On 7 August 2020, Cello announced that the Court had sanctioned the Scheme at the Court Hearing held earlier that day.

Following the delivery of a copy of the Court Order with the Registrar of Companies earlier today, Cello and Bidco are pleased to announce that the Scheme has now become Effective.
