You can identify forward-looking statements by words such as “may,” “hope,” “will,” “should,” “expect,” “plan,” “anticipate,” “intend,” “believe,” “estimate,” “predict,” “project,” “potential,” “seek,” “continue,” “could,” “would,” “future” or the negative of those terms or other words of similar meaning. You should read statements that contain these words carefully because they discuss our future expectations or state other “forward-looking” information. These forward-looking statements include, but are not limited to, statements relating to anticipated future operating and financial performance measures, including net interest margin, credit quality, business initiatives, growth opportunities and growth rates, among other things, and encompass any estimate, prediction, expectation, projection, opinion, anticipation, outlook or statement of belief included therein as well as the management assumptions underlying these forward-looking statements. You should be aware that the occurrence of the events described under the caption “Risk Factors” in Trustmark’s filings with the Securities and Exchange Commission (SEC) could have an adverse effect on our business, results of operations and financial condition. Should one or more of these risks materialize, or should any such underlying assumptions prove to be significantly different, actual results may vary significantly from those anticipated, estimated, projected or expected.

Risks that could cause actual results to differ materially from current expectations of Management include, but are not limited to, changes in the level of nonperforming assets and charge-offs, an increase in unemployment levels and slowdowns in economic growth, actions by the Board of Governors of the Federal Reserve System (FRB) that impact the level of market interest rates, local, state and national economic and market conditions, conditions in the housing and real estate markets in the regions in which Trustmark operates and the extent and duration of the current volatility in the credit and financial markets, levels of and volatility in crude oil prices, changes in our ability to measure the fair value of assets in our portfolio, material changes in the level and/or volatility of market interest rates, the impacts related to or resulting from recent bank failures and other economic and industry volatility, including potential increased regulatory requirements and costs and potential impacts to macroeconomic conditions, the performance and demand for the products and services we offer, including the level and timing of withdrawals from our deposit accounts, the costs and effects of litigation and of unexpected or adverse outcomes in such litigation, our ability to attract noninterest-bearing deposits and other low-cost funds, competition in loan and deposit pricing, as well as the entry of new competitors into our markets through de novo expansion and acquisitions, economic conditions, including the potential impact of issues related to the European financial system and monetary and other governmental actions designed to address credit, securities, and/or commodity markets, the enactment of legislation and changes in existing regulations or enforcement practices or the adoption of new regulations, changes in accounting standards and practices, including changes in the interpretation of existing standards, that affect our consolidated financial statements, changes in consumer spending, borrowings and savings habits, technological changes, changes in the financial performance or condition of our borrowers, changes in our ability to control expenses, greater than expected costs or difficulties related to the integration of acquisitions or new products and lines of business, cyber-attacks and other breaches which could affect our information system security, natural disasters, environmental disasters, pandemics or other health crises, acts of war or terrorism, and other risks described in our filings with the SEC.

Although we believe that the expectations reflected in such forward-looking statements are reasonable, we can give no assurance that such expectations will prove to be correct. Except as required by law, we undertake no obligation to update or revise any of this information, whether as the result of new information, future events or developments or otherwise.

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 accompanying unaudited condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the consolidated financial statements, and notes thereto, included in Trustmark’s Annual Report on Form 10-K for its fiscal year ended December 31, 2022 (2022 Annual Report).

Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period. In the opinion of Management, all adjustments (consisting of normal recurring accruals) considered necessary for the fair presentation of these consolidated financial statements have been included. 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 2023 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.

During 2022, Trustmark reclassified a total of $766.0 million of securities available for sale to securities held to maturity. At 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 September 30, 2023, the net unamortized, unrealized loss on transferred securities included in accumulated other comprehensive income (loss) in the accompanying balance sheet totaled $60.4 million compared to $69.2 million at December 31, 2022.

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 discounted cash flow (DCF) analysis using the effective interest rate as of the security’s purchase date. The amount of credit loss recorded by Trustmark is 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).

At both September 30, 2023 and December 31, 2022, the results of the analysis 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 September 30, 2023, accrued interest receivable totaled $3.6 million for securities available for sale compared to $4.0 million at December 31, 2022 and was reported in other assets on the accompanying consolidated balance sheet.

Securities Held to Maturity

At September 30, 2023 and December 31, 2022, the potential for credit loss exposure for Trustmark's securities held to maturity was $341 thousand and $4.5 million, respectively, and consisted of municipal securities. After applying appropriate probability of default (PD) and loss given default (LGD) assumptions, the total amount of current expected credit losses was deemed immaterial. Therefore, no reserve was recorded at September 30, 2023 and December 31, 2022.

10

Accrued interest receivable is excluded from the estimate of credit losses for securities held to maturity. At September 30, 2023, accrued interest receivable totaled $2.6 million for securities held to maturity compared to $2.7 million at December 31, 2022 and was reported in other assets on the accompanying consolidated balance sheet.

At both September 30, 2023 and December 31, 2022, 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 September 30, 2023 and December 31, 2022.

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 September 30, 2023 and December 31, 2022 ($ in thousands):

	September 30, 2023		December 31, 2022

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

During the nine months ended September 30, 2023 and 2022, there were no gross realized gains or losses as a result of calls and dispositions of securities. Realized gains and losses are determined using the specific identification method and are included in noninterest income as securities gains (losses), net.

Securities Pledged

Securities with a carrying value of $2.389 billion and $2.693 billion at September 30, 2023 and December 31, 2022, respectively, were pledged to collateralize public deposits and securities sold under repurchase agreements and for other purposes as permitted by law. At both September 30, 2023 and December 31, 2022, 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 September 30, 2023, 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.

Accrued interest receivable is not included in the amortized cost basis of Trustmark’s LHFI. At September 30, 2023 and December 31, 2022, accrued interest receivable for LHFI totaled $64.3 million and $50.7 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 September 30, 2023, Trustmark’s geographic loan distribution was concentrated primarily in its five key market regions: Alabama, Florida, 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.

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.

Trustmark had no unused commitments on modified loans to borrowers experiencing financial difficulty at September 30, 2023.

During the nine months ended September 30, 2023, Trustmark had term extension balances of $108 thousand at default for LHFI in the loans secured by 1-4 family residential properties 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):

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. There have been no 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. One credit relationship experienced a decline in fair value due to general deterioration during the quarter to the collateral that secures the relationship. 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 – Loans within this loan class are secured by non-real estate collateral. One loan relationship experienced a decline in fair value due to general deterioration during the quarter to the assets that secure the relationship. There have been no other 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 an 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 the bank regulatory agencies and are generally equally applied to each individual lending institution. The remaining credit risk grades are considered pass credits and are solely defined by Trustmark.

18

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 $100 thousand or more.

In addition, periodic reviews of significant development, commercial construction, multi-family and nonowner-occupied projects 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 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

Consumer LHFI that do not meet a minimum custom credit score are reviewed quarterly. The Retail Credit Review Committee, Management Credit Policy Committee and the Enterprise Risk Committee review the volume and/or percentage of approvals that did not meet the minimum passing custom score to ensure that Trustmark continues to originate quality loans.

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.

Past Due LHFS

LHFS past due 90 days or more totaled $42.5 million and $49.3 million at September 30, 2023 and December 31, 2022, respectively. LHFS past due 90 days or more are serviced loans eligible for repurchase, which are fully guaranteed by the Government National Mortgage Association (GNMA). 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% of the remaining principal balance of the loan. 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 loans held for sale, regardless of whether Trustmark intends to exercise the buy-back option. These loans are reported as held for sale with the offsetting liability being reported as short-term borrowings.

Trustmark did not exercise its buy-back option on any delinquent loans serviced for GNMA during the first nine months of 2023 or 2022.

ACL on LHFI

Trustmark’s ACL methodology for LHFI is based upon guidance within the Financial Accounting Standards Board (FASB) Accounting Standards Codification (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 a credit 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 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.

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

27

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 the first quarter of 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.

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 its assets, as required by FASB ASC Topic 326. Under stable forecasts, these linear regressions will reasonably predict a pool’s PD. However, due to the COVID-19 pandemic, the macroeconomic variables used for reasonable and supportable forecasting changed rapidly. At the macroeconomic levels experienced during the COVID-19 pandemic, it is not clear that the models currently in production will produce reasonably representative results since the models 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), Southern GDP, Southern Vacancy Rate and the Prime Rate. 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. Due to multiple periods having 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

28

•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: (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.

For the performance trends factor, Trustmark uses migration analyses to allocate 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 nature and volume of the portfolio qualitative factor utilizes peer and industry assumptions for pools of loans where Trustmark’s historical experience might not capture the risk associated within a specific pool due to it being a different type of lending, different sources of repayment or a new line of business.

The external factors qualitative factor is Management’s best judgement 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). Trustmark's External Factor – Pandemic ensures reserve adequacy for collectively evaluated loans most likely to be impacted by the unique economic and behavioral conditions created by the COVID-19 pandemic. Additional qualitative reserves are derived based on two principles. The first is the disconnect of economic factors to Trustmark’s modeled PD (derived from the econometric models underpinning the quantitative pooled reserves). During the pandemic, extraordinary measures by the federal government were made available to consumers and businesses, including COVID-19 loan payment concessions, direct transfer payments to households, tax deferrals, and reduced interest rates, among others. These government interventions may have extended the lag between economic conditions and default, relative to what was captured in the model development data. Because Trustmark’s econometric PD models rely on the observed relationship from the economic downturn from 2007 to 2009 in both timing and severity, Management does not expect the models to reflect these current conditions. For example, while the models would predict contemporaneous unemployment peaks and loan defaults, this may not occur when borrowers can request payment deferrals. Thus, for the affected population, economic conditions are not fully considered as a part of Trustmark’s quantitative reserve. The second principle is the change in risk that is identified by rating changes. As a part of Trustmark’s credit review process, loans in the affected population have been given more frequent screening to ensure accurate ratings are maintained through this dynamic period. Trustmark’s quantitative reserve does not directly address changes in ratings, thus a migration qualitative factor was designed to work in concert with the quantitative reserve.

As discussed above, the disconnect of economic factors means that changes in rating caused by deteriorating and weak economic conditions as a result of the pandemic were not being captured in the quantitative reserve. During 2020, due to unforeseen pandemic conditions that varied from Management’s expectations, additional reserves were further dimensioned in order to appropriately reflect the risk within the portfolio related to the COVID-19 pandemic. In an effort to ensure the External Factor-Pandemic qualitative factor is reasonable and supportable, historical Trustmark loss data was leveraged to construct a framework that is quantitative in nature. To dimension the additional reserve, Management uses the sensitivity of the quantitative commercial loan reserve to changes in macroeconomic conditions to apply to loans rated acceptable or better (RR 1-4). In addition, to account for the known changes in risk, a weighted average of the commercial loan portfolio loss rate, derived from the performance trends qualitative factor, is used to dimension additional reserves for downgraded credits. Loans rated acceptable with risk (RR 5) or watch (RR 6) received the additional reserves based on the average of the macroeconomic conditions and weighted-average of the commercial loan portfolio loss rate while the loans rated special mention and substandard received additional reserves based on the weighted-average described above. During the fourth quarter of 2022, Management noted that all pass rated loans (RR 5 & RR 6) related to the External Factor-Pandemic qualitative factor either did not experience significant stress related to the pandemic or have since recovered and does not expect future stresses attributed to the pandemic that may affect these loans. As a result, Management decided to accelerate the release of the additional pandemic reserves on all pass rated loans.

During the first quarter of 2022, in order to account for the potential uncertainty related to higher prices and low economic growth, Trustmark chose to enact a portion of the qualitative framework, External Factor - Stagflation. Management calculated the reserve using a third-party stagflation forecast and compared it to the third-party baseline forecast used in the quantitative modeling. The weighted differential is added as qualitative reserves to account for potential uncertainty. During the fourth quarter of 2022, Management determined that the likelihood of a stagflation scenario had sufficiently diminished. Management identified that the potential had already been reduced and effectively captured within a nominally more negative baseline economic forecast. As a result, Management elected to resolve the External Factor - Stagflation and fully release the reserves.

The increases in the PCL, LHFI for the nine months ended September 30, 2022 primarily due to loan growth, the nature and volume of the portfolio, and specific reserves for individually analyzed loans.

For the nine months ended September 30, 2022, the decreases in the PCL, LHFI for the secured by nonfarm, nonresidential properties and other real estate secured loan portfolios was primarily due to a positive economic outlook and the initial stages of resolution of the External Factor- Pandemic qualitative factor. The decrease in the PCL, LHFI for the state and other political subdivision loans portfolio was due to routine modeling assumption updates.

Note 4 – Mortgage Banking

MSR

The activity in the MSR is detailed in the table below for the periods presented ($ in thousands):

	Nine Months Ended September 30,
	2023			2022
Balance at beginning of period	$	129,677		$	87,687
Origination of servicing assets		11,025			14,452
Change in fair value:
Due to market changes		8,735			41,529
Due to run-off		(7,058	)		(11,053	)
Balance at end of period	$	142,379		$	132,615

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 September 30, 2023, the fair value of the MSR included an assumed average prepayment speed of 8 CPR and an average discount rate of 10.07% compared to an assumed average prepayment speed of 8 CPR and an average discount rate of 9.58% at September 30, 2022.

Mortgage Loans Serviced/Sold

During the first nine months of 2023 and 2022, Trustmark sold $893.0 million and $1.026 billion, respectively, of residential mortgage loans. Gains on these sales were recorded as noninterest income in mortgage banking, net and totaled $11.4 million for the first nine months of 2023 compared to $16.9 million for the first nine months of 2022.

The table below details the mortgage loans sold and serviced for others at September 30, 2023 and December 31, 2022 ($ in thousands):

	September 30, 2023		December 31, 2022
Federal National Mortgage Association	$	4,802,861	$	4,684,815
Government National Mortgage Association		3,478,965		3,350,222
Federal Home Loan Mortgage Corporation		90,119		52,023
Other		31,440		28,764
Total mortgage loans sold and serviced for others	$	8,403,385	$	8,115,824

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 September 30, 2023 and 2022, Trustmark had a reserve for mortgage loan servicing putback expenses of $500 thousand.

33

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.

Note 5 – Other Real Estate

At September 30, 2023, Trustmark’s geographic other real estate distribution was primarily concentrated in its Texas and Mississippi market regions.

Trustmark utilizes securities sold under repurchase agreements as a source of borrowing in connection with overnight repurchase agreements offered to commercial deposit customers by using its unencumbered investment securities as collateral. Trustmark accounts for its securities sold under repurchase agreements as secured borrowings in accordance with FASB ASC Subtopic 860-30, “Transfers and Servicing – Secured Borrowing and Collateral.” Securities sold under repurchase agreements are stated at the amount of cash received in connection with the transaction. Trustmark monitors collateral levels on a continual basis and may be required to provide additional collateral based on the fair value of the underlying securities. Securities sold under repurchase agreements were secured by securities with a carrying amount of $61.0 million and $102.4 million at September 30, 2023 and December 31, 2022, respectively. Trustmark’s repurchase agreements are transacted under master repurchase agreements that give Trustmark, in the event of default by the counterparty, the right of offset with the same counterparty. At both September 30, 2023 and December 31, 2022, all repurchase agreements were short-term and consisted primarily of sweep repurchase arrangements, under which excess deposits are “swept” into overnight repurchase agreements with Trustmark. The following table presents the securities sold under repurchase agreements by collateral pledged at September 30, 2023 and December 31, 2022 ($ in thousands):

Note 9 – 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 income, 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 real estate expense, are also within the scope of FASB ASC Topic 606.

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, net. Other real estate sales for the three months ended September 30, 2023 result in a net loss of $47 thousand compared to a net loss of $11 thousand for the three months ended September 30, 2022. Other real estate sales for the nine months ended September 30, 2023 resulted in a net loss of $159 thousand compared to a net loss of $465 thousand for the nine months ended September 30, 2022.

Note 10 – 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 table presents information regarding the net periodic benefit cost for the Continuing Plan for the periods presented ($ in thousands):

For the plan year ending December 31, 2023, Trustmark’s minimum required contribution to the Continuing Plan is $159 thousand; however, Management and the Board of Directors of Trustmark will monitor the Continuing Plan throughout 2023 to determine any additional funding requirements by the plan’s measurement date, which is December 31.

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 table presents information regarding the net periodic benefit cost for Trustmark’s nonqualified supplemental retirement plans for the periods presented ($ in thousands):

Note 11 – Stock and Incentive Compensation

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.

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 was 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 provide for achievement units if performance measures exceed 100%. The restricted stock agreement for these units provide for dividend privileges, but no voting rights.

Time-Based Units

Trustmark’s time-based units granted to Trustmark’s executive and senior management teams vest over three years. Trustmark’s time-based units granted to members of Trustmark’s Board of Directors vest over one year. Time-based units are valued utilizing the fair value of Trustmark’s stock at the grant date. These units are recognized on the straight-line method over the requisite service period. The restricted stock agreement for these units provide for dividend privileges, but no voting rights.

The following tables summarize the Stock Plan activity for the periods presented:

Note 12 – 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 September 30, 2023 and 2022, Trustmark had unused commitments to extend credit of $5.030 billion and $5.171 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 September 30, 2023 and 2022, Trustmark’s maximum exposure to credit loss in the event of nonperformance by the customer for letters of credit was $127.8 million and $140.6 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. As of September 30, 2023 and 2022, the fair value of collateral held was $32.0 million and $32.6 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 sheet as of September 30, 2023 and December 31, 2022.

Changes in the ACL on off-balance sheet credit exposures were as follows for the periods presented ($ in thousands):

	Three Months Ended September 30,					Nine Months Ended September 30,
	2023		2022			2023			2022
Balance at beginning of period	$	34,841	$	32,949		$	36,838		$	35,623
PCL, off-balance sheet credit exposures		104		(1,326	)		(1,893	)		(4,000	)
Balance at end of period	$	34,945	$	31,623		$	34,945		$	31,623

Adjustments to the ACL on off-balance sheet credit exposures are recorded to PCL, off-balance sheet credit exposures. The increase in the ACL on off-balance sheet credit exposures for the three months ended September 30, 2023 was primarily due to the weakening

40

macroeconomic forecasts as well as the net adjustment to the qualitative factors. The decrease in the ACL on off-balance sheet credit exposures for the nine months ended September 30, 2023 was primarily due to decreases in unfunded balances for the construction, land development and other land portfolio and other construction loan portfolio. The decrease in the ACL on off-balance sheet credit exposures for the three and nine months ended September 30, 2022 was primarily due to a decrease in the unfunded balances.

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.

Legal Proceedings

Trustmark’s wholly-owned subsidiary, TNB, has been named as a defendant in several lawsuits related to the collapse of the Stanford Financial Group.

On August 23, 2009, a purported class action complaint was filed in the District Court of Harris County, Texas, by Peggy Roif Rotstain, Guthrie Abbott, Catherine Burnell, Steven Queyrouze, Jaime Alexis Arroyo Bornstein and Juan C. Olano (collectively, Class Plaintiffs), on behalf of themselves and all others similarly situated, naming TNB and four other financial institutions and one individual, each of which are unaffiliated with Trustmark, as defendants (the Rotstain Action). The complaint sought to recover (i) alleged fraudulent transfers from each of the defendants in the amount of fees and other monies received by each defendant from entities controlled by R. Allen Stanford (collectively, the Stanford Financial Group) and (ii) damages allegedly attributable to alleged conspiracies by one or more of the defendants with the Stanford Financial Group to commit fraud and/or aid and abet fraud on the asserted grounds that defendants knew or should have known the Stanford Financial Group was conducting an illegal and fraudulent scheme.

In November 2009, the lawsuit was removed to federal court by certain defendants and then transferred by the United States Panel on Multidistrict Litigation to the United States District Court for the Northern District of Texas (Dallas), where multiple Stanford related matters have been consolidated for pre-trial proceedings. In May 2010, all defendants (including TNB) filed motions to dismiss the lawsuit. In August 2010, the court authorized and approved the formation of an Official Stanford Investors Committee (OSIC) to represent the interests of Stanford investors and, under certain circumstances, to file legal actions for the benefit of Stanford investors. In December 2011, the OSIC filed a motion to intervene in this action, which was granted in December 2012. The OSIC initially sought to recover from TNB and the other defendant financial institutions: (i) alleged fraudulent transfers in the amount of the fees each of the defendants allegedly received from Stanford Financial Group, the profits each of the defendants allegedly made from Stanford Financial Group deposits, and other monies each of the defendants allegedly received from Stanford Financial Group; (ii) damages attributable to alleged conspiracies by each of the defendants with the Stanford Financial Group to commit fraud and/or aid and abet fraud and conversion on the asserted grounds that the defendants knew or should have known the Stanford Financial Group was conducting an illegal and fraudulent scheme; and (iii) punitive damages.

In July 2013, all defendants (including TNB) filed motions to dismiss the OSIC’s claims. In March 2015, the court entered an order authorizing the parties to conduct discovery regarding class certification, staying all other discovery and setting a deadline for the parties to complete briefing on class certification issues. In April 2015, the court granted in part and denied in part the defendants’ motions to dismiss the Class Plaintiffs’ claims and the OSIC’s claims. The court dismissed all of the Class Plaintiffs’ fraudulent transfer claims and dismissed certain of the OSIC’s claims. The court denied the motions by TNB and the other financial institution defendants to dismiss the OSIC’s constructive fraudulent transfer claims.

On June 23, 2015, the court allowed the Class Plaintiffs to file a Second Amended Class Action Complaint (SAC), which asserted new claims against TNB and certain of the other defendants for (i) aiding, abetting and participating in a fraudulent scheme, (ii) aiding, abetting and participating in violations of the Texas Securities Act, (iii) aiding, abetting and participating in breaches of fiduciary duty, (iv) aiding, abetting and participating in conversion and (v) conspiracy. On July 14, 2015, the defendants (including TNB) filed motions to dismiss the SAC and to reconsider the court’s prior denial to dismiss the OSIC’s constructive fraudulent transfer claims against TNB and the other financial institutions that are defendants in the action. On July 27, 2016, the court denied the motion by TNB and the other financial institution defendants to dismiss the SAC and also denied the motion by TNB and the other financial institution defendants to reconsider the court’s prior refusal to dismiss the OSIC’s constructive fraudulent transfer claims. On August 24, 2016, TNB filed its answer to the SAC. On October 20, 2017, the OSIC filed a motion seeking an order lifting the discovery stay and establishing a trial schedule. On November 4, 2016, the OSIC filed a First Amended Intervenor Complaint, which added claims for (i) aiding, abetting or participation in violations of the Texas Securities Act and (ii) aiding, abetting or participation in the breach of fiduciary duty. On November 7, 2017, the court denied the Class Plaintiffs’ motion seeking class certification and designation of class representatives and counsel, finding that common issues of fact did not predominate. The court granted the OSIC’s motion to lift the discovery stay that it had previously ordered.

On May 3, 2019, individual investors and entities filed motions to intervene in the action. On September 18, 2019, the court denied the motions to intervene. On October 14, 2019, certain of the proposed intervenors filed a notice of appeal. On February 3, 2021, the Fifth

41

Circuit Court of Appeals affirmed the denial of the motions to intervene; this decision was affirmed by a panel of the Fifth Circuit on March 12, 2021.

On February 12, 2021, all defendants (including TNB) filed a motion for summary judgment with respect to OSIC claims that applied to all defendants. In addition, on the same date, TNB filed a separate motion for summary judgment with respect to aspects of OSIC claims that applied specifically to TNB. On March 19, 2021, OSIC filed notice with the court that it was abandoning as against all of the defendants (including TNB) certain of the claims previously set forth in the SAC. As a result, only the claims for (i) aiding, abetting and participating in breaches of fiduciary duty, (ii) aiding, abetting and participating in violations of the Texas Securities Act, and (iii) punitive damages remained as against TNB. On January 20, 2022, the court denied TNB’s motion for summary judgment, as well as the motion for summary judgment filed by all defendants (including TNB) with respect to OSIC claims that apply to all defendants.

The parties to the action agreed that the case was to be tried in the District Court for the Southern District of Texas. On March 25, 2021, the District Court for the Northern District of Texas rescinded its previously-issued trial scheduling orders so that the Southern District of Texas could set scheduling for this case once the case had in fact been remanded. On January 19, 2022, the judge of the District Court for the Northern District of Texas to whom the case was then assigned issued a recommendation to the Judicial Panel on Multidistrict Litigation (the Panel) that the case be remanded to the District Court for the Southern District of Texas in light of the judge’s determination with respect to the summary judgment motions that triable issues of fact exist. On January 21, 2022, the Panel approved the remand of the case to the District Court for the Southern District of Texas, and on January 28, 2022 the remand of the case became effective. On June 9, 2022, the court entered an order scheduling trial to begin February 27, 2023, which was to be held as a jury trial in front of Judge Kenneth M. Hoyt of the District Court for the Southern District of Texas.

On December 14, 2009, a different Stanford-related lawsuit was filed in the District Court of Ascension Parish, Louisiana, individually by Harold Jackson, Paul Blaine and Carolyn Bass Smith, Christine Nichols, and Ronald and Ramona Hebert naming TNB (misnamed as Trust National Bank) and other individuals and entities not affiliated with Trustmark as defendants (the Jackson Action). The complaint seeks to recover the money lost by these individual plaintiffs as a result of the collapse of the Stanford Financial Group (in addition to other damages) under various theories and causes of action, including negligence, breach of contract, breach of fiduciary duty, negligent misrepresentation, detrimental reliance, conspiracy, and violation of Louisiana’s uniform fiduciary, securities, and racketeering laws. The complaint does not quantify the amount of money the plaintiffs seek to recover. In January 2010, the lawsuit was removed to federal court by certain defendants and then transferred by the United States Panel on Multidistrict Litigation to federal court in the Northern District of Texas (Dallas) where multiple Stanford related matters are being consolidated for pre-trial proceedings. On March 29, 2010, the court stayed the case. TNB filed a motion to lift the stay, which was denied on February 28, 2012. In September 2012, the district court referred the case to a magistrate judge for hearing and determination of certain pretrial issues.

On April 11, 2016, Trustmark learned that a different Stanford-related lawsuit had been filed on that date in the Superior Court of Justice in Ontario, Canada, by The Toronto-Dominion Bank (TD Bank), naming TNB and three other financial institutions not affiliated with Trustmark as defendants (the TD Bank Declaratory Action). The complaint seeks a declaration specifying the degree to which each of TNB and the other defendants are liable in respect of any loss and damage for which TD Bank is found to be liable in separate litigation commenced against TD Bank brought by the joint liquidators of Stanford International Bank Limited in the Superior Court of Justice, Commercial List in Ontario, Canada (the Joint Liquidators’ Action), as well as contribution and indemnity in respect of any judgment, interest and costs TD Bank is ordered to pay in the Joint Liquidators’ Action. Trustmark understands that on or about June 8, 2021, after an extensive trial on the merits, the judge in the Joint Liquidators’ Action ruled in favor of TD Bank and found TD Bank not liable as to the claims asserted against the bank by the joint liquidators of Stanford International Bank Limited. The plaintiffs in the Joint Liquidators’ Action appealed this decision. On November 17, 2022, the intermediate appellate court in Canada dismissed the appeal. On January 16, 2023, the plaintiffs in the Joint Liquidators’ Action filed an application with the Supreme Court of Canada for leave to appeal, which the Supreme Court of Canada dismissed on July 20, 2023. TNB was never served in connection with the TD Bank Declaratory Action (including any of the appeals), and thus has not made an appearance in that action.

On November 1, 2019, TNB was named as a defendant in a complaint filed by Paul Blaine Smith, Carolyn Bass Smith and other plaintiffs identified therein (the Smith Action and, collectively with the Rotstain Action and the Jackson Action, the Actions). The Smith Action was filed in Texas state court (District Court, Harris County, Texas) and named TNB and four other financial institutions and one individual, each of which are unaffiliated with Trustmark, as defendants. The Smith Action relates to the collapse of the Stanford Financial Group, as does the other pending litigation relating to Stanford summarized above. Plaintiffs in the Smith Action demanded a jury trial. On January 15, 2020, the court granted Stanford Financial Group receiver’s motion to stay the Texas state court action. On February 26, 2020, the lawsuit was removed to federal court in the Southern District of Texas by TNB.

On December 31, 2022, TNB agreed to a settlement in principle (the Stanford Settlement) relating to litigation involving the Stanford Financial Group. On January 13, 2023, TNB entered into a Settlement Agreement (the Stanford Settlement Agreement) reflecting the terms of the Stanford Settlement. The parties to the Stanford Settlement Agreement are, on the one hand, (i) Ralph S. Janvey, solely in his capacity as the court-appointed receiver (the Stanford Receiver) for the Stanford Receivership Estate; (ii) the Official Stanford

42

Investors Committee; (iii) each of the plaintiffs in the Rotstain and Smith Actions; and, on the other hand, (iv) Trustmark. Under the terms of the Stanford Settlement Agreement, the parties agreed to settle and dismiss the Rotstain Action, the Smith Action, and all current or future claims by plaintiffs in either such Action arising from or related to Stanford. In addition, the Stanford Settlement Agreement provided that the parties would request dismissal of the Jackson Action pursuant to the terms of the bar orders described below. If the Court’s approval (as described below) of the Stanford Settlement Agreement, including the bar orders described below, is upheld on appeal, Trustmark will make a one-time cash payment of $100.0 million to the Stanford Receiver.

The Stanford Settlement Agreement included the parties’ agreement to seek the Northern District of Texas District Court’s entry of bar orders prohibiting any continued or future claims by the plaintiffs in the Actions or by any other person or entity against Trustmark and its related parties relating to Stanford, whether asserted to date or not. The bar orders therefore would prohibit all litigation relating to Stanford described herein, including not only the Actions and any pending matters but also any actions that may be brought in the future. Final Court approval of these bar orders is a condition of the Stanford Settlement.

The Stanford Settlement Agreement is also subject to notice to Stanford’s investor claimants (which has been provided) and final, non-appealable approval by the U.S. District Court for the Northern District of Texas. While Trustmark believes that the Stanford Settlement Agreement is consistent with the terms of prior Stanford-related settlements that have been approved by the Court and were not successfully appealed, it is possible that the Court’s approval of the Stanford Settlement Agreement (which has occurred, as described further below) may not be upheld on appeal.

The Stanford Settlement Agreement also provides that Trustmark denies and makes no admission of liability or wrongdoing in connection with any Stanford matter. As has been the case throughout the pendency of the Actions, Trustmark expressly denies any liability or wrongdoing with respect to any matter alleged in regard to the multi-billion-dollar Ponzi scheme operated by Stanford for almost 20 years. Trustmark’s relationship with Stanford began as a result of Trustmark’s acquisition of a Houston-based bank in August 2006, and consisted of ordinary banking services provided to business deposit customers.

The foregoing description of the terms of the Stanford Settlement Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Stanford Settlement Agreement, a copy of which is filed as Exhibit 10.ai to the 2022 Annual Report and is incorporated herein by reference.

On January 20, 2023, the U.S. District Court for the Northern District of Texas entered an order preliminarily finding that the Stanford Settlement is fair, reasonable, and equitable; has no obvious deficiencies; and is the product of serious, informed, good faith, and arm’s-length negotiations. Following the provision of notice as required by the Stanford Settlement Agreement and by the Court’s preliminary order, the Court (Judge David C. Godbey, presiding) held a Final Approval Hearing on May 3, 2023, at which the Court approved the Stanford Settlement from the bench. On May 4, 2023, Judge Godbey signed the written orders confirming his oral ruling, including the bar order contemplated by the Stanford Settlement Agreement and the judgment and bar order with respect to the Jackson Action.

On May 10, 2023, Robert Allen Stanford, writing from prison, appealed the District Court’s approval of the Stanford Settlement to the Fifth Circuit Court of Appeals. On June 12, 2023, the Stanford Receiver moved to dismiss the appeal as frivolous. On July 25, 2023, a three-judge panel of the Fifth Circuit issued a per curiam order dismissing Stanford’s appeal as frivolous. On August 8, 2023, Mr. Stanford filed a motion for stay of mandate pending petition for certiorari. On August 22, 2023, the Fifth Circuit denied the motion for stay of mandate. On August 30, 2023, the Fifth Circuit issued the mandate.

The Stanford Settlement will become effective when the trial court’s ruling approving the Stanford Settlement and entering the bar order becomes final and non-appealable, as defined in the Stanford Settlement Agreement (the Stanford Settlement Effective Date). Within five days of the Stanford Settlement Effective Date, the parties to the Rotstain and Smith Actions will file agreed dismissals of those cases. Absent any further appeal in either of the Rotstain or Smith Actions, those dismissals will become final 30 days after entered and signed by the respective judges. Trustmark will be required to make the Stanford Settlement payment within 16 days after those dismissals become final. Any further appeal of any of the orders described above would delay the making of the Stanford Settlement payment.

On August 11, 2023, the Stanford Receiver filed a Motion to Enforce Settlement Agreement in the Northern District of Texas District Court, asking Judge Godbey to rule that the Stanford Settlement Effective Date has occurred. The Stanford Receiver took the position that Mr. Stanford’s appeals are frivolous and do not prevent the trial court’s ruling from becoming final and non-appealable, as defined in the Stanford Settlement Agreement. Trustmark filed a response in opposition to the Stanford Receiver’s Motion to Enforce. The trial court has not yet ruled on the Motion to Enforce. On September 22, 2023, the Stanford Receiver filed a Motion to Enjoin, requesting that the trial court enjoin Mr. Stanford from making court filings in any Stanford-related case, including notices of appeal, without obtaining leave of the court. The court has not yet ruled on the Motion to Enjoin.

