Exhibit 99.1

PRESENTATION OF FINANCIAL AND OTHER DATA

Financial Information Relating to Worldpay

The disclosure herein includes historical consolidated financial data of Worldpay as of and for the years ended December 31, 2014, 2015 and 2016, and selected consolidated financial data of Worldpay as of and for the nine months ended September 30, 2016 and 2017. The data for the years ended December 31, 2014, 2015 and 2016, was derived from Worldpay’s audited consolidated financial statements prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”). The data as of the nine months ended September 30, 2016 and 2017 was derived from Worldpay’s unaudited condensed consolidated financial statements. The operating results for the nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the full year.

Non-GAAP, non-IFRS and Pro Forma Financial Measures

The disclosure herein presents non-GAAP, non-IFRS and pro forma financial data including net revenue, EBITDA and Adjusted EBITDA. These are important financial performance measures for us, but are not financial measures as defined by GAAP or IFRS. The presentation of this financial data is not intended to be considered in isolation of or as a substitute for, or superior to, the financial data prepared and presented in accordance with GAAP. We use these non-GAAP, non-IFRS and pro forma financial performance measures for financial and operational decision making and as a means to evaluate period-to-period comparisons. We believe that they provide useful information about operating results, enhance the overall understanding of past financial performance and future prospects, and allow for greater transparency with respect to key metrics used by management in its financial and operational decision making.

In respect of Vantiv, we identify and explain the relevance of each of the non-GAAP measures referenced herein and how they are calculated under “Summary Unaudited Pro Forma Condensed Consolidated Financial Information.”

As used herein in respect of Worldpay only, (i) Adjusted EBITDA represents Worldpay’s profit for the period before tax charges (credits), share of results of joint ventures, finance costs, and depreciation and amortization, and adjusted to exclude certain separately disclosed items to remove the effects of changes Worldpay believes are not indicative of its underlying operating performance, (ii) Adjusted EBITDA margin represents Adjusted EBITDA divided by net revenue and (iii) “constant currency” refers to the rebasing of prior period results by calculating the foreign exchange translation applied to the prior period using the average foreign exchange rate for the period under review in order to eliminate the effect of fluctuations arising from foreign exchange translation in comparisons of period-on-period financial performance.

SUMMARY UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL DATA OF VANTIV

AND WORLDPAY

On August 9, 2017, pursuant to Rule 2.7 of the Takeover Code, Vantiv and Worldpay released the Acquisition Offer Announcement disclosing the terms on which Vantiv intends to make a recommended offer to acquire the issued and to be issued ordinary shares of Worldpay (the holders of such shares, the “Sellers”), both directly and indirectly through Vantiv UK, in a cash and stock transaction. Under the terms of the Acquisition Offer, Worldpay shareholders will be entitled to receive, for each Worldpay ordinary share held by such shareholders, £0.55 in cash and 0.0672 new shares of Vantiv Class A common stock. The Acquisition is to be effected by means of a court-sanctioned scheme of arrangement between Worldpay and Worldpay shareholders under the UK Companies Act. In addition to the consideration payable in connection with the Acquisition Offer, Worldpay shareholders received an interim dividend on October 23, 2017 of £0.008 per Worldpay ordinary share. Worldpay shareholders will furthermore be entitled to receive a special dividend of £0.042 per Worldpay ordinary share on the business day immediately preceding the effective date of the Acquisition (or such other time as Vantiv and Worldpay may agree).

