As RHT works into profitability will there be temptation to introduce an increased spend to assist in further expansion? I think as they expand there will be a requirement to increase staffing, research, sales team, leases expenditure.
I still feel like RHT is sitting on the precipice of profitability. They are operating on a very small budget, cheap office space etc, there is plenty of scope for expenditure to increase in line with revenue.
my thoughts are that the current PE of 90 is not sustainable and that sentiment has driven this share price on the hope of the Siemens contract.
has anyone any estimates or guidance on how many ferrismart scans are going to be delivered going forward? Or is it the other scans that will carry RHT forward?
who has info on the commission rates being paid to Siemens or the proportion RHT get per ferrismart?

what is the price per ferrismart under this agreement? Is it $300 per scan like ferriscan was? Most likely reduced I would have thought.

well done to all holders,
