On July 21, 2025, Avantor, Inc. (the “Company”), announced that it has named Emmanuel Ligner as President and Chief Executive Officer, effective as of August 18, 2025. Mr. Ligner will become a member of the Company’s Executive Leadership Team and serve as its principal executive officer. In connection with this appointment, the Company’s current Chief Executive Officer, Michael Stubblefield, who previously agreed to step down from his role as Director, President and Chief Executive Officer will cease serving effective as of August 18, 2025.

Prior to joining the Company, Mr. Ligner, age 55, served as Chief Executive Officer of Cerba HealthCare from March 2024 to March 2025. Prior to that, Mr. Ligner served as President and Chief Executive Officer of Cytiva and a Group Executive of Danaher Corporation from April 2020 to March 2024. Mr. Ligner also served in several roles at GE HealthCare from April 2008 to April 2020, including President and Chief Executive Officer, Life Sciences. Mr. Ligner began his career in biopharma as a Medical Representative at Otsuka Pharmaceutical in 1996, later serving in various roles at Abbott Diagnostics and at Whatman International. Mr. Ligner holds a B.A. in Marketing from University College of Wales and an MBA in Commerce from Université de Savoie.

In connection with his appointment as Chief Executive Officer of the Company, on July 15, 2025, VWR International Ltd., a subsidiary of the Company, entered into a contract of employment (the “Agreement”) with Mr. Ligner. The term of the Agreement is one year, with automatic annual renewals, unless it is not renewed by either party or Mr. Ligner’s employment terminates in accordance with the Agreement. Upon receipt of a work visa granting Mr. Ligner authorization to work in the United States, the Agreement will also terminate, and he will be employed by the Company on substantially consistent terms.

Mr. Ligner’s initial annual base salary is £775,000 and his target annual incentive bonus opportunity is 150% of base salary, pro-rated for 2025 based on his hire date. Mr. Ligner will be eligible to participate in the Company’s 2019 Equity Incentive Plan (the “Plan”) beginning in 2026, pursuant to which he will be eligible for an annual equity grant, with a target value of $9,000,000, as determined by the Compensation and Human Resources Committee of the Company’s Board of Directors. Mr. Ligner will also receive a one-time new hire equity award under the Plan with a target amount of $5,000,000, half of which will be granted in the form of restricted stock units and half of which will be granted in the form of premium priced stock options. These awards will vest ratably over three years, subject to the Plan’s terms and conditions.

In the event that Mr. Ligner is involuntarily terminated without “cause” or resigns for “good reason” he will receive a lump-sum payment of $75,000 for repatriation expenses and severance on terms consistent with the terms of the Company’s Executive Severance and Change in Control Plan, which is described in the Company’s current report on Form 8-K, filed with the Securities and Exchange Commission on May 12, 2025, and a copy of which will be filed with the Company’s quarterly report on Form 10-Q for the quarter ending June 30, 2025.

The foregoing description of the Agreement is a summary only and does not purport to be complete and is qualified in its entirety by reference to the full text, a copy of which will be filed with the Company’s quarterly report on Form 10-Q for the quarter ending September 30, 2025.

Avantor confirms that (1) there is no arrangement or understanding between Mr. Ligner and any other person pursuant to which he was appointed as Chief Executive Officer; (2) there is no family relationship between Mr. Ligner and any director or executive officer of the Company; and (3) there are no transactions involving Mr. Ligner that would require disclosure under Item 404(a) of Regulation S-K.
