05:40 PM EST, 11/06/2025 (MT Newswires) -- Interfor Corporation ( IFSPF ) said Thursday its third-quarter loss widened due to weak lumber pricing, log supply disruptions and higher export duty expenses

The company said it lost US$215.8 million, or US$4.19 per share, compared with a loss of US$105.7 million, or US$2.05 per share, a year earlier,.

Revenue was broadly flat at US$689.3 million, compared with US$692.7 million in the same quarter last year. Adjusted EBITDA was a loss of US$183.8 million, versus a loss of US$22.0 million in the prior-year period.

The company reported a lumber production of 912-million board feet, up from 904-million board feet a year earlier.

Interfor ( IFSPF ) noted that the newly imposed U.S. tariff measures are expected to pressure lumber exports and further weigh on margins. On September 29, U.S. President Trump issued a proclamation imposing a Section 232 tariff of 10% on all imports of softwood lumber into the U.S., including from Canada, which took effect on October 14, 2025. This tariff is in addition to the existing softwood lumber duties payable on Canadian lumber imported into the United States.

Interfor's ( IFSPF ) stock closed 0.38% up at C$7.89 on Toronto Stock Exchange on Thursday.

Additionally, West Fraser Timber ( WFG ) on Thursday announced that it will permanently close both its Augusta, Georgia, and 100 Mile House, British Columbia, lumber mills by the end of 2025 following an orderly wind-down. It said that the decision is the result of timber supply challenges and soft lumber markets.
