FIS Special Meeting (page 66)

General

The FIS special meeting will be held on July 24, 2019 at noon Eastern Time in the Peninsular Auditorium at 601 Riverside Avenue, Jacksonville, FL 32204. At the FIS special meeting, FIS shareholders will vote on:

The approval of the FIS share issuance proposal and the FIS articles amendment proposal, in each case, by the requisite vote of FIS shareholders, are required to complete the merger.

FIS Record Date

The FIS board has fixed the close of business on June 3, 2019 as the FIS record date for determination of the FIS shareholders of record entitled to vote at the FIS special meeting or any adjournment or postponement thereof. Only FIS shareholders of record as of the close of business on the FIS record date are entitled to receive notice of, and to vote at, the FIS special meeting or any adjournment or postponement thereof.

As of the close of business on the FIS record date, there were 323,837,984 shares of FIS common stock issued and outstanding and entitled to vote at the FIS special meeting, held by 9,992 shareholders of record. Each outstanding share of FIS common stock is entitled to one vote on each matter to be acted upon at the FIS special meeting.

Quorum

A quorum of outstanding shares is necessary to take certain actions at the FIS special meeting, including approval of the FIS share proposals. However, approval of the FIS adjournment proposal does not require a quorum. Shares of FIS common stock representing a majority of the votes entitled to be cast on a matter, present in person or by proxy, will constitute a quorum at the FIS special meeting. The inspector of voting appointed for the FIS special meeting will determine whether a quorum is present. The inspector of voting will treat as present for purposes of determining the presence of a quorum both (a) abstentions and (b) shares of FIS common stock for which the respective proxy card contains both a valid vote and a broker non-vote, if any such cards are received. Because it is expected that all proposals to be voted on at the FIS special meeting will be “non-routine” matters, it is unlikely that there will be any broker non-votes at the FIS special meeting.

Required Vote

Approval of the FIS share issuance proposal requires the affirmative vote of a majority of votes cast by FIS shareholders present in person or by proxy at the FIS special meeting and entitled to vote thereon, where a quorum is present.

Approval of the FIS articles amendment proposal requires the affirmative vote of a majority of the votes entitled to be cast on the amendment to the FIS articles of incorporation in person or by proxy at the FIS special meeting, i.e., the affirmative vote of the holders of a majority of the outstanding shares of FIS common stock.

Whether or not a quorum is present, approval of the FIS adjournment proposal requires the affirmative vote of a majority of votes present in person or by proxy at the FIS special meeting and entitled to vote thereon.

Abstentions are treated as shares present and entitled to vote and, under NYSE Rules, a vote cast. Abstentions will have the same effect as votes “AGAINST” the FIS share issuance proposal, the FIS articles amendment proposal and the FIS adjournment proposal. Broker non-votes, if any, will have the same effect as a vote “AGAINST” the FIS articles amendment proposal and the FIS adjournment proposal, but will have no effect on the approval of the FIS share issuance proposal.

Share Ownership of and Voting by FIS Directors and Executive Officers

As of the close of business on the FIS record date, FIS’ directors and executive officers and their affiliates were entitled to vote an aggregate of 1,023,273 shares of FIS common stock at the FIS special meeting, which represents approximately 0.32% of the issued and outstanding shares of FIS common stock entitled to vote at the FIS special meeting. In addition, as described in the section of this joint proxy statement/prospectus entitled “Certain Beneficial Owners of FIS Common Stock,” as of the close of business on the FIS record date, FIS’ directors and executive officers and their affiliates beneficially owned an aggregate of 1,023,273 shares of FIS common stock.

It is expected that FIS’ directors and executive officers will vote their shares “FOR” the FIS share issuance proposal, “FOR” the FIS articles amendment proposal and “FOR” the FIS adjournment proposal, although none of them has entered into any agreement obligating him or her to do so.

Worldpay Special Meeting (page 71)

General

The Worldpay special meeting will be held on July 24, 2019 at 12:00 p.m. Eastern Time, at The Marriott Cincinnati Northeast, 9664 S. Mason-Montgomery Road, Mason, Ohio 45040. At the Worldpay special meeting, Worldpay stockholders will vote on:

The approval of the Worldpay merger proposal by the requisite vote of Worldpay stockholders is required to complete the merger.

Worldpay Record Date

The Worldpay board has fixed the close of business on June 3, 2019 as the Worldpay record date for determination of the Worldpay stockholders of record entitled to vote at the Worldpay special meeting or any adjournment or postponement thereof. Only Worldpay stockholders of record as of the close of business on the Worldpay record date are entitled to receive notice of, and to vote at, the Worldpay special meeting or any adjournment or postponement thereof.

As of the close of business on the Worldpay record date, there were 311,276,676 shares of Worldpay Class A common stock issued and outstanding and entitled to vote at the Worldpay special meeting, held by 294 stockholders of record. Each outstanding share of Worldpay Class A common stock is entitled to one vote on each matter to be acted upon at the Worldpay special meeting.

Quorum

A majority of the issued and outstanding shares of the capital stock of Worldpay entitled to vote, present in person or by proxy, will constitute a quorum at the Worldpay special meeting. The inspector of election appointed for the Worldpay special meeting will determine whether a quorum is present at the Worldpay special meeting. The inspector of election will treat abstentions as present for purposes of determining the presence of a quorum. Broker non-votes, if any, will not be counted as present and entitled to vote for purposes of determining a quorum because it is expected that all proposals to be voted on at the Worldpay special meeting will be “non-routine” matters.

Required Vote

Approval of the Worldpay merger proposal requires the affirmative vote of the holders of a majority of the outstanding shares of Worldpay Class A common stock entitled to vote thereon at a meeting of the Worldpay stockholders at which a quorum exists. Abstentions, broker non-votes and failing to submit a vote will have the same effect as a vote “AGAINST” the Worldpay merger proposal.

Approval of the Worldpay compensation proposal requires the affirmative vote of a majority of shares present in person or by proxy at the Worldpay special meeting and entitled to vote thereon. Abstentions will have the same effect as a vote “AGAINST” the Worldpay compensation proposal. Broker non-votes and failing to submit a vote will not have any effect on the Worldpay compensation proposal.

Whether or not a quorum is present, approval of the Worldpay adjournment proposal requires the affirmative vote of a majority of shares present in person or by proxy. Abstentions will have the same effect as a vote “AGAINST” the Worldpay adjournment proposal. Broker non-votes and failing to submit a vote will not have any effect on the Worldpay adjournment proposal.

Share Ownership of and Voting by Worldpay Directors and Executive Officers

As of the close of business on the Worldpay record date, Worldpay’s directors and executive officers and their affiliates were entitled to vote an aggregate of 683,011 shares of Worldpay Class A common stock at the Worldpay special meeting, which represents approximately 0.22% of the issued and outstanding shares of Worldpay Class A common stock entitled to vote at the Worldpay special meeting. In addition, as described in the section of this joint proxy statement/prospectus entitled “Certain Beneficial Owners of Worldpay Class A Common Stock,” as of the close of business on the Worldpay record date, Worldpay’s directors and executive officers and their affiliates beneficially owned an aggregate of 2,201,490 shares of Worldpay Class A common stock.

It is expected that Worldpay’s directors and executive officers will vote their shares “FOR” the Worldpay merger proposal, “FOR” the Worldpay compensation proposal and “FOR” the Worldpay adjournment proposal, although none of them has entered into any agreement obligating him or her to do so.

The Merger and the Merger Agreement (page 80)

Under the terms and subject to the conditions of the merger agreement, Merger Sub will merge with and into Worldpay, with Worldpay as the surviving corporation in the merger and becoming a direct, wholly-owned subsidiary of FIS, and the separate corporate existence of Merger Sub will cease. Following the effective time, the Worldpay Class A common stock will be delisted from the NYSE, will be deregistered under the Exchange Act and will cease to be publicly traded.

A copy of the merger agreement is attached as Annex A to this joint proxy statement/prospectus. You are urged to read the merger agreement in its entirety because it is the legal document that governs the merger. For more information on the merger and the merger agreement, see “The Merger” and “The Merger Agreement” beginning on pages 80 and 150, respectively.

FIS and Worldpay currently expect the merger to close during the third quarter of 2019. However, as of the date of this joint proxy statement/prospectus, it is not possible to accurately estimate the closing date of the merger because the merger is subject to the satisfaction (or, to the extent permitted by applicable law, waiver) of certain conditions and requirements to FIS’ and Worldpay’s obligations to complete the merger. No assurance can be given as to when, or if, the merger will be completed.

Merger Consideration (page 151)

At the effective time, each share of Worldpay Class A common stock issued and outstanding immediately prior to the effective time (other than the excluded shares) will be converted into the right to receive, without interest and subject to any applicable withholding taxes, 0.9287 shares of FIS common stock, together with cash in lieu of fractional shares, if any, and $11.00 in cash. The shares of FIS common stock to be issued in the merger will be listed on the NYSE.

Based on the $108.88 closing price of FIS common stock on March 15, 2019, the last full trading day before the public announcement of the merger, the per share value of Worldpay Class A common stock implied by the merger consideration was $112.12 as of such date. Based on the $120.24 closing price of FIS common stock on June 4, 2019, the most recent practicable trading day prior to the date of this joint proxy statement/prospectus, the per share value of Worldpay Class A common stock implied by the merger consideration was $122.67.

The exchange ratio is fixed, which means that it will not change between now and the closing date of the merger, which we refer to as the closing date, regardless of whether the market price on the NYSE of either FIS common stock or Worldpay Class A common stock changes. Therefore, the value of the merger consideration will depend, in part, on the market price of FIS common stock at the effective time. The cash portion of the merger consideration is fixed at $11.00, without interest. The market price of FIS common stock has fluctuated since the date of the announcement of the merger agreement and will continue to fluctuate from the date of this joint proxy statement/prospectus to the date of the Worldpay special meeting, the date of the FIS special meeting, the date the merger is completed and thereafter. The market price of FIS common stock, when received by Worldpay stockholders after the merger is completed, could be greater than, less than or the same as the market price of FIS common stock on the date of this joint proxy statement/prospectus or at the date of the Worldpay special meeting. Accordingly, you should obtain current stock price quotations for FIS common stock and Worldpay Class A common stock before deciding how to vote, or whether to abstain from voting, on any of the proposals described in this joint proxy statement/prospectus. FIS common stock is traded on the NYSE under the symbol “FIS” and Worldpay Class A common stock is traded on the NYSE under the symbol “WP”.

Treatment of Fractional Shares (page 151)

No fractional shares of FIS common stock will be issued upon the conversion of shares of Worldpay Class A common stock pursuant to the merger agreement. In lieu of the issuance of any fractional shares, FIS will pay an amount in cash as further described in “The Merger Agreement—Treatment of Fractional Shares” beginning on page 151.

Treatment of Worldpay Equity Awards (page 151)

Worldpay directors, executive officers and other employees hold various types of compensatory equity awards relating to Worldpay Class A common stock. The merger agreement provides for the treatment at the effective time described below with respect to these awards.

Stock Options. Each option to acquire Worldpay Class A common stock that is outstanding immediately prior to the effective time, which we refer to as a Worldpay option, will be converted into an option to acquire a number of shares of FIS common stock (rounded down to the nearest whole share) equal to the product of (i) the number of shares of Worldpay Class A common stock subject to the option immediately prior to the effective time and (ii) the equity award exchange ratio (which is described below), which we refer to as a converted option, with an exercise price per share of FIS common stock (rounded up to the nearest whole cent) equal to (a) the per share exercise price of Worldpay Class A common stock that applies to the Worldpay option immediately prior to the effective time, divided by (b) the equity award exchange ratio. The terms and conditions of each converted option that apply following the effective time, including with respect to the vesting, forfeiture and exercisability of the converted option, will be the same as those that applied to the corresponding Worldpay option as in effect immediately prior to the effective time (including any accelerated vesting upon a qualifying termination of employment in accordance with the terms of the Worldpay option).

Time Vesting Restricted Shares. Each time vesting restricted share of Worldpay Class A common stock that is outstanding immediately prior to the effective time, which we refer to as a Worldpay restricted share, will be converted at the effective time into a restricted share award consisting of a number of shares of FIS common stock equal to the product of (i) the number of shares of Worldpay Class A common stock subject to the restricted share award immediately prior to the effective time and (ii) the equity award exchange ratio (rounded up to the nearest whole share), which we refer to as a converted restricted share. The terms and conditions of each converted restricted share that apply following the effective time, including with respect to the vesting and forfeiture of the converted restricted share, will be the same as those that applied to the corresponding Worldpay restricted share as in effect immediately prior to the effective time (including any accelerated vesting upon a qualifying termination of employment in accordance with the terms of the Worldpay restricted share).

Time Vesting Restricted Stock Units; Deferred Stock Units. Each time vesting restricted stock unit award that is outstanding immediately prior to the effective time and each deferred stock unit award relating to shares of Worldpay Class A common stock that is outstanding immediately prior to the effective time, which we refer to as a Worldpay stock unit, will be converted at the effective time into a restricted stock unit award or a deferred stock unit award, as applicable, relating to a number of shares of FIS common stock equal to the product of (i) the number of shares of Worldpay Class A common stock subject to the Worldpay stock unit immediately prior to the effective time and (ii) the equity award exchange ratio (rounded up to the nearest whole share), which we refer to as a converted stock unit. The terms and conditions of each converted stock unit that apply following the effective time, including with respect to vesting and forfeiture, will be the same as those that applied to the corresponding Worldpay stock unit as in effect immediately prior to the effective time (including any accelerated vesting upon a qualifying termination of employment or separation from service in accordance with the terms of the Worldpay stock unit).

Performance Vesting Stock Units; Performance Vesting Restricted Shares. Each performance stock unit award relating to shares of Worldpay Class A common stock that is outstanding immediately prior to the effective time and each restricted share of Worldpay Class A common stock that vests based upon attainment of performance goals and is outstanding immediately prior to the effective time, which we refer to as a Worldpay performance award, will be converted at the effective time into a time vesting award relating to a number of shares of FIS common stock equal to the product of (i) the number of shares of Worldpay Class A common stock subject to the Worldpay performance award immediately prior to the effective time, determined as described below, and (ii) the equity award exchange ratio (rounded up to the nearest whole share), which we refer to as a converted performance award. For purposes of determining the number of shares of Worldpay Class A common stock subject to each Worldpay performance award immediately prior to the effective time, the relevant performance goals will be deemed to be achieved at the following levels of performance: (1) 300% of the target level for each Worldpay performance award denominated as a “Performance Share Unit Acquisition Award,” (2) 200% of the target level for each other Worldpay performance award with a performance period beginning in 2017 or 2018, (3) 133% of the target level for each Worldpay performance award with a performance period beginning in 2019 and (4) 100% of the target level for each performance award granted prior to the date of the merger agreement with a performance period beginning in 2020, but in no event will the applicable level of achievement exceed the maximum level of performance that applies to any particular Worldpay performance award. The terms and conditions of each converted performance award that apply following the effective time will be the same as those that applied to the corresponding Worldpay performance award as in effect immediately prior to the effective time, except that the converted performance award will cliff vest based on the holder’s continued service to FIS through the scheduled completion date of the applicable performance period or such other date(s) as provided under the applicable award agreement governing the corresponding Worldpay performance award (subject to any accelerated vesting in accordance with the terms of the Worldpay performance award) without any ongoing performance vesting conditions.

Equity Award Exchange Ratio. For purposes of the conversion of Worldpay equity awards into equity awards relating to FIS common stock at the effective time as described above, the equity award exchange ratio is equal to the sum, rounded to the nearest one hundredth, of (x) the exchange ratio, plus (y) the quotient of (1) the cash consideration payable in the transaction, divided by (2) the volume-weighted average price per share of FIS common stock on the NYSE calculated for the five consecutive trading days immediately preceding (but not including) the date of closing. The equity award exchange ratio is designed to permit an adjustment which preserves, immediately following the effective time, the pre-closing intrinsic value of the Worldpay equity awards.

Worldpay Employee Stock Purchase Plan

Prior to the effective time, Worldpay is required to take all actions that may be necessary or required under the ESPP to ensure that no new offering period will be authorized or commenced after the date of the merger

agreement and to provide that, if then ongoing, the offering period that commenced on or about January 1, 2019 and the ESPP will terminate in its entirety at the effective time.

