52-week range
As of 5 Oct 2026, 17:35What does Bayer do?
Bayer stands on three legs: seeds and crop protection for farmers, prescription medicines, and over-the-counter products for your medicine cabinet. It greatly expanded its farming business by buying US company Monsanto in 2018. That deal also brought thousands of lawsuits over the weedkiller glyphosate.
From the medicine cabinet: Aspirin, Bepanthen and Rennie are Bayer brands. Bayer 04 Leverkusen also carries its name.
