Bayer acquires Roundup (2018)

Bayer completed the acquisition of Roundup on 7 June 2018 for $63 billion, buying from Monsanto.[1]

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.
