Notes to Condensed Consolidated Financial Statements

For the three and nine months ended September 26, 2025 and September 27, 2024

(figures are in millions of United States dollars, except where indicated - unaudited)

1.Nature of operations

West Fraser Timber Co. Ltd. ("West Fraser", the “Company”, "we", "us" or "our") is a diversified wood products company with more than 50 facilities in Canada, the United States, the United Kingdom, and Europe, which promotes sustainable forest practices in its operations. The Company produces lumber, engineered wood products (OSB, LVL, MDF, plywood, and particleboard), pulp, newsprint, wood chips, and other residuals. West Fraser's products are used in home construction, repair and remodelling, industrial applications, papers and tissue. Our executive office is located at 885 West Georgia Street, Suite 1500, Vancouver, British Columbia. West Fraser was formed by articles of amalgamation under the Business Corporations Act (British Columbia) and is registered in British Columbia, Canada. Our Common shares are listed for trading on the Toronto Stock Exchange (“TSX”) and on the New York Stock Exchange (“NYSE”) under the symbol WFG.

2.Basis of presentation

These condensed consolidated financial statements have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS Accounting Standards”) applicable to the preparation of interim financial statements, under International Accounting Standard (“IAS”) 34, Interim Financial Reporting. These condensed consolidated financial statements use the same accounting policies as the most recent audited annual consolidated financial statements.

These condensed consolidated interim financial statements were authorized for issue by the Audit Committee of the Company’s Board of Directors on October 22, 2025. These condensed consolidated interim financial statements should be read in conjunction with our audited annual consolidated financial statements for the year ended December 31, 2024.

Our fiscal year is the calendar year ending December 31. Effective January 1, 2023, our fiscal quarters are the 13-week periods ending on the closest Friday to the end of March, June, and September with the fourth quarter ending December 31. References to the three months ended September 26, 2025 and the third quarter of 2025 relate to the 13-week period ended September 26, 2025 and references to the nine months ended September 26, 2025 relate to the 39-week period ended September 26, 2025.

Figures have been rounded to millions of dollars to reflect the accuracy of the underlying balances and as a result certain tables may not add due to rounding impacts.

Accounting standards issued but not yet applied

IFRS 18, Presentation and Disclosure in Financial Statements

In April 2024, the IASB issued IFRS 18, Presentation and Disclosure in Financial Statements ("IFRS 18"), which replaces IAS 1, Presentation of Financial Statements. IFRS 18 introduces new requirements to improve comparability in the reporting of financial performance to give investors a better basis for analyzing and comparing entities. The standard impacts the presentation of the financial statements and notes, in particular the income statement where entities will be required to present separate categories of income and expense for operating, investing, and financing activities with prescribed subtotals for each new category. IFRS 18 will also require management-defined performance measures to be explained and included in a separate note within the financial statements. IFRS 18 is effective for reporting periods beginning on or after January 1, 2027. We are currently assessing the impact of this amendment on our consolidated financial statements.

-5-

Amendments to the Classification and Measurement of Financial Instruments – Amendments to IFRS 9 and IFRS 7

On May 30, 2024, the IASB issued targeted amendments to IFRS 9 and IFRS 7 to respond to recent questions arising in practice, and to include new requirements not only for financial institutions but also for corporate entities. These amendments:

•clarify the date of recognition and derecognition of some financial assets and liabilities, with a new exception for some financial liabilities settled through an electronic cash transfer system;

•clarify and add further guidance for assessing whether a financial asset meets the solely payments of principal and interest (SPPI) criterion;

•add new disclosures for certain instruments with contractual terms that can change cash flows (such as some financial instruments with features linked to the achievement of environment, social and governance targets); and

•update the disclosures for equity instruments designated at fair value through other comprehensive income (FVOCI).

These amendments are effective for reporting periods beginning on or after January 1, 2026. We are currently assessing the impact of these amendments on our consolidated financial statements.

3. Seasonality of operations

Our operating results are subject to seasonal fluctuations that may impact quarter-to-quarter comparisons. Consequently, interim operating results may not proportionately reflect operating results for a full year.

Market demand varies seasonally, as home building activity and repair-and-remodelling work are generally stronger in the spring and summer months. Extreme weather conditions, including wildfires in Western Canada and hurricanes in the U.S. South, may periodically affect operations, including logging, manufacturing and transportation. Log inventory is typically built up in the northern regions of North America and Europe during the winter to sustain our lumber and EWP production during the second quarter when logging is curtailed due to wet and inaccessible land conditions. This inventory is generally consumed in the spring and summer months.

