LPX Louisiana-Pacific Corp - 10-K

ITEM 1A.     Risk Factors

You should be aware that the occurrence of any of the events described in this Risk Factors section and elsewhere in this annual report on Form 10-K or in any other of our filings with the SEC could have a material adverse effect on our business, financial position, results of operations and cash flows. In evaluating us, you should consider carefully, among other things, the risks described below and the matters described in “Cautionary Statement Regarding Forward-Looking Statements.”

BUSINESS AND OPERATIONAL RISK FACTORS

Unplanned events may interrupt our manufacturing operations, which may adversely affect our business. The manufacturing of our products is subject to unplanned events such as explosions, fires, inclement weather, natural disasters, accidents, equipment failures, or labor disruptions that may be caused by, among other factors, changes in immigration policy, transportation interruptions, supply interruptions, public health issues (including pandemics and quarantines), riots, civil insurrection or social unrest, looting, protests, strikes, and street demonstrations. During the year ended December 31, 2025, fire interruptions reduced production by less than 1%, but future fire or other operational interruptions could significantly curtail the production capacity of a facility for a period of time. We have redundant capacity and capability to produce many of our products within our manufacturing platform to mitigate our business risk from such interruptions, but major or prolonged interruptions could compromise our ability to meet our customers’ needs. Delayed delivery of our products to customers who require on-time delivery from us may cause customers to purchase alternative products at a higher cost, reschedule their own production, or incur other incremental costs. Customers may be able to pursue financial claims against us for their incremental costs, and we may incur costs to correct such problems in addition to any liability resulting from such claims. Interruptions may also harm our reputation among actual and potential customers, potentially resulting in a loss of business. To the extent these losses are not covered by insurance, our financial position, results of operations, and cash flows could be adversely affected by such events.

We mostly depend on third parties for transportation services and increases in costs or changes in the availability of transportation could materially and adversely affect our business and operations. Our business depends on the transportation of many products, both domestically and internationally. We rely primarily on third parties for transportation of the products we manufacture and/or distribute as well as for delivery of our raw materials. In particular, a significant portion of the goods we manufacture and raw materials we use are transported by railroad or trucks, which are highly regulated. There may be labor unrest or disputes, including strikes and work stoppages, among workers at various transportation providers and in industries affecting the transportation industry, including those that are unionized, like the railroad industry. If any of our third-party transportation providers were to fail to deliver the goods we manufacture or distribute in a timely manner, or fail to deliver raw materials to us in a timely manner, it could impact our ability to manufacture and deliver our products, or to sell those products at full value or at all. In addition, if any of these third parties were to cease operations or cease doing business with us, we may be unable to replace them at a reasonable cost. Any failure of a third-party transportation provider to deliver raw materials or finished products in a timely manner could harm our reputation, impact our ability to manufacture and deliver our products, negatively affect our customer relationships and have a material adverse effect on our financial condition and results of operations. Further, an increase in transportation rates and oil and/or fuel surcharges could materially and adversely affect financial results, including profitability.

Our reliance on third-party wholesale distribution channels could impact our business. We offer our products directly and through a variety of third-party wholesale distributors and dealers. Adverse changes in the financial or business condition of these wholesale distributors and dealers or our customers, including as a result of the impacts arising from tariffs, geopolitical conflicts, supply chain disruptions, or inflation, could subject us to losses and affect our ability to bring our products to market. One or more of our customers may experience financial difficulty, file for bankruptcy protection, or go out of business as a result of general market conditions or various other events, which could result in an increase in customer financial difficulties that affect us. The direct impact on us could include reduced revenues and write-offs of accounts receivable and could negatively impact our cash flow. While we currently cannot estimate what those effects will be, if they are severe, the indirect impact could include impairments of intangible assets and reduced liquidity, among others. Any such adverse changes could have a material adverse effect on our business, financial position, liquidity, results of operations, and cash flows. Further, our ability to effectively manage inventory levels at wholesale distributor locations may be impaired as a result of adverse changes in the financial or business condition of such wholesale distributors, which could increase expenses associated with excess and obsolete inventory and negatively impact our cash flows.

We may experience difficulties in the development, launch or production ramp-up of new products, which could adversely affect our business. Our continued success depends in part on our ability to develop new products that will meet the demands of our customers. We may not be successful in developing new products on an effective and financially profitable basis. Additionally, as we ramp up manufacturing processes for newly introduced products, we may experience difficulties, including manufacturing disruptions, delays, or other complications, which could adversely impact our ability to serve our customers, our reputation, our costs of production, and, ultimately, our financial position, results of operations and cash flows.

We may be unable to attract and retain qualified executives, management and other key employees. Our success depends in part on our ability to attract and retain employees with the skills necessary to operate and maintain our facilities, produce our products, and serve our customers. Our key executives and management employees are important to our business and could be difficult to replace because they have extensive experience and skills relevant to our industry and business operations. In addition, the competition for skilled manufacturing, engineering, sales and other personnel, both hourly and salaried, may be intense in the regions where we operate. Our failure to hire and retain employees capable of performing at a high level, to successfully implement succession plans for executives and management employees, or to implement effective training plans for new personnel could jeopardize our ability to grow our business and could adversely impact our financial position, results of operations and cash flows.

Cybersecurity risks related to the technology used in our operations and other business processes, as well as security breaches of Company, customer, consumer, employee, or vendor information, could adversely affect our business. We rely on various information technology systems to capture, process, store, and report data and interact with customers, consumers, employees, and vendors. Despite careful security and controls design, implementation, updating, and internal and independent third-party assessments, our information technology systems, and those of our third-party providers, could become subject to security breaches, cyber-attacks, ransomware attacks, employee misconduct, computer viruses, unauthorized access attempts, phishing, social engineering, misplaced or lost data, programming and/or human errors or other similar events. Network, system, and data breaches could result in misappropriation of trade secrets or sensitive data or operational disruptions, including interruption to systems availability and denial of access to, and misuse of, applications required by our customers and vendors to conduct business with us. In addition, hardware and operating system software and applications that we procure from third parties may contain defects in design or manufacture, including “bugs” and other problems that could unexpectedly interfere with the operation of the systems. Misuse of internal applications, theft of intellectual property, trade secrets, or other corporate assets, and inappropriate disclosure of confidential information could stem from such incidents. A cybersecurity breach could result in manipulation and destruction of sensitive data, cause critical systems to malfunction, be damaged or shut down, and lead to disruption to our operations and production downtimes, potentially for lengthy periods. Theft of personal or other confidential data and sensitive proprietary information could also occur as a result of a cybersecurity breach, exposing us to costs and liabilities associated with privacy and data security laws in the jurisdictions in which we operate.

While we have security measures in place that are designed to protect customer and other sensitive information and the integrity of our information technology systems and prevent data loss and other security breaches, our security measures or those of our third-party service providers may not be sufficiently broad in scope to protect all relevant information, may not function as planned, or may be breached as a result of third-party action, employee or vendor error, malfeasance, or otherwise. While we maintain cybersecurity insurance, the costs related to cybersecurity threats or disruptions may not be fully insured. Because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently or may be designed to remain dormant until a predetermined triggering event and often are not recognized until launched against a target, we may be unable to anticipate these techniques or implement sufficient control measures to defend against these techniques. The rapid evolution and increased adoption of generative artificial intelligence (AI) is further increasing risks in this area, including by making cyberattacks more difficult to detect, contain or mitigate and making fraud detection more difficult, particularly with detection devices that use voice recognition or authentication. Once a security incident is identified, we may be unable to fully remediate or otherwise respond to such an incident in a timely manner, which may cause us to incur remediation or other costs or subject us to demands to pay a ransom fee. Additionally, a breach could expose us and our customers, consumers, vendors, and employees to risks of misuse of such information. Such negative consequences of cyberattacks, cybersecurity failures or other security breaches could impact our ability to operate our businesses effectively, adversely affect our reputation, competitive position, business or financial results, and expose us to potential liability, litigation, governmental inquiries, investigations or regulatory enforcement actions. In addition, the lost profits and increased costs related to cybersecurity or other security threats or disruptions may not be fully insured against or indemnified by other means. As a result, cybersecurity and the continued development and enhancement of our controls, processes, and practices remain a priority for us. We may be required to expend additional resources to continue to enhance our security measures necessary to investigate and remediate any security vulnerabilities. We cannot predict the degree of any impact that increased monitoring, assessing, or reporting of cybersecurity matters would have on operations, financial conditions and results.

