Insights

Corporate Governance Expert

TL;DR: Compensation awards align with retention and long-term incentive structures without immediate cash transfer.

The filing documents customary equity-based compensation and deferral mechanics for an executive officer. The grant of 1,281 RSUs with three-year vesting and an option award exercisable through 2035 are standard retention and alignment tools. The conversion of 453 vested RSUs into deferred stock units under the SERP indicates utilization of the company's executive retirement arrangement rather than immediate receipt of shares.

Compensation Analyst

TL;DR: Equity awards and option terms provide multi-year upside exposure; vesting schedule limits near-term share dilution.

The employee stock option at a $36.43 strike for 4,302 shares and RSU grants that vest over three years create staged ownership transfer and potential future dilution when vested/exercised. The SERP deferral of 453 vested RSUs postpones share delivery until termination events, preserving current share counts while securing executive benefits.

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.
