SGL Carbon: First Half of 2005

o    Q2/2005 sales up by 17% and EBIT by 57% over Q1/2005

o    Disproportionate  29% improvement in EBIT to (euro)53.8 million in H1/2005,
     with a positive after-tax result of (euro)14.5 million

o    AUDI cooperation agreement goes into effect in Q3/2005

o    Ongoing favorable developments anticipated in Q3/2005

Wiesbaden, August 09, 2005. SGL Carbon was able to boost consolidated sales due
to the strong development of demand in all three business areas by 14.0% from
(euro)453.0 million in H1/2004 to (euro)516.4 million in H1/2005. Adjusted for
foreign currency changes, sales increased by 15.9%. EBIT increased by a
disproportionately higher rate than sales from comparable (euro)41.8 million the
previous year to (euro)53.8 million. This corresponds to a 28.7% increase
despite a first-time charge due to share-based remuneration of approximately
(euro)4 million. The principal causes for the growth in earnings were the
ongoing favorable developments in Carbon and Graphite, the earnings turnaround
in Process Technology, the breakeven result achieved by SGL Technologies in Q2,
and cost savings of approximately (euro)10 million in H1/2005.

Net financing costs
First half-year net financing costs improved from (euro)-31.4 million in 2004 to
(euro)-27.8 million in 2005. The net interest expense decreased during the first
half of the year by (euro)0.8 million to (euro)14.6 million over the same period
of the previous year due to the lower level of net debt. In addition, non-cash
interest expenses in connection with the antitrust proceedings declined from
(euro)3.4 million in the first half of 2004 to (euro)2.6 million in H1/2005.

Profit before and after tax
Profit before income taxes amounted to (euro)26.0 million, compared with
(euro)10.4 million in H1/2004. With a tax rate of approximately 44%,
consolidated net profit in H1/2005 doubled from (euro)7.0 million the previous
year to (euro)14.5 million. Taking into consideration the loss from the Surface
Protection business, profit after tax rose from (euro)0.3 million in the first
half of 2004 to (euro)14.5 million during the same period of 2005. Earnings per
share thus amounted to (euro)0.25, compared with the reported figure of
(euro)-0.06 and a comparable figure of (euro)0.01 in H1/2004.

Statement of Changes in Consolidated Equity
With equity up by (euro)29 million from (euro)282 million on December 31, 2004
to (euro)311 million on June 30, 2005, the equity ratio improved from 21.4% to
24.3%. Excluding assets and liabilities related to the Corrosion Protection
business in the balance sheet as of December 31, 2004, the equity ratio
increased from 22.5% to 24.3%. When the (euro)50 million convertible bond issue,
which becomes due in September 2005, is deducted from total assets as of the end
of June 2005, a 25.3% pro forma equity ratio results.

Corporate Costs
Corporate costs rose from (euro)-9.9 million in the first half of 2004 to
(euro)-13.8 million in the first half of 2005. This was primarily attributable
to expenses in connection with the implementation of the Sarbanes-Oxley Act as
well as the first time inclusion of share-based remuneration components under
the provisions of IFRS 2 beginning on January 1, 2005, which was not undertaken
in the previous year.

Employees
The number of employees in the Group remained virtually unchanged at 5,097
compared with a total of 5,091 at the end of March 2005, thereby remaining below
the level of 5,109 at the end of December 2004.

Segment Reporting

Carbon and Graphite (CG)
Sales increased by 14.3% to (euro)311.1 million in the first half of 2005.
Adjusted for foreign currency changes, the growth was 16.9%. Due to the
continuing high demand for graphite electrodes and the high capacity utilization
at all the plants as well as to price increases and ongoing cost reduction
measures, EBIT amounted to (euro)60.3 million during the reporting period, up by
32.8% over the previous year's figure of (euro)45.4 million. The return on sales
improved to over 19%, compared with just under 17% in the first half of 2004
(EBIT margin in Q2/2005: 20.0%; Q1/2005: 18.7%). The average price for graphite
electrodes increased by 12% in USD terms and by 4% in EUR terms versus H1/2004.
Total shipments amounted to 110,000 metric tons in the first half of 2005, 10%
higher than in the first half of the previous year. As expected, raw material
and energy costs increased by nearly 10%. Due to seasonally lower volumes, we
are projecting the Q3/2005 EBIT slightly lower than in Q2/2005 ((euro)33.6
million), but in excess of the previous year's Q3 figure of (euro)25.5 million.


