Model Update Post 2Q Print

▲Price Target (Dec-27):$149.00

Prior (Dec-26):$113.00

Following the 2Q results (see our note), we are updating our model for PTGX

and establishing our Dec-2027 PT. Key changes in our model include: 1)

increasing Icotyde penetration in psoriasis based on the robust adoption dynamics

observed in 2Q, 2) refining Rusfertide penetration in PV heading into the launch

later this fall, 3) adjusting Icotyde’s PoS in indications outside of PsO assuming

read-through from earlier data, and 4) rolling the period over. Reflecting the

changes, we establish our Dec-2027 PT of $149 (previously Dec-2026 PT of $113).
