Samih Sawiris is the youngest son of Egyptian construction magnate Onsi Sawiris. Samih's massive development of the Swiss Alpine town of Andermatt, now in its eighth year, became a drain on the balance sheet of his company, Orascom Development. In March 2013 the company decided to spin off the project into a separate entity owned 49% by Orascom Development. Sawiris converted personal loans to Orascom Development into a 51% equity stake in Andermatt. Sawiris owns nearly 10% of construction giant, OCI N.V., which was founded by his father, Onsi, and is now run by his brother Nassef. Onsi, Nassef and brother Naguib are all billionaires.