                                      2/6



Specialties (S)
Due to the integration of Process Technology (PT) into the Graphite Specialties
Business Area (GS), we have renamed this area of business "Specialties" (S).

Thanks to a very good development of the U.S. business and PT's planned project
launch in Q2/2005, sales increased by 7.2% to (euro)123.6 million versus
H1/2004; growth of 7.7% was posted after adjusting for foreign currency changes.
The rise in sales was modest for GS and substantial for PT. Whereas EBIT of GS
was still below the strong previous year's figure, PT already recorded an
improved result in the first half-year compared with the year earlier period.
EBIT for the overall Specialties Business Area in the first half-year amounted
to (euro)7.9 million, which due to the weak Q1/2005 was still (euro)2.3 million
below the figure for H1/2004. However, with EBIT of (euro)6.6 million, the
Q2/2005 result was already one-third higher than in Q2/2004, with PT
contributing to that growth. From Q3/2005 onwards, the ongoing favorable sales
trend will be further reflected in the EBIT of S, which will result in a
significant double-digit improvement over Q3/2004.


                                      3/6



SGL Technologies (SGL T)
Due to strong demand for Fibers, Composites and Brakes, sales rose by 24.8% to
(euro)80.5 million. After adjusting for foreign currency changes, growth
amounted to 26.2%. EBIT totaled (euro)-0.6 million in the first half of 2005,
compared with (euro)-3.9 million in the first half of the previous year, thereby
reaching breakeven for the first time in Q2/2005. This satisfying development
should continue in Q3/2005, with the increase in sales remaining below the
growth in H1/2005 due to the high comparable figure in Q3/2004 but still
continuing to exceed 10%.

Since the June 7, 2005 announcement of SGL Carbon entering a cooperation
agreement with AUDI for the development of the carbon-ceramic brake disc, the
appropriate bodies have since granted the necessary approvals and the agreement
has received its notarial certification. With the official cooperation agreement
coming into force on July 28, 2005, SGL Carbon will in Q3/2005 receive a low
double-digit million amount payment as compensation for product and process
development services already rendered and still to be provided. After offsetting
these development costs from the received payment, a one-time medium single
digit million amount is expected as positive earnings effect on EBIT in Q3.

Outlook
Due to the typical seasonality, SGL Carbon expects slightly weaker sales and
EBIT in Q3/2005 versus Q2/2005. Compared with Q3/2004, however, marked growth of
approximately 10% is anticipated for sales and a further disproportionate
improvement of up to 50% for EBIT. For the year as a whole, the Company is
forecasting an increase in consolidated sales of between 5% and 10%, a
disproportionate growth in EBIT, and a positive after-tax result. The USD
currency risk is hedged for fiscal year 2005 due to existing hedging
transactions. Net financial debt should be less than (euro)300 million at
year-end 2005 (2004 yearend: (euro)321 million) due to the significant positive
free cash flow expected until the end of this year.

Remark
------
Effective January 6, 2005, SGL Carbon concluded the sale of its investment in
SGL ACOTEC GmbH, which included SGL's Surface Protection business. The effects
resulting from this transaction were already recognized in the annual financial
statements for 2004. The Process Technology (PT) business remaining in the Group
was integrated within the Specialties (S) Business Area. Only the results of
continuing operations are presented in this semi-annual report.