From time to time, we may implement new technology systems or replace and/or upgrade our current information technology systems. These upgrades or replacements may not improve our productivity to the levels anticipated and may subject us to inherent costs and risks associated with implementing, replacing, and updating these systems, including potential disruption of our internal control structure, substantial capital expenditures, demands on management time and other risks of delays or difficulties in transitioning to new systems or of integrating new systems into other existing systems. Our development, integration and use of AI technology in our operations remains in the early phases. Although we aim to implement AI technology according to responsible procedures and adequate safeguards, our current or future use of AI or machine learning tools in our business operations could expose us to new or additional costs and risks, including the potential introduction of new vulnerabilities or cybersecurity risks within our information technology systems; the potential inadvertent or unauthorized release of our confidential or proprietary information resulting from the use (whether or not authorized) of AI or machine learning tools by our employees, contractors, agents, representatives, vendors or customers; the potential loss of our intellectual property or our potential infringement of the intellectual property rights of third parties resulting from the use (whether or not authorized) of AI or machine learning tools in our operations; and potential legal or reputational harms due to insufficient or flawed data, inaccurate or misleading outputs, insufficient quality control, or unlawful bias or discrimination associated with the use of AI or machine learning tools. In addition, the AI tools we may incorporate into certain aspects of our operations may not generate the intended efficiencies and may impact our business results. Our inability to prevent information technology system disruptions or to mitigate the impact of such disruptions could have an adverse effect on our business.

Because our intellectual property and other proprietary information may become compromised, we are subject to the risk that competitors could copy our products or processes. Our success depends, in part, on the proprietary nature of our technology, including non-patentable intellectual property, such as our process technology. To the extent that a competitor can reproduce or otherwise capitalize on our technology, it may be difficult, expensive, or impossible for us to obtain adequate legal remedies or other recourse. Also, the laws of some foreign countries may not protect our intellectual property to the same extent as do the laws of the United States. In addition to patent protection of intellectual property rights, we consider elements of our product designs and processes to be proprietary and confidential, and/or trade secrets. To safeguard our confidential information, we rely on employee, consultant, and vendor nondisclosure agreements and contractual provisions and a system of internal and technical safeguards. However, any of our registered or unregistered intellectual property rights may be subject to challenge or possibly exploited by our competitors or other third parties, which could materially adversely affect our financial position, results of operations, cash flows, and competitive position.

We manufacture and distribute our products in jurisdictions outside the United States and are exposed to risks associated with international business operations, including risks related to potential supply chain disruptions, such as delays, cost fluctuations, and challenges in sourcing materials or components due to geopolitical events, government trade policies, or logistical constraints. We manufacture our products in the United States, Canada, Chile, and Brazil and sell our products primarily in North America and South America. We operate a supply chain that involves the shipment of goods from certain international markets to the jurisdictions where we manufacture our products. Accordingly, we are subject to risks associated with potential disruption caused by changes in political, monetary, economic, and social environments, including civil and political unrest, terrorism, possible expropriation, local labor conditions (including labor disruptions or shortages), changes in laws, regulations, and policies of foreign governments and trade disputes with the United States (including tariffs), and compliance with U.S. laws affecting activities of U.S. companies abroad, including tax laws, economic sanctions and enforcement of contract and intellectual property rights. Steps taken by the U.S. government to apply new, or increase existing, tariffs on certain products and materials imported into the U.S. could potentially disrupt our existing supply chains and have imposed, and could continue to impose, additional costs on our business, including costs with respect to raw materials upon which our business depends. Additionally, potential tariffs imposed by other countries in response to U.S. trade policies could adversely affect our ability to export products from the United States to key international markets, leading to decreased sales and profitability. Such retaliatory tariffs could also increase the cost of certain components and materials that we import into the U.S., further straining our supply chain and impacting our overall financial performance.

Our international operations and sourcing of materials could be harmed by a variety of factors, including:

• recessionary trends in international markets;

• legal and regulatory changes and the burdens and costs of our compliance with a variety of laws, including but not limited to export controls, import and customs trade restrictions, tariffs, and regulations related to public health matters;

• increases in transportation costs or transportation delays;

• work stoppages, unionization efforts and labor strikes;

• fluctuations in currency exchange rates, particularly the value of the U.S. dollar relative to other currencies; and

• social and political unrest, geopolitical and military conflicts or tensions, terrorism and economic instability.

If any of these or other factors were to render the conduct of our business in a particular country undesirable or impractical, our business, financial condition, or results of operations could be materially adversely affected.

In 2025, the U.S. government announced significant changes to U.S. trade policy, including the implementation or planned imposition of new or increased tariffs and trade barriers on a broad range of goods imported from international markets, as well as the potential modification or termination of existing trade agreements between the U.S. and certain other countries. In response, certain countries have imposed, or are considering, retaliatory tariffs on U.S. exports. Changing trade policy in the U.S. and other countries could continue to increase the cost of certain raw materials or components that are critical to our manufacturing process, which could have a material negative impact on our manufacturing costs and our overall financial performance. For the year ended December 31, 2025, we incurred $8 million in expenses related to new or increased tariffs. While we do not consider the impact on our 2025 financial results to be material, and impact from increased tariffs are not currently expected to be material in 2026, given the rapid changes and growing uncertainty relating to the global tariff landscape, the potential impact of these factors on our future operational and financial performance is uncertain and our sales and our competitive position within the U.S. market and in markets outside the U.S. could be negatively impacted.

We may pursue acquisitions, divestitures, joint ventures, capital investments and other corporate strategic transactions from time to time. These transactions may involve risks or may not be successful. Our business strategy may depend, in part, on our ability to accomplish successful acquisitions, divestitures, joint ventures, capital investments and other corporate strategic transactions that we may pursue. The benefits we typically expect to achieve from such corporate strategic transactions may include, among other things, synergies, cost savings, growth opportunities and access to new markets, and in the case of divestitures, the disposition of businesses or assets that do not align with our long-term strategy and the realization of proceeds from the sale of businesses and assets to unrelated purchasers. We are subject to the risk that we may not achieve the expected benefits associated with such transactions. Failure to achieve such benefits could have a material adverse impact on our financial position, operating results and cash flows .

Additionally, corporate strategic transactions that we may pursue may involve a number of special risks, including, among other things, the diversion of management attention and business resources in connection with the pursuit of such transactions and the integration of acquired assets or businesses into our operations, the demands on our financial, operational and information technology systems resulting from the acquisition of assets or businesses, and the possibility that we may become responsible for unexpected liabilities resulting from an acquisition for which we may not be adequately indemnified. These and other risks associated with corporate strategic transactions we may pursue may be unpredictable and beyond our control and could have a material adverse impact on our financial position, reputation, operating results and cash flows.

The impact of new ongoing or escalated military and geopolitical conflicts and tensions on the global economy, energy supplies and raw materials may prove to negatively impact our business and operations. Our business could be negatively affected by the impact of new or ongoing military or geopolitical conflicts on international markets and the global economy. The impact of ongoing conflicts and/or escalation thereof could include increased volatility in financial and commodity markets, increased energy prices, increased maritime shipping costs, supply chain disruptions, a higher level of general market and macroeconomic instability, increased cyber attacks and violent protests or political or social unrest in areas outside the immediate conflict area, among other things. These conflicts and tensions and other military or geopolitical conflicts or tensions that may arise in the future could materially adversely affect our operations, financial position, and results.

