Bernstein Liebhard LLP is investigating whether the Board of Directors of OM Group, Inc. (“OM Group” or the “Company”) (NYSE: OMG) breached its fiduciary duty to its shareholders in agreeing to sell OM Group to funds managed by affiliates of Apollo Global Management, LLC.

Under the terms of the agreement, OM Group shareholders will receive $34.00 in cash for each share they own.  The investigation is focused on the potential unfairness of the price to OM Group shareholders and the process by which the OM Group Board of Directors considered and approved the transaction.
