Cabot Corporation Announces Leadership Transition in Reinforcement Materials Segment

Cabot Corporation, a leader in the specialty chemicals and performance materials sector, is set to undergo a pivotal leadership change within its Reinforcement Materials Segment. Hobart C. Kalkstein, the executive vice president and president of the segment, will retire on January 5, 2026, marking the end of a distinguished career at Cabot. His successor, Matthew Wood, currently the vice president of global marketing and strategy for the Battery Materials product line, will take over as senior vice president and president of the segment starting June 15, 2025.

Kalkstein's legacy at Cabot is characterized by his instrumental role in enhancing the segment's financial performance and operational efficiency. His leadership not only solidified Cabot's status as a premier supplier to the tire industry but also was crucial in the development of the EVOLVE® Sustainable Solutions technology platform. Sean Keohane, Cabot's president and CEO, lauded Kalkstein for his profound business acumen and commercial expertise, which have been key to the company's achievements.

Matthew Wood, who joined Cabot in 2010 from BP, plc, is poised to bring his extensive experience in commercial strategy, operational leadership, and talent development to his new role. His previous positions within the company, including vice president of global marketing and Asia Pacific regional marketing director, have prepared him well for this transition. Keohane expressed strong confidence in Wood's capabilities to lead the Reinforcement Materials team and propel Cabot's growth in the evolving market landscape.

This leadership change is significant for the specialty chemicals and performance materials industry, reflecting Cabot's dedication to innovation and leadership in its Reinforcement Materials Segment. Wood's appointment is a clear indication of Cabot's strategic focus on sustaining growth and maintaining a competitive edge in the global market. For stakeholders and industry observers, this transition underscores the importance of strategic leadership planning in ensuring long-term success and adaptability in a rapidly changing industry.
