Overview

PCA is the third largest producer of containerboard products and a leading producer of uncoated freesheet paper in North America. We operate ten mills and 91 corrugated products manufacturing plants. Our containerboard mills produce linerboard and corrugating medium, which are papers primarily used in the production of corrugated products. Our corrugated products manufacturing plants produce a wide variety of corrugated packaging products, including conventional shipping containers used to protect and transport manufactured goods, multi-color boxes and displays with strong visual appeal that help to merchandise the packaged product in retail locations, and honeycomb protective packaging. In addition, we are a large producer of packaging for meat, fresh fruit and vegetables, processed food, beverages, and other industrial and consumer products. We also manufacture and sell UFS papers, including both commodity and specialty papers, which may have custom or specialized features such as colors, coatings, high brightness, and recycled content. We are headquartered in Lake Forest, Illinois and operate primarily in the United States.

On September 2, 2025, we completed the acquisition of the containerboard business of Greif, Inc. for $1.8 billion in cash. The Greif containerboard business includes two containerboard mills with approximately 800,000 tons of production capacity and eight sheet feeder and corrugated plants located across the United States. The operating results of the Greif Acquisition are included in PCA's results in the Packaging segment after the date of acquisition.

Included in this Item 7 are various non-GAAP financial measures, including earnings per diluted share excluding special items, net income excluding special items, earnings before non-operating pension (expense) income, interest, income taxes, and depreciation, amortization, and depletion ("EBITDA"), segment EBITDA, EBITDA excluding special items, and segment EBITDA excluding special items. We provide important disclosures regarding our presentation of non-GAAP financial measures and reconciliations of presented non-GAAP financial measures to the most comparable measures presented in accordance with GAAP later in this section under the caption "Non-GAAP Financial Measures."

ExecutiveSummary

Net sales were $9.0 billion for the year ended December 31, 2025 and $8.4 billion for 2024. We reported $774 million of net income, or $8.58 per diluted share, in 2025, compared to $805 million, or $8.93 per diluted share, in 2024. Net income included $114 million of expense for special items in 2025, compared to $9 million of expense for special items in 2024. Special items in both periods are described later in this section. Excluding special items, we recorded $888 million of net income, or $9.84 per diluted share, in 2025, compared to $814 million, or $9.04 per diluted share, in 2024.1The increase was driven by improvement in legacy PCA's earnings by $0.96 per share, partially offset by a loss of ($0.16) per share for the first four months of ownership of the Greif containerboard business. The results of the acquired business included approximately $44 million of depreciation and amortization expense, $28 million of additional interest expense, and maintenance expense for initial mill outages to make reliability and quality improvements. The increase in earnings of the legacy PCA business was driven primarily by higher prices and mix in our Packaging and Paper segments, and lower fiber costs, partially offset by higher operating and converting costs, lower sales and production volumes in our Packaging and Paper segments, higher annual outage expense, higher fixed and other expense, higher freight and logistic expenses, and higher interest expense. PCA ended the year with $668 million of cash and marketable debt securities and, including borrowing availability under its revolving credit facility, $1,241 million in liquidity.

Packaging segment operating income was $1,125 million in 2025, compared to $1,102 million for 2024. Packaging segment EBITDA excluding special items was $1,830 million in 2025, compared to $1,598 million in 2024.1The increase was driven primarily by higher containerboard and corrugated products prices and mix, higher volumes as a result of the Greif containerboard business, and lower fiber costs, partially offset by higher operating and converting costs, higher annual outage expense, higher fixed and other expense, and higher freight and logistic expenses. The lower increase in operating income as compared to Packaging segment EBITDA excluding special items was primarily due to higher depreciation and amortization expenses recorded in 2025.

