Teradata Advances Board Refreshment Program

*Expects to Appoint Melissa Fisher to the Board*

*Enters into Cooperation Agreement with Lynrock Lake*

**SAN DIEGO, CA – February 10, 2026** – Teradata Corporation (NYSE: TDC) ("Teradata" or the "Company") today announced the following changes to its Board of Directors (the "Board") as part of the Board's ongoing refreshment program and in connection with a cooperation agreement (the "Agreement") with Lynrock Lake LP and certain related parties ("Lynrock Lake"):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Board expects to appoint Melissa Fisher to the Board as a Class I director no later than March 1, 2026, following the completion of customary onboarding procedures. Ms. Fisher is expected to be nominated for election at the Company's 2026 Annual Meeting of Stockholders (the "2026 Annual Meeting") with a term expiring at the 2029 Annual Meeting of Stockholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Board has an active search process underway to identify an additional independent director to join the Board following the 2026 Annual Meeting and will work with Lynrock Lake to select candidates for consideration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• As part of the Board's phased refreshment plan, one Class I director will retire and not stand for re-election at the 2026 Annual Meeting, and one Class II director will retire and not stand for re-election at the 2027 Annual Meeting of Stockholders.

Mike Gianoni, Chairman of the Board, said, "As part of our ongoing efforts to add new perspectives to the Board, we are pleased to welcome Melissa, whose experience within our sector and financial acumen will be additive to the initiatives already in progress. Continued Board refreshment is key to Teradata's long-term growth and value creation objectives and the changes announced today underscore this commitment."

Cynthia Paul, Chief Investment Officer and Chief Executive Officer of Lynrock Lake LP, commented, "We are pleased to have reached this collaborative outcome with Teradata. We firmly believe in the long-term value potential of Teradata and look forward to Melissa's contributions and further Board refreshment to advance the Company's strategic initiatives and enhance value for all shareholders."

Pursuant to the Agreement, Lynrock Lake has agreed to support the Board's full slate of directors at the 2026 Annual Meeting and also agreed to certain customary standstill, mutual non-disparagement, voting and other provisions. The Company will file the Agreement with the U.S. Securities and Exchange Commission (the "SEC") as an exhibit to a Current Report on Form 8-K.
