Key Financial Metrics

Material Changes vs. Prior Period

• Increased Operating Expenses: Total operating expenses rose to $36.3 million for the six months ended June 30, 2026, compared to $17.1 million in the prior year period.
  • Research & Development (R&D): Increased to $21.8 million from $9.2 million, driven by CMC activities, the initiation of the angiokeratomas Phase 2 trial, and NDA submission costs.
  • General & Administrative (G&A): Increased to $14.5 million from $7.9 million, primarily due to increased headcount and costs associated with operating as a public company.
• Financing Activity: In February 2026, the company completed an underwritten public offering of 1,840,000 shares, generating net proceeds of approximately $215.8 million. This significantly improved liquidity compared to the prior period.
• Interest Expense: Non-cash interest expense related to the Ligand royalty agreement increased to $4.3 million (six months 2026) from $2.6 million (six months 2025).
• Derivative Liabilities: The contingent value right (CVR) liability was settled in January 2026 with a payment of approximately $2.0 million, resulting in a balance of $0 as of June 30, 2026.

Guidance, Outlook, and Risks

• Regulatory Progress:
  • QTORIN Rapamycin (Microcystic LMs): The FDA granted rolling review of the New Drug Application (NDA) in June 2026. The first module was submitted, with the full submission expected in the second half of 2026. A commercial launch is targeted for the first half of 2027, pending approval.
  • QTORIN Rapamycin (Cutaneous VMs): The FDA declined Breakthrough Therapy Designation in July 2026; the company plans to resubmit with additional data. A Phase 3 pivotal study is expected to commence in Q4 2026.
  • QTORIN Rapamycin (Angiokeratomas): First patients dosed in the Phase 2 LOTU trial in April 2026; topline results expected in H2 2027.
  • QTORIN Pitavastatin (DSAP): Trial initiation anticipated in H2 2026.
• Liquidity Outlook: Management believes existing cash and investments ($250.6 million) are sufficient to fund operations for at least the next 12 months. No commercial revenue is expected in the near term.
• Risks and Contingencies:
  • Going Concern: The company has incurred net losses since inception and relies on additional financing for long-term sustainability.
  • Regulatory Risk: Failure to obtain FDA approval for QTORIN rapamycin would materially impact the business.
  • Financial Obligations: The company has a significant royalty agreement liability ($22.1 million) and potential milestone payments ($5.0 million remaining) to Ligand Pharmaceuticals.
  • Market Risk: Exposure to macroeconomic factors, including inflation, interest rates, and geopolitical tensions.

Investor Verification Checklist

• NDA Submission Timeline: Verify the completion date of the rolling NDA submission for QTORIN rapamycin (microcystic LMs) and the FDA's review timeline.
• Cash Burn Rate: Monitor quarterly net cash used in operating activities to assess if the $250.6 million liquidity runway remains sufficient for the projected 12-month period.
• Ligand Agreement Milestones: Track progress toward the $5.0 million in remaining milestone payments and the impact of the 8.0%–9.8% royalty obligation on future profitability.
• Clinical Trial Enrollment: Confirm enrollment rates and safety data for the Phase 2 LOTU trial (angiokeratomas) and the planned Phase 3 trial for cutaneous VMs.
• Breakthrough Therapy Status: Monitor the outcome of the resubmission for Breakthrough Therapy Designation for the cutaneous VM program.
