# Director Raymond Yu resigns from RBB Bancorp board citing governance disagreements over independence and conflicts

## Summary
- Yu resigned effective May 10, 2022, citing disagreements over director independence and conflict-of-interest determinations.
- Board disclosed that directors Peter Chang and Christopher Koo were involved in an undisclosed outside business venture with EVP Simon Pang, but no business with RBB.
- Board initially determined Chang and Koo met Nasdaq independence standards; later withdrew that determination and will investigate Yu's allegations.
- Board acknowledges independent director requirements will continue to be met regardless of Chang and Koo's status.
- Yu's resignation letter also cites concerns about public disclosures and board's failure to address material issues despite repeated requests.
