First Financial Bankshares (FFIN) CEO defers vested performance stock

Rhea-AI Filing Summary

FIRST FINANCIAL BANKSHARES INC CEO and President David William Bailey reported compensation-related equity transactions with no open-market trading. On March 13, 2026, he received 2,878 deferred stock units linked to common stock in connection with vesting of previously granted performance stock units.

Footnotes explain that 2,878 performance stock units vested into common stock and, instead of taking those shares directly, Bailey deferred receipt into the company’s Supplemental Executive Retirement Plan as deferred stock units. As part of this process, 2,878 common shares were issued and an equal number were disposed back to the issuer.

Following these transactions, Bailey directly holds 20,872 shares of common stock and 6,581 deferred stock units. The filing reflects routine equity compensation and deferral elections rather than discretionary buying or selling of shares in the market.

1. Represents shares of common stock issued upon the vesting of outstanding performance stock units that were subject to performance criteria other than the issuer's stock price. In connection with the vesting of performance stock units previously granted on August 16, 2023, Mr. Bailey's receipt of 2,878 shares of common stock was deferred resulting in Mr. Bailey's receipt instead of 2,878 shares of deferred stock units into the First Financial Bankshares, Inc. Supplemental Executive Retirement Plan, as amended and restated effective July 26, 2022 (the "SERP"). Mr. Bailey is therefore reporting the disposition of 2,878 performance stock units in exchange for an equal number of shares of deferred stock units under the SERP, which are payable upon Mr. Bailey's termination of employment.
