| Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block] | ITEM 1C. CYBERSECURITY Trustmark recognizes the critical importance of identifying, assessing and managing material risks from cybersecurity threats. Trustmark is committed to implementing and maintaining a comprehensive information security program to manage such risks and safeguard its systems and data. Trustmark’s Board of Directors has ultimate oversight of cybersecurity-related risks and it is assisted in this role by the Enterprise Risk Committee and the Audit Committee. Processes for identifying, assessing and managing cybersecurity-related risks are integrated into Trustmark’s overall enterprise risk management process, which is overseen by the Enterprise Risk Committee. The Enterprise Risk Committee is responsible for monitoring risks that are being taken by Trustmark, understanding the enterprise-wide effect of those risks and reporting such risks to the Board. In fulfilling this role, the Enterprise Risk Committee has primary oversight responsibility over management’s efforts to manage and mitigate cybersecurity-related risk and reviews and approves Trustmark’s cybersecurity strategy for protecting Trustmark’s information assets and technology platforms. The Audit Committee oversees Trustmark’s Internal Audit Department, which conducts reviews and assessments related to information security. Management provides periodic reports to the Enterprise Risk Committee and the Audit Committee, both of which provide reports of their meetings to the full Board. These reports to the Board and its Committees address the threat environment, vulnerability assessments, specific cyber incidents and management’s efforts to monitor, detect and prevent cyber threats. Trustmark’s information security program is primarily administered at the management level by the Information Security Department, which is led by Trustmark’s Chief Information Security Officer (CISO), and is supported by the Information Technology Department, which is led by Trustmark’s Chief Information Officer (CIO). The CISO reports to the CIO, who in turn reports to Trustmark’s Chief Credit and Operations Officer. Trustmark’s Information Security Department is responsible for day-to-day management of Trustmark’s information security program, including data loss prevention, access control, threat monitoring, incident response, insider threat monitoring and employee education and training. The Information Security Department also maintains policies related to cybersecurity and data security that provide the required governance for the information security program. Additionally, Trustmark’s Information Technology Department maintains policies that govern technical aspects of Trustmark’s information security program. Each policy is reviewed and approved by the Enterprise Risk Committee at least every three years and is mapped to applicable regulatory guidance. The Cybersecurity Operations team within the Information Technology Department maintains and runs Trustmark’s security operations center and is responsible for cybersecurity event management and maintaining security tooling. Trustmark also maintains an Information Security / Cybersecurity Management Committee, which is comprised of representatives from the Information Security, Information Technology, Enterprise Risk, Corporate Security, Internal Audit and Legal departments and members of executive management. This committee meets quarterly to discuss and review Trustmark’s information security program and receives qualitative and quantitative update reports from the Information Security Department, Internal Audit Department and Information Technology Department. Trustmark engages third party assessors, consultants and auditors in connection with its information security program, including to conduct external penetration testing, independent audits and risk assessments. Trustmark also utilizes third party service providers in the ordinary course of business. The Information Security Department performs information security assessments for third party service providers that store or process Trustmark confidential data. These information security assessments include a review of any systems and organization control reports, proof of the vendor’s independent testing of their data protection controls, as well as a review of any exceptions noted and assessment of management responses, results of vulnerability and penetration testing, incident response processes and third party data protection controls (which can include, but is not limited to: access reviews and controls, backups, monitoring, encryption standards and disaster recovery). The review of these areas is taken into account in order to provide an overall information security conclusion and risk rating for the vendor. As a regulated financial institution, Trustmark is also subject to financial privacy laws and its cybersecurity practices are subject to oversight by the federal banking agencies. For additional information, see “Supervision and Regulation – Financial Privacy Laws and Cybersecurity” included in Part I. Item 1 – Business of this report. Although Trustmark has not, as of the date of this Annual Report on Form 10-K, experienced a cybersecurity threat or incident that materially affected its business strategy, results of operations or financial condition, there can be no guarantee that Trustmark will not experience such an incident in the future. For additional information regarding the risk Trustmark faces from cybersecurity threats, please see the risk factors titled “Trustmark may experience disruptions of its operating systems or breaches in its information system security” and “Trustmark must utilize new technologies to deliver its products and services, which could require significant resources and expose Trustmark to additional risks, including cyber-security risks” included in Part I.

