**PART 1** 

**<u>ITEM 1 – BUSINESS</u>**

As used in this annual report on Form 10-K, references to the "Company," "A. O. Smith," "AOS," "we," "us," and "our" refer to A. O. Smith and its consolidated subsidiaries. The following discussion should be read in conjunction with our consolidated financial statements and notes thereto under "Item 8 Financial Statements and Supplementary Data" in this annual report on Form 10-K. Our company is comprised of two reporting segments: North America and Rest of World. Both segments manufacture and market comprehensive lines of residential and commercial gas and electric water heaters, boilers, heat pumps, tanks and water treatment products. Both segments primarily manufacture and market in their respective regions of the world. Our Rest of World segment is primarily comprised of China, India, and Europe.

***NORTH AMERICA***

Sales in our North America segment accounted for approximately 78 percent of our total sales in 2025. This segment serves residential and commercial end markets with a broad range of products including:

*Water heaters*. Our residential and commercial water heaters primarily come in sizes ranging from 40 to 80 gallon models. However, we also offer sizes as low as 2.5 gallon (point-of-use) and as high as 2,500 gallon products with varying efficiency ranges. We offer electric, natural gas and liquid propane tank-type models as well as tankless (gas and electric), heat pump and solar tank units. Typical applications for our water heaters include residences, restaurants, hotels, office buildings, laundries, car washes, schools and small businesses.

*Boilers.* Our residential and commercial boilers range in size from 45,000 British Thermal Units (BTUs) to 6.0 million BTUs. Boilers are closed loop water heating systems used primarily for space heating or hydronic heating. Our boilers are primarily used in applications in commercial settings for hospitals, schools, hotels and other large commercial buildings while residential boilers are used in homes, apartments and condominiums.

*Water treatment products.* Our water treatment products range from point-of-entry water softeners, solutions for problem well water, whole-home water filtration products and point-of-use carbon and reverse osmosis products. We also offer a comprehensive line of commercial water treatment and filtration products. Typical applications for our water treatment products include residences, restaurants, schools and offices.

*Other.* In our North America segment, we also manufacture expansion tanks, commercial solar water heating systems, swimming pool and spa heaters, related products and parts.

A significant portion of our North America sales is derived from the replacement of existing products.

We believe we are the largest manufacturer and marketer of water heaters in North America with a leading share in both the residential and commercial portions of the market. In the commercial segments of the market for both water heating and space heating, we believe our comprehensive product lines and our high-efficiency products give us a competitive advantage. Our wholesale distribution channel, where we sell our products primarily under the A. O. Smith and State brands, includes approximately 800 independent wholesale plumbing distributors serving residential and commercial end markets. We also sell our residential water heaters through the retail and maintenance, repair and operations (MRO) channels. In the retail channel, our customers include four of the six largest national hardware and home center chains, including a long-standing exclusive relationship with Lowe's where we sell A. O. Smith branded products.

Our Lochinvar brand is one of the leading residential and commercial boiler brands in North America. Approximately 45 percent of Lochinvar branded sales consist of residential and commercial water heaters while the remaining 55 percent of Lochinvar branded sales consist primarily of boilers and related parts. Our commercial boiler distribution channel is primarily comprised of manufacturer representative firms with the remainder of our Lochinvar branded products being distributed through wholesale channels.

In our water treatment business we sell through a variety of channels. We sell our A. O. Smith branded water treatment products primarily through our water quality dealer network and Amazon. Our Aquasana branded products are primarily sold directly to consumers through e-commerce channels. Our water softener products and problem well water solutions, which include the Hague, Water-Right, Master Water, Atlantic Filter, Impact, and Water Tec brands, are sold through water quality dealers and contractors. Our water softener and undersink filter products are also sold through regional home center retail chains.

Our energy-efficient product offerings continue to be a sales driver for our business. Our condensing commercial water heaters and boilers continue to be an option for commercial customers looking for high-efficiency water and space heating with a short payback period through energy savings. We offer residential heat pumps, condensing tank-type and tankless

**<u>[**Table of Contents**](#i1de722994910418ea076e2893b84ba6c_7)</u>**

water heaters in North America, as well as other higher efficiency water heating solutions to round out our energy-efficient product offerings. In 2024, we launched our newly designed ADAPT condensing gas tankless water heater and VERITUS air source commercial heat pump water heater to align with greenhouse gas emission reduction trends across the U.S. The VERITUS and ADAPT model lines were further expanded in 2025. We also recently launched our Cyclone Flex commercial condensing water heater with advanced features ahead of the upcoming October 2026 Department of Energy (DOE) commercial rule that will require all commercial water heaters to be condensing.

We sell our products in highly competitive markets. We compete in each of our targeted market segments based on product design, reliability, quality of products and services, advanced technologies, energy efficiency, maintenance costs and price. Our principal water heating and boiler competitors in North America include Rheem, Bradford White, Rinnai, Aerco and Navien. Numerous other manufacturing companies also compete. Our principal water treatment competitors in the U.S. are Culligan, Kinetico, Pentair, Franklin Electric and Ecowater as well as numerous regional assemblers.

***REST OF WORLD***

Sales in our Rest of World segment accounted for approximately 22 percent of our total sales in 2025, a majority of which were in China. We have operated in China for 30 years. In that time, we have established A. O. Smith brand recognition in the residential and commercial markets. We manufacture and market residential water heater and water treatment products, primarily incorporating reverse osmosis technology, and commercial dispensing water treatment products. The Chinese water heater market is predominantly comprised of electric wall-hung, gas tankless, combi-boiler, heat pump and solar water heaters. We believe we are one of the market leaders of water heaters and reverse osmosis water treatment products to the residential market in China in dollar terms. We also design and market kitchen products (range hoods, cooktops, steam ovens, and dishwashers) and connected product technology in China.

We sell our products in approximately 8,700 points of sale in China, of which approximately 3,800 are retail outlets in tier one through tier three cities and approximately 1,400 exclusively sell our products. We also sell our products through e-commerce channels. Our primary competitors in China in the water heater market segment are Haier/Casarte, Midea/COLMO, and Rinnai. Our principal competitors in the water treatment market are Angel, Haier/Casarte, Midea/COLMO, and Truliva. In the third quarter of 2025, we initiated an assessment of strategic opportunities for our China business, including strategic partnerships and other alternatives. We believe the China market has substantial long-term prospects and are committed to realizing the potential upside inherent in our China business

In 2008, we established a sales office in India and began importing products specifically designed for India. We began manufacturing water heaters in India in 2010 and water treatment products in 2015. In 2024, we expanded our product offerings and geographic footprint with the acquisition of Pureit, formerly a Unilever PLC business. Pureit offers a broad range of residential water purification solutions in India and other South Asian markets. We continue to increase our product offerings and sales in India, primarily through wholesale, e-commerce and retail channels. Our primary competitors in India are Racold, Bajaj and Havells in the water heater market and Eureka Forbes and Kent in the water treatment market. We also sell water heaters in the European, Middle East, and Far East markets and water treatment products in Vietnam, all of which combined comprised less than 22 percent of total Rest of World sales in 2025.

**RAW MATERIALS** 

Raw materials for our manufacturing operations, primarily consisting of steel, are generally available in adequate quantities. A portion of our customers are contractually obligated to accept price changes based on fluctuations in steel prices. There has been volatility in steel costs over the last several years. In addition, tariffs have increased volatility in input materials.

**BACKLOG** 

Due to the short-cycle nature of our businesses, our operations do not normally sustain significant backlogs.

**RESEARCH AND DEVELOPMENT** 

To improve our competitiveness by generating new products and processes, we conduct research and development at our Corporate Technology Center in Milwaukee, Wisconsin, our Global Engineering Center in Nanjing, China, and our operating locations. Our total expenditures for research and development in 2025, 2024 and 2023 were $95.0 million, $101.7 million and $97.5 million, respectively.

**PATENTS AND TRADEMARKS** 

We invest, own and use in our businesses various trademarks, trade names, patents, trade secrets and licenses. We monitor our intellectual property for infringements. Although we believe our trademarks, trade names, patents, trade secrets, and licenses to constitute a valuable asset in the aggregate, we do not regard our business as being materially dependent on any single trademark, trade name, patent, trade secret, license or any group of related such rights. Our trade name is important with respect to our products, particularly in China, India, and North America.

**HUMAN CAPITAL** 

We employed approximately 11,500 employees as of December 31, 2025 with approximately 6,500 in North America and 5,000 in Rest of World. A small portion of our workforce in the U.S. is represented by a labor union, while outside the U.S., we have employees in certain countries that are represented by employee representative organizations, such as an employee association, union, or works council.

*Our Guiding Principles and Values*. The foundation of how we conduct business and interact with our employees is outlined in A. O. Smith Corporation's Guiding Principles and our Statement of Values. These principles and values help to shape how we hire, train and treat our employees, emphasizing teamwork and promoting diversity in seeking our objectives. We believe that our Guiding Principles and Values shape the critical elements of our effort to attract, retain and develop talent. In 2025, we were named by Ethisphere on the list of the World's Most Ethical Companies for a second consecutive year. The annual list recognizes global companies dedicated to integrity, sustainability, governance, and community with a commitment to ethical behavior, accountability, and driving positive change. As reflected in our Guiding Principles, we strive to create a workplace where people from all backgrounds can thrive and achieve their fullest potential. Our commitment to this objective starts at the top with our Board of Directors, which is 40 percent diverse from either a gender or ethnic/racial perspective.

*Culture and Employee Engagement.* We conduct a Global Employee Engagement Survey on a biannual basis. This third party managed survey measures employees' level of engagement against external norms and provides us with actionable feedback that drives improvement priorities. Participation in our most recent survey in 2024 was 93 percent, which we believe reflects our employees' desire to share their perspectives and a commitment to continuous improvement. Survey results help shape action plans to further improve our culture and we will conduct the survey again in 2026.

*Compensation and Benefits.* We provide what we believe is a robust total compensation program designed to be market-competitive and internally equitable to attract, retain, motivate and reward a high-performance workforce. Regular internal and external analysis is performed to ensure there is market alignment. In addition to salaries, these programs, which vary by country, can include annual performance-based bonuses, stock-based compensation awards, retirement plans with employee matching opportunities, health benefits, health savings and flexible spending accounts, paid time off, family leave, and tuition assistance, among others.

*Training and Development.* We provide all employees with a wide range of professional development experiences, both formal and informal, to help them achieve their full potential. All of our salaried employees are given formal development plans. Some of the formal development programs that employees have access to include early-career leadership development programs, front-line leadership development programs, continuous improvement skill-building programs, core process technology councils and tuition reimbursement for degree programs or trade schools. To maintain our focus on career development all our salaried employees worldwide are required to have career conversations with their manager. Globally, all office and professional employees also have formal performance reviews and development plans with a focus on learning by doing. We expect our managers to work closely with their employees to ensure performance feedback and to conduct development discussions on a regular basis.

*Safety.* The safety of our people is always at the forefront of what we do. We provide safety training in our production facilities, designed to empower our employees with the knowledge and tools they need to make safe choices and mitigate risks. In addition to traditional training, we use standardized signage and visual management throughout our facilities. Since 1954, we have annually awarded the Lloyd B. Smith President's Safety Award, which acknowledges an A. O. Smith facility that demonstrates the most improvement over one year in the area of workplace safety.

**GOVERNMENT REGULATIONS AND ENVIRONMENTAL MATTERS** 

Our operations, including the manufacture, packaging, labeling, storage, distribution, advertising and sale of our products, are subject to various federal, state, local and foreign laws and regulations. In the U.S., many of our products are regulated by the Department of Energy, the Consumer Product Safety Commission, and the Federal Trade Commission. State and local governments, through laws, regulations, and building codes, also regulate our water heating and water treatment products. Whether at the federal, state, or local level, these laws are intended to improve energy efficiency and product safety, and protect public health and the environment. In recent years, a number of states and local authorities have proposed or implemented bans on gas-fired products in new construction in an effort to address greenhouse gas emissions. Similar laws and regulations have been adopted by government authorities in other countries in which we manufacture, distribute, and sell our products. We offer a complete line of water and hydronic heating products, including electric-powered water heaters and boilers, and we believe that any reduction in fossil fuel-powered products would be counterbalanced by a corresponding increase in demand for our non-fossil fuel powered products. We are confident that our continued emphasis on product design and innovation, including energy efficiency, will keep us well positioned to deliver products demanded by customers, regardless of fuel source.

In addition, our operations are subject to federal, state and local environmental laws. We are subject to regulations of the U.S. Environmental Protection Agency and the Occupational Health and Safety Administration and their counterpart state agencies. Compliance with government regulations and environmental laws has not had and is not expected to have a material effect upon the capital expenditures, earnings, or competitive position of our company. See Item 3.

**<u>ITEM 1A – RISK FACTORS</u>**

In the ordinary course of our business, we face various strategic, operating, compliance and financial risks. These risks could have an impact on our business, financial condition, operating results and cash flows. The risks set forth below are not an exhaustive list of potential risks but reflect those that we believe to be material. You should carefully consider the risk factors set forth below and all other information contained in this Annual Report on Form 10-K, including the documents incorporated by reference, before making an investment decision regarding our common stock. If any of the events contemplated by the following risks were to actually occur, then our business, financial condition, or results of operations could be materially adversely affected. As a result, the trading price of our common stock could decline, and you may lose all or part of your investment.

