Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Decline: Total revenue dropped to zero in Q3 2025 compared to $3.2 million in Q3 2024. This was driven by the cessation of revenue from contract manufacturing and R&D agreements with Rockefeller University.
• Increased Operating Loss: Net loss increased by 59% in Q3 2025 and 60% YTD 2025 compared to the prior year periods. The primary driver was a significant increase in Research and Development (R&D) expenses.
• R&D Spend Surge: R&D expenses rose 39% in Q3 and 46% YTD. The increase is attributed to expanded clinical trial activities and contract manufacturing costs for the lead candidate, barzolvolimab, specifically for Phase 3 studies in Chronic Spontaneous Urticaria (CSU).
• Investment Income: Investment and other income decreased by 34% in Q3 and 19% YTD due to lower average cash and investment balances.

Outlook, Management Commentary, and Risks

• Liquidity Position: Management states that cash, cash equivalents, and marketable securities of $583.2 million are sufficient to fund operations through 2027. However, this runway could be impacted if the company elects to pay a future $52.5 million milestone in cash under the Kolltan Settlement Agreement upon regulatory approval.
• Clinical Progress:
  • Barzolvolimab (CSU): Two Phase 3 studies (EMBARQ-CSU1 and EMBARQ-CSU2) are ongoing with enrollment expected to complete in summer 2026. Long-term follow-up data (76 weeks) showed sustained efficacy.
  • Barzolvolimab (CIndU): Phase 2 studies in Cold Urticaria and Symptomatic Dermographism met primary endpoints. A global Phase 3 study is planned for initiation in December 2025.
  • Barzolvolimab (PN & AD): Phase 2 studies in Prurigo Nodularis and Atopic Dermatitis are ongoing with initial data expected in late 2026.
  • Discontinuation: Development of barzolvolimab for Eosinophilic Esophagitis (EoE) was discontinued in August 2025 after Phase 2 results showed mast cell depletion did not translate to clinical symptom improvement.
  • CDX-622: Phase 1a study in healthy volunteers is ongoing; positive single ascending dose data was presented in October 2025.
• Risks: The company faces risks related to the uncertainty of clinical trial outcomes, the need for additional capital to fund long-term operations, and the potential dilution from future equity financings. There is also a contingent liability of up to $52.5 million payable upon regulatory approval of a surviving company product.

Key Facts for Investor Verification

• Cash Runway: Verify the $583.2 million liquidity position and the specific assumptions regarding the 2027 funding horizon, particularly the potential cash outflow for the Kolltan milestone.
• Phase 3 Enrollment: Monitor the enrollment progress of the two CSU Phase 3 trials, with completion targeted for summer 2026.
• Discontinued Program: Note the discontinuation of the EoE program and the strategic shift in focus to CSU, CIndU, PN, and AD.
• Revenue Visibility: Confirm the lack of near-term revenue visibility, as the company relies on grants and contracts which have recently declined to zero.
• Stock-Based Compensation: Review the $27.3 million in stock-based compensation expense for the nine months ended Sept 30, 2025, as a significant non-cash component of operating expenses.
