The undersigned stockholder of Teradata Corporation, a Delaware corporation (“Teradata” or the “Company”), hereby appoints Stephen McMillan, Mark Culhane and Margaret A. Treese, and each of them, proxies, with full power of substitution, to vote all shares of common stock of Teradata that the undersigned is entitled to vote at Teradata’s Virtual Annual Meeting of Stockholders to be held at www.virtualshareholdermeeting.com/TDC2021 (or at any alternate location and/or by means of communication determined by or on behalf of the Board of Directors) on May 4, 2021, and at any postponement or adjournment thereof, in the manner indicated on the reverse side and in such proxyholders’ sole discretion, upon any matter that may properly come before the meeting, or any postponement or adjournment thereof, including to vote for the election of a substitute nominee for director as such proxyholders may select in the event any nominee named on this proxy card is unable to serve. This proxy card also provides voting instructions to the trustee of the Teradata Corporation Savings Plan, the Company’s 401(k) plan (the “Teradata Savings Plan”) and to the trustees and administrators of other plans, with regard to shares of Teradata common stock the undersigned may hold under such plans for which the undersigned is entitled to vote at said meeting to the extent permitted by such plans and their trustees and administrators. By executing this proxy card, the undersigned acknowledges receipt from the Company of the Notice of the 2021 Annual Meeting of Stockholders and accompanying Proxy Statement and hereby revokes any previously granted proxy that relates to the aforementioned Annual Meeting.

The proxyholders or the trustees and administrators of the plans, as the case may be, will vote the shares in accordance with the directions on this proxy card. If you do not indicate your choices on this proxy card, the proxyholders will vote the shares in accordance with the directors’ recommendations.
