Financial Review

Revenues
Revenue in the first quarter of 2026 was $901 million (51% gold, 47% silver, 1% palladium and 1% cobalt), with the $431 million increase relative to the prior period quarter being primarily due to a 98% increase in the average realized gold equivalent3 price; partially offset by a 3% decrease in the number of GEOs3 sold.

Cash Costs and Margin
Average cash costs1 in the first quarter of 2026 were $681 per GEO3 as compared to $392 in the first quarter of 2025. This resulted in a cash operating margin1 of $4,279 per GEO3 sold, an increase of 103% as compared with the first quarter of 2025, 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 70% 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.

Cash Flow from Operations
Operating cash flow in the first quarter of 2026 amounted to $766 million, with the $405 million increase from the comparable period of the prior year being due primarily to higher gross margin.

Produced But Not Yet Delivered
As at March 31, 2026, approximately 183,500 GEOs3 were produced but not yet delivered ("PBND") representing approximately 2.8 months of payable production. This increase in the number of months of PBND compared with the preceding four quarters places PBND levels at the mid-point of our guided range of two and a half to three and a half months and was driven primarily by strong quarterly production at Peñasquito.

Balance Sheet (at March 31, 2026)

First Quarter Operating Asset Highlights

Salobo: In the first quarter of 2026, Salobo produced 69,200 ounces of attributable gold, a decrease of approximately 3% relative to the first quarter of 2025, primarily the result of lower grades, partially offset by higher throughput and recoveries.

Antamina: In the first quarter of 2026, Antamina produced 1.6 million ounces of attributable silver, an increase of approximately 48% relative to the first quarter of 2025, primarily due to higher grades and recoveries.

Peñasquito: In the first quarter of 2026, Peñasquito produced 2.6 million ounces of attributable silver, an increase of approximately 46% relative to the first quarter of 2025, primarily the result of higher throughput and grades.

Constancia: In the first quarter of 2026, Constancia produced 0.5 million ounces of attributable silver and 4,600 ounces of attributable gold, a decrease of approximately 4% and 6%, respectively, relative to the first quarter of 2025, primarily due to lower gold and silver recoveries. Mining activities in the Pampacancha pit were completed during the fourth quarter of 2025 and the remaining stockpiled Pampacancha ore was fully processed during January 2026. On May 1, 2026, Hudbay announced that mill throughput rates are expected to increase to more than 90,000 TPD starting in the second half of 2026, with the installation of two pebble crushers and related permit amendments. Hudbay reports it received permit approval to increase annual mill throughput capacity to 31.1 million tonnes from 29.9 million tonnes, providing the new base for the 10% permitted allowance that aligns with the Peru Ministry of Energy and Mines' regulatory change.

San Dimas: In the first quarter of 2026, San Dimas produced 7,300 ounces of attributable gold, a decrease of approximately 13% relative to the first quarter of 2025, primarily the result of lower grades, consistent with their mine plan.

Stillwater: In the first quarter of 2026, the Stillwater mines produced 1,400 ounces of attributable gold and 2,600 ounces of attributable palladium, an increase of approximately 6% for gold and a decrease of approximately 4% for palladium relative to the first quarter of 2025. The increase in gold production was a result of higher throughput and recovery, partially offset by lower grades while the decrease in palladium was a result of lower recoveries.

Blackwater: In the first quarter of 2026, Blackwater produced 0.1 million ounces of attributable silver and 5,000 ounces of attributable gold, primarily the result of higher throughput with the mine achieving commercial production in May 2025. On March 12, 2026, Artemis Gold reported an unplanned mill shutdown due to the failure of a ball mill gearbox, with the mill operations being interrupted for 7 days. Artemis Gold also notes that strong grades during the quarter helped to offset the lower throughput resulting from the interruption, and that they are maintaining their full year production guidance, with plans to make up for the unplanned downtime experienced in Q1.

