After graduating from the London School of Economics, Mistakidis took a position at private commodities giant Cargill where he worked in non-ferrous metals for six years. Mistakidis then joined Marc Rich & Co. in 1993 just before the firm was bought out by management and renamed Glencore. Mistakidis worked in what would become the zinc, copper, and lead department, rising to the rank of co-director in 2000. A citizen of both the United Kingdom and his native Greece, Mistakidis attained billionaire status in May 2011 with the IPO of Glencore. Despite its shares losing nearly 20% of their value since their public debut, the future is bright for Glencore. The firm announced plans to merge with mining outfit Xstrata in February 2012. The proposed all-stock "merger of equals" would spawn a $90 billion mining and marketing behemoth. Bachelor of Arts / Science, London School of Economics