The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (GAAP). The preparation of financial statements in conformity with these accounting principles requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and income and expense during the reporting periods and the related disclosures. Although Management’s estimates contemplate current conditions and how they are expected to change in the future, it is reasonably possible that in 2025 actual conditions could vary from those anticipated, which could affect Trustmark’s financial condition and results of operations. Actual results could differ from those estimates. Securities Securities are classified as either held to maturity or available for sale. Securities are classified as held to maturity and carried at amortized cost when Management has the positive intent and the ability to hold them until maturity. Securities to be held for indefinite periods of time are classified as available for sale and carried at fair value, with the unrealized holding gains and losses reported as a component of other comprehensive income (loss), net of tax. Securities available for sale are used as part of Trustmark’s interest rate risk management strategy and may be sold in response to changes in interest rates, changes in prepayment rates and other factors. Management determines the appropriate classification of securities at the time of purchase. The amortized cost of debt securities classified as securities held to maturity or securities available for sale is adjusted for amortization of premiums and accretion of discounts to maturity of the security using the interest method. Such amortization or accretion is included in interest on securities. Realized gains and losses are determined using the specific identification method and are included in noninterest income as securities gains (losses), net. Securities transferred from the available for sale category to the held to maturity category are recorded at fair value at the date of transfer. Unrealized holding gains or losses associated with the transfer of securities from available for sale to held to maturity are included in the balance of accumulated other comprehensive income (loss), net of tax, in the consolidated balance sheets. These unrealized holding gains or losses are amortized over the remaining life of the security as a yield adjustment in a manner consistent with the amortization or accretion of the original purchase premium or discount on the associated security. Allowance for Credit Losses (ACL) Financial Accounting Standards Board (FASB) Accounting Standard Codification (ASC) Topic 326 requires a current expected credit losses methodology for estimating allowances for credit losses and applies to all financial instruments carried at amortized cost, including securities held to maturity, and makes targeted improvements to the accounting for credit losses on securities available for sale. Under FASB ASC Topic 326, the ACL is an estimate measured using relevant information about past events, including historical credit loss experience on financial assets with similar risk characteristics, current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the financial assets. Trustmark adopted a zero-credit loss assumption for certain classes of securities. This zero-credit loss assumption applies to debt issuances of the U.S. Treasury and agencies and instrumentalities of the United States government. The reasons behind the adoption of the zero-credit loss assumption were as follows: • High credit rating • Long history with no credit losses • Guaranteed by a sovereign entity • Widely recognized as “risk-free rate” • Ability and authority to print its own currency • Currency is routinely held by central banks, used in international commerce, and commonly viewed as reserve currency • Currently under the U.S. Government conservatorship or receivership Trustmark continuously monitors any changes in economic conditions, credit downgrades, changes to explicit or implicit guarantees granted to certain debt issuers, and any other relevant information that would indicate potential credit deterioration and prompt Trustmark to reconsider its zero-credit loss assumption. Securities Available for Sale FASB ASC Subtopic 326-30, “Financial Instruments-Credit Losses-Available-for-Sale Debt Securities,” replaced the concept of other-than-temporarily impaired with the ACL. Unlike securities held to maturity, securities available for sale are evaluated on an individual level and pooling of securities is not allowed. Quarterly, Trustmark evaluates if any security has a fair value less than its amortized cost. Once these securities are identified, in order to determine whether a decline in fair value resulted from a credit loss or other factors, Trustmark performs further analysis as outlined below: • Review the extent to which the fair value is less than the amortized cost and observe the security’s lowest credit rating as reported by third-party credit ratings companies. • The securities that violate the credit loss triggers above would be subjected to additional analysis that may include, but is not limited to: changes in market interest rates, changes in securities credit ratings, security type, service area economic factors, financial performance of the issuer/or obligor of the underlying issue and third-party guarantee. • If Trustmark determines that a credit loss exists, the credit portion of the allowance will be measured using a discounted cash flow (DCF) analysis using the effective interest rate as of the security’s purchase date. The amount of credit loss Trustmark records will be limited to the amount by which the amortized cost exceeds the fair value. The DCF analysis utilizes contractual maturities, as well as third-party credit ratings and cumulative default rates published annually by Moody’s Investor Service (Moody’s). Accrued interest receivable is excluded from the estimate of credit losses for securities available for sale and reported in other assets on the consolidated balance sheets. Securities Held to Maturity FASB ASC Subtopic 326-20, “Financial Instruments-Credit Losses-Measured at Amortized Cost,” requires institutions to measure expected credit losses on financial assets carried at amortized cost on a collective or pool basis when similar risks exist. Trustmark uses several levels of segmentation to measure expected credit losses for its held to maturity securities: • The portfolio is segmented into agency and non-agency securities. • The non-agency securities are separated into municipal, mortgage, and corporate securities. • Each individual segment is categorized by third-party credit ratings. As discussed above, Trustmark has determined that for certain classes of securities it would be appropriate to assume the expected credit loss to be zero, which include debt issuances of the U.S. Treasury and agencies and instrumentalities of the United States government. This assumption is reviewed and attested to quarterly. Trustmark uses an internally built model to verify the accuracy of third-party provided calculations. Accrued interest receivable is excluded from the estimate of credit losses for securities held to maturity and included in other assets on the consolidated balance sheets. Trustmark monitors the credit quality of securities held to maturity on a monthly basis through credit ratings. LHFS Trustmark's LHFS portfolio consists of mortgage loans purchased from wholesale customers or originated in Trustmark’s General Banking Segment. Trustmark has elected to account for its LHFS under the fair value option permitted by FASB ASC Topic 825, “Financial Instruments,” with interest income on the LHFS reported in interest and fees on LHFS and LHFI. Trustmark reports unrealized gains and losses resulting from changes in the fair value of the LHFS accounted for under the fair value option as noninterest income in mortgage banking, net. LHFS are actively managed and monitored and certain market risks of the loans may be mitigated through the use of derivatives. These derivative instruments are carried at fair value with changes in the fair value reported as noninterest income in mortgage banking, net. Changes in the fair value of the LHFS are largely offset by changes in the fair value of the derivative instruments. Election of the fair value option allows Trustmark to reduce the accounting volatility that would otherwise result from the asymmetry created by accounting for its LHFS at the lower of cost or fair value and the derivative instruments at fair value. Realized gains and losses upon ultimate sale of the loans are reported as noninterest income in mortgage banking, net. Government National Mortgage Association (GNMA) optional repurchase programs allow financial institutions to buy back individual delinquent mortgage loans that meet certain criteria from the securitized loan pool for which the institution provides servicing. At the servicer’s option and without GNMA’s prior authorization, the servicer may repurchase such a delinquent loan for an amount equal to 100 percent of the remaining principal balance of the loan. Under FASB ASC Topic 860, “Transfers and Servicing,” this buy-back option is considered a conditional option until the delinquency criteria are met, at which time the option becomes unconditional. When Trustmark is deemed to have regained effective control over these loans under the unconditional buy-back option, the loans can no longer be reported as sold and must be brought back onto the balance sheet as LHFS, regardless of whether Trustmark intends to exercise the buy-back option. These loans are reported as LHFS with the offsetting liability being reported as short-term borrowings. The fair value option election does not apply to the GNMA optional repurchase loans which do not meet the requirements under FASB ASC Topic 825 to be accounted for under the fair value option. Trustmark defers the upfront loan fees and costs related to the LHFS. In general, the LHFS are only retained on Trustmark’s balance sheet for 30 to 45 days before they are pooled and sold in the secondary market. The difference between deferring these loan fees and costs until the loans are sold and recognizing them in earnings as incurred as required by FASB ASC Subtopic 825-10 is considered immaterial. Deferred loan fees and costs are reflected in the basis of the LHFS and, as such, impact the resulting gain or loss when the loans are sold. LHFI LHFI are loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off and are reported at amortized cost net of the ACL. Amortized cost is the amount of unpaid principal, adjusted for the net amount of direct costs and nonrefundable loan fees associated with lending. The net amount of nonrefundable loan origination fees and direct costs associated with the lending process, including commitment fees, is deferred and accreted to interest income over the lives of the loans using a method that approximates the interest method. Interest on LHFI is accrued and recorded as interest income based on the outstanding principal balance. Past due LHFI are loans contractually past due 30 days or more as to principal or interest payments. A LHFI is classified as nonaccrual, and the accrual of interest on such loan is discontinued, when the contractual payment of principal or interest becomes 90 days past due on commercial credits and 120 days past due on non-business purpose credits. In addition, a credit may be placed on nonaccrual at any other time Management has serious doubts about further collectability of principal or interest according to the contractual terms, even though the loan is currently performing. A LHFI may remain in accrual status if it is in the process of collection and well-secured. When a LHFI is placed in nonaccrual status, interest accrued but not received is reversed against interest income. Interest payments received on nonaccrual LHFI are applied against principal under the cost-recovery method, until qualifying for return to accrual status. Under the cost-recovery method, interest income is not recognized until the principal balance is reduced to zero. LHFI are restored to accrual status when the ultimate collectability of the total contractual principal and interest is no longer in doubt and the obligation has either been brought current or has performed in accordance with the contractual terms for a reasonable period of time. Purchased Credit Deteriorated (PCD) Loans Purchased loans which have experienced more than insignificant credit deterioration since origination are considered PCD loans. An initial ACL for PCD loans is determined at acquisition using the same ACL methodology as the LHFI. The initial ACL determined on a collective basis is allocated to individual loans. PCD loans are reported at the amortized cost, which equals the loan purchased price plus the initial ACL. The difference between the amortized cost basis of the PCD loan and the par value of the loan is the noncredit premium or discount, which is amortized into interest income over the life of the loan. Subsequent changes to the ACL are recorded through the PCL, LHFI. Upon adoption of FASB ASC Topic 326, Trustmark elected to maintain pools of loans that were previously accounted for under FASB ASC Subtopic 310-30, “Receivables-Loans and Debt Securities Acquired with Deteriorated Credit Quality,” and will continue to account for these pools as a unit of account. Loans are only removed from the existing loan pools if they are written off, paid off or sold. Upon adoption of FASB ASC Topic 326, the ACL was determined for each pool and added to the pool’s carrying value to establish a new amortized cost basis. The difference between the unpaid principal balance of the pool and the new amortized cost basis is the noncredit premium or discount which will be amortized into interest income over the remaining life of the pool. Changes to the ACL after adoption of FASB ASC Topic 326 are recorded through the PCL, LHFI. ACL LHFI Trustmark’s ACL methodology for LHFI is based upon guidance within FASB ASC Subtopic 326-20 as well as applicable regulatory guidance. The ACL on LHFI is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans. Credit quality within the LHFI portfolio is continuously monitored by Management and is reflected within the ACL on LHFI. The ACL on LHFI is an estimate of expected losses inherent within Trustmark’s existing LHFI portfolio. The ACL on LHFI is adjusted through the PCL, LHFI and reduced by the charge off of loan amounts, net of recoveries. The loan loss estimation process involves procedures to appropriately consider the unique characteristics of Trustmark’s LHFI portfolio segments. These segments are further disaggregated into loan classes, the level at which credit risk is estimated. When computing allowance levels, credit loss assumptions are estimated using a model that categorizes loan pools based on loss history, delinquency status and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. Evaluations of the portfolio and individual credits are inherently subjective, as they require estimates, assumptions and judgments as to the facts and circumstances of particular situations. Determining the appropriateness of the allowance is complex and requires judgment by Management about the effect of matters that are inherently uncertain. In future periods, evaluations of the overall LHFI portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the allowance and credit loss expense. Trustmark estimates the ACL on LHFI using relevant available information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Trustmark uses a third-party software application to calculate the quantitative portion of the ACL on LHFI using a methodology and assumptions specific to each loan pool. The qualitative portion of the allowance is based on general economic conditions and other internal and external factors affecting Trustmark as a whole as well as specific LHFI. Factors considered include the following: lending policies and procedures, economic conditions and concentrations of credit, nature and volume of the portfolio, performance trends, and external factors. The quantitative and qualitative portions of the allowance are added together to determine the total ACL on LHFI, which reflects Management’s expectations of future conditions based on reasonable and supportable forecasts. The methodology for estimating the amount of expected credit losses reported in the ACL on LHFI has two basic components: a collective, or pooled, component for estimated expected credit losses for pools of loans that share similar risk characteristics, and an asset-specific component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans. In estimating the ACL for the collective component, loans are segregated into loan pools based on loan product types and similar risk characteristics. Trustmark determined that reasonable and supportable forecasts could be made for a twelve-month period for all of its loan pools. To the extent the lives of the loans in the LHFI portfolio extend beyond this forecast period, Trustmark uses a reversion period of four quarters and reverts to the historical mean on a straight-line basis over the remaining life of the loans. The ACL for individual loans that do not share risk characteristics with other loans is measured as the difference between the discounted value of expected future cash flows, based on the effective interest rate at origination, and the amortized cost basis of the loan, or the net realizable value. The ACL is the difference between the loan’s net realizable value and its amortized cost basis (net of previous charge-offs and deferred loan fees and costs), except for collateral-dependent loans. A loan is collateral dependent when the borrower is experiencing financial difficulty and repayment of the loan is expected to be provided substantially through the sale of the collateral. The expected credit loss for collateral-dependent loans is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral, adjusted for the estimated cost to sell. Fair value estimates for collateral-dependent loans are derived from appraised values based on the current market value or the ‘as is’ value of the collateral, normally from recently received and reviewed appraisals. Current appraisals are ordered on an annual basis based on the inspection date or more often if market conditions necessitate. Appraisals are obtained from state-certified appraisers and are based on certain assumptions, which may include construction or development status and the highest and best use of the property. These appraisals are reviewed by Trustmark’s Appraisal Review Department to ensure they are acceptable, and values are adjusted down for costs associated with asset disposal. If the calculated expected credit loss is determined to be permanent or not recoverable, the amount of the expected credit loss is charged off. Accrued interest receivable is not included in the amortized cost basis of Trustmark’s LHFI and, therefore, excluded from the estimate of credit losses for LHFI. LHFI are charged off against the ACL on LHFI, with any subsequent recoveries credited back to the ACL on LHFI account. Recoveries may not exceed the aggregate of amounts previously charged off. Trustmark’s Loan Policy Manual dictates the guidelines to be followed in determining when a loan is charged off. Commercial purpose LHFI are charged off when a determination is made that the loan is uncollectible and continuance as a bankable asset is not warranted. Consumer LHFI secured by 1-4 family residential real estate are generally charged off or written down to the fair value of the collateral less cost to sell at no later than 180 days of delinquency. Non-real estate consumer purpose LHFI, including both secured and unsecured loans, are generally charged off by 120 days of delinquency. Consumer revolving lines of credit and credit card debt are generally charged off on or prior to 180 days of delinquency. ACL on Off-Balance Sheet Credit Exposures Under FASB ASC Subtopic 326-20, Trustmark is required to estimate expected credit losses for off-balance sheet credit exposures which are not unconditionally cancellable. Trustmark maintains a separate ACL on off-balance sheet credit exposures, including unfunded loan commitments and letters of credit. Expected credit losses for off-balance sheet credit exposures are estimated by calculating a commitment usage factor over the contractual period for exposures that are not unconditionally cancellable by Trustmark. Trustmark calculates a loan pool level unfunded amount for the period. Trustmark views the loan pools as either closed-ended or open-ended. Closed-ended loan pools are those that typically fund up to 100% such as other construction and nonowner-occupied. Open-ended loan pools are those that behave similar to a revolver such as the commercial and industrial and home equity line of credit loan pools. In addition to the unfunded balances, Trustmark uses a funding rate for loan pools that are considered open-ended. Trustmark calculates the funding rate of the open-ended loan pools each period. In order to mitigate volatility and incorporate historical experience in the funding rate, Trustmark uses a twelve-quarter moving average. For the closed-ended loan pools, Trustmark takes a conservative approach and uses a 100% funding rate. The expected funding rate is applied to each pool’s unfunded commitment balances to ensure that reserves will be applied to each pool based on balances expected to be funded based upon historical levels. In addition to the funding rate being applied to the unfunded commitment balance, a reserve rate is applied, which includes both quantitative and a majority of the qualitative aspects of the current period's expected credit loss rate. During 2024, Management implemented a performance trends qualitative factor for unfunded commitments and an External Factor - Credit Quality Review qualitative factor for unfunded commitments. For both qualitative factors, the same assumptions are applied in the unfunded commitment calculation that are used in the funded balance calculation with the only difference being the unfunded commitment calculation includes the funding rates for the unfunded commitments. The reserves for these two qualitative factors are added to the other calculated reserve to get a total reserve for off-balance sheet credit exposures. Adjustments to the ACL on off-balance sheet credit exposures are recorded to the PCL, off-balance sheet credit exposures. No credit loss estimate is reported for off-balance sheet credit exposures that are unconditionally cancellable by Trustmark or for undrawn amounts under such arrangements that may be drawn prior to the cancellation of the arrangement. Premises and Equipment, Net Premises and equipment are reported at cost, less accumulated depreciation and amortization. Depreciation is charged to expense over the estimated useful lives of the assets, which are up to thirty-nine years for buildings and to ten years for furniture and equipment. Leasehold improvements are amortized over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. In cases where Trustmark has the right to renew the lease for additional periods, the lease term for the purpose of calculating amortization of the capitalized cost of the leasehold improvements is extended when Trustmark is “reasonably assured” that it will renew the lease. Depreciation and amortization expenses are computed using the straight-line method. Trustmark continually evaluates whether events and circumstances have occurred that indicate that such long-lived assets have become impaired. Measurement of any impairment of such long-lived assets is based on the fair values of those assets. Branch closures and purchased land held for future branch expansion for more than five years are evaluated to determine if the related land, buildings and building improvements should be transferred to assets held for sale in accordance with FASB ASC Topic 360, “Property, Plant and Equipment.” The property is transferred to assets held for sale at the lower of its carrying value or fair value less cost to sell. An impairment loss is recorded at the time of transfer if the carrying value of the assets exceeds the fair value. Impairment losses are recorded as noninterest expense in other expense. MSR Trustmark recognizes as assets the rights to service mortgage loans based on the estimated fair value of the MSR when loans are sold and the associated servicing rights are retained. Trustmark has elected to account for the MSR at fair value. The fair value of the MSR is determined using a valuation model administered by a third party that calculates the present value of estimated future net servicing income. Estimates of fair value involve several assumptions, including the key valuation assumptions about market expectations of future prepayment rates, interest rates and discount rates which are provided by a third-party firm. Prepayment rates are projected using an industry standard prepayment model. The model considers other key factors, such as a wide range of standard industry assumptions tied to specific portfolio characteristics such as remittance cycles, escrow payment requirements, geographic factors, foreclosure loss exposure, VA no-bid exposure, delinquency rates and cost of servicing, including base cost and cost to service delinquent mortgages. Prevailing market conditions at the time of analysis are factored into the accumulation of assumptions and determination of servicing value. Trustmark economically hedges changes in the fair value of the MSR attributable to interest rates. See the section titled “Derivative Financial Instruments – Derivatives Not Designated as Hedging Instruments” of this note for information regarding these derivative instruments. Trustmark receives annual servicing fee income for loans serviced, which is recorded as noninterest income in mortgage banking, net. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. Late fees and ancillary fees related to loan servicing are not considered material. Goodwill and Identifiable Intangible Assets Trustmark accounts for goodwill and other intangible assets in accordance with FASB ASC Topic 350, “Intangibles – Goodwill and Other.” Goodwill, which represents the excess of cost over the fair value of the net assets of an acquired business, is not amortized but tested for impairment on an annual basis, which is October 1 for Trustmark, or more often if events or circumstances indicate that there may be impairment. Identifiable intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or legal rights or because the assets are capable of being sold or exchanged either on their own or in combination with a related contract, asset or liability. Trustmark’s identifiable intangible assets primarily relate to core deposits and borrower relationships. These intangibles, which have definite useful lives, are amortized on an accelerated basis over their estimated useful lives. In addition, these intangibles are evaluated for impairment whenever events and changes in circumstances indicate that the carrying amount should be reevaluated. Trustmark also purchased banking charters in order to facilitate its entry into the states of Florida and Texas. These identifiable intangible assets were amortized on a straight-line method over 20 years. Other Real Estate Other real estate includes assets that have been acquired in satisfaction of debt through foreclosure and is recorded at the fair value less cost to sell (estimated fair value) at the time of foreclosure. Fair value is based on independent appraisals and other relevant factors. When foreclosed real estate is received in full satisfaction of a loan, the amount, if any, by which the recorded amount of the loan exceeds the estimated fair value of the property is a loss charged against the ACL at the time of foreclosure. If the recorded amount of the loan is less than the estimated fair value of the property, a credit is recorded to write-downs of other real estate at the time of foreclosure. Other real estate is revalued on an annual basis or more often if market conditions necessitate. An other real estate specific reserve may be recorded through other real estate expense for declines in fair value subsequent to foreclosure based on recent appraisals or changes in market conditions. Subsequent to foreclosure, losses on the periodic revaluation of the property are charged against an existing other real estate specific reserve or as noninterest expense in other real estate expense if a reserve does not exist. Costs of operating and maintaining the properties as well as gains or losses on their disposition are also included in other real estate expense as incurred. Improvements made to properties are capitalized if the expenditures are expected to be recovered upon the sale of the properties. Leases Lessor Arrangements Trustmark leases certain types of machinery and equipment to its commercial customers through sales-type and direct financing leases as part of its equipment financing portfolio. Sales-type and direct financing leases are similar to other forms of installment lending in that lessors generally do not retain benefits and risks incidental to ownership of the property subject to the leases. Such arrangements are essentially financing transactions that permit lessees to acquire and use property. Trustmark does not have any significant operating leases in which it is the lessor. As lessor, the sum of all minimum lease payments over the lease term and the estimated residual value, less unearned interest income, is recorded as the net investment in the lease on the commencement date and is included in LHFI on the consolidated balance sheets. Interest income is accrued as earned over the term of the lease based on the net investment in the leases and is recognized in interest and fees on LHFS and LHFI on the consolidated statements of income. Certain fees or costs associated with lease originations are deferred and accreted or amortized to interest income over the life of the lease using the effective interest method. Trustmark’s portfolio of sales-type and direct financing leases generally have remaining lease terms of three to ten years, some of which include renewal options and/or options for the lessee to purchase the leased property near or at the end of the lease term at either the residual value or a specified price. Trustmark expects to sell or release the equipment at the end of the lease term. Due to the structure of these leases, there is no selling profit or loss on these transactions. Lessee Arrangements Trustmark has certain contracts that it has identified as leases according to FASB ASC Topic 842, "Leases". Trustmark classifies these leases as either operating or finance leases and recognizes a right-of-use asset and a lease liability at the lease commencement date. The lease liability represents the present value of the lease payments that remain unpaid as of the commencement date and the right-of-use asset is the initial lease liability recognized for the lease plus any lease payments made to the lessor at or before the commencement date as well as any initial direct costs less any lease incentives received. Trustmark accounts for the lease and nonlease components separately as such amounts are readily determinable. Trustmark’s finance leases consist of building and equipment leases. Trustmark recognizes interest expense based on the discount rate of the lease as interest expense in other interest expense and recognizes depreciation expense on a straight-line basis over the lease term as noninterest expense in net occupancy – premises for building leases and in equipment expense for equipment leases. Trustmark amortizes the right-of-use asset over the life of the lease term on a straight-line basis. Trustmark’s lease liabilities are measured as the present value of the remaining lease payments throughout the lease term. Trustmark records its finance lease right-of-use assets in premises and equipment, net and its finance lease liabilities in other borrowings. Trustmark’s operating leases primarily consist of building and land leases. Trustmark recognizes lease rent expense on a straight-line basis over the term of the lease contract and records it as noninterest expense in net occupancy – premises for building and land leases and in equipment expense for equipment leases. Trustmark’s amortization of the right-of-use asset is the difference between the straight-line lease expense and the interest expense recognized on the lease liability during the period. Trustmark’s lease liabilities are measured as the present value of the remaining lease payments throughout the lease term. Trustmark’s leases typically have one or more renewal options included in the lease contract. Due to the nature of Trustmark’s leases, for leases with renewal options available, Trustmark considers the first renewal option as reasonably certain to renew and is therefore included in the measurement of the right-of-use assets and lease liabilities. In order to calculate its right-of-use assets and lease liabilities, FASB ASC Topic 842 requires Trustmark to use the rate of interest implicit in the lease when readily determinable. If the rate implicit in the lease is not readily determinable, Trustmark is required to use its incremental borrowing rate, which is the rate of interest Trustmark would have to pay to borrow on a collateralized basis over a similar term in a similar economic environment. Trustmark was able to determine the implicit interest rate for its equipment leases and used that rate as its discount rate. Since the implicit interest rate for most of its building and land leases were not readily determinable, Trustmark used its incremental borrowing rate. Trustmark made an accounting policy election to not recognize short-term leases (12 months or less) on the balance sheet. Trustmark’s short-term leases primarily include automated teller machines. For short-term leases, Trustmark recognizes lease expense on a straight-line basis over the lease term. Federal Home Loan Bank (FHLB) and Federal Reserve Bank of Atlanta Stock Trustmark accounts for its investments in FHLB and Federal Reserve Bank of Atlanta stock in accordance with FASB ASC Subtopic 942-325, “Financial Services-Depository and Lending-Investments-Other.” FHLB and Federal Reserve Bank stock are equity securities that do not have a readily determinable fair value because its ownership is restricted and it lacks a market. FHLB and Federal Reserve Bank stock are carried at cost and evaluated for impairment. Trustmark’s investment in member bank stock is included in other assets in the accompanying consolidated balance sheets. At December 31, 2024 and 2023, Trustmark’s investment in member bank stock totaled $44.9 million and $54.4 million, respectively. The carrying value of Trustmark’s member bank stock gave rise to no other-than-temporary impairment for the years ended December 31, 2024, 2023 and 2022. Revenue from Contracts with Customers Trustmark accounts for revenue from contracts with customers in accordance with FASB ASC Topic 606, “Revenue from Contracts with Customers,” which provides that revenue be recognized in a manner that depicts the transfer of goods or services to a customer in an amount that reflects the consideration Trustmark expects to be entitled to in exchange for those goods or services. Revenue from contracts with customers is recognized either over time in a manner that depicts Trustmark’s performance, or at a point in time when control of the goods or services are transferred to the customer. Trustmark’s noninterest income, excluding all of mortgage banking, net and securities gains (losses), net and portions of bank card and other fees and other, net, are considered within the scope of FASB ASC Topic 606. Gains or losses on the sale of other real estate, which are included in Trustmark’s noninterest expense as other expense, are also within the scope of FASB ASC Topic 606. General Banking Segment Service Charges on Deposit Accounts In general, deposit accounts represent contracts with customers with no fixed duration and can be terminated or modified by either party at any time without compensation to the other party. According to FASB ASC Topic 606, a contract that can be terminated by either party without compensation does not exist for periods beyond the then-current period. Therefore, deposit contracts are considered to renew day-to-day if not minute-to-minute. Deposit contracts have a single continuous or stand-ready service obligation whereby Trustmark makes customer funds available for use by the customer as and when the customer chooses as well as other services such as statement rendering and online banking. The specific services provided vary based on the type of deposit account. These services are not individually distinct, but are distinct as a group, and therefore, constitute a single performance obligation which is satisfied over time and qualifies as a series of distinct service periods. Trustmark receives a fixed service charge amount as consideration monthly for services rendered. The service charge amount varies based on the type of deposit account. Some of the service charge revenue is subject to refund provisions, which is variable consideration under the guidelines of FASB ASC Topic 606. Trustmark has elected the ‘as-invoiced’ practical expedient permitted under FASB ASC Topic 606 for recognition of service charge revenue. Therefore, revenue is recognized at the time and in the amount the customer is charged. The service charge revenue is presented net of refunded amounts on Trustmark’s consolidated statements of income. Services related to non-sufficient funds, overdrafts, excess account activity, stop payments, dormant accounts, etc. are considered optional purchases for a deposit contract because there is no performance obligation for Trustmark until the service is requested by the customer or the occurrence of a triggering event. Fees for these services are fixed amounts and are charged to the customer when the service is performed. Revenue is recognized at the time the customer is charged. Bank Card and Other Fees Revenue from contracts with customers in bank card and other fees includes income related to interchange fees and various other contracts which primarily consists of contracts with a single performance obligation that is satisfied at a point in time. Trustmark receives a fixed consideration amount once the performance obligation is completed for these contracts. Trustmark reports revenue from these contracts net of amounts refunded or due to a third party. As both a debit and credit card issuer, Trustmark receives an interchange fee for every card transaction completed by its customers with a merchant. Trustmark receives two types of interchange fees: point-of-sale transactions in which the customer must enter the PIN associated with the card to complete the transaction (a debit card transaction), and signature transactions in which the signature of the customer is required to complete the transaction (a credit card transaction). Trustmark, as the card issuing or settlement bank, has a contract (implied based on customary business practices) with the payment network in which Trustmark has a single continuous service obligation to make funds available for settlement of the card transaction. Trustmark’s service obligation is satisfied over time and qualifies as a series of distinct service periods. Trustmark receives interchange fees as consideration for services rendered in the amount established by the respective payment network. The interchange fees are established by the payment network based on the type of transaction and is posted on their website. Trustmark receives and records interchange fee revenue from the payment networks daily net of all fees and amounts due to the payment network. Other Income Revenue from contracts with customers in other income includes income related to cash management services and other contracts with a single performance obligation that is satisfied at a point in time. Trustmark receives a fixed consideration amount once the performance obligation is completed for these contracts. Trustmark reports revenue from these contracts net of amounts refunded or due to a third party. Trustmark provides cash management services through the delivery of various products and services offered to its business and municipal customers including various departments of state, city and local governments, universities and other non-profit entities. Similar to the deposit account contracts, the cash management contracts primarily represent contracts with customers with no fixed duration and can be terminated or modified by either party at any time without compensation to the other party. Therefore, cash management contracts are generally considered to renew day-to-day if not minute-to-minute. Cash management contracts have a single continuous or stand-ready service obligation whereby Trustmark makes a specific service or group of services available for use by the customer as and when the customer chooses. The specific services provided vary based on the type of account or product. These services are not individually distinct, but are distinct as a group, and therefore, constitute a single performance obligation which is satisfied over time and qualifies as a series of distinct service periods. Trustmark receives a set service charge or maintenance fee amount as consideration monthly for services rendered. However, some of the fees are based on the number of transactions that occur (i.e., flat fee for a set number of transactions per month then an additional charge for each transaction after that) or the average daily account balance maintained by the customer during the month and a small amount of the cash management fee revenue is subject to refund provisions. These fees represent variable consideration under the guidelines of FASB ASC Topic 606. Trustmark has elected the ‘as-invoiced’ practical expedient permitted under FASB ASC Topic 606 for recognition of cash management fee revenue. The cash management revenue is presented net of any refunded amounts on Trustmark’s consolidated statements of income. Trustmark’s merchant services provider contracts directly with Trustmark business customers and provides Trustmark’s merchant customers card processing equipment and transaction processing services. Trustmark’s contract with the merchant services provider has a single-continuous service obligation to provide customer referrals for potential new accounts which is satisfied over time and qualifies as a series of distinct service periods. Trustmark receives a flat fee for each new account established and a percentage of the residual income related to transactions processed for Trustmark’s merchant customers each month as provided in the contract. Under the guidelines of FASB ASC Topic 606, the fee received for each new account and the profit sharing represent variable consideration. Revenue from merchant card services contracts is recognized monthly using a time-elapsed measure of progress. Trustmark has elected the ‘as-invoiced’ practical expedient permitted under FASB ASC Topic 606 for recognition of the merchant card services revenue. Other Real Estate Trustmark records a gain or loss from the sale of other real estate when control of the property transfers to the buyer. Trustmark records the gain or loss from the sale of other real estate in noninterest expense as other expense. Other real estate sales for the year ended December 31, 2024 resulted in a net loss of $1.1 million compared to a net loss of $145 thousand for the year ended December 31, 2023 and a net loss of $1.0 million for the year ended December 31, 2022. In general, purchases of Trustmark’s other real estate property are not financed by Trustmark. Financing the purchase of other real estate is evaluated based upon the same lending policies and procedures as all other types of loans. Under FASB ASC Subtopic 610-20, “Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets,” when Trustmark finances the sale of its other real estate to a buyer, Trustmark is required to assess whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these two criteria are met, Trustmark derecognizes the other real estate asset and records a gain or loss on the sale once control of the property is transferred to the buyer. Wealth Management Segment Trust Management There are four categories of revenue included in trust management: personal trust and investments, retirement plan services, institutional custody and other. Each of these categories includes multiple types of contracts, service obligations and fee income. However, the majority of these contracts include a single service obligation that is satisfied over time, the customer is charged in arrears for services rendered and revenue is recognized when payment is received. In general, the time period between when the service obligation is completed and when payment from the customer is received is less than 30 days. Revenue from trust management contracts is primarily related to monthly service periods and based on the prior month-end’s market value. Some trust management revenue is mandated by a court order, while other revenue consists of flat fees. Trust management revenue based on an account’s market value represents variable consideration under the guidelines of FASB ASC Topic 606. Trustmark has elected the ‘as-invoiced’ practical expedient allowed under FASB ASC Topic 606 to account for the trust management revenue. Assets under administration held by Trustmark in a fiduciary or agency capacity for customers are not included in Trustmark’s consolidated balance sheets. Investment Services Investment services includes both brokerage and annuity income. Trustmark has a contract with a third-party investment services company which contains a single continuous service obligation, to provide broker-dealer and advisory services to customers on behalf of the third-party, which is satisfied over time and qualifies as a series of distinct service periods. Trustmark serves as the agent between the third-party investment services company, the principle, and the customer. In accordance with the contract, Trustmark receives a monthly payment from the investment services company for commissions and advisory fees (asset management fees) earned on transactions completed in the prior month net of all charges and fees due to the investment services company. Trustmark recognizes revenue from the investment services company, net of the revenue sharing expense due to the investment services company, when the payments are received. Commissions vary from month-to-month based on the specific products and transactions completed. The advisory fees vary based on the average daily balance of the managed assets for the period. The commissions and advisory fees represent variable consideration under FASB ASC Topic 606. Trustmark has elected the ‘as-invoiced’ practical expedient allowed under FASB ASC Topic 606 to recognize revenue from the investment services company. Derivative Financial Instruments Trustmark maintains an overall interest rate risk management strategy that incorporates the use of derivative instruments to minimize significant unplanned fluctuations in earnings and cash flows caused by interest rate volatility. Trustmark’s interest rate risk management strategy involves modifying the repricing characteristics of certain assets and liabilities so that changes in interest rates do not adversely affect the net interest margin and cash flows. Under the guidelines of FASB ASC Topic 815, “Derivatives and Hedging,” all derivative instruments are required to be recognized as either assets or liabilities and carried at fair value on the balance sheet. The fair value of derivative positions outstanding is included in other assets and/or other liabilities in the accompanying consolidated balance sheets and in the net change in these financial statement line items in the accompanying consolidated statements of cash flows as well as included in noninterest income in the accompanying consolidated statements of income and other comprehensive income (loss), net of tax in the accompanying consolidated statements of comprehensive income. Trustmark’s interest rate derivative instruments are subject to master netting agreements, and therefore, eligible for offsetting in the consolidated balance sheets. Trustmark has elected to not offset any derivative instruments in its consolidated balance sheets. Derivatives Designated as Hedging Instruments FASB ASC Topic 815, Derivatives and Hedging (ASC 815), provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments. Derivatives designated and qualifying as a hedge of the 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. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. When entering into a hedge transaction, Trustmark formally documents the relationship between the hedging instrument and the hedged item, as well as the risk management objective and strategy for undertaking the hedge transaction, which includes designating the derivative instrument as a fair value or cash flow hedge to a specific asset or liability on the balance sheet or to specific forecasted transactions and the risk being hedged, along with a formal assessment at the inception of the hedge as to the effectiveness of the derivative instrument in offsetting changes in fair values or cash flows of the hedged item. Trustmark continues to assess hedge effectiveness on an ongoing basis using either a qualitative or a quantitative assessment (regression analysis). As required by ASC 815, Trustmark records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether Trustmark has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. For cash flow hedges, changes in the fair value of the derivative instrument are recorded in accumulated other comprehensive income (loss) and subsequently reclassified to net income in the same period that the hedged transaction impacts net income. Upon discontinuation of hedge accounting for cash flow hedges, any amounts in accumulated other comprehensive income (loss) related to that relationship affects earnings at the same time and in the same manner in which the hedged transaction affects earnings. If it becomes probable that the forecasted transaction will not occur, any related amounts in accumulated other comprehensive income (loss) are reclassified to earnings immediately. Derivatives Not Designated as Hedging Instruments As part of Trustmark’s risk management strategy in the mortgage banking area, derivative instruments such as forward sales contracts are utilized. Trustmark’s obligations under forward contracts consist of commitments to deliver mortgage loans, originated and/or purchased, in the secondary market at a future date. Changes in the fair value of these derivative instruments are recorded as noninterest income in mortgage banking, net and are offset by changes in the fair value of LHFS. See Note 1 – Significant Accounting Policies, “LHFS” for information regarding the fair value option election. Trustmark also utilizes derivative instruments such as interest rate lock commitments in its mortgage banking area. Rate lock commitments are residential mortgage loan commitments with customers, which guarantee a specified interest rate for a specified time period. Changes in the fair value of these derivative instruments are recorded as noninterest income in mortgage banking, net and are offset by the changes in the fair value of forward sales contracts. Trustmark utilizes a portfolio of exchange-traded derivative instruments, such as Treasury note futures contracts and option contracts, to achieve a fair value return that economically hedges changes in the fair value of the MSR attributable to interest rates. These transactions are considered freestanding derivatives that do not otherwise qualify for hedge accounting. These exchange-traded derivative instruments are accounted for at fair value with changes in the fair value recorded as noninterest income in mortgage banking, net and are offset by changes in the fair value of the MSR. The MSR fair value represents the present value of future cash flows, which among other things includes decay and the effect of changes in interest rates. Ineffectiveness of hedging the MSR fair value is measured by comparing the change in the fair value of the hedge instruments to the change in the fair value of the MSR asset attributable to changes in interest rates and other market driven changes in valuation inputs and assumptions. Trustmark offers certain derivatives products directly to qualified commercial lending clients seeking to manage their interest rate risk. Trustmark economically hedges interest rate swap transactions executed with commercial lending clients by entering into offsetting interest rate swap transactions with institutional derivatives market participants. Derivative transactions executed as part of this program are not designated as qualifying hedging relationships and are, therefore, carried at fair value with the change in fair value recorded as noninterest income in bank card and other fees. Because these derivatives have mirror-image contractual terms, in addition to collateral provisions which mitigate the impact of non-performance risk, the changes in fair value are expected to substantially offset. The offsetting interest rate swap transactions are either cleared through the Chicago Mercantile Exchange for clearable transactions or booked directly with institutional derivatives market participants for non-clearable transactions. The Chicago Mercantile Exchange rules legally characterize variation margin collateral payments made or received for centrally cleared interest rate swaps as settlements rather than collateral. As a result, centrally cleared interest rate swaps included in other assets and other liabilities are presented on a net basis in the accompanying consolidated balance sheets. Income Taxes Trustmark accounts for uncertain tax positions in accordance with FASB ASC Topic 740, “Income Taxes,” which clarifies the accounting and disclosure for uncertainty in tax positions. Under the guidance of FASB ASC Topic 740, Trustmark accounts for deferred income taxes using the liability method. Deferred tax assets and liabilities are based on temporary differences between the financial statement carrying amounts and the tax basis of Trustmark’s assets and liabilities. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be realized or settled and are presented net in the accompanying consolidated balance sheets in other assets. Stock-Based Compensation Trustmark accounts for the stock and incentive compensation under the provisions of FASB ASC Topic 718, “Compensation – Stock Compensation.” Under this accounting guidance, fair value is established as the measurement objective in accounting for stock awards and requires the application of a fair value based measurement method in accounting for compensation cost, which is recognized over the requisite service period. Trustmark has elected to account for forfeitures of stock awards as they occur. Statements of Cash Flows For purposes of reporting cash flows, cash and cash equivalents include cash on hand and amounts due from banks. The following table reflects specific transaction amounts for the periods presented ($ in thousands):
Per Share Data Trustmark accounts for per share data in accordance with FASB ASC Topic 260, “Earnings Per Share,” which provides that unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of EPS pursuant to the two-class method. Trustmark has determined that its outstanding unvested stock awards are not participating securities. Based on this determination, no change has been made to Trustmark’s current computation for basic and diluted EPS. Basic EPS is computed by dividing net income by the weighted-average shares of common stock outstanding. Diluted EPS is computed by dividing net income by the weighted-average shares of common stock outstanding, adjusted for the effect of potentially dilutive stock awards outstanding during the period. The following table reflects weighted-average shares used to calculate basic and diluted EPS for the periods presented (in thousands):
Weighted-average antidilutive stock awards were excluded in determining diluted EPS. The following table reflects weighted-average antidilutive stock awards for the periods presented (in thousands):
Fair Value Measurements FASB ASC Topic 820, “Fair Value Measurements and Disclosures,” defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and requires certain disclosures about 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. Depending on the nature of the asset or liability, Trustmark uses various valuation techniques and assumptions when estimating fair value. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. FASB ASC Topic 820 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 – Valuation is based upon quoted prices (unadjusted) in active markets for identical assets or liabilities that Trustmark has the ability to access at the measurement date. Level 2 Inputs – Valuation is based upon quoted prices in active markets for similar assets or liabilities, 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, yield curves, volatilities and default rates and inputs that are derived principally from or corroborated by observable market data. Level 3 Inputs – Unobservable inputs reflecting the reporting entity’s own determination about the assumptions that market participants would use in pricing the asset or liability based on the best information available. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the fair value measurement in its entirety is classified is based on the lowest level input that is significant to the fair value measurement in its entirety. Trustmark’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer. Accounting Policies Recently Adopted Except for the changes detailed below, Trustmark has consistently applied its accounting policies to all periods presented in the accompanying consolidated financial statements. ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” Issued in November 2023, ASU 2023-07 is intended to improve disclosures about a public entity’s reportable segments and address requests from investors and other allocators of capital for additional, more detailed information about a reportable segment’s expenses. The amendments of ASU 2023-07 require a public entity to disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and included within each reported measure of segment profit or loss, and an amount for other segment items by reportable segment and a description of its composition. The other segment items category is the difference between segment revenue less the significant expenses disclosed and each reported measure of segment profit or loss. ASU 2023-07 also requires a public entity to provide all annual disclosures about a reportable segment’s profit or loss and assets currently required under FASB ASC Topic 280 in interim periods. The amendments of ASU 2023-07 clarify that if the CODM uses more than one measure of a segment's profit or loss in assessing segment performance and deciding how to allocate resources, a public entity may report one or more of those additional measures of segment profit. However, at least one of the reported segment profit or loss measures (or the single reported measure if only one is disclosed) should be the measure that is most consistent with the measurement principles used in measuring the corresponding amounts in the public entity's consolidated financial statements. ASU 2023-07 requires a public entity to disclose the title and position of the CODM, together with an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. In addition, ASU 2023-07 requires that a public entity with a single reportable segment provide all the disclosures required by the amendments of ASU 2023-07 and all existing segment disclosures in FASB ASC Topic 280. The amendments of ASU 2023-07 are effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments in ASU 2023-07 should be applied retrospectively to all periods presented on the financial statements. Upon implementation, the segment expense categories and amounts disclosed in the prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. Trustmark adopted the amendments of ASU 2023-07 related to annual disclosure requirements effective January 1, 2024, and the newly required annual disclosures are included in Note 21 – Segment Information of this report. Trustmark adopted the amendments of ASU 2023-07 related to interim disclosure requirements effective January 1, 2025, and will present any newly required interim disclosures beginning with its Quarterly Report on Form 10-Q for the period ending March 31, 2025. Adoption of ASU 2023-07 did not have a material impact to Trustmark’s consolidated financial statements or results of operations. ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” Issued in December 2023, ASU 2023-09 is intended to improve the disclosures for income taxes to address requests from investors, lenders, creditors and other allocators of capital (collectively, "investors") that use the financial statements to make capital allocation decisions. During the FASB's 2021 agenda consultation process and other stakeholder outreach, investors highlighted that the current system of income tax disclosures does not provide enough information to understand the tax provision for an entity that operates in multiple jurisdictions. Investors currently rely on the rate reconciliation table and other disclosures, including total income taxes paid in the statement of cash flows, to evaluate income tax risks and opportunities. The amendments in ASU 2023-09 will require consistent categories and greater disaggregation of information in the rate reconciliation disclosure as well as disclosure of income taxes paid disaggregated by jurisdiction. The amendments of ASU 2023-09 are effective for annual periods beginning after December 15, 2024, and early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. Trustmark adopted the amendments of ASU 2023-09 effective January 1, 2025, and will include the required disclosures in its Annual Report on Form 10-K for the year ending December 31, 2025. Trustmark is currently evaluating the changes to disclosures required by ASU 2023-09; however, adoption of ASU 2023-09 is not expected to have a material impact to Trustmark’s consolidated financial statements or results of operations. Pending Accounting Pronouncements ASU 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” Issued in November 2024, ASU 2024-03 with the objective of providing investors with more decision-useful information regarding a public business entity's expenses by enhancing disclosures on income statement expenses. Investor feedback indicated a strong preference for the disclosure of disaggregated financial reporting information as a top priority for the FASB. Detailed knowledge of an entity's expenses is crucial for understanding its prospects for future cash flows and for making performance comparisons over time and with other entities. Investors emphasized that information regarding cost of sales, selling, general, and administrative expenses, employee compensation costs, depreciation and amortization, and research and development expenditure would enhance their comprehension of an entity's cost structure and ability to forecast future cash flows. The ASU applies exclusively to public business entities and mandates additional disclosures about specific expense categories on both annual and interim bases in the notes to financial statements that are not currently required. The amendments do not alter or eliminate existing expense disclosure requirements nor change requirements for presenting expenses on the face of the income statement. However, they do specify that certain existing disclosures must now appear in the same tabular format as the new disaggregation requirements. The FASB issued ASU 2025-01 in January 2025, clarifying that the amendments in ASU 2024-03 are effective for public business entities for annual reporting periods beginning after December 15, 2026, and for interim reporting periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. Trustmark intends to adopt the amendments of ASU 2024-03 effective January 1, 2027, and will include the required annual disclosures in its Annual Report on Form 10-K for the year ending December 31, 2027, and required interim disclosures in its Quarterly Report on Form 10-Q for the period ending March 31, 2028. Trustmark is currently evaluating the changes to disclosures required by ASU 2024-03; however, adoption of ASU 2024-03 is not expected to have a material impact to Trustmark’s consolidated financial statements or results of operations. |

