## Summary

Leading water heater manufacturer with $3.5B revenue; heat pump water heaters growing rapidly with IRA tax credits and building electrification mandates.

## Company Overview

A. O. Smith is a global manufacturer of residential and commercial water heaters, boilers, and water treatment products sold under the A. O. Smith, State, American, and Lochinvar brands across North America, China, India, and Europe. Founded in 1874 and headquartered in Milwaukee, Wisconsin, A. O. Smith is listed on the NYSE and generates approximately $3.5 billion in annual revenue. The company is the largest water heater manufacturer in North America, holding approximately 38% market share, and the second largest in China through its Smith brand.

A. O. Smith's residential products range from traditional tank water heaters to heat pump water heaters (HPWHs), which are 2-3 times more energy efficient than conventional electric resistance models. The company has been a beneficiary of the energy transition push, as HPWH demand has surged with government incentives (IRA tax credits) and utility programs encouraging replacement of gas water heaters. Commercial products serve hotels, hospitals, restaurants, and apartment buildings with high-efficiency condensing water heaters and boilers.

In 2025, A. O. Smith has seen strong demand for heat pump water heaters as building electrification mandates expand in US cities and states and federal tax credits make upgrades economically attractive. The company has invested in manufacturing capacity for HPWHs and partnered with utilities running heat pump water heater programs. China operations, which had been a significant growth driver, have faced slower growth amid Chinese economic headwinds. A. O. Smith's 2025-2026 strategy focuses on HPWH growth in North America and India expansion as the rising middle class drives water heater market growth.
