Restricted Stock Units financial
"Each restricted stock unit ("RSU") represents a contingent right to receive one share of Novavax, Inc. common stock."
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.
Stock Option (Right to Buy) financial
"Stock Option (Right to Buy) with 21,270 shares underlying Novavax common stock."
Amended and Restated 2015 Stock Incentive Plan financial
"shares subject to this option grant under the Amended and Restated 2015 Stock Incentive Plan, as amended, will vest"
vesting financial
"One hundred percent (100%) of the RSUs subject to this grant will vest on the first anniversary of the June 18, 2026 grant date"
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.
