NATURE OF OPERATIONS AND SUMMAR

NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES	12 Months Ended
	Dec. 31, 2024
Accounting Policies [Abstract]
NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES	NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES Nature of Operations and Principles of Consolidatio n — The audited consolidated financial statements presented in this Annual Report on Form 10-K include the consolidated results of Stellar and its wholly-owned subsidiary, Stellar Bank, which are collectively herein referred to as “we,” “us”, “our” and the “Company.” The Company provides a diversified range of commercial banking services primarily to small- to medium-sized businesses. Intercompany transactions and balances are eliminated in consolidation under U.S. generally accepted accounting principles (“GAAP”). The Company derives substantially all of its revenues and income from the operation of the Bank. The Company is focused on delivering a wide variety of relationship-driven commercial banking products and community-oriented services tailored to meet the needs of small- to medium-sized businesses, professionals and individuals through its 54 banking centers with 37 banking centers in the Houston metropolitan statistical area (“MSA”), 16 banking centers in the Beaumont MSA and one banking center in Dallas, Texas. Merger of Equals— The merger of equals (the “Merger”) between Allegiance Bancshares, Inc. (“Allegiance”) and CBTX, Inc. (“CBTX”), was effective on October 1, 2022, with CBTX as the surviving corporation that was renamed Stellar Bancorp, Inc. At the effective time of the Merger, each outstanding share of Allegiance common stock was converted into the right to receive 1.4184 shares of common stock of the Company. Immediately following the Merger, CommunityBank of Texas, N.A. (“CommunityBank”), a national banking association and a wholly-owned subsidiary of CBTX, merged with and into Allegiance Bank, a wholly owned subsidiary of Allegiance, with Allegiance Bank as the surviving bank. Allegiance Bank changed its name to Stellar Bank on February 18, 2023 in connection with the operational conversion. The Merger constituted a business combination and was accounted for as a reverse merger using the acquisition method of accounting. As a result, Allegiance was the accounting acquirer and CBTX was the legal acquirer and the accounting acquiree. Accordingly, the historical financial statements of Allegiance became the historical financial statements of the combined company for all periods prior to October 1, 2022 (the “Merger Date”). In addition, the assets and liabilities of CBTX were recorded at their estimated fair values and added to those of Allegiance as of October 1, 2022. The determination of fair value required management to make estimates about discount rates, expected future cash flows, market conditions and other future events that are subjective. The Company’s results of operations for the year ended December 31, 2022 reflect Allegiance’s results for the first nine months of 2022 and the results for Stellar for the fourth quarter of 2022, after the Merger on October 1, 2022. The Merger had a significant impact on all aspects of the Company’s financial statements and, as a result, financial results for periods after the Merger are not comparable to financial results for periods prior to the Merger. See Note 2 – Acquisitions in the accompanying notes to the consolidated financial statements for the impact of the Merger. Use of Estimates— The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the reporting of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash and cash equivalents —Cash and cash equivalents include cash, deposits with other financial institutions with maturities not greater than one year. Net cash flows are reported for customer loan and deposit transactions. The Bank can be required by the Federal Reserve Bank of Dallas to maintain average reserve balances. The Bank was not required to maintain reserve balances at December 31, 2024 and 2023. Securities —Debt securities are classified as available for sale when they might be sold before maturity. Securities available for sale are carried at fair value. Unrealized gains and losses are excluded from earnings and reported, net of tax, as a separate component of shareholders’ equity until realized. Securities within the available for sale portfolio may be used as part of the Company’s asset/liability strategy and may be sold in response to changes in interest rate risk, prepayment risk or other similar economic factors. Interest earned on these assets is included in interest income. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield method, except for mortgage backed securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. Loans —Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost net of the allowance for credit losses on loans. Amortized cost is the principal balance outstanding, net of purchase accounting adjustments and deferred fees and costs. Accrued interest receivable on loans totaled $30.4 million at December 31, 2024 and was reported in accrued interest receivable on the consolidated balance sheets. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of origination costs, are deferred and recognized in interest income using the interest method without anticipating prepayments. Interest income on loans is discontinued and placed on nonaccrual status at the time the loan is 90 days delinquent. All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Loans are returned to accrual status when all the principal and interest amount contractually due are brought current and future payments are reasonably assured. Nonrefundable Fees and Costs Associated with Lending Activities —Loan commitment and loan origination fees, and certain direct origination costs, are deferred and recognized in interest income as an adjustment to yield without anticipating prepayments using the interest method over the related loan life or; if the commitment expires unexercised, balances are recognized in income upon expiration of the commitment. Nonperforming and Past Due Loans —The Company has several procedures in place to assist it in maintaining the overall quality of its loan portfolio. The Company has established underwriting guidelines to be followed by its officers, and monitors its delinquency levels for any negative or adverse trends. There can be no assurance, however, that the Company’s loan portfolio will not become subject to increasing pressures from deteriorating borrower credit due to general economic conditions or other factors. Past due status is based on the contractual terms of the loan. Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. The Company generally classifies a loan as nonperforming, automatically places the loan on nonaccrual status, ceases accruing interest and reverses all unpaid accrued interest against interest income, when, in management’s opinion, the borrower may be unable to meet payment obligations, when the payment of principal or interest on a loan is delinquent for 90 days, as well as when required by regulatory provisions, unless the loan is in the process of collection and the underlying collateral fully supports the carrying value of the loan. Any payments received on nonaccrual loans are applied first to outstanding principal amounts. Interest income is subsequently recognized only to the extent cash payments are received in excess of principal due. Any excess is treated as recovery of lost interest. Loans are returned to accrual status when all of the principal and interest amounts contractually due are brought current and future payments are reasonably assured. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. If the decision is made to continue accruing interest on the loan, periodic reviews are made to confirm the accruing status of the loan. Nonaccrual loans and loans past due 90 days include both smaller balance homogeneous loans that are collectively and individually evaluated. When available information confirms that specific loans, or portions thereof, are uncollectible, these amounts are charged-off against the allowance. All loan types are considered delinquent after 30 days past due and are typically charged-off or charged-down no later than 120 days past due, with consideration of, but not limited to, the following criteria in determining the need and timing of the charge-off or charge-down: (1) the Bank is in the process of repossession or foreclosure and there appears to be a likely deficiency, (2) the collateral securing the loan has been sold and there is an actual deficiency, (3) the Bank is proceeding with lengthy legal action to collect its balance, (4) the borrower is unable to be located or (5) the borrower has filed bankruptcy. Charge-offs occur when the Company confirms a loss on a loan. A llowance for Credit Losses— The allowance for credit losses is a valuation account that is established through a provision for (or reversal of) credit losses charged to expense, which represents management’s best estimate of lifetime expected losses based on reasonable and supportable forecasts, historical loss experience, and other qualitative considerations. The allowance for credit losses includes the allowance for credit losses on loans, which is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on loans, and the allowance for credit losses on unfunded commitments reported in other liabilities. Allowance for Credit Losses on Loans — The level of the allowance is based upon management’s evaluation of historical default and loss experience, current and projected economic conditions, asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect the borrowers' ability to repay a loan (including the timing of future payments), the estimated value of any underlying collateral, composition of the loan portfolio, industry and peer bank loan quality indications and other pertinent factors, including regulatory recommendations. The allowance for credit losses on loans maintained by management is believed adequate to absorb all expected future losses in the loan portfolio at the balance sheet date. The Company disaggregates the loan portfolio into pools for purposes of determining the allowance for credit losses. These pools are based on the level at which the Company develops, documents and applies a systematic methodology to determine the allowance for credit losses. Loans with similar risk characteristics are collectively evaluated resulting in loss estimates as determined by applying reserve factors, such as historical lifetime loan loss experience, concentration risk of specific loan types, the volume, growth and composition of the Company’s loan portfolio, current economic conditions and reasonable and supportable forecasted economic conditions that may affect the borrower’s ability to pay and the value of collateral, the evaluation of the Company’s loan portfolio through its internal loan review process, general economic conditions and other qualitative risk factors both internal and external to the Company and other relevant factors, designed to estimate current expected credit losses, to amortized cost balances over the remaining contractual life of the collectively evaluated portfolio. Loans with similar risk characteristics are aggregated into homogeneous pools for assessment. Historical lifetime loan loss experience is determined by utilizing an open-pool (“cumulative loss rate”) methodology. Adjustments to the historical lifetime loan loss experience are made for differences in current loan pool risk characteristics such as portfolio concentrations, delinquency, nonaccrual, and watch list levels, as well as changes in current and forecasted economic conditions such as unemployment rates, property and collateral values, and other indices relating to economic activity. Losses are predicted over a period of time determined to be reasonable and supportable, and at the end of the reasonable and supportable period losses are reverted to long term historical averages. The reasonable and supportable period and reversion period are re-evaluated each year by the Company and are dependent on the current economic environment among other factors. A reasonable and supportable period of twelve months was utilized for all loan pools, followed by an immediate reversion to long term averages. Based on a review of these factors for each loan type, the Company applies an estimated percentage to the outstanding balance of each loan type. Loans that no longer share risk characteristics with the collectively evaluated loan pools are evaluated on an individual basis and are excluded from the collectively evaluated pools. In order to assess which loans are to be individually evaluated, the Company follows a loan review program to evaluate the credit risk in the total loan portfolio and assigns risk grades to each loan. Individual credit loss estimates are typically performed for nonaccrual loans, modified loans and all other loans identified by management. All loans deemed as being individually evaluated are reviewed on a quarterly basis in order to determine whether a specific loan loss reserve is required. The Company considers certain loans to be collateral dependent if the borrower is experiencing financial difficulty and management expects repayment for the loan to be substantially through the operation or sale of the collateral. For collateral dependent loans, loss estimates are based on the fair value of collateral, less estimated costs to sell and outstanding property taxes (if applicable). Collateral values supporting individually evaluated loans are assessed quarterly and appraisals are typically obtained at least annually. Regarding collateral dependent loans, the Company allocates a specific loan loss reserve on an individual loan basis primarily based on the value of the collateral securing the individually evaluated loan. Through this loan review process, the Company assesses the overall quality of the loan portfolio and the adequacy of the allowance for credit losses on loans while considering risk elements attributable to particular loan types in assessing the quality of individual loans. In addition, for each category of loans, the Company considers secondary sources of income and the financial strength and credit history of the borrower and any guarantors. A change in the allowance for credit losses on loans can be attributable to several factors, most notably specific reserves for individually evaluated loans, historical lifetime loan loss information, and changes in economic factors and growth in the loan portfolio. Specific reserves that are calculated on an individual basis and the qualitative assessment of all other loans reflect current changes in the credit quality of the loan portfolio. Historical lifetime credit losses, on the other hand, are based on an open-pool (“cumulative loss rate”) methodology, which is then applied to estimate lifetime credit losses in the loan portfolio. The allowance for credit losses on loans is further determined by the size of the loan portfolio subject to the allowance methodology and factors that include Company-specific risk indicators and general economic conditions, both of which are constantly changing. The Company evaluates the economic and portfolio-specific factors on a quarterly basis to determine a qualitative component of the general valuation allowance. These factors include current economic metrics, reasonable and supportable forecasted economic metrics, delinquency trends, credit concentrations, nature and volume of the portfolio and other adjustments for items not covered by specific reserves and historical lifetime loss experience. Based on the Company’s actual historical lifetime loan loss experience relative to economic and loan portfolio-specific factors at the time the losses occurred, management is able to identify the probable level of lifetime losses as of the date of measurement. The Company’s analysis of qualitative, or economic, factors on pools of loans with common risk characteristics, in combination with the quantitative historical lifetime loss information and specific reserves, provides the Company with an estimate of lifetime losses. The calculation of current expected credit losses is inherently subjective, as it requires management to exercise judgment in determining appropriate factors used to determine the allowance. The estimated loan losses for all loan pools are adjusted for changes in qualitative factors not inherently considered in the quantitative analyses to bring the allowance to the level management believes is appropriate based on factors that have not otherwise been fully accounted for, including adjustments for foresight risk, input imprecision and model imprecision. The qualitative categories and the measurements used to quantify the risks within each of these categories are subjectively selected by management, but measured by objective measurements period over period. The data for each measurement may be obtained from internal or external sources. The current period measurements are evaluated and assigned a factor commensurate with the current level of risk relative to past measurements over time. The resulting qualitative adjustments are applied to the relevant collectively evaluated loan portfolios. These adjustments are based upon quarterly trend assessments in portfolio concentrations, changes in lending policies and procedures, policy exceptions, independent loan review results, internal risk ratings and peer group credit quality trends. The qualitative allowance allocation, as determined by the processes noted above, is increased or decreased for each loan pool based on the assessment of these various qualitative factors. The determination of the appropriate qualitative adjustment is based on management's analysis of current and expected economic conditions and their impact to the portfolio, as well as internal credit risk movements and a qualitative assessment of the lending environment, including underwriting standards. Management recognizes the sensitivity of various assumptions made in the quantitative modeling of expected losses and may adjust reserves depending upon the level of uncertainty that currently exists in one or more assumptions. While policies and procedures used to estimate the allowance for credit losses on loans, as well as the resultant provision for credit losses charged to income, are considered adequate by management and are reviewed periodically by regulators and internal audit, they are approximate and could materially change based on changes within the loan portfolio and effects from economic factors. There are factors beyond the Company’s control, such as changes in projected economic conditions, including political instability or global events affecting the U.S. economy, real estate markets or particular industry conditions which could cause changes to expectations for current conditions and economic forecasts that could result in an unanticipated increase in the allowance and may materially impact asset quality and the adequacy of the allowance for credit losses and thus the resulting provision for credit losses. In assessing the adequacy of the allowance for credit losses on loans, the Company considers the results of its ongoing independent loan review process. The Company undertakes this process both to ascertain those loans in the portfolio with elevated credit risk and to assist in its overall evaluation of the risk characteristics of the entire loan portfolio. Its loan review process includes the judgment of management, independent internal loan reviewers and reviews that may have been conducted by third-party reviewers including regulatory examiners. The Company incorporates relevant loan review results in the allowance. Losses are estimated over the remaining contractual terms of loans, adjusted for prepayments. The contractual term excludes expected extensions, renewals and modifications unless management has a reasonable expectation at the reporting date that a troubled loan modification will be executed or such renewals, extensions or modifications are included in the original loan agreement and are not unconditionally cancellable by the Company. Credit losses are estimated on the amortized cost basis of loans, which includes the principal balance outstanding, purchase discounts and premiums and deferred loan fees and costs. Loan losses are not estimated for accrued interest receivable as interest that is deemed uncollectible is written off through interest income in a timely manner. Accrued interest is presented separately on the balance sheets and, as allowed under Accounting Standards Codification (“ASC”) Topic 326 - Measurement of Credit Losses on Financial Instruments (“ASC Topic 326”), is excluded from the tabular loan disclosures in Note 5 – Loans and Allowance for Credit Losses. Allowance for Credit Losses on Unfunded Commitments — The Company estimates expected credit losses over the contractual term in which the Company is exposed to credit risk through a contractual obligation to extend credit, unless the obligation is unconditionally cancellable by the Company. The allowance for credit losses on unfunded commitments is recorded on the balance sheet in other liabilities and is adjusted as a provision for (or reversal of) credit loss expense. The estimates are determined based on the likelihood of funding during the contractual term and an estimate of credit losses subsequent to funding. Estimated credit losses on subsequently funded balances are based on the same assumptions as used to estimate credit losses on existing funded loans. Allowance for Credit Losses - Securities Available for Sale — For securities classified as available for sale that are in an unrealized loss position at the balance sheet date, the Company first assesses whether or not it intends to sell the security, or more likely than not will be required to sell the security, before recovery of its amortized cost basis. If either criteria is met, the security’s amortized cost basis is written down to fair value through net income. If neither criteria is met, the Company evaluates whether any portion of the decline in fair value is the result of credit deterioration. Such evaluations consider the extent to which the amortized cost of the security exceeds its fair value, changes in credit ratings and any other known adverse conditions related to the specific security. If the evaluation indicates that a credit loss exists, an allowance for credit losses is recorded through provisions for credit losses for the amount by which the amortized cost basis of the security exceeds the present value of cash flows expected to be collected, limited by the amount by which the amortized cost exceeds fair value. Losses are charged against the allowance when management believes the uncollectibility of an available for sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Any impairment not recognized in the allowance for credit losses is recognized in other comprehensive income. For certain types of debt securities, such as U.S. Treasuries and other securities with government guarantees, entities may expect zero credit losses. Accrued interest receivable on securities available for sale totaled $7.2 million at December 31, 2024 and is excluded from the estimate of credit losses Loans acquired in a business combination — The Company records purchased credit deteriorated (“PCD”) loans, defined as a more-than-insignificant deterioration in credit quality since origination or issuance, at the purchase price plus the allowance for credit losses expected at the time of acquisition. Under this method, there is no credit loss expense affecting net income on acquisition of PCD loans. Changes in estimates of expected losses after acquisition are recognized as credit loss expense (or reversal of credit loss expense) in subsequent periods. Any noncredit discount or premium resulting from the acquisition of purchased loans with credit deterioration was allocated to each individual loan. The determination of PCD classification on acquired loans can have a significant impact on the accounting for these loans. At acquisition date, the initial allowance for PCD loans that do not share risk characteristics with pooled PCD loans, are evaluated by the Company on an individual loan basis. The expected credit loss was measured based on net realizable value, that is, the difference between the discounted value of the expected future cash flows, based on the original effective interest rate, and the amortized cost basis of the loan. For these loans, the Company recognizes expected credit loss equal to the amount by which the net realizable value of the loan is less than the amortized cost basis of the loan (which is net of previous charge-offs), except when the loan is collateral dependent, that is, when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. In these cases, expected credit loss was measured as the difference between the amortized cost basis of the loan and the fair value of the collateral. The fair value of the collateral is adjusted for the estimated costs to sell the loan if repayment or satisfaction of a loan is dependent on the sale (rather than only on the operation) of the collateral. The noncredit discount or premium, after the adjustment for the allowance for credit losses, shall be accreted to interest income using the interest method based on the effective interest rate determined after the adjustment for credit losses at the adoption date. Individually evaluated PCD loans were $12.4 million and the associated allowance for credit losses was $433 thousand at December 31, 2024. A purchased financial asset that does not qualify as a PCD asset is accounted for similar to an originated financial asset. Generally, this means that an entity recognizes the allowance for credit losses for non-PCD assets through net income at the time of acquisition. In addition, both the credit discount and noncredit discount or premium resulting from acquiring a pool of purchased financial assets that do not qualify as PCD assets shall be allocated to each individual asset. This combined discount or premium shall be accreted to interest income using the effective yield method. The fair value of acquired loans involved third-party estimates utilizing input assumptions by management which may be complex or uncertain. The determination of the fair value of acquired loans is based on a discounted cash flow methodology that considers factors such as type of loan and related collateral, and requires management’s judgement on estimates about discount rates, expected future cash flows, market conditions and other future events. For PCD loans, an estimate of expected credit losses was made and added to the purchase price to establish the initial amortized cost basis of the PCD loans. Any difference between the unpaid principal balance and the amortized cost basis is considered to relate to noncredit factors and results in a discount or premium. Discounts and premiums are recognized through interest income on an effective yield method over the life of the loans. For acquired loans not deemed PCD at acquisition, the differences between the initial fair value and the unpaid principal balance are recognized as interest income on an effective-yield basis over the lives of the related loans. For further discussion of our loan accounting and acquisitions, see Note 2 – Acquisitions and Note 5 – Loans and Allowance for Credit Losses. Collateral Dependent Loans with Specific Allocation of Allowance for Credit Losses on Loans —A loan is considered to be a collateral dependent loan when, based on current information and events, the Company expects repayment of the financial assets to be provided substantially through the operation or sale of the collateral and the Company has determined that the borrower is experiencing financial difficulty as of the measurement date. The allowance for credit losses on loans is measured by estimating the fair value of the loan based on the present value of expected cash flows, the market price of the loan, or the underlying fair value of the loan’s collateral. For real estate loans, fair value of the loan’s collateral is generally determined by third-party appraisals or internal evaluations, which are then adjusted for the estimated selling and closing costs related to liquidation of the collateral. For this asset class, the actual valuation methods (income, sales comparable, or cost) vary based on the status of the project or property. For example, land is generally based on the sales comparable method while construction is based on the income and/or sales comparable methods. The unobservable inputs may vary depending on the individual assets with no one of the three methods being the predominant approach. The Company reviews the third-party appraisal for appropriateness and adjusts the value downward to consider selling and closing costs, which typically range from 5% to 10% of the appraised value. For non-real estate loans, fair value of the loan’s collateral may be determined using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business. Loan Modifications — Under Subtopic 310-20, a modification is treated as a new loan only if the following two conditions are met: (1) the terms of the new loan are at least as favorable to the lender as the terms for comparable loans to other customers with similar collection risks; and (2) modifications to the terms of the original loan are more than minor. If either condition is not met, the modification is accounted for as the continuation of the old loan with any effect of the modification treated as a prospective adjustment to the loan’s effective interest rate. Premises and Equipment —Premises and equipment is carried at cost less accumulated depreciation. Depreciation expense is calculated principally using the straight-line method over the estimated useful lives of the assets which range fro m 3 to 39 years. Leasehold improvements are amortized using the straight-line method over the periods of the leases or the estimated useful lives, whichever is shorter. Land is carried at cost. Leases —The Company leases certain branch locations, office facilities and equipment under operating leases. Leases with an initial term of 12 months or less are considered short-term and are not recorded on the balance sheet and the related lease expense is recognized on a straight-line basis over the lease term. For operating leases other than those considered to be short-term, the Company recognizes lease right-of-use assets and related lease liabilities. Such amounts are reported as components of premises and equipment and other liabilities, respectively, on the consolidated balance sheet. The Company owns certain office facilities which it leases to outside parties under operating lessor leases; however, such leases are not significant. Lease payments over the expected term are discounted using the Company’s incremental borrowing rate for borrowings of similar terms. Generally, the Company cannot be reasonably certain about whether or not it will renew a lease until such time as the lease is within the last two years of the existing lease term. When the Company is reasonably certain that a renewal option will be exercised, it measures/remeasure

ACQUISITIONS	ACQUISITIONS Merger of Equals As described in Note 1 – Nature of Operations and Summary of Significant Accounting and Reporting Policies the Merger was completed on October 1, 2022. Allegiance merged with and into CBTX with the surviving corporation renamed Stellar Bancorp, Inc. At the effective date of the Merger, each outstanding share of Allegiance common stock was converted into the right to receive 1.4184 shares of common stock of the Company. The Company issued 28.1 million shares of its common stock to Allegiance shareholders in connection with the Merger, which represented 54.0% of the voting interests in the Company upon completion of the Merger. In accordance with FASB ASC 805-40-30-2, the purchase price in a reverse acquisition is determined based on the number of equity interests the legal acquiree would have had to issue to give the owners of the legal acquirer the same percentage equity interest in the combined entity that results from the reverse acquisition. The Merger was accounted for as a reverse merger using the acquisition method of accounting, which means that for accounting and financial reporting purposes, Allegiance was deemed to have acquired CBTX in the Merger, even though CBTX was the legal acquirer. Accordingly, Allegiance's historical financial statements are the historical financial statements of the combined company for all periods prior to October 1, 2022.

During the measurement period, the Company may record subsequent adjustments to goodwill for provisional amounts recorded at the acquisition date. During the third quarter of 2023, the Company completed the final tax returns related to CBTX's business and operations through September 30, 2022. After completion of these tax returns, the Company increased income tax balances and goodwill in the amount of $58 thousand which finalized all purchase accounting adjustments for the Merger. Goodwill is subject to impairment testing, which must be conducted at least annually or upon the occurrence of a triggering event. Various factors, such as the Company’s results of operations, the trading price of the Company’s common stock relative to the book value per share, macroeconomic conditions and conditions in the banking sector, inform whether a triggering event for an interim goodwill impairment test has occurred. Goodwill is recorded and evaluated for impairment at its reporting unit, the Company. Testing of goodwill impairment comprises a two-step process. First, the Company performs a qualitative assessment to evaluate relevant events or circumstances to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines that it is more likely than not that an impairment has occurred, it proceeds to the quantitative impairment test, whereby it calculates the fair value of the reporting unit and compares it with its carrying amount, including goodwill. In its performance of impairment testing, the Company has the unconditional option to proceed directly to the quantitative impairment test, bypassing the qualitative assessment. If the carrying amount of the reporting unit exceeds the fair value, the amount by which the carrying amount exceeds fair value, up to the carrying value of goodwill, is recorded through earnings as an impairment charge. If the results of the qualitative assessment indicate that it is not more likely than not that an impairment has occurred, or if the quantitative impairment test results in a fair value of the reporting unit that is greater than the carrying amount, then no impairment charge is recorded. The Company's policy is to test goodwill for impairment annually as of October 1st, or on an interim basis if an event triggering an impairment assessment is determined to have occurred. The Company performed its annual impairment test and determined no impairment was necessary for the years ended December 31, 2024, 2023 and 2022.

This belief 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. 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 Company maintains an independent loan review department that reviews and validates the credit risk program on a periodic basis. In addition, an independent third party loan review is performed on a quarterly basis. In connection with the reviews of the loan portfolio, the Company considers risk elements attributable to particular loan types or categories in assessing the quality of individual loans. Some of the risk elements include: Commercial and Industrial Loans— The Company makes commercial and industrial loans in its market area that are underwritten on the basis of the borrower’s ability to service the debt from income. The portfolio includes loans to commercial customers for use in financing working capital needs, equipment purchases and expansions. The loans in this category are repaid primarily from the cash flow of a borrower’s principal business operation. Credit risk in these loans is driven by creditworthiness of a borrower and the economic conditions that impact the cash flow stability from business operations. The Company generally takes as collateral a lien on any available real estate, equipment or other assets owned by the borrower and typically obtains a personal guaranty of the borrower or principal. Commercial Real Estate— The Company makes loans collateralized by owner-occupied, nonowner-occupied and multi-family real estate to finance the purchase or ownership of real estate. The Company’s nonowner-occupied and multi-family commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally dependent on sufficient income from the properties securing the loans to cover operating expenses and debt service. The Company generally requires the borrower to have had an existing relationship with the Company and have a proven record of success. In addition, these loans are generally guaranteed by individual owners of the borrower and have typically lower loan to value ratios. Loans secured by owner-occupied properties represented 47.4% of the outstanding principal balance of the Company’s commercial real estate loans at December 31, 2024. The Company is dependent on the cash flows of the business occupying the property and its owners and requires these loans generally to be secured by property with adequate margins and guaranteed by the individual owners. The Company’s owner-occupied commercial real estate loans collateralized by first liens on real estate typically have fixed interest rates and amortize over a 10 to 20 year period. Commercial real estate loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Credit risk in these loans may be impacted by the creditworthiness of a borrower, property values and the local economies in the Company’s metropolitan area. Construction and Land Development Loans— The Company makes loans to finance the construction of nonresidential and residential properties. Construction loans generally are collateralized by first liens on real estate and generally have floating interest rates. Construction and land development real estate loans are usually based upon estimates of costs and estimated value of the completed project and include independent appraisal reviews and a financial analysis of the developers and property owners. The Company generally conducts periodic inspections, either directly or through an agent, prior to approval of periodic draws on these loans. Underwriting guidelines similar to those described above are also used in the Company’s construction lending activities. The Company may be required to fund additional amounts to complete a project and may have to hold the property for an indeterminate period of time. Sources of repayment of these loans may include permanent loans, sales of developed property or an interim loan commitment from the Company until permanent financing is obtained. These loans are considered to be higher risk than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, general economic conditions and the availability of long-term financing. Credit risk in these loans may be impacted by the creditworthiness of a borrower, property values and the local economies in the Company’s metropolitan area. 1-4 Residential Real Estate Loans— The Company’s lending activities also include the origination of 1-4 family residential mortgage loans (including home equity loans) collateralized by owner-occupied residential properties located in the Company’s market areas. The Company offers a variety of mortgage loan portfolio products which have a term of 5 to 7 years and generally amortize over 10 to 30 years. Loans collateralized by 1-4 family residential real estate generally have been originated in amounts of no more th an 90% o f appraised value. Repayment of these loans is primarily dependent on the personal income and credit rating of the borrowers. Credit risk in these loans can be impacted by economic conditions within the Company’s metropolitan area that might impact either property values or a borrower’s personal income. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over a larger number of borrowers. Consumer and Other Loans— The Company makes a variety of loans to individuals for personal and household purposes including secured and unsecured installment and term loans. Consumer loans are underwritten based on the individual borrower’s income, current debt level, past credit history and the value of any available collateral. Repayment for these loans will come from a borrower’s income source that are typically independent of the loan purpose. The terms of these loans typically range from 12 to 60 months and vary based upon the nature of collateral and size of loan. Credit risk is driven by consumer economic factors, such as, unemployment and general economic conditions in the Company metropolitan area and the creditworthiness of a borrower. In addition, for each category, the Company considers secondary sources of income and the financial strength and credit history of the borrower and any guarantors. Concentrations of Credit A majority of the Company’s lending activity occurs in and around our market. The Company’s loans are primarily loans secured by real estate, including commercial and residential construction, owner-occupied and nonowner-occupied and multi-family commercial real estate, raw land and other real estate based loans.

Credit Quality Indicators The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt. The Company utilizes a risk rating matrix to assign a risk rating to each of its loans. Risk ratings are updated on an ongoing basis and are subject to change by continuous loan monitoring processes including lending management monitoring, executive management and board committee oversight, and independent credit review. As part of the ongoing monitoring of the credit quality of the Company’s loan portfolio and methodology for calculating the allowance for credit losses, management assigns and tracks certain risk ratings to be used as credit quality indicators including trends related to (1) the weighted-average risk grade of loans, (2) the level of classified loans, (3) the delinquency status of loans, (4) nonperforming loans and (5) the general economic conditions in our market. Individual bankers, under the oversight of credit administration, review updated financial information for pass grade commercial loans to reassess the risk grade on an annual basis. When a loan reaches a set of internally designated criteria, including Substandard or higher, a special assets officer will be involved in the monitoring of the loan on an on-going basis. The following is a general description of the risk ratings used by the Company: Pass —Credits in this category contain an acceptable amount of risk. Special Mention —Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Substandard —Loans classified as substandard have well-defined weaknesses on a continuing basis and are inadequately protected by the current net worth and paying capacity of the borrower, declining collateral values, or a continuing downturn in their industry which is reducing their profits to below zero and having a significantly negative impact on their cash flow. These loans so classified are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful —Loans classified as doubtful have all the weaknesses inherent in those classified as substandard 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. Loss —Loans classified as loss are to be charged-off or charged-down when payment is acknowledged to be uncertain or when the timing or value of payments cannot be determined. “Loss” is not intended to imply that the loan or some portion of it will never be paid, nor does it in any way imply that there has been a forgiveness of debt. The following table presents risk ratings by category and the gross charge-offs by primary loan type and year of origination or renewal. Generally, current period renewals of credit are re-underwritten at the point of renewal and considered current period originations for purposes of the table below. The following summarizes the amortized cost basis of loans by year of origination/renewal and credit quality indicator by class of loan as of December 31, 2024 and 2023: December 31, 2024 December 31,

for unfunded commitments on acquired non-PCD loans related to accounting of acquired loans from the Merger. Allowance for Credit Losses on Unfunded Commitments In addition to the allowance for credit losses on loans, the Company has established an allowance for credit losses on unfunded commitments, which is classified in other liabilities and adjusted as a provision for credit loss expense. The allowance represents estimates of expected credit losses over the contractual period in which there is exposure to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on the commitments expected to fund. The estimate of commitments expected to fund is informed by historical analysis looking at utilization rates. The expected credit loss rates applied to the commitments expected to fund is informed by the general valuation allowance utilized for outstanding balances with the same underlying assumptions and drivers. The allowance for credit losses on unfunded commitments as of December 31, 2024 and 2023 was $12.4 million and $11.3 million, respectively. This reserve is maintained at a level management believes to be sufficient to absorb any losses arising from unfunded loan commitments. The Company recorded a provision of $1.1 million for the year ended December 31, 2024 and a reversal of provision of $682 thousand for the year ended December 31, 2023 and a provision of $6.7 million for the year ended December 31, 2022 on unfunded commitments. Collateral Dependent Loans Collateral dependent loans are secured by real estate assets, accounts receivable, inventory and equipment. For a collateral dependent loan, the Company’s evaluation process includes a valuation by appraisal or other collateral analysis adjusted for selling costs, when appropriate. This valuation is compared to the remaining outstanding principal balance of the loan and any loss is included in the allowance for credit losses on loans as a specific allocation.

FAIR VALUE

Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE The Company uses fair value measurements to record fair value adjustments to certain assets and to determine fair value disclosures. Fair value represents the estimated exchange price that would be received from selling an asset or paid to transfer a liability, otherwise known as an “exit price” in the principal or most advantageous market available to the entity in an orderly transaction between market participants on the measurement date. Fair Value Hierarchy Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company groups financial assets and financial liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are: • Level 1—Quoted prices for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. • Level 2—Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3—Significant unobservable inputs that reflect management’s judgment and assumptions that market participants would use in pricing an asset or liability that are supported by little or no market activity. The carrying amounts and estimated fair values of financial instruments that are reported at cost on the balance sheet were as follows: December 31, 2024 Carrying Estimated Fair Value Level 1 Level 2 Level 3 Total (In thousands) Financial assets: Cash and cash equivalents $ 911,216 $ 911,216 $ — $ — $ 911,216 Available for sale securities 1,673,016 — 1,673,016 — 1,673,016 Loans held for investment, net of allowance 7,358,796 — — 7,223,895 7,223,895 Accrued interest receivable 37,884 330 7,197 30,357 37,884 Financial liabilities: Deposits $ 9,128,384 $ — 9,128,234 $ — $ 9,128,234 Accrued interest payable 17,052 — 17,052 — 17,052 Borrowed funds — — — — — Subordinated debt 70,105 — 68,963 — 68,963 December 31, 2023 Carrying Estimated Fair Value Level 1 Level 2 Level 3 Total (In thousands) Financial assets: Cash and cash equivalents $ 399,237 $ 399,237 $ — $ — $ 399,237 Available for sale securities 1,395,680 — 1,395,680 — 1,395,680 Loans held for investment, net of allowance 7,833,449 — — 7,627,962 7,627,962 Accrued interest receivable 44,244 118 6,716 37,410 44,244 Financial liabilities: Deposits $ 8,873,467 $ — $ 8,866,645 $ — $ 8,866,645 Accrued interest payable 11,288 — 11,288 — 11,288 Borrowed funds 50,000 — 50,000 — 50,000 Subordinated debt 109,765 — 109,390 — 109,390 The fair value estimates presented herein are based on pertinent information available to management as of the dates indicated. The following is a description of valuation methodologies used for assets and liabilities recorded at fair value, non-financial assets and non-financial liabilities and for estimating fair value for financial instruments not recorded at fair value: Cash and Cash Equivalents —The carrying amount is a reasonable estimate of fair value for these short-term instruments. The Company classifies the estimated fair value of these instruments as Level 1. Available for Sale Securities —Fair values for available for sale securities are based upon quoted market prices, if available, and are considered Level 1 inputs. For all other available for sale securities, if quoted prices are not available, fair values are measured based on market prices for similar securities and are considered Level 2 inputs. For these securities, the Company generally 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 prepayment speeds, credit information and the bond’s terms and conditions, among other things. For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators and are considered Level 3 inputs. Available for sale securities are recorded at fair value on a recurring basis. Loans —The estimated fair value approximates carrying value for variable-rate loans that reprice frequently and that have no significant change in credit risk resulting in a Level 3 classification. Fair values for fixed-rate loans and variable rate loans which reprice infrequently are estimated by discounting future cash flows. In accordance with ASU 2016-01, the discount rates used to determine the fair value of loans used interest rate spreads that reflect factors such as liquidity, credit and nonperformance risk of the loans. Deposits —The fair value of demand deposits (e.g., interest and noninterest checking, savings and certain types of money market deposits) is the amount payable on demand at the reporting date (i.e., their carrying amount) resulting in a Level 2 classification. The fair value of fixed rate certificates of deposit is estimated using a discounted cash flows calculation that applies interest rates currently offered on certificates of deposit to a schedule of aggregated expected monthly maturities on time deposits resulting in a Level 2 classification. Accrued Interest —The carrying amounts of accrued interest approximate their fair values resulting in a Level 1, 2 or 3 classification. Borrowed Funds —The fair value of the Company’s borrowed funds is estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements and are measured utilizing Level 2 inputs. Subordinated Debt —The fair values of subordinated debentures and notes are estimated using discounted cash flow analyses based on the Company’s current borrowing rates for similar types of borrowing arrangements and are measured utilizing Level 2 inputs. Interest Rate Swaps and Credit Risk Participation Agreements —Fair value measurements for interest rate swaps are obtained from an independent pricing service which uses the income approach. The income approach calls for the utilization of valuation techniques to convert future cash flows as due to be exchanged per the terms of the financial instrument, into a single present value amount. Measurement is based on the value indicated by the market expectations about those future amounts as of the measurement date. The proprietary curves of the independent pricing service utilize pricing models derived from industry standard analytic tools, considering both Level 1 and Level 2 inputs. Interest rate swaps are classified as Level 2. Interest rate swaps are recorded at fair value on a recurring basis. Off-balance sheet instruments —The fair values of off-balance sheet commitments to extend credit and standby letters of credit financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. The Company has reviewed the unfunded portion of commitments to extend credit as well as standby and other letters of credit and has determined that the fair value of such financial instruments is not material.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTS The Company has outstanding interest rate swap contracts with certain customers and equal and offsetting interest rate swaps with other financial institutions entered into at the same time. These interest rate swap contracts are not designated as hedging instruments for mitigating interest rate risk. The objective of the transactions is to allow customers to effectively convert a variable rate loan to a fixed rate. In connection with each swap transaction, the Company agreed to pay interest to the customer 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 agreed to pay a third-party 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 do 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 December 31, 2024 and 2023, management determined there was no such deterioration. At December 31, 2024 and 2023, the Company had nine and 15 interest rate swap agreements outstanding with borrowers and financial institutions, respectively. Changes in the net fair value are recognized in other noninterest income. Fair value amounts are included in other assets and other liabilities. At December 31, 2024 and 2023, the Company had three credit risk participation agreements with another financial institution that are associated with interest rate swaps related to loans for which the Company is the lead agent bank and the other financial institution provides credit protection to the Company should the borrower fail to perform under the terms of the interest rate swap agreements. The fair value of the agreements is determined based on the market value of the underlying interest rate swaps adjusted for credit spreads and recovery rates.

SUBORDINATED DEBT	SUBORDINATED DEBT Junior Subordinated Debentures In connection with the acquisition of F&M Bancshares, Inc. in 2015, Stellar assumed Farmers & Merchants Capital Trust II and Farmers & Merchants Capital Trust III. Each of the trusts is a capital or statutory business trust organized for the sole purpose of issuing trust securities and investing the proceeds in Stellar’s junior subordinated debentures. The preferred trust securities of each trust represent preferred beneficial interests in the assets of the respective trusts and are subject to mandatory redemption upon payment of the junior subordinated debentures held by the trust. The common securities of each trust are wholly owned by Stellar. Each trust’s ability to pay amounts due on the trust preferred securities is solely dependent upon Stellar making payment on the related junior subordinated debentures. The debentures, which are the only assets of each trust, are subordinate and junior in right of payment to all of Stellar’s present and future senior indebtedness. Stellar has fully and unconditionally guaranteed each trust’s obligations under the trust securities issued by such trust to the extent not paid or made by each trust, provided such trust has funds available for such obligations. The trust preferred securities bear a floating rate of interest equal to 3-Month SOFR plus a spread adjustment. The junior subordinated debentures are included in Tier 1 capital under current regulatory guidelines and interpretations. Under the provisions of each issue of the debentures, the Company has the right to defer payment of interest on the debentures at any time, or from time to time, for periods not exceeding five years. If interest payments on either issue of the debentures are deferred, the distributions on the applicable trust preferred securities and common securities will also be deferred. A summary of pertinent information related to the Company’s junior subordinated debentures outstanding at December 31, 2024 is set forth in the table below: Description Issuance Date Trust Junior Maturity Date (1) (Dollars in thousands) Farmers & Merchants Capital Trust II November 13, 2003 $ 7,500 $ 7,732 November 8, 2033 Farmers & Merchants Capital Trust III June 30, 2005 3,500 3,609 July 7, 2035 $ 11,341 (1) All debentures were callable at December 31, 2024. Subordinated Notes In December 2017, the Bank issued $40.0 million aggregate principal amount of Fixed-to-Floating Rate Subordinated Notes (the “Bank Notes”) due December 15, 2027 and bore a floating rate of interest equal to 3-Month SOFR plus 3.03%. In December 2024, the Bank redeemed the Bank Notes at a redemption price equal to 100% of the principal amount of Bank Notes plus accrued and unpaid interest. In September 2019, Stellar issued $60.0 million aggregate principal amount of Fixed-to-Floating Rate Subordinated Notes (the “Company Notes”) due October 1, 2029. As of December 31, 2024, the Company Notes bore at a floating rate equal to 3-Month SOFR plus 3.13% and a spread adjustment for each quarterly interest period, payable quarterly in arrears on January 1, April 1, July 1 and October 1 of each year.

Share-Based Payment Arrangement [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION Under the 2022 Omnibus Incentive Plan (the “2022 Plan”) the Company is authorized to issue a maximum aggregate of 2,000,000 shares of common stock. All restricted stock and performance share awards outstanding at December 31, 2024 were issued under the 2022 Plan. At December 31, 2024, there were 810,276 shares reserved and available for issuance under the 2022 Plan. The Company accounts for stock-based employee compensation plans using the fair value-based method of accounting. The Company recognized total stock-based compensation expense of $10.8 million, $9.9 million and $9.0 million for the years ended December 31, 2024, 2023 and 2022, respectively. Stock Options Stock options outstanding at December 31, 2024 were issued under equity compensation plans that are no longer active. No additional shares may be issued under these compensation plans. There were no stock options granted during 2024 and 2023. The fair value of stock options granted is estimated at the date of grant using the Black-Scholes model. Options are exercisable up to 10 years from the date of the grant and, dependent on the terms of the applicable award agreement, generally vest 3 to 4 years after the date of grant. Stock option activity for the years ended December 31, 2024 and 2023 was as follows: Number of Weighted Weighted Aggregate (Shares in thousands) (In years) (In thousands) Options outstanding, January 1, 2023 368 $ 17.89 2.72 $ 4,256 Options granted — — Options exercised (70) 14.16 Options forfeited (40) 20.06 Options outstanding, December 31, 2023 258 $ 18.56 2.09 $ 2,398 Options granted — — Options exercised (133) 16.34 Options forfeited (6) 19.89 Options outstanding, December 31, 2024 119 $ 20.98 2.05 $ 876 Options vested and exercisable, December 31, 2024 119 0 $ 20.98 2.05 $ 876 Information related to the stock options exercises for the years indicated below is as follows: 2024 2023 2022 (Dollars in thousands, except per share data) Intrinsic value of options exercised $ 1,118 $ 776 $ 2,112 Cash received from option exercises 2,173 986 2,510 Restricted Stock Awards The fair value of the Company’s restricted stock awards is estimated based on the market value of the Company’s common stock at the date of grant, which is the closing price of the Company’s common stock on the day before the grant date. The shares of restricted stock granted generally vest over a period of two Nonvested shares of restricted stock activity for the years ended December 31, 2024 and 2023 was as follows: Number of Weighted (Shares in thousands) Nonvested share awards outstanding, January 1, 2023 501 $ 32.84 Share awards granted 271 25.54 Share awards vested (232) 31.91 Unvested share awards forfeited or cancelled (82) 30.72 Nonvested share awards outstanding, December 31, 2023 458 $ 29.38 Share awards granted 314 23.20 Share awards vested (279) 30.29 Unvested share awards forfeited or cancelled (64) 25.71 Nonvested share awards outstanding, December 31, 2024 429 $ 24.81 At December 31, 2024, there was $7.2 million of unrecognized compensation expense related to the restricted stock awards, which is expected to be recognized over a weighted-average period of 1.68 years. The total fair value of restricted stock awards that fully vested during the years ended December 31, 2024, 2023 and 2022 was approximately $6.8 million, $5.0 million and $9.1 million, respectively. Performance Share Units and Performance Share Awards The Company’s PSUs and PSAs are earned subject to certain performance goals being met after a specified performance period and are settled in shares of Company common stock. The Company awarded 77,624 PSUs and 127,345 PSAs during the years ended December 31, 2024 and 2023, respectively, under the 2022 Plan. PSUs issued in 2024 are not considered outstanding at the date of issuance as the grantee does not become the record owner of the restricted stock and does not have voting, dividend and other shareholder rights. The grant date fair value of the PSUs and PSAs is based on the probable outcome of the applicable performance conditions and is calculated at target based on a combination of the closing market price of our common stock on the grant date and a Monte Carlo simulated fair value in accordance with ASC 718. At December 31, 2024, there was $2.5 million of unrecognized compensation expense related to the PSUs and PSAs, which is expected to be recognized over a weighted-average period of 1.72 years.

Commitments and Contingencies Disclosure [Abstract]
OFF-BALANCE SHEET ARRANGEMENTS, COMMITMENTS AND CONTINGENCIES	OFF-BALANCE SHEET ARRANGEMENTS, COMMITMENTS AND CONTINGENCIES In the normal course of business, the Company enters into various transactions, which, in accordance with accounting principles generally accepted in the United States are not included in the Company’s consolidated balance sheets. The Company enters into these transactions to meet the financing needs of its customers. These transactions include commitments to extend credit and standby and commercial letters of credit, which involve to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The Company uses the same credit policies in making commitments and conditional obligations as it does for on balance sheet instruments. The contractual amounts of financial instruments with off-balance sheet risk were as follows: December 31, 2024 December 31, 2023 Fixed Variable Fixed Variable (In thousands) Commitments to extend credit $ 440,403 $ 1,261,520 $ 367,068 $ 1,425,946 Standby letters of credit 16,818 26,821 16,147 21,514 Total $ 458,662 $ 1,286,899 $ 383,215 $ 1,447,460 At December 31, 2024 and 2023, the Company had FHLB letters of credit in the amount of $2.10 billion and $1.82 billion, respectively, pledged as collateral for public and other deposits of state and local government agencies. For more information on FHLB borrowings, see Note 10 – Borrowings and Borrowing Capacity. C ommitments to Extend Credit 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 are expected to expire without being fully drawn upon, the total commitment amounts disclosed do not necessarily represent future cash funding requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The Company minimizes its exposure to loss under these commitments by subjecting them to credit approval and monitoring procedures. Management assesses the credit risk associated with certain commitments to extend credit in determining the level of the allowance for credit losses. The amount and type of collateral, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the customer. Commitments to make loans are generally made for an approval period of 120 days or less. As of December 31, 2024, the fixed rate loan commitments had interest rates ranging from 2.08% to 13.50% with a weighted average maturity of 1.93 years and weighted average rate of 7.21%. Standby Letters of Credit Standby letters of credit are written conditional commitments issued by the Company to guarantee the performance of a customer to a third party. In the event of nonperformance by the customer, the Company has the rights to the underlying collateral. The credit risk to the Company in issuing letters of credit is substantially similar to that involved in extending loan facilities to its customers. The Company’s policy for obtaining collateral, and the nature of such collateral, is substantially similar to that involved in making commitments to extend credit. Litigation The Company is subject to claims and lawsuits which arise primarily in the ordinary course of business. Based on information presently available and advice received from legal counsel representing the Company, it is the opinion of management that the disposition or ultimate determination of such claims and lawsuits will not have a material adverse effect on the financial position or results of operations of the Company.

REGULATORY CAPITAL MATTERS

Regulatory Capital Matters [Abstract]
REGULATORY CAPITAL MATTERS	REGULATORY CAPITAL MATTERS The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Capital adequacy guidelines, and for banks, prompt corrective action regulations involve quantitative measures of assets, liabilities and certain off balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weightings and other factors. Failure to meet minimum capital requirements can initiate actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Management believes as of December 31, 2024 and 2023, the Company and the Bank met all capital adequacy requirements to which they were subject. Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized, although these terms are not used to represent overall financial condition. If less than well capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited as is asset growth and expansion, and capital restoration plans are required. At year-end 2024 and 2023, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the institution’s category. The Bank’s capital ratios as of December 31, 2024 exceed the minimum levels necessary to be considered “well-capitalized” under the prompt corrective action regulatory framework. The following is a summary of the Company’s and the Bank’s actual and required capital ratios as of December 31, 2024 and 2023: Actual Minimum Required for Capital Minimum Required Plus To Be Categorize d As Well Capitalized Under Prompt Corrective Amount Ratio Amount Ratio Amount Ratio Amount Ratio (Dollars in thousands) STELLAR BANCORP, INC.

Earnings Per Share [Abstract]
EARNINGS PER COMMON SHARE	EARNINGS PER COMMON SHARE Basic earnings per common share is calculated as net income divided by the weighted average number of common shares outstanding during the period. All restricted shares and performance share awards are considered outstanding at the date of grant. Diluted earnings per common share is computed using the weighted-average number of common shares determined for the basic earnings per common share computation plus the potential dilutive effect of outstanding stock options and performance share units using the treasury stock 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 below.

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATIONThe Company’s reportable segment is determined by the Chief Financial Officer, who is the designated chief operating decision maker, based upon information provided about the Company’s services offered, primarily banking operations. The segment is also distinguished by the level of information provided to the chief operating decision maker, who uses such information to evaluate the financial performance of the Company’s business by evaluating consolidated net income, significant expenses and budget to actual results in assessing the Company’s segment and in the determination of allocating resources. The chief operating decision maker uses consolidated net income to benchmark the Company against its competitors. The benchmarking analysis coupled with monitoring of budget to actual results are used in assessment performance and in establishing compensation. The presentation of financial performance to the chief operating decision maker is consistent with amounts and financial statement lines shown on the Company’s consolidated balance sheets and consolidated statements of income. Loans, investments and deposits in other financial institutions provide income in the banking operation. Interest expense, provisions for credit losses and salaries and benefits are the significant expenses in the banking operation. All of the Company’s financial results are similar and considered by management to be aggregated into one reportable operating segment.

Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	As one of the critical elements of the Company’s overall ERM approach, the Company’s cybersecurity risk management program and strategy is focused on the following key areas: • Governance —As discussed in more detail under the heading “Governance,” the Board’s oversight of cybersecurity risk management is supported by the Risk Committee of the Board (the “Risk Committee”) and by the Technology Committee of the Board (the “Technology Committee”), which regularly interacts with the Company’s ERM function, CRO, Chief Information Officer (“CIO”), CISO and other members of management and relevant management committees. In recognition of the evolving landscape of cyber threats and the critical importance of safeguarding our digital assets and customer information, the Bank has taken proactive steps to enhance our cybersecurity framework and risk management practices. Central to these efforts is the expertise and oversight provided by the Board, particularly through the involvement of its Technology Committee. This committee is composed of directors with significant experience in technology and cybersecurity, working to align our cyber risk management strategies with best practices and industry standards. • Technical Safeguards —The Company deploys layered technical safeguards that are designed to protect the Company’s information systems from cybersecurity threats, including firewalls, intrusion prevention and detection systems, anti-malware functionality and access controls, which are evaluated and improved through penetration testing, vulnerability assessments and cybersecurity threat intelligence. • Incident Response and Recovery Planning —The Company has implemented a robust, cross-functional approach to identifying, preventing and mitigating cybersecurity threats and incidents. To that end, the Company has established and maintains a comprehensive cybersecurity incident response plan that establishes a structured approach for the Company’s response to a cybersecurity incident, such plan is tested and evaluated on a regular basis. The Company has implemented controls and procedures that provide for the prompt escalation of certain cybersecurity incidents so that decisions regarding the public disclosure and reporting of such incidents can be made by management in a timely manner. • Outside Experts —The Company routinely works with outside experts, consultants, auditors and other third parties in connection with managing its cybersecurity risks and for advice regarding best practices and technical expertise. • Third-Party Risk Management —The Company maintains a robust, risk-based approach to identifying and overseeing cybersecurity risks presented by third parties, including vendors, service providers and other external users of the Company’s systems, as well as the systems of third parties that could adversely impact our business in the event of a cybersecurity incident affecting those third-party systems. • Education and Awareness —The Company provides regular, mandatory training for personnel regarding cybersecurity threats to equip the Company’s personnel with effective tools to address cybersecurity threats. The Company engages in the periodic assessment and testing of the Company’s policies, standards, processes and practices that are designed to address cybersecurity threats and incidents. These efforts include a wide range of activities, including audits, assessments, tabletop exercises, vulnerability testing and other exercises focused on evaluating the effectiveness of our cybersecurity measures and planning. The Company regularly engages third parties to perform assessments on our cybersecurity measures, including information security maturity assessments, audits and independent reviews of our information security control environment and operating effectiveness. The results of such assessments, audits and reviews are reported to the Audit Committee of the Board, the Risk Committee, the Technology Committee and the Board. The Company adjusts its cybersecurity policies, standards, processes and practices as necessary based on the information provided by these assessments, audits and reviews. During the fiscal year of this Report, the Company has not identified risks from cybersecurity threats, including as a result of prior cybersecurity incidents that individually or in the aggregate have materially affected or are reasonably anticipated to materially affect the organization. Nevertheless, the Company recognizes cybersecurity threats are ongoing and evolving, and we continue to remain vigilant. For more information on the Company's cybersecurity-related risks, see “Item 1A. Risk Factors – Risks Related to Cybersecurity, Third-Parties and Technology.” Any prior incidents enabled us to enhance our operational and cybersecurity risk management practices. The lessons learned have also informed the Company’s approach to conducting tabletop exercises simulating potential cyber threats, allowing the Company to assess and improve its response protocols.
Cybersecurity Risk Management Processes Integrated [Flag]	true
Cybersecurity Risk Management Processes Integrated [Text Block]	Our risk management program is designed to identify, assess, and mitigate risks across various aspects of our Company, including financial, operational, regulatory, reputational, and legal. The Board is actively involved in oversight of the Company’s risk management program, and cybersecurity represents an important component of the Company’s overall approach to enterprise risk management (“ERM”). The Company’s cybersecurity policies, standards, processes and practices are integrated into the Company’s ERM program and are based on recognized frameworks established by the Federal Financial Institutions Examination Council and other industry recognized standards. Our Chief Information Security Officer (“CISO”), who reports directly to the Bank’s Chief Risk Officer (“CRO”), along with key members of his team, regularly collaborates with peer banks, industry groups, and policymakers to discuss cybersecurity trends and issues to identify best practices. The information security program is periodically reviewed by the Bank’s CISO with the goal of addressing changing threats and conditions.

NATURE OF OPERATIONS AND SUMM_2

NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2024
Accounting Policies [Abstract]
Merger of Equals	Merger of Equals— The merger of equals (the “Merger”) between Allegiance Bancshares, Inc. (“Allegiance”) and CBTX, Inc. (“CBTX”), was effective on October 1, 2022, with CBTX as the surviving corporation that was renamed Stellar Bancorp, Inc. At the effective time of the Merger, each outstanding share of Allegiance common stock was converted into the right to receive 1.4184 shares of common stock of the Company. Immediately following the Merger, CommunityBank of Texas, N.A. (“CommunityBank”), a national banking association and a wholly-owned subsidiary of CBTX, merged with and into Allegiance Bank, a wholly owned subsidiary of Allegiance, with Allegiance Bank as the surviving bank. Allegiance Bank changed its name to Stellar Bank on February 18, 2023 in connection with the operational conversion. The Merger constituted a business combination and was accounted for as a reverse merger using the acquisition method of accounting. As a result, Allegiance was the accounting acquirer and CBTX was the legal acquirer and the accounting acquiree. Accordingly, the historical financial statements of Allegiance became the historical financial statements of the combined company for all periods prior to October 1, 2022 (the “Merger Date”). In addition, the assets and liabilities of CBTX were recorded at their estimated fair values and added to those of Allegiance as of October 1, 2022. The determination of fair value required management to make estimates about discount rates, expected future cash flows, market conditions and other future events that are subjective. The Company’s results of operations for the year ended December 31, 2022 reflect Allegiance’s results for the first nine months of 2022 and the results for Stellar for the fourth quarter of 2022, after the Merger on October 1, 2022. The Merger had a significant impact on all aspects of the Company’s financial statements and, as a result, financial results for periods after the Merger are not comparable to financial results for periods prior to the Merger. See Note 2 – Acquisitions in the accompanying notes to the consolidated financial statements for the impact of the Merger.
Use of Estimates	Use of Estimates— The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the reporting of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash and cash equivalents	Cash and cash equivalents —Cash and cash equivalents include cash, deposits with other financial institutions with maturities not greater than one year. Net cash flows are reported for customer loan and deposit transactions. The Bank can be required by the Federal Reserve Bank of Dallas to maintain average reserve balances. The Bank was not required to maintain reserve balances at December 31, 2024 and 2023.
Securities	Securities —Debt securities are classified as available for sale when they might be sold before maturity. Securities available for sale are carried at fair value. Unrealized gains and losses are excluded from earnings and reported, net of tax, as a separate component of shareholders’ equity until realized. Securities within the available for sale portfolio may be used as part of the Company’s asset/liability strategy and may be sold in response to changes in interest rate risk, prepayment risk or other similar economic factors. Interest earned on these assets is included in interest income. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield method, except for mortgage backed securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method.
Loans	Loans —Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost net of the allowance for credit losses on loans. Amortized cost is the principal balance outstanding, net of purchase accounting adjustments and deferred fees and costs. Accrued interest receivable on loans totaled $30.4 million at December 31, 2024 and was reported in accrued interest receivable on the consolidated balance sheets. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of origination costs, are deferred and recognized in interest income using the interest method without anticipating prepayments. Interest income on loans is discontinued and placed on nonaccrual status at the time the loan is 90 days delinquent. All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Loans are returned to accrual status when all the principal and interest amount contractually due are brought current and future payments are reasonably assured. Loan Modifications — Under Subtopic 310-20, a modification is treated as a new loan only if the following two conditions are met: (1) the terms of the new loan are at least as favorable to the lender as the terms for comparable loans to other customers with similar collection risks; and (2) modifications to the terms of the original loan are more than minor. If either condition is not met, the
Nonrefundable Fees and Costs Associated with Lending Activities	Nonrefundable Fees and Costs Associated with Lending Activities —Loan commitment and loan origination fees, and certain direct origination costs, are deferred and recognized in interest income as an adjustment to yield without anticipating prepayments using the interest method over the related loan life or; if the commitment expires unexercised, balances are recognized in income upon expiration of the commitment.
Allowance for Credit Losses	Nonperforming and Past Due Loans —The Company has several procedures in place to assist it in maintaining the overall quality of its loan portfolio. The Company has established underwriting guidelines to be followed by its officers, and monitors its delinquency levels for any negative or adverse trends. There can be no assurance, however, that the Company’s loan portfolio will not become subject to increasing pressures from deteriorating borrower credit due to general economic conditions or other factors. Past due status is based on the contractual terms of the loan. Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. The Company generally classifies a loan as nonperforming, automatically places the loan on nonaccrual status, ceases accruing interest and reverses all unpaid accrued interest against interest income, when, in management’s opinion, the borrower may be unable to meet payment obligations, when the payment of principal or interest on a loan is delinquent for 90 days, as well as when required by regulatory provisions, unless the loan is in the process of collection and the underlying collateral fully supports the carrying value of the loan. Any payments received on nonaccrual loans are applied first to outstanding principal amounts. Interest income is subsequently recognized only to the extent cash payments are received in excess of principal due. Any excess is treated as recovery of lost interest. Loans are returned to accrual status when all of the principal and interest amounts contractually due are brought current and future payments are reasonably assured. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. If the decision is made to continue accruing interest on the loan, periodic reviews are made to confirm the accruing status of the loan. Nonaccrual loans and loans past due 90 days include both smaller balance homogeneous loans that are collectively and individually evaluated. When available information confirms that specific loans, or portions thereof, are uncollectible, these amounts are charged-off against the allowance. All loan types are considered delinquent after 30 days past due and are typically charged-off or charged-down no later than 120 days past due, with consideration of, but not limited to, the following criteria in determining the need and timing of the charge-off or charge-down: (1) the Bank is in the process of repossession or foreclosure and there appears to be a likely deficiency, (2) the collateral securing the loan has been sold and there is an actual deficiency, (3) the Bank is proceeding with lengthy legal action to collect its balance, (4) the borrower is unable to be located or (5) the borrower has filed bankruptcy. Charge-offs occur when the Company confirms a loss on a loan. A llowance for Credit Losses— The allowance for credit losses is a valuation account that is established through a provision for (or reversal of) credit losses charged to expense, which represents management’s best estimate of lifetime expected losses based on reasonable and supportable forecasts, historical loss experience, and other qualitative considerations. The allowance for credit losses includes the allowance for credit losses on loans, which is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on loans, and the allowance for credit losses on unfunded commitments reported in other liabilities. Allowance for Credit Losses on Loans — The level of the allowance is based upon management’s evaluation of historical default and loss experience, current and projected economic conditions, asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect the borrowers' ability to repay a loan (including the timing of future payments), the estimated value of any underlying collateral, composition of the loan portfolio, industry and peer bank loan quality indications and other pertinent factors, including regulatory recommendations. The allowance for credit losses on loans maintained by management is believed adequate to absorb all expected future losses in the loan portfolio at the balance sheet date. The Company disaggregates the loan portfolio into pools for purposes of determining the allowance for credit losses. These pools are based on the level at which the Company develops, documents and applies a systematic methodology to determine the allowance for credit losses. Loans with similar risk characteristics are collectively evaluated resulting in loss estimates as determined by applying reserve factors, such as historical lifetime loan loss experience, concentration risk of specific loan types, the volume, growth and composition of the Company’s loan portfolio, current economic conditions and reasonable and supportable forecasted economic conditions that may affect the borrower’s ability to pay and the value of collateral, the evaluation of the Company’s loan portfolio through its internal loan review process, general economic conditions and other qualitative risk factors both internal and external to the Company and other relevant factors, designed to estimate current expected credit losses, to amortized cost balances over the remaining contractual life of the collectively evaluated portfolio. Loans with similar risk characteristics are aggregated into homogeneous pools for assessment. Historical lifetime loan loss experience is determined by utilizing an open-pool (“cumulative loss rate”) methodology. Adjustments to the historical lifetime loan loss experience are made for differences in current loan pool risk characteristics such as portfolio concentrations, delinquency, nonaccrual, and watch list levels, as well as changes in current and forecasted economic conditions such as unemployment rates, property and collateral values, and other indices relating to economic activity. Losses are predicted over a period of time determined to be reasonable and supportable, and at the end of the reasonable and supportable period losses are reverted to long term historical averages. The reasonable and supportable period and reversion period are re-evaluated each year by the Company and are dependent on the current economic environment among other factors. A reasonable and supportable period of twelve months was utilized for all loan pools, followed by an immediate reversion to long term averages. Based on a review of these factors for each loan type, the Company applies an estimated percentage to the outstanding balance of each loan type. Loans that no longer share risk characteristics with the collectively evaluated loan pools are evaluated on an individual basis and are excluded from the collectively evaluated pools. In order to assess which loans are to be individually evaluated, the Company follows a loan review program to evaluate the credit risk in the total loan portfolio and assigns risk grades to each loan. Individual credit loss estimates are typically performed for nonaccrual loans, modified loans and all other loans identified by management. All loans deemed as being individually evaluated are reviewed on a quarterly basis in order to determine whether a specific loan loss reserve is required. The Company considers certain loans to be collateral dependent if the borrower is experiencing financial difficulty and management expects repayment for the loan to be substantially through the operation or sale of the collateral. For collateral dependent loans, loss estimates are based on the fair value of collateral, less estimated costs to sell and outstanding property taxes (if applicable). Collateral values supporting individually evaluated loans are assessed quarterly and appraisals are typically obtained at least annually. Regarding collateral dependent loans, the Company allocates a specific loan loss reserve on an individual loan basis primarily based on the value of the collateral securing the individually evaluated loan. Through this loan review process, the Company assesses the overall quality of the loan portfolio and the adequacy of the allowance for credit losses on loans while considering risk elements attributable to particular loan types in assessing the quality of individual loans. In addition, for each category of loans, the Company considers secondary sources of income and the financial strength and credit history of the borrower and any guarantors. A change in the allowance for credit losses on loans can be attributable to several factors, most notably specific reserves for individually evaluated loans, historical lifetime loan loss information, and changes in economic factors and growth in the loan portfolio. Specific reserves that are calculated on an individual basis and the qualitative assessment of all other loans reflect current changes in the credit quality of the loan portfolio. Historical lifetime credit losses, on the other hand, are based on an open-pool (“cumulative loss rate”) methodology, which is then applied to estimate lifetime credit losses in the loan portfolio. The allowance for credit losses on loans is further determined by the size of the loan portfolio subject to the allowance methodology and factors that include Company-specific risk indicators and general economic conditions, both of which are constantly changing. The Company evaluates the economic and portfolio-specific factors on a quarterly basis to determine a qualitative component of the general valuation allowance. These factors include current economic metrics, reasonable and supportable forecasted economic metrics, delinquency trends, credit concentrations, nature and volume of the portfolio and other adjustments for items not covered by specific reserves and historical lifetime loss experience. Based on the Company’s actual historical lifetime loan loss experience relative to economic and loan portfolio-specific factors at the time the losses occurred, management is able to identify the probable level of lifetime losses as of the date of measurement. The Company’s analysis of qualitative, or economic, factors on pools of loans with common risk characteristics, in combination with the quantitative historical lifetime loss information and specific reserves, provides the Company with an estimate of lifetime losses. The calculation of current expected credit losses is inherently subjective, as it requires management to exercise judgment in determining appropriate factors used to determine the allowance. The estimated loan losses for all loan pools are adjusted for changes in qualitative factors not inherently considered in the quantitative analyses to bring the allowance to the level management believes is appropriate based on factors that have not otherwise been fully accounted for, including adjustments for foresight risk, input imprecision and model imprecision. The qualitative categories and the measurements used to quantify the risks within each of these categories are subjectively selected by management, but measured by objective measurements period over period. The data for each measurement may be obtained from internal or external sources. The current period measurements are evaluated and assigned a factor commensurate with the current level of risk relative to past measurements over time. The resulting qualitative adjustments are applied to the relevant collectively evaluated loan portfolios. These adjustments are based upon quarterly trend assessments in portfolio concentrations, changes in lending policies and procedures, policy exceptions, independent loan review results, internal risk ratings and peer group credit quality trends. The qualitative allowance allocation, as determined by the processes noted above, is increased or decreased for each loan pool based on the assessment of these various qualitative factors. The determination of the appropriate qualitative adjustment is based on management's analysis of current and expected economic conditions and their impact to the portfolio, as well as internal credit risk movements and a qualitative assessment of the lending environment, including underwriting standards. Management recognizes the sensitivity of various assumptions made in the quantitative modeling of expected losses and may adjust reserves depending upon the level of uncertainty that currently exists in one or more assumptions. While policies and procedures used to estimate the allowance for credit losses on loans, as well as the resultant provision for credit losses charged to income, are considered adequate by management and are reviewed periodically by regulators and internal audit, they are approximate and could materially change based on changes within the loan portfolio and effects from economic factors. There are factors beyond the Company’s control, such as changes in projected economic conditions, including political instability or global events affecting the U.S. economy, real estate markets or particular industry conditions which could cause changes to expectations for current conditions and economic forecasts that could result in an unanticipated increase in the allowance and may materially impact asset quality and the adequacy of the allowance for credit losses and thus the resulting provision for credit losses. In assessing the adequacy of the allowance for credit losses on loans, the Company considers the results of its ongoing independent loan review process. The Company undertakes this process both to ascertain those loans in the portfolio with elevated credit risk and to assist in its overall evaluation of the risk characteristics of the entire loan portfolio. Its loan review process includes the judgment of management, independent internal loan reviewers and reviews that may have been conducted by third-party reviewers including regulatory examiners. The Company incorporates relevant loan review results in the allowance. Losses are estimated over the remaining contractual terms of loans, adjusted for prepayments. The contractual term excludes expected extensions, renewals and modifications unless management has a reasonable expectation at the reporting date that a troubled loan modification will be executed or such renewals, extensions or modifications are included in the original loan agreement and are not unconditionally cancellable by the Company. Credit losses are estimated on the amortized cost basis of loans, which includes the principal balance outstanding, purchase discounts and premiums and deferred loan fees and costs. Loan losses are not estimated for accrued interest receivable as interest that is deemed uncollectible is written off through interest income in a timely manner. Accrued interest is presented separately on the balance sheets and, as allowed under Accounting Standards Codification (“ASC”) Topic 326 - Measurement of Credit Losses on Financial Instruments (“ASC Topic 326”), is excluded from the tabular loan disclosures in Note 5 – Loans and Allowance for Credit Losses. Allowance for Credit Losses on Unfunded Commitments — The Company estimates expected credit losses over the contractual term in which the Company is exposed to credit risk through a contractual obligation to extend credit, unless the obligation is unconditionally cancellable by the Company. The allowance for credit losses on unfunded commitments is recorded on the balance sheet in other liabilities and is adjusted as a provision for (or reversal of) credit loss expense. The estimates are determined based on the likelihood of funding during the contractual term and an estimate of credit losses subsequent to funding. Estimated credit losses on subsequently funded balances are based on the same assumptions as used to estimate credit losses on existing funded loans. Allowance for Credit Losses - Securities Available for Sale — For securities classified as available for sale that are in an unrealized loss position at the balance sheet date, the Company first assesses whether or not it intends to sell the security, or more likely than not will be required to sell the security, before recovery of its amortized cost basis. If either criteria is met, the security’s amortized cost basis is written down to fair value through net income. If neither criteria is met, the Company evaluates whether any portion of the decline in fair value is the result of credit deterioration. Such evaluations consider the extent to which the amortized cost of the security exceeds its fair value, changes in credit ratings and any other known adverse conditions related to the specific security. If the evaluation indicates that a credit loss exists, an allowance for credit losses is recorded through provisions for credit losses for the amount by which the amortized cost basis of the security exceeds the present value of cash flows expected to be collected, limited by the amount by which the amortized cost exceeds fair value. Losses are charged against the allowance when management believes the uncollectibility of an available for sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Any impairment not recognized in the allowance for credit losses is recognized in other comprehensive income. For certain types of debt securities, such as U.S. Treasuries and other securities with government guarantees, entities may expect zero credit losses. Accrued interest receivable on securities available for sale totaled $7.2 million at December 31, 2024 and is excluded from the estimate of credit losses Loans acquired in a business combination — The Company records purchased credit deteriorated (“PCD”) loans, defined as a more-than-insignificant deterioration in credit quality since origination or issuance, at the purchase price plus the allowance for credit losses expected at the time of acquisition. Under this method, there is no credit loss expense affecting net income on acquisition of PCD loans. Changes in estimates of expected losses after acquisition are recognized as credit loss expense (or reversal of credit loss expense) in subsequent periods. Any noncredit discount or premium resulting from the acquisition of purchased loans with credit deterioration was allocated to each individual loan. The determination of PCD classification on acquired loans can have a significant impact on the accounting for these loans. At acquisition date, the initial allowance for PCD loans that do not share risk characteristics with pooled PCD loans, are evaluated by the Company on an individual loan basis. The expected credit loss was measured based on net realizable value, that is, the difference between the discounted value of the expected future cash flows, based on the original effective interest rate, and the amortized cost basis of the loan. For these loans, the Company recognizes expected credit loss equal to the amount by which the net realizable value of the loan is less than the amortized cost basis of the loan (which is net of previous charge-offs), except when the loan is collateral dependent, that is, when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. In these cases, expected credit loss was measured as the difference between the amortized cost basis of the loan and the fair value of the collateral. The fair value of the collateral is adjusted for the estimated costs to sell the loan if repayment or satisfaction of a loan is dependent on the sale (rather than only on the operation) of the collateral. The noncredit discount or premium, after the adjustment for the allowance for credit losses, shall be accreted to interest income using the interest method based on the effective interest rate determined after the adjustment for credit losses at the adoption date. Individually evaluated PCD loans were $12.4 million and the associated allowance for credit losses was $433 thousand at December 31, 2024. A purchased financial asset that does not qualify as a PCD asset is accounted for similar to an originated financial asset. Generally, this means that an entity recognizes the allowance for credit losses for non-PCD assets through net income at the time of acquisition. In addition, both the credit discount and noncredit discount or premium resulting from acquiring a pool of purchased financial assets that do not qualify as PCD assets shall be allocated to each individual asset. This combined discount or premium shall be accreted to interest income using the effective yield method. The fair value of acquired loans involved third-party estimates utilizing input assumptions by management which may be complex or uncertain. The determination of the fair value of acquired loans is based on a discounted cash flow methodology that considers factors such as type of loan and related collateral, and requires management’s judgement on estimates about discount rates, expected future cash flows, market conditions and other future events. For PCD loans, an estimate of expected credit losses was made and added to the purchase price to establish the initial amortized cost basis of the PCD loans. Any difference between the unpaid principal balance and the amortized cost basis is considered to relate to noncredit factors and results in a discount or premium. Discounts and premiums are recognized through interest income on an effective yield method over the life of the loans. For acquired loans not deemed PCD at acquisition, the differences between the initial fair value and the unpaid principal balance are recognized as interest income on an effective-yield basis over the lives of the related loans. For further discussion of our loan accounting and acquisitions, see Note 2 – Acquisitions and Note 5 – Loans and Allowance for Credit Losses. Collateral Dependent Loans with Specific Allocation of Allowance for Credit Losses on Loans —A loan is considered to be a collateral dependent loan when, based on current information and events, the Company expects repayment of the financial assets to be provided substantially through the operation or sale of the collateral and the Company has determined that the borrower is experiencing financial difficulty as of the measurement date. The allowance for credit losses on loans is measured by estimating the fair value of the loan based on the present value of expected cash flows, the market price of the loan, or the underlying fair value of the loan’s collateral. For real estate loans, fair value of the loan’s collateral is generally determined by third-party appraisals or internal evaluations, which are then adjusted for the estimated selling and closing costs related to liquidation of the collateral. For this asset class, the actual valuation methods (income, sales comparable, or cost) vary based on the status of the project or property. For example, land is generally based on the sales comparable method while construction is based on the income and/or sales comparable methods. The unobservable inputs may vary depending on the individual assets with no one of the three methods being the predominant approach. The Company reviews the third-party appraisal for appropriateness and adjusts the value downward to consider selling and closing costs, which typically range from 5% to 10% of the appraised value. For non-real estate loans, fair value of the loan’s collateral may be determined using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business.
Premises and Equipment	Premises and Equipment —Premises and equipment is carried at cost less accumulated depreciation. Depreciation expense is calculated principally using the straight-line method over the estimated useful lives of the assets which range fro m 3 to 39 years. Leasehold improvements are amortized using the straight-line method over the periods of the leases or the estimated useful lives, whichever is shorter. Land is carried at cost.
Leases	Leases —The Company leases certain branch locations, office facilities and equipment under operating leases. Leases with an initial term of 12 months or less are considered short-term and are not recorded on the balance sheet and the related lease expense is recognized on a straight-line basis over the lease term. For operating leases other than those considered to be short-term, the Company recognizes lease right-of-use assets and related lease liabilities. Such amounts are reported as components of premises and equipment and other liabilities, respectively, on the consolidated balance sheet. The Company owns certain office facilities which it leases to outside parties under operating lessor leases; however, such leases are not significant. Lease payments over the expected term are discounted using the Company’s incremental borrowing rate for borrowings of similar terms. Generally, the Company cannot be reasonably certain about whether or not it will renew a lease until such time as the lease is within the last two years of the existing lease term. When the Company is reasonably certain that a renewal option will be exercised, it measures/remeasures the right-of-use asset and related lease liability using the lease payments specified for the renewal period or, if such amounts are unspecified, the Company generally assumes an increase (evaluated on a case-by-case basis in light of prevailing market conditions) in the lease payment over the final period of the existing lease term. The depreciable lives of leased assets are limited by the expected lease term.
Other Repossessed Assets	Other Repossessed Assets —Assets acquired through or instead of loan foreclosure are held for sale and are initially recorded at fair value less estimated selling costs when acquired, establishing a new cost basis. Costs after acquisition are generally expensed. If the fair value of the asset declines, a write-down is recorded through expense. The valuation of foreclosed assets is subjective in nature and may be adjusted in the future because of changes in economic conditions. At December 31, 2024, the balance of other repossessed assets was $1.7 million
Federal Home Loan Bank ("FHLB") Stock	Federal Home Loan Bank (“FHLB”) Stock— The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income.
Bank Owned Life Insurance	Bank-Owned Life Insurance— The Company purchased bank-owned life insurance policies on certain key executives and acquired life insurance policies in conjunction with mergers and acquisitions. Bank-owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value, and the most reasonable estimate of fair value, adjusted for other charges or other amounts due that are probable at settlement.
Goodwill	Goodwill —Goodwill resulting from business combinations is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill is assessed annually for impairment or more frequently if events and circumstances exist that indicate that the carrying amount of the asset may not be recoverable and a goodwill impairment test should be performed. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include, among others: a significant decline in our expected future cash flows; a sustained, significant decline in our stock price and market capitalization; a significant adverse change in legal factors or in the business climate; adverse action or assessment by a regulator; and unanticipated competition. Any adverse change in these factors could have a significant impact on the recoverability of these assets and could have a material impact on the Company’s consolidated financial statements. Goodwill is the only intangible asset with an indefinite life on the Company’s balance sheet.
Core Deposit Intangibles	Core Deposit Intangibles —Core deposit intangibles arising from acquisitions are amortized using a straight-line or accelerated amortization method over their estimated useful lives, which is seven
Borrowed Funds	Borrowed Funds —The Company has a credit agreement with another financial institution. The Company pledged its shares in the Bank’s stock as collateral for the borrowing.
Loan Commitments and Related Financial Instruments	Loan Commitments and Related Financial Instruments —Financial instruments include off-balance sheet credit instruments, such as commitments to extend credit, issued to meet customer financing needs. The face amount for these items represents a promise to lend before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Derivative Financial Instruments	Derivative Financial Instrument s—Derivatives are recorded at fair value in other assets or other liabilities on the balance sheet. Derivatives executed with the same counterparty are generally subject to master netting arrangements. Fair value amounts recognized for derivatives and fair value amounts recognized for the right/obligation to reclaim/return cash collateral are not offset for financial reporting purposes. For derivative instruments that are designated and qualify for hedge accounting, the aggregate fair value of the derivative instrument is recorded in other assets or other liabilities with any gain or loss related to changes in fair value recorded in accumulated other comprehensive income, net of tax. The gain or loss is reclassified into earnings in the same period during which the hedged asset or liability affects earnings and is presented in the same income statement line item as the earnings effect of the hedged asset or liability. The Company had no derivative instruments that qualified for hedge accounting during 2024 or 2023.
Stock Based Compensation	Stock-Based Compensation —Compensation cost is recognized for stock options, restricted stock awards, performance share units (“PSUs”) and performance share awards (“PSAs”) issued to employees and directors, based on the fair value of these awards at the date of grant. The expense associated with stock-based compensation is recognized over the required service period, generally defined as the vesting period of each individual arrangement. The fair value of stock options granted are estimated at the date of grant using the Black-Scholes model. The fair value of restricted stock awards is the grant date market price of our stock. The grant date fair value of the PSUs and PSAs are based on the probable outcome of the applicable performance conditions and is calculated at target based on a combination of the closing market price of our common stock at grant date and a Monte Carlo simulated fair value in accordance with ASC 718. The impact of forfeitures of share-based payment awards on compensation expense is recognized as they occur. PSUs and PSAs are contingent upon performance and service conditions, which affect the number of shares ultimately issued. The Company periodically evaluates the probable outcome of the performance conditions and makes cumulative adjustments to compensation expense as appropriate.
Income Taxes	Income Taxes —Income tax expense is the total of the current year income tax due and the change in deferred tax assets or liabilities. Deferred tax assets and liabilities are recognized for the estimated tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and are recorded in other assets on the Company’s consolidated balance sheets. The Company records uncertain tax positions on the basis of a two-step process whereby (1) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more likely than not recognition threshold, the Company recognizes the largest amount of tax benefit that is greater than 50 percent likely of being realized upon ultimate settlement with the related tax authority. For tax positions not meeting the more likely than not test, no tax benefit is recorded. Any interest and/or penalties related to income taxes are reported as a component of income tax expense. The Company files a consolidated federal income tax return.
Comprehensive income	Comprehensive income —Comprehensive income consists of net income and other comprehensive income which includes unrealized gains and losses on securities available for sale, which are also recognized as separate components of equity, net of tax.
Fair Value of Financial Instruments	Fair Value of Financial Instruments —Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect these estimates.
Operating Segments	Operating Segments— While management monitors the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. All of the financial service operations are considered by management to be aggregated in one reportable operating segment.
Reclassifications	Reclassifications —Certain items in the prior year financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year net income or shareholders’ equity.
Earnings per Common Share	Earnings per Common Share —Basic earnings per common share is calculated as net income divided by the weighted average number of common shares outstanding during the period. Diluted earnings per common share is computed using the weighted-average number of common shares determined for the basic earnings per common share computation plus the potential dilutive effect of stock compensation using the treasury stock 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.
Loss Contingencies	Loss Contingencies —Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are such matters that will have a material effect on the financial statements.
Dividend Restrictions	Dividend Restrictions —Banking regulations require maintaining certain capital levels and may limit the dividends paid by the Bank to the Company or by the Company to its shareholders. In addition, the Company’s credit agreement with another financial institution also limits its ability to pay dividends.
Revenue from Contracts with Customers	Revenue from Contracts with Customers —The Company records revenue from contracts with customers in accordance with ASC Topic 606, “Revenue from Contracts with Customers” (“ASC Topic 606”). Under ASC Topic 606, the Company must identify the contract with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the Company satisfies a performance obligation. Significant revenue has not been recognized in the current reporting period that results from performance obligations satisfied in previous periods. The Company’s primary sources of revenue are derived from interest and dividends earned on loans, investment securities, and other financial instruments that are not within the scope of ASC Topic 606. The Company has evaluated the nature of its contracts with customers and determined that further disaggregation of revenue from contracts with customers into more granular categories beyond what is presented in the consolidated statements of income was not necessary. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Because performance obligations are satisfied as services are rendered and the transaction prices are fixed, the Company has made no significant judgments in applying the revenue guidance prescribed in ASC Topic 606 that affect the determination of the amount and timing of revenue from contracts with customers.
New Accounting Standards	New Accounting Standards Recent Accounting Standards ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures .” ASU 2023-07 expands segment disclosure requirements for public entities to require disclosure of significant segment expenses and other segment items on an annual and interim basis and to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. ASU 2023-07 became effective for the Company’s annual financial statements in 2024 and will be effective for interim periods following. ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” . This update requires that public business entities on an annual basis (1) disclose specific categories in the tax rate reconciliation, (2) provide additional information for reconciling items that meet a quantitative threshold and (3) disaggregate income taxes paid by jurisdiction. ASU 2023-09 is effective for annual reporting periods beginning after December 15, 2024. Early adoption is permitted. The Company is evaluating the impact of this ASU, but does not believe it will have a significant impact on the Company’s financial statements. ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses” . This update requires that public businesses disclose details about specific expenses such as inventory purchases, employee compensation, depreciation, amortization and depletion. ASU 2023-09 is effective for annual reporting periods beginning after December 15, 2026. Early adoption is permitted. The Company is evaluating the impact of this ASU, but does not believe it will have a significant impact on the Company’s financial statements.
