Going concern

Affirmed

“Based on the results of the analysis and the ability to mitigate some of the risks associated with the downside scenarios, the Board has a reasonable expectation that the Group will be able to continue in operation through completion of a refinancing transaction or a M&A transaction and meet its liabilities as they fall due over the five-year period of their assessment.”
