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 July 23, 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 June 27, 2025 and the second quarter of 2025 relate to the 13-week period ended June 27, 2025 and references to the six months ended June 27, 2025 relate to the 26-week period ended June 27, 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.

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.

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.

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.

Inventories at June 27, 2025 were subject to a valuation reserve of $55 million (March 28, 2025 - $13 million; December 31, 2024 - $18 million) to reflect net realizable value being lower than cost.

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, net.

As at June 27, 2025, our credit facilities consisted of the aforementioned $1 billion committed revolving credit facility which matures May 2030, $25 million of uncommitted revolving credit facilities available to our U.S. subsidiaries, 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.

The fair value of the long-term debt at June 27, 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.

We have interest rate swap contracts expiring July 25, 2025 that have the effect of fixing the interest rate on $200 million of the term loan facility balance disclosed in the long-term debt table above, with the remaining $100 million being subject to a floating rate. In January 2024, these interest rate swaps were amended to extend their maturity from August 2024 to July 2025. Following this amendment, the weighted average fixed interest rate payable under the contract was 2.61% (previously 0.91%).

The interest rate swap contracts are 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 six months ended June 27, 2025, a loss of $1 million and a loss of $2 million (three and six months ended June 28, 2024 - a loss of $1 million and a loss of $1 million) was recognized in relation to the interest rate swap contracts. The fair value of the interest rate swap contracts at June 27, 2025 was a nominal asset (December 31, 2024 - asset of $2 million).

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 4.92% at June 27, 2025 (4.83% at December 31, 2024).

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

400,000,000 Common shares, without par value

20,000,000 Class B Common shares, without par value

10,000,000 Preferred shares, issuable in series, without par value

As at June 27, 2025, we held 16,110 Common shares as treasury shares for cancellation.

For the three and six months ended June 27, 2025, we issued 4,700 Common shares under our share option plans (three and six months ended June 28, 2024 - 310 and 7,310 Common shares).

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 six months ended June 27, 2025, we repurchased for cancellation 448,001 and 977,661 Common shares respectively at an average price of $74.36 and $78.68 per share under our 2024 NCIB and 2025 NCIB programs. For the three and six months ended June 28, 2024, we repurchased for cancellation 935,568 and 1,041,234 respectively Common shares at an average price of $78.85 and $78.90 per share under our 2023 NCIB and 2024 NCIB programs.

In the six months ended June 28, 2024, we recorded an impairment reversal of $1 million in relation to the sale of the Hinton pulp mill and an impairment loss of $4 million in relation to the sale of the Quesnel River Pulp mill and Slave Lake Pulp mill.

In addition, in the six months ended June 28, 2024, we recorded restructuring and impairment charges of $12 million associated with the announcement of the permanent closure of our Fraser Lake lumber mill and the permanent closure of our lumber mill in Maxville, Florida and the indefinite curtailment of operations at our lumber mill in Huttig, Arkansas.

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:

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.

The equity-settled method was more dilutive for the three and six months ended June 27, 2025 and the three and six months ended June 28, 2024 , and an adjustment was required for the numerator and denominator for these periods.

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

The geographic distribution of external sales based on the location of product delivery is as follows:

The following table summarizes the impact of export duties, net, and tariffs in our earnings statement:

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.

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.

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

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.

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.

The following table reconciles our cash deposits paid during the period to the amount recorded in our earnings statement:

1.Represents combined CVD and ADD cash deposit rate of 11.89% for January 1, 2025 to June 27, 2025 and 9.25% for January 1, 2024 to June 28, 2024.

2.No adjustments were recorded as the West Fraser Estimated ADD rate of 5.04% for Q2-25 and YTD-25 and 7.06% for Q2-24 and YTD-24 equaled the cash deposit rate.

As of June 27, 2025, our export duties paid and payable on deposit with the USDOC were $939 million.

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.

Export duty deposits receivable is represented by:

Export duties payable is represented by:

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.

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. A Section 232 investigation by the U.S. Secretary of Commerce is ongoing to determine the effects on national security of imports of timber, lumber and their derivative products.

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.

This discussion and analysis by management (“MD&A”) of West Fraser Timber Co. Ltd.’s (“West Fraser”, the “Company”, “we”, “us”, or “our”) financial performance for the three and six months ended June 27, 2025 should be read in conjunction with: (i) our unaudited condensed consolidated interim financial statements and accompanying notes for the three and six months ended June 27, 2025 (“Interim Financial Statements”); (ii) our audited annual consolidated financial statements and accompanying notes for the year ended December 31, 2024 (“Annual Financial Statements”), which have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board ("IFRS Accounting Standards"); and (iii) our related 2024 annual MD&A (“Annual MD&A”).

West Fraser is a diversified wood products company with facilities in Canada, the U.S., the U.K. and Europe, manufacturing, selling, marketing and distributing lumber, engineered wood products (OSB, LVL, MDF, plywood, particleboard), pulp, newsprint, wood chips and other residuals. As at June 27, 2025, our business is comprised of 32 lumber mills, 15 OSB facilities, 3 plywood facilities, 3 MDF facilities, 1 particleboard facility, 1 LVL facility, 1 veneer facility, and 2 pulp and paper mills.

Our goal at West Fraser is to generate strong financial results through the business cycle, supported by robust product and geographic diversity, and relying on our committed workforce, the quality of our assets and our well-established people and culture. This culture emphasizes cost control in all aspects of the business and operating in a responsible, sustainable, financially conservative and prudent manner.

The North American wood products industry is cyclical and periodically faces difficult market conditions. Our earnings are sensitive to changes in world economic conditions, primarily those in North America, Asia and Europe and particularly to the U.S. housing market for new construction and repair and renovation spending. Most of our revenues are from sales of commodity products for which prices are sensitive to variations in supply and demand. As many of our costs are denominated in Canadian dollars, British pounds sterling and Euros, exchange rate fluctuations of the Canadian dollar, British pound sterling and Euro against the United States dollar can and are anticipated to be a significant source of earnings volatility for us.

We believe that maintaining a strong balance sheet and liquidity profile, along with our investment-grade issuer rating, enables us to execute a balanced capital allocation strategy. Our goal is to reinvest in our operations across all market cycles to strategically enhance productivity, product mix, and capacity and to maintain a leading cost position. We believe that a strong balance sheet also provides the financial flexibility to capitalize on growth opportunities, including the pursuit of opportunistic acquisitions and larger-scale strategic growth initiatives, and is a key tool in managing our business over the long term including returning capital to shareholders.

In North America, new home construction activity in the U.S. is a significant driver of lumber and OSB demand. According to the U.S. Census Bureau, the seasonally adjusted annualized rate of U.S. housing starts averaged 1.32 million units in June 2025, with permits issued averaging 1.40 million units. In comparison, U.S. housing starts were 1.37 million units in the full year 2024 and 1.42 million units in 2023. New housing construction has recently shown signs of further slowing as consumers continue to manage an environment of relatively high mortgage rates and housing affordability challenges. Conversely, existing home sales have improved moderately from recent depressed levels but remain near historic lows, owing largely to the lock-in effect with U.S. mortgages. Over the longer term, a large cohort of the population entering the typical home-buying age demographic are expected to support core demand for home construction and resale activity. Further, the U.S. central bank has cut its key lending rate a total of 100 bps since September 2024, which is directionally supportive for housing market demand. However, actual bond yields have failed to ease in-line with these rate cuts. Notwithstanding these factors, should the economy and employment slow more meaningfully, interest rates remain higher for longer or housing prices not adjust sufficiently lower to offset relatively elevated mortgage rates, housing affordability could continue to be adversely impacted, reducing near-term demand for new home construction and thus near-term demand for our wood-based building products.

In the second quarter, demand for our products used in repair and remodelling applications continued to be subdued. While there is risk that historically low rates of existing home sales will keep downward pressure on short-term repair and remodelling demand, over the medium and longer term, an aging housing stock and stabilization of inflation and interest rates are expected to stimulate renovation and repair spending that supports growth in lumber, plywood and OSB demand.

Regarding lumber supply fundamentals, several new capacity announcements in the U.S. South in recent years have not translated into an increase in overall North American supply. Rather, a significant offset to these new projects has been the capacity contraction within other key lumber producing regions of North America, including in the U.S. South where costs are generally lower but are also varied and depend on fibre supply, mill modernization levels, sawmill residuals disposition markets and labour reliability. In particular, the U.S. South has seen a number of announcements in recent quarters of mills in the region being permanently or indefinitely curtailed. It is also noteworthy that due to lengthy lumber supply chains, particularly for SPF products being transported by rail from Western Canada, the impact of facility closures in that region can take several weeks or months before the supply effects are realized by the industry. Lower demand from offshore markets for North American lumber is also a continuing factor, resulting in more domestically produced lumber remaining in the continent. Imports of lumber from Europe remain below the elevated levels experienced in early 2023. However, should these imports head materially higher again, the rebalancing of supply and demand for lumber products in North America could experience an even further extended time to recovery.

A number of OSB mill greenfield and re-start projects have been announced in recent years. While some of the announced greenfield projects are apt to be completed and begin production over the near to medium term, we continue to see meaningful constraints to significant new available OSB supply in the near term, including typical mill start-up curves. However, should new OSB supply come online in excess of demand requirements, OSB markets may experience a period of oversupply.

According to industry data, from 2020 through 2024 approximately 25% of U.S. lumber consumption and 28% of U.S. OSB consumption was supplied by Canadian mills. However, rising duties, tariffs and a Section 232 investigation currently underway by the U.S. Department of Commerce have created an environment of heightened financial uncertainty for Canadian-based manufacturing of lumber, OSB and other wood-based building products.

If Canadian exports to the U.S. are constrained because of these or any other factors, the supply of these products may fall short of U.S. demand levels over the near to medium term.

Refer to the discussion in our 2024 Annual MD&A under "Risks and Uncertainties - Trade Restrictions" as supplemented in the discussion in the Q1-25 MD&A under "Risks and Uncertainties" for discussion of risks associated with the aforementioned tariffs and possible actions resulting from the Section 232 investigation.

1.This is a non-GAAP financial measure. Refer to the “Non-GAAP and Other Specified Financial Measures” section of this document for more information on this measure.

Sales and earnings decreased from Q3-23 to Q4-23 due primarily to decreases in lumber and OSB pricing, higher export duties, and impairment charges related to announced facility closures and curtailments in our lumber segment. Sales and earnings improved in Q1-24 and Q2-24 due primarily to improvements in OSB pricing and lower impairment charges, partially offset by lower lumber pricing. Sales and earnings decreased in Q3-24 due primarily to lower OSB and lumber pricing and, earnings improved in Q4-24 as product pricing improved across all product segments, offset in part by lower OSB shipment volumes, higher costs, major maintenance downtime in the pulp & paper segment, and impairment charges related to goodwill in our Europe EWP segment. Sales and earnings improved in Q1-25 due primarily to higher lumber pricing, lower costs, and the non-recurrence of major maintenance in the pulp & paper segment and impairment charges in the Europe EWP segment. Sales increased from Q1-25 to Q2-25 primarily due to higher shipments in our lumber and NA EWP segments, offset in part by lower lumber and OSB pricing. Earnings decreased from Q1-25 to Q2-25 due primarily to the impact of lower product pricing, inventory write-downs, and higher fibre costs, offset in part by lower tax expense.

1.This is a non-GAAP financial measure. Refer to the “Non-GAAP and Other Specified Financial Measures” section of this document for more information on this measure.

Lumber sales increased from Q1-25 due to higher shipment volumes, offset by lower product pricing. Lumber sales increased from Q2-24 and YTD-24 due to higher product pricing, offset in part by lower shipment volumes.

The overall price variance resulted in a decrease in operating earnings and Adjusted EBITDA of $17 million compared to Q1-25, an increase of $85 million compared to Q2-24, and an increase of $144 million compared to YTD-24.

SPF shipment volumes increased from Q1-25 due to higher production volumes, discussed further in the section below. SPF shipment volumes decreased from Q2-24 and YTD-24 due primarily to lower production volumes, including the impact of the closure of our Fraser Lake, B.C. lumber mill.

SYP shipment volumes increased from Q1-25 due primarily to higher production volumes and drawdown of finished goods inventory, discussed further in the section below. SYP shipment volumes decreased versus Q2-24 and YTD-24 due primarily to lower production volumes resulting from reduced operating schedules and mill closures.

The overall volume variance resulted in a nominal decrease in operating earnings and Adjusted EBITDA compared to Q1-25, a decrease of $2 million compared to Q2-24, and a decrease of $9 million compared to YTD-24.

We ship SPF to certain export markets, while our SYP sales are almost entirely within the U.S. The relative proportion of shipments of SPF by destination remained broadly comparable versus comparative periods.

Wood chip and other residuals sales increased from Q1-25 due primarily to higher production volumes, improved chip pricing, and the impact of the strengthening of the CAD against the USD on CAD-denominated sales of SPF wood chips. Wood chip and other residuals sales decreased from Q2-24 and YTD-24 due primarily to lower production volumes, lower chip pricing in the U.S. South, and the impact of the weakening of the CAD against the USD on SPF chip pricing.

Logs and other revenue decreased from Q1-25 due to lower volumes of logs sold during spring breakup. Logs and other revenue were broadly comparable versus Q2-24 and YTD-24.

