Notes to Consolidated Financial Statements (Unaudited)

(in thousands unless otherwise stated)

1. Basis of Presentation

The unaudited consolidated financial statements and notes thereto of the Company have been prepared in accordance with GAAP for interim financial information and in accordance with the rules and regulations of the SEC. In the opinion of management, these consolidated financial statements and notes reflect all adjustments, including all normal recurring adjustments, necessary for a fair presentation of the results of operations, financial position and cash flows for the periods presented. These statements and notes should be read in conjunction with the consolidated financial statements and supplementary data included in the Company’s 2022 Form 10-K.

As a result of the sale of its lumber and newsprint assets in August 2021, the Company presents the results for those operations and any associated impacts as discontinued operations. Unless otherwise stated, information in these notes to consolidated financial statements relates to continuing operations. See Note 2—Discontinued Operations for further information on the sale.

Recent Accounting Developments

There have been no new or recently adopted accounting pronouncements impacting the Company’s consolidated interim financial statements.

Subsequent Events

The Company recently began plans towards a realignment of its High Purity Cellulose assets to optimize production mix, including a consolidation of its commodity products production into the Temiscaming plant. The Company is currently evaluating the potential impact of this realignment on its consolidated financial statements and disclosures.

2. Discontinued Operations

In August 2021, the Company completed the sale of its lumber and newsprint facilities and certain related assets located in Canada to GreenFirst for $232 million, which included 28.7 million shares of GreenFirst common stock with a deemed fair value of $42 million. In the second quarter of 2022, the Company sold the GreenFirst common shares for $43 million. Prior to the sale of shares, the GreenFirst common shares were accounted for at fair value, with changes in fair value recorded in the consolidated statements of operations. The shares sale agreement contains a purchase price protection clause whereby the Company is entitled to participate in further share price appreciation under certain circumstances until December 2023.

As part of the sale of the lumber assets, the Company retained all rights and obligations to softwood duties generated or incurred through the closing date of the sale. In total, the Company paid $112 million in softwood lumber duties from 2017 through August 2021, and expects to receive all or the vast majority of these duties upon final resolution of the dispute between the USDOC and Canada. During the third quarter of 2023, the USDOC completed its fourth administrative review of duties applied to Canada softwood lumber exports to the U.S. during 2021 and reduced rates applicable to the Company to a combined 8.05 percent. In connection with this development, the Company recorded a pre-tax gain of $2 million in “income from discontinued operations, net of taxes” and increased the long-term receivable related to USDOC administrative reviews to $40 million. During the third quarter of 2022, the USDOC completed its third administrative review of duties applied to Canada softwood lumber exports during 2020 and reduced applicable rates to a combined 8.6 percent, for which the Company recorded a pre-tax gain of $16 million.

During the nine months ended September 30, 2023, the Company incurred a $2 million loss related to the settlement of a claim pursuant to the representations and warranties in the asset purchase agreement.

As of September 30, 2023, the Company’s leases have remaining lease terms of less than one year to 13.1 years with standard renewal and termination options available at the Company’s discretion. Certain equipment leases have purchase options at the end of the term of the lease, which are not included in the ROU assets, as it is not reasonably certain that the Company will exercise such options. The Company’s lease agreements do not contain any material residual value guarantees or restrictive covenants. The Company uses its incremental borrowing rate in determining the present value of lease payments unless the lease provides an implicit or explicit interest rate.

Term Loan

In July 2023, the Company secured term loan financing of $250 million in aggregate principal amount and received net proceeds of $243 million after original issue discount. In addition, the Company incurred issuance costs of $10 million, which, together with the original issue discount, were recorded in “long-term debt” in the consolidated balance sheets and will be amortized to “interest expense” in the consolidated statements of operations over the term of the loan. The net proceeds, together with cash on hand, were used to redeem the 2024 Notes and pay transaction costs.

The 2027 Term Loan matures in July 2027, bears interest at an annual rate equal to three-month Term SOFR (or, if greater, 3.00 percent) plus 8.00 percent and requires quarterly principal payments of $1.25 million. The Company may voluntarily make prepayments at any time, subject to customary breakage costs and, if within the first three anniversaries of closing, an additional make-whole premium.

(in thousands unless otherwise stated)

The agreement governing the 2027 Term Loan contains various customary covenants that limit the ability of the Company and its restricted subsidiaries, as defined by the term loan agreement and in particular the Company’s French subsidiaries, to take certain specified actions, subject to stated exceptions, including: incurring debt or liens, making investments, entering into mergers, consolidations, and acquisitions, paying dividends and making other restricted payments. The Company will be required to maintain a consolidated secured net leverage ratio, based on covenant EBITDA, of no greater than 4.50 to 1.00. Additionally, the 2027 Term Loan contains customary affirmative covenants and customary events of default (subject, in certain cases, to customary grace or cure periods), including, without limitation, late payment, breach of covenant, bankruptcy, judgment and defaults under certain other indebtedness and changes in control.

Senior Notes

2026 Notes

In April 2023, the Company repurchased $10 million of its 2026 Notes through open-market transactions and retired the notes for cash of $9 million. A gain on extinguishment of $1 million for the repurchase was recorded to “other income, net” in the consolidated statements of operations.

2024 Notes

In August 2023, the Company redeemed the $318 million principal balance and accrued interest of $4 million of the 2024 Notes. A loss on extinguishment of $1 million related to the redemption was recorded to “other income, net” in the consolidated statements of operations.

Prior to the full redemption of its 2024 Notes, in March 2023, the Company repurchased $5 million of the 2024 Notes through open-market transactions and retired the notes for cash of $5 million. An immaterial gain on extinguishment for the repurchase was recorded to “other income, net” in the consolidated statements of operations.

As of September 30, 2023, the Company’s debt principal payments, excluding finance lease obligations, were due as follows:


Remainder of 2023	$	5,597
2024	16,345
2025	16,392
2026	480,320
2027	243,071
Thereafter	6,490
Total debt principal payments	$	768,215

8. Environmental Liabilities

The Company’s environmental liabilities balance changed as follows during the nine months ended September 30, 2023:


Balance at December 31, 2022	$	170,681
Increase in liabilities	2,462
Payments	(3,634)
Foreign currency adjustments	85
Balance at September 30, 2023	169,594

Notes to Consolidated Financial Statements (Unaudited)

(in thousands unless otherwise stated)

In addition to these estimated liabilities, the Company is subject to the risk of reasonably possible additional liabilities in excess of the established reserves due to potential changes in circumstances and future events, including, without limitation, changes to current laws and regulations; changes in governmental agency personnel, direction, philosophy or enforcement policies; developments in remediation technologies; increases in the cost of remediation, operation, maintenance and monitoring of its environmental liability sites; changes in the volume, nature or extent of contamination to be remediated or monitoring to be undertaken; the outcome of negotiations with governmental agencies or non-governmental parties; and changes in accounting rules or interpretations. Based on information available as of September 30, 2023, the Company estimates this exposure could range up to approximately $85 million, although no assurances can be given that this amount will not be exceeded given the factors described above. These potential additional costs are attributable to several sites and other applicable liabilities. This estimate excludes liabilities that would otherwise be considered reasonably possible but for the fact that they are not currently estimable, primarily due to the factors discussed above.

Subject to the previous paragraph, the Company believes its estimates of liabilities are sufficient for probable costs expected to be incurred over the next 20 years with respect to its environmental liabilities. However, no assurances are given that these estimates will be sufficient for the reasons described above and additional liabilities could have a material adverse effect on the Company’s financial position, results of operations and cash flows.

9. Fair Value Measurements

The following table presents the carrying amount, estimated fair values and categorization under the fair value hierarchy for financial instruments held by the Company, using market information and what management believes to be appropriate valuation methodologies:


	September 30, 2023						December 31, 2022
	Carrying Amount		Fair Value				Carrying Amount		Fair Value
			Level 1		Level 2				Level 1		Level 2
Assets
Cash and cash equivalents
Cash	$	17,484	$	17,484	$	—	$	127,288	$	127,288	$	—
Money market and similar funds	9,643		9,643		—		24,515		24,515		—

Liabilities
Fixed-rate long-term debt(a)	$	513,004	$	—	$	439,787	$	847,591	$	—	$	838,502

(a)Excludes finance lease obligations.

The Company uses the following methods and assumptions in estimating the fair value of its financial instruments:

Cash and cash equivalents — Cash and cash equivalents are highly liquid investments purchased with an original or remaining maturity of three months or less at the date of purchase and the carrying amount is equal to fair market value. The Company measures its investments in money market and similar funds using level 1 inputs.

Debt — The fair value of fixed rate debt is based upon quoted market prices for debt with similar terms and maturities. Variable rate debt adjusts with changes in the market rate and so carrying value approximates fair value.

(b)Reclassifications of foreign currency exchange contracts are recorded in “cost of sales,” “other operating expense, net” or “other income, net,” as appropriate.

(c)Foreign currency translation is net of tax effects of $0 for all periods presented, as the French operations are taxed on the foreign functional currency, not the translated reporting currency.

11. Stockholders’ Equity

Stockholder Rights Plan

In March 2022, the Company adopted a stockholder rights plan whereby a significant penalty is imposed upon any person or group which acquires beneficial ownership of 10% or more of the Company’s common stock without the approval of the Board of Directors. On the same date, the Board of Directors declared a dividend of one preferred share Purchase Right for each outstanding share of common stock of the Company, par value $0.01 per share, which was paid to Company stockholders of record as of March 31, 2022. On March 20, 2023, the Purchase Rights expired.

13. Incentive Stock Plans

Stock-based compensation expense was as follows:


	Three Months Ended				Nine Months Ended
	September 30, 2023		September 24, 2022		September 30, 2023		September 24, 2022
Stock-based compensation expense	$	1,990	$	1,959	$	5,361	$	8,687

The Company made new grants of restricted stock units, performance-based stock units and performance-based cash awards during the first and second quarters of 2023. The 2023 restricted stock unit awards cliff vest after three years. The 2023 performance-based awards cliff vest after three years and are based equally on TSR relative to peers and three-year cumulative adjusted EBITDA. Participants can earn between 0 and 200 percent of the target award. Performance below the threshold for the TSR would result in zero payout for the TSR metric. The performance-based cash award is measured using the same objectives as the performance-based stock unit award but is paid and accounted for separately. Performance-based cash awards are classified as a liability and remeasured to fair value at the end of each reporting period until settlement.

In March 2023, the performance-based stock units granted in 2020 were settled with the issuance of 1,257,015 shares of common stock, including incremental shares of 370,366, based on performance results.

14. Employee Benefit Plans

Defined Benefit Plans

The Company has defined benefit pension and other long-term and postretirement benefit plans covering certain union and non-union employees, primarily in the U.S. and Canada. The defined benefit pension plans are closed to new participants. The liabilities for these plans are calculated using actuarial estimates and management assumptions. These estimates are based on historical information and certain assumptions about future events.

During the nine months ended September 24, 2022, the Company recorded a $1 million loss related to the final asset surplus distribution to the plan participants of certain wound-up Canadian pension plans. During the nine months ended September 30, 2023, the Company recorded a $2 million loss related to the final asset surplus distribution to the plan participants of certain other wound-up Canadian pension plans. The settlements were recognized in “other components of pension and OPEB, excluding service costs” in the Company’s consolidated statements of operations.

The following tables present the components of net periodic benefit costs of these plans:


	Pension				Postretirement

Service cost is included in “cost of sales” or “selling, general and administrative expense” in the consolidated statements of operations, as appropriate. Interest cost, expected return on plan assets, amortization of prior service cost (credit) and amortization of (gain) loss are included in “other components of pension and OPEB, excluding service costs” in the consolidated statements of operations.

15. Income Taxes

Effective Tax Rate

The Company’s effective tax rates were as follows:


	Three Months Ended						Nine Months Ended
	September 30, 2023			September 24, 2022			September 30, 2023			September 24, 2022
Income (loss) from continuing operations	$	(26,540)		$	18,355		$	(40,555)		$	(30,969)
Effective tax rate	17.0		%	(10.6)		%	22.4		%	(12.6)		%

The 2023 effective tax rates differed from the federal statutory rate of 21 percent primarily due to disallowed interest deductions in the U.S. and nondeductible executive compensation, offset by U.S. tax credits, return-to-accrual adjustments related to previously filed tax returns, changes in the valuation allowance on disallowed interest deductions and interest received on overpayments of tax from prior years. The effective tax rate for the nine-month period was also impacted by an excess tax benefit on vested stock compensation.

The effective tax rate for the three months ended September 24, 2022 differed from the federal statutory rate of 21 percent primarily due to changes in the valuation allowance on disallowed interest deductions in the U.S. and interest received on overpayments of tax from prior years, partially offset by unfavorable tax return-to-accrual adjustments. The effective tax rate for the nine months ended September 24, 2022 differed from the federal statutory rate primarily due to changes in the valuation allowance on disallowed interest deductions in the U.S. and nondeductible executive compensation, partially offset by interest received on overpayments of tax from prior years, U.S. tax credits and favorable tax return-to-accrual adjustments.

Deferred Taxes

As of both September 30, 2023 and December 31, 2022, the Company’s net DTA included $17 million of disallowed U.S. interest deductions that the Company does not believe will be realized. In strict compliance with the American Institute of Certified Public Accountants’ Technical Questions and Answers 3300.01-02, which asserts that certain material evidence regarding the realizability of disallowed U.S. interest deductions should be ignored when assessing the need for a valuation allowance, the Company has not recognized a valuation allowance on this portion of the net DTA generated from disallowed interest.

16. Segments

The Company operates in the following business segments: High Purity Cellulose, Paperboard and High-Yield Pulp. Corporate consists primarily of senior management, accounting, information systems, human resources, treasury, tax and legal administrative functions that provide support services to the operating business units. The Company allocates a portion of the cost of maintaining these support functions to its operating units.

The Company evaluates the performance of its segments based on operating income (loss). Intersegment sales consist primarily of High-Yield Pulp sales to Paperboard. Intersegment sales prices are at rates that approximate market for the respective operating area.

17. Commitments and Contingencies

Commitments

The Company had no material changes to the purchase obligations presented in its 2022 Form 10-K that were outside the normal course of business during the nine months ended September 30, 2023. The Company’s purchase obligations continue to primarily consist of commitments for the purchase of natural gas, steam energy and wood chips.

The Company leases certain buildings, machinery and equipment under various operating and finance leases. See Note 5—Leases for further information.

Litigation and Contingencies

Duties on Canadian Softwood Lumber Sold to the U.S.

The Company previously operated six softwood lumber mills in Ontario and Quebec, Canada, and exported softwood lumber into the U.S. from Canada. In connection with these exports, the Company paid approximately $112 million for softwood lumber duties between 2017 and August 28, 2021, including $1 million of ancillary fees, which were recorded as expense in the periods incurred. As part of the sale of its lumber assets, the Company retained all rights and obligations to softwood duties generated or incurred through the closing date of the sale. As of September 30, 2023, the Company had a $40 million long-term receivable associated with the USDOC’s determinations of the revised rates for the 2017, 2018, 2019, 2020 and 2021 periods. This amount does not include interest, which will be due on any amounts refunded. The Company estimates interest earned on the total amount of softwood lumber duties paid to be approximately $6 million.

Cash is not expected to return to the Company until final resolution of the softwood lumber dispute, which remains subject to legal challenges.

Other

In addition to the above, the Company is engaged in various legal and regulatory actions and proceedings and has been named as a defendant in various lawsuits and claims arising in the ordinary course of business. While the Company has procured reasonable and customary insurance covering risks normally occurring in connection with its businesses, the Company has, in certain cases, retained some risk through the operation of self-insurance, primarily in the areas of workers’ compensation, property insurance, business interruption and general liability. These other lawsuits and claims, either individually or in the aggregate, are not expected to have a material adverse effect on the Company’s financial position, results of operations or cash flows.

Guarantees and Other

The Company provides financial guarantees as required by creditors, insurance programs and various governmental agencies. As of September 30, 2023, the Company had net exposure of $34 million from various standby letters of credit, primarily for financial assurance relating to environmental remediation, credit support for natural gas and electricity purchases and guarantees related to foreign retirement plan obligations. These standby letters of credit represent a contingent liability; the Company would only be liable upon its default on the related payment obligations. The standby letters of credit have various expiration dates and are expected to be renewed as required.

The Company had surety bonds of $90 million as of September 30, 2023, primarily to comply with financial assurance requirements relating to environmental remediation and post closure care, to provide collateral for the Company’s workers’ compensation program and to guarantee taxes and duties for products shipped internationally. These surety bonds expire at various dates and are expected to be renewed annually as required.

LTF is a venture in which the Company owns 45 percent and its partner, Borregaard ASA, owns 55 percent. The Company is a guarantor of LTF’s financing agreements and, in the event of default, expects it would only be liable for its proportional share of any repayment under the agreements. The Company’s proportion of the LTF financing agreement guarantee was $29 million at September 30, 2023.

The Company has not recorded any liabilities for these financial guarantees in its consolidated balance sheets, either because the Company has recorded the underlying liability associated with the guarantee or the guarantee is dependent on the Company’s own performance and, therefore, is not subject to the measurement requirements or because the Company has calculated the estimated fair value of the guarantee and determined it to be immaterial based upon the current facts and circumstances that would trigger a payment obligation.

It is not possible to determine the maximum potential amount of liability under these potential obligations due to the unique set of facts and circumstances likely to be involved with each provision.

As of December 31, 2022, a collective bargaining agreement covering approximately 575 unionized employees was expired. The employees continued to work under the terms of the expired contract until negotiations concluded in the second quarter of 2023 and final agreement with the union was reached. As of September 30, 2023, all of the Company’s collective bargaining agreements covering its unionized employees were current.

Business Overview

We are a global leader of specialty cellulose materials with a broad offering of high purity cellulose specialties, a natural polymer used in the production of a variety of specialty chemical products, including liquid crystal displays, filters, textiles and performance additives for pharmaceutical, food and other industrial applications. Building upon more than 95 years of experience in cellulose chemistry, we provide some of the highest quality high-purity cellulose pulp products that make up the essential building blocks for our customers’ products while providing exceptional service and value. We also produce a unique, lightweight multi-ply paperboard product and a bulky, high-yield pulp product. Our paperboard is used for production in the commercial printing, lottery ticket and high-end packaging sectors. Our high-yield pulp is used by paperboard producers, as well as in traditional printing, writing and specialty paper manufacturing.

We operate in the following business segments: High Purity Cellulose, Paperboard and High-Yield Pulp.

Recent Business Developments

•In July 2023, we secured term loan financing of $250 million in aggregate principal amount, the proceeds of which were used, together with cash on hand, to redeem the $318 million principal balance of the 2024 Notes in August 2023.

•In April 2023, we repurchased $10 million of our 2026 Notes through open-market transactions and retired the notes for cash of $9 million.

•In March 2023, we repurchased $5 million of our 2024 Notes through open-market transactions and retired the notes for cash of $5 million.

Market Assessment

In October 2023, we announced that we engaged a financial advisor to explore the potential sale of our Paperboard and High-Yield Pulp assets located at our Temiscaming site. This strategic move is aligned with our commitment to enhancing our operational and financial performance, optimizing our portfolio to align with our long-term growth strategy and providing flexibility to pay down debt and reduce leverage.

Table of Contents

The following market assessment represents our best current estimate of our business segments’ future performance.

High Purity Cellulose

Average sales prices for cellulose specialties in 2023 are expected to be in the high single-digit percent higher than average 2022 sales prices, while sales volumes are expected to decrease from prior year due to softness in sales orders driven principally by significant customer destocking and market-driven demand declines. Market demand for commodity products remains resilient with fluff and viscose prices bottoming in the third quarter and a slight uptick expected in the fourth quarter. Commodity sales volumes are expected to continue to increase through the end of 2023. The prices for certain inputs have come off the 2022 highs but are expected to remain significantly elevated versus pre-COVID pandemic levels. We expect to take downtime at our Tartas facility at the end of 2023 due to market conditions and to improve working capital.

We recently began plans towards a realignment of our High Purity Cellulose assets to optimize production mix, including a consolidation of our commodity products production into the Temiscaming plant. We are currently evaluating the potential impact of this realignment on our consolidated financial statements and disclosures.

Paperboard

Paperboard prices are expected to rebound slightly in the fourth quarter, remaining elevated from 2022 levels, while sales volumes are expected to improve in the second half of the year as customer inventories return to more normal levels. Raw material prices are expected to increase slightly as purchased pulp prices are forecast to increase in the fourth quarter. We expect to take downtime in the coming quarter due to market conditions and to improve working capital.

High-Yield Pulp

High-yield pulp prices have declined due to soft demand and new paper pulp capacity ramping up. Prices are expected to decline overall in 2023 despite an expected uptick in the fourth quarter, in line with industry forecasts for the global paper pulp market. We expect to take downtime in the coming quarter due to market conditions and to improve working capital.

