BUCY Bucyrus International, Inc. (MM)

Attorney Advertising. The law firm of Wolf Haldenstein Adler Freeman & Herz LLP is investigating possible breaches of fiduciary duty by the Board of Directors of Bucyrus International, Inc. (“Bucyrus” or the “Company”) [NASDAQ:BUCY] arising out of the proposed acquisition of Bucyrus by Caterpillar, Inc. (“Caterpillar”).

On Monday, November 15, 2010, Caterpillar and Bucyrus announced that Caterpillar will acquire Bucyrus pursuant to an all cash offer. Under the terms of the agreement, Bucyrus stockholders will receive $92 in cash in exchange for each share of Bucyrus common stock they own. However, the Company may not have adequately shopped itself before entering into this transaction and, pursuant to this proposed transaction, Caterpillar may be underpaying for Bucyrus, thus unlawfully harming Bucyrus shareholders.

Wolf Haldenstein has been representing individual and institutional investors for many years, serving as lead counsel in numerous cases in U.S. federal and state courts. Please visit the Wolf Haldenstein website (http://www.whafh.com) for more information about the firm.
