Mr. Sienko was awarded performance rights representing the contingent right to receive between $350,000 and $700,000 worth of Hecla Mining Company common stock based on Hecla Mining Company's Total Shareholder Return performance over the 3-year period (January 1, 2025 to December 31, 2027) relative to our peers. Examples of the potential grant of shares to Mr. Sienko under this plan are as follows: 100th percentile rank among peers = maximum award at 200% of target ($700,000 in stock); 50th percentile rank among peers = target award at grant value ($350,000 in stock), and 0 percentile rank among peers = threshold award below 25% target.
