CenterState Banks of Florida, Inc. Announces
First Quarter 2003 Earnings

     WINTER HAVEN, FL. – April 23, 2003 — CenterState Banks of Florida, Inc. (NASDAQ SYMBOL: CSFL) reported after tax earnings for the quarter ended March 31, 2003 of $527,000 or $0.15 per share versus $577,000 or $0.20 per share for the corresponding quarter in 2002.

     Ernest S. Pinner, President and CEO, stated that the decrease in total earnings is directly related to the compression in “spread” between the two periods, which was a result of the relatively historical low interest rate environment. (Spread is defined as the yield on interest earning assets less the cost of deposits and other interest bearing liabilities.) Mr. Pinner went on to state, that in addition to the spread compression, the decrease in earnings per share between the two periods is primarily the result of the issuance of 536,310 shares at December 31, 2002 related to the CenterState Bank acquisition. CenterState Bank is a new bank that has not yet produced positive quarterly earnings. The bank had a minimal loss (approximately $11 thousand) during the March 31, 2003 quarter. All per share data is presented on a diluted basis.

     Mr. Pinner further reported that the Company’s loan portfolio grew by $22.2 million (6.7%) during the quarter ended March 31, 2003. During this same period, deposits grew by $29.2 million (6.6%) and total assets grew by $31.1 million (6.3%). Mr. Pinner stated that the Company has been able to consistently produce double-digit annual loan growth rates, while at the same time maintaining credit quality.
