Financial Review

Revenues

Revenue in the fourth quarter of 2025 was $865 million (59% gold, 39% silver, 1% palladium

and 1% cobalt) , with the $484 million increase relative to the prior period quarter being

primarily due to a 69% increase in the average realized gold equivalent³ price; and a 35%

increase in the number of GEOs³ sold.

Revenue was $2.3 billion (62% gold, 36% silver, 1% palladium and 1% cobalt) during the

year ended December 31, 2025, with the $1.0 billion increase from 2024 due primarily to a

46% increase in the average realized gold equivalent³ price; and a 23% increase in the

number of GEOs³ sold.

Cash Costs and Margin

Average cash costs¹ in the fourth quarter of 2025 were $597 per GEO³ as compared to $444

in the fourth quarter of 2024. This resulted in a cash operating margin¹ of $3,941 per GEO³

sold, an increase of 76% as compared with the fourth 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 80% 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 in 2025 were $514 per GEO³ as compared to $438 in 2024. This resulted

in a cash operating margin¹ of $3,040 per GEO³ sold, a 53% increase from 2024, a result of

the higher realized price per ounce.

Cash Flow from Operations

Operating cash flow in the fourth quarter of 2025 amounted to $746 million, with the $427

million increase from the comparable period of the prior year being due primarily to higher

gross margin.

Operating cash flows in 2025 amounted to $1.9 billion, with the $877 million increase from

the comparable period of the previous year being due primarily to higher gross margin.

Produced But Not Yet Delivered

As at December 31, 2025, approximately 155,000 GEOs 3 were produced but not yet

delivered (“PBND”) representing approximately 2. 5 months of payable production. This

reduction 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 by a significant increase in quarterly sales volumes during the fourth

quarter.

Balance Sheet (at December 31, 2025)

• Approximately $1.2 billion of cash on hand

• During the fourth quarter of 202 5, the Company made total upfront cash payments of

$646 million relative to the mineral stream interests consisting of:

o Hemlo: $300 million;

o Koné: $156 million;

o Spring Valley: $50 million

o Fenix: $50 million;

o El Domo: $44 million;

o Kurmuk: $44 million; and

o Kudz Ze Kayah: $2 million.

• Subsequent to the quarter, the Company made additional upfront cash payments of $90

million relative to the Spring Valley PMPA ($50 million) and the Marmato PMPA ($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.

• Subsequent to the quarter, the Company announced its financing plan for the additional

silver stream on the Antamina mine, announced on February 16, 2026 . The upfront

payment of $4.3 billion is expected to be paid on or around April 1, 2026, and will be

funded with cash on hand, a new $1.5 billion term loan credit facility and an

approximately $0.9 billion draw on the Company’s existing undrawn $2 billion revolving

credit facility (“RCF”). The details of this financing plan are provided below in the

‘Corporate Development’ section.

Fourth Quarter Operating Asset Highlights

Salobo: In the fourth quarter of 2025, Salobo produced 88,900 ounces of attributable gold,

representing a quarterly record and an increase of approximately 5% relative to the fourth

quarter of 2024, primarily the result of higher throughput and recoveries resulting from

improved efficiencies at Salobo 1 and 2, partially offset by lower grades.

Antamina: In the fourth quarter of 2025, Antamina produced 1.6 million ounces of attributable

silver, an increase of approximately 49% relative to the fourth quarter of 2024, primarily due

to higher grades and recoveries.

Peñasquito: In the fourth quarter of 2025, Peñasquito produced 1.8 million ounces of

attributable silver, a decrease of approximately 26% relative to the fourth quarter of 2024,

- 5 -

primarily the result of lower grades with mining activities having transitioned back into the

Peñasco pit which contains lower silver grades relative to the Chile Colorado pit, partially

offset by higher recoveries . On February 19, 2026, Newmont Corporation (“Newmont”)

reported that silver production at Peñasquito is expected to increase in 2026, largely due to

grades milled, including increased stockpile processing in 2026.

Constancia: In the fourth quarter of 2025, Constancia produced 0.7 million ounces of

attributable silver and 15,400 ounces of attributable gold, a decrease of approximately 25%

and 18%, respectively, relative to the fourth quarter of 2024, primarily due to lower gold and

silver grades. On February 20, 2026, Hudbay Minerals Inc (“Hudbay”) announced that

Constancia is expected to deliver at higher mill throughput rates starting in the second half of

2026 with the installation of pebble crushers. Hudbay reported that 2026 gold production is

expected to be lower than 2025 production, reflecting depletion of the Pampacancha pit in

2025.

