Plain-text annual report

2020 ANNUAL REPORT LETTER TO SHAREHOLDERS MARCH 2021 Dear Shareholders: Despite 2020 being the most challenging year in recent history, A. O. Smith found a way to manage through the crisis because of the resiliency of our employees, the commitment of our partners and the support of our shareholders. Ending the year in a position of strength required us to think differently, respond quickly and take action amidst a sea of unknowns. Deemed an essential business at the outset of the COVID-19 pandemic, our employees responded to the critical needs of our customers and communities for clean, hot water to help ﬁght the virus. As an organization, taking care of our employees is our highest priority, so we quickly implemented steps to keep people safe in our manufacturing operations and administrative ofﬁces. This allowed our employees to continue to build these necessary products throughout the pandemic. Kevin Wheeler, Chairman, President and Chief Executive Officer I cannot tell you how proud I am of the A. O. Smith employees around the world who made it their personal mission to ensure the health and safety of each other so we could remain operational, our maintain production commitments. Our employees demonstrated their tenacity by continuing to do their jobs, learning and adopting new technologies and adjusting to new ways of working. and meet levels A. O. Smith stepped up to partner with hospitals, schools, nonproﬁts and other businesses to leverage our expertise and lifesaving products. We donated thousands of air puriﬁcation systems to more than 100 hospitals in China, sent personal protective equipment (PPE) to a school in South Carolina, and quickly built and installed water heaters for mobile hospitals in Georgia. These are just a few examples of how we responded to help keep our friends, neighbors and communities safe and healthy. The State of Georgia deployed four, 24-bed mobile hospitals in Albany and Macon, with hot water in every room. The A. O. Smith China team built, delivered, installed and donated water heaters to dozens of hospitals in China to help combat the virus. and products, while In spite of the complexities of navigating this global pandemic, our businesses performed well overall, bolstered by replacement demand for residential water heaters in North America. As a company, A. O. Smith was able to achieve $2.9 billion in sales and $345 million in net earnings in 2020, or $2.12 per share. Our strong balance sheet and liquidity position has enabled A. O. Smith to continue to invest in innovative technologies continuously improving our processes to enhance our productivity. Cash provided by operations last year was approximately $562 million and our debt-to-capital ratio was 5.8% at the end of 2020. We have cash balances totaling approximately $689 million, and our net cash position was approximately $576 million at the end of the year. In the ﬁrst quarter of 2020, we repurchased 1.3 million shares of common stock for approximately $57 million before suspending the program at the outset of the pandemic, and every quarter, we delivered a healthy dividend to shareholders. At the end of the year, we completed our 2020 Corporate Responsibility & Sustainability Report, just the second in our history, reﬂecting the company’s commitment to ongoing environmental, social and governance activities and performance. We’re conﬁdent of our future and to prove it, we put our stake in the ground by announcing our ﬁrst greenhouse gas emissions goal of 10% reduction by 2025. When school resumed in McBee, S.C., more than 2,700 disposable face masks were available for students in need. Our team works hard to earn your trust and conﬁdence every day. We are grateful for your support of A. O. Smith and the opportunity to be stewards of your investment. We look forward to the coming year with conﬁdence and a solid foundation to enable us to achieve our goals, deliver value to our shareholders and fulﬁll our promise to customers and employees throughout the world. Sincerely, Sincerely Kevin J Wheeler Kevin J. Wheeler Chairman, President & Chief Executive Ofﬁcer HOME BECOMES A HAVEN AND MUCH MORE A. O Smith products are truly on the front lines of the ﬁght against COVID19 and without clean, hot water, more lives would be at risk. Helping people feel safe and comfortable at home remains one of our top priorities and through the efforts of many, we will help win the battle against the virus. Staying home took on new meaning this past year. We’re doing our part to make the experience as safe and comfortable as possible. It is often said that home is where the heart is, but never before have our homes become the place where literally everything happens. From virtual learning and remote working to working out and connecting with friends, we’re doing it all within the conﬁnes of our four walls during these pandemic times. With large numbers of people staying home and using more water with greater frequency, A. O. Smith employees stepped up and faced each challenge the pandemic put in front of us without hesitation. We did this knowing it is our job to take care of each other and deliver on our promise to supply high-quality water heating and treatment products to homes across the globe. This commitment didn’t happen just because we were deemed essential workers in this ﬁght against the virus; it is part of our 146-year commitment to doing the right thing… for our employees and our customers. It is the foundation upon which A. O. Smith was built. HELPING BUSINESSES STAY OPEN Across the world, small businesses, government organizations, large corporations and healthcare systems experienced the critical need for hot water for sanitization, clean water to drink and air puriﬁcation systems to help reduce the risk of infection for customers, employees and patients. Working closely with our suppliers and distributors to ensure our products were delivered on time so that businesses could stay open safely required our team to pivot quickly to minimize any disruption in our supply chain. By anticipating and diligently responding to the evolving needs of those we serve, A. O. Smith continues to play a direct role in keeping businesses open and operating safely. Our A. O. Smith teams went above and beyond in other signiﬁcant ways during a time when normal operations were anything but normal. In China, the company donated and installed thousands of air puriﬁcation units to hospitals across that country. In the United States, donations of PPE, such as disposable masks and safety glasses, were made to schools and hospitals. Answering the call for help took many forms, including building, delivering and installing commercial boilers and water heaters in just a matter of days for makeshift hospitals and temporary housing units for COVID-19 patients. The world will continue to change and so will A. O. Smith – ﬁnding innovative ways to manufacture our products, developing new capabilities and helping our customers thrive during unprecedented times and beyond is in our DNA. 2020 NOTABLE HONORS In following our Statement of Values, we earned several notable honors in 2020.

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 and electric water heaters, boilers, tanks and water treatment products. Both segments primarily manufacture and market in their respective regions of the world. NORTH AMERICA 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. Typical applications for our water heaters include residences, restaurants, hotels and motels, office buildings, laundries, car washes, schools and small businesses. Boilers. Our residential and commercial boilers range in size from 45,000 British Thermal Units (BTUs) to 6.0 million BTUs. Our boilers are primarily used in space heating applications for residences, hospitals, schools, hotels and other large commercial buildings. 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 and Water- Right, Inc. (Water-Right) in 2019. 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 1,200 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 40 percent of Lochinvar branded sales consist of residential and commercial water heaters while the remaining 60 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 Aquasana branded products primarily directly to consumers through e-commerce as well as on-line retailers including Amazon and through other retail chains. Our water softener branded products and problem well water solutions, which include Hague, WaterBoss, Water-Right, WaterCare, and Evolve, are sold through water quality dealers. Our water softener products are also sold through home center retail chains. Our A. O. Smith branded water treatment products are sold through Lowe’s, Amazon, and our wholesale distribution channels. Our energy-efficient product offerings continue to be a sales driver for our business. Our commercial water heaters and our condensing boilers continue to be an option for commercial customers looking for high-efficiency water and space heating with a short payback period through energy savings. We offer residential heat 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. We sell our products in highly competitive markets. We compete in each of our targeted market segments based on product design, reliability, quality of products and services, advanced technologies, energy efficiency, maintenance costs and price. 3 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 and Ecowater as well as numerous regional assemblers. REST OF WORLD 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 to the residential market in China in dollar terms. We manufacture and market water treatment products, primarily residential reverse osmosis products. We also manufacture and market air purification products as well as design and market range hoods and cooktops in China. We sell our products in over 13,000 points of sale in China, approximately 6,400 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 13 percent of total Rest of World sales in 2020. RAW MATERIALS Raw materials for our manufacturing operations, primarily consisting of steel, are generally available in adequate quantities, however the current COVID-19 pandemic has periodically stressed the availability of certain raw materials. A portion of our customers are contractually obligated to accept price changes based on fluctuations in steel prices. There has been volatility in steel costs over the last several years, including an increase in steel costs in the second half of 2020. RESEARCH AND DEVELOPMENT To improve our competitiveness by generating new products and processes, we conduct research and development at our Corporate Technology Center in Milwaukee, Wisconsin, our Global Engineering Center in Nanjing, China, and our operating locations. Our total expenditures for research and development in 2020, 2019 and 2018 were $80.7 million, $87.9 million and $94.0 million, respectively. PATENTS AND TRADEMARKS We own and use in our businesses various trademarks, trade names, patents, trade secrets and licenses. We do not believe that our business as a whole is materially dependent upon any such trademark, trade name, patent, trade secret or license. However, our trade name is important with respect to our products, particularly in China, India and the U.S. HUMAN CAPITAL We employed approximately 13,900 employees as of December 31, 2020, primarily non-union. We have a set of values for conducting our business and interacting with our employees as outlined in the A. O. Smith Corporation Guiding Principles. These principles help to shape how we hire, train and treat our employees. We believe that the critical elements of the effort to retain and develop talent are employee engagement, talent development, a focus on employee safety, and market competitive compensation. 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 provide all employees with a wide range of professional development experiences, both formal and informal. Some of the formal development programs that employees have access to include early-career leadership development programs, continuous improvement skill-building programs, and tuition reimbursement for degree programs or trade schools. 4 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 Safety Award, which acknowledges an A. O. Smith facility that demonstrates the most improvement over one year in the area of workplace safety. Specific to the COVID-19 pandemic, we have undertaken numerous and meaningful steps to protect our employees, suppliers, and customers. See Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations," of this Annual Report on Form 10-K for additional information. We provide what we believe is a robust total compensation program designed to be market-competitive and internally equitable to attract, retain, motivate and reward a high-performance workforce. Regular internal and external analysis is performed to ensure this market alignment. In addition to salaries, these programs, which vary by country, can include annual bonuses, stock-based compensation awards, retirement plans with employee matching opportunities, and other benefits. 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, labeling, storage, distribution, advertising and sale of our products, are subject to various federal, state, local and foreign laws and regulations. In the U.S., many of our products are regulated by the Department of Energy, the Consumer Product Safety Commission, and the Federal Trade Commission. State and local governments, through laws, regulations, and building codes, also regulate our water heating and water treatment products. Whether at the federal, state, or local level, these laws are intended to improve energy efficiency and product safety, and protect public health and the environment. Similar laws and regulations have been adopted by government authorities in other countries in which we manufacture, distribute, and sell our products. In addition, our operations are subject to federal, state and local environmental laws. We are subject to regulations of the U.S. Environmental Protection Agency and the Occupational Health and Safety Administration and their counterpart state agencies. Compliance with government regulations and environmental laws has not had and is not expected to have a material effect upon the capital expenditures, earnings, or competitive position of our company.

