Enthone Becomes An Alent plc Company

West Haven, CT USA – January 2, 2013 – As a result of the December 19, 2012 demerger of Cookson Group plc its two main divisions, the Enthone and Alpha businesses, became part of the newly formed Alent plc (LSEX: ALNT), previously Cookson Performance Materials.

The management of the former Cookson Performance Materials will remain intact with Chief Executive, Steven Corbett continuing to lead this new UK publicly-listed company.

Enthone and Alpha will continue operating under their current trade names, and relationships and obligations with customers and suppliers will remain unchanged. The company will stay strongly focused on supporting business growth and success; nothing will change regarding the way in which business is conducted.

This new business structure allows both Enthone and Alpha to focus on their core businesses, while providing enhanced value for customers and the industries in which each participates. The demerger enables Alent to invest solely on the needs of the businesses that will result in accelerated technology offerings, targeted market growth, people development, and targeted business investments.
