restricted stock financial

"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.

vested financial

"100% of the shares of restricted stock vested immediately on the grant date"

Omnibus Equity Incentive Plan financial

"Astrotech Corporation 2021 Omnibus Equity Incentive Plan"

A single, company-wide plan that lets a business grant different kinds of stock-based pay — such as stock options, shares that vest over time, or other equity awards — to employees, directors and consultants. It matters to investors because it determines how much of the company can be paid out in shares, how quickly those shares enter the market, and how well employees are motivated to grow the business; think of it as a toolbox or menu for paying with ownership stakes that can dilute existing holders and affect company performance.
