NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(In thousands of U.S. dollars, except share and per share data)

Note 1. The Company and Summary of Significant Accounting Policies

Nature of Operations and Basis of Presentation

The Interim Consolidated Financial Statements contained herein include the accounts of Mercer International Inc. (“Mercer Inc.”) and all of its subsidiaries (collectively the “Company”). Mercer Inc. owns 100% of its subsidiaries. The Company’s shares of common stock are quoted and listed for trading on the NASDAQ Global Select Market.

The Interim Consolidated Financial Statements have been prepared by the Company pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). The consolidated balance sheet information as of December 31, 2024 was derived from the Company’s audited Consolidated Financial Statements, but does not contain all of the footnote disclosures from the annual Consolidated Financial Statements. The footnote disclosure included herein has been prepared in accordance with accounting principles generally accepted for interim financial statements in the United States (“GAAP”). The unaudited Interim Consolidated Financial Statements should be read together with the audited Consolidated Financial Statements and accompanying notes included in the Company’s latest Annual Report on Form 10‑K for the fiscal year ended December 31, 2024. In the opinion of the Company, the unaudited Interim Consolidated Financial Statements contained herein have been prepared on a consistent basis with the audited Consolidated Financial Statements and accompanying notes included in the Company’s latest Annual Report on Form 10‑K for the fiscal year ended December 31, 2024 and contain all adjustments necessary for a fair statement of the results of the interim periods included. The results for the periods included herein may not be indicative of the results for the entire year.

In these Interim Consolidated Financial Statements, unless otherwise indicated, all amounts are expressed in United States dollars (“U.S. dollars” or “$”). The symbol “€” refers to euros and the symbol “C$” refers to Canadian dollars.

Use of Estimates

Preparation of financial statements and related disclosures in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant management judgment is required in determining the accounting for, among other things, future cash flows associated with impairment testing for goodwill and long-lived assets, depreciation and amortization, pension and other post-retirement benefit obligations, deferred income taxes (valuation allowance and permanent reinvestment), the allocation of the purchase price in a business combination to the assets acquired and liabilities assumed, revenues under long-term contracts, inventory impairment, assets and liabilities classified as held for sale and the fair value of disposal groups, legal liabilities and contingencies. Actual results could differ materially from these estimates and changes in these estimates are recorded when known.

New Accounting Pronouncements

Improvements to Income Tax Disclosures

In December 2023, the FASB issued ASU 2023-09, which requires additional disaggregation of the reconciliation between the statutory and effective tax rate for an entity and of income taxes paid. The amendments improve the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. The Company continues to assess the impact of ASU 2023-09.

(In thousands of U.S. dollars, except share and per share data)

Disaggregation of Income Statement Expenses

In November 2024, the FASB issued ASU 2024-03, which expands disclosures about specific expense categories presented on the face of the income statement and addresses requests from investors for more detailed information about the types of expenses (including purchases of inventory, employee compensation, depreciation and amortization) in commonly presented expense captions (such as cost of sales and selling, general and administrative expenses). ASU 2024-03 is effective for fiscal years beginning after December 15, 2026 and interim periods thereafter with early adoption permitted. The Company is currently assessing the impact of ASU 2024-03.

Note 2. Assets and Liabilities Classified as Held for Sale

The Company continues to actively market the sandalwood business and expects a sale to occur within the next 12 months. Accordingly, the assets and associated liabilities of the business, referred to as the “disposal group”, continue to be classified as held for sale.

The Company participates in a multiemployer plan for the hourly-paid employees at the Celgar mill. The contributions to the plan are determined based on a percentage of pensionable earnings pursuant to a collective bargaining agreement. The Company has no current or future contribution obligations in excess of the contractual contributions. During the three and six months ended June 30, 2025, the Company made contributions of $683 and $1,389, respectively, to this plan (2024 – $613 and $1,134).

For the three and six months ended June 30, 2025, services from the Company’s 26% owned wood purchasing operation were $3,434 and $5,662, respectively, (2024 – $1,367 and $2,315) and as of June 30, 2025, the Company had a payable balance to the operation of $100 (December 31, 2024 – receivable of $50).

Note 12. Segment Information

The Company is managed based on the primary products it manufactures: pulp and solid wood. The Company’s four pulp mills are aggregated into the pulp segment. The Friesau sawmill, the Torgau facility and the mass timber facilities are aggregated into the solid wood segment. The operating results for the pulp and solid wood segments are regularly reviewed by the Company’s chief operating decision maker (the “CODM”) to assess segment performance and to make decisions about resource allocation. The Company’s CODM is the Chief Executive Officer.

Revenues between segments are accounted for at prices that approximate fair value. These include revenues from the sale of residual fiber from the solid wood segment to the pulp segment for use in the pulp production process and from the sale of residual fuel from the pulp segment to the solid wood segment for use in energy production.

Change in segment measure of profit or loss

In 2024, the Company changed its segment measure from operating income (loss) to net income (loss) before interest, tax, depreciation and amortization and impairments of long-lived assets (“Segment Operating EBITDA”). The CODM uses Segment Operating EBITDA as the primary measure in assessing the operating performance of each reportable segment through periodic reviews and comparison of segment operating trends and identifying strategies to improve the allocation of resources amongst the reportable segments. Segment Operating EBITDA is different from operating income (loss) as it excludes depreciation and amortization and impairment of long-lived assets, as those items are not considered indicative of ongoing core operations. Comparative periods have been recast to conform with the current period’s presentation.

Total assets and the income or loss items following Segment Operating EBITDA, other than depreciation, amortization and impairment of long-lived assets, are not allocated to the segments, as those items are reviewed separately by management.

Note 13. Financial Instruments and Fair Value Measurement

Due to their short-term maturity, the carrying amounts of cash and cash equivalents, accounts receivable, and accounts payable and other approximates their fair value. The estimated fair values of the Company’s outstanding debt under the fair value hierarchy as of June 30, 2025 and December 31, 2024 were as follows:

Fair value measurements as of
June 30, 2025 using:
Description Level 1 Level 2 Level 3 Total
Revolving credit facilities $ $ 217,201 $ $ 217,201
Senior notes 1,119,442 1,119,442
$ $ 1,336,643 $ $ 1,336,643
Fair value measurements as of
--- --- --- --- --- --- --- --- --- ---
December 31, 2024 using:
Description Level 1 Level 2 Level 3 Total
Revolving credit facilities $ $ 169,169 $ $ 169,169
Senior notes 1,186,921 1,186,921
$ $ 1,356,090 $ $ 1,356,090

The carrying value of the revolving credit facilities classified as Level 2 approximates the fair value as the variable interest rates reflect current interest rates for financial instruments with similar characteristics and maturities.

The fair value of the senior notes classified as Level 2 was determined using quoted prices in a dealer market, or using recent market transactions. The Company’s senior notes are not carried at fair value in the Interim Consolidated Balance Sheets as of June 30, 2025 or December 31, 2024. However, fair value disclosure is required. The carrying value of the Company’s senior notes, net of unamortized note issuance costs, was $1,267,135 as of June 30, 2025 (December 31, 2024 – $1,266,018).

Credit Risk

The Company’s exposure to credit losses may increase if its customers' production and other costs are adversely affected by inflation, interest rate levels and tariffs. Although the Company has historically not experienced significant credit losses, it is possible that there could be a material adverse impact from potential adjustments of the carrying amount of trade receivables if the cash flows of the Company’s customers are adversely impacted by inflation, interest rate levels and tariffs. As of June 30, 2025, the Company has not had significant credit losses.

As of June 30, 2025, the carrying amount of cash and cash equivalents of $146,499 and accounts receivable of $335,394 recorded in the Interim Consolidated Balance Sheet, net of any allowances for losses, represent the Company’s maximum exposure to credit risk.

Note 14. Commitments and Contingencies

  • The Company is involved in legal actions and claims arising in the ordinary course of business. While the outcome of any legal actions and claims cannot be predicted with certainty, it is the opinion of management that the outcome of any such claims which are pending or threatened, either individually or on a combined basis, will not have a material adverse effect on the consolidated financial condition, results of operations or liquidity of the Company.
  • The Company is subject to regulations that require the handling and disposal of asbestos in a prescribed manner if a property undergoes a major renovation or demolition. Otherwise, the Company is not required to remove asbestos from its facilities. Generally asbestos is found on steam and condensate piping systems as well as certain cladding on buildings and in building insulation throughout older facilities. The Company’s obligation for the proper removal and disposal of asbestos products from the Company’s mills is a conditional asset retirement obligation. As a result of the longevity of the Company’s mills, due in part to the maintenance procedures and the fact that the Company does not have plans for major changes that require the removal of asbestos, the timing of the asbestos removal is indeterminate. As a result, the Company is currently unable to reasonably estimate the fair value of its asbestos removal and disposal obligation. The Company will recognize a liability in the period in which sufficient information is available to reasonably estimate its fair value.

NON-GAAP FINANCIAL MEASURES

This quarterly report on Form 10-Q contains “non-GAAP financial measures”, that is, financial measures that either exclude or include amounts that are not excluded or included in the most directly comparable measure calculated and presented in accordance with the generally accepted accounting principles in the United States, referred to as “GAAP”. Specifically, we make use of the non-GAAP financial measure “Operating EBITDA”.

We define Operating EBITDA as operating loss plus depreciation and amortization and long-lived asset impairment charges. We use Operating EBITDA as a benchmark measurement of our own operating results and as a benchmark relative to our competitors. We consider it to be a meaningful supplement to operating loss as a performance measure primarily because depreciation expense and long-lived asset impairment charges are not actual cash costs, and depreciation expense varies widely from company to company in a manner that we consider largely independent of the underlying cost efficiency of our operating facilities. In addition, we believe Operating EBITDA is commonly used by securities analysts, investors and other interested parties to evaluate our financial performance.

Operating EBITDA does not reflect the impact of a number of items that affect our net loss, including financing costs, income taxes and the effect of derivative instruments. Operating EBITDA is not a measure of financial performance under GAAP, and should not be considered as an alternative to net loss or operating loss as a measure of performance, or as an alternative to net cash from (used in) operating activities as a measure of liquidity. Operating EBITDA is an internal measure and therefore may not be comparable to other companies.

Operating EBITDA has significant limitations as an analytical tool, and should not be considered in isolation, or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are that Operating EBITDA does not reflect: (i) our cash expenditures, or future requirements, for capital expenditures or contractual commitments; (ii) changes in, or cash requirements for, working capital needs; (iii) the significant interest expense, or the cash requirements necessary to service interest or principal payments, on our outstanding debt; (iv) the impact of realized or marked to market changes in our derivative positions, which can be substantial; and (v) the impact of impairment charges against our investments or assets. Because of these limitations, Operating EBITDA should only be considered as a supplemental performance measure and should not be considered as a measure of liquidity or cash available to us to invest in the growth of our business. Because all companies do not calculate Operating EBITDA in the same manner, Operating EBITDA as calculated by us may differ from Operating EBITDA or EBITDA as calculated by other companies. We compensate for these limitations by using Operating EBITDA as a supplemental measure of our performance and by relying primarily on our GAAP financial statements.

Operating EBITDA is a non-GAAP financial measure at the consolidated level and is considered different from Operating EBITDA at the segment level, referred to as “Segment Operating EBITDA”, which is our single measure of segment profit or loss presented in our financial statements under GAAP. For more information on Segment Operating EBITDA, refer to the segment information note within our consolidated financial statements.

The following discussion and analysis of our results of operations and financial condition for the three and six months ended June 30, 2025 should be read in conjunction with our Interim Consolidated Financial Statements and related notes included in this quarterly report, as well as our most recent annual report on Form 10-K for the fiscal year ended December 31, 2024 filed with the Securities and Exchange Commission, referred to as the “SEC”.

Results of Operations

General

We have two reportable operating segments:

  • Pulp – consists of the manufacture, sale and distribution of pulp, electricity and chemicals at our pulp mills.
  • Solid Wood – consists of the manufacture, sale and distribution of lumber, manufactured products (including CLT, glulam and finger joint lumber), wood pallets, electricity, biofuels and wood residuals at our sawmills and other facilities in Germany and our mass timber facilities in North America.

Each segment offers primarily different products and requires different manufacturing processes, technology and sales and marketing.

Current Market Environment

In the second quarter of 2025, our NBSK pulp sales realizations remained strong in both North America and Europe compared to the first quarter of 2025 driven by steady demand and supply constraints. In China, both our NBSK and NBHK pulp sales realizations decreased in the second quarter of 2025 compared to the first quarter of 2025 as a result of weak demand driven by global trade policy uncertainty. In North America, NBHK pulp sales realizations modestly increased in the second quarter of 2025 compared to the first quarter of 2025 due to stable demand.

In the second quarter of 2025, our lumber sales realizations increased in both the U.S. and Europe compared to the first quarter of 2025 due to stable demand and reduced supply.

As of June 30, 2025, the third-party industry quoted NBSK pulp list prices in Europe and North America were approximately $1,510 per ADMT and $1,790 per ADMT, respectively, and the third-party industry quoted NBSK pulp net price in China was approximately $690 per ADMT. Prices for China are net of discounts, allowances and rebates.

FORM 10-Q

QUARTERLY REPORT - PAGE 26

We currently expect NBSK pulp prices to decrease in all our key markets in the third quarter of 2025 driven by slower demand as a result of seasonality and a weakened economic environment caused by global trade policy uncertainty. For NBHK pulp prices, we currently expect relatively steady prices in the third quarter of 2025.

In the third quarter of 2025, we currently expect lumber prices to modestly increase in Europe primarily driven by strong demand and higher fiber costs. In the U.S., we currently expect higher prices in the third quarter of 2025 as a result of lower supply and the impact from duties imposed on Canadian producers. In the third quarter of 2025, we currently expect pallet prices to remain flat due to continued weak economic conditions in Europe and mass timber prices to remain relatively steady.

Per unit fiber costs for the pulp segment increased in the second quarter of 2025 compared to the first quarter of 2025 primarily as a result of strong demand and steady supply. For the third quarter of 2025, we currently expect per unit fiber costs to be lower for our German pulp mills due to reduced demand and relatively stable for our Canadian pulp mills.

Per unit fiber costs for the solid wood segment increased in the second quarter of 2025 compared to the first quarter of 2025 as a result of strong demand in Germany. For the third quarter of 2025, we currently expect modestly higher per unit fiber costs for our solid wood segment due to a temporary reduction in regional logging in Germany and continued strong demand.

Demand and pricing for our products may be further impacted by ongoing developments in international trade policies, including tariffs proposed or imposed by the United States on goods originating from Canada, the European Union and other countries, and related countermeasures. As these developments are ongoing and subject to change, it is difficult to predict such impact at this time. However, in the second quarter of 2025, uncertainties surrounding these developments have impacted demand for pulp in China. See Item 1A. Risk Factors in our annual report on Form 10-K for the fiscal year ended December 31, 2024 for further information.

Consolidated – Three Months Ended June 30, 2025 Compared to Three Months Ended June 30, 2024

Total revenues for the second quarter of 2025 decreased by approximately 9% to $453.5 million from $499.4 million in the same quarter of 2024 primarily due to lower sales realizations and volumes from our pulp and manufactured products partially offset by higher lumber sales realizations.

Costs and expenses in the second quarter of 2025 decreased by approximately 6% to $511.9 million from $543.2 million in the same quarter of 2024 driven by fewer days of planned annual maintenance downtime in the second quarter of 2025 at our pulp mills. This decrease was partially offset by foreign exchange losses, higher per unit fiber costs and an $11.0 million non-cash impairment recognized against hardwood inventory at our Peace River mill. The foreign exchange losses resulted from the impact of a weaker dollar on the revaluation of dollar denominated accounts receivables held at our operations, and on our euro denominated costs and expenses compared to the same quarter of 2024. In the second quarter of 2024, costs and expenses included a non-cash goodwill impairment of $34.3 million related to the Torgau facility, which was recognized as a result of ongoing weakness in lumber, pallet and biofuels markets in Europe stemming from high interest rates and other economic conditions.

In the second quarter of 2025, cost of sales depreciation and amortization was relatively flat at $37.5 million compared to $39.9 million in the same quarter of 2024.

Selling, general and administrative expenses were relatively steady at $30.4 million in the second quarter of 2025 compared to $29.8 million in the same quarter of 2024.

In the second quarter of 2025, we had a negative foreign exchange impact of approximately $21.1 million on operating loss compared to the same quarter of 2024. This negative impact was primarily due to foreign exchange losses on the revaluation of dollar denominated accounts receivables held at our operations, as the dollar weakened relative to the euro and Canadian dollar at the end of the second quarter of 2025, and the negative effect of a weaker dollar on our euro denominated costs and expenses compared to the same quarter of 2024.

In the second quarter of 2025, our operating loss was $58.4 million compared to $43.8 million in the same quarter of 2024 primarily due to lower pulp and manufactured products sales realizations, negative foreign exchange impacts from a weaker dollar, higher per unit fiber costs and the non-cash impairment recognized against hardwood inventory. These adverse impacts were partially offset by fewer days of planned annual maintenance downtime in the second quarter of 2025 at our pulp mills and higher lumber sales realizations. In the second quarter of 2024, our operating loss included a non-cash goodwill impairment of $34.3 million related to the Torgau facility.

Interest expense was relatively flat at $28.4 million in the second quarter of 2025 compared to $26.8 million in the same quarter of 2024.

In the second quarter of 2025, other expenses were $1.1 million compared to other income of $4.3 million in the same quarter of 2024. Other expenses in the second quarter of 2025 primarily consisted of foreign exchange losses on the revaluation of dollar denominated cash held at our operations as the dollar weakened against the euro at the end of the second quarter of 2025 mostly offset by interest earned on cash. In the second quarter of 2024, other income primarily consisted of interest earned on cash and foreign exchange gains on the revaluation of dollar denominated cash held at our operations as the dollar strengthened at the end of the second quarter of 2024.

In the second quarter of 2025, we had an income tax recovery of $1.9 million, or an effective tax rate of 2%. In the same quarter of 2024, we had an income tax provision of $1.3 million on a loss before income taxes. Our effective tax rates were different from the statutory rates of the jurisdictions in which we operate as we do not recognize tax recoveries for certain entities which we do not expect to realize a tax benefit. In the second quarter of 2024, the effective tax rate was also impacted by the non-deductibility of the non-cash goodwill impairment.

In the second quarter of 2025, our net loss was $86.1 million, or $1.29 per share, compared to $67.6 million, or $1.01 per share, in the same quarter of 2024. The net loss in the second quarter of 2024 included the non-cash goodwill impairment of $34.3 million, or $0.51 per share.

In the second quarter of 2025, Operating EBITDA decreased to negative $20.9 million from positive $30.4 million in the same quarter of 2024 primarily as a result of lower pulp and manufactured products sales realizations, negative

foreign exchange impacts from a weaker dollar, higher per unit fiber costs and the non-cash impairment recognized on hardwood inventory. These decreases were partially offset by fewer days of planned annual maintenance downtime at our pulp mills and higher lumber sales realizations.

Total pulp production in the second quarter of 2025 increased by approximately 8% to 457,117 ADMTs compared with 421,692 ADMTs in the same quarter of 2024 primarily as a result of fewer days of planned annual maintenance downtime in the second quarter of 2025. In the second quarter of 2025, our pulp mills had 29 days of downtime (approximately 40,900 ADMTs) which included 23 days of planned annual maintenance and six additional days due to slower than expected start-up. In the same quarter of 2024, our pulp mills had 44 days of downtime (approximately 77,600 ADMTs) which included 37 days of planned annual maintenance and seven additional days due to slower than expected start-up.

We estimate that planned annual maintenance downtime in the second quarter of 2025 adversely impacted our Segment Operating EBITDA by approximately $26.4 million, comprised of approximately $19.4 million in direct out-of-pocket expenses and the balance in reduced production. Many of our competitors that report their financial results using International Financial Reporting Standards, referred to as “IFRS”, capitalize their direct costs of maintenance downtime.

In the third quarter of 2025, we currently expect a total of 18 days of planned annual maintenance downtime (approximately 19,600 ADMTs) at our pulp mills.

Total pulp sales volumes in the second quarter of 2025 were relatively flat at 426,731 ADMTs compared to 433,320 ADMTs in the same quarter of 2024.

In the second quarter of 2025, the third-party industry quoted average list price for NBSK pulp in Europe was relatively flat compared to the same quarter of 2024. In the second quarter of 2025, the third-party industry quoted average list price for NBSK pulp in North America increased from the same quarter of 2024 due to stronger demand and supply constraints. In the second quarter of 2025, the third-party industry quoted average net price for NBSK pulp in China decreased from the same quarter of 2024 as a result of weaker demand driven by the current economic climate and global trade policy uncertainty. Third-party industry quoted average list prices for NBSK pulp in Europe and North America were approximately $1,553 per ADMT and $1,820 per ADMT, respectively, in the second quarter of 2025 compared to approximately $1,602 per ADMT and $1,697 per ADMT, respectively, in the same quarter of 2024. Third-party industry quoted average net prices for NBSK pulp in China were approximately $734 per ADMT in the second quarter of 2025 compared to approximately $811 per ADMT in the same quarter of 2024.

In the second quarter of 2025, the third-party industry quoted average list price for NBHK pulp in North America decreased from the same quarter of 2024 due to weaker demand. In the second quarter of 2025, the third-party industry quoted average net price for NBHK pulp in China decreased from the same quarter of 2024 driven by weak demand due to the current economic climate and global trade policy uncertainty. Third-party industry quoted average list prices for NBHK pulp in North America were approximately $1,310 per ADMT in the second quarter of 2025 compared to approximately $1,437 per ADMT in the same quarter of 2024. Third-party industry quoted average net prices for NBHK pulp in China were approximately $533 per ADMT in the second quarter of 2025 compared to approximately $735 per ADMT in the same quarter of 2024.

Our average NBSK pulp sales realizations in the second quarter of 2025 decreased by approximately 7% to $758 per ADMT from $811 per ADMT in the same quarter of 2024 primarily due to lower net prices in China partially offset by higher prices in North America. In the second quarter of 2025, average NBHK pulp sales realizations decreased by approximately 18% to $575 per ADMT from $701 per ADMT in the same quarter of 2024 as a result of lower prices in China and North America.

In the second quarter of 2025, we had a negative foreign exchange impact of approximately $17.7 million on Segment Operating EBITDA compared to the same quarter of 2024. This negative impact was primarily due to foreign exchange losses on the revaluation of dollar denominated accounts receivables held at our operations, as the dollar weakened relative to the euro and Canadian dollar at the end of June 2025, and the negative impact of a weaker dollar on our euro denominated costs and expenses compared to the same quarter of 2024.

In the second quarter of 2025, we recorded a non-cash impairment of $11.0 million against hardwood inventory at our Peace River mill as a result of low hardwood pulp prices.

Costs and expenses in the second quarter of 2025 were relatively flat at $368.7 million compared to $364.0 million in the same quarter of 2024 as the negative foreign exchange impacts from a weaker dollar, the non-cash impairment recognized on hardwood inventory and higher per unit fiber costs were mostly offset by lower maintenance costs due to fewer days of planned annual maintenance downtime in the second quarter of 2025.

Overall average per unit fiber costs in the second quarter of 2025 increased by approximately 11% compared to the same quarter of 2024 primarily as a result of higher per unit fiber costs at our German mills due to reduced supply. Per unit fiber costs at our Canadian mills were relatively flat in the second quarter of 2025 compared to the same quarter of 2024. For the third quarter of 2025, we currently expect per unit fiber costs to be lower for our German pulp mills due to reduced demand and relatively stable for our Canadian pulp mills.

Transportation costs for our pulp segment in the second quarter of 2025 were relatively flat at $32.9 million compared to $33.7 million in the same quarter of 2024.

In the second quarter of 2025, Segment Operating EBITDA for our pulp segment decreased to negative $10.3 million from positive $31.7 million in the same quarter of 2024 as a result of lower pulp sales realizations, negative foreign exchange impacts from a weaker dollar, the non-cash impairment recognized on hardwood inventory and higher per unit fiber costs. These decreases were partially offset by lower maintenance costs due to fewer days of planned annual maintenance downtime in the second quarter of 2025.

Consolidated – Six Months Ended June 30, 2025 Compared to Six Months Ended June 30, 2024

Total revenues for the first half of 2025 decreased by approximately 9% to $960.5 million from $1,052.8 million in the same period of 2024 driven by lower sales volumes and realizations from our pulp and manufactured products partially offset by higher lumber sales realizations.

Costs and expenses in the first half of 2025 decreased by approximately 8% to $1,012.2 million from $1,097.0 million in the same period of 2024 primarily as a result of lower pulp sales volumes. This decrease was partially offset by higher per unit fiber costs, foreign exchange losses and the non-cash impairment recognized against hardwood inventory at our Peace River mill in 2025. The foreign exchange losses resulted from the impact of a weaker dollar on the revaluation of dollar denominated accounts receivables held at our operations. In the first half of 2024, costs and expenses included a non-cash goodwill impairment of $34.3 million related to the Torgau facility, which was recognized as a result of ongoing weakness in lumber, pallet and biofuels markets in Europe stemming from high interest rates and other economic conditions, and a non-cash loss of $23.6 million in connection with the dissolution of the CPP joint venture.

In the first half of 2025, cost of sales depreciation and amortization was relatively steady at $77.7 million compared to $80.2 million in the same period of 2024.

Selling, general and administrative expenses were flat at $60.1 million in the first half of 2025 compared to $61.5 million in the same period of 2024.

In the first half of 2025, we had a negative foreign exchange impact of approximately $12.0 million on operating loss compared to the same period of 2024 primarily due to foreign exchange losses on the revaluation of dollar denominated accounts receivables held at our operations as the dollar weakened relative to the euro and Canadian dollar at the end of June 2025.

In the first half of 2025, our operating loss was $51.7 million compared to $44.2 million in the same period of 2024 as a result of higher per unit fiber costs, lower pulp and manufactured products sales realizations, negative foreign exchange impacts from a weaker dollar and the non-cash impairment recognized against hardwood inventory partially offset by higher lumber sales realizations. In the first half of 2024, our operating loss included a non-cash goodwill impairment of $34.3 million related to the Torgau facility and a non-cash loss of $23.6 million recognized in connection with the dissolution of the CPP joint venture.

Interest expense in the first half of 2025 was relatively flat at $56.6 million compared to $54.4 million in the same period of 2024.

In the first half of 2025, other expenses were $1.3 million compared to other income of $9.2 million in the same period of 2024. Other expenses in the first half of 2025 primarily consisted of foreign exchange losses on the revaluation of dollar denominated cash held at our operations as the dollar weakened against the euro at the end of June 2025 mostly offset by interest earned on cash. In the first half of 2024, other income primarily consisted of interest earned on cash and foreign exchange gains on the revaluation of dollar denominated cash held at our operations as the dollar strengthened at the end of June 2024.

During the first half of 2025, we had an income tax recovery of $1.1 million, or an effective tax rate of 1%, and in the same period of 2024, we had an income tax recovery of $5.1 million, or an effective tax rate of 6%. Our effective tax rates were different from the statutory rates of the jurisdictions in which we operate as we do not recognize tax

recoveries for certain entities which we do not expect to realize a tax benefit. In the first half of 2024, the effective tax rate was also impacted by the non-deductibility of the non-cash goodwill impairment.