A Sustainable Future

Our portfolio is aligned with sustainability drivers in the European Green Deal for the Renewable Energy Directive II and the 2G bio-fuel that is noncompetitive to human food supply. The 2G bioethanol facility at our Tartas, France plant is near completion and is anticipated to be operational in the first quarter of 2024. The total estimated cost of the project is approximately $40 million, with $22 million to be spent in 2023. We plan to utilize $28 million of low-cost green loans to help fund the project, including $10 million already borrowed, and $4 million in grants. The project is expected to provide $8 million to $10 million of annual incremental EBITDA, depending on current exchange rates, beginning in 2025.

Operating results for the quarter ended September 30, 2023 declined $43 million, or 148 percent, compared to the same prior year quarter, driven by the decrease in net sales across all segments and an increase in Corporate expense items, partially offset by lower input, logistics and maintenance costs. Operating results for the nine months ended September 30, 2023 declined $14 million, or 140 percent, compared to the same prior year period, driven by lower net sales in our Paperboard segment, higher labor costs and the impact of an extended maintenance outage in the prior year, partially offset by the increase in net sales in our High Purity Cellulose and High-Yield Pulp segments, lower input and logistics costs and the recognition of a $3 million benefit from payroll tax credit carryforwards in the current period. See Operating Results by Segment below for further discussion.

Non-Operating Income & Expense

Interest expense increased $5 million and $3 million during the quarter and nine months ended September 30, 2023, respectively, compared to the same prior year periods, primarily due to an increase in the average interest rate on debt, partially offset by a decrease in the average outstanding balance of debt. Debt principal outstanding decreased $109 million from September 24, 2022 to September 30, 2023.

Interest income increased $2 million and $3 million during the quarter and nine months ended September 30, 2023, respectively, compared to the same prior year periods, primarily due to the timing of the receipt of the 2027 Term Loan proceeds and their subsequent use in the repayment of the 2024 Notes.

Also included in non-operating other income in the quarter ended September 30, 2023 was a $1 million net loss on debt extinguishment. Included in the current nine-month period was a $2 million gain on a passive land sale and a pension settlement loss of $2 million.

Included in non-operating other income in the nine months ended September 24, 2022 was a $5 million net gain associated with the GreenFirst common shares received in connection with the sale of our lumber and newsprint assets.

Income Taxes

The effective tax rate on the loss from continuing operations for the quarter and nine months ended September 30, 2023 was a benefit of 17 percent and 22 percent, respectively. The 2023 effective tax rates differed from the federal statutory rate of 21 percent primarily due to disallowed interest deductions in the U.S. and nondeductible executive compensation, offset by U.S. tax credits, return-to-accrual adjustments related to previously filed tax returns, changes in the valuation allowance on disallowed interest deductions and interest received on overpayments of tax from prior years. The effective tax rate for the nine-month period was also impacted by an excess tax benefit on vested stock compensation.

The effective tax rate on the income from continuing operations for the quarter ended September 24, 2022 was a benefit of 11 percent. The effective tax rate on the loss from continuing operations for the nine months ended September 24, 2022 was an expense of 13 percent. The 2022 effective tax rates differed from the statutory rate of 21 percent primarily due to changes in the valuation allowance on disallowed interest deductions in the U.S., nondeductible executive compensation, interest received on overpayments of tax from prior years, U.S. tax credits and tax return-to-accrual adjustments.

Liquidity and Capital Resources

Overview

Cash flows from operations, primarily driven by operating results, have historically been our primary source of liquidity and capital resources. As operating cash flows can be negatively impacted by fluctuations in market prices for our commodity products and changes in demand for our products, we maintain a key focus on cash, managing working capital closely and optimizing the timing and level of our capital expenditures.

Our Board of Directors suspended our quarterly common stock dividend in September 2019. No dividends have been declared since. The declaration and payment of future common stock dividends, if any, will be at the discretion of our Board of Directors and will be dependent upon our financial condition, results of operations, capital requirements and other factors that the Board of Directors deems relevant. In addition, our debt facilities place limitations on the declaration and payment of future dividends.

In January 2018, our Board of Directors authorized a $100 million common stock share buyback program. We did not repurchase any shares under this program during the nine months ended September 30, 2023 and September 24, 2022, and do not expect to utilize any authorization in the future.

As of September 30, 2023, we were in compliance with all financial and other customary covenants under our credit arrangements. We believe our future cash flows from operations, availability under our ABL Credit Facility and our ability to access the capital markets, if necessary or desirable, will be adequate to fund our operations and anticipated long-term funding requirements, including capital expenditures, defined benefit plan contributions and repayment of debt maturities.

Our non-guarantor subsidiaries had assets of $444 million, liabilities of $373 million, year-to-date revenue of $119 million and a trailing twelve month ABL Credit Facility and Term Loan covenant EBITDA for continuing operations of $29 million as of September 30, 2023.

(a)Consist of cash, money market deposits and time deposits with original maturities of 90 days or less.

(b)Amounts available under the ABL Credit Facility fluctuate based on eligible accounts receivable and inventory levels. At September 30, 2023, we had $146 million of gross availability and net available borrowings of $112 million after taking into account standby letters of credit of $34 million. In addition to the availability under the ABL Credit Facility, we have $8 million available under our accounts receivable factoring line of credit in France.

(c)See Note 7—Debt and Finance Leases to our Financial Statements for further information.

