YoY shift: Neutral

Year-over-year tone shift - average net-tone change across Risk Factors and MD&A vs the prior 10-K. This filing is -0.03pp more bearish than last year's.

Why YoY instead of absolute: the LM lexicon has ~6.6× more negative words than positive (legal/risk-disclosure language is heavy on hedging), so every 10-K reads bearish on raw tone. Year-over-year change strips that bias and surfaces the actual shift in management's framing.

Item 1A. Risk Factors

The following risk factors and other information included in this Annual Report on Form 10-K should be carefully considered. We believe these are the principal material risks currently facing our business; however, additional risks and uncertainties not presently known to us or that we presently deem less significant may also impair our business operations. If any of the following risks or those disclosed in our other Securities and Exchange Commission filings occurs, our business, financial condition or results of operations could be materially adversely affected.

Business and Operational Risks

We May Not be Able to Compete Favorably in the Competitive HVACR Business.

Substantially all of the markets in which we operate are competitive. The most significant competitive factors we face are product availability, product reliability, energy efficiency, product performance, service, and price, with the relative importance of these factors varying among our product lines. Other factors that affect competition in the HVACR market include the development and application of new technologies, reputation of our company and brands, global supply chain constraints, and new product introductions. In some of the markets in which we compete, such as parts and supplies, distribution, and service of commercial heating and cooling equipment, barriers to entry are lower, which has led to highly competitive markets consisting of various-sized entities, ranging from small or local operators to large regional businesses. We may not be able to adapt to market changes as quickly or effectively as our current and future competitors. Also, the establishment of manufacturing operations in low-cost countries could provide cost advantages to existing and emerging competitors. Some of our competitors may have greater financial resources than we have, allowing them to invest in more extensive research and development and/or marketing activity and making them better able to withstand adverse HVACR market conditions. Current and future competitive pressures may cause us to reduce our prices or lose market share, or could negatively affect our cash flow, all of which could have a material adverse effect on our results of operations. Negative media reports about us or our businesses,

whether accurate or inaccurate, could damage our reputation and relationships with our customers and suppliers, cause customers and suppliers to terminate their relationship with us, or impair our ability to effectively compete, which could adversely affect our business, financial condition, results of operations and cash flows.

If We Cannot Successfully Develop and Market New Products or Execute Our Business Strategy, Our Results of Operations Could be Adversely Impacted.

Our future success depends on our continued investment in research and new product development as well as our ability to commercialize new HVACR technological advances in domestic and global markets. The integration of any such new products or technologies into our business may also require the development of new processes and the expenditure of significant financial and operational resources. If we are unable to continue to timely and successfully develop and market new products, achieve technological advances, or extend our business model and technological advances into new markets, our business and results of operations could be adversely impacted.

Lennox operates a direct-to-dealer network, meaning we manufacture products and sell them directly to select, independent home service companies. We rely on our direct sales channel for a substantial portion of our revenue. Our direct-to-dealer network also creates a large installed base of HVACR equipment, and creates opportunities for longer term service, monitoring, solutions, and retrofit revenue. If we are unable to continue to execute our strategy, whether due to changes in economic conditions, a failure to anticipate changing customer needs, entry of new competitors into the low-barrier distribution business, or for any other reason, our revenue could decline, which could in turn adversely impact our product pull-through and our ability to grow revenue.

To remain competitive, we are engaged in various manufacturing rationalization actions designed to achieve our strategic priorities of manufacturing, sourcing, and distribution excellence and of lowering our cost structure. For example, we are continuing to reorganize our North American distribution network in order to better serve our customers’ needs by deploying parts and equipment inventory closer to them. In such case, our results of operations and profitability may be negatively impacted, making us less competitive and potentially causing us to lose market share.

Our Ability to Meet Customer Demand and Maintain Profitability may be Limited by Our Single-Location Production Facilities, Reliance on Certain Key Suppliers, and Unanticipated Significant Shifts in Customer Demand.

We manufacture many of our products at single-location production facilities. In certain instances, we heavily rely on suppliers who also may concentrate production in single locations or source unique, necessary products from only one supplier. As a result, any significant interruptions in production at one or more of our facilities or at a facility of one of our key suppliers, any failure to maintain favorable relationships with our suppliers, or any termination of a key supplier relationship, could negatively impact our profitability and ability to deliver our products to our customers.

Further, even with all of our facilities running at full production, we could potentially be unable to fully meet demand during an unanticipated period of exceptionally high demand. This inability to fully meet demand would be exacerbated if a single-location production facility is disrupted due to external factors including, but not limited to, a climate-related disaster, pandemic or epidemic, geopolitical instability, or war. Our inability to meet our customers’ demand for our products could have a material adverse effect on our business, financial condition, and results of operations. Conversely, reduced demand for our products and services could unfavorably impact our absorption of fixed costs. Any of these results could materially and adversely affect our business, financial condition, results of operations and cash flows.

Our Results of Operations May Suffer if We Cannot Continue to License or Enforce the Intellectual Property Rights on Which Our Businesses Depend or if Third Parties Assert That We Violate Their Intellectual Property Rights.

We rely upon patent, copyright, trademark and trade secret laws and agreements to establish and maintain intellectual property rights in the products we sell. Our intellectual property rights could be challenged, invalidated, infringed, circumvented, or be insufficient to permit us to take advantage of current market trends or to otherwise provide competitive advantages. Further, the laws of certain countries do not protect proprietary rights to the same extent as the laws of the U.S.

Third parties may also claim that we are infringing upon their intellectual property rights. If we do not license infringed intellectual property or if we are required to substitute similar technology from another source, our operations could be adversely affected. Even if we believe that intellectual property claims are without merit, they can be time consuming, require significant resources and be costly to defend. Claims of intellectual property infringement also might require us to redesign affected products, pay costly damage awards, or face injunctions prohibiting us from manufacturing, importing, marketing, or

selling certain of our products. Even if we have agreements to indemnify us, indemnifying parties may be unable or unwilling to do so.

Our Operations Can Be Adversely Affected By Our Ability to Attract, Motivate, Develop, and Retain Our Employees, Labor Shortages and Work Stoppages, Turnover, Labor Cost Increases and Other Labor Relations Problems.