These risks could have an impact on our business, financial condition, operating results and cash flows. The risks set forth below are not an exhaustive list of potential risks but reflect those that we believe to be material. You should carefully consider the risk factors set forth below and all other information contained in this Annual Report on Form 10-K, including the documents incorporated by reference, before making an investment decision regarding our common stock. If any of the events contemplated by the following risks were to actually occur, then our business, financial condition, or results of operations could be materially adversely affected. As a result, the trading price of our common stock could decline, and you may lose all or part of your investment. Economic and Industry Risks ■ The global coronavirus (COVID-19) pandemic, or other global public health pandemics, could have a material adverse effect 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, workforce or other manufacturing and distribution capability. 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 difficulties, or mandated shutdowns by governmental authorities, may adversely impact our operations. Significant reductions in demand, particularly for our commercial products, or significant volatility in demand and a global economic recession that could further 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 commercial sector, such as the restaurant and hospitality industries in which we have customers, will experience long-term shifts in consumer behavior which could negatively impact demand or capacity and may not return to pre- pandemic levels. • 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 capital, credit, and financial markets that could limit our ability to obtain external financing to fund our operations and capital expenditures. 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 is highly uncertain and will depend on future developments. Such developments may include the geographic spread and duration 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. ■ The effects of a global economic downturn could have a material adverse effect on our business Global economic growth remains volatile and could stall or reverse course. A continuation or deepening of the global economic downturn 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. In addition, a deterioration in current economic conditions due to many factors or fears including public health crises 6 or political instability, 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 24 percent of our net sales in 2020 were attributable to China, adverse economic conditions or changes in consumer behavior in China could impact our business Our sales in China decreased in 2020 compared to 2019. We believe the decrease was due to business closures and restrictions associated with the COVID-19 pandemic, weaker end-market demand, a higher sales mix of mid-price products versus premium price products and further reductions to previously elevated channel inventory levels. We derive a substantial portion of our sales in China from premium-tier products. Changes in consumer preferences and purchasing behaviors including preferences for e-commerce, 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. ■ Because we participate in markets that are highly competitive, our revenues and earnings could decline as we respond to competition We sell all of our products in highly competitive and evolving markets. We compete in each of our targeted markets based on product design, reliability, quality of products and services, advanced technologies, product performance, maintenance costs and price. Some of our competitors may have greater financial, marketing, manufacturing, research and development and distribution resources than we have; others may invest little in technology or product development but compete on price and the rapid replication of features, benefits, and technologies, and some are increasingly expanding beyond their existing manufacturing or geographic footprints. 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 ten percent of the residential market segment in 2020, 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. ■ Our business could be adversely impacted by changes in consumer purchasing behavior, consumer preferences 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 new 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, and retain necessary intellectual property rights is essential to our continued success, but cannot reasonably be assured. It is possible that we will not be able to develop new technologies, products or distribution channels to align with consumer purchasing behavior and consumer preferences, which could materially and adversely affect our financial condition, results of operations and cash flows. ■ The occurrence or threat of extraordinary events, including natural disasters, political disruptions, terrorist attacks, public health issues, and acts of war, could significantly disrupt production, or impact consumer spending As a global company with a large international footprint, we are subject to increased risk of damage or disruption to us and our employees, facilities, suppliers, distributors, or customers. Extraordinary events, including natural disasters, 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. One of our manufacturing plants is 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 disruptions or other extraordinary events outside of our control that impact our operations or the operations of our suppliers and key distributors could affect our business negatively, harming operating results. In addition, 7 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. Business, Operational, and Strategic Risks ■ We sell our products and operate outside the U.S., and to a lesser extent, rely on imports and exports, which may present additional risks to our business Approximately 33 percent of our net sales in 2020 were attributable 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 7,500 of our 13,900 employees as of December 31, 2020 were located in China. At December 31, 2020, approximately $524 million of cash and marketable securities were held by our foreign subsidiaries, substantially all of which were located in China. International operations generally are subject to various risks, including: political, religious, and economic instability; local labor market conditions; new or increased tariffs or other trade restrictions, or changes to trade agreements; the impact of foreign government regulations, actions or policies; the effects of income taxes; governmental expropriation; the imposition or increases in withholding and other taxes on remittances and other payments by foreign subsidiaries; labor relations problems; the imposition of environmental or employment laws, or other restrictions or actions by foreign governments; and differences in business practices. Unfavorable changes in the political, regulatory, or trade climate, diplomatic relations, or government policies, particularly in relation to countries where we have a presence, including Canada, China, India and Mexico, could have a material adverse effect on our financial condition, results of operations and cash flows or our ability to repatriate funds to the U.S. ■ A material loss, cancellation, reduction, or delay in purchases by one or more of our largest customers could harm our business Net sales to our five largest customers represented approximately 43 percent of our sales in 2020. 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. Other customers may experience financial instability. Further, a customer may be acquired by a customer of a competitor which could result in our loss of that customer. The loss of one or more of our largest customers, any material reduction or delay in sales to these customers, or our inability to successfully develop relationships with additional customers could have a material adverse effect on our financial position, results of operations and cash flows. ■ A portion of our business could be adversely affected by a decline in North American new residential construction further decline in commercial construction or a decline in replacement 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 declined in 2020 after growing modestly in 2019. We believe that the significant majority of the markets we serve are for replacement of existing products, and residential water heater replacement volume was strong in 2020. Changes in the replacement volume and in the construction market in North America could negatively affect us. ■ Our operations could be adversely impacted by material and component price volatility and availability, as well as supplier concentration The market prices for certain materials and components we purchase, primarily steel, have been volatile. In addition, some components are subject to long lead times. We engage in ongoing communications with our suppliers to identify and mitigate risk of potential disruptions and to manage inventory levels. Significant increases in the cost of any of the key materials and components we purchase 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. Historically, there has been a lag in our ability to recover increased material costs from customers, and that lag could negatively impact our profitability. Limited component availability and long lead times could make it difficult for us to meet customer demand. 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. 8 ■ An inability to adequately maintain our information systems and their security, as well as to protect data and other confidential information, could adversely affect our business and reputation In the ordinary course of business, we utilize information systems for day-to-day operations, to collect and store sensitive data and information, including our proprietary and regulated business information and personally identifiable information of our customers, suppliers and business partners, as well as personally identifiable information about our employees. Our information systems, like those of other companies, are susceptible to outages due to system failures, cybersecurity threats, failures on the part of third-party information system providers, natural disasters, power loss, telecommunications failures, viruses, fraud, theft, malicious actors or breaches of security. 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. However, any operations failure or breach of security which are occurring with increasing frequency from increasingly sophisticated cyber threats 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. ■ Our international operations are subject to risks related to foreign currencies We have a significant presence outside of the U.S., primarily in China and Canada and to a lesser extent Europe, Mexico, and India, and therefore, hold assets, including $385 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 instability 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 majority of our foreign currency transaction risk results from sales of our products in Canada 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 defects Product defects can occur through our own product development, design and manufacturing processes or through our reliance on third parties for component design and manufacturing activities. We may incur various expenses related to product defects, including product warranty costs, product liability and recall or retrofit costs. While we maintain a reserve for product warranty costs based on certain estimates and our knowledge of current events and actions, our actual warranty costs may exceed our reserve, resulting in current period expenses and a need to increase our reserves for warranty charges. In addition, product defects and recalls may diminish the reputation of our brand. Further, our inability to cure a product defect could result in the failure of a product line or the temporary or permanent withdrawal from a product or market. Any of these events may have a material adverse impact on our financial condition, results of operations and cash flows. ■ Potential acquisitions could use a significant portion of our capital and we may not successfully integrate future acquisitions or operate them profitably or achieve strategic objectives We will continue to evaluate potential acquisitions, and we could use a significant portion of our available capital to fund future acquisitions. If we complete any future acquisitions, we may not be able to successfully integrate the 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 local regulations and market customs 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 effect on our financial condition, results of operations and cash flows. Legal, Regulatory, and Governance Risks ■ Changes in regulations or standards could adversely affect our business Our products are subject to a wide variety of statutory, regulatory and industry standards and requirements related to, among other items, energy and water efficiency, environmental emissions, labeling and safety. While we believe our products are 9 currently efficient, safe and environment-friendly, federal, foreign, state and local governments are adopting 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 delivery of natural gas in new construction. A significant change to regulatory requirements that promote a transition to alternative 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. ■ We are subject to U.S. and global laws and regulations covering our domestic and international operations that could adversely affect our business and results of operations Due to our global operations, we are subject to many laws governing international relations, including those that prohibit improper payments to government officials and restrict where we can do business, what information or products we can supply to certain countries and what information we can provide to a non-U.S. government, including but not limited to the Foreign Corrupt Practices Act and the U.S. Export Administration Act. Violations of these laws may result in criminal penalties or sanctions that could have a material adverse effect on our financial condition, results of operations and cash flows. ■ Our results of operations may be negatively impacted by product liability lawsuits and claims Our products expose us to potential product liability risks that are inherent in the design, manufacture, sale and use of our products. While we currently maintain what we believe to be suitable product liability insurance, we cannot be certain that we will be able to maintain this insurance on acceptable terms, that this insurance will provide adequate protection against potential liabilities or that our insurance providers will be able to ultimately pay all insured losses. In addition, we self-insure a portion of product liability claims. A series of successful claims against us could materially and adversely affect our reputation and our financial condition, results of operations and cash flows. ■ We have significant goodwill and indefinite-lived intangible assets and an impairment of our goodwill or indefinite-lived intangible assets could cause a decline in our net worth Our total assets include significant goodwill and indefinite-lived intangible assets. Our goodwill results from our acquisitions, representing the excess of the purchase prices we paid over the fair value of the net tangible and intangible assets we acquired. We assess whether there have been impairments in the value of our goodwill or indefinite-lived intangible assets during the fourth quarter of each calendar year or sooner if triggering events warrant. If future operating performance at our businesses does not meet expectations, we may be required to reflect non-cash charges to operating results for goodwill or indefinite-lived intangible asset impairments. The recognition of an impairment of a significant portion of goodwill or indefinite-lived intangible assets would negatively affect our results of operations and total capitalization, the effect of which could be material. A significant reduction in our stockholders’ equity due to an impairment of goodwill or indefinite-lived intangible assets may affect our ability to maintain the debt-to-capital ratio required under our existing debt arrangements. We have identified the valuation of goodwill and indefinite-lived intangible assets as a critical accounting policy. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies— Goodwill and Indefinite-lived Intangible Assets” included in Item 7 of this Annual Report on Form 10-K. ■ Our pension plans may require future pension contributions which could limit our flexibility in managing our company The projected benefit obligation liability of our defined benefit pension plans of $870 million exceeded the fair value of the plan assets of $859 million by approximately $11 million at December 31, 2020. U.S. employees hired after January 1, 2010 have not participated in our defined benefit plan, and benefit accruals for the majority of current salaried and hourly employees ended on December 31, 2014. We forecast that we will not be required to make a contribution to the plan in 2021, 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 assumptions inherent in our actuarially calculated pension plan obligation and pension plan expense are the discount rate and the expected rate of return on plan assets. If interest rates and actual rates of return 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. ■ Certain members of the founding family of our company and trusts for their benefit have the ability to influence all matters requiring stockholder approval We have two classes of common equity: our Common Stock and our Class A Common Stock. The holders of Common Stock currently are entitled, as a class, to elect only one-third of our board of directors. The holders of Class A Common Stock are entitled, as a class, to elect the remaining directors. Certain members of the founding family of our company and trusts for 10 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, 2020, through the voting trust, these members of the Smith Family own approximately 63.8 percent of the total voting power of our outstanding shares of Class A Common Stock and Common Stock, taken together as a single class, and approximately 96.6 percent of the voting power of the outstanding shares of our Class A Common Stock, as a separate class. Due to the differences in the voting rights between shares of our Common Stock (one-tenth of one vote per share) and shares of our Class A Common Stock (one vote per share), the Smith Family voting trust is in a position to control to a large extent the outcome of matters requiring a stockholder vote, including the adoption of amendments to our certificate of incorporation or bylaws or approval of transactions involving a change of control. This ownership position may increase if other members of the Smith Family enter into the voting trust agreement, and the voting power relating to this ownership position may increase if shares of our Class A Common Stock held by stockholders who are not parties to the voting trust agreement are converted into shares of our Common Stock. The voting trust agreement provides that, in the event one of the parties to the voting trust agreement wants to withdraw from the trust or transfer any of its shares of our Class A Common Stock, such shares of our Class A Common Stock are automatically exchanged for shares of our Common Stock held by the trust to the extent available in the trust. In addition, the trust will have the right to purchase the shares of our Class A Common Stock and our Common Stock proposed to be withdrawn or transferred from the trust. As a result, the Smith Family members that are parties to the voting trust agreement have the ability to maintain their collective voting rights in our company even if certain members of the Smith Family decide to transfer their shares. ITEM 1B – UNRESOLVED STAFF COMMENTS None. ITEM 2 – PROPERTIES Properties utilized by us at December 31, 2020 were as follows: North America In this segment, we have 16 manufacturing plants located in eight states and two non-U.S. countries, of which 14 are owned directly by us or our subsidiaries and two are leased from outside parties. The terms of leases in effect at December 31, 2020 expire between 2021 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, 2020 expire between 2022 and 2025. Corporate and General We consider our plants and other physical properties to be suitable, adequate, and of sufficient productive capacity 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 liability, 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 effect 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. On May 28, 2019, a putative securities class action lawsuit was filed in the U.S. District Court for the Eastern District of Wisconsin against the Company and certain of its current or former officers. Subsequently, on November 22, 2019, a consolidated amended complaint was filed by the lead plaintiff. This action, captioned as City of Birmingham Retirement and Relief System v. A. O. Smith Corporation, et al., asserted securities fraud claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (“Exchange Act”), and sought damages and other relief based upon the allegations in the complaint. On January 24, 2020, A. O. Smith and the other defendants moved to dismiss the consolidated amended complaint 11 for failure to state a claim. On June 24, 2020, the U.S. District Court granted defendants’ motion to dismiss in its entirety. Based on its June 24, 2020 order, on August 3, 2020, the District Court entered final judgement for the defendants and dismissed the lawsuit. A shareholder derivative lawsuit, captioned as Pierce v. A. O. Smith Corporation, et al. and based on similar allegations as the putative class action, was filed on August 20, 2019, also in the U.S. District Court for the Eastern District of Wisconsin. On November 6, 2019, the plaintiff in the derivative action moved to dismiss his lawsuit, and the plaintiff re-filed it in the U.S. District Court for the District of Delaware on November 12, 2019. The derivative action asserted claims under Sections 14(a) and 20(a) of the Exchange Act, as well as for breach of fiduciary duty, unjust enrichment, and waste of corporate assets, and sought damages and other relief based upon the allegations in the complaint. On February 12, 2020, the parties filed a stipulation seeking to stay the derivative lawsuit pending resolution of the City of Birmingham lawsuit. On February 13, 2020, a second shareholder derivative suit, captioned as Jarozewski v. A. O. Smith Corporation, et al., was filed in the U.S. District Court for the District of Delaware, to assert claims under Sections 10(b), 14(a) and 20(a) of the Exchange Act, as well as for breach of fiduciary duty, unjust enrichment, and insider trading, and sought damages and other relief based upon the allegations in the complaint. On April 1, 2020, the U.S. District Court for the District of Delaware, upon a joint stipulation filed by the parties, consolidated both the Pierce and Jarozewski derivative lawsuits and stayed the consolidated actions pending resolution of the City of Birmingham lawsuit. On October 7, 2020, following dismissal of the City of Birmingham lawsuit and upon a joint stipulation filed by the parties, the District Court dismissed the consolidated derivative lawsuits. A. O. Smith and the other defendants paid no settlement consideration to achieve these dismissals.

Our Common Stock is listed on the New York Stock Exchange under the symbol AOS. Our Class A Common Stock is not listed. EQ Shareowner Services, P.O. Box 64874, St. Paul, Minnesota, 55164-0874 serves as the registrar, stock transfer agent and the dividend reinvestment agent for our Common Stock and Class A Common Stock. (b) (c) (d) Holders. As of January 29, 2021, the approximate number of stockholders of record of Common Stock and Class A Common Stock were 568 and 155, respectively. The actual number of stockholders is greater than this number of holders of record, and includes stockholders who are beneficial owners, but whose shares are held in street name by brokers and other nominees. 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 18 of Notes to Consolidated Financial Statements appearing elsewhere herein. Stock Repurchases. In the second quarter of 2019, our Board of Directors approved adding 3,000,000 shares of Common Stock to an 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 capital 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. Due to the uncertainty surrounding the impact of the global COVID-19 pandemic, we suspended our share repurchases on March 18, 2020. In 2020, we repurchased 1,348,391 shares at an average price of $42.02 per share and at a total cost of $56.7 million. As of December 31, 2020, there were 1,613,824 shares remaining on the existing repurchase authorization. On January 27, 2021, the Board of Directors approved adding 7,000,000 shares of common stock to the existing discretionary share repurchase authority. Including the additional shares, we have approximately 8.6 million shares available for repurchase. We currently intend to spend approximately $400 million to repurchase common stock in 2021 through a combination of 10b5-1 plans and open market purchases. (e) Performance Graph.

These charges reduced 2017 earnings per share by $0.47. In September 2016, we declared a 100 percent stock dividend to holders of Common Stock and Class A Common Stock which is not included in cash dividends. Basic and diluted earnings per share are calculated using the weighted average shares outstanding which were restated for all periods presented to reflect the stock dividend. Excludes the current portion of long-term debt. 18 ITEM 7 – MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OVERVIEW Our company is comprised of two reporting segments: North America and Rest of World. Our Rest of World segment is primarily comprised of China, Europe and India. 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 region of the world. In January 2020, an outbreak of a novel coronavirus (COVID-19) surfaced in Wuhan, China. As a result of the outbreak, the Chinese government required businesses to close and restricted certain travel within the country. In cooperation with the government authorities, our operations in China closed for approximately four weeks before resuming production before the end of the first quarter. In March 2020, COVID-19 was declared a global pandemic and we experienced impacts to our business and other markets worldwide. To date, our global manufacturing operations of essential water heating and water treatment products continue without material disruption to our operations. 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. These important steps, which in certain cases reduce efficiency, include continuous communication and training to our employees on living and working safely in a COVID-19 environment, plant accommodations and reconfigurations to maintain social distancing, masks for all employees, implementation of sanitizing stations, temperature taking and regular, proactive deep cleaning and sanitization of our facilities, among others. As we receive guidance from governmental authorities, we adjust our safety measures to meet or exceed those guidelines. The majority of our customers in the U.S. are also deemed essential under Cybersecurity and Infrastructure Security Agency (CISA) guidance and are operating their businesses under varying state and local governmental guidance. Our global supply chain management team continues to monitor and manage our ability to operate effectively during the COVID-19 pandemic. To date, we have not seen any material disruptions to our supply chain, although we have seen an increase in logistics costs and shipment times as a result of pandemic-related capacity reductions. Ongoing communications with our suppliers to identify and mitigate risk of potential disruptions and to manage inventory levels continue. Our U.S. water heater manufacturing lead times, which were extended in the second and third quarters due to self-quarantine absenteeism mandated by our COVID-19 prevention measures, stabilized in the fourth quarter of 2020 as a result of adding manufacturing shifts, hiring temporary workers and shifting some production. While we believe our balance sheet and capital position are strong, proactive management of discretionary spending and cost structure will continue. On May 1, 2020, the members of our Board of Directors voluntarily reduced the cash component of their board compensation by 25 percent and our chairman and chief executive officer (CEO) voluntarily reduced his base salary by 25 percent. Our CEO’s staff, which includes our other named executive officers, also volunteered a 15 percent reduction in base salary. Full compensation of our Board of Directors, our CEO and our CEO’s staff was reinstated on October 1, 2020. We estimate that between 80 to 85 percent of our water heater and boiler units sold in the U.S. relate to replacement business. While we expect that our replacement business in both water heating and boilers will provide a buffer in any economic downturn resulting from COVID-19 in a similar manner to what we have seen historically, the impacts of the pandemic on consumer spending are difficult to predict. In our North America segment, we expect industry residential water heater volumes will be down approximately two percent in 2021 compared with 2020, which is driven by our belief that customers may have added inventory in 2020 due to industry extended lead times. We believe that some de-stocking by our customers will occur in early 2021 as our lead times have improved and continue to improve. We believe that commercial water heater industry volumes will further decline approximately four percent in 2021 as COVID-19 pandemic-impacted businesses delay or defer new construction and discretionary replacement installations. We expect to see a mid-single digit increase to our boiler sales in 2021 compared to 2020 due to industry growth of three to four percent driven by pandemic-related pent up demand as well as our new product introductions. We expect sales of our North America water treatment products to increase by 13 to 14 percent in 2021, compared to 2020, primarily driven by consumer demand for our point of use and point of entry water treatment systems. In our Rest of World segment, we expect China sales in 2021 to increase 14 to 15 percent in local currency compared with 2020 due to increased consumer demand. We assume China currency rates will stay at current levels and which would add approximately $47 million and $3 million to sales and earnings in 2021, respectively. In addition, we project that our mix of products sold in China is shifting to more mid-price range products from our historical mix of higher priced products. We also continue to focus on aligning our cost structure in China through headcount reductions, store closures, cuts in advertising 19 and other cost saving measures. Our 2020 headcount reductions and restructuring actions we took were largely completed as of the end of the third quarter of 2020. Combining all of these factors, we expect our consolidated sales to increase approximately ten percent in 2021. Our guidance excludes the potential impacts from future acquisitions and assumes the conditions of our business environment and that of our suppliers and customers are similar in 2021 to what we are experienced in recent months and does not deteriorate as a result of further restrictions or shutdowns due to the COVID-19 pandemic. Our stated acquisition strategy includes a number of our water-related strategic initiatives. We will seek to continue to grow our core residential and commercial water heating, boiler and water treatment businesses throughout the world. We will also continue to look for opportunities to add to our existing operations in high growth regions demonstrated by our introduction of water treatment products in India and Vietnam and range hoods and cooktops in China. RESULTS OF OPERATIONS Our sales in 2020 were $2,895 million, a decline of 3.3 percent compared to our 2019 sales of $2,993 million. Compared to 2019, our sales decline in 2020 was primarily driven by lower sales in China and lower commercial water heater volumes, and reduced boiler sales in North America. The decreased sales in 2020 compared to the prior year more than offset higher water treatment volumes including incremental sales of $16 million from Water-Right, acquired on April 8, 2019 and higher residential water heater volumes in North America. In addition, our sales in China were favorably impacted by currency translation of approximately $9 million in 2020 compared to 2019, due to the appreciation of the Chinese currency compared to the U.S. dollar. Our sales in 2019 were $2,993 million, a decline of 6.1 percent compared to our 2018 sales of $3,188 million. The decrease in 2019 sales was primarily due to a 23 percent decline in China sales in U.S. dollar terms, which was largely a result of weaker end-market demand in the region, year over year channel inventory shifts, and a higher mix of sales of mid-price products versus premium price products than in the prior year. Excluding the unfavorable impact from currency translation, China sales declined 19 percent in 2019. The sales reduction in China in 2019 compared to 2018, more than offset the benefits of higher sales in North America, which were primarily a result of higher sales of water treatment products, including incremental sales from our Water-Right acquisition, and water heater pricing actions related to steel and freight cost increases. The increase in North America sales in 2019 compared to 2018, was partially offset by lower residential water heater volumes. Our gross profit margin in 2020 of 38.3 percent declined compared to our gross profit margin of 39.5 percent in 2019 primarily due to the lower sales volumes. Our gross profit margin in 2019 of 39.5 percent declined compared to our gross profit margin of 41.0 percent in 2018, primarily due to the lower sales volumes in China and a higher mix of mid-price products, which have lower margins, in that region. Selling, general, and administrative (SG&A) expenses were $660.3 million in 2020 or $55.3 million lower than 2019. SG&A expenses were $715.6 million in 2019 or $38.2 million lower than in 2018. The decrease in SG&A expenses in both 2020 and 2019 was primarily due to lower selling and advertising expenses in China. To align our business to current market conditions, we recognized $7.7 million of pre-tax severance and restructuring expenses in 2020. Charges recognized were comprised of $6.8 million severance costs and $0.9 million of other restructuring expenses. On March 21, 2018, we announced a plan to transfer water heater, boiler and storage tank production from our Renton, Washington plant to our other U.S. plants. The majority of the consolidation of operations occurred in the second quarter of 2018. As a result of the relocation of production, we incurred pre-tax restructuring and impairment expenses of $6.7 million in the first quarter of 2018, primarily related to employee severance, building lease exit costs, and the impairment of assets. These activities are reflected in "severance, restructuring, and impairment expenses" in the accompanying financial statements. We provide non-U.S. Generally Accepted Accounting Principles (GAAP) measures (adjusted earnings, adjusted earnings per share, and adjusted segment earnings) that exclude severance, restructuring, and impairment expenses. Reconciliations to measures on a GAAP basis are provided later in this section. We believe that the measures of adjusted earnings, adjusted EPS, and adjusted segment earnings provide useful information to investors about our performance and allow management and our investors to better understand our performance between periods without regard to items we do not consider to be a component of our core operating performance. Interest expense was $7.3 million in 2020, compared to $11.0 million in 2019 and $8.4 million in 2018. The decrease in interest expense in 2020 was primarily due to lower debt levels and lower interest rates than the prior year. The increase in interest expense in 2019 compared to 2018 was primarily due to higher debt levels utilized to fund the acquisition of Water- Right and share repurchase activity. 20 Other income was $11.0 million in 2020 compared to $18.0 million in 2019 and $21.2 million in 2018. The decrease in other income in 2020 compared to 2019 was primarily due to lower interest income. The decrease in other income in 2019 compared to 2018 was primarily due to lower non-service cost-related pension income and lower interest income. Pension income in 2020 was $5.1 million compared to $6.2 million in 2019 and $8.7 million in 2018. 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 22.3 percent in 2020, compared with 21.6 percent in 2019 and 20.4 percent in 2018. Our effective income tax rate in 2020 and 2019 was higher compared to the prior years primarily due to a change in geographic earnings mix. North America Sales in our North America segment were $2,118 million in 2020 or $34 million higher than sales of $2,084 million in 2019. Compared to 2019, the increased 2020 sales were primarily due to higher volumes of residential water heaters and a 25 percent increase in water treatment product sales, including $16 million of incremental sales from Water-Right. This increase was partially offset by lower U.S. commercial water heater volumes, lower boiler sales and a water heater sales mix composed of more electric models which have a lower selling price. Sales in our North America segment were $2,084 million in 2019 or $39 million higher than sales of $2,045 million in 2018. The increase in sales in 2019 compared to 2018 was primarily due to the incremental Water-Right sales of $44 million, water heater pricing actions related to steel and freight cost increases, and higher sales of water treatment products, which were partially offset by lower residential water heater volumes. North America segment earnings were $503.5 million in 2020 compared to segment earnings of $488.9 million and $464.1 million in 2019 and 2018, respectively. Segment margins were 23.8 percent, 23.5 percent and 22.7 percent in 2020, 2019 and 2018, respectively. Adjusted segment earnings and adjusted segment margin, which exclude severance, restructuring, and impairment expenses, were $506.2 million and 23.9 percent, respectively, in 2020, and $470.8 million and 23.0 percent, respectively, in 2018. The higher adjusted segment earnings and adjusted segment margin in 2020 compared to 2019 segment earnings and segment margin were primarily driven by higher residential water heater volumes, higher water treatment product sales, which included incremental profit from Water-Right, and lower material costs. This was partially offset by lower volumes of commercial water heaters and lower boiler sales. During 2020, segment earnings and margin were adversely impacted by certain costs related to the pandemic. These costs included temporarily moving production from Mexico to the U.S., paying employees during temporary plant shutdowns, proactively deep cleaning facilities, paying benefits during employee furloughs, and other costs, which were approximately $6.6 million in 2020. The higher segment earnings and segment margin in 2019 compared to 2018 adjusted segment earnings and adjusted segment margin were primarily a result of pricing actions, lower steel costs, and higher sales of water treatment products, including incremental volumes from our acquisition, Water-Right. These increases were partially offset by the unfavorable impact from lower residential water heater volumes. We estimate our 2021 North America segment margin will be between 23 and 23.5 percent. Adjusted segment earnings and adjusted segment margin in 2020 exclude $2.7 million of pre-tax severance and restructuring and impairment expenses. These expenses were associated with an initiative to align our business to current market conditions. Adjusted segment earnings and adjusted segment margin in 2018 exclude $6.7 million of pre-tax severance, restructuring and impairment expenses. These expenses were associated with our transfer of our water heater, boiler and storage tank production from our Renton, Washington plant to our other U.S. plants. Rest of World Sales in our Rest of World segment were $800 million in 2020 or $136 million lower than sales of $936 million in 2019. Compared to 2019, our sales in China decreased by 15 percent in U.S. dollar terms and 16 percent in local currency in 2020. In addition, our 2020 sales in China were favorably impacted by currency translation of approximately $9 million compared to 2019, due to the appreciation of the Chinese currency compared to the U.S. dollar. The decrease in Rest of World sales in 2020 was primarily due to COVID-19 pandemic-related lockdowns, weak end-market demand in China, primarily in the first half of 2020, a higher mix of mid-price products which have a lower selling price and year over year channel inventory shifts. Sales in our Rest of World segment in 2019 were $936 million or $238 million lower than sales of $1,174 million in 2018. Lower sales in 2019 compared to 2018 were largely a result of decreased China sales, which declined 23 percent in U.S. dollar terms and 19 percent in local currency terms. The decline in China sales was primarily due to weaker end-market demand, elevated channel inventory levels for the first three quarters of 2019 that returned to a more normal range of two to three months by the end of 2019, and a higher mix of mid-price products versus premium-priced products. In addition, the weaker Chinese currency unfavorably impacted translated sales by approximately $39 million. Sales in India grew approximately 13 percent in 2019 compared to 2018. 21 The Rest of World segment was breakeven in 2020 compared to segment earnings of $40.2 million and $149.3 million in 2019 and 2018, respectively. Segment margins were 4.3 percent and 12.7 percent in 2019 and 2018, respectively. Adjusted segment earnings and segment margin, which exclude severance, restructuring, and impairment expenses, were $5.0 million and one percent, respectively, in 2020. Compared to 2019, the absence of segment earnings in 2020 was driven by the unfavorable impact from lower sales in China and a higher mix of mid-price products, which have lower margins than our historical mix of higher-priced products, and which were partially offset by the benefits from lower selling, advertising, and administrative costs and temporary social insurance exemptions. Currency translation increased segment earnings by approximately $3.6 million in 2020 compared to 2019. The decline in 2019 segment earnings and margin compared to 2018 was primarily due to lower sales in China and a higher mix of mid-price products, which have lower margins, that when combined, more than offset benefits to profits from lower SG&A expenses and material costs in that region. Currency translation reduced segment earnings by approximately $3.0 million in 2019 compared to 2018. We expect full-year segment margin to be between seven percent and eight percent in 2021. Adjusted segment earnings and adjusted segment margin in 2020 exclude $5.0 million of pre-tax severance and restructuring and impairment expenses. These expenses were associated with an initiative to align our business to current market conditions. LIQUIDITY AND CAPITAL RESOURCES Our working capital was $731.7 million at December 31, 2020 compared with $733.9 million and $853.2 million at December 31, 2019 and December 31, 2018, respectively. An increase in cash, cash equivalents and marketable securities was offset by higher accounts payable balances and payroll accruals in 2020 compared to 2019. We repatriated approximately $190 million in foreign cash and marketable securities in 2020 and utilized it to repay floating rate debt. The decline in cash, cash equivalents and marketable securities and sales related decreases in accounts receivable partially offset by lower accounts payable balances led to the majority of the decline in working capital in 2019. Approximately $165 million in foreign cash, cash equivalents and marketable securities was repatriated in 2019 and utilized to repay floating rate debt, pay dividends and repurchase shares. We expect to repatriate approximately $190 million in 2021 and use the proceeds for common stock repurchases. Cash provided by operating activities in 2020 was $562.1 million compared with $456.2 million during 2019 and $448.9 million during 2018. The improvement in operating cash flows in 2020 was primarily due to lower outlays of working capital including higher accounts payable balances in China, which include receipts of cash deposits in advance of sales from certain customers, that more than offset lower earnings. The increase in cash flows in 2019 compared with 2018 was primarily due to lower outlays for working capital which offset lower earnings in 2019. We expect cash provided by operating activities to be $450 million to $475 million in 2021. We continue to monitor developments on an on-going basis and have taken proactive measures to focus on cash, manage working capital, and reduce costs. Our capital expenditures were $56.8 million in 2020, $64.4 million in 2019 and $85.2 million in 2018. Included in 2018 capital expenditures were approximately $13 million related to capacity expansion in China. We project our 2021 capital expenditures to be between $85 and $90 million and expect depreciation and amortization will be approximately $80 million. We have a $500 million multi-currency credit facility with a group of nine banks, which expires in December 2021. The facility has an accordion provision, which allows us to increase it up to $700 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, 2020. We expect to complete a renewal of our credit facility in the first half of 2021. The facility backs up commercial paper and credit line borrowings. As a result of the long-term nature of this facility, our commercial paper and credit line borrowings, as well as drawings under the facility, are classified as long-term debt as of December 31, 2019. At December 31, 2020, we had no borrowings under the facility and an available borrowing capacity of $500 million. We believe the combination of available borrowing capacity and operating cash flows will provide sufficient funds to finance our existing operations for the foreseeable future. Our total debt declined from $284.0 million at December 31, 2019, to $113.2 million at December 31, 2020. Our leverage, as measured by the ratio of total debt to total capitalization, calculated excluding operating lease liabilities, was 5.8 percent at the end of 2020, compared with 14.6 percent at the end of 2019. 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 2020. We forecast that we will not be required to make a contribution to the plan in 2021, and we do not plan to make any voluntary contributions in 2021. For further information on our pension plans, see Note 13 of Notes to Consolidated Financial Statements. 22 In the second quarter of 2019, our Board of Directors approved adding 3,000,000 shares of Common Stock to an existing discretionary share repurchase authority. Under the share repurchase program, our common stock may be purchased through a combination of a Rule 10b5-1 automatic trading plan and discretionary purchases in accordance with applicable 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. Due to the uncertainty surrounding the impact of the global COVID-19 pandemic, we suspended our share repurchases on March 18, 2020. During 2020, we repurchased 1,348,391 shares of our stock at a total cost of $56.7 million. At December 31, 2020, we had 1,613,824 million shares remaining on the board share repurchase authority. On January 27, 2021, the Board of Directors approved adding 7,000,000 shares of common stock to the existing discretionary share repurchase authority. Including the additional shares, we have approximately 8.6 million shares available for repurchase. We currently intend to spend approximately $400 million to repurchase common stock in 2021 through a combination of 10b5-1 plans and open market purchases. We have paid dividends for 81 consecutive years with annual amounts increasing each of the last 29 years. We paid dividends of $0.98 per share in 2020 compared with $0.90 per share in 2019. We increased our dividend by eight percent in the fourth quarter of 2020, and the five-year compound annual growth rate of our dividend payment is approximately 22 percent. Recent Accounting Pronouncements Refer to Recent Accounting Pronouncements 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 assumptions about future events that affect the amounts reported in the financial statements and accompanying notes. Future events and their effects cannot be determined with absolute certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results inevitably will differ from those estimates, and such differences may be material to the financial statements. The most significant accounting estimates inherent in the preparation of our financial statements include estimates associated with the evaluation of the impairment of goodwill and indefinite-lived intangible assets, as well as significant estimates used in the determination of liabilities related to warranty activity, product liability and pensions. Various assumptions and other factors underlie the determination of these significant estimates. The process of determining significant estimates is fact- specific and takes into account factors such as historical experience and trends, and in some cases, actuarial techniques. We monitor these significant factors and adjustments are made as facts and circumstances dictate. Historically, actual results have not significantly deviated from those determined using the estimates described above. Goodwill and Indefinite-lived Intangible Assets In conformity with U.S. Generally Accepted Accounting Principles (GAAP), goodwill and indefinite-lived intangible assets are tested for impairment annually or more frequently if events or changes in circumstances indicate that the assets might be impaired. We perform impairment reviews for our reporting units using a fair-value method based on management’s judgments and assumptions. The fair value represents the estimated amount at which a reporting unit could be bought or sold in a current transaction between willing parties on an arms-length basis. The estimated fair value is then compared with the carrying amount of the reporting unit, including recorded goodwill. We are subject to financial statement risk to the extent that goodwill and indefinite-lived intangible assets become impaired. Any impairment review is, by its nature, highly judgmental as estimates of future sales, earnings and cash flows are utilized to determine fair values. However, we believe that we conduct thorough and competent annual valuations of goodwill and indefinite-lived intangible assets and that there has been no impairment in goodwill or indefinite-lived assets in 2020. Product warranty 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 variables used in the calculation of the provision are reviewed at least annually. At times, warranty issues may arise which are beyond the scope of our historical experience. We provide for any such warranty issues as they become known and estimable. While our warranty costs have historically been within calculated estimates, it is possible that future warranty costs could differ significantly from those estimates. The allocation of the warranty liability between current and 23 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, 2020 and 2019, our reserve for product warranties was $142.3 million and $134.3 million, respectively. Product liability Due to the nature of our products, we are subject to product liability 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 2020, we maintained a self-insured retention of $7.5 million per occurrence with an aggregate insurance limit of $125.0 million. We establish product liability reserves for our self-insured retention portion of any known outstanding matters based on the likelihood of loss and our ability to reasonably estimate such loss. There is inherent uncertainty as to the eventual resolution of unsettled matters due to the unpredictable nature of litigation. We make estimates based on available information and our best judgment after consultation with appropriate advisors and experts. We periodically revise estimates based upon changes to facts or circumstances. We also utilize an actuary 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, 2020 and 2019, our reserve for product liability was $35.3 million and $33.1 million, respectively. Pensions We have significant pension benefit costs that are developed from actuarial valuations. The valuations reflect key assumptions regarding, among other things, discount rates, expected return on plan assets, retirement ages, and years of service. Consideration is given to current market conditions, including changes in interest rates in making these assumptions. Our assumption for the expected return on plan assets was 6.75 and 7.15 percent in 2020 and 2019, respectively. The discount rate used to determine net periodic pension costs decreased to 3.18 percent in 2020 from 4.32 percent in 2019. For 2021, our expected return on plan assets is 6.25 percent and our discount rate is 2.44 percent. In developing our expected return on plan assets, we evaluate our pension plan’s current and target asset allocation, the expected long-term rates of return of equity and bond indices and the actual historical returns of our pension plan. Our plan’s target allocation to equity managers is approximately 30 to 60 percent, with the remainder allocated primarily to bond managers, private equity managers and real estate managers. Our actual asset allocation as of December 31, 2020, was 44 percent to equity managers, 46 percent to bond managers, nine percent to real estate managers, and one percent to private equity managers. We regularly review our actual asset allocation and periodically rebalance our investments to our targeted allocation when considered appropriate. Our pension plan’s historical ten-year and 25-year compounded annualized returns are 9.3 percent and 8.7 percent, respectively. We believe that with our target allocation and the expected long-term returns of equity and bond indices as well as our actual historical returns, our 6.25 percent expected return on plan assets for 2021 is reasonable. The discount rate assumptions used to determine future pension obligations at December 31, 2020 and 2019 were based on the Aon AA Only Above Median yield curve, which was designed by Aon to provide a means for plan sponsors to value the 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 assumptions at least annually, and we will adjust the assumptions as necessary. We recognized pension income of $5.1 million, $6.2 million, and $8.7 million in 2020, 2019, and 2018, respectively. We made changes to our pension plan including closing the plan to new entrants effective January 1, 2010, and the sunset of our plan for the majority of our employees on December 31, 2014. Lowering the expected return on plan assets by 25 basis points would decrease our net pension income for 2020 by approximately $1.9 million. Lowering the discount rate by 25 basis points would increase our 2020 net pension income by approximately $0.4 million. 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 a $23 million and $31 million obligation to pay and administer future annuity payments for certain retirees and beneficiaries in 2020 and 2019, respectively. 24 Non-GAAP Measures We provide non-GAAP measures (adjusted earnings, adjusted earnings per share (EPS) and adjusted segment earnings) that exclude severance, restructuring and impairment expenses in 2020 and 2018. We believe that the measures of adjusted earnings, adjusted EPS, and adjusted segment earnings provide useful information to investors about our performance and allow management and our investors to better understand our performance between periods without regard to items we do not consider to be a component of our core operating performance.

