Pinnacle Financial Partners, Inc.

On January 1, 2026, Pinnacle completed its previously announced merger with Synovus and commenced an evaluation of the design and operating effectiveness of internal controls over financial reporting related to the combined entities. The evaluation of changes to processes, technology systems, and other components of internal control over financial reporting related to the Merger is ongoing.

Except for the changes made in connection with the Merger, there were no other changes to Pinnacle's internal control over financial reporting during the quarter ended June 30, 2026, that materially affected, or would be reasonably likely to materially affect, Pinnacle's internal control over financial reporting.

In connection with the preparation of this Quarterly Report on Form 10-Q, an evaluation was carried out by Pinnacle's management, with the participation of Pinnacle's Chief Executive Officer and Chief Financial Officer, of the effectiveness of Pinnacle's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Disclosure controls and procedures are designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and that such information is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosures. Based on that evaluation, Pinnacle's Chief Executive Officer and Chief Financial Officer have concluded that, as of June 30, 2026, Pinnacle's disclosure controls and procedures were effective.