We are committed to attracting, motivating, developing, and retaining our employees to remain an employer of choice. Despite our efforts, we have experienced, and could continue to experience, employee turnover, particularly in our manufacturing and distribution locations. A number of factors may adversely affect the labor force available or increase labor costs, including labor shortages from high employment levels and related competition or labor stoppages due to disputes or strikes. In addition, as of December 31, 2025, approximately 26% of our core workforce locations were unionized. Our Marshalltown, Iowa-based union ratified a five-year labor agreement on November 1, 2021; however, the results of future negotiations with unions are uncertain. If we are unsuccessful in meeting these challenges, our results of operations could be materially impacted.

Artificial Intelligence Technologies Could Present Business, Compliance, and Reputational Risks.

Recent technological advances in artificial intelligence (“AI”) and machine-learning technology both present opportunities and pose risks to us. If we fail to keep pace with rapidly evolving technological developments in AI, our competitive position and business results may suffer. We face risk of competitive disadvantage if our competitors more effectively use AI to better serve customers, drive internal efficiencies, and/or create new or enhanced products or services. We have begun to incorporate AI capabilities into our operations and the introduction of these technologies, particularly generative AI, into internal processes, customer engagements, and/or new and existing product offerings may result in new or expanded risks and liabilities, including due to enhanced governmental or regulatory scrutiny, litigation, compliance issues, ethical concerns, confidentiality or security risks, as well as other factors that could affect our business, reputation, and financial results. In addition, our personnel could, unbeknownst to us, utilize AI and machine learning-technology while carrying out their responsibilities. The use of AI in the development of our products and services could also cause of intellectual property, as well as subject us to risks related to intellectual property or , data privacy and cybersecurity. The use of AI can lead to consequences, including generating content that appears correct but is factually , or otherwise , or that results in biases and discriminatory outcomes, which could our reputation and business and us to risks related to or in the output of such technologies. Finally, multiple jurisdictions have either already put in place laws and regulations governing the use of AI, or are considering such laws and regulations. Compliance with these laws, regulations, and industry frameworks may limit our ability to leverage AI or require us to substantially revise our approach to its use.

Industry Risks

Our Financial Performance Is Affected by the Conditions and Performance of the U.S. Construction Industry.

Our business is affected by the performance of the U.S. construction industry. Our sales in the residential and commercial new construction markets correlate to the number of new homes and buildings that are built, which in turn is influenced by cyclical factors such as interest rates, inflation, availability of financing, consumer spending habits and confidence, employment rates and other macroeconomic factors over which we have no control. Our sales may not improve, or improvement may be limited or lower than expected.

Cooler than Normal Summers and Warmer than Normal Winters May Depress Our Sales.

Demand for our products and services is seasonal and strongly affected by the weather. Cooler than normal summers depress our sales of replacement air conditioning and refrigeration products and services. Similarly, warmer than normal winters have the same effect on our heating products and services. Extreme weather events, conditions, and water scarcity, as a result of climate change or other factors, may exacerbate fluctuations in typical weather patterns, creating financial risks to our business.

Price Volatility for Commodities and Components We Purchase or Significant Supply Interruptions Could Have an Adverse Effect on Our Cash Flow or Results of Operations.

We depend on raw materials, such as steel, copper and aluminum, and components purchased from third parties to manufacture our products. Some of these third-party suppliers are located outside of the U.S. We generally concentrate purchases for a given raw material or component with a small number of suppliers. If a supplier is unable or unwilling to meet

our supply requirements, including suffering any disruptions at its facilities or in its supply chain, we could experience supply interruptions or cost increases, either of which could have an adverse effect on our results of operations. For example, disruptions have occurred due to supplier capacity constraints, labor shortages, port congestion, logistical problems, the COVID-19 pandemic, and other issues. Some of these disruptions have resulted in supply chain constraints affecting our business including our ability to timely produce and ship our products.

Similarly, suppliers of components that we purchase for use in our products may be affected by rising material costs and inflation and pass these increased costs on to us. Although we regularly pre-purchase a portion of our raw materials at fixed prices each year to hedge against price increases, an increase in raw materials prices not covered by our fixed price arrangements could significantly increase our cost of goods sold and negatively impact our margins if we are unable to effectively pass such price increases on to our customers. Alternatively, if we increase our prices in response to increases in the prices or quantities of raw materials or components or if we encounter significant supply interruptions, our competitive position could be adversely affected, which may result in depressed sales and profitability.

Additionally, the effects of extreme weather events and natural disasters, long-term changes in temperature levels, water availability, increased cost for decarbonizing process heating, supply costs impacted by increasing energy costs, or energy costs impacted by carbon prices or offsets, as a result of climate change or other factors, may exacerbate supply chain constraints and disruption. Resulting supply chain constraints have required, and may continue to require, in certain instances, alternative delivery arrangements and increased costs and could have a material adverse effect on our business and operations.

In addition, we use derivatives to hedge price risk associated with forecasted purchases of certain raw materials. Our hedged prices could result in paying higher or lower prices for commodities as compared to the market prices for those commodities when purchased.

We May Incur Substantial Costs as a Result of Product Liability, Warranty Claims, or Recalls.

The development, manufacture, sale, and use of our products involve warranty and product liability claims and other liabilities and risks for the installation, use, and service of our products. Our product liability insurance coverage may not be sufficient to cover claims or damage awards or we may not be able to obtain such insurance on acceptable terms in the future, if at all, or obtain insurance that will provide adequate coverage against potential claims. Product liability claims can be expensive to defend, regardless of the ultimate outcome. A significant unsuccessful product liability defense could have a material adverse effect on our financial condition and results of operations.

In addition, for some of our HVACR products, we provide warranty terms ranging from one to 20 years to customers for certain components such as compressors or heat exchangers. Warranty claims are not covered by our product liability insurance and certain product liability claims may also not be covered by our product liability insurance. For certain limited products, we used to provide lifetime warranties. Warranties of such extended lengths pose a risk to us as actual future costs may exceed our current estimates of those costs. Warranty expense is recorded on the date that revenue is recognized and requires significant assumptions about what costs will be incurred in the future. We may be required to record material adjustments to accruals and expense in the future if actual costs for these warranties are different from our assumptions. Our product warranty liability was $167.2 million as of December 31, 2025.

We maintain strict quality controls and procedures. However, we cannot be certain that these controls and procedures will reveal defects in our products or their component parts or raw materials, which may not become apparent until after the products have been placed in use in the market. Accordingly, there is a risk that products will have defects that could require a product recall or field corrective action, either voluntarily or at the direction of a governmental authority. Product recalls and field corrective actions can be expensive to implement and may damage our reputation, customer relationships and market share.

