This week marks my fourth month with Ingevity. As I've traveled to our sites and met with our teams globally, I've been energized by the passion and pride our people bring to work every day. The Ingev-Away, our shared values and mission to purify, protect, and enhance the world around us, is deeply embedded across the company. And what I consistently hear from our organization is that they feel we have reached an inflection point and are ready to start winning again.
