Overview

Wheaton Precious Metals Corp. is a precious metal streaming company which generates its revenue primarily from the sale of precious metals (gold, silver and palladium) and cobalt. The Company is listed on the New York Stock Exchange ("NYSE"), the Toronto Stock Exchange ("TSX") and the London Stock Exchange ("LSE") and trades under the symbol WPM.

Including the proposed Hemlo PMPA, which is expected to close in Q4-2025, the Company has 41 long-term agreements¹ (33 of which are precious metal purchase agreements, or "PMPAs", three of which are early deposit PMPAs, and five of which are royalty agreements), with 34 different mining companies, related to precious metals and cobalt relating to 23 mining assets which are currently operating, 22 of which are at various stages of development and 2 which have been placed into care and maintenance or have been closed, located in 18 countries. Pursuant to the PMPAs, Wheaton acquires metal production from the counterparties for an initial upfront payment plus an additional cash payment for each ounce or pound delivered which is fixed by contract, generally at or below the prevailing market price. Attributable metal production as referred to in this MD&A is the metal production to which Wheaton is entitled pursuant to the various PMPAs. During the three months ended September 30, 2025, the per ounce price paid by the Company for the metals acquired under the agreements averaged \$515 for gold, \$6.35 for silver, \$205 for palladium and \$3.44 per pound for cobalt. The primary drivers of the Company's financial results are the volume of metal production at the various mining assets to which the PMPAs relate and the price realized by Wheaton upon the sale of the metals received. Throughout this MD&A, the production and sales volume of gold, silver and palladium are reported in ounces, while cobalt is reported in pounds. ¹

1 Minto has been removed from the mine count due to Minto Metals Corp. being placed in receivership.

¹⁾ All amounts in thousands except gold and palladium ounces produced and sold, per ounce amounts and per share amounts.

2) Gold-equivalent ounces ("GEOs"), which are provided to assist the reader, are based on the following commodity price assumptions: \$2,600 per ounce gold; \$30.00 per

ounce silver; \$950 per ounce palladium; and \$13.50 per pound cobalt; consistent with those used in estimating the Company's production guidance for 2025.

³⁾ Represents the increase (decrease) in payable ounces produced but not delivered ("PBND") relative to the various mines that the Company derives precious metal from and, for cobalt, the increase (decrease) of payable pounds PBND. Payable units PBND will be recognized in future sales as they are delivered to the Company under the terms of their contracts. Payable ounces PBND to Wheaton is expected to average approximately two to three months of annualized production for both gold and palladium and two months for silver but may vary from quarter to quarter due to a number of factors, including mine ramp-up and the timing of shipments.

Highlights

Operations

For the three months ended September 30, 2025, relative to the comparable period of the prior year:
o Production amounted to 173,400 gold equivalent ounces ("GEOs"), an increase of 22%, primarily due to higher production at Salobo and Antamina, coupled with the commencement of production at Blackwater.
o Sales volumes amounted to 137,600 GEO's, an increase of 13%, a result of the higher production partially offset by an increase in the number of GEOs produced but not delivered ("PBND"). PBND increased by 21,000 GEOs during the quarter and represents approximately 2.9 months of production, compared to 2.7 months in the previous quarter, reflecting normal variations in shipment timing and delivery cycles.
o Revenue increased 55% or \$168 million to \$476 million (58% gold, 39% silver, 1% palladium and 2% cobalt), with the increase being primarily due to a 37% increase in realized commodity prices coupled with the higher sales volumes.
o Gross margin amounted to \$336 million (71% of revenue), representing an increase of \$139 million (a 7% increase as a percentage of revenue). The higher margin as a percentage of revenue reflects the leverage provided by fixed per-ounce production payments, which accounted for 76% of revenue during the quarter.
o Net earnings amounted to \$367 million, an increase of \$213 million, primarily due to the increased gross margin coupled with an \$86 million pre-tax gain from the exercise of the 33% buy-back option under the Cangrejos PMPA in connection with CMOC Group Limited's ("CMOC") acquisition of Lumina Gold Corp. ("Lumina"). This gain contributed \$73 million to net earnings after tax.
o Adjusted net earnings increased 84% or \$128 million to \$281 million.
o Operating cash flow amounted to \$383 million, with the \$129 million increase being the result of the higher gross margin.
For the nine months ended September 30, 2025 relative to the prior year:
o Production amounted to 483,500 GEOs, an increase of 8%, with increased production from Salobo and Antamina coupled with the commencement of production at Blackwater being partially offset by lower production at Constancia and Peñasquito.
o Sales volumes amounted to 460,800 GEOs, an increase of 19% resulting from higher production and relative changes in the number of GEOs PBND, with PBND decreasing by 16,500 GEOs, compared to a 17,600 GEO increase during the comparable period of the prior year.
o Revenue increased 60% or \$546 million to \$1.4 billion (64% gold, 34% silver, 1% palladium and 1% cobalt), representing a record for the Company, with the increase being primarily due to a 35% increase in realized commodity prices coupled with the 19% increase in sales volumes.
o Gross margin amounted to \$1 billion (70% of revenue), representing an increase of \$453 million (an 8% increase as a percentage of revenue).
o Net earnings amounted to \$913 million, an increase of \$472 million, primarily due to the higher gross margin coupled with the gain from the exercise of the 33% buy-back option under the Cangrejos PMPA, partially offset by higher income taxes.
o Adjusted net earnings increased 85% or \$377 million to \$818 million, representing a record for the Company.
o Operating cash flow amounted to \$1.2 billion, representing a record for the Company, with the \$451 million increase being due primarily to the higher gross margin.
On November 6, 2025, the Board of Directors declared a dividend in the amount of \$0.165 per common share.

