EAX0036 2012-05-09/10:47

While the fertilizer business started well in 2012, the de-icing salt business was exceptionally weak due to weather conditions. As expected, this led to the K+S Group not being able to achieve the high figures of the previous year for revenues and earnings in the first quarter of 2012.

“Despite challenging framework conditions at the start of the year, our potash fertilizer business achieved a very good result“, says Norbert Steiner, Chairman of the Board of Executive Directors of K+S Aktiengesellschaft on the occasion of the Company’s Annual General Meeting in Kassel. „We were thus able to significantly mitigate the sharp decline for de-icing salts which was entirely due to weather conditions. After the demand for fertilizers started to recover at the end of the first quarter and should further continue during the course of the year, we still see good prospects and are holding to the forecasts for 2012 as a whole. This year too, we should earn a high premium on our cost of capital“, Steiner continues.

Rising fertilizer demand at the end of the first quarter

In the wake of the European sovereign debt crisis, the trade sector was more cautious in its early stocking-up of fertilizers at the end of 2011 and the beginning of 2012. Moreover, winterkill damage resulting from very dry and cold weather led to a postponement of the European spring season. However, throughout the first quarter, the price level for agricultural raw materials continued to offer attractive income prospects for farmers and therefore an incentive to increase yields per hectare also through the optimal use of fertilizers. Against this background, at the end of the first quarter, there was an upturn in demand for potash fertilizers, especially after the contractual negotiations with China for the first half of 2012 were concluded with unchanged terms in mid-March. The global market price level for potassium chloride was tangibly higher in the first quarter of 2012 than in the same quarter of the previous year. In comparison to the average of the fourth quarter of 2011, prices moderately decreased in some regions; however, since the conclusion of the contracts in China, international potash prices tend to get stronger again.

For nitrogen fertilizers too, in Europe, the first two months of the year were marked by a certain buying restraint, until demand recovered towards the end of the first quarter. The prices for nitrogen fertilizers were moderately higher than the average for the same quarter of the previous year, but they decreased slightly compared to the average for the fourth quarter of 2011 as a result of lower input costs for ammonia.

Unusually weak demand for de-icing salt

As a result of the very mild and partly dry weather conditions at the beginning of the year, the demand for de-icing salt in Western Europe was unusually weak, particularly compared to the above-average first quarter of 2011, but also compared to the long-term average sales volume. In the first quarter of 2012, the price level was slightly higher than in the same quarter of the previous year and was relatively stable compared to the average for the fourth quarter of 2011.

On the US East Coast, too, the demand for de-icing salt was very weak due to the unusually mild winter, and it was below average in the de-icing salt regions of Canada. Most producers responded to high inventories by cutting back production. A slight reduction in price was noted particularly on the US East Coast and in other de-icing salt regions of the USA.

First-quarter revenues below figure for previous year due to weather conditions

Revenues in the first quarter amounted to € 1,438.1 million, a decrease of € 188.8 million or 12 % relative to the figure for the previous year. This decrease is attributable exclusively to lower revenues in the Salt business segment due to weather conditions. Revenues in the Potash and Magnesium Products business segment were slightly above the figure for the previous year, revenues in the Nitrogen Fertilizers business segment increased by approximately 10 %. In the first three months of the year, 40 % of revenues were generated in the Potash and Magnesium Products business segment, followed by Salt (32 %) and Nitrogen Fertilizers (25 %). In Europe, K+S generated a share in revenues of approximately 50 %, followed by North America (25 %), South America (12 %) and Asia (11 %).

Operating earnings below previous year due to salt business

In the first quarter of 2012, earnings before interest, taxes, depreciation and amortisation (EBITDA) fell by 21 % to € 337.0 million (Q1/11: € 424.9 million).

In the first quarter of 2012, operating earnings EBIT I reached € 281.1 million and were thus € 87.3 million (24 %) lower than in the same quarter of the previous year. The Potash and Magnesium Products business segment was able to further improve its earnings and achieved its best first-quarter earnings yet. By contrast, in the Nitrogen Fertilizers business segment, earnings were slightly lower than the peak figure of the previous year. As a result of the weak de-icing salt business, operating earnings of the Salt business segment decreased very sharply relative to the extraordinarily good result for the same quarter of the previous year.