**Economic and Industry Risks**

*■The effects of global and regional economic conditions could have a material adverse effect on our business*

A decline in economic activity, such as a recession or economic downturn, in the U.S., China, and other regions in the world in which we do business, could further adversely affect consumer confidence and spending patterns which could result in decreased demand for the products we sell, a delay in purchases, increased price competition, or slower adoption of energy-efficient water heaters and boilers, or high-quality water treatment products, which could negatively impact our profitability and cash flows. Such deterioration in economic conditions could arise from many factors or fears including public health crises, further deterioration in the property market, political instability or risk of government default. In addition, an increase in price levels generally or in particular industries, could result in a consumer shift away from the products we offer, including electing to purchase lower priced models, which could adversely affect our revenues and, at the same time, increase our costs. A deterioration in economic conditions also could negatively impact our vendors and customers, which could result in an increase in bad debt expense, customer and vendor bankruptcies, interruption or delay in supply of materials, or increased material prices, which could negatively impact our ability to distribute, market and sell our products and our financial condition, results of operations and cash flows.

*■Import tariffs, taxes, customs duties and other trading regulations imposed by the U.S. government and retaliatory responses from other countries, could significantly increase the prices we pay for raw materials that are critical to our ability to manufacture our products* 

Import tariffs, taxes, customs duties and other trading regulations imposed by the U.S. government on foreign countries, or by foreign countries on the U.S., could significantly increase the prices we pay for raw materials that are critical to our ability to manufacture our products. In addition, we may be unable to find a domestic supplier to provide the necessary raw materials on an economical basis in the amounts we require. Also, the current U.S. administration has imposed new tariffs and raised the possibility of imposing additional new or increased tariffs. Any widespread imposition of additional new or increased tariffs could increase the cost of and reduce the demand for our products and any cost increases will require us to increase prices, foreclose our sales into impacted markets or negatively impact our profit margins. Any new or increased tariffs could also trigger retaliatory responses from other countries which may decrease the competitiveness of our products in foreign markets. New or increased tariffs could also negatively affect U.S. national or regional economies, which could negatively affect the demand for our products. Unfavorable changes to import tariffs, taxes, customs duties and other trading regulations could have a material adverse effect on our financial condition, results of operations and cash flows.

*■The occurrence or threat of extraordinary events, including natural disasters, political disruptions, terrorist attacks, public health issues, and acts of war, could significantly disrupt production, or impact consumer spending*

As a global company with a large international footprint, we are subject to increased risk of damage or disruption to us and our employees, facilities, suppliers, distributors, or customers. Extraordinary events, including natural disasters, resulting from but not limited to climate change, political disruptions, terrorist attacks, public health issues and acts of war may disrupt our business and operations and impact our supply chain and access to necessary raw materials or could adversely affect the economy generally, resulting in a loss of sales and customers. Any of these disruptions or other extraordinary events outside of our control that impact our operations or the operations of our suppliers and key distributors could affect our business negatively, harming operating results.

Natural disasters and extreme weather conditions may disrupt the productivity of our facilities. For example, two of our manufacturing plants are located within a floodplain that has experienced past flooding events. We also have other manufacturing facilities located in hurricane and earthquake zones. We maintain insurance coverage and have taken steps to mitigate physical risks related to natural disasters and extreme weather conditions. Although we have taken steps to mitigate

------

**<u>[**Table of Contents**](#i1de722994910418ea076e2893b84ba6c_7)</u>**

the risk of flooding, there is still the potential for natural disasters and extreme weather conditions to disrupt the productivity of our facilities.

Apart from the potential impact on our operations, these types of events also could negatively impact consumer spending in the impacted regions or depending on the severity, globally, which could materially and adversely affect our financial condition, results of operations and cash flows.

*■Because we participate in markets that are highly competitive, our revenues and earnings could decline as we respond to competition*

We sell all of our products in highly competitive and evolving markets. We compete in each of our targeted markets based on product design, reliability, quality of products and services, advanced technologies, product performance, maintenance costs and price. Some of our competitors may have greater financial, marketing, manufacturing, research and development and distribution resources than we have; others may invest little in technology or product development but compete on price and the rapid replication of features, benefits, and technologies, and some are increasingly expanding beyond their existing manufacturing or geographic footprints. New technologies and new competitors have developed and continue to develop in certain markets in which we participate, such as gas tankless and heat pump technologies in North America. While we design and manufacture these and other products, we cannot assure that our products will continue to compete successfully with those of our current competitors and new market participants and it is possible that we will not be able to retain our customer base or improve or maintain our profit margins on sales to our customers. There is also increasing use of data analytics, machine learning, and artificial intelligence software, which our competitors may be able to use more effectively or implement more successfully than we are able to do. Failure to adapt to the evolving competitive environment could materially and adversely affect our financial condition, results of operations and cash flows.

*■Our operations could be adversely impacted by material and component price volatility, as well as supplier concentration*

The market prices for certain materials and components we purchase, primarily steel, can be volatile. In recent years, we have also experienced inflation-related increases in our transportation and input costs. In addition tariffs could potentially increase volatility in prices of steel and other input materials. Significant increases in the cost of any of the key materials and components we purchase would increase our cost of doing business and ultimately could lead to lower operating earnings if we are not able to recover these cost increases through price increases to our customers. Historically, there has been a lag in our ability to recover increased material costs from customers, and that lag, could negatively impact our profitability. In some cases, we are dependent on a limited number of suppliers for some of the raw materials and components we require in the manufacturing of our products. A significant disruption or termination of the supply from one of these suppliers could delay sales or increase costs which could result in a material adverse effect on our financial condition, results of operations and cash flows.

*■Our business could be adversely impacted by changes in consumer purchasing behavior, consumer preferences, technological changes, and market trends*

Consumer preferences for products and the methods in which they purchase products are constantly changing based on, among other factors, cost, performance, convenience, availability of government incentives, environmental and social concerns and perceptions. As consumer confidence changes, purchasing behavior may shift the product mix to lower priced models in the markets in which we participate or result in a shift to other distribution channels, for example e-commerce. Consumer preferences and broader trends, such as decarbonization and electrification efforts in response to climate change, may result in reduced demand for gas or fossil fuel-powered products and increased demand for higher efficiency products and/or more electric powered products. In addition, technologies are ever changing. Our ability to respond to these trends, timely transition our product portfolio, develop new and innovative products, and acquire and protect the necessary intellectual property rights is essential to our continued success, but cannot reasonably be assured. It is possible that we will not be able to develop new technologies, products or distribution channels, or do so on a timely basis, to align with consumer purchasing behavior and consumer preferences, which could materially and adversely affect our financial condition, results of operations and cash flows.

■*Because approximately 18 percent of our sales in 2025 were attributable to China, adverse economic conditions or changes in consumer behavior in China could impact our business*

Our third-party sales in China decreased twelve percent in local currency in 2025 compared to 2024. We derive a substantial portion of our sales in China from premium-tier products. Changes in consumer preferences and purchasing behaviors including preferences for e-commerce and manufacturer emphasis on brand ecosystems and connectivity, weakening

------

**<u>[**Table of Contents**](#i1de722994910418ea076e2893b84ba6c_7)</u>**

consumer confidence and sentiment, as well as economic uncertainty, sociopolitical and demographic risks, availability of government incentives, and increased competition from Chinese-based companies may prompt Chinese consumers to postpone purchases, choose lower-priced products or different alternatives, or lengthen the cycle of replacement purchases. Further deterioration in the Chinese economy may adversely affect our financial condition, results of operations and cash flows.

In 2025, we announced a strategic assessment of our China business. This may lead to uncertain outcomes, costs, and impacts that could negatively affect the company. The announcement might also cause uncertainty among employees, customers, suppliers, and investors that could have a material adverse effect on our financial position, results of operations and cash flows.

**Business, Operational, and Strategic Risks**

*■We sell our products and operate outside the U.S., and to a lesser extent, rely on imports and exports, which may present additional risks to our business* 

Approximately 31 percent of our sales in 2025 were attributable to products sold outside of the U.S., primarily in China and Canada, and to a lesser extent in India and Europe. We also have operations and business relationships outside the U.S. that comprise a portion of our manufacturing, supply, and distribution. Approximately 4,200 of our 11,500 employees as of December 31, 2025 were located in China. At December 31, 2025, approximately $140 million of cash and marketable securities were held by our foreign subsidiaries, substantially all of which were located in China. International operations generally are subject to various risks, including: political, religious, and economic instability; local labor market conditions; new or increased tariffs or other trade restrictions, or changes to trade agreements; the impact of foreign government regulations, actions or policies; the effects of income taxes; governmental expropriation; the changes or imposition of statutory restrictions which prohibit repatriation of cash; the imposition or increases in withholding and other taxes on remittances and other payments by foreign subsidiaries; labor relations problems; the imposition of environmental or employment laws, or other restrictions or actions by foreign governments; and differences in business practices.

Unfavorable changes in the political, regulatory, or trade climate, diplomatic relations, or government policies, particularly in relation to countries where we have a presence, including Canada, China, India and Mexico, could have a material adverse effect on our financial condition, results of operations and cash flows or our ability to repatriate funds to the U.S.

*■A material loss, cancellation, reduction, or delay in purchases by one or more of our largest customers could harm our business*

Sales to our five largest customers represented approximately 41 percent of our sales in 2025. We expect that our customer concentration will continue for the foreseeable future. Our concentration of sales to a relatively small number of customers makes our relationships with each of these customers important to our business. We cannot assure that we will be able to retain our largest customers. Some of our customers may shift their purchases to our competitors in the future. Our customers may experience financial instability, affecting their ability to make or pay for future purchases. Further, a customer may be acquired by a customer of a competitor which could result in our loss of that customer. The loss of one or more of our largest customers, any material reduction or delay in sales to these customers, or our inability to successfully develop relationships with additional customers could have a material adverse effect on our financial position, results of operations and cash flows.

*■A portion of our business could be adversely affected by a further decline in North American new residential or commercial construction or a decline in replacement-related volume of water heaters and boilers, including a decline in demand for commercial spaces*

Residential new construction activity in North America declined in 2025 and industry-wide replacement-related volume of water heaters was flat compared to 2024. New residential housing starts in the U.S. are projected to be approximately flat and housing completions are expected to decrease in 2026 compared to 2025. Commercial construction activity in North America grew in 2025. We believe that the significant majority of the markets we serve are for the replacement of existing products, and residential water heater replacement volume has been strong. In recent years, businesses and commercial spaces have experienced and may experience in the future, fluctuation in demand and in occupancy that may reduce demand for our products, and commercial sectors, such as the restaurant and hospitality industries in which we have customers, may experience long-term shifts in consumer behavior which could negatively impact demand or capacity. In addition, the acceptance of remote work arrangements could negatively impact demand for commercial construction. Changes in the replacement volume and in the construction market in North America could negatively affect us.

*■An inability to adequately maintain our information systems and their security, as well as to protect data and other confidential information, could adversely affect our business and reputation*

In the ordinary course of business, we utilize information systems for day-to-day operations, to collect and store sensitive data and information, including our proprietary and regulated business information and personally identifiable information of our customers, suppliers and business partners, as well as personally identifiable information about our employees. Our information systems are susceptible to outages due to system failures, cybersecurity threats, failures on the part of third-party information system providers, natural disasters, power loss, telecommunications failures, viruses, fraud, theft, malicious actors or breaches of security. Like many companies, we, and some third parties upon which we rely, have experienced cybersecurity incidents and attacks on information technology networks and systems, products and services in the past but, to date, none have resulted in a material breach or had a material adverse impact on our financial condition, results of operations, or cash flows. We may experience such incidents and attacks in the future, potentially with increasing frequency from increasingly sophisticated cyber threats. In addition, remote work and remote access to our systems may heighten these risks. Use of artificial intelligence software may also create risks from unintentional disclosure of proprietary, confidential, personal or otherwise sensitive information. Although we have a response plan in place in the event of a data breach and we have an active program to maintain and improve data security and address these risks and uncertainties by implementing and improving internal controls, security technologies, insurance programs, network and data center resiliency and recovery processes, a successful attack in the future could result in operations failure or breach of security that could lead to disruptions of our business activities and the loss or disclosure of both our and our customers' financial, product and other confidential information and could result in regulatory actions, significant expense and litigation and have a material adverse effect on our financial condition, results of operations and cash flows and our reputation.

*■Our international operations are subject to risks related to foreign currencies*

We have a significant presence outside of the U.S., primarily in China and Canada and to a lesser extent India, Europe, and Mexico, and therefore, hold assets, including $83 million of cash and marketable securities denominated in Chinese renminbi, incur liabilities, earn revenues and pay expenses in a variety of currencies other than the U.S. dollar. The financial statements of our foreign subsidiaries are translated into U.S. dollars in our consolidated financial statements. Furthermore, typically our products are priced in foreign countries in local currencies. As a result, we are subject to risks associated with operating in foreign countries, including fluctuations in currency exchange rates and interest rates, or global exchange rate instability or volatility that strengthens the U.S. dollar against foreign currencies. An increase in the value of the U.S. dollar relative to the local currencies of our foreign markets, particularly in China, has negatively affected our sales, profitability, and cash and cash equivalents balances and could have such effects in the future. In addition to currency translation risks, we incur a currency transaction risk whenever one of our subsidiaries enters into a purchase or sale transaction using a currency different from the operating subsidiaries' functional currency. The majority of our foreign currency transaction risk results from sales of our products in Canada, a portion of which we manufacture in the U.S., and to a lesser extent from component purchases in India and Europe and payroll in Mexico. These risks may adversely impact our reported sales and profits in the future or negatively impact revenues and earnings translated from foreign currencies into U.S. dollars.