Packaging prices and mix reflected our 2025 price increases for containerboard and corrugated products. Corrugated product shipments were up 6.3% per workday and in total throughout 2025, compared with 2024, with the addition of the acquired Greif business. Legacy corrugated product shipments were flat compared with 2024. Our containerboard production was approximately 305 BSF, and containerboard inventory weeks-of-supply at the end of 2025 was flat compared to year end 2024. For more information on our containerboard production and corrugated products shipments, refer to the table presented under the caption "Production and Shipments" in "Part I, Item 1. Business" of this Form 10-K. We notified customers of a $70 per ton price increase for linerboard and medium effective March 1, 2026.

Paper segment operating income was $130 million in 2025 and in 2024. Paper segment EBITDA excluding special items was $148 million in 2025, compared to $154 million in 2024.1The decrease was due primarily to higher operating costs and lower paper volumes, partially offset by higher prices and mix. Paper prices and mix reflected our 2025 price increase for office, printing, and converting papers.

Industry and Business Conditions

Trade publications reported North American industry-wide corrugated products shipments were down (1.8%) in 2025, compared to 2024. Reported industry containerboard production decreased (4.5%) compared to 2024, and reported industry containerboard inventories at the end of 2025 were approximately 2.8 million tons, up 1.3% compared to 2024. Reported containerboard export shipments decreased (11.4%) compared to 2024. In February 2025, index prices increased $40 per ton for linerboard and for corrugating medium.

The market for communication papers competes heavily with electronic data transmission and document storage alternatives. Increasing shifts to these alternatives have reduced usage of traditional print media and communication papers. Trade publications reported North American uncoated freesheet paper shipments decreased (9.6%) in 2025, compared to 2024. Average prices reported by a trade publication for cut size office papers were higher by $47 per ton, or 3.3%, in 2025 compared to 2024. Reported index prices increased $30 per ton for cut size office papers and for offset printing papers in February 2025 and $10 per ton in April 2025.

Outlook

Looking ahead to the first quarter of 2026, in our Packaging segment, we expect higher per-day volume in our legacy corrugated products plants over last year, reflecting improving demand, though shipment volume is seasonally slower than the fourth quarter and we experienced some disruption in shipments from weather events earlier in the quarter. We will produce less containerboard than the fourth quarter with two fewer operating days in the first quarter, a scheduled maintenance outage at our Counce, TN mill and lower production at the reconfigured Wallula, WA mill. Domestic containerboard and corrugated products prices will be higher with an improved corrugated product mix throughout the quarter and we expect to benefit slightly from our previously announced containerboard price increases beginning in March. Export volume is expected to be slightly higher and prices are expected to be flat to slightly down. In the Paper segment, we forecast slightly lower volume with two less mill operating days and prices and mix to be slightly lower. With the exception of fiber prices, we expect price inflation across most of our direct, indirect and fixed operating and converting costs. In addition, wood, energy, and chemical costs will also increase due to winter conditions negatively impacting usages and yields for these items. Our cost structure will begin to benefit from the Wallula reconfiguration late in the first quarter. Labor and benefits costs will be higher due to timing-related items that occur at the beginning of a new year for annual increases, the restart of payroll taxes, and share-based compensation expenses. Freight will be slightly higher and we expect slightly lower depreciation expense. Scheduled outage expenses will be lower and we assume a lower corporate tax rate. Considering these items, we expect first quarter earnings to be lower than the fourth quarter of 2025.

Results of Operations

Year Ended December 31, 2025 Compared with Year Ended December 31, 2024

The historical results of operations of PCA for the years ended December 31, 2025 and 2024 are set forth below (dollars in millions):

Net Sales

Net sales increased $606 million, or 7.2%, to $8,989 million in 2025, compared to $8,383 million in 2024.

Packaging.Net sales increased $603 million, or 7.8%, to $8,294 million, compared to $7,691 million in 2024, due to higher volume related to the acquired business ($338 million), higher containerboard and corrugated products prices and mix ($332 million) partially offset by lower legacy volume ($67 million). In 2025, export and domestic containerboard outside shipments decreased (7.8%) compared to 2024. Corrugated products shipments from the legacy PCA business were flat per day and in total, compared to 2024. Including the acquired business, shipments were up 6.3% per day and in total. In 2025, our domestic containerboard prices were 5.3% higher, while export prices were 6.2% higher than 2024.