Pending the resolution of the Stanford Settlement approval process, the Rotstain, Smith and Jackson Actions are stayed.

On December 30, 2019, a complaint was filed in the United States District Court for the Southern District of Mississippi, Northern Division by Alysson Mills in her capacity as Court-appointed Receiver (the Adams/Madison Timber Receiver) for Arthur Lamar Adams and Madison Timber Properties, LLC (collectively, Adams/Madison Timber), naming TNB, two other Mississippi-based financial institutions both of which are unaffiliated with TNB and two individuals, one of who was employed by TNB at all times relevant to the complaint and the other was employed either by TNB or one of the other defendant financial institutions, as defendants (the Adams/Madison Timber Action). The complaint seeks to recover from the defendants, for the benefit of the receivership estate and also for certain investors who were allegedly defrauded by Adams/Madison Timber, damages (including punitive damages) and related costs allegedly attributable to actions of the defendants that allegedly enabled illegal and fraudulent activities engaged in by Adams/Madison Timber. The Adams/Madison Timber Receiver did not quantify damages. By order issued by the court on September 30, 2021, the action to which TNB is a party was consolidated with three other pending cases for purposes of discovery, based upon a finding by the court that the actions involve overlapping questions of law and fact.

TNB’s relationship with Adams/Madison Timber consisted of traditional banking services in the ordinary course of business.

TNB and its subsidiaries are also parties to other 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.

On August 30, 2023, TNB agreed to a settlement in principle (the Adams/Madison Timber Settlement) relating to litigation and claims involving Arthur Lamar Adams and Madison Timber Properties, LLC ( collectively, Adams/Madison Timber). On October 9, 2023, TNB entered into a Settlement Agreement (the Adams/Madison Timber Settlement Agreement) reflecting the terms of the Adams/Madison Timber Settlement. The parties to the Adams/Madison Timber Settlement are, on the one hand, Alysson Mills in her capacity as Court-appointed Receiver ( the Adams/Madison Timber Receiver); and, on the other hand, TNB. Under the terms of the Adams/Madison Timber Settlement Agreement, the parties agreed to settle and dismiss the Adams/Madison Timber Action, and the Adams/Madison Timber Receiver will fully release all claims against TNB and any of its employees, agents and representatives. The Adams/Madison Timber Settlement includes the parties’ agreement to seek the Court’s entry of bar orders prohibiting any continued or future claims by anyone against TNB and its related parties relating to Adams/Madison Timber, whether asserted to date or not. The bar orders therefore would prohibit all litigation relating to Adams/Madison Timber described herein. Final Court approval of a bar order is a condition of the Adams/Madison Timber Settlement.

The Adams/Madison Timber Settlement is also subject to notice to Adams/Madison Timber investors, and final, non-appealable approval by the Court and entry of a judgment dismissing the Lawsuit against TNB. The timing of any final decision by the Court is subject to the discretion of the Court and any appeal. If the Adams/Madison Timber Settlement, including the bar order described above, is approved by the Court and is not subject to further appeal, TNB will make a one-time cash payment of $6.5 million to the Adams/Madison Timber Receiver.

While TNB believes that the Adams/Madison Timber Settlement is consistent with the terms of settlements in similar cases that have been approved and were not successfully appealed, it is possible that the Court may decide not to approve the Adams/Madison Timber Settlement Agreement or that the Court of Appeals could reject the Adams/Madison Timber Settlement Agreement on an appeal, either of which could render the Adams/Madison Timber Settlement a nullity.

All pending legal proceedings described above are being vigorously contested, with the exception of the TD Bank Declaratory Action that, as noted above, TNB was not served in connection with. In accordance with FASB ASC Subtopic 450-20, “Loss Contingencies,” TNB will establish an accrued liability for any litigation matter if and when such matter presents loss contingencies that are both probable and reasonably estimable. As a result of the entry into the Stanford Settlement as described above, Trustmark Corporation recognized a $100.0 million litigation settlement expense included in noninterest expense related to the Stanford litigation during the fourth quarter of 2022, plus an additional $750 thousand in related legal fees. As a result of the entry into the Adams/Madison Timber Settlement as described above, Trustmark Corporation recognized a $6.5 million litigation settlement expense included in noninterest expense related to the Adams/Madison Timber litigation during the third quarter of 2023. Trustmark Corporation expects that both the Stanford Settlement and Adams/Madison Timber Settlement will be tax deductible. Trustmark Corporation and TNB will remain substantially above levels considered to be well-capitalized under all relevant standards. At the present time, TNB believes, based on its evaluation and the advice of legal counsel, that a loss in any currently pending legal proceeding other than the settled Stanford and Adams/Madison Timber litigation is not probable and a reasonable estimate cannot reasonably be made.

Note 15 – 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 Trustmark’s 2022 Annual 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 2.50%. Accumulated other comprehensive income (loss), net of tax, is not included in computing regulatory capital. Trustmark elected the five-year phase-in transition period (through December 31, 2024) related to adopting FASB ASU 2016-13 for regulatory capital purposes. 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. As of September 30, 2023, Trustmark and TNB exceeded all applicable minimum capital standards. In addition, Trustmark and TNB met applicable regulatory guidelines to be considered well-capitalized at September 30, 2023. To be categorized in this manner, Trustmark and TNB maintained, as applicable, 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 September 30, 2023, which Management believes have affected Trustmark’s or TNB’s present classification.

Note 16 – 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

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 September 30, 2023, 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 September 30, 2023, Trustmark had outstanding balances of $47.4 million with a related ACL of $15.0 million in collateral-dependent LHFI, compared to outstanding balances of $40.3 million with a related ACL of $17.7 million in collateral-dependent LHFI at December 31, 2022. 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 $765 thousand were remeasured during the first nine months of 2023, requiring write-downs of $205 thousand to reach their current fair values compared to $3.0 million of foreclosed assets that were remeasured during the first nine months of 2022, requiring write-downs of $1.0 million.

Fair Value of Financial Instruments

FASB ASC Topic 825, “Financial Instruments,” 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 September 30, 2023 and December 31, 2022, are as follows ($ in thousands):

Fair Value Option

Trustmark has elected to account for its mortgage LHFS under the fair value option, with interest income on these mortgage LHFS reported in interest and fees on LHFS and LHFI. The fair value of the mortgage LHFS is determined using quoted prices for a similar asset, adjusted for specific attributes of that loan. The mortgage 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 LHFS are largely offset by changes in the fair value of the derivative instruments. For the three and nine months ended September 30, 2023, net losses of $602 thousand and $841 thousand, respectively, were recorded as noninterest income in mortgage banking, net for changes in the fair value of LHFS accounted for under the fair value option, compared to net losses of $4.4 million and $6.7 million for the three and nine months ended September 30, 2022, respectively. Interest and fees on LHFS and LHFI for the three and nine months ended September 30, 2023 included $2.3 million and $5.9 million, respectively, of interest earned on LHFS accounted for under the fair value option, compared to $2.0 million and $5.2 million for the three and nine months ended September 30, 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 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 $63.7 million and $70.8 million at September 30, 2023 and December 31, 2022, respectively, and are included in LHFS on the accompanying consolidated balance sheets. For additional information regarding GNMA optional repurchase loans, please see the section captioned “Past Due LHFS” included in Note 3 – LHFI and ACL, LHFI.

The following table provides information about the fair value and the contractual principal outstanding of LHFS accounted for under the fair value option at September 30, 2023 and December 31, 2022 ($ in thousands):

Note 17 – Derivative Financial Instruments

Derivatives Designated as Hedging Instruments

During the third quarter of 2022, Trustmark initiated a cash flow hedging program. Trustmark's objectives in initiating this hedging program were 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 September 30, 2023, the aggregate notional value of Trustmark's interest rate swaps and floor spreads designated as cash flow hedges totaled $1.000 billion compared to $825.0 million at December 31, 2022.

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 totaled $13 thousand and $35 thousand of amortization expense for the three and nine months ended September 30, 2023, respectively, and are included in interest and fees on LHFS and LHFI. 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 $18.4 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.

52

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 $270.0 million at September 30, 2023 compared to $277.0 million at December 31, 2022. 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 $1.0 million and $928 thousand for the three months ended September 30, 2023 and 2022, respectively. For the nine months ended September 30, 2023 and 2022, the impact was a net negative ineffectiveness of $4.1 million and $554 thousand, 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 $133.0 million at September 30, 2023, with a positive valuation adjustment of $1.5 million, compared to $97.0 million, with a positive valuation adjustment of $168 thousand, at December 31, 2022.

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 $96.8 million at September 30, 2023, with a positive valuation adjustment of $197 thousand, compared to $68.4 million, with a positive valuation adjustment of $157 thousand, at December 31, 2022.

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 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 September 30, 2023, Trustmark had interest rate swaps with an aggregate notional amount of $1.365 billion related to this program, compared to $1.391 billion at December 31, 2022.

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 both September 30, 2023 and December 31, 2022, there was no 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. At September 30, 2023 and December 31, 2022, Trustmark had posted collateral of $40 thousand and $740 thousand, 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 September 30, 2023, 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 September 30, 2023 and December 31, 2022, Trustmark had entered into five risk participation agreements as a beneficiary with aggregate notional amounts of $49.1 million and $50.2 million, respectively. At September 30, 2023, Trustmark had entered into thirty-four risk participation agreements as a guarantor with an aggregate notional amount of $281.9 million compared to twenty-nine risk participation agreements as a guarantor with an aggregate notional amount of $235.8 million at December 31, 2022. The aggregate fair values of these risk participation agreements were immaterial at both September 30, 2023 and December 31, 2022.

Note 18 – Segment Information

Trustmark’s management reporting structure includes three segments: General Banking, Wealth Management and Insurance. For a complete overview of Trustmark’s operating segments, see Note 20 – Segment Information included in Part II. Item 8. – Financial Statements and Supplementary Data, of Trustmark’s 2022 Annual Report.

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.

Note 19 – Accounting Policies Recently Adopted and Pending Accounting Pronouncements

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 2022-02, “Financial Instruments-Credit Losses (Topic 326): Trouble Debt Restructurings and Vintage Disclosures.” Issued in March 2022, ASU 2022-02 seeks to improve the decision usefulness of information provided to investors concerning certain loan refinancings, restructurings and write-offs. In regard to troubled debt restructurings (TDRs) by creditors, investors and preparers observed that the additional designation of a loan modification as a TDR and the related accounting are unnecessarily complex and no longer provide decision-useful information. The amendments of ASU 2022-02 eliminate the accounting guidance for TDRs by creditors in FASB ASC Subtopic 310-40, “Receivables-Troubled Debt Restructurings by Creditors,” as it is no longer meaningful due to the implementation of FASB ASC Topic 326, which requires an entity to consider lifetime expected credit losses on loans when establishing an allowance for credit losses. Therefore, most losses that would have been realized for a TDR under FASB ASC Subtopic 310-40 are now captured by the accounting required under FASB ASC Topic 326. The amendments of ASU 2022-02 also enhanced disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Stakeholders also noted inconsistency in the requirement for a public business entity (PBE) to disclose gross write-offs and gross recoveries by class of financing receivable and major security type in certain vintage disclosures. Financial statement users expressed that, in addition to the existing vintage disclosures in FASB ASC Topic 326, information about gross write-offs by year of origination would be helpful in understanding credit quality changes in an entity’s loan portfolio and underwriting performance. For PBEs, the amendments of ASU 2022-02 require that an entity disclose current period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of FASB ASC Subtopic 326-20, “Financial Instruments-Credit Losses-Measured at Amortized Cost.” For write-offs associated with origination dates that are more than five annual periods before the reporting period, an entity may present aggregate amounts in the current period for financing receivables and net investment in leases. The amendments of ASU 2022-02 are effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2022 for entities that have already adopted the amendments of ASU 2016-13. Early adoption is permitted, provided that an entity has adopted ASU 2016-13. If an entity elects to early adopt the amendments of this ASU during an interim period, the guidance should be applied as of the beginning of the fiscal year that includes the interim period. In addition, an entity may elect to early adopt the amendments about TDRs and related disclosure enhancements separately from the amendments related to vintage disclosures. Trustmark adopted the amendments of ASU 2022-02 effective January 1, 2023. The amendments of ASU 2022-02 include only changes to certain financial statement disclosures; and, therefore, adoption of ASU 2022-02 did not have a material impact on Trustmark’s consolidated financial statements or results of operations. The enhanced disclosures required by ASU 2022-02 are presented in Note 3 - LHFI and ACL, LHFI of this report.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following provides a narrative discussion and analysis of Trustmark Corporation’s (Trustmark) financial condition and results of operations. This discussion should be read in conjunction with the unaudited consolidated financial statements and the supplemental financial data included in Part I. Item 1. – Financial Statements of this report.

Description of Business

Trustmark, a Mississippi business corporation incorporated in 1968, is a bank holding company headquartered in Jackson, Mississippi. Trustmark’s principal subsidiary is Trustmark National Bank (TNB), initially chartered by the State of Mississippi in 1889. At September 30, 2023, TNB had total assets of $18.388 billion, which represented approximately 99.99% of the consolidated assets of Trustmark.

Through TNB and its other subsidiaries, Trustmark operates as a financial services organization providing banking and other financial solutions through offices and 2,756 full-time equivalent associates (measured at September 30, 2023) located in the states of Alabama (includes the Georgia Loan Production Office (LPO), which are collectively referred to herein as Trustmark's Alabama market region), Florida (primarily in the northwest or “Panhandle” region of that state, which is referred to herein as Trustmark’s Florida market), Mississippi, Tennessee (in the Memphis and Northern Mississippi regions, which are collectively referred to herein as Trustmark’s Tennessee market), and Texas (primarily in Houston, which is referred to herein as Trustmark’s Texas market). Trustmark’s operations are managed along three operating segments: General Banking Segment, Wealth Management Segment and Insurance Segment. For a complete overview of Trustmark’s business, see the section captioned “The Corporation” included in Part I. Item 1. – Business of Trustmark’s Annual Report on Form 10-K for its fiscal year ended December 31, 2022 (2022 Annual Report).

Executive Overview

Trustmark's financial results for the three and nine months ended September 30, 2023 reflected solid growth in loans held for investment (LHFI) of $196.3 million, or 1.6%, and $606.2 million, or 5.0%, respectively, as well as growth in deposits of $188.0 million, or 1.3%, and $664.3 million, or 4.6%, respectively, stable net interest income and continued credit quality strength. Trustmark's strong financial performance during the first nine months of 2023 was achieved despite the challenging financial services environment and increasingly competitive deposit costs. On October 9, 2023, Trustmark entered into a settlement agreement that will, pending court approval, resolve all current and potential future claims relating to litigation involving Adams/Madison Timber. As a result, Trustmark recognized $6.5 million of litigation settlement expense which was included in noninterest expense for the third quarter of 2023. Trustmark's capital position remained solid, reflecting the consistent profitability of its diversified financial services businesses.

Trustmark remains well-positioned and committed to meeting the banking and financial needs of its customers and the communities it serves, and remains focused on providing support, advice and solutions to meet its customers’ unique needs. Trustmark is committed to managing the franchise for the long term, supporting investments to promote profitable revenue growth, realigning delivery channels to support changing customer preferences as well as reengineering and efficiency opportunities to enhance long-term shareholder value. Trustmark’s Board of Directors declared a quarterly cash dividend of $0.23 per share. The dividend is payable December 15, 2023, to shareholders of record on December 1, 2023.

Recent Economic and Industry Developments

Economic activity improved slightly during the first nine months of 2023; however, economic concerns remain as a result of the cumulative weight of uncertainty regarding the potential economic impact of geopolitical developments, such as Russia's invasion of Ukraine, inflation, the consequences of recent bank failures and other economic and industry volatility, supply chain issues, higher energy prices and broader price pressures. Doubts surrounding the near-term direction of global markets and the potential impact on the United States economy are expected to persist for the near term. While Trustmark's customer base is wholly domestic, international economic conditions affect domestic economic conditions, and thus may have an impact upon Trustmark's financial condition or results of operations.

Market interest rates began to rise during 2022 after an extended period at historical lows and have continued to rise in 2023. Starting in March 2022, the FRB began raising the target federal funds rate for the first time in three years and continued with multiple increases throughout 2022 and the first nine months of 2023, up to a range of 5.25% to 5.50% as of September 2023. The FRB also signaled the possibility of additional rate increases. In addition, the FRB increased the interest that it pays on reserves multiple times during 2022 and the first nine months of 2023 from 0.10% to 5.40% as of September 2023. As interest rates have increased, so have competitive pressures on the deposit cost of funds. This has been exacerbated by recent bank failures and the resulting heightened competition for deposits, which has also affected the interest that Trustmark pays on deposits. It is not possible to predict the pace and magnitude of changes in interest rates, or the impact rate changes will have on Trustmark's results of operations.

In the October 2023 “Summary of Commentary on Current Economic Conditions by Federal Reserve District,” the twelve Federal Reserve Districts’ reports suggested that during the reporting period (covering the period from August 28, 2023 through October 6, 2023) there was little to no change in economic activity; however, conditions varied across Federal Reserve Districts (Districts). Reports by the twelve Districts noted the following during the reporting period:

•Consumer spending reports were mixed, especially among general retailers and auto dealers, due to differences in prices and product offerings. Tourism activity continued to improved, although some Districts reported a slight slowing in consumer travel and a few Districts reported an increase in business travel. Manufacturing activity was mixed, although contacts across multiple Districts noted an improving outlook for the sector.

•Banking contacts reported slight to modest declines in loan demand. Consumer credit quality was generally described as stable or healthy, with delinquency rates still historically low but slightly increasing. Real estate conditions were little changed and the inventory of homes for sale remained low.

•Overall economic expectations for the coming months was generally described as stable or having slightly weaker growth.

•Labor market tightness continued to ease across the nation. Most Districts reported slight to moderate increases in overall employment and firms hiring less urgently. Several Districts reported improvements in hiring and retention; however, most Districts still reported ongoing challenges in recruiting and hiring skilled tradespeople. Wage growth remained modest to moderate in most Districts. There were multiple reports of firms modifying their compensation packages to mitigate higher labor costs.

•Prices increased at a modest pace overall. Districts noted that input cost increases have slowed or stabilized for manufacturers but continued to rise for services sector firms. Increases in fuel costs, wages and insurance contributed to growth in prices

58

across Districts. Sales prices increased at a slower rate than input prices, as businesses struggled to pass along cost pressures because consumers had grown more sensitive to prices, causing firms to struggle to maintain desired profit margins. Overall, firms expect prices to increase, but at a slower rate, for the next few quarters.

Reports by the Federal Reserve’s Sixth District, Atlanta (which includes Trustmark’s Alabama, Florida and Mississippi market regions), Eighth District, St. Louis (which includes Trustmark’s Tennessee market region), and Eleventh District, Dallas (which includes Trustmark’s Texas market region), noted similar findings for the reporting period as those discussed above. The Federal Reserve’s Sixth District also noted on balance, loan growth slowed across most portfolios, and, while asset quality remained stable, consumers appeared to experience increased financial stress as evidenced by an increase in consumer loan delinquencies. The Federal Reserve's Sixth District reported that financial institutions continued to fund loan growth with large time deposits given heightened competition for core deposits; however, the higher funding cost of time deposits put increased pressure on net interest margins and earnings. The Federal Reserve’s Eighth District also reported that banking conditions remained stable, even as rising deposit interest rates continue to create a tight market for deposits, raising the cost of funds and shrinking profit margins. The Federal Reserve’s Eighth District also noted that demand for consumer loans continued to decline and credit card usage remained elevated, and while banking contacts reported that signs of consumer financial stress are increasing, they believe that overall credit risk remains moderate. The Federal Reserve’s Eighth District also reported that merger and acquisition activity of smaller banks has increased, with investment bankers reaching out for potential buyers. The Federal Reserve’s Eleventh District also reported loan demand and overall loan volumes continued to decline at an accelerated pace during the reporting period, loan nonperformance rose particularly for consumer loans, though increased delinquency was seen across the board, credit standards continued to tighten, loan pricing pushed up further, though at the slowest rate so far this year. The Federal Reserve’s Eleventh District also noted that banking outlooks remain pessimistic, with expectations for increasing loan nonperformance, decreasing loan demand and worsening business activity over the next six months.

The rapid rise in interest rates during 2022 and the first nine months of 2023, the resulting industry-wide reduction in the fair value of securities portfolios and the recent bank runs that led to the failures of some financial institutions in March 2023, among other events, have resulted in a current state of volatility and uncertainty with respect to the health of the United States banking system. There is heightened awareness around liquidity, uninsured deposits, deposit composition, unrecognized investment losses and capital. See further discussion of these items in the remaining sections of the Management’s Discussion and Analysis of this document.

Financial Highlights

Trustmark reported net income of $34.0 million, or basic and diluted earnings per share (EPS) of $0.56, in the third quarter of 2023, compared to $42.5 million, or basic and diluted EPS of $0.69, in the third quarter of 2022. Trustmark’s reported performance during the quarter ended September 30, 2023 produced a return on average tangible equity of 11.32%, a return on average assets of 0.72%, an average equity to average assets ratio of 8.46% and a dividend payout ratio of 41.07%, compared to a return on average tangible equity of 13.90%, a return on average assets of 0.98%, an average equity to average assets ratio of 9.32% and a dividend payout ratio of 33.33% during the quarter ended September 30, 2022.

Trustmark reported net income of $129.4 million, or basic and diluted EPS of $2.12 and $2.11, respectively, for the first nine months of 2023, compared to $106.0 million, or basic and diluted EPS of $1.73 and $1.72, respectively, for the same time period in 2022. Trustmark's reported performance for the nine months ended September 30, 2023 produced a return on average tangible equity of 14.77%, a return on average assets of 0.93%, an average equity to average assets ratio of 8.37% and a dividend payout ratio of 32.55%, compared to a return on average tangible equity of 11.39%, a return on average assets of 0.81%, an average equity to average assets ratio of 9.45% and a dividend payout ratio of 39.88% for the nine months ended September 30, 2022.

Total revenue, which is defined as net interest income plus noninterest income, for the three and nine months ended September 30, 2023 was $190.9 million and $573.3 million, respectively, an increase of $2.2 million, or 1.1%, and $65.2 million, or 12.8%, respectively, when compared to the same time periods in 2022. The increase in total revenue for the three and nine months ended September 30, 2023, when compared to the same time periods in 2022, primarily resulted from an increase in net interest income, principally due to increases in interest and fees on loans held for sale (LHFS) and LHFI and other interest income, largely offset by an increase in total interest expense.

Net interest income for the three and nine months ended September 30, 2023 totaled $138.6 million and $416.1 million, respectively, an increase of $2.5 million, or 1.9%, and $68.0 million, or 19.5%, respectively, when compared to the same time periods in 2022. Interest income totaled $228.5 million and $646.0 million for the three and nine months ended September 30, 2023, respectively, an increase of $84.1 million, or 58.2%, and $280.6 million, or 76.8%, respectively, when compared to the same time periods in 2022, principally due to increases in interest and fees on LHFS and LHFI primarily due to loan growth and rising interest rates and other interest income primarily due to an increase in the rate paid by the Federal Reserve Bank of Atlanta (FRBA) on reserves. Interest expense totaled $89.9 million and $229.8 million for the three and nine months ended September 30, 2023, respectively, an increase of $81.6 million and $212.6 million, respectively, when compared to the same time periods in 2022. The increase in interest expense when

59

the three and nine months ended September 30, 2023 are compared to the same time periods in 2022 was due to an increase in interest on deposits primarily due to rising interest rates, increased competition for deposits and higher average balances, an increase in other interest expense primarily due to the increase in short-term Federal Home Loan Bank (FHLB) advances and an increase in interest on federal funds purchased and securities sold under repurchase agreements primarily due to increases to the target rate for federal funds purchased by the FRB.

Noninterest income for the three months ended September 30, 2023 totaled $52.2 million, a slight decrease of $382 thousand, or 0.7%, when compared to the same time period in 2022, primarily due to declines in bank card and other fees and mortgage banking, net, which were largely offset by an increase in insurance commissions. Bank card and other fees for the three months ended September 30, 2023, totaled $8.2 million, a decrease of $1.1 million, or 11.7%, when compared to the same time period in 2022, principally due to declines in customer derivatives income. Mortgage banking, net totaled $6.5 million for the three months ended September 30, 2023, a decrease of $418 thousand, or 6.1%, when compared to the same time period in 2022, principally due to declines in the gain on sales of loans, net, partially offset by a decline in the run-off of the mortgage servicing rights (MSR) and an increase in mortgage servicing income. Insurance commissions totaled $15.3 million for the third quarter of 2023, an increase of $1.4 million, or 10.0%, when compared to the same time period in 2022, principally due to increases in commercial property and casualty commissions, policy fees and other commission income.

Noninterest income for the first nine months of 2023 totaled $157.2 million, a decrease of $2.8 million, or 1.8%, when compared to the same time period in 2022, principally due to declines in mortgage banking, net and bank card and other fees, partially offset by increases in insurance commissions, service charges on deposit accounts and other income, net. Mortgage banking, net totaled $20.7 million for the first nine months of 2023, a decrease of $4.2 million, or 16.9%, when compared to the first nine months of 2022, principally due to declines in the gain on sales of loans, net and the net hedge ineffectiveness, partially offset by a decline in the run-off of the MSR. Bank card and other fees totaled $24.9 million for the first nine months of 2023, a decline of $3.0 million, or 10.7%, when compared to the same time period in 2022, principally due to a decline in customer derivatives revenue. Insurance commissions totaled $44.4 million for the first nine months of 2023, an increase of $2.7 million, or 6.4%, when compared to the same time period in 2022, principally due to growth in commercial property and casualty commissions. Service charges on deposit accounts totaled $32.1 million for the first nine months of 2023, an increase of $1.1 million, or 3.6%, when compared to the same time period in 2022, principally due to an increase in service charges on personal interest checking accounts. Other income, net totaled $8.6 million for the first nine months of 2023, an increase of $1.1 million, or 14.3%, when compared to the same time period in 2022, principally due to an increase in cash management service charges partially offset by an increase in the amortization of tax credit partnerships.

Noninterest expense for the three and nine months ended September 30, 2023 totaled $140.9 million and $401.5 million, an increase of $14.2 million, or 11.2%, and $29.5 million, or 7.9%, respectively, when compared to the same time periods in 2022. The increase in noninterest expense for the three and nine months ended September 30, 2023 was principally due to increases in salaries and employee benefits, services and fees and other expense as well as the $6.5 million of litigation settlement expense. Excluding the litigation settlement expense, noninterest expense increased $7.7 million, or 6.1%, and $23.0 million, or 6.2%, respectively, when the three and nine months ended September 30, 2023 are compared to the same time periods in 2022. Salaries and employee benefits totaled $76.7 million and $226.7 million for the three and nine months ended September 30, 2023, respectively, an increase of $4.0 million, or 5.4%, and $12.7 million, or 5.9%, respectively, when compared to the same time periods in 2022, principally due to increases in salaries expense, primarily due to general merit increases, accrued management performance incentives and commission expense due to improvements in insurance production, partially offset by a decline in commission expense due to the decline in mortgage originations. Services and fees totaled $27.9 million and $81.6 million for the three and nine months ended September 30, 2023, respectively, an increase of $1.1 million, or 4.1%, and $3.8 million, or 4.9%, respectively, when compared to the same time periods in 2022, principally due to increases in data processing charges related to software, business processing outsourcing fees and advertising expense, partially offset by an decrease in other services and fees. Other expense totaled $15.7 million and $45.0 million for the three and nine months ended September 30, 2023, respectively, an increase of $2.0 million, or 14.3%, and $4.3 million, or 10.6%, respectively, when compared to the same time period in 2022, principally due to increases in FDIC assessment expense, primarily due to an increase in the assessment rate, and other miscellaneous expenses.

Trustmark’s provision for credit losses (PCL) on LHFI for the three and nine months ended September 30, 2023 totaled $8.3 million and $19.8 million, respectively, a decrease of $4.6 million, or 35.6%, and an increase of $5.0 million, or 33.9%, respectively, when compared to the same time periods in 2022. The PCL on LHFI for the three and nine months ended September 30, 2023 primarily reflected an increase in required reserves as a result of loan growth, weakening in the macroeconomic forecasts and the net impact of qualitative changes including adjustments to the credit quality trend reserve, the commercial real estate concentration reserve and the nature and volume of the portfolio, partially offset by a decline in specific reserves for individually analyzed LHFI. The PCL on off-balance sheet credit exposures totaled $104 thousand and a negative $1.9 million for the three and nine months ended September 30, 2023, respectively, an increase in provision expense of $1.4 million and $2.1 million, respectively, when compared to the same time periods in 2022. The PCL on off-balance sheet credit exposures for the three months ended September 30, 2023, primarily reflected an increase in required reserves as a result of changes in the total reserve rate, which was largely offset by a decrease in required reserves

60

due to a decline in unfunded commitments. The release in PCL on off-balance sheet credit exposures for the nine months ended September 30, 2023, primarily reflected a decrease in required reserves due to a decline in unfunded commitments. Please see the section captioned “Provision for Credit Losses” for additional information regarding the PCL on LHFI and off-balance sheet credit exposures.

At September 30, 2023, nonperforming assets totaled $96.4 million, an increase of $28.4 million, or 41.8%, compared to December 31, 2022, primarily as a result of an increase in nonaccrual LHFI. Nonaccrual LHFI totaled $90.9 million at September 30, 2023, an increase of $24.9 million, or 37.8%, relative to December 31, 2022, primarily as a result of two large commercial credits placed on nonaccrual that were partially offset by other commercial credits that were foreclosed, charged-off, returned to accrual or paid off.

LHFI totaled $12.810 billion at September 30, 2023, an increase of $606.2 million, or 5.0%, compared to December 31, 2022. The increase in LHFI during the first nine months of 2023 was primarily due to net growth in LHFI secured by real estate partially offset by a decline in state and other political subdivision LHFI. For additional information regarding changes in LHFI and comparative balances by loan category, see the section captioned “LHFI.”

Management has continued its practice of maintaining excess funding capacity to provide Trustmark with adequate liquidity for its ongoing operations. In this regard, Trustmark benefits from its strong deposit base, its investment portfolio and its access to funding from a variety of external funding sources such as upstream federal funds lines, FHLB advances and brokered deposits. See the section captioned “Capital Resources and Liquidity” for further discussion of the components of Trustmark’s excess funding capacity.

Total deposits were $15.102 billion at September 30, 2023, an increase of $664.3 million, or 4.6%, compared to December 31, 2022. During the first nine months of 2023, noninterest-bearing deposits decreased $773.6 million, or 18.9%, as a result of declines in all categories of noninterest-bearing deposits reflecting customers' desire for higher-yielding deposit accounts. Interest-bearing deposits increased $1.438 billion, or 13.9%, during the first nine months of 2023, primarily due to growth in certificates of deposits (CDs), which was principally attributable to deposit campaigns offered during the first nine months of 2023 and the addition of $727.3 million of brokered CDs, business and consumer money market deposit accounts (MMDA) and business interest checking accounts, partially offset by declines in public and consumer interest checking accounts and consumer savings accounts.

Federal funds purchased and securities sold under repurchase agreements totaled $321.8 million at September 30, 2023, a decrease of $127.5 million, or 28.4%, compared to December 31, 2022, principally due to a decrease in upstream federal funds purchased. Other borrowings totaled $793.2 million at September 30, 2023, a decrease of $257.7 million, or 24.5%, compared to December 31, 2022, principally due to a decline in short-term FHLB advances obtained from the FHLB of Dallas.

Recent Legislative and Regulatory Developments

Community Reinvestment Act Reform

On October 24, 2023, the Office of the Comptroller of the Currency, the FRB and the FDIC (the Agencies) released a final rule significantly revising the framework that the Agencies use to evaluate banks’ records of meeting the credit needs of their entire communities under the Community Reinvestment Act (CRA). Under the revised framework, banks with assets of at least $2 billion, including TNB, are considered large banks and, accordingly, will have their retail lending, retail services and products, community development financing and community development services subject to periodic evaluation under complex, multi-part standards. Large banks will be subject to enhanced data collection and reporting requirements, with additional data collection and reporting requirements applying to banks, including Trustmark, with assets greater than $10 billion. Depending on a large bank’s geographic concentrations of lending, the evaluation of retail lending may include assessment areas in which the bank extends loans but does not operate any deposit-taking facilities, in addition to assessment areas in which the bank has deposit-taking facilities. The rule becomes effective April 1, 2024. Compliance with most provisions of the final rule will be required beginning January 1, 2026, and compliance with the remaining provisions will be required beginning January 1, 2027. Trustmark is evaluating the impact of the final rule.

FDIC Special Assessment

On May 11, 2023, the FDIC issued a proposed rule if adopted would impose special assessments to recover the loss to the FDIC’s Deposit Insurance Fund (DIF) incurred in the receiverships of these institutions. Under the proposed rule, the FDIC would collect special assessments at an annual rate of approximately 12.5 basis points, over eight quarterly assessment periods. The assessment base for the special assessments under the proposed rule would be equal to an insured depository institution's estimated uninsured deposits, reported as of December 31, 2022, adjusted to exclude the first $5 billion in estimated uninsured deposits. Under the proposed rule, the FDIC would retain the ability to cease collection early, extend the special assessment collection period one or more quarters beyond the initial eight-quarter collection period to collect the difference between estimated or actual losses and the amounts collected, and impose

61

a final shortfall special assessment on a one-time basis after the receiverships for Silicon Valley Bank and Signature Bank terminate. The special assessments as proposed are not expected to be material to Trustmark's financial condition or results of operations.

