IFP Interfor Corporation

INTERFOR CORPORATION (“Interfor” or the “Company”) (TSX: IFP) announced today that it will indefinitely curtail operations at its sawmills in Meldrim, Georgia and Summerville, South Carolina. These curtailments are in response to persistently weak lumber market conditions.

Log deliveries will be curtailed immediately, followed by an orderly wind-down of operations, which is expected to be completed by the end of the third quarter of 2024. Both sawmills produce kiln-dried Southern Yellow Pine dimensional lumber and have a combined annual capacity of 330 million board feet.

These indefinite curtailments will impact approximately 180 employees across both facilities. Interfor expects to mitigate some of the impact on affected employees by providing work opportunities at other Company operations, where possible.

The expected impact of these curtailments on production volume for the remainder of 2024 was included in the temporary curtailment guidance referenced in Interfor’s press release dated August 8, 2024. However, the indefinite nature of these curtailments means the impact on lumber production is likely to extend beyond 2024, based on facts and circumstances known today.

The Company will continue to monitor market conditions across all its operations and adjust its production plans accordingly.
