Basis of Presentation	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, 2024 filed by the Company with the SEC. The December 31, 2024 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, 2024 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, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of PCB Bancorp and its wholly owned subsidiary as of March 31, 2025 and December 31, 2024, and for the three months ended March 31, 2025 and 2024. 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.
Use of Estimates in the Preparation of Financial Statements	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 and Recent Accounting Pronouncements Not Yet Adopted	Adopted Accounting Pronouncements During the three months ended March 31, 2025, 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 December 2023, the FASB issued Accounting Standard Update (“ASU”) 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” This ASU requires public business entities to disclose in the rate reconciliation table additional categories of information about federal, state, and foreign income taxes and to provide more details about the reconciling items in some categories if items meet a quantitative threshold. It also requires all entities to disclose income taxes paid, net of refunds, disaggregated by federal, state, and foreign taxes for annual periods and to disaggregate the information by jurisdiction based on a quantitative threshold. This ASU is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted for periods for which financial statements have not yet been issued. This ASU is not expected to have a significant impact on the Company’s Consolidated Financial Statements. 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. The guidance 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.
Fair Value Measurements	ASC 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value including a three-level valuation hierarchy, and expands disclosures about fair value measurements. Fair value is the exchange price that would be received for an asset or paid to transfer a liability (i.e. an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The three-level fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair value are defined as follows: •Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. •Level 2: Significant observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. •Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Fair value is measured on a recurring basis for certain assets and liabilities in which fair value is the primary basis of accounting. Additionally, fair value is used on a non-recurring basis to evaluate certain assets or liabilities for impairment or for disclosure purposes. Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company records securities available-for-sale at fair value on a recurring basis. Certain other assets, such as loans held-for-sale, loans individually evaluated, servicing assets and other real estate owned (“OREO”) are recorded at fair value on a non-recurring basis. Non-recurring fair value measurements typically involve assets that are periodically evaluated for impairment and for which any impairment is recorded in the period in which the re-measurement is performed. The following is a description of valuation methodologies used for assets and liabilities recorded at fair value: Investment securities: The fair values of securities available-for-sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1) or matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2). Management reviews the valuation techniques and assumptions used by the provider and determines that the provider uses widely accepted valuation techniques based on observable market inputs appropriate for the type of security being measured. Securities held-to-maturity are not measured at fair value on a recurring basis. Loans held-for-sale: The Company records SBA loans held-for-sale, residential property loans held-for-sale and certain non-residential real estate loans held-for-sale at the lower of cost or fair value, on an aggregate basis. The Company obtains fair values from a third party independent valuation service provider. Loans held-for-sale accounted for at the lower of cost or fair value are considered to be recognized at fair value when they are recorded at below cost, on an aggregate basis, and are classified as Level 2. Loans individually evaluated: Certain collateral-dependent loans individually evaluated are recognized at fair value when they reflect partial write-downs, through charge-offs or specific reserve allowances, that are based on the current appraised or market-quoted value of the underlying collateral. In some cases, the properties for which market quotes or appraised values have been obtained are located in areas where comparable sales data is limited, outdated, or unavailable. Fair value estimates for collateral-dependent loans individually evaluated are obtained from real estate brokers or other third-party consultants, and are classified as Level 3. Other real estate owned: The Company initially records OREO at fair value at the time of foreclosure. Thereafter, OREO is recorded at the lower of cost or fair value based on their subsequent changes in fair value. The fair value of OREO is generally based on recent real estate appraisals adjusted for estimated selling costs. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments may be significant and result in a Level 3 classification due to the unobservable inputs used for determining fair value. Only OREO with a valuation allowance are considered to be carried at fair value. Servicing Assets: Servicing assets represent the value associated with servicing loans that have been sold. The fair value for servicing assets is determined through discounted cash flow analysis and utilizes discount rates and prepayment speed assumptions as inputs. All of these assumptions require a significant degree of management estimation and judgment. The fair market valuation is performed on a quarterly basis for servicing assets. Servicing assets are accounted for at the lower of cost or market value and considered to be recognized at fair value when they are recorded at below cost and are classified as Level 3.
