Significant Accounting Policies [Text Block]	NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations ServisFirst Bancshares, Inc. (the “Company”) was formed on August 16, 2007 May 2005. 1, 11. Reclassification Certain amounts reported in prior years have been reclassified to conform to the current year’s presentation. These reclassifications had no Basis of Presentation and Accounting Estimates To prepare consolidated financial statements in conformity with U.S. generally accepted accounting principles, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and future results could differ. The allowance for credit losses, valuation of deferred tax assets and the fair value of financial instruments are particularly subject to change. All numbers are in thousands except share and per share data. Basis of Consolidation The consolidated financial statements include the accounts of the Company and other entities in which it has a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. Non-controlling interest consists of preferred shares in the Company's real estate investment trusts, SF Realty 1, third Cash, Due from Banks, Interest-Bearing Balances due from Financial Institutions Cash and due from banks include cash on hand, cash items in process of collection, amounts due from banks and interest bearing balances due from financial institutions. For purposes of cash flows, cash and cash equivalents include cash and due from banks and federal funds sold. Generally, federal funds are purchased and sold for one Debt Securities Debt securities are classified based on the Company’s intention on the date of purchase. All debt securities classified as available-for-sale are recorded at fair value with any unrealized gains and losses reported in accumulated other comprehensive income (loss), net of the deferred income tax effects. Debt securities that the Company has the positive intent and ability to hold to maturity are classified as held-to-maturity and are carried at historical cost and adjusted for amortization of premiums and accretion of discounts. Transfers of debt securities into the held-to-maturity category from available-for-sale category are made at fair value at the date of transfer. The unrealized holding gain or loss at the date of transfer is retained in other comprehensive income and in the carrying value of the held-to-maturity securities. Such amounts are amortized over the remaining life of the security. Interest and dividends on securities, including amortization of premiums and accretion of discounts calculated under the effective interest method, are included in interest income. For certain securities, amortization of premiums and accretion of discounts is computed based on the anticipated life of the security which may Restricted Equity Securities Investments in restricted equity securities without a readily determinable market value are carried at cost. Mortgage Loans Held for Sale The Company classifies certain residential mortgage loans as held for sale. Typically, mortgage loans held for sale are sold to a third not In the course of originating mortgage loans and selling those loans in the secondary market, the Company makes various representations and warranties to the purchaser of the mortgage loans. Each loan is underwritten using government agency guidelines. Any exceptions noted during this process are remedied prior to sale. These representations and warranties also apply to underwriting the real estate appraisal opinion of value for the collateral securing these loans. Under the representations and warranties, failure by the Company to comply with the underwriting and/or appraisal standards could result in the Company being required to repurchase the mortgage loan or to reimburse the investor for losses incurred (make whole requests) if such failure cannot be cured by the Company within the specified period following discovery. The Company continues to experience an insignificant level of investor repurchase demands. There were no December 31, 2022 2021. Loans Loans are reported at unpaid principal balances, less unearned fees and the allowance for credit losses. Interest on all loans is recognized as income based upon the applicable rate applied to the daily outstanding principal balance of the loans. Interest income on nonaccrual loans is recognized on a cash basis or cost recovery basis until the loan is returned to accrual status. A loan may six not one The accrual of interest on loans is discontinued when there is a significant deterioration in the financial condition of the borrower and full repayment of principal and interest is not 90 not Troubled debt restructurings (“TDRs”) are concessions granted to borrowers in the normal course of business, which would not may six Allowance for Credit Losses ( ACL ) and Impairment of Debt Securities As described below under Recently Adopted Accounting Pronouncements, 2016 - 13 , Financial Instruments-Credit Losses (Topic 326 326 January 1, 2020. ACL – Debt Securities Held to Maturity Management uses a systematic methodology to determine its ACL for held-to-maturity debt securities. The ACL is a contra-asset valuation account that is deducted from the amortized cost basis to present the net amount expected to be collected on the held-to-maturity portfolio. Management considers the effects of past events, current conditions, and reasonable and supportable forecasts on the collectability of the portfolio. The Company’s estimate of its ACL involves a high degree of judgment; therefore, Management’s process for determining expected credit losses may December 31, 2022 2021, no Impairment of Debt Securities Available for Sale For available-for-sale debt securities in an unrealized loss position, the Company will first not not Adjustments to the allowance are reported in the income statement as a component of credit loss expense. Debt securities are charged off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by the Company or when either of the aforementioned criteria regarding intent or requirement to sell is met specifically for available-for-sale debt securities. The Company excludes the accrued interest receivable balance from the amortized cost basis in measuring expected credit losses on debt securities and does not ACL – Loans The ACL is based on the Company’s evaluation of the loan portfolios, past loan loss experience, current asset quality trends, known and inherent risks in the portfolio, adverse situations that may may Loans with similar risk characteristics are evaluated in pools and, depending on the nature of each identified pool, the Company utilizes a discounted cash flow (“DCF”), probability of default / loss given default (“PD/LGD”) or remaining life method. The historical loss experience estimate by pool is then adjusted by forecast factors that are quantitatively related to the Company’s historical credit loss experience, such as national unemployment rates and gross domestic product. Losses are predicted over a period of time determined to be reasonable and supportable, and at the end of the reasonable and supportable period losses are reverted to long term historical averages. The reasonable and supportable period and reversion period are re-evaluated each quarter by the Company and are dependent on the current economic environment among other factors. The estimated credit losses for each loan pool are then adjusted for changes in qualitative factors not Credit losses for loans that no one The Company measures expected credit losses over the contractual term of a loan, adjusted for estimated prepayments. The contractual term excludes expected extensions, renewals and modifications unless there is a reasonable expectation that a troubled debt restructuring will be executed. Credit losses are estimated on the amortized cost basis of loans, which includes the principal balance outstanding, purchase discounts and premiums and deferred loan fees and costs. Accrued interest receivable on loans is excluded from the estimate of credit losses. ACL – Unfunded Loan Commitments The ACL is a liability account representing expected credit losses over the contractual period for which the Company is exposed to credit risk resulting from a contractual obligation to extend credit. No Foreclosed Real Estate Foreclosed real estate includes both formally foreclosed property and in-substance foreclosed property. At the time of foreclosure, foreclosed real estate is recorded at fair value less cost to sell, which becomes the property’s new basis. Any write downs based on the asset’s fair value at date of acquisition are charged to the allowance for credit losses. After foreclosure, these assets are carried at the lower of their new cost basis or fair value less cost to sell. Costs incurred in maintaining foreclosed real estate and subsequent adjustments to the carrying amount of the property are included in other operating expenses. Premises and Equipment Land is carried at cost. Premises and equipment are carried at cost less accumulated depreciation. Expenditures for additions and major improvements that significantly extend the useful lives of the assets are capitalized. Expenditures for repairs and maintenance are charged to expense as incurred. Assets which are disposed of are removed from the accounts and the resulting gains or losses are recorded in operations. Depreciation is calculated on a straight-line basis over the estimated useful lives of the related assets (3 to 39.5 years). Leasehold improvements are amortized on a straight-line basis over the lesser of the lease terms or the estimated useful lives of the improvements. Leases The Company leases certain office space and equipment under operating leases. Leases are recognized as a liability to make lease payments and as an asset representing the right to use the asset during the lease term, or “lease liability” and “right-of-use asset,” respectively. The lease liability is measured as the present value of remaining lease payments, discounted at the Company’s incremental borrowing rate. The Company reports its right-of-use assets in other assets and its lease liabilities in other liabilities within the Consolidated Balance Sheets. Certain of the leases include one not not None The Company does not 12 not Bank Owned Life Insurance ( BOLI ) BOLI is comprised of long-term life insurance contracts on the lives of certain current and past employees where the insurance policy benefit and ownership are retained by the employer. Its cash surrender value is an asset that the Company uses to partially offset the future cost of employee benefits. The cash surrender value accumulation on BOLI is permanently tax deferred if the policy is held to the insured person’s death and certain other conditions are met. Goodwill and Other Identifiable Intangible Assets The Company has recorded $13.6 million of goodwill at December 31, 2022 2015. not one Other identifiable intangible assets include a core deposit intangible recorded in connection with the acquisition of Metro Bancshares, Inc. The core deposit intangible was fully amortized as of January 2022. Derivatives and Hedging Activities As part of its overall interest rate risk management, the Company uses derivative instruments, which can include interest rate swaps, caps, and floors. All derivative instruments are carried at fair value on the Consolidated Balance Sheets. Accounting standards provide special accounting provisions for derivative instruments that qualify for hedge accounting. To be eligible, the Company must specifically identify a derivative as a hedging instrument and identify the risk being hedged. The derivative instrument must be shown to meet specific requirements under this accounting standard. The Company designates the derivative on the date the derivative contract is entered into as a hedge of the ( 1 2 The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as fair-value or cash-flow hedges to specific assets and liabilities on the Consolidated Balance Sheets or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, as necessary, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items. When it is determined that a derivative is not 1 no 2 3 4 no 5 no When hedge accounting is discontinued because it is determined that the derivative no no no The Company uses derivatives to hedge interest rate exposures associated with mortgage loan originations. Interest rate lock commitments related to loans that are originated for later sale are classified as derivatives. In the normal course of business, the Company regularly extends these rate lock commitments to customers during the loan origination process. The fair values of the Company’s rate lock commitments to customers as of December 31, 2022 2021 not not Revenue Recognition The Company recognizes revenue from contracts with customers in accordance with ASC Topic 606, Revenue from Contracts with Customers 606” ) While the majority of the Company’s revenue-generating transactions are excluded from the model for contracts with customers, including revenue generated from financial instruments, such as securities and loans, relevant revenue-generating transactions are classified within non-interest income and are described as follows: • Deposit account service charges – represent service fees for monthly activity and maintenance on customer accounts. Attributes can be transaction-based, item-based or time-based. Revenue is recognized when our performance obligation is completed which is generally monthly for maintenance services or when a transaction is processed. Payment for such performance obligations are generally received at the time the performance obligations are satisfied. • Credit card rewards program membership fees – represent memberships in our credit card rewards program and are paid annually by our cardholders at the time they open an account and on each anniversary. Revenue is recognized ratably over the membership period. Other non-interest income primarily includes income on bank owned life insurance contracts, letter of credit fees and gains on sale of loans held for sale. 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 uses the provisions of ASC 740 10, Income Taxes. 740 10 two first not second not 50% Stock-Based Compensation At December 31, 2022, Earnings per Common Share Basic earnings per common share are computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share include the dilutive effect of additional potential common shares issuable under stock options and performance shares. Loan Commitments and Related Financial Instruments Financial instruments, which include credit card arrangements, commitments to make loans and standby letters of credit, are 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. Instruments such as stand-by letters of credit are considered, and accounted for as, financial guarantees. The fair value of these financial guarantees is not Fair Value of Financial Instruments Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 21. Comprehensive Income Comprehensive income consists of net income and other comprehensive income. Accumulated comprehensive (loss) income, which is recognized as a separate component of equity, includes unrealized gains and losses on available-for-sale debt securities and amortization of unrealized gains and losses on debt securities transferred from available-for-sale to held-to-maturity at the time of transfer.

Disclosure of Variable Interest Entities [Text Block]	NOTE 7. VARIABLE INTEREST ENTITIES (VIEs) The Company utilizes special purpose entities (SPEs) that constitute investments in limited partnerships that undertake certain development projects to achieve federal and state tax credits. These SPEs are typically structured as VIEs and are thus subject to consolidation by the reporting enterprise that absorbs the majority of the economic risks and rewards of the VIE. To determine whether it must consolidate a VIE, the Company analyzes the design of the VIE to identify the sources of variability within the VIE, including an assessment of the nature of risks created by the assets and other contractual obligations of the VIE, and determines whether it will absorb a majority of that variability and has the power to direct the activities that most significantly impact the economic performance of the entity. The Company has invested in limited partnerships as a funding investor. The partnerships are single purpose entities that lend money to real estate investors for the purpose of acquiring and operating, or rehabbing, commercial property.

The compensation cost that has been charged against income for the plan was approximately $3.2 million, $1.9 million and $1.3 million for the years ended December 31, 2022, 2021 2020, Stock Incentive Plan On March 23, 2009, 2009 2009 2009 2014, As of December 31, 2022, Stock-based compensation expense for stock-based awards is based on the grant-date fair value. For stock option awards, the fair value is estimated at the date of grant using the Black-Scholes-Merton valuation model. This model requires the input of highly subjective assumptions, changes to which can materially affect the fair value estimate. The fair value of each option granted is estimated on the date of grant using the Black-Scholes-Merton model based on the weighted-average assumptions for expected dividend yield, expected stock price volatility, risk-free interest rate and expected life of options granted. There were no grants of stock options during the years ended December 31, 2022 2021.

ACL – Debt Securities Held to Maturity Management uses a systematic methodology to determine its ACL for held-to-maturity debt securities. The ACL is a contra-asset valuation account that is deducted from the amortized cost basis to present the net amount expected to be collected on the held-to-maturity portfolio. Management considers the effects of past events, current conditions, and reasonable and supportable forecasts on the collectability of the portfolio. The Company’s estimate of its ACL involves a high degree of judgment; therefore, Management’s process for determining expected credit losses may December 31, 2022 2021, no Impairment of Debt Securities Available for Sale For available-for-sale debt securities in an unrealized loss position, the Company will first not not Adjustments to the allowance are reported in the income statement as a component of credit loss expense.

The historical loss experience estimate by pool is then adjusted by forecast factors that are quantitatively related to the Company’s historical credit loss experience, such as national unemployment rates and gross domestic product. Losses are predicted over a period of time determined to be reasonable and supportable, and at the end of the reasonable and supportable period losses are reverted to long term historical averages.
