Explanation of Responses:

1. Reflects grant of restricted stock units (RSUs) which vest in three approximately equal installments on each of the three anniversaries of the grant date.

2. In connection with the vesting on August 14, 2025, of 453 restricted stock units previously granted to the reporting person, the reporting person's receipt of 453 shares of common stock was deferred resulting in the reporting person's receipt instead of 453 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 453 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.

3. The options vest 33.33% after one year from the grant date, 66.66% after the second year, and 100% after the third year.
