Zimmer Holdings, Inc. Reports First Quarter 2015 Financial Results

(WARSAW, IN) April 30, 2015—Zimmer Holdings, Inc. (NYSE and SIX: ZMH) today reported financial results for the quarter ended March 31, 2015. The Company reported first quarter net sales of $1.13 billion, a decrease of 2.3% reported and an increase of 4.5% constant currency compared to the first quarter of 2014. Diluted earnings per share for the quarter were $1.02 reported and $1.58 adjusted, a decrease of 1.3% adjusted from the prior year period.

“In the first quarter, Zimmer achieved steady sales growth in several geographies and product categories, while continuing to meet our financial commitments and deliver expanded operating margin leverage,” said David Dvorak, President and CEO of Zimmer. “Notably, we recently received approval from the European Commission and the Japan Fair Trade Commission for our pending combination with Biomet, which we now expect to close during the month of May, 2015. This historic merger will enhance our leadership in musculoskeletal healthcare by drawing upon the talent and capabilities that have enabled the extraordinary growth and sustained success of our two companies.”

Net earnings for the first quarter were $177.1 million on a reported basis and $272.8 million on an adjusted basis, a decrease of 0.6% adjusted from the prior year period. Operating cash flow for the first quarter was $73.0 million, inclusive of a payment of $97.6 million to settle a pre-issuance hedge contract associated with the Company’s recent senior notes offering.

Also in the quarter, the Company paid $37.3 million in dividends and declared a first quarter dividend of $0.22 per share, consistent with the dividend declared for the prior year period.

Guidance

Based upon the continued strengthening of the U.S. dollar, the Company has updated its full-year 2015 standalone adjusted earnings guidance. The Company now expects adjusted diluted earnings per share on a standalone basis to be in a range of $6.30 to $6.40. This compares to prior full-year 2015 guidance of $6.50 to $6.60. Additionally, changes in currency rates are also expected to negatively impact Biomet earnings, which the Company expects to be partially offset by greater synergies from the pending merger than had previously been contemplated in the Company’s guidance. Net annual operating earnings synergies connected with the pending merger are now anticipated to

reach $350 million by year three following the closing of the transaction. This compares to prior guidance of net annual synergies of $270 million by the third year post-closing. Consequently, the Company now expects accretion from the pending merger with Biomet to contribute between $0.95 and $1.05 to adjusted diluted earnings per share in the first 12 months following the closing of the transaction. This accretion guidance was previously a range of $1.05 to $1.15.

Note on Non-GAAP Financial Measures and Updated Quarter Closing Convention

As used in this press release, the term “adjusted” refers to operating performance measures that exclude 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. The term “constant currency” refers to any financial measure that excludes the effect of changes in foreign currency exchange rates. Reconciliations of these non-GAAP measures to the most directly comparable GAAP measure are included in this press release.

5

Beginning with the three months ended March 31, 2015, the Company has changed its quarter-end closing convention for the majority of its international reporting units, which, in the case of the three months ended March 31, 2015, resulted in a change of that quarter-end close from March 25 to March 31. As a consequence, our results of operations for the three months ended March 31, 2015 include up to four more billing days for such international reporting units than were included in our results of operations for the three months ended March 31, 2014. The Company has not restated the presentation of the 2014 financial statements to conform to this change of closing convention because the impact of the change is not material to the results of operations or to the comparisons between the 2015 and 2014 periods.
