Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies	Description of Business and Summary of Significant Accounting Policies Nature of operations - Coastal Financial Corporation (“Corporation” or “Company”) is a registered bank holding company whose wholly owned subsidiaries are Coastal Community Bank (“Bank”) and Arlington Olympic LLC. The Company is a Washington state corporation that was organized in 2003. The Bank was incorporated and commenced operations in 1997 and is a Washington state-chartered commercial bank and Federal Reserve System (“Federal Reserve”) state member bank. Arlington Olympic LLC was formed in 2021 and owns the Arlington branch site, which the Bank leases from the LLC. The Company operates through the Bank and is headquartered in Everett, Washington, which by population is the largest city in, and the county seat of, Snohomish County. The Company’s business is conducted through three reportable segments: The community bank, CCBX and treasury & administration. The community bank offers a full range of banking services to small and medium-sized businesses, professionals, and individuals throughout the greater Puget Sound region through its 14 branches in Snohomish, Island and King Counties, the Internet, and its mobile banking application. The CCBX segment provides Banking as a Service (“BaaS”) that allows our broker dealers and digital financial service partners to offer their customers banking services. Through CCBX’s partners the Company is able to offer banking services and products across the nation. The treasury & administration segment includes treasury management, overall administration and all other aspects of the Company. The Bank’s deposits are insured in whole or in part by the Federal Deposit Insurance Corporation (“FDIC”). The community bank’s loans and deposits are primarily within the greater Puget Sound region, while CCBX loans and deposits are dependent upon the partner’s market. The Bank’s primary funding source is deposits from customers. The Bank is subject to regulation and supervision by the Board of Governors of the Federal Reserve System and the Washington State Department of Financial Institutions Division of Banks. The Federal Reserve also has regulatory and supervisory authority over the Company. Financial statement presentation - The accompanying audited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for reporting requirements and practices within the banking industry. Amounts presented in the consolidated financial statements and footnote tables are rounded and presented in thousands of dollars except per-share amounts, which are presented in dollars. In the narrative footnote discussion, amounts are rounded to thousands and presented in dollars. In management’s opinion, all accounting adjustments necessary to accurately reflect the financial position and results of operations on the accompanying consolidated financial statements have been made. These adjustments include normal and recurring accruals considered necessary for a fair and accurate presentation. Principles of consolidation - The consolidated financial statements include the accounts of the Company, the Bank and the LLC. All significant intercompany accounts have been eliminated in consolidation. Estimates - The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management believes that its critical accounting estimates include determining the allowance for credit losses, the fair value of the Company’s financial instruments, and the valuation of deferred tax assets, financial instruments, and other fair value measurements. Actual results could differ significantly from those estimates. Subsequent Events - The Company has evaluated events and transactions subsequent to December 31, 2023 for potential recognition or disclosure . Cash equivalents and cash flows - For purposes of reporting cash flows, cash and cash equivalents include cash on hand and in banks and interest-bearing deposits. All have original maturities of three months or less. CDs with other financial institutions, federal funds sold and cash flows from loans and deposits are reported as net increases or decreases under cash flows from investing activities or from financing activities. The Company maintains its cash in depository institution accounts, which, at times, may exceed federally insured limits. The Company monitors these institutions and has not experienced any losses in such accounts. Investment securities - Debt securities that management has the ability and intent to hold to maturity are classified as held-to-maturity and carried at amortized cost. The amortization of premiums and accretion of discounts are recognized in interest income using the interest method or methods approximating the interest method over the period to maturity. Debt securities not classified as held-to-maturity are classified as available-for-sale. Such securities may be sold to facilitate the Company’s asset/liability management strategies and in response to changes in interest rates and similar forces. Securities available-for-sale are carried at fair value with unrealized gains and losses reported in other comprehensive income. Realized gains (losses) on securities available-for-sale are included in noninterest income and, when applicable, are reported as a reclassification adjustment in other comprehensive income. Gains and losses on sales of securities are recorded on the trade date and are determined on the specific-identification method. For available-for-sale debt securities, if fair value is below amortized cost, the security is considered impaired. When the Company does not intend to sell the debt security, and it is more likely than not the Company will not have to sell the security before recovery of its cost basis, then the Company assesses the security for potential expected credit losses. Impairment related to a credit loss is measured using the discounted cash flow method. Credit loss recognition is limited to the fair value of the security. The impairment is recognized by establishing an ACL through provision for credit losses. Impairment related to noncredit factors is recognized in accumulated other comprehensive income, net of applicable taxes. The Company evaluates AFS security impairment on a quarterly basis. For held-to-maturity debt securities, expected losses are evaluated and calculated on a collective basis for those securities which share risk characteristics. The Company aggregates similar securities and reports the security portfolio segments based on shared risk characteristics. The only segment included in the held-to-maturity portfolio are U.S. Agency Residential Mortgage Backed Securities which have an expected zero credit loss and were purchased for CRA purposes. Other investments - Other investments on the balance sheet consists of direct equity investments in stock of the Federal Home Loan Bank of Des Moines (“FHLB”), the Federal Reserve Bank of San Francisco (“FRB”), Pacific Coast Banker’s Bancshares, as well as investments in bank technology funds. As a Federal Reserve member bank, the Bank is required to own stock in the FRB in an amount based on the Bank’s capital. The recorded amount of the FRB stock equals its fair value because the shares can only be redeemed by the FRB at their par value. The Bank’s investment in FRB stock was $4.8 million and $4.3 million at December 31, 2023 and 2022, respectively. The Bank, as a member of the FHLB, is required to maintain an investment in capital stock of FHLB in an amount equal to 4.5% of advances outstanding, plus 0.06% of total assets from the prior fiscal year end. The recorded amount of FHLB stock equals its fair value because the shares can only be redeemed by FHLB at the $1 per share par value. The investment in FHLB stock was $1.9 million and $3.2 million at December 31, 2023 and 2022, respectively. The investment in Pacific Coast Banker’s Bancshares (“PCBB”) stock consists of an equity security. This investment is carried at its cost of $100,000 at December 31, 2023 and 2022, which approximates its fair value. The Company has the following equity investments which do not have a readily determinable fair value and are held at cost minus impairment if any, plus or minus observable price changes in orderly transactions for an identical or similar investment of the same issuer. This method will be applied until the investments do not qualify for the measurement election (e.g., if the investment has a readily determinable fair value). The Company will reassess at each reporting period whether the equity investments without a readily determinable fair value qualifies to be measured at cost minus impairment. These equity investments without a readily determined fair value include: • The Company has a $2.2 million equity interest in a specialized bank technology company as of December 31, 2023 and December 31, 2022 . • The Company has a $350,000 equity interest in a technology company as of the years ended December 31, 2023 and December 31, 2022. • The Company contributed $50,000 to a technology company during the year ended December 31, 2023, there was no equity ownership as of December 31, 2022. The following table shows the activity in equity investments without a readily determinable fair value for the dates shown: For the Twelve Months Ended (dollars in thousands) 2023 2022 2021 Carrying value, beginning of period $ 2,572 $ 2,322 850 Purchases 50 350 — Observable price change — (100) 1,472 Carrying value, end of period $ 2,622 $ 2,572 $ 2,322 The Company has invested in funds that are accelerating technology for adoption by banks. These equity investments are held at fair value, as reported by the funds. During the year ended December 31, 2023, the Company contributed $74,500 with investment funds designed to help accelerate technology adoption at banks, and recognized net gains of $278,000, resulting in an equity interest of $809,000 at December 31, 2023. The Company has committed up to $653,000 in capital for these equity funds. One firm decided to wind down their technology fund and their fund balance decreased $176,000 in 2023, leaving $22,000 in that fund as of December 31, 2023. The following table shows the activity in equity fund investments held at fair value for the dates shown: For the Twelve Months Ended (dollars in thousands) 2023 2022 2021 Carrying value, beginning of period $ 456 $ 160 — Purchases/capital calls/capital returns, net 75 349 163 Net change recognized in earnings 278 (53) (3) Carrying value, end of period $ 809 $ 456 $ 160 Loans and allowance for credit losses – Loans are stated at the principal amount outstanding less the allowance for credit losses and net of any deferred fees or costs on originated loans, and unamortized premiums or discounts on purchased loans. Loan fees and certain direct loan origination costs are deferred, and the net fee or cost is recognized as an adjustment to interest income using the level yield methodology and a method that approximates the level yield methodology. Interest income on loans is recognized based upon the principal amounts outstanding. The accrual of interest on community bank loans is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due or when they are 90 days past due as to either principal or interest, unless they are well secured and in the process of collection. When interest accrual is discontinued, all unpaid accrued interest is reversed against current income. If management determines that the ultimate collectability of principal or interest is in doubt, cash receipts on nonaccrual loans are applied to reduce the principal balance on a cash-basis method, until the loans qualify for return to accrual status or principal is paid in full. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current, borrower has demonstrated ability to make regular payments, generally a period of at least six months, and future payments are reasonably assured. For installment/closed-end, and revolving/open-end consumer loans originated through CCBX lending partners loans will accrue interest until 120 and 180 days past due, respectively, which is consistent with regulatory guidelines for consumer loans of this nature, and an allowance is recorded through provision expense for these expected losses. For installment/closed-end and revolving/open-end consumer loans originated through CCBX lending partners with balances outstanding beyond 120 days and 180 days, respectively, principal and capitalized interest outstanding is charged off against the allowance and accrued interest outstanding is reversed against interest income. The allowance for credit losses is comprised of amounts charged against income in the form of the provision for credit losses, less charged-off loans, net of recoveries. When available information confirms that specific loans or portions thereof are uncollectible, identified amounts are charged against the allowance for credit losses. The existence of some or all of the following criteria will generally confirm that a loss has been incurred: (1) the loan is significantly delinquent and the borrower has not demonstrated the ability or intent to bring the loan current; (2) the Company has no recourse to the borrower or if it does, the borrower has insufficient assets to pay the debt; (3) the estimated fair value of the loan collateral is significantly below the current loan balance; and (4) there is little or no near-term prospect for improvement. Subsequent recoveries, if any, are credited to the allowance for credit losses. The allowance for credit losses ("ACL") is an estimate of the expected credit losses on financial assets measured at amortized cost. The ACL is evaluated and calculated on a collective basis for those loans which share similar risk characteristics. At each reporting period, the Company evaluates whether the loans in a pool continue to exhibit similar risk characteristics as the other loans in the pool and whether it needs to evaluate the allowance on an individual basis. The Company must estimate expected credit losses over the loans’ contractual terms, adjusted for expected prepayments. In estimating the life of the loan, the Company cannot extend the contractual term of the loan for expected extensions, renewals, and modifications, unless the extension or renewal options are included in the contract at the reporting date and are not unconditionally cancellable by the Company. Because expected credit losses are estimated over the contractual life adjusted for estimated prepayments, determination of the life of the loan may significantly affect the ACL. The Company has chosen to segment its portfolio consistent with the manner in which it manages the risk of the type of credit. • Community Bank Portfolio: The ACL calculation is derived from loan segments utilizing loan level information and relevant available information from internal and external sources related to past events and current conditions. In addition, the Company incorporates a reasonable and supportable forecast. • CCBX Portfolio: The Bank calculates the ACL on loans on an aggregate basis based on each partner and product level, segmenting the risk inherent in the CCBX portfolio based on qualitative and quantitative trends in the portfolio. Also included in the ACL are qualitative reserves to cover losses that are expected, but in the Company’s assessment may not be adequately represented in the quantitative method. For example, factors that the Company considers include environmental business conditions, borrower’s financial condition, credit rating and the volume and severity of past due loans and non-accrual loans. Based on this analysis, the Company records a provision for credit losses to maintain the allowance at appropriate levels. Determining the amount of the allowance is considered a critical accounting estimate, as it requires significant judgment and the use of subjective measurements, including management’s assessment of overall portfolio quality. The Company maintains the allowance at an amount the Company believes is sufficient to provide for estimated losses expected to occur in the Company’s loan portfolio at each balance sheet date, and fluctuations in the provision for credit losses may result from management’s assessment of the adequacy of the allowance. Changes in these estimates and assumptions are possible and may have a material impact on the Company’s allowance, and therefore the Company’s financial position, liquidity or results of operations. The Company has elected to exclude accrued interest receivable from the amortized cost basis in its ACL calculation as accrued interest is written off in a timely manner when deemed uncollectible. For more information and discussion related to the allowance for credit losses on loans, see “Note 4 - Loans and Allowance for Credit Losses” in the Consolidated Financial Statements. In addition to the ACL on loans held for investment, CECL requires a balance sheet liability for expected losses