  • In a watershed decision, the Supreme Court of NSW ruled Cosette cannot terminate its Scheme for Mayne Pharma (MYX AU).

  • The hearings were the first time a material adverse change clause had been considered by an Australian court under such circumstances.

  • The transaction still requires FIRB signing off. Concerns linger over whether Cosette intends to close a South Australian plant. Mayne has previously dispelled these concerns.

The Trade:

  • Buy here.

  • Payment may feasibly occur on or before the 3rd November.

  • There could be some slippage should Cosette appeal (my read of the court doc is that they can).

  • To recap, the Scheme consideration is A$7.40/share.
