### Attempted acquisition by Valeant Pharmaceuticals

On April 22, 2014, details were released by Valeant Pharmaceuticals and hedge fund CEO, Bill Ackman, about a $46 billion (CAD) offer presented to Allergan. Valeant proposed to exchange $48.30 in cash and 0.83 shares of Valeant per Allergan share. Allergan, Inc. stockholders would own 43 per cent of the combined company. This bid was rejected by Allergan as being too risky, claiming Valeant's business model of serial acquisitions and low organic growth being unsustainable. Soon after Valeant released a statement saying a new offer will be presented May 28, 2014, where it emerged that Valeant had increased their offer to $49.4 billion. On May 31 the offer was revised and increased to $53.3 billion.

On June 18, Valeant began its tender offer for a hostile takeover of Allergan. On August 27, 2014, Valeant and Pershing Square Capital Management asked a Chancery Judge to set a trial for September 24, 2014 to decide on whether Valeant and Pershing had properly secured enough support from Allergan shareholders to force a meeting of investors to consider replacing a majority of the company's directors. On the same day Allergan announced that they had set a December shareholder vote to decide whether the company should replace part of the board of directors. In the afternoon of August 27, Bloomberg reported that Valeant and Pershing Square had won their case with the Chancery Judge setting an October 6 date for the aforementioned trial. On November 17, 2014, Actavis, plc announced it would acquire Allergan in a white knight bid for approximately $66 billion, putting an end to Valeant's hostile takeover attempt.
