Rigrodsky & Long, P.A. Announces Investigation Of Polypore International, Inc. (NYSE: PPO) Buyout

Rigrodsky & Long, P.A. announces that it is investigating potential legal claims against the board of directors of Polypore International, Inc. (“Polypore” or the “Company”) (NYSE: PPO) regarding possible breaches of fiduciary duties and other violations of law related to the Company’s entry into an agreement to be acquired by Asahi Kasei Corporation (“Asahi Kasei”), in a transaction valued at approximately $2.2 billion.

Under the terms of the agreement, public shareholders of Polypore would receive $60.50 in cash for each share of Polypore they own.  Immediately prior to Asahi Kasei's acquisition of Polypore, 3M Company, 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 investigation concerns whether Polypore’s board of directors failed to adequately shop the Company and obtain the best possible value for Polypore’s shareholders before entering into an agreement with Asahi Kasei.  According to Yahoo! Finance, at least one analyst has issued a price target for Polypore stock at $62.00 per share.