Paper.Net sales decreased $9 million, or (1.5%), to $615 million, compared to $625 million in 2024. The decrease was due to lower volume ($20 million), partially offset by higher prices and mix ($11 million).

Gross Profit

Gross profit increased $107 million in 2025, compared to 2024. The increase was driven primarily by higher prices and mix in the Packaging and Paper segments, higher volumes in the Packaging segment, and lower fiber costs, partially offset by higher operating and converting costs, higher maintenance outage expense, higher fixed and other expense, higher freight expense, and lower volume in the Paper Segment. In 2025, gross profit included $70 million of special items expense related to Wallula mill restructuring, the Greif Acquisition, and corrugated facility closures. In 2024, gross profit included $3 million of special items expense related to Jackson mill conversion-related activities and corrugated facility closure and other costs.

Selling, General, and Administrative Expenses

Selling, general, and administrative expenses ("SG&A") increased $24 million in 2025 compared to 2024. The increase was primarily due to higher employee-related expenses and higher depreciation related to the newly acquired business, partially offset by lower bad debt expense.

Other Expense, Net

Other expense, net for the years ended December 31, 2025 and 2024 are set forth below (dollars in millions):

We discuss these items in more detail in Note 7, Other Expense, Net of the Condensed Notes to the Consolidated Financial Statements in "Part II, Item 8. Financial Statements" of this Form 10-K.

Income from Operations

Income from operations increased $6 million, or 0.5%, for the year ended December 31, 2025, compared to 2024. Income from operations in 2025 included $151 million of expense for special items compared to $12 million in 2024. Special items in 2025 included $128 million of expense for Wallula mill restructuring, $33 million of expense related to the Greif Acquisition and $10 million of income related to corrugated facility closures. Special items in 2024 included $10 million for Jackson mill conversion-related activities and $2 million of expense related to corrugated facility closure and other costs.

Packaging.Segment operating income increased $24 million to $1,125 million, compared to $1,102 million in 2024. The increase related primarily to higher containerboard and corrugated products prices and mix ($366 million), lower fiber costs ($59 million), and the impact of newly acquired Greif operations ($8 million), partially offset by higher operating and converting costs ($128 million), higher maintenance outage expenses ($40 million), lower legacy sales and production volumes ($39 million), higher depreciation expense ($33 million), higher fixed and other costs ($22 million), and higher freight expense ($16 million). Special items in 2025 included $128 million of expense for Wallula mill restructuring, $20 million of expense related to the Greif Acquisition and $10 million of income related to corrugated facility closures. Special items in 2024 included $4 million of expense for Jackson mill conversion-related activities and $2 million of expense for corrugated facility closure and other costs.

Paper.Segment operating income was $130 million in 2025 and in 2024. Higher operating costs ($9 million), lower sale sand production volumes ($8 million) higher fiber costs ($2 million), and higher maintenance outage expenses ($1 million), were partially offset by higher prices and mix ($11 million), lower fixed and other costs ($2 million), and lower freight expense ($1 million). Additional benefit was due to no significant special items in 2025 compared to $6 million of expense for Jackson mill conversion-related activities in 2024.

Non-Operating Pension Expense, Interest Expense, Net and Income Taxes

During 2025, non-operating pension expense increased $5 million compared to 2024. The increase in non-operating pension expense was related to unfavorable 2024 asset performance partially offset by favorable assumption changes.

Interest expense, net, during 2025 increased $38 million compared to 2024. The increase in interest expense, net was primarily due to higher interest expense in 2025 as a result of the Company's financing for the Greif Acquisition and the November 2023 debt refinancing and lower interest income as a result of lower interest rates on lower cash balances due to the Greif Acquisition.

