Cummins operates through five complementary business segments: Engine, Distribution, Components, Power Systems, and Accelera. The Engine segment produces a broad range of diesel and natural gas-powered engines for heavy and medium-duty trucks, buses, and off-highway markets. The Power Systems segment provides standby and prime power generators, as well as high-horsepower engines for industrial applications like mining and marine. The Components segment offers filtration, aftertreatment, turbochargers, and automated transmissions, while the Accelera segment focuses on zero-emissions technologies such as fuel cells and electrolyzers. The company maintains a significant global footprint, generating substantial revenue internationally, particularly in China and other emerging markets. Cummins sells its products directly to original equipment manufacturers (OEMs) and supports them through an extensive aftermarket distribution and service network.
