Besieged investigative analytics software company Nuix has admitted it was not prepared to be a listed company, with chairman Jeff Bleich apologising and saying it did not develop the internal structures expected of listed companies.

At an investor day, conducted online, Nuix chief executive Rod Vawdrey took “full responsibility for the performance of the business”. He apologised for a series of missteps in its early months as a public company, which has resulted in a spectacular share price plunge of more than 60 per cent since January.
