Teradata Corporation Code of Conduct

To maintain the security, integrity, and the business purposes of our information technologies and comply with laws, regulations, privacy obligations, and contractual duties, we all need to take necessary actions to safeguard passwords and identification codes to prevent unauthorized access to Teradata, customer, and business partner information systems.

Teradata reserves the right to monitor your use of Teradata systems and resources, and the content of any messages transmitted or stored through or in its systems. This includes information that has been deleted by users or sent over Teradata networks. You should not expect privacy (beyond that required by applicable laws) when using email, the Internet, or other forms of electronic communications on Teradata, customer, or business partner computers or networks. Teradata expects and requires each of us to be respectful of the conditions and limitations that apply to use of Teradata resources and the resources of its customers and business partners.

None of the restrictions relating to social media or confidentiality of employee information are intended or should be interpreted as limiting an employee’s right to engage in legally protected concerted activity.

Insider Trading

We regularly have access to information that others may not have about Teradata and the companies with which we conduct or may propose to conduct business. This knowledge may include non-public information that might influence an investor to buy, sell, or otherwise trade in a company’s securities (including stocks and options of Teradata or other companies involved), such as non-public information about acquisitions, divestitures, management changes, or financial results or projections.

Insider trading is the illegal act of buying, selling, or otherwise trading in securities while in the possession of material non-public information about Teradata, its customers, its business partners, or others with which Teradata has or is considering a business relationship.

Insider trading is a serious violation of our Code, the Teradata Insider Trading Policy (see Corporate Management Policies CMP 922 and CMP 922Q). state and federal securities laws, and could subject the individuals involved to immediate termination and potential criminal prosecution.

“Tipping” is also a violation of our policies, Code, and securities laws, with the same consequences. Tipping occurs when you provide material non-public information to someone else, even inadvertently, and that person acts on the information, or tips others to act on the information to buy, sell, or otherwise trade in securities. Each of us must be careful not to disclose any non-public information about Teradata, our customers, our business partners, or others with which Teradata has or is considering a business relationship to family members, friends, or other third parties.

Under the Teradata Insider Trading Policy, certain associates will be treated as restricted insiders and automatically “blacked-out” from trading during certain periods. If you have questions or concerns about trading in securities while in possession of inside information or while serving in a restricted insider role, consult the Teradata Insider Trading Policy and, if still in doubt, contact the Law Department for more guidance before you trade.

External Company Communications

To help assure our reputation is effectively managed and protected, all communications with media outlets involving Teradata must be handled through the Teradata Public Relations/Communications organization. Similarly, all responses to subpoenas and governmental inquiries and inspection requests must be handled through the Teradata Law Department. And, all business and financial results disclosure must be made only when and as authorized under Teradata policies (see CMP 110) and by the Teradata Disclosures Committee. This helps us ensure the information we communicate or produce is consistent, accurate, and in line with Teradata policies and disclosure laws, regulations, and legal requirements.
