Shares in Bayer dropped as much as 5.7% on Monday after the embattled German company was ordered to pay $2.25 billion in damages, the highest amount yet in its ongoing litigation linked to an alleged carcinogenic effect of its Roundup weedkiller. A jury in a Philadelphia court on Friday ordered Bayer to pay $2.25 billion to a Pennsylvania man who said he developed cancer from exposure to the Roundup weedkiller, based on the chemical glyphosate. Shortly after the 0800 GMT open, Bayer shares fell 5.7% to their lowest in about eight weeks, before trimming the losses to last trade down 4.6%.
