Wheaton Precious Metals Recognized by Corporate Knights as one of

the 2026 Global 100 Most Sustainable Corporations

Vancouver, British Columbia – Wheaton Precious Metals™ Corp. (“Wheaton” or the “Company”)

is pleased to announce it has been named once again to Corporate Knights’ 2026 Global 100

Most Sustainable Corporations list, marking the third consecutive year of recognition for

leadership in sustainable value creation.

This year’s Global 100 ranking reflects Corporate Knights’ updated methodology, which

evaluates sustainable investments and sustainable revenue. A key element of the Global 100

scoring framework assesses how Wheaton’s streaming business advances the clean economy

and reflects the responsible operational standards of our mining partners.

“Being recognized again in 2026 reinforces that sustainability is foundational to how we create

long‑term value. It directly reflects the caliber of our mining partners and the critical importance

of mining to the clean economy,” said Randy Smallwood, Chief Executive Officer of Wheaton.

“We believe that pursuing the highest standards across our portfolio is essential to Wheaton’s

growth and supports our goal of delivering superior, long-term returns to all of our stakeholders.

This ranking validates that our approach is working.”

“Furthermore, our commitment to advancing climate solutions and supporting clean

technologies within the mining industry remains central to our strategy,” Mr. Smallwood added,

referencing the company’s Future of Mining Challenge, designed to accelerate efficiency and

environmental innovation across the sector.

Through the Future of Mining Challenge, Wheaton has invited cleantech companies from

around the world to submit solutions that address sustainable water management in mining. The

winner of the challenge, to be announced in March 2026, will be awarded US$1,000,000 to

advance their technology.

Corporate Knights’ 2026 ranking of the world’s 100 most sustainable corporations is based on a

rigorous assessment of all publicly listed companies with revenue over US$1 billion. Wheaton

will also be included in the Global 100 Index, which represents a benchmark for sustainability

excellence. The Company was also named by Corporate Knights as one of the 2025 Best 50

Corporate Citizens in Canada.
