Value of insider-held stock

The insider holdings on file for this company add up to more shares than the company reports as outstanding. That is a sign the filed share counts and the company's own total are not on the same footing, so we do not put a dollar value on them.

What Tempus AI, Inc. reports
Revenue and net income below are for fiscal period FY2025, the period label carried by this company’s own annual XBRL filings to the SEC. Fiscal years do not line up between companies — one company’s FY2026 can cover much the same months as another’s FY2025 — so compare the periods, not just the numbers.

Where the employee count comes fromi
Headcount comes from Yahoo Finance, not from a filing. The date beside it is the day we retrieved the figure — it is not the date the company counted its staff, and Yahoo does not publish that date. Unlike the SEC filings behind the other figures on this page, this one carries no open licence, so we publish the number and nothing else from that source.
Insiders at Tempus AI, Inc.
Shares is what each person last reported holding here.i
Everyone below has filed at least one insider report against this company.
Value is that share count priced at the same closing price used everywhere else on this site. A row priced from only some of a person’s securities says so — we do not quietly present a partial sum as a complete one.
Rows are grouped by the role each person reports.i
The role comes from the relationship boxes a person ticks on their own insider filings — officer, director, ten per cent owner — not from anything we infer. Somebody who is both an officer and a director appears once, in the combined group, so the row count still matches the figure at the top of this page. Where no filing states a role we say so instead of guessing one.

Recent insider transactions
Of the 664 rows we hold,
0 are open-market
purchases and
535 open-market
sales (S) — the only codes we count as buying or selling.i
The rest — awards, shares withheld to pay tax, option exercises, gifts and so on — follow from an employment contract or a transfer arranged off-market, not from a decision to buy or sell, so counting them would turn this into a pay table.
A price of 0.00 is a real reported figure on gifts (G) and share awards (A) — not a gap in our data.

What a Form 4 isi
The report an officer, director or large shareholder must file after trading their own company’s stock.
Corporate ownership links — 2 filers hold a position, what this company owns
Who owns Tempus AI, Inc.
Each row is one filer naming this company.i
Funds, trusts and other companies file the same ownership forms that executives do. Everything below is taken from those filings, with the position exactly as the filing states it.
Do not add these figures together.
2 of the positions below were reported on filings shared by several filers at once.
Why the same shares appear twicei
On a joint filing every named filer is listed against the whole position, so the same block of stock appears under each name. Those rows are marked joint.

Being named on an ownership form is not the same as legal parent–subsidiary control.i
That relationship only holds if the filing says so. The map draws at most eight holdings per level, stops after two levels, and never doubles back on a name it has already passed through.
19 legal entities named in the subsidiary exhibit filed with this company’s most recent 10-K. .

Smaller entities are left out of the exhibit entirely. A short list here means a short exhibit — it does not mean the company owns nothing else. Nothing on this page is inferred: every name below is copied from the filing.

What counts as a subsidiaryi
A subsidiary is a separate legal entity this company controls; it is not the same thing as a brand, a division or an office. These entities do not file with the SEC in their own right, so there is no separate page to open for them.
