**PART I**

**ITEM 1. BUSINESS**

**The Corporation**

***Description of Business***

Trustmark Corporation (Trustmark), a Mississippi business corporation incorporated in 1968, is a bank holding company headquartered in Jackson, Mississippi. As previously disclosed, on August 4, 2025, Trustmark's principal subsidiary, Trustmark National Bank, initially chartered by the State of Mississippi in 1889, converted from a national banking association to a Mississippi-chartered banking corporation and changed its name to Trustmark Bank (TB). TB is a member bank of the Federal Reserve System and is supervised by the Federal Reserve Bank of Atlanta (FRBA) and the Mississippi Department of Banking and Consumer Finance (MDBCF).

***Overview of Lending Business***

Trustmark categorizes loans on its balance sheet into two categories. These categories are described in more detail in Note 1 – Significant Accounting Policies included in Part II. Item 8. – Financial Statements and Supplementary Data of this report.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Loans Held for Investment (LHFI)* – Loans originally underwritten by Trustmark that do not constitute loans held for sale or acquired loans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Loans Held for Sale (LHFS)* – Mortgage loans purchased from wholesale customers or originated in Trustmark's General Banking Segment, other than mortgage loans that are retained in the LHFI portfolio based on banking relationships or certain investment strategies.

Trustmark reports LHFI by its six geographic market regions based on the location of the loan origination with the exception of loans secured by 1-4 family residential properties (representing traditional mortgages) and credit cards. Loans secured by 1-4 family residential properties and credit cards are reported in the Mississippi market region because they are centrally analyzed and approved as part of a specific line of business located at Trustmark's headquarters in Jackson, Mississippi. The related construction project, property or collateral may be located outside of Trustmark's six geographic market regions but are primarily within its defined trade area. Equipment finance loans and leases are primarily reported in the Georgia market region because they are centrally analyzed and approved as part of the Equipment Finance line of business which is a nationwide line of business located in Atlanta, Georgia.

The following discussion briefly summarizes Trustmark's lending business by focusing on LHFI and LHFS and includes a discussion of the risks inherent in these loans, Trustmark's underwriting policies for its loans and the characteristics of the real estate loan component of these loans.

As a general matter, extending credit to businesses and consumers exposes Trustmark to credit risk, which is the risk that the principal balance and any related interest may not be collected according to the original terms due to the inability or unwillingness of the borrower

------

to repay the loan. Trustmark mitigates credit risk through a set of internal controls, which includes adherence to conservative lending practices and underwriting guidelines, collateral monitoring, and oversight of its borrower's financial performance and collateral. The risks inherent in specific subsets of lending are discussed below.

*LHFI Secured by Construction, Land Development, and Other Land* – Construction and land development loans include loans for both commercial and residential properties to builders/developers, other commercial borrowers and consumers. This category also includes loans secured by vacant land, except land known to be used or usable for agricultural purposes, such as crop and livestock production. Repayment is normally derived from the sale of the underlying property or from permanent financing, which refinances Trustmark's initial loan. Trustmark's engagement in this type of lending is generally extended to those builders and developers exhibiting the highest credit quality with significant equity invested in the projects which are primarily located within Trustmark's defined trade area. 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 and availability of permanent financing. Risk within this portfolio is mitigated through adherence to policies and lending limits, periodic target credit reviews of the different segments of this portfolio, inspection of projects throughout the life of the loan and routine monitoring of financial information and collateral values as they are updated.

Inherent in real estate construction lending is the risk that the full value of the collateral does not exist at the time the loan is granted. Construction lending also inherently includes the risk associated with a borrower's ability to successfully complete a proposed project on time and within budget. Further, adverse changes in the market occurring between the start of construction and completion of the projects can result in slower sales or rental rates and lower sales prices than originally anticipated, which could impact the underlying real estate collateral values and timely and full repayment of these loans. Rising interest rates can adversely affect the cost of construction and the financial viability of real estate projects. Higher interest rates may also result in higher capitalization rates, thereby reducing a property's value. As a result of this risk profile, LHFI secured by construction, land development and other land are considered to be higher risks than other real estate loans.

*LHFI and LHFS Secured by Residential Properties* – Residential real estate loans consist of first and junior liens on residential properties that are primarily extended in the defined trade area in which Trustmark operates as well as mortgage products, originated and purchased, that are underwritten to secondary market standards. Credit underwriting standards include evaluation of the borrower's credit history and repayment capacity, including verification of income and valuation of collateral. Portfolio performance is continuously evaluated through monitoring of repayment performance.

Credit performance of consumer residential real estate loans is highly dependent on housing values and household income which, in turn are highly dependent on national, regional and local economic factors. Rising interest rates, rising unemployment rates and other adverse changes in these economies may have a negative effect on the ability of Trustmark's borrowers to repay these loans and negatively affect value of the underlying residential real estate collateral.

*LHFI Secured by Nonfarm, Nonresidential Properties (NFNR LHFI)* – Trustmark provides financing for both owner-occupied commercial real estate as well as income-producing commercial real estate. Trustmark seeks to maintain a balance of owner-occupied and income-producing real estate loans that moderates its risk to the specific risks of each type of loan. Commercial real estate term loans are typically collateralized by liens on real property. Both types of commercial real estate loans are underwritten to lending policies that include maximum loan-to-value ratios, minimum equity requirements, acceptable amortization periods and minimum debt service coverage requirements, based on property type. Income-producing commercial real estate loans also generally require substantial equity and are subject to exposure limits for a single project. All exceptions to established guidelines are subject to stringent internal review and require specific approval. As with commercial loans, 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.

Risk for owner-occupied commercial real estate is driven by the creditworthiness of the underlying borrowers, particularly cash flow from the borrowers' business operations as well as the risk of a shortfall in collateral. Credit performance of loans secured by commercial income-producing real estate can be negatively affected by national, regional and local economic conditions, which may result in deteriorating tenant credit profiles, tenant losses, reduced rental/lease rates and higher than anticipated vacancy rates, all contributing to declines in value or liquidity of the underlying real estate collateral. Other factors, such as increasing interest rates, may result in higher capitalization rates, thereby reducing a property's value.

*Commercial and Industrial LHFI* – Commercial loans (other than commercial loans related to real estate assets, which are summarized above) are 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, equipment and fixed asset purchases that are secured by those assets and term financing for those

------

within Trustmark's defined trade area. Trustmark's credit underwriting process for commercial 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. Credit risk within the commercial loan portfolio is managed through adherence to specific commercial lending policies and internally established lending authorities, diversification within the portfolio and monitoring of the portfolio on a continuing basis.

Credit risk in commercial and industrial loans can arise due to fluctuations in borrowers' financial condition, deterioration in collateral values and changes in market conditions. The credit risk inherent in these loans depends on, to a significant degree, the general economic conditions of these areas. Further, credit risk can increase if Trustmark's loans are concentrated to borrowers engaged in the same or similar activities, or to groups of borrowers who may be uniquely or disproportionately affected by market or economic conditions.

*Consumer LHFI* – Consumer credit includes loans to individuals for household and personal items, automobile purchases, unsecured loans, personal lines of credit and credit cards. All consumer loans are subject to a standardized underwriting process through Trustmark's consumer loan center, with emphasis placed upon the borrower's credit evaluation and historical performance, income evaluation and valuation of collateral (where applicable).

Similar to residential real estate loan portfolios, an inherent risk factor in consumer loans is that they are dependent on national, regional and local economic factors that affect employment in the markets where these loans are originated. Generally, consumer loan portfolios consist of a large number of relatively small-balance loans, some of which are originated as unsecured credit (credit cards and some personal lines of credit), and as such, do not have collateral as a secondary source of repayment. Consumer loans generally pose heightened risks of collectability and loss when compared to other loan types.

*Other Commercial LHFI* – Other loans include 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. Other commercial LHFI also include leases of machinery and equipment to commercial customers. These leases are underwritten based on the specific nature or purpose of the lease and underlying collateral with special consideration given to the specific source of repayment for the lease.

Similar to commercial and industrial loans, inherent risk in other commercial loans and leases can arise due to fluctuations in the borrower's or lessee's financial condition, deterioration in collateral values and changes in market and economic conditions. Loans to state and political subdivisions have the added inherent risk of being somewhat dependent on the ability and capacity of those entities to generate tax and other revenue to repay the loans. Loans to non-profit and charitable organizations are dependent on those organizations' ability to generate revenue through their fundraising efforts and other forms of financial support, which can be susceptible to economic downturns.

***Recent Economic and Industry Developments***

Economic activity improved slightly during 2025, but was characterized by mixed signals, notably, strong equity market performance, continued consumer spending and FRB rate cuts, but also a softening labor market and persistent inflationary pressures, driven partly by new tariffs. United States stocks performed strongly during the second half of 2025, supported by optimistic sentiment around lower interest rates, better-than-expected corporate earnings and strong performance in the technology and artificial intelligence (AI) sectors. However, economic concerns remain as a result of the cumulative weight of uncertainty regarding the potential economic impact of geopolitical developments, such as conflicts in Ukraine and the Middle East, the current United States presidential administration's policies, inflationary and broader pricing pressures and other economic and industry volatility. Concerns surrounding the 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.

For most of 2025, the FRB left the target federal funds rate unchanged at a range of 4.25% to 4.50% and maintained the rate it pays on reserves at 4.40%. However, beginning with the September 2025 meeting of the FRB's Federal Open Market Committee, the FRB noted increases in unemployment and inflation shifting the balance of risks to achieving its goals. As a result, the FRB decreased the target federal funds rate and the rate it pays on reserves multiple times during the fourth quarter of 2025, lowering the target federal funds rate to a range of 3.50% to 3.75% and the rate it pays on reserves to 3.65% as of December 2025. At the most recent meeting of the FRB's Federal Open Market Committee (in January 2026), the FRB determined to leave the target federal funds rate and the rate it pays on reserves unchanged. Prior period rate increases increased the competitive pressures on the deposit cost of funds. While rate cuts potentially reduced those competitive pressures, they increased pressure on Trustmark's net interest margin, a key component to its financial results. It is not possible to predict the direction, pace or magnitude of further changes, if any, in interest rates, or the impact any such rate changes will have on Trustmark's results of operations.

In the November 2025 and January 2026 "Summary of Commentary on Current Economic Conditions by Federal Reserve District," the twelve Federal Reserve Districts' reports suggested that during the reporting periods (covering the period from October 6, 2025 through November 17, 2025 and November 18, 2025 through January 5, 2026) economic activity increased at a slight to modest pace. Reports by the twelve Federal Reserve Districts (Districts) noted the following during the reporting periods:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Most Districts reported slight to modest growth in consumer spending, largely attributed to the holiday shopping season. Several Districts also noted that spending was stronger among higher-income consumers, while low to moderate income consumers were increasingly price sensitive and hesitant to spend on nonessential goods and services. Auto sales were little changed to down across most Districts.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Manufacturing activity varied with approximately half the Districts reporting growth and approximately half reporting contraction. Nonfinancial services demand was generally seen as steady to increasing somewhat. Agriculture conditions were largely unchanged with only Federal Reserve's Sixth District, Atlanta, reporting a modest decline due to weaker demand for exported commodities. Energy demand and production was flat to down slightly, with some contacts citing challenges from the low-price environment for oil. Community organizations saw increased demand for food assistance, due in part to disruptions in SNAP benefits during the government shutdown.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Banking conditions were generally reported as stable or improving, with some increased demand coming from credit cards, home equity loans and commercial lending. Residential real estate sales, construction and lending activity softened in the majority of Districts that report on the sector.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Outlooks for future activity were mildly optimistic with most expecting slight to modest growth in the short term.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Districts reported that employment declined slightly in the November 2025 report and was mostly unchanged in the January 2026 report. Despite an uptick in layoff announcements, more Districts reported contacts limiting headcounts using hiring freezes, replacement-only hiring and attrition than through layoffs. Several employers adjusted hours worked to accommodate higher or lower than expected business volume instead of adjusting the number of employees. Multiple Districts reported an increase in the usage of temporary workers. Firms continued to report challenges finding skilled labor, particularly in engineering, health care and other trades. Multiple contacts reported exploring AI implementation primarily for productivity enhancement and potential future workforce management. AI's current impact on employment was limited, with more significant effects anticipated in the coming years rather than immediately. Wages grew at a moderate pace, though rising health insurance premiums continued to put upward pressure on labor costs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Prices grew at a moderate rate. Cost pressures due to tariffs were a consistent theme across all Districts. Several contacts that had initially absorbed tariff-related costs were beginning to pass them on to customers as pre-tariff inventories became depleted or as pressures to preserve margins grew more acute. Contacts in some industries, such as retail and restaurants, were reluctant to pass costs along to price-sensitive customers. Rising costs for energy, insurance, technology and health care continued to be a significant strain on margins. Firms expect some moderation in price growth, but anticipate prices to remain elevated as they work through increased costs.

Reports by the Federal Reserve's Sixth District, Atlanta (which includes Trustmark's Alabama, Florida, Georgia 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 periods as those discussed above. The Federal Reserve's Sixth District also noted modest loan growth, with the largest increases in the credit card segment, and declines in auto and other consumer loans reflecting consumer uncertainty. The Federal Reserve's Sixth District reported that delinquencies continued to fall in aggregate, though several financial institutions reported a marginal uptick, and cash to total assets ratios increased moderately on balance, allowing for ample liquidity to meet customers' needs. The Federal Reserve's Eighth District also reported banking activity increased modestly with overall loan activity much stronger than one year ago, particularly among real estate loans and home-equity lines of credit, and modest growth in commercial and industrial loans, while consumer lending was slightly lower than one year ago. The Federal Reserve's Eighth District also noted that contacts reported meaningfully tighter lending standards on business loans and overall deposits ended the year modestly higher than one year ago. The Federal Reserve's Eleventh District also reported loan volume and demand increased in December 2025 after decreasing in November 2025, driven by increases in commercial real estate loans, credit standards and terms tightened, though loan pricing continued to decline, loan performance deteriorated at a slower pace overall and bankers reported increasing general business activity. The Federal Reserve's Eleventh District noted that outlooks leaned optimistic, with contacts expecting growth in loan demand and business activity in the next six months but a slight deterioration in loan performance.

Trustmark is intently monitoring the impact of tariffs and other administrative policies on its customer base, interest rates and credit-related issues. Economic uncertainty or disruptions in the marketplace as a result of such policies could reduce loan demand or increase

loan nonperformance. It is not possible to predict the timing or magnitude of changes to policies by the current United States presidential administration, if any, or the impact any such policy changes could have on Trustmark's customer base, credit quality or results of operations.

For additional discussion of the impact of the current economic environment on the financial condition and results of operations of Trustmark and its subsidiaries, see Part II. Item 7. – Management's Discussion and Analysis of Financial Condition and Results of Operations of this report.

***Competition***

There is significant competition within the banking and financial services industry in the markets in which Trustmark operates. Changes in regulation, technology and product delivery systems have resulted in an increasingly competitive environment. Trustmark expects to continue to face increasing competition from online and traditional financial institutions seeking to attract customers by providing access to similar services and products.

Trustmark and its subsidiaries compete with national and state-chartered banking institutions of comparable or larger size and resources and with smaller community banking organizations. Trustmark has numerous local, regional and national nonbank competitors, including savings and loan associations, credit unions, mortgage companies, finance companies, financial service operations of major retailers, investment brokerage and financial advisory firms and mutual fund companies. Because nonbank financial institutions are not subject to the same regulatory restrictions as banks and bank holding companies, they can often operate with greater flexibility and lower cost structures. Currently, Trustmark does not face meaningful competition from international banks in its markets, although that could change in the future.

At June 30, 2025, Trustmark's deposit market share ranked within the top three positions in 52.0% of the 56 counties served and within the top five positions in 68.0% of the counties served. The following table presents Federal Deposit Insurance Corporation (FDIC) deposit data regarding TB's deposit market share by state as of June 30, 2025. The FDIC deposit market share data presented below does not align with Trustmark's reported geographic market regions, which in some instances cross state lines, and Trustmark's geographic coverage within certain states presented below is not statewide (see the section captioned "Description of Business" above).

---

| | |
|:---|:---|
| State | Deposit Market Share |
| &nbsp;&nbsp;&nbsp;&nbsp;Alabama | 1.87% |
| &nbsp;&nbsp;&nbsp;&nbsp;Florida | 0.17% |
| &nbsp;&nbsp;&nbsp;&nbsp;Mississippi | 12.17% |
| &nbsp;&nbsp;&nbsp;&nbsp;Tennessee | 0.30% |
| &nbsp;&nbsp;&nbsp;&nbsp;Texas | 0.04% |

---

Services provided by the Wealth Management Segment face competition from many national, regional and local financial institutions. Companies that offer broad services similar to those provided by Trustmark, such as other banks, trust companies and full-service brokerage firms, as well as companies that specialize in particular services offered by Trustmark, such as investment advisors and mutual fund providers, all compete with Trustmark's Wealth Management Segment.

Trustmark's ability to compete effectively is a result of providing customers with desired products and services in a convenient and cost-effective manner. Customers for commercial, consumer and mortgage banking as well as wealth management services are influenced by convenience, quality of service, personal contacts, availability of products and services and competitive pricing. Trustmark continually reviews its products, locations, alternative delivery channels, and pricing strategies to maintain and enhance its competitive position. While Trustmark's position varies by market, Management believes it can compete effectively as a result of the quality of Trustmark's products and services, local market knowledge and awareness of customer needs.

**Supervision and Regulation**

The following discussion sets forth material elements of the regulatory framework applicable to bank holding companies and their subsidiaries and provides specific information relevant to Trustmark. The discussion is a summary of detailed statutes, regulations and policies. The descriptions are not intended to be complete summaries of the statutes, regulations and policies referenced therein. Such statutes, regulations and policies are continually under the review of the United States Congress and state legislatures as well as federal and state regulatory agencies. A change in statutes, regulations or policies could have a material impact on the business of Trustmark and its subsidiaries.

------

***Regulation of Trustmark***

Trustmark is a registered bank holding company under the Bank Holding Company Act of 1956 (BHC Act). Trustmark and its nonbank subsidiaries are therefore subject to the supervision, examination, enforcement and reporting requirements of the BHC Act, the Federal Deposit Insurance Act (FDI Act), the regulations of the FRB and certain of the requirements imposed by the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act), as amended by the Economic Growth, Regulatory Relief and Consumer Protection Act (EGRRCPA).

*Federal Oversight Over Mergers and Acquisitions, Investments and Branching*

The BHC Act requires every bank holding company to obtain the prior approval of the FRB before: (i) it may acquire direct or indirect ownership or control of any voting shares of any bank if, after such acquisition, the bank holding company will directly or indirectly own or control 5.0% or more of the voting shares of the bank; (ii) it or any of its subsidiaries, other than a bank, may acquire all or substantially all of the assets of any bank; or (iii) it may merge or consolidate with any other bank holding company. The BHC Act further requires the FRB to consider the competitive impact of the transaction, the financial and managerial resources and future prospects of the bank holding companies and banks concerned and the convenience and needs of the community to be served, including the applicant's record of performance under the Community Reinvestment Act (CRA). The FRB is also required to take into account in evaluating such a transaction the effectiveness of the parties in combating money laundering activities. Provisions of the FDI Act known as the Bank Merger Act impose similar approval standards for an insured depository institution to merge with another insured depository institution.

In September 2024, the U.S. Department of Justice (DOJ) withdrew from its 1995 Bank Merger Guidelines and announced that it will instead evaluate the competitive impact of bank mergers using its 2023 Merger Guidelines that apply across all industries. Compared to the 1995 Bank Merger Guidelines, the 2023 Merger Guidelines set forth more stringent concentration limits and add several largely qualitative bases on which the DOJ may challenge a merger. This change in the DOJ's bank merger antitrust policy creates uncertainty regarding the types of transactions that the DOJ may challenge as anticompetitive.

The BHC Act, as amended by the interstate banking provisions of the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 (Riegle-Neal Act), permits a bank holding company, such as Trustmark, to acquire a bank located in any other state, regardless of state law to the contrary, subject to certain deposit-percentage, aging requirements, and other restrictions, if the company is well-capitalized. The Riegle-Neal Act also generally permits national and state-chartered banks to branch interstate through acquisitions of banks in other states, if the resulting institution would be well-capitalized and well-managed.

In addition, the FRB has the authority to approve applications by state member banks to establish *de novo* branches, including, under the Riegle-Neal Act, in states other than the bank's home state if the law of the state in which the branch is located, or is to be located, would permit establishment of the branch if the bank were a state bank chartered by such state.

The BHC Act also generally requires FRB approval for a bank holding company's acquisition of a company that is not an insured depository institution. Bank holding companies generally may engage, directly or indirectly, only in banking and such other activities as are determined by the FRB to be closely related to banking. Additionally, a provision of the BHC Act known as the Volcker Rule places limits on the ability of Trustmark and TB to acquire or retain ownership interests in, or act as sponsor to, certain investment funds, including hedge funds and private equity funds, or to engage in proprietary trading (*i.e.*, engaging as principal in any purchase or sale of one or more financial instruments for a trading account).

Certain acquisitions of Trustmark's voting stock may be subject to regulatory approval or notice under federal law. Under the Change in Bank Control Act and BHC Act, a person or company that directly or indirectly acquires control of a bank holding company or bank must obtain the non-objection or approval of the institution's appropriate federal banking agency in advance of the acquisition. For a publicly-traded bank holding company such as Trustmark, control for purposes of the Change in Bank Control Act is presumed to exist if the acquirer will have 10% or more of any class of the company's voting securities.

*Source of Strength*

Under the FDI Act, Trustmark is expected to act as a source of financial and managerial strength to TB. Under this policy, a bank holding company is expected to commit resources to support its bank subsidiary, including at times when the holding company may not be inclined or in a financial position to provide it.

------

*Capital Adequacy*

Bank holding companies and banks are subject to various regulatory capital requirements administered by state and federal bank regulatory agencies. Capital adequacy regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weighting and other factors. The FRB has established substantially similar minimum risk-based capital ratio and leverage ratio requirements for bank holding companies and banks.

Under capital requirements applicable to Trustmark and TB, Trustmark and TB are required to meet a common equity Tier 1 capital to risk-weighted assets ratio of at least 7.0% (a minimum of 4.5% plus a capital conservation buffer of 2.5%), a Tier 1 capital to risk-weighted assets ratio of at least 8.5% (a minimum of 6.0% plus a capital conservation buffer of 2.5%), a total capital to risk-weighted assets ratio of at least 10.5% (a minimum of 8.0% plus a capital conservation buffer of 2.5%), and a leverage ratio of Tier 1 capital to total consolidated assets of at least 4.0%.

For purposes of calculating the denominator of the risk-based capital ratios, a banking institution's assets and some of its specified off-balance sheet commitments and obligations are assigned to various risk categories. For purposes of calculating the numerator of the capital ratios, capital, at both the holding company and bank level, is classified in one of three tiers depending on the "quality" and loss-absorbing features of the capital instrument. Common equity Tier 1 capital is predominantly comprised of common stock instruments (including related surplus) and retained earnings, net of treasury stock, and after making necessary capital deductions and adjustments. Tier 1 capital is comprised of common equity Tier 1 capital and additional Tier 1 capital, which includes non-cumulative perpetual preferred stock and similar instruments meeting specified eligibility criteria (including related surplus). Newly issued trust preferred securities and cumulative perpetual preferred stock may not be included in Tier 1 capital. Smaller depository institution holding companies (those with assets of less than $15 billion as of year-end 2009, including Trustmark) and most mutual holding companies are generally allowed to continue to count as Tier 1 capital most outstanding trust preferred securities and other non-qualifying securities that were issued prior to May 19, 2010 (up to a limit of 25% of Tier 1 capital, excluding non-qualifying capital instruments) rather than phasing such securities out of regulatory capital. However, a smaller depository institution holding company that has $15 billion or more in assets following an acquisition of another depository institution holding company generally is no longer allowed to count outstanding non-qualifying capital instruments toward its Tier 1 capital. Trustmark currently has outstanding trust preferred securities that are permitted to continue to count as Tier 1 capital up to the regulatory limit. Total capital is comprised of Tier 1 capital and Tier 2 capital, which includes certain subordinated debt with a minimum original maturity of five years (including related surplus) and a limited amount of allowance for loan losses. Newly issued trust preferred securities and cumulative perpetual preferred stock generally may be included in Tier 2 capital, provided they do not include features that are disallowed by the capital rules, such as the acceleration of principal other than in the event of a bankruptcy, insolvency, or receivership of the issuer.

Failure to meet minimum capital requirements could subject a bank to a variety of enforcement remedies, including issuance of a capital directive, the termination of deposit insurance by the FDIC and certain other restrictions on its business. An institution's failure to exceed the capital conservation buffer with common equity Tier 1 capital would result in limitations on an institution's ability to make capital distributions and discretionary bonus payments.

In addition, the FDI Act's "prompt corrective action" framework identifies five capital categories for insured depository institutions: well-capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. For an insured depository institution to be "well-capitalized," it must have a common equity Tier 1 capital ratio of at least 6.5%, a Tier 1 capital ratio of at least 8.0%, a total capital ratio of at least 10.0% and a leverage ratio of at least 5.0%, and must not be subject to any written agreement, order or capital directive or prompt corrective action directive issued by its primary federal regulator to meet and maintain a specific capital level for any capital measure. An insured depository institution is subject to differential regulation corresponding to the capital category within which the institution falls. For example, an insured depository institution is generally prohibited from making capital distributions, including paying dividends, or paying management fees to a holding company, if the institution would thereafter be undercapitalized.

At December 31, 2025, Trustmark exceeded its minimum capital requirements with common equity Tier 1 capital, Tier 1 capital and total capital equal to 11.72%, 12.11% and 14.41% of its total risk-weighted assets, respectively. At December 31, 2025, TB also exceeded these requirements with common equity Tier 1 capital, Tier 1 capital and total capital equal to 12.33%, 12.33% and 13.52% of its total risk-weighted assets, respectively. At December 31, 2025, the leverage ratios for Trustmark and TB were 10.18% and 10.37%, respectively. At December 31, 2025, TB was well-capitalized based on the ratios and guidelines described above.

In December 2018, the federal banking agencies issued a final rule that allowed institutions to elect to phase in the regulatory capital effects of the Current Expected Credit Losses (CECL) accounting standard over three years. In addition, as a result of the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act) enacted on March 27, 2020 in response to the COVID-19 pandemic, the federal bank regulatory agencies issued rules that allowed banking organizations that implemented CECL in 2020 to elect to mitigate

------

the effects of the CECL accounting standard on their regulatory capital for two years. This two-year delay was in addition to the three-year transition period that the agencies had already made available. Trustmark elected to defer the regulatory capital effects of CECL in accordance with these rules, which largely delayed the effects of the adoption of CECL on its regulatory capital through December 31, 2021. The effects were phased-in over a three-year period from January 1, 2022 through December 31, 2024.

*Payment of Dividends and Stock Repurchases*

Trustmark is limited in its ability to pay dividends or repurchase its stock by the FRB, including if doing so would be an unsafe or unsound banking practice. In addition, the FRB has adopted the policy that a bank holding company should pay cash dividends only to the extent that the company's net income for the past year is sufficient to cover the cash dividends, and that the company's rate of earning retention is consistent with the company's capital needs, asset quality and overall financial condition. In addition, a bank holding company is required to consult with or notify the FRB prior to purchasing or redeeming its outstanding equity securities in certain circumstances, including if the gross consideration for the purchase or redemption, when aggregated with the net consideration paid by the company for all such purchases or redemptions during the preceding twelve months, is equal to 10% or more of the company's consolidated net worth. A bank holding company that is well-capitalized, well-managed and not the subject of any unresolved supervisory issues is exempt from this notice requirement.

*Anti-Money Laundering (AML) Initiatives and Sanctions Compliance*

Trustmark and TB are subject to extensive laws and regulations aimed at combating money laundering and terrorist financing, including the USA Patriot Act of 2001 (USA Patriot Act) and the Bank Secrecy Act. Regulations implementing these statutes impose obligations on financial institutions to maintain appropriate policies, procedures and controls to detect, prevent and report money laundering and terrorist financing and to verify the identity of their customers and of beneficial owners of their legal entity customers. Failure of a financial institution to maintain and implement adequate programs to combat money laundering and terrorist financing, or to comply with all of the relevant laws or regulations, could have serious legal and financial consequences for the institution. The federal Financial Crimes Enforcement Network of the Department of the Treasury, in addition to federal bank regulatory agencies, is authorized to impose significant civil money penalties for violations of these requirements, and has recently engaged in coordinated enforcement efforts with state and federal banking regulators, the DOJ, the Consumer Financial Protection Bureau (CFPB), the Drug Enforcement Administration and the Internal Revenue Service. Violations of AML requirements can also lead to criminal penalties. In addition, the federal banking agencies are required to consider the effectiveness of a financial institution's AML activities when reviewing proposed bank mergers and bank holding company acquisitions.

The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) is responsible for helping to ensure that U.S. entities do not engage in transactions with certain prohibited parties, as defined by various Executive Orders and Acts of Congress. OFAC administers and enforces economic and trade sanctions programs, including publishing lists of persons, organizations, and countries suspected of aiding, harboring or engaging in terrorist acts, known as Specially Designated Nationals and Blocked Persons. OFAC regulations generally require either the blocking of accounts or other property of specified entities or individuals, but they may also require the rejection of certain transactions involving specified entities or individuals. Trustmark maintains policies, procedures and other internal controls designed to comply with these sanctions programs.

*Other Federal Regulation of Trustmark*

In addition to being regulated as a bank holding company, Trustmark is subject to regulation by the State of Mississippi under its general business corporation laws. Trustmark is also subject to the disclosure and other regulatory requirements of the Securities Act of 1933 and the Securities Exchange Act of 1934, as administered by the SEC.

***Regulation of TB***

TB is a Mississippi state-chartered bank and a member of the Federal Reserve System and its deposits are insured by the FDIC. As such, TB is subject to extensive regulation by the FRB, the MDBCF and, to a lesser extent, by the FDIC. In addition, as a large provider of consumer financial services, TB is subject to regulation, supervision, enforcement and examination by the CFPB. Almost every area of the operations and financial condition of TB is subject to extensive regulation and supervision and to various requirements and restrictions under federal and state law including loans, reserves, investments, issuance of securities, establishment of branches, capital adequacy, liquidity, earnings, dividends, management practices and the provision of services. TB is subject to supervision, examination, enforcement and reporting requirements under the Federal Reserve Act, the FDI Act, regulations of the FRB and certain of the requirements imposed by the Dodd-Frank Act. Trustmark and TB are also subject to a wide range of consumer protection laws and regulations.

------

*Restrictions on Lending, Insider Transactions and Affiliate Transactions*

TB is limited by state and/or federal law in the amounts it may lend to one borrower, to insiders and to affiliates. In addition, the FDI Act imposes restrictions on TB's purchases of assets from insiders.

Mississippi law generally limits a Mississippi state-chartered bank's total extensions of credit to any one person or company to 20% of the bank's aggregate unimpaired capital and surplus, and limits total extensions of credit to a single director or executive officer to 15% of unimpaired capital and surplus, or 20% when secured. Section 22 of the Federal Reserve Act, as implemented by the FRB's Regulation O, similarly limits extensions of credit by a bank to its executive officers, directors, principal shareholders and their related interests, and to similar individuals at the holding company or affiliates. In general, such extensions of credit (i) may not exceed certain dollar limitations, (ii) must be made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with third parties and (iii) must not involve more than the normal risk of repayment or present other unfavorable features.

Sections 23A and 23B of the Federal Reserve Act establish parameters for an insured bank to conduct "covered transactions" with its affiliates, generally (i) limiting the extent to which the bank or its subsidiaries may engage in "covered transactions" with any one affiliate to an amount equal to 10% of the bank's capital stock and surplus, and limiting the aggregate of all such transactions with all affiliates to an amount equal to 20% of the bank's capital stock and surplus, and (ii) requiring that all such transactions be on terms substantially the same, or at least as favorable, to the bank or subsidiary as those that would be provided to a non-affiliate. In addition, an insured bank's loans to affiliates must be fully collateralized. The term "covered transaction" includes the making of loans to the affiliate, purchase of assets from the affiliate, issuance of a guarantee on behalf of the affiliate and several other types of transactions.

*Payment of Dividends*

The principal source of Trustmark's cash revenue is dividends from TB. As a Mississippi state-chartered banking corporation, TB must obtain the approval of the MDBCF prior to declaring or paying a dividend on its common stock.

*Community Reinvestment Act*

The CRA requires an insured depository institution's appropriate federal banking regulator to evaluate the institution's record of meeting the credit needs of its entire community, including low- and moderate-income neighborhoods, and to consider this record in its evaluation of certain applications to banking regulators, such as an application for approval of a merger or the establishment of a branch. A rating of less than "Satisfactory" may provide a basis for denial of such an application. TB received a rating of "Outstanding" in its most recent CRA performance evaluation, which covered activities in the period from January 1, 2022 through December 31, 2023.

On October 24, 2023, the federal banking agencies released a final rule revising their framework for evaluating banks' records of community reinvestment under the CRA. On July 16, 2025, the agencies issued a notice of proposed rulemaking to rescind the October 2023 final rule and restore the CRA framework that existed prior to the October 2023 final rule. TB's most recent performance evaluation was conducted using the CRA framework that existed prior to the October 2023 final rule.

*Consumer Protection Laws*

TB is subject to a number of federal and state laws designed to protect customers and promote lending to various sectors of the economy and population. These consumer protection laws apply to a broad range of TB's activities and to various aspects of its business, and include laws relating to interest rates, fair lending, disclosures of credit terms and estimated transaction costs to consumer borrowers, debt collection practices, the use of and the provision of information to consumer reporting agencies and the prohibition of unfair, deceptive or abusive acts or practices in connection with the offer, sale or provision of consumer financial products and services. These laws include the Equal Credit Opportunity Act, the Fair Credit Reporting Act, the Truth in Lending Act, the Home Mortgage Disclosure Act, the Real Estate Settlement Procedures Act, the Fair Debt Collection Practices Act and their state law counterparts. At the federal level, most consumer financial protection laws are administered by the CFPB, which supervises TB. The CFPB also has authority to issue regulations and has proposed several rules that would restrict various fees that financial institutions can charge consumers, including credit card late fees, overdraft fees and certain insufficient funds (NSF) fees.

Violations of applicable consumer protection laws can result in significant potential liability, including actual damages, restitution and injunctive relief, from litigation brought by customers, state attorneys general and other plaintiffs, as well as enforcement actions by banking regulators and reputational harm.

Many states and local jurisdictions have consumer protection laws analogous, and in addition to, those listed above. While TB's activities are governed primarily by federal law, states may adopt their own consumer protection laws that exceed the requirements of

------

federal law. In addition, under the Dodd-Frank Act, state attorneys general are authorized to bring civil actions to enforce regulations prescribed by the CFPB or to secure other remedies.

*Financial Privacy Laws and Cybersecurity*

The Gramm-Leach-Bliley Financial Services Modernization Act of 1999 (GLB Act) imposed requirements related to the privacy of customer financial information. In accordance with the GLB Act, federal bank regulators adopted rules that limit the ability of banks and other financial institutions to disclose nonpublic information about consumers to nonaffiliated third parties. The GLB Act also requires disclosure of privacy policies to consumers and, in some circumstances, allows consumers to prevent disclosure of certain personal information to a nonaffiliated third party. The privacy provisions of the GLB Act affect how consumer information is transmitted through diversified financial companies and conveyed to outside vendors. Trustmark recognizes the need to comply with legal and regulatory requirements that affect its customers' privacy.

In addition, the federal banking agencies pay close attention to the cybersecurity practices of banks, and the agencies include review of an institution's information technology and its ability to thwart cyberattacks in their examinations. An institution's failure to have adequate cybersecurity safeguards in place can result in supervisory criticism, monetary penalties and/or reputational harm. Additionally, banking organizations are required to notify their primary federal regulator of significant computer security incidents within 36 hours of determining that such an incident has occurred.

On October 22, 2024, the CFPB released a final rule to implement Section 1033 of the Dodd-Frank Act. Under the final rule, a financial institution would be required, upon request, to make available to a consumer or third party authorized by the consumer certain information the institution has concerning a consumer financial product or service covered by the rule, such as a credit card or a deposit account. Industry organizations challenged the final rule in court. On July 29, 2025, the district court granted a motion by the CFPB to stay the proceedings while the CFPB conducts a rulemaking to revise the final rule substantially. On August 22, 2025, the CFPB issued an advance notice of proposed rulemaking to solicit comments and data on several issues as part of a reconsideration of the final rule. On October 29, 2025, the district court issued a preliminary injunction preventing the CFPB from enforcing the final rule until the CFPB has completed its reconsideration of the rule. Management is monitoring the status of the litigation and evaluating the impact of this rule.

*Debit Interchange Regulation*

The FRB has issued rules under the Electronic Fund Transfer Act (EFTA), as amended by the Dodd-Frank Act, to limit interchange fees that an issuer with $10.0 billion or more in assets, such as TB, may receive or charge for an electronic debit card transaction. Under the FRB's rules, the maximum permissible interchange fee that an issuer may receive for an electronic debit transaction is the sum of 21 cents per transaction and five basis points multiplied by the value of the transaction. In addition, the FRB's rules allow for an upward adjustment of no more than one cent to an issuer's debit card interchange fee if the issuer develops and implements policies and procedures reasonably designed to achieve the fraud-prevention standards set out in the rule.

In October 2023, the FRB proposed changes to its EFTA rules that would decrease the maximum interchange fees that an issuer may receive for an electronic debit transaction to the sum of 14.4 cents and four basis points multiplied by the value of the transaction and increase the fraud prevention adjustment to 1.3 cents. If finalized as proposed, the proposal could reduce interchange revenue for banks with $10 billion or more in assets, such as TB.

The FRB also has established rules governing routing and exclusivity that require debt card issuers to offer two unaffiliated networks for routing transactions on each debit or prepaid product.

***FDIC Deposit Insurance Assessments***

The deposits of TB are insured by the Deposit Insurance Fund (DIF), as administered by the FDIC, and, accordingly, are subject to deposit insurance assessments to maintain the DIF at minimum levels required by statute.

The FDIC uses a risk-based assessment system that imposes insurance premiums as determined by multiplying an insured bank's assessment base by its assessment rate. A bank's deposit insurance assessment base is generally equal to the bank's total assets minus its average tangible equity during the assessment period.

The FDIC determines a bank's assessment rate within a range of base assessment rates using a risk scorecard that takes into account the bank's financial ratios and supervisory rating (the CAMELS composite rating), among other factors. The CAMELS rating system is a supervisory rating system developed to classify a bank's overall condition by taking into account capital adequacy, assets, management capability, earnings, liquidity and sensitivity to market and interest rate risk. The methodology that the FDIC uses to calculate

------

assessment amounts is also based on the FDIC's designated reserve ratio, which is currently 2.0%. During the COVID-19 pandemic, the amount of total estimated insured deposits grew rapidly while the funds in the DIF grew at a normal rate, causing the DIF reserve ratio to fall below the statutory minimum of 1.35%. The FDIC adopted a restoration plan in September 2020, which it amended in June 2022, to restore the DIF reserve ratio to at least 1.35% by September 30, 2028. On October 18, 2022, the FDIC adopted a final rule to increase initial base deposit insurance assessment rates for insured depository institutions by 2 basis points, which began with the first quarterly assessment period of 2023 and will remain in effect unless and until the DIF reserve ratio meets or exceeds 2.00%.

In November 2023, the FDIC adopted a final rule to implement a special deposit insurance assessment for eight quarters starting with the first quarter of 2024, to recover losses to the DIF arising from the bank failures of Spring 2023. In December 2025, the FDIC updated its estimate of the DIF's losses and reduced the final assessment rate for the eighth collection quarter. The special assessment was not material to Trustmark's financial condition or results of operations.

The FDIC may terminate the deposit insurance of any insured depository institution, including the TB, if the FDIC determines after a hearing that the institution has engaged or is engaging in unsafe or unsound banking practices, is in an unsafe or unsound condition to continue operations or has violated any applicable law, regulation, order or any condition imposed by an agreement with the FDIC. The FDIC also may suspend deposit insurance temporarily during the hearing process for the permanent termination of insurance if the institution has no tangible capital.

In 2025, TB's expenses related to deposit insurance premiums totaled $15.7 million.