Cash Requirements

Contractual Commitments

Our principal contractual commitments include standby letters of credit, surety bonds, guarantees, purchase obligations and leases. We utilize arrangements such as standby letters of credit and surety bonds to provide credit support for certain suppliers and vendors in case of their default on critical obligations, collateral for certain of our self-insurance programs and guarantees for the completion of our remediation of environmental liabilities. As part of our ongoing operations, we also periodically issue guarantees to third parties. Our primary purchase obligation payments relate to natural gas, steam energy and wood chips purchase contracts. There have been no material changes to our contractual commitments outside the ordinary course of business during the nine months ended September 30, 2023. See Note 17—Commitments and Contingencies to our Financial Statements for further information.

Debt

In March 2023, we repurchased $5 million of our 2024 Notes through open-market transactions and retired the notes for cash of $5 million.

In April 2023, we repurchased $10 million of our 2026 Notes through open-market transactions and retired the notes for cash of $9 million.

In July 2023, we secured term loan financing of $250 million in aggregate principal amount and received net proceeds of $243 million after original issue discount, which was used, together with cash on hand of $89 million, to redeem the remaining $318 million in aggregate principal balance and accrued interest of $4 million of the 2024 Notes and pay fees and expenses related to the transaction. The 2027 Term Loan matures in July 2027, bears interest at an annual rate equal to three-month Term SOFR (or, if greater, 3.00 percent) plus 8.00 percent and requires quarterly principal payments of $1.25 million.

Cash Flows


	Nine Months Ended
(in millions)	September 30, 2023		September 24, 2022
Cash flows provided by (used in):
Operating activities	$	82	$	7

Investing activities-continuing operations	(95)		(114)
Investing activities-discontinued operations	—		44
Financing activities	(112)		(51)

Cash provided by operating activities increased $75 million primarily due to increased cash inflows from working capital, partially offset by payments on deferred energy liabilities associated with our Tartas facility operations and the receipt in 2022 of a $23 million U.S. federal tax refund.

Cash used in investing activities of continuing operations decreased $19 million due to lower capital spending.

Table of Contents

Cash provided by investing activities of discontinued operations of $44 million in 2022 related to the proceeds from the sale of GreenFirst equity securities.

Cash used in financing activities increased $61 million primarily due to the redemption of the 2024 Notes and repayment of borrowings under the ABL Credit Facility and other long-term debt, the payment of issuance costs related to our 2027 Term Loan and higher repurchases of common stock to satisfy tax withholding requirements related to the issuance of stock under our incentive stock plans. These outflows were partially offset by the net proceeds received from the 2027 Term Loan issuance and borrowings under the ABL Credit Facility.

Performance and Liquidity Indicators

The discussion below is presented to enhance the reader’s understanding of our operating performance, liquidity and ability to generate cash and satisfy rating agency and creditor requirements. This information includes the non-GAAP financial measures of EBITDA, adjusted EBITDA and adjusted free cash flows. These measures are not defined by GAAP and our discussion of them is not intended to conflict with or change any of our GAAP disclosures provided in this report.

We believe these non-GAAP financial measures provide useful information to our Board of Directors, management and investors regarding our financial condition and results of operations. Our management uses these non-GAAP financial measures to compare our performance to that of prior periods for trend analyses, to determine management incentive compensation and for budgeting, forecasting and planning purposes. Our management considers these non-GAAP financial measures, in addition to operating income, to be important in estimating our enterprise and stockholder values and for making strategic and operating decisions. In addition, analysts, investors and creditors use these non-GAAP financial measures when analyzing our operating performance, financial condition and cash-generating ability. We use EBITDA and adjusted EBITDA as performance measures and adjusted free cash flows as a liquidity measure.

We do not consider non-GAAP financial measures an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non-GAAP financial measures is that they may exclude significant expense and income items that are required by GAAP to be recognized in our Financial Statements. In addition, they reflect the exercise of management’s judgment about which expense and income items are excluded or included in determining these non-GAAP financial measures. In order to compensate for these limitations, reconciliations of our non-GAAP financial measures to their most directly comparable GAAP financial measures are provided below. Non-GAAP financial measures are not necessarily indicative of results that may be generated in future periods and should not be relied upon, in whole or part, in evaluating our financial condition, results of operations or future prospects.

Table of Contents

EBITDA from continuing operations for the quarter ended September 30, 2023 decreased $45 million compared to the same prior year quarter, driven by the decrease in net sales across all segments, partially offset by lower input, logistics and maintenance costs. EBITDA from continuing operations for the nine months ended September 30, 2023 decreased $17 million compared to the same prior year period, driven by lower net sales in our Paperboard segment, higher labor costs and the impact of an extended maintenance outage in the prior year, partially offset by the increase in net sales in our High Purity Cellulose and High-Yield Pulp segments and lower input and logistics costs. See Results of Operations above for additional discussion of the changes in our operating results.

Adjusted Free Cash Flows

Adjusted free cash flows is defined as cash provided by operating activities of continuing operations adjusted for capital expenditures, net of proceeds from the sale of assets and excluding strategic capital expenditures deemed discretionary by management. Adjusted free cash flows is a non-GAAP financial measure of cash generated during a period, which is available for debt reduction, strategic capital expenditures, acquisitions and repurchases of our common stock. Adjusted free cash flows is not necessarily indicative of the adjusted free cash flows that may be generated in future periods.

