NEW YORK, Aug. 26, 2013 /PRNewswire/ -- Pomerantz Grossman Hufford Dahlstrom & Gross LLP is investigating claims on behalf of investors of Onyx Pharmaceuticals, Inc. ("Onyx" or the "Company") (NASDAQ: ONXX) (ISIN: US6833991093) (CUSIP: 683399109) concerning the proposed acquisition of Onyx by Amgen, Inc. in a transaction valued at approximately $10.4 billion, or $9.7 billion net of estimated Onyx cash.

The investigation concerns whether the Onyx directors are breaching their fiduciary duties by failing to adequately shop the Company and maximize shareholder value.  Under the terms of the agreement, Onyx shareholders will receive $125.00 per share in cash for each share of Onyx common stock.  However, price to Book Value and Revenue multiples are below the averages of comparable transactions.  Moreover, the Onyx stock closed above the offered price on August 12, 2013 and at least one analyst has set a target price of $160.00 per share for Onyx common stock.

Onyx shareholders seeking more information about this acquisition are advised to contact Robert Willoughby at or 212-661-1100 or 888-476-6529, ext. 237.

The firm is also investigating actions on behalf of shareholders for the following companies:  Hilltop Community Bancorp, Inc., Dole Food Company, Inc., and Cooper Tire & Rubber Company.