Small Business Lending Data Collection Rule

On March 30, 2023, the CFPB finalized a rule under section 1071 of the Dodd-Frank Act requiring lenders to collect and report data regarding small business lending activity. Trustmark is evaluating the impact of the new rule. The rule was scheduled to take effect on August 29, 2023, and requires compliance by October 1, 2024, April 1, 2025, or January 1, 2026, depending on the number of covered small business loans that a covered lender originates. On July 31 2023, the U.S. District Court for the Southern District of Texas enjoined the CFPB from implementing and enforcing the rule with respect to American Bankers Association members, which includes Trustmark, pending the U.S. Supreme Court's consideration of the constitutionality of the CFPB's funding structure in a separate case. On October 26, 2023, the court expanded the scope of its injunction to cover banks nationwide.

Non-GAAP Financial Measures

In addition to capital ratios defined by U.S. generally accepted accounting principles (GAAP) and banking regulators, Trustmark utilizes various tangible common equity measures when evaluating capital utilization and adequacy. Tangible common equity, as defined by Trustmark, represents common equity less goodwill and identifiable intangible assets. Trustmark's common equity Tier 1 capital includes common stock, capital surplus and retained earnings, and is reduced by goodwill and other intangible assets, net of associated net deferred tax liabilities as well as disallowed deferred tax assets and threshold deductions as applicable.

Trustmark believes these measures are important because they reflect the level of capital available to withstand unexpected market conditions. Additionally, presentation of these measures allows readers to compare certain aspects of Trustmark’s capitalization to other organizations. These ratios differ from capital measures defined by banking regulators principally in that the numerator excludes shareholders’ equity associated with preferred securities, the nature and extent of which varies across organizations. In Management’s experience, many stock analysts use tangible common equity measures in conjunction with more traditional bank capital ratios to compare capital adequacy of banking organizations with significant amounts of goodwill or other intangible assets, typically stemming from the use of the purchase accounting method in accounting for mergers and acquisitions.

These calculations are intended to complement the capital ratios defined by GAAP and banking regulators. Because GAAP does not include these capital ratio measures, Trustmark believes there are no comparable GAAP financial measures to these tangible common equity ratios. Despite the importance of these measures to Trustmark, there are no standardized definitions for them and, as a result, Trustmark’s calculation methods may not be comparable with those of other organizations. Also, there may be limits in the usefulness of these measures to investors. As a result, Trustmark encourages readers to consider its consolidated financial statements and the notes related thereto in their entirety and not to rely on any single financial measure.

Trustmark discloses certain non-GAAP financial measures, including net income adjusted for significant non-routine transactions, because Management uses these measures for business planning purposes, including to manage Trustmark’s business against internal projected results of operations and to measure Trustmark’s performance. Trustmark views these as measures of its core operating business, which exclude the impact of the items detailed below, as these items are generally not operational in nature. These non-GAAP financial measures also provide another basis for comparing period-to-period results as presented in the accompanying selected financial data table and the consolidated financial statements by excluding potential differences caused by non-operational and unusual or non-recurring items. Readers are cautioned that these adjustments are not permitted under GAAP. Trustmark encourages readers to consider its consolidated financial statements and the notes related thereto in their entirety, and not to rely on any single financial measure.

Net Interest Income

Net interest income is the principal component of Trustmark’s income stream and represents the difference, or spread, between interest and fee income generated from earning assets and the interest expense paid on deposits and borrowed funds. Fluctuations in interest rates, as well as volume and mix changes in earning assets and interest-bearing liabilities, can materially impact net interest income. The net interest margin is computed by dividing fully taxable equivalent (FTE) net interest income by average interest-earning assets and measures how effectively Trustmark utilizes its interest-earning assets in relationship to the interest cost of funding them. The accompanying yield/rate analysis tables show the average balances for all assets and liabilities of Trustmark and the interest income or expense associated with earning assets and interest-bearing liabilities. The yields and rates have been computed based upon interest income and expense adjusted to a FTE basis using the federal statutory corporate tax rate in effect for each of the periods shown. Loans on nonaccrual have been included in the average loan balances, and interest collected prior to these loans having been placed on nonaccrual has been included in interest income. Loan fees included in interest associated with the average LHFS and LHFI balances were immaterial.

Net interest income-FTE for the three and nine months ended September 30, 2023 increased $2.9 million, or 2.1%, and $69.3 million, or 19.4%, respectively, when compared with the same time periods in 2022. The increase in net interest income-FTE when the three and nine months ended September 30, 2023 are compared to the same time periods in 2022 was principally due to increases in interest and fees on LHFS and LHFI-FTE and other interest income, partially offset by increases in all categories of interest expense. The net interest margin-FTE for the three and nine months ended September 30, 2023 decreased 21 basis points to 3.29% and increased 34 basis points to 3.34%, respectively, when compared to the same time periods in 2022. The net interest margin excluding PPP loans and the balance held at the FRBA, which equals the reported net interest income-FTE excluding interest and fees on PPP and interest on the FRBA balance, as a percentage of average earning assets excluding average PPP loans and the FRBA balance, was 3.24% and 3.27% for the three and nine months ended September 30, 2023, respectively, a decrease of 29 basis points and an increase of 10 basis points, respectively, when compared to the same time periods in 2022. The decrease in the net interest margin excluding PPP loans and the balance held at the FRBA for the three months ended September 30, 2023 when compared to the same time period in 2022, was principally due to increases in the costs of interest-bearing liabilities partially offset by the increase in the yield on the LHFS and LHFI portfolios. The increase in the net interest margin excluding PPP loans and the balance held at the FRBA for the nine months ended September 30, 2023 compared to the same time period in 2022, was principally due to the increase in the yield on the LHFS and LHFI portfolio partially offset by increases in the costs of interest-bearing liabilities.

At September 30, 2023, Trustmark had no PPP loans outstanding compared to $4.8 million, net of $95 thousand of deferred fees and costs, outstanding at September 30, 2022. Processing fees earned by TNB as the originating lender were amortized over the life of the loans. Payments on PPP loans were deferred until the date the SBA remitted the borrower’s loan forgiveness amount to the lender (or, if the borrower did not apply for loan forgiveness, ten months after the end of the borrower’s loan forgiveness covered period). During the first nine months of 2022, PPP loans originated by Trustmark totaling $28.9 million were forgiven by the SBA. Average PPP loans

66

for the three and nine months ended September 30, 2022 totaled $9.8 million and $18.8 million, respectively. Interest and fees on PPP loans for the three and nine months ended September 30, 2022 totaled $186 thousand and $538 thousand, respectively, resulting in yield on PPP loans of 7.51% and 3.83%, respectively.

The average FRBA balance, included in other earning assets, for the three and nine months ended September 30, 2023 totaled $566.3 million and $633.0 million, respectively, an increase of $290.9 million and a decrease of $398.5 million, respectively, when compared to the same time periods in 2022. The increase in the average FRBA balance when the three months ended September 30, 2023 is compared to the same time period in 2022, was principally due to Management's decision to manage the FRBA to a higher balance to increase on hand liquidity during the period. The decrease in the average FRBA balance when the nine months ended September 30, 2023 is compared to the same time period in 2022, was principally due to the deployment of excess cash and the significant growth in the LHFI portfolio during 2022. Interest earned on FRBA balances increased $5.7 million and $19.6 million, respectively, when the three and nine months ended September 30, 2023 are compared to the same time periods in 2022. The yield on the FRBA balance was 4.92% and 4.97% for the three and nine months ended September 30, 2023, respectively, compared to 1.86% and 0.51% for the same time periods in 2022, respectively, reflecting increases in the interest rate that the FRBA pays on reserves.

Average interest-earning assets for the three and nine months ended September 30, 2023 were $17.110 billion and $17.076 billion, respectively, compared to $15.770 billion and $15.937 billion for the same time periods in 2022, respectively, an increase of $1.340 billion, or 8.5%, and $1.139 billion, or 7.1%, respectively. The increase in average interest-earning assets for the three months ended September 30, 2023 when compared to the same time period in 2022, was principally due to increases in average loans (LHFS and LHFI) and average other earning assets, partially offset by a decline in average total securities. The increase in average earning assets for the nine months ended September 30, 2023 when compared to the same time period in 2022, was principally due to increases in average loans (LHFS and LHFI), partially offset by declines in average other earning assets and average securities. Average loans (LHFS and LHFI) increased $1.467 billion, or 12.8%, and $1.754 billion, or 16.0%, when the three and nine months ended September 30, 2023 are compared to the same time period in 2022, respectively, principally due to an increase in the average balance of the LHFI portfolio of $1.274 billion, or 11.9%, and $1.702 billion, or 15.8%, respectively. The increase in the LHFI portfolio when the balances at September 30, 2023 are compared to September 30, 2022 was principally due to net growth in LHFI secured by real estate and commercial and industrial LHFI, partially offset by a decrease in state and other political subdivision LHFI. Average other earning assets increased $357.0 million when the three months ended September 30, 2023 is compared to the same time period in 2022, primarily due to an increase in reserves held at the FRBA. Average other earning assets decreased $339.1 million, or 31.2%, when the nine months ended September 30, 2023 is compared to the same time period in 2022, respectively, primarily due to the decrease in reserves held at the FRBA. Average total securities declined $474.3 million, or 11.9%, and $259.8 million, or 6.7%, when the three and nine months ended September 30, 2023 are compared to the same time periods in 2022, respectively, principally due to calls, maturities and pay-downs of the loans underlying GSE guaranteed securities.

Interest income-FTE for the three and nine months ended September 30, 2023 totaled $231.8 million and $656.1 million, respectively, an increase of $84.4 million, or 57.3%, and $281.9 million, or 75.3%, respectively, while the yield on total earning assets increased to 5.38% and 5.14%, respectively, compared to 3.71% and 3.14% for the same time periods in 2022, respectively. Interest income-FTE, excluding PPP loans and the balance held at the FRBA, for the three and nine months ended September 30, 2023 increased $78.9 million, or 54.1%, and $262.8 million, or 71.1%, respectively, while the yield on total earning assets excluding PPP loans and the balance held at the FRBA increased to 5.39% and 5.14%, respectively, compared 3.74% and 3.32% for the same time periods in 2022, respectively. The increase in interest income-FTE, excluding PPP loans and the balance held at the FRBA, for the three and nine months ended September 30, 2023 was primarily due to increases in interest and fees on LHFS and LHFI-FTE. During the three and nine months ended September 30, 2023, interest and fees on LHFS and LHFI-FTE increased $77.1 million, or 59.6%, and $252.8 million, or 77.6%, respectively, while the yield on LHFS and LHFI increased 186 basis points to 6.34% and 210 basis points to 6.07%, respectively, when compared to the same time periods in 2022, primarily due to the higher interest rate environment as well as the increase in the average balance of LHFI.

Average interest-bearing liabilities for the three and nine months ended September 30, 2023 totaled $13.105 billion and $12.914 billion, respectively, compared to $10.763 billion and $10.808 billion for the same time periods in 2022, respectively, an increase of $2.342 billion, or 21.8%, and $2.106 billion, or 19.5%, respectively. The increase in average interest-bearing liabilities when the three and nine months ended September 30, 2023 are compared to the same time periods in 2022 was primarily the result of the increases in average interest-bearing deposits, average other borrowings and average federal funds purchased and securities sold under repurchase agreements. Average interest-bearing deposits for the three and nine months ended September 30, 2023 increased $1.353 billion, or 13.2%, and $855.9 million, or 8.3%, respectively, when compared to the same time periods in 2022, reflecting growth in average time deposits and average interest-bearing demand deposits, partially offset by declines in savings deposits. Average other borrowings for the three and nine months ended September 30, 2023 increased $823.7 million and $1.030 billion, respectively, when compared to the same time periods in 2022, principally due to the increase in outstanding short-term FHLB advances with the FHLB of Dallas as a result of changes in funding needs to support the strong loan growth. Average federal funds purchased and securities sold under repurchase

67

agreements for the three and nine months ended September 30, 2023 increased $164.9 million and $219.9 million, respectively, when compared to the same time periods in 2022, principally due to an increase in upstream federal funds purchased.

Interest expense for the three and nine months ended September 30, 2023 totaled $89.9 million and $229.8 million, respectively, an increase of $81.6 million and $212.6 million, respectively, when compared with the same time periods in 2022, while the rate on total interest-bearing liabilities increased 241 basis points to 2.72% and 217 basis points to 2.38%, respectively, reflecting increases in all categories of interest expense. Interest on deposits for the three and nine months ended September 30, 2023 increased $64.7 million and $154.5 million, respectively, while the rate on interest-bearing deposits increased 219 basis points to 2.39% and 183 basis points to 1.97%, respectively, when compared to the same time periods in 2022, primarily due to higher interest rates, reflecting the increased competitive pressures on deposits, and increases in average balances of time deposits and business interest checking accounts. Other interest expense for the three and nine months ended September 30, 2023 increased $12.7 million and $44.4 million, respectively, while the rate on other borrowings increased to 5.32% and 5.10%, respectively, compared to 2.89% and 2.56% for the same time periods in 2022, respectively, primarily due to the increase in outstanding short-term FHLB advances with the FHLB of Dallas. Interest on federal funds purchased and securities sold under repurchase agreements for the three and nine months ended September 30, 2023 increased $4.2 million and $13.7 million, respectively, while the rate on federal funds purchased and securities sold under repurchase agreements increased to 5.14% and 4.87%, respectively, when compared to 1.95% and 0.94% for the same time periods in 2022, respectively, reflecting the FRB's increases to the target rate for federal funds purchased as well as the increase in average upstream federal funds purchased.

Provision for Credit Losses

The PCL, LHFI is the amount necessary to maintain the ACL for LHFI at the amount of expected credit losses inherent within the LHFI portfolio. The amount of PCL and the related ACL for LHFI are based on Trustmark’s ACL methodology. The PCL, LHFI totaled $8.3 million and $19.8 million for the three and nine months ended September 30, 2023, respectively, compared to $12.9 million and $14.8 million, respectively, for the same time periods in 2022. The PCL on LHFI for the three and nine months ended September 30, 2023 primarily reflected an increase in required reserves as a result of loan growth, weakening in the macroeconomic forecasts and the net impact of qualitative changes including adjustments to the credit quality trend reserve, the commercial real estate concentration reserve and the nature and volume of the portfolio, partially offset by a decline in specific reserves for individually analyzed LHFI.

FASB ASC Topic 326 requires Trustmark to estimate expected credit losses for off-balance sheet credit exposures which are not unconditionally cancellable by Trustmark. Trustmark maintains a separate ACL for off-balance sheet credit exposures, including unfunded commitments and letters of credit. Adjustments to the ACL on off-balance sheet credit exposures are recorded to the PCL, off-balance sheet credit exposures. The PCL, off-balance sheet credit exposures totaled $104 thousand and a negative $1.9 million for the three and nine months ended September 30, 2023, respectively, compared to a negative $1.3 million and a negative $4.0 million, respectively, for the same time periods in 2022. The PCL on off-balance sheet credit exposures for the three months ended September 30, 2023, primarily reflected an increase in required reserves as a result of changes in the total reserve rate, which was largely offset by a decrease in required reserves due to a decline in unfunded commitments. The release in PCL on off-balance sheet credit exposures

for the nine months ended September 30, 2023, primarily reflected a decrease in required reserves due to a decline in unfunded commitments.

See the section captioned “Allowance for Credit Losses” for information regarding Trustmark’s ACL methodology as well as further analysis of the PCL.

Noninterest Income

Noninterest income represented 27.4% of total revenue for both the three and nine months ended September 30, 2023, respectively, compared to 27.9% and 31.5% or the three and nine months ended September 30, 2022, respectively. The following table provides the comparative components of noninterest income for the periods presented ($ in thousands):

	Three Months Ended September 30,										Nine Months Ended September 30,

Changes in various components of noninterest income are discussed in further detail below. For analysis of Trustmark’s insurance commissions and wealth management income, please see the section captioned “Results of Segment Operations.”

Service Charges on Deposit Accounts

The increase in service charges on deposit accounts when the first nine months of 2023 is compared to the same time period in 2022 was principally due to an increase in service charges on personal interest checking accounts.

Bank Card and Other Fees

The decrease in bank card and other fees when the three and nine months ended September 30, 2023 is compared to the same time period in 2022 was principally due to declines in customer derivatives income.

The decrease in mortgage banking, net for the three months ended September 30, 2023 when compared to the same time period in 2022 was principally due to decline in the gain on sales of loans, net, partially offset by a decline in the run-off of the MSR and an increase in mortgage servicing income. The decrease in mortgage banking, net when the first nine months of 2023 is compared to the same time period in 2022 was principally due to declines in the gain on sales of loans, net and the net hedge ineffectiveness, partially offset by a decline in the run-off of the MSR. Mortgage loan production for the three and nine months ended September 30, 2023 was $389.9 million and $1.182 billion, respectively, a decrease of $118.4 million, or 23.3%, and $551.8 million, or 31.8%, respectively, when compared to the same time periods in 2022. Loans serviced for others totaled $8.403 billion at September 30, 2023, compared with $8.078 billion at September 30, 2022, an increase of $325.7 million, or 4.0%.

