As previously reported on February 14, 2017, Integra LifeSciences Holdings Corporation, a Delaware corporation (the “Company” or “Integra”), entered into a binding offer letter (the “Offer Letter”) with DePuy Synthes, Inc., a Delaware corporation (“DePuy Synthes”) and wholly-owned subsidiary of Johnson & Johnson, pursuant to which the Company made a binding offer (the “Offer”) to acquire certain assets, and assume certain liabilities, of Johnson & Johnson’s Codman neurosurgery business (the “Transaction”). The assets and liabilities subject to the proposed Transaction relate to the research, development, manufacture, marketing, distribution and sale of certain products used in connection with neurosurgery procedures (the “Business”). The purchase price for the Transaction is $1.045 billion, subject to adjustments set forth in the Purchase Agreement (as defined below) relating to the book value of inventory transferred to the Company at the closing of the Transaction, the book value of certain inventory retained by DePuy Synthes and the amount of certain prepaid taxes (as so adjusted, the “Purchase Price”).

Pursuant to the terms of the Offer Letter, following the conclusion of certain statutory information or consultation processes in connection with the Transaction by the employees of DePuy Synthes and its affiliates in France, Switzerland, and Germany, on May 11, 2017, DePuy Synthes accepted the Company’s offer and countersigned the Asset Purchase Agreement (the “Purchase Agreement”) with respect to the Transaction, previously executed by the Company. Completion of the Transaction remains subject to the satisfaction or waiver of customary closing conditions, including, among other things, (i) the expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), (ii) obtaining antitrust approvals in Spain, the United Kingdom and India, (iii) the transfer of certain product registrations required for the operation of the Business, (iv) the receipt of certain audited and unaudited financial statements of the Business, (v) the absence of a material adverse effect regarding the Business, and (vi) customary conditions regarding the accuracy of the representations and warranties and material compliance by the parties with their respective obligations under the Purchase Agreement. The parties have received antitrust clearance in India and have applied for antitrust clearance under the HSR Act and in Spain and the United Kingdom.

The foregoing summary of the Purchase Agreement and the transactions contemplated by the Purchase Agreement does not purport to be complete and is subject to, and qualified in its entirety by reference to, the full text of the Purchase Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K.

The representations, warranties and covenants of the parties contained in the Purchase Agreement have been made solely for the benefit of such parties. In addition, such representations, warranties and covenants are: (i) made only for purposes of the Purchase Agreement, (ii) qualified by confidential disclosures made by the parties to each other in connection with the Purchase Agreement, (iii) subject to materiality qualifications contained in the Purchase Agreement which may differ from what may be viewed as material by investors, (iv) made only as of the date of the Purchase Agreement or such other date as is specified in the Purchase Agreement and (v) included in the Purchase Agreement for the purpose of allocating risk between the contracting parties rather than establishing matters as facts. Accordingly, the Purchase Agreement is included with this filing only to provide investors with information regarding the terms of the Purchase Agreement, and not to provide investors with any other factual information

regarding the parties or their respective businesses. Investors should not rely on the representations, warranties or covenants, or any descriptions thereof, as characterizations of the actual state of facts or condition of the parties or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Purchase Agreement, which subsequent information may or may not be fully reflected in the parties’ public disclosures. The Purchase Agreement should not be read alone, but should instead be read in conjunction with the other information regarding the parties, the Transaction and other documents that the parties have filed and will file with the U.S. Securities and Exchange Commission.

Forward-Looking Statements

This Current Report on Form 8-K contains “forward-looking statements”, including statements regarding the proposed transaction and the ability to consummate the proposed transaction. Statements in this document may contain, in addition to historical information, certain forward-looking statements. Some of these forward-looking statements may contain words like “believe,” “may,” “could,” “would,” “might,” “possible,” “should,” “expect,” “intend,” “plan,” “anticipate,” or “continue,” the negative of these words, other terms of similar meaning or they may use future dates. Forward-looking statements in this document include without limitation statements regarding the planned completion of the Transaction, the benefits of the Transaction, including future financial and operating results, the Company’s or the Business’s plans, objectives, expectations and intentions and the expected timing of completion of the Transaction. It is important to note that the Company’s goals and expectations are not predictions of actual performance. Actual results may differ materially from the Company’s current expectations depending upon a number of factors affecting the Business and the Company’s business and risks and uncertainties associated with acquisition transactions. These factors include, among other things: successful closing of the Transaction; the risk that competing offers will be made for the Business before the Offer is accepted; the ability to obtain required regulatory approvals for the Transaction (including the approval of antitrust authorities necessary to complete the Transaction), the timing of obtaining such approvals and the risk that such approvals may result in the imposition of conditions, including with respect to divestitures, that could materially adversely affect the Company, the Business and the expected benefits of the Transaction; the risk that a condition to closing of the Transaction may not be satisfied on a timely basis or at all, the failure of the Transaction to close for any other reason and the risk liability to the Company in connection therewith; access to available financing (including financing for the acquisition) on a timely basis and on reasonable terms; the effects of disruption caused by the Transaction making it more difficult for the Company to execute its operating plan effectively or to maintain relationships with employees, vendors and other business partners; stockholder litigation in connection with the Transaction; the Company’s ability to successfully integrate the Business and other acquired businesses; global macroeconomic and political conditions; the difficulty of predicting the timing or outcome of product development efforts and regulatory agency approvals or actions, if any; physicians’ willingness to adopt and third-party payers’ willingness to provide reimbursement for the Company’s and the Business’s existing, recently launched and planned products; difficulties or delays in manufacturing; the availability and pricing of third party sourced products and materials; and other risks and uncertainties discussed in the Company’s filings with the SEC, including the “Risk Factors” sections of the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 and subsequent quarterly reports on Form 10-Q. The Company undertakes no obligation to update any forward-looking statements as a result of new information, future developments or otherwise, except as expressly required by law. All forward-looking statements in this document are qualified in their entirety by this cautionary statement.
