Cautionary Statement Regarding Forward-Looking Statements

Statements contained in this report that relate to future, not past, events are forward-looking statements under the Private Securities Litigation Reform Act of 1995. Forward-looking statements are based on current expectations of future events and often can be identified by words such as “expect,” “anticipate,” “will,” “intend,” “will,” “can,” “may,” “believe,” “could,” “continue,” “future,” other words of similar meaning or the use of future dates. Examples of forward-looking statements in this report include the global executive leadership team that is expected to lead the combined company upon completion of the proposed merger between Tornier and Wright and the departure of certain Tornier executive officers after completion of the merger. Forward-looking statements by their nature address matters that are, to different degrees, uncertain. Uncertainties and risks may cause Tornier’s actual results to be materially different than those expressed in or implied by Tornier’s forward-looking statements. For Tornier, such uncertainties and risks include, among others, risks relating to Tornier’s proposed merger with Wright, including the timing of the transaction; uncertainties as to whether Tornier shareholders and Wright shareholders will approve the transaction; the risk that competing offers will be made; the possibility that various closing conditions for the transaction may not be satisfied or waived, including that a governmental entity may prohibit, delay or refuse to grant approval for the consummation of the transaction, or the terms of such approval; the effects of disruption from the transaction making it more difficult to maintain relationships with employees, customers, vendors and other business partners; the risk that shareholder litigation in connection with the transaction may result in significant costs of defense, indemnification and liability; other business effects, including the effects of industry, economic or political conditions outside of Wright’s or Tornier’s control; the failure to realize synergies and cost-savings from the transaction or delay in realization thereof; the businesses of Wright and Tornier may not be combined successfully, or such combination may take longer, be more difficult, time-consuming or costly to accomplish than expected; operating costs and business disruption following completion of the transaction, including adverse effects on employee retention and on Wright’s and Tornier’s respective business relationships with third parties; transaction costs; actual or contingent liabilities; the adequacy of the combined company’s capital resources; and other risks and uncertainties. More detailed information on these and other factors that could affect Tornier’s actual results are described in Tornier’s filings with the U.S. Securities and Exchange Commission, including its most recent annual report on Form 10-K for the fiscal year ended December 29, 2013, subsequent quarterly reports on Form 10-Q and registration statement on Form S-4 filed in connection with its proposed merger with Wright.
