Brilon, November 10, 2011: The SDAX-listed company CENTROTEC Sustainable AG again posted record revenue in the third quarter of the current financial year. Revenue for the quarter climbed 9.2 % to EUR 143.8 million and therefore just outstripped the 8.2 % growth rate for the first nine months of 2011, which took the total for the year to date to EUR 378.1 million (previous year EUR 349.4 million). The Climate Systems segment contributed most to this growth, expanding by 11.1 % to EUR 266.1 million (previous year EUR 239.6 million); Dreyer & Bosse Kraftwerke GmbH, acquired at the end of August, was included here for the first time.

Brilon, November 7, 2011: CENTROTEC Sustainable AG’s earnings for the third quarter of 2011 will reveal non-recurring, non-cash effects as a result of an adjustment to the value of the investment in CENTROSOLAR and the streamlining of the business portfolio for photovoltaic activities. At its meeting today, the Management Board of CENTROTEC resolved that due to the uncertainty of the photovoltaic market an impairment of approx. EUR 15 million will be booked for the valuation of the 26 % interest in CENTROSOLAR Group AG, leading at the level of the financial result to an exceptional write-down on the value of the investment by the same amount.

Brilon, August 26, 2011: The SDAX-listed company CENTROTEC Sustainable AG is acquiring a 38 % interest in Industrial Solar GmbH, Freiburg by way of a capital increase. The latter company, which has arisen through a succession of spin-offs from the Fraunhofer Institute for Solar Energy Systems in Freiburg, has broad technology know-how in the field of solar process heat and solar cooling. The highly efficient Fresnel collector system, for applications in the temperature range from 130°C to approx. 400°C and covering a spread of thermal outputs from several hundred kW to the double-digit megawatt range, offers a broad range of industrial applications for solar process heat and solar cooling.

Brilon, August 11, 2011: the SDAX-listed company CENTROTEC Sustainable AG achieved organic growth of 7.7 % in the first half of 2011 and posted another revenue record of EUR 234.3 million (previous year EUR 217.7 million). The core segment Climate Systems served as the bedrock of this steady corporate development, with its revenue growing disproportionately by 11.7 % to EUR 161.4 million (previous year EUR 144.5 million). The smallest segment, Medical Technology & Engineering Plastics, was yet again the fastest-growing area with revenue up 23.4 % to EUR 21.1 million (previous year EUR 17.1 million). Equally, core business in the Gas Flue Systems segment made positive progress but this was insufficient to counterbalance the sharp downturn in certain peripheral areas, such as in due to short term regulatrory changes specifically weak solar components business in France; the net result was therefore a 7.5 % fall in revenue to EUR 51.8 million compared with the very strong prior-year revenue of EUR 56.0 million. In the second half of the year growth is expected in this segment.

Brilon, August 10, 2011: the Wolf Group, Mainburg, a fully-owned subsidiary of the SDAX-listed company CENTROTEC Sustainable AG, is acquiring 80 % of the shares of Dreyer & Bosse Kraftwerke GmbH, Gorleben, with effect from August 31, 2011. The latter company, founded in 1997, has a full product range for biogas processing in the shape of biogas treatment plants and combined heat and power (CHP) units. In recent years it has achieved organic growth in excess of 20 % annually, and has been branching out internationally alongside its core market Germany. In 2010 the company, which has around 80 employees, generated approx. EUR 22 million in revenue.

Brilon, May 12, 2011: the SDAX-listed company CENTROTEC Sustainable AG generated record revenue of EUR 112.3 million in the first quarter of 2011. Compared with the previous record from one year earlier (EUR 103.1 million), this represents organic growth of 8.9 %. This development was underpinned especially by 13.9 % revenue growth for the largest segment, Climate Systems, to EUR 76.5 million (previous year EUR 67.2 million), which was accompanied by growing market shares and profit margins. The Medical Technology & Engineering Plastics segment, too, bettered the previous revenue record from 2008 with 26.2 % revenue growth to EUR 10.7 million (previous year EUR 8.5 million). Compared with the very strong prior-year quarter, revenue for the Gas Flue Systems segment was down 8.7 % to EUR 25.0 million (previous year EUR 27.4 million), mainly as a result of weaker French business.

Brilon, March 29, 2011 – CENTROTEC Sustainable AG ended the 2010 financial year with the highest revenue (EUR 479.7 million) and the best earnings figures (EUR 36.2 million EBIT) in the history of the group. Earnings in particular rose overproportionally at all levels and were well up on both the previous year and the previous record-best figures from 2008. These results, achieved in a market environment that remained difficult, meant that the forecasts upgraded on multiple occasions during the year were comprehensively met. This profitable growth was achieved in particular thanks to the even stronger market position for the CENTROTEC companies in the Climate Systems segment in 2010. As well as the further improvement in its position in the German heating market, there was substantial growth in export business particularly in Southern and Eastern Europe. Based on the renewed rise in earnings and the further substantial reduction in net borrowings (EUR 71.1 million, previous year EUR 86.5 million), the group is planning to distribute its first ever dividend of EUR 0.10.

Brilon, January 25, 2011 – Based on provisional, unaudited figures CENTROTEC Sustainable AG, Brilon, fully achieved the forecast for the 2010 financial year that was upgraded several times in the course of that year. Revenue will reach EUR 480 million and therefore lie within the bandwidth of EUR 480 to 500 million as forecast at the start of the year. The operating result (EBIT) will be up by around one-quarter and consequently fully reach the forecast that was revised upwards in-year to EUR 36 to 37 million (original forecast EUR 30 to 32 million, previous year EUR 29 million). Earnings per share (EPS), too, are fully within the forecast range of EUR 1.50 to 1.60 that was upgraded twice during the year (from originally EUR 1.10 to 1.20).

Brilon, November 11, 2010: Record revenue of EUR 349.4 million was achieved in the first nine months of 2010. This total represents growth of 6 % on the previous year, and also a higher level than in the previous record year of 2008. Revenue growth was achieved in almost every major domestic and international market.
The group further consolidated its strong market position in its core markets. Maintaining a trend stretching back over two years, it again significantly increased its share of the German heating market in Q3.

Brilon, October 6, 2010 – CENTROTEC Sustainable AG is increasing its full-year EBIT forecast for 2010 to EUR 36-37 million (from a previous EUR 30-32 million) and its earnings per share (EPS) forecast to EUR 1.50-1.60 (from a previous EUR 1.30-1.40). Positive business progress continued across all areas of the company in the third quarter that has just ended. Thanks to the outstanding market position of the CENTROTEC companies, the competitive product range of integrated system solutions for saving energy in buildings and the increasing focus on renewable energy, it again succeeded in increasing its market share in its core markets. Revenue was boosted from the already healthy level of the prior-year quarter, and the operating result (EBIT) rose much more steeply.
