Report of Independent Registered Public Accounting Firm
 
The Associate Benefits Subcommittee and Participants
Trustmark 401(k) Plan
Jackson, Mississippi
 
Opinion on the Financial Statements
 
We have audited the accompanying statements of net assets available for benefits of the Trustmark 401(k) Plan (the “Plan”) as of December 31, 2025 and 2024, the related statements of changes in net assets available for benefits for the years then ended and the related notes (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2025 and 2024, and the changes in net assets available for benefits for the years then ended in conformity with accounting principles generally accepted in the United States of America.
 
Basis for Opinion
 
These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’s financial statements 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 Plan 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion.
 
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
 
Supplemental Information
 
The supplemental information included in Schedule H, Line 4(i) – Schedule of Assets (Held at End of Year) as of December 31, 2025, has been subjected to audit procedures performed in conjunction with the audits of the Plan’s financial statements. The supplemental information is the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information in the accompanying schedule, we evaluated whether the supplemental information, including its form and content, is presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental information in the accompanying schedule is fairly stated in all material respects, in relation to the financial statements as a whole.

TRUSTMARK 401(k) PLAN
Years Ended December 31, 2025 and 2024
 
NOTES TO FINANCIAL STATEMENTS
 
Note 1. Plan Description
 
The following description of the Trustmark 401(k) Plan (the "Plan") provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions.
 
General
 
The Plan is a defined contribution plan established for the associates of Trustmark Corporation (the "Company") and certain other associated companies. The Plan is subject to the provisions of the Employee Retirement Income Security Act ("ERISA") of 1974, as amended.
 
Eligibility
 
The Plan provides eligibility for participation in elective deferrals by associates on the first day of the month after one month of employment.
 
Plan Administration
 
Empower Retirement refers to the products and services offered in the retirement markets by Empower Annuity Insurance Company of America (“EAICA”), formerly known as Great-West Life & Annuity Insurance Company (“GWL&A”). Empower Trust Company, LLC is a subsidiary of EAICA and is the custodian of the Plan’s assets. The Plan administrator and sponsor is Trustmark Corporation, parent company of Trustmark Bank. All trustee functions related to the employer stock held by the Plan are handled by Newport Trust Company and all trustee functions related to all other Plan investments are handled by Empower Trust Company.
 
Participant Contributions
 
The Plan allows participants to make voluntary before‑tax salary deferral contributions, through payroll deductions, to separately invested funds in accordance with Section 401(k) of the Internal Revenue Code ("IRC"). If certain requirements of IRC Section 401(k) are not met in Plan operation, the salary deferral agreements of participants may, on a nondiscriminatory and uniform basis, be amended or revoked to preserve the qualified status of the Plan.
 
All newly eligible participants are automatically enrolled in the Plan unless they affirmatively elect not to participate in the Plan or elect to participate at a different rate. Automatically enrolled participants have their initial deferral rate set at 3% of their eligible compensation. The deferral rate automatically increases by 1% annually up to a maximum deferral rate of 6%.
 
Participants may elect to contribute through the Roth 401(k) contribution option on an after-tax basis. The Roth 401(k) contributions qualify for matching contributions and are otherwise subject to the same combined dollar limits applicable to pre-tax contributions.
 
Participants may elect to contribute up to 75 percent of eligible compensation each period, subject to regulatory limitations. Any excess contributions must be returned to the applicable participant by March 15 of the calendar year following the year of excess contributions. The Plan allows for rollover contributions from individual retirement accounts or other qualified plans.

TRUSTMARK 401(k) PLAN
Years Ended December 31, 2025 and 2024
 
NOTES TO FINANCIAL STATEMENTS
 
Note 1. Plan Description (Continued)
 
Provisions of the Plan allow participants who were age 50 years or older by the end of the calendar year to make catch‑up contributions to the Plan. Catch‑up contributions represent associate compensation deferrals in excess of certain Plan limits and statutory limits, including Internal Revenue Service ("IRS") annual deferral limits.
 
Employer Contributions
 
Full-time and part-time associates are eligible to receive the safe harbor matching contribution on the first day of the month following one month of service. Eligible participant contributions are matched by the employer at a rate of 100 percent of the first 6 percent of covered compensation. The employer may also make discretionary contributions. No discretionary contributions were made for the years ended December 31, 2025 and 2024.
 
Participant Accounts
 
Each participant's account is credited with the participant's contributions and allocations of (a) the Company's contributions and (b) Plan earnings (losses) and charged with an allocation of administrative expenses. Allocations are based on participant compensation deferrals or account balances, as defined.
 
Investment Options
 
Participants may direct investments of their account balance among several investment options.
 
The Plan provides participants the opportunity to annually elect whether cash dividends paid on employer stock will be invested in shares of employer stock within the individual participant's account or be paid to the participant in cash.
 
Vesting
 
Participants are immediately vested in their voluntary contributions, all employer contributions made on their behalf and the investment earnings and losses thereon.
 
Payment of Benefits
 
On retirement, death, disability or termination of service, a participant may elect to receive a lump‑sum distribution equal to the total of his or her account balance or in installments. In addition, hardship distributions are permitted if certain criteria are met.
 
Notes Receivable from Participants
 
Participants may borrow from their vested account balance a minimum of $1,000 up to a maximum of $50,000 or 50% of their account balance, whichever is less. The loans are secured by the balance in the participant’s account and bear interest at commercially reasonable rates as determined under the Plan. On December 31, 2025, the interest rate on all outstanding participant loans was from 4.25% to 9.50% with maturity dates ranging from January 2026 to May 2040.

