Clearwater Paper Corp: Form 10-K for the period ended Dec 31, 2024

GENERAL

We are a premier manufacturer and supplier of Solid Bleached Sulfate (SBS) paperboard packaging products to independent converters in North America. We participate in a 10 million ton North American paperboard market, represented in three segments with a broad range of applications. SBS represents approximately half of the North American paperboard market with Coated Unbleached Kraft (CUK) and Coated Recycled Board (CRB) comprising the remaining portions. Our paperboard products are inherently sustainable, and we believe we are well positioned to capitalize on sustainability trends towards renewable and recyclable materials. We produce paperboard that is then converted and printed by independent converters and primarily used in folding carton and food service applications. Additionally, minor amounts of pulp are sold to outside customers. We strive to develop new products and innovative solutions to expand and diversify our paperboard portfolio. We believe that our status as an independent, non-integrated supplier is core to our value proposition.

Our manufacturing facilities and all other assets are located within the continental United States.

We believe we are one of the five largest producers of paperboard in North America with approximately 14% of the available U.S. production capacity in 2024. We also provide custom sheeting, slitting and cutting of paperboard products.

Acquisition and Divestiture

During 2024, through two transformational transactions, we repositioned Clearwater Paper Corporation to have a singular focus on the paperboard packaging industry. We may continue to pursue acquisitions in the future as a part of our overall growth strategy.

During the second quarter of 2024, we acquired a paperboard manufacturing facility and associated business, located in Augusta, Georgia from Graphic Packaging International, LLC (Augusta Acquisition). We paid $700 million plus an adjustment for wood inventory and other assets, totaling approximately $710.6 million. For more information, see Note 3, "Business Acquisition," in the Notes to the Consolidated Financial Statements included herein under "Item 8. Financial Statements and Supplementary Data."

During the fourth quarter of 2024, we sold our tissue business (formerly Consumer Products segment), which manufactured private branded tissue products, to Sofidel America Corp, a wholly owned subsidiary of Sofidel S.p.A. We received $1.06 billion in cash less adjustments for working capital, indebtedness and transaction expenses. For more information, see "Note 4 Discontinued Operations" in the Notes to the Consolidated Financial Statements included herein under "Item 8. Financial Statements and Supplementary Data." This divestiture represents a strategic shift in our operations and financial results resulting in discontinued operations accounting treatment associated with this division. All prior periods have been recast to reflect the discontinued operations.

Products

SBS paperboard is a premium paperboard grade that is most frequently used to produce folding cartons (also includes blister and carded packaging and top sheet), food service (including liquid packaging, cups and plates) and commercial printing items. SBS paperboard is used for such products because it is manufactured using virgin fiber combined with the kraft bleaching process, which results in superior cleanliness, brightness and consistency. SBS paperboard is often manufactured with a clay coating to provide superior surface printing qualities.

Folding carton is the largest portion of the SBS category of the North American paperboard industry. Within the folding carton segment, there are varying qualities of SBS paperboard, as well as competing paperboard substrates that can be substituted for SBS. We focus on the high end of the folding carton category which requires a premium print surface and includes uses such as packaging for pharmaceuticals, cosmetics and other premium retail goods. This generally provides for differentiation resulting in margins that are more attractive than less demanding folding carton applications.

Food service paperboard includes both liquid packaging and cup and plate categories. This includes rigid containers including juice, milk and wine sold in retail channels, premium ice cream, hot and cold cups used in quick service channels and paper plates. Our food service paperboard is known for its cleanliness and printability, and is engineered for superior performance.

With the exception of our capability to supply just-in-time sheeting and narrow rolls, we do not produce converted paperboard end-products, so we are not simultaneously a supplier of and a competitor to our customers.

Sales and marketing

We utilize various methods for the sale and distribution of our paperboard. The majority of our paperboard is sold to packaging converters in North America through sales managers located throughout the United States, with a smaller percentage channeled through distribution to commercial printers. We sell sheeted paperboard products directly to folding carton converters, merchants and commercial printers. Our principal methods of competing are product quality, customer service and price.

Competition

We compete with other manufacturers of paperboard, including unbleached and recycled grades, both domestically and internationally. Paperboard manufacturers also compete with plastic manufacturers as well as other primary and secondary packaging materials on the basis of product performance, price, quality and customer service.

Raw Materials

Wood fiber is our principal raw material, which consists of chips, sawdust and logs. We own (or lease) and operate wood chipping facilities which we believe bolsters our wood fiber position and provides short-term and long-term cost savings. Additionally, we procure a portion of our pulp requirements in order to meet product specifications. We purchase approximately 88,000 short tons of pulp which supplements our internal production capabilities.

In addition to wood fiber, we utilize a significant amount of chemicals in the production of pulp and paper, including caustic, polyethylene, starch, sodium chlorate, latex and specialty process paper chemicals. A portion of the chemicals used in our manufacturing processes, particularly in the pulp-making process, are petroleum-based or are impacted by petroleum prices.

Freight

Freight is a significant cost input for our business. Fuel prices, miles driven and line-haul rates impact our freight costs for delivery of raw materials to our manufacturing facilities, internal inventory transfers and delivery of our finished products to customers.

Energy

We consume substantial amounts of energy, such as electricity, hog fuel, steam and natural gas. While we produce the majority of our own energy needs by utilizing carbon neutral biomass, we also purchase a portion of our natural gas and electricity under supply contracts. Under most of these contracts, the providers have agreed to provide us with our requirements for a particular type of energy at a specific facility and have pricing mechanisms that adjust or set prices based on current market conditions.

Product Development

Our product development resources works directly with our sales and marketing personnel to understand long-term consumer and retailer trends with a goal of creating relevant new paperboard solutions. These innovative solutions seek to provide customers with differentiated packaging to meet consumer preferences. Our development efforts include, but are not limited to, light weight paperboard options that do not sacrifice print quality and strength; developing compostable food service products including innovations in biodegradable barriers and coatings; and continued investment in alternative fibers with up to 35% of post-consumer recycled content.

Seasonality

Customer buying patterns for our paperboard generally result in lower sales volumes for certain grades during the first and fourth quarters, compared to the second and third quarters of a given year.

CLIMATE CHANGE

Climate change is an important issue to the public, governmental authorities and various other stakeholders, and is a priority for our business. Our continuing efforts to incorporate climate risk and opportunity into our core business strategy and disclosure include:

• Governance - Incorporating sustainability issues, including climate-related topics, into quarterly Board meetings.
• Strategy - establishing GHG reduction targets validated by the Science Based Targets initiative (SBTi) and developing a roadmap to achieve reductions based upon transformed business.
• Risk & Opportunity - Integrating climate change related risk into our enterprise risk management (ERM) program, which provides a systematic approach to identifying and understanding risks to the company that

might arise from changes in regulation and physical or operational events.

We have voluntarily provided disclosure and established targets with respect to climate change. Satisfying these targets has increased and may continue to increase our capital and operational costs. Achievement of these targets is subject to various risks and uncertainties and there is no assurance that our actions or investments will meet investor expectations or any applicable regulatory standards regarding sustainability. Our failure to meet these climate targets could negatively impact our reputation which could adversely impact our business. Moreover, our voluntary establishment and disclosure of these targets may put us at a competitive disadvantage.

Metrics & Targets

• Committing to 2030 targets to reduce Scope 1 and Scope 2 GHG emissions by 30% and Scope 3 GHG emissions by 25%.
• Developing a new water conservation and effluent reduction target consistent with our understanding of the best available climate science.
• Expanding our recyclable, compostable or marine-degradable paperboard offerings to represent more than 10% of our total SBS cupstock manufacturing by 2030.
• Generating renewable fuel from our organic residual wood fiber to generate steam which is converted to electricity, reducing the need for external energy or fuel at our Idaho and Arkansas mills.

Additional information regarding our GHG targets and strategy are available in our 2024 Sustainability Report, which we prepared in accordance with the Global Reporting Initiative (GRI) Standards Core Option. Our sustainability reports are available on our website at www.clearwaterpaper.com/sustainability (http://www.clearwaterpaper.com/sustainability). The information contained in these sustainability reports is not incorporated by reference into this Form 10-K and should not be considered part of this or any other report that we file with or furnish to the SEC.

GOVERNMENTAL

For a discussion of the uncertainties and business risks associated with the environmental regulations, see Part I, Item 1A, "Risk Factors—Risks Related to Our Business Operations and the Markets in Which We Operate — We are subject to significant environmental regulation and compliance expenditures, which could increase our costs and subject us to liabilities" including information regarding environmental matters under Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this report, and which is incorporated herein by reference.

HUMAN CAPITAL

Our core values of Commitment, Collaboration, Communication, Courage, and Character are the foundation that define our culture and guide our operations to ensure that we protect, develop, and support our most critical stakeholders – our employees, customers, and communities. We apply these core values throughout our organization with key focus areas of safety and human capital management as discussed below.

Safety

The health and safety of our employees is our highest priority. We aspire to achieve zero significant workplace injuries and fatalities (SIFs) and to provide a safe, open, and accountable work environment for our employees. We have a dedicated Environmental, Health and Safety (EH&S) team that is tasked with promoting safe working practices, monitoring incidents, and working to reduce risks to our employees. Our EH&S team compiles and publishes regular safety results and leverages this information to implement enhanced safety procedures and training across our operations. We provide several channels for all employees to speak up, ask for guidance, and report concerns related to ethics or safety violations. We address employee concerns and take appropriate actions that uphold our core values.

Human Capital Management

Our approximately 2,200 employees are instrumental to delivering on our commitments to our customers and securing long term success for our organization. We actively work to attract and retain the best-qualified talent by offering competitive pay and benefits, including market-competitive compensation, healthcare, paid time off, parental leave, retirement benefits, tuition assistance, employee skills development and leadership development. We have deployed training and development programs across our organization to invest in the professional growth of our people.

We believe that a sustained commitment to fairly treating all of our employees makes us a stronger and more competitive organization. We are dedicated to fostering and sustaining an environment where our teammates are valued for their unique backgrounds, knowledge, skills, and experiences. We continue to execute on these goals.

As of December 31, 2024, approximately 1,395 of our employees are covered under collective bargaining agreements. Unions represent hourly employees at our manufacturing sites. For a discussion of the uncertainties and business risks associated with employee relations, see Part I, Item 1A, "Risk Factors — Risks Related to Our Business Operations and the Markets in Which We Operate — Our business and financial performance may be harmed by future labor disruptions."

