Chair of the Board

Dear Stockholder:

2025 was a challenging year in which RYAM’s overall financial performance fell well short of the Board’s expectations. We did not deliver the level of earnings or cash generation necessary to create consistent stockholder value. Restoring sustainable profitability and positive cash flow is our immediate priority.

Throughout the year, the Board intensified its oversight of operating execution, cost discipline and capital allocation. We reviewed performance across each business segment, evaluated structural cost opportunities and heightened our focus on liquidity. While market conditions and operational disruptions weighed on results, we expect measurable improvement in operating reliability, cost performance and cash generation in 2026.

To sharpen accountability and reinforce our focus on financial performance, the Board approved a 2026 annual incentive program tied exclusively to EBITDA and free cash flow. Management incentives must reflect the outcomes that matter most to stockholders, and we have structured the program accordingly. This emphasis on disciplined financial performance is also reflected in the design of our long-term incentive program.

In late 2025, as part of the Board’s structured succession planning process, De Lyle W. Bloomquist and the Board mutually agreed that the time was appropriate to transition leadership. Succession planning is a regular component of the Board’s oversight responsibilities, and we had been engaged in ongoing discussions regarding leadership transition timing well in advance of this decision. Following that process, the Board appointed Scott M. Sutton as President and Chief Executive Officer, effective January 2026.

Scott brings significant operating and capital allocation experience in specialty materials businesses. His disciplined, execution-focused leadership is well aligned with RYAM’s current priorities. We thank De Lyle for his leadership and for his partnership in ensuring a thoughtful and orderly transition.

Looking ahead, the Board supports management’s focus on:

Restoring positive free cash flow;

Strengthening competitive positioning in Cellulose Specialties;

Improving reliability and cost performance across operations; and

Maintaining disciplined capital spending and deleveraging.

We continue to evaluate and enhance our governance framework. This year, we are again asking stockholders to approve proposals to declassify the Board and eliminate certain supermajority voting provisions. We believe these changes will strengthen accountability and align our governance structure with prevailing market standards.

Stockholder confidence is earned through consistent execution and financial discipline. The Board remains actively engaged in overseeing management’s performance and ensuring that the actions underway position RYAM for stronger and more sustainable results.

On behalf of the Board of Directors, thank you for your continued investment in RYAM.

Sincerely,

LISA M. PALUMBO