***TB Subsidiaries***

**ITEM 1A. RISK FACTORS**

Trustmark and its subsidiaries could be adversely impacted by various risks and uncertainties, which are difficult to predict. As a financial institution, Trustmark has significant exposure to market risks, including interest rate risk, liquidity risk and credit risk. This section includes a description of the risks, uncertainties and assumptions identified by Management that could, individually or in combination, materially affect Trustmark's financial condition and results of operations, as well as the value of Trustmark's financial instruments in general, and Trustmark common stock, in particular. Additional risks and uncertainties that Management currently deems immaterial or is unaware of may also impair Trustmark's financial condition and results of operations. This report is qualified in its entirety by the risk factors that are identified below.

**Risks Related to Trustmark's Business**

***Interest Rate Risks***

*Trustmark's largest source of revenue (net interest income) is subject to interest rate risk.*

Trustmark's profitability depends to a large extent on net interest income, which is the difference between income on interest-earning assets, such as loans and investment securities, and expense on interest-bearing liabilities, such as deposits and borrowings. Trustmark is exposed to interest rate risk in its core banking activities of lending and deposit taking, since assets and liabilities reprice at different times and by different amounts as interest rates change. Trustmark is unable to predict changes in market interest rates, which are affected by many factors beyond Trustmark's control, including inflation, recession, unemployment, money supply, domestic and international events and changes in the United States and other financial markets. For most of 2025, the FRB left the target federal funds rate unchanged at a range of 4.25% to 4.50% and maintained the rate it pays on reserves at 4.40%. However, beginning with the

------

September 2025 meeting of the FRB's Federal Open Market Committee, the FRB noted increases in unemployment and inflation shifting the balance of risks to achieving its goals. As a result, the FRB decreased the target federal funds rate and the rate it pays on reserves multiple times during the fourth quarter of 2025, lowering the target federal funds rate to a range of 3.50% to 3.75% and the rate it pays on reserves to 3.65% as of December 2025. Prior period rate increases increased the competitive pressures on the deposit cost of funds. While rate cuts potentially reduced those competitive pressures, they increased pressure on Trustmark's net interest margin, a key component to its financial results. It is not possible to predict the direction, pace or magnitude of further changes, if any, in interest rates, or the impact any such rate changes will have on Trustmark's results of operations.

Financial simulation models are the primary tools used by Trustmark to measure interest rate exposure. Using a wide range of scenarios, Management is provided with extensive information on the potential impact to 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. Trustmark's simulation model using static balances at December 31, 2025 estimated that in the event of a hypothetical 200 basis point increase in interest rates, net interest income may increase 3.1%, while a hypothetical 100 basis point increase in interest rates may increase net interest income 1.5%. In the event of a hypothetical 100 basis point decrease in interest rates using static balances at December 31, 2025, it is estimated net interest income may decrease 2.1%, while a hypothetical 200 basis point decrease in interest rates may decrease net interest income 4.8%.

Net interest income is Trustmark's largest revenue source, and it is important to discuss how Trustmark's interest rate risk may be influenced by the various factors shown below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•In general, for a given change in interest rates, the amount of the change in value (positive or negative) is larger for assets and liabilities with longer remaining maturities. The shape of the yield curve may affect new loan yields, funding costs and investment income differently.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The remaining maturity of various assets or liabilities may shorten or lengthen as payment behavior changes in response to changes in interest rates. For example, if interest rates decline sharply, fixed-rate loans may pre-pay, or pay down, faster than anticipated, thus reducing future cash flows and interest income. Conversely, if interest rates increase, depositors may cash in their certificates of deposit prior to term (notwithstanding any applicable early withdrawal penalties) or otherwise reduce their deposits to pursue higher yielding investment alternatives. Repricing frequencies and maturity profiles for assets and liabilities may occur at different times. For example, in a falling rate environment, if assets reprice faster than liabilities, there will be an initial decline in earnings. Moreover, if assets and liabilities reprice at the same time, they may not be by the same increment. For instance, if the federal funds rate increased 50 basis points, rates on demand deposits may rise by 10 basis points, whereas rates on prime-based loans will instantly rise 50 basis points.

Financial instruments do not respond in a parallel fashion to rising or falling interest rates. This causes asymmetry in the magnitude of changes in net interest income, net economic value and investment income resulting from the hypothetical increases and decreases in interest rates. Therefore, Management monitors interest rate risk and adjusts Trustmark's investment, funding and hedging strategies to mitigate adverse effects of interest rate shifts on Trustmark's balance sheet.

Trustmark utilizes derivative contracts to hedge the mortgage servicing rights (MSR) in order to offset changes in fair value resulting from changes in interest rate environments. In spite of Trustmark's due diligence in regard to these hedging strategies, significant risks are involved that, if realized, may prove such strategies to be ineffective, which could adversely affect Trustmark's financial condition or results of operations. Risks associated with these strategies include the risk that counterparties in any such derivative and other hedging transactions may not perform; the risk that these hedging strategies rely on Management's assumptions and projections regarding these assets and general market factors, including prepayment risk, basis risk, market volatility and changes in the shape of the yield curve, and that these assumptions and projections may prove to be incorrect; the risk that these hedging strategies do not adequately mitigate the impact of changes in interest rates, prepayment speeds or other forecasted inputs to the hedging model; and the risk that the models used to forecast the effectiveness of hedging instruments may project expectations that differ from actual results. In addition, increased regulation of the derivative markets may increase the cost to Trustmark to implement and maintain an effective hedging strategy.

Trustmark closely monitors the sensitivity of net interest income and investment income to changes in interest rates and attempts to limit the variability of net interest income as interest rates change. Trustmark makes use of both on- and off-balance sheet financial instruments to mitigate exposure to interest rate risk.

------

***Credit and Lending Risks***

*Trustmark is subject to lending risk, which could impact the adequacy of the allowance for credit losses and results of operations.*

There are inherent risks associated with Trustmark's lending activities. If trends in the housing and real estate markets were to decline appreciably, Trustmark may experience higher than normal delinquencies and credit losses. Moreover, if the United States economy were to enter into a recession, Management expects that this scenario could severely affect economic conditions in Trustmark's market areas and that Trustmark could experience significantly higher delinquencies and credit losses.

In addition, bank regulatory agencies periodically review Trustmark's allowance for credit losses and may require an increase in the provision for credit losses or the recognition of further charge-offs, based on judgments different from those of Management. As a result, Trustmark may elect, or be required, to make further increases in its provision for credit losses in the future, particularly if economic conditions deteriorate.

Trustmark may also rely on information furnished by or on behalf of customers and counterparties in deciding whether to extend credit or enter into other transactions. This information could include financial statements, credit reports, business plans, and other information. Trustmark may also rely on representations of those customers, counterparties or other third parties, such as independent auditors, as to the accuracy and completeness of that information. Reliance on inaccurate or misleading financial statements, credit reports or other information could have a material adverse impact on Trustmark's business, financial condition and results of operations.

*Trustmark is subject to environmental liability risk associated with lending activities.*

A significant portion of Trustmark's loan portfolio is secured by real property. During the ordinary course of business, Trustmark forecloses on and takes title to properties securing certain loans. In doing so, there is a risk that hazardous or toxic substances could be found on these properties. If hazardous or toxic substances are found, Trustmark may be liable for remediation costs, as well as for personal injury and property damage, civil fines and criminal penalties regardless of when the hazardous conditions or toxic substances first affected any particular property. Environmental laws may require Trustmark to incur substantial expenses and may materially reduce the affected property's value or limit Trustmark's ability to use or ability to sell the affected property or to repay the indebtedness secured by the property. In addition, future laws or more stringent interpretations or enforcement policies with respect to existing laws may increase Trustmark's exposure to environmental liability. Environmental reviews of nonresidential real estate before initiating foreclosure actions may not be sufficient to detect all potential environmental hazards. The remediation costs and any other financial liabilities associated with an environmental hazard could have a material adverse effect on Trustmark's business, financial condition and results of operations.

*Declines in asset values may result in credit losses and adversely affect the value of Trustmark's investments.*

Trustmark maintains an investment portfolio that includes, among other asset classes, obligations of states and municipalities, agency debt securities and agency mortgage-related securities. The market value of investments in Trustmark's investment portfolio may be affected by factors other than interest rates or the underlying performance of the issuer of the securities, such as ratings downgrades, adverse changes in the business climate and a lack of pricing information or liquidity in the secondary market for certain investment securities. In addition, government involvement or intervention in the financial markets or the lack thereof or market perceptions regarding the existence or absence of such activities could affect the market and the market prices for these securities.

On a quarterly basis, Trustmark evaluates investments and other assets for expected credit losses. At December 31, 2025, gross unrealized losses on securities for which an allowance for credit losses has not been recorded totaled $14.5 million. Trustmark may be required to record credit loss expense if these investments suffer a decline in value that is the result of a credit loss. If Trustmark determines that a credit loss exists, the credit portion of the allowance would be measured using a discounted cash flow (DCF) analysis using the effective interest rate as of the security's purchase date. The amount of credit loss Trustmark may record is limited to the amount by which the amortized cost exceeds the fair value, which could have a material adverse effect on results of operations in the period in which a credit loss, if any, occurs.

***Liquidity Risk***

*Trustmark is subject to liquidity risk, which could disrupt its ability to meet its financial obligations.*

Liquidity refers to Trustmark's 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. Liquidity risk arises whenever the maturities of financial instruments included in assets and liabilities differ or when assets cannot be liquidated at fair market value as needed. Trustmark obtains funding through deposits and various short-term and long-term wholesale borrowings, including federal funds purchased and securities sold under repurchase agreements, the Federal Reserve Discount Window

------

(Discount Window) and Federal Home Loan Bank (FHLB) advances. Any significant restriction or disruption of Trustmark's ability to obtain funding from these or other sources could have a negative effect on Trustmark's ability to satisfy its current and future financial obligations, which could materially affect Trustmark's financial condition or results of operations.

In addition to the risk that one or more of the funding sources may become constrained due to market conditions unrelated to Trustmark, there is the risk that Trustmark's credit profile may decline such that one or more of these funding sources becomes partially or wholly unavailable to Trustmark.

Trustmark attempts to quantify such credit event risk by modeling bank specific and systemic scenarios that estimate the liquidity impact. Trustmark estimates such impact by attempting to measure the effect on available unsecured lines of credit, available capacity from secured borrowing sources and securitizable assets. To mitigate such risk, Trustmark maintains available lines of credit with the FRBA and the FHLB of Dallas that are secured by loans and investment securities. Management continuously monitors Trustmark's liquidity position for compliance with internal policies.

***External and Market-Related Risks***

*Trustmark's business may be adversely affected by conditions in the financial markets and economic conditions in general.*

Economic activity improved slightly during 2025, but was characterized by mixed signals, notably, strong equity market performance, continued consumer spending and FRB rate cuts, but also a softening labor market and persistent inflationary pressures, driven partly by new tariffs. United States stocks performed strongly during the second half of 2025, supported by optimistic sentiment around lower interest rates, better-than-expected corporate earnings and strong performance in the technology and AI sectors. However, economic concerns remain as a result of the cumulative weight of uncertainty regarding the potential economic impact of geopolitical developments, such as the conflicts in Ukraine and the Middle East, the current United States presidential administration's policies, inflationary and broader pricing pressures and other economic and industry volatility. Concerns surrounding the 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.

Strategic risk, including threats to business models from increasing pressures on net interest margins and modest economic growth, remains high. Management's ability to plan, prioritize and allocate resources in this environment will be critical to Trustmark's ability to sustain earnings that will attract capital. Because of the complexities presented by current economic conditions, Management will continue to be challenged in identifying alternative sources of revenue, prudently diversifying assets, liabilities and revenue and effectively managing the costs of compliance.

Trustmark is intently monitoring the impact of tariffs and other administrative policies on its customer base, interest rates and credit-related issues. Economic uncertainty or disruptions in the marketplace as a result of such policies could reduce loan demand or increase loan nonperformance. It is not possible to predict the timing or magnitude of changes to policies by the current United States presidential administration, if any, or the impact any such policy changes could have on Trustmark's customer base, credit quality or results of operations.

Trustmark does not assume that current uncertain conditions in the economy will improve significantly in the near future. A weakened economy could affect Trustmark in a variety of substantial and unpredictable ways. In particular, Trustmark may face the following risks in connection with these events:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Market developments and the resulting economic pressure on consumers may affect consumer confidence levels and may cause increases in delinquencies and default rates, which, among other effects, could further affect Trustmark's charge-offs and provision for credit losses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Loan performance could experience a significantly extended deterioration or loan default levels could accelerate, foreclosure activity could significantly increase, or Trustmark's assets (including loans and investment securities) could materially decline in value, any one of which, or any combination of more than one of which, could have a material adverse effect on Trustmark's financial condition or results of operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Management's ability to measure the fair value of Trustmark's assets could be adversely affected by market disruptions that could make valuation of assets more difficult and subjective. If Management determines that a significant portion of its assets have values that are significantly below their recorded carrying value, Trustmark could recognize a material charge

------

to earnings in the quarter during which such determination was made, Trustmark's capital ratios would be adversely affected by any such charge, and a rating agency might downgrade Trustmark's credit rating or put Trustmark on credit watch.

While the banking industry has stabilized since the disruptions associated with bank failures in Spring 2023, there remains heightened awareness around liquidity, uninsured deposits, deposit composition, unrecognized investment losses and capital among counterparties, customers and regulators. It is difficult to predict the extent to which these conditions will persist or whether recent progress in the economic recovery will instead shift to the potential for further decline. If the economy does weaken in the future, it is uncertain how Trustmark's business would be affected and whether Trustmark would be able to successfully mitigate any such effects on its business. Accordingly, these factors in the United States (and, indirectly, global) economy could have a material adverse effect on Trustmark's financial condition and results of operations.

*Trustmark operates in a highly competitive financial services industry.*

Trustmark faces substantial competition in all areas of its operations from a variety of different competitors, many of which are larger and may have greater financial resources. Such competitors primarily include banks, as well as community banks operating nationwide and regionally within the various markets in which Trustmark operates. Trustmark also faces competition from many other types of financial institutions, including savings and loans, credit unions, finance companies, brokerage firms, factoring companies and other financial intermediaries. Additionally, fintech developments, such as blockchain and other distributed ledger technologies, have the potential to disrupt the financial industry and change the way banks do business. The financial services industry could become even more competitive as a result of legislative, regulatory and technological changes and continued consolidation.

Some of Trustmark's competitors have fewer regulatory constraints and may have lower cost structures. Additionally, due to their size, many of Trustmark's larger competitors may be able to achieve economies of scale and, as a result, may offer a broader range of products and services as well as better pricing for those products and services than Trustmark.

Trustmark's ability to compete successfully depends on a number of factors, including: the ability to develop, maintain and build upon long-term customer relationships based on top quality service, high ethical standards and safe, sound assets; the ability to continue to expand Trustmark's market position through organic growth and acquisitions; the scope, relevance and pricing of products and services offered to meet customer needs and demands; the rate at which Trustmark introduces new products and services relative to its competitors; and industry and general economic trends. Failure to perform in any of these areas could significantly weaken Trustmark's competitive position, which could adversely affect Trustmark's financial condition or results of operations.

*The soundness of other financial institutions could adversely affect Trustmark.*

Financial services institutions are interrelated as a result of trading, clearing, counterparty or other relationships. As a result, defaults by, or questions or rumors about, one or more financial services institutions or the financial services industry in general, could lead to market-wide liquidity problems, which could, in turn, lead to defaults or losses by Trustmark and by other institutions. Trustmark has exposure to many different industries and counterparties, and routinely executes transactions with counterparties in the financial services industry, including commercial banks, brokers and dealers, investment banks, mutual funds, and other institutional clients. Many of these transactions expose Trustmark to credit risk in the event of default of its counterparty or client. In addition, Trustmark's credit risk may be exacerbated when the collateral it holds cannot be realized upon or is liquidated at prices not sufficient to recover the full amount of the credit or derivative exposure owed to Trustmark. Losses related to these credit risks could materially and adversely affect Trustmark's results of operations.

***Compliance and Regulatory Risks***

*Trustmark is subject to extensive government regulation and supervision and possible enforcement and other legal actions.*

Trustmark, primarily through TB and certain nonbank subsidiaries, is subject to extensive federal and state regulation and supervision, which vests a significant amount of discretion in the various regulatory authorities. Banking regulations are primarily intended to protect depositors' funds, federal deposit insurance funds and the banking system as a whole, not security holders. These regulations and supervisory guidance affect Trustmark's lending practices, capital structure, investment practices, dividend policy and growth, among other things. Congress and federal and state regulatory agencies continually review banking laws, regulations and policies for possible changes. Changes to statutes, regulations or regulatory policies or supervisory guidance, including changes in interpretation or implementation or statutes, regulations, policies and supervisory guidance, could affect Trustmark in substantial and unpredictable ways. Such changes could subject Trustmark to additional costs, limit the types of financial services and products Trustmark may offer and/or increase the ability of nonbanks to offer competing financial services and products, among other things. Failure to comply with laws, regulations, policies or supervisory guidance could result in enforcement and other legal actions by Federal or state authorities, including criminal and civil penalties, the loss of FDIC insurance, the revocation of a banking charter, civil money penalties, other sanctions by

------

regulatory agencies and/or reputational damage. In this regard, government authorities, including bank regulatory agencies, have the authority to pursue enforcement agendas with respect to compliance and other legal matters involving financial activities, which heightens the risks associated with actual and perceived compliance failures. Any of the foregoing could have a material adverse effect on Trustmark's financial condition or results of operations.

*Trustmark is subject to numerous laws designed to protect consumers, including fair lending laws, and failure to comply with these laws could lead to a wide variety of sanctions.*

The Equal Credit Opportunity Act, the Fair Housing Act and other fair lending laws and regulations impose nondiscriminatory lending requirements on financial institutions. The DOJ and other federal agencies are responsible for enforcing these laws and regulations. A successful regulatory challenge to an institution's performance under fair lending laws and regulations could result in a wide variety of direct or indirect negative consequences, including damages and civil money penalties, injunctive relief, restrictions on mergers and acquisitions activity, restrictions on geographic expansion and restrictions on entering new business lines. Private parties may also have the ability to challenge an institution's performance under fair lending laws in private class action litigation. Such actions could have a material adverse effect on Trustmark's business, financial condition or results of operations.

In addition, financial institutions face scrutiny on actions and policies that are deemed to adversely impact consumers under the Dodd-Frank Act's prohibition against unfair, deceptive or abusive acts and practices and Section 5 of the Federal Trade Commission Act's prohibition against unfair or deceptive acts and practices. Bank regulators and the CFPB are responsible for enforcing these prohibitions against banking organizations. These prohibitions have been applied to prohibit perceived customer abuse in connection with a range of products, services, and practices, including account openings and fees charged where inadequate or no services are rendered for which charges were imposed, as well as other instances where consumers may have been misled through bank disclosures. In addition, the enforcement priorities of the agencies enforcing consumer protection laws have evolved over time and may continue to do so.

*Failure by Trustmark to perform satisfactorily on its CRA evaluations could make it more difficult for Trustmark's business to grow.*

The performance of a bank under the CRA in meeting the credit needs of its community is a factor that must be taken into consideration when the federal banking agencies evaluate applications related to mergers and acquisitions, as well as branch opening and relocations. As of its last examination, TB received a CRA rating of "Outstanding," which represented an improvement from its previous CRA rating of "Needs to Improve." TB's failure to maintain at least a "Satisfactory" CRA rating in the future could adversely affect its ability to complete the acquisition of another financial institution or open a new branch. If TB were to receive an overall CRA rating of less than "Satisfactory" in the future, the FRB would not re-evaluate the CRA rating until TB's next CRA examination, which may not occur for several years. It is possible that a low CRA rating would not improve in the future.

*Trustmark is subject to stringent capital requirements.*

Under the regulatory capital rules of the FRB, OCC, and FDIC that implement a set of capital requirements issued by the Basel Committee on Banking Supervision known as Basel III, Trustmark and TB are required to maintain a common equity Tier 1 capital to risk-weighted assets ratio of at least 7.0% (a minimum of 4.5% plus a capital conservation buffer of 2.5%), a Tier 1 capital to risk-weighted assets ratio of at least 8.5% (a minimum of 6.0% plus a capital conservation buffer of 2.5%), a total capital to risk-weighted assets ratio of at least 10.5% (a minimum of 8.0% plus a capital conservation buffer of 2.5%) and a leverage ratio of Tier 1 capital to total consolidated assets of at least 4.0%. In addition, for TB to be "well-capitalized" under the banking agencies' prompt corrective action framework, it must have a common equity Tier 1 capital ratio of at least 6.5%, a Tier 1 capital ratio of at least 8.0%, a total capital ratio of at least 10.0% and a leverage ratio of at least 5.0%, and must not be subject to any written agreement, order or capital directive, or prompt corrective action directive issued by its primary federal regulator to meet and maintain a specific capital level for any capital measure.

The capital rules also include stringent criteria for capital instruments to qualify as Tier 1 or Tier 2 capital. For instance, the rules effectively disallow newly issued trust preferred securities to be a component of a holding company's Tier 1 capital. Trustmark will continue to count $60.0 million in outstanding trust preferred securities issued by the Trust as Tier 1 capital up to the regulatory limit, as permitted by a grandfather provision in the capital rules, but this grandfather provision may cease to apply if Trustmark consummates an acquisition of a depository institution holding company.

Financial Accounting Standards Board (FASB) Accounting Standard Codification (ASC) Topic 326, "*Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments*," requires Trustmark to recognize all expected credit losses over the life of a loan based on historical experience, current conditions and reasonable and supportable forecasts. FASB ASC Topic 326 generally results in earlier recognition of credit losses, which would increase reserves and decrease capital. Additionally, the allowance for credit losses model could be materially impacted by changes in current and forecasted macroeconomic conditions. It is not possible to predict the timing or magnitude of changes in macroeconomic conditions or the impact such changes could have on Trustmark's

------

allowance for credit losses; however, material changes in the allowance for credit losses could have a material impact on Trustmark's reserves and capital.

The regulatory capital rules applicable to Trustmark and TB may continue to evolve as a result of new requirements established by the Basel Committee on Banking Supervision or legislative, regulatory or accounting changes in the United States. Management cannot predict the effect that any changes to current capital requirements would have on Trustmark and TB.

*Trustmark's use of third-party service providers and Trustmark's other ongoing third-party business relationships are subject to increasing regulatory requirements and attention.*

Trustmark regularly uses third-party service providers and subcontractors as part of its business. Trustmark also has substantial ongoing business relationships with partners and other third-parties and relies on certain third-parties to provide products and services necessary to maintain day-to-day operations. These types of third-party relationships are subject to increasingly demanding regulatory requirements and attention by regulators, including the FRB, OCC, CFPB and FDIC. Under interagency regulatory guidance issued in 2023, Trustmark is required to apply stringent due diligence, conduct ongoing monitoring and maintain effective control over third-party service providers and subcontractors and other ongoing third-party business relationships. These regulatory expectations may continue to evolve and become more rigorous over time. Trustmark expects that the regulators will hold Trustmark responsible for deficiencies in its oversight and control of its third-party relationships and in the performance of the parties with which Trustmark has these relationships. Trustmark maintains a system of policies and procedures designed to ensure adequate due diligence is performed and to monitor vendor risks. While Trustmark believes these policies and procedures effectively mitigate risk, if the regulators conclude that Trustmark has not exercised adequate oversight and control over third-party service providers and subcontractors or other ongoing third-party business relationships or that such third-parties have not performed appropriately, Trustmark could be subject to enforcement actions, including civil monetary penalties or other administrative or judicial penalties or fines as well as requirements for customer remediation.

*Trustmark's ability to declare and pay dividends is subject to restriction by various laws and regulations and other factors.*

Trustmark is a separate and distinct legal entity from TB, and receives substantially all of its cash stream from dividends from TB. These dividends are the principal source of funds to pay dividends on Trustmark's common stock and interest on its debt. Various federal and state laws and regulations limit the amount of dividends that TB may pay to Trustmark. In the event TB is unable to declare dividends, or is limited in the amount of any dividend it may be able to declare, Trustmark may not be able to declare dividends on its common stock or meet other financial obligations. Any inability to receive dividends from TB could have a material adverse effect on Trustmark's business, financial condition and results of operations. The information under the section captioned "Supervision and Regulation" included in Part I. Item 1. – Business in this report provides further discussion about the restrictions governing TB's ability to transfer funds to Trustmark.

***Operational Risks***

*There may be risks resulting from the extensive use of models in Trustmark's business.*

Trustmark relies on statistical and quantitative models to measure risks and to estimate certain financial values. Models may be used in such processes as determining the pricing of various products, assessing potential acquisition opportunities, developing presentations made to market analysts and others, creating loans and extending credit, measuring interest rate and other market risks, predicting losses, assessing capital adequacy, calculating regulatory capital levels and estimating the fair value of financial instruments and balance sheet items. These models reflect assumptions that may not be accurate, particularly in times of market stress or other unforeseen circumstances. Even if these assumptions are adequate, the models may prove to be inadequate or inaccurate because of other flaws in their design or their implementation. If models for determining interest rate risk and asset-liability management are inadequate, Trustmark may incur increased or unexpected losses upon changes in market interest rates or other market measures. If models for determining expected credit losses are inadequate, the allowance for credit losses may not be sufficient to support future charge-offs. If models to measure the fair value of financial instruments are inadequate, the fair value of such financial instruments may fluctuate unexpectedly or may not accurately reflect what Trustmark could realize upon sale or settlement of such financial instruments. Any such failure in the analytical or forecasting models could have a material adverse effect on Trustmark's financial condition or results of operations.

Also, information Trustmark provides to its regulators based on poorly designed or implemented models could be inaccurate or misleading. Certain decisions that the regulators make, including those related to capital distributions and dividends to Trustmark's shareholders, could be adversely affected due to the regulator's perception that the quality of Trustmark's models used to generate the relevant information is insufficient.

*Trustmark could be required to write down goodwill and other intangible assets.*

If Trustmark consummates an acquisition, a portion of the purchase price would generally be allocated to goodwill and other identifiable intangible assets. The amount of the purchase price that is allocated to goodwill and other intangible assets is determined by the excess of the purchase price over the net identifiable assets acquired. At December 31, 2025, goodwill was $334.6 million. Trustmark's other identifiable intangible assets, net were fully amortized as of December 31, 2025. Under current accounting standards, if Trustmark determines goodwill or other intangible assets are impaired, Trustmark would be required to write down the carrying value of these assets. Trustmark's annual goodwill impairment evaluation performed during the fourth quarter of 2025 indicated no impairment of goodwill for any reporting segment. Management cannot provide assurance, however, that Trustmark will not be required to take an impairment charge in the future. Any impairment charge would have an adverse effect on Trustmark's shareholders' equity and financial condition and could cause a decline in Trustmark's stock price.

*Trustmark holds other real estate and may acquire and hold significant additional amounts, which could lead to increased operating expenses and vulnerability to additional declines in real property values.*

As business necessitates, Trustmark forecloses on and takes title to real estate serving as collateral for loans. At December 31, 2025, Trustmark held $7.0 million of other real estate. The amount of other real estate held by Trustmark may increase in the future as a result of, among other things, business combinations, increased uncertainties in the housing market or increased levels of credit stress in residential real estate loan portfolios. Increased other real estate balances could lead to greater expenses as Trustmark incurs costs to manage, maintain and dispose of real properties as well as to remediate any environmental cleanup costs incurred in connection with any contamination discovered on real property on which Trustmark has foreclosed and to which Trustmark has taken title. As a result, Trustmark's earnings could be negatively affected by various expenses associated with other real estate owned, including personnel costs, insurance and taxes, completion and repair costs, valuation adjustments and other expenses associated with real property ownership, as well as by the funding costs associated with other real estate assets. The expenses associated with holding a significant amount of other real estate could have a material adverse effect on Trustmark's financial condition or results of operations.

*If Trustmark is required to repurchase a significant number of mortgage loans that it had previously sold, such repurchases could negatively affect earnings.*

One of Trustmark's primary business operations is mortgage banking, under which residential mortgage loans are sold in the secondary market under agreements that contain representations and warranties related to, among other things, the origination and characteristics of the mortgage loans. Trustmark may be required to either repurchase the outstanding principal balance of a loan or make the purchaser whole for the anticipated 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 the Federal National Mortgage Association (FNMA) and the Federal Home Loan Mortgage Corporation (FHLMC) on or after January 1, 2013 are subject to the Representations and Warranties Framework, which provides that FNMA and FHLMC will not exercise their remedies, including a putback request, for breaches of certain selling representations and warranties if the mortgage loans satisfy certain criteria, such as payment history or quality control review.

*Changes in retail distribution strategies and consumer behavior may adversely impact Trustmark's investments in premises, equipment, technology and other assets and may lead to increased expenditures to change its retail distribution channel.*

Trustmark has significant investments in bank premises and equipment for its branch network. Advances in technology such as ecommerce, telephone, internet and mobile banking, and in-branch self-service technologies including interactive teller machines (ITMs) and other equipment, as well as an increasing customer preference for these other methods of accessing Trustmark's products and services, could decrease the value of its branch network, technology, or other retail distribution physical assets and may cause Trustmark to change its retail distribution strategy, close and/or sell certain branches or parcels of land held for development and restructure or reduce its remaining branches and work force. These actions could lead to losses on these assets or could adversely impact the carrying value of any long-lived assets and may lead to increased expenditures to renovate, reconfigure or close a number of Trustmark's remaining branches or to otherwise reform its retail distribution channel.

*Trustmark may experience disruptions of its operating systems or breaches in its information system security.*

Trustmark is dependent upon communications and information systems to conduct business as such systems are used to manage virtually all aspects of Trustmark's business. Trustmark's operations rely on the secure processing, storage and transmission of confidential and other information within its computer systems and networks. Any failure, interruption or breach in security of these systems could result

------

in significant disruption to Trustmark's operations. Trustmark has taken protective measures, which are continuously monitored and modified as warranted; however, Trustmark's computer systems, software and networks may fail to operate properly or become disabled or damaged as a result of a number of factors, including events that are wholly or partially beyond Trustmark's control. There could be sudden increases in customer transaction volume; electrical, telecommunications or other major physical infrastructure outages; natural disasters; and events arising from local or larger scale political or social matters, including terrorist acts.

Further, Trustmark's operational and security systems and infrastructure may be vulnerable to breaches and cybersecurity-related incidents including, but not limited to, attempts to access information, including customer and company information, malicious code, computer viruses and denial of service attacks that could result in unauthorized access, theft, misuse, loss, release or destruction of data (including confidential customer information), account takeovers, unavailability of service or other events. These types of threats may derive from human error, fraud or malice on the part of external or internal parties, or may result from accidental technological failure. If one or more of these events were to occur, Trustmark's or its customers' confidential and other information would be jeopardized, or such an event could cause interruptions or malfunctions in Trustmark's or its customers' or counterparties' operations. Any failures related to upgrades and maintenance of Trustmark's technology and information systems could further increase its information and system security risk. Trustmark's increased use of cloud and other technologies, such as remote work technologies, also increases its risk of being subject to a cyber-attack. The risk of a security breach or disruption, particularly through cyber-attack or cyber intrusion, has increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. Trustmark may be required to expend significant additional resources to modify its protective measures or to investigate and remediate vulnerabilities or other exposures in its computer systems and networks, and Trustmark may be subject to litigation and financial losses that are either not insured against or not fully covered through any insurance maintained by Trustmark. Any such losses, which may be difficult to detect, could adversely affect Trustmark's financial condition or results of operations. In addition, the occurrence of such a loss could expose Trustmark to reputational risk, the loss of customer business and additional regulatory scrutiny.

Security breaches in Trustmark's internet and mobile banking activities (*myTrustmark*<sup>®</sup>) could further expose Trustmark to possible liability and reputational risk. Any compromise in security could deter customers from using Trustmark's internet and mobile banking services that involve the transmission of confidential information. Trustmark relies on standard internet security systems to provide the security and authentication necessary to effect secure transmission of data. However, these precautions may not protect Trustmark's systems from compromise or breaches of security, which could result in significant legal liability and significant damage to Trustmark's reputation and business.

Trustmark relies upon certain third-party vendors to provide products and services necessary to maintain day-to-day operations. Accordingly, Trustmark's operations are exposed to the risk that these vendors might not perform in accordance with applicable contractual arrangements or service level agreements or that the security of the third-party vendors' computer systems, software and networks may be vulnerable to compromises that could impact information system security. Trustmark maintains a system of policies and procedures designed to monitor vendor risks. While Trustmark believes these policies and procedures effectively mitigate risk, the failure of an external vendor to perform in accordance with applicable contractual arrangements or service level agreements or any compromise in the security of an external vendor's information systems could be disruptive to Trustmark's operations, which could have a material adverse effect on its financial condition or results of operations.

As of the date of this Annual Report on Form 10-K, Trustmark has seen no material adverse impact on its business or operations from cyber-attacks or events. Trustmark's customers, employees and third parties that it does business with have been, and will continue to be, targeted by parties using fraudulent e-mails and other communications in attempts to misappropriate passwords, bank account information or other personal information or to introduce viruses or other malware programs to its information systems, the information systems of its merchants or third-party service providers and/or its customers' personal devices, which are beyond Trustmark's security control systems. Though Trustmark endeavors to mitigate these threats through product improvements, use of encryption and authentication technology and customer and employee education, such cyber-attacks against Trustmark, its merchants, third-party service providers and customers remain a serious issue and have been successful in the past.

Although Trustmark makes significant efforts to maintain the security and integrity of its information systems and has implemented various measures to manage the risks of a security breach or disruption, there can be no assurance that its security efforts and measures will be effective or that attempted security breaches or disruptions would not be successful or damaging. Even well protected information, networks, systems and facilities remain potentially vulnerable to attempted security breaches or disruptions because the techniques used in such attempts are constantly evolving and generally are not recognized until launched against a target, and in some cases are designed not to be detected and, in fact, may not be detected. Accordingly, Trustmark may be unable to anticipate these techniques or to implement adequate security barriers or other preventative measures, and thus it is virtually impossible for Trustmark to entirely mitigate this risk. Furthermore, in the event of a cyber-attack, Trustmark may be delayed in identifying or responding to the attack, which could increase the negative impact of the cyber-attack on its business, financial condition and results of operations. A security breach or other significant disruption of Trustmark's information systems or those related to its customers, merchants or third-party vendors, including as a result of cyber-attacks, could (i) disrupt the proper functioning of its networks and systems and therefore

------

its operations and/or those of its customers; (ii) result in the unauthorized access to, and destruction, loss, theft, misappropriation or release of confidential, sensitive or otherwise valuable information of Trustmark or its customers; (iii) result in a violation of applicable privacy, data breach and other laws, subjecting Trustmark to additional regulatory scrutiny and exposing it to civil litigation, enforcement actions, governmental fines and possible financial liability; (iv) require significant management attention and resources to remedy the damages that result; or (v) harm Trustmark's reputation or cause a decrease in the number of customers that choose to do business with Trustmark. The occurrence of any of the foregoing could have a material adverse effect on Trustmark's business, financial condition and results of operations.

*Trustmark must utilize new technologies to deliver its products and services, which could require significant resources and expose Trustmark to additional risks, including cyber-security risks.*

In order to deliver new products and services and to improve the productivity of existing products and services, the banking industry relies on rapidly evolving technologies. Trustmark continues to invest in technology to facilitate the ability of its customers to engage in financial transactions, and otherwise enhance the customer experience with respect to its products and services. Trustmark's ability to effectively utilize new technologies to address customer needs and create operating efficiencies could materially affect future prospects. Management cannot provide any assurances that Trustmark will be successful in utilizing such new technologies. Incorporation of new products and services, such as internet and mobile banking services, may require significant resources and expose Trustmark to additional risks, including cyber-security risks.

*Trustmark's controls and procedures may fail or be circumvented.*

Trustmark's internal controls, disclosure controls and procedures, and corporate governance policies and procedures are based in part on assumptions, and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Any failure or circumvention of Trustmark's controls and procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on Trustmark's business, financial condition and results of operations.

*Trustmark may be subject to increased claims and litigation, which could result in legal liability and reputational damage.*

Trustmark has been named from time to time as a defendant in litigation relating to its businesses and activities. Litigation may include claims for substantial compensatory or punitive damages or claims for indeterminate amounts of damages.

In recent years, a number of judicial decisions have upheld the right of borrowers to sue lending institutions on the basis of various evolving legal theories, collectively termed "lender liability." Generally, lender liability is founded on the premise that a lender has either violated a duty, whether implied or contractual, of good faith and fair dealing owed to the borrower or has assumed a degree of control over the borrower resulting in the creation of a fiduciary duty owed to the borrower or its other creditors or shareholders. Substantial legal liability against Trustmark, including its subsidiaries, could materially adversely affect Trustmark's business, financial condition or results of operations, or cause significant harm to its reputation.

*Damage to Trustmark's reputation could have a significant negative impact on Trustmark's business.*

Trustmark's ability to attract and retain customers, clients, investors, and highly-skilled management and employees is affected by its reputation. Significant harm to Trustmark's reputation can also arise from other sources, including employee misconduct, actual or perceived unethical or illegal behavior, litigation or regulatory outcomes, failing to deliver minimum or required standards of service and quality, compliance failures, disclosure of confidential information, significant or numerous failures, interruptions or breaches of its information systems and the activities of its clients, customers and counterparties, including vendors. Actions by the financial services industry generally or by certain members or individuals in the industry may have a significant adverse effect on Trustmark's reputation. Trustmark could also suffer significant reputational harm if it fails to properly identify and manage potential conflicts of interest. Management of potential conflicts of interests has become increasingly complex as Trustmark expands its business activities through more numerous transactions, obligations and interests with and among its clients. The actual or perceived failure to adequately address conflicts of interest could affect the willingness of clients to deal with Trustmark, which could adversely affect Trustmark's businesses.

**Risk Related to Acquisition Activity**

*Potential acquisitions by Trustmark may disrupt Trustmark's business and dilute shareholder value.*

Trustmark continuously monitors the market for merger or acquisition opportunities and, depending upon business and other considerations, may elect to pursue one or more such opportunities in the future. Any such merger or acquisition candidate would need to have a similar culture to Trustmark, have experienced management and possess either significant market presence or have potential for improved profitability through financial management, economies of scale or expanded services. Acquiring other banks, businesses,

------

or branches involves various risks commonly associated with acquisitions, including: potential exposure to unknown or contingent liabilities of the target company, exposure to potential asset quality issues of the target company, difficulty and expense of integrating the operations and personnel of the target company, potential disruption to Trustmark's business, potential diversion of Trustmark's Management's time and attention, the possible loss of key employees and customers of the target company, difficulty in estimating the value of the target company and potential changes in banking or tax laws or regulations that may affect the target company. Acquisitions may involve the payment of a premium over book and market values, and, therefore, some dilution of Trustmark's tangible book value and net income per share of common stock may occur in connection with any future transaction. Furthermore, failure to realize the expected revenue projections, cost savings, increases in geographic or product presence, and/or other projected benefits from an acquisition could have a material adverse effect on Trustmark's financial condition or results of operations.

**General Risk Factors**

*The stock price of financial institutions, like Trustmark, can be volatile.*

The volatility in the stock prices of companies in the financial services industry, such as Trustmark, may make it more difficult for shareholders to resell Trustmark common stock at attractive prices in a timely manner. Trustmark's stock price can fluctuate significantly in response to a variety of factors, including factors affecting the financial industry as a whole, such as the bank failures in Spring 2023. The factors affecting financial stocks generally and Trustmark's stock price in particular include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•actual or anticipated variations in earnings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•changes in analysts' recommendations or projections;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•operating and stock performance of other companies deemed to be peers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•perception in the marketplace regarding Trustmark, its competitors and/or the industry as a whole;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•significant acquisitions or business combinations involving Trustmark or its competitors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•provisions in Trustmark's by-laws and articles of incorporation that may discourage takeover attempts, which may make Trustmark less attractive to a potential purchaser;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•changes in government regulation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•failure to integrate acquisitions or realize anticipated benefits from acquisitions; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•volatility affecting the financial markets in general.

General market fluctuations, the potential for breakdowns on electronic trading or other platforms for executing securities transactions, industry factors and general economic and political conditions could also cause Trustmark's stock price to decrease regardless of operating results.