Our business, financial condition, results of operations and liquidity are subject to various risks and uncertainties, including those described below, and as a result, the trading price of our common stock could decline. You should read the following risk factors carefully in connection with evaluating the Company’s business and the forward-looking information contained in this Annual Report. Any of the following risks and uncertainties could materially and adversely affect our business, financial condition, or operating results. While the Company believes it has identified and discussed below the key risk factors affecting our business, there may be additional risks and uncertainties that the Company does not presently know or that does not currently believe to be significant that may adversely affect our business, financial condition or operating results in the future.

TRANSACTION RISK FACTORS

We may not realize the expected benefits of the acquisition of the Augusta Facility because of integration difficulties or other challenges.

Our long-term growth strategy involves strengthening our position as a premier, independent supplier of paperboard products to North American converters. On May 1, 2024, we completed the purchase of the consumer packaging business operating out of the paperboard mills and associated facilities in Augusta, Georgia (the “Augusta Facility”) from Graphic Packaging International, LLC.

We may not be able to maintain the levels of revenue, earnings or operating efficiency that we estimate for the Augusta Facility. In addition, the success of the acquisition will depend, in part, on our ability to realize the anticipated benefits from the acquisition, including anticipated revenue, customer growth and cost structure and production scale benefits. The integration process has been and will continue to be complex, costly and time-consuming. The potential risks associated with our efforts to integrate the Augusta Facility operations and business include, among others:

• failure to implement effectively our business plan for the addition of the operations and business into our existing systems;
• unanticipated issues in integrating financial, manufacturing, logistics, information, information technology, communications and other systems;
• failure to retain key employees;
• failure to retain key customers;
• increased working capital needs, which could require additional debt and result in higher interest;
• inconsistencies in standards, controls, procedures and policies, including internal control and regulatory requirements under the Sarbanes-Oxley Act of 2002; and
• unanticipated issues, expenses and liabilities.

Further, the integration of the Augusta Facility requires the focused attention of our management team, including a significant commitment of their time and resources, which may divert management’s attention from other business concerns. The need for our management to focus on integration matters could have a material and adverse impact on our sales and operating results.

Any inability by us to integrate and manage the Augusta Facility, any inability to achieve anticipated revenues, cost savings or other anticipated benefits from the acquisition in the time frame we anticipate or any unanticipated required increases in capital spending could adversely affect our business, financial condition, results of operations or liquidity.

The Tissue Divestiture may disrupt our remaining business or not achieve its intended benefits.

On November 1, 2024, we completed the sale of our consumer products division to Sofidel America Corp. (the “Tissue Divestiture”). A number of risks and challenges may arise from the divestiture, including purchase price adjustments, unexpected costs, charges or expenses and disruption in our remaining business, including potential adverse changes to relationships with customers, employees, suppliers or other parties resulting from the divestiture process. The Tissue Divestiture may also be disruptive to our regular operations, diverting the attention of our workforce and management team from the day-to-day operation of our business, making the execution of business and other potential strategies more difficult, and could result in increased undesired workforce turnover, including of key leaders or other personnel.

We may not realize some or all of the anticipated benefits from the Tissue Divestiture with respect to the anticipated performance of our remaining business. The Company may experience continued financial exposure as a result of the Tissue Divestiture, through the retention of certain liabilities, including, for example, with respect to certain environmental claims. The Tissue Divestiture may not enhance long-term stockholder value as anticipated and/or the efforts required to complete the divestiture process may be more costly or time-consuming than expected. Any of the foregoing could result in the imposition of obligations that could have a material adverse effect on our business, operating results or financial condition.

We may incur significant costs or be unable to realize the expected benefits and long-term savings associated with our restructuring initiatives.

In response to the Tissue Divestiture, we have made and will continue to make certain changes to our functional and leadership structure to reduce operating expenses and adjust cash flows. Additional restructuring initiatives or changes to our functional and leadership structure may also be implemented in the future to align our operations with shifting demands in the markets in which we operate. These restructuring initiatives may include adjustments to our workplace policies and personnel strategy which could adversely impact our reputation and brand, and our ability to recruit, retain, train, and motivate highly skilled personnel. Such restructuring activities may also divert the attention of management and be disruptive to our business operations. While these initiatives are implemented to achieve long-term savings, we may incur significant short-term costs and there are no assurances that we will be able to realize all, or any, of the expected benefits.

Following the Tissue Divestiture, we share certain facilities in Lewiston, Idaho with Sofidel and we are required to provide certain services to Sofidel related to such shared facilities. Our relationship with Sofidel may impact our ability to conduct business at our Lewiston mill solely for our benefit.

Following the Tissue Divestiture, we share certain facilities located in Lewiston, Idaho with an affiliate of Sofidel America Corp. (together with such affiliate, “Sofidel”). We are party to a Services and Use Rights Agreement with Sofidel, pursuant to which we provide certain supplies and services to Sofidel in connection with its operations at such shared facility. Given the terms of this arrangement, operation of the Lewiston facility requires additional organizational formalities and procedures for decision-making on site. In certain circumstances, we must consult with Sofidel to reach a common view on operational matters affecting both portions of the Lewiston facility. Our inability to take unilateral actions at the Lewiston facility could have an adverse effect on our business, operating results or financial condition. We may also be exposed to unexpected risks associated with Sofidel’s operations at the Lewiston facility over which we have little control.

The Tissue Divestiture changes our exposure to other risks and uncertainties.

As a result of the Tissue Divestiture, our pulp and paperboard segment is our only line of business, and thus we are a smaller and more narrowly-focused business than prior to the Tissue Divestiture. Due to this lack of diversification, any adverse developments in the pulp and paperboard industry could have a significantly greater impact on our overall financial condition and results of operations than if we maintained multiple lines of business.

RISKS RELATED TO OUR BUSINESS OPERATIONS AND THE MARKETS IN WHICH WE OPERATE

Difficult industry and market conditions may adversely affect the operating results and cash flows of our business.

Difficult industry and market conditions may adversely affect our utilization rates due to decreases in product demand. During such periods, our facilities may not operate at full capacity or may need to take production downtime. During periods of lower capacity utilization and production downtimes, we not only experience lost revenue from lower shipment volumes but are also forced to continue to incur our fixed manufacturing costs, which are not absorbed by our lower production levels. Our results of operations and cash flows may be materially adversely affected in a period of prolonged and significant market weakness. We are not able to predict market conditions or our ability to sustain pricing and production levels during periods of weak demand.

For example, demand for our paperboard products surged during and following the COVID-19 pandemic, due to increased packaging and other usage of paperboard needed to address substantially higher consumer activity. In response to this demand, our customers added to their paperboard inventories. As consumer activity leveled out, our customers deployed their inventories to address their paperboard needs, leading to an overall decline in paperboard demand and prices in 2023 and 2024. If this trend continues, we may experience a further decline in paperboard demand, we may be unable to sustain pricing, and we may need to take production downtime.

The loss of, or a significant reduction in, orders from, or changes in prices in regard to, any of our large customers could adversely affect our operating results and financial condition.

We derive a substantial amount of revenue from a concentrated group of customers. Our top 10 paperboard customers accounted for 45% of our sales in 2024. If we lose any of these customers or a substantial portion of their business or if the terms of our relationship with any of them becomes less favorable to us, our net sales would decline, which would harm our results of operations and financial condition. In 2024, we experienced increased price competition in our paperboard business along with a significant drop in demand due to market conditions. This competition and the decline in demand has resulted in a decrease in our paperboard revenue and gross margins and adversely affected our financial condition.

Our agreements with our customers, including our largest customers, are not exclusive and generally do not contain minimum volume purchase commitments. Our relationships with our largest and most important customers will depend on their needs for quality products and services, and our ability to continue to meet these needs at competitive prices. If we lose one or more of our large customers or if we experience a significant decline in the level of purchases by any of them, we may not be able to quickly replace the lost business volume, and our operating results and business could be harmed.

Increases in paperboard supply could adversely affect our operating results and financial condition.

We expect increased competition in North America from both foreign and domestic manufacturers. We have experienced, and expect to continue to experience, increased direct sales by foreign competitors in the markets in which we compete. In addition, as a result of increased sales by foreign suppliers into the Asian and European markets, we expect domestic manufacturers to seek to increase their sales in the United States to offset displaced overseas sales.

Several significant investments in paperboard manufacturing facilities in North America and globally have been announced, which could significantly increase the production and supply of Solid Bleached Sulfate (SBS) and Folding Boxboard (FBB) paperboard in the market. If demand does not increase commensurate with supply, it could result in lower capacity utilization and effect the price of SBS, which could materially and adversely affect our results of operations and cash flows.

Substitution amongst paperboard grades could have an adverse effect on our financial results.

We currently manufacture only SBS paperboard. In addition to non-paper-based packaging substitutes for paperboard, there are other grades or substrates of paperboard, including FBB, Coated Recycled Board (CRB), and Coated Unbleached Kraft (CUK) paperboard, which are or can be substituted for SBS paperboard. If demand for SBS paperboard declines as a result of customer or consumer preference for these substitute products, or more generally, we may lose business or may not be able to grow our existing paperboard business, and we may be forced to sell at lower margins, all of which could negatively affect our financial condition and results of operations.

Consolidation in the North American paperboard and converting industry may adversely affect our business.

The ongoing consolidation of paperboard and paperboard converting businesses, including through the acquisition and integration of such converting businesses by competitors of ours, could result in a loss of customers and sales. A loss of customers or sales as a result of consolidations and integrations could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our products are vulnerable to declines in demand due to a shift in consumer preference for competing, sustainable materials which may have an adverse effect on our business.

Consumer preferences are increasingly shaped by concerns over post-consumer waste, packaging sustainability, and the environmental impact of materials. The demand for recyclable and eco-friendly packaging represents a significant trend, requiring us to focus on developing innovative, sustainable consumer packaging solutions to help customers achieve their packaging sustainability goals. However, responding to these goals involves risks and uncertainties, as these efforts require substantial investment and may involve significant changes to our manufacturing facilities and processes. The inability to innovate our products effectively or respond adequately to changes in consumer preference could result in financial and operational challenges.

Cyclical industry conditions have in the past affected and may continue to adversely affect the operating results and cash flows of our business.

Our business has historically been affected by cyclical market conditions. We may be unable to sustain pricing in the face of weaker demand, and weaker demand may in turn cause us to take production downtime. In addition to lost revenue from lower shipment volumes, production downtime causes unabsorbed fixed manufacturing costs due to lower production levels. Our results of operations and cash flows may be materially adversely affected in a period of prolonged and significant market weakness. We are not able to predict market conditions or our ability to sustain pricing and production levels during periods of weak demand.

