Dear Stockholder:

The year 2024 marked a transformative chapter in our journey at RYAM, with remarkable achievements and strategic milestones that position us for an even brighter future. Your trust and support have been instrumental in this success.

RYAM delivered strong financial results in 2024, strengthening our balance sheet and enhancing our financial flexibility. We achieved significant debt reduction and maintained steady progress toward our long-term leverage targets.

These financial gains were complemented by strategic investments of $33 million in three key areas: biomaterials expansion, quick-return operational projects, and corporate systems. These investments reflect our commitment to operational excellence, disciplined growth, and innovation.

Our core High Purity Cellulose (HPC) business strengthened as we advanced our “Value over Volume” strategy, optimized our HPC sales mix, and benefited from improved industry supply-demand dynamics. This contributed to meaningful improvements in profitability and margin expansion.

Our biomaterials growth strategy also advanced in 2024, leveraging our global infrastructure to deliver renewable, high-value solutions. We attained significant milestones in key biomaterials projects, highlighted by the successful start-up and commercial operation of our France bioethanol plant. To further accelerate growth, we launched and capitalized RYAM BioNova S.A.S. on attractive terms.

Safety and sustainability remained central to RYAM’s mission. In 2024, we reduced our injury incident rate by 30%, and we published our 2023 Sustainability Report highlighting progress toward our greenhouse gas reduction targets along with our broader environmental commitments.

Thank you for your investment in and continued support of RYAM. As we enter 2025, RYAM is well-positioned to build on our successes, drive innovation, and achieve sustainable growth.