We are subject to physical, operational, transitional, and financial risks associated with climate change and global, regional, and local weather conditions, and with legal, regulatory, and market responses to climate change. There has been an evolving focus, including from investors, the general public, and U.S. and foreign governmental and nongovernmental authorities, regarding sustainability matters, including with respect to climate change, greenhouse gas emissions, packaging and waste, sustainable supply chain practices, deforestation, and land, energy, and water use. We cannot predict whether our disclosures or performance will be considered satisfactory or the extent to which a change in monitoring, assessing, or reporting of sustainability may impact our operations, financing condition, and results.

The unpredictability and frequency of natural disasters such as hurricanes, earthquakes, hailstorms, wildfires, snow, ice storms, the spread of disease, and insect infestations could affect the supply of raw materials or cause variations in their costs, or variations in transportation-related costs. In addition, global climate change may increase the frequency or intensity of extreme weather events, such as storms, floods, heat waves, and other events that could affect our facilities and demand for our products.

Our suppliers and the third parties we rely on for transportation may also be impacted by evolving sustainability reporting requirements or risks associated with the transition to a lower carbon economy, which may adversely impact their ability to provide us with goods and services and we may be unable to meet consumer demands at the same cost or in a timely fashion.

Our reputation may be adversely affected if we are not able to achieve our sustainability and corporate responsibility priorities or otherwise meet the expectations of our stakeholders with respect to these matters. We strive to deliver shared value through our business. From time to time, we announce certain aspirations and priorities relevant to these matters and publish information about our sustainability and corporate responsibility priorities, strategies, and progress on our corporate website, our sustainability report and in public filings (none of which are incorporated by reference into and do not form any part of this annual report on Form 10-K or our other filings with the SEC unless expressly incorporated by reference). Achievement of these priorities and strategies is subject to risks and uncertainties, many of which are outside of our control, and it is possible that we may not achieve all our priorities or certain of our stakeholders might not be satisfied with our efforts regarding these matters. Perceived failures or delays in meeting our sustainability and corporate responsibility priorities could adversely affect public perception of our business, employee morale or customer or stakeholder support, and may negatively impact our financial condition and results of operations.

Stakeholder expectations regarding sustainability practices are diverse, rapidly changing, and may impact reporting requirements, voluntary disclosures, and the setting of goals and commitments. Developing, sharing and acting on sustainability initiatives, and collecting, measuring, and reporting related data, can be costly, difficult, and time-consuming. Any failure or perceived failure by us in this regard could adversely impact our business and reputation.

INDUSTRY RISK FACTORS

Our business primarily relies on North American new home construction and repair and remodeling, which are impacted by risks associated with fluctuations in the housing market. Downward changes in the general economy, the housing market, or other business conditions could adversely affect our results of operations, cash flows, and financial condition. The housing market is sensitive to changes in economic conditions and other factors, such as the level of employment, access to labor, consumer confidence, consumer income, availability of financing, prevailing interest rates and the cost of home mortgage financing, inflation levels, and growth of the gross domestic products in the countries in which we operate.

Adverse changes in any of these conditions generally, or in any of the markets where we operate, could decrease demand for our products and could adversely impact our businesses by: causing consumers to delay or decrease homeownership or relocation; making consumers more price-conscious, resulting in a shift in demand to smaller or less expensive homes; making consumers more reluctant to make investments in their existing homes; or making it more challenging to secure loans for major renovations or new home construction. Unfavorable changes in demographics, credit markets, consumer confidence, household incomes, inflation, housing affordability, or housing inventory levels and occupancy rates, or a weakening of the U.S. economy or of any regional or local economy in which we operate, could adversely affect consumer spending, result in decreased demand for our products, and adversely affect our business. If conditions in the overall housing market or in a specific market or submarket worsen in the future beyond our current expectations, such changes could continue to have a material adverse effect on our financial position, results of operations, and cash flows. Additionally, higher interest rates, higher levels of unemployment, restrictive lending practices, heightened regulation, and increased foreclosures could have a material adverse effect on our financial position, results of operations, and cash flows.

We have a high degree of product concentration in OSB, which is subject to commodity pricing and associated price volatility. OSB accounted for about 33% of our North American net sales in 2025 and 43% in each of 2024 and 2023. We expect OSB sales to continue to account for a substantial portion of our revenues and profits in the future. The concentration of our business in the OSB market increases our sensitivity to commodity pricing and price volatility. Historical prices for our commodity products have been volatile, and we, like other participants in the building products industry, have limited influence over the timing and extent of price changes for our commodity products. Commodity product pricing is significantly affected by the relationship between supply and demand in the building products industry. Product supply is influenced primarily by fluctuations in available manufacturing capacity. Demand is affected by the state of the economy in general and a variety of other factors, including the level of new residential construction activity, home repair and remodeling activity, and changes in the availability and cost of mortgage financing. In this competitive environment, with many variables beyond our control, we cannot guarantee that pricing for our OSB products will not decline from current levels. Decreases in pricing for OSB products may have a material adverse effect on our financial position, liquidity, results of operations, and cash flows. The continued development of builder and consumer preference for our OSB products (commodity and LP ® Structural Solutions) over competitive products is critical to sustaining and expanding demand for our products. Therefore, a failure to maintain and increase builder and consumer acceptance of our OSB products could also have a material adverse effect on our financial position, liquidity, results of operations, and cash flows.

Intense competition in the building products industry could prevent us from increasing or sustaining our net sales and profitability. The markets for our products are highly competitive. Our competitors range from very large, fully integrated forest and building products firms to smaller firms that may manufacture only one or a few types of products. Many of our competitors may have greater financial and other resources, greater product diversity, and better access to raw materials than we do, and certain of the mills operated by our competitors may be lower-cost producers than the mills we operate. Increased competition in any of the markets in which we operate would likely cause heightened pricing pressures in those markets. Any of these factors could have a material adverse effect on our financial position, results of operations, and cash flows.

Our results of operations may be adversely affected by potential shortages of raw materials and increases in raw material costs . We purchase various raw materials, including, among others, wood, wood-based, and resin products, which are subject to price fluctuations that could materially increase our manufacturing costs. Further, some of our suppliers have consolidated and other suppliers may do so in the future. Combined with increased demand, such consolidation could increase the price of our supplies and raw materials. The most significant raw material used in our operations is wood fiber. Wood fiber is subject to commodity pricing, which fluctuates based on market factors over which we have no control. In addition, the cost of various types of wood fiber that we purchase in the market has at times fluctuated greatly because of governmental, economic, or industry conditions and may be affected by increased demand resulting from initiatives to increase the use of biomass materials in the production of heat, power, bio-based products, and biofuels. Wood fiber supply could also be influenced by natural events, such as forest fires, ice storms, wind storms, hurricanes, and other severe weather conditions, insect epidemics, plant and tree disease, changing temperature and precipitation patterns, and other natural disasters and man-made causes, which may increase wood fiber costs, restrict access to wood fiber, or force production curtailments. In addition to wood fiber, we also use a significant quantity of various resins in our manufacturing processes. Resin product costs are influenced by changes in the prices or availability of raw materials used to produce resins, primarily petroleum products, as well as demand for and availability of resin products and their chemical precursors. OSB product prices are largely driven by the ratio of overall OSB demand to industry capacity. We are unable to determine to what extent, if any, we will be able to pass any future OSB raw material cost increases through to our customers through product price increases. Furthermore, supply disruptions in resin or wood fiber may impact our ability to produce our products or may cause production costs to increase. Our inability or unwillingness to pass increased costs through to our customers could have a material adverse effect on our financial condition, results of operations, and cash flows.

Development of Canadian provincial forest lands, from which we obtain wood fiber, can be subject to constitutionally protected Indigenous treaty, Aboriginal title, or Aboriginal rights of recognized Indigenous groups in Canada. Provincial governments are required by law to consult with Indigenous nations regarding land use development projects, including forest management plans and operations permits.

