restricted stock units financial

"Reflects a grant of restricted stock units ("RSUs") made to the Reporting Person"

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.

2021 Incentive Award Plan financial

"made to the Reporting Person under the Issuer's 2021 Incentive Award Plan"

par value financial

"one share of the Issuer's common stock, par value $0.001 per share"

Par value is the fixed amount printed on a bond or stock that represents its original value when issued. It’s like the face value of a coin or bill—what the issuer promises to pay back or the starting price of a stock—though it often doesn’t change with market prices. It matters because it helps determine certain financial details, like how much the company will pay back at maturity.
