Segments and operating companies

Dover's organization and segment structure has changed over its history. For example, in 1985 Dover restructured into five major subsidiaries to reflect its key markets of interest. For reporting purposes, these five major subsidiaries were represented in four sections: building industries (Dover Elevator International); electronic products (Dover Technologies); petroleum (Dover Resources); and industrial and aerospace products (Dover Industries, Dover Sargent). In 1989, Dover re-segmented into six sectors based on market activity changes: Dover Elevator International, Dover Technology, Dover Resources, Dover Industries, Dover Diversified, and Corporate Companies. After selling Dover Elevator, these segments became Diversified, Electronics, Industries, Resources, Systems and Technologies. In 2007, Dover reported four segments: Industrial Products, Engineered Systems, Fluid Management, and Electronic Technologies. Following 2014, Dover Corporation operated with four segments: Energy, Engineered Systems, Fluids, and Refrigeration & Food Equipment. The operating companies that reside within each segment are run like independent companies.
