restricted stock units financial

"Mr. Aguiar was awarded (i) 31,977 restricted stock units on August 7, 2023..."

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

performance rights financial

"Mr. Aguiar was awarded performance rights representing the contingent right to receive..."

Performance rights are conditional awards that give employees or executives the promise of receiving company shares or cash only if the business meets specific targets or survives for a set period. They work like a bonus you only get when certain goals are hit, so they matter to investors because they can increase the number of shares outstanding (dilution), signal management’s incentives and confidence in future results, and affect per-share earnings and valuation.

Total Shareholder Return financial

"based on Hecla Mining Company's Total Shareholder Return performance over the 3-year period..."

Total shareholder return is the overall gain an investor gets from owning a stock, combining changes in the share price plus any cash payouts like dividends, and assuming those payouts are reinvested in more shares. Investors use it like a single score that shows the true return on their investment—similar to checking both the growth of a savings account and the interest earned—to compare how well different companies or investments perform over time.

tax liability financial

"To cover his tax liability on those vested units, Hecla Mining Company withheld 21,659."

401(k) Plan financial

"Held as 905.191 units in Mr. Aguiar's 401(k) account under the Hecla Mining Company Capital Accumulation Plan..."

A 401(k) plan is a workplace retirement account that lets employees set aside part of their pay into a tax-advantaged savings pot, often with employers adding matching contributions — like a workplace piggy bank for future income. It matters to investors because the amount people save and how employers fund these plans influence consumer spending, corporate payroll costs and the flow of money into financial markets, which can affect stock prices and company valuations.
