FIRST QUARTER FINANCIAL RESULTS

Wheaton Precious Metals Announces Solid Start to 2023

“Wheaton’s high-quality portfolio of long-life, low-cost assets delivered a solid performance to start the year, resulting in revenue of $214 million and robust cash operating margins,” said Randy Smallwood, President and Chief Executive Officer of Wheaton Precious Metals. “First quarter production was ahead of Company expectations, and as we continue to see positive developments at a number of our key assets including Salobo and Constancia, we expect to see significant production growth throughout 2023, culminating in a strong second half of the year. Notably, implicit in our five-year annual average production guidance, is an impressive organic growth profile of over 40%, with two-thirds coming from assets already in operation. In addition, our corporate development team remains exceptionally busy evaluating new opportunities, and as always, Wheaton is focused on ensuring our growth is both accretive and sustainable for all of our stakeholders."

Financial Review

Revenues

Revenue was $214 million (56% gold, 40% silver, 2% palladium and 2% cobalt), with the $93 million decrease being primarily due to the cessation of production from Yauliyacu, 777 and Keno Hill coupled with relative changes in the GEOs produced but not yet delivered³ and a 5% decrease in the average realized gold equivalent³ price.

Cash Costs and Margin

Average cash costs¹ in the first quarter of 2023 were $443 per GEO² as compared to $440 in the first quarter of 2022. This resulted in a cash operating margin¹ of $1,384 per GEO³ sold, a decrease of 7% as compared with the first quarter of 2022.

Cash Flow from Operations

Operating cashflow amounted to $135 million, with the $75 million decrease being due primarily to the lower cash operating margin and the payout of the Company’s performance share units in the first quarter of 2023 while in 2022 they were paid in the second quarter.

Balance Sheet (at March 31, 2023)

•

Approximately $800 million of cash on hand

•

During the first quarter of 2023, the Company made an upfront cash payment of $31 million relative to the Goose PMPA

•

With the existing cash on hand coupled with the fully undrawn $2 billion revolving credit facility, the Company is well positioned to fund all outstanding commitments and known contingencies as well as providing flexibility to acquire additional accretive mineral stream interests

First Quarter Operating Asset Highlights

Salobo: In the first quarter of 2023, Salobo produced 43,700 ounces of attributable gold, virtually unchanged relative to the first quarter of 2022, with higher grades and throughput offset by lower recovery. According to Vale S.A. (“Vale”), production in the first quarter was impacted by planned and corrective maintenance activities, with additional maintenance planned for the second quarter.

Vale reports that the Salobo III mine expansion project, which will increase the mill throughput by 50%, successfully commenced at the end of 2022. The project consists of two lines, both of which are already in operation, and is expected to reach full capacity in the fourth quarter of 2024.

Antamina: In the first quarter of 2023, Antamina produced 0.9 million ounces of attributable silver, a decrease of approximately 31% relative to the first quarter of 2022, primarily due to lower grades as per the mine plan.

Peñasquito: In the first quarter of 2023, Peñasquito produced 2.1 million ounces of attributable silver, a decrease of approximately 6% relative to the first quarter of 2022 due to lower recoveries partially offset by higher grades.

Constancia: In the first quarter of 2023, Constancia produced 0.6 million ounces of attributable silver and 6,900 ounces of attributable gold, an increase of approximately 9% for both metals relative to the first quarter of 2022, with the increase in both metals being primarily due to higher throughput and grades. As per Hudbay, full mining activities resumed in the Pampacancha pit in February and the period of higher stripping from March to June is progressing well, with mining of higher-grade ore now expected in the second quarter of 2023, ahead of schedule.

Sudbury: In the first quarter of 2023, Vale’s Sudbury mines produced 6,200 ounces of attributable gold, an increase of approximately 16% relative to the first quarter of 2022. As per Vale, higher production from Sudbury was driven by greater mine performance and stability in the first quarter.

