4 terms

initial award of stock options financial

"Represents the initial award of stock options for his service as director."

annual award of stock options financial

"Represents the annual award of stock options for his service as director."

vesting date financial

"subject to the director's continued service with the Company or an affiliate through the vesting date."

Grant Date financial

"following the Grant Date on the earlier to occur during each such 12-month period"

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.