| Discontinued Operations | Note 2 - Discontinued Operations On May 31, 2024, Trustmark National Bank (TNB) completed the sale of its wholly owned subsidiary, Fisher Brown Bottrell Insurance, Inc. (FBBI), to Marsh & McLennan Agency LLC (MMA) for approximately $336.9 million in cash. The transaction resulted in a pre-tax of $228.3 million. The gain, along with FBBI's historical financial results for periods prior to the sale, is reflected in Trustmark's consolidated financial statements as discontinued operations. The assets and liabilities of FBBI have been presented as "Assets of discontinued operations" and "Liabilities of discontinued operations" on the consolidated balance sheet at December 31, 2023. FBBI's operating results have been presented as "Discontinued operations" within the accompanying consolidated statements of income and prior period amounts have been reclassified to conform with the current period presentation. Cash flows from both continuing and discontinued operations are included in the Consolidated Statements of Cash Flows. The following table summarizes financial information related to FBBI which has been segregated from continuing operations and reported as discontinued operations for the periods presented ($ in thousands):

| Securities Available for Sale and Held to Maturity | Note 4 – Securities Available for Sale and Held to Maturity The following tables are a summary of the amortized cost and estimated fair value of securities available for sale and held to maturity at December 31, 2024 and 2023 ($ in thousands):
During 2022, Trustmark reclassified a total of $766.0 million of securities available for sale to securities held to maturity. On the date of these transfers, the net unrealized holding loss on the available for sale securities totaled approximately $91.9 million ($68.9 million, net of tax). The securities were transferred at fair value, which became the cost basis for the securities held to maturity. The net unrealized holding loss will be amortized over the remaining life of the securities as a yield adjustment in a manner consistent with the amortization or accretion of the original purchase premium or discount on the associated security. There were no gains or losses recognized as a result of these transfers. At December 31, 2024, the net unamortized, unrealized loss on transferred securities included in accumulated other comprehensive income (loss) in the accompanying balance sheet totaled $46.6 million compared to approximately $57.6 million at December 31, 2023. ACL on Securities Securities Available for Sale Quarterly, Trustmark evaluates if any security has a fair value less than its amortized cost. Once these securities are identified, in order to determine whether a decline in fair value resulted from a credit loss or other factors, Trustmark performs further analysis. If Trustmark determines that a credit loss exists, the credit portion of the allowance is measured using a DCF analysis using the effective interest rate as of the security’s purchase date. The amount of credit loss Trustmark records will be limited to the amount by which the amortized cost exceeds the fair value. The DCF analysis utilizes contractual maturities, as well as third-party credit ratings and cumulative default rates published annually by Moody’s. At both December 31, 2024 and 2023, the results of the loss analysis performed did not identify any securities that warranted DCF analysis and no credit loss was recognized on any of the securities available for sale. Accrued interest receivable is excluded from the estimate of credit losses for securities available for sale. At December 31, 2024 and 2023, accrued interest receivable totaled $5.0 million and $3.7 million, respectively, for securities available for sale and was reported in other assets on the accompanying consolidated balance sheet. Securities Held to Maturity At December 31, 2024, Trustmark identified no securities held to maturity with the potential for credit loss exposure, compared to $340 thousand at December 31, 2023, which consisted of municipal securities. After applying appropriate probability of default and loss given default assumptions, the total amount of current expected credit losses was zero at December 31, 2024 and immaterial at December 31, 2023. Therefore, no reserve was recorded at either December 31, 2024 or December 31, 2023. Accrued interest receivable is excluded from the estimate of credit losses for securities held to maturity. At December 31, 2024 and 2023, accrued interest receivable totaled $2.4 million and $2.6 million for securities held to maturity and was reported in other assets on the accompanying consolidated balance sheet. At both December 31, 2024 and 2023, Trustmark had no securities held to maturity that were past due 30 days or more as to principal or interest payments. Trustmark had no securities held to maturity classified as nonaccrual at December 31, 2024 and 2023. Trustmark monitors the credit quality of securities held to maturity on a monthly basis through credit ratings. The following table presents the amortized cost of Trustmark’s securities held to maturity by credit rating, as determined by Moody’s, at December 31, 2024 and 2023 ($ in thousands):
(1) Not rated securities primarily consist of Mississippi municipal general obligations. The tables below include securities with gross unrealized losses for which an ACL has not been recorded and segregated by length of impairment at December 31, 2024 and 2023 ($ in thousands):
The unrealized losses shown above are due to increases in market rates over the yields available at the time of purchase of the underlying securities and not credit quality. Trustmark does not intend to sell these securities and it is more likely than not that Trustmark will not be required to sell the investments before recovery of their amortized cost bases, which may be at maturity. Securities Gains and Losses Realized gains and losses are determined using the specific identification method and are included in noninterest income (loss) as securities gains (losses), net. For the periods presented, gross realized gains or losses as a result of calls and dispositions of securities, as well as any associated proceeds, were as follows ($ in thousands):
During the second quarter of 2024, Trustmark restructured its investment securities portfolio by selling $1.561 billion of available for sale securities with an average yield of 1.36%, which generated a loss of $182.8 million ($137.1 million, net of taxes) and was recorded to noninterest income (loss) in securities gains (losses), net. Proceeds from the sale were used to purchase $1.378 billion of available for sale securities with an average yield of 4.85%. Securities Pledged Securities with a carrying value of $1.910 billion and $2.321 billion at December 31, 2024 and 2023, respectively, were pledged to collateralize public deposits and securities sold under repurchase agreements and for other purposes as permitted by law. At both December 31, 2024 and 2023, none of these securities were pledged under the Federal Reserve Discount Window program to provide additional contingency funding capacity. Contractual Maturities The amortized cost and estimated fair value of securities available for sale and held to maturity at December 31, 2024, by contractual maturity, are shown below ($ in thousands). Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

