IBERIABANK Corporation Announces Agreement to Acquire Florida Bank Group, Inc.

LAFAYETTE, LOUISIANA AND TAMPA, FLORIDA — IBERIABANK Corporation (NASDAQ: IBKC) (“IBKC”), holding company of the 127-year-old IBERIABANK (www.iberiabank.com) and Florida Bank Group, Inc. (“Florida Bank Group”) (www.flbank.com) jointly announced today the signing of a definitive agreement for IBKC to acquire Florida Bank Group via merger. The proposed merger of Florida Bank Group with and into IBKC has been approved by the Board of Directors of each company and is expected to close in the first quarter of 2015. Completion of the transaction is subject to customary closing conditions, including the receipt of required regulatory approvals and the approval of Florida Bank Group’s shareholders.

Susan Martinez, President and Chief Executive Officer of Florida Bank Group, commented, “Our organization has undergone tremendous change and we are very proud of our people and the strong teamwork they exhibited over the last several years. We faced a very challenging operating environment and executed very well on our plan. I am particularly proud of our effective and efficient delivery of high-quality client service. We are very excited to be joining forces with IBERIABANK and together grow to become the leading financial institution serving our clients and communities.”

Daryl G. Byrd, President and Chief Executive Officer of IBKC, commented, “Susie Martinez, her team, and the Florida Bank Group Board of Directors have done an outstanding job in rebuilding their organization and preparing for future client growth opportunities. We are very excited to be teaming up with them and entering the Tampa Bay market in such a high-quality manner. The Tampa Bay area has a very strong concentration of commercial and industrial companies, which is a segment of banking in which our company excels. With the addition of Florida Bank Group, we will extend our brand throughout the west coast of central and south Florida and into Jacksonville in northeast Florida.”

Under the terms of the merger agreement, shareholders of Florida Bank Group will receive a combination of cash and IBKC common stock. Florida Bank Group common shares are assumed to total approximately 5,051,745 shares at closing, assuming approximately 2,471,745 common shares outstanding, approximately 2,480,000 common shares associated with the conversion of the convertible preferred stock into common shares, and 100,000 warrants outstanding that are assumed to be exercised prior to closing.

IBKC currently estimates annual pre-tax expense reductions associated with the transaction will be approximately 31% of Florida Bank Group’s run-rate expenses in 2014. The expense savings are estimated to be fully achieved, on a run-rate basis, within six months of closing. Estimated acquisition and conversion related costs (including lease termination costs) are estimated to be approximately $20 million on a pre-tax basis. Assuming synergies are fully phased in and excluding acquisition and conversion related costs, the transaction is expected to be neutral to IBKC’s 2015 fully diluted earnings per share (“EPS”) and mildly accretive thereafter.

The transaction is expected to slightly reduce IBKC’s capital ratios, and be less than 1% dilutive to tangible book value per share on a pro forma basis at closing. The tangible book value dilution is anticipated to be earned back in two years. The estimated internal rate of return for the transaction is expected to be greater than 20%, and, therefore, in excess of IBKC’s cost of capital.

Florida Bank Group Bank has 13 branches in Tampa Bay area (eight offices), Jacksonville area (three offices), Tallahassee (one office), and Sarasota (one office). At June 30, 2014, Florida Bank Group had:
