Jennifer Rumsey is the Chair and Chief Executive Officer (CEO) of Cummins Inc., a global power leader that uniquely offers its customers a broad portfolio of power solutions that best meet their needs and powers their businesses, including diesel, natural gas, battery, fuel cells, electrolyzers, and related components. In this role, which she assumed on August 1, 2023, Rumsey oversees the strategic direction, growth initiatives and global operations for the 104-year old, Indiana-based company with more than 75,000 employees worldwide.
Rumsey has focused her 25-year career on advancing technology and bringing products to market that power customers’ success and make a positive difference in the world. She co-authored Cummins’ Destination Zero strategy, the company’s strategy to go further, faster to reduce the greenhouse gas (GHG) and air quality impacts of its products and reach net-zero emissions by 2050. Rumsey is passionate about building high-performing, diverse teams and has dedicated her time at Cummins to the development of others and creating a welcoming environment where innovation thrives.
Rumsey was named President and CEO on August 1, 2022. Prior to her current role, she was President and Chief Operating Officer (COO). As COO, she successfully and strategically navigated the company’s global operations during unprecedented supply chain constraints, delivering record revenues and dramatically improving product quality and Cummins’ market position.
Prior to that role, she led Components, one of Cummins’ five business segments. The Components Segment consists of five businesses: Cummins Filtration, Cummins Turbo Technologies, Cummins Emission Solutions, Cummins Electronics and Fuel Systems and Eaton Cummins Automated Transmission Technologies. As the President of Components, Rumsey oversaw an organization of more than 12,000 employees located around the world. Under her leadership, Components launched National Standard VI (NSVI) products in China and Bharat Stage VI (BSVI) products in India designed to reduce emissions while offering industry-leading performance during an incredibly challenging environment shaped by the COVID-19 pandemic and global supply chain constraints.
From 2015 to 2019, Rumsey was Cummins’ Vice President and Chief Technical Officer and led a global technical organization of approximately 11,000 employees responsible for research and engineering across the company. She enhanced the function’s focus across product development and expanded our global technical footprint, capabilities and talent. During Rumsey’s leadership, many new products were launched that continued to advance the company’s efforts on reducing criteria pollutants from its products. As such, she has been critical in the decisions to make strategic investments in key technologies and markets to transition to lower carbon emissions products.
Rumsey’s early career focused on control systems and system engineering, initially at a fuel processing and fuel cell start-up company in Cambridge, MA.
In 2000, she moved to Cummins and has worked in a variety of engineering roles across Cummins and product life cycle areas including advanced technology development, new product development, current product engineering and product quality.
Rumsey is on the Board of Directors of Cummins Inc. and Hillenbrand. She is a member of the Society of Women Engineers (SWE), the Society of Automotive Engineers (SAE) and Women in Trucking Association. In 2020, Rumsey was recognized by SWE for her contributions to engineering and efforts to create environments that attract and retain more women engineers. Last year, she was inducted as a SAE Fellow, the organization’s highest grade of membership that recognizes and honors long-term members who have made a significant impact on society's mobility technology through leadership, research, and innovation. In May 2023, Rumsey was named a recipient of the Women’s Business Collaborative’s CEO Excellence in Gender Equity and Diversity award.
