Bayer AG

Bayer inherited the Roundup litigation by acquiring Monsanto in June 2018. Two months later a California jury returned the first verdict against it, and Bayer lost roughly $14 billion in market value within days. The May 2019 Pilliod verdict ($2 billion, later reduced) drove the stock to its lowest close in nearly seven years.

In June 2020 Bayer announced a settlement of up to $10.9 billion covering roughly 100,000 claims — approximately 75% of the inventory then pending — working out to roughly $80,000–$110,000 per claim on average. Litigation continued over later-filed claims: roughly 3,900 remained pending in the federal MDL as of July 2026, with tens of thousands more in state courts at earlier stages.

Discovery in the litigation produced the 'Monsanto Papers' — internal documents showing ghostwriting of safety literature and contacts with regulators — now publicly archived in the UCSF Chemical Industry Documents Library. On June 25, 2026, the U.S. Supreme Court ruled for Bayer on FIFRA preemption of state failure-to-warn claims; Bayer shares rose nearly 19%, their strongest session since 2003.
