DAVITA INC. REPORTS 4th QUARTER AND YEAR ENDED 2004 RESULTS

El Segundo, California, February 8, 2005 – DaVita Inc. (NYSE: DVA), today announced results for the quarter and year ended December 31, 2004. Net income for the three months ended December 31, 2004, was $56.6 million and $0.56 per share. Net income for the year ended December 31, 2004, was $217.2 million, and $2.11 per share, excluding after-tax Medicare lab recoveries of $5.1 million.

Net income for the year ended December 31, 2004 including the lab recoveries (GAAP basis), was $222.3 million and $2.16 per share.

Financial and operating highlights include:

• Cash Flow: Cash flow for the 12 months ended December 31, 2004, was our strongest ever with operating cash flow and free cash flow of $361 million and $314 million, excluding the tax benefit from stock option exercises and the after-tax benefit of prior years’ Medicare lab recoveries. Including those items, 12-month operating cash flow was $420 million.

• Operating Income: Operating income for the three months was $105.2 million. Operating income for the year ended December 31, 2004 was $401.8 million, excluding Medicare lab recoveries of $8.3 million for prior years’ services.

• Volume: Total treatments for the fourth quarter were 1,895,952 or 23,999 treatments per day, an increase of 14.5% per day compared to the fourth quarter of last year. Total treatments for 2004 were 7,062,424 or 22,528 treatments per day, representing an increase of 10.6% per day as compared to 2003. Non-acquired treatment growth was 6.0% and 5.0% for the fourth quarter and full year 2004, respectively.

• Effective Tax Rate: The final effective annual income tax rate for 2004 was 38.6%. The fourth quarter benefited from a year-to-date reduction in the annualized effective tax rate that added $0.01 to fourth quarter earnings per share. At this time, the effective tax rate for 2005 is projected to be at a comparable level.

• Center Activity: As of December 31, 2004, we operated or provided administrative services at 658 outpatient centers serving approximately 54,000 patients. During the fourth quarter we acquired 6 centers, opened 19 de novo centers and provided administrative services to 2 additional centers. We also closed 4 centers and terminated one administrative services agreement.

Outlook

Our previous 2005 operating income guidance was for operating income to improve from 0 to 6% over the 2004 operating income performance. Our new 2005 operating income guidance is for operating income to be up 2 to 6% over 2004, exclusive of the effects of the proposed Gambro Healthcare acquisition and related debt financing, as well as the anticipated expensing of stock options in accordance with FASB No. 123R. In connection with the Gambro acquisition the Company will be assessing financing alternatives, which could include closing some or all of the financing in advance of the closing of the acquisition. At this time, we expect the Gambro acquisition together with related debt financing to be dilutive to EPS in the first year, neutral in the second year and accretive thereafter.

DaVita will be holding a conference call to discuss its fourth quarter and year ended results for 2004 on February 9, 2005, at 12:00 PM Eastern Time. The dial in number is 800-399-4406. A replay of the conference call will be available on DaVita’s official web page, www.davita.com, for the following 30 days.

This release contains forward–looking statements. Factors which could impact future results include the uncertainties associated with governmental regulations, general economic and other market conditions, acquisitions and the risk factors set forth in the Company’s SEC filings, including its Form 10-Q for the quarter ended September 30, 2004. The forward-looking statements should be considered in light of these risks and uncertainties.

These risks and uncertainties include those relating to:

• the concentration of profits generated from PPO and private indemnity patients,

• possible reductions in private and government reimbursement rates,

• changes in pharmaceutical practice patterns or reimbursement policies,

• the Company’s ability to maintain contracts with physician medical directors,

• legal compliance risks, including our continued compliance with complex government regulations and the ongoing review by the U.S. Attorney’s Office for the Eastern District of Pennsylvania, and the HHS Office of the Inspector General and the recently announced subpoena from the U.S. Attorney’s Office for the Eastern District of New York, and

• the consummation of the Gambro acquisition, terms of the related financing, and subsequent integration of the business.

This Company undertakes no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise.

4. Free cash flow, excluding Medicare lab recoveries related to prior years’ services, and tax benefit from stock option exercises:

Free cash flow represents net cash provided by operating activities less non-development capital expenditures. We believe free cash flow is a useful adjunct to cash flow from operating activities and other measurements under generally accepted accounting principles in the United States since it is a meaningful measure of our ability to fund acquisition and development activities and meet our debt service requirements. Free cash flow is not a measure of financial performance under generally accepted accounting principles in the United States and should not be considered as an alternative to cash flows from operating, investing or financing activities, as an indicator of cash flows, or as a measure of liquidity.
