NASHVILLE, TN AND COLUMBUS, GA, Nov. 6, 2025 – At separate meetings held today, shareholders of Pinnacle Financial Partners (Nasdaq/NGS: PNFP) and Synovus Financial Corp. (NYSE: SNV) approved the proposed merger of the two firms. At the Synovus special meeting, preliminary results showed approximately 91.5 percent of the votes cast were in favor of the combination, representing approximately 69.4 percent of the total number of outstanding shares entitled to vote as of Sept. 26, 2025, the record date for the Synovus special meeting. In preliminary results from the Pinnacle special meeting, approximately 92.2 percent of the votes cast were in favor of the combination, representing approximately 73.2 percent of the total number of outstanding shares entitled to vote as of Sept. 26, 2025, the record date for the Pinnacle special meeting.

“Today's shareholder vote with 92.2 percent of votes cast in favor of our merger with Synovus confirmed the value our management and board saw when we announced the deal,” said Pinnacle President and CEO Terry Turner, who will be chairman of the board at the combined company. “This is a major milestone on our way to building what we believe will be the peer leader in terms of sustainable revenue and EPS growth, two of the most highly correlated metrics with total shareholder return.”

“Shareholder approval at 91.5 percent of votes cast marks a defining moment in our path forward,” said Kevin Blair, Synovus CEO and incoming CEO of the post-merger Pinnacle Financial Partners. “We believe this partnership is strategically and financially compelling, positioning us to create the fastest-growing, most profitable and dynamic regional bank in the country. Synovus and Pinnacle share foundational principles: exceptional team member engagement combined with best-in-class client loyalty drives top-quartile financial and business performance. Together, we unite from a position of strength and momentum with a bright future.”

The merger is expected to close in the first quarter of 2026.