Adjusted earnings before and after taxes correspondingly lower

In the first quarter, adjusted earnings before income taxes reached € 266.1 million and were, in line with the development of operating earnings, € 87.1 million or 25 % below the figure for the previous year. Adjusted Group earnings decreased in the first quarter by € 68.2 million or 26 % to € 193.4 million.

Adjusted earnings per share in the first quarter at € 1.01 (Q1/11: € 1.37)

Adjusted earnings per share in the quarter under review amounted to € 1.01 and were thus approximately 26 % lower than the figure for the previous year of € 1.37. They were computed on the basis of 191.40 million no-par value shares, being the average number of shares outstanding (Q1/11: 191.20 million no-par value shares).

Outlook unchanged: Revenues stable, moderate decline in operating earnings

In the financial year 2012, revenues of the K+S Group should remain stable in comparison to the previous year. While in the Potash and Magnesium Products business segment, on the basis of the currently achieved potash price level, a moderately, and in the Nitrogen Fertilizers business segment, a slightly increasing development of revenues can be assumed, in the Salt business segment tangibly (previously: moderately) lower revenues are expected. The revenue forecast assumes an average US dollar exchange rate of 1.33 USD/EUR (previously: 1.32 USD/EUR); 2011: 1.39 USD/EUR).

In the financial year 2012, operating earnings EBIT I of the K+S Group should decrease moderately in comparison to last year’s figure. In the Potash and Magnesium Products business segment, it is assumed that operating earnings could again approach those of the good earnings achieved last year. The Nitrogen Fertilizers business segment should be able to achieve earnings at the level of the previous year. In comparison to last year, which benefited from above-average volumes of de-icing salt, operating earnings of the Salt business segment will probably decline strongly.

Moderately declining Group earnings expected

The adjusted Group earnings after taxes should also decline moderately in 2012 in line with the development of operating earnings. This estimate is based not only on the effects described for revenues and operating earnings, but also on:

• the expectation of consistently attractive agricultural prices,
• the customary, purely technical forecast policy, which maintains the currently achieved potash price level unchanged for the remainder of 2012,
• a sales volume in the Potash and Magnesium Products business segment at about the same level as in the previous year (2011: 6.9 million tonnes),
• a sales volume of crystallised salt of less than 19 million tonnes (previously: a good 19 million tonnes; 2011: 22.7 million tonnes), of which less than 10 million tonnes de-icing salt (previously: about 10 million tonnes; 2011: 13.3 million tonnes). For the fourth quarter, this, as usual, assumes the average of multi-year de-icing salt sales volumes.
• a largely unchanged financial result,
• a slightly higher adjusted Group tax ratio of 27 % to 28 % (2011: 26.1 %).

This outlook still includes the Nitrogen business segment, since the sale of K+S Nitrogen was announced after the outlook was set up on 2 May 2012. However, the sale of K+S Nitrogen does not change the outlook statement: stable revenues and moderately decreasing operating earnings can still be expected for the year 2012 compared to the pro-forma adjusted year 2011.

The transaction, with an enterprise value of EUR 140 million for K+S Nitrogen, is likely to be closed at the end of the second quarter of 2012. The effective economic date of the transfer is 31 March 2012. The sale is subject to a number of factors, including approval by the EU antitrust authority.

For K+S, the sale will generate a book profit of around EUR 70 to 80 million, depending on the net earnings of K+S Nitrogen generated by the time the transaction is closed together with other effects. From now on, K+S Nitrogen will be stated as a “discontinued operation”. In financial year 2011, K+S Nitrogen generated revenues of EUR 1,156.8 million and operating earnings EBIT I of EUR 69.4 million.

“We are pleased to have found a well-suited new owner for K+S Nitrogen in EuroChem. Against the backdrop of the recently concluded sale of the fertilizer activities of BASF in Antwerp, the sale to EuroChem is the best option from the perspective of K+S, but also of the employees of K+S Nitrogen,” says Norbert Steiner, Chairman of the Board of Executive Directors of K+S Aktiengesellschaft. “I would like to express my particular thanks to the employees of K+S Nitrogen for their extraordinary commitment in recent years,” Steiner continues.

