SouthState Bank Corp

Evaluation of Disclosure Controls and Procedures

SouthState’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of SouthState’s disclosure controls and procedures as of June 30, 2026, in accordance with Rule 13a-15 of the Securities Exchange Act of 1934. We applied our judgment in the process of reviewing these controls and procedures, which, by their nature, can provide only reasonable assurance regarding our control objectives. Based upon that evaluation, our Chief Executive Officer and the Chief Financial Officer concluded that SouthState’s disclosure controls and procedures as of June 30, 2026, were effective to provide reasonable assurance regarding our control objectives.

The design of any system of controls and procedures is based in part upon certain assumptions about the likelihood of future events. There can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.
