Item 2.02  Results of Operations and Financial Condition.

On May 9, 2006, RITA Medical Systems, Inc., a Delaware corporation (the “Company”), will announce its financial results for the first quarter ended March 31, 2006. A copy of the Company's press release announcing and commenting upon these financial results is attached as Exhibit 99.1 hereto and incorporated by reference herein.

The Company uses, and the press release contains and the related conference call will include, the non-GAAP metrics of pro-forma loss for the quarters ended March 31, 2006, December 31, 2005 and March 31, 2005, and pro-forma net loss outlook for the quarter ended June 30, 2006 and year ended December 31, 2006. The calculation of pro-forma net loss has no basis in GAAP. Additionally, the Company may use in the conference call related to the press release the non-GAAP metric earnings before interest, taxes, depreciation and amortization, (“EBITDA”), for the quarters ended March 31, 2006, December 31, 2005 and March 31, 2005. Additionally, the calculation of EBITDA in the table accompanying the press release excludes the FASB 123R stock compensation expense. Neither calculation of EBITDA has a basis in GAAP. The Company believes that all of these non-GAAP financial measure provide useful information to investors, permitting a better evaluation of the Company’s ongoing and underlying business performance, including the evaluation of its performance against its competitors in the healthcare industry. A complete reconciliation of these non-GAAP financial measures for historical periods to the most directly comparable GAAP measures is presented in the accompanying tables to the press release. Additionally, a reconciliation between the GAAP net loss and the pro-forma net loss for the Company’s outlook for the quarter ending June 30, 2006 and the year ending December 31, 2006 is included in an accompanying table to the press release.
