Update on Legal Ruling

BTG plc: update on legal ruling

London, UK, 6 November 2017: BTG plc (LSE: BTG), the global specialist healthcare company, announces that the Court of Chancery of Delaware has issued its final order and judgement in relation to the litigation between BTG and Wellstat Therapeutics Corporation. This confirms the court's ruling, announced by BTG on 20 September 2017, that BTG has breached the distribution agreement relating to the commercialisation of Vistogard®.

As a result the distribution agreement has been terminated and BTG anticipates returning all rights to Vistogard® to Wellstat as soon as practicable. The court has also confirmed its ruling that Wellstat is entitled to damages of $55.8m plus interest and costs. BTG continues to consider appeal options. Pending the outcome of any appeal, BTG will recognise a provision of £53.5m in its results for the six months to 30 September 2017 to cover the damages and estimated interest plus costs at that date.
