Iberiabank Corporation Merges Iberiabank and Iberiabank fsb

IBERIABANK Corporation (NASDAQ:IBKC) announced today plans to merge its two financial subsidiaries, expected to be effective in early October. IBERIABANK fsb, a federally-chartered thrift regulated by the Office of Thrift Supervision ('OTS'), will be merged into IBERIABANK, a commercial bank regulated by the Federal Reserve and the Louisiana Office of Financial Institutions ('OFI'). IBERIABANK Mortgage Company, currently a wholly-owned subsidiary of IBERIABANK fsb, will become a wholly-owned subsidiary of IBERIABANK.

The Company determined this action was in the best interests of its constituents, given the sweeping changes to the banking industry and recently enacted legislation and financial regulatory reform.

Daryl G. Byrd, President and Chief Executive Officer of the Company commented, 'The merger of these two subsidiaries will enhance our client experience and operating flexibility while maintaining our focus on high-quality local decision-making. In line with our commitment to exceptional service, we intend to make this a very seamless transition for our clients.' Byrd stated, 'Our 123-year-old IBERIABANK brand has become a recognizable mark of strength and stability in our local markets.'

Byrd continued, 'We maintain excellent relationships with all of our regulatory agencies, but this action will enhance the operating efficiency of the regulatory review process. We greatly appreciate the many years of support the OTS provided IBERIABANK fsb. The Federal Reserve Bank of Atlanta and the Louisiana OFI continue to provide our Company superior regulatory oversight and counsel as we continue to grow our bank in a high-quality manner.'

The Company believes operating one financial charter will also provide greater operational and balance sheet flexibility. Upon completion of the systems conversion, commercial and retail bank clients will have convenient access at all 140 IBERIABANK branch locations throughout the franchise, including Louisiana, Arkansas, Tennessee, Texas, Alabama and Florida. In addition, recently enacted legislation will provide future branch expansion flexibility consistent with benefits the thrift subsidiary enjoyed under the OTS charter. By operating under one brand name, the Company believes enhanced branding opportunities exist as well.
