“I’ve had a long, fulfilling career with this company, and I’m incredibly proud of what we’ve accomplished over the years,” said MacCleary. “Covestro has a vibrant new culture, a strong, diverse leadership team and a promising future here in the region. I can’t think of a better time to retire. Saying goodbye to my Covestro family won’t be easy, but I’m looking forward to starting this next chapter of my life.”

MacCleary led the North American organization through a number of transformative changes, including Covestro’s separation from Bayer AG and establishment as an independent company in 2015. His active engagement and leadership played a key role in shaping the new Covestro culture and brand in the United States. Under MacCleary’s leadership in 2018, Covestro committed to a $1.7 billion investment to build a new MDI plant in Baytown, Texas. It was the largest single investment project in the company’s history.

MacCleary’s leadership extends into the chemical industry as well, where he serves as Chairman of the American Chemistry Council’s board of directors and chairs its Sustainability Committee. He also serves on the board of directors for the National Association of Manufacturers and the executive committee for the Society of Chemical Industry.
