On December 3, 2025, the Board of Directors (the “Board”) of the Company appointed Mark Barrenechea to serve as a member of the Board. Mr. Barrenechea will serve as a Class II director, whose term expires at the Company’s annual meeting of stockholders to be held in 2026, and until Mr. Barrenechea’s successor shall have been duly elected and qualified, or until Mr. Barrenechea’s earlier death, resignation, disqualification or removal. Mr. Barrenechea has not yet been appointed to any standing committees of the Board. The Company will file an amendment to this Form 8-K to disclose any such appointments after they are made.
Mr. Barrenechea served as the Chief Executive Officer and Chief Technology Officer of OpenText Corporation, an information management software products company, from January 2012 to August 2025. Prior to that, he served as the President and Chief Executive Officer of Silicon Graphics International Corporation, a computer hardware and software company, from 2006 to 2012.

In accordance with the Company’s amended and restated Outside Director Program, as described in the Company’s Definitive Proxy Statement for the 2025 Annual Meeting of Stockholders, dated May 14, 2025, Mr. Barrenechea is entitled to (i) an annual cash retainer of $50,000 for service on the Board, (ii) additional annual cash compensation for committee membership, in each case payable in quarterly arrears, prorated based on full calendar months served, and subject to Mr. Barrenechea’s continued service, (iii) an initial equity award with an initial grant date value of $400,000 (the “Initial Award”), and (iv) an annual equity award with an initial grant date value equal to $225,000 (the “Annual Award”). Mr. Barrenechea may elect to receive his cash fees in the form of restricted stock units pursuant to a written election in lieu of cash.
