Plumas Bancorp operates as the bank holding company for Plumas Bank, a California state-chartered commercial bank originally founded in 1980. The company's business model is centered on traditional community banking, generating revenue primarily through interest income on its loan portfolio and investment securities, supplemented by non-interest income from service fees and banking charges. Its comprehensive loan portfolio is diversified across commercial real estate, commercial and industrial, agricultural, residential real estate, and construction and land development loans. To fund these lending activities, Plumas Bancorp offers a full suite of deposit products, including checking, savings, money market, and retirement accounts, catering to both commercial and retail customers.
Geographically, the company maintains a strong regional footprint in the Western United States. It operates a network of branches concentrated in Northeastern California and Northwestern Nevada, alongside loan production offices in California and Oregon. Plumas Bancorp focuses on serving small to middle-market businesses, agricultural enterprises, and local retail consumers, emphasizing personalized service and deep local market expertise. The bank's competitive position is significantly bolstered by its nationwide Preferred Lender status with the U.S. Small Business Administration (SBA), allowing it to efficiently process and originate government-guaranteed loans. Through disciplined capital management, organic growth, and strategic regional expansion—such as the acquisition of Cornerstone Community Bancorp—Plumas Bancorp has established itself as a prominent and stable regional financial institution.
