Accounting Policies [Abstract]
Nature of Operations and Summary of Significant Accounting Policies	Nature of Operations and Summary of Significant Accounting Policies Nature of Operations Third Coast Bancshares, Inc. (“Bancshares”), through its subsidiary, Third Coast Bank, a Texas banking association (the “Bank”), and the Bank’s subsidiary, Third Coast Commercial Capital, Inc. (“TCCC”), (collectively known as the “Company,” “we,” “us” or “our”), provide general consumer and commercial banking service s through 17 branch offices locate d in the Greater Houston, Dallas-Fort Worth, and Austin-San Antonio markets. Branch locations include: Humble, Kingwood, Beaumont, Port Arthur, Houston-Galleria, Conroe, Pearland, Lake Jackson, Dallas, Fort Worth, Plano, Detroit, La Vernia, Nixon, Austin, Georgetown and San Antonio. The Bank is engaged in traditional community banking activities, which include commercial and retail lending, deposit gathering, and investment and liquidity management activities. The Bank’s primary deposit products are demand deposits, money market accounts and certificates of deposit; its primary lending products are commercial business and real estate, residential construction, real estate mortgage and consumer loans. TCCC engages in accounts receivable factoring activities. The Company is subject to the regulations of certain government agencies and undergoes periodic examinations by those regulatory authorities. Basis of Presentation The unaudited consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information, reporting practices prescribed by the banking industry, and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements and should be read in conjunction with the Company's annual consolidated financial statements for the years ended December 31, 2023 and 2022 included in the Company's Annual Report on Form 10-K filed with the SEC on March 7, 2024. The December 31, 2023 consolidated balance sheet has been derived from the audited financial statements for the year ended December 31, 2023. In the opinion of management, all adjustments that were recurring in nature and considered necessary have been included for fair presentation of the Company’s financial position and results of operations. Operating results for the three months ended March 31, 2024 are not necessarily indicative of results that may be expected for the full year ending December 31, 2024. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates. Material estimates that are included in the financial statements include the allowance for credit losses, the valuation of goodwill and other intangible assets and the fair value of financial instruments. The accompanying unaudited consolidated financial statements include the accounts of Bancshares, the Bank, and TCCC. All significant intercompany transactions and balances have been eliminated in consolidation. The Company has evaluated subsequent events for potential recognition and/or disclosure through the date the consolidated financial statements were issued. Cash and Cash Equivalents Cash and cash equivalents include cash, deposits with other financial institutions that have initial maturities of less than 90 days when acquired by the Company and federal funds sold. Investment Securities Available-For-Sale Investment securities available-for-sale consist of bonds, notes, and debentures that are not classified as trading securities or held-to-maturity securities. Investment securities available-for-sale are held for indefinite periods of time and carried at fair value, with the unrealized holding gains and losses reported as a component of other comprehensive income, net of tax. Management determines the appropriate classification of investment securities at the time of purchase. Loans Loans are stated at the amount of unpaid principal, reduced by unearned income and an allowance for credit losses (“ACL”). Interest on loans is recognized using the effective interest method and includes amortization of deferred loan origination fees and costs over the life of the loans. The accrual of interest on loans is discontinued when there is a clear indication that the borrower’s cash flow may not be sufficient to meet payments as they become due, which is generally when a loan is 90 days past due. When a loan is placed on non-accrual status, all previously accrued and unpaid interest is reversed. Interest income is subsequently recognized on a cash basis as long as the remaining book balance of the asset is deemed to be collectible. If collectability is questionable, then cash payments are applied to principal. A loan is placed back on accrual status when both principal and interest are current and it is probable that the Company will be able to collect all amounts due (both principal and interest) according to the terms of the loan agreement. From time to time, the Company modifies its loan agreement with a borrower. The loan refinancing and restructuring guidance is considered for each loan modified to determine whether a modification results in a new loan or a continuation of an existing loan. In some cases, the loan may be considered restructured if the borrower is experiencing financial difficulties and the loan has been modified. Loan modifications to borrowers experiencing financial difficulty may be in the form of principal forgiveness, an interest rate reduction, an other-than-insignificant payment delay, or a term extension or a combination thereof, among other things. The Company has certain lending policies and procedures in place that are designed to maximize loan income with an acceptable level of risk. Management reviews and approves these policies and procedures on a regular basis and makes changes as appropriate. Management receives frequent reports related to loan originations, quality, concentrations, delinquencies, non-performing, and potential problem loans. Diversification in the loan portfolio is a means of managing risk associated with fluctuations in economic conditions, both by type of loan and geography. Commercial loans are underwritten after evaluating and understanding the borrower’s ability to operate profitably and effectively. Underwriting standards are designed to determine whether the borrower possesses sound business ethics and practices and to evaluate current and projected cash flows to determine the ability of the borrower to repay their 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. Most commercial loans are secured by the assets being financed or other business assets, such as accounts receivable or inventory, and include personal guarantees. Real estate loans are also subject to underwriting standards and processes similar to commercial and agricultural loans. These loans are underwritten primarily based on projected cash flows and, secondarily, as loans secured by real estate. The repayment of real estate loans is generally largely dependent on the successful operation of the property securing the loans or the business conducted on the property securing the loan. Real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. The properties securing the Company’s real estate portfolio are generally diverse in terms of type and geographic location primarily throughout the Greater Houston, Dallas, and Austin-San Antonio metropolitan areas. This diversity helps reduce the exposure to adverse economic events that affect any single market or industry. Generally, real estate loans are owner occupied which further reduces the Company’s risk. Agricultural loans are subject to underwriting standards and processes similar to commercial loans. Agricultural loans are primarily made based on the identified cash flows of the borrower and, secondarily, on the underlying collateral provided by the borrower. Most agricultural loans are secured by the agriculture related assets being financed, such as farmland, cattle, or equipment, and include personal guarantees. The Company utilizes methodical credit standards and analysis to supplement its policies and procedures in underwriting consumer loans. The Company’s loan policy addresses types of consumer loans that may be originated and the collateral, if secured, which must be perfected. The relatively smaller individual dollar amounts of consumer loans that are spread over numerous individual borrowers also minimizes the Company’s risk. Allowance for Credit Losses As further discussed below, we adopted Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” on January 1, 2023. Accounting Standards Codification (“ASC”) Topic 326 (“ASC 326”) replaced the previous “incurred loss” model for measuring credit losses, which encompassed allowances for current known and inherent losses within the portfolio, with an “expected loss” model, which encompasses allowances for losses expected to be incurred over the life of the portfolio. The new current expected credit loss (“CECL”) model requires the measurement of all expected credit losses for financial assets measured at amortized cost and certain off-balance sheet credit exposures based on historical experience, current conditions, and reasonable and supportable forecasts. In connection with the adoption of ASC 326, we revised certain accounting policies and implemented certain accounting policy elections. The revised accounting policies are described below. Allowance For Credit Losses - Available-for-Sale Securities : For available-for-sale securities in an unrealized loss position, we first assess whether (i) we intend to sell or (ii) it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If either case is affirmative, any previously recognized allowances are charged-off and the security's amortized cost is written down to fair value through income. If neither case is affirmative, the security is evaluated to determine whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and any adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are 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, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Adjustments to the allowance are reported in our income statement as a component of provision for credit loss expense. Management has made the accounting policy election to exclude accrued interest receivable on available-for-sale securities from the estimate of credit losses. Available-for-sale securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by management or when either of the aforementioned criteria regarding intent or requirement to sell is met. Further information regarding our policies and methodology used to estimate the allowance for credit losses on available-for-sale securities is presented in Note 2 - Investment Securities Available-for-Sale. Prior to the adoption of ASU 2016-13, declines in the fair value of available-for-sale securities below their cost that were deemed to be other than temporary were reflected in earnings as realized losses. In estimating other-than-temporary impairment losses prior to January 1, 2023, management considered, among other things, (i) the length of time and the extent to which the fair value had been less than cost, (ii) the financial condition and near-term prospects of the issuer and (iii) the intent and our ability to retain our investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. Allowance for Credit Losses - Loans : The allowance for credit losses on loans is a contra-asset valuation account, calculated in accordance with ASC 326, that is deducted from the amortized cost basis of loans to present management's best estimate of the net amount expected to be collected. Loans are charged-off against the allowance when deemed uncollectible by management. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Adjustments to the allowance are reported in our income statement as a component of provision for credit loss expense. Management has made the accounting policy election to exclude accrued interest receivable on loans from the estimate of credit losses. Further information regarding our policies and methodology used to estimate the allowance for credit losses on loans is presented in Note 3 - Loans and Allowance for Credit Losses. Allowance For Credit Losses - Off-Balance Sheet Credit Exposures : The allowance for credit losses on off-balance sheet credit exposures is a liability account, calculated in accordance with ASC 326, representing expected credit losses over the contractual period for which we are exposed to credit risk resulting from a contractual obligation to extend credit. No allowance is recognized if we have the unconditional right to cancel the obligation. The allowance is reported as a component of other liabilities in our consolidated balance sheets. Adjustments to the allowance are reported in our income statement as a component of provision for credit loss expense. Further information regarding our policies and methodology used to estimate the allowance for credit losses on off-balance sheet credit exposures is presented in Note 10 - Financial Instruments with Off-Balance Sheet Risk. Servicing Assets Certain Small Business Administration (“SBA”) loans are originated and intended for sale in the secondary market. They are carried at the lower of cost or estimated fair value in the aggregate. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. Gains or losses recognized upon the sale of loans are determined on a specific identification basis and are included in non-interest income. SBA loan transfers are accounted for as sales when control over the loan has been surrendered. Control over such loans is deemed to be surrendered when (i) the assets have been isolated from the Company, (ii) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (iii) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. The Company applies guidance issued by the Financial Accounting Standards Board (the “FASB”) that clarifies the accounting and reporting standards for transfers and servicing of financial assets and extinguishments of liabilities, in which, after a transfer of financial assets, an entity recognizes the financial and servicing assets it controls and liabilities it has incurred, derecognizes financial assets when control has been surrendered, and derecognizes liabilities when extinguished. To calculate the gain or loss on sale of loans, the Company’s investment in the loan is allocated among the retained portion of the loan, the servicing retained, the interest-only strip and the sold portion of the loan, based on the relative fair value of each portion. The gain or loss on the sold portion of the loan is recognized based on the difference between the sale proceeds and the allocated investment. As a result of the relative fair value allocation, the carrying value of the retained portion is discounted, with the discount accreted to interest income over the life of the loan. Servicing assets are amortized over an estimated life using a method that is in proportion to the estimated future servicing income. In the event future prepayments exceed management’s estimates and future cash flows are inadequate to cover the servicing asset, additional amortization would be recognized. The portion of servicing fees in excess of the contracted servicing fees is reflected as interest-only strips receivable, which are classified as available for sale and are carried at fair value. At March 31, 2024 and December 31, 2023, the Company was servicing loans previously sold of approximately $ 5.2 million and $ 4.8 million, respectively. The related servicing assets receivable were not material to the consolidated financial statements at March 31, 2024 and December 31, 2023 . Premises and Equipment Buildings, leasehold improvements, furniture and fixtures, and equipment are carried at cost, less accumulated depreciation, computed principally by the straight-line method based on the estimated useful lives of the related asset. Land is not depreciated. Major replacements and betterments are capitalized while maintenance and repairs are charged to expense when incurred. Gains or losses on dispositions are reflected in income as incurred. A small portion of the building’s floor space is currently leased out to tenants and recognized in income when earned. Operating Leases The Company leases certain office space, stand-alone buildings, and equipment which are recognized as operating lease right-of-use assets and operating lease liabilities in the consolidated balance sheets. Lease liabilities represent the Company's liability to make lease payments under these leases on a discounted basis and are amortized on a straight-line basis over the lease term for each related lease agreement. Right-of-use assets represent the Company's right to use, or control the use of, leased assets for their lease term and are amortized over the lease term of the related lease agreement. The Company does not recognize short-term operating leases on the consolidated balance sheets. A short-term lease has a term of 12 months or less and does not have a purchase option that is likely to be exercised. Other Real Estate Owned Other real estate owned represents properties acquired through or in lieu of loan foreclosure and are initially recorded at fair value less estimated costs to sell. Any write-down to fair value at the time of transfer to other real estate owned is charged to the allowance for credit losses. Costs of improvements are capitalized, whereas costs relating to holding other real estate owned and subsequent adjustments to the value are expensed. Operating and holding expenses of such properties, net of related income, are included in loan operations and other real estate owned expense on the accompanying consolidated statements of income. Gains or losses on dispositions are reflected in income as incurred. At March 31, 2024 and December 31, 2023, the Company had no other real estate owned. Bank-Owned Life Insurance The Company has purchased life insurance policies on certain employees. These bank-owned life insurance (“BOLI”) policies are recorded in the accompanying consolidated balance sheets at their cash surrender values. Income from these policies and changes in the cash surrender values are reported in the accompanying consolidated statements of income. Non-Marketable Securities The Company has restricted non-marketable securities which represent investment in Federal Home Loan Bank (“FHLB”) stock, Federal Reserve Bank (“FRB”) stock and Texas Independent Bank (“TIB”) stock. These investments are not readily marketable and are carried at cost, which approximates fair value. As a member of the FHLB, FRB and TIB systems, the Company is required to maintain minimum level of investments in stock, based on the level of borrowings and other factors. Both cash and stock dividends are reported as income. Goodwill and Core Deposit Intangibles Goodwill represents the excess of cost over fair value of net assets acquired in a business combination. Goodwill is not amortized and is evaluated for impairment at least annually and on an interim basis if an event triggering impairment may have occurred. Core deposit intangibles are acquired customer relationships arising from bank acquisitions and are amortized on a straight-line basis over their estimated useful life of ten years. Core deposit intangibles are tested for impairment whenever events or changes in circumstances indicate the carrying amount of assets may not be recoverable from future undiscounted cash flows. Derivative Financial Instruments Derivatives are recorded on our consolidated balance sheets as assets and liabilities measured at their fair value. The accounting for increases and decreases in the value of derivatives depends upon the use of the derivatives and whether the derivatives qualify for hedge accounting. At inception of the derivative, we designate the derivative as one of two types based on our intention and belief as to the likely effectiveness as a hedge. These two types are (1) a hedge of the fair value of a recognized asset or liability (“Fair Value Hedge”), and (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“Cash Flow Hedge”). For certain Fair Value Hedges, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item, are recognized in noninterest income or expense in our consolidated statements of income. Fair Value Hedge instruments offered by the Company which are included in noninterest income or expense include pass-through interest rate swap products to qualified commercial banking customers. Under this type of contract, the Company enters into an interest rate swap contract with a customer, while at the same time entering into an offsetting interest rate swap contract with a financial institution counterparty. Changes in the fair value of the underlying derivatives are designed to offset each other so they would not significantly impact the Company's operating results. The Company also enters into Risk Participation Agreements (“RPAs”) with other banks, primarily to share a portion of the risk of borrower default related to the interest rate swap on certain participated loans. Gains or losses on these types of derivatives are also included in noninterest income in our consolidated statements of income. A one-way interest rate swap is another type of Fair Value Hedge instrument offered to our customers. Under this type of arrangement, the Company extends a conventional fixed-rate loan to the borrower and then subsequently hedges the interest rate risk of that loan by entering into a swap for its own balance sheet to convert the fixed-rate loan to a synthetic floating rate asset. These types of swaps lock in the Company's spread over its cost of funds for the life of the loan. The gain or loss on this type of derivative is included in interest income in our consolidated statements of income. For a Cash Flow Hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. Cash Flow Hedge instruments include pay-fixed interest rate swap agreements with a financial institution counterparty. Net cash settlements on cash flow hedges are recorded in interest expense in the consolidated statements of income. Net cash settlements on one-way swap derivatives are recorded in interest income in the consolidated statements of income. Net cash settlements on pass-through interest rate swaps and RPAs are reported in noninterest income in the consolidated statements of income. Cash flows on hedges are classified in the cash flow statement the same as the items being hedged. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains and/or losses accumulated in other comprehensive income are amortized into earnings over the same period which the hedged transaction will affect earnings. We formally document the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions, at the inception of the hedging relationship. This documentation includes linking Cash Flow Hedges to specific assets and liabilities on the consolidated balance sheets or to forecasted transactions. Business Combinations The Company applies the acquisition method of accounting for business combinations. Under the acquisition method, the acquiring entity in a business combination recognizes 100% of the assets acquired and liabilities assumed at their acquisition date fair values. Management utilizes valuation techniques appropriate for the asset or liability being measured in determining these fair values. Any excess of the purchase price over amounts allocated to assets acquired, including identifiable intangible assets, and liabilities assumed is recorded as goodwill. Adjustments identified during the measurement period are recognized in the reporting period in which the adjustment amounts are determined. Acquisition related costs are expensed as incurred. Comprehensive Income Comprehensive income includes all changes in shareholders’ equity during a period, except those resulting from transactions with shareholders. Other than net income, comprehensive income includes the net effect of changes in the fair value of securities available-for-sale and certain derivative instruments designated as cash flow hedges. Revenues from Contracts with Customers The Company’s revenues from services such as deposit related fees, wire transfer fees, interchange fees on debit cards, ATM fees, and merchant fee income are presented within the service charges and fees category in the accompanying consolidated statements of income and are recognized as revenue as the Company satisfies its obligation to the customer. Advertising and Marketing Expenses Advertising and marketing expenses consist of the Company’s advertising in its local market area and are expensed as incurred. Advertising and marketing expenses we re $ 355,000 and $ 686,000 for the three months ended March 31, 2024 and 2023, respectively. The expenses are included within noninterest expense in the accompanying consolidated statements of income. Income Taxes The Company files a consolidated income tax return with its subsidiary. Federal income tax expense or benefit is allocated on a separate return basis. Deferred tax assets and liabilities are reflected at currently enacted income tax rates applicable to the period in which the deferred tax assets and liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Share-Based Compensation Compensation expense for stock options is based on the fair value of the award on the measurement date, which, for the Company, is the date of the grant and is recognized ratably over the service period of the award. The fair value of stock options is estimated using the Black-Scholes option-pricing model. Basic and Diluted Earnings Per Common Share Earnings per common share is computed in accordance with ASC Topic 260, “Earnings Per Share.” Basic earnings per common share is computed by dividing net earnings allocated to common stock by the weighted-average number of common shares outstanding during the applicable period. Diluted earnings per common share is computed by using the net earnings allocated to common stock plus dividends on dilutive convertible preferred stock, divided by the sum of 1) the weighted-average number of shares determined for the basic earnings per common share computation, 2) the dilutive effect of stock compensation using the treasury stock method, and 3) the dilutive effect of convertible preferred stock using the if-converted method. A reconciliation of the weighted-average shares used in calculating basic earnings per common share and the weighted average common shares used in calculating diluted earnings per common share for the reported periods is provided in Note 16 – Earnings Per Common Share. Reclassification Certain amounts in prior period consolidated financial statements may have been reclassified to conform to current period presentation. These reclassifications are immaterial and have no effect on net income, total assets or shareholders’ equity. Recently Adopted Accounting Standards: ASU 2016-13 - Current Expected Credit Losses In June 2016, the FASB issued ASU 2016-13, “Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 is effective for fiscal years beginning after December 15, 2022. ASU 2016-13 is intended to replace the incurred loss model for loans and other financial assets with an expected loss model, which is known as the current expected credit loss, or CECL, model. The change is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures such as loan commitments, standby letters of credit, financial guarantees, and other similar instruments. ASC 326 also made changes to the accounting for available-for-sale debt securities, specifically requiring credit losses for available-for-sale debt securities to be presented as an allowance rather than a write-down on available-for-sale debt securities. The Company adopted ASC 326 using the modified retrospective method for financial instruments measured at amortized cost and off-balance sheet credit exposure which requires reporting periods beginning after January 1, 2023 to be presented under ASC 326 guidance while prior period amounts to continue to be reported in accordance with previously applicable inherent risk methodology. Effective January 1, 2023, the Company adopted the standard and recorded an increase in the allowance for credit losses of $ 4.0 million and a net after-tax adjustment to retained earnings of $ 3.2 million for the cumulative effect of adopting ASC 326 for its loan portfolio. The following table illustrates the impact of ASC 326 on the allowance for credit losses by loan category at the January 1, 2023 adoption date: January 1, 2023 (Dollars in thousands) Post-ASC 326 Adoption Pre-ASC 326 Adoption Impact of ASC 326 Adoption Real estate loans: Non-farm non-residential owner occupied $ 5,097 $ 3,773 $ 1,324 Non-farm non-residential non-owner occupied 8,351 5,741 2,610 Residential 2,060 1,064 996 Construction, development & other 4,661 3,053 1,608 Farmland 94 82 12 Commercial & industrial 13,366 16,269 ( 2,903 ) Consumer 10 6 4 Municipal and other 712 363 349 $ 34,351 $ 30,351 $ 4,000 Recently Adopted Accounting Standards: ASU 2022-02 - Troubled Debt Restructurings and Vintage Disclosures The Company adopted ASU 2022-02, “Financial Instruments-Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures” on January 1, 2023 .

Investments, Debt and Equity Securities [Abstract]
Investment Securities Available for Sale	2. Investment Securities Available-for-Sale Investment securities have been classified in the consolidated balance sheets according to management’s intent. Management assesses securities in its investment portfolio for impairment on a quarterly basis or when events or circumstances suggest that the carrying amount of an investment may be impaired. In accordance with ASC 326, available-for-sale securities are evaluated as of each reporting date when the fair value is less than amortized cost, and credit losses are to be calculated individually using a discounted cash flow method through which management compares the present value of the expected cash flows with the amortized costs. An allowance for credit losses is established to reflect the credit loss component of the decline in fair value. Factors management considers in assessing whether a discounted cash flow method evaluation is needed for a security whose fair value is less than amortized costs include: (1) management will assess whether it intends to sell, or if it is more likely than not it will be required to sell, the security before recovery of the amortized cost basis; (2) the length of time (duration) and the extent (severity) to which the market value has been less than costs; (3) the financial condition and near-term prospects of the issuer, including any specific events which may influence the operations of the issuer, such as changes in technology that impair the earnings potential of the investment or the discontinuance of a segment of the business that may affect the future earnings potential; and (4) changes in the rating of the security by a rating agency. The carrying amount of securities and their approximate fair values as of March 31, 2024 and December 31, 2023 are as follows: March 31, 2024 (Dollars in thousands) Amortized Gross Gross Estimated Securities available-for-sale: U.S government and agency securities $ 19,234 $ 34 $ 92 $ 19,176 State and municipal securities 1,000 6 — 1,006 Mortgage-backed securities and collateralized mortgage obligations 125,637 1,327 917 126,047 Corporate bonds 105,663 647 6,248 100,062 $ 251,534 $ 2,014 $ 7,257 $ 246,291 December 31, 2023 (Dollars in thousands) Amortized Gross Gross Estimated Securities Available-for-sale: U.S. government and agency securities $ 4,017 $ — $ 26 $ 3,991 Mortgage-backed securities and collateralized mortgage obligations 77,703 1,599 769 78,533 Corporate bonds 100,371 861 5,669 95,563 $ 182,091 $ 2,460 $ 6,464 $ 178,087 Mortgage-backed securities are typically issued with stated principal amounts and are backed by pools of mortgages that have loans with varying maturities. The characteristics of the underlying pool of mortgages, such as prepayment risk, are passed on to the certificate holder. Accordingly, the term of mortgage-backed securities approximates the term of the underlying mortgages and can vary significantly due to prepayments. Therefore, schedules of maturities for mortgage-backed securities have been excluded from the below disclosure. The amortized cost and estimated fair value of securities available-for-sale at March 31, 2024, by contractual maturity, are shown below. March 31, 2024 Securities Available-for-Sale (Dollars in thousands) Amortized Estimated Due in one year or less $ 2,946 $ 2,962 Due from one year to five years 10,368 10,483 Due from five to ten years 93,349 87,623 Over ten years 19,234 19,176 125,897 120,244 Mortgage-backed securities and collateralized mortgage obligations 125,637 126,047 $ 251,534 $ 246,291 The following table summarizes securities with unrealized losses at March 31, 2024 and December 31, 2023, aggregated by major security type and length of time in a continuous unrealized loss position: March 31, 2024 (Dollars in thousands) Less Than 12 Greater Than 12 Total Estimated Securities available-for-sale: U.S. government and agency securities $ 92 $ — $ 92 $ 8,903 Mortgage-backed securities and collateralized mortgage obligations — 917 917 15,322 Corporate bonds 546 5,702 6,248 72,682 $ 638 $ 6,619 $ 7,257 $ 96,907 December 31, 2023 (Dollars in thousands) Less Than 12 Greater Than 12 Total Estimated Securities available-for-sale: U.S. government and agency securities $ 26 $ — $ 26 $ 3,991 Mortgage-backed securities and collateralized mortgage obligations — 769 769 16,001 Corporate bonds 128 5,541 5,669 64,143 $ 154 $ 6,310 $ 6,464 $ 84,135 There were 39 investments in an unrealized loss position at March 31, 2024, and 37 investments in an unrealized loss position at December 31, 2023. As of March 31, 2024, no allowance for credit losses has been recognized on available-for-sale securities in an unrealized loss position as management does not believe any of the securities are impaired due to reasons of credit quality. This is based upon our analysis of the underlying risk characteristics, including credit ratings, and other qualitative factors related to our available-for-sale securities and in consideration of our historical credit loss experience and internal forecasts. The issuers of these securities continue to make timely principal and interest payments under the contractual terms of the securities. In addition, a portion of our investments are guaranteed by the U.S. Government, Treasury, or municipalities. Furthermore, management does not have the intent to sell any of the securities classified as available-for-sale in the table above and believes that it is more likely than not that we will not have to sell any such securities before a recovery of cost. The unrealized losses are due to increases in market interest rates over the yields available at the time the underlying securities were purchased. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline. There were no securities pledged as collateral as of March 31, 2024 a nd December 31, 2023. Proceeds from the sales of securities and their gross gains for the three months ended March 31, 2024 we re $ 5.3 million and $ 157,000, respectively. For the three months ended March 31, 2023, p roceeds from the sales of securities and their gross gains we re $ 3.9 million and $ 97,000 , respectively. No losses were recorded on the sales of securities for the three months ended March 31, 2024 and 2023.

Non-accrual and Past Due Loans Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. As mentioned in Note 1, the accrual of interest on loans is discontinued when there is a clear indication that the borrower’s cash flow may not be sufficient to meet payments as they become due, which is generally when a loan is 90 days past due. Non-accrual loans and accruing loans past due more than 90 days segregated by class of loans were as follows: March 31, 2024 December 31, 2023 (Dollars in thousands) Non-accrual Accruing loans Non-accrual Accruing loans Real estate loans: Non-farm non-residential owner occupied $ 2,369 $ 2,894 $ 1,211 $ — Non-farm non-residential non-owner occupied 1,225 — 1,235 — Residential 2,837 293 2,938 — Construction, development & other 406 427 247 — Commercial & industrial 11,293 — 11,018 670 $ 18,130 $ 3,614 $ 16,649 $ 670 Of the non-accrual loans disclosed above, $ 4.9 million and $ 8.8 million did not have an allowance for credit loss at March 31, 2024 and December 31, 2023, respectively. As of March 31, 2024 and 2023, the amount of income that would have been accrued for loans on non-accrual was approximately $ 324,000 and $ 339,000 , respectively.

This guidance eliminated TDR accounting for loans in which the borrower was experiencing financial difficulty and the creditor was granted a concession. A loan is now considered modified under ASU 2022-02 if the borrower is experiencing financial difficulties and the loan has been modified. Modifications may include interest rate reductions or below market interest rates, restructuring amortization schedules and other actions intended to minimize potential losses. For the three months ended March 31, 2024, no loans were modified for borrowers experiencing financial difficulty. The table below presents the amortized cost basis of loans at period end that were both experiencing financial difficulty and modified during the year ended December 31, 2023, by class and type of modification. December 31, 2023 Loan modifications (Dollars in thousands) Number Post- Principal Forgiveness Adjusted Payment Combined Commercial & industrial 3 $ 6,970 $ — $ — $ 63 $ 63 On an ongoing basis, the performance of modified loans for borrowers experiencing financial difficulty is monitored for subsequent payment default. Payment default is recognized when the borrower is 90 days or more past due. As of March 31, 2024 and December 31, 2023, there were no modified loans in the previous twelve-month period that were in default. Credit Quality Indicators Credit Quality Indicators. From a credit risk standpoint, the Company classifies its loans in one of six categories: (i) pass, (ii) special mention, (iii) substandard, (iv) purchased credit impaired, (v) doubtful, or (vi) loss. The classifications of loans reflect a judgment about the risks of default and loss associated with the loan. The Company reviews the ratings on credits monthly. Ratings are adjusted to reflect the degree of risk and loss that is felt to be inherent in each credit as of each monthly reporting period. The Company’s methodology is structured so that specific allocations are increased in accordance with deterioration in credit quality (and a corresponding increase in risk and loss) or decreased in accordance with improvement in credit quality (and a corresponding decrease in risk and loss). (i) The Company has several pass credit grades that are assigned to loans based on varying levels of credits, ranging from credits that are secured by cash or marketable securities, to watch credits that have all the characteristics of an acceptable credit risk but warrant more than the normal level of supervision. (ii) Special mention loans are loans that still show sufficient cash flow to service their debt but show a declining financial trend with potential cash flow shortages if trends continue. This category should be treated as a temporary grade. If cash flow deteriorates further to become negative, then a substandard grade should be given. If cash flow trends begin to improve then an upgrade back to pass would be justified. Nonfinancial reasons for rating a credit special mention include management problems, pending litigation, an ineffective loan agreement or other material structure weakness. (iii) A substandard loan has material weakness in the primary repayment source such as insufficient cash flow from operations to service the debt. However, other weaknesses such as limited paying capacity of the obligor or the collateral pledged could justify a substandard grade. Substandard loans must have a well-defined weakness, or weaknesses that jeopardize the liquidation of the debt. (iv) Credits purchased from third parties are recorded at their estimated fair value at the acquisition date and are classified as PCI loans if the loans reflect credit deterioration since origination and it is probable at acquisition that the Company will be unable to collect all contractually required payments (see Note 1 – Nature of Operations and Summary of Significant Accounting Policies – Certain Acquired Loans). (v) A loan classified as doubtful has all the weaknesses of a substandard loan with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. A doubtful loan has a high probability of total or substantial loss, but because of specific pending events that may strengthen the asset, its classification as loss is deferred. Doubtful borrowers are usually in default, lack adequate liquidity or capital, and lack the resources necessary to remain an operating entity. Because of high probability of loss, non-accrual status is required on doubtful loans. (vi) Loans classified as loss are considered uncollectible and of such little value that their continuance as banking assets are not warranted. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future. With loans classified as loss, the underlying borrowers are often in bankruptcy, have formally suspended debt repayments, or have otherwise ceased normal business operations. Once an asset is classified as loss, there is little prospect of collecting either its principal or interest. When access to collateral, rather than the value of the collateral, is a problem, a less severe classification may be appropriate.

The amount of the allowance represents management's best estimate of current expected credit losses on loans considering available information, from internal and external sources, relevant to assessing collectability over the loans' contractual terms, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals and modifications unless (i) management has a reasonable expectation that a loan to an individual borrower that is experiencing financial difficulty will be modified or (ii) such extension or renewal options are not unconditionally cancellable by us and, in such cases, the borrower is likely to meet applicable conditions and likely to request extension or renewal. Relevant available information includes historical credit loss experience, current conditions and reasonable and supportable forecasts, including U.S. Unemployment, GDP and Case-Shiller U.S National Home Price Index. While historical credit loss experience provides the basis for the estimation of expected credit losses, adjustments to historical loss information may be made for differences in current portfolio-specific risk characteristics, environmental conditions or other relevant factors. The allowance for credit losses is measured on a collective basis for portfolios of loans when similar risk characteristics exist. Credit loss expense related to loans reflects the totality of actions taken on all loans for a particular period including any necessary increases or decreases in the allowance related to changes in credit loss expectations associated with specific loans or pools of loans. Portions of the allowance may be allocated for specific credits; however, the entire allowance is available for any credit that, in management’s judgment, should be charged off. While management utilizes its best judgment and information available, the ultimate appropriateness of the allowance is dependent upon a variety of factors beyond our control, including the performance of our loan portfolio, the economy, changes in interest rates and the view of the regulatory authorities toward loan classifications. In calculating the allowance for credit losses, most loans are segmented into pools based upon similar characteristics and risk profiles. Common characteristics and risk profiles include the type/purpose of loan, underlying collateral, geographical similarity and historical/expected credit loss patterns. In developing these loan pools for the purposes of modeling expected credit losses, we also analyzed the degree of correlation in how loans within each portfolio respond when subjected to varying economic conditions and scenarios as well as other portfolio stress factors. For modeling purposes, we use loan call report codes to identify the pools of loans with similar risk characteristics. Loans that do not share risk characteristics are evaluated for expected credit losses on an individual basis and excluded from the collective evaluation. We periodically reassess each pool to ensure the loans within the pool continue to share similar characteristics and risk profiles and to determine whether further segmentation is necessary. We have elected to use the discounted cash flow (“DCF”) method for estimating accumulated credit losses for all loans except for consumer loans and leases. The DCF method allows for an effective incorporation of reasonable and supportable forecasts that can be applied in a consistent and objective manner. The method also aligns well with other calculations outside the accumulated credit loss estimations which mitigate model risk in other areas such as fair value or exit price notion calculations, interest rate risk calculations, profitability analysis, asset-liability management, and other forms of cash flow analysis. We have elected to use the weighted-average remaining maturity (“WARM”) method for consumer loans and leases. The long-term average loss rate is calculated and applied on a quarterly basis for the remaining life of the pool. Adjustments for economic expectations are made in the qualitative portion of the calculation. The long-term average loss rate is derived using peer data derived from the call report. There may be certain financial assets for which the expectation of credit loss is zero after evaluating historical loss information, making necessary adjustments for current conditions and reasonable and supportable forecasts, and considering any collateral or guarantee arrangements that are not free-standing contracts. A loan that is fully secured by cash or cash equivalents, such as certificates of deposit issued by the lending institution, would likely have zero credit loss expectations. Similarly, the guaranteed portion of a SBA loan or security purchased on the secondary market through the SBA’s fiscal and transfer agent would likely have zero credit loss expectations because these financial assets are unconditionally guaranteed by the U.S. government. Currently, the Company deducts the SBA guaranteed portion of financial assets from the individual asset balance. Management qualitatively adjusts model results for risk factors that are not considered within our modeling processes but are nonetheless relevant in assessing the expected credit losses within our loan pools. These qualitative factors (“Q-Factor”) and other qualitative adjustments may increase or decrease management's estimate of expected credit losses by a calculated percentage or amount based upon the estimated level of risk. The various risks that may be considered in making Q-Factor and other qualitative adjustments include, among other things, the impact of (i) changes in lending policies and procedures, including changes in underwriting standards and practices for collections, write-offs, and recoveries, (ii) actual and expected changes in international, national, regional, and local economic and business conditions and developments that affect the collectability of the loan pools, (iii) changes in the nature and volume of the loan pools and in the terms of the underlying loans, (iv) changes in the experience, ability, and depth of our lending management and staff, (v) changes in volume and severity of past due financial assets, the volume of non-accrual assets, and the volume and severity of adversely classified or graded assets, (vi) changes in the quality of our credit review function, (vii) changes in the value of the underlying collateral for loans that are non-collateral dependent, (viii) the existence, growth, and effect of any concentrations of credit and (ix) other factors such as the regulatory, legal and technological environments; competition; and events such as natural disasters or health pandemics. In some cases, management may determine that an individual loan exhibits unique risk characteristics which differentiate the loan from other loans within our loan pools. In such cases, the loans are evaluated for expected credit losses on an individual basis and excluded from the collective evaluation. Specific allocations of the allowance for credit losses are determined by analyzing the borrower’s ability to repay amounts owed, collateral deficiencies, the relative risk grade of the loan and economic conditions affecting the borrower’s industry, among other things. A loan is considered to be collateral dependent when, based upon management's assessment, the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. In such cases, expected credit losses are based on the fair value of the collateral at the measurement date, adjusted for estimated selling costs if satisfaction of the loan depends on the sale of the collateral. We reevaluate the fair value of collateral supporting collateral dependent loans on a quarterly basis. The fair value of real estate collateral supporting collateral dependent loans is evaluated using a methodology that is consistent with the Uniform Standards of Professional Appraisal Practice. The fair value of collateral supporting collateral dependent construction loans is based on an “as is” valuation.

GAAP prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Benefits from tax positions should be recognized in the consolidated financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of cumulative benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met. GAAP also provides guidance on the accounting for and disclosure of unrecognized tax benefits, interest and penalties.

FHLB Advances and Other Borrowings	7. FHLB Advances and Other Borrowings FHLB Advances The FHLB allows the Company to borrow on a blanket floating lien status collateralized by FHLB stock and real estate loans. As of March 31, 2024 and December 31, 2023, borrowing capacity available under this arrangement was $ 643.9 million and $ 565.1 million, respectively. The Company had no FHLB advances outstanding at March 31, 2024 and December 31, 2023. Letters of credit with the FHLB in the amount of $ 428.6 million were issued at March 31, 2024. The letters of credit are used to collateralize public fund deposit accounts in excess of FDIC insurance limits and have expirations ranging from April 2024 through July 2025 . Line of Credit - Senior Debt The Company has a $ 55.0 million revolving line of credit facility that was modified effective March 12, 2024, whereby the facility was increased by $ 5.0 million and the note rate was decreased to The Wall Street Journal US Prime Rate, as such changes from time to time, less 0.625 %, with a floor rate of 5.00 % per annum. Interest continues to be payable quarterly on the 10 th day of March, June, September and December through maturity date of March 10, 2026 . All principal and unpaid interest is due at maturity. The note is secured by 100 % of the outstanding stock of the Bank and is senior in rights to the subordinated debt described below. Prior to the modification, the $ 50.0 million facility was due on September 10, 2024 , and bore interest at The Wall Street Journal US Prime Rate, as such changes from time to time, plus 0.50 %, with a floor rate of 5.00 % per annum. At March 31, 2024 and December 31, 2023, the outstanding balance was $ 43.9 million and $ 38.9 million, respectively. Note Payable - Subordinated Debt O n March 31, 2022, the Company entered into Subordinated Note Purchase Agreements (the “Note Purchase Agreements”) with certain qualified institutional buyers and institutional accredited investors (the “Purchasers”) pursuant to which the Company issued and sold $ 82.3 million in aggregate principal amount of its 5.500 % Fixed-to-Floating Rate Subordinated Notes due 2032 (the “Notes”) in a private placement transaction in reliance on exemptions from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), pursuant to Section 4(a)(2) of the Securities Act and Regulation D thereunder. The Notes were issued by the Company to the Purchasers at a price equal to 100 % of their face amount. The Note Purchase Agreements contain certain customary representations, warranties and covenants made by the Company, on the one hand, and the Purchasers, severally and not jointly, on the other hand. The Notes are intended to qualify as Tier 2 capital for regulatory capital purposes, and the Company intends to use the net proceeds from the offering for general corporate purposes. The Notes were issued under an Indenture, dated as of March 31, 2022 (the “Indenture”), by and between the Company and UMB Bank, N.A., as trustee. The Notes will mature on April 1, 2032 . From and including March 31, 2022, to, but excluding, April 1, 2027 or the date of early redemption, the Company will pay interest on the Notes semi-annually in arrears on April 1 and October 1 of each year, commencing on October 1, 2022 , at a fixed interest rate of 5.500 % per annum. From and including April 1, 2027, to, but excluding, the maturity date or the date of early redemption (the “Floating Rate Period”), the Company will pay interest on the Notes at a floating interest rate. The floating interest rate will be reset quarterly, and the interest rate for any Floating Rate Period shall be equal to the then-current Three-Month Term Secured Overnight Financing Rate (“SOFR”) plus 315 basis points for each quarterly interest period during the Floating Rate Period. Interest payable on the Notes during the Floating Rate Period will be paid quarterly in arrears on January 1, April 1, July 1 and October 1, of each year, commencing on July 1, 2027. Notwithstanding the foregoing, in the event that Three-Month Term SOFR is less than zero, then Three-Month Term SOFR rate shall be deemed to be zero. On March 31, 2022, in connection with the issuance and sale of the Notes, the Company entered into Registration Rights Agreements with the Purchasers. Under the terms of the Registration Rights Agreements, the Company agreed to take certain actions to provide for the exchange of the Notes for subordinated notes that are registered under the Securities Act and have substantially the same terms as the Notes. The exchange offer under the Registration Rights Agreement was completed on July 19, 2022. The Company may, at its option, redeem the Notes (i) in whole or in part beginning with the interest payment date on April 1, 2027 , and on any interest payment date thereafter, or (ii) in whole, but not in part, upon the occurrence of a “Tier 2 Capital Event,” a “Tax Event,” or “Investment Company Event”. The redemption price for any redemption is 100 % of the principal amount of the Notes, plus accrued and unpaid interest thereon to, but excluding, the date of redemption. Any redemption of the Notes will be subject to the receipt of the approval of the Federal Reserve to the extent then required under applicable laws or regulations, including capital adequacy rules or regulations. There is no right of acceleration of maturity of the Notes in the case of default in the payment of principal of, or interest on, the Notes or in the performance of any other obligation of the Company under the Notes or the Indenture. The Indenture provides that holders of the Notes may accelerate payment of indebtedness only upon the Company’s bankruptcy, insolvency, reorganization, receivership or other similar proceedings. The Notes are general unsecured, subordinated obligations of the Company and rank junior to all of its existing and future Senior Indebtedness (as defined in the Indenture), including all of its general creditors. The Notes will be equal in right of payment with any of the Company’s existing and future subordinated indebtedness, and will be senior to the Company’s obligations relating to any junior subordinated debt securities. In addition, the Notes are effectively subordinated to all secured indebtedness of the Company, including without limitation, the Bank’s liabilities to depositors in connection with deposits in the Bank, to the extent of the value of the collateral securing such indebtedness. In connection with the above offering, the Company incurred approximately $ 2.1 million in debt issuance costs which will be amortized to interest expense on a straight-line basis over the ten-year life of the note. At March 31, 2024 and December 31, 2023, the Company had $ 82.3 million in outstanding principal and $ 1.7 million in unamortized debt issuance costs. Federal Reserve Borrower-in-Custody (BIC) Loan Pledge Arrangement During June 2023, the Federal Reserve Bank approved the Company to begin pledging, on a blanket floating lien status, its commercial and industrial loans under a Borrower-in-Custody (“BIC”) arrangement. The arrangement provides the Company with the ability to secure collateralized contingency funding from the Discount Window of the Federal Reserve Bank of Dallas. As of March 31, 2024 and December 31, 2023, total borrowing capacity under this arrangement was $ 1.3 billion and $ 1.2 billion, respectively. The Company had no advances outstanding under these lines as of March 31, 2024 or December 31, 2023. Federal Funds Lines of Credit At March 31, 2024 and December 31, 2023, the Company had federal funds lines of credit with commercial banks that provide for availability to borrow up t o an aggregate of $ 36.5 million. The Company had no advances outstanding under these lines at March 31, 2024 and December 31, 2023 .

Stock Options And Warrants [Abstract]
Stock Options and Warrants	8. Stock Options and Warrants 2013 Stock Option Plan In 2008 upon shareholder approval, the Bank adopted the 2008 Stock Option Plan. In 2013 upon formation of Third Coast Bancshares, Inc., the Company adopted the 2013 Stock Option Plan (the “2013 Plan”). All outstanding options from the 2008 Stock Option Plan were grandfathered into the 2013 Plan. The 2013 Plan permits the grant of stock options for up to 500,000 shares of common stock from time to time during the term of the plan, subject to adjustment upon changes in capitalization. Under the 2013 Plan, the Bank may grant either incentive stock options or nonqualified stock options to eligible directors, executive officers, key employees and non-employee shareholders of the Bank. At March 31, 2024, there were no shares remaining available for g rant for future awards as all outstanding options under the 2013 Plan were grandfathered into the 2019 Omnibus Incentive Plan (see 2019 Omnibus Incentive Plan). Awards outstanding under the 2013 Plan remain in full force and effect, according to their respective terms. 2019 Omnibus Incentive Plan On May 29, 2019, the Company’s shareholders approved the Third Coast Bancshares, Inc. 2019 Omnibus Incentive Plan (the “2019 Plan”), which was previously approved by the Company’s board of directors. Under the 2019 Plan, the Company may issue stock options, stock appreciation rights, restricted stock, restricted stock units, stock bonuses, other stock-based awards, cash awards, and dividend equivalents. On May 20, 2021, the Company’s shareholders approved an amendment to the 2019 Plan such that the maximum number of shares reserved for issuance under the 2019 Plan was increased by an additional 500,000 shares. The maximum aggregate number of shares of common stock that may be issued under the 2019 Plan is equal to the sum of (i) 800,000 shares of common stock, (ii) the total number of shares remaining available for new awards under the 2013 Plan as of May 29, 2019, which was 152,750 shares of common stock, and (iii) any shares subject to outstanding stock options issued under the 2013 Plan to the extent that (A) any such award is forfeited or otherwise terminates or is cancelled without the delivery of shares of common stock, or (B) shares of common stock are withheld from any such award to satisfy any tax or withholding obligation, in which case the shares of common stock covered by such forfeited, terminated or cancelled award or which are equal to the number of shares of common stock withheld, will become available for issuance under the 2019 Plan. At March 31, 2024, there were 84,189 shares rema ining available for grant for future awards under the 2019 Plan. 2017 Non-Employee Director Stock Option Plan In December 2017, the Bank adopted the 2017 Non-Employee Director Stock Option Plan (the “Director Plan”). The Director Plan originally authorized the grant of stock options for up to 100,000 shares of common stock to non-employee directors of the Company pursuant to the terms of the Director Plan. During July 2018, the Company's board of directors approved the grant of stock options for 50,000 additional shares of common stock under the Director Plan, such that the Director Plan permitted the grant of stock options for up to 150,000 shares of common stock. On January 1, 2021, the Director Plan was amended and subsequently approved by the Company’s board of directors such that the aggregate number of shares of common stock to be issued pursuant to options shall not exceed 187,000 shares. Options are generally granted with an exercise price equal to the market price of the Company’s stock at the date of the grant. Option awards generally vest based on five years of continuous service and have 10-year contractual terms for non-controlling participants as defined by the Director Plan. Other grant terms can vary for controlling participants as defined by the Director Plan. At March 31, 2024, there w ere 13,806 shares remain ing available for grant for future awards under the Director Plan. 2020 Heritage Stock Option Plan On January 1, 2020, the Company acquired a stock option plan which originated under Heritage Bancorp, Inc. as part of a merger of the two companies. The options granted to employees must be exercised within 10 years from the date of grant and vesting schedules are determined on an individual basis. At merger date, 109,908 outstanding options became fully vested and were converted to options to purchase 97,821 shares of the Company’s common stock at an exchange ratio of 0.89 , which was equal to the acquisition exchange rate for common shares. At March 31, 2024, no shares were available for grant for future awards. Stock Options During the three months ended March 31, 2024, the Company granted stock options under the 2019 Plan to certain directors, executive officers and other key employees of the Company. These stock options vest ratably over five years and have a 10-year contractual term. Options granted during the three months ended March 31, 2024 were granted with an exercise price ranging from $ 19.50 to $ 19.59 . Options granted during the three months ended March 31, 2023 were granted with an exercise price ranging f rom $ 18.06 to $ 18.99 . The fair value of each option award is estimated on the grant date using the Black-Scholes option-pricing model with the following assumptions used for the options granted in the three months ended March 31, 2024: risk-free interest rate ranging from 3.84 % to 3.95 %, dividend yield of 0.00 %; estimated volatility ranging from 23.42 % to 23.49 %; and expected lives of options of 7.5 years. The following assumptions were used for options granted in the three months ended March 31, 2023: risk-free interest rate ranging from 3.42 % to 4.14 %, dividend yield of 0.00 %; estimated volatility ranging from 17.81 % to 17.89 %; and expected lives of options of 7.5 years. Expected volatilities are based on historical volatilities of the Company’s common stock and similar peer group averages. For the three months ended March 31, 2024 and 2023, the Company recognized share-based compensatio n expense of $ 124,000 and $ 142,000 , respectively, associated with stock options. As of March 31, 2024, there was approximately $ 1.4 million of unrecognize d compensation costs related to non-vested stock options that is expected to be recognized over the remaining vesting periods. Forfeitures are recognized as they occur.

Leases [Abstract]
Leases	9. Leases Operating Leases The Company leases certain office space, stand-alone buildings and equipment which are recognized as operating lease right-of-use (“ROU”) assets and operating lease liabilities and are included in other assets and other liabilities in the consolidated balance sheets. Lease liabilities represent the Company's liability to make lease payments under these leases, on a discounted basis. For leases with renewal options available, the Company evaluates each lease to determine if exercise of the renewal option is reasonably certain. As of March 31, 2024, the Company's operating lease ROU asset and operating lease liability totaled $ 20.7 million and $ 21.6 million, respe ctively. In order to calculate its ROU assets and lease liabilities, ASC Topic 842 requires the Company to use the rate of interest implicit in the lease when readily determinable. If the rate implicit in the lease is not readily determinable, the Company is required to use its incremental borrowing rate, which is the rate of interest the Company would have to pay to borrow on a collateralized basis over a similar term in a similar economic environment. The Company was unable to determine the implicit interest rate in any of the leases and therefore used its incremental borrowing rate. As of March 31, 2024, the weighted-average discount rate for the Com pany's operating leases was 4.63 %. The Company's lease terms range from less than one year to one hundred forty-four months . The weighted-average remaining term of the leases was 8.43 years. Lease costs for the three months ended March 31, 2024 and 2023 were as follows: For the Three Months Ended March 31, (Dollars in thousands) 2024 2023 Operating lease cost $ 1,170 $ 982 Short-term lease cost 10 62 Total lease cost $ 1,180 $ 1,044 A schedule of the Company's lease liabilities by contractual maturity for operating leases with initial or remaining terms in excess of one year for each year through 2029 and thereafter is presented below: (Dollars in thousands) March 31, 2024 2024 (nine months remaining) $ 2,371 2025 3,250 2026 3,324 2027 3,360 2028 3,169 2029 and thereafter 11,716 Total undiscounted lease liability 27,190 Less: Discount on cash flows ( 4,475 ) Leases signed, but not yet commenced ( 1,068 ) Total operating lease liability $ 21,647

Financial Instruments With Off Balance Sheet Risk [Abstract]
Financial Instruments with Off Balance Sheet Risk	10. Financial Instruments with Off-Balance Sheet Risk The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the balance sheet. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for unfunded lines of credit, commitments to extend credit and standby letters of credit is represented by the contractual notional amount of these instruments. The Company generally uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The following financial instruments were outstanding whose contract amounts represent credit risk: (Dollars in thousands) March 31, 2024 December 31, 2023 Commitments to extend credit $ 1,421,293 $ 1,352,147 Standby letters of credit 25,702 26,850 Total $ 1,446,995 $ 1,378,997 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Management evaluates each customer’s credit-worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary upon extension of credit, is based on management’s credit evaluation of the borrower. Standby letters of credit are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. Standby letters of credit generally have fixed expiration dates or other termination clauses and may require payment of a fee. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank's policy for obtaining collateral and the nature of such collateral is essentially the same as that involved in making commitments to extend credit. The allowance for credit losses on off-balance-sheet credit exposures is a liability account, calculated in accordance with ASC 326, representing expected credit losses over the contractual period for which we are exposed to credit risk resulting from a contractual obligation to extend credit. Off-balance sheet credit exposures primarily consist of amounts available under outstanding lines of credit and letters of credit detailed in the table above, less those obligations which the Company has the unconditional right to cancel. No allowance is recognized if the issuer has an unconditional right to cancel the obligation. The amount of the allowance represents management's best estimate of expected credit losses on commitments expected to be funded over the contractual life of the commitment. At March 31, 2024 and December 31, 2023, the allowance for credit losses related to off-balance sheet exposures was $ 2.1 million and $ 2.4 million, respectively.

Fair Value Disclosures [Abstract]
Fair Value Measurements	11. Fair Value Measurements GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability shall not be adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing to transact. GAAP requires the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement costs). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, the authoritative guidance establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: • Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. • Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset and liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (for example, interest rates, volatilities, prepayment speeds, loss severities, credit risks and default rates) or inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 2 investments consist primarily of obligations of U.S. government sponsored enterprises and agencies, obligations of state and municipal subdivisions, corporate bonds and mortgage-backed securities. • Level 3 Inputs – Significant unobservable inputs that reflect an entity’s own assumptions that market participants would use in pricing the assets or liabilities. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Financial assets and financial liabilities measured at fair value on a recurring and nonrecurring basis include the following: Investment Securities Available-for-sale . Investment securities classified as available-for-sale are reported at fair value utilizing Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayments speeds, credit information, and the bond’s terms and conditions, among other things. Loans Held for Sale . Loans held for sale are reported at aggregate cost which has been deemed to be the equivalent of fair value using Level 3 inputs. Loans Evaluated Individually for Expected Credit Losses . Individually evaluated loans are reported at the estimated fair value of the underlying collateral. Collateral values are estimated using Level 2 inputs based on observable market data or independent appraisals using Level 3 inputs. Derivative Instruments . The estimated fair value of interest rate derivative positions are obtained from a pricing service that provides the swaps’ unwind value using Level 2 inputs. There were no transfers between levels during the three month period ended March 31, 2024 or during the year ended December 31, 2023. The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value as of March 31, 2024 and December 31, 2023: Fair Value Measurements Using (Dollars in thousands) Level 1 Inputs Level 2 Inputs Level 3 Inputs Total Fair Value At March 31, 2024: Securities available-for-sale: U.S government and agency securities $ — $ 19,176 $ — $ 19,176 State and municipal securities — 1,006 — 1,006 Mortgage-backed securities and collateralized mortgage obligations — 126,047 — 126,047 Corporate bonds — 100,062 — 100,062 Total investment securities available-for-sale $ — $ 246,291 $ — $ 246,291 Derivative assets: Cash flow hedges $ — $ 2,595 $ — $ 2,595 Pass-through interest rate swaps — 8,203 — 8,203 Risk participation agreements — 14 — 14 Pay-fixed interest rate swaps — 203 — 203 Total derivative assets $ — $ 11,015 $ — $ 11,015 Derivative liabilities: Pass-through interest rate swaps $ — $ 8,203 $ — $ 8,203 Risk participation agreements — 2 — 2 Pay-fixed interest rate swaps — 48 — 48 Total derivative liabilities $ — $ 8,253 $ — $ 8,253 At December 31, 2023: Securities available-for-sale: U.S. government and agency securities $ — $ 3,991 $ — $ 3,991 Mortgage-backed securities and collateralized mortgage obligations — 78,533 — 78,533 Corporate bonds — 95,563 — 95,563 Total investment securities available-for-sale $ — $ 178,087 $ — $ 178,087 Derivative assets: Pass-through interest rate swaps $ — $ 8,774 $ — $ 8,774 Risk participation agreements — 6 — 6 Pay-fixed interest rate swaps — 48 — 48 Total derivative assets $ — $ 8,828 $ — $ 8,828 Derivative liabilities: Cash flow hedges $ — $ 1,541 $ — $ 1,541 Interest rate swaps — 8,774 — 8,774 Risk participation agreements — 20 — 20 Pay-fixed interest rate swaps — 352 — 352 Total derivative liabilities $ — $ 10,687 $ — $ 10,687 Certain financial assets and financial liabilities are measured at fair value on a nonrecurring basis, that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Financial assets and financial liabilities measured at fair value on a non-recurring basis include the following at March 31, 2024 and December 31, 2023: Loans Evaluated Individually for Expected Credit Losses. At March 31, 2024, collateral dependent loans with carrying values of $ 15.6 million were reduced by specific valuation allowances totaling $ 5.2 million resulting in a net fair value of $ 10.4 million based on Level 3 inputs. At December 31, 2023, collateral dependent loans with carrying values of $ 10.1 million were reduced by specific valuation allowances totaling $ 4.4 million resulting in a net fair value of $5 .7 million based on Level 3 inputs. Non-financial assets measured at fair value on a non-recurring basis may include certain foreclosed assets which, upon initial recognition, are remeasured and reported at fair value through a charge-off to the allowance for credit losses and certain foreclosed assets which, subsequent to their initial recognition, are remeasured at fair value through a write-down included in current earnings. The fair value of a foreclosed asset is estimated using Level 2 inputs based on observable market data or Level 3 inputs based on customized discounting criteria. The Company did no t have any foreclosed assets for fair value measurement as of March 31, 2024 or December 31, 2023. For the Company, as for most financial institutions, substantially all of its assets and liabilities are considered financial instruments as defined. Many of the Company’s financial instruments, however, lack an available trading market as characterized by a willing buyer and willing seller engaging in an exchange transaction. The estimated fair value amounts of financial instruments have been determined by the Company using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. In addition, reasonable comparability between financial institutions may not be likely due to the wide range of permitted valuation techniques and numerous estimates that must be made given the absence of active secondary markets for many of the financial instruments. This lack of uniform valuation methodologies also introduces a greater degree of subjectivity to these estimated fair values. Financial instruments with stated maturities have been valued using a present value discounted cash flow with a discount rate approximating current market rates for similar assets and liabilities. Financial instrument assets with variable rates and financial instrument liabilities with no stated maturities have an estimated fair value equal to both the amount payable on demand and the carrying value. The carrying value and the estimated fair value of the Company’s contractual off-balance sheet unfunded lines of credit, loan commitments and letters of credit, which are generally priced at market at the time of funding, are not material. The estimated fair values and carrying values of all financial instruments under current authoritative guidance, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value are as follows: March 31, 2024 December 31, 2023 (Dollars in thousands) Carrying Estimated Carrying Estimated Financial assets: Level 2 inputs Cash and cash equivalents $ 498,260 $ 498,260 $ 411,845 $ 411,845 Investment securities available-for-sale 246,291 246,291 178,087 178,087 Non-marketable securities 16,095 16,095 16,041 16,041 Accrued interest receivable 25,769 25,769 23,120 23,120 Bank-owned life insurance 66,443 66,443 65,861 65,861 Derivative assets 11,015 11,015 8,828 8,828 $ 863,873 $ 863,873 $ 703,782 $ 703,782 Level 3 inputs Loans, net $ 3,708,038 $ 3,631,387 $ 3,601,766 $ 3,532,270 Financial liabilities: Level 2 inputs Deposits $ 4,050,672 $ 4,070,158 $ 3,803,148 $ 3,821,744 Accrued interest payable 3,927 3,927 4,794 4,794 Note payable and line of credit 124,480 124,480 119,428 119,428 Derivative liabilities 8,253 8,253 10,687 10,687 $ 4,187,332 $ 4,206,818 $ 3,938,057 $ 3,956,653

Risks and Uncertainties [Abstract]
Significant Group Concentrations of Credit Risk	12. Significant Group Concentrations of Credit Risk The Company’s principal business activities are with customers primarily located within Texas. Such customers are normally also depositors of the Company. In addition, the Company employs a national wholesale deposit strategy to attract and maintain large, relatively low-cost stable deposits through a number of core, fiduciary and institutional deposit programs. The distribution of commitments to extend credit approximates the distribution of loans outstanding. The contractual amounts of credit related financial instruments such as commitments to extend credit and credit card arrangements represent the amounts of potential accounting loss should the contract be fully drawn upon, the customer default, and the value of any existing collateral become worthless. At March 31, 2024 and December 31, 2023, the Company had federal funds sold aggregating approximately $ 130.4 million and $ 114.9 million, respectively, which represents concentrations of credit risk. The Company also maintains deposit balances with other financial institutions that exceed FDIC coverage and also represent credit risk. These balances were approximately $ 209.6 million and $ 262.1 million, respectively, at March 31, 2024 and December 31, 2023. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk on cash and cash equivalents.

Employee Benefit Plans	13. Employee Benefit Plans In 2009, the Company adopted the Third Coast Bank, SSB 401(k) Plan (the “Plan”) covering substantially all employees. Employees may elect to defer a percentage of their compensation subject to certain limits based on federal tax laws. The Company may make a discretionary match of employees’ contributions based on a percentage of salary contributed by participants. Effective July 1, 2022, the Company amended the Third Coast Bank, SSB 401(k) Plan and merged that plan into the Third Coast Bank, SSB Employee Stock Ownership Plan (the “Merged Plan”). In connection with this amendment and plan merger, on July 1, 2022, the Company registered an aggregate of 400,000 shares of the Company's common stock, par value $ 1.00 per share, for issuance to the Merged Plan in connection with elections by participants to allocate a portion of their plan account balances (up to the limits prescribed under the Merged Plan) to the Company stock fund investment option. The number of shares held by the ESOP immediately prior to the plan merger was 149,461 shares. Under the Merged Plan, discretionary contributions made by the Company will be invested at the direction of the plan participant, in accordance with participant plan elections. For the three months ended March 31, 2024 and 2023, Company contributions to the Merged Plan were appr oximately $ 388,000 a nd $ 332,000 , respectively. Administrative expense related to the Merged Plan for the same three month periods totaled approximatel y $ 19,000 and $ 25,000 , respectively. Th e costs were included in salaries and employee benefits in the accompanying consolidated statements of income.

Shareholders’ Equity and Regulatory Matters	15. Shareholders’ Equity and Regulatory Matters Amendment to Certificate of Formation On May 25, 2023, the shareholders of the Company approved the amendment and restatement (the “Amendment”) of Article VI of the Company's first amended and restated certificate of formation to authorize a new class of non-voting common stock, par value $ 1.00 per share. Under the terms of the Amendment, the Company is authorized to issue 54,500,000 shares of capital stock, consisting of 50,000,000 shares of common stock, par value $ 1.00 per share, 3,500,000 shares of non-voting common stock, par value $ 1.00 per share, and 1,000,000 shares of preferred stock, par value $ 1.00 per share. The shares of capital stock may be issued as authorized by the board of directors of the Company without the approval of its shareholders, except as otherwise provided by governing law, rule or regulation or as set forth in the certificate of formation, as amended. The Amendment became effective upon the filing of the Certificate of Amendment to the Certificate of Formation of the Company with the Secretary of State of the State of Texas on May 25, 2023. Preferred Stock On September 30, 2022, the Company adopted resolutions creating Series A Convertible Non-Cumulative Preferred Stock (“Series A Preferred Stock”) and Series B Convertible Perpetual Preferred Stock, with 69,400 shares authorized for each series. Preferred Stock - Private Placement On September 30, 2022, the Company completed a private placement of (i) 69,400 shares of Series A Preferred Stock, with a liquidation preference of $ 1,000 per share, and (ii) the Preferred Warrants at an exercise price equal to $ 22.50 per share, for aggregate gross proceeds of $ 69.4 million before deducting placement fees and offering expenses. Aggregate net proceeds were $ 66.2 million after deducting placement fees and offering expenses of $ 3.2 million. The securities sold in the private placement were sold only to accredited investors and were issued without registration under the Securities Act, in reliance upon the exemption provided under Section 4(a)(2) of the Securities Act and Regulation D promulgated thereunder as securities offered and sold only to accredited investors (as defined in Rule 501(a) of Regulation D under the Securities Act) in a transaction not involving any public offering. Officers and directors of the Company purchased $ 2.7 million of the Series A Preferred Stock. Regulatory Matters On March 13, 2024, the Bank completed its conversion from a Texas state savings bank to a Texas banking association. As a result of the conversion, the Texas Department of Banking is the Bank’s primary state regulator and the Federal Reserve is the Bank’s primary federal regulator. The Federal Reserve continues to be the Company’s primary federal regulator. The Bank remains as a member of the Federal Reserve System. The Company and Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory (and possibly additional discretionary) actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and Bank must meet specific capital guidelines that involve quantitative measures of the Company and Bank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Company and Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and Bank to maintain minimum amounts and ratios (set forth in the table below) of total, Tier I capital, and Common Equity Tier I capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier I capital (as defined) to average assets (as defined). Management believes, as of March 31, 2024 and December 31, 2023, the Company and Bank meet all capital adequacy requirements to which it is subject. Financial institutions are categorized as well capitalized or adequately capitalized, based on minimum total risk-based, Tier I risk-based and Tier I leverage ratios as set forth in the tables below. As shown below, the Bank’s capital ratios exceed the regulatory definition of well capitalized as of March 31, 2024 and December 31, 2023. Based upon the information in its most recently filed call report, the Bank continues to meet the capital ratios necessary to be well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since March 31, 2024 that management believes have changed the Bank’s category. A comparison of actual capital amounts and ratios to required capital amounts and ratios for the Company and Bank are presented in the following table. The Company began reporting ratios beginning March 31, 2023 in accordance with the regulatory framework. Capital levels required to be well capitalized are based upon prompt corrective action regulations.

Earnings Per Share [Abstract]
Earnings Per Common Share	16. Earnings Per Common Share Basic earnings per common share is computed by dividing net earnings allocated to common stock by the weighted-average number of common shares outstanding during the applicable period. Diluted earnings per common share is computed by using the net earnings allocated to common stock plus dividends on dilutive convertible preferred stock, divided by the sum of 1) the weighted-average number of shares determined for the basic earnings per common share computation, 2) the dilutive effect of stock compensation using the treasury stock method, and 3) the dilutive effect of convertible preferred stock using the if-converted method.

Derivative Financial Instruments	17. Derivative Financial Instruments Cash Flow Hedges As part of its hedging strategy, the Company entered into two five-year pay-fixed interest rate swap agreements during December 2023. The instruments have notional amounts of $ 100 million each with pay-fixed interest rates of 3.718 % and 3.473 %, respectively. The instruments are designated as cash flow hedges, and changes in fair value are recognized in other comprehensive income. The facilities are scheduled to mature on December 6, 2028 and December 21, 2028 , respectively. During March 2023 and as part of our hedging strategy, the Company entered into a five-year pay-fixed interest rate swap agreement with a notional amount of $ 200 million. The facility, which was scheduled to mature on March 31, 2028 , was discontinued on May 26, 2023, and a gain of $ 5.0 million was recognized by the Company. The gain is being accreted from other comprehensive income, net of deferred taxes, into interest expense through the maturity date of the contract. During July 2022, the Company entered into a five-year pay-fixed interest rate swap agreement with a notional amount of $ 200 million on its floating rate deposits. The facility, which was designated as a cash flow hedge, was discontinued on August 24, 2022, and a gain on the terminated hedge of $ 3.0 million was recognized by the Company. The gain is being accreted from other comprehensive income, net of deferred taxes, into interest expense through the maturity date of the contract, or July 9, 2027 . On February 18, 2021, a $ 100.0 million pay-fixed interest rate swap facility designated as a cash flow hedge was discontinued and a gain on the terminated hedge of $ 945,000 was recognized by the Company. The gain is being accreted from other comprehensive income, net of deferred taxes, into interest expense through the maturity date of the contract, or September 4, 2025 . For the three months ended March 31, 2024 and 2023, appro ximately $ 445,000 and $ 206,000 , respectively, was reclassified out of accumulated other comprehensive income and recognized as a reduction of interest expense on discontinued hedges. Fair Value Hedges The Company offers certain interest rate swap products directly to its qualified commercial banking customers. These financial instruments are not designated as hedging instruments. The interest rate swap derivative positions relate to transactions in which the Company enters into an interest rate swap with a customer, while at the same time entering into an offsetting interest rate swap with another financial institution. An interest rate swap transaction allows customers to effectively convert a variable rate loan to a fixed rate. In connection with each swap, the Company agrees to pay interest on a notional amount at a variable interest rate and receive interest from the customer on a similar notional amount at a fixed interest rate. At the same time, the Company agrees to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. Because the Company acts as an intermediary for its customer, changes in the fair value of the underlying derivative contracts are designed to offset each other and would not significantly impact the Company’s operating results except in certain situations where there is a significant deterioration in the customer’s credit worthiness or that of the counterparties. At March 31, 2024, no such deterioration was determined by management. The Company also offers one-way interest rate swap products to its customers. Under this type of arrangement, the Company extends a conventional fixed-rate loan to the borrower and then subsequently hedges the interest rate risk of that loan by entering into a swap for its own balance sheet to convert the fixed-rate loan to a synthetic floating rate asset. These types of swaps lock in the Company's spread over its cost of funds for the life of the loan. For some of its loan participation facilities, the Company enters into RPAs with other banks in order to hedge or share a portion of the risk of borrower default related to the interest rate swap on a participated loan. All derivatives are carried at fair value in either derivative assets or derivative liabilities in the accompanying consolidated balance sheets. At March 31, 2024, the Company's derivative assets and liabilities totaled $ 11.0 million and $ 8.3 million, respectively.

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations Third Coast Bancshares, Inc. (“Bancshares”), through its subsidiary, Third Coast Bank, a Texas banking association (the “Bank”), and the Bank’s subsidiary, Third Coast Commercial Capital, Inc. (“TCCC”), (collectively known as the “Company,” “we,” “us” or “our”), provide general consumer and commercial banking service s through 17 branch offices locate d in the Greater Houston, Dallas-Fort Worth, and Austin-San Antonio markets. Branch locations include: Humble, Kingwood, Beaumont, Port Arthur, Houston-Galleria, Conroe, Pearland, Lake Jackson, Dallas, Fort Worth, Plano, Detroit, La Vernia, Nixon, Austin, Georgetown and San Antonio. The Bank is engaged in traditional community banking activities, which include commercial and retail lending, deposit gathering, and investment and liquidity management activities. The Bank’s primary deposit products are demand deposits, money market accounts and certificates of deposit; its primary lending products are commercial business and real estate, residential construction, real estate mortgage and consumer loans. TCCC engages in accounts receivable factoring activities. The Company is subject to the regulations of certain government agencies and undergoes periodic examinations by those regulatory authorities.
Basis of Presentation	Basis of Presentation The unaudited consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information, reporting practices prescribed by the banking industry, and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements and should be read in conjunction with the Company's annual consolidated financial statements for the years ended December 31, 2023 and 2022 included in the Company's Annual Report on Form 10-K filed with the SEC on March 7, 2024. The December 31, 2023 consolidated balance sheet has been derived from the audited financial statements for the year ended December 31, 2023. In the opinion of management, all adjustments that were recurring in nature and considered necessary have been included for fair presentation of the Company’s financial position and results of operations. Operating results for the three months ended March 31, 2024 are not necessarily indicative of results that may be expected for the full year ending December 31, 2024. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates. Material estimates that are included in the financial statements include the allowance for credit losses, the valuation of goodwill and other intangible assets and the fair value of financial instruments. The accompanying unaudited consolidated financial statements include the accounts of Bancshares, the Bank, and TCCC. All significant intercompany transactions and balances have been eliminated in consolidation. The Company has evaluated subsequent events for potential recognition and/or disclosure through the date the consolidated financial statements were issued.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash, deposits with other financial institutions that have initial maturities of less than 90 days when acquired by the Company and federal funds sold.
Investment Securities Available For Sale	Investment Securities Available-For-Sale Investment securities available-for-sale consist of bonds, notes, and debentures that are not classified as trading securities or held-to-maturity securities. Investment securities available-for-sale are held for indefinite periods of time and carried at fair value, with the unrealized holding gains and losses reported as a component of other comprehensive income, net of tax. Management determines the appropriate classification of investment securities at the time of purchase.
Loans	Loans Loans are stated at the amount of unpaid principal, reduced by unearned income and an allowance for credit losses (“ACL”). Interest on loans is recognized using the effective interest method and includes amortization of deferred loan origination fees and costs over the life of the loans. The accrual of interest on loans is discontinued when there is a clear indication that the borrower’s cash flow may not be sufficient to meet payments as they become due, which is generally when a loan is 90 days past due. When a loan is placed on non-accrual status, all previously accrued and unpaid interest is reversed. Interest income is subsequently recognized on a cash basis as long as the remaining book balance of the asset is deemed to be collectible. If collectability is questionable, then cash payments are applied to principal. A loan is placed back on accrual status when both principal and interest are current and it is probable that the Company will be able to collect all amounts due (both principal and interest) according to the terms of the loan agreement. From time to time, the Company modifies its loan agreement with a borrower. The loan refinancing and restructuring guidance is considered for each loan modified to determine whether a modification results in a new loan or a continuation of an existing loan. In some cases, the loan may be considered restructured if the borrower is experiencing financial difficulties and the loan has been modified. Loan modifications to borrowers experiencing financial difficulty may be in the form of principal forgiveness, an interest rate reduction, an other-than-insignificant payment delay, or a term extension or a combination thereof, among other things. The Company has certain lending policies and procedures in place that are designed to maximize loan income with an acceptable level of risk. Management reviews and approves these policies and procedures on a regular basis and makes changes as appropriate. Management receives frequent reports related to loan originations, quality, concentrations, delinquencies, non-performing, and potential problem loans. Diversification in the loan portfolio is a means of managing risk associated with fluctuations in economic conditions, both by type of loan and geography. Commercial loans are underwritten after evaluating and understanding the borrower’s ability to operate profitably and effectively. Underwriting standards are designed to determine whether the borrower possesses sound business ethics and practices and to evaluate current and projected cash flows to determine the ability of the borrower to repay their 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. Most commercial loans are secured by the assets being financed or other business assets, such as accounts receivable or inventory, and include personal guarantees. Real estate loans are also subject to underwriting standards and processes similar to commercial and agricultural loans. These loans are underwritten primarily based on projected cash flows and, secondarily, as loans secured by real estate. The repayment of real estate loans is generally largely dependent on the successful operation of the property securing the loans or the business conducted on the property securing the loan. Real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. The properties securing the Company’s real estate portfolio are generally diverse in terms of type and geographic location primarily throughout the Greater Houston, Dallas, and Austin-San Antonio metropolitan areas. This diversity helps reduce the exposure to adverse economic events that affect any single market or industry. Generally, real estate loans are owner occupied which further reduces the Company’s risk. Agricultural loans are subject to underwriting standards and processes similar to commercial loans. Agricultural loans are primarily made based on the identified cash flows of the borrower and, secondarily, on the underlying collateral provided by the borrower. Most agricultural loans are secured by the agriculture related assets being financed, such as farmland, cattle, or equipment, and include personal guarantees. The Company utilizes methodical credit standards and analysis to supplement its policies and procedures in underwriting consumer loans. The Company’s loan policy addresses types of consumer loans that may be originated and the collateral, if secured, which must be perfected. The relatively smaller individual dollar amounts of consumer loans that are spread over numerous individual borrowers also minimizes the Company’s risk.
Allowance for Credit Losses	Allowance for Credit Losses As further discussed below, we adopted Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” on January 1, 2023. Accounting Standards Codification (“ASC”) Topic 326 (“ASC 326”) replaced the previous “incurred loss” model for measuring credit losses, which encompassed allowances for current known and inherent losses within the portfolio, with an “expected loss” model, which encompasses allowances for losses expected to be incurred over the life of the portfolio. The new current expected credit loss (“CECL”) model requires the measurement of all expected credit losses for financial assets measured at amortized cost and certain off-balance sheet credit exposures based on historical experience, current conditions, and reasonable and supportable forecasts. In connection with the adoption of ASC 326, we revised certain accounting policies and implemented certain accounting policy elections. The revised accounting policies are described below. Allowance For Credit Losses - Available-for-Sale Securities : For available-for-sale securities in an unrealized loss position, we first assess whether (i) we intend to sell or (ii) it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If either case is affirmative, any previously recognized allowances are charged-off and the security's amortized cost is written down to fair value through income. If neither case is affirmative, the security is evaluated to determine whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and any adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are 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, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Adjustments to the allowance are reported in our income statement as a component of provision for credit loss expense. Management has made the accounting policy election to exclude accrued interest receivable on available-for-sale securities from the estimate of credit losses. Available-for-sale securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by management or when either of the aforementioned criteria regarding intent or requirement to sell is met. Further information regarding our policies and methodology used to estimate the allowance for credit losses on available-for-sale securities is presented in Note 2 - Investment Securities Available-for-Sale. Prior to the adoption of ASU 2016-13, declines in the fair value of available-for-sale securities below their cost that were deemed to be other than temporary were reflected in earnings as realized losses. In estimating other-than-temporary impairment losses prior to January 1, 2023, management considered, among other things, (i) the length of time and the extent to which the fair value had been less than cost, (ii) the financial condition and near-term prospects of the issuer and (iii) the intent and our ability to retain our investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. Allowance for Credit Losses - Loans : The allowance for credit losses on loans is a contra-asset valuation account, calculated in accordance with ASC 326, that is deducted from the amortized cost basis of loans to present management's best estimate of the net amount expected to be collected. Loans are charged-off against the allowance when deemed uncollectible by management. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Adjustments to the allowance are reported in our income statement as a component of provision for credit loss expense. Management has made the accounting policy election to exclude accrued interest receivable on loans from the estimate of credit losses. Further information regarding our policies and methodology used to estimate the allowance for credit losses on loans is presented in Note 3 - Loans and Allowance for Credit Losses. Allowance For Credit Losses - Off-Balance Sheet Credit Exposures : The allowance for credit losses on off-balance sheet credit exposures is a liability account, calculated in accordance with ASC 326, representing expected credit losses over the contractual period for which we are exposed to credit risk resulting from a contractual obligation to extend credit. No allowance is recognized if we have the unconditional right to cancel the obligation. The allowance is reported as a component of other liabilities in our consolidated balance sheets. Adjustments to the allowance are reported in our income statement as a component of provision for credit loss expense. Further information regarding our policies and methodology used to estimate the allowance for credit losses on off-balance sheet credit exposures is presented in Note 10 - Financial Instruments with Off-Balance Sheet Risk.
Servicing Assets	Servicing Assets Certain Small Business Administration (“SBA”) loans are originated and intended for sale in the secondary market. They are carried at the lower of cost or estimated fair value in the aggregate. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. Gains or losses recognized upon the sale of loans are determined on a specific identification basis and are included in non-interest income. SBA loan transfers are accounted for as sales when control over the loan has been surrendered. Control over such loans is deemed to be surrendered when (i) the assets have been isolated from the Company, (ii) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (iii) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. The Company applies guidance issued by the Financial Accounting Standards Board (the “FASB”) that clarifies the accounting and reporting standards for transfers and servicing of financial assets and extinguishments of liabilities, in which, after a transfer of financial assets, an entity recognizes the financial and servicing assets it controls and liabilities it has incurred, derecognizes financial assets when control has been surrendered, and derecognizes liabilities when extinguished. To calculate the gain or loss on sale of loans, the Company’s investment in the loan is allocated among the retained portion of the loan, the servicing retained, the interest-only strip and the sold portion of the loan, based on the relative fair value of each portion. The gain or loss on the sold portion of the loan is recognized based on the difference between the sale proceeds and the allocated investment. As a result of the relative fair value allocation, the carrying value of the retained portion is discounted, with the discount accreted to interest income over the life of the loan. Servicing assets are amortized over an estimated life using a method that is in proportion to the estimated future servicing income. In the event future prepayments exceed management’s estimates and future cash flows are inadequate to cover the servicing asset, additional amortization would be recognized. The portion of servicing fees in excess of the contracted servicing fees is reflected as interest-only strips receivable, which are classified as available for sale and are carried at fair value. At March 31, 2024 and December 31, 2023, the Company was servicing loans previously sold of approximately $ 5.2 million and $ 4.8 million, respectively. The related servicing assets receivable were not material to the consolidated financial statements at March 31, 2024 and December 31, 2023
Premises and Equipment	Premises and Equipment Buildings, leasehold improvements, furniture and fixtures, and equipment are carried at cost, less accumulated depreciation, computed principally by the straight-line method based on the estimated useful lives of the related asset. Land is not depreciated. Major replacements and betterments are capitalized while maintenance and repairs are charged to expense when incurred. Gains or losses on dispositions are reflected in income as incurred. A small portion of the building’s floor space is currently leased out to tenants and recognized in income when earned.
Operating Leases	Operating Leases The Company leases certain office space, stand-alone buildings, and equipment which are recognized as operating lease right-of-use assets and operating lease liabilities in the consolidated balance sheets. Lease liabilities represent the Company's liability to make lease payments under these leases on a discounted basis and are amortized on a straight-line basis over the lease term for each related lease agreement. Right-of-use assets represent the Company's right to use, or control the use of, leased assets for their lease term and are amortized over the lease term of the related lease agreement. The Company does not recognize short-term operating leases on the consolidated balance sheets. A short-term lease has a term of 12 months or less and does not have a purchase option that is likely to be exercised.
Other Real Estate Owned	Other Real Estate Owned Other real estate owned represents properties acquired through or in lieu of loan foreclosure and are initially recorded at fair value less estimated costs to sell. Any write-down to fair value at the time of transfer to other real estate owned is charged to the allowance for credit losses. Costs of improvements are capitalized, whereas costs relating to holding other real estate owned and subsequent adjustments to the value are expensed. Operating and holding expenses of such properties, net of related income, are included in loan operations and other real estate owned expense on the accompanying consolidated statements of income. Gains or losses on dispositions are reflected in income as incurred. At March 31, 2024 and December 31, 2023, the Company had no other real estate owned.
Bank Owned Life Insurance	Bank-Owned Life Insurance The Company has purchased life insurance policies on certain employees. These bank-owned life insurance (“BOLI”) policies are recorded in the accompanying consolidated balance sheets at their cash surrender values. Income from these policies and changes in the cash surrender values are reported in the accompanying consolidated statements of income.
Non-Marketable Securities	Non-Marketable Securities The Company has restricted non-marketable securities which represent investment in Federal Home Loan Bank (“FHLB”) stock, Federal Reserve Bank (“FRB”) stock and Texas Independent Bank (“TIB”) stock. These investments are not readily marketable and are carried at cost, which approximates fair value. As a member of the FHLB, FRB and TIB systems, the Company is required to maintain minimum level of investments in stock, based on the level of borrowings and other factors. Both cash and stock dividends are reported as income.
Goodwill and Core Deposit Intangibles	Goodwill and Core Deposit Intangibles Goodwill represents the excess of cost over fair value of net assets acquired in a business combination. Goodwill is not amortized and is evaluated for impairment at least annually and on an interim basis if an event triggering impairment may have occurred. Core deposit intangibles are acquired customer relationships arising from bank acquisitions and are amortized on a straight-line basis over their estimated useful life of ten years. Core deposit intangibles are tested for impairment whenever events or changes in circumstances indicate the carrying amount of assets may not be recoverable from future undiscounted cash flows.
Derivative Financial Instruments	Derivative Financial Instruments Derivatives are recorded on our consolidated balance sheets as assets and liabilities measured at their fair value. The accounting for increases and decreases in the value of derivatives depends upon the use of the derivatives and whether the derivatives qualify for hedge accounting. At inception of the derivative, we designate the derivative as one of two types based on our intention and belief as to the likely effectiveness as a hedge. These two types are (1) a hedge of the fair value of a recognized asset or liability (“Fair Value Hedge”), and (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“Cash Flow Hedge”). For certain Fair Value Hedges, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item, are recognized in noninterest income or expense in our consolidated statements of income. Fair Value Hedge instruments offered by the Company which are included in noninterest income or expense include pass-through interest rate swap products to qualified commercial banking customers. Under this type of contract, the Company enters into an interest rate swap contract with a customer, while at the same time entering into an offsetting interest rate swap contract with a financial institution counterparty. Changes in the fair value of the underlying derivatives are designed to offset each other so they would not significantly impact the Company's operating results. The Company also enters into Risk Participation Agreements (“RPAs”) with other banks, primarily to share a portion of the risk of borrower default related to the interest rate swap on certain participated loans. Gains or losses on these types of derivatives are also included in noninterest income in our consolidated statements of income. A one-way interest rate swap is another type of Fair Value Hedge instrument offered to our customers. Under this type of arrangement, the Company extends a conventional fixed-rate loan to the borrower and then subsequently hedges the interest rate risk of that loan by entering into a swap for its own balance sheet to convert the fixed-rate loan to a synthetic floating rate asset. These types of swaps lock in the Company's spread over its cost of funds for the life of the loan. The gain or loss on this type of derivative is included in interest income in our consolidated statements of income. For a Cash Flow Hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. Cash Flow Hedge instruments include pay-fixed interest rate swap agreements with a financial institution counterparty. Net cash settlements on cash flow hedges are recorded in interest expense in the consolidated statements of income. Net cash settlements on one-way swap derivatives are recorded in interest income in the consolidated statements of income. Net cash settlements on pass-through interest rate swaps and RPAs are reported in noninterest income in the consolidated statements of income. Cash flows on hedges are classified in the cash flow statement the same as the items being hedged. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains and/or losses accumulated in other comprehensive income are amortized into earnings over the same period which the hedged transaction will affect earnings. We formally document the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions, at the inception of the hedging relationship. This documentation includes linking Cash Flow Hedges to specific assets and liabilities on the consolidated balance sheets or to forecasted transactions.
Business Combinations	Business Combinations The Company applies the acquisition method of accounting for business combinations. Under the acquisition method, the acquiring entity in a business combination recognizes 100% of the assets acquired and liabilities assumed at their acquisition date fair values. Management utilizes valuation techniques appropriate for the asset or liability being measured in determining these fair values. Any excess of the purchase price over amounts allocated to assets acquired, including identifiable intangible assets, and liabilities assumed is recorded as goodwill. Adjustments identified during the measurement period are recognized in the reporting period in which the adjustment amounts are determined. Acquisition related costs are expensed as incurred.
Comprehensive Income	Comprehensive Income Comprehensive income includes all changes in shareholders’ equity during a period, except those resulting from transactions with shareholders. Other than net income, comprehensive income includes the net effect of changes in the fair value of securities available-for-sale and certain derivative instruments designated as cash flow hedges.
Revenue from Contract with Customers	Revenues from Contracts with Customers The Company’s revenues from services such as deposit related fees, wire transfer fees, interchange fees on debit cards, ATM fees, and merchant fee income are presented within the service charges and fees category in the accompanying consolidated statements of income and are recognized as revenue as the Company satisfies its obligation to the customer.
Advertising and Marketing Expenses	Advertising and Marketing Expenses Advertising and marketing expenses consist of the Company’s advertising in its local market area and are expensed as incurred. Advertising and marketing expenses we re $ 355,000 and $ 686,000 for the three months ended March 31, 2024 and 2023, respectively. The expenses are included within noninterest expense in the accompanying consolidated statements of income.
Income Taxes	Income Taxes The Company files a consolidated income tax return with its subsidiary. Federal income tax expense or benefit is allocated on a separate return basis. Deferred tax assets and liabilities are reflected at currently enacted income tax rates applicable to the period in which the deferred tax assets and liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.
Share-Based Compensation	Share-Based Compensation Compensation expense for stock options is based on the fair value of the award on the measurement date, which, for the Company, is the date of the grant and is recognized ratably over the service period of the award. The fair value of stock options is estimated using the Black-Scholes option-pricing model.
Basic and Diluted Earnings Per Common Share	Basic and Diluted Earnings Per Common Share Earnings per common share is computed in accordance with ASC Topic 260, “Earnings Per Share.” Basic earnings per common share is computed by dividing net earnings allocated to common stock by the weighted-average number of common shares outstanding during the applicable period. Diluted earnings per common share is computed by using the net earnings allocated to common stock plus dividends on dilutive convertible preferred stock, divided by the sum of 1) the weighted-average number of shares determined for the basic earnings per common share computation, 2) the dilutive effect of stock compensation using the treasury stock method, and 3) the dilutive effect of convertible preferred stock using the if-converted method. A reconciliation of the weighted-average shares used in calculating basic earnings per common share and the weighted average common shares used in calculating diluted earnings per common share for the reported periods is provided in Note 16 – Earnings Per Common Share.
Reclassification	Reclassification Certain amounts in prior period consolidated financial statements may have been reclassified to conform to current period presentation. These reclassifications are immaterial and have no effect on net income, total assets or shareholders’ equity.
Recently Adopted and Issued Accounting Standards	Recently Adopted Accounting Standards: ASU 2016-13 - Current Expected Credit Losses In June 2016, the FASB issued ASU 2016-13, “Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 is effective for fiscal years beginning after December 15, 2022. ASU 2016-13 is intended to replace the incurred loss model for loans and other financial assets with an expected loss model, which is known as the current expected credit loss, or CECL, model. The change is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures such as loan commitments, standby letters of credit, financial guarantees, and other similar instruments. ASC 326 also made changes to the accounting for available-for-sale debt securities, specifically requiring credit losses for available-for-sale debt securities to be presented as an allowance rather than a write-down on available-for-sale debt securities. The Company adopted ASC 326 using the modified retrospective method for financial instruments measured at amortized cost and off-balance sheet credit exposure which requires reporting periods beginning after January 1, 2023 to be presented under ASC 326 guidance while prior period amounts to continue to be reported in accordance with previously applicable inherent risk methodology. Effective January 1, 2023, the Company adopted the standard and recorded an increase in the allowance for credit losses of $ 4.0 million and a net after-tax adjustment to retained earnings of $ 3.2 million for the cumulative effect of adopting ASC 326 for its loan portfolio. The following table illustrates the impact of ASC 326 on the allowance for credit losses by loan category at the January 1, 2023 adoption date: January 1, 2023 (Dollars in thousands) Post-ASC 326 Adoption Pre-ASC 326 Adoption Impact of ASC 326 Adoption Real estate loans: Non-farm non-residential owner occupied $ 5,097 $ 3,773 $ 1,324 Non-farm non-residential non-owner occupied 8,351 5,741 2,610 Residential 2,060 1,064 996 Construction, development & other 4,661 3,053 1,608 Farmland 94 82 12 Commercial & industrial 13,366 16,269 ( 2,903 ) Consumer 10 6 4 Municipal and other 712 363 349 $ 34,351 $ 30,351 $ 4,000 Recently Adopted Accounting Standards: ASU 2022-02 - Troubled Debt Restructurings and Vintage Disclosures The Company adopted ASU 2022-02, “Financial Instruments-Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures” on January 1, 2023 . The amendments in this update eliminate the accounting guidance for troubled debt restructurings (“TDRs”) by creditors in Subtopic 310-40, “Receivables-Troubled Debt Restructurings by Creditors,” while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, an entity must apply the loan refinancing and restructuring guidance to determine whether a modification results in a new loan or a continuation of an existing loan. The amendments of this update also require that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, “Financial Instruments-Credit Losses-Measured at Amortized Cost.” Gross write-off information must be included in the vintage disclosures and include the amortized cost basis of the financing receivable by credit-quality indicator and the class of the financing receivable by year or origination. See Note 3 - Loans and Allowance for Credit Losses for the vintage disclosures. Recently Issued Accounting Standards - Not Yet Adopted In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 720), Improvements to Income Tax Disclosures." ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. ASU 2023-09 requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. The standard is not expected to have a significant impact on the Company's financial statements.