| LHFI and ACL, LHFI | Note 5 – LHFI and ACL, LHFI At December 31, 2024 and 2023, LHFI consisted of the following ($ in thousands):
Accrued interest receivable is not included in the amortized cost basis of Trustmark’s LHFI. At December 31, 2024 and 2023, accrued interest receivable for LHFI totaled $64.7 million and $71.0 million, respectively, with no related ACL and was reported in other assets on the accompanying consolidated balance sheet. Loan Concentrations Trustmark does not have any loan concentrations other than those reflected in the preceding table, which exceed 10% of total LHFI. At December 31, 2024, Trustmark’s geographic loan distribution was concentrated primarily in its six key market regions: Alabama, Florida, Georgia, Mississippi, Tennessee and Texas. Accordingly, the ultimate collectability of a substantial portion of these loans is susceptible to changes in market conditions in these areas. Related Party Loans At December 31, 2024 and 2023, loans to certain executive officers and directors, including their immediate families and companies in which they are principal owners, totaled $33.1 million and $41.1 million, respectively. During 2024, $235.9 million of new loan advances were made, while repayments were $243.9 million. There were no increases in loans due to changes in executive officers and directors. Nonaccrual and Past Due LHFI No material interest income was recognized in the income statement on nonaccrual LHFI for each of the years in the three-year period ended December 31, 2024. The following tables provide the amortized cost basis of loans on nonaccrual status and loans past due 90 days or more still accruing interest at December 31, 2024 and 2023 ($ in thousands):
The following tables provide an aging analysis of the amortized cost basis of past due LHFI (including nonaccrual loans) at December 31, 2024 and 2023 ($ in thousands):
Modified LHFI Occasionally, Trustmark modifies loans for borrowers experiencing financial difficulties by providing payment concessions, interest-only payments for an extended period of time, maturity extensions or interest rate reductions. Other concessions may arise from court proceedings or may be imposed by law. In some cases, Trustmark provides multiple types of concessions on one loan. The following tables present the amortized cost of LHFI at the end of each of the periods presented of loans modified to borrowers experiencing financial difficulty disaggregated by class of loan and type of modification ($ in thousands). The percentage of the amortized cost basis of LHFI that were modified to borrowers in financial distress as compared to the amortized cost basis of each class of LHFI is also presented below:
The following tables detail the financial effect of the loan modifications presented above to borrowers experiencing financial difficulty for the periods presented:
Trustmark had no unused commitments on modified loans to borrowers experiencing financial difficulty at December 31, 2024 or December 31, 2023.
During the year ended December 31, 2024, Trustmark had a payment concession balance of $6.2 million and a term extension balance of $70 thousand at default for LHFI in the commercial and industrial portfolio and the other secured by 1-4 family residential properties portfolio, respectively, that had a payment default and were modified within the twelve months prior to that default to borrowers experiencing financial difficulty. During the year ended December 31, 2023, Trustmark had payment concession balances of $116 thousand at default for LHFI in the other commercial loans and leases portfolio that had a payment default and were modified within the twelve months prior to that default to borrowers experiencing financial difficulty. Trustmark has utilized loans 90 days or more past due to define payment default in determining modified loans that have subsequently defaulted. If Trustmark determines that a modified loan (or a portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is charged off against the ACL, LHFI. Trustmark closely monitors the performance of loans that are modified to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. The following tables provide details of the performance of such LHFI that have been modified during the periods presented ($ in thousands):
Collateral-Dependent Loans The following tables present the amortized cost basis of collateral-dependent loans by class of loans and collateral type at December 31, 2024 and 2023 ($ in thousands):
A loan is collateral dependent when the borrower is experiencing financial difficulty and repayment of the loan is expected to be provided substantially through the sale of the collateral. The following provides a qualitative description by class of loan of the collateral that secures Trustmark’s collateral-dependent LHFI: • Loans secured by real estate – Loans within these loan classes are secured by liens on real estate properties. During 2024, one collateral dependent relationship had a decrease in collateral value that secures the credit. There have been no other significant changes to the collateral that secures these financial assets during the period. • Other loans secured by real estate – Loans within these loan classes are secured by liens on real estate properties. There have been no significant changes to the collateral that secures these financial assets during the period. • Commercial and industrial loans – Loans within this loan class are primarily secured by inventory, accounts receivables, equipment and other non-real estate collateral. During 2024, four relationships had decreases in collateral value that secures the credit. There have been no other significant changes to the collateral that secures these financial assets during the period. • State and other political subdivision loans – Loans within this loan class are secured by liens on real estate properties or other non-real estate collateral. There have been no significant changes to the collateral that secures these financial assets during the period. • Other commercial loans and leases – Loans and leases within this loan class are secured by non-real estate collateral. There have been no significant changes to the collateral that secures these financial assets during the period. Credit Quality Indicators Trustmark’s LHFI portfolio credit quality indicators focus on six key quality ratios that are compared against bank tolerances. The loan indicators are total classified outstanding, total criticized outstanding, nonperforming loans, nonperforming assets, delinquencies and net loan losses. Due to the homogeneous nature of consumer loans, Trustmark does not assign a formal internal risk rating to each credit and therefore the criticized and classified measures are primarily composed of commercial loans. In addition to monitoring portfolio credit quality indicators, Trustmark also measures how effectively the lending process is being managed and risks are being identified. As part of an ongoing monitoring process, Trustmark grades the commercial portfolio segment as it relates to credit file completion and financial statement exceptions, underwriting, collateral documentation and compliance with law as shown below: • Credit File Completeness and Financial Statement Exceptions – evaluates the quality and condition of credit files in terms of content and completeness and focuses on efforts to obtain and document sufficient information to determine the quality and status of credits. Also included is an evaluation of the systems/procedures used to ensure compliance with policy. • Underwriting – evaluates whether credits are adequately analyzed, appropriately structured and properly approved within loan policy requirements. A properly approved credit is approved by adequate authority in a timely manner with all conditions of approval fulfilled. Total policy exceptions measure the level of underwriting and other policy exceptions within a portfolio segment. • Collateral Documentation – focuses on the adequacy of documentation to perfect Trustmark’s collateral position and substantiate collateral value. Collateral exceptions measure the level of documentation exceptions within a portfolio segment. Collateral exceptions occur when certain collateral documentation is either not present or not current. • Compliance with Law – focuses on underwriting, documentation, approval and reporting in compliance with banking laws and regulations. Primary emphasis is directed to the Financial Institutions Reform, Recovery and Enforcement Act of 1989 (FIRREA), Regulation O requirements and regulations governing appraisals. Commercial Credits Trustmark has established a loan grading system that consists of ten individual credit risk grades (risk ratings) that encompass a range from loans where the expectation of loss is negligible to loans where loss has been established. The model is based on the risk of default for an individual credit and establishes certain criteria to delineate the level of risk across the ten unique credit risk grades. Credit risk grade definitions are as follows: • Risk Rate (RR) 1 through RR 6 – Grades one through six represent groups of loans that are not subject to criticism as defined in regulatory guidance. Loans in these groups exhibit characteristics that represent low to moderate risk measured by using a variety of credit risk criteria such as cash flow coverage, debt service coverage, balance sheet leverage, liquidity, management experience, industry position, prevailing economic conditions, support from secondary sources of repayment and other credit factors that may be relevant to a specific loan. In general, these loans are supported by properly margined collateral and guarantees of principal parties. • Other Assets Especially Mentioned (Special Mention) (RR 7) – a loan that has a potential weakness that if not corrected will lead to a more severe rating. This rating is for credits that are currently protected but potentially weak because of an adverse feature or condition that if not corrected will lead to a further downgrade. • Substandard (RR 8) – a loan that has at least one identified weakness that is well defined. This rating is for credits where the primary sources of repayment are not viable at the time of evaluation or where either the capital or collateral is not adequate to support the loan and the secondary means of repayment do not provide a sufficient level of support to offset the identified weakness. Loss potential exists in the aggregate amount of substandard loans but does not necessarily exist in individual loans. • Doubtful (RR 9) – a loan with an identified weakness that does not have a valid secondary source of repayment. Generally, these credits have an impaired primary source of repayment and secondary sources are not sufficient to prevent a loss in the credit. The exact amount of the loss has not been determined at this time. • Loss (RR 10) – a loan or a portion of a loan that is deemed to be uncollectible. By definition, credit risk grades special mention (RR 7), substandard (RR 8), doubtful (RR 9) and loss (RR 10) are criticized loans while substandard (RR 8), doubtful (RR 9) and loss (RR 10) are classified loans. These definitions are standardized by all bank regulatory agencies and are generally equally applied by each individual lending institution. The remaining credit risk grades are considered pass credits and are solely defined by Trustmark. To enhance this process, Trustmark has determined that certain loans will be individually assessed, and a formal analysis will be performed and based upon the analysis the loan will be written down to the net realizable value. Trustmark will individually assess and remove loans from the pool in the following circumstances: • Commercial nonaccrual loans with total exposure of $500 thousand (excluding those portions of the debt that are government guaranteed or are secured by Trustmark deposits or marketable securities) or more. • Any loan that is believed to not share similar risk characteristics with the rest of the pool will be individually assessed. Otherwise, the loan will be left within the pool based on the results of the assessment. • Commercial accruing loans deemed to be a modified loan to a borrower experiencing financial difficulty with total exposure of $500 thousand (excluding those portions of the debt that are government guaranteed or are secured by Trustmark deposits or marketable securities) or more. If the loan is believed to not share similar risk characteristics with the rest of the loan pool, the loan will be individually assessed. Otherwise, the loan will be left within the pool and monitored on an ongoing basis. Each loan officer assesses the appropriateness of the internal risk rating assigned to their credits on an ongoing basis. Trustmark’s Asset Review area conducts independent credit quality reviews of the majority of Trustmark’s commercial loan portfolio both on the underlying credit quality of each individual loan class as well as the adherence to Trustmark’s loan policy and the loan administration process. In addition to the ongoing internal risk rate monitoring described above, Trustmark’s Credit Quality Review Committee meets monthly and performs a review of all loans of $100 thousand or more that are either delinquent 30 days or more or on nonaccrual. This review includes recommendations regarding risk ratings, accrual status, charge-offs and appropriate servicing officer as well as evaluation of problem credits for determination of modified status. Quarterly, the Credit Quality Review Committee reviews and modifies continuous action plans for all credits risk rated seven or worse for relationships of $250 thousand or more. In addition, periodic reviews of significant development, construction, multi-family, nonowner-occupied and other commercial credits are performed. These reviews assess each particular project with respect to location, project valuations, progress of completion, leasing status, current financial information, rents, operating expenses, cash flow, adherence to budget and projections and other information that is pertinent to the particular type of credit as applicable. Summary results are reviewed by Senior and Regional Credit Officers in addition to the Chief Credit Officer with a determination made as to the appropriateness of existing risk ratings and accrual status. Consumer Credits The Retail Credit Review Committee, Management Credit Policy Committee and the Enterprise Risk Committee review the volume and percentage of consumer loan delinquencies and losses to monitor the overall quality of the consumer portfolio. Trustmark monitors the levels and severity of past due consumer LHFI on a daily basis through its collection activities. A detailed assessment of consumer LHFI delinquencies is performed monthly at both a product and market level. The tables below present the amortized cost basis of loans by credit quality indicator and class of loans based on analyses performed at December 31, 2024 and 2023 ($ in thousands):
Past Due LHFS LHFS past due 90 days or more totaled $71.3 million and $51.2 million at December 31, 2024 and 2023, respectively. Trustmark did not exercise its buy-back option on any delinquent loans serviced for GNMA during 2024 or 2023. ACL, LHFI Trustmark’s ACL methodology for LHFI is based upon guidance within FASB ASC Subtopic 326-20 as well as applicable regulatory guidance. The ACL is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans. Credit quality within the LHFI portfolio is continuously monitored by Management and is reflected within the ACL for LHFI. The ACL is an estimate of expected losses inherent within Trustmark’s existing LHFI portfolio. The ACL for LHFI is adjusted through the PCL, LHFI and reduced by the charge off of loan amounts, net of recoveries. The methodology for estimating the amount of expected credit losses reported in the ACL has two basic components: a collective, or pooled, component for estimated expected credit losses for pools of loans that share similar risk characteristics, and an asset-specific component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans. In estimating the ACL for the collective component, loans are segregated into loan pools based on loan product types and similar risk characteristics. The loans secured by real estate and other loans secured by real estate portfolio segments include loans for both commercial and residential properties. The underwriting process for these loans includes analysis of the financial position and strength of both the borrower and guarantor, experience with similar projects in the past, market demand and prospects for successful completion of the proposed project within the established budget and schedule, values of underlying collateral, availability of permanent financing, maximum loan-to-value ratios, minimum equity requirements, acceptable amortization periods and minimum debt service coverage requirements, based on property type. The borrower’s financial strength and capacity to repay their obligations remain the primary focus of underwriting. Financial strength is evaluated based upon analytical tools that consider historical and projected cash flows and performance in addition to analysis of the proposed project for income-producing properties. Additional support offered by guarantors is also considered. Ultimate repayment of these loans is sensitive to interest rate changes, general economic conditions, liquidity and availability of long-term financing.
The commercial and industrial LHFI portfolio segment includes loans within Trustmark’s geographic markets made to many types of businesses for various purposes, such as short-term working capital loans that are usually secured by accounts receivable and inventory and term financing for equipment and fixed asset purchases that are secured by those assets. Trustmark’s credit underwriting process for commercial and industrial loans includes analysis of historical and projected cash flows and performance, evaluation of financial strength of both borrowers and guarantors as reflected in current and detailed financial information and evaluation of underlying collateral to support the credit.
The consumer LHFI portfolio segment is comprised of loans that are centrally underwritten based on the borrower's credit bureau score as well as an evaluation of the borrower’s repayment capacity, credit, and collateral. Property appraisals are obtained to assist in evaluating collateral. Loan-to-value and debt-to-income ratios, loan amount, and lien position are also considered in assessing whether to originate a loan. These borrowers are particularly susceptible to downturns in economic trends such as conditions that negatively affect housing prices and demand and levels of unemployment.
The state and other political subdivision LHFI and the other commercial LHFI and leases portfolio segments primarily consist of loans to non-depository financial institutions, such as mortgage companies, finance companies and other financial intermediaries, loans to state and political subdivisions, and loans to non-profit and charitable organizations. These loans are underwritten based on the specific nature or purpose of the loan and underlying collateral with special consideration given to the specific source of repayment for the loan. The lease segment primarily consists of commercial equipment finance leases. Trustmark’s credit underwriting process for equipment finance leases includes analysis of historical and projected cash flows and performance, evaluation of financial strength of both borrowers and guarantors as reflected in current and detailed financial information and evaluation of underlying collateral to support the credit. During the first quarter of 2024 as part of Trustmark's ongoing model monitoring procedures the annual loss driver analysis was performed. The analysis resulted in changes in the loss drivers for all discounted cash-flow models along with changes in the loss drivers for the equipment and finance loans and leases model. These changes were a result of updating Trustmark's peer group and incorporating data through 2022 which led to more intuitive loss drivers. All models were validated by a third party before implementation. The following table provides a description of each of Trustmark’s portfolio segments, loan classes, loan pools and the ACL methodology and loss drivers at December 31, 2024:
The following table provides a description of each of Trustmark’s portfolio segments, loan classes, loan pools and the ACL methodology and loss drivers at December 31, 2023:
In general, Trustmark utilizes a DCF method to estimate the quantitative portion of the ACL for loan pools. The DCF model consists of two key components, a loss driver analysis (LDA) and a cash flow analysis. For loan pools utilizing the DCF methodology, multiple assumptions are in place, depending on the loan pool. A reasonable and supportable forecast is utilized for each loan pool by developing a LDA for each loan class. The LDA uses charge off data from Federal Financial Institutions Examination Council (FFIEC) reports to construct a periodic default rate (PDR). The PDR is decomposed into a PD. Regressions are run using the data for various macroeconomic variables in order to determine which ones correlate to Trustmark’s losses. These variables are then incorporated into the application to calculate a quarterly PD using a third-party baseline forecast. In addition to the PD, a LGD is derived using a method referred to as Frye Jacobs. The Frye Jacobs method is a mathematical formula that traces the relationship between LGD and PD over time and projects the LGD based on the levels of PD forecasts. This model approach is applicable to all pools within the construction, land development and other land, other secured by 1-4 family residential properties, secured by nonfarm, nonresidential properties and other real estate secured loan classes as well as consumer loans and other commercial loans. During 2022, Management elected to incorporate a methodology change related to the other construction pool. Components of this change include management utilizing an alternative LDA to support the PD and LGD assumptions necessary to apply a DCF methodology to the other construction pool. Fundamentally, this approach utilizes publicly reported default balances and leverages a generalized linear model (GLM) framework to estimate PD. Taken together, these differences allow for results to be scaled to be specific and directly applicable to the other construction segment. LGD is assumed to be a through-the-cycle constant based on the actual performance of Trustmark’s other construction segment. These assumptions are then input into the DCF model and used in conjunction with prepayment data to calculate the cash flows at the individual loan level. Previously, the other construction pool used the weighted average remaining maturity (WARM) method. Management believes this change is commensurate with the level of risk in the pool. For the commercial and industrial loans related pools, Trustmark uses its own PD and LGD data, instead of the macroeconomic variables and the Frye Jacobs method described above, to calculate the PD and LGD as there were no defensible macroeconomic variables that correlated to Trustmark’s losses. Trustmark utilizes a third-party Bond Default Study to derive the PD and LGD for the obligations of state and political subdivisions pool. Due to the lack of losses within this pool, no defensible macroeconomic factors were identified to correlate. The PD and LGD measures are used in conjunction with prepayment data as inputs into the DCF model to calculate the cash flows at the individual loan level. Contractual cash flows based on loan terms are adjusted for PD, LGD and prepayments to derive loss cash flows. These loss cash flows are discounted by the loan’s coupon rate to arrive at the discounted cash flow based quantitative loss. The prepayment studies are updated quarterly by a third-party for each applicable pool. An alternate method of estimating the ACL is used for certain loan pools due to specific characteristics of these loans. For the non-DCF pools, specifically, those using the WARM method, the remaining life is incorporated into the ACL quantitative calculation. During the second quarter of 2024, Trustmark executed a sale on a portfolio of 1-4 family mortgage loans that were at least three payments delinquent and/or nonaccrual at the time of selection. As a result of this sale, a credit mark was established for a sub-pool of the loans in the sale. Due to the lack of historical experience and the use of industry data for this sub-pool, management elected to use the credit mark for reserving purposes on a go forward basis for this sub-pool that meets the same credit criteria of being three payments delinquent and/or nonaccrual. All loans of the sub-pool that meet the above credit criteria will be removed from the 1-4 family residential properties pool and placed into a separate pool with the credit mark reserve applied to the total balance. Trustmark determined that reasonable and supportable forecasts could be made for a twelve-month period for all of its loan pools. To the extent the lives of the loans in the LHFI portfolio extend beyond this forecast period, Trustmark uses a reversion period of four quarters and reverts to the historical mean on a straight-line basis over the remaining life of the loans. The econometric models currently in production reflect segment or pool level sensitivities of PD to changes in macroeconomic variables. By measuring the relationship between defaults and changes in the economy, the quantitative reserve incorporates reasonable and supportable forecasts of future conditions that will affect the value of Trustmark’s assets, as required by FASB ASC Topic 326. Under stable forecasts, these linear regressions will reasonably predict a pool’s PD. However, due to such events as the COVID-19 pandemic, the macroeconomic variables used for reasonable and supportable forecasting can change rapidly. At the macroeconomic levels experienced during the COVID-19 pandemic, it was not clear that the models in production at that time would produce reasonably representative results since the models at that time were originally estimated using data beginning in 2004 through 2019. During this period, a traditional, albeit severe, economic recession occurred. Thus, econometric models are sensitive to similar future levels of PD. In order to prevent the econometric models from extrapolating beyond reasonable boundaries of their input variables, Trustmark chose to establish an upper and lower limit process when applying the periodic forecasts. In this way, Management will not rely upon unobserved and untested relationships in the setting of the quantitative reserve. This approach applies to all input variables, including: Southern Unemployment, National Unemployment, National Gross Domestic Product (GDP), National Home Price Index (HPI), National Commercial Real Estate (CRE) Price Index and the BBB 7-10 Year US Corporate Bond Index (CBI). The upper and lower limits are based on the distribution of the macroeconomic variable by selecting extreme percentiles at the upper and lower limits of the distribution, the 1st and 99th percentiles, respectively. These upper and lower limits are then used to calculate the PD for the forecast time period in which the forecasted values are outside of the upper and lower limit range. Additionally, when periods have a PD or LGD at or near zero as a result of the improving macroeconomic forecasts, Management implemented PD and LGD floors to account for the risk associated with each portfolio. The PD and LGD floors are based on Trustmark’s historical loss experience and applied at a portfolio level. Qualitative factors used in the ACL methodology include the following: • Lending policies and procedures • Economic conditions and concentrations of credit • Nature and volume of the portfolio • Performance trends • External factors While all these factors are incorporated into the overall methodology, only four are currently considered active at December 31, 2024: (i) economic conditions and concentrations of credit, (ii) nature and volume of the portfolio, (iii) performance trends and (iv) external factors. Two of Trustmark’s largest loan classes are the loans secured by nonfarm, nonresidential properties and the loans secured by other real estate. Trustmark elected to create a qualitative factor specifically for these loan classes which addresses changes in the economic conditions of metropolitan areas and applies additional pool level reserves. This qualitative factor is based on third-party market data and forecast trends and is updated quarterly as information is available, by market and by loan pool. Trustmark's current quantitative methodologies do not completely incorporate changes in credit quality. As a result, Trustmark utilizes the performance trends qualitative factor. This factor is based on migration analyses, that allocates additional ACL to non-pass/delinquent loans within each pool. In this way, Management believes the ACL will directly reflect changes in risk, based on the performance of the loans within a pool, whether declining or improving. The performance trends qualitative factor is estimated by properly segmenting loan pools into risk levels by risk rating for commercial credits and delinquency status for consumer credits. A migration analysis is then performed quarterly using a third-party software and the results for each risk level are compiled to calculate the historical PD average for each loan portfolio based on risk levels. This average historical PD rate is updated annually. For the mortgage portfolio, Trustmark uses an internal report to incorporate a roll rate method for the calculation of the PD rate. In addition to the PD rate for each portfolio, Management incorporates the quantitative rate and the k value derived from the Frye-Jacobs method to calculate a loss estimate that includes both PD and LGD. The quantitative rate is used to eliminate any additional reserve that the quantitative reserve already includes. Finally, the loss estimate rate is then applied to the total balances for each risk level for each portfolio to calculate a qualitative reserve. During 2022, Management elected to activate the nature and volume of the portfolio qualitative factor as a result of a sub-pool of the secured by 1-4 family residential properties growing to a significant size along with the underlying nature being different as well. The nature and volume of the portfolio qualitative factor utilizes a WARM methodology that uses industry data for the assumptions to support the qualitative adjustment. The industry data is used to compile a PD based on credit score ranges along with using the industry data to compile an LGD. The sub-pool of credits is then aggregated into the appropriate credit score bands in which a weighted average loss rate is calculated based on the PD and LGD for each credit score range. This weighted average loss rate is then applied to the expected balance for the sub-segment of credits. This total is then used as the qualitative reserve adjustment. The external factors qualitative factor is Management’s best judgment on the loan or pool level impact of all factors that affect the portfolio that are not accounted for using any other part of the ACL methodology (e.g., natural disasters, changes in legislation, impacts due to technology and pandemics). During the third quarter of 2024, Trustmark activated the External Factor – Credit Quality Review qualitative factor. This qualitative factor ensures reserve adequacy for collectively evaluated commercial loans that may not have been identified and downgraded timely for various reasons. This qualitative factor population is all commercial loans risk rated 1-5. These loans are then applied to the historical average of the Watch/Special Mention rated percentage. Then the balance of these loans are applied additional reserves based on the same reserve rates utilized in the performance trends qualitative factor for Watch/Special Mention rated loans. Then the Watch/Special Mention population is applied the historical Substandard rated percentage and then subsequently applied the Substandard reserve rate utilized in the performance trends qualitative factor as well. The historical Watch/Special Mention and Substandard rated percentage averages captures the weighted average life of the commercial loan portfolio. Thus, Trustmark will allocate additional reserves to capture the proportion of potential Watch/Special Mention and Substandard rated credits that may not have been categorized as such at any given point in time through the life of the commercial loan portfolio. The following tables disaggregate the ACL, LHFI and the amortized cost basis of the loans by the measurement methodology used at December 31, 2024 and 2023 ($ in thousands):
Changes in the ACL, LHFI were as follows for the periods presented ($ in thousands):
The following tables detail changes in the ACL, LHFI by loan class for the years ended December 31, 2024 and 2023 ($ in thousands):
The PCL, LHFI for the year ended December 31, 2024 was primarily attributable to loan growth, changes in the macroeconomic forecast, an increase in specific reserves on individually analyzed credits and net adjustments to the qualitative factors.
The negative PCL, LHFI for the construction, land development and other land portfolio and other secured by 1-4 family residential properties portfolio for the year ended December 31, 2024 was primarily due to changes in the macroeconomic forecast associated with these specific loss driver models as a result of the loss driver update for these loan portfolios. The negative PCL, LHFI for the other commercial loans and leases portfolio for the year ended December 31, 2024 was primarily due to a decrease in loan balances.
The PCL, LHFI for the year ended December 31, 2023 was primarily attributable to loan growth, extended maturities on the secured by 1-4 family residential properties resulting from lower prepayment speeds, changes in the macroeconomic forecast and net adjustments to the qualitative factors. The negative PCL, LHFI for the other construction portfolio for the year ended December 31, 2023 was primarily due to the transfer of a fully-reserved nonaccrual loan to other real estate, net. |

| Mortgage Banking | Note 7 – Mortgage Banking MSR The activity in the MSR is detailed in the table below for the periods presented ($ in thousands):
Trustmark determines the fair value of the MSR using a valuation model administered by a third party that calculates the present value of estimated future net servicing income. Trustmark considers the conditional prepayment rate (CPR), which is an estimated loan prepayment rate that uses historical prepayment rates for previous loans similar to the loans being evaluated, the float rate, which is the interest rate earned on escrow balances, and the discount rate as some of the primary assumptions used in determining the fair value of the MSR. An increase in either the CPR or discount rate assumption will result in a decrease in the fair value of the MSR, while a decrease in either assumption will result in an increase in the fair value of the MSR. An increase in the float rate will result in an increase in the fair value of the MSR, while a decrease in the float rate will result in a decrease in the fair value of the MSR. At December 31, 2024, the fair value of the MSR included an assumed average prepayment speed of 8 CPR and an average discount rate of 10.65% compared to an assumed average prepayment speed of 9 CPR and an average discount rate of 10.07% at December 31, 2023. Mortgage Loans Sold/Serviced During 2024, 2023 and 2022, Trustmark sold $1.141 billion, $1.136 billion and $1.243 billion, respectively, of residential mortgage loans. Gain on sales of loans, net totaled $19.3 million in 2024, $15.3 million in 2023 and $20.2 million in 2022. Trustmark receives annual servicing fee income approximating 0.32% of the outstanding balance of the underlying loans, which totaled $28.0 million in 2024, $26.9 million in 2023 and $26.0 million in 2022. The gains on the sale of residential mortgage loans and the annual servicing fee are both recorded to noninterest income in mortgage banking, net in the accompanying consolidated statements of income. The investors and the securitization trusts have no recourse to the assets of Trustmark for failure of debtors to pay when due. The table below details the mortgage loans sold and serviced for others at December 31, 2024 and 2023 ($ in thousands):
Trustmark is subject to losses in its loan servicing portfolio due to loan foreclosures. Trustmark has obligations to either repurchase the outstanding principal balance of a loan or make the purchaser whole for the economic benefits of a loan if it is determined that the loan sold was in violation of representations or warranties made by Trustmark at the time of the sale, herein referred to as mortgage loan servicing putback expenses. Such representations and warranties typically include those made regarding loans that had missing or insufficient file documentation, loans that do not meet investor guidelines, loans in which the appraisal does not support the value and/or loans obtained through fraud by the borrowers or other third parties. Generally, putback requests may be made until the loan is paid in full. However, mortgage loans delivered to Federal National Mortgage Association (FNMA) and Federal Home Loan Mortgage Corporation (FHLMC) on or after January 1, 2013 are subject to the Representations and Warranties Framework, which provides certain instances in which FNMA and FHLMC will not exercise their remedies, including a putback request, for breaches of certain selling representations and warranties, such as payment history and quality control review. When a putback request is received, Trustmark evaluates the request and takes appropriate actions based on the nature of the request. Trustmark is required by FNMA and FHLMC to provide a response to putback requests within 60 days of the date of receipt. The total mortgage loan servicing putback expenses are included in other expense. At both December 31, 2024 and 2023, Trustmark had a reserve for mortgage loan servicing putback expenses of $500 thousand. There is inherent uncertainty in reasonably estimating the requirement for reserves against potential future mortgage loan servicing putback expenses. Future putback expenses are dependent on many subjective factors, including the review procedures of the purchasers and the potential refinance activity on loans sold with servicing released and the subsequent consequences under the representations and warranties. Trustmark believes that it has appropriately reserved for potential mortgage loan servicing putback requests. |

Trustmark’s General Banking Segment delivers a full range of banking services to consumer, corporate, small and middle-market businesses through its extensive branch network. Trustmark performed goodwill impairment tests for the General Banking Segment during 2024, 2023 and 2022. Based on these tests, Trustmark concluded that the fair value of the General Banking Segment exceeded the book value and no impairment charge was required. Identifiable Intangible Assets At December 31, 2024 and 2023, identifiable intangible assets consisted of the following ($ in thousands):
Trustmark recorded $110 thousand of amortization of identifiable intangible assets in 2024, $290 thousand in 2023 and $985 thousand in 2022. Trustmark estimates that amortization expense for identifiable intangible assets will be $126 thousand in 2025 and none in the following years. Trustmark continually evaluates whether events and circumstances have occurred that indicate that identifiable intangible assets have become impaired. Measurement of any impairment of such identifiable intangible assets is based on the fair values of those assets. There were no impairment losses on identifiable intangible assets recorded during 2024, 2023 or 2022.

