Operational Overview

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.

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.