During 2025, we recorded $254 million of income tax expense, compared to $259 million of income tax expense during 2024. The effective tax rate for 2025 and 2024 was 24.7% and 24.4%, respectively. The increase in our effective tax rate for 2025 compared to 2024 was primarily due to a lower federal research and development tax credit and lower excess tax benefits associated with employee restricted stock and performance unit vests.

On July 4, 2025, the President signed into law H.R.1, the One Big Beautiful Bill Act ("OBBBA"). For additional information regarding the impact of the OBBBA, see Note 8, Income Taxes, of the Consolidated Financial Statements included in "Part II, Item 8. Financial Statements and Supplementary Data" of this Form 10-K.

Liquidity and Capital Resources

Sources and Uses of Cash

Our primary sources of liquidity are net cash provided by operating activities and available borrowing capacity under our revolving credit facility. We ended the year with $529 million of cash and cash equivalents, $139 million of marketable debt securities, and $573 million of unused borrowing capacity under the revolving credit facility, net of letters of credit.

On July 31, 2025, the Company entered into two credit agreements (the "Commercial Credit Agreement" and the "Farm Credit Agreement," collectively, the "Credit Agreements"). The Commercial Credit Agreement includes a $500 million three-year unsecured term loan facility and a $600 million unsecured revolving credit facility. The Farm Credit Agreement includes a $500 million seven-year unsecured term loan facility. The Credit Agreements were fully drawn upon on September 2, 2025. Additionally, on August 11, 2025, we issued $500 million of 5.20% senior notes due 2035 through a registered public offering and used the net proceeds received from this issuance, together with the net proceeds from our term loan facilities and cash on hand, to finance the Greif Acquisition. For more information on the Greif Acquisition financing, see Note 11, Debt, of the Consolidated Financial Statements included in "Part II, Item 8. Financial Statements and Supplementary Data" of this Form 10-K as well as the information provided below under "-Financing Activities" for further information. For more information on the Greif Acquisition, see Note 5, Acquisitions of the Consolidated Financial Statements included in "Part II, Item 8. Financial Statements and Supplementary Data" of this Form 10-K as well as the information provided below under "-Investing Activities" for further information.

Currently, our primary uses of cash are for operations, capital expenditures, acquisitions, debt service, common stock dividends, and repurchases of common stock. We believe that net cash generated from operating activities, cash on hand, available borrowings under our revolving credit facility and available capital through access to capital markets will be adequate to meet our liquidity and capital requirements, including payments of any declared common stock dividends, for the foreseeable future. As our debt or credit facilities become due, we will need to repay, extend or replace such facilities. Our ability to do so will be subject to future economic conditions and financial, business, and other factors, many of which are beyond our control.

Below is a summary table of our cash flows, followed by a discussion of our sources and uses of cash through operating activities, investing activities, and financing activities (dollars in millions):

Operating Activities

Our operating cash flow is primarily driven by our earnings and changes in operating assets and liabilities, such as accounts receivable, inventories, accounts payable and other accrued liabilities, as well as other factors described below. Cash requirements for operating activities are subject to PCA's operating needs and the timing of collection of receivables and payments of payables and expenses.

During 2025, net cash provided by operating activities was $1,558 million, compared to $1,191 million for 2024, an increase of $367 million. Cash from operations excluding changes in cash used for operating assets and liabilities increased $211 million, primarily due to higher depreciation and higher deferred income tax liabilities in 2025 as discussed above. Cash increased by $156 million due to changes in operating assets and liabilities, primarily due to the following:

These favorable changes were partially offset by the following:

Investing Activities

We used $2,573 million for investing activities in 2025, compared to $278 million in 2024. We spent $829 million for internal capital investments during 2025, compared to $670 million during 2024. In September 2025, we completed the Greif Acquisition for a purchase price of $1,804 million, net of cash acquired.

In September 2024, we received $400 million in net proceeds from the maturity of our investments in time deposits, which were used to repay our 3.65% senior notes that were due on September 15, 2024.

