Footnotes

Performance-Based Restricted Stock Units that were previously reported on February 13, 2026, each of which represents a contingent right to receive one share of common stock of ATEN, with vesting subject to the achievement of specified levels of the volume weighted average closing prices of a share of ATEN common stock during any one hundred (100) day trading period between February 12, 2026 and February 12, 2030. The second achievement date occurred on April 27, 2026, as certified by the compensation committee of ATEN, resulting in 65,758 units meeting the appropriate performance-based conditions. However, these shares remain subject to time-based vesting conditions and will therefore vest as to one-half (1/2) on May 14, 2026 and an additional one-fourth (1/4) on each of the first and second anniversaries of April 27, 2026, subject to continued employment. These shares are reflected on Table I.; The amount of securities beneficially owned following the reported transaction has been corrected to reflect a clerical error in the previous filing on May 6, 2026. The correct number of shares meeting the appropriate performance-based condition for this award reported on the Form 4 filed by the reporting person on May 6, 2026 should have been 65,758, not 65,753, as previously reported.
