NATURE OF BUSINESS AND SUMMARY

NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2023
Organization, Consolidation and Presentation of Financial Statements [Abstract]
NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Business Graphic Packaging Holding Company (“GPHC” and, together with its subsidiaries, the “Company”) is committed to providing consumer packaging that makes a world of difference. The Company, a leading sustainable consumer packaging provider, operates on a global basis, is one of the largest producers of cartons and containers for the packaging of consumer goods and paperboard-based foodservice packaging solutions in the United States (“U.S.”) and Europe, and holds leading market positions in paperboard used to produce consumer packaging solutions, including recycled, unbleached and bleached paperboard. The Company’s customers include many of the world’s most widely recognized companies and brands with prominent market positions in beverage, food, foodservice and other consumer products. The Company strives to provide innovative paperboard packaging solutions preferred by consumers. The Company delivers marketing and performance benefits to its customers through its global packaging network, its proprietary carton and packaging designs, and its commitment to quality, service, and environmental stewardship. Basis of Presentation and Principles of Consolidation The Company’s 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. The Company is a party to a Japanese joint venture, Rengo Riverwood Packaging, Ltd. in which it holds a 50% ownership interest that is accounted for using the equity method. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting periods. Actual results could differ from these estimates, and changes in these estimates are recorded when known. Estimates are used in accounting for, among other things, pension benefits, retained insurable risks, slow-moving and obsolete inventory, allowance for doubtful accounts, useful lives for depreciation and amortization, impairment testing of goodwill and long-lived assets, fair values related to acquisition accounting, fair value of derivative financial instruments, share based compensation, deferred income tax assets and potential income tax assessments, and loss contingencies. Cash and Cash Equivalents Cash and cash equivalents include bank deposits and other marketable securities that are highly liquid with maturities of three months or less. 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 and the creditworthiness of customers. Receivables are charged to the allowance when determined to be no longer collectible. The Company has entered into agreements to sell, on a revolving basis, certain trade accounts receivable to third party financial institutions. Transfers under these agreements meet the requirements to be accounted for as sales in accordance with the Transfers and Servicing topic of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (the “Codification”). The loss on sale is included in Other Expense (Income), Net in the Consolidated Statements of Operations. The following table summarizes the activity under these programs for the year ended December 31, 2023 and 2022, respectively: Year Ended December 31, In millions 2023 2022 Receivables Sold and Derecognized $ 3,696 $ 3,299 Proceeds Collected on Behalf of Financial Institutions 3,646 3,179 Net Proceeds Received from Financial Institutions 28 152 Deferred Purchase Price at December 31 (a) 1 — Pledged Receivables at December 31 150 197 (a) Included in Other Current Assets on the 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 consist principally of collection services, were $770 million and $753 million as of December 31, 2023 and 2022, 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. As of December 31, 2023 and 2022, the Company sold receivables of $1,136 million and $1,124 million, respectively, related to these arrangements. 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 supplier finance program. Amounts due to the Company’s suppliers that elected to participate in the SFP program are included in Accounts Payable on the Consolidated Balance Sheets and payments made under the SFP program are reflected in Cash Flows from Operating Activities in the Consolidated Statements of Cash Flows. The rollforward of the Company's outstanding obligations confirmed as valid under its supplier finance program for the years ended December 31, 2023 and 2022 are as follows: Year Ended December 31, In millions 2023 2022 Confirmed Obligations Outstanding at the Beginning of the Year $ 34 $ 26 Invoices Confirmed During the Year 117 127 Confirmed Invoices Paid During the Year (121) (119) Confirmed Obligations Outstanding at the End of the Year $ 30 $ 34 Non-cash additions to Property, Plant and Equipment, Net included within Accounts Payable on the Consolidated Balance Sheets were $145 million, $55 million, and $169 million as of December 31, 2023, 2022 and 2021, respectively. Concentration of Credit Risk The Company’s cash, cash equivalents, and accounts receivable are potentially subject to concentration of credit risk. Cash and cash equivalents are placed with financial institutions that management believes are of high credit quality. Accounts receivable are derived from revenue earned from customers located in the U.S. and internationally and generally do not require collateral. For the years ended December 31, 2023, 2022, and 2021, no customer accounted for more than 10% of net sales. Inventories Inventories are stated at the lower of cost and net realizable value with cost determined based on standard (which approximates actual), average or actual cost. Work in progress and finished goods inventories are valued at the cost of raw material consumed plus direct manufacturing costs (such as labor, utilities and supplies) as incurred and an applicable portion of manufacturing overhead. Inventories are stated net of an allowance for slow-moving and obsolete inventory. Property, Plant and Equipment Property, plant and equipment are recorded at cost. Betterments, renewals and extraordinary repairs that extend the life of the asset are capitalized; other repairs and maintenance charges are expensed as incurred. The Company’s cost and related accumulated depreciation applicable to assets retired or sold are removed from the accounts and the gain or loss on disposition is included in income from operations. 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 $8 million, $5 million and $14 million for the years ended December 31, 2023, 2022 and 2021, respectively. The Company assesses its long-lived assets, including certain identifiable intangibles, for impairment whenever events or circumstances indicate that the carrying value of an asset may not be recoverable. To analyze recoverability, the Company projects future cash flows, undiscounted and before interest, over the remaining life of such assets. If these projected cash flows are less than the carrying amount, an impairment would be recognized, resulting in a write-down of assets with a corresponding charge to earnings. The impairment loss is measured based upon the difference between the carrying amount and the fair value of the assets. The Company assesses the appropriateness of the useful life of its long-lived assets periodically. Depreciation and Amortization Depreciation is computed using the straight-line method based on the following estimated useful lives of the related assets: Buildings 40 years Land improvements 15 years Machinery and equipment 3 to 40 years Furniture and fixtures 10 years Automobiles, trucks and tractors 3 to 5 years Depreciation expense, including the depreciation expense of assets under finance leases, for 2023, 2022 and 2021 was $528 million, $463 million and $420 million, respectively. Intangible Assets Intangible assets with a determinable life are amortized on a straight-line or accelerated basis over their useful lives. The amortization expense for each intangible asset is recorded in the Consolidated Statements of Operations according to the nature of that asset. Goodwill is the Company’s only intangible asset not subject to amortization. The following table displays the intangible assets that continue to be subject to amortization and accumulated amortization expense as of December 31, 2023 and 2022: December 31, 2023 December 31, 2022 In millions Gross Carrying Amount Accumulated Amortization Net Carrying Amount Gross Carrying Amount Accumulated Amortization Net Carrying Amount Amortizable Intangible Assets: Customer Relationships (a) $ 1,574 $ (796) $ 778 $ 1,382 $ (706) $ 676 Non-Compete Agreements (a) 3 — 3 — — — Patents, Trademarks, Licenses, Leases and Developed Technology 157 (118) 39 152 (111) 41 Total $ 1,734 $ (914) $ 820 $ 1,534 $ (817) $ 717 (a) Please see “ Note 4 - Business Combinations ” for the intangibles acquired with the Tama Paperboard, LLC ("Tama”) and Bell Incorporated (“Bell”) acquisitions. The Company recorded amortization expense for the years ended December 31, 2023, 2022 and 2021 of $91 million, $90 million and $69 million, respectively. The Company expects amortization expense for the next five consecutive years to be approximately as follows: $89 million, $64 million, $59 million, $57 million, and $56 million. Goodwill The Company tests goodwill for impairment annually as of October 1, as well as whenever events or changes in circumstances suggest that the estimated fair value of a reporting unit may no longer exceed its carrying amount. The Company tests goodwill for impairment at the reporting unit level, which is an operating segment or a level below an operating segment, which is referred to as a component. A component of an operating segment is a reporting unit if the component constitutes a business for which discrete financial information is available and management regularly reviews the operating results of that component. Two or more components of an operating segment are aggregated and deemed a single reporting unit if the components have similar economic characteristics. Potential goodwill impairment is measured at the reporting unit level by comparing the reporting unit’s carrying amount (including goodwill), to the fair value of the reporting unit. When performing the quantitative analysis, the estimated fair value of each reporting unit is determined by utilizing a discounted cash flow analysis based on the Company’s forecasts, discounted using a weighted average cost of capital and market indicators of terminal year cash flows based upon a multiple of EBITDA. If the carrying amount of a reporting unit exceeds its estimated fair value, goodwill is considered impaired. In determining fair value, management relies on and considers a number of factors, including but not limited to, future operating results, business plans, economic projections of revenues and operating margins, forecasts including future cash flows, and market data and analysis, including market capitalization. The assumptions used are based on what a hypothetical market participant would use in estimating fair value. Fair value determinations are sensitive to changes in the factors described above. There are inherent uncertainties related to these factors and judgments in applying them to the analysis of goodwill impairment. Periodically, the Company may perform a qualitative impairment analysis of goodwill associated with each of its reporting units to determine if it is more likely than not that the carrying value of a reporting unit exceeded its fair value. However, the Company performed a quantitative impairment test as of October 1, 2023, and concluded goodwill was not impaired for any of its reporting units. The following is a rollforward of goodwill by reportable segment: In millions Paperboard Manufacturing Americas Paperboard Packaging Europe Paperboard Packaging Corporate/Other (a) Total Balance at December 31, 2021 $ 506 $ 968 $ 528 $ 13 $ 2,015 Acquisition of Businesses — 10 11 — 21 Impairment of Russian Business (b) — — (12) — (12) Foreign Currency Effects — 2 (46) (1) (45) Balance at December 31, 2022 $ 506 $ 980 $ 481 $ 12 $ 1,979 Acquisition of Businesses (c) 59 42 — — 101 Foreign Currency Effects — 6 18 (1) 23 Balance at December 31, 2023 $ 565 $ 1,028 $ 499 $ 11 $ 2,103 (a) Includes Australia operating segment. (b) Relates to the Company's divestiture of its Russian business. Please see "Note 19 - Impairment and Divestiture of Russian Business" for more information. (c) Represents goodwill related to the Tama and Bell acquisitions. Retained Insurable Risks It is the Company’s policy to self-insure or fund a portion of certain expected losses related to group health benefits and workers’ compensation claims. Provisions for expected losses are recorded based on the Company’s estimates, on an undiscounted basis, of the aggregate liabilities for known claims and estimated claims incurred but not reported. Asset Retirement Obligations Asset retirement obligations are accounted for in accordance with the provisions of the Asset Retirement and Environmental Obligations topic of the FASB Codification. A liability and asset are recorded equal to the present value of the estimated costs associated with the retirement of long-lived assets where a legal or contractual obligation exists and the liability can be reasonably estimated. The liability is accreted over time and the asset is depreciated over the remaining life of the asset. Upon settlement of the liability, the Company will recognize a gain or loss for any difference between the settlement amount and the liability recorded. Asset retirement obligations with indeterminate settlement dates are not recorded until such time that a reasonable estimate may be made. The Company's asset retirement obligations consist primarily of landfill closure and post-closure costs at certain of our paperboard manufacturing facilities. At December 31, 2023 and 2022, the Company had liabilities of $14 million and $13 million, respectively. The liabilities are primarily reflected as Other Noncurrent Liabilities on the Consolidated Balance Sheets. International Currency The functional currency of the international subsidiaries is usually the local currency for the country in which the subsidiaries own their primary assets. The translation of the applicable currencies into U.S. dollars is performed for balance sheet accounts using current exchange rates in effect at the balance sheet date and for revenue and expense accounts using an average exchange rate during the period. Any related translation adjustments are recorded directly to a separate component of Shareholders’ Equity, unless there is a sale or substantially complete liquidation of the underlying foreign investments. Gains and losses on foreign currency transactions are included in Other Expense (Income) in the Consolidated Statements of Operations, Net for the period in which the exchange rate changes. The Company pursues a currency hedging program which utilizes derivatives to reduce the impact of foreign currency exchange fluctuations on its consolidated financial results. Under this program, the Company has entered into forward exchange contracts in the normal course of business to hedge certain foreign currency denominated transactions. Realized and unrealized gains and losses on these forward contracts are included in the measurement of the basis of the related foreign currency transaction when recorded. Revenue Recognition The Company has two primary activities, manufacturing and the converting of paperboard for and into consumer packaging made from renewable resources, from which it generates revenue from contracts with customers. Revenue is disaggregated primarily by geography and type of activity as further explained in “ Note 15 - Business Segment and Geographic Area Information. ” All reportable segments and the Australia and Pacific Rim operating segments 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 years ended December 31, 2023, 2022 and 2021, the Company recognized $9,383 million, $9,410 million and $7,131 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 December 31, 2023 and 2022, contract assets were $28 million and $8 million, respectively. The Company's contract liabilities consist principally of rebates, and as of December 31, 2023 and 2022 were $60 million and $65 million, respectively. Shipping and Handling The Company includes shipping and handling costs in Cost of Sales. Research and Development Research and development costs, which relate primarily to the development and design of new packaging machines and products and are recorded as a component of Selling, General and Administrative expenses, are expensed as incurred. Expenses for the years ended December 31, 2023, 2022 and 2021 were $16 million, $14 million, and $10 million, respectively.

