 the Board for over 10 years. Vision One also attacks Ingevity’s past performance. While the Company has faced pressure due to external market challenges, the Board has been taking decisive actions to address those issues, such as transforming segments of our business and performing a strategic review of our portfolio – which first began in March 2024, long before Vision One first contacted the Company – to continue to deliver outperformance. The Path Forward We look forward to continuing to engage with our stockholders and providing you with further updates on our progress. We will continue to seek a constructive resolution to Vision One’s unnecessary and wasteful proxy fight, particularly as our new CEO begins his role, but only if it is in the best interests of Ingevity. We know that we have more work ahead of us, but Ingevity has promising opportunities ahead and we believe we are on the right path to unlock significant additional stockholder value by executing our strategy.