4. Inventories


	September 26,		December 31,
As at	2025		2024
Manufactured products	$	301	$	344
Logs and other raw materials	229		255
Materials and supplies	262		245
	$	792	$	844

Inventories at September 26, 2025 were subject to a valuation reserve of $70 million (June 27, 2025 - $55 million; December 31, 2024 - $18 million) to reflect net realizable value being lower than cost.

5. Operating loans and long-term debt

Credit Facility and Term Loan Renewals

In May 2025, we amended and restated our syndicated credit agreement providing for the renewal of our $1 billion revolving credit facility and extension of the facility's maturity from July 2028 to May 2030. The revolving credit facility is undrawn and was made available on substantially the same terms and conditions as our revolving credit facility prior to renewal. Additionally, under the amended and restated credit agreement, we increased and extended our $200 million term loan facility maturing July 2025. The modified term loan facility is for $300 million, matures May 2028, and is under substantially the same terms and conditions as our term loan facility prior to renewal.

The amendment of the term loan facility was determined to be a non-substantial modification and resulted in a nominal loss recognized in Finance income (expense), net.

Operating loans

As at September 26, 2025, our credit facilities consisted of the aforementioned $1 billion committed revolving credit facility which matures May 2030, a $20 million (£15 million) credit facility dedicated to our European operations, and an $11 million (CAD$15 million) demand line of credit dedicated to our jointly‑owned newsprint operation.

As at September 26, 2025, our revolving credit facilities were undrawn (December 31, 2024 - undrawn) and the associated deferred financing costs of $2 million (December 31, 2024 - $2 million) were recorded in other assets. Interest on the facilities is payable at floating rates based on Prime Rate Advances, US Base Rate Advances, Canadian Overnight Repo Rate Average (“CORRA”) Advances, or Secured Overnight Financing Rate (“SOFR”) Advances at our option.

In addition, we have credit facilities totalling $135 million (December 31, 2024 - $130 million) dedicated to letters of credit. Letters of credit in the amount of $33 million (December 31, 2024 - $36 million) were supported by these facilities.

All debt is unsecured except the $11 million (CAD$15 million) jointly-owned newsprint operation demand line of credit, which is secured by that joint operation’s current assets.

Long-term debt


	September 26,		December 31,
As at	2025		2024
Term loan due May 2028; floating interest rate	$	300	$	200
	300		200

Less: current portion	—		(200)
	$	300	$	—

The fair value of the long-term debt at September 26, 2025 was $300 million (December 31, 2024 - $200 million) based on rates available to us at the balance sheet date for long-term debt with similar terms and remaining maturities.

Interest rate swap contracts

On July 25, 2025, our interest rate swaps expired per their terms. These swaps had the effect of fixing the interest rate on $200 million of the term loan facility balance disclosed in the long-term debt table above to a weighted average interest rate of 2.61%, with the remaining $100 million being subject to a floating rate. The full $300 million balance of our term loan facility was subject to a floating interest rate between the expiry of these interest rate swaps and September 26, 2025.

The interest rate swap contracts were accounted for as a derivative, with the changes in their fair value included in other income or expense in our consolidated statements of earnings. For the three and nine months ended September 26, 2025, a nominal loss and a loss of $2 million respectively (three and nine months ended September 27, 2024 - a loss of $2 million and a loss of $3 million) were recognized in relation to the interest rate swap contracts.

Other		28		22

7. Retirement benefits

We maintain defined benefit and defined contribution pension plans covering most of our employees. The defined benefit plans generally do not require employee contributions and provide a guaranteed level of pension payable for life based either on length of service or on earnings and length of service, and in most cases do not increase after commencement of retirement. We also provide group life insurance, medical and extended health benefits to certain employee groups.

We used a discount rate assumption of 4.91% at September 26, 2025 (4.83% at December 31, 2024).

The actuarial gain (loss) on retirement benefits, included in other comprehensive earnings (loss), is as follows:


	Three Months Ended				Nine Months Ended

As at September 26, 2025, we held 20,850 Common shares as treasury shares for cancellation.

For the three and nine months ended September 26, 2025, we issued 4,700 Common shares under our share option plans (three and nine months ended September 27, 2024 - 5,240 and 12,550 Common shares).

-8-

Rights and restrictions of Common shares

The Common shares and Class B Common shares are equal in all respects, including the right to dividends, rights upon dissolution or winding up and the right to vote, except that each Class B Common share may at any time be exchanged for one Common share. Our Common shares are listed for trading on the TSX and NYSE under the symbol WFG, while our Class B Common shares are not. Certain circumstances or corporate transactions may require the approval of the holders of our Common shares and Class B Common shares on a separate class by class basis.

