restricted stock units ("RSUs") financial
"Grant of restricted stock units ("RSUs") that vests in full on the earlier of"
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
Stock Option (Right to Buy) financial
"Stock Option (Right to Buy) with an exercise price and expiration date"
Grant Date financial
"vests in full on the earlier of (i) the first anniversary of the Grant Date"
The grant date is the day a company formally gives an employee or contractor the right to receive stock-based compensation, such as stock options or restricted shares. It matters to investors because it fixes key terms—like the price, the start of the ownership clock, and when the award will affect the company’s financial statements and share count—so it can influence dilution, reported expenses, and potential future selling pressure.

"or (ii) the day immediately prior to the date of the next annual meeting of the stockholders"
