The sale facility will allow off market, brokerage free trading prior to the Nasdaq listing. From GMV investor relations today:

"the company also intends to establish a share sale facility to allow shareholders to sell some or all of their shares. At this stage, G Medical has not entered into any binding agreements to progress the share sale facility. Should the company enter into a binding arrangement in respect to a share sale facility, further details will be provided via the ASX announcements platform. At this stage, I cannot give any details on how pricing for the facility would be assessed, but this will be included should any announcements around a binding agreement be made."

So in the coming month, all will unfold.
