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)

●

Approximately $2.2 billion of cash on hand

●

During the first quarter of 2026, the Company made net upfront cash payments of $60 million relative to the mineral stream interests consisting of:

^○

Spring Valley: $50 million; and

^○

Marmato: $40 million; partially offset by

^○

a repayment of $30 million relative to the Santo Domingo PMPA, with this amount to be re-advanced at a later date.

●

Over the same period, the Company monetized select long term equity investments, generating $323 million of cash proceeds, resulting in a realized gain before tax of $152 million.

●

Subsequent to the quarter, the Company made additional upfront cash payments of $4.5 billion relative to the mineral stream interests consisting of:

^○

Antamina BHP: $4.3 billion;

^○

Koné: $156 million; and

^○

Spanish Mountain: $22.5 million.

●

On April 1, 2026, the Company made the $4.3 billion upfront payment relative to the BHP Antamina PMPA. The upfront payment was funded through a combination of the cash on hand at closing, a draw on the Company’s previously undrawn $2.0 billion Revolving Facility and a new $1.5 billion term loan (“Term Loan”). The Revolving Facility and the Term Loan provide flexible, non-dilutive financing that may be repaid at any time without penalty.

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.

- 5 -

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:

●

Goose: On April 19, 2026, B2Gold provided an update on a near-term operational plan related to a fire that occurred in certain areas of the crushing circuit at the Goose mine on April 16, 2026. B2Gold confirmed that there were no injuries reported and no medical treatment required related to the fire and the damage was localized to the crushing circuit area. A preliminary revised mill processing plan has been developed for Q2 2026 based on the use of mobile crushers feeding crushed ore directly to the fine ore stockpile while repairs to the crushing circuit related to the fire are completed. B2Gold estimates the repairs will be completed in Q3 2026. B2Gold reports that Q2 production is expected to be approximately 50% lower than Q1 and about 30% below the original Q2 plan, primarily due to lower throughput levels.

●

Marmato: On April 17, 2026, Aris reported a significant construction milestone at its Marmato gold mine with the underground development crosscut now connecting the new surface decline to the existing underground development, establishing continuous underground access from surface, where the new 5,000 tonne per day CIP plant is under construction, to the existing workings. The connection supports the next phases of mine development, infrastructure installation and operational readiness for the Marmato bulk mine which is on schedule for first gold in Q4 2026.

●

Hemlo: On April 28, 2026, Hemlo Mining Corp. (“Hemlo Mining”) announced that during its first full quarter of ownership, the successful transition of an underground mining contractor workforce to owner-operated was completed two weeks ahead of schedule, with 97% of the contractor workforce accepting positions as part of the transition. Hemlo Mining reported that various maintenance activities were undertaken during the quarter, with the most significant tasks being the refurbishment of an underground crusher and the replacement of the hoist cable, which was completed ahead of schedule.

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:

●

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.

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.

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

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.

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.

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.

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.

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).


		Three Months Ended March 31
(in thousands, except for per share amounts)		2026		2025

Net earnings	$	582,044	$	253,984
Add back (deduct):
(Gain) loss on fair value adjustment of share purchase warrants held		928		(623)
Deferred income tax (expense) recovery recognized in the Statement of OCI		-		(2,351)
Other		(200)		(185)

Adjusted net earnings	$	582,772	$	250,825

Divided by:
Basic weighted average number of shares outstanding		454,044		453,692
Diluted weighted average number of shares outstanding		454,955		454,428

Equals:
Adjusted earnings per share - basic	$	1.284	$	0.553
Adjusted earnings per share - diluted	$	1.281	$	0.552

- 19 -

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).


	Three Months Ended March 31

(in thousands, except for per share amounts)	2026		2025

Cash generated by operating activities	$	765,823	$	360,793

Divided by:
Basic weighted average number of shares outstanding		454,044		453,692
Diluted weighted average number of shares outstanding		454,955		454,428

Equals:
Operating cash flow per share - basic	$	1.687	$	0.795
Operating cash flow per share - diluted	$	1.683	$	0.794

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.


	Three Months Ended March 31

(in thousands, except for gold and palladium ounces sold and per unit amounts)	2026			2025
Cost of sales	$	202,095		$	151,328
Less: depletion		(76,852	)		(76,693	)
Less: cost of sales related to delay ounces¹		(1,514	)		(864	)

Cash cost of sales	$	123,729		$	73,771
Cash cost of sales is comprised of:
Total cash cost of gold sold	$	52,877		$	49,512
Total cash cost of silver sold		68,337			23,186
Total cash cost of palladium sold		901			423
Total cash cost of cobalt sold ²		1,614			650
Total cash cost of sales	$	123,729		$	73,771
Divided by:
Total gold ounces sold		95,072			111,297
Total silver ounces sold		5,049			4,483
Total palladium ounces sold		2,906			2,457
Total cobalt pounds sold		309			265
Equals:
Average cash cost of gold (per ounce)	$	556		$	445
Average cash cost of silver (per ounce)	$	13.53		$	5.17
Average cash cost of palladium (per ounce)	$	310		$	172
Average cash cost of cobalt (per pound)	$	5.23		$	2.46

The cost of sales related to delay ounces is a non-cash expense. Please see the Company’s MD&A for more information.

- 20 -

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.

Total cash operating margin of silver sold		358,433		121,751
Total cash operating margin of palladium sold		4,008		1,949
Total cash operating margin of cobalt sold		7,138		2,756

Total cash operating margin	$	777,740	$	396,640
Divided by:
Total gold ounces sold		95,072		111,297
Total silver ounces sold		5,049		4,483
Total palladium ounces sold		2,906		2,457

Cash operating margin per silver ounce sold	$	70.99	$	27.16
Cash operating margin per palladium ounce sold	$	1,379	$	793
Cash operating margin per cobalt pound sold	$	23.12	$	10.42

1) The cost of sales related to delay ounces is a non-cash expense. Please see the Company’s MD&A for more information.

These non-GAAP measures do not have any standardized meaning prescribed by 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. For more detailed information, please refer to Wheaton’s MD&A available on the Company’s website at www.wheatonpm.com and posted on SEDAR+ at www.sedarplus.ca.

Accordingly, readers should not place undue reliance on forward-looking statements and are cautioned that actual outcomes may vary. The forward-looking statements included herein are for the purpose of providing readers with information to assist them in understanding Wheaton’s expected financial and operational performance and may not be appropriate for other purposes. Any forward-looking statement speaks only as of the date on which it is made, reflects Wheaton’s management’s current beliefs based on current information and will not be updated except in accordance with applicable securities laws.

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, 2025, which was filed on March 31, 2025 and other continuous disclosure documents filed by Wheaton since January 1, 2026, 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.
