Cummins Founders
Clessie Lyle Cummins
A self-taught mechanic and inventor from Indiana, Clessie Cummins recognized the commercial potential of diesel engine technology when it was still largely unproven. He operated an auto repair shop and machine shop before convincing W.G. Irwin to fund his diesel engine venture. Cummins set numerous speed and endurance records in diesel-powered vehicles, including a 13,535-mile run at the Indianapolis Motor Speedway in 1931, which helped establish the company’s reputation.
William Glanton Irwin
W.G. Irwin was a successful Columbus banker and investor who provided the financial backing that made Cummins Engine Company possible. He had already funded Clessie Cummins’ auto mechanic operation before agreeing to support the diesel engine venture. His continued financial commitment during the company’s difficult early years, when the diesel engine struggled to gain commercial acceptance, kept the business alive until it achieved profitability in 1937.
Cummins Acquisitions
Cummins has grown through strategic acquisitions that expanded its product portfolio and geographic reach. The company’s acquisition strategy has focused on adding complementary technologies and strengthening its position in key markets.
The 2022 acquisition of Meritor Inc. for $3.7 billion was the largest deal in Cummins’ history. Meritor, a 110-year-old company headquartered in Troy, Michigan, brought drivetrain, mobility, braking, and electric powertrain solutions to Cummins’ portfolio. The deal added approximately 9,600 employees and positioned Cummins as a leading provider of integrated powertrain solutions for both internal combustion and electric applications.
Also in 2022, Cummins completed its $325 million acquisition of Jacobs Vehicle Systems, a Connecticut-based manufacturer of engine braking and cylinder deactivation technologies. This acquisition helped Cummins comply with emissions regulations and provisions of the United States-Mexico-Canada Agreement.
Later in 2022, Cummins acquired Siemens’ Commercial Vehicles business for approximately €190 million through its Meritor subsidiary. This deal added high-performance electric drive systems, motors, inverters, and software capabilities, along with nearly 200 employees in Germany, China, and the United States.
The company has also made investments in zero-emissions technology, including acquisitions and partnerships in battery-electric and hydrogen fuel cell systems through its Accelera business segment, formerly known as New Power.
Cummins Revenue
Cummins reported revenue of $34.1 billion in 2024. The company’s revenue has grown substantially over the past decade, driven by strong demand across its engine, components, and power systems businesses.
Cummins Marketcap
Cummins has a market capitalization of approximately $82 billion as of February 2026. The company’s valuation has increased substantially, reflecting strong financial performance and investor confidence in its strategy to lead in both traditional diesel and zero-emissions technologies.
