Former United States Securities and Exchange Commission attorney Willie Briscoe and the securities litigation firm of Powers Taylor LLP are investigating potential claims against the Board of Directors of OM Group Inc. ("OM Group") (NYSE: OMG) concerning the sale to Apollo Global Management Affiliates. Under the terms of the agreement, OM Group shareholders will only receive $34.00 in cash for each share owned, which is virtually no premium over the 52-week high and significantly lower than at least one analyst's estimated value of $37.00 per share. If you are an affected investor, and you want to learn more about the investigation or if you have information that you believe would be helpful to our investigation of the fairness of the proposed transaction, contact Willie Briscoe at The Briscoe Law Firm, PLLC via email at firstname.lastname@example.org, Patrick Powers at Powers Taylor LLP via e-mail at email@example.com or by calling toll free at (877) 728-9607.

The investigation centers on whether OM Group's Board of Directors is acting in the shareholders' best interests, whether the board considered alternatives to the acquisition, and whether the board has employed an adequate process to review and act on the proposed transaction. Notably, at least one analyst with Yahoo! Finance believes the true inherent value of the stock could be as high as $37.00.
