A Tempus AI Director Sold Stock Four Days Before a 24% Rally. Here's What to Know

Nadja West, a director at Tempus AI, sold 3,000 shares for $161,700 on August 14 under a pre-established Rule 10b5-1 trading plan set up in May. Four days later, the stock rallied 24% following news that Moderna and Merck's cancer vaccine succeeded in late-stage trials. West retained 34,981 shares worth ~$1.8 million. The sale timing appears coincidental as it was scheduled months in advance, and the company reported strong Q2 results with 22% revenue growth and its first GAAP profit.
