EXHIBIT 99.1 IBERIABANK CORPORATION AND ACADIANA BANCSHARES, INC. PRO FORMA COMBINED FINANCIAL INFORMATION (unaudited) The following unaudited pro forma combined financial statements combine the historical consolidated balance sheets of IBERIABANK Corporation (the "Company" or "IBKC") and Acadiana Bancshares, Inc. ("Acadiana") as if the merger transaction described in the accompanying notes and consummated at the close of business on February 28, 2003 had happened at the close of business on December 31, 2002. The unaudited Pro Forma Combined Balance Sheet is based upon the audited consolidated balance sheets of the Company and Acadiana as of December 31, 2002. The unaudited Pro Forma Combined Statement of Income for the year ended December 31, 2002 presents the combined results of operations of the Company and Acadiana as if the merger had been effective at the beginning of the period presented and is based on the audited consolidated results of operations of the Company and Acadiana for the year ended December 31, 2002. The resolution of the pending matters pertaining to the assets and liabilities of Acadiana will affect the allocation of the purchase price. An increase in the unallocated portion of the purchase price remaining after fair value adjustments will result in a greater final allocation to goodwill which will have a corresponding reduction in tangible common equity. A decrease in the unallocated portion of the purchase price remaining after fair value adjustments will have the opposite effect. Accordingly, the final pro forma combined amounts will differ from those set forth in the unaudited pro forma combined financial statements. It is not expected that any change would be of a material nature. The pro forma financial statements are presented for comparative purposes only and are not necessarily indicative of the combined financial position or results of operations in the future. The pro forma financial statements are also not necessarily indicative of the combined financial position or results of operations that would have been realized had the merger been consummated during the periods or as of the dates for which the pro forma financial statements are presented. The pro forma combined statements are simply arithmetical combinations of the separate results of both entities and do not reflect potential cost savings, revenue enhancements or balance sheet restructuring.

IBERIABANK CORPORATION AND ACADIANA BANCSHARES, INC. NOTES TO PRO FORMA COMBINED FINANCIAL STATEMENTS (unaudited) NOTE 1 - BASIS OF PRESENTATION The unaudited pro forma combined balance sheet combines the historical consolidated balance sheets of IBKC and Acadiana as if the merger had been effective on December 31, 2002. The unaudited pro forma combined statement of income for the year ended December 31, 2002 presents the combined results of operations as if the merger had been effective at the beginning of the period presented. Certain amounts in the historical financial statements of Acadiana have been reclassified in the unaudited pro forma combined financial statements to conform to IBKC's historical financial statements. The merger is accounted for as a purchase. In accordance with Financial Accounting Standards Board Statements No. 141 and No. 142, assets and liabilities of Acadiana are adjusted to their estimated fair value and combined with the recorded values of the assets and liabilities of IBKC. Applicable income tax effects of such adjustments are included as a component of IBKC's net deferred tax asset. Adjustments are made to reflect the recording of intangibles as well as to eliminate any intangible balances previously recorded by Acadiana in accordance with the purchase method of accounting. The pro forma combined financial statements are presented for comparative purposes only and are not necessarily indicative of the combined financial position or results of operations in the future. The pro forma combined financial statements are also not necessarily indicative of the combined financial position or results of operations that would have been realized had the merger been consummated during the periods or as of the dates for which the pro forma financial statements are presented. The combined company expects to achieve merger benefits resulting from cost savings, balance sheet restructuring and revenue enhancements, which are not reflected in the pro forma combined statements. No assurance can be given with respect to the ultimate level of expense savings or revenue enhancements The finalization of estimates pertaining to the assets and liabilities of Acadiana may affect the allocation of the purchase price, the actual amount of goodwill and consequently, future net income. However, any such finalization of estimates is not expected to have a significant impact on the ultimate amount of goodwill The unaudited pro forma combined financial statements and the accompanying notes have been prepared from, and should be read with the accompanying footnotes and also in conjunction with the historical consolidated financial statements and notes thereto of the Company filed in its Annual Report on Form 10-K for the year ended December 31, 2002 and of Acadiana as filed on the Company's Form 8-K dated March 3, 2003. NOTE 2 - PURCHASE PRICE The purchase price is based on exchanging $7.88 in cash and .7919 shares of IBKC common stock for each outstanding Acadiana share at the fair market price of $39.30 per share of IBKC common stock.
