and risk, expected dividend yield, expected volatility and expected remaining life of the convertible note receivable.

4.6. Valuation of Minto Derivative Liability

As more fully described in Note 5.3, the Company’s Minto precious metal purchase agreement has a pricing mechanism whereby there is an increase to the production payment per ounce of gold delivered to Wheaton over the current fixed price in periods where the market price of copper is lower than $2.50 per pound. As this pricing mechanism meets the definition of a derivative, it is reflected at fair value for financial reporting purposes. This calculation requires the use of estimates and assumptions such as long-term price of copper, recoverable ounces of gold and operating performance.

4.7. 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

4.8. 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.

4.9. Significant Influence over Kutcho

Note 15 describes Kutcho Copper Corp. (“Kutcho”) as an associate though the Company only owns a 13% ownership interest in Kutcho. The Company has determined it has significant influence over Kutcho by virtue of the convertible instruments of Kutcho that the Company owns.

4.10. 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 shipments of metals 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 and 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 estimates and assumptions are consistent with those used in testing asset impairment of precious metal purchase agreements. The amount of deferred income tax assets recognized on the balance sheet could be reduced if the actual results differ significantly from forecast. The Company reassesses its deferred income tax assets at the end of each reporting period.

5. Fair Value Measurements

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.

Other accounts receivables and accounts payables and accrued liabilities are non-interest bearing and are stated at carrying values, which approximate fair values due to the short terms to maturity. Where necessary, other receivables are reported net of allowances for uncollectable amounts.

The Company’s bank debt (Note 18.1) is reported at amortized cost using the effective interest method. The carrying value of the bank debt approximates its fair value.

5.1. 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.

5.2. 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 silver and gold 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.

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [60]

Notes to the Condensed Interim Consolidated Financial Statements

Three and Six Months Ended June 30, 2018 (US Dollars - Unaudited)

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.

5.3. Valuation Techniques for Level 3 Assets

Convertible Note Receivable

The fair value of the Kutcho Convertible Note receivable (Note 16), 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 Kutcho Convertible Note receivable.

As the expected volatility and market interest rate are not observable inputs, the Kutcho 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 Unrealized Fair Value Losses (Gains), Net (Note 10).

Management estimates that the market interest rate on similar borrowings without the conversion feature was approximately 15% and has used an implied volatility of 30% in valuing the convertibility feature. If (i) the market interest rate used had been 2% lower or higher at the respective balance sheet date; or (ii) the implied volatility used had been 10% higher or lower at the respective balance sheet date, then the value of the Kutcho Convertible Note receivable would have increased or decreased by approximately $1 million.

Minto Derivative Liability

In October 2017, in order to incentivize Capstone Mining Corp. to extend the Minto mine life, the Company agreed to amend the Minto precious metal purchase agreement. The primary modification is to increase the production payment per ounce of gold delivered to Wheaton over the current fixed price in periods where the market price of copper is lower than $2.50 per pound. As this pricing mechanism meets the definition of a derivative, it is reflected at fair value for financial reporting purposes. At June 30, 2018 and December 31, 2017, the Company estimated the fair value of this derivative liability to be $NIL as the long-term outlook for copper based on a consensus derived from a number of sources including analysts and other market observers exceeds $2.50 per pound over the duration of the anticipated remaining mine life.

WHEATON PRECIOUS METALS 2018 SECOND QUARTER REPORT [61]

Notes to the Condensed Interim Consolidated Financial Statements

Three and Six Months Ended June 30, 2018 (US Dollars - Unaudited)

Silver and Gold Credit Sales

Under certain precious metal purchase agreements, silver and/or gold is acquired from the mine operator in the form of silver or gold credits, which is then sold through a network of third party brokers or dealers. Revenue from silver and gold credit sales is recognized at the time of the sale of such credits, which is also the date that control of the silver or gold is transferred to the customer.

The Company will occasionally enter into forward contracts in relation to silver or gold deliveries that it is highly confident will occur within a given quarter. No forward contracts were outstanding at June 30, 2018 or December 31, 2017. 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 silver or gold.

Concentrate Sales

Under certain precious metal purchase agreements, silver and/or gold 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 silver or gold in concentrate form, final silver or gold 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 silver or gold. The contracts, in general, provide for a provisional payment based upon provisional assays and quoted silver and gold prices. Final settlement is based upon the average applicable price for the Quotational Period applied to the actual number of silver or gold 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 buyer, which is also the date that control of the silver or gold 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.

2) On March 29, 2017, the Company amended its silver purchase agreement with Alexco Resource Corp. (“Alexco”) to adjust the silver production payment so that it will be a percentage of the spot silver price that increases with lower mill silver head grades and lower silver prices, and decreases with higher mill silver head grades and higher silver prices, subject to certain ceiling and floor grades and prices. In addition, the outside completion date was extended to December 31, 2019 and the area of interest was expanded to include properties currently owned by Alexco and properties acquired by Alexco in the future which fall within a one kilometer radius of existing Alexco holdings in the Keno Hill Silver District. As consideration, on April 10, 2017, Alexco issued 3 million shares to Wheaton which had a fair value of $5 million. The fair value of these shares have been reflected as a reduction to the cost base of the Keno Hill silver interest.

3) Comprised of the Los Filos, Zinkgruvan, Yauliyacu, Stratoni, Keno Hill, Cozamin, Neves-Corvo, Minto, Aljustrel, Loma de La Plata, Pascua-Lama, Lagunas Norte, Pierina, Veladero, Rosemont and 777 silver interests. The Cozamin precious metal purchase agreement expired on April 4, 2017 and the fully depleted value of this contract has been reflected as a disposal.

The value allocated to reserves is classified as depletable upon a mining operation achieving first production and is depleted on a unit-of-production basis over the estimated recoverable proven and probable reserves at the mine. The value associated with resources and exploration potential is allocated at acquisition and is classified as non-depletable until such time as it is transferred to the depletable category, generally as a result of the conversion of resources or exploration potential into reserves.

Termination of the San Dimas Silver Interest and Acquisition of the San Dimas Gold Interest

On October 15, 2004, the Company entered into an agreement with Goldcorp Inc. (“Goldcorp”) to acquire an amount equal to 100% of the silver produced by Goldcorp’s Luismin mining operations in Mexico, including the San Dimas mine. On August 6, 2010, Goldcorp completed the sale of San Dimas to Primero Mining Corp. (“Primero”), and pursuant to the amended silver purchase agreement with Primero (the “San Dimas SPA”), the Company acquired 100% of the payable silver produced at San Dimas up to 6 million ounces annually, and 50% of any excess for the life of the mine. Goldcorp also provided a guarantee with respect to the delivery by Primero of all silver produced and owing to the Company until 2029 (the “Goldcorp Guarantee”).

On May 10, 2018, First Majestic completed the previously disclosed acquisition of all the issued and outstanding common shares of Primero (the “Acquisition”). In connection with the Acquisition, on May 10, 2018, the Company terminated the San Dimas SPA and entered into a new precious metal purchase agreement with First Majestic relating to the San Dimas mine (the “San Dimas PMPA”). As consideration for terminating the San Dimas SPA, the Company received a cash payment of $220 million and 20,914,590 First Majestic common shares with a fair value of $151 million (the “First Majestic Shares¹”), and the Goldcorp Guarantee was terminated in exchange for a payment of $10 million, with the net result being that the Company has reflected a gain on disposal of the San Dimas SPA in the amount of $246 million, calculated as follows:

¹  The First Majestic Shares represent approximately 11% of First Majestic’s current issued and outstanding shares and are subject to resale restrictions, including a six month hold period (subject to certain exceptions) with volume selling restrictions thereafter.

Under the terms of the new San Dimas PMPA, for which the Company paid total upfront cash consideration of $220 million, 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 70:1.¹ In addition to the $220 million upfront cash payment, the Company will make ongoing payments of $600 per gold ounce delivered.

Acquisition of the Voisey’s Bay Cobalt Interest

On June 11, 2018, the Company entered into an agreement to acquire from Vale S.A. (“Vale”) an amount of cobalt equal to 42.4% of the cobalt production from its Voisey’s Bay mine, located in Canada, until the delivery of 31 million pounds of cobalt and 21.2% of cobalt production thereafter for the life of mine for a total upfront cash payment of $390 million. In addition, Wheaton will make ongoing payments of 18% of the spot price of cobalt per pound of cobalt delivered under the agreement until such time as the upfront cash payment is reduced to $NIL and 22% of the spot price of cobalt thereafter. Payable rates for cobalt in concentrate have generally been fixed at 93.3%. Deliveries under the contract are scheduled to begin effective January 1, 2021.

13. 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:

	Mine Owner										Attributable Production to be Purchased
Early Deposit Mineral Stream Interests			Location of Mine		Upfront Consideration Paid to Date 1		Upfront Consideration to be Paid 1, 2		Total Upfront Consideration¹		Silver			Gold			Term of Agreement

1) Expressed in United States dollars, rounded to the nearest thousand; excludes closing costs.

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 to be purchased will decrease to 66.67% of silver production and 16.67% of gold 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 silver and gold production for the life of mine.

¹  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.

14. Mineral Royalty Interest

On August 7, 2014, the Company purchased a 1.5% net smelter return royalty interest (the “Royalty”) in the Metates properties located in Mexico from Chesapeake Gold Corp. (“Chesapeake”) for the life of mine. Under the terms of the agreement, the Company paid total upfront cash consideration of $9 million and at any time prior to August 7, 2019, Chesapeake may reacquire two-thirds ( ²⁄₃) of the Royalty, or 1%, for the sum of $9 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 this royalty agreement.

15. Investment in Associate

Kutcho

Effective December 14, 2017, in connection with the Kutcho Early Deposit Agreement (Note 13), the Company participated in an equity financing undertaken by Kutcho Copper Corp. (“Kutcho”) acquiring, by way of private placement, 6,153,846 common shares and warrants to acquire an additional 3,076,923 common shares of Kutcho for total consideration of $3 million (Cdn$4 million). Additionally, the Company advanced to Kutcho $16 million (Cdn$20 million) in exchange for a subordinated secured convertible term debt loan agreement receivable bearing interest at 10% per annum (the “Kutcho Convertible Note”) (see Note 16).

