Fatcat, Radient is a US company but once they are deregistered, no more filings to the SEC are needed. IMO, that is why the Aussies asked Mac to send in a request to deregister the stock.
The Aussies have their own pvt company in Australia named AMDL Australia.
They just created a new website in Australia called Radient-diagnostics.com which in my opinion is meant to replace the amdlaustralia.com website their current pvt company has.
