Additionally, New Mountain led a series of strategic acquisitions which gave Avantor global scale, differentiated technology, increased access to distribution channels and world-class manufacturing capabilities.

New Mountain continues to be Avantors largest shareholder, with a position valued at approximately $1.5 billion based on the IPO price, not including substantial dividends received prior to the IPO.
