The story

Founded by Arthur Oliver Smith in 1889, in Milwaukee.1

History

The company today known as the A. O. Smith Corporation was founded in 1874 by Charles Jeremiah Smith as C. J. Smith and Sons, a baby carriage and bicycle parts manufacturer. It began forming steel tubing from sheet metal to make bicycle frames. By 1895, the company was the largest bicycle parts manufacturer. In 1899, Arthur Oliver Smith, a son of the founder, developed the world's first pressed steel vehicle frame and he later began making frames for the Peerless Automobile Company, Cadillac, and Ford Motor Company. In 1904, the company incorporated in Milwaukee, Wisconsin, as A. O. Smith Company.

In 1913, Lloyd Raymond Smith took over, and in 1914, the company introduced the Smith Motor Wheel, a gasoline-powered device for bicycles.

In 1915, it began manufacturing the Smith Flyer automobile, which it later sold to Briggs & Stratton of Milwaukee.

In 1916, A. O. Smith was incorporated in New York.

In the 1920s, company engineers developed the coated welding rod which they used in manufacturing until 1965, as well as the world's first fully automated automobile frame factory, with the capability of making a frame every eight seconds, until 1958, the first arc-welded, high-pressure vessel used to refine oil, which the company produced until 1963, and oil supply line pipes, until 1972.

In 1933, the company used the process of fusing glass to steel to make a large single-piece glass-lined brewery tank. Over the next 32 years, it made more than 11,000 glass-lined tanks. In 1936, the company patented the glass-lined water heater. Three years later, it began mass-producing residential water heaters, but shifted all production to war-time use during World War II.

By 1945, the company had built 4.5 million bombs, 16,750 sets of landing gear, and 46,700 propeller blades. It also built nose frames for the B-25 bomber, water heaters, jeep frames, and components for the atomic bomb project. In 1946, it built a 400,000 square foot residential water heater plant in Kankakee, Illinois. From this plant, it also made water heaters with the Kenmore name. In 1948, it entered the commercial water heater market after acquiring The Burkay Company of Toledo, Ohio. In 1949, the company began producing Harvestore, a glass-fused-to-steel silo, targeted at dairy and livestock operations.

In the 1950s, A. O. Smith acquired Whirl-A-Way Motors of Dayton, Ohio, and consolidated its electric motor manufacturing operations there. The motor division later introduced the hermetic motor, a critical component of air conditioning and refrigeration compressors. Its water heater division introduced the first glass-lined commercial water heater, the A. O. Smith Burkay B-65, and later the company established a glass fiber division to replace steel in many applications. It also expanded into supplying oil field pipe and pipe for service stations, eventually becoming Smith Fiberglass Products in 1986.

In the early 1960s, the company opened a commercial water heater and boiler plant in Stratford, Ontario, Canada. In 1965, the Motor division invented the enclosed canopy, two-compartment motor, a design that improved the reliability in pool pump motors by separating the switching components from the motor windings. In 1967, fourth generation Smith family member, Lloyd B. Smith, was elected chairman and chief executive officer of the company. By 1969, the company had produced its 10 millionth residential water heater, and by 1972 had expanded to Europe. In 1974, the Conservationist line of residential water heaters was introduced. In 1976, the Motor division opened a plant in Bray, Ireland, to supply hermetic motors. In 1978, A. O. Smith began manufacturing storage tanks, beginning with Aquastore, a glass-fused-to-steel tank.

By the early 1980s, the Automotive Products unit had manufactured over 100 million passenger car frames, and 50 million truck frames, in Milwaukee, and soon after the company opened its first electric motor assembly operations in Ciudad Juárez and Ciudad Acuña, Mexico. In 1990, it developed the first hermetic motor insulation system compatible with R-134a non-ozone-depleting refrigerant. In 1995, they acquired Peabody TecTank of Parsons, Kansas, allowing A. O. Smith to enter the bulk dry storage market. That same year the company expanded into Asia through joint ventures: Smith Fiberglass Products and Harbin Composites Corporation to make fiberglass pipes for China's petroleum industry, as well as Water Products Company and Yuhan Water Heater to manufacture residential water heaters. In 1996, the Water Products division introduced the Cyclone XHE commercial water heater. In 1997, after 90 years in the automotive industry, A. O. Smith sold its Automotive Products Company to Tower International. In 1997, they acquired UPPCO, Inc., making A. O Smith the world's leading manufacturer of C-frame subfractional horsepower motors. In 1998, they acquired General Electric's domestic compressor motor business, as well as the electric motor division of Magnetek. By the end of the decade, Water Products Company had bought out its joint venture partner in Asia, and had opened a plant in Nanjing, China.

