(1) Mr. Cione served as the Chief Revenue Officer through April 5, 2024.
(2)Certain directors and officers terminated their existing Rule 10b5-1 Plans during the open window following Teradata's earnings release on February 12, 2024 for its 2023 year-end to avoid any negative appearance from selling Teradata securities in close proximity to the adverse stock market reaction to such earnings.
(3)Ms. Bramley had 72,480 net shares of the Company remaining under her Rule 10b5-1 Plan as of the date of termination of her Plan. Only the portion of these remaining shares necessary to satisfy sales of up to a total of $400,000 in the aggregate could have been sold if the Company’s stock price was at or above a specified price in the Rule 10b5-1 Plan during the open windows following the 2023 year-end and 2024 first quarter earnings calls.
(4)Mr. Cione had 36,196 net shares of the Company remaining under his 10b5-1 Plan as of the date of termination of his Plan. Such shares would have been sold under his Plan during specified periods if the Company’s stock price was at or above a specified price, each as in the Rule 10b5-1 Plan.
(5)Mr. Chou had 6,536 shares of the Company remaining under his Rule 10b5-1 Plan as of the date of termination of his Plan. Such shares would have been sold (i) at the market price of the Company’s stock on the day specified in the Plan and (ii) during specified periods if the Company’s stock price was at or above a specified price, each as in the Rule 10b5-1 Plan.