Cash flows of operating activities of continuing operations is reconciled to adjusted free cash flows as follows:


	Nine Months Ended
(in millions)	September 30, 2023		September 24, 2022
Cash provided by operating activities-continuing operations	$	82	$	7
Capital expenditures, net(a)	(55)		(92)
Adjusted free cash flows-continuing operations	$	27	$	(85)

(a)Net of proceeds from the sale of assets and excluding strategic capital expenditures. Strategic capital expenditures for the nine months ended September 30, 2023 and September 24, 2022 were $40 million and $22 million, respectively.

Adjusted free cash flows of continuing operations increased primarily due to changes in working capital and lower capital expenditures. See Cash Flows above for additional discussion of our operating cash flows.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market and Other Economic Risks

We are exposed to various market risks, primarily changes in interest rates, currency and commodity prices. Our objective is to minimize the economic impact of these market risks. We may use derivatives in accordance with policies and procedures approved by the Finance & Strategic Planning Committee of our Board of Directors.

Foreign Currency

We manage our foreign currency exposures by balancing certain assets and liabilities denominated in foreign currencies. We may also use foreign currency forward contracts to manage these exposures. The principal objective of such contracts is to minimize the potential volatility and financial impact of changes in foreign currency exchange rates. We do not utilize financial instruments for trading or other speculative purposes.

Prices

The prices, sales volumes and margins of the commodity products of our High Purity Cellulose segment and all the products of the High-Yield Pulp segment have historically been cyclically affected by economic and market shifts, fluctuations in capacity and changes in foreign currency exchange rates. These products have less distinguishing qualities from producer to producer and competition is based primarily on price, which is determined by market supply relative to demand. The overall levels of demand for the products we manufacture, and consequently our sales and profitability, reflect fluctuations in end user demand. Our cellulose specialties product prices are impacted by market supply and demand, raw material and processing costs, changes in global currencies and other factors.

Table of Contents

Certain key input costs, such as wood fiber, chemicals and energy, may experience significant price fluctuations, also impacted by market shifts, fluctuations in capacity and other demand and supply dynamics. We may periodically enter into commodity forward contracts to fix some of our energy costs that are subject to price volatility caused by weather, supply conditions, political and economic variables and other unpredictable factors. Such forward contracts partially mitigate the risk of changes to our gross margins resulting from an increase or decrease in these costs. Forward contracts that are derivative instruments are reported in our consolidated balance sheets at their fair values, unless they qualify for the normal purchase normal sale exception and such exception has been elected, in which case, the fair values of such contracts are not recognized in the balance sheet.

Variable Interest Rates

As of September 30, 2023, we had $251 million of variable rate debt subject to interest rate risk. In the third quarter of 2023 we issued variable rate term loan financing of $250 million, which was used with cash on hand to redeem the $318 million outstanding principal balance of our fixed rate 2024 Notes. At this borrowing level, a hypothetical one percent change in interest rates would have resulted in a $2 million annual change in interest expense. At December 31, 2022, we had $4 million of variable rate debt subject to interest rate risk, for which a hypothetical one percent change in rates would have resulted in an immaterial change in interest expense for the period.

The fair market value of our long-term fixed interest rate debt is also subject to interest rate risk when the debt becomes due or if we do not hold the debt until maturity. The estimated fair value of our fixed-rate debt at September 30, 2023 and December 31, 2022 was $440 million and $839 million, respectively, compared to its respective $517 million and $854 million principal amounts. We use quoted market prices to estimate the fair value of our fixed-rate debt. Generally, the fair market value of fixed-rate debt will increase as interest rates fall and decrease as interest rates rise.

Item 4. Controls and Procedures

Management’s Evaluation of Disclosure Controls and Procedures

Our management is responsible for establishing and maintaining adequate disclosure controls and procedures. Disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) are designed with the objective of ensuring that information required to be disclosed in reports filed under the Exchange Act, such as this Quarterly Report on Form 10-Q, is (1) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (2) accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Because of the inherent limitations in all control systems, no control evaluation can provide absolute assurance that all control exceptions and instances of fraud have been prevented or detected on a timely basis. Even systems determined to be effective can provide only reasonable assurance their objectives are achieved.

Based on an evaluation of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q, our management, including the Chief Executive Officer and Chief Financial Officer, concluded the design and operation of the disclosure controls and procedures were effective as of September 30, 2023.

Internal Control over Financial Reporting

For the quarter ended September 30, 2023, based upon the evaluation required by SEC Rule 13a-15(d), there were no changes in our internal control over financial reporting that would materially affect or are reasonably likely to materially affect our internal control over financial reporting.

Part II. Other Information

Item 1. Legal Proceedings

The Company is engaged in various legal and regulatory actions and proceedings and has been named as a defendant in various lawsuits and claims arising in the ordinary course of business. While the Company has procured reasonable and customary insurance covering risks normally occurring in connection with its businesses, the Company has, in certain cases, retained some risk through the operation of self-insurance, primarily in the areas of workers’ compensation, property insurance, business interruption and general liability. While there can be no assurance, the ultimate outcomes of these actions, either individually or in the aggregate, are not expected to have a material adverse effect on the Company’s financial position, results of operations or cash flows.

