RE: E&Y report24 Jun 2023 13:12
Two things that EY are up to in my view: firstly, is making the most of their engagement to obtain a "reasonable" level of fees fron a company desperate to establish it's credibility (will the total cost ever be disclosed?), and secondly, to use the extraordinary privileged opportunity they have to snoop around Darktrace and ultimately to make a bid for future audits (they have form here).
EY are also no doubt engaged with Darktrace's lawyers, discussing the contractual remit and what EY can and can't disclose in their report, while EY must be cognisant that their regulator, the Financial Reporting Council, would likely expect them disclose anything they find out of the ordinary, whether disclosed in the report or not, to the appropriate organisations and/or authorities.
Just my guess as to why they (EY, and not Darktrace, apparently) are taking so long. Let us not forget how long it took Darktrace to refute the claims - wasn't it less than a day?
