FORWARD-LOOKING STATEMENTS

Certain of the matters discussed in this communication may constitute forward-looking statements. You can identify forward-looking statements because they contain words such as “believes,” “expects,” “may,” “will,” “should,” “seeks,” “intends,” “plans,” “estimates,” or “anticipates” or similar expressions which concern strategy, plans, projections or intentions. Examples of forward-looking statements include, but are not limited to, all statements made relating to revenue, earnings before net interest expense, income taxes, depreciation and amortization, earnings, margins, growth rates and other financial results for future periods. By their nature, forward-looking statements speak only as of the date they are made; are not statements of historical fact or guarantees of future performance; and are subject to risks, uncertainties, assumptions or changes in circumstances that are difficult to predict or quantify. In addition to factors previously disclosed in First Data’s and Fiserv’s reports filed with the SEC and those identified elsewhere in this communication, the following factors, among others, could cause actual results to differ materially from forward-looking statements or historical performance: the occurrence of any event, change or other circumstances that could give rise to the right of one or both of First Data and Fiserv to terminate the definitive merger agreement between First Data and Fiserv; the outcome of any legal proceedings that have been or may be instituted against First Data, its stockholders or directors or Fiserv, its shareholders or directors; the ability to obtain regulatory approvals and satisfy other closing conditions to the proposed merger in a timely manner or at all, including the risk that regulatory approvals required for the proposed merger are not obtained or are obtained subject to conditions that are not anticipated or that are material and adverse to First Data’s or Fiserv’s business; a delay in closing the proposed merger; the ability to obtain approval by First Data stockholders and Fiserv shareholders on the expected terms and schedule or at all; difficulties and delays in integrating the First Data and Fiserv businesses, including with respect to implementing systems to prevent a material security breach of any internal systems or to successfully manage credit and fraud risks in business units; failing to fully realizing anticipated cost savings and other anticipated benefits of the proposed merger; business disruptions from the proposed merger that may harm First Data’s or Fiserv’s business, including current plans and operations; potential adverse reactions or changes to business relationships resulting from the announcement or completion of the proposed merger, including as it relates to First Data’s or Fiserv’s ability to successfully renew existing client or supplier contracts on favorable terms or at all and obtain new clients or suppliers; certain restrictions during the pendency of the proposed merger that may impact First Data’s or Fiserv’s ability to pursue certain business opportunities or strategic transactions; the ability of First Data or Fiserv to retain and hire key personnel; uncertainty as to the long-term value of the common stock of Fiserv following the completion of the proposed merger; the continued availability of capital and financing following the completion of the proposed merger; the business, economic and political conditions in the markets in which First Data and Fiserv operate; the impact of new or changes in current laws, regulations, credit card association rules or other industry standards, including privacy and cybersecurity laws and regulations; and events beyond First Data’s or Fiserv’s control, such as acts of terrorism.

Any forward-looking statements speak only as of the date of this communication or as of the date they were made, and neither First Data nor Fiserv undertakes any obligation to update forward-looking statements. For a more detailed discussion of these factors, also see the information under the captions “Cautionary Statement Regarding Forward-Looking Statements” and “Risk Factors” in First Data’s and Fiserv’s Joint Proxy and Consent Solicitation Statement/Prospectus that forms part of the Registration Statement on Form S-4 filed by Fiserv in connection with the proposed merger and the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in First Data’s and Fiserv’s most recent reports on Form 10-K for the year ended December 31, 2018, and any material updates to these factors contained in any of First Data’s and Fiserv’s subsequent and future filings.

As for the forward-looking statements that relate to future financial results and other projections, actual results will be different due to the inherent uncertainties of estimates, forecasts and projections and may be better or worse than projected and such differences could be material. Given these uncertainties, you should not place any reliance on these forward-looking statements. Annualized, pro forma, projected and estimated numbers are used for illustrative purpose only, are not forecasts and may not reflect actual results.
