Rajiv Malik to retire as President of Viatris effective April 1, 2024
Pittsburgh – Oct. 20, 2023 – Viatris Inc. (NASDAQ: VTRS), a global healthcare company, announced today that its President, Rajiv Malik, will be retiring as an executive of the Company effective April 1, 2024.
Malik is a nearly 40-year pharmaceutical industry veteran who has been responsible for the day-to-day operations of Viatris since its inception, overseeing the Company’s commercial business units, the Commercial Development, Medical, Information Technology and Quality functions, as well as Research & Development and Operations. His strategic vision and leadership played a key role in successfully integrating Viatris’ legacy companies, Mylan and Upjohn, formerly a division of Pfizer Inc.
With a unique leadership profile that combines his scientific, operational and commercial expertise, as well as his strong financial acumen, Malik has been a powerful asset for the Company. Prior to Viatris, Malik served as president of Mylan, which he first joined in 2007 following the Company acquiring a controlling stake in Matrix Laboratories Limited, where he served as chief executive officer from 2005 to 2008.
Malik will continue to serve on the Viatris Board of Directors.
Robert J. Coury, Executive Chairman of Viatris, said, “There are not enough words to express how much Rajiv Malik as both a partner and a leader has meant to me, first at Mylan and now Viatris. He is the rarest of individuals who possesses a truly unique skillset. We could not have reached all of our successes to date without him. Most especially, I have appreciated the impact he has made on all of the employees of the Company and how much he deeply cares for them. With my impending transition from the Viatris board of directors in December, I am pleased that Rajiv has agreed to remain on the board to ensure the continuity of his experience and insight on the overall operations of the Company. On behalf of myself and my fellow members of the Board of Directors, I sincerely cannot thank him enough for his leadership and dedication over these past 16 years, and the Board looks forward to his continued service.”
Scott A. Smith, CEO of Viatris, said, “It has been a true privilege to get to know and to work alongside Rajiv during this past year. His knowledge of the industry and overall command and understanding of all aspects of our business are truly extraordinary. He has the deep respect of every member of the Viatris team, and I could not have asked for a better partner during my onboarding at the Company. I am also tremendously grateful that as we continue on our path to execute on Phase 2 of our strategic plan in 2024, his immense skillset and experience will remain accessible to me as I continue to build my leadership team for the future.”
