Insights

Financial Analyst

TL;DR: Compensation-related equity grant with deferral; does not materially change effective ownership.

The 12,352 RSU grant increases potential future equity compensation and vests over three years, aligning executive incentives with shareholder outcomes. The conversion of 4,757 vested RSUs into deferred stock units under the SERP defers taxable and cash settlement events until termination, indicating a routine executive compensation election rather than an immediate sale. Reported indirect holdings via trusts and partnerships represent substantial economic exposure to FFIN while disclaimers limit reported beneficial ownership for certain partnership shares. Overall, these transactions are compensation- and estate-structure driven and appear routine.

Corporate Governance Expert

TL;DR: Governance signal: standard CEO equity grant and use of deferral plan; disclosures are consistent with governance norms.

The filing documents a standard restricted stock unit award and an internal deferral into the company SERP on vesting. Use of trusts and family limited partnerships to hold shares is disclosed with appropriate beneficial ownership disclaimers. The report was filed by an attorney-in-fact and includes explanations for vesting and deferral mechanics. From a governance perspective, this is routine insider compensation and estate planning disclosure without indications of atypical related-party transactions or governance red flags in the filing text.

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. Represents shares held by several trusts of which Mr. Dueser is trustee, settlor and beneficiary.

3. In connection with the vesting on August 14, 2025, of 4,757 restricted stock units previously granted to the reporting person, the reporting person's receipt of 4,757 shares of common stock was deferred resulting in the reporting person's receipt instead of 4,757 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 4,757 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.