Worldpay SAYE Plans

Holders of outstanding options under the SAYE Plans will be allowed to exercise their SAYE options in connection with the merger and receive, in respect of the shares of stock they acquire, the same consideration paid to holders of shares of Worldpay Class A common stock. As of the effective time, FIS will offer holders of outstanding SAYE options the opportunity to exchange their option for an option denominated in shares of FIS common stock on the same terms and conditions as applicable prior to the effective time based on the equity award exchange ratio. With respect to SAYE options that are not exercised or exchanged as described in the preceding sentences and are exercised following the merger, FIS may take actions to provide that the shares issued with respect to any such option will be immediately transferred after exercise to FIS (or otherwise be redeemed) in exchange for a number of shares of FIS common stock and cash equal to the merger consideration holders of Worldpay Class A common stock will receive in connection with the merger. Any SAYE options that are not exchanged for options denominated in shares of FIS common stock will cease to be exercisable no later than the date that is six months following the effective time, except for SAYE Options that are or become exercisable due to a termination of employment due to death, which would be exercisable for up to one year after the termination date, as provided in the SAYE Plans.

In reaching its decision to approve the merger agreement and the transactions contemplated thereby, including the merger, and declaring it advisable that FIS enter into the merger agreement, the FIS board, as described in “The Merger—Background of the Merger” beginning on page 80, held a number of meetings, consulted with FIS’ senior management, outside legal counsel and financial advisors, and considered a number of factors it believed supported its decision to enter into the merger agreement, including, without limitation, those listed in “The Merger—Recommendation of the FIS Board; FIS’ Reasons for the Merger” beginning on page 87.

Interests of Certain Worldpay Directors and Executive Officers in the Merger (page 134)

In considering the recommendation of the Worldpay board that Worldpay stockholders vote “FOR” the Worldpay merger proposal, “FOR” the Worldpay compensation proposal and “FOR” the Worldpay adjournment proposal, Worldpay stockholders should be aware that certain executive officers and directors of Worldpay may have interests in the merger that may be different from, or in addition to, the interests of Worldpay stockholders generally. These interests include, among others, severance rights, rights to continuing indemnification and directors’ and officers’ liability insurance, accelerated vesting of certain equity awards and the right of the Worldpay CEO to be an executive of FIS and the executive vice chairman of the FIS board upon the effective time of the merger. The Worldpay board was aware of and considered these interests, among other matters, in evaluating the terms and structure, and overseeing the negotiation, of the merger, in approving the merger agreement and the transactions contemplated thereby, including the merger, and in recommending that the Worldpay stockholders adopt and approve the merger agreement.

FIS and Worldpay have agreed to use reasonable best efforts to take, or cause to be taken, all necessary actions, and to do, or cause to be done, all things necessary, proper or advisable, subject to certain limitations, to consummate and make effective the transactions contemplated by the merger agreement as promptly as practicable following the date of the merger agreement.

Any such action or challenge to the merger could result in an administrative or court order enjoining the merger or in restrictions or conditions that would have a material adverse effect on FIS after completion of the merger. Such restrictions and conditions could include requiring the divestiture or spin-off of certain businesses, assets or products, the licensing of intellectual property rights and the imposition of limitations on the ability of FIS, as a condition to completion of the merger, to operate its business as it sees fit. Neither FIS nor Worldpay can provide assurance that any such conditions, terms, obligations or restrictions will not result in the delay or abandonment of the merger.

As of the date of this joint proxy statement/prospectus, based on (i) the estimated number of shares of common stock of FIS that will be outstanding immediately prior to the completion of the merger, (ii) the estimated number of shares of Worldpay Class A common stock that will be outstanding immediately prior to the completion of the merger and (iii) the assumption that no appraisal rights are exercised by the Worldpay stockholders in connection with the merger, FIS and Worldpay estimate that the shares of FIS common stock outstanding immediately prior to the completion of the merger will constitute approximately 53%, and the shares of FIS common stock that former Worldpay stockholders are expected to receive in the merger will constitute approximately 47%, of the issued and outstanding shares of the combined company.

Debt Financing (page 140)

The merger is not subject to a financing condition.

