Safe Harbor And Non-GAAP Financial Measures Safe Harbor To the extent that statements in this PowerPoint presentation relate to future plans, objectives, financial results or performance of IBERIABANK Corporation, these statements are deemed to be forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements, which are based on management’s current information, estimates and assumptions and the current economic environment, are generally identified by the use of the words “plan”, “believe”, “expect”, “intend”, “anticipate”, “estimate”, “project” or similar expressions. The Company’s actual strategies, results and financial condition in future periods may differ materially from those currently expected due to various risks and uncertainties. Forward-looking statements are subject to numerous assumptions, risks and uncertainties that change over time and could cause actual results or financial condition to differ materially from those expressed in or implied by such statements. Consequently, no forward-looking statement can be guaranteed. Except to the extent required by applicable law or regulation, the Company undertakes no obligation to revise or update publicly any forward-looking statement for any reason. This PowerPoint presentation supplements information contained in the Company’s earnings release dated October 18, 2019, and should be read in conjunction therewith. The earnings release may be accessed on the Company’s web site, www.iberiabank.com, under “Investor Relations” and then “Financial Information” and then “Press Releases.” Non-GAAP Financial Measures This PowerPoint presentation contains financial information determined by methods other than in accordance with GAAP. The Company’s management uses core non-GAAP financial metrics (“Core”) in their analysis of the Company’s performance to identify core revenues and expenses in a period that directly drive operating net income in that period. These Core measures typically adjust GAAP performance measures to exclude the effects of the amortization of intangibles and include the tax benefits associated with revenue items that are tax-exempt, as well as adjust income available to common shareholders for certain significant activities or transactions that in management’s opinion can distort period-to-period comparisons of the Company’s performance. Reference is made to “Non-GAAP Financial Measures” and “Caution About Forward Looking Statements” in the earnings release which also apply to certain disclosures in this PowerPoint presentation. 2
