Note 1. General Information

Nature of Business

Graphic Packaging Holding Company ("GPHC" and, together with its subsidiaries, the "Company") is committed to creating consumer packaging that makes a world of difference. The Company is a leading producer of consumer goods packaging made from renewable or recycled materials. The Company designs and manufactures sustainable packaging solutions including cartons, multipack cartons, trays, carriers, paperboard canisters, as well as cups and bowls made primarily from recycled paperboard, unbleached paperboard and bleached paperboard.

The Company serves a wide variety of consumer markets, from food and beverage, to foodservice, household products, beauty and health care. The Company produces packaging solutions at over 100 locations in over 20 countries around the world, serving customers ranging from local to multinational consumer products companies and retailers. The Company offers one of the most comprehensive ranges of packaging design, manufacturing and execution capabilities available. The Company currently manufactures most of the paperboard it consumes in the Americas and purchases the majority of the paperboard it consumes in its International Paperboard Packaging operations from third parties.

Graphic Packaging works closely with its customers to understand their needs and goals and to create new and innovative designs customized to their specific needs. The Company's approach serves to build and strengthen long-term relationships with purchasing, brand management, marketing and other key customer functions. The Company is organized to bring the full resources of its global and local innovation, design and manufacturing capabilities to all of its customers with the goal of delivering packaging solutions that are more circular, more functional and more convenient.

Basis of Presentation and Principles of Consolidation

The Company's Condensed Consolidated Financial Statements include all subsidiaries in which the Company has the ability to exercise direct or indirect control over operating and financial policies. Intercompany transactions and balances are eliminated in consolidation.

In the Company's opinion, the accompanying Condensed Consolidated Financial Statements contain all normal recurring adjustments necessary to fairly state the financial position, results of operations and cash flows for the interim periods. The Company's year-end Condensed Consolidated Balance Sheet data was derived from audited financial statements. The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with instructions to Form 10-Q and Rule 10-01 of Regulation S-X and do not include all the information required by accounting principles generally accepted in the United States of America ("U.S. GAAP") for complete financial statements. Therefore, these Condensed Consolidated Financial Statements should be read in conjunction with the Company's 2025 Annual Report on Form 10-K for the year ended December 31, 2025. In addition, the preparation of the Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from those estimates and changes in estimates are recorded when known.

Revenue Recognition

The Company manufactures and converts (prints, cuts, folds and glues) paperboard into consumer packaging made from renewable or recycled materials, from which it generates revenue from contracts with customers. Revenue is disaggregated primarily by geography as further explained in Note 9. Segment Information. All reportable segments and the Paperboard Manufacturing operating segment recognize revenue under the same method, allocate transaction price using similar methods, and have similar economic factors impacting the uncertainty of revenue and related cash flows.

Revenue is recognized on the Company's annual and multi-year supply contracts when the Company satisfies the performance obligation by transferring control over the product or service to a customer, which is generally based on shipping terms and passage of title under the point-in-time method of recognition. For the three months ended March 31, 2026 and 2025, the Company recognized $2,150 million and $2,110 million, respectively, of revenue from contracts with customers.

The transaction price allocated to each performance obligation consists of the stand-alone selling price, estimates of rebates and other sales or contract renewal incentives, and cash discounts and sales returns ("Variable Consideration") and excludes sales tax. Estimates are made for Variable Consideration based on contract terms and historical experience of actual results and are applied to the performance obligations as they are satisfied. Purchases by the Company's principal customers are manufactured and shipped with minimal lead time, therefore performance obligations are generally satisfied shortly after manufacturing and shipment. The Company uses standard payment terms that are consistent with industry practice.

The Company's contract assets consist primarily of contract renewal incentive payments to customers which are amortized over the period in which performance obligations related to the contract renewal are satisfied. As of March 31, 2026 and December 31, 2025, contract assets were $29 million and $21 million, respectively. The Company's contract liabilities consist principally of rebates, and as of March 31, 2026 and December 31, 2025 were $47 million and $59 million, respectively.

Accounts Receivable and Allowances

Accounts receivable are stated at the amount owed by the customer, net of an allowance for estimated uncollectible accounts, returns and allowances, and cash discounts. The allowance for doubtful accounts is estimated based on historical experience, current economic conditions, reasonable and supportable forecasts of future economic conditions, and the creditworthiness of customers. Receivables are charged to the allowance when determined to be no longer collectible.