*Changes in accounting standards may affect how Trustmark reports its financial condition and results of operations.*

Trustmark's accounting policies and methods are fundamental to how Trustmark records and reports its financial condition and results of operations. From time to time, the FASB changes the financial accounting and reporting standards that govern the preparation of Trustmark's financial statements. The most recent economic recession resulted in increased scrutiny of accounting standards by regulators and legislators, particularly as they relate to fair value accounting principles. In addition, ongoing efforts to achieve convergence between generally accepted accounting principles (GAAP) and International Financial Reporting Standards may result in changes to GAAP. Any such changes can be difficult to predict and can materially affect how Trustmark records and reports its financial condition or results of operations. For additional details regarding recently adopted and pending accounting pronouncements, see Note 1 – Significant Accounting Policies included in Part II. Item 8. – Financial Statements and Supplementary Data of this report.

*Trustmark may not be able to attract or retain key employees.*

Trustmark's success depends substantially on its ability to attract and retain skilled, experienced personnel. Competition for qualified candidates in the activities and markets that Trustmark serves is intense. While Trustmark invests significantly in the training and development of its employees, it is possible that Trustmark may not be able to retain key employees. If Trustmark were unable to retain its most qualified employees, its performance and competitive positioning could be materially adversely affected.

------

*Natural disasters, such as hurricanes, could have a significant negative impact on Trustmark's business.*

Many of Trustmark's loans are secured by property or are made to businesses in or near the Gulf Coast regions of Alabama, Florida, Mississippi and Texas, which are often in the path of seasonal hurricanes. Natural disasters, such as hurricanes, could have a significant negative impact on the stability of Trustmark's deposit base, the ability of borrowers to repay outstanding loans and the value of collateral securing loans, and could cause Trustmark to incur material additional expenses. Although Management has established disaster recovery policies and procedures, the occurrence of a natural disaster, especially if any applicable insurance coverage is not adequate to enable Trustmark's borrowers to recover from the effects of the event, could have a material adverse effect on Trustmark's financial condition or results of operations.

*Expectations around Environmental, Social and Governance (ESG) practices as well as climate change and related regulatory initiatives could adversely affect Trustmark's business and results of operations, including indirectly through impact to its customers.*

Stakeholders' expectations regarding ESG practices, as well as climate-related legislative and regulatory initiatives, continue to evolve. Institutional investors, and investor advocacy groups, in particular, are increasingly focused on these matters and expectations in many of these areas can vary widely. In addition, increased ESG related compliance costs could result in increases to Trustmark's overall operational costs. Failure to adapt to or comply with regulatory requirements or investor or stakeholder expectations and standards, and fluctuations in these standards, could negatively impact Trustmark's reputation, ability to do business with certain partners and its stock price. New government regulations (including at the state level) could also result in new or more stringent forms of ESG oversight and expanding mandatory and voluntary reporting, diligence and disclosure. Consumers and businesses also may change their behavior on their own as a result of these concerns. It is not possible to predict how climate change may impact Trustmark's financial condition and operations; however, Trustmark operates in areas where its business and the activities of its customers could be impacted by the effects of climate change. The effects of climate change may include increased frequency or severity of weather-related events, such as severe storms, hurricanes, flooding and droughts and rising sea levels. These effects can disrupt business operations, damage property, devalue assets and change customer and business preferences, which may adversely affect borrowers, increase credit risk and reduce demand for Trustmark's products and services. Trustmark and its customers may need to respond to new laws and regulations as well as consumer and business preferences resulting from climate change concerns. Trustmark and its customers may face cost increases, asset value reductions, operating process changes and the like. The impact to Trustmark's customers will likely vary depending on their specific attributes, including reliance on or role in carbon intensive activities. In addition, Trustmark could face reductions in creditworthiness on the part of some customers or in the value of assets securing loans. Trustmark's efforts to take these risks into account may not be effective in protecting it from the negative impact of regulatory initiatives or changes in consumer or business behavior and could have a material adverse effect on Trustmark's financial condition and results of operations.

**ITEM 1B. UNRESOLVED STAFF COMMENTS**

None.

**ITEM 1C. CYBERSECURITY**

Trustmark recognizes the critical importance of identifying, assessing and managing material risks from cybersecurity threats. Trustmark is committed to implementing and maintaining a comprehensive information security program to manage such risks and safeguard its systems and data.

Trustmark's Board of Directors has ultimate oversight of cybersecurity-related risks and it is assisted in this role by the Enterprise Risk Committee and the Audit Committee. Processes for identifying, assessing and managing cybersecurity-related risks are integrated into Trustmark's overall enterprise risk management process, which is overseen by the Enterprise Risk Committee. The Enterprise Risk Committee is responsible for monitoring risks that are being taken by Trustmark, understanding the enterprise-wide effect of those risks and reporting such risks to the Board. In fulfilling this role, the Enterprise Risk Committee has primary oversight responsibility over management's efforts to manage and mitigate cybersecurity-related risk and reviews and approves Trustmark's cybersecurity strategy for protecting Trustmark's information assets and technology platforms. The Audit Committee oversees Trustmark's Internal Audit Department, which conducts reviews and assessments related to information security. Management provides periodic reports to the Enterprise Risk Committee and the Audit Committee, both of which provide reports of their meetings to the full Board. These reports to the Board and its Committees address the threat environment, vulnerability assessments, specific cyber incidents and management's efforts to monitor, detect and prevent cyber threats.

Trustmark's information security program is primarily administered at the management level by the Information Security Department, which is led by Trustmark's Chief Information Security Officer (CISO), and is supported by the Information Technology Department, which is led by Trustmark's Chief Information Officer (CIO). The CISO reports to the CIO, who in turn reports to Trustmark's Chief Credit and Operations Officer. Trustmark's Information Security Department is responsible for day-to-day management of Trustmark's

------

information security program, including data loss prevention, access control, threat monitoring, incident response, insider threat monitoring and employee education and training. The Information Security Department also maintains policies related to cybersecurity and data security that provide the required governance for the information security program. Additionally, Trustmark's Information Technology Department maintains policies that govern technical aspects of Trustmark's information security program. Each policy is reviewed and approved by the Enterprise Risk Committee in accordance with Trustmark's Policy Framework and is mapped to applicable regulatory guidance. The Cybersecurity Operations team within the Information Technology Department maintains and runs Trustmark's security operations center and is responsible for cybersecurity event management and maintaining security tooling. Trustmark also maintains an Information Security / Cybersecurity Management Committee, which is comprised of representatives from the Information Security, Information Technology, Enterprise Risk, Corporate Security, Internal Audit and Legal departments and members of executive management. This committee meets quarterly to discuss and review Trustmark's information security program and receives qualitative and quantitative update reports from the Information Security Department, Internal Audit Department and Information Technology Department.

Trustmark engages third party assessors, consultants and auditors in connection with its information security program, including to conduct external penetration testing, independent audits and risk assessments. Trustmark also utilizes third party service providers in the ordinary course of business. The Information Security Department performs information security assessments for third party service providers that store or process Trustmark confidential data. These information security assessments include a review of any systems and organization control reports, proof of the vendor's independent testing of their data protection controls, as well as a review of any exceptions noted and assessment of management responses, results of vulnerability and penetration testing, incident response processes and third party data protection controls (which can include, but is not limited to: access reviews and controls, backups, monitoring, encryption standards and disaster recovery). The review of these areas is taken into account in order to provide an overall information security conclusion and risk rating for the vendor.

As a regulated financial institution, Trustmark is also subject to financial privacy laws and its cybersecurity practices are subject to oversight by the federal banking agencies. For additional information, see "Supervision and Regulation – Financial Privacy Laws and Cybersecurity" included in Part I. Item 1 – Business of this report.

Although Trustmark has not, as of the date of this Annual Report on Form 10-K, experienced a cybersecurity threat or incident that materially affected its business strategy, results of operations or financial condition, there can be no guarantee that Trustmark will not experience such an incident in the future. For additional information regarding the risk Trustmark faces from cybersecurity threats, please see the risk factors titled "*Trustmark may experience disruptions of its operating systems or breaches in its information system security*" and "*Trustmark must utilize new technologies to deliver its products and services, which could require significant resources and expose Trustmark to additional risks, including cyber-security risks*" included in Part I. Item 1A. – Risk Factors of this report.

**ITEM 2. PROPERTIES**

Trustmark's principal offices are housed in its main office building located in downtown Jackson, Mississippi and owned by TB. Trustmark's main office building is primarily allocated for bank use with a small portion available for occupancy by tenants on a lease basis, although such incidental leasing activity is not material to Trustmark's operations. At December 31, 2025, Trustmark, through TB, operated 160 full-service branches, 7 limited-service branches and an automated teller machine (ATM) network, which included 116 ATMs and 138 ITMs at its branches and other locations. In addition, Trustmark operated 8 offices in various locations providing mortgage banking, wealth management and/or corporate lending services. Trustmark leases 28 of its branch and other office locations with the remainder being owned. Trustmark believes its properties are suitable and adequate to operate its financial services business.

**ITEM 3. LEGAL PROCEEDINGS**

Information required in this section is set forth under the heading "Legal Proceedings" of Note 16 – Commitments and Contingencies in Part II. Item 8. – Financial Statements and Supplementary Data of this report.

In accordance FASB ASC Subtopic 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 currently pending legal 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. Management 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.

***Financial Highlights***

*Quarter Ended December 31, 2025*

Trustmark reported net income of $57.9 million, or basic and diluted EPS of $0.97, for the fourth quarter of 2025, compared to net income of $56.3 million, or basic and diluted EPS of $0.92, for the fourth quarter of 2024. Trustmark's reported performance during the quarter ended December 31, 2025, produced a return on average tangible equity of 12.82%, a return on average assets of 1.23%, an average equity to average assets ratio of 11.35% and a dividend payout ratio of 24.74%, compared to a return on average tangible equity

------

of 13.68%, a return on average assets of 1.23%, an average equity to average assets ratio of 10.82% and a dividend payout ratio of 25.00% during the quarter ended December 31, 2024.

The increase in net income when the fourth quarter of 2025 is compared to the fourth quarter of 2024 was principally due to an increase in revenue and a decrease in the PCL, LHFI, partially offset by increases in noninterest expense and income taxes. Revenue totaled $204.1 million for the quarter ended December 31, 2025 compared to $196.8 million for the quarter ended December 31, 2024, an increase of $7.3 million, or 3.7%. The increase in revenue for the fourth quarter of 2025 compared to the same time period in 2024 primarily resulted from an increase in net interest income, principally due to a decline in interest expense on deposits.

Net interest income for the fourth quarter of 2025 totaled $162.9 million, an increase of $7.0 million, or 4.5%, when compared to the fourth quarter of 2024. Interest income totaled $239.3 million for the fourth quarter of 2025, a decrease of $417 thousand, or 0.2%, when compared to the same time period in 2024, principally due to a decline in other interest income primarily due to a decline in the average balance held at the FRBA and the FRB's decision to lower the rate it pays on reserves, partially offset by a slight increase in interest and fees on LHFS and LHFI. Interest expense totaled $76.4 million for the fourth quarter of 2025, a decrease of $7.5 million, or 8.9%, when compared to the same time period in 2024, primarily due to a decline in interest on deposits. Interest expense on deposits totaled $67.7 million for the fourth quarter of 2025, a decline of $8.2 million, or 10.9%, when compared to the fourth quarter of 2024 primarily due to declines in interest expense on brokered and personal certificates of deposit (CDs), all categories of money market demand deposit accounts (MMDA) and commercial interest checking accounts, primarily reflecting a decline in interest rates.

Noninterest income (loss) for the fourth quarter of 2025 totaled $41.2 million, an increase of $285 thousand, or 0.7%, when compared to the fourth quarter of 2024, principally due to an increase in wealth management largely offset by a decline in other, net. Wealth management totaled $11.1 million for the fourth quarter of 2025, an increase of $1.8 million, or 19.5%, when compared to the same time period in 2024, principally due to an increase in income from brokerage and trust management services. Other, net totaled $2.7 million for the fourth quarter of 2025, a decrease of $1.6 million, or 36.1%, when compared to the same time period in 2024, principally due to a decrease in income from other partnership investments and an increase in amortization of tax credit partnerships.

Noninterest expense for the fourth quarter of 2025 totaled $132.2 million, an increase of $7.7 million, or 6.2%, when compared to the fourth quarter of 2024, principally due to an increase in salaries and employee benefits. Salaries and employee benefits totaled $75.1 million for the fourth quarter of 2025, an increase of $5.9 million, or 8.5%, when compared to the fourth quarter of 2024 primarily due to increases in salaries expense, principally due to general merit increases and new associates added during 2025, annual management performance incentive compensation expense and broker commissions expense.

Trustmark's PCL, LHFI for the three months ended December 31, 2025 totaled a negative $550 thousand compared to $7.0 million for the three months ended December 31, 2024, a decrease of $7.5 million, primarily due to positive credit migration partially offset by loan growth and changes in the macroeconomic forecast. The PCL, off-balance sheet credit exposures totaled $1.8 million for the three months ended December 31, 2025 compared to $502 thousand for the three months ended December 31, 2024, an increase of $1.3 million, primarily due to increases in the total reserve rate and unfunded commitments partially offset by positive credit migration. Please see the section captioned "Provision for Credit Losses," for additional information regarding the PCL on LHFI and off-balance sheet credit exposures.

*Year Ended December 31, 2025*

Trustmark's reported performance for the year ended December 31, 2025, produced a return on average tangible equity of 12.97%, a return on average assets of 1.21% and a dividend payout ratio of 25.81%, compared to a return on average tangible equity of 15.20%, a return on average assets of 1.20% and a dividend payout ratio of 25.21% for the year ended December 31, 2024 and a return on average tangible equity of 14.04%, a return on average assets of 0.89% and a dividend payout ratio of 33.95% for the year ended December 31, 2023. Trustmark's average equity to average assets ratio was 11.16%, 9.84% and 8.41% for the years ended December 31, 2025, 2024 and 2023, respectively.

Trustmark completed the sale of FBBI during the second quarter of 2024. As such, financial results for the years ended December 31, 2024 and 2023, consist of both continuing and discontinued operations. The discontinued operations include the financial results of FBBI prior to the sale as well as the net gain on the sale. Trustmark reported net income from continuing operations of $45.2 million and $153.3 million for the years ended December 31, 2024 and 2023, respectively. Trustmark's reported performance from continuing operations for the year ended December 31, 2024 produced a return on average tangible equity of 3.04%, a return on average assets of 0.24% and a dividend payout ratio of 124.32%, compared to a return on average tangible equity of 12.43%, a return on average assets of 0.82% and a dividend payout ratio of 36.65% for the year ended December 31, 2023. The increase in net income from continuing

------

operations when 2025 is compared to 2024 was principally due to an increase in revenue and a decline in PCL, LHFI, partially offset by increases in income taxes and noninterest expense.

Revenue totaled $799.8 million for the year ended December 31, 2025, compared to $561.0 million and $701.3 million for the years ended December 31, 2024 and 2023, respectively, an increase of $238.8 million, or 42.6%, and a decrease of $140.3 million, or 20.0%, respectively. The increase in revenue for 2025 compared to 2024 was principally due to (i) an increase in noninterest income (loss), primarily as a result of the loss on the sale of available for sale securities during the second quarter of 2024 and increases in mortgage banking, net and wealth management, partially offset by a decrease in other, net, and (ii) an increase in net interest income, primarily resulting from a decline in total interest expense and an increase in interest on securities, partially offset by declines in interest and fees from LHFS and LHFI and other interest income.

Net interest income for the year ended December 31, 2025 totaled $636.1 million, an increase of $51.7 million, or 8.8%, when compared to the year ended December 31, 2024. Interest income totaled $948.6 million for the year ended December 31, 2025, a decrease of $11.7 million, or 1.2%, when compared to the year ended December 31, 2024, reflecting declines in interest and fees on LHFS and LHFI, primarily due to a decrease in interest rates, and other interest income, primarily due to a decline in the average balance held at the FRBA and the FRB's decision to lower the rate it pays on reserves, partially offset by an increase in interest on securities, primarily as a result of higher yielding securities purchased during 2025 and the restructuring of the available for sale securities portfolio during the second quarter of 2024. Interest expense totaled $312.5 million for the year ended December 31, 2025, a decrease of $63.4 million, or 16.9%, when compared to the year ended December 31, 2024, reflecting declines in all categories of interest expense. Interest on deposits totaled $274.7 million for 2025, a decrease of $54.7 million, or 16.6%, when compared to 2024, primarily reflecting declines in interest on brokered and personal CDs, personal and commercial MMDA and public and commercial interest checking accounts, principally due to declines in interest rates. Other interest expense for 2025 totaled $20.3 million, a decrease of $6.1 million, or 23.0%, when compared to 2024, primarily due to a decline in interest expense on FHLB advances, principally due to a decline in rates on short-term FHLB advances, partially offset by an increase in subordinated debt issuance cost as a result of the $175.0 million of subordinated notes issued during the fourth quarter of 2025. Interest on federal funds purchased and securities purchased under repurchase agreements totaled $17.5 million for 2025, a decrease of $2.6 million, or 13.0%, when compared to 2024, primarily reflecting declines in the target federal funds rate by the FRB.

Noninterest income (loss) for 2025 totaled $163.6 million, an increase of $187.1 million when compared to 2024, principally due to the $182.8 million loss on the sale of available for sale securities during the second quarter of 2024, and increases in mortgage banking, net and wealth management, partially offset by a decrease in other, net. Mortgage banking, net totaled $33.1 million for 2025, an increase of $6.5 million, or 24.2%, when compared to 2024, primarily reflecting a decrease in the net negative hedge ineffectiveness and increases in the gain on sales of loans, net and mortgage servicing income, net, partially offset by an increase in the run-off of the MSR. Wealth management totaled $40.1 million for 2025, an increase of $2.9 million, or 7.7%, when compared to 2024, primarily due to increases in income from brokerage and trust management services. Other, net totaled $13.4 million for 2025, a decrease of $4.4 million, or 24.7%, when compared to 2024, principally due to the $8.1 million Visa C shares fair value adjustment during the second quarter of 2024 as well as an increase in amortization of tax credit partnerships, partially offset by the $4.8 million noncredit-related loss on the sale of 1-4 family mortgage loans recorded during the second quarter of 2024.

Noninterest expense totaled $512.2 million for 2025, an increase of $26.5 million, or 5.5%, when compared to 2024, principally due to increases in salaries and employee benefits and services and fees. Salaries and employee benefits totaled $283.4 million for the year ended December 31, 2025, an increase of $17.1 million, or 6.4%, when compared to the year ended December 31, 2024, principally due to increases in salaries expense, primarily due to general merit increases and new associates added during 2025, annual management performance incentives, medical insurance expense, commission expense due to the increase in mortgage originations and other salaries expense. Services and fees totaled $109.4 million for 2025, an increase of $7.8 million, or 7.7%, when compared to 2024, principally due to increases in data processing charges related to software, business process outsourcing fees, advertising expense and legal expense.

The PCL, LHFI for 2025 totaled $14.3 million compared to a total PCL, LHFI of $45.9 million for 2024. The PCL, LHFI for 2024 included an $8.6 million PCL, LHFI sale of 1-4 family mortgage loans for the credit-related portion of the loss on the sale of the 1-4 family mortgage loans. The PCL, LHFI, excluding the PCL, LHFI sale of 1-4 family mortgage loans, for 2024 totaled $37.3 million. The PCL, LHFI, excluding the PCL, LHFI sale of 1-4 family mortgage loans, decreased $23.0 million, or 61.6%, when 2025 is compared to 2024, primarily due to positive credit migration, the resolution of the External Factor – Credit Quality Review qualitative reserve factor and changes to specific reserves associated with individually analyzed credits, partially offset by increases in required reserves related to loan growth, changes in macroeconomic forecasts and updates to other qualitative reserve factors. The PCL, off-balance sheet credit exposures totaled a negative $1.4 million for 2025 compared to a negative $4.7 million for 2024, a decrease in the negative provision of $3.2 million, or 69.1%, primarily due to increases in the total reserve rate and unfunded commitments, partially offset by positive credit migration and the resolution of the External Factor – Credit Quality Review qualitative reserve factor. Please see the section captioned "Provision for Credit Losses" for additional information regarding the PCL on LHFI and off-balance sheet credit exposures.

------

LHFI totaled $13.674 billion at December 31, 2025, an increase of $584.3 million, or 4.5%, compared to December 31, 2024. The increase in LHFI during 2025 was primarily due to net growth in other commercial loans and leases, commercial and industrial LHFI, LHFI secured by real estate and state and other political subdivision LHFI. For additional information regarding changes in LHFI and comparative balances by loan category, see the section captioned "LHFI."

At December 31, 2025, nonperforming assets totaled $91.3 million, an increase of $5.3 million, or 6.2%, compared to December 31, 2024, reflecting increases in both nonaccrual LHFI and other real estate. Total nonaccrual LHFI were $84.4 million at December 31, 2025, an increase of $4.3 million, or 5.3%, relative to December 31, 2024, primarily as a result of mortgage loans placed on nonaccrual in the Mississippi market region, largely offset by the resolution of three large nonaccrual commercial credits in the Alabama and Texas market regions which were reserved for in a prior period. Trustmark's mortgage loans are primarily included in the Mississippi market region because these loans are centrally analyzed and approved as part of the mortgage line of business, which is located in Jackson, Mississippi. The percentage of total loans (LHFS and LHFI) that are 30 days or more past due or classified as nonaccrual increased in 2025 to 1.85% compared to 1.62% in 2024. Other real estate totaled $7.0 million at December 31, 2025, an increase of $1.0 million, or 17.6%, when compared to December 31, 2024, primarily reflecting property foreclosed in the Mississippi and Alabama market regions, largely offset by foreclosed properties sold in the Mississippi, Texas and Alabama market regions.

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 $15.500 billion at December 31, 2025, an increase of $391.6 million, or 2.6%, compared to December 31, 2024. During 2025, noninterest-bearing deposits decreased $37.1 million, or 1.2%, primarily due to a decline in public demand deposit accounts partially offset by increases in commercial and personal demand deposit accounts. Interest-bearing deposits increased $428.7 million, or 3.6%, during 2025, primarily due to growth in all categories of CDs and MMDA as well as commercial interest checking accounts, partially offset by declines in public and consumer interest checking accounts.

Federal funds purchased and securities sold under repurchase agreements totaled $445.0 million at December 31, 2025 compared to $324.0 million at December 31, 2024, an increase of $121.0 million, or 37.3%, principally due to an increase in upstream federal funds purchased. Trustmark had $445.0 million of upstream federal funds purchased at December 31, 2025, compared to $285.0 million at December 31, 2024. Other borrowings totaled $364.8 million at December 31, 2025, an increase of $63.2 million, or 21.0%, when compared with $301.5 million at December 31, 2024, principally due to increases in Government National Mortgage Association (GNMA) loans eligible for repurchase and outstanding short-term FHLB advances obtained from the FHLB of Dallas.

Subordinated notes totaled $172.0 million at December 31, 2025, compared to $123.7 million at December 31, 2024, an increase of $48.3 million, or 39.0%, as a result of the issuance of $175.0 million of new subordinated notes and the pay-off of $125.0 million of outstanding subordinated notes. During the fourth quarter of 2025, Trustmark issued and sold $175.0 million aggregate principal amount of its 6.00% Fixed-to-Floating Rate Subordinated Notes (the 2025 Notes) due December 1, 2035. The 2025 Notes were sold at an underwriting discount of 1.1%, resulting in net proceeds to Trustmark of $173.1 million before deducting offering expenses. Trustmark used the net proceeds from the offering, after the payment of offering expenses, to repay the outstanding $125.0 million of aggregate principal amount of the subordinated notes issued in 2020 plus accrued interest and for general corporate purposes. See the section captioned "Subordinated Notes" for additional information regarding Trustmark's subordinated debt.

**Critical Accounting Policies and Accounting Estimates**

Trustmark's consolidated financial statements are prepared in accordance with GAAP and follow general practices within the financial services industry. Application of these accounting principles requires Management to make estimates, assumptions and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates, assumptions and judgments are based on historical experience, current information and other factors deemed relevant as of the date of the consolidated financial statements; accordingly, as this information changes, actual financial results could differ from those estimates.

Certain policies inherently have a greater reliance on the use of estimates, assumptions and judgments and, as such, have a greater possibility of producing results that could be materially different than originally reported. An accounting estimate is considered critical if the accounting estimate requires Management to make assumptions about matters with a significant level of uncertainty and if the accounting estimate, or changes to the accounting estimate that are reasonably likely to occur from period to period, have had or are reasonable likely to have a material impact to the consolidated financial statements.

For additional information regarding the accounting policies discussed below, please see Note 1 – Significant Accounting Policies set forth in Part II. Item 8. – Financial Statements and Supplementary Data of this report.

***ACL on LHFI and Off-Balance Sheet Credit Exposures***

*LHFI*

The ACL, LHFI is a valuation account, calculated in accordance with FASB ASC Topic 326, that is deducted from the loans' amortized cost basis to present the net amount expected to be collected on the loans. The ACL, LHFI represents Management's best estimate of current expected credit losses on Trustmark's existing LHFI portfolio considering available information, from internal and external sources, relevant to assessing exposure to credit loss over the contractual term of the instrument. The ACL, LHFI is adjusted through the PCL, LHFI and reduced by the charge off of loan amounts, net of recoveries.

The credit 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. Trustmark's overall ACL methodology incorporates various qualitative factors, including economic conditions and concentrations of credit, nature and volume of the portfolio, performance trends and external factors. The economic conditions and concentrations of credit qualitative factor was created for the loans secured by NFNR properties and the loans secured by other real estate loan class, two of Trustmark's largest loan classes, to address changes in the economic conditions of metropolitan areas and apply additional pool level reserves based on third-party market data and forecast trends. The performance trend qualitative reserve factor is utilized to incorporate changes in credit quality and is based on migration analyses that allocate additional ACL to non-pass/delinquent loans within each loan pool. The nature and volume of the portfolio qualitative factor applies to a sub-pool of the LHFI secured by 1-4 family residential properties and utilizes a weighted average remaining maturity (WARM) methodology that uses industry data for the PD and LGD assumptions to support the qualitative adjustment. During the first quarter of 2025, Management elected to utilize Trustmark's historical data to develop a PD based on the credit score ranges initially established as well as the same LGD value from the mortgage sale that occurred in the second quarter of 2024 along with the same weighted average life assumption utilized to determine the credit mark on this portfolio. 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. During the third quarter of 2024, Trustmark activated the External Factor – Credit Quality Review qualitative factor. This qualitative factor ensures reserve adequacy for collectively evaluated commercial loans that may not have been identified and downgraded timely for various reasons. This qualitative factor population is all commercial loans risk rated 1-5. These loans are then applied to the historical average of the Watch/Special Mention rated percentage. Then the balance of these loans are applied additional reserves based on the same reserve rates utilized in the performance trends qualitative factor for Watch/Special Mention rated loans. During the third quarter of 2025, Management determined that the risk related to delayed identification and downgrading of commercial loans had sufficiently diminished and, as a result, resolved the External Factor – Credit Quality Review qualitative factor and released the associated reserves.

Evaluations of the portfolio and individual credits are inherently subjective, as they require estimates, assumptions and judgments as to the facts and circumstances of particular situations. Determining the appropriateness of the ACL, LHFI is complex and requires judgment by Management about the effect of matters that are inherently uncertain. While Management utilizes its best judgment and information available, the ultimate adequacy of Trustmark's ACL, LHFI is dependent upon a variety of factors beyond its controls, including the performance of the portfolios, the economy, changes in interest rates and the view of regulatory authorities toward classification of assets. 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 ACL and PCL for LHFI. Given the nature of many of the factors, forecasts and assumptions in the ACL methodology for LHFI, it is not possible to provide meaningful estimates of the impact of any such potential change.

For a complete description of Trustmark's ACL methodology for the LHFI portfolio, please see Note 4 – LHFI and ACL, LHFI included in Part II. Item 8. – Financial Statements and Supplementary Data of this report.

*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 are not unconditionally cancellable. The ACL on off-balance sheet credit exposures is a liability account calculated in accordance with FASB ASC Topic 326 and presented in the accompanying consolidated balance sheets. Adjustments to the ACL on off-balance sheet credit exposures are recorded to PCL, off-balance sheet credit exposures.

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. In addition to the unfunded balances, Trustmark uses a funding rate for loan pools that are considered open-ended. In order to mitigate volatility and incorporate historical experience in the funding rate, Trustmark uses a twelve-quarter moving average. For the closed-ended loan pools, Trustmark takes a conservative approach and uses a 100% funding rate. The expected funding rate is applied to each pool's unfunded commitment balances to ensure that reserves will be applied to each pool based upon balances expected

------

to be funded based upon historical levels. In addition to the funding rate being applied to the unfunded commitment balance, a reserve rate is applied that is loan pool specific and is applied to the unfunded amount, which includes both quantitative and a majority of the qualitative aspects of the current period's expected credit loss rate. During 2024, Management implemented a performance trends qualitative factor for unfunded commitments and an External Factor – Credit Quality Review qualitative factor for unfunded commitments. For both qualitative factors, the same assumptions are applied in the unfunded commitment calculation that are used in the funded balance calculation with the only difference being the unfunded commitment calculation includes the funding rates for the unfunded commitments. The reserves for these two qualitative factors are added to the other calculated reserve to get a total reserve for off-balance sheet credit exposures. During the third quarter of 2025, Management determined that the risk related to delayed identification and downgrading of commercial loans had sufficiently diminished and, as a result, resolved the External Factor – Credit Quality Review qualitative factor and released the associated reserves.

Evaluations of the unfunded commitments are inherently subjective, as they require estimates, assumptions and judgments as to the facts and circumstances of particular situations. Determining the appropriateness of the ACL on off-balance sheet credit exposures is complex and requires judgment by Management about the effect of matters that are inherently uncertain. While Management utilizes its best judgment and information available, the ultimate adequacy of Trustmark's ACL on off-balance sheet credit exposures is dependent upon a variety of factors beyond its control, including the performance of the portfolios, the economy, changes in interest rates and the view of regulatory authorities toward classification of assets. In future periods, evaluations of off-balance sheet credit exposures, in light of the factors and forecasts then prevailing, may result in significant changes in the ACL and PCL on off-balance sheet credit exposures. Given the nature of many of the factors, forecasts and assumptions in the ACL methodology for off-balance sheet credit exposures, it is not possible to provide meaningful estimates of the impact of any such potential change.

For a complete description of Trustmark's ACL methodology for off-balance sheet credit exposures, please see the section captioned "ACL on Off-Balance Sheet Credit Exposures" in Note 16 – Commitments and Contingencies included in Part II. Item 8. – Financial Statements and Supplementary Data of this report.

***MSR***

Trustmark recognizes as assets the rights to service mortgage loans based on the estimated fair value of the MSR when loans are sold and the associated servicing rights are retained. Trustmark has elected to account for the MSR at fair value.

The fair value of the MSR is determined using a valuation model administered by a third party that calculates the present value of estimated future net servicing income. The model incorporates assumptions that market participants use in estimating future net servicing income, including estimates of prepayment speeds, discount rate, escrow account earnings and contractual servicing fee income and costs. Management reviews all significant assumptions at least 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 may result in a decrease in the fair value of the MSR, while a decrease in either assumption may 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 speeds and/or discount rates within ranges that market participants would use in determining the fair value of the MSR requires significant management judgment.

At December 31, 2025, the MSR fair value was $131.3 million. The impact on the MSR fair value of either a 10% adverse change in prepayment speeds or a 100 basis point increase in discount rates at December 31, 2025, would be a decline in fair value of approximately $5.1 million and $5.2 million, respectively. Changes of equal magnitude in the opposite direction would produce similar increases in fair value in the respective amounts. See the section captioned "MSR" in Note 6 – Mortgage Banking included in Part II. Item 8. – Financial Statements and Supplementary Data of this report for additional information regarding the valuation of the MSR.

**Recent Legislative and Regulatory Developments**

For information regarding legislation and regulation applicable to Trustmark, see the section captioned "Supervision and Regulation" included in Part I. Item 1. – Business of this report.

**Non-GAAP Financial Measures**

In addition to capital ratios defined by 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 calculations may not be comparable with other organizations. Also, there may be limits in the usefulness of these measures to investors. As a result, Trustmark encourages readers to consider its audited consolidated financial statements and the notes related thereto in their entirety and not to rely on any single financial measure.

***Significant Non-routine Transactions***

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 net income adjusted for significant non-routine transactions as a measure of its core operating business, which excludes the impact of the items detailed below, as these items are generally not operational in nature. This non-GAAP measure also provides another basis for comparing period-to-period results as presented in the accompanying selected financial data table and the audited 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 audited consolidated financial statements and the notes related

*n/a - Not applicable.*

*Sale of 1-4 Family Mortgage Loans*

During the second quarter of 2024, Trustmark sold a portfolio of 1-4 family mortgage loans that were at least three payments delinquent and/or nonaccrual at the time of selection totaling $56.2 million, which resulted in a loss of $13.4 million ($10.1 million, net of taxes). The portion of the loss related to credit totaled $8.6 million ($6.5 million, net of taxes) and was recorded as adjustments to charge-offs and the PCL, LHFI. The noncredit-related portion of the loss totaled $4.8 million ($3.6 million, net of taxes) and was recorded to noninterest income (loss) in other, net.

*Visa Shares Conversion*

On April 8, 2024, Visa commenced an initial exchange offer expiring on May 3, 2024, for any and all outstanding shares of Visa Class B-1 common stock (Visa B-1 shares). Holders participating in the exchange offer would receive a combination of Visa Class B-2 common stock (Visa B-2 shares) and Visa Class C common stock (Visa C shares) in exchange for Visa B-1 shares that were validly tendered and accepted for exchange by Visa. TB tendered its 38.7 thousand Visa B-1 shares, which were accepted by Visa. In exchange for each Visa B-1 share that was validly tendered and accepted for exchange by Visa, TB received 50.0% of a newly issued Visa B-2 share and newly issued Visa C shares equivalent in value to 50.0% of a Visa B-1 share. The Visa C shares that were received by TB were recognized at fair value, which resulted in a gain of $8.1 million ($6.0 million, net of taxes) and was recorded to noninterest income (loss) in other, net during the second quarter of 2024. During the third quarter of 2024, TB sold all of the Visa C shares for approximately the same carrying value as of June 30, 2024. The Visa B-2 shares were recorded at their nominal carrying value.

*Securities Portfolio Restructuring*

During the second quarter of 2024, Trustmark restructured its investment securities portfolio by selling $1.561 billion of available for sale securities with an average yield of 1.36%, which generated a loss of $182.8 million ($137.1 million, net of taxes) and was recorded to noninterest income (loss) in securities gains (losses), net. Trustmark also purchased $1.378 billion of available for sale securities with an average yield of 4.85%.

------

*Reduction in Force Expense*

During the fourth quarter 2023, Trustmark incurred reduction in force expenses of $1.4 million related to various restructuring initiatives.

*Litigation Settlement Expense*

On October 9, 2023, Trustmark entered into a settlement agreement that resolved all current and potential future claims relating to litigation involving Adams/Madison Timber. As a result of this settlement, Trustmark recognized a one-time charge of $6.5 million of litigation settlement expense during the third quarter of 2023.

On January 13, 2023, TB entered into a settlement agreement relating to the litigation involving the Stanford Financial Group. As a result of this settlement, Trustmark recognized a one-time charge of $100.0 million of litigation settlement expense as well as an additional $750 thousand of legal fees during the fourth quarter of 2022.

**Results of Operations**

***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 Table shows 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 are immaterial.

Net interest income-FTE for the year ended December 31, 2025 increased $50.2 million, or 8.4%, when compared with the year ended December 31, 2024. The increase in net interest income-FTE when 2025 is compared to 2024 was attributable to declines in all categories of interest expense, with the exception of interest on subordinated notes, and an increase in interest on securities available for sale-taxable partially offset by declines in interest and fees on LHFS and LHFI-FTE and other interest income. The net interest margin-FTE for 2025 increased 29 basis points to 3.80% when compared to 2024. The increase in the net interest margin-FTE for 2025 was principally due to declines in the costs of interest-bearing deposits and other short-term borrowings as well as an increase in the yield on securities available for sale, partially offset by declines in yields on LHFS and LHFI and other earning assets.

Average interest-earning assets for 2025 were $17.037 billion compared to $17.010 billion for 2024, an increase of $26.2 million, or 0.2%, reflecting growth in average loans (LHFS and LHFI) partially offset by declines in average securities and average other earning assets. Average loans (LHFS and LHFI) increased $324.9 million, or 2.4%, when 2025 is compared to 2024, primarily attributable to an increase in the average balance of the LHFI portfolio of $302.9 million, or 2.3%. The increase in the average LHFI portfolio when the balances at December 31, 2025 are compared to December 31, 2024 was principally due to net growth in average LHFI secured by real estate and average other commercial loans and leases. See the sections captioned "LHFS" and "LHFI" for additional information regarding changes in the LHFS and LHFI portfolios. Average total securities declined $135.1 million, or 4.3%, when 2025 is compared to 2024, principally due to calls, maturities and pay-downs of the loans underlying GSE guaranteed securities partially offset by purchases of available for sale securities. Average other earning assets decreased $163.6 million, or 29.8%, when 2025 is compared to 2024, primarily due to a decrease in the average balance held at the FRBA.

Interest income-FTE totaled $959.7 million for 2025, a decrease of $13.2 million, or 1.4%, while the yield on total earning assets decreased 9 basis points to 5.63% when compared to 2024. The decrease in interest income-FTE in 2025 primarily reflected declines in interest and fees on LHFS and LHFI-FTE and other interest income, partially offset by an increase in interest on securities available for sale-taxable. During 2025, interest and fees on LHFS and LHFI-FTE decreased $19.9 million, or 2.3%, when compared to 2024, while the yield on loans (LHFS and LHFI) decreased to 6.15% compared to 6.45% reflecting lower interest rates partially offset by the increase in the average balance of the LHFI portfolio. During 2025, other interest income decreased $12.9 million, or 43.4%, when compared to 2024, while the yield on other earning assets decreased to 4.36% compared to 5.41%, primarily due to a decline in the average balance held at the FRBA as well as the FRB's decision to lower the rate it pays on reserves. During 2025, interest on securities available for sale-taxable increased $22.1 million, or 39.5%, when compared to 2024, while the yield on taxable securities available for sale increased to 4.44% compared to 3.13% principally due to higher yielding securities purchased in 2025 as well as the restructuring of the available for sale securities portfolio during the second quarter of 2024.

------

Average interest-bearing liabilities for 2025 totaled $13.042 billion compared to $13.159 billion for 2024, a decrease of $116.9 million, or 0.9%. The decrease in average interest-bearing liabilities was primarily the result of declines in average interest-bearing deposits and average other borrowings. Average interest-bearing deposits for 2025 decreased $59.2 million, or 0.5%, when compared to 2024, reflecting declines in average interest-bearing demand deposits and average savings deposits partially offset by growth in average time deposits. Average other borrowings for 2025 decreased $79.3 million, or 20.4%, when compared to 2024, principally due to a decrease in average short-term FHLB advances outstanding during the year partially offset by an increase in average GNMA loans eligible for repurchase.

Interest expense for 2025 totaled $312.5 million, a decrease of $63.4 million, or 16.9%, when compared with 2024, while the rate on total interest-bearing liabilities decreased to 2.40% compared to 2.86%. The decrease in interest expense for 2025 was principally due to decreases in interest on deposits, interest on other borrowings and interest on federal funds purchased and securities sold under repurchase agreements, partially offset by an increase in interest on subordinated notes. Interest on deposits decreased $54.7 million, or 16.6%, while the rate on interest-bearing deposits decreased to 2.26% compared to 2.70% when 2025 is compared to 2024, primarily due to declines in interest on brokered and personal CDs, personal and commercial MMDA and public and commercial interest checking accounts, principally due to declines in interest rates. Interest on other borrowings decreased $7.4 million, or 43.1%, while the rate on other borrowings decreased to 3.16% compared to 4.42%, when 2025 is compared to 2024, principally due to a decrease in interest expense on FHLB advances, principally due to a decline in rates on short-term FHLB advances. Interest on federal funds purchased and securities sold under repurchase agreements decreased $2.6 million, or 13.0%, while the rate on federal funds purchased and securities sold under repurchase agreements decreased to 4.26% compared to 5.05%, when 2025 is compared to 2024, principally due to a decline in interest expense on upstream federal funds purchased, reflecting declines in the federal funds target rate by the FRB. Interest on subordinated notes increased $1.9 million, or 39.9%, while the rate on subordinated notes increased to 4.99% from 3.84% when 2025 is compared to 2024, primarily due to the accelerated amortization of capitalized costs related to the subordinated notes issued in 2020 which were repaid fully during the fourth quarter of 2025. See the section captioned "Subordinated Notes" for additional information regarding changes in the subordinated notes.