FHLB Advances At both December 31, 2024 and 2023, Trustmark had no outstanding short-term FHLB advances with the FHLB of Atlanta. At December 31, 2024, Trustmark had no outstanding long-term FHLB advances with the FHLB of Atlanta, compared to one outstanding long-term FHLB advance with the FHLB of Atlanta totaling $58 thousand at December 31, 2023. This advance was assumed through the BancTrust merger and had a fixed interest rate of 0.08%. At December 31, 2023, this advance had a remaining maturity of 2.71 years. There was no fair market value adjustment associated with the BancTrust merger included in the FHLB advances at December 31, 2023. Trustmark’s FHLB advance was collateralized by securities held in safekeeping with the FHLB of Atlanta. At December 31, 2024, Trustmark had two outstanding short-term FHLB advances totaling $200.0 million and no long-term FHLB advances with the FHLB of Dallas, compared to five outstanding short-term FHLB advances totaling $400.0 million and no long-term FHLB advances with the FHLB of Dallas at December 31, 2023. The outstanding short-term advances with the FHLB of Dallas at December 31, 2024 had fixed rates of 4.55% and 4.65% with balances of $100.0 million each. The outstanding short-term FHLB advances had a weighted-average remaining maturity of 8 days with a weighted-average cost of 4.60% at December 31, 2024, compared to a weighted-average remaining maturity of 9 days with a weighted-average cost of 5.54% at December 31, 2023. Trustmark incurred $16.8 million of interest expense on short-term FHLB advances in 2024, compared to $49.9 million of interest expense in 2023 and $4.8 million of interest expense in 2022. Trustmark incurred no interest expense on long-term FHLB advances in 2024, 2023 and 2022. At December 31, 2024 and 2023, Trustmark had $4.292 billion and $4.003 billion, respectively, available in additional borrowing capacity from the FHLB of Dallas. Subordinated Notes During 2020, Trustmark agreed to issue and sell $125.0 million aggregate principal amount of its 3.625% Fixed-to-Floating Rate Subordinated Notes (the Notes) due December 1, 2030. The Notes were sold at an underwriting discount of 1.2%, resulting in net proceeds to Trustmark of $123.5 million before deducting offering expenses. At December 31, 2024 and 2023, the carrying amount of the Notes was $123.7 million and $123.5 million, respectively. The Notes are unsecured obligations and are subordinated in right of payment to all of Trustmark’s existing and future senior indebtedness, whether secured or unsecured. The Notes are obligations of Trustmark only and are not obligations of, and are not guaranteed by, any of its subsidiaries, including TNB. From the date of issuance until November 30, 2025, the Notes bear interest at a fixed rate of 3.625% per year, payable semi-annually in arrears on June 1 and December 1 of each year. Beginning December 1, 2025, the Notes will bear interest at a floating rate per year equal to the Benchmark rate, which is the Three-Month Term Secured Overnight Financing Rate (SOFR), plus 338.7 basis points, payable quarterly in arrears on March 1, June 1, September 1 and December 1 of each year. The Notes qualify as Tier 2 capital for Trustmark. The Notes may be redeemed at Trustmark’s option under certain circumstances. Trustmark intends to use the net proceeds for general corporate purposes. Junior Subordinated Debt Securities On August 18, 2006, Trustmark completed a private placement of $60.0 million of trust preferred securities through a newly formed Delaware trust affiliate, Trustmark Preferred Capital Trust I (the Trust). The trust preferred securities mature September 30, 2036, are redeemable at Trustmark’s option and bear interest at a variable rate per annum equal to the three-month Chicago Mercantile Exchange, Inc. (CME) SOFR plus a spread adjustment of 0.26% and a margin of 1.72%. Under applicable regulatory guidelines, these trust preferred securities qualify as Tier 1 capital. The proceeds from the sale of the trust preferred securities were used by the Trust to purchase $61.9 million in aggregate principal amount of Trustmark’s junior subordinated debentures. The debentures were issued pursuant to a Junior Subordinated Indenture, dated August 18, 2006, between Trustmark, as issuer, and Wilmington Trust Company, National Association, as trustee. Like the trust preferred securities, the debentures bear interest at a variable rate per annum equal to the three-month CME SOFR plus a spread adjustment of 0.26% and a margin of 1.72% and mature on September 30, 2036. The debentures may be redeemed at Trustmark’s option at any time. The interest payments by Trustmark will be used to pay the quarterly distributions payable by the Trust to the holder of the trust preferred securities. However, so long as no event of default has occurred under the debentures, Trustmark may defer interest payments on the debentures (in which case the Trust will also defer distributions otherwise due on the trust preferred securities) for up to 20 consecutive quarters. The debentures are subordinated to the prior payment of any other indebtedness of Trustmark that, by its terms, is not similarly subordinated. The trust preferred securities are recorded as a long-term liability on Trustmark’s balance sheet; however, for regulatory purposes the trust preferred securities are treated as Tier 1 capital under the rules of the Federal Reserve Board (FRB), Trustmark’s primary federal regulatory agency. Trustmark also entered into a Guarantee Agreement, dated August 18, 2006, pursuant to which it has agreed to guarantee the payment by the Trust of distributions on the trust preferred securities and the payment of principal of the trust preferred securities when due, either at maturity or on redemption, but only if and to the extent that the Trust fails to pay distributions on or principal of the trust preferred securities after having received interest payments or principal payments on the junior subordinated debentures from Trustmark for the purpose of paying those distributions or the principal amount of the trust preferred securities. As defined in applicable accounting standards, the Trust, a wholly-owned subsidiary of Trustmark, is considered a variable interest entity for which Trustmark is not the primary beneficiary. Accordingly, the accounts of the Trust are not included in Trustmark’s consolidated financial statements. At both December 31, 2024 and 2023, assets for the Trust totaled $61.9 million, resulting from the investment in junior subordinated debentures issued by Trustmark. Liabilities and shareholders’ equity for the Trust also totaled $61.9 million at both December 31, 2024 and 2023, resulting from the issuance of trust preferred securities in the amount of $60.0 million as well as $1.9 million in common securities issued to Trustmark. During 2024, net income for the Trust equaled $134 thousand resulting from interest income from the junior subordinated debt securities issued by Trustmark to the Trust, compared with net income of $132 thousand during 2023 and $66 thousand during 2022. Dividends issued to Trustmark by the Trust during 2024 totaled $134 thousand, compared to $132 thousand during 2023 and $66 thousand during 2022. |

| Defined Benefit and Other Postretirement Benefits | Note 15 – Defined Benefit and Other Postretirement Benefits Qualified Pension Plan Trustmark maintains a noncontributory tax-qualified defined benefit pension plan titled the Trustmark Corporation Pension Plan for Certain Employees of Acquired Financial Institutions (the Continuing Plan) to satisfy commitments made by Trustmark to associates covered through plans obtained in acquisitions. The following tables present information regarding the benefit obligation, plan assets, funded status, amounts recognized in accumulated other comprehensive loss, net periodic benefit cost and other statistical disclosures for the Continuing Plan for the periods presented ($ in thousands):
Plan Assets The weighted-average asset allocations by asset category are presented below for the Continuing Plan at December 31, 2024 and 2023.
The strategic objective of the investments of the assets in the Continuing Plan aims to provide both income and potential capital appreciation. The allocation is managed on a total return basis with the average participant age in mind. It is well suited for moderately conservative investors seeking an ample level of income while also participating in equity markets. This investment mix is designed to take advantage of rising stock markets while cushioning the effects of stock market downturns. The portfolio is typically balanced between equity and fixed income. The equity exposure has the potential to earn a return greater than inflation while the fixed income exposure may reduce the risk and volatility of the portfolio to which the equity mutual funds contribute. Fair Value Measurements At this time, Trustmark presents no fair values that are derived through internal modeling. Should positions requiring fair valuation arise that are not relevant to existing methodologies, Trustmark will make every reasonable effort to obtain market participant assumptions, or independent evaluation. The following tables set forth by level, within the fair value hierarchy, the Continuing Plan’s assets measured at fair value at December 31, 2024 and 2023 ($ in thousands):
There have been no changes in the methodologies used in estimating the fair value of plan assets at December 31, 2024. The money market fund approximates fair value due to its immediate maturity. The preceding methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although Trustmark believes their valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. Contributions The range of potential contributions to the Continuing Plan is determined annually by the Continuing Plan’s actuary in accordance with applicable IRS rules and regulations. Trustmark’s policy is to fund amounts that are sufficient to satisfy the annual minimum funding requirements and do not exceed the maximum that is deductible for federal income tax purposes. The actual amount of the contribution is determined annually based on the Continuing Plan’s funded status and return on plan assets as of the measurement date, which is December 31. For the plan year ending December 31, 2024, Trustmark’s minimum required contribution to the Continuing Plan was $127 thousand and Trustmark contributed $290 thousand. For the plan year ending December 31, 2025, Trustmark’s minimum required contribution to the Continuing Plan is expected to be $109 thousand. Management and the Board of Directors of Trustmark will monitor the Continuing Plan throughout 2025 to determine any additional funding requirements by the plan’s measurement date. Estimated Future Benefit Payments and Other Disclosures The following table presents the expected benefit payments, which reflect expected future service, for the Continuing Plan ($ in thousands):
Amounts in accumulated other comprehensive income (loss) expected to be recognized as components of net periodic benefit cost during 2025 include a gain of $7 thousand. Supplemental Retirement Plans Trustmark maintains a nonqualified supplemental retirement plan covering key executive officers and senior officers as well as directors who have elected to defer fees. The plan provides for retirement and/or death benefits based on a participant’s covered salary or deferred fees. Although plan benefits may be paid from Trustmark’s general assets, Trustmark has purchased life insurance contracts on the participants covered under the plan, which may be used to fund future benefit payments under the plan. The annual measurement date for the plan is December 31. As a result of mergers prior to 2014, Trustmark became the administrator of nonqualified supplemental retirement plans, for which the plan benefits were frozen prior to the merger date. The following tables present information regarding the benefit obligation, plan assets, funded status, amounts recognized in accumulated other comprehensive loss, net periodic benefit cost and other statistical disclosures for Trustmark’s nonqualified supplemental retirement plans for the periods presented ($ in thousands):
Estimated Supplemental Retirement Plan Payments and Other Disclosures The following table presents the expected benefits payments for Trustmark’s supplemental retirement plans ($ in thousands):
Amounts in accumulated other comprehensive income (loss) expected to be recognized as components of net periodic benefit cost during 2025 include a loss of $261 thousand and prior service cost of $15 thousand. Other Benefit Plans Defined Contribution Plan Trustmark provides associates with a self-directed 401(k) retirement plan that allows associates to contribute a percentage of eligible compensation, within limits provided by the Internal Revenue Code and accompanying regulations, into the plan. Trustmark matches 100% of associate contributions to the plan based on the amount of each participant’s contributions up to a maximum of 6% of eligible compensation, subject to the IRS maximum eligible compensation. Associates are automatically enrolled in the plan at 3% of eligible compensation unless they opt out within 60 days of employment. Associates may become eligible to make elective deferral contributions the first of the month following one month of employment. Eligible associates that elect to participate vest immediately in Trustmark’s matching contributions, as this is a Safe Harbor 401(k) Plan. Trustmark’s contributions to this plan were $10.7 million in 2024, $10.8 million in 2023 and $10.2 million in 2022. |

| Stock and Incentive Compensation Plans | Note 16 – Stock and Incentive Compensation Plans Trustmark has granted restricted stock units subject to the provisions of the Stock and Incentive Compensation Plan (the Stock Plan). Current outstanding and future grants of restricted stock units are subject to the provisions of the Stock Plan, which is designed to provide flexibility to Trustmark regarding its ability to motivate, attract and retain the services of key associates and directors. The Stock Plan also allows Trustmark to grant nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock, restricted stock units and performance units to key associates and directors. At December 31, 2024, the maximum number of shares of Trustmark’s common stock available for issuance under the Stock Plan was 849,968 shares. Restricted Stock Grants Performance Units Trustmark’s performance units vest over three years and are granted to Trustmark’s executive and senior management teams. Performance units granted vest based on performance goals of return on average tangible equity and total shareholder return. Performance units are valued utilizing a Monte Carlo simulation model to estimate fair value of the units at the grant date. The Monte Carlo simulation is performed by an independent valuation consultant and requires the use of subjective modeling assumptions. These units are recognized using the straight-line method over the requisite service period. These units are granted at 100% of target, yet provide for achievement units if performance measures exceed 100%. The restricted stock agreement for these units provide for dividend privileges, but no voting rights. The following table summarizes Trustmark’s performance unit activity for the periods presented:

| Commitments and Contingencies Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Commitments and Contingencies | Note 17 – Commitments and Contingencies Lending Related Trustmark makes commitments to extend credit and issues standby and commercial letters of credit (letters of credit) in the normal course of business in order to fulfill the financing needs of its customers. The carrying amount of commitments to extend credit and letters of credit approximates the fair value of such financial instruments. Commitments to extend credit are agreements to lend money to customers pursuant to certain specified conditions. Commitments generally have fixed expiration dates or other termination clauses. Because many of these commitments are expected to expire without being fully drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The exposure to credit loss in the event of nonperformance by the other party to the commitments to extend credit is represented by the contract amount of those instruments. Trustmark applies the same credit policies and standards as it does in the lending process when making these commitments. The collateral obtained is based upon the nature of the transaction and the assessed creditworthiness of the borrower. At December 31, 2024 and 2023, Trustmark had unused commitments to extend credit of $4.575 billion and $4.907 billion, respectively. Letters of credit are conditional commitments issued by Trustmark to insure the performance of a customer to a third-party. A financial standby letter of credit irrevocably obligates Trustmark to pay a third-party beneficiary when a customer fails to repay an outstanding loan or debt instrument. A performance standby letter of credit irrevocably obligates Trustmark to pay a third-party beneficiary when a customer fails to perform some contractual, nonfinancial obligation. When issuing letters of credit, Trustmark uses the same policies regarding credit risk and collateral, which are followed in the lending process. At December 31, 2024 and 2023, Trustmark’s maximum exposure to credit loss in the event of nonperformance by the other party for letters of credit was $110.4 million and $125.4 million, respectively. These amounts consist primarily of commitments with maturities of less than three years, which have an immaterial carrying value. Trustmark holds collateral to support standby letters of credit when deemed necessary. At December 31, 2024 and 2023, the fair value of collateral held was $27.2 million and $31.4 million, respectively. ACL on Off-Balance Sheet Credit Exposures Trustmark maintains a separate ACL on off-balance sheet credit exposures, including unfunded loan commitments and letters of credit, which is included on the accompanying consolidated balance sheets. Changes in the ACL on off-balance sheet credit exposures were as follows for the periods presented ($ in thousands):
Adjustments to the ACL on off-balance sheet credit exposures are recorded to PCL, off-balance sheet credit exposures. The decrease in the ACL on off-balance sheet credit exposures for the year ended December 31, 2024 primarily reflected a decrease in required reserves as a result of changes in the total reserve rate coupled with a decrease in unfunded commitments which was partially offset by an increase in required reserves as a result of implementing the Performance Trend and the External Factor-Credit Quality Review qualitative reserve factors. The decrease in the ACL on off-balance sheet credit exposures for the year ended December 31, 2023 was primarily due to decreases in unfunded commitments for the construction, land development and other land portfolio and other construction loan portfolio. Legal Proceedings Trustmark and its subsidiaries are parties to lawsuits and other claims that arise in the ordinary course of business. Some of the lawsuits assert claims related to the lending, collection, servicing, investment, trust and other business activities, and some of the lawsuits allege substantial claims for damages. In accordance with FASB ASC Subtopic 450-20, “Loss Contingencies,” Trustmark will establish an accrued liability for any litigation matter if and when such matter presents loss contingencies that are both probable and reasonably estimable. At the present time, Trustmark believes, based on its evaluation and the advice of legal counsel, that a loss in any currently pending legal proceeding is not probable and a reasonable estimate cannot reasonably be made. |

| Shareholders' Equity | Note 18 – Shareholders’ Equity Regulatory Capital Trustmark and TNB are subject to minimum risk-based capital and leverage capital requirements, as described in the section captioned “Capital Adequacy” included in Part I. Item 1. – Business of this report, which are administered by the federal bank regulatory agencies. These capital requirements, as defined by federal regulations, involve quantitative and qualitative measures of assets, liabilities and certain off-balance sheet instruments. Trustmark’s and TNB’s minimum risk-based capital requirements include a capital conservation buffer of 2.5%. Accumulated other comprehensive income (loss), net of tax, is not included in computing regulatory capital.

Failure to meet minimum capital requirements can result in certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the financial statements of Trustmark and TNB and limit Trustmark’s and TNB’s ability to pay dividends. At December 31, 2024, Trustmark and TNB exceeded all applicable minimum capital standards. In addition, Trustmark and TNB met applicable regulatory guidelines to be considered well-capitalized at December 31, 2024. To be categorized in this manner, Trustmark and TNB maintained minimum common equity Tier 1 risk-based capital, Tier 1 risk-based capital, total risk-based capital and Tier 1 leverage ratios as set forth in the accompanying table, and were not subject to any written agreement, order or capital directive, or prompt corrective action directive issued by their primary federal regulators to meet and maintain a specific capital level for any capital measures. There are no significant conditions or events that have occurred since December 31, 2024, which Management believes have affected Trustmark’s or TNB’s present classification. The following table provides Trustmark’s and TNB’s actual regulatory capital amounts and ratios under regulatory capital standards in effect at December 31, 2024 and 2023 ($ in thousands):
Dividends on Common Stock Dividends paid by Trustmark are substantially funded from dividends received from TNB. Approval by TNB’s regulators is required if the total of all dividends declared in any calendar year exceeds the total of its net income for that year combined with its retained net income of the preceding two years. In 2025, TNB will have available approximately $255.3 million plus its net income for that year to pay as dividends. Stock Repurchase Program On December 7, 2021, Trustmark’s Board of Directors authorized a stock repurchase program effective January 1, 2022, under which $100.0 million of Trustmark’s outstanding shares could be acquired through December 31, 2022. Under this authority, Trustmark repurchased approximately 789 thousand shares of its common stock valued at $24.6 million during the twelve months ended December 31, 2022. On December 6, 2022, Trustmark’s Board of Directors authorized a stock repurchase program effective January 1, 2023, under which $50.0 million of Trustmark’s outstanding shares could be acquired through December 31, 2023. No shares were repurchased under this stock repurchase program. On December 5, 2023, Trustmark’s Board of Directors authorized a stock repurchase program effective January 1, 2024, under which $50.0 million of Trustmark’s outstanding shares could be acquired through December 31, 2024. Under this authority, Trustmark repurchased approximately 203 thousand shares of its common stock valued at $7.5 million during the twelve months ended December 31, 2024. On December 3, 2024, Trustmark’s Board of Directors authorized a stock repurchase program effective January 1, 2025, under which $100.0 million of Trustmark’s outstanding shares may be acquired through December 31, 2025. The repurchase program, which is subject to market conditions and management discretion, will be implemented through open market repurchases or privately negotiated transactions. Under this authority, Trustmark repurchased approximately 243 thousand shares of its common stock valued at $8.5 million during January 2025. Other Comprehensive Income (Loss) and Accumulated Other Comprehensive Income (Loss) The following tables present the net change in the components of accumulated other comprehensive income (loss) and the related tax effects allocated to each component for the years ended December 31, 2024, 2023 and 2022 ($ in thousands). The amortization of prior service cost, recognized net loss due to lump sum settlements and change in net actuarial loss are included in the computation of net periodic benefit cost (see Note 15 – Defined Benefit and Other Postretirement Benefits for additional details). Reclassification adjustments related to pension and other postretirement benefit plans are included in salaries and employee benefits and other expense in the accompanying consolidated statements of income. Reclassification adjustments related to the cash flow hedge derivatives are included in interest and fees on LHFS and LHFI in the accompanying consolidated statements of income.
The following table presents the changes in the balances of each component of accumulated other comprehensive income (loss) for the periods presented ($ in thousands). All amounts are presented net of tax.

