Energy Recovery (ERII) Stock Analysis & Winston Score

Energy Recovery makes devices that capture and reuse pressure energy that would otherwise be wasted in industrial processes. Its main product is the PX Pressure Exchanger, which is used in seawater desalination plants to dramatically cut the electricity needed to turn saltwater into drinking water. The company sells to water utilities, engineering firms, and industrial operators around the world. Energy Recovery earns revenue by selling its pressure exchanger devices and related equipment, with some additional income from service contracts. It operates globally, with a strong presence in the Middle East, where large desalination projects are common, as well as in the Americas and Europe. The company holds patents on its core technology, which gives it a durable competitive edge in a market where switching costs are high. The key growth driver is rising global demand for desalination as freshwater scarcity worsens, though the business is lumpy because it depends on large infrastructure projects that can be delayed or canceled.