The Company engages with third-party financial institutions to sell certain trade accounts receivable from customers. Transfers under these agreements meet the requirements to be accounted for as sales of receivables in accordance with the Transfers and Servicing topic of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification (the "Codification"). The receivables sold are reflected as a reduction of accounts receivable on the Condensed Consolidated Balance Sheets at the time of sale. The corresponding proceeds are reflected in Cash Flows from Operating Activities within the Condensed Consolidated Statements of Cash Flows. Receivables related to the Company's European program are sold in exchange for cash and a Beneficial Interest, therefore, a portion of the proceeds are reflected as "Beneficial Interest on Sold Receivables" and "Beneficial Interest Obtained in Exchange for Proceeds" in Cash Flows from Investing Activities within the Condensed Consolidated Statements of Cash Flows. The loss on sale for all programs is included in Other Expense, Net in the Condensed Consolidated Statements of Operations. The following table summarizes the activity under these programs for the three months ended March 31, 2026 and 2025:

(a)Included in Other Current Assets on the Condensed Consolidated Balance Sheets and represents a beneficial interest in the receivables sold to the financial institutions, which is a Level 3 fair value measure.

Receivables sold under all programs subject to continuing involvement, which consists principally of collection services, were $847 million and $814 million as of March 31, 2026 and December 31, 2025, respectively.

The Company also participates in supply chain financing arrangements offered by certain customers that qualify for sale accounting in accordance with the Transfers and Servicing topic of the FASB Codification. For the three months ended March 31, 2026 and 2025, the Company sold receivables of $271 million and $262 million, respectively, related to these arrangements.

The fees associated with the sale of receivables for all programs were $13 million and $14 million for the three months ended March 31, 2026 and 2025, respectively, and are included in Other Expense, Net in the Condensed Consolidated Statements of Operations.

Share Repurchases and Dividends

On April 30, 2025, the Board of Directors authorized an additional share repurchase program to allow the Company to repurchase up to $1.5 billion of the Company's issued and outstanding shares of common stock through open market purchases, privately negotiated transactions and Rule 10b5-1 plans (the "2025 share repurchase program"). The previous $500 million share repurchase program was authorized on July 27, 2023 (the "2023 share repurchase program"). During the three months ended March 31, 2026 and 2025, the Company did not repurchase any shares of its common stock. At March 31, 2026, the Company had $1.715 billion available for additional repurchases under the 2025 and 2023 share repurchase programs.

During the three months ended March 31, 2026, the Board of Directors declared regular quarterly dividends as follows:

Accounts Payable and Supplier Finance Program

The Company has arranged a supplier finance program ("SFP") with a financial intermediary, which provides certain suppliers the option to be paid by the financial intermediary earlier than the due date on the applicable invoice. The transactions are at the sole discretion of both the suppliers and financial institution, and GPHC is not a party to the agreements and has no economic interest in the supplier's decision to sell a receivable. The range of payment terms negotiated by the Company with its suppliers is consistent, irrespective of whether a supplier participates in the program. The agreement with the financial intermediary does not require GPHC to provide assets pledged as security or other forms of guarantees for the SFP. Amounts due to suppliers that elected to participate in the SFP are included in Accounts Payable on the Condensed Consolidated Balance Sheets, and payments made under the SFP are reflected in Cash Flows from Operating Activities in the Condensed Consolidated Statements of Cash Flows. Accounts Payable included $28 million and $27 million payable to suppliers who elected to participate in the SFP as of March 31, 2026 and December 31, 2025, respectively.

Non-cash additions to Property, Plant and Equipment, Net included within Accounts Payable on the Company's Condensed Consolidated Balance Sheets were $35 million and $79 million as of March 31, 2026 and December 31, 2025, respectively.

Business Combinations, Exit Activities and Other Special Items, Net

The following table summarizes the transactions recorded in Business Combinations, Exit Activities and Other Special Items, Net in the Condensed Consolidated Statements of Operations:

(a)Relates to the release of a reserve for German real estate transfer taxes incurred in connection with the Company's acquisition of AR Packaging Group AB in November 2021.

(b)In 2025, $4 million was credited to compensation expense for stock incentive plans due to Company performance adjustments for the 2024 grants of performance-based restricted stock units ("RSUs") previously expensed in 2024, and related to the terms of the 2024 grants (which differed from the 2023 grants) under the Graphic Packaging Holding Company 2014 Omnibus Stock and Incentive Compensation Plan (the "2014 Plan") (see Note 4. Stock Incentive Plans).

