Overview
Royal Business Bank is a commercial bank headquartered in Los Angeles, California, serving individuals, small businesses, middle-market companies, municipalities, and other organizations. The bank was established in November 2008 by Louis Chang and initially operated from a single location in Los Angeles. Its early identity was closely associated with the Chinese American community, although its customer base later broadened beyond that community. The bank expanded through a combination of new branch openings and acquisitions. Beginning in 2011, it added locations in San Gabriel, Torrance, and Rowland Heights and acquired First Asian Bank in Las Vegas. In 2015, it completed a larger group of acquisitions involving Ventura County Business Bank, Oxnard; Los Angeles National Bank, Buena Park; and TomatoBank in Alhambra. The reported aggregate consideration for those 2015 transactions was $83.2 million. These deals extended Royal Business Bank's reach across Southern California and Nevada and strengthened its position among community and ethnic-market banking institutions. Royal Business Bank became part of the broader RBB Bancorp platform as that holding company developed its banking franchise. In July 2017, RBB Bancorp entered the Nasdaq market and raised $86 million, providing additional capital for expansion. The bank subsequently broadened its geographic footprint outside the West Coast. In September 2019, it acquired Pacific Global Bank in Chicago for $32.5 million, adding an Illinois presence and another institution with ties to Asian American communities. In May 2021, RBB Bancorp raised $120 million to support further acquisitions, while James Kao was elected chairman of the board. The bank's business model combines relationship-oriented commercial banking with a focus on communities and businesses that may value multilingual service, local market knowledge, and familiarity with cross-border or immigrant-owned enterprises. Its stated customer categories include consumers, small and middle-market businesses, municipalities, and other entities. The available reference material identifies the bank as having branches in California, Nevada, Hawaii, New Jersey, Illinois, and New York. Specific current branch counts, product balances, executive appointments, and financial performance figures are not established by the supplied sources and are therefore not stated here. Royal Business Bank remains a banking brand within RBB Bancorp rather than an independently listed public company. Its development illustrates the consolidation of regional and community banks through acquisitions, combined with geographic expansion into markets containing established Chinese American and broader Asian American populations.
History
Royal Business Bank was founded by Louis Chang in Los Angeles in November 2008. It began as a single-location institution with a focus on serving consumers and businesses in the Chinese American community. The bank's early growth combined organic branch development with acquisitions. From 2011 onward, it opened additional locations in San Gabriel, Torrance, and Rowland Heights, while also acquiring First Asian Bank in Las Vegas. A more substantial phase of consolidation came in 2015, when the bank acquired Ventura County Business Bank in Oxnard, Los Angeles National Bank in Buena Park, and TomatoBank in Alhambra. The reported combined value of these transactions was $83.2 million. The acquisitions expanded Royal Business Bank's presence across Southern California and Nevada and added institutions with established local customer relationships. The bank operated within the RBB Bancorp group, whose public-market development provided capital for continued growth. In July 2017, RBB Bancorp entered the Nasdaq and raised $86 million. This marked an important financing milestone for the group, although Royal Business Bank itself remained a subsidiary rather than a separately listed company. The franchise later expanded into the Midwest. In September 2019, Royal Business Bank acquired Pacific Global Bank in Chicago for $32.5 million. This transaction gave the group an Illinois presence and continued its strategy of acquiring community banks serving Asian American and other commercially active local markets. In May 2021, RBB Bancorp raised a further $120 million to support additional acquisitions. During the same month, James Kao was elected chairman of the board. The bank's stated customer base includes individuals, small businesses, middle-market enterprises, municipalities, and other entities. While its historical positioning centers on the Chinese American community, the institution has also sought customers outside that community. Reference material places its branches in California, Nevada, Hawaii, New Jersey, Illinois, and New York. The supplied sources do not provide a verified current branch count, detailed financial statements, a current executive roster, or a current official website URL. Royal Business Bank is therefore best understood as a regional, acquisition-oriented commercial banking brand within RBB Bancorp, with a presence spanning multiple U.S. metropolitan and community banking markets.
