SQM Reports Earnings for the First Quarter of 2009

SANTIAGO, Chile - Sociedad Quimica y Minera de Chile S.A. (SQM) (NYSE: SQM; Santiago Stock Exchange: SQM-B, SQM-A) reported today earnings for the first quarter of 2009 of US$86.3 million (US$0.33 per ADR), an increase of 33% with respect to the same period of 2008, when earnings totaled US$64.8 million (US$0.25 per ADR). Operating income reached US$119.5 million (37% of revenues), 39% higher than the US$86.2 million (26% of revenues) recorded during the first quarter of 2008. Revenues totaled US$320.9 million for the first quarter, representing a decrease of 2% over the US$326.3 million reported in the same period of 2008.

SQM’s Chief Executive Officer, Patricio Contesse, stated, “Considering the current global economy and the difficult circumstances of world markets in general, the increase in our quarterly operating income and net income is very good news. The Company’s different business lines prevent us from depending on a single product or market and provide us with diversified sources of revenue that allow us to deliver higher operating margins.” He continued, “Higher sales prices during the first quarter of the year compared to the same period of the previous year combined with lower operating costs have allowed us to offset the lower sales volumes in our SPN, iodine and lithium businesses, which have in general followed the downward trend observed in different sectors of the economy during recent times. As anticipated, higher production levels of potassium chloride have translated into significantly higher sales volumes and have positively impacted our margins.”

Mr. Contesse concluded, “We remain confident that the fertilizer and industrial markets that use our products should recover by the second semester, increasing results in the second half of the year compared to the first half of this year.”
