(WARSAW, IN) January 31, 2005 — Zimmer Holdings, Inc. (NYSE and SWX: ZMH) today reported net sales and earnings for the fourth quarter and year ended December 31, 2004. For the fourth quarter, the Company reported net sales of $801 million and diluted earnings per share of $0.81 and $0.71 adjusted*. Full year net sales were $2.98 billion and diluted earnings per share were $2.19 reported and $2.41 adjusted*. The Company’s fourth quarter sales and diluted earnings per share results adjusted* exceeded the high end of the Company’s guidance and First Call estimates of $783 million and $0.64, respectively.

The Company’s reported results reflect its acquisitions of Centerpulse AG on October 2, 2003, and Implex Corp. on April 23, 2004. Reported results include in-process R&D write-offs, acquisition and integration expenses, inventory step-up, a tax benefit from decreased deferred taxes of acquired Centerpulse operations that resulted from a reduction in the ongoing Swiss tax rate, and the prior year cumulative effect of a change in accounting principle for instrumentation, as applicable.

“Zimmer’s winning performance continues as evidenced by our strong sales, margins and cash flow,” said Ray Elliott, Zimmer Chairman, President and CEO. “During 2004, we invested heavily in the expansion of landscape-changing innovations such as Minimally Invasive Solutions™ (MIS™) Procedures and Technologies and Trabecular Metal™ Technology. We delivered more than 40 major development projects to the market. We generated more than $540 million in new product sales. The future should be equally rich with a 146 project pipeline, two-thirds of which is devoted to innovative technology and advanced platforms.”

Zimmer has continued to focus on Minimally Invasive Solutions Procedures and Technologies. During the year, the Company trained more than 1,400 surgeons; added two new Zimmer Institutes; documented potentially improved hospital profitability with almost 1,000 patients; launched a 13 city, low-cost DTC campaign capitalizing on more than 100,000 visits to the Company’s MIS “Find-a-Doc” web-based surgeon locator; and supported 17 different MIS papers. In addition, Zimmer placed more than 2,000 MIS Quad-Sparing™ Knee Replacement and Mini-Knee Replacement instrument sets in the field—by management estimates, more than the Company’s top three competitors combined.

2

“As we enter 2005, a key focus continues to be the integration of Centerpulse and Implex, including the realization of both targeted synergies and identified opportunities,” said Elliott. “The year 2004 was a great beginning—we are ahead of schedule having already accomplished more than 2,000 of the total 3,364 integration milestones and raised the estimated, sustainable cost synergies to slightly over $100 million annually from our original estimates of $70 to $90 million.”

The following tables provide a comparison of sales results for the fourth quarter and full year. Because the Centerpulse acquisition closed on October 2, 2003, Centerpulse sales were included in Zimmer’s fourth quarter 2003 results and there is no distinction made between reported and combined* in the table for the fourth quarter. The full-year comparison is on a combined* basis because Centerpulse was an independent company during the first three quarters of 2003.

Guidance
The following guidance falls within the Company’s previous expectations for the combination of Zimmer and Centerpulse to deliver a minimum of 10% sales growth in 2005, a 20% to 25% diluted earnings per share adjusted* growth in 2005, and the potential to exceed a 25% diluted earnings per share adjusted* growth in 2006. Earnings per share guidance for 2005 and 2006 excludes the impact of changes in U.S. GAAP related to accounting for equity-based compensation. Many factors are incorporated into the Company’s guidance. The factors discussed below are not intended to be an exhaustive list of the factors considered.

As a result of potential foreign currency exchange rate fluctuations throughout 2005, the negative pricing effects of the changing German reimbursement system, and the second quarter 2004 price decreases in Japan, the Company is maintaining its previous full year 2005 sales guidance to be in a range of $3,325 million and $3,345 million. This represents sales growth of approximately 12.0% over full year 2004. Considering the effects of anticipated new product introductions throughout 2005, sales growth for the last six months of 2005 should be slightly above this annual growth range, and sales for the first six months should be slightly below this range. Additionally, the first quarter of 2005 contains two fewer billing days than the same period in 2004, while the second quarter contains one additional billing day. Consequently, sales growth in the first quarter 2005 should be approximately 9.0% reported (representing 12% growth on a per billing day basis), while sales growth in the second quarter should be approximately 15.0% reported (representing 13% growth on a per billing day basis).

With the Company’s improved gross profit and operating profit margins reported in the fourth quarter of 2004, it is increasing its previous full year adjusted* earnings per share estimates for 2005 by $0.06 to a range of $2.89 to $2.91, an increase over prior year of approximately 21% adjusted*. The Company expects reported earnings per share in the first half of 2005 to be in a range of $1.32 to $1.33, and adjusted* earnings per share to be in a range of $1.40 to $1.41, with approximately $0.66 to $0.67 in the first quarter and approximately $0.74 in the second quarter.

6

The Company also expects reported earnings per share in the second half of 2005 to be in a range of $1.44 to $1.45, and adjusted* earnings per share in a range of $1.49 to $1.50.

*Note on Non-GAAP Financial Measures

As used in this press release, the term “combined” sales includes Centerpulse for the first, second and third quarters of 2003 in order to provide more meaningful year-to-year comparisons. The term “adjusted” refers to operating performance measures that exclude in-process R&D write-offs, acquisition and integration expenses, inventory step-up, a tax benefit from decreased deferred taxes of acquired Centerpulse operations that resulted from a reduction in the ongoing Swiss tax rate, and the cumulative effect of the change in accounting principle for instruments. The term “net debt” refers to short-term and long-term debt obligations minus the Company’s cash and equivalents and restricted cash. Reconciliations of non-GAAP measures to the most directly comparable GAAP measure are included in this press release.
