Munich (euro adhoc) - August 2, 2007 - Wacker Chemie AG again
significantly boosted year-on-year sales and earnings in Q2 2007.
Supported by solid global economic growth, the Munich-based chemical
company greatly expanded its manufacturing output and sales volumes.
The negative impact of further U.S. dollar weakening and higher raw
material and energy costs was more than offset by volume gains. Q2
Group sales accordingly rose 15 percent to EUR959.0 million (Q2 2006:
EUR830.4m).

Earnings again grew more strongly than sales, thanks primarily to
scale effects from higher manufacturing volumes,
productivity-boosting measures, and higher prices in some market
segments. From April to June 2007, the Group generated earnings
before interest, tax, depreciation and amortization (EBITDA) of
EUR260.8 million (Q2 2006: EUR195.7m) - up 33 percent compared to the
prior-year period. The EBITDA margin thus grew to 27.2 percent (Q2
2006: 23.6 percent). The Group´s semiconductor segment, Siltronic,
contributed the largest share to this strong earnings gain. Siltronic
improved its EBITDA by EUR49.8 million year-on-year, thereby
increasing its earnings by nearly 70 percent. WACKER POLYSILICON,
too, significantly enhanced its EBITDA, which rose 51 percent
year-on-year. WACKER POLYMERS profited from continued
construction-sector strength and boosted its EBITDA by 17 percent
year-on-year. However, WACKER SILICONES and WACKER FINE CHEMICALS
only marginally improved their year-on-year figures. The Group´s Q2
2007 earnings before interest and tax (EBIT) surged to EUR178.2
million (Q2 2006: EUR111.8m), with net income climbing 95 percent
year-on-year to EUR130.0 million (Q2 2006: EUR66.5m). Earnings per
share for the period under review are EUR2.62 (Q2 2006: EUR1.35). The
Munich-based company reiterated its full-year 2007 sales and earnings
forecast. Based on current exchange rates, the Group continues to
expect sales revenue grow of over 10 percent, accompanied by a rising
year-on-year EBITDA margin.

"Strong customer demand is the prime driver of our continued dynamic
growth and we are responding to this demand via strategic
production-capacity expansion projects," said CEO Peter-Alexander
Wacker. "Despite additional burdens from raw material and currency
markets, we have significantly surpassed last year´s earnings again.
This underscores our operational strength once more."

In regional terms, Asia and Europe continued to be WACKER´s most
important sales markets in Q2 2007. Central and eastern Europe, as
well as China, showed particularly strong development. WACKER´s Q2
sales in Asia grew 46 percent to EUR328.7 million (Q2 2006:
EUR225.5m). In the period under review, Europe (excluding Germany)
contributed EUR271.5 million (Q2 2006: EUR248.5m) to Group sales - a
year-on-year increase of 9 percent. The Americas and Germany were
virtually equal with Q2 2007 sales of EUR160.9 million (Q2 2006:
EUR165.7m) and EUR168.4 million (Q2 2006: EUR163.8m), respectively.
In the Americas, dollar-related negative currency effects and the
generally slower rate of economic growth had an impact. Accordingly,
prior-year results were not quite reached there. In contrast, Germany
achieved year-on-year sales growth of 3 percent. In the rest of the
world, the Group posted April-to-June sales of EUR29.5 million (Q2
2006: EUR26.9m) - beating the prior-year figure by 10 percent.

The Group´s Q2 2007 net cash flow reached EUR122.1 million (Q2 2006:
EUR15.0m). Thus, net cash flow (i.e. the difference between cash
inflow from operating activities and outflow due to investment
activities) rose by a factor of eight compared to the prior-year
period. The chief factors fueling this jump were robust business
performance and, particularly, additional prepayments from customers
for future polysilicon shipments.

