Item 8.01 Other Events. On August 18, 2026, consistent with its thoughtful long-term Board leadership succession planning process, the Board of Directors (the “Board”) of Avery Dennison Corporation, a Delaware corporation (the “Company”), unanimously elected William Wagner as independent Board Chair, effective September 1, 2026, to serve in such capacity for the remainder of the one-year term ending at the 2027 Annual Meeting of Stockholders (the “Annual Meeting”). Mitchell Butier will continue to serve as non-executive Chairman through August 31, 2026 and as a non-independent member of the Board for the remainder of the one-year term ending at the Annual Meeting. Mr. Wagner has served as an independent member of the Board since October 2022, and currently serves as Chair of the Governance Committee and the Cybersecurity Committee. The Board previously determined that Mr. Wagner is independent under New York Stock Exchange listing standards such that a Lead Independent Director is no longer required under the Company’s Corporate Governance Guidelines. As a result, Patrick Siewert will cease serving as Lead Independent Director on August 31, 2026 and continue to serve as an independent member of the Board for the remainder of the one-year term ending at the Annual Meeting. Also on August 18, 2026, in light of the time commitments associated with Mr. Wagner’s role as independent Board Chair and his continuing service as Chair of the Cybersecurity Committee, the Board appointed Mr. Siewert, who currently serves as a member of the Governance Committee, to replace Mr. Wagner as its Chair, effective September 1, 2026, to serve in such capacity for the remainder of the one-year term ending at the Annual Meeting. Mr. Wagner will continue to serve in such capacity through August 31, 2026 and as a member of the Committee for the remainder of the one-year term ending at the Annual Meeting. SIGNATURES 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 hereunto duly authorized.
