Amgen and Micromet announce early termination of HSR waiting period for Amgen’s acquisition of Micromet

Amgen (NASDAQ: AMGN) and Micromet, Inc. (NASDAQ: MITI) today announced that the waiting period under the Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended (HSR), in connection with Amgen’s tender offer for Micromet, was terminated early on Feb. 14, 2012 by the U.S. Federal Trade Commission. The waiting period was scheduled to expire on Feb. 17, 2012.

As previously announced on Jan. 26, 2012, Amgen and Micromet entered into a Merger Agreement contemplating the acquisition of Micromet by Amgen via a tender offer to acquire all of the outstanding shares of Micromet’s common stock at a price of $11 per share in cash. The termination of the HSR waiting period satisfies one of the conditions to consummate the tender offer. Other closing conditions remain to be satisfied, including, among others, a minimum tender of at least a majority of outstanding Micromet shares on a fully diluted basis.

The tender offer will remain open for Micromet stockholders to tender their shares until 12:00 midnight, New York City time, at the end of Thursday, March 1, 2012, unless it is extended pursuant to and in accordance with the terms of the Merger Agreement. The complete Offer to Purchase dated Feb. 2, 2012 related to the tender offer has been filed with the U.S. Securities and Exchange Commission and can be viewed online at www.sec.gov.
