Huang Tsu Te 4

What Happened

• Huang Tsu Te, Executive Vice President of RBB Bancorp (RBB), had restricted stock units convert into 744 common shares on 2026-02-20 (recorded as a derivative conversion/exercise). The shares are valued at $22.20 each for a total of $16,517. To cover tax withholding on the vesting event, 307 shares were surrendered/withheld at $22.20 each ($6,815). The conversion line at $0.00 reflects the derivative-to-share settlement rather than a market sale.

Key Details

• Transaction date: 2026-02-20
• Primary conversion: 744 shares @ $22.20 = $16,517 (code M: exercise/conversion of derivative)
• Tax withholding: 307 shares withheld/disposed @ $22.20 = $6,815 (code F: payment of tax liability)
• Shares outstanding after the transaction: not specified in the provided excerpt of the filing
• Footnotes of note:
  • F2: These RSUs vest in three equal annual installments beginning one year after the 02/21/2024 grant (this vesting event relates to that grant).
  • F1, F3, F4 provide additional administrative details about RSU settlement timing, later RSU grants, and a prior corrected Form 4 (administrative amendment regarding RSU grant disclosure).
• Filing date: 2026-02-24; transaction date 2026-02-20 — the Form 4 was filed within the normal reporting window (timely).

Context

• This was an RSU vesting (award conversion), not an open-market purchase or intentional sale for investment reasons. The disposal of 307 shares was a routine tax-withholding settlement, common when restricted awards vest. Derivative code M plus a $0.00 disposition line indicates conversion/settlement of equity awards into shares rather than a cash proceeds sale.
