DEREGISTRATION OF SECURITIES

This Post-Effective Amendment No. 1 (this "Post-Effective Amendment") amends the Registration Statement on Form S-8 (Registration No. 333-238886) (the "Registration Statement") previously filed with the Securities and Exchange Commission by Teradata Corporation, a Delaware corporation (the "Company"), with respect to 2,235,000 shares of common stock, $0.01 par value per share ("Common Stock"), of the Company that might be offered and sold pursuant to the Teradata New Employee Stock Inducement Plan, the Teradata Incentive Stock Purchase Plan and certain Restricted Share Unit Agreement Inducement Grants (collectively, the "Plans and Grants"). No further shares of the Company's Common Stock may be issued pursuant to the Plans and Grants and the offering registered under the Registration Statement therefore has been terminated. This Post-Effective Amendment is being filed pursuant to the undertaking contained in the Registration Statement to withdraw and remove from registration the 903,255 shares of Common Stock that remain unsold and unissued under the Plans and Grants previously registered by the Company pursuant to the Registration Statement.
