HIGHLIGHTS

• ≥ Revenue: Slightly regressive with –7 %
• ≥ Cost structure: Adapted to the market environment
• ≥ EBIT: Improved by € +0.5 m
• ≥ Order backlog: Increased by 6 % to € 34.9 m
• ≥ Framework agreements for mid-term financing secured

SW Umwelttechnik continues to face a volatile market environment. While our production output in Hungary decreased by 27 %, we were able to increase this in Romania by 10 % and in Austria even by 30 %. The increased focus on projects financed by the EU for the protection of the environment and the development of transport infrastructure has proven itself yet again. We will make more use of the investment funds available to us in order to continue along this route. The order backlog has increased by 6 % compared to the previous year and now amounts to € 34.9 m, whereby the water conservation segment increased disproportionately by 28 %.

Compared to the previous year we reduced our personnel by 13 % to 537 employees and have thus adapted to the reduced revenue of - 7 %. Due to the implemented measures we were able to save around € 5.6 m (of which € 2.8 m in personnel costs) during the first half year 2011 compared to the half year 2008 before the crisis. This reflects savings on fixed costs of 30 %.

We were able to finalise framework agreements with our financing banks as reported in July 2011 in which the repayment patterns of our investment loans have been adapted to the changed economic environment.

FOREWORD BY THE MANA GEMENT BOARD

Dear ladies and gentlemen, dear shareholders, business partners and employees,

We have been able to adapt to the ongoing difficult market environment in Hungary and Romania by saving on fixed costs and were able to improve our operating result compared to the previous year even though our revenue decreased. Our number of staff was reduced by a further 13 % compared to the previous year while gross yield, an indicator of price development, was improved by two percentage points.

We succeeded in introducing new water conservation products in Austria and we have also seen a significant increase in investments from our industrial and trade clients. Due to this the market downturn in the municipalities could be overcompensated. We were thus able to increase our revenue disproportionately to the market development by 27 % compared to the previous year.

In Hungary we have been concentrating on stabilising the price level after having clearly succeeded in reaching the market leadership in the previous year. Therefore our revenue decreased by – 25 %, so more than the total market did. However, our operating result increased due to this procedure.

We have been witnessing a stabilisation of the market in the industry and trade sector while the municipal sector remains below our expectations due to delayed commissioning.

We were able to increase our production output in Romania by focusing on the water conservation sector and thus EU subsidised projects. By installing a complete sewer production line in Bucharest, which started operations in the middle of the year, we were able to significantly decrease freight costs and could thus improve our operating result. As expected investments from the industry and trade sector continue to decrease and we only anticipate a recovery in this sector from 2013 onwards. In contrast, local, EUsubsidised projects are on the rise and we expect further growth in this sector.

The order backlog of € 34.9 m was increased by 6 % compared to the previous year whereby the increase in the water conservation sector of 28 % overcompensated the decrease of commissioning from industry and trade clients of

• 14 %. This development allows for a positive inference of the second half year 2011 and again confirms our decision to focus on the water conservation sector with its EU subsidised projects.

Our expansion programme from 2005 to 2008 was mainly financed through bank loans. The repayment pattern however did not correspond to the current economic climate and in July 2011 we negotiated framework agreements with our financing banks that include a deferral of repayments until June 30th 2012 and an adjustment of the long-term repayment patterns to the economic environment.

Our outlook for the second half year remains cautious, yet positive. Low visibility in terms of the economic development in our core markets Hungary and Romania mean we can only make short-term predictions. We expect an improvement and speedup of commissioning for municipal projects in Hungary. In Romania we will be able to see a noticeable reduction of freight costs due to the restructuring of production. The order backlog in Austria and Romania suggest an increased workload for the following months. Therefore we continue to expect an increase in operative earnings for the whole year, based on the implemented cost adjustments and the focus on EU subsidised projects.

OPERATIONAL REVIEW

ECONOMIC CLIMATE

The economic climate that the SW group operates in shows differentiating trends. Austria has shown a clear positive development due to its ideal location between Germany and Central Eastern Europe – in contrast Hungary and especially Romania continue to face a difficult environment. National demand remains very low in both countries, although an increase is expected for 2011.

↗ Austria

Austria is one of the top players within the Euro zone – the key factor for this economic development is the export sector. Austria profits strongly from its trading partner Germany, but capital investments in Austria are also significantly increasing. The GDP prognosis for 2011 is in accordance with this development and amounts to a strong 3.3 % (2010: 2.1 %; 2009: -3.9 %).

↗ Hungary

The exports of the manufacturing sector have now also become a key factor to economic development – however national investments remain very low. A GDP growth of 2.5 % is expected for 2011 (2010: 1.2 %; 2009: - 6.7 %). The government is keen to advance its structural reforms, which is being acknowledged by the rating agencies. The HUF/EUR exchange rate has been very stable in the last quarters with a slender margin of 264 to 270. We expect similarly low volatility for the whole year.