Voisey's Bay: In the first quarter of 2026, the Voisey's Bay mine produced 657,000 pounds of attributable cobalt, an increase of approximately 22% relative to the first quarter of 2025 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 first quarter of 2026, total Other Gold attributable production was 5,400 ounces, an increase of approximately 616% relative to the first quarter of 2025 due to the initial reported production from the Fenix mine as well as the addition of attributable production from the Hemlo and Goose mines. Notable operational updates for assets included within 'Other Gold' include:

Other Silver: In the first quarter of 2026, total Other Silver attributable production was 1.9 million ounces, an increase of approximately 44% relative to the first quarter of 2025, primarily the result of the resumption of mining at Aljustrel. Notable operational updates for assets included within 'Other Silver' include:

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.

Recent Development Asset Updates

Mineral Park: During the first quarter of 2026, Waterton Copper LP continued to refine ore commissioning of the newly refurbished concentrator at its Mineral Park project. The ramp-up efforts in Q1 2026 were focused on achieving stable throughput and gradually increasing both operating uptime and concentrate production. Copper concentrate sales continued in the first quarter and monthly delivery of silver to Wheaton under the PMPA commenced in January 2026. Ramp-up to commercial production is expected to continue in Q2 2026, with increasing operating volumes throughout the second quarter. At steady state throughput, the fully refurbished mill capacity will be 16.5 Mtpa.

Platreef: On April 13, 2026, Ivanhoe announced that the ramp-up of the Platreef mine is advancing on track, with commercial production expected mid-year. Ivanhoe states that construction of Shaft #3, as well as its associated underground materials-handling and crushing plants, was completed on schedule in late March and is currently undergoing commissioning. Once Shaft #3 ramps up, the Phase 1 concentrator will then be continuously fed with higher-grade production ore. In addition, Shaft #3 will also hoist waste development required in preparation for the Phase 2 expansion, which is on schedule to be completed by the end of 2027.

Fenix: On January 26, 2026, Rio2 Limited ("Rio2") announced the first official gold pour at the Fenix Gold Mine, with construction of critical path items completed on time and on budget, as previously guided.

Kurmuk: On March 31, 2026, Allied announced its shareholders had approved the previously announced definitive agreement with Zijin Gold International Company Limited ("Zijin Gold"), where Zijin Gold will acquire all of the issued and outstanding shares of Allied in cash. Allied states that both companies continue to diligently and cooperatively advance the customary regulatory approvals necessary to complete the arrangement, with the objective of closing in a timely manner within the timeframe set out in the agreement. The agreement provides for an outside date for closing of May 29, 2026, subject to extension in certain circumstances.

Koné: On March 26, 2026, Montage reported that construction at the Koné project is on track for first gold pour in late Q4 2026 through the oxide circuit, while the hard-rock comminution circuit remains on track for completion in Q2 2027. Key process plant achievements include completion of all CIL tanks and ball mill shell installation, oxide sizer completion, foundation concrete pours for pre-leach and tailings thickeners, and advancement of the hard-rock comminution circuit.

Copper World: On January 12, 2026, Hudbay announced the closing of the joint venture transaction with Mitsubishi Corporation, securing a premier, long-term strategic partner for the development of Copper World. On May 1, 2026, Hudbay reported that feasibility activities for Copper World are well under way, with the definitive feasibility study ("DFS") progressing above 85% at the end of March, and on track for completion in mid-2026. Hudbay reports it continues to execute detailed engineering work and other de-risking activities in preparation for a Copper World sanctioning decision expected later in 2026.

Santo Domingo: On April 29, 2026, Capstone Copper Corp. ("Capstone") reported that detailed engineering advanced during the first quarter, alongside continued evaluation of opportunities to optimize district infrastructure. Capstone expects to make a final investment decision on the Santo Domingo Project in Q4 2026.

Cangrejos: On April 28, 2026, it was announced that Ecuador has signed the exploitation contract for the Cangrejos project. Signing this exploitation contract will allow CMOC to move forward with seeking the required construction permits for the mine and its facilities.

