Interfor announces incremental lumber production curtailments for Q4

INTERFOR (IFSPF) announced revised operating plans for the fourth quarter of 2025. Due to persistently weak market conditions and ongoing economic uncertainty, Interfor will further temporarily reduce lumber production across its operations in British Columbia, Ontario, the US Pacific Northwest and the US South. These curtailments are expected to reduce lumber production in the fourth quarter of 2025 by approximately 250M board feet, or 26%, as compared to the second quarter of 2025, which reflected a more normal operating stance. The curtailment volumes are approximately evenly split between Interfor’s Canadian and U.S. operations. Interfor produced 936M board feet of lumber in the second quarter of 2025 and approximately 910M board feet of lumber in the third quarter of 2025. These curtailments are an amendment to Interfor’s previously announced curtailments on September 4, 2025.
