News Release

Trustmark Corporation Announces First Quarter 2026 Financial Results

Performance reflects Continued Loan and Deposit Growth, Stable Credit Quality,

Expanded Fee Income, and Disciplined Noninterest Expense Management

JACKSON, Miss. – April 28, 2026 – Trustmark Corporation (NASDAQGS:TRMK) reported net income of $56.1 million in the first quarter of 2026, representing diluted earnings per share of $0.95. Trustmark’s performance during the first quarter produced a return on average tangible equity of 12.58% and a return on average assets of 1.20%. The Board of Directors declared a quarterly cash dividend of $0.25 per share payable June 15, 2026, to shareholders of record on June 1, 2026.

First Quarter Highlights

Loans held for investment (HFI) increased 1.5% linked-quarter and represented 88.3% of total deposits at March 31, 2026

Credit quality remained stable, net charge-offs represented 0.04% of average loans

Deposits expanded to $15.7 billion while the cost of total deposits declined 9 basis points linked-quarter to 1.63%

Noninterest income increased 2.7% linked-quarter, reflecting in part growth in mortgage banking revenue

Noninterest expense was unchanged linked-quarter, reflecting on-going expense management priorities

Duane A. Dewey, President and CEO, stated, “We continued to build upon the strong momentum from our record earnings in 2025 and are pleased with our strong performance in the first quarter of 2026. Our results reflect continued loan growth, stable credit quality, and an attractive core deposit base. In addition, we experienced continued growth in noninterest income while noninterest expense remained unchanged, reflecting our continued focus on expense management. Our associates have done a tremendous job of serving customers, building relationships, and demonstrating the value Trustmark can provide as a trusted financial partner.”

Balance Sheet Management

Loans HFI increased $203.7 million, or 1.5%, during the quarter and $636.5 million, or 4.8%, year-over-year

Deposits expanded $212.7 million, or 1.4%, linked-quarter and $631.8 million, or 4.2%, year-over-year

Maintained strong capital position with CET1 ratio of 11.70% and total risk-based capital ratio of 14.37%

Repurchased $19.8 million, or approximately 477 thousand shares, of common stock during the first quarter of 2026

Loans HFI totaled $13.9 billion at March 31, 2026, reflecting an increase of $203.7 million, or 1.5%, linked-quarter and $636.5 million, or 4.8%, year-over-year. The linked-quarter growth primarily reflected increases in commercial and industrial loans, construction, land development and other land loans, and other loans and leases offset in part by declines in other real estate secured loans and nonfarm, nonresidential loans. Trustmark’s loan portfolio remains well-diversified by loan type and geography.

Deposits totaled $15.7 billion at March 31, 2026, an increase of $212.7 million, or 1.4%, from the prior quarter, driven by seasonal increases in public deposits. Year-over-year, deposits expanded $631.8 million, or 4.2%, driven by growth in personal and commercial deposits. Trustmark continues to maintain a strong liquidity position as loans HFI represented 88.3% of total deposits at the end of the first quarter. Noninterest-bearing deposits represented 19.7% of total deposits at March 31, 2026. Interest-bearing deposit costs totaled 2.02% for the first quarter, a decrease of 14 basis points linked-quarter, while the cost of total deposits was 1.63%, a decrease of 9 basis points from the prior quarter.

During the first quarter, Trustmark repurchased $19.8 million, or approximately 477 thousand common shares, which represented 0.8% of shares outstanding at year end 2025. As previously announced, 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 continue to be implemented through open market repurchases or privately negotiated transactions. At March 31, 2026, Trustmark’s tangible equity to tangible assets ratio was 9.62%, while the total risk-based capital ratio was 14.37%. Tangible book value per share was $30.58 at March 31, 2026, an increase of 1.0% from the prior quarter and 10.1% from the prior year.

Credit Quality

Net charge-offs totaled $1.3 million, representing 0.04% of average loans in the first quarter

Net provision for credit losses was $2.7 million in the first quarter

Allowance for credit losses (ACL) represented 1.16% of loans HFI and 200.69% of nonaccrual loans, excluding individually analyzed loans at March 31, 2026

Nonaccrual loans totaled $96.7 million at March 31, 2026, up $12.3 million from the prior quarter primarily attributable to one commercial credit and $10.1 million year-over-year. Other real estate totaled $7.3 million, reflecting an increase of $359 thousand from the prior quarter and a decline of $1.0 million from the prior year. Collectively, nonperforming assets totaled $104.0 million, representing 0.73% of loans HFI and held for sale (HFS) at March 31, 2026.

