Item 2.02  Results of Operations and Financial Condition.

On November 7, 2006, RITA Medical Systems, Inc., a Delaware corporation (the “Company”), will announce its financial results for the third quarter ended September 30, 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 net loss and EBITDA for the periods ended September 30, 2006 and 2005, and pro-forma net loss outlook for the quarter and year ended December 31, 2006. The calculations of pro-forma net loss and EBITDA (earnings before interest, taxes, depreciation and amortization, and also excluding FASB 123R stock compensation expense, collectively “EBITDA”) have no basis in GAAP. The Company believes that all of these non-GAAP financial measures 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. Additionally, a reconciliation between the GAAP net loss and the pro-forma net loss for the Company’s outlook for the quarter and the year ending December 31, 2006 is included in an accompanying table to the press release.
 
The information in this Form 8-K and the exhibit attached hereto shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, (the "Exchange Act") or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, regardless of any general incorporation language in such filing.
