EXPLANATORY NOTE/DEREGISTRATION OF SECURITIES

This post-effective amendment (this "Post-Effective Amendment") relates to the Registration Statement on Form S-3 (the "Registration Statement") previously filed by Pinnacle Financial Partners, Inc., a Tennessee corporation (the "Registrant"), with the Securities and Exchange Commission (the "SEC") on March 4, 2016 (Registration No. 333-209925), which registered 860,470 shares of the Registrant's common stock, $1.00 par value per share ("common stock"), for offer and sale from time to time by certain selling shareholders named therein (the "selling shareholders").

The Registrant entered into an Investor Rights Agreement (the "Agreement") by and among the Registrant and the selling shareholders on March 1, 2016 and agreed to register for offer and resale on a Form S-3 registration statement certain shares of the Registrant's common stock issued to the selling shareholders. The Registrant's obligations under the Agreement with respect to the registration of the shares of the Registrant's common stock have expired.

The Registrant, by filing this Post-Effective Amendment, hereby terminates the effectiveness of the Registration Statement and removes from registration any and all shares of the Registrant's common stock registered but unsold or otherwise unissued under the Registration Statement as of the date hereof. This filing is made in accordance with an undertaking made by the Registrant in Part II of the Registration Statement to remove from registration by means of a post-effective amendment any shares of its common stock that had been registered for issuance but remain unsold at the termination of the offering.