Leases [Abstract]
LEASES	LEASES The Company determines if a contract is or contains a lease at inception. The Company has operating and finance leases for warehouses, corporate and regional offices, and machinery and equipment. The Company enters into lease contracts ranging from one of three to seven years, many of which include options to extend in various increments. Variable lease costs consist primarily of variable warehousing costs, common area maintenance, taxes, and insurance. The Company’s leases do not have any significant residual value guarantees or restrictive covenants. As the implicit rate is not readily determinable for most of the Company’s leases agreements, the Company uses an estimated incremental borrowing rate to determine the initial present value of lease payments. These discount rates for leases are calculated using the Company's credit spread adjusted for current market factors, including fixed rate swaps, EURIBOR, and foreign currency rates. The components of lease costs are as follows: Year Ended December 31, In millions 2023 2022 Finance lease costs: Amortization of right-of-use asset $ 14 $ 11 Interest on lease liabilities 9 8 Operating lease costs 86 82 Short-term lease costs 29 21 Variable lease costs 14 16 Total lease costs, net $ 152 $ 138 Supplemental cash flow information related to leases was as follows: Year Ended December 31, In millions 2023 2022 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 84 $ 83 Operating cash flows from finance leases 9 8 Financing cash flows from finance leases 9 9 Right-of-use assets obtained in exchange for lease obligations: Operating leases 70 52 Finance leases — 42 Supplemental balance sheet information related to leases was as follows: December 31, In millions, except lease term and discount rate Balance Sheet Classification 2023 2022 Operating Leases: Operating lease right-of-use asset Other Assets $ 228 $ 245 Current operating lease liabilities Other Accrued Liabilities $ 62 $ 66 Noncurrent operating lease liabilities Other Noncurrent Liabilities 189 184 Total operating lease liabilities $ 251 $ 250 Finance Leases: Property, Plant and Equipment $ 197 $ 197 Accumulated depreciation (52) (38) Property, Plant and Equipment, net $ 145 $ 159 Current finance lease liabilities Short-Term Debt and Current Portion of Long-Term Debt $ 7 $ 11 Noncurrent finance lease liabilities Long-Term Debt 154 159 Total finance lease liabilities $ 161 $ 170 Weighted Average Remaining Lease Term (Years): Operating leases 6 7 Finance leases 16 16 Weighted Average Discount Rate: Operating leases 4.10 % 3.76 % Finance leases 5.17 % 5.31 % Maturities of lease liabilities are as follows: In millions Year ending December 31, Operating Leases Finance Leases 2024 $ 69 $ 16 2025 56 15 2026 43 14 2027 34 15 2028 21 16 Thereafter 59 165 Total lease payments $ 282 $ 241 Less imputed interest (31) (80) Total $ 251 $ 161

