WEST FRASER ANNOUNCES INDEFINITE CURTAILMENT OF LAKE BUTLER SAWMILL

West Fraser Timber Co. Ltd. will indefinitely curtail its sawmill in Lake Butler, Fla., by the end of this month. Today's decision is the result of high fibre costs and soft lumber markets.

The indefinite curtailment of Lake Butler sawmill will impact approximately 130 employees and reduce West Fraser's United States lumber capacity by approximately 110 million board feet. West Fraser expects to mitigate the impact on affected employees by providing work opportunities at other company operations.

High fibre costs at Lake Butler and the current low-price commodity environment have impaired the ability to profitably operate the mill. The indefinite curtailment of Lake Butler sawmill better aligns the company's U.S. lumber capacity with demand.

West Fraser anticipates taking an impairment charge in the third quarter of 2024 associated with the announcement.
