4 terms

restricted common stock financial

"Represents restricted common stock that vests on the earlier to occur of..."

Restricted common stock is company shares that carry limits on selling or transferring for a set period or until certain conditions are met, like time-based vesting or regulatory clearance. Think of them as shares in a locked box that gradually open; they can become freely tradable later but initially reduce the number of shares available on the market. Investors watch restricted stock because its eventual release can change a company’s share supply, affect stock price, and influence control and dilution.

annual meeting of stockholders financial

"vests on the earlier to occur of (i) the next annual meeting of stockholders..."

grant date financial

"or (ii) the first anniversary of the grant date, provided that the reporting person..."

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.

continuous service financial

"provided that the reporting person remains in continuous service with the issuer..."