Exit Activities

During the first quarter of 2026, the Company decided to discontinue its project to build automated roll warehouses at its Kalamazoo, Michigan and Texarkana, Texas paperboard manufacturing facilities. This decision reflects a shift in operational priorities and the Company's focus on optimizing capital deployment and cost-management efforts. As a result of the cancellation of this project, the Company incurred charges of $40 million within Corporate and Other related to the write-off of assets, which were primarily equipment, site preparation and engineering costs for this project. These charges are included in the table above for the three months ended March 31, 2026. For more information, see Note 12. Exit Activities.

Also during the first quarter of 2026, the Company implemented additional cost and production optimization initiatives following its review of support functions and other expenses. These initiatives were incremental to the measures taken in the fourth quarter of 2025. The Company incurred $18 million of related charges in the first quarter of 2026, primarily for severance, in addition to the $6 million incurred in the fourth quarter of 2025. These charges are included in the table above for the three months ended March 31, 2026. For more information, see Note 12. Exit Activities.

During the three months ended March 31, 2026, the Company recognized a $13 million charge to adjust certain held for sale assets to their estimated fair value. Current Assets and Current Liabilities on the Condensed Consolidated Balance Sheets at March 31, 2026 include $19 million and $6 million, respectively, primarily related to multiple paperboard manufacturing and packaging facilities and other related assets that met the held for sale criteria as of March 31, 2026. Current Assets on the Condensed Consolidated Balance Sheets include $10 million primarily related to multiple paperboard manufacturing and packaging facilities that met the held for sale criteria as of December 31, 2025. For more information, see Note 12. Exit Activities.

In the fourth quarter of 2025, the Company commenced operations of its new recycled paperboard manufacturing facility located in Waco, Texas. From the project's announcement through completion, the Company incurred $55 million of start-up charges within Corporate and Other. No start-up charges were incurred in 2026 or after the facility became operational in the fourth quarter of 2025. For the three months ended March 31, 2025, the Company incurred $7 million of start-up charges, which is included in the table above. For more information, see Note 12. Exit Activities.

In connection with the Waco project, the Company closed its Middletown, Ohio recycled paperboard manufacturing facility in May 2025 and its East Angus, Québec recycled paperboard manufacturing facility in December 2025 to consolidate production into fewer, more efficient locations. Charges associated with these closures are included Exit Activities in the table above. For more information, see Note 12. Exit Activities.

During 2024, the Company decided to close multiple packaging facilities. Production from these facilities has been consolidated into other existing packaging facilities. The costs associated with these exit activities are included in Exit Activities in the table above. During three months ended March 31, 2026, the Company recognized a gain of $4 million on the sale of an exited property, which is also included in the table above. For more information see Note 12. Exit Activities.

Russia Vendor Loan and Loan Payable

In November 2023, the Company sold itstwo packaging facilities in Russia (the "Russian Operations") to former members of management (the "Buyer") for total consideration of $66 million, which primarily consisted of a long-term loan to the Buyer maturing in 2038 (the "Vendor Loan"). Due to ongoing sanctions and restrictions on movement of currency out of Russia to satisfy payments on the notes, the Company placed a valuation allowance of $51 million against the Vendor Loan receivable. Through March 31, 2026, the Buyer has repaid $4 million. The net carrying amount of the Vendor Loan is included in Other Assets on the Condensed Consolidated Balance Sheets.

In addition, the Company historically had an intercompany payable to the Russian Operations. As of the date of the sale, the intercompany payable was converted to an external third-party loan payable maturing in 2037 (the "Loan Payable"). The Loan Payable totaling $36 million is included in Other Noncurrent Liabilities on the Condensed Consolidated Balance Sheets.

Goodwill

The Company performed its annual goodwill impairment tests as of October 1, 2025. The Company concluded that all reporting units with goodwill have a fair value that exceeds their carrying value, and thus goodwill was not impaired. Fair value exceeded carrying value by approximately 2% for the International reporting unit and approximately 18% for the Foodservice reporting unit. No other reporting units had a fair value that exceeded carrying value by less than 20%. The International reporting unit and the Foodservice reporting unit had goodwill totaling $525 million and $84 million at March 31, 2026, respectively.

