Restricted Stock Units financial

"Restricted stock units granted under the 2013 Equity and Incentive Compensation Plan represent a contingent right to receive Enviri common stock"

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.

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.

derivative security financial

"Exercise or conversion of derivative security"

A derivative security is a financial contract whose value comes from the price or performance of something else, such as a stock, bond, commodity, or market index. For investors it acts like an insurance policy or a wager: it can be used to protect against losses, lock in prices, or amplify gains and losses, so it can change a portfolio’s risk and potential return without owning the underlying asset directly.

Equity and Incentive Compensation Plan financial

"Restricted stock units granted under the 2013 Equity and Incentive Compensation Plan represent a contingent right"

vested and settled financial

"The restricted stock units have been vested and settled, as approved on May 18, 2026 by the Enviri Board of Directors"

contingent right financial

"represent a contingent right to receive Enviri common stock on a one-for-one basis"