Corporate Development

On September 10, 2025, the Company entered into a financing commitment with Carcetti Capital Corporation ("Carcetti") to support Carcetti's proposed acquisition of the currently operating Hemlo mine from Barrick Mining Corporation, including a gold stream of up to \$400 million, with Carcetti expected to elect an amount of \$300 million in accordance with the terms of the agreement. The transaction is expected to close in Q4 2025, delivering immediate production and cash flow to the Company. In addition, the Company invested \$30 million (Cdn\$42 million) in Carcetti's equity offering.

In connection with its acquisition of Lumina, CMOC exercised its 33% buy-back option under the Cangrejos PMPA for a cash payment of \$102 million. Wheaton had previously paid an upfront amount of \$16 million attributable to this portion of the stream. The transaction resulted in a gain of \$86 million.
On October 8, 2025, the Company amended its PMPA with BMC Minerals Ltd. ("BMC") in respect of the Kudz Ze Kayah ("KZK") project, with the amendment including the elimination of BMC Minerals' one-time option to repurchase 50% of the stream for a period of 30 days after June 22, 2026 and the Company's right to repayment on certain conditions being met. In connection with the amendment, the Company advanced an additional upfront deposit of \$2.5 million to BMC at the time of execution and has committed to advance an additional \$15 million deposit on KZK achieving certain permitting milestones.

Other

During the third quarter of 2025:
o The Company paid a quarterly dividend of \$75 million.
o The Company made total upfront cash payments of \$250 million relative to the Koné PMPA (\$156 million), the Fenix PMPA (\$50 million), and the Kurmuk PMPA (\$44 million).
o The Company updated its life of mine estimates including its recoverable reserves, resources, and exploration potential at each mining operation as part of its normal course procedures. As a result, revised depletion rates for each operating mining asset were reflected in the current quarter and will be applied prospectively.
Subsequent to the quarter, the Company made additional upfront cash payments of \$94 million relative to the Fenix PMPA (\$50 million) and the El Domo PMPA (\$44 million).

Outlook1

Wheaton's estimated attributable production in 2025 is forecast to be 350,000 to 390,000 ounces of gold, 20.5 to 22.5 million ounces of silver, and 12,500 to 13,500 GEOs of other metals, resulting in annual production of approximately 600,000 to 670,000 GEOs2, unchanged from previous guidance.

Annual production is forecast to increase by approximately 40% to 870,000 GEOs2 by 2029, with average annual production forecast to grow to over 950,000 GEOs2 in years 2030 to 2034, also unchanged from previous guidance.

Liquidity

The \$1.2 billion of cash and cash equivalents as at September 30, 2025 combined with the liquidity provided by the available credit under the \$2 billion revolving term loan ("Revolving Facility") with \$500 million accordion feature 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.

¹ Statements made in this section contain forward-looking information with respect to forecast production, funding outstanding commitments and continuing to acquire accretive mineral stream interests and readers are cautioned that actual outcomes may vary. Please see "Cautionary Note Regarding Forward-Looking Statements" for material risks, assumptions and important disclosure associated with this information.

Ounces produced represent the quantity of silver, gold, palladium, platinum and cobalt contained in concentrate or doré prior to smelting or refining deductions. Gold equivalent forecast production for 2025 and the longer-term outlook are based on the following updated commodity price assumptions: \$2,600 per ounce gold, \$30 per ounce silver, \$950 per ounce palladium, \$950 per ounce of platinum and \$13.50 per pound cobalt.

