Constellium NV : to build greenfield manufacturing facility for automotive structures in Bartow County, Georgia, USA

24 November 2015

Amsterdam, November 24, 2015 - Constellium N. V. (NYSE and Euronext: CSTM) announced today that it will construct a new manufacturing facility in Bartow County, Georgia, in response to growing demand for its automotive structures in North America. This project represents a $20 million investment by Constellium and an additional $12 million investment by developer Seefried Properties, for a total project value of $32 million. Construction of the plant will begin in early 2016 with start of production anticipated in 2017. Constellium expects to create approximately 150 high-tech manufacturing jobs at this location by 2019.

'The new Georgia plant demonstrates Constellium's commitment to work in partnership with automakers in North America and to be near their assembly plants,' said Paul Warton, President of Constellium's Automotive Structures and Industry business unit. 'This expansion of our footprint in the Southeast United States will allow us to better serve our automotive customers and to respond the industry's growing demand for aluminium structural parts to lighten vehicles, improve fuel economy and reduce environmental impact.'

The planned 84,000 square foot greenfield facility may be expanded up to 220,000 square feet to adapt to customers' supply needs in the future.

'Georgia has a strong business climate and an advanced technical education network to provide a skilled workforce for our operations,' commented Eric Krepps, Vice President and General Manager of Constellium Automotive Structures North America. 'We are grateful for the warm welcome we have received from the State of Georgia, Bartow County and a number of partners to help achieve our business goals.'
