    • Strong Clinical Validation and Adoption: Executives discussed compelling clinical data and the "halo" effect between their dermatology tests, highlighting robust evidence supporting DecisionDx-Melanoma and DecisionDx-SCC, which can drive further adoption and revenue growth.
    • Effective Sales Force Expansion: Management confirmed that the expansion of the TissueCypher sales force is substantially complete—with productivity expected to materialize in upcoming quarters—setting the stage for significant organic growth in this segment.
    • Disciplined Capital Allocation Strategy: Leaders emphasized a balanced approach to deploying their strong balance sheet by prioritizing organic expansion and targeted investments, reinforcing confidence in sustainable long-term growth across multiple franchises.
    • SCC Test Reimbursement Risk: The Q&A highlighted uncertainty around reversing noncoverage decisions from MolDx despite new clinical data, which could continue to pressure revenue from the SCC test if coverage remains limited.
    • Uncertain Growth from Non-Core Tests: Executives noted that normalization of volume trends for TissueCypher and IDgenetix is still in progress and seasonality effects are not yet fully modeled, potentially delaying expected revenue growth.
    • Regulatory and Pipeline Timing Risks: Ongoing clarifications related to the FDA's final LDT rule and the extended timeline for launching inflammatory skin disease tests introduce risks of delays that could impact future revenue diversification.
    1. Capital Allocation
      Q: How will capital be allocated?

    3. MolDX LCD
      Q: Will MolDX reverse their SCC decision?
      A: Ongoing discussions with MolDX suggest a potential reversal based on new clinical evidence and expanded patient data, with management confident in an evidence‐based review approach.

    4. M&A Strategy

    7. Derm ASP Dynamics
      Q: What drives the dermatologic ASP increases?
      A: The 40% year-over-year and 13% sequential ASP increases are attributed to improved collections and higher revenue from earlier claims, though management expects these to be one-time effects rather than ongoing trends.
