“We are proud to serve the Central Valley and Central Coast of California. Our strong commitment to these communities is reflected in our continued solid deposit growth during 2026,” stated Kevin McPhaill, CEO and President. “I am particularly proud of our ability to pivot, as demonstrated by the surge in loan growth in the last couple of months. This shift reflects the team’s laser focus on both loan and deposit growth. In particular, our loan pipeline increased significantly, and we expect this momentum to result in net loan growth in the second half of 2026. Our expense management strategies resulted in a nearly 2% cost reduction in year-to-date expenses compared to the same period last year. We closed the quarter with contagious optimism throughout our Bank, boosting my confidence in what we can accomplish in the next six months and beyond!” concluded Mr. McPhaill.
