In 1952, Sawiris established his own construction company, Onsi & Lamei Co, which began as a road and waterways contractor. In 1961, the business was nationalized under then Egyptian President
Gamal Abdel Nasser and later became known as the El Nasr Civil Works Company. Mr. Sawiris continued to run the nationalized business for five years. He was prevented from leaving the country for six years in the 1960s. After a period of time in
Libya, he returned to Egypt in 1976 during the regime of Egyptian president
Anwar Sadat and founded Orascom for Constructions and Trade as a general contracting and trading company. The name was later changed to
Orascom for Construction Industries, and the investment portfolio expanded in the 1980s and the 1990s to include tourism, hospitality, computing, and cell phone networks, under the government of Egyptian president
Hosni Mubarak. In 2003, the Sawiris family held the three largest stocks by market capitalization on the Cairo exchange and is currently setting up to be on the American stock exchange: Orascom Telecom, Orascom Construction Industries and MobiNil. He was estimated to be worth approximately $1.2 billion according to
Forbes in 2017. == See also ==
