Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Collaboration and license revenue increased by $1.6 million (284%) compared to Q1 2024, driven by the timing of research activities under the Amgen collaboration agreement.
• Expense Increases: Total operating expenses rose by $6.5 million. Research and Development (R&D) expenses increased by $4.9 million, primarily due to a $2.2 million increase in laboratory supplies and studies (CDMO start-up activities) and a $1.6 million increase in facility-related expenses (new lease commencement). General and Administrative (G&A) expenses increased by $1.6 million due to higher personnel and stock-based compensation costs.
• Debt Restructuring: In December 2024, the company terminated its K2 HealthVentures loan agreement and entered into a new $52.5 million term loan facility with Silicon Valley Bank (SVB), of which $32.5 million was funded. This replaced the previous convertible debt structure.
• Capital Position: Despite a net cash burn of $37.6 million from operating activities, the company maintained a strong liquidity position of $251.7 million (excluding restricted cash) as of March 31, 2025.

Guidance, Outlook, and Risks

• Liquidity Outlook: Management believes existing cash, cash equivalents, and marketable securities are sufficient to fund operations into the first quarter of 2027.
• Development Pipeline: The company is advancing lead candidates TSC-100 and TSC-101 for hematologic malignancies (AML, MDS, ALL) in the ALLOHA Phase 1 trial. For solid tumors, seven candidates have cleared IND applications, and the FDA has cleared the IND for the multiplex T-Plex therapy.
• Collaboration: The company continues to recognize revenue from its collaboration with Amgen, which includes an upfront payment of $30 million and potential milestones exceeding $500 million.
• Key Risks:
  • Capital Requirements: The company expects to incur significant losses for the foreseeable future and will require substantial additional funding to complete development and commercialization.
  • Regulatory & Clinical: Risks include failure of clinical trials, inability to obtain regulatory approval, and manufacturing complexities associated with cell therapies.
  • Debt Covenants: The SVB loan agreement contains restrictive covenants regarding asset disposal, additional indebtedness, and equity repurchases, though it does not require financial maintenance covenants.

Investor Verification Checklist

• Cash Runway: Verify the assumption that $251.7 million in liquidity will sustain operations through Q1 2027, considering the high burn rate of ~$37.6 million per quarter.
• Debt Terms: Review the specific milestones and interest rate caps (7.00% to 9.75%) in the SVB loan agreement and the potential impact of the 5% exit fee.
• Amgen Revenue Recognition: Confirm the methodology for recognizing the $30 million upfront payment over the estimated three-year research term and the probability of achieving milestone payments.
• Manufacturing Scalability: Assess the company's ability to scale manufacturing for clinical trials, given the reliance on third-party CDMOs and single-source suppliers for critical reagents.
• Stock-Based Compensation: Monitor the trend in stock-based compensation, which increased significantly to $3.4 million in Q1 2025, impacting non-GAAP cash burn calculations.
