BOSTON, July 30, 2026 (GLOBE NEWSWIRE) — Cabot Corporation (NYSE: CBT) announced today that Sean Keohane has notified the Board of Directors of his decision to retire as President and Chief Executive Officer (CEO) of the Company and to step down from the Company’s Board of Directors, each effective September 30, 2026. Erica McLaughlin, Executive Vice President, Chief Financial Officer (CFO) and Head of Corporate Strategy, has been elected to succeed Keohane as President and CEO, and to serve on the Board as a member of the class of directors whose term expires at the 2029 Annual Meeting of Stockholders, both effective October 1, 2026.

Keohane will remain with the Company in an advisory capacity through the end of the 2026 calendar year to ensure a smooth transition. In connection with McLaughlin’s appointment, the Company has commenced a search process to identify a new CFO.

McLaughlin joined Cabot in 2002 and has held a broad range of senior leadership positions within the Company’s finance and strategy organizations and Reinforcement Materials business. Prior to her current role, which she has held since 2018, she was Vice President, Business Operations for Reinforcement Materials and General Manager of its tire business and Vice President of Investor Relations, positions from which she has developed a deep understanding of finance, corporate strategy and business operations. She has played a key role in shaping the company’s strategic direction, driving operational discipline, and advancing major initiatives across the portfolio. She also currently serves on the Board of Directors of Azenta Life Sciences (Nasdaq: AZTA) and on the Advisory Board of FM Global.

“Erica brings deep industry expertise and a strong understanding of Cabot’s businesses, markets and global operations. This experience, coupled with her commitment to the company’s long-term strategic priorities, positions her exceptionally well to lead Cabot,” said Board Chair Michael Morrow. “Our decision to appoint Erica as the next President and CEO reflects a thoughtful and deliberate succession planning process. Her deep knowledge of the organization and commitment to the values and culture that have been integral to Cabot’s success will provide continuity as we execute this leadership transition. We believe she brings the leadership, discipline and strategic clarity needed to lead Cabot forward and deliver on our long-term vision.”

“I am deeply honored to succeed Sean as President and CEO and lead Cabot into our next chapter,” said McLaughlin. “Having been at Cabot for close to 25 years, I know firsthand the strength of our people and our businesses. I look forward to working with the Board and our global team to build on our success, grow the company by supporting our customers with innovative chemistry solutions to advance their businesses, and create value for our stockholders.”

Keohane has had a distinguished career spanning nearly 25 years with Cabot and has served as the company’s President and CEO since 2016. During his tenure, he has led the company through a period of meaningful change; focusing the portfolio, strengthening its core businesses, developing its entry and scale up into battery materials, advancing the company’s sustainability agenda, and deepening the company’s commitment to operational and commercial excellence. Under his leadership, Cabot has delivered strong performance and generated long-term value for shareholders.

“The Board is deeply appreciative of Sean’s exceptional leadership and distinguished career at Cabot,” said Morrow. “We extend our congratulations on a well-deserved retirement. During his tenure as CEO, Sean provided strong, steady and thoughtful leadership, focusing the company’s portfolio around its core businesses and advancing new strategic long-term growth priorities. His collaborative leadership style has strengthened our organization and leadership team, leaving a strong foundation for continued success in the years ahead.”

“It has been a tremendous privilege to lead Cabot and to work alongside such a talented and dedicated global team,” said Keohane. “I am incredibly proud of what we have accomplished together and the foundation we have created. I am confident Cabot is in excellent hands under Erica’s leadership. We have worked side by side for almost my entire tenure as CEO and I have seen first-hand her strong leadership, operational discipline, and sharp strategic mind. Erica is a trusted and highly capable leader with deep knowledge of our business and a commitment to our people, the culture, and the unique heritage of this great company. I look forward to supporting a seamless transition in the months ahead.”
