In addition to the financial consideration of the licensing arrangement, we are pleased that this agreement establishes the opportunity for Polypore and Sumitomo to work together to address growing market needs, which we expect to benefit both companies. As interest in coated separator solutions continues to grow, we believe that the combined strength of our intellectual property, Sumitomo’s technical expertise in coating and the exceptional performance characteristics of our separator material create an attractive solution for meeting the growth needs of existing and future customers.—Robert Toth, President and CEO of Polypore