on unfunded commitments, which is recognized if both the following conditions are met: (1) the Company has a present contractual obligation to extend credit; and (2) the obligation is not unconditionally cancellable by the Company. Loan commitments may have a funded and unfunded portion, of which the liability for unfunded commitments is derived based upon the commitments to extend credit to a borrower. The expected credit losses for funded portions are reported in the previously discussed ACL. The unfunded commitments that are not unconditionally cancelable by the Company are allowed for using the same loss rate as the funded commitment applied against the estimated utilization of these commitments and the probability of funding. Loans held-for-sale - During the year ended December 31, 2023, the Company transferred $599.9 million in CCBX loans receivable to loans held for sale. The loans sold to the originating partners are in accordance with partner agreements and are primarily sold for credit and concentration management. As of December 31, 2023 and 2022 there were no loans held for sale. Community bank loans held-for-sale consist of the guaranteed portion of SBA loans and USDA loans the Company intends to sell after origination and are reflected at the lower of aggregate cost or fair value. Loans are generally sold with servicing of the sold portion retained by the Company when the sale of the loan occurs, the premium received is combined with the estimated present value of future cash flows on the related servicing asset and recorded as a gain on sale of loans in noninterest income. There were no loans held for sale at December 31, 2023 and 2022. Loan sales recognition - The Company recognizes a sale on loans if the transferred portion (or portions) and any portion that continues to be held by the transferor are participating interests. Participating interest is defined as a portion of a financial asset that (a) conveys proportionate ownership rights with equal priority to each participating interest holder, (b) involves no recourse (other than standard representations and warranties), and (c) does not entitle any participating interest holder to receive cash before any other participating interest holder. The transfer of the participating interest (or participating interests) must also meet the conditions for surrender of control. To determine the gain or loss on sale of loans, the Company’s investment in the loan is allocated among the retained portion of the loan, the servicing retained, and the sold portion of the loan, based on the relative fair market value of each portion. The gain or loss on the sold portion of the loan is based on the difference between the sale proceeds and the allocated investment in the sold portion of the loan. A discount is recorded against the carrying value of the retained portion of the loan to offset the decrease in the fair value allocation of said retained portion. The Company retains the servicing on the sold guaranteed portion of SBA and USDA loans. The Company receives a fee for servicing the loan. The Company also retains the servicing on the sold guaranteed portion of Main Street Lending Program (“MSLP”) loans. The net deferred fee on the sold portion of the loan is recognized when sold. The Company does not retain the servicing on sold CCBX loans. Reserve for unfunded commitments - The Company maintains a balance sheet liability for expected losses on unfunded commitments, which is recognized if both the following conditions are met: (1) the Company has a present contractual obligation to extend credit; and (2) the obligation is not unconditionally cancellable by the Company. Loan commitments may have a funded and unfunded portion, of which the liability for unfunded commitments is derived based upon the commitments to extend credit to a borrower. An estimate of expected credit losses is not established for unfunded portions of loan commitment that are unconditionally cancellable by the Company. The expected credit losses for funded portions are reported in the previously discussed ACL. The Company segments its unfunded commitment portfolio consistent with the ACL calculation, separating between unfunded lines and commitments to originate. The Company incorporates the probability of funding (i.e. estimate of utilization) for each segment and then utilizes the ACL loss rates for each segment on an aggregate basis to calculate the allowance for unfunded commitments. The reserve for unfunded commitments was $582,000 and $974,000 as of December 31, 2023 and 2022, respectively, and includes a reserve for community bank loans and CCBX loans. Premises and equipment - Premises and equipment are stated at cost less accumulated depreciation. Depreciation expense is computed using the straight-line method based upon the estimated useful lives of the assets. Asset lives range from three . Leasehold improvements are amortized over the expected term of the lease including options to extend which are reasonably certain to be exercised or the estimated useful life of the improvement, whichever is less. The Company capitalizes internal and external costs related to internal-use software during the application development stage, including consulting costs and compensation expenses related to employees who devote time to the development of the projects. The Company records capitalized software development costs in premises and equipment in the Consolidated Balance Sheets. Costs incurred in preliminary stages of development activities and post implementation activities are expensed in the period incurred. The Company may also capitalize costs related to specific upgrades and enhancements when it is probable the expenditures will result in additional functionality. Once the software is substantially complete and ready for its intended use, capitalization ceases and the asset is amortized straight line over its estimated useful life, which is typically three years. Maintenance and repairs are charged to operating expenses. Renewals and betterments are added to the asset accounts and depreciated over the periods benefited. Depreciable assets sold or retired are removed from the asset and related accumulated depreciation accounts and any gain or loss is reflected in the income statement. These assets are reviewed for impairment when events indicate their carrying value may not be recoverable. If management determines impairment exists, the asset is reduced with an offsetting charge to the income statement. Transfers of financial assets - Transfers of an entire financial asset are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when: (1) a group of financial assets or a participating interest in an entire financial asset has been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Other real estate owned and repossessed assets - Other real estate owned and repossessed assets are foreclosed property held pending disposition and are initially recorded at fair value less estimated selling costs when acquired, establishing a new cost basis. At foreclosure, if the fair value of the asset acquired less estimated selling costs is less than the Company’s recorded investment in the related loan, a write-down is recognized through a charge to the allowance for credit losses. Costs of significant property improvements that increase the value of the property are capitalized, whereas costs relating to holding the property are expensed. Valuations are periodically performed by management, and a valuation allowance is established for subsequent declines, which are recorded as a charge to income, if necessary, to reduce the carrying value of the property to its fair value less estimated selling costs. Leases - The Company accounts for its leases in accordance with ASC 842 - Leases . Most leases are recognized on the balance sheet by recording a right-of-use asset and lease liability for each lease. The right-of-use asset represents the right to use the asset under lease for the lease term, and the lease liability represents the contractual obligation to make lease payments. The right-of-use asset is tested for impairment whenever events or changes in circumstances indicate the carrying amount may not be recoverable. As a lessee, the Company enters into operating leases for certain Bank branches. The right-of-use assets and lease liabilities are initially recognized based on the net present value of the remaining lease payments which include renewal options where the Company is reasonably certain they will be exercised. The net present value is determined using the incremental collateralized borrowing rate at commencement date. The right-of-use asset is measured at the amount of the lease liability adjusted for any prepaid rent, lease incentives and initial direct costs incurred. The right-of-use asset and lease liability is amortized over the individual lease terms. Lease expense for lease payments is recognized on a straight-line basis over the lease term. For additional information regarding leases, see Note 6. Income taxes - The Company and the Bank file a consolidated federal income tax return and state tax returns as applicable. Deferred income taxes result from temporary differences between the tax basis of assets and liabilities, and their reported amounts in the financial statements. Deferred taxes are temporary differences that will be recognized in future periods. As changes in tax law or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. Federal taxes are paid by the Bank to the Company based on the separate taxable income of the Bank. The Company and Bank maintain their records on the accrual basis of accounting for financial reporting and for income tax reporting purposes. As of December 31, 2023 and 2022, the Company had no material unrecognized income tax benefits. The Company recognizes interest accrued and penalties related to unrecognized tax benefits in other noninterest expense. There were no interest and penalties assessed on income taxes during 2023 or 2022. Stock-based compensation - Compensation expense is recognized for stock options and restricted stock, based on the fair value of these awards at the grant date. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the grant date is used for restricted stock awards and restricted stock units and is determined on the basis of objective criteria including trade data. Compensation cost is recognized over the requisite service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. Earnings per common share - Earnings per common share (“EPS”) is computed under the two-class method. Pursuant to the two-class method, nonvested stock based payment awards that contain non-forfeitable rights to dividends or dividend equivalents are participating securities and are included in the computation of EPS. The two-class method is an earnings allocation formula that determines earnings per share for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. Application of the two-class method resulted in the equivalent earnings per share to the treasury method. Basic earnings per common share is computed by dividing net earnings allocated to common shareholders by the weighted-average number of common shares outstanding during the applicable period, excluding outstanding participating securities. Diluted earnings per common share is computed using the weighted-average number of shares determined for the basic earnings per common share computation plus the dilutive effect of stock using the treasury stock method. Stock options that are anti-dilutive are not included in the calculation of diluted EPS. Comprehensive income - Accounting principles generally require that recognized revenue, expenses, gains, and losses be included in net income. Certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale investments, are reported as a separate component of the shareholders’ equity section of the balance sheets. Accumulated other comprehensive income consists of only one component: unrealized gains or losses on investment securities available-for-sale. Business Segments – For financial reporting purposes, the Company has three segments: The community bank, CCBX and treasury & administration. The community bank business is that of a traditional banking institution, gathering deposits and originating loans for portfolio in its market areas. The community bank offers a wide variety of deposit products to their customers. Lending activities include the origination of real estate, commercial and industrial, and consumer loans. Interest income on loans is the Company’s primary source of revenue, and is supplemented by interest income from investment securities, deposit service charges, and other service provided activities. The CCBX segment provides banking as a service (“BaaS”) that allows our broker-dealer and digital financial service partners to offer their customers banking services. The CCBX segment has 21 partners as of December 31, 2023. The treasury & administration segment includes treasury management, overall administration and all other aspects of the Company. The performance of the Company is reviewed and monitored by the Company’s executive management on a daily basis and the Board of Directors reviews and monitors the performance of the Company at minimum, on a monthly basis. For additional information regarding the business segments, see Note 21. Advertising costs - Advertising costs are expensed as incurred or over the period of the campaign/promotion. Advertising costs in the amount of $517,000 and $351,000 were expensed during the year ended December 31, 2023 and 2022, respectively . Reclassifications - Certain amounts reported in prior years' consolidated financial statements may have been reclassified to conform to the current presentation with no effect on shareholders’ equity or net income.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent accounting standards	Recent accounting standards Implementation of ASU 2016-13 - On January 1, 2023, the Company adopted ASU 2016-13, Financial Instruments — Credit Losses (Topic 326) : Measurement of Credit Losses on Financial Instruments, which replaces the incurred loss with an expected loss methodology that is referred to as the current expected credit loss ("CECL") methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized costs, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in certain leases. In addition, ASC 326 made changes to the accounting for available-for-sale debt securities. One such change is to require increases or decreases in credit losses be presented as an allowance rather than as a write-down on available-for-sale debt securities management does not intend to sell or believe it is more likely than not the Company will be required to sell the security before recovery of the amortized cost basis. The Company adopted ASC 326 using the modified retrospective method. Results for the reporting periods beginning after January 1, 2023 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The day one CECL adjustment for community bank loans included a reduction of $310,000 to the community bank allowance in the first quarter of 2023 and a reduction of $340,000 related to the community bank unfunded commitment reserve in the first quarter of 2023. This was offset by an increase to the CCBX allowance for $4.2 million in the same period. There was a CECL day one increase to the indemnification asset in the amount of $4.5 million due to the mirror image approach related to the credit enhancement for CCBX loans. Net, the day one impact for the Bank’s transition to CECL was an increase of $954,000 in the first quarter of 2023, which included an income tax impact of $220,000, resulting in an increase to retained earnings of $734,000, net of income taxes. Management has separately evaluated its held-to-maturity investment securities and determined that no loss reserves were required. The following table illustrates the impact of ASU 2016-13: January 1, 2023 As reported Pre-ASC 326 Impact of Assets: Allowance for credit losses $ 77,881 $ 74,029 $ 3,852 CCBX credit enhancement asset 57,842 53,377 4,465 Deferred tax asset 18,238 18,458 (220) Liabilities: Unfunded commitment reserve 634 974 (340) Shareholders' Equity: Retained earnings 120,732 119,998 734 Implementation of ASU 2022-02 - On January 1, 2023, the Company adopted ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings ("TDR") and Vintage Disclosures. The ASU eliminated the accounting guidance for TDR loans by creditors while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, the ASU requires public business entities to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases. This ASU was effective upon adoption of ASU 2016-13 and was applied on a prospective basis. See “ Note 4 - Loans and Allowance for Credit Losses (“ACL”)” for more information on loans that were modified to borrowers experiencing financial difficulty during the twelve months ended months ended December 31, 2023.