STOCK INCENTIVE PLANS

STOCK INCENTIVE PLANS	12 Months Ended

Share-Based Payment Arrangement [Abstract]
STOCK INCENTIVE PLANS	STOCK INCENTIVE PLANS The Company has one active equity compensation plan from which new grants may be made, the Graphic Packaging Holding Company 2014 Omnibus Stock and Incentive Compensation Plan (the “2014 Plan”). The 2014 Plan allows for granting shares of stock, options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), restricted stock awards (“RSAs”), and other types of stock-based and cash awards. Awards under the 2014 Plan vest and expire in accordance with terms established at the time of grant. Shares issued pursuant to awards under the 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 December 31, 2023, there were 8.9 million shares remaining available to be granted under the 2014 Plan. Stock Awards, Restricted Stock and Restricted Stock Units Under the 2014 Plan and related RSU grant agreements, RSUs granted to employees generally vest and become payable in three years from the date of grant. RSUs granted to employees generally contain some combination of service and performance objectives based on various financial targets and relative total shareholder return that must be met for the RSUs to vest. 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 years ended December 31 is as follows: 2023 2022 2021 RSUs — Employees and Non-Employee Directors 1,780,345 1,943,769 1,680,997 Weighted-average grant date fair value $ 23.74 $ 20.19 $ 16.14 Stock Awards — Board of Directors 25,588 34,160 55,055 Weighted-average grant date fair value $ 25.01 $ 20.49 $ 17.80 A summary of the changes in the number of unvested RSUs from December 31, 2020 to December 31, 2023 is presented below: RSUs Weighted Average Grant Date Fair Value Outstanding — December 31, 2020 5,141,706 $ 14.02 Granted (a) 1,680,997 16.14 Released (2,121,203) 14.88 Forfeited (359,100) 14.39 Performance adjustment (b) 587,461 15.09 Outstanding — December 31, 2021 4,929,861 $ 14.47 Granted (a) 1,943,769 20.19 Released (2,180,435) 12.34 Forfeited (193,145) 17.59 Performance adjustment (b) 324,814 12.52 Outstanding — December 31, 2022 4,824,864 $ 17.48 Granted (a) 1,780,345 23.74 Released (2,313,891) 15.62 Forfeited (102,583) 20.21 Performance adjustment (b) 753,702 15.59 Outstanding — December 31, 2023 4,942,437 $ 20.20 (a) Grant activity for all performance-based RSUs is disclosed at target. (b) Reflects the number of RSUs paid out above target levels based on actual performance measured at the end of the performance period. The initial value of the service-based RSUs is generally based on the closing market value of GPHC’s common stock on the date of grant, discounted to reflect that the RSUs do not accrue dividends during the vesting period. The 2023 performance-based RSU grants were valued using a Monte Carlo simulation as the total shareholder return contains a market condition. RSUs are recorded in Shareholders' Equity. The unrecognized expense at December 31, 2023 is approximately $49 million and is expected to be recognized over a weighted average period of 2 years. The value of stock awards granted to the Company's directors as compensation are based on the market value of GPHC’s common stock on the date of grant. These awards are unrestricted on the date of grant. During 2023, 2022, and 2021, $44 million, $34 million and $27 million, respectively, were charged to compensation expense for stock incentive plans and such amounts are included in Selling, General and Administrative expenses in the Consolidated Statements of Operations. During 2023, 2022, and 2021, RSUs with an aggregate fair value of $54 million, $44 million and $35 million, respectively, vested and were paid out. The RSUs vested and paid out in 2023 were granted primarily during 2020.

