restricted stock units financial

"The restricted stock units shall fully vest on the earlier of the one-year 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.

Common Stock financial

"security_title": "Common Stock""

Common stock represents ownership shares in a company, giving investors a stake in its success and a say in important decisions through voting rights. It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.

grant date financial

"vest on the earlier of the one-year 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.