TRUSTMARK 401(k) PLAN
Years Ended December 31, 2025 and 2024
 
NOTES TO FINANCIAL STATEMENTS
 
Note 1. Plan Description (Continued)
 
Principal and interest payments occur ratably through regular payroll deductions and over a period not to exceed five years unless the notes receivable were used to purchase a primary residence in which case the notes receivable term may exceed five years.
 
Plan Termination
 
Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. However, no such action may deprive any participant or beneficiary under the Plan of any vested benefit.
 
Note 2. Significant Accounting Policies
 
Basis of Presentation
 
The Plan's financial statements are prepared using the accrual basis of accounting, in conformity with accounting principles generally accepted in the United States of America ("GAAP").
 
Use of Estimates
 
GAAP requires management to make estimates and assumptions that affect the reported amounts of net assets and changes therein. Actual results could differ from those estimates.
 
Investments
 
The Plan’s investments are stated at fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.
 
Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date.
 
Notes Receivable from Participants
 
Notes receivable from participants are measured at their unpaid principal balance plus any accrued, but unpaid interest. Interest income is recorded on the accrual basis. Related fees are recorded as administrative expenses and are expensed when they are incurred. No allowance for credit losses has been recorded as of December 31, 2025 and 2024. If a participant ceases to make loan repayments and the plan administrator deems the participant loan to be in default, the participant loan balance is reduced, and a benefit payment is recorded.
 
Contributions
 
Contributions from Plan participants and the matching contributions from the Employer are recorded in the year in which the employee contributions are withheld from compensation.

NOTES TO FINANCIAL STATEMENTS
 
Note 2. Significant Accounting Policies (Continued)
 
Payment of Benefits
 
Benefits are recorded when paid.
 
Net Appreciation in Fair Value of Investments
 
Net appreciation in fair value of investments, as recorded in the accompanying statements of changes in net assets available for benefits, includes changes in the fair value of investments acquired, sold, or held during the year.
 
Administrative Fees
 
Certain administrative fees are paid by the Plan. All other fees, including professional fees, are paid by the Company. Expenses that relate solely to a participant are assessed against such participant as provided in the Plan agreement.
 
Note 3. Risks and Uncertainties
 
The Plan's investments include funds which invest in various types of investment securities and in various companies within various markets. Investment securities are exposed to several risks, such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants' account balances and the amounts reported in the Statements of Net Assets Available for Benefits and the Statements of Changes in Net Assets Available for Benefits.
 
Note 4. Tax Status
 
The IRS has determined and informed the Company by a letter dated December 12, 2016, that the Plan and related trust are designed in accordance with applicable sections of the IRC. The Plan has been amended since receiving the determination letter. However, the Plan administrator believes that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC.
 
GAAP requires plan management to evaluate tax positions taken by the Plan and recognize a tax liability if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. The Plan is subject to routine audits by tax jurisdictions; however, there are currently no audits for any tax periods in progress.

NOTES TO FINANCIAL STATEMENTS
 
Note 5. Party-In-Interest Transactions
 
Certain Plan investments are invested in the common stock of the Company. Investment transactions in employer securities qualify as exempt party-in-interest transactions. For the years ended December 31, 2025 and 2024, dividends of $433,912 and $494,211, respectively, were received by the Plan. The Plan held 422,930 and 491,661 shares valued at $16,473,118 and $17,390,020 on December 31, 2025 and 2024, respectively. For the year ended December 31, 2025, the Plan purchased 12,238 shares and sold 80,968 shares. For the year ended December 31, 2024, the Plan purchased 17,579 shares and sold 111,382 shares.
 
GWL&A performs services, sells products, and maintains certain investments of the Plan for which fees are charged to the Plan. Newport Trust Company serves as an independent fiduciary and investment manager for the Employer Stock Fund. Party-in-interest transactions also include notes receivable from participants. Certain Plan investments are held by Empower Trust Company, LLC who is trustee and recordkeeper for the Plan. Such transactions, while considered party-in-interest transactions under ERISA, are permitted under the provisions of the Plan and are specifically exempt from the prohibition of party-in-interest transactions.
 
Note 6. Fair Value Measurements
 
FASB ASC Topic 820, Fair Value Measurement ("ASC Topic 820"), establishes a framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under ASC Topic 820 are described as follows:
 
Level 1 Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access.
 
Level 2 Inputs to the valuation methodology include: quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; inputs other than quoted prices that are observable for the asset or liability; inputs that are derived principally from or corroborated by observable market data by correlation or other means. If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.
 
Level 3 Inputs to the valuation methodology are unobservable and significant to the fair value measurement.
 
The asset or liability's fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

Years Ended December 31, 2025 and 2024
 
NOTES TO FINANCIAL STATEMENTS
 
Note 6. Fair Value Measurements (Continued)
 
Following is a description of the valuation methodologies used for assets measured at fair value on a recurring basis. There have been no changes in the methodologies used on December 31, 2025 and 2024.
 
Common stock of Trustmark Corporation (Level 1): Valued at the closing price reported on the active market on which the individual securities are traded.
 
Mutual funds and self-directed brokerage accounts (Level 1): Valued at the NAV of shares held by the Plan at year-end. Mutual funds held by the Plan are open-end mutual funds that are registered with the Securities and Exchange Commission. These funds are required to publish their daily NAV and to transact at that price. The mutual funds held by the Plan are deemed to be actively traded. Self-directed brokerage accounts primarily consist of mutual funds, cash & cash equivalents, and exchange traded funds that are valued on the basis of readily determinable market prices.
 
Collective investment funds: Valued at NAV per unit, as determined by the trustee at year-end. The NAV is used as the practical expedient to estimate fair value.
 
Pooled separate account: Valued at NAV per unit, as determined by the trustee at year-end. The NAV is used as the practical expedient to estimate fair value.
 
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 the Plan believes its 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.