Retirement Benefits [Abstract]
PENSIONS AND OTHER POSTRETIREMENT BENEFITS	PENSIONS AND OTHER POSTRETIREMENT BENEFITS DEFINED BENEFIT PLANS 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 and Postretirement Expense The pension and postretirement expenses related to the Company’s plans consisted of the following: Pension Benefits Postretirement Benefits Year Ended December 31, In millions 2023 2022 2021 2023 2022 2021 Components of Net Periodic Cost: Service Cost $ 9 $ 14 $ 15 $ — $ — $ — Interest Cost 22 12 10 2 1 1 Expected Return on Plan Assets (23) (21) (19) — — — Amortization of Actuarial Loss (Gain) 5 3 5 (3) (2) (2) Net Periodic Cost (Benefit) $ 13 $ 8 $ 11 $ (1) $ (1) $ (1) Certain assumptions used in determining the pension and postretirement expenses were as follows: Pension Benefits Postretirement Benefits Year Ended December 31, 2023 2022 2021 2023 2022 2021 Weighted Average Assumptions: Discount Rate 4.86 % 2.46 % 2.11 % 5.12 % 2.92 % 2.52 % Rate of Increase in Future Compensation Levels 3.16 % 1.80 % 3.62 % — — — Expected Long-Term Rate of Return on Plan Assets 5.59 % 3.86 % 3.59 % — — — Initial Health Care Cost Trend Rate — — — 7.25 % 6.15 % 6.40 % Ultimate Health Care Cost Trend Rate — — — 4.50 % 4.50 % 4.50 % Ultimate Year — — — 2032 2031 2028 Funded Status The following table sets forth the funded status of the Company’s pension and postretirement plans as of December 31: Pension Benefits Postretirement Benefits In millions 2023 2022 2023 2022 Change in Benefit Obligation: Benefit Obligation at Beginning of Year $ 471 $ 627 $ 26 $ 33 Service Cost 9 14 — — Interest Cost 22 12 2 1 Net Actuarial Loss (Gain) 10 (152) — (7) Foreign Currency Exchange 10 (27) — — Benefits Paid (28) (24) (2) (1) Acquisition — 12 — — Other — 9 — — Benefit Obligation at End of Year $ 494 $ 471 $ 26 $ 26 Change in Plan Assets: Fair Value of Plan Assets at Beginning of Year $ 397 $ 557 $ — $ — Actual Return on Plan Assets 34 (149) — — Employer Contributions 14 24 2 1 Foreign Currency Exchange 10 (27) — — Benefits Paid (28) (24) (2) (1) Acquisition — 7 — — Other — 9 — — Fair Value of Plan Assets at End of Year $ 427 $ 397 $ — $ — Plan Assets Less than Projected Benefit Obligation $ (67) $ (74) $ (26) $ (26) Amounts Recognized on the Consolidated Balance Sheets Consist of: Pension Assets $ 18 $ 19 $ — $ — Accrued Pension and Postretirement Benefits Liability — Current $ (4) $ (5) $ (3) $ (3) Accrued Pension and Postretirement Benefits Liability — Noncurrent $ (81) $ (88) $ (23) $ (23) Accumulated Other Comprehensive Income: Net Actuarial Loss (Gain) $ 83 $ 82 $ — $ (1) Prior Service Cost (Credit) $ 4 $ 3 $ (19) $ (21) Weighted Average Calculations: Discount Rate 4.69 % 4.86 % 4.96 % 5.12 % Rates of Increase in Future Compensation Levels 2.90 % 3.16 % — — Initial Health Care Cost Trend Rate — — 8.50 % 7.25 % Ultimate Health Care Cost Trend Rate — — 4.45 % 4.50 % Ultimate Year — — 2033 2032 The Company determined pension expense using both the fair value of assets and a calculated value that averages gains and losses over a period of years. Investment gains or losses represent the difference between the expected and actual return on assets. As of December 31, 2023, the net actuarial loss in accumulated other comprehensive loss was $83 million. These net losses may increase future pension expense if not offset by (i) actual investment returns that exceed the assumed investment returns, or (ii) other factors, including reduced pension liabilities arising from higher discount rates used to calculate pension obligations, or (iii) other actuarial gains, including whether such accumulated actuarial losses at each measurement date exceed the “corridor” determined under the Compensation — Retirement Benefits topic of the FASB Codification. For the largest plan, the actuarial loss is amortized over the average remaining service period of employees expected to receive benefits. The discount rate used to determine the present value of future pension obligations at December 31, 2023 was based on a yield curve constructed from a portfolio of high-quality corporate debt securities with maturities ranging from 1 year to 30 years. Each year’s expected future benefit payments were discounted to their present value at the spot yield curve rate thereby generating the overall discount rate for the Company’s pension obligations. The weighted average discount rate used to determine the pension obligations was 4.69% and 4.86% in 2023 and 2022, respectively. The pension net actuarial loss of $10 million was primarily due to changes in the discount rate. The weighted average discount rate at December 31, 2023 was 4.69% compared to 4.86% at December 31, 2022. Accumulated Benefit Obligation The accumulated benefit obligation, (“ABO”), for all defined benefit pension plans was $491 million and $465 million at December 31, 2023 and 2022, respectively. The projected benefit obligation (“PBO”) and fair value of plan assets where the PBO exceeded plan assets were $323 million and $311 million at December 31, 2023 and 2022, respectively. The ABO and fair value of plan assets where the ABO exceeded plan assets were $319 million and $304 million at December 31, 2023 and 2022, respectively. Employer Contributions The Company made $15 million and $24 million of contributions to its pension plans during 2023 and 2022, respectively. During 2022, the Company made a $6 million contribution to the remaining U.S. defined benefit plan by effectively utilizing the excess balance related to the U.S. defined benefit plan terminated in 2020. The Company expects to make contributions in the range of $10 million to $20 million in 2024. The Company also made postretirement health care benefit payments of $2 million and $1 million during 2023 and 2022, respectively. For 2024, the Company expects to make approximately $2 million of contributions to its postretirement health care plans. Pension Assets The Company’s overall investment strategy is to achieve a mix of investments for long-term growth and near-term benefit payments through diversification of asset types, fund strategies and fund managers. Investment risk is measured on an on-going basis through annual liability measurements, periodic asset/liability studies, and quarterly investment portfolio reviews. The plans invest in the following major asset categories: cash, equity securities, fixed income securities, real estate and diversified growth funds. At December 31, 2023 and 2022, pension investments did not include any direct investments in the Company’s stock or the Company’s debt. The Company implemented a de-risking or liability driven investment strategy for its North America. and U.K. pension plans. This strategy moved assets from return seeking (equities) to investments that mirror the underlying benefit obligations (fixed income). The weighted average allocation of plan assets and the target allocation by asset category is as follows: Target 2023 2022 Cash 4 % 2 % 4 % Equity Securities 17 25 26 Fixed Income Securities 78 65 45 Other Investments 1 8 25 Total 100 % 100 % 100 % The plans’ investment in equity securities primarily includes investments in U.S. and international companies of varying sizes and industries. The strategy of these investments is to 1) exceed the return of an appropriate benchmark for such equity classes and 2) through diversification, reduce volatility while enhancing long term real growth. The plans’ investment in fixed income securities includes government bonds, investment grade bonds and non-investment grade bonds across a broad and diverse issuer base. The strategy of these investments is to provide income and stability and to diversify the fixed income exposure of the plan assets, thereby reducing volatility. The Company’s approach to developing the expected long-term rate of return on pension plan assets is based on fair values and combines an analysis of historical investment performance by asset class, the Company’s investment guidelines and current and expected economic fundamentals. The following tables set forth, by category and within the fair value hierarchy, the fair value of the Company’s pension assets at December 31, 2023 and 2022: Fair Value Measurements at December 31, 2023 In millions Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Net Asset Value at December 31, 2023(b) Asset Category: Cash $ 7 $ 2 $ 2 $ — $ 3 Equity Securities: Domestic 101 3 1 — 97 Foreign 6 6 — — — Fixed Income Securities 281 21 259 1 — Other Investments: Diversified growth fund (a) 23 — 15 8 — Insurance Contracts 9 — — 9 — Total $ 427 $ 32 $ 277 $ 18 $ 100 Fair Value Measurements at December 31, 2022 In millions Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Net Asset Value at December 31, 2022 (b) Asset Category: Cash $ 15 $ 10 $ 2 $ — $ 3 Equity Securities: Domestic 94 5 1 — 88 Foreign 7 7 — — — Fixed Income Securities 180 15 165 — — Other Investments: Real estate 4 — 4 — — Liability Driven Investment 56 35 21 — — Diversified growth fund (a) 32 — 8 24 — Insurance Contracts 9 — — 9 — Total $ 397 $ 72 $ 201 $ 33 $ 91 (a) The fund invests in a combination of traditional investments (equities, bonds, and foreign exchange), seeking to achieve returns through active asset allocation over a three (b) Investments that are measured at net asset value (or its equivalent) as a practical expedient have not been classified in the fair value hierarchy.