The variability of the assumptions that management uses to perform the goodwill impairment test depends on a number of conditions, including uncertainty about future events and cash flows. Accordingly, the Company's accounting estimates may materially change from period to period due to changing market factors. If the Company had used other assumptions and estimates or if different conditions occur in future periods, future operating results and cash flows could be materially impacted, and judgments and conclusions about the recoverability of goodwill could change. The assumptions used in the goodwill impairment testing process could also be adversely impacted by certain of the risks disclosed in Item 1A. Risk Factors in the Company's Annual Report on Form 10-K for the year ended December 31, 2025, and thus could result in future goodwill impairment charges. The Company continuously monitors events which could trigger an interim impairment analysis, such as changing business conditions, our financial performance and our market capitalization. The Company determined there were no triggering events requiring an interim impairment analysis during the three months ended March 31, 2026.

Adoption of New Accounting Standards

There have been no new accounting standards adopted since the filing of the Company's 2025 Annual Report on Form 10-K for the year ended December 31, 2025 that have significance, or potential significance, to the Condensed Consolidated Financial Statements.

Note 2. Inventories, Net

Inventories, Net by major class:

Note 3. Debt

Short-Term Debt and Current Portion of Long-Term Debt is comprised of the following:

Long-Term Debt is comprised of the following:

(a)Guaranteed by Graphic Packaging International Partners, LLC, a Delaware limited liability company and a wholly-owned subsidiary of the Company ("GPIP") and certain domestic subsidiaries.

(b)The year-to-date weighted-average effective interest rates for the Company's Senior Secured Revolving Credit Facilities were 5.51% and 5.84% as of March 31, 2026 and December 31, 2025, respectively.

On May 29, 2025, the Company, through its subsidiary GPIL, completed a $100 million tax-exempt green bond transaction through Mission Economic Development Corporation's Private Activity Bond Program (the "Green Bonds"). The Green Bonds are special limited obligations of Mission Economic Development Corporation (the "Issuer") payable from and secured by a pledge of payments to be made by GPIL under a loan agreement between the Issuer and GPIL. The Green Bonds mature and must be redeemed by the Company in 2030, but can be reissued under certain conditions until 2064. The Green Bonds were issued at a price of 101.904% and bear interest at an annual rate of 5.0%. The equivalent yield is 4.57%. The net proceeds of $99 million were used to fund a portion of GPIL's spend on construction of the new recycled paperboard manufacturing facility located in Waco, Texas (the "Project"). The bonds have been designated as Green Bonds because: (i) the proceeds were used to finance a solid waste disposal/recycling facility; and (ii) the Project will promote environmental sustainability through expected reductions in the intensity of greenhouse gas emissions, energy usage and water usage.

On October 31, 2025, GPIL entered into an Incremental Facility Amendment to the Fifth Amended and Restated Credit Agreement, dated June 3, 2024, which provides for a Delayed Draw Incremental Term Facility in the aggregate amount of up to $400 million pursuant to which GPIL may borrow a delayed draw incremental term loan in a single drawing during the period from and including March 15, 2026 and ending on April 15, 2026 (the "Delayed Draw Incremental Term Loan"). The Delayed Draw Incremental Term Loan will mature on June 30, 2027. The proceeds of the Delayed Draw Incremental Term Loan shall be used by GPIL to repay in full GPIL's 1.512% Senior Secured Notes due on April 15, 2026. The new term loan is collateralized by the same assets as the Company's Senior Secured Facilities on a pari passu basis. The new term loan will bear interest at a floating rate per annum, ranging from SOFR plus 1.00% to SOFR plus 1.75%, or base rate plus 0.00% to base rate plus 0.75%, determined using a pricing grid based on GPIL's consolidated total leverage ratio from time to time, and GPIL's election of SOFR or base rate as the reference rate. Prior to its funding, the Delayed Draw Incremental Term Loan is subject to a commitment/ticking fee ranging from 0.10% to 0.25% per annum based on the undrawn amount thereof.

At March 31, 2026, the Company and its U.S. and international subsidiaries had the following commitments, amounts outstanding and amounts available under revolving credit facilities:

(a)In accordance with its debt agreements, the Company's availability under its revolving credit facilities has been reduced by the amount of standby letters of credit issued of $2 million as of March 31, 2026, which expire at various dates through 2027 unless extended. The Company also had $72 million of standby letters of credit issued under a separate unsecured facility as of March 31, 2026, which do not have any impact on the Company's availability under its revolving credit facilities. The standby letters of credit are primarily related to the Company's workers' compensation programs and project development activities.

