Pinnacle to acquire Ameristar Casinos for us$ 2.8 billion

This consideration represents a premium of 45% over the average closing price of Ameristar common stock for the 90 days ended December 20, 2012. The transaction has received the unanimous approval of both the Ameristar and Pinnacle Boards of Directors.

Pinnacle will benefit from increased operational and geographic diversity by more than doubling in size to 17 operating properties in 13 distinct geographies. The acquisition of Ameristar's properties will complement Pinnacle's existing portfolio by adding eight casino-resorts in some of the nation's best gaming markets, including: St. Charles near St. Louis, MO; Kansas City, MO; Council Bluffs, IA; Black Hawk, CO; Vicksburg, MS; East Chicago, IN; and Jackpot, NV.

The consideration represents an EBITDA multiple of 7.6x Ameristar's Adjusted EBITDA of us$ 365 million for the trailing 12-month period ended September 30, 2012, excluding synergies Pinnacle expects to achieve. The combined enterprise would have generated net revenue of us$ 2.4 billion and Combined Adjusted EBITDA of us$ 649 million (excluding us$ 40 million of synergies Pinnacle expects to achieve), over the trailing 12-month period ended September 30, 2012.

Anthony Sanfilippo, President and CEO of Pinnacle Entertainment commented, "The acquisition of Ameristar is a transformative transaction for Pinnacle that will provide us the scale and diversification to more effectively compete. The coupling of Pinnacle and Ameristar properties will create a terrific portfolio of quality assets to serve our combined guests. Over recent years, we have made tremendous progress at Pinnacle in providing a higher level of service to our guests and improving our financial performance. We are thrilled about the opportunities that will be created by combining the two companies. Both companies have developed cultures where team members are focused on providing a high quality experience to their guests and delivering outstanding financial outcomes for their shareholders. Our operating philosophy and cultures are perfectly aligned.

"We believe the transaction represents a uniquely attractive opportunity for Pinnacle and its shareholders given the significantly improved geographic and operational diversification of the combined portfolios," continued Sanfilippo. "In addition, we believe there is considerable opportunity to expand reach and generate synergies and efficiencies of scale from the increased size of the combined company, as well as an opportunity to drive property margin expansion by applying best practices garnered from both Pinnacle and Ameristar across the combined enterprise. As a result of the combination, we expect to achieve synergies and efficiencies of scale of at least us$ 40 million annually, with potentially greater realization as we move forward through the integration process. Finally, we expect the acquisition of Ameristar to be accretive to our free cash flow and earnings per share following the closing, and for it to provide increased long-term strategic and financial flexibility. We are confident this transaction will drive long-term value for Pinnacle's stakeholders."

Gordon Kanofsky, CEO of Ameristar Casinos commented, "We are excited to have reached this agreement with Pinnacle as this transaction maximizes value for our shareholders and provides them with a significant and immediate premium.  We are focused on ensuring a smooth transition and look forward to working with the Pinnacle team. The increased scale and diversification of the company will expand opportunities for our team members and provide enhancements for our guests."

The transaction is subject to customary closing conditions, approval by Ameristar's shareholders and required regulatory approvals. Pinnacle expects the transaction to close by the end of the third quarter of 2013. Pinnacle has obtained committed financing for the transaction and the transaction is not subject to a financing contingency.
