WeissLaw LLP, a national class action and shareholder rights law firm with offices in New York City and Los Angeles, is investigating possible breaches of fiduciary duty and other violations of law by the Board of Directors of Ameristar Casinos, Inc. (“Ameristar” or the “Company”) (NASDAQ GS: ASCA) arising from its agreement for Ameristar to be acquired by Pinnacle Entertainment, Inc. (“Pinnacle”) (NYSE: PNK), in a transaction valued at approximately $2.8 billion. Under the terms of the proposed transaction Ameristar shareholders will receive $26.50 in cash for each Ameristar share they own. This price is below the target price set by certain securities analysts. WeissLaw LLP is investigating whether Ameristar’s Board acted in the best interests of its public shareholders by actively shopping the Company to maximize shareholder value for Ameristar’s public shareholders, prior to entering into the proposed transaction with Pinnacle. If you own Ameristar shares and would like more information about your rights as a shareholder or additional information concerning our investigation, please contact Joshua M.
