Explanation of Responses:

Id	Content
F1	Represents shares held by several trusts of which Mr. Dueser is trustee, settlor and beneficiary.
F2	In connection with the vesting on August 16, 2025, of 3,464 restricted stock units previously granted to the reporting person, the reporting person's receipt of 3,464 shares of common stock was deferred resulting in the reporting person's receipt instead of 3,464 shares of deferred stock units into the First Financial Bankshares, Inc. Supplemental Executive Retirement Plan, as amended and restated effected July 26, 2022 (the "SERP"). The reporting person is therefore reporting the disposition of 3,464 restricted stock units in exchange for an equal number of deferred stock units under the SERP, which are payable upon the reporting person's termination.
