FIRST QUARTER 2022 FINANCIAL RESULTS

VANCOUVER, BCMay 5, 2022 /PRNewswire/ - "Wheaton once again had a solid start to the year, generating over $210 million in operating cash flow and continuing to return value to our shareholders through our competitive dividend," said Randy Smallwood, President and Chief Executive Officer of Wheaton Precious Metals. "In the first three months of 2022, we added two new streams and increased our interest in a pre-existing stream. In addition, we took a significant step in strengthening our environmental, social and governance strategy by formalizing our climate change policy, including setting a goal of reaching net zero carbon emissions by 2050. The year is off to a good start, and I look forward to advancing on all of our initiatives throughout the year in order to continue building a strong, sustainable business, that delivers value and growth to all of our stakeholders."
