Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Nature of Operations PCB Bancorp is a bank holding company whose subsidiary is PCB Bank (the “Bank”), which is a single operating segment. As of March 31, 2026, the Bank operated nine full-service branches in Los Angeles and Orange counties, California, three full-service branches on the East Coast (Bayside, New York; and Englewood Cliffs and Palisades Park, New Jersey), two full-service branches in Texas (Carrollton and Dallas), and one full-service branch in Georgia (Suwanee). The Bank also has loan originators of primarily SBA loans based in the State of Washington. The Bank offers a broad range of loans, deposits, and other products and services predominantly to small and middle market businesses and individuals. Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared pursuant to Article 10 of SEC Regulation S-X and other SEC rules and regulations for reporting on the Quarterly Report on Form 10-Q. Accordingly, certain disclosures required by U.S. generally accepted accounting principles (“GAAP”) are not included herein. These interim statements should be read in conjunction with the audited consolidated financial statements and notes included in the Annual Report on Form 10-K for the year ended December 31, 2025 filed by the Company with the SEC. The December 31, 2025 balance sheet presented herein has been derived from the audited financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC, but does not include all of the disclosures required by GAAP for complete financial statements. In the opinion of management of the Company, the accompanying unaudited interim consolidated financial statements reflect all of the adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the consolidated financial condition and consolidated results of operations as of the dates and for the periods presented. Certain reclassifications have been made in the prior period financial statements to conform to the current period presentation. The results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results that may be expected for the year ending December 31, 2026. Principles of Consolidation The consolidated financial statements include the accounts of PCB Bancorp and its wholly owned subsidiary as of March 31, 2026 and December 31, 2025, and for the three months ended March 31, 2026 and 2025. Significant inter-company accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its wholly owned subsidiary. Significant Accounting Policies The accounting and reporting policies of the Company are based upon GAAP and conform to predominant practices within the banking industry. Other than as disclosed below, the Company has not made any significant changes in its critical accounting policies from those disclosed in its Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC. Use of Estimates in the Preparation of Financial Statements The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates are subject to change and such change could have a material effect on the consolidated financial statements. Actual results may differ from those estimates. Adopted Accounting Pronouncements During the three months ended March 31, 2026, there were no significant accounting pronouncements applicable to the Company that were adopted or became effective. Recent Accounting Pronouncements Not Yet Adopted The following recently issued accounting pronouncement applicable to the Company has not yet been adopted: In November 2024, the FASB issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” This ASU requires disaggregated disclosure of income statement expenses for public business entities. This ASU requires new financial statement disclosures in tabular format, disaggregating information about prescribed categories underlying any relevant income statement expense caption. The prescribed categories include, among other things, employee compensation, depreciation, and intangible asset amortization. Additionally, entities must disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. This ASU is effective for annual reporting periods beginning after December 15, 2026, and for interim reporting periods within fiscal years beginning after December 15, 2027. This ASU can be applied prospectively with an option for retrospective application and early adoption is permitted. This ASU is not expected to have a significant impact on the Company’s Consolidated Financial Statements. In November 2025, the FASB issued ASU 2025-08, “Financial Instruments - Credit Losses (Topic 326): Purchased Loans.” This ASU expands the scope of the “gross-up” method, formerly applicable only to purchased credit-deteriorated (“PCD”) assets, to include acquired non-PCD loans that meet certain criteria, now referred to as “purchased seasoned loans” (“PSLs”). Under this model, an allowance for expected credit losses is recognized at acquisition, offsetting the loan’s amortized cost basis, thereby eliminating the day-one credit-loss expense previously required for non-PCD assets. PSLs are defined as non-PCD loans acquired either (i) through a business combination, or (ii) purchased more than 90 days after origination when the acquirer was not involved in origination. This ASU will be effective for interim and annual reporting periods beginning after December 15, 2027 and early adoption is permitted. This ASU is not expected to have a significant impact on the Company’s Consolidated Financial Statements. In December 2025, the FASB issued ASU 2025-11, “Interim Reporting (Topic 270): Narrow-Scope Improvements.” This ASU clarifies and enhances guidance under ASC 270 on interim financial reporting by (i) clarifying the scope of ASC 270 such that it now explicitly applies only to entities that issue complete interim financial statements and related notes under U.S. GAAP, (ii) establishing clear guidance on the form of interim statements and notes, incorporating a comprehensive list of required interim disclosures drawn from across the ASC, and (iii) introducing a requirement to disclose material events and changes occurring after the end of the last annual period that could impact interim results. This ASU is effective for interim reporting periods within fiscal years beginning after December 15, 2027 and early adoption is permitted. Aside from complying with the new disclosure requirements, this ASU is not expected to have a significant impact on the Company’s Consolidated Financial Statements.
