The Original Co-operation Agreement contained certain intention statements by Worldpay with respect to future equity awards and share bonuses. The UK Panel on Takeovers and Mergers (the “Panel”) has requested that such statements be removed to align with guidelines issued by the Panel.

A copy of the A&R Co-operation Agreement is attached hereto as Exhibit 2.1 and is incorporated herein by reference.

Cautionary Statement Regarding Forward-Looking Statements

This current report 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 current report are forward-looking statements including any statements regarding guidance and statements of a general economic or industry specific nature. Forward-looking statements give Vantiv’s current expectations and projections relating to Vantiv’s 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,” “will,” “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 current report are based on assumptions that Vantiv has made in light of its industry experience and its perceptions of historical trends, current conditions, expected future developments and other factors Vantiv believes 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 Vantiv’s control) and assumptions. Although Vantiv believes that these forward-looking statements are based on reasonable assumptions, you should be aware that many factors could affect Vantiv’s 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 Vantiv’s filings with the U.S. Securities and Exchange Commission (the “SEC”) and include, but are not limited to: (i) Vantiv’s ability to adapt to developments and change in Vantiv’s industry; (ii) competition; (iii) unauthorized disclosure of data or security breaches; (iv) systems failures or interruptions; (v) Vantiv’s ability to expand its market share or enter new markets; (vi) Vantiv’s ability to identify and complete acquisitions, joint ventures and partnerships; (vii) failure to comply with applicable requirements of Visa, MasterCard or other payment networks or changes in those requirements; (viii) Vantiv’s ability to pass along fee increases; (ix) termination of sponsorship or clearing services; (x) loss of clients or referral partners; (xi) reductions in overall consumer, business and government spending; (xii) fraud by merchants or others; (xiii) a decline in the use of credit, debit or prepaid cards; (xiv) consolidation in the banking and retail industries; (xv) the effects of governmental regulation or changes in laws; (xvi) outcomes of future litigation or investigations; (xvii) uncertainties as to the timing of the Business Combination; (xviii) uncertainties as to whether the Business Combination will be completed; (xix) the possibility that stockholders or other third parties will file lawsuits challenging the Business Combination; (xx) potential operating costs, customer loss and business disruption occurring prior to completion of the Business Combination or if the Business Combination is not completed; (xxi) the effect of the announcement of the Business Combination on Vantiv’s business relationships, operating results and business generally; (xxii) the failure to satisfy conditions to completion of the Business Combination, including the receipt of all required regulatory approvals; and (xxiii) difficulty in retaining certain key employees as a result of the Business Combination. Should one or more of these risks or uncertainties materialize, or should any of these assumptions prove incorrect, Vantiv’s actual results may vary in material respects from those projected in these forward-looking statements. More information on potential factors that could affect Vantiv’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 Vantiv’s periodic reports filed with the SEC, including Vantiv’s most recently filed Annual Report on Form 10-K and its subsequent filings with the SEC.

Any forward-looking statement made by Vantiv in this current report speaks only as of the date of this current report. Factors or events that could cause Vantiv’s actual results to differ may emerge from time to time, and it is not possible for Vantiv to predict all of them. Vantiv undertakes 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.

Additional Information

This current report may be deemed to be solicitation material in respect of the Business Combination, including the issuance of shares of Vantiv Stock in respect of the Business Combination. In connection with the foregoing proposed issuance of Vantiv Stock, Vantiv expects to file a proxy statement on Schedule 14A with the SEC. To the extent Vantiv effects the Business Combination as a Scheme of Arrangement under United Kingdom law, the issuance of Vantiv Stock in the Business Combination would not be expected to require registration under the Securities Act, pursuant to an exemption provided by Section 3(a)(10) under the Securities Act. In the event that Vantiv determines to conduct the Business Combination pursuant to an offer or otherwise in a manner that is not exempt from the registration requirements of the Securities Act, it will file a registration statement with the SEC containing a prospectus with respect to Vantiv Stock that would be issued in the Business Combination. INVESTORS AND STOCKHOLDERS ARE URGED TO READ THE PROXY STATEMENT AND OTHER RELEVANT DOCUMENTS FILED OR TO BE FILED WITH THE SEC CAREFULLY WHEN THEY BECOME AVAILABLE BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT VANTIV, THE BUSINESS COMBINATION AND RELATED MATTERS. Investors and stockholders will be able to obtain free copies of the proxy statement and other documents filed by Vantiv with the SEC at the SEC’s website at http://www.sec.gov. In addition, investors and stockholders will be able to obtain free copies of the proxy statement and other documents filed by Vantiv with the SEC at http://investors.vantiv.com/.

Participants in the Solicitation

Vantiv and its directors, officers and employees may be considered participants in the solicitation of proxies from Vantiv’s stockholders in respect of the Business Combination. Information regarding the persons who may, under the rules of the SEC, be deemed participants in the solicitation of Vantiv’s stockholders in connection with the Business Combination, including names, affiliations and a description of their direct or indirect interests, by security holdings or otherwise, will be set forth in the proxy statement and other relevant materials to be filed with the SEC. Information concerning the interests of Vantiv’s participants in the solicitation, which may, in some cases, be different than those of Vantiv’s stockholders generally, is set forth in the materials filed by Vantiv with the SEC, including in the proxy statement for Vantiv’s 2017 Annual Meeting of Stockholders, which was filed with the SEC on March 15, 2017, as supplemented by other Vantiv filings with the SEC, and will be set forth in the proxy statement relating to the Business Combination when it becomes available.

Disclosure Requirements of the Code

Under Rule 8.3(a) of the Code, any person who is interested in one per cent. or more of any class of relevant securities of an offeree company or of any securities exchange offeror (being any offeror other than an offeror in respect of which it has been announced that its offer is, or is likely to be, solely in cash) must make an Opening Position Disclosure following the commencement of the Offer Period and, if later, following the announcement in which any securities exchange offeror is first identified.

An Opening Position Disclosure must contain details of the person’s interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s). An Opening Position Disclosure by a person to whom Rule 8.3(a) applies must be made by no later than 3.30 p.m. (London time) on the 10th Business Day (as defined in the Code) following the commencement of the Offer Period and, if appropriate, by no later than 3.30 p.m. (London time) on the 10th Business Day (as defined in the Code) following the announcement in which any securities exchange offeror is first identified. Relevant persons who deal in the relevant securities of the offeree company or of a securities exchange offeror prior to the deadline for making an Opening Position Disclosure must instead make a Dealing Disclosure.

Under Rule 8.3(b) of the Code, any person who is, or becomes, interested in one per cent. or more of any class of relevant securities of the offeree company or of any securities exchange offeror must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any securities exchange offeror. A Dealing Disclosure must contain details of the dealing concerned and of the person’s interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror, save to the extent that these details have previously been disclosed under Rule 8. A Dealing Disclosure by a person to whom Rule 8.3(b) applies must be made by no later than 3.30 p.m. (London time) on the Business Day (as defined in the Code) following the date of the relevant dealing.

If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire or control an interest in relevant securities of an offeree company or a securities exchange offeror, they will be deemed to be a single person for the purpose of Rule 8.3.

Opening Position Disclosures must also be made by the offeree company and by any offeror and Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons acting in concert with any of them (see Rules 8.1, 8.2 and 8.4).

If you are in any doubt as to whether you are required to make an Opening Position Disclosure or a Dealing Disclosure, you should contact the Panel’s Market Surveillance Unit on +44 (0)20 7638 0129.
