Read MoreHide Full Article

Key Takeaways

  • Tempus AI posted $1.5M in positive adjusted EBITDA, driven by broad top-line strength.
  • Genomics volumes rose 33% as Oncology and Hereditary testing rebounded after sales-force stabilization.
  • Data Licensing grew 38% with $150M in new contract value while margins improved despite the Paige expense.

For the first time, Tempus AI (TEM - Free Report) reported positive adjusted EBITDA of $1.5 million in the third quarter — a landmark achievement after a decade of effort. The growth was driven by a combination of robust top-line performance across major business segments and disciplined operational execution. 

The Genomics business delivered strong momentum, with total volumes rising 33% year over year. This included 27% growth in Oncology testing and a 37% rise in Hereditary testing, reflecting broad-based strength across essentially all assays offered. 

After earlier disruptions caused by restructuring the team when introducing the MRD portfolio, the company spent multiple quarters retraining and stabilizing the sales force. During the third-quarter earnings call, management stated that the team has finally become more efficient and fully trained, enabling stronger execution. Alongside Genomics, its Data Licensing (Insights) business grew 38% during the quarter and secured an impressive $150 million in new total contract value across multiple significant agreements. 

Tempus also highlighted ongoing cost discipline and efficiency efforts that helped expand margins. Notably, the company delivered positive adjusted EBITDA even after absorbing several million dollars in incremental expenses related to the Paige acquisition, which was completed mid-quarter. The company stated that without this acquisition-related drag, adjusted EBITDA would have approached $4 million.

Myriad Genetics (MYGN - Free Report) posted adjusted EBITDA of $10.3 million in the third quarter of 2025, with a full-year forecast of $27-$33 million.
