Redding, Calif. (JULY 2, 2025) — Plumas Bank, a wholly-owned subsidiary of Plumas Bancorp, announced today the successful completion of its acquisition of Cornerstone Community Bank, uniting two community-driven institutions to strengthen local banking services throughout northern California.
“Our institutions were built on the same foundation: local leadership, deep relationships, and a focus on supporting the communities we serve,” said Andrew Ryback, president and CEO of Plumas Bank. “Bringing the phenomenal team and strong set of clients that Cornerstone has built under the Plumas Bank umbrella expands our ability to deliver the best banking solutions while preserving the values that matter most to our clients.”
The combined entity will operate under the Plumas Bank name resulting in a team of more than 240 employees, 19 branch locations across Northern California and Northwestern Nevada, and a total asset size of $2.3 billion. The merger affects the Cornerstone Community Bank branches in Redding, Anderson and Red Bluff, California. They join Plumas Bank’s existing branches in Redding, Chico and Yuba City. The additional locations provide clients with greater business banking expertise, increased lending capacity and an expanded branch network along the California State Route 99 and US Interstate Highway 5 corridors.
Matthew Moseley, previously President and CEO of Cornerstone, will assume the role of Executive Vice President/Market President at Plumas Bank and oversee the Redding, Anderson and Red Bluff markets at Plumas Bank. More than 50 Cornerstone employees will join Plumas Bank, ensuring continuity for customers and reinforcing the bank’s regional presence.
“Cornerstone has proudly served the Shasta and Tehama communities for nearly two decades,” said Moseley. “Combining with Plumas Bank gives our clients access to expanded capital resources, and a wide array of services, without losing the trusted relationships and community roots we’ve built. This combination was designed with our customers in mind, and I’m confident it will allow us to serve them even better.”
Plumas Bank and Cornerstone teams have worked together for months to prepare for the merger. Clients and community members are encouraged to stop by any one of the Plumas Bank branches in Redding, Anderson or Red Bluff for welcome events July 1 – July 11, 2025.
