Business Overview

-The Company is a global leader in the design, manufacturing, sale and servicing of diesel and alternative fuel engines and related components and technologies, such as filtration, aftertreatment, turbochargers, fuel systems, control systems, air handling systems, automated transmissions, electric power generation systems, batteries, hydrogen generation and fuel cell products.

In the first quarter of 2023, the Company restructured specific areas within its operating segments. In the Components segment, the Company carved out its electronics business into the software and electronics business, while combining the turbo technologies and fuel systems businesses into the new engine components business. The Company also changed the name of its filtration business to Atmus. In March 2023, the Company rebranded the New Power segment as Accelera. As of December 31, 2023, the Company is organized into five business segments:

Cummins revenue by segment(2022年度)
  • Engine: The segment manufactures diesel and natural gas engines for on-highway and off-highway vehicles including medium-duty and heavy-duty buses and trucks, passenger vehicles, agricultural equipment, mining vehicles, and marine vehicles.
  • Power Systems: The segment manufactures high-speed high-horsepower engines for applications including mining, rail, defense, and commercial marine. The segment also provides power generators for consumer, commercial, industrial, data centers, and health care applications.
  • Components: The segment is divided into six businesses: Atmus, the former Filtration business, which manufactures filters, coolant and chemical products; Engine components, which produces turbochargers, fuel systems, and valvetrain technologies; Emission Solutions, which designs and manufactures exhaust after-treatment technologies and solutions; Axles and brakes, which designs and manufactures drivetrain systems including axles, drivelines, brakes and suspension systems; Software and electronics, which develops and remanufactures electronic control modules, sensors, power electronics, and actuators; and Automated transmissions, which develops and supplies automated transmissions for heavy duty commercial vehicles.
  • Distribution: The segment provides sales, services and support for the full range of the Company’s products.
  • Accelera: The segment designs, manufactures, sells and supports electrified power systems ranging from fully electric to hybrid and also designs and manufactures battery modules, packs and systems for commercial, industrial and material handling applications. It also designs, manufactures and supports hydrogen production solutions.

-Of the Company’s five business segments, the Engine segment, Components segment and Accelera Segment supply products to the automotive industry.