Canadian provincial governments are actively engaged in consultations or negotiations with Indigenous groups. Negotiations sometimes progress slowly and may be subject to litigation if rights-based interests are not fully addressed. In addition, it can take time for Canadian provincial governments to consult with Indigenous groups, and this too can be subject to litigation. To offset this risk, we proactively engage in efforts to share information and develop positive relationships with Indigenous communities that have cultural, spiritual, and economic interests in the areas where we operate. This focused engagement enables us to further understand and observe the rights of Indigenous groups relating to forestry activities while also minimizing risks to our business operations. Nonetheless, final or interim resolution of claims brought forward by Canadian provincial governments and Indigenous nations may result in additional restrictions on wood supply, potentially affecting our operational costs and/or timber prices over the long term.

LEGAL AND REGULATORY RISK FACTORS

We are subject to significant environmental regulation and environmental compliance expenditures and liabilities. Our business is subject to many environmental laws and regulations, particularly with respect to discharges of pollutants and other emissions on or into the land, water, and air, the disposal and remediation of hazardous substances or other contaminants, and the restoration and reforestation of timberlands. Compliance with these laws and regulations is a significant factor in our business. We have incurred and expect to continue to incur significant expenditures to comply with applicable environmental laws and regulations. Moreover, changes to the environmental laws and regulations to which we are subject and the enactment of new environmental laws, regulations, or other requirements, including with respect to greenhouse gas emissions or climate change, may cause us to incur increased and unexpected compliance costs or impose restrictions on our ability to manufacture our products or operate our business. In addition, there has historically been, and there continues to be, a lack of consistent climate legislation, which has created and continues to create economic and regulatory uncertainty. Our failure to comply with applicable environmental laws and regulations and permit requirements could result in civil or criminal fines or penalties or enforcement actions, including regulatory or judicial orders enjoining or curtailing operations or requiring corrective measures, installation of pollution control equipment, or remedial actions, as well as reputational harm.

Some environmental laws and regulations impose liability and responsibility on present and former owners, operators, or users of facilities and sites for contamination at such facilities and sites, without regard to causation or knowledge of contamination. In addition, we occasionally evaluate various alternatives with respect to our facilities, including possible dispositions or closures. Investigations undertaken in connection with these activities may lead to discoveries of contamination that must be remediated, and closures of facilities may trigger compliance requirements that are not applicable to operating facilities. Consequently, we cannot guarantee that existing or future circumstances or developments with respect to contamination will not require significant expenditures by us or have significant adverse impact on our operations.

We are subject to various environmental, product liability, and other legal proceedings, matters, and claims. The outcome of these proceedings, matters, and claims, and the magnitude of related costs and liabilities, are subject to uncertainties. We currently are, or from time to time in the future may be, involved in a number of environmental matters and legal proceedings, including legal proceedings involving antitrust, warranty or non-warranty product liability claims, negligence, and other claims, including claims for wrongful death, personal injury and property damage alleged to have arisen out of use by others of our or our predecessors’ products or the release by us or our predecessors of hazardous substances. The conduct of our business involves the use of hazardous substances and the generation of contaminants and pollutants. In addition, the end-users of many of our products are members of the general public. Environmental matters and other legal matters and proceedings, including class action settlements relating to certain of our products, have in the past caused and, in the future may cause, us to incur substantial costs. The actual or alleged existence of defects in any of our products could also subject us to significant product liability claims. We have established contingency reserves in our Consolidated Financial Statements with respect to the estimated costs of existing environmental matters and legal proceedings to the extent that our management has determined that such costs are both probable and reasonably estimable as to amount. However, such reserves are based upon various estimates and assumptions relating to future events and circumstances, all of which are subject to inherent uncertainties. We regularly monitor our estimated exposure to environmental and litigation loss contingencies and, as additional information becomes known, may change our estimates significantly. However, no estimate of the range of any such change can be made at this time. We may incur costs in respect of existing and future environmental matters and legal proceedings as to which no contingency reserves have been established. There is no assurance that we will have sufficient resources available to satisfy the related costs and expenses associated with these matters or proceedings. The incurring of costs in excess of our contingency reserves could have a material adverse effect on our business, financial condition, and results of operations.

We are subject to the U.S. Foreign Corrupt Practices Act and other anti-corruption laws, as well as other international trade and regulatory laws governing our operations. If we fail to comply with these laws, we could be subject to civil or criminal penalties, other remedial measures, and legal expenses, which could adversely affect our business, financial condition, and results of operations . Our operations are subject to anti-corruption laws, including the U.S. Foreign Corrupt Practices Act (FCPA) and other anti-corruption laws that apply in countries where we do business. The FCPA and these other laws generally prohibit us and our employees and intermediaries from bribing, being bribed or making, promising, offering or authorizing payments or gifts, with corrupt intent, to government officials or other persons to obtain or retain business or gain some other business advantage. We conduct business in a number of jurisdictions that are geographically high-risk for violations of anti-corruption laws, we participate in relationships with third parties whose actions could potentially subject us to liability under the FCPA or other anti-corruption laws, and the nature of our business involves interaction with government officials. In addition, we cannot predict the nature, scope, or effect of future regulatory requirements to which our operations might be subject or the manner in which existing laws might be administered or interpreted.

We are also subject to other laws and regulations governing our international operations, including regulations administered by the U.S. Department of Commerce’s Bureau of Industry and Security, the U.S. Department of Treasury’s Office of Foreign Assets Control, and various non-U.S. government entities, including applicable export control regulations, economic sanctions on countries, entities and other persons, customs requirements, anti-boycott regulations, currency exchange regulations and transfer pricing regulations (collectively, Trade Control Laws).

We have and maintain a compliance program with policies, procedures, and employee training to help ensure compliance with the FCPA, other applicable anti-corruption laws, and Trade Control Laws. However, despite our compliance program, there is no assurance that we or our intermediaries will be completely effective in complying with all applicable anti-corruption laws, including the FCPA or other legal requirements or Trade Control Laws. If we or our intermediaries are not in compliance with the FCPA and other anti-corruption laws or Trade Control Laws, we may be subject to criminal and civil penalties, disgorgement and other sanctions and remedial measures, and legal expenses, which could have an adverse impact on our business, financial condition, results of operations and liquidity.

Likewise, any investigation of any potential violations of the FCPA, other anti-corruption laws, or Trade Control Laws by the U.S. or foreign authorities could also have an adverse impact on our reputation, business, financial condition, and results of operations.

Regulatory and statutory changes applicable to us or our customers, including changes in tax law or effective tax rates, could adversely affect our financial condition and results of operations. We, and many of our customers, are subject to various national, state and local laws, rules, and regulations . Changes in any of these laws, rules, or regulations could result in additional compliance costs, seizures, confiscations, recalls or monetary fines, any of which could prevent or inhibit the manufacture, dis tribution and sale of our products.

We are also subject to periodic examination of our income tax returns by the Internal Revenue Service and other tax authorities. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. There can be no assurance that the outcomes from these examinations will not have a material adverse effect on our business, financial condition, and results of operations, or that our provision for income taxes will be sufficient.

We are also exposed to changes in tax laws, as well as any future regulations issued and changes in interpretations of tax laws, which can impact our current and future years' tax provisions. We monitor tax legislation changes on a global basis, including changes arising as a result of the Organization for Economic Cooperation and Development’s multi-jurisdictional plan of action to address base erosion and profit shifting, commonly referred to as the Pillar Two Inclusive Framework and the 2025 One Big Beautiful Bill Act (“The Tax Act”) with effective dates of enacted provisions ranging from 2025 through 2027. Both Pillar Two and The Tax Act are discussed further in "Note 6, Income Taxes" of the Notes to the Consolidated Financial Statements included in Item 8 of this annual report on Form 10-K. The effect of any other tax law changes or regulations and interpretations, as well as any additional tax legislation in the U.S. or other jurisdictions in which we operate, could have a material adverse effect on our business, financial condition, and results of operations.

