For this reason I am standing down as CEO of Thyssenkrupp Industrial Solutions – irrespective of legal issues and the findings of the on-going internal investigation. I would like to wish all employees the very best for the future and every success in the continuing implementation of the transformation,” said Wegmann in a statement.