The provision for credit losses for loans HFI was $4.7 million in the first quarter and was primarily attributable to loan growth, credit migration, and adjustments to the qualitative factors partially offset by changes in the macroeconomic forecast. The provision for credit losses for off-balance sheet credit exposures was a negative $1.9 million in the first quarter, primarily driven by a decrease in unfunded commitments and changes in the macroeconomic forecast partially offset by credit migration. Collectively, the provision for credit losses totaled $2.7 million in the first quarter compared to $1.2 million in the prior quarter and $5.3 million in the first quarter of 2025.

Allocation of Trustmark’s $160.4 million ACL on loans HFI represented 0.88% of commercial loans and 2.09% of consumer and home mortgage loans, resulting in an ACL to total loans HFI of 1.16% at March 31, 2026. Management believes the level of the ACL is commensurate with the credit losses currently expected in the loan portfolio.

Revenue Generation

Net interest income (FTE) totaled $163.5 million in the first quarter, down 1.4% linked-quarter

Net interest margin totaled 3.81% in the first quarter, unchanged from the prior quarter

Noninterest income totaled $42.3 million, up 2.7% from the prior quarter, representing 20.9% of total revenue in the first quarter

Revenue in the first quarter totaled $202.9 million, a seasonal decrease of 0.6% from the prior quarter and an increase of 4.2% from the same quarter in the prior year. The linked-quarter decrease primarily reflects lower net interest income offset in part by higher noninterest income while the year-over-year increase is attributed to higher net interest income.

Net interest income (FTE) in the first quarter totaled $163.5 million, resulting in a net interest margin of 3.81%, unchanged from the prior quarter. The stable net interest margin reflected the linked-quarter decrease in the yield for the loans HFI and HFS portfolio which was offset by the increase in the yield on the securities portfolio and the decrease in the costs of interest-bearing liabilities.

Noninterest income in the first quarter totaled $42.3 million, an increase of $1.1 million, or 2.7%, from the prior quarter and a decrease of $239 thousand, or 0.6%, year-over-year. The linked-quarter increases in other, net and mortgage banking, net were offset in part by lower wealth management revenue and seasonal declines in bank card and other fees and service charges on deposit accounts.

Wealth management revenue in the first quarter totaled $10.4 million, a decrease of $740 thousand, or 6.6%, from the prior quarter and an increase of $850 thousand, or 8.9%, year-over-year. The linked-quarter decline reflected reduced brokerage revenue offset in part by increased trust and investment management revenue. The year-over-year growth reflected increased trust management revenue and brokerage revenue.

Mortgage loan production in the first quarter totaled $375.1 million, down 4.6% from the prior quarter and up 17.7% year-over-year. Mortgage banking revenue totaled $8.9 million in the first quarter, an increase of $1.4 million, or 18.7%, linked-quarter and $163 thousand, or 1.9%, year-over-year. The linked-quarter increase was principally attributable to reduced servicing asset amortization and improvement in net hedge ineffectiveness.

Service charges on deposit accounts totaled $10.7 million in the first quarter, reflecting a seasonal decrease of $530 thousand, or 4.7%, from the prior quarter. Bank card and other fees totaled $8.0 million in the first quarter, down $658 thousand from the prior quarter due principally to a seasonal decline in interchange income as well as a decline in miscellaneous other bank fees. Year-over-year, bank card and other fees increased $324 thousand, reflecting increased customer derivative revenue offset in part by lower miscellaneous other bank fees.

Other, net totaled $4.4 million in the first quarter, an increase of $1.6 million from the prior quarter primarily attributable to higher partnership investment revenue. Year-over-year other, net declined $1.6 million due to a gain on the sale of a bank office facility of $2.4 million in the first quarter of 2025 offset in part by increased partnership investment revenue.

