restricted stock units (RSUs) financial
"These shares are represented by restricted stock units (RSUs) granted under the Second Amended and Restated 2018 Stock Incentive Plan."
Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.
Stock Option (Right to Buy) financial
"Stock Option (Right to Buy) with an exercise price of 298.4800 per share on common stock."
Second Amended and Restated 2018 Stock Incentive Plan financial
"RSUs granted under the Second Amended and Restated 2018 Stock Incentive Plan."
vesting financial
"The RSUs will vest in full upon the earlier of the first anniversary of the grant date and the date of any earlier retirement or resignation."
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.
