MAGNITE, INC.

While Board members benefit from service on the boards of other companies and such service is encouraged, under the Corporate Governance Guidelines, directors are expected to limit the number of other boards on which they serve so as not to interfere with their service as a director of the Company. In this regard, the Company has adopted specific limits on the number of other public company boards upon which a director may sit. Ordinarily, directors may not serve on the boards of more than three other public companies in addition to the Company’s board and the CEO and directors who are executive officers of public companies may not serve on the board of more than one other public company in addition to the Company’s board. As part of the annual director nomination process, the nominating and governance committee considers directors’ adherence to these expectations, and directors are expected to notify and consult with the nominating and governance committee before accepting a seat on the board of another organization.
