The big ‘new entry’ on this year’s list is, of course, Mesaieed Petrochemical Company, which has been by far the biggest Qatari company to list in the last five years. The firm went public in February, raising $880m by selling a 26 percent stake to local nationals. On its very first day of trading, Mesaieed stock rose by more than 400 percent. Formed only last September, Mesaieed is a subsidiary of Qatar Petroleum and owns Qatar Chemical Company, Qatar Chemical Company II and Qatar Vinyl. Parent firm Qatar Petroleum is planning to list four other units in the next decade.
