Sebastian Sandler's questions to Adaptive Biotechnologies (ADPT) leadership

Question · Q4 2025

Sebastian Sandler inquired about potential upside drivers for the clonoSEQ volume guide in 2026, specifically asking about community volume growth, NEO genomics contribution, guidelines, and incremental recurrence monitoring coverage. He also asked about the 2026 ASP guide of $1,400, its dependence on two called-out contracts, execution risk, and the pacing of ASP growth throughout the year.

Answer

Susan Bobulsky, Chief Commercial Officer of MRD, identified potential upside from EMR integration, particularly the pull-through on serial testing with Flatiron, and optimizing already integrated sites. She also pointed to continued focus on blood-based testing and community penetration. Chad Robins, CEO and Co-Founder, reiterated the five key drivers (blood-based testing, community, data readouts, guidelines, and EMR integrations) as areas of reinvestment and confidence. Kyle Piskel, CFO, and Chad Robins, CEO, expressed confidence in the ASP guide, noting multiple levers to achieve it despite some execution risk with key payer contracts, with pacing likely more weighted to the second half.

Question · Q2 2025

Sebastian Sandler, on behalf of JPMorgan Chase & Co., asked about the impact of the recent NCCN guideline update on multiple myeloma ordering patterns and how unique patient IDs translate to future MRD testing. He also inquired about the MRD Pharma backlog conversion to revenue and any changes in pharma customer behavior.

Answer

CCO Susan Bobulsky stated the NCCN update is a supportive tailwind, reinforcing their message in the community, but it's too early to attribute specific volume increases to it. CFO Kyle Piskel noted the pharma backlog conversion profile is largely unchanged. CEO Chad Robins added that global regulatory support for MRD as an endpoint (ODAC, CHMP) is growing, making them bullish on the pharma opportunity with minimal impact from other macro factors.