| Fair Value | Note 19 – Fair Value Financial Instruments Measured at Fair Value The methodologies Trustmark uses in determining the fair values are based primarily on the use of independent, market-based data to reflect a value that would be reasonably expected upon exchange of the position in an orderly transaction between market participants at the measurement date. The predominant portion of assets that are stated at fair value are of a nature that can be valued using prices or inputs that are readily observable through a variety of independent data providers. The providers selected by Trustmark for fair valuation data are widely recognized and accepted vendors whose evaluations support the pricing functions of financial institutions, investment and mutual funds, and portfolio managers. Trustmark has documented and evaluated the pricing methodologies used by the vendors and maintains internal processes that regularly test valuations for anomalies. Trustmark utilizes an independent pricing service to advise it on the carrying value of the securities available for sale portfolio. As part of Trustmark’s procedures, the price provided from the service is evaluated for reasonableness given market changes. When a questionable price exists, Trustmark investigates further to determine if the price is valid. If needed, other market participants may be utilized to determine the correct fair value. Trustmark has also reviewed and confirmed its determinations in thorough discussions with the pricing source regarding their methods of price discovery. Mortgage loan commitments are valued based on the securities prices of similar collateral, term, rate and delivery for which the loan is eligible to deliver in place of the particular security. Trustmark acquires a broad array of mortgage security prices that are supplied by a market data vendor, which in turn accumulates prices from a broad list of securities dealers. Prices are processed through a mortgage pipeline management system that accumulates and segregates all loan commitment and forward-sale transactions according to the similarity of various characteristics (maturity, term, rate, and collateral). Prices are matched to those positions that are deemed to be an eligible substitute or offset (i.e., “deliverable”) for a corresponding security observed in the marketplace. Trustmark estimates fair value of the MSR through the use of prevailing market participant assumptions and market participant valuation processes. This valuation is periodically tested and validated against other third-party firm valuations. Trustmark obtains the fair value of interest rate swaps from a third-party pricing service that uses an industry standard discounted cash flow methodology. In addition, credit valuation adjustments are incorporated in the fair values to account for potential nonperformance risk. In adjusting the fair value of its interest rate swap contracts for the effect of nonperformance risk, Trustmark has considered any applicable credit enhancements such as collateral postings, thresholds, mutual puts, and guarantees. In conjunction with the FASB’s fair value measurement guidance, Trustmark made an accounting policy election to measure the credit risk of these derivative financial instruments, which are subject to master netting agreements, on a net basis by counterparty portfolio. Trustmark has determined that the majority of the inputs used to value its interest rate swaps offered to qualified commercial borrowers fall within Level 2 of the fair value hierarchy, while the credit valuation adjustments associated with these derivatives utilize Level 3 inputs, such as estimates of current credit spreads. Trustmark has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its interest rate swaps and has determined that the credit valuation adjustment is not significant to the overall valuation of these derivatives. As a result, Trustmark classifies its interest rate swap valuations in Level 2 of the fair value hierarchy. Trustmark also utilizes exchange-traded derivative instruments such as Treasury note futures contracts and option contracts to achieve a fair value return that offsets the changes in fair value of the MSR attributable to interest rates. Fair values of these derivative instruments are determined from quoted prices in active markets for identical assets therefore allowing them to be classified within Level 1 of the fair value hierarchy. In addition, Trustmark utilizes derivative instruments such as interest rate lock commitments in its mortgage banking area which lack observable inputs for valuation purposes resulting in their inclusion in Level 3 of the fair value hierarchy. At this time, Trustmark presents no fair values that are derived through internal modeling. Should positions requiring fair valuation arise that are not relevant to existing methodologies, Trustmark will make every reasonable effort to obtain market participant assumptions, or independent evaluation. Financial Assets and Liabilities The following tables summarize financial assets and financial liabilities measured at fair value on a recurring basis at December 31, 2024 and 2023, segregated by the level of valuation inputs within the fair value hierarchy utilized to measure fair value ($ in thousands). There were no transfers between fair value levels for the years ended December 31, 2024 and 2023.
The changes in Level 3 assets measured at fair value on a recurring basis for the years ended December 31, 2024 and 2023 are summarized as follows ($ in thousands):
(1) Total net (loss) gain included in Mortgage banking, net relating to the MSR includes changes in fair value due to market changes and due to run-off. Trustmark may be required, from time to time, to measure certain assets at fair value on a nonrecurring basis in accordance with GAAP. Assets at December 31, 2024, which have been measured at fair value on a nonrecurring basis, include collateral-dependent LHFI. A loan is collateral dependent when the borrower is experiencing financial difficulty and repayment of the loan is expected to be provided substantially through the sale of the collateral. The expected credit loss for collateral-dependent loans is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral, adjusted for the estimated cost to sell. Fair value estimates for collateral-dependent loans are derived from appraised values based on the current market value or as is value of the collateral, normally from recently received and reviewed appraisals. Current appraisals are ordered on an annual basis based on the inspection date or more often if market conditions necessitate. Appraisals are obtained from state-certified appraisers and are based on certain assumptions, which may include construction or development status and the highest and best use of the property. These appraisals are reviewed by Trustmark’s Appraisal Review Department to ensure they are acceptable, and values are adjusted down for costs associated with asset disposal. At December 31, 2024, Trustmark had outstanding balances of $37.1 million with a related ACL of $13.7 million in collateral-dependent LHFI, compared to outstanding balances of $49.1 million with a related ACL of $12.4 million in collateral-dependent LHFI at December 31, 2023. The collateral-dependent LHFI are classified as Level 3 in the fair value hierarchy. Nonfinancial Assets and Liabilities Certain nonfinancial assets measured at fair value on a nonrecurring basis include foreclosed assets (upon initial recognition or subsequent impairment), nonfinancial assets and nonfinancial liabilities measured at fair value in the second step of a goodwill impairment test, and intangible assets and other nonfinancial long-lived assets measured at fair value for impairment assessment. Other real estate includes assets that have been acquired in satisfaction of debt through foreclosure and is recorded at the fair value less cost to sell (estimated fair value) at the time of foreclosure. Fair value is based on independent appraisals and other relevant factors. In the determination of fair value subsequent to foreclosure, Management also considers other factors or recent developments, such as changes in market conditions from the time of valuation and anticipated sales values considering plans for disposition, which could result in an adjustment to lower the collateral value estimates indicated in the appraisals. Periodic revaluations are classified as Level 3 in the fair value hierarchy since assumptions are used that may not be observable in the market. Foreclosed assets of $5.5 million were re-measured during 2024, requiring write-downs of $2.2 million to reach their current fair values compared to $898 thousand of foreclosed assets that were re-measured during 2023, requiring write-downs of $243 thousand. Fair Value of Financial Instruments FASB ASC Topic 825 requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis. The carrying amounts and estimated fair values of financial instruments at December 31, 2024 and 2023 were as follows ($ in thousands):
Fair Value Option Trustmark has elected to account for its LHFS under the fair value option, with interest income on these LHFS reported in interest and fees on LHFS and LHFI. The fair value of the LHFS is determined using quoted prices for a similar asset, adjusted for specific attributes of that loan. The LHFS are actively managed and monitored and certain market risks of the loans may be mitigated through the use of derivatives. These derivative instruments are carried at fair value with changes in fair value recorded as noninterest income in mortgage banking, net. The changes in the fair value of the LHFS are largely offset by changes in the fair value of the derivative instruments. For the year ended December 31, 2024, a net loss of $2.1 million was recorded as noninterest income in mortgage banking, net for changes in the fair value of the LHFS accounted for under the fair value option compared to net gain of $2.2 million and a net loss of $3.3 million, respectively, for the years ended December 31, 2023 and 2022. Interest and fees on LHFS and LHFI for the year ended December 31, 2024 included $8.6 million of interest earned on the LHFS accounted for under the fair value option compared to $7.8 million and $6.8 million for the years ended December 31, 2023 and 2022, respectively. Election of the fair value option allows Trustmark to reduce the accounting volatility that would otherwise result from the asymmetry created by accounting for the financial instruments at the lower of cost or fair value and the derivatives at fair value. The fair value option election does not apply to the GNMA optional repurchase loans which do not meet the requirements under FASB ASC Topic 825 to be accounted for under the fair value option. GNMA optional repurchase loans totaled $97.6 million and $78.8 million at December 31, 2024 and 2023, respectively, and are included in LHFS on the accompanying consolidated balance sheets.
The following table provides information about the fair value and the contractual principal outstanding of the LHFS accounted for under the fair value option at December 31, 2024 and 2023 ($ in thousands):

| Derivative Instruments and Hedging Activities Disclosure [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Derivative Financial Instruments | Note 20 – Derivative Financial Instruments Derivatives Designated as Hedging Instruments Trustmark engages in a cash flow hedging program to add stability to interest income and to manage its exposure to interest rate movements. Interest rate swaps designated as cash flow hedges involve the receipt of fixed-rate amounts from a counterparty in exchange for Trustmark making variable-rate payments over the life of the agreements without exchange of the underlying notional amount. Interest rate floor spreads designated as cash flow hedges involve the receipt of variable-rate amounts if interest rates fall below the purchased floor strike rate on the contract and payments of variable-rate amounts if interest rates fall below the sold floor strike rate on the contract. Trustmark uses such derivatives to hedge the variable cash flows associated with existing and anticipated variable-rate loan assets. At December 31, 2024, the aggregate notional value of Trustmark's interest rate swaps and floor spreads designated as cash flow hedges totaled $1.500 billion compared to $1.125 billion at December 31, 2023. Trustmark records any gains or losses on these cash flow hedges in accumulated other comprehensive income (loss). Gains and losses on derivatives representing hedge components excluded from the assessment of effectiveness are recognized over the life of the hedge on a systematic and rational basis, as documented at hedge inception in accordance with Trustmark’s accounting policy election. The earnings recognition of excluded components included in interest and fees on LHFS and LHFI totaled $474 thousand and $57 thousand of amortization expense for the years ended December 31, 2024 and 2023, respectively. As interest payments are received on Trustmark's variable-rate assets, amounts reported in accumulated other comprehensive income (loss) are reclassified into interest and fees on LHFS and LHFI in the accompanying consolidated statements of income during the same period. During the next twelve months, Trustmark estimates that $8.1 million will be reclassified as a reduction to interest and fees on LHFS and LHFI. This amount could differ due to changes in interest rates, hedge de-designations or the addition of other hedges. Derivatives not Designated as Hedging Instruments Trustmark utilizes a portfolio of exchange-traded derivative instruments, such as Treasury note futures contracts and option contracts, to achieve a fair value return that economically hedges changes in the fair value of the MSR attributable to interest rates. These transactions are considered freestanding derivatives that do not otherwise qualify for hedge accounting. The total notional amount of these derivative instruments was $311.5 million at December 31, 2024 compared to $285.0 million at December 31, 2023. Changes in the fair value of these exchange-traded derivative instruments are recorded as noninterest income in mortgage banking, net and are offset by changes in the fair value of the MSR. The impact of this strategy resulted in a net negative ineffectiveness of $9.2 million, $6.3 million and $4.1 million for the years ended December 31, 2024, 2023 and 2022, respectively. As part of Trustmark’s risk management strategy in the mortgage banking area, derivative instruments such as forward sales contracts are utilized. Trustmark’s obligations under forward sales contracts consist of commitments to deliver mortgage loans, originated and/or purchased, in the secondary market at a future date. Changes in the fair value of these derivative instruments are recorded as noninterest income in mortgage banking, net and are offset by changes in the fair value of LHFS. Trustmark’s off-balance sheet obligations under these derivative instruments totaled $110.0 million at December 31, 2024, with a positive valuation adjustment of $679 thousand, compared to $109.5 million at December 31, 2023, with a negative valuation adjustment of $994 thousand. Trustmark also utilizes derivative instruments such as interest rate lock commitments in its mortgage banking area. Interest rate lock commitments are residential mortgage loan commitments with customers, which guarantee a specified interest rate for a specified time period. Changes in the fair value of these derivative instruments are recorded as noninterest income in mortgage banking, net and are offset by the changes in the fair value of forward sales contracts. Trustmark’s off-balance sheet obligations under these derivative instruments totaled $52.1 million at December 31, 2024, with a positive valuation adjustment of $229 thousand, compared to $61.9 million at December 31, 2023, with a positive valuation adjustment of $845 thousand. Trustmark offers certain derivatives products directly to qualified commercial lending clients seeking to manage their interest rate risk. Trustmark economically hedges interest rate swap transactions executed with commercial lending clients by entering into offsetting interest rate swap transactions with institutional derivatives market participants. Derivatives transactions executed as part of this program are not designated as qualifying hedging relationships and are, therefore, carried at fair value with the change in fair value recorded as noninterest income in bank card and other fees. Because these derivatives have mirror-image contractual terms, in addition to collateral provisions which mitigate the impact of non-performance risk, the changes in fair value are expected to substantially offset. The offsetting interest rate swap transactions are either cleared through the Chicago Mercantile Exchange for clearable transactions or booked directly with institutional derivatives market participants for non-clearable transactions. The Chicago Mercantile Exchange rules legally characterize variation margin collateral payments made or received for centrally cleared interest rate swaps as settlements rather than collateral. As a result, centrally cleared interest rate swaps included in other assets and other liabilities are presented on a net basis in the accompanying consolidated balance sheets. At December 31, 2024, Trustmark had interest rate swaps with an aggregate notional amount of $1.819 billion related to this program, compared to $1.500 billion at December 31, 2023. Credit-risk-related Contingent Features Trustmark has agreements with its financial institution counterparties that contain provisions where if Trustmark defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then Trustmark could also be declared in default on its derivatives obligations. At December 31, 2024, the termination value of interest rate swaps in a liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $568 thousand compared to $1.4 million at December 31, 2023. At December 31, 2024 and 2023, Trustmark had posted collateral of $1.5 million and $2.0 million, respectively, against its obligations because of negotiated thresholds and minimum transfer amounts under these agreements. If Trustmark had breached any of these triggering provisions at December 31, 2024, it could have been required to settle its obligations under the agreements at the termination value. Credit risk participation agreements arise when Trustmark contracts with other financial institutions, as a guarantor or beneficiary, to share credit risk associated with certain interest rate swaps. These agreements provide for reimbursement of losses resulting from a third-party default on the underlying swap. At December 31, 2024, Trustmark had entered into eleven risk participation agreements as a beneficiary with an aggregate notional amount of $83.9 million compared to six risk participation agreements as a beneficiary with an aggregate notional amount of $40.1 million at December 31, 2023. At December 31, 2024, Trustmark had entered into twenty-eight risk participation agreements as a guarantor with aggregate notional amounts of $229.1 million compared to thirty-five risk participation agreements as a guarantor with aggregate notional amounts of $304.7 million at December 31, 2023. The aggregate fair values of these risk participation agreements were immaterial at December 31, 2024 and 2023.

| Segment Information | Note 21 – Segment Information Trustmark’s management reporting structure includes two segments: General Banking and Wealth Management. The General Banking Segment is responsible for all traditional banking products and services, including loans and deposits. The General Banking Segment also consists of internal operations such as Human Resources, Executive Administration, Treasury (Funds Management), Public Affairs and Corporate Finance. The Wealth Management Segment provides customized solutions for customers by integrating financial services with traditional banking products and services such as money management, full-service brokerage, financial planning, personal and institutional trust and retirement services. Trustmark's reportable segments are determined by the (CEO), who is the designated chief operating decision maker (CODM), based upon information provided about Trustmark's products and services offered. The reportable segments are also distinguished by the level of information provided to the CEO, who uses such information to review performance of various lines of business, which are then aggregated if operating performance, products and services and customers are similar. The CEO evaluates the financial performance of Trustmark's lines of business, such as evaluating revenue streams, significant expenses and budget to actual results, in assessing the performance of Trustmark's reportable segments and in the determination of allocating resources. The Insurance Segment is included in discontinued operations for all periods presented in the accompanying consolidated balance sheets and the consolidated statements of income. See Note 2 - Discontinued Operations for additional information about discontinued operations. The accounting policies of each reportable segment are the same as those of Trustmark except for its internal allocations. Noninterest expenses for back-office operations support are allocated to segments based on estimated uses of those services. Trustmark measures the net interest income of its business segments with a process that assigns cost of funds or earnings credit on a matched-term basis. This process, called “funds transfer pricing”, charges an appropriate cost of funds to assets held by a business unit, or credits the business unit for potential earnings for carrying liabilities. The net of these charges and credits flows through to the General Banking Segment, which contains the management team responsible for determining TNB’s funding and interest rate risk strategies. The following tables disclose financial information by reportable segment for the periods presented ($ in thousands):
(1) Other segment expenses for the General Banking Segment include net occupancy-premises, equipment expense, litigation settlement expense, FDIC assessment expense, other real estate expense, net, loan expense and other miscellaneous expense.