The change in interest due to both volume and yield or rate has been allocated to change due to volume and change due to yield or rate in proportion to the absolute value of the change in each. Tax-exempt income has been adjusted to a tax equivalent basis using the federal statutory corporate tax rate in effect for each of the three years presented. The balances of nonaccrual loans and the related income recognized have been included for purposes of these computations.

***Provision for Credit Losses***

The PCL, LHFI is the amount necessary to maintain the ACL, 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 $14.3 million for 2025, compared to a PCL, LHFI, excluding the PCL, LHFI sale of 1-4 family mortgage loans, of $37.3 million for 2024 and a PCL, LHFI of $27.4 million for 2023. The PCL, LHFI for 2025 primarily reflected an increase in required reserves as a result of loan growth, changes in the macroeconomic forecast and updates to various qualitative reserve factors, partially offset by a decrease in specific reserves for individually analyzed credits, positive credit migration and reserves released associated with the resolution of the External Factor – Credit Quality Review qualitative factor.

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 a negative $1.4 million for 2025 compared to a negative $4.7 million for 2024, and a negative $2.8 million for 2023. The release in PCL on off-balance sheet credit exposures for 2025 primarily reflected a decrease in required reserves as a result of positive credit migration and reserves released associated with the resolution of the External Factor – Credit Quality Review qualitative factor, partially offset by an increase in required reserves as a result of changes in the total reserve rate.

---

*n/m - percentage changes greater than +/- 100% are not considered meaningful*

The increase in mortgage banking, net when 2025 is compared to 2024 was principally due to a decrease in the net negative hedge ineffectiveness and increases in the gain on sales of loans, net and mortgage servicing income, net, partially offset by an increase in the run-off of the MSR. Mortgage loan production totaled $1.528 billion for 2025, an increase of $109.9 million, or 7.8%, when compared to 2024. Loans serviced for others totaled $8.956 billion at December 31, 2025, compared with $8.763 billion at December 31, 2024, and $8.477 billion at December 31, 2023.

Representing a significant component of mortgage banking income is gain on sales of loans, net. The increase in the gain on sales of loans, net when 2025 is compared to 2024 was primarily the result of an increase in the mortgage valuation adjustment. Loan sales increased $16.2 million, or 1.4%, during 2025 to total $1.158 billion compared to an increase of $5.3 million, or 0.5%, during 2024 to total $1.141 billion.

Changes in the various components of noninterest expense for the year ended December 31, 2025 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 2025 is compared to 2024 was principally due to increases in salaries expense, primarily due to general merit increases and new associates added during 2025, annual management performance incentives, medical insurance expense, commission expense due to the increase in mortgage originations and other salaries expense.

*Services and Fees*

The increase in services and fees when 2025 is compared to 2024 was principally due to increases in data processing charges related to software, business process outsourcing fees, advertising expense and legal expense.

*n/m - percentage changes greater than +/- 100% are not considered meaningful*

The decrease in other expense when 2025 is compared to 2024 was principally due to a decrease in FDIC assessment expense, primarily due to a decrease in the assessment rate, which was largely offset by increases in loan expense and other miscellaneous expenses.

| &nbsp;&nbsp;&nbsp;&nbsp;**Consolidated net income from continuing operations** | $224135 | $45210 | $153290 |

---

*General Banking*

Net interest income for the General Banking Segment for 2025 increased $47.9 million, or 8.3%, when compared with 2024, primarily resulting from declines in all categories of interest expense as well as an increase in interest on securities, partially offset by decreases in interest and fees from LHFS and LHFI and other interest income. The PCL (LHFI and off-balance sheet credit exposures) for the General Banking Segment for 2025 totaled $12.9 million compared to a PCL of $41.1 million during 2024 and a PCL of $26.7 million during 2023. For more information on these net interest income items, please see the sections captioned "Financial Highlights" and "Results of Operations."

Noninterest income (loss) for the General Banking Segment increased $183.9 million during 2025, primarily due to the net loss on the sale of available for sale securities and the noncredit-related loss on the sale of 1-4 family mortgage loans during the second quarter of 2024, as well as increases in mortgage banking, net and gain on sale on premises and equipment, partially offset by the gain on the conversion of Visa Class B-1 shares to Visa Class C shares during the second quarter of 2024 and a decrease in cash management service fees and an increase in the amortization of tax credit partnerships. Noninterest income (loss) for the General Banking Segment represented 16.4% of total revenue for 2025, a negative 11.7% for 2024 and 17.2% for 2023. Noninterest income (loss) for the General Banking Segment includes service charges on deposit accounts; wealth management; bank card and other fees; mortgage banking, net; other, net and securities gains (losses), net. For more information on these noninterest income (loss) items, please see the analysis included in the section captioned "Noninterest Income (Loss)."

Noninterest expense for the General Banking Segment increased $25.0 million, or 5.5%, during 2025, principally due to increases in salaries and employee benefits, data processing expenses related to software, outside services and fees, business process outsourcing expense, net occupancy-premise expenses, loan expenses and advertising expense, partially offset by a decrease in FDIC assessment

expense. For more information on these noninterest expense items, please see the analysis included in the section captioned "Noninterest Expense."

*Wealth Management*

During 2025, net income for the Wealth Management Segment increased $4.1 million, or 52.9%, principally due to increases in net interest income and noninterest income partially offset by an increase in noninterest expense. Net interest income for the Wealth Management Segment increased $3.8 million, or 63.4%, when 2025 is compared to 2024. The increase in net interest income for the Wealth Management Segment when 2025 is compared to 2024 was principally due to an increase in earnings credit on liabilities net of cost of funds on assets as well as an increase in interest on loans partially offset by an increase in interest on deposits generated by the Private Banking Group. The PCL for the Wealth Management Segment for 2025 totaled a negative $26 thousand compared to a PCL of $154 thousand during 2024 and a negative PCL of $2.1 million during 2023. Noninterest income for the Wealth Management Segment, which includes income related to investment management, trust and brokerage services, increased $3.1 million, or 8.4%, during 2025, principally due to increases in income from brokerage and trust management services. Noninterest expense increased $1.6 million, or 4.8%, when 2025 is compared to 2024, principally due to an increase in salaries and employee benefits, primarily related to broker commissions, other salaries expense, general merit increases and annual portfolio manager incentives partially offset by a decline in trust commissions.

At December 31, 2025 and 2024, Trustmark held assets under management and administration of $10.931 billion and $9.423 billion and brokerage assets of $2.582 billion and $2.638 billion, respectively.

***Income Taxes***

For the year ended December 31, 2025, Trustmark's combined effective tax rate from continuing operations was 18.4% compared to a negative 32.7% in 2024 and 15.3% in 2023. The negative effective tax rate from continuing operations for the year ended December 31, 2024 was principally due to the significant non-routine transactions that occurred during the second quarter of 2024. Excluding the significant non-routine transactions, Trustmark's combined effective tax rate from continuing operations for 2024 was 16.1%. 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 and other earning assets. Average earning assets totaled $17.037 billion, or 92.1% of total average assets, at December 31, 2025, compared with $17.010 billion, or 91.7% of total average assets, at December 31, 2024, an increase of $26.2 million, or 0.2%.

***Securities***

The securities portfolio is utilized by Management to manage interest rate risk, generate interest income, provide liquidity and use as collateral for public 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 at December 31, 2025 and 2024 was 4.3 and 4.8 years, respectively.

When compared with December 31, 2024, total investment securities increased by $56.4 million, or 1.9%, during 2025. This increase resulted primarily from purchases of available for sale securities and an increase in the fair market value of the available for sale securities, partially offset by calls, maturities and pay-downs of the loans underlying GSE guaranteed securities. Trustmark sold no securities during 2025, compared to $1.561 billion of available for sale securities sold during 2024, generating a loss of $182.8 million.

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 December 31, 2025, the net unamortized, unrealized loss on all transferred securities included in accumulated other comprehensive income (loss) (AOCI) in the accompanying consolidated balance sheets totaled $36.3 million compared to $46.6 million at December 31, 2024.

------

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 December 31, 2025, available for sale securities totaled $1.877 billion, which represented 60.9% of the securities portfolio, compared to $1.693 billion, or 55.9%, at December 31, 2024. At December 31, 2025, unrealized gains, net on available for sale securities totaled $34.4 million compared to unrealized losses, net of $27.0 million at December 31, 2024. At December 31, 2025, available for sale securities consisted of U.S. Treasury securities, direct obligations of government agencies and GSE guaranteed mortgage-related securities.

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 December 31, 2025, held to maturity securities totaled $1.207 billion and represented 39.1% of the total securities portfolio, compared with $1.335 billion, or 44.1%, at December 31, 2024.

The following table details the weighted-average yield for each range of maturities of securities available for sale and held to maturity using the amortized cost at December 31, 2025 (tax equivalent basis):

---

Mortgage-backed securities and collateralized mortgage obligations are included in maturity categories based on their stated maturity date. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations.

Management continues to focus on asset quality as one of the strategic goals of the securities portfolio, which is evidenced by the investment of 100.0% of the portfolio in U.S. Treasury securities, 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 and FRBA, Trustmark does not hold any other equity investment in a GSE.

At December 31, 2025, 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 table above presenting the credit rating of Trustmark's securities is formatted to show the securities according to the credit rating category, and not by category of the underlying security. As noted in the tables above, a significant portion of Trustmark's investment portfolio moved from the Aaa credit rating to the Aa1 to Aa3 credit rating as of December 31, 2025. The change in the credit rating of Trustmark's investment portfolio was the result of Moody's downgrade of the United States' credit rating from Aaa to Aa1 during the second quarter of 2025. The downgrade was primarily due to concerns about the rising federal debt, increasing interest costs and a perceived weakening of the government's ability to respond to future economic shocks.

***LHFS***

At December 31, 2025, LHFS totaled $278.8 million, consisting of $142.5 million of residential real estate mortgage loans in the process of being sold to third parties and $136.3 million of GNMA optional repurchase loans. At December 31, 2024, LHFS totaled $200.3 million, consisting of $102.7 million of residential real estate mortgage loans in the process of being sold to third parties and $97.6 million of GNMA optional repurchase loans. Please refer to the nonperforming assets table that follows for information on GNMA loans eligible for repurchase which are past due 90 days or more.

Trustmark did not exercise its buy-back option on any delinquent loans serviced for GNMA during 2025 or 2024.

For additional information regarding the GNMA optional repurchase loans, please see the section captioned "Past Due LHFS" included in Note 4 – LHFI and ACL, LHFI of Part II. Item 8. – Financial Statements and Supplementary Data of this report.

---

LHFI at December 31, 2025 increased $584.3 million, or 4.5%, compared to December 31, 2024. The increase in LHFI during 2025 was primarily due to net growth in other commercial loans and leases, commercial and industrial LHFI, LHFI secured by real estate and state and other political subdivision LHFI.

LHFI secured by real estate (loans secured by real estate and other loans secured by real estate) increased $95.8 million, or 1.0%, during 2025, reflecting net growth in other real estate secured LHFI, other LHFI secured by 1-4 family residential properties and LHFI secured by 1-4 family residential properties, partially offset by net declines in other construction LHFI, LHFI secured by nonfarm, nonresidential properties (NFNR LHFI) and construction, land development and other land LHFI. Other real estate secured LHFI increased $490.4 million, or 30.0%, during 2025, primarily due to other construction loans that moved to LHFI secured by multi-family residential properties in the Alabama, Texas, Mississippi and Georgia market regions. Excluding other construction loan reclassifications, other real estate secured LHFI declined by $516.6 million, or 31.6%, during 2025, primarily due to declines in LHFI secured by multi-family residential properties in the Alabama and Texas market regions partially offset by growth in LHFI secured by multi-family residential properties in the Georgia and Mississippi market regions. Other LHFI secured by 1-4 family residential properties, which primarily consists of revolving home equity lines of credit, increased $54.0 million, or 8.3%, during 2025 reflecting growth in the Mississippi, Alabama, Florida, Tennessee and Texas market regions. LHFI secured by 1-4 family residential properties increased $52.7 million, or 2.3%, during 2025 primarily due to an increase in mortgage loan originations in the Mississippi market region. LHFI secured by 1-4 family residential properties are primarily included in the Mississippi market region because they are centrally analyzed and approved as part of a specific line of business located at Trustmark's headquarters in Jackson, Mississippi. Other construction loans decreased $234.7 million, or 28.3%, during 2025 primarily due to other construction loans moved to other loan categories upon the completion of the related construction project partially offset by new construction loans in the Alabama, Georgia, Mississippi, Texas and Florida market regions. During 2025, $1.165 billion loans were moved from other construction to other loan categories, including $1.007 billion to multi-family residential loans, $107.6 million to nonowner-occupied loans and $50.5 million to owner-occupied loans. Excluding all reclassifications between loan categories, growth in other construction loans totaled $928.8 million during 2025. NFNR LHFI decreased $228.8 million, or 6.5%, during 2025, principally due to declines in nonowner-occupied loans in all six market regions as well as owner-occupied loans in the Alabama and Florida market region, partially offset by other construction loans that moved to NFNR LHFI in the Mississippi, Alabama, Georgia, Texas and Florida market regions as well as growth in owner-occupied loans in the Mississippi, Texas and Tennessee market regions. Excluding other construction loan reclassifications, the NFNR LHFI portfolio decreased $386.9 million, or 11.0%, during 2025. LHFI secured by construction, land development and other land decreased $37.9 million, or 6.5%, during 2025 principally due to declines in land development loans in Trustmark's Alabama and Texas market regions, unimproved land loans in the Texas, Mississippi, Florida and Tennessee market regions, and 1-4 family construction loans in the Mississippi and Texas market regions.

Other commercial loans and leases increased $230.8 million, or 39.2%, during 2025, principally due to increases in equipment finance leases in the Georgia market region and other commercial loans in the Mississippi, Georgia and Texas market regions, partially offset by declines in other commercial loans in the Alabama and Tennessee market regions. Trustmark's equipment finance leases are primarily reported in the Georgia market region because these leases are centrally analyzed and approved as part of the Equipment Finance line of business which is located in Atlanta, Georgia. Commercial and industrial LHFI increased $158.7 million, or 8.6%, during 2025, primarily due to growth in the Georgia, Alabama and Tennessee market regions, partially offset by a decline in the Mississippi market

region. State and other political subdivision LHFI increased $91.7 million, or 9.5%, during 2025, reflecting growth in the Mississippi, Texas, Georgia and Tennessee market regions, partially offset by declines in the Alabama and Florida market regions.

Item 8. – Financial Statements and Supplementary Data of this report.

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 at December 31, 2025 and 2024 ($ in thousands):

---

| | | |
|:---|:---|:---|
|  | December 31, | December 31, |
|  | 2025 | 2024 |
| Home equity loans | $72895 | $72183 |
| Home equity lines of credit | 497937 | 458327 |
| Percentage of loans and lines for which Trustmark holds first lien | 44.5% | 46.7% |
| Percentage of loans and lines for which Trustmark does not hold first lien | 55.5% | 53.3% |

---

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 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.

In the following tables, LHFI reported by region (along with related nonperforming assets and net charge-offs) are associated with location of origination except for loans secured by 1-4 family residential properties (representing traditional mortgages) credit cards and equipment finance loans and leases. Loans secured by 1-4 family residential properties and credit cards are included in the Mississippi region because they are centrally analyzed and approved as part of a specific line of business located at Trustmark's headquarters in Jackson, Mississippi. The equipment finance loans and leases are primarily reported in the Georgia market region because they are centrally analyzed and approved as part of the Equipment Finance line of business which is located in Atlanta, Georgia.

***ACL on LHFI and Off-Balance Sheet Credit Exposures***

*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 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.

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.

During the second quarter of 2024, Trustmark executed a sale on a portfolio of 1-4 family mortgage loans that were at least three payments delinquent and/or nonaccrual at the time of selection. As a result of this sale, a credit mark was established for a sub-pool of the loans in the sale. Due to the lack of historical experience and the use of industry data for this sub-pool, management elected to use the credit mark for reserving purposes on a go forward basis for this sub-pool that meet the same credit criteria of being three payments delinquent and/or nonaccrual. All loans of the sub-pool that meet the above credit criteria will be removed from the 1-4 family residential properties pool and placed into a separate pool with the credit mark reserve applied to the total balance.

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 was not clear that the models in production would 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), National Home Price Index (HPI), National Commercial Real Estate (CRE) Price Index and the BBB 7-10 Year US Corporate Bond Index. The upper and lower limits are based on the distribution of the macroeconomic variable by selecting extreme percentiles at the upper and lower limits of the distribution, the 1st and 99th percentiles, respectively. These upper and lower limits are then used to calculate the PD for the forecast time period in which the forecasted values are outside of the upper and lower limit range. Additionally, for 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). During the third quarter of 2024, Trustmark activated the External Factor – Credit Quality Review qualitative factor. This qualitative factor ensures reserve adequacy for collectively evaluated commercial loans that may not have been identified and downgraded timely for various reasons. This qualitative factor population is all commercial loans risk rated 1-5. These loans are then applied to the historical average of the Watch/Special Mention rated percentage. Then the balance of these loans are applied additional reserves based on the same reserve rates utilized in the performance trends qualitative factor for Watch/Special Mention rated loans. Then the Watch/Special Mention population is applied the historical Substandard rated percentage and then subsequently applied the Substandard reserve rate utilized in the performance trends qualitative factor as well. The historical Watch/Special Mention and Substandard rated percentage averages captures the weighted-average life of the commercial loan portfolio. Thus, Trustmark will allocate additional reserves to capture the proportion of potential Watch/Special Mention and Substandard rated credits that may not have been categorized as such at any given point in time through the life of the commercial loan portfolio. During the third quarter of 2025, Management determined that the risk related to delayed identification and downgrading of commercial loans

------

had sufficiently diminished and, as a result, resolved the External Factor – Credit Quality Review qualitative factor and released the associated reserves.

The nature and volume of the portfolio qualitative factor is utilized for a sub-pool of the secured by 1-4 family residential properties due to its significant size as well as the underlying nature being different. The nature and volume of the portfolio qualitative factor utilizes a WARM methodology that uses industry data for the assumptions to support the qualitative adjustment. The industry data is used to compile a PD based on credit score ranges along with using the industry data to compile an LGD. The sub-pools of credits are then aggregated into the appropriate credit score bands in which a weighted-average loss rate is calculated based on the PD and LGD for each credit score range. This weighted-average loss rate is then applied to the expected balance for the sub-segment of credits. This total is then used as the qualitative reserve adjustment. During the first quarter of 2025, Management elected to utilize Trustmark's historical data to develop a PD based on the credit score ranges initially set up. Additionally, Management elected to use the same LGD value from the mortgage sale that occurred in the second quarter of 2024 along with the same weighted average life assumption utilized to determine the credit mark on this portfolio.

Trustmark's current quantitative methodologies do not completely incorporate changes in credit quality. As a result, Trustmark utilizes the performance trends qualitative factor. This factor is based on migration analyses, that allocates additional ACL to non-pass/delinquent loans within each pool. In this way, Management believes the ACL will directly reflect changes in risk, based on the performance of the loans with a pool, whether declining or improving.

The performance trends qualitative factor is estimated by properly segmenting loan pools into risk levels by risk rating for commercial credits and delinquency status for consumer credits. A migration analysis is then performed quarterly using a third-party software and the results for each risk level are compiled to calculate the historical PD average for each loan portfolio based on risk levels. This average historical PD rate is updated annually. For the mortgage portfolio, Trustmark uses an internal report to incorporate a roll rate method for the calculation of the PD rate. In addition to the PD rate for each portfolio, Management incorporates the quantitative rate and the k value derived from the Frye-Jacobs method to calculate a loss estimate that includes both PD and LGD. The quantitative rate is used to eliminate any additional reserve that the quantitative reserve already includes. Finally, the loss estimate rate is then applied to the total balances for each risk level for each portfolio to calculate a qualitative reserve.

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 4 – LHFI and ACL, LHFI included in Part II. Item 8. – Financial Statements and Supplementary Data of this report.

At December 31, 2025, the ACL, LHFI was $157.1 million, a decrease of $3.2 million, or 2.0%, when compared with December 31, 2024. The decrease in the ACL, LHFI during 2025 was principally due to a decrease in specific reserves for individually analyzed credits, positive credit migration and reserves released associated with the resolution of the External Factor – Credit Quality Review qualitative factor, partially offset by an increase in required reserves as a result of loan growth, changes in the macroeconomic forecast and updates to various qualitative reserve factors. Allocation of Trustmark's ACL, LHFI represented 0.91% of commercial LHFI and 1.94% of consumer and home mortgage LHFI, resulting in an ACL to total LHFI of 1.15% at December 31, 2025. This compares with an ACL to total LHFI of 1.22% at December 31, 2024, which was allocated to commercial LHFI at 1.10% and to consumer and home mortgage LHFI at 1.62%.

| **Balance at end of period** | $157071 | $160270 | $139367 |

---

The PCL, LHFI, excluding the PCL, LHFI 1-4 family mortgage loans, for 2025 totaled 0.11% of average loans (LHFS and LHFI), compared to 0.28% of average loans (LHFS and LHFI) in 2024 and 0.21% of average loans (LHFS and LHFI) in 2023. The PCL, LHFI,

------

for 2025 primarily reflected an increase in required reserves as a result of loan growth, changes in the macroeconomic forecast and updates to various qualitative reserve factors, partially offset by a decrease in specific reserves for individually analyzed credits, positive credit migration and reserves released associated with the resolution of the External Factor – Credit Quality Review qualitative factor.

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

| &nbsp;&nbsp;&nbsp;&nbsp;**Total net (charge-offs) recoveries** | $(17510) | $(25017) | $(8209) |

---

Charge-offs exceeded recoveries for 2025, resulting in net charge-offs of $17.5 million, or 0.13% of average loans (LHFS and LHFI), compared to net charge-offs of $25.0 million, or 0.19% of average loans (LHFS and LHFI), in 2024, and net charge-offs of $8.2 million, or 0.06% of average loans (LHFS and LHFI), in 2023. Net charge-offs during 2024 included $8.6 million of charge-offs related to the sale of 1-4 family mortgage loans during the second quarter of 2024. Excluding the charge-offs related to the sale of 1-4 family mortgage loans, net charge-offs totaled $16.4 million, or 0.12% of average loans (LHFS and LHFI), in 2024. The increase in net charge-offs, excluding the charge-offs related to the sale of 1-4 family mortgage loans, when 2025 is compared to 2024, was principally due to the increases in charge-offs in the Mississippi and Texas market regions and decreases in recoveries in the Texas and Florida market regions, partially offset by a decline in charge-offs in the Alabama market region and an increase in recoveries in the Mississippi market region.

*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 includes both quantitative and a majority of the qualitative aspects of the current period's expected credit loss rate. During 2024, Management implemented a performance trends qualitative factor for unfunded commitments and an External Factor – Credit Quality Review qualitative factor for unfunded commitments. For both qualitative factors, the same assumptions are applied in the unfunded commitment calculation that are used in the funded balance calculation with the only difference being the unfunded commitment calculation includes the funding rates for the unfunded commitments. The reserves for these two qualitative factors are added to the other calculated reserve to get a total reserve for off-balance sheet credit exposures. During the third quarter of 2025, Management determined that the risk related to delayed identification and downgrading of commercial loans had sufficiently diminished and, as a result, resolved the External Factor – Credit Quality Review qualitative factor and released the associated reserves. See the section captioned "ACL on Off-Balance Sheet Credit Exposures" in Note 16 – Commitments and Contingencies included in Part II. Item 8. – Financial Statements and Supplementary Data 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 PCL, off-balance sheet credit exposures. At December 31, 2025, the ACL on off-balance sheet credit exposures totaled $28.0 million compared to $29.4 million at December 31, 2024, a decrease of $1.4 million, or 4.9%. The PCL, off-balance sheet credit exposures totaled a negative $1.4 million for 2025, compared to a negative PCL, off-balance sheet credit exposures of $4.7 million for 2024 and a negative PCL, off-balance sheet credit exposures of $2.8 million for 2023. The release in PCL, off-balance sheet credit exposures for 2025 primarily reflected a decrease in required reserves as a result of positive credit migration and reserves released associated with the resolution of the External Factor – Credit Quality Review qualitative factor, partially offset by an increase in required reserves as a result of changes in the total reserve rate.

For additional information regarding the Trustmark's serviced GNMA loans eligible for repurchase, please see the section captioned "Loans Held for Sale (LHFS)" included in Note 1 – Significant Accounting Policies of Part II. Item 8. – Financial Statements and Supplementary Data of this report.

*Nonaccrual LHFI*

At December 31, 2025, nonaccrual LHFI totaled $84.4 million, or 0.60% of total LHFS and LHFI, reflecting an increase of $4.3 million, or 5.3%, relative to December 31, 2024, primarily as a result of mortgage loans placed on nonaccrual in the Mississippi market region, largely offset by the resolution of three large nonaccrual commercial credits in the Alabama and Texas market regions which were reserved for in a prior period. Trustmark's mortgage loans are primarily included in the Mississippi market region because these loans are centrally analyzed and approved as part of the mortgage line of business, which is located in Jackson, Mississippi.

For additional information regarding nonaccrual LHFI, see the section captioned "Nonaccrual and Past Due LHFI" in Note 4 – LHFI and ACL, LHFI included in Part II. Item 8. – Financial Statements and Supplementary Data of this report.

*Other Real Estate*

Other real estate at December 31, 2025 increased $1.0 million, or 17.6%, when compared with December 31, 2024, primarily reflecting property foreclosed in the Mississippi and Alabama market regions largely offset by foreclosed properties sold in the Mississippi, Texas and Alabama market regions.

---

Net write-downs of other real estate decreased $956 thousand, or 58.0%, when 2025 is compared to 2024. The decrease in net write-downs of other real estate during 2025 was primarily due to a write-down on a large commercial foreclosed property in the Texas market region during 2024, partially offset by an increase in write-downs of other real estate in the Mississippi and Tennessee market regions and a decrease in recoveries of other real estate in the Alabama market region.

***Deposits***

Trustmark's deposits are its primary source of funding and consist primarily of core deposits from the communities Trustmark serves. Deposits include interest-bearing and noninterest-bearing demand accounts, savings, MMDA, CDs and individual retirement accounts. Total deposits were $15.500 billion at December 31, 2025 compared to $15.108 billion at December 31, 2024, an increase of $391.6 million, or 2.6%, reflecting an increase in interest-bearing deposits accounts and a decline in noninterest-bearing accounts. During 2025, noninterest-bearing deposits decreased $37.1 million, or 1.2%, primarily due to a decline in public demand deposit accounts partially offset by increases in commercial and personal demand deposit accounts. Interest-bearing deposits increased $428.7 million, or 3.6%, during 2025, primarily due to growth in all categories of CDs and MMDA as well as commercial interest checking accounts, partially offset by declines in public and consumer interest checking accounts.

At December 31, 2025, Trustmark's total uninsured deposits were $5.478 billion, or 35.3% of total deposits, compared to $5.359 billion, or 35.5% of total deposits, at December 31, 2024.

The maturities of time deposits that exceed the FDIC insurance limit of $250 thousand at December 31, 2025 are as follows ($ in thousands):

---

| | |
|:---|:---|
| Three months or less | $332632 |
| Over three months through six months | 444845 |
| Over six months through twelve months | 267916 |
| Over twelve months | 4247 |
| &nbsp;&nbsp;&nbsp;&nbsp;**Total time deposits in excess of FDIC insurance limit** | $1049640 |

---

***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 $445.0 million at December 31, 2025 compared to $324.0 million at December 31, 2024, an increase of $121.0 million, or 37.3%, principally due to an increase in upstream federal funds purchased. At December 31, 2025, none of this balance represented customer related transactions, such as commercial sweep repurchase balances, compared to $39.0 million at December 31, 2024. Trustmark discontinued the customer sweep product during the third quarter of 2025. Trustmark had $445.0 million of upstream federal funds purchased at December 31, 2025, compared to $285.0 million at December 31, 2024.

Other borrowings totaled $364.8 million at December 31, 2025, an increase of $63.2 million, or 21.0%, when compared with $301.5 million at December 31, 2024, principally due to increases in GNMA loans eligible for repurchase and outstanding short-term FHLB advances obtained from the FHLB of Dallas.

***Subordinated Notes***

During 2020, Trustmark issued and sold $125.0 million aggregate principal amount of its 3.625% Fixed-to-Floating Rate Subordinated Notes (the 2020 Notes) due December 1, 2030. The 2020 Notes were sold at an underwriting discount of 1.2%, resulting in net proceeds

------

to Trustmark of $123.5 million before deducting offering expenses. At December 31, 2024, the carrying amount of the 2020 Notes was $123.7 million. The 2020 Notes qualified as Tier 2 capital for Trustmark.

During the fourth quarter of 2025, Trustmark issued and sold $175.0 million aggregate principal amount of its 6.00% Fixed-to-Floating Rate Subordinated Notes (the 2025 Notes) due December 1, 2035. The 2025 Notes were sold at an underwriting discount of 1.1%, resulting in net proceeds to Trustmark of $173.1 million before deducting offering expenses. Trustmark used the net proceeds from the offering, after the payment of offering expenses, to repay the $125.0 million of aggregate principal amount of the 2020 Notes plus accrued interest and for general corporate purposes.

The 2025 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 2025 Notes are obligations of Trustmark only and are not obligations of, and are not guaranteed by, any of its subsidiaries, including TB. The 2025 Notes qualify as Tier 2 capital for Trustmark. The 2025 Notes may be redeemed at Trustmark's option under certain circumstances.

From and including the date of issuance to, but excluding, December 1, 2030 (unless redeemed prior to such date), the 2025 Notes bear interest at a rate of 6.00% per year, payable semiannually in arrears on June 1 and December 1 of each year, commencing on June 1, 2026. From and including December 1, 2030 to, but excluding, the maturity date (unless redeemed prior to such date), the 2025 Notes will bear interest at a floating rate per year equal to the Three-Month Term Secured Overnight Financing Rate (SOFR), plus 260 basis points, payable quarterly in arrears on March 1, June 1, September 1 and December 1 of each year, commencing on March 1, 2031.

At December 31, 2025, the carrying amount of the 2025 Notes was $172.0 million.

**Benefit Plans**

***Defined Benefit Plans***

As disclosed in Note 14 – Defined Benefit and Other Postretirement Benefits included in Part II. Item 8. – Financial Statements and Supplementary Data of this report, 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.

At December 31, 2025, the fair value of the Continuing Plan's assets totaled $1.6 million and was exceeded by the projected benefit obligation of $4.3 million by $2.7 million. Net periodic benefit cost equaled $100 thousand in 2025, compared to $177 thousand in 2024 and $262 thousand in 2023.

The fair value of plan assets is determined utilizing current market quotes, while the benefit obligation and periodic benefit costs are determined utilizing actuarial methodology with certain weighted-average assumptions. For 2025, 2024 and 2023, the process used to select the discount rate assumption under FASB ASC Topic 715, *"Compensation-Retirement Benefits,"* takes into account the benefit cash flow and the segmented yields on high-quality corporate bonds that would be available to provide for the payment of the benefit cash flow. Assumptions, which have been chosen to represent the estimate of a particular event as required by GAAP, have been reviewed and approved by Management based on recommendations from its actuaries.

The range of potential contributions to the Continuing Plan is determined annually by the Continuing Plan's actuary in accordance with applicable IRS rules and regulations. Trustmark's policy is to fund amounts that are sufficient to satisfy the annual minimum funding requirements and do not exceed the maximum that is deductible for federal income tax purposes. The actual amount of the contribution is determined annually based on the Continuing Plan's funded status and return on plan assets as of the measurement date, which is December 31. For the plan year ending December 31, 2025, Trustmark's minimum required contribution to the Continuing Plan was $98 thousand; however, Trustmark contributed $109 thousand, $11 thousand in excess of the minimum required. For the plan year ending December 31, 2026, Trustmark's minimum required contribution to the Continuing Plan is expected to be $91 thousand; however, Management and the Board of Directors of Trustmark will monitor the Continuing Plan throughout 2026 to determine any additional funding requirements by the plan's measurement date.

***Supplemental Retirement Plans***

As disclosed in Note 14 – Defined Benefit and Other Postretirement Benefits included in Part II. Item 8. – Financial Statements and Supplementary Data of this report, 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 dates.

At December 31, 2025, the accrued benefit obligation for the supplemental retirement plans equaled $37.1 million, while the net periodic benefit cost equaled $2.2 million in 2025, $2.4 million in 2024 and $2.5 million in 2023. The net periodic benefit cost and projected benefit obligation are determined using actuarial assumptions as of the plans' measurement date. The process used to select the discount rate assumption under FASB ASC Topic 715 takes into account the benefit cash flow and the segmented yields on high-quality corporate bonds that would be available to provide for the payment of the benefit cash flow. At December 31, 2025, unrecognized actuarial losses and unrecognized prior service costs continue to be amortized over future service periods.

**Legal Environment**

Information required in this section is set forth under the heading "Legal Proceedings" of Note 16 – Commitments and Contingencies in Part II. Item 8. – Financial Statements and Supplementary Data of this report.

**Off-Balance Sheet Arrangements**

Information required in this section is set forth under the heading "Lending Related" of Note 16 – Commitments and Contingencies in Part II. Item 8. – Financial Statements and Supplementary Data 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 December 31, 2025, Trustmark's total shareholders' equity was $2.122 billion, an increase of $159.4 million, or 8.1%, when compared to December 31, 2024. The increase in shareholders' equity during 2025 was primarily as a result of net income of $224.1 million, a positive net change in the fair market value of available for sale securities, net of tax, of $46.0 million, a $14.1 million positive net change in the fair market value of cash flow hedges, net of tax, and a decrease in the unrealized net holding losses on securities transferred from available for sale to held to maturity, net of tax, of $10.3 million, partially offset by common stock repurchases of $80.0 million and common stock dividends of $58.5 million.

***Regulatory Capital***

Trustmark and TB are subject to minimum risk-based capital and leverage capital requirements, as described in the section captioned "Capital Adequacy" included in Part I. Item 1. – Business of this report, which are administered by the federal bank regulatory agencies. These capital requirements, as defined by federal regulations, involve quantitative and qualitative measures of assets, liabilities and certain off-balance sheet instruments. Trustmark's and TB's minimum risk-based capital requirements include a capital conservation buffer of 2.5%. 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 TB and limit Trustmark's and TB's ability to pay dividends. At December 31, 2025, Trustmark and TB exceeded all applicable minimum capital standards. In addition, Trustmark and TB met applicable regulatory guidelines to be considered well-capitalized at December 31, 2025. To be categorized in this manner, Trustmark and TB maintained 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 December 31, 2025, which Management believes have affected Trustmark's or TB's present classification.

In 2020, Trustmark enhanced its capital structure with the issuance of $125.0 million of the 2020 Notes. At December 31, 2024, the carrying amount of the 2020 Notes was $123.7 million. For regulatory capital purposes, the 2020 Notes qualified as Tier 2 capital for Trustmark at December 31, 2024.

------

During the fourth quarter of 2025, Trustmark further enhanced its capital structure with the issuance of $175.0 million of the 2025 Notes. The 2025 Notes mature on December 1, 2035 and are redeemable at Trustmark's option under certain circumstances. Trustmark used the net proceeds from the offering, after the payment of offering expenses, to repay the $125.0 million of aggregate principal amount of the 2020 Notes plus accrued interest and for general corporate purposes. At December 31, 2025, the carrying amount of the 2025 Notes was $172.0 million. The 2025 Notes qualified as Tier 2 capital for Trustmark at December 31, 2025. Trustmark may utilize the full carrying value of the 2025 Notes as Tier 2 capital until December 1, 2030 (five years prior to maturity). Beginning December 1, 2030, the 2025 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 December 31, 2025 and 2024. Trustmark intends to continue to utilize $60.0 million in trust preferred securities issued by the Trust as Tier 1 capital up to the regulatory limit, as permitted by the grandfather provision in the Dodd-Frank Act and the Basel III Final Rule.

Refer to the section captioned "Regulatory Capital" included in Note 17 – Shareholders' Equity in Part II. Item 8. – Financial Statements and Supplementary Data of this report for an illustration of Trustmark's and TB's actual regulatory capital amounts and ratios under regulatory capital standards in effect at December 31, 2025 and 2024.

***Dividends on Common Stock***

Dividends per common share for the year ended December 31, 2025, were $0.96 compared to $0.92 for each of the years ended December 31, 2024 and 2023. Trustmark's dividend payout ratio for 2025, 2024 and 2023 was 25.81%, 25.21%, and 33.95%, respectively. Since Trustmark is a holding company and does not conduct operations, its primary source of liquidity are dividends paid from TB and borrowings from outside sources. As a Mississippi state-chartered banking corporation, TB must obtain the approval of the MDBCF prior to declaring or paying a dividend on its common stock. Approval by TB's regulators is required if the total of all dividends declared by TB in any calendar year exceeds the total of its net income for that year combined with its retained net income of the preceding two years. In 2026, TB will have available approximately $227.4 million plus its net income for that year to pay as dividends to Trustmark. The actual amount of any dividends declared in 2026 by Trustmark will be determined by Trustmark's Board of Directors. Trustmark's Board of Directors declared a quarterly cash dividend of $0.25 per share payable of March 15, 2026, to shareholders of record on March 1, 2026. Trustmark's payment of the dividend will be funded fully by a dividend from TB to Trustmark, which the MDBCF approved on January 28, 2026.

***Stock Repurchase Plan***

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. Under the stock repurchase plan effective January 1, 2023 through December 31, 2023, Trustmark did not repurchase any of its outstanding common stock. Under the stock repurchase plan effective January 1, 2024 through December 31, 2024, Trustmark repurchased 203 thousand shares of its common stock valued at $7.5 million. Under the stock repurchase plan effective January 1, 2025 through December 31, 2025, Trustmark repurchased 2.2 million shares of its common stock valued at $80.0 million. On December 2, 2025, Trustmark's Board of Directors authorized a stock repurchase program effective January 1, 2026, under which $100.0 million of Trustmark's outstanding shares may be acquired through December 31, 2026. The repurchase program, which is subject to market conditions and management discretion, will be implemented through open market repurchases or privately negotiated transactions. Under this authority, Trustmark repurchased 163 thousand shares of its common stock valued at $6.5 million during January 2026.

***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 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 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 to $15.280 billion for 2025 and represented approximately 82.6% of average liabilities and shareholders' equity, compared to average deposits of $15.366 billion, which represented 82.8% of average liabilities and shareholders' equity for 2024.

Trustmark had $408.4 million held in an interest-bearing account at the FRBA at December 31, 2025, compared to $297.3 million at December 31, 2024.

Trustmark utilizes brokered deposits to supplement other wholesale funding sources. At December 31, 2025 and 2024, brokered sweep MMDA deposits totaled $9.6 million and $10.6 million, respectively. In addition, Trustmark had $299.9 million of brokered CDs at December 31, 2025 compared to $250.0 million at December 31, 2024.

At December 31, 2025, Trustmark had $445.0 million of upstream federal funds purchased compared to $285.0 million of upstream federal funds purchased at December 31, 2024. Trustmark maintains adequate federal funds lines to provide sufficient short-term liquidity.

Trustmark maintains a relationship with the FHLB of Dallas, which provided $225.0 million of outstanding short-term advances and no long-term advances at December 31, 2025, compared to $200.0 million of outstanding short-term advances and no long-term advances at December 31, 2024. Under the existing borrowing agreement, Trustmark had sufficient qualifying collateral to increase FHLB advances with the FHLB of Dallas by $1.962 billion at December 31, 2025.

Additionally, Trustmark has the ability to leverage its unencumbered investment securities as collateral. At December 31, 2025, Trustmark had approximately $1.371 billion available in unencumbered Treasury and agency securities compared to $1.107 billion at December 31, 2024.

Another borrowing source is the Discount Window. At December 31, 2025, Trustmark had approximately $7.771 billion available in collateral capacity at the Discount Window primarily from pledges of commercial and consumer LHFI, compared with $1.187 billion at December 31, 2024.

During 2020, Trustmark issued and sold $125.0 million aggregate principal amount of the 2020 Notes. At December 31, 2024, the carrying amount of the 2020 Notes was $123.7 million. During the fourth quarter of 2025, Trustmark issued and sold $175.0 million aggregate principal amount of the 2025 Notes. Trustmark used the net proceeds from the offering, after the payment of offering expenses, to repay the existing $125.0 million of aggregate principal amount of the 2020 Notes plus accrued interest and for general corporate purposes. At December 31, 2025, the carrying amount of the 2025 Notes was $172.0 million. The 2025 Notes mature December 1, 2035 and are redeemable at Trustmark's option under certain circumstances. The 2025 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 2025 Notes are obligations of Trustmark only and are not obligations of, and are not guaranteed by, any of its subsidiaries, including TB.

