It has to be between $2 and $4. Let's make it $3. Which could result in $500k out of $3M in Q4.
The CEO guided $4M in March/April? My impression is that revenues from liquid sales beat expectations while the hospital orders from the UK were delayed. Perhaps if they can deliver the latest order to the UK on time revenue for 2020 will be $4.5M. It doesn't really matter.
We have a run rate of $6M + $2.5M from oil and gas = $8.5M already for next year. $20M target is getting closer.
