Agreed that profit margins are low, by $20m cash proceeds from the sale is very significant for a company with a market cap of sub $20m.
The low margin is part of the reason why the shareprice isn't where it should be. The other is cash conversion. These are part and parcel of the property development industry where timings of cash settlements can be lumpy.
Hopefully the half year report (due soon) will show improvements in both of these areas which will hopefully lead to a re-rate.
