December 16, 2008 - Norddeutsche Affinerie AG and Cumerio nv/sa now wish to present the combination to the outside world. The new enlarged company will be called Aurubis. „The name represents all that unites us and makes us strong, our common passion for copper“, said Chief Executive Officer, Dr Bernd Drouven, today in Hamburg.   „Aurubis“ is derived from Latin and means „red gold“. „The name puts in a nutshell what copper symbolizes for us and our customers – a metal of extraordinary value. It is the oldest metal in the world and has always been the cornerstone for progress and civilization. This holds true even today: mobile phones, computers, electricity – nothing would function without copper. This special meaning makes us work with passion on our product. To us, copper not only glitters like gold, it is just as valuable“, continued Drouven.  Norddeutsche Affinerie AG’s well-known logo, the blue triangle, will not be changed. It has a long tradition and originally showed three metallurgical tools. It has been modernised several times in the course of the company’s 142 year history.  The official renaming under German commercial law will not take place until after the official resolution is passed at the Annual General Meeting on 26 February 2009. Until then the shares will also still be listed as Norddeutsche Affinerie AG.  The CEO assured that the new name will express the greater international importance of the company. At the same time it is also a commitment to the employees and the current production sites.
