Confidence rating:

The majority of Strungmann's wealth comes from his half share of the proceeds from the sale of two pharmaceutical companies in 2005. Strungmann and his brother Thomas raised 5.7 billion euros ($7.5 billion) from the sale of generic drug maker Hexal and their 68 percent stake in Hexal's affiliate EON Labs. The value of his cash investments has been adjusted based on an analysis of dividends, taxes and market performance, and include his share of assets held in trust by Munich-based holding company Athos Service.

Some of the proceeds from the sale were used to invest in startup companies through Santo Holding. The Holzkirchen, Germany-based group is valued based on its equity value in its 2015 annual report, which is published on the German Federal Gazette.

Investments in publicly traded companies Otto Energy and 4SC are included separately in the net worth analysis. Strungmann holds 10 percent of West Perth, Australia-based Otto Energy and 24 percent of Planegg, Germany-based 4SC through his half stake in Santo Holding, whose ownership level is disclosed in the companies' annual reports. Santo is owned by the brothers' families, according to the Orbis company database, and it's attributed to Thomas and Andreas in this analysis to reflect their control of Santo's executive decisions.

Hanspeter Burkhart, a spokesman for Santo Holding in Zurich, did not respond to messages seeking comment.


Birthdate: 1950
Family: Married, 2 children

Strungmann was born in 1950 with his identical twin brother, Thomas. Both brothers obtained doctorates, Thomas in economics and Andreas in medicine.

Thomas and Andreas joined the family business Durachemie in 1979, working with their father Ernst who started it 10 years earlier. After selling the company in 1986, the brothers started Hexal, which they built into one of the world's biggest generic drug companies, according to the Ernst Strungmann Institute website.

Hexal was sold in 2005 to publicly traded pharmaceutical company Novartis. The brothers also off loased their two-thirds stake in U.S. generic drug company Eon Labs. The sales generated 5.7 billion euros ($7.5 billion) in cash for the brothers.

The brothers continued to work in partnership following the sales and invested more than 500 million euros in German biotechnology companies. Thomas told Germany's Manager Magazin in 2008 that he and his brother were planning to create something similar to Hexal.

In the same year, the brothers provided 200 million euros ($220 million) to establish neuroscience research group, the Ernst Strungmann Institute. It's fully-funded by the pair and named after their father.

Both brothers live near Munich.