San Dimas: In the fourth quarter of 2025, San Dimas produced 8,200 ounces of attributable

gold, an increase of approximately 13% relative to the fourth 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 for the period April 30, 2025 to October 28, 2025. On October 29, 2025, the

gold to silver conversion ratio returned to 70:1.

Stillwater: In the fourth quarter of 2025, the Stillwater mines produced 1,500 ounces of

attributable gold and 2,500 ounces of attributable palladium, a decrease of approximately

30% for gold and 10% for palladium relative to the fourth quarter of 2024, primarily due to

lower grades and recoveries.

Blackwater: In the fourth quarter of 2025, Blackwater produced 0.1 million ounces of

attributable silver and 5,500 ounces of attributable gold, with the mine achieving commercial

production in May 2025 . On December 15, 2025, Artemis Gold Inc. (“Artemis Gold”)

announced that its board of directors approved an expanded Phase 2 development at the

Blackwater mine. This Phase 2 development is a significant addition to the previously

announced Phase 1A project, designed to increase nameplate capacity from 8 Mtpa to 21

Mtpa before the end of 2028.

On March 12, 2026, Artemis Gold reported an unplanned mill shutdown due to the failure of

a ball mill gearbox, with the estimated time to complete repairs and restart mill operations

between 8 to 10 days. Artemis Gold reports that plans are underway to make use of this

interruption to carry out maintenance activities originally planned for Q2 2026. Artemis Gold

notes that while mining related activities are continuing normally, production in Q1 2026 is

expected to be lower than originally anticipated as a result of this mill outage.

Voisey’s Bay: In the fourth quarter of 2025, the Voisey's Bay mine produced 670,000 pounds

of attributable cobalt, an increase of approximately 70% relative to the fourth 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 fourth quarter of 2025, total Other Gold attributable production was 3,400

ounces, an increase of approximately 441% relative to the fourth quarter of 2024 due to the

initial reported production from the Goose mine, which achieved commercial production on

October 6, 2025, and the addition of attributable production from the Hemlo mine. Notable

operational updates for assets included within ‘Other Gold’ include:

• Goose: On February 18, 2026, B2Gold reported that production at the Goose Mine

in 2025 was impacted by crushing plant capacity constraints in the third quarter and

- 6 -

temporary delays in accessing higher-grade ore from the Umwelt underground in the

third quarter and early fourth quarter. Initial near -term crushing circuit modifications,

ordered in late 2025 and scheduled for implementation in the second half of 2026,

are expected to increase average throughput to approximately 3,200 tonnes per day

and eliminate the need for full -time use of the mobile crusher, while studies are

underway to evaluate further enhancements to increase capacity to approximately

4,000 tonnes per day, with decisions on scope and timing expected in the first half of

2026. B2Gold states that production in 2026 is expected to be weighted to the second

half of 2026, with approximately 65% of estimated annual gold production to be

achieved during the third and fourth quarters.

• Marmato: On March 11, 2026, Aris Mining Corporation (“Aris”) reported that

development of the new underground decline to the Bulk Mining Zone at the Marmato

mine is approximately 60% complete and is scheduled for completion in Q3 2026,

ahead of the commissioning of the carbon in pulp plant, which is expected in Q4

2026.

• Hemlo: On November 26, 2025, the Company entered into a PMPA (the “Hemlo

PMPA”) with Hemlo in respect of gold production from the currently operating Hemlo

mine located in Ontario, Canada. On January 29, 2026 Hemlo announced that they

had initiated a 130,000 meter exploration drilling program aimed at extending the mine

life, de -risking the near -term mine plan and identifying near -mine growth

opportunities.

Other Silver: In the fourth quarter of 2025, total Other Silver attributable production was 1.8

million ounces, an increase of approximately 30% relative to the fourth quarter of 2024 .

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 quarter, Waterton Copper LP continued ore commissioning of the

newly refurbished concentrator at its Mineral Park project. The ramp -up efforts in Q4 2025

were focused on mill alignment to handle increasing throughput and gradually increasing both

operating uptime and overall site throughput. First concentrate sales occurred in Q4 2025

and first silver delivery to Wheaton occurred in January 2026. Ramp -up to commercial

production is expected to continue in Q1 2026, with in creasing concentrate production

throughout the first quarter. At steady state throughput, the fully refurbished mill capacity will

be 16.5 Mtpa.

20,000 tonnes per day of ore.

Kurmuk: On February 18, 2026, Allied Gold Corporation (“Allied”) reported that the Kurmuk

project was progressing in line with plan, with advancement at the processing plant and

crushing circuit, mining activities supporting ore stockpiling, and power line construction

advancing toward completion ahead of commissioning. A review of processing capacity was

completed in Q4 2025, and the project is now being executed to accommodate average

throughput of up to 6.4 Mtpa (from 6.0 Mtpa), with pre-commissioning expected in 2026.

