CEO Commentary

"Our performance in 2025 was transformative, demonstrated by 400% year-over-year clinical volume growth and pivotal Medicare coverage for breast and lung cancer," said Chris Hall, Chief Executive Officer and President. "We enter 2026 with a fortified balance sheet of approximately $240 million in cash, which allows us to expand our investments in our 'Win-in-MRD' strategy. While we are in the early stages of reimbursement, we are driving volume now to secure long-term market leadership. We expect 2026 to be a year of rapid commercial expansion, with clinical revenue projected to grow approximately five-fold as we operationalize our recent coverage wins."