EuroChem CEO Dmitry Strezhnev commented: “K+S Nitrogen is a natural extension to our recently acquired EuroChem Antwerpen operations. This acquisition provides us with a world-renowned platform while further securing our competitiveness in key markets worldwide. We welcome the highly skilled staff of K+S Nitrogen and our clients and partners may rest assured that the high level of service they have grown accustomed to with K+S Nitrogen will be maintained.”

The strategy of the K+S Group provides for growth in the Potash and Magnesium Products and the Salt business segments in particular and for focusing management resources and financial means on this accordingly. Against this background, K+S had sold the business activities of COMPO to the investment company Triton last year.

• High demand for fertilizers and strong salt business once again
• Revenues rise by 11% to € 5.2 billion
• Operating earnings EBIT I reach € 976 million (+37%), the second-best result in the history of the Company
• Adjusted earnings per share from continued operations improve, reaching € 3.52 (+49%)
• Adjusted earnings per share at € 3.04 (+30%)
• Dividend proposal raised significantly: € 1.30/share (2010: € 1.00)

Q4/2011

• Fertilizers: More cautious management of early stocking-up by trade sector; Salt result under record level of 2010 due to weather conditions
• Revenues at € 1.30 billion (Q4/2010: € 1.29 billion)
• Operating earnings EBIT I increase by 9% to € 216.9 million
• Adjusted earnings per share from continued operations at € 0.80 per share (Q4/2010: € 0.78)

Attractive prospects for the two coming years

• Outlook for 2012: Revenues stable and earnings moderately decreasing due to mild winter
• Promising outlook for 2013: Revenues should rise slightly, operating earnings will probably increase moderately

The K+S Group looks back at 2011 as a year that was very successful. “Despite the general uncertainty connected with the sovereign debt crisis in Europe, in the past financial year, we managed to achieve the second-best result so far in the Company's history”, says Norbert Steiner, Chairman of the Board of Executive Directors of K+S Aktiengesellschaft on the occasion of the Company’s financial report press conference.

High demand for fertilizers

The fertilizer business was characterised by strong demand particularly in the first nine months, before a more cautious management of early stocking-up by the trade sector emerged in the fourth quarter. The prices of important agricultural products were at a consistently attractive level in the course of the year, which offered a significant incentive for farmers worldwide to increase the yield per hectare by using more fertilizer.

Salt business achieves record level of previous year

In the Salt business sector, the wintry weather conditions in the first quarter of 2011 both in North America and Europe resulted in very high demand. It thus proved possible to again achieve the record sales volumes of the previous year despite the mild winter in the fourth quarter. The salt business in 2011 was thus again above average.

Revenues increase by 11% to € 5.2 billion

In financial year 2011, the K+S Group achieved revenues of € 5,150.9 million, which was 11% above the figure for the previous year. The increase in revenues is particularly attributable to positive price effects, which were able to more than make up for the slightly negative currency and volume effects. While the Potash and Magnesium Products and Nitrogen Fertilizers business segments posted significant revenue growth, the Salt business segment was able to maintain revenues almost at the high level of the previous year.

In Europe, revenues of € 2.6 billion (+11%) were achieved. This region therefore accounted for half of total revenues. North America achieved a share in revenues of 23% and South America one of 12%, while Asia accounted for 11% of total revenues.

Operating earnings up significantly

During the year under review, earnings before interest, taxes, depreciation and amortisation (EBITDA) rose by 28% to € 1,217.7 million (2010: € 953.0 million). The increase was, in particular, due to the significant improvements in earnings in the Potash and Magnesium Products and Nitrogen Fertilizers business segments. At 23.6%, the EBITDA margin also reached a very pleasing level (2010: 20.6%).

The key control variable of the K+S Group, operating earnings EBIT I, increased by € 261.2 million or 37% to € 975.7 million (2010: € 714.5 million). At 18.9%, the EBIT margin also reached a very good level (2010: 15.4%).

