The Volunteer State is the home of Elvis Presley and the Grand Old Opry, former Vice President Al Gore, presidential candidate Fred Thompson, and the NFL's Tennessee Titans. Economically, Tennessee is the home of textiles, cotton, cattle, and electricity production, as well as mega corporations such as FedEx Corp. (NYSE: FDX) and International Paper Co. (NYSE: IP). And it is also the home of four companies from Fortune's 2007 list of the fastest growing public companies in the U.S.: Psychiatric Solutions Inc. (NASDAQ: PSYS), Pinnacle Financial Partners (NASDAQ: PNFP), Miller Industries Inc. (NYSE: MLR), and First Acceptance Corp. (NYSE: FAC).

At number 49 on Fortune's list was Psychiatric Solutions (PSI), the Franklin-based health care provider, which has grown in part through acquisitions. It has 900 psychiatric hospitals in 30 states, and operates in-patient facilities for other hospitals and government organizations. PSI's three-year revenue growth was 50%; three-year earnings per share growth at 76%. In July, PSI reported a record second quarter and a Lehman Brothers analyst expects PSI to meet or beat expectations in the current quarter. The consensus of analysts surveyed by Thomson Financial is that PSI is a buy, but Standard & Poor's is among those that consider PSI a strong buy. The share price was $39.90 on at the close on Friday.

Nashville-based Pinnacle Financial Partners is the holding company for Pinnacle National Bank, and holds assets of more than $2 billion. Pinnacle's three-year revenue growth was 81%, and its three-year earnings per share growth was 46%. Despite a strong second quarter report, the share price dropped to a 52-week low of $21.62 in August, but has bounced back since to $30.63 at the close on Friday. In September, a Pinnacle director bought 5,000 common shares of PNFP, and Pinnacle was among southern regional banks considered good bets despite the current credit climate. Analysts surveyed by Thomson Financial consider Pinnacle Financial a buy.