In addition, our products and markets are subject to extensive and complex federal, local, state, and foreign statutes, ordinances, rules, and regulations. These mandates, including building design and safety and construction standards and zoning requirements, affect the cost, selection, and quality requirements of building components, such as the structural panel and siding products that we manufacture and sell, and often provide broad discretion to governmental authorities as to the types and quality specifications of products used in new home construction and repair and remodeling projects. Compliance with these standards and changes in such statutes, ordinances, rules, and regulations may increase the costs of manufacturing our products or may reduce the demand for certain of our products in the affected geographical areas or product markets. Conversely, a decrease in product safety standards could reduce demand for our more modern products if less expensive alternatives that do not meet higher standards were to become available for use in the affected geographical areas or product markets. All or any of these changes could have a material adverse effect on our business, financial condition, and results of operations.

FINANCIAL RISK FACTORS

Inflation may adversely affect us by increasing costs of raw materials, labor, and other costs beyond what we can recover through price increases. Inflation can adversely affect us by increasing the costs of raw materials and labor, and other goods or services required to operate and grow our business. Many of the markets in which we sell our products have experienced high levels of inflation in recent periods and may continue to experience high levels of inflation in the future, which may depress consumer demand for our products and reduce our profitability if we are unable to raise prices enough to keep up with increases in our costs. Inflationary pressures have resulted in increases in the cost of certain raw materials, and other supplies necessary for the production of our products, and such increases may continue to impact us in the future and expose us to risks associated with significant levels of cost inflation. If we are unable to increase our prices to offset the effects of inflation, our business, operating results, and financial condition could continue to be materially and adversely affected.

Warranty claims relating to our products and exceeding our warranty reserves could have a material adverse effect on our business. We have offered, and continue to offer, various warranties on our products. Although we maintain reserves for warranty-related claims and we have established and recorded product-related warranty reserves on our Consolidated Financial Statements, we cannot guarantee that warranty expense levels or the results of any warranty-related legal proceedings will not exceed our reserves. If our warranty reserves are significantly exceeded, the costs associated with such warranties could have a material adverse effect on our financial position, results of operations, and cash flows.

We have not independently verified the results of third-party research or confirmed assumptions or judgments upon which it may be based, and the forecasted and other forward-looking information contained therein is subject to inherent uncertainties. We have referred to, and may in the future refer to, in our annual reports on Form 10-K, quarterly reports on Form 10-Q, and other documents that we file with, or furnish to, the SEC, historical, forecasted, and other forward-looking information published by sources such as the U.S. Census Bureau that we believe to be reliable. However, we have not independently verified this information and, with respect to the forecasted and forward-looking information, have not independently confirmed the assumptions and judgments upon which it is based. Forecasted and other forward-looking information is necessarily based on assumptions regarding future occurrences, events, conditions, and circumstances and subjective judgments relating to various matters and is subject to inherent uncertainties. Actual results may differ materially from the results expressed or implied by, or based upon, such forecasted and forward-looking information.

Because we have operations outside the United States and report our earnings in U.S. dollars, unfavorable fluctuations in currency values and exchange rates could have a material adverse effect on our results of operations. Because our reporting currency is the U.S. dollar, our non-U.S. operations face the additional risk of fluctuating currency values and exchange rates. Such operations may also face hard currency shortages and controls on currency exchange. Changes in the value of foreign currencies (principally Canadian dollars, Brazilian reals, Chilean pesos, and Argentine pesos) could have an adverse effect on our results of operations. We have, in the past, entered into foreign exchange contracts associated with certain of our indebtedness and may continue to enter into foreign exchange contracts associated with major equipment purchases to manage a portion of the foreign currency rate risk. We historically have not entered into currency rate hedges with respect to our exposure from operations, although we may do so in the future. There can be no assurance that fluctuation in foreign currencies and other foreign exchange risks will not have a material adverse effect on our financial position, results of operations, or cash flows.

Covenants and events of default in our debt instruments could limit our ability to undertake certain types of transactions and adversely affect our liquidity. Our Amended Credit Agreement (as defined below) and the indenture governing the 2029 Senior Notes (as defined below) contain a number of restrictive covenants that impose operating and financial restrictions on us and may limit our ability to engage in acts that may be in our long-term best interests, including, among others, restrictions on our ability to incur indebtedness, grant liens to secure indebtedness, engage in sale and leaseback transactions, and merge or consolidate or sell all or substantially all of our assets.

In addition, restrictive covenants in our Amended Credit Agreement require us to maintain specified financial ratios and satisfy other financial condition tests. Our ability to meet those financial ratios and tests can be affected by events beyond our control, and we may be unable to meet them.

A breach of the covenants or restrictions under our Amended Credit Agreement or under the indenture governing the 2029 Senior Notes could result in an event of default under the applicable indebtedness. Such a default may allow our creditors to accelerate the related debt. A payment default or an acceleration following an event of default under our Amended Credit Agreement or our indenture governing the 2029 Senior Notes could trigger an event of default under the other indebtedness obligation, as well as any other debt to which a cross-acceleration or cross-default provision applies, which could result in the principal of and the accrued and unpaid interest on all such debt becoming due and payable ahead of schedule. In addition, an event of default under our Amended Credit Agreement could permit the lenders under our Amended Credit Facility (as defined below) to terminate all commitments to extend further credit under that facility. Furthermore, if we were unable to repay any amounts due and payable under our Amended Credit Facility, those lenders could proceed against the collateral granted to them to secure that indebtedness, to the extent any such collateral is granted thereunder. In the event our lenders or noteholders accelerate the repayment of our borrowings, we and our subsidiaries may not have sufficient assets to repay that indebtedness.

As a result of these restrictions, we may be:

• limited in how we conduct our business and grow in accordance with our strategy;

• unable to raise additional debt or equity financing to operate during general economic or business downturns; or

• unable to compete effectively or to take advantage of new business opportunities.

In addition, our financial results, our level of indebtedness, and our credit ratings could adversely affect the availability and terms of any additional or replacement financing.

More detailed descriptions of our Amended Credit Agreement and the indenture governing the 2029 Senior Notes are included in filings made by us with the SEC, along with the documents themselves, copies of which are filed as exhibits to this annual report on Form 10-K and which provide the full text of these covenants.

We are subject to interest rate risk under our Amended Credit Facility. Borrowings under our Amended Credit Facility are at variable rates of interest based on (a) a “base rate” plus a margin of 0.500% to 1.500% or (b) Adjusted Term SOFR (i.e., Term SOFR Rate plus an adjustment of 0.10%), which is based upon the Secured Overnight Financing Rate (SOFR), plus a margin of 1.500% to 2.500%, and therefore expose us to interest rate risk. The “base rate” is the highest of (i) the Federal funds rate plus 0.5%, (ii) the U.S. prime rate, and (iii) one-month Adjusted Term SOFR plus 1.0%.

Our cash, cash equivalents and investments could be adversely affected if the financial institutions in which we hold our cash, cash equivalents and investments fail. We regularly maintain cash balances at third-party financial institutions in excess of the Federal Deposit Insurance Corporation insurance limit. If certain banks and financial institutions enter receivership or become insolvent in the future in response to financial conditions affecting the banking system and financial markets, our ability to access our existing cash, cash equivalents and investments may be threatened and could have a material adverse effect on our business and financial condition.

GENERAL RISK FACTORS

We are subject to a variety of other risks as a publicly traded U.S. manufacturing company. As a publicly traded U.S. manufacturing company, we are subject to a variety of other risks, each of which could adversely affect our financial position, results of operations or cash flows, or the price of our common stock. These risks include but are not limited to the following, in addition to the other risks described above:

• changes in general and global economic conditions, including impacts from rising inflation, supply chain disruptions, new, ongoing, or escalated geopolitical or military conflicts or tensions;

• compliance with a wide variety of health and safety laws and regulations and changes to such laws and regulations;

• the exertion of influence over us, individually or collectively, by a few entities with concentrated ownership of our stock;

• new or modified legislation related to health care, data privacy, AI, climate change or cybersecurity;

• compliance with Section 404 of the Sarbanes-Oxley Act of 2002, including the potential impact of compliance failures; and

• failure to meet the expectations of investors, including as a result of factors beyond the control of an individual company.