As at January 31, 2018, Kutcho had 47,770,378 shares issued and outstanding, resulting in Wheaton owning approximately 13% of Kutcho on a non-diluted basis. However, as the convertible instruments described above are currently exercisable, on a fully diluted basis, Wheaton has the potential to own approximately 36% of Kutcho (45% on a non-fully diluted basis). As a result of the potential ownership position, the Company has concluded that it has significant influence over Kutcho and as such the investment in Kutcho is considered an Investment in Associate which is accounted for using the equity method. The Company records its share of Kutcho’s profit or loss based on Wheaton’s ownership interest in Kutcho on a non-diluted basis. As Kutcho’s fiscal year end is April 30, Wheaton has reported its share of Kutcho’s loss relative to Kutcho’s third quarter ended January 31, 2018, which represents the last period publicly reported by Kutcho as at the date these financial statements were authorized for issue.

16. Convertible Note Receivable

Kutcho

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 has the option to defer the first three interest payments until December 31, 2019, at which point one half of the deferred interest is payable in cash and the other half of the deferred interest can, at Kutcho’s option, either (i) be paid in cash; or (ii) be deferred for an additional period not to exceed 4 years. In the event Kutcho elects to make the second deferral, Wheaton can, at its option, convert the remaining deferred interest into common shares of Kutcho.

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 into common shares of Kutcho at Cdn$0.8125 per share. Once the Kutcho Convertible Note has been outstanding for 24 months, Kutcho has the right to repay the Kutcho Convertible Note early, subject to the applicable pre-payment cash penalties as follows:

• 25% of the outstanding amount if pre-paid on or after 24 months until 36 months;

• 20% of the outstanding amount if pre-paid on or after 36 months until 60 months; and

• 15% of the outstanding amount if pre-paid on or after 60 months until maturity.

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 Company’s long-term investments in common shares (“LTI’s”) are held for long-term strategic purposes and not for trading purposes. 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.

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 Unrealized Fair Value Losses (Gains), Net. 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.

Acquisitions of Long-Term Investments

In connection with the termination of the San Dimas SPA (Note 12), on May 10, 2018, the Company received 20,914,590 First Majestic common shares with a fair value of $151 million¹.

Disposal of Long-Term Investments

As announced by Arizona Mining Inc. and South32 Limited on August 10, 2018, South32 has completed its acquisition of all of the issued and outstanding common shares of Arizona Mining. As a result, subsequent to June 30, 2018, the Company has disposed of its investment in Arizona Mining and will receive cash consideration for its investment in accordance with the terms of the acquisition.

20.2. 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 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 years.

Notes to the Condensed Interim Consolidated Financial Statements

Three and Six Months Ended June 30, 2018 (US Dollars - Unaudited)

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 periods.

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 historic average share price volatility. The weighted average fair value of share purchase options granted and principal assumptions used in applying the Black-Scholes option pricing model are as follows:

During the three months ended June 30, 2017, the weighted average share price at the time of exercise was Cdn$29.08 per share (six months - Cdn$27.87 per share).

20.3. 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 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.

For the same period in 2017, the Company issued 370 RSUs with a fair value of Cdn$27.60 per RSU (six months - 140,780 RSUs with a fair value of $3 million or Cdn$27.51 per RSU).

As of June 30, 2018, there were 403,951 RSUs outstanding. For the comparable period in 2017, there were 311,411 RSUs outstanding.

20.4. Long-Term Investment Revaluation Reserve

The Company’s long-term investments in common shares (Note 17) are held for long-term strategic purposes and not for trading purposes. Upon the application of IFRS 9, Financial Instruments, 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 to offset the loss.

21. Stock Based Compensation

The Company’s stock based compensation consists of share purchase options (Note 20.2), restricted share units (Note 20.3) and performance share units (Note 21.1). 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.

21.1. 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 silver and gold.

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.

During the three months ended June 30, 2018, the Company issued 1,590 PSUs (six months - 220,260 PSUs). For the comparable period of the previous year, the Company issued 730 PSUs (six months - 196,890 PSUs).

1) Subject to an annual inflationary adjustment with the exception of Loma de La Plata and Sudbury.

2) All amounts are measured on a per ounce basis with the exception of cobalt which is measured on a per pound basis. Should the prevailing market price for the applicable metal be lower than this amount, the per ounce or per pound 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 $4.35 per ounce, subject to an annual inflationary factor.

3) Under the terms of the San Dimas precious metal purchase agreement, 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.

4) The Company is committed to pay Glencore 20% of the spot price of silver for each ounce of silver delivered under the Antamina silver purchase agreement.

5) Gold recoveries will be set at 55% for the Constancia deposit and 70% for the Pampacancha deposit until 265,000 ounces of gold have been delivered to the Company.

6) Subject to an increase to $9.90 per ounce of silver and $550 per ounce of gold after the initial 40-year term.

7) 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 life of mine.

8) The Company is committed to pay Sabanye 18% of the spot price of gold and palladium for each ounce of gold and palladium delivered under the Stillwater precious metal purchase agreement until such time as the upfront cash payment is reduced to $NIL and 22% of the spot price thereafter.

9) Once the Company has received 31 million pounds of cobalt, the Company’s attributable cobalt production to be purchased will be reduced to 21.2%.

10) The Company is committed to pay Vale 18% of the spot price of cobalt per pound of cobalt delivered under the agreement until such time as the upfront cash payment is reduced to $NIL, and 22% of the spot price thereafter.

11) Wheaton is committed to purchase from Glencore a per annum amount equal to the first 1.5 million ounces of payable silver produced at Yauliyacu and 50% of any excess.

12) Should the market price of silver exceed $20 per ounce, in addition to the $8.85 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 $18.85 per ounce of silver delivered.

13) In October 2015, in order to incentivize additional exploration and potentially extend the limited remaining mine life of Stratoni, Wheaton and Eldorado Gold agreed to modify the Stratoni silver purchase agreement. The primary modification is to increase the production price per ounce of silver delivered to Wheaton over the current fixed price by one of the following amounts: (i) $2.50 per ounce of silver delivered if 10,000 meters of drilling is completed outside of the existing ore body and within Wheaton’s defined area of interest (“Expansion Drilling”); (ii) $5.00 per ounce of silver delivered if 20,000 meters of Expansion Drilling is completed; and (iii) $7.00 per ounce of silver delivered if 30,000 meters of Expansion Drilling is completed. Drilling in all three cases must be completed by December 31, 2020, in order for the agreed upon increase in production price to be initiated. The figures in the above table reflect the fact that Eldorado completed 10,000 meters of Expansion Drilling in July 2018.

14) The Company is committed to acquire 100% of the first 30,000 ounces of gold produced per annum and 50% thereafter.

15) The production payment per ounce of gold delivered to Wheaton is to be increased over the current fixed price in periods where the market price of copper is lower than $2.50 per pound.

16) Wheaton only has the rights to silver contained in concentrate containing less than 15% copper at the Aljustrel mine.

17) During the second quarter of 2018, the Company agreed to amend the precious metal purchase agreement with Almina to increase the production payments to 50% of the amount received under the respective concentrate sales contracts and to fix silver payable rates for a period of two years and limit rate decreases thereafter.

18) The production payment related to the Keno Hill silver interest is a function of the silver head grade and silver spot price in the month in which the silver is produced.

19) Terms of the agreement not yet finalized.

20) Once 90 million silver equivalent ounces attributable to Wheaton have been produced, the attributable production to be purchased will decrease to 66.67% of silver production and 16.67% of gold production for the life of mine.

21) 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 silver and gold production for the life of mine.

22) The Company is committed to pay Kutcho 20% of the spot price of silver and gold for each ounce of silver and gold delivered under the Kutcho Early Deposit Agreement.

Salobo

The Salobo mine currently has a mill throughput capacity of 24 million tonnes per annum (“Mtpa”). If actual throughput is expanded above 28 Mtpa within a predetermined period, and depending on the grade of material processed, Wheaton will be required to make an additional payment to Vale based on a set fee schedule ranging from $113 million if throughput is expanded beyond 28 Mtpa by January 1, 2036, up to $953 million if throughput is expanded beyond 40 Mtpa by January 1, 2021.

Stillwater

On July 25, 2018, in connection with the Stillwater precious metal purchase agreement (Note 27), the Company paid to Sibanye a total upfront cash payment of $500 million.

Taxes

2013 Taxation Year: Domestic

On July 24, 2018, the Company received a Notice of Reassessment for the 2013 taxation year (“the 2013 Domestic Reassessment”) 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 in respect of 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 basis over the estimated recoverable reserves, and where applicable, resources and exploration potential at the respective mine. The Company’s position, as reflected in its filed Canadian income tax returns, is 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, as provided for in the PMPAs.

Management believes the Company’s position is the correct one, and that it has filed its tax returns and paid applicable taxes in compliance with Canadian tax law. Wheaton intends to file a notice of objection within the 90-day period required under the Income Tax Act (Canada) (the “Act”) challenging the 2013 Domestic Reassessment. Even if the Company is unsuccessful in defending its position, it would not result in any additional tax for the 2013 taxation year after applying non-capital losses carried back from subsequent taxation years. However, interest and penalties of approximately $0.7 million (Cdn$0.9 million) remain owing (calculated to the date of the 2013 Domestic Reassessment), 50% of which must be paid in order to object to the 2013 Domestic Reassessment.

The CRA is conducting a domestic audit for the 2014 and 2015 taxation years. The 2016 and 2017 taxation years remain open to a domestic audit. If CRA were to reassess the Company’s Canadian PMPAs for the 2014-2017 taxation years on the same basis as CRA has reassessed the Company in the 2013 Domestic Reassessment, the Company estimates that it would not result in a material amount of additional tax, interest, and penalties.

On September 24, 2015, the Company received Notices of Reassessment (the “Reassessments”) from the CRA totaling $268 million (Cdn$353 million) for federal and provincial tax, transfer pricing penalties, interest and other penalties for the 2005-2010 taxation years. The CRA’s position in the Reassessments is that the transfer pricing provisions of the Act relating to income earned by the Company’s foreign subsidiaries outside of Canada should apply such that the income of Wheaton subject to tax in Canada should be increased by an amount equal to substantially all of the income earned outside of Canada by the Company’s foreign subsidiaries for the 2005-2010 taxation years. Management believes that the Company has filed its tax returns and paid applicable taxes in compliance with Canadian tax law, and as a result no amounts have been recorded for any potential liability arising from this matter. Wheaton is vigorously defending its tax filing positions.

On January 8, 2016, the Company commenced an appeal in the Tax Court of Canada. The Company was required to make a deposit of 50% of the reassessed amounts of tax, interest and penalties. Instead of making this deposit in cash, on March 15, 2016, the Company posted security in the form of a letter of guarantee in the amount of $146 million (Cdn$192 million), which included interest accrued to March 2016 plus estimated interest for the following year.

