Pomerantz Grossman Hufford Dahlstrom & Gross LLP is investigating claims on behalf of investors of Spartech Corporation (“Spartech” or the “Company”) (NASDAQ: SEH) (ISIN: US8472202097) concerning the proposed acquisition of Spartech by PolyOne Corporation in a cash and stock transaction valued at approximately $393 million. The investigation concerns whether the Spartech directors are breaching their fiduciary duties by failing to adequately shop the Company and maximize shareholder value. Under the terms of the agreement, Spartech shareholders would receive $2.67 in cash and 0.3167 shares of PolyOne common stock for each share of Spartech common stock, for a total of $8.00 per Spartech common share. However, the transaction includes substantial synergies that may not be fully reflected in what Spartech shareholders are receiving. Spartech shareholders seeking more information about this acquisition are advised to contact Ofer Ganot at email@example.com or 212-661-1100 or 888-476-6529, ext. 315.
