The Reporting Person had a total of 914 RSUs vest on March 1, 2026. The shares reported include 8,541 shares of restricted stock subject to vesting conditions. The Performance-Based Stock Options were granted pursuant to the Issuer's Employee Equity Incentive Plan ("EEIP") on March 1, 2023. The extent to which the options were exercisable was dependent upon the Company achieving certain compounded annual growth rate targets based on net revenue growth in Fiscal Year 2024 over Fiscal Year 2022. In February 2025, the Compensation Committee determined that the performance criteria had been achieved, and as such the options will vest in three equal installments on March 1 in the years 2025-2027, contingent on the Reporting Person's continued employment with the Issuer on the applicable vesting dates.
