Dear Charles,

I am very pleased to extend you this offer of employment with Teradata Corporation and its affiliates (“Teradata” or the “Company”) as Interim Chief Financial Officer, based virtually, and reporting to me, subject to the conditions set forth below.

This letter outlines the key elements of your compensation and related arrangements, during the term of the interim Chief Financial Officer role, which are effective as of March 24, 2025. At the end of the interim assignment, your compensation will return to its current levels as the SVP and Chief Accounting Officer.

Base Salary: You shall receive a base salary of $530,000 on an annualized basis, less applicable taxes and withholdings, which would be paid on the Company’s normal bi-weekly payroll schedule and subject to change upon mutual agreement (other than a base salary reduction that is applied across-the-board to the Company’s Section 16 officers).

Management Incentive Plan: You will be eligible to participate in Teradata’s Management Incentive Plan (the “MIP”), a performance-based annual incentive program for executive officers.

The period of your eligibility under the MIP will begin March 24, 2025 and go through the term of the interim assignment (the “2025 MIP”). Your 2025 MIP will be pro-rated based on the time you are active as Interim Chief Financial Officer during 2025. Incentive awards are subject to discretionary adjustment by the Committee as outlined in the MIP and, if earned, are paid in the first calendar quarter following the program year. No MIP award is guaranteed, and you must be employed by Teradata on the date MIP awards are paid to be eligible to receive a MIP award.

The actual number of RSUs for your Special Equity Grant will be determined by dividing the target value by the preceding 20-day average of Teradata’s common stock prior to, but not including the effective date of the grant. The Special Equity Grant will be effective March 25, 2025, and be allocated 100% in RSUs, vesting in two (2) equal annual installments, which will vest on the respective anniversary dates of grant, in each case subject to your continued employment with Teradata and subject to the other terms and conditions set forth in your RSU equity award agreement. The Special Equity Grant will be governed by the terms and conditions of the Teradata 2023 Stock Incentive Plan, as amended (“Plan”) and your RSU equity award agreements, which you will be required to accept in connection with the award.