As of March 31, 2019, FIS had total indebtedness of approximately $9.2 billion and Worldpay had total indebtedness of approximately $7.5 billion. FIS intends to repay the outstanding Worldpay debt (consisting of its

bank debt and senior notes) and pay the cash portion of the merger consideration and transaction-related expenses using an aggregate of approximately $11.1 billion in permanent financing. On May 21, 2019, FIS completed concurrent public offerings of Euro, Pound Sterling and U.S. Dollar denominated senior notes, with maturities ranging from two to 20 years, which generated gross proceeds of approximately $8.2 billion before offering expenses. Additionally, on May 29, 2019, FIS completed the establishment of a new $4.7 billion Euro-commercial paper program and entered into an amendment to its existing U.S. commercial paper program and existing revolving credit facility to increase the available borrowing capacity under each of them from $4 billion to $5.5 billion. The Euro-commercial paper program permits the issuance of commercial paper notes denominated in a range of currencies, including U.S. dollars, and having maturities of up to 183 days from the date of issue. FIS may now borrow up to $5.5 billion in the aggregate under its Euro-commercial paper program, its U.S. commercial paper program and its revolving credit facility. FIS currently intends that the remaining permanent financing required for the merger will consist of borrowing approximately $2.9 billion under a combination of its Euro-commercial paper and US commercial paper program. Finally, if desired, FIS could choose to leave the existing Worldpay senior notes outstanding, although that is not its current intention.

On March 29, 2019, FIS and certain financial institutions party to the existing revolving credit facility entered into an amendment to its existing revolving credit facility to, among other things, permit the borrowing of up to $2 billion of revolving loans on a limited conditionality basis. These revolving loans may be used to refinance certain outstanding indebtedness of Worldpay and its subsidiaries on the closing date, finance a portion of the merger consideration and pay fees and expenses related to the merger, the refinancing and the related transactions.

On April 5, 2019, FIS and certain financial institutions party to the existing revolving credit facility entered into a second amendment to the existing revolving credit facility to permit FIS to exclude indebtedness issued or incurred for the purpose of financing any acquisition that utilizes at least $1.5 billion of debt financing (including the merger) from the calculation of the maximum leverage ratio permitted thereunder prior to the consummation of such acquisition or the termination of the acquisition agreement with respect thereto; provided that such acquisition financing includes provisions requiring its repayment if the acquisition is not completed.

For information regarding the debt financing, see “The Merger—Debt Financing” beginning on page 140.

Litigation Related to the Merger (page 149)

Certain litigation is pending in connection with the merger. For more information, see “The Merger—Litigation Related to the Merger” beginning on page 149.

No Solicitation of Acquisition Proposals (page 167)

Each of FIS and Worldpay has agreed that it will not, and it will cause its subsidiaries and its subsidiaries’ executive officers and directors not to, and will direct its and its subsidiaries’ respective representatives that are not executive officers or directors not to, directly or indirectly:

Notwithstanding the foregoing, prior to the requisite approval by the FIS shareholders of the FIS share issuance proposal or prior to the requisite approval by the Worldpay stockholders of the Worldpay merger proposal, as applicable, in the event that FIS or Worldpay, as applicable, receives an unsolicited bona fide written acquisition proposal after the date of the merger agreement (which acquisition proposal did not result from a breach of the merger agreement) and the FIS board or the Worldpay board, as applicable, concludes in good faith (after receiving the advice of its outside legal counsel and its outside financial advisor) that such acquisition proposal constitutes, or would reasonably be expected to result in, a superior proposal, FIS or Worldpay, as applicable, may, and may permit its subsidiaries and its subsidiaries’ respective representatives to, furnish, or cause to be furnished, confidential or non-public information or data and participate in such negotiations or discussions to the extent that the FIS board or the Worldpay board, as applicable, concludes in good faith (after receiving the advice of its outside legal counsel and its outside financial advisor) that failure to take such actions would be inconsistent with its fiduciary duties under applicable law. Prior to providing any confidential or non-public information or data permitted to be provided pursuant to the foregoing provisions, (i) FIS or Worldpay, as applicable, are obligated to enter into a confidentiality agreement with such third party on terms no less restrictive to such person (or group of persons) than the terms of the confidentiality agreement between FIS and Worldpay, and such confidentiality agreement will not provide such person with any exclusive right to negotiate with FIS or Worldpay, as applicable, and (ii) any confidential or non-public information to be provided by FIS or Worldpay, as applicable, to such third party shall have been previously provided, or is concurrently provided, to Worldpay, in the case of FIS, or FIS, in the case of Worldpay.

For more information, including the definition of “acquisition proposal,” see “The Merger Agreement—No Solicitation of Acquisition Proposals” beginning on page 167.

