Pfizer executive Andrew Baum, a former analyst at the investment bank Citi who joined the company in June 2024 to redirect its strategic approach, has left his role as an executive vice president and chief strategy and innovation officer, the company confirmed Monday. He will continue as an adviser to Pfizer CEO Albert Bourla until the end of the year.

Pfizer and sources familiar with the matter described the move as stemming from both a sense that Baum had accomplished what he set out to do and a streamlining of Pfizer’s operations.
