FORWARD-LOOKING STATEMENTS
This Annual Report and the exhibits attached hereto include certain statements that constitute "forward-looking statements" under the provisions of the U.S. Private Securities Litigation Reform Act of 1995, Section 21E under the Exchange Act, Section 27A of the U.S. Securities Act of 1933, as amended, and forward-looking information within the meaning of applicable Canadian securities legislation. Actual results or events could differ materially from those set forth in, or implied by, the forward-looking statements and the related assumptions due to a variety of factors. Investors are referred to the cautionary notes entitled “Forward-Looking Statements” that are included in each of our 2023 AIF and 2023 Annual MD&A for a discussion of these forward-looking statements and the risks that impact these forward-looking statements. Investors are also referred to the risks described under the title “Risks and Uncertainties” in our 2023 Annual MD&A and in our 2023 AIF. This list of important factors affecting forward-looking statements is not exhaustive, and reference should be made to the other factors discussed in public filings with securities regulatory authorities, including the SEC. Accordingly, investors should exercise caution in relying upon forward-looking statements, and West Fraser undertakes no obligation to publicly update or revise any forward-looking statements, whether written or oral, to reflect subsequent events or circumstances except as required by applicable securities laws.
NOTE TO UNITED STATES READERS REGARDING DIFFERENCES
BETWEEN UNITED STATES AND CANADIAN REPORTING PRACTICES
West Fraser is permitted to prepare this Annual Report in accordance with Canadian disclosure requirements which require Canadian public companies to prepare financial statements in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board ("IFRS Accounting Standards"). Accordingly, the Company’s 2023 Audited Annual Financial Statements have been prepared in accordance with IFRS Accounting Standards. Therefore, West Fraser’s 2023 Audited Annual Financial Statements incorporated by reference in this Annual Report may not be comparable to financial statements prepared in accordance with US GAAP. Our Independent Registered Public Accounting Firm performs an audit of the consolidated financial statements in accordance with the standards of the



Public Company Accounting Oversight Board (United States) (the "PCAOB"). Our Independent Registered Public Accounting Firm is independent within the meaning of the Chartered Professional Accountants of British Columbia Code of Professional Conduct in addition to the auditor independence standards of the PCAOB and the SEC.
CONTROLS AND PROCEDURES
West Fraser is responsible for establishing and maintaining disclosure controls and procedures (as such term is defined in Rules 13a-15(e) of the Exchange Act) and internal control over financial reporting (as such term is defined in Rules 13a-15(f) of the Exchange Act).
Disclosure Controls and Procedures
Disclosure controls and procedures are defined in Rule 13a-15(e) of the Exchange Act to mean controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and includes, without limitation, controls and procedures designed to ensure that such information is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.
Our management, under the supervision and with the participation of our President and Chief Executive Officer (“CEO”) and the Senior Vice-President, Finance and Chief Financial Officer (“CFO”), has conducted an evaluation of our disclosure controls and procedures as of December 31, 2023. Based on this evaluation, management, under the supervision of our CEO and CFO, have concluded that our disclosure controls and procedures are effective as of December 31, 2023.
Management's Report on Internal Control over Financial Reporting
Management, under the supervision of the CEO and CFO, is responsible for establishing and maintaining adequate internal control over financial reporting to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external reporting purposes in accordance with IFRS Accounting Standards.
Management, under the supervision of the CEO and CFO, has assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2023 based on the criteria set forth in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on this assessment, management has concluded that the Company’s internal control over financial reporting was effective as of December 31, 2023. See "Management's Report on Internal Control over Financial Reporting", included in Exhibit 99.2 attached hereto which is incorporated by reference into this Annual Report.
We have excluded Spray Lake Sawmills (1980) Ltd. ("Spray Lake") from our assessment of internal control over financial reporting as at December 31, 2023 because it was acquired on November 17, 2023. Spray Lake’s contribution to our consolidated financial statements for the year ended December 31, 2023 was $5 million of sales, representing approximately 0.1% of consolidated sales, and $1 million of loss, representing 0.7% of consolidated loss. Additionally, assets attributed to Spray Lake’s assets were $134 million, representing approximately 1.4% of our total assets as at December 31, 2023.
Attestation Report of the Independent Registered Public Accounting Firm
The effectiveness of the Company’s internal control over financial reporting as of December 31, 2023 has been audited by PricewaterhouseCoopers LLP, the Company’s independent registered public accounting firm, as stated in their report which appears in Exhibit 99.2 to this Annual Report.
Changes in Internal Control over Financial Reporting
There has been no change in our internal control over financial reporting during the year ended December 31, 2023, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.