We incur significant expenses to maintain our manufacturing equipment and any interruption in the operations of our facilities may harm our operating performance.

We regularly incur significant expenses to maintain our manufacturing equipment and facilities. The machines and equipment that we use to produce our products are complex, interdependent, have many parts and some are run on a continuous basis. We must perform routine maintenance on our equipment and have to periodically replace a variety of parts such as motors, pumps, pipes and electrical parts. In addition, our facilities require periodic shutdowns to perform major maintenance, during which we may discover additional maintenance or equipment issues that need to be addressed. These scheduled shutdowns of facilities result in decreased sales and increased costs in the periods in which they occur and could result in unexpected operational issues during the restart of a facility or in future periods as a result of changes to equipment and operational and mechanical processes made during the shutdown period.

Unexpected production disruptions could cause us to shut down or curtail operations at any of our facilities. Disruptions could occur due to any number of circumstances, including prolonged power outages, mechanical or process failures, faults in aging equipment, shortages of raw materials, natural catastrophes, disruptions in the availability of transportation, labor disputes, cyber-attacks and malware, terrorism, changes in or non-compliance with environmental or safety laws, and the lack of availability of services from any of our facilities key suppliers. For example, in the fourth quarter of 2023, we were forced to partially shut down parts of our mill and curtail production at our Idaho facility due to damage to a natural gas pipeline that supplied the region. Any facility shutdowns may be followed by prolonged startup periods, regardless of the reason for the shutdown. Those startup periods could range from several days to several weeks, depending on the reason for the shutdown and other factors. Any prolonged disruption in operations at any of our facilities could cause significant lost production, which would have a material adverse effect on our results of operations.

We depend on external sources of wood fiber which exposes our business and results of operations to potentially significant supply and price fluctuations.

Wood fiber is the principal raw material used to create wood pulp, which in turn is used to manufacture our pulp and paperboard products. Wood fiber pricing is subject to regional market influences, and our cost of wood fiber may increase in the areas our facilities are located due to market shifts in those regions. For example, much of the wood fiber we use in our pulp manufacturing process at our Lewiston, Idaho facility, is the by-product of sawmill operations. As a result, the price of these residual wood fibers is affected by operating levels in both the pulp and paperboard and lumber industries, which in the case of the latter is impacted by regional new home construction as well as home remodeling and repairs. During the past decade, many sawmills in the western United States have closed or curtailed operations or their operations have been consolidated. Additionally, the ability of paper and wood pellet mills in British Columbia to acquire wood fiber from the U.S. Inland Northwest region with limited to no reciprocal ability by U.S. mills to acquire wood fiber from British Columbia, reduces the supply of, and increases the costs for, wood fiber. The price of wood fiber in the Pacific Northwest is expected to remain volatile. Our Arkansas and Augusta pulp and paperboard facilities rely on whole log chips for a significant portion of their wood fiber, the supply of which can be negatively affected by regional demand from other paper or wood product manufacturing facilities as well as adverse weather conditions and reductions in logging companies.

The primary source for wood fiber is timber, the availability of which may be limited by adverse weather, fire, insect infestation, disease, ice storms, windstorms, flooding and other natural and man-made causes, thereby reducing supply and increasing prices.

The effects on market prices for wood fiber resulting from various governmental programs involving tax credits or payments related to biomass and other renewable energy projects or from environmental litigation or regulation are uncertain and could result in a reduction in the supply of wood fiber available for our pulp and paperboard manufacturing operations. Additionally, wood pellet and pulp facilities can increase demand and prices for wood fiber. If we and our pulp suppliers are unable to obtain wood fiber at favorable prices or at all, our costs will increase, and our operations and financial results may be harmed.

The cost and availability of chemicals and energy needed for our manufacturing processes significantly affects our results of operations and cash flows.

We use a variety of chemicals in our manufacturing processes, including petroleum-based polyethylene and certain petroleum-based latex chemicals. Prices for these chemicals have been and are expected to remain volatile. In addition, chemical suppliers that use petroleum-based products in the manufacture of their chemicals may, due to supply shortages and cost increases, ration the amount of chemicals available to us, and therefore we may not be able to obtain at favorable prices the chemicals we need to operate our business, if we are able to obtain them at all. Additionally, our facilities rely on imported raw materials and energy, including market pulp, natural gas, bulk chemicals and other commodities required to manufacture our products that could be impacted by tariffs on imported goods. Any significant disruption in the supply of, or significant cost increase in our manufacturing inputs, caused by tariffs or otherwise, in circumstances where we cannot raise the price of our products, could have a material adverse effect on our results of operations, affect our ability to meet customer demand in a timely manner and harm our reputation and our business.

Our manufacturing operations also utilize large amounts of electricity and natural gas. Energy prices have fluctuated widely over the past decade, which in turn affects our operational costs. We purchase on the open market a substantial portion of the natural gas necessary to produce our products, and, as a result, the price and other terms of those purchases are subject to change based on factors such as worldwide supply and demand, geopolitical events, government regulation, weather, interruptions in pipeline and other delivery systems, and natural disasters. Our energy costs in future periods will depend principally on our ability to produce a substantial portion of our electricity needs internally, on changes in market prices for natural gas and on reducing energy usage. Any significant energy shortage, or significant increase in our energy costs, in circumstances where we cannot raise the price of our products, could have a material adverse effect on our results of operations. Any disruption in the supply of energy could also affect our ability to meet customer demand in a timely manner and could harm our reputation and our business.

Disruptions in transportation services or increases in our freight costs could have a material adverse effect on our business.

Our business is dependent on transportation services to deliver our products to our customers and to deliver raw materials to us. Shipments of products and raw materials may be delayed or disrupted due to weather conditions, labor shortages or strikes, regulatory actions or other events. If our transportation providers are unavailable or fail to deliver our products in a timely manner, we may incur increased costs and we may be unable to manufacture and deliver our products on a timely basis. For example, in 2022, we experienced both difficulties in procuring sufficient transportation for shipments as well as significant increases in freight costs due to a number of factors.

The costs of these transportation services are also affected by geopolitical, economic and weather-related events. We have not been able in the past, and may not be able in the future, to pass part or all of any fuel price increases through to customers. Any increased fuel or freight costs, in circumstances where we cannot raise the price of our products, could have a material adverse effect on our gross margins.

Larger competitors have operational and other advantages over our operations.

The markets for our products are highly competitive, and companies that have substantially greater financial resources compete with us in each market. Some of our competitors have advantages over us, including lower raw material and labor costs and better access to the inputs of our products.

Our ability to successfully compete in the pulp and paperboard industry is influenced by a number of factors, including manufacturing capacity, general economic conditions and the availability and demand for paperboard substitutes. Our business competes with Smurfit Westrock, Georgia-Pacific, Graphic Packaging, Sappi and other international producers, most of whom are much larger than us. Any increase in manufacturing capacity by any of these or other producers could result in overcapacity in the pulp and paperboard industry, which could cause downward pressure on pricing.

Our business and financial performance may be harmed by future labor disruptions.

As of December 31, 2024, approximately 1,400 of our full-time employees were represented by unions under collective bargaining agreements. As these agreements expire, we may not be able to negotiate extensions or replacement agreements on terms acceptable to us. If such workers were to engage in a strike, lockout, work slowdown, stoppage or other labor action, or if other employees were to become unionized, we could experience a significant disruption of our operations and/or higher ongoing labor costs, which could adversely affect our business, financial condition and results of operations.

In August 2025, a collective bargaining agreement for hourly employees at our Lewiston, Idaho facility, which affects approximately 500 employees, will expire. Any failure to reach an agreement with one of the unions may result in strikes, lockouts, work slowdowns, stoppages or other labor actions, any of which could have a material adverse effect on our operations and financial results.

We rely on a limited number of third-party suppliers, vendors and service providers required for the production of our

products and our operations.

Our dependence on a limited number of third-party suppliers, and the challenges we may face in obtaining adequate supplies of raw materials, involve several risks, including limited control over pricing, availability, quality and delivery schedules. Limitations on the availability of, and subsequent increases in, the costs of raw materials could have an adverse effect on our financial results. We cannot be certain that our current suppliers will continue to provide us with the quantities of these raw materials that we require or will continue to satisfy our anticipated specifications and quality requirements. Any supply interruption in limited raw materials could materially harm our ability to manufacture our products until a new source of supply, if any, could be identified and qualified. Although we believe there are other suppliers of these raw materials, we may be unable to find a sufficient alternative supply channel in a reasonable time or on commercially reasonable terms.

We also depend on a limited number of third-party vendors for certain of our operating equipment and spare parts as well as service providers. Any performance failure on the part of our suppliers or vendors could interrupt production of our products, which would have a material adverse effect on our business.

We rely on information technology in critical areas of our operations, and a disruption relating to such technology could harm our financial condition.

We use information technology, or IT, systems in various aspects of our operations, including enterprise resource planning, management of inventories, manufacturing, supply chain and customer sales. We have different legacy IT systems that we are continuing to integrate, upgrade and move to the cloud. If one of these systems were to fail or cause operational or reporting interruptions, or if we decide to change these systems or hire outside parties to provide these systems, we may suffer disruptions, which could have a material adverse effect on our manufacturing and sales operation, results of operations and financial condition. In addition, we may underestimate the costs, complexity and time required to develop and implement new systems and operating technology systems that control our manufacturing equipment and facilities and are embedded in our plant networks.

We face cyber-security risks.

Our business operations rely upon secure information technology systems for data capture, processing, storage and reporting. Despite careful security and controls design, implementation and updating, our information technology systems or plant networks could become subject to cyber-attacks. We may not have the resources or technical sophistication to anticipate or prevent all such cyber-attacks. Moreover, techniques used to obtain unauthorized access to systems change frequently and may not be known until launched against us. Security breaches can also occur as a result of nontechnical issues, including intentional or inadvertent breaches by our employees. Network, system, application and data breaches could result in operational disruptions or information misappropriation, which could result in lost sales, production interruption, financial losses, business delays, negative publicity, and could have a material adverse effect on our business, results of operations and financial condition.

We are subject to significant environmental regulation and environmental compliance expenditures, which could increase our costs and subject us to liabilities.

