Monsanto was founded in 1901 as a chemical company and became the largest supplier of genetically modified seed and of the glyphosate weedkiller Roundup. Bayer acquired it in 2018 and retired the name, though the liabilities came with it.
Bayer acquired Monsanto for $128 per share in cash, creating the largest agricultural inputs company in the world. Regulators required Bayer to sell substantial seed and crop protection assets to BASF. The deal brought Bayer the Roundup brand and the glyphosate litigation attached to it, which has since cost it many billions in settlements.
