Clear reduction in expectations for 2009 sales volumes

Extraordinary weak demand for potash fertilizers continues / Clear reduction in expectations for 2009 sales volumes / Additional production curtailment in H2 / European prices reduced in line with the situation on overseas markets / Further significant reduction in revenues and earnings expected in 2009

European agriculture exercised great restraint in the use of potash fertilizers in the spring. Despite the stabilisation of agricultural prices, the demand for fertilizers thus remained very low in Q2 as well. Given the autumn fertilization due in several weeks time too, there is still no sign of any significant upturn in demand in Europe. Until now, K+S expected that the demand for potash and magnesium fertilizers would normalise in the second half of the year and that total sales would be just under 6 million tonnes of goods.

However, in view of the extraordinarily weak sales, K+S has reduced its sales expectations for 2009 to 4.0 to 4.5 million tonnes. Therefore, it has been decided to reduce potash production in the second half of the year by up to 2 million tonnes, following a reduction of 2 million tonnes already implemented in the first half of the year.

Moreover, it has in the meantime been noted on major overseas markets that a price of potassium chloride of USD 735 – 750 per tonne is currently unsustainable for large quantities. The indications rather point to a lower price level. In view of this situation and the upcoming autumn fertilization, K+S KALI GmbH implemented a corresponding reduction in the price of one tonne of granulated potassium chloride in Europe today, lowering it from EUR 555 to EUR 435.

K+S has already forecast a tangible fall in revenues and a significant fall in earnings for 2009. In view of these developments, further significant reductions in revenues and earnings are to be expected in the current financial year. As usual, a quantitative forecast of revenues and earnings will appear with the release of the half-yearly figures on 13 August.
