WEST FRASER ANNOUNCES RENEWAL OF NORMAL COURSE ISSUER BID

The Toronto Stock Exchange (TSX) has accepted West Fraser Timber Co. Ltd.'s notice to renew its normal course issuer bid (NCIB). Under the renewed NCIB, West Fraser will be entitled to purchase up to 4,063,696 common shares of the company, representing approximately 5 per cent of the 81,273,936 shares issued and outstanding as at Feb. 13, 2023. The NCIB will commence on Feb. 27, 2023.

Purchases under the NCIB may be made through the facilities of the TSX, the New York Stock Exchange ("NYSE") and alternative trading systems in Canada and/or the United States, if eligible. Purchases of Shares under the NCIB may be made on the TSX, at the market price at the time of purchase in accordance with the rules and policies of the TSX, or on the NYSE in compliance with Rule 10b-18 under the United States Securities Exchange Act of 1934 (the "Exchange Act"). In addition, purchases may also be made by private agreement or under a specific share repurchase program pursuant to an issuer bid exemption order issued by a securities regulatory authority, in which event purchases will be at a discount to the prevailing market price.

The rules and policies of the TSX contain restrictions on the number of Shares that can be purchased under the NCIB, based on the average daily trading volumes on the TSX. Similarly, the safe harbor conditions of Rule 10b-18 under the Exchange Act impose certain limitations on the number of Shares that can be purchased on the NYSE each day. As a result of the restrictions, subject to certain exceptions for block purchases, the maximum number of Shares which can be purchased per day during the NCIB on the TSX is 57,476 based on 25% of the average daily trading volume on the TSX for the prior six months (being 229,907 Shares on the TSX). Subject to certain exceptions for block purchases, the maximum number of Shares which can be purchased per day on the NYSE is 25% of the average daily trading volume on NYSE for the four calendar weeks preceding the date of purchase. Subject to regulatory requirements, the actual number of Shares purchased and the timing of such purchases, if any, will be determined by West Fraser having regard to future price movements and other factors. All Shares purchased by West Fraser under the NCIB will be cancelled.

The NCIB will terminate on February 26, 2024 or earlier if the maximum number of Shares authorized for repurchase under the NCIB have been purchased. West Fraser reserves the right to terminate the NCIB earlier if it feels it is appropriate to do so.

West Fraser plans to enter into an automatic purchase plan with a broker which will enable West Fraser to provide standard instructions and purchase Shares on the open market during self-imposed black-out periods. Outside of these black-out periods, Shares may be purchased in accordance with management's discretion.

West Fraser's prior normal course issuer bid for the purchase of up to 10,194,000 Shares expired on February 22, 2023. In aggregate, West Fraser purchased a total of 10,194,00 Shares at a volume weighted average price of US$81.78 per Share, excluding brokerage fees, all of which purchases were made on the open market.
