Credit Suisse attributed the downgrade to the company's challenging product story and limited near-term catalysts. The firm feels a downward rating move is warranted ahead of patent expirations of key products Viagra and Lyrica.

The firm also lowered its second quarter estimates for Xtandi but raised its estimates for Ibrance and Xeljanz.

Meanwhile, the firm said the focus of the conference call will be Pfizer's business development priorities as investors expect the company to add more growth drivers to the story.

Barclays has a $36 price target on the shares of Pfizer.
