Operational Overview

Financial Review

Revenues
Revenue in the fourth quarter of 2023 was $313 million (74% gold, 24% silver, 1% palladium and 1% cobalt), with the $77 million increase relative to the prior period quarter being primarily due to a 17% increase in the number of GEOs³ sold; and a 13% increase in the average realized gold equivalent³ price.

Revenue was $1,016 million in the year ended December 31, 2023, representing a $49 million decrease from 2022 due primarily to a 10% decrease in the number of GEOs³ sold, resulting from relative changes in the GEOs³ produced but not yet delivered; partially offset by a 6% increase in the average realized gold equivalent³ price.

Cash Costs and Margin
Average cash costs¹ in the fourth quarter of 2023 were $417 per GEO³ as compared to $447 in the fourth quarter of 2022. This resulted in a cash operating margin¹ of $1,514 per GEO³ sold, an increase of 20% as compared with the fourth quarter of 2022, a result of the higher realized price per ounce coupled with the lower average cash costs.

Average cash costs¹ in 2023 were $424 per GEO³ as compared to $447 in 2022. This resulted in a cash operating margin¹ of $1,466 per GEO³ sold, a 10% increase from 2022.

Cash Flow from Operations
Operating cash flow in the fourth quarter of 2023 amounted to $242 million, with the $70 million increase due primarily to the higher gross margin.

Operating cash flows in 2023 amounted to $751 million, with the $7 million increase from the comparable period of the previous year being due primarily to higher amounts of interest received during the current year, partially offset by lower sales volumes.

Balance Sheet (at December 31, 2023)

• Approximately $547 million of cash on hand
• During the fourth quarter of 2023, the Company made total upfront cash payments of $452 million relative to the mineral stream interests consisting of
  • $35 million payment relative to the Blackwater Silver precious metals purchase agreement ("PMPA");
  • a $10 million payment relative to the expansion of the Blackwater Gold PMPA;
  • $17 million relative to the Cangrejos PMPA;
  • $20 million relative to the Curraghinalt PMPA; and
  • $370 million relative to the Salobo III expansion payment
• With the existing cash on hand coupled with the fully undrawn $2 billion revolving credit facility, the Company believes it is well positioned to fund all outstanding commitments and known contingencies as well as providing flexibility to acquire additional accretive mineral stream interests.

Fourth Quarter Operating Asset Highlights

Salobo: In the fourth quarter of 2023, Salobo produced 71,800 ounces of attributable gold, an increase of approximately 89% relative to the fourth quarter of 2022, driven by higher throughput, with production from the third concentrator line commencing at the end of 2022, combined with higher grades and recoveries. The prior year was also impacted by changes in maintenance routines. In the fourth quarter of 2023, Salobo reached its highest production level since the fourth quarter of 2019 as the ramp-up of the Salobo III expansion continued to advance.

On November 21, 2023, Vale reported the successful completion of the throughput test for the first phase of the Salobo III project, with the Salobo complex exceeding an average of 32 Mtpa over a 90-day period. Under the terms of the agreement, the Company paid Salobo $370 million for the completion of the first phase of the Salobo III expansion project on December 1, 2023. Salobo III is expected to achieve a sustained throughput capacity of 36 Mtpa in the fourth quarter of 2024.

Antamina:In the fourth quarter of 2023, Antamina produced 1.0 million ounces of attributable silver, a decrease of approximately 3% relative to the fourth quarter of 2022. On February 15, 2024, Peru's National Environmental Certification Service for Sustainable Investments approved, after a detailed evaluation process, the Modification of the Environmental Impact Study, which will allow for the extension of Antamina's mine life from 2028 to 2036.

Peñasquito:In the fourth quarter of 2023, Peñasquito produced 1.0 million ounces of attributable silver, a decrease of approximately 41% relative to the fourth quarter of 2022 primarily due to lower throughput resulting from a labour strike which began on June 7, 2023 and ended on October 13, 2023. Newmont Corporation ("Newmont") reports that operations have since safely ramped up after a resolution was reached with the National Union of Mine and Metal Workers of the Mexican Republic ("the Union") on October 13, 2023. Newmont has indicated that Peñasquito is expected to deliver higher co-product production in 2024 due to higher silver, lead and zinc content from the Chile Colorado pit.

Constancia:In the fourth quarter of 2023, Constancia produced 0.8 million ounces of attributable silver and 22,300 ounces of attributable gold, an increase of approximately 28% and 112%, respectively, relative to the fourth quarter of 2022. Record quarterly gold production combined with strong silver production are a result of significantly higher grades attributable to the mining of high-grade zones of the Pampacancha deposit, combined with higher recoveries. Hudbay Minerals Inc. ("Hudbay") reports that gold production in 2024 is expected to decrease from 2023 levels due to a smoothing of Pampacancha high-grade gold zones over the 2023 to 2025 period as additional high-grade areas were mined in 2023 ahead of schedule, and other high-grade areas were deferred to 2025. Hudbay has indicated that the Pampacancha deposit is now expected to be depleted in the third quarter of 2025, as opposed to mid-2025 as previously reported.

