Tempus AI, Inc. insiders sold $221M in the past 12 months. How much of their stake is that?

Board members representing outside shareholders, reported separately: Theodore Leonsis. Details

Vested shares across all share classes, held directly and through trusts, LLCs and family members, as reported on SEC Forms 3, 4 and 5. Unvested awards and options are never counted as owned shares.

12 of 15 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (11 exactly, 1 with a minor or footnoted difference). For 3 we show sales but not holdings; the ! icon on their rows explains why. Percentages cover 12 of 15 officers and directors. Left out: David Epstein, Jennifer Doudna and Thomas Schoenherr (holdings couldn't be fully reconciled). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

Officer and director open-market sales: $221M across 3,476,143 shares. Plan status and stated purpose are separate questions, and a sale can have both.

Sales by month

Directors whose reported holdings sit mostly in an investment fund or a corporate shareholder they represent, not in their own name, with beneficial ownership disclaimed except for their own financial interest. Listed and sourced here; not part of the management totals or the answer line. Shares a fund hands to its own investors are distributions, not sales.

Not enough history to compare: fewer than three earlier years of filings.

Open-market sales (Form 4 code S) by people who were officers or directors, in split-adjusted shares. Earlier years include people who have since left. A sale that an outside holder also reports (a family trust, a fund) is counted with outside holders in every year. Shares, not dollars, are compared, so a change in the stock price doesn't look like a change in selling. Years the filings don't fully cover are shown but left out of the average.

All 232 Forms 3, 4 and 5 filed for Tempus AI, Inc. (SEC CIK 1717115) from Jun 13, 2024 to Sep 29, 2026, retrieved from SEC EDGAR on Oct 8, 2026. Prices are the ones reported in each filing, often weighted averages. 3 filings were left out because Tempus AI, Inc. filed them as an owner of another company's stock.

Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.

Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