Although SPF production volumes increased modestly from Q1-25, Q2-25 production continued to be impacted by log shortages at our B.C. lumber mills. SPF production volumes decreased versus Q2-24 and YTD-24 due to the impact of the closure of our Fraser Lake, B.C. lumber mill and incremental reductions in operating schedules due to log shortages.

In Q1-24, we announced and promptly completed the indefinite curtailment of operations at our Huttig, Arkansas lumber mill and the permanent closure of our Maxville, Florida lumber mill. Further, in Q3-24, we announced the indefinite curtailment of operations at our lumber mill in Lake Butler, Florida. Together, these actions reduced our SYP capacity by approximately 390 million board feet on an annual basis, representing 11% of our capacity at December 31, 2023. In addition, we selectively reduced operating hours and shifts across our SYP manufacturing facilities during 2024 and continue to do so in 2025.

SYP production volumes increased from Q1-25 due to higher operating schedules and the impact of weather-related impacts in the U.S. South in Q1-25. SYP production volumes decreased versus Q2-24 and YTD-24 due to the impacts of the aforementioned indefinite curtailments and closures, and reductions in operating schedules. Lower production from locations impacted by curtailments was partially offset by the ramp up of output from our more modern lower cost facilities.

Cost of products sold increased from Q1-25 due primarily to higher shipment volumes and a $26 million unfavourable impact relating to inventory valuation adjustment. Cost of products sold also increased from Q1-25 due to the impact of fixed costs incurred during this time of reduced logging activities. The unfavourable impact relating to inventory valuation adjustments resulted from having recorded a significant inventory valuation reserve in Q2-25 as product pricing decreased in particular close to the end of the quarter, while Q1-25 benefited from a modest release of inventory valuation reserves.

Cost of products sold decreased from Q2-24 and YTD-24 due primarily to lower shipment volumes, the impact of the weakening of the CAD against the USD on SPF costs, and lower SYP log costs. This was offset in part by higher unit manufacturing costs and higher SPF log costs.

Most of our SPF log requirements are harvested from crown lands owned by the provinces of B.C. or Alberta. B.C.’s stumpage system is tied to reported lumber prices, with a time lag, and publicly auctioned timber harvesting rights. Alberta’s stumpage system is correlated to published lumber prices with a shorter time lag.

Logging slowed significantly in Q2-25 due to seasonal wet and inaccessible land conditions, and accordingly the cost of SPF logs consumed was largely determined by the cost of the logs on hand at Q1-25. SPF log costs increased from Q2-24 due to higher logging and hauling costs and B.C. stumpage costs. SPF log costs increased from YTD-24 due to higher logging and hauling costs and higher estimated silviculture costs, offset in part by lower B.C. stumpage costs.

SPF unit manufacturing costs decreased from Q1-25 due to higher production in the period and lower labour and energy costs, offset in part by the strengthening of the CAD against the USD.

SPF unit manufacturing costs increased from Q2-24 and YTD-24 due primarily to lower production in the current year, higher labour costs, and higher repairs and maintenance costs. This was offset in part by the weakening of the CAD against the USD. Lower energy costs in the current year was a partial offsetting factor in the comparison to YTD-24 also.

SYP log costs decreased versus comparative periods as demand for logs moderated and we improved productivity in Q2-25.

SYP unit manufacturing costs were comparable versus Q1-25 as higher repairs and maintenance costs were offset by productivity improvements across most of our facilities.

SYP unit manufacturing costs increased from Q2-24 and YTD-24 due to the impact of lower production in the current year, higher labour costs, and higher repairs and maintenance costs. This was offset in part by the favourable cost impact of the indefinite curtailments and mill closures in the U.S. South.

Freight and other distribution costs generally trended with changes in shipment volumes with higher freight rates a contributing factor versus Q1-25.

The following table summarizes the impact of export duties, net, and tariffs on our Lumber segment:

Export duties expense decreased compared to Q1-25 due to lower product pricing and lower shipment volumes to the U.S. Export duties expense increased compared to Q2-24 and YTD-24 due to a higher cash deposit rate and higher product pricing, offset by lower shipment volumes to the U.S. in the current year.

The following table reconciles our cash deposits paid during the period to the amounts recorded in our earnings statement:

1.Represents combined CVD and ADD cash deposit rate of 11.89% for January 1, 2025 to June 27, 2025 and 9.25% for January 1,2024 to June 28, 2024.

2.No adjustments were recorded as the West Fraser Estimated ADD rate of 5.04% for Q2-25 and YTD-25 and 7.06% for Q2-24 and YTD-24 equaled the cash deposit rate.

Amortization expense was comparable versus Q1-25. Amortization expense decreased versus Q2-24 and YTD-24 due primarily to the impact of our lumber mill closures, offset in part by the completion of certain capital investments in our U.S. operations.

Selling, general and administration costs were comparable versus Q1-25. Selling, general and administration costs decreased versus Q2-24 and YTD-24 due primarily to the impact of indefinite curtailments and closures.

Operating earnings for the Lumber Segment decreased by $52 million compared to Q1-25, increased by $69 million compared to Q2-24, and increased by $141 million compared to YTD-24 for the reasons explained above.

Adjusted EBITDA for the Lumber Segment decreased by $52 million compared to Q1-25, increased by $66 million compared to Q2-24, and increased by $122 million compared to YTD-24. The following table shows the Adjusted EBITDA variance for the period.

The impact of changes relating to our sales of logs, wood chips, and other residuals is included under Other.

On November 25, 2016, a coalition of U.S. lumber producers petitioned the USDOC and the USITC to investigate alleged subsidies to Canadian softwood lumber producers and levy CVD and ADD duties against Canadian softwood lumber imports. The USDOC has chosen and continues to choose us as a “mandatory respondent” to both the countervailing and antidumping investigations, and as a result, we have received unique company-specific rates.

Developments in CVD and ADD rates

We began paying CVD and ADD duties in 2017 based on the determination of duties payable by the USDOC. The CVD and ADD cash deposit rates are updated based on the USDOC’s AR for each POI.

The respective Cash Deposit Rates, the AR POI Final Rate and the West Fraser Estimated ADD Rate for each period are as follows:

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.

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.

Accounting policy for duties

The CVD and ADD rates apply retroactively for each POI. We record CVD as export duty expense at the cash deposit rate until an AR finalizes a new applicable rate for each POI. We record ADD as export duty expense by estimating the rate to be applied for each POI by using our actual results and a similar calculation methodology as the USDOC and adjust when an AR finalizes a new applicable rate for each POI. The difference between the cash deposits paid and the export duty expense recognized for each POI is recorded on our balance sheet as export duty deposits receivable or payable.