During the year ended December 31, 2023, a total of 16 U.S. Agency mortgage backed securities were purchased for a total of $50.2 million, for CRA purposes during the year ended December 31, 2023. There were no sales of investments during the year ended December 31, 2023 or December 31, 2022. At December 31, 2023 and December 31, 2022, there were nine and six securities, respectively, in an unrealized loss position. The following table shows the investments’ gross unrealized losses and fair values, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position for which an allowance for credit losses has not been recorded: Less Than 12 Months 12 Months or Greater Total Fair Gross Fair Gross Fair Gross (dollars in thousands) December 31, 2023 Available-for-sale U.S. Treasury securities $ — $ — $ 99,461 $ 535 $ 99,461 $ 535 U.S. Agency collateralized mortgage obligations — — 43 2 43 2 Total available-for-sale securities — — 99,504 537 99,504 537 Held-to-maturity U.S. Agency residential mortgage-backed securities 11,236 173 882 113 12,118 286 Total investment securities $ 11,236 $ 173 $ 100,386 $ 650 $ 111,622 $ 823 Management has evaluated the above securities and does not believe that any individual unrealized loss as of December 31, 2023, will be recognized into income. Unrealized losses have not been recognized into income because management does not intend to sell and does not expect it will be required to sell the investments. The decline is largely due to changes in market conditions and interest rates, rather than credit quality. The fair value is expected to recover as the underlying securities in the portfolio approach maturity date and market conditions improve. Management believes there is a high probability of collecting all contractual amounts due, because the majority of the securities in the portfolio are backed by government agencies or government sponsored enterprises. However, a recovery in value may not occur for some time, if at all, and may be delayed for greater than the one year time horizon or perhaps even until maturity. Based on management's analysis no allowance for credit losses was required on these securities.

Receivables [Abstract]
Loans and Allowance for Loan Losses (“ACL")	Loans and Allowance for Credit Losses (“ACL”) During the year ended December 31, 2023, $599.9 million in CCBX loans were transferred to loans held for sale, with $599.9 million in loans sold. A portion of these loans were sold at par and a portion were sold with a gain on sale of $253,000. Pricing is dependent upon the agreement with the partner. The Company sells CCBX loans to manage loan portfolio size by partner and by loan category. Partner loan limits are established and documented in the relevant partner agreement. As of December 31, 2023 and December 31, 2022, there were no loans held for sale. The Company adopted the CECL methodology for measuring credit losses as of January 1, 2023. All disclosures as of and for the twelve months ended months ended December 31, 2023 are presented in accordance with Topic 326. The Company did not recast comparative financial periods and has presented those disclosures under previously applicable GAAP.

The balance of MSLP loans participated and serviced for others totaled $53.4 million and $58.0 million at December 31, 2023 and December 31, 2022, respectively, with $2.8 million and $3.1 million outstanding and included in commercial and industrial loans as of December 31, 2023 and December 31, 2022, respectively. The Company, through the community bank, at times, purchases individual loans at fair value as of the acquisition date. The Company held purchased loans with remaining balances totaled $8.1 million and $9.6 million as of December 31, 2023 and December 31, 2022, respectively. Unamortized premiums totaled $154,000 and $167,000 as of December 31, 2023 and December 31, 2022, respectively, and are amortized into interest income over the life of the loans. These loans are included in the applicable loan category depending upon the collateral and purpose of the individual loan. The Company, through the community bank, has purchased participation loans with remaining balances totaling $53.5 million and $63.9 million as of December 31, 2023 and December 31, 2022, respectively. These loans are included in the applicable loan category depending upon the collateral and purpose of the individual loan. The Company, through the community bank, purchased loans from CCBX partners, at par, through agreements with those CCBX partners, and those loans had a remaining balance of $46.5 million as of December 31, 2023 and $157.4 million as of December 31, 2022. As of December 31, 2023, $40.2 million is included in consumer and other loans and $6.3 million is included in commercial and industrial loans, compared to $146.1 million in consumer and other loans and $11.3 million in commercial and industrial loans as of December 31, 2022. The following is a summary of the Company’s loan portfolio segments: Commercial and industrial loans - Commercial and industrial loans are secured by business assets including inventory, receivables and machinery and equipment of businesses located generally in the Company’s primary market area and capital calls on venture and investment funds. Also included in commercial and industrial loans are $54.3 million in unsecured loans originated through CCBX partners as of December 31, 2023, compared to $14.9 million as of December 31, 2022. Loan types in this segment include PPP loans, revolving lines of credit, term loans, and loans secured by liquid collateral such as cash deposits or marketable securities. In addition, included in commercial and industrial loans are loans to other financial institutions. Additionally, the Company issues letters of credit on behalf of its customers. Risk arises primarily due to the difference between expected and actual cash flows of the borrowers. In addition, the recoverability of the Company’s investment in these loans is also dependent on other factors primarily dictated by the type of collateral securing these loans. The fair value of the collateral securing these loans may fluctuate as market conditions change. In the case of loans secured by accounts receivable, the recovery of the Company’s investment is dependent upon the borrower’s ability to collect amounts due from its customers. For the year ended December 31, 2023, $87.5 million in CCBX capital call lines are included in commercial and industrial loans compared to $146.0 million at December 31, 2022. Capital call lines are provided to venture capital firms. These loans are secured by the capital call rights and are individually underwritten to the Bank’s credit standards and the underwriting is reviewed by the Bank on every line/loan. Construction, land and land development loans – The Company originates loans for the construction of 1-4 family, multifamily, and CRE properties in the Company’s market area. Construction loans are considered to have higher risks due to construction completion and timing risk, the ultimate repayment being sensitive to interest rate changes, government regulation of real property and the availability of long-term financing. Additionally, economic conditions may impact the Company’s ability to recover its investment in construction loans, as adverse economic conditions may negatively impact the real estate market, which could affect the borrower’s ability to complete and sell the project. Additionally, the fair value of the underlying collateral may fluctuate as market conditions change. The Company occasionally originates land loans for the purpose of facilitating the ultimate construction of a home or commercial building. The primary risks include the borrower’s ability to pay and the inability of the Company to recover its investment due to a material decline in the fair value of the underlying collateral. Residential real estate - Residential real estate includes various types of loans for which the Company holds real property as collateral. Included in this segment are multi-family loans, first lien single family loans, which the Company occasionally purchases to diversify its loan portfolio, home equity lines of credit and rental portfolios secured by one-to-four family homes. The primary risks of residential real estate loans include the borrower’s inability to pay, material decreases in the value of the collateral, and significant increases in interest rates which may make the loan unprofitable. As of December 31, 2023, $238.0 million in loans originated through CCBX partners are included in residential real estate loans, compared to $244.6 million at December 31, 2022. These home equity lines of credit are secured by residential real estate and are accessed by using a credit card. Home equity lines of credit are classified as residential real estate per regulatory guidelines. Commercial real estate (includes owner occupied and nonowner occupied) - Commercial real estate loans include various types of loans for which the Company holds real property as collateral. We make commercial mortgage loans collateralized by owner-occupied and non-owner-occupied real estate, as well as multi-family residential loans. The primary risks of commercial real estate loans include the borrower’s inability to pay, material decreases in the value of the collateralized real estate and significant increases in interest rates, which may make the real estate loan unprofitable. Commercial real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. Consumer and other loans – The community bank originates a limited number of consumer loans, generally for banking customers only, which consist primarily of lines of credit, saving account secured loans, and auto loans. CCBX originates consumer loans including credit cards, consumer term loans and secured and unsecured lines of credit. This loan category also includes overdrafts. Repayment of these loans is dependent on the borrower’s ability to pay and the fair value of the underlying collateral. As of December 31, 2023 $816.4 million in CCBX loans are included in consumer and other loans, compared to $607.0 million at December 31, 2022. Past due and Nonaccrual Loans The following table illustrates an age analysis of past due loans as of the dates indicated: 30-89 90 Days Total Current Total 90 Days or (dollars in thousands; unaudited) December 31, 2023 Community Bank Commercial and industrial $ — $ — $ — $ 149,502 $ 149,502 $ — Real estate loans: Construction, land and land development — — — 157,100 157,100 — Residential real estate 44 — 44 225,347 225,391 — Commercial real estate — 7,145 7,145 1,296,388 1,303,533 — Consumer and other loans 2 — 2 1,626 1,628 — Total community bank $ 46 $ 7,145 $ 7,191 $ 1,829,963 $ 1,837,154 $ — CCBX Commercial and industrial loans: Capital call lines $ — $ — $ — $ 87,494 $ 87,494 $ — All other commercial & industrial loans 3,433 2,086 5,519 48,779 54,298 2,086 Real estate loans: Residential real 3,198 1,115 4,313 $ 233,722 $ 238,035 1,115 Consumer and other loans: Credit cards 28,383 34,835 63,218 $ 442,619 $ 505,837 34,835 Other consumer and 29,645 8,488 38,133 272,441 310,574 8,488 Total CCBX $ 64,659 $ 46,524 $ 111,183 $ 1,085,055 $ 1,196,238 $ 46,524 Total Consolidated $ 64,705 $ 53,669 $ 118,374 $ 2,915,018 3,033,392 $ 46,524 Less net deferred origination fees and premiums (7,300) Loans receivable $ 3,026,092 Consolidated 30-89 90 Days Total Current Total 90 Days or (dollars in thousands) December 31, 2022 Commercial and industrial loans $ 393 $ 486 $ 879 $ 311,749 $ 312,628 $ 404 Real estate loans: Construction, land and land development — 66 66 213,989 214,055 — Residential real estate 1,016 876 1,892 447,265 449,157 876 Commercial real estate 95 6,901 6,996 1,041,756 1,048,752 — Consumer and other loans 37,932 24,815 62,747 546,024 608,771 24,815 $ 39,436 $ 33,144 $ 72,580 $ 2,560,783 $ 2,633,363 $ 26,095 Less net deferred origination fees and premiums (6,107) Loans receivable $ 2,627,256 There were $46.5 million in loans past due 90 days or more and still accruing interest as of December 31, 2023, and $26.1 million as of December 31, 2022. The increase is attributed to loans originated through CCBX lending partners which continue to accrue interest up to 180 days past due. The accrual of interest on community bank loans is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due or when they are 90 days past due as to either principal or interest, unless they are well secured and in the process of collection. Installment/closed-end, and revolving/open-end consumer loans originated through CCBX lending partners will continue to accrue interest until 120 and 180 days past due, respectively and an allowance is recorded through provision expense for these expected losses. For installment/closed-end