Key Financial Metrics

Material Changes vs. Prior Period

• Capital Raise: In March 2026, the company completed a Private Placement raising approximately $40.0 million in gross proceeds ($37.3 million net). This included the issuance of 8.2 million shares of common stock and pre-funded warrants for 5.8 million shares.
• Liquidity Improvement: Cash and investments increased significantly from $61.9 million in total assets (Dec 31, 2025) to $87.5 million (March 31, 2026), driven by the financing activities.
• Expense Reduction: Total operating expenses decreased by 9% ($0.99 million) compared to Q1 2025. Research and Development (R&D) expenses declined 12% primarily due to reduced Chemistry, Manufacturing, and Controls (CMC) costs and license fees, partially offset by increased clinical trial and personnel expenses.
• Stock-Based Compensation: Total stock-based compensation expense decreased to $1.5 million in Q1 2026 from $2.0 million in Q1 2025. This includes a $0.4 million incremental expense from a stock option repricing event in March 2026.
• Government Funding: The company recorded $0.7 million in income related to funding arrangements (NIAID and Gates Foundation) as a reduction of R&D expenses in Q1 2026, compared to $0.4 million in Q1 2025.

Guidance, Outlook, and Risks

• Clinical Pipeline Updates:
  • Epetraborole (Polycythemia Vera): Plans to initiate a Phase 2 proof-of-concept trial in Q3 2026, with data readouts expected starting Q4 2026.
  • Epetraborole (M. abscessus): Supporting an investigator-initiated trial (IIT) with patient screening commenced in March 2026; topline results anticipated in late 2027.
  • AN2-502998 (Chagas Disease): Completed dosing in Phase 1 trial in March 2026; Phase 1 data expected in Q2 2026. Phase 2 initiation planned for late 2026.
• Liquidity Outlook: Management believes current cash resources ($85.3 million) are sufficient to fund operations for at least 12 months from the filing date.
• Material Weaknesses: The company disclosed that material weaknesses in internal control over financial reporting identified in the prior year continue to exist as of March 31, 2026. These relate to insufficient accounting resources, lack of formal policies, and IT general control deficiencies.
• Risks: Key risks include the failure of clinical trials to demonstrate efficacy, the inability to raise additional capital, and the high uncertainty of regulatory approval. The company has no approved products and has never generated product revenue.

Investor Verification Checklist

• Capital Runway: Verify the sufficiency of the $85.3 million cash balance against the projected burn rate for the upcoming Phase 2 trials.
• Internal Controls: Review the remediation plan for the continuing material weaknesses in internal controls over financial reporting.
• Dilution Impact: Assess the impact of the 2026 Private Placement (8.2M shares + 5.8M pre-funded warrants) on existing shareholder ownership.
• Government Contract Status: Monitor the status of the NIAID contract, which was reduced by $9.0 million in June 2025, and the progress of discussions for Phase 2 funding.
• Clinical Milestones: Track the initiation of the Polycythemia Vera Phase 2 trial in Q3 2026 and the release of Chagas Phase 1 data in Q2 2026.
