Polypore Signs Definitive Agreements for Sale of the Company

CHARLOTTE, N.C., Feb. 23, 2015 (GLOBE NEWSWIRE) -- Polypore International, Inc. (NYSE:PPO) announces today that it has signed definitive agreements for the sale of the Company. In the merger agreement, Asahi Kasei Corporation ("Asahi Kasei,") (TSE1:3407), through a U.S. subsidiary, will purchase the Company for $60.50 per share in cash. As an integrated step in this transaction, immediately prior to Asahi Kasei's acquisition of Polypore, 3M Company ("3M,") (NYSE:MMM) will acquire the assets of Polypore's Separations Media segment for approximately $1.0 billion and Asahi Kasei will receive the cash proceeds from the asset sale. The definitive agreements require that the sale of the Company and the integrated sale of the Separations Media segment close after closing conditions for both transactions have been satisfied and that the closings of the transactions are conditioned upon one another.

The per share consideration represents an enterprise value for the Company of approximately $3.2 billion and a premium of approximately 24% over the volume weighted average share price for the twenty trading days up to and including February 20, 2015. The transactions have been approved by the Boards of Directors of Asahi Kasei, 3M, and Polypore, and are subject to certain customary regulatory and Polypore shareholder approvals.

"The combination of our Energy Storage business with Asahi Kasei and our Separations Media business with 3M are excellent strategic fits, which we believe create value for our people, customers and shareholders. When you combine our technology, process capabilities, and material science expertise with their technology, global reach and broader resources, there's a great opportunity to accelerate growth going forward," said Robert B. Toth, Polypore's President and Chief Executive Officer. "Clearly, our people have done a tremendous job in building strong businesses that are positioned to address exciting global market trends and needs over the long term, and have the potential to achieve a new level of success by playing a major role in the future growth of two leading global technology companies."

Commenting on the transaction, Toshio Asano, President & Representative Director of Asahi Kasei Corporation, said "We are very excited to be joining forces with Polypore, an esteemed player in energy storage. The Environment & Energy is an area of strategic focus for us as we expand and grow, creating new value for the future.