↗ Romania

The gradual recovery of the economy permits a generally positive outlook. Due to the significant economic imbalances in Romania before the crisis, the Romanian private sector is still mainly unable to make any investments and will recover only step-by-step. A slight improvement can be expected because debt financing and the accrual of foreign capital is being accepted with more confidence. A slight growth is expected for the second half year – with a GDP growth of 1.5 % for the whole year (2010: - 1.3 %; 2009: - -7.1 %). Significant economic growth is only expected at the earliest for 2012 as the government has no leeway for higher national spending due to the necessary budget consolidation.

BUSINESS PERFORMANCE AND EARNINGS

The slow improvement of our core markets Hungary and Romania is reflected in our group revenue – it amounts to € 27.8 m for the first half year 2011 and is thus € 2.2 m below that of the previous year (2010: € 30.0 m).

Due to the implemented adjustments of our fixed costs to the current market situation and the increased gross margins, EBIT has improved and now amounts to € - 1.7 m (2010: € - 2.1 m). EBITDA is again in the plus and amounts to € 0.5 m (2010: € 0.6 m). The stable exchange rate trend of HUF and RON, the foreign currencies relevant to SW, has lead to a financial result of € - 0.5 m, which is € 2.3 m better than for the same time period in 2010 (€ - 2.9 m). This also results in a significantly improved result on ordinary activities of € - 2.2 m (2010: € - 5.0 m).

When looking at the second quarter only, the figures of the first half year are clarified. Even though revenue decreased significantly from € 21.7 m in 2010 to € 19.2 m in 2011, our earnings have been improved. Gross margins margins have been further improved by 3 percentage points in the second quarter and EBIT is stable at € 0.8 m compared to the previous year. Result on ordinary activities improved to € - 0.5 m in the second quarter 2010 it still amounted to € - 2.5 m. The relatively stable exchange rate of HUF and RON has also had a positive impact on our financial result.

Revenue by business sectors in € m

ORDER BACKLOG

The order backlog as of June 30th 2011 amounts to € 34.9 m and is therefore 6 % above that of the previous year (2010: € 33.0 m). We are planning on completing 87 % of this in the current year and 13 % in the following year.

In Hungary the order backlog of € 14.5 m (2010: € 15.7 m) is 7 % lower than in 2010, which is mainly due to the decreasing marketing trend in the civil engineering sector. This has only been partly compensated with local EU subsidised projects due to the delayed commissioning of these projects. In Austria the order backlog amounts to € 4.2 m (2010: € 3.7 m) and is thus 15 % above that of the previous year and therefore confirms our positive outlook for the whole year. The order backlog in Romania is also 5 % higher than in the previous year and amounts to € 14.3 m (2010: € 13.5 m).

EMPLOYEES

The number of employees (incl. temporary workers) has been reduced by 16 % compared to the previous year and amounts to an average of 658 for the first half year (2010: 787). Operating efficiency per employee (incl. temporary workers) could thus be increased by 10.5 %.

Total output per employee in EUR `000

Orders in the water conservation sector amount to € 13 m (2010: € 10.2 m) and have thus increased by another 28 % compared to the strong previous year. The infrastructure sector orders amount to € 7.8 m (2010: € 9.1 m), which reflects a decrease of - 14 % and is well below the amount of June 30th 2010. Orders in our project engineering sector amount to € 14.1 m (2010: € 13.7 m), an increase of 3 % compared to the previous year.

119 fixed staff were employed in Austria, so 2 % more than in 2010. In Hungary we employed 264 fixed employees, so 15.9 % less than in 2010. In Romania we had 154 fixed employees in the first half year, which reflects a decrease of 16.8 % compared to the previous year.

SEGMENTAL ANALYSIS

In the first half year 2011, revenue is distributed to the different business segments similarly to the previous year. As the biggest sector, water conservation has a revenue share of 50 %, so € 13.9 m (2010: € 13.5 m). The difficult market environment is noticeable in the infrastructure sector where revenue now amounts to € 9.3 m (2010: € 11.6 m) and a share of 33 % (2010: 39 %). The project engineering sector has decreased slightly and now amounts to € 4.6 m (2010: € 4.9 m).

↗ Austria

When looking at the regional allocation, Austria has improved the best and we were able to increase revenue by 27 %, which reflects a revenue of € 7.1 m. This can be attributed to introducing new product lines and the improvement of the economic environment. Austria now holds a share of total revenue of 26 % (2010: 19 %).

↗ Hungary

In 2010 we were able to reach the leadership in all our market segment. The economic development in 2011 on the one hand and the measures to ensure price stability on the other hand have led to a reduction of revenue of - 25 %, which now amounts to € 12.6 m (2010: € 16.8 m). But, because of the executed measures of adapting the fixed costs to the market environment we were, able to improve our operating result compared to the previous year. The share of total revenue has therefore decreased and now amounts to 45 % (2010: 56 %).

