Arkema To Purchase Coatex

Arkema, a France-based manufacturer
of industrial chemicals, and performance and vinyl products, has announced it will acquire Coatex,
a France-based manufacturer of specialty polymers, mostly acrylic-based, for such applications as
textiles, cosmetics, paper, paint and water treatment. Wholly owned by the Omya Group, Switzerland,
Coatex currently employs 300 associates, and has operations worldwide — including facilities in the
United States, France, the Netherlands and Korea. The company reported sales of 150 million euros
(US$204.3 million) last year.

“This first acquisition is fully part of our strategy to refocus Arkema on its strongest
product lines,” said Thierry Le Hénaff, chairman and CEO, Arkema. “It will reinforce the
integration of our portfolio, helping Arkema to become more resilient to economic cycles. This
acquisition is a unique growth opportunity in the field of high-added-value acrylic polymers.”

The purchase follows Arkema’s recent announcement that it will divest non-strategic assets
in an effort to focus on its development processes and overall transformation.
