Avantor announced that Mary Blenn will serve as Executive Vice President and Chief Operating Officer, effective immediately. In her new role, Blenn will oversee the company’s manufacturing and supply‑chain operations, aligning them with Avantor’s growth strategy and the broader “Avantor Revival” plan launched by CEO Emmanuel Ligner.
Blenn brings more than 30 years of global operations experience, most recently as Senior Vice President of Global Operations & Supply Chain at Cytiva and previously in senior roles at GE. Her track record includes leading large‑scale manufacturing and logistics transformations, driving cost discipline, and scaling operations in the life‑sciences and medical‑technology sectors—skills that align closely with Avantor’s current focus on operational efficiency and margin improvement.
Avantor’s financial performance has been under pressure, with Q3 2025 revenue at $1.62 billion, a 5% year‑over‑year decline, and an adjusted EBITDA margin of 16.5%. The company is pursuing a cost‑transformation program that targets run‑rate savings by 2027 and aims to reduce net leverage while strengthening shareholder value. Blenn’s appointment is a key step in executing that program, as her expertise is expected to accelerate cost‑saving initiatives, improve supply‑chain resilience, and enhance manufacturing quality across Avantor’s global footprint.
CEO Emmanuel Ligner said, “Having worked with Mary before, I’ve seen firsthand her ability to transform complex operations into agile, high‑performing systems. Her track record of leading large‑scale manufacturing and supply‑chain organizations through periods of rapid growth and change makes her exceptionally well‑suited for this role.” Blenn added, “I am honored to join Avantor at this important time in its revival. I look forward to partnering with Emmanuel and the talented teams across Avantor to strengthen our manufacturing and supply‑chain capabilities, embed lean principles into everything we do, and serve our customers with greater speed, reliability, and impact.”
The appointment signals Avantor’s commitment to operational excellence as it navigates a challenging market environment. By placing a seasoned operations leader at the helm of manufacturing and supply chain, Avantor aims to unlock efficiencies that will support its cost‑saving targets, improve margin stability, and position the company for sustainable growth in both its Laboratory Solutions and Bioscience Production segments.
