The following constitutes Amendment No. 3 to the Schedule 13D and 13D/A filed by the undersigned (“Amendment No. 3”). This Amendment No. 3 amends the Schedule 13D filed on August 20, 2018 and Schedule 13D/A filed on May 13, 2021 and November 1, 2022, as specifically set forth herein.

This Amendment No. 3 is being filed to reflect a change in the percentage of outstanding shares of PCB Bancorp held by the undersigned and resulting from the Company’s share repurchase activity and the additional 87,252 shares acquired through open-market purchases, which combined had an aggregate effect of increasing the undersigned’s beneficial ownership by 1% of the outstanding shares of PCB Bancorp from that previously reported.

As of the filing of the Schedule 13D/A on November 1, 2022, the undersigned collectively owned 1,715,648 shares of PCB Bancorp common stock, which represented 11.59% of the outstanding shares of PCB Bancorp. The additional 87,252 shares represented an increase of less than 1% of PCB Bancorp outstanding beneficially owned by the undersigned. However, as a result of recent repurchase activity by PCB Bancorp, the aggregate change in the percentage of outstanding shares of PCB Bancorp that the undersigned’s holding represents has increased to 12.59%, causing the need to file this Amendment No. 3.