                                      5/6



According to IFRS 2, since January 1, 2005, share-based payments, such as stock
option plans and share bonus programs for employees and members of senior
management are included under staff costs. Based on current calculation, this
change will burden the results of the segments and corporate costs by a total of
approximately (euro)2 million each quarter in 2005.

As we already discussed at the year-end press conference in March, the
restructuring measures have now largely been completed. Therefore, profit from
operations (EBIT) no longer includes a separate presentation of restructuring
expenses.




Important Notice:
This document contains statements on future developments that are based on
currently available information and that involve risks and uncertainties that
could lead to actual results deviating from these forward-looking statements.
These risks and uncertainties include, for example, unforeseeable changes in
political, economic and business conditions, particularly in the area of
electrosteel production, the competitive situation, interest rate and currency
developments, technological developments and other risks and unanticipated
circumstances. We see other risks in price developments, unexpected developments
relating to acquired and consolidated companies, ongoing restructuring measures
and unforeseeable occurrences in conjunction with the reviews to be performed by
the European antitrust authorities. SGL Carbon does not intend to update these
forward-looking statements.

Effective January 6, 2005, SGL Carbon concluded the sale of its investment in
SGL ACOTEC GmbH, which included SGL's Surface Protection business. The effects
resulting from this transaction were already recognized in the annual financial
statements for 2004. The Process Technology (PT) business remaining in the Group
was integrated within the Specialties (S) Business Area. Only the results of
continuing operations are presented in this semi-annual report.

According to IFRS 2, since January 1, 2005, share-based payments, such as stock
option plans and share bonus programs for employees and members of senior
management are included under staff costs. Based on current calculation, this
change will burden the results of the segments and corporate costs by a total of
approximately (euro)2 million each quarter in 2005.

As we already discussed at the year-end press conference in March, the
restructuring measures have now largely been completed. Therefore, profit from
operations (EBIT) no longer includes a separate presentation of restructuring
expenses.

1.       Comparable EBIT for the H1/2004 is calculated as follows: reported EBIT
         after restructuring expenses amounted to (euro)25.4 million in H1/2004.
         Taking into consideration the (euro)11.3 million operating loss from
         the divested Surface Protection business, the discontinuation of the
         (euro)2.6 million scheduled goodwill amortization in accordance with
         IFRS 3, and the reclassification of the interest on the North American
         pension provisions of (euro)2.5 million, which are now unified and
         shown in the net financing costs, the comparable EBIT of (euro)41.8
         million results.

2.       In H1/2005 approximately 56.9 million shares were outstanding on
         average.


Due to the strong development of demand in all three business areas,
consolidated sales were boosted by 14.0% from (euro)453.0 million in H1/2004 to
(euro)516.4 million in H1/2005. Adjusted for foreign currency changes, sales
increased by 15.9%. EBIT increased by a disproportionately higher rate than
sales from comparable (euro)41.8 million the previous year to (euro)53.8
million. This corresponds to a 28.7% increase despite a first-time charge due to
share-based remuneration of approximately (euro)4 million. The principal causes
for the growth in earnings were the ongoing favorable developments in Carbon and
Graphite, the earnings turnaround in Process Technology, the breakeven result
achieved by SGL Technologies in Q2, and cost savings of approximately (euro)10
million in H1/2005.

First half-year net financing costs improved from (euro)-31.4 million in 2004 to
(euro)-27.8 million in 2005. The net interest expense decreased during the first
half of the year by (euro)0.8 million to (euro)14.6 million over the same period
of the previous year due to the lower level of net debt. In addition, non-cash
interest expenses in connection with the antitrust proceedings declined from
(euro)3.4 million in the first half of 2004 to (euro)2.6 million in H1/2005.