ITEM 7.     Management’s Discussion and Analysis of Financial Condition and Results of Operations

This Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with our Consolidated Financial Statements and related Notes and other financial information appearing elsewhere in this annual report on Form 10-K, and with Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our annual report on Form 10-K for our fiscal year ended December 31, 2024, filed with the SEC on February 19, 2025, which provides a discussion of our financial condition and results of operations for fiscal year 2024 compared to fiscal year 2023. The changes to our reportable segments in the current year did not have a material impact on our previously reported consolidated results of operations or financial position. Prior‑period segment information has been recast to conform to the current period presentation. The following discussion includes forward-looking statements that are based on the beliefs of our management, as well as assumptions made by, and information currently available to, our management. We encourage you to review the risks and uncertainties described in the sections titled “Cautionary Statement Regarding Forward-Looking Statements” and “Risk Factors” above. Our historical results are not necessarily indicative of the results that may be expected for any period in the future.

OVERVIEW

General

We are a leading provider of high-performance building solutions that meet the demands of builders, remodelers, and homeowners worldwide. We have leveraged our expertise serving the new home construction, repair and remodeling, and outdoor structures markets to become an industry leader known for innovation, quality, and reliability. To serve these markets, we operate in two reportable segments: Siding and OSB.

Executive Summary

In 2025, net sales dropped year over year by $233 million to $2.7 billion. Siding revenue increased by $131 million, or 8%, to $1.7 billion, attributable to 4% higher sales volumes and a 4% increase in prices. OSB revenue fell by $352 million to $832 million, primarily due to lower prices and sales volumes.

Net income declined year over year by $275 million to $146 million ($2.08 per diluted share). The primary drivers behind this decrease were a $252 million reduction in Adjusted EBITDA, and increases of $38 million in impairment charges, $24 million in foreign currency losses, $19 million in depreciation expense, and $10 million in stock-based compensation. Additionally, the absence of $14 million in business exit credits recognized in 2024 and a $7 million decrease in investment income contributed to the overall decline. These impacts were partially offset by a $90 million reduction in the tax provision. The year-over-year decrease in Adjusted EBITDA was driven by several factors, including a $292 million adverse effect from lower OSB prices and reduced sales volumes, partially offset by $91 million from higher Siding sales volumes and improved sales mix. In addition to price and volume impacts, the change in Adjusted EBITDA included increases of $11 million in marketing investments, $9 million in selling, general, and administrative expenses, $7 million of mill overhead and inventory absorption, and $8 million in tariff costs. The remaining decrease in Adjusted EBITDA relates to a decline of $15 million in Other Adjusted EBITDA, which primarily includes LPSA, corporate, and other minor products and services. Adjusted EBITDA is a non-GAAP Financial measure. Please see "Non-GAAP Financial Measures" below for more information about our use of non-GAAP financial measures in this annual report on Form 10-K and the reconciliation of Adjusted EBITDA to net income.

Demand for Building Products

Demand for our products correlates positively with new home construction and repair and remodeling activity in North America, which historically have been characterized by significant cyclicality. The U.S. Census Bureau published actual U.S. housing starts data on January 9, 2026. The U.S. Census Bureau reported on January 9, 2026, that 2025 actual single-family housing starts were 6% lower than those in 2024. Actual multi-family housing starts in 2025 were about 18% higher than those in 2024. Repair and remodeling activity is difficult to reasonably measure, but many indications suggest that repair and remodeling activity has declined modestly year-over-year.

Future economic conditions in the United States and the demand for homes are uncertain due to inflationary impacts on the economy, including interest rates, employment levels, consumer confidence, and financial markets, among other things. Additionally, we have experienced increases in material prices, supply disruptions, and labor challenges, which we continue to address as we work to meet the demands of builders, remodelers, and homeowners worldwide. The potential effect of these factors on our future operational and financial performance is uncertain. As a result, our past performance may not be indicative of future results.

The chart below, which is based on data published by U.S. Census Bureau, provides a graphical summary of new housing starts for single- and multi-family in the U.S., showing actual and rolling five- and ten-year averages for housing starts (in thousands).

November and December 2025 housing starts have not yet been published by the U.S. Census Bureau, and therefore, for the purpose of the chart above, we have used October 2025 housing starts previously published by the U.S. Census Bureau as the November and December 2025 actual housing starts.

Supply and Demand for Siding

Our Siding products are specialty building materials and are subject to competition from various siding technologies, including vinyl, stucco, wood, fiber cement, brick, and others. We believe we are the largest manufacturer of engineered wood siding in North America and South America. The global siding market is estimated to be approximately $120 billion of annual expenditure. We have consistently grown our Siding business above the underlying market growth rates. Our Siding business is generally less sensitive to new housing market cyclicality since a majority of its demand comes from other markets, including off-site structure producers and repair and remodel. Our growth in this market depends upon the continued displacement of vinyl, stucco, wood, fiber cement, brick, and other alternatives, our product innovation and our technological expertise in wood and wood composites to address the needs of our customers.

Supply and Demand for OSB

OSB is a commodity product, and it is subject to competition from manufacturers worldwide. Product supply is influenced primarily by fluctuations in available manufacturing capacity and imports. The ratio of overall OSB demand to capacity generally drives price. We cannot predict whether the prices of our OSB products will remain at current levels or increase or decrease in the future.

CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT ESTIMATES

Management’s Discussion and Analysis of Financial Condition and Results of Operations are based upon our Consolidated Financial Statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires management to make informed estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. Our financial position and/or results of operations may be materially different when reported under different conditions or when using different assumptions in the application of such policies. In the event estimates or assumptions prove to be different from actual amounts, adjustments are made in subsequent periods to reflect more current information. Our significant accounting policies are disclosed in “Note 1 - Summary of Significant Accounting Policies” of the Notes to the Consolidated Financial Statements and included in Item 8 of this annual report on Form 10-K. The following discussion addresses our most critical accounting policies, which are those that are both important to the portrayal of our financial condition and results of operations and that require significant judgment or use of complex estimates.

Long-lived Assets

Property, plant and equipment, and long-lived assets (including amortizable identifiable intangible assets) are tested for recoverability whenever events or changes in circumstances indicate that their carrying amount may not be recoverable, including but not limited to facility curtailments and asset abandonments. When such events occur, we group long-lived assets with other assets and liabilities at the lowest level for which identifiable cash flows exist. We compare the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group to the carrying amount of a long-lived asset or asset group. The cash flows are based on our best estimate of future cash flows derived from the most recent business projections. The significant assumptions used to determine estimated cash flows are the cash inflows and outflows directly resulting from the use of those assets in operations, including sales volume, product pricing, support costs, and other costs to operate. We recognize an impairment loss if the amount of the asset’s carrying value exceeds the asset’s estimated fair value. Fair value is estimated primarily using discounted expected future cash flows on a market-participant basis. If we recognize an impairment loss, the adjusted carrying amount of the asset becomes its new cost basis. For a depreciable long-lived asset, the new cost basis is depreciated (amortized) over the remaining estimated useful life of that asset.

Our impairment loss calculations contain uncertainties because they require management to make assumptions and to apply judgment to estimate future cash flows and asset fair values. We have not made any material changes in our impairment loss assessment methodology in the periods presented. We do not believe a material change in the estimates or assumptions that we use to calculate long-lived asset impairments is likely. However, if actual results are not consistent with our estimates and assumptions used in estimating future cash flows and asset fair values, we may be exposed to losses that could be material.

Revenue Recognition, Including Customer Program Costs

Revenue is recognized when obligations under the terms of a contract (e.g. , purchase orders) with our customers are satisfied; generally, this occurs with the transfer of control of our products to the customer at a point in time. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods. The shipping cost incurred by us to deliver products to our customers is recorded in cost of sales.

Our businesses routinely incur customer program costs to obtain favorable product placement, promote sales of products, and maintain competitive pricing. Customer program costs and incentives, including rebates and promotion and volume allowances, are accounted for as a reduction in net sales at the time the program is initiated and/or the revenue is recognized. The costs include, but are not limited to, volume allowances and rebates, promotional allowances, and cooperative advertising programs. These costs are recorded at the later of the time of sale or the implementation of the program based on management’s best estimates.

