Segment Reporting [Abstract]  
Segments
15. Segments
As mentioned in Note 1—Nature of Operations and Basis of Presentation, beginning in the first quarter of 2026, the Company reorganized its segment structure and now operates in two segments:
•High Purity Cellulose: composed of the former segments of Cellulose Specialties, Cellulose Commodities and Biomaterials
•Paperboard & High Yield Pulp: composed of the former segments of Paperboard and High Yield Pulp
Corporate & Other consists primarily of senior management, accounting, information systems, human resources, treasury, tax and legal administrative functions that provide support services to the operating business units.
Prior period segment results have been recast to align with this new segment reporting structure.
The Company’s segment structure is determined based primarily on how its CODM reviews and evaluates Company operations. In January 2026, the Company’s Board of Directors appointed a new CEO and an analysis was performed to determine whether a change in CODM and/or reportable segments had occurred. The analysis identified the Company’s new CEO as the CODM and determined the two reportable segments listed above to be the level at which the CEO assesses performance and makes decisions regarding resource allocation. In April 2026, the new CEO resigned and the Board of Directors established an interim Office of the CEO composed of four existing RYAM executives. A new analysis determined that (i) the Office of the CEO is the new CODM and (ii) there has been no change in the approach to evaluating the business and therefore no change in reportable segments from those listed above.
The significant integration of the Company’s operations forms the basis of the CODM’s method of performance evaluation and resource allocation. At the Company’s HPC plants — Jesup, Fernandina and Tartas — fixed costs support the production and sale of all products across the specialties, commodities and biomaterials markets that the Company serves. Additionally, bioethanol production in France is dependent on feedstock from the Tartas HPC plant. Likewise, the Company’s paperboard and high yield pulp operations at Temiscaming are highly interconnected, with high yield pulp being used as feedstock for paperboard production and extensive shared site costs supporting the production of all products at the site. Given the integrated nature of these operations, the CODM assesses performance and allocates resources to maximize the profitability of the combined business units according to the optimal product mix of any given period.
The CODM uses “operating income (loss)” as a measure of segment profitability, predominantly within the monthly budgeting and forecasting process, where it reviews forecast and budget-to-actual variances to assess performance and inform its decisions on capital allocation within the Company.
Net sales by product line, by segment, were as follows:
