The cluster is modest in size but involves senior officers selling without a disclosed plan. Monitor for any subsequent Form 4 filings or 8-K disclosures that could explain the timing, such as a secondary offering or negative business update.
Price Chart
Executive Summary
Three Tempus AI insiders, including the Chief Accounting Officer and EVP/Chief Legal Officer, sold a total of $800K in shares over two days in mid-September.
