Wheaton Precious Metals is one of the largest precious metal streaming companies in the world that generates its revenues primarily from the sale of gold, silver and palladium. As of December 31, 2020, the Company has entered into long-term purchase agreements with different mining companies, for the purchase of precious metals and cobalt. Following the PMPAs, Wheaton acquires metal production from the counterparties for an initial upfront payment plus an additional cash payment for each ounce or pound delivered that is fixed by contract, generally at or below the prevailing market price. The company's production profile is driven by the volume of metal production at its various mining assets. The primary drivers of the company's financial results are the volume of metal production at the various mines to which the PMPAs relate and the price realized by Wheaton upon the sale of the metals received.