Sudbury:In the fourth quarter of 2023, Vale's Sudbury mines produced 6,300 ounces of attributable gold, an increase of approximately 19% relative to the fourth quarter of 2022, due to higher throughput, grade and recoveries.

Stillwater: In the fourth quarter of 2023, the Stillwater mines produced 2,300 ounces of attributable gold and 4,200 ounces of attributable palladium, an increase of approximately 7% for gold and 9% for palladium relative to the fourth quarter of 2022, due primarily to higher throughput and grades.

Voisey's Bay: In the fourth quarter of 2023, the Voisey's Bay mine produced 215,000 pounds of attributable cobalt, an increase of approximately 67% relative to the fourth quarter of 2022, as the transitional period between the depletion of the Ovoid open-pit and ramp-up to full production of the Voisey's Bay underground extension nears completion. Vale reports that physical completion of the Voisey's Bay underground mine extension was 92% at the end of the fourth quarter, and that the main surface assets are completed and already operating. The electromechanical assembly on the remaining surface assets are well advanced (above 60% physical progress). In the underground portion, the scope in Reid Brook is completed and the project is fully focused on Eastern Deeps. The mine development is concluded and construction is ongoing.

Other Gold:In the fourth quarter of 2023, total Other Gold attributable production was 700 ounces, a decrease of approximately 78% relative to the fourth quarter of 2022, primarily due to the closure of the Minto mine in May 2023.

Other Silver: In the fourth quarter of 2023, total Other Silver attributable production was 1.3 million ounces, a decrease of approximately 28% relative to the fourth quarter of 2022, primarily due to the temporary suspension of attributable production from Aljustrel and the disposal of the Yauliyacu PMPA.

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.

Declaration of Dividend and Transition to Progressive Dividend Policy

The Company has revised its dividend policy, transitioning from distributing 30% of the average of the previous four quarters' operating cash flows to shareholders, to adopting a progressive dividend policy marked by an increase in our 2024 annual dividend. The declaration, timing, amount and payment of future dividends remain at the discretion of the Board of Directors.

On March 14, 2024, the Board of Directors declared a dividend in the amount of $0.155 per common share, with this dividend being payable to shareholders of record on April 3, 2024 and is expected to be distributed on or about April 15, 2024. 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.

2024 and Long-Term Production Outlook Using Updated 2024 Commodity Price Assumptions

It is important to note that as gold outperformed all other metals during 2023, the assumed metal prices for 2024 results in lower gold equivalency calculations1 in 2024 compared to 2023.

In 2024, GEO5 production is forecast to be consistent with levels achieved in 2023, as expected stronger attributable production from Peñasquito and Voisey's Bay is forecast to be offset by lower production from Salobo, the suspension of operations at Minto, and the temporary halting of production at Aljustrel. Attributable production is forecast to increase at Peñasquito as a result of uninterrupted operations, and at Voisey's Bay due to the ongoing transition from the Ovoid pit to the underground mines. Attributable production is forecast to decrease slightly at Salobo due to lower grades as per the mine plan, which are expected to partially offset increasing throughput as the Salobo III expansion project continues toward completion. In addition, the Company anticipates production from the Blackwater project to commence in the fourth quarter of 2024.

On May 13, 2023, it was announced that operations at the Minto Mine had been suspended, and the Yukon Government had assumed care and control of the site. On September 12, 2023, it was announced that as a result of low zinc prices, the production of zinc and lead concentrates at the Aljustrel Mine would be halted from September 24, 2023, until the second quarter of 2025. Combined, the removal of production from Minto and Aljustrel accounts for a 25,000 GEO5 reduction in 2024 production guidance.

Long-Term Production Outlook

Historically, Wheaton has provided 5 and 10-year averages for its long-term guidance, however, the Company has elected to introduce a 5-year target (2028), in addition to an annual average for years 6 through 10 (i.e. 2029-2033), with a goal of providing increased granularity and further transparency of our expected growth trajectory.

Production is forecast to increase by approximately 40% over the next five years to over 800,000 GEOs5 by 2028, primarily due to growth from Operating assets including Salobo, Antamina, Peñasquito, Voisey's Bay and Marmato; Development projects which are in-construction and/or permitted including Blackwater, Platreef, Goose, Mineral Park, Fenix, Curipamba and Santo Domingo; and Pre-development projects including Marathon and Copper World, for which production is anticipated towards the latter end of the five-year forecast period.

From 2029 to 2033, attributable production is forecast to average over 850,000 GEOs5 in the five-year period and incorporates additional incremental production from pre-development assets including Cangrejos, Kudz ze Kayah, Curraghinalt, Victor and Kutcho projects, in addition to the Brewery Creek, Black Pine and Mt. Todd royalties.

Not included in Wheaton's long-term forecast and instead classified as 'optionality', includes potential future production from Pascua Lama, Navidad, Toroparu, Cotabambas, Metates, DeLamar and additional expansions at Salobo outside of the Salobo III mine expansion project.

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.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 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.
