German press release dated September 29, 2005 on SGL Carbon Redeems Convertible Bond and Reduces US$ Credit EXHIBIT 1 SGL Carbon's Ratings Upgraded by Standard & Poor's Wiesbaden, August 12, 2005. The corporate, credit, and bond ratings for SGL Carbon were upgraded by the rating agency Standard & Poor's yesterday. The credit rating for SGL Carbon AG was raised from "B" to "B+" with the outlook "stable". S&P simultaneously increased the rating of the bond that was issued by SGL Carbon Luxembourg S.A. from "CCC+" to "B-". The credit rating for SGL Carbon LLC (USA) was furthermore raised from "B" to "B+". These upgrades will have a favorable impact on potential future financial arrangements undertaken by SGL Carbon. Standard & Poor's had placed SGL Carbon on its watch list for a possible upgrade following the announcement of the cooperation agreement with Audi on June 7, 2005. The upgrade then followed the analysis of the half-year interim report, which was disclosed on August 9. Standard & Poor's bases its higher ratings in particular on the substantial increase in profit from operations and the improvements in the financial figures over the past six months, as well as the Company's healthy business outlook and the high level of capacity utilization of the core business with graphite electrodes, the sale of the loss-generating Surface Protection operations, and the recent reduction in the second EU fine.

The South African nuclear energy technology company "Pebble Bed Modular Reactor" PBMR (Pty) Ltd. announced today its cooperation with SGL Carbon as a supplier of graphite. A conference will be held this week in Pretoria with focus on the current status of the development of the pebble bed modular reactor technology. PBMR is owned by a consortium comprising the largest South African energy supplier, Eskom, as well as the state-owned development finance institution Industrial Development Corporation of South Africa (IDC), and British Nuclear Fuels (BNFL). PBMR has the ambition to construct commercially operating pebble bed modular reactors for electric power generation in South Africa beginning in 2013. As an alternative to non-renewable fossil fuel resources, PBMR technology is to be utilized in the near future as a low-cost, CO2-free form of energy production. PBMR selected SGL Carbon as a strategic supplier because of the latter's expertise in the production and development of graphite in the highest quality. The two companies have been working together for a number of years on the development of materials for use in PBMR technology. The planned construction of a demonstration reactor in South Africa beginning in 2007 could translate into sales of (euro) 35 to (euro) 40 million during the period 2006 to 2008 for the Specialties Business Unit of SGL Carbon.

SGL Carbon repaid to investors the outstanding 37 percent of the convertible bond that matured today. The bond had originally been issued in September 2000. Between the end of February and early April 2004, SGL Carbon redeemed 63 percent of the convertible bond on the basis of a voluntary redemption offer. Within the framework of the refinancing measures at the beginning of 2004, the Company had deposited the funds required to redeem the convertible bond in a cash escrow account. SGL Carbon was additionally able to reduce its US credit facility from US$ 112 million to US$ 80 million in early September. The Company's main banks acquired this credit from the over 70 U.S. financial investors with whom it had previously been placed. This step further underscores the progress the Company has been making in the reduction of its debt. Both measures serve to strengthen the equity ratio of SGL Carbon in the third quarter (assuming unchanged exchange rates from the date for the first half-year's financial figures - June 30, 2005).
