Despite instability in Egypt, Mohamed Mansour and his two brothers, Yasseen and Youssef (also billionaires), are prospering thanks largely to their Mansour Group's Caterpillar tractor and equipment sales in eight African countries and Russia. The company generated more than $6 billion in revenue last year, a 16% increase over 2012, with 60% coming from outside Egypt. To sustain its growth, Mansour Group's Unatrac subsidiary, which holds the Caterpillar business and is run by Mohamed's son Loutfy, signed a $700 million syndicated credit facility last June. In Egypt the company reports strong sales of cigarettes through its Philip Morris unit, and food through its Metro Supermarkets.
