The majority of Stefan Quandt's wealth derives from a 25.8% stake in the common shares of Bayerische Motoren Werke, the Munich-based automaker. He owns a 0.2% stake directly and the rest through AQTON holding companies, according to BMW's 2018 annual report.
He owns about 87% of publicly traded logistics provider Logwin through closely held investment company, Delton.
The billionaire controls Biologische Heilmittel Heel, a closely held homeopathic medicine company, which had more than 200 million euros in revenue in 2017, according to its website. It's valued using the average enterprise value-to-sales, enterprise value-to-Ebitda and price-to-earnings multiples of two publicly traded peers: Boiron and Nature's Sunshine Products.
He also owns 60% of closely held credit card and passport manufacturer Entrust Datacard. The company has annual revenue of more than $600 million, according to its website in June 2019, and is valued using the enterprise value-to-Ebitda multiple of one publicly traded peer, Cimpress.
The value of his cash investments is based on an analysis of dividends, insider transactions, taxes and market performance.
Joerg Appelhans, a spokesman for Quandt, declined to comment on the net worth calculation.
Father Herbert Quandt saved BMW in Germany's troubled postwar era and built the Bavarian car manufacturer into the world’s largest maker of luxury vehicles. Stefan Quandt was born in Frankfurt, Germany, in 1966, the youngest child of Herbert and his third wife, Johanna.
After his father died in 1982, Quandt inherited a stake in BMW, sole ownership of Heel, a homeopathic medicine firm, and interests in Logwin, a publicly traded logistics company, and in closely held credit card and passport manufacturer Datacard Group. He graduated from Karlsruhe University of Technology with a master's degree in business engineering in 1993. After interning at the Boston Consulting Group, Quandt worked at Datacard in Minneapolis and in Hong Kong.
Quandt joined BMW's supervisory board with his sister, Susanne Klatten, in 1996. He serves as a board member of Datacard, the Karlsruhe Institute of Technology and two foundations named after his parents. He lives in Frankfurt with his wife Katharina and their daughter.
