FY21 revenues - temporary increase?, page-2

This had me concerned also as it is a fairly large number depending on one client which was undisclosed. I actually sent an email to the CEO as who this customer was & he wrote back saying he believed their was enough information disclosed in the annual report. He's argument was they don't want to provide t much information to their competitors, but if the customers are as loyal as they make them out to be in their announcements I don't see why this is would be an issue? I saw this as a red flag & sold off.
