NEW YORK, Sept. 16, 2013 /PRNewswire/ -- Pomerantz Grossman Hufford Dahlstrom & Gross LLP is investigating claims on behalf of investors of Cornerstone Therapeutics, Inc. ("Cornerstone" or the "Company") (NASDAQ: CRTX) (ISIN: US21924P1030) (CUSIP: 21924P103) concerning the proposed acquisition of Cornerstone by Chiesi Farmaceutici S.p.A.

The investigation concerns whether the Cornerstone directors are breaching their fiduciary duties by failing to adequately shop the Company and maximize shareholder value.  Under the terms of the agreement, Cornerstone shareholders will receive $9.50 per share in cash for each share of Cornerstone common stock.  However, the Price to Total Assets and Revenue multiples are below the averages of comparable transactions.  In addition, at least one analyst set a target price of $14.00 per share for Cornerstone common stock, and the Cornerstone stock closed above the offered price on September 13, 2013.

Cornerstone shareholders seeking more information about this acquisition are advised to contact Robert Willoughby at rswilloughby@pomlaw.com 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.
