Information in the transcript is qualified in its entirety by reference to the accompanying slides and the press release filed on May 21, 2012 as an exhibit to the Company’s Current Report on Form 8-K. Investors are urged to review the transcript and the slides, together with the press release, in their entirety.

The information in this Item 7.01 and Exhibit 99.1 attached hereto will not be deemed to be “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of such section, nor will such information or exhibit be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as may be expressly set forth by specific reference in such filing.

Forward Looking Statements

This Current Report on Form 8-K contains “forward-looking” statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are typically preceded by words such as “believes,” “expects,” “anticipates,” “intends,” “will,” “may,” “should,” or similar expressions. These forward-looking statements are subject to risks and uncertainties that may cause actual future experience and results to differ materially from those discussed in these forward-looking statements. Important factors that might cause such a difference include, but are not limited to, costs related to the Merger; DaVita’s or HCP’s inability to satisfy the conditions of the Merger; the need for outside financing to pay the cash consideration in the Merger; Davita’s inability to amend the senior secured credit facilities or obtain the other financing necessary to pay the cash consideration in the Merger; and other events and factors disclosed previously and from time to time in DaVita’s filings with the SEC, including DaVita’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2012 and, when filed with the SEC, the Registration Statement on Form S-4 (the “S-4”) to be filed by DaVita in connection with the shares of DaVita common stock to be issued in the Merger. DaVita bases its forward-looking statements on information currently available to it at the time of this release and undertakes no obligation to update or revise any forward-looking statements, whether as a result of changes in underlying factors, new information, future events or otherwise.

Additional Information and Where to Find It:

In connection with the Merger, DaVita intends to file with the SEC the S-4 to register the DaVita common stock issuable in the Merger. Investors and security holders are urged to read the S-4 and any other relevant documents to be filed with the SEC because they will contain important information about DaVita and HCP and the proposed transaction. Investors and security holders may obtain a free copy of the S-4 and other documents when filed by DaVita with the SEC at www.sec.gov or www.davita.com.
