Explanation of Responses:

Id	Content
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, Mr. Roewe's receipt of 2,539 shares of common stock was deferred resulting in Mr. Roewe's receipt instead of 2,539 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"). Mr. Roewe is therefore reporting the disposition of 2,539 performance stock units in exchange for an equal number of shares of deferred stock units under the SERP, which are payable upon Mr. Roewe's termination of employment.