Three and Six Months Ended June 30, 2018 (US Dollars - Unaudited)

In March 2017 and 2018, additional letters of guarantee in the amounts of $8 million (Cdn$11 million) and $8 million (Cdn$10 million), respectively, were delivered to the CRA as security for additional estimated interest for the respective following year. The Company is currently in the discovery phase of the appeal, with a trial scheduled to commence mid-September 2019 for a two month period.

2011 – 2015 Taxation Years: Audit of International Transactions

The CRA has also commenced an audit of the Company’s international transactions covering the 2011-2015 taxation years, which is currently ongoing. The Company has not received any proposal or notices of reassessment for the 2011-2015 taxation years in connection with this audit.

For ease of reference, the following provides an overview of the current status of CRA matters relating to income earned by the Company’s foreign subsidiaries outside of Canada:

Taxation Years	CRA Position/Status	Potential Income Inclusion	Potential Income Tax Payable (1)	Payments Made	Timing
2005-2010	Transfer pricing provisions of the Act should apply such that Wheaton’s income subject to tax in Canada should be increased by an amount equal to substantially all of the income earned outside of Canada by Wheaton’s foreign subsidiaries.	CRA has reassessed Wheaton and is seeking to increase Wheaton’s income subject to tax in Canada by Cdn$715 million.	CRA has reassessed Wheaton and is seeking to impose income tax of $153 million (Cdn$201 million).(2),(3)	Wheaton has posted security in the form of letters of guarantee totaling $162 million (Cdn$213 million) reflecting 50% of all assessed tax, penalties and interest accrued to March 15, 2019.(3),(4)	An appeal in the Tax Court of Canada commenced January 8, 2016. Trial scheduled to commence mid-September 2019 for a two month period.
2011-2015	CRA commenced an audit of 2011-2015 taxation years. CRA has not issued a proposal or reassessment.	If CRA were to reassess on a similar basis as 2005-2010 taxation years, the Company estimates CRA would seek to increase Wheaton’s income subject to tax in Canada by approximately $1.9 billion.(5), (8)	If CRA were to reassess on a similar basis as 2005-2010 taxation years, the Company estimates CRA would seek to impose income tax of approximately $384 million (Cdn$505 million).(5), (6), (8)	N/A	Time to complete CRA audit unknown.
2016-2017	Remains open to audit by CRA.	If CRA were to audit and then reassess on a similar basis as 2005-2010 taxation years, the Company estimates CRA would seek to increase Wheaton’s income subject to tax in Canada by approximately $580 million.(5), (8)	If CRA were to reassess on a similar basis as 2005-2010 taxation years, the Company estimates CRA would seek to impose income tax of approximately $149 million (Cdn$197 million).(5),(7),(8)	N/A	N/A

1) For the taxation years ended after December 31, 2010, the Company files its Canadian tax returns in US dollars. However, taxes payable, if any, are payable in Canadian dollars based on the exchange rate applicable on the original payment due date. As a result, the US dollar amounts reflected in the table above are subject to fluctuations in the value of the Canadian dollar relative to the US dollar. Canadian dollar amounts in this table have been converted to US dollars at the exchange rate applicable at the balance sheet date as quoted by the Bank of Canada.

2) For the 2005-2010 taxation years, transfer pricing penalties of $54 million (Cdn$72 million) and interest and other penalties of $61 million (Cdn$81 million) were also assessed by the CRA. The total reassessment issued on September 24, 2015 was $268 million (Cdn$353 million). Additional interest accruing to December 31, 2017 on the total amount reassessed is estimated at $34 million (Cdn$45 million) for the 2005-2010 taxation years.

3) As a consequence of the CRA’s reassessment of the 2005-2010 taxation years and the 2013 Domestic Reassessment, CRA reassessed the 2011 and 2012 taxation years to amend the non-capital losses available to offset the taxable income of $12 million and $14 million, respectively. As a result of the 2013 Domestic Reassessment, additional tax, interest, and penalties of about $1.6 million (Cdn$2.2 million) was owing for the 2011 and 2012 taxation years. The Company will be filing Notices of Objection with respect to these reassessments and accordingly, the Company will be required to pay 50% of the additional amounts owing. These reassessments do not relate to the CRA international audit of the 2011-2015 taxation years.

4) Estimates of interest given as of the date stated. Interest accrues until payment date.

5) The estimates of income inclusion and tax payable are computed on the basis that the cost of precious metal acquired under the PMPAs is equal to the cash cost plus an amortized amount of the up-front payment and without taking into account any available Canadian non-capital losses.

6) If CRA were to reassess the 2011-2015 taxation years and continue to apply transfer pricing penalties, management estimates that transfer pricing penalties of approximately $187 million and interest (calculated to December 31, 2017) and other penalties of approximately $110 million (Cdn$145 million) may be applicable for the 2011-2015 taxation years.

7) If CRA were to reassess the 2016-2017 taxation years and continue to apply transfer pricing penalties, management estimates that transfer pricing penalties of approximately $58 million and interest (calculated to December 31, 2017) and other penalties of approximately $9 million (Cdn$12 million) may be applicable for the 2016-2017 taxation years.

8) If the cost of precious metal acquired under the PMPAs is equal to the market value of precious metal while the deposit is outstanding (where applicable to an agreement), and the cash cost thereafter, the estimated amounts for the 2011 – 2015 taxation years would be as follows: (i) income inclusion of $1.6 billion; (ii) tax payable of $331 million (Cdn$435 million); (iii) transfer pricing penalties (if applied) of $161 million; and (iv) interest and other penalties of $93 million (Cdn$123 million). On this basis, the estimated amounts for the 2016 – 2017 taxation years would be as follows: (i) income inclusion of $260 million; (ii) tax payable of $68 million (Cdn$89 million); (iii) transfer pricing penalties (if applied) of $26 million; and (iv) interest and other penalties of $4 million (Cdn$6 million).

U.S. Shareholder Class Action

During July 2015, after the Company disclosed that the CRA was proposing that they would issue the Reassessments, two putative securities class action lawsuits were filed against the Company in the U.S. District Court for the Central District of California in connection with the Proposal (the “Complaints”).

On October 19, 2015, the Complaints were consolidated into one action, In re Silver Wheaton Securities Litigation, as against the Company, Randy Smallwood, President & Chief Executive Officer, Gary Brown, Senior Vice President & Chief Financial Officer and Peter Barnes, former Chief Executive Officer (together the “Defendants”) and a lead plaintiff (the “Plaintiff”) was selected. The Plaintiff filed a consolidated amended complaint in December 2015, and then filed a second amended complaint in April 2018 (the “Amended Complaint”). The Amended Complaint alleges, among other things, that the Defendants made false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, prospects and performance in violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Specifically, the Amended Complaint focuses on the Reassessments. The Amended Complaint purports to be brought on behalf of persons who purchased or otherwise acquired the Company’s securities in the United States during an alleged class period of March 30, 2011 to July 6, 2015.

At a hearing on June 6, 2016, the Court denied the Defendants’ motion to dismiss. A denial of such a motion is not a ruling on the merits of the claims in the lawsuit. Certification of the class was granted by the Court on May 11, 2017. Defendants have filed motions to dismiss the second amended complaint and a hearing is set for November 2018. No trial date is currently set for this matter.

The Company believes the allegations are without merit and intends to vigorously defend against this matter. No amounts have been recorded for any potential liability arising from this matter, as the original Complaints do not specify a quantum of damages and the Company cannot reasonably predict the outcome.

Canadian Shareholder Class Action

By Notice of Action dated August 10, 2016 (as amended September 2, 2016), 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 statement of claim filed alleges, among other things, misrepresentation pursuant to primary and secondary market civil liability provisions under the Securities Act (Ontario), common law negligence and negligent misrepresentation. The claim focuses on the Reassessments. The statement of claim purports to be brought on behalf of persons who (i) acquired Wheaton common shares in Wheaton’s March 2015 public offering, and (ii) acquired Wheaton common shares in the secondary market, other than in the United States, during an alleged class period of August 14, 2013 to July 6, 2015 inclusive.

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.

Other

Due to the size, complexity and nature of the Company’s operations, various legal and tax matters are outstanding from time to time. 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.

Declaration of Dividend

On August 14, 2018, the Board of Directors declared a dividend in the amount of $0.09 per common share as per the Company’s stated dividend policy whereby the quarterly dividend will be equal to 30% of the average of the operating cash flow of the previous four quarters. This dividend is payable to shareholders of record on August 29, 2018 and is expected to be distributed on or about September 13, 2018. 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 3% of the Average Market Price, as defined in the DRIP.

Acquisition of Stillwater Mineral Stream Interest

On July 16, 2018, the Company announced that it had entered into an agreement with Sibanye to acquire an amount of gold and palladium equal to a fixed percentage of production from the Stillwater and East Boulder mines located in Montana in the United States (collectively referred to as the “Stillwater” mines) for a total upfront cash payment of $500 million. Deliveries under the agreement will begin July 1, 2018 at a fixed payable rate of 99% for gold and 99.6% for palladium.

Under the terms of the agreement, the Company has acquired an amount of gold equal to 100% of the gold production for the life of the mine and an amount of palladium equal to 4.5% of the palladium production until 375,000 ounces of palladium have been delivered to Wheaton, after which the Company’s entitlement will be reduced to 2.25% of the palladium production until 550,000 ounces of palladium have been delivered to Wheaton, after which the Company’s entitlement will be reduced to 1.00% of the palladium production for the life of mine.

In addition to the initial upfront cash consideration, the Company will make ongoing payments of 18% of the spot price of gold and palladium for each ounce of gold and palladium delivered under the agreement until the net market value of gold and palladium delivered to Wheaton exceeds the initial upfront cash deposit, and 22% of the spot price thereafter¹.

Acquisition of Adventus Zinc Corporation Shares

On July 17, 2018, the Company acquired 7,093,392 common shares of Adventus Zinc Corporation (“Adventus”) in a private placement transaction, for total consideration of Cdn$6 million, representing 9.99% of Adventus’ issued and outstanding common shares.

¹  The production payment is subject to further downward adjustment based upon Sibanye’s leverage ratios.

Description of Business and Nature of Operations

1. Description of Business and Nature of Operations

Wheaton Precious Metals Corp. is a mining company which generates its revenue primarily from the sale of precious metals. 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”) and the New York Stock Exchange (“NYSE”) under the symbol WPM.

Including the agreements entered into after June 30, 2018 (Note 27), the Company has entered into 23 long-term purchase agreements (three of which are early deposit agreements), with 16 different mining companies, for the purchase of precious metals and cobalt (“precious metal purchase agreements” or “PMPA”) relating to 19 mining assets which are currently operating and 9 which are at various stages of development, located in 11 countries. Pursuant to the precious metal purchase agreements, Wheaton acquires metal production from the counterparties for an initial upfront payment plus an additional cash payment for each ounce 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, 2018 were authorized for issue as of August 14, 2018 in accordance with a resolution of the Board of Directors.