*■Our business may be adversely impacted by product defects*

Product defects can occur through our own product development, design and manufacturing processes or through our reliance on third parties for component design and manufacturing activities. We may incur various expenses related to product defects, including product warranty costs, product liability and recall or retrofit costs. While we maintain a reserve for product warranty costs based on certain estimates and our knowledge of current events and actions, our actual warranty costs may exceed our reserve, resulting in current period expenses and a need to increase our reserves for warranty charges. In addition, product defects and recalls may diminish the reputation of our brand. Further, our inability to cure a product defect could result in the failure of a product line or the temporary or permanent withdrawal from a product or market. Any of these events may have a material adverse impact on our financial condition, results of operations and cash flows.

*■Potential acquisitions could use a significant portion of our capital and we may not successfully integrate future acquisitions or operate them profitably or achieve strategic objectives*

Consistent with our stated strategic priorities, we will continue to evaluate potential acquisitions, and we could use a significant portion of our available capital to fund future acquisitions. We may not be able to successfully integrate future acquired businesses or operate them profitably or accomplish our strategic objectives for those acquisitions. If we complete any future acquisitions in new geographies, our unfamiliarity with relevant regulations and market conditions may impact our ability to operate them profitably or achieve our strategic objectives for those acquisitions. Our level of indebtedness may increase in the future if we finance acquisitions with debt, which would cause us to incur additional interest expense and

------

**<u>[**Table of Contents**](#i1de722994910418ea076e2893b84ba6c_7)</u>**

could increase our vulnerability to general adverse economic and industry conditions and limit our ability to service our debt or obtain additional financing. The impact of future acquisitions may have a material adverse effect on our financial condition, results of operations and cash flows.

**Legal, Regulatory, and Governance Risks**

■*Changes in regulations or standards, such as those associated with climate change, could adversely affect our business*

Our products are subject to a wide variety of statutory, regulatory, codes and industry standards and requirements related to, among other items, energy and water efficiency, environmental emissions, labeling and safety. For example, the U.S. Department of Energy (DOE) has adopted a new efficiency rule for commercial water heaters that will take effect in October 2026. The DOE has also adopted a new efficiency rule for our residential water heaters that will take effect in 2029, which seeks to rapidly increase market adoption of heat pump water heating technology. In addition, evolving national drinking water standards regulating per- and poly-fluoroalkyl substances (PFAS), as well as mandatory lead pipe replacements by public water utilities, could affect the demand for our water filtration products. There are also a number of foreign, federal, state and local governments adopting laws, regulations and codes in response to climate change that will require a mandatory transition to non-fossil fuel based sources of space and water heating equipment in the building sector. We believe our products are currently efficient, safe and environment-friendly. However, any further significant changes to regulatory or code requirements that require a transition to alternative energy sources as a replacement for gas, or significant shifts in industry standards, may substantially increase manufacturing costs, capital expenditures, transportation costs and raw material costs, alter distribution channels, attract new competitors, impact the size and timing of demand for our products, affect the types of products we are able to offer or put us at a competitive disadvantage, any of which could harm our business and have a material adverse effect on our financial condition, results of operations and cash flow.

*■We are subject to U.S. and global laws and regulations covering our domestic and international operations that could adversely affect our business and results of operations*

Due to our global operations, we are subject to many laws governing international relations, including those that prohibit improper payments to government officials and restrict where we can do business, what information or products we can supply to certain countries and what information we can provide to a non-U.S. government, including but not limited to the Foreign Corrupt Practices Act and the U.S. Export Administration Act. Violations of these laws may result in criminal penalties or sanctions that could have a material adverse effect on our financial condition, results of operations and cash flows.

■*Our sustainability commitments could result in additional costs, and our inability to achieve them could have an adverse impact on our reputation and performance*

We periodically communicate our strategies, commitments and targets related to sustainability matters, including carbon emissions, water usage, waste avoidance, and human rights, through the issuance of our sustainability report. Although we intend to meet these strategies, commitments and targets, and we are committed to advancing sustainable innovations in our industry, we may be unable to achieve them due to availability of resources, significant increases in operational costs, and technological changes. Failure to meet these sustainability requirements or targets could adversely impact our reputation as well as the demand for our products and adversely affect our business, financial condition and results of operations. In addition, standards and processes for measuring and reporting carbon emissions, water usage, waste avoidance, and other sustainability metrics may change over time, result in inconsistent data, or result in significant revisions to our strategies, commitments and targets, or our ability to achieve them. Any scrutiny of our carbon emissions or other sustainability disclosures or our failure to achieve related strategies, commitments and targets could negatively impact our reputation or performance.

*■Our results of operations may be negatively impacted by product liability lawsuits and claims*

Our products expose us to potential product liability risks that are inherent in the design, manufacture, sale and use of our products. While we currently maintain what we believe to be suitable product liability insurance, we cannot be certain that we will be able to maintain this insurance on acceptable terms, that this insurance will provide adequate protection against potential liabilities or that our insurance providers will be able to ultimately pay all insured losses. In addition, we self-insure a portion of product liability claims. A series of successful claims against us could materially and adversely affect our reputation and our financial condition, results of operations and cash flows.

*■We have significant goodwill and indefinite-lived intangible assets and an impairment of our goodwill or indefinite-lived intangible assets could cause a decline in our net worth*

Our total assets include significant goodwill and indefinite-lived intangible assets. Our goodwill results from our acquisitions, representing the excess of the purchase prices we paid over the fair value of the net tangible and intangible assets we acquired. We assess whether there have been impairments in the value of our goodwill or indefinite-lived intangible assets during the fourth quarter of each calendar year or sooner if triggering events warrant. If future operating performance at our businesses does not meet expectations, we may be required to reflect non-cash charges to operating results for goodwill or indefinite-lived intangible asset impairments. The recognition of an impairment of a significant portion of goodwill or indefinite-lived intangible assets would negatively affect our results of operations and total capitalization, the effect of which could be material. A significant reduction in our stockholders' equity due to an impairment of goodwill or indefinite-lived intangible assets may affect our ability to maintain the debt-to-capital ratio required under our existing debt arrangements. We have identified the valuation of goodwill and indefinite-lived intangible assets as a critical accounting policy. See "Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies - Goodwill and Indefinite-lived Intangible Assets" included in Item 7 of this Annual Report on Form 10-K.

*■Certain members of the founding family of our company and trusts for their benefit have the ability to influence all matters requiring stockholder approval*

We have two classes of common equity: our Common Stock and our Class A Common Stock. The holders of Common Stock currently are entitled, as a class, to elect only one-third of our Board of Directors. The holders of Class A Common Stock are entitled, as a class, to elect the remaining directors. Certain members of the founding family of our company and trusts for their benefit (Smith Family) have entered into a voting trust agreement with respect to shares of our Class A Common Stock and shares of our Common Stock they own. As of December 31, 2025, through the voting trust, these members of the Smith Family own approximately 67.8 percent of the total voting power of our outstanding shares of Class A Common Stock and Common Stock, taken together as a single class, and approximately 97.0 percent of the voting power of the outstanding shares of our Class A Common Stock, as a separate class. Due to the differences in the voting rights between shares of our Common Stock (one-tenth of one vote per share) and shares of our Class A Common Stock (one vote per share), the Smith Family voting trust is in a position to control to a large extent the outcome of matters requiring a stockholder vote, including the adoption of amendments to our certificate of incorporation or bylaws or approval of transactions involving a change of control. This ownership position may increase if other members of the Smith Family enter into the voting trust agreement, and the voting power relating to this ownership position may increase if shares of our Class A Common Stock held by stockholders who are not parties to the voting trust agreement are converted into shares of our Common Stock. The voting trust agreement provides that, in the event one of the parties to the voting trust agreement wants to withdraw from the trust or transfer any of its shares of our Class A Common Stock, such shares of our Class A Common Stock are automatically exchanged for shares of our Common Stock held by the trust to the extent available in the trust. In addition, the trust will have the right to purchase the shares of our Class A Common Stock and our Common Stock proposed to be withdrawn or transferred from the trust. As a result, the Smith Family members that are parties to the voting trust agreement have the ability to maintain their collective voting rights in our company even if certain members of the Smith Family decide to transfer their shares.

**<u>ITEM 1C – CYBERSECURITY</u>**

*Cybersecurity Governance*

We recognize the importance of maintaining the safety and security of our systems and data and have a holistic process for overseeing and managing cybersecurity and related risks. This process is supported by both our management and our Board of Directors.

Our Chief Digital and Information Officer (CDIO) oversees our information systems and cybersecurity function and reports to our Chief Executive Officer (CEO). He has over 30 years of experience in leading information systems management, strategy, and operational execution, including incident management, prevention, and response. Our Chief Information Security Officer (CISO) reports to our CDIO and is responsible for the protection and defense of our networks and systems and managing cybersecurity risk. He has over 20 years of experience in managing cybersecurity and related risks, including threat identification, incident response, and defense strategies. Our CDIO and CISO are supported by a direct and cross-functional team of professionals with broad experience and expertise in threat assessment and detection, mitigation technologies, training, incident response, and regulatory compliance.

Our Board of Directors is responsible for overseeing our enterprise risk management activities in general, which includes our management of information and cybersecurity risk. The full Board receives an update on our cyber risk management process and trends related to cybersecurity at least annually, or real-time if a material event occurs. The Audit Committee of the Board assists the full Board in its oversight of cybersecurity risks. As part of its oversight, the Audit Committee receives regular reports from management on information systems and security, including metrics and controls at each meeting, and other items at least annually including risk assessments, security software, incident response plans, and key updates to the cybersecurity program and its effectiveness.

We have also established a committee of our executive leadership team to consider cybersecurity risks and to consider mitigation strategies in managing the risks. Our CDIO and CISO participate on this committee, which meets regularly. We have an established incident response plan led by our CDIO and CISO to assess, respond, and report in the event of a cybersecurity incident. Depending on the nature and severity of the incident, the plan requires escalating notifications up to our CEO, the Audit Committee and our Board.

*Cybersecurity Risk Management*

Our cybersecurity risk management program is integrated into our overall enterprise risk management program, and shares common methodologies, reporting channels and governance processes that apply across the enterprise risk management program consistent with other legal, compliance, strategic, operational, and financial risk areas. Our program is guided by cybersecurity frameworks, such as the National Institute of Standards and Technology Cybersecurity Framework (NIST CSF), although we also look to other standards to help us identify, assess, and manage cybersecurity risks relevant to our business.

The Company has a robust cybersecurity program to assess, identify and manage material risk from cybersecurity threats and to prevent, detect and respond to cybersecurity threats, including those associated with the use of third-party service providers. Our approach to cybersecurity risk management includes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Cybersecurity awareness training, including interactive simulations and tabletop exercises for our employees, incident response personnel, and senior management

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Periodic risk assessments designed to help identify significant or potentially material cybersecurity risks to our critical systems, information, and our broader enterprise information technology (IT) environment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The use of external service providers, where appropriate, to assess, test or otherwise assist with aspects of our security controls;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A multi-layered defense and continuous monitoring strategy employing various tools and testing, and incorporating lessons learned from our defense and monitoring efforts to help prevent future attacks; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Information security assessments conducted on third parties with whom we share sensitive electronic data against established cybersecurity frameworks;

While the Company's information systems are exposed to cybersecurity threats and risks, we have not experienced any material cybersecurity incidents during 2025, 2024 or 2023, and any costs or operational impacts related to cybersecurity incidents were immaterial during this period. We continue to invest in cybersecurity and the resiliency of our networks, including our controls and processes, all of which are designed in an effort to protect our IT systems and infrastructure, and the information they contain. For more information regarding the risks we face from cybersecurity threats, please see Item 1A - Risk Factors.

**<u>ITEM 7 – MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS</u>**

**OVERVIEW** 

Our company is comprised of two reporting segments: North America and Rest of World. Our Rest of World segment is primarily comprised of China, India, and Europe. Both segments manufacture and market comprehensive lines of residential and commercial gas, heat pump and electric water heaters, boilers, tanks, and water treatment products. Both segments primarily manufacture and market in their respective region of the world.

Consistent with our stated strategic priorities, we continue to seek acquisitions that enable growth, expand our core business, and establish adjacencies. In November 2025, we announced that we signed a definitive agreement to acquire LVC Holdco LLC (Leonard Valve) for $470 million, subject to customary adjustments, and was funded with cash borrowed under a new term loan with a group of eight banks. The transaction was completed in January 2026. Leonard Valve is a leading manufacturer of water temperature and flow solutions and we believe it represents a compelling strategic fit and a meaningful advancement into our presence in the water management market. Leonard Valve is projected to contribute approximately $70 million in sales in 2026 in the North America segment. On November 1, 2024, we acquired Pureit from Unilever for approximately $125 million, subject to customary adjustments. Pureit, a leading water purification business in South Asia, offers a broad range of residential water purification solutions. Pureit contributed $54 million to sales in 2025 in the Rest of World segment. The acquisition fits squarely in our core capabilities and doubled our market penetration in the South Asia region.

We continue to look for opportunities to add to our existing product portfolio in high growth regions demonstrated by our previous introductions of kitchen products and connected product technologies in China. We also recently introduced our internally designed and manufactured gas tankless water heaters in North America. In addition, we are expanding our commercial water heater capacity in North America in preparation for the new efficiency rule for commercial water heaters that the Department of Energy (DOE) has adopted that will take effect in October 2026.