The difference between the cash deposit amount and the amount that would have been due based on the final AR rate will incur interest based on the U.S. federally published interest rate. We record interest income on our duty deposits receivable, net of any interest expense on our duty deposits payable, based on this rate.

Appeals

Our 2024 annual MD&A includes additional details on Softwood Lumber Dispute appeals.

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

Our NA EWP segment includes our North American OSB, plywood, MDF, and LVL operations.

Sales increased versus Q1-25 due primarily to higher shipment volumes of all products, offset in part by lower OSB product pricing. Sales decreased versus Q2-24 and YTD-24 due primarily to lower OSB product pricing.

The price variance resulted in a decrease in operating earnings and Adjusted EBITDA of $48 million compared to Q1-25, a decrease of $223 million compared to Q2-24, and a decrease of $289 million compared to YTD-24.

OSB shipment volumes increased compared to Q1-25 due primarily to higher production levels, discussed further in the section below, and the impact of weather-related transportation delays in the U.S. South in Q1-25. OSB shipment volumes were broadly comparable to prior year periods.

Changes in plywood shipment volumes versus comparative periods were driven primarily by changes in production levels, discussed further in the section below.

The volume variance resulted in an increase in operating earnings and Adjusted EBITDA of $15 million compared to Q1-25, an increase of $5 million compared to Q2-24, and a decrease of $6 million compared to YTD-24.

The above table shows the proportion of shipments of OSB from our North American OSB operations to the U.S., Canada, and other export markets. For Q2-25 and comparative periods, substantially all plywood shipments were to Canada, while the majority of LVL shipments were to Canada. Approximately half of MDF shipments were to Canada in Q2-25, broadly consistent with comparative periods.

OSB production volumes increased from Q1-25 due to lower downtime at our facilities relating to capital projects and weather-related impacts, offset in part by incremental reductions in operating schedules to manage inventory levels. OSB production volumes decreased from Q2-24 due to incremental reductions in operating schedules to manage inventory levels, offset by the ramp-up of our Allendale, South Carolina mill. OSB production volumes decreased versus YTD-24 due to higher downtime at our facilities relating to capital projects and weather-related impacts in the U.S. South, and incremental reductions in operating schedules to manage inventory levels, offset in part by the ramp-up of our Allendale, South Carolina mill.

Plywood production volumes increased from Q1-25 due to lower maintenance downtime in the current period and improved productivity. Plywood production decreased versus Q2-24 and YTD-24 due to higher planned and unplanned downtime taken in the current year.

Cost of products sold increased versus Q1-25 due primarily to a $18 million unfavourable impact relating to inventory valuation adjustments, higher shipment volumes, the strengthening of the CAD against the USD, and higher fibre costs. This was offset in part by lower repairs and maintenance, resin and energy costs. We recorded significant inventory valuation reserves in Q2-25 as OSB product pricing declined.

Cost of products sold increased versus Q2-24 due primarily to a $17 million unfavourable impact relating to inventory valuation adjustments, higher OSB shipment volumes and higher labour, fibre, and energy costs, offset in part by lower resin costs and the weakening of the CAD against the USD.

Cost of products sold increased versus YTD-24 due primarily to a $18 million unfavourable impact relating to inventory valuation adjustments and higher labour and fibre costs, offset by lower shipment volumes, the weakening of the CAD against the USD, and lower resin costs.

Freight and other distribution costs increased from Q1-25 due to higher product shipment volumes and higher freight rates. Freight and other distribution costs increased from Q2-24 due to higher OSB shipment volumes and higher freight rates, offset by lower plywood shipment volumes. Freight and other distribution costs decreased from YTD-24 due to lower product shipment volumes, offset by higher freight rates.

Amortization expense and selling, general and administration costs were broadly comparable to comparative periods.

Operating earnings for the NA EWP Segment decreased by $57 million compared to Q1-25, decreased by $241 million compared to Q2-24, and decreased by $306 million from YTD-24 due to the reasons explained above.

Adjusted EBITDA for the NA EWP Segment decreased by $57 million compared to Q1-25, decreased by $240 million compared to Q2-24, and decreased by $303 million from YTD-24. The following table shows the Adjusted EBITDA variance for the period.

1.This is a non-GAAP financial measure. Refer to the “Non-GAAP and Other Specified Financial Measures” section of this document for more information on this measure.

Following our attaining sole control of CPP in Q1-24 and completion of the pulp mill disposals, the Pulp & Paper segment is comprised of our 100% interest in CPP and our 50%-owned joint operation, Alberta Newsprint Company. In light of the composition of the segment on a go-forward basis, the production and shipment volumes for all periods disclosed in the above table relate to those of NBSK pulp produced and shipped from CPP only and exclude BCTMP and UKP pulp amounts related to the disposed pulp mills.

The comparison versus comparative periods is impacted by the sale of Hinton pulp mill on February 3, 2024, the sale of Quesnel River Pulp mill and Slave Lake Pulp mill on April 20, 2024, and our attaining sole control of CPP in Q1-24.

Sales increased from Q1-25 due to higher NBSK shipment volumes. Sales were comparable to Q2-24 as the impact of the pulp mill disposals was offset by higher NBSK shipment volumes. Sales decreased from YTD-24 due to the impact of the pulp mill disposals, offset in part by higher NBSK product pricing and NBSK shipment volumes.

NBSK production volume increased from Q1-25 and Q2-24 due to improved productivity in the current period. NBSK production increased versus YTD-24 due to our attaining sole control of CPP in Q1-24 and less downtime taken in the current year.

Cost of products sold increased from Q1-25 due to higher NBSK shipment volumes, a $6 million unfavourable impact relating to inventory valuation adjustments, higher repairs and maintenance costs, higher fibre costs, and the strengthening of the CAD against the USD.

Cost of products sold increased versus Q2-24 due primarily to higher NBSK shipment volumes, offset by the impact of the pulp mill disposals. Cost of products sold decreased versus YTD-24 due primarily to the impact of the pulp mill disposals and the weakening of the CAD against the USD, offset in part by higher NBSK shipment volumes. The comparison of cost of products sold versus Q2-24 and YTD-24 were also both impacted by a $7 million unfavourable impact relating to inventory valuation adjustments.

Freight and other distribution costs increased compared to Q1-25 due to higher NBSK shipment volumes and higher freight rates. Freight and other distribution costs decreased versus Q2-24 and YTD-24 due to the impact of the pulp mill disposals, offset by higher NBSK shipment volumes.

Amortization expense was comparable versus Q1-25 and Q2-24. In 2024, the disposed pulp mills were classified as held for sale and were not amortized. Amortization expense increased from YTD-24 due to our attaining sole control of CPP in Q1-24.

Selling, general and administration costs were comparable versus all comparative periods.

