3rd Quarter Trading Update

Cookson Group PLC 07 November 2003 7 November 2003 COOKSON GROUP THIRD QUARTER TRADING UPDATE Cookson Group plc, the international materials technology company, today made the following comments on trading for the third quarter of 2003 and the outlook for the remainder of the year. Activity levels in the Group's markets improved in September; this followed a quiet start to the third quarter which was mainly due to routine summer holiday shutdowns by many of the Group's customers in the USA and Europe. This positive momentum in September has been maintained in October. In the Electronics division, sales for continuing operations of £140 million were 4% lower than the same quarter last year, although sales improved considerably in September, being up 2% over the previous year. This positive trend was also evident in October with sales for the month up on both last year and September 2003. Asia-Pacific continues to be the division's best performing region and, in line with the wider electronics industry, activity began to improve in the USA. The division recorded an operating profit of £3 million for the third quarter. This represents a £2 million improvement over the same period a year ago and arose largely as a result of previously announced cost cutting measures. The Assembly Materials and Chemistry sectors of the Electronics division continued to operate profitably during the third quarter. The benefits of the licensing and distribution agreement with ATMI which was announced in May - relating to the Chemistry sector's copper electrochemical deposition business - are beginning to be realised. In the Laminates sector, the impact of the rationalisation programmes announced earlier in the year resulted in further meaningful reductions in operating losses. In August, the Laminates sector broadened its product range through a licensing arrangement with GE for its GETEK(R) laminates technology, the benefits of which will begin to become evident in the fourth quarter. As announced on 5 November, Speedline, the assembly equipment sector of the Electronics division, was sold to KPS Special Situations Fund II LP for a total consideration of approximately US$10 million (£6 million). In the third quarter of 2003, Speedline had sales of £16 million and generated an operating loss of £4 million. In the Ceramics division, sales of £170 million for the third quarter were 3% lower than last year. Despite this, operating profit of £11 million was £1 million higher than the same quarter a year ago, largely as a result of better product mix and lower operating costs. Global steel production was up 5% over the same quarter last year but production was less robust in the division's major steel related markets, the USA and the EU, although production levels began to recover in the USA in October. Other steel producing regions generally performed well. After a disappointing second quarter, the Glass sector began to show signs of recovery in the third quarter. In the Precious Metals division, a slower start than normal to the third quarter resulted in sales of £75 million being 4% lower than last year. However, activity levels picked up in September as the division began to experience the signs of the traditional seasonal pattern and sales for that month were 3% higher than a year ago. Further positive progress was also evidenced in October. Third quarter operating profit for the division of £2 million was £1 million lower than the same quarter a year ago. The Group recorded profit before tax of £5 million in the third quarter of 2003 compared with a £1 million loss in the same quarter last year. The improvement arose from higher operating profit from continuing operations and from markedly lower interest costs. This, in turn, resulted in profit before tax for the Group of £10 million for the nine months ended 30 September 2003 which is £23 million better than the £13 million loss incurred for the same period last year. The outlook for the remainder of 2003 is that underlying trading conditions are expected to remain essentially unchanged from those experienced in September and October. As a consequence - and in line with guidance given at the time of the release of Cookson's interim results in July - profit before tax for the year is expected to be in line with current market expectations. The Company will hold a conference call for analysts and shareholders today at 8:00am which will be broadcast live at www.cooksongroup.co.uk.