2. Basis of Presentation

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”). 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, 2017 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, 2017.

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, 2018 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. New Accounting Standards Effective in 2018

IFRS 9 – Financial Instruments (amended 2014):

On January 1, 2018, the Company adopted IFRS 9 (2014) – Financial Instruments (amended 2014) (“IFRS 9 (2014)”). The Company had previously adopted IFRS 9 (2009) – Financial Instruments effective January 1, 2010. The adoption of IFRS 9 (2014) did not materially impact the accounting policies and methods of application relative to the Company’s financial instruments.

IFRS 15 – Revenue from Contracts with Customers:

On January 1, 2018, the Company adopted IFRS 15 – Revenue from Contracts with Customers (“IFRS 15”) which supersedes IAS 18 – Revenue (“IAS 18”). IFRS 15 establishes a single five-step model framework for determining the nature, amount, timing and uncertainty of revenue and cash flows arising from a contract with a customer. The standard is effective for annual periods beginning on or after January 1, 2018. IFRS 15 requires entities to recognize revenue when ‘control’ of goods or services transfers to the customer whereas the previous standard, IAS 18, required entities to recognize revenue when the ‘risks and rewards’ of the goods or services transfer to the customer. The Company concluded that there is no change in the timing of revenue recognition of its silver and gold credit sales and its silver and gold concentrate sales under IFRS 15 compared to the previous standard as the point of transfer of risks and rewards of the silver and gold and the transfer of control of the silver and gold occur at the same time. As such, no adjustment was required to the Company’s consolidated financial statements as at January 1, 2017 or for the year ended December 31, 2017. Additionally, IFRS 15 requires that variable consideration should only be recognized to the extent that it is highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur. The Company concluded that the adjustments relating to the final assay results for the quantity of concentrate sold under the terms of the concentrate sales contracts are not significant and do not constrain the recognition of revenue.

3.2. Future Changes in Accounting Policies

The IASB has issued the following new or amended standards:

Standards required to be applied for periods beginning on or after January 1, 2019:

• IFRS 16 – Leases: In January 2016, the IASB and the FASB completed its joint project to address concerns by users of financial statements in respect of reduced comparability between financial statements due to the different accounting treatment applied to operating leases as compared to finance leases by removing the distinction between operating leases and finance leases and rather having all leases accounted for as a finance lease, subject to limited exceptions for short-term leases and leases of low value assets. The Company is currently evaluating the impact of this standard and anticipates that upon adoption of this standard, its leases will be capitalized under the classification Right-of-Use Assets, with a corresponding liability for Leases Payable. The total amount to be capitalized is estimated to be $3 million. The Company also expects a reduction in operating cash outflows of approximately $1 million per annum upon the adoption of IFRS 16, with a corresponding increase in financing cash outflows. Lastly, the Company does not anticipate the adoption of this standard will have a material impact on its Consolidated Statement of Earnings.

• IFRIC 23 – Uncertainty over Income Tax Treatments: In June 2017, the IASB issued IFRIC 23 which is effective for periods beginning on or after January 1, 2019. IFRIC 23 provides guidance on the accounting for current and deferred tax liabilities and assets in circumstances in which there is uncertainty over income tax treatments. The extent of the impact of the adoption of IFRIC 23 has not yet been determined.

Early adoption of the above standards is permitted.

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 $5.8 billion at June 30, 2018. 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 precious metal purchase agreements. 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 precious metal purchase agreements. 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 judgement 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 basis over the estimated recoverable proven and probable reserves at the mine corresponding to the specific agreement. The value associated with resources and exploration potential is the value beyond proven and probable reserves at acquisition and is classified as non-depletable until such time as it is transferred to the depletable category as a result of the conversion of resources and/or exploration potential into reserves. To make this allocation, the Company estimates the recoverable reserves, resources and exploration potential at each mining operation. These calculations require the use of estimates and assumptions, including the amount of contained metals, recovery rates and payable rates. Changes to these assumptions may impact the estimated recoverable reserves, resources or exploration potential which could directly impact the depletion rates used. Changes to depletion rates are accounted for prospectively.

4.3. Impairment of Assets

The Company assesses each precious metal purchase agreement 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 precious metal purchase agreement 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 silver and gold has been extremely volatile over the past several years and should price levels decline in the future for an extended period of time, the Company may need to re-evaluate the long-term metal price assumptions used for impairment testing. A significant decrease in long-term metal price assumptions may be an indication of potential impairment. Should the Company conclude that it has an indication of impairment at any balance sheet date, the Company is required to perform an impairment assessment.

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 20.2, 20.3, and 21.1, respectively.

4.5. Valuation of Convertible Note Receivable

As more fully described in Note 16, the Company measures its convertible note receivable with Kutcho Copper Corp. at fair value for financial reporting purposes. This calculation requires the use of estimates and assumptions such as rate of interest prevailing at the balance sheet date for instruments of similar term and risk, expected dividend yield, expected volatility and expected remaining life of the convertible note receivable.

4.6. Valuation of Minto Derivative Liability

As more fully described in Note 5.3, the Company’s Minto precious metal purchase agreement has a pricing mechanism whereby there is an increase to the production payment per ounce of gold delivered to Wheaton over the current fixed price in periods where the market price of copper is lower than $2.50 per pound. As this pricing mechanism meets the definition of a derivative, it is reflected at fair value for financial reporting purposes. This calculation requires the use of estimates and assumptions such as long-term price of copper, recoverable ounces of gold and operating performance.

4.7. 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

4.8. 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.

4.9. Significant Influence over Kutcho

Note 15 describes Kutcho Copper Corp. (“Kutcho”) as an associate though the Company only owns a 13% ownership interest in Kutcho. The Company has determined it has significant influence over Kutcho by virtue of the convertible instruments of Kutcho that the Company owns.

4.10. 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 shipments of metals 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 and 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 estimates and assumptions are consistent with those used in testing asset impairment of precious metal purchase agreements. The amount of deferred income tax assets recognized on the balance sheet could be reduced if the actual results differ significantly from forecast. The Company reassesses its deferred income tax assets at the end of each reporting period.

Fair Value Measurements

5. Fair Value Measurements

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.

Other accounts receivables and accounts payables and accrued liabilities are non-interest bearing and are stated at carrying values, which approximate fair values due to the short terms to maturity. Where necessary, other receivables are reported net of allowances for uncollectable amounts.

The Company’s bank debt (Note 18.1) is reported at amortized cost using the effective interest method. The carrying value of the bank debt approximates its fair value.

5.1. 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.

5.2. 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 silver and gold 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.

5.3. Valuation Techniques for Level 3 Assets

Convertible Note Receivable

The fair value of the Kutcho Convertible Note receivable (Note 16), 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 Kutcho Convertible Note receivable.

As the expected volatility and market interest rate are not observable inputs, the Kutcho 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 Unrealized Fair Value Losses (Gains), Net (Note 10).

Management estimates that the market interest rate on similar borrowings without the conversion feature was approximately 15% and has used an implied volatility of 30% in valuing the convertibility feature. If (i) the market interest rate used had been 2% lower or higher at the respective balance sheet date; or (ii) the implied volatility used had been 10% higher or lower at the respective balance sheet date, then the value of the Kutcho Convertible Note receivable would have increased or decreased by approximately $1 million.

Minto Derivative Liability

In October 2017, in order to incentivize Capstone Mining Corp. to extend the Minto mine life, the Company agreed to amend the Minto precious metal purchase agreement. The primary modification is to increase the production payment per ounce of gold delivered to Wheaton over the current fixed price in periods where the market price of copper is lower than $2.50 per pound. As this pricing mechanism meets the definition of a derivative, it is reflected at fair value for financial reporting purposes. At June 30, 2018 and December 31, 2017, the Company estimated the fair value of this derivative liability to be $NIL as the long-term outlook for copper based on a consensus derived from a number of sources including analysts and other market observers exceeds $2.50 per pound over the duration of the anticipated remaining mine life.

Silver and Gold Credit Sales

Under certain precious metal purchase agreements, silver and/or gold is acquired from the mine operator in the form of silver or gold credits, which is then sold through a network of third party brokers or dealers. Revenue from silver and gold credit sales is recognized at the time of the sale of such credits, which is also the date that control of the silver or gold is transferred to the customer.

The Company will occasionally enter into forward contracts in relation to silver or gold deliveries that it is highly confident will occur within a given quarter. No forward contracts were outstanding at June 30, 2018 or December 31, 2017. 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 silver or gold.

Concentrate Sales

Under certain precious metal purchase agreements, silver and/or gold 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 silver or gold in concentrate form, final silver or gold 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 silver or gold. The contracts, in general, provide for a provisional payment based upon provisional assays and quoted silver and gold prices. Final settlement is based upon the average applicable price for the Quotational Period applied to the actual number of silver or gold 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 buyer, which is also the date that control of the silver or gold 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.

Proceeds relative to the Mercator Minerals bankruptcy

During the three months ended March 31, 2017, the Company received an additional $1 million settlement related to the bankruptcy of Mercator Minerals Ltd. (“Mercator”) with whom Wheaton had a silver purchase agreement relative to Mercator’s Mineral Park mine in the United States (the “Mercator Bankruptcy”). This silver interest was fully written off during the year ended December 31, 2014 and as such further proceeds, if any, will be recognized as a component of net earnings.

Guarantee fees - Primero Revolving Credit Facility

On March 30, 2017, Wheaton provided a guarantee to the lenders under Primero Mining Corp.’s (“Primero”) previously outstanding revolving credit facility for which Primero paid a fee of 5% per annum (the “Guarantee”). The Guarantee was cancelled on May 10, 2018, being the date First Majestic Silver Corp. (“First Majestic”) completed the previously disclosed acquisition of all the issued and outstanding common shares of Primero.

2) On March 29, 2017, the Company amended its silver purchase agreement with Alexco Resource Corp. (“Alexco”) to adjust the silver production payment so that it will be a percentage of the spot silver price that increases with lower mill silver head grades and lower silver prices, and decreases with higher mill silver head grades and higher silver prices, subject to certain ceiling and floor grades and prices. In addition, the outside completion date was extended to December 31, 2019 and the area of interest was expanded to include properties currently owned by Alexco and properties acquired by Alexco in the future which fall within a one kilometer radius of existing Alexco holdings in the Keno Hill Silver District. As consideration, on April 10, 2017, Alexco issued 3 million shares to Wheaton which had a fair value of $5 million. The fair value of these shares have been reflected as a reduction to the cost base of the Keno Hill silver interest.

3) Comprised of the Los Filos, Zinkgruvan, Yauliyacu, Stratoni, Keno Hill, Cozamin, Neves-Corvo, Minto, Aljustrel, Loma de La Plata, Pascua-Lama, Lagunas Norte, Pierina, Veladero, Rosemont and 777 silver interests. The Cozamin precious metal purchase agreement expired on April 4, 2017 and the fully depleted value of this contract has been reflected as a disposal.

4) Comprised of the Coleman, Copper Cliff, Garson, Stobie, Creighton, Totten and Victor gold interests.

5) Comprised of the Minto, Rosemont and 777 gold interests.

The value allocated to reserves is classified as depletable upon a mining operation achieving first production and is depleted on a unit-of-production basis over the estimated recoverable proven and probable reserves at the mine. The value associated with resources and exploration potential is allocated at acquisition and is classified as non-depletable until such time as it is transferred to the depletable category, generally as a result of the conversion of resources or exploration potential into reserves.

Termination of the San Dimas Silver Interest and Acquisition of the San Dimas Gold Interest

On October 15, 2004, the Company entered into an agreement with Goldcorp Inc. (“Goldcorp”) to acquire an amount equal to 100% of the silver produced by Goldcorp’s Luismin mining operations in Mexico, including the San Dimas mine. On August 6, 2010, Goldcorp completed the sale of San Dimas to Primero Mining Corp. (“Primero”), and pursuant to the amended silver purchase agreement with Primero (the “San Dimas SPA”), the Company acquired 100% of the payable silver produced at San Dimas up to 6 million ounces annually, and 50% of any excess for the life of the mine. Goldcorp also provided a guarantee with respect to the delivery by Primero of all silver produced and owing to the Company until 2029 (the “Goldcorp Guarantee”).

On May 10, 2018, First Majestic completed the previously disclosed acquisition of all the issued and outstanding common shares of Primero (the “Acquisition”). In connection with the Acquisition, on May 10, 2018, the Company terminated the San Dimas SPA and entered into a new precious metal purchase agreement with First Majestic relating to the San Dimas mine (the “San Dimas PMPA”). As consideration for terminating the San Dimas SPA, the Company received a cash payment of $220 million and 20,914,590 First Majestic common shares with a fair value of $151 million (the “First Majestic Shares¹”), and the Goldcorp Guarantee was terminated in exchange for a payment of $10 million, with the net result being that the Company has reflected a gain on disposal of the San Dimas SPA in the amount of $246 million, calculated as follows:

¹  The First Majestic Shares represent approximately 11% of First Majestic’s current issued and outstanding shares and are subject to resale restrictions, including a six month hold period (subject to certain exceptions) with volume selling restrictions thereafter.

Gain on disposal of the San Dimas SPA	$	245,715

Under the terms of the new San Dimas PMPA, for which the Company paid total upfront cash consideration of $220 million, 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 70:1.¹ In addition to the $220 million upfront cash payment, the Company will make ongoing payments of $600 per gold ounce delivered.

Acquisition of the Voisey’s Bay Cobalt Interest

On June 11, 2018, the Company entered into an agreement to acquire from Vale S.A. (“Vale”) an amount of cobalt equal to 42.4% of the cobalt production from its Voisey’s Bay mine, located in Canada, until the delivery of 31 million pounds of cobalt and 21.2% of cobalt production thereafter for the life of mine for a total upfront cash payment of $390 million. In addition, Wheaton will make ongoing payments of 18% of the spot price of cobalt per pound of cobalt delivered under the agreement until such time as the upfront cash payment is reduced to $NIL and 22% of the spot price of cobalt thereafter. Payable rates for cobalt in concentrate have generally been fixed at 93.3%. Deliveries under the contract are scheduled to begin effective January 1, 2021.

Early Deposit Mineral Stream Interests

13. 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:

	Mine Owner										Attributable Production to be Purchased
Early Deposit Mineral Stream Interests			Location of Mine		Upfront Consideration Paid to Date 1		Upfront Consideration to be Paid 1, 2		Total Upfront Consideration¹		Silver			Gold			Term of Agreement

1) Expressed in United States dollars, rounded to the nearest thousand; excludes closing costs.

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 to be purchased will decrease to 66.67% of silver production and 16.67% of gold 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 silver and gold production for the life of mine.

¹  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.

Mineral Royalty Interest

14. Mineral Royalty Interest

On August 7, 2014, the Company purchased a 1.5% net smelter return royalty interest (the “Royalty”) in the Metates properties located in Mexico from Chesapeake Gold Corp. (“Chesapeake”) for the life of mine. Under the terms of the agreement, the Company paid total upfront cash consideration of $9 million and at any time prior to August 7, 2019, Chesapeake may reacquire two-thirds ( ²⁄₃) of the Royalty, or 1%, for the sum of $9 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 this royalty agreement.

Investment in Associate

15. Investment in Associate

Kutcho

Effective December 14, 2017, in connection with the Kutcho Early Deposit Agreement (Note 13), the Company participated in an equity financing undertaken by Kutcho Copper Corp. (“Kutcho”) acquiring, by way of private placement, 6,153,846 common shares and warrants to acquire an additional 3,076,923 common shares of Kutcho for total consideration of $3 million (Cdn$4 million). Additionally, the Company advanced to Kutcho $16 million (Cdn$20 million) in exchange for a subordinated secured convertible term debt loan agreement receivable bearing interest at 10% per annum (the “Kutcho Convertible Note”) (see Note 16).

As at January 31, 2018, Kutcho had 47,770,378 shares issued and outstanding, resulting in Wheaton owning approximately 13% of Kutcho on a non-diluted basis. However, as the convertible instruments described above are currently exercisable, on a fully diluted basis, Wheaton has the potential to own approximately 36% of Kutcho (45% on a non-fully diluted basis). As a result of the potential ownership position, the Company has concluded that it has significant influence over Kutcho and as such the investment in Kutcho is considered an Investment in Associate which is accounted for using the equity method. The Company records its share of Kutcho’s profit or loss based on Wheaton’s ownership interest in Kutcho on a non-diluted basis. As Kutcho’s fiscal year end is April 30, Wheaton has reported its share of Kutcho’s loss relative to Kutcho’s third quarter ended January 31, 2018, which represents the last period publicly reported by Kutcho as at the date these financial statements were authorized for issue.

A summary of the carrying value of the Kutcho Investment in Associate and the losses recognized as a component of the Company’s net earnings during 2018 is presented below:

16. Convertible Note Receivable

Kutcho

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 has the option to defer the first three interest payments until December 31, 2019, at which point one half of the deferred interest is payable in cash and the other half of the deferred interest can, at Kutcho’s option, either (i) be paid in cash; or (ii) be deferred for an additional period not to exceed 4 years. In the event Kutcho elects to make the second deferral, Wheaton can, at its option, convert the remaining deferred interest into common shares of Kutcho.

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 into common shares of Kutcho at Cdn$0.8125 per share. Once the Kutcho Convertible Note has been outstanding for 24 months, Kutcho has the right to repay the Kutcho Convertible Note early, subject to the applicable pre-payment cash penalties as follows:

• 25% of the outstanding amount if pre-paid on or after 24 months until 36 months;

• 20% of the outstanding amount if pre-paid on or after 36 months until 60 months; and

• 15% of the outstanding amount if pre-paid on or after 60 months until maturity.

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 Company’s long-term investments in common shares (“LTI’s”) are held for long-term strategic purposes and not for trading purposes. 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.

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 Unrealized Fair Value Losses (Gains), Net. 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.

Acquisitions of Long-Term Investments

In connection with the termination of the San Dimas SPA (Note 12), on May 10, 2018, the Company received 20,914,590 First Majestic common shares with a fair value of $151 million¹.

Disposal of Long-Term Investments

As announced by Arizona Mining Inc. and South32 Limited on August 10, 2018, South32 has completed its acquisition of all of the issued and outstanding common shares of Arizona Mining. As a result, subsequent to June 30, 2018, the Company has disposed of its investment in Arizona Mining and will receive cash consideration for its investment in accordance with the terms of the acquisition.

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, 2018.

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 1.20% to 2.20%; or (ii) the Bank of Nova Scotia’s Base Rate plus 0.20% to 1.20%. Undrawn amounts under the Revolving Facility are subject to a stand-by fee of 0.24% to 0.44% per annum, dependent on the Company’s leverage ratio.

¹  The First Majestic Shares represent approximately 11% of First Majestic’s current issued and outstanding shares and are subject to resale restrictions, including a six month hold period (subject to certain exceptions) with volume selling restrictions thereafter.

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.

18.2. Letters of Guarantee

Warrants outstanding		10,000,000	$	43.75		1.00	$	83,077

The warrants, which expire on February 28, 2023, were valued using a Black-Scholes option pricing model. Each warrant entitles the holder the right to purchase one of the Company’s common shares.

20.2. 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 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 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 periods.

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 historic average share price volatility. The weighted average fair value of share purchase options granted and principal assumptions used in applying the Black-Scholes option pricing model are as follows:

20.3. 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 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 reserve from January 1, 2017 to June 30, 2018 is presented below:

(in thousands)	Restricted Share Units Reserve

During the three months ended June 30, 2018, the Company issued 790 RSUs with a fair value of Cdn$27.96 per RSU (six months - 161,060 RSUs with a fair value of $3 million or Cdn$26.25 per RSU). For the same period in 2017, the Company issued 370 RSUs with a fair value of Cdn$27.60 per RSU (six months - 140,780 RSUs with a fair value of $3 million or Cdn$27.51 per RSU).

As of June 30, 2018, there were 403,951 RSUs outstanding. For the comparable period in 2017, there were 311,411 RSUs outstanding.

20.4. Long-Term Investment Revaluation Reserve

The Company’s long-term investments in common shares (Note 17) are held for long-term strategic purposes and not for trading purposes. Upon the application of IFRS 9, Financial Instruments, 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 to offset the loss.

A continuity schedule of the Company’s long-term investment revaluation reserve from January 1, 2017 to June 30, 2018 is presented below:

Stock Based Compensation

21. Stock Based Compensation

The Company’s stock based compensation consists of share purchase options (Note 20.2), restricted share units (Note 20.3) and performance share units (Note 21.1). 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.

21.1. 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 silver and gold.

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.

During the three months ended June 30, 2018, the Company issued 1,590 PSUs (six months - 220,260 PSUs). For the comparable period of the previous year, the Company issued 730 PSUs (six months - 196,890 PSUs).

A continuity schedule of the Company’s outstanding PSUs (assuming a performance factor of 100% is achieved over the performance period) from January 1, 2017 to June 30, 2018 is presented below:

	Number of PSUs Outstanding
At January 1, 2017		717,564

Earnings per Share ("EPS") and Diluted Earnings per Share ("Diluted EPS")

22. Earnings per Share (“EPS”) and Diluted Earnings per Share (“Diluted EPS”)

Diluted earnings per share is calculated using the treasury method which assumes that outstanding share purchase options and warrants, with exercise prices that are lower than the average market price of the Company’s common shares for the relevant period, are exercised and the proceeds are used to purchase shares of the Company at the average market price of the common shares for the relevant period.

Diluted EPS is calculated based on the following weighted average number of shares outstanding:

	Three Months Ended June 30				Six Months Ended June 30
(in thousands)	2018		2017		2018		2017
Basic weighted average number of shares outstanding		443,191		441,784		442,961		441,635
Effect of dilutive securities
Share purchase options		175		275		131		277
Restricted share units		404		311		361		256
Diluted weighted average number of shares outstanding		443,770		442,370		443,453		442,168

The following table lists the number of share purchase options and share purchase warrants excluded from the computation of diluted earnings per share because the exercise prices exceeded the average market value of the common shares of Cdn$26.46 (six months - Cdn$26.01), compared to Cdn$27.46 (six months - Cdn$27.48) for the comparable period in 2017.

1) Subject to an annual inflationary adjustment with the exception of Loma de La Plata and Sudbury.

2) All amounts are measured on a per ounce basis with the exception of cobalt which is measured on a per pound basis. Should the prevailing market price for the applicable metal be lower than this amount, the per ounce or per pound 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 $4.35 per ounce, subject to an annual inflationary factor.

3) Under the terms of the San Dimas precious metal purchase agreement, 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.

4) The Company is committed to pay Glencore 20% of the spot price of silver for each ounce of silver delivered under the Antamina silver purchase agreement.

5) Gold recoveries will be set at 55% for the Constancia deposit and 70% for the Pampacancha deposit until 265,000 ounces of gold have been delivered to the Company.

6) Subject to an increase to $9.90 per ounce of silver and $550 per ounce of gold after the initial 40-year term.

7) 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 life of mine.

8) The Company is committed to pay Sabanye 18% of the spot price of gold and palladium for each ounce of gold and palladium delivered under the Stillwater precious metal purchase agreement until such time as the upfront cash payment is reduced to $NIL and 22% of the spot price thereafter.

9) Once the Company has received 31 million pounds of cobalt, the Company’s attributable cobalt production to be purchased will be reduced to 21.2%.

10) The Company is committed to pay Vale 18% of the spot price of cobalt per pound of cobalt delivered under the agreement until such time as the upfront cash payment is reduced to $NIL, and 22% of the spot price thereafter.

11) Wheaton is committed to purchase from Glencore a per annum amount equal to the first 1.5 million ounces of payable silver produced at Yauliyacu and 50% of any excess.

12) Should the market price of silver exceed $20 per ounce, in addition to the $8.85 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 $18.85 per ounce of silver delivered.

13) In October 2015, in order to incentivize additional exploration and potentially extend the limited remaining mine life of Stratoni, Wheaton and Eldorado Gold agreed to modify the Stratoni silver purchase agreement. The primary modification is to increase the production price per ounce of silver delivered to Wheaton over the current fixed price by one of the following amounts: (i) $2.50 per ounce of silver delivered if 10,000 meters of drilling is completed outside of the existing ore body and within Wheaton’s defined area of interest (“Expansion Drilling”); (ii) $5.00 per ounce of silver delivered if 20,000 meters of Expansion Drilling is completed; and (iii) $7.00 per ounce of silver delivered if 30,000 meters of Expansion Drilling is completed. Drilling in all three cases must be completed by December 31, 2020, in order for the agreed upon increase in production price to be initiated. The figures in the above table reflect the fact that Eldorado completed 10,000 meters of Expansion Drilling in July 2018.

14) The Company is committed to acquire 100% of the first 30,000 ounces of gold produced per annum and 50% thereafter.

15) The production payment per ounce of gold delivered to Wheaton is to be increased over the current fixed price in periods where the market price of copper is lower than $2.50 per pound.

16) Wheaton only has the rights to silver contained in concentrate containing less than 15% copper at the Aljustrel mine.

17) During the second quarter of 2018, the Company agreed to amend the precious metal purchase agreement with Almina to increase the production payments to 50% of the amount received under the respective concentrate sales contracts and to fix silver payable rates for a period of two years and limit rate decreases thereafter.

18) The production payment related to the Keno Hill silver interest is a function of the silver head grade and silver spot price in the month in which the silver is produced.

19) Terms of the agreement not yet finalized.

20) Once 90 million silver equivalent ounces attributable to Wheaton have been produced, the attributable production to be purchased will decrease to 66.67% of silver production and 16.67% of gold production for the life of mine.

21) 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 silver and gold production for the life of mine.

22) The Company is committed to pay Kutcho 20% of the spot price of silver and gold for each ounce of silver and gold delivered under the Kutcho Early Deposit Agreement.

Stillwater

On July 25, 2018, in connection with the Stillwater precious metal purchase agreement (Note 27), the Company paid to Sibanye a total upfront cash payment of $500 million.

Taxes

2013 Taxation Year: Domestic

On July 24, 2018, the Company received a Notice of Reassessment for the 2013 taxation year (“the 2013 Domestic Reassessment”) 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 in respect of 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 basis over the estimated recoverable reserves, and where applicable, resources and exploration potential at the respective mine. The Company’s position, as reflected in its filed Canadian income tax returns, is 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, as provided for in the PMPAs.

Management believes the Company’s position is the correct one, and that it has filed its tax returns and paid applicable taxes in compliance with Canadian tax law. Wheaton intends to file a notice of objection within the 90-day period required under the Income Tax Act (Canada) (the “Act”) challenging the 2013 Domestic Reassessment. Even if the Company is unsuccessful in defending its position, it would not result in any additional tax for the 2013 taxation year after applying non-capital losses carried back from subsequent taxation years. However, interest and penalties of approximately $0.7 million (Cdn$0.9 million) remain owing (calculated to the date of the 2013 Domestic Reassessment), 50% of which must be paid in order to object to the 2013 Domestic Reassessment.

The CRA is conducting a domestic audit for the 2014 and 2015 taxation years. The 2016 and 2017 taxation years remain open to a domestic audit. If CRA were to reassess the Company’s Canadian PMPAs for the 2014-2017 taxation years on the same basis as CRA has reassessed the Company in the 2013 Domestic Reassessment, the Company estimates that it would not result in a material amount of additional tax, interest, and penalties.

2005 – 2010 Taxation Years: Canada Revenue Agency Dispute

On September 24, 2015, the Company received Notices of Reassessment (the “Reassessments”) from the CRA totaling $268 million (Cdn$353 million) for federal and provincial tax, transfer pricing penalties, interest and other penalties for the 2005-2010 taxation years. The CRA’s position in the Reassessments is that the transfer pricing provisions of the Act relating to income earned by the Company’s foreign subsidiaries outside of Canada should apply such that the income of Wheaton subject to tax in Canada should be increased by an amount equal to substantially all of the income earned outside of Canada by the Company’s foreign subsidiaries for the 2005-2010 taxation years. Management believes that the Company has filed its tax returns and paid applicable taxes in compliance with Canadian tax law, and as a result no amounts have been recorded for any potential liability arising from this matter. Wheaton is vigorously defending its tax filing positions.

On January 8, 2016, the Company commenced an appeal in the Tax Court of Canada. The Company was required to make a deposit of 50% of the reassessed amounts of tax, interest and penalties. Instead of making this deposit in cash, on March 15, 2016, the Company posted security in the form of a letter of guarantee in the amount of $146 million (Cdn$192 million), which included interest accrued to March 2016 plus estimated interest for the following year. In March 2017 and 2018, additional letters of guarantee in the amounts of $8 million (Cdn$11 million) and $8 million (Cdn$10 million), respectively, were delivered to the CRA as security for additional estimated interest for the respective following year. The Company is currently in the discovery phase of the appeal, with a trial scheduled to commence mid-September 2019 for a two month period.

2011 – 2015 Taxation Years: Audit of International Transactions

The CRA has also commenced an audit of the Company’s international transactions covering the 2011-2015 taxation years, which is currently ongoing. The Company has not received any proposal or notices of reassessment for the 2011-2015 taxation years in connection with this audit.

For ease of reference, the following provides an overview of the current status of CRA matters relating to income earned by the Company’s foreign subsidiaries outside of Canada:

Taxation Years	CRA Position/Status	Potential Income Inclusion	Potential Income Tax Payable (1)	Payments Made	Timing
2005-2010	Transfer pricing provisions of the Act should apply such that Wheaton’s income subject to tax in Canada should be increased by an amount equal to substantially all of the income earned outside of Canada by Wheaton’s foreign subsidiaries.	CRA has reassessed Wheaton and is seeking to increase Wheaton’s income subject to tax in Canada by Cdn$715 million.	CRA has reassessed Wheaton and is seeking to impose income tax of $153 million (Cdn$201 million).(2),(3)	Wheaton has posted security in the form of letters of guarantee totaling $162 million (Cdn$213 million) reflecting 50% of all assessed tax, penalties and interest accrued to March 15, 2019.(3),(4)	An appeal in the Tax Court of Canada commenced January 8, 2016. Trial scheduled to commence mid-September 2019 for a two month period.
2011-2015	CRA commenced an audit of 2011-2015 taxation years. CRA has not issued a proposal or reassessment.	If CRA were to reassess on a similar basis as 2005-2010 taxation years, the Company estimates CRA would seek to increase Wheaton’s income subject to tax in Canada by approximately $1.9 billion.(5), (8)	If CRA were to reassess on a similar basis as 2005-2010 taxation years, the Company estimates CRA would seek to impose income tax of approximately $384 million (Cdn$505 million).(5), (6), (8)	N/A	Time to complete CRA audit unknown.
2016-2017	Remains open to audit by CRA.	If CRA were to audit and then reassess on a similar basis as 2005-2010 taxation years, the Company estimates CRA would seek to increase Wheaton’s income subject to tax in Canada by approximately $580 million.(5), (8)	If CRA were to reassess on a similar basis as 2005-2010 taxation years, the Company estimates CRA would seek to impose income tax of approximately $149 million (Cdn$197 million).(5),(7),(8)	N/A	N/A

1) For the taxation years ended after December 31, 2010, the Company files its Canadian tax returns in US dollars. However, taxes payable, if any, are payable in Canadian dollars based on the exchange rate applicable on the original payment due date. As a result, the US dollar amounts reflected in the table above are subject to fluctuations in the value of the Canadian dollar relative to the US dollar. Canadian dollar amounts in this table have been converted to US dollars at the exchange rate applicable at the balance sheet date as quoted by the Bank of Canada.