On October 14, 2016, Vantiv, LLC entered into the Second Amended and Restated Credit Facilities Agreement governing the Senior Secured Credit Facilities. Subsequent to the announcement of and in connection with the Acquisition Offer, Vantiv, LLC has executed additional amendments to the loan agreement with various financial institutions and their affiliates, providing Vantiv, LLC with commitments to fund $1,605 million of additional five-year term A loans, $1,129 million of additional seven-year term B loans, and $600 million of additional revolving credit commitments. The proceeds of the additional commitments provided under the Third Amended and Restated Credit Facilities Agreement will be used to, among other things, provide the cash consideration for the Acquisition, refinance certain existing debt of Worldpay, pay fees and expenses in connection with the foregoing and for working capital and general corporate purposes. Upon release from escrow on the Completion Date, the proceeds from the senior unsecured notes offered in connection with the Acquisition Offer will be used to refinance certain existing debt of Worldpay and pay certain fees and expenses in connection with the Acquisition and related financing (the “Transactions”), including fees and expenses to be incurred in connection with this Offering.

The following summary unaudited pro forma condensed combined financial data gives effect to the Transactions, which includes adjustments for the following:

The following summary unaudited pro forma condensed combined financial data and related notes are based on and should be read in conjunction with (i) the historical audited consolidated financial statements of Vantiv and the related notes for the year ended December 31, 2016 and the historical unaudited consolidated financial statements of Vantiv and related notes for the nine months ended September 30, 2017 and 2016, and (ii) the historical audited consolidated financial statements of Worldpay and the related notes for the year ended December 31, 2016 and the unaudited condensed consolidated financial statements of Worldpay and the related notes for the nine months ended September 30, 2017 and 2016.

The summary unaudited pro forma condensed combined financial data for the nine months ended September 30, 2017 and 2016 and the year ended December 31, 2016 combine the historical consolidated statements of income of Vantiv and Worldpay, giving effect to the Transactions as if it had been completed on January 1, 2016. The summary unaudited pro forma condensed combined statement of financial position as of September 30, 2017 combines the historical condensed combined statements of financial position of Vantiv and Worldpay, giving effect to the Transactions as if they had been completed on September 30, 2017.

The historical consolidated financial information has been adjusted in the pro forma financial data to give effect to pro forma events that are (1) directly attributable to the Transactions, (2) factually supportable and (3) with respect to the unaudited pro forma condensed combined statements of income, expected to have a continuing effect on the combined results of Vantiv and Worldpay. The statements contained herein do not reflect the costs of any integration activities or benefits that may result from the realization of future cost savings from operating efficiencies, or any other synergies that may result from the Transactions.

The summary unaudited pro forma condensed combined financial data is being provided for illustrative purposes only and do not purport to represent what the Combined Company’s actual results of operations or financial position would have been had the Transactions been completed on the dates indicated, nor are they necessarily indicative of the Combined Company’s future results of operations or financial position for any future period.

The pro forma adjustments are based upon available information and certain assumptions as described in the accompanying notes to the unaudited pro forma condensed combined financial information which management believes are reasonable under the circumstances. Actual results may differ materially from the assumptions within the accompanying unaudited pro forma condensed combined financial information.

Under ASC 805, generally all assets acquired and liabilities assumed are recorded at their acquisition date fair value. For pro forma purposes, the fair value of Worldpay’s identifiable tangible and intangible assets acquired and liabilities assumed are based on a preliminary estimate of fair value. Any excess of the purchase price over the fair value of identified assets acquired and liabilities assumed will be recognized as goodwill. Management believes the fair values recognized for the assets acquired and liabilities assumed are based on reasonable estimates and assumptions.

The unaudited pro forma condensed consolidated financial data of the Combined Company for the twelve months ended September 30, 2017 presented in the following tables is calculated by (i) adding (x) the unaudited pro forma combined condensed consolidated financial data of the Combined Company for the nine months ended September 30, 2017 to (y) the unaudited pro forma combined condensed consolidated financial data of the Combined Company for the year ended December 31, 2016 and (ii) subtracting the unaudited pro forma combined condensed consolidated financial data of the Combined Company for the nine months ended September 30, 2016. Such financial data for the twelve months ended September 30, 2017 has not been audited, is not required by or presented in accordance with GAAP or IFRS or any other generally accepted accounting principles, has been prepared for illustrative purposes only and may not necessarily be representative of the results of the Combined Group for such prior period or any future period.