| Accounting Policies [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Business | Business Trustmark Corporation (Trustmark) is a bank holding company headquartered in Jackson, Mississippi. Through its subsidiaries, Trustmark operates as a financial services organization providing banking and financial solutions to corporate institutions and individual customers through offices in Alabama, Florida, Georgia, Mississippi, Tennessee and Texas. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Basis of Financial Statement Presentation | Basis of Financial Statement Presentation The consolidated financial statements include the accounts of Trustmark and all other entities in which Trustmark has a controlling financial interest. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain reclassifications have been made to prior period amounts to conform to the current period presentation. The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (GAAP). The preparation of financial statements in conformity with these accounting principles requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and income and expense during the reporting periods and the related disclosures. Although Management’s estimates contemplate current conditions and how they are expected to change in the future, it is reasonably possible that in 2025 actual conditions could vary from those anticipated, which could affect Trustmark’s financial condition and results of operations. Actual results could differ from those estimates. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Securities | Securities Securities are classified as either held to maturity or available for sale. Securities are classified as held to maturity and carried at amortized cost when Management has the positive intent and the ability to hold them until maturity. Securities to be held for indefinite periods of time are classified as available for sale and carried at fair value, with the unrealized holding gains and losses reported as a component of other comprehensive income (loss), net of tax. Securities available for sale are used as part of Trustmark’s interest rate risk management strategy and may be sold in response to changes in interest rates, changes in prepayment rates and other factors. Management determines the appropriate classification of securities at the time of purchase. The amortized cost of debt securities classified as securities held to maturity or securities available for sale is adjusted for amortization of premiums and accretion of discounts to maturity of the security using the interest method. Such amortization or accretion is included in interest on securities. Realized gains and losses are determined using the specific identification method and are included in noninterest income as securities gains (losses), net. Securities transferred from the available for sale category to the held to maturity category are recorded at fair value at the date of transfer. Unrealized holding gains or losses associated with the transfer of securities from available for sale to held to maturity are included in the balance of accumulated other comprehensive income (loss), net of tax, in the consolidated balance sheets. These unrealized holding gains or losses are amortized over the remaining life of the security as a yield adjustment in a manner consistent with the amortization or accretion of the original purchase premium or discount on the associated security. Allowance for Credit Losses (ACL) Financial Accounting Standards Board (FASB) Accounting Standard Codification (ASC) Topic 326 requires a current expected credit losses methodology for estimating allowances for credit losses and applies to all financial instruments carried at amortized cost, including securities held to maturity, and makes targeted improvements to the accounting for credit losses on securities available for sale. Under FASB ASC Topic 326, the ACL is an estimate measured using relevant information about past events, including historical credit loss experience on financial assets with similar risk characteristics, current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the financial assets. Trustmark adopted a zero-credit loss assumption for certain classes of securities. This zero-credit loss assumption applies to debt issuances of the U.S. Treasury and agencies and instrumentalities of the United States government. The reasons behind the adoption of the zero-credit loss assumption were as follows: • High credit rating • Long history with no credit losses • Guaranteed by a sovereign entity • Widely recognized as “risk-free rate” • Ability and authority to print its own currency • Currency is routinely held by central banks, used in international commerce, and commonly viewed as reserve currency • Currently under the U.S. Government conservatorship or receivership Trustmark continuously monitors any changes in economic conditions, credit downgrades, changes to explicit or implicit guarantees granted to certain debt issuers, and any other relevant information that would indicate potential credit deterioration and prompt Trustmark to reconsider its zero-credit loss assumption. Securities Available for Sale FASB ASC Subtopic 326-30, “Financial Instruments-Credit Losses-Available-for-Sale Debt Securities,” replaced the concept of other-than-temporarily impaired with the ACL. Unlike securities held to maturity, securities available for sale are evaluated on an individual level and pooling of securities is not allowed. Quarterly, Trustmark evaluates if any security has a fair value less than its amortized cost. Once these securities are identified, in order to determine whether a decline in fair value resulted from a credit loss or other factors, Trustmark performs further analysis as outlined below: • Review the extent to which the fair value is less than the amortized cost and observe the security’s lowest credit rating as reported by third-party credit ratings companies. • The securities that violate the credit loss triggers above would be subjected to additional analysis that may include, but is not limited to: changes in market interest rates, changes in securities credit ratings, security type, service area economic factors, financial performance of the issuer/or obligor of the underlying issue and third-party guarantee. • If Trustmark determines that a credit loss exists, the credit portion of the allowance will be measured using a discounted cash flow (DCF) analysis using the effective interest rate as of the security’s purchase date. The amount of credit loss Trustmark records will be limited to the amount by which the amortized cost exceeds the fair value. The DCF analysis utilizes contractual maturities, as well as third-party credit ratings and cumulative default rates published annually by Moody’s Investor Service (Moody’s). Accrued interest receivable is excluded from the estimate of credit losses for securities available for sale and reported in other assets on the consolidated balance sheets. Securities Held to Maturity FASB ASC Subtopic 326-20, “Financial Instruments-Credit Losses-Measured at Amortized Cost,” requires institutions to measure expected credit losses on financial assets carried at amortized cost on a collective or pool basis when similar risks exist. Trustmark uses several levels of segmentation to measure expected credit losses for its held to maturity securities: • The portfolio is segmented into agency and non-agency securities. • The non-agency securities are separated into municipal, mortgage, and corporate securities. • Each individual segment is categorized by third-party credit ratings. As discussed above, Trustmark has determined that for certain classes of securities it would be appropriate to assume the expected credit loss to be zero, which include debt issuances of the U.S. Treasury and agencies and instrumentalities of the United States government. This assumption is reviewed and attested to quarterly. Trustmark uses an internally built model to verify the accuracy of third-party provided calculations. Accrued interest receivable is excluded from the estimate of credit losses for securities held to maturity and included in other assets on the consolidated balance sheets. Trustmark monitors the credit quality of securities held to maturity on a monthly basis through credit ratings. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| LHFS | LHFS Trustmark's LHFS portfolio consists of mortgage loans purchased from wholesale customers or originated in Trustmark’s General Banking Segment. Trustmark has elected to account for its LHFS under the fair value option permitted by FASB ASC Topic 825, “Financial Instruments,” with interest income on the LHFS reported in interest and fees on LHFS and LHFI. Trustmark reports unrealized gains and losses resulting from changes in the fair value of the LHFS accounted for under the fair value option as noninterest income in mortgage banking, net. LHFS are actively managed and monitored and certain market risks of the loans may be mitigated through the use of derivatives. These derivative instruments are carried at fair value with changes in the fair value reported as noninterest income in mortgage banking, net. Changes in the fair value of the LHFS are largely offset by changes in the fair value of the derivative instruments. Election of the fair value option allows Trustmark to reduce the accounting volatility that would otherwise result from the asymmetry created by accounting for its LHFS at the lower of cost or fair value and the derivative instruments at fair value. Realized gains and losses upon ultimate sale of the loans are reported as noninterest income in mortgage banking, net. Government National Mortgage Association (GNMA) optional repurchase programs allow financial institutions to buy back individual delinquent mortgage loans that meet certain criteria from the securitized loan pool for which the institution provides servicing. At the servicer’s option and without GNMA’s prior authorization, the servicer may repurchase such a delinquent loan for an amount equal to 100 percent of the remaining principal balance of the loan. Under FASB ASC Topic 860, “Transfers and Servicing,” this buy-back option is considered a conditional option until the delinquency criteria are met, at which time the option becomes unconditional. When Trustmark is deemed to have regained effective control over these loans under the unconditional buy-back option, the loans can no longer be reported as sold and must be brought back onto the balance sheet as LHFS, regardless of whether Trustmark intends to exercise the buy-back option. These loans are reported as LHFS with the offsetting liability being reported as short-term borrowings. The fair value option election does not apply to the GNMA optional repurchase loans which do not meet the requirements under FASB ASC Topic 825 to be accounted for under the fair value option. Trustmark defers the upfront loan fees and costs related to the LHFS. In general, the LHFS are only retained on Trustmark’s balance sheet for 30 to 45 days before they are pooled and sold in the secondary market. The difference between deferring these loan fees and costs until the loans are sold and recognizing them in earnings as incurred as required by FASB ASC Subtopic 825-10 is considered immaterial. Deferred loan fees and costs are reflected in the basis of the LHFS and, as such, impact the resulting gain or loss when the loans are sold. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| LHFI | LHFI LHFI are loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off and are reported at amortized cost net of the ACL. Amortized cost is the amount of unpaid principal, adjusted for the net amount of direct costs and nonrefundable loan fees associated with lending. The net amount of nonrefundable loan origination fees and direct costs associated with the lending process, including commitment fees, is deferred and accreted to interest income over the lives of the loans using a method that approximates the interest method. Interest on LHFI is accrued and recorded as interest income based on the outstanding principal balance. Past due LHFI are loans contractually past due 30 days or more as to principal or interest payments. A LHFI is classified as nonaccrual, and the accrual of interest on such loan is discontinued, when the contractual payment of principal or interest becomes 90 days past due on commercial credits and 120 days past due on non-business purpose credits. In addition, a credit may be placed on nonaccrual at any other time Management has serious doubts about further collectability of principal or interest according to the contractual terms, even though the loan is currently performing. A LHFI may remain in accrual status if it is in the process of collection and well-secured. When a LHFI is placed in nonaccrual status, interest accrued but not received is reversed against interest income. Interest payments received on nonaccrual LHFI are applied against principal under the cost-recovery method, until qualifying for return to accrual status. Under the cost-recovery method, interest income is not recognized until the principal balance is reduced to zero. LHFI are restored to accrual status when the ultimate collectability of the total contractual principal and interest is no longer in doubt and the obligation has either been brought current or has performed in accordance with the contractual terms for a reasonable period of time. Purchased Credit Deteriorated (PCD) Loans Purchased loans which have experienced more than insignificant credit deterioration since origination are considered PCD loans. An initial ACL for PCD loans is determined at acquisition using the same ACL methodology as the LHFI. The initial ACL determined on a collective basis is allocated to individual loans. PCD loans are reported at the amortized cost, which equals the loan purchased price plus the initial ACL. The difference between the amortized cost basis of the PCD loan and the par value of the loan is the noncredit premium or discount, which is amortized into interest income over the life of the loan. Subsequent changes to the ACL are recorded through the PCL, LHFI. Upon adoption of FASB ASC Topic 326, Trustmark elected to maintain pools of loans that were previously accounted for under FASB ASC Subtopic 310-30, “Receivables-Loans and Debt Securities Acquired with Deteriorated Credit Quality,” and will continue to account for these pools as a unit of account. Loans are only removed from the existing loan pools if they are written off, paid off or sold. Upon adoption of FASB ASC Topic 326, the ACL was determined for each pool and added to the pool’s carrying value to establish a new amortized cost basis. The difference between the unpaid principal balance of the pool and the new amortized cost basis is the noncredit premium or discount which will be amortized into interest income over the remaining life of the pool. Changes to the ACL after adoption of FASB ASC Topic 326 are recorded through the PCL, LHFI. ACL LHFI Trustmark’s ACL methodology for LHFI is based upon guidance within FASB ASC Subtopic 326-20 as well as applicable regulatory guidance. The ACL on LHFI is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans. Credit quality within the LHFI portfolio is continuously monitored by Management and is reflected within the ACL on LHFI. The ACL on LHFI is an estimate of expected losses inherent within Trustmark’s existing LHFI portfolio. The ACL on LHFI is adjusted through the PCL, LHFI and reduced by the charge off of loan amounts, net of recoveries. The loan loss estimation process involves procedures to appropriately consider the unique characteristics of Trustmark’s LHFI portfolio segments. These segments are further disaggregated into loan classes, the level at which credit risk is estimated. When computing allowance levels, credit loss assumptions are estimated using a model that categorizes loan pools based on loss history, delinquency status and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. Evaluations of the portfolio and individual credits are inherently subjective, as they require estimates, assumptions and judgments as to the facts and circumstances of particular situations. Determining the appropriateness of the allowance is complex and requires judgment by Management about the effect of matters that are inherently uncertain. In future periods, evaluations of the overall LHFI portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the allowance and credit loss expense. Trustmark estimates the ACL on LHFI using relevant available information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Trustmark uses a third-party software application to calculate the quantitative portion of the ACL on LHFI using a methodology and assumptions specific to each loan pool. The qualitative portion of the allowance is based on general economic conditions and other internal and external factors affecting Trustmark as a whole as well as specific LHFI. Factors considered include the following: lending policies and procedures, economic conditions and concentrations of credit, nature and volume of the portfolio, performance trends, and external factors. The quantitative and qualitative portions of the allowance are added together to determine the total ACL on LHFI, which reflects Management’s expectations of future conditions based on reasonable and supportable forecasts. The methodology for estimating the amount of expected credit losses reported in the ACL on LHFI has two basic components: a collective, or pooled, component for estimated expected credit losses for pools of loans that share similar risk characteristics, and an asset-specific component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans. In estimating the ACL for the collective component, loans are segregated into loan pools based on loan product types and similar risk characteristics. Trustmark determined that reasonable and supportable forecasts could be made for a twelve-month period for all of its loan pools. To the extent the lives of the loans in the LHFI portfolio extend beyond this forecast period, Trustmark uses a reversion period of four quarters and reverts to the historical mean on a straight-line basis over the remaining life of the loans. The ACL for individual loans that do not share risk characteristics with other loans is measured as the difference between the discounted value of expected future cash flows, based on the effective interest rate at origination, and the amortized cost basis of the loan, or the net realizable value. The ACL is the difference between the loan’s net realizable value and its amortized cost basis (net of previous charge-offs and deferred loan fees and costs), except for collateral-dependent loans. A loan is collateral dependent when the borrower is experiencing financial difficulty and repayment of the loan is expected to be provided substantially through the sale of the collateral. The expected credit loss for collateral-dependent loans is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral, adjusted for the estimated cost to sell. Fair value estimates for collateral-dependent loans are derived from appraised values based on the current market value or the ‘as is’ value of the collateral, normally from recently received and reviewed appraisals. Current appraisals are ordered on an annual basis based on the inspection date or more often if market conditions necessitate. Appraisals are obtained from state-certified appraisers and are based on certain assumptions, which may include construction or development status and the highest and best use of the property. These appraisals are reviewed by Trustmark’s Appraisal Review Department to ensure they are acceptable, and values are adjusted down for costs associated with asset disposal. If the calculated expected credit loss is determined to be permanent or not recoverable, the amount of the expected credit loss is charged off. Accrued interest receivable is not included in the amortized cost basis of Trustmark’s LHFI and, therefore, excluded from the estimate of credit losses for LHFI. LHFI are charged off against the ACL on LHFI, with any subsequent recoveries credited back to the ACL on LHFI account. Recoveries may not exceed the aggregate of amounts previously charged off. Trustmark’s Loan Policy Manual dictates the guidelines to be followed in determining when a loan is charged off. Commercial purpose LHFI are charged off when a determination is made that the loan is uncollectible and continuance as a bankable asset is not warranted. Consumer LHFI secured by 1-4 family residential real estate are generally charged off or written down to the fair value of the collateral less cost to sell at no later than 180 days of delinquency. Non-real estate consumer purpose LHFI, including both secured and unsecured loans, are generally charged off by 120 days of delinquency. Consumer revolving lines of credit and credit card debt are generally charged off on or prior to 180 days of delinquency. ACL on Off-Balance Sheet Credit Exposures Under FASB ASC Subtopic 326-20, Trustmark is required to estimate expected credit losses for off-balance sheet credit exposures which are not unconditionally cancellable. Trustmark maintains a separate ACL on off-balance sheet credit exposures, including unfunded loan commitments and letters of credit. Expected credit losses for off-balance sheet credit exposures are estimated by calculating a commitment usage factor over the contractual period for exposures that are not unconditionally cancellable by Trustmark. Trustmark calculates a loan pool level unfunded amount for the period. Trustmark views the loan pools as either closed-ended or open-ended. Closed-ended loan pools are those that typically fund up to 100% such as other construction and nonowner-occupied. Open-ended loan pools are those that behave similar to a revolver such as the commercial and industrial and home equity line of credit loan pools. In addition to the unfunded balances, Trustmark uses a funding rate for loan pools that are considered open-ended. Trustmark calculates the funding rate of the open-ended loan pools each period. In order to mitigate volatility and incorporate historical experience in the funding rate, Trustmark uses a twelve-quarter moving average. For the closed-ended loan pools, Trustmark takes a conservative approach and uses a 100% funding rate. The expected funding rate is applied to each pool’s unfunded commitment balances to ensure that reserves will be applied to each pool based on balances expected to be funded based upon historical levels. In addition to the funding rate being applied to the unfunded commitment balance, a reserve rate is applied, which includes both quantitative and a majority of the qualitative aspects of the current period's expected credit loss rate. During 2024, Management implemented a performance trends qualitative factor for unfunded commitments and an External Factor - Credit Quality Review qualitative factor for unfunded commitments. For both qualitative factors, the same assumptions are applied in the unfunded commitment calculation that are used in the funded balance calculation with the only difference being the unfunded commitment calculation includes the funding rates for the unfunded commitments. The reserves for these two qualitative factors are added to the other calculated reserve to get a total reserve for off-balance sheet credit exposures. Adjustments to the ACL on off-balance sheet credit exposures are recorded to the PCL, off-balance sheet credit exposures. No credit loss estimate is reported for off-balance sheet credit exposures that are unconditionally cancellable by Trustmark or for undrawn amounts under such arrangements that may be drawn prior to the cancellation of the arrangement. |

| Premises and Equipment, Net | Premises and Equipment, Net Premises and equipment are reported at cost, less accumulated depreciation and amortization. Depreciation is charged to expense over the estimated useful lives of the assets, which are up to thirty-nine years for buildings and to ten years for furniture and equipment. Leasehold improvements are amortized over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. In cases where Trustmark has the right to renew the lease for additional periods, the lease term for the purpose of calculating amortization of the capitalized cost of the leasehold improvements is extended when Trustmark is “reasonably assured” that it will renew the lease. Depreciation and amortization expenses are computed using the straight-line method. Trustmark continually evaluates whether events and circumstances have occurred that indicate that such long-lived assets have become impaired. Measurement of any impairment of such long-lived assets is based on the fair values of those assets. Branch closures and purchased land held for future branch expansion for more than five years are evaluated to determine if the related land, buildings and building improvements should be transferred to assets held for sale in accordance with FASB ASC Topic 360, “Property, Plant and Equipment.” The property is transferred to assets held for sale at the lower of its carrying value or fair value less cost to sell. An impairment loss is recorded at the time of transfer if the carrying value of the assets exceeds the fair value. Impairment losses are recorded as noninterest expense in other expense. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| MSR | MSR Trustmark recognizes as assets the rights to service mortgage loans based on the estimated fair value of the MSR when loans are sold and the associated servicing rights are retained. Trustmark has elected to account for the MSR at fair value. The fair value of the MSR is determined using a valuation model administered by a third party that calculates the present value of estimated future net servicing income. Estimates of fair value involve several assumptions, including the key valuation assumptions about market expectations of future prepayment rates, interest rates and discount rates which are provided by a third-party firm. Prepayment rates are projected using an industry standard prepayment model. The model considers other key factors, such as a wide range of standard industry assumptions tied to specific portfolio characteristics such as remittance cycles, escrow payment requirements, geographic factors, foreclosure loss exposure, VA no-bid exposure, delinquency rates and cost of servicing, including base cost and cost to service delinquent mortgages. Prevailing market conditions at the time of analysis are factored into the accumulation of assumptions and determination of servicing value. Trustmark economically hedges changes in the fair value of the MSR attributable to interest rates. See the section titled “Derivative Financial Instruments – Derivatives Not Designated as Hedging Instruments” of this note for information regarding these derivative instruments. Trustmark receives annual servicing fee income for loans serviced, which is recorded as noninterest income in mortgage banking, net. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. Late fees and ancillary fees related to loan servicing are not considered material. |

| Goodwill and Identifiable Intangible Assets | Goodwill and Identifiable Intangible Assets Trustmark accounts for goodwill and other intangible assets in accordance with FASB ASC Topic 350, “Intangibles – Goodwill and Other.” Goodwill, which represents the excess of cost over the fair value of the net assets of an acquired business, is not amortized but tested for impairment on an annual basis, which is October 1 for Trustmark, or more often if events or circumstances indicate that there may be impairment. Identifiable intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or legal rights or because the assets are capable of being sold or exchanged either on their own or in combination with a related contract, asset or liability. Trustmark’s identifiable intangible assets primarily relate to core deposits and borrower relationships. These intangibles, which have definite useful lives, are amortized on an accelerated basis over their estimated useful lives. In addition, these intangibles are evaluated for impairment whenever events and changes in circumstances indicate that the carrying amount should be reevaluated. Trustmark also purchased banking charters in order to facilitate its entry into the states of Florida and Texas. These identifiable intangible assets were amortized on a straight-line method over 20 years. |

| Other Real Estate | Other Real Estate Other real estate includes assets that have been acquired in satisfaction of debt through foreclosure and is recorded at the fair value less cost to sell (estimated fair value) at the time of foreclosure. Fair value is based on independent appraisals and other relevant factors. When foreclosed real estate is received in full satisfaction of a loan, the amount, if any, by which the recorded amount of the loan exceeds the estimated fair value of the property is a loss charged against the ACL at the time of foreclosure. If the recorded amount of the loan is less than the estimated fair value of the property, a credit is recorded to write-downs of other real estate at the time of foreclosure. Other real estate is revalued on an annual basis or more often if market conditions necessitate. An other real estate specific reserve may be recorded through other real estate expense for declines in fair value subsequent to foreclosure based on recent appraisals or changes in market conditions. Subsequent to foreclosure, losses on the periodic revaluation of the property are charged against an existing other real estate specific reserve or as noninterest expense in other real estate expense if a reserve does not exist. Costs of operating and maintaining the properties as well as gains or losses on their disposition are also included in other real estate expense as incurred. Improvements made to properties are capitalized if the expenditures are expected to be recovered upon the sale of the properties. |

| Lessor Arrangements | Lessor Arrangements Trustmark leases certain types of machinery and equipment to its commercial customers through sales-type and direct financing leases as part of its equipment financing portfolio. Sales-type and direct financing leases are similar to other forms of installment lending in that lessors generally do not retain benefits and risks incidental to ownership of the property subject to the leases. Such arrangements are essentially financing transactions that permit lessees to acquire and use property. Trustmark does not have any significant operating leases in which it is the lessor. As lessor, the sum of all minimum lease payments over the lease term and the estimated residual value, less unearned interest income, is recorded as the net investment in the lease on the commencement date and is included in LHFI on the consolidated balance sheets. Interest income is accrued as earned over the term of the lease based on the net investment in the leases and is recognized in interest and fees on LHFS and LHFI on the consolidated statements of income. Certain fees or costs associated with lease originations are deferred and accreted or amortized to interest income over the life of the lease using the effective interest method. Trustmark’s portfolio of sales-type and direct financing leases generally have remaining lease terms of three to ten years, some of which include renewal options and/or options for the lessee to purchase the leased property near or at the end of the lease term at either the residual value or a specified price. Trustmark expects to sell or release the equipment at the end of the lease term. Due to the structure of these leases, there is no selling profit or loss on these transactions. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Lessee Arrangements | Lessee Arrangements Trustmark has certain contracts that it has identified as leases according to FASB ASC Topic 842, "Leases". Trustmark classifies these leases as either operating or finance leases and recognizes a right-of-use asset and a lease liability at the lease commencement date. The lease liability represents the present value of the lease payments that remain unpaid as of the commencement date and the right-of-use asset is the initial lease liability recognized for the lease plus any lease payments made to the lessor at or before the commencement date as well as any initial direct costs less any lease incentives received. Trustmark accounts for the lease and nonlease components separately as such amounts are readily determinable. Trustmark’s finance leases consist of building and equipment leases. Trustmark recognizes interest expense based on the discount rate of the lease as interest expense in other interest expense and recognizes depreciation expense on a straight-line basis over the lease term as noninterest expense in net occupancy – premises for building leases and in equipment expense for equipment leases. Trustmark amortizes the right-of-use asset over the life of the lease term on a straight-line basis. Trustmark’s lease liabilities are measured as the present value of the remaining lease payments throughout the lease term. Trustmark records its finance lease right-of-use assets in premises and equipment, net and its finance lease liabilities in other borrowings. Trustmark’s operating leases primarily consist of building and land leases. Trustmark recognizes lease rent expense on a straight-line basis over the term of the lease contract and records it as noninterest expense in net occupancy – premises for building and land leases and in equipment expense for equipment leases. Trustmark’s amortization of the right-of-use asset is the difference between the straight-line lease expense and the interest expense recognized on the lease liability during the period. Trustmark’s lease liabilities are measured as the present value of the remaining lease payments throughout the lease term. Trustmark’s leases typically have one or more renewal options included in the lease contract. Due to the nature of Trustmark’s leases, for leases with renewal options available, Trustmark considers the first renewal option as reasonably certain to renew and is therefore included in the measurement of the right-of-use assets and lease liabilities. In order to calculate its right-of-use assets and lease liabilities, FASB ASC Topic 842 requires Trustmark to use the rate of interest implicit in the lease when readily determinable. If the rate implicit in the lease is not readily determinable, Trustmark is required to use its incremental borrowing rate, which is the rate of interest Trustmark would have to pay to borrow on a collateralized basis over a similar term in a similar economic environment. Trustmark was able to determine the implicit interest rate for its equipment leases and used that rate as its discount rate. Since the implicit interest rate for most of its building and land leases were not readily determinable, Trustmark used its incremental borrowing rate. Trustmark made an accounting policy election to not recognize short-term leases (12 months or less) on the balance sheet. Trustmark’s short-term leases primarily include automated teller machines. For short-term leases, Trustmark recognizes lease expense on a straight-line basis over the lease term. |

| Federal Home Loan Bank (FHLB) and Federal Reserve Bank of Atlanta Stock | Federal Home Loan Bank (FHLB) and Federal Reserve Bank of Atlanta Stock Trustmark accounts for its investments in FHLB and Federal Reserve Bank of Atlanta stock in accordance with FASB ASC Subtopic 942-325, “Financial Services-Depository and Lending-Investments-Other.” FHLB and Federal Reserve Bank stock are equity securities that do not have a readily determinable fair value because its ownership is restricted and it lacks a market. FHLB and Federal Reserve Bank stock are carried at cost and evaluated for impairment. Trustmark’s investment in member bank stock is included in other assets in the accompanying consolidated balance sheets. At December 31, 2024 and 2023, Trustmark’s investment in member bank stock totaled $44.9 million and $54.4 million, respectively. The carrying value of Trustmark’s member bank stock gave rise to no other-than-temporary impairment for the years ended December 31, 2024, 2023 and 2022. |

