Key Terms

4 terms

restricted stock units financial

"Grant of restricted stock units vesting in full on the earlier of the first anniversary"

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.

grant date financial

"vesting in full on the earlier of the first anniversary of the grant date or the next annual stockholders' meeting"

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.

annual stockholders' meeting financial

"the next annual stockholders' meeting that occurs at least 50 weeks after the prior year's meeting"

continued services as a director financial

"subject to the Reporting Person's continued services as a director of the Issuer through the vesting date"