Our estimates are based on historical and projected experience for each type of program or customer. Volume allowances are accrued based on our estimates of customer volume achievement and other factors incorporated into customer agreements, such as new product purchases, store sell-through, merchandising support, and customer training.

Although we believe we can reasonably estimate customer volumes and support and the related customer payments at interim periods, it is possible that actual results could be different from previously estimated amounts. At the end of each year, a significant portion of the actual volume and support activity is known. Thus, we do not currently believe that a material change in the amounts recorded as customer program costs payable is reasonably likely. We had $50 million and $48 million accrued as customer rebates as of December 31, 2025 and 2024, respectively.

We ship some of our products to customers’ distribution centers on a consignment basis. We retain title to our products stored at the distribution centers. As our products are removed from the distribution centers by retailers and shipped to retailers’ stores, title passes from us to the retailers. At that time, we invoice the retailers and recognize revenue for these consignment transactions. We do not offer a right of return for products shipped to the retailers’ stores from the distribution centers.

NON-GAAP FINANCIAL MEASURES

In evaluating our business, we utilize non-GAAP financial measures that fall within the meaning of SEC Regulation G and Regulation S-K Item 10(e), which we believe provide users of the financial information with additional meaningful comparison to prior reported results. Non-GAAP financial measures do not have standardized definitions and are not defined by U.S. GAAP. In this annual report on Form 10-K, we disclose net income excluding interest expense, provision for income taxes, depreciation and amortization, stock-based compensation expense, loss on impairment, business exit credits and charges, product-line discontinuance charges, other operating credits and charges, net, loss on early debt extinguishment, investment income, pension settlement charges, other non-operating income (expense), income from discontinued operations, net of income taxes, and net income attributed to noncontrolling interest, as Adjusted EBITDA (Adjusted EBITDA), which is a non-GAAP financial measure. We have included Adjusted EBITDA in this report because we view it as an important supplemental measure of our performance and believe that it is frequently used by interested persons in the evaluation of companies that have different financing and capital structures and/or tax rates. We also disclose net income, excluding loss on impairment, business exit credits and charges, product-line discontinuance charges, interest expense outside of normal operations, other operating credits and charges, net, loss on early debt extinguishment, gain (loss) on acquisition, pension settlement charges, income from discontinued operations, net of income taxes, and net income attributed to noncontrolling interest, and adjusting for a normalized tax rate, as Adjusted Income (Adjusted Income), which is a non-GAAP financial measure. In addition, we disclose Adjusted Diluted EPS, calculated as Adjusted Income divided by diluted shares outstanding (Adjusted Diluted EPS), which is a non-GAAP financial measure. We believe that Adjusted Diluted EPS and Adjusted Income are useful measures for evaluating our ability to generate earnings and that providing these measures should allow interested persons to more readily compare the earnings for past and future periods. Reconciliations of Adjusted EBITDA, Adjusted Income and Adjusted Diluted EPS to their most directly comparable U.S. GAAP financial measures, net income, and net income per share of common stock - diluted, respectively, are presented below.

Adjusted EBITDA, Adjusted Income, and Adjusted Diluted EPS are not substitutes for the U.S. GAAP measures of net income and net income per share of common stock - diluted or for any other U.S. GAAP measures of operating performance. It should be noted that other companies may present similarly titled measures differently, and therefore, as presented by us, these measures may not be comparable to similarly titled measures reported by other companies. Adjusted EBITDA, Adjusted Income, and Adjusted Diluted EPS have material limitations as performance measures because they exclude items that are actually incurred or experienced in connection with the operation of our business.

OUR OPERATING RESULTS

The Company conducts business through three operating segments: Siding, OSB, and LP South America (LPSA). In the fourth quarter of 2025, the Company determined that LPSA did not meet the reportable segment criteria and beginning with the fourth quarter of 2025, the financial information for the LPSA operating segment is included in Other. These changes had no impact on our consolidated results of operations or financial position. Prior period segment information has been recast to conform to our current presentation. Our other operating segments, Siding and OSB remain reportable operating segments. Other now comprises our South American operations and other products that are not individually significant. See “Note 15 - Segment Information” of the Notes to the Consolidated Financial Statements included in Item 8 of this annual report on Form 10-K for further information regarding our reportable segments. The results of operations for each of our reporting segments are discussed below, as are results of operations for Other.

Siding

The Siding segment serves diverse end markets with a broad product portfolio of engineered wood siding, trim, soffit, and fascia. Our Siding is offered primed (LP ® SmartSide ® Trim & Siding, LP BuilderSeries ® Lap Siding, and LP ® Outdoor Building Solutions ® ) and pre-finished (LP ® SmartSide ® ExpertFinish ® Trim & Siding) to meet the needs of builders and installers in new construction and repair and remodeling applications.

Siding

Siding net sales increased for the year ended December 31, 2025 due to higher sales volumes and selling prices. Increases in the average sales price were primarily due to a combination of list price increases and favorable mix. ExpertFinish accounted for 10% of sales volume and 16% of net sales for the year ended December 31, 2025, contributing significantly to this favorable mix.

For the year ended December 31, 2025, Adjusted EBITDA increased $54 million compared to prior-year. This growth was driven by higher sales volume and higher selling prices of $91 million, partially offset by strategic investments in sales and marketing of $11 million, a $9 million increase of selling, general, and administrative expenses, $7 million of mill overhead and inventory absorption, and $7 million of tariff expenses.

OSB

The OSB segment manufactures and distributes OSB structural panel products, including the innovative value-added OSB product portfolio known as LP ® Structural Solutions (which includes LP ® FlameBlock ® Fire-Rated Sheathing, LP WeatherLogic ® Air & Water Barrier, LP ® TechShield ® Radiant Barrier, LP Legacy ® Premium Sub-Flooring, and LP ® TopNotch ® 350 Durable Sub-Flooring). Significant cost inputs to produce OSB (including approximate breakdown percentages for 2025) were as follows: wood fiber (26%), resin and wax (20%), labor and burden (20%), utilities (5%), and other manufacturing costs (29%).

For the year ended December 31, 2025, net sales decreased by $352 million due to a $260 million decrease in OSB prices and an $84 million decrease in sales volumes.

Adjusted EBITDA for the year ended December 31, 2025 decreased year-over-year by $291 million, due to lower average prices and sales volumes.

Other

Our other operations include our LPSA business that manufactures and distributes OSB structural panels and siding products in South America and certain export markets. Previously, all LPSA activity was presented as a separate reportable segment. Financial information related to LPSA is now included in Other. Additionally, Other includes unallocated corporate expenses, such as general administrative costs and stock-based compensation, along with other minor products, services, and closed operations that do not meet the criteria for discontinued operations.

For the year ended December 31, 2025, net sales and Adjusted EBITDA decreased year over year by $12 million and $15 million, respectively.

GENERAL CORPORATE AND OTHER EXPENSE, NET

General corporate and other expenses are primarily comprised of corporate overhead unrelated to business activities such as wages and benefits, professional fees, insurance, and other expenses for corporate functions, including executive officers, public company activities, tax, internal audits, and other corporate functions. General corporate and other expense, net, was $51 million in 2025, as compared to $46 million in 2024. This increase was driven by an increase in stock compensation expense.

LOSS ON IMPAIRMENTS

During 2025, we recorded $44 million of non-cash, pre-tax impairment charges. These charges included $24 million related to equipment that will not be utilized in future operations, $13 million related to the expiration and non-renewal of certain timber licenses, $4 million related to property, plant, and equipment associated with a facility closure, and $2 million primarily related to an operating lease asset associated with a previously closed facility. During 2024, we recorded $5 million of non-cash, pre-tax impairment charges related to property, plant, and equipment that will not be utilized in future operations. See further discussion in “Note 11 - Impairment of Long-Lived Assets” and “Note 1 - Summary of Significant Accounting Policies” of the Notes to the Consolidated Financial Statements included in Item 8 of this annual report on Form 10-K.

