Thesis
Energy Recovery is a desalination infrastructure company trading at a 52-week low (~$11) after abandoning its CO2 business and missing guidance. The stock decline has created a potential value opportunity in essential infrastructure. The secular tailwind is global water scarcity. Desalination capacity is growing at 5-8% annually as freshwater sources deplete and populations grow. Energy Recovery's pressure exchanger technology reduces desalination energy costs by up to 60%, making it a critical component in essentially every large-scale reverse osmosis desalination plant globally. The company holds ~95% market share in energy recovery devices for seawater desalination. The abandonment of the CO2 business, while a near-term negative (showing failed diversification), actually simplifies the investment thesis. This is now a pure play on desalination infrastructure growth. At the current depressed valuation, the market is penalizing the company for the diversification failure while potentially undervaluing the core desalination franchise. Risks include that the stock may be cheap for a reason (structural margin pressure, competition from Chinese manufacturers), the missed guidance suggests potential demand softness, and the desalination market grows steadily rather than explosively.
