Cabot Corporation Announces Reinforcement Materials Segment Executive Transition
BOSTON, Nov. 21, 2025 (GLOBE NEWSWIRE) -- (NYSE: CBT) today announced that it has appointed William (“Bill”) Masterson as senior vice president and president, Reinforcement Materials segment, effective November 21, 2025. Masterson succeeds Matthew Wood, who ceases to serve in this position and as an employee of the Company effective immediately.
Wood’s departure from the Company is not due to any disagreement with the Company on any matter related to the Company’s business performance, operations, financial statements, internal controls, or auditors.
Masterson joined Cabot from WR Grace in 2011 and, throughout his tenure, has held a variety of leadership positions with increasing responsibility across the Company’s businesses.

In addition to these leadership roles, Bill also had enterprise responsibility for our global commercial center of excellence. Masterson’s extensive experience managing complex global operations combined with deep expertise in commercial strategy, positions him well to advance Cabot’s objectives in his new role.