We recorded an impairment loss of $5 million in Q2-24 and $3 million in YTD-24 upon completion of the pulp mill disposals.

Operating earnings for the Pulp & Paper Segment decreased by $8 million compared to Q1-25, decreased by $5 million compared to Q2-24, and decreased by $5 million from YTD-24 due to the reasons explained above.

Adjusted EBITDA for the Pulp & Paper Segment decreased by $8 million compared to Q1-25, decreased by $9 million compared to Q2-24, and decreased by $6 million from YTD-24 due to the reasons explained above.

1.This is a non-GAAP financial measure. Refer to the “Non-GAAP and Other Specified Financial Measures” section of this document for more information on this measure.

Our Europe EWP segment includes our U.K. and Belgium OSB, MDF, and particleboard operations. Revenues and expenses of our European operations, which have British pound sterling and Euro functional currencies, are translated at the average rate of exchange prevailing during the period.

Sales increased compared to Q1-25 due primarily to higher OSB product pricing, the strengthening of the GBP against the USD, and higher OSB shipment volumes. Sales increased compared to Q2-24 and YTD-24 due primarily to the strengthening of the GBP against the USD and higher shipment volumes. Higher OSB pricing was offset by lower MDF and particleboard product pricing.

The price variance resulted in an increase of $4 million in operating earnings and Adjusted EBITDA compared to Q1-25, a decrease of $1 million compared to Q2-24, and a decrease of $7 million from YTD-24. The price variance represents the impact of changes in product pricing in local currency terms, with any associated foreign exchange impact from the strengthening or weakening of the GBP against the USD presented under Other in the Adjusted EBITDA variance table.

The volume variance resulted in an increase in operating earnings and Adjusted EBITDA of $3 million compared to Q1-25, an increase of $3 million compared to Q2-24, and an increase of $6 million compared to YTD-24.

OSB production volumes increased compared to Q1-25 due to lower production curtailments taken to manage inventory levels in the current quarter. OSB production volumes were broadly comparable versus Q2-24 and YTD-24. MDF and particleboard production volumes increased versus all comparative periods due to lower production curtailments taken to manage inventory levels in the current year.

Cost of products sold increased versus all comparative periods, driven by higher OSB shipment volumes and the strengthening of the GBP against the USD. The increase versus prior year periods was also driven by higher fibre costs, with higher energy costs being a contributing factor in the comparison versus Q2-24.

Freight and other distribution costs increased versus all comparative periods due to higher shipment volumes.

Amortization expense in Q2-25 was broadly consistent with Q1-25. Amortization expense decreased versus prior year as certain assets reached the end of their estimated useful lives.

Selling, general and administration costs were broadly consistent with comparable periods.

Operating earnings for the Europe EWP Segment increased by $5 million compared to Q1-25, decreased by $2 million compared to Q2-24, and decreased by $1 million from YTD-24 due to the reasons explained above.

Adjusted EBITDA for the Europe EWP Segment increased by $5 million compared to Q1-25, decreased by $4 million compared to Q2-24, and decreased by $5 million from YTD-24.

Selling, general and administration costs for Q2-25 were $69 million (Q1-25 - $73 million; Q2-24 - $70 million). Selling, general and administration costs for YTD-25 were $142 million (YTD-24 - $146 million).

Selling, general and administration costs decreased versus Q1-25 due primarily to the impact of variable compensation expense recorded in Q1-25.

Selling, general and administration costs decreased versus Q2-24 due primarily to the impact of facility closures and curtailments and various organizational efficiency initiatives.

Selling, general and administration costs decreased versus YTD-24 due primarily to the impact of the pulp mill disposals and other facility curtailments and closures and the strengthening of the USD against the CAD. This was offset in part by the impact of variable compensation expense recorded in Q1-25 and our attaining sole control of CPP in Q1-24.

Selling, general and administration costs related to our operating segments are also discussed under “Discussion & Analysis of Quarterly Results by Product Segment”.

Our equity-based compensation includes our share purchase option, phantom share unit, and deferred share unit plans (collectively, the “Plans”). Our Plans are fair valued at each period-end, and the resulting expense or recovery is recorded in equity-based compensation expense over the vesting period.

Our valuation models consider various factors, with the most significant being the change in the market value of our shares from the beginning to the end of the relevant period. The expense or recovery does not necessarily represent the value that the holders of options and units will ultimately receive.

We recorded a $5 million recovery during Q2-25 (Q1-25 - recovery of $3 million; Q2-24 - recovery of $4 million) and a $8 million recovery during YTD-25 (YTD-24 - nominal expense). The recovery in Q2-25 and YTD-25 primarily reflects a decrease in the price of our common shares traded on the TSX.

Finance income, net includes interest earned on short-term investments and net interest income recognized on our Canadian lumber export duty deposits.

We recorded finance income, net of $4 million in Q2-25 (Q1-25 - finance income, net of $6 million; Q2-24 - finance income, net of $6 million) and finance income, net of $10 million in YTD-25 (YTD-24 - finance income, net of $15 million).

Finance income, net decreased from Q1-25 due primarily to the amendment of our existing $200 million term loan facility maturing July 2025 to a $300 million term loan facility maturing May 2028.

Finance income, net decreased compared to Q2-24 and YTD-24 due primarily to decreased interest income earned on lower cash and cash equivalents balances, offset in part by lower interest expense relating to long-term debt following the repayment of our senior notes in October 2024.

Other expense of $2 million was recorded in Q2-25 (Q1-25 - other expense of $3 million; Q2-24 - other income of $1 million). Other expense of $5 million was recorded in YTD-25 (YTD-24 - other expense of $5 million).

Other expense in Q2-25 relates primarily to foreign exchange losses recorded on our CAD-denominated monetary assets and liabilities as the USD weakened against the CAD, offset in part by gains on our electricity swaps, driven by increases in forward electricity prices over the remaining term of the contracts. Other expense in YTD-25 relates primarily to foreign exchange losses recorded on our CAD-denominated monetary assets and liabilities as the USD weakened against the CAD.

Q2-25 results include income tax recovery of $19 million, compared to income tax expense of $25 million in Q1-25 and income tax expense of $34 million in Q2-24, resulting in an effective tax rate of 44% in the current quarter compared to 37% in Q1-25 and 25% in Q2-24.

The effective tax rate in Q2-25 was primarily impacted by the impacts of functional currency differences and changes in valuation allowances. The effective tax rate can be sensitive to non-taxable permanent differences and differences in our jurisdictional tax rates in periods of lower pre-tax earnings.

YTD-25 income tax expense is $6 million compared to income tax expense of $50 million for YTD-24, resulting in effective tax rates of 25% and 26% respectively.

