Youssef Mansour, a part owner of Mansour Group, maintains a lower profile than his billionaire brothers Mohamed and Yasseen. Thanks in large part to its Caterpillar dealerships in Russia and eight African countries, Mansour Group's revenues topped $6 billion in 2013, a 16% increase over 2012. In Egypt, sales at the company's Metro supermarkets are strong. Youssef helped build Metro into the country's largest supermarket chain. Last year Emirati billionaire Majid Al Futtaim offered to buy the chain for some $300 million but no transaction has taken place. Through its private equity arm, the family made investments in a logistics firm in 2012, and this year it took a minor stake in Reddam House, a South Africa-based school that has plans to expand in other African countries.
