Positive

• Deferral into SERP retains executive alignment by preserving equity-linked benefits until termination
• No market sale reported, so the transaction did not increase public float or indicate immediate insider selling

Negative

• Reduction in vested RSUs reported as a disposition (839 RSUs), decreasing immediately vested equity holdings
• Limited visibility on valuation or timing of eventual payout since deferred units are payable upon termination

Insights

Financial Analyst

TL;DR: Transaction is a routine executive deferral with limited immediate market impact; ownership changes are administrative.

The filing documents a standard deferral of vested restricted stock units into deferred stock units under the company SERP. This preserves economic exposure for the executive while deferring receipt until termination, and does not indicate a sale of underlying shares into the market. The change reduces immediately available equity but leaves reported beneficial ownership largely intact at 33,315 shares plus deferred units. For most investors this is neutral, absent additional equity transactions or patterned insider selling.

Corporate Governance Expert

TL;DR: Governance action reflects planned executive benefit administration rather than a governance concern.

The exchange of 839 vested RSUs for deferred stock units under the amended SERP appears to be an administrative implementation of executive compensation policy. The filing shows appropriate disclosure of the disposition and the nature of the indirect interest. There is no indication of unusual acceleration, related-party transfers, or deviations from ordinary award terms disclosed in this Form 4.

Explanation of Responses:

1. In connection with the vesting on August 16, 2025, of 839 restricted stock units previously granted to the reporting person, the reporting person's receipt of 839 shares of common stock was deferred resulting in the reporting person's receipt instead of 839 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 839 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.
