Management previously indicated that they expect test volume growth to accelerate as payers add coverage, and that revenue would trend upward in the second half of 2026. Risk factors include the ongoing need to invest in sales and marketing, potential delays in Medicare coverage decisions, and competition from other dermatopathology and cancer diagnostics firms. The company also faces the inherent uncertainty of a loss‑making stage, where any slowdown in revenue growth could delay the timeline to profitability.
