WEST FRASER AMENDS ITS BRITISH COLUMBIA OPERATING PLAN

VANCOUVER, BC, Aug. 9, 2022 /PRNewswire/ - West Fraser Timber Co. Ltd. ("West Fraser" or the "Company") (TSX and NYSE: WFG) announced today it is permanently curtailing approximately 170 million board feet of combined production at its Fraser Lake and Williams Lake sawmills and approximately 85 million square feet of plywood production at its Quesnel Plywood mill.  The curtailments will be realized through the elimination of one shift at each facility.

The reduction in capacity is expected to impact 77 positions at Fraser Lake Sawmill, 15 positions at Williams Lake Lumber, and 55 positions at Quesnel Plywood and will occur over the course of the fourth quarter of 2022.  The Company expects to mitigate the impact on effected employees by providing work opportunities at other West Fraser operations.

Access to available timber is an increasing challenge in British Columbia and ongoing transportation constraints have impaired the Company's ability to reliably access markets.  These capacity reductions are necessary to better align West Fraser's operating capacity with available timber and transport availability.

West Fraser is a diversified wood products company with more than 60 facilities in Canada, the United States, the United Kingdom, and Europe. From responsibly sourced and sustainably managed forest resources, the Company produces lumber, engineered wood products (OSB, LVL, MDF, plywood, and particleboard), pulp, newsprint, wood chips, other residuals, and renewable energy. West Fraser's products are used in home construction, repair and remodelling, industrial applications, papers, tissue, and box materials.