In the 2000s, A. O. Smith made a number of acquisitions, by acquiring State Industries, Inc., and its subsidiary APCOM Inc., Shenzhen Speeda Industrial Co. Ltd., and Athens Products, a supplier of hermetic motors for scroll compressor applications, as well as The Changheng Group of Changzhou, China, a manufacturer of fractional horsepower motors for HVAC applications, Taicang Special Motor Company, Ltd., of Suzhou, China, Yueyang Zhongmin Special Electrical Machinery Co. Ltd., Lochinvar Corporation, a manufacturer of high efficiency condensing boilers for hot water and hydronic heating applications, and in 2006, GSW Inc. a water heaters manufacturer for the Canadian market, and The American Water Heater Company, the exclusive supplier of water heaters to Lowe's, carrying the Whirlpool brand. In 2009, the company entered the water purification industry with a new venture, A. O. Smith (Shanghai) Water Treatment Products Co. Ltd. In 2010, A. O. Smith opened a 76,000 square foot residential water-heater manufacturing plant in Bengaluru, India, which later expanded to 297000 square foot operation with expansion to manufacture of water purification products. Takagi Industrial Company's North American operations were acquired in 2010. In 2011, A. O. Smith sold its electric motor business to Regal-Beloit.

On August 8, 2016, A. O. Smith, acquired Austin-based water filtration company Aquasana (previously known as Sun Water Systems) from L' Catterton for $87 Million.

In November 2024, A. O. Smith finalized the acquisition of Pureit, the water purification business of Hindustan Unilever for ₹600 crore.

Risk factors and legal proceedings

The risks A. O. Smith names in Item 1A of its 10-K filed Feb 10, 2026: 20 risks under these headings, as written.21

  • Economic and Industry Risks
  • ■The effects of global and regional economic conditions could have a material adverse effect on our business
  • ■Import tariffs, taxes, customs duties and other trading regulations imposed by the U.S. government and retaliatory responses from other countries, could significantly increase the prices we pay for raw materials that are critical to our ability to manufacture our products
  • ■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
  • ■Because we participate in markets that are highly competitive, our revenues and earnings could decline as we respond to competition
  • ■Our operations could be adversely impacted by material and component price volatility, as well as supplier concentration
  • ■Our business could be adversely impacted by changes in consumer purchasing behavior, consumer preferences, technological changes, and market trends
  • ■Because approximately 18 percent of our sales in 2025 were attributable to China, adverse economic conditions or changes in consumer behavior in China could impact our business
  • 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
  • ■A material loss, cancellation, reduction, or delay in purchases by one or more of our largest customers could harm our business
  • ■A portion of our business could be adversely affected by a further decline in North American new residential or commercial construction or a decline in replacement-related volume of water heaters and boilers, including a decline in demand for commercial spaces
The other 10 risks
  • ■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
  • ■Our international operations are subject to risks related to foreign currencies
  • ■Our business may be adversely impacted by product defects
  • ■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
  • Legal, Regulatory, and Governance Risks
  • ■Changes in regulations or standards, such as those associated with climate change, could adversely affect our business
  • ■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
  • ■Our sustainability commitments could result in additional costs, and our inability to achieve them could have an adverse impact on our reputation and performance
  • ■Our results of operations may be negatively impacted by product liability lawsuits and claims
  • ■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
  • ■Certain members of the founding family of our company and trusts for their benefit have the ability to influence all matters requiring stockholder approval

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 15, “Commitments and Contingencies” of Notes to the Consolidated Financial Statements.