Further, our business depends on the strong brand reputations we have developed. If a reputation is damaged due to actual, potential, or perceived product and service quality issues, we may face difficulty maintaining our market share and pricing with respect to some of our products, which could reduce our sales and profitability.

Legal, Tax, and Regulatory Risks

Changes in Environmental and Climate-Related Legislation, Government Regulations, or Policies Could Have an Adverse Effect on Our Results of Operations.

The sales, gross margins, and profitability for each of our segments could be directly impacted by changes in legislation, government regulations, or policies (collectively, “LRPs”) relating to global climate change and other environmental initiatives and concerns. These LRPs, implemented under global, national, and sub-national climate objectives or policies, can include changes in environmental and energy efficiency standards and tend to target the global warming potential of refrigerants and hydrofluorocarbons, equipment energy efficiency, and combustion of fossil fuels as a heating source. Many of our products consume energy and use refrigerants and hydroflurocarbons. LRPs that seek to reduce greenhouse gas emissions may require us to make increased capital expenditures to develop or market new products to meet new LRPs. Further, our customers and the markets we serve may impose emissions or other environmental standards through LRPs or consumer preferences that may require additional time, capital investment, or technological advancement. Our inability or delay in developing or marketing products that match customer demand while also meeting applicable LRPs may negatively impact our financial condition and results of operations.

There continues to be a lack of consistent climate legislation and regulations, which creates economic and regulatory uncertainty. Such regulatory uncertainty could adversely impact the demand for energy efficient buildings and could increase costs of compliance. Additionally, the extensive and frequently changing legislation and regulations could impose increased liability for remediation costs and civil or criminal penalties in cases of non-compliance. Because these laws are subject to change, we are unable to predict the future costs resulting from environmental compliance. Likewise, a failure to comply with any current or future sustainability-related reporting requirements, as established by U.S. and international regulators, may result in loss of business, regulatory penalties, litigation, and/or reputational damage. Further, we may face adverse reputational risks due to our products and manufacturing operations consuming energy or using refrigerants and hydroflurocarbons.

Stakeholders are increasingly scrutinizing environmental, social and governance (“ESG”) practices, and stakeholders’ expectations regarding ESG practices are diverse, rapidly changing, and sometimes in conflict. If we are unable to satisfy the evolving ESG-related expectations of certain stakeholders, particularly as it relates to climate change, we may suffer reputational harm, which may cause our stock price to decrease or cause certain investors and financial institutions not to purchase our securities or provide us with capital or credit on favorable terms, which may cause our cost of capital to increase. In addition, our reputation and customer relationships may be damaged as a result of practices that could be associated with ESG, including as it relates to climate-related disclosures. A failure or perceived failure by us in this regard may damage our reputation and adversely affect our results of operations and financial condition.

Changes in Tax Laws and Interpretations Could Adversely Impact our Effective Tax Rates and Financial Results.

We are subject to income taxes in the U.S. as well as certain foreign jurisdictions. Tax laws and regulations are continuously evolving with corporate tax reform, base-erosion efforts, global minimum tax, and increased transparency continuing to be high priorities in many tax jurisdictions in which we operate. We continue to monitor new tax legislation or other developments since significant changes in tax legislation, or in the interpretation of existing legislation, could materially and adversely affect our financial condition and results of operations.

Certain countries in which we have operations have implemented, or are in the process of implementing, legislation or practices inspired by the base erosion and profit shifting project undertaken by the Organization for Economic Co-operation and Development (“OECD”). In December 2021, the OECD issued its guidance on the Global Anti-Base Erosion (“GloBE”) rules with the purpose of ensuring multinational companies pay a minimum level tax on the income generated in each of the jurisdictions where they operate (“Pillar Two”). In December 2022, the European Council attained a consensus on Pillar Two to implement a global minimum corporate tax rate of 15%, and many European Union and G20 countries began incorporating and implementing OECD guidelines in 2024. Our effective tax rate for 2025 incorporates our estimated Pillar Two tax liability. We are continuing to evaluate the potential impact on future periods of the Pillar Two framework, pending legislative adoption by individual countries, as such changes could result in an increase in our effective tax rate.

Further, the increased scrutiny of international tax arrangements and continuous changes to countries’ tax legislation may also affect the policies and decisions of tax authorities with respect to certain income tax and transfer pricing positions taken by the Company in prior or future periods. We are regularly subject to audits by tax authorities, and such audits could result in

changes in our tax reserves for our historic or future tax positions and transfer pricing policies, which could significantly adversely impact our effective tax rates and financial results.

For more information, see Note 12 in the Notes to our Consolidated Financial Statements.

Changes in U.S. Trade Policy, Including the Imposition of Tariffs and the Resulting Consequences, Could Have an Adverse Effect on Our Results of Operations.

The U.S. government has made changes in U.S. trade policy over the past several years. These changes include renegotiating and terminating certain existing bilateral or multi-lateral trade agreements, such as the U.S.-Mexico-Canada Agreement (“USMCA”), and initiating tariffs on certain foreign goods from a variety of countries. In addition, the U.S. presidential administration has imposed increased tariffs on imports from Canada and Mexico for goods not covered by the USMCA. The USMCA is subject to review and renewal in 2026, and there can be no assurance that any newly negotiated terms in the USMCA will not adversely affect our business or operations. These changes in U.S. trade policy have led, and may again lead, to foreign governments enacting responsive trade policies that increase the difficulty or cost of doing international business or trade. As a consequence, the sales, gross margins, and profitability for each of our segments could be directly impacted by changes in tariffs and trade agreements.

We cannot predict the extent to which the U.S. or other countries will impose new or additional quotas, duties, tariffs, taxes, non-tariff barriers, or other similar restrictions upon the import or export of our products in the future, nor can we predict future trade policy or the terms of any renegotiated trade agreements and their impact on our business. The continuing adoption or expansion of trade restrictions, the occurrence of trade tensions, or other governmental actions related to tariffs or trade agreements or trade policies, may negatively affect demand for our products, costs, customers, suppliers, and the U.S. economy, which in turn could have a material adverse effect on our business, results of operations, and financial condition.

Our Reputation, Ability to Do Business, and Results of Operations Could be Impaired By Improper Conduct By Any of Our Employees, Agents, or Business Partners.

