4 terms

performance share unit financial

"Represents shares issued upon vesting and settlement of performance share unit awards"

A performance share unit (PSU) is a form of executive or employee pay that promises shares (or the cash value of shares) only if the company meets specific performance targets over a set period. Think of it like a bonus cheque that only arrives if the company hits agreed goals — it aligns managers’ rewards with business results and signals to investors how leadership is being incentivized to grow value over time.

total shareholder return financial

"based on the total shareholder return of Enviri common stock"

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.

S&P 600 Industrials Index financial

"relative to the S&P 600 Industrials Index"

tax-withholding disposition financial

"Payment of exercise price or tax liability by delivering securities"

A tax-withholding disposition is an event or transaction—such as selling or transferring securities, exercising options, or receiving compensation—that triggers a requirement to hold back part of the payment and remit it to tax authorities. It matters to investors because it reduces the cash they receive immediately and can change the timing and amount of taxable income, like a cashier taking a portion of your sale proceeds to pay taxes before you get the rest.
