What Went Well and What Went Wrong

What Went Well

• Strong AD efficacy signal for ATI-2138: week 4 decreases of 77% in EASI, 64% in BSA, and 45% in PP-NRS maintained through end of treatment, with multi-omic evidence of downregulation of Th1/Th2/Th17 and fibrosis markers, validating ITK as a target .
• Clear execution roadmap across biologics: ATI-052 Phase 1a top-line results expected early 2026; Phase 1b POC trials in asthma and AD to initiate in 1H26; bosakitug Phase 2 AD data expected 2H26 .
• Management confidence and focus: “our progress is tangible and significant… we expect to drive four clinical stage product candidates in 2026… and look forward to a rich calendar of anticipated clinical milestones” — Dr. Neal Walker (CEO) .

What Went Wrong

• YoY revenue decline and wider net loss: revenue fell to $3.299M vs $4.346M in Q3 2024, and net loss widened to $14.614M vs $7.586M, driven by lower milestone/licensing revenues vs prior year .
• Elevated R&D spend as programs scale: R&D expenses rose to $13.028M vs $5.956M in Q3 2024, reflecting manufacturing, preclinical, and clinical costs across bosakitug and ATI-052, plus ATI-2138 toxicity studies .
• Non-operating headwinds: contingent consideration revaluation charge ($0.1M in Q3 2025; $1.9M YTD) and continuing licensing expense ($1.911M in Q3) weigh on reported losses .

Estimates Context

• Q3 2025 revenue of $3.299M beat S&P Global consensus of $1.405M by $1.894M; diluted EPS of $(0.12) beat consensus of $(0.14) by $0.02. Actuals reflect higher licensing contributions and contract research revenue versus consensus . Values marked * retrieved from S&P Global.
• Given recurring licensing variability and milestone timing, consensus models may need to reflect more conservative quarter-to-quarter licensing cadence and rising R&D outlays as programs progress .

Key Takeaways for Investors

• Continued pipeline momentum: multi-program cadence into 2026–2027 (ATI-2138 Phase 2 expansion, ATI-052 Phase 1a/1b readouts, bosakitug Phase 2 AD data), supporting medium-term option value .
• Solid quarter vs expectations: revenue and EPS beat S&P consensus, but YoY revenue decline and higher R&D keep losses elevated; monitor revenue mix stability and milestone timing .
• Balance sheet durability: cash of $167.209M and runway into 2H28 reduces financing overhang near-term; watch for non-dilutive monetization progress (e.g., Sun Pharma asset/royalty streams) .
• Scientific validation: additional AD Phase 2a biomarker reductions and clinical responses bolster ITK strategy; next-gen ITK IND planned for 2H26 broadens optionality .
• Catalysts: ATI-052 Phase 1a top-line (early 2026), ATI-052 Phase 1b initiation (1H26), bosakitug Phase 2 AD top-line (2H26), ATI-2138 Phase 2 initiation (1H26); positioning for narrative shifts and potential re-rating on clinical success .
• Risks: licensing/milestone variability, contingent consideration revaluation, clinical execution across multiple assets, and partner dependencies in respiratory indications .
• Trading implication: Expect news-driven volatility around 2026 readouts; near-term stock reaction likely tied to clarity on non-dilutive financing and any incremental pipeline disclosures at events .
