Tempus AI (TEM) stock is in focus after CellCarta Inc. added the company as the second commercial laboratory partner in its CDx Commercialization Lab Network for oncology companion diagnostics.

The CellCarta agreement has arrived alongside a sharp shift in momentum for Tempus AI, with the share price up 24.09% over the last day and a 30 day share price return of 26.52%, yet the 1 year total shareholder return has declined 16.42%. This suggests that recent optimism is still working against a weaker longer term record.

Most Popular Narrative: 7.1% Undervalued

Tempus AI's most followed narrative sets a fair value of $65.90 per share, compared with the last close at $61.25, which casts the recent rebound in a different light.

This data moat is what makes the business interesting.

Tempus has accumulated tens of millions of de-identified patient records and hundreds of petabytes of clinical and molecular data, assets that would take competitors years and enormous investment to replicate.

According to QuanD, the narrative focuses on Tempus AI growing into its data asset. Revenue expansion, margin uplift, and a richer earnings multiple are central to the case. Curious which assumptions carry the biggest weight in that $65.90 fair value and how sensitive the case is to slower growth or softer profitability?

Result: Fair Value of $65.90 (UNDERVALUED)

However, Tempus AI still carries risks, including ongoing net losses of US$254.4m and a share price that has fallen 16.4% over the past year.
