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 2,989 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.
