Forward-Looking Statements

This release contains forward-looking statements that are subject to risks and uncertainties. All statements other than statements of historical fact or relating to present facts or current conditions included in this release are forward-looking statements including any statements regarding guidance and statements of a general economic or industry specific nature. Forward-looking statements give our current expectations and projections relating to our financial condition, results of operations, guidance, plans, objectives, future performance and business. You can identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. These statements may include words such as “anticipate,” “estimate,” “expect,” “project,” “plan,” “intend,” “believe,” “may,” “should,” “can have,” “likely” and other words and terms of similar meaning in connection with any discussion of the timing or nature of future operating or financial performance or other events.

The forward-looking statements contained in this release are based on assumptions that we have made in light of our industry experience and our perceptions of historical trends, current conditions, expected future developments and other factors we believe are appropriate under the circumstances. As you review and consider information presented herein, you should understand that these statements are not guarantees of future performance or results. They depend upon future events and are subject to risks, uncertainties (many of which are beyond our control) and assumptions. Although we believe that these forward-looking statements are based on reasonable assumptions, you should be aware that many factors could affect our actual future performance or results and cause them to differ materially from those anticipated in the forward-looking statements. Certain of these factors and other risks are discussed in the company’s filings with the U.S. Securities and Exchange Commission (the “SEC”) and include, but are not limited to: (i) our ability to adapt to developments and change in our industry; (ii) competition; (iii) unauthorized disclosure of data or security breaches; (iv) systems failures or interruptions; (v) our ability to expand our market share or enter new markets; (vi) our ability to successfully integrate the businesses of our predecessor companies; (vii) our ability to identify and complete acquisitions, joint ventures and partnerships; (viii) failure to comply with applicable requirements of Visa, MasterCard or other payment networks or changes in those requirements; (ix) our ability to pass along fee increases; (x) termination of sponsorship or clearing services; (xi) loss of clients or referral partners; (xii) reductions in overall consumer, business and government spending; (xiii) fraud by merchants or others; (xiv) a decline in the use of credit, debit or prepaid cards; (xv) consolidation in the banking and retail industries; (xvi) changes in foreign currency exchange rates; (xvii) the effects of governmental regulation or changes in laws; (xviii) geopolitical, regulatory, tax and business risks associated with our international operations; and (xix) outcomes of future litigation or investigations and our dual-listings with the NYSE and LSE. Should one or more of these risks or uncertainties materialize, or should any of these assumptions prove incorrect, our actual results may vary in material respects from those projected in these forward-looking statements. More information on potential factors that could affect the company’s financial results and performance is included from time to time in the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of the company’s periodic reports filed with the SEC, including the company’s most recently filed Annual Report on Form 10-K and its subsequent filings with the SEC.

Any forward-looking statement made by us in this release speaks only as of the date of this release. Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them. We undertake no obligation to publicly update any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law.

PRELIMINARY ADJUSTED COMBINED SUPPLEMENTAL INFORMATION

We are providing this preliminary supplemental non-GAAP (Generally Accepted Accounting Principles) information to illustrate what the combined Vantiv, Inc./Worldpay Group plc (Company renamed Worldpay, Inc.) would have been had the transactions been effective at the beginning of 2016 with the new segment reporting structure, given the assumptions contained therein.

Management uses the preliminary adjusted combined non-GAAP supplemental information for purposes of evaluating business unit and consolidated company performance. The company therefore believes that the non-GAAP measures presented provide useful information to investors by allowing them to view the company’s businesses through the eyes of management, facilitating comparison of results across historical periods and providing a focus on the underlying ongoing operating performance of its businesses.

The company uses the preliminary adjusted combined non-GAAP supplemental information to supplement the financial information presented for Vantiv, Inc. on a GAAP historical basis. This non-GAAP supplemental information is not to be considered in isolation from or as a substitute for the related GAAP measures and should be read only in conjunction with financial information presented on a GAAP basis.

The preliminary historical adjusted combined financial information contained in the following supplemental information is for informational purposes only. These results do not necessarily reflect what the historical results of Worldpay, Inc. would have been if the acquisition of Worldpay Group plc had occurred on January 1, 2016. Nor is this information necessarily indicative of the future results of operations of Worldpay, Inc. The preparation of the preliminary adjusted combined financial information includes the use of estimates that may not have been accurate and assumptions that may not have been valid had the transactions occurred on January 1, 2016. However management believes them to be reasonable.

The preliminary historical adjusted combined financial information is not pro forma information prepared in accordance with Article 11 of SEC regulation S-X, and the preparation of information in accordance with Article 11 would result in a significantly different presentation.

The preliminary historical adjusted combined financial information constitutes forward-looking information and is subject to certain risks and uncertainties that could cause actual amounts to differ materially from those anticipated. See “Risk Factors” and “Cautionary Statements Regarding Forward Looking Information” included in our 2017 Annual Report on Form 10-K or as amended in subsequent filings.

The preliminary historical adjusted combined amounts reflect the historical combined results of Vantiv, Inc. and Worldpay Group plc., including information for the following combined company segments.

Merchant Solutions

Merchant Solutions primarily consists of Vantiv Inc.’s Direct, Independent Sales Organizations (ISOs), Merchant Bank sales channels and Worldpay Group plc’s U.S. and U.K segments.

Technology Solutions

Technology Solutions primarily consists of Vantiv, Inc.’s eCommerce, Paymetric, Integrated Payments sales channels and Worldpay Group plc’s Global eCommerce segments.

Issuer Solutions

Issuer Solutions primarily consists of Vantiv, Inc.’s Financial Institutions Services segment.
