The company operates as a single segment and is classified as an emerging growth company.

Key Financial Metrics

Material Changes vs. Prior Period

• Significant Expense Reduction: Total operating expenses decreased by 55% in Q2 2025 compared to Q2 2024, driven primarily by a 74% reduction in Research and Development (R&D) expenses. This was largely due to the termination of the EBO-301 clinical trial in August 2024 and a 50% workforce reduction implemented in late 2024.
• R&D Shift: While clinical trial expenses dropped significantly, preclinical and research study expenses increased by 68% in Q2 2025 as the company prioritized the Chagas disease program (AN2-502998) and oncology targets.
• Funding Arrangements: The company recognized $3.2 million in income from the NIAID contract in Q2 2025, recorded as a reduction of R&D expenses. Conversely, the NIAID contract total funding was reduced by $9.0 million in June 2025 due to a U.S. government cost efficiency initiative, capping the cumulative contract at $9.3 million.
• Equity Transactions: In June 2025, the company exchanged 2.95 million shares of common stock for pre-funded warrants with a nominal exercise price. This transaction was accounted for as an equity-for-equity exchange with no cash proceeds.

Guidance, Outlook, and Risks

• Liquidity: Management believes current cash, cash equivalents, and investments ($71.2 million) are sufficient to fund operations for at least 12 months from the filing date. No specific financial guidance was provided.
• Clinical Progress:
  • Chagas Disease: Initiated Phase 1 start-up activities for AN2-502998 in May 2025; completed dosing of the first Single Ascending Dose cohort in August 2025. Phase 2 proof-of-concept is anticipated in 2026.
  • Melioidosis: Completed a 200-patient observational trial in October 2024. Discussions are underway with the U.S. government to fund Phase 2 development.
  • Oncology: Anticipates advancing the first oncology compound into development later in 2025 and a second in the first half of 2026.
• Material Weaknesses: The company disclosed that its disclosure controls and procedures were not effective as of June 30, 2025, due to material weaknesses in internal control over financial reporting. These include insufficient segregation of duties, lack of formal accounting policies, and deficiencies in IT general controls. These weaknesses have existed since the IPO and continue to exist.
• Risks: Key risks include the failure to raise additional capital, the high uncertainty of clinical trial outcomes, dependence on third-party manufacturers, and the potential impact of the reduced NIAID funding on the melioidosis program.

Investor Verification Checklist

• Verify the sufficiency of the $71.2 million cash runway given the ongoing burn rate and potential delays in non-dilutive funding (NIAID/BMGF).
• Monitor the remediation plan for the identified material weaknesses in internal controls over financial reporting.
• Track the enrollment and safety data from the Phase 1 trial for AN2-502998 (Chagas disease) as the primary near-term catalyst.
• Assess the impact of the NIAID contract reduction on the timeline and funding for the epetraborole melioidosis program.
• Review the terms of the pre-funded warrant exchange and its potential dilutive impact on future capital raises.