OTHER OPERATING CREDITS AND CHARGES, NET

For a discussion of other operating credits and charges, net, see “Note 10 - Other Operating and Non-Operating Income (Expense)” of the Notes to the Consolidated Financial Statements included in Item 8 of this annual report on Form 10-K.

NON-OPERATING INCOME (EXPENSE)

For a discussion of non-operating income (expense), see “Note 10 - Other Operating and Non-Operating Income (Expense)” of the Notes to the Consolidated Financial Statements included in Item 8 of this annual report on Form 10-K.

INCOME TAXES

We recognized a tax provision of $50 million in 2025, as compared to $140 million in 2024. For 2025, the primary differences between the U.S. statutory rate of 21% and the effective rate was related to state and foreign income taxes, partially offset by changes in uncertain tax positions. For 2024, the primary difference between the U.S. statutory rate of 21% and the effective tax rate was related to state and foreign income taxes. See “Note 6 – Income Taxes” of the Notes to the Consolidated Financial Statements included in Item 8 of this annual report on Form 10-K for further discussion. We paid $42 million and $124 million of income taxes net of refunds in 2025 and 2024, respectively.

LEGAL AND ENVIRONMENTAL MATTERS

For a discussion of legal and environmental matters involving us and the potential impact thereof on our financial position, results of operations, and cash flows, see Item 3 in this annual report on Form 10-K as well as “Note 12 - Commitments and Contingencies” of the Notes to the Consolidated Financial Statements included in Item 8 of this annual report on Form 10-K.

LIQUIDITY AND CAPITAL RESOURCES

Overview

Our principal sources of liquidity are existing cash and investment balances, cash generated by our operations, and our ability to borrow under such credit facilities as we may have in effect from time to time. We assess our liquidity in terms of our ability to generate cash to fund our short- and long-term cash requirements. As such, we project our anticipated cash requirements as well as cash flows generated from operating activities to meet those needs. We anticipate long-term cash uses may also include strategic acquisitions. On a long-term basis, we will continue to rely on our credit facility for any long-term funding not provided by operating cash flows. We may also, from time to time, issue and sell equity, debt, or hybrid securities or engage in other capital market transactions.

Our principal uses of liquidity are paying the costs and expenses associated with our operations, servicing outstanding indebtedness, paying dividends, 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 repurchases may be commenced, suspended, discontinued, or resumed, and the method or methods of affecting any such repurchases may be changed at any time, or from time to time, without prior notice.

Operating Activities

During 2025, we generated $382 million of cash from operations, as compared to $605 million in 2024. The decrease in cash provided by operations was primarily related to lower net income. At December 31, 2025 and 2024, we had working capital of $227 million and $216 million, respectively.

Investing Activities

During 2025, net cash used for investing activities was $291 million, as compared to $183 million in 2024. Capital expenditures for the year ended December 31, 2025, and 2024, were $291 million and $183 million, respectively, primarily related to siding conversion expenditures and growth and maintenance capital.

During 2024, we received $16 million in proceeds from our share of the sale of certain assets from an equity method investment. We also paid $17 million for an equity method investment in South America.

Capital expenditures in 2026 are expected to be approximately $400 million. We expect to fund our short-term and long-term capital expenditures in 2026 through cash on hand, cash generated from operations, and available borrowing under our Amended Credit Facility, as necessary.

Financing Activities

During 2025, cash used in financing activities was $141 million. We paid cash dividends of $78 million and $61 million to repurchase shares of LP common stock under the 2024 Share Repurchase Program during the year ended December 31, 2025. The remaining financing activities were primarily related to income tax withholding requirements associated with our employee stock-based compensation plans.

During 2024, cash used in financing activities was $292 million. We paid cash dividends of $74 million and $212 million to repurchase shares of LP common stock under the share repurchase programs authorized by LP's Board of Directors in 2022 and 2024, respectively, during the year ended December 31, 2024. The remaining financing activities were primarily related to income tax withholding requirements associated with our employee stock-based compensation plans.

CREDIT FACILITIES

In November 2022, LP entered into a Second Amended and Restated Credit Agreement with American AgCredit, PCA, as administrative agent and sole lead arranger, CoBank, ACB, as letter of credit issuer, and certain other lender parties (the Credit Agreement), relating to its revolving credit facility. On March 26, 2025, LP entered into the First Amendment to Second Amended and Restated Credit Agreement (the First Amendment) with American AgCredit, PCA, as administrative agent, CoBank, ACB, as letter of credit issuer, and the lenders and voting participants party thereto, which amended the Credit Agreement (the Amended Credit Agreement) to (1) increase the aggregate principal amount for the credit facility (the Amended Credit Facility) from $550 million to $750 million, (2) increase the sub-limit for letters of credit from $60 million to $75 million, (3) change the interest rate for revolving borrowing, (4) change the capitalization ratio limit, and (5) extend the maturity date to March 26, 2032. As of December 31, 2025, we had no outstanding borrowings pursuant to the Amended Credit Facility.

The Amended Credit Agreement contains various restrictive covenants and customary events of default, the occurrence of which could result in the acceleration of our obligation to repay the indebtedness outstanding thereunder. The Amended Credit Agreement also contains certain financial covenants that, among other things, require us and our consolidated subsidiaries to have, as of the end of each fiscal quarter, a capitalization ratio ( i.e. , funded debt less unrestricted cash to total capitalization) of no more than 65%. As of December 31, 2025, we were in compliance with all financial covenants under the Amended Credit Agreement.

In May 2024, LP entered into a new letter of credit facility agreement (the LOC Facility Agreement), replacing the letter of credit facility agreement dated May 2020. The LOC Facility Agreement provides for the funding of letters of credit up to an aggregate outstanding amount of $20 million, which may be secured by certain cash collateral of LP (the Letter of Credit Facility). The LOC Facility Agreement provides for a letter of credit fee, due quarterly, ranging from 1.000% to 1.875% of the daily available amount to be drawn on each letter of credit issued under the Letter of Credit Facility. The LOC Facility Agreement contains similar affirmative, negative, and financial covenants as those set forth in the Amended Credit Agreement, including the capitalization ratio covenant. All amounts outstanding under the Letter of Credit Facility become due on April 15, 2029. As of December 31, 2025, we were in compliance with all financial covenants under the Letter of Credit Facility.

OTHER LIQUIDITY MATTERS

2029 Senior Notes

In March 2021, we issued the 3.625% Senior Notes due in 2029 in the aggregate principal amount of $350 million, which mature on March 15, 2029 (the 2029 Senior Notes). As of December 31, 2025, future interest payments associated with the 2029 Senior Notes totaled $41 million, with $13 million payable within 12 months of such date. For additional information regarding the 2029 Senior Notes, please see “Note 8 - Long-Term Debt” of the Notes to the Consolidated Financial Statements included in Item 8 of this annual report on Form 10-K.

Contingency Reserves

Contingency reserves, which represent an estimate of future cash needs for various contingencies (principally, environmental reserves), totaled $27 million at December 31, 2025, of which $1 million is estimated to be payable within one year of such date. There is inherent uncertainty concerning the reliability and precision of such estimates, and as such, the amounts ultimately paid in resolving these contingencies could exceed the current reserves by a material amount.

Leases

We have lease arrangements for real estate, mobile equipment at our manufacturing facilities, rail cars to transport our products, and a fleet of vehicles. As of December 31, 2025, we had fixed lease payment obligations of $32 million, with $10 million payable within 12 months of such date.

Other Purchase Obligations

Our other purchase obligations primarily consist of obligations related to information technology infrastructure. As of December 31, 2025, we had other purchase obligations of $39 million, with $22 million payable within 12 months of such date.

Off-Balance Sheet Arrangements

As of December 31, 2025, we had standby letters of credit of $14 million outstanding related to collateral for environmental impact on owned properties, a deposit for forestry license, and insurance collateral, including workers’ compensation.
