Phase 2 EoE topline results • 2026-12-31

Base target: $6 / p=45% prob

Biggest risk

The exclusivity challenge adds a potentially consequential legal overhang to existing prescription-access friction. On October 21, before the lawsuit disclosure, Craig-Hallum cut its target from $20 to $15 while retaining Buy, citing slower-than-modeled Q3 script growth and lower forward revenue estimates.

Invalidation

Break below $4 or thesis failure.

What would change my mind?

Q2 revenue growth and lower operating expenses demonstrate commercial progress. Cantor Fitzgerald maintained Overweight after the lawsuit disclosure, judging a reversal of the FDA's exclusivity position unlikely, although that is an analyst view rather than a legal finding.

Commentary

Litigation dominated the October 23 tape: PHAT fell approximately 18% from the prior close, though the packet's adjusted-close anchor is $5.74 and outside quotes differ slightly. https://chartexchange.com/symbol/nasdaq-phat/news/ The October 21 Craig-Hallum target cut predates the suit; Cantor's October 23 view is an initial reaction, not a resolved consensus. Social, options, short-interest, and employee measurements are unavailable; their zero fields must not be read as neutral observations.

Phase 2 EoE topline results
Phathom completed enrollment in pHalcon-EoE-201 and expects topline results from its blinded treatment period in Q4 2026. Positive data could support further FDA discussions, not an immediate approval. [#SEC-8K-2026-07-30] https://www.sec.gov/Archives/edgar/data/1783183/000119312526324865/d114879dex991.htm

VOQUEZNA exclusivity litigation
BDR has sued the FDA over its refusal to receive a generic application referencing VOQUEZNA. Phathom says the FDA recognized exclusivity through May 3, 2032, but warns that an adverse outcome could permit earlier generic applications and competition. The timing and outcome are unknown.

The scheduled Q3 results should test VOQUEZNA prescription conversion, prior-authorization friction, and the moderated $310 million–$325 million 2026 revenue outlook. Q2 revenue was $74.3 million, up 88% year over year; that result does not establish Q3 performance.

Peers

Symbol	Summary
DMAC	Similar sector and market capitalization, but a clinical-stage business rather than a close commercial GI peer; unsuitable for a direct sales multiple.
EOLS	A similarly sized commercial life-sciences company, but its aesthetics market is not a direct comparator for VOQUEZNA's GI prescribing, reimbursement, or exclusivity risks.
