Hickox Michelle S 4

What Happened Michelle S. Hickox, EVP and Chief Financial Officer of First Financial Bankshares, Inc. (FFIN), had 6,094 performance stock units vest on March 13, 2026. Instead of receiving common shares, the 6,094 vested units were exchanged for 6,094 deferred stock units and credited to the First Financial Bankshares, Inc. Supplemental Executive Retirement Plan (SERP). No market price or cash proceeds are reported for these transactions (price = N/A) because this was a compensation vesting and internal conversion, not an open-market sale or purchase.
