DAK Americas Announces PSF Price Increase

Effective June 1, Charlotte-based DAK Americas LLC — a producer of polyester staple fibers (PSFs),
polyethylene terephthalate resins and terephthalic acid monomers; and a subsidiary of Mexico-based
Alfa S.A.B. de C.V. — will implement a 3-cents-per-pound price increase on all of its PSF products,
in addition to the 4-cents-per-pound price increase that became effective May 1. The company cited
the escalating demand for paraxylene, a raw material feedstock used to manufacture PSFs, in
announcing the increase.
