Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) The reporting person elected, in accordance with the Registrant's 2021 Omnibus Stock and Incentive Plan, to exercise his right to have the Registrant withhold 98 shares of the Registrant's common stock to pay income taxes related to vesting of previously granted restricted stock units.
(2) In connection with the vesting on August 16, 2024, of 1,368 restricted stock units previously granted to Mr. Thaxton, Mr. Thaxton's receipt of 1,368 shares of common stock was deferred resulting in Mr. Thaxton's receipt instead of 1,368 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. Thaxton is therefore reporting the disposition of 1,368 restricted stock units in exchange for an equal number of shares of deferred stock units under the SERP, which are payable upon Mr. Thaxton's termination of employment.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
