RBB Bancorp (RBB) EVP updates RSU and PSU awards in Form 4/A

Rhea-AI Filing Summary

RBB Bancorp executive Jeffrey Yeh, an EVP, reported an amended insider transaction and equity award details. On 01/16/2026, he acquired 842 shares of RBB Bancorp common stock at $21.56 per share through the exercise (code M) of previously granted restricted stock units, bringing his directly held common stock to 57,642 shares.

A prior filing had overstated certain RSU and PSU grants from 05/08/2025, and this amendment clarifies that those grants settle in common stock and corrects remaining RSUs from the 03/20/2024 grant to 2,652 units.