Item 1A. Risk Factors

There have been no material changes or updates to the risk factors previously disclosed in our 2022 Form 10-K.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Commitments and Contingencies	9 Months Ended
Commitments and Contingencies	Sep. 30, 2023
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	17. Commitments and Contingencies Commitments The Company had no material changes to the purchase obligations presented in its 2022 Form 10-K that were outside the normal course of business during the nine months ended September 30, 2023. The Company’s purchase obligations continue to primarily consist of commitments for the purchase of natural gas, steam energy and wood chips. The Company leases certain buildings, machinery and equipment under various operating and finance leases. See Note 5—Leases for further information. Litigation and Contingencies Duties on Canadian Softwood Lumber Sold to the U.S. The Company previously operated six softwood lumber mills in Ontario and Quebec, Canada, and exported softwood lumber into the U.S. from Canada. In connection with these exports, the Company paid approximately $112 million for softwood lumber duties between 2017 and August 28, 2021, including $1 million of ancillary fees, which were recorded as expense in the periods incurred. As part of the sale of its lumber assets, the Company retained all rights and obligations to softwood duties generated or incurred through the closing date of the sale. As of September 30, 2023, the Company had a $40 million long-term receivable associated with the USDOC’s determinations of the revised rates for the 2017, 2018, 2019, 2020 and 2021 periods. This amount does not include interest, which will be due on any amounts refunded. The Company estimates interest earned on the total amount of softwood lumber duties paid to be approximately $6 million. Cash is not expected to return to the Company until final resolution of the softwood lumber dispute, which remains subject to legal challenges. Other In addition to the above, the Company is engaged in various legal and regulatory actions and proceedings and has been named as a defendant in various lawsuits and claims arising in the ordinary course of business. While the Company has procured reasonable and customary insurance covering risks normally occurring in connection with its businesses, the Company has, in certain cases, retained some risk through the operation of self-insurance, primarily in the areas of workers’ compensation, property insurance, business interruption and general liability. These other lawsuits and claims, either individually or in the aggregate, are not expected to have a material adverse effect on the Company’s financial position, results of operations or cash flows. Guarantees and Other The Company provides financial guarantees as required by creditors, insurance programs and various governmental agencies. As of September 30, 2023, the Company had net exposure of $34 million from various standby letters of credit, primarily for financial assurance relating to environmental remediation, credit support for natural gas and electricity purchases and guarantees related to foreign retirement plan obligations. These standby letters of credit represent a contingent liability; the Company would only be liable upon its default on the related payment obligations. The standby letters of credit have various expiration dates and are expected to be renewed as required. The Company had surety bonds of $90 million as of September 30, 2023, primarily to comply with financial assurance requirements relating to environmental remediation and post closure care, to provide collateral for the Company’s workers’ compensation program and to guarantee taxes and duties for products shipped internationally. These surety bonds expire at various dates and are expected to be renewed annually as required. LTF is a venture in which the Company owns 45 percent and its partner, Borregaard ASA, owns 55 percent. The Company is a guarantor of LTF’s financing agreements and, in the event of default, expects it would only be liable for its proportional share of any repayment under the agreements. The Company’s proportion of the LTF financing agreement guarantee was $29 million at September 30, 2023. The Company has not recorded any liabilities for these financial guarantees in its consolidated balance sheets, either because the Company has recorded the underlying liability associated with the guarantee or the guarantee is dependent on the Company’s own performance and, therefore, is not subject to the measurement requirements or because the Company has calculated the estimated fair value of the guarantee and determined it to be immaterial based upon the current facts and circumstances that would trigger a payment obligation. It is not possible to determine the maximum potential amount of liability under these potential obligations due to the unique set of facts and circumstances likely to be involved with each provision. As of December 31, 2022, a collective bargaining agreement covering approximately 575 unionized employees was expired. The employees continued to work under the terms of the expired contract until negotiations concluded in the second quarter of 2023 and final agreement with the union was reached. As of September 30, 2023, all of the Company’s collective bargaining agreements covering its unionized employees were current.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The unaudited consolidated financial statements and notes thereto of the Company have been prepared in accordance with GAAP for interim financial information and in accordance with the rules and regulations of the SEC. In the opinion of management, these consolidated financial statements and notes reflect all adjustments, including all normal recurring adjustments, necessary for a fair presentation of the results of operations, financial position and cash flows for the periods presented. These statements and notes should be read in conjunction with the consolidated financial statements and supplementary data included in the Company’s 2022 Form 10-K. As a result of the sale of its lumber and newsprint assets in August 2021, the Company presents the results for those operations and any associated impacts as discontinued operations. Unless otherwise stated, information in these notes to consolidated financial statements relates to continuing operations. See Note 2—Discontinued Operations for further information on the sale.
Recent Accounting Developments	Recent Accounting Developments There have been no new or recently adopted accounting pronouncements impacting the Company’s consolidated interim financial statements.
Subsequent Events	Subsequent Events The Company recently began plans towards a realignment of its High Purity Cellulose assets to optimize production mix, including a consolidation of its commodity products production into the Temiscaming plant. The Company is currently evaluating the potential impact of this realignment on its consolidated financial statements and disclosures.
Fair Value Measurements	The Company uses the following methods and assumptions in estimating the fair value of its financial instruments: Cash and cash equivalents — Cash and cash equivalents are highly liquid investments purchased with an original or remaining maturity of three months or less at the date of purchase and the carrying amount is equal to fair market value. The Company measures its investments in money market and similar funds using level 1 inputs. Debt — The fair value of fixed rate debt is based upon quoted market prices for debt with similar terms and maturities. Variable rate debt adjusts with changes in the market rate and so carrying value approximates fair value.