We are subject to regulation under a wide variety of U.S. federal and state and non-U.S. laws, regulations and policies (including those related to tariffs and trade barriers, investments, taxation, exchange controls, employment regulations, anti-corruption, anti-bribery, export and import compliance, anti-trust and money laundering). In particular, the U.S. Foreign Corrupt Practices Act and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to government officials for the purpose of obtaining or retaining business, and we operate in many parts of the world that have experienced government corruption to some degree. We cannot provide assurance our internal controls will always protect us from, or identify any, improper conduct of our employees, agents and business partners. Any such violation of law or improper actions could subject us to civil or in the U.S. and other jurisdictions, could lead to substantial civil or , monetary and non-monetary and related shareholder lawsuits, could lead to increased costs of compliance, and could our reputation, our business and results of operations.

We are Subject to Claims, Lawsuits, and Other Litigation That Could Have an Adverse Effect on Our Results of Operations.

In addition to product liability and warranty claims as described above, we are involved in various claims and lawsuits incidental to our business, including those involving intellectual property infringement, labor relations, alleged exposure to asbestos-containing materials, and environmental matters, some of which claim significant damages. Estimates related to our claims and lawsuits, including estimates for asbestos-related claims and related insurance recoveries, involve numerous uncertainties. Given the inherent uncertainty of litigation and estimates, we cannot be certain that existing claims or litigation or any future adverse legal developments will not have a material adverse impact on our financial condition.

General Risk Factors

Global General Business, Economic and Market Conditions Could Adversely Affect Our Financial Performance and Limit Our Access to the Capital Markets.

Our business may be materially and adversely impacted by changes in U.S. or global economic conditions, including recessions, economic downturns, inflation, deflation, fluctuations in interest rates, consumer spending rates, energy availability and commodity prices, and the effects of governmental initiatives to manage economic conditions. Disruptions in U.S. or global financial and credit markets or increases in the costs of capital may also have an adverse impact on our business. The tightening, unavailability or increased cost of credit adversely affects the ability of our customers to obtain financing for significant purchases and operations, resulting in a decrease in sales of our products and services and may impact the ability of

our customers to make payments to us. Similarly, tightening of available credit may adversely affect our supplier base and increase the potential for one or more of our suppliers to experience financial distress or bankruptcy. Our business may also be adversely affected by future decreases in the general level of economic activity and increases in borrowing costs, which may cause our customers to cancel, decrease or delay their purchases of our products and services.

If financial markets were to deteriorate, or costs of capital were to increase significantly due to a lowering of our credit ratings, prevailing industry conditions, the volatility of the capital markets or other factors, we may be unable to obtain new financing on acceptable terms, or at all. A deterioration in our financial performance could also limit our future ability to access amounts currently available under our Credit Agreement or to issue notes pursuant to our commercial paper program, as more fully described below.

We cannot predict the likelihood, duration, or severity of any future disruption in financial markets or any adverse economic conditions in the U.S. and other countries.

Extraordinary Events Beyond our Control, Including Conflicts, Wars, Natural Disasters, Public Health Crises, Terrorist Acts, or Other Civil or Political Disruptions, Could Negatively Impact our Business, Which May Affect our Financial Condition, Results of Operations or Cash Flows.

External disruptions, including, but not limited to, conflicts, wars, natural disasters (the nature and severity of which may be impacted by climate change), public health crises, terrorist acts, or other civil or political disruptions, may cause significant damage or disruption to our operations, employees, facilities, systems, suppliers, supply chain, distributors, resellers, or customers in the U.S. and internationally for extended periods of time and could also affect demand for our products. The extent to which any extraordinary event impacts us depends on numerous factors and future developments that we are not able to predict, including the duration and scope of the event; governmental, business, and individuals’ actions in response to the event; our ability to maintain sufficient qualified personnel; global supply chain disruptions caused by the event; and the impact on economic activity, including financial market instability.

Our International Operations Subject Us to Risks Related to Foreign Currencies Fluctuations and Other Risks.

We earn revenue, pay expenses, own assets, and incur liabilities in countries using currencies other than the U.S. dollar including the Canadian dollar, the Mexican peso, and the Euro. Our Consolidated Financial Statements are presented in U.S. dollars and we translate revenue, income, expenses, assets, and liabilities into U.S. dollars at exchange rates in effect during or at the end of each reporting period. Therefore, increases or decreases in the value of the U.S. dollar relative to other currencies may affect our net operating revenues, operating income and the value of balance sheet items denominated in foreign currencies. Because of the geographic diversity of our operations, weaknesses in some currencies might be offset by strengths in others over time. However, we cannot assure that fluctuations in foreign currency exchange rates, particularly the strengthening of the U.S. dollar against major currencies, would not materially affect our financial results.

In addition to the currency exchange risks inherent in operating in foreign countries, our international sales and operations are also sensitive to changes in foreign national priorities, including government budgets, as well as to geopolitical and economic instability. Net sales outside of the U.S. comprised approximately 7% of our total net sales in 2025. International transactions may involve increased financial and legal risks due to differing legal systems and customs in foreign countries. The ability to manage these risks could be difficult and may limit our operations and make the manufacture and sale of our products internationally more difficult, which could negatively affect our business and results of operations.

Cyber Attacks and Other Disruptions or Misuse of Information Systems We Rely Upon Could Affect Our Ability to Conduct Our Business Effectively.

Our information systems and those of our business partners are important to our business activities. We also outsource various information systems, including data management, to third-party service providers. Despite our security measures as well as those of our business partners and third-party service providers, the information systems we rely upon may be vulnerable to interruption or damage from cyber attacks, computer viruses, worms or other destructive or disruptive software, process breakdowns, denial of service attacks, malicious social engineering or other malicious activities, or any combination thereof. Further, as AI technologies advance, new and increasingly sophisticated attack methods are emerging, including fraud involving impersonation technologies or other forms of generative AI that enhance the scale, frequency, and effectiveness of cyber threats. Attempts have been made to attack our information systems, but we do not believe that material has resulted. While we have implemented controls and taken other preventative actions to these systems future attacks, we can give no assurance that these controls and preventative actions will be . Any of data security

could result in a disruption of our services, improper disclosure of personal data or confidential information, or online fraud or cybertheft, which could harm our reputation, require us to expend resources to remedy such a security breach or defend against further attacks, or subject us to liability under laws that protect personal data, resulting in increased operating costs or loss of revenue.

