The company is registered with the Board of Governors of the Federal Reserve System as a bank holding company for California Bank of Commerce, N. A. under the Bank Holding Company Act of 1956, as amended. California Bank of Commerce, N. A. operates under a federal charter and its primary regulator is the Office of the Comptroller of the Currency. The bank also has a wholly owned subsidiary, BCAL OREO1 LLC, which was incorporated to hold other real estate owned and other assets acquired through foreclosure. The company offers a range of loan and deposit products to individuals, professionals, and small to medium sized businesses. As of December 31, 2025, it held consolidated assets of $4.03 billion, operated 14 branch offices and 11 commercial banking offices, and reported total loans of $3.06 billion and total deposits of $3.37 billion.

California BanCorp generates revenue primarily from interest income on its loan portfolio, which includes construction and land development loans, commercial real estate loans, commercial and industrial loans, Small Business Administration loans, and consumer loans. As of December 31, 2025, construction and land development loans represented 4.4% of the loan portfolio, commercial real estate loans represented 60.0%, commercial and industrial loans represented 20.0%, Small Business Administration loans represented 5.9%, and consumer loans represented a minimal share. Interest income from these loans is the main driver of the bank's net interest margin. Additional revenue comes from fees on deposit accounts, treasury management services such as online banking, cash vault, sweep accounts, and lockbox processing, and gains from the sale of loans or securities. The bank also earns fee income from wealth management services and other ancillary offerings, though these represent a smaller portion of total revenue. Non interest income provides a supplementary contribution to overall earnings.

California BanCorp positions itself as a relationship focused community bank that serves small and medium sized businesses across California, differentiating itself through localized decision making, personal relationships cultivated by its officers and employees, and a deep understanding of regional market needs. It competes with larger national banks, regional financial institutions, credit unions, and fintech lenders that may offer broader product suites or lower rates, but relies on its community engagement, advisory boards, and tailored lending approach to attract and retain clients. The company emphasizes relationship banking, seeking to develop long term connections with customers and the communities they serve. California BanCorp highlights its local advisory boards composed of business leaders who provide insight into regional economic conditions and introduce the bank to prospective clients. The bank notes that California has a high concentration of small businesses and a declining number of locally headquartered banks, presenting a growth opportunity for a dedicated commercial bank focused on relationship based lending.

The company serves a diverse customer base that includes individuals, professionals, and small to medium sized businesses operating in sectors such as manufacturing, wholesale distribution, professional services, commercial real estate, healthcare, hospitality, commercial contracting, and non profit organizations. It also works with business owners trusts, limited liability companies, partnerships, associations, and governmental authorities. The bank's community involvement includes charitable donations to nonprofit organizations with which it often has a direct banking relationship, participation in regional advisory boards, and employee volunteer activities with local nonprofits. No individual client names are disclosed in the filing.
