This act provides a safe harbor for such disclosure, which protects the companies from unwarranted litigation if actual results are different from management expectations. This release contains forward-looking statements which are not historical facts and reflects management’s current views and estimates of future economic circumstances, industry conditions, company performance, and financial results. These forward-looking statements are subject to a number of factors and uncertainties which could cause Hancock’s, Whitney’s or the combined company’s actual results and experience to differ from the anticipated results and expectations expressed in such forward-looking statements. Forward-looking statements speak only as of the date they are made and neither Hancock nor Whitney assumes any duty to update forward-looking statements. In addition to factors previously disclosed in Hancock’s and Whitney’s reports filed with the SEC, the following factors among others, could cause actual results to differ materially from forward-looking statements or historical performance: the possibility that the proposed transaction does not close when expected or at all because required regulatory or other approvals and other conditions to closing are not received or satisfied on a timely basis or at all; the terms of the proposed transaction may need to be modified to satisfy such approvals or conditions; the anticipated benefits from the proposed transaction such as it being accretive to earnings, expanding the combined company’s geographic presence and synergies are not realized in the time frame anticipated or at all as a result of changes in general economic and market conditions, interest and exchange rates, monetary policy, laws and regulations (including changes to capital requirements) and their enforcement, and the degree of competition in the geographic and business areas in which the companies operate; the ability to promptly and effectively integrate the businesses of Whitney and Hancock; reputational risks and the reaction of the companies’ customers to the transaction; diversion of management time on merger-related issues; changes in asset quality and credit risk; the inability to sustain revenue and earnings; changes in interest rates and capital markets; inflation; customer acceptance of our products and services; customer borrowing, repayment, investment and deposit practices; customer disintermediation; the introduction, withdrawal, success and timing of business initiatives; competitive conditions; and the impact, extent and timing of technological changes, capital management activities, and other actions of the Federal Reserve Board and federal and state banking regulators, and legislative and regulatory actions and reforms, including those associated with the Dodd-Frank Wall Street Reform and Consumer Protection Acts.
