SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT The following table sets forth certain information regarding the ownership of our capital stock as of August 8, 2025 by:

| • |     | each named executive officer; |

| • |     | each of our directors; |

| • |     | our directors and executive officers as a group; and |

| • |     | each other person or entity known by us to own beneficially more than 5% of our Class A common stock and 
 Class B common stock (by number or by voting power).                                                     |

We have determined beneficial ownership in accordance with the rules and regulations of the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. Except as indicated by the footnotes below, we believe, based on information furnished to us, that the persons and entities named in the table below have sole voting and sole investment power with respect to all shares that they beneficially own, subject to applicable community property laws. The percentage ownership of Class A common stock and Class B common stock is based on 168,683,769 shares of Class A common stock and 5,043,789 shares of Class B common stock, respectively, outstanding as of August 8, 2025. In computing the number of shares beneficially owned by a person and the percentage ownership of such person, we deemed to be outstanding all shares subject to RSUs held by the person that would vest within 60 days of August 8, 2025. However, except as described above, we did not deem such shares outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the address for each beneficial owner listed in the table below is c/o Tempus AI, Inc., 600 West Chicago Avenue, Suite 510 Chicago, Illinois 60654.
