Sanofi to Sell Winthrop for $450 Million: The drug, cosmetics and perfume unit of French oil group Elf Aquitaine said it will sell nearly all of Sterling Winthrop’s diagnostic imaging business to Norway’s Hafslund Nycomed for $450 million. The sale follows Sanofi’s agreement last week to acquire Sterling Winthrop, the prescription pharmaceutical business of Rochester, N.Y.-based Eastman Kodak, for $1.675 billion. At the time, Sanofi said it would sell Sterling Winthrop activities it considered non-strategic, for about $500 million. Sanofi said in a statement that diagnostic imaging, which involves the production and sale of contrast agents used in radiology by hospitals, clinics and radiologists, is not the sort of business it wants to engage in.