We May Not be Able to Successfully Integrate and Operate Businesses that We May Acquire nor Realize the Anticipated Benefits of Strategic Relationships We May Form.

From time to time, we may seek to complement or expand our businesses through strategic acquisitions, joint ventures, and strategic relationships. For example, in 2025, we completed the acquisition of Duro Dyne and Supco. The success of this and any other transactions will depend, in part, on our ability to timely identify those relationships, negotiate and close the transactions and then integrate, manage, and operate those businesses profitably. If we are unable to successfully complete these actions, we may not realize the anticipated benefits associated with such transactions, which could adversely affect our business and results of operations.

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

The following discussion should be read in conjunction with the other sections of this report, including the Consolidated Financial Statements and related Notes to the Consolidated Financial Statements in Item 8, “Other Financial Statement Details,” of this Annual Report on Form 10-K.

Forward-Looking Statements

This Annual Report on Form 10-K contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Exchange Act that are based on information currently available to management as well as management’s assumptions and beliefs as of the date hereof. All statements, other than statements of historical fact, included in this Annual Report on Form 10-K constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by the words “may,” “will,” “should,” “plan,” “predict,” “anticipate,” “believe,” “intend,” “estimate” and “expect” and similar expressions. Statements that are not historical should also be considered forward-looking statements. Such statements reflect our current views with respect to future events. Readers are cautioned not to place undue reliance on these forward-looking statements. We believe these statements are based on reasonable assumptions; however, such statements are inherently subject to risks and uncertainties, including but not limited to the specific uncertainties discussed elsewhere in this Annual Report on Form 10-K and the risk factors set forth in Item 1A. Risk Factors in this Annual Report on Form 10-K. These risks and uncertainties may affect our performance and results of operations. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may differ materially from those in the forward-looking statements. We disclaim any intention or obligation to update or review any forward-looking statements or information, whether as a result of new information, future events or otherwise unless required by law.

The following are some of the factors that could cause actual results to differ materially from those expressed or implied in forward-looking statements:

• competition in the HVACR business;

• our ability to successfully develop and market new products or execute our business strategy, including the implementation of price increases for products and services;

• our ability to meet and anticipate customer demands;

• our ability to continue to license or enforce our intellectual property rights;

• our ability to attract, motivate, develop and retain our employees, as well as labor relations problems;

• artificial intelligence technologies;

• a decline in new construction activity and related demand for our products and services;

• the impact of weather on our business;

• the impact of higher raw material prices and significant supply interruptions;

• product liability, warranty claims, or recalls;

• changes in environmental and climate-related legislation or government regulations or policies;

• changes in tax legislation;

• the impact of new or increased trade tariffs;

• improper conduct by any of our employees, agents, or business partners;

• litigation risks;

• general economic conditions in the U.S. and abroad;

• extraordinary events beyond our control, such as conflicts, wars, natural disasters, public health crises, terrorist acts, or other civil or political disruptions;

• risks associated with our international operations;

• cyber attacks and other disruptions or misuse of information systems; and

• our ability to successfully realize, complete and integrate acquisitions.

Business Overview

We operate in two reportable business segments of the HVACR industry, Home Comfort Solutions and Building Climate Solutions. In addition to the two major business segments, Corporate and Other is also reported as a segment. For more detailed information regarding our reportable segments, see Note 3 in the Notes to the Consolidated Financial Statements.

In the fourth quarter of 2023, we completed the sale of our European businesses. The European businesses were presented with the Corporate and Other business segment until their divestiture.

In October 2025, we completed the acquisition of Duro Dyne and Supco, a robust portfolio of HVAC parts and supplies that complement our existing residential and commercial offerings. Duro Dyne is reported in our Business Climate Solutions segment, and Supco is reported in our Home Comfort Solutions segment.

In October 2023, we completed the acquisition of AES, which is included in our Building Climate Solutions segment. AES is a company dedicated to service and sustainability in the light commercial markets across North America.

We sell our products and services through a combination of direct sales, distributors and company-owned stores. The demand for our products and services is seasonal and can be significantly impacted by the weather. Warmer than normal summer temperatures generate demand for replacement air conditioning and refrigeration products and services, and colder than normal winter temperatures have a similar effect on heating products and services. Conversely, cooler than normal summers and warmer than normal winters depress the demand for HVACR products and services. In addition to weather, demand for our products and services is influenced by national and regional economic and demographic factors, such as interest rates, the availability of financing, regional population and employment trends, new construction, general economic conditions and consumer spending habits and confidence. A substantial portion of the sales in each of our business segments is attributable to replacement business, with the balance comprised of new construction business.

The principal elements of cost of goods sold are components, raw materials, factory overhead, labor, estimated costs of warranty expense and freight and distribution costs. The principal raw materials used in our manufacturing processes are steel, aluminum and copper. In recent years, pricing volatility for these commodities and related components has impacted us and the HVACR industry in general. We seek to mitigate the impact of certain commodity price volatility through a combination of pricing actions, vendor contracts, improved production efficiency and cost reduction initiatives. We also partially mitigate volatility in the prices of these commodities by entering into futures contracts and fixed forward contracts.

In the fourth quarter of 2025, we changed the method of accounting for our inventories from last-in-first-out (“LIFO”) to first-in-first-out (“FIFO”). We believe the FIFO method is preferable because it more closely matches the physical flow of materials through purchasing, receiving, warehousing, production and order fulfillment, it results in a more consistent method to value inventory across the Company, and it improves comparability with industry peers. This change increased Retained Earnings by $106.6 million as of January 1, 2023, and increased net income by $1.1 million and $4.2 million for the years ended December 31, 2023 and 2024, respectively. All prior amounts have been adjusted.

Financial Highlights

• Net sales decreased $146 million, or 3%, to $5,195 million in 2025 from $5,341 million in 2024.

• Operating income in 2025 was $1,042 million compared to $1,040 million in 2024.

• Net income in 2025 decreased to $806 million from $811 million in 2024.

• Diluted earnings per share was $22.79 per share in 2025 compared to $22.66 per share in 2024.

• We generated $758 million of cash flow from operating activities in 2025 compared to $946 million in 2024.

• We returned $173 million to shareholders through dividend payments and repurchased $482 million as part of our Share Repurchase Plans in 2025.