Change in Board Recommendation (page 168)

Under the merger agreement, subject to certain exceptions described below, each of FIS and Worldpay has agreed to use its reasonable best efforts to obtain the requisite approval by FIS shareholders of the FIS share issuance proposal and the requisite approval by Worldpay stockholders of the Worldpay merger proposal, as applicable.

However, if the FIS board or the Worldpay board, after receiving the advice of its respective outside legal counsel and its respective outside financial advisor, determines in good faith that it would be inconsistent with its fiduciary duties under applicable law to continue to recommend the merger agreement, then the FIS board or the Worldpay board, as applicable, may take any of the following actions, which we refer to as the change in FIS recommendation or the change in Worldpay recommendation, as applicable:

Notwithstanding the foregoing, neither the FIS board nor the Worldpay board may effect a change in FIS recommendation or a change in Worldpay recommendation, as applicable, unless:

Any material amendment to an acquisition proposal will be deemed to be a new acquisition proposal, except that two business days’ prior written notice shall be given, instead of four business days as described above.

Conditions to the Completion of the Merger (page 173)

As set forth in the merger agreement, the respective obligations of each of Worldpay, FIS and Merger Sub to effect the merger are subject to the satisfaction at or prior to the effective time of the following conditions:

For more information, see “The Merger Agreement—Termination Fee” beginning on page 176.

NYSE Listing of Shares of FIS common stock (page 148)

Under the terms of the merger agreement, FIS is required to cause shares of FIS common stock to be issued in the merger to be authorized for listing on the NYSE prior to the effective time, subject to official notice of issuance. Accordingly, FIS will apply to have the shares of FIS common stock to be issued in the merger authorized for listing on the NYSE, where shares of FIS common stock are currently traded under the symbol “FIS.”

Delisting and Deregistration of Worldpay Class A Common Stock (page 148)

If the merger is completed, there will no longer be any publicly held shares of Worldpay Class A common stock. Accordingly, Worldpay Class A common stock will no longer be listed on the NYSE and will be deregistered under the Exchange Act. Under the terms of the merger agreement, Worldpay is required to cooperate with FIS and use its reasonable best efforts to enable the delisting of Worldpay Class A common stock from the NYSE and the deregistration of Worldpay Class A common stock under the Exchange Act effective as of immediately following the effective time. Worldpay, on April 10, 2019, applied for the cancellation of the listing of its Class A common stock on the standard segment of the Official List of the FCA and of trading on the Main Market of the London Stock Exchange, which we refer to as the LSE. The delisting from the LSE took effect at 8:00 am (BST) on May 20, 2019.

Comparison of the Rights of FIS Shareholders and Worldpay Stockholders (page 204)

Worldpay stockholders will have different rights once they become FIS shareholders due to differences between the organizational documents of, and governing laws applicable to, Worldpay and FIS. See “Comparison of the Rights of FIS Shareholders and Worldpay Stockholders” beginning on page 204.

Appraisal Rights (page 221)

Under Georgia law, FIS shareholders are not entitled to dissenters’ or appraisal rights in connection with the issuance of shares of FIS common stock in the merger or the FIS articles amendment proposal.

For purposes of the merger, each holder of record of Worldpay Class A common stock is entitled to appraisal rights under Delaware law in connection with the merger. Pursuant to Section 262 of the DGCL, a holder of record of Worldpay Class A common stock who does not vote for the adoption and approval of the merger agreement and who otherwise follows the procedures set forth in Section 262 of the DGCL has the right to seek appraisal of his, her or its shares of Worldpay Class A common stock, subject to certain limitations in the DGCL, and to receive payment in cash of the judicially determined fair value of his, her or its shares of Worldpay Class A common stock, exclusive of any element of value arising from the accomplishment or expectation of the merger, as determined by the Delaware Court of Chancery, together with interest, if any, to be paid upon the amount judicially determined to be the fair value of such shares of Worldpay Class A common stock. These rights are known as appraisal rights. The “fair value” of such shares of Worldpay Class A common stock as determined by the Delaware Court of Chancery may be more or less than, or the same as, the merger consideration that a holder of record of Worldpay Class A common stock is otherwise entitled to receive for the same number of shares of Worldpay Class A common stock under the terms of the merger agreement. Strict compliance with the statutory procedures in Section 262 of the DGCL is required. A holder of record of Worldpay Class A common stock who wishes to exercise appraisal rights, or preserve the ability to do so, must not vote for the Worldpay merger proposal, or deliver a signed proxy without indicating a decision on the Worldpay merger proposal. Any signed proxies returned without indicating a decision on the Worldpay merger proposal will be considered as voting “FOR” the Worldpay merger proposal.

The DGCL requirements for exercising appraisal rights are described in further detail in “Appraisal Rights” beginning on page 221, and Section 262 of the DGCL, the relevant section of the DGCL regarding appraisal rights, is reproduced and attached as Annex F to this joint proxy statement/prospectus. A holder of record of Worldpay Class A common stock intending to exercise his, her or its appraisal rights should carefully review Annex F to this joint proxy statement/prospectus in its entirety. Failure to follow precisely any of the statutory procedures set forth in Section 262 of the DGCL may result in loss of appraisal rights.

Material U.S. Federal Income Tax Consequences of the Merger (page 141)

Worldpay and FIS intend for the merger to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. Assuming that the merger is so treated, if you are a U.S. holder of Worldpay Class A common stock and you exchange all of your Worldpay Class A common stock in exchange for FIS common stock and cash in the merger, you will not recognize any gain or loss with respect to your Worldpay Class A common stock, except to the extent of any cash you may receive as part of the merger consideration and cash in lieu of a fractional share.

Worldpay has requested that Skadden render its opinion to Worldpay, dated the closing date of the merger, to the effect that, based on certain facts, representations, covenants, and assumptions, the merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. Whether such opinion can be given will depend on, among other factors, the fair market value of the FIS common stock as of the closing date of the merger.

Moreover, if such opinion is rendered, there can be no assurance that the IRS will agree with the conclusions expressed therein. The obligation of FIS and Worldpay to consummate the merger, however, is not conditioned upon the receipt of such opinion from Skadden or any other counsel, nor have the parties applied for a ruling from the IRS.

In the event that Skadden is unable to deliver an opinion that the merger will qualify as a reorganization under Section 368(a) of the Code, Worldpay and FIS will each use its reasonable best efforts to employ an alternative structure that would qualify as a reorganization within the meaning of Section 368(a) of the Code. The tax consequences of any alternative structure to holders of Worldpay Class A common stock would be the same as described below in “The Merger—Material U.S. Federal Income Tax Consequences of the Merger” if the merger qualified as a reorganization. Worldpay’s and FIS’ obligations to employ an alternative structure (A) shall not (1) without the consent of Worldpay and FIS, alter or change the amount, nature or mix of the merger consideration or (2) impose any material incremental economic costs on FIS or Worldpay or reduce the anticipated benefits to FIS or Worldpay of the merger or the other transactions contemplated by the merger agreement in any material respect and (B) shall be capable of consummation by the termination date.

If the merger fails to qualify as a reorganization within the meaning of Section 368(a) of the Code, and an alternative structure that would qualify as a reorganization within the meaning of Section 368(a) of the Code is not undertaken, a U.S. holder of Worldpay Class A common stock generally would recognize gain or loss in an amount equal to the difference between (1) the fair market value of the shares of FIS common stock and the amount of cash received in the merger by the holder (including cash received in lieu of a fractional share of FIS common stock) and (2) the holder’s basis in the Worldpay Class A common stock surrendered.

You should read “The Merger—Material U.S. Federal Income Tax Consequences of the Merger” beginning on page 141 of this joint proxy statement/prospectus for a more complete discussion of the material U.S. federal income tax consequences of the merger. The discussion of the material U.S. federal income tax consequences contained in this joint proxy statement/prospectus is intended to provide only a general discussion and is not a complete analysis or description of all potential U.S. federal income tax consequences of the merger that may vary with, or are dependent on, individual circumstances. In addition, it does not address the effects of any foreign, state or local tax laws. You should consult your tax advisor to determine the tax consequences of the merger to you.

Accounting Treatment of the Merger (page 147)

The merger will be accounted for using the acquisition method of accounting, with FIS as the acquirer of Worldpay. FIS will record assets acquired, including identifiable intangible assets, and liabilities assumed from Worldpay at their respective fair values at the effective time of the merger. Any excess of the purchase price over the fair value of such assets minus the fair value of such liabilities will be recorded as goodwill. See “The Merger—Accounting Treatment of the Merger” beginning on page 147.
