F1: Represents an equal number of restricted stock units ("RSUs"). Each RSU represents the right to receive a share of the Issuer's common stock on the date it vests. These RSUs were granted subject to performance- and service-based vesting requirements. On August 5, 2025, the Compensation Committee of the Issuer's Board of Directors certified the level of achievement of the performance-based conditions. As a result, one hundred percent (100%) of the RSUs will vest on August 14, 2025, subject to continued service with the Issuer through such date.

F2: Includes common stock owned and unvested restricted stock units.