and revolving/open-end consumer loans originated through CCBX lending partners with balances outstanding beyond 120 days and 180 days past due, respectively, principal and capitalized interest outstanding is charged off against the allowance and accrued interest outstanding is reversed against interest income. These consumer loans are reported as nonperforming/substandard, 90 days or more days past due and still accruing. When loans are placed on nonaccrual status, all accrued interest is reversed from current period earnings. Payments received on nonaccrual loans are generally applied as a reduction to the loan principal balance. If the likelihood of further loss is removed, the Company will recognize interest on a cash basis only. Loans may be returned to accruing status if the Company believes that all remaining principal and interest is fully collectible and there has been at least six months of sustained repayment performance since the loan was placed on nonaccrual. An analysis of nonaccrual loans by category consisted of the following at the periods indicated: December 31, December 31, 2023 2022 Total Nonaccrual Nonaccrual with No ACL Total Nonaccrual (dollars in thousands; unaudited) Community Bank Commercial and industrial loans $ — $ — $ 113 Real estate loans: Construction, land and land development — — 66 Residential real estate 170 170 — Commercial real estate 7,145 7,145 6,901 Consumer and other loans — — — Total nonaccrual loans $ 7,315 $ 7,315 $ 7,080 In some circumstances, the Company modifies loans in response to borrower financial difficulty, and generally provides for a temporary modification of loan repayment terms. In order for a modified loan to be considered for accrual status, the loan’s collateral coverage generally will be greater than or equal to 100% of the loan balance, the loan is current on payments, and the borrower must either prefund an interest reserve or demonstrate the ability to make payments from a verified source of cash flow for an extended period of time, usually at least six months in duration. In January 2023, the Company adopted ASU 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures” (“ASU 2022-02”), which eliminated the accounting guidance for TDRs while enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower is experiencing financial difficulty. This guidance was applied on a prospective basis. No loans were modified for community bank borrowers experiencing financial difficulty in the twelve months ended months ended December 31, 2023 . The following table presents the CCBX loans at December 31, 2023 that were both experiencing financial difficulty and were modified during the year ended December 31, 2023 by class and by type of modification. The percentage of the loans that were modified to borrowers in financial distress as compared to the total of each class of loans is also presented below.

Therefore, the loan balance is reduced by the uncollectible amount and the allowance for credit losses is adjusted by the same amount. Credit Quality and Credit Risk Federal regulations require that the Company periodically evaluate the risks inherent in its loan portfolio. In addition, the Company’s regulatory agencies have authority to identify problem loans and, if appropriate, require them to be reclassified. The Company establishes loan grades for loans at the origination of the loan. Changes to community bank loan grades are considered at the time new information about the performance of a loan becomes available, including the receipt of updated financial information from the borrower and after loan reviews. For consumer loans, the Bank follows the Federal Financial Institutions Examination Council’s Uniform Retail Credit Classification and Account Management Policy for subsequent classification in the event of payment delinquencies or default. Typically, an individual loan grade will not be changed from the prior period unless there is a specific indication of credit deterioration or improvement. Credit deterioration is evidenced by delinquency, direct communications with the borrower or other borrower information that becomes known to management. Credit improvements are evidenced by known facts regarding the borrower or the collateral property. The Company classifies some loans as Watch or Other Loans Especially Mentioned (“OLEM”). Loans classified as Watch are performing assets but have elements of risk that require more monitoring than other performing loans and are reported in the OLEM column in the following table. Loans classified as OLEM are assets that continue to perform but have shown deterioration in credit quality and require close monitoring. There are three classifications for problem loans: Substandard, Doubtful, and Loss. Substandard loans have one or more defined weaknesses and are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Revolving (open-ended loans, such as credit cards) and installment (closed end) consumer loans originated through CCBX partners continue to accrue interest until they are charged-off at 120 days past due for installment loans (primarily unsecured loans to consumers) and 180 days past due for revolving loans (primarily credit cards) and are classified as substandard. Doubtful loans have the weaknesses of loans classified as Substandard, with additional characteristics that suggest the weaknesses make collection or recovery in full after liquidation of collateral questionable on the basis of currently existing facts, conditions, and values. There is a high possibility of loss in loans classified as Doubtful. A loan classified as Loss is considered uncollectible and of such little value that continued classification of the credit as a loan is not warranted. If a loan or a portion thereof is classified as Loss, it must be charged-off, meaning the amount of the loss is charged against the allowance for credit losses, thereby reducing that reserve. Management considers the guidance in ASC 310-20 when determining whether a modification, extension, or renewal of loan constitutes a current period origination.

See Note 1, Description of Business and Summary of Significant Accounting Policies. As a result of implementing CECL, there was a one-time adjustment to the 2023 opening allowance balance of $3.9 million. CCBX loans have a higher level of expected losses than our community bank loans, which is reflected in the factors for the allowance for credit losses. Agreements with our CCBX partners provide for a credit enhancement which protects the Bank by reimbursing most losses. In accordance with accounting guidance, we estimate and record a provision for expected losses for these CCBX loans and reclassified negative deposit accounts. When the provision for CCBX credit losses and provision for unfunded commitments are recorded, a credit enhancement asset is also recorded on the balance sheet through noninterest income (BaaS credit enhancements). Expected losses are recorded in the allowance for credit losses. The credit enhancement asset is reduced when credit enhancement payments are received from the CCBX partner or taken from the partner's cash reserve account. CCBX partners provide for credit enhancements that provide protection to the Bank from credit and fraud losses by reimbursing the Bank for the losses. If the partner is unable to fulfill its contracted obligations then the Bank could be exposed to the loss of the reimbursement and credit enhancement income. In accordance with the program agreement for one CCBX partner, the Company is responsible for credit losses on approximately 10% of a $288.1 million loan portfolio that are without credit enhancement reimbursements. At December 31, 2023, 10% of this portfolio represented $29.1 million in loans. The partner is responsible for reimbursing credit losses on approximately 90% of this portfolio and for fraud losses on 100% of this portfolio. The Company earns 100% of the interest income on the aforementioned $29.1 million of loans. The following tables summarize the allocation of the ACL, as well as the activity in the ACL attributed to various segments in the loan portfolio, as of and for the year ended December 31, 2023 and the allocation and activity of the loans and allowance for loan losses ("ALLL ") attributed to the various segments in the loan portfolio for the year ended December 31, 2022: Commercial Construction, Residential Commercial Consumer Unallocated Total (dollars in thousands) Twelve Months Ended December 31, 2023 ALLL balance, December 31, 2022 $ 4,831 $ 7,425 $ 4,142 $ 5,470 $ 50,996 $ 1,165 $ 74,029 Impact of adopting CECL (ASC 326) 1,428 (1,589) 1,623 1,240 2,315 (1,165) $ 3,852 Provision for credit losses or (recapture) 9,264 550 11,921 731 161,577 — 184,043 15,523 6,386 17,686 7,441 214,888 — 261,924 Loans charged-off (6,651) — (4,641) — (140,705) — (151,997) Recoveries of loans previously charged-off 5 — 4 — 7,022 — 7,031 Net charge-offs (6,646) — (4,637) — (133,683) — (144,966) ACL balance, December 31, 2023 $ 8,877 $ 6,386 $ 13,049 $ 7,441 $ 81,205 $ — $ 116,958 Twelve Months Ended December 31, 2022 ALLL Balance, December 31, 2021 $ 3,221 $ 6,984 $ 4,598 $ 6,590 $ 7,092 $ 147 $ 28,632 Provision for credit losses or (recapture) 2,125 441 (4) (1,120) 76,604 1,018 79,064 5,346 7,425 4,594 5,470 83,696 1,165 107,696 Loans charged-off (555) — (452) — (32,742) — (33,749) Recoveries of loans previously charged-off 40 — — — 42 — 82 Net charge-offs (515) — (452) — (32,700) — (33,667) ALLL Balance, Dec

Leases [Abstract]
Leases	Leases The Company has committed to rent premises used in business operations under non-cancelable operating leases and determines if an arrangement meets the definition of a lease upon inception. Operating lease right-of-use (“ROU”) assets represent a right to use an underlying asset for the contractual lease term. Operating lease liabilities represent an obligation to make lease payments arising from the lease. Any new operating leases entered into will be recognized as an operating lease ROU asset and operating lease liability at the commencement date of the new lease. The Company’s leases do not provide an implicit interest rate, therefore the Company used its incremental collateralized borrowing rates commensurate with the underlying lease terms to determine the present value of operating lease liabilities at the inception of the lease. The weighted average discount rate of operating lease liabilities at December 31, 2023 was 4.0%. The Company’s operating lease agreements contain both lease and non-lease components, which are generally accounted for separately. The Company’s lease agreements do not contain any residual value guarantees. Operating leases with original terms of 12 months or less are not included in ROU assets and operating lease liabilities recorded in our consolidated balance sheets. Operating lease terms include options to extend when it is reasonably certain that the Company will exercise such options, determined on a lease-by-lease basis. At December 31, 2023, lease expiration dates ranged from less than two months to 21.2 years, with additional renewal options on certain leases typically ranging from 5 to 10 years. At December 31, 2023, the dollar weighted average remaining lease term for the Company’s operating leases was 9.0 years. Rental expense for operating leases is recognized on a straight-line basis over the lease term and amounted to $1.2 million and $1.4 million for the years ended December 31, 2023 and 2022, respectively. Variable lease components, such as fair market value adjustments, are expensed as incurred and not included in ROU assets and operating lease liabilities. The following sets forth, as of December 31, 2023, the minimum annual lease payments under the terms of these leases, inclusive of renewal options that the Company is reasonably certain to renew: (dollars in thousands) December 31, 2024 $ 1,016 2025 974 2026 977 2027 913 2028 692 2029 and thereafter 2,763 Total lease payments 7,335 Less: amounts representing interest 1,211 Present value of lease liabilities $ 6,124 Office space at a small number of branches is leased and sub-leased to a few tenants on month-to-month and multi-year leases. Lease and sublease income was $205,000 and $157,000 for 2023 and 2022, respectively. The following table presents the components of total lease expense and operating cash flows for the year ended December 31, 2023: For the Year Ended (dollars in thousands) December 31, December 31, December 31, Lease expense: Operating lease expense $ 1,074 $ 1,281 $ 1,283 Variable lease expense 236 193 148 Total lease expense (1) $ 1,310 $ 1,474 $ 1,431 Cash paid: Cash paid reducing operating lease liabilities $ 1,334 $ 1,473 $ 1,419 (1) Included in net occupancy expense in the Consolidated Statements of Income.

