Sanofi-Aventis makes counterbid for Zentiva
Sanofi-Aventis, the French drug manufacturer, said on 18 June that it was planning to make a counterbid of $2.57bn for the shares in Zentiva, the Czech pharma firm, that it does not already own.
Zentiva, a generic drugs company based in the Czech Republic, has rejected an ``opportunistic'' US$2.32bn takeover bid by financial group PPF and Italian insurer Generali, which together own 19% of Zentiva.
