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	Represents shares held by several trusts of which Mr. Dueser is trustee, settlor and beneficiary.
F3	Represents shares that are owned by a family limited partnership of which Mr. Dueser serves as manager of the general partner and to which he disclaims beneficial ownership with respect to 353,253 shares. This report should not be deemed an admission that Mr. Dueser is the beneficial owner of these shares for purposes of Section 16 or any other purpose.
F4	In connection with the vesting of performance stock units previously granted on August 16, 2022, Mr. Dueser's receipt of 15,591 shares of common stock was deferred resulting in Mr. Dueser's receipt instead of 15,591 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. Dueser is therefore reporting the disposition of 15,591 performance stock units in exchange for an equal number of shares of deferred stock units under the SERP, which are payable upon Mr. Dueser's termination of employment.
F5	Represents shares that are owned by a family limited partnership of which Mr. Dueser serves as manager of the general partner and to which he disclaims beneficial ownership with respect to 291,125 shares. This report should not be deemed an admission that Mr. Dueser is the beneficial owner of these shares for purposes of Section 16 or any other purpose.
