Pinnacle Entertainment Postpones August 29 Grand Opening of L'Auberge Casino & Hotel Baton Rouge

Pinnacle Entertainment, Inc.

is postponing the planned August 29 opening of its L'Auberge Casino & Hotel Baton Rouge project, the Company's $368 million casino entertainment property overlooking the Mississippi River. The final step in the formal licensing and approval process, commonly referred to as a mock cruise, has been delayed as Tropical Storm Isaac approaches the Gulf Coast. The storm with an uncertain path has diverted Louisiana State Police personnel required to issue the final regulatory approval for opening L'Auberge.
