He is the founder of El-Ad Group, a real estate development and holding company, which owned the New York Plaza Hotel.

[2] When Yitzhak Tshuva was six months old, his parents, Rachamin and Julia, and their eight children emigrated to Israel as part of the Jewish exodus from Arab and Muslim countries.

One of these projects included the construction of fortifications along the Bar Lev Line, near the Suez Canal, after Israel captured the Sinai Peninsula from Egypt in the 1967 Six-Day War.

In his capacity as member of the Netanya city council, Yitzhak Tshuva was in charge of construction, development, and neighborhood restoration.

[5] In the mid 1990s, El Ad Group purchased thousands of residential and commercial properties in New York and Florida, and in the Canadian cities of Toronto and Montreal.

In 2004, El Ad Group purchased the Plaza Hotel in New York City for $675mn from the Saudi investor, Al-Waleed bin Talal.

Tshuva grew Delek Group into an energy company dealing with petrol, natural gas, insurance, biochemistry, armored vehicles and the like.

These reserves can accommodate Israel's predicted energy requirements for the next few decades while enabling the export of natural gas.

[8] In 2009, Tschuva announced his intention to make a major investment to pursue the construction of the Red Sea–Dead Sea Water Conveyance.

[10] In June 2017, Israel Chemicals Ltd. (ICL) and the Delek group sold their 50% stake in the water desalination company IDE Technologies.

[15] In October 2020, he sold 70% of Delek Israel to Lahav LR Real Estate and Uri Mantzur for NIS 525 million.