Profit before and after tax
Profit before income taxes amounted to (euro)26.0 million, compared with
(euro)10.4 million in H1/2004. With a tax rate of approximately 44%,
consolidated net profit in H1/2005 doubled from (euro)7.0 million the previous
year to (euro)14.5 million. Taking into consideration the loss from the Surface
Protection business, profit after tax rose from (euro)0.3 million in the first
half of 2004 to (euro)14.5 million during the same period of 2005. Earnings per
share thus amounted to (euro)0.25, compared with the reported figure of
(euro)-0.06 and a comparable figure of (euro)0.01 in H1/2004.

(1) Including convertible bonds totaling (euro)50 million as of June 30, 2005


Primarily due to the sale of the Surface Protection business on January 6, 2005,
total assets declined by (euro)37 million to (euro)1,278 million as of June 30,
2005. In the first half of 2005 a scheduled payment of (euro)15 million was made
out of the restricted cash account for antitrust payments to the U.S. antitrust
authorities.

The increase in working capital by (euro)59 million over the year-end 2004
resulted from higher than expected business activity especially at CG and SGL T.
Despite the typically high seasonal level at mid-year, we were nevertheless able
to reduce the average days working capital from 149 as of June 30, 2004, to 139
as of June 30, 2005.

With equity up by (euro)29 million from (euro)282 million on December 31, 2004
to (euro)311 million on June 30, 2005, the equity ratio improved from 21.4% to
24.3%. Excluding assets and liabilities related to the Corrosion Protection
business in the balance sheet as of December 31, 2004, the equity ratio
increased from 22.5% to 24.3%. When the (euro)50 million convertible bond issue,
which becomes due in September 2005, is deducted from total assets as of the end
of June 2005, a 25.3% pro forma equity ratio results.

Net financial debt as of June 30, 2005, increased compared to the year-end 2004
level due to the (euro)20 million lower level of unrestricted cash and cash
equivalents. Due to exchange rate effects of (euro)10 million, net debt at
comparable exchange rates increased by only (euro)11 million.

Gearing was 1.1 as of June 30, 2005. Although unchanged from December 31, 2004,
it slightly improved over the 1.2 figure as of March 31, 2005.

(1) adjusted by currency effects









SGL Carbon attained a positive operating cash flow of (euro)43.0 million in the
first half of 2005, compared with (euro)45.3 million in the same period of the
previous year. Higher profit contributions from operating activities contrasted
with a temporary build-up of working capital, which was largely attributable to
servicing higher than expected demand. Other operating cash uses increased to
(euro)37.7 million from (euro)22.8 million in the first half of 2004. The main
reasons for this are the semi-annual interest payment for the corporate bond,
which had been paid for the first time in August 2004 as well as the bonus
payment in 2005, since the Board of Management and 156 members of senior
management waived their bonuses in 2004 as part of the refinancing and capital
increase efforts of the company. As a result, net cash provided by operating
activities before antitrust payments amounted to (euro)5.3 million in the first
half of 2005, compared with (euro)22.5 million in the same period the previous
year.

Payments made in connection with antitrust proceedings comprised the scheduled
payments to the North American antitrust authorities of (euro)15.1 million,
which were paid out of the restricted cash account for antitrust payments.

Capital expenditure of (euro)17.4 million exceeded the previous year's figure of
(euro)15.5 million, and was approximately (euro)17 million below depreciation of
(euro)34.8 million during the reporting period, compared with (euro)29.2 million
in H1/2004. Due to the above-mentioned development of working capital as well as
the higher interest and bonus payments, free cash flow amounted to (euro)-12.1
million in the first half of 2005, compared with (euro)3.4 million in the first
half of 2004.