The Potash and Magnesium Products and Nitrogen Fertilizers business segments increased their earnings above all due to fertilizer prices rising over the year. The earnings of the Salt business segment were below the figure for the previous year, since although the de-icing salt business was above average, due to a different regional mix it did not achieve the record level of the previous year.

Adjusted earnings before and after taxes also strongly improved

Adjusted earnings before incomes taxes were € 911.8 million and thus rose by € 317.3 million or 53% in comparison to the previous year's figure. At € 673.6 million, the adjusted Group earnings from continued operations were € 219.8 million or about 50% above the previous year’s level (2010: € 453.8 million). The main reasons for this were the sharply increased operating earnings and a significantly improved financial result.

For the year under review, adjusted earnings per share from continued operations amounted to € 3.52 – an increase of about 50% over the previous year’s figure of € 2.37. Adjusted earnings per share including discontinued operations reached € 3.04 (2010: € 2.33).

4th quarter of 2011: Higher earnings despite subdued environment

The consequences of the sovereign debt crisis became noticeable also in the fertilizer business towards the end of the year. With the 2008/2009 financial crisis still fresh in mind, the trade sector felt uncertain at the end of the year and, for the time being, postponed the customary early stocking-up of fertilizers.

In the West European de-icing salt business, the early stocking-up, which extended even into the fourth quarter, resulted in an overall satisfactory start to the winter season 2011/2012 despite the relatively mild weather. However, in the United States and in Canada too, the season began below average due to the also rather mild weather.

At € 1,300.2 million, revenues of the K+S Group in the fourth quarter of 2011 were somewhat higher than the figure for the previous year (€ 1,285.3 million).

During the fourth quarter, earnings before interest, taxes, depreciation and amortisation (EBITDA) rose by about 11% to € 290.8 million (previous year: € 261.4 million). Operating earnings EBIT I improved in the fourth quarter by about 9% to € 216.9 million (previous year: € 198.6 million). The price-related increase in earnings in the Potash and Magnesium Products business segment managed to more than make up for the significant decrease in earnings in the Salt business segment.

Adjusted Group earnings from continued operations rose in the fourth quarter by 3% to € 153.3 million (Q4/2010: € 148.8 million) after the previous year’s quarter had benefited from a low tax ratio.

Board of Executive Directors and Supervisory Board propose dividend of € 1.30 per share

The Board of Executive Directors and the Supervisory Board will propose to the Annual General Meeting that the dividend for the past financial year should be raised in accordance with the significantly increased earnings, and € 1.30 per share be paid (2010 dividend: € 1.00). This would correspond to a dividend pay-out ratio of about 43%.

K+S Group with attractive prospects

K+S’s Chairman of the Board of Executive Directors, Norbert Steiner, on the expected course of business: “Despite all the macroeconomic uncertainties, 2012 should nevertheless be another good year for the K+S Group. The current pricing level for agricultural raw materials offers attractive income prospects for farmers and should therefore lead to a positive development in fertilizers demand in those sales regions of relevance for us. However, for the Salt business, due to the weather-related unusually poor start to the de-icing business, we are anticipating significantly lower volumes of business compared to the above-average performance in 2011. In sum, K+S Group revenues will probably remain stable for 2012, while operating earnings and adjusted earnings after taxes should, however, decrease moderately due primarily to the muted demand for de-icing salt. Nonetheless, without the impact of last year’s disposal of the COMPO business, there is a good chance for an at least stable dividend for the year 2012.”

In 2013, revenues of the K+S Group should increase slightly in comparison to 2012. Owing to the high profitability of the Potash and Magnesium Products business segment and on the basis of an again assumed normal winter business in line with the long-term average historical volumes of de-icing salt, there are realistic opportunities of a moderate increase in operating earnings in comparison to 2012. This should also positively impact the adjusted Group earnings after taxes. A raising of the dividend is therefore possible.

Shareholders, investors, representatives of the press and all other interested parties are invited to follow the conference via a live webcast at (www.k-plus-s.com/en/audio-und-video/cc.html) or via telephone (+49-69-6677-75757; PIN 3564773#).

