"On behalf of the Board, I thank Michael for over a decade of dedicated service and leadership to Avantor," said Jonathan Peacock, Chairman of the Board of Directors. "Guided by a deep commitment to the Company and our mission, Michael has built Avantor into a global player in the life sciences tools space."

Mr. Peacock continued, "We intend to identify a strong successor with a track record of delivering growth and value creation. The Avantor platform is durable and resilient, with differentiated capabilities, a broad and expanding portfolio, and a global customer base and supply chain."

"It has been an honor to lead Avantor and work alongside our team to transform the Company into a leading life science tools company and global provider of mission-critical products for life sciences and technologies customers," said Michael Stubblefield. "Avantor has a unique and differentiated role in enabling our customers to serve patients, and with the support of the thousands of incredible associates around the world, I know we have a bright future ahead. I look forward to continuing to work with the Board and leadership team while the Board identifies the right leader for the Company's next chapter."

Given his extensive history with the company, Mr. Stubblefield will be retained by the Board until February 2026 to provide ad hoc input if and as needed to ensure the new CEO settles in quickly.
