context_page_description: SGL Carbon SE is a European company based in Germany. It is one of the world's leading manufacturers of products from carbon. The company portfolio ranges from carbon and graphite materials and solutions to carbon fibers and composites.
  With 29 production sites around the globe, and a service network in over 100 countries, SGL Carbon is a globally operating company. The company headquarters is Wiesbaden, Germany.
  The SGL share had been included in the German MDAX since 1995 and fell in the smaller SDAX in September 2014. In March 2020, the Deutsche Boerse announced that SGL Carbon will no longer be a constituent of the SDAX due to the low free float market capitalization. In 2019 the company generated sales revenue of €1,087 million and employed 5,100 staff worldwide.
context_section_description: SGL Carbon AG originated in 1992 from a merger between SIGRI GmbH (Germany) and Great Lakes Carbon (USA) to share a company according to German law. (Some information about the history of Great Lakes Carbon can be found on the Wikipedia page for its founder George Skakel).
  SIGRI traced back to Gebr. Siemens & Co (Gesco), founded in Berlin as a subsidiary of Siemens AG in 1878. The company originally produced carbon. In 1920, the company set up a plant in Meitingen (Bavaria) and in 1928 merged with Planiawerke AG für Kohlefabrikation in Ratibor (Upper Silesia) to form the new Siemens Planiawerke AG für Kohlefabrikate. After the Second World War, the Meitingen plant of the Siemens Planiawerke AG für Kohlefabrikate merged with Chemische Fabrik Griesheim to form Siemens Plania Chemisches Werk Griesheim, the majority of which was acquired by Hoechst AG in 1953. In 1967, as a result of the merger with electrode manufacturing at Hoechst AG, Siemens Planiawerke AG für Kohlefabrikate also became a majority holding of the chemical company. There it was amalgamated with the Siemens Plania Chemisches Werk Griesheim and other enterprises of Hoechst AG. In 1985 it was renamed SIGRI GmbH and finally Hoechst AG acquired total ownership in 1989.
  After the merger with Great Lakes Carbon, Hoechst AG retained a 50 percent stake in the new company. The remaining participation was sold in 1996 as part of restructuring of the Hoechst Group. Since then SGL Carbon AG is publicly traded.
  In the course of the strategic realignment in 2017, SGL Carbon sold its former core business with graphite electrodes and the business with cathodes, furnace linings and carbon electrodes. At the beginning of 2018, the company sold its shares in the joint venture SGL-Kümpers to the former joint venture partner Kümpers GmbH.
  Also in 2018, SGL Carbon acquired the shares in the joint venture Benteler-SGL from Benteler AG and announced the gradual acquisition of BMW Group's shares in the joint venture SGL Automotive Carbon Fibers (ACF).
