Schwandorf, 16 December 2014 – In response to the constantly growing demand for fine precipitated
hydroxides mainly in the US market, Nabaltec AG plans to expand the production capacity of its Nashtec
joint venture in Corpus Christi (Texas/USA) by approximately 40%. Appropriate agreements have already
been reached with Nabaltec’s joint venture partner, Sherwin Alumina Company, LLC. The annual
production capacity for fine precipitated aluminum hydroxide, the company’s top-selling product, is to be
expanded to over 30,000 tons. Construction of the new facilities is scheduled to start in 2015 and should
be completed by early 2016. Thanks to steadily increasing demand in the USA and the US dollar zone,
Nashtec has been operating close to full capacity. The planned expansion measures will be implemented
without affecting ongoing operations.

Johannes Heckmann, Member of the Board of Nabaltec AG: “Nashtec has been a success story for
Nabaltec ever since the start of production in 2006. Today, we are the only company in the world to
produce fine precipitated aluminum hydroxides both in the USA and in Europe – and we do so to the same
high standards of quality at both production sites. Nashtec remains a very important component of our
global strategy.”

The Nashtec joint venture was founded by Nabaltec and Sherwin Alumina in 2004. Sherwin Alumina
Company, LLC is a subsidiary of GlencoreXstrata plc. The production of fine precipitated aluminum
hydroxide began in November 2006. The production facilities in Corpus Christi (Texas/USA) are located
adjacent to the Sherwin Alumina plant which supplies primary materials and energy to Nashtec and
enables the company to benefit from the existing infrastructure.