Estimated liabilities have been established related to the partial or complete withdrawal from certain multi-employment benefit plans for facilities that have been closed. At December 31, 2023 and December 31, 2022, the Company has withdrawal liabilities of $17 million and $18 million, respectively, related to these plans, which is recorded as Compensation and Employee Benefits and Other Noncurrent Liabilities on the Consolidated Balance Sheets, which represents the Company's best estimate of the expected withdrawal liability.

The Company also recognized income tax expense of $7 million related to unrealized foreign currency activity for intercompany loans where the entity’s functional currency and the loan denomination are different than the tax reporting currency (primarily in Sweden). During 2022, tax expense differs from the amount at the statutory rate by $20 million due to impairment charges from the planned sale of the Company's Russian business that resulted in no corresponding tax benefit and due to the recording of $10 million of tax expense to release the tax expense remaining in Other Comprehensive Income after the settlement of certain swaps. The Company also recognized tax benefits of approximately $22 million related to deferred tax assets and liabilities recognized on unrealized foreign currency activity for intercompany loans where the entity’s functional currency and the loan denomination currency are different than the tax reporting currency (primarily in Sweden). However, a valuation allowance of approximately $25 million was recorded during the year against deferred tax assets in Sweden, including the deferred tax asset related to the unrealized foreign currency activity. Additionally, the Company recorded a tax benefit of approximately $5 million related to the release of a valuation allowance recorded against the net deferred tax assets of its Brazilian subsidiary based on historic earnings. As a result of the North America Consumer Packaging (“NACP”) Combination, during 2021, federal and state income taxes are not recorded with respect to consolidated domestic earnings attributable to the Company’s minority interest partner, resulting in a difference between the effective tax rate and the statutory tax rate. In addition, during 2021, the Company recognized tax expense of approximately $4 million related to the remeasurement of deferred tax assets for executive compensation as a result of IP’s exchange of its remaining shares in GPIP during the period and approximately $3 million related to the remeasurement of its net deferred tax liability for its UK subsidiaries due to the statutory tax rate increase enacted during the second quarter. The tax effects of differences that give rise to significant portions of the deferred income tax assets and deferred income tax liabilities as of December 31 were as follows: In millions 2023 2022 Deferred Income Tax Assets: Compensation Based Accruals $ 34 $ 37 Net Operating Loss Carryforwards 74 103 Postretirement Benefits 24 26 Tax Credits 8 26 Capitalized Research & Development Costs 64 44 Unrealized Foreign Exchange — 28 Other 89 81 Valuation Allowance (37) (57) Total Deferred Income Tax Assets $ 256 $ 288 Deferred Income Tax Liabilities: Property, Plant and Equipment (672) (661) Goodwill & Other Intangibles (263) (280) Other (3) — Net Noncurrent Deferred Income Tax Liabilities $ (938) $ (941) Net Deferred Income Tax Liability $ (682) $ (653) The Company has evaluated the need to maintain a valuation allowance for deferred tax assets based on its assessment of whether it is more likely than not that deferred tax assets will be realized through the generation of future taxable income. Appropriate consideration was given to all available evidence, both positive and negative, in assessing the need for a valuation allowance. The Company reviewed its deferred income tax assets as of December 31, 2023 and 2022, respectively, and determined that it is more likely than not that a portion will not be realized. A valuation allowance of $37 million and $57 million as of December 31, 2023 and 2022, respectively, is maintained on the deferred income tax assets for which the Company has determined that realization is not more likely than not. Of the total valuation allowance at December 31, 2023, $10 million relates to net deferred tax assets in Sweden, $24 million relates to net deferred tax assets in various other foreign jurisdictions and $3 million relates to credit carryforwards in certain U.S. states as well as U.S. foreign tax credit carryforwards. The need for a valuation allowance is made on a jurisdiction-by-jurisdiction basis. As of December 31, 2023, the Company concluded that due to cumulative pretax losses and the lack of sufficient future taxable income of the appropriate character, realization is not more likely than not on the net deferred income tax assets related primarily to the Company’s operations in Australia as well as certain operations in Germany and Nigeria. The following table represents a summary of the valuation allowances against deferred tax assets as of and for the three years ended December 31, 2023, 2022, and 2021, respectively: In millions Additions Deductions December 31, Balance at Beginning of Period Charged to Costs and Expenses Charged to Other Accounts Credited to Costs and Expenses Credited to Other Accounts Balance at End of Period 2023 $ 57 $ 6 $ 1 $ (25) $ (2) $ 37 2022 38 29 1 (8) (3) 57 2021 34 4 4 (3) (1) 38 During 2023, the Company utilized it's remaining U.S. federal net operating loss carryforwards. The Company's U.S. state net operating loss carryforwards total $52 million and expire in various years through 2041. International net operating loss carryforward amounts total $296 million, of which substantially all have no expiration date. Tax Credit carryforwards total $8 million which expire in various years through 2042. Uncertain Tax Positions A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: In millions 2023 2022 2021 Balance at January 1, $ 26 $ 24 $ 20 Additions for Tax Positions of Current Year 2 2 1 Additions for Tax Positions of Prior Years 8 1 3 Reductions for Tax Positions of Prior Years (2) (1) — Balance at December 31, $ 34 $ 26 $ 24 At December 31, 2023, $30 million of the total gross unrecognized tax benefits, if recognized, would affect the annual effective income tax rate. As of December 31, 2023, none of the total gross unrecognized tax benefits recorded are related to indefinite lived deferred tax assets and did not have an impact on total tax expense. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits within its global operations in Income Tax Expense. The Company had an immaterial accrual for the payment of interest and penalties at December 31, 2023. The Company anticipates that an immaterial portion of the total unrecognized tax benefits at December 31, 2023 could change within the next twelve months. The Company files income tax returns in the U.S. federal jurisdiction, and various states and foreign jurisdictions and our income tax filings are regularly examined by federal, state and non-U.S. tax authorities. The Company’s 2018 U.S. federal corporate and partnership income tax filings are currently under examination by the Internal Revenue Service. With few exceptions, the Company is no longer subject to U.S. federal, state and local tax examinations for years before 2018. As of December 31, 2023, the Company has provided for deferred income taxes attributable to future foreign withholding tax expense related to the Company's equity investment in the joint venture, Rengo Riverwood Packaging, Ltd. In addition, Company provides deferred income taxes for future Canadian withholding tax to the extent of excess cash available for distribution after consideration of working capital needs and other debt settlement of its Canadian subsidiary, Graphic Packaging International Canada, ULC. The Company continues to assert that it is permanently reinvested in the cumulative earnings of its Canadian subsidiary in excess of the amount of cash that is on hand and available for distribution after consideration of working capital needs and other debt settlement. The Company determined that no deferred tax liability should be recorded related to the outside basis difference of its Canadian subsidiary as of December 31, 2023. The Company has not provided for deferred U.S. income taxes on approximately $92 million of its undistributed earnings in other international subsidiaries because of the Company’s intention to indefinitely reinvest these earnings outside the U.S. The determination of the amount of the unrecognized deferred U.S. income tax liability (primarily withholding tax in certain jurisdictions) on the unremitted earnings or any other associated outside basis difference is not practicable because of the complexities associated with the calculation. The Company has elected to recognize global intangible low-taxed income (“GILTI”) as period cost as incurred, therefore there are no deferred taxes recognized for basis differences that are expected to impact the amount of the GILTI inclusion upon reversal.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
FINANCIAL INSTRUMENTS, DERIVATIVES AND HEDGING ACTIVITIES	FINANCIAL INSTRUMENTS, DERIVATIVES AND HEDGING ACTIVITIES 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. 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 income statement expected for the hedged item. 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 will subsequently be reclassified into earnings as a component of Interest Expense, Net 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 December 31, 2023: Start End Notional Amount (In Millions) Weighted Average Interest Rate 04/03/2023 04/01/2024 $750 4.71% 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. Ineffectiveness measured in the hedging relationship is recorded in earnings in the period it occurs. During 2023 and 2022, there were no amounts of ineffectiveness. Additionally, there were no amounts excluded from the measure of effectiveness. As of December 31, 2021, the Company had interest rate swap positions with a notional value of $200 million, which matured in January 2022. As discussed in " Note 9 - Income Taxes ", a $10 million expense was recorded to release the tax expense remaining in Other Comprehensive Income after the settlement of these swaps in the first quarter of 2022. 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 and resulting gain or loss reclassified into Cost of Sales concurrently with the recognition of the commodity consumed. The Company has hedged approximately 65% of its expected natural gas usage for 2024. During 2023 and 2022, there were no amounts of ineffectiveness related to changes in the fair value of natural gas swap contracts. Additionally, there were no amounts excluded from the measure of effectiveness. 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 December 31, 2023 and 2022, multiple foreign currency forward exchange contracts existed, with maturities ranging up to three months. Those foreign currency exchange contracts outstanding at December 31, 2023 and 2022, when aggregated and measured in U.S. dollars at contractual rates at December 31, 2023 and 2022, respectively, had net notional amounts totaling $131 million and $111 million. Unrealized gains and losses resulting from these contracts are recognized in Other Expense (Income), Net and approximately offset corresponding recognized but unrealized gains and losses on the remeasurement of these accounts receivable. Deal Contingent Hedge On May 14, 2021, in connection with the AR Packaging acquisition, the Company entered into deal contingent foreign exchange forward contracts, with no upfront cash cost, to hedge €700 million of the acquisition price. These forward contracts settled October 29, 2021, immediately prior to the acquisition of AR Packaging and are accounted for as derivatives under ASC 815, Derivatives and Hedging. Realized losses of $48 million for the year ended December 31, 2021 resulting from these contracts are recognized in Business Combinations, Exit Activities and Other Special Charges, Net in the Consolidated Statements of Operations. For more information, see “ Note 1 - General Information ” of the Company's 2021 Annual Report on Form 10-K for the year ended December 31, 2021. Foreign Currency Movement Effect For the year ended December 31, 2023, 2022 and 2021 net currency exchange losses included in determining Income from Operations were $6 million, $3 million, and $3 million, respectively.

