Routine tax withholding; insider retains substantial share and option stake.

The filing shows a 2,948-share tax-withholding disposition by USCB's President and CEO tied to equity compensation. Code F indicates shares were withheld at $18.45 per share to satisfy tax liabilities, rather than sold in the open market.

Following the transaction, he holds 242,945 common shares plus options on 40,000 shares at $11.35 expiring on September 23, 2029 and 160,000 shares at $12.05 expiring on September 27, 2031. These positions suggest the event is administrative and not a directional bet on the stock.
