BMO Capital reiterated $PTGX Outperform; $112, and said: Main Character Energy—Momentum Increases Upside Potential for PTGX. $JNJ $TAK ABBV BMY ALMS ABVX BMO Capital added—Commercial launches and anticipated approvals could enable accelerated clinical diversification and growth for Protagonist. As of March 31, 2026, the company held cash and cash equivalents of $620M, with an anticipated runway through ~2028. Following the recent Icotyde approval (here) and launch, we could see potential additional indication approvals for the product into the decade, and a nearer-term rusfertide approval later this year (Aug. 2026 PDUFA). We continue to like collaboration revenue opportunities supportive of clinical development/diversification and look for clinical derisking of earlier-stage assets for growth beyond Icotyde/rusfertide.

$ALMS $100 is a far reach. $40-50 is most likely. hard to see anyone want to buy out it until new data comes out in the fall earliest. Approval may be 1 year away. JNJ's drug $PTGX is already on the market and has the first move advantage. Takeda's drug is more convenient as QD vs. ALMS's BID. $ALMS might have to prove the drug can significant revenue, or obtain good data in other indications, comparing to JNJ's and Takeda's, before any big pharma will buy it out. before that, $30 is the ceiling.

Wainwright said in its note: Per our Inflammatory Skin Disease Conference yesterday, our most important takeaways from the fireside chat with Alumis management were as follows: (1) envu may be the strongest oral TYK2, given the baseline characteristics and comparability between envu trials, (2) response may still deepen beyond Week 24, (3) twice-daily (BID) dosing is expected to be a temporary launch format (with QD on the way), and (4) differentiators from competition could be itch relief, quality of life, and prescribing simplicity (with simplicity strategy yet to be unveiled). We reiterate our Buy rating and 12-month price target of $25.

Clear Street⬆️ $PTGX's PT to $116 from $104 and reiterated at a Buy rating. $JNJ $ABBV BMY ALMS ABVX TAK Clear Street said in its note: We come away incrementally more constructive following our post-AAD management meeting and raise our PT to $116 from $104, with ICOTYDE further de-risking as a differentiated oral IL-23 and emerging as a potential best-in-class option in chronic indications. Its clean label (no TB test), placebo-like safety, and SKYRIZI-like, highly competitive efficacy (vs. SOTYKTU and potentially STELARA) can credibly position ICOTYDE as a preferred choice for long-term (maintenance) use, where oral convenience should further accelerate adoption. Accordingly, we increase our PsO peak penetration assumption to 18% from 15%, driving our PT revision.

Our records indicate $PTGX trades at the highest multiple of 5 & 10-year analyst consensus of all commercial-stage bios with market caps over $1B (oncology & non). This is not investment advice. We have no idea if this is a meaningful data point to understand PTGX's value proposition and/or investment thesis. $LGND trades at the 2nd highest (but LGND's gross margin was 95% in FY25). It is worth noting $ZYME is a close third. ZYME's revenues (at least near-term) are sourced via royalties (100% gross margin) just like PTGX For perspective, the attachment compares PTGX's multiples to the 5 we posted last night (appearing on the top). These are traditional comm'l-stage bios responsible for manufacturing & selling their therapies. These are not peers (outside of being biopharmas). $XBI $IBB