FAIR VALUE MEASUREMENT

FAIR VALUE MEASUREMENT	12 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	FAIR VALUE MEASUREMENT The Company follows the fair value guidance integrated into the Fair Value Measurements and Disclosures topic of the FASB Codification in regards to financial and nonfinancial assets and liabilities. Nonfinancial assets and nonfinancial liabilities include those measured at fair value in goodwill impairment testing, asset retirement obligations initially measured at fair value, and those assets and liabilities initially measured at fair value in a business combination. The FASB’s guidance defines fair value, establishes a framework for measuring fair value and expands the fair value disclosure requirements. The accounting guidance applies to accounting pronouncements that require or permit fair value measurements. It indicates, among other things, that a fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The guidance defines fair value based upon an exit price model, whereby fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The guidance clarifies that fair value should be based on assumptions that market participants would use, including a consideration of non-performance risk. Valuation Hierarchy The Fair Value Measurements and Disclosures topic establishes a valuation hierarchy for disclosure of the inputs used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows: Level 1 inputs — quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs — 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. Level 3 inputs — unobservable inputs based on the Company’s own assumptions used to measure assets and liabilities at fair value. An asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The Company has determined that its financial assets and financial liabilities include derivative instruments which are carried at fair value and are valued using Level 2 inputs in the fair value hierarchy. The Company uses valuation techniques based on discounted cash flow analyses, which reflects the terms of the derivatives and uses observable market-based inputs, including forward rates and uses market price quotations obtained from third party derivatives brokers, corroborated with information obtained from third party pricing service providers. Fair Value of Financial Instruments As of December 31, 2023 and 2022, there has not been any significant impact to the fair value of the Company's derivative liabilities due to its own credit risk. Similarly, there has not been any significant adverse impact to the Company's derivative assets based on evaluation of the Company's counterparties' credit risks. As of December 31, 2023 and December 31, 2022, the Company had commodity contract derivative liabilities, which were included in Other Accrued Liabilities on the Consolidated Balance Sheets, of $7 million and $12 million, respectively. The fair values of the Company’s other financial assets and liabilities at December 31, 2023 and 2022 approximately equal the carrying values reported on the 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 $5,039 million and $4,749 million, as compared to the carrying amounts of $5,217 million and $5,097 million as of December 31, 2023 and 2022, 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 Consolidated Statements of Operations for the year ended December 31, 2023 and 2022 is as follows: Amount of Loss (Gain) Recognized in Accumulated Other Comprehensive Loss Location in Statement of Operations Amount of Loss (Gain) Recognized in Statement of Operations Year Ended December 31, Year Ended December 31, In millions 2023 2022 2021 2023 2022 2021 Commodity Contracts $ 32 $ 2 $ (11) Cost of Sales $ 35 $ (12) $ (11) Foreign Currency Contracts — — (2) Other Expense (Income), Net — — 2 Interest Rate Swap Agreements (4) — — Interest Expense, Net (3) — 6 Total $ 28 $ 2 $ (13) $ 32 $ (12) $ (3) At December 31, 2023, the Company expects to reclassify $8 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 Consolidated Statements of Operations for the years ended December 31, 2023, 2022 and 2021 is as follows: In millions 2023 2022 2021 Foreign Currency Contracts Other Expense (Income), Net $ (3) $ (9) $ (5) Deal Contingent Foreign Exchange Hedge (a) Business Combinations, Exit Activities and Other Special Charges, Net $ — $ — $ 48 (a) For more information, see “Note 10 - Financial Instruments, Derivatives and Hedging Activities".

Commitments and Contingencies Disclosure [Abstract]
ENVIRONMENTAL AND LEGAL MATTERS	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.