In the first half of 2025, our net loss was $108.4 million, or $1.62 per share, compared to $84.3 million, or $1.26 per share in the same period of 2024. The net loss in the first half of 2024 included the non-cash goodwill impairment of $34.3 million, or $0.51 per share, and the non-cash loss of $23.6 million, or $0.35 per share, recognized in connection with the dissolution of the CPP joint venture.

In the first half of 2025, Operating EBITDA decreased to $26.2 million from $94.0 million in the same period of 2024 primarily due to higher per unit fiber costs, lower pulp and manufactured products sales realizations, negative foreign exchange impacts from a weaker dollar and the non-cash impairment recognized on hardwood inventory partially offset by higher lumber sales realizations.

In the six months ended June 30, 2024, financing activities used cash of $46.5 million. In the six months ended June 30, 2024, we repaid approximately $35.8 million under our revolving credit facilities and we paid dividends of $5.0 million.

Balance Sheet Data

The following table is a summary of selected financial information as of the dates indicated:

June 30,<br>2025 December 31,<br>2024
(in thousands)
Cash and cash equivalents $ 146,499 $ 184,925
Working capital $ 635,485 $ 653,466
Total assets $ 2,378,376 $ 2,262,932
Long-term liabilities $ 1,629,767 $ 1,576,619
Total shareholders’ equity $ 446,491 $ 429,775

Sources and Uses of Funds

Our principal sources of funds are cash flows from operations and cash and cash equivalents on hand. Our principal uses of funds consist of operating expenditures, capital expenditures and interest payments on our senior notes.

The following table sets out our total capital expenditures and interest expense for the periods indicated:

Six Months Ended<br>June 30,
2025 2024
(in thousands)
Capital expenditures $ 44,413 $ 36,344
Cash paid for interest expense(1) $ 53,415 $ 51,529
Interest expense(2) $ 56,566 $ 54,402
  • Amounts differ from interest expense, which includes non-cash items. See supplemental disclosure of cash flow information in our Interim Consolidated Statements of Cash Flows included in this report.
  • Interest on our senior notes due 2028 is paid semi-annually in April and October of each year. Interest on our senior notes due 2029 is paid semi-annually in February and August of each year. Prior to their redemption in October 2024, interest on our senior notes due 2026 was paid semi-annually in January and July of each year.

As of June 30, 2025, we had cash and cash equivalents of $146.5 million, approximately $291.6 million available under our revolving credit facilities and aggregate liquidity of about $438.1 million.

We have reduced our planned capital expenditures for fiscal 2025 and currently expect them to be between $90.0 million to $100.0 million.

We currently consider the majority of undistributed earnings of our foreign subsidiaries to be indefinitely reinvested and, accordingly, no U.S. income tax has been provided on such earnings. However, if we were required to repatriate funds to the U.S., we believe that we currently could repatriate the majority thereof without incurring any material amount of taxes as a result of our shareholder advances and U.S. tax reform. However, it is currently not practical to estimate the income tax liability that might be incurred if such earnings were remitted to the U.S. Substantially all of our undistributed earnings are held by our foreign subsidiaries outside of the U.S.

Based upon the current level of operations and our current expectations for future periods in light of the current economic environment, and in particular, current and expected pulp and lumber pricing and foreign exchange rates, we believe that cash flow from operations and available cash, together with available borrowings under our revolving credit facilities, will be adequate to finance the capital requirements for our business.

FORM 10-Q

QUARTERLY REPORT - PAGE 39

In the future we may make acquisitions of businesses or assets or commitments to additional capital projects. To achieve the long-term goals of expanding our assets and earnings, including through acquisitions, capital resources will be required. Depending on the size of a transaction, the capital resources that will be required can be substantial. The necessary resources will be generated from cash flow from operations, cash on hand, borrowing against our assets or the issuance of securities.

Debt Covenants

Certain of our long-term obligations contain various financial tests and covenants customary to these types of arrangements. See our annual report on Form 10-K for the fiscal year ended December 31, 2024.

As of June 30, 2025, we were in full compliance with all of the covenants of our indebtedness.

Contractual Obligations and Commitments

There were no material changes outside the ordinary course to any of our material contractual obligations during the six months ended June 30, 2025.

Foreign Currency

As a majority of our assets, liabilities and expenditures are held or denominated in euros or Canadian dollars, our consolidated financial results are subject to foreign currency exchange rate fluctuations.

We translate foreign denominated assets and liabilities into dollars at the rate of exchange on the balance sheet date. Equity accounts are translated using historical exchange rates. Unrealized gains or losses from these translations are recorded in other comprehensive income (loss) and do not affect our net earnings.

As a result of a weaker dollar versus the euro and Canadian dollar as of June 30, 2025, during the six months ended June 30, 2025, we recorded a non-cash increase of $133.6 million in the carrying value of our net assets denominated in euros and Canadian dollars, consisting primarily of our property, plant and equipment. This non-cash increase does not affect our net loss, Operating EBITDA or cash but is reflected in our other comprehensive income (loss) and as an increase to our total equity. As a result, our accumulated other comprehensive loss decreased to $97.7 million.

Based upon the exchange rate as of June 30, 2025, the dollar was approximately 5% weaker against the Canadian dollar and 13% weaker against the euro since December 31, 2024. See “Quantitative and Qualitative Disclosures about Market Risk”.

Critical Accounting Policies

The preparation of financial statements and related disclosures in conformity with GAAP requires management to make estimates and assumptions that affect both the amount and the timing of the recording of assets, liabilities, revenues, and expenses in the consolidated financial statements and accompanying note disclosures. Our management routinely makes judgments and estimates about the effects of matters that are inherently uncertain. As the number of variables and assumptions affecting the probable future resolution of the uncertainties increases, these judgments become even more subjective and complex.

Our significant accounting policies are disclosed in Note 1 to our audited annual financial statements included in our annual report on Form 10-K for the fiscal year ended December 31, 2024. While all of the significant accounting policies are important to the consolidated financial statements, some of these policies may be viewed as having a high degree of judgment. On an ongoing basis using currently available information, management reviews its estimates, including those related to accounting for, among other things, future cash flows associated with impairment testing for goodwill and long-lived assets, depreciation and amortization, pension and other post-retirement benefit obligations, deferred income taxes (valuation allowance and permanent reinvestment), the allocation of the purchase price in a business combination to the assets acquired and liabilities assumed, revenues under long-term contracts, inventory impairment, assets and liabilities classified as held for sale and the fair value of disposal groups, legal liabilities and contingencies. Actual results could differ materially from these estimates and changes in these estimates are recorded when known.

Cautionary Statement Regarding Forward-Looking Information

The statements in this report that are not reported financial results or other historical information are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, as amended.

Generally, forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts. They often include words such as “expects”, “anticipates”, “intends”, “plans”, “believes”, “seeks”, “estimates”, or words of similar meaning, or future or conditional verbs, such as “will”, “should”, “could”, or “may”, although not all forward-looking statements contain these identifying words. Forward-looking statements are based on expectations, forecasts and assumptions by our management and involve a number of risks, uncertainties and other factors, many of which are beyond our control, that could cause actual conditions, events or results to differ significantly from those described in the forward-looking statements. These factors include, but are not limited to, the following:

Risks Related to our Business

  • Our business is highly cyclical in nature;
  • cyclical fluctuations in the price and supply of our raw materials, particularly fiber, could adversely affect our business;
  • inflation or a sustained increase in our key production and other costs would lead to higher manufacturing costs which could reduce our margins;
  • our business, financial condition and results of operations could be adversely affected by disruptions in the global and European economies caused by geopolitical conflicts, including Russia's invasion of Ukraine and conflicts in the Middle East;
  • the impacts of changes in international trade policies, including tariffs or other trade barriers by the United States, or other nations, may adversely impact our business, financial condition and results of operations;

  • acquisitions may result in additional risks and uncertainties in our business;
  • our operations require substantial capital and we may be unable to maintain adequate capital resources to provide for such capital requirements;
  • trends in non-print media and changes in consumer habits regarding the use of paper have and are expected to continue to adversely affect the demand for market pulp;
  • we are subject to risks related to our employees;
  • we are dependent on key personnel;

FORM 10-Q

QUARTERLY REPORT - PAGE 41

  • if our long-lived assets become impaired, we may be required to record non-cash impairment charges that could have a material impact on our results of operations;
  • our insurance coverage may not be adequate;
  • we rely on third parties for transportation services;
  • if we are unable to offer products certified to globally recognized forestry management and chain of custody standards or meet customers’ product or project specifications, it could adversely affect our ability to compete;
  • failures or security breaches of our information technology systems could disrupt our operations and negatively impact our business;
  • evolving sustainability reporting and environmental, social and governance preferences of customers, investors and other stakeholders may impact our business;

Risks Related to our Debt

  • our level of indebtedness could negatively impact our financial condition, results of operations and liquidity;
  • changes in credit ratings issued by nationally recognized statistical rating organizations could adversely affect our cost of financing and have an adverse effect on the market price of our securities;
  • we are exposed to interest rate fluctuations;

Risks Related to Macroeconomic Conditions

  • a weakening of the global economy, including capital and credit markets, could adversely affect our business and financial results and have a material adverse effect on our liquidity and capital resources;
  • political uncertainty, an increase in trade protectionism or geopolitical conflict could have a material adverse effect on global macroeconomic activities and trade and adversely affect our business, results of operations and financial condition;
  • we are exposed to currency exchange rate fluctuations;
  • globally, various central banks raised interest rates in 2022 and 2023 in response to high inflation rates, leading to a relatively high-interest rate environment, which could dampen macroeconomic conditions and business activity and reduce demand for our products;
  • health epidemics or pandemics could adversely affect our business and financial results;
  • we may incur losses as a result of unforeseen or catastrophic events, including terrorist attacks or natural disasters;

Legal and Regulatory Risks

  • we are subject to extensive environmental regulation and we could incur substantial costs as a result of compliance with, violations of or liabilities under applicable environmental laws and regulations;
  • we sell surplus green energy in Germany and are subject to changing energy legislation in response to high prices and energy shortages;
  • our international sales and operations are subject to applicable laws relating to trade, export controls, foreign

FORM 10-Q

QUARTERLY REPORT - PAGE 42

  • corrupt practices and competition laws, the violation of which could adversely affect our operations;
  • product liability claims could adversely affect our operating results;

Risks Related to Ownership of our Shares

  • the price of our common stock may be volatile; and
  • a small number of our shareholders could significantly influence our business.

Given these uncertainties, you should not place undue reliance on our forward-looking statements. The foregoing review of important factors is not exhaustive or necessarily in order of importance and should be read in conjunction with the risks and assumptions including those set forth under “Item 1A. Risk Factors” in our annual report on Form 10-K for the fiscal year ended December 31, 2024 and in the other reports and documents we have filed with or furnished to the SEC. We advise you that these cautionary remarks expressly qualify in their entirety all forward-looking statements attributable to us or persons acting on our behalf. Unless required by law, we do not assume any obligation to update forward-looking statements based on unanticipated events or changed expectations. However, you should carefully review the reports and other documents we file from time to time with the SEC.