Share repurchases

On February 27, 2025, we renewed our normal course issuer bid (“2025 NCIB”) allowing us to acquire up to 3,868,177 Common shares for cancellation from March 3, 2025 until the expiry of the bid on March 2, 2026.

On February 27, 2024, we renewed our normal course issuer bid (“2024 NCIB”) allowing us to acquire up to 3,971,380 Common shares for cancellation from March 1, 2024 until the expiry of the bid on February 28, 2025.

For the three and nine months ended September 26, 2025, we repurchased for cancellation 553,467 and 1,531,128 Common shares respectively at an average price of $73.08 and $76.65 per share under our 2024 NCIB and 2025 NCIB programs. For the three and nine months ended September 27, 2024, we repurchased for cancellation 446,460 and 1,487,694 Common shares respectively at an average price of $78.67 and $78.83 per share under our 2023 NCIB and 2024 NCIB programs.

12. Tax recovery (provision)

The tax recovery (provision) differs from the amount that would have resulted from applying the B.C. statutory income tax rate to earnings (loss) before tax as follows:


	Three Months Ended				Nine Months Ended
	September 26, 2025		September 27, 2024		September 26, 2025		September 27, 2024
Income tax recovery at statutory rate of 27%	$	75	$	29	$	68	$	(22)
Rate differentials between jurisdictions and on specified activities	(4)		(4)		(2)		(2)
Non-taxable amounts including goodwill impairment	1		(3)		2		(2)
Impact of functional currency differences	4		—		4		—

Valuation allowance	(3)		—		1		—
Income tax settlement	—		—		(6)		—
Other	—		4		—		2
Tax recovery	$	73	$	26	$	66	$	(24)

In Q1-25, we entered into a settlement agreement with the Canada Revenue Agency in respect of certain prior tax periods. As a result, we recorded an additional tax provision of $6 million in Q1-25 and have received income tax refunds of $34 million on account of the matters in question.

13. Earnings (loss) per share

Basic earnings (loss) per share is calculated based on earnings (loss) available to Common shareholders, as set out below, using the weighted average number of Common shares and Class B Common shares outstanding.

Certain of our equity-based compensation plans may be settled in cash or Common shares at the holder’s option and for the purposes of calculating diluted earnings (loss) per share, the more dilutive of the cash-settled and equity-settled method is used, regardless of how the plan is accounted for. Plans that are accounted for using the cash-settled method will require adjustments to the numerator and denominator if the equity-settled method is determined to have a dilutive effect as compared to the cash-settled method.

The numerator under the equity-settled method is calculated based on earnings (loss) available to Common shareholders adjusted to remove the cash-settled equity-based compensation expense or recovery that has been charged or credited to earnings (loss) and deducting a notional charge using the equity‑settled method, as set out below. Adjustments to earnings (loss) are tax-effected as applicable. The denominator under the equity-settled method is calculated using the treasury stock method. Share options under the equity-settled method are considered dilutive when the average market price of our Common shares for the period exceeds the exercise price of the share option.

-10-

The equity-settled method was more dilutive for the three and nine months ended September 26, 2025 and an adjustment was required for the numerator and denominator. The cash-settled method was more dilutive for three and nine months ended September 27, 2024 and therefore no adjustment was required for the numerator and denominator.

A reconciliation of the numerator and denominator used for the purposes of calculating diluted earnings (loss) per share is as follows:


	Three Months Ended				Nine Months Ended
	September 26, 2025		September 27, 2024		September 26, 2025		September 27, 2024
Earnings (loss)

Net interest income (expense) on export duty deposits	(10)	1	—	13

1.Represents combined CVD and ADD cash deposit rate of 26.47% for August 12 to September 26, 2025, 16.50% for July 29 to August 11, 2025, 11.89% for January 1, 2025 to July 28, 2025, 11.89% for August 19 to September 27, 2024, and 9.25% for January 1, 2024 to August 18, 2024.

2.Represents adjustment to the annualized West Fraser estimated ADD rate of 4.00% for Q3-25 and YTD-25 and 4.42% for Q3-24 and YTD-24.

3.$32 million represents the duty expense attributable to the finalization of AR5 duty rates for the 2022 POI. The final CVD rate was 6.85% and the final ADD rate was 5.04% for AR5.

4.$67 million represents the duty expense attributable to the finalization of AR6 duty rates for the 2023 POI. The final CVD rate was 16.82% and the final ADD rate was 9.65% for AR6.