We are subject to various federal, state and foreign environmental laws and regulations concerning, among other things, water discharges, air emissions, hazardous material and waste management and environmental cleanup. Environmental laws and regulations continue to evolve and we may become subject to increasingly stringent environmental standards in the future, particularly under laws and standards related to air quality, water quality, product composition and climate change issues. In particular, greenhouse gas emissions have increasingly become the subject of political and regulatory focus and this may lead to changes in legislative and regulatory initiatives directed at limiting greenhouse emissions.

Increased regulatory activity at the state, federal and international level is possible regarding climate change as well as other emerging environmental issues associated with our manufacturing sites and products, such as water quality standards, dam breaching for purposes of aiding salmon recovery in the Pacific Northwest, or recycling. Such new public policy or compliance with regulations that implement new public policy in these areas might require significant expenditures on our part or even the curtailment of certain of our manufacturing operations.

We could also incur substantial fines or sanctions, enforcement actions, damage claims, cleanup costs, third-party claims for property damage and personal injury, and reputational harm as a result of violations of, or liabilities under, environmental laws, regulations, codes and common law. The amount and timing of environmental expenditures is difficult to predict, and, in some cases, liability may be imposed without regard to contribution or to whether we knew of, or caused, the release of hazardous substances.

We are required to comply with environmental laws and the terms and conditions of multiple environmental permits. In particular, the pulp and paperboard industry in the United States is subject to several performance based rules associated with effluent and air emissions as a result of certain of its manufacturing processes. Federal, state and local laws and regulations require us to routinely obtain authorizations from and comply with the evolving standards of the appropriate governmental authorities, which have considerable discretion over the terms of permits. Failure to comply with environmental laws and permit requirements could result in civil or criminal fines or penalties or enforcement actions, including regulatory or judicial orders enjoining or curtailing our operations or requiring us to take corrective measures, install pollution control equipment, or take other remedial actions, such as product recalls or labeling changes. We also may be required to make additional expenditures, which could be significant, relating to environmental matters on an ongoing basis. There can be no assurance that future environmental permits will be granted or that we will be able to maintain and renew existing permits, and the failure to do so could have a material adverse effect on our results of operations, financial condition and cash flows.

We own properties, conduct or have conducted operations at properties, and have assumed indemnity obligations for properties or operations where hazardous materials have been or were used for many years, including during periods before careful management of these materials was required or generally believed to be necessary. Consequently, we will continue to be subject to risks under environmental laws that impose liability for historical releases of hazardous substances and to liability for other potential violations of environmental laws or permits at existing sites or ones for which we have indemnity obligations.

We may be subject to operational and financial climate change risks.

Extreme weather-related events caused by climate change, such as prolonged, extreme high or low temperatures, extreme storms, floods and decreased or curtailed water supplies, could result in physical damage to our facilities and operations. Such events may also result in supply chain disruptions and increased costs. For example, in the first quarter of 2024, extreme cold and related natural gas supply issues resulted in the shutdown of our Lewiston, Idaho mill and in the fourth quarter of 2024, impacts from Hurricane Helene resulted in the temporary suspension of operations at our Augusta, Georgia facility.

The ability to harvest the wood fiber used in our manufacturing operations may be limited, and prices could become volatile, because of variations in weather, wildfires, and climate conditions. Damage or disruptions we may incur because of climate-related risks could have a material adverse effect on our manufacturing and sales operations, results of operations and financial condition. In addition, we may underestimate the costs, complexity and time required to develop and implement mitigation efforts to address potential climate change impacts.

Our operations require substantial capital and our capital expenditures may not achieve the desired outcomes or may be achieved at a higher cost than anticipated.

Our business is capital intensive and we regularly make capital expenditures to maintain our equipment, improve our operating efficiency, comply with environmental laws, and innovate to remain competitive. Many of our capital projects are complex, costly, and implemented over an extended period of time. We may experience higher expenditures than anticipated for particular capital projects as well as unanticipated business disruptions, and we may not achieve the desired benefits from a given project, any of which could adversely affect our business, financial condition, results of operations and cash flows. In addition, disputes between us and contractors who are involved with implementing capital projects could lead to time-consuming and costly litigation.

We may face demand, supply, and operational challenges associated with effects of a disease outbreak, including epidemics, pandemics, or similar widespread public health concerns.

Our business and financial results may be negatively impacted by health epidemics, pandemics and similar widespread public health concerns or outbreaks. Despite our efforts to manage these impacts, their ultimate impact also depends on factors beyond our knowledge or control, including the duration and severity of any such outbreak and actions taken to contain its spread and mitigate its public health effects.

We are exposed to lawsuits, governmental investigations and proceedings relating to current and historical operations and products, which could harm our business.

From time to time, the nature of our business exposes us to certain lawsuits, governmental investigations and proceedings relating to current and historical operations and products, which may include claims involving product liability, environmental compliance, hazardous materials, infringement of intellectual property rights of third parties, workplace safety, employment and other claims. While we have in place processes and policies to mitigate these risks and to investigate and address such claims as they may arise, we cannot predict the underlying costs to defend or resolve such claims and any adverse rulings or results could have a material adverse effect on our business, financial condition, or results of operations.

We could be subject to changes in tax rates, the adoption of new tax laws or interpretations, or exposure to additional tax liabilities.

We are subject to income and other taxes in the U.S. Tax laws are dynamic and subject to change as new laws are passed and new interpretations of the law are issued or applied. Significant judgment is required in estimating our provision for income taxes. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. Although we believe our tax estimates are reasonable, any final determination pursuant to tax audits and any related litigation could be materially different to the amounts reflected in our financial statements. Should any tax authority disagree with our estimates and determine any additional tax liabilities, including interest and penalties for us, this could adversely impact our results of operations, financial position and cash flows.

If we are unable to continue to implement our business plan and strategic initiatives, our financial condition and operating results could be materially affected.

Our future operating results will depend, in part, on the extent to which we can successfully implement our business plan and strategic initiatives in a cost effective manner. We pursue strategic initiatives that management considers important to our long-term success, including mergers and acquisitions, dispositions and restructuring activity. There are risks involved with the execution of such initiatives, including significant business, economic and competitive uncertainties, many of which are beyond our control, including those associated with the global macro-environment in which we operate, trends in our industry, demand for our products, competitive threats, product innovation, public policy developments, changes to consumption habits, and resource allocation. If we are unable to successfully implement our business plan or strategic initiatives, our business, financial condition and operating results could be materially and adversely affected.

Additionally, we may enhance, modify or build manufacturing facilities as part of our strategic initiatives. We may be unable to identify future suitable strategic capital or building projects or may be unable to achieve anticipated benefits or cost savings from construction projects in the timeframe we anticipate, or at all. Large construction projects or acquisitions can result in a decrease in our cash and short-term investments, an increase in our indebtedness, or both, and also may limit our ability to access additional capital when needed and divert management's attention from other business concerns.

RISKS RELATED TO OUR EMPLOYEE PLANS

We may be required to pay material amounts to multiemployer pension plans; our participation subjects us to potential liabilities, which could be significant, if we withdraw from a plan in the future.

We contribute to two multiemployer pension plans. The amount of our annual contributions to these plans is negotiated with the union representing our employees covered by each plan. In 2024, we contributed approximately $5.8 million to these plans. If in future years we continue to participate in these plans, we may be required to make increased annual contributions in amounts that are difficult to predict and potentially beyond our control, which would reduce the cash available for business and other needs. The decision whether to continue to participate in these multiemployer plans does not rest solely with us; rather, it is negotiated as part of the collective bargaining agreements with labor unions that participate in these plans.

If we were to withdraw partially or completely from a multiemployer plan that is underfunded, we would be liable for a proportionate share of that plan’s unfunded vested benefits as required by law. This is called withdrawal liability. The amount of withdrawal liability, if any, assessable to us if we were to withdraw in a future year is difficult to predict and largely beyond our control.

One of the multiemployer pension plans to which we contribute, the IAM National Pension Fund, or IAM NPF, elected to be certified in “critical status” for the plan year beginning January 1, 2019. If we were to withdraw from IAM NPF, either completely or partially, we would incur a statutory withdrawal liability based on our proportionate share of IAM NPF’s unfunded vested benefits. Based on information available to us, as well as information provided by IAM NPF, and reviewed by our actuarial consultant, we estimate that, as of December 31, 2024, we would be obligated to pay a single sum withdrawal liability payment of approximately $4.9 million on a pretax basis if we were to have completely withdrawn from IAM NPF in 2024. We currently have no plans to withdraw from IAM NPF and have not recognized any liability associated with a withdrawal from IAM NPF in our consolidated financial statements.

The other multiemployer pension plan to which we contribute, the PACE Industry Union-Management Pension Fund, or PIUMPF, was certified to be in “critical status” for the plan year beginning January 1, 2010 and continued to be in critical status through the plan year beginning January 1, 2014. For the plan years beginning January 1, 2015 through January 1, 2023, PIUMPF was certified to be in “critical and declining status” under the Multiemployer Pension Reform Act of 2014. The number of employers participating in PIUMPF fell from 135 during 2012 to 42 in 2023. We were the largest contributing employer participating in PIUMPF in 2024.

The American Rescue Plan Act of 2021, or ARPA, includes provisions to provide financial relief to financially troubled multiemployer pension plans. In 2023, PIUMPF applied for and received approximately $1.3 billion in a lump sum payment under this program — an amount intended to allow it to remain solvent until approximately 2051.

If we were to withdraw from PIUMPF, either completely or partially, we would incur a statutory withdrawal liability based on our proportionate share of PIUMPF’s unfunded vested benefits. Based on information available to us, as well as information provided by PIUMPF, and reviewed by our actuarial consultant, we estimate that, as of December 31, 2024, the withdrawal liability payments that we would be required to make to PIUMPF were we to have completely withdrawn in 2024 would be approximately $5.7 million per year on a pretax basis. These payments generally would continue for 20 years with an estimated present value of approximately $70 million on a pre-tax basis. We expect that all other things being equal, the receipt of ARPA funds has eliminated PIUMPF’s unfunded vested benefits. Because the ARPA funds must be “phased in” over the period of time such funds are expected to be utilized, however, we expect any potential withdrawal liability will be significantly reduced annually and ultimately eliminated over an extended period.

Were we voluntarily to withdraw from PIUMPF, we could be subject to substantial payments in addition to the withdrawal liability payments described above. As a plan in critical and declining status, PIUMPF has adopted a rehabilitation plan. That rehabilitation plan purports to require a withdrawing employer to make an additional, lump-sum payment — above and beyond the statutory withdrawal liability — based on the employer’s share of PIUMPF’s accumulated funding deficiency, or AFD.

