IFP Interfor Corporation

INTERFOR CORPORATION (“Interfor” or the “Company”) (TSX: IFP) announced plans to reduce its lumber production output in the first quarter of 2023 by at least 100 million board feet, or 8% of quarterly capacity, as economic conditions and market uncertainty continue to impact lumber demand. This temporary reduction in output is expected to be mostly concentrated outside of Interfor’s US South operating region.

The Company currently expects to resume its normal operating schedule in April 2023, but will closely monitor market conditions and adjust its production plans accordingly.