The details of capital expenditures for property and equipment by segment for the years ended December 31, 2025 and 2024 are included in the table below (dollars in millions).

We expect capital investments in 2026 to be between $800 million and $870 million. These expenditures could increase or decrease as a result of a number of factors, including our financial results, strategic opportunities, future economic conditions, and our regulatory compliance requirements. We currently estimate capital expenditures to comply with environmental regulations will be about $21 million in 2026. Our estimated environmental expenditures could vary significantly depending upon the enactment of new environmental laws and regulations. For additional information, see "Environmental Matters" in this Management's Discussion and Analysis of Financial Condition and Results of Operations.

Financing Activities

In 2025, net cash provided by financing activities was $859 million, compared to $876 million of cash used for financing activities in 2024, an increase of $1,735 million. We paid $450 million in dividends on our common stock in 2025 compared to $449 million in 2024 and withheld shares to cover $24 million of employee restricted stock taxes in 2025 compared to $26 million in 2024. We repurchased and retired 0.8 million shares of the Company's common stock for $153 million in 2025. We had no share repurchases in 2024.

On July 31, 2025, the Company entered into the Commercial Credit Agreement and the Farm Credit Agreement. The Commercial Credit Agreement includes a $500 million three-year unsecured term loan facility and a $600 million unsecured revolving credit facility. The Farm Credit Agreements includes a $500 million seven-year unsecured term loan facility. The Credit Agreements were fully drawn upon on September 2, 2025. Additionally, on August 11, 2025, we issued $500 million of 5.20% senior notes due 2035 through a registered public offering and used the net proceeds received from this issuance, together with the net proceeds from our term loan facilities and cash on hand, to finance the Greif Acquisition. The net proceeds received from these financing activities were $1,494 million.

We paid $7 million of issuance costs, excluding lender fees, related to the Greif Acquisition financing, which includes $3 million for the bridge loan, $2 million for the Credit Agreements, and $2 million for the 5.20% senior notes due 2035.

On September 15, 2024, we used the net proceeds received from the November 2023 offering of the 5.70% senior notes due 2033 and cash on hand to repay our outstanding 3.65% senior notes due 2024. The repayment of the old 3.65% notes was $400 million excluding accrued interest.

See Note 11, Debt, of the Consolidated Financial Statements included in "Part II, Item 8. Financial Statements and Supplementary Data" of this Form 10-K for more information on our debt.

Commitments

Contractual Obligations

Our cash requirements greater than twelve months from contractual obligations and commitments include:

Off-Balance Sheet Arrangements

The Company does not have any off-balance sheet arrangements as of December 31, 2025.

Inflation and Other General Cost Increases

We are subject to both contractual, inflation, and other general cost increases. If we are unable to offset these cost increases by price increases, growth, and/or cost reductions in our operations, these inflation and other general cost increases could have a material adverse effect on our operating cash flows, profitability, and liquidity. We continuously seek opportunities to increase the efficiency of our mills and corrugated products facilities and make extensive capital investments to minimize the impact that inflation has on our cost structure.

In 2025, our total company costs including cost of sales (COS) and selling, general, and administrative expenses (SG&A) was $7.7 billion, and excluding non-cash costs (depreciation, depletion and amortization, pension and postretirement expense, and share-based compensation expense) was $7.0 billion. A 1% increase in COS and SG&A costs would increase costs by $77 million and cash costs by $70 million.

Certain items of product input costs have historically been subject to more cost volatility including fiber, purchased energy, and chemicals.

Energy

Our mills represent about 90% of our total purchased fuel costs. In 2025, our Packaging and Paper mills consumed about 101 million MMBTUs of fuel, including internally generated and externally purchased, to produce both steam and electricity. The following table for 2025 provides the total MMBTUs purchased externally by fuel type each quarter and the average cost per MMBTU by fuel type for the year. The cost per MMBTU includes the cost of the fuel plus our transportation and delivery costs.

