restricted stock financial
"Represents shares of restricted stock granted to the Reporting Person"
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.
2021 Omnibus Equity Incentive Plan financial
"pursuant to the Astrotech Corporation 2021 Omnibus Equity Incentive Plan"
grant date financial
"100% of the shares of restricted stock vested immediately on 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.
