(Reuters) - Pfizer ( PFE ) CEO Albert Bourla plans to meet activist investor Starboard Value, the Financial Times reported on Tuesday, citing people familiar with the matter.

Bourla and at least one other director will hold talks with Starboard next week, the report said.

Pfizer ( PFE ) declined to comment, while Starboard Value did not immediately respond to a Reuters request for comment.

Reuters reported on Sunday, citing sources, that Starboard Value has taken a stake of about $1 billion in Pfizer ( PFE ) and wants the U.S. drugmaker to make changes to turn its performance around.