Interest Expense, Net

Interest Expense, Net was $64 million and $51 million for the three months ended March 31, 2026 and 2025, respectively. Interest is capitalized on assets under construction for one year or longer with an estimated spending of $1 million or more. The capitalized interest is recorded as part of the asset to which it relates and is amortized over the asset's estimated useful life. Capitalized interest was $2 million and $14 million for the three months ended March 31, 2026 and 2025, respectively.

Covenant Agreements

The Covenants in the Credit Agreement and the supplemental indentures governing the 1.512% Senior Notes due 2026,4.75% Senior Notes due 2027,3.50% Senior Notes due 2028,3.50% Senior Notes due 2029,2.625% Senior Notes due 2029,3.75% Senior Notes due 2030 and 6.375% Senior Notes due 2032 (the "Indentures"), limit the Company's ability to incur additional indebtedness. Additional covenants contained in the Credit Agreement and the Indentures may, among other things, restrict the ability of the Company to dispose of assets, incur guarantee obligations, prepay other indebtedness, repurchase stock, pay dividends and make other restricted payments, create liens, make equity or debt investments, make acquisitions, modify terms of the Indentures, engage in mergers or consolidations, change the business conducted by the Company and its subsidiaries, and engage in certain transactions with affiliates. Such restrictions could limit the Company's ability to respond to changing market conditions, fund its capital spending program, provide for unexpected capital investments or take advantage of business opportunities.

On February 26, 2026, the Company, GPIP, Graphic Packaging International, LLC, the primary operating subsidiary of the Company ("GPIL"), certain subsidiaries of GPIL, and Bank of America, N.A., as administrative agent for the lenders party thereto entered into Amendment No. 1 (the "Amendment") to the Fifth Amended and Restated Credit Agreement, dated June 3, 2024 (as amended by the Amendment, the "Credit Agreement"). The Amendment increases the permitted Consolidated Total Leverage Ratio from March 31, 2026 to June 30, 2027. The Amendment increases the existing maximum Consolidated Total Leverage Ratio covenant from 4.25 to 1.00 to 5.00 to 1.00 for the period ending March 31, 2026 through December 31, 2026 and to 4.75 to 1.00 for the period ending March 31, 2027, through and including June 30, 2027. The Amendment also incorporates an additional pricing tier when the Consolidated Total Leverage Ratio is greater than or equal to 4.75 to 1.00; limits share repurchases to $65 million on an annual basis; and places additional restrictions on acquisitions and investments in non-guarantor subsidiaries during the period commencing on February 26, 2026 and ending on September 30, 2027.

At March 31, 2026, the Company was in compliance with such covenant and the ratio was 4.18 to 1.00.

The Company must also comply with a minimum Consolidated Interest Expense Ratio of 3.00 to 1.00. At March 31, 2026, the Company was in compliance with such covenant and the ratio was 5.48 to 1.00.

Note 4. Stock Incentive Plans

The Company hasone active equity compensation plan from which new grants may be made, the Graphic Packaging Holding Company 2024 Omnibus Incentive Compensation Plan (the "2024 Plan"). Prior to the approval of the 2024 Plan and the expiration of the 2014 Plan, the Company made all new grants under the 2014 Plan. The 2024 Plan and 2014 Plan allow for granting shares of stock, options, stock appreciation rights, restricted stock, RSUs, restricted stock awards, and other types of stock-based and cash awards. Awards under the 2024 Plan and 2014 Plan vest and expire in accordance with terms established at the time of grant. Shares issued pursuant to awards under the 2024 Plan and 2014 Plan are from GPHC's authorized but unissued shares. Compensation costs are recognized on a straight-line basis over the requisite service period of the award and are adjusted for actual performance for performance-based awards. As of March 31, 2026, there were 7.3 million shares remaining available to be granted under the 2024 Plan.

Stock Awards, Restricted Stock and Restricted Stock Units

Under the 2024 and 2014 Plans and related RSU grant agreements, RSUs granted to employees generally vest and become payable inone tothree years from the date of grant. RSUs granted to employees generally contain some combination of service and performance objectives based on various financial targets that must be met for the RSUs to vest, and a relative total shareholder return modifier. The 2023 award agreements contain vesting provisions that allow retiring employees to vest on a daily pro-rata basis from the date of grant through their retirement date. For the grant agreements subsequent to the 2024 Plan, the vesting provisions were changed to allow retiring employees to vest in full upon an eligible retirement. This change required the Company to accelerate the recognition of the compensation expense for the grants subsequent to the 2024 Plan for active retirement-eligible employees. Retirement eligibility is dependent upon meeting certain age and/or years of service and notice requirements.