In addition, the mills purchased 23.97 million CkWh (hundred kilowatt-hours) of electricity in 2025. The purchases by quarter and the average cost per CkWh were as follows:

Regulatory and Environmental Matters

Our operations are subject to compliance with the laws and regulations in the jurisdictions in which we operate, primarily in the United States. Of particular importance are laws and regulations relating to the environment and health and safety matters.

Environmental compliance requirements are a significant factor affecting our business. We employ processes in the manufacture of containerboard, paper, and pulp, which result in various discharges, emissions and waste disposal. These processes are subject to numerous federal, state, local and foreign environmental laws and regulations. We operate and expect to continue to operate, under environmental permits and similar authorizations from various governmental authorities that regulate such discharges, emissions, and waste disposal. The most significant of these laws affecting the Company are:

We believe that we are currently in material compliance with these and all applicable environmental rules and regulations. Because environmental regulations are constantly evolving, the Company has incurred, and will continue to incur, costs to maintain compliance with these and other environmental laws. The Company works diligently to anticipate and budget for the impact of applicable environmental regulations and does not currently expect that future environmental compliance obligations will materially affect its business or financial condition. For the year ended December 31, 2025, 2024, and 2023, we spent $64 million, $60 million, and $50 million, respectively, to comply with the requirements of these and other environmental laws. Additionally, we had $27 million of environmental capital expenditures in 2025, $19 million in 2024, and $14 million in 2023.

Under the CAA, EPA is required to conduct risk assessments for each source category subject to maximum achievable control technologies (MACT) to determine if additional standards are necessary to reduce residual risks from hazardous air pollutants (HAP) emissions. The national emissions standards for hazardous air pollutants (NESHAP) for Chemical Recovery Combustion Sources at pulp mills is due for residual risk and technology review (RTR). In November 2024, PCA was one of seven companies selected by EPA to respond to a questionnaire about operations and equipment to support EPA's requirement to revise existing Pulp MACT standards. As part of the questionnaire, EPA is requiring companies, including PCA, to undertake pollutant testing scheduled to begin Spring 2026. Five of PCA's mills will participate in the risk assessment.

As is the case with any industrial operation, PCA has, in the past, incurred costs associated with the remediation of soil or groundwater contamination, as required by the federal Comprehensive Environmental Response, Compensation and Liability Act, commonly known as the federal "Superfund" law, and analogous state laws. Cleanup requirements arise with respect to properties the Company currently owns or operates, former facilities and off-site facilities where the Company has disposed of hazardous substances. As part of the sale to PCA of the containerboard and corrugated products business of Pactiv Corporation in April 1999, Pactiv agreed to retain all liability for all former facilities and all sites associated with pre-closing off-site waste disposal. Pactiv also retained environmentally impaired real property in Filer City, Michigan unrelated to current mill operations. In addition, OfficeMax (now an indirect, wholly owned subsidiary of ODP) retains responsibility for certain environmental liabilities related to some of the businesses, facilities, and assets we acquired from Boise. Generally, this responsibility relates to hazardous substance releases and other environmental incidents that arose before 2004. Some of these liabilities could be significant; however, ODP may not have sufficient funds to satisfy its indemnification obligations, and in some cases, we may not be entitled to such indemnification.

Because liability for remediation costs under environmental laws is strict, meaning that liability is imposed without fault, joint and several, meaning that liability is imposed on each party without regard to contribution, and retroactive, PCA could receive notifications of cleanup liability in the future and this liability could be material. From 2006 through 2025, there were no significant environmental remediation costs at PCA's mills and corrugated plants. As of December 31, 2025, we maintained an environmental reserve of $30.9 million relating to on-site landfills and surface impoundments as well as ongoing and anticipated remedial projects. The Company believes that it is not reasonably possible that future environmental expenses above the $30.9 million accrued at December 31, 2025, will have a material impact on its financial condition, results of operations, and cash flows.