Segment Reporting [Abstract]
BUSINESS SEGMENT AND GEOGRAPHIC AREA INFORMATION	BUSINESS SEGMENT AND GEOGRAPHIC AREA INFORMATION The Company has three reportable segments as follows: Paperboard Manufacturing , formerly referred to as the Paperboard Mills reportable segment, includes the seven North American paperboard facilities that produce recycled, unbleached and bleached paperboard, which is consumed internally to produce paperboard consumer packaging for the Americas and Europe Packaging segments. Paperboard not consumed internally is sold externally to a wide variety of paperboard packaging converters and brokers. The Paperboard Manufacturing segment's Net Sales represent the sale of paperboard only to external customers. The effect of intercompany transfers to the paperboard packaging segments has been eliminated from the Paperboard Manufacturing segment to reflect the economics of the integration of these segments. Americas Paperboard Packaging includes paperboard packaging sold primarily to consumer packaged goods (“CPG”) companies and cups, lids and food containers sold primarily to foodservice companies and quick-service restaurants (“QSR”) serving the food, beverage, and consumer product markets in the Americas. Europe Paperboard Packaging includes paperboard packaging sold primarily to CPG companies serving the food, beverage and consumer product markets, including healthcare and beauty, primarily in Europe. The Company allocates certain paperboard manufacturing and corporate costs to the reportable segments to appropriately represent the economics of these segments. The Corporate and Other caption includes the Pacific Rim and Australia operating segments and unallocated corporate and one-time costs. These segments are evaluated by the chief operating decision maker based primarily on Income from Operations as adjusted for depreciation and amortization. The accounting policies of the reportable segments are the same as those described above in “ Note 1 - Nature of Business and Summary of Significant Accounting Policies. ” The Company did not have any one customer who accounted for 10% or more of the Company's net sales during 2023, 2022 or 2021.

EXIT ACTIVITIES

EXIT ACTIVITIES	12 Months Ended

Restructuring and Related Activities [Abstract]
EXIT ACTIVITIES	EXIT ACTIVITIES On February 7, 2023, the Company announced its plan to invest approximately $1 billion in a new recycled paperboard manufacturing facility in Waco, Texas. In conjunction with this project, the Company announced the closure of three smaller recycled paperboard manufacturing facilities to manage capacity while lowering costs. The costs associated with these exit activities are included in the table below for the year ended December 31, 2023. In the second quarter of 2023, the Company announced its decision to accelerate the closure of one of these three recycled paperboard manufacturing facilities that is in Tama, Iowa and closed the facility in the second quarter of 2023. The costs associated with this closure are included in the table below for the year ended December 31, 2023. During 2023, the Company decided to close multiple packaging facilities by the end of 2023 and early 2024. Production from these facilities will be consolidated into our existing packaging network. The costs associated with these exit activities are included in the table below for the year ended December 31, 2023. During the third quarter of 2023, the Company decided to discontinue the project in Texarkana to modify an existing paperboard machine to add swing capacity between bleached and unbleached paperboard in order to focus growth investments in the strategic expansion of recycled paperboard capacity. The Company incurred charges of $16 million within the Paperboard Manufacturing reportable segment related to the write-off of assets, which were primarily engineering, consulting, and permitting costs for this project. The costs associated with this project are included in the table below for the year ended December 31, 2023. In March 2022, the Company announced its decision to close the Norwalk, Ohio packaging facility and closed the facility in September 2022. The Company incurred charges associated with this exit activity for post-employment benefits, retention bonuses and incentives, which are included in the Severance Costs and Other line item in the table below for the year ended December 31, 2022. During 2019, the Company announced its plans to invest in a new recycled paperboard machine in Kalamazoo, Michigan. At the time of the announcement, the Company expected to close two of its smaller recycled paperboard manufacturing facilities in 2022 in order to remain capacity neutral. During the third quarter of 2021, the Company decided to continue to operate one of the two original smaller recycled paperboard manufacturing facilities. In the second quarter of 2022, the Company closed the Battle Creek, Michigan recycled paperboard manufacturing facility.

Discontinued Operations and Disposal Groups [Abstract]
IMPAIRMENT AND DIVESTITURE OF RUSSIAN BUSINESS	IMPAIRMENT AND DIVESTITURE OF RUSSIAN BUSINESS In the second quarter of 2022, the Company began the process of divesting its interests in its two packaging facilities in Russia (the “Russian Operations”), which met the criteria to be considered a business, through a sale of 100% of the outstanding shares. The assets and liabilities to be disposed of in connection with this transaction met the held for sale criteria as of June 30, 2022 and each subsequent quarter end through the date of sale. During 2022 and 2023, the Company incurred $106 million of impairment losses associated with the Russian Operations including $96 million in 2022, which includes $12 million of goodwill impairment initially recognized in Q2 2022 and $10 million in 2023, all of which are included in the Business Combinations, Exit Activities, and Other Special Charges, Net line in the Consolidated Statement of Operations. On November 30, 2023, the Company completed the sale to former members of management of its Russian Operations (the "Buyer") for total consideration of $62 million, which was primarily a long-term loan to the Buyer with a maturity date in 2038 (the “Vendor Loan”). Given the current government sanctions and restrictions on movement of currency out of Russia to satisfy payments on the notes, the Company placed a valuation allowance of $48 million against the Vendor Loan receivable. The Vendor Loan, along with the other transaction agreements, grants the Buyer full power to direct the activities that most significantly impact the Russian Operations and economic rights over the Russian Operations, with no power or participating rights granted to the Company. There are, however, security rights in place to protect and facilitate the repayment of the Vendor Loan. Other rights included in the sale are contingent in nature and the Company does not believe such rights have significant value nor do they confer power to Company in evaluating which party is the primary beneficiary of this VIE. We will continue to monitor such rights and their impacts to the Company, if any, in the future. The Company has concluded that it is not the primary beneficiary of the business upon closing of the sale, and the Russian Operations were deconsolidated as of that date. The Vendor Loan, net is included in Other Assets on the Consolidated Balance Sheet. On the date of the sale, the Company recorded a final additional loss on the sale of $4 million, which is recorded in the Business Combinations, Exit Activities, and Other Special Charges, Net line in the Consolidated Statement of Operations. The operating results of the Russian Operations for the eleven months ended November 30, 2023 are included in the Company's Sales and Net Income in the Consolidated Statements of Operations. Total Net Sales and Net Income for the Russian Operations during this time were $90 million and $8 million, respectively. 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 (the “Loan Payable”). The Loan Payable will mature in 2037. The Loan Payable totaling $35 million is reflected in the Other Noncurrent Liabilities on the Consolidated Balance Sheet.