In our North America segment, water heater sales increased one percent in 2025 compared to 2024 as pricing benefits and higher commercial volumes were partially offset by lower wholesale residential volumes. We estimate that 2025 residential industry unit volumes were approximately flat compared to the prior year and we project 2026 industry residential unit volumes will be flat to down, driven by softness in new construction. We anticipate that commercial water heater industry volumes will increase mid-single digits in 2026 after growing approximately five percent in 2025. We believe that the 2026 growth will come from the buy ahead of products that will be eliminated as a part of the DOE regulatory change for commercial water heaters that will take effect in October 2026. In response to higher steel and other input costs, including tariffs, we announced price increases on most of our water heater and boiler products in the first half of 2025. In addition to pricing, we continue to mitigate the impact of tariffs through footprint optimization, strategic sourcing actions and other cost containment initiatives. Our boiler sales grew eight percent in 2025 primarily due to higher volumes and pricing benefits. We expect our boiler sales to grow between six and eight percent in 2026 due to carryover pricing benefits and continued demand for our commercial high efficiency condensing gas boilers. We anticipate sales of our North America water treatment products will grow between 10 and 12 percent primarily due to tariff-related pricing benefits and as we continue to expand our dealer network.

In our Rest of World segment, China third-party sales declined 12 percent in local currency in 2025 due to continued weak consumer demand and the cessation of the government appliance subsidy programs in the second half of the year. For the full year 2026, we project our third-party sales in China to decrease mid-single digits in local currency compared to 2025 due to continued softness in consumer demand. In the third quarter of 2025, we initiated an assessment of strategic opportunities for our China business, including strategic partnerships and other alternatives. We believe the China market has substantial long-term prospects and are committed to realizing the potential upside inherent in our China business. The assessment is ongoing.

Combining all of these factors, we expect our 2026 consolidated sales to grow between two and five percent compared to 2025. Our guidance excludes the impacts from potential future acquisitions, any potential outcomes of the assessment of the China business and changes to tariffs.

---

Our sales in 2025 were $3,830.2 million, an increase of $12.1 million compared to 2024 sales of $3,818.1 million. Our net sales increase was mainly due to implementing price increases to address rising input costs, including tariffs, as well as higher sales volumes of commercial water heaters and boilers. Additionally, the acquisition of Pureit in late 2024 contributed incremental sales of $54 million in 2025. These positive factors outweighed the impact of decreased volumes in China, lower residential water heater sales in North America, and an unfavorable currency translation of approximately $7 million due to the depreciation of foreign currencies compared to the U.S. dollar.

Our 2025 gross profit margin of 38.8 percent increased compared to 38.1 percent in 2024. The higher gross profit margin in 2025 compared to 2024 was primarily driven by the benefits of pricing actions implemented early in 2025 to address increased input costs in North America and higher mix of commercial water heaters and boilers.

Selling, general, and administrative (SG&A) expenses were $759.4 million in 2025, or $20.1 million higher than in 2024. The increase in SG&A expenses in 2025 compared to the prior year was primarily due to higher employee costs, partially offset by benefits of our 2024 China restructuring actions.

We recognized $17.6 million of restructuring and impairment expenses during the year ended December 31, 2024. Of these expenses, $6.3 million was related to our water treatment business in the North America segment and was a result of a profitability improvement strategy that prioritizes improving our cost structure and emphasizes more profitable channels. In the Rest of World segment, restructuring included severance costs in China of $11.3 million and was related to the right sizing of that business for current market conditions. Restructuring and impairment expenses in 2023 were $18.8 million, of which $15.7 million was recorded in the Rest of World segment and $3.1 million was recorded in Corporate Expense and related primarily to the sale of our business in Turkey.

Interest expense was $13.5 million in 2025, compared to $6.7 million in 2024. The increase in interest expense in 2025 compared to the prior year was primarily due to higher average debt levels throughout 2025.

Other income - net for 2025 was income of $0.6 million, compared to income of $8.5 million in 2024. The decrease in other income - net was driven by lower foreign currency translation losses compared to the prior year and lower interest income from lower average cash balances.

Our effective income tax rate in 2025 and 2024 was 23.6 percent and 23.9 percent, respectively. The change in the effective income tax rate in 2025 compared to the prior year was primarily due to reductions in US cross-border tax. We estimate that our annual effective income tax rate for the full year of 2026 will be approximately 24 to 24.5 percent.

We are providing non-U.S. Generally Accepted Accounting Principles (GAAP) measures (adjusted earnings, adjusted earnings per share (EPS), total segment earnings, and adjusted segment earnings) that exclude the impact of restructuring and impairment expenses. Reconciliations from GAAP measures to non-GAAP measures are provided in the *Non-GAAP Measures* section below. We believe that the measures of adjusted earnings, adjusted EPS, total segment earnings, adjusted segment earnings, and free cash flow provide useful information to investors about our performance and allow management and our investors to better understand our performance between periods without regard to items that we do not consider to be a component of our core operating performance or recurring in nature.

| Segment Earnings | 727.9 | 707.5 |
| &nbsp;&nbsp;*Segment Margin* | *24.4 %* | *24.0 %* |

---

Sales in our North America segment were $2,984.2 million in 2025, or $34.1 million higher than sales of $2,950.1 million in 2024. Our net sales increase in 2025 was driven by pricing actions and higher commercial water heater and boiler volumes, which were partially offset by lower residential water heater volumes and unfavorable currency translation of approximately $6 million.

North America segment earnings were $727.9 million in 2025, or $20.4 million higher than segment earnings of $707.5 million in 2024. Segment margins were 24.4 percent and 24.0 percent in 2025 and 2024, respectively. Higher segment earnings and segment margin in 2025 compared to 2024 were primarily driven by pricing benefits, higher boiler and commercial water heater volumes that more than offset lower residential water heater volumes and higher input costs, including tariffs. Segment earnings and margin in 2024 included restructuring and impairment expenses of $6.3 million related to our water treatment business and a result of a profitability improvement strategy that prioritizes improving our cost structure and emphasizes our more profitable channels.

Adjusted segment earnings and adjusted segment margin in 2024 were $713.8 million and 24.2 percent, respectively, which excludes $6.3 million of pre-tax restructuring and impairment expenses. We estimate our 2026 North America segment margin will be approximately 24.0 to 24.5 percent.

***Rest of World Segment***

---

| | | |
|:---|:---|:---|
| <u>Years ended December 31 (dollars in millions)</u> | 2025 | 2024 |
| Net Sales | $880.4 | $918.6 |
| Segment Earnings | 76.4 | 64.5 |
| &nbsp;&nbsp;*Segment Margin* | *8.7 %* | *7.0 %* |

---

Sales in our Rest of World segment were $880.4 million in 2025, or $38.2 million lower than sales of $918.6 million in 2024. Our net sales decrease in 2024 was due to lower volumes of our residential water treatment and water heater products in China that were partially offset by incremental sales of approximately $53 million related to our 2024 acquisition of Pureit.

Rest of World segment earnings were $76.4 million in 2025 and higher compared to $64.5 million in 2024. Segment margins were 8.7 percent and 7.0 percent in 2025 and 2024, respectively. The higher segment earnings and segment margin in 2025 compared to 2024 were primarily driven by the benefits of restructuring actions taken at the end of 2024 and other cost saving measures that more than offset lower sales in China. Segment earnings and margin in 2024 included restructuring and impairment expenses of $11.3 million. Restructuring and impairment expenses in 2024 were severance costs in China related to the right sizing of that business for current market conditions.

Adjusted segment earnings and adjusted segment margin in 2024 were $75.8 million and 8.3 percent, respectively. Adjusted segment earnings and adjusted segment margin in 2024 exclude $11.3 million of restructuring and impairment expenses. We estimate our 2026 Rest of World segment margin will be approximately eight to nine percent.

***Outlook***

As we begin 2026, we expect our consolidated sales to be up approximately two to five percent compared to 2025. Our projection is driven by the additional sales expected from our Leonard Valve acquisition, as well as boiler sales growth of six to eight percent compared to 2025 due to the carryover of pricing benefits and the continuation of the transition to energy-efficient boilers. In our Rest of the World segment, after a challenging 2025, we expect consumer demand softness will persist in 2025 in China and a decline in third-party sales of mid-single digits compared to 2025. Our 2025 full year earnings was $3.85 per share and we expect 2026 full-year earnings of between $3.85 and $4.15 per share. Our guidance excludes the impacts of potential future acquisitions, any potential outcomes of the assessment of the China business, and changes to tariffs.

**LIQUIDITY AND CAPITAL RESOURCES** 

Our working capital was $429.0 million at December 31, 2025, compared with $495.7 million at December 31, 2024. The decrease in working capital was primarily related to lower inventory, cash balances, and increased short term debt maturities. As of December 31, 2025, cash balances were positively impacted by changes in foreign currency during the year of $4.2 million. Cash and cash equivalents used to fund our operations are primarily generated through operating activities and our existing credit facilities. We believe our available cash and existing credit facilities are sufficient to cover our cash needs for the foreseeable future. We use a global cash pooling arrangement, intercompany borrowing, and some local credit lines to meet funding needs and allocate capital resources among various entities. We have historically made and anticipate future cash repatriations from certain foreign subsidiaries. In 2025, we repatriated approximately $109 million of cash from our foreign subsidiaries and used the proceeds to pay down outstanding debt balances.

| Cash used in investing activities | (53.0) | (267.1) |
| Cash used in financing activities | (633.1) | (408.4) |

---

Cash provided by operations in 2025 was $616.8 million and higher than $581.8 million in 2024, primarily as a result of higher earnings and a one-time tax adjustment related to a tax law change that benefited 2025. Our free cash flow in 2025 and 2024 was $546.0 million and $473.8 million, respectively. We expect cash provided by operating activities to be between $605 million and $655 million in 2026. We expect free cash flow to be between $525 million and $575 million in 2026. Free cash flow is a non-GAAP measure described in more detail in the *Non-GAAP Measures* section below.

Capital expenditures totaled $70.8 million in 2025 compared with $108.0 million in 2024. Lower capital expenditures compared to the prior year were primarily due to our capacity expansion projects in Juarez, Mexico and McBee, South Carolina and our new engineering facility in Lebanon, Tennessee in 2024. We project that 2026 capital expenditures will be between $70 million and $80 million and full-year depreciation and amortization expense will be approximately $100 million.

In 2024, we renewed and amended our $500 million revolving credit facility ("renewed facility") which now expires on August 23, 2029. The renewed facility is with a group of nine banks and has an accordion provision that allows it to be increased up to $1 billion if certain conditions (including lender approval) are satisfied. Borrowing rates under the renewed facility are determined by our leverage ratio. The renewed facility requires us to maintain two financial covenants, a leverage ratio test and an interest coverage test, and we were in compliance with the covenants as of December 31, 2025, and expect to be in compliance for the foreseeable future. The renewed facility backs up commercial paper and credit line borrowings. At December 31, 2025, we had no borrowings outstanding under the renewed facility and an available borrowing capacity of $500.0 million. We believe the combination of available borrowing capacity and operating cash flows will provide sufficient funds to finance our existing operations for the foreseeable future.

Our total debt decreased by $38.2 million in 2025 as we used available cash to pay down outstanding debt balances. Our leverage, as measured by the ratio of total debt to total capitalization, was 7.7 percent at December 31, 2025, compared with 9.3 percent at December 31, 2024.

On January 6, 2026, we completed the acquisition of Leonard Valve for $470 million. The acquisition was funded under a new three-year, $470 million term loan with a group of eight banks. The Company borrowed the full available amount on January 5, 2026 and used the proceeds to finance the purchase.

In 2025, our Board of Directors approved adding 5,000,000 shares of common stock to our existing discretionary share repurchase authority. Under our share repurchase program, we may purchase our common stock through a combination of a Rule 10b5-1 automatic trading plan and discretionary purchases in accordance with applicable securities laws. The stock

**<u>[**Table of Contents**](#i1de722994910418ea076e2893b84ba6c_7)</u>**

repurchase authorization remains effective until terminated by our Board of Directors, which may occur at any time, subject to the parameters of any Rule 10b5-1 automatic trading plan that we may then have in effect. During 2025, we repurchased 5,942,601 shares of our stock at a total cost of $400.8 million. As of December 31, 2025, we had 803,524 shares remaining on the share repurchase authority. On January 28, 2026, the Board of Directors approved adding 5,000,000 shares of common stock to the existing discretionary share repurchase authority. Including the additional shares, we had 5,545,241 shares available for repurchase as of the date of the Board of Directors' approval. We intend to repurchase approximately $200 million of our common stock in 2026 through a combination of 10b5-1 plans and open-market purchases.

We paid dividends of $1.38 per share in 2025 compared with $1.30 per share in 2024. We increased our dividend by six percent in the fourth quarter of 2025, and the five-year compound annual growth rate of our dividend payment is approximately seven percent. We have paid dividends for 86 consecutive years with annual amounts increasing each of the last 34 years.

**Recent Accounting Pronouncements** 

Refer to *Recent Accounting Pronouncements* in Note 1, "Organization and Significant Accounting Policies" of Notes to the Consolidated Financial Statements.

**Critical Accounting Policies** 

Our accounting policies are described in Note 1, "Organization and Significant Accounting Policies" of Notes to the Consolidated Financial Statements. Also as disclosed in Note 1, the preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires the use of estimates and assumptions about future events that affect the amounts reported in the financial statements and accompanying notes. Future events and their effects cannot be determined with absolute certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results inevitably will differ from those estimates, and such differences may be material to the financial statements.

The most significant accounting estimates inherent in the preparation of our financial statements include estimates associated with the evaluation of the impairment of goodwill and indefinite-lived intangible assets and significant estimates used in the determination of the liability related to product warranties. Various assumptions and other factors underlie the determination of these significant estimates. The process of determining significant estimates is fact-specific and takes into account factors such as historical experience and trends, and in some cases, actuarial techniques. We monitor these significant factors and adjustments are made as facts and circumstances dictate. Historically, actual results have not significantly deviated from those determined using the estimates described above.

*Goodwill and Indefinite-lived Intangible Assets* 

In conformity with GAAP, goodwill and indefinite-lived intangible assets are tested for impairment annually or more frequently if events or changes in circumstances indicate that the assets might be impaired. We perform impairment reviews for our reporting units using a fair-value method based on management's judgments and assumptions. The fair value represents the estimated amount at which a reporting unit could be bought or sold in a current transaction between willing parties on an arms-length basis. The estimated fair value is then compared with the carrying amount of the reporting unit, including recorded goodwill. We are subject to financial statement risk to the extent that goodwill and indefinite-lived intangible assets become impaired. Any impairment review is, by its nature, highly judgmental as estimates of future sales, earnings and cash flows are utilized to determine fair values. However, we believe that we conduct a thorough and competent annual quantitative analysis of goodwill and indefinite-lived intangible assets. Based on the annual goodwill impairment test, we determined there was no impairment of our goodwill as of December 31, 2025. The fair value of each of our reporting units significantly exceeded its carrying value. Based on the annual indefinite-lived assets impairment test, we determined there was no impairment of our indefinite-lived assets as of December 31, 2025.

*Product Warranty* 

Our products carry warranties that generally range from one to 12 years and are based on terms that are generally accepted in the market. We provide for the estimated cost of product warranty at the time of sale. The product warranty provision is estimated based on warranty loss experience using actual historical failure rates and estimated costs of product replacement. The variables used in the calculation of the provision are reviewed at least annually. At times, warranty issues may arise which are beyond the scope of our historical experience. We provide for any such warranty issues as they become known and estimable. While our warranty costs have historically been within calculated estimates, it is possible that future warranty costs could differ significantly from those estimates. The allocation of the warranty liability between current and long-term is based on the expected warranty liability to be paid in the next year as determined by historical product failure rates. At December 31, 2025 and 2024, our reserve for product warranties was $209.7 million and $190.4 million, respectively.

*Non-GAAP Measures* 

We are providing non-U.S. Generally Accepted Accounting Principles (GAAP) measures (adjusted earnings, adjusted EPS, total segment earnings, and adjusted segment earnings) that exclude the impact of restructuring and impairment expenses. Reconciliations from GAAP measures to non-GAAP measures are provided below.

We believe that the measures of adjusted earnings, adjusted EPS, adjusted segment earnings and free cash flow provide useful information to investors about our performance and allow management and our investors to better understand our performance between periods without regard to items that we do not consider to be a component of our core operating performance or recurring in nature.

**OTHER MATTERS** 

**Environmental** 

Our operations are governed by a number of federal, foreign, state, local and environmental laws concerning the generation and management of hazardous materials, the discharge of pollutants into the environment and remediation of sites owned by the Company or third parties. We have expended financial and managerial resources complying with such laws. Expenditures related to environmental matters were not material in 2025 and we do not expect them to be material in any single year. We have reserves associated with environmental obligations at various facilities and we believe these reserves together with available insurance coverage are sufficient to cover reasonably anticipated remediation costs. Although we believe that our operations are substantially in compliance with such laws and maintain procedures designed to maintain compliance, there are no assurances that substantial additional costs for compliance will not be incurred in the future. However, since the same laws govern our competitors, we should not be placed at a competitive disadvantage.

**Risk Management**

We evaluate risk to our business in a number of ways, primarily through our Enterprise Risk Management (ERM) process, which we conduct enterprise-wide on a periodic basis, and seeks to identify and address significant and material risks. Our ERM process assesses, manages, and monitors risks consistent with the integrated risk framework in the *Enterprise Risk Management-Integrated Framework* (2017) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). We believe that risk-taking is an inherent aspect of the pursuit of our strategy. Our goal is to manage risks prudently rather than avoid risks. We can mitigate risks and their impact on our company only to a limited extent.

A team of senior executives prioritizes identified risks, including decarbonization, new technologies and cyber threats among others, and assigns an executive to address each major identified risk area and lead action plans to manage risks. Our Board of Directors provides oversight of the ERM process and reviews significant identified risks. The Audit Committee of the Board of Directors also reviews significant financial risk exposures and the steps management has taken to monitor and manage them. Our other Board committees also play a role in risk management, as set forth in their respective charters.

Our goal is to proactively manage risks using a structured approach in conjunction with strategic planning, with the intent to preserve and enhance shareholder value. However, the risks set forth in Item 1A - Risk Factors and elsewhere in this Annual Report on Form 10-K and other risks and uncertainties could adversely affect us and cause our results to vary materially from recent results or from our anticipated future results.

**Market Risk** 

We are exposed to various types of market risks, primarily currency. We monitor our risks in such areas on a continuous basis and generally enter into forward contracts to minimize such exposures. We do not engage in speculation in our derivatives strategies. Further discussion regarding derivative instruments is contained in Note 1, "Organization and Significant Accounting Policies" of Notes to Consolidated Financial Statements.

We enter into foreign currency forward contracts to minimize the effect of fluctuating foreign currencies. At December 31, 2025, we had net foreign currency contracts outstanding with notional values of $93.3 million. Assuming a hypothetical ten percent movement in the respective currencies, the potential foreign exchange gain or loss associated with the change in exchange rates would amount to $9.3 million. However, gains and losses from our forward contracts will be offset by gains and losses in the underlying transactions being hedged.

**<u>ITEM 8 – FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA</u>**

**Report of Independent Registered Public Accounting Firm**

To the Stockholders and the Board of Directors of A. O. Smith Corporation

**Opinion on the Financial Statements** 

We have audited the accompanying consolidated balance sheets of A. O. Smith Corporation (the Company) as of December 31, 2025 and 2024, the related consolidated statements of earnings, comprehensive earnings, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 10, 2026 expressed an unqualified opinion thereon.

**Basis for Opinion** 

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical Audit Matter**

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments.

| | |
|:---|:---|
| | ***Product Warranty Liability*** |
| *Description of the Matter* | At December 31, 2025, the Company's product warranty liability was $209.7 million. As discussed in Note 1 of the consolidated financial statements, the Company records a liability for the expected cost of warranty-related claims at the time of sale. The product warranty liability is estimated based upon warranty loss experience using actual historical failure rates and estimated cost of product replacement. Products generally carry warranties from one to twelve years. The Company performs separate warranty calculations based on the product type and the warranty term and aggregates them. |
|  | Auditing the Company's product warranty liability for certain of its products was complex due to the judgmental nature of the warranty loss experience assumptions, including the estimated product failure rate and the estimated cost of product replacement. In particular, it is possible that future product failure rates may not be reflective of actual historical product failure rates, or that a product quality issue has not yet been identified. Additionally, the cost of product replacement could differ from estimates due to fluctuations in the replacement cost of the product. |
| *How We Addressed the Matter in our Audit* | We obtained an understanding, evaluated the design, and tested the operating effectiveness of controls over the Company's product warranty liability calculation. For example, we tested controls over management's review of the product warranty liability calculation, including the significant assumptions and the data inputs to the calculation. <br>To test certain products of the Company's product warranty liability calculation, our audit procedures included, among others, evaluating the methodology used, and testing the significant assumptions discussed above and the underlying data used by the Company in its analysis. We tested the completeness and accuracy of the claims settled data. We recalculated the historical failure rates using actual claims settled data. We compared the estimated cost of replacement included in the product warranty liability with the current costs to manufacture a comparable product and assessed the impact of projected changes in significant product costs. We also analyzed current year claims settled data to identify changes in failure trends and assessed the historical accuracy of the prior year liability. |

**<u>[**Table of Contents**](#i1de722994910418ea076e2893b84ba6c_7)</u>**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**1. Organization and Significant Accounting Policies**

**Organization.** A. O. Smith Corporation (A. O. Smith or the Company) is comprised of two reporting segments: North America and Rest of World. The Rest of World segment is primarily comprised of China, India, and Europe. Both segments manufacture and market comprehensive lines of residential and commercial gas and electric water heaters, boilers, tanks and water treatment products. Both segments primarily manufacture and market in their respective regions of the world.

**Consolidation.** The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries after elimination of intercompany transactions.

**Use of estimates.** The preparation of financial statements in conformity with accounting principles generally accepted in the United States (U.S.) requires management to make estimates and assumptions that affect the amounts reported in the accompanying financial statements and notes. Actual results could differ from those estimates.

**Fair value of financial instruments.** The carrying amounts of cash, cash equivalents, marketable securities, receivables, floating rate debt and trade payables approximated fair value as of December 31, 2025 and 2024, due to the short maturities or frequent rate resets of these instruments. The fair value of term notes with financial institutions included in Long-term debt within the consolidated balance sheets was approximately $139.0 million as of December 31, 2025 compared with the carrying amount of $155.0 million for the same date. The fair value of term notes with financial institutions was approximately $143.6 million as of December 31, 2024 compared with the carrying amount of $163.2 million.

**Foreign currency translation.** For all subsidiaries outside the U.S., with the exception of its Barbados, Hong Kong and Mexican companies and its non-operating companies in the Netherlands, the Company uses the local currency as the functional currency. For those operations using a functional currency other than the U.S. dollar, assets and liabilities were translated into U.S. dollars at year-end exchange rates, and revenues and expenses were translated at weighted-average exchange rates. The resulting translation adjustments were recorded as a separate component of stockholders' equity. The Barbados, Hong Kong, Mexican and non-operating Netherlands companies use the U.S. dollar as the functional currency. Gains and losses from foreign currency transactions were included in net earnings and were not significant in 2025, 2024, or 2023.

**Cash and cash equivalents.** The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.

**Marketable securities.** The Company considers all highly liquid investments with maturities greater than 90 days when purchased to be marketable securities. At December 31, 2025, the Company's marketable securities consisted of bank time deposits with original maturities ranging from 180 days to 12 months and were primarily located at investment grade rated banks in China and Hong Kong.

**Inventory valuation.** Inventories are carried at lower of cost or net realizable value. Cost is determined on the last-in, first-out (LIFO) method for a certain portion of the Company's domestic inventories, which comprised 40 percent and 43 percent of the Company's total inventory at December 31, 2025 and 2024, respectively. The inventories of foreign subsidiaries and the remaining domestic inventories and supplies were determined using the first-in, first-out (FIFO) method.

**Property, plant and equipment.** Property, plant and equipment are stated at cost. Depreciation is computed primarily by the straight-line method. The estimated service lives used to compute depreciation are generally 25 to 50 years for buildings, three to 20 years for equipment and three to 15 years for software. Maintenance and repair costs are expensed as incurred.

**Goodwill and other intangibles.** Goodwill and indefinite-lived intangible assets are not amortized but are reviewed for impairment on an annual basis. Separable intangible assets, primarily comprised of customer relationships, that are not deemed to have an indefinite life are amortized on a straight-line basis over their estimated useful lives which range from two to 25 years.

**Impairment of long-lived and amortizable intangible assets.** Property, plant and equipment and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected undiscounted cash flows is less than the carrying value of the related asset or group of assets, a loss is recognized for the difference between the fair value and carrying value of the asset or group of assets. Such analyses involves significant judgment.

**Product warranties.** The Company's products carry warranties that generally range from one to twelve years and are based on terms that are consistent with the market. The Company records a liability for the expected cost of warranty-related claims

**1. Organization and Significant Accounting Policies (continued)**

at the time of sale and is estimated based on the warranty period, product type and loss experience using actual historical failure rates and estimated costs of product replacement. The variables used in the calculation of the provision are reviewed by the Company at least annually. At times, warranty issues may arise which are beyond the scope of the Company's historical experience. The Company provides for any such warranty issues as they become known and estimable. The allocation of the warranty liability between current and long-term is based on expected warranty claims to be settled in the next year as determined by historical product failure rates.

The following table presents the Company's product warranty liability activity in 2025 and 2024:

---

| | | |
|:---|:---|:---|
| <u>Years ended December 31 (dollars in millions)</u> | 2025 | 2024 |
| Balance at beginning of year | $190.4 | $188.1 |
| Expense | 84.2 | 81.1 |
| Claims settled | (66.0) | (78.8) |
| Acquired obligations | 1.1 |  |
| Balance at end of year | $209.7 | $190.4 |

---

**Derivative instruments.** The Company utilizes certain derivative instruments to enhance its ability to manage currency as well as raw materials price risk. The Company does not enter into contracts for speculative purposes. The fair values of all derivatives are recorded in the consolidated balance sheets. The change in a derivative's fair value is recorded each period in current earnings or accumulated other comprehensive loss (AOCL), depending on whether the derivative is designated as part of a hedge transaction and if so, the type of hedge transaction. See Note 13, "Derivative Instruments" for disclosure of the Company's derivative instruments and hedging activities.

**Fair Value Measurements.** Accounting Standards Codification (ASC) 820 *Fair Value Measurements*, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring basis or nonrecurring basis. ASC 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

Assets and liabilities measured at fair value are based on the market approach which are prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.

Assets (liabilities) measured at fair value on a recurring basis are as follows (dollars in millions):

---

| | | | |
|:---|:---|:---|:---|
| <u>Fair Value Measurement Using</u> | <u>Balance Sheet Location</u> | December 31, 2025 | December 31, 2024 |
| Quoted prices in active markets for identical assets (Level 1) | Marketable Securities | $18.7 | $36.5 |
| Significant other observable inputs (Level 2) | Accrued liabilities |  | (1.9) |

---

There were no changes in the valuation techniques used to measure fair values on a recurring basis.

**Revenue recognition.** Substantially all of the Company's sales are from contracts with customers for the purchase of its products. Contracts and customer purchase orders are used to determine the existence of a sales contract. Shipping documents are used to verify shipment. For substantially all of its products, the Company transfers control of products to the customer at the point in time when title and risk are passed to the customer, which generally occurs upon shipment of the product. See Note 2, "Revenue Recognition" for disclosure of the Company's revenue recognition activities.

**Advertising.** The majority of advertising costs are charged to operations as incurred and totaled $101.1 million, $100.3 million and $93.9 million during 2025, 2024 and 2023, respectively. Included in total advertising costs are expenses associated with store displays for water heater, water treatment products, and kitchen products in China that are amortized over 12 to 48 months which totaled $24.0 million, $21.1 million and $15.2 million during 2025, 2024 and 2023, respectively.

**<u>[**Table of Contents**](#i1de722994910418ea076e2893b84ba6c_7)</u>**

**1. Organization and Significant Accounting Policies (continued)**

**Research and development.** Research and development costs are charged to operations as incurred and amounted to $95.0 million, $101.7 million and $97.5 million during 2025, 2024 and 2023, respectively.

**Environmental costs.** The Company accrues for costs associated with environmental obligations when such costs are probable and reasonably estimable. Costs of estimated future expenditures are not discounted to their present value. Recoveries of environmental costs from other parties are recorded as assets when their receipt is considered probable. The accruals are adjusted as facts and circumstances change.

**Stock-based compensation.** Compensation cost is recognized using the straight-line method over the vesting period of the award and forfeitures are recognized as they occur. In accordance with amended ASC 718 *Compensation-Stock Compensation*, the Company recognized $0.6 million, $4.1 million, and $3.2 million of discrete income tax benefits on settled stock based compensation awards during 2025, 2024, and 2023 respectively.

**Income taxes.** The provision for income taxes is computed using the asset and liability method, in accordance with ASC 740 *Income Taxes*, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities and for operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled and are classified as noncurrent in the consolidated balance sheet. The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized.

The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon settlement.

**Earnings per share of common stock.** The Company is not required to use the two-class method of calculating earnings per share because its Class A Common Stock and Common Stock have equal dividend rights. The numerator for the calculation of basic and diluted earnings per share is net earnings. The following table sets forth the computation of basic and diluted weighted-average shares used in the earnings per share calculations:

---

| | | | |
|:---|:---|:---|:---|
| | 2025 | 2024 | 2023 |
| Denominator for basic earnings per share - weighted-average shares outstanding | 141029845 | 145997584 | 149952679 |
| Effect of dilutive stock options, restricted stock and share units | 884995 | 1086496 | 1062895 |
| Denominator for diluted earnings per share | 141914840 | 147084080 | 151015574 |

*Recent Accounting Pronouncements*

In September 2025, the FASB issued ASU No. 2025-06, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40), which modernizes the accounting guidance for internal-use software costs by eliminating the requirement to assess software development stages and introduces a new capitalization threshold. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently in the process of reviewing the guidance and evaluating its impact on its financial statements.

In November 2024, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2024-03 "Income Statement - Reporting Comprehensive Income (Topic 220): Disaggregation of Income Statement Expenses." The ASU requires additional disclosures by disaggregating the costs and expense line items that are presented on the face of the income statement. The ASU is effective for the Company beginning with its 2027 annual disclosures and subsequent interim periods. Early adoption is permitted. This ASU requires a public company to apply the amendments either prospectively to financial statements issued for reporting periods after the effective date of this ASU or retrospectively to any or all prior periods presented in the financial statements. The Company is currently evaluating the impact of adopting this ASU on its disclosures.

In December 2023, the FASB amended ASC 740 (issued under ASU 2023-09, "Improvements to Income Tax Disclosures"). This ASU requires added disclosures related to the tax rate reconciliation and income taxes paid and includes other amendments intended to improve effectiveness and comparability. The update is effective for the Company beginning with its 2025 annual disclosures and interim periods beginning in 2026. As a result of adoption, income tax disclosures for prior periods presented have been revised to conform to the new disclosure requirements. The adoption of ASU 2023-09 did not affect the Company's financial position or its results of operations. Refer to Note 14, Income Taxes, for additional disclosures.

**2. Revenue Recognition** 

Substantially all of the Company's sales are from contracts with customers for the purchase of its products. Contracts and customer purchase orders are used to determine the existence of a sales contract. Shipping documents are used to verify shipment. For substantially all of its products, the Company transfers control of products to the customer at the point in time when title and risk are passed to the customer, which generally occurs upon shipment of the product. Each unit sold is considered an independent, unbundled performance obligation. The Company's sales arrangements do not include other performance obligations that are material in the context of the contract.

The nature, timing and amount of revenue for a respective performance obligation are consistent for each customer. The Company measures the sales transaction price based upon the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. Sales and value added taxes are excluded from the measurement of the transaction price. The Company's payment terms for the majority of its customers are 30 to 90 days from shipment.

Additionally, certain customers in China pay the Company prior to the shipment of products resulting in a customer deposits liability of $34.2 million and $54.4 million at December 31, 2025 and December 31, 2024, respectively. Customer deposit liabilities are short term in nature, recognized into revenue within one year of receipt.

The Company assesses the collectability of customer receivables based on the creditworthiness of a customer as determined by credit checks and analysis, as well as the customer's payment history. In determining the allowance for credit losses, the Company also considers various factors including the aging of customer accounts and historical write-offs. In addition, the Company monitors other risk factors including forward-looking information when establishing adequate allowances for credit losses, which reflects the current estimate of credit losses expected to be incurred over the life of the receivables. The Company's allowance for credit losses was $14.1 million and $12.9 million at December 31, 2025 and December 31, 2024, respectively.

Rebates and incentives are based on pricing agreements and are tied to sales volume. The amount of revenue is reduced for variable consideration related to customer rebates which are calculated using expected values and are based on program specific factors such as expected rebate percentages based on expected volumes. In situations where the customer has the right to return eligible products, the Company reduces revenue for its estimates of expected product returns, which are primarily based on an analysis of historical experience. Changes in such accruals may be required if actual sales volume differs from estimated sales volume or if future returns differ from historical experience. Shipping and handling costs billed to customers are included in net sales and the related costs are included in cost of products sold and are activities performed to fulfill the promise to transfer products.

*Disaggregation of Net Sales*

The Company is comprised of two reporting segments: North America and Rest of World. The Rest of World segment is primarily comprised of China, India, and Europe. Both segments manufacture and market comprehensive lines of residential and commercial gas, heat pump and electric water heaters, boilers, tanks and water treatment products. Both segments primarily manufacture and market in their respective regions of the world.

As each segment manufactures and markets products in its respective region of the world, the Company has determined that geography is the primary factor in reporting its sales. The Company further disaggregates its North America segment sales by major product line as each of North America's major product lines is sold through distinct distribution channels and these product lines may be impacted differently by certain economic factors. Within the Rest of World segment, particularly in China and India, the Company's major customers purchase across the Company's product lines, utilizing the same distribution channels regardless of product type. In addition, the impact of economic factors is unlikely to be differentiated by product line in the Rest of World segment.

The North America segment's major product lines are defined as the following:

*Water heaters* The Company's water heaters are open water heating systems that heat potable water. Typical applications for water heaters include residences, restaurants, hotels, office buildings, laundries, car washes and small businesses. The Company sells residential and commercial water heater products and related parts through its wholesale distribution channel, which includes approximately 800 independent wholesale plumbing distributors. The Company also sells residential water heaters and related parts through retail and maintenance, repair and operations (MRO) channels. A significant portion of the Company's water heater sales in the North America segment is derived from the replacement of existing products.

*Boilers* The Company's boilers are closed loop water heating systems used primarily for space heating or hydronic heating. The Company's boilers are primarily used in applications in commercial settings for hospitals, schools, hotels and other large

**2. Revenue Recognition (continued)**

commercial buildings while residential boilers are used in homes, apartments and condominiums. The Company's boiler distribution channel is comprised primarily of manufacturer representative firms, with the remainder of its boilers distributed through wholesale channels. The Company's boiler sales in the North America segment are derived from a combination of replacement of existing products and new construction.

*Water treatment products* The Company's water treatment products range from point-of-entry water softeners, solutions for problem well water, and whole-home water filtration products to on-the-go filtration bottles, point-of-use carbon, and reverse osmosis products. Typical applications for the Company's water treatment products include residences, restaurants, hotels and offices. The Company sells water treatment products through its retail and wholesale distribution channels, similar to water heaters. The Company's water treatment products are also sold through independent water quality dealers as well as directly to consumers including through e-commerce sales channels. A portion of the Company's sales of water treatment products in the North America segment is comprised of replacement filters.

The following table disaggregates the Company's net sales by segment. As described above, the Company's North America segment sales are further disaggregated by major product line. In addition, the Company's Rest of World segment sales are disaggregated by China and all other Rest of World.

**3. Acquisitions**

*<u>2024 Acquisitions</u>*

During the fourth quarter of 2024, the Company acquired Pureit, a residential water purification business in South Asia, from Unilever for an aggregate purchase price of $124.6 million. The acquired company is included in the Rest of World segment. The purchase price consists of an initial cash payment of $117.9 million upon the closing of the transaction and a separate payment of $6.7 million made under a transitional supply agreement with Unilever. The Company incurred acquisition costs of approximately $1.4 million.

The following table summarizes the final allocation of the fair value of the assets acquired and liabilities assumed at the date of acquisition. Of the $56.4 million of acquired identifiable intangible assets, $48.5 million was assigned to trademarks that are not subject to amortization, $3.7 million was assigned to patents which are amortized over 15 years, and the remaining $4.2 million million was assigned to customer relationships which are amortized over two to three years. The excess of the acquisition purchase price over the fair value assigned to the assets acquired and liabilities assumed was recorded as goodwill. The allocation of the purchase price to goodwill decreased by $0.8 million in 2025 due to valuation adjustments related to identifiable intangible assets.

**4. Leases**

The Company's lease portfolio consists of operating leases for buildings and equipment, such as forklifts and copiers, primarily in the United States and China. The Company defines a lease as a contract that gives the Company the right to control the use of a physical asset for a stated term. The Company pays the lessor for that right, with a series of payments defined in the contract and a corresponding right of use operating lease asset and liability are recorded. The Company has elected not to record leases with an initial term of 12 months or less on its consolidated balance sheet. To determine balance sheet amounts, required legal payments are discounted using the Company's incremental borrowing rate as of the inception of the lease. The incremental borrowing rate is the rate of interest that the Company would incur if it were to borrow, on a collateralized basis, an amount equal to the value of the leased item over a similar term, in a similar economic environment. Variable lease components not based on an index or rate are excluded from the measurement of the lease asset and liability and expensed as incurred for all asset classes.

Certain leases include one or more options to renew or terminate. Renewal terms can extend the lease term from one to five years and options to terminate can be effective within one year. The exercise of lease renewal or termination is at the Company's discretion and when it is determined to be reasonably certain to renew or terminate, the option is reflected in the measurement of lease asset and liability. The Company's lease agreements do not contain any arrangements related to material residual value guarantees, restrictive covenants or material subleases. Cash flows associated with leases are materially consistent with the expense recorded in the consolidated statement of earnings.

Supplemental balance sheet information related to leases is as follows:

As a result the Company recorded an impairment expense of $15.6 million, of which $12.5 million was recorded in the Rest of World segment, and $3.1 million was recorded in Corporate Expense. The impairment was recorded as a net reduction of $4.5 million to the assets and liabilities and $11.1 million for the anticipated liquidation of the cumulative foreign currency translation adjustment associated with the disposal group. The remaining carrying value of the disposal group was $0.6 million and classified as held for sale. During 2023, the Company sold the disposal group for an amount that approximated the carrying value of the net assets. Upon closing of the sale in the second quarter of 2023, the Company released $11.0 million of foreign currency translation losses from accumulated other comprehensive loss.

**12. Stock Based Compensation** 

The Company adopted the A. O. Smith Combined Incentive Compensation Plan (the Incentive Plan) effective January 1, 2007, and the Incentive Plan was most recently reapproved by stockholders on April 15, 2020. The Incentive Plan is a continuation of the A. O. Smith Combined Executive Incentive Compensation Plan which was originally approved by stockholders in 2002. The number of shares available for granting of options or share units at December 31, 2025, was 2,028,442 which includes 2,400,000 additional shares that were authorized on April 15, 2020 at the Company's annual meeting of stockholders. Upon stock option exercise or share unit vesting, shares are issued from treasury stock. Total stock based compensation expense recognized in 2025, 2024 and 2023 was $13.8 million, $14.9 million and $11.5 million, respectively.

**12. Stock Based Compensation (continued)**

*Share Units* 

Participants in the Incentive Plan may also be awarded share units. Share units vest three years after the date of grant. The Company granted 269,545, 195,497 and 168,807 share units under the Incentive Plan in 2025, 2024 and 2023, respectively.

The share units were valued at $17.9 million, $16.1 million and $11.3 million at the date of issuance in 2025, 2024 and 2023, respectively, based on the price of the Company's Common Stock at the date of grant. The share units are recognized as compensation expense ratably over the three-year vesting period; however, included in share unit expense was expense associated with accelerated vesting of share unit awards for certain employees who are retirement eligible or will become retirement eligible during the vesting period. Stock based compensation expense attributable to share units of $11.2 million, $12.5 million and $9.6 million was recognized in 2025, 2024 and 2023, respectively. Certain non-U.S.-based employees receive the cash value of the share price at the vesting date in lieu of shares. Unvested cash-settled awards are remeasured at each reporting period.

A summary of share unit activity under the Incentive Plan is as follows:

---

| | | |
|:---|:---|:---|
| | Number of Units | Weighted-Average <br>Grant Date Value |
| Issued and unvested at January 1, 2025 | 469269 | $71.50 |

| Issued and unvested at December 31, 2025 | 631307 | 68.92 |

---

*Performance Stock Units*

Beginning in 2023, certain executives may be awarded performance stock units under the Incentive Plan. Performance stock units vest over three years following the date of the grant. Performance stock units vest under a set of measurement criteria which are based upon achievement of certain Sustainability targets. Potential payouts range from zero to 150 percent of the target awards and changes from target amounts are reflected as performance adjustments. The Company granted 38,435, 29,475 and 24,580 performance stock units under the Incentive Plan in 2025, 2024 and 2023, respectively.

The performance stock units were valued at $2.5 million, $2.4 million and $1.7 million at the date of issuance in 2025, 2024 and 2023, respectively, based on the price of the Company's Common Stock at the date of grant. The performance stock units are recognized as compensation expense ratably over the three-year vesting period. Stock based compensation expense attributable to performance stock units of $2.5 million, $1.8 million and $0.7 million was recognized in 2025, 2024 and 2023, respectively. Certain non-U.S.-based executives receive the cash value of the share price at the vesting date in lieu of shares. Unvested cash-settled awards are remeasured at each reporting period.

A summary of stock unit activity under the Incentive Plan is as follows:

**13. Derivative Instruments**

The Company utilizes certain derivative instruments to enhance its ability to manage currency exposure as well as raw materials price risk. Derivative instruments are entered into for periods consistent with the related underlying exposures and do not constitute positions independent of those exposures. The Company does not enter into contracts for speculative purposes. The contracts are executed with major financial institutions with no credit loss anticipated for failure of the counterparties to perform.

*<u>Cash Flow Hedges</u>*

With the exception of its net investment hedges, the Company designates all of its hedging instruments as cash flow hedges. For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), gains or losses on the derivative instrument are reported as a component of other comprehensive loss, net of tax, and are reclassified into earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings.

*Foreign Currency Forward Contracts* 

The Company is exposed to foreign currency exchange risk as a result of transactions in currencies other than the functional currency of certain subsidiaries. The Company utilizes foreign currency forward purchase and sale contracts to manage the volatility associated with foreign currency purchases, sales and certain intercompany transactions in the normal course of business. Principal currencies for which the Company utilizes foreign currency forward contracts include the British pound, Canadian dollar, Euro and Mexican peso.

Gains and losses on these instruments are recorded in accumulated other comprehensive loss, net of tax, until the underlying transaction is recorded in earnings. When the hedged item is realized, gains or losses are reclassified from accumulated other comprehensive loss to the consolidated statement of earnings. The assessment of effectiveness for forward contracts is based on changes in the forward rates. These hedges have been determined to be effective.

The majority of the amounts in accumulated other comprehensive loss for cash flow hedges are expected to be reclassified into earnings within one year. The combined fair value of the foreign currency forward contracts was an asset balance of $1.0 million as of December 31, 2025 which was recorded in Other current assets within the consolidated balance sheet. The combined fair value of the foreign currency forward contracts was a liability balance of $1.4 million as of December 31, 2024 and recorded in Accrued liabilities within the consolidated balance sheet.

The following table summarizes, by currency, the contractual amounts of the Company's foreign currency forward contracts that are designated as cash flow hedges:

---

| | | | | |
|:---|:---|:---|:---|:---|
| <u>December 31 (dollars in millions)</u> | 2025 | 2025 | 2024 | 2024 |
|  | Buy | Sell | Buy | Sell |
| Canadian dollar | $— | $57.8 | $— | $28.9 |
| Euro | 16.8 |  | 14.0 |  |
| Mexican peso | 18.7 |  | 27.2 |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total | $35.5 | $57.8 | $41.2 | $28.9 |

---

*Interest Rate Swaps*

The Company is exposed to interest rate risk as a result of its floating rate borrowings. The Company entered into a forward interest rate swap agreement with an independent counterparty to hedge the variability in cash flows due to changes in Secured Overnight Financing Rate (SOFR) benchmark interest rate associated with variable rate borrowings. The interest rate swap has a maturity date of September 30, 2029 and effectively converts the Company's variable interest rate obligation to a fixed interest rate obligation. The interest rate swap had an aggregate notional amount of 4.2 billion rupees as of December 31, 2025 and December 31, 2024. The aggregate effective interest rate of the swap as of December 31, 2025 and December 31, 2024 was 8.25%.

The fair value of the interest rate swap contract was a liability balance of $1.0 million as of December 31, 2025 which was recorded in Accrued liabilities within the consolidated balance sheet. The fair value of the interest rate swap contract was $0.5 million as of December 31, 2024 which was recorded in Accrued liabilities within the consolidated balance sheet.

|  | $3.5 | $(1.2) |  | $1.2 | $2.1 |

---

*<u>Net Investment Hedges</u>*

The Company uses foreign currency denominated intercompany debt and third-party foreign currency forward contracts to hedge the exposure to a portion of the Company's net investments in certain non-U.S. subsidiaries against the effect of exchange rate fluctuations on the translation of foreign currency balances to the U.S. dollar. For the derivative instruments that are designated and qualify as net investment hedges, gains and losses are reported in other comprehensive loss where they offset gains and losses recorded on the Company's net investments in its non-U.S. subsidiaries. These hedges are determined to be effective. The Company recognized $8.8 million of after-tax losses and $2.3 million of after-tax gains associated with hedges of a net investment in non-U.S. subsidiaries in currency translation adjustment in other comprehensive income in 2025 and 2024, respectively.

The contractual amount of the Company's foreign currency denominated intercompany debt that are designated as net investment hedge was 1.5 billion RMB as of both December 31, 2025 and December 31, 2024. The fair value of the net investment hedges was zero as of both December 31, 2025 and December 31, 2024.

**14. Income Taxes (continued)**

The provision for income taxes differs from the U.S. federal statutory rate due to the following items:

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
| <u>Years ended December 31</u> | 2025 | 2025 | 2024 | 2024 | 2023 | 2023 |

|  | $168.9 | 23.6% | $167.4 | 23.9% | $176.9 | 24.1% |

---

<sup>(1)</sup> The state and local jurisdictions that contribute to the majority (greater than 50%) of the tax effect in this category include California, Florida, Illinois, Massachusetts, Maryland, New Jersey, New York and New York City for 2025, California, Illinois, Maryland, Michigan, New Jersey, New York, Pennsylvania and Tennessee for 2024 and California, Florida, Illinois, Massachusetts, New Jersey, New York, Pennsylvania and Tennessee for 2023.

Components of earnings before income taxes were as follows:

---

| | | | |
|:---|:---|:---|:---|
| <u>Years ended December 31 (dollars in millions)</u> | 2025 | 2024 | 2023 |
| **U.S.** | $586.0 | $577.2 | $596.4 |
| **International** | 129.1 | 123.8 | 137.1 |
|  | $715.1 | $701.0 | $733.5 |

---

The cash taxes paid by the Company were as follows:

---

| | | | |
|:---|:---|:---|:---|
| <u>Years ended December 31 (dollars in millions)</u> | 2025 | 2024 | 2023 |
| **Federal** | $119.2 | $136.1 | $134.8 |
| **State** | 21.7 | 28.2 | 25.7 |

| &nbsp;&nbsp;Other foreign jurisdictions | 3.6 | 3.7 | 2.4 |
|  | $165.2 | $187.7 | $189.5 |

---

Undistributed earnings of the Company's foreign subsidiaries amounted to $633.1 million at December 31, 2025. The Company had $4.8 million accrued for its estimate of withholding taxes due upon repatriation of approximately $93.0 million of foreign earnings it considers not permanently reinvested as of December 31, 2025. The Company considers $540.1 million of the total undistributed earnings to be permanently reinvested as a result of various factors including imposition of statutory restrictions at certain jurisdictions that prohibit the repatriation of a portion of the earnings. Accordingly, no provision for state, local and foreign withholding income taxes has been provided thereon. Upon repatriation of those earnings, in the form of dividends or otherwise, the Company would be subject to state and local taxes, and withholding taxes payable to the various foreign countries. The Company expects to be able to take a 100 percent dividend received deduction to offset any US federal income tax liability. Determination of the amount of unrecognized state and local deferred income tax liability and associated foreign withholding taxes is not practicable due to the complexities associated with its hypothetical calculation.

**14. Income Taxes (continued)**

The tax effects of temporary differences of assets and liabilities between income tax and financial reporting are as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
| <u>December 31 (dollars in millions)</u> | 2025 | 2025 | 2024 | 2024 |

|  | $114.9 | $137.6 | $98.3 | $111.9 |
| **Net liability** |  | $22.7 |  | $13.6 |

---

The Company believes it is more likely than not that it will realize its net deferred tax assets through the reduction of future taxable income. The Company considered historical operating results in determining the probability of the realization of the deferred tax assets.

A reconciliation of the beginning and ending amounts of tax loss carryovers, credit carryovers and valuation allowances is as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | Net Operating Losses and Tax Credits | Net Operating Losses and Tax Credits | Valuation Allowances | Valuation Allowances |
| <u>December 31 (dollars in millions)</u> | 2025 | 2024 | 2025 | 2024 |
| **Beginning balance** | $9.7 | $12.3 | $6.1 | $11.7 |
| **Change in balance** | 13.0 | (2.6) | 4.3 | (5.6) |
| **Ending balance** | $22.7 | $9.7 | $10.4 | $6.1 |

---

The Company has foreign net operating loss carryovers that expire in 2026 through 2031, with some net operating losses being carried forward indefinitely and state and local net operating loss carryovers that are carried forward indefinitely.

A reconciliation of the beginning and ending amount of unrecognized benefits is as follows:

---

| | | |
|:---|:---|:---|
| <u>(dollars in millions)</u> | 2025 | 2024 |
| **Balance at January 1** | $16.2 | $17.2 |
| **Change to tax positions from prior years** | (3.2) | (1.0) |
| **Balance at December 31** | $13.0 | $16.2 |

---

The amount of unrecognized tax benefits that, if recognized, would affect the effective income tax rate is $4.9 million. The Company recognizes potential interest and penalties related to unrecognized tax benefits as a component of income tax expense. At December 31, 2025, there was an immaterial amount of interest and penalties accrued. The Company anticipates that there will not be a material decrease in the total amount of unrecognized tax benefits in 2026. The Company's U.S. federal income tax returns and its U.S. state and local income tax returns are subject to audit for the years 2022-2025 and 2010-2025, respectively. The Company is subject to examinations in foreign tax jurisdictions for the years 2019-2025. If the examinations at certain foreign tax jurisdictions are resolved unfavorably, there could be additional assessments imposed by the relevant authorities.

**15. Commitments and Contingencies**

*Environmental Contingencies* 

The Company is a potentially responsible party in judicial and administrative proceedings seeking to clean up sites which have been environmentally impacted. In each case, the Company has established reserves, insurance proceeds and/or a potential recovery from third parties. The Company believes any environmental claims will not have a material effect on its financial position or results of operations.

*Product Liability*

The Company is subject to various claims and pending lawsuits for product liability and other matters arising out of the conduct of the Company's business. For product liability claims, the Company self insures a portion of its product liability loss exposure. The Company has established reserves and insurance coverage that it believes are adequate to cover incurred claims. For the years ended December 31, 2025 and 2024, the Company had $125 million of product liability insurance for individual losses in excess of $7.5 million. At December 31, 2025 and 2024, the reserve for product liability was $26.6 million and $26.3 million, respectively. The Company periodically reevaluates its exposure on claims and lawsuits and makes adjustments to its reserves as appropriate. The Company believes, based on current knowledge, consultation with counsel, adequate reserves and insurance coverage that the outcome of such claims and lawsuits will not have a material adverse effect on the Company's financial position, results of operations or cash flows.

*Purchase Obligations*

The Company utilizes blanket purchase orders to communicate expected annual requirements to certain suppliers. Requirements under blanket purchase orders generally do not become committed until several weeks prior to the scheduled unit production. The purchase obligations the Company considers firm as of December 31, 2025, is $211.7 million, most of which will be ordered in 2026.

*Inventory Repurchase Arrangements*

The Company maintained a commercial relationship with a supply-chain service provider (the Provider) in connection with the Company's business in China. In this capacity, the Provider offered order-entry, warehousing and logistics support. The Provider also offered asset-backed financing to certain of the Company's distributors in China to facilitate their working capital needs. To facilitate its financing support business, the Provider collateralized lending facilities in place with multiple Chinese banks under which the Company agreed to repurchase inventory if both requested by the banks and certain defined conditions are met, primarily related to the aging of the distributors' notes.

The Provider is required to indemnify the Company for any losses the Company would incur in the event of an inventory repurchase under these arrangements. Potential losses under the repurchase arrangements represent the difference between the repurchase price and net proceeds from the resale of product plus costs incurred in the process, less related distributor rebates. As of December 31, 2025, the Company terminated the arrangement with the Provider. Existing loan balances will be paid down throughout 2026 with no new loans offered.

Before considering any reduction of distributor rebate accruals of $1.9 million and $2.0 million as of December 31, 2025 and December 31, 2024, respectively, and from the resale of the related inventory, the gross amount the Company would be obligated to repurchase, which would be contingent on the default of all of the outstanding loans, was approximately $2.1 million and $2.9 million as of December 31, 2025 and December 31, 2024, respectively. The Company's reserves for estimated losses under repurchase arrangements were immaterial as of December 31, 2025 and December 31, 2024.

**16. Operations by Segment**

The Company is comprised of two reporting segments: North America and Rest of World. The Rest of World segment is primarily comprised of China, India, and Europe. Both segments manufacture and market comprehensive lines of residential and commercial gas and electric water heaters, boilers, tanks and water treatment products. Both segments primarily manufacture and market in their respective regions of the world.

The Company's Chief Executive Officer (CEO) is the Chief Operating Decision Maker (CODM). The CODM allocates resources and makes operating decisions based on the financial information presented by the two reporting segments. The measures regularly reviewed by our CODM include segment sales, earnings, and segment margin. Segment earnings, defined by the Company as earnings before interest expense, taxes, corporate expense, and corporate research and development expenses, were used to measure the performance of the segments. Our CODM uses these financial measures to evaluate and allocate capital and company resources as critical determinants of segment performance.

The accounting policies of the reportable segments are the same as those described in the "Summary of Significant Accounting Policies" outlined in Note 1 - Organization and Significant Accounting Policies.

**17. Subsequent Events** 

On January 6, 2026, the Company completed the acquisition of LVC Holdco LLC ("Leonard Valve"). The transaction was completed for $470.0 million, subject to customary adjustments. The all-cash transaction is valued at approximately $412.0 million after adjusting for estimated tax benefits and was funded with cash borrowed under a new credit agreement. The Company has not completed the analysis of identifying and estimating the fair value of identifiable intangible assets acquired. We anticipate preparing a preliminary allocation of the purchase consideration to the assets acquired and liabilities assumed by the end of the second quarter of fiscal 2026. The measurement period for the valuation of net assets acquired ends as soon as information on the facts and circumstances that existed as of the acquisition date becomes available, but not to exceed 12 months following the acquisition date. Adjustments in purchase price allocations may require a change in the amounts allocated to net assets acquired during the periods in which the adjustments are determined.

On January 29, 2026, the Company identified a compromise to a portion of the Ashland City, Tennessee facility roof structure due to a severe ice and snow weather event. For safety purposes, production has been halted temporarily in the area of the facility impacted while remediation activities are underway. The Company has shifted certain production activities to other facilities to address the temporary impact. The Company has insurance coverage for the repair of the assets that were impacted and is working closely with its insurance carrier and claims adjusters to ensure financial recovery due to the event. The Company's insurance policies also provide business interruption coverage, including lost profits, and the reimbursement of other expenses and costs to be incurred relating to the damages and losses suffered. The Company's evaluation of the situation and associated remediation activities is ongoing. As of the date of this filing, the Company does not expect the event to result in a material impact on its financial results.

**<u>ITEM 9A – CONTROLS AND PROCEDURES</u>**

**Evaluation of Disclosure Controls and Procedures**

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended ("the Exchange Act")) as of the end of the period covered by this report. Based on the evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period our disclosure controls and procedures are effective in recording, processing, summarizing, and reporting, on a timely basis, information required to be disclosed by us in the reports that we file or submit under the Exchange Act, and that information is accumulated and communicated to the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely discussions regarding required disclosure.

**Management Report on Internal Control Over Financial Reporting**

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)). The Company's internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our internal control over financial reporting based on the Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, our management has concluded that, as of December 31, 2025, our internal control over financial reporting was effective.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Ernst & Young LLP, an independent registered public accounting firm, has audited our consolidated financial statements and the effectiveness of internal controls over financial reporting as of December 31, 2025 as stated in their report which is included herein.

**Changes in Internal Control Over Financial Reporting**

There have been no changes in the Company's internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)) during the year ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**<u>ITEM 9B – OTHER INFORMATION</u>**

During the three months ended December 31, 2025, none of our directors or Section 16 officers adopted or terminated a "Rule 10b5-1trading arrangement" or "non-Rule 10b5-1 trading arrangement," as each term is defined in Item 408(a) of Regulation S-K.

**<u>ITEM 9C – DISCLOSURE REGARDING FOREIGN JURISDICTIONS THAT PREVENT INSPECTIONS</u>**

**Report of Independent Registered Public Accounting Firm**

To the Stockholders and the Board of Directors of A. O. Smith Corporation

**Opinion on Internal Control Over Financial Reporting** 

We have audited A. O. Smith Corporation's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, A. O. Smith Corporation (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of earnings, comprehensive earnings, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and financial statement schedule listed in the Index at Item 15(a) and our report dated February 10, 2026 expressed an unqualified opinion thereon.

**Basis for Opinion** 

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

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

**Definition and Limitations of Internal Control Over Financial Reporting** 

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

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

If you are aware of any material nonpublic information, you may not trade (buy or sell), or engage in any other transaction with respect to, any of our securities or take part in any action to use the information until it stops being nonpublic.

It is also the policy of A. O. Smith Corporation that it will not engage in transactions in its securities while aware of material nonpublic information relating to A. O. Smith Corporation or its securities, except if such information is disclosed to the counterparty to such transaction.

<u>Rule 10b5-1 Plans</u>

Rule 10b5-1 of the Securities Exchange Act of 1934 provides a defense from insider trading liability. To be eligible to rely on this defense, a person must enter into a Rule 10b5-1 plan for transactions in company securities that meets certain conditions specified in the Rule (a "10b5-1 Plan"). If the plan meets the requirements of Rule 10b5-1, company securities may be purchased or sold without regard to certain insider trading restrictions. To comply with this policy, a 10b5-1 Plan must be approved by the General Counsel and meet the requirements of Rule 10b5-1 as discussed further below.

In general, a 10b5-1 Plan must be entered into in good faith at a time when the person entering into the plan is not aware of material nonpublic information regarding our company. Rule 10b5-1 (a) requires a person (other than a director or officer, for whom it is at least 90 days) wait to begin trading under a 10b5-1 Plan until 30 days after the adoption of the plan, (b) generally prohibits a person from having more than one plan in place at the same time and (c) restricts persons from relying on a single-trade plan more than once during any 12-month period. Once the 10b5-1 plan is adopted, the person must act in good faith with respect to the plan and not exercise any influence over the amount of securities to be traded, the price at which they are to be traded or the date of the trade. The 10b5-1 plan must either specify the amount, pricing and timing of transactions in advance or delegate discretion on these matters to an independent third party.

<u>Preclearance Requirement for Transactions</u>

**All directors, officers and key employees (who are notified they are subject to this preclearance requirement) must notify the General Counsel and the Chief Financial Officer in writing (by electronic mail or otherwise) before any proposed purchase or sale of, or other transaction with respect to, our stock. The approval of both the General Counsel and the Chief Financial Officer is required for any proposed trade or transaction.** An electronic stock approval process is available on AOSNet. Once the director, officer or key employee completes the electronic form, it is automatically routed to the General Counsel and the Chief Financial Officer, and the individual is electronically notified when the process is complete. Clearance will normally be given for a period of fifteen (15) calendar days unless a shorter period is stated and unless the person given clearance is aware of undisclosed material information.

Additionally, directors, officers and anyone who beneficially owns 10% or more of A. O. Smith securities must timely report any changes in their ownership under Section 16 of the Exchange Act by filing a Form 4 with the SEC before the end of the second business day following execution of the transaction. **Contact the General Counsel or Wendy Grant, Supervisor Law Department Administration at wgrant@aosmith.com or 414-359-4147, before trading or engaging in other transactions in our securities to ensure that the transaction is reported timely to the SEC.** 

If you are subject to these preclearance requirements and you wish to trade pursuant to a 10b5-1 Plan, you must obtain the approval of the General Counsel prior to entering into the 10b5-1 Plan. The General Counsel, or his or her designee, must review the 10b5-1 Plan for compliance with this Policy. In addition to the requirements for a 10b5-1 Plan set forth above under "Rule 10b5-1 Plans":

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• You may only enter into or amend a 10b5-1 Plan during an open trade window.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For directors and officers, the 10b5-1 Plan must also include a representation certifying that they are not aware of material nonpublic information about us and are adopting the plan in good faith and not as a scheme to evade the prohibitions of Rule 10b-5.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For directors and officers, the first trade may not occur under a 10b5-1 plan until the later of 90 days after the adoption of the plan or two business days following the disclosure of our financial results in a Form 10-Q or Form 10-K relating to the quarter in which the plan was adopted, subject to a maximum of 120 days after adoption of the plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Unless expressly approved by the General Counsel and compliant with Rule 10b5-1, you may have only one 10b5-1 Plan in effect at a time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Any amendment to a 10b5-1 Plan will be treated as a termination of an existing 10b5-1 Plan and the entry into a new 10b5-1 Plan. Accordingly, the terms of any amendment must be approved in accordance with the terms of this Policy and must otherwise comply with the terms of this Policy as if the amendment were a new 10b5-1 Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If you desire to terminate a 10b5-1 Plan, you must consult with the General Counsel prior to terminating the 10b5-1 Plan.

Any advice provided by the General Counsel, or his or her designees, a proposed purchase, sale, gift or other transfer of our securities will relate solely to pre-clearance and the restraints imposed by law and will not constitute legal advice or advice regarding the investment or tax aspects of any transaction.

<u>All Other Employees</u> 

Other employees are not required to obtain pre-clearance of trades or transactions in our stock; however, if you have material nonpublic information, you may not conduct transactions in our stock. You should contact the Chief Financial Officer or General Counsel if you are uncertain as to whether you are restricted from trading or engaging in other transactions at any time or if you would like to discuss whether you are aware of material nonpublic information.

<u>No-Trade Window Periods</u>

Any director, officer or key employee (who is notified they are subject to no-trade window periods) is prohibited from trading, or engaging in other transactions with respect to, any of our securities during designated no-trade window periods. The no-trade window periods begin on the 10<sup>th</sup> day of the month prior to the month of the release of annual or quarterly financial results and continue through the 2<sup>nd</sup> business day after the release of the financial results, inclusive of the day of the press release. A copy of the current no-trade window calendar may be found on AOSNet. We may also impose special no-trade windows or blackout periods, as determined and announced to relevant persons by the General Counsel, during which the persons notified will be prohibited from purchasing, selling, gifting or otherwise transferring our securities. If you are so notified by the General Counsel, you should not disclose to others the fact of such suspension of trading.

<u>Hedging, Pledging and Certain Trading Prohibited</u>

You must not enter into transactions that hedge or pledge our securities. Without limitation, the prohibition on hedging includes the purchase of any financial instruments (including prepaid variable forward contracts, equity swaps, collars, and exchange funds), or otherwise engaging in transactions, that hedge or offset, or are designed to hedge or offset, any decrease in the market value of our securities.

Under this Policy, you should not engage in any short-term or speculative transactions involving our securities, such as short sales, sales against the box, buying or selling puts or calls, trading in options, or trading in securities on a short-term basis.

**Contact the General Counsel with any questions regarding these prohibitions.**

<u>Policy and Insider Trading Prohibition Applicable to 401(k) and Dividend Reinvestment Plans</u>

This Policy also prohibits making changes to investment elections of our stock in an A. O. Smith Profit Sharing Retirement Plan (401(k) Plan) or making changes to plan participation decisions in A. O. Smith's Dividend Reinvestment Plan (DRP) while you are aware of material nonpublic information.

If you wish to change your investment election in our stock in the 401(k) Plan or your participation and plan decisions in the DRP and you are subject to a preclearance requirement for transaction in our stock described above, **you must make the changes during an open trade window and you must be precleared by the General Counsel and Chief Financial Officer as described above.**

<u>Prohibition on Gifts While Aware of Material Nonpublic Information</u>

This Policy also prohibits you from making a gift of our stock while you are aware of material nonpublic information relating to us.

------

<u>Prohibition on Insider Trading of other Companies</u>

This Policy also applies to material nonpublic information about any other company (including our customers or our suppliers), which you may gain as an employee, and transactions in the securities of such other companies. If, in the course of working for us, you become aware of material nonpublic information about a company with which we do business, such as our customers and suppliers, or that is involved in a potential transaction or business relationship with us, you may not engage in transactions in that company's securities until the information becomes public or is no longer material.

<u>Board of Directors Approval and Insider Trading Compliance Policy Coordinator</u> 

The Board of Directors has approved our Insider Trading Compliance Program and directed that its provisions be implemented and maintained as part of our commitment to compliance with applicable federal and state insider trading laws and regulations.

To ensure compliance with this Policy, we have designated Paul J. Jones, Senior Vice President, General Counsel and Chief Compliance Officer, as the Program Coordinator. The Program Coordinator is responsible for developing and implementing appropriate methods for monitoring compliance with this Policy. If you have any questions about your responsibilities and obligations under this Policy or become aware of any violations, even accidental violations of this Policy, you should contact the Program Coordinator at (414) 359-4210.

Violations

Violation of this policy could result in both civil and criminal penalties, including fines and jail sentences for you, for A. O. Smith and for the person who trades based upon a tip. You can incur penalties for such violations by tipping information to others, even if you do not personally profit from the other person's actions.

Violators of this policy will be appropriately disciplined, up to and including termination of employment.

Policy Owner/Contact

A. O. Smith's General Counsel is responsible for implementation of this policy.

Date of Next Review

A. O. Smith's General Counsel will direct periodic risk assessments and reviews of our operations and the effectiveness of this Policy. This Policy is subject to audit by the Legal Department, the Finance Department, and the Board of Directors. This Policy is also subject to amendment, as determined by A. O. Smith's General Counsel.