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 December 31, 2025, 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 December 31, 2025, Management is not aware of any events that are reasonably

------

likely to have a material adverse effect on our 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 II. Item 8. – Financial Statements and Supplementary Data of this report for the expected timing of such payments as of December 31, 2025. These include payments related to (i) short-term and long-term borrowings (Note 11 – Borrowings), (ii) operating and finance leases (Note 9 – Leases), (iii) time deposits with stated maturity dates (Note 10 – Deposits) and (iv) commitments to extend credit and standby letters of credit (Note 16 – Commitments and Contingencies).

**Asset/Liability Management**

***Overview***

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.

***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* 

Trustmark engages in a cash flow hedging program to add stability to interest income and to manage its exposure to interest rate movements. Interest rate swaps designated as cash flow hedges involve the receipt of fixed-rate amounts from a counterparty in exchange for Trustmark making variable-rate payments over the life of the agreements without exchange of the underlying notional amount. Interest rate floor spreads designated as cash flow hedges involve the receipt of variable-rate amounts if interest rates fall below the purchased floor strike rate on the contract and payments of variable rate amounts if interest rates fall below the sold floor strike rate on the contract. Trustmark uses such derivatives to hedge the variable cash flows associated with existing and anticipated variable-rate loan assets. At December 31, 2025, the aggregate notional value of Trustmark's interest rate swaps and floor spreads designated as cash flow hedges totaled $1.630 billion compared to $1.500 billion at December 31, 2024.

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 included in interest and fees on LHFS and LHFI totaled $526 thousand, $474 thousand and $57 thousand of amortization expense for the years ended December 31, 2025, 2024 and 2023, respectively. 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 years ended December 31, 2025, 2024 and 2023, Trustmark reclassified a loss, net of tax, of $7.1 million, $13.6 million and $12.3 million, respectively, into interest and fees on LHFS and LHFI. During the next twelve months, Trustmark estimates that $704 thousand 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. Interest rate lock commitments are residential mortgage loan commitments with customers, which guarantee a specified interest rate for a specified period of time. Changes in the fair value of these derivative instruments are recorded as noninterest income (loss) in mortgage banking, net and are offset by the changes in the fair value of forward sales contracts. The gross notional amount of Trustmark's off-balance sheet obligations under these derivative instruments totaled $74.5 million at December 31, 2025, with a positive valuation adjustment of $998 thousand, compared to $52.1 million, with a positive valuation adjustment of $229 thousand at December 31, 2024. 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 (loss) in mortgage banking, net and are offset by changes in the fair value of LHFS. The gross notional amount of Trustmark's off-balance sheet obligations under these derivative instruments totaled $152.0 million at December 31, 2025, with a negative valuation adjustment of $287 thousand, compared to $110.0 million, with a positive valuation adjustment of $679 thousand at December 31, 2024.

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 under GAAP. The total notional amount of these derivative instruments was $345.5 million at December 31, 2025 compared to $311.5 million at December 31, 2024. These exchange-traded derivative instruments are accounted for at fair value with changes in the fair value recorded as noninterest income (loss) 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 $2.6 million for the year ended December 31, 2025, compared to a net negative ineffectiveness of $9.2 million and $6.3 million for the years ended December 31, 2024 and 2023, 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 TB. 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 (loss) in bank card and other fees. Because these derivatives have mirror-image contractual terms, in addition to collateral provisions which mitigate the impact of non-performance risk, the changes in fair value are expected to substantially offset. The offsetting interest rate swap transactions are either cleared through the Chicago Mercantile Exchange for clearable transactions or booked directly with institutional derivatives market participants for non-clearable transactions. The Chicago Mercantile Exchange rules legally characterize variation margin collateral payments made or received for centrally cleared interest rate swaps as settlements rather than collateral. As a result, centrally cleared interest rate swaps included in other assets and other liabilities are presented on a net basis in the accompanying consolidated balance sheets. At December 31, 2025, Trustmark had interest rate swaps with an aggregate notional amount of $1.991 billion related to this program, compared to $1.819 billion at December 31, 2024.

*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 December 31, 2025, the termination value of interest rate swaps in a liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $117 thousand compared to $568 thousand at December 31, 2024. At December 31, 2025 and 2024, Trustmark had posted collateral of $2.2 million and $1.5 million, respectively, against its obligations because of negotiated thresholds and minimum transfer amounts under these agreements. If Trustmark had breached any of these triggering provisions at December 31, 2025, 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 December 31, 2025, Trustmark had entered into ten risk participation agreements as a beneficiary with and aggregate notional amount of $113.7 million compared to eleven risk participation agreements as a beneficiary with and aggregate notional amount of $83.9 million at December 31, 2024. At December 31, 2025, Trustmark had entered into

------

twenty-seven risk participation agreements as a guarantor with an aggregate notional amount of $267.9 million, compared to twenty-eight risk participation agreements as a guarantor with an aggregate notional amount of $229.1 million at December 31, 2024. The aggregate fair values of these risk participation agreements were immaterial at December 31, 2025 and 2024.

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.

**ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

**Market/Interest Rate Risk Management**

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 December 31, 2025 and 2024.

| +100 basis points | 1.5% | 0.4% |

| -200 basis points | -4.8% | -3.0% |

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 2025 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 December 31, 2025 and 2024.

| | | |
|:---|:---|:---|
|  | Estimated % Change | Estimated % Change |
|  | in Net Portfolio Value | in Net Portfolio Value |
| **Change in Interest Rates** | 2025 | 2024 |
| +200 basis points | -0.3% | -1.3% |
| +100 basis points | 0.1% | -0.4% |

---

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 December 31, 2025, the MSR fair value was $131.3 million, compared to $139.3 million at December 31, 2024. The impact on the MSR fair value of a 10% adverse change in prepayment speeds or a 100-basis point increase in discount rates at December 31, 2025 would be a decline in fair value of approximately $5.1 million and $5.2 million, respectively, compared to a decline in fair value of approximately $4.9 million and $5.6 million, respectively, at December 31, 2024. Changes of equal magnitude in the opposite direction would produce similar increases in fair value in the respective amounts.

**Report of Independent Registered Public Accounting Firm**

**Shareholders and the Board of Directors of Trustmark Corporation**

**Jackson, Mississippi**

**Opinions on the Financial Statements and Internal Control over Financial Reporting**

We have audited the accompanying consolidated balance sheets of Trustmark Corporation and subsidiaries (the "Company") as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, changes in shareholders' equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively referred to as the "financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework: (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2025 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework: (2013) issued by COSO.

**Basis for Opinions**

The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's financial statements and an opinion on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

**Definition and Limitations of Internal Control Over Financial Reporting**

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As described in Note 1 - Significant Accounting Policies and Note 4 – LHFI and ACL, LFHI to the consolidated financial statements, the Company uses a third-party software application to calculate the quantitative portion of the allowance for credit losses, which employs a discounted cash flow (DCF) or weighted average remaining maturity (WARM) method by loan pool. A reasonable and supportable forecast is developed through a Loss Driver Analysis (LDA) by loan class. The LDA uses charge off data from Trustmark Bank's Federal Financial Institutions Examination Council (FFIEC) reports to construct a periodic default rate (PDR). The PDR is decomposed into a probability of default (PD). Regressions are run using the data for various macroeconomic variables in order to determine which correlate to the Company's losses. These variables are then incorporated into the application to calculate a quarterly PD using a third-party baseline forecast. Loss given default (LGD) is derived from a method that traces the relationship between LGD and PD over a period of time and projects LGD based on the PD forecast. 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 all other consumer and other loans pools. For commercial and industrial loan pools, the Company uses its own PD and LGD data. The Company utilizes a third-party bond default study to derive the PD and LGD for the obligations of state and political subdivisions pool.

The Company determined that reasonable and supportable forecasts could be made for a twelve-month period for all of its loan pools in which models were developed through the LDA. 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.

Estimating reasonable and supportable forecasts requires significant judgment and could have a material effect on the Company's financial statements. Management leverages economic projections from an independent third party for its forecasts over the forecast period. We identified auditing the reasonableness of forecasts, including the LDA, as a critical audit matter as it involves especially subjective auditor judgment and increased audit effort, including the involvement of specialists.

The primary audit procedures we performed to address this critical audit matter included the following:

Tested the effectiveness of controls over the LDA and reasonable and supportable forecast including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Relevance and reliability of the underlying data including FFIEC data.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Model validation performed by a third-party specialist.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Reasonableness of significant assumptions and judgments applied in the forecast and results of the calculation.

Performed substantive testing over the LDA and reasonable and supportable forecast including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Tested relevance and reliability of underlying data including FFIEC data.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Utilized the work of internal specialists to assist in evaluating the appropriateness and mathematical accuracy of the LDA, methodologies applied, and the relevance and reliability of data used in the development of the forecast models.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Evaluated the reasonableness of significant assumptions and judgments.

**Note 1 – Significant Accounting Policies**

***Business***

Trustmark Corporation (Trustmark) is a bank holding company headquartered in Jackson, Mississippi. Through its subsidiaries, Trustmark operates as a financial services organization providing banking and financial solutions to corporate institutions and individual customers through offices in Alabama, Florida, Georgia, Mississippi, Tennessee and Texas. As previously disclosed, on August 4, 2025, Trustmark's principal subsidiary, Trustmark National Bank, converted from a national banking association to a Mississippi-chartered banking corporation and changed its name to Trustmark Bank (TB). TB is a member bank of the Federal Reserve System and is supervised by the Federal Reserve Bank of Atlanta (FRBA) and the Mississippi Department of Banking and Consumer Finance (MDBCF).

***Basis of Financial Statement Presentation***

The consolidated financial statements include the accounts of Trustmark and all other entities in which Trustmark has a controlling financial interest. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain reclassifications have been made to prior period amounts to conform to the current period presentation.

The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (GAAP). The preparation of financial statements in conformity with these accounting principles requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and income and expense during the reporting periods and the related disclosures. Although Management's estimates contemplate current conditions and how they are expected to change in the future, it is reasonably possible that in 2026 actual conditions could vary from those anticipated, which could affect Trustmark's financial condition and results of operations. Actual results could differ from those estimates.

***Securities***

Securities are classified as either held to maturity or available for sale. Securities are classified as held to maturity and carried at amortized cost when Management has the positive intent and the ability to hold them until maturity. Securities to be held for indefinite periods of time are classified as available for sale and carried at fair value, with the unrealized holding gains and losses reported as a component of other comprehensive income (loss), net of tax. Securities available for sale are used as part of Trustmark's interest rate risk management strategy and may be sold in response to changes in interest rates, changes in prepayment rates and other factors. Management determines the appropriate classification of securities at the time of purchase.

The amortized cost of debt securities classified as securities held to maturity or securities available for sale is adjusted for amortization of premiums and accretion of discounts to maturity of the security using the interest method. Such amortization or accretion is included in interest on securities. Realized gains and losses are determined using the specific identification method and are included in noninterest income as securities gains (losses), net.

Securities transferred from the available for sale category to the held to maturity category are recorded at fair value at the date of transfer. Unrealized holding gains or losses associated with the transfer of securities from available for sale to held to maturity are included in the balance of accumulated other comprehensive income (loss), net of tax, in the consolidated balance sheets. These unrealized holding gains or losses are amortized over the remaining life of the security as a yield adjustment in a manner consistent with the amortization or accretion of the original purchase premium or discount on the associated security.

*ACL on Securities*

Financial Accounting Standards Board (FASB) Accounting Standard Codification (ASC) Topic 326, "Financial Instruments-Credit Losses," requires a current expected credit losses methodology for estimating allowances for credit losses and applies to all financial instruments carried at amortized cost, including securities held to maturity, and makes targeted improvements to the accounting for credit losses on securities available for sale.

Under FASB ASC Topic 326, the ACL is an estimate measured using relevant information about past events, including historical credit loss experience on financial assets with similar risk characteristics, current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the financial assets.

Trustmark adopted a zero-credit loss assumption for certain classes of securities. This zero-credit loss assumption applies to debt issuances of the U.S. Treasury and agencies and instrumentalities of the United States government. The reasons behind the adoption of the zero-credit loss assumption were as follows:

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•High credit rating

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Long history with no credit losses

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Guaranteed by a sovereign entity

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Widely recognized as "risk-free rate"

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Ability and authority to print its own currency

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Currency is routinely held by central banks, used in international commerce, and commonly viewed as reserve currency

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Currently under the U.S. Government conservatorship or receivership

Trustmark continuously monitors any changes in economic conditions, credit downgrades, changes to explicit or implicit guarantees granted to certain debt issuers, and any other relevant information that would indicate potential credit deterioration and prompt Trustmark to reconsider its zero-credit loss assumption.

*<u>Securities Available for Sale</u>*

FASB ASC Subtopic 326-30, "Financial Instruments-Credit Losses-Available-for-Sale Debt Securities," replaced the concept of other-than-temporarily impaired with the ACL. Unlike securities held to maturity, securities available for sale are evaluated on an individual level and pooling of securities is not allowed.

Quarterly, Trustmark evaluates if any security has a fair value less than its amortized cost. Once these securities are identified, in order to determine whether a decline in fair value resulted from a credit loss or other factors, Trustmark performs further analysis as outlined below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Review the extent to which the fair value is less than the amortized cost and observe the security's lowest credit rating as reported by third-party credit ratings companies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The securities that violate the credit loss triggers above would be subjected to additional analysis that may include, but is not limited to: changes in market interest rates, changes in securities credit ratings, security type, service area economic factors, financial performance of the issuer/or obligor of the underlying issue and third-party guarantee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•If Trustmark determines that a credit loss exists, the credit portion of the allowance will be measured using a discounted cash flow (DCF) analysis using the effective interest rate as of the security's purchase date. The amount of credit loss Trustmark records will be limited to the amount by which the amortized cost exceeds the fair value.

The DCF analysis utilizes contractual maturities, as well as third-party credit ratings and cumulative default rates published annually by Moody's Investor Service (Moody's).

Accrued interest receivable is excluded from the estimate of credit losses for securities available for sale and reported in other assets on the consolidated balance sheets.

*<u>Securities Held to Maturity</u>*

FASB ASC Subtopic 326-20, "Financial Instruments-Credit Losses-Measured at Amortized Cost," requires institutions to measure expected credit losses on financial assets carried at amortized cost on a collective or pool basis when similar risks exist. Trustmark uses several levels of segmentation to measure expected credit losses for its held to maturity securities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The portfolio is segmented into agency and non-agency securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The non-agency securities are separated into municipal, mortgage, and corporate securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Each individual segment is categorized by third-party credit ratings.

As discussed above, Trustmark has determined that for certain classes of securities it would be appropriate to assume the expected credit loss to be zero, which include debt issuances of the U.S. Treasury and agencies and instrumentalities of the United States government. This assumption is reviewed and attested to quarterly. Trustmark uses an internally built model to verify the accuracy of third-party provided calculations.

Accrued interest receivable is excluded from the estimate of credit losses for securities held to maturity and included in other assets on the consolidated balance sheets.

Trustmark monitors the credit quality of securities held to maturity on a monthly basis through credit ratings.

------

***LHFS***

Government National Mortgage Association (GNMA) optional repurchase programs allow financial institutions to buy back individual delinquent mortgage loans that meet certain criteria from the securitized loan pool for which the institution provides servicing. At the servicer's option and without GNMA's prior authorization, the servicer may repurchase such a delinquent loan for an amount equal to 100 percent of the remaining principal balance of the loan. Under FASB ASC Topic 860, "Transfers and Servicing," this buy-back option is considered a conditional option until the delinquency criteria are met, at which time the option becomes unconditional. When Trustmark is deemed to have regained effective control over these loans under the unconditional buy-back option, the loans can no longer be reported as sold and must be brought back onto the balance sheet as LHFS, regardless of whether Trustmark intends to exercise the buy-back option. These loans are reported as LHFS with the offsetting liability being reported as short-term borrowings. The fair value option election does not apply to the GNMA optional repurchase loans which do not meet the requirements under FASB ASC Subtopic 825-10 to be accounted for under the fair value option.

Trustmark defers the upfront loan fees and costs related to the LHFS. In general, the LHFS are only retained on Trustmark's consolidated balance sheets for 30 to 45 days before they are pooled and sold in the secondary market. The difference between deferring these loan fees and costs until the loans are sold and recognizing them in earnings as incurred as required by FASB ASC Subtopic 825-10 is considered immaterial. Deferred loan fees and costs are reflected in the basis of the LHFS and, as such, impact the resulting gain or loss when the loans are sold.

***LHFI***

LHFI are loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off and are reported at amortized cost net of the ACL. Amortized cost is the amount of unpaid principal, adjusted for the net amount of direct costs and nonrefundable loan fees associated with lending. The net amount of nonrefundable loan origination fees and direct costs associated with the lending process, including commitment fees, is deferred and accreted to interest income over the lives of the loans using a method that approximates the interest method. Interest on LHFI is accrued and recorded as interest income based on the outstanding principal balance.

Past due LHFI are loans contractually past due 30 days or more as to principal or interest payments. A LHFI is classified as nonaccrual, and the accrual of interest on such loan is discontinued, when the contractual payment of principal or interest becomes 90 days past due on commercial credits and 120 days past due on non-business purpose credits. In addition, a credit may be placed on nonaccrual at any other time Management has serious doubts about further collectability of principal or interest according to the contractual terms, even though the loan is currently performing. A LHFI may remain in accrual status if it is in the process of collection and well-secured. When a LHFI is placed in nonaccrual status, interest accrued but not received is reversed against interest income. Interest payments received on nonaccrual LHFI are applied against principal under the cost-recovery method, until qualifying for return to accrual status. Under the cost-recovery method, interest income is not recognized until the principal balance is reduced to zero. LHFI are restored to accrual status when the ultimate collectability of the total contractual principal and interest is no longer in doubt and the obligation has either been brought current or has performed in accordance with the contractual terms for a reasonable period of time.

*Purchased Credit Deteriorated (PCD) Loans*

Purchased loans which have experienced more than insignificant credit deterioration since origination are considered PCD loans. An initial ACL for PCD loans is determined at acquisition using the same ACL methodology as the LHFI. The initial ACL determined on a collective basis is allocated to individual loans. PCD loans are reported at the amortized cost, which equals the loan purchased price plus the initial ACL. The difference between the amortized cost basis of the PCD loan and the par value of the loan is the noncredit premium or discount, which is amortized into interest income over the life of the loan. Subsequent changes to the ACL are recorded through the PCL, LHFI.

------

Upon adoption of FASB ASC Topic 326, Trustmark elected to maintain pools of loans that were previously accounted for under FASB ASC Subtopic 310-30, "Receivables-Loans and Debt Securities Acquired with Deteriorated Credit Quality," and will continue to account for these pools as a unit of account. Loans are only removed from the existing loan pools if they are written off, paid off or sold. Upon adoption of FASB ASC Topic 326, the ACL was determined for each pool and added to the pool's carrying value to establish a new amortized cost basis. The difference between the unpaid principal balance of the pool and the new amortized cost basis is the noncredit premium or discount which will be amortized into interest income over the remaining life of the pool. Changes to the ACL after adoption of FASB ASC Topic 326 are recorded through the PCL, LHFI.

***ACL on LHFI and Off-Balance Sheet Credit Exposures***

*LHFI*

Trustmark's ACL methodology for LHFI is based upon guidance within FASB ASC Subtopic 326-20 as well as applicable regulatory guidance. The ACL on LHFI is a valuation account that is deducted from the loans' amortized cost basis to present the net amount expected to be collected on the loans. Credit quality within the LHFI portfolio is continuously monitored by Management and is reflected within the ACL on LHFI. The ACL on LHFI is an estimate of expected losses inherent within Trustmark's existing LHFI portfolio. The ACL on LHFI is adjusted through the PCL, LHFI and reduced by the charge off of loan amounts, net of recoveries.

The loan loss estimation process involves procedures to appropriately consider the unique characteristics of Trustmark's LHFI portfolio segments. These segments are further disaggregated into loan classes, the level at which credit risk is estimated. When computing allowance levels, credit loss assumptions are estimated using a model that categorizes loan pools based on loss history, delinquency status and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. Evaluations of the portfolio and individual credits are inherently subjective, as they require estimates, assumptions and judgments as to the facts and circumstances of particular situations. Determining the appropriateness of the allowance is complex and requires judgment by Management about the effect of matters that are inherently uncertain. In future periods, evaluations of the overall LHFI portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the allowance and credit loss expense.

Trustmark estimates the ACL on LHFI using relevant available information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Trustmark uses a third-party software application to calculate the quantitative portion of the ACL on LHFI using a methodology and assumptions specific to each loan pool. The qualitative portion of the allowance is based on general economic conditions and other internal and external factors affecting Trustmark as a whole as well as specific LHFI. Factors considered include the following: lending policies and procedures, economic conditions and concentrations of credit, nature and volume of the portfolio, performance trends, and external factors. The quantitative and qualitative portions of the allowance are added together to determine the total ACL on LHFI, which reflects Management's expectations of future conditions based on reasonable and supportable forecasts.

The methodology for estimating the amount of expected credit losses reported in the ACL on LHFI has two basic components: a collective, or pooled, component for estimated expected credit losses for pools of loans that share similar risk characteristics, and an asset-specific component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans. In estimating the ACL for the collective component, loans are segregated into loan pools based on loan product types and similar risk characteristics.

Trustmark determined that reasonable and supportable forecasts could be made for a twelve-month period for all of its loan pools. To the extent the lives of the loans in the LHFI portfolio extend beyond this forecast period, Trustmark uses a reversion period of four quarters and reverts to the historical mean on a straight-line basis over the remaining life of the loans.

The ACL for individual loans that do not share risk characteristics with other loans is measured as the difference between the discounted value of expected future cash flows, based on the effective interest rate at origination, and the amortized cost basis of the loan, or the net realizable value. The ACL is the difference between the loan's net realizable value and its amortized cost basis (net of previous charge-offs and deferred loan fees and costs), except for collateral-dependent loans. A loan is collateral dependent when the borrower is experiencing financial difficulty and repayment of the loan is expected to be provided substantially through the sale of the collateral. The expected credit loss for collateral-dependent loans is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral, adjusted for the estimated cost to sell. Fair value estimates for collateral-dependent loans are derived from appraised values based on the current market value or the 'as is' value of the collateral, normally from recently received and reviewed appraisals. Current appraisals are ordered on an annual basis based on the inspection date or more often if market conditions necessitate. Appraisals are obtained from state-certified appraisers and are based on certain assumptions, which may include construction or development status and the highest and best use of the property. These appraisals are reviewed by Trustmark's Appraisal Review Department to ensure they are acceptable, and values are adjusted down for costs associated with asset disposal. If the calculated expected credit loss is determined to be permanent or not recoverable, the amount of the expected credit loss is charged off.

------

Accrued interest receivable is not included in the amortized cost basis of Trustmark's LHFI and, therefore, excluded from the estimate of credit losses for LHFI.

LHFI are charged off against the ACL on LHFI, with any subsequent recoveries credited back to the ACL on LHFI account. Recoveries may not exceed the aggregate of amounts previously charged off. Trustmark's Loan Policy Manual dictates the guidelines to be followed in determining when a loan is charged off. Commercial purpose LHFI are charged off when a determination is made that the loan is uncollectible and continuance as a bankable asset is not warranted. Consumer LHFI secured by 1-4 family residential real estate are generally charged off or written down to the fair value of the collateral less cost to sell at no later than 180 days of delinquency. Non-real estate consumer purpose LHFI, including both secured and unsecured loans, are generally charged off by 120 days of delinquency. Consumer revolving lines of credit and credit card debt are generally charged off on or prior to 180 days of delinquency.

*ACL on Off-Balance Sheet Credit Exposures*

Under FASB ASC Subtopic 326-20, Trustmark is required to estimate expected credit losses for off-balance sheet credit exposures which are not unconditionally cancellable. Trustmark maintains a separate ACL on off-balance sheet credit exposures, including unfunded loan commitments and letters of credit.

Expected credit losses for off-balance sheet credit exposures are estimated by calculating a commitment usage factor over the contractual period for exposures that are not unconditionally cancellable by Trustmark. Trustmark calculates a loan pool level unfunded amount for the period. Trustmark views the loan pools as either closed-ended or open-ended. Closed-ended loan pools are those that typically fund up to 100% such as other construction and nonowner-occupied. Open-ended loan pools are those that behave similar to a revolver such as the commercial and industrial, letters of credit and home equity line of credit loan pools. In addition to the unfunded balances, Trustmark uses a funding rate for loan pools that are considered open-ended. Trustmark calculates the funding rate of the open-ended loan pools each period. In order to mitigate volatility and incorporate historical experience in the funding rate, Trustmark uses a twelve-quarter moving average. For the closed-ended loan pools, Trustmark takes a conservative approach and uses a 100% funding rate. The expected funding rate is applied to each pool's unfunded commitment balances to ensure that reserves will be applied to each pool based on balances expected to be funded based upon historical levels. In addition to the funding rate being applied to the unfunded commitment balance, a reserve rate is applied, which includes both quantitative and a majority of the qualitative aspects of the current period's expected credit loss rate. During 2024, Management implemented a performance trends qualitative factor for unfunded commitments and an External Factor – Credit Quality Review qualitative factor for unfunded commitments. For both qualitative factors, the same assumptions are applied in the unfunded commitment calculation that are used in the funded balance calculation with the only difference being the unfunded commitment calculation includes the funding rates for the unfunded commitments. The reserves for these two qualitative factors are added to the other calculated reserve to get a total reserve for off-balance sheet credit exposures. During the third quarter of 2025, Management determined that the risk related to delayed identification and downgrading of commercial loans had sufficiently diminished and, as a result, resolved the External Factor – Credit Quality Review qualitative factor and released the associated reserves. Adjustments to the ACL on off-balance sheet credit exposures are recorded to the PCL, off-balance sheet credit exposures.

No credit loss estimate is reported for off-balance sheet credit exposures that are unconditionally cancellable by Trustmark or for undrawn amounts under such arrangements that may be drawn prior to the cancellation of the arrangement.

***Premises and Equipment, Net***

Premises and equipment are reported at cost, less accumulated depreciation and amortization. Depreciation is charged to expense over the estimated useful lives of the assets, which are up to thirty-nine years for buildings and three to ten years for furniture and equipment. Leasehold improvements are amortized over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. In cases where Trustmark has the right to renew the lease for additional periods, the lease term for the purpose of calculating amortization of the capitalized cost of the leasehold improvements is extended when Trustmark is "reasonably assured" that it will renew the lease. Depreciation and amortization expenses are computed using the straight-line method. Trustmark continually evaluates whether events and circumstances have occurred that indicate that such long-lived assets have become impaired. Measurement of any impairment of such long-lived assets is based on the fair values of those assets.

Branch closures and purchased land held for future branch expansion for more than five years are evaluated to determine if the related land, buildings and building improvements should be transferred to assets held for sale in accordance with FASB ASC Topic 360, "Property, Plant and Equipment." The property is transferred to assets held for sale at the lower of its carrying value or fair value less cost to sell. An impairment loss is recorded at the time of transfer if the carrying value of the assets exceeds the fair value. Impairment losses are recorded as noninterest expense in other expense.

------

***MSR***

Trustmark recognizes as assets the rights to service mortgage loans based on the estimated fair value of the MSR when loans are sold and the associated servicing rights are retained. Trustmark has elected to account for the MSR at fair value.

The fair value of the MSR is determined using a valuation model administered by a third party that calculates the present value of estimated future net servicing income. Estimates of fair value involve several assumptions, including the key valuation assumptions about market expectations of future prepayment rates, interest rates and discount rates which are provided by a third-party firm. Prepayment rates are projected using an industry standard prepayment model. The model considers other key factors, such as a wide range of standard industry assumptions tied to specific portfolio characteristics such as remittance cycles, escrow payment requirements, geographic factors, foreclosure loss exposure, VA no-bid exposure, delinquency rates and cost of servicing, including base cost and cost to service delinquent mortgages. Prevailing market conditions at the time of analysis are factored into the accumulation of assumptions and determination of servicing value.

Trustmark economically hedges changes in the fair value of the MSR attributable to interest rates. See the section titled "Derivative Financial Instruments – Derivatives Not Designated as Hedging Instruments" of this note for information regarding these derivative instruments.

Trustmark receives annual servicing fee income for loans serviced, which is recorded as noninterest income in mortgage banking, net. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. Late fees and ancillary fees related to loan servicing are not considered material.

***Goodwill and Identifiable Intangible Assets***

Trustmark accounts for goodwill and other intangible assets in accordance with FASB ASC Topic 350, "Intangibles – Goodwill and Other." Goodwill, which represents the excess of cost over the fair value of the net assets of an acquired business, is not amortized but tested for impairment on an annual basis, which is October 1 for Trustmark, or more often if events or circumstances indicate that there may be impairment.

Identifiable intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or legal rights or because the assets are capable of being sold or exchanged either on their own or in combination with a related contract, asset or liability. Trustmark's identifiable intangible assets primarily relate to core deposits and borrower relationships. These intangibles, which have definite useful lives, are amortized on an accelerated basis over their estimated useful lives. In addition, these intangibles are evaluated for impairment whenever events and changes in circumstances indicate that the carrying amount should be reevaluated. Trustmark also purchased banking charters in order to facilitate its entry into the states of Florida and Texas. These identifiable intangible assets were amortized on a straight-line method over 20 years.

***Other Real Estate***

Other real estate includes assets that have been acquired in satisfaction of debt through foreclosure and is recorded at the fair value less cost to sell (estimated fair value) at the time of foreclosure. Fair value is based on independent appraisals and other relevant factors. When foreclosed real estate is received in full satisfaction of a loan, the amount, if any, by which the recorded amount of the loan exceeds the estimated fair value of the property is a loss charged against the ACL at the time of foreclosure. If the recorded amount of the loan is less than the estimated fair value of the property, a credit is recorded to write-downs of other real estate at the time of foreclosure.

Other real estate is revalued on an annual basis or more often if market conditions necessitate. An other real estate specific reserve may be recorded through other real estate expense for declines in fair value subsequent to foreclosure based on recent appraisals or changes in market conditions. Subsequent to foreclosure, losses on the periodic revaluation of the property are charged against an existing other real estate specific reserve or as noninterest expense in other real estate expense if a reserve does not exist. Costs of operating and maintaining the properties as well as gains or losses on their disposition are also included in other real estate expense as incurred. Improvements made to properties are capitalized if the expenditures are expected to be recovered upon the sale of the properties.

***Leases***

*Lessor Arrangements*

Trustmark leases certain types of machinery and equipment to its commercial customers through sales-type and direct financing leases as part of its equipment financing portfolio. Sales-type and direct financing leases are similar to other forms of installment lending in that lessors generally do not retain benefits and risks incidental to ownership of the property subject to the leases. Such arrangements

------

are essentially financing transactions that permit lessees to acquire and use property. Trustmark does not have any significant operating leases in which it is the lessor.

As lessor, the sum of all minimum lease payments over the lease term and the estimated residual value, less unearned interest income, is recorded as the net investment in the lease on the commencement date and is included in LHFI on the consolidated balance sheets. Trustmark has made an accounting policy election to exclude from consideration in the contract and from variable payments not included in the consideration in the contract the taxes assessed and collected from the lessee in accordance with FASB ASC Subtopic 842-10-15-39A. Interest income is accrued as earned over the term of the lease based on the net investment in the leases and is recognized in interest and fees on LHFS and LHFI on the consolidated statements of income. Certain fees or costs associated with lease originations are deferred and accreted or amortized to interest income over the life of the lease using the effective interest method.

Trustmark's portfolio of sales-type and direct financing leases generally have remaining lease terms of three to ten years, some of which include renewal options and/or options for the lessee to purchase the leased property near or at the end of the lease term at either the residual value or a specified price. Trustmark expects to sell or release the equipment at the end of the lease term. Due to the structure of these leases, there is no selling profit or loss on these transactions.

*Lessee Arrangements*

Trustmark has certain contracts that it has identified as leases according to FASB ASC Topic 842, "Leases". Trustmark classifies these leases as either operating or finance leases and recognizes a right-of-use asset and a lease liability at the lease commencement date. The lease liability represents the present value of the lease payments that remain unpaid as of the commencement date and the right-of-use asset is the initial lease liability recognized for the lease plus any lease payments made to the lessor at or before the commencement date as well as any initial direct costs less any lease incentives received. Trustmark accounts for the lease and nonlease components separately as such amounts are readily determinable.

Trustmark's finance leases consist of building leases. Trustmark recognizes interest expense based on the discount rate of the lease as interest expense in other interest expense and recognizes depreciation expense on a straight-line basis over the lease term as noninterest expense in net occupancy – premises for building leases and in equipment expense for equipment leases. Trustmark amortizes the right-of-use asset over the life of the lease term on a straight-line basis. Trustmark's lease liabilities are measured as the present value of the remaining lease payments throughout the lease term. Trustmark records its finance lease right-of-use assets in premises and equipment, net and its finance lease liabilities in other borrowings.

Trustmark's operating leases primarily consist of building and land leases. Trustmark recognizes lease rent expense on a straight-line basis over the term of the lease contract and records it as noninterest expense in net occupancy – premises for building and land leases and in equipment expense for equipment leases. Trustmark's amortization of the right-of-use asset is the difference between the straight-line lease expense and the interest expense recognized on the lease liability during the period. Trustmark's lease liabilities are measured as the present value of the remaining lease payments throughout the lease term.

Trustmark's leases typically have one or more renewal options included in the lease contract. Due to the nature of Trustmark's leases, for leases with renewal options available, Trustmark considers the first renewal option as reasonably certain to renew and is therefore included in the measurement of the right-of-use assets and lease liabilities.

In order to calculate its right-of-use assets and lease liabilities, FASB ASC Topic 842 requires Trustmark to use the rate of interest implicit in the lease when readily determinable. If the rate implicit in the lease is not readily determinable, Trustmark is required to use its incremental borrowing rate, which is the rate of interest Trustmark would have to pay to borrow on a collateralized basis over a similar term in a similar economic environment. Trustmark was able to determine the implicit interest rate for its equipment leases and used that rate as its discount rate. Since the implicit interest rate for most of its building and land leases were not readily determinable, Trustmark used its incremental borrowing rate.

Trustmark made an accounting policy election to not recognize short-term leases (12 months or less) on the consolidated balance sheets. Trustmark's short-term leases primarily include automated teller machines. For short-term leases, Trustmark recognizes lease expense on a straight-line basis over the lease term.

***Federal Home Loan Bank (FHLB) and FRBA Stock***

Trustmark accounts for its investments in FHLB and FRBA stock in accordance with FASB ASC Subtopic 942-325, "Financial Services-Depository and Lending-Investments-Other." FHLB and FRBA stock are equity securities that do not have a readily determinable fair value because its ownership is restricted and it lacks a market. FHLB and FRBA stock are carried at cost and evaluated for impairment. Trustmark's investment in member bank stock is included in other assets in the accompanying consolidated balance sheets. At December

------

31, 2025 and 2024, Trustmark's investment in member bank stock totaled $42.0 million and $44.9 million, respectively. The carrying value of Trustmark's member bank stock gave rise to no other-than-temporary impairment for the years ended December 31, 2025, 2024 and 2023.

***Revenue from Contracts with Customers***

Trustmark accounts for revenue from contracts with customers in accordance with FASB ASC Topic 606, "Revenue from Contracts with Customers," which provides that revenue be recognized in a manner that depicts the transfer of goods or services to a customer in an amount that reflects the consideration Trustmark expects to be entitled to in exchange for those goods or services. Revenue from contracts with customers is recognized either over time in a manner that depicts Trustmark's performance, or at a point in time when control of the goods or services are transferred to the customer. Trustmark's noninterest income, excluding all of mortgage banking, net and securities gains (losses), net and portions of bank card and other fees and other, net, are considered within the scope of FASB ASC Topic 606. Gains or losses on the sale of other real estate, which are included in Trustmark's noninterest expense as other expense, are also within the scope of FASB ASC Topic 606.

*General Banking Segment*

*<u>Service Charges on Deposit Accounts</u>*

In general, deposit accounts represent contracts with customers with no fixed duration and can be terminated or modified by either party at any time without compensation to the other party. According to FASB ASC Topic 606, a contract that can be terminated by either party without compensation does not exist for periods beyond the then-current period. Therefore, deposit contracts are considered to renew day-to-day if not minute-to-minute.

Deposit contracts have a single continuous or stand-ready service obligation whereby Trustmark makes customer funds available for use by the customer as and when the customer chooses as well as other services such as statement rendering and online banking. The specific services provided vary based on the type of deposit account. These services are not individually distinct, but are distinct as a group, and therefore, constitute a single performance obligation which is satisfied over time and qualifies as a series of distinct service periods.

Trustmark receives a fixed service charge amount as consideration monthly for services rendered. The service charge amount varies based on the type of deposit account. Some of the service charge revenue is subject to refund provisions, which is variable consideration under the guidelines of FASB ASC Topic 606. Trustmark has elected the 'as-invoiced' practical expedient permitted under FASB ASC Topic 606 for recognition of service charge revenue. Therefore, revenue is recognized at the time and in the amount the customer is charged. The service charge revenue is presented net of refunded amounts on Trustmark's consolidated statements of income.

Services related to non-sufficient funds, overdrafts, excess account activity, stop payments, dormant accounts, etc. are considered optional purchases for a deposit contract because there is no performance obligation for Trustmark until the service is requested by the customer or the occurrence of a triggering event. Fees for these services are fixed amounts and are charged to the customer when the service is performed. Revenue is recognized at the time the customer is charged.

*<u>Bank Card and Other Fees</u>*

Revenue from contracts with customers in bank card and other fees includes income related to interchange fees and various other contracts which primarily consists of contracts with a single performance obligation that is satisfied at a point in time. Trustmark receives a fixed consideration amount once the performance obligation is completed for these contracts. Trustmark reports revenue from these contracts net of amounts refunded or due to a third party.

As both a debit and credit card issuer, Trustmark receives an interchange fee for every card transaction completed by its customers with a merchant. Trustmark receives two types of interchange fees: point-of-sale transactions in which the customer must enter the PIN associated with the card to complete the transaction (a debit card transaction), and signature transactions in which the signature (physical or electronic) of the customer is required to complete the transaction or the transaction is completed using Near Field Communication (NFC) or EMV chip technology (a credit card transaction).

Trustmark, as the card issuing or settlement bank, has a contract (implied based on customary business practices) with the payment network in which Trustmark has a single continuous service obligation to make funds available for settlement of the card transaction. Trustmark's service obligation is satisfied over time and qualifies as a series of distinct service periods. Trustmark receives interchange fees as consideration for services rendered in the amount established by the respective payment network. The interchange fees are

------

established by the payment network based on the type of transaction and is posted on their website. Trustmark receives and records interchange fee revenue from the payment networks daily net of all fees and amounts due to the payment network.

*<u>Other Income</u>*

Revenue from contracts with customers in other income includes income related to cash management services and other contracts with a single performance obligation that is satisfied at a point in time. Trustmark receives a fixed consideration amount once the performance obligation is completed for these contracts. Trustmark reports revenue from these contracts net of amounts refunded or due to a third party.

Trustmark provides cash management services through the delivery of various products and services offered to its business and municipal customers including various departments of state, city and local governments, universities and other non-profit entities. Similar to the deposit account contracts, the cash management contracts primarily represent contracts with customers with no fixed duration and can be terminated or modified by either party at any time without compensation to the other party. Therefore, cash management contracts are generally considered to renew day-to-day if not minute-to-minute.

Cash management contracts have a single continuous or stand-ready service obligation whereby Trustmark makes a specific service or group of services available for use by the customer as and when the customer chooses. The specific services provided vary based on the type of account or product. These services are not individually distinct, but are distinct as a group, and therefore, constitute a single performance obligation which is satisfied over time and qualifies as a series of distinct service periods.

Trustmark receives a set service charge or maintenance fee amount as consideration monthly for services rendered. However, some of the fees are based on the number of transactions that occur (*i.e.,* flat fee for a set number of transactions per month then an additional charge for each transaction after that) or the average daily account balance maintained by the customer during the month and a small amount of the cash management fee revenue is subject to refund provisions. These fees represent variable consideration under the guidelines of FASB ASC Topic 606. Trustmark has elected the 'as-invoiced' practical expedient permitted under FASB ASC Topic 606 for recognition of cash management fee revenue. The cash management revenue is presented net of any refunded amounts on Trustmark's consolidated statements of income.

