3 terms

Restricted Stock financial

"Restricted Stock"

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.

Performance Shares financial

"Performance Shares"

Performance shares are a type of company stock given to executives or employees that only become theirs if the company meets specific goals, like hitting certain profits or growth targets. They motivate leaders to work toward the company’s success, because their additional shares depend on achieving these results.

Rule 144 regulatory

"paragraph (a) of Rule 144"

Rule 144 is a U.S. securities regulation that sets conditions under which restricted or insider-held shares can be legally resold to the public, such as required holding periods, availability of public information, limits on how much can be sold at once, and certain filing requirements. For investors it matters because it determines when previously locked-up shares can enter the market — like a release valve that can increase supply, affect share price, and signal insider intent.