We recorded a translation gain of $34 million during Q2-25 (Q1-25 - translation gain of $16 million; Q2-24 - translation loss of $2 million) and a translation gain of $50 million during YTD-25 (YTD-24 - translation loss of $11 million).

In general, a strengthening (weakening) of the USD against the Canadian dollar, British pound sterling or Euro results in a translation loss (gain). The translation gains in the Q2-25 and YTD-25 reflect a weakening of the USD against the British pound sterling and Canadian dollar.

We recorded an after-tax actuarial gain of $7 million during Q2-25 (Q1-25 - after-tax actuarial loss of $3 million; Q2-24 - after-tax actuarial gain of $8 million) and an after-tax actuarial gain of $4 million during YTD-25 (YTD-24 - after-tax actuarial gain of $26 million).

The actuarial gains in Q2-25 and YTD-25 relate primarily to the impact of an increase in the weighted average discount rate used to calculate our plan liabilities, offset in part by lower returns on plan assets.

The seasonally adjusted annualized rate of U.S. housing starts was 1.32 million units in June 2025, with permits issued of 1.40 million units, according to the U.S. Census Bureau. While there are near-term uncertainties for new home construction, owing in large part to the level and rate of change of mortgage rates and the resulting impact on housing affordability, unemployment remains relatively low in the U.S. Further, the U.S. central bank has cut its key lending rate a total of 100 bps since September 2024 and Federal funds futures indicate prospects for additional rate cuts later in 2025, though there are evolving risks related to the U.S. administration’s tariff and other policies, which may be inflationary and could impact rates and rate cut expectations.

These developments notwithstanding, demand for new home construction and our wood building products may decline in the near term should the broader economy and employment slow or the trend in interest and mortgage rates negatively impact consumer sentiment and housing affordability.

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, and we are required to make deposits in respect of these duties. Whether and to what extent we can realize a selling price to recover the impact of duties payable will largely depend on the strength of demand for softwood lumber.

The USDOC commenced Administrative Review 7 (“AR7”) in February 2025, with final rates expected in 2026. Additional details can be found under the section “Discussion & Analysis of Quarterly Results by Product Segment - Lumber Segment - Softwood Lumber Dispute".

Anticipated shipment levels assume no significant change from current market demand conditions, typical seasonal demand patterns, sufficient availability of logs within our economic return criteria, and no further indefinite or permanent curtailments. Our operations and results could be negatively affected by increasing or elevated interest rates, duties and tariffs, softening demand, the availability of transportation, the availability of labour, disruption to the global economy resulting from the conflicts in Ukraine and the Middle East, inflationary pressures, including increases in energy prices, adverse weather conditions in our operating areas, intense competition for logs, elevated stumpage fees, and production disruptions due to other uncontrollable factors.

While the second quarter experienced some catch-up of previously delayed SYP lumber shipments caused by transportation and weather disruptions earlier in the year, the Lumber segment more broadly has experienced a slower than expected demand environment in the first half of 2025, owing primarily to continued housing affordability challenges as well as uncertainty related to impacts from the U.S. administration’s shifting tariff policies. Therefore, based on current conditions, including the mill closures and indefinite curtailments we announced last year and the uncertainties around the impact of tariffs, offset in part by the ongoing reliability and capital improvement gains across our lumber mill portfolio, we are reducing the ranges of our 2025 lumber shipments targets. For SPF shipments, we are now targeting 2.6 to 2.8 billion board feet (previously 2.7 to 2.9 billion board feet) and for SYP shipments, we are now targeting 2.4 to 2.6 billion board feet (previously 2.5 to 2.7 billion board feet). As the U.S. administration’s tariff and other policies evolve, we will evaluate the impact of the tariffs on our operations and consider whether any further revisions to our shipment estimates are warranted. On July 1, 2025, stumpage rates increased slightly in B.C. due to the market-based adjustments related to lumber prices, with inflationary pressures on development, logging and delivery costs continuing to provide upward bias to total fibre costs. Given the recent commodity price environment, B.C. stumpage rates are expected to track only modestly higher through Q3-25. In Alberta, Q3-25 stumpage rates are also expected to be slightly above Q2-25 levels as these rates are closely linked to the price of lumber but with a quicker response to changing lumber prices. Recent sawmill capacity curtailments across the U.S. South have created opportunities for lower log costs, with the pace of cost reductions largely stabilizing in Q2-25 but varying by region.

We expect average 2025 log costs across the U.S. South to be largely similar to those we experienced in the second half of 2024, though pulp mill curtailments and closures have caused a decline in the net prices received for sawmill residuals in some instances. Region-specific log costs and prices for residuals are likely to vary depending on the unique conditions in each procurement zone.

In our NA EWP segment, much like the Lumber segment, the second quarter experienced some catch-up of previously delayed shipments caused by transportation challenges earlier in the year. However, the latter part of the second quarter also saw a slowing of demand for our OSB products, which continued into the third quarter. Given this trend and the ongoing risks to our demand forecasts related to trade tariffs and policy uncertainty, we are reducing the range of our 2025 North American OSB target shipments. We are now targeting shipments of 6.3 to 6.5 billion square feet (3/8-inch basis) versus our previous target of 6.5 to 6.8 billion square feet (3/8-inch basis). As the U.S. administration’s tariff and other policies evolve, we will evaluate the impact of the tariffs on our operations and consider whether any further revisions to our shipment estimates are warranted. Start-up of the Allendale mill is ongoing and we continue to anticipate a ramp-up period for the mill of up to three years to meet targeted production levels. We expect our overall OSB platform to be better and lower cost with a modern Allendale facility optimized and running near full operating rates, and as with all our wood products operations, demand is a key input in determining our operating schedules across our manufacturing footprint. Input costs for the NA EWP business are still expected to be relatively stable through 2025. Pulp mill curtailments and closures in the U.S. South in recent years have caused some regional excess supply of pulpwood logs, the primary fibre source for OSB production.

In our Europe EWP segment, we continue to expect demand to improve for our MDF, particleboard and OSB panel products in 2025, recognizing there are ongoing macroeconomic uncertainties surrounding interest rates and economic growth in the region. As such, we reiterate guidance for 2025 OSB shipments in the range of 1.0 to 1.25 billion square feet (3/8-inch basis). Input costs for the Europe EWP business in 2025, including energy and resin costs, are still expected to stabilize near 2024 levels, though we note year-to-date energy costs have been significantly higher than levels experienced in the period before the 2022 escalation of the Ukraine and Russia conflict.

We will continue to regularly evaluate the factors above as well as evolving market conditions in making production decisions across the business.

