WESTINGHOUSE AIR BRAKE TECHNOLOGIES CORP (WAB)

Westinghouse Air Brake Technologies Corporation, doing business as Wabtec, is a global provider of value-added, technology-based locomotives, equipment, systems and services for the freight rail and passenger transit industries, as well as mining, marine and industrial markets. Its roots go back to George Westinghouse's 1869 invention of the air brake. The company went public on the NYSE in 1995 and has grown through acquisitions including MotivePower (1999), Faiveley Transport (2017) and GE Transportation (2019). More recent deals include Evident's Inspection Technologies division and Frauscher Sensor Technology Group. Its engineered products, designed to improve safety and productivity and reduce maintenance costs, are found on most locomotives, freight cars, passenger transit cars and buses worldwide.

Wabtec reports two segments. The Freight Segment, about 72% of 2025 net sales, makes new and modernized locomotives, aftermarket parts and services, freight car components, rail control and infrastructure products (including positive train control equipment), heat exchangers and cooling systems, and software-enabled Digital Intelligence solutions. It also offers nondestructive testing and inspection instruments and train detection and axle counting systems. About 58% of Freight net sales are aftermarket. The Transit Segment, about 28% of net sales, makes and services components for regional and high-speed trains, subway cars, light-rail vehicles and buses. Its products include braking systems, HVAC, doors, couplers, pantographs, friction products, passenger information systems and signaling, and about 56% of its net sales are aftermarket. Across the company, aftermarket parts and services are about 60% of net sales, supported by an installed base of nearly 24,600 locomotives.

Freight customers include large publicly traded railroads, leasing companies, locomotive and freight car manufacturers, utilities, and mining, marine and industrial companies. Transit customers include public transit authorities and municipalities, leasing companies, vehicle and bus manufacturers, and electrical generation, distribution and charging companies. About 60% of Freight and 17% of Transit net sales are in the U.S. Operations span over 50 countries, and growth targets include Europe, India, Australia, Brazil, South Africa and Kazakhstan. Results depend on freight carloads, passenger ridership, government transit spending and railroad capital plans. Backlog was about $27.4 billion at December 31, 2025.