RSUs granted as deferred compensation for non-employee directors are fully vested but not payable until the distribution date elected by the director. Stock awards issued to non-employee directors as part of their compensation for service on the Board are unrestricted on the grant date.

Data concerning RSUs and Stock Awards granted in the three months ended March 31, 2026 is as follows:

Stock compensation expense included in the Condensed Consolidated Statements of Operations is as follows:

(a) Three months ended March 31, 2025 includes a credit to compensation expense for stock incentive plans due to Company performance adjustments for the 2024 grants of performance-based RSUs previously expensed in 2024, and related to the terms of the 2024 grants (which differed from the 2023 grants) under the 2014 Plan.

During the three months ended March 31, 2026 and 2025,0.8 million and 1.6 million shares, respectively, were issued. The shares issued were primarily related to RSUs granted to employees during 2023 and 2022, and equity grants to non-employee directors.

Note 5. Pensions and Other Postretirement Benefits

The Company maintains both defined benefit pension plans and postretirement health care plans that provide medical and life insurance coverage to eligible salaried and hourly retired employees in North America and their dependents. The Company maintains international defined benefit pension plans which are either noncontributory or contributory and are funded in accordance with applicable local laws. Pension or termination benefits are based primarily on years of service and the employee's compensation. Currently, the North American plans are closed to newly-hired employees.

Pension Expense

The pension expenses related to the Company's plans consisted of the following:

Employer Contributions

The Company made $2 million of contributions to its pension plans during the three months ended March 31, 2026 and 2025. The Company expects to make contributions in the range of $10 million to $15 million for the full year 2026.

The Company didnot make any postretirement health care benefit contributions during the three months ended March 31, 2026 and 2025. For the full year 2026, the Company expects to make approximately $2 million in contributions to its postretirement health care plans.

Note 6. Financial Instruments and Fair Value Measurement

The Company enters into derivative instruments for risk management purposes only, including derivatives designated as hedging instruments under the Derivatives and Hedging topic of the FASB Codification and those not designated as hedging instruments under this guidance. The Company uses interest rate swaps, natural gas swap contracts and forward exchange contracts. These derivative instruments are designated as cash flow hedges and, to the extent they are effective in offsetting the variability of the hedged cash flows, changes in the derivatives' fair value are not included in current earnings but are included in Accumulated Other Comprehensive Loss on the Condensed Consolidated Balance Sheets. These changes in fair value will subsequently be reclassified to earnings, contemporaneously with and offsetting changes in, the related hedged exposure and presented in the same line of the Condensed Consolidated Statements of Operations expected for the hedged item.

For more information regarding the Company's financial instruments and fair value measurement, see Note 10. Financial Instruments, Derivatives and Hedging Activities and Note 11. Fair Value Measurement of the Notes to Consolidated Financial Statements of the Company's 2025 Annual Report on Form 10-K.

Interest Rate Risk

The Company uses interest rate swaps to manage interest rate risks on future interest payments caused by interest rate changes on its variable rate term loan facilities. Changes in fair value are subsequently reclassified into earnings as a component of Interest Expense, Net in the Condensed Consolidated Statements of Operations as interest is incurred on amounts outstanding under the term loan facilities.

The following table summarizes the Company's current interest rate swap positions as of March 31, 2026 and December 31, 2025.

These derivative instruments are designated as cash flow hedges and, to the extent they are effective in offsetting the variability of the hedged cash flows, changes in the derivatives fair value are not included in current earnings but are included in Accumulated Other Comprehensive Loss on the Condensed Consolidated Balance Sheets. Ineffectiveness measured in the hedging relationship is recorded in earnings in the period in which it occurs. During the three months ended March 31, 2026, there wereno amounts of ineffectiveness related to changes in the fair value of interest rate swaps. Additionally, there wereno amounts excluded from the measure of effectiveness during those periods. As of March 31, 2025, the Company had no outstanding interest rate swaps.