Recent Developments

On July 4, 2025, the One Big Beautiful Bill Act (the “OBBBA”) was enacted into law, introducing significant changes to corporate income tax rates and deductions. For fiscal year 2025, the OBBBA did not have a material impact on our effective tax rate. We continue to evaluate the future impact of the OBBBA for those provisions that are effective after fiscal year 2025.

Overview of Results

The Home Comfort Solutions segment experienced a 7% decrease in net sales and a $32 million decrease in segment profit in 2025 as compared to 2024 primarily driven by lower sales volumes. Our Building Climate Solutions segment saw an increase in net sales of 5% and a $33 million increase in segment profit in 2025 compared to 2024, primarily due to favorable price and mix.

Gross Profit

Gross profit margins for 2025 increased 10 basis points (“bps”) to 33.4% compared to 33.3% in 2024. Gross profit margin increased 290 bps from higher price and favorable mix, which was partially offset by 160 bps from higher products costs and 120 bps from higher freight and distribution costs.

Selling, General and Administrative Expenses

SG&A expenses decreased by $49 million in 2025 compared to 2024. As a percentage of net sales, SG&A expenses decreased 60 bps from 13.7% to 13.1% in the same periods, primarily due to lower employee-related costs including reduced incentive compensation and reduced discretionary expenses.

Losses and Other Expenses, Net

Losses and other expenses, net for 2025 and 2024 included the following (in millions):

For the Years Ended December 31,

Foreign currency exchange (gains) losses

Acquisition costs

Other operating loss

Environmental liabilities and special litigation charges

Losses and other expenses, net (pre-tax)

Foreign currency exchange gains increased in 2025 primarily due to changes in foreign exchange rates in our primary markets. Acquisition costs are related to the acquisition of Duro Dyne and Supco. The acquisition occurred in the fourth quarter

of 2025. The Environmental liabilities and special litigation charges in 2025 relate to estimated remediation costs at some of our facilities and outstanding legal settlements including asbestos. Refer to Note 5 in the Notes to the Consolidated Financial Statements for more information on litigation, including asbestos-related litigation, and environmental liabilities.

Investments over which we do not exercise control but have significant influence are accounted for using the equity method of accounting. Income from equity method investments was $6 million in 2025 as compared to $8 million in 2024.

Interest Expense, net

Net interest expense of $41 million in 2025 increased slightly from $39 million in 2024 primarily due to increased borrowings as a result of decreased cash flow.

Income Taxes

The income tax provision was $191 million in 2025 compared to $188 million in 2024, and the effective tax rate was 19.2% in 2025 compared to 18.8% in 2024. The 2025 and 2024 effective tax rates differ from the statutory rate of 21% primarily due to foreign taxes. Refer to Note 12 in the Notes to the Consolidated Financial Statements for more information on income taxes.

See Note 9 of the Notes to Consolidated Financial Statements for more information on our derivatives and Note 3 of the Notes to the Consolidated Financial Statements for more information on our segments and for a reconciliation of segment profit to operating income.

Liquidity and Capital Resources

Our working capital and capital expenditure requirements are generally met through internally generated funds, bank lines of credit and our commercial paper program. Working capital needs are generally greater in the first and second quarters due to the seasonal nature of our business cycle.

Statement of Cash Flows

The following table summarizes our cash flow activity for the years ended December 31, 2025, 2024 and 2023 (in millions):

Net cash provided by operating activities

Net cash used in investing activities

Net cash used in financing activities

Net Cash Provided By Operating Activities - Net cash provided by operating activities decreased $188 million to $758 million in 2025 compared to $946 million in 2024. The decrease was primarily attributable to an increase in net working capital of $217 million.

Net Cash Used In Investing Activities - Net cash used in investing activities increased $481 million from 2024 to 2025 primarily due to $545 million related to our acquisition of Duro Dyne and Supco, which was partially offset by lower capital expenditures. Capital expenditures were $119 million, $164 million and $250 million in 2025, 2024 and 2023, respectively. Capital expenditures in 2025 were primarily related to the expansion of our manufacturing capacity equipment and investments in systems and software to support the overall enterprise.

Net Cash Used In Financing Activities - Net cash used in financing activities was $466 million in 2025 and $419 million in 2024. The increase was primarily due to share repurchases in 2025, offset by higher net debt borrowings. We repurchased $482 million and $54 million in 2025 and 2024, respectively, as part of our Share Repurchase Plans. There were no repurchases in 2023. We also returned $173 million to shareholders through dividend payments in 2025.

Commercial Paper Program

On October 25, 2023, we established a commercial paper program (the “Program”), as a replacement to our Asset Securitization Program which expired in November 2023, pursuant to which we may issue short-term, unsecured commercial paper notes (the “CP Notes”) under the exemption from registration contained in Section 4(a)(2) of the Securities Act. Amounts available under the Program may be borrowed, repaid, and re-borrowed from time to time, with the aggregate face or principal amount of the CP Notes outstanding under the Program at any time not to exceed $500.0 million. The CP Notes have maturities of up to 397 days from the date of issue and rank pari passu with all of our other unsecured and unsubordinated indebtedness. The net proceeds from issuances of the CP Notes are typically used for general corporate purposes. Our revolving credit facility serves as a liquidity backstop for the repayment of CP Notes outstanding under the Program. There are $226.0 million in CP Notes outstanding under the Program as of December 31, 2025.

Credit Agreement

On May 9, 2025, we entered into an Amendment and Restatement Agreement (the “Credit Agreement”) to our existing unsecured revolving credit facility with JPMorgan Chase Bank, N.A., as administrative agent, and the other lenders party thereto. Our Credit Agreement consists of a $1.0 billion unsecured revolving credit facility with an option to increase the revolving commitments by up to $350 million at our request, subject to the terms and conditions of the Credit Agreement. We had no outstanding borrowings as well as $1.7 million committed to standby letters of credit as of December 31, 2025. Subject to covenant limitations, $772.3 million was available for future borrowings after taking into consideration outstanding borrowings under the Program. The Credit Agreement includes a subfacility for swingline loans of up to $65.0 million. The Credit Agreement will expire and outstanding loans will be required to be repaid in May 2030, unless maturity is extended by the lenders pursuant to two one-year extension options that we may request under the Credit Agreement.

Term Loan

On October 16, 2025, we entered into a Term Credit Agreement (the “Term Credit Agreement”) with Wells Fargo Bank, National Association, as administrative agent, and the other lenders party thereto. We borrowed $300.0 million pursuant to the Term Credit Agreement and used the net proceeds to repay existing borrowings under the Credit Agreement. The Term Credit Agreement matures on October 16, 2027. Loans under the Term Credit Agreement bear interest at our election at a rate per annum equal to (i) a forward-looking term rate based on the secured overnight financing rate for the applicable interest period ("Term SOFR"), plus an applicable margin ranging between 0.90% and 1.025% per annum depending on our long-term unsecured debt rating, or (ii) the highest of the Wells Fargo Bank, National Association prime rate, the Federal Funds rate plus

0.50%, and Term SOFR for a one month tenor in effect on such day plus 1.00%, plus an applicable margin ranging between 0.00% and 0.025% per annum depending on our long-term unsecured debt rating.

The Term Credit Agreement contains customary covenants and events of default that are substantially similar to the existing covenants and events of default in our Credit Agreement.

Senior Unsecured Notes

In September 2023, we issued $500.0 million of senior unsecured notes, which will mature in September 2028 (the "2028 Notes") with interest being paid semi-annually in March and September at 5.50%. In July 2020, we issued senior unsecured notes for $300.0 million, which will mature on August 1, 2027 (the "2027 Notes" and collectively with the 2028 Notes, the "Notes") with interest being paid semi-annually in February and August at 1.70% per annum. On August 1, 2025, we repaid upon maturity $300.0 million of our 1.35% senior unsecured notes due in 2025 that were originally issued in 2020.

Financial Leverage

We periodically review our capital structure, including our primary bank facility, to ensure the appropriate levels of liquidity and leverage and to take advantage of favorable interest rate environments or other market conditions. We consider various other financing alternatives and may, from time to time, access the capital markets.

We also evaluate our debt-to-capital and debt-to-EBITDA ratios to determine, among other considerations, the appropriate targets for c apital expenditures and share repurchases under our Share Repurchase Plans. Our book value of debt-to-total-capital ratio decreased to 54% at December 31, 2025 compared to 57% at December 31, 2024.

As of December 31, 2025, our senior credit ratings were Baa1 with a stable outlook, and BBB with a stable outlook, by Moody’s Investors Service, Inc. (“Moody’s”) and Standard & Poor’s Rating Group (“S&P”), respectively. The security ratings are not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time by the assigning rating agency. Each rating should be evaluated independently of any other rating. Our goal is to maintain investment grade ratings from Moody’s and S&P to help ensure the capital markets remain available to us.

Liquidity

We believe our cash and cash equivalents of $34.2 million, future cash generated from operations and available future borrowings are sufficient to fund our operations, planned capital expenditures, future contractual obligations, share repurchases, anticipated dividends and other needs in the foreseeable future. Included in our cash and cash equivalents as of December 31, 2025 was $9 million of cash held in foreign locations, although that amount can fluctuate significantly depending on the timing of cash receipts and payments. Our cash and cash equivalents held in foreign locations is generally available for use in our U.S. operations and could be subject to foreign withholding taxes and U.S. state taxes.

No contributions are required to be made to our U.S. defined benefit plans in 2026. We made $7.6 million in total contributions to our pension plans in 2025.

Dividend payments were $173 million in 2025 compared to $160 million in 2024. On May 22, 2025, our Board of Directors approved a 13% increase in our quarterly dividend on common stock from $1.15 to $1.30 per share effective with the July 2025 dividend payment.

Delaware law limits the ability to pay dividends to surplus or, if there is no surplus, out of net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. In addition, stock repurchases can only be made out of surplus and only if our capital would not be impaired.

We expect capital expenditures of approximately $250 million in 2026 for general capital improvement projects .

Financial Covenants related to our Debt

The Credit Agreement and Term Credit Agreement (the “Credit Facilities”) are guaranteed by the Guarantor Subsidiaries (as defined below) and contain customary covenants applicable to us and our subsidiaries including limitations on indebtedness, liens, dividends, stock repurchases, mergers and sales of all or substantially all of our assets. In addition, the Credit Facilities each contain a financial covenant requiring us to maintain, as of the last day of each fiscal quarter for the four prior fiscal

quarters, a Total Net Leverage Ratio of no more than 3.50 to 1.00 (or, at our election, on up to two occasions following a material acquisition, 4.00 to 1.00).

Our Credit Facilities contains customary events of default. These events of default include nonpayment of principal or other amounts, material inaccuracy of representations and warranties, breach of covenants, default on certain other indebtedness or receivables securitizations (cross default), certain voluntary and involuntary bankruptcy events and the occurrence of a change in control. A cross default under our Credit Facilities could occur if:

• We fail to pay any principal or interest when due on any other indebtedness or receivables securitization exceeding $75.0 million; or

• We are in default in the performance of, or compliance with any term of any other indebtedness in an aggregate principal amount exceeding $75.0 million, or any other condition exists which would give the holders the right to declare such indebtedness due and payable prior to its stated maturity.

Each of our major debt agreements contains provisions by which a default under one agreement causes a default in the others (a cross default). If a cross default under our Credit Facilities or our senior unsecured notes were to occur, it could have a wider impact on our liquidity than might otherwise occur from a default of a single debt instrument or lease commitment.

If any event of default occurs and is continuing, the administrative agent, or lenders with a majority of the aggregate commitments, may require the administrative agent to terminate our right to borrow under our Credit Agreement and accelerate amounts due under our Credit Facilities (except for a bankruptcy event of default, in which case such amounts will automatically become due and payable and the lenders’ commitments will automatically terminate).

In the event of a credit rating downgrade below investment grade resulting from a change of control, holders of our senior unsecured notes will have the right to require us to repurchase all or a portion of the senior unsecured notes at a repurchase price equal to 101% of the principal amount of the notes, plus accrued and unpaid interest, if any. The notes are guaranteed, on a senior unsecured basis, by the Guarantor Subsidiaries. The indenture governing the notes contains covenants that, among other things, limit our ability and the ability of the subsidiary guarantors to: create or incur certain liens; enter into certain sale and leaseback transactions; and enter into certain mergers, consolidations and transfers of substantially all of our assets. The indenture also contains a cross default provision which is triggered if we default on other debt of at least $75 million in principal which is then accelerated, and such acceleration is not rescinded within 30 days of the notice date.

We are currently in compliance with all covenant requirements.

Leasing Commitments

Refer to Note 5 in the Notes to the Consolidated Financial Statements for more details on our leasing commitments.

Guarantees related to our Debt Obligations

Our senior unsecured notes were issued by Lennox International Inc. (the “Parent”) and are unconditionally guaranteed by certain of our subsidiaries (the “Guarantor Subsidiaries”) and are not secured by our other subsidiaries. The Guarantor Subsidiaries are 100% owned and consolidated, all guarantees are full and unconditional, and all guarantees are joint and several.

The following combined Parent and Guarantor Subsidiaries financial information is presented as of December 31, 2025 and for the year ended December 31, 2025 (in millions):

Off Balance Sheet Arrangements

We have no off-balance sheet arrangements that we believe may have a material current or future effect on our financial condition, liquidity or results of operations.

Contractual Obligations

Contractual obligations arise in the normal course of business and include debt and related interest payments, leases, purchase obligations, pension and post-retirement benefits and warranty liabilities. For additional information regarding our contractual obligations, see Note 5 of the Notes to the Consolidated Financial Statements. See Note 10 of the Notes to the Consolidated Financial Statements for more information on our pension and post-retirement benefits obligations. See Note 13 of the Notes to the Consolidated Financial Statements for more information on our debt obligations.

Fair Value Measurements

Fair value is the price that would be received to sell an asset or the price paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date and requires consideration of our creditworthiness when valuing certain liabilities. Our framework for measuring fair value is based on a three-level hierarchy for fair value measurements.

The three-level fair value hierarchy for disclosure of fair value measurements is defined as follows:

Level 1 - Quoted prices for identical instruments in active markets at the measurement date.

Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets at the measurement date and for the anticipated term of the instrument.

Level 3 - Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.

Where available, the fair values were based upon quoted prices in active markets. However, if quoted prices were not available, then the fair values were based upon quoted prices for similar assets or liabilities or independently sourced market parameters, such as credit default swap spreads, yield curves, reported trades, broker/dealer quotes, interest rates and benchmark securities. For assets and liabilities without observable market activity, if any, the fair values were based upon discounted cash flow methodologies incorporating assumptions that, in our judgment, reflect the assumptions a marketplace participant would use. Valuation adjustments to reflect either party’s creditworthiness and ability to pay were incorporated into our valuations, where appropriate, as of December 31, 2025 and 2024, the measurement dates. See Note 16 of the Notes to the Consolidated Financial Statements for more information on the assets and liabilities measured at fair value.

Market Risk

Commodity Price Risk

We enter into commodity futures contracts to stabilize prices expected to be paid for raw materials and parts containing high copper and aluminum content. These contracts are for quantities equal to or less than quantities expected to be consumed in future production. Fluctuations in metal commodity prices impact the value of the futures contracts that we hold. When metal commodity prices rise, the fair value of our futures contracts increases. Conversely, when commodity prices fall, the fair value of our futures contracts decreases. Information about our exposure to metal commodity price market risks and a sensitivity analysis related to our metal commodity hedges is presented below (in millions):

Notional amount (pounds of aluminum and copper)

Carrying amount and fair value of net asset

Change in fair value from 10% change in forward prices

Refer to Note 9 of the Notes to the Consolidated Financial Statements for additional information regarding our commodity futures contracts.

Interest Rate Risk

Our results of operations can be affected by changes in interest rates due to variable rates of interest on our debt facilities, cash, cash equivalents and short-term investments. A 10% adverse movement in the levels of interest rates across the entire yield curve would have resulted in an increase to pre-tax interest expense of approximately $1.1 million, $0.9 million and $2.3 million for the years ended December 31, 2025, 2024 and 2023, respectively.

From time to time, we may use an interest rate swap hedging strategy to eliminate the variability of cash flows in a portion of our interest payments. This strategy, when employed, allows us to fix a portion of our interest payments when interest rates are low. As of December 31, 2025 and 2024, no interest rate swaps were in effect.

Foreign Currency Exchange Rate Risk

Our results of operations are affected by changes in foreign currency exchange rates. Net sales and expenses in foreign currencies are translated into U.S. dollars for financial reporting purposes based on the average exchange rate for the period. Our primary exposure to foreign currencies are the Canadian dollar, Mexican Peso, and the Euro. During 2025, 2024 and 2023, net sales from outside the U.S. represented 7%, 6% and 11%, respectively, of our total net sales. For the years ended December 31, 2025, 2024, and 2023, foreign currency transaction gains and losses did not have a material impact to our results of operations. A 10% change in foreign exchange rates would have had an estimated $5.8 million, $2.6 million and $5.6 million impact to net income for the years ended December 31, 2025, 2024 and 2023, respectively.

We seek to mitigate the impact of currency exchange rate movements on certain short-term transactions by periodically entering into foreign currency forward contracts. By entering into forward contracts, we lock in exchange rates that would otherwise cause losses should the U.S. dollar appreciate and gains should the U.S. dollar depreciate. Refer to Note 9 of the Notes to the Consolidated Financial Statements for additional information regarding our foreign currency forward contracts.

Critical Accounting Estimates

A critical accounting estimate is one that requires difficult, subjective or complex estimates and assessments and is fundamental to our results of operations and financial condition. The following describes our critical accounting estimate related to product warranties and product-related contingencies and how we develop our judgments, assumptions and estimates about future events and how such policies can impact our financial statements. This discussion and analysis should be read in conjunction with our Consolidated Financial Statements and related Notes in “Item 8. Financial Statements and Supplementary Data.”

Product Warranties and Product-Related Contingencies

The estimate of our liability for future warranty costs requires us to make assumptions about the amount, timing and nature of future product-related costs. Some of the warranties we issue extend 10 years or more in duration and a relatively small adjustment to an assumption may have a significant impact on our overall liability.

From time to time, we may also incur costs to repair or replace installed products experiencing quality issues in order to satisfy our customers and protect our brand. These product-related costs may not be covered under our warranties and are not covered by insurance.

We periodically review the assumptions used to determine the liabilities for product warranties and product-related contingencies and we adjust our assumptions based upon factors such as actual failure rates and cost experience. Numerous factors could affect actual failure rates and cost experience, including the amount and timing of new product introductions, changes in manufacturing techniques or locations, components or suppliers used. Should actual costs differ from our estimates, we may be required to adjust the liabilities and to record expense in future periods. See Note 5 in the Notes to the Consolidated Financial Statements for more information on our product warranties and product-related contingencies.