We believe PIUMPF’s purported imposition of this AFD exit fee on withdrawing employers is not legally enforceable — and that PIUMPF’s receipt of approximately $1.3 billion in lump sum financial relief from the federal government (through the ARPA program) provides additional support for this belief. Among other things, since it was enacted, PIUMPF’s sole justification for imposition of the AFD exit fee is that it was necessary to forestall PIUMPF’s insolvency — a justification that no longer applies now that PIUMPF has received funds under the ARPA program that have addressed its solvency crisis.

Nevertheless, we are aware that one large employer that withdrew from PIUMPF prior to PIUMPF’s receipt of ARPA funds has recognized a liability for payment of an AFD exit fee amount and that other withdrawing employers have paid some amounts in respect to the AFD exit fee. There have been lawsuits in federal courts challenging PIUMPF’s AFD exit fee. These lawsuits have not resolved the issue.

If the AFD exit fee were held to be legally enforceable, and if we were to withdraw in a future year, the amount of our AFD exit fee liability at the time of our withdrawal could be material and would be subject to a variety of factors, including without limitation, the nature and timing of a withdrawal, the financial health of PIUMPF at the time of the withdrawal, the level of contributions to the plan made by other contributing employers before our withdrawal, whether any employers that had withdrawn in the intervening years had made AFD exit fee payments, the success of the potential legal challenges we could raise and the effect of funding provided under ARPA. PIUMPF’s receipt of approximately $1.3 billion in ARPA funds is more than enough to eliminate PIUMPF’s AFD. However, due to regulatory and accounting requirements, the impact of the ARPA funding will be effectively phased in over time, and we expect that this will result in the substantial reduction annually and ultimate elimination of any potential AFD exit fee exposure over an extended period.

As we currently have no plans to withdraw from PIUMPF, we have not recognized any liability associated with a withdrawal from PIUMPF in our consolidated financial statements.

Adverse changes to, or requirements under, pension laws and regulations or adverse changes, requirements or claims pursuant to PIUMPF’s rehabilitation plan, such as the AFD exit fee, could increase the likelihood and amount of our liabilities. Were we to withdraw from PIUMPF, these liabilities would be in addition to the pension contributions we would have to make to any new pension plan adopted or contributed to by us to replace PIUMPF. All of this could materially reduce the cash we would have available for business and other needs.

Our pension and health care costs are subject to numerous factors that could cause these costs to change.

In addition to our pension plans, we provide health care benefits to certain of our current and former salaried and hourly employees. Our health care costs vary with changes in health care costs generally, which have significantly exceeded general economic inflation rates for many years. Our pension costs are dependent upon numerous factors resulting from actual plan experience and assumptions about future investment returns. Pension plan assets are primarily made up of equity and fixed income investments. Fluctuations in actual equity market returns as well as changes in general interest rates may result in increased pension costs in future periods. Likewise, changes in assumptions regarding current discount rates, expected rates of return on plan assets and mortality rates could also increase pension costs. Significant changes in any of these factors may adversely impact our cash flows, financial condition and results of operations.

RISKS RELATED TO OUR INDEBTEDNESS

Despite our current indebtedness levels, we may still incur significant additional indebtedness. Incurring more indebtedness could increase the risks associated with our substantial indebtedness.

We may be able to incur substantial additional indebtedness, including additional secured indebtedness, in the future. The terms of the Credit Agreements restrict but do not prohibit us from doing so. We had availability of approximately $270 million under our PCA Credit Agreement as of December 31, 2024. After giving effect to borrowing base limitations and issuance of letters of credit, we had availability of approximately $218 million under the Credit Agreement as of December 31, 2024. In addition, our Credit Agreements allow us to obtain additional secured revolving loan commitments under our ABL Credit Agreement and additional term revolver commitments under our PCA Credit Agreement, in each case, under certain circumstances, which would be guaranteed by our subsidiary guarantors. In addition, the indenture governing our notes does not prevent us from incurring certain other liabilities that do not constitute secured indebtedness. If new debt or other liabilities are added to our current debt levels, the related risks that we and our subsidiaries now face could intensify.

If we default under our Credit Agreements, or other indebtedness, we may not be able to service our debt obligations.

In the event of a default under our Credit Agreements or other indebtedness, lenders could elect to declare all amounts borrowed, together with accrued and unpaid interest and other fees, to be due and payable. If such acceleration occurs, thereby permitting an acceleration of amounts outstanding under our debt obligations, we may not be able to repay the amounts due. Events of default are separately defined in each credit agreement or indenture, but include events such as failure to make payments when due, breach of covenants, default under certain other indebtedness, failure to satisfy judgments in excess of a threshold amount, certain insolvency events and the occurrence of a change of control (as defined in the Credit Agreements). The occurrence of an event of default could have serious consequences to our financial condition and results of operations and could cause us to become bankrupt or insolvent.

To service our existing and future indebtedness, we must generate cash flows. Our ability to generate cash depends on many factors beyond our control, and we may be forced to take other actions to satisfy our obligations under our indebtedness, which may not be successful.

As of December 31, 2024, we had approximately $275 million of outstanding indebtedness, and we could incur substantial additional indebtedness in the future. Our ability to make scheduled payments on or to refinance our indebtedness, including our outstanding notes, and to fund planned capital expenditures, will depend on our ability to generate cash from our operations. This, to a significant extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.

We cannot assure you that our business will generate sufficient cash flows from operations or that future borrowings will be available to us under our Credit Agreements in an amount sufficient to enable us to pay our indebtedness, including our outstanding notes, or to fund our other liquidity needs. We cannot assure you that we will be able to refinance any of our indebtedness, including our Credit Agreements and our outstanding notes, on commercially reasonable terms or at all.

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay investments and capital expenditures, or to sell assets, seek additional capital or restructure or refinance our indebtedness. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations. If our operating results and available cash are insufficient to meet our debt service obligations, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet our debt service and other obligations. We may not be able to consummate those dispositions or to obtain the proceeds that we could realize from them, and these proceeds may not be adequate to meet any debt service obligations then due. Additionally, our debt agreements limit the use of the proceeds from certain dispositions; as a result, we may not be allowed, under these documents, to use proceeds from such dispositions to satisfy all current debt service obligations.

Our Credit Agreements contain various covenants that limit our discretion in the operation of our business.

Our Credit Agreements contain various covenants that limit our discretion in the operation of our business by restricting our ability to:

• undergo a change in control;
• sell assets;
• pay dividends and make other distributions;
• make investments, capital expenditures and other restricted payments;
• redeem or repurchase our capital stock;
• incur additional debt and issue preferred stock;
• guarantee indebtedness;
• create liens;
• consolidate, merge or sell substantially all of our assets;
• enter into certain transactions with our affiliates;
• engage in new lines of business; and
• enter into sale and lease-back transactions.

These restrictions on our ability to operate our business at our discretion could materially harm our business by, among other things, limiting our ability to enter into, make, or borrow in order to take advantage of financing opportunities with respect to mergers and acquisitions, capital expenditures and other corporate opportunities.

If and when (and for as long as) availability, as calculated, under the ABL Credit Agreement is less than a specified amount for a certain period of time, funds deposited into deposit accounts used for collections would be transferred on a daily basis into a blocked account with the administrative agent and applied to prepay loans under the ABL Credit Agreement. If and when our leverage ratio, as calculated under the PCA Credit Agreement, is greater than a specified amount (and lasting until at least the end of two fiscal quarters until our leverage ratio is less than such amount), the amount of dividends, stock repurchases, capital expenditures and other investments we would be permitted to make in the then current fiscal year would be capped at specified dollar amounts.

As a result of these covenants and restrictions, we may be limited in how we conduct our business and we may be unable to raise additional debt or equity financing to compete effectively or to take advantage of new business opportunities. The terms of any future indebtedness we may incur could include more restrictive covenants. We cannot assure you that we will be able to maintain compliance with these covenants in the future and, if we fail to do so, that we will be able to obtain waivers from the lenders and/or amend the covenants.

There are various limitations on our ability to incur the full $375 million of commitments under our ABL Credit Agreement and borrowings under our ABL Credit Agreement are limited by a specified borrowing base consisting of a percentage of eligible accounts receivable and inventory, less customary reserves. In addition, under the ABL Credit Agreement, a monthly fixed charge maintenance covenant would become applicable during an event of default or if availability, as calculated under the ABL Credit Agreement, is at any time less than or equal to the greater of (i) 10.0% of the lesser of the borrowing base and the maximum $375 million of current revolving loan commitments (such lesser amount, the “Line Cap”) and (ii) $25 million. As of December 31, 2024, availability under the ABL Credit Agreement was approximately $218 million or 10% % of the Line Cap. However, it is possible that availability, as calculated under the ABL Credit Agreement, could fall below the minimum threshold in a future period. If the covenant trigger were to occur, we would be required to satisfy and maintain on the last day of each quarter a fixed charge coverage ratio of at least 1.1x for the preceding four quarter period for which financial statements had been delivered. As of December 31, 2024, our fixed charge coverage ratio was approximately 2.0x. If and when the fixed charge coverage ratio were to be tested, our ability to meet the minimum fixed charge coverage ratio could be affected by events beyond our control, and we cannot assure you that we would meet this ratio at such time. A breach of any of these covenants could result in a default under the ABL Credit Agreement. Events beyond our control could affect our ability to meet these financial tests, and we cannot assure you that we will meet them.

Our failure to comply with the covenants contained in our Credit Agreements or the indenture governing our outstanding notes, including as a result of events beyond our control, could result in an event of default that could cause repayment of the debt to be accelerated.

If we are not able to comply with the covenants and other requirements contained in the indenture governing our outstanding notes, our Credit Agreements or our other debt instruments, an event of default under the relevant debt instrument could occur. If an event of default does occur, it could trigger a default under our other debt instruments, prohibit us from accessing additional borrowings, and permit the holders of the defaulted debt to declare amounts outstanding with respect to that debt to be immediately due and payable. Our assets and cash flow may not be sufficient to fully repay borrowings under our outstanding debt instruments. In addition, we may not be able to refinance or restructure the payments on the applicable debt. Even if we were able to secure additional financing, it may not be available on favorable terms.

Credit rating downgrades could increase our borrowing costs or otherwise adversely affect us.