Trustmark's merchant services provider contracts directly with Trustmark business customers and provides Trustmark's merchant customers card processing equipment and transaction processing services. Trustmark's contract with the merchant services provider has a single-continuous service obligation to provide customer referrals for potential new accounts which is satisfied over time and qualifies as a series of distinct service periods. Trustmark receives a flat fee for each new account established and a percentage of the residual income related to transactions processed for Trustmark's merchant customers each month as provided in the contract. Under the guidelines of FASB ASC Topic 606, the fee received for each new account and the profit sharing represent variable consideration. Revenue from merchant card services contracts is recognized monthly using a time-elapsed measure of progress. Trustmark has elected the 'as-invoiced' practical expedient permitted under FASB ASC Topic 606 for recognition of the merchant card services revenue.

*<u>Other Real Estate</u>*

Trustmark records a gain or loss from the sale of other real estate when control of the property transfers to the buyer. Trustmark records the gain or loss from the sale of other real estate in noninterest expense as other expense. Other real estate sales for the year ended December 31, 2025 resulted in a net loss of $1.8 million compared to a net loss of $1.1 million for the year ended December 31, 2024 and a net loss of $145 thousand for the year ended December 31, 2023.

In general, purchases of Trustmark's other real estate property are not financed by Trustmark. Financing the purchase of other real estate is evaluated based upon the same lending policies and procedures as all other types of loans. Under FASB ASC Subtopic 610-20, "Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets," when Trustmark finances the sale of its other real estate to a buyer, Trustmark is required to assess whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these two criteria are met, Trustmark derecognizes the other real estate asset and records a gain or loss on the sale once control of the property is transferred to the buyer.

*Wealth Management Segment*

*<u>Trust Management</u>*

There are four categories of revenue included in trust management: personal trust and investments, retirement plan services, institutional custody and other. Each of these categories includes multiple types of contracts, service obligations and fee income. However, the majority of these contracts include a single service obligation that is satisfied over time, the customer is charged in arrears for services

------

rendered and revenue is recognized when payment is received. In general, the time period between when the service obligation is completed and when payment from the customer is received is less than 30 days. Revenue from trust management contracts is primarily related to monthly service periods and based on the prior month-end's market value. Some trust management revenue is mandated by a court order, while other revenue consists of flat fees. Trust management revenue based on an account's market value represents variable consideration under the guidelines of FASB ASC Topic 606. Trustmark has elected the 'as-invoiced' practical expedient allowed under FASB ASC Topic 606 to account for the trust management revenue.

Assets under administration held by Trustmark in a fiduciary or agency capacity for customers are not included in Trustmark's consolidated balance sheets.

*<u>Investment Services</u>*

Investment services includes both brokerage and annuity income. Trustmark has a contract with a third-party investment services company which contains a single continuous service obligation, to provide broker-dealer and advisory services to customers on behalf of the third-party, which is satisfied over time and qualifies as a series of distinct service periods. Trustmark serves as the agent between the third-party investment services company, the principle, and the customer. In accordance with the contract, Trustmark receives a monthly payment from the investment services company for commissions and advisory fees (asset management fees) earned on transactions completed in the prior month net of all charges and fees due to the investment services company. Trustmark recognizes revenue from the investment services company, net of the revenue sharing expense due to the investment services company, when the payments are received. Commissions vary from month-to-month based on the specific products and transactions completed. The advisory fees vary based on the average daily balance of the managed assets for the period. The commissions and advisory fees represent variable consideration under FASB ASC Topic 606. Trustmark has elected the 'as-invoiced' practical expedient allowed under FASB ASC Topic 606 to recognize revenue from the investment services company.

***Derivative Financial Instruments***

Trustmark maintains an overall interest rate risk management strategy that incorporates the use of derivative instruments to minimize significant unplanned fluctuations in earnings and cash flows caused by interest rate volatility. Trustmark's interest rate risk management strategy involves modifying the repricing characteristics of certain assets and liabilities so that changes in interest rates do not adversely affect the net interest margin and cash flows. Under the guidelines of FASB ASC Topic 815, "Derivatives and Hedging," all derivative instruments are required to be recognized as either assets or liabilities and carried at fair value on the consolidated balance sheets. The fair value of derivative positions outstanding is included in other assets and/or other liabilities in the accompanying consolidated balance sheets and in the net change in these financial statement line items in the accompanying consolidated statements of cash flows as well as included in noninterest income in the accompanying consolidated statements of income and other comprehensive income (loss), net of tax in the accompanying consolidated statements of comprehensive income. Trustmark's interest rate derivative instruments are subject to master netting agreements, and therefore, eligible for offsetting in the consolidated balance sheets. Trustmark has elected to not offset any derivative instruments in its consolidated balance sheets.

*Derivatives Designated as Hedging Instruments*

FASB ASC Topic 815 provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity's financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments.

Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge.

When entering into a hedge transaction, Trustmark formally documents the relationship between the hedging instrument and the hedged item, as well as the risk management objective and strategy for undertaking the hedge transaction, which includes designating the derivative instrument as a fair value or cash flow hedge to a specific asset or liability on the consolidated balance sheets or to specific forecasted transactions and the risk being hedged, along with a formal assessment at the inception of the hedge as to the effectiveness

------

of the derivative instrument in offsetting changes in fair values or cash flows of the hedged item. Trustmark continues to assess hedge effectiveness on an ongoing basis using either a qualitative or a quantitative assessment (regression analysis).

As required by FASB ASC Topic 815, Trustmark records all derivatives on the consolidated balance sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether Trustmark has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. For cash flow hedges, changes in the fair value of the derivative instrument are recorded in accumulated other comprehensive income (loss) and subsequently reclassified to net income in the same period that the hedged transaction impacts net income. Upon discontinuation of hedge accounting for cash flow hedges, any amounts in accumulated other comprehensive income (loss) related to that relationship affects earnings at the same time and in the same manner in which the hedged transaction affects earnings. If it becomes probable that the forecasted transaction will not occur, any related amounts in accumulated other comprehensive income (loss) are reclassified to earnings immediately.

*Derivatives Not Designated as Hedging Instruments*

As part of Trustmark's risk management strategy in the mortgage banking area, derivative instruments such as forward sales contracts are utilized. Trustmark's obligations under forward contracts consist of commitments to deliver mortgage loans, originated and/or purchased, in the secondary market at a future date. Changes in the fair value of these derivative instruments are recorded as noninterest income in mortgage banking, net and are offset by changes in the fair value of LHFS. See Note 1 – Significant Accounting Policies, "LHFS" for information regarding the fair value option election.

Trustmark also utilizes derivative instruments such as interest rate lock commitments in its mortgage banking area. Rate lock commitments are residential mortgage loan commitments with customers, which guarantee a specified interest rate for a specified time period. Changes in the fair value of these derivative instruments are recorded as noninterest income in mortgage banking, net and are offset by the changes in the fair value of forward sales contracts.

Trustmark utilizes a portfolio of exchange-traded derivative instruments, such as Treasury note futures contracts and option contracts, to achieve a fair value return that economically hedges changes in the fair value of the MSR attributable to interest rates. These transactions are considered freestanding derivatives that do not otherwise qualify for hedge accounting. These exchange-traded derivative instruments are accounted for at fair value with changes in the fair value recorded as noninterest income in mortgage banking, net and are offset by changes in the fair value of the MSR. The MSR fair value represents the present value of future cash flows, which among other things includes decay and the effect of changes in interest rates. Ineffectiveness of hedging the MSR fair value is measured by comparing the change in the fair value of the hedge instruments to the change in the fair value of the MSR asset attributable to changes in interest rates and other market driven changes in valuation inputs and assumptions.

Trustmark offers certain derivatives products directly to qualified commercial lending clients seeking to manage their interest rate risk. Trustmark economically hedges interest rate swap transactions executed with commercial lending clients by entering into offsetting interest rate swap transactions with institutional derivatives market participants. Derivative transactions executed as part of this program are not designated as qualifying hedging relationships and are, therefore, carried at fair value with the change in fair value recorded as noninterest income in bank card and other fees. Because these derivatives have mirror-image contractual terms, in addition to collateral provisions which mitigate the impact of non-performance risk, the changes in fair value are expected to substantially offset. The offsetting interest rate swap transactions are either cleared through the Chicago Mercantile Exchange for clearable transactions or booked directly with institutional derivatives market participants for non-clearable transactions. The Chicago Mercantile Exchange rules legally characterize variation margin collateral payments made or received for centrally cleared interest rate swaps as settlements rather than collateral. As a result, centrally cleared interest rate swaps included in other assets and other liabilities are presented on a net basis in the accompanying consolidated balance sheets.

***Income Taxes***

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

------

***Stock-Based Compensation***

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

***Statements of Cash Flows***

For purposes of reporting cash flows, cash and cash equivalents include cash on hand and amounts due from banks. The following table reflects specific transaction amounts for the periods presented ($ in thousands):

---

| | | | |
|:---|:---|:---|:---|
|  | Years Ended December 31, | Years Ended December 31, | Years Ended December 31, |
|  | 2025 | 2024 | 2023 |
| Income taxes paid | $52165 | $21472 | $38803 |
| Interest paid on deposits and borrowings | 314753 | 385779 | 306568 |
| Noncash transfers from loans to other real estate | 8471 | 6782 | 7237 |
| Investment in tax credit partnership not funded |  | 4839 | 3202 |
| Operating right-of-use assets resulting from lease liabilities | 1745 | 1831 | 7303 |

---

***Per Share Data***

Trustmark accounts for per share data in accordance with FASB ASC Topic 260, "Earnings Per Share," which provides that unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of EPS pursuant to the two-class method. Trustmark has determined that its outstanding unvested stock awards are not participating securities and as a result are not included in the computation of basic EPS. Based on this determination, no change has been made to Trustmark's current computation for basic and diluted EPS.

Basic EPS is computed by dividing net income by the weighted-average shares of common stock outstanding. Diluted EPS is computed by dividing net income by the weighted-average shares of common stock outstanding, adjusted for the effect of potentially dilutive stock awards outstanding during the period.

The following table reflects weighted-average shares used to calculate basic and diluted EPS for the periods presented (in thousands):

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
|  | Years Ended December 31, | Years Ended December 31, | Years Ended December 31, | Years Ended December 31, | Years Ended December 31, | Years Ended December 31, |
|  | 2025 | 2025 | 2024 | 2024 | 2023 | 2023 |
| Basic shares |  | 60,310 |  | 61,158 |  | 61,054 |
| Dilutive shares |  | 232 |  | 226 |  | 177 |
| Diluted shares |  | 60,542 |  | 61,384 |  | 61,231 |

***Fair Value Measurements***

FASB ASC Topic 820, "Fair Value Measurements and Disclosures," defines fair value, establishes a framework for measuring fair value in GAAP, and requires certain disclosures about fair value measurements. The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. Depending on the nature of the asset or liability, Trustmark uses various valuation techniques and assumptions when estimating fair value. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. FASB ASC Topic 820 establishes a fair value hierarchy

------

for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

Level 1 Inputs – Valuation is based upon quoted prices (unadjusted) in active markets for identical assets or liabilities that Trustmark has the ability to access at the measurement date.

Level 2 Inputs – Valuation is based upon quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability such as interest rates, yield curves, volatilities and default rates and inputs that are derived principally from or corroborated by observable market data.

Level 3 Inputs – Unobservable inputs reflecting the reporting entity's own determination about the assumptions that market participants would use in pricing the asset or liability based on the best information available.

In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the fair value measurement in its entirety is classified is based on the lowest level input that is significant to the fair value measurement in its entirety. Trustmark's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer.

***Accounting Policies Recently Adopted***

Except for the changes detailed below, Trustmark has consistently applied its accounting policies to all periods presented in the accompanying consolidated financial statements.

*ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures."* Issued in December 2023, ASU 2023-09 is intended to improve the disclosures for income taxes to address requests from investors, lenders, creditors and other allocators of capital (collectively, "investors") that use the financial statements to make capital allocation decisions. During the FASB's 2021 agenda consultation process and other stakeholder outreach, investors highlighted that the current system of income tax disclosures does not provide enough information to understand the tax provision for an entity that operates in multiple jurisdictions. Investors currently rely on the rate reconciliation table and other disclosures, including total income taxes paid in the statement of cash flows, to evaluate income tax risks and opportunities. The amendments in ASU 2023-09 require consistent categories and greater disaggregation of information in the rate reconciliation disclosure as well as disclosure of income taxes paid disaggregated by jurisdiction. Trustmark adopted the amendments of ASU 2023-09 on a prospective basis effective January 1, 2025, and the newly required disclosures are included in Note 13 – Income Taxes of this report. Adoption of ASU 2023-09 did not have a material impact to Trustmark's consolidated financial statements or results of operations.

***Pending Accounting Pronouncements***

*ASU 2024-03, "Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses."* Issued in November 2024, ASU 2024-03 with the objective of providing investors with more decision-useful information regarding a public business entity's expenses by enhancing disclosures on income statement expenses. Investor feedback indicated a strong preference for the disclosure of disaggregated financial reporting information as a top priority for the FASB. Detailed knowledge of an entity's expenses is crucial for understanding its prospects for future cash flows and for making performance comparisons over time and with other entities. Investors emphasized that information regarding cost of sales, selling, general, and administrative expenses, employee compensation costs, depreciation and amortization, and research and development expenditure would enhance their comprehension of an entity's cost structure and ability to forecast future cash flows. The ASU applies exclusively to public business entities and mandates additional disclosures about specific expense categories on both annual and interim bases in the notes to financial statements that are not currently required. The amendments do not alter or eliminate existing expense disclosure requirements nor change requirements for presenting expenses on the face of the income statement. However, they do specify that certain existing disclosures must now appear in the same tabular format as the new disaggregation requirements. The FASB issued ASU 2025-01 in January 2025, clarifying that the amendments in ASU 2024-03 are effective for public business entities for annual reporting periods beginning after December 15, 2026, and for interim reporting periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. Trustmark intends to adopt the amendments of ASU 2024-03 effective January 1, 2027, and will include the required annual disclosures in its Annual Report on Form 10-K for the year ending December 31, 2027, and required interim disclosures in its Quarterly Report on Form 10-Q for the period ending March 31, 2028. Trustmark is currently evaluating the changes to disclosures required by ASU 2024-03; however, adoption of ASU 2024-03 is not expected to have a material impact to Trustmark's consolidated financial statements or results of operations.

------

*ASU 2025-06, "Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software."* Issued in September 2025, ASU 2025-06 seeks to update the guidance on accounting for software due to changes in how software is generally developed. When software accounting guidance was first issued, companies developing software generally followed a prescriptive and sequential development method (*e.g.*, waterfall). Since then, many companies have adopted a more incremental and iterative development method (*i.e.*, agile). As a result, many stakeholders noted the challenges of applying current internal-use software accounting requirements that do not specifically address software developed using an incremental and iterative method, which has led to diversity in practice in determining when to begin capitalizing software costs. The amendments of ASU 2025-06 remove all references to a prescriptive and sequential software development method (referred to as "project stages") throughout FASB ASC Subtopic 350-40, and require an entity to start capitalizing software costs when both of the following occur: (1) Management has authorized and committed to funding the software project; and (2) it is probable that the project will be completed and the software will be used to perform the function intended (referred to as the "probable-to-complete recognition threshold"). In evaluating the probable-to-complete recognition threshold, a company is required to consider whether there is significant uncertainty associated with the development activities of the software. ASU 2025-06 is effective for all entities for annual reporting periods beginning after December 15, 2027, and for interim reporting periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. Trustmark intends to adopt the amendments of ASU 2025-06 effective January 1, 2028. Trustmark is currently evaluating the impact the amendments of ASU 2025-06 will have in regards to its internal-use software; however, adoption of ASU 2025-06 is not expected to have a material impact to Trustmark's consolidated financial statements or results of operations.

*ASU 2025-08, "Financial Instruments—Credit Losses (Topic 326): Purchased Loans."* Issued in November 2025, ASU 2025-08 expands the gross-up approach for accounting for credit losses on acquired financial assets, addressing complexity and comparability issues caused by previous distinctions between purchased financial assets with credit deterioration (PCD assets) and non-PCD assets. ASU 2025-08 requires loans (excluding credit cards) acquired without significant credit deterioration and deemed "seasoned" to be accounted for using the gross-up approach. For these purchased seasoned loans (loans, excluding credit cards, debt securities and trade receivables, acquired through a business combination accounted for using the acquisition method or other loans acquired through transfers not accounted for as business combinations purchased at least 90 days after origination and not originated by the acquirer), the initial ACL is added to the purchase price to determine the amortized cost basis. Entities can elect to measure this ACL using the amortized cost basis if not employing a discounted cash flow method, with elections being irrevocable. ASU 2025-08 clarifies that purchased seasoned loans are subject to the same accrual policies as originated assets and are not subject to the guidance that permits interest income accrual on PCD assets when there is a reasonable expectation for amounts to be collected or recovery limitations. ASU 2025-08 also amends disclosure requirements for the rollforward of the ACL to present the initial allowance recognized on such loans separately. ASU 2025-08 is effective for annual periods after December 15, 2026, and for interim reporting periods within those annual reporting periods, with early adoption allowed and prospective application required. Trustmark intends to adopt the amendments of ASU 2025-08 on January 1, 2027; however, as the amendments of this ASU must be applied on a prospective basis, adoption of this ASU will have no impact to Trustmark's consolidated financial statements or results of operations until an acquisition occurs.

*ASU 2025-09, "Derivatives and Hedging (Topic 815): Hedge Accounting Improvements."* Issued in November 2025, ASU 2025-09 updates hedge accounting guidance to address global reference rate reform and better align hedge accounting with entities' risk management practices. Key changes include broadening eligible hedged risks for cash flow hedges via a "similar risk exposure" test, introducing an optional operable model for hedge accounting on choose-your-rate debt instruments, permitting hedge accounting for forecasted spot and forward transactions in nonfinancial assets if price components are clearly related and removing the net written option test for certain derivatives. The amendments of ASU 2025-09 also resolve recognition mismatches in dual hedge strategies involving foreign-currency-denominated debt. The amendments of ASU 2025-09 are effective for annual reporting periods beginning after December 15, 2026, and for interim reporting periods within those annual reporting periods, and should be applied on a prospective basis for all hedging relationships. Early adoption is permitted. Entities may also modify certain critical terms of existing hedging relationships without de-designating the hedge upon adoption. Trustmark intends to adopt the amendments of ASU 2025-09 effective January 1, 2027. Trustmark is currently evaluating the impact the amendments of ASU 2025-09 will have in regard to its derivative and hedging instruments; however, adoption of ASU 2025-09 is not expected to have a material impact to Trustmark's consolidated financial statements or results of operations.

**N**ote 2 - Discontinued Operations

On May 31, 2024, TB completed the sale of its wholly owned subsidiary, Fisher Brown Bottrell Insurance, Inc. (FBBI), to Marsh & McLennan Agency LLC for $336.9 million in cash. The transaction resulted in a pre-tax net gain of $228.3 million. The gain, along with FBBI's historical financial results for the periods prior to the sale, is reflected in Trustmark's consolidated financial statements as discontinued operations. FBBI's operating results prior to the sale have been presented as "Income from Discontinued Operations" within the accompanying consolidated statements of income for the years ended December 31, 2024 and 2023. Cash flows from both continuing and discontinued operations are included in the accompanying consolidated statements of cash flows for the years ended December 31, 2024 and 2023.

------

During 2022, Trustmark reclassified a total of $766.0 million of securities available for sale to securities held to maturity. On the date of these transfers, the net unrealized holding loss on the available for sale securities totaled approximately $91.9 million ($68.9 million, net of tax).

The securities were transferred at fair value, which became the cost basis for the securities held to maturity. The net unrealized holding loss will be amortized over the remaining life of the securities as a yield adjustment in a manner consistent with the amortization or accretion of the original purchase premium or discount on the associated security. There were no gains or losses recognized as a result of these transfers. At December 31, 2025, the net unamortized, unrealized loss on transferred securities included in accumulated other comprehensive income (loss) in the accompanying consolidated balance sheets totaled $36.3 million compared to $46.6 million at December 31, 2024.

***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 December 31, 2025 and 2024, the results of the loss analysis performed did not identify any securities that warranted DCF analysis and no credit loss was recognized on any of the securities available for sale.

Accrued interest receivable is excluded from the estimate of credit losses for securities available for sale. At December 31, 2025 and 2024, accrued interest receivable totaled $5.9 million and $5.0 million, respectively, for securities available for sale and was reported in other assets on the accompanying consolidated balance sheets.

*Securities Held to Maturity*

At both December 31, 2025 and 2024, Trustmark identified no securities held to maturity with the potential for credit loss exposure. After applying appropriate probability of default (PD) and loss given default (LGD) assumptions, the total amount of current expected credit losses was zero at both December 31, 2025 and 2024. Therefore, no reserve was recorded at either December 31, 2025 or December 31, 2024.

Accrued interest receivable is excluded from the estimate of credit losses for securities held to maturity. At December 31, 2025 and 2024, accrued interest receivable totaled $2.1 million and $2.4 million, respectively, for securities held to maturity and was reported in other assets on the accompanying consolidated balance sheets.

At both December 31, 2025 and 2024, Trustmark had no securities held to maturity that were past due 30 days or more as to principal or interest payments. Trustmark had no securities held to maturity classified as nonaccrual at December 31, 2025 and 2024.

Trustmark monitors the credit quality of securities held to maturity on a monthly basis through credit ratings. The following table presents the amortized cost of Trustmark's securities held to maturity by credit rating, as determined by Moody's, at December 31, 2025 and 2024 ($ in thousands):

---

| | | |
|:---|:---|:---|
|  | December 31, | December 31, |
|  | 2025 | 2024 |
| Aaa | $52405 | $1335385 |
| Aa1 to Aa3 | 1155049 |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Total | $1207454 | $1335385 |

---

During 2025, a significant portion of Trustmark's investment portfolio moved from the Aaa credit rating to the Aa1 to Aa3 credit rating. The change in the credit rating of Trustmark's investment portfolio was the result of Moody's downgrade of the United States' credit rating from Aaa to Aa1 during the second quarter of 2025. The downgrade was primarily due to concerns about the rising federal debt, increasing interest costs and a perceived weakening of the government's ability to respond to future economic shocks.

The unrealized losses shown above were due to increases in market rates over the yields available at the time of purchase of the underlying securities and not credit quality. Trustmark does not intend to sell these securities and it is more likely than not that Trustmark will not be required to sell the investments before recovery of their amortized cost bases, which may be at maturity.

***Securities Gains and Losses***

Realized gains and losses are determined using the specific identification method and are included in noninterest income (loss) as securities gains (losses), net. For the periods presented, gross realized gains or losses as a result of calls and dispositions of securities, as well as any associated proceeds, were as follows ($ in thousands):

During the second quarter of 2024, Trustmark restructured its investment securities portfolio by selling $1.561 billion of available for sale securities with an average yield of 1.36%, which generated a loss of $182.8 million ($137.1 million, net of taxes) and was recorded to noninterest income (loss) in securities gains (losses), net. Proceeds from the sale were used to purchase $1.378 billion of available for sale securities with an average yield of 4.85%.

***Securities Pledged***

Securities with a carrying value of $1.709 billion and $1.910 billion at December 31, 2025 and 2024, respectively, were pledged to collateralize public deposits and securities sold under repurchase agreements and for other purposes as permitted by law. At both December 31, 2025 and 2024, none of these securities were pledged under the Federal Reserve Discount Window program to provide additional contingency funding capacity.

***Contractual Maturities***

The amortized cost and estimated fair value of securities available for sale and held to maturity at December 31, 2025, 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.

***Loan Concentrations***

Trustmark does not have any loan concentrations other than those reflected in the preceding table, which exceed 10% of total LHFI. At December 31, 2025, Trustmark's geographic loan distribution was concentrated primarily in its six key market regions: Alabama, Florida, Georgia, Mississippi, Tennessee and Texas. Accordingly, the ultimate collectability of a substantial portion of these loans is susceptible to changes in market conditions in these areas.

***Related Party Loans***

At December 31, 2025 and 2024, loans to certain executive officers and directors, including their immediate families and companies in which they are principal owners, totaled $31.4 million and $33.1 million, respectively. During 2025, $310.0 million of new loan advances were made, while repayments were $307.7 million. In addition, decreases in loans due to changes in executive officers and directors totaled $4.1 million during 2025.

***Nonaccrual and Past Due LHFI***

No material interest income was recognized in the income statement on nonaccrual LHFI for each of the years in the three-year period ended December 31, 2025.

***Modified LHFI***

Occasionally, Trustmark modifies loans for borrowers experiencing financial difficulty by providing payment delays, interest-only payments for an extended period of time, maturity extensions or interest rate reductions. Other concessions may arise from court proceedings or may be imposed by law. In some cases, Trustmark provides multiple types of concessions on one loan.

The following tables present the amortized cost of LHFI of loans modified to borrowers experiencing financial difficulty disaggregated by class of loan and type of modification at the end of each of the periods presented ($ in thousands). The percentage of the amortized cost basis of LHFI that were modified to borrowers experiencing financial difficulty as compared to the amortized cost basis of each class of LHFI is also presented below:

Trustmark had no unused commitments on modified loans to borrowers experiencing financial difficulty at December 31, 2025 or December 31, 2024.

For all loans modified in the previous twelve months to borrowers experiencing financial difficulty, Trustmark had payment defaults during the year ended December 31, 2025 on $578 thousand of loans in the commercial and industrial loans portfolio that had received payment delay modifications and $78 thousand of loans in the other secured by 1-4 family residential properties portfolio and $2.1 million of loans in the secured by 1-4 family residential properties portfolio that had received term extension modifications. During the year ended December 31, 2024, Trustmark had $6.2 million of loans in the commercial and industrial loans portfolio that had received payment delay modifications and $70 thousand of loans in the other secured by 1-4 family residential properties portfolio that had received term extension modifications. During the year ended December 31, 2023, Trustmark had $116 thousand of loans in the other commercial loans and leases portfolio that had received payment delay modifications.

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 in the preceding twelve months as of December 31, 2025, 2024 and 2023 ($ in thousands):

A loan is collateral dependent when the borrower is experiencing financial difficulty and repayment of the loan is expected to be provided substantially through the sale of the collateral. The following provides a qualitative description by class of loan of the collateral that secures Trustmark's collateral-dependent LHFI:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Commercial and industrial loans – Loans within this loan class are primarily secured by inventory, accounts receivables, equipment and other non-real estate collateral. There have been no significant changes to the collateral that secures these financial assets during the period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Consumer loans – Loans within this loan class are secured by liens on real estate properties or other non-real estate collateral. There was one credit that had deterioration in real estate collateral during the quarter. There were no other significant changes to the collateral that secures these financial assets during the period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Other commercial loans and leases – Loans and leases within this loan class are secured by non-real estate collateral. There have been no significant changes to the collateral that secures these financial assets during the period.

***Credit Quality Indicators***

Trustmark's LHFI portfolio credit quality indicators focus on six key quality ratios that are compared against bank tolerances. The loan indicators are total classified outstanding, total criticized outstanding, nonperforming loans, nonperforming assets, delinquencies and net loan losses. Due to the homogeneous nature of consumer loans, Trustmark does not assign a formal internal risk rating to each credit and therefore the criticized and classified measures are primarily composed of commercial loans.

In addition to monitoring portfolio credit quality indicators, Trustmark also measures how effectively the lending process is being managed and risks are being identified. As part of an ongoing monitoring process, Trustmark grades the commercial portfolio segment as it relates to credit file completion and financial statement exceptions, underwriting, collateral documentation and compliance with law as shown below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Loss (RR 10) – a loan or a portion of a loan that is deemed to be uncollectible.

By definition, credit risk grades special mention (RR 7), substandard (RR 8), doubtful (RR 9) and loss (RR 10) are criticized loans while substandard (RR 8), doubtful (RR 9) and loss (RR 10) are classified loans. These definitions are standardized by all bank regulatory agencies and are generally equally applied to each individual lending institution. The remaining credit risk grades are considered pass credits and are solely defined by Trustmark.

To enhance this process, Trustmark has determined that certain loans will be individually assessed, and a formal analysis will be performed and based upon the analysis the loan will be written down to the net realizable value. Trustmark will individually assess and remove loans from the pool in the following circumstances:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Commercial accruing loans deemed to be a modified loan to a borrower experiencing financial difficulty with total exposure of $500 thousand (excluding those portions of the debt that are government guaranteed or are secured by Trustmark deposits or marketable securities) or more. If the loan is believed to not share similar risk characteristics with the rest of the loan pool, the loan will be individually assessed. Otherwise, the loan will be left within the pool and monitored on an ongoing basis.

Each loan officer assesses the appropriateness of the internal risk rating assigned to their credits on an ongoing basis. Trustmark's Asset Review area conducts independent credit quality reviews of the majority of Trustmark's commercial loan portfolio both on the underlying credit quality of each individual loan class as well as the adherence to Trustmark's loan policy and the loan administration process.

In addition to the ongoing internal risk rate monitoring described above, Trustmark's Credit Quality Review Committee meets monthly and performs a review of all loans of $100 thousand or more that are either delinquent 30 days or more or on nonaccrual. This review includes recommendations regarding risk ratings, accrual status, charge-offs and appropriate servicing officer as well as evaluation of

------

problem credits for determination of modified status. Quarterly, the Credit Quality Review Committee reviews and modifies continuous action plans for all credits risk rated seven or worse for relationships of $250 thousand or more.

In addition, periodic reviews of significant development, construction, multi-family, nonowner-occupied and other commercial credits are performed. These reviews assess each particular project with respect to location, project valuations, progress of completion, leasing status, current financial information, rents, operating expenses, cash flow, adherence to budget and projections and other information that is pertinent to the particular type of credit as applicable. Summary results are reviewed by Senior and Regional Credit Officers in addition to the Chief Credit and Operations Officer with a determination made as to the appropriateness of existing risk ratings and accrual status.

*Consumer Credits*

The Retail Credit Review Committee, Management Credit Policy Committee and the Enterprise Risk Committee review the volume and percentage of consumer loan delinquencies and losses to monitor the overall quality of the consumer portfolio.

Trustmark monitors the levels and severity of past due consumer LHFI on a daily basis through its collection activities. A detailed assessment of consumer LHFI delinquencies is performed monthly at both a product and market level.

***Past Due LHFS***

LHFS past due 90 days or more totaled $98.9 million and $71.3 million at December 31, 2025 and 2024, respectively.

------

Trustmark did not exercise its buy-back option on any delinquent loans serviced for GNMA during 2025 or 2024.

***ACL on LHFI***

Trustmark's ACL methodology for LHFI is based upon guidance within FASB ASC Subtopic 326-20 as well as applicable regulatory guidance. The ACL is a valuation account that is deducted from the loans' amortized cost basis to present the net amount expected to be collected on the loans. Credit quality within the LHFI portfolio is continuously monitored by Management and is reflected within the ACL for LHFI. The ACL is an estimate of expected losses inherent within Trustmark's existing LHFI portfolio. The ACL for LHFI is adjusted through the PCL, LHFI and reduced by the charge off of loan amounts, net of recoveries.

The methodology for estimating the amount of expected credit losses reported in the ACL has two basic components: a collective, or pooled, component for estimated expected credit losses for pools of loans that share similar risk characteristics, and an asset-specific component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans. In estimating the ACL for the collective component, loans are segregated into loan pools based on loan product types and similar risk characteristics.

The loans secured by real estate and other loans secured by real estate portfolio segments include loans for both commercial and residential properties. The underwriting process for these loans includes analysis of the financial position and strength of both the borrower and guarantor, experience with similar projects in the past, market demand and prospects for successful completion of the proposed project within the established budget and schedule, values of underlying collateral, availability of permanent financing, maximum loan-to-value ratios, minimum equity requirements, acceptable amortization periods and minimum debt service coverage requirements, based on property type. The borrower's financial strength and capacity to repay their obligations remain the primary focus of underwriting. Financial strength is evaluated based upon analytical tools that consider historical and projected cash flows and performance in addition to analysis of the proposed project for income-producing properties. Additional support offered by guarantors is also considered. Ultimate repayment of these loans is sensitive to interest rate changes, general economic conditions, liquidity and availability of long-term financing.

The commercial and industrial loans portfolio segment includes loans 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 loans portfolio segment is comprised of loans that are centrally underwritten based on the borrower's credit bureau score as well as an evaluation of the borrower's repayment capacity, credit, and collateral. Property appraisals are obtained to assist in evaluating collateral. Loan-to-value and debt-to-income ratios, loan amount, and lien position are also considered in assessing whether to originate a loan. These borrowers are particularly susceptible to downturns in economic trends such as conditions that negatively affect housing prices and demand and levels of unemployment.

The state and other political subdivision loans and the other commercial loans portfolio segments primarily consist of loans to non-depository financial institutions, such as mortgage companies, finance companies and other financial intermediaries, loans to state and political subdivisions, and loans to non-profit and charitable organizations. These loans are underwritten based on the specific nature or purpose of the loan and underlying collateral with special consideration given to the specific source of repayment for the loan. The commercial leases portfolio segment primarily consists of commercial equipment finance leases. Trustmark's credit underwriting process for equipment finance leases includes analysis of historical and projected cash flows and performance, evaluation of financial strength of both borrowers and guarantors as reflected in current and detailed financial information and evaluation of underlying collateral to support the credit.

During the first quarter of 2025, as part of Trustmark's ongoing model monitoring procedures, the annual loss driver analysis was performed. The analysis resulted in changes in the loss drivers for four discounted cash flow models. These changes were a result of incorporating data through 2024 which led to more intuitive loss drivers. All models were validated by a third-party before implementation.

During the first quarter of 2024, as part of Trustmark's ongoing model monitoring procedures, the annual loss driver analysis was performed. The analysis resulted in changes in the loss drivers for all discounted cash-flow models along with changes in the loss drivers for the equipment and finance loans and leases model. These changes were a result of updating Trustmark's peer group and incorporating data through 2022 which led to more intuitive loss drivers. All models were validated by a third party before implementation.

In general, Trustmark utilizes a DCF method to estimate the quantitative portion of the ACL for loan pools. The DCF model consists of two key components, a loss driver analysis (LDA) and a cash flow analysis. For loan pools utilizing the DCF methodology, multiple

------

assumptions are in place, depending on the loan pool. A reasonable and supportable forecast is utilized for each loan pool by developing a LDA for each loan class. The LDA uses charge off data from Federal Financial Institutions Examination Council (FFIEC) reports to construct a periodic default rate (PDR). The PDR is decomposed into a PD. Regressions are run using the data for various macroeconomic variables in order to determine which ones correlate to Trustmark's losses. These variables are then incorporated into the application to calculate a quarterly PD using a third-party baseline forecast. In addition to the PD, a LGD is derived using a method referred to as Frye-Jacobs. The Frye-Jacobs method is a mathematical formula that traces the relationship between LGD and PD over time and projects the LGD based on the levels of PD forecasts. This model approach is applicable to all pools within the construction, land development and other land, other secured by 1-4 family residential properties, secured by nonfarm, nonresidential properties and other real estate secured loan classes as well as consumer loans and other commercial loans.

An alternative LDA is utilized 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. Management believes this methodology 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 weighted average remaining maturity (WARM) method, the remaining life is incorporated into the ACL quantitative calculation.

During the second quarter of 2024, Trustmark executed a sale on a portfolio of 1-4 family mortgage loans that were at least three payments delinquent and/or nonaccrual at the time of selection. As a result of this sale, a credit mark was established for a sub-pool of the loans in the sale. Due to the lack of historical experience and the use of industry data for this sub-pool, management elected to use the credit mark for reserving purposes on a go forward basis for this sub-pool that meets the same credit criteria of being three payments delinquent and/or nonaccrual. All loans of the sub-pool that meet the above credit criteria will be removed from the 1-4 family residential properties pool and placed into a separate pool with the credit mark reserve applied to the total balance.

Trustmark determined that reasonable and supportable forecasts could be made for a twelve-month period for all of its loan pools. To the extent the lives of the loans in the LHFI portfolio extend beyond this forecast period, Trustmark uses a reversion period of four quarters and reverts to the historical mean on a straight-line basis over the remaining life of the loans. The econometric models currently in production reflect segment or pool level sensitivities of PD to changes in macroeconomic variables. By measuring the relationship between defaults and changes in the economy, the quantitative reserve incorporates reasonable and supportable forecasts of future conditions that will affect the value of Trustmark's assets, as required by FASB ASC Topic 326. Under stable forecasts, these linear regressions will reasonably predict a pool's PD. However, upon the occurrence of events that generate significant economic instability (such as the COVID-19 pandemic), the macroeconomic variables used for reasonable and supportable forecasting can change rapidly. At the macroeconomic levels experienced during the COVID-19 pandemic, it was not clear that the models in production at that time would produce reasonably representative results since the models at that time were originally estimated using data beginning in 2004 through 2019. During this period, a traditional, albeit severe, economic recession occurred. Thus, econometric models are sensitive to similar future levels of PD.

In order to prevent the econometric models from extrapolating beyond reasonable boundaries of their input variables, Trustmark chose to establish an upper and lower limit process when applying the periodic forecasts. In this way, Management will not rely upon unobserved and untested relationships in the setting of the quantitative reserve. This approach applies to all input variables, including: Southern Unemployment, National Unemployment, National Gross Domestic Product (GDP), National Home Price Index (HPI), National Commercial Real Estate (CRE) Price Index and the BBB 7-10 Year US Corporate Bond Index (CBI). The upper and lower limits are based on the distribution of the macroeconomic variable by selecting extreme percentiles at the upper and lower limits of the distribution, the 1<sup>st</sup>and 99<sup>th</sup>percentiles, respectively. These upper and lower limits are then used to calculate the PD for the forecast

------

time period in which the forecasted values are outside of the upper and lower limit range. Additionally, when periods have a PD or LGD at or near zero as a result of the improving macroeconomic forecasts, Management implemented PD and LGD floors to account for the risk associated with each portfolio. The PD and LGD floors are based on Trustmark's historical loss experience and applied at a portfolio level.

Qualitative factors used in the ACL methodology include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Lending policies and procedures

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Economic conditions and concentrations of credit

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Nature and volume of the portfolio

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Performance trends

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•External factors

While all these factors are incorporated into the overall methodology, only three are currently considered active at December 31, 2025: (i) economic conditions and concentrations of credit, (ii) nature and volume of the portfolio and (iii) performance trends.

Two of Trustmark's largest loan classes are the loans secured by nonfarm, nonresidential properties and the loans secured by other real estate. Trustmark elected to create a qualitative factor specifically for these loan classes which addresses changes in the economic conditions of metropolitan areas and applies additional pool level reserves. This qualitative factor is based on third-party market data and forecast trends and is updated quarterly as information is available, by market and by loan pool.

Trustmark's current quantitative methodologies do not completely incorporate changes in credit quality. As a result, Trustmark utilizes the performance trends qualitative factor. This factor is based on migration analyses, that allocates additional ACL to non-pass/delinquent loans within each pool. In this way, Management believes the ACL will directly reflect changes in risk, based on the performance of the loans within a pool, whether declining or improving.

The performance trends qualitative factor is estimated by properly segmenting loan pools into risk levels by risk rating for commercial credits and delinquency status for consumer credits. A migration analysis is then performed quarterly using a third-party software and the results for each risk level are compiled to calculate the historical PD average for each loan portfolio based on risk levels. This average historical PD rate is updated annually. For the mortgage portfolio, Trustmark uses an internal report to incorporate a roll rate method for the calculation of the PD rate. In addition to the PD rate for each portfolio, Management incorporates the quantitative rate and the k value derived from the Frye-Jacobs method to calculate a loss estimate that includes both PD and LGD. The quantitative rate is used to eliminate any additional reserve that the quantitative reserve already includes. Finally, the loss estimate rate is then applied to the total balances for each risk level for each portfolio to calculate a qualitative reserve.

The nature and volume of the portfolio qualitative factor is utilized for a sub-pool of the secured by 1-4 family residential properties due to its significant size as well as the underlying nature being different. The nature and volume of the portfolio qualitative factor utilizes a WARM methodology that uses industry data for the assumptions to support the qualitative adjustment. The industry data is used to compile a PD based on credit score ranges along with using the industry data to compile an LGD. The sub-pool of credits is then aggregated into the appropriate credit score bands in which a weighted average loss rate is calculated based on the PD and LGD for each credit score range. This weighted average loss rate is then applied to the expected balance for the sub-segment of credits. This total is then used as the qualitative reserve adjustment. During the first quarter of 2025, Management elected to utilize Trustmark's historical data to develop a PD based on the credit score ranges initially established. Additionally, Management elected to use the same LGD value from the mortgage sale that occurred in the second quarter of 2024 along with the same weighted average life assumption utilized to determine the credit mark on this portfolio.