In 2018, we recognized $6.7 million of restructuring and impairment expenses in connection with the move of manufacturing operations from our Renton, Washington facility to other U.S. facilities. For additional information, see Note 5 of Notes to Consolidated Financial Statements. In 2020, we recognized $5.0 million of severance and restructuring expenses in connection with our alignment of the business to current market conditions. For additional information, see Note 5 of Notes to Consolidated Financial Statements. 25 Outlook We expect our consolidated sales to increase approximately ten percent in 2021. We believe the Chinese economy will improve in 2021 and expect that sales in China will increase by 20 to 21 percent in U.S. dollar terms and 14 to 15 percent in local currency terms. We expect to achieve full-year earnings of between $2.40 and $2.50 per share. Our 2021 guidance excludes the potential impacts from future acquisitions and assumes that the conditions of our business environment and that of our suppliers and customers are similar for the remainder of the year to what we have experienced in recent months and do not deteriorate as a result of further restrictions or shutdowns due to the COVID-19 pandemic. 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 2020 and we do not expect them to be material in any single year. We have reserves associated with environmental obligations at various facilities and we believe these reserves together with available insurance coverage are sufficient to cover reasonably anticipated remediation costs. Although we believe that our operations are substantially in compliance with such laws and maintain procedures designed to maintain compliance, there are no assurances that substantial additional costs for compliance will not be incurred in the future. However, since the same laws govern our competitors, we should not be placed at a competitive disadvantage. Risk Management 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 Enterprise Risk Management - Integrated Framework (2017) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). We believe that risk-taking is an inherent aspect of the pursuit of our strategy. Our goal is to manage risks prudently rather than avoid risks. We can mitigate risks and their impact on the Company only to a limited extent. A team of senior executives prioritizes identified risks and assigns an executive to address each major identified risk area and lead action plans to manage risks. Our Board of Directors provides oversight of the ERM process and reviews significant identified risks. The Audit Committee of the Board of Directors also reviews significant financial risk exposures and the steps management has taken to monitor and manage them. Our other Board committees also play a role in risk management, as set forth in their respective charters. Our goal is to proactively manage risks using a structured approach in conjunction with strategic planning, with the intent to preserve and enhance shareholder value. However, the risks set forth Item 1A - Risk Factors and elsewhere in this Annual Report on Form 10-K and other risks and uncertainties could adversely affect us and cause our results to vary materially from recent results or from our anticipated future results. Market Risk We are exposed to various types of market risks, primarily currency. We monitor our risks in such areas on a continuous basis and generally enter into forward contracts to minimize such exposures for periods of less than one year. 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, 2020, we had net foreign currency contracts outstanding with notional values of $229.9 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 $23.0 million. However, gains and losses from our forward contracts will be offset by gains and losses in the underlying transactions being hedged.

ITEM 7A – QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK See “Market Risk” above. 27 ITEM 8 – FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Directors and Stockholders A. O. Smith Corporation Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of A. O. Smith Corporation (the Company) as of December 31, 2020 and 2019, 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, 2020, and the related notes and financial statement schedule listed in the index at Item 15(a) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, 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, 2020, 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 12, 2021 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 Warranty Liability Valuation At December 31, 2020, the Company’s product warranty liability was $142.3 million. As discussed in Note 1 of the consolidated financial statements, the Company records a liability for the expected cost of warranty-related claims at the time of sale. The product warranty liability is estimated based upon warranty loss experience using actual historical failure rates and estimated cost of product replacement. Products generally carry warranties from one to 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 nature of the warranty loss experience assumptions, including the estimated product failure rate and the estimated cost of product replacement. In particular, it is possible that future product failure rates may not be reflective of 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 assumptions 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 assumptions 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 warranty 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. 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.

