Explanation of responses
- F1Represents shares of restricted stock granted to the Reporting Person pursuant to the Astrotech Corporation 2021 Omnibus Equity Incentive Plan. The shares of restricted stock vest on each of the first three anniversaries of August 13, 2025, such that 100% of the shares of restricted stock granted shall be fully vested on August 13, 2028, subject to Reporting Person's continuous employment with the Issuer through each such applicable anniversary.
Remarks
The original Form 4, filed on July 22, 2026, is being amended to restate the vesting anniversary date in Note (1) as the original Form 4 erroneously indicated that the shares of restricted stock would vest in equal installments on each of the first three anniversaries of August 13, 2026, when, as reported in this amendment the shares of restricted stock vest on each of the first three anniversaries August 13, 2025, such that 100% of the shares of restricted stock granted shall be fully vested on August 13, 2028.
