fter a series of new CEO appointments over the past several months, Europe’s big pharma companies have moved on and are Anow looking to strengthen or reorganize parts of their businesses. Confirmation by Germany’s Bayer AG on May 19 that it was in preliminary talks to acquire Monsanto Co. is the latest example of an emerging trend among European pharmaceutical companies to pursue M&A. Monsanto said May 18 it had received an unsolicited, non-bind- ing acquisition proposal from Bayer, a judicious move that would strengthen Bayer’s agriculture business, one of three prongs to its life sciences business that consists of pharmaceuticals, consumer health and crop science. The proposal comes just weeks after Werner Baumann stepped up from Chief Strategy Officer to become CEO of Bayer, suggesting a desire to get on with putting some of his previous planning into effect (“European Notebook: All Change In The C-Suites; Maschek/shutterstock.com Victor credit: Photo EMA PRIME Starts; French Experts Recommend Phase I Changes” — “The Pink Sheet,” March 28, 2016).
