As previously reported, on November 2, 2016, Brocade Communications Systems, Inc. (the “Company”) entered into an Agreement and Plan of Merger with Broadcom Limited (“Broadcom”), Broadcom Corporation and Bobcat Merger Sub, Inc. (the “Merger Agreement”) pursuant to which Broadcom agreed to acquire the Company. Broadcom Corporation subsequently assigned all of its rights under the Merger Agreement to LSI Corporation (“LSI”) on December 19, 2016. At a special meeting of the stockholders of the Company held on January 26, 2017, the proposed acquisition was approved by the holders of approximately 99.23% of the shares of common stock of the Company present in person or by proxy and entitled to vote thereon.

On July 17, 2017, following discussions with the Committee on Foreign Investment in the United States (“CFIUS”), the parties agreed to withdraw and re-file their joint voluntary notice to CFIUS under the Defense Production Act of 1950, as amended, to allow more time for review and discussion with CFIUS in connection with the proposed acquisition. Once CFIUS accepts the joint voluntary notice, it will commence a new 30-day review period, which may be followed by a 45-day investigation period.

Brocade and Broadcom have been and will continue to be actively engaged with CFIUS during its review of the proposed acquisition. There can be no assurances, however, that CFIUS will ultimately agree that the parties may proceed with the proposed acquisition.

Under the terms of the Merger Agreement and the previous extension reported by the Company on April 27, 2017, under certain specified conditions, if the proposed acquisition has not been completed on or before August 1, 2017 (such date, as may be extended, the “End Date”), either the Company or LSI may terminate the Merger Agreement unless the other party elects to extend the End Date. On July 17, 2017, in accordance with the Merger Agreement, the Company and LSI elected to extend the End Date to November 1, 2017. No other provisions of the Merger Agreement were otherwise amended or waived, and the Merger Agreement remains in full force and effect.

Brocade and Broadcom remain fully committed to the proposed acquisition and will continue to work diligently and cooperatively to close the proposed acquisition. The closing of the proposed acquisition remains subject to other conditions, including the receipt of antitrust regulatory approval in China. At this time, the parties have obtained antitrust regulatory approval or clearance for the proposed acquisition in the United States, the European Union and Japan, the only other jurisdictions for which antitrust regulatory approval or clearance is a closing condition. The Company presently expects the proposed acquisition to be completed during its fourth fiscal quarter ending October 28, 2017.
