Question · Q3 2025
Daniel Brennan sought clarification on the drivers behind Signatera's strong Q3 ASP increase and the projected 18,000+ sequential unit growth for 2026, questioning if recent quarters' acceleration was unusual or if the 2026 forecast reflects conservatism. He also probed the impact and timing of biomarker bills on Signatera's ASPs, including the potential for a "domino effect" among commercial payers.
Answer
CEO Steve Chapman attributed Signatera's growth to new customers, extended usage by existing accounts, and new histologies, noting very low market penetration. He acknowledged the strong new patient starts in Q2 and Q3 were significant but cautioned that growth isn't always linear, suggesting the 2026 framework is a reasonable expectation. CFO Michael Brophy confirmed that biomarker state reimbursement is a factor in ASP growth, with early traction seen in Q2/Q3, and anticipates a continued "drumbeat" of improvement in 2026, potentially incentivizing broader coverage from national plans.
