Outlook and guidance
FY2026 revenue guidance rose to $385M–$395M from $365M–$375M, a $20M increase at the midpoint and a $45M increase from initial February guidance.
The guidance increase primarily reflects expected TissueCypher volume growth and, to a lesser extent, ASP improvement; TissueCypher volume growth guidance remains 50%–52%.
Positive Adjusted EBITDA is expected in Q4 and full-year 2026, and in FY2027 assuming no change in strategic direction.
DecisionDx-Melanoma volume growth is expected in the mid-single digits for FY2026; Q4 may be seasonally lighter due to holiday disruptions in medical practices.
