Restricted Stock Units financial

"The Company granted Mr. Piche 150,000 RSUs under the Company's 2020 Omnibus Incentive 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.

2020 Omnibus Incentive Plan financial

"granted Mr. Piche 150,000 RSUs under the Company's 2020 Omnibus Incentive Plan."

vesting financial

"The RSUs will vest in four tranches of 75,000 on the first anniversary, and 25,000 each"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
