Forward-looking Statements

This Form 8-K may contain statements, estimates or projections that constitute “forward-looking statements” pursuant to the safe harbor provisions of the U.S. federal securities laws. Generally, the words “believe,” “expect,” “intend,” “estimate,” “anticipate,” “project,” “will” and similar expressions identify forward-looking statements, which generally are not historical in nature. Forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from FIS’s historical experience and FIS’s present expectations or projections. These risks include, but are not limited to, changes in general economic, business and political conditions, developmental and conversion delays or disruptions inherent with new software products and technology, and risks of reduction in revenue from the elimination of existing and potential customers due to consolidation in or new laws or regulations affecting the banking, retail and financial services industries, the risk that the transaction described herein will not be completed or will not provide the expected benefits, or that FIS will not be able to achieve the synergies anticipated, changes in the growth rates of the markets for FIS solutions, and other risks detailed in FIS’s filings with the SEC, including the “Risk Factors” section of FIS’s Annual Report on Form 10-K for the year ended December 31, 2014, and subsequent Securities and Exchange Commission (“SEC”) filings. Investors and securityholders should not place undue reliance on forward-looking statements, which speak only as of the date they are made. FIS undertakes no obligation to publicly update or revise any forward-looking statements.
