Key Financial Metrics

Material Changes vs. Prior Period

• Reduced Net Loss: Net loss decreased by approximately 36% year-over-year, driven primarily by a 48% reduction in R&D expenses.
• R&D Expense Reduction: R&D expenses dropped from $14.7 million to $7.7 million. This decrease was primarily due to a $5.3 million reduction in clinical trial costs following the termination of the EBO-301 trial in August 2024 and a $2.3 million decrease in personnel-related expenses due to workforce restructuring.
• Investment Activity: The company purchased $22.3 million in investments and received $31.5 million from maturities, resulting in net cash provided by investing activities of $9.2 million.
• Interest Income: Interest income decreased by 47% to $0.9 million due to lower investment balances and interest rates compared to the prior year.

Guidance, Outlook, and Risks

• Clinical Developments:
  • EBO-301 Study: On May 1, 2025, the company announced the truncated Phase 3 portion of the EBO-301 study for treatment-refractory MAC lung disease did not meet its primary endpoint. Consequently, the company suspended further development of epetraborole for this indication.
  • Chagas Disease: Phase 1 start-up activities for AN2-502998 are underway, with completion anticipated in the second half of 2025.
  • Melioidosis: The company expects to announce topline data from a 200-patient observational trial in Q2 2025 to inform a planned Phase 2 proof of concept study.
• Liquidity and Capital Resources: As of March 31, 2025, the company held $78.5 million in cash, cash equivalents, and investments. Management believes this is sufficient to fund operations for at least 12 months. The company expects to incur substantial additional losses until product candidates are approved and commercialized.
• Restructuring: In August 2024, the company reduced its workforce by approximately 50% to extend its operating capital and refocus resources.
• Internal Controls: The company disclosed that its disclosure controls and procedures were not effective as of March 31, 2025, due to material weaknesses in internal control over financial reporting (specifically regarding the control environment, period-end reporting, and IT general controls) that were previously identified and remain unremediated.
• Subsequent Events: In April 2025, the company entered into a contract modification for an existing NIAID contract, increasing eligible funding to $18.3 million and committed funding to $9.3 million.

Investor Verification Checklist

• Cash Runway: Verify the sufficiency of the $78.5 million cash balance against the burn rate, considering the suspension of the MAC program and the need for future financing.
• Internal Control Remediation: Review the company's plan and timeline for remedying the material weaknesses in internal controls over financial reporting.
• Clinical Pipeline Status: Monitor the Q2 2025 topline data release for the melioidosis observational trial and the progress of the Chagas disease Phase 1 study.
• Government Funding: Track the utilization and reporting requirements of the NIAID contract and other non-dilutive funding sources (e.g., Bill & Melinda Gates Foundation).
• Intellectual Property: Assess the impact of the discontinued MAC program on the company's IP portfolio and future royalty obligations to Anacor Pharmaceuticals.
