Tempus AI Inc (NASDAQ:TEM) stock is trading lower on Monday as the stock is pulling back from an approximately 20% surge over the last week.

Personalis Deal Draws Attention

The recent surge in the stock was driven by momentum from Phase 3 INTerpath-001 results from Merck & Co. Inc. (NYSE:MRK) and Moderna Inc. (NASDAQ:MRNA) of intismeran autogene (a custom mRNA neoantigen therapy) paired with Keytruda for advanced melanoma.

The data puts a spotlight on the company’s $1.5 billion Personalis Inc. (NASDAQ:PSNL) deal.

Moderna uses Personalis’ sequencing platform to analyze tumor tissue and identify specific neoantigens needed to manufacture individualized doses.