Organization and Significant Accounting Policies Organization. A. O. Smith Corporation (A. O. Smith or the Company) is comprised of two reporting segments: North America and Rest of World. The Rest of World segment is primarily comprised of China, Europe and India. Both segments manufacture and market comprehensive lines of residential and commercial gas and electric water heaters, boilers, tanks and water treatment products. Both segments primarily manufacture and market in their respective regions of the world. Consolidation. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries after elimination of intercompany transactions. Use of estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States (U.S.) requires management to make estimates and assumptions that affect the amounts reported in the accompanying financial statements and notes. Actual results could differ from those estimates. Fair value of financial instruments. The carrying amounts of cash, cash equivalents, marketable securities, receivables, floating rate debt and trade payables approximated fair value as of December 31, 2020 and 2019, due to the short maturities or frequent rate resets of these instruments. 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 for the same date. The fair value of term notes with insurance companies was approximately $122.1 million as of December 31, 2019 compared with the carrying amount of $120.0 million. Foreign currency translation. For all subsidiaries outside the U.S., with the exception of its Barbados, Hong Kong and Mexican companies and its non-operating companies in the Netherlands, the Company uses the local currency as the functional currency. For those operations using a functional currency other than the U.S. dollar, assets and liabilities were translated into U.S. dollars at year-end exchange rates, and revenues and expenses were translated at weighted-average exchange rates. The resulting translation adjustments were recorded as a separate component of stockholders’ equity. The Barbados, Hong Kong, Mexican and 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 2020, 2019, or 2018. 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, 2020, 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 and net realizable value. Cost is determined on the last-in, first- out (LIFO) method for a majority of the Company’s domestic inventories, which comprised 67 percent and 65 percent of the Company’s total inventory at December 31, 2020 and 2019, respectively. Inventories of foreign subsidiaries, the remaining domestic inventories and supplies were determined using the first-in, first-out (FIFO) method. Property, plant and equipment. Property, plant and equipment are stated at cost. Depreciation is computed primarily by the straight-line method. The estimated service lives used to compute depreciation are generally 25 to 50 years for buildings, three to 20 years for equipment and three to 15 years for software. Maintenance and repair costs are expensed as incurred. Goodwill and other intangibles. Goodwill and indefinite-lived intangible assets are not amortized but are reviewed for impairment on an annual basis. Separable intangible assets, primarily comprised of customer relationships, that are not deemed to have an indefinite life are amortized on a straight-line basis over their estimated useful lives which range from 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 carrying amount may not be recoverable. If the sum of the expected undiscounted cash flows is less than the carrying value of the related asset or group of assets, a loss is recognized for the difference between the fair value and carrying value of the asset or group of assets. Such analyses necessarily involve 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 for any such warranty issues as they become known and estimable. The allocation of the warranty liability between current and long-term is based on expected warranty claims to be paid in the next year as determined by historical product failure rates. The following table presents the Company’s product warranty liability activity in 2020 and 2019: Years ended December 31 (dollars in millions) Balance at beginning of year Expense Claims settled Balance at end of year 2020 2019 $ $ 134.3 $ 56.1 (48.1) 142.3 $ 139.4 44.3 (49.4) 134.3 Derivative instruments. The Company utilizes certain derivative instruments to enhance its ability to manage currency as well as raw materials price risk. The Company does not enter into contracts for speculative purposes. The fair values of all derivatives are recorded in the consolidated balance sheets. The change in a derivative’s fair value is recorded each period in current earnings or accumulated other comprehensive loss (AOCL), depending on whether the derivative is designated as part of a hedge transaction and if so, the type of hedge transaction. See Note 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 Value Measurements, among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring basis or nonrecurring basis. ASC 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. Assets and liabilities measured at fair value are based on the market approach which are prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. Assets measured at fair value on a recurring basis are as follows (dollars in millions): Fair Value Measurement Using Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2) December 31, 2020 December 31, 2019 $ 116.5 $ (4.3) 177.4 6.9 There were no changes in the valuation techniques used to measure fair values on a recurring basis. Revenue recognition. Substantially all of the Company’s sales are from contracts with customers for the purchase of its products. Contracts and customer purchase orders are used to determine the existence of a sales contract. Shipping documents are used to verify shipment. For substantially all of its products, the Company transfers control of products to the customer at the point in time when title and risk are passed to the customer, which generally occurs upon shipment of the product. See Note 2, “Revenue Recognition” for disclosure of the Company’s revenue recognition activities. Advertising. The majority of advertising costs are charged to operations as incurred and totaled $97.0 million, $110.7 million and $132.1 million during 2020, 2019 and 2018, respectively. Included in total advertising costs are expenses associated with store displays for water heater, water treatment and air purification products in China that are amortized over 12 to 36 months which totaled $27.0 million, $28.5 million and $38.7 million during 2020, 2019 and 2018, respectively. Research and development. Research and development costs are charged to operations as incurred and amounted to $80.7 million, $87.9 million and $94.0 million during 2020, 2019 and 2018, respectively. Environmental costs. The Company accrues for costs associated with environmental obligations when such costs are probable and reasonably estimable. Costs of estimated future expenditures are not discounted to their present value. 35 1. Organization and Significant Accounting Policies (continued) Recoveries of environmental costs from other parties are recorded as assets when their receipt is considered probable. The accruals are adjusted as facts and circumstances change. Stock-based compensation. Compensation cost is recognized using the straight-line method over the vesting period of the award and forfeitures are recognized as they occur. In accordance with amended ASC 718, the Company recognized $4.2 million, $2.3 million, and $2.4 million of discrete income tax benefits on settled stock based compensation awards during 2020, 2019, and 2018 respectively. Income taxes. The provision for income taxes is computed using the asset and liability method, in accordance with ASC 740 Income Taxes, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities and for operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled and are classified as noncurrent in the consolidated balance sheet. The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon settlement. Earnings per share of common stock. The Company is not required to use the two-class method of calculating earnings per share since its Class A Common Stock and Common Stock have equal dividend rights. The numerator for the calculation of basic and diluted earnings per share is net earnings. The following table sets forth the computation of basic and diluted weighted-average shares used in the earnings per share calculations: Denominator for basic earnings per share - weighted-average shares Effect of dilutive stock options, restricted stock and share units Denominator for diluted earnings per share Recent Accounting Pronouncements. 2020 161,530,589 1,073,560 162,604,149 2019 165,450,441 1,260,456 166,710,897 2018 170,589,345 1,604,695 172,194,040 In December 2019, the Financial Accounting Standards Board (FASB) amended Accounting Standards Codification (ASC) 740, Income Taxes (issued under Accounting Standards Update (ASU) 2019-12, “Simplifying the Accounting for Income Taxes”). This amendment removes certain exceptions to the general principles of ASC 740, and clarifies and amends existing guidance to improve consistent application. The amendment requires adoption on January 1, 2021. The Company does not expect that the adoption of ASU 2019-12 will have a material impact on its consolidated balance sheets, statements of earnings or statements of cash flows. In January 2017, the FASB amended ASC 350, Intangibles – Goodwill and Other (issued under ASU 2017-4, “Simplifying the Test for Goodwill Impairment”). This amendment simplifies the test for goodwill impairment by only requiring an entity to perform an annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount that the carrying amount exceeds the reporting unit’s fair value. Any loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The Company adopted the amendment on January 1, 2020 and the adoption did not have an impact on its consolidated balance sheets, statements of earnings or statements of cash flows. In June 2016, the FASB issued ASC 326, Financial Instruments – Credit Losses (issued under ASU 2016-13) which modifies the measurement of expected credit losses on certain financial instruments. The Company adopted ASU 2016-13 on January 1, 2020 and the adoption did not have a material impact on its consolidated balance sheets, statements of earnings or statements of cash flows. 2. Revenue Recognition Substantially all of the Company’s sales are from contracts with customers for the purchase of its products. Contracts and customer purchase orders are used to determine the existence of a sales contract. Shipping documents are used to verify shipment. For substantially all of its products, the Company transfers control of products to the customer at the point in time when title and risk are passed to the customer, which generally occurs upon shipment of the product. Each unit sold is considered an independent, unbundled performance obligation. The Company’s sales arrangements do not include other 36 2. Revenue Recognition (continued) performance obligations that are material in the context of the contract. The nature, timing and amount of revenue for a respective performance obligation are consistent for each customer. The Company measures the sales transaction price based upon the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. Sales and value added taxes are excluded from the measurement of transaction price. The Company’s payment terms for the majority of its customers are 30 to 90 days from shipment. Additionally, certain customers in China pay the Company prior to the shipment of products resulting in a customer deposits liability of $90.0 million and $49.6 million at December 31, 2020 and December 31, 2019, respectively. Customer deposit liabilities are short-term in nature and are recognized into revenue within one year of receipt. The Company assesses the collectability of customer receivables based on the creditworthiness of a customer as determined by credit checks and analysis, as well as the customer’s payment history. In determining the allowance for doubtful accounts, the Company also considers various factors including the aging of customer accounts and historical write-offs. In addition, the Company monitors other risk factors including forward-looking information when establishing adequate allowances for doubtful accounts, which reflects the current estimate of credit losses expected to be incurred over the life of the receivables. The Company’s allowance for doubtful accounts was $5.6 million at December 31, 2020 and $6.7 million at December 31, 2019. Rebates and incentives are based on pricing agreements and are tied to sales volume. The amount of revenue is reduced for variable consideration related to customer rebates which are calculated using expected values and are based on program specific factors such as expected rebate percentages based on expected volumes. In situations where the customer has the right to return eligible products, the Company reduces revenue for its estimates of expected product returns, which are primarily based on an analysis of historical experience. Changes in such accruals may be required if actual sales volume differs from estimated sales volume or if future returns differ from historical experience. Shipping and handling costs billed to customers are included in net sales and the related costs are included in cost of products sold and are activities performed to fulfill the promise to transfer products. Disaggregation of Net Sales The Company is comprised of two reporting segments: North America and Rest of World. The Rest of World segment is primarily comprised of China, Europe and India. 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. As each segment manufactures and markets products in its respective region of the world, the Company has determined that geography is the primary factor in reporting its sales. The Company further disaggregates its North America segment sales by major product line as each of North America’s major product lines is sold through distinct distribution channels and these product lines may be impacted differently by certain economic factors. Within the Rest of World segment, particularly in lines, utilizing the same China and India, distribution channels regardless of product type. In addition, the impact of economic factors is unlikely to be differentiated by product line in the Rest of World segment. the Company’s major customers purchase across the Company’s product The North America segment major product lines are defined as the following: Water heaters The Company’s water heaters are open water heating systems that heat potable water. Typical applications for water heaters include residences, restaurants, hotels and motels, office buildings, laundries, car washes and small businesses. The Company sells residential and commercial water heater products and related parts through its wholesale distribution channel, which includes more than 1,200 independent wholesale plumbing distributors. The Company also sells residential water heaters and related parts through retail and maintenance, repair and operations (MRO) channels. A significant portion of the Company’s water heater sales in the North America segment is derived from the replacement of existing products. Boilers The Company’s boilers are closed loop water heating systems used primarily for space heating or hydronic heating. The Company’s boilers are primarily used in applications in commercial settings for hospitals, schools, hotels and other large commercial buildings while residential boilers are used in homes, apartments and condominiums. The Company’s boiler distribution channel is comprised primarily of manufacturer representative firms, with the remainder of its boilers distributed through wholesale channels. The Company’s boiler sales in the North America segment are derived from a combination of replacement of existing products and new construction. Water treatment products The Company’s water treatment products range from point-of-entry water softeners, solutions for problem well water, and whole-home water filtration products to on-the-go filtration bottles and point-of-use carbon and reverse osmosis products. Typical applications for the Company’s water treatment products include residences, restaurants, hotels and offices. The Company sells water treatment products through its retail and wholesale distribution channels, similar 37 2. Revenue Recognition (continued) to water heater products and related parts. The Company’s water treatment products are also sold through independent water quality dealers as well as directly to consumers including through internet sales channels. A portion of the Company’s sales of water treatment products in the North America segment is comprised of replacement filters. The following table disaggregates the Company’s net sales by segment. As described above, the Company’s North America segment sales are further disaggregated by major product line. In addition, the Company’s Rest of World segment sales are disaggregated by China and all other Rest of World.

