How the Top 50 automation companies lists are derived and assembled

ARC Advisory Group analysts and Control editors discover new firms to add to the Top 50 lists each year. If you find one that should be listed but isn’t, let us know, so it can be evaluated for potential inclusion. Though companies with increased sales are added and those with decreased sales relative to the others or those that have been acquired are removed, the Top 50’s basic analysis methodology hasn’t changed for years. If anything, its scope and focus on revenue generated by process control and automation activities have grown tighter.