The net deferred tax asset consists of the following temporary differences and carryforward items at December 31: 2023 2022 (dollars in thousands) Deferred tax assets: Allowance for credit losses $ 27,244 $ 17,076 Lease liability 1,431 1,212 Stock based compensation 983 630 Accrued expenses 755 708 Deferred compensation 112 142 Net unrealized loss on available-for-sale securities 69 621 Other 544 522 Total deferred tax assets 31,138 20,911 Deferred tax liabilities: Credit enhancement recovery (25,030) - Right of use asset (1,386) (1,162) Depreciation and amortization (693) (977) Other (223) (314) Total deferred tax liabilities (27,332) (2,453) Net deferred tax asset $ 3,806 $ 18,458 The determination of the amount of deferred income tax assets which are more likely than not to be realized is primarily dependent on projections of future earnings, which are subject to uncertainty and estimates that may change given economic conditions and other factors. The realization of deferred income tax assets is regularly assessed and a valuation allowance is recorded if it is “more likely than not” that all or a portion of the deferred tax asset will not be realized. “More likely than not” is defined as greater than a 50% chance. All available evidence, both positive and negative is considered to determine whether, based on the weight of that evidence, a valuation allowance is needed. Based upon its analysis of available evidence, including recent profitability, management has determined that it is “more likely than not” that the Company’s deferred income tax assets as of December 31, 2023 will be fully realized and therefore no valuation allowance was recorded. CCBX partners reimburse the Bank for credit losses on loans covered by credit enhancements, therefore the credit enhancement recovery deferred tax liability partially offsets the allowance for credit losses deferred tax asset. At December 31, 2023, the Company had no federal net operating loss carryforwards or tax credit carryforwards. The Company files federal and various state income tax returns. Federal tax returns for the 2020 tax year and later are open for examination. The total amount of unrecognized tax benefits, including interest and penalties, at December 31, 2023 was not material. The amount of tax benefits that would impact the effective rate, if recognized, is not expected to be material. The Company does not anticipate any significant changes with respect to unrecognized tax benefits within the next 12 months.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions During 2023 and 2022, the Company had transactions made in the ordinary course of business with certain of its executive officers and directors. All loans included in such transactions were made on substantially the same terms, including interest rate and collateral, as those prevailing at the time for comparable transactions with other persons, and did not, in the opinion of management, involve more than normal credit risk or present other unfavorable features. A summary of loan transactions follows: 2023 2022 (dollars in thousands) Beginning Balance January 1 $ 13,427 $ 7,976 Additions — 10,296 Payments (384) (4,845) Ending Balance December 31 $ 13,043 $ 13,427 The Company held deposits of $4.0 million and $5.5 million from directors, principal shareholders and executive officers at December 31, 2023 and 2022, respectively. All deposits included in such transactions were made on substantially the same terms, including interest rate, as those prevailing at the time for comparable transactions with other persons. The Company obtains legal services from Adams and Duncan, Inc. P.S., a law firm in which one of the Company’s directors is a partner. The services provided include general legal counsel and specialized CCBX agreement counsel. The Company also uses other law firms for legal counsel and specialties such as regulatory and SEC counsel. For fiscal year ended December 31, 2023 and 2022, total payments for legal services were $1.0 million and $864,000, respectively. The Company leased one facility from a related party in 2023 and 2022. The Everett branch facility is leased from a group of investors, one of which was a director until he retired from the board in May 2023. The Everett lease originated in 1997 and has been extended multiple times. The current lease is through March 2034. Monthly rent under the Everett lease was $46,000 through March 2023 and decreased to $19,000 a month beginning in May 2023, due to a lower lease rate and a reduction in the square footage leased; rent for April of 2023 was a blended rate. Rents paid during 2023 and 2022 for the related party Everett lease totaled $316,000 and $546,000, respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the normal course of business, there are various outstanding commitments and contingent liabilities, such as commitments to extend credit and standby letters of credit, which are not reflected in the consolidated financial statements. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit and standby letters of credit is represented by the contractual or notional amount of those instruments. The Company uses the same credit policies in making such commitments as it does for instruments that are included in the consolidated balance sheets. At December 31, 2023 and 2022, the Company had a reserve for unfunded commitments of $582,000 and $974,000, respectively, included in other liabilities on the consolidated balance sheet. The following table presents commitments associated with outstanding commitments to extend credit, standby and commercial letters of credit and equity investment commitments as of the periods indicated: (dollars in thousands; unaudited) 2023 2022 Commitments to extend credit: Commercial and industrial loans $ 86,134 $ 81,568 Commercial and industrial loans - capital call lines 608,837 772,732 Construction – commercial real estate loans 92,709 109,715 Construction – residential real estate loans 20,825 32,827 Residential real estate loans 465,887 374,735 Commercial real estate loans 54,289 35,024 Consumer and other loans 1,015,738 793,563 Total commitments to extend credit $ 2,344,419 $ 2,200,164 Standby letters of credit $ 1,096 $ 3,064 Equity investment commitment $ 653 $ 988 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commercial and industrial loan commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. We evaluate each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if considered necessary by us, upon extension of credit, is based on management’s credit evaluation of the customer. The type of collateral held varies but may include accounts receivable, inventory, property and equipment, and income- producing commercial properties. As of December 31, 2023, $1.63 billion of the $2.34 billion in total commitments to extend credit were unconditionally cancelable. Standby and commercial letters of credit are conditional commitments issued by us to guarantee the performance of a customer to a third party. In the event of nonperformance by the customer, we have rights to the underlying collateral, which can include commercial real estate, physical plant and property, inventory, receivables, cash and/or marketable securities. Our credit risk associated with issuing letters of credit is essentially the same as the risk involved in extending loan facilities to our customers. No losses were incurred in 2023 or 2022 under these commitments. Commitments to extend credit on CCBX loans are included in the table above and are summarized below: (dollars in thousands; unaudited) 2023 2022 Commitments to extend credit: Commercial and industrial loans $ 9,144 $ 952 Commercial and industrial loans - capital call lines 608,837 772,732 Residential real estate loans 418,761 329,193 Consumer and other loans 1,015,156 792,447 Total commitments to extend credit $ 2,051,898 $ 1,895,324 As of December 31, 2023, $1.63 billion in CCBX commitments to extend credit are unconditionally cancelable, compared to $1.57 billion at December 31, 2022. The increase in unconditionally cancelable commitments is attributed to growth in CCBX loans. Commitments that are unconditionally cancelable allow us to better manage loan growth, credit concentrations and liquidity. We also limit CCBX partners to a maximum aggregate customer loan balance originated and held on our balance sheet, as shown in the table below. (dollars in thousands; unaudited) Type of Lending Maximum Portfolio Size Commercial and industrial loans: Capital call lines Business - Venture Capital $ 350,000 All other commercial & industrial loans Business - Small Business 305,905 Real estate loans: Home equity lines of credit Home Equity - Secured Credit Cards 375,000 Consumer and other loans: Credit cards Credit Cards - Primarily Consumer 756,614 Installment loans Consumer 933,374 Other consumer and other loans Consumer - Secured Credit Builder & Unsecured consumer 709,108 3,430,001 The Company also has agreements with certain key officers that provide for potential payments upon retirement, disability, termination, change in control and death. The Company is subject to claims and lawsuits which arise primarily in the ordinary course of business. It is the opinion of management that the disposition or ultimate resolution of such claims and lawsuits will not have a material adverse effect on the financial position of the Company.