2) Please refer to the section entitled "Contractual Obligations and Contingencies Mineral Stream Interests" on page 32 of this MD&A for more information.
3) All figures in thousands except gold and palladium ounces and per ounce amounts. The total upfront consideration paid to date excludes closing costs and capitalized interest, where applicable. Please refer to the section entitled "Other Contractual Obligations and Contingencies" on page 34 of this MD&A for details of when the remaining upfront consideration is forecasted to be paid. Certain contracts, including Santo Domingo and El Domo, contain delay ounce provisions whereby should construction of the mine not be completed by an agreed to date, the mine operator must compensate the Company for the delay until certain conditions are satisfied by delivering additional ounces. The value of these ounces on the date first due, net of amounts owed to the mine operator, is treated as a reduction to the upfront consideration paid. Sale of the resulting ounces received is treated as revenue, with the associated cost of sales being equal to the fair value of the ounces on the date received.
4) Payable gold, silver, palladium and cobalt PBND are based on management estimates. These figures may be updated in the future as additional information is received. Please see "Cautionary Note Regarding Forward-Looking Statements" for material risks, assumptions and important disclosure associated with this information.
5) Comprised of the operating Coleman, Copper Cliff, Garson, Creighton, Stobie and Totten gold interests as well as the non-operating and Victor gold interest. As of September 30, 2025, the Company has received approximately \$350 million of operating cash flows from the Sudbury stream. Should the market value of gold delivered to Wheaton through the 20-year term of the contract, net of the per ounce cash payment, be lower than the initial \$670 million refundable deposit, the Company will be entitled to a refund of the difference at the conclusion of the term. The term of the Sudbury PMPA ends on May 11, 2033.
6) The original San Dimas SPA, entered into on October 15, 2004, was terminated on May 10, 2018 and concurrently the Company entered into the new San Dimas PMPA. 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. Effective April 30, 2025, the fixed gold to silver exchange ratio was revised from 70:1 to 90:1.
7) Comprised of the Stillwater and East Boulder gold and palladium interests.
8) Once the Company has received 464,000 ounces of gold under the amended Blackwater Gold PMPA, the attributable gold production will be reduced to 4%. Once the Company has received 17.8 million ounces of silver under the Blackwater Silver PMPA, the attributable silver production will be reduced to 33%.
9) Once the Company has received 218,750 ounces of gold under the Platreef Gold PMPA, the attributable gold production will reduce to 50% until 428,300 ounces have been delivered, after which the stream drops to 3.125%. Under the Platreef Palladium and Platinum PMPA, once the Company has received 350,000 ounces of combined palladium and platinum, the attributable palladium and platinum production will reduce to 3% until 485,115 ounces have been delivered, after which the stream drops to 0.1% of the payable palladium and platinum production. If certain thresholds are met, including if production through the Platreef project concentrator achieves 5.5 million tonnes per annum ("Mtpa"), the 3.125% residual gold stream and the 0.1% residual palladium and platinum stream will terminate. Under the Platreef Gold PMPA, a subsidiary of Royal Gold Inc. (formerly Sandstorm Gold Ltd./Nomad Royalty Ltd.) ("Royal Gold") is entitled to purchase 37.5% of payable gold. The decrease in the percentage of payable metal that Wheaton will be entitled to purchase is conditional on delivery of the total amount of payable gold to all purchasers (Wheaton and Royal Gold combined). The values set out herein pertain only to Wheaton's share of the payable gold.
10) Once the Company has received 310,000 ounces of gold and 2.15 million ounces of silver under the Marmato PMPA, the attributable gold and silver production will be reduced to 5.25% and 50%, respectively.

Under the revised agreement, the Company is entitled to purchase an additional 16% of payable gold production (22% in total) (subject to adjustment if there are delays in deliveries relative to an agreed schedule). Once Rio2 delivers the incremental 95,000 ounces (as adjusted), the stream reverts to the percentages and thresholds under the original Fenix PMPA (as described). Rio2 has a one-time option to terminate the requirement to deliver the incremental gold production from the end of 2027 until the end of 2029 by delivering 95,000 ounces (as adjusted) less previously delivered gold ounces, excluding those gold ounces which would have been delivered under the original Fenix PMPA.
13) Once the Company has received 145,000 ounces of gold under the El Domo PMPA, the attributable gold production will be reduced to 33%, and once the Company has received 4.6 million ounces of silver, the attributable silver production will be reduced to 50%. The units sold under El Domo relate to ounces received due to the delay ounce provision (see footnote 3, above).
14) Once the Company has received 150,000 ounces of gold and 120,000 ounces of platinum under the Marathon PMPA, the attributable gold and platinum production will be reduced to 67% and 15%.

The percentage of payable production and other key PMPA terms for all mineral stream interests are described in the Contractual Obligations and Contingencies section of this MD&A starting on page 32 of the MD&A.

