Restricted Stock Units financial

"Represents shares of common stock issued upon vesting of 25% of the restricted stock units"

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

"shares of common stock sold to satisfy certain tax withholding obligations"

Omnibus Incentive Compensation Plan financial

"in accordance with the Issuer's 2020 Omnibus Incentive Compensation Plan"

An omnibus incentive compensation plan is a single, flexible program that lets a company grant different kinds of pay — such as cash bonuses, stock options, restricted stock, or performance awards — to employees, executives and directors. Investors care because the plan affects how much ownership can be given away (dilution), how much the company spends on pay, and whether executives’ goals are aligned with shareholders, much like a menu that decides what rewards staff can pick and how costly they are.
