The words “we,” “us,” “our,” or the “Company” refer to California BanCorp and California Bank of Commerce, N.A. collectively and on a consolidated basis. References herein to “California BanCorp,” or the “holding company” refer to California BanCorp on a stand-alone basis. References to the “Bank” refer to California Bank of Commerce, N.A. Since its founding, our franchise has experienced significant growth through acquisitions and our dedication to serving the communities in which we operate. As of December 31, 2025, we had consolidated assets of $4.03 billion and our branch footprint extends throughout California. Community support is integral to who we are, how we operate, and our success in each community we bank. We have deep roots in the communities in which we do business, through donations, regional Advisory Boards, and our employees’ involvement in local nonprofits. We support our communities through philanthropic giving to nonprofit organizations with which we generally have a direct banking relationship (including investments, deposits, and loans) and/or Community Reinvestment Act (“CRA”) service or referral relationships. Our Advisory Boards consist of leaders in the local business communities that offer insights into business conditions in the regional area and introduce us to prospective clients. Our employees are encouraged to volunteer their time to serve their communities in various capacities, including serving on the board of directors of non-profit organizations throughout California. As a relationship-focused community bank, we offer a range of financial products and services to individuals, professionals, and small to medium-sized businesses through our 14 branch offices and 11 commercial banking offices serving California. We have kept a steady focus on our solution-driven, relationship-based approach to banking, providing clients accessibility to decision makers and enhancing value through strong client partnerships. Our lending products consist primarily of construction and land development loans, commercial real estate (“CRE”) loans, commercial and industrial (“C&I”) loans, U.S. Small Business Administration (“SBA”) loans, and consumer loans. Our deposit products consist primarily of demand, money market, and certificates of deposit accounts and we offer treasury management services including online banking, cash vault, sweep accounts, and lockbox services. As of December 31, 2025, we had total consolidated assets of $4.03 billion; total loans, including loans held for sale, of $3.06 billion; total deposits of $3.37 billion; and total shareholders’ equity of $576.6 million. 5 Table of Contents Our Strategy In late 2020, with the appointment of David I. Rainer as Executive Chairman of the Board of Directors of the Company (the “Board”), and the addition of a group of seasoned Southern California banking executives with demonstrated past performance, we began an aggressive plan to tailor our footprint to align with our expanded commercial banking strategy and position ourselves as the commercial bank of choice for small- to medium-sized businesses in Southern California. This resulted in the expansion of the franchise through the opening of regional banking offices and branches in key Southern California markets, with a focus on relationship-based commercial banking, including locations in West Los Angeles, the San Fernando Valley and Ventura.…
