Note on Non-GAAP Financial Measures

Wright Medical Group, Inc. (“Wright”) and Tornier N.V. (“Tornier”) use non-GAAP financial measures, including EBITDA, as adjusted. Their respective management teams believe that the presentation of these measures provides useful information to investors and that these measures may assist investors in evaluating their respective company’s operations, period over period. EBITDA is calculated by adding back to net income charges for interest, income taxes and depreciation and amortization expenses. While it is not possible to reconcile the adjusted EBITDA forecast in this communication to the nearest metric under U.S. generally accepted accounting principles (GAAP) of the combined business without unreasonable effort, the adjusted EBITDA forecast excludes non-cash stock based compensation expense and non-operating income and expense, as well as the expected impact of such items as transaction and transition costs, impacts from the sale of Wright’s OrthoRecon business and costs associated with distributor conversions and non-competes, all of which may be highly variable, difficult to predict and of a size that could have substantial impact on the combined company’s reported results of operations for a period. Investors should consider these non-GAAP measures only as a supplement to, not as a substitute for or as superior to, measures of financial performance prepared in accordance with GAAP.