| Revenue from Contract with Customers | Revenue from Contracts with Customers Trustmark accounts for revenue from contracts with customers in accordance with FASB ASC Topic 606, “Revenue from Contracts with Customers,” which provides that revenue be recognized in a manner that depicts the transfer of goods or services to a customer in an amount that reflects the consideration Trustmark expects to be entitled to in exchange for those goods or services. Revenue from contracts with customers is recognized either over time in a manner that depicts Trustmark’s performance, or at a point in time when control of the goods or services are transferred to the customer. Trustmark’s noninterest income, excluding all of mortgage banking, net and securities gains (losses), net and portions of bank card and other fees and other, net, are considered within the scope of FASB ASC Topic 606. Gains or losses on the sale of other real estate, which are included in Trustmark’s noninterest expense as other expense, are also within the scope of FASB ASC Topic 606. General Banking Segment Service Charges on Deposit Accounts In general, deposit accounts represent contracts with customers with no fixed duration and can be terminated or modified by either party at any time without compensation to the other party. According to FASB ASC Topic 606, a contract that can be terminated by either party without compensation does not exist for periods beyond the then-current period. Therefore, deposit contracts are considered to renew day-to-day if not minute-to-minute. Deposit contracts have a single continuous or stand-ready service obligation whereby Trustmark makes customer funds available for use by the customer as and when the customer chooses as well as other services such as statement rendering and online banking. The specific services provided vary based on the type of deposit account. These services are not individually distinct, but are distinct as a group, and therefore, constitute a single performance obligation which is satisfied over time and qualifies as a series of distinct service periods. Trustmark receives a fixed service charge amount as consideration monthly for services rendered. The service charge amount varies based on the type of deposit account. Some of the service charge revenue is subject to refund provisions, which is variable consideration under the guidelines of FASB ASC Topic 606. Trustmark has elected the ‘as-invoiced’ practical expedient permitted under FASB ASC Topic 606 for recognition of service charge revenue. Therefore, revenue is recognized at the time and in the amount the customer is charged. The service charge revenue is presented net of refunded amounts on Trustmark’s consolidated statements of income. Services related to non-sufficient funds, overdrafts, excess account activity, stop payments, dormant accounts, etc. are considered optional purchases for a deposit contract because there is no performance obligation for Trustmark until the service is requested by the customer or the occurrence of a triggering event. Fees for these services are fixed amounts and are charged to the customer when the service is performed. Revenue is recognized at the time the customer is charged. Bank Card and Other Fees Revenue from contracts with customers in bank card and other fees includes income related to interchange fees and various other contracts which primarily consists of contracts with a single performance obligation that is satisfied at a point in time. Trustmark receives a fixed consideration amount once the performance obligation is completed for these contracts. Trustmark reports revenue from these contracts net of amounts refunded or due to a third party. As both a debit and credit card issuer, Trustmark receives an interchange fee for every card transaction completed by its customers with a merchant. Trustmark receives two types of interchange fees: point-of-sale transactions in which the customer must enter the PIN associated with the card to complete the transaction (a debit card transaction), and signature transactions in which the signature of the customer is required to complete the transaction (a credit card transaction). Trustmark, as the card issuing or settlement bank, has a contract (implied based on customary business practices) with the payment network in which Trustmark has a single continuous service obligation to make funds available for settlement of the card transaction. Trustmark’s service obligation is satisfied over time and qualifies as a series of distinct service periods. Trustmark receives interchange fees as consideration for services rendered in the amount established by the respective payment network. The interchange fees are established by the payment network based on the type of transaction and is posted on their website. Trustmark receives and records interchange fee revenue from the payment networks daily net of all fees and amounts due to the payment network. Other Income Revenue from contracts with customers in other income includes income related to cash management services and other contracts with a single performance obligation that is satisfied at a point in time. Trustmark receives a fixed consideration amount once the performance obligation is completed for these contracts. Trustmark reports revenue from these contracts net of amounts refunded or due to a third party. Trustmark provides cash management services through the delivery of various products and services offered to its business and municipal customers including various departments of state, city and local governments, universities and other non-profit entities. Similar to the deposit account contracts, the cash management contracts primarily represent contracts with customers with no fixed duration and can be terminated or modified by either party at any time without compensation to the other party. Therefore, cash management contracts are generally considered to renew day-to-day if not minute-to-minute. Cash management contracts have a single continuous or stand-ready service obligation whereby Trustmark makes a specific service or group of services available for use by the customer as and when the customer chooses. The specific services provided vary based on the type of account or product. These services are not individually distinct, but are distinct as a group, and therefore, constitute a single performance obligation which is satisfied over time and qualifies as a series of distinct service periods. Trustmark receives a set service charge or maintenance fee amount as consideration monthly for services rendered. However, some of the fees are based on the number of transactions that occur (i.e., flat fee for a set number of transactions per month then an additional charge for each transaction after that) or the average daily account balance maintained by the customer during the month and a small amount of the cash management fee revenue is subject to refund provisions. These fees represent variable consideration under the guidelines of FASB ASC Topic 606. Trustmark has elected the ‘as-invoiced’ practical expedient permitted under FASB ASC Topic 606 for recognition of cash management fee revenue. The cash management revenue is presented net of any refunded amounts on Trustmark’s consolidated statements of income. Trustmark’s merchant services provider contracts directly with Trustmark business customers and provides Trustmark’s merchant customers card processing equipment and transaction processing services. Trustmark’s contract with the merchant services provider has a single-continuous service obligation to provide customer referrals for potential new accounts which is satisfied over time and qualifies as a series of distinct service periods. Trustmark receives a flat fee for each new account established and a percentage of the residual income related to transactions processed for Trustmark’s merchant customers each month as provided in the contract. Under the guidelines of FASB ASC Topic 606, the fee received for each new account and the profit sharing represent variable consideration. Revenue from merchant card services contracts is recognized monthly using a time-elapsed measure of progress. Trustmark has elected the ‘as-invoiced’ practical expedient permitted under FASB ASC Topic 606 for recognition of the merchant card services revenue. Other Real Estate Trustmark records a gain or loss from the sale of other real estate when control of the property transfers to the buyer. Trustmark records the gain or loss from the sale of other real estate in noninterest expense as other expense. Other real estate sales for the year ended December 31, 2024 resulted in a net loss of $1.1 million compared to a net loss of $145 thousand for the year ended December 31, 2023 and a net loss of $1.0 million for the year ended December 31, 2022. In general, purchases of Trustmark’s other real estate property are not financed by Trustmark. Financing the purchase of other real estate is evaluated based upon the same lending policies and procedures as all other types of loans. Under FASB ASC Subtopic 610-20, “Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets,” when Trustmark finances the sale of its other real estate to a buyer, Trustmark is required to assess whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these two criteria are met, Trustmark derecognizes the other real estate asset and records a gain or loss on the sale once control of the property is transferred to the buyer. Wealth Management Segment Trust Management There are four categories of revenue included in trust management: personal trust and investments, retirement plan services, institutional custody and other. Each of these categories includes multiple types of contracts, service obligations and fee income. However, the majority of these contracts include a single service obligation that is satisfied over time, the customer is charged in arrears for services rendered and revenue is recognized when payment is received. In general, the time period between when the service obligation is completed and when payment from the customer is received is less than 30 days. Revenue from trust management contracts is primarily related to monthly service periods and based on the prior month-end’s market value. Some trust management revenue is mandated by a court order, while other revenue consists of flat fees. Trust management revenue based on an account’s market value represents variable consideration under the guidelines of FASB ASC Topic 606. Trustmark has elected the ‘as-invoiced’ practical expedient allowed under FASB ASC Topic 606 to account for the trust management revenue. Assets under administration held by Trustmark in a fiduciary or agency capacity for customers are not included in Trustmark’s consolidated balance sheets. Investment Services Investment services includes both brokerage and annuity income. Trustmark has a contract with a third-party investment services company which contains a single continuous service obligation, to provide broker-dealer and advisory services to customers on behalf of the third-party, which is satisfied over time and qualifies as a series of distinct service periods. Trustmark serves as the agent between the third-party investment services company, the principle, and the customer. In accordance with the contract, Trustmark receives a monthly payment from the investment services company for commissions and advisory fees (asset management fees) earned on transactions completed in the prior month net of all charges and fees due to the investment services company. Trustmark recognizes revenue from the investment services company, net of the revenue sharing expense due to the investment services company, when the payments are received. Commissions vary from month-to-month based on the specific products and transactions completed. The advisory fees vary based on the average daily balance of the managed assets for the period. The commissions and advisory fees represent variable consideration under FASB ASC Topic 606. Trustmark has elected the ‘as-invoiced’ practical expedient allowed under FASB ASC Topic 606 to recognize revenue from the investment services company. |

| Derivative Financial Instruments | Derivative Financial Instruments Trustmark maintains an overall interest rate risk management strategy that incorporates the use of derivative instruments to minimize significant unplanned fluctuations in earnings and cash flows caused by interest rate volatility. Trustmark’s interest rate risk management strategy involves modifying the repricing characteristics of certain assets and liabilities so that changes in interest rates do not adversely affect the net interest margin and cash flows. Under the guidelines of FASB ASC Topic 815, “Derivatives and Hedging,” all derivative instruments are required to be recognized as either assets or liabilities and carried at fair value on the balance sheet. The fair value of derivative positions outstanding is included in other assets and/or other liabilities in the accompanying consolidated balance sheets and in the net change in these financial statement line items in the accompanying consolidated statements of cash flows as well as included in noninterest income in the accompanying consolidated statements of income and other comprehensive income (loss), net of tax in the accompanying consolidated statements of comprehensive income. Trustmark’s interest rate derivative instruments are subject to master netting agreements, and therefore, eligible for offsetting in the consolidated balance sheets. Trustmark has elected to not offset any derivative instruments in its consolidated balance sheets. Derivatives Designated as Hedging Instruments FASB ASC Topic 815, Derivatives and Hedging (ASC 815), provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments. Derivatives designated and qualifying as a hedge of the 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. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. When entering into a hedge transaction, Trustmark formally documents the relationship between the hedging instrument and the hedged item, as well as the risk management objective and strategy for undertaking the hedge transaction, which includes designating the derivative instrument as a fair value or cash flow hedge to a specific asset or liability on the balance sheet or to specific forecasted transactions and the risk being hedged, along with a formal assessment at the inception of the hedge as to the effectiveness of the derivative instrument in offsetting changes in fair values or cash flows of the hedged item. Trustmark continues to assess hedge effectiveness on an ongoing basis using either a qualitative or a quantitative assessment (regression analysis). As required by ASC 815, Trustmark records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether Trustmark has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. For cash flow hedges, changes in the fair value of the derivative instrument are recorded in accumulated other comprehensive income (loss) and subsequently reclassified to net income in the same period that the hedged transaction impacts net income. Upon discontinuation of hedge accounting for cash flow hedges, any amounts in accumulated other comprehensive income (loss) related to that relationship affects earnings at the same time and in the same manner in which the hedged transaction affects earnings. If it becomes probable that the forecasted transaction will not occur, any related amounts in accumulated other comprehensive income (loss) are reclassified to earnings immediately. Derivatives Not Designated as Hedging Instruments As part of Trustmark’s risk management strategy in the mortgage banking area, derivative instruments such as forward sales contracts are utilized. Trustmark’s obligations under forward contracts consist of commitments to deliver mortgage loans, originated and/or purchased, in the secondary market at a future date. Changes in the fair value of these derivative instruments are recorded as noninterest income in mortgage banking, net and are offset by changes in the fair value of LHFS. See Note 1 – Significant Accounting Policies, “LHFS” for information regarding the fair value option election. Trustmark also utilizes derivative instruments such as interest rate lock commitments in its mortgage banking area. Rate lock commitments are residential mortgage loan commitments with customers, which guarantee a specified interest rate for a specified time period. Changes in the fair value of these derivative instruments are recorded as noninterest income in mortgage banking, net and are offset by the changes in the fair value of forward sales contracts. Trustmark utilizes a portfolio of exchange-traded derivative instruments, such as Treasury note futures contracts and option contracts, to achieve a fair value return that economically hedges changes in the fair value of the MSR attributable to interest rates. These transactions are considered freestanding derivatives that do not otherwise qualify for hedge accounting. These exchange-traded derivative instruments are accounted for at fair value with changes in the fair value recorded as noninterest income in mortgage banking, net and are offset by changes in the fair value of the MSR. The MSR fair value represents the present value of future cash flows, which among other things includes decay and the effect of changes in interest rates. Ineffectiveness of hedging the MSR fair value is measured by comparing the change in the fair value of the hedge instruments to the change in the fair value of the MSR asset attributable to changes in interest rates and other market driven changes in valuation inputs and assumptions. Trustmark offers certain derivatives products directly to qualified commercial lending clients seeking to manage their interest rate risk. Trustmark economically hedges interest rate swap transactions executed with commercial lending clients by entering into offsetting interest rate swap transactions with institutional derivatives market participants. Derivative transactions executed as part of this program are not designated as qualifying hedging relationships and are, therefore, carried at fair value with the change in fair value recorded as noninterest income in bank card and other fees. Because these derivatives have mirror-image contractual terms, in addition to collateral provisions which mitigate the impact of non-performance risk, the changes in fair value are expected to substantially offset. The offsetting interest rate swap transactions are either cleared through the Chicago Mercantile Exchange for clearable transactions or booked directly with institutional derivatives market participants for non-clearable transactions. The Chicago Mercantile Exchange rules legally characterize variation margin collateral payments made or received for centrally cleared interest rate swaps as settlements rather than collateral. As a result, centrally cleared interest rate swaps included in other assets and other liabilities are presented on a net basis in the accompanying consolidated balance sheets. |

| Income Taxes | Income Taxes Trustmark accounts for uncertain tax positions in accordance with FASB ASC Topic 740, “Income Taxes,” which clarifies the accounting and disclosure for uncertainty in tax positions. Under the guidance of FASB ASC Topic 740, Trustmark accounts for deferred income taxes using the liability method. Deferred tax assets and liabilities are based on temporary differences between the financial statement carrying amounts and the tax basis of Trustmark’s assets and liabilities. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be realized or settled and are presented net in the accompanying consolidated balance sheets in other assets. |

| Stock-Based Compensation | Stock-Based Compensation Trustmark accounts for the stock and incentive compensation under the provisions of FASB ASC Topic 718, “Compensation – Stock Compensation.” Under this accounting guidance, fair value is established as the measurement objective in accounting for stock awards and requires the application of a fair value based measurement method in accounting for compensation cost, which is recognized over the requisite service period. Trustmark has elected to account for forfeitures of stock awards as they occur. |

| Per Share Data | Per Share Data Trustmark accounts for per share data in accordance with FASB ASC Topic 260, “Earnings Per Share,” which provides that unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of EPS pursuant to the two-class method. Trustmark has determined that its outstanding unvested stock awards are not participating securities. Based on this determination, no change has been made to Trustmark’s current computation for basic and diluted EPS. Basic EPS is computed by dividing net income by the weighted-average shares of common stock outstanding. Diluted EPS is computed by dividing net income by the weighted-average shares of common stock outstanding, adjusted for the effect of potentially dilutive stock awards outstanding during the period. The following table reflects weighted-average shares used to calculate basic and diluted EPS for the periods presented (in thousands):
Weighted-average antidilutive stock awards were excluded in determining diluted EPS. The following table reflects weighted-average antidilutive stock awards for the periods presented (in thousands):

| Fair Value Measurements | Fair Value Measurements FASB ASC Topic 820, “Fair Value Measurements and Disclosures,” defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and requires certain disclosures about 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. Depending on the nature of the asset or liability, Trustmark uses various valuation techniques and assumptions when estimating fair value. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. FASB ASC Topic 820 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 – Valuation is based upon quoted prices (unadjusted) in active markets for identical assets or liabilities that Trustmark has the ability to access at the measurement date. Level 2 Inputs – Valuation is based upon quoted prices in active markets for similar assets or liabilities, 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, yield curves, volatilities and default rates and inputs that are derived principally from or corroborated by observable market data. Level 3 Inputs – Unobservable inputs reflecting the reporting entity’s own determination about the assumptions that market participants would use in pricing the asset or liability based on the best information available. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the fair value measurement in its entirety is classified is based on the lowest level input that is significant to the fair value measurement in its entirety. Trustmark’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer. |

| Accounting Policies Recently Adopted | Accounting Policies Recently Adopted Except for the changes detailed below, Trustmark has consistently applied its accounting policies to all periods presented in the accompanying consolidated financial statements. ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” Issued in November 2023, ASU 2023-07 is intended to improve disclosures about a public entity’s reportable segments and address requests from investors and other allocators of capital for additional, more detailed information about a reportable segment’s expenses. The amendments of ASU 2023-07 require a public entity to disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and included within each reported measure of segment profit or loss, and an amount for other segment items by reportable segment and a description of its composition. The other segment items category is the difference between segment revenue less the significant expenses disclosed and each reported measure of segment profit or loss. ASU 2023-07 also requires a public entity to provide all annual disclosures about a reportable segment’s profit or loss and assets currently required under FASB ASC Topic 280 in interim periods. The amendments of ASU 2023-07 clarify that if the CODM uses more than one measure of a segment's profit or loss in assessing segment performance and deciding how to allocate resources, a public entity may report one or more of those additional measures of segment profit. However, at least one of the reported segment profit or loss measures (or the single reported measure if only one is disclosed) should be the measure that is most consistent with the measurement principles used in measuring the corresponding amounts in the public entity's consolidated financial statements. ASU 2023-07 requires a public entity to disclose the title and position of the CODM, together with an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. In addition, ASU 2023-07 requires that a public entity with a single reportable segment provide all the disclosures required by the amendments of ASU 2023-07 and all existing segment disclosures in FASB ASC Topic 280. The amendments of ASU 2023-07 are effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments in ASU 2023-07 should be applied retrospectively to all periods presented on the financial statements. Upon implementation, the segment expense categories and amounts disclosed in the prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. Trustmark adopted the amendments of ASU 2023-07 related to annual disclosure requirements effective January 1, 2024, and the newly required annual disclosures are included in Note 21 – Segment Information of this report. Trustmark adopted the amendments of ASU 2023-07 related to interim disclosure requirements effective January 1, 2025, and will present any newly required interim disclosures beginning with its Quarterly Report on Form 10-Q for the period ending March 31, 2025. Adoption of ASU 2023-07 did not have a material impact to Trustmark’s consolidated financial statements or results of operations. ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” Issued in December 2023, ASU 2023-09 is intended to improve the disclosures for income taxes to address requests from investors, lenders, creditors and other allocators of capital (collectively, "investors") that use the financial statements to make capital allocation decisions. During the FASB's 2021 agenda consultation process and other stakeholder outreach, investors highlighted that the current system of income tax disclosures does not provide enough information to understand the tax provision for an entity that operates in multiple jurisdictions. Investors currently rely on the rate reconciliation table and other disclosures, including total income taxes paid in the statement of cash flows, to evaluate income tax risks and opportunities. The amendments in ASU 2023-09 will require consistent categories and greater disaggregation of information in the rate reconciliation disclosure as well as disclosure of income taxes paid disaggregated by jurisdiction. The amendments of ASU 2023-09 are effective for annual periods beginning after December 15, 2024, and early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. Trustmark adopted the amendments of ASU 2023-09 effective January 1, 2025, and will include the required disclosures in its Annual Report on Form 10-K for the year ending December 31, 2025. Trustmark is currently evaluating the changes to disclosures required by ASU 2023-09; however, adoption of ASU 2023-09 is not expected to have a material impact to Trustmark’s consolidated financial statements or results of operations. Pending Accounting Pronouncements ASU 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” Issued in November 2024, ASU 2024-03 with the objective of providing investors with more decision-useful information regarding a public business entity's expenses by enhancing disclosures on income statement expenses. Investor feedback indicated a strong preference for the disclosure of disaggregated financial reporting information as a top priority for the FASB. Detailed knowledge of an entity's expenses is crucial for understanding its prospects for future cash flows and for making performance comparisons over time and with other entities. Investors emphasized that information regarding cost of sales, selling, general, and administrative expenses, employee compensation costs, depreciation and amortization, and research and development expenditure would enhance their comprehension of an entity's cost structure and ability to forecast future cash flows. The ASU applies exclusively to public business entities and mandates additional disclosures about specific expense categories on both annual and interim bases in the notes to financial statements that are not currently required. The amendments do not alter or eliminate existing expense disclosure requirements nor change requirements for presenting expenses on the face of the income statement. However, they do specify that certain existing disclosures must now appear in the same tabular format as the new disaggregation requirements. The FASB issued ASU 2025-01 in January 2025, clarifying that the amendments in ASU 2024-03 are effective for public business entities for annual reporting periods beginning after December 15, 2026, and for interim reporting periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. Trustmark intends to adopt the amendments of ASU 2024-03 effective January 1, 2027, and will include the required annual disclosures in its Annual Report on Form 10-K for the year ending December 31, 2027, and required interim disclosures in its Quarterly Report on Form 10-Q for the period ending March 31, 2028. Trustmark is currently evaluating the changes to disclosures required by ASU 2024-03; however, adoption of ASU 2024-03 is not expected to have a material impact to Trustmark’s consolidated financial statements or results of operations. |

| Securities Available for Sale | Securities Available for Sale Quarterly, Trustmark evaluates if any security has a fair value less than its amortized cost. Once these securities are identified, in order to determine whether a decline in fair value resulted from a credit loss or other factors, Trustmark performs further analysis. If Trustmark determines that a credit loss exists, the credit portion of the allowance is measured using a DCF analysis using the effective interest rate as of the security’s purchase date. The amount of credit loss Trustmark records will be limited to the amount by which the amortized cost exceeds the fair value. The DCF analysis utilizes contractual maturities, as well as third-party credit ratings and cumulative default rates published annually by Moody’s. At both December 31, 2024 and 2023, the results of the loss analysis performed did not identify any securities that warranted DCF analysis and no credit loss was recognized on any of the securities available for sale. Accrued interest receivable is excluded from the estimate of credit losses for securities available for sale. At December 31, 2024 and 2023, accrued interest receivable totaled $5.0 million and $3.7 million, respectively, for securities available for sale and was reported in other assets on the accompanying consolidated balance sheet. |

| Securities Held to Maturity | Securities Held to Maturity At December 31, 2024, Trustmark identified no securities held to maturity with the potential for credit loss exposure, compared to $340 thousand at December 31, 2023, which consisted of municipal securities. After applying appropriate probability of default and loss given default assumptions, the total amount of current expected credit losses was zero at December 31, 2024 and immaterial at December 31, 2023. Therefore, no reserve was recorded at either December 31, 2024 or December 31, 2023. Accrued interest receivable is excluded from the estimate of credit losses for securities held to maturity. At December 31, 2024 and 2023, accrued interest receivable totaled $2.4 million and $2.6 million for securities held to maturity and was reported in other assets on the accompanying consolidated balance sheet. At both December 31, 2024 and 2023, Trustmark had no securities held to maturity that were past due 30 days or more as to principal or interest payments. Trustmark had no securities held to maturity classified as nonaccrual at December 31, 2024 and 2023. |