Acquisition On April 8, 2019, the Company acquired 100 percent of the shares of Water-Right, a Wisconsin-based water treatment company. With the addition of Water-Right, the Company grew its North America water treatment platform. Water-Right is included in the Company’s North America segment. The Company paid an aggregate cash purchase price of $107.0 million, net of cash acquired. In addition, the Company established a $4.0 million escrow to satisfy any potential obligations of the former owners of Water-Right, should they arise. During 2020, the Company released $3.9 million of the escrow to the previous owners of Water-Right. The remaining balance of $0.1 million is scheduled to be disbursed in the second quarter of 2021. The following table summarizes the allocation of the fair value of the assets acquired and liabilities assumed at the date of acquisition of Water-Right for purposes of allocating the purchase price. Significant assumptions used to estimate the fair value of intangible assets acquired include discount rates and certain assumptions that form the basis of the forecasted results, including revenue growth rates, attrition rates and royalty rates. The $60.4 million of acquired identifiable intangible assets was comprised of the following: $40.2 million of customer relationships being amortized over 20 years, $19.0 million of trademarks not subject to amortization, and $1.2 million of non-compete agreements being amortized over 7.5 years.

Leases The Company’s lease portfolio consists of operating leases for buildings and equipment, such as forklifts and copiers, primarily in the United States and China. The Company defines a lease as a contract that gives the Company the right to control the use of a physical asset for a stated term. The Company pays the lessor for that right, with a series of payments defined in the contract and a corresponding right of use operating lease asset and liability are recorded. The Company has elected not to record leases with an initial term of 12 months or less on its consolidated balance sheet. To determine balance sheet amounts, required legal payments are discounted using the Company’s incremental borrowing rate as of the inception of the lease. The incremental borrowing rate is the rate of interest that the Company would incur if it were to borrow, on a collateralized basis, an amount equal to the value of the leased item over a similar term, in a similar economic environment. Variable lease components not based on an index or rate are excluded from the measurement of the lease asset and liability and expensed as incurred for all asset classes. Certain leases include one or more options to renew or terminate. Renewal terms can extend the lease term from one to five years and options to terminate can be effective within one year. The exercise of lease renewal or termination is at the Company’s discretion and when it is determined to be reasonably certain to renew or terminate, the option is reflected in the measurement of lease asset and liability. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants or material subleases. Cash flows associated with leases are materially consistent with the expense recorded in the condensed consolidated statement of earnings. Supplemental balance sheet information related to leases is as follows: (dollars in millions) Liabilities Short term: Accrued liabilities Long term: Operating lease liabilities Total operating lease liabilities Less: Rent incentives and deferrals Assets Operating lease assets Lease Term and Discount Rate Weighted-average remaining lease term Weighted-average discount rate The components of lease expense were as follows: December 31, 2020 December 31, 2019 $ $ $ 11.1 $ 34.4 45.5 $ (3.9) 41.6 $ 12.0 38.7 50.7 (3.8) 46.9 December 31, 2020 10 years 3.49% (dollars in millions) Lease Expense(1) Operating lease expense Classification Cost of products sold Selling, general and administrative expenses Year ended December 31, 2020 3.1 $ 16.0 Year ended December 31, 2019 3.0 $ 17.6 (1) Includes short-term lease expense of $1.8 million for the year ended December 31, 2020.

The facility has an accordion provision which allows it to be increased up to $700 million if certain conditions (including lender approval) are satisfied. Borrowings under the Company’s bank credit lines and commercial paper borrowings are supported by the revolving credit agreement. As a result of the long- term nature of this facility, the commercial paper and credit line borrowings are classified as long-term debt at December 31, 2019. As of December 31, 2020 there were no commercial paper or credit line borrowings. At its option, the Company either maintains cash balances or pays fees for bank credit and services. The company has fixed-rate interest expense obligations of $22.2 million on outstanding debt as of December 31, 2020. Scheduled maturities of long-term debt within each of the five years subsequent to December 31, 2020 are as follows: Years ending December 31 (dollars in millions) 2021 2022 2023 2024 2025 42 $ Amount 6.8 6.8 10.0 10.0 10.0 11. Stockholders’ Equity The Company’s authorized capital consists of three million shares of Preferred Stock $1 par value, 27 million shares of Class A Common Stock $5 par value, and 240 million shares of Common Stock $1 par value. The Common Stock has equal dividend rights with Class A Common Stock and is entitled, as a class, to elect one-third of the Board of Directors and has 1/10th vote per share on all other matters. Class A Common Stock is convertible to Common Stock on a one for one basis. There were 12,372 shares during 2020, 10,442 shares during 2019 and 48,232 shares during 2018, of Class A Common Stock converted into Common Stock. Regular dividends paid on the A. O. Smith Corporation Class A Common Stock and Common Stock amounted to $0.98, $0.90 and $0.76 per share in 2020, 2019 and 2018, respectively. In the second quarter of 2019, the Company's Board of Directors approved adding three million shares of Common Stock to an 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 capital requirements, general business conditions and other factors, including alternative investment opportunities. The stock repurchase authorization remains effective until terminated by the Board of Directors which may occur at any time, subject to the parameters of any Rule 10b5-1 automatic trading plan that the Company may then have in effect. Due to the uncertainty surrounding the impact of the global COVID-19 pandemic, the Company suspended its share repurchases on March 18, 2020. In 2020, the Company repurchased 1,348,391 shares at an average price of $42.02 per share and at a total cost of $56.7 million. As of December 31, 2020, there were 1,613,824 shares remaining on the existing repurchase authorization. In 2019, the Company repurchased 6,113,038 shares at a cost of $287.7 million. In 2018, the Company repurchased 3,797,800 shares at a cost of $202.6 million. At December 31, 2020, a total of 130,380 and 28,807,455 shares of Class A Common Stock and Common Stock, respectively, were held as treasury stock.

Stock Based Compensation The Company adopted the A. O. Smith Combined Incentive Compensation Plan (the Plan) effective January 1, 2007. The Plan was most recently reapproved by stockholders on April 15, 2020. The Plan is a continuation of the A. O. Smith Combined Executive Incentive Compensation Plan which was originally approved by stockholders in 2002. The number of shares available for granting of options or share units at December 31, 2020, was 3,395,216 which includes 2,400,000 additional shares that were authorized on April 15, 2020 at the Company's annual meeting of stockholders. Upon stock option exercise or share unit vesting, shares are issued from treasury stock. Total stock based compensation expense recognized in 2020, 2019 and 2018 was $12.7 million, $13.3 million and $10.1 million, respectively. Stock Options The stock options granted in 2020, 2019 and 2018 have three year pro rata vesting from the date of grant. Stock options are issued at exercise prices equal to the fair value of the Company’s Common Stock on the date of grant. For active employees, all options granted in 2020, 2019 and 2018 expire ten years after the date of grant. The Company’s stock options are expensed ratably over the three year vesting period. Included in stock option expense for 2020, 2019 and 2018 was $6.2 million, $6.4 million and $4.4 million, respectively. Included in the stock option expense recognized in 2020, 2019 and 2018 44 12. Stock Based Compensation (continued) is expense associated with the accelerated vesting of stock option awards for certain employees who either are retirement eligible or become retirement eligible during the vesting period. Changes in options, all of which relate to the Company’s Common Stock, were as follows: Years Ended December 31 2020 2019 2018 Weighted Avg. Per Share Exercise Price Number of Options Weighted Avg. Per Share Exercise Price Number of Options Weighted Avg.

(2) The weighted average remaining contractual life of options outstanding was 8 years at December 31, 2020, and 7 years at December 31, 2019, and December 31, 2018, respectively. The aggregate intrinsic value of options outstanding at December 31, 2020 was $35.3 million. (3) The weighted average remaining contractual life of options exercisable was 6 years at December 31, 2020, December 31, 2019 and December 31, 2018. The aggregate intrinsic value of options exercisable at December 31, 2020 was $23.7 million.

Assumptions were as follows: Expected life (years) Risk-free interest rate Dividend yield Expected volatility 2020 2019 2018 5.7 1.5 % 2.1 % 23.7 % 5.5 2.7 % 1.6 % 22.8 % 5.7 2.9 % 1.0 % 22.1 % The expected lives of options for purposes of these models are based on historical exercise behavior. The risk free interest rates for purposes of these models are based on the U.S. Treasury yield curve in effect on the date of grant for the respective expected lives of the option. The expected dividend yields for purposes of these models are based on the dividends paid in the preceding four quarters divided by the grant date market value of the Common Stock. The expected volatility for purposes of these models are based on the historical volatility of the Common Stock. 45 12. Stock Based Compensation (continued) Restricted Stock and Share Units Participants may also be awarded shares of restricted stock or share units under the Plan. Share units vest three years after the date of grant. The Company granted 174,420, 140,102 and 106,581 share units under the plan in 2020, 2019 and 2018, respectively. The share units were valued at $7.4 million, $6.9 million and $6.6 million at the date of issuance in 2020, 2019 and 2018, respectively, based on the price of the Company’s Common Stock at the date of grant. The share units are recognized as compensation expense ratably over the three-year vesting period; however, included in share unit expense was expense associated with accelerated vesting of share unit awards for certain employees who are retirement eligible or will become retirement eligible during the vesting period. Stock based compensation expense of $6.5 million, $6.9 million and $5.7 million was recognized in 2020, 2019 and 2018, respectively. Certain non-U.S.-based employees receive the cash value of the share price at the vesting date in lieu of shares. Unvested cash-settled awards are remeasured at each reporting period. A summary of share unit activity under the plan is as follows: Issued and unvested at January 1, 2020 Granted Vested Forfeited Issued and unvested at December 31, 2020 13.

The Company also has two foreign pension plans, neither of which is material to the Company’s financial position. The Company has a defined contribution plan which matches 100 percent of the first one percent of contributions made by participating employees and matches 50 percent of the next five percent of employee contributions. The Company also has defined contribution plans for certain hourly employees which provide for matching Company contributions. The Company also has a defined benefit plan for salaried employees and its non-union hourly workforce. In 2009, the Company announced U.S. employees hired after January 1, 2010, would not participate in the defined benefit plan, and benefit accruals for the majority of current salaried and hourly employees sunset on December 31, 2014. An additional Company contribution is made to the defined contribution plan in lieu of benefits earned in a defined benefit plan. The Company also has defined benefit and contribution plans for certain union hourly employees. The Company has unfunded defined-benefit post-retirement plans covering certain hourly and salaried employees that provide medical and life insurance benefits from retirement to age 65. Certain hourly employees retiring after January 1, 1996, are subject to a maximum annual benefit and salaried employees hired after December 31, 1993, are not eligible for post-retirement medical benefits. 46 13.

