On May 9, 2011, Allegheny Technologies Incorporated (“ATI”) acquired Ladish Co., Inc. (“Ladish”) pursuant to a merger in which LPAD Co. (“LPAD”), a wholly-owned subsidiary of ATI, was merged into Ladish, with Ladish as the surviving entity. Immediately following the merger of LPAD into Ladish and as a part of an integrated plan of reorganization, Ladish was merged into PADL LLC (“PADL”), a wholly-owned subsidiary of ATI, with PADL as the surviving entity. Pursuant to the merger, each outstanding share of Ladish common stock was converted into the right to receive the sum of 0.4556 of a share of ATI common stock and $24 in cash. The document below provides information to former shareholders of Ladish regarding the effect of the merger, for U.S. federal income tax purposes, on the adjusted tax basis of the Ladish common stock surrendered pursuant to the merger and ATI common stock received pursuant to the merger.
