DAK Americas Completes Acquisition Of Eastman’s PET, PTA Business

Charlotte-based DAK Americas LLC — a producer of polyester staple fibers (PSF), polyethylene
terephthalate (PET) resins and purified terephthalic acid (PTA) monomers, and a wholly owned
subsidiary of Mexico-based Alfa S.A.B. de C.V. — has acquired Kingsport, Tenn.-based Eastman
Chemical Co.’s PET and PTA business and the related Performance Polymers assets and technology.

The acquisition includes three integrated petrochemical plants in Columbia, S.C. — one
