Key Financial Metrics

Note: The filing text does not provide a specific debt figure other than a $363,000 outstanding principal on an insurance financing agreement and lease liabilities of $154,000.

Material Changes vs. Prior Period

• Net Loss Increase: Net loss increased by $1.6 million year-over-year, primarily driven by a $1.6 million increase in R&D expenses.
• R&D Expenses: Increased due to higher clinical trial costs for the DeFianCe study (Part B expansion and Part C site activity), increased manufacturing costs for clinical trial material, and consulting fees.
• G&A Expenses: Decreased by $0.5 million, attributed to lower professional fees and reduced stock-based compensation.
• Interest Income: Decreased from $0.8 million to $0.4 million due to a lower average cash balance compared to the prior year.
• Share Count: Weighted average shares outstanding increased significantly from ~27.0 million in Q1 2024 to ~41.3 million in Q1 2025, largely due to the exercise of prefunded warrants and stock options.

Outlook, Risks, and Unusual Items

• Going Concern Warning: Management has concluded that substantial doubt exists regarding the company's ability to continue as a going concern for at least 12 months from the issuance date due to the need for additional capital and an accumulated deficit of $482.8 million.
• Strategic Restructuring: On May 6, 2025 (subsequent to the period end), the Board approved a restructuring to reduce cash burn. This includes a ~50% reduction in headcount (13 full-time employees terminated, 3 converted to part-time, plus 11 prior departures). One-time costs of $0.35–$0.45 million are expected in Q2 2025.
• Clinical Progress: Updated data from the DeFianCe study showed statistically significant improvements in Objective Response Rate (ORR) and Progression-Free Survival (PFS) for sirexatamab in specific CRC patient subgroups, supporting a potential Phase 3 registrational trial.
• Liquidity Needs: The company expects to continue generating operating losses and will likely need to seek additional funding through equity financings, government programs, or collaborations to sustain operations.

Investor Verification Checklist

• Cash Runway: Verify the current cash burn rate post-restructuring and the timeline for the next capital raise given the $32.7 million cash balance.
• Restructuring Costs: Confirm the actual recognition of the $0.35–$0.45 million severance costs in the Q2 2025 financials.
• DeFianCe Study Data: Review the full clinical data release for the DeFianCe study to validate the statistical significance of the ORR and PFS improvements cited.
• Capital Raising Plans: Monitor for announcements regarding new equity offerings, debt financing, or strategic partnerships to address the going concern risk.
• Share Dilution: Assess the impact of outstanding warrants (approx. 3.3 million shares) and options (approx. 6.3 million shares) on future dilution.
