Bayer AG’s shares dropped after the German conglomerate was ordered by a jury in the US state of Georgia to pay almost $2.1 billion to a plaintiff who claimed its Roundup weedkiller caused cancer, the latest setback in litigation that has already cost the company about $10 billion.

Bayer was ordered by a jury in the U.S. state of Georgia to pay about $2.1 billion to a plaintiff who claimed the company's Roundup weed killer caused his cancer, the plaintiff's law firms said late on Friday.

A Georgia jury found pharmaceutical and agricultural products giant Bayer liable for more than $2 billion in damages.
