restricted stock financial

"400 shares of restricted stock vested on September 23, 2026"

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.

tax liability financial

"Payment of tax liability by delivering or withholding securities"

vested financial

"320 shares of restricted stock vested on September 24, 2026"
