Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

At the Annual Meeting of Stockholders of Arrowhead Pharmaceuticals, Inc. (the “Company”) held on March 17, 2022 (the “2022 Annual Meeting”), Michael S. Perry, D.V.M., Mauro Ferrari, Ph.D. and William Waddill (each, an “Affected Director”, and together, the “Affected Directors”) did not receive a majority of the votes cast on their respective re-election to the Company’s Board of Directors (the “Board”). In accordance with the Company’s Director Resignation Policy, each Affected Director offered to resign from the Board, and the Nominating Committee (the “Committee”) considered each such Affected Director’s offer of resignation and made a recommendation to the Board whether to accept or reject it. None of the Affected Directors participated in the proceedings of either the Committee or the Board with respect to any of the Affected Directors’ offers of resignation.

The Committee determined that concerns about the Company’s executive compensation programs were the primary apparent reasons for the Affected Directors’ re-election voting outcomes. The Committee unanimously determined to recommend to the Board to reject the offer of resignation from each Affected Directors. In making its recommendation, the Committee considered (i) the apparent reasons why each Affected Director did not receive a majority of votes cast in favor of their election as director, (ii) the tenure and qualifications of each Affected Director, (iii) the past and expected future contributions to the Board of each Affected Director, (iv) the composition of the Board, including the mix of skills, attributes and diversity of experience and viewpoints provided to the Company and (v) available alternatives to satisfy the reasons why each Affected Director did not receive a majority of votes cast in favor of their election as director.

After the Committee’s meeting, the Board considered and reviewed the Committee’s recommendation. The Board considered the apparent circumstances relevant to the stockholder vote on each Affected Director’s re-election and alternatives for responding to those apparent concerns. Following its discussion, the Board accepted the recommendation of the Committee and voted unanimously to reject each Affected Director’s offer of resignation. The Affected Directors will continue their service on the Board until the Company’s 2023 Annual Meeting of Stockholders or until their successor is elected and qualified.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