Forward-looking statements
This press release contains facts and forecasts that relate to the future development of the K+S Group and its companies. The forecasts are estimates that we have made on the basis of all the information available to us at this moment in time. Should the assumptions underlying these forecasts prove not to be correct or risks arise – examples of which are mentioned in the risk report – actual developments and events may deviate from current expectations. Outside statutory disclosure provisions, the Company does not take any obligation to update the statements contained in this press release.

At its meeting today, the Supervisory Board resolved to propose to the Annual General Meeting on 9 May 2012 that Dr. Bethke be re-elected to the Supervisory Board. His mandate ends at the close of the ordinary Annual General Meeting 2012. The members of the Supervisory Board further intend to once again elect Dr. Bethke as chairman of the Supervisory Board in the event of his successful re-election to the Supervisory Board. From 1991 to 2007, Dr. Bethke (69) had been chairman of the Board of Executive Directors of K+S Aktiengesellschaft and, also as chairman of the Supervisory Board, he contributed with his knowledge and experience considerably to the success and internationalisation of the K+S Group.

Moreover, on 9 May 2012, the Annual General Meeting is to decide on an altering of the remuneration of the Supervisory Board. The Board of Executive Directors and the Supervisory Board consider that an exclusively fixed remuneration of the members of the Supervisory Board better takes account of the consulting and controlling function of the Supervisory Board, which generally exists independently of the success of the Company, than the existing form of remuneration, which also includes a variable component. Furthermore, it appears reasonable to adjust the remuneration for the activity in the committees of the Supervisory Board to the greater workload and complexity. The proposed change to the Supervisory Board remuneration is intended to ensure that in future too, members can be found for the Supervisory Board who have a high level of competence and long-term as well as international experience in the governance of and in providing advice to companies or business-related institutions.

A member of the Supervisory Board shall in future receive fixed annual remuneration of € 100,000 (previously: € 55,000). The previous annual variable remuneration, which was determined by the amount of the return on total investment achieved by the K+S Group in the respective financial year and could amount to a maximum of € 45,000, will cease and not be replaced. The chairman of the Supervisory Board shall receive twice this amount and the vice-chairman one-and-a-half times the amount of such remuneration. The work on the committees of the Supervisory Board has increased significantly in scope and complexity in recent years. The members of the audit committee shall therefore receive annual remuneration of € 15,000 each (previously: € 7,500), and the members of the personnel committee annual remuneration of € 7,500 each (previously not remunerated). For his or her activity on the nomination committee, each member shall receive annual remuneration of € 7,500 (previously not remunerated) if at least two meetings have taken place in the respective year. The chairmen of these committees shall receive twice this amount and the vice-chairman one-and-a-half times the amount.

Resume Dr. Burkhard Lohr

During the approximately three-hour mine trips, visitors at Merkers dive deep into the underground world, while simultaneously taking a thrilling journey through time. Experienced miners give clear explanations of the history, technical development and economic importance of potash mining on the Werra and are able to tell many an entertaining story.

The destinations of the round trip through the mine, whose beginnings date from the start of the 20th century, and which was once the world’s largest potash mine, include the historic gold room in which US soldiers found the treasures of the Reichsbank at the end of the war, an exhibition of large equipment used for potash extraction, and the multimedia simulation of a mining detonation. The undisputed highpoint is, however, the crystal grotto at a depth of 800 metres. It casts a spell over the visitors with its gigantic salt crystals, which cast their magical glow in a delightful light and music show. There are good reasons why the crystal grotto has been included on the list of national geotopes.

In addition to the guided tours, many different concerts and sporting events are hosted in the Merkers Adventure Mine, which also attract many visitors. For example, on 26 February and already for the sixth time, the “crystal marathon” will be held. Runners from Germany and abroad have already signed up to run.

A supplementary offer is Down Under, since 2009 the world's deepest climbing and experience park. Here company events and teambuilding training can be held at numerous points down to a depth of twelve metres.

The special arrangements, which are individually tailored to the wishes of the guests, are proving increasingly popular. This offer ranges from underground weddings through children’s birthdays to the holding of company celebrations, conferences or presentations.

Guided tours in the Merkers Adventure Mine take place from Tuesdays to Sundays from 9:30 am to 1:30 pm. Reservations are recommended.
