What Cummins makes

Cummins is a global power solutions manufacturer organized into five business segments: Engine, Components, Distribution, Power Systems, and Accelera by Cummins. The Engine segment builds diesel and natural gas engines for heavy- and medium-duty trucks, pickups, buses, and off-highway equipment; in 2023 it generated over $11.7 billion in revenue and delivered 1.3 million engines. Components, the largest segment by revenue in recent years, spans five businesses: engine components, emission solutions (aftertreatment), software and electronics, the Cummins-Meritor axle and brake business, and the Eaton Cummins automated transmission joint venture. It supplies OEMs and other Tier 1s with turbochargers, fuel systems, valvetrain technologies, controls, and air handling systems.

Power Systems designs high-horsepower engines and generator sets for industrial and mission-critical applications, a business with $7.5 billion in 2025 sales that has been lifted by data center backup power demand. Distribution runs sales, service, and parts through company-owned and independent locations, more than 3,700 service points worldwide. Accelera, the zero-emissions segment launched in 2023, covers batteries, electrified powertrains, fuel cells, and hydrogen electrolyzers, the last of which went through a strategic review in 2025.

Financial performance

Cummins reported full-year 2025 revenues of $33.7 billion, down 1 percent from $34.1 billion in 2024, with GAAP net income of $2.8 billion (8.4 percent of sales) and EBITDA of 16.0 percent of sales. The 2025 results absorbed $458 million of charges tied to the electrolyzer business within Accelera. A 2026 industry study of the top 100 automotive suppliers ranks Cummins 13th worldwide, with automotive-scope revenue of 20.6 billion euros in fiscal 2025 at a 9 percent EBIT margin, against 22.96 billion euros and a 10 percent margin in 2024. The euro-denominated decline overstates the change: in US dollars, total company revenue fell about 1 percent, and the 2024 base still reflected a different perimeter around the Atmus filtration separation.

Momentum improved into 2026. Second-quarter revenues hit a record $9.5 billion, up 9 percent year over year, with EBITDA at 17.5 percent of sales, and the company raised its full-year outlook, citing strength in power generation alongside recovering North American truck markets. The company employs approximately 70,000 people and paid a dividend of $7.64 per share for 2025, up from $7.00.

Ownership and history

Cummins was founded in 1919 in Columbus, Indiana, where it remains headquartered at 500 Jackson Street. The company is publicly listed on the NYSE under the ticker CMI. The last five years reshaped the portfolio: Cummins acquired Meritor in 2022, adding axles, drivelines, and brakes; separated its filtration business as Atmus Filtration Technologies, recording a $1.3 billion gain in 2024 results; and consolidated its zero-emissions technologies under the Accelera brand in 2023. Jennifer Rumsey has led the company since August 2022 and became Chair and CEO in August 2023; Mark Smith is Vice President and CFO, and Bonnie Fetch is Executive Vice President and President of Operations, covering supply chain, remanufacturing, and quality.

Certifications and quality

The company states that all Cummins manufacturing locations are certified to ISO 9001:2015, with certificates issued by third-party registrars and posted per site, including Power Systems certificates issued in 2026. Its supplier quality framework is written to ISO 9001:2015 and IATF 16949:2016, and the company's supplier handbook sets customer-specific requirements, including PPAP-based production release, for its own supply base.