AUDIT COMMITTEE
Our Board of Directors (the "Board") has established a separately-designated independent Audit Committee (the "Audit Committee") of the Board in accordance with Section 3(a)(58)(A) of the Exchange Act for the purpose of overseeing our accounting and financial reporting processes and the audits of our annual financial statements. As at the date of this Annual Report, the Audit Committee was comprised of Gillian D. Winckler (Chair), Doyle Beneby, Eric Butler, Reid Carter, Colleen M. McMorrow and Ellis Ketcham Johnson. The Board has determined that each of the members of the Audit Committee is independent as determined under Rule 10A-3 of the Exchange Act and Section 303A.02 of the NYSE Listed Company Manual.
AUDIT COMMITTEE FINANCIAL EXPERT
Our Board has determined that Gillian D. Winckler, the Chair of the Audit Committee, is an audit committee financial expert (as that term is defined in Form 40-F) and is an independent director under applicable securities laws and the listing requirements of the NYSE.
The SEC has indicated that the designation of a person as an audit committee financial expert does not make such person an "expert" for any purpose, or impose any duties, obligations or liability on such person that are greater than those imposed on members of the Audit Committee and the Board who do not carry this designation, or affect the duties, obligations or liability of any other member of the Audit Committee or Board.
PRINCIPAL ACCOUNTING FEES AND SERVICES

1.Amounts represent actual and estimated fees related to the respective fiscal years noted. Amounts are billed and paid in Canadian dollars, British pound sterling, and Euros and have been translated to United States dollars using the average exchange rate for the respective years noted.

Audit fees relate to the integrated audit of our annual consolidated financial statements and the effectiveness of internal control over financial reporting as of December 31, 2023, reviews of our interim consolidated financial statements, and statutory audits of the financial statements of our subsidiaries.
Audit-Related Fees
Audit-related fees include employee benefit audits, services associated with registration statements, prospectuses, and other documents filed with securities regulators, and due diligence assistance.
Tax Fees
Tax fees relate to tax compliance, tax advice, and tax planning services.
All Other Fees
All other fees relate to fees in connection with translation services and limited assurance engagements relating to climate matters.



Audit Committee Pre-Approval Policies
The Audit Committee has adopted a policy that sets out the pre-approval requirements related to services to be performed by our independent auditors. The policy provides that the Audit Committee will annually review proposed audit, audit-related, tax and other services (to be submitted by the CFO and the independent auditor), and will provide general approval of described services, usually including specific maximum fee amounts.
Unless a service has received general pre-approval, it will require specific pre-approval by the Audit Committee. The Audit Committee is permitted to delegate pre-approval authority to any of its members. The Audit Committee reports on the pre-approval process to the full Board from time to time.
None of the services provided by PricewaterhouseCoopers LLP in the fiscal year ended December 31, 2023 were treated as exempt from pre-approval pursuant to the de minimis provision of paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.
OFF-BALANCE SHEET ARRANGEMENTS
West Fraser has not entered into any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues, expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors.
CONTRACTUAL OBLIGATIONS
The required tabular disclosure of contractual obligations is included in “Liquidity & Capital Resources – Contractual Obligations” of the 2023 Annual MD&A, filed as Exhibit 99.3 to this Annual Report, and incorporated herein by reference.
CODE OF ETHICS
West Fraser has adopted a “code of ethics” (as that term is defined in Form 40-F), entitled the West Fraser Code of Conduct that applies to all directors, officers and employees of West Fraser, including its CEO and CFO (the “Code of Ethics”). A copy of the Code of Ethics is posted on West Fraser’s website at https://www.westfraser.com/investors/corporate/code-conduct.
There were no waivers granted in respect of the Code of Ethics during the fiscal year ended December 31, 2023. If there is an amendment to the Code of Ethics, West Fraser intends to disclose any such amendment by posting such information on West Fraser's website. Unless and to the extent specifically referred to herein, the information on West Fraser's website shall not be deemed to be incorporated by reference in this Annual Report. Except for the Code of Ethics, and notwithstanding any reference to West Fraser's website or other websites in this Annual Report or in the documents incorporated by reference herein or attached as exhibits hereto, no information contained on the West Fraser's website or any other site shall be incorporated by reference in this Annual Report or in the documents incorporated by reference herein or attached as exhibits hereto.
NYSE CORPORATE GOVERNANCE
West Fraser’s common shares are listed for trading on NYSE. Section 303A.11 of the NYSE Listed Company Manual requires foreign private issuers, such as West Fraser, to disclose any significant ways in which their corporate governance practices differ from those followed by domestic companies under the NYSE listing standards. Section 310.00 of the NYSE Listed Company Manual generally requires that a listed company's by-laws provide for a quorum for any meeting of the holders of the company's common shares that is sufficiently high to ensure a representative vote. Pursuant to the NYSE corporate governance rules we, as a foreign private issuer, have elected to comply with practices that are permitted under Canadian law in lieu of the provisions of Section 310.00. West Fraser’s by-laws provide that the quorum requirement for meetings of shareholders is a minimum of 25% of the outstanding common shares in attendance at each meeting of shareholders, which is less than the 50% majority quorum requirement of many U.S. incorporated NYSE listed issuers.
Except as stated above we are in compliance with the rules generally applicable to U.S. domestic companies listed on the NYSE. We may in the future decide to use other foreign private issuer exemptions with respect to some of the other NYSE listing requirements. Following our home country governance practices, as opposed to the requirements that would otherwise apply to a company listed on the NYSE, may provide less protection than is accorded to investors under the NYSE listing requirements applicable to U.S. domestic issuers.



INTERACTIVE DATA FILE
West Fraser has submitted to the SEC an interactive data file in connection with this Annual Report.

CONSENT TO SERVICE OF PROCESS
West Fraser has previously filed an Appointment of Agent for Service of Process and Undertaking on Form F-X signed by the Company and its agent for service of process with respect to the class of securities in relation to which the obligation to file this Annual Report arises. Any change to the name or address of West Fraser’s agent for service shall be communicated promptly to the SEC by amendment to Form F-X referencing the file number of the Company.