On January 26, 2026, Allied announced it has entered into a 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. Subject to the satisfac tion or waiver by the

parties of all necessary closing conditions and the receipt of all required approvals, the

completion of the transaction is anticipated in late April 20269.

Koné: On January 19, 2026, Montage announced that rapid construction progress

continues to be made at its Koné project, where first gold pour through the oxide circuit is

anticipated in late Q4 2026, while the hard-rock comminution circuit remains well on track

for completion in Q2 2027. Since commencement of the project, key milestones achieved

include the erection of all 14 carbon-in-leach tanks, piperack and grid mesh walkways,

completion of the oxide sizer and the delivery of the ball mill to site.

El Domo: On February 4, 2026, Silvercorp reported that during 2025, construction activities

at its El Domo project advanced across site preparation, infrastructure, and water

management works, with approximately $44.5 million spent (about 16% of their revised

budget), including completion of archaeological clearance, significant earthworks and road

construction, camp commissioning, and placement of orders for long‑lead time major

equipment.

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. Hudbay notes that they intend to complete the definitive

feasibility study at Copper World in mid-2026 with final sanctioning decision expected in

2026.

Santo Domingo: On February 17, 2026, Capstone reported that they plan to progress the

financing strategy, detailed engineering and infrastructure optimization opportunities at its

Santo Domingo project towards a sanctioning decision expected in the second half of 2026.

Corporate Development

Spring Valley: On November 6, 2025, the Company entered into a PMPA (the “Spring Valley

PMPA”) with Waterton Gold Corp., a subsidiary of Waterton Gold LP, in respect of gold

production from the Spring Valley project located in Nevada, USA (“Spring Valley”). Under

the terms of the Spring Valley PMPA, the Company is committed to pay Waterton Gold total

upfront cash consideration of $670 million in installments as various conditions are satisfied,

with the initial payment being paid on December 11, 2025. The Company has also provided

a cost overrun facility of up to $150 million, accessible during an availability period

commencing once the full upfront consideration has been paid under the Spring Valley

PMPA.

- 8 -

Hemlo: On November 26, 2025, the Company entered into a PMPA with Hemlo in respect

of gold production from the currently operating Hemlo mine located in Ontario, Canada.

Under the terms of the Hemlo PMPA, which will deliver immediate production and cash flow

to the Company, the Company paid Hemlo total upfront cash consideration of $300 million.

As part of its financing commitment, on October 7, 2025 the Company invested $30 million

(Cdn$42 million) in Hemlo’s equity offering.

Antamina: On February 16, 2026, the Company announced it had entered into a definitive

PMPA with BHP (the “BHP Antamina PMPA”) for their 33.75% portion of the silver produced

at the Antamina Mine located in Peru. Upon closing, 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 Antamina silver stream.

Under the terms of the BHP Antamina PMPA, the Company will pay BHP total upfront cash

consideration of $4.3 billion on closing, subject to certain customary conditions. Additionally,

the Company will make ongoing payments for the silver ounces delivered equal to 20% of

the spot price of silver. The BHP Antamina PMPA is effective April 1, 2026, from which time

the Company will purchase BHP’s 33.75% of the payable silver until a total of 100 million

ounces has been delivered, at which point the Company will purchase 22.5% of the payable

silver for the life of mine. Payable silver will be calculated using a fixed payable factor of

90.0%.

The upfront payment of $4.3 billion will be funded through a combination of existing liquidity

and new financing. Funding sources include estimated cash on hand at closing of

approximately $1.9 billion, including the $1.2 billion cash on hand at December 31, 2025 in

addition to $323 million realized on the disposal of Long -Term Equity Investments . The

remaining balance will be funded through an approximate $0.9 billion draw on the Company’s

Revolving Facility, in addition to a new $1.5 billion non-revolving term loan credit facility

(“Term Loan”) which carries a two-year maturity and aligns with the terms of the Company’s

existing Revolving Facility.

The Term Loan and the RCF provide flexible, non -dilutive financing that may be repaid at

any time without penalty . T he remaining liquidity available from the RCF, in addition to

continued strong cash flows, provides healthy balance sheet capacity. Net debt at closing of

the BHP Antamina PMPA acquisition is currently expected to be approximately $2.4 billion,

assuming estimated approximate incremental cash flows. With the liquidity provided by the

remaining available credit under the $2 billion Revolving Facility coupled with the $500 million

accordion and ongoing operating cash flows, the Company remains well positioned to fund

all outstanding commitments, as well as providing flexibility to acquire additional accretive

mineral stream interests.
