A. O. Smith Corporation AOS

AOS Company Overview

A. O. Smith Corporation is a global manufacturer specializing in water heating and water treatment solutions. The company operates primarily in the water technology and appliance manufacturing industries, with a focus on residential and commercial water heaters, boilers, and water purification products. Its core revenue drivers are the sale of water heating equipment and water treatment systems, supported by aftermarket parts and services. The company serves residential homeowners, commercial building owners, industrial customers, and distributors, with particularly strong positions in North America and Asia.

Founded in 1874 as a manufacturer of hardware and automotive components, A. O. Smith evolved into a water technology company through strategic divestitures and reinvestment in water-related products. Over several decades, it exited non-core businesses, including automotive components, to concentrate on water heating and treatment. This focused strategy has positioned the company as a leading global provider with brand recognition, manufacturing scale, and long-standing distributor relationships as key competitive advantages.
