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

As previously reported in International Paper Company's (the "Company") Current Report on Form 8-K filed on July 17, 2026 (the "Prior 8-K"), the Board of Directors (the "Board") of the Company, upon the recommendation of the Governance Committee, appointed Katherine Collins and Lori J. Ryerkerk to serve as independent directors of the Company effective October 1, 2026. At the time of the appointments, the Board had not yet determined the committee assignments for Ms. Collins and Ms. Ryerkerk.

Following further consideration, the Board, upon recommendation of the Governance Committee, on October 8, 2026, appointed Ms. Collins to serve as a member of the Audit and Finance Committee and the Governance Committee and appointed Ms. Ryerkerk to serve as a member of the Management Development and Compensation Committee and the Safety, Sustainability and Technology Committee.

As previously disclosed in the Prior 8-K, Directors Ahmet C. Dorduncu and Kathryn D. Sullivan notified the Board of their intention to retire from Board service effective December 31, 2026. Consistent with the Board's succession planning and transition process described in the Prior 8-K, Mr. Dorduncu and Ms. Sullivan will remain available to support an orderly transition by attending Audit and Finance and Safety, Technology and Sustainability committee meetings as invited guests until their respective retirement dates. During this transition period, they will serve solely in a non-voting capacity, will not be considered members of the committee for governance or quorum purposes, and will not possess any voting rights with respect to committee matters.

The information set forth in this Item 5.02 Current Report on Form 8-K updates and supplements the disclosure contained in the Prior 8-K regarding the committee assignments of Ms. Collins and Ms. Ryerkerk and the previously disclosed transition arrangements for Directors Dorduncu and Sullivan.