Representing a significant component of mortgage banking income is the gain on sales of loans, net. The decrease in the gain on sales of loans, net when the three months ended September 30, 2023 is compared to the same time period in 2022, was primarily the result of lower profit margins in secondary marketing activities partially offset by increases in the mortgage fair value adjustment and the volume of loans sold. The decrease in the gain on sales of loans, net when the nine months ended September 30, 2023 is compared to the same time period in 2022, was primarily the result of lower profit margins in secondary marketing activities and a decline in the volume of loans sold, partially offset by an increase in the mortgage fair value adjustment. Loan sales totaled $343.7 million and $893.0 million for the three and nine months ended September 30, 2023, respectively, an increase of $28.5 million, or 9.0%, and a decreased if $133.3 million, or 13.0%, respectively, when compared with the same time periods in 2022.

Other Income, Net

The following table illustrates the components of other income, net included in noninterest income for the periods presented ($ in thousands):

The increase in other income, net for the first nine months of 2023, when compared to the same time period in 2022 was principally due to an increase in cash management service charges partially offset by an increase in the amortization of tax credit partnerships.

Noninterest Expense

(1)During the first quarter of 2023, Trustmark reclassified its debit card transaction fees from other expense to services and fees. The prior periods have been reclassified accordingly.

Changes in the various components of noninterest expense are discussed in further detail below. Management considers disciplined expense management a key area of focus in the support of improving shareholder value.

Salaries and Employee Benefits

The increase in salaries and employee benefits when the three and nine months ended September 30, 2023 is compared to the same time periods in 2022 was principally due to increases in salaries expense, primarily due to general merit increases, accrued management

72

performance incentives and commission expense due to improvements in insurance production, partially offset by a decline in commission expense due to the decline in mortgage originations.

Services and Fees

The increase in services and fees for the three and nine months ended September 30, 2023 was principally due to increases in data processing charges related to software, business processing outsourcing fees and advertising expense, partially offset by a decrease in other services and fees.

Other Expense

The following table illustrates the comparative components of other noninterest expense for the periods presented ($ in thousands):

	Three Months Ended September 30,											Nine Months Ended September 30,
	2023			2022		$ Change			% Change			2023		2022		$ Change			% Change

(1)During the first quarter of 2023, Trustmark reclassified its debit card transaction fees from other expense to services and fees. The prior periods have been reclassified accordingly.

The increase in other expense when the three and nine months ended September 30, 2023 are compared to the same time periods in 2022 was principally due to increases in FDIC assessment expense and other miscellaneous expenses. The increase in FDIC assessment expense when the three and nine months ended September 30, 2023 are compared to the same time periods in 2022 was principally due to changes in the assessment rate calculation, deployment of Trustmark's excess cash balance during 2022, which increased the overall assessment rate, and the 2 basis point increase in the initial base assessment rate by the FDIC during the second quarter of 2023 as part of the FDIC's final rule to restore the DIF to required levels. The increase in other miscellaneous expenses when the three and nine months ended September 30, 2023 are compared to the same time periods in 2022 was principally due to increases in travel and entertainment expense and other various miscellaneous expenses.

Results of Segment Operations

For a description of the methodologies used to measure financial performance and financial information by reportable segment, please see Note 18 – Segment Information included in Part I. Item 1. – Financial Statements of this report. The following discusses changes in the results of operations of each reportable segment for the nine months ended September 30, 2023 and 2022.

General Banking

Net interest income for the General Banking Segment increased $67.5 million, or 19.6%, when the nine months ended September 30, 2023 is compared with the same time period in 2022. The increase in net interest income was principally due to increases in interest and fees on LHFS and LHFI and other interest income, partially offset by increases in all categories of interest expense. The PCL (LHFI and off-balance sheet credit exposures) for the General Banking Segment for the nine months ended September 30, 2023 totaled $20.0 million compared to a PCL of $10.8 million for the same period in 2022, an increase of $9.2 million, or 85.6%. For more information on these net interest income and PCL items, please see the sections captioned “Financial Highlights” and “Results of Operations.”

Noninterest income for the General Banking Segment decreased $5.6 million, or 6.2%, when the first nine months of 2023 is compared to the same time period in 2022, primarily due to the declines in mortgage banking, net and bank card and other fees partially offset by an increase in service charges on deposit accounts. Noninterest income for the General Banking Segment represented 17.2% of total revenue for this segment for the first nine months of 2023 compared to 20.9% for the same time period in 2022. Noninterest income for the General Banking Segment includes service charges on deposit accounts; bank card and other fees; mortgage banking, net and other income, net. For more information on these noninterest income items, please see the analysis included in the section captioned “Noninterest Income.”

73

Noninterest expense for the General Banking Segment increased $26.9 million, or 8.4%, when the first nine months of 2023 is compared with the same time period in 2022, principally due to increases in salaries and employee benefits, data processing charges related to software, FDIC assessment expense and the $6.5 million of litigation settlement expense, partially offset by declines in loan expenses and other services and fees. Excluding the litigation settlement expense, noninterest expense increased $20.4 million, or 6.4%, when the first nine months of 2023 is compared to the same time period in 2022. For more information on these noninterest expense items, please see the analysis included in the section captioned “Noninterest Expense.”

Wealth Management

Net income for the Wealth Management Segment for the first nine months of 2023 increased $1.6 million, or 34.0%, when compared to the same time period in 2022, primarily due to an increase in the negative PCL, partially offset by a decrease in noninterest income. Net interest income for the Wealth Management Segment increased $514 thousand, or 13.0%, when the first nine months of 2023 is compared to the same time period in 2022, principally due to an increase in interest and fees on loans generated by the Private Banking Department partially offset by an increase in interest expense on deposits. The PCL for the nine months ended September 30, 2023 totaled a negative $2.1 million compared to a negative PCL of $10 thousand for the same period in 2022. Noninterest income for the Wealth Management Segment, which primarily includes income related to investment management, trust and brokerage services, decreased $812 thousand, or 3.0%, when the first nine months of 2023 is compared to the same time period in 2022, primarily due to a decline in income from brokerage services partially offset by an increase in income from trust management services. Noninterest expense for the Wealth Management Segment decreased $361 thousand, or 1.5%, when the first nine months of 2023 is compared to the same time period in 2022, principally due to a decrease in salaries and employee benefits expense, primarily related to broker commissions and trust incentives.

At September 30, 2023 and 2022, Trustmark held assets under management and administration of $8.235 billion and $16.528 billion, respectively, and brokerage assets of $2.431 billion and $2.172 billion, respectively.

Insurance

Net income for the Insurance Segment for the first nine months of 2023 increased $501 thousand, or 5.2%, when compared to the same time period in 2022. Noninterest income for the Insurance Segment, which is predominately composed of insurance commissions, increased $3.6 million, or 8.7%, when the first nine months of 2023 is compared to the same time period in 2022, primarily due to new business commission volume in the commercial property and casualty business. Noninterest expense for the Insurance Segment increased $3.0 million, or 10.2%, when the first nine months of 2023 is compared to the same time period in 2022, primarily due to increases in salary expense as a result of general merit increases and commission expense as a result of higher business volumes.

Income Taxes

For the three and nine months ended September 30, 2023, Trustmark’s combined effective tax rate was 18.0% and 16.0%, respectively, compared to 15.8% and 15.5%, respectively, for the same time periods in 2022. Trustmark’s effective tax rate continues to be less than the statutory rate primarily due to various tax-exempt income items and its utilization of income tax credit programs. Trustmark invests in partnerships that provide income tax credits on a Federal and/or State basis (i.e., new market tax credits, low-income housing tax credits or historical tax credits). The income tax credits related to these partnerships are utilized as specifically allowed by income tax law and are recorded as a reduction in income tax expense.

Financial Condition

Earning assets serve as the primary revenue streams for Trustmark and are comprised of securities, loans, federal funds sold, securities sold under reverse repurchase agreements and other earning assets. Average earning assets totaled $17.076 billion, or 91.5% of total average assets, for the nine months ended September 30, 2023, compared to $15.937 billion, or 91.7% of total average assets, for the nine months ended September 30, 2022, an increase of $1.139 billion, or 7.1%.

Securities

The securities portfolio is utilized by Management to manage interest rate risk, generate interest income, provide liquidity and use as collateral for public deposits and wholesale funding. Risk and return can be adjusted by altering duration, composition and/or balance of the portfolio. The weighted-average life of the portfolio was 4.7 years at September 30, 2023 compared to 4.9 years at December 31, 2022.

74

When compared to December 31, 2022, total investment securities decreased by $314.1 million, or 8.9%, during the first nine months of 2023. This decrease resulted primarily from calls, maturities and pay-downs of the loans underlying GSE guaranteed securities. Trustmark sold no securities during the first nine months of 2023 or 2022.

During 2022, Trustmark reclassified approximately $766.0 million of securities available for sale to securities held to maturity to mitigate the potential adverse impact of a rising interest rate environment on the fair value of the available for sale securities and the related impact on tangible common equity. At 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 resulting net unrealized holding losses are being 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.

At September 30, 2023, the net unamortized, unrealized loss on all transferred securities included in accumulated other comprehensive income (loss), net of tax, (AOCI) in the accompanying consolidated balance sheets totaled $60.4 million, net of tax, compared to $69.2 million, net of tax, at December 31, 2022.

Available for sale securities are carried at their estimated fair value with unrealized gains or losses recognized, net of taxes, in AOCI, a separate component of shareholders’ equity. At September 30, 2023, available for sale securities totaled $1.766 billion, which represented 55.1% of the securities portfolio, compared to $2.024 billion, or 57.5% of total securities, at December 31, 2022. At September 30, 2023, unrealized losses, net on available for sale securities totaled $262.7 million compared to unrealized losses, net of $246.6 million at December 31, 2022. At September 30, 2023, available for sale securities consisted of U.S. Treasury securities, obligations of states and political subdivisions, GSE guaranteed mortgage-related securities and direct obligations of government agencies and GSEs.

Held to maturity securities are carried at amortized cost and represent those securities that Trustmark both intends and has the ability to hold to maturity. At September 30, 2023, held to maturity securities totaled $1.438 billion, which represented 44.9% of the total securities portfolio, compared to $1.495 billion, or 42.5% of total securities, at December 31, 2022.

Management continues to focus on asset quality as one of the strategic goals of the securities portfolio, which is evidenced by the investment of 99.9% of the portfolio in GSE-backed obligations and other Aaa-rated securities as determined by Moody’s Investors Services (Moody’s). None of the securities owned by Trustmark are collateralized by assets which are considered sub-prime. Furthermore, outside of stock ownership in the FHLB of Dallas, FHLB of Atlanta and FRBA, Trustmark does not hold any other equity investment in a GSE or other governmental entity.

As of September 30, 2023, Trustmark did not hold securities of any one issuer with a carrying value exceeding 10% of total shareholders’ equity, other than certain GSEs which are exempt from inclusion. Management continues to closely monitor the credit quality as well as the ratings of the debt and mortgage-backed securities issued by the GSEs and held in Trustmark’s securities portfolio.

The following table presents Trustmark’s securities portfolio by amortized cost and estimated fair value and by credit rating, as determined by Moody’s, at September 30, 2023 and December 31, 2022 ($ in thousands):

LHFI	$	12,810,259		100.0	%	$	12,204,039		100.0	%

LHFI increased $606.2 million, or 5.0%, compared to December 31, 2022. The increase in LHFI during the first nine months of 2023 was primarily due to net growth in LHFI secured by real estate partially offset by a decline in state and other political subdivision LHFI.

76

LHFI secured by real estate increased $774.3 million, or 9.1%, during the first nine months of 2023, primarily due to net growth in LHFI secured by other real estate, LHFI secured by nonfarm, nonresidential properties (NFNR) and LHFI secured by 1-4 family residential properties, partially offset by a decline in other construction LHFI and construction, land development and other land LHFI. LHFI secured by other real estate increased $476.0 million, or 64.1%, during the first nine months of 2023, primarily due to other construction loans that moved to LHFI secured by multi-family residential properties in the Alabama, Texas and Mississippi market regions. Excluding other construction loan reclassifications, LHFI secured by other real estate decreased $52.2 million, or 7.0%, during the first nine months of 2023 principally due to declines in LHFI secured by multi-family residential properties in the Mississippi and Alabama market regions, partially offset by growth in LHFI secured by multi-family LHFI in the Texas market region. NFNR LHFI increased $290.8 million, or 8.9%, during the first nine months of 2023 principally due to other construction loans that moved to NFNR LHFI in all five market regions. Excluding other construction loan reclassifications, NFNR LHFI decreased $152.2 million, or 4.6%, during the first nine months of 2023 due to declines in nonowner-occupied loans across all market regions with the exception of Texas as well as owner-occupied loans in all market regions with the exception of Mississippi. LHFI secured by 1-4 family residential properties increased $104.7 million, or 4.8%, during the first nine months of 2023 primarily reflecting new mortgage loan production. Other construction loans decreased $75.0 million, or 7.3%, during the first nine months of 2023 primarily due to new construction loans in the Alabama, Texas, Mississippi and Florida market regions partially offset by other construction loans moved to other loan categories upon the completion of the related construction project. During the first nine months of 2023, $971.2 million loans were moved from other construction to other loan categories, including $528.2 million to multi-family residential loans, $383.2 million to nonowner-occupied loans and $59.8 million to owner-occupied loans. Excluding all reclassifications between loan categories, growth in other construction loans totaled $892.6 million, or 86.8%, during the first nine months of 2023. LHFI secured by construction, land development and other land decreased $35.2 million, or 5.1%, during the first nine months of 2023 primarily due to declines in 1-4 family construction loans in the Alabama, Florida, Mississippi and Tennessee market regions.

State and other political subdivision LHFI declined $167.3 million, or 13.7%, during the first nine months of 2023, reflecting declines across all five market regions.

The following table provides information regarding Trustmark’s home equity loans and home equity lines of credit which are included in the LHFI secured by 1-4 family residential properties for the periods presented ($ in thousands):

	September 30, 2023			December 31, 2022
Home equity loans	$	50,310		$	45,532
Home equity lines of credit		420,457			412,013
Percentage of loans and lines for which Trustmark holds first lien		48.5	%		51.7	%
Percentage of loans and lines for which Trustmark does not hold first lien		51.5	%		48.3	%

Due to the increased risk associated with second liens, loan terms and underwriting guidelines differ from those used for products secured by first liens. Loan amounts and loan-to-value ratios are limited and are lower for second liens than first liens. Also, interest rates and maximum amortization periods are adjusted accordingly. In addition, regardless of lien position, the passing credit score for approval of all home equity lines of credit is generally higher than that of term loans. The ACL on LHFI is also reflective of the increased risk related to second liens through application of a greater loss factor to this portion of the portfolio.

Trustmark’s variable rate LHFI are based primarily on various prime and SOFR interest rate bases. The following tables provide information regarding the interest rate terms of Trustmark’s LHFI as of September 30, 2023 and December 31, 2022 ($ in thousands):

Allowance for Credit Losses

LHFI

Trustmark’s ACL methodology for LHFI is based upon guidance within FASB ASC Subtopic 326-20, “Financial Instruments – Credit Losses – Measured at Amortized Cost,” as well as applicable regulatory guidance from its primary regulator. 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 loans. The ACL 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.

79

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.

The econometric models currently in production reflect segment or pool level sensitivities of probability of default (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 its assets, as required by FASB ASC Topic 326. Under stable forecasts, these linear regressions will reasonably predict a pool’s PD. However, due to the COVID-19 pandemic, the macroeconomic variables used for reasonable and supportable forecasting changed rapidly. At the macroeconomic levels experienced during the COVID-19 pandemic, it is not clear that the models currently in production will produce reasonably representative results since the models 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), Southern GDP, Southern Vacancy Rate and the Prime Rate. 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. Due to multiple periods having a PD or loss given default (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.

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 (i.e., natural disasters, changes in legislation, impacts due to technology and pandemics). Trustmark's External Factor – Pandemic ensures reserve adequacy for collectively evaluated loans most likely to be impacted by the unique economic and behavioral conditions created by the COVID-19 pandemic. Additional qualitative reserves are derived based on two principles. The first is the disconnect of economic factors to Trustmark’s modeled PD (derived from the econometric models underpinning the quantitative pooled reserves). During the pandemic, extraordinary measures by the federal government were made available to consumers and businesses, including COVID-19 loan payment concessions, direct transfer payments to households, tax deferrals and reduced interest rates, among others. These government interventions may have extended the lag between economic conditions and default, relative to what was captured in the model development data. Because Trustmark’s econometric PD models rely on the observed relationship from the economic downturn from 2007 to 2009 in both timing and severity, Management does not expect the models to reflect these current conditions. For example, while the models would predict contemporaneous unemployment peaks and loan defaults, this may not occur when borrowers can request payment deferrals. Thus, for the affected population, economic conditions are not fully considered as a part of Trustmark’s quantitative reserve. The second principle is the change in risk that is identified by rating changes. As a part of Trustmark’s credit review process, loans in the affected population have been given more frequent screening to ensure accurate ratings are maintained through this dynamic period. Trustmark’s quantitative reserve does not directly address changes in ratings; thus, a migration qualitative factor was designed to work in concert with the quantitative reserve.