While legislation regarding the regulation of greenhouse gas emissions has been proposed at the federal level, it is uncertain whether such legislation will be passed and, if so, what the breadth and scope of such legislation will be. The result of the regulation of greenhouse gas emissions could be an increase in our future environmental compliance costs through carbon cap and trade systems, carbon or other related taxes, or additional capital expenditures to modify facilities to reduce carbon emissions, which may be material. However, climate change legislation and the resulting future energy policy could also provide us with opportunities if the use of renewable energy is encouraged. We currently self-generate the majority of our power requirements at our mills using renewable biogenic fuel such as bark, black liquor and biomass, which are derived from renewable and sustainable resources. While we believe we are well-positioned to take advantage of any renewable energy incentives, it is uncertain what the ultimate costs and opportunities of any climate change legislation will be and how our business and industry will be affected.

We are seeking to further improve our environmental impact and have voluntarily set goals to reduce our absolute Scope 1 and 2 (market-based) greenhouse gas emissions by 35% by 2030 from a 2021 baseline year and to reach net-zero carbon emissions within our own operations and our value chain by 2050. In addition, we and our industry support the American Forest & Paper Association's goal of a 50% reduction in Scope 1 and Scope 2 greenhouse gas emissions intensity by 2030 from a 2005 baseline. We have a carbon neutrality team, consisting of a cross-functional group of key operational, engineering, environmental, legal and sustainability personnel to lead our efforts. Our strategy to achieve greenhouse gas emissions reductions is premised upon the carbon neutrality of the biogenic fuels used in our operations and we believe that meaningful reductions in greenhouse gas emissions can be achieved through investment in more efficient operations utilizing carbon-neutral fuels and in emerging and advancing technologies. We regularly work to identify and implement projects that will improve our efficiency. To what extent and when we embark upon major capital projects to reduce emissions will depend in part upon technology advancements, emerging regulatory and tax policies involving greenhouse gas emissions, assessment of risks and the economic impact of investing in projects that reduce emissions. We also regularly assess the use of alternative, non-emitting energy sources at our own facilities (such as solar) and opportunities to support additive carbon-free grid power via renewable energy certificates (RECs) and power purchase agreements (PPAs), where feasible to do so, and partnering with utilities to procure carbon-free power where opportunities exist. We annually report key data to our stakeholders regarding our greenhouse gas emissions, among other things, in our responsibility report. Our responsibility report is available on our website and is not intended to be incorporated by reference herein.

We are also subject to extensive federal, state and local laws related to workplace health and safety, and our safety management system includes measures to assure compliance with these laws and regulations. We do not believe that future compliance with health and safety laws and regulations will have a material adverse effect on our financial condition, results of operations or cash flows.

Critical Accounting Policies and Estimates

Management's discussion and analysis of financial condition and results of operations are based upon the Company's consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. On an ongoing basis, PCA evaluates its estimates, including those related to business combinations, goodwill and intangible assets, pensions and other postretirement benefits, environmental liabilities, income taxes, and long-lived asset impairment, among others. PCA bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Critical accounting estimates are those that are most important to the portrayal of our financial condition and results. These estimates require management's most difficult, subjective, or complex judgments. We review the development, selection, and disclosure of our critical accounting estimates with the Audit Committee of our Board of Directors. The Company believes that of its significant accounting policies, the following involve a higher degree of judgment and/or complexity:

Business Combinations

From time to time, we may enter into material business combinations. We account for acquisitions using the acquisition method under which, upon obtaining control, we recognize each identifiable asset acquired and liability assumed at its acquisition date fair value. The determination of those fair values requires significant judgment and the use of valuation techniques when observable market inputs are unavailable. We engage third-party valuation specialists to review these critical assumptions and prepare detailed fair value analyses for material acquisitions.

