Restricted Stock Units financial

"Represents restricted stock units ("RSUs") that were granted under the Issuer's 2020 Incentive Award Plan"

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.

Incentive Award Plan financial

"granted under the Issuer's 2020 Incentive Award Plan on March 1, 2023"

An incentive award plan is a formal program that rewards employees, executives, or directors with cash, stock, options, or other pay when the company meets set goals or performance targets. Like a sales commission or a loyalty program that pays out when you hit milestones, it’s designed to align staff behavior with company objectives; investors care because it affects a company’s costs, share count (dilution), leadership incentives, and long-term value creation.

Amended and Restated 2020 Incentive Award Plan financial

"granted under the Issuer's Amended and Restated 2020 Incentive Award Plan on March 1, 2024"