As discussed above, the disconnect of economic factors means that changes in rating caused by deteriorating and weak economic conditions as a result of the pandemic are not being captured in the quantitative reserve. During 2020, due to unforeseen pandemic conditions that varied from Management’s expectations, additional reserves were further dimensioned in order to appropriately reflect the risk within the portfolio related to the COVID-19 pandemic. In an effort to ensure the External Factor – Pandemic qualitative factor is reasonable and supportable, historical Trustmark loss data was leveraged to construct a framework that is quantitative in nature. To dimension the additional reserve, Management uses the sensitivity of the quantitative commercial loan reserve to changes in macroeconomic conditions to apply to loans rated acceptable or better (risk rates 1-4). In addition, to account for the known changes in risk, a weighted average of the commercial loan portfolio loss rate, derived from the performance trends qualitative factor, is used to dimension additional reserves for downgraded credits. Loans rated acceptable with risk (risk rate 5) or watch (risk rate 6) received the additional reserves based on the average of the macroeconomic conditions and weighted average of the commercial loan portfolio loss rate while the loans rated special mention (risk rate 7) and substandard (risk rate 8) received additional reserves based on the weighted-average described above. During the fourth quarter of 2022, Management noted that all pass rate loans (risk rate 5 and 6) related to the External Factor - Pandemic qualitative factor either did not experience significant stress related to the pandemic or have since recovered

80

and does not expect future stresses attributed to the pandemic that may affect these loans. As a result, Management decided to accelerate the release of the additional pandemic reserves on all pass rate loans as a result of pandemic conditions resolving.

During the first quarter of 2022, in order to account for the potential uncertainty related to higher prices and low economic growth, Trustmark chose to enact a portion of the qualitative framework, External Factor - Stagflation. Management calculated the reserve using a third-party stagflation forecast and compared it to the third-party baseline forecast used in the quantitative modeling. The weighted differential was added as qualitative reserves to account for potential uncertainty. During the fourth quarter of 2022, Management determined that the likelihood of a stagflation scenario had sufficiently diminished. Management identified that the potential had already been reduced and effectively captured within a nominally more negative baseline economic forecast. As a result, Management elected to resolve the External Factor - Stagflation and fully release the reserves.

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.

For a complete description of Trustmark’s ACL methodology and the quantitative and qualitative factors included in the calculation, please see Note 3 – LHFI and Allowance for Credit Losses, LHFI included in Part I. Item 1. – Financial Statements of this report.

At September 30, 2023, the ACL on LHFI was $134.0 million, an increase of $13.8 million, or 11.5%, when compared with December 31, 2022. The increase in the ACL during the first nine months of 2023 was principally due to loan growth, weakening in the macroeconomic forecasts, credit downgrades and the nature and volume of the portfolio, partially offset by a decline in specific reserves for individually analyzed LHFI. Allocation of Trustmark’s $134.0 million ACL on LHFI, represented 0.86% of commercial LHFI and 1.66% of consumer and home mortgage LHFI, resulting in an ACL to total LHFI of 1.05% as of September 30, 2023. This compares with an ACL to total LHFI of 0.99% at December 31, 2022, which was allocated to commercial LHFI at 0.85% and to consumer and mortgage LHFI at 1.41%.

The increase in net charge-offs when the three months ended September 30, 2023 is compared to the same time period in 2022 was principally due to increases in gross charge-offs in the Texas and Mississippi market regions, partially offset by an increase in recoveries in the Tennessee market region. The increase in net charge-offs when the first nine months of 2023 is compared to the same time period in 2022 was principally due to increases in gross charge-offs in the Texas and Mississippi market regions as well as a decline in recoveries in the Alabama market region, partially offset by an increase in recoveries in the Tennessee market region.

The following table presents the net (charge-offs) recoveries by geographic market region for the periods presented ($ in thousands):

	Three Months Ended September 30,						Nine Months Ended September 30,
	2023			2022			2023			2022

The PCL, LHFI for the three and nine months ended September 30, 2023 totaled 0.26% and 0.21% of average loans (LHFS and LHFI), respectively, compared to 0.45% and 0.18% of average loans (LHFS and LHFI), respectively, for the same time periods in 2022. The PCL on LHFI for the three and nine months ended September 30, 2023 primarily reflected an increase in required reserves as a result of loan growth, weakening in the macroeconomic forecasts and the net impact of qualitative changes including adjustments to the credit

81

quality trend reserve, the commercial real estate concentration reserve and the nature and volume of the portfolio, partially offset by a decline in specific reserves for individually analyzed LHFI.

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. 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 calculates an expected funding rate each period which is applied to each pool’s unfunded commitment balances to ensure that reserves will be applied to each pool based upon balances expected to be funded based upon historical levels. Additionally, a reserve rate is applied to the unfunded commitment balance, which incorporates both quantitative and qualitative aspects of the current period’s expected credit loss rate. The reserve rate is loan pool specific and is applied to the unfunded amount to ensure loss factors, both quantitative and qualitative, are being considered on the unfunded portion of the loan pool, consistent with the methodology applied to the funded loan pools. See the section captioned “ACL on Off-Balance Sheet Credit Exposures” in Note 12 – Contingencies included in Part I. Item 1. – Financial Statements of this report for complete description of Trustmark’s ACL methodology on 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. At September 30, 2023, the ACL on off-balance sheet credit exposures totaled $34.9 million compared to $36.8 million at December 31, 2022, a decrease of $1.9 million, or 5.1%. The PCL, off-balance sheet credit exposures totaled $104 thousand and a negative $1.9 million for the three and nine months ended September 30, 2023, respectively, compared to a negative $1.3 million and a negative $4.0 million, respectively, for the same time periods in 2022. The PCL on off-balance sheet credit exposures for the three months ended September 30, 2023, primarily reflected an increase in required reserves as a result of changes in the total reserve rate, which was largely offset by a decrease in required reserves due to a decline in unfunded commitments. The release in PCL on off-balance sheet credit exposures for the nine months ended September 30, 2023, primarily reflected a decrease in required reserves due to a decline in unfunded commitments.

Nonperforming Assets

The table below provides the components of nonperforming assets by geographic market region at September 30, 2023 and December 31, 2022 ($ in thousands):

	September 30, 2023			December 31, 2022

Nonaccrual LHFI

At September 30, 2023, nonaccrual LHFI totaled $90.9 million, or 0.70% of total LHFS and LHFI, reflecting an increase of $24.9 million, or 37.8%, relative to December 31, 2022. The increase in nonaccrual LHFI during the first nine months of 2023 was primarily as a result of two large commercial credits placed on nonaccrual that were partially offset by other commercial credits that were foreclosed, charged-off, returned to accrual or paid off.

For additional information regarding nonaccrual LHFI, see the section captioned “Nonaccrual and Past Due LHFI” included in Note 3 – LHFI and Allowance for Credit Losses, LHFI in Part I. Item 1. – Financial Statements of this report.

Other Real Estate

Other real estate at September 30, 2023 increased $3.5 million when compared with December 31, 2022. The increase in other real estate was principally due to one property foreclosed in the Texas market region, partially offset by properties sold in the Mississippi market region.

The following tables illustrate changes in other real estate by geographic market region for the periods presented ($ in thousands):

Other real estate is revalued on an annual basis or more often if market conditions necessitate. Subsequent to foreclosure, losses on the periodic revaluation of the property are charged against the reserve for other real estate write-downs or net income in other real estate expense, if a reserve does not exist. Write-downs of other real estate decreased $481 thousand, or 93.8%, when the first nine months of 2023 is compared to the same time period in 2022, primarily due to a decrease in write-downs as a result of period revaluations of other real estate properties..

Deposits

Trustmark’s deposits are its primary source of funding and consist of core deposits from the communities Trustmark serves. Deposits include interest-bearing and noninterest-bearing demand accounts, savings, money market, certificates of deposit and individual retirement accounts. Total deposits were $15.102 billion at September 30, 2023 compared to $14.438 billion at December 31, 2022, an increase of $664.3 million, or 4.6%. During the first nine months of 2023, noninterest-bearing deposits decreased $773.6 million, or 18.9%, reflecting declines in all categories of noninterest-bearing deposits reflecting customers' desire for higher-yielding deposit accounts. Interest-bearing deposits increased $1.438 billion, or 13.9%, during the first nine months of 2023, primarily due to growth in CDs, which was principally attributable to deposit campaigns offered during the first nine months of 2023 and the addition of $727.3 million of brokered CDs, business and consumer MMDAs and business interest checking accounts, partially offset by declines in public and consumer interest checking accounts and consumer savings accounts.

At September 30, 2023, Trustmark's total uninsured deposits were $5.390 billion, or 35.7% of total deposits, compared to $5.831 billion, or 40.4% of total deposits, at December 31, 2022.

Borrowings

Trustmark uses short-term borrowings, such as federal funds purchased, securities sold under repurchase agreements and short-term FHLB advances, to fund growth of earning assets in excess of deposit growth. See the section captioned “Liquidity” for further discussion of the components of Trustmark’s excess funding capacity.

Federal funds purchased and securities sold under repurchase agreements totaled $321.8 million at September 30, 2023 compared to $449.3 million at December 31, 2022, a decrease of $127.5 million, or 28.4%, principally due to a decrease in upstream federal funds purchased. At September 30, 2023 and December 31, 2022, $51.8 million and $66.3 million represented customer related transactions, such as commercial sweep repurchase balances. Trustmark had $270.0 million of upstream federal funds purchased at September 30, 2023 compared to $383.0 million at December 31, 2022.

Other borrowings totaled $793.2 million at September 30, 2023, a decrease of $257.7 million, or 24.5%, when compared with $1.051 billion at December 31, 2022, principally due to a decline in short-term FHLB advances obtained from the FHLB of Dallas.

Off-Balance Sheet Arrangements

Information required in this section is set forth under the heading “Lending Related” of Note 12 – Contingencies included in Part I. Item 1. – Financial Statements of this report.

Capital Resources and Liquidity

Trustmark places a significant emphasis on the maintenance of a strong capital position, which promotes investor confidence, provides access to funding sources under favorable terms and enhances Trustmark’s ability to capitalize on business growth and acquisition opportunities. Higher levels of liquidity, however, bear corresponding costs, measured in terms of lower yields on short-term, more liquid earning assets and higher expenses for extended liability maturities. Trustmark manages capital based upon risks and growth opportunities as well as regulatory requirements. Trustmark utilizes a capital model in order to provide Management with a monthly tool for analyzing changes in its strategic capital ratios. This allows Management to hold sufficient capital to provide for growth opportunities and protect the balance sheet against sudden adverse market conditions, while maintaining an attractive return on equity to shareholders.

At September 30, 2023, Trustmark’s total shareholders’ equity was $1.570 billion, an increase of $78.1 million, or 5.2%, when compared to December 31, 2022. During the first nine months of 2023, shareholders’ equity increased primarily as a result of net income of $129.4 million, partially offset by common stock dividends of $42.5 million.

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 Trustmark’s 2022 Annual Report, which are administered by the federal

84

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 2.50%. AOCI is not included in computing regulatory capital. Trustmark elected the five-year phase-in transition period (through December 31, 2024) related to adopting FASB ASU 2016-13 for regulatory capital purposes. 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. As of September 30, 2023, Trustmark and TNB exceeded all applicable minimum capital standards. In addition, Trustmark and TNB met applicable regulatory guidelines to be considered well-capitalized at September 30, 2023. To be categorized in this manner, Trustmark and TNB maintained, as applicable, minimum common equity Tier 1 risk-based capital, Tier 1 risk-based capital, total risk-based capital and Tier 1 leverage ratios, 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 September 30, 2023 which Management believes have affected Trustmark’s or TNB’s present classification.

In 2020, Trustmark enhanced its capital structure with the issuance of $125.0 million of subordinated notes. At September 30, 2023 and December 31, 2022, the carrying amount of the subordinated notes was $123.4 million and $123.3 million, respectively. The subordinated notes mature December 1, 2030 and are redeemable at Trustmark’s option under certain circumstances. For regulatory capital purposes, the subordinated notes qualified as Tier 2 capital for Trustmark at September 30, 2023 and December 31, 2022. Trustmark may utilize the full carrying value of the subordinated notes as Tier 2 capital until December 1, 2025 (five years prior to maturity). Beginning December 1, 2025, the subordinated notes will phase out of Tier 2 capital 20.0% each year until maturity.

In 2006, Trustmark enhanced its capital structure with the issuance of trust preferred securities. For regulatory capital purposes, the trust preferred securities qualified as Tier 1 capital at September 30, 2023 and December 31, 2022. Trustmark intends to continue to utilize $60.0 million in trust preferred securities issued by Trustmark Preferred Capital Trust I (the Trust) as Tier 1 capital up to the regulatory limit, as permitted by the grandfather provision in the Dodd-Frank Wall Street Reform and Consumer Protection Act and the Basel III capital rules.

Refer to the section captioned “Regulatory Capital” included in Note 15 – Shareholders’ Equity in Part I. Item 1. – Financial Statements of this report for an illustration of Trustmark’s and TNB’s actual regulatory capital amounts and ratios under regulatory capital standards in effect at September 30, 2023 and December 31, 2022.

Dividends on Common Stock

Dividends per common share for the nine months ended September 30, 2023 and 2022 were $0.69. Trustmark’s indicated dividend for 2023 is $0.92 per common share, which is the same as dividends per common share declared in 2022.

Stock Repurchase Program

From time to time, Trustmark's Board of Directors has authorized stock repurchase plans. In general, stock repurchase plans allow Trustmark to proactively manage its capital position and return excess capital to shareholders. Shares purchased also provide Trustmark with shares of common stock necessary to satisfy obligations related to stock compensation awards.

On December 7, 2021, the Board of Directors of Trustmark authorized a stock repurchase program, effective January 1, 2022, under which $100.0 million of Trustmark’s outstanding common stock could be acquired through December 31, 2022. Under this authority, Trustmark repurchased approximately 789 thousand shares of its common stock value at $24.6 million during 2022.

On December 6, 2022, the Board of Directors of Trustmark authorized a new stock repurchase program, effective January 1, 2023, under which $50.0 million of Trustmark's outstanding common stock may be acquired through December 31, 2023. The repurchase program, which is subject to market conditions and management discretion, will be implemented through open market repurchases or privately negotiated transactions. No shares were repurchased under this authority during the first nine months of 2023.

Liquidity

Liquidity is the ability to ensure that sufficient cash flow and liquid assets are available to satisfy current and future financial obligations, including demand for loans and deposit withdrawals, funding operating costs and other corporate purposes. Consistent cash flows from operations and adequate capital provide internally generated liquidity. Furthermore, Management maintains funding capacity from a variety of external sources to meet daily funding needs, such as those required to meet deposit withdrawals, loan disbursements and security settlements. Liquidity strategy also includes the use of wholesale funding sources to provide for the seasonal fluctuations of

85

deposit and loan demand and the cyclical fluctuations of the economy that impact the availability of funds. Management keeps excess funding capacity available to meet potential demands associated with adverse circumstances.

The asset side of the balance sheet provides liquidity primarily through maturities and cash flows from loans and securities as well as the ability to pledge or sell certain loans and securities. The liability portion of the balance sheet provides liquidity primarily through noninterest and interest-bearing deposits. Trustmark utilizes federal funds purchased, FHLB advances, securities sold under repurchase agreements, the Federal Reserve Discount Window (Discount Window) and brokered deposits to provide additional liquidity. Access to these additional sources represents Trustmark’s incremental borrowing capacity.

Trustmark's liquidity position is continuously monitored and adjustments are made to manage the balance as deemed appropriate. Liquidity risk management is an important element to Trustmark's asset/liability management process. Trustmark regularly models liquidity stress scenarios to assess potential liquidity outflows or funding problems resulting from economic disruptions or other significant occurrences as deemed appropriate by Management. These scenarios are incorporated into Trustmark's contingency funding plan, which provides the basis for the identification of its liquidity needs.

Deposit accounts represent Trustmark’s largest funding source. Average deposits totaled $14.810 billion for the first nine months of 2023 and represented approximately 79.4% of average liabilities and shareholders’ equity, compared to average deposits of $14.887 billion, which represented 85.6% of average liabilities and shareholders’ equity for the first nine months of 2022. The decline in total average deposits when the first nine months of 2023 is compared to the same time period in 2022 was a result of a decline in average noninterest-bearing deposits partially offset by an increase in average interest-bearing deposits, reflecting customers’ desire for higher yielding deposit accounts as well as increased competition for deposits. For more information on average interest-bearing deposits, please see the analysis included in the section captioned “Net Interest Income.”

