UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The following unaudited pro forma condensed consolidated financial statements are based upon and should be read in conjunction with historical consolidated financial statements and related notes of Pinnacle Entertainment, Inc. (“Pinnacle” or the “Company”).

The unaudited pro forma condensed consolidated balance sheet of Pinnacle as of September 30, 2006 and statements of operations for the nine months ended September 30, 2006 and for the year ended December 31, 2005, give effect to the disposition of certain Pinnacle assets held for sale as a result of discontinued operations of the Casino Magic Biloxi site and certain related assets as if the sale occurred, for balance sheet purposes, on September 30, 2006 and, for statements of operations purposes, on January 1, 2005.

In May 2006, Pinnacle executed an agreement to sell its Casino Magic Biloxi site and certain related assets in Biloxi, Mississippi. In accordance with the Statement of Financial Accounting Standard No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (“SFAS No. 144”), such assets were classified as “held for sale,” with the results of operations for Casino Magic Biloxi reflected as discontinued operations in Pinnacle’s Quarterly Report on Form 10-Q for the period ended June 30, 2006.

The results of operations of Casino Magic Biloxi were classified as a discontinued operation in the unaudited consolidated financial statements and notes thereto included in Pinnacle’s Quarterly Report on Form 10-Q as of and for the nine months ended September 30, 2006 in accordance with SFAS No. 144. As such, there are no pro forma adjustments to continuing operations necessary to reflect the Company’s sale of Casino Magic Biloxi for the nine months ended September 30, 2006.

However, as the agreement to sell Casino Magic Biloxi was not executed until May 2006, its results of operations were not classified as discontinued operations in the audited historical consolidated financial statements and notes thereto included in Pinnacle’s Annual Report on Form 10-K for the year ended December 31, 2005. As such, pro forma adjustments to continuing operations for the year ended December 31, 2005 are required to reflect the sale of Casino Magic Biloxi.

The unaudited pro forma condensed consolidated financial statements have been prepared based upon currently available information, estimates and assumptions that are deemed appropriate by Pinnacle’s management. The unaudited pro forma condensed consolidated financial statements are not necessarily indicative of the results that would have been reported had such transaction actually occurred on the dates specified, nor are they indicative of our future results of operations or financial condition. The unaudited pro forma condensed consolidated financial statements are based on and should be read in conjunction with, and are qualified in its entirety by, the historical consolidated financial statements and notes thereto of Pinnacle.

The unaudited pro forma condensed consolidated financial statements of Pinnacle are prepared in accordance with Article 11 of Regulation S-X.
