2. Forward-Looking Statements And
Non-GAAP Financial Measures
2
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 contains financial information determined by methods other than in accordance with
GAAP. The Company’s management uses these non-GAAP financial measures in their analysis of the Company’s
performance. These measures typically adjust GAAP performance measures to exclude the effects of the amortization of
intangibles and include the tax benefit 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. Since the presentation of these GAAP performance
measures and their impact differ between companies, management believes presentations of these non-GAAP financial
measures provide useful supplemental information that is essential to a proper understanding of the operating results of
the Company’s core businesses. These non-GAAP disclosures should not be viewed as a substitute for operating results
determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may
be presented by other companies. Reconciliations of GAAP to non-GAAP disclosures are included as tables in the
Company’s press release dated April 27, 2017 and Annual Report on Form 10-K for the fiscal year ended December 31,
2016. Refer to the supplemental tables in the press release and Annual Report for these reconciliations.
