"During the third quarter, we delivered test results to more patients than ever before, improved profitability, and achieved key milestones in our pipeline of innovative cancer diagnostics," CEO Kevin Conroy said in a statement.
But while the company has "made progress, our execution during the third quarter and updated outlook for the full year don't reflect our full potential," Conroy said. "We plan to accelerate growth in 2025, and our long-term outlook remains strong."
