On June 14, 2018, the Board of Directors (the “Board”) of Teradata Corporation (the “Company” or “Teradata”) expanded the size of the Board from ten directors to eleven and elected Joanne Olsen as a director, effective as of June 15, 2018 (the “Effective Date”). Ms. Olsen was elected to Class III, with a term expiring at the Annual Meeting of Stockholders in 2019, or until such time as her successor is duly elected and qualified or as is otherwise provided in Teradata’s Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws.

The Board has determined that Ms. Olsen is independent under Teradata’s Board of Directors Corporate Governance Guidelines and the requirements of the New York Stock Exchange. There are no arrangements or understandings between Ms. Olsen and any other person pursuant to which she was elected as a director and there are no transactions involving Ms. Olsen that would be required to be reported under Item 404(a) of Regulation S-K. Ms. Olsen has not yet been named to a Board committee.

As of the Effective Date, Ms. Olsen will participate in certain non-employee director compensation arrangements under the Teradata Corporation Director Compensation Program, as amended (the “Program”). Under the terms of the Program, Ms. Olsen will receive a prorated annual retainer for the year ending on the date of the Company’s 2019 Annual Meeting in the amount of $50,000. Ms. Olsen will also receive equity grants under the terms of the Program, including an initial restricted share unit equity grant with a value of $75,000 and a prorated annual restricted share unit equity award with a value of $229,167.

On June 15, 2018, Teradata issued a press release that announced the election of Ms. Olsen, a copy of which is attached hereto as Exhibit 99.1 and incorporated herein by reference.
