Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Nature of Operations and Principles of Consolidation Five Star Bank (the “Bank”) was chartered on October 26, 1999 and began operations on December 20, 1999. Five Star Bancorp (“Bancorp” or the “Company”) was incorporated on September 16, 2002 and subsequently obtained approval from the Federal Reserve to be a bank holding company in connection with its acquisition of the Bank. The Company became the sole shareholder of the Bank on June 2, 2003 in a statutory merger, pursuant to which each outstanding share of the Bank’s common stock was exchanged for one share of common stock of the Company. The Company, through the Bank, provides a broad range of banking products and services to customers who are predominately small and medium-sized businesses, professionals, and individuals primarily in the Northern California region. The Company’s primary loan products are commercial real estate loans, land development loans, construction loans, and operating lines of credit, and its primary deposit products are checking accounts, savings accounts, money market accounts, and term certificate accounts. The Bank currently has seven branch offices in Roseville, Natomas, Rancho Cordova, Redding, Elk Grove, Chico, and Yuba City. The Company terminated its status as a Subchapter S corporation as of May 5, 2021, in connection with the Company’s IPO and became a taxable C Corporation. Prior to that date, as an S Corporation, the Company had no U.S. federal income tax expense. The Company publicly filed a Registration Statement on Form S-1 with the SEC in connection with its IPO, which was declared effective by the SEC on May 4, 2021. In connection with the IPO, the Company issued 6,054,750 shares of common stock, no par value, which included 789,750 shares sold pursuant to the underwriters’ exercise of their option to purchase additional shares. The securities were sold to the public at a price of $20.00 per share and began trading on the Nasdaq Global Select Market on May 5, 2021. On May 7, 2021, the closing date of the IPO, the Company received total net proceeds of $111,243,000. The net proceeds less other related expenses, including audit fees, legal fees, listing fees, and other expenses, totaled $109,082,000. Basis of Financial Statement Presentation and Consolidation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) as contained within the FASB’s ASC, including ASU, and the rules and regulations of the SEC, including the instructions to Regulation S-X. The consolidated financial statements include Bancorp and its wholly owned subsidiary, the Bank. All significant intercompany transactions and balances are eliminated in consolidation. While the Company’s chief decision-makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Discrete financial information is not available other than on a Company-wide basis. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment. The Company’s accounting and reporting policies conform to GAAP and to general practices within the banking industry. The Company qualifies as an emerging growth company as defined in the Jumpstart Our Business Startups Act of 2012, and a smaller reporting company, and, as such, may take advantage of specified reduced reporting requirements and is relieved of other significant requirements that are otherwise generally applicable to other public companies. Use of Estimates Management is required 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions affect the amounts reported in the consolidated financial statements and the disclosures provided, and actual results could differ. The allowance for credit losses is the most significant accounting estimate reflected in the Company’s consolidated financial statements. Other estimates include fair value measurements, valuation of servicing assets, and deferred tax asset valuation. Cash and Cash Equivalents The Company defines cash and cash equivalents as cash, due from financial institutions, interest-bearing deposits in banks with short-term original maturities, and federal funds sold. Generally, federal funds are sold for one-day periods, if at all. At times throughout the year, balances can exceed FDIC insurance limits. The Company has not experienced any historical losses associated with balances maintained with financial institutions in excess of FDIC insurance limits, and management continues to monitor the financial condition of the major financial institutions where these funds are held. Securities Available-for-Sale Available-for-sale securities consist of bonds, notes, and debentures not classified as trading securities or held-to-maturity securities. Securities are classified as available-for-sale if the Company intends and has the ability to hold those securities for a period of time, but not necessarily to maturity. Any decision to sell a security classified as available-for-sale would be based on various factors, including significant movements in interest rates, changes in the maturity mix of assets and liabilities, liquidity needs, regulatory capital considerations, and other similar factors. Securities available-for-sale are carried at fair value. Unrealized holding gains or losses are included in other comprehensive income as a separate component of shareholders’ equity, net of tax. Realized gains or losses, determined based on the cost of specific securities sold, are included in earnings. Premiums are amortized over the life of the security or, if a callable bond, over the earliest call date, and discounts are accreted over the life of the related investment security as an adjustment to interest income using the effective interest method. Interest income is recognized when earned. Unrealized credit losses are recognized through an allowance for credit losses instead of an adjustment to amortized cost basis, eliminating the other-than-temporary impairment concept. For available-for-sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more likely than not that it will be required to sell, the security before recovery of amortized cost basis. If either criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through earnings. For available-for-sale debt securities that do not meet the above conditions, the Company evaluates at the individual security level whether the decrease in fair value has resulted from credit factors or non-credit factors. If assessment determines that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis of the security, then a credit loss would be recognized, limited to the amount by which the fair value is less than the amortized cost basis. All other changes in fair value of an available-for-sale debt security are recognized in other comprehensive income, net of applicable taxes. Changes in the allowance for credit losses, if any, are recognized as a provision for (or reversal of) credit losses. Accrued interest receivable is not subject to an estimate for credit loss, as the Company has a policy to charge off accrued interest deemed uncollectible in a timely manner. Securities Held-to-Maturity Securities are classified as held-to-maturity if the Company has both the intent and ability to hold those securities to maturity regardless of changes in market conditions, liquidity needs, or changes in general economic conditions. These securities are carried at cost adjusted for amortization of premium to the earliest callable call date and accretion of discount, computed by the effective interest method over the life of the related investment. Estimated credit losses are recorded under ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and all subsequent amendments that modified ASU 2016-13 (collectively, “ASC 326”) through a credit loss expense and an allowance. Accrued interest receivable is not subject to an estimate for credit loss, as the Company has a policy to charge off accrued interest deemed uncollectible in a timely manner. Loans Loans are reported at the principal amount outstanding, net of deferred loan fees and costs and the allowance for credit losses - loans. Interest on loans is accrued daily based on the principal outstanding. Loan fees, net of certain direct costs of origination, are deferred and recognized in interest income using the level-yield method without anticipating prepayments. During the years ended December 31, 2023 and 2022, salaries and employee benefits totaling $3,461,000 and $6,155,000, respectively, were deferred as loan origination costs. Loans on which the accrual of interest has been discontinued are designated as non-accrual loans. Accrual of interest on loans is discontinued either when reasonable doubt exists as to the full and timely collection of interest or principal or when a loan becomes contractually past due by 90 days or more with respect to interest or principal. When a loan is placed on non-accrual status, all interest previously accrued, but not collected, is reversed against current period interest income. Income on such loans is then recognized only to the extent that cash is received and where the future collection of principal is probable. Interest accruals are resumed on such loans only when they are brought fully current with respect to interest and principal and when, in the judgment of management, the loans are estimated to be fully collectible as to both principal and interest. ACL The ACL is a valuation account that offsets the amortized cost basis of loans receivable and certain other financial assets, including unfunded loan commitments and held-to-maturity debt securities. Under ASC 326, amortized cost basis is the basis on which the ACL is determined. Amortized cost basis on loans receivable is principal outstanding, net of any purchase premiums and discounts, and net of any deferred loan fees and costs. Credit losses are charged off when management believes that the collectability of at least some portion of outstanding principal is unlikely. These charge-offs are recorded as a reversal to, thereby reducing, the allowance for credit losses. Subsequent recoveries of previously charged-off amounts, if any, are recorded as a provision to, thereby increasing, the allowance for credit losses. The allowance for credit losses is maintained at a level to absorb expected credit losses over the contractual life, including consideration of prepayments. Determining the adequacy of the allowance is complex and requires judgments that are inherently subjective, as it requires estimates that are susceptible to revision as additional information becomes available. While the Company has determined an allowance for credit losses it considers appropriate, there can be no assurance that the allowance will be sufficient to absorb future losses. The Company’s process for determining expected lifetime credit losses entails a loan-level, model-based approach and considers a broad range of information, including historical loss experience, current conditions, and reasonable and supportable forecasts. Credit loss is estimated for all loans. Accordingly, the Company has stratified the full loan population into segments sharing similar characteristics to perform the evaluation of the credit loss collectively. The Company can also further stratify loans of similar types, risk attributes, and methods for credit risk monitoring. The Company has determined pools based primarily on regulatory reporting codes as the loans within each pool share similar risk characteristics and there is sufficient historical peer loss data from the FFIEC to provide statistically meaningful support in the models developed. The Company further stratified the C&I portfolio into traditional C&I loans and SBA loans, as the loans in these pools have different repayment structures and credit risk characteristics. The Company also stratified C&I loans and consumer loans that do not require reserves, as the Company has third party agreements in place to cover credit losses. The Company has identified the following pools subject to an estimate of credit loss: (1) 1-4 Family Construction; (2) Other Construction; (3) Farmland; (4) Revolving Secured by 1-4 Family; (5) Residential Secured by First Liens; (6) Residential Secured by Junior Liens; (7) Multifamily; (8) CRE Owner Occupied; (9) CRE Non-Owner Occupied; (10) Agriculture; (11) C&I; (12) C&I SBA; (13) Consumer; and (14) Municipal. The Company has determined, given its limited loss experience, that peer data and other external data to support loss history provides the best basis for its assessment of expected credit losses. The Company believes that the use of peer loss data from 2008 to 2019 presents loss histories that appropriately reflect a full economic cycle, reflects asset-specific risk characteristics at each pool level identified, and includes a historical look-back period that is objective and reflective of future expected credit losses. Loss data from 2020 and beyond was excluded from the data set to exclude pandemic-related data in the models. The method for determining the estimate of lifetime credit losses includes, among other things, the following main components: (i) the use of Probability of Default and Loss Given Default assumptions under a Discounted Cash Flow model; (ii) a multi-scenario macroeconomic forecast; (iii) an initial and reasonable and supportable forecast period of one year for all loan segments; and (iv) a reversion period of one year using a linear transition method to historical loss rates. Given the inherent limitations of a quantitative-only model, qualitative adjustments are included to factor in data points not captured from a quantitative analysis alone. Qualitative criteria that can be considered includes, among other things, the following: • Concentrations – the existence and effect of any concentrations of credit, and changes in the level of such concentrations; • Volume – changes in the nature and volume of the portfolio and in the terms of the loans; • Economic – changes in international, national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments; • Policy – changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses; • Quality – changes in the volume and severity of past due loans, the volume of non-accrual loans, and the volume and severity of adversely classified or graded loans; and • External – the effect of other external factors, such as competition and legal and regulatory requirements on the level of estimated credit losses in the Company’s loan portfolio. Management reviews current information on a quarterly basis to assess the forecasted future economic impact for purposes of evaluating the adequacy of the ACL. The forecasted direction and magnitude of change with respect to future economic conditions is then assessed against the estimate in the model. Any changes resulting from the quarterly assessment are recorded in “Provision for credit losses” in the unaudited consolidated statements of income. The Audit Committee of the board of directors reviews the adequacy of the allowance at least quarterly. Accrued interest receivable is excluded from amortized cost of all financial instrument types and included in “Interest receivable and other assets” in the consolidated balance sheets. Accrued interest receivable is not subject to an estimate for credit loss, as the Company has a policy to charge off accrued interest deemed uncollectible in a timely manner. When a loan is placed on non-accrual status, which occurs within 90 days of a borrower becoming delinquent, interest previously accrued but not collected is reversed against current period income. If an individual loan’s characteristics have deteriorated to below a range of the overall pool, the loan would be individually assessed. Individually assessed loans are measured for credit loss based on one of the following methods: (i) present value of future expected cash flows, discounted at the loan’s effective interest rate; (ii) amount by which carrying value of the loan exceeds the loan’s observable market price; or (iii) the fair value of the collateral, less estimated selling costs, if the loan is collateral dependent. The Company applies the practical expedient and defines collateral dependent loans as those where the borrower is experiencing financial difficulty and on which payment is expected to be provided substantially through the operation or sale of the collateral. Troubled Debt Restructurings (“TDRs”) and Other Loan Modifications In accordance with the adoption of ASC 326, which includes ASU No. 2022-02, Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures , accounting guidance for TDRs for creditors has been eliminated. New guidance with respect to recognition, measurement, and disclosures of loans for borrowers experiencing financial difficulties supersedes guidance on TDRs. Under ASU No. 2022-02, the Company is required to evaluate whether a loan modification represents a new loan or a continuation of an existing loan. The amendment enhanced existing disclosure requirements and introduced new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty under criteria of principal forgiveness, interest rate reduction, other-than-insignificant payment delay, or term extension. Federal Home Loan Bank Stock Federal Home Loan Bank stock represents the Company’s investment in the stock of the FHLB and is carried at par value. While technically these are considered equity securities, there is no market for FHLB stock. Therefore, the shares are considered as other investment securities. Management periodically evaluates FHLB stock for impairment. Management’s determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as: (i) the significance of any decline in net assets of the FHLB, as compared to the capital stock amount for the FHLB and the length of time this situation has persisted; (ii) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB; (iii) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB; and (iv) the liquidity position of the FHLB. Both cash and stock dividends are reported as non-interest income. Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are provided for in amounts sufficient to relate the cost of depreciable assets to operations over their estimated service lives using a straight-line basis. The normal estimated lives used in determining depreciation are as follows: Equipment 3 - 12 years Furniture and fixtures 5 - 10 years Leasehold improvements 5 - 15 years Automobiles 3 - 5 years Leasehold improvements are amortized over the lesser of the useful life of the asset or the remaining term of the lease. The straight-line method of depreciation is followed for all assets for financial reporting purposes, but accelerated methods are used for tax purposes. When assets are sold or otherwise disposed of, the cost and related accumulated depreciation or amortization are removed from the accounts, and any resulting gain or loss is recognized in income for the period. The cost of maintenance and repairs is charged to expense as incurred. Other Real Estate Real estate properties acquired through, or in lieu of, loan foreclosure, are classified as OREO, are to be sold, and are initially recorded at fair value of the property at the date of foreclosure less estimated selling costs. Any write-downs in value are recorded against the allowance for credit losses. Subsequent to foreclosure, valuations are periodically performed, and any revisions in the estimate of fair value are reported as adjustments to the carrying value of the real estate, provided the adjusted carrying amount does not exceed the original amount at foreclosure. Subsequent valuation adjustments are recognized as OREO write-downs. Revenues and expenses incurred from OREO property management are recorded in non-interest income and non-interest expense, respectively. During 2023 and 2022, the Bank did not foreclose on any loans. BOLI BOLI is recorded at the amount that can be realized under the insurance contract at the consolidated balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Increases in contract value are recorded as non-interest income, and insurance proceeds received are recorded as a reduction of the contract value. Long-Term Assets Premises, equipment, and other long-term assets are reviewed for impairment when events indicate that their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are adjusted to reflect their fair value. Leases The Company records a ROUA in the consolidated balance sheets for those leases that convey rights to control use of identified assets for a period of time in exchange for consideration. The Company records a lease liability in the consolidated balance sheets for the present value of future payment commitments. All of the Company’s leases are comprised of operating leases in which the Company is the lessee of real estate property for branches and operations. The Company elected not to include short-term leases (i.e., leases with initial terms of 12 months or less) within the ROUA and lease liability. Equity Investments Equity investments with readily determinable fair values are carried at fair value, with changes in fair value reported in net income. Equity investments without readily determinable fair values are carried at cost, less impairment, if any, and adjusted for changes resulting from observable price changes in orderly transactions for the identical or similar investment. Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Transfers of Financial Assets Transfers of an entire financial asset, a group of financial assets, or a participating interest in an entire financial asset are accounted for as sales when control has been relinquished. Control is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of more than trivial conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Included in the loan portfolio are loans guaranteed by the SBA, the Farm Service Agency, the Federal Agriculture Mortgage Corporation, and the United States Department of Agriculture, of which the guaranteed portion is expected to be sold in the secondary market in exchange for a one-time premium. At the time the guaranteed portion of the loan is sold, the unguaranteed portion and related right to service the entire loan is retained with the Company, to earn future servicing income. The loans held for sale are accounted for at the lower of cost or fair value, using the aggregate method. Government-guaranteed loans Servicing rights acquired through the origination of loans, which are subsequently sold with servicing rights retained, are recognized as separate assets or liabilities. Servicing assets and liabilities are initially recorded at fair value and are subsequently amortized in proportion to, and over the period of, the related net servicing income or expense. The amortized assets are assessed for impairment or increased obligations at the loan level, based on the fair value on a periodic basis. Loan Commitments and Related Financial Instruments Financial instruments include off-balance sheet credit instruments, such as commitments to make loans, and financial standby letters of credit issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded. Loan commitments not unconditionally cancellable are subject to an estimate of credit loss under the CECL model. The Company’s process for determining the estimate of credit loss on loan commitments is the same as it is on loans. Reserves for unfunded commitments are included as a component of “Interest payable and other liabilities” in the consolidated balance sheets. Stock-Based Compensation Compensation cost is recognized for stock options and restricted stock awards (“RSAs”) issued to executives, directors, and employees, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the grant date fair value of stock options, while the fair value of the Company’s common stock at the date of grant is used for RSAs. Compensation cost is recognized over the required 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. Supplemental Executive Retirement Plan The Bank has entered into a non-qualified retirement plan for the Chief Executive Officer based on a continuation of employment. The present value of annual post-retirement payments is allocated to expense over the years of required service. Income Taxes The Company files its income taxes on a consolidated basis with its subsidiary. The allocation of income tax expense represents each entity’s proportionate share of the consolidated provision for income taxes. Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. The Company accounts for uncertain tax positions in accordance with FASB ASC Topic No. 740, Accounting for Uncertainty in Income Taxes . A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that has a likelihood greater than 50% of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. Derivatives All derivative instruments are recorded at fair value. If derivative instruments are designated as hedges of fair values, both the change in the fair value of the hedge and the hedged item are included in current earnings. Fair value adjustments related to cash flow hedges, if any, are recorded in other comprehensive income or loss and reclassified to earnings when the hedged transaction is reflected in earnings. Comprehensive Income or Loss Comprehensive income or loss consists of net income and other comprehensive income or loss. Other comprehensive income or loss includes unrealized gains and losses on securities available-for-sale, net of tax, which are also recognized as separate components of shareholders’ equity. EPS Basic EPS is net income divided by the weighted average number of common shares outstanding during the period less average unvested RSAs. Diluted EPS includes the dilutive effect of additional potential common shares related to unvested RSAs using the treasury stock method. During the years ended December 31, 2023 and 2022, there were no outstanding stock options. The Company has two forms of outstanding common stock: common stock and unvested RSAs. Holders of unvested RSAs receive non-forfeitable dividends at the same rate as common shareholders and they both share equally in undistributed earnings, and therefore the RSAs are considered participating securities. However, under the two-class method, the difference in EPS is not significant for these participating securities. (in thousands, except share and per share data) 2023 2022 Net income $ 47,734 $ 44,801 Weighted average basic common shares outstanding 17,166,592 17,128,282 Add: Dilutive effects of assumed vesting of restricted stock 21,377 37,328 Weighted average diluted common shares outstanding 17,187,969 17,165,610 Income per common share: Basic EPS $ 2.78 $ 2.61 Diluted EPS $ 2.78 $ 2.61 Anti-dilutive shares, which are excluded from the dilutive EPS calculation, were deemed to be immaterial. Subordinated Notes The subordinated notes are recorded at par with related debt issuance costs reported as a direct reduction from the carrying amount. Issuance costs are amortized over the remaining maturity of the notes and reflected in interest expense. Fair Value of Financial Instruments The consolidated financial statements include various estimated fair value information as of December 31, 2023 and 2022. Such information, which pertains to the Company’s financial instruments, does not purport to represent the aggregate net fair value of the Company. Further, the fair value estimates are based on various assumptions, methodologies, and subjective considerations, which vary widely among different financial institutions, and are subject to change. Fair Value Measurements The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The Company bases the fair values on 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. Securities available-for-sale and derivatives, if any, are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record certain assets at fair value on a non-recurring basis, such as loans held for sale and certain collateral dependent impaired loans held for investment. These non-recurring fair value adjustments typically involve write-downs of individual assets due to application of lower of cost or fair value accounting. Accounting standards require the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: Level 1 : Quoted prices (unadjusted) for identical assets or liabilities in active markets that the Company has the ability to access as of the measurement date. Level 2 : Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 : Significant unobservable inputs that reflect the Company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. T

Accounting Changes and Error Corrections [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards The following reflects recent accounting standards that have been adopted or are pending adoption by the Company. As discussed in Note 1, Basis of Presentation, the Company qualifies as an emerging growth company and as such, has elected to use the extended transition period for complying with new or revised accounting standards and is not subject to the new or revised accounting standards applicable to public companies during the extended transition period. The accounting standards discussed below indicate effective dates for the Company as an emerging growth company with the extended transition period. Accounting Standards Adopted On January 1, 2023, the Company adopted ASC 326, which replaces the current “incurred loss” model for recognizing credit losses with an “expected loss” model referred to as the CECL model. The CECL model applies to estimated credit losses on loans receivable, held-to-maturity debt securities, unfunded loan commitments, and certain other financial assets measured at amortized cost. Under ASC 326, available-for-sale debt securities are evaluated for impairment if fair value is less than amortized cost, with any estimated credit losses recorded through a credit loss expense and an allowance, rather than a write-down of the investment. Changes in fair value that are not credit-related will continue to be recorded in other comprehensive income. The Company adopted this standard using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance was effective for financial assets measured at amortized cost. For certain new disclosures required under ASC 326, such as credit quality indicators by year of origination, the Company has not restated comparative financial information before January 1, 2023 to conform under ASC 326. This adoption method is considered a change in accounting principle requiring additional disclosure of the nature and reason for the change, which is solely due to adoption of ASC 326. On January 1, 2023, the Company also adopted ASU No. 2022-02, Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, which had no material impact. The following table reflects the cumulative-effect adjustments the Company recorded on January 1, 2023 for the adoption of ASC 326. January 1, 2023 (in thousands) Pre-ASC 326 Adoption Impact of ASC 326 Adoption Post-ASC 326 Adoption Assets: Allowance for Credit Losses - Loans $ (28,389) $ (5,262) $ (33,651) Allowance for Credit Losses - HTM Securities — (20) (20) Deferred Tax Asset (Interest receivable and other assets) 12,273 1,883 14,156 Liabilities: Reserve for Unfunded Commitments (Interest payable and other liabilities) (125) (1,092) (1,217) Shareholders’ Equity: Retained Earnings (46,736) 4,491 (42,245) Accounting Standards Issued But Not Yet Adopted In October 2023, the FASB issued ASU No. 2023-06, Disclosure Improvements (“ASU 2023-06”), amending disclosure or presentation requirements related to various subtopics in the FASB Accounting Standards Codification (the “Codification”). ASU 2023-06 was issued in response to the SEC’s initiative to update and simplify disclosure requirements. The SEC identified 27 disclosure requirements that were incremental to those in the Codification and referred them to the FASB for potential incorporation into U.S. GAAP. To avoid duplication, the SEC intended to eliminate those disclosure requirements from existing SEC regulations as the FASB incorporated them into the relevant Codification subtopics. ASU 2023-06 adds 14 of the 27 identified disclosure or presentation requirements to the Codification. ASU 2023-06 is to be applied prospectively, and early adoption is prohibited. For reporting entities subject to the SEC’s existing disclosure requirements, the effective dates of ASU 2023-06 will be the date on which the SEC’s removal of that related disclosure requirement from Regulation S-X or Regulation S-K becomes effective. If by June 30, 2027, the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the related amendment will be removed from the Codification and will not become effective for any entities. ASU 2023-06 is not expected to have a significant impact on the Company's consolidated financial statements. In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280) - Improvement to Reportable Segment Disclosures (“ASU 2023-07”), amending disclosure requirements related to segment reporting primarily through enhanced disclosure about significant segment expenses and by requiring disclosure of segment information on an annual and interim basis. ASU 2023-07 is effective January 1, 2024 and is not expected to have a significant impact on the Company's consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures (“ASU 2023-09”), which enhances the transparency and decision usefulness of income tax disclosures. ASU 2023-09 will require disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. Entities will also be required to disclose income/(loss) from continuing operations before income tax expense/(benefit) disaggregated between domestic and foreign, as well as income tax expense/(benefit) from continuing operations disaggregated by federal, state and foreign. ASU 2023-09 is effective January 1, 2025 and is not expected to have a significant impact on the Company's consolidated financial statements.

As of December 31, 2023, the investment portfolio included 146 investment securities that had been in a continuous loss position for twelve months or more and three investment securities that had been in a loss position for less than twelve months. There was one held-to-maturity security in a continuous unrealized loss position at December 31, 2023, which had been in a continuous loss position for more than twelve months. Obligations issued or guaranteed by government agencies such as the Government National Mortgage Association and the SBA or GSEs under conservatorship such as the FNMA and the FHLMC, are guaranteed or sponsored by agencies of the U.S. government and have strong credit profiles. The Company therefore expects to receive all contractual interest payments on time and believes the risk of credit losses on these securities is remote. The Company’s investment in obligations of states and political subdivisions are deemed credit worthy after management’s comprehensive analysis of the issuers’ latest financial information, credit ratings by major credit agencies, and/or credit enhancements. Non-Marketable Securities Included in Other Assets FHLB capital stock : As a member of the FHLB, the Company is required to maintain a minimum investment in FHLB capital stock determined by the board of directors of the FHLB. The minimum investment requirements can increase in the event the Company increases its total asset size or borrowings with the FHLB. Shares cannot be purchased or sold except between the FHLB and its members at the $100 per share par value. The Company held $15,000,000 and $10,890,000 of FHLB stock at December 31, 2023 and 2022, respectively. The carrying amounts of these investments are reasonable estimates of fair value because the securities are restricted to member banks and do not have a readily determinable market value. Based on management’s analysis of the FHLB’s financial condition and certain qualitative factors, management determined that the FHLB stock was not impaired at December 31, 2023 and 2022. For the years ended December 31, 2023 and 2022, cash dividends received on FHLB capital stock in the amount of $970,000 and $546,000, respectively, were recorded as non-interest income in the consolidated statements of income.

Receivables [Abstract]
Loans and Allowance for Credit Losses	Loans and Allowance for Credit Losses The Company’s loan portfolio is its largest class of earning assets and typically provides higher yields than other types of earning assets. Associated with the higher yields is an inherent amount of credit risk which the Company attempts to mitigate through strong underwriting practices. The following table presents the balance of each major product type within the Company’s portfolio as of the dates indicated. (in thousands) 2023 2022 Real estate: Commercial $ 2,685,419 $ 2,394,674 Commercial land and development 15,551 7,477 Commercial construction 62,863 88,669 Residential construction 15,456 6,693 Residential 25,893 24,230 Farmland 51,669 52,478 Commercial: Secured 165,109 165,186 Unsecured 23,850 25,431 Consumer and other 38,166 28,628 Subtotal 3,083,976 2,793,466 Net deferred loan fees (2,257) (2,140) Allowance for credit losses - loans (34,431) (28,389) Loans held for investment, net of allowance for credit losses $ 3,047,288 $ 2,762,937 Underwriting Commercial loans : Commercial loans are underwritten after evaluating and understanding the borrower’s ability to operate profitably and prudently expand its business. Underwriting standards are designed to promote relationship banking rather than transactional banking. Once it is determined that the borrower’s management possesses sound ethics and solid business acumen, the Company’s management examines current and projected cash flows to determine the ability of the borrower to repay its obligations as agreed. Commercial loans are primarily made based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected, and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some short-term loans may be made on an unsecured basis. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers. Real estate loans : Real estate loans are subject to underwriting standards and processes similar to commercial loans. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts, and the repayment of these loans is generally largely dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Commercial real estate loans may be more adversely affected than other loans by conditions in the real estate market or in the general economy. The properties securing the Company’s commercial real estate portfolio are diverse in terms of type. This diversity helps reduce the Company’s exposure to adverse economic events that affect any single market or industry. Management monitors and evaluates commercial real estate loans based on collateral, geography, and risk grade criteria. Construction loans : With respect to construction loans that the Company may originate from time to time, the Company generally requires the borrower to have had an existing relationship with the Company and have a proven record of success. Construction loans are underwritten utilizing feasibility studies, independent appraisal reviews, sensitivity analysis of absorption and lease rates, and financial analysis of the developers and property owners. Construction loans are generally based upon estimates of costs and value associated with the completed project. These estimates may be inaccurate. Construction loans often involve the disbursement of substantial funds with repayment substantially dependent on the ultimate success of the project. Sources of repayment for these types of loans may be pre-committed permanent loans from approved long-term lenders, sales of developed property, or an interim loan commitment from the Company until permanent financing is obtained. These loans are closely monitored using on-site inspections and are generally considered to have higher risks than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, governmental regulation of real property, general economic conditions, and the availability of long-term financing. Residential real estate loans : Residential real estate loans are underwritten based upon the borrower’s income, credit history, and collateral. To monitor and manage residential loan risk, policies and procedures are developed and modified, as needed. This activity, coupled with relatively small loan amounts that are spread across many individual borrowers, minimizes risk. Underwriting standards for home loans are heavily influenced by statutory requirements, which include, but are not limited to, a maximum loan-to-value percentage, collection remedies, the number of such loans a borrower can have at one time, and documentation requirements. Farmland loans : Farmland loans are generally made to producers and processors of crops and livestock. Repayment is primarily from the sale of an agricultural product or service. Farmland loans are secured by real property and are susceptible to changes in market demand for specific commodities. This may be exacerbated by, among other things, industry changes, changes in the individual financial capacity of the business owner, general economic conditions, and changes in business cycles, as well as adverse weather conditions. Consumer loans : The Company purchased consumer loans underwritten utilizing credit scoring analysis to supplement the underwriting process. To monitor and manage consumer loan risk, policies and procedures are developed and modified, as needed. This activity, coupled with relatively small loan amounts that are spread across many individual borrowers, minimizes risk. Underwriting standards for home equity loans are heavily influenced by statutory requirements, which include, but are not limited to, a maximum loan-to-value percentage, collection remedies, the number of such loans a borrower can have at one time, and documentation requirements. Concentrations The Company’s customers are primarily located in the Greater Sacramento and North Valley regions of California. As of December 31, 2023, approximately 93% of the Company’s loans were real estate related, 6% were commercial, and 1% were consumer. Credit Quality Indicators The Company has established a loan risk rating system to measure and monitor the quality of the loan portfolio. All loans are assigned a risk rating from the inception of the loan until the loan is paid off. The primary loan grades are as follows: Loans rated pass : These are loans to borrowers with satisfactory financial support, repayment capacity, and credit strength. Borrowers in this category demonstrate fundamentally sound financial positions, repayment capacity, credit history, and management expertise. Loans in this category must have an identifiable and stable source of repayment and meet the Company’s policy regarding debt service coverage ratios. These borrowers are capable of sustaining normal economic, market, or operational setbacks without significant financial impacts and their financial ratios and trends are acceptable. Negative external industry factors are generally not present. The loan may be secured, unsecured, or supported by non-real estate collateral for which the value is more difficult to determine and/or marketability is more uncertain. Loans rated watch : These are loans which have deficient loan quality and potentially significant issues, but losses do not appear to be imminent, and the issues are expected to be temporary in nature. The significant issues are typically: (i) a history of losses or events that threaten the borrower’s viability; (ii) a property with significant depreciation and/or marketability concerns; or (iii) poor or deteriorating credit, occasional late payments, and/or limited reserves but the loan is generally kept current. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Loans rated substandard : These are loans which are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged (if any). Loans so classified exhibit a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Loans are characterized by the distinct possibility that the Company may sustain some loss if the deficiencies are not corrected. Loans rated doubtful : These are loans for which the collection or liquidation of the entire debt is highly questionable or improbable. Typically, the possibility of loss is extremely high. The losses on these loans are deferred until all pending factors have been addressed. The amortized cost basis of the Company’s loans by origination year, where origination is defined as the later of origination or renewal date, and credit quality indicator as of December 31, 2023 was as follows (disclosure not comparative due to adoption of ASC 326 on January 1, 2023 – refer to Note 1, Basis of Presentation, for further details): Amortized Cost Basis by Origination Year (in thousands) 2023 2022 2021 2020 2019 Prior Revolving Loans Revolving Converted to Term Total Real estate: Commercial Pass $ 329,876 $ 992,181 $ 714,965 $ 238,655 $ 128,424 $ 247,030 $ 4,685 $ — $ 2,655,816 Watch — 8,534 6,274 4,727 574 4,896 — — 25,005 Substandard — — — — — 1,890 — — 1,890 Doubtful — — — — — — — — — Total 329,876 1,000,715 721,239 243,382 128,998 253,816 4,685 — 2,682,711 Commercial land and development Pass 11,388 3,229 — 184 — 733 — — 15,534 Watch — — — — — — — — — Substandard — — — — — — — — — Doubtful — — — — — — — — — Total 11,388 3,229 — 184 — 733 — — 15,534 Commercial construction Pass 9,074 32,154 4,189 11,230 — 5,897 — — 62,544 Watch — — — — — — — — — Substandard — — — — — — — — — Doubtful — — — — — — — — — Total 9,074 32,154 4,189 11,230 — 5,897 — — 62,544 Residential construction Pass 2,412 9,128 3,912 — — — — — 15,452 Watch — — — — — — — — — Substandard — — — — — — — — — Doubtful — — — — — — — — — Total 2,412 9,128 3,912 — — — — — 15,452 Amortized Cost Basis by Origination Year (in thousands) 2023 2022 2021 2020 2019 Prior Revolving Loans Revolving Converted to Term Total Real estate: Residential Pass 4,838 3,964 6,244 2,279 1,182 5,995 1,420 — 25,922 Watch — — — — — — — — — Substandard — — — — — — — — — Doubtful — — — — — — — — — Total 4,838 3,964 6,244 2,279 1,182 5,995 1,420 — 25,922 Farmland Pass 2,311 8,037 12,678 7,860 12,365 8,391 4 — 51,646 Watch — — — — — — — — — Substandard — — — — — — — — — Doubtful — — — — — — — — — Total 2,311 8,037 12,678 7,860 12,365 8,391 4 — 51,646 Commercial: Secured Pass 25,299 28,879 14,304 12,164 9,918 10,363 50,020 — 150,947 Watch 189 8,802 2,705 63 154 941 1,727 — 14,581 Substandard — — — — 45 27 — — 72 Doubtful — — — — — — — — — Total 25,488 37,681 17,009 12,227 10,117 11,331 51,747 — 165,600 Unsecured Pass 3,891 3,782 4,902 5,963 2,240 7 3,072 — 23,857 Watch — — — — — — — — — Substandard — — — — — — — — — Doubtful — — — — — — — — — Total 3,891 3,782 4,902 5,963 2,240 7 3,072 — 23,857 Consumer and other Pass 18,489 11,359 8,264 6 — 307 — — 38,425 Watch — 16 — — — — — — 16 Substandard — 12 — — — — — — 12 Doubtful — — — — — — — — — Total 18,489 11,387 8,264 6 — 307 — — 38,453 Total Pass 407,578 1,092,713 769,458 278,341 154,129 278,723 59,201 — 3,040,143 Watch 189 17,352 8,979 4,790 728 5,837 1,727 — 39,602 Substandard — 12 — — 45 1,917 — — 1,974 Doubtful — — — — — — — — — Total $ 407,767 $ 1,110,077 $ 778,437 $ 283,131 $ 154,902 $ 286,477 $ 60,928 $ — $ 3,081,719 Management regularly reviews the Company’s loans for accuracy of risk grades whenever new information is received. Borrowers are generally required to submit financial information at regular intervals. Typically, commercial borrowers with lines of credit are required to submit financial information with reporting intervals ranging from monthly to annually depending on credit size, risk, and complexity. In addition, investor commercial real estate borrowers with loans exceeding a certain dollar threshold are usually required to submit rent rolls or property income statements annually. Management monitors construction loans monthly and reviews consumer loans based on delinquency. Management also reviews loans graded “watch” or worse, regardless of loan type, no less than quarterly.

In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers. Real estate loans : Real estate loans are subject to underwriting standards and processes similar to commercial loans. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts, and the repayment of these loans is generally largely dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Commercial real estate loans may be more adversely affected than other loans by conditions in the real estate market or in the general economy. The properties securing the Company’s commercial real estate portfolio are diverse in terms of type. This diversity helps reduce the Company’s exposure to adverse economic events that affect any single market or industry. Management monitors and evaluates commercial real estate loans based on collateral, geography, and risk grade criteria. Construction loans : With respect to construction loans that the Company may originate from time to time, the Company generally requires the borrower to have had an existing relationship with the Company and have a proven record of success. Construction loans are underwritten utilizing feasibility studies, independent appraisal reviews, sensitivity analysis of absorption and lease rates, and financial analysis of the developers and property owners. Construction loans are generally based upon estimates of costs and value associated with the completed project. These estimates may be inaccurate. Construction loans often involve the disbursement of substantial funds with repayment substantially dependent on the ultimate success of the project. Sources of repayment for these types of loans may be pre-committed permanent loans from approved long-term lenders, sales of developed property, or an interim loan commitment from the Company until permanent financing is obtained. These loans are closely monitored using on-site inspections and are generally considered to have higher risks than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, governmental regulation of real property, general economic conditions, and the availability of long-term financing. Residential real estate loans : Residential real estate loans are underwritten based upon the borrower’s income, credit history, and collateral. To monitor and manage residential loan risk, policies and procedures are developed and modified, as needed. This activity, coupled with relatively small loan amounts that are spread across many individual borrowers, minimizes risk. Underwriting standards for home loans are heavily influenced by statutory requirements, which include, but are not limited to, a maximum loan-to-value percentage, collection remedies, the number of such loans a borrower can have at one time, and documentation requirements. Farmland loans : Farmland loans are generally made to producers and processors of crops and livestock. Repayment is primarily from the sale of an agricultural product or service. Farmland loans are secured by real property and are susceptible to changes in market demand for specific commodities. This may be exacerbated by, among other things, industry changes, changes in the individual financial capacity of the business owner, general economic conditions, and changes in business cycles, as well as adverse weather conditions. Consumer loans : The Company purchased consumer loans underwritten utilizing credit scoring analysis to supplement the underwriting process. To monitor and manage consumer loan risk, policies and procedures are developed and modified, as needed. This activity, coupled with relatively small loan amounts that are spread across many individual borrowers, minimizes risk. Underwriting standards for home equity loans are heavily influenced by statutory requirements, which include, but are not limited to, a maximum loan-to-value percentage, collection remedies, the number of such loans a borrower can have at one time, and documentation requirements. Concentrations The Company’s customers are primarily located in the Greater Sacramento and North Valley regions of California. As of December 31, 2023, approximately 93% of the Company’s loans were real estate related, 6% were commercial, and 1% were consumer. Credit Quality Indicators The Company has established a loan risk rating system to measure and monitor the quality of the loan portfolio. All loans are assigned a risk rating from the inception of the loan until the loan is paid off. The primary loan grades are as follows: Loans rated pass : These are loans to borrowers with satisfactory financial support, repayment capacity, and credit strength. Borrowers in this category demonstrate fundamentally sound financial positions, repayment capacity, credit history, and management expertise. Loans in this category must have an identifiable and stable source of repayment and meet the Company’s policy regarding debt service coverage ratios. These borrowers are capable of sustaining normal economic, market, or operational setbacks without significant financial impacts and their financial ratios and trends are acceptable. Negative external industry factors are generally not present. The loan may be secured, unsecured, or supported by non-real estate collateral for which the value is more difficult to determine and/or marketability is more uncertain. Loans rated watch : These are loans which have deficient loan quality and potentially significant issues, but losses do not appear to be imminent, and the issues are expected to be temporary in nature. The significant issues are typically: (i) a history of losses or events that threaten the borrower’s viability; (ii) a property with significant depreciation and/or marketability concerns; or (iii) poor or deteriorating credit, occasional late payments, and/or limited reserves but the loan is generally kept current. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Loans rated substandard : These are loans which are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged (if any). Loans so classified exhibit a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Loans are characterized by the distinct possibility that the Company may sustain some loss if the deficiencies are not corrected. Loans rated doubtful : These are loans for which the collection or liquidation of the entire debt is highly questionable or improbable. Typically, the possibility of loss is extremely high. The losses on these loans are deferred until all pending factors have been addressed. The amortized cost basis of the Company’s loans by origination year, where origination is defined as the later of origination or renewal date, and credit quality indicator as of December 31, 2023 was as follows (disclosure not comparative due to adoption of ASC 326 on January 1, 2023 – refer to Note 1, Basis of Presentation, for further details): Amortized Cost Basis by Origination Year (in thousands) 2023 2022 2021 2020 2019 Prior Revolving Loans Revolving Converted to Term Total Real estate: Commercial Pass $ 329,876 $ 992,181 $ 714,965 $ 238,655 $ 128,424 $ 247,030 $ 4,685 $ — $ 2,655,816 Watch — 8,534 6,274 4,727 574 4,896 — — 25,005 Substandard — — — — — 1,890 — — 1,890 Doubtful — — — — — — — — — Total 329,876 1,000,715 721,239 243,382 128,998 253,816 4,685 — 2,682,711 Commercial land and development Pass 11,388 3,229 — 184 — 733 — — 15,534 Watch — — — — — — — — — Substandard — — — — — — — — — Doubtful — — — — — — — — — Total 11,388 3,229 — 184 — 733 — — 15,534 Commercial construction Pass 9,074 32,154 4,189 11,230 — 5,897 — — 62,544 Watch — — — — — — — — — Substandard — — — — — — — — — Doubtful — — — — — — — — — Total 9,074 32,154 4,189 11,230 — 5,897 — — 62,544 Residential construction Pass 2,412 9,128 3,912 — — — — — 15,452 Watch — — — — — — — — — Substandard — — — — — — — — — Doubtful — — — — — — — — — Total 2,412 9,128 3,912 — — — — — 15,452 Amortized Cost Basis by Origination Year (in thousands) 2023 2022 2021 2020 2019 Prior Revolving Loans Revolving Converted to Term Total Real estate: Residential Pass 4,838 3,964 6,244 2,279 1,182 5,995 1,420 — 25,922 Watch — — — — — — — — — Substandard — — — — — — — — — Doubtful — — — — — — — — — Total 4,838 3,964 6,244 2,279 1,182 5,995 1,420 — 25,922 Farmland Pass 2,311 8,037 12,678 7,860 12,365 8,391 4 — 51,646 Watch — — — — — — — — — Substandard — — — — — — — — — Doubtful — — — — — — — — — Total 2,311 8,037 12,678 7,860 12,365 8,391 4 — 51,646 Commercial: Secured Pass 25,299 28,879 14,304 12,164 9,918 10,363 50,020 — 150,947 Watch 189 8,802 2,705 63 154 941 1,727 — 14,581 Substandard — — — — 45 27 — — 72 Doubtful — — — — — — — — — Total 25,488 37,681 17,009 12,227 10,117 11,331 51,747 — 165,600 Unsecured Pass 3,891 3,782 4,902 5,963 2,240 7 3,072 — 23,857 Watch — — — — — — — — — Substandard — — — — — — — — — Doubtful — — — — — — — — — Total 3,891 3,782 4,902 5,963 2,240 7 3,072 — 23,857 Consumer and other Pass 18,489 11,359 8,264 6 — 307 — — 38,425 Watch — 16 — — — — — — 16 Substandard — 12 — — — — — — 12 Doubtful — — — — — — — — — Total 18,489 11,387 8,264 6 — 307 — — 38,453 Total Pass 407,578 1,092,713 769,458 278,341 154,129 278,723 59,201 — 3,040,143 Watch 189 17,352 8,979 4,790 728 5,837 1,727 — 39,602 Substandard — 12 — — 45 1,917 — — 1,974 Doubtful — — — — — — — — — Total $ 407,767 $ 1,110,077 $ 778,437 $ 283,131 $ 154,902 $ 286,477 $ 60,928 $ — $ 3,081,719 Management regularly reviews the Company’s loans for accuracy of risk grades whenever new information is received.

The notes will be used for capital management and general corporate purposes, including, without limitation, the redemption of existing subordinated notes. The subordinated notes have a maturity date of September 1, 2032 and bear interest, payable semi-annually, at the rate of 6.00% per annum until September 1, 2027. On that date, the interest rate will be adjusted to float at a rate equal to the three-month Term SOFR plus 329.0 basis points (8.62% as of December 31, 2023) until maturity. The notes include a right of prepayment, on or after August 17, 2027 or, in certain limited circumstances, before that date.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions During the normal course of business, the Company may enter into transactions with related parties, including directors, executive officers, principal shareholders, and their businesses or affiliates. In accordance with applicable regulations and Bank policies, these loans are granted on substantially the same terms, including interest rates and collateral on loans, as those prevailing at the same time for comparable transactions with persons not related to the Company. Likewise, these transactions do not involve more than the normal risk of collectability or present other unfavorable features. The following is a summary of loans to related parties in 2023 and 2022: (in thousands) 2023 2022 Beginning balance $ 6,250 $ 9,418 New loans or advances 1,275 340 Repayments (2,070) (3,146) Transfers out 1 — (362) Ending balance $ 5,455 $ 6,250 1 As a result of a change in employment with the Company, a loan balance belonging to a previously related party was transferred out of the classification of related party loans. The change was not the result of any disagreement with the Company or due to any matter relating to its operations, policies, or practices. At December 31, 2023 and 2022, deposits from related parties (directors, executive officers, and principal shareholders) totaled $37,201,000 and $51,960,000, respectively. The Company leases an administrative office from a partnership comprised of certain shareholders and members of the board of directors, which is further described in Note 15, Commitments and Contingencies. Property management fees totaling $1,000 in 2023 and 2022 were paid to the entity that owns this property.

Retirement Benefits [Abstract]
Equity Incentive Plan	Equity Incentive Plan In April 2021, the Company’s board of directors and shareholders approved the Five Star Bancorp 2021 Equity Incentive Plan (the “Equity Incentive Plan”). The Equity Incentive Plan provides for the grant of stock options, stock appreciation rights, performance awards, restricted stock, restricted stock units, and other stock-based awards that the Compensation Committee determines are consistent with the purpose of the Equity Incentive Plan and the interests of the Company. Awards may be granted to the Company’s executives and other key employees, directors, and other service providers and are designed to align the interests of the Equity Incentive Plan’s participants with the interests of the Company’s shareholders. The stock options granted under the Equity Incentive Plan may be either non-statutory stock options or incentive stock options. There were no stock options outstanding at December 31, 2023 or 2022, respectively. The total number of shares of the Company’s common stock reserved and available for grant and issuance pursuant to the Equity Incentive Plan will not exceed 1,700,000 shares, less RSAs granted, plus any RSAs that become available upon forfeiture. Each of these shares may be issued as an incentive stock option. At December 31, 2023, 1,504,761 shares remained available for issuance pursuant to grant awards under the Plan. The Equity Incentive Plan does not contain an “evergreen” provision pursuant to which shares authorized for issuance may be automatically replenished. Stock-Based Compensation The Company’s stock-based compensation consists of RSAs granted under its historical stock-based incentive arrangement (the “Historical Incentive Plan”) and RSAs issued under the Equity Incentive Plan. The Historical Incentive Plan consisted of RSAs for certain executive officers of the Company. The arrangement provided that these executive officers would receive shares of restricted common stock of the Company that vested over three years, with the number of shares granted based upon achieving certain performance objectives. These objectives included, but were not limited to, net income adjusted for the provision for credit losses, deposit growth, efficiency ratio, net interest margin, and asset quality. Compensation expense for RSAs granted under the Historical Incentive Plan is recognized over the service period, which is equal to the vesting period of the shares based on the fair value of the shares at issue date. In connection with its IPO in May 2021, the Company granted RSAs under the Equity Incentive Plan to certain employees, officers, executives, and non-employee directors. Shares granted to non-employee directors vested immediately upon grant, while shares granted to certain employees, officers, and executives vest ratably over three five Non-cash stock compensation expense recognized for the years ended December 31, 2023 and 2022 was $962,000 and $1,099,000, respectively. In 2023, the Company granted as compensation to members of the board of directors a total of 13,882 shares scheduled to cliff vest as of December 31, 2023 contingent on continued service. In 2022, the Company granted as compensation to members of the board of directors a total of 15,156 shares scheduled to vest monthly in equal installments over one year contingent on continued service. As of December 31, 2023, there was approximately $1,103,000 of unrecognized compensation expense related to the 69,338 unvested restricted shares. The holders of unvested RSAs are entitled to dividends at the same per-share ratio as holders of common stock. Tax benefits for dividends paid on unvested RSAs are recorded as tax benefits in the consolidated statements of income with a corresponding decrease to current taxes payable. Such tax benefits are expected to be recognized over the weighted average term remaining on the unvested restricted shares of 2.88 years as of December 31, 2023. The impact of tax benefits for dividends paid on unvested restricted stock on the Company’s consolidated statements of income for the years ended December 31, 2023 and 2022 was immaterial. The following table summarizes information about unvested restricted shares: 2023 2022 Shares Weighted Average Grant Date Fair Value Shares Weighted Average Grant Date Fair Value Beginning of the period balance 96,826 $ 20.34 127,751 $ 19.95 Shares granted 16,978 28.52 23,639 28.29 Shares vested (42,553) 23.07 (48,003) 23.07 Shares forfeited (1,913) 25.62 (6,561) 21.29 End of the period balance 69,338 $ 20.53 96,826 $ 20.34

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Financial Instruments with Off-Balance Sheet Risk Some financial instruments, such as loan commitments, credit lines, letters of credit, and overdraft protection, are issued to meet customer financing needs. These are agreements to provide credit or to support the credit of others, as long as conditions established in the contract are met, and usually have expiration dates. Commitments may expire without being used. Substantially all of these commitments are at variable interest rates, based on an index, and have fixed expiration dates. Off-balance sheet risk to credit loss exists up to the face amount of these instruments, although material losses are not anticipated. The Company uses the same credit policies in making commitments to originate loans and lines of credit as it does for on-balance sheet instruments, including obtaining collateral at exercise of the commitment. The contractual amounts of unfunded loan commitments and standby letters of credit not reflected in the consolidated balance sheets were as follows: (in thousands) 2023 2022 Commercial lines of credit $ 181,855 $ 147,021 Undisbursed commercial real estate loans 107,712 79,121 Undisbursed construction loans 134,828 80,726 Agricultural lines of credit 24,635 10,399 Undisbursed residential real estate loans 6,538 8,945 Undisbursed agricultural real estate loans 1,200 1,068 Other 2,119 1,868 Total commitments and standby letters of credit $ 458,887 $ 329,148 The Company records an allowance for credit losses on unfunded loan commitments at the consolidated balance sheet date based on estimates of the probability that these commitments will be drawn upon according to historical utilization experience of the different types of commitments and historical loss rates determined for pooled funded loans. The allowance for credit losses on unfunded commitments totaled $1,247,000 and $125,000 as of December 31, 2023 and 2022, respectively, which is recorded in “Interest payable and other liabilities” in the consolidated balance sheets. Concentrations of credit risk : The Company grants real estate mortgage, real estate construction, commercial, and consumer loans to customers primarily in Northern California. Although the Company has a diversified loan portfolio, a substantial portion is secured by commercial and residential real estate. In management’s judgment, a concentration of loans exists in real estate related loans, which represented approximately 92.30% of the Company’s loan portfolio at December 31, 2023 and 91.84% of the Company’s loan portfolio at December 31, 2022. Although management believes such concentrations have no more than the normal risk of collectability, a substantial decline in the economy in general, or a decline in real estate values in the Company’s primary market areas in particular, could have an adverse impact on the collectability of these loans. Personal and business incomes represent the primary source of repayment for the majority of these loans. Deposit concentrations : At December 31, 2023, the Company had 93 deposit relationships that exceeded $5,000,000 each, totaling $1,867,267,000, or approximately 61.69% of total deposits. The Company’s largest single deposit relationship at December 31, 2023 totaled $260,000,000, or approximately 8.59% of total deposits. Management maintains the Company’s liquidity position and lines of credit with correspondent banks to mitigate the risk of large withdrawals by this group of large depositors. Correspondent banking agreements : The Company maintains funds on deposit with other FDIC-insured financial institutions under correspondent banking agreements. Uninsured deposits through these agreements totaled $22,348,000 and $16,163,000 at December 31, 2023 and 2022, respectively. Leases The Company leases office space for its banking operations under non-cancelable operating leases of various terms. The leases expire at dates through 2032 and provide for renewal options from less than one The Company has a sublease agreement for space adjacent to the Redding location. The sublease has renewal terms extended to December 31, 2024. The Company leases its Sacramento administrative office from a partnership comprised of certain shareholders and members of the Company’s board of directors. The Sacramento administrative office lease extends through May 2026. Rent expense paid to the partnership was $28,000 and $30,000 for the years ended December 31, 2023 and 2022, respectively, under this lease. The Company leases a temporary administrative office in San Francisco from an entity affiliated with a member of our board of directors. Rent expense paid to this entity was $19,000 for the year ended December 31, 2023. The Company adopted ASU 2016-02, Leases (Topic 842) as of January 1, 2022, which requires the Company to record an ROUA in the consolidated balance sheets for those leases that convey rights to control use of identified assets for a period of time in exchange for consideration. The Company is also required to record a lease liability in the consolidated balance sheets for the present value of future payment commitments. All of the Company’s leases are comprised of operating leases in which the Company is the lessee of real estate property for branches and operations. The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less) within the ROUA and lease liability. Known or determinable adjustments to the required minimum future lease payments were included in the calculation of the Company’s ROUA and lease liability. Adjustments to the required minimum future lease payments that are variable and will not be determinable until a future period, if any, are included as variable lease costs. Additionally, expected variable payments for common area maintenance, taxes, and insurance were unknown and not determinable at lease commencement and, therefore, were not included in the determination of the Company’s ROUA and lease liability. The value of the ROUA and lease liability is impacted by the amount of the periodic payment required, length of the lease term, and the discount rate used to calculate the present value of the minimum lease payments. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROUA and lease liability. ASC 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. For operating leases existing prior to January 1, 2022, the rate for the remaining lease term as of January 1, 2022 was used. The lease liability is reduced based on the discounted present value of remaining payments as of each reporting period. The ROUA value is measured using the lease liability as adjusted for prepaid or accrued lease payments and remaining lease incentives, unamortized direct costs, and impairment, if any. As of December 31, 2023, the Company’s ROUA and lease liability were $5,284,000 and $5,603,000, respectively. The following table presents the components of lease expense for the year ended December 31, 2023: (in thousands) Twelve months ended December 31, 2023 Operating lease expense $ 1,261 Sublease income (22) Total lease expense $ 1,239 The following table presents the weighted average operating lease term and discount rate at December 31, 2023: December 31, 2023 Weighted average remaining lease term 5.28 years Weighted average discount rate 4.11 % The following table shows the future minimum lease payments under the Company’s operating lease arrangements as of December 31, 2023.

In the opinion of management, the amount of ultimate liability with respect to such actions will not materially affect the consolidated financial position or results of operations of the Company.

Capital Requirements and Restri

Capital Requirements and Restrictions on Retained Earnings	12 Months Ended

Banking Regulation, Risk-Based Information [Abstract]
Capital Requirements and Restrictions on Retained Earnings	Capital Requirements and Restrictions on Retained Earnings The Company and the Bank are subject to various regulatory capital requirements administered by federal and state banking agencies. Failure to meet minimum capital requirements as set forth in the following tables can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and the Bank’s prompt corrective action classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Prompt corrective action provisions are generally not applicable to bank holding companies. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the below table) of total capital, Tier 1 capital, and common equity Tier 1 capital (as defined in the regulations) to risk-weighted assets and of Tier 1 capital to average assets. Historically, as a bank holding company with less than $3.0 billion in total consolidated assets and that met certain other criteria, the Company had been operating under the Small Bank Holding Company Policy Statement, which provides an exemption from the Federal Reserve’s generally applicable risk-based capital ratio and leverage ratio requirements. Having passed this threshold as of September 30, 2022, the Company is no longer subject to this policy statement and its capital adequacy is evaluated relative to the Federal Reserve’s generally applicable capital requirements. Additionally, as of June 30, 2023, the Company’s consolidated assets were in excess of $3.0 billion, 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. The Company and Bank are required to meet a common equity Tier 1 capital to risk-weighted assets ratio of at least 7.00% (a minimum of 4.50% plus a capital conservation buffer of 2.50%), a Tier 1 capital to risk-weighted assets ratio of at least 8.50% (a minimum of 6.00% plus a capital conservation buffer of 2.50%), a total capital to risk-weighted assets ratio of at least 10.50% (a minimum of 8.00% plus a capital conservation buffer of 2.50%), and a Tier 1 leverage ratio of at least 4.00%. Management believes that, as of December 31, 2023, the Company and the Bank met all capital adequacy requirements to which they are subject. As of December 31, 2023, the Bank was categorized as “well-capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well-capitalized,” an institution must maintain minimum total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the below table. There are no conditions or events since that categorization that management believes have changed the Bank’s category. The principal source of cash for the Company is dividends from the Bank. Dividends from the Bank to the Company are restricted under California law to the lesser of: (i) the Bank’s retained earnings or (ii) the Bank’s net income for the latest three fiscal years, less dividends previously declared during that period. As of December 31, 2023 and 2022, the maximum amount available for dividend distribution under this restriction was approximately $62,951,000 and $33,867,000, respectively. If a proposed dividend exceeds the limit, the Bank may still pay a dividend to the Holding Company if it obtains approval from the DFPI and the dividend does not exceed the greater of: (i) the retained earnings of the Bank; (ii) the net income of the Bank for its last fiscal year; or (iii) the net income of the Bank for its current fiscal year. The Company’s and the Bank’s actual capital amounts and ratios as of December 31, 2023 and 2022 are presented in the following tables. As of December 31, 2023 and 2022, Bancorp’s Tier 2 capital included subordinated notes, which were not included at the bank level. Eligible amounts of subordinated notes included in Tier 2 capital will be phased out by 20% per year beginning five years before the maturity date of the notes.

Fair Value Disclosures [Abstract]
Fair Value of Assets and Liabilities	Fair Value of Assets and Liabilities The following table summarizes the Company’s assets and liabilities that were required to be recorded at fair value on a recurring basis. (in thousands) Carrying Value Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Measurement Categories: Changes in Fair Value Recorded In 2023 Assets: Securities available-for-sale: U.S. government agency securities, mortgage-backed securities, obligations of states and political subdivisions, collateralized mortgage obligations, and corporate bonds $ 108,083 $ — $ 108,083 $ — OCI Derivatives – interest rate swap 10 — 10 — NI Liabilities: Derivatives – interest rate swap 10 — 10 — NI 2022 Assets: Securities available-for-sale: U.S. government agency securities, mortgage-backed securities, obligations of states and political subdivisions, collateralized mortgage obligations, and corporate bonds $ 115,988 $ — $ 115,988 $ — OCI Derivatives – interest rate swap 16 — 16 — NI Liabilities: Derivatives – interest rate swap 16 — 16 — NI Available-for-sale securities are recorded at fair value on a recurring basis. When available, quoted market prices (Level 1 inputs) are used to determine the fair value of available-for-sale securities. If quoted market prices are not available, management obtains pricing information from a reputable third-party service provider, who may utilize valuation techniques that use current market-based or independently sourced parameters, such as bid/ask prices, dealer-quoted prices, interest rates, benchmark yield curves, prepayment speeds, probability of default, loss severity, and credit spreads (Level 2 inputs). Level 2 securities include U.S. agencies’ or government-sponsored agencies’ debt securities, mortgage-backed securities, government agency-issued bonds, privately issued collateralized mortgage obligations, and corporate bonds. Level 3 securities are based on unobservable inputs that are supported by little or no market activity. In addition, values use discounted cash flow models and may include significant management judgment and estimation. As of December 31, 2023 and 2022, there were no Level 1 available-for-sale securities and no transfers between Level 1 and Level 2 classifications for assets or liabilities measured at fair value on a recurring basis. The Company’s investment portfolio service bureau has developed a model for pricing available-for-sale debt securities. Information such as historical and current performance of the underlying collateral, deferral/default rates, collateral coverage ratios, break-even yield calculations, cash flow projections, liquidity, and credit premiums required by a market participant, as well as financial trend analysis with respect to the individual issuing financial institutions and insurance companies, are utilized in determining individual security valuations. Due to current market conditions, as well as the limited trading activity of the securities, the market value of the securities is highly sensitive to assumption changes and market volatility. The Company’s derivative financial instruments are recorded at fair value, which is based on the income approach using observable Level 2 market inputs, reflecting market expectations of future interest rates as of the measurement date. Standard valuation techniques are used to calculate the present value of the future expected cash flows assuming an orderly transaction. Valuation adjustments may be made to reflect both the Company’s credit risk and the counterparties’ credit risk in determining the fair value of the derivatives. A similar credit risk adjustment, correlated to the credit standing of the counterparty, is made when collateral posted by the counterparty does not fully cover their liability to the Company. The fair value of collateral dependent impaired loans and other real estate is generally 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 appraisers to adjust for differences between the comparable sales and income data available. Management also incorporates assumptions regarding market trends or other relevant factors and selling and commission costs ranging from 5.00% to 7.00%. Such adjustments and assumptions are typically significant and result in a Level 3 classification of the inputs for determining fair value. Certain financial assets may be measured at fair value on a non-recurring basis. These assets are subject to fair value adjustments that result from the application of the lower of cost or fair value accounting or write-downs of individual assets, such as collateral dependent loans and OREO. As of December 31, 2023 and 2022, the carrying amount of assets measured at fair value on a non-recurring basis was immaterial to the Company. Disclosures about Fair Value of Financial Instruments The table below is a summary of fair value estimates for financial instruments as of December 31, 2023 and 2022. These estimates are made at a specific point in time based on relevant market data and information about the financial instruments. These estimates do not reflect any premium or discount that could result from offering the Company’s entire holdings of a particular financial instrument for sale at one time, nor do they attempt to estimate the value of anticipated future business related to the instruments. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the fair values presented. The carrying amounts in the following table are recorded in the consolidated balance sheets under the indicated captions. Further, management has not disclosed the fair value of financial instruments specifically excluded from disclosure requirements, such as BOLI.

Investment securities : See discussion above for the methods and assumptions used by the Company to estimate the fair value of investment securities. Fair value of held-to-maturity securities is estimated by calculating the net present value of future cash flows based on observable market data, such as interest rates and yield curves (observable at commonly quoted intervals) as provided by an independent third party. Loans held for sale : For loans held for sale, the fair value is based on what secondary markets are currently offering for portfolios with similar characteristics. Loans held for investment, net of allowance for credit losses : For variable rate loans that reprice frequently with no significant change in credit risk, fair values are based on carrying values. Fair values for other loans are estimated using discounted cash flow analyses, which use interest rates being offered at each reporting date for loans with similar terms to borrowers of comparable creditworthiness without considering widening credit spreads due to market illiquidity, which approximates the exit price notion. The allowance for credit losses is considered to be a reasonable estimate of loan discount for credit quality concerns. FHLB stock and other investments : Carrying amounts of these investments are reasonable estimates of fair value because the securities are restricted to member banks and do not have a readily determinable market value. Derivatives - interest rate swap : See above for a discussion of the methods and assumptions used by the Company to estimate the fair value of derivatives. FHLB advances : For FHLB advances, the carrying amount is estimated to be fair value. Commitments to extend credit : Commitments to extend credit are primarily for adjustable rate loans. For these commitments, there are no differences between the committed amounts and their fair values. Commitments to fund fixed rate loans are at rates which approximate fair value at each reporting date. Subordinated notes : The fair value is estimated by discounting the future cash flow using the current three-month CME Term SOFR. The Company’s subordinated notes are not registered securities and were issued through private placements, resulting in a Level 3 classification. The notes are recorded at carrying value.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations and Principles of Consolidation	Nature of Operations and Principles of Consolidation Five Star Bank (the “Bank”) was chartered on October 26, 1999 and began operations on December 20, 1999. Five Star Bancorp (“Bancorp” or the “Company”) was incorporated on September 16, 2002 and subsequently obtained approval from the Federal Reserve to be a bank holding company in connection with its acquisition of the Bank. The Company became the sole shareholder of the Bank on June 2, 2003 in a statutory merger, pursuant to which each outstanding share of the Bank’s common stock was exchanged for one share of common stock of the Company. The Company, through the Bank, provides a broad range of banking products and services to customers who are predominately small and medium-sized businesses, professionals, and individuals primarily in the Northern California region. The Company’s primary loan products are commercial real estate loans, land development loans, construction loans, and operating lines of credit, and its primary deposit products are checking accounts, savings accounts, money market accounts, and term certificate accounts. The Bank currently has seven branch offices in Roseville, Natomas, Rancho Cordova, Redding, Elk Grove, Chico, and Yuba City. The Company terminated its status as a Subchapter S corporation as of May 5, 2021, in connection with the Company’s IPO and became a taxable C Corporation. Prior to that date, as an S Corporation, the Company had no U.S. federal income tax expense. The Company publicly filed a Registration Statement on Form S-1 with the SEC in connection with its IPO, which was declared effective by the SEC on May 4, 2021. In connection with the IPO, the Company issued 6,054,750 shares of common stock, no par value, which included 789,750 shares sold pursuant to the underwriters’ exercise of their option to purchase additional shares. The securities were sold to the public at a price of $20.00 per share and began trading on the Nasdaq Global Select Market on May 5, 2021. On May 7, 2021, the closing date of the IPO, the Company received total net proceeds of $111,243,000. The net proceeds less other related expenses, including audit fees, legal fees, listing fees, and other expenses, totaled $109,082,000.
Basis of Financial Statement Presentation and Consolidation	Basis of Financial Statement Presentation and Consolidation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) as contained within the FASB’s ASC, including ASU, and the rules and regulations of the SEC, including the instructions to Regulation S-X. The consolidated financial statements include Bancorp and its wholly owned subsidiary, the Bank. All significant intercompany transactions and balances are eliminated in consolidation. While the Company’s chief decision-makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Discrete financial information is not available other than on a Company-wide basis. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment. The Company’s accounting and reporting policies conform to GAAP and to general practices within the banking industry. The Company qualifies as an emerging growth company as defined in the Jumpstart Our Business Startups Act of 2012, and a smaller reporting company, and, as such, may take advantage of specified reduced reporting requirements and is relieved of other significant requirements that are otherwise generally applicable to other public companies.
Use of Estimates	Use of Estimates Management is required 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions affect the amounts reported in the consolidated financial statements and the disclosures provided, and actual results could differ. The allowance for credit losses is the most significant accounting estimate reflected in the Company’s consolidated financial statements. Other estimates include fair value measurements, valuation of servicing assets, and deferred tax asset valuation.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company defines cash and cash equivalents as cash, due from financial institutions, interest-bearing deposits in banks with short-term original maturities, and federal funds sold. Generally, federal funds are sold for one-day periods, if at all. At times throughout the year, balances can exceed FDIC insurance limits. The Company has not experienced any historical losses associated with balances maintained with financial institutions in excess of FDIC insurance limits, and management continues to monitor the financial condition of the major financial institutions where these funds are held.
Securities Available-for-Sale	Securities Available-for-Sale Available-for-sale securities consist of bonds, notes, and debentures not classified as trading securities or held-to-maturity securities. Securities are classified as available-for-sale if the Company intends and has the ability to hold those securities for a period of time, but not necessarily to maturity. Any decision to sell a security classified as available-for-sale would be based on various factors, including significant movements in interest rates, changes in the maturity mix of assets and liabilities, liquidity needs, regulatory capital considerations, and other similar factors. Securities available-for-sale are carried at fair value. Unrealized holding gains or losses are included in other comprehensive income as a separate component of shareholders’ equity, net of tax. Realized gains or losses, determined based on the cost of specific securities sold, are included in earnings. Premiums are amortized over the life of the security or, if a callable bond, over the earliest call date, and discounts are accreted over the life of the related investment security as an adjustment to interest income using the effective interest method. Interest income is recognized when earned. Unrealized credit losses are recognized through an allowance for credit losses instead of an adjustment to amortized cost basis, eliminating the other-than-temporary impairment concept. For available-for-sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more likely than not that it will be required to sell, the security before recovery of amortized cost basis. If either criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through earnings. For available-for-sale debt securities that do not meet the above conditions, the Company evaluates at the individual security level whether the decrease in fair value has resulted from credit factors or non-credit factors. If assessment determines that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis of the security, then a credit loss would be recognized, limited to the amount by which the fair value is less than the amortized cost basis. All other changes in fair value of an available-for-sale debt security are recognized in other comprehensive income, net of applicable taxes. Changes in the allowance for credit losses, if any, are recognized as a provision for (or reversal of) credit losses. Accrued interest receivable is not subject to an estimate for credit loss, as the Company has a policy to charge off accrued interest deemed uncollectible in a timely manner.
Securities Held-to-Maturity	Securities Held-to-Maturity Securities are classified as held-to-maturity if the Company has both the intent and ability to hold those securities to maturity regardless of changes in market conditions, liquidity needs, or changes in general economic conditions. These securities are carried at cost adjusted for amortization of premium to the earliest callable call date and accretion of discount, computed by the effective interest method over the life of the related investment. Estimated credit losses are recorded under ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and all subsequent amendments that modified ASU 2016-13 (collectively, “ASC 326”) through a credit loss expense and an allowance. Accrued interest receivable is not subject to an estimate for credit loss, as the Company has a policy to charge off accrued interest deemed uncollectible in a timely manner.
Loans and ACL	Loans Loans are reported at the principal amount outstanding, net of deferred loan fees and costs and the allowance for credit losses - loans. Interest on loans is accrued daily based on the principal outstanding. Loan fees, net of certain direct costs of origination, are deferred and recognized in interest income using the level-yield method without anticipating prepayments. During the years ended December 31, 2023 and 2022, salaries and employee benefits totaling $3,461,000 and $6,155,000, respectively, were deferred as loan origination costs. Loans on which the accrual of interest has been discontinued are designated as non-accrual loans. Accrual of interest on loans is discontinued either when reasonable doubt exists as to the full and timely collection of interest or principal or when a loan becomes contractually past due by 90 days or more with respect to interest or principal. When a loan is placed on non-accrual status, all interest previously accrued, but not collected, is reversed against current period interest income. Income on such loans is then recognized only to the extent that cash is received and where the future collection of principal is probable. Interest accruals are resumed on such loans only when they are brought fully current with respect to interest and principal and when, in the judgment of management, the loans are estimated to be fully collectible as to both principal and interest. ACL The ACL is a valuation account that offsets the amortized cost basis of loans receivable and certain other financial assets, including unfunded loan commitments and held-to-maturity debt securities. Under ASC 326, amortized cost basis is the basis on which the ACL is determined. Amortized cost basis on loans receivable is principal outstanding, net of any purchase premiums and discounts, and net of any deferred loan fees and costs. Credit losses are charged off when management believes that the collectability of at least some portion of outstanding principal is unlikely. These charge-offs are recorded as a reversal to, thereby reducing, the allowance for credit losses. Subsequent recoveries of previously charged-off amounts, if any, are recorded as a provision to, thereby increasing, the allowance for credit losses. The allowance for credit losses is maintained at a level to absorb expected credit losses over the contractual life, including consideration of prepayments. Determining the adequacy of the allowance is complex and requires judgments that are inherently subjective, as it requires estimates that are susceptible to revision as additional information becomes available. While the Company has determined an allowance for credit losses it considers appropriate, there can be no assurance that the allowance will be sufficient to absorb future losses. The Company’s process for determining expected lifetime credit losses entails a loan-level, model-based approach and considers a broad range of information, including historical loss experience, current conditions, and reasonable and supportable forecasts. Credit loss is estimated for all loans. Accordingly, the Company has stratified the full loan population into segments sharing similar characteristics to perform the evaluation of the credit loss collectively. The Company can also further stratify loans of similar types, risk attributes, and methods for credit risk monitoring. The Company has determined pools based primarily on regulatory reporting codes as the loans within each pool share similar risk characteristics and there is sufficient historical peer loss data from the FFIEC to provide statistically meaningful support in the models developed. The Company further stratified the C&I portfolio into traditional C&I loans and SBA loans, as the loans in these pools have different repayment structures and credit risk characteristics. The Company also stratified C&I loans and consumer loans that do not require reserves, as the Company has third party agreements in place to cover credit losses. The Company has identified the following pools subject to an estimate of credit loss: (1) 1-4 Family Construction; (2) Other Construction; (3) Farmland; (4) Revolving Secured by 1-4 Family; (5) Residential Secured by First Liens; (6) Residential Secured by Junior Liens; (7) Multifamily; (8) CRE Owner Occupied; (9) CRE Non-Owner Occupied; (10) Agriculture; (11) C&I; (12) C&I SBA; (13) Consumer; and (14) Municipal. The Company has determined, given its limited loss experience, that peer data and other external data to support loss history provides the best basis for its assessment of expected credit losses. The Company believes that the use of peer loss data from 2008 to 2019 presents loss histories that appropriately reflect a full economic cycle, reflects asset-specific risk characteristics at each pool level identified, and includes a historical look-back period that is objective and reflective of future expected credit losses. Loss data from 2020 and beyond was excluded from the data set to exclude pandemic-related data in the models. The method for determining the estimate of lifetime credit losses includes, among other things, the following main components: (i) the use of Probability of Default and Loss Given Default assumptions under a Discounted Cash Flow model; (ii) a multi-scenario macroeconomic forecast; (iii) an initial and reasonable and supportable forecast period of one year for all loan segments; and (iv) a reversion period of one year using a linear transition method to historical loss rates. Given the inherent limitations of a quantitative-only model, qualitative adjustments are included to factor in data points not captured from a quantitative analysis alone. Qualitative criteria that can be considered includes, among other things, the following: • Concentrations – the existence and effect of any concentrations of credit, and changes in the level of such concentrations; • Volume – changes in the nature and volume of the portfolio and in the terms of the loans; • Economic – changes in international, national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments; • Policy – changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses; • Quality – changes in the volume and severity of past due loans, the volume of non-accrual loans, and the volume and severity of adversely classified or graded loans; and • External – the effect of other external factors, such as competition and legal and regulatory requirements on the level of estimated credit losses in the Company’s loan portfolio. Management reviews current information on a quarterly basis to assess the forecasted future economic impact for purposes of evaluating the adequacy of the ACL. The forecasted direction and magnitude of change with respect to future economic conditions is then assessed against the estimate in the model. Any changes resulting from the quarterly assessment are recorded in “Provision for credit losses” in the unaudited consolidated statements of income. The Audit Committee of the board of directors reviews the adequacy of the allowance at least quarterly. Accrued interest receivable is excluded from amortized cost of all financial instrument types and included in “Interest receivable and other assets” in the consolidated balance sheets. Accrued interest receivable is not subject to an estimate for credit loss, as the Company has a policy to charge off accrued interest deemed uncollectible in a timely manner. When a loan is placed on non-accrual status, which occurs within 90 days of a borrower becoming delinquent, interest previously accrued but not collected is reversed against current period income. If an individual loan’s characteristics have deteriorated to below a range of the overall pool, the loan would be individually assessed. Individually assessed loans are measured for credit loss based on one of the following methods: (i) present value of future expected cash flows, discounted at the loan’s effective interest rate; (ii) amount by which carrying value of the loan exceeds the loan’s observable market price; or (iii) the fair value of the collateral, less estimated selling costs, if the loan is collateral dependent. The Company applies the practical expedient and defines collateral dependent loans as those where the borrower is experiencing financial difficulty and on which payment is expected to be provided substantially through the operation or sale of the collateral. Troubled Debt Restructurings (“TDRs”) and Other Loan Modifications In accordance with the adoption of ASC 326, which includes ASU No. 2022-02, Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures , accounting guidance for TDRs for creditors has been eliminated. New guidance with respect to recognition, measurement, and disclosures of loans for borrowers experiencing financial difficulties supersedes guidance on TDRs. Under ASU No. 2022-02, the Company is required to evaluate whether a loan modification represents a new loan or a continuation of an existing loan. The amendment enhanced existing disclosure requirements and introduced new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty under criteria of principal forgiveness, interest rate reduction, other-than-insignificant payment delay, or term extension.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock Federal Home Loan Bank stock represents the Company’s investment in the stock of the FHLB and is carried at par value. While technically these are considered equity securities, there is no market for FHLB stock. Therefore, the shares are considered as other investment securities. Management periodically evaluates FHLB stock for impairment. Management’s determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as: (i) the significance of any decline in net assets of the FHLB, as compared to the capital stock amount for the FHLB and the length of time this situation has persisted; (ii) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB; (iii) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB; and (iv) the liquidity position of the FHLB. Both cash and stock dividends are reported as non-interest income.
Premises and Equipment	Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are provided for in amounts sufficient to relate the cost of depreciable assets to operations over their estimated service lives using a straight-line basis. The normal estimated lives used in determining depreciation are as follows: Equipment 3 - 12 years Furniture and fixtures 5 - 10 years Leasehold improvements 5 - 15 years Automobiles 3 - 5 years Leasehold improvements are amortized over the lesser of the useful life of the asset or the remaining term of the lease. The straight-line method of depreciation is followed for all assets for financial reporting purposes, but accelerated methods are used for tax purposes. When assets are sold or otherwise disposed of, the cost and related accumulated depreciation or amortization are removed from the accounts, and any resulting gain or loss is recognized in income for the period. The cost of maintenance and repairs is charged to expense as incurred.
Other Real Estate	Other Real Estate Real estate properties acquired through, or in lieu of, loan foreclosure, are classified as OREO, are to be sold, and are initially recorded at fair value of the property at the date of foreclosure less estimated selling costs. Any write-downs in value are recorded against the allowance for credit losses. Subsequent to foreclosure, valuations are periodically performed, and any revisions in the estimate of fair value are reported as adjustments to the carrying value of the real estate, provided the adjusted carrying amount does not exceed the original amount at foreclosure. Subsequent valuation adjustments are recognized as OREO write-downs. Revenues and expenses incurred from OREO property management are recorded in non-interest income and non-interest expense, respectively. During 2023 and 2022, the Bank did not foreclose on any loans.
BOLI	BOLI BOLI is recorded at the amount that can be realized under the insurance contract at the consolidated balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Increases in contract value are recorded as non-interest income, and insurance proceeds received are recorded as a reduction of the contract value.
Long-Term Assets	Long-Term Assets Premises, equipment, and other long-term assets are reviewed for impairment when events indicate that their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are adjusted to reflect their fair value.
Leases	Leases The Company records a ROUA in the consolidated balance sheets for those leases that convey rights to control use of identified assets for a period of time in exchange for consideration. The Company records a lease liability in the consolidated balance sheets for the present value of future payment commitments. All of the Company’s leases are comprised of operating leases in which the Company is the lessee of real estate property for branches and operations. The Company elected not to include short-term leases (i.e., leases with initial terms of 12 months or less) within the ROUA and lease liability. The Company adopted ASU 2016-02, Leases (Topic 842) as of January 1, 2022, which requires the Company to record an ROUA in the consolidated balance sheets for those leases that convey rights to control use of identified assets for a period of time in exchange for consideration. The Company is also required to record a lease liability in the consolidated balance sheets for the present value of future payment commitments. All of the Company’s leases are comprised of operating leases in which the Company is the lessee of real estate property for branches and operations. The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less) within the ROUA and lease liability. Known or determinable adjustments to the required minimum future lease payments were included in the calculation of the Company’s ROUA and lease liability. Adjustments to the required minimum future lease payments that are variable and will not be determinable until a future period, if any, are included as variable lease costs. Additionally, expected variable payments for common area maintenance, taxes, and insurance were unknown and not determinable at lease commencement and, therefore, were not included in the determination of the Company’s ROUA and lease liability. The value of the ROUA and lease liability is impacted by the amount of the periodic payment required, length of the lease term, and the discount rate used to calculate the present value of the minimum lease payments. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROUA and lease liability. ASC 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. For operating leases existing prior to January 1, 2022, the rate for the remaining lease term as of January 1, 2022 was used. The lease liability is reduced based on the discounted present value of remaining payments as of each reporting period. The ROUA value is measured using the lease liability as adjusted for prepaid or accrued lease payments and remaining lease incentives, unamortized direct costs, and impairment, if any.
Equity Investments	Equity Investments Equity investments with readily determinable fair values are carried at fair value, with changes in fair value reported in net income. Equity investments without readily determinable fair values are carried at cost, less impairment, if any, and adjusted for changes resulting from observable price changes in orderly transactions for the identical or similar investment.
Loss Contingencies	Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of an entire financial asset, a group of financial assets, or a participating interest in an entire financial asset are accounted for as sales when control has been relinquished. Control is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of more than trivial conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Included in the loan portfolio are loans guaranteed by the SBA, the Farm Service Agency, the Federal Agriculture Mortgage Corporation, and the United States Department of Agriculture, of which the guaranteed portion is expected to be sold in the secondary market in exchange for a one-time premium. At the time the guaranteed portion of the loan is sold, the unguaranteed portion and related right to service the entire loan is retained with the Company, to earn future servicing income. The loans held for sale are accounted for at the lower of cost or fair value, using the aggregate method. Government-guaranteed loans Servicing rights acquired through the origination of loans, which are subsequently sold with servicing rights retained, are recognized as separate assets or liabilities. Servicing assets and liabilities are initially recorded at fair value and are subsequently amortized in proportion to, and over the period of, the related net servicing income or expense. The amortized assets are assessed for impairment or increased obligations at the loan level, based on the fair value on a periodic basis.
Loan Commitments and Related Financial Instruments	Loan Commitments and Related Financial Instruments Financial instruments include off-balance sheet credit instruments, such as commitments to make loans, and financial standby letters of credit issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded. Loan commitments not unconditionally cancellable are subject to an estimate of credit loss under the CECL model. The Company’s process for determining the estimate of credit loss on loan commitments is the same as it is on loans. Reserves for unfunded commitments are included as a component of “Interest payable and other liabilities” in the consolidated balance sheets.
Stock-Based Compensation	Stock-Based Compensation Compensation cost is recognized for stock options and restricted stock awards (“RSAs”) issued to executives, directors, and employees, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the grant date fair value of stock options, while the fair value of the Company’s common stock at the date of grant is used for RSAs. Compensation cost is recognized over the required 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.
Supplemental Executive Retirement Plan	Supplemental Executive Retirement Plan The Bank has entered into a non-qualified retirement plan for the Chief Executive Officer based on a continuation of employment. The present value of annual post-retirement payments is allocated to expense over the years of required service.
Income Taxes	Income Taxes The Company files its income taxes on a consolidated basis with its subsidiary. The allocation of income tax expense represents each entity’s proportionate share of the consolidated provision for income taxes. Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. The Company accounts for uncertain tax positions in accordance with FASB ASC Topic No. 740, Accounting for Uncertainty in Income Taxes . A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that has a likelihood greater than 50% of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded.
Derivatives	Derivatives All derivative instruments are recorded at fair value. If derivative instruments are designated as hedges of fair values, both the change in the fair value of the hedge and the hedged item are included in current earnings. Fair value adjustments related to cash flow hedges, if any, are recorded in other comprehensive income or loss and reclassified to earnings when the hedged transaction is reflected in earnings.
Comprehensive Income or Loss	Comprehensive Income or Loss Comprehensive income or loss consists of net income and other comprehensive income or loss. Other comprehensive income or loss includes unrealized gains and losses on securities available-for-sale, net of tax, which are also recognized as separate components of shareholders’ equity.
EPS	EPS Basic EPS is net income divided by the weighted average number of common shares outstanding during the period less average unvested RSAs. Diluted EPS includes the dilutive effect of additional potential common shares related to unvested RSAs using the treasury stock method. During the years ended December 31, 2023 and 2022, there were no outstanding stock options. The Company has two forms of outstanding common stock: common stock and unvested RSAs. Holders of unvested RSAs receive non-forfeitable dividends at the same rate as common shareholders and they both share equally in undistributed earnings, and therefore the RSAs are considered participating securities. However, under the two-class method, the difference in EPS is not significant for these participating securities. (in thousands, except share and per share data) 2023 2022 Net income $ 47,734 $ 44,801 Weighted average basic common shares outstanding 17,166,592 17,128,282 Add: Dilutive effects of assumed vesting of restricted stock 21,377 37,328 Weighted average diluted common shares outstanding 17,187,969 17,165,610 Income per common share: Basic EPS $ 2.78 $ 2.61 Diluted EPS $ 2.78 $ 2.61 Anti-dilutive shares, which are excluded from the dilutive EPS calculation, were deemed to be immaterial.
Subordinated Notes	Subordinated Notes The subordinated notes are recorded at par with related debt issuance costs reported as a direct reduction from the carrying amount. Issuance costs are amortized over the remaining maturity of the notes and reflected in interest expense.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The consolidated financial statements include various estimated fair value information as of December 31, 2023 and 2022. Such information, which pertains to the Company’s financial instruments, does not purport to represent the aggregate net fair value of the Company. Further, the fair value estimates are based on various assumptions, methodologies, and subjective considerations, which vary widely among different financial institutions, and are subject to change.
Fair Value Measurements	Fair Value Measurements The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The Company bases the fair values on 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. Securities available-for-sale and derivatives, if any, are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record certain assets at fair value on a non-recurring basis, such as loans held for sale and certain collateral dependent impaired loans held for investment. These non-recurring fair value adjustments typically involve write-downs of individual assets due to application of lower of cost or fair value accounting. Accounting standards require the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: Level 1 : Quoted prices (unadjusted) for identical assets or liabilities in active markets that the Company has the ability to access as of the measurement date. Level 2 : Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 : Significant unobservable inputs that reflect the Company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The fair values of securities are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities, but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). As a result, if other assumptions had been used, the Company’s recorded earnings or disclosures could have been materially different from those reflected in these consolidated financial statements.
Subsequent Events	Subsequent Events
Recently Issued Accounting Standards, Accounting Standards Adopted, and Accounting Standards Issued But Not Yet Adopted	The following reflects recent accounting standards that have been adopted or are pending adoption by the Company. As discussed in Note 1, Basis of Presentation, the Company qualifies as an emerging growth company and as such, has elected to use the extended transition period for complying with new or revised accounting standards and is not subject to the new or revised accounting standards applicable to public companies during the extended transition period. The accounting standards discussed below indicate effective dates for the Company as an emerging growth company with the extended transition period. Accounting Standards Adopted On January 1, 2023, the Company adopted ASC 326, which replaces the current “incurred loss” model for recognizing credit losses with an “expected loss” model referred to as the CECL model. The CECL model applies to estimated credit losses on loans receivable, held-to-maturity debt securities, unfunded loan commitments, and certain other financial assets measured at amortized cost. Under ASC 326, available-for-sale debt securities are evaluated for impairment if fair value is less than amortized cost, with any estimated credit losses recorded through a credit loss expense and an allowance, rather than a write-down of the investment. Changes in fair value that are not credit-related will continue to be recorded in other comprehensive income. The Company adopted this standard using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance was effective for financial assets measured at amortized cost. For certain new disclosures required under ASC 326, such as credit quality indicators by year of origination, the Company has not restated comparative financial information before January 1, 2023 to conform under ASC 326. This adoption method is considered a change in accounting principle requiring additional disclosure of the nature and reason for the change, which is solely due to adoption of ASC 326. On January 1, 2023, the Company also adopted ASU No. 2022-02, Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, which had no material impact. Accounting Standards Issued But Not Yet Adopted In October 2023, the FASB issued ASU No. 2023-06, Disclosure Improvements (“ASU 2023-06”), amending disclosure or presentation requirements related to various subtopics in the FASB Accounting Standards Codification (the “Codification”). ASU 2023-06 was issued in response to the SEC’s initiative to update and simplify disclosure requirements. The SEC identified 27 disclosure requirements that were incremental to those in the Codification and referred them to the FASB for potential incorporation into U.S. GAAP. To avoid duplication, the SEC intended to eliminate those disclosure requirements from existing SEC regulations as the FASB incorporated them into the relevant Codification subtopics. ASU 2023-06 adds 14 of the 27 identified disclosure or presentation requirements to the Codification. ASU 2023-06 is to be applied prospectively, and early adoption is prohibited. For reporting entities subject to the SEC’s existing disclosure requirements, the effective dates of ASU 2023-06 will be the date on which the SEC’s removal of that related disclosure requirement from Regulation S-X or Regulation S-K becomes effective. If by June 30, 2027, the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the related amendment will be removed from the Codification and will not become effective for any entities. ASU 2023-06 is not expected to have a significant impact on the Company's consolidated financial statements. In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280) - Improvement to Reportable Segment Disclosures (“ASU 2023-07”), amending disclosure requirements related to segment reporting primarily through enhanced disclosure about significant segment expenses and by requiring disclosure of segment information on an annual and interim basis. ASU 2023-07 is effective January 1, 2024 and is not expected to have a significant impact on the Company's consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures (“ASU 2023-09”), which enhances the transparency and decision usefulness of income tax disclosures. ASU 2023-09 will require disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. Entities will also be required to disclose income/(loss) from continuing operations before income tax expense/(benefit) disaggregated between domestic and foreign, as well as income tax expense/(benefit) from continuing operations disaggregated by federal, state and foreign. ASU 2023-09 is effective January 1, 2025 and is not expected to have a significant impact on the Company's consolidated financial statements.
