International Paper has entered into an agreement to acquire North Pacific Paper Company (NORPAC), a portfolio company of One Rock Capital Partners, for $360 million.
NORPAC operates a paper manufacturing facility in Longview, Washington, employing approximately 500 people. The site runs three paper machines and produces about one million tons of containerboard and other paper grades annually, supplying packaging and industrial markets.
International Paper said the acquisition will complement its existing mill network by adding capacity in the U.S. West Coast region. The additional production is expected to improve system flexibility and support demand for lightweight and recycled containerboard grades used in corrugated packaging applications.
“This acquisition is a strong strategic fit for our business and supports our long-term value creation priorities,” said Tom Hamic, Executive Vice President and President, Packaging Solutions North America, International Paper.
“NORPAC is a high-quality business built on the strength of its first-rate management team and employees,” said Tony Lee, Co-Founder and Managing Partner of One Rock Capital Partners.
The Longview facility is expected to be integrated into International Paper’s broader operations following completion of the transaction. The company indicated that the integration process will focus on maintaining operational continuity while aligning production and supply capabilities with its existing system.
The deal reflects ongoing consolidation in the containerboard and packaging materials sector, where manufacturers are expanding regional production bases and strengthening supply chain coverage. The acquisition remains subject to regulatory approval and customary closing conditions.
Upon completion, the transaction will add North Pacific Paper Company’s production assets and workforce to International Paper’s portfolio, reinforcing its presence in North America. No additional financial details or timeline for closing were disclosed in the announcement. The company stated that updates will be provided following regulatory review and completion of the transaction process.