Proposed Acquisition of Mineral Stream Interests

Hemlo

On September 10, 2025, the Company announced it has committed to enter into a financing commitment with Carcetti to support its proposed acquisition of the currently operating Hemlo mine from Barrick Mining Corporation, including a gold stream of up to \$400 million, subject to execution of definitive agreements and satisfaction of customary conditions. Under the terms of the proposed gold stream, Wheaton would purchase 13.5% of the payable gold until a total of 181,000 ounces of gold has been delivered, at which point Wheaton would purchase 9.0% of the payable gold until an additional 157,330 oz of gold has been delivered, after which Wheaton would purchase 6.0% of payable gold for the life of the mine. Each of the dropdown thresholds will be subject to adjustment if there are delays in deliveries relative to an agreed schedule, and commencing in 2033, if deliveries fall behind the agreed schedule by 10 Koz or more, the stream percentage will be increased by 5% until deliveries catch up with the agreed schedule. The applicable stream percentage will be reduced by half with respect to gold production from certain claims comprising the Interlake deposit. Additionally, Wheaton would make ongoing payments for the gold ounces delivered equal to 20% of the spot price of gold. Carcetti is expected to elect an amount of \$300 million in accordance with the terms of the agreement, in which case the stream percentages would be adjusted proportionately. The transaction is expected to close in Q4 2025, delivering immediate production and cash flow to the Company.

As part of its financing commitment, on October 7, 2025 the Company invested \$30 million (Cdn\$42 million) in Carcetti's equity offering.

Long-Term Equity Investments

The Company will, from time to time, invest in securities of companies for strategic purposes including, but not limited to, exploration and mining companies. The Company held the following investments as at September 30, 2025 and December 31, 2024:

	September 30	December 31
(in thousands)	2025	2024
Common shares held	\$ 262,412	\$ 98,190
Warrants held	1,970	785
Total long-term equity investments	\$ 264,382	\$ 98,975

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 LTI's but is reclassified to retained earnings.

While long-term investments in warrants are also held for long-term strategic purposes, they meet the definition of a derivative and therefore are classified as financial assets with fair value adjustments being recorded as a component of net earnings under the classification Other Income (Expense). Warrants that do not have a quoted market price are valued using a Black-Scholes option pricing model.

By holding these long-term investments, the Company is inherently exposed to various risk factors including currency risk, market price risk and liquidity risk.

A summary of the fair value of these equity investments and the fair value changes recognized as a component of the Company's OCI during the three and nine months ended September 30, 2025 and 2024 is presented below:

1) All figures in thousands except gold and palladium ounces produced.

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

6) There was a temporary suspension of operations at Peñasquito due to a labour strike which ran from June 7, 2023 to October 13, 2023.

8) On September 12, 2023, it was announced that the production of the zinc and lead concentrates at the Aljustrel mine will be halted from September 24, 2023 until the third quarter of 2025.

²⁾ Quantity produced represent the amount of gold, silver, palladium and cobalt contained in concentrate or doré prior to smelting or refining deductions. Production figures and payable rates are based on information provided by the operators of the mining operations to which the mineral stream interests relate or management estimates in those situations where other information is not available. Certain production figures and payable rates may be updated in future periods as additional information is received.

⁴⁾ 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. Effective April 30, 2025, the fixed gold to silver exchange ratio has been revised to 90:1. For reference, attributable silver production from prior periods is as follows: Q3 2025 - 364,000 ounces; Q2 2025 - 311,000 ounces; Q1 2025 - 340,000 ounces; Q4 2024 - 295,000 ounces; Q3 2024 - 262,000 ounces; Q2 2024 - 285,000 ounces; Q1 2024 - 291,000 ounces; Q4 2023 - 378,000 ounces.

⁵⁾ Comprised of the Stillwater and East Boulder gold and palladium interests. On September 12, 2024, Sibanye Stillwater ("Sibanye") announced that as a result of low palladium prices it was placing the Stillwater West operations into care and maintenance, while using Stillwater East and East Boulder operations to improve efficiencies that could get Stillwater West back to production as prices permit.

⁷⁾ On April 1, 2025, Equinox Gold Corp., ("Equinox") reported it has indefinitely suspended operations at Los Filos following the expiry of its land access agreement with the community of Carrizalillo on March 31, 2025.

⁹⁾ GEOs, which are provided to assist the reader, are based on the following commodity price assumptions: \$2,600 per ounce gold; \$30.00 per ounce silver; \$950 per ounce palladium; and \$13.50 per pound cobalt; consistent with those used in estimating the Company's production guidance for 2025.

