SGL Carbon SE said late Monday that Susanne Klatten would step down as chairwoman of the supervisory board for personal reasons.
The Germany-based company, which makes carbon products for the auto industry, semiconductor manufacturers and others, said Ms. Klatten would leave the board at the end of the annual general meeting on May 9.
Ms. Klatten is the main shareholder of SGL Carbon, owning a 28.50% stake in the company, according to FactSet.
"Her commitment as the main shareholder of SGL Carbon remains unaffected by her personal decision to resign from the supervisory board," the company said.
