**<u>Item 5.02(b). Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.</u>**

On May 15, 2026, Wayne A. Stevens notified the Boards of Directors of Trustmark Corporation (the "Company") and its wholly owned subsidiary, Trustmark Bank (the "Bank"), of his intention to retire as President - Retail Banking of the Bank, effective as of July 3, 2026.

In connection with his retirement, the Human Resources Committee of the Company's Board of Directors approved the acceleration of vesting of his unvested time-based restricted stock units. Otherwise, Mr. Stevens will not receive any severance or other compensatory payments in connection with his departure, other than payment of earned but unpaid wages and other amounts due in the ordinary course and consistent with Company policy.

Trustmark appreciates the distinguished service of Mr. Stevens, who has served as an associate of Trustmark Bank beginning in 1986, and as an Executive Officer since 2009. Over the last 40 years, Mr. Stevens has made significant contributions to the growth and expansion of the organization.