Some of our outstanding indebtedness has received credit ratings from rating agencies. Our credit ratings could change based on, among other things, our results of operations and financial condition. Credit ratings are subject to ongoing evaluation by credit rating agencies and may be lowered, suspended or withdrawn entirely by a rating agency or placed on a “watch list” for a possible downgrade or assigned a “negative outlook.” Although our indebtedness does not include any triggers that would increase existing borrowing rates if there were a ratings downgrade, actual or anticipated changes or downgrades, including any announcement that our ratings are under review for a downgrade or have been assigned a negative outlook, could increase our future borrowing costs, which could in turn adversely affect our results of operations, cash flows and financial condition, and the trading price of our common stock. If a downgrade were to occur or a negative outlook were to be assigned, it could impact our ability to access the capital markets to raise debt and/or increase the associated costs. In addition, while our credit ratings are important to us, we may take actions and otherwise operate our business in a manner that adversely affects our credit ratings.

An increase in interest rates could have a negative effect on our business.

We have the ability to select the Secured Overnight Funding Rate (SOFR) as a benchmark rate at which outstanding obligations under the Credit Agreements are based. SOFR is a floating rate, subject to a minimum rate set in the Credit Agreements. As a result, we are exposed to risks associated with an increase in interest rates, including if the Federal Reserve raises interest rates as it has done and may continue to do so in the future. Any further increase in SOFR will increase the Company’s debt service obligations, which could have a negative impact on the Company’s cash flow, financial position or operating results, including cash available for servicing the Company’s indebtedness, or result in increased borrowing costs in the future. We may utilize derivative financial instruments, such as interest rate swaps, to manage our interest rate risk. There can be no assurance, however, that increases in interest rates will not adversely affect our business, financial position and results of operations by causing an increase in interest expense. Significantly higher interest rates may also, among other things, reduce the availability and increase the cost of obtaining new debt and refinancing existing indebtedness.

GENERAL RISK

United States and global economic conditions could have adverse effects on the demand for our products and financial results.

U.S. and global economic conditions and currency exchange rates have a significant impact on our business and financial results. Recessed global economic conditions and a strong U.S. dollar could affect our business in a number of ways, including causing declines in global demand for paperboard, and increased competition from foreign manufacturers in the U.S. market. Foreign currency changes can also impact pricing associated with our raw materials such as pulp and equipment purchases, impacting our cost structure.

Recent fluctuations in economic conditions and cycles may have adverse effects on our financial results.

During 2024, interest and inflation rates increased significantly relative to recent years, although the impacts were felt to different extents, and the far extent of such increases remains to be seen. Increasing rates may materially affect our prices and the demand for our products.

We may fail to attract, motivate, train and retain qualified personnel, including key personnel.

Our ability to effectively run our business depends on our ability to attract, motivate, train and retain employees with the skills necessary to understand and adapt to the competitive markets in which we operate. The increasing demand for qualified personnel makes it more difficult for us to attract and retain employees with requisite skill sets, particularly employees with specialized technical and trade experience, and can increase our operating and overhead costs. Changing demographics and labor work force trends also may result in a loss of knowledge and skills as experienced workers retire. If we fail to attract, motivate, train and retain qualified personnel, or if we experience excessive turnover, we may experience declining sales, manufacturing delays or other inefficiencies, increased recruiting, training and relocation costs and other difficulties, which may negatively impact our results of operations, cash flows and financial condition.

In addition, we rely on key executive and management personnel to manage our business efficiently and effectively. The loss of any of our key personnel could adversely affect our results of operations, cash flows and financial condition. Effective succession planning is also important to our long-term success. Our failure to identify candidates with the leadership skills to manage our organization, and our failure to ensure effective transfers of knowledge and smooth transitions involving key executives, could hinder our strategic planning and execution.

Certain provisions of our certificate of incorporation and bylaws and Delaware law may make it difficult for stockholders to change the composition of our Board of Directors and may discourage hostile takeover attempts that some of our stockholders may consider to be beneficial.

Certain provisions of our certificate of incorporation and bylaws and Delaware law may have the effect of delaying or preventing changes in control if our Board of Directors determines that such changes in control are not in the best interests of the Company and our stockholders. The provisions in our certificate of incorporation and bylaws include, among other things, the following:

• a classified Board of Directors with staggered terms (which shall cease to be classified after the 2027 annual meeting);
• the ability of our Board of Directors to issue shares of preferred stock and to determine the price and other terms, including preferences and voting rights, of those shares without stockholder approval;
• stockholder action can only be taken at a special or regular meeting and not by written consent;
• advance notice procedures for nominating candidates to our Board of Directors or presenting matters at stockholder meetings;
• removal of directors only for cause (except for directors elected following the 2025 annual meeting); and
• supermajority voting requirements to amend our bylaws and certain provisions of our certificate of incorporation.

While these provisions have the effect of encouraging persons seeking to acquire control of the Company to negotiate with our Board of Directors, they could enable the Board of Directors to hinder or frustrate a transaction that some, or a majority, of the stockholders might believe to be in their best interests and, in that case, may prevent or discourage attempts to remove and replace incumbent directors. We are also subject to Delaware laws that could have similar effects. One of these laws prohibits us from engaging in a business combination with a significant stockholder unless specific conditions are met.

Our cybersecurity program is managed by our Chief Information Officer (CIO), whose team is responsible for leading enterprise-wide information technology strategy, policy, standards, architecture, and processes. The CIO provides regular reports to our Board of Directors, Chief Executive Officer and other members of our senior leadership team. These reports include updates on our cyber risks and threats, the status of projects to strengthen our information security systems, assessments of the information security program, and the emerging threat landscape.

Assessing, identifying and managing cybersecurity related risks are integrated into our overall enterprise risk management (ERM) process. Cybersecurity related risks are included in the risk universe that the ERM function evaluates to assess top risks to the enterprise on an annual basis. The ERM process’s annual risk assessment is presented to the Board of Directors.

Our programs are regularly evaluated by external experts with the results of those reviews reported to the senior leadership team and the Board of Directors. We also actively engage with key vendors, industry participants, and intelligence communities as part of our continuing efforts to evaluate and enhance the effectiveness of our information security policies and procedures.

During 2024, we did not experience any cybersecurity threats that had a material impact or are reasonably likely to materially affect our business, results of operations or financial condition. However, despite our efforts, we cannot eliminate all risks from cybersecurity threats, or provide assurances that we have not experienced an undetected cybersecurity incident. Please see our "Risk Factors" in item 1A in this report for more information.

Facilities

Our principal executive offices are located in Spokane, Washington. We believe that each of these facilities is adequately maintained and is suitable for conducting our operations and business. Information regarding our principal facilities is set forth in the following table.

1 In the fourth quarter of 2024, we announced the permanent closure of our Richmond, Virginia sheeting operations. As market conditions warrant, we will be relocating existing equipment to a new location.

Production Capacities

Information regarding currently operating production capacities is based on annual, normal operating rates and normal production mixes under current market conditions, taking into account known constraints. Market conditions, fluctuations in raw material supply, environmental restrictions and the nature of current orders may cause actual production rates and mixes to vary significantly from the production rates and mixes shown.

21

We may from time to time be involved in claims, proceedings and litigation arising from our business and property ownership. We believe, based on currently available information, that the results of such proceedings, in the aggregate, will not have a material adverse effect on our financial condition, results of operations and cash flows.

In November 2023, the United States Environmental Protection Agency (EPA) alleged that the Company had violated the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and Emergency Planning and Community Right-to-Know Act (EPCRA) by failing to timely report certain chlorine releases that occurred at the Company’s facility in Lewiston, Idaho in 2019, 2020, and 2021 to the National Response Center and State Response Center. Although the Company reported each of the releases to the respective response centers, the EPA alleged that the Company should have reported sooner. In June 2024, the Company, without admitting any wrongdoing, settled the matter with the EPA and paid a $322,088 civil penalty.

In April 2024, the EPA alleged the Company violated the Risk Management Program (RMP) under Section 112r of the Clean Air Act by failing to sufficiently implement certain RMP elements for its pulp bleach system at the Company’s facility in Lewiston, Idaho. In February 2025 we reached a settlement with the EPA, resulting in an agreed civil penalty of $440,393. The Company did not admit any wrongdoing in connection with the settlement.

The following discussion and analysis should be read in conjunction with our audited consolidated financial statements and related notes that appear elsewhere in this report. This discussion contains forward-looking statements reflecting our current expectations that involve risks and uncertainties. Actual results may differ materially from those discussed in these forward-looking statements due to a number of factors, including those set forth in the section entitled “Risk Factors” and elsewhere in this report.

Overview of Business

We are a premier manufacturer and supplier of Solid Bleached Sulfate (SBS) paperboard packaging products to independent converters. We believe we are well positioned to capitalize on sustainability trends towards renewable and recyclable materials. We focus on food service and folding carton markets and provide limited distribution and sheeting services. Additionally, we sell minor amounts of pulp to outside customers. We believe our status as an independent, non-integrated supplier is core to our value proposition. We strive to develop new products and innovative solutions to expand and diversify our paperboard portfolio. In 2024, our business and production capabilities, we completed the acquisition of a paperboard manufacturing facility and associated business in Augusta Georgia.

Reclassification of Our Tissue Operations

In 2024, we completed the sale of our tissue operations. This sale represents a strategic shift in our operations and financial results requiring discontinued operations accounting treatment for this division. The financial information presented below reflects reclassifications from previously reported information based upon discontinued operations. Historically, we have shown certain intercompany pulp costs as offsets to cost of sales as they represented intercompany transactions between the tissue operations and the pulp and paperboard manufacturing operations. Based upon discontinued operations treatment, such transfers of pulp and other inputs have been recast to Net Sales on the Consolidated Statements of Operations.

Significant Factors That Impact Our Business and Results of Operations

The paperboard industry is affected by macro-economic conditions around the world and has historically experienced cyclical market conditions. As a result, prices for products and sales volumes have historically been volatile. Product pricing is significantly affected by the relationship between supply and demand for our products. Product supply in the industry is influenced primarily by fluctuations in available manufacturing production, which tends to increase during periods when prices remain strong. During 2023 and 2024, the paperboard industry saw significant weakness due to customer destocking after a lengthy period of constrained supply given high demand coupled with increasing supply.

Our operating costs include raw materials, labor and selling, general and administrative expenses. We manage these costs through cost saving and productivity initiatives, sourcing programs, and pricing actions. Additionally, our operations, as do all pulp and paperboard manufacturing operations, require regular planned maintenance outages. During 2024, we incurred planned maintenance outages at our Lewiston, Idaho and our Augusta, Georgia facilities. During 2023, we incurred a planned maintenance outage at our Cypress Bend, Arkansas facility. During 2022, we incurred a planned maintenance outage at our Lewiston, Idaho facility. Starting in 2025, we plan to move to annual outages for each of our facilities.

