Martin Ebner (born 12 August 1945) is a Swiss billionaire businessman and investor from the municipality of Freienbach in the canton of Schwyz.
He also called for a reduction in the size of supervisory bodies and for management compensation to be based not only on a company's profits, but also on the risks involved.
In order to assert his shareholders' rights, Ebner also took legal action in individual cases, with the proceedings against the members of the Board of Directors of the then Union Bank of Switzerland (UBS) and the company itself becoming particularly well known.
At times, the portfolio of investments held by BZ Group was worth over 30 billion Swiss francs.
[8] The creeping decline of BZ Group Holding began with the sharp fall in share prices on the international stock markets that lasted for months after the bursting of the Internet bubble in 2000/2001 and the terrorist attacks on September 11, 2001.
A standstill agreement concluded with the lending banks in the summer of 2002 enabled the BZ Group to continue as a going concern.
[6] The BZ Group was left with a majority stake in the listed real estate company Intershop as its main holding.
Patinex's other disclosed holdings include the Swiss listed companies Myriad, Temenos (since 2013)[10] and Vifor Pharma.
