Yeh Jeffrey 4

What Happened

• Jeffrey Yeh, Executive Vice President of RBB Bancorp (RBB), had 1,326 shares issued on 2026-03-20 due to the vesting/conversion of restricted stock units (RSUs). The gross value of those issued shares, based on $20.43/share, is $27,090.
• To satisfy tax withholding on the vesting, 476 of those shares were surrendered/withheld at $20.43/share for $9,725 (a “sell-to-cover”/tax withholding). Net new shares retained by Yeh from this event = 850 shares.

• Prices and values: 1,326 shares @ $20.43 = $27,090 (issued); 476 shares withheld @ $20.43 = $9,725 (tax payment).
• Transaction codes: M = exercise/conversion of a derivative (RSU conversion to common shares); F = payment of tax liability via share withholding.
• Net effect: +850 shares added to Yeh’s holdings from this vesting event.
• Shares owned after transaction: not specified in the Form 4.
• Relevant footnotes: these shares relate to a 03/20/2024 RSU grant that vests in three equal annual installments (footnote F3); once RSUs vest there is no expiration (F1). Filing remarks confirm the shares were issued for RSU vesting and some were used to settle tax withholding.

Context

• This was not an open-market purchase or sale but the routine settlement of equity awards (RSU vesting) with a portion withheld for taxes (common "sell-to-cover"/withholding). Such transactions are standard compensation events and do not by themselves signal a buy or sell decision by the insider.