Trustmark had $486.9 million held in an interest-bearing account at the FRBA at September 30, 2023, compared to $434.0 million held at December 31, 2022.

Trustmark utilizes brokered deposits to supplement other wholesale funding sources. At September 30, 2023, brokered sweep MMDA deposits totaled $12.9 million compared to $15.1 million at December 31, 2022. In addition, Trustmark had $727.3 million of brokered CDs at September 30, 2023 compared to none at December 31, 2022. The increase in brokered CDs during the first nine months of 2023 was primarily due to leveraging comparatively attractive brokered CD pricing as a component of funding loan growth.

At September 30, 2023 Trustmark had $270.0 million of upstream federal funds purchased compared to $383.0 million of upstream federal funds purchased at December 31, 2022. Trustmark maintains adequate federal funds lines to provide sufficient short-term liquidity.

Trustmark maintains a relationship with the FHLB of Dallas, which provided $725.0 million of outstanding short-term and no long-term advances at September 30, 2023, compared to $975.0 million of outstanding short-term and no long-term advances at December 31, 2022. Trustmark had no standby letters of credit outstanding with the FHLB of Dallas at September 30, 2023 and December 31, 2022. Under the existing borrowing agreement, Trustmark had sufficient qualifying collateral to increase FHLB advances or letters of credit with the FHLB of Dallas by $3.595 billion at September 30, 2023.

In addition, at September 30, 2023, Trustmark had no short-term and $63 thousand in long-term FHLB advances outstanding with the FHLB of Atlanta, which were acquired in the BancTrust merger in 2013, compared to no short-term and $78 thousand in long-term FHLB advances at December 31, 2022. Trustmark has non-member status and thus no additional borrowing capacity with the FHLB of Atlanta.

Additionally, Trustmark has the ability to leverage its unencumbered investment securities as collateral. At September 30, 2023, Trustmark had approximately $774.0 million available in unencumbered agency securities compared to $797.0 million in unencumbered Treasury and agency securities at December 31, 2022.

Another borrowing source is the Discount Window. At September 30, 2023, Trustmark had approximately $1.384 billion available in collateral capacity at the Discount Window primarily from pledges of commercial and industrial LHFI, compared with $1.345 billion at December 31, 2022.

Additionally, on March 15, 2020, in response to the COVID-19 pandemic, the FRB reduced reserve requirements for insured depository institutions to zero percent, which increased TNB’s available liquidity.

On March 12, 2023, the U.S. Treasury Department, the FRB and the FDIC jointly announced the establishment of the Bank Term Funding Program (BTFP), in response to recent liquidity concerns within the banking industry in part due to recent deposit runs that

86

resulted in a few large bank failures. The BTFP was designed to provide available additional funding to eligible depository institutions to help assure that banks have the ability to meet the needs of all their depositors. Under the program, eligible depository institutions can obtain loans of up to one year in length by pledging U.S. Treasuries, agency debt and mortgage-backed securities and other qualifying assets (valued at par) as collateral. The BTFP is intended to eliminate the need for depository institutions to quickly sell their securities when they are experiencing stress on their liquidity. As of September 30, 2023, Trustmark had not accessed the BTFP.

During 2020, Trustmark issued $125.0 million aggregate principal amount of its 3.625% fixed-to-floating rate subordinated notes. At September 30, 2023 and December 31, 2022, the carrying amount of the subordinated notes was $123.4 million and $123.3 million, respectively. The subordinated notes mature December 1, 2030 and are redeemable at Trustmark’s option under certain circumstances. The subordinated 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 subordinated notes are obligations of Trustmark only and are not obligations of, and are not guaranteed by, any of its subsidiaries, including TNB.

During 2006, Trustmark completed a private placement of $60.0 million of trust preferred securities through a newly formed Delaware trust affiliate, the Trust. The trust preferred securities mature September 30, 2036 and are redeemable at Trustmark’s option. 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 Board of Directors of Trustmark currently has the authority to issue up to 20.0 million preferred shares with no par value. The ability to issue preferred shares in the future will provide Trustmark with additional financial and management flexibility for general corporate and acquisition purposes. At September 30, 2023, Trustmark had no shares of preferred stock issued and outstanding.

Management believes that Trustmark has sufficient liquidity and capital resources to meet presently known cash flow requirements arising from ongoing business transactions. As of September 30, 2023, Management is not aware of any events that are reasonably likely to have a material adverse effect on Trustmark's liquidity, capital resources or operations. In addition, Management is not aware of any regulatory recommendations regarding liquidity that would have a material adverse effect on Trustmark.

In the ordinary course of business, Trustmark has entered into contractual obligations and has made other commitments to make future payments. Please refer to the accompanying notes to the consolidated financial statements included in Part I. Item 1. – Financial Statements of this report and Trustmark's 2022 Annual Report for the expected timing of such payments as of September 30, 2023 and December 31, 2022. There have been no material changes in Trustmark's contractual obligations since year-end.

Asset/Liability Management

Overview

Market risk reflects the potential risk of loss arising from adverse changes in interest rates and market prices. Trustmark has risk management policies to monitor and limit exposure to market risk. Trustmark’s primary market risk is interest rate risk created by core banking activities. Interest rate risk is the potential variability of the income generated by Trustmark’s financial products or services, which results from changes in various market interest rates. Market rate changes may take the form of absolute shifts, variances in the relationships between different rates and changes in the shape or slope of the interest rate term structure.

Following the LIBOR cessation date of June 30, 2023, the nationwide process for replacing LIBOR in financial contracts that mature thereafter and that do not provide for an effective means to replace LIBOR upon its cessation took effect pursuant to the Adjustable Interest Rate (LIBOR) Act. For contracts in which a party has the discretion to identify a replacement rate, the Adjustable Interest Rate (LIBOR) Act also provides a safe harbor to parties if they choose the SOFR-based benchmark replacement rate to be identified by the FRB. Trustmark had a significant number of loans, derivative contracts, borrowings and other financial instruments with attributes that were either directly or indirectly dependent on LIBOR. As of September 30, 2023, substantially all of Trustmark’s LIBOR exposure was remediated or in the process of being remediated and the remaining LIBOR-based contracts are expected to transition out of LIBOR dependency by year-end 2023. The transition from LIBOR could create costs and additional risk. Trustmark cannot predict what the ultimate impact of the transition from LIBOR will be; however, Trustmark has implemented various measures to manage the transition and mitigate risks. For additional information regarding the transition from LIBOR and Trustmark’s management of this transition, please see the respective risk factor included in Part I. Item 1A. – Risk Factors, of Trustmark’s 2022 Annual Report.

Management continually develops and applies cost-effective strategies to manage these risks. Management’s Asset/Liability Committee sets the day-to-day operating guidelines, approves strategies affecting net interest income and coordinates activities within policy limits established by the Board of Directors of Trustmark. A key objective of the asset/liability management program is to quantify, monitor and manage interest rate risk and to assist Management in maintaining stability in the net interest margin under varying interest rate environments.

87

Derivatives

Trustmark uses financial derivatives for management of interest rate risk. Management’s Asset/Liability Committee, in its oversight role for the management of interest rate risk, approves the use of derivatives in balance sheet hedging strategies. The most common derivatives employed by Trustmark are interest rate lock commitments, forward contracts (both futures contracts and options on futures contracts), interest rate swaps, interest rate caps and interest rate floors. As a general matter, the values of these instruments are designed to be inversely related to the values of the assets that they hedge (i.e., if the value of the hedged asset falls, the value of the related hedge rises). In addition, Trustmark has entered into derivatives contracts as counterparty to one or more customers in connection with loans extended to those customers. These transactions are designed to hedge interest rate, currency or other exposures of the customers and are not entered into by Trustmark for speculative purposes. Increased federal regulation of the derivatives markets may increase the cost to Trustmark to administer derivatives programs.

Derivatives Designated as Hedging Instruments

During the third quarter of 2022, Trustmark initiated a cash flow hedging program. Trustmark's objectives in initiating this hedging program were 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 September 30, 2023, the aggregate notional value of Trustmark's interest rate swaps and floor spreads designated as cash flow hedges totaled $1.000 billion compared to $825.0 million at December 31, 2022.

Trustmark records any gains or losses on these cash flow hedges in AOCI. 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 totaled $13 thousand and $35 thousand of amortization expense for the three and nine months ended September 30, 2023, respectively, and is included in interest and fees on LHFS and LHFI. As interest payments are received on Trustmark's variable-rate assets, amounts reported in AOCI are reclassified into interest and fees on LHFS and LHFI in the accompanying consolidated statements of income during the same period. For the three and nine months ended September 30, 2023, Trustmark reclassified a loss, net of tax, of $3.5 million and $8.7 million, respectively, into interest and fees on LHFS and LHFI compared to a gain, net of tax, of $482 thousand for both the three and nine months ended September 30, 2022. During the next twelve months, Trustmark estimates that $18.4 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

As part of Trustmark’s risk management strategy in the mortgage banking business, various derivative instruments such as interest rate lock commitments and forward sales contracts are utilized. Rate lock commitments are residential mortgage loan commitments with customers, which guarantee a specified interest rate for a specified period of time. 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. The gross notional amount of Trustmark’s off-balance sheet obligations under these derivative instruments totaled $229.8 million at September 30, 2023, with a positive valuation adjustment of $1.7 million, compared to $165.4 million, with a positive valuation adjustment of $325 thousand at December 31, 2022.

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 fair value of the MSR attributable to interest rates. These transactions are considered freestanding derivatives that do not otherwise qualify for hedge accounting under GAAP. The total notional amount of these derivative instruments was $270.0 million at September 30, 2023 compared to $277.0 million at December 31, 2022. 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 the 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 value of 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. The impact of this strategy resulted in a net negative ineffectiveness of $1.0 million and $928 thousand for the three months ended September 30, 2023 and 2022, respectively. For the nine months ended September 30, 2023 and 2022, the impact of this strategy was a net negative ineffectiveness of $4.1 million and $554 thousand, respectively.

Trustmark offers certain interest rate derivatives products directly to qualified commercial lending clients seeking to manage their interest rate risk under loans they have entered into with TNB. 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 under GAAP and are, therefore, carried on Trustmark’s financial statements 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 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. As of September 30, 2023, Trustmark had interest rate swaps with an aggregate notional amount of $1.365 billion related to this program, compared to $1.391 billion as of December 31, 2022.

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 deemed to be in default on its derivatives obligations.

At both September 30, 2023 and December 31, 2022, there was no 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. At September 30, 2023 and December 31, 2022, Trustmark had posted collateral of $40 thousand and $740 thousand, 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 September 30, 2023, it could have been required to settle its obligations under the agreements at the termination value (which is expected to approximate fair market 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 September 30, 2023 and December 31, 2022, Trustmark had entered into five risk participation agreements as a beneficiary with an aggregate notional amount of $49.1 million and $50.2 million, respectively. At September 30, 2023, Trustmark had entered into thirty-four risk participation agreements as a guarantor with an aggregate notional amount of $281.9 million, compared to twenty-nine risk participation agreements as a guarantor with an aggregate notional amount of $235.8 million at December 31, 2022. The aggregate fair values of these risk participation agreements were immaterial at both September 30, 2023 and December 31, 2022.

Trustmark’s participation in the derivatives markets is subject to increased federal regulation of these markets. Trustmark believes that it may continue to use financial derivatives to manage interest rate risk and also to offer derivatives products to certain qualified commercial lending clients in compliance with the Volcker Rule. However, the increased federal regulation of the derivatives markets has increased the cost to Trustmark of administering its derivatives programs. Some of these costs (particularly compliance costs related to the Volcker Rule and other federal regulations) are expected to recur in the future.

Market/Interest Rate Risk Management

The primary purpose in managing interest rate risk is to invest capital effectively and preserve the value created by the core banking business. This is accomplished through the development and implementation of lending, funding, pricing and hedging strategies designed to maximize net interest income performance under varying interest rate environments subject to specific liquidity and interest rate risk guidelines.

Financial simulation models are the primary tools used by Management’s Asset/Liability Committee to measure interest rate exposure. The significant increase in short-term market interest rates and the overall interest rate environment is likely to affect the balance sheet composition and rates. The simulation incorporates assumptions regarding the effects of such changes based on a combination of historical analysis and expected behavior. Using a wide range of scenarios, Management is provided with extensive information on the potential impact on net interest income caused by changes in interest rates. Models are structured to simulate cash flows and accrual characteristics of Trustmark’s balance sheet. Assumptions are made about the direction and volatility of interest rates, the slope of the yield curve and the changing composition of Trustmark’s balance sheet, resulting from both strategic plans and customer behavior. In addition, the model incorporates Management’s assumptions and expectations regarding such factors as loan and deposit growth, pricing, prepayment speeds and spreads between interest rates.

Based on the results of the simulation models using static balances, the table below summarizes the effect various one-year interest rate shift scenarios would have on net interest income compared to a base case, flat scenario at September 30, 2023 and 2022. Given the substantial increase in market rates, the down 200 basis points scenario has been added to the table below for the nine months ended September 30, 2023.

	Estimated % Change in Net Interest Income
Change in Interest Rates	2023			2022
+200 basis points		2.0	%		5.4	%
+100 basis points		1.0	%		2.7	%
-100 basis points		-1.2	%		-5.8	%
-200 basis points		-2.8	%		—

Management cannot provide any assurance about the actual effect of changes in interest rates on net interest income. The estimates provided do not include the effects of possible strategic changes in the balances of various assets and liabilities throughout 2023 or additional actions Trustmark could undertake in response to changes in interest rates. Management will continue to prudently manage the balance sheet in an effort to control interest rate risk and maintain profitability over the long term.

Another component of interest rate risk management is measuring the economic value-at-risk for a given change in market interest rates. The economic value-at-risk may indicate risks associated with longer-term balance sheet items that may not affect net interest income at risk over shorter time periods. Trustmark uses computer-modeling techniques to determine the present value of all asset and liability cash flows (both on- and off-balance sheet), adjusted for prepayment expectations, using a market discount rate. The economic value of equity (EVE), also known as net portfolio value, is defined as the difference between the present value of asset cash flows and the present value of liability cash flows. The resulting change in EVE in different market rate environments, from the base case scenario, is the amount of EVE at risk from those rate environments.

The following table summarizes the effect that various interest rate shifts would have on net portfolio value at September 30, 2023 and 2022.

	Estimated % Change in Net Portfolio Value
Change in Interest Rates	2023			2022
+200 basis points		-2.7	%		-0.1	%
+100 basis points		-1.2	%		0.1	%

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. The model incorporates assumptions that market participants use in estimating future net servicing income, including estimates of prepayment speeds, discount rate, default rates, cost to service (including delinquency and foreclosure costs), escrow account earnings, contractual servicing fee income and other ancillary income such as late fees. Management reviews all significant assumptions quarterly. Mortgage loan prepayment speeds, a key assumption in the model, is the annual rate at which borrowers are forecasted to repay their mortgage loan principal. The discount rate used to determine the present value of estimated future net servicing income, another key assumption in the model, is an estimate of the required rate of return investors in the market would require for an asset with similar risk. Both assumptions can, and generally will, change as market conditions and interest rates change.

By way of example, an increase in either the prepayment speed 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. In recent years, there have been significant market-driven fluctuations in loan prepayment speeds and discount rates. These fluctuations can be rapid and may continue to be significant. Therefore, estimating prepayment speed and/or discount rates within ranges that market participants would use in determining the fair value of the MSR requires significant management judgment.

At September 30, 2023, the MSR fair value was $142.4 million, compared to $132.6 million at September 30, 2022. The impact on the MSR fair value of a 10% adverse change in prepayment speed or a 100 basis point increase in discount rate at September 30, 2023, would be a decline in fair value of approximately $5.0 million and $6.0 million, respectively, compared to a decline in fair value of approximately $4.7 million and $5.7 million, respectively, at September 30, 2022. Changes of equal magnitude in the opposite direction would produce similar increases in fair value in the respective amounts.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Information required in this section is set forth under the heading “Legal Proceedings” of Note 12 – Contingencies in Part I. Item 1 – Financial Statements of this report.

In accordance with FASB Accounting Standards Codification (ASC) Topic 450-20, “Loss Contingencies,” Trustmark will establish an accrued liability for litigation matters when those matters present 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 such proceeding is not probable and reasonably estimable. All matters will continue to be monitored for further developments that would make such loss contingency both probable and reasonably estimable. In view of the inherent difficulty of predicting the outcome of legal proceedings, Trustmark cannot predict the eventual outcomes of the currently pending matters or the timing of their ultimate resolution. Trustmark currently believes, however, based upon the advice of legal counsel and Management’s evaluation and after taking into account its current insurance coverage, that the legal proceedings currently pending should not have a material adverse effect on Trustmark’s consolidated financial condition.