GEO Production

For the three months ended September 30, 2025, attributable GEO production was 173,400 ounces, with the 30,700 ounce increase from the comparable period in 2024 being primarily attributable to the following factors:

9,200 ounce or 86% increase from Antamina (797,000 silver ounces), primarily due to higher throughput and grades, partially offset by lower recoveries;
6,400 ounce increase from Blackwater (comprised of 4,900 gold ounces and 136,000 silver ounces), with the mine achieving commercial production in May 2025;
4,300 ounce or 7% increase from Salobo primarily the result of higher throughput, grades and recoveries. Vale reported on July 22, 2025 that following the implementation of Salobo 3, the Salobo complex has reached full ramp-up and is consistently delivering strong operational performance;
4,000 ounce or 28% increase from the Other mines (comprised of 500 gold ounces and 299,000 silver ounces), primarily due to higher production from Zinkgruvan and the resumption of mining at Aljustrel;
3,500 ounce or 17% increase from Peñasquito (302,000 silver ounces), primarily the result of higher throughput, partially offset by lower grades with mining activities having transitioned back into the Peñasco pit which contains lower silver grades relative to the Chile Colorado pit;
1,400 ounce or 39% increase from Sudbury, primarily due to higher throughput, grades and recoveries;
1,200 ounce or 7% increase from Constancia (comprised of an increase of 2,000 gold ounces and a decrease of 71,000 silver ounces), with the increased gold production being primarily due to higher grades, partially offset by lower throughput;
1,100 ounce or 52% increase from Voisey's Bay (207,000 cobalt pounds) as the underground mine at Voisey's Bay continues ramp-up to full production, with full ramp-up expected by the second half of 2026; and
600 ounce or 9% increase from San Dimas, with higher throughput being partially offset by the change of the gold to silver conversion ratio from 70:1 to 90:1, effective April 30, 2025; partially offset by
1,000 ounce or 28% decrease from Stillwater (comprised of 500 gold ounces and 1,400 palladium ounces), primarily due to lower throughput as Stillwater West operations were placed into care and maintenance in September 2024.

²⁾ GEOs, which are provided to assist the reader, are based on the following commodity price assumptions: \$2,600 per ounce gold; \$30.00 per ounce silver; \$950 per ounce palladium; and \$13.50 per pound cobalt; consistent with those used in estimating the Company's production guidance for 2025.

Net Earnings

For the three months ended September 30, 2025, net earnings amounted to \$367 million, with the \$213 million increase relative to the comparable period of the prior year being attributable to the following factors:

GEO Production

For the nine months ended September 30, 2025, attributable GEO production was 483,500 ounces, with the 37,400 ounce increase from the comparable period in 2024 being primarily attributable to the following factors:

20,300 ounce or 11% increase from Salobo primarily the result of higher throughput, partially offset by lower recoveries.;
16,000 ounce or 51% increase from Antamina (1,385,000 silver ounces), primarily due to higher grades and throughput, partially offset by lower recoveries;
13,500 ounce increase from Blackwater (comprised of 9,900 gold ounces and 308,000 silver ounces), with the mine achieving commercial production in May 2025;
4,600 ounce or 100% increase from Voisey's Bay (895,000 cobalt pounds) as the underground mine at Voisey's Bay continues ramp-up to full production, with full ramp-up expected by the second half of 2026;
2,500 ounce or 5% increase from the Other mines (comprised of 800 gold ounces and 143,000 silver ounces), primarily due to the resumption of mining at Aljustrel;
1,600 ounce or 12% increase from Sudbury, primarily due to higher throughput and recoveries, partially offset by lower grades; and
1,400 ounce or 6% increase from San Dimas, primarily due to higher throughput partially offset by lower grades and recoveries as well as the change of the gold to silver conversion ratio from 70:1 to 90:1, effective April 30, 2025; partially offset by
9,700 ounce or 19% decrease from Constancia (comprised of 9,100 gold ounces and 55,000 silver ounces), primarily due to lower grades as more material was mined from the Constancia pit and reclaimed from the stockpile compared with the prior year;
8,600 ounce or 11% decrease from Peñasquito (749,000 silver ounces), primarily the result of lower grades as mining activities have transitioned back into the Peñasco pit which contains lower silver grades relative to the Chile Colorado pit; and
4,100 ounce or 35% decrease from Stillwater (comprised of 2,300 gold ounces and 5,100 palladium ounces), primarily due to lower throughput as Stillwater West operations were placed into care and maintenance in September 2024.

Net Earnings

For the nine months ended September 30, 2025, net earnings amounted to \$913 million, with the \$472 million increase relative to the comparable period of the prior year being attributable to the following factors:

¹⁾ Equity settled share based compensation is a non-cash expense.

For the three months ended September 30, 2025, share based compensation decreased by \$1 million relative to the comparable period in the previous year with the decrease being primarily due to differences in accrued costs

associated with the Company's performance share units (PSUs), with the increased share price being offset by a reduction to the estimated performance factor at maturity.

To date, the government of the Cayman Islands has indicated that they do not intend to enact Pillar Two Legislation.

Liquidity and Capital Resources1

As at September 30, 2025, the Company had cash and cash equivalents of \$1.2 billion (December 31, 2024 - \$818 million) and no debt outstanding under its Revolving Facility (December 31, 2024 - \$NIL).

