Energy Recovery (NASDAQ: ERII) 2025 report details CO2 business wind-down
Energy Recovery, Inc. files its Annual Report for the year ended December 31, 2025, outlining its core business of pressure exchanger technology for desalination, wastewater treatment, and emerging applications.
The company’s Water segment remains its primary revenue driver, serving large "megaproject" seawater reverse osmosis plants and smaller OEM and aftermarket customers worldwide. It highlights growing opportunities in wastewater and ZLD/MLD applications, but also notes rising competition and exposure to project timing, financing, and geopolitical risks.
Within its Emerging Technologies segment, Energy Recovery decided on February 25, 2026 to wind down operations of its CO2 retail grocery business after a fundamental change in that business’s outlook. The report emphasizes ongoing R&D to extend pressure exchanger applications, strong sustainability positioning including a goal to cut Scope 1 and 2 emissions intensity by 65% by 2026, and a workforce of 230 full-time employees as of December 31, 2025.

Insights
Core water business stable; CO2 wind-down refocuses strategy.
Energy Recovery centers its model on pressure exchanger technology for desalination and wastewater, where it is widely adopted in seawater reverse osmosis plants and is pushing into ZLD/MLD wastewater applications. Revenue is concentrated in large, project-driven markets subject to financing, regulatory, and geopolitical swings.
The filing discloses a February 25, 2026 decision to wind down the CO2 retail grocery business in the Emerging Technologies segment after a fundamental outlook change, with associated costs and lost future CO2 revenue. This trims diversification but limits ongoing drag from an underperforming line.
Sustainability and R&D are emphasized: the company reports achieving its 2025 emissions-reduction goal early and targets a

•our belief that the pressure exchanger is the industry standard for energy recovery in the seawater reverse osmosis desalination (“SWRO”) industry; |
•our belief that the scalability and versatility of our PX® Pressure Exchanger® (“PX”) can help us achieve success in emerging wastewater markets; |
•our belief that the Ultra High-Pressure PX addresses key challenges associated with treating wastewater in a range of reverse osmosis (“RO”) applications; |
•our belief that the Ultra High-Pressure PX addresses key challenges, such as energy intensity and environmental impacts associated with treating wastewater; |
•our belief that the Ultra High-Pressure PX can help make RO the preferred treatment option to achieve zero and minimum liquid discharge (“ZLD” and “MLD”, respectively) requirements by enhancing RO’s affordability and efficiency compared to thermal treatment options; |
•our expectation of greater demand of our PX in the wastewater market due to expanding environmental regulations; |
•our belief that our hydraulic turbochargers deliver substantial savings, operational benefits and ease of integration into desalination systems; |
•our anticipation that markets not traditionally associated with desalination, such as the United States of America (the “U.S.”) and China will inevitably develop and provide further revenue growth opportunities; |
•our belief that countries around the world will continue to mandate ZLD or MLD requirements for specific industries; |
•our belief that, as the existing thermal technology is replaced with RO technology, demand for our products will be created; |
•our belief that our PX offers market-leading value with the highest technological and economic benefit; |
•our belief that ongoing operating costs and life cycle costs rather than the initial capital expenditures are the key factor in the selection of an energy recovery device solution for megaproject (“MPD”) customers; |
•our belief that our PX has a distinct competitive advantage in the market for desalination plants and numerous wastewater market verticals, because our PX 1) has minimal unplanned and planned downtime, resulting in lower lifecycle maintenance cost, 2) is a cost-effective energy recovery solution, 3) is made with highly durable and corrosion-resistant aluminum oxide (“alumina”) ceramic parts and outperforms our competition with respect to quality, flexibility and durability, and 4) is warrantied for high efficiencies; |
•our belief that leveraging our pressure exchanger technology will unlock new commercial opportunities in the future; |
•our belief that our PX G1300® can contribute to help make CO2-based refrigeration more economically viable in a broader range of climates; |
•our expectation that once the PX G1300 is established, our belief that our sales process will organically evolve; |
•our belief that competitive technologies to the PX G1300 could arise as CO2-based refrigeration systems become more prevalent; |
•our belief that our current facilities will be adequate for the foreseeable future; |
•our belief that by investing in research and development, we will be well positioned to continue to execute on our product strategy; |
•our belief that our technology helps our customer achieve environmentally sustainable operations; |
•our expectation that sales outside of the U.S. will remain a significant portion of our revenue; |
•the scale of the environmental impact from the use of our solutions; |
•our belief that the integration of sustainability principles into our corporate and risk management strategies can strengthen our existing business as well as our efforts to develop new applications of pressure exchanger technology for high-pressure fluid- flow environments; |
•the timing of our receipt of payment for products or services from our customers; |
•our belief that our existing cash and cash equivalents, our short and/or long-term investments, and the ongoing cