Explanatory Note

On January 2, 2025, SouthState Corporation, a South Carolina corporation (“SouthState” or the “Company”), filed a Current Report on Form 8-K (the “Initial Form 8-K”) to announce the completion of its acquisition of Independent Bank Group, Inc., a Texas corporation (“Independent”), on January 1, 2025, pursuant to the Agreement and Plan of Merger, dated as of May 17, 2024. Immediately following the merger, Independent’s wholly owned banking subsidiary, Independent Bank (d/b/a Independent Financial), merged with and into SouthState’s wholly owned banking subsidiary, SouthState Bank, National Association (the “Bank Merger”), with SouthState Bank, National Association surviving the Bank Merger and continuing as the surviving bank.

This Form 8-K/A amends and supplements the Initial Form 8-K, solely to provide the financial statements and pro forma financial information relating to the merger required by Items 9.01(a) and 9.01(b) of Form 8-K and should be read in conjunction with the Initial Form 8-K. This amendment report does not include other updates or amendments to the Initial Form 8-K. The pro forma financial information included in this amendment has been presented for informational purposes only, as required by Form 8-K. It does not purport to represent the actual results of operations that the Company and Independent would have achieved had the companies been combined during the periods presented in the pro forma financial information and is not intended to project the future financial results and results of operations that the combined company may achieve after completion of the merger. In addition, the fair value assessments presented in the pro forma condensed financial information are the preliminary assessments used in the merger modeling announced previously, as the purchase accounting entries have not yet been finalized, and are based upon available information and certain assumptions, which SouthState believes are reasonable under the circumstances. Actual results may differ materially from the assumptions within the unaudited pro forma condensed combined financial statements.

Cautionary Statement Regarding Forward Looking Statements

Statements included in this communication, which are not historical in nature are intended to be, and are hereby identified as, forward-looking statements for purposes of the safe harbor provided by Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements are based on, among other things, management’s beliefs, assumptions, current expectations, estimates and projections about the financial services industry, the economy and SouthState. Words and phrases such as “may,” “approximately,” “continue,” “should,” “expects,” “projects,” “anticipates,” “is likely,” “look ahead,” “look forward,” “believes,” “will,” “intends,” “estimates,” “strategy,” “plan,” “could,” “potential,” “possible” and variations of such words and similar expressions are intended to identify such forward-looking statements.

SouthState Corporation (“SouthState” or the “Company”) cautions readers that forward looking statements are subject to certain risks, uncertainties and assumptions that are difficult to predict with regard to, among other things, timing, extent, likelihood and degree of occurrence, which could cause actual results to differ materially from anticipated results. Such risks, uncertainties and assumptions, include, among others, the following: (1) economic volatility risk, including inflation, potentially resulting in higher rates, deterioration in the credit markets, greater than expected noninterest expenses, excessive loan losses, or on the other hand lower rates, which also may have other negative consequences, which risks could be exacerbated by potential negative economic developments resulting from federal spending cuts and/or one or more federal budget-related impasses or actions; (2) risks related to the ability of the Company to pursue its strategic plans which depend upon certain growth goals in our lines of business; (3) risks related to the merger and integration of SouthState and Independent Bank Group, Inc. (“Independent”) including, among others, (i) the risk that the cost savings and any revenue synergies from the merger may not be fully realized or may take longer than anticipated to be realized, (ii) the risk that the integration of Independent’s operations into SouthState’s operations will be materially delayed or will be more costly or difficult than expected or that the parties are otherwise unable to successfully integrate Independent’s businesses into SouthState’s businesses, (iii) the amount of the costs, fees, expenses and charges related to the merger, and (iv) reputational risk and the reaction of each company's customers, suppliers, employees or other business partners to the merger; (4) risks relating to the ability to retain our culture and attract and retain qualified people as we grow and are located in new markets, and being able to offer competitive salaries and benefits, including flexibility of working remotely or in the office; (5) deposit attrition, client loss or revenue loss following completed mergers or acquisitions that may be greater than anticipated; (6) credit risks associated with an obligor’s failure to meet the terms of any contract with SouthState Bank, N.A. (the “Bank”) or otherwise fail to perform as agreed under the terms of any loan-related document; (7) interest rate risk primarily resulting from our inability to effectively manage the risk, and their impact on the Bank’s earnings, including from the correspondent and mortgage divisions, housing demand, the market value of the Bank’s loan and securities portfolios, and the market value of SouthState’s equity; (8) a decrease in our net interest income due to the interest rate environment; (9) liquidity risk affecting the Bank’s ability to meet its obligations when they come due; (10) unexpected outflows of uninsured deposits may require us to sell investment securities at a loss; (11) potential deterioration in real estate values; (12) the loss of value of our investment portfolio could negatively impact market perceptions of us and could lead to deposit withdrawals; (13) price risk focusing on changes in market factors that may affect the value of traded instruments in “mark-to-market” portfolios; (14) transaction risk arising from problems with service or product delivery; (15) the impact of increasing digitization of the banking industry and movement of customers to on-line platforms, and the possible impact on the Bank’s results of operations, customer base, expenses, suppliers and operations; (16) controls and procedures risk, including the potential 3

failure or circumvention of our controls and procedures or failure to comply with regulations related to controls and procedures; (17) volatility in the financial services industry (including failures or rumors of failures of other depository institutions), along with actions taken by governmental agencies to address such turmoil, could affect the ability of depository institutions, including us, to attract and retain depositors and to borrow or raise capital; (18) the impact of competition with other financial institutions, including deposit and loan pricing pressures and the resulting impact, including as a result of compression to net interest margin; (19) compliance risk involving risk to earnings or capital resulting from violations of or nonconformance with laws, rules, regulations, prescribed practices, or ethical standards, and contractual obligations regarding data privacy and cybersecurity; (20) regulatory change risk resulting from new laws, rules, regulations, accounting principles, proscribed practices or ethical standards, including, without limitation, the possibility that regulatory agencies may require higher levels of capital above the current regulatory-mandated minimums and including the impact of special FDIC assessments, the Consumer Financial Protection Bureau regulations or other guidance, and the possibility of changes in accounting standards, policies, principles and practices; (21) risks related to the legal, regulatory, and supervisory environment, including changes in financial services legislation, regulation, policies, or government officials or other personnel; (22) strategic risk resulting from adverse business decisions or improper implementation of business decisions; (23) reputation risk that adversely affects earnings or capital arising from negative public opinion including the effects of social media on market perceptions of us and banks generally; (24) cybersecurity risk related to the dependence of SouthState on internal computer systems and the technology of outside service providers, as well as the potential impacts of internal or external security breaches, which may subject the Company to potential business disruptions or financial losses resulting from deliberate attacks or unintentional events; (25) reputational and operational risks associated with environment, social and governance (ESG) matters, including the impact of changes in federal and state laws, regulations and guidance relating to climate change; (26) excessive loan losses; (27) reputational risk and possible higher than estimated reduced revenue from previously announced or proposed regulatory changes in the Bank’s consumer programs and products; (28) operational, technological, cultural, regulatory, legal, credit and other risks associated with the exploration, consummation and integration of potential future acquisitions, whether involving stock or cash consideration; (29) catastrophic events such as hurricanes, tornados, earthquakes, floods or other natural or human disasters, including public health crises and infectious disease outbreaks, as well as any government actions in response to such events, and the related disruption to local, regional and global economic activity and financial markets, and the impact that any of the foregoing may have on SouthState and its customers and other constituencies; (30) geopolitical risk from terrorist activities and armed conflicts that may result in economic and supply disruptions, and loss of market and consumer confidence; (31) the risks of fluctuations in market prices for SouthState common stock that may or may not reflect economic condition or performance of SouthState; (32) the payment of dividends on SouthState common stock, which is subject to legal and regulatory limitations as well as the discretion of the board of directors of SouthState, SouthState’s performance and other factors; (33) ownership dilution risk associated with potential acquisitions in which SouthState’s stock may be issued as consideration for an acquired company; and (34) other factors that may affect future results of SouthState, as disclosed in SouthState’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K, filed by SouthState with the U.S. Securities and Exchange Commission (“SEC”) and available on the SEC’s website at http://www.sec.gov, any of which could cause actual results to differ materially from future results expressed, implied or otherwise anticipated by such forward-looking statements.

All forward-looking statements speak only as of the date they are made and are based on information available at that time. SouthState does not undertake any obligation to update or otherwise revise any forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by federal securities laws.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of SouthState Corporation, as successor by merger to Independent Bank Group, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Independent Bank Group, Inc. and its subsidiaries (the Company) as of December 31, 2024 and 2023, the related consolidated statements of income, comprehensive income, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2024, and the related notes to the consolidated financial statements (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB) and auditing standards generally accepted in the United States of America (GAAS), the Company's internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in 2013, and our report dated February 21, 2025 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB and GAAS. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Emphasis of Matter – Subsequent Merger

As described in Notes 1 and 23 to the financial statements, subsequent to the balance sheet date, the Company merged into SouthState Corporation pursuant to the Agreement and Plan of Merger dated as of May 17, 2024. Our opinion is not modified with respect to this matter.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Allowance for Credit Losses on Loans

As described in Notes 1 and 5 of the consolidated financial statements, the Company’s allowance for credit losses on loans totaled $133.0 million as of December 31, 2024. The allowance for credit losses on loans is measured on a collective basis for portfolios of loans when similar risk characteristics exist. Loans that do not share risk characteristics are evaluated for expected credit losses on an individual basis and excluded from the collective evaluation. For determining the appropriate allowance for credit losses on a collective basis, the loan portfolio is segmented into pools based upon similar risk characteristics and a lifetime loss-rate model is utilized. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, credit quality, or term as well as changes in environmental conditions, such as changes in unemployment rates, gross domestic product, property values, various price indices, or other relevant factors. Management has determined that they are reasonably able to forecast the macroeconomic variables used in the modeling processes and assign probability weighting to those scenarios with an acceptable degree of confidence for a total of two years then encompassing a reversion process whereby the forecasted macroeconomic variables are reverted to their historical mean utilizing a rational, systematic basis. Management qualitatively adjusts model results for risk factors that are not considered within the modeling processes but are nonetheless relevant in assessing the expected credit losses within the loan pools. These qualitative factor adjustments may increase or decrease management's estimate of expected credit losses by a calculated percentage or amount based upon the estimated level of risk. The determination of the forecasts and qualitative factors requires a significant amount of judgment by management and the estimate is highly sensitive to changes in significant assumptions.

We identified the determination of forecasts and qualitative factors applied to the allowance for credit losses on loans as a critical audit matter because auditing the forecasts and qualitative factors required a high degree of auditor judgment, as the estimate is highly sensitive to changes in significant assumptions.

Our audit procedures related to the forecasts and qualitative factors applied to the allowance for credit losses on loans included the following, among others:

We obtained an understanding of the relevant controls related to the development and weighting of forecasts and qualitative factors and tested such controls for design and operating effectiveness, including controls over management’s establishment, review and approval of the

4

forecasts and qualitative factors and data used in determining the forecasts and qualitative factors.

We tested management’s process and evaluated the reasonableness of their judgements and assumptions to develop the forecasts and qualitative factors, which included:

Testing the accuracy of the data inputs used by management as a basis for the forecasts and qualitative factors by comparing to internal and external source data and assessing the reasonableness of the magnitude and directional consistency of the adjustments for such.
Evaluating whether management’s conclusions related to forecasts and weighting of forecasts were consistent with Company provided internal data and external or independently sourced data, and agreeing the impact to the allowance calculation.

Note 1. Summary of Significant Accounting Policies

Nature of operations: Independent Bank Group, Inc. (IBG) through its subsidiary, Independent Bank, a Texas state banking corporation, doing business as Independent Financial (Bank) (collectively known as the Company), provides a full range of banking services to individual and corporate customers in the North, Central and Southeast, Texas areas and along the Colorado Front Range, through its various branch locations in those areas. The Company is engaged in traditional community banking activities, which include commercial and retail lending, deposit gathering, and investment and liquidity management activities. The Company’s primary deposit products are demand deposits, money market accounts and certificates of deposit, and its primary lending products are commercial business and real estate, real estate mortgage and consumer loans.

Merger with SouthState Corporation: On May 20, 2024, the Company and SouthState Corporation (SSB) jointly announced the signing of a definitive merger agreement, dated May 17, 2024, to merge the two companies in an all-stock transaction with SSB continuing as the surviving entity. SSB is headquartered in Winter Haven, Florida and has full-service locations in Florida, Alabama, Georgia, South Carolina, North Carolina and Virginia. The merger closed on January 1, 2025 as described in Note 23. Subsequent Event.

Basis of presentation: The accompanying consolidated financial statements include the accounts of IBG and all other entities in which IBG has controlling financial interest. All material intercompany transactions and balances have been eliminated in consolidation. In addition, the Company wholly-owns nine statutory business trusts that were formed for the purpose of issuing trust preferred securities and do not meet the criteria for consolidation (See Note 11. Junior Subordinated Debentures).

Accounting standards codification: The Financial Accounting Standards Board's (FASB) Accounting Standards Codification (ASC) is the officially recognized source of authoritative U.S. generally accepted accounting principles (GAAP) applicable to all public and non-public non-governmental entities. Prior to the merger with SSB on January 1, 2025, the Company was a Securities and Exchange Commission (SEC) registrant. Rules and interpretive releases of the SEC under the authority of federal securities laws are also sources of authoritative GAAP for SEC registrants. All other accounting literature is considered non-authoritative.

Segment reporting: The Company has one reportable segment. The Company’s chief operating decision-maker (CODM) uses consolidated results to make operating and strategic decisions. See Note 21. Segment Information.

Reclassifications: Certain prior period financial statement and disclosure amounts have been reclassified to conform to current period presentation. The reclassifications have no effect on net income or stockholders' equity as previously reported.

Use of estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Accordingly, actual results could differ from those estimates. The material estimates included in the financial statements relate to the allowance for credit losses, the valuation of goodwill and valuation of assets and liabilities acquired in business combinations. 12

Cash and cash equivalents: For the purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks and federal funds sold. All highly liquid investments with an initial maturity of less than ninety days are considered to be cash equivalents. The Company maintains deposits with other financial institutions in amounts that exceed FDIC insurance coverage. The Company's management monitors the balance in these accounts and periodically assesses the financial condition of the other financial institutions. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risks on cash or cash equivalents.

Restricted cash: The Company maintains cash collateral balances which have been pledged to derivative counterparties and are legally restricted as to use.

Certificates of deposit: Certificates of deposit are FDIC insured deposits in other financial institutions with original maturities of five years or less and are carried at cost.

Securities: Debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and recorded at amortized cost. Debt securities that the Company intends to hold for an indefinite period of time, but not necessarily to maturity are classified as available for sale. Securities available for sale are reported at fair value with unrealized gains or losses reported as a separate component of other comprehensive income, net of tax. Any decision to sell a security classified as available for sale would be based on various factors, including significant movements in interest rates, changes in the maturity mix of the Company's assets and liabilities, liquidity needs, regulatory capital considerations and other similar factors.

The amortization of premiums and accretion of discounts, computed by the interest method generally over their contractual lives, are recognized in interest income. Premiums on callable securities are amortized to their earliest call date. Realized gains or losses, determined on the basis of the cost of specific securities sold, are included in earnings on the trade date.

Loans held for sale: The Company originates residential mortgage loans that may subsequently be sold to unaffiliated third parties. The Company elected the fair value option for certain residential mortgage loans held for sale in accordance with ASC 825, Financial Instruments. This election allows for a more effective offset of the changes in fair values of the loans and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC 815, Derivatives and Hedging. The Company has not elected the fair value option for other residential mortgage loans held for sale primarily because they are not economically hedged using derivative instruments. Mortgage loans originated and intended for sale not recorded under the fair value option are carried at the lower of aggregate cost or fair value, as determined by aggregate outstanding commitments from investors. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. All mortgage loans held for sale are sold without servicing rights retained. Gains and losses on sales of loans are recognized in noninterest income at settlement dates and are determined by the difference between the sales proceeds and the carrying value of the loans. 13

Loans held for investment: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported at their outstanding principal balance, net of unearned interest, purchase premiums and discounts, deferred loan fees or costs and an allowance for credit losses. Loan origination fees, net of direct origination costs, are deferred and recognized as an adjustment to the related loan yield using the effective interest method without anticipating prepayments. Further information regarding the Company's accounting policies related to past due loans, non-accrual loans, collateral dependent loans and loan modifications to borrowers experiencing financial difficulty is presented in Note 5. Loans, Net and Allowance for Credit Losses on Loans. ****

Acquired loans: In accordance with ASC 326, Measurement of Credit Losses on Financial Instruments, loans acquired in connection with a business combination are recorded at their acquisition-date fair value. The allowance for credit losses related to the acquired loan portfolio is not carried over. Acquired loans are classified into two categories based on the credit risk characteristics of the underlying borrowers as either purchased credit deteriorated (PCD) loans, or loans with no evidence of credit deterioration (non-PCD).

PCD loans are defined as a loan or pool of loans that have experienced more-than-insignificant credit deterioration since the origination date. For PCD loans, an initial allowance is established on the acquisition date using the same methodology as other loans held for investment and combined with the fair value of the loan to arrive at acquisition date amortized cost. Accordingly, no provision for credit losses is recognized on PCD loans at the acquisition date. Subsequent to the acquisition date, changes to the allowance are recognized in the provision for credit losses.

Non-PCD loans are pooled into segments together with originated held for investment loans that share similar risk characteristics and have an allowance established on the acquisition date, which is recognized in the current period provision for credit losses.

Determining the fair value of the acquired loans involves estimating the principal and interest payment cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. For PCD loans, the non-credit discount or premium is allocated to individual loans as determined by the difference between the loan’s unpaid principal balance and amortized cost basis. The non-credit premium or discount is recognized into interest income on a level yield basis over the remaining expected life of the loan. For non-PCD loans, the fair value discount or premium is allocated to individual loans and recognized into interest income on a level yield basis over the remaining expected life of the loan.

Allowance for credit losses: In accordance with ASC 326, the Company's accounting policies are described below.

Allowance for credit losses - loans: The allowance for credit losses on loans is a valuation account that is deducted from the amortized cost basis of loans to present management's best estimate of the net amount expected to be collected. Loans, or portions thereof, are charged-off against the allowance for credit losses when management believes that collectability of the principal is unlikely. Subsequent recoveries, if any, are credited to the allowance. The allowance is increased (decreased) by provisions (or reversals of) reported in the income statement as a component of provision for credit losses. Management has made the accounting policy election to exclude accrued interest receivable on loans from the estimate of credit losses and reports accrued interest separately in other assets in the consolidated balance sheets. Further information regarding Company policies and methodology used to estimate the allowance for credit losses on loans is presented in Note 5. Loans, Net and Allowance for Credit Losses on Loans. 14

Allowance for credit losses - available for sale securities: For available for sale securities in an unrealized loss position, the Company first assesses whether it intends to sell or it is more-likely-than-not that it will be required to sell the securities before recovery of the amortized cost basis. If either of these criteria is met, the securities amortized cost basis is written down to fair value as a current period expense. If either of the above criteria is not met, the Company evaluates whether the decline in fair value is the result of credit losses or other factors. In making this assessment, management may consider various factors including the extent to which fair value is less than amortized cost, performance of any underlying collateral and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected are compared to the amortized cost basis of the security and any excess of the amortized cost basis over the present value of expected cash flows is recorded as an allowance for credit loss, limited to the amount by which the fair value is less than the amortized cost basis. Any impairment not recorded through an allowance for credit loss is recognized in other comprehensive income as a non credit-related impairment.

Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit losses. Available for sale securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by management or when either of the aforementioned criteria regarding intent or requirement to sell is met.

Allowance for credit losses - held to maturity securities: Management measures expected credit losses on held to maturity securities on a collective basis by major security type with each type sharing similar risk characteristics and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. An allowance for credit losses on held to maturity securities, if needed, is a valuation account that is deducted from the amortized cost basis of held to maturity securities to present management's best estimate of the net amount expected to be collected. Held to maturity securities are charged-off against the allowance when deemed uncollectible by management. Adjustments to the allowance are reported in the income statement as a component of provision for credit losses.

Management has made the accounting policy election to exclude accrued interest receivable on available for sale and held to maturity securities from the estimate of credit losses and report accrued interest separately in other assets in the consolidated balance sheet.

Allowance for credit losses on off-balance sheet credit exposures: The allowance for credit losses on off-balance sheet credit exposures is a liability account, calculated in accordance with ASC 326, representing expected credit losses over the contractual period for which the Company is exposed to credit risk resulting from a contractual obligation to extend credit. No allowance is recognized if we have the unconditional right to cancel the obligation. The allowance is reported as a component of other liabilities in the consolidated balance sheets. Adjustments to the allowance are reported in the income statement as a component of provision for credit losses. Further information regarding Company policies and methodology used to estimate the allowance for credit losses on off-balance sheet credit exposures is presented in Note 13. Off-Balance Sheet Arrangements, Commitments and Contingencies.

Premises and equipment, net: Land is carried at cost. Bank premises, furniture and equipment and aircraft are carried at cost, less accumulated depreciation computed principally by the straight-line method over the estimated useful lives of the assets, which range from three to thirty years. Real property acquired after January 1, 2019, accounts for depreciation using the straight-line method over the estimated useful lives of the assets considering the salvage value of the real property.

Leasehold improvements are carried at cost and are depreciated over the shorter of the estimated useful life or the lease period. 15

Software: Costs incurred in connection with development or purchase of internal use software and cloud computing arrangements, including in-substance software licenses, are capitalized. Amortization is computed on a straight-line basis over the estimated useful life of the asset, which generally ranges from one to five years. Capitalized software is included in other assets in the consolidated balance sheets.

Leases: The Company's leases are accounted for under ASC Topic 842, Leases. For operating leases with a term greater than one year, the Company recognizes operating right-of-use (ROU) lease assets and operating lease liabilities, which are recorded in other assets and other liabilities, respectively, in the consolidated balance sheets. The Company determines if an arrangement is a lease at inception. Operating ROU lease assets and related liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate referenced to the Federal Home Loan Bank Secure Connect advance rates for borrowings of similar terms in determining the present value of lease payments. The operating ROU lease asset also includes any lease pre-payments made and excludes lease incentives. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which the Company has elected to account for separately as the non-lease component amounts are readily determinable under most leases.

Long-term assets: Premises and equipment and other long-term assets are reviewed for impairment when events indicate that their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.

Other real estate owned: Real estate properties acquired through, or in lieu of, loan foreclosure are initially recorded at fair value less estimated selling costs at the date of foreclosure, establishing a new cost basis. After foreclosure, valuations are periodically performed by management and the real estate is carried at the lower of carrying amount or fair value less cost to sell.

Revenue and expenses from operations of other real estate owned and impairment charges on other real estate are included in noninterest expense. Gains and losses on sale of other real estate are included in noninterest income.

Goodwill and other intangible assets, net: Goodwill represents the excess of costs over fair value of net assets of businesses acquired. Goodwill is tested for impairment annually on December 31 or on an interim basis if an event triggering impairment may have occurred. If a reporting unit’s carrying amount exceeds its fair value, the Company will record an impairment charge based on that difference. During 2024, the Company recorded a $518,000 goodwill impairment charge as further discussed in Note 7. Goodwill and Other IntangibleAssets, Net.

Core deposit intangibles and other acquired customer relationship intangibles arising from bank acquisitions are amortized on a straight-line basis over their original estimated useful lives of ten years and thirteen years, respectively. Other intangible assets are tested for impairment whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable from future undiscounted cash flows.

Restricted 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 of Dallas and other restricted stock do not have readily determinable fair values as ownership is restricted and they lack a ready market. As a result, these stocks are carried at cost and evaluated periodically by management for impairment. Both cash and stock dividends are reported as income. 16

Bank-owned life insurance: Bank-owned life insurance is recorded at the amount that can be realized under the insurance contracts at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Changes in the net cash surrender value of the policies, as well as insurance proceeds received are reflected in noninterest income.

Income taxes: Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities (excluding deferred tax assets and liabilities related to business combinations or components of other comprehensive income). Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. The effect of a change in tax rates on deferred assets and liabilities is recognized in income taxes during the period that includes the enactment date. A valuation allowance, if needed, reduces deferred tax assets to the expected amount more likely than not to be realized. Realization of deferred tax assets is dependent upon the level of historical income, prudent and feasible tax planning strategies, reversals of deferred tax liabilities and estimates of future taxable income.

The Company evaluates uncertain tax positions at the end of each reporting period. The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefit recognized in the financial statements from any such position is measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. 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.

Loan commitments and related financial instruments: In the ordinary course of business, the Company has entered into certain off-balance sheet financial instruments consisting of commitments to extend credit, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded in the financial statements when they are funded or related fees are incurred or received.

Stock based compensation: Compensation cost is recognized for restricted stock awards/stock units issued to employees based on the market price of the Company's common stock on the grant date. Stock-based compensation expense is generally recognized using the straight-line method over the requisite service period for time-based awards. Compensation expense for performance stock units is recognized over the service period of the award based upon the probable number of units expected to vest. The impact of forfeitures of stock-based payment awards on compensation expense is recognized as forfeitures occur.

Transfers of financial assets: Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.

Advertising costs: Advertising costs are expensed as incurred. 17

Business combinations: The Company applies the acquisition method of accounting for business combinations. Under the acquisition method, the acquiring entity in a business combination recognizes 100% of the assets acquired and liabilities assumed at their acquisition date fair values. Management utilizes valuation techniques appropriate for the asset or liability being measured in determining these fair values. Any excess of the purchase price over amounts allocated to assets acquired, including identifiable intangible assets, and liabilities assumed is recorded as goodwill. Where amounts allocated to assets acquired and liabilities assumed is greater than the purchase price, a bargain purchase gain is recognized. Adjustments identified during the measurement period are recognized in the reporting period in which the adjustment amounts are determined. Acquisition-related costs are expensed as incurred.

Comprehensive income: Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities, are reported as a separate component of the equity section of the balance sheet, such items, along with net income, are components of comprehensive income. Gains and losses on available for sale securities are reclassified to net income as the gains or losses are realized upon sale of the securities. For securities transferred from available for sale to the held to maturity classification, the remaining pre-tax gains and losses will be amortized over the remaining life of the securities, as an adjustment of yield on the transferred securities. For cash flow hedges, gains and losses on the derivative(s) are recorded in accumulated other comprehensive income and subsequently reclassified into interest income in the same period that the hedged transaction affects earnings.

Fair values of financial instruments: Accounting standards define fair value, establish a framework for measuring fair value in GAAP, and require certain disclosures about fair value measurements (see Note 17. Fair Value Measurements). In general, fair values of financial instruments are based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and the Company's creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time.

Derivative financial instruments: The Company enters into certain derivative financial instruments: interest rate lock commitments, forward mortgage-backed securities trades and interest rate swaps. The accounting for changes in fair value depends on the intended use of the derivative. Changes in fair value of derivatives designated in a qualifying hedge relationship are recorded in accumulated other comprehensive income. Changes in fair value of derivatives not designated in a qualifying hedge relationship are recognized directly in earnings. All derivatives are carried at fair value in either other assets or other liabilities. See Note 18. Derivative Financial Instruments for further information regarding Company policy.

Mortgage banking revenue: This revenue category reflects the Company's mortgage production revenue, including fees and income derived from mortgages originated with the intent to sell, gains on sales of mortgage loans and the initial and subsequent changes in the fair value of the mortgage derivatives. Interest earned on mortgage loans is recorded in interest income.

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.

Revenue recognition: ASC Topic 606, Revenue from Contracts with Customers (ASC 606), establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity's contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performance obligations are satisfied. 18

The majority of the Company's revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as loans, letters of credit, and investment securities, as well as revenue related to mortgage banking activities, and BOLI, as these activities are subject to other accounting guidance. Descriptions of revenue-generating activities that are within the scope of ASC 606, and are presented in the accompanying Consolidated Statements of Income as components of noninterest income, are as follows:

Service charges on deposit accounts - these represent general service fees for monthly account maintenance and activity or transaction-based fees and consist of transaction-based revenue, time-based revenue (service period), item-based revenue or some other individual attribute-based revenue. Revenue is recognized when the performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed (such as a wire transfer). Payment for such performance obligations are generally received at the time the performance obligations are satisfied.
Investment management - includes income related to providing investment management services to customers under investment management contracts. Also included are fees received from a third party broker-dealer as part of a revenue-sharing agreement for fees earned from customers that are referred to a third party. The investment management fees and referral fees are billed and paid on a quarterly basis and recognized ratably throughout the quarter as performance obligations are satisfied.
--- ---
Mortgage warehouse purchase program fees - includes fees for the administration and funding of mortgage loans, as well as renewal and application fees received from mortgage originator customers through our mortgage warehouse purchase program. Revenue related to the warehouse program is recognized when the related loan interest is paid off or upon renewal or application.
--- ---
Gains and losses on the sale of other real estate owned - generally recognized when the performance obligation is complete which is typically at delivery of control over the property to the buyer at time of each real estate closing.
--- ---
Other noninterest income - includes the Company's correspondent bank earnings credit, acquired loan recoveries, other deposit fees, and merchant interchange income. The majority of these fees in other noninterest income are not subject to the requirements of ASC 606. The other deposit fees and merchant interchange income are in the scope of ASC 606, and payment for such performance obligations are generally received at the time the performance obligations are satisfied.
--- ---

The Company has made no significant judgments in applying the revenue guidance prescribed in ASC 606 that affect the determination of the amount and timing of revenue from the above-described contracts with customers.

Earnings (loss) per share: Basic earnings (loss) per common share is calculated as net income available to common shareholders divided by the weighted average number of common shares outstanding during the period. The unvested share-based payment awards that contain rights to non-forfeitable dividends are considered participating securities for this calculation. Diluted earnings (loss) per common share includes the dilutive effect of additional potential common shares issuable under participating nonvested restricted stock awards as well as performance stock units (PSUs). The participating nonvested restricted stock awards were not included in dilutive shares as they were anti-dilutive for the years ended December 31, 2024, 2023 and 2022. Additionally, performance stock units were not included in dilutive shares for the year ended December 31, 2024 as they were anti-dilutive. Proceeds from the assumed exercise of dilutive participating nonvested restricted stock awards and PSUs are assumed to be used to repurchase common stock at the average market price. 19

ASU 2023-01, Leases (Topic 842): Common Control Arrangements. ASU 2023-01 requires entities to amortize leasehold improvements associated with common control leases over the useful life to the common control group. ASU 2023-01 was effective for the Company on January 1, 2024. The adoption of ASU 2023-01 did not have a significant impact on the financial statements.

ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. ASU 2023-02 is intended to improve the accounting and disclosures for investments in tax credit structures. ASU 2023-02 allows entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. Previously, this method was only available for qualifying tax equity investments in low-income housing tax credit structures. ASU 2023-02 was effective for the Company on January 1, 2024. The adoption of ASU 2023-02 did not have a significant impact on the financial statements. 20

ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. ASU 2023-07 amends current guidance to require a public entity to disclose 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. Public entities with a single reporting segment are required to provide both the new disclosures and all of the existing disclosures required under ASC 280. ASU 2023-07 was effective for the Company for annual periods on January 1, 2024 and for interim periods starting in 2025. The adoption of ASU 2023-07 did not have a significant impact on the financial statements. See Note 21. Segment Information.

ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging - Portfolio Layer Method. Under prior guidance, entities can apply the last-of-layer hedging method to hedge the exposure of a closed portfolio of prepayable financial assets to fair value changes due to changes in interest rates for a portion of the portfolio that is not expected to be affected by prepayments, defaults, and other events affecting the timing and amount of cash flows. ASU 2022-01 expands the last-of-layer method, which permits only one hedge layer, to allow multiple hedged layers of a single closed portfolio. To reflect that expansion, the last-of-layer method is renamed the portfolio layer method. ASU 2022-01 also (i) expands the scope of the portfolio layer method to include non-prepayable financial assets, (ii) specifies eligible hedging instruments in a single-layer hedge, (iii) provides additional guidance on the accounting for and disclosure of hedge basis adjustments under the portfolio layer method and (iv) specifies how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. ASU 2022-01 was effective for the Company on January 1, 2023. The adoption of ASU 2022-01 did not have a significant impact on the financial statements.

ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. ASU 2022-02 eliminates the accounting guidance for troubled debt restructurings in ASC Subtopic 310-40, Receivables - Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, ASU 2022-02 requires entities to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC Subtopic 326-20, Financial Instruments - Credit Losses - Measured at Amortized Cost. ASU 2022-02 was effective for the Company on January 1, 2023. The adoption of ASU 2022-02 did not have a significant impact on the financial statements.

Issued but not yet effective accounting standards

ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 amends current guidance under ASC 740 to enhance the transparency and decision-usefulness of income tax disclosures. The guidance requires public business entities to disclose in the rate reconciliation table additional categories of information about federal, state and foreign income taxes and to provide more details about the reconciling items in some categories if the items meet a quantitative threshold. The guidance requires all entities, to disclose annually, income taxes paid (net of refunds received) disaggregated by federal, state and foreign taxes and to disaggregate the information by jurisdiction based on a quantitative threshold. ASU 2023-09 will be effective for the Company on January 1, 2025. The adoption of ASU 2023-09 is not expected to have a significant impact on the financial statements. 21

The Company's securities classified as available for sale and held to maturity are evaluated for expected credit losses by applying the appropriate expected credit losses methodology in accordance with ASC Topic 326, Financial Instruments - Credit Losses. At December 31, 2024 and 2023, management's review of all securities at an unrealized loss position determined that the losses resulted from factors not related to credit quality. This conclusion is based on management's analysis of the underlying risk characteristics, including credit ratings, and other qualitative factors for each security type in our portfolio.

The unrealized losses on available for sale securities are generally due to increases in market interest rates. Furthermore, the Company has the intent to hold the available for sale securities until maturity or a forecasted recovery, and it is more likely than not that the Company will not have to sell the securities before the recovery of their cost basis. The issuers of these securities continue to make timely principal and interest payments under the contractual terms of the securities. As such, there is no allowance for credit losses on available for sale securities recognized as of December 31, 2024 and 2023. 25

The Company's held to maturity securities include taxable and tax-exempt municipal securities issued primarily by school districts but also may include utility districts or other municipalities. With regard to securities issued by state and municipal subdivisions, management considers issuer bond ratings, historical loss rates for given bond ratings, whether issuers continue to make timely principal and interest payments under the contractual terms of the securities, internal forecasts and whether or not such securities are guaranteed. Substantially all of the Company's held to maturity securities are guaranteed by the Texas Permanent School Fund (PSF), which is a sovereign wealth fund that serves to provide revenues for funding of public primary and secondary education in the State of Texas. At December 31, 2024 and 2023, all of the Company's held to maturity securities were rated AAA/Aaa by Moody's and/or Standard & Poor's bond rating services. Furthermore, as of December 31, 2024 and 2023, there were no past due principal or interest payments associated with these securities. As such, no allowance for credit losses has been recorded on held to maturity securities as of December 31, 2024 and 2023.

The Company has certain lending policies and procedures in place that are designed to maximize loan income within an acceptable level of risk. Management reviews and approves these policies and procedures on a regular basis. A reporting system supplements the review process by providing management with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and nonperforming and potential problem loans.

Commercial loans are underwritten after evaluating and understanding the borrower’s ability to operate profitably and prudently expand its business. The Company’s management examines current and projected cash flows to determine the ability of the borrower to repay their obligations as agreed. Commercial loans are primarily made based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. These cash flows, however, may not be as expected and the value of collateral securing the loans may fluctuate. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some short-term loans may be made on an unsecured basis. 26

The commercial loan portfolio includes loans made to customers in the energy industry, which is a complex, technical and cyclical industry. Experienced bankers with specialized energy lending experience originate our energy loans. Companies in this industry produce, extract, develop, exploit and explore for oil and natural gas. Loans are primarily collateralized with proven producing oil and gas reserves based on a technical evaluation of these reserves. At December 31, 2024 and 2023, there were approximately $707,901 and $621,883 of energy-related loans outstanding, respectively.

The Company had a mortgage warehouse purchase program providing mortgage inventory financing for residential mortgage loans originated by mortgage banker clients across a broad geographic scale. Proceeds from the sale of mortgages were the primary source of repayment for warehouse inventory financing via approved investor takeout commitments. These loans typically had a very short duration ranging between a few days to 15 days. In some cases, loans to larger mortgage originators were financed for up to 60 days. Mortgage warehouse purchase program loans were collectively evaluated for impairment and were purchased under several contractual requirements which provided safeguards to the Company. The Company did not experience any losses on these loans and no allowance for credit losses were allocated to them. The mortgage warehouse purchase program line of business was discontinued in fourth quarter 2024 and there were no such loans outstanding as of December 31, 2024.

Commercial real estate loans are subject to underwriting standards and processes similar to commercial loans. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally largely dependent on the successful operation of the property or the business conducted on the property securing the loan. Commercial real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. The properties securing the Company’s commercial real estate portfolio are diverse in terms of type and geographic location as well as granularity with moderate average loan sizes. Management monitors the diversification of the portfolio on a quarterly basis by type and geographic location. Management also tracks the level of owner-occupied property versus non owner-occupied property. At both December 31, 2024 and 2023, the portfolio consisted of approximately 21% of owner-occupied property.

Land and commercial land development loans are underwritten using feasibility studies, independent appraisal reviews and financial analysis of the developers or property owners. Generally, borrowers must have a proven track record of success. Commercial construction loans are generally based upon estimates of cost and value of the completed project. These estimates may not be accurate. Commercial construction loans often involve the disbursement of substantial funds with the repayment dependent on the success of the ultimate project. Sources of repayment for these loans may be pre-committed permanent financing or sale of the developed property. The loans in this portfolio are geographically diverse and due to the increased risk are monitored closely by management and the board of directors on a quarterly basis.

Residential real estate and single-family interim construction loans are underwritten primarily based on borrowers’ documented income and ability to repay the Bank and other creditors as well as minimum collateral values and credit scores. Relatively small loan amounts are spread across many individual borrowers, which minimizes risk in the residential portfolio. In addition, management evaluates trends in past dues and current economic factors on a regular basis. 27

Agricultural loans are collateralized by real estate and/or agricultural-related assets. Agricultural real estate loans are primarily comprised of loans for the purchase of farmland. Loan-to-value ratios on loans secured by farmland generally do not exceed 80% and have amortization periods limited to twenty years. Agricultural non-real estate loans are generally comprised of term loans to fund the purchase of equipment, livestock and seasonal operating lines to grain farmers to plant and harvest corn and soybeans. Specific underwriting standards have been established for agricultural-related loans including the establishment of projections for each operating year based on industry developed estimates of farm input costs and expected commodity yields and prices. Operating lines are typically written for one year and secured by the crop and other farm assets as considered necessary. Agricultural loans carry credit risks as they involve larger balances concentrated with single borrowers or groups of related borrowers. In addition, repayment of such loans depends on the successful operation or management of the farm property securing the loan or for which an operating loan is utilized. Farming operations may be affected by adverse weather conditions such as drought, hail or floods that can severely limit crop yields.

Consumer loans represent less than 1% of the outstanding total loan portfolio. Collateral consists primarily of automobiles and other personal assets. Credit score analysis is used to supplement the underwriting process.

Most of the Company’s lending activity occurs within the state of Texas, primarily in the north, central and southeast Texas regions and the state of Colorado, specifically along the Front Range area. As of December 31, 2024, loans in the North Texas region represented 33% of the total portfolio, followed by the Colorado Front Range region at 28%, the Houston region at 26% and the Central Texas region at 13%. A large percentage of the Company’s portfolio consists of commercial and residential real estate loans. As of December 31, 2024 and 2023, there were no concentrations of loans related to a single industry in excess of 10% of total loans.

Under ASC 326, the allowance for credit losses is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected on the loans. Loans, or portions thereof, are charged-off against the allowance when they are deemed uncollectible. Recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. The amount of the allowance represents management's best estimate of current expected credit losses on loans considering available information relevant to assessing collectibility over the loans' contractual terms, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals and modifications unless the extension or renewal options are included in the borrower contract and are not unconditionally cancellable by the Company.

The Company's allowance balance is estimated using relevant available information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, credit quality, or term as well as for changes in environmental conditions, such as changes in unemployment rates, gross domestic product, property values, various price indices, and/or other relevant factors. The Company utilizes Moody’s Analytics economic forecast scenarios and assigns probability weighting to those scenarios which best reflect management’s views on the economic forecast. 28

The allowance for credit losses is measured on a collective basis for portfolios of loans when similar risk characteristics exist. Loans that do not share risk characteristics are evaluated for expected credit losses on an individual basis and excluded from the collective evaluation. For determining the appropriate allowance for credit losses on a collective basis, the loan portfolio is segmented into pools based upon similar risk characteristics and a lifetime loss-rate model is utilized. For modeling purposes, loan pools include: commercial and industrial, commercial real estate - construction/land development, commercial real estate - owner occupied, commercial real estate - non-owner occupied, agricultural, residential real estate, HELOCs, single-family interim construction, and consumer. Management periodically reassesses each pool to ensure the loans within the pool continue to share similar characteristics and risk profiles and to determine whether further segmentation is necessary. The measurement of expected credit losses is impacted by loan/borrower attributes and certain macroeconomic variables. Management has determined that they are reasonably able to forecast the macroeconomic variables used in the modeling processes with an acceptable degree of confidence for a total of two years then encompassing a reversion process whereby the forecasted macroeconomic variables are reverted to their historical mean utilizing a rational, systematic basis. Management qualitatively adjusts model results for risk factors that are not considered within the modeling processes but are nonetheless relevant in assessing the expected credit losses within the loan pools. These qualitative factor (Q-Factor) adjustments may increase or decrease management's estimate of expected credit losses by a calculated percentage or amount based upon the estimated level of risk.

Loans exhibiting unique risk characteristics and requiring an individual evaluation are measured based on 1) the present value of expected future cash flows discounted at the loan's effective interest rate; 2) the loan's observable market price; or 3) the fair value of collateral if the loan is collateral dependent. The majority of the Company’s individually evaluated loans are measured at the fair value of the collateral.

Management continually evaluates the allowance for credit losses based upon the factors noted above. Should any of the factors considered by management change, the Company’s estimate of credit losses could also change and would affect the level of future provision for credit losses. Portions of the allowance may be allocated for specific credits; however, the entire allowance is available for any credit that, in management’s judgment, should be charged-off. While the calculation of the allowance for credit losses utilizes management’s best judgment and all the information available, the adequacy of the allowance for credit losses is dependent on a variety of factors beyond the Company’s control, including, among other things, the performance of the entire loan portfolio, the economy, changes in interest rates and the view of regulatory authorities towards loan classifications.

Loans requiring an individual evaluation are generally identified at the servicing officer level based on review of weekly past due reports and/or the loan officer’s communication with borrowers. In addition, the status of past due loans are routinely discussed within each lending region as well as credit committee meetings to determine if classification is warranted. The Company’s internal loan review department has implemented an internal risk-based loan review process to identify potential internally classified loans that supplements the independent external loan review. Independent loan reviews cover a wide range of the loan portfolio, including large lending relationships, specifically targeted loan types, and if applicable recently acquired loan portfolios. These reviews include analysis of borrower’s financial condition, payment histories, review of loan documentation and collateral values to determine if a loan should be internally classified. Generally, once classified, an analysis is completed by the credit department to determine the amount of allocated allowance for credit loss required. Expected credit losses for collateral dependent loans, including loans where the borrower is experiencing financial difficulty but foreclosure is not probable, are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. 29

The Company will charge-off that portion of any loan which management considers a loss. Commercial and real estate loans are generally considered for charge-off when exposure beyond collateral coverage is apparent and when no further collection of the loss portion is anticipated based on the borrower’s financial condition.

The following table presents loans that were evaluated for expected credit losses on an individual basis and the related specific credit loss allocations, by loan class as of December 31, 2024 and 2023:

Total nonperforming loans $21,541 $26,578 $10 $3,591 $— $75 $5 $51,800

____________

^(1)^ There are $8,918 and $14 in loans on nonaccrual without an allowance for credit loss as of December 31, 2024 and 2023, respectively. Additionally, no interest income was recognized on nonaccrual loans. No significant amounts of accrued interest was reversed during the years ended December 31, 2024 and 2023.

The accrual of interest is discontinued on a loan when management believes that, after considering collection efforts and other factors, the borrower's financial condition is such that collection of interest is doubtful, as well as when required by regulatory provisions. Regulatory provisions would typically require the placement of a loan on non-accrual status if 1) principal or interest has been in default for a period of 90 days or more unless the loan is both well secured and in the process of collection or 2) full payment of principal and interest is not expected. All interest accrued but not collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income. Cash collections on nonaccrual loans are generally credited to the loan receivable balance, and no interest income is recognized on those loans until the principal balance has been collected. Loans are generally returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Occasionally, the Company modifies loans to borrowers in financial distress by providing certain concessions, such as principal forgiveness, term extension, an other-than-insignificant payment delay, an interest rate reduction, or a combination of such concessions. When principal forgiveness is provided, the amount of forgiveness is charged-off against the allowance for credit losses. Upon the Company's determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or portion of the loan) is written off. During the years ended December 31, 2024 and 2023, the Company did not provide any modifications under these circumstances to borrowers experiencing financial difficulty. 31

The Company’s internal classified report is segregated into the following categories: 1) Pass/Watch, 2) Special Mention, 3) Substandard, 4) Doubtful and 5) Loss. The loans placed in the Pass/Watch category reflect the Company’s opinion that the loans reflect potential weakness that requires monitoring on a more frequent basis. The loans in the Special Mention category reflect the Company’s opinion that the credit contains weaknesses which represent a greater degree of risk and warrant extra attention. These loans are reviewed monthly by officers and senior management to determine if a change in category is warranted. The loans placed in the Substandard category are considered to be potentially inadequately protected by the current debt service capacity of the borrower and/or the pledged collateral. These credits, even if apparently protected by collateral value, have shown weakness related to adverse financial, managerial, economic, market or political conditions, which may jeopardize repayment of principal and interest and may be considered impaired. There is a possibility that some future loss could be sustained by the Company if such weakness is not corrected. The Doubtful category includes loans that are in default or principal exposure is probable and the possibility of loss is extremely high. The Loss category includes loans that are considered uncollectible, with little chance of turnaround. 32

Management considers the guidance in ASC 310-20 when determining whether a modification, extension or renewal of a loan constitutes a current period origination. 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:

Note 7. Goodwill and Other Intangible Assets, Net

The following table presents the changes in the carrying amount of goodwill as of and for the years ended December 31, 2024 and 2023:

December 31,
2024 2023
Balance at beginning of year $994,021 $994,021
Goodwill impairment charge (518,000)
Balance at end of year $476,021 $994,021

During the first half of 2024, market volatility in the banking sector resulted in declines in the Company's stock price and market capitalization. Management believed such decrease was a triggering indicator requiring an interim goodwill impairment quantitative analysis for first quarter 2024. Based on an analysis performed, the Company's estimated fair value to a market participant as of March 31, 2024, exceeded its carrying amount resulting in no impairment charge for the period. In connection with the announcement of the merger with and into SSB as described in Note 1. Summary of Significant Accounting Policies, the Company entered into a definitive agreement on May 17, 2024 whereby the implied consideration of the merger transaction was less than the Company's book value. This triggered the Company to perform an interim goodwill impairment assessment which determined the estimated fair value of the single reporting unit was equal to the implied valuation of the merger transaction based upon the conversion ratio to SSB’s stock price as of the measurement date. As such, the Company recorded $518,000 in goodwill impairment charges during second quarter 2024 as the estimated fair value of equity was less than its book value. This was a non-cash charge to earnings and had no impact on the Company's regulatory capital ratios, cash flows, or liquidity position. Market conditions in the industry during the second half of the year stabilized and stock values for both SSB and the Company increased resulting in the Company's implied value, as noted above, exceeding its book value through December 31, 2024.

The following is a summary of other intangible assets:

December 31,
2024 2023
Gross core deposit intangible $125,884 $125,884

Total core deposit intangible, net $35,358 $46,617
Gross customer relationship intangible $6,407 $6,407
Less accumulated amortization (2,957) (2,464)
Total customer relationship intangible, net $3,450 $3,943
Total other intangible assets, net $38,808 $50,560

Amortization expense related to intangible assets amounted to $11,752, $12,439 and $12,491 for the years ended December 31, 2024, 2023 and 2022, respectively. The remaining weighted average amortization period for intangible assets is 3.9 years as of December 31, 2024. 38

Note 11. Junior Subordinated Debentures

The Company has formed or acquired nine statutory business trusts (the Trusts) for the purpose of issuing trust preferred securities. Each of the Trusts have issued capital and common securities and invested the proceeds thereof in an equivalent amount of junior subordinated debentures (the Debentures) issued by the Company. The interest rate payable on, and the payment terms of the Debentures are the same as the distribution rate and payment terms of the respective issues of capital and common securities issued by the Trusts. The Debentures are subordinated and junior in right of payment to all present and future senior indebtedness. The Company has fully and unconditionally guaranteed the obligations of each of the Trusts with respect to the capital and common securities. Except under certain circumstances, the common securities issued to the Company by the trusts possess sole voting rights with respect to matters involving those entities. Under certain circumstances, the Company may, from time to time, defer the debentures' interest payments, which would result in a deferral of distribution payments on the related trust preferred securities and, with certain exceptions, prevent the Company from declaring or paying cash distributions on the Company's common stock and any other future debt ranking equally with or junior to the debentures. The Company may redeem the debentures, which are intended to qualify as Tier 1 capital, at the Company’s option, subject to approval of the Federal Reserve. 41

Note 13. Off-Balance Sheet Arrangements, Commitments and Contingencies

Financial Instruments with Off-Balance Sheet Risk

The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. The commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the balance sheet.

The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of this instrument. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments.

At December 31, 2024 and 2023, the approximate amounts of these financial instruments were as follows:

December 31,
2024 2023
Commitments to extend credit $2,975,366 $3,107,827
Standby letters of credit 29,207 31,627
$3,004,573 $3,139,454

43

(Dollars in thousands, except for share and per share information)

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 drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained if deemed necessary by the Company upon extension of credit is based on management’s credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, farm crops, property, plant and equipment and income-producing commercial properties.

Letters of credit are written conditional commitments used by the Company to guarantee the performance of a customer to a third party. The Company’s policies generally require that letter of credit arrangements contain security and debt covenants similar to those contained in loan arrangements. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount shown in the table above. If the commitment is funded, the Company would be entitled to seek recovery from the customer.

Allowance For Credit Losses on Off-Balance Sheet Credit Exposures

The allowance for credit losses on off-balance sheet credit exposures is calculated under ASC 326, representing expected credit losses over the contractual period for which the Company is exposed to credit risk resulting from a contractual obligation to extend credit. Off-balance sheet credit exposures primarily consist of amounts available under outstanding lines of credit and letters of credit detailed in the table above. The allowance for credit losses on off-balance sheet credit exposures is estimated by loan segment at each balance sheet date using the same methodologies as portfolio loans, taking into consideration the likelihood that funding will occur based on historical utilization rates. The allowance is included in other liabilities on the Company’s consolidated balance sheet.

The allowance for credit losses on off-balance sheet commitments was as follows:

December 31,
2024 2023 2022
Balance at beginning of period $3,897 $3,944 $4,722
Provision for off-balance sheet credit exposure (980) (47) (778)
Balance at end of period $2,917 $3,897 $3,944

Litigation

The Bank was a party to a legal proceeding inherited in connection with its acquisition of BOH Holdings, Inc. and its subsidiary, Bank of Houston (BOH). On February 27, 2023, the Bank entered into a settlement in principle with the plaintiffs and executed a settlement agreement on March 7, 2023. The settlement and bar orders were approved by the Court on August 8, 2023. On June 24, 2024, the Bank made a one-time cash payment of $100,000 to the court appointed receiver in full settlement of the litigation. Such settlement was recognized in 2023 as litigation settlement expense included in noninterest expense on the accompanying statements of income (loss) along with $2,500 in related legal and other fees. The Bank now considers this matter fully resolved.

In addition, the Company is involved in other legal actions arising from normal business activities, as well as lawsuits related to the pending merger with SSB. Management believes that the outcome of such proceedings will not materially affect the financial position, results of operations or cash flows of the Company. 44

Note 17. Fair Value Measurements

The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below.

Investment securities available for sale

Securities classified as available for sale are reported at fair value utilizing Level 1 and Level 2 inputs. Securities are classified within Level 1 when quoted market prices are available in an active market. Inputs include securities that have quoted prices in active markets for identical assets. For securities utilizing Level 2 inputs, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury and other yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other things.

Loans held for sale

Certain mortgage loans held for sale are measured at fair value on a recurring basis due to the Company's election to adopt fair value accounting treatment for those loans originated for which the Company has entered into certain derivative financial instruments as part of its mortgage banking and related risk management activities. These instruments include interest rate lock commitments and mandatory forward commitments to sell these loans to investors known as forward mortgage-backed securities trades. This election allows for a more effective offset of the changes in fair values of the assets and the mortgage related derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC 815, Derivatives and Hedging. Mortgage loans held for sale, for which the fair value option was elected, which are sold on a servicing released basis, are valued using a market approach by utilizing either: (i) the fair value of securities backed by similar mortgage loans, adjusted for certain factors to approximate the fair value of a whole mortgage loan, including the value attributable to mortgage servicing and credit risk, (ii) current commitments to purchase loans or (iii) recent observable market trades for similar loans, adjusted to credit risk and other individual loan characteristics. As these prices are derived from market observable inputs, the Company classifies these valuations as Level 2 in the fair value disclosures. For mortgage loans held for sale for which the fair value option was elected, the earned current contractual interest payment is recognized in interest income, loan origination costs and fees on fair value option loans are recognized in earnings as incurred and not deferred. The Company has no continuing involvement in any residential mortgage loans sold.

Derivatives

The Company utilizes interest rate swaps to hedge exposure to interest rate risk and variability of cash flows associated to changes in the underlying interest rate of the hedged item. These hedging interest rate swaps are classified as a cash flow hedge. The Company utilizes a third-party vendor for derivative valuation purposes. These vendors determine the appropriate fair value based on a net present value calculation of the cash flows related to the interest rate swaps using primarily observable market inputs such as interest rate yield curves (Level 2 inputs).

The estimated fair values of interest rate lock commitments utilize current secondary market prices for underlying loans and estimated servicing value with similar coupons, maturity and credit quality, subject to the anticipated loan funding probability (pull-through rate). The fair value of interest rate lock commitments is subject to change primarily due to changes in interest rates and the estimated pull-through rate. These commitments are classified as Level 2 in the fair value disclosures, as the valuations are based on observable market inputs. 50

(Dollars in thousands, except for share and per share information)

Forward mortgage-backed securities trades are exchange-traded or traded within highly active dealer markets. In order to determine the fair value of these instruments, the Company utilized the exchange price or dealer market price for the particular derivative contract; therefore these contracts are classified as Level 2. The estimated fair values are subject to change primarily due to changes in interest rates.

The Company also enters into certain interest rate derivative positions. The estimated fair value of these commercial loan interest rate swaps are obtained from a pricing service that provides the swaps' unwind value (Level 2 inputs). See Note 18. Derivative Financial Instruments, for more information.

Assets and Liabilities Measured on a Nonrecurring Basis

In accordance with ASC Topic 820, certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the assets and liabilities are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). The following table presents the assets carried on the consolidated balance sheet by caption and by level in the fair value hierarchy at December 31, 2024 and 2023, for which a nonrecurring change in fair value has been recorded:

Fair Value Measurements at Reporting Date Using
Assets<br><br>Measured<br><br>at Fair Value Quoted Prices<br><br>in Active<br><br>Markets for<br><br>Identical Assets<br><br>(Level 1) Significant<br><br>Other<br><br>Observable<br><br>Inputs<br><br>(Level 2) Significant<br><br>Unobservable<br><br>Inputs (Level 3) Period Ended<br><br>Total Losses
December 31, 2024
Assets:
Individually evaluated loans $8,843 $— $— $8,843 $4,476
December 31, 2023
Assets:
Individually evaluated loans $5,822 $— $— $5,822 $3,525
Other real estate owned 9,490 9,490 6,052

Individually evaluated loans are measured at an observable market price (if available) or at the fair value of the loan’s underlying collateral (if collateral dependent). Fair value of the loan’s collateral is determined by appraisals or independent valuation, which is then adjusted for the estimated costs related to liquidation of the collateral. Management’s ongoing review of appraisal information may result in additional discounts or adjustments to valuation based upon more recent market sales activity or more current appraisal information derived from properties of similar type and/or locale. In addition, management's discounting criteria may vary for loans secured by non-real estate collateral such as inventory, oil and gas reserves, accounts receivable, equipment or other business assets. Management reviews the appraisals or valuations for appropriateness and adjusts the value downward to consider selling and closing costs, which typically range from 5% to 8% of the appraised value. Therefore, the Company has categorized its individually evaluated loans as Level 3. 51

(Dollars in thousands, except for share and per share information)

Other real estate owned is measured at fair value on a nonrecurring basis (upon initial recognition or subsequent impairment). Other real estate owned is classified within Level 3 of the valuation hierarchy. When transferred from the loan portfolio, other real estate owned is adjusted to fair value less estimated selling costs and is subsequently carried at the lower of carrying value or fair value less estimated selling costs. The fair value is determined using an external appraisal process, discounted based on internal criteria. Management reviews the external appraisals for appropriateness and adjusts the value downward to consider selling and closing costs, which typically range from 5% to 8% of the appraised value. Therefore, the Company has categorized its other real estate as Level 3. There was no other real estate owned remeasured during the year ended December 31, 2024.

In addition, mortgage loans held for sale not recorded under the fair value option are required to be measured at the lower of cost or fair value. The fair value of these loans is based upon binding quotes or bids from third party investors. As of December 31, 2024 and 2023, all mortgage loans held for sale not recorded under the fair value option were recorded at cost. 52

(Dollars in thousands, except for share and per share information)

The methods and assumptions used by the Company in estimating fair values of financial instruments as disclosed herein in accordance with ASC Topic 825, Financial Instruments, other than for those measured at fair value on a recurring and nonrecurring basis discussed above, are as follows:

Cash and cash equivalents: The carrying amounts of cash and cash equivalents approximate their fair value.

Certificates of deposit held in other banks: The fair value of certificates of deposit held in other banks is based upon current market rates.

Investment securities held to maturity: For investment securities held to maturity, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury and other yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security's terms and conditions, among other things.

Loans held for sale, at cost: The fair value of loans held for sale is determined based upon commitments on hand from investors.

Loans: A discounted cash flow model is used to estimate the fair value of the loans. The discounted cash flow approach models the credit losses directly in the projected cash flows, applying various assumptions regarding credit, interest and prepayment risks for the loans based on loan types, payment types and fixed or variable classifications.

Federal Home Loan Bank of Dallas and other restricted stock: The carrying value of restricted securities such as stock in the Federal Home Loan Bank of Dallas and Independent Bankers Financial Corporation approximates fair value.

Deposits: The fair values disclosed for demand deposits are, by definition, equal to the amount payable on demand at the reporting date (that is their carrying amounts). The carrying amounts of variable-rate certificates of deposit (CDs) approximate their fair values at the reporting date. Fair values for fixed-rate CDs are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.

Federal Home Loan Bank advances, line of credit and federal funds purchased: The fair value of advances maturing within 90 days approximates carrying value. Fair value of other advances is based on the Company’s current borrowing rate for similar arrangements.

Other borrowings: The estimated fair value approximates carrying value for short-term borrowings. The fair value of private subordinated debentures are based upon prevailing rates on similar debt in the market place. The subordinated debentures that are publicly traded are valued based on indicative bid prices based upon market pricing observations in the current market.

Junior subordinated debentures: The fair value of junior subordinated debentures is estimated using discounted cash flow analyses based on the published Bloomberg US Financials BB rated corporate bond index yield.

Accrued interest: The carrying amounts of accrued interest approximate their fair values.

Off-balance sheet instruments: Fair values for off-balance sheet, credit-related 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 fair value of commitments is not material.

Note 18. Derivative Financial Instruments

The Company accounts for its derivative financial instruments in accordance with ASC Topic 815 which requires all derivative instruments to be carried at fair value on the balance sheet. The Company has designated certain derivative instruments used to manage interest rate risk as hedge relationships with certain assets, liabilities or cash flows being hedged. Certain derivatives used for interest rate risk management are not designated in a hedge relationship and are used for asset and liability management related to the Company's mortgage banking activities and commercial customers' financing needs. All derivatives are carried at fair value in either other assets or other liabilities.

Derivative instruments designated in a hedge relationship to mitigate exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivative instruments designated in a hedge relationship to mitigate exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges.

The Company formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions at the inception of the hedge relationship. This documentation includes linking the fair value for cash flow hedges to the specific assets and liabilities on the balance sheet or the specific firm commitments or forecasted transaction. The Company assesses, both at the hedge's inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended.

The Company's objectives in using interest rate derivatives are to add stability to interest income and to manage its exposure to interest rate movements. To accomplish this objective, the Company uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of fixed-rate amounts from a counterparty in exchange for the Company making variable-rate payments over the life of the agreements without exchange of the underlying notional amount. The Company had two interest rate swap derivatives with an aggregated notional amount of $100,000 that were designated as cash flow hedges. The derivatives were intended to hedge the variable cash flows associated with certain existing variable-interest rate loans and were determined to be effective during the year ended December 31, 2024. During December 2024, both cash flow hedges with an aggregate liability fair value of $6,735 were terminated. As of December 31, 2024, the total unrealized losses on the terminated cash flow hedges remaining in accumulated other comprehensive income (loss) is $5,224, net of tax. The unrealized losses will be reclassified into interest income as the underlying transactions impact earnings through the original maturity of the hedged transactions. The total remaining term over which the unrealized losses will be reclassified into earnings is approximately three and one-half years.

For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in accumulated other comprehensive income (loss) and subsequently reclassified into interest income in the same period that the hedged transaction affects earnings. Amounts of losses recognized in accumulated other comprehensive income (loss) related to derivatives was $2,156, net of tax, and the amounts of losses that were reclassified to interest income as interest payments were made on the Company’s variable-rate loans was $3,403, net of tax, during and for the year ended December 31, 2024. Amounts of losses recognized in accumulated other comprehensive income related to derivatives was $917, net of tax, and the amounts of losses that were reclassified to interest income as interest payments were received on the Company’s variable-rate loans was $3,293, net of tax, during and for the year ended December 31, 2023. During the next twelve months, the Company estimates that $2,990 will be reclassified as a decrease to interest income. 55

Through its mortgage banking division, the Company enters into interest rate lock commitments with consumers to originate mortgage loans at a specified interest rate. These commitments, which contain fixed expiration dates, offer the borrower an interest rate guarantee provided the loan meets underwriting guidelines and closes within the timeframe established by the Company. The Company manages the changes in fair value associated with changes in interest rates related to interest rate lock commitments by using forward sold commitments known as forward mortgage-backed securities trades. These instruments are typically entered into at the time the interest rate lock commitment is made.

The Company offers certain derivatives products, primarily interest rate swaps, directly to qualified commercial banking customers to facilitate their risk management strategies. The interest rate swap derivative positions relate to transactions in which the Company enters into an interest rate swap with a customer, while at the same time entering into an offsetting interest rate swap with another financial institution. An interest rate swap transaction allows customers to effectively convert a variable rate loan to a fixed rate. In connection with each swap, the Company agrees to pay interest 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 agrees to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount.

The following table provides the outstanding notional balances and fair values of outstanding derivative positions at December 31, 2024 and 2023:

The credit exposure related to interest rate swaps is limited to the net favorable value of all swaps by each counterparty, which was approximately $6,504 and $9,699 at December 31, 2024 and 2023, respectively. In some cases collateral may be required from the counterparties involved if the net value of the derivative instruments exceeds a nominal amount. Collateral levels are monitored and adjusted on a regular basis for changes in interest rate swap values. At December 31, 2024 and 2023, cash of $10,159 and $10,242 and securities of $0 and $444 were pledged as collateral for these derivatives, respectively. Additionally, counterparties had deposited $1,200 and $2,130 of cash with the Company at December 31, 2024 and 2023, respectively.

The Company has entered into credit risk participation agreements with financial institution counterparties for interest rate swaps related to loans in which the Company is either a participant or a lead bank. Risk participation agreements entered into as a participant bank provide credit protection to the financial institution counterparty should the borrower fail to perform on its interest rate derivative contract with that financial institution. The Company is party to one risk participation agreement as a participant bank having a notional amount of $5,818 and $1,481 at December 31, 2024 and December 31, 2023, respectively. Risk participation agreements entered into as the lead bank provide credit protection to the Company should the borrower fail to perform on its interest rate derivative contract. The Company is party to zero and one risk participation agreement as the lead bank having a notional amount of $0 and $8,805 at December 31, 2024 and 2023, respectively.

The changes in the fair value of interest rate lock commitments and the forward sales of mortgage-backed securities are recorded in mortgage banking revenue. These gains and losses were not attributable to instrument-specific credit risk. For commercial interest rate swaps, because the Company acts as an intermediary for our customer, changes in the fair value of the underlying derivative contracts substantially offset each other and do not have a material impact on the results of operations.

A summary of derivative activity and the related impact on the consolidated statements of income for the years ended December 31, 2024, 2023 and 2022 is as follows:

Note 19. Stock Awards

The Company grants common stock awards to certain employees of the Company. In May 2022, the shareholders of the Company approved the 2022 Equity Incentive Plan (2022 Plan). Under this plan, the Compensation Committee may grant awards to certain employees and directors of the Company in the form of restricted stock, restricted stock units, stock appreciation rights, qualified and nonqualified stock options, performance share awards and other equity-based awards. Effective with the adoption of the 2022 Plan, no further awards will be granted under the prior 2013 Equity Incentive Plan (2013 Plan).

Shares issued under these plans are restricted stock and performance stock awards. Restricted stock awarded generally vest evenly over the required employment period, and range from one to four years. Performance stock units awarded have a three to four year cliff vesting period. Restricted stock awards granted are issued at the date of grant and receive dividends. Performance stock units are eligible to receive dividend equivalents as such dividends are declared on the Company's common stock during the performance period. Equivalent dividend payments are based upon the number of shares issued under each performance award and are deferred until such time that the units vest and the shares are issued.

Restricted Stock Awards

The following table summarizes the activity in nonvested restricted stock awards for the years ended December 31, 2024 and 2023:

​<br><br>​ ​<br><br>​<br><br>​

Forfeited during the period (5,940) 63.07
Nonvested shares, December 31, 2023 285,340 $58.99

Compensation expense related to these awards is recorded based on the fair value of the award at the date of grant and totaled $8,433, $8,258 and $10,856 for the years ended December 31, 2024, 2023 and 2022, respectively. Compensation expense is recorded in salaries and employee benefits in the accompanying consolidated statements of income. At December 31, 2024, future compensation expense is estimated to be $7,942 and will be recognized over a remaining weighted average period of 1.64 years.

The fair value of common stock awards that vested during the years ended December 31, 2024, 2023 and 2022 was $7,939, $7,971 and $13,795, respectively. The Company has recorded $275, $280 and $(703) in excess tax expense (benefit) on vested restricted stock to income tax expense for the years ended December 31, 2024, 2023 and 2022, respectively.

In connection with the SSB merger as discussed in Note 1. Summary of Significant Accounting Policies, and the subsequent closing of such merger as discussed in Note 23. Subsequent Event, all outstanding restricted stock awards immediately vested upon the change-in-control at the effective time of merger in accordance with the 2013 Plan, 2022 Plan, and the definitive agreement.

Performance-Based Restricted Stock Units

Performance-based restricted stock units (PSUs) represent shares potentially issuable in the future. For awards granted prior to 2024, the number of shares issued is based upon the measure of the Company's achievement of its relative adjusted return on average tangible common equity, as defined by the Company, over the award's performance period as compared to an identified peer group's achievement over the same performance period. For awards granted in 2024, the number of shares issued is based upon two equally weighted measures 1) the Company's cumulative adjusted diluted earnings per share over the performance period, as defined by the Company, and 2) its relative total shareholder return over the award's performance period as compared to an identified peer group. The number of shares issuable under each performance award is the product of the award target and the award payout percentage for the given level of achievement which ranges from 0% to 150% of the target.

The following table summarizes the activity in nonvested PSUs at target award level for the years ended December 31, 2024 and 2023:

​<br><br>​ ​<br><br>​<br><br>​
Performance-Based Restricted Stock Units Number of<br><br>Shares Weighted Average<br><br>Grant Date<br><br>Fair Value
Nonvested shares, December 31, 2023 178,178 $51.55
Granted during the period 37,738 44.69
Vested during the period (110,539) 41.79
Forfeited during the period (20,198) 62.58
Nonvested shares, December 31, 2024 85,179 $58.55
Nonvested shares, December 31, 2022 140,240 $49.20
Granted during the period 37,938 60.21
Nonvested shares, December 31, 2023 178,178 $51.55

Compensation expense related to PSUs is estimated each period based on the fair value of the target stock unit at the grant date and the most probable level of achievement of the performance condition, adjusted for the passage of time within the vesting periods of the awards. Compensation expense related to these awards was $2,865, $(764) and $2,841 for the years ended December 31, 2024, 2023 and 2022, respectively. As of December 31, 2024, the unrecognized compensation expense is estimated to be $934. The remaining performance period over which the expense will be recognized is 2.14 years.

The fair value of common stock awards that vested during the year ended December 31, 2024 was $6,274.

In connection with the SSB merger as discussed in Note 1. Summary of Significant Accounting Policies, and the subsequent closing of such merger as discussed in Note 23. Subsequent Event, all outstanding PSU awards were immediately issuable at target performance and vested upon the change-in-control at the effective time of merger in accordance with the 2013 Plan, 2022 Plan, and the definitive agreement.

Note 20. Regulatory Matters

Under banking law, there are legal restrictions limiting the amount of dividends the Bank can declare. Approval of the regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of the Bank to fall below specified minimum levels. For state banks, subject to regulatory capital requirements, payment of dividends is generally allowed to the extent of net profits.

The Company (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Tier 2 capital for the Company includes permissible portions of the Company's subordinated notes. The permissible portion of qualified subordinated notes decreases 20% per year during the final five years of the term of the notes.

The Company is subject to the Basel III regulatory capital framework (the Basel III Capital Rules). The Basel III Capital Rules require that the Company maintain a 2.5% capital conservation buffer above the minimum risk-based capital adequacy requirements. The capital conservation buffer is designed to absorb losses during periods of economic stress and requires increased capital levels for the purpose of capital distributions and other payments. Failure to meet the full amount of the buffer will result in restrictions on the Company's ability to make capital distributions, including dividend payments and stock repurchases and to pay discretionary bonuses to executive officers.

In connection with the adoption of ASC 326, the Company elected to adopt the permissible three year transition option to phase in the day one effects to capital. The deferral has been applied to capital ratios presented below through December 31, 2023.

Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) of total, Common Equity Tier 1 (CET1) and Tier 1 capital (as defined in the regulations) to risk weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined). Management believes, as of December 31, 2024 and 2023, the Company and the Bank meet all capital adequacy requirements to which they are subject, including the capital buffer requirement.

As of December 31, 2024 and 2023, the Bank’s capital ratios exceeded those levels necessary to be categorized as “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well capitalized,” the Bank must maintain minimum total risk based, CET1, Tier 1 risk based and Tier 1 leverage ratios as set forth in the table. There are no conditions or events that management believes have changed the Bank’s category. 60

However, the Federal Reserve Board and the FDIC may require the Company to maintain a Tier 1 to Average Assets Ratio above the required minimum.

Stock repurchase program: From time to time, the Company's Board of Directors has authorized stock repurchase programs which allow the Company to purchase its common stock generally over a one-year period at various prices in the open market or in privately negotiated transactions. The Company did not have an active stock repurchase program in 2024. There were no shares repurchased under the prior 2023 Plan during the twelve months ended December 31, 2023.

Company stock repurchased to settle employee tax withholding related to vesting of stock awards totaled 70,482 shares at a total cost of $3,674, and 41,727 shares at a total cost of $2,175 for the periods ended December 31, 2024 and 2023, respectively, and were not included under the repurchase program. 61

The unaudited pro forma condensed combined financial statements are presented for illustrative purposes only and do not purport to represent the surviving company’s consolidated results of operations or consolidated financial position that would actually have occurred had the merger been consummated on the dates assumed or to project the surviving company’s consolidated results of operations or consolidated financial position for any future date or period.

The preparation of the unaudited pro forma condensed combined financial statements and related adjustments required management to make certain assumptions and estimates. The unaudited pro forma condensed combined financial data appearing below also does not consider any potential effects of changes in market conditions on revenues or expense efficiencies, among other factors. In addition, as explained in more detail in the accompanying notes, the preliminary allocation of the pro forma purchase price reflected in the unaudited pro forma condensed combined financial data is subject to adjustment and may vary significantly from the actual purchase price allocation that will be recorded upon completion of the merger.

NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

Note 1: Basis of pro forma presentation

The accompanying unaudited pro forma combined condensed financial statements and related notes were prepared in accordance with Article 11 of Regulation S-X. The unaudited pro forma combined condensed statement of income for the year ended December 31, 2024 combines the historical consolidated statements of income of SouthState and Independent, giving effect to the merger as if it had been completed on January 1, 2024 and includes adjustments for the reversal of transaction costs associated with the merger. The accompanying unaudited pro forma combined condensed balance sheets as of December 31, 2024 combines the historical consolidated balance sheets of SouthState and Independent, giving effect to the merger as if it had been completed on December 31, 2024.

SouthState's and Independent's historical financial statements were prepared in accordance with GAAP. As discussed in Note 3 and Note 4, certain reclassifications were made to align SouthState's and Independent's financial statement presentation. SouthState has not identified all adjustments necessary to conform Independent's accounting policies to SouthState's accounting policies. The combined company is performing a more detailed review of Independent’s accounting policies. As a result of that review, differences could be identified between the accounting policies of the two companies that, when combined, could have a material impact on the combined company’s financial information.

The accompanying unaudited pro forma combined condensed financial statements and related notes were prepared using the acquisition method of accounting under the provisions of ASC 805, with SouthState as the acquirer of Independent. ASC 805 requires, among other things, that the assets acquired and liabilities assumed in a business combination be recognized at their fair values as of the acquisition date. For purposes of the unaudited pro forma combined condensed balance sheets, the purchase consideration has been allocated to the assets acquired and liabilities assumed of Independent based upon management’s preliminary estimate of their fair values as of December 31, 2024. SouthState has not completed the valuation analysis and calculations in sufficient detail necessary to arrive at the required estimates of the fair value of Independent assets to be acquired or liabilities assumed, other than a preliminary estimate for intangible assets and certain financial assets and financial liabilities. Accordingly, apart from the aforementioned, certain Independent assets and liabilities are presented at their respective carrying amounts and should be treated as preliminary values. Any differences between the fair value of the consideration transferred and the fair value of the assets acquired and liabilities assumed will be recorded as goodwill. Accordingly, the purchase price allocation and related adjustments reflected in these unaudited pro forma combined condensed financial statements are preliminary and subject to revision based on final determination of fair value.

All dollar amounts presented within these NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS are in thousands of dollars, except share data, unless otherwise indicated.

Note 2: Preliminary purchase price allocation

Under the terms of the merger agreement, holders of Independent common stock have the right to receive a fixed exchange ratio of 0.60 shares of SouthState common stock for each share of Independent common stock. For purposes of the unaudited pro forma combined condensed balance sheet, the merger consideration is based on the total number of shares of Independent common stock issued and outstanding as of December 31, 2024 and the closing price per share of SouthState common stock of $99.48 on December 31, 2024, including Independent's outstanding restricted stock awards and performance-based restricted stock units as of December 31, 2024 that vested and converted to SouthState common stock pursuant to the terms of the merger agreement.

The following table summarizes the preliminary purchase price allocation to the estimated fair value of assets and liabilities of Independent (in thousands, except share data):

Independent common shares outstanding as of December 31, 2024 41,444,598
Independent performance stock units outstanding and vesting on December 31, 2024 85,179
Less shares withheld for tax withholding due on vesting of stock awards (96,691)
Independent common shares outstanding, less net tax withholding, as of December 31, 2024 41,433,086
Exchange ratio 0.60
SouthState common shares issuable 24,859,852
Less fractional shares (1,128)
SouthState common shares issued 24,858,724
Purchase price per share of the Company's common stock at December 31, 2024 $99.4800
Total purchase price from common stock $ 2,472,946
Cash in lieu for fractional shares 114
Total pro forma purchase price $ 2,473,060

The merger consideration as shown in the table above is allocated to the tangible and intangible assets acquired and liabilities assumed of Independent based on their preliminary estimated fair values. As mentioned above in Note 1, SouthState has not completed the valuation analysis and calculations in sufficient detail necessary to arrive at the required estimates of the fair market value of the Independent assets to be acquired or liabilities assumed, other than a preliminary estimate for intangible assets and certain financial assets and financial liabilities. Accordingly, apart from the aforementioned, certain assets acquired and liabilities assumed are presented at their respective carrying amounts and should be treated as preliminary values. The fair value assessments are preliminary and are based upon available information and certain assumptions, which SouthState believes are reasonable under the circumstances. Actual results may differ materially from the assumptions within the unaudited pro forma combined condensed financial statements.
