Key Terms

4 terms

Common Stock financial

"The security title for the reported transaction is 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.

unvested restricted stock awards financial

"Includes 200 shares underlying unvested restricted stock awards granted to the Reporting Person"

grant date financial

"100% of the shares underlying the restricted stock awards will vest on 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.

vest financial

"100% of the shares underlying the restricted stock awards will vest on the one-year anniversary"

A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.
