Liu Vincent 4

What Happened

• Vincent Liu, Executive Vice President of RBB Bancorp (RBB), had restricted stock units (RSUs) vest on 2026-02-20. The vesting resulted in 932 shares being issued (valued at $22.20 each, total ~$20,690). To satisfy tax withholding obligations, 384 of those shares were surrendered/withheld (384 × $22.20 = ~$8,525).
• The filing also shows the RSU/derivative conversion entries (M code) indicating the RSUs converted into common stock with no exercise price (reported as 932 shares @ $0.00 for the derivative line).

Key Details

• Transaction date: 2026-02-20; Filing date: 2026-02-24.
• Shares issued on vesting: 932 @ $22.20 (total ~$20,690).
• Shares disposed/withheld for tax: 384 @ $22.20 (total ~$8,525) — transaction code F (tax withholding).
• Derivative conversion: 932 shares reported as converted (M) at $0.00 — indicates RSUs settled into common stock rather than a cash exercise.
• Shares owned after the transaction: not disclosed in the provided report.
• Relevant footnotes: F1 (no expiration once RSUs vest), F2/F3 (RSUs vest in three equal annual installments starting one year after grant dates 02/21/2024 and 03/20/2024), F4 (Form 4 clarified RSU grants will be settled in common stock).
• Remarks in the filing: shares were issued for vesting of the 02/21/2024 RSU grant and shares were disposed to settle tax withholding.

Context

• This was RSU vesting/settlement (compensation), not an open-market buy or a voluntary sale; withholding shares for taxes is a routine administrative action and not necessarily a signal of sentiment. The derivative entries at $0.00 reflect conversion/settlement of RSUs into common stock rather than a paid option exercise.