Stillwater: In the first quarter of 2023, the Stillwater mines produced 2,000 ounces of attributable gold and 3,700 ounces of attributable palladium, a decrease of approximately 21% for gold and 17% for palladium relative to the first quarter of 2022. As reported by Sibanye-Stillwater Limited (“Sibanye”) on March 13, 2023, an incident occurred at the Stillwater mine during scheduled non-routine maintenance resulting in structural damage to the shaft headgear, winder house and winder rope. As a result, production from the Stillwater West mine below the 50 level was suspended for approximately five weeks, impacting production in the first quarter, but has since recommenced. Sibanye continues to reposition the Stillwater operations for the current skills shortage and changing macro environment and expects further normalization of production rates in 2023.

San Dimas: In the first quarter of 2023, San Dimas produced 10,800 ounces of attributable gold, virtually unchanged relative to the first quarter of 2022.

Other Gold: In the first quarter of 2023, total Other Gold attributable production was 3,500 ounces, a decrease of approximately 59% relative to the first quarter of 2022, primarily due to the closure of the 777 mine in June 2022.

-4-

Other Silver: In the first quarter of 2023, total Other Silver attributable production was 1.4 million ounces, a decrease of approximately 36% relative to the first quarter of 2022, primarily due to the closure of the 777 mine and the termination of the Keno Hill and Yauliyacu PMPAs.

Voisey’s Bay: In the first quarter of 2023, the Voisey's Bay mine produced 124,000 pounds of attributable cobalt, a decrease of approximately 47% relative to the first quarter of 2022, primarily due to mining lower grade material during the ongoing transitional period between the depletion of the Ovoid open-pit mine and ramp-up to full production of the Voisey’s Bay underground project. Vale reports that planned maintenance activities are scheduled for the second quarter of 2023. Vale reports that physical completion of the Voisey’s Bay underground mine extension was 83% at the end of the first quarter. In the second quarter of 2021, Vale achieved the first ore production from the Reid Brook deposit, the first of two underground mines to be developed in the project. Eastern Deeps, the second deposit, has started to extract development ore from the deposit and is scheduled to start the main production ramp-up in the second half of 2023.

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.

First Quarter Development Asset Highlights

Blackwater Project: Artemis Gold Inc. (“Artemis”) announced the approval of its BC Mines Act Permit, the final step required to allow Artemis to commence major works construction activities at the Blackwater Mine, with the expectation of an initial gold pour in the second half of 2024. In addition, Artemis announced that it issued a purchase order to Finning Canada, for the primary and ancillary mining fleet required for the initial Phase 1 of operations. Equipment deliveries to site are planned to commence late in the fourth quarter of 2023 and continue throughout the first half of 2024, in preparation for the pre-strip-mining phase. As per Artemis, the entire fleet is expected to be “shovel ready” during the second half of 2024, to meet Artemis’ operational readiness objectives and commence operations.

Copper World Complex: In January 2023, Hudbay received an approved right-of-way from the Arizona State Land Department that will allow for infrastructure such as roads, pipelines and powerlines, to connect between the properties in the company’s private land package at Copper World. Subsequent to the quarter, Hudbay announced the receipt of confirmation from the Army Corps of Engineers that Hudbay’s previous surrender of the Section 404 Clean Water Act permit for the former Rosemont project was formally accepted and revoked as requested. Clearing and grading work to prepare for the Copper World site, including the construction of roads and other facilities, continues to be underway. As per Hudbay, pre-feasibility activities for the private land Phase I of the Copper World project are well-advanced and a pre-feasibility study is expected to be released in mid-2023.

Goose Project: On April 12, 2023, Sabina Gold & Silver Corp (“Sabina”) announced that the shareholders approved the proposed acquisition by B2Gold Corp. (“B2Gold”) of all the issued and outstanding common shares of Sabina. The transaction closed April 19, 2023. Subsequent to closing, B2Gold exercised the option to acquire 33% of the stream under the Goose PMPA in exchange for a cash payment in the amount of $46 million, resulting in a gain on partial disposal of the PMPA in the amount of $5 million. B2Gold continues to advance construction of the Goose project, moving toward commencement of production in 2025 and initiating an exploration program to further define untapped potential and unlock further opportunities for growth.