Critical Accounting Policies and Significant Estimates

A discussion of our significant accounting policies and significant accounting estimates and judgments is presented in Note 1, "Summary of Significant Accounting Policies" of the Notes to Consolidated Financial Statements in Item 8 of this report. Throughout the preparation of the financial statements, we employ significant judgments in the application of accounting principles and methods. We believe that the accounting estimates discussed below represent the accounting estimates requiring the exercise of judgment where a different set of judgments could result in the greatest changes to reported results. We reviewed the development, selection and disclosure of our critical accounting estimates with the Audit Committee of our Board of Directors. For 2024, these significant accounting estimates and judgments include:

Business Acquisitions

We use the acquisition method of accounting for acquired businesses. Under the acquisition method of accounting, we allocated the purchase consideration to the tangible assets acquired and liabilities assumed based on their estimated fair values on the date of the acquisition. Any excess of the purchase price over the estimated fair values of the identifiable net assets acquired is recorded as goodwill. The estimates used to determine the fair value of long-lived assets can be complex and require significant judgments. Therefore, we use information available to us to make fair value determinations and often engage independent valuation specialists, when necessary, to assist in the fair value determination of significant, acquired long-lived assets. The determination of fair value requires estimates about discount rates, growth and retention rates, expected future cash flows and other future events that are judgmental in nature. While we use our best estimates and assumptions as a part of the purchase price allocation process, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we are permitted to record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of income.

On May 1, 2024, we completed the acquisition of a paperboard manufacturing facility and associated business, located in Augusta, Georgia (Augusta) from Graphic Packaging International, LLC for cash of $708 million. Augusta’s results of operations have been included in our financial results since the acquisition date. We allocated the fair value of purchase consideration transferred to the tangible assets acquired and liabilities assumed based on their estimated fair values on the date of the acquisition. We identified that the acquired assets were assigned a fair value of $695 million. The majority of these assets were property, plant and equipment valued using the replacement cost method. This method is based on the replacement cost of comparable assets at the time of the acquisition adjusted for depreciation and economic and functional obsolescence of the asset. The Company believes the estimates are based on reasonable assumptions, but which are inherently uncertain. The remainder of the purchase price was allocated to working capital assets (primarily inventory) and goodwill. As a result, actual results may differ from the assumptions and judgments used to determine fair value of the assets acquired, which could result in material impairment losses in the future. Additional information regarding our acquisitions is included in "Note 3 - Business Acquisition" in the Notes to Consolidated Financial Statements included herein under “Item 8. Financial Statements and Supplementary Data.”

Retirement Plans and Postretirement Benefits

We have a number of defined benefit pension plans in the United States covering many of our employees. Benefit accruals under most of our defined benefit pension plans in the United States were frozen prior to January 2014.

We account for the consequences of our sponsorship of these plans using assumptions to calculate the related assets, liabilities and expenses recorded in our financial statements. Net actuarial gains and losses occur when actual experience differs from any of the assumptions used to value defined benefit plans or when assumptions change as they may each year. The primary factors contributing to actuarial gains and losses are changes in the discount rate used to value obligations as of the measurement date and the differences between expected and actual returns on pension plan assets. This accounting method results in the potential for volatile and difficult to forecast gains and losses.

We record amounts relating to these defined benefit plans based on various actuarial assumptions, including discount rates, assumed rates of return, compensation increases and life expectancy. We review our actuarial assumptions on an annual basis and make modifications to the assumptions based on current economic conditions and trends. We believe that the assumptions utilized in recording our obligations under our plans are reasonable based on our experience and on advice from our independent actuaries; however, differences in actual experience or changes in the assumptions may materially affect our financial condition or results of operations.

The following table illustrates the estimated impact on hypothetical pension obligations and expenses that would have resulted from a 25-basis point reduction in two key assumptions for the year ended December 31, 2024:

(In millions)

It is not possible to forecast or predict whether there will be actuarial gains and losses in future periods, and if required, the magnitude of any such adjustment. These gains and losses are driven by differences in actual experience or changes in the assumptions that are beyond our control, such as changes in interest rates and the actual return on pension plan assets.

Non-GAAP Financial Measures

In evaluating our business, we utilize several non-GAAP financial measures. A non-GAAP financial measure is generally defined by the SEC as one that purports to measure historical or future financial performance, financial position or cash flows, but excludes or includes amounts that would not be so excluded or included under applicable GAAP guidance. In this report on Form 10-K, we disclose income (loss) from operations before interest expense, net, non-operating pension and other post employment benefit costs, income tax expense, depreciation and amortization, other operating charges, net, and debt retirement costs as Adjusted EBITDA from continuing operations which is a non-GAAP financial measure. Adjusted EBITDA from continuing operations is not a substitute for the GAAP measure of net income or for any other GAAP measures of operating performance.

We have included Adjusted EBITDA from continuing operations in this report because we use it as an important supplemental measure of our performance and believe that it is frequently used by securities analysts, investors and other interested persons in the evaluation of companies in our industry, some of which present Adjusted EBITDA when reporting their results. We use Adjusted EBITDA from continuing operations to evaluate our performance as compared to other companies in our industry that have different financing and capital structures and/or tax rates. It should be noted that companies calculate Adjusted EBITDA differently and, therefore, our Adjusted EBITDA from continuing operations measure may not be comparable to Adjusted EBITDA reported by other companies. Our Adjusted EBITDA from continuing operations measure has material limitations as a performance measure because it excludes interest expense, net, income tax (benefit) expense and depreciation and amortization which are necessary to operate our business or which we otherwise incur or experience in connection with the operation of our business. In addition, we exclude other income and expense items which are outside of our core operations.

The following table provides our Adjusted EBITDA from continuing operations for the periods presented and a reconciliation to net income.

OPERATING RESULTS FROM CONTINUING OPERATIONS

The financial information below reflects reclassifications from previously reported information based upon discontinued operations. Historically, the Company has shown certain intercompany pulp costs as offsets as they represent intercompany transactions between our tissue business and the pulp and paperboard manufacturing operations. Based upon discontinued operations treatment, such transfers of pulp and other inputs have been recast to Net Sales on the Consolidated Statements of Operations.

(1) See Note 10, "Other operating charges," of the Notes to the Consolidated Financial Statements included in Item 8 of this report for additional information.

Net Sales

Net sales increased 21.8% for the year ended December 31, 2024 compared to December 31, 2023 due the inclusion of the Augusta operations (see Note 3, "Business Acquisition" of the Notes to the Consolidated Financial Statements included in Item 8 of this report for additional information). This increase was driven by higher sales volume offset by decreases in sales prices due to previously announced price decreases and changes in our product mix.

Net sales decreased 4.9% for the year ended December 31, 2023 compared to December 31, 2022 due to weaker demand as customers rebalanced inventory levels. Pulp sales volumes increased for the year ended December 31, 2023 as we managed our paperboard production resulting in additional pulp to be sold.

Cost of sales

Costs included in our cost of sales include input costs (principally raw materials and energy), labor and overhead, supply chain costs (principally freight and outside warehousing). The table below provides the details of our cost of sales for the years ended December 31, 2024, 2023 and 2022.

Cost of sales increased 39.8% for the year ended December 31, 2024 compared to the year ended December 31, 2023 due to the inclusion of the Augusta operations. Input costs increased due to higher sales volume with reductions on a per ton basis across fiber, energy and chemicals due to deflation. Our labor and overhead increased due to the inclusion of the Augusta operation as well as planned annual maintenance at both our Lewiston, Idaho and our Augusta, Georgia facilities. Depreciation increased due to the inclusion of the Augusta operations. Supply chain cost increased due to higher volumes offset by lower freight costs per ton due to deflation.

Cost of sales decreased 4.8% from the year ended December 31, 2023 compared to the year ended December 31, 2022 due to lower volumes offset by higher inflation. Input costs on a per ton basis increased due to higher fiber and chemical costs on a per ton basis offset by lower energy costs. Our labor and overhead increased due to inflation. Supply chain cost decreased due to lower volumes offset by lower freight costs per ton due to deflation.

Gross profit

Gross profit declined 62.1% for the year ended December 31, 2024 compared to the year ended December 31, 2023 due to previously announced price decreases and higher costs due to our planned major maintenance outage at our Lewiston, Idaho and Augusta, Georgia facilities offset by lower input costs due to deflation.

Gross profit declined 5.6% for the year ended December 31, 2023 compared to the year ended December 31, 2022 due to reduced sales volumes and planned production downtime to manage inventory partially offset by deflation in input and supply chain costs.

Selling, general and administrative

Selling, general and administrative expenses decreased 2.3% for the year ended December 31, 2024 compared to the year ended December 31, 2023 primarily as a result of lower incentive pay due to lower operational performance partially offset by higher wages and benefits related to additional sales costs associated with the Augusta acquisition.

Selling, general and administrative expenses increased 8.5% for the year ended December 31, 2023 compared the year ended December 31, 2022 primarily related to costs associated with business improvement projects including information technology and other projects and higher wages partially offset by lower incentives due to lower operating performance.

Other operating charges

See Note 10, "Other Operating Charges, net" of the Notes to the Consolidated Financial Statements included in Item 8 of this report for additional information.

Overall income from continuing operations and Adjusted EBITDA

Operating income from continuing operations and Adjusted EBITDA from continuing operations decreased for the year ended December 31, 2024 as compared to the year ended December 31, 2023 due to lower sale prices and planned major maintenance at both our Lewiston and Augusta facilities partially offset by higher volume. Additionally, impacting operating income from continuing operations were the transaction and integration cost associated with the acquisition of the Augusta facility.

Operating income from continuing operations and Adjusted EBITDA from continuing operations decreased for the year ended December 31, 2023 as compared to the year ended December 31, 2022 due to lower sales volume and planned production downtime to manage inventory and increase costs associated with business improvement projects.

OPERATING RESULTS FROM DISCONTINUED OPERATIONS

For the year ended December 31, 2024 as compared to the year ended December 31, 2023, retail sales volume declined due to the sale of our tissue business on November 1, 2024. Retail sales prices decreased due to changes in our product mix and reductions resulting from contract pricing indexed to certain cost inputs. Operating income decreased predominately due to lower sales prices offset by lower input costs, primarily in pulp, freight and energy costs.

For the year ended December 31, 2023 as compared to the year ended December 31, 2022, retail sales volumes in our tissue business increased due to the increased demand for private label versus branded products. Retail sales prices increased in our tissue business due to previously announced price increases and improved product mix. Operating income increased due to higher volumes and pricing and lower freight costs.

