“Safe Harbor” Statement Under the Private Securities Litigation Reform Act of 1995

This report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Congress passed the Private Securities Litigation Act of 1995 in an effort to encourage companies to provide information about their anticipated future financial performance. This act provides a safe harbor for such disclosure, which protects a company from unwarranted litigation if actual results are different from management expectations. This report reflects the current views and estimates of future economic circumstances, industry conditions, company performance, and financial results of the management of Renasant and KeyWorth. These forward-looking statements are subject to a number of factors and uncertainties which could cause Renasant’s, KeyWorth’s or the combined company’s actual results and experience to differ from the anticipated results and expectations expressed in such forward-looking statements, and such differences may be material. Forward-looking statements speak only as of the date they are made, and neither Renasant nor KeyWorth assumes any duty to update forward-looking statements. In addition to factors previously disclosed in Renasant’s reports filed with the SEC and those identified elsewhere in this report, these forward-looking statements include, but are not limited to, statements about (i) the expected benefits of the transaction between Renasant Bank and KeyWorth, including future financial and operating results, cost savings, enhanced revenues and the expected market position of the combined company that may be realized from the transaction, and (ii) Renasant’s and KeyWorth’s plans, objectives, expectations and intentions and other statements contained in this release that are not historical facts. Other statements identified by words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “targets,” “projects” or words of similar meaning generally are intended to identify forward-looking statements. These statements are based upon the current beliefs and expectations of Renasant’s and KeyWorth’s management and are inherently subject to significant business, economic and competitive risks and uncertainties, many of which are beyond their respective control. In addition, these forward-looking statements are subject to assumptions with respect to future business strategies and decisions that are subject to change. Actual results may differ from those indicated or implied in the forward-looking statements, and such differences may be material.

The following risks, among others, could cause actual results to differ materially from the anticipated results or other expectations expressed in the forward-looking statements: (1) the businesses of Renasant Bank and KeyWorth may not be integrated successfully or the integration may be more difficult, time-consuming or costly than expected; (2) the expected growth opportunities or costs savings from the transaction may not be fully realized or may take longer to realize than expected; (3) revenues following the transaction may be lower than expected as a result of losses of customers or other reasons; (4) deposit attrition, operating costs, customer loss and business disruption following the transaction, including difficulties in maintaining relationships with employees, may be greater than expected; (5) governmental approvals of the transaction may not be obtained on the proposed terms or expected timeframe; (6) KeyWorth’s shareholders may fail to approve the transaction; (7) the terms of the proposed transaction may need to be modified to satisfy such approvals or conditions; (8) reputational risks and the reaction of the companies’ customers to the transaction; (9) diversion of management time on merger related issues; (10) changes in asset quality and credit risk; (11) inflation; (12) the cost and availability of capital; (13) customer acceptance of the combined company’s products and services; (14) customer borrowing, repayment, investment and deposit practices; (15) the introduction, withdrawal, success and timing of business initiatives; (16) the impact, extent, and timing of technological changes; (17) severe catastrophic events in the companies’ respective geographic area; (18) a weakening of the economies in which the combined company will conduct operations may adversely affect its operating results; (19) the U.S. legal and regulatory framework, including those associated with the Dodd-Frank Wall Street Reform and Consumer Protection Act, could adversely affect the operating results of the combined company; (20) the interest rate environment may compress margins and adversely affect net interest income; and (21) competition from other financial services companies in the companies’ markets could adversely affect operations. Additional factors that could cause Renasant’s results to differ materially from those described in the forward-looking statements can be found in Renasant’s reports (such as Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K) filed with the SEC and available at the SEC’s website (www.sec.gov). All subsequent written and oral forward-looking statements concerning Renasant, KeyWorth or the proposed merger or other matters and attributable to Renasant, KeyWorth or any person acting on either of their behalf are expressly qualified in their entirety by the cautionary statements above. Renasant and KeyWorth do not undertake any obligation to update any forward-looking statement, whether written or oral, to reflect circumstances or events that occur after the date the forward-looking statements are made.
