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. Ruzicka's receipt of 2,370 shares of common stock was deferred resulting in Mr. Ruzicka's receipt instead of 2,370 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. Ruzicka is therefore reporting the disposition of 2,370 performance stock units in exchange for an equal number of shares of deferred stock units under the SERP, which are payable upon Mr. Ruzicka's termination of employment.

FAQ

What did FFIN executive John Ruzicka report in this Form 4 filing?

He reported routine equity compensation vesting and deferral. 2,370 performance stock units vested into common stock, which he then deferred into 2,370 deferred stock units under the Supplemental Executive Retirement Plan, resulting in updated common and deferred stock unit holdings.

Did John Ruzicka buy or sell FFIN shares on the open market?

No open-market buys or sells were reported. The transactions reflect equity awards vesting and an internal deferral election, including a disposition entry back to the issuer, rather than purchases or sales through the public market.

How many FFIN shares and deferred stock units does John Ruzicka hold after the transactions?

He holds 11,986 common shares and 5,837 deferred stock units. These post-transaction balances come from the Form 4, which shows the updated totals following the vesting of 2,370 performance stock units and their deferral into deferred stock units.

What is the significance of the 2,370 deferred stock units reported for FFIN?

The 2,370 deferred stock units represent deferred compensation. They were received instead of taking 2,370 vested common shares immediately, and are credited under the Supplemental Executive Retirement Plan to be paid upon termination of employment.

Why does the Form 4 show both an acquisition and disposition of 2,370 FFIN common shares?

This reflects the deferral of vested performance stock units. 2,370 performance stock units vested into common stock, then the same amount was effectively returned to the issuer as those shares were converted into 2,370 deferred stock units under the retirement plan.
