On June 24, 2013, Polypore International, Inc. (the “Company”) announced that the U.S. Supreme Court declined to hear the Company’s petition for review of the 11th Circuit Court of Appeals’ Opinion upholding the Federal Trade Commission’s Order requiring the Company to divest its Microporous assets. With the Supreme Court’s decision not to hear the appeal, the divestiture provisions of the Order, which were stayed pending appeal, will now go into effect.

As announced in October 2012, the Company has already retained Wells Fargo Securities, LLC to assist in evaluating alternatives for these assets, which include the Microporous lead-acid battery separator facilities in Piney Flats, Tennessee, and Feistritz, Austria.

A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.