Commodity Risk

To manage risks associated with future variability in cash flows and price risk attributable to purchases of natural gas, the Company enters into natural gas swap contracts to hedge prices for a designated percentage of its expected natural gas usage. Such contracts are designated as cash flow hedges. The contracts are carried at fair value with changes in fair value recognized in Accumulated Other Comprehensive Loss on the Condensed Consolidated Balance Sheets and the resulting gain or loss reclassified into Cost of Sales on the Condensed Consolidated Statements of Operations concurrently with the recognition of the commodity consumed. The Company has hedged approximately 60% and 10% of its expected natural gas usage for the remainder of 2026 and all of 2027, respectively.

During the three months ended March 31, 2026 and 2025, there wereno amounts of ineffectiveness related to changes in the fair value of natural gas swap contracts. Additionally, there wereno amounts excluded from the measure of effectiveness during those periods.

Foreign Currency Risk

The Company enters into forward exchange contracts to manage risks associated with foreign currency transactions and future variability of cash flows arising from those transactions that may be adversely affected by changes in exchange rates. The contracts are carried at fair value with changes in fair value recognized in Accumulated Other Comprehensive Loss on the Condensed Consolidated Balance Sheets and gains and losses related to these contracts are recognized in Other Expense, Net or Net Sales in the Condensed Consolidated Statements of Operations, when appropriate.

As of March 31, 2026, the Company had multiple forward exchange contracts outstanding with maturities through the remainder of 2026. The purchased contracts outstanding on March 31, 2026 and December 31, 2025, when aggregated and translated into U.S. dollars at the respective contractual rates, had notional amounts of $82 million and $118 million, respectively.

During the three months ended March 31, 2026, there wereno amounts reclassified to earnings in connection with forecasted transactions that were considered probable of not occurring and there wasno amount of ineffectiveness related to changes in the fair value of foreign currency forward contracts. Additionally, there wereno amounts excluded from the measure of effectiveness. As of March 31, 2025, the Company had no outstanding forward exchange contracts.

Derivatives not Designated as Hedges

The Company enters into forward exchange contracts to effectively hedge substantially all of its accounts receivables resulting from sales transactions and intercompany loans denominated in foreign currencies in order to manage risks associated with variability in cash flows that may be adversely affected by changes in exchange rates. At March 31, 2026 and December 31, 2025, multiple foreign currency forward exchange contracts existed, with maturities ranging up tofive months. Those foreign currency exchange contracts outstanding at March 31, 2026 and December 31, 2025, when aggregated and measured in U.S. dollars at contractual rates at March 31, 2026 and December 31, 2025, had net notional amounts totaling $158 million and $155 million, respectively. Unrealized gains and losses resulting from these contracts are recognized in Other Expense, Net in the Condensed Consolidated Statements of Operations and approximately offset corresponding recognized but unrealized gains and losses on the remeasurement of these accounts receivable.

Fair Value of Financial Instruments

The Company's derivative instruments are carried at fair value. The Company has determined that the inputs to the valuation of these derivative instruments are Level 2 in the fair value hierarchy. Level 2 inputs are defined as quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. The Company uses valuation techniques based on discounted cash flow analyses, which reflect the terms of the derivatives and use observable market-based inputs, including forward rates, and uses market price quotations obtained from independent derivatives brokers, corroborated with information obtained from independent pricing service providers.

(a)Derivative assets of $2 million are included in Other Current Assets as of March 31, 2026.

(b)Derivative liabilities of $6 million and $8 million are included in Other Accrued Liabilities as of March 31, 2026 and December 31, 2025, respectively.

The fair values of the Company's other financial assets and liabilities at March 31, 2026 and December 31, 2025 approximately equal the carrying values reported on the Condensed Consolidated Balance Sheets except for Long-Term Debt. The fair value of the Company's Long-Term Debt (excluding finance leases and deferred financing fees) was $5,530 million and $5,381 million as compared to the carrying amounts of $5,621 million and $5,434 million as of March 31, 2026 and December 31, 2025, respectively. The fair value of the Company's Total Debt, including the Senior Notes, is based on quoted market prices (Level 2 inputs). Level 2 valuation techniques for Long-Term Debt are based on quotations obtained from independent pricing service providers.

Effect of Derivative Instruments

The pre-tax effect of derivative instruments in cash flow hedging relationships in the Company's Condensed Consolidated Statements of Operations is as follows:

At March 31, 2026, the Company expects to reclassify $4 million of pre-tax loss in the next twelve months from Accumulated Other Comprehensive Loss to earnings, contemporaneously with, and offsetting changes in, the related hedged exposure. The actual amount that will be reclassified to future earnings may vary from this amount as a result of changes in market conditions.

