Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

CenterState Banks, Inc. (the “Company” or “CenterState”) announced that it has closed and consolidated four branch offices during the first quarter.

Three of the four branch locations acquired pursuant to the January 20, 2012 FDIC assisted acquisition of Central Florida State Bank in Belleview, Florida (“Central FL”) were closed and consolidated into nearby existing CenterState branches. CenterState exercised its option not to purchase the related branch real estate from the FDIC. The fourth Central FL branch acquired will continue to operate until certain physical modifications have been completed in a nearby existing CenterState branch, at which time it will also be consolidated. Management expects this process to be completed in the second quarter.

In addition to the Central FL branches discussed above, the Company also closed and consolidated a small branch office it acquired in a third quarter 2010 FDIC assisted transaction in Clewiston, Florida.

The Company continues to evaluate other existing branches as well as support staff and other back room operations as it works toward greater efficiency and further reduction in operating expenses.

In accordance with General Instruction B.2 of Form 8-K, the information in this Current Report on Form 8-K shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liability of that section, and shall not be incorporated by reference into any registration statement or other document filed under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.
