Key Financial Metrics

Material Changes vs. Prior Period

• Financing Activity: The company raised approximately $107.6 million in net proceeds from an underwritten public offering of 23,000,000 shares of common stock in February 2026. This significantly increased cash balances from $85.4 million at year-end 2025 to $177.9 million at March 31, 2026.
• Operating Expenses: Total operating expenses remained relatively flat ($31.1 million vs. $31.2 million). R&D expenses decreased by $1.5 million, driven by lower manufacturing costs and the completion of an adolescent run-in study, partially offset by increased professional fees for Biologics License Application (BLA) preparation. G&A expenses increased by $1.5 million due to commercial consulting and personnel costs.
• Investing Activities: Net cash provided by investing activities was $29.0 million, primarily from the maturities of marketable securities, compared to $14.4 million in the prior year.
• Equity Structure: The company issued 500,000 shares of Series A Convertible Preferred Stock in exchange for common stock held by a specific stockholder during the period.

Guidance, Outlook, and Risks

• Regulatory Milestones: In February 2026, the FDA granted Breakthrough Therapy Designation to nomlabofusp. The company plans to initiate a rolling BLA submission in June 2026, targeting a U.S. launch in the first half of 2027 if approved.
• Clinical Development: The company plans to provide topline data from its ongoing open-label study in Q2 2026 and initiate dosing for a global confirmatory Phase 3 study in mid-2026.
• Liquidity Outlook: Management expects current cash, cash equivalents, and marketable securities ($200.4 million) to fund operations into the second quarter of 2027.
• Risks: Key risks include uncertainties in clinical trial results, patient recruitment delays, manufacturing scalability, and the ability to secure additional financing if needed. The company has incurred significant losses since inception and expects to continue doing so until commercialization.

Investor Verification Checklist

• Cash Runway: Verify the $200.4 million liquidity position and the projection to fund operations through Q2 2027.
• BLA Timeline: Confirm the June 2026 rolling BLA submission schedule and the criteria for the FDA's acceptance of skin FXN as a surrogate endpoint.
• Expense Trends: Monitor the increase in G&A expenses related to commercial readiness and the trajectory of R&D costs as the Phase 3 study initiates.
• Preferred Stock Terms: Review the terms of the Series A Convertible Preferred Stock issued to Blue Owl Healthcare Opportunities IV Public Investments LP, specifically the conversion ratio and voting rights.
• Capital Needs: Assess the potential need for additional capital if clinical timelines are delayed or if the company pursues broader commercialization efforts earlier than planned.
