Tom Linebarger '86

Finding your purpose is not an easy thing to do and not often found in a single experience or moment. For Tom Linebarger '86, executive chairman of Cummins, Inc.—a global power technology company that pioneers new technologies to sustainably meet the world’s growing power needs—working for an employer whose values aligned with his own was the key to finding his purpose.


Tom Linebarger '86 was appointed as executive chairman of Cummins Inc. in August 2022. Cummins Inc., a global power technology company, pioneers new technologies to sustainably meet the world’s growing power needs. Prior to this role, Linebarger served as chairman and CEO for 10 years.

Linebarger was initially attracted to Cummins’ purpose-driven approach to business reinforced during a summer internship at the Cummins MidRange Engine plant in Walesboro, Indiana. Prior to Cummins, he was an investment analyst and investment manager at Prudential Investment Corporation, working in both Singapore and Hong Kong.

In addition to his work at Cummins, he is actively involved with several global and local organizations. He has been a member of the board of directors of Harley Davidson since 2008. He is a member of the Business Roundtable (BRT), an association of chief executive officers of America’s leading companies working with government officials on crafting legislation impacting American businesses.
