Morgan Securities LLC (the “Underwriters”), the Underwriters agreed to purchase from KKR Biomet and KKR Biomet agreed to sell to the Underwriters 3,764,820 shares of Common Stock at a price of $115.31 per share (the “Sale”). The Sale closed on June 16, 2016.

Pursuant to the Underwriting Agreement, KKR Biomet signed a lock-up agreement (the “June 2016 Lock-Up Agreement”) pursuant to which it agreed with the Underwriters, subject to certain exceptions, not to dispose of or hedge any of its Common Stock or securities convertible into or exchangeable for shares of Common Stock for a period ending on August 12, 2016, except with the prior written consent of the Underwriters. The Underwriters may in their sole discretion and at any time without notice release some or all of the shares subject to the June 2016 Lock-Up Agreement prior to the expiration of the lock-up period.

As a result of the sale by the Sponsor Funds pursuant to the Underwriting Agreement, a “Principal Stockholder Rights Termination Event” will occur under the Zimmer Stockholders Agreement at the end of the day on June 16, 2016.  The occurrence of a Principal Stockholder Rights Termination Event will result in, among other things, the Sponsor Funds no longer having the right to designate any members of the Issuer’s board of directors (the “board”).

Under the Zimmer Stockholders Agreement, the Sponsor Funds would be obligated to cause their designated directors, currently Michael W. Michelson and Jeffrey K. Rhodes, to immediately resign upon the occurrence of a Principal Stockholder Rights Termination Event, unless otherwise consented to by a majority of the other members of the board.  In order to allow the board the opportunity to further discuss the future composition of the board, the Issuer has temporarily waived this obligation until the earlier of (a) the second business day following completion of the first regularly scheduled meeting of the board in July 2016 and (b) such other date as may be specified by the Issuer.

Item 5.Interest in Securities of the Issuer.

This Amendment amends and restates Item 5 of the Schedule 13D in its entirety as set forth below.

The information contained in rows 7, 8, 9, 10, 11 and 13 on the cover pages of this Schedule 13D and the information set forth or incorporated in Items 2, 4 and 6 is incorporated by reference in its entirety into this Item 5.

(a) and (b).  The Reporting Persons beneficially own an aggregate of 3,764,820 shares of Common Stock, which is directly held by KKR Biomet.  The shares of Common Stock beneficially owned by the Reporting Persons represent, in the aggregate, approximately 1.9% of the outstanding shares of Common Stock.  The percentage of beneficial ownership in this Schedule 13D is based on an aggregate of 199,678,785 shares of Common Stock outstanding as of June 13, 2016, as reported in the Issuer’s prospectus supplement dated June 13, 2016 (the “Prospectus”).

Each of KKR 2006 Fund, OPERF Co-Investment, KKR PEI Investments, 8 North America Investor and KKR Partners III (as the members of KKR Biomet); KKR Associates (as the general partner of KKR 2006 Fund and the manager of OPERF Co-Investment); KKR 2006 GP (as the general partner of KKR Associates); KKR PEI Associates (as the general partner of KKR PEI Investments); KKR PEI GP (as the general partner of KKR PEI Associates); KKR Associates 8 NA (as the general partner of 8 North America Investor); KKR 8 NA (as the general partner of KKR Associates 8 NA); KKR III GP (as the general partner of KKR Partners III); KKR Fund Holdings (as the designated member of KKR 2006 GP LLC, the sole shareholder of KKR PEI GP and the sole shareholder of KKR 8 NA); KKR Fund Holdings GP Limited (as a general partner of KKR Fund Holdings L.P.); KKR Group Holdings L.P. (as a general partner of KKR Fund Holdings L.P. and the sole shareholder of KKR Fund Holdings GP Limited); KKR Group Limited (as the sole general partner of KKR Group Holdings L.P.); KKR & Co. L.P. (as the sole shareholder of KKR Group Limited) and KKR Management LLC (as the sole general partner of KKR & Co. L.P.) may be deemed to have voting and dispositive power with respect to any shares of Common Stock beneficially owned by KKR Biomet. Such Reporting Persons disclaim beneficial ownership of such shares of Common Stock.

As the designated members of KKR Management LLC and the managers of KKR III GP LLC, Messrs. Kravis and Roberts may be deemed to share voting and dispositive power with respect to any shares of Common Stock beneficially owned by KKR Biomet. Messrs. Kravis and Roberts disclaim beneficial ownership of such shares of Common Stock.

None of Messrs. Fisher, Janetschek, Lin, Michelson or Sorkin beneficially owns any shares of Common Stock.

In addition, by virtue of the rights and obligations under the Zimmer Stockholders Agreement and Coordination Agreement, the other Sponsor Funds (which, following the closing of the Sale, shall cease to refer to affiliates of Goldman, Sachs & Co.), and the Reporting Persons may each be deemed to be a member of a “group” for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).  However, this filing shall not be deemed an admission that the Reporting Persons and the other Sponsor Funds constitute a “group” for purposes of Section 13(d) of the Exchange Act and the Reporting Persons expressly disclaim membership in any such group.  The other Sponsor Funds have separately made Schedule 13D filings reporting their beneficial ownership of shares of Common Stock.

Collectively, the Reporting Persons and the other Sponsor Funds and certain of their affiliates may be deemed to beneficially own at June 16, 2016 a total of 7,440,675 shares of Common Stock held in the aggregate by the Sponsor Funds (based on information in the Prospectus), or 3.7% of the total number of outstanding shares of Common Stock of the Issuer (based on an aggregate of 199,678,785 shares of Common Stock outstanding as of June 13, 2016, as reported in the Prospectus). Each Reporting Person disclaims beneficial ownership of the shares of Common Stock held by each of the other Sponsor Funds.

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

(d) To the best knowledge of the Reporting Persons, no person other than the Reporting Persons’ partners, members, affiliates or shareholders has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the securities of the Issuer reported as beneficially owned by the Reporting Persons.

24

(e) As of June 16, 2016, the Reporting Persons and any “group” for purposes of Section 13(d) of the Exchange Act of which they may have been deemed a part, ceased to be the beneficial owners of more than five percent of the outstanding shares of Common Stock.

Item 6.Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

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

The information in item 4 of this Schedule 13D is hereby incorporated by reference.

June 2016 Lock-Up Agreement

In connection with the registered underwritten offering undertaken by KKR Biomet and the other Sponsor Funds on June 13, 2016, KKR Biomet, certain other stockholders of the Issuer, the Issuer’s chief executive officer and chief financial officer, and certain directors of the Issuer agreed with the Underwriters, subject to certain exceptions, not to dispose of or hedge any of their Common Stock or securities convertible into or exchangeable for shares of Common Stock for a period ending on August 12, 2016, except with the prior written consent of the Underwriters. The Underwriters may in their sole discretion and at any time without notice release some or all of the shares subject to the June 2016 Lock-Up Agreement prior to the expiration of the lock-up period.
