Cummins

Cummins Inc. is an American multinational corporation that designs, manufactures, distributes, and services engines and related technologies. It is headquartered in Columbus, Indiana, and operates globally through a network of manufacturing facilities, distributors, and service locations. The company trades on the New York Stock Exchange under the symbol CMI and is a member of the Fortune 500.

The company was founded in 1919 by Clessie L. Cummins and William Glanton Irwin to develop a reliable diesel engine for commercial use. Over the decades, Cummins expanded from a single engine design into a broad portfolio that serves on-highway trucks and buses, construction and agricultural equipment, marine applications, and stationary power generation.

Cummins’ product portfolio includes heavy- and medium-duty diesel and natural gas engines, as well as related components such as fuel systems, turbochargers, filtration, and aftertreatment systems. It provides complete power solutions, including generator sets and associated services, and markets a range of aftermarket parts and digital services through its global network.

The company emphasizes efficiency, durability, and emissions control, and has pursued alternatives such as natural gas and electrified power for various on-site and mobile power needs. Cummins operates in many countries with manufacturing, assembly, and distribution facilities that serve customers in transportation, construction, and energy sectors.
