F1. Represents shares of common stock issued upon the vesting of outstanding performance stock units that were subject to performance criteria other than the issuer's stock price.
F2. In connection with the vesting of performance stock units previously granted on August 16, 2023, Mrs. Hickox's receipt of 6,094 shares of common stock was deferred resulting in Mrs. Hickox's receipt instead of 6,094 shares of deferred stock units into the First Financial Bankshares, Inc. Supplemental Executive Retirement Plan, as amended and restated effective July 26, 2022 (the "SERP"). Mrs. Hickox is therefore reporting the disposition of 6,094 performance stock units in exchange for an equal number of shares of deferred stock units under the SERP, which are payable upon Mrs. Hickox's termination of employment.
