COOKSON GROUP PLC ("Cookson" or "the Group")

INTERIM MANAGEMENT STATEMENT

In advance of a number of scheduled investor meetings and given that Cookson's outlook for the first half of 2010 has improved since its preliminary results announcement on 2 March 2010, the Group has brought forward to today its Interim Management Statement, which now covers the period from 1 January to 25 April, 2010.

Current expectations for H1 2010

·;Reported revenue up 13% to 15% on H2 2009 (25% to 27% on H1 2009)

·;Underlying revenue up 8% to 10% on H2 2009 (22% to 24% on H1 2009)

·;Half year trading profit in the region of £110m to £115m, up 15% to 20% on H2 2009 (£95m)

Current trading and outlook

Global steel production, notably for Europe and NAFTA, has grown at a faster rate in the first quarter of 2010 than previously anticipated. Foundry castings end-markets have shown some improvement in the emerging economies, but remained low in Europe and NAFTA. Electronics end-markets have shown faster growth in the first quarter of 2010 than previously anticipated. The Precious Metals division continues to benefit from very high levels of reclaim business. As a result of these improvements, reported revenue for the first half of 2010 is now expected to be in the region of 13% to 15% ahead of the second half of 2009 (25% to 27% ahead of the first half of 2009). Underlying revenue, which is revenue at constant exchange rates adjusted for the impact of commodity metal prices, for the first half of 2010 is expected to be in the region of 8% to 10% ahead of the second half of 2009 (22% to 24% ahead of the first half of 2009).

Following the extensive cost reduction measures implemented since the fourth quarter of 2008, the majority of which were completed by mid-2009, profit "drop-through" from the increased revenue in the first quarter has been strong. As a result, trading profit for the first half of 2010 is expected to be in the region of £110m to £115m, 15% to 20% above that reported for the second half of 2009 (first half 2009: £17m; second half 2009: £95m). With the geographic distribution of profit before tax currently anticipated (which includes better than expected profitability in the US), the effective tax rate on headline profit before tax (before share of joint ventures) for full year 2010 is now expected to be marginally lower than the previous guidance of 30%.

Global steel production in the first quarter of 2010 (according to the World Steel Association) was 4.7% higher than the fourth quarter of 2009. Excluding China (China currently accounts for less than 10% of the Ceramics division's steel-related revenue), the growth in steel production between quarters was 2.3%, with growth in Europe and the US of 4.6% and 9.1% respectively. On 20 April 2010, the World Steel Association issued a new short range forecast for global apparent steel use, revising the 2010 growth estimate to 10.7% from its previous forecast of 9.2% (world excluding China revised to 14.4% from 13.1%). They also published for the first time a forecast for 2011, which predicts growth in global apparent steel use of 5.3% (world excluding China 7.4%). Prospects in the later cycle foundry castings market remain less clear. Major castings users are not reporting any material upturn in production activity to date but are anticipating some level of improvement later in the year. In March 2010, JD Power increased its forecast for global truck production growth in 2010 from 15.6% (as per their December 2009 report) to 18.2%.

For electronics end-markets, several market commentators have recently been increasing their forecasts for end-market demand. For example, in April 2010 Henderson Ventures revised its forecast for year-on-year global electronics production growth to 8.3% in 2010 and 9.5% in 2011 (6.7% and 8.5% respectively as per their February report).

While underlying demand in the Group's end-markets has clearly improved overall, uncertainty as to macro-economic conditions going forward remains. In addition, the level of inventory re-stocking by customers, which may be having the effect of increasing demand for Cookson's products in the short-term, remains unclear. We therefore remain cautious in anticipating further out-performance in the second half of the year. Nonetheless, given our much reduced cost base, performance should continue to improve as further end-market recovery is confirmed.

Financial position

During 2009, working capital was reduced by just under £150m as the Group's operations were adapted to the much reduced level of activity. In line with previous guidance, working capital trends in 2010 are expected to revert to more normal seasonality, with a build up of working capital in the first half of the year and some reduction during the second half. Overlaying this normal seasonality, working capital during 2010 in total is expected to increase reflecting the continued recovery in business activity.

The Group has very substantial liquidity headroom within its committed debt facilities, which will total just over £800m following the scheduled repayment of US$135m of US Private Placement Loan Notes in early May 2010. The principal maturities for these facilities are late 2011 and 2012. Net debt as at 31 December 2009 was £371m.
