NEW YORK--(Business Wire)--
American Securities LLC, a New York-based private equity firm, today announces
that it has completed its acquisition of GenTek, Inc., a Parsippany, New
Jersey-based provider of specialty inorganic chemical products and valve
actuation systems and components for automotive and heavy duty/commercial
engines. Equity was provided by American Securities Partners V, L.P., a $2.3
billion private equity partnership.

treatment products, primarily used by municipalities, (2) various grades of
sulfuric acid as well as sulfuric acid regeneration services for the refining
and chemical industries, (3) ingredients used in prescription pharmaceuticals,
nutritional supplements and veterinary health products, and (4) high purity

valve train components for a full range of gas and diesel engines. GenTek
operates over 50 manufacturing facilities and technical centers and has
approximately 1,100 employees.

In commenting on the transaction, Matthew F. LeBaron, a managing director of
American Securities, said, "We are delighted to have closed this investment and
to begin our partnership with GenTek`s management team. GenTek's specialty
chemicals business has a leading position in the markets it serves, and its
automotive valve business is well-positioned to grow. We are looking forward to
working with GenTek's management team to continue to build the business."

William E. Redmond, Jr., GenTek`s Chief Executive Officer, said, "We are pleased
to have completed this transaction with American Securities and look forward to
the next stage of GenTek`s development. We are excited to continue to grow and