We anticipate levels of operating cash flows and available liquidity will support our capital spending plans in 2025 as we look to operationalize the significant capital we have invested in recent years. Based on our current outlook, assuming no deterioration from current market demand conditions during the year and no additional lengthening of lead times for projects underway or planned, expected capital expenditures remain in the range of $400 million to $450 million in 20251. Our total capital budget consists of various improvement projects and maintenance expenditures, projects focused on optimization and automation of the manufacturing process, and projects targeted to reduce greenhouse gas emissions. Construction for the modernization of our Henderson, Texas lumber manufacturing facility is now largely complete and preparations are underway for the mill to begin its start-up curve. We anticipate 18 to 24 months to ramp-up the new Henderson mill and do not expect to realize meaningful incremental production from the mill until 2026.

We expect to maintain our investment grade issuer rating and intend to preserve sufficient liquidity to be able to take advantage of strategic growth opportunities that may arise.

Under our 2024 NCIB that expired February 28, 2025, we purchased 2,079,530 Common shares of the Company.

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. As of July 22, 2025, 741,748 Common shares have been repurchased for cancellation, leaving 3,126,429 available to purchase at our discretion until the expiry of the 2025 NCIB.

As of July 22, 2025, we have repurchased for cancellation 44,470,582 of the Company’s Common shares since the closing of the Norbord Acquisition on February 1, 2021 through the completion of the 2021 SIB, the 2022 SIB, and normal course issuer bids, equalling 82% of the shares issued in respect of the Norbord Acquisition.

We have paid a dividend in every quarter since we became a public company in 1986 and expect to continue this practice. At the latest declared quarterly dividend rate of $0.32 per share, the total anticipated cash payment of dividends in 2025 is $101 million based on the number of Common and Class B Common shares outstanding on June 27, 2025.

We will continue to consider share repurchases with excess cash, subject to regulatory approvals, if we are satisfied that this will enhance shareholder value and not compromise our financial flexibility.

Our business is cyclical and is subject to significant changes in cash flow over the business cycle. In addition, financial performance can be materially influenced by changes in product prices and the relative values of the Canadian and U.S. dollars. Our objective in managing capital is to ensure adequate liquidity and financial flexibility at all times, particularly at the lower points in the business cycle.

Our main policy relating to capital management is to maintain a strong balance sheet and otherwise meet financial tests that rating agencies commonly apply for investment-grade issuers of public debt. We are currently rated as an investment grade issuer by three major rating agencies.

We monitor and assess our financial performance to ensure that debt levels are prudent, taking into account the anticipated direction of the business cycle. When financing acquisitions, we combine cash on hand, debt, and equity financing in a proportion that is intended to maintain an investment-grade rating for debt throughout the cycle. Debt repayments are arranged, where possible, on a staggered basis that takes into account the uneven nature of anticipated cash flows. We have established committed revolving lines of credit that provide liquidity and flexibility when capital markets are restricted. In addition, as a normal part of our business, we have in the past and may from time to time seek to repurchase our outstanding securities through issuer bids or tender offers, open market purchases, privately negotiated transactions or otherwise. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual and legal restrictions and other factors.

A strong balance sheet and liquidity profile, along with our investment-grade issuer rating, are key elements of our goal to maintain a balanced capital allocation strategy. Priorities within this strategy include: reinvesting in our operations across all market cycles to strategically enhance productivity, product mix, and capacity; optimizing our portfolio of assets to reduce the variability of cash flows across market cycles; maintaining a leading cost position; maintaining financial flexibility to capitalize on growth opportunities, including the pursuit of acquisitions and larger-scale strategic growth initiatives; and returning capital to shareholders through dividends and share repurchases.

Our capital structure consists of Common share equity and long-term debt, and our liquidity includes our operating facilities.

1.Excludes demand line of credit dedicated to our jointly-owned newsprint operation as West Fraser cannot draw on it.

2.This is a capital management measure. Refer to the “Non-GAAP and Other Specified Financial Measures” section of this document for more information on this measure.

Available liquidity as at June 27, 2025 was $1,692 million (December 31, 2024 - $1,685 million). Available liquidity includes cash and cash equivalents, cheques issued in excess of funds on deposit, and amounts available on our operating loans, excluding the demand line of credit dedicated to our 50% jointly-owned newsprint operation.

Please refer to the “Cash Flow” section for analysis of the changes in cash and cash equivalents. Net debt to total capital and total debt to total capital were comparable to Q4-24 and we remain well positioned with a strong balance sheet and liquidity profile.

As at June 27, 2025, our credit facilities consisted of a $1 billion committed revolving credit facility which matures May 2030, $25 million of uncommitted revolving credit facilities available to our U.S. subsidiaries, a $20 million (£15 million) credit facility dedicated to our European operations, and a $11 million (CAD$15 million) demand line of credit dedicated to our jointly‑owned newsprint operation.

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 renewed credit facility was made available on substantially the same terms and conditions as our existing credit facility.

In May 2025, in addition to the renewal of our $1 billion revolving credit facility, we also increased and extended our existing $200 million term loan facility maturing July 2025. The modified term loan facility is for $300 million and matures May 2028. Interest on the term loan facility is payable at floating rates based on US Base Rate Advances or SOFR Advances at our option. This loan is repayable at any time, in whole or in part, at our option and without penalty but cannot be redrawn after payment.

We have interest rate swap contracts to pay fixed interest rates and receive variable interest rates on $200 million notional principal amount of indebtedness expiring July 25, 2025. Prior to expiry, these swap agreements have the effect of fixing the interest rate on $200 million of the term loan facility discussed above, with the remaining $100 million being subject to a floating rate.

We are considered investment grade by three leading rating agencies. On October 22, 2024, Moody's upgraded our issuer rating to Baa2, with an outlook of stable. The ratings in the table below are as at July 22, 2025.

These ratings are not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time by the rating agencies.

Our outstanding Common share equity consists of 76,576,171 Common shares and 2,281,478 Class B Common shares for a total of 78,857,649 Common shares issued and outstanding as at July 22, 2025. As of July 22, 2025, we held 13,390 Common shares as treasury shares for cancellation.

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. As of July 22, 2025, we have repurchased 741,748 common shares under our 2025 NCIB program.

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. Under this program, we repurchased 2,079,530 common shares for cancellation.

The following table shows our purchases under our NCIB programs in 2024 and 2025:

As at July 22, 2025, there were 719,092 share options outstanding with exercise prices ranging from CAD$40.97 to CAD$123.63 per Common share.

Our cash is deployed primarily for operating purposes, interest payments, repayment of debt, investments in property, plant and equipment, acquisitions, share repurchases, and dividends. In normal business cycles and in years without a major acquisition or debt repayment, cash on hand and cash provided by operations have typically been sufficient to meet these uses.

We are exposed to commodity price changes. To manage our liquidity risk, we maintain adequate cash and cash equivalents balances and appropriate lines of credit. In addition, we regularly monitor and review both actual and forecasted cash flows.

