Control's Top 50 Automation Companies

Find out who has made our list of top automation companies worldwide and nationwide throughout the years.

How the Top 50 are compiled

To develop the Top 50 lists for North American and worldwide, the analysts at ARC Advisory Group use publicly available financial data wherever possible from the leading firms supplying process control and automation technologies. Even though firms with increased sales are added and those with decreased sales relative to the others or those that have been acquired are subtracted, the Top 50's basic analysis methodology hasn't changed for several years. When these big companies have businesses unrelated to automation and/or don't provide details of the extent of their process control activity, ARC uses other publicly available information and its database to calculate a meaningful determination of the scope of their automation business. This scope is based on ARC's definition of which technologies constitute control and automation and which do not. If anything, ARC's scope and focus on revenue generated by process control and automation activities has only grown tighter.

  • Process automation systems and related hardware software and services;