We value acquired intangible assets using models such as the income approach, including the relief-from-royalty method and multi-period excess earnings method as well as other cost-based techniques. Key unobservable inputs include forecasted revenue, EBITDA margins, discount rate, royalty rate, and estimated useful lives. We value acquired property, plant and equipment using a combination of the cost and market approaches. The market approach estimates fair value by analyzing recent actual market transactions for similar assets or liabilities. The cost approach estimates fair value based on the expected cost to replace or reproduce the asset or liability and relies on assumptions regarding the occurrence and extent of any physical, functional and/or economic obsolescence. Some of the more significant estimates and assumptions inherent in these approaches are the values of asset replacement costs, comparable assets and estimated remaining economic lives of the assets.

Any excess of the purchase price over the fair values of identifiable net assets is recorded as goodwill. During the measurement period, up to one year from the acquisition date, significant provisional amounts are adjusted with a corresponding offset to goodwill.

On September 2, 2025, we completed the acquisition of Greif. For further detail, see Note 5, Acquisitions, of the Notes to Consolidated Financial Statements in "Part II, Item 8. Financial Statements and Supplementary Data" of this Form 10-K.

Pensions

The Company accounts for defined benefit pension plans in accordance with Accounting Standards Codification ("ASC") 715, Compensation - Retirement Benefits. The calculation of pension expense and pension liabilities requires decisions about a number of key assumptions that can significantly affect expense and liability amounts, including discount rates, expected return on plan assets, expected rate of compensation increases, longevity and service lives of participants, expected contributions, and other factors. The pension assumptions used to measure pension expense and liabilities are discussed in Note 13, Employee Benefit Plans and Other Postretirement Benefits, of the Notes to Consolidated Financial Statements in "Part II, Item 8. Financial Statements and Supplementary Data" of this Form 10-K.

We recognize the funded status of our pension plans on our Consolidated Balance Sheet and recognize the actuarial and experienced gains and losses and the prior service costs and credits as a component of "Accumulated Other Comprehensive Loss" in our Consolidated Statement of Changes in Stockholders' Equity. Actual results that differ from assumptions are accumulated and amortized over future periods and, therefore, generally affect recognized expense in future periods. At December 31, 2025, we had $41.8 million of actuarial losses and prior service costs, net of tax, recorded in "Accumulated other comprehensive loss" on our Consolidated Balance Sheet. Accumulated losses in excess of 10% of the greater of the projected benefit obligation or the market-related value of assets will be recognized on a straight-line basis over the average remaining service period of active employees in PCA plans (which is between five and eight years) and over the average remaining lifetime of inactive participants in the Boise plan (which is approximately 22 years), to the extent that losses are not offset by gains in subsequent years. While we believe that the assumptions used to measure our pension obligations are reasonable, differences in actual experience or changes in assumptions may materially affect our pension obligations and future expense.

We believe that the accounting estimate related to pensions is a critical accounting estimate because it is highly susceptible to change from period to period. As discussed above, the future effects of pension plans on our financial position and results of operations will depend on economic conditions, employee demographics, mortality rates, retirement rates, investment performance, and funding decisions, among other factors. The following table presents selected assumptions used and expected to be used in the measurement of pension expense in the following periods (dollars in millions):

A change of 0.25% in either direction to the discount rate or the expected rate of return on plan assets would have had the following effect on 2025 and 2026 pension expense (dollars in millions):

Non-GAAP Financial Measures

Earnings per diluted share excluding special items, net income excluding special items, EBITDA, EBITDA excluding special items, segment EBITDA, and segment EBITDA excluding special items are non-GAAP financial measures. Management excludes special items, as it believes that these items are not necessarily reflective of the ongoing operations of our business. These measures are presented because they provide a means to evaluate the performance of our segments and our Company on an ongoing basis using the same measures that are used by our management, because these measures assist in providing a meaningful comparison between periods and because these measures are frequently used by investors and other interested parties in the evaluation of companies and the performance of their segments. Any analysis of non-GAAP financial measures should be done in conjunction with results presented in accordance with GAAP. The non-GAAP measures are not intended to be substitutes for GAAP financial measures and should not be used as such. Reconciliations of the non-GAAP measures to the most comparable measure reported in accordance with GAAP are detailed below.
