In light of the reduced ownership of the common stock, par value $0.01 per share (“Common Stock”) of Avantor, Inc. (the “Company”) by affiliates of New Mountain Capital, L.L.C.

Prior to its termination, the Investor Rights Agreement granted New Mountain the right to nominate directors to the Company’s board of directors (the “Board”) as follows: so long as affiliates of New Mountain continued to own (i) at least 50% of the shares of the Common Stock that New Mountain owned immediately following the initial public offering of the Company, New Mountain would be entitled to nominate three directors; (ii) at least 25% but less than 50% of the shares of our Common Stock that it owned immediately following the consummation of the initial public offering, New Mountain would be entitled to nominate two directors; and (iii) at least 10% but less than 25% of the shares of the Common Stock that it owned immediately following the consummation of the initial public offering, New Mountain would be entitled to nominate one director.
