Shareholder rights law firm Johnson & Weaver, LLP has launched an investigation into whether the board members of OM Group, Inc. (NYSE: OMG) breached their fiduciary duties in connection with the proposed sale of the Company to Apollo Global Management, LLC. Additional Information: OM Group operates as a technology-driven industrial company worldwide. It operates through Magnetic Technologies, Battery Technologies, and Specialty Chemicals segments. On June 1, 2015, OM Group announced it had signed a definitive merger agreement with Apollo Global. Under the terms of the agreement, Apollo Global will pay $34.00 per OM Group share in cash. The investigation concerns whether OM Group's board failed to satisfy their duties to the Company's shareholders, including whether the board adequately pursued alternatives to the acquisition and whether the board obtained the best price possible for the Company's shares of common stock. One Wall Street analyst has a target price greater than the proposed purchase price offered by Apollo Global. If you are a shareholder of OM Group and believe the proposed buyout price is too low or you're interested in learning more about the investigation or your legal rights and remedies, please contact lead analyst Jim Baker ( firstname.lastname@example.org) at 619-814-4471.