Countervailing (“CVD”) and antidumping (“ADD”) duty dispute

Additional details, including our accounting policy, can be found in note 26 - Countervailing (“CVD”) and antidumping (“ADD”) duty dispute of our audited annual consolidated financial statements for the year ended December 31, 2024.

Developments in CVD and ADD rates

We began paying CVD and ADD duties in 2017 based on the determination of duties payable by the United States Department of Commerce (“USDOC”). The CVD and ADD cash deposit rates are updated upon the finalization of the USDOC’s Administrative Review (“AR”) process for each Period of Inquiry (“POI”). On February 21, 2025, the USDOC initiated AR7 POI covering the 2024 calendar year. West Fraser was selected as a mandatory respondent, which will result in West Fraser continuing to be subject to a company-specific rate.

On July 29, 2025, the USDOC issued its final ADD rates and on August 12, 2025 the final CVD rates for the AR6 POI for January 1, 2023 to December 31, 2023. The final ADD rate of 9.65% and CVD rate of 16.82% resulted in the recognition of $67 million in incremental duty expense plus interest expense in earnings and an increase in export duty payable.

The Cash Deposit Rates and the West Fraser Estimated ADD Rate for the periods presented are as follows:


Effective dates for CVD	Cash Deposit Rate
AR7 POI1
January 1, 2024 – August 18, 2024	2.19	%
August 19, 2024 - December 31, 2024	6.85	%
AR8 POI2
January 1, 2025 – August 11, 2025	6.85	%
August 12, 2025 – September 26, 2025	16.82	%

1.The CVD rate for the AR7 POI will be adjusted when AR7 is complete and the USDOC finalizes the rate, which is not expected until 2026.

2.The CVD rate for the AR8 POI will be adjusted when AR8 is complete and the USDOC finalizes the rate, which is not expected until 2027.

AR8 POI2
January 1, 2025 - July 28, 2025	5.04	%	4.00	%
July 29, 2025 – September 26, 2025	9.65	%	4.00	%

1.The ADD rate for the AR7 POI will be adjusted when AR7 is complete and the USDOC finalizes the rate, which is not expected until 2026.

2.The ADD rate for the AR8 POI will be adjusted when AR8 is complete and the USDOC finalizes the rate, which is not expected until 2027.

Impact on balance sheet

Each POI is subject to independent administrative review by the USDOC, and the results of each POI may not be offset but the results within a POI in respect of ADD and CVD may be offset.

Appeals

Notwithstanding the deposit rates assigned under the investigations, our final liability for CVD and ADD will not be determined until each annual administration review process is complete and the related appeal processes are concluded.

On August 27, 2025, the Government of Canada, in consultation with affected Canadian provinces, industry and other concerned parties, submitted a Notice of Joint Motion for Voluntary Dismissal pertaining to the CUSMA Chapter 10 challenge of the AR2 ADD order. On September 10, 2025, the AR2 ADD CUSMA panel granted the motion for voluntary dismissal.

challenge of the AR1 ADD order. On September 17, 2025, the AR1 ADD CUSMA panel granted the motion for voluntary dismissal.

Through the withdrawal of the legal challenges, the rates for AR1 and AR2 ADD are finalized. In order for entries to be liquidated by U.S. Customs and Border Protection, both CVD and ADD legal challenges must be concluded. AR1 and AR2 CVD legal challenges are currently ongoing.

Tariffs

Canadian softwood lumber exports to the U.S. have been the subject of trade disputes and managed trade arrangements for several decades. Countervailing and antidumping duties have been in place since April 2017. Except for a two-day window in Q1-25, our wood products imported to the U.S. have not been subject to tariffs during the nine months ended September 26, 2025. See note 17 for additional developments in relation to tariffs subsequent to the reporting date.

16. Contingencies

We are subject to various investigations, claims and legal, regulatory and tax proceedings covering matters that arise in the ordinary course of business activities, including civil claims and lawsuits, regulatory examinations, investigations, audits and requests for information by governmental regulatory agencies and law enforcement authorities in various jurisdictions. Each of these matters is subject to uncertainties and it is possible that some of these matters may be resolved unfavourably. Certain conditions may exist as of the date the financial statements are issued, which may result in an additional loss. In the opinion of management none of these matters are expected to have a material effect on our results of operations or financial condition.

17. Subsequent events

On September 29, 2025, the U.S. administration issued a proclamation that imposed a tariff of 10% under Section 232 of the Trade Expansion Act of 1962 on imported softwood timber and lumber into the U.S., effective October 14, 2025. This tariff will be in addition to the existing softwood lumber duties applied to U.S. imports of Canadian lumber.
