Mallinckrodt Baker Renamed Following Acquisition

Mallinckrodt Baker has been renamed as AvantorTM Performance Materials, following its recent acquisition by an affiliate of New Mountain Capital, a New York-based private
equity investment firm.

Avantor manufactures and markets highperformance chemistries and materials around the world under two well-known and respected brand names, J.T.Baker® and Mallinckrodt® Chemicals. Headquartered in Phillipsburg, New Jersey, Avantor was acquired from Covidien in August 2010. New Mountain Capital is providing Avantor with
significant financial and strategic resources to support future growth initiatives, which include expansion in current markets and growth through acquisitions.

Under the terms of the acquisition agreement, the Mallinckrod name will remain with Covidien. Products with this brand name will continue to be manufactured and marketed by Avantor, but will eventually be transitioned to a new brand name which will be announced in the near future. Avantor intends to continue using the J.T.Baker product line brand name.

"Our new name conveys several very important ideals," said Raj Gupta, executive chairman at Avantor and senior advisor at New Mountain Capital.

"We chose Avantor because of its relevance to leadership. The word ’Avant’-as in avantgarde-evokes the bold ideas, energy, innovation and passion that we have as a company. The word ’Tor’ means mountain, and represents our aspiration to achieve new heights of performance and quality as well as our affiliation with New Mountain Capital."

Ron Harding, President of Avantor, emphasised that the company’s name is changing, but not its manufacturing process. "This transition will not impact any GMP documentation beyond what might be considered a level one name change," he said
