Separation of Chief Executive Officer On August 17, 2026, the Company announced that the Company and Christopher Kubasik, its Chairman and Chief Executive Officer (the “Executive”), mutually agreed to end the Executive’s employment with the Company effective immediately (the “Separation Date”). In connection with such departure, the Executive resigned as a member of the Company’s Board and all boards of the Company’s subsidiaries and affiliates. The Executive’s departure comes after an investigation conducted by the independent members of the Board, with the assistance of independent counsel. The Board determined that the Executive engaged in conduct that was not consistent with the values of the Company as outlined in its Code of Conduct. Such conduct did not involve, and has no impact on, the Company’s financial reporting, controls, customer relationships or operational performance, and the Executive’s resignation from the Company’s Board was not because of a disagreement with the Company on any matter relating to the Company’s operations, policies or practices. In connection with the Executive’s departure, the Company and the Executive entered into a Separation Agreement, dated as of August 16, 2026 (the “Separation Agreement”). Pursuant to the Separation Agreement, the Executive’s employment ended on the Separation Date and he resigned as a member of the Board and all boards of the Company’s subsidiaries and affiliates. The Executive will work with the Board to assist with an efficient transition of his duties and responsibilities. The Separation Agreement further provides that the Executive will be entitled to retain and exercise certain previously vested stock options granted to him under the Company’s equity incentive plans, but will not be entitled to any severance payments or benefits or accelerated vesting of any unvested equity incentive awards. The Separation Agreement also contains mutual releases of certain claims by each party against the other, as well as customary restrictive covenants, including confidentiality, non-disparagement, non-solicitation, no-hire, customer non-interference and non-competition covenants for specified periods following the Separation Date. The foregoing description of the Separation Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Separation Agreement, attached hereto as Exhibit 10.1 and incorporated herein by reference.
