Key Terms

3 terms

restricted stock financial

"Award of restricted stock to non-employee director vesting 100%"

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

non-employee director financial

"Award of restricted stock to non-employee director vesting 100%"

annual meeting of shareholders financial

"vesting 100% upon the date of the next annual meeting of shareholders"

A yearly gathering where a company’s owners (shareholders) vote on key items like electing the board, approving executive pay, and ratifying auditors, and receive updates on performance and strategy. Think of it as an annual town hall for owners: it matters to investors because outcomes and disclosures can affect leadership, corporate direction, dividend and governance policies, and therefore the company’s risk and potential return.
