Key Financial Metrics

Material Changes vs. Prior Period

• Increased Operating Loss: Net loss for the nine months ended September 30, 2025, increased by 123.5% to $167.3 million compared to $74.8 million in the prior year period. This was driven by a 102.8% increase in R&D expenses and a 55.3% increase in G&A expenses.
• Debt Financing: The company entered into a $500 million credit facility in March 2025. As of September 30, 2025, $75 million (Tranche 1) was drawn, resulting in $5.3 million of interest expense for the nine-month period, compared to zero in the prior year.
• Cash Position: While cash and cash equivalents increased to $350.7 million due to debt proceeds, total liquid assets (including short-term marketable securities) decreased from $548.0 million at the end of Q3 2024 to $380.5 million at the end of Q3 2025, reflecting significant cash burn from operations.
• Share-Based Compensation: Expense increased to $9.3 million for the nine months ended September 30, 2025, from $5.3 million in the prior year period.

Guidance, Outlook, and Risks

• Clinical Trial Results: In September 2025, the company announced results for the VELA-1 and VELA-2 Phase 3 studies in hidradenitis suppurativa (HS). VELA-1 met its primary endpoint; however, VELA-2 failed to meet its primary endpoint due to a higher-than-expected placebo response. Consequently, the company did not achieve the milestones required to access Tranche 2 ($125 million) and Tranche 4 ($50 million) of its credit facility.
• Liquidity Outlook: Management believes current cash, cash equivalents, and short-term marketable securities ($380.5 million) combined with the existing debt facility are sufficient to fund operations into the second half of 2027.
• Commercial Timeline: The company expects to submit a Biologics License Application (BLA) for SLK in the third or fourth quarter of 2026, with a potential U.S. commercial launch in 2027.
• Legal Proceedings: A putative class action lawsuit (Peters v. MoonLake Immunotherapeutics) was filed in October 2025 alleging false statements regarding clinical benefits. A prior similar suit was voluntarily dismissed. The company intends to vigorously defend the claim but cannot estimate potential losses.
• Commitments: As of September 30, 2025, the company has $191.0 million in committed expenses for clinical and non-clinical development services and potential milestone payments of up to $351.8 million under its in-license agreement.

Investor Verification Checklist

• Debt Milestone Impact: Verify the implications of missing the VELA-2 primary endpoint on the company's ability to access the remaining $425 million of committed debt and the potential need for alternative financing.
• Cash Burn Rate: Assess the sustainability of the current operating burn rate (~$137 million over 9 months) against the remaining cash runway into late 2027.
• Regulatory Strategy: Monitor the company's engagement with the FDA regarding the adequacy of the current clinical evidence package for a BLA submission given the mixed Phase 3 results.
• Legal Exposure: Track the status of the Peters class action lawsuit and any potential settlement or defense costs.
• Contractual Obligations: Review the $191 million in committed purchase obligations and the potential $351.8 million in milestone payments to understand future cash outflow requirements.
