PART II -- RULES 12b-25(b) AND (c)


If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate)




The reason described in reasonable detail in Part III of this form could not be eliminated without unreasonable effort or expense;


The subject annual report, semi-annual report, transition report on Form 10-K, Form 20-F, Form 11-K, Form N-CEN or Form N-CSR, or portion thereof, will be filed on or before the fifteenth calendar day following the prescribed due date; or the subject quarterly report or transition report on Form 10-Q or subject distribution report on Form 10-D, or portion thereof, will be filed on or before the fifth calendar day following the prescribed due date; and



The accountant's statement or other exhibit required by Rule 12b-25(c) has been attached if applicable.







State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-CEN, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.


RBB Bancorp (the “Company”) is unable to file its Annual Report on Form 10-K for the year ended December 31, 2022 (“Annual Report”) within the prescribed time period without unreasonable effort or expense due to circumstances related to the Company’s first-time adoption of Accounting Standards Update 2016-13 (Topic 326), “Measurement of Credit Losses on Financial Instruments,” commonly referenced as the Current Expected Credit Loss (“CECL”) model. The Company also needs additional time to complete the analysis and evaluate its internal controls over financial reporting related to its adoption of CECL. The Company also needs additional time for Crowe LLP (“Crowe”), its independent registered public accounting firm, to complete certain audit procedures related to the Company’s adoption of CECL, including its evaluation of the effectiveness of the Company’s internal controls over financial reporting. Notwithstanding the foregoing, the Company expects to file its Annual Report no later than March 31, 2023. The Company does not expect any changes to its financial results reported in its press release dated January 23, 2023.


The Company has provided a copy of the foregoing disclosures to Crowe.
