LAS VEGAS, NV, November 10, 2011 – Pinnacle Entertainment, Inc. (NYSE: PNK) announced today the signing of definitive agreements to sell its Boomtown Reno casino-resort operations and land adjacent to the facility in two separate transactions. Total proceeds from the transactions are expected to be approximately $22.2 million, with the potential for an additional $3.8 million if an option granted to the casino-resort buyer is exercised.

In the casino-resort transaction, the Company entered into a definitive agreement to sell Boomtown Casino and Hotel Reno and related operations to M1 Gaming Reno, LLC and SJP Reno Property, LLC for total cash consideration of approximately $12.9 million. In addition, the Company granted the buyers a one year option to purchase 100% of the Company’s membership interest in the current gaming licensee, PNK (Reno), LLC and additional land adjacent to Boomtown Reno for $3.8 million. This transaction is subject to regulatory approval and is expected to close by mid-2012. The Company classified the Boomtown Reno segment as a discontinued operation effective in the third quarter of 2011.

On the signing of these agreements, Anthony Sanfilippo, president and chief executive officer of Pinnacle Entertainment, commented, “We have been a very proud long-term partner in the Reno community, with our Team Members committed to providing outstanding experiences to our guests.
