Sylvamo and Riverdale mill supply agreement update

International Paper announced plans to convert the No. 16 paper machine at its Riverdale mill in
Selma, Alabama, to produce containerboard by the third quarter of 2026

• The mill currently supplies us with approximately 260,000 short tons of cutsize uncoated freesheet annually from the machine through a supply agreement.
• The Riverdale supply agreement is not part of our long-term strategy, and we have been planning for this conversion since our 2021 spinoff.
• We will support our customers throughout this transition.

We anticipate losing Riverdale volume when International Paper takes down No. 16 paper machine to begin the conversion to produce containerboard

• We have various options to mitigate impacts to our customers and are assessing which options are economically viable and work best under the evolving economic and tariff conditions
• We plan to optimize our mix to minimize the earnings impact, which may include redirecting volume to the U.S. from our mills in Brazil and Europe.
• Based on our current assumptions for optimizing operations, mix and paper supply, the Adj. EBITDA impact in 2026 from the loss of Riverdale volume is estimated to be ~$30 million, at current margins.