The external factors qualitative factor is Management's best judgment on the loan or pool level impact of all factors that affect the portfolio that are not accounted for using any other part of the ACL methodology (*e.g.*, natural disasters, changes in legislation, impacts due to technology and pandemics). During the third quarter of 2024, Trustmark activated the External Factor – Credit Quality Review qualitative factor. This qualitative factor ensures reserve adequacy for collectively evaluated commercial loans that may not have been identified and downgraded timely for various reasons. This qualitative factor population is all commercial loans risk rated 1-5. These loans are then applied to the historical average of the Watch/Special Mention rated percentage. Then the balance of these loans are applied additional reserves based on the same reserve rates utilized in the performance trends qualitative factor for Watch/Special Mention rated loans. Then the Watch/Special Mention population is applied the historical Substandard rated percentage and then subsequently applied the Substandard reserve rate utilized in the performance trends qualitative factor as well. The historical Watch/Special Mention and Substandard rated percentage averages captures the weighted average life of the commercial loan portfolio.

------

Thus, Trustmark will allocate additional reserves to capture the proportion of potential Watch/Special Mention and Substandard rated credits that may not have been categorized as such at any given point in time through the life of the commercial loan portfolio.

During the third quarter of 2025, Management determined that the risk related to delayed identification and downgrading of commercial loans had sufficiently diminished and, as a result, resolved the External Factor – Credit Quality Review qualitative factor and released the associated reserves.

The PCL, LHFI for the year ended December 31, 2024 was primarily attributable to loan growth, changes in the macroeconomic forecast, an increase in specific reserves on individually analyzed credits and net adjustments to the qualitative factors.

The negative PCL, LHFI for the construction, land development and other land portfolio and other secured by 1-4 family residential properties portfolio for the year ended December 31, 2024 was primarily due to changes in the macroeconomic forecast associated with these specific loss driver models as a result of the loss driver update for these loan portfolios. The negative PCL, LHFI for the other commercial loans and leases portfolio for the year ended December 31, 2024 was primarily due to a decrease in loan balances.

Depreciation and amortization of premises and equipment totaled $18.8 million in 2025, $18.7 million in 2024 and $17.4 million in 2023.

**Note 6 – Mortgage Banking**

***MSR***

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

---

| | | |
|:---|:---|:---|
|  | Years Ended December 31, | Years Ended December 31, |
|  | 2025 | 2024 |
| Balance at beginning of period | $139317 | $131870 |
| Origination of servicing assets | 15052 | 13291 |
| Change in fair value: |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Due to market changes | (9840) | 5801 |
| &nbsp;&nbsp;&nbsp;&nbsp;Due to runoff | (13240) | (11645) |
| Balance at end of period | $131289 | $139317 |

---

Trustmark determines the fair value of the MSR using a valuation model administered by a third party that calculates the present value of estimated future net servicing income. Trustmark considers the conditional prepayment rate (CPR), which is an estimated loan prepayment rate that uses historical prepayment rates for previous loans similar to the loans being evaluated, the float rate, which is the interest rate earned on escrow balances, and the discount rate as some of the primary assumptions used in determining the fair value of the MSR. An increase in either the CPR or discount rate assumption will result in a decrease in the fair value of the MSR, while a decrease in either assumption will result in an increase in the fair value of the MSR. An increase in the float rate will result in an increase in the fair value of the MSR, while a decrease in the float rate will result in a decrease in the fair value of the MSR. At December 31, 2025, the fair value of the MSR included an assumed average prepayment speed of 9 CPR and an average discount rate of 10.66% compared to an assumed average prepayment speed of 8 CPR and an average discount rate of 10.65% at December 31, 2024.

***Mortgage Loans Sold/Serviced***

During 2025, 2024 and 2023, Trustmark sold $1.158 billion, $1.141 billion and $1.136 billion, respectively, of residential mortgage loans. Gain on sales of loans, net totaled $20.0 million in 2025, $19.3 million in 2024 and $15.3 million in 2023. Trustmark receives annual servicing fee income approximating 0.32% of the outstanding balance of the underlying loans, which totaled $28.7 million in 2025, $28.0 million in 2024 and $26.9 million in 2023. The gains on the sale of residential mortgage loans and the annual servicing fee are both recorded to noninterest income in mortgage banking, net in the accompanying consolidated statements of income. The investors and the securitization trusts have no recourse to the assets of Trustmark for failure of debtors to pay when due.

The table below details the mortgage loans sold and serviced for others at December 31, 2025 and 2024 ($ in thousands):

---

| | | |
|:---|:---|:---|
|  | December 31, | December 31, |
|  | 2025 | 2024 |
| Federal National Mortgage Association | $4745556 | $4821246 |
| Government National Mortgage Association | 3872151 | 3695419 |
| Federal Home Loan Mortgage Corporation | 314383 | 213358 |
| Other | 23872 | 32686 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total mortgage loans sold and serviced for others | $8955962 | $8762709 |

---

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 expense is included in other expense. Trustmark had no mortgage loan servicing putback expense during 2025, 2024 or 2023. At both December 31, 2025 and 2024, Trustmark had a reserve for mortgage loan servicing putback expenses of $500 thousand.

There is inherent uncertainty in reasonably estimating the requirement for reserves against potential future mortgage loan servicing putback expenses. Future putback expenses are dependent on many subjective factors, including the review procedures of the purchasers and the potential refinance activity on loans sold with servicing released and the subsequent consequences under the representations and warranties. Trustmark believes that it has appropriately reserved for potential mortgage loan servicing putback requests.

**Note 7 – Goodwill and Identifiable Intangible Assets**

***Goodwill***

The table below illustrates goodwill by segment for the years ended December 31, 2025 and 2024 ($ in thousands):

Trustmark's General Banking Segment delivers a full range of banking services to consumer, corporate, small and middle-market businesses through its extensive branch network. Trustmark performed goodwill impairment tests for the General Banking Segment during 2025, 2024 and 2023. Based on these tests, Trustmark concluded that the fair value of the General Banking Segment exceeded the book value and no impairment charge was required.

***Identifiable Intangible Assets***

---

------

Trustmark recorded $126 thousand of amortization of identifiable intangible assets in 2025, $110 thousand in 2024 and $290 thousand in 2023. Trustmark estimates that there will be no amortization expense for identifiable intangible assets in 2026 or the following years. Trustmark continually evaluates whether events and circumstances have occurred that indicate that identifiable intangible assets have become impaired. Measurement of any impairment of such identifiable intangible assets is based on the fair values of those assets. There were no impairment losses on identifiable intangible assets recorded during 2025, 2024 or 2023.

**Note 8 – Other Real Estate**

At December 31, 2025, Trustmark's geographic other real estate distribution was primarily concentrated in its Alabama, Mississippi Tennessee and Texas market regions.

The 2020 Notes were sold at an underwriting discount of 1.2%, resulting in net proceeds to Trustmark of $123.5 million before deducting offering expenses. At December 31, 2024, the carrying amount of the 2020 Notes was $123.7 million. The 2020 Notes qualified as Tier 2 capital for Trustmark.

During the fourth quarter of 2025, Trustmark issued and sold $175.0 million aggregate principal amount of its 6.00% Fixed-to-Floating Rate Subordinated Notes (the 2025 Notes) due December 1, 2035. The 2025 Notes were sold at an underwriting discount of 1.1%, resulting in net proceeds to Trustmark of $173.1 million before deducting offering expenses. Trustmark used the net proceeds from the offering, after the payment of offering expenses, to repay the $125.0 million of aggregate principal amount of the 2020 Notes plus accrued interest and for general corporate purposes.

The 2025 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 2025 Notes are obligations of Trustmark only and are not obligations of, and are not guaranteed by, any of its subsidiaries, including TB. The 2025 Notes qualify as Tier 2 capital for Trustmark. The 2025 Notes may be redeemed at Trustmark's option under certain circumstances.

From and including the date of issuance to, but excluding, December 1, 2030 (unless redeemed prior to such date), the 2025 Notes bear interest at a rate of 6.00% per year, payable semiannually in arrears on June 1 and December 1 of each year, commencing on June 1, 2026.

***Junior Subordinated Debt Securities***

On August 18, 2006, Trustmark completed a private placement of $60.0 million of trust preferred securities through a newly formed Delaware trust affiliate, Trustmark Preferred Capital Trust I (the Trust). The trust preferred securities mature September 30, 2036, are redeemable at Trustmark's option and bear interest at a variable rate per annum equal to the three-month Chicago Mercantile Exchange, Inc. (CME) SOFR plus a spread adjustment of 0.26% and a margin of 1.72%. Under applicable regulatory guidelines, these trust preferred securities qualify as Tier 1 capital. The proceeds from the sale of the trust preferred securities were used by the Trust to purchase $61.9 million in aggregate principal amount of Trustmark's junior subordinated debentures.

The debentures were issued pursuant to a Junior Subordinated Indenture, dated August 18, 2006, between Trustmark, as issuer, and Wilmington Trust Company, National Association, as trustee. Like the trust preferred securities, the debentures bear interest at a variable rate per annum equal to the three-month CME SOFR plus a spread adjustment of 0.26% and a margin of 1.72% and mature on September 30, 2036. The debentures may be redeemed at Trustmark's option at any time. The interest payments by Trustmark will be used to pay the quarterly distributions payable by the Trust to the holder of the trust preferred securities. However, so long as no event of default has occurred under the debentures, Trustmark may defer interest payments on the debentures (in which case the Trust will also defer distributions otherwise due on the trust preferred securities) for up to 20 consecutive quarters.

The debentures are subordinated to the prior payment of any other indebtedness of Trustmark that, by its terms, is not similarly subordinated. The trust preferred securities are recorded as a long-term liability on Trustmark's consolidated balance sheets; however, for regulatory purposes the trust preferred securities are treated as Tier 1 capital under the rules of the FRB, Trustmark's primary federal regulatory agency.

Trustmark also entered into a Guarantee Agreement, dated August 18, 2006, pursuant to which it has agreed to guarantee the payment by the Trust of distributions on the trust preferred securities and the payment of principal of the trust preferred securities when due, either at maturity or on redemption, but only if and to the extent that the Trust fails to pay distributions on or principal of the trust preferred securities after having received interest payments or principal payments on the junior subordinated debentures from Trustmark for the purpose of paying those distributions or the principal amount of the trust preferred securities.

As defined in applicable accounting standards, the Trust, a wholly-owned subsidiary of Trustmark, is considered a variable interest entity for which Trustmark is not the primary beneficiary. Accordingly, the accounts of the Trust are not included in Trustmark's consolidated financial statements.

At both December 31, 2025 and 2024, assets for the Trust totaled $61.9 million, resulting from the investment in junior subordinated debentures issued by Trustmark. Liabilities and shareholders' equity for the Trust also totaled $61.9 million at both December 31, 2025 and 2024, resulting from the issuance of trust preferred securities in the amount of $60.0 million as well as $1.9 million in common securities issued to Trustmark. During 2025, net income for the Trust equaled $117 thousand resulting from interest income from the junior subordinated debt securities issued by Trustmark to the Trust, compared with net income of $134 thousand during 2024 and $132 thousand during 2023. Dividends issued to Trustmark by the Trust during 2025 totaled $117 thousand, compared to $134 thousand during 2024 and $132 thousand during 2023.

With limited exception, Trustmark is no longer subject to U.S. federal, state and local audits by tax authorities for 2019 and earlier tax years. Trustmark does not anticipate a significant change to the total amount of unrecognized tax benefits within the next twelve months.

**Note 14 – 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.

*Plan Assets*

The weighted-average asset allocations by asset category are presented below for the Continuing Plan at December 31, 2025 and 2024.

---

| | | |
|:---|:---|:---|
|  | December 31, | December 31, |
|  | 2025 | 2024 |
| Money market fund | 5.0% | 2.0% |
| Exchange traded funds: |  |  |
| &nbsp;&nbsp;Equity securities | 30.0% | 33.0% |
| &nbsp;&nbsp;Fixed income | 55.0% | 59.0% |
| &nbsp;&nbsp;International | 10.0% | 6.0% |
| &nbsp;&nbsp;&nbsp;&nbsp;Total | 100.0% | 100.0% |

---

The strategic objective of the investments of the assets in the Continuing Plan aims to provide both income and potential capital appreciation. The allocation is managed on a total return basis with the average participant age in mind. It is well suited for moderately conservative investors seeking an ample level of income while also participating in equity markets. This investment mix is designed to take advantage of rising stock markets while cushioning the effects of stock market downturns. The portfolio is typically balanced between equity and fixed income. The equity exposure has the potential to earn a return greater than inflation while the fixed income exposure may reduce the risk and volatility of the portfolio to which the equity mutual funds contribute.

*Fair Value Measurements*

At this time, Trustmark presents no fair values that are derived through internal modeling. Should positions requiring fair valuation arise that are not relevant to existing methodologies, Trustmark will make every reasonable effort to obtain market participant assumptions, or independent evaluation.

The following tables set forth by level, within the fair value hierarchy, the Continuing Plan's assets measured at fair value at December 31, 2025 and 2024 ($ in thousands):

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | December 31, 2025 | December 31, 2025 | December 31, 2025 | December 31, 2025 |

| &nbsp;&nbsp;International | 156 | 156 |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Total assets at fair value | $2685 | $2685 | $— | $— |

---

There have been no changes in the methodologies used in estimating the fair value of plan assets at December 31, 2025. The money market fund approximates fair value due to its immediate maturity.

The preceding methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although Trustmark believes their valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

*Contributions*

The range of potential contributions to the Continuing Plan is determined annually by the Continuing Plan's actuary in accordance with applicable IRS rules and regulations. Trustmark's policy is to fund amounts that are sufficient to satisfy the annual minimum funding requirements and do not exceed the maximum that is deductible for federal income tax purposes. The actual amount of the contribution is determined annually based on the Continuing Plan's funded status and return on plan assets as of the measurement date, which is

------

December 31. For the plan year ending December 31, 2025, Trustmark's minimum required contribution to the Continuing Plan was $98 thousand and Trustmark contributed $109 thousand. For the plan year ending December 31, 2026, Trustmark's minimum required contribution to the Continuing Plan is expected to be $91 thousand. Management and the Board of Directors of Trustmark will monitor the Continuing Plan throughout 2026 to determine any additional funding requirements by the plan's measurement date.

*Estimated Future Benefit Payments and Other Disclosures*

The following table presents the expected benefit payments, which reflect expected future service, for the Continuing Plan ($ in thousands):

---

| | |

| 2028 | 513 |
| 2029 | 374 |
| 2030 | 334 |
| 2031 - 2035 | 1178 |

---

Amounts in accumulated other comprehensive income (loss) expected to be recognized as components of net periodic benefit cost during 2026 include a gain of $14 thousand.

***Supplemental Retirement Plans***

Trustmark maintains a nonqualified supplemental retirement plan covering key executive officers and senior officers as well as directors who have elected to defer fees. The plan provides for retirement and/or death benefits based on a participant's covered salary or deferred fees. Although plan benefits may be paid from Trustmark's general assets, Trustmark has purchased life insurance contracts on the participants covered under the plan, which may be used to fund future benefit payments under the plan. The annual measurement date for the plan is December 31. As a result of mergers prior to 2014, Trustmark became the administrator of nonqualified supplemental retirement plans, for which the plan benefits were frozen prior to the merger date.

***Other Benefit Plans***

*Defined Contribution Plan*

Trustmark provides associates with a self-directed 401(k) retirement plan that allows associates to contribute a percentage of eligible compensation, within limits provided by the Internal Revenue Code and accompanying regulations, into the plan. Trustmark matches 100% of associate contributions to the plan based on the amount of each participant's contributions up to a maximum of 6% of eligible compensation, subject to the IRS maximum eligible compensation. Associates are automatically enrolled in the plan at 3% of eligible compensation unless they opt out within 60 days of employment. Associates may become eligible to make elective deferral contributions the first of the month following one month of employment. Eligible associates that elect to participate vest immediately in Trustmark's matching contributions, as this is a Safe Harbor 401(k) Plan. Trustmark's contributions to this plan were $10.4 million in 2025, $10.7 million in 2024 and $10.8 million in 2023.

**Note 15 – Stock and Incentive Compensation Plans**

Trustmark has granted restricted stock units subject to the provisions of the Stock and Incentive Compensation Plan (the Stock Plan). Current outstanding and future grants of restricted stock units are subject to the provisions of the Stock Plan, which is designed to provide flexibility to Trustmark regarding its ability to motivate, attract and retain the services of key associates and directors. The Stock Plan also allows Trustmark to grant nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock, restricted stock units and performance units to key associates and directors. At December 31, 2025, the maximum number of shares of Trustmark's common stock available for issuance under the Stock Plan was 636,021 shares.

***Restricted Stock Grants***

*Performance Units*

Trustmark's performance units vest over three years and are granted to Trustmark's executive and senior management teams. Performance units granted vest based on performance goals of return on average tangible equity and total shareholder return. Performance units are valued utilizing a Monte Carlo simulation model to estimate fair value of the units at the grant date. The Monte Carlo simulation is performed by an independent valuation consultant and requires the use of subjective modeling assumptions. These units are amortized using the straight-line method over the requisite service period. These units are granted at 100% of target, yet provide for achievement units if performance measures exceed 100%. The restricted stock agreement for these units provides for dividend privileges, but no voting rights.

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.

**Note 16 – Commitments and Contingencies**

***Lending Related***

Trustmark makes commitments to extend credit and issues standby and commercial letters of credit (letters of credit) in the normal course of business in order to fulfill the financing needs of its customers. The carrying amount of commitments to extend credit and letters of credit approximates the fair value of such financial instruments.

Commitments to extend credit are agreements to lend money to customers pursuant to certain specified conditions. Commitments generally have fixed expiration dates or other termination clauses. Because many of these commitments are expected to expire without being fully drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The exposure to credit loss in the event of nonperformance by the other party to the commitments to extend credit is represented by the contract amount of those instruments. Trustmark applies the same credit policies and standards as it does in the lending process when making these

------

commitments. The collateral obtained is based upon the nature of the transaction and the assessed creditworthiness of the borrower. At December 31, 2025 and 2024, Trustmark had unused commitments to extend credit of $4.678 billion and $4.575 billion, respectively.

Letters of credit are conditional commitments issued by Trustmark to insure the performance of a customer to a third-party. A financial standby letter of credit irrevocably obligates Trustmark to pay a third-party beneficiary when a customer fails to repay an outstanding loan or debt instrument. A performance standby letter of credit irrevocably obligates Trustmark to pay a third-party beneficiary when a customer fails to perform some contractual, nonfinancial obligation. When issuing letters of credit, Trustmark uses the same policies regarding credit risk and collateral, which are followed in the lending process. At December 31, 2025 and 2024, Trustmark's maximum exposure to credit loss in the event of nonperformance by the other party for letters of credit was $148.7 million and $110.4 million, respectively. These amounts consist primarily of commitments with maturities of less than three years, which have an immaterial carrying value. Trustmark holds collateral to support standby letters of credit when deemed necessary.

***ACL on Off-Balance Sheet Credit Exposures***

Trustmark maintains a separate ACL on off-balance sheet credit exposures, including unfunded loan commitments and letters of credit, which is included on the accompanying consolidated balance sheets.

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

---

| | | | |
|:---|:---|:---|:---|
|  | Years Ended December 31, | Years Ended December 31, | Years Ended December 31, |
|  | 2025 | 2024 | 2023 |
| Balance at beginning of period | $29392 | $34057 | $36838 |
| &nbsp;&nbsp;&nbsp;&nbsp;PCL, off-balance sheet credit exposures | (1441) | (4665) | (2781) |
| Balance at end of period | $27951 | $29392 | $34057 |

---

Adjustments to the ACL on off-balance sheet credit exposures are recorded to PCL, off-balance sheet credit exposures. The decrease in the ACL on off-balance sheet credit exposures for the year ended December 31, 2025 was primarily due to the resolution of the Credit Quality Review qualitative factor coupled with positive credit migration. The decrease in the ACL on off-balance sheet credit exposures for the year ended December 31, 2024 was primarily reflected a decrease in required reserves as a result of changes in the total reserve rate coupled with a decrease in unfunded commitments which was partially offset by an increase in required reserves as a result of implementing the Performance Trend and the External Factor – Credit Quality Review qualitative reserve factors.

***Legal Proceedings***

Trustmark and its subsidiaries are parties to lawsuits and other claims that arise in the ordinary course of business. Some of the lawsuits assert claims related to the lending, collection, servicing, investment, trust and other business activities, and some of the lawsuits allege substantial claims for damages.

In accordance with FASB ASC Subtopic 450-20, "Loss Contingencies," Trustmark will establish an accrued liability for any litigation matter if and when such matter presents loss contingencies that are both probable and reasonably estimable. At the present time, Trustmark believes, based on its evaluation and the advice of legal counsel, that a loss in any currently pending legal proceeding is not probable and a reasonable estimate cannot reasonably be made.

**Note 17 – Shareholders' Equity**

***Regulatory Capital***

Trustmark and TB are subject to minimum risk-based capital and leverage capital requirements, as described in the section captioned "Capital Adequacy" included in Part I. Item 1. – Business of this report, which are administered by the federal bank regulatory agencies. These capital requirements, as defined by federal regulations, involve quantitative and qualitative measures of assets, liabilities and certain off-balance sheet instruments. Trustmark's and TB'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 TB and limit Trustmark's and TB's ability to pay dividends. At December 31, 2025, Trustmark and TB exceeded all applicable minimum capital standards. In addition, Trustmark and TB met applicable regulatory guidelines to be considered well-capitalized at December 31, 2025. To be categorized in this manner, Trustmark and TB 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 December 31, 2025, which Management believes have affected Trustmark's or TB's present classification.

The following table provides Trustmark's and TB's actual regulatory capital amounts and ratios under regulatory capital standards in effect at December 31, 2025 and 2024 ($ in thousands):

***Dividends on Common Stock***

Dividends paid by Trustmark are substantially funded from dividends received from TB. Prior to declaring or paying a dividend on its common stock, TB must obtain the approval of the MDBCF. In addition, approval by TB's regulators is required if the total of all dividends declared in any calendar year exceeds the total of its net income for that year combined with its retained net income of the preceding two years. In 2026, TB will have available approximately $227.4 million plus its net income for that year to pay as dividends.

***Stock Repurchase Program***

On December 6, 2022, Trustmark's Board of Directors authorized a stock repurchase program effective January 1, 2023, under which $50.0 million of Trustmark's outstanding shares could be acquired through December 31, 2023. No shares were repurchased under this stock repurchase program.

On December 5, 2023, Trustmark's Board of Directors authorized a stock repurchase program effective January 1, 2024, under which $50.0 million of Trustmark's outstanding shares could be acquired through December 31, 2024. Under this authority, Trustmark repurchased 203 thousand shares of its common stock valued at $7.5 million during the twelve months ended December 31, 2024.

On December 3, 2024, Trustmark's Board of Directors authorized a stock repurchase program effective January 1, 2025, under which $100.0 million of Trustmark's outstanding shares could be acquired through December 31, 2025.

**Note 18 – 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 the fair value of the MSR through the use of prevailing market participant assumptions and market participant valuation processes. This valuation is periodically tested and validated against other third-party firm valuations.

Trustmark obtains the fair value of interest rate swaps from a third-party pricing service that uses an industry standard discounted cash flow methodology. In addition, credit valuation adjustments are incorporated in the fair values to account for potential nonperformance risk. In adjusting the fair value of its interest rate swap contracts for the effect of nonperformance risk, Trustmark has considered any

------

applicable credit enhancements such as collateral postings, thresholds, mutual puts, and guarantees. In conjunction with the FASB's fair value measurement guidance, Trustmark made an accounting policy election to measure the credit risk of these derivative financial instruments, which are subject to master netting agreements, on a net basis by counterparty portfolio.

Trustmark has determined that the majority of the inputs used to value its interest rate swaps offered to qualified commercial borrowers fall within Level 2 of the fair value hierarchy, while the credit valuation adjustments associated with these derivatives utilize Level 3 inputs, such as estimates of current credit spreads. Trustmark has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its interest rate swaps and has determined that the credit valuation adjustment is not significant to the overall valuation of these derivatives. As a result, Trustmark classifies its interest rate swap valuations in Level 2 of the fair value hierarchy.

Trustmark also utilizes exchange-traded derivative instruments such as Treasury note futures contracts and option contracts to achieve a fair value return that offsets the changes in fair value of the MSR attributable to interest rates. Fair values of these derivative instruments are determined from quoted prices in active markets for identical assets therefore allowing them to be classified within Level 1 of the fair value hierarchy. In addition, Trustmark utilizes derivative instruments such as interest rate lock commitments in its mortgage banking area which lack observable inputs for valuation purposes resulting in their inclusion in Level 3 of the fair value hierarchy.

At this time, Trustmark presents no fair values that are derived through internal modeling. Should positions requiring fair valuation arise that are not relevant to existing methodologies, Trustmark will make every reasonable effort to obtain market participant assumptions, or independent evaluation.

***Financial Assets and Liabilities***

The following tables summarize financial assets and financial liabilities measured at fair value on a recurring basis at December 31, 2025 and 2024, segregated by the level of valuation inputs within the fair value hierarchy utilized to measure fair value ($ in thousands).

*(1) Total net (loss) gain included in Mortgage banking, net relating to the MSR includes changes in fair value due to market changes and due to run-off.* 

Trustmark may be required, from time to time, to measure certain assets at fair value on a nonrecurring basis in accordance with GAAP. Assets at December 31, 2025, which have been measured at fair value on a nonrecurring basis, include collateral-dependent LHFI. A loan is collateral dependent when the borrower is experiencing financial difficulty and repayment of the loan is expected to be provided substantially through the sale of the collateral. The expected credit loss for collateral-dependent loans is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral, adjusted for the estimated cost to sell. Fair value estimates for collateral-dependent loans are derived from appraised values based on the current market value or as is value of the collateral, normally from recently received and reviewed appraisals. Current appraisals are ordered on an annual basis based on the inspection date or more often if market conditions necessitate. Appraisals are obtained from state-certified appraisers and are based on certain assumptions, which may include construction or development status and the highest and best use of the property. These appraisals are reviewed by Trustmark's Appraisal Review Department to ensure they are acceptable, and values are adjusted down for costs associated with asset disposal. At December 31, 2025, Trustmark had outstanding balances of $24.9 million with a related ACL of $1.2 million in collateral-dependent LHFI, compared to outstanding balances of $37.1 million with a related ACL of $13.7 million in collateral-dependent LHFI at December 31, 2024. 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 $3.4 million were re-measured during 2025, requiring write-downs of $596 thousand to reach their current fair values compared to $5.5 million of foreclosed assets that were re-measured during 2024, requiring write-downs of $2.2 million.

**Note 19 – Derivative Financial Instruments**

***Derivatives Designated as Hedging Instruments***

Trustmark engages in a cash flow hedging program to add stability to interest income and to manage its exposure to interest rate movements. Interest rate swaps designated as cash flow hedges involve the receipt of fixed-rate amounts from a counterparty in exchange for Trustmark making variable-rate payments over the life of the agreements without exchange of the underlying notional

------

amount. Interest rate floor spreads designated as cash flow hedges involve the receipt of variable-rate amounts if interest rates fall below the purchased floor strike rate on the contract and payments of variable-rate amounts if interest rates fall below the sold floor strike rate on the contract. Trustmark uses such derivatives to hedge the variable cash flows associated with existing and anticipated variable-rate loan assets. At December 31, 2025, the aggregate notional value of Trustmark's interest rate swaps and floor spreads designated as cash flow hedges totaled $1.630 billion compared to $1.500 billion at December 31, 2024.

Trustmark records any gains or losses on these cash flow hedges in accumulated other comprehensive income (loss). Gains and losses on derivatives representing hedge components excluded from the assessment of effectiveness are recognized over the life of the hedge on a systematic and rational basis, as documented at hedge inception in accordance with Trustmark's accounting policy election. The earnings recognition of excluded components included in interest and fees on LHFS and LHFI totaled $526 thousand, $474 thousand and $57 thousand of amortization expense for the years ended December 31, 2025, 2024 and 2023, respectively. As interest payments are received on Trustmark's variable-rate assets, amounts reported in accumulated other comprehensive income (loss) are reclassified into interest and fees on LHFS and LHFI in the accompanying consolidated statements of income during the same period. During the next twelve months, Trustmark estimates that $704 thousand will be reclassified as a reduction to interest and fees on LHFS and LHFI. This amount could differ due to changes in interest rates, hedge de-designations or the addition of other hedges.

***Derivatives not Designated as Hedging Instruments***

Trustmark utilizes a portfolio of exchange-traded derivative instruments, such as Treasury note futures contracts and option contracts, to achieve a fair value return that economically hedges changes in the fair value of the MSR attributable to interest rates. These transactions are considered freestanding derivatives that do not otherwise qualify for hedge accounting. The total notional amount of these derivative instruments was $345.5 million at December 31, 2025 compared to $311.5 million at December 31, 2024. Changes in the fair value of these exchange-traded derivative instruments are recorded as noninterest income (loss) 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 $2.6 million, $9.2 million and $6.3 million for the years ended December 31, 2025, 2024 and 2023, 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 (loss) 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 $152.0 million at December 31, 2025, with a negative valuation adjustment of $287 thousand, compared to $110.0 million at December 31, 2024, with a positive valuation adjustment of $679 thousand.

Trustmark also utilizes derivative instruments such as interest rate lock commitments in its mortgage banking area. Interest rate lock commitments are residential mortgage loan commitments with customers, which guarantee a specified interest rate for a specified time period. Changes in the fair value of these derivative instruments are recorded as noninterest income (loss) 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 $74.5 million at December 31, 2025, with a positive valuation adjustment of $998 thousand, compared to $52.1 million at December 31, 2024, with a positive valuation adjustment of $229 thousand.

Trustmark offers certain derivatives products directly to qualified commercial lending clients seeking to manage their interest rate risk. Trustmark economically hedges interest rate swap transactions executed with commercial lending clients by entering into offsetting interest rate swap transactions with institutional derivatives market participants. Derivatives transactions executed as part of this program are not designated as qualifying hedging relationships and are, therefore, carried at fair value with the change in fair value recorded as noninterest income (loss) in bank card and other fees. Because these derivatives have mirror-image contractual terms, in addition to collateral provisions which mitigate the impact of non-performance risk, the changes in fair value are expected to substantially offset. The offsetting interest rate swap transactions are either cleared through the Chicago Mercantile Exchange for clearable transactions or booked directly with institutional derivatives market participants for non-clearable transactions. The Chicago Mercantile Exchange rules legally characterize variation margin collateral payments made or received for centrally cleared interest rate swaps as settlements rather than collateral. As a result, centrally cleared interest rate swaps included in other assets and other liabilities are presented on a net basis in the accompanying consolidated balance sheets. At December 31, 2025, Trustmark had interest rate swaps with an aggregate notional amount of $1.991 billion related to this program, compared to $1.819 billion at December 31, 2024.

***Credit-risk-related Contingent Features***

Trustmark has agreements with its financial institution counterparties that contain provisions where if Trustmark defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then Trustmark could also be declared in default on its derivatives obligations.

------

At December 31, 2025, the termination value of interest rate swaps in a liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $117 thousand compared to $568 thousand at December 31, 2024. At December 31, 2025 and 2024, Trustmark had posted collateral of $2.2 million and $1.5 million, respectively, against its obligations because of negotiated thresholds and minimum transfer amounts under these agreements. If Trustmark had breached any of these triggering provisions at December 31, 2025, it could have been required to settle its obligations under the agreements at the termination value.

Credit risk participation agreements arise when Trustmark contracts with other financial institutions, as a guarantor or beneficiary, to share credit risk associated with certain interest rate swaps. These agreements provide for reimbursement of losses resulting from a third-party default on the underlying swap. At December 31, 2025, Trustmark had entered into ten risk participation agreements as a beneficiary with an aggregate notional amount of $113.7 million compared to eleven risk participation agreements as a beneficiary with an aggregate notional amount of $83.9 million at December 31, 2024. At December 31, 2025, Trustmark had entered into twenty-seven risk participation agreements as a guarantor with aggregate notional amounts of $267.9 million compared to twenty-eight risk participation agreements as a guarantor with aggregate notional amounts of $229.1 million at December 31, 2024. The aggregate fair values of these risk participation agreements were immaterial at December 31, 2025 and 2024.

**Note 20 – Segment Information**

Trustmark's management reporting structure includes two segments: General Banking and Wealth Management. The General Banking Segment is responsible for all traditional banking products and services, including loans and deposits. The General Banking Segment also consists of internal operations such as Human Resources, Executive Administration, Treasury (Funds Management), Public Affairs and Corporate Finance. The Wealth Management Segment provides customized solutions for customers by integrating financial services with traditional banking products and services such as money management, full-service brokerage, financial planning, personal and institutional trust and retirement services. Trustmark's reportable segments are determined by the Chief Executive Officer (CEO), who is the designated chief operating decision maker (CODM), based upon information provided about Trustmark's products and services offered. The reportable segments are also distinguished by the level of information provided to the CEO, who uses such information to review performance of various lines of business, which are then aggregated if operating performance, products and services and customers are similar. The CEO evaluates the financial performance of Trustmark's lines of business, such as evaluating revenue

------

streams, significant expenses and budget to actual results, in assessing the performance of Trustmark's reportable segments and in the determination of allocating resources.

The Insurance Segment is included in discontinued operations in the accompanying consolidated statements of income for the years ended December 31, 2024 and 2023. See Note 2 – Discontinued Operations for additional information about discontinued operations.

The accounting policies of each reportable segment are the same as those of Trustmark except for its internal allocations. Noninterest expenses for back-office operations support are allocated to segments based on estimated uses of those services. Trustmark measures the net interest income of its business segments with a process that assigns cost of funds or earnings credit on a matched-term basis. This process, called "funds transfer pricing", charges an appropriate cost of funds to assets held by a business unit, or credits the business unit for potential earnings for carrying liabilities. The net of these charges and credits flows through to the General Banking Segment, which contains the management team responsible for determining TB's funding and interest rate risk strategies.

**ITEM 9A. CONTROLS AND PROCEDURES**

***Evaluation of Disclosure Controls and Procedures***

As of the end of the period covered by this Annual Report on Form 10-K, an evaluation was carried out by Trustmark's management, with the participation of its Chief Executive Officer and Treasurer and Principal Financial Officer (Principal Financial Officer), of the effectiveness of Trustmark's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934). Based upon that evaluation, the Chief Executive Officer and Principal Financial Officer concluded that the disclosure controls and procedures were effective as of the end of the period covered by this report.

***Management Report on Internal Control over Financial Reporting***

The management of Trustmark is responsible for establishing and maintaining adequate internal control over financial reporting. Trustmark's internal control over financial reporting was designed under the supervision of the Chief Executive Officer and Treasurer (Principal Financial Officer) to provide reasonable assurance regarding the reliability of financial reporting and the preparation of published financial statements in accordance with GAAP.

Management assessed the effectiveness of internal control over financial reporting as of December 31, 2025. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in *Internal Control – Integrated Framework (2013)*. Based on our assessment, we believe that, as of December 31, 2025, Trustmark's internal control over financial reporting was effective based on those criteria.

The effectiveness of Trustmark's internal control over financial reporting as of December 31, 2025 was audited by Crowe LLP, Fort Lauderdale, Florida, (U.S. PCAOB Auditor Firm I.D.: 173), an independent registered public accounting firm, as stated in their report appearing in the section captioned "Report of Independent Registered Public Accounting Firm" included in Part II. Item 8. – Financial Statements and Supplementary Data of this report.

***Changes in Internal Control over Financial Reporting***

No changes were made to Trustmark's internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) during the last fiscal quarter that materially affected, or are reasonably likely to materially affect, Trustmark's internal control over financial reporting.

**ITEM 9B. OTHER INFORMATION**

***Securities Trading Plans of Directors and Executive Officers*** 

During the three months ended December 31, 2025, none of Trustmark's directors or executive officers adopted or terminated any contract, instruction or written plan for the purchase or sale of Trustmark's securities that was intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) or any "non-Rule 10b5-1 trading arrangement" (as defined in Item 408(c) of Regulation S-K).

## Ex-10.Ac

**Exhibit 10.ac**

**TRUSTMARK CORPORATION**

**PERFORMANCE UNIT AGREEMENT**

**(Associate)**

***Granted <>***

This Performance Unit Agreement ("**Agreement**") between you and Trustmark Corporation, a Mississippi corporation ("**Trustmark**"), evidences a grant of Performance Units (the "**Award**") under the Trustmark Corporation Stock and Incentive Compensation Plan (the "**Plan**"), as of **<u><></u>** (the "**Award Date**"). This Agreement is subject to the terms and conditions of the Plan. In the event of any inconsistency or conflict between this Award Agreement and the Plan, the Plan shall govern.

**WHEREAS**, Trustmark maintains the Plan under which the Committee or Board may, among other things, award Performance Units to such key associates of Trustmark and its Subsidiaries as the Committee or Board may determine, subject to terms, conditions and restrictions as it may deem appropriate; and

**WHEREAS**, pursuant to the Plan, Trustmark, upon recommendation by the Committee and approval by Trustmark's Board, grants the Award to you subject to the terms of this Agreement and acceptance by you of this Agreement.

**NOW THEREFORE**, in consideration of the services and benefits that you will provide to Trustmark and its Subsidiaries and of the covenants contained in this Agreement, the parties hereby agree as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.**Definitions**. Capitalized terms used herein shall have the meanings ascribed to them in the Plan, except as otherwise defined in this Agreement (including <u>EXHIBIT B</u>).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.**Grant of the Award**. Trustmark hereby grants you an Award of the number of Restricted Stock Units, which shall be designated as "**Performance Units**", and the potential to earn "**Achievement Units**", as set forth on your summary page for performance stock units on the internet hosting website designated by Trustmark for the Plan. This Agreement shall not become legally binding unless you have accepted this Agreement by the Agreement due date noted with respect to the Award on the internet hosting website designated by Trustmark for the Plan (or such later date as the Chairman of the Committee may accept). *If you fail to timely accept this Agreement, the Award shall be cancelled and forfeited.* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.**Vesting**. Your Award shall vest as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>General Vesting</u>. Except as otherwise provided in Sections 3(b), 3(c) and 4 below, if you remain continuously employed throughout the period from **<u><></u>** through **<u><></u>** (the "**Performance Period**"), your Award shall vest as of the last day of the Performance Period to the extent that the Performance Goals as set forth on <u>EXHIBIT A</u> are achieved, and any balance of the Award which does not vest shall be forfeited.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Qualifying Termination</u>. If a Qualifying Termination (as defined below) occurs after <<**date**>>, but prior to the last day of the Performance Period, you will retain a Pro-Rata Portion (as defined below) of your Performance Units and have the potential to earn a Pro-Rata Portion of your Achievement Units, in each case based on the number of months you were employed during the Performance Period before the Qualifying Termination.

The **"Pro-Rata Portion"** is the amount calculated by multiplying the number of Performance Units by a fraction, the numerator of which is the number of complete calendar months from the beginning of the Performance Period to and including the date of the Qualifying Termination (such numerator not to exceed <<**#**>>), and the denominator of which is <<**#**>>. Any portion of

------

**Exhibit 10.ac**

the Award in excess of the Pro-Rata Portion shall be forfeited as of the date of the Qualifying Termination.

The Pro-Rata Portion shall not vest as of the date of the Qualifying Termination, but shall instead vest at of the end of the Performance Period only to the extent that the Performance Goals are achieved at the end of the Performance Period as set forth in <u>EXHIBIT A</u>. Any balance of the Pro-Rata Portion that does not vest at the end of the Performance Period shall be forfeited as of the end of the Performance Period.

