A competition between US and French multinationals for ownership of Horizon Therapeutics Plc ended on 12 December with an all-cash offer of $27.8 billion from Amgen Inc for the Ireland-based company. The deal value is the largest healthcare merger of 2022, according to The Wall Street Journal. Sanofi SA, which also held talks with Horizon, dropped out of the discussions saying that the target company’s price expectations were too high.