Pension and Other Post-retirement Benefits (continued) The Company’s investment policies employ an approach whereby a diversified blend of equity and bond investments is used to maximize the long-term return of plan assets for a prudent level of risk. Equity investments are diversified across domestic and non-domestic stocks, as well as growth, value, and small to large capitalizations. Bond investments include corporate and government issues, with short-, mid- and long-term maturities, with a focus on investment grade when purchased. The Company’s target allocation to equity managers is between 30 to 60 percent with the remainder allocated primarily to bonds, real estate, private equity managers and cash. Investment and market risks are measured and monitored on an ongoing basis through regular investment portfolio reviews, annual liability measurements and periodic asset/liability studies. The Company’s actual asset allocations are in line with target allocations. The Company regularly reviews its actual asset allocation and periodically rebalances its investments to the targeted allocation when considered appropriate. There was no Company stock included in plan assets at December 31, 2020. Cash Flows The Company was not required to and did not make any contributions in 2020. The Company is not required to make a contribution in 2021. Estimated Future Payments The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid: Years ended December 31 (dollars in millions) 2021 2022 2023 2024 2025 2026 – 2030 14.

Derivative instruments are entered into for periods consistent with the related underlying exposures and do not constitute positions independent of those exposures. The Company does not enter into contracts for speculative purposes. The contracts are executed with major financial institutions with no credit loss anticipated for failure of the counterparties to perform. Cash Flow Hedges With the exception of its net investment hedges, the Company designates all of its hedging instruments as cash flow hedges. For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), gains or losses on the derivative instrument are reported as a component of other comprehensive loss, net of tax, and are reclassified into earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings. Foreign Currency Forward Contracts The Company is exposed to foreign currency exchange risk as a result of transactions in currencies other than the functional currency of certain subsidiaries. The Company utilizes foreign currency forward purchase and sale contracts to manage the volatility associated with foreign currency purchases, sales and certain intercompany transactions in the normal course of business. Principal currencies for which the Company utilizes foreign currency forward contracts include the British pound, Canadian dollar, Euro and Mexican peso. Gains and losses on these instruments are recorded in accumulated other comprehensive loss, net of tax, until the underlying transaction is recorded in earnings. When the hedged item is realized, gains or losses are reclassified from accumulated other comprehensive loss to the consolidated statement of earnings. The assessment of effectiveness for forward contracts is based on changes in the forward rates. These hedges have been determined to be effective. 51 14. Derivative Instruments (continued) The majority of the amounts in accumulated other comprehensive loss for cash flow hedges are expected to be reclassified into earnings within one year. The following table summarizes, by currency, the contractual amounts of the Company’s foreign currency forward contracts that are designated as cash flow hedges: December 31 (dollars in millions) British pound Canadian dollar Euro Mexican peso Total Commodity Futures Contracts 2020 2019 Buy Sell Buy Sell — $ 1.0 $ — $ — 32.7 16.5 49.2 79.7 — — $ 80.7 $ — 36.0 18.6 54.6 $ 1.3 49.7 — — 51.0 $ $ In addition to entering into supply arrangements in the normal course of business, the Company also enters into futures contracts to fix the cost of certain raw material purchases, principally steel, with the objective of minimizing changes in cost due to market price fluctuations. The hedging strategy for achieving this objective is to purchase steel futures contracts on the New York Metals Exchange (NYMEX) and copper futures contracts on the open market of the London Metals Exchange (LME) or over the counter contracts based on the LME. With NYMEX, the Company is required to make cash deposits on unrealized losses on steel derivative contracts. There were no outstanding commodity futures contracts as of December 31, 2020 and 2019. Net Investment Hedges The Company enters into certain foreign currency forward contracts to hedge the exposure to a portion of the Company’s net investments in certain non-U.S. subsidiaries against the effect of exchange rate fluctuations on the translation of foreign currency balances to the U.S. dollar. For the derivative instruments that are designated and qualify as net investment hedges, gains and losses are reported in other comprehensive loss where they offset gains and losses recorded on the Company’s net investments in its non-U.S. subsidiaries. These hedges are determined to be effective. The Company recognized $(3.1) million and $— 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 2020 and 2019, respectively. The contractual amount of the Company’s foreign currency forward contracts that are designated as net investment hedges is $100.0 million as of December 31, 2020. The following tables present the impact of derivative contracts on the Company’s financial statements.

Among other things, U.S. Tax Reform reduced the U.S. corporate income tax rate to 21 percent commencing on January 1, 2018, implemented a territorial tax system and levied a one-time mandatory tax on undistributed earnings of foreign subsidiaries of U.S. companies. The Company completed its accounting for the income tax effects of U.S. Tax Reform as of December 31, 2018 and determined that there was no material adjustment necessary to the provisional amounts it recorded in 2017. As allowed under ASU 2018-02 Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, the Company has elected not to reclassify the income tax effects of U.S. Tax Reform from accumulated other comprehensive losses to retained earnings. 53 15.

As of December 31, 2020, $524.2 million of cash and cash equivalents and marketable securities were held by its foreign subsidiaries. The tax effects of temporary differences of assets and liabilities between income tax and financial reporting are as follows: December 31 (dollars in millions) Employee benefits Product liability and warranties Inventories Accounts receivable Property, plant and equipment Intangibles Environmental liabilities Undistributed foreign earnings Tax loss and credit carryovers All other Valuation allowance Net liability 2020 2019 Assets Liabilities Assets Liabilities $ $ 21.6 42.5 1.5 16.3 — — 1.9 — 20.3 9.9 (13.0) 101.0 $ — $ — — — 36.3 66.2 — 9.8 — — — $ $ 112.3 $ 11.3 27.3 39.7 — 16.3 — — 1.9 — 15.2 7.7 (11.9) 96.2 $ — — 0.3 — 34.9 61.3 — 20.8 — — — $ $ 117.3 21.1 The Company believes it is more likely than not that it will realize its net deferred tax assets through the reduction of future taxable income. The Company considered historical operating results in determining the probability of the realization of the deferred tax assets. A reconciliation of the beginning and ending amounts of tax loss carryovers, credit carryovers and valuation allowances is as follows: December 31 (dollars in millions) Beginning balance Increases / (Reductions) Ending balance Net Operating Losses and Tax Credits 2020 2019 Valuation Allowances 2019 2020 $ $ 15.2 5.1 20.3 $ $ 17.5 (2.3) 15.2 $ $ 11.9 1.1 13.0 $ $ 13.1 (1.2) 11.9 The Company has foreign net operating loss carryovers that expire in 2021 through 2028 and state and local net operating loss carryovers that expire between 2029 and 2030. 54 15. Income Taxes (continued) A reconciliation of the beginning and ending amount of unrecognized benefits is as follows: (dollars in millions) Balance at January 1 Additions / (Reductions) for tax positions of prior years Balance at December 31 2020 2019 $ $ 9.7 (0.7) 9.0 $ $ 8.3 1.4 9.7 The amount of unrecognized tax benefits that, if recognized, would affect the effective income tax rate is $0.5 million. The Company recognizes potential interest and penalties related to unrecognized tax benefits as a component of income tax expense. At December 31, 2020, there was an immaterial amount of interest and penalties accrued. The Company anticipates that there will not be a material decrease in the total amount of unrecognized tax benefits in 2021. The Company’s U.S. federal income tax returns and its U.S. state and local income tax returns are subject to audit for the years 2017-2020 and 2003-2020, respectively. The Company is subject to non-U.S. income tax audits for the years 2014-2020. 16. Commitments and Contingencies Environmental Contingencies The Company is a potentially responsible party in judicial and administrative proceedings seeking to clean up sites which have been environmentally impacted. In each case, the Company has established reserves, insurance proceeds and/or a potential recovery from third parties. The Company believes any environmental claims will not have a material effect on its financial position or results of operations. Product Liability The Company is subject to various claims and pending lawsuits for product liability and other matters arising out of the conduct of the Company’s business. With respect to product liability claims, the Company has self-insured a portion of its product liability loss exposure for many years. The Company has established reserves and has insurance coverage, which it believes are adequate to cover incurred claims. For the years ended December 31, 2020 and 2019, the Company had $125 million of product liability insurance for individual losses in excess of $7.5 million. The Company periodically reevaluates its exposure on claims and lawsuits and makes adjustments to its reserves as appropriate. The Company believes, based on current knowledge, consultation with counsel, adequate reserves and insurance coverage that the outcome of such claims and lawsuits will not have a material adverse effect on the Company’s financial position, results of operations or cash flows. Purchase Obligations The Company utilizes blanket purchase orders to communicate expected annual requirements to many suppliers. Requirements under blanket purchase orders generally do not become committed until several weeks prior to the scheduled unit production. The purchase obligations the Company considers firm as of December 31, 2020 is $157.2 million, most of which will be ordered in 2021. Inventory Repurchase Arrangements The Company maintains a commercial relationship with a supply-chain service provider (the Provider) in connection with the Company’s business in China. In this capacity, the Provider offers order-entry, warehousing and logistics support. The Provider also offers asset-backed financing to certain of the Company’s distributors in China to facilitate their working capital needs. To facilitate its financing support business, the Provider has collateralized lending facilities in place with multiple Chinese banks under which the Company has agreed to repurchase inventory if both requested by the banks and certain defined conditions are met, primarily related to the aging of the distributors’ notes. The Provider is required to indemnify the Company for any losses the Company would incur in the event of an inventory repurchase under these arrangements. Potential losses under the repurchase arrangements represent the difference between the repurchase price and net proceeds from the resale of product plus costs incurred in the process, less related distributor rebates. Before considering any reduction of distributor rebate accruals of $5.4 and $14.1 million as of December 31, 2020 and December 31, 2019, respectively, and from the resale of the related inventory, the gross amount the Company would be obligated to repurchase, which would be contingent on the default of all of the outstanding loans, was approximately $6.5 million and $23.1 million as of December 31, 2020 and December 31, 2019, respectively. The Company’s reserves for estimated losses under repurchase arrangements were immaterial as of December 31, 2020 and December 31, 2019. 55 17. Operations by Segment The Company is comprised of two reporting segments: North America and Rest of World. The Rest of World segment is primarily comprised of China, Europe and India. Both segments manufacture and market comprehensive lines of residential and commercial gas and electric water heaters, boilers, tanks and water treatment products.

Management Report on Internal Control Over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)). 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 issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on this evaluation, our management has concluded that, as of December 31, 2020, our internal control over financial reporting was effective. 57 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, 2020 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, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. ITEM 9B – OTHER INFORMATION None. 58 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Directors and Stockholders A. O. Smith Corporation Opinion on Internal Control over Financial Reporting We have audited A. O. Smith Corporation’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, A. O. Smith Corporation (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of A. O. Smith Corporation as of December 31, 2020 and 2019, and 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, 2020, and the related notes and financial statement schedule listed in the index at Item 15(a) and our report dated February 12, 2021 expressed an unqualified opinion thereon. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Ernst & Young LLP Milwaukee, Wisconsin February 12, 2021 59 PART III ITEM 10 – DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCE The information included under the headings “Election of Directors” and “Board Committees” in our definitive Proxy Statement for the 2021 Annual Meeting of Stockholders (to be filed with the Securities and Exchange Commission (SEC) under Regulation 14A within 120 days after the end of the registrant’s fiscal year) is incorporated herein by reference.
