You haven't allowed for Tax, Depreciation or Amortisation. Yes...

You haven't allowed for Tax, Depreciation or Amortisation. Yes the 2015 operating profit was around $7.5m on revenue of $75m, but there was then around $3.5m expensed for Depreciation plus Interest and tax expense, so the bottom line was around $2.5m, not $7.5m.
Netcomm had a Depreciation & Amortisation expense of around $8m in 2017.
I think a more realistic optimistic estimate for 2018 is revenue around $180m, operating profit say $18m, then deduct Dep of $8m and allow for a 20% tax rate. Net profit of $8m. EPS becomes 5.3c. PE of 25 gives share price of $1.33. Hopefully they can build on that again in 2019 but the question is can they continue to win new contracts to replace completed work in 2020 and beyond? The M2M market is growing so hopefully they can.
