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:

o Spring Valley: $50 million; and

o Marmato: $40 million; partially offset by

o 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:

o Antamina BHP: $4.3 billion;

o Koné: $156 million; and

o 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 through put 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 quarte r 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 acc ess 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.
