Westport is a technology company that designs, manufactures, and supplies advanced fuel systems and components enabling commercial transportation to transition from traditional fuels to alternative energy sources including natural gas, renewable natural gas, and hydrogen. The company operates through two main segments: Cespira, a joint venture with Volvo that develops integrated HPDI fuel systems for heavy-duty diesel engines, and High-Pressure Controls, which manufactures regulators, valves, and electronic control components for fuel-cell vehicles, hydrogen engines, and natural gas platforms across passenger vehicles, buses, trucks, industrial equipment, and rail. Westport generates revenue through long-term supply contracts with original equipment manufacturers, bus producers, and industrial equipment makers, leveraging proprietary technology in fuel delivery, combustion, and control systems to help customers meet performance, regulatory, and climate objectives cost-effectively.
