THIRD QUARTER FINANCIAL RESULTS

Wheaton Precious Metals Announces Record Revenue, Earnings and Cash

Flow for the First Nine Months of 2025

“Our portfolio of high-quality assets continued to deliver strong results, generating record revenue, earnings, and cash flow for the first nine months of 2025,” said Randy Smallwood, Chief Executive Officer of Wheaton Precious Metals. “We advanced our near-term growth strategy through key milestones including the ramp up of production at Blackwater and Goose, alongside continued construction across six development projects scheduled to come online over the next 24 months. These strong results position us well to meet our annual production guidance of 600,000 to 670,000 gold equivalent ounces and underscores the streaming model’s ability to generate predictable levered cash flows in a rising precious metals price environment.”

“This robust quarter also included the announcement of a gold stream on the Hemlo Mine, a transaction that reflects Wheaton’s ongoing commitment to investing in assets with strong geological potential, responsible stewardship, and long-term value creation capacity,” added Haytham Hodaly, President of Wheaton Precious Metals. “The strength of our Q3 results underscore our disciplined approach to capital deployment, prioritizing accretive opportunities that are structured with the goal of delivering meaningful, lasting value for all stakeholders.”

Financial Review

Revenues

Revenue in the third quarter of 2025 was $476 million (58% gold, 39% silver, 1% palladium and 2% cobalt), with the $168 million increase relative to the prior period quarter being primarily due to a 37% increase in the average realized gold equivalent³ price; and a 13% increase in the number of GEOs³ sold.

Revenue was $1.4 billion in the nine months ended September 30, 2025, representing a $546 million increase from the comparable period of the previous year due primarily to a 35% increase in the average realized gold equivalent³ price; and a 19% increase in the number of GEOs³ sold.

Cash Costs and Margin

Average cash costs¹ in the third quarter of 2025 were $532 per GEO³ as compared to $439 in the third quarter of 2024. This resulted in a cash operating margin¹ of $2,930 per GEO³ sold, an increase of 41% as compared with the third quarter of 2024, a result of the higher realized price per ounce. The higher margin reflects the leverage provided by fixed per-ounce production payments across the majority of Wheaton’s operating streams, which accounted for 76% of revenue during the quarter. Notably, year-over-year margin growth exceeded the appreciation in gold prices over the same period, underscoring the effectiveness of Wheaton’s business model in generating higher levered cash flow and margins in a rising precious metals price environment.

Average cash costs¹ for the nine months ended September 30, 2025 were $480 per GEO³ as compared to $436 in the comparable period of the previous year. This resulted in a cash operating margin¹ of $2,667 per GEO³ sold, a 41% increase from comparable period of the previous year, a result of the higher realized price per ounce.

Cash Flow from Operations

Operating cash flow in the third quarter of 2025 amounted to $383 million, with the $129 million increase from the comparable period of the prior year being due primarily to higher gross margin.

Operating cash flows for the nine months ended September 30, 2025 amounted to $1.2 billion, with the $451 million increase from the comparable period of the previous year being due primarily to higher gross margin.

Produced But Not Yet Delivered

As at September 30, 2025, approximately 151,800 GEOs were produced but not yet delivered (“PBND”). PBND increased by 21,000 GEOs during the quarter and represents approximately 2.9 months of payable production, compared to 2.7 months in the previous quarter, reflecting normal variations in shipment timing and delivery cycles. The Company expects PBND levels to stay at the higher end of our forecasted range of two to three months until the end of 2025, in part due to the ramp up of new mines, forecast to commence operations in the fourth quarter.

Third Quarter Operating Asset Highlights

Salobo: In the third quarter of 2025, Salobo produced 67,000 ounces of attributable gold, an increase of approximately 7% relative to the third quarter of 2024, 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.

Antamina: In the third quarter of 2025, Antamina produced 1.7 million ounces of attributable silver, an increase of approximately 86% relative to the third quarter of 2024, primarily due to higher throughput and grades, partially offset by lower recoveries.

Pe ñ asquito: In the third quarter of 2025, Peñasquito produced 2.1 million ounces of attributable silver, an increase of approximately 17% relative to the third quarter of 2024, 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.

Constancia: In the third quarter of 2025, Constancia produced 0.6 million ounces of attributable silver and 12,800 ounces of attributable gold, a decrease of approximately 11% for silver production and an increase of approximately 19% for gold production relative to the third quarter of 2024. The decrease in silver was primarily the result of lower grades, throughput and recoveries. On September 23, 2025, Hudbay Minerals Inc. (“Hudbay”) commented on ongoing social unrest in Peru, where Hudbay’s Constancia mine has been impacted by local protests and illegal blockades. Hudbay announced that the mill was temporarily shut down as a safety precaution and to allow time for authorities to address the illegal protests. Subsequently on October 7, 2025, Hudbay announced it had resumed operations at the Constancia mine following the temporary shutdown.

San Dimas: In the third quarter of 2025, San Dimas produced 7,500 ounces of attributable gold, an increase of approximately 9% relative to the third quarter of 2024, 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.

Stillwater: In the third quarter of 2025, the Stillwater mines produced 1,700 ounces of attributable gold and 2,700 ounces of attributable palladium, a decrease of approximately 24% for gold and 34% for palladium relative to the third quarter of 2024, primarily due to lower

- 5 -

throughput as Stillwater West operations were placed into care and maintenance in September 2024.

As reported by B2Gold, open pit and underground mining rates at the Umwelt deposit have continued to meet or exceed expectations during the 30-day commercial production period. Gold recoveries have been in line with expectations and are expected to average higher than 90% through Q4 2025.

Voisey’s Bay: In the third quarter of 2025, the Voisey’s Bay mine produced 604,000 pounds of attributable cobalt, an increase of approximately 52% relative to the third quarter of 2024 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.

Other Gold: In the third quarter of 2025, total Other Gold attributable production was 1,200 ounces, an increase of approximately 84% relative to the third quarter of 2024 due to the initial reported production from the Goose mine, which achieved commercial production on October 6, 2025. Notable operational updates for assets included within ‘other gold’ include:

| ● |  | Marmato: On October 29, 2025, Aris Mining Corporation (“Aris”) reported that the expansion construction of the Bulk Mining Zone at the Marmato mine is underway and production remains on schedule for first gold in the second half of 2026.

Other Silver: In the third quarter of 2025, total Other Silver attributable production was 1.5 million ounces, an increase of approximately 25% relative to the third quarter of 2024, primarily due to higher production at Zinkgruvan. Notable operational updates for assets included within ‘other silver’ include:

| ● |  | Aljustrel: In the third quarter of 2025, Almina resumed production of the zinc and lead concentrates at the Aljustrel mine, resulting in the resumption of attributable silver production to the Company.

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

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.

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

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.

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.

7) | On April 1, 2025, Equinox Gold Corp., 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.

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.

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.

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.

| i. | Adjusted net earnings and adjusted net earnings per share are calculated by removing the effects of non-cash 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).