Kudz Ze Kayah: On April 13, 2026, BMC Minerals Ltd. ("BMC") announced receipt of a positive decision document issued by the Government of Yukon, Natural Resources Canada and the Department of Fisheries and Oceans Canada, after the Yukon Environmental and Socio-economic Assessment Board had recommended approval of the project in 2020. BMC reports it will now progress mining permit and license applications with the aim to make a final investment decision in late 2027, subject to receipt of permits.

Corporate Development

Antamina: On February 16, 2026, the Company entered into a PMPA with BHP (the "BHP Antamina PMPA") for their 33.75% portion of the silver produced at the Antamina Mine located in Peru. Effective April 1, 2026, Wheaton will receive a combined 67.5% of all the silver produced from Antamina, up from the 33.75% currently delivered under the existing Glencore silver stream. First deliveries under the BHP Antamina PMPA are anticipated to be received at the end of May 2026.

Under the terms of the BHP Antamina PMPA, the Company paid BHP total upfront cash consideration of $4.3 billion on April 1, 2026, being the date of closing. Additionally, the Company will make ongoing payments for the silver ounces delivered equal to 20% of the spot price of silver.

Jervois: On April 1, 2026, the Company entered into a PMPA with KGL (the "Jervois PMPA") for a portion of the gold and silver produced at the Jervois Project located in Australia. In return, the Company also obtained a right of first refusal on any future precious metal streams, royalties, prepays or similar transactions with respect to the Jervois Project. Under the terms of the Jervois PMPA, the Company will pay KGL total upfront cash consideration of $275 million, subject to certain customary conditions. The upfront cash consideration will be paid in a total of six installments, with the first two installments of $16 million each to be made as early deposit payments, once certain conditions are satisfied, and are expected to be paid in the second and third calendar quarters of 2026. The remaining balance of $243 million will be paid in four equal installments over the construction period as various conditions are satisfied. Additionally, the Company will make ongoing payments for the gold and silver ounces delivered equal to 20% of the spot price of gold and silver.

Spanish Mountain: On April 20, 2026, the Company entered into a Royalty Agreement with Spanish Mountain Gold (the "Spanish Mountain Royalty") for a 1.5% net smelter returns royalty on gold and silver production from the Spanish Mountain Gold project. In return, the Company also obtained a right of first refusal on any future precious metal streams, royalties, prepays or similar transactions with respect to the Spanish Mountain Gold Project. Under the terms of the Spanish Mountain Royalty, the Company will pay Spanish Mountain Gold total upfront cash consideration of $55 million, subject to certain customary conditions. The upfront cash consideration will be paid in three installments consisting of a $22.5 million payment made on May 1, 2026, a $12.5 million payment due after 60,000 meters of drilling (expected to be made during Q2-2026), and a $20 million payment due upon receiving approval under the Environmental Assessment Act (British Columbia) for the construction and operation of the project.

1)

All figures in thousands except gold, palladium and platinum ounces produced.

2)

Quantity produced represents the amount of gold, silver, palladium, platinum 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. From April 30, 2025 to October 28, 2025, the fixed gold to silver exchange ratio was revised to 90:1. Effective October 29, 2025, the fixed gold to silver exchange ratio was returned to 70:1.  For reference, attributable silver production from prior periods is as follows: Q1 2026 - 294,000 ounces; Q4 2025 - 329,000 ounces; 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.

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)

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.

7)

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.

8)

GEOs, which are provided to assist the reader, are based on the following commodity price assumptions: $4,800 per ounce gold; $80.00 per ounce silver; $1,500 per ounce palladium; $2,000 per ounce platinum; and $25.00 per pound cobalt; consistent with those used in estimating the Company's production guidance for 2026.

Quantity produced represents the amount of gold, silver, palladium, platinum and cobalt contained in concentrate or doré prior to smelting or refining deductions. Production figures 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 may be updated in future periods as additional information is received.

2)

GEOs, which are provided to assist the reader, are based on the following commodity price assumptions: $4,800 per ounce gold; $80.00 per ounce silver; $1,500 per ounce palladium; $2,000 per ounce platinum; and $25.00 per pound cobalt; consistent with those used in estimating the Company's production guidance for 2026.

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).

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.

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.

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.
