Dover manages approximately 40 companies that make equipment ranging from car wash systems to aerospace components. Dover operates in four segments: Electronic Technologies, Engineered Systems, Fluid Management, and Industrial Products. The company maintains a highly decentralized management culture, with a president for each division as well as for each subsidiary company. It has kept up a long-term acquisition and divestment strategy, participating in several transactions per year. The diversification means that while Dover might benefit from some changing economic tides, it may be negatively impacted concurrently by others.
