STOCK TRANSFER AGENT, DIVIDEND REINVESTMENT AGENT (FOR BOTH CL ASSES OF STOCK) EQ Shareowner Services 1110 Centre Pointe Curve, Suite 101 Mendota Heights, MN 55120 800-468-9716 651-450-4064 www.shareowneronline.com MARCH 2022 LETTER TO SHAREHOLDERS Dear Shareholders: The past year has been a test of our flexibility, ingenuity and tenacity. It was a challenge I am proud to say the A. O. Smith team met head-on and, frankly, exceeded anyone’s expectations in an unprecedented year. A. O. Smith’s record-setting financial performance in 2021 reflects the dedication, resilience and hard work of our more than 13,700 talented employees. We measure our success by how well we create value for all stakeholders and deliver on our promise to customers, employees and suppliers. I couldn’t be prouder of how our team came through over the past 12 months. We delivered record sales of $3.5 billion, up 22% year-over-year driven by inflation-related pricing actions and continued strong demand. Higher volumes led to net earnings of $487.1 million or $3.02 per share, which is a 42% increase in EPS compared to last year. Free cash flow last year was $566 million, and our debt-to-capital ratio was 9.7% at the end of 2021. Our strong free cash flow and solid balance sheet allow us to focus on capital allocation priorities and return capital to our shareholders, and for the 30th consecutive year, we increased our dividend to shareholders. We also repurchased approximately five million shares of common stock for a total of $366.5 million in 2021. Navigating through component shortages, logistics bottlenecks and rapid inflation in materials and transportation costs required swift and creative thinking. Thanks to a tremendous effort led by our procurement and operations teams, we were able to manage our supply chain and solidify manufacturing lead times, which were keys to bringing the year to a strong close and positioned us well as we enter 2022. Kevin Wheeler, Chairman, President and Chief Executive Officer Acquisitions and leveraging organic growth in all our businesses are priorities for A. O. Smith, and we took advantage of opportunities to expand our presence in both the water heater and water treatment marketplaces. In October, we welcomed Canada-based Giant Factories to the A. O. Smith family. A manufacturer of residential and commercial water heaters with over 75 years of experience, Giant Factories fits perfectly with our core North America water heater business. This acquisition allows us to expand in existing markets and adds to our sustainability efforts, as most of Giant’s water heaters are fueled by renewable energy sources. We also acquired Master Water Conditioning Corporation, a water treatment company based in Pennsylvania offering residential, commercial and light industrial products and systems to address a wide range of water quality issues. As consumers remain focused on the importance of reliable, clean drinking water, we continue to seek opportunities to further expand our presence in this segment. A. O. Smith prides itself on being an industry leader committed to innovation through research and development of efficient technologies and environmentally sustainable products to heat and treat water. Sustainability is an integral part of our strategy. Throughout 2021, we made investments in our facilities to conserve and reduce water, gas and electricity consumption as we continue to push toward our goal of reducing greenhouse gas emissions 10% by 2025. While we look for ways to balance the reduction of greenhouse gases with new product innovation and increased production capacity, I am confident we will meet our reduction goals and expand our sustainability efforts. As we look to the future, we remain confident in our ability to capitalize on opportunities as we continue to execute our strategy. Since 1874, A. O. Smith has adhered to a set of values rooted in integrity, innovation and customer satisfaction, one of which is that we will achieve profitable growth to ensure our future success. Rest assured that our dedication to producing high quality products for customers throughout the world will continue, without sacrificing our commitment to profitable returns. Sincerely, Kevin J. Wheeler Chairman, President & Chief Executive Officer INNOVATIVE SOLUTIONS KEY TO THRIVING IN 2021 At A. O. Smith, the inventive spirit is part of our DNA. Whether pioneering new technologies with a focus on the future or reengineering our global processes to overcome unforeseen challenges, pursuing innovative solutions to tough problems is inherent in everything we do. Throughout 2021, unprecedented disruptions to the global supply chain wreaked havoc on industries around the world. Despite the challenges, we resolved to get our essential water heating and water treating products manufactured and delivered to our customers. To achieve this, we turned to our greatest resource—our people—and formed cross-functional teams with employees from procurement, engineering, operations, manufacturing, sales, marketing and customer service. These teams came together to focus on a single objective: find ways to keep manufacturing our products with the highest levels of quality to meet customer demand. Maintaining an in-flow of raw material, parts and components required agile navigation of constant and significant logistical challenges. Our teams identified and vetted new suppliers, assisted existing suppliers in sourcing the materials needed to produce our parts and coordinated air shipments from several suppliers due to extensive delays in ocean freight. Paired with high demand, the uncertainty of the supply chain created elevated order patterns for many of our customers. Combining innovative processes and teamwork, our teams worked with each wholesale partner to analyze its historical buying patterns, project real demand, align with our production capacity and set achievable timeframes for delivery. In a year when manufacturers in nearly every sector were falling further and further behind, our plants consistently met delivery deadlines, earning praise from customers large and small. Our efforts to continuously improve in areas of environmental, social and governance activities are a testament to one of our core values: A. O. Smith will be a good citizen. In January, we issued our second corporate responsibility and sustainability report with a commitment to a 10% reduction in the Company’s global greenhouse gas (GHG) emissions by 2025. In September, we invited states, policymakers, utilities, installers and consumers to employ our new analytical tool in charting the course to meet GHG reduction goals for the future. Outlined in our white paper Electrification of Water and Space Heating in Buildings, the tool uses proprietary energy use data analysis to provide a pragmatic roadmap to reducing GHG emissions resulting from water and space heating. In our 148th year as in our first, A. O. Smith has continued to evolve to meet and exceed everchanging conditions through the thoughtful application of creativity, passion and innovation. Managing the stresses of the present did not distract us from our commitment to our future. As we have since our founding, our research and development engineers created industry- changing new products and relentlessly pursued improvements to our existing product portfolio. With sustainability, efficiency and connectivity top of mind for customers, our global teams continued to push the envelope on product innovations. As an industry leader in offering solutions to reduce carbon outputs, we worked to incorporate new IoT technology and advanced sensors to optimize overall performance and efficiency and extend product lifecycles. In June, we unveiled the Lochinvar-branded CREST® with Hellcat™ Combustion Technology Boiler, featuring an O2 sensor and SMART TOUCH™ operating control. In what we believe is the first of its kind, CREST with Hellcat identifies changing environmental conditions and adapts automatically, ensuring the unit runs at peak performance without the need to make manual adjustments. Across an eight-model product line from 999,000 to 6.0 million Btu/ hour, CREST with Hellcat is rated to achieve up to 96.2% thermal efficiency. In addition to optimizing efficiency, a new unit can be up and running in less than an hour using the intuitive on-screen Commissioning Wizard.

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. Our Rest of World segment is primarily comprised of China, Europe and India. 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. NORTH AMERICEE ACC We serve residential and commercial end markets in North America with a broad range of products including: Water heaters. Our residential and commercial water heaters come in sizes ranging from 2.5 gallon (point-of-use) models to 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. In 2021, we further expanded our market presence and product offerings with our acquisition of Giant Factories, Inc., (Giant) a Canada-based manufacturer of residential and commercial water heaters. Typical applications for our water heaters include residences, restaurants, hotels and motels, office buildings, laundries, car washes, schools and small businesses. t Boilers. Our residential and commercial boilers range in size from 45,000 British Thermal Units (BTUs) to 6.0 million BTUs. Our boilers are primarily used in space heating applications for residences, hospitals, schools, hotels and other large commercial buildings. tt Water treatment products. With the acquisition of Aquasana, Inc. (Aquasana) in 2016 we entered the water treatment market. We expanded our product offerings with the acquisitions of Hague Quality Water International (Hague) in 2017, Water- Right, Inc. (Water-Right) in 2019 and Master Water Conditioning Corporation (Master Water) in 2021. Our 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 and point-of-use carbon and reverse osmosis products. We also offer a complete line of food and beverage filtration products. Typical applications for our water treatment products include residences, restaurants, hotels 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 portions 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 more than 1,100 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 the U.S. 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, the remainder of our Lochinvar branded products are distributed through wholesale channels. We sell our A. O. Smith branded water treatment products through Lowe's, Amazon, and our wholesale distribution channels. Our Aquasana branded products are primarily sold directly to consumers through e-commerce as well as online retailers including Amazon and through other retail chains. Our water softener branded products and problem well water solutions, which include Hague, Water-Right, and Master Water are sold through water quality dealers. Our water softener products are also sold through 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 3 with a short payback period through energy savings. We offer residential heat pump, condensing tank-type and tankless water heaters in North America, as well as other higher efficiency water heating solutions to round out our energy-efficient product offerings. In addition, during 2021 we launched a commercial heat pump water heater to align with greenhouse gas emission reduction trends across the country. We sell our products in highly competitive markets. We compete in each of our targeted market segments based on product ity, quality of products and services, advanced technologies, energy efficiency, maintenance costs and price. design, reliabila 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 WORLDRR We have operated in China for more than 25 years. In that time, we have established A. O. Smith brand recognition in the residential and commercial markets. 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 leading suppliers of water heaters and reverse osmosis water treatment products to the residential market in China in dollar terms. We manufacture and market residential water treatment products, primarily incorporating reverse osmosis technology, and commercial water treatment products. We also design and market range hoods and cooktops in China. We sell our products in approximately 13,000 points of sale in China, approximately 5,800 are retail outlets in tier one and tier two cities of which over 2,000 exclusively sell our products. We also sell our products through e-commerce channels. 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. Our primary competitors in China in the water heater market segment are Haier and Midea, which are Chinese companies, as well as Rinnai. Our principal competitors in the water treatment market are Angel, Midea, Truliva, and Xiaomi. In India, we compete with Racold, Bajaj and Havells in the water heater market and Eureka Forbes, Kent and Hindustan Unilever in the water treatment market. In addition, we sell water heaters in the European and Middle Eastern markets and water treatment products in Hong Kong, Turkey and Vietnam, all of which combined comprised less than 11 percent of total Rest of World sales in 2021. RAW MATERIALS Raw materials for our manufacturing operations, primarily consisting of steel, are generally availablea in adequate quantities, however, the global health pandemic and disruptions in the commercial transportation network have stressed the availability of certain raw materials. There has been volatility in steel costs over the last several years, particularity in 2021 as the steel pricing tied to price index increased over 100 percent compared to the prior year. A portion of our customers have contractual a steel index. t RESEARCH AND DEVELOPMENT To improve our competitiveness by generating new products and processes, we conduct research and development at our e Technology Center in Milwaukee, Wisconsin, our Global Engineering Center in Nanjing, China, and our operating r Corporat locations. Our total expenditures for research and development in 2021, 2020 and 2019 were $94.2 million, $80.7 million and $87.9 million, respectively. PATENTS AND TRADE RR MARKS We own and use in our businesses various trademarks, trade names, patents, trade secrets and licenses. 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 or group of related trademarks, trade names, patents, trade secrets, or licenses. Our trade name is important with respect to our products, particularly in China, India, and the U.S. HUMAN CAPITAL We employed approximately 13,700 employees as of December 31, 2021, primarily non-union. The foundation of how we conduct business and interact with our employees is outlined in the A. O. Smith Corporation Guiding Principles, which were refreshed in 2021, and our Statement of Values. These principles and values help to shapea how we hire, train and treat our employees, emphasizing teamwork and promoting diversity in seeking our objectives. We believe that the critical elements of our effort to attract, retain and develop talent are employee engagement, talent development, a focus on employee safety, and market competitive compensation. 4 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. Survey participation in 2020 was 96 percent, which we believe indicates our employees' willingness to share their perspectives and a commitment to continuous improvement. We will conduct the survey again in 2022. We provide all employees with a wide range of professional development experiences, both formal and informal, to help them achieve their full potential. 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. Globally, all office and professional employees have a formal performance review and development plans with a focus on learning by doing. It is expected that managers work closely with their employees to ensure performance feedback and development discussions take place on a regular basis. 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 awarded annually the Lloyd B. Smith President's Safetyt Award, which acknowledges an A. O. Smith facility that demonstrates the most improvement over one year in the area of workplace safety.t We provide what we believe is a robust total compensation program designed to be market-competitive and internally equitablea to attract, retain, motivate and reward a high-performance workforce. Regular internal and external analysis is performed to ensure this 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, tuition assistance, among others. BACKLOG Due to the short-cycle nature of our businesses, none of our operations sustain significant backlogs. GOVERNMENT REGULATIONS AND ENVIRONMENTAL MATTERS Our operations, including the manufacture, packaging, label ing, 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 Safetyt 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. Similar laws and regulations have been adopted by government authorities in other countries in which we manufacture, distribute, and sell our products. a t In addition, our operations are subject to federal, state and local environmental laws. We are subjeu ct to regulations of the U.S. Environmental Protection Agency and the Occupational Health and Safetyt Administration and their counterpart state agencies.

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 ■ Our operations couldll be adversely impacted by material and component price volatilitytt and availability,yy as well as supplier concentration a The market prices for certain materials and components we purchase, primarily steel, have been volatile. U.S. steel index prices alone increased over 100 percent in 2021. We have also experienced inflation related increases in our transportation costs. In addition, some components are subject to long lead times. Disruptions to the commercial transportation network, ity and port congestion, have increased supplier delivery times for materials including limited container and trucking capac and components to our facilities and, in some cases, our ability to timely ship to customers. We engage in ongoing communications with our suppliers to identify and mitigate risk of potential disrupti ons and to manage our material and component inventory levels. Significant increases in the cost of any of the key materials and components we purchase or delays in their delivery could 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. As a response to cost inflation in materials and components, we announced price increases on water heaters in North America in 2021 that compound to approximately 50 percent. Historically, there has been a lag in our ability to recover increased material costs from customers, and that lag, particularly for the price increases that we implemented in 2021, 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. r ■ The global coronavirus (COVID-19) VV pandemic, or other global public health pandemics, couldll have a material adverse effeff ct on our business, results of operations and financial condition Our business, results of operations and financial condition may be adversely affected if a global public health pandemic, including the current COVID-19 pandemic, interferes with the ability of our employees, suppliers, and customers to perform our and their respective responsibilities and obligations relative to the conduct of our business and operations. The COVID-19 pandemic has significantly impacted economic activity and markets around the world, and it could have a material negative impact on our business and operations in numerous ways, including but not limited to those outlined below: • • • • • The risk that we, or our employees, suppliers or customers may be prevented from conducting business activities for an indefinite period of time, including shutdowns that may be requested or mandated by governmental authorities. Restrictions on shipping products from certain jurisdictions where they are produced or into certain jurisdictions where customers are located. Inability to meet our customers’ needs and achieve cost targets due to increased logistics costs, longer shipment times, and disruptions in our manufacturing and supply arrangements caused by the loss or disruption of essential manufacturing and supply elements, such as raw materials or other finished product components, transportation, lity. workforce or other manufacturing and distribution capabi a t Failure of third parties on which we rely, including our suppliers, distributors, contractors and commercial banks, to meet their obligations to us, or significant disruptions in their ability to do so, which may be caused by their own financial or operational difficul ties, workforce disruptions, or mandated shutdowns by governmental authorities, may adversely impact our operations. ff Significant reductions in demand, particularly for our commercial products, or significant volatility in demand and a global economic recession that could reduce demand for our products, resulting from actions taken by governments, businesses, and/or the general public in an effort to limit exposure to and spreading of such infectious diseases, such as travel restrictions, quarantines, and business shutdowns or slowdowns. In addition, there is risk that the 7 commercial sector, such as the restaurant and hospitality industries in which we have customers, will experience to pre- long-term shifts in consumer behavior which could negatively impact demand or capac pandemic levels. ity and may not returnt a • Manufacturing plant inefficiencies due to safety and preventative health measures that we have implemented in our plants to prevent the spread of COVID-19. • Deterioration of worldwide capita financing to fund our operations and capia tal expenditures. al, credit, and financial markets that could limit our ability to obtain external The extent to which the COVID-19 pandemic, or other outbreaks of disease or similar public health threats, materially and adversely impacts our business, results of operations and financial condition remains uncertain and will depend on future developments. Such developments may include the geographic spread and duration of the virus, periodic surges of the virus, the severity of the virus and the actions that may be taken by various governmental authorities and other third parties in response to the outbreak. In addition, we cannot predict how quickly, and to what extent, normal economic and operating conditions can resume, and the resumption of normal business operations may be delayed or constrained by lingering effects of the COVID-19 pandemic on our suppliers, third-party service providers, and/or customers. a ■ The effeff ctstt of a global and regional economic conditions couldll have a material adverse effeff ct on our business A decline in economic activity, such as recession or economic downturn, in the U.S. and other regions in the world in which we do business, could 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 or political ity. In addition, an increase in price levels generally or in particular industries (such as the recent inflation in steel instabila prices and logistics costs), could result in a consumer shift away from the products we offer, 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. ■ Because approximately 26 percent of our net sales in 2021 were attributabl tt e to China, adverse economic conditions or changes in consumer behavior in China could impact m our business Our sales in China increased 24 percent in local currency in 2021 compared to 2020. Our sales in China were significantly impacted by the COVID-19 pandemic in 2020. We derive a substant ial portion of our sales in China from premium-tier products. Changes in consumer preferences and purchasing behaviors including preferences for e-commerce, weakening consumer confidence and sentiment as well as economic uncertainty, socio-political risks, increased competition from Chinese based companies, and the potential future impact of the COVID-19 pandemic, 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. u ■ Because we participate in marketkk stt that are highly competitive, our revenues and earnings could decline as we respond to competition ff a ity, quality of products and services, advanced technologies, product performanc We sell all of our products in highly competitive and evolving markets. We compete in each of our targeted markets based on product design, reliabila e, 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 rapia d replication of features, benefits, and technologies, and some are increasingly expanding beyond their existing manufacturing or geographic footprints. In North America, the gas tankless portion of the water heating market has for many years increased as a percentage of the overall market. While we have many gas tankless products, our market share for gas tankless products is lower than our market share for the remainder of the water heating market. Further expansion of the gas tankless portion of the North America market, which we believe was approximately 12 percent of the residential market segment in 2021, could have an impact on our operating results. We cannot assure that our products will continue to compete successfully with those of our competitors. There could be new market participants that change the dynamics of those markets 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, all of which could materially and adversely affect our financial condition, results of operations and cash flows. 8 ■ Our business couldll be adversely impacted by changes in consumer purchasing behavior, consumer prefereff nces and technological changes Consumer preferences for products and the methods in which they purchase products are constantly changing based on, among other factors, cost, convenience, environmental and social concerns and perceptions. Consumer purchasing behavior may shift the product mix in the markets we participate in or result in a shift to other distribution channels, including e- commerce, which continues to expand. For example, consumer preferences may shift toward more efficient gas products or electric powered products due to the increased attention on the impact of greenhouse gas emissions on the environment in response to utility incentive programs, or the emergence of state or federal incentives. In addition, technologies are ever changing. Our ability to timely develop and successfully market new products and to develop, acquire, retain and protect property rights is essential to our continued success, but cannot reasonably be assured. It is possible that necessary intellectual we will not be able to develop new technologies, products or distribution channels to align with consumer purchasing behavior and consumer preferences, which could materially and adversely affect our financial condition, results of operations and cash flows. t ■ The occurrence or threat of extraordinary events, including natural disasters, political disruptions, terroristii attacks,kk public healthtt issues, and acts of war, could signi fii cantly disrupt production, or impact consumer spending i As a global company with a large international footprint, we are subject to increased risk of damage or disruption to us and disasters resulting from our employees, facilities, suppliers, distributors, or customers. Extraordinary events, including natural but not limited to climate change, political disruptions, terrorist attacks, public health issues, such as the current COVID-19 pandemic, 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. 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. Any of these disrurr ptiu ons 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. In addition, 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. t Business, Operational, and Strategic Risks ■ We sell our products and operate outside the U.S., and to a lesser extent, rely on importstt and exports, x which may present additional riskskk to our business Approximately 36 percent of our net sales in 2021 were attributablea to products sold outside of the U.S., primarily in China and Canada, and to a lesser extent in Europe and India. We also have operations and business relationships outside the U.S. that comprise a portion of our manufacturing, supply, and distribution. Approximately 6,800 of our 13,700 employees as of December 31, 2021 were located in China. At December 31, 2021, approximately $608 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 instabila 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 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. ity; local labor a a ■ A material loss, cancellation, reduction, or delayl in purchases by one or more of our largest customers couldll harm our business Net sales to our five largest customers represented approximately 41 percent of our sales in 2021. 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 pay or make 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 ity to successfully develop largest customers, any material reduction or delay in sales to these customers, or our inabila 9 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 couldll be adversely affeff cted by a decline in North American new residential construction, a decline in commercial construction or a decline in replac e ement-related volume of water heaters and boilers Residential new construction activity in North America and industry-wide replacement-related volume of water heaters have shown growth which could decline in the future. Commercial construction activity in North America grew in 2021 after declining in 2020. We believe that the significant majori ty of the markets we serve are for replacement of existing products, and residential water heater replacement volume was strong in 2021. Changes in the replacement volume and in the t us. construction market in North America could negatively affecff a ■ An inability to adequatelyll maintain our informat ff ion systems and their security, as well as to protect data and other confideff n ntial informat ion, could adversely affecff t our business and reputat e ion t 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 identifiablea information of our customers, suppliers and business partners, as well as personally identifiablea information about our employees. Our information systems are susceptible to outages due to system failures, cybersecurity threats, failures on the part of third-party disasters, power loss, telecommunications failures, viruses, fraud, theft, malicious information system providers, natural actors or breaches of security. Like many companies, we, and some third parties upon which we rely, have experienced cybersecurity attacks on information technology networks and systems, products and services in the past but, to date, none have resulted in any material adverse impact to our financial condition, results of operations, or cash flows. We may experience them in the future, potentially with increasing frequency from increasingly sophisticated cyber threats that could result in operations failure or breach of security that could lead to disruptions of our business activities, the loss or disclosure of both our and our customers’ financial, product and other confidential information and could result in regulatory actions, litigation and have a material adverse effect on our financial condition, results of operations and cash flows and our reputation. We have a response plan in place in the event of a data breach and we continue to take steps 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. ■ Our international operations are subject to riskskk related to foreigni currencies We have a significant presence outside of the U.S., primarily in China and Canada and to a lesser extent Europe, Mexico, and India, and therefore, hold assets, including $492 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, hyperinflation in some foreign countries or global exchange rate instabila ity or volatility that strengthens the U.S. dollar against foreign currencies. As a result, an increase in the value of the U.S. dollar relative to the local currencies of our foreign markets has had and could have a negative effect on our profitability. In addition to currency translation risks, we incur a currency transaction risk whenever one of our subsidiaries enters into either a purchase or sale transaction using a currency different from the operating subsidiaries’ functional currency. The majoa rity 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 Europe and payroll in Mexico. These risks may hurt 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 defee ctstt 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 liabia lity and recall or retrofitff 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 inabila ity 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. 10 ■ Potential acquisit ii ions couldll use a signif yll icff ant portion of our capital and we may not successfull i ff integrate future acquisit ii ions or operate them profitably or achieve strategice objectives We acquired Giant, a Canada-based manufacturer of residential and commercial water heaters, on October 19, 2021, for $199 million subject to customary adjustments using a combination of cash and debt. We will continue to evaluate potential acquisitions, and we could use a significant portion of our available capita al to fund future acquisitions. We may not be able to successfully integrate Giant or any 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 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 effecff t on our financial condition, results of operations and cash flows. Legal, Regulatory, and Governance Risks ■ Changes in regul e ations or standards could adversely affecff t our business t regulatory and industry standards and requirements related to, among Our products are subject to a wide variety of statutory, ing and safety.t While we believe our products are other items, energy and water efficiency, environmental emissions, label currently efficient, safe and environment-friendly, federal, foreign, state and local governments may adopt laws, regulations and codes that will require a transition to non-fossil fuel based sources of energy production as well as significantly reducing or eliminating the on-site combustion of fossil fuels in the building sector, such as limiting or prohibiting the deliveryrr of gas in new construction. A significant change to regulatory requirements that promote a transition to alternative t natural energy sources as a replacement for gas, or a significant shift in industry standards, could substantially increase manufacturing costs, 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. a ■ We are subject to U.S. and global laws and regulations covering our domestic and international operations that could adversely affecff t 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 u 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 results of operations may be negati e vely impacted by product liability lawsuits ww and claims Our products expose us to potential product liabia lity risks that are inherent in the design, manufacture, sale and use of our product liabia lity insurance, we cannot be certain that we products. While we currently maintain what we believe to be suitablea will be abla e to maintain this insurance on acceptablea terms, that this insurance will provide adequate protection against potential liabia lities or that our insurance providers will be abla e to ultimately pay all insured losses. In addition, we self-iff nsure a portion of product liabia lity 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 signif icff ant goodwill and indefie nite-lived intangible assets and an impairment rr i of our goodwill or indefie nite-lived intangible assets couldll cause a decline in our net worthtt 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 capita alization, 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. 11 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. ■ Our pension plans may require future pension contributi tt ons which couldll limit our flexibility in managing our company The projected benefit obligation liability of our defined benefit pension plans of $842 million exceeded the fair value of the plan assets of $826 million by approximately $16 million at December 31, 2021. U.S. employees hired after January 1, 2010, have not participated in our defined benefit plan, and benefit accruals for the majoa rity of current salaried and hourly employees ended on December 31, 2014. In 2021 our Board of Directors approved the termination of the previously sunset pension plan, with a termination date of December 31, 2021. We filed a determination letter with the IRS regarding the qualification of the plan termination. In 2022, we plan to annuitize the plan's remaining pension liability. We forecast that we will not be required to make a contribution to the plan in 2022, and we do not plan to make any voluntary contributions. However, we cannot provide any assurance that contributions will not be required in the future. Among the key assumptim ons inherent in our actuarially calculated pension plan obligation and pension plan expense are the discount rate and the expected rate of returnt on invested plan assets were to decrease significantly, our pension plan obligations could increase materially. The size of future required pension contributions could result in us dedicating a significant portion of our cash flows from operations to making contributions which could negatively impact our flexibility in managing our company. on plan assets. If interest rates and actual rates of returnt ■ Certain members of the founding familyll of our company and truststt for their benefie t have the abilitytt to influeff nce all mattersrr requiring stockholder l 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, 2021, through the voting trust, these members of the Smith Family own approximately 64.5 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 96.8 percent of the voting power of the outstanding shares of our Class A Common Stock, as a separate class. Due to the difference s 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 transferff their shares. ff ITEM 1B – UNRESOLVED STAFF COMMENTS None. 12 ITEM 2 – PROPERTIES Properties utilized by us at December 31, 2021 were as follows: North America In this segment, we have 19 manufacturing plants located in nine states and two non-U.S. countries, of which 17 are owned directly by us or our subsidiaries and two are leased from outside parties. The terms of leases in effect at December 31, 2021, expire between 2023 and 2025. Rest of World In this segment, we have six manufacturing plants located in four non-U.S. countries, of which four are owned directly by us or our subsidiaries and two are leased from outside parties. The terms of leases in effect at December 31, 2021, expire between 2022 and 2025. Corporate and General p We consider our plants and other physical properties to be suitable, adequate, and of sufficient productive capaa city to meet the requirements of our business. The manufacturing plants operate at varying levels of utilization depending on the type of operation and market conditions. The executive offices of the Company, which are leased, are located in Milwaukee, Wisconsin. ITEM 3 – LEGAL PROCEEDINGS We are involved in various unresolved legal actions, administrative proceedings and claims in the ordinary course of our business involving product liabia lity, property damage, insurance coverage, exposure to asbestos and other substances, patents and environmental matters, including the disposal of hazardous waste. Although it is not possible to predict with certainty the outcome of these unresolved legal actions or the range of possible loss or recovery, we believe, based on past experience, adequate reserves and insurance availability, that these unresolved legal actions will not have a material effeff ct on our financial position or results of operations. A more detailed discussion of certain of these matters appears in Note 16 of Notes to Consolidated Financial Statements.

This number of stockholders of record also does not include stockholders whose shares may be held in trust by other entities. Dividends. Dividends declared on the common stock are shown in Note 11 of Notes to Consolidated Financial Statements appearing elsewhere herein. Stock Repurchases . In 2021, the Board of Directors approved adding 7,000,000 shares of Common Stock to an p existing discretionary share repurchase authority. Under the share repurchase program, the Common Stock may be purchased through a combination of Rule 10b5-1 automatic trading plan and discretionary purchases in accordance with applicable securities laws. The number of shares purchased and the timing of the purchases will depend on a number of factors, including share price, trading volume and general market conditions, as well as working capita al requirements, general business conditions and other factors, including alternative investment opportunities. The stock 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. In 2021, we repurchased 5,087,467 shares at an average price of $72.03 per share and at a total cost of $366.5 million. As of December 31, 2021, there were 3,526,357 shares remaining on the existing repurchase authorization. After a blackout period on share repurchase activity in the third quarter of 2021 related to the Giant acquisition, we resumed our repurchases in early November. On January 25, 2022, the Board of Directors approved adding 3,500,000 shares of common stock to the existing discretionary share repurchase authority. Including the additional shares, we have approxim for repurchase as of the date of the Board of Directors' approval.

Our Rest of World segment is primarily comprised of China, Europe and India. 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 manufacturet and market in their respective region of the world. In January 2020, an outbreak of a novel coronavirus (COVID-19) surfaced in Wuhan, China, which by March 2020 had spread throughout the world and was declared a global pandemic. Since March 2020 and continuing into 2021, we experienced impacts to our business and other markets worldwide. As a result of the COVID-19 pandemic and in support of continuing our manufacturing efforts, we have undertaken numerous and meaningful steps to protect our employees, suppliers, and customers. As we continue to receive guidance from governmental authorities, we adjust our safetyt measures to meet or exceed those guidelines. Our global supply chain management team continued to navigate through supply chain and logistics challenges in 2021. We have seen supply constraints for certain components and raw materials used in our operations, as well as limited container and trucking capac ity, and port congestion and delays. While supply chain issues moderated as we moved into 2022, we remain in close contact with our suppliers and logistics providers to troubleshoot, manage and resolve bottlenecks, as the environment remains unpredictable, particularly with the surge in the Omicron variant of COVID-19. a We seek to continue to grow our core residential and commercial water heating, boiler and water treatment businesses throughout the world. This includes focusing on acquisitions that are related to our core business. Consistent with this strategy, we acquired Giant Factories, Inc. (Giant), a Canada-based manufacturer of residential and commercial water heaters, on October 19, 2021, for $199 million, subject to customary adjustments, using a combination of debt and cash. The acquisition fits squarely in our core capaa bia lities, supple ity and distribution in the region. Giant contributed $22.9 million of sales and approximately $0.01 in earnings per share (EPS) to our results in 2021 and we expect Giant will contribute approximately $0.06-$0.08 to our EPS in 2022. We will also continue to look for opportunities to add to our existing operations in high growth regions demonstrated by our previous introductions of water treatment products in India and range hoods and cooktops in China. ments our presence in Canada and enhances our capac u a t ff In our North America segment, after approximately eight percent growth each year in 2021 and 2020, we expect residential industry water heater volumes will be down approximately two percent in 2022 compared with 2021 as we believe that industry demand will normalize to more historical growth rates. We believe that commercial water heater industry volumes will be flat to slightly down in 2022 compared to 2021 as new construction and replacement installations level off. We expect sales in 2022 will benefit from our 2021 price increases, which had a cumulative effect on our water heater prices of approximately 50 percent. We expect to see a ten percent increase in our sales of boilers in 2022 compared to 2021 due to industry growth of three to four percent, our expectation that the transition to higher-efficiency boilers will continue as well as our new product introductions. We anticipate sales of our North America water treatment products will increase 13 to 14 percent in 2022, compared to 2021, primarily driven by consumer demand for our point of use and point of entry water treatment systems. In our Rest of World segment, after strong growth in 2021, we expect 2022 sales in China to increase approximately five percent in local currency compared with 2021 driven by demand for our residential and commercial water treatment products, including our replacement filters, as well as rangehoods and cooktops. We assume China currency rates will stay at levels similar to 2021. Combining all of these factors, we expect our consolidated sales to increase between 16 and 18 percent in 2022. Our guidance excludes the potential impacts from future acquisitions and assumes the recent surge of the Omicron variant subsides during the first quarter of 2022 and does not have a significant impact on our productivity or significantly impact the end markets that we serve. 19 RESULTS OF OPERATRR IONS In this section, we discuss the results of our operations for 2021 compared with 2020. We discuss our cash flows and current financial condition under “Liquidity and Capita al Resources.” For a discussion related to 2020 compared with 2019, please refer to Item 7 of Part II, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the Year Ended December 31, 2020, which was filed with the United States Securities and Exchange Commission (SEC) on February 12, 2021, and is availablea on the SEC's website at www.sec.gov.

Compared to 2020, which was negatively impacted by the COVID-19 pandemic, our sales increase in 2021 was primarily driven by inflation- related pricing actions and higher water heater, boiler, and water treatment volumes in North America as well as higher sales in China. Our acquisition of Giant added $22.9 million of sales in 2021. In addition, our sales in China were favorabl y impacted by approxi mately $58 million in 2021 compared to 2020, due to the appreciation of the Chinese currency compared to the U.S. dollar. a ff Our gross profit margin in 2021 of 37.0 percent declined compared to 38.3 percent in 2020. The lower gross margin in 2021 was primarily dued to higher steel and other material costs which outpac ed our pricing actions. t Selling, general, and administrative (SG&A) expenses were $701.4 million in 2021 or $41.1 million higher than 2020. The increase in SG&A expenses in 2021 was primarily due to higher advertising, engineering and selling expenses and higher management incentive expenses related to higher earnings compared to 2020. Higher SG&A expenses in 2021 were partially offset by lower spending in China associated with headcount reductions, store closures and other cost-saving measures implemented during 2020. d To align our business to market conditions in 2020, we recognized $7.7 million of pre-tax severance and restructuring expenses. The charges were comprised of $6.8 million severance costs and $0.9 million of other restructuring expenses. These activities are reflected in "severance and restructuring expenses" in the accompanying financial statements. t Interest expense was $4.3 million in 2021, compared to $7.3 million in 2020. The decrease in interest expense in 2021 was primarily due to lower average debt levels. Other income was $20.4 million in 2021 compared to $11.0 million in 2020. The increase in other income in 2021 was primarily due to higher pension and interest income. Pension income in 2021 was $12.0 million compared to $5.1 million in 2020. The service cost component of our pension income is reflected in cost of products sold and SG&A expenses. All other components of our pension income are reflected in other income. Our effective income tax rate was 22.1 percent in 2021, compared with 22.3 percent in 2020. Our lower effective income tax blea rate in 2021 was primarily due to a change in geographic tax impact related to amending a previously filed tax return. the full year of 2022 will be between 23.5 and 24 percent.

The increased sales in 2021 were driven primarily by price increases, largely on water heaters, which were implemented in response to rising material and transportation costs. Higher sales were also driven by increased volumes across all product lines, including $22.9 million of incremental sales from Giant. North America segment earnings were $590.8 million in 2021, an increase of 17 percent compared to segment earnings of $503.5 million in 2020. Segment margins were 23.4 percent and 23.8 percent in 2021 and 2020, respectively. Higher segment earnings in 2021 were primarily due to inflation-related price increases and higher volumes, partially offset by higher material and logistics costs. Segment margin was lower in 2021 primarily due to the rise in costs outpacing pricing actions. In 2020 segment earnings and margin were adversely impacted by certain costs related to the pandemic. Those costs included temporarily moving production from Mexico to the U.S., paying employees during temporary plant shutdowns, proactively and other costs, which were approximately $6.6 million deep cleaning facilities, paying benefits during in 2020.

The increase in 2021 sales was primarily due to growth in our majora product categories in China, including electric and gas tankless water heaters, and residential and commercial water treatment products, including replacement filters. Sales in China were also positively impacted by lower channel inventory reductions in 2021 compared to 2020. Channel inventory levels in China at the end of 2021 were at their lowest level in the last five years. Products with higher selling prices, including super-quiet gas tankless water heaters and water treatment products that deliver filff tered water at a faster flow rate, contributed to sales gains. Sales in India increased approximately 31% compared to 2020, which was significantly impacted by the pandemic. y impacted by approxi a Rest of World segment earnings were $91.4 million in 2021 compared to breakeven in 2020. Segment margin was 8.8 percent in 2021. Compared to 2020, which was significantly impacted by the pandemic, earnings in 2021 increased primarily due to higher volumes in China, which was partially offset by higher employee incentives and brand-building-related advertising costs, as well as the absa ence of the social insurance waivers received in 2020 that did not repeat in 2021. Higher segment -year operating margin of 8.8% was primarily a result of increased operating leverage from higher volumes.

A Our working capita majori , payroll related accruals and lower cash al was driven by higher accounts payablea a balances than 2020, which were partially offset by higher inventory and sales related accounts receivable balances. We repatriated approximately $168 million of foreign cash and marketable securities in 2021 and utilized it to repurchase shares mately $100 million in 2022 and use the proceeds for common stock of our common stock. We expect to repatriate approxi repurchases. a ) Years ended December 31 (dollars in millions) ( Cash provided by operating activities Cash (used in) provided by investing activities Cash used in finff ancing activities 2021 2020 $ 641.1 $ (349.9) (421.0) 562.1 11.8 (374.8) Cash provided by operating activities in 2021 was $641.1 million compared with $562.1 million during 2020.

We expect freeff cash flow to be between $500 million to $525 million in 2022. Free cash flow is a non U.S. Generally Accepted Accounting Principles (GAAP) measure and is described in more detail in the Non-GAAPGG Measures section below.

We project our 2022 capita amortization will be approximately $80 million. During the second quarter of 2021, we renewed and amended our $500 million revolving credit facility, which now expires on April 1, 2026. The renewed and amended facff ility, with a group of nine banks, has an accordion provision that allows it to be increased up to $850 million if certain conditions (including lender approval) are satisfied. Borrowing rates under the facility are determined by our leverage ratio. The 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, 2021 and expect to be in compliance forff the foreff seeablea future. The facility backs up commercial paper and credit line borrowings. At December 31, 2021, we had $50 million outstanding under the facility and an available borrowing capac ity of $450 million. We believe the combination of available borrowing a capac ity and operating cash flows will provide sufficient funds to finance our existing operations for the foreseeable futff ure. a t Our total debt increased by $83.5 million from $113.2 million at December 31, 2020 to $196.7 million at December 31, 2021. The increase in debt balances was due to our acquisition of Giant and repurchases of our common stock. Our leverage, as measured by the ratio of total debt to total capitalization, calculated excluding operating lease liabilities, was 9.7 percent at December 31, 2021, compared with 5.8 percent at December 31, 2020. Our U.S. pension plan continues to meet all funding requirements under ERISA regulations. We were not required to make a contribution to our pension plan in 2021. We forecast that we will not be required to make a contribution to the plan in 2022, and we do not plan to make any voluntary contributions in 2022. For further information on our pension plans, see the Critical Accounting Policies below and Note 13 of Notes to Consolidated Financial Statements. In 2021, our Board of Directors approved adding 7,000,000 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 appli securities laws. The stock 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 2021, we repurchased 5,087,467 shares of our stock at a total cost of $366.5 million. As of December 31, 2021, we had 3,526,357 shares remaining on the share repurchase authority. After a blackout period on share repurchase activity in the third quarter related to the Giant acquisition, we resumed our repurchases in early November. On January 25, 2022, the Board of Directors approved adding 3,500,000 shares of common stock to the existing discretionary share repurchase authority. Including the additional shares, for repurchase as of the date of the Board of Directors' approval. We we have approximately 6.8 million shares availablea cablea a 22 intend to repurchase approximately $400 million of our common stock in 2022 through a combination of 10b5-1 plans and open market purchases. On October 19, 2021, we acquired Giant, a Canada-based manufacturer of residential and commercial water heaters for approximately $199 million, subject to customary adjustments, using a combination of debt and cash. Giant manufactures water heaters at two facilities in Montreal, Canada and sells water heating products under the Giant brand across Canada. Incremental sales of $23 million were realized in 2021, from the date of acquisition. We have paid dividends for 82 consecutive years with annual amounts increasing each of the last 30 years. We paid dividends of $1.06 per share in 2021 compared with $0.98 per share in 2020. We increased our dividend by eight percent in the fourth quarter of 2021, and the five-year compound annual growth rate of our dividend payment is approximately 17 percent. Recent Accounting Pronouncements Refer to Recent Accounting Pronouncementstt in Note 1 of Notes to Consolidated Financial Statements. Critical Accounting Policies Our accounting policies are described in Note 1 of Notes to 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 assumptim ons 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 differff those estimates, and such differences may be material to the financial statements. fromff 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, as well as significant estimates used in the determination of liabilities related to warrantyt activity, product liabia lity and pensions. Various assumptim ons and other factors underlie the determination of these significant estimates. The process of determining significant estimates is fact- specificff 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 Indefie nite-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 performff impairment reviews for our reporting units using a fair-value method based on management’s judgments and assumptim ons. 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 highly judgmental as estimates of future sales, intangible assets become impaired. Any impairment review is, by its nature, 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, 2021. The fair value of each of our reporting units significantly exceeded its carrying value and a 10% decrease in the estimated fair value of our reporting units would not have resulted in a different conclusion. Based on the annual indefinite-lived assets impairment test, we determined there was no impairment of our indefinite-lived assets as of December 31, 2021. rr t Product Warrantytt Our products carry warranties that generally range from one to ten 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 upon warranty loss experience using actual historical failure rates and estimated costs of product replacement. The variabla es used in the calculation of the provision are reviewed at least annually. At times, warranty issues issues as they become may arise which are beyond the scope of our historical experience. We provide for any such warrantyt known and estimablea . While our warrantyt 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, 2021 and 2020, our reserve for product warranties was $184.4 million and $142.3 million, 23 respectively. The increase in our reserve for product warranties in 2021 compared to the prior year was primarily due to increased steel prices and the acquisition of Giant. Product Liability Due to the naturet of our products, we are subject to product liabia lity claims in the normal course of business. We maintain insurance to reduce our risk. Most insurance coverage includes self-insured retentions that vary by year. In 2021, we maintained a self-insured retention of $7.5 million per occurrence with an aggregate insurance limit of $125.0 million. We sh product liabia lity reserves for our self-insured retention portion of any known outstanding matters based on the establia likelihood of loss and our ability to reasonablya resolution of litigation. We make estimates based on available information and our of unsettled matters due to the unpredictable naturet best judgment after consultation with appropriate advisors and experts. We periodically revise estimates based upon changes to facts or circumstances. We also utilize an actuaryrr to calculate reserves required for estimated incurred but not reported claims as well as to estimate the effect of adverse development of claims over time. At December 31, 2021 and 2020, our reserve for product liabia lity was $35.4 million and $35.3 million, respectively. If the estimated loss reserves as of December 31, 2021 developed adversely by 10%, the impact on earnings would be approximately $2.9 million. estimate such loss. There is inherent uncertainty as to the eventual t Pensions We have significant pension benefit costs that are developed from actuarial valuations. The valuations reflect key assumptim ons regarding, among other things, discount rates, expected returnt on plan assets, retirement ages, and years of service. Consideration is given to current market conditions, including changes in interest rates in making these assumptim ons. Our assumptim on for the expected return on plan assets was 6.25 and 6.75 percent in 2021 and 2020, respectively. The discount rate used to determine net periodic pension costs decreased to 2.47 percent in 2021 from 3.18 percent in 2020. For 2022, our expected return on plan assets is 3.00 percent and our discount rate is 2.72 percent. of equity and bond indices and the actual historical returns on plan assets, we evaluate our pension plan’s current and target asset allocation, the In developing our expected returnt expected long-term rates of returnt of our pension plan. Our plan’s target allocation to bonds managers is between 60 to 95 percent with the remainder allocated primarily to equities, private equity managers and cash. Our actual asset allocation as of December 31, 2021, was one percent to equity managers, 75 percent to bond managers, one percent to private equity managers, and the remainder allocated to cash. We regularly review our actual asset allocation and periodically rebalance our investments to our targeted allocation when considered are 9.3 percent and appropriate. Our pension plan’s historical 8.2 percent, respectively. We believe that with our target allocation and the expected long-term returns of equity and bond our 3.00 percent expected returnt indices as well as our actual historical returns, ten-year and 25-year compounded annualized returns on plan assets for 2022 is reasonable. t t t The discount rate assumptim ons used to determine future pension obligations at December 31, 2021 and 2020 were based on plan sponsors to value the the Aon AA Only Above Median yield curve, which was designed by Aon to provide a means forff liabilities of their postretirement benefit plans. The AA Only Above Median yield curve represents a series of annual discount rates from bonds with AA minimum average rating as rated by Moody’s Investor Service, Standard & Poor’s and Fitch Ratings. We will continue to evaluate our actuarial assumptim ons at least annually, and we will adjud st the assumptions as necessary. Lowering the expected returnt on plan assets by 25 basis points would decrease our net pension income for 2021 by approximately $1.8 million. Lowering the discount rate by 25 basis points would increase our 2021 net pension income by approximately $0.7 million. Pension Planl Termination In 2021, our Board of Directors approved the termination of our defined benefit pension plan (the Plan) with a termination date of December 31, 2021. The Plan has filed for a determination letter from the IRS regarding the qualification of the plan termination. The Plan represents over 95 percent of our pension plan liability. In 2022, we expect to annuitize the remaining pension liability. The Plan settlement, which we expect to complete in the fourth quarter of 2022, will accelerate the recognition of approximately $445 million, or $1.73 of EPS, of non-cash, pre-tax pension expenses. In addition, to protect the Plan’s funded status, the Plan transferred a significant portion of its assets to lower risk investments in 2021. The impact of this transition will result in a lower expected rate of return on pension investments and accordingly, higher pension expenses in 2022, compared to previous years. As part of our strategy to de-risk our defined benefit pension plan, the qualified defined benefit pension plan purchased a group annuity contract whereby an unrelated insurance company assumed $23 million obligation to pay and administer future annuity payments for certain retirees and beneficiaries in 2020. 24 We recognized pension income of $12.0 million and $5.1 million in 2021 and 2020, respectively. To provide improved transparency into the operating results of our business in 2022 we will provide a non-GAAP measure (adjusted earnings per share) that excludes the impact of our estimated pension settlement charge and non-operating pension income and expenses. A reconciliation from GAAP measures to non-GAAP measures is provided in the financial inforff mation included in this filing.

Includes pre-tax pension income of $10.5 million and $2.6 million, within the North America segment and Corporate expenses, respectively. 25 Outlook As we begin 2022, we expect our consolidated sales to increase between 16 to 18 percent compared to 2021. Our higher expected sales are driven by pricing actions in North America and increased boiler and water treatment volumes within that region. We expect to achieve full-year earnings of between $1.56 and $1.76 per share and an adjusted EPS in the range of $3.35 and $3.55 per share. Our 2022 guidance excludes the potential impacts from future acquisitions and assumes the recent surge of the Omicron variant subsides during the first quarter of 2022 and does not have a significant impact on our productivity or significantly impact the end markets that we serve. 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 2021 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. t Risk Management Our Enterprise Risk Management (ERM) process 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 Enterpriseii Riskii 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, disruptive technologies and cyber threats among others, and assigns an executive to address each majora 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 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. t 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 of Notes to Consolidated Financial Statements. We enter into foreign currency forward contracts to minimize the effect of fluctuating foreign currencies. At December 31, 2021, we had net foreign currency contracts outstanding with notional values of $186.3 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 $18.6 million. However, gains and losses from our forward contracts will be offset by gains and losses in the underlying transactions being hedged. 26 Forward-Looking Statements ff ff rd-looking statements” within the meaning of the Private Securities This filing contains statements that we believe are “forwa Litigation Reform Act of 1995.

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, 2021 and 2020, 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, 2021, and the related notes and financial statement scheduled 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, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, 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, 2021, 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 11, 2022 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 include 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. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the account or disclosure to which it relates. 28 Description of the Matter Product Warrantytt Liabiliii tyii Valuation At December 31, 2021, the Company’s product warranty liability was $184.4 million. As discussed in Note 1 of the consolidated financial statements, the Company records a liability for the expected cost of ated claims at the time of sale. The product warranty liability is estimated based upon warranty-rel t warrantyt loss experience using actual historical failure rates and estimated cost of product replacement. Products generally carry warranties from one to ten years. The Company performs separate warranty calculations based on the product type and the warranty term and aggregates them. Auditing the product warranty liability was complex due to the judgmental naturet of the warranty loss experience assumptim ons, 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 historical product failure rates, or that a product quality issue has not yet been identified as of the financial statement date. 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 assumptim ons and the data inputs to the calculation. To test the Company’s calculation of the product warranty liability, our audit procedures included, among others, evaluating the methodology used, and testing the significant assumptim ons discussed above and the underlying data used by the Company in its analysis. We tested the validity and categorization of claims by product type and warrantyt period within the calculation and tested the completeness of the claims data against the Company’s claim log. We recalculated the historical failure rates using actual claims 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 subsequent claims data to identify changes in failure trends and assessed the historical accuracy of the prior year liability. Further, we inquired of operational and quality control personnel regarding quality issues and trends. /s/ Ernst & Young LLP We have served as A. O. Smith Corporation’s auditor since 1917.

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. amounts of cash, cash equivalents, marketable securities, receivables, Fair value of financial instruments. The carrying s approximated fair value as of December 31, 2021 and 2020, due to the short maturities floating rate debt and trade payablea or frequent rate resets of these instrume nts. The fair value of term notes with insurance companies was approximately $128.4 rr million as of December 31, 2021 compared with the carryrr ing amount of $145.9 million for the same date. The fair value of term notes with insurance companies was approximately $123.3 million as of December 31, 2020 compared with the carrying amount of $113.2 million. rr rr 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 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 2021, 2020, or 2019. 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, 2021, 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. 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 majori ty of the Company’s domestic inventories, which comprised 64 percent and 67 percent of the Company’s total inventory at December 31, 2021 and 2020, respectively. Inventories of foreign subsidiaries, the remaining es were determined using the first-in, first-out (FIFO) method. domestic inventories and suppli u a 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. Separablea 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 five 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 carryr ing amount . If the sum of the expected undiscounted cash flows is less than the carrying value of the related asset may not be recoverablea rence between the fair value and carrying value of the asset or group of or group of assets, a loss is recognized for the diffeff assets. Such analyses involves significant judgment. Product warranties. The Company’s products carry warranties that generally range from one to ten 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 at the time of sale and is estimated based on the warranty period, product type and loss experience using actual historical failure 34 1. Organization and Significant Accounting Policies (continued) 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 forff any such warranty issues as they become known and estimable. The allocation of the warranty liabia lity between current and long-term is based on expected warranty claims to be paid in the next year as determined by historical product failure rates. The increase in our reserve for product warranties in 2021 compared to the prior year was primarily due to increased steel prices and the acquisition of Giant Factories, Inc. (Giant). Refer to Note 3, "Acquisitions", for additional information regarding the acquisition of Giant.

The Company utilizes certain derivative instruments to enhance its abila 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 14, “Derivative Instruments” of the notes to consolidated financial statements for disclosure of the Company’s derivative instruments and hedging activities. Fair Value Measurements. Accounting Standards Codification (ASC) 820 Fair ValVV ue Measurements, among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each majora asset r and liability category measured at fair value on either a recurring basis or nonrecurring basis. ASC 820 clarifies that faiff value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liabia lity in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptim ons that market participants would use in pricing an asset or liabia lity. As a basis for considering r value hierarchy, which prioritizes the inputs used in measuring fair such assumptim ons, ASC 820 establia 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. shes a three-tier faiff 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): Fair Value Measurement Usingg Quoted prices in active markets forff identical assets (Level 1) Significant other observable inputs (Level 2) December 31, 2021 December 31, 2020 $ 188.1 $ (0.7) 116.5 (4.3) 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.

Costs of estimated future ff 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, the Company recognized $5.6 million, $4.2 million, and $2.3 million of discrete income tax benefits on settled stock based compensation awards during 2021, 2020, and 2019 respectively. Income taxes. The provision for income taxes is computed using the asset and liability method, in accordance with ASC 740 tax consequences of Income Taxes, under which deferred tax assets and liabilities are recognized for the expected future temporary differences between the financial reporting and tax bases of assets and liabilities and for operating losses and tax rds. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to credit carryfrr orff war taxable income in effect for the years in which those tax assets are expected to be realized or settled and are classifiedff 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. ff 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 benefitsff such positions are then measured based on the largest benefit that has a greater recognized in the financial statements fromff 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 since its Class A Common Stock and Common Stock have equal dividend rights.

The contracts are executed with majora counterparties to perform. ons with no credit loss anticipated forff financial instituti t Cash FlowFF Hedgesg 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 flowff hedge (i.e., hedging the exposure to variability in expected future cash flows that is attributablea 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 reclassifieff d into earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affecff ts earnings. Foreigni Currency Forward Contractstt The Company is exposed to forei ff gn currency exchange risk as a result of transactions in currencies other than the functional gn currency forward purchase and sale contracts to manage the currency of certain subsidiaries.

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 $(0.5) million and $(3.1) million of after-tax losses associated with hedges of a net investment in non-U.S. subsidiaries in currency translation adjustment in other comprehensive income in 2021 and 2020, respectively.

Management Report on Internal Control Over Financial Reporting shing and maintaining adequate internal control over financial reporting (as defined Our management is responsible for establia 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 forff 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. Consistent with guidance issued by the Securities and Exchange Commission that an assessment of a recently acquired business may be omitted from management’s report on internal control over financial reporting in the year of acquisition, management excluded an assessment of the effectiveness of the Company’s internal control over financial reporting related to Giant Factories, Inc. The acquisition constitutet d 7.1 percent and 10.9 percent of total assets and net assets, respectively, as of December 31, 2021 and 0.6 percent and 0.5 percent of net sales and net earnings, respectively. Based on this evaluation, our management has concluded that, as of December 31, 2021, our internal control over financial reporting was effecff tive. 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, 2021 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, 2021 that have materially affecff ted, or are reasonably likely to materially affect, our internal control over financial reporting.

Smith Corporation’s internal control over financial reporting as of December 31, 2021, based on criteria establia shed 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, 2021, based on the COSO criteria. As indicated in the accompanying Management Report on Internal Control Over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Giant Factories, Inc., which are included in the 2021 consolidated financial statements of the Company and constituted 7.1 percent and 10.9 percent of total assets and net assets, respectively, as of December 31, 2021 and 0.6 percent and 0.5 percent of net sales and net earnings, respectively, for the year then ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of Giant Factories, Inc. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of A. O. Smith Corporation as of December 31, 2021 and 2020, and the related consolidated statements of earnings, comprehensive earnings, stockholders’ equity, and cash flows for each of the three years listed in the index at Item in the period ended December 31, 2021, and the related notes and financial statement scheduled 15(a) and our report dated February 11, 2022 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 applicablea 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.
