Restricted Stock Units financial

"Represents shares of common stock issued upon vesting of 25% of the restricted stock units granted on May 1, 2025."

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 obligations financial

"Represents shares of common stock sold by the Issuer to satisfy certain tax withholding obligations with the vesting of the restricted stock units."

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.

2020 Omnibus Incentive Compensation Plan financial

"one share of the Issuer's common stock in accordance with the Issuer's 2020 Omnibus Incentive Compensation Plan."
