Tempus AI CEO sold shares 40 days before calling Q3 a record quarter
As seen on the 24/7 Wall St. homepage on November 2, 2026.
Q3 was another record quarter, as we delivered $411.5 million of revenue, led by accelerating unit growth of 32% in our oncology business and increasing momentum of 33% revenue growth in Data & Applications.
Lefkofsky sold shares on September 24, five and a half weeks before stepping up to call the quarter a record, so the Form 4 came while he already had a line of sight on results. The words and the trade point in opposite directions, and insider timing is now part of the story for anyone buying the growth narrative at a $13.4 billion market cap.

Eric P. Lefkofsky, CEO and Chairman of Tempus AI, filed a Form 4 disclosing a sale of shares on September 24, roughly five and a half weeks before he publicly declared Q3 a record quarter for the company. That sequence matters because the trade came while the quarter was already underway, meaning he had meaningful visibility into the business trajectory before the sale.
On the earnings call, Lefkofsky pointed to $411.5 million in Q3 revenue, 32% unit growth in the oncology business, and 33% revenue growth in the Data and Applications segment. All three figures were framed as accelerating momentum, language that sits in notable tension with an executive selling shares in the weeks before making those claims.

Insider sales are not inherently bearish. Executives sell for many reasons, from tax planning to portfolio diversification, and a single Form 4 is rarely the whole story. But timing is a legitimate input for investors trying to gauge how much conviction leadership has in its own growth narrative.
With Tempus AI carrying a $13.4 billion market cap, the stock is priced for continued acceleration. Anyone underwriting that valuation now has to weigh the record-quarter language against the direction of the CEO's own trade made 40 days earlier.
