    Our Owners 

    Avantor is owned by New Mountain Capital, which acquired the company from Covidien Inc. in 2010. 

    New Mountain Capital is a New York-based private equity firm that emphasizes business building and growth, rather than debt, as it pursues long-term capital appreciation. The firm currently manages private and public equity funds with approximately $12 billion in aggregate capital commitments. New Mountain Capital seeks out what it believes to be the highest-quality growth leaders in carefully selected industry sectors and then works intensively with management to build the value of these companies.  

    Our Leadership Team

    Avantor’s Executive Leadership Team includes experienced managers and scientists who share a common goal: to build the strength of our global performance and further establish Avantor as a global supplier of ultra-high-purity life sciences materials with strict regulatory and performance specifications.
