DIVIDEND DECLARATION - Wheaton Precious Metals Announces Increase to Quarterly Dividend

VANCOUVER, BC, March 12, 2026 /CNW/ - Wheaton Precious Metals™ Corp. ("Wheaton" or the "Company") is pleased to announce that its Board of Directors has declared its first quarterly cash dividend payment for 2026 of US$0.195 per common share, an 18% increase from the fourth quarterly cash dividend payment for 2025 of US$0.165 per common share. The Company declared record dividends during 2025, totaling US$0.66 per common share.

The first quarterly cash dividend for 2026 will be paid to holders of record of Wheaton common shares as of the close of business on March 31, 2026, and will be distributed on or about April 10, 2026. The ex-dividend trading date is March 31, 2026.

The declaration, timing, amount and payment of future dividends remain at the discretion of the Board of Directors. This dividend qualifies as an 'eligible dividend' for Canadian income tax purposes.

Dividend Reinvestment Plan
The Company has previously implemented a Dividend Reinvestment Plan ("DRIP"). Participation in the DRIP is optional. For the purposes of this quarterly dividend, the Company has elected to issue common shares under the DRIP through treasury at the Average Market Price, as defined in the DRIP, without a discount.

The Company may, from time to time, in its discretion, apply, change or eliminate any discount applicable to Treasury Acquisitions, as defined in the DRIP, or direct that such common shares be purchased in Market Acquisitions, as defined in the DRIP, at the prevailing market price, any of which would be publicly announced.

The DRIP enrollment forms, including direct deposit, are available for download on the Company's website at www.wheatonpm.com, in the 'Investors' section under the 'Shareholder information' and 'Dividends' tabs.

Registered shareholders may also enroll in the DRIP online through the plan agent's self-service web portal.

Beneficial shareholders should contact their financial intermediary to arrange enrollment. All shareholders considering enrollment in the DRIP should carefully review the terms of the DRIP and consult with their advisors as to the implications of enrollment in the DRIP.
