Why it matters: The pharmaceutical giant's stock has fallen more than 50% since the end of 2021, as the company failed to find its footing since the revenue heyday of COVID vaccines.
Driving the news: Heavyweight activist investor Starboard Value has built a $1 billion stake in Pfizer with an eye on making changes, WSJ reported last night.
Just news of a campaign from Starboard is often enough to jolt a stock. Pfizer's jumped over 2% from Friday's close.
What we're watching: The activist is said to have enticed a pair of former Pfizer execs to help devise its turnaround plan, WSJ and Bloomberg reported.
One of them is former CEO Ian Read, who had left in 2018 before tapping current chief Albert Bourla.
