downgrade
Overweight -> Neutral
Reason
Cantor Fitzgerald on Friday downgraded Gossamer Bio to Neutral from Overweight without a price target. The firm cites the negative Phase 3 readout for PROSERA and an unclear regulatory path forward for seralutinib in pulmonary arterial hypertension for the downgrade. It is challenging to have conviction in whether Gossamer has a strong case for a path to commercialization, the analyst tells investors in a research note.
