- Revenues were stable compared to the first half of 2012 but up 4% compared to the second half of 2012, pointing to stabilisation in many end-markets. - Recurring EBITDA was down 10% and recurring EBIT down 15%, affected by less favourable product and regional mix and lower metal prices. - Guidance for full-year 2013 recurring EBIT of €300-330 million was maintained. Commitments to growth programs were unchanged and net debt was further reduced due to positive cash flows.

Revenue evolution pointing to stabilisation
in many end-markets
Revenues stable versus H1 2012
• Volume growth in Catalysis and Energy Materials
compensating for negative impact of lower metal
prices on Recycling
Revenues up 4% versus H2 2012
• Volume growth in Catalysis, Energy Materials and
Performance Materials partly offset by negative
impact of lower metal prices on Recycling

result of cost reduction measures
Higher sales volumes in Rechargeable Battery Materials
driven by demand for high-end portable electronics;
automotive demand growing, albeit from a small base
Revenue growth in Cobalt & Specialty Materials due to
higher refining and recycling volumes, whereas margins
affected by product mix

2013 H1 figures
Revenues and recurring EBIT down vs H1 2012
but up sequentially
Sales volumes in Building Products down due to
recession in the construction sector and harsh winter
conditions at the start of the year
Revenues slightly up in Zinc Chemicals with growing
product demand; lower availability of Zn residues
impacted recycling and refining activity
Stable revenues in Technical Materials and Platinum
Engineered Materials
Continued growth in Electroplating, further benefiting
from the successful introduction of new products
Lower contribution from Element Six Abrasives, affected
by weaker end markets

Recycling
2013 H1 figures
Revenues down 10% and recurring EBIT down 16% due to
impact of lower metal prices
Precious Metals Refining performance reflecting:
• Impact of lower received metal prices, esp. specialty metals
• Higher processed volumes following technical improvements
• Higher intake of residues from non-ferrous metal industries
more than offsetting decrease in end-of-life materials
Lower Au prices caused lower availability of recycling
residues in Jewellery & Industrial Metals
Lower contribution from Precious Metals Management
due to lower overall physical deliveries of precious metals
New contract wins in Battery Recycling