↗ Romania

In Romania we were able to increase production output by 10 %. Due to unit prices however, revenue decreased by 8 % to € 5.9 m (2010: € 6.4 m). Its share of total revenue therefore remains unchanged with 21 %.

Revenue by geographical markets HY 2011

SUMMARY BALANCE SHEE T

Long-term assets are reported at € 77.9 m (2010: € 75.3 m) whereby the increase compared to the previous year can be attributed to the fair value assessment at the end of the year of non-core properties. Current assets amount to € 33.7 m (2010: € 34.2 m) and are thus slightly below that of the previous year. The balance sheet total therefore amounts to € 111.6 and is slightly above that of the previous year (€ 109.5 m).

Equity capital as per June 30th 2011 amounts to € 14.6 m and is thus significantly higher than in the previous year (€ 11.8 m). This also leads to an improved equity capital ratio of 13.1 % (2010: 10.8 %). Financial liabilities now amount to € 78.0 m, which is less than in the previous year (€ 79.9 m).

INVESTMENTS

As in the previous year, we kept our investments on a low level and they thus amount to € 1.0 m in the first half year (2010: € 1.1 m). We invested into production facilities in Austria for our new products and into a restructuring of our production facilities in Bucharest, where we now focus on water conservation products.

OUR SHARE

The stock price of our SW Umwelttechnik share (SWUT) is currently on a slight decrease – with a closing rate on June 30th 2011 of 16.5. The share has been affected by the generally weak development of the financial markets that led to a historic low of € 11 per share in August.

By focusing on Eastern Europe and the water conservation area, we are offering sustainable perspectives for our investors and thus an interesting long-term investment.

OUTLOOK

We are expecting an increased growth in the Euro zone during the second half year. Due to the volatile capital markets and the insecurities in assessing economic development in Central Eastern Europe, visibility remains low.

↗ Austria

The implemented structural adjustments in 2010 are showing their effects. As in the first half year we are expecting a positive development of our company in the second half year as well. Our newly introduced large basins (drinking water reservoirs, biogas facilities, sewer networks), fish ladders (power house construction) and the recon walls (supporting systems for hang walls) have already led to very good results.

↗ Hungary

As market leader, SW Umwelttechnik will continue to follow its strategy in stabilising prices and due to the expected increase in commissioning of EU subsidised projects we are estimating a part recovery of revenue.

↗ Romania

We are expecting a significant improvement of our earnings in the second half year due to the reduction of freight costs and the close proximity to the important regional market in the Bucharest area resulting from our focus on EU subsidised projects and our investments into the water conservation area at our Bucharest site.

Even though we are facing difficult conditions in Hungary and Romania, we are overall expecting a significant improvement of our operative result compared to the previous year.

NOTES TO THE GROUP'S INTERIM FINANCIAL STATEMENTS FOR THE FIRST HALF 2011

The Group's interim financial statements at hand as per 30 June 2011 have been created in accordance with the International Financial Reporting Standards (IFRS) as to be applied in the EU.

The abbreviated interim financial statements do not include – in accordance with IAS 34 – all information and data necessary in the annual financial statements and should thus be read in combination with the SW Umwelttechnik Stoiser & Wolschner AG's annual consolidated financial statements as per 31 December 2010.

SCOPE OF CONSOLIDAT ION

The scope of consolidation remains unchanged compared to the status as per 31 December 2010.

FINANCIAL ACCOUNTING AND VALUATION METHODS

In the interim financial statement per 30.06.2011 expenses for outbound cargo have been included in "Expenses for materials" and amount to € 2,285 k (2010: € 2,086 k). Expenses for outbound cargo had been included heretofore in "Other operating costs". To guarantee comparability, the previous year's figures have been adjusted.

The same accounting and valuation methods as per 31 December 2010 have been applied apart from that.

The following exchange rates have thus been applied:

CURRENCY CONVERSION

The Group's functional currency is the Euro; the functional currencies of the foreign subsidiaries are the respective local currencies.

The annual financial statements of foreign subsidiaries and joint ventures have thus been converted using the modified closing-date-method according to IAS 21 as follows:

≥ Assets and liabilities with the exchange rate of the balance sheet closing date

≥ Revenue and expenditures with the exchange rate of the annual average

≥ Equity entries with the exchange rate of the date of the transaction

FINANCIAL INSTRUMENTS

No financial instruments apart from those disclosed in the annual report 2009 were applied during the reporting period.

BUSINESS TRANSACTIONS AFTER THE BALANCE SHEET DATE

No business transactions occurred after the balance sheet date of the quarter impacting the interim financial report at hand or that have any particular relevance.

OTHER OBLIGATIONS, LITIGATION AND POSSIBLE LIABILITIES