Refinancing risks are managed by extending maturities through regular renewals and refinancing when market conditions are supportive.

The table above shows the main components of cash flows provided by or used for operating activities for each period.

Cash provided by operating activities decreased versus comparative periods due primarily to lower earnings driven by lower OSB pricing, offset in part by higher lumber pricing, changes in income tax payments, and incremental releases in working capital.

Income tax payments for YTD-25 included top-up payments for the prior year and were net of $34 million of refunds on account of a settlement agreement reached with the CRA in Q1-25 with the funds received in Q2-25.

Working capital decreased in Q2-25 due primarily to lower inventories and receivables, offset in part by higher prepaids and lower payables and accrued liabilities.

Decreases in inventories related primarily to consumption of log inventory. 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 spring and summer months, when logging is curtailed due to wet and inaccessible land conditions. Q2-25 also saw a decrease in volumes of NA EWP and SYP lumber finished goods inventory.

Decreases in receivables in Q2-25 driven primarily by lower OSB and lumber product pricing. Prepaids increased due primarily to the timing of certain insurance renewals and property tax payments made. Payables and accrued liabilities decreased in Q2-25 due primarily to lower stumpage and contractor accruals as logging was curtailed during the second quarter.

Working capital increased in YTD-25 due to higher receivables and prepaids, offset in part by higher payables and accrued liabilities.

Receivables increased in YTD-25 due primarily to higher shipment activity at the end of Q2-25. Prepaids increased due primarily to the reasons discussed above. Payables and accrued liabilities increased in YTD-25 due primarily to lower accrued equity-based compensation and timing of payments.

Cash used in financing activities increased versus comparative periods due primarily to proceeds from amendment of our term loan facility. We received $100 million as we increased and extended our existing $200 million term loan facility maturing July 2025. The modified term loan facility is for $300 million and matures May 2028.

We returned $34 million and $80 million respectively during the three and six months ended June 27, 2025 to our shareholders through Common shares repurchased under our NCIB, compared to $71 million and $79 million respectively during the three and six months ended June 28, 2024.

We returned a total of $25 million and $51 million during the three and six months ended June 27, 2025 to our shareholders through dividend payments, which was comparable to the same periods in 2024.

Capital expenditures of $78 million in Q2-25 (Q2-24 - $102 million) and $182 million in YTD-25 (YTD-24 - $224 million) reflect our strategy of continued reinvestment in our mills.

We received $124 million of proceeds during the six months ended June 28, 2024 in relation to the sale of Hinton pulp mill on February 3, 2024 and the sale of Quesnel River Pulp mill and Slave Lake Pulp mill on April 20, 2024.

Our business is subject to a number of risks and uncertainties. Risks and uncertainties are included in our Annual MD&A, as updated in the disclosures in our quarterly MD&A, our public filings with securities regulatory authorities, and also include additional risks and uncertainties identified in this MD&A.

West Fraser is responsible for establishing and maintaining disclosure controls and procedures and internal control over financial reporting, each as defined in NI 52-109 in Canada and under the Securities Exchange Act of 1934, as amended, in the United States.

We have designed our disclosure controls and procedures to provide reasonable assurance that information that is required to be disclosed by us in our annual filings, interim filings and other reports that we file or submit under securities legislation is recorded, processed, summarized, and reported within the time periods specified in the securities legislation. These include controls and procedures designed to ensure that information that we are required to disclose under securities legislation is accumulated and communicated to our management, including our President and Chief Executive Officer (“CEO”) and the Senior Vice-President, Finance and Chief Financial Officer (“CFO”), as appropriate to allow timely decisions regarding required disclosure.

Management, under the supervision of the CEO and CFO, is responsible for establishing and maintaining adequate internal control over financial reporting, as defined under NI 52-109 in Canada and the Securities Exchange Act of 1934, as amended, in the United States, 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.

There has been no change in our internal control over financial reporting during the three months ended June 27, 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Due to its inherent limitations, internal control over financial reporting may not prevent or detect misstatements on a timely basis. Additionally, projections of any evaluation of the effectiveness of internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Throughout this MD&A, we make reference to (i) certain non-GAAP financial measures, including Adjusted EBITDA and Adjusted EBITDA by segment (our “Non-GAAP Financial Measures”), (ii) certain capital management measures, including available liquidity, total debt to capital ratio, and net debt to capital ratio (our “Capital Management Measures”), and (iii) certain supplementary financial measures, including our expected capital expenditures (our “Supplementary Financial Measures”). We believe that these Non-GAAP Financial Measures, Capital Management Measures, and Supplementary Financial Measures (collectively, our “Non-GAAP and other specified financial measures”) are useful performance indicators for investors to understand our operating and financial performance and our financial condition. These Non-GAAP and other specified financial measures are not generally accepted financial measures under IFRS Accounting Standards and do not have standardized meanings prescribed by IFRS Accounting Standards. Investors are cautioned that none of our Non-GAAP Financial Measures should be considered as an alternative to earnings or cash flow, as determined in accordance with IFRS Accounting Standards. As there is no standardized method of calculating any of these Non-GAAP and other specified financial measures, our method of calculating each of them may differ from the methods used by other entities and, accordingly, our use of any of these Non-GAAP and other specified financial measures may not be directly comparable to similarly titled measures used by other entities. Accordingly, these Non-GAAP and other specified financial measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS Accounting Standards.

The reconciliation of the Non-GAAP measures used and presented by the Company to the most directly comparable measures under IFRS Accounting Standards is provided in the tables set forth below.

Adjusted EBITDA is used to evaluate the operating and financial performance of our operating segments, generate future operating plans, and make strategic decisions. Adjusted EBITDA is defined as earnings determined in accordance with IFRS Accounting Standards adding back the following line items from the consolidated statements of earnings and comprehensive earnings: finance income or expense, tax provision or recovery, amortization, equity-based compensation, restructuring and impairment charges, and other income or expense.

Adjusted EBITDA by segment is defined as operating earnings determined for each reportable segment in accordance with IFRS Accounting Standards adding back the following line items from the consolidated statements of earnings and comprehensive earnings for that reportable segment: amortization, equity-based compensation, and restructuring and impairment charges.

EBITDA is commonly reported and widely used by investors and lending institutions as an indicator of a company’s operating performance, ability to incur and service debt, and as a valuation metric. We calculate Adjusted EBITDA and Adjusted EBITDA by segment to exclude items that do not reflect our ongoing operations and should not, in our opinion, be considered in a long-term valuation metric or should not be included in an assessment of our ability to service or incur debt.

The following table reconciles Adjusted EBITDA to the most directly comparable IFRS measure, earnings.
