Item 2.02 RESULTS OF OPERATIONS AND FINANCIAL CONDITION

On April 30, 2015, Zimmer Holdings, Inc. (the “Registrant”) reported its results of operations for the quarter ended March 31, 2015. The Registrant’s earnings release is attached as Exhibit 99.1 and the information set forth therein is incorporated herein by reference and constitutes a part of this report.

The earnings release attached as Exhibit 99.1 includes two types of non-GAAP financial measures that differ from financial measures calculated in accordance with U.S. generally accepted accounting principles (“GAAP”). These non-GAAP financial measures may not be comparable to similar measures reported by other companies and should be considered in addition to, and not as a substitute for, or superior to, other measures prepared in accordance with GAAP. The first type of non-GAAP financial measure included in the press release consists of sales information reported on a constant currency basis which has been calculated by translating actual current and prior-period sales at the same predetermined exchange rate. The translated results are then used to determine year-over-year percentage increases or decreases that exclude the effect of changes in foreign currency exchange rates.

The second type of non-GAAP financial measure included in the press release consists of operating performance measures that have been adjusted to exclude certain items. The earnings release presents adjusted net earnings and adjusted diluted EPS to exclude the effects of inventory step-up and other inventory and manufacturing related charges, special items, intangible asset amortization, financing and other expenses related to the pending Biomet merger and certain tax adjustments. Included in special items are acquisition and integration costs and asset impairment charges related to prior and pending acquisitions, as well as employee termination benefits, consulting and professional fees, certain litigation matters, dedicated personnel expenses, certain contract terminations and asset impairment charges connected with global restructuring and operational excellence initiatives.

Management uses this non-GAAP information internally to evaluate the performance of the business and believes that it provides useful information to investors by offering the ability to make more meaningful period-to-period comparisons of the Registrant’s on-going operating results, the ability to better identify operating trends that may otherwise be masked or distorted by these types of items and to perform related trend analysis, and a higher degree of transparency of certain items. In addition, certain of these measures are used as performance metrics in the Registrant’s incentive compensation programs.

Reconciliations of these non-GAAP measures to the most directly comparable GAAP measure are included in the press release.

The Registrant is furnishing the information contained in this report, including the Exhibit, pursuant to Item 2.02 of Form 8-K promulgated by the Securities and Exchange Commission (the “SEC”). This information shall not be deemed to be “filed” with the SEC or incorporated by reference into any other filing with the SEC. By filing this report on Form 8-K and furnishing this information, the Registrant makes no admission as to the materiality of any information in this report, including the Exhibit.