In the opinion of management, the \$1.2 billion of cash and cash equivalents as at September 30, 2025, combined with the liquidity provided by the available credit under the \$2 billion Revolving Facility coupled with the \$500 million accordion and ongoing operating cash flows positions the Company well to fund all outstanding commitments, as detailed in the Contractual Obligations and Contingencies section on pages 32 through 36 of this MD&A, as well as providing flexibility to acquire additional accretive mineral stream interests.

¹ Statements made in this section contain forward-looking information with respect to funding outstanding commitments and continuing to acquire accretive mineral stream interests and readers are cautioned that actual outcomes may vary. Please see "Cautionary Note Regarding Forward-Looking Statements" for material risks, assumptions and important disclosure associated with this information.

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

Three Months Ended September 30, 2025

Cash Flows From Operating Activities

During the three months ended September 30, 2025, the Company generated operating cash flows of \$383 million, with the \$129 million increase relative to the comparable period of the prior year being attributable to the following factors:

Operating cash inflow for the three months ended September 30, 2024	\$ 254,337
Changes in:

¹⁾ The cost of sales related to delay ounces is a non-cash expense (see footnote 3 on page 9 of this MD&A for more information).

Working Capital Variance

The decrease to cash inflows relative to working capital was primarily the result of the sale of gold and silver ounces amounting to \$24 million. This sale settled on September 30, 2025, which was a statutory holiday in Canada, and as a result payment was not received until October 1, 2025.

1) The production payment is measured as either a fixed amount per ounce of gold delivered, or as a percentage of the spot price of gold on the date of delivery. Contracts where the payment is a fixed amount per ounce of gold delivered are subject to an annual inflationary increase, with the exception of Sudbury. Additionally, should the prevailing market price for gold be lower than this fixed amount, the per ounce cash payment will be reduced to the prevailing market price, subject to an annual inflationary factor.
2) Subject to an increase to \$550 per ounce of gold after the initial 40-year term.
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. Effective April 30, 2025, the fixed gold to silver exchange ratio was revised from 70:1 to 90:1.
4) To be increased to 22% once the market value of all metals delivered to Wheaton, net of the per ounce cash payment, exceeds the initial upfront cash deposit.
5) Under certain PMPAs, the Company's attributable gold percentage will be reduced once certain thresholds are achieved: a. Blackwater – reduced to 4% once the Company has received 464,000 ounces of gold.
b. Platreef reduced to 50% once the Company has received 218,750 ounces of gold, with a further reduction to 3.125% once the Company has received 428,300 ounces, at which point the per ounce cash payment increases to 80% of the spot price of gold. If certain thresholds are met, including if production through the Platreef project concentrator achieves 5.5 Mtpa, the 3.125% residual gold stream will terminate.
c. Marmato reduced to 5.25% once Wheaton has received 310,000 ounces of gold.
d. Santo Domingo reduced to 67% once the Company has received 285,000 ounces of gold.

k. Kurmuk reduced to 4.8% once the Company has received 220,000 ounces of gold. During any period in which debt exceeding \$150 million ranks ahead of the gold stream, the stream percentage increases to 7.15% and decreases to 5.25% once the drop down threshold is reached.
l. Cotabambas reduced to 16.67% once the Company has received 90 million silver equivalent ounces. 6) On October 21, 2024, the Company amended the Fenix PMPA. Under the original agreement, the Company was to acquire an amount of gold equal to 6% of the gold production until 90,000 ounces have been delivered, 4% of the gold production until the delivery of a further 140,000 ounces and 3.5% gold production thereafter for the life of mine. Under the revised agreement, the Company is entitled to purchase an additional 16% of payable gold production (22% in total) (subject to adjustment if there are delays in deliveries relative to an agreed schedule). Once Rio2 delivers the incremental 95,000 ounces (as adjusted), the stream reverts to the percentages and thresholds under the original Fenix PMPA (as described). Rio2 has a one-time option to terminate the requirement to deliver the incremental gold production from the end of 2027 until the end of 2029 by delivering 95,000 ounces (as adjusted) less previously delivered gold ounces, excluding those gold ounces which would have been delivered under the original Fenix PMPA.

7) Under the Kudz Ze Kayah PMPA, the Company will be entitled to purchase staged percentages of produced gold ranging from 6.875% to 7.375% until 330,000 ounces of gold are produced and delivered, thereafter reducing to a range of 5.625% to 6.125% until a further 59,800 ounces of gold are produced and delivered, further reducing to a range of 5% to 5.5% until a further 270,200 ounces of gold are produced and delivered for a total of 660,000 ounces of gold thereafter ranging between 6.25% and 6.75%.
8) On February 27, 2024, the Company closed the Orion Purchase Agreement to acquire the Platreef and Kudz Ze Kayah PMPAs.
9) Until October 23, 2029, there is a price adjustment mechanism under the Koné PMPA:
a. if the spot price of gold is less than \$2,100 per ounce, the Company will pay 20% of \$2,100 less 25% of the difference between \$2,100 and \$1,800, less 30% of the difference between \$1,800 and the spot price of gold; and
b. if the spot price is greater than \$2,700 per ounce, the Company will pay 25% of the difference between \$3,000 and \$2,700, plus 30% of the difference between the actual spot price of gold and \$3,000.

Kutcho

Under the terms of the Kutcho Early Deposit Agreement, the Company is committed to pay Kutcho additional upfront cash payments of \$58 million, which will be advanced on an installment basis to partially fund construction of the mine once certain conditions have been satisfied.

Tax Contingencies

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

Under the terms of the settlement with the CRA of the transfer pricing dispute relating to the 2005 to 2010 taxation years (the "CRA Settlement"), income earned outside of Canada by the Company's foreign subsidiaries will not be subject to tax in Canada under transfer pricing rules. The CRA Settlement principles apply to all taxation years after 2010 subject to there being no material change in facts or change in law or jurisprudence. The CRA is not restricted under the terms of the CRA Settlement from issuing reassessments on some basis other than transfer pricing which could result in some or all of the income of the Company's foreign subsidiaries being subject to tax in Canada.

It is not known or determinable by the Company when any ongoing audits by CRA of international and domestic transactions will be completed, or whether reassessments will be issued, or the basis, quantum or timing of any such potential reassessments, and it is therefore not practicable for the Company to estimate the financial effect, if any, of any ongoing audits.

From time to time there may also be proposed legislative changes to law or outstanding legal actions that may have an impact on the current or prior periods, the outcome, applicability and impact of which is also not known or determinable by the Company.

General

By their nature, contingencies will only be resolved when one or more future events occur or fail to occur. The assessment of contingencies inherently involves the exercise of significant judgment and estimates of the outcome of future events. If the Company is unable to resolve any of these matters favorably, there may be a material adverse impact on the Company's financial performance, cash flows or results of operations. In the event that the Company's estimate of the future resolution of any of the foregoing matters changes, the Company will recognize the effects of the change in its consolidated financial statements in the appropriate period relative to when such change occurs.

Share Capital

During the three months ended September 30, 2025, a total of 49,118 share purchase options were exercised at a weighted average exercise price of Cdn\$57.64 per option, resulting in total cash proceeds to the Company in the amount of \$2 million (nine months - \$6 million from the exercise of 161,388 share purchase options at a weighted average exercise price of Cdn\$56.03). During the three months ended September 30, 2024, the Company received proceeds of \$1 million from the exercise of 25,098 share purchase options at a weighted average exercise price of Cdn\$47.17 per option (nine months - \$13 million from the exercise of 494,457 share purchase options at a weighted average exercise price of Cdn\$36.17).

During the nine months ended September 30, 2025, the Company released 141,525 RSUs, with all releases taking place during the six months ended June 30, 2025. During the nine months ended September 30, 2024, the Company released 69,494 RSUs, with all releases taking place during the six months ended June 30, 2024.

The Company has implemented a dividend reinvestment plan ("DRIP") whereby shareholders can elect to have dividends reinvested directly into additional Wheaton common shares. During the three months ended September 30, 2025, there were 6,706 common shares issued under the DRIP (nine months - 29,914 common shares). During the three months ended September 30, 2024, there were 5,379 common shares issued under the DRIP (nine months - 32,518 common shares).

As of November 6, 2025, there were 454,017,886 outstanding common shares, 1,050,649 share purchase options and 241,880 restricted share units.

Financial Instruments

The Company owns equity interests in several companies as long-term investments (see page 13 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 gold, silver and palladium prices, the Company will occasionally enter into forward contracts in relation to gold, silver and palladium deliveries that it is highly confident will occur within a given quarter. The Company does not hedge its long-term exposure to commodity prices. 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.

New Accounting Standards Effective in 2025

Amendment to IAS 21 - Lack of Exchangeability

Effective January 1, 2025, the Company adopted the Amendment to IAS 21 - Lack of Exchangeability. The amendments contain guidance to specify when a currency is exchangeable and how to determine the exchange rate when it is not, as well as associated disclosure requirements when it is concluded a currency is not exchangeable. The adoption of this amendment had no impact on the condensed interim consolidated financial statements.

Non-GAAP Measures

Wheaton has included, throughout this document, certain non-GAAP 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 gold, silver and palladium on a per ounce basis and cobalt on a per pound basis; and (iv) cash operating margin.

These non-GAAP measures do not have any standardized meaning prescribed by IFRS Accounting Standards as issued by the International Accounting Standards Board ("IFRS Accounting Standards"), and other companies may calculate these measures differently. The presentation of these non-GAAP 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 Accounting Standards.

i. Adjusted net earnings and adjusted net earnings per share are calculated by removing the effects of noncash impairment charges (reversals) (if any), non-cash fair value (gains) losses and other one-time (income) expenses as well as the reversal of non-cash income tax expense (recovery) which is offset by income tax expense (recovery) recognized in the Statements of Shareholders' Equity and OCI, respectively. The Company believes that, in addition to conventional measures prepared in accordance with IFRS Accounting Standards, 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 September 30				Nine Months Ended September 30

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).

Operating cash flow per share - diluted	\$	0.842	\$	0.560	\$	2.549	\$	1.560

iii. Average cash cost of gold, silver and palladium on a per ounce basis and cobalt on a per pound basis is calculated by dividing the total cost of sales, less depletion and cost of sales related to delay ounces, by the ounces or pounds sold. In the precious metal mining industry, this is a common performance measure but does not have any standardized meaning prescribed by IFRS Accounting Standards. In addition to conventional measures prepared in accordance with IFRS Accounting Standards, 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 gold, silver and palladium on a per ounce basis and cobalt on a per pound basis.

¹⁾ The cost of sales related to delay ounces is a non-cash expense (see footnote 3 on page 9 of this MD&A for more information).

iv. Cash operating margin is calculated by adding back depletion and the cost of sales related to delay ounces to the gross margin. Cash operating margin on a per ounce or per pound basis is calculated by dividing the cash operating margin by the number of ounces or pounds sold during the period. 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

Under the Company's dividend policy, the quarterly dividend is fixed at \$0.165 per common share for 2025. The declaration, timing, amount and payment of future dividends remain at the discretion of the Board of Directors.

On November 6, 2025, the Board of Directors declared a dividend in the amount of \$0.165 per common share, with this dividend being payable to shareholders of record on November 20, 2025 and is expected to be distributed on or about December 4, 2025. The Company has implemented a dividend reinvestment plan ("DRIP") whereby shareholders can elect to have dividends reinvested directly into additional Wheaton common shares based on the Average Market Price, as defined in the DRIP.

Acquisition of Spring Valley PMPA

On November 6, 2025, the Company entered into a PMPA (the "Spring Valley PMPA") with Waterton Gold Corp., a subsidiary of Waterton Gold LP ("Waterton Gold") in respect of its Spring Valley project located in Nevada, USA. Under the Spring Valley PMPA, the Company will purchase an amount of gold equal to 8% of the payable gold until 300,000 ounces have been delivered, after which the Company will purchase 6% of the payable gold for the life of the mine. Under the terms of the Spring Valley PMPA, the Company is committed to pay Waterton Gold total upfront cash payments of \$670 million, to be paid in installments as various conditions are satisfied. In addition, Wheaton will make ongoing payments for the gold ounces delivered equal to 20% of the spot price of gold until the value of the gold delivered, net of the production payment, is equal to the upfront consideration of \$670 million, at which point the production payment will increase to 22% of the spot price of gold. The Company also entered into a cost overrun facility (the "Facility") of up to \$150 million, accessible during an availability period commencing once the full upfront consideration has been paid under the Spring Valley PMPA. The Facility has a maturity date of three years following the first drawdown under the Facility.

Controls and Procedures

Disclosure Controls and Procedures

Management is responsible for establishing and maintaining adequate internal control over financial reporting and disclosure controls and procedures, as those terms are defined in National Instrument 52-109 – Certification of Disclosure in Issuers' Annual and Interim Filings, for the Company.

Together, the internal control frameworks provide internal control over financial reporting and disclosure. Due to its inherent limitations, internal control over financial reporting and disclosure may not prevent or detect all misstatements. Further, the effectiveness of internal control is subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies or procedures may change.

There were no changes in the Company's internal controls over financial reporting during the three months ended September 30, 2025 that have materially affected, or are reasonably likely to materially affect, the internal controls over financial reporting.

Under the supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer, management will continue to monitor and evaluate the design and effectiveness of its internal control over financial reporting and disclosure controls and procedures, and may make modifications from time to time as considered necessary.

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.

Attributable Reserves and Resources The following tables set forth the estimated Mineral Reserves and Mineral Resources (metals attributable to Wheaton only) for the mines relating to which the Company has PMPAs, adjusted where applicable to reflect the Company's percentage entitlement to such metals, as of December 31, 2024, unless otherwise noted.

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, 2024 and other continuous disclosure documents filed by Wheaton since January 1, 2025, available on SEDAR+ at www.sedarplus.ca. 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 Definition Standards"). NI 43-101 differs significantly from the disclosure requirements of the SEC generally applicable to U.S. companies. For example, there is no assurance any mineral reserves or mineral resources that the Company may report as "proven mineral reserves", "probable mineral reserves", "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under NI 43-101 would be the same had the Company prepared the reserve or resource estimates under the standards of the SEC generally applicable to U.S. companies. 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.html.
