Key Financial Metrics

Material Changes vs. Prior Period

• Reduced Net Loss: Net loss decreased by 16% in Q2 2024 compared to Q2 2023, and by 26% on a year-to-date basis. This improvement is primarily driven by a reduction in operating expenses.
• Operating Expense Reduction: Total operating expenses decreased by 11% in Q2 and 21% YTD.
  • Research & Development (R&D): Decreased 17% in Q2 and 27% YTD. The decline is attributed to reduced clinical outside services (completion of Phase 2 ARCHER trial in 2023) and lower contract manufacturing costs for ANX005.
  • General & Administrative (G&A): Increased 15% in Q2 due to higher consulting and professional services, but remained relatively flat (-1%) YTD.
• Increased Interest Income: Interest and other income increased 59% in Q2 and 45% YTD, driven by higher average cash balances and favorable interest rates.
• Capital Raise: In June 2024, the company raised approximately $116.8 million in net proceeds through the sale of common stock and pre-funded warrants. This significantly bolstered short-term investments.

Guidance, Outlook, and Risks

• Clinical Progress:
  • GBS (ANX005): Announced positive results from the pivotal Phase 3 trial showing faster recovery. Plans to submit a Biologics License Application (BLA) in the first half of 2025.
  • Geographic Atrophy (ANX007): Initiated dosing in the global pivotal Phase 3 ARCHER II trial in August 2024. Topline data expected in H2 2026.
  • Autoimmune (ANX1502): Completed bridging study; proof-of-concept study in cold agglutinin disease expected to report data in Q4 2024.
• Liquidity Outlook: Management projects that existing cash and investments ($368.7 million) will fund operations into the second half of 2026. The company expects to continue incurring losses for the foreseeable future.
• Financing Programs:
  • 2021 ATM Program: $42.3 million remaining; registration expires August 15, 2024.
  • 2024 ATM Program: $100.0 million capacity; no sales made as of June 30, 2024.
• Risks:
  • Dependence on successful clinical trials and regulatory approval for revenue generation.
  • Need for substantial additional financing to achieve long-term goals.
  • Regulatory uncertainty regarding the acceptance of data from foreign clinical trials (e.g., GBS trials conducted in Southeast Asia).
  • Competition in the Geographic Atrophy market with two FDA-approved therapies.

Investor Verification Checklist

• Cash Runway: Verify the accuracy of the "second half of 2026" funding projection against current burn rates and potential clinical trial cost escalations.
• Regulatory Strategy: Confirm the FDA's acceptance of the Real-World Evidence (RWE) study comparing the GBS patient population in the US vs. Southeast Asia, which is critical for the 2025 BLA submission.
• ATM Program Expiry: Monitor the status of the 2021 ATM program, which expires in August 2024, and assess the company's ability to raise capital via the new 2024 ATM program or other means.
• Dilution: Review the impact of outstanding pre-funded warrants (41.3 million shares) and common warrants (8.1 million shares) on future share count and dilution.
• Clinical Timelines: Track the enrollment and data readout dates for the ARCHER II (GA) and ANX1502 (Autoimmune) trials to ensure they align with management's guidance.
