Trustmark Corporation plans to raise new long-term debt and refinance existing notes.
Rhea-AI Filing Summary
Trustmark Corporation plans to raise new long-term debt and refinance existing notes. The company agreed to issue and sell $175,000,000 of 6.00% Fixed-to-Floating Rate Subordinated Notes due 2035, with an underwriting discount of 1.1%, resulting in approximately $173.1 million of net proceeds before expenses. Trustmark intends to use the proceeds to repay $125,000,000 of its outstanding 3.625% Fixed-to-Floating Rate Subordinated Notes due 2030 plus accrued interest, and for general corporate purposes. The new notes pay a fixed 6.00% interest rate until December 1, 2030, then switch to a floating rate based on a Benchmark rate, expected to be Three-Month Term SOFR, plus 260 basis points until maturity in 2035. The offering is expected to close on November 20, 2025, subject to customary conditions, and the notes are unsecured, subordinated obligations in Trustmark’s capital structure.

Insights
Trustmark refinances subordinated debt, extending maturity and modestly increasing coupon.
Trustmark Corporation is issuing $175,000,000 of 6.00% Fixed-to-Floating Rate Subordinated Notes due 2035. Net proceeds of about $173.1 million are earmarked to repay $125,000,000 of 3.625% Fixed-to-Floating Rate Subordinated Notes due 2030 and for general corporate purposes. This shifts part of its subordinated debt stack further out on the maturity curve.
The new notes carry a higher fixed coupon of 6.00% until December 1, 2030, then convert to a floating rate equal to a Benchmark, expected to be Three-Month Term SOFR, plus 260% basis points until December 1, 2035. This structure introduces some interest rate sensitivity after 2030, while locking in current funding costs for the initial period.
The notes are unsecured and subordinated, ranking below Senior Indebtedness and effectively behind liabilities of Trustmark Bank and other subsidiaries, but ahead of certain junior subordinated debentures. The offering is expected to close on November 20, 2025, subject to customary conditions, so the actual impact will depend on final closing and how the general corporate purposes portion is deployed.

| Item 1.01. | Entry Into a Material Definitive Agreement. |
On November 17, 2025, Trustmark Corporation (the “Company”) agreed to issue and sell (the “Offering”) $175,000,000 aggregate principal amount of its 6.00% Fixed-to-Floating Rate Subordinated Notes due 2035 (the “Notes”), pursuant to an Underwriting Agreement, dated as of November 17, 2025 (the “Underwriting Agreement”), with Keefe, Bruyette & Woods and Goldman Sachs & Co. LLC as underwriters. The Offering will be completed pursuant to the prospectus filed with the Securities and Exchange Commission as part of the Company’s Registration Statement on Form S-3 (File Number: 333-291572), as supplemented by a preliminary prospectus supplement, a final prospectus supplement and free writing prospectuses, each dated November 17, 2025. The Notes will be sold at an underwriting discount of 1.1%, resulting in net proceeds to the Company of approximately $173.1 million before deducting offering expenses. The Company intends to use the net proceeds from the Offering, after the payment of offering expenses, to repay $125,000,000 aggregate principal amount of its outstanding 3.625% Fixed-to-Floating Rate Subordinated Notes due 2030 plus accrued interest, and for general corporate purposes. The Offering is expected to close on November 20, 2025, subject to satisfaction of customary closing conditions.
The Notes will be issued under the Subordinated Indenture, dated as of November 25, 2020 (the “Subordinated Indenture”), between the Company and Wilmington Trust, National Association, as trustee (the “Trustee”), as supplemented by the Second Supplemental Indenture, to be dated as of November 20, 2025 (the “Second Supplemental Indenture,” and, together with the Subordinated Indenture, the “Indenture”).
From and including the date of issuance to, but excluding, December 1, 2030 or the date of earlier redemption, the Notes will bear interest at a fixed rate of 6.00% per year, payable semi-annually in arrears on June 1 and December 1 of each year, commencing on June 1, 2026. Thereafter, from and including December 1, 2030, to, but excluding, the maturity date, December 1, 2035, or the date of earlier redemption, the Notes will bear interest at a floating rate per year equal to the Benchmark rate, which is expected to be Three-Month Term SOFR (each as defined in the Indenture), 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. Notwithstanding the foregoing, if the Benchmark rate is less than zero, then the Benchmark rate shall be deemed to be zero.
The Notes, when issued, will be the Company’s unsecured, subordinated obligations and will (i) rank junior in right of payment and upon liquidation to any of the Company’s existing and future Senior Indebtedness (as defined in the Indenture), whether secured or unsecured; (ii) rank equal in right of payment and upon liquidation with any of the Company’s existing and future subordinated indebtedness the terms of which provide that such indebtedness ranks equally with promissory notes, bonds, debentures and other evidences of indebtedness of types that include the Notes; (iii) rank senior in right of payment and upon liquidation with the Company’s existing junior subordinated debentures underlying outstanding trust preferred securities and any indebtedness the terms of which provide that such indebtedness ranks junior to promissory notes, bonds, debentures and other types of indebtedness that include the Notes; and (iv) be effectively subordinated to all of the existing and future indebtedness, deposits and other liabilities of Trustmark Bank and the Company’s other current and future subsidiaries, including, without limitation, Trustmark Bank’s liabilities to depositors in connection with the deposits in Trustmark Bank, its liabilities to general creditors and its liabilities arising during the ordinary course or otherwise.
The Notes may be redeemed at the Company’s option under certain circumstances, as described in the Indenture.
The foregoing summary of the terms of the Underwriting Agreement, the Indenture and the Notes does not purport to be complete and is subject to, and qualified in its entirety by, the full text of (i) the Underwriting Agreement, (ii) the Subordinated Indenture, (iii) the form of Second Supplemental Indenture, and (iv) the form of the Notes, each of which is attached hereto as an exhibit and is incorporated herein by reference.
