Liu Vincent 4

What Happened

• Vincent Liu, Executive Vice President of RBB Bancorp (RBB), had 1,203 restricted stock units convert to common shares on 2026-01-16 (recorded as an exercise/conversion). The shares were valued at $21.56 each for a total grant value of $25,937.
• To cover tax withholding obligations related to the vesting, 496 of those shares were surrendered/withheld at $21.56 each ($10,694). Net shares retained from this vesting: 707 shares.
• This was not an open-market purchase or a discretionary sale for investment purposes; it was routine RSU vesting with shares withheld for taxes.

Key Details

• Transaction date: 2026-01-16; Form 4 filed: 2026-01-21 (filed one business day late relative to the 2-business-day filing rule).
• Acquired: 1,203 shares at an attributed price of $21.56 (total $25,937).
• Disposed (tax withholding): 496 shares at $21.56 (total $10,694).
• Derivative conversion: the RSUs were converted into shares (one line shows the derivative conversion at $0.00 reflecting the conversion).
• Shares owned after the transaction: not disclosed in the provided summary of the Form 4.
• Footnotes clarify RSU terms: vested RSUs may have no expiration once vested (F1); these RSUs vest in three equal annual installments per the noted grant dates (F2–F4); and RSU grants are settled in common stock (F5).

Context

• This is a routine compensation event (RSU vesting) with a portion of shares withheld to satisfy tax withholding (code F). Such withholding dispositions are common and do not necessarily indicate buying or selling intent by the insider.
• For derivative/option-type filings, the important takeaway is the conversion of RSUs into shares and the tax-related withholding sale, not an opportunistic market sale.
