TRUSTMARK CORPORATIO

Item 8.01. Other Events.

--------------------------------------------------------------------------------

Trustmark Corporation (the "Company") today announced that, effective January 1,
2022, the Board of Directors has authorized a new stock repurchase program under
which up to $100,000,000 of its outstanding common shares may be acquired
through December 31, 2022. The adoption of the Company's share repurchase
program follows the notification of the new share repurchase program by the
Company to the Board of Governors of the Federal Reserve System. This
authorization replaces the Company's prior stock repurchase program, which will
expire in accordance with its terms on December 31, 2021.

The shares may be purchased from time to time at prevailing market prices,
through open market or privately negotiated transactions, depending on market
conditions. There is no guarantee as to the number or aggregate market value of
shares that may be repurchased by the Company, and the Company may discontinue
purchases at any time at management's discretion. As of October 29, 2021, the
Company had 62,450,372 shares outstanding.