Marathon Project: Generation Mining Limited (“Gen Mining”) announced positive results on the updated Feasibility Study for the Marathon Project, presenting an optimized design with increased process plant throughput. Additionally, Gen Mining finalized an offtake term sheet with Glencore for copper concentrate, containing copper, palladium, platinum, gold, and silver. Finally, Gen Mining has executed a mandate letter to arrange a senior secured project finance facility of up to $400 million, with a syndicate including Export Development Canada, together with ING Capital LLC and Societe Generale S.A. acting as the Mandated Lead Arrangers. This represents a key milestone in the project financing process for the development of the Marathon Project.

Sustainability

Climate Change:

•

Subsequent to the quarter, on April 27, 2023, Hudbay announced the signing of a new 10-year power purchase agreement with ENGIE Energía Perú for access to a 100% renewable energy supply to Hudbay’s Constancia operations in Peru. As reported by Hudbay, Hudbay’s Scope 1 and Scope 2 greenhouse gas emissions are expected to significantly decline as a result of the new Constancia renewable energy supply agreement, which should reduce Wheaton’s attributable scope 3 emissions from the Constancia mine and help advance the Company’s Net Zero targets.

Community Investment Program:

•

The Daffodil Ball presented by Wheaton raised a record of over CA$3 million for the Canadian Cancer Society.

•

The Pacific Salmon Foundation’s Vancouver Gala presented by Wheaton raised CA$530,000 in support of advancing critical marine science research and conservation work.

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

Quantity produced represents 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 and Totten gold interests. Operations at the Sudbury mines were suspended from June 1, 2021 to August 9, 2021 as a result of a labour disruption by unionized employees.

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. For reference, attributable silver production from prior periods is as follows: Q1 2023 - 401,000 ounces; Q4 2022 - 348,000 ounces; Q3 2022 - 412,000 ounces; Q2 2022 - 382,000 ounces; Q1 2022 - 408,000 ounces; Q4 2021 - 544,000 ounces; Q3 2021 - 472,000 ounces; Q2 2021 - 467,000 ounces.

5)	Comprised of the Stillwater and East Boulder gold and palladium interests.

6)	On June 22, 2022, Hudbay announced that mining activities at 777 have concluded and closure activities have commenced.

7)	Operations at Los Filos were temporarily suspended from June 22, 2021 to July 26, 2021 as the result of illegal blockades by a group of unionized employees and members of the Xochipala community.

8)	On December 14, 2022 the Company terminated the Yauliyacu PMPA in exchange for a cash payment of $132 million.

9)	The Stratoni mine was placed into care and maintenance during Q4-2021.

10)	On September 7, 2022, the Company terminated the Keno Hill PMPA in exchange for $141 million of Hecla common stock.

11)	GEOs, which are provided to assist the reader, are based on the following commodity price assumptions: $1,850 per ounce gold; $24.00 per ounce silver; $1,800 per ounce palladium; and $18.75 per pound cobalt; consistent with those used in estimating the Company's production guidance for 2023.

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 gold, silver and palladium on a per ounce basis and cobalt on a per pound basis; and (iv) cash operating margin.

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, 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).

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, 2022, which was filed on March 31, 2023 and other continuous disclosure documents filed by Wheaton since January 1, 2023, 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 Company reports information regarding mineral properties, mineralization and estimates of mineral reserves and mineral resources in accordance with Canadian reporting requirements which are governed by, and utilize definitions required by, 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 adopted by the United States Securities and Exchange Commission (“SEC”) under the United States Securities Act of 1933, as amended (the “Securities Act”) which are applicable to U.S. companies. Accordingly, 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 adopted by the SEC. 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 https://www.sec.gov/edgar.shtml.