2) For the 2005-2010 taxation years, transfer pricing penalties of $54 million (Cdn$72 million) and interest and other penalties of $61 million (Cdn$81 million) were also assessed by the CRA. The total reassessment issued on September 24, 2015 was $268 million (Cdn$353 million). Additional interest accruing to December 31, 2017 on the total amount reassessed is estimated at $34 million (Cdn$45 million) for the 2005-2010 taxation years.

3) As a consequence of the CRA’s reassessment of the 2005-2010 taxation years and the 2013 Domestic Reassessment, CRA reassessed the 2011 and 2012 taxation years to amend the non-capital losses available to offset the taxable income of $12 million and $14 million, respectively. As a result of the 2013 Domestic Reassessment, additional tax, interest, and penalties of about $1.6 million (Cdn$2.2 million) was owing for the 2011 and 2012 taxation years. The Company will be filing Notices of Objection with respect to these reassessments and accordingly, the Company will be required to pay 50% of the additional amounts owing. These reassessments do not relate to the CRA international audit of the 2011-2015 taxation years.

4) Estimates of interest given as of the date stated. Interest accrues until payment date.

5) The estimates of income inclusion and tax payable are computed on the basis that the cost of precious metal acquired under the PMPAs is equal to the cash cost plus an amortized amount of the up-front payment and without taking into account any available Canadian non-capital losses.

6) If CRA were to reassess the 2011-2015 taxation years and continue to apply transfer pricing penalties, management estimates that transfer pricing penalties of approximately $187 million and interest (calculated to December 31, 2017) and other penalties of approximately $110 million (Cdn$145 million) may be applicable for the 2011-2015 taxation years.

7) If CRA were to reassess the 2016-2017 taxation years and continue to apply transfer pricing penalties, management estimates that transfer pricing penalties of approximately $58 million and interest (calculated to December 31, 2017) and other penalties of approximately $9 million (Cdn$12 million) may be applicable for the 2016-2017 taxation years.

8) If the cost of precious metal acquired under the PMPAs is equal to the market value of precious metal while the deposit is outstanding (where applicable to an agreement), and the cash cost thereafter, the estimated amounts for the 2011 – 2015 taxation years would be as follows: (i) income inclusion of $1.6 billion; (ii) tax payable of $331 million (Cdn$435 million); (iii) transfer pricing penalties (if applied) of $161 million; and (iv) interest and other penalties of $93 million (Cdn$123 million). On this basis, the estimated amounts for the 2016 – 2017 taxation years would be as follows: (i) income inclusion of $260 million; (ii) tax payable of $68 million (Cdn$89 million); (iii) transfer pricing penalties (if applied) of $26 million; and (iv) interest and other penalties of $4 million (Cdn$6 million).

U.S. Shareholder Class Action

During July 2015, after the Company disclosed that the CRA was proposing that they would issue the Reassessments, two putative securities class action lawsuits were filed against the Company in the U.S. District Court for the Central District of California in connection with the Proposal (the “Complaints”).

On October 19, 2015, the Complaints were consolidated into one action, In re Silver Wheaton Securities Litigation, as against the Company, Randy Smallwood, President & Chief Executive Officer, Gary Brown, Senior Vice President & Chief Financial Officer and Peter Barnes, former Chief Executive Officer (together the “Defendants”) and a lead plaintiff (the “Plaintiff”) was selected. The Plaintiff filed a consolidated amended complaint in December 2015, and then filed a second amended complaint in April 2018 (the “Amended Complaint”). The Amended Complaint alleges, among other things, that the Defendants made false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, prospects and performance in violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Specifically, the Amended Complaint focuses on the Reassessments. The Amended Complaint purports to be brought on behalf of persons who purchased or otherwise acquired the Company’s securities in the United States during an alleged class period of March 30, 2011 to July 6, 2015.

At a hearing on June 6, 2016, the Court denied the Defendants’ motion to dismiss. A denial of such a motion is not a ruling on the merits of the claims in the lawsuit. Certification of the class was granted by the Court on May 11, 2017. Defendants have filed motions to dismiss the second amended complaint and a hearing is set for November 2018. No trial date is currently set for this matter.

The Company believes the allegations are without merit and intends to vigorously defend against this matter. No amounts have been recorded for any potential liability arising from this matter, as the original Complaints do not specify a quantum of damages and the Company cannot reasonably predict the outcome.

Canadian Shareholder Class Action

By Notice of Action dated August 10, 2016 (as amended September 2, 2016), 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 statement of claim filed alleges, among other things, misrepresentation pursuant to primary and secondary market civil liability provisions under the Securities Act (Ontario), common law negligence and negligent misrepresentation. The claim focuses on the Reassessments. The statement of claim purports to be brought on behalf of persons who (i) acquired Wheaton common shares in Wheaton’s March 2015 public offering, and (ii) acquired Wheaton common shares in the secondary market, other than in the United States, during an alleged class period of August 14, 2013 to July 6, 2015 inclusive.

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.

Other

Due to the size, complexity and nature of the Company’s operations, various legal and tax matters are outstanding from time to time. 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.

Declaration of Dividend

On August 14, 2018, the Board of Directors declared a dividend in the amount of $0.09 per common share as per the Company’s stated dividend policy whereby the quarterly dividend will be equal to 30% of the average of the operating cash flow of the previous four quarters. This dividend is payable to shareholders of record on August 29, 2018 and is expected to be distributed on or about September 13, 2018. 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 3% of the Average Market Price, as defined in the DRIP.

Acquisition of Stillwater Mineral Stream Interest

On July 16, 2018, the Company announced that it had entered into an agreement with Sibanye to acquire an amount of gold and palladium equal to a fixed percentage of production from the Stillwater and East Boulder mines located in Montana in the United States (collectively referred to as the “Stillwater” mines) for a total upfront cash payment of $500 million. Deliveries under the agreement will begin July 1, 2018 at a fixed payable rate of 99% for gold and 99.6% for palladium.

Under the terms of the agreement, the Company has acquired an amount of gold equal to 100% of the gold production for the life of the mine and an amount of palladium equal to 4.5% of the palladium production until 375,000 ounces of palladium have been delivered to Wheaton, after which the Company’s entitlement will be reduced to 2.25% of the palladium production until 550,000 ounces of palladium have been delivered to Wheaton, after which the Company’s entitlement will be reduced to 1.00% of the palladium production for the life of mine.

In addition to the initial upfront cash consideration, the Company will make ongoing payments of 18% of the spot price of gold and palladium for each ounce of gold and palladium delivered under the agreement until the net market value of gold and palladium delivered to Wheaton exceeds the initial upfront cash deposit, and 22% of the spot price thereafter¹.

Acquisition of Adventus Zinc Corporation Shares

On July 17, 2018, the Company acquired 7,093,392 common shares of Adventus Zinc Corporation (“Adventus”) in a private placement transaction, for total consideration of Cdn$6 million, representing 9.99% of Adventus’ issued and outstanding common shares.

Basis of Presentation

2. Basis of Presentation

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”). 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, 2017 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, 2017.

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, 2018 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.

IFRS 9 - Financial Instruments (amended 2014)

IFRS 9 – Financial Instruments (amended 2014):

On January 1, 2018, the Company adopted IFRS 9 (2014) – Financial Instruments (amended 2014) (“IFRS 9 (2014)”). The Company had previously adopted IFRS 9 (2009) – Financial Instruments effective January 1, 2010. The adoption of IFRS 9 (2014) did not materially impact the accounting policies and methods of application relative to the Company’s financial instruments.

IFRS 15 - Revenue from Contracts with Customers

IFRS 15 – Revenue from Contracts with Customers:

On January 1, 2018, the Company adopted IFRS 15 – Revenue from Contracts with Customers (“IFRS 15”) which supersedes IAS 18 – Revenue (“IAS 18”). IFRS 15 establishes a single five-step model framework for determining the nature, amount, timing and uncertainty of revenue and cash flows arising from a contract with a customer. The standard is effective for annual periods beginning on or after January 1, 2018. IFRS 15 requires entities to recognize revenue when ‘control’ of goods or services transfers to the customer whereas the previous standard, IAS 18, required entities to recognize revenue when the ‘risks and rewards’ of the goods or services transfer to the customer. The Company concluded that there is no change in the timing of revenue recognition of its silver and gold credit sales and its silver and gold concentrate sales under IFRS 15 compared to the previous standard as the point of transfer of risks and rewards of the silver and gold and the transfer of control of the silver and gold occur at the same time. As such, no adjustment was required to the Company’s consolidated financial statements as at January 1, 2017 or for the year ended December 31, 2017. Additionally, IFRS 15 requires that variable consideration should only be recognized to the extent that it is highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur. The Company concluded that the adjustments relating to the final assay results for the quantity of concentrate sold under the terms of the concentrate sales contracts are not significant and do not constrain the recognition of revenue.

Future Changes in Accounting Policies

3.2. Future Changes in Accounting Policies

The IASB has issued the following new or amended standards:

Standards required to be applied for periods beginning on or after January 1, 2019:

• IFRS 16 – Leases: In January 2016, the IASB and the FASB completed its joint project to address concerns by users of financial statements in respect of reduced comparability between financial statements due to the different accounting treatment applied to operating leases as compared to finance leases by removing the distinction between operating leases and finance leases and rather having all leases accounted for as a finance lease, subject to limited exceptions for short-term leases and leases of low value assets. The Company is currently evaluating the impact of this standard and anticipates that upon adoption of this standard, its leases will be capitalized under the classification Right-of-Use Assets, with a corresponding liability for Leases Payable. The total amount to be capitalized is estimated to be $3 million. The Company also expects a reduction in operating cash outflows of approximately $1 million per annum upon the adoption of IFRS 16, with a corresponding increase in financing cash outflows. Lastly, the Company does not anticipate the adoption of this standard will have a material impact on its Consolidated Statement of Earnings.

• IFRIC 23 – Uncertainty over Income Tax Treatments: In June 2017, the IASB issued IFRIC 23 which is effective for periods beginning on or after January 1, 2019. IFRIC 23 provides guidance on the accounting for current and deferred tax liabilities and assets in circumstances in which there is uncertainty over income tax treatments. The extent of the impact of the adoption of IFRIC 23 has not yet been determined.

