Pinnacle Financial Partners Announces 2:1 Stock Split

NASHVILLE, Tenn., July 20, 2006 - Pinnacle Financial Partners Inc. (Nasdaq/NGS: PNFP) today announced that its board of directors has approved a two-for-one stock split. The stock split will be effected in the form of a 100 percent stock dividend, with the new shares being distributed on or about August 11, 2006, to shareholders of record at the close of business on July 31, 2006. Pinnacle had 15,370,116 common shares outstanding as of June 30, 2006.

"This decision by our board of directors is reflective of the excellent financial performance of our firm and the confidence we all share in the growth plans for our company," said M. Terry Turner, Pinnacle's president and chief executive officer. "We also believe the split will make the stock more widely available to current and potential investors."

This is the second 2:1 stock split in Pinnacle's 5-1/2-year history. Since the first stock split on May 11, 2004, the firm's stock price has increased 111 percent from May 11, 2004, through July 19, 2006. Between 2001 and 2006, the firm's stock was the eighth-best performing stock of all companies based in Tennessee, with a 914 percent cumulative return over the five-year period ending June 30, 2006.