NATURE OF BUSINESS AND SUMMAR_2

NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2023
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The Company’s 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. The Company is a party to a Japanese joint venture, Rengo Riverwood Packaging, Ltd. in which it holds a 50% ownership interest that is accounted for using the equity method.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting periods. Actual results could differ from these estimates, and changes in these estimates are recorded when known. Estimates are used in accounting for, among other things, pension benefits, retained insurable risks, slow-moving and obsolete inventory, allowance for doubtful accounts, useful lives for depreciation and amortization, impairment testing of goodwill and long-lived assets, fair values related to acquisition accounting, fair value of derivative financial instruments, share based compensation, deferred income tax assets and potential income tax assessments, and loss contingencies.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include bank deposits and other marketable securities that are highly liquid with maturities of three months or less.
Accounts Receivable and Allowances	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 and the creditworthiness of customers. Receivables are charged to the allowance when determined to be no longer collectible. The Company has entered into agreements to sell, on a revolving basis, certain trade accounts receivable to third party financial institutions. Transfers under these agreements meet the requirements to be accounted for as sales in accordance with the Transfers and Servicing
Concentration of Credit Risk	Concentration of Credit Risk The Company’s cash, cash equivalents, and accounts receivable are potentially subject to concentration of credit risk. Cash and cash equivalents are placed with financial institutions that management believes are of high credit quality. Accounts receivable are derived from revenue earned from customers located in the U.S. and internationally and generally do not require collateral. For the years ended December 31, 2023, 2022, and 2021, no customer accounted for more than 10% of net sales.
Inventories	Inventories Inventories are stated at the lower of cost and net realizable value with cost determined based on standard (which approximates actual), average or actual cost. Work in progress and finished goods inventories are valued at the cost of raw material consumed plus direct manufacturing costs (such as labor, utilities and supplies) as incurred and an applicable portion of manufacturing overhead. Inventories are stated net of an allowance for slow-moving and obsolete inventory.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are recorded at cost. Betterments, renewals and extraordinary repairs that extend the life of the asset are capitalized; other repairs and maintenance charges are expensed as incurred. The Company’s cost and related accumulated depreciation applicable to assets retired or sold are removed from the accounts and the gain or loss on disposition is included in income from operations. 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 $8 million, $5 million and $14 million for the years ended December 31, 2023, 2022 and 2021, respectively. The Company assesses its long-lived assets, including certain identifiable intangibles, for impairment whenever events or circumstances indicate that the carrying value of an asset may not be recoverable. To analyze recoverability, the Company projects future cash flows, undiscounted and before interest, over the remaining life of such assets. If these projected cash flows are less than the carrying amount, an impairment would be recognized, resulting in a write-down of assets with a corresponding charge to earnings. The impairment loss is measured based upon the difference between the carrying amount and the fair value of the assets. The Company assesses the appropriateness of the useful life of its long-lived assets periodically.
Intangible Assets	Intangible Assets Intangible assets with a determinable life are amortized on a straight-line or accelerated basis over their useful lives. The amortization expense for each intangible asset is recorded in the Consolidated Statements of Operations according to the nature of that asset.
Goodwill	Goodwill The Company tests goodwill for impairment annually as of October 1, as well as whenever events or changes in circumstances suggest that the estimated fair value of a reporting unit may no longer exceed its carrying amount. The Company tests goodwill for impairment at the reporting unit level, which is an operating segment or a level below an operating segment, which is referred to as a component. A component of an operating segment is a reporting unit if the component constitutes a business for which discrete financial information is available and management regularly reviews the operating results of that component. Two or more components of an operating segment are aggregated and deemed a single reporting unit if the components have similar economic characteristics. Potential goodwill impairment is measured at the reporting unit level by comparing the reporting unit’s carrying amount (including goodwill), to the fair value of the reporting unit. When performing the quantitative analysis, the estimated fair value of each reporting unit is determined by utilizing a discounted cash flow analysis based on the Company’s forecasts, discounted using a weighted average cost of capital and market indicators of terminal year cash flows based upon a multiple of EBITDA. If the carrying amount of a reporting unit exceeds its estimated fair value, goodwill is considered impaired. In determining fair value, management relies on and considers a number of factors, including but not limited to, future operating results, business plans, economic projections of revenues and operating margins, forecasts including future cash flows, and market data and analysis, including market capitalization. The assumptions used are based on what a hypothetical market participant would use in estimating fair value. Fair value determinations are sensitive to changes in the factors described above. There are inherent uncertainties related to these factors and judgments in applying them to the analysis of goodwill impairment. Periodically, the Company may perform a qualitative impairment analysis of goodwill associated with each of its reporting units to determine if it is more likely than not that the carrying value of a reporting unit exceeded its fair value. However, the Company performed a quantitative impairment test as of October 1, 2023, and concluded goodwill was not impaired for any of its reporting units.
Retained Insurable Risks	Retained Insurable Risks It is the Company’s policy to self-insure or fund a portion of certain expected losses related to group health benefits and workers’ compensation claims. Provisions for expected losses are recorded based on the Company’s estimates, on an undiscounted basis, of the aggregate liabilities for known claims and estimated claims incurred but not reported.
Asset Retirement Obligations	Asset Retirement Obligations Asset retirement obligations are accounted for in accordance with the provisions of the Asset Retirement and Environmental Obligations
Accounts Payable and Supplier Finance Program	Accounts Payable and Supplier Finance Program
International Currency	International Currency The functional currency of the international subsidiaries is usually the local currency for the country in which the subsidiaries own their primary assets. The translation of the applicable currencies into U.S. dollars is performed for balance sheet accounts using current exchange rates in effect at the balance sheet date and for revenue and expense accounts using an average exchange rate during the period. Any related translation adjustments are recorded directly to a separate component of Shareholders’ Equity, unless there is a sale or substantially complete liquidation of the underlying foreign investments. Gains and losses on foreign currency transactions are included in Other Expense (Income) in the Consolidated Statements of Operations, Net for the period in which the exchange rate changes. The Company pursues a currency hedging program which utilizes derivatives to reduce the impact of foreign currency exchange fluctuations on its consolidated financial results. Under this program, the Company has entered into forward exchange contracts in the normal course of business to hedge certain foreign currency denominated transactions. Realized and unrealized gains and losses on these forward contracts are included in the measurement of the basis of the related foreign currency transaction when recorded.
Revenue Recognition	Revenue Recognition The Company has two primary activities, manufacturing and the converting of paperboard for and into consumer packaging made from renewable resources, from which it generates revenue from contracts with customers. Revenue is disaggregated primarily by geography and type of activity as further explained in “ Note 15 - Business Segment and Geographic Area Information. ” All reportable segments and the Australia and Pacific Rim operating segments 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. 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.
Shipping and Handling	Shipping and Handling The Company includes shipping and handling costs in Cost of Sales.
Research and Development	Research and Development
Adoption of New Accounting Standards and Accounting Standards Not Yet Adopted	Adoption of New Accounting Standards In September 2022, the FASB issued ASU 2022-04, Liabilities - Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations , which is intended to enhance the transparency of supplier finance programs and requires buyers in a supplier finance program to disclose sufficient information about the program to allow a user of the financial statements to understand the program’s nature, activity during the period, changes from period to period, and potential magnitude. The Company adopted this standard in the first quarter of fiscal 2023 and did not result in any changes in accounting principle upon transition. The adoption of this accounting standard did not have an impact on the Company’s financial position, results of operations and cash flows. In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Acquired Contract Assets and Contract Liabilities . Under the new guidance, the acquirer should determine what contract assets and/or contract liabilities it would have recorded under ASC 606 as of the acquisition date, as if the acquirer had entered into the original contract at the same date and on the same terms as the acquiree. The recognition and measurement of those contract assets and contract liabilities will likely be comparable to what the acquiree has recorded on its books under ASC 606 as of the acquisition date. The Company adopted this standard in the first quarter of fiscal 2023 with no material impact on the Company's financial position and results of operations. Accounting Standards Not Yet Adopted In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions . This ASU clarifies that contractual sale restrictions should not be considered in measuring the fair value of equity securities. This ASU is effective for fiscal years beginning after December 15, 2023, including interim periods therein, with early adoption permitted. The Company will continue evaluating the impact of this ASU on its disclosures. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures , which is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company will continue evaluating the impact of this ASU on its disclosures.
