International Paper Company has finalized the committee assignments for two directors who recently joined its board. In a Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission on October 8, 2026, the company detailed these governance updates and reiterated the transition plans for two outgoing directors.

The board appointed Katherine Collins and Lori J. Ryerkerk as independent directors effective October 1, 2026. This appointment was previously disclosed in a Current Report on Form 8-K filed on July 17, 2026, following a recommendation from the company's Governance Committee. At the time of their initial appointment, the board had not yet determined which committees each director would join.

Following further consideration, the board acted on the Governance Committee's recommendation to place the new members on specific panels. Ms. Collins will serve as a member of both the Audit and Finance Committee and the Governance Committee. Ms. Ryerkerk will join the Management Development and Compensation Committee and the Safety, Sustainability and Technology Committee.

The filing also restates details regarding the retirement of directors Ahmet C. Dorduncu and Kathryn D. Sullivan. Both notified the board of their intention to retire from board service effective December 31, 2026. This information was part of the disclosure in the July 17, 2026 report.

As part of the company's succession planning and transition process, Mr. Dorduncu and Ms. Sullivan will remain available to support an orderly transition until their retirement dates. They will attend meetings of the Audit and Finance Committee and the Safety, Technology and Sustainability Committee as invited guests. During this period, they will serve solely in a non-voting capacity.

The company specified that the retiring directors will not be considered members of these committees for governance or quorum purposes. They will not possess voting rights with respect to any committee matters during this transition period.

The Form 8-K filing serves to update and supplement the prior disclosure regarding the committee assignments for Ms. Collins and Ms. Ryerkerk, as well as the transition arrangements for Mr. Dorduncu and Ms. Sullivan.
