David H. Li brings over 25 years of global leadership in advanced materials, combining strategic vision with operational excellence and cultural transformation. He assumed the role of President and CEO of Ingevity on April 7, 2025, and quickly led the company through the successful divestiture of its Industrial Specialties business and crude tall oil refinery, demonstrating his ability to execute complex corporate transitions. Prior to Ingevity, Mr. Li served as CEO, President and Board Member of CMC Materials (formerly Cabot Microelectronics) from January 2015 to January 2022. Under his leadership, CMC was repositioned around innovation and growth across semiconductor and energy markets and ultimately acquired by Entegris, representing a fourfold return to shareholders during his tenure. Before becoming CEO, Mr. Li spent nearly two decades at CMC Materials in progressively senior roles including Vice President, Asia Pacific Region (2006 2015). During this time, he drove regional growth, led cultural change initiatives and developed deep relationships across engineering, sourcing, investor relations and corporate development teams. Mr. Li is currently enhancing the strategic direction of several high-performance materials companies through board service at Hexcel Corporation, a global leader in advanced composites for aerospace, defense and industrial applications, and CoorsTek, a pioneer in technical ceramics and engineered materials for energy, semiconductor and medical markets.
