I think the 2018 revenues for these five acquistions and pending acquistions is much higher than 15 $million.
I think HI-Alloy and Velocity were the $15 million in revenues they company talked about since they knew that those were the acquisitions they were in 100% control of.
My best guess is the following for 2018 Revenues:
Hi-Alloy: $12 Million Velocity: $3 Million (This is confirmed) Predominant Pumps: $1 Million Tamabra & Intesista: $8 Million (This is confirmed)
So i would put the 208 revenue around the $24-$25 million range as my best guess. This is based on the the employee count of hi-alloy and predominant pumps as the two unknowns.
