Trading Statement

Cookson Group PLC 25 May 2006 25 May 2006 AGM TRADING STATEMENT Cookson Group plc ('Cookson' or the 'Company'), a leading materials science company, releases the following statement regarding current trading ahead of today's Annual General Meeting. Our main end-markets and general trading conditions have continued to evolve in line with the guidance given in our Preliminary Results announcement on 14 March 2006. Furthermore, the benefits of the restructuring and cost reduction initiatives undertaken over the past two years continue to materialise in line with our expectations. Whilst metal market prices (notably for tin, gold and silver) have risen sharply in recent weeks, these costs are typically 'pass through' in nature such that the principal impact is to increase reported revenues in our Assembly Materials and Precious Metals businesses. Accordingly, our trading results for the year to date are progressing in line with our previous expectations; with our performance well ahead of the equivalent period last year. Ceramics Global steel production, the most important end-market for the Ceramics division, grew 6% in the first four months of 2006 compared to the same period last year. This continues to be driven by strong growth in China (18%) and India (21%), with production in NAFTA and the European Union being broadly flat year-on-year. Starting at the end of last year and continuing into January 2006, we have implemented a new organisational model and reduced non-production headcount by over 100 people in the US and Europe. The benefit of these cost reduction measures is now being fully reflected in the trading results. The related restructuring charge was included in last year's financial statements. Electronics As expected, end-market growth in our electronics markets is ahead of global GDP but there is some softness in automotive markets. The transition to lead-free solder is continuing to benefit the Assembly Materials sector with 37% of solder revenues in the first quarter now being in lead-free products, up from 32% in the fourth quarter of 2005. Market penetration of the new low silver, lead-free product is also encouraging. There has been no repeat of the significant copper damascene de-stocking issue which negatively impacted the first quarter of 2005. Precious Metals In the US there is evidence of firming in retail markets and our results in this region are also benefiting from the restructuring implemented in the second quarter of 2005. In Europe, retail demand for jewellery remains weak. The first phase of the turnaround strategy in the UK is being implemented through the enhancement of our call centre and internet sales capabilities whilst headcount has been reduced at the trade counters. Our European operations as a whole are now trading profitably, with those in the UK recording a break-even trading result for the year to date. The very significant recent increases in the price of gold and silver are having a mixed impact on our businesses. Because the ownership of the precious metal we use is passed directly from consignors to the customer, we are not directly exposed to the price volatility. Whilst higher precious metal prices typically dampen retail demand for jewellery in the short-term it increases activity in our precious metals recycling operations as the holders of precious metal seek to crystallise the increased value of their holdings. While volatility in precious metals markets continues, the overall impact on the division remains uncertain. Discontinued Operations Formal regulatory approval for the sale of the Laminates business was recently obtained and the transaction was completed on 21 April 2006 for a consideration of US$91 million (£51 million). During the period prior to disposal, the Laminates business had been treated for accounting purposes as a business 'held for sale' and its trading results will be included within 'discontinued operations'. As a consequence, no depreciation charge is recorded for the period up to disposal. Following the restructuring of this business undertaken in 2005, the Laminates sector traded profitably this year in the period up to disposal. Disposals On 31 March 2006, the sale of the Ceramics Fibres business was completed for cash proceeds of US$23 million (£13 million). With the completion of the sale of the Laminates business, this brings the total proceeds from disposals to £114 million, ahead of our target of £100 million by the end of 2006. Outlook Based on general market conditions and our trading results for the first four months of the year to date, we continue to expect an improvement in the overall performance of our operations in 2006. Further announcements A pre-close period trading statement will be issued at the end of June, with Interim results for the six months ending 30 June 2006 being announced on 3 August.