Sales increased by 14.3% to (euro)311.1 million in the first half of 2005.
Adjusted for foreign currency changes, the growth was 16.9%. Due to the
continuing high demand for graphite electrodes and the high capacity utilization
at all the plants as well as to price increases and ongoing cost reduction
measures, EBIT amounted to (euro)60.3 million during the reporting period, up by
32.8% over the previous year's figure of (euro)45.4 million. The return on sales
improved to over 19%, compared with just under 17% in the first half of 2004
(EBIT margin in Q2/2005: 20.0%; Q1/2005: 18.7%). The average price for graphite
electrodes increased by 12% in USD terms and by 4% in EUR terms versus H1/2004.
Total shipments amounted to 110,000 metric tons in the first half of 2005, 10%
higher than in the first half of the previous year. As expected, raw material
and energy costs increased by nearly 10%. Due to seasonally lower volumes, we
are projecting the Q3/2005 EBIT slightly lower than in Q2/2005 ((euro)33.6
million), but in excess of the previous year's Q3 figure of (euro)25.5 million.

Due to the integration of Process Technology (PT) into the Graphite Specialties
Business Area (GS), we have renamed this area of business "Specialties" (S).

Thanks to a very good development of the U.S. business and PT's planned project
launch in Q2/2005, sales increased by 7.2% to (euro)123.6 million versus
H1/2004; growth of 7.7% was posted after adjusting for foreign currency changes.
The rise in sales was modest for GS and substantial for PT. Whereas EBIT of GS
was still below the strong previous year's figure, PT already recorded an
improved result in the first half-year compared with the year earlier period.

EBIT for the overall Specialties Business Area in the first half-year amounted
to (euro)7.9 million, which due to the weak Q1/2005 was still (euro)2.3 million
below the figure for H1/2004. However, with EBIT of (euro)6.6 million, the
Q2/2005 result was already one-third higher than in Q2/2004, with PT
contributing to that growth. From Q3/2005 onwards, the ongoing favorable sales
trend will be further reflected in the EBIT of S, which will result in a
significant double-digit improvement over Q3/2004.

Due to strong demand for Fibers, Composites and Brakes, sales rose by 24.8% to
(euro)80.5 million. After adjusting for foreign currency changes, growth
amounted to 26.2%. EBIT totaled (euro)-0.6 million in the first half of 2005,
compared with (euro)-3.9 million in the first half of the previous year, thereby
reaching breakeven for the first time in Q2/2005. This satisfying development
should continue in Q3/2005, with the increase in sales remaining below the
growth in H1/2005 due to the high comparable figure in Q3/2004 but still
continuing to exceed 10%.

Since the June 7, 2005 announcement of SGL Carbon entering a cooperation
agreement with AUDI for the development of the carbon-ceramic brake disc, the
appropriate bodies have since granted the necessary approvals and the agreement
has received its notarial certification. With the official cooperation agreement
coming into force on July 28, 2005, SGL Carbon will in Q3/2005 receive a low
double-digit million amount payment as compensation for product and process
development services already rendered and still to be provided. After offsetting
these development costs from the received payment, a one-time medium
single-digit million amount is expected as positive earnings effect on EBIT in
Q3.

Corporate costs rose from (euro)-9.9 million in the first half of 2004 to
(euro)-13.8 million in the first half of 2005. This was primarily attributable
to expenses in connection with the implementation of the Sarbanes-Oxley Act as
well as the first time inclusion of share-based remuneration components under
the provisions of IFRS 2 beginning on January 1, 2005, which was not under-taken
in the previous year.



Employees

The number of employees in the Group remained virtually unchanged at 5,097
compared with a total of 5,091 at the end of March 2005, thereby remaining below
the level of 5,109 at the end of December 2004.



Outlook

Due to the typical seasonality, SGL Carbon expects slightly weaker sales and
EBIT in Q3/2005 versus Q2/2005. Compared with Q3/2004, however, marked growth of
approximately 10% is anticipated for sales and a further disproportionate
improvement of up to 50% for EBIT. For the year as a whole, the Company is
forecasting an increase in consolidated sales of between 5% and 10%, a
disproportionate growth in EBIT, and a positive after-tax result. The USD
currency risk is hedged for fiscal year 2005 due to existing hedging
transactions. Net financial debt should be less than (euro)300 million at
year-end 2005 (2004 year-end: (euro)321 million) due to the significant positive
free cash flow expected until the end of this year.
