Avantor Board Chairman Transition: What it Means for the Company

Avantor, Inc. made an exciting announcement about a change in leadership recently. Gregory L. Summe, a current independent director, will be stepping up to serve as the next Chairman of the Board starting on January 1, 2026. This transition comes as Jonathan Peacock, who has dedicated nearly nine years of service to the Board, has decided to step down as Chairman and as a director at the end of 2025.

Mr. Summe, who has been on the Avantor Board since 2020, has played a vital role as the Chairman of the Nominating and Governance Committee and as a member of the Compensation Committee. With a wealth of experience as a CEO and Board member in the Tools and Life Sciences sector, Mr. Summe is well-prepared for this new leadership position.

After his announcement to step down, Mr. Peacock expressed how much of a privilege it has been to work alongside his Board colleagues in steering Avantor towards a strong position in the Life Sciences sector and managing the transition to a new CEO. With Emmanuel Ligner taking the helm as the new CEO and the recent addition of Greg Lucier to the Board, Mr. Peacock highlighted that now is the right moment for new Board leadership.

As Mr. Summe steps into his new role, he looks forward to harnessing the collective talent of the Avantor team to continue executing the company’s strategy for growth and profitability. He also expressed gratitude to Mr. Peacock for his remarkable leadership, guidance during the CEO transition, and unwavering commitment to Avantor.
