Zimmer Holdings, Inc. today reported net sales of $737 million and diluted EPS of $0.47 reported and $0.58 adjusted* for the quarter ended June 30, 2004. The Company’s sales and diluted earnings per share results, on a reported and adjusted* basis, exceeded both the high end of the Company’s previous sales guidance of $730 million and earnings per share guidance of $0.42 reported and $0.55 adjusted*, and First Call estimates of $733 million and $0.55 adjusted*.

The Company’s reported results reflect its acquisition of Centerpulse AG on October 2, 2003, and Implex Corp., on April 23, 2004. Reported results include acquisition and integration expenses, inventory step-up and the prior year cumulative effect of a change in accounting principle for instrumentation, as applicable.

“The marketing and financial benefits of the Centerpulse acquisition continue to exceed our expectations,” said Ray Elliott, Zimmer Chairman, President and CEO. “Our earnings growth and the integration execution are a tribute to our team. We began this year with adjusted* EPS guidance of $2.04 to $2.07 and projected 2006 net synergies of $70 to $90 million. With today’s communication, we will have increased our 2004 EPS guidance by more than $0.20 from the beginning of this year and raised projected 2006 pre-tax net synergies to more than $100 million.”

On April 23, 2004, the Company completed its acquisition of Implex Corp., a privately held New Jersey company. In 2000, Zimmer entered into an exclusive, worldwide strategic alliance for commercialization of Implex’s innovative Hedrocel(R) biomaterial, which Zimmer marketed as Trabecular Metal(TM) Technology. Implex, which is now referred to as Zimmer Trabecular Metal Technology, Inc., operates as a wholly owned subsidiary of the Company. Zimmer has more than a dozen development projects involving Trabecular Metal Technology in the reconstructive, trauma and spinal product areas. Trabecular Metal Technology sales for 2005 for all product categories are expected to exceed $100 million.

“During the quarter, we continued to expand our leadership in Minimally Invasive Solutions(TM) (MIS(TM)) Procedures and Technologies with a record 125 surgeons trained in the month of June alone on Zimmer’s MIS 2-Incision(TM) Hip Procedure and the MIS QS(TM) Quad-Sparing(TM) Knee Procedure,” said Elliott. “We are particularly pleased with our U.S. hip sales growth of 21%. In our case, the message is clear: MIS leadership brings in new business. Zimmer MIS Procedures accounted for nearly 48% of our U.S. hip sales this quarter and the trend is upward. Surgeon demand for MIS surgical skills training is outstripping our capacity, with more than 600 surgeons in the U.S. alone awaiting Zimmer’s surgeon-to-surgeon visits and consultations.”

The Company is providing a comparison of sales to prior year on a combined* basis in the tables that follow, which includes sales of Centerpulse for the second quarter and the first six months of 2003.

Guidance

The Company’s second quarter sales guidance of $725 to $730 million included in the first quarter results press release, assumed a foreign exchange growth contribution of $29 million. Due to the strengthening of the U.S. dollar against most currencies throughout the second quarter, the foreign exchange contribution to sales growth was only $21 million. With an $8 million reduced contribution from foreign exchange, our reported sales of $737 million for the second quarter represented an even greater contribution from the Company’s underlying businesses.

As a result of the strong quarter and increased confidence in both short- and long-term integration synergies, the Company announced that it is increasing its previous sales and earnings guidance for the full year 2004. Several factors have been incorporated into the Company’s sales and earnings expectations. Foreign currency exchange rate fluctuations contributed 7% to the Company’s sales growth in the first quarter, but declined to a 3% contribution in the second quarter. If foreign currency exchange rates remain at June 30, 2004 levels, the Company expects the favorable foreign currency effect on the first six months’ sales growth will lessen throughout the balance of this year. Due to the weakening of the U.S. dollar throughout all of 2003, the favorable effect of foreign currency movement on sales growth will only be 2% in the third quarter and will result in a slightly negative contribution to sales growth in the fourth quarter. This diminishing contribution to sales growth from foreign currency exchange rate fluctuations is expected to be offset by a strengthening of the Company’s underlying sales growth. The $50 million of projected 2004 sales dis-synergies related to the Centerpulse integration have been materializing throughout the first six months, and as the Company nears completion of its non-U.S. distributor integration plans, are anticipated to be fully realized by the end of this year.

Full year sales for 2004 are projected to be in a range of $2,940 to $2,965 million, a net increase of approximately $15 million over the range in the Company’s previous guidance. When considering the $40 million reduced contribution to the Company’s full year sales growth resulting from the strengthening of the U.S. dollar against most foreign currencies during the second quarter, this really represents a $55 million guidance increase from the Company’s underlying businesses. Reported diluted earnings per share for 2004 are expected to be in the range of $1.86 to $1.90, reflecting estimated acquisition and integration expenses of $65 million and inventory step-up of $35 million, net of tax. Adjusted* diluted earnings per share are projected to be in a range of $2.26 to $2.30, an increase of $0.06 over previous guidance and an increase of more than $0.20 from the beginning of the year.

The Company believes First Call estimates for earnings are high in the third quarter, but low for the fourth quarter, with the net effect being an increase in guidance for the second half of the year. Third and fourth quarter sales for 2004 are expected to be in a range of $685 to $695 million and $775 to $790 million, respectively. Reported diluted earnings per share for the third quarter are expected to be in a range of $0.43 to $0.45, reflecting estimated acquisition and integration expenses of $18 million, inventory step-up of $3 million, net of tax, and $0.01 of dilution per share from the Implex acquisition, resulting in adjusted* diluted earnings per share in a range of $0.51 to $0.53, slightly below current First Call estimates. Reported diluted earnings per share for the fourth quarter are expected to be in the range of $0.56 to $0.58, reflecting estimated acquisition and integration expenses of $11 million and inventory step-up of $2 million, net of tax, and adjusted* diluted earnings per share in a range of $0.61 to $0.63, above current First Call estimates.
