Key Financial Metrics

Note: Revenue is derived from collaboration agreements, primarily with Acadia Pharmaceuticals. The company has no product sales revenue.

Material Changes vs. Prior Period

• Revenue Growth: Revenue increased 48% quarter-over-quarter and 133% year-over-year (YTD), driven by the recognition of revenue from the Acadia Pharmaceuticals collaboration agreement.
• Expense Increases: Operating expenses rose due to increased personnel costs and R&D activities. R&D expenses increased by $1.9 million in Q3 and $5.2 million YTD, primarily due to higher costs for the zorevunersen program and personnel-related expenses.
• Liquidity Position: Total cash, cash equivalents, and marketable securities increased significantly from $201.4 million at year-end 2023 to $269.2 million at September 30, 2024. This increase was fueled by a follow-on public offering in April 2024 that generated $119.9 million in net proceeds.
• Investing Activities: The company invested heavily in marketable securities, purchasing $138.1 million in securities during the first nine months of 2024, compared to no purchases in the same period in 2023.

Guidance, Outlook, and Risks

• Clinical Progress: In August 2024, the FDA removed a partial clinical hold on higher doses of zorevunersen. The company is on track to provide a regulatory update on Phase 3 registrational plans in the second half of 2024. The OSPREY study for STK-002 (ADOA) has been delayed to prioritize zorevunersen.
• Liquidity Outlook: Management believes current resources ($269.2 million) are sufficient to fund operations and capital expenditures through at least the end of 2025.
• Capital Needs: The company expects to continue incurring net losses for the foreseeable future and will require additional financing to advance clinical development and commercialization.
• Key Risks:
  • Failure to achieve regulatory approval or demonstrate efficacy in clinical trials.
  • Dependence on the Acadia collaboration for a significant portion of revenue and pipeline development.
  • Need for future capital raises, which may be dilutive or unavailable on favorable terms.
  • Intellectual property challenges and reliance on licensed technology (e.g., TANGO platform from University of Southampton).

Investor Verification Checklist

• Cash Runway: Verify the accuracy of the "end of 2025" liquidity projection against current burn rates and potential clinical trial cost escalations.
• Acadia Revenue Recognition: Review the specific terms of the Acadia agreement to understand the sustainability of the current revenue stream and the timing of future milestone payments.
• Regulatory Timeline: Monitor the upcoming Phase 3 regulatory update for zorevunersen expected in late 2024 for any delays or new requirements.
• Dilution Risk: Assess the impact of the April 2024 follow-on offering and potential future equity raises on existing shareholder value.
• Stock-Based Compensation: Note that stock-based compensation was $20.3 million for the nine months ended September 2024, a significant non-cash expense impacting net loss.