Early adoption of the above standards is permitted.

1) Includes cumulative impairment charges to December 31, 2017 as follows: Keno Hill silver interest - $11 million; Pascua-Lama silver interest - $338 million; 777 silver interest - $64 million; 777 gold interest - $151 million; and Sudbury gold interest - $120 million.

2) On March 29, 2017, the Company amended its silver purchase agreement with Alexco Resource Corp. (“Alexco”) to adjust the silver production payment so that it will be a percentage of the spot silver price that increases with lower mill silver head grades and lower silver prices, and decreases with higher mill silver head grades and higher silver prices, subject to certain ceiling and floor grades and prices. In addition, the outside completion date was extended to December 31, 2019 and the area of interest was expanded to include properties currently owned by Alexco and properties acquired by Alexco in the future which fall within a one kilometer radius of existing Alexco holdings in the Keno Hill Silver District. As consideration, on April 10, 2017, Alexco issued 3 million shares to Wheaton which had a fair value of $5 million. The fair value of these shares have been reflected as a reduction to the cost base of the Keno Hill silver interest.

3) Comprised of the Los Filos, Zinkgruvan, Yauliyacu, Stratoni, Keno Hill, Cozamin, Neves-Corvo, Minto, Aljustrel, Loma de La Plata, Pascua-Lama, Lagunas Norte, Pierina, Veladero, Rosemont and 777 silver interests. The Cozamin precious metal purchase agreement expired on April 4, 2017 and the fully depleted value of this contract has been reflected as a disposal.

4) Comprised of the Coleman, Copper Cliff, Garson, Stobie, Creighton, Totten and Victor gold interests.

5) Comprised of the Minto, Rosemont and 777 gold interests.

1) Subject to an annual inflationary adjustment with the exception of Loma de La Plata and Sudbury.

2) All amounts are measured on a per ounce basis with the exception of cobalt which is measured on a per pound basis. Should the prevailing market price for the applicable metal be lower than this amount, the per ounce or per pound 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 $4.35 per ounce, subject to an annual inflationary factor.

3) Under the terms of the San Dimas precious metal purchase agreement, 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.

4) The Company is committed to pay Glencore 20% of the spot price of silver for each ounce of silver delivered under the Antamina silver purchase agreement.

5) Gold recoveries will be set at 55% for the Constancia deposit and 70% for the Pampacancha deposit until 265,000 ounces of gold have been delivered to the Company.

6) Subject to an increase to $9.90 per ounce of silver and $550 per ounce of gold after the initial 40-year term.

7) 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 life of mine.

8) The Company is committed to pay Sabanye 18% of the spot price of gold and palladium for each ounce of gold and palladium delivered under the Stillwater precious metal purchase agreement until such time as the upfront cash payment is reduced to $NIL and 22% of the spot price thereafter.

9) Once the Company has received 31 million pounds of cobalt, the Company’s attributable cobalt production to be purchased will be reduced to 21.2%.

10) The Company is committed to pay Vale 18% of the spot price of cobalt per pound of cobalt delivered under the agreement until such time as the upfront cash payment is reduced to $NIL, and 22% of the spot price thereafter.

11) Wheaton is committed to purchase from Glencore a per annum amount equal to the first 1.5 million ounces of payable silver produced at Yauliyacu and 50% of any excess.

12) Should the market price of silver exceed $20 per ounce, in addition to the $8.85 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 $18.85 per ounce of silver delivered.

13) In October 2015, in order to incentivize additional exploration and potentially extend the limited remaining mine life of Stratoni, Wheaton and Eldorado Gold agreed to modify the Stratoni silver purchase agreement. The primary modification is to increase the production price per ounce of silver delivered to Wheaton over the current fixed price by one of the following amounts: (i) $2.50 per ounce of silver delivered if 10,000 meters of drilling is completed outside of the existing ore body and within Wheaton’s defined area of interest (“Expansion Drilling”); (ii) $5.00 per ounce of silver delivered if 20,000 meters of Expansion Drilling is completed; and (iii) $7.00 per ounce of silver delivered if 30,000 meters of Expansion Drilling is completed. Drilling in all three cases must be completed by December 31, 2020, in order for the agreed upon increase in production price to be initiated. The figures in the above table reflect the fact that Eldorado completed 10,000 meters of Expansion Drilling in July 2018.

14) The Company is committed to acquire 100% of the first 30,000 ounces of gold produced per annum and 50% thereafter.

15) The production payment per ounce of gold delivered to Wheaton is to be increased over the current fixed price in periods where the market price of copper is lower than $2.50 per pound.

16) Wheaton only has the rights to silver contained in concentrate containing less than 15% copper at the Aljustrel mine.

17) During the second quarter of 2018, the Company agreed to amend the precious metal purchase agreement with Almina to increase the production payments to 50% of the amount received under the respective concentrate sales contracts and to fix silver payable rates for a period of two years and limit rate decreases thereafter.

18) The production payment related to the Keno Hill silver interest is a function of the silver head grade and silver spot price in the month in which the silver is produced.

19) Terms of the agreement not yet finalized.

20) Once 90 million silver equivalent ounces attributable to Wheaton have been produced, the attributable production to be purchased will decrease to 66.67% of silver production and 16.67% of gold production for the life of mine.

21) 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 silver and gold production for the life of mine.

22) The Company is committed to pay Kutcho 20% of the spot price of silver and gold for each ounce of silver and gold delivered under the Kutcho Early Deposit Agreement.

Summary of Current Status of CRA

For ease of reference, the following provides an overview of the current status of CRA matters relating to income earned by the Company’s foreign subsidiaries outside of Canada:

Taxation Years	CRA Position/Status	Potential Income Inclusion	Potential Income Tax Payable (1)	Payments Made	Timing
2005-2010	Transfer pricing provisions of the Act should apply such that Wheaton’s income subject to tax in Canada should be increased by an amount equal to substantially all of the income earned outside of Canada by Wheaton’s foreign subsidiaries.	CRA has reassessed Wheaton and is seeking to increase Wheaton’s income subject to tax in Canada by Cdn$715 million.	CRA has reassessed Wheaton and is seeking to impose income tax of $153 million (Cdn$201 million).(2),(3)	Wheaton has posted security in the form of letters of guarantee totaling $162 million (Cdn$213 million) reflecting 50% of all assessed tax, penalties and interest accrued to March 15, 2019.(3),(4)	An appeal in the Tax Court of Canada commenced January 8, 2016. Trial scheduled to commence mid-September 2019 for a two month period.
2011-2015	CRA commenced an audit of 2011-2015 taxation years. CRA has not issued a proposal or reassessment.	If CRA were to reassess on a similar basis as 2005-2010 taxation years, the Company estimates CRA would seek to increase Wheaton’s income subject to tax in Canada by approximately $1.9 billion.(5), (8)	If CRA were to reassess on a similar basis as 2005-2010 taxation years, the Company estimates CRA would seek to impose income tax of approximately $384 million (Cdn$505 million).(5), (6), (8)	N/A	Time to complete CRA audit unknown.
2016-2017	Remains open to audit by CRA.	If CRA were to audit and then reassess on a similar basis as 2005-2010 taxation years, the Company estimates CRA would seek to increase Wheaton’s income subject to tax in Canada by approximately $580 million.(5), (8)	If CRA were to reassess on a similar basis as 2005-2010 taxation years, the Company estimates CRA would seek to impose income tax of approximately $149 million (Cdn$197 million).(5),(7),(8)	N/A	N/A

1) For the taxation years ended after December 31, 2010, the Company files its Canadian tax returns in US dollars. However, taxes payable, if any, are payable in Canadian dollars based on the exchange rate applicable on the original payment due date. As a result, the US dollar amounts reflected in the table above are subject to fluctuations in the value of the Canadian dollar relative to the US dollar. Canadian dollar amounts in this table have been converted to US dollars at the exchange rate applicable at the balance sheet date as quoted by the Bank of Canada.

2) For the 2005-2010 taxation years, transfer pricing penalties of $54 million (Cdn$72 million) and interest and other penalties of $61 million (Cdn$81 million) were also assessed by the CRA. The total reassessment issued on September 24, 2015 was $268 million (Cdn$353 million). Additional interest accruing to December 31, 2017 on the total amount reassessed is estimated at $34 million (Cdn$45 million) for the 2005-2010 taxation years.

3) As a consequence of the CRA’s reassessment of the 2005-2010 taxation years and the 2013 Domestic Reassessment, CRA reassessed the 2011 and 2012 taxation years to amend the non-capital losses available to offset the taxable income of $12 million and $14 million, respectively. As a result of the 2013 Domestic Reassessment, additional tax, interest, and penalties of about $1.6 million (Cdn$2.2 million) was owing for the 2011 and 2012 taxation years. The Company will be filing Notices of Objection with respect to these reassessments and accordingly, the Company will be required to pay 50% of the additional amounts owing. These reassessments do not relate to the CRA international audit of the 2011-2015 taxation years.

4) Estimates of interest given as of the date stated. Interest accrues until payment date.

5) The estimates of income inclusion and tax payable are computed on the basis that the cost of precious metal acquired under the PMPAs is equal to the cash cost plus an amortized amount of the up-front payment and without taking into account any available Canadian non-capital losses.

6) If CRA were to reassess the 2011-2015 taxation years and continue to apply transfer pricing penalties, management estimates that transfer pricing penalties of approximately $187 million and interest (calculated to December 31, 2017) and other penalties of approximately $110 million (Cdn$145 million) may be applicable for the 2011-2015 taxation years.

7) If CRA were to reassess the 2016-2017 taxation years and continue to apply transfer pricing penalties, management estimates that transfer pricing penalties of approximately $58 million and interest (calculated to December 31, 2017) and other penalties of approximately $9 million (Cdn$12 million) may be applicable for the 2016-2017 taxation years.

8) If the cost of precious metal acquired under the PMPAs is equal to the market value of precious metal while the deposit is outstanding (where applicable to an agreement), and the cash cost thereafter, the estimated amounts for the 2011 – 2015 taxation years would be as follows: (i) income inclusion of $1.6 billion; (ii) tax payable of $331 million (Cdn$435 million); (iii) transfer pricing penalties (if applied) of $161 million; and (iv) interest and other penalties of $93 million (Cdn$123 million). On this basis, the estimated amounts for the 2016 – 2017 taxation years would be as follows: (i) income inclusion of $260 million; (ii) tax payable of $68 million (Cdn$89 million); (iii) transfer pricing penalties (if applied) of $26 million; and (iv) interest and other penalties of $4 million (Cdn$6 million).
