Any digs on the Wertheimer family?

Q saying Israel being saved for last got me thinking about some unknowns from old Q posts. He mentioned 4 families, one of which was the saudi royal family. One is the Rothschilds. One is the Payseurs. Could the 4th be an Israeli family?

Wertheimer family

Ranking at number two is Israel's royal family, at least when it comes to the finance world. The Wertheimers' fortune as of 2017 is estimated at 8.7 billion USD. The father of the family is German-born investor, industrialist and philanthropist Stefan (Stef) Wertheimer.

The industrial titan, founder of ISCAR Ltd., is mostly known for his efforts to promote regional peace through the construction of industrial parks in impoverished, predominantly Arab regions of Israel. In 2010, Wertheimer was awarded the Oslo Business for Peace Award for these endeavors.

Doesn't seem so bad but I'm curious if we know anything sketchy about this family?
