Wheaton is scheduled to hold its Annual and Special Meeting of Shareholders (the “Meeting”) on Friday, May 13, 2022, at 10:30a.m. Pacific Time. At this time, our governments and public health authorities continue to recommend that all Canadians do not congregate in large groups and that we continue to practice social distancing to assist with reducing the impact of COVID-19 on our communities. The board recognizes the importance of in-person engagement with its shareholders, while also being mindful of the health and safety of Wheaton’s shareholders, employees and community. As a result, for this year’s Meeting, Wheaton has adopted an online virtual Meeting platform and we are strongly encouraging all of our shareholders to participate in the Meeting using this online platform. More information on how to use the online platform can be found here.

All shareholders participating in our online virtual Meeting platform will be able to listen to the Meeting live, ask questions online, and for registered shareholders or proxyholders (including non-registered shareholders who have appointed themselves as proxyholder), submit votes in real time. While Wheaton is encouraging our shareholders to participate in our online virtual meeting platform, anyone who nevertheless wishes to attend the Meeting in person must pre-register via email to WheatonAGM2022@wheatonpm.com by 10:30am May 13, 2022 (PST) so that appropriate measures can be put in place to facilitate physical distancing and other precautions to ensure the health and safety of all attendees.
