What this transaction means for investors
Polovin's sale is a routine sell-to-cover on a 10b5-1 plan he set up back in August 2025, executing on schedule the same week Tempus stock happened to explode, which says nothing about his read on the company.
The more useful question, and the one investors should be watching for, is whether Tempus is worth buying after the swing it just had. The stock is down roughly 10% over the past year, but it's rallied about 75% since late last month, and even after that run, it's still sitting something like 30% below its all-time high near $104. Notably, the staggering run higher this past week wasn't driven by anything Tempus itself announced. It came from a Moderna and Merck cancer vaccine trial hitting its endpoints, which validates the genomic sequencing technology behind Tempus's pending $1.5 billion Personalis deal. The business backed that up with real numbers too, revenue up 22% to $382.5 million last quarter and its first GAAP profit, a quarter CEO Eric Lefkofsky called "another exceptional quarter for us." Whether that combination justifies the current price, or whether the rally has already priced in more than one trial readout confirms, is the real debate here rather than Polovin's tax bill.
