Química Farmacéutica Bayer, S.L.

Bayer's presence in Spain dates back to 1899, when the company Bayer y Cía. was founded to commercialize dyes. In 1925, the Bayer Group already had shares in the companies that would later become Química Farmacéutica Bayer and Agfa-Gevaert, respectively.

In the 1960s, Bayer gave a new boost to its presence in Spain by creating Bayer Hispania S.A. in 1966 and later Bayer Hispania Comercial, S.A., which would later be absorbed by the former. Química Farmacéutica Bayer, S.A. became part of the Bayer Group in 1981, with the first major shareholder restructuring of the group taking place in 1986, when the shares of all the companies were concentrated in Bayer Hispania S.A.

Throughout these one hundred years, Bayer has established its industrial fabric in Spain with important factories distributed throughout the country.