Risks and Uncertainties [Abstract]
Concentration of Credit Risk	Concentration of Credit Risk Most of the community bank’s business activity is with customers who are concentrated in the state of Washington. Investments in municipal securities involve governmental entities within the state. Generally, amounts placed or invested in bank accounts are insured by the FDIC up to $250,000 per depositor for each account ownership category at a bank. Uninsured deposits in bank accounts held by the Company and Bank at December 31, 2023 and 2022, totaled $6.3 million and $45.4 million, respectively. Loans to the same borrower are generally limited, by state banking regulations, to 20% of the Bank’s capital and surplus. The Company manages asset quality and controls credit risk through diversification of the loan portfolio and the application of policies designed to promote sound underwriting and loan monitoring practices. The Company regularly utilizes real estate as collateral to reduce the risk of credit loss in the loan portfolio. As of December 31, 2023 and 2022, the Company has a concentration of credit in commercial real estate. Commercial real estate loans are typically secured by the Bank’s first lien position on the subject property. Standby letters of credit were granted primarily to commercial borrowers.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation Stock Options and Restricted Stock The 2018 Coastal Financial Corporation Omnibus Plan (“2018 Plan”) authorizes the Company to grant awards, including but not limited to, stock options, restricted stock units, and restricted stock awards, to eligible employees, directors or individuals that provide service to the Company, up to an aggregate of 500,000 shares of common stock. On May 24, 2021, the Company’s shareholders approved the First Amendment to the 2018 Plan, which increased the authorized plan shares by 600,000. The 2018 Plan replaces both the 2006 Plan and the Directors’ Stock Bonus Plan (“2006 Plan”). Existing awards will vest under the terms granted and no further awards will be granted under these prior plans. Shares available to be granted under the 2018 plan were 433,644 at December 31, 2023. Stock Option Awards The fair value of each option award is estimated on the date of grant using the Black-Scholes option pricing model. Expected volatilities are based on historical volatility of the Company’s stock and other factors. The Company uses the vesting term and contractual life to determine the expected life. The risk-free interest rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Compensation expense related to unvested stock option awards is reversed at date of forfeiture. There were no new options granted in the year ended December 31, 2023. A summary of stock option activity under the Company’s Plan during the year ended December 31, 2023: Options Shares Weighted- Weighted- Aggregate (dollars in thousands, except per share amounts) Outstanding at December 31, 2022 438,103 $ 8.79 4.1 $ 16,968 Granted — $ — Exercised (83,134) $ 7.43 Expired — $ — Forfeited — $ — Outstanding at December 31, 2023 354,969 $ 9.11 3.3 $ 12,531 Vested or expected to vest at December 31, 2023 354,969 $ 9.11 3.3 $ 12,531 Exercisable at December 31, 2023 181,820 $ 8.62 2.9 $ 6,508 The total intrinsic value (which is the amount by which the stock price exceeds the exercise price) of options exercised during the year ended December 31, 2023 was $2.7 million. The intrinsic value of options exercised during the year ended December 31, 2022 was $10.3 million. As of December 31, 2023, there was $804,000 of total unrecognized compensation cost related to nonvested stock options granted under the Plan. Total unrecognized compensation costs is adjusted for unvested forfeitures. The Company expects to recognize that cost over a weighted-average period of approximately 3.8 years. Compensation expense recorded related to stock options was $319,000 and $331,000 for the years ended December 31, 2023 and 2022, respectively. Restricted Stock Units In the first quarter of 2023, the Company granted 73,611 restricted stock units under the 2018 Plan to employees, which vest ratably over 4 years and 1,084 restricted stock units which vest ratably over 5 years. In the second quarter of 2023, the Company granted 9,827 restricted stock units under the 2018 Plan to employees, which vest ratably over 5 years. In the third quarter of 2023, the Company granted 4,000 restricted stock units under the 2018 Plan to employees, which vest ratably over 3 years and 2,150 restricted stock units that vest ratably over 5 years. In the fourth quarter of 2023, the Company granted no restricted stock units under the 2018 Plan. Restricted stock units provide for an interest in Company common stock to the recipient, the underlying stock is not issued until certain conditions are met. Vesting requirements include time-based, performance-based, or market-based conditions. Recipients of restricted stock units do not pay any cash consideration to the Company for the units and the holders of the restricted units do not have voting rights. The fair value of time-based and performance-based units is equal to the fair market value of the Company’s common stock on the grant date. The fair value of market-based units is estimated on the grant date using a Monte Carlo simulation model. Compensation expense is recognized over the vesting period that the awards are based. Restricted stock units are nonparticipating securities. As of December 31, 2023, there was $9.3 million of total unrecognized compensation cost related to nonvested restricted stock units. The Company expects to recognize that cost over the remaining weighted-average vesting period of approximately 3.7 years. Compensation expense recorded related to restricted stock units was $2.9 million and $1.9 million for the year ended December 31, 2023 and 2022, respectively. A summary of the Company’s nonvested restricted stock units at December 31, 2023 and changes during the year is presented below: Nonvested shares - RSUs Shares Weighted- (dollars in thousands, except per share amounts) Nonvested shares at December 31, 2022 380,151 $ 28.61 Granted 90,672 $ 42.61 Forfeited (15,032) $ 36.70 Vested (46,520) $ 30.37 Nonvested shares at December 31, 2023 409,271 $ 31.22 Restricted Stock Awards Employees There were no new restricted stock awards granted to employees in the year ended December 31, 2023.

Restricted stock awards are participating securities. As of December 31, 2023, there was $36,000 of total unrecognized compensation cost related to nonvested restricted stock awards. The Company expects to recognize that cost over the remaining weighted-average vesting period of approximately 4.1 years. Compensation expense recorded related to restricted stock awards was $9,000 for the years ended December 31, 2023 and 2022. Director’s Stock Bonus Under the 2018 Plan, eligible directors are granted stock with a total market value of approximately $45,000, and the Board Chair is granted stock with a total market value of approximately $75,000. Committee chairs receive additional stock in an amount that varies depending upon the nature and frequency of the committee meetings. The audit committee chair receives additional stock with a market value of approximately $10,000, non-financial risk and compensation committee chairs receive additional stock with a market value of approximately $7,500, and the asset liability & investment, credit and nominating & governance chairs receive additional stock with a market value of approximately $5,000. Stock is granted as of each annual meeting date and vest one day prior to the next annual meeting date. During the vesting period, the grants are considered participating securities.

Retirement Benefits [Abstract]
Employee Benefit Plans	Employee Benefit Plans 401(k) plan - The Company has a combined 401(k) and profit-sharing plan covering substantially all employees. Contributions to the 401(k) plan may consist of matching contributions for employees. Match eligibility coincides with the first of the month following hire date in accordance with the 401(k) plan. Matching contributions are usually equal to a percentage of employee compensation. The Company determines and sets 401(k) contributions each year. Company matching contributions will be approved by the board of directors annually on a discretionary basis. In 2023 and 2022, the Company provided matching contributions totaling $1.6 million and $1.3 million, respectively. Deferred compensation plan - The Company established a deferred compensation plan in 2003 for certain management personnel. Two former employees were covered by this plan and the plan is now distributing benefits to these retired individuals. The plan was designed to help supplement retirement benefits for participants. The benefits may be funded by bank-owned life insurance policies. The life insurance policies had a cash surrender value of $12.9 million and $12.7 million at December 31, 2023 and 2022, respectively. Liabilities to employees, which are being accrued over the life of the participant’s Plan, were $479,000 and $616,000 at December 31, 2023 and 2022, respectively. Compensation expense related to this Plan was $39,000 and $48,000 for the years ended December 31, 2023 and 2022, respectively. Payments of accrued benefits totaling $175,000 were made during 2023 and 2022.

Commitments and Contingencies Disclosure [Abstract]
Regulatory Matters	Regulatory Matters Banks and bank holding companies are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory (and possibly additional discretionary) actions by regulators that, if undertaken, could have a direct material effect on the financial statements of the Bank and the Company. Historically, the Company had been operating under the Small Bank Holding Company Policy Statement, which exempts bank holding companies that have total consolidated assets of less than $3.0 billion and meet other criteria from the Federal Reserve’s risk-based- and leverage capital rules. Because the Company’s consolidated assets exceeded $3.0 billion as of September 30, 2022, the Company is no longer eligible for the Federal Reserve’s Small Bank Holding Company Policy Statement and is evaluated relative to the capital adequacy standards established by the Federal Reserve. A bank holding company that crosses the $3.0 billion total consolidated assets threshold as of June 30 of a particular year is no longer permitted to file reports as a small holding company beginning the following March. The Company’s total consolidated assets were in excess of $3.0 billion as of June 30, 2023, and as a consequence, beginning in March 2024, the Company will no longer prepare and file financial reports with the Federal Reserve as a small bank holding company. Under the regulatory capital adequacy guidelines, the Company and Bank must meet specific capital adequacy guidelines that involve quantitative measures of their assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’s and Bank’s capital ratios and the Bank’s classification under the prompt corrective action guidelines are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and Bank to maintain minimum amounts and ratios of total risk-based capital, Tier 1 capital and common equity Tier 1 capital to risk- weighted assets (as defined in the regulations), and Tier 1 capital to average adjusted total consolidated assets (as defined). According to regulatory guidelines, only the amount of deferred tax assets that can be realized within the next 12 months based on projected taxable income is allowed in the computation. There were no disallowed deferred tax assets at December 31, 2023 and 2022. Under the capital adequacy guidelines on the regulatory framework for prompt corrective action (as set forth in the table on the next page), the Bank met the criteria to be considered well capitalized as of December 31, 2023 and 2022. Such determination has been made based on the Bank’s total risk-based capital ratio, Tier 1 risk-based capital ratio, common equity Tier 1 risk-based capital ratio, and leverage ratio. There have been no conditions or events since December 31, 2023, that management believes would change the Bank’s category. Under capital adequacy regulations, the Company and the Bank must maintain a capital conservation buffer of common equity Tier 1 capital of more than 2.5% above the minimum risk-based capital ratios to avoid restrictions on the payment of capital distributions and discretionary bonus payments. Management believes the Company and the Bank exceed all capital adequacy requirements to which they are subject, including the ratios described below and the capital conservation buffer, as of December 31, 2023. The Company and Bank’s actual and required capital amo unts and ratios are as follows: Actual Minimum Required for Capital Adequacy Purposes (1) Required to be Well Amount Ratio Amount Ratio Amount Ratio (dollars in thousands) December 31, 2023 Leverage Capital (to average assets) Consolidated $ 298,920 8.10 % $ 147,616 4.00 % N/A N/A Bank Only 333,848 9.06 % 147,469 4.00 % 184,336 5.00 % Common Equity Tier 1 risk-based capital ratio (to risk-weighted assets) Consolidated 295,450 9.10 % 146,137 4.50 % N/A N/A Bank Only 333,848 10.30 % 145,875 4.50 % 210,708 6.50 % Tier 1 Capital (to risk-weighted assets) Consolidated 298,920 9.20 % 194,849 6.00 % N/A N/A Bank Only 333,848 10.30 % 194,500 6.00 % 259,334 8.00 % Total Capital (to risk-weighted assets) Consolidated 385,464 11.87 % 259,799 8.00 % N/A N/A Bank Only 375,320 11.58 % 259,334 8.00 % 324,167 10.00 % December 31, 2022 Leverage Capital (to average assets) Consolidated $ 204,585 8.07 % $ 101,460 4.00 % N/A N/A Bank Only 201,783 7.96 % 101,350 4.00 % 126,687 5.00 % Common Equity Tier 1 risk-based capital ratio (to risk-weighted assets) Consolidated 201,085 11.06 % 81,834 4.50 % N/A N/A Bank Only 201,783 11.12 % 81,623 4.50 % 117,900 6.50 % Tier 1 Capital (to risk-weighted assets) Consolidated 204,585 11.25 % 109,112 6.00 % N/A N/A Bank Only 201,783 11.12 % 108,830 6.00 % 145,107 8.00 % Total Capital (to risk-weighted assets) Consolidated 252,405 13.88 % 145,483 8.00 % N/A N/A Bank Only 224,545 12.38 % 145,107 8.00 % 181,384 10.00 % (1) Presents the minimum capital adequacy requirements that apply to the Bank (excluding the capital conservation buffer) and the Company.

Prior to September 30, 2022, the Company operated under the Small Bank Holding Company Policy Statement and therefore was not subject to Basel III capital adequacy requirements.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (that is, not a forced liquidation or distressed sale). GAAP establishes a consistent framework for measuring fair value and disclosure requirements about fair value measurements. Among other things, the accounting standard requires the reporting entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s estimates for market assumptions. These two types of inputs create the following fair value hierarchy: • Level 1 – Quoted prices in active markets for identical instruments. An active market is a market in which transactions occur with sufficient frequency and volume to provide pricing information on an ongoing basis. A quoted price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available. • Level 2 – Observable inputs other than Level 1 including quoted prices in active markets for similar instruments, quoted prices in less active markets for identical or similar instruments, or other observable inputs that can be corroborated by observable market data. • Level 3 – Unobservable inputs supported by little or no market activity for financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation; also includes observable inputs from non-binding single dealer quotes not corroborated by observable market data. The estimated fair value amounts of financial instruments have been determined by the Company using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize at a future date. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. In addition, reasonable comparability between financial institutions may not be likely due to the wide range of permitted valuation techniques and numerous estimates that must be made given the absence of active secondary markets for certain financial instruments. This lack of uniform valuation methodologies also introduces a greater degree of subjectivity to these estimated fair values. Items measured at fair value on a recurring basis – The following fair value hierarchy table presents information about the Company’s assets that are measured at fair value on a recurring basis at the dates indicated: Level 1 Level 2 Level 3 Total (dollars in thousands) December 31, 2023 Available-for-sale U.S. Treasury securities $ 99,461 $ — $ — $ 99,461 U.S. Agency collateralized mortgage obligations — 43 — 43 $ 99,461 $ 43 $ — $ 99,504 December 31, 2022 Available-for-sale U.S. Treasury securities $ 97,015 $ — $ — $ 97,015 U.S. Agency collateralized mortgage obligations — 51 — 51 U.S. Agency residential mortgage-backed securities — 1 — 1 Municipals — 250 — 250 $ 97,015 $ 302 $ — $ 97,317 The following methods were used to estimate the fair value of the class of financial instruments above: Investment securities - The fair value of securities is based on quoted market prices, pricing models, quoted prices of similar securities, independent pricing sources, and discounted cash flows. Limitations: The fair value estimates presented herein are based on pertinent information available to management as of December 31, 2023 and 2022. The factors used in the fair values estimates are subject to change subsequent to the dates the fair value estimates are completed, therefore, current estimates of fair value may differ significantly from the amounts presented herein. Items measured at fair value on a nonrecurring basis – The following table presents financial assets and liabilities measured at fair value on a nonrecurring basis and the level within the fair value hierarchy of the fair value measurements for those assets at the dates indicated: Level 1 Level 2 Level 3 Total (dollars in thousands) December 31, 2023 Collateral dependent loans $ — $ — $ 7,315 $ 7,315 Equity securities 2,622 2,622 Total $ — $ — $ 9,937 $ 9,937 December 31, 2022 Impaired loans $ — $ — $ 7,080 $ 7,080 Equity securities 2,572 2,572 Total $ — $ — $ 9,652 $ 9,652 Individually evaluated loans - Fair values for individually evaluated loans are estimated using the fair value of the collateral less selling costs if the loan results in a Level 3 classification. Individually evaluated loan amounts are initially valued at the lower of cost or fair value. Individually evaluated loans carried at fair value generally receive specific allocations of the allowance for credit losses. For collateral dependent real estate loans, fair value is commonly based on recent real estate appraisals. 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 independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Individually evaluated loans are evaluated on a quarterly basis for additional credit losses and adjusted accordingly. The estimated fair values of financial instruments disclosed above follow the guidance in ASU 2016-01 which prescribes an “exit price” approach in estimating and disclosing fair value of financial instruments incorporating discounts for credit, liquidity, and marketability factors. Valuation is measured based on the fair value of the underlying collateral or the discounted cash expected future cash flows. Subsequent changes in the value of loans are included within the provision for credit losses - loans in the same manner in which it initially was recognized or as a reduction in the provision that would otherwise be reported. Loans are evaluated quarterly to determine if valuation adjustments should be recorded. The need for valuation adjustments arises when observable market prices or current appraised values of collateral indicate a shortfall in collateral value compared to current carrying values of the related loan. If the Company determines that the value of the individually evaluated loan is less than the carrying value of the loan, the Company either establishes a reserve as a specific component of the allowance for credit losses or charges off that amount. These valuation adjustments are considered nonrecurring fair value adjustments. Equity securities – The Company measures equity securities without readily determinable fair values at cost less impairment (if any), plus or minus observable price changes from an identical or similar investment of the same issuer, with price changes recognized in earnings . Assets measured at fair value using significant unobservable inputs (Level 3) The following table presents the carrying value of equity securities without readily determinable fair values, as of December 31, 2023, 2022 and 2021, with adjustments recorded during the periods presented for those securities with observable price changes, if applicable. These equity securities are included in other investments on the balance sheet.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting As defined in ASC 280, Segment Reporting , an operating segment is a component of an enterprise that engages in business activities from which it may earn revenues and incur expenses, whose operating results are regularly reviewed by the enterprise’s chief operating decision makers to make decisions about resources to be allocated to the segment and assess its performance, and for which discrete financial information is available. We evaluate performance based on an internal performance measurement accounting system, which provides line of business results. This system uses various techniques to assign balance sheet and income statement amounts to the business segments, including allocations of income and expense. A primary objective of this measurement system and related internal financial reporting practices are to produce consistent results that reflect the underlying financial impact of the segments on the Company and to provide a basis of support for strategic decision making. The accounting policies applicable to our segments are those that apply to our preparation of the accompanying Consolidated Financial Statements. Based on these criteria, we have identified three segments: The community bank, CCBX and treasury & administration. Financial information concerning the Company's reportable segments and the reconciliation to the consolidated financial results is shown in the following tables for the periods indicated. The segment structure changed after 2021, therefore some items are reported as “N/A” for the year ended December 31, 2021.

Estimates	Estimates
Subsequent Events	Subsequent Events - The Company has evaluated events and transactions subsequent to December 31, 2023 for potential recognition or disclosure
Cash Equivalents and Cash Flows	Cash equivalents and cash flows - For purposes of reporting cash flows, cash and cash equivalents include cash on hand and in banks and interest-bearing deposits. All have original maturities of three months or less. CDs with other financial institutions, federal funds sold and cash flows from loans and deposits are reported as net increases or decreases under cash flows from investing activities or from financing activities. The Company maintains its cash in depository institution accounts, which, at times, may exceed federally insured limits. The Company monitors these institutions and has not experienced any losses in such accounts.
Investment Securities	Investment securities - Debt securities that management has the ability and intent to hold to maturity are classified as held-to-maturity and carried at amortized cost. The amortization of premiums and accretion of discounts are recognized in interest income using the interest method or methods approximating the interest method over the period to maturity. Debt securities not classified as held-to-maturity are classified as available-for-sale. Such securities may be sold to facilitate the Company’s asset/liability management strategies and in response to changes in interest rates and similar forces. Securities available-for-sale are carried at fair value with unrealized gains and losses reported in other comprehensive income. Realized gains (losses) on securities available-for-sale are included in noninterest income and, when applicable, are reported as a reclassification adjustment in other comprehensive income. Gains and losses on sales of securities are recorded on the trade date and are determined on the specific-identification method. For available-for-sale debt securities, if fair value is below amortized cost, the security is considered impaired. When the Company does not intend to sell the debt security, and it is more likely than not the Company will not have to sell the security before recovery of its cost basis, then the Company assesses the security for potential expected credit losses. Impairment related to a credit loss is measured using the discounted cash flow method. Credit loss recognition is limited to the fair value of the security. The impairment is recognized by establishing an ACL through provision for credit losses. Impairment related to noncredit factors is recognized in accumulated other comprehensive income, net of applicable taxes. The Company evaluates AFS security impairment on a quarterly basis. For held-to-maturity debt securities, expected losses are evaluated and calculated on a collective basis for those securities which share risk characteristics. The Company aggregates similar securities and reports the security portfolio segments based on shared risk characteristics. The only segment included in the held-to-maturity portfolio are U.S. Agency Residential Mortgage Backed Securities which have an expected zero credit loss and were purchased for CRA purposes.
Other Investments	Other investments - Other investments on the balance sheet consists of direct equity investments in stock of the Federal Home Loan Bank of Des Moines (“FHLB”), the Federal Reserve Bank of San Francisco (“FRB”), Pacific Coast Banker’s Bancshares, as well as investments in bank technology funds. As a Federal Reserve member bank, the Bank is required to own stock in the FRB in an amount based on the Bank’s capital. The recorded amount of the FRB stock equals its fair value because the shares can only be redeemed by the FRB at their par value. The Bank’s investment in FRB stock was $4.8 million and $4.3 million at December 31, 2023 and 2022, respectively. The Bank, as a member of the FHLB, is required to maintain an investment in capital stock of FHLB in an amount equal to 4.5% of advances outstanding, plus 0.06% of total assets from the prior fiscal year end. The recorded amount of FHLB stock equals its fair value because the shares can only be redeemed by FHLB at the $1 per share par value. The investment in FHLB stock was $1.9 million and $3.2 million at December 31, 2023 and 2022, respectively. The investment in Pacific Coast Banker’s Bancshares (“PCBB”) stock consists of an equity security. This investment is carried at its cost of $100,000 at December 31, 2023 and 2022, which approximates its fair value. The Company has the following equity investments which do not have a readily determinable fair value and are held at cost minus impairment if any, plus or minus observable price changes in orderly transactions for an identical or similar investment of the same issuer. This method will be applied until the investments do not qualify for the measurement election (e.g., if the investment has a readily determinable fair value). The Company will reassess at each reporting period whether the equity investments without a readily determinable fair value qualifies to be measured at cost minus impairment. These equity investments without a readily determined fair value include: • The Company has a $2.2 million equity interest in a specialized bank technology company as of December 31, 2023 and December 31, 2022 . • The Company has a $350,000 equity interest in a technology company as of the years ended December 31, 2023 and December 31, 2022. • The Company contributed $50,000 to a technology company during the year ended December 31, 2023, there was no equity ownership as of December 31, 2022.
Loans and Allowance for Loan Losses	Loans and allowance for credit losses – Loans are stated at the principal amount outstanding less the allowance for credit losses and net of any deferred fees or costs on originated loans, and unamortized premiums or discounts on purchased loans. Loan fees and certain direct loan origination costs are deferred, and the net fee or cost is recognized as an adjustment to interest income using the level yield methodology and a method that approximates the level yield methodology. Interest income on loans is recognized based upon the principal amounts outstanding. The accrual of interest on community bank loans is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due or when they are 90 days past due as to either principal or interest, unless they are well secured and in the process of collection. When interest accrual is discontinued, all unpaid accrued interest is reversed against current income. If management determines that the ultimate collectability of principal or interest is in doubt, cash receipts on nonaccrual loans are applied to reduce the principal balance on a cash-basis method, until the loans qualify for return to accrual status or principal is paid in full. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current, borrower has demonstrated ability to make regular payments, generally a period of at least six months, and future payments are reasonably assured. For installment/closed-end, and revolving/open-end consumer loans originated through CCBX lending partners loans will accrue interest until 120 and 180 days past due, respectively, which is consistent with regulatory guidelines for consumer loans of this nature, and an allowance is recorded through provision expense for these expected losses. For installment/closed-end and revolving/open-end consumer loans originated through CCBX lending partners with balances outstanding beyond 120 days and 180 days, respectively, principal and capitalized interest outstanding is charged off against the allowance and accrued interest outstanding is reversed against interest income. The allowance for credit losses is comprised of amounts charged against income in the form of the provision for credit losses, less charged-off loans, net of recoveries. When available information confirms that specific loans or portions thereof are uncollectible, identified amounts are charged against the allowance for credit losses. The existence of some or all of the following criteria will generally confirm that a loss has been incurred: (1) the loan is significantly delinquent and the borrower has not demonstrated the ability or intent to bring the loan current; (2) the Company has no recourse to the borrower or if it does, the borrower has insufficient assets to pay the debt; (3) the estimated fair value of the loan collateral is significantly below the current loan balance; and (4) there is little or no near-term prospect for improvement. Subsequent recoveries, if any, are credited to the allowance for credit losses. The allowance for credit losses ("ACL") is an estimate of the expected credit losses on financial assets measured at amortized cost. The ACL is evaluated and calculated on a collective basis for those loans which share similar risk characteristics. At each reporting period, the Company evaluates whether the loans in a pool continue to exhibit similar risk characteristics as the other loans in the pool and whether it needs to evaluate the allowance on an individual basis. The Company must estimate expected credit losses over the loans’ contractual terms, adjusted for expected prepayments. In estimating the life of the loan, the Company cannot extend the contractual term of the loan for expected extensions, renewals, and modifications, unless the extension or renewal options are included in the contract at the reporting date and are not unconditionally cancellable by the Company. Because expected credit losses are estimated over the contractual life adjusted for estimated prepayments, determination of the life of the loan may significantly affect the ACL. The Company has chosen to segment its portfolio consistent with the manner in which it manages the risk of the type of credit. • Community Bank Portfolio: The ACL calculation is derived from loan segments utilizing loan level information and relevant available information from internal and external sources related to past events and current conditions. In addition, the Company incorporates a reasonable and supportable forecast. • CCBX Portfolio: The Bank calculates the ACL on loans on an aggregate basis based on each partner and product level, segmenting the risk inherent in the CCBX portfolio based on qualitative and quantitative trends in the portfolio. Also included in the ACL are qualitative reserves to cover losses that are expected, but in the Company’s assessment may not be adequately represented in the quantitative method. For example, factors that the Company considers include environmental business conditions, borrower’s financial condition, credit rating and the volume and severity of past due loans and non-accrual loans. Based on this analysis, the Company records a provision for credit losses to maintain the allowance at appropriate levels. Determining the amount of the allowance is considered a critical accounting estimate, as it requires significant judgment and the use of subjective measurements, including management’s assessment of overall portfolio quality. The Company maintains the allowance at an amount the Company believes is sufficient to provide for estimated losses expected to occur in the Company’s loan portfolio at each balance sheet date, and fluctuations in the provision for credit losses may result from management’s assessment of the adequacy of the allowance. Changes in these estimates and assumptions are possible and may have a material impact on the Company’s allowance, and therefore the Company’s financial position, liquidity or results of operations. The Company has elected to exclude accrued interest receivable from the amortized cost basis in its ACL calculation as accrued interest is written off in a timely manner when deemed uncollectible. For more information and discussion related to the allowance for credit losses on loans, see “Note 4 - Loans and Allowance for Credit Losses” in the Consolidated Financial Statements. In addition to the ACL on loans held for investment, CECL requires a balance sheet liability for expected losses on unfunded commitments, which is recognized if both the following conditions are met: (1) the Company has a present contractual obligation to extend credit; and (2) the obligation is not unconditionally cancellable by the Company. Loan commitments may have a funded and unfunded portion, of which the liability for unfunded commitments is derived based upon the commitments to extend credit to a borrower. The expected credit losses for funded portions are reported in the previously discussed ACL.
Loans Held-for-Sale	Loans held-for-sale - During the year ended December 31, 2023, the Company transferred $599.9 million in CCBX loans receivable to loans held for sale. The loans sold to the originating partners are in accordance with partner agreements and are primarily sold for credit and concentration management. As of December 31, 2023 and 2022 there were no loans held for sale. Community bank loans held-for-sale consist of the guaranteed portion of SBA loans and USDA loans the Company intends to sell after origination and are reflected at the lower of aggregate cost or fair value. Loans are generally sold with servicing of the sold portion retained by the Company when the sale of the loan occurs, the premium received is combined with the estimated present value of future cash flows on the related servicing asset and recorded as a gain on sale of loans in noninterest income. There were no loans held for sale at December 31, 2023 and 2022.
Loan Sales Recognition	Loan sales recognition - The Company recognizes a sale on loans if the transferred portion (or portions) and any portion that continues to be held by the transferor are participating interests. Participating interest is defined as a portion of a financial asset that (a) conveys proportionate ownership rights with equal priority to each participating interest holder, (b) involves no recourse (other than standard representations and warranties), and (c) does not entitle any participating interest holder to receive cash before any other participating interest holder. The transfer of the participating interest (or participating interests) must also meet the conditions for surrender of control. To determine the gain or loss on sale of loans, the Company’s investment in the loan is allocated among the retained portion of the loan, the servicing retained, and the sold portion of the loan, based on the relative fair market value of each portion. The gain or loss on the sold portion of the loan is based on the difference between the sale proceeds and the allocated investment in the sold portion of the loan. A discount is recorded against the carrying value of the retained portion of the loan to offset the decrease in the fair value allocation of said retained portion. The Company retains the servicing on the sold guaranteed portion of SBA and USDA loans. The Company receives a fee for servicing the loan. The Company also retains the servicing on the sold guaranteed portion of Main Street Lending Program (“MSLP”) loans. The net deferred fee on the sold portion of the loan is recognized when sold. The Company does not retain the servicing on sold CCBX loans.
Reserve for Unfunded Commitments	Reserve for unfunded commitments
Premises and Equipment	Premises and equipment - Premises and equipment are stated at cost less accumulated depreciation. Depreciation expense is computed using the straight-line method based upon the estimated useful lives of the assets. Asset lives range from three . Leasehold improvements are amortized over the expected term of the lease including options to extend which are reasonably certain to be exercised or the estimated useful life of the improvement, whichever is less. The Company capitalizes internal and external costs related to internal-use software during the application development stage, including consulting costs and compensation expenses related to employees who devote time to the development of the projects. The Company records capitalized software development costs in premises and equipment in the Consolidated Balance Sheets. Costs incurred in preliminary stages of development activities and post implementation activities are expensed in the period incurred. The Company may also capitalize costs related to specific upgrades and enhancements when it is probable the expenditures will result in additional functionality. Once the software is substantially complete and ready for its intended use, capitalization ceases and the asset is amortized straight line over its estimated useful life, which is typically three years. Maintenance and repairs are charged to operating expenses. Renewals and betterments are added to the asset accounts and depreciated over the periods benefited. Depreciable assets sold or retired are removed from the asset and related accumulated depreciation accounts and any gain or loss is reflected in the income statement. These assets are reviewed for impairment when events indicate their carrying value may not be recoverable. If management determines impairment exists, the asset is reduced with an offsetting charge to the income statement.
Transfers of Financial Assets	Transfers of financial assets - Transfers of an entire financial asset are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when: (1) a group of financial assets or a participating interest in an entire financial asset has been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Other Real Estate Owned and Repossessed Assets	Other real estate owned and repossessed assets - Other real estate owned and repossessed assets are foreclosed property held pending disposition and are initially recorded at fair value less estimated selling costs when acquired, establishing a new cost basis. At foreclosure, if the fair value of the asset acquired less estimated selling costs is less than the Company’s recorded investment in the related loan, a write-down is recognized through a charge to the allowance for credit losses. Costs of significant property improvements that increase the value of the property are capitalized, whereas costs relating to holding the property are expensed. Valuations are periodically performed by management, and a valuation allowance is established for subsequent declines, which are recorded as a charge to income, if necessary, to reduce the carrying value of the property to its fair value less estimated selling costs.
Leases	Leases - The Company accounts for its leases in accordance with ASC 842 - Leases . Most leases are recognized on the balance sheet by recording a right-of-use asset and lease liability for each lease. The right-of-use asset represents the right to use the asset under lease for the lease term, and the lease liability represents the contractual obligation to make lease payments. The right-of-use asset is tested for impairment whenever events or changes in circumstances indicate the carrying amount may not be recoverable. As a lessee, the Company enters into operating leases for certain Bank branches. The right-of-use assets and lease liabilities are initially recognized based on the net present value of the remaining lease payments which include renewal options where the Company is reasonably certain they will be exercised. The net present value is determined using the incremental collateralized borrowing rate at commencement date. The right-of-use asset is measured at the amount of the lease liability adjusted for any prepaid rent, lease incentives and initial direct costs incurred. The right-of-use asset and lease liability is amortized over the individual lease terms. Lease expense for lease payments is recognized on a straight-line basis over the lease term. For additional information regarding leases, see Note 6.
Income taxes	Income taxes
Stock-Based Compensation	Stock-based compensation - Compensation expense is recognized for stock options and restricted stock, based on the fair value of these awards at the grant date. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the grant date is used for restricted stock awards and restricted stock units and is determined on the basis of objective criteria including trade data. Compensation cost is recognized over the requisite service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.
Earnings Per Common Share	Earnings per common share - Earnings per common share (“EPS”) is computed under the two-class method. Pursuant to the two-class method, nonvested stock based payment awards that contain non-forfeitable rights to dividends or dividend equivalents are participating securities and are included in the computation of EPS. The two-class method is an earnings allocation formula that determines earnings per share for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. Application of the two-class method resulted in the equivalent earnings per share to the treasury method. Basic earnings per common share is computed by dividing net earnings allocated to common shareholders by the weighted-average number of common shares outstanding during the applicable period, excluding outstanding participating securities. Diluted earnings per common share is computed using the weighted-average number of shares determined for the basic earnings per common share computation plus the dilutive effect of stock using the treasury stock method. Stock options that are anti-dilutive are not included in the calculation of diluted EPS.
Comprehensive Income	Comprehensive income - Accounting principles generally require that recognized revenue, expenses, gains, and losses be included in net income. Certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale investments, are reported as a separate component of the shareholders’ equity section of the balance sheets. Accumulated other comprehensive income consists of only one component: unrealized gains or losses on investment securities available-for-sale.
Business Segments	Business Segments – For financial reporting purposes, the Company has three segments: The community bank, CCBX and treasury & administration. The community bank business is that of a traditional banking institution, gathering deposits and originating loans for portfolio in its market areas. The community bank offers a wide variety of deposit products to their customers. Lending activities include the origination of real estate, commercial and industrial, and consumer loans. Interest income on loans is the Company’s primary source of revenue, and is supplemented by interest income from investment securities, deposit service charges, and other service provided activities. The CCBX segment provides banking as a service (“BaaS”) that allows our broker-dealer and digital financial service partners to offer their customers banking services. The CCBX segment has 21 partners as of December 31, 2023. The treasury & administration segment includes treasury management, overall administration and all other aspects of the Company. The performance of the Company is reviewed and monitored by the Company’s executive management on a daily basis and the Board of Directors reviews and monitors the performance of the Company at minimum, on a monthly basis. For additional information regarding the business segments, see Note 21.
