Nature of Operations [Text Block]	NOTE 1 - BUSINESS DESCRIPTION RBB Bancorp is a bank holding company registered under the Bank Holding Company Act of 1956, as amended. RBB Bancorp’s principal business is to serve as the holding company for its wholly owned banking subsidiaries, Royal Business Bank (“Bank”) and RBB Asset Management Company (“RAM”), collectively referred to herein as “the Company.” RBB Bancorp was formed in January 2011 as a bank holding company and RAM was formed in 2012 to hold and manage problem assets acquired in business combinations. When we refer to “we”, “us”, “our”, or the “Company”, we are referring to RBB Bancorp and its consolidated subsidiaries including the Bank, collectively. When we refer to the “parent company”, “Bancorp”, or the “holding company”, we are referring to RBB Bancorp, the parent company, on a stand-alone basis. At December 31, 2024, the Company had total assets of $4.0 billion, gross consolidated loans of $3.1 billion, total deposits of $3.1 billion and total shareholders' equity of $507.9 million. The Bank provides business-banking and consumer products and services predominantly to the Asian-centric communities through full service branches located in Los Angeles County, Orange County and Ventura County in California, Las Vegas (Nevada), the New York City metropolitan areas, Chicago (Illinois), Edison (New Jersey) and Honolulu (Hawaii). The products and services include commercial and investor real estate loans, business loans and lines of credit, Small Business Administration (“SBA”) 7A and 504 loans, mortgage loans, trade finance and a full range of depository accounts, including specialized services such as remote deposit, E-banking, mobile banking and treasury management services. The Bank acquired the Honolulu, Hawaii branch (the “Hawaii Branch”) from Bank of the Orient (“BOTO”) on January 14, 2022. We operate as a minority depository institution (“MDI”), which is defined by the Federal Deposit Insurance Corporation (“FDIC”) as a federally insured depository institution where 51% or more of the voting stock is owned by minority individuals or a majority of the board of directors is minority and the community that the institution serves is predominantly minority. A MDI is eligible to receive support from the FDIC and other federal regulatory agencies such as training, technical assistance and review of proposed new deposit taking and lending programs, and the adoption of applicable policies and procedures governing such programs. We intend to maintain our MDI designation, as it is expected that at least 51% of our issued and outstanding shares of capital shall remain owned by minority individuals. The MDI designation has been historically beneficial to us, and we continue to use the program for technical assistance. In addition, we have been designated a community development financial institution (“CDFI”). CDFIs are certified by the CDFI Fund at the U.S. Department of the Treasury (“Treasury”), which provide funds to CDFIs through a variety of programs. We have established a CDFI advisory board to assist the Bank in finding organizations to support low-to-moderate income individuals. We operate 24 banking offices in Arcadia, Cerritos, Diamond Bar, Irvine, Los Angeles, Monterey Park, Oxnard, Rowland Heights, San Gabriel, Silver Lake, Torrance, and Westlake Village, California; Las Vegas, Nevada; Manhattan, Brooklyn, Flushing and Elmhurst, New York; the Chinatown and Bridgeport neighborhoods of Chicago, Illinois; Edison, New Jersey; and Honolulu, Hawaii. Our primary source of revenue is providing loans to customers, who are predominately small and middle-market businesses and individuals. We generate our revenue primarily from interest received on loans and, to a lesser extent, from interest received on investment securities. We also derive income from noninterest sources, such as fees received in connection with various lending and deposit services, loan servicing, gain on sales of loans and wealth management services. Our principal expenses include interest expense on deposits and borrowings, and operating expenses, such as salaries and employee benefits, occupancy and equipment, data processing, and income tax expense. We completed six whole bank acquisitions and one branch acquisition from July 2011 through January 2022. All of our acquisitions have been accounted for using the acquisition method of accounting and, accordingly, the operating results of the acquired entities have been included in the consolidated financial statements from their respective acquisition dates.
