IBERIABANK Corporation Announces Completed Acquisition Of Pulaski Investment Corporation

Lafayette, Louisiana – IBERIABANK Corporation (NASDAQ: IBKC), announced completion of the acquisition of Pulaski Investment Corporation, based in Little Rock, Arkansas.

The shareholders of Pulaski Investment Corporation unanimously approved the acquisition by IBERIABANK Corporation. The transaction was completed after the close of business on January 31, 2007. Pulaski Bank and Trust Company will retain its current name and operate as a wholly-owned separate subsidiary of IBERIABANK Corporation. IBERIABANK Corporation recently elected to become a financial holding company. A bank holding company that qualifies as a financial holding company may engage in a broader range of financial activities.

The Company anticipates completion of operating systems and branch conversions over the next two months.

Daryl G. Byrd, President and Chief Executive Officer of IBERIABANK Corporation added, “Our expansion into Arkansas begins. This acquisition also expands our banking franchise into the dynamic suburbs of the Memphis market. Our business becomes more diversified with the largest independent title insurance agency in Arkansas and a nationally recognized high-quality credit card operation. In addition, our annual mortgage production level climbs to nearly $1 billion with mortgage banking operations throughout Arkansas, Memphis, St. Louis, Dallas, and other vibrant markets. We are very excited about our growth prospects associated with this acquisition.”

James C. East, Chairman of Pulaski, commented, “The culmination of the acquisition is another important step forward. We are particularly excited about the opportunities this partnership brings our franchise – exceptional opportunities for our clients, our employees and our communities.”

Hunter East, Chief Executive Officer of Pulaski, commented, “IBERIABANK and Pulaski are very unique, but complementary, organizations. We are delighted to have affiliated with such a fine group of experienced and client-focused bankers. I am personally excited about my continued involvement with the organization and look forward to aiding in the expansion of the franchise.”