"**Qualifying Termination**" means one of the following events, where there is no Cause for Trustmark to terminate your employment:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.<u>Retirement</u>. Your retirement from employment with the consent of the Committee or its delegate, at or after age sixty-five (65).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.<u>Termination without Cause</u>. An involuntary termination of your employment with Trustmark and its Subsidiaries; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii.<u>Termination for Good Reason not associated with a Change in Control</u>. A termination of your employment with Trustmark and its Subsidiaries at your own initiative for Good Reason (as defined in this Section 3(b)(iii)). As used in this Section 3(b)(iii), "Good Reason" means "Good Reason" as defined in your Employment Agreement (but only if you have an Employment Agreement and your Employment Agreement defines "Good Reason"). As used herein, "**Employment Agreement**" means a written individual employment agreement or change in control agreement as in effect on the Award Date between you and Trustmark or one of its Subsidiaries. If you do not have an Employment Agreement or your Employment Agreement does not define "Good Reason", this Section 3(b)(iii) shall not apply;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iv.<u>Termination for Good Reason associated with a Change in Control</u>. A termination of your employment with Trustmark and its Subsidiaries at your own initiative for Good Reason (as defined in this Section 3(b)(iv)) that occurs within the period beginning on the date on which a Change in Control (as defined in the Plan) occurs and ending on the two (2) year anniversary thereof. As used in this Section 3(b)(iv), "Good Reason" means (A) "Good Reason" as defined in your Employment Agreement (but only if you have an Employment Agreement and your Employment Agreement defines "Good Reason"), or (B) if you do not have an Employment Agreement or your Employment Agreement does not define "Good Reason", any of the following: (1) a material diminution in your authority, duties or responsibilities; (2) a material diminution in your base compensation; or (3) any requirement by Trustmark to change your principal location of employment by more than fifty (50) miles. You are required to provide notice to Trustmark of the existence of a condition that may constitute "Good Reason" within a ninety (90) day period of the initial existence of the condition, upon the notice of which Trustmark shall have thirty (30) days to remedy the condition. If the condition is remedied within thirty (30) days, then "Good Reason" does not exist. If the condition is not remedied within thirty (30) days, then you must resign within ninety (90) days of the expiration of the remedy period.

If a Vesting Acceleration Event (as defined below) occurs after a Qualifying Termination and before the end of the Performance Period, the Pro-Rata Portion will immediately vest. The Performance Period is shortened as of the end of the calendar quarter ending on or before the Vesting Acceleration Event to the extent that the Performance Goals are achieved as set forth in

------

**Exhibit 10.ac**

EXHIBIT A. Any balance of the Pro-Rata Portion that does not vest upon the Vesting Acceleration Event shall be forfeited as of the date of such event.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Vesting Acceleration Event</u>. If a Vesting Acceleration Event occurs after <<**date**>>, but prior to the last day of the Performance Period, and if you have not previously forfeited your Award under Section 4 below, a Pro-Rata Portion of your Award will be eligible for vesting based on the number of months you were employed during the Performance Period before the Vesting Acceleration Event.

The Pro-Rata Portion is calculated by multiplying the number of Performance Units by a fraction, the numerator of which is the number of complete calendar months from the beginning of the Performance Period to and including the date of the Vesting Acceleration Event (such numerator not to exceed <<**#**>>), and the denominator of which is <<**#**>>.

The Pro-Rata Portion of your award will vest as of the Vesting Acceleration Event. The Performance Period is shortened as of the end of the calendar quarter ending on or before the Vesting Acceleration Event to the extent that the Performance Goals are achieved as set forth in EXHIBIT A. Any balance of the Pro-Rata Portion that does not vest upon the Vesting Acceleration Event shall be forfeited as of the date of such event. Any balance of your Award that does not vest at the end of the Performance Period shall be forfeited as of the end of the Performance Period.

"**Vesting Acceleration Event**" means one of the following events, where there is no Cause for Trustmark to terminate your employment:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.<u>Death</u>. A termination of your employment with Trustmark and its Subsidiaries due to your death; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.**<u>"Disability"</u>**. A termination of your employment with Trustmark and its Subsidiaries due to your disability as defined in Treas. Reg. § 1.409A-3(i)(4).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.**Forfeiture**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>Cessation of Employment</u>. If your employment terminates during the Performance Period and neither Section 3(b) nor Section 3(c) applies, the Performance Units and Achievement Units shall be immediately and automatically forfeited as of the date you cease to be an employee of Trustmark or its Subsidiaries. For this purpose, transfer of employment among Trustmark and its Subsidiaries is not a termination or cessation of employment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Termination for Cause</u>. If your employment is terminated for Cause before your Performance Units or Achievement Units are settled, and notwithstanding any other provision of this Agreement, you shall immediately forfeit all Performance Units and Achievement Units, whether or not vested, and no Shares shall be issued or Dividend Equivalent (as defined below) shall be paid.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.**Voting Rights**. Neither the Performance Units nor the Achievement Units are shares of stock. Therefore, you, and any person claiming under or through you, do not possess any voting or other shareholder rights by reason or receiving Performance Units or Achievement Units pursuant to this Agreement unless and until the Performance Units or Achievement Units are settled in Shares pursuant to Section 8 hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.**Dividend Equivalent**. If Trustmark declares and pays a dividend in respect of its Stock and, on the record date for such dividend, you hold Performance Units granted pursuant to this Agreement and have the potential to earn related Achievement Units, Trustmark shall grant you an unvested right to receive an amount (the "**Dividend Equivalent**") equal to the cash dividends you would have received if you were

------

**Exhibit 10.ac**

the holder of record, as of such record date, of the number of Shares related to the Performance Units that you hold as of such record date and any related Achievement Units that you have the potential to earn. Your Dividend Equivalent will vest if, when, and to the extent that the related Performance Units vest and Achievement Units are earned and will be paid to you during the Settlement Period (as defined below). No interest will be paid with respect to Dividend Equivalents. If any portion of the Performance Units or Achievement Units are forfeited, your Dividend Equivalent shall also be forfeited in the same proportion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.**At-Will Employment Acknowledgment**. You understand and acknowledge that this Agreement does not in any manner affect your status as an Associate "at-will." As such, this Agreement does not create an express or implied contract for employment with Trustmark or any of its Subsidiaries, for any purpose or term, nor does it in any way limit the right of Trustmark or any of its Subsidiaries to otherwise terminate your employment at any time, with or without cause or notice, or impact the terms set forth in any Associate handbook or policy manual. Trustmark and its Subsidiaries reserve the right to terminate your employment at any time for any reason, with or without notice. Termination of your employment is at the sole option of the management.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.**Settlement**. All determinations of performance shall be made and certified to in writing by the Committee. Trustmark shall issue Shares corresponding to vested Performance Units and vested Achievement Units, in each case net of any applicable withholding, within 2-1/2 months following end of the Performance Period, or, if applicable, a Vesting Acceleration Event (such time period, the "**Settlement Period**"). No fractional Shares shall be issued, and the Committee, in its discretion, shall determine whether any such fractional Shares will be used to satisfy any withholding obligation or whether cash will be issued in lieu of fractional Shares or whether such fractional Shares will be forfeited or otherwise eliminated.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.**No Transfer Rights**. Neither Performance Units nor Achievement Units may be sold, assigned, transferred, pledged, hypothecated or otherwise disposed of in any manner other than by will or by the laws of decent and distribution or court order or unless otherwise permitted by the Committee on a case-by-case basis.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.**Internal Revenue Code Section 409A**. It is intended that this Agreement, the Performance Units and the Achievement Units comply with, or are exempt from, the requirements of Section 409A of the Code ("**Section 409A**"), and this Agreement and the Plan shall be administered in a manner consistent with the foregoing intent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11.**Taxes**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>Withholding</u>. Trustmark (or any of its Subsidiaries) shall have the right to retain and withhold a sufficient number of the Shares resulting from payout of this Award, or require you to remit to Trustmark (or any of its Subsidiaries) an amount sufficient to satisfy any federal, state, local or other tax withholding obligations as may be required by law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Responsibility for Taxes</u>. You acknowledge that there will be tax consequences with respect to the Award, and you should consult a tax adviser regarding your tax obligations. Regardless of the amount withheld pursuant to Section 11(a), you are solely responsible for paying all required taxes (other than Trustmark's share of employment taxes) with respect to your Award.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12.**Compliance with Laws**. The grant of the Performance Units and the Achievement Units and the issuance of any Shares pursuant to this Agreement shall be subject to, and shall comply with, any applicable requirements of any U.S. securities and other federal laws, rules and regulations and any other law, rule or regulation or exchange requirement applicable thereto. Trustmark reserves the right to impose other requirements on your participation in the Plan, on the Performance Units and the Achievement Units and on any Shares acquired under the Plan, to the extent Trustmark determines it is necessary or advisable to comply with applicable law or facilitate the administration of the Plan, and to require you to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

------

**Exhibit 10.ac**

Notwithstanding any other provision of this Agreement, Trustmark shall not be obligated to issue any Shares pursuant to this Agreement if the issuance thereof would result in a violation of any law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13.**Clawback**. You agree that the Award is subject to recoupment or clawback by Trustmark in accordance with Trustmark's recoupment, clawback or similar policy as such may be in effect from time to time, as well as any similar provisions of applicable law, or Securities and Exchange Commission rule or regulation, or stock exchange requirement, which could in certain circumstances require repayment or forfeiture of the Award or any Shares or other cash or property received with respect to the Award (including any value received from a disposition of the Shares acquired upon payment of the Award).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14.**Business Protection**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>Non-Solicitation</u>. During the full term of your employment with Trustmark or any of its Subsidiaries, and for a period of six (6) months after your termination of employment with Trustmark and its Subsidiaries, whether your employment is terminated voluntarily or involuntarily by either you or Trustmark or any of its Subsidiaries, with or without cause or notice, you will not directly or indirectly, either for your own accord or through another party or entity (whether as director, officer, consultant, principal, employee, agent or otherwise), take any action, or attempt any action, in any manner within the "Restricted Area" (as defined below): (i) to solicit or divert, or attempt to solicit or divert, any person, concern or entity which is doing business with Trustmark or any of its Subsidiaries at the time of termination of your employment from doing business with Trustmark or any of its Subsidiaries or otherwise alter its relationship with Trustmark or any of its Subsidiaries; (ii) to induce or attempt to induce any customer or supplier of Trustmark or any of its Subsidiaries to cease being a customer or supplier of Trustmark or any of its Subsidiaries, or otherwise change its relationship with Trustmark or its Subsidiaries; (iii) to disclose, directly or indirectly, to any person, firm or corporation the names or addresses, or any other information pertaining to them, of any customers or clients of Trustmark or any of its Subsidiaries that you serviced or became acquainted during the term of your employment with Trustmark or any of its Subsidiaries; or (iv) to take any other action that is directly or indirectly competitive with Trustmark or any of its Subsidiaries with respect to any customers or clients doing business with Trustmark or any of its Subsidiaries at the time of termination of your employment with Trustmark and its Subsidiaries.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Anti-Raiding</u>. During the full term of your employment with Trustmark and any of its Subsidiaries, and for a period of six (6) months after your termination of employment with Trustmark and its Subsidiaries, whether your employment is terminated voluntarily or involuntarily by either you or Trustmark or any of its Subsidiaries, with or without cause or notice, you will not directly or indirectly, either on your own accord or through another party or entity (whether as director, officer, consultant, principal, employee, agent or otherwise) attempt in any manner within the "Restricted Area" (as defined below) to solicit, employ or otherwise interfere with any of Trustmark's or its Subsidiaries' contracts or relationships with any other Associate, officer, director, shareholder or independent contractor, existing at the time of the termination of your employment with Trustmark and its Subsidiaries.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Restricted Area</u>. You understand and agree that the provisions of this Agreement contained in this Section 14 ("Business Protection"), related to your restricted activities cover (i) all geographic locations where you perform or performed work for Trustmark or its Subsidiaries, and the areas extending 75 miles from said location(s), including all location(s) over which you had management or other functional responsibilities, regardless of whether you were physically located at said location, and (ii) all geographic locations where any person, customer, client, concern or entity which is doing business with Trustmark or its Subsidiaries at the time of the termination of your employment resides, exists, operates or does business, as well as the areas extending 75 miles from said location(s).

------

**Exhibit 10.ac**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Consideration</u>. You agree that, in exchange for your continued employment with Trustmark or its Subsidiaries, as well as your eligibility to participate in the Plan and receive this Award, you are bound by the terms and conditions set forth in these restrictive, business protection covenants. You further acknowledge that your obligations within these restrictive, business protection covenants last for the duration of your employment with Trustmark or any of its Subsidiaries, and for a period of six (6) months thereafter, regardless of the vesting and/or forfeiture of the Restricted Stock Units subject to this Award. You also agree that you are bound by the terms of these restrictive covenants after agreeing to their terms initially and acknowledge the fact that you continue to be bound by these restrictive covenants even if you receive any additional awards/grants.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)<u>Acknowledgment</u>. You have carefully considered the nature and extent of the restrictions upon you, and the rights and remedies conferred upon Trustmark and its Subsidiaries under this Agreement, and hereby acknowledge and agree that the same: (i) are reasonable in time and geographical scope and are designed to eliminate activities that would otherwise be unfair to Trustmark and its Subsidiaries, in light of the protectable interests of Trustmark, its Subsidiaries and their business operations; (ii) in the event your employment with Trustmark and its Subsidiaries terminates for any reason, will not prevent you from earning a livelihood without violating the above described restrictions; (iii) do not confer a benefit upon Trustmark or its Subsidiaries disproportionate to any detriment to you; and (iv) are fully required to protect Trustmark's and its Subsidiaries' legitimate, protectable interests as a leader in the banking and financial services industries involving confidential information including Trustmark's and its Subsidiaries' goodwill, relationships, confidential information and other legally recognized protectable interests.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)<u>Enforcement of Restrictive Covenants/Relief for Violations</u>. You acknowledge that Trustmark and its Subsidiaries have a protectable interest in enforcing the non-solicitation and anti-raiding provisions of the Agreement for the full length of your employment and for the 6 month term following the termination of your employment. You agree that any violation of any provision of the Agreement will result in immediate, irreparable harm to Trustmark and its Subsidiaries and that money damages alone would not be an adequate remedy for any such violation. In addition to the rights and remedies conveyed in this Agreement, Trustmark and its Subsidiaries shall be entitled, and is expressly and irrevocably authorized by you, to seek specific enforcement and injunctive relief in a court of competent jurisdiction, without posting a bond or other security. This section shall in no manner be construed to limit other causes of action, rights, and relief to which Trustmark or its Subsidiaries may be entitled. You recognize that if Trustmark or any of its Subsidiaries is successful in obtaining any of the requested relief or damages under the terms of this Agreement, you must pay reasonable attorneys' fees, costs and expenses incurred by Trustmark or its Subsidiaries in enforcing and obtaining relief or damages available under this Agreement. Without limiting the generality of the foregoing, the rights and remedies of Trustmark and its Subsidiaries, and your obligations under this Agreement, are in addition to any respective rights, remedies and obligations under applicable law (including, but not limited to, laws relating to misappropriation of trade secrets) and under any other agreement between you and Trustmark or any of its Subsidiaries.

<u>Performance Goals</u>

1.*Generally*. Vesting of the Award shall be determined by (i) the average of Trustmark's ROATCE for each calendar year in the Performance Period compared to the target ROATCE ("**Target**") determined by the **<u><></u>** three-year Strategic Plan approved by Trustmark's Executive Committee of the Board and recommended to, and approved by, Trustmark's Board; and (ii) Trustmark's TSR ranking for the Performance Period compared to the TSR for the Peer Group over the same period as follows, where vesting in the Award is equal to the number of the Restricted Stock Units multiplied by the sum of the vesting percentage in (A) and the vesting percentage in (B) below:

---

| | | | | |
|:---|:---|:---|:---|:---|
| &nbsp;&nbsp;ROATCE<br><u>Performance</u> | &nbsp;&nbsp;(A)<br>ROATCE<br>Vesting <u>Percentage</u> |  | &nbsp;&nbsp;TSR<br><u>Ranking</u> | &nbsp;&nbsp;(B)<br>TSR<br>Vesting <u>Percentage</u> |
| &nbsp;&nbsp;<<%>> of Target | &nbsp;&nbsp;100% | &nbsp;&nbsp;+ | &nbsp;&nbsp;<> Percentile | &nbsp;&nbsp;100% |
| &nbsp;&nbsp;<<%>> of Target | &nbsp;&nbsp;88% | &nbsp;&nbsp;+ | &nbsp;&nbsp;<> Percentile | &nbsp;&nbsp;90% |
| &nbsp;&nbsp;<<%>> of Target | &nbsp;&nbsp;75% | &nbsp;&nbsp;+ | &nbsp;&nbsp;<> Percentile | &nbsp;&nbsp;70% |

2. Inter*polation*. If Trustmark's performance or ranking, as applicable, is above the threshold (<<%>> of Target for ROATCE or above <> percentile for TSR), but less than the maximum (<<%>> of Target for ROATCE or <> percentile for TSR), then the vesting percentage shall be determined by straight line interpolation (rounded, where not otherwise resulting in a whole or half percent, to the next lowest whole or half percent) where the performance or ranking falls between identified tiers (for example, if the TSR ranking is in the <> percentile, then the vesting percentage is <<%>>).

3.*Vesting and Settlement*. If the aggregate vesting is 100% or lower, only Performance Units shall vest and be settled in accordance with Section 8 of this Agreement. If the aggregate vesting exceeds 100%, Achievement Units shall also vest and be settled in accordance with Section 8 of this Agreement.

4.*Shortened Performance Period*. The period of time from the beginning of the Performance Period to the calendar quarter ending on or before the Vesting Acceleration Event shall be referred to as the "**Shortened Performance Period**". Performance Goals under a Shortened Performance Period shall be determined by (i) the average of Trustmark's ROATCE for each calendar quarter in the Shortened Performance Period compared to the Target ROATCE; and (ii) Trustmark's TSR ranking for the Performance Period compared to the TSR for the Peer Group over the same period, where vesting in the Award is equal to the Pro-Rata Portion multiplied by the sum of the vesting percentage in (A) and the vesting percentage in (B) in the table above.

Insider Trading Policy

------

# 2 Purpose

------

The purpose of this Insider Trading Policy ("Policy") is to establish policies and procedures regarding trading in securities issued by Trustmark Corporation ("Trustmark") by members of Trustmark's board of directors ("directors") and Trustmark's officers and associates.

# 3 Goals/Objectives of the Policy

------

The objective of this Policy is to help Trustmark's directors, officers and associates comply with insider trading laws, handle confidential information properly, avoid potentially embarrassing public disclosures and avoid the appearance of impropriety.

# 4 Scope of the Policy

------

4.1 General Prohibition

Any director, officer or associate who has material non-public information ("Inside Information") relating to Trustmark may not, until the Inside Information becomes public, (i) buy or sell securities issued by Trustmark, directly or indirectly, (ii) engage in any other action to take personal advantage of that information, or (iii) pass it on to others outside Trustmark. In addition, any director, officer, or associate who learns of Inside Information about another entity, including but not limited to another entity with whom Trustmark does business, or proposes to do business, may not trade in that entity's securities until the Inside Information becomes public.

To ensure compliance with this policy, all directors, officers, and associates of Trustmark must:

 protect the confidentiality of Inside Information, by, for example, avoiding casual conversations about such Inside Information in public areas and storing files containing Inside Information in secure locations; and

 report any unauthorized disclosure of Inside Information, whether inadvertent or otherwise, immediately to the Trading Coordinator, whose contact information can be found in Section 12 of this Policy.

It is also Trustmark's policy that it will not engage in transactions in Trustmark securities while Trustmark is in possession of material non-public information relating to Trustmark or its securities, other than in compliance with applicable law, including, but not limited to, Rule 10b5-1 under the Securities and Exchange Act of 1934, as amended (the "Exchange Act"). Any such transactions on behalf of Trustmark must be authorized by the Board of Directors or effected pursuant to properly delegated Board authority.

Insider Trading Policy

4.2 "Inside Information" Defined

For the purpose of this Policy, Inside Information is (1) material and (2) non-public information. Information is "non-public" if not available to the investing public generally. Information typically will no longer be considered to be "non-public" once two trading days have elapsed since the information was disseminated widely to the investing public, such as through a press release carried over a major news service, a public filing with the Securities and Exchange Commission (the "SEC") or materials sent to stockholders (e.g., a proxy statement). The distribution of information through narrower channels, such as postings on rarely-frequented websites, may be insufficient to make it public, and the posting of information on social media does not constitute public dissemination. Also, the fact that non-public information is reflected in rumors in the marketplace does not mean that the information has been publicly disseminated. It is important to note that even after information becomes public, many aspects relating to a matter may remain non-public.

Information is considered "material" if there is a substantial likelihood that a reasonable investor would consider the information important in making an investment decision to buy, sell or hold securities, or if it is reasonably likely to affect the market price of a security. Examples of information that may be material include:

 Quarterly and annual earnings information,

 Changes in earnings estimates,

 Changes in dividend policy,

 Significant mergers, acquisitions, or divestitures,

 Acquisition or loss of a significant contract,

 Changes in key management personnel,

 Important product developments,

 Changes in business strategies,

 Significant financial developments, and

 Threatened litigation or administrative actions, or material developments in such matters.

The foregoing list does not include all of the information that could be deemed to be material. Further, the courts and the SEC have declined to identify all information that could be deemed to be material. If you are uncertain whether you are in possession of material non-public information, you are required to consult with the Trading Coordinator.

4.3 Violations of Insider Trading Laws

Violations of insider trading laws can severely damage Trustmark's reputation and can result in severe civil and criminal penalties for the individuals involved, Trustmark management and Trustmark itself. Directors, officers and associates who violate this Policy are subject to appropriate disciplinary action, which could include termination of employment.

------

Administration5

------

Insider Trading Policy

------

Violation of insider trading laws could result in civil or criminal penalties under applicable federal securities laws. The SEC and the Department of Justice vigorously pursue alleged violations of the insider trading laws, even in cases where the alleged illegal profit is very small. The sanctions for individuals who trade on inside information (or tip information to others) include:

 a civil penalty of up to three times the profit gained or loss avoided;

 a criminal fine (no matter how small the profit) of up to $5 million ($25 million for a corporation);

 a jail term of up to 20 years; and

 a temporary or permanent bar from serving as an officer or director of any public company.

Insider trading violations can also expose Trustmark (and possibly supervisory personnel) to civil or criminal liability.

Finally, private lawsuits also may be brought against illegal traders by persons who traded without access to the material non-public information and incurred losses.

As a reminder, anyone scrutinizing the transactions of a director, officer or associate will be doing so after the fact, with the benefit of hindsight. Before engaging in any transaction, each director, officer or associate should carefully consider how enforcement authorities and others might view the transaction in hindsight.

# 5 Target Audience

------

5.1 Generally

This Policy applies to all directors, officers and associates of Trustmark (collectively, "Covered Persons"). Additionally, this Policy applies to any family members who reside with a Covered Person, anyone else who lives in the household of a Covered Person, and any family members who do not live in a Covered Person's household but whose transactions in Trustmark securities are directed by a Covered Person or are subject to influence or control by a Covered Person.

5.2 Additional Provisions Applicable to Insiders

Trustmark has established additional restrictions for those persons who, because of the nature of their employment or positions, are most likely to have access to Inside Information regarding Trustmark. These individuals, referred to as "Insiders" include (a) any member of Trustmark Bank's Executive Strategy Committee, (b) those associates identified as "Insiders" on a list maintained by the Trading Coordinator, as such list may be determined from time to time by the Trading Coordinator or by the Board of Directors of Trustmark, and (c) individuals who serve on the Board of Directors of Trustmark or Trustmark Bank.

# 6 Roles and Responsibilities

------

Administration6

------

Insider Trading Policy

------

The Trading Coordinator (as identified in Section 12) or the Board of Directors of Trustmark shall be responsible for identifying Insiders for purposes of this Policy.

The Trading Coordinator shall be responsible for distributing the approved Policy to all Insiders in December of each year. All Insiders shall be responsible for submitting the Certification set forth in Schedule 13.1 to the Trading Coordinator in accordance with Section 8.3.6 hereof.

# 7 Relevant Regulatory Requirements and Guidance

------

The terms of this Policy are designed to promote compliance with applicable law, including the Exchange Act, and the SEC's rules and regulations promulgated thereunder.

# 8 Policy Standards

------

8.1 Post-Termination Transactions

If any director, officer or associate of Trustmark or its subsidiaries is in possession of Inside Information when his or her employment or service terminates, such individual may not trade in Trustmark securities until that information has become public or is no longer material. In addition, an Insider will continue to be subject to the provisions of this Policy applicable to Insiders, including the black-out period, until completion of the first quarterly black-out period (as described in Section 8.3.2) following termination of such Insider's employment or service.

8.2 Hedging Transactions

Hedging transactions may misalign a Trustmark associate's objectives with those of the company. Furthermore, the counterparty to a hedging transaction frequently seeks to short the underlying security to hedge its exposure on the transaction, which is not consistent with the interests of Trustmark or its shareholders. Therefore, Trustmark associates are prohibited from engaging in any hedging transactions with respect to any of Trustmark's securities including trading in any derivative security relating to Trustmark's securities. As noted in Section 8.3.5, shorting Trustmark securities is not consistent with the interests of Trustmark or its security holders. Therefore, Covered Persons are prohibited from engaging in any form of hedging transaction with respect to any Trustmark security.

Insider Trading Policy

------

8.3 Additional Restrictions Applicable to Insiders

Compliance with securities laws is the responsibility of the Insider; however, Trustmark has an interest in assisting its Insiders in complying with applicable laws. In order to simplify compliance, Insiders shall conduct trades in accordance with the following procedures. Any questions regarding these procedures should be directed to the Trading Coordinator.

8.3.1 Beneficial Ownership

The procedures in this Section 8.3.1 apply to all securities, which are beneficially owned by the Insider. An individual is deemed to beneficially own securities in which he or she has a direct or indirect pecuniary interest—that is, the opportunity to profit or share in any profit derived from a transaction in the security. An individual is considered to have an indirect pecuniary interest, among other situations, in (i) shares held by members of the individual's immediate family or certain other persons sharing the same household and family members whose transactions are directed or influenced by such individual, (ii) securities held by a trust of which the individual is a trustee and either the individual or a member of his or her family is a beneficiary, (iii) the individual's proportionate interest in any securities held by a general or limited partnership, (iv) securities the individual can acquire through the exercise or conversion of any warrant, option or similar interest and (v) securities held by a corporation or similar entity in which the individual is a controlling shareholder and has investment control over the entity's investment portfolio.

8.3.2 Black-Out Periods

Insiders are prohibited from trading in Trustmark securities during four black-out periods each year. Each black-out period begins on the 15<sup>th</sup> day of the last month of Trustmark's fiscal quarter and concludes at the close of business two trading days following the quarterly earnings release.

Trustmark may also impose additional black-out periods on specified Insiders in the event of a major corporate development that has not been announced to the public. The Trading Coordinator will inform affected Insiders of the commencement and termination of any additional black-out periods. An Insider made aware of the existence of an event-specific black-out period may not disclose the existence of the black-out period to any other person. Any failure of the Trading Coordinator to designate an Insider as being subject to an event-specific black-out period will not relieve that Insider of the obligation not to trade while aware of Inside Information.

The trading restrictions described above apply to all exercises of stock options, regardless of the manner in which the exercise price of the option is to be paid.

**8.3.3.1 Vesting of Restricted Stock/Restricted Stock Units**

Insider Trading Policy

------

The trading restrictions described above do not apply to tax withholding pursuant to which an Insider elects to have Trustmark withhold shares of restricted stock or restricted stock units to satisfy tax obligations associated with vesting. The trading restrictions described above do apply, however, to the sale of any shares, including a sale for the purpose of generating the cash needed to pay the tax obligations associated with vesting.

**8.3.3.2 401(k) plan**

The trading restrictions described above do not apply to automatic purchases of Trustmark securities in the Trustmark 401(k) Plan (the "401(k) Plan") resulting from an Insider's periodic contribution of money to the plan pursuant to a deduction election. The trading restrictions described above do apply, however, to discretionary transactions an Insider may make under the 401(k) Plan, including an election to make an intra-plan transfer of an existing account balance into or out of Trustmark securities.

**8.3.3.3 Employee and Director Stock Purchase Plan**

The trading restrictions described above do not apply to automatic purchases of Trustmark stock in the Employee and Director Stock Purchase Plan (the "Stock Purchase Plan") resulting from the periodic contribution of money to the Stock Purchase Plan pursuant to the election made (i) at the time of enrollment in the Stock Purchase Plan and (ii) while a black-out period is not in effect. The trading restrictions described above do apply, however, to an Insider's election to participate in the Stock Purchase Plan for any enrollment period and to the sale of Trustmark stock purchased pursuant to the Stock Purchase Plan.

**8.3.3.4 Dividend Reinvestment Plan**

The trading restrictions described above do not apply to automatic purchases of Trustmark stock under the Dividend Reinvestment and Direct Stock Purchase and Sale Plan or under certain broker-provided dividend reinvestment plans resulting from an Insider's reinvestment of dividends paid on Trustmark stock. The trading restrictions described above do apply, however, to voluntary purchases of Trustmark stock resulting from additional contributions an Insider chooses to make to such a plan, and to an Insider's election to participate in such a plan or to change his or her level of participation in such a plan. The trading restrictions described above also apply to the sale of any Trustmark stock purchased pursuant to such a plan.

**8.3.3.5 Gifts**

The trading restrictions described above do apply to certain bona fide gifts of Trustmark securities (such as charitable donations or family gifts or estate planning transfers). Insiders may <u>not</u> make a gift or donation of Trustmark securities while aware of Inside Information or during a black-out period, <u>if</u> the Insider (a) anticipates that the recipient will sell the securities before the Inside Information is made public or before the black-out period expires, as applicable, or (b) will receive value related to the gift or donation (e.g., the Insider would receive a tax deduction related to a charitable donation). With respect to other bona fide gifts of Trustmark stock, the trading restrictions described above do not apply.

8.3.4 Rule 10b5-1 Trading Plans

Rule 10b5-1 under the Exchange Act provides an affirmative defense from insider trading liability. In order to rely on this affirmative defense, an Insider must enter into a Rule 10b5-1 plan for transactions in Trustmark securities that meets the conditions specified in the following paragraph (a "Rule 10b5-1 Plan"). If the plan meets the requirements of Rule 10b5-1, Trustmark securities may be purchased or sold under the Rule 10b5-1 Plan without regard to certain insider trading restrictions.

An Insider may not enter into a Rule 10b5-1 Plan when that person is aware of Inside Information or during a black-out period. To meet the requirements of Rule 10b5-1 the Insider must enter into a binding contract and provide an instruction to another person or adopt a written plan for trading securities that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· specifies the amount of securities to be bought or sold, as well as the price and date of the transaction(s);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· includes a written formula, algorithm or computer program for determining the amount, price and date of the purchase(s) or sale(s); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· does not permit the person to exercise any subsequent influence over how, when or whether to effect purchases or sales, while at the same time ensuring that any person effecting trades under the Rule 10b5-1 Plan is not aware of any material non-public information while doing so.

An Insider who wishes to implement a Rule 10b5-1 Plan must pre-clear such plan with the Trading Coordinator at least two weeks prior to the proposed effective date of the plan. The following requirements must be met for the Rule 10b5-1 Plan to be approved:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· any Insider proposing to adopt a Rule 10b5-1 Plan must include a representation certifying that he or she is adopting the plan in good faith, at a time when he or she is not in possession of Insider Information and not as part of a plan to evade insider trading prohibitions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the Rule 10b5-1 Plan must include a cooling-off period between the adoption of the plan and the first trade under the plan that (i) for Section 16 Insiders (as defined below in Section 9) lasts until the later of (A) 90 days after the adoption of the Rule 10b5-1 Plan and (B) two business days following the disclosure of Trustmark's financial results on a Form 10-Q or Form 10-K for the completed fiscal quarter in which the Rule 10b5-1 Plan is adopted; provided, however, that in no event will the required cooling-off period exceed 120 days following the adoption of the Rule 10b5-1 Plan and (ii) for all other Insiders, lasts for at least 30 days after the adoption of the Rule 10b5-1 Plan; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the proposed Rule 10b5-1 Plan must otherwise meet all other conditions and restrictions of Rule 10b5-1, including restrictions on having more than one Rule 10b5-1 Plan in effect at the same time and having more than one Rule 10b5-1 Plan that is intended to effect the open-market purchase or sale of a total amount of securities as a single transaction in any 12-month period.

The Trading Coordinator must be promptly notified of any amendments to, or termination of, any Rule 10b5-1 Plan. Any modification of the amount, pricing or timing of purchase(s) or sale(s) of securities under

------

Administration10

------

Insider Trading Policy

------

a Rule 10b5-1 Plan will constitute the termination of the Rule 10b5-1 Plan and the adoption of a new plan, which means that any such modification will trigger the need for the new trading plan to satisfy all of the elements of Rule 10b5-1 and the conditions set forth above, including a new cooling-off period, before trading can begin under the new plan.

8.3.5 Additional Prohibited Transactions

Trustmark considers it inappropriate for any Insider to engage in short-term or speculative transactions in Trustmark securities. Accordingly, Insiders may not engage in any of the following transactions:

**8.3.5.1 Short Sales**

Short sales of Trustmark securities evidence an expectation on the part of the seller that the securities will decline in value and therefore may signal to the market that the seller has no confidence in Trustmark or its short-term prospects. In addition, short sales may reduce the seller's incentive to promote Trustmark's performance. For these reasons, Insiders are prohibited from engaging in short sales of Trustmark securities. This prohibition extends to so-called short sales against the box, where the seller may own the securities being sold, but does not deliver those securities to cover the sale order.

**8.3.5.2 Publicly Traded Derivatives**

A transaction in a derivative instrument that is tied to a Trustmark security, such as non-compensatory options, is, in effect, a bet on the short-term movement of that Trustmark security and, therefore, creates the appearance that an Insider is trading based on Inside Information. Transactions in non-compensatory options also may focus an Insider's attention on short-term performance at the expense of Trustmark's long-term objectives. Accordingly, Insiders are prohibited from engaging in transactions in puts, calls or other derivative securities, on an exchange or in any other organized market, with respect to Trustmark securities. (Option positions arising from certain types of hedging transactions are governed by "Hedging Transactions" above).

**8.3.5.3 Margin Accounts and Pledges**

Securities held in a margin account may be sold by the broker without the customer's consent if the customer fails to meet a margin call. Similarly, securities pledged or otherwise hypothecated as collateral for a loan may be sold in foreclosure if the borrower defaults on the loan. Insiders are prohibited from holding Trustmark securities in a margin account or pledging Trustmark securities as collateral for a loan. An exception to this prohibition may be granted where an Insider wishes to pledge Trustmark securities as collateral for a loan (not including margin debt) and clearly demonstrates the financial capacity to repay the loan without resort to the pledged securities. Any request for approval of such a pledge arrangement must be submitted to the Trading Coordinator at least two weeks prior to the proposed execution of documents evidencing the proposed pledge.

8.3.6 Required Certification

All Insiders must annually certify their understanding of and intent to comply with this Policy by signing and dating the Certification set forth in Schedule 13.1 of this Policy and submitting the same to the Trading Coordinator, whose contact information can be found in Section 12 of this Policy, on or before December 31 of each year.

# 9 Reporting Requirements of Section 16(A)

------

Section 16(a) of the Exchange Act requires that Trustmark's directors, officers (as defined in Rule 16a-1(f) under the Exchange Act) and 10% beneficial owners (collectively, "Section 16 Insiders") file beneficial ownership reports in connection with their purposes and sales of Trustmark's securities.

9.1 Form 3

A Section 16 Insider must file a Form 3 (entitled "Initial Statement of Beneficial Ownership of Securities") with the SEC to report that he or she is an Insider and his or her ownership interests in Trustmark within ten days after becoming a Section 16 Insider.

9.2 Forms 4 and 5

A Section 16 Insider must file a Form 4 (entitled "Statement of Changes in Beneficial Ownership") with the SEC to report a transaction within two business days after the date of such transaction if it results in a change in his or her beneficial ownership of Trustmark's equity securities. There are three general exceptions to the two-business-day reporting requirement.

First, the following types of transactions may be reported on a Form 4 within two business days following the date the Section 16 Insider receives notice of the transaction (but in no event later than five business days following the transaction), rather than two business days following the date on which the transaction occurs:

 a transaction pursuant to a Rule 10b5-1 plan under which the Section 16 Insider does not select the date on which the purchases or sales take place; and

 a "discretionary transaction" (as defined in Rule 16b-3) pursuant to an employee benefit plan for which the Section 16 Insider does not select the date on which transactions take place (such as transfers in or out of, or cash withdrawals from, a company stock fund in a 401(k) plan or other employee benefit plan).

Second, certain transactions may, and in a few instances must, be reported on a year-end Form 5. A Form 5 must be filed with the SEC within 45 days after the end of such fiscal year by each person who was a Section 16 Insider for any part of a company's fiscal year (unless he or she has no transactions to report on Form 5). There are certain types of stock transactions that the SEC has designated as eligible for Form

------

Administration12

------

Insider Trading Policy

------

5 filing (rather than a Form 4 filing). Section 16 Insiders also must report on a Form 5 all transactions that occurred during the fiscal year that should have been, but were not, reported earlier on Form 4.

Third, the following types of transactions do not trigger any Form 4 or Form 5 filing requirement:

 an acquisition under an employee stock purchase plan;

 a transaction (other than a "discretionary transaction") under certain employee benefit plans, such as pension plans, 401(k) plans, or related excess benefit plans;

 an acquisition through a stock split, stock dividend, or other pro rata distribution to stockholders of Trustmark;

 an acquisition under certain dividend or interest reinvestment plans; and

 an acquisition or disposition as a result of a domestic relations order (such as a divorce decree).

Although these transactions do not require the filing of a Form 4 or Form 5, the next Form 4 or Form 5 filed after the occurrence of one of these transactions is required to reflect the effects of these transactions in the column reporting post-transaction security ownership.

9.3 Form 144

Most sales of Trustmark securities, which may include sales from the 401(k) Plan, where the amount sold in any three-month period exceeds 5,000 shares or $50,000 in value also require the Section 16 Insider to file a Form 144 with the SEC no later than the time the Section 16 Insider places the sale order with a broker or executes the trade directly with a market maker.

9.4 Preparation of Forms 3, 4, 5 and 144

Although the responsibility for the timely filing of reports and compliance with trading restrictions rests with each Section 16 Insider, to assist Trustmark's Section 16 Insiders, the Trading Coordinator will prepare all necessary reporting forms on behalf of Section 16 Insiders who are directors or who are members of Trustmark Bank's Executive Strategy Committee. All Forms 3, 4, 5 and 144 prepared on behalf of a Section 16 Insider will be based on information provided by the Section 16 Insider. All Insiders must fill out and deliver to the Trading Coordinator a Form ID (a form to obtain access codes to file on the SEC's electronic filing system).

**To meet SEC reporting requirements, all transactions in securities beneficially owned by a Section 16 Insider (which may include transactions by persons <u>other</u> <u>than</u> the Section 16 Insider, as further described in Section 8.3.1) must be reported promptly to the Trading Coordinator.** The SEC requires that specific information concerning any late filing be reported in Trustmark's annual proxy statement.

9.5 Short-Swing Profit Recapture Rule of Section 16(b)

Section 16(b) of the Exchange Act provides that any combination of purchase and sale or sale and purchase (in each case, not exempt from Section 16(b)) of the issuer's securities (including derivative securities) within a period of less than six months generally results in a violation of Section 16(b). If Section 16(b) is violated, any profit from the matched transactions must be recovered by Trustmark from the Section 16

------

Administration13

------

Insider Trading Policy

------

Insider. Profit is determined by matching the highest priced sale with the lowest priced purchase, without regard to the actual profit made by the Section 16 Insider.

Although the purpose of the statute is to prevent trading on the basis of material non-public information, the recovery provision operates without regard to the intent of the Section 16 Insider or the actual possession of Inside Information.

Prior to a purchase or sale of Trustmark securities, transactions within the previous six months should be carefully reviewed by the Section 16 Insider. Again, consideration should be given to transactions involving any securities beneficially owned by the Section 16 Insider, which includes transactions by members of the Section 16 Insider's household, as further described in Section 8.3.1.

9.6 Post-Termination Requirements

Following termination of employment or service, Section 16 Insiders are required to continue reporting certain post-termination transactions that occur less than six months after the last opposite-way, non-exempt transaction that occurred prior to termination. This means that Section 16 reporting obligations may continue for up to six months following termination. To comply with these requirements, all transactions in Trustmark securities beneficially owned by a Section 16 Insider (which may include transactions by persons <u>other</u> <u>than</u> the Section 16 Insider, as further described in Section 8.3.1) must be reported promptly to the Trading Coordinator for six months after such Section 16 Insider terminates employment or service.

# 10 Policy Oversight and Review