The pre-tax effect of derivative instruments not designated as hedging instruments in the Company's Condensed Consolidated Statements of Operations is as follows:

Note 7. Income Taxes

During the three months ended March 31, 2026, the Company recognized Income Tax Benefits of $2 million on Loss before Income Taxes of $45 million. The effective tax rate for the three months ended March 31, 2026 is different from the statutory rate primarily due to the discrete tax impact of the charges associated with the adjustment of certain held for sale assets to their estimated fair value that results in no corresponding tax benefit. The Company also recorded discrete tax adjustments including $2 million for a tax shortfall related to RSUs that vested during the period and $2 million for the establishment of a valuation allowance against certain net deferred tax assets in the Netherlands. Additionally, the Company's effective tax rate is impacted by the mix of earnings between foreign and domestic jurisdictions, including those with and without valuation allowances.

During the three months ended March 31, 2025, the Company recognized Income Tax Expense of $43 million on Income before Income Taxes of $170 million. The effective tax rate for the three months ended March 31, 2025 is different from the statutory rate primarily due to the write-off of non-deductible book goodwill associated with the sale of the Company's Augusta, Georgia bleached paperboard manufacturing facility in May 2024; a benefit from purchased tax credits; discrete tax adjustments, including a tax benefit of $2 million related to excess tax benefits on RSUs that vested during the period; and the mix of earnings between foreign and domestic jurisdictions, including those with and without valuation allowances.

Note 8. Environmental and Legal Matters

Environmental Matters

The Company is subject to a broad range of foreign, federal, state and local environmental, health and safety laws and regulations, including those governing discharges to air, soil and water, the management, treatment and disposal of hazardous substances, solid waste and hazardous wastes, the investigation and remediation of contamination resulting from historical site operations and releases of hazardous substances, the recycling of packaging and the health and safety of employees. Compliance initiatives could result in significant costs, which could negatively impact the Company's consolidated financial position, results of operations or cash flows. Any failure to comply with environmental or health and safety laws and regulations or any permits and authorizations required thereunder could subject the Company to fines, corrective action or other sanctions.

Some of the Company's current and former facilities are the subject of environmental investigations and remediations resulting from historical operations and the release of hazardous substances or other constituents. Some current and former facilities have a history of industrial usage for which investigation and remediation obligations may be imposed in the future or for which indemnification claims may be asserted against the Company. Also, closures or sales of facilities may necessitate further investigation and may result in remediation activities at those facilities.

The Company has established reserves for those facilities or issues where a liability is probable and the costs are reasonably estimable. The Company believes that the amounts accrued for its loss contingencies, and the reasonably possible loss beyond the amounts accrued, are not material to the Company's consolidated financial position, results of operations or cash flows. The Company cannot estimate with certainty other future compliance, investigation or remediation costs. Some costs relating to historic usage that the Company considers to be reasonably possible of resulting in liability are not quantifiable at this time. The Company will continue to monitor environmental issues at each of its facilities, as well as regulatory developments, and will revise its accruals, estimates and disclosures relating to past, present and future operations, as additional information is obtained.

Legal Matters

The Company is a party to a number of lawsuits arising in the ordinary conduct of its business. Although the timing and outcome of these lawsuits cannot be predicted with certainty, the Company does not believe that disposition of these lawsuits will have a material adverse effect on the Company's consolidated financial position, results of operations or cash flows.

Note 9. Segment Information

The Company'sreportable segments are described as follows:

Americas Paperboard Packaging includes paperboard packaging sold primarily to consumer packaged goods ("CPG") companies serving the food, beverage and consumer product markets and cups, lids and food containers sold primarily to foodservice companies and quick-service restaurants in the Americas.

The Company's Chief Operating Decision Maker ("CODM"), who is responsible for allocating resources, assessing performance of the operating segments and making strategic decisions, has been identified as the Chief Executive Officer. The evaluation of operating segment performance is based primarily on Income from Operations. Each segment maintains separate financial information, and the CODM evaluates the segments' operating results on a regular basis.

The table below represents information for the Company's Reportable segments; amounts related to Corporate and Other are included for reconciliation purposes:

(a)Revenue from sales of paperboard to third parties is reported within Corporate and Other.