POTENTIAL IMPAIRMENTS

We review from time-to-time possible dispositions or reorganization of various assets in light of current and anticipated

economic and industry conditions, our strategic plan and other relevant factors. Because a determination to dispose or reorganize particular assets may require management to make assumptions regarding the transaction structure of the disposition or reorganization and to estimate the net sales proceeds, which may be less than previous estimates of undiscounted future net cash flows, we may be required to record impairment charges in connection with decisions to dispose of assets.

2025 OPERATIONS

For 2025, we expect a continued improvement in demand for SBS paperboard products. Various industry publications suggest demand will return to pre-COVID levels by the end of 2025. We expect this increase in demand will be offset by additional market capacity expected to come online at the beginning in the second quarter of 2025. SBS is currently in a downcycle, which we believe to be a temporary condition until supply and demand come back into balance. As we navigate the current environment, we are focused on actions that are in our control, including improving our operational performance, reducing cost, and strengthening our product offering. We are taking actions to reduce our cost structure and are targeting $30 to $40 million in cost savings in 2025 across selling, general and administrative and operations. We continue to explore ways to broaden our product offering to better service our converter customers. Near-term initiatives include compostability, increasing the recycled content of our products, and lightweighting. Over the longer term, we are also exploring options to diversify into other substrates that may include beverage carrier grades, white top, or recycled board. We remain confident in the long term fundamentals of the paperboard market and our ability to deliver strong margins and cash flows through the cycle.

LIQUIDITY AND CAPITAL RESOURCES

Overview

Our principal sources of liquidity are existing cash, cash generated by our operations and our ability to borrow under such credit facilities as we may have in effect from time to time. At times, we may also issue equity, debt or hybrid securities or engage in other capital market transactions. Due to the competitive and cyclical nature of the markets in which we operate, there is uncertainty regarding the amount of cash flows we will generate during the next twelve months. However, we believe that our cash flows from operations, our cash on hand and our borrowing capacity under our Credit Agreements will be adequate to fund debt service requirements and provide cash to support our ongoing operations, capital expenditures and working capital needs for the next twelve months.

Our principal uses of liquidity are paying the costs and expenses associated with our operations, servicing outstanding indebtedness and making capital expenditures. We may also from time to time prepay or repurchase outstanding indebtedness or shares or acquire assets or businesses that are complementary to our operations. Any such prepayments, repurchases or acquisitions may be commenced, suspended, discontinued, or resumed, and the method or methods of effecting any such prepayments or repurchases may be changed at any time or from time to time without prior notice.

Operating Activities

During 2024, we generated $61.4 million of cash from operations, as compared to $190.7 million in 2023. This decrease was driven by lower operating performance and changes in working capital. Accounts receivable and accounts payable agings have remained relatively consistent with balances as of December 31, 2023.

During 2023, we generated $190.7 million in cash from operations, as compared to $150.2 million in 2022. This increase was driven by improved operating performance and changes in working capital.

Investing Activities

During 2024, we generated $167.7 million in cash from investing activities, as compared to a use of $73.7 million in 2023. This includes a use of $708.2 million for the acquisition of the Augusta operations and business and net proceeds of $992.5 million received from the divestiture of our tissue business. Included in accounts payable and accrued liabilities was $25.8 million related to capital expenditures that had not yet been paid at December 31, 2024.

During 2023 we used $73.7 million in cash for investing activities, as compared to $33.5 million in cash for investing activities in 2022. In both years, cash used for investing activities was related to capital expenditures. Included in accounts payable and accrued liabilities was $13.0 million related to capital expenditures that had not yet been paid at December 31, 2023.

In 2025, we expect cash paid for capital expenditures to be approximately $80 million to $90 million.

Financing Activities

Net cash flows used in financing activities were $191.4 million for 2024. We received net proceeds of $753.4 million from the issuance of long-term debt related to the Augusta acquisition and to cover short term cash requirements. We repaid $931.1 million of long-term debt. Additionally, we used $5.6 million for debt issuance costs and $10.0 million to repurchase stock under our stock repurchase program during the year ended December 31, 2024.

Net cash flows used in financing activities were $129.4 million for 2023 as compared to $88.6 million for 2022. The

increase was due to higher debt repayments in 2023 driven by improved operating results which provided additional available cash to fund debt repayments. Additionally, we used $17.9 million for common stock repurchases under our stock repurchase program during the year ended December 31, 2023.

Commitments

As of December 31, 2024, we have purchase commitments of $102.6 million, of which $53.4 million is payable within 12 months, related to contracts with natural gas and electricity providers, contracts for the purchase of chemicals and pulp, and contracts associated with IT services that are legally binding on us and specify fixed or minimum quantities. Additionally, we have $35.6 million, all of which is payable within 12 months, in purchase commitments associated with capital expenditures.

Credit Agreements

We are party to an amended and restated credit agreement (which may be amended from time to time, the “PCA Credit Agreement”) that consists of a term revolver commitment in the amount of $270 million. We may also increase term revolver commitments under the PCA Credit Agreement in an aggregate amount of up to $60 million, subject to obtaining commitments from any participating lenders and certain other conditions. The obligations under the PCA Credit Agreement are secured by liens on substantially all of our personal property assets and each of our domestic subsidiaries that are guarantors of the PCA Credit Agreement. Borrowings under the PCA Credit Agreement are subject to mandatory prepayment in certain circumstances. We may, at our option, prepay and reborrow any borrowings under the PCA Credit Agreement, in whole or in part, at any time and from time to time without premium or penalty (except in certain circumstances). The PCA Credit Agreement matures on May 1, 2029, subject to a springing maturity beginning on the date that is 91 days prior to the maturity of the Company’s 2020 Notes if the outstanding principal amount of the 2020 Notes plus $50 million is at any time during such 91 day period great than the sum of our available borrowing liquidity and unrestricted cash.

We are also party to an asset-based loan credit agreement (which may be amended from time to time, the “ABL Credit Agreement,” and together with the PCA Credit Agreement, the “Credit Agreements”)) that consists of a $375 million revolving loan commitment, subject to borrowing base limitations. Borrowings under the ABL Credit Agreement are subject to mandatory prepayment in certain circumstances. We may also increase the revolving commitments under the ABL Credit Agreement in an aggregate amount of up to $100 million, subject to obtaining commitments from any participating lenders and certain other conditions. The obligations under the ABL Credit Agreement are secured by liens on substantially all of our personal property assets and each of our domestic subsidiaries that are guarantors of the ABL Credit Agreement. We may, at our option, prepay and reborrow any borrowings under the ABL Credit Agreement, in whole or in part, at any time and from time to time without premium or penalty (except in certain circumstances). The ABL Credit Agreement matures on November 7, 2027. As of December 31, 2024, we had no outstanding borrowings under this facility and $3.7 million drawn to support our letters of credit.

Both Credit Agreements contain customary representations, warranties, and affirmative and negative covenants. The

ABL Credit Agreement also contains a financial covenant, which requires us to maintain a consolidated fixed charge coverage ratio of not less than 1.10x to 1.00x, provided that the financial covenant under the ABL Credit Agreement is only applicable during an event of default or if availability, as calculated under the ABL Credit Agreement, is at any time less than or equal to the greater of (i) 10.0% the Line Cap (as defined above) and (ii) $25 million.

At December 31, 2024, we were in compliance with the covenants in the Credit Agreements, and based on our current financial projections, we expect to remain in compliance. However, if our financial position, results of operations or market conditions deteriorate, we may not be able to remain in compliance. There can be no assurance that we will be able to remain in compliance with the Credit Agreements. See Note 9, "Debt," to the Notes to Consolidated Financial Statements included in Item 8 of this report for additional information.

Interest Rate Risk

Our exposure to market risk on financial instruments is limited to our Credit Agreements. As of December 31, 2024, there were no borrowings outstanding under our Credit Agreements. The interest rates applied to borrowings on both Credit Agreements are adjusted often and therefore react quickly to any movement in the general trend of market interest rates.

Foreign Currency Risk

We have minimal foreign currency exchange risk. Nearly all of our international sales are denominated in U.S. dollars.

Evaluation of disclosure controls and procedures

We maintain “disclosure controls and procedures,” as such term is defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, or the Exchange Act, that are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer, or CEO, and Chief Financial Officer, or CFO, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognized that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Additionally, in designing disclosure controls and procedures, our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of disclosure controls and procedures is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Subject to the limitations noted above, our management, with the participation of our CEO and CFO, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the fiscal year covered by this annual report on Form 10-K. Based on that evaluation, the CEO and CFO have concluded that, as of such date, our disclosure controls and procedures are effective to meet the objective for which they were designed and operate at the reasonable assurance level.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f). Under the supervision and with the participation of our management, including our CEO and CFO and with the oversight of the Audit Committee of the Board of Directors, our management conducted an assessment of the effectiveness of our internal control over financial reporting based on the framework in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework). Based on our evaluation under the 2013 Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2024.

The effectiveness of our internal control over financial reporting as of December 31, 2024 has been audited by KPMG LLP, an independent registered public accounting firm, as stated in their report included in this Annual Report on Form 10-K.

The financial controls for Augusta Pulp and Paperboard operations (acquired in May 2024) were eligible for a one-year exemption from the requirements of Section 404 and had been excluded from this report as of December 31, 2024. There was no exemption available for internal controls over financial reporting of the Company’s processes and systems as they relate to our oversight and consolidation of the Augusta Pulp and Paperboard operations into the consolidated financial results. The purchase of the Augusta operation represents 42% of our total assets as reported on the December 31, 2024 Consolidated Balance Sheet and 25% of our Net sales as reported on our Consolidated Statement of Operations for the year ended December 31, 2024.

Changes in internal control over financial reporting

There were no changes in our internal control over financial reporting that occurred during our most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors

Clearwater Paper Corporation:

Opinion on Internal Control Over Financial Reporting

We have audited Clearwater Paper Corporation and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2024 and 2023, the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2024, and the related notes (collectively, the consolidated financial statements), and our report dated February 24, 2025 expressed an unqualified opinion on those consolidated financial statements.

The Company acquired Augusta Mill during 2024, and management excluded from its assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2024, Augusta Mill’s internal control over financial reporting associated with 42% of total assets and 25% Net sales included in the consolidated financial statements of the Company as of and for the year ended December 31, 2024. Our audit of internal control over financial reporting of the Company also excluded an evaluation of the internal control over financial reporting of Augusta Mill.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
