Upstream Bio: The Reset Is The Opportunity, Initiating At Buy

Upstream Bio: The Reset Is The Opportunity, Initiating At Buy

I am initiating a Buy rating on Verekitug, the lead asset of Upstream Bio, a small-cap biotech trading at an enterprise value under $200M. Verekitug's quarterly dosing and differentiated TSLPR mechanism offer competitive efficacy in severe asthma and CRSwNP, with strong phase 2 data supporting further development. UPB's key catalysts include FDA interactions, phase 3 trial initiations in 2027, and a COPD phase 2 readout, all of which could drive significant re-rating.
