Tempus AI (TEM) is back in focus after CellCarta added the company to its CDx Commercialization Lab Network, linking Tempus Hub ordering to CellCarta testing and tightening access to oncology companion diagnostics for U.S. providers.

However, the year-to-date share price return is down 16.53% and the 1-year total shareholder return is down 14.49%, suggesting recent momentum is building after a weaker stretch.

Another View: Tempus AI Looks Expensive On Sales

While the user narrative points to roughly 25% upside for Tempus AI, the current P/S ratio of 6.6x tells a more cautious story. It sits above both peers at 5.5x and the US Life Sciences industry at 4.1x, even though the fair ratio sits higher at 7.7x. That gap leaves a mix of perceived upside and valuation risk.
