What does Tempus AI do?

Tempus AI is a health technology company founded in 2015. It is embedding AI into diagnostics to empower physicians and researchers to make personalized, data-driven decisions.

“The ability to deploy AI in precision medicine at scale has only recently become possible,” the company said in an SEC filing.

“Advances in cloud computing, imaging technologies, large language models, and low-cost molecular profiling, along with the digitization of vast amounts of healthcare data, have created a landscape that we believe is finally ripe for AI.”

Tempus AI’s recent rally could also be driven by the launch of its AI-enabled personal health concierge app, Olivia. The app organizes patients’ health data in one place and uses AI to offer practical recommendations.

Tempus AI went public on June 14, 2024, with its initial public offering priced at $37 a share.

The company has not yet turned a profit. It reported losses of $290 million and $214 million for 2022 and 2023, respectively.

On Jan. 13, Tempus AI posted preliminary revenue for Q4 and full-year 2024.

The company expects FY24 revenue to reach $693 million, representing approximately 30% growth year-over-year.

This falls short of Wall Street analysts’ expectations of $716.98 million and is slightly lower than the higher end of the company’s projections in November.

The company’s projected Q4 revenue of $200 million also falls short of the consensus estimate of $206.07 million.

Loop Capital lowered Tempus AI’s price target to $52 from $57 with a buy rating following the preliminary results, citing the company’s below-consensus Q4 revenue pre-announcement, thefly.com reported.

Loop adds that Tempus AI also did not provide formal profitability guidance other than that it expects a sequential improvement in adjusted EBITDA in Q4.

Cathie Wood is also buying Tempus AI

Cathie Wood, head of Ark Investment Management, has also bought Tempus AI stock. She began investing in the stock after its June 24 IPO and has made several big purchases recently.

This month, for example, her Ark funds purchased 186,532 Tempus AI shares on Jan. 17, 378,883 on Jan. 13, and 53,376 on Jan. 3.