In Q2 2007, investments in intangible assets, property, plant,
equipment, and financial assets amounted to EUR180.7 million (Q2
2006: EUR96.1m) - an 88 percent increase over Q2 2006. The Group
focused investment on creating and expanding production capacities at
its divisions. In Zhangjiagang (China), a WACKER SILICONES production
complex for pyrogenic silica (HDK®) is under construction, and the
division is expanding its downstream silicone facilities there, too.
WACKER POLYMERS is building a new dryer for dispersible polymer
powders in Burghausen (Germany). At the same location, WACKER
POLYSILICON´s Poly 6 and Poly 7 expansion phases will boost
polysilicon capacity. Siltronic is increasing 300 mm wafer capacity
at Burghausen and constructing a new 300 mm wafer line in Singapore.

WACKER had 14,892 employees worldwide on June 30, 2007, slightly more
than in the previous quarter (March 31, 2007: 14,788). 11,513 were
employed in Germany (March 31, 2007: 11,447) and 3,379 at
non-domestic sites (March 31, 2007: 3,341).

Business Divisions WACKER SILICONES reported total Q2 2007 sales of
EUR353.6 million, beating the prior-year period by some 8 percent (Q2
2006: EUR327.3m). Growth was chiefly driven by stronger sales
volumes. The price increases achieved in certain sectors also had a
positive effect. Currency shifts, though, weighed on sales and
earnings. April-to-June EBITDA rose 1 percent from the year-ago
period to EUR68.0 million (Q2 2006: EUR67.0m). Although the division
saw methanol´s market price drop slightly in Q2, raw-material costs
were generally above last year´s level, especially in the case of
silicon metal.

WACKER POLYMERS continued to enjoy the construction sector´s global
buoyancy during the quarter under review. Sales totaled to EUR167.7
million (Q2 2006: EUR147.4m) - a year-on-year increase of about 14
percent. Dispersible polymer powders were the main growth driver,
with production capacity gains boosting sales volumes. The division
increased its EBITDA to EUR34.5 million in Q2 2007, a rise of some 17
percent (Q2 2006: EUR29.4m). Strong earnings were mainly fueled by
volume growth and higher revenues for dispersible polymer powders.
The division had increased its prices for these powders at the
beginning of 2007. On the negative side, earnings were impacted by
currency shifts and higher raw-material costs.

In Q2 2007, WACKER FINE CHEMICALS posted total sales of EUR27.6
million, matching the prior-year level (Q2 2006: EUR28.0m). For
standard products and customized fine chemicals, sales declined. But
the drop was virtually offset by vibrant demand for bioengineered
cysteine. At EUR3.8 million, the division´s April-to-June EBITDA was
above the year-earlier quarter (Q2 2006: EUR3.1m). The improvement
reflects the positive impact of current restructuring measures for
customized fine chemicals.

At WACKER POLYSILICON, total Q2 sales rose 26 percent to EUR97.9
million (Q2 2006: EUR77.9m). Mainly due to higher prices, the
increase also stemmed from volume gains enabled by the Poly 4
polysilicon production plant (commissioned in late 2006).
April-to-June EBITDA climbed 51 percent year on year, reaching
EUR34.8 million (Q2 2006: EUR23.0m). The earnings surge was boosted
by higher polysilicon prices and sales volumes.

Siltronic generated total Q2 2007 sales of EUR370.9 million (Q2 2006:
EUR300.3m) - almost 24 percent above the year-earlier quarter. Key
factors here were substantial volume gains, especially in the 300 mm
wafer segment, and higher average prices for all wafer diameters.
These effects more than compensated for negative currency shifts.
Siltronic´s April-to-June EBITDA soared to EUR122.8 million (Q2 2006:
EUR73.0m). Fueled primarily by volume and price improvements,
earnings were over 68 percent up on the year-ago period.

Outlook In view of the global economy´s current prospects and the
Group´s own appraisal of demand trends, WACKER sees business
remaining robust over the coming six months. WACKER does not,
however, expect second-half results to match the first half-year´s,
due to several scheduled plant shutdowns and declining demand for 200
mm wafers. Based on current exchange rates, the Group continues to
expect full-year sales revenue growth of over 10 percent, accompanied
by a rising year-on-year EBITDA margin.
