NEW YORK--(BUSINESS WIRE)-- Pomerantz Grossman Hufford Dahlstrom & Gross LLP is investigating claims on behalf of investors of Ceradyne, Inc. (“Ceradyne” or the “Company”) (NASDAQ: CRDN) (ISIN: US1567101050) concerning the proposed acquisition of Ceradyne by 3M in a cash transaction valued at approximately $860 million.

The investigation concerns whether the Ceradyne directors are breaching their fiduciary duties by failing to adequately shop the Company and maximize shareholder value. Under the terms of the agreement, Ceradyne shareholders would receive $35.00 in cash per share of Ceradyne common stock. However, Ceradyne stock traded above the offered price in the past year.
