[Translation] Ref. PDI/BK-BS-038/2005 13 May 2005 To : President The Stock Exchange of Thailand Re: Clarification on the companys performance in the first quarter of 2005 Attached please find a copy each of Thai and English version of the reviewed company only interim financial statements and consolidated interim financial statements of Padaeng Industry Public Company limited for the quarter ended 31 March 2005 for the SETs information. For the first quarter of 2005, total sales of metal totalled 25,855 tons, a 2.2% decrease from 26,436 tons of the same quarter last year. Even as sales volume decreased, sales value rose owing to a rebound in LME zinc price from 1,070 USD to 1,317 USD or a 23.1% increase from the same quarter last year. Benefit from higher LME zinc price and silicate feed in the production process, the company gross profit increased by 65.2% even though the company still suffered from freight costs, which have increased steadily since the previous year and the lower treatment charges for concentrates. Bearing these factors in mind, the company reported the first quarter result as follows: From the companys statement of income on Equity Method, the companys total revenues from sales and services was Bt1,495.5m which increased from the same quarter of year 2004 by Bt248.4m or 19.9% increase. There was a net profit of Bt138.8m or a net gain per share of Bt0.61 compared to a net gain per share of Bt0.38 in the same period of year 2004. From the companys consolidated statement of income, total revenues from sales and services was Bt1,499.4m which increased by Bt250.4m or a 20.1% increase from the same quarter of last year. There was a net profit of Bt134.6m or a net gain per share of Bt0.60 compared to a net gain per share of Bt0.37 in the same quarter of year 2004. Please be informed accordingly.