Noninterest Expense

Noninterest expense totaled $132.2 million, unchanged from the prior quarter

Salaries and employee benefits expense declined $837 thousand, or 1.1%, linked-quarter

Total services and fees increased $575 thousand, or 2.1%, linked-quarter

Noninterest expense in the first quarter totaled $132.2 million, unchanged from the prior quarter and an increase of $8.1 million, or 6.6%, year-over-year. Salaries and employee benefits expense totaled $74.2 million in the first quarter, a decline of $837 thousand, or 1.1%, linked-quarter and an increase of $5.8 million, or 8.4%, year-over-year. The linked-quarter decline reflected reductions in incentives and commissions which were offset in part by increased employee benefits expense and a seasonal increase in payroll taxes.

Services and fees in the first quarter totaled $27.9 million, an increase of $575 thousand, or 2.1%, from the prior quarter and $1.7 million, or 6.5%, year-over-year. The linked-quarter increase is attributable principally to data processing, communications, and advertising expense offset in part by reduced outsourcing and professional fees. Total other expense was $15.1 million, an increase of $138 thousand, or 0.9%, linked-quarter and a decrease of $430 thousand, or 2.8%, year-over-year. The linked-quarter increase is attributable to other miscellaneous expense offset in part by lower other real estate expense, net and loan expense.

NOTES TO CONSOLIDATED FINANCIALS

March 31, 2026

($ in thousands)

(unaudited)

Note 1 – Subordinated Notes Payable

During the fourth quarter of 2025, Trustmark agreed to issue and sell $175.0 million aggregate principal amount of its 6.00% Fixed-to-Floating Rate Subordinated Notes (the Notes) due December 1, 2035. The 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 existing $125.0 million of aggregate principal amount of its outstanding 3.625% Fixed-to-Floating Rate Subordinated Notes due December 1, 2030 plus accrued interest, and for general corporate purposes.

The Notes are unsecured obligations and are subordinated in right of payment to all of Trustmark’s existing and future senior indebtedness, whether secured or unsecured. The Notes are obligations of Trustmark only and are not obligations of, and are not guaranteed by, any of its subsidiaries, including TB. The Notes qualify as Tier 2 capital for Trustmark.

At March 31, 2026, the net unamortized, unrealized loss included in accumulated other comprehensive income (loss) in the accompanying balance sheet for securities held to maturity transferred from securities available for sale totaled $34.1 million.

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, direct obligations of government agencies and GSE-backed obligations. None of the securities owned by Trustmark are collateralized by assets which are considered sub-prime. Furthermore, outside of stock ownership in the Federal Home Loan Bank of Dallas and Federal Reserve Bank, Trustmark does not hold any other equity investment in a GSE.

Note 4 – Yields on Earning Assets and Costs of Interest-Bearing Liabilities (continued)

The net interest margin remained flat when compared to the fourth quarter of 2025, totaling 3.81% for the first quarter of 2026, as the decrease in the yield for the loans held for investment and held for sale portfolio was offset by the increase in the yield on the securities portfolio and the decrease in the costs of interest-bearing liabilities.

Note 5 – Mortgage Banking

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 offsets the changes in fair value of mortgage servicing rights (MSR) attributable to interest rates. These transactions are considered freestanding derivatives that do not otherwise qualify for hedge accounting under generally accepted accounting principles (GAAP). Changes in the fair value of these exchange-traded derivative instruments, including administrative costs, are recorded in noninterest income in mortgage banking, net and are offset by the changes in the fair value of the MSR. The MSR fair value represents the present value of future cash flows, which among other things includes decay and the effect of changes in interest rates. Ineffectiveness of hedging the MSR fair value is measured by comparing the change in value of hedge instruments to the change in the fair value of the MSR asset attributable to changes in interest rates and other market driven changes in valuation inputs and assumptions. The impact of this strategy resulted in a net negative hedge ineffectiveness of $96 thousand during the first quarter of 2026.

Note 7 – 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.

NOTES TO CONSOLIDATED FINANCIALS

March 31, 2026

($ in thousands)

(unaudited)

Note 7 – Non-GAAP Financial Measures (continued)

Trustmark discloses certain non-GAAP financial measures because Management uses these measures for business planning purposes, including to manage Trustmark’s business against internal projected results of operations and to measure Trustmark’s performance. Trustmark views these as measures of our core operating business, which exclude the impact of the items detailed below, as these items are generally not operational in nature. These non-GAAP financial measures also provide another basis for comparing period-to-period results as presented in the accompanying selected financial data table and the 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 consolidated financial statements and the notes related thereto in their entirety, and not to rely on any single financial measure.

The following table presents pre-provision net revenue (PPNR) during the periods presented:
