Explanatory Note

This Amendment No. 4 (“Amendment No. 4”) to Schedule 13D relates to the shares of common stock, par value $0.01 per share (the “Common Stock”), of Fiserv, Inc., a Wisconsin corporation (the “Issuer”), and amends the initial statement on Schedule 13D filed by the Reporting Persons on August 7, 2019, as amended by Amendment No. 1 to Schedule 13D filed on September 9, 2019, Amendment No. 2 to Schedule 13D filed on August 21, 2020 and Amendment No. 3 to Schedule 13D filed on December 14, 2020 (as amended, the “Schedule 13D”).  Except as specifically provided herein, this Amendment No. 4 does not modify any of the information previously reported in the Schedule 13D.  Capitalized terms used but not defined in this Amendment No. 4 shall have the same meanings herein as are ascribed to such terms in the Initial Statement.

This Amendment No. 4 is being filed by:

Item 2 of the Schedule 13D is hereby amended and supplemented as follows:

The information set forth in amended and restated Annex A hereto is incorporated by reference in this amended Item 2.

Item 2(b) of the Schedule 13D is hereby amended and restated as follows:

c/o Kohlberg Kravis Roberts & Co. L.P.

30 Hudson Yards

New York, New York 10001

The address of the principal business office of Mr. Roberts is:

c/o Kohlberg Kravis Roberts & Co. L.P.

2800 Sand Hill Road, Suite 200

Menlo Park, CA 94025

Item 4 of the Schedule 13D is hereby amended and supplemented as follows:

On April 29, 2021, New Omaha Holdings L.P., as selling stockholder, and the Issuer entered into an underwriting agreement (the “Underwriting Agreement”) with Goldman Sachs & Co. LLC and J.P. Morgan Securities LLC as underwriters (the “Underwriters”), providing for the offer and sale of 20,000,000 shares of Common Stock by New Omaha Holdings L.P. (the “April 2021 Offering”), and purchase by the Underwriters of the shares of Common Stock at a price of $117.70 per share of Common Stock. Pursuant to the Underwriting Agreement, New Omaha Holdings L.P. also granted to the Underwriters a 30-day option to purchase up to an additional 3,000,000 shares of Common Stock.  The April 2021 Offering, including the exercise of the Underwriters’ option to purchase the full amount of the 3,000,000 additional shares, closed on May 3, 2021.  The April 2021 Offering was made pursuant to the Issuer’s shelf registration statement on Form S-3 (File No. 333-227436), as supplemented by a prospectus supplement dated April 29, 2021 (the “April 2021 Prospectus Supplement”). As part of the April 2021 Offering, the Issuer repurchased from the Underwriters 5,000,000 shares of the Common Stock that were subject to the April 2021 Offering at a price per share equal to the price per share to be paid by the Underwriters to New Omaha Holdings L.P. in the April 2021 Offering (the “April 2021 Share Repurchase”).

Pursuant to the Underwriting Agreement, New Omaha Holdings L.P. has entered into a lock-up agreement (the “Lock-Up Agreement”) with the Underwriters pursuant to which it has agreed with the Underwriters, subject to customary exceptions, not to offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock during the period from April 29, 2021 continuing through the date 60 days thereafter, except with the prior written consent of the Underwriters. The foregoing description of the Lock-Up Agreement set forth in this Item 4 does not purport to be complete and is qualified in its entirety by reference to the full text of the Lock-Up Agreement, which has been filed as Exhibit J hereto and is incorporated herein by reference.

Items 5(a), (b) and (c) of the Schedule 13D are hereby amended and restated as follows:

The information set forth in Item 2 and Annex A of this Schedule 13D and the cover pages of this Schedule 13D is hereby incorporated by reference into this Item 5.

(a) and (b). The Reporting Persons may be deemed to beneficially own 62,300,667  shares of Common Stock, which represents approximately 9.4% of the outstanding shares of the Issuer’s Common Stock.

The percentage of beneficial ownership in this Schedule 13D is based on 666,769,382 shares of Common Stock outstanding as of April 23, 2021, as set forth in the April 2021 Prospectus Supplement, minus the 5,000,000 shares of Common Stock repurchased by the Issuer in the April 2021 Share Repurchase.

Each of New Omaha Holdings LLC (as the general partner of New Omaha Holdings L.P.), KKR 2006 Fund L.P. (as the sole member of New Omaha Holdings LLC), KKR Associates 2006 L.P. (as the general partner of KKR 2006 Fund L.P.), KKR 2006 GP LLC (as the general partner of KKR Associates 2006 L.P.), KKR Group Partnership L.P. (as the designated member of KKR 2006 GP LLC), KKR Group Holdings Corp. (as the general partner of KKR Group Partnership L.P.), KKR & Co. Inc. (as the sole shareholder of KKR Group Holdings Corp.), KKR Management LLP (as the Series I preferred stockholder of KKR & Co. Inc.), and Messrs. Kravis and Roberts (as the founding partners of KKR Management LLP) may be deemed to be the beneficial owner of the securities beneficially owned directly by New Omaha Holdings L.P., in each case, as described more fully in this Schedule 13D.

The filing of this Schedule 13D shall not be construed as an admission that any of the above-listed entities or individuals is the beneficial owner of any securities covered by this Schedule 13D.

To the best knowledge of the Reporting Persons, none of the individuals named in Item 2 beneficially owns any shares of Common Stock except as described in the Schedule 13D.

(c) Except as otherwise described in Item 4 of this Schedule 13D, none of the Reporting Persons, or, to the best knowledge of the Reporting Persons, any other individual named in Item 2 has engaged in any transaction in any shares of Common Stock during the past 60 days.

Item 6 of the Schedule 13D is hereby amended and supplemented as follows:

The information set forth in Items 3, 4 and 5 of the Schedule 13D is hereby incorporated by reference into this Item 6.

The disclosure under caption “Loan Facility” in Item 6 of the Schedule 13D is hereby amended and supplemented as follows:

As previously disclosed, on September 9, 2019, New Omaha Holdings L.P. (“New Omaha”) entered into a Loan Agreement (the “Loan Agreement”) with Citibank, N.A., as administrative agent and lender, and the lenders party thereto from time to time (each, a “Lender”).  Following the closing of the April 2021 Offering, New Omaha repaid a portion of the outstanding amounts under the Loan Agreement in an aggregate amount of $832 million, which includes outstanding interest accrued and payable on the principal amount being repaid.

Item 7 of the Schedule 13D is hereby amended by adding the following exhibit:

Non-Employee Director Deferred Compensation Plan, pursuant to which, following cessation of Mr. Nuttall’s service to the Issuer, each notional unit will be settled in shares of Common Stock on a one-for-one basis, and (ii) awarded 1,934 restricted stock units on May 14, 2020, each representing a contingent right to receive one share of Common Stock, which vest on the earlier of the first anniversary of the grant date or immediately prior to the first annual meeting of shareholders after the grant date.
