1.       March 16, 2006 German Press Release - SGL Plans Capital Increase

2.       March 17, 2006 German Press Release - SGL Completes Capital Increase





                                                                       Exhibit 1

Ad hoc notification pursuant to ss. 15 of the German Securities Trading Act
(Wertpapierhandelsgesetz)

SGL Carbon Plans Capital Increase

o        Placement of up to 10% of the registered capital
o        Optimization of the Group's finances - strengthening of balance sheet
         and capital base

Wiesbaden, 16 March 2006. SGL Carbon Group plans to place up to 5,583,529 shares
from a capital increase out of authorized capital.

The Board of Management and the Supervisory Board of SGL Carbon have decided to
increase the registered capital of the Company against contribution in cash
excluding preemptive rights. The shares will be placed through an accelerated
bookbuilding process to German and international institutional investors.
Dresdner Kleinwort Wasserstein is acting as sole bookrunner for the transaction.
The issue price and the placement volume of the shares will be published in a
separate ad-hoc announcement.

The proceeds out of this transaction will optimize the Group's finances and
strengthen the balance sheet and the capital base and thus lead to an increased
financial flexibility of the Company. SGL Carbon recently gave guidance for the
2006 financial result of approx. -(euro)55 million. The capital increase will
lead to a further improvement of the financial result of about (euro)5 million
on an annualized basis and therefore from today's point of view not dilute the
earnings per share for the fiscal year. The further reduction of debt through
the proceeds of this transaction should also have a positive influence on the
ratings of the Company and its bond. This increases the probability that SGL
Carbon will be able to further optimize the Group's finances by calling the
outstanding high yield bond with a volume of (euro)270 million and a coupon of
8.5% from 2008 onwards.

This announcement is not an offer of securities for sale in the USA. Securities
may not be offered or sold in the United States without registration with the
U.S. Securities and Exchange Commission if no exemption from registration has
been issued. The issuer does not plan to register the securities for sale to the
public in the United States.