Cyclical Nature of Business

Revenues

The pulp and lumber businesses are highly cyclical in nature and markets are characterized by periods of supply and demand imbalance, which in turn can materially affect prices. Pulp and lumber markets are sensitive to cyclical changes in the global economy, industry capacity and foreign exchange rates, all of which can have a significant influence on selling prices and our operating results. The length and magnitude of industry cycles have varied over time but generally reflect changes in macroeconomic conditions and levels of industry capacity. Pulp and lumber are commodities that are generally available from other producers. Because commodity products have few distinguishing qualities from producer to producer, competition is generally based upon price, which is primarily determined by supply relative to demand.

Industry capacity can fluctuate as changing industry conditions can influence producers to idle production capacity or permanently close mills. In addition, to avoid substantial cash costs in idling or closing a mill, some producers will choose to operate at a loss, sometimes even a cash loss, which can prolong weak pricing environments due to oversupply. Oversupply of our products can also result from producers introducing new capacity in response to favorable pricing trends. Certain integrated pulp and paper producers have the ability to discontinue paper production by idling their paper machines and selling their pulp production on the market, if market conditions, prices and trends warrant such actions.

Demand for each of pulp and lumber has historically been determined primarily by general global macroeconomic conditions and has been closely tied to overall business activity. Pulp and lumber prices have been and are likely to continue to be volatile and can fluctuate widely over time.

The third-party industry quoted average European list prices for NBSK pulp between 2016 and 2025 have fluctuated between a low of $790 per ADMT in 2016 to a high of $1,635 per ADMT in 2024. In the same period, third-party industry quoted average North American list prices for NBHK pulp have fluctuated between a low of $820 per ADMT in 2016 to a high of $1,620 per ADMT in 2022.

As a key construction material, the pricing and demand for lumber is also significantly influenced by the number of housing starts, especially in the U.S. In the U.S., third-party industry quoted monthly average western spruce/pine/fir (WSPF) 2 x 4 #2&Btr prices between 2016 and 2025 have fluctuated between a low of $259 per Mfbm in 2016 to a high of $1,604 per Mfbm in 2021. Similarly, the demand for CLT and glulam is primarily driven by the wood construction market and increased government policies focused on a low-carbon economy.

FORM 10-Q

QUARTERLY REPORT - PAGE 43

Our mills and operations voluntarily subject themselves to third-party certifications in compliance with internationally recognized, sustainable management standards because end use paper and lumber customers have shown an increased interest in understanding the origin of products they purchase. Demand for our products could be adversely affected if we, or our suppliers, are unable to achieve compliance, or are perceived by the public as failing to comply, with these standards or if our customers require compliance with alternate standards for which our operations are not certified.

A pulp producer's actual sales price realizations are net of customer discounts, rebates and other selling concessions. Accordingly, prices for pulp and lumber are driven by many factors outside our control, and we have little influence over the timing and extent of price changes, which are often volatile. Because market conditions beyond our control determine the prices for pulp and lumber, prices may fall below our cash production costs, requiring us to either incur short-term losses on product sales or cease production at one or more of our mills. Therefore, our profitability depends on managing our cost structure, particularly raw materials which represent a significant component of our operating costs and can fluctuate based upon factors beyond our control. If the prices of our products decline, or if prices for our raw materials increase, or both, our results of operations and cash flows could be materially adversely affected.

Costs

Our production costs are influenced by the availability and cost of raw materials, energy and labor, and our plant efficiencies and productivity. Our main raw material is fiber in the form of wood chips, pulp logs, sawlogs and lumber. Wood chip, pulp log and sawlog costs are primarily affected by the supply of, and demand for, lumber and pulp, which are both highly cyclical. Higher fiber prices could affect producer profit margins if they are unable to pass along price increases to pulp and lumber customers or purchasers of surplus energy.

Currency

We have manufacturing operations in Germany, Canada and the U.S. Most of the operating costs and expenses of our German mills are incurred in euros and those of our Canadian mills in Canadian dollars. However, the majority of our sales are in products quoted in dollars. Our results of operations and financial condition are reported in dollars. As a result, our costs generally benefit from a strengthening dollar but are adversely affected by a decrease in the value of the dollar relative to the euro and to the Canadian dollar. Such declines in the dollar relative to the euro and the Canadian dollar reduce our operating margins and the cash flow available to fund our operations and to service our debt. This could have a material adverse effect on our business, financial condition, results of operations and cash flows.

FORM 10-Q

QUARTERLY REPORT - PAGE 44

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risks from changes in interest rates and foreign currency exchange rates, particularly the exchange rates between the dollar and the euro and Canadian dollar. Changes in these rates may affect our results of operations and financial condition and, consequently, our fair value. We seek to manage these risks through internal risk management policies as well as the periodic use of derivatives.

For additional information, please refer to “Item 7A. Quantitative and Qualitative Disclosures about Market Risk” in our annual report on Form 10-K for the fiscal year ended December 31, 2024.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, referred to as the “Exchange Act”), as of the end of the period covered by this report. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is accumulated and communicated to management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Based on such evaluation, our principal executive officer and principal financial officer have concluded that, as of the end of the period covered by this report, our disclosure controls and procedures are effective in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by us in the reports that we file or submit under the Exchange Act.

It should be noted that any system of controls is based in part upon certain assumptions designed to obtain reasonable (and not absolute) assurance as to its effectiveness and there can be no assurance that any design will succeed in achieving its stated goals.

Changes in Internal Controls

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
