NEW YORK--([ BUSINESS WIRE ])--Pomerantz Grossman Hufford Dahlstrom & Gross LLP is investigating claims on behalf of investors of Medicis Pharmaceutical Corporation (aMedicisa or the aCompanya) (NYSE: MRX) (ISIN: US5846903095) concerning the proposed acquisition of Medicis by Valeant Pharmaceuticals International, Inc. in a cash transaction valued at approximately $2.6 billion.

The investigation concerns whether the Medicis directors are breaching their fiduciary duties by failing to adequately shop the Company and maximize shareholder value. Under the terms of the agreement, Medicis shareholders would receive $44.00 in cash per share of Medicis common stock. However, the Price to EBITDA, Revenue and Asset multiples are below that of comparable transactions.

Medicis shareholders seeking more information about this acquisition are advised to contact Rebecca Jarmon at [ rjarmon@pomlaw.com ] or 212-661-1100 or 888-476-6529, ext. 314.
