Pinnacle Entertainment Comments on Federal Trade Commission Administrative
Complaint

LAS VEGAS, May 29, 2013 (GLOBE NEWSWIRE) -- Pinnacle Entertainment, Inc.
(NYSE:PNK) today commented on the administrative complaint issued by the
Federal Trade Commission ("FTC") regarding Pinnacle Entertainment's proposed
acquisition of Ameristar Casinos. According to the FTC's press release, the
administrative complaint alleges that the combination of the two companies
will lessen competition in the St. Louis and Lake Charles areas.

"We are disappointed by the FTC's decision to issue an administrative
complaint regarding our proposed acquisition of Ameristar Casinos," said
Anthony Sanfilippo, CEO of Pinnacle Entertainment."We continue to believe
that the merger of these two gaming-entertainment property portfolios would
not have any adverse effect on competition in any of the geographies in which
the combined company would operate, and remain excited about the compelling
benefits that the merger will provide to our guests, team members and
shareholders.We are committed to completing the transaction as expeditiously
as possible and in the time frame agreed upon with Ameristar," said
Sanfilippo.
