Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On June 6, 2016, Zimmer Biomet Holdings, Inc., a Delaware corporation (the “Company” or “Zimmer Biomet”), LDR Holding Corporation, a Delaware corporation (“LDR”), and LH Merger Sub, Inc., a Delaware corporation and an indirect wholly owned subsidiary of the Company (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”).

Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, the Company has agreed to cause Merger Sub to commence a tender offer (the “Offer”) to acquire all of the outstanding shares of common stock, par value $0.001 per share, of LDR (“LDR Shares”), at a purchase price of $37.00 per share (the “Offer Price”), net to the seller in cash, without interest, subject to any required deduction or withholding of taxes.

The obligations of the Company and Merger Sub to consummate the Offer are conditioned on, among other conditions, that at least a majority of the outstanding LDR Shares, when added to LDR Shares owned by the Company and Merger Sub (if any) (excluding LDR Shares tendered pursuant to guaranteed delivery procedures that have not yet been “received,” as such term is defined in Section 251(h) of the General Corporation Law of the State of Delaware (the “DGCL”)), are validly tendered and not properly withdrawn. In addition to this minimum tender condition, completion of the Offer is subject to the satisfaction or waiver of a number of other customary closing conditions as set forth in the Merger Agreement, including the expiration or termination of the applicable waiting period under the United States Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

Immediately following completion of the Offer, upon the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into LDR (the “Merger”), with LDR surviving the Merger as an indirect wholly owned subsidiary of the Company. The Merger Agreement provides that, if the Offer is completed, the Merger will be effected pursuant to Section 251(h) of the DGCL, which permits the completion of the Merger without a vote of the holders of LDR Shares.

At the effective time of the Merger (the “Effective Time”), any LDR Shares issued and outstanding immediately prior to the Effective Time (other than LDR Shares owned by LDR as treasury shares and LDR Shares owned by the Company, Merger Sub or any of their respective subsidiaries and LDR Shares held by stockholders who are entitled to demand and properly demand appraisal rights in accordance with Section 262 of the DGCL and who have otherwise complied in all respects with Section 262 of the DGCL) will be automatically converted into the right to receive cash in an amount equal to the Offer Price (the “Merger Consideration”), without interest, subject to any required deduction or withholding of taxes. In addition, at the Effective Time, all outstanding options, restricted stock units, performance stock units and phantom units issued by LDR pursuant to its equity plans will be cancelled and converted into the right to receive the amount of cash determined in accordance with the terms of the Merger Agreement.

The Company, Merger Sub and LDR have made customary representations and warranties in the Merger Agreement and agreed to certain customary covenants, including covenants regarding the operation of the business of LDR prior to completion of the Merger.

The LDR board of directors has resolved to recommend that holders of LDR Shares accept the Offer and tender all of their LDR Shares to Merger Sub pursuant to the Offer, and LDR has agreed not to solicit alternative transactions, subject to customary exceptions.

The Merger Agreement contains certain termination rights by the Company and LDR, including, among others, if the Offer is not consummated at or prior to midnight on October 6, 2016; provided that this date may be extended to February 6, 2017 by either party under circumstances specified in the Merger Agreement to satisfy the condition to the Offer relating to the expiration or termination of the applicable HSR waiting period. Upon termination of the Merger Agreement under specified circumstances, including a termination by LDR to enter into an agreement for an alternative transaction pursuant to a “superior proposal” or an adverse change to the LDR board of directors’ recommendation of the Offer, LDR has agreed to pay the Company a termination fee of $34.2 million, and, if the Company terminates the Merger Agreement under certain circumstances, LDR has agreed to reimburse the Company for up to $11.4 million of its expenses.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is attached hereto as Exhibit 2.1 and incorporated by reference herein. The Merger Agreement has been included as an exhibit hereto solely to provide investors and security holders with information regarding its terms. It is not intended to be a source of financial, business or operational information about the Company, LDR or their respective subsidiaries or affiliates.

The representations, warranties and covenants contained in the Merger Agreement are made only for purposes of the Merger Agreement and are made as of specific dates; are solely for the benefit of the parties; may be subject to qualifications and limitations agreed upon by the parties in connection with negotiating the terms of the Merger Agreement, including being qualified by confidential disclosures made for the purpose of allocating contractual risk between the parties rather than establishing matters as facts; and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors or security holders. Investors and security holders should not rely on the representations, warranties and covenants or any description thereof as characterizations of the actual state of facts or condition of the Company, LDR or their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in public disclosures.
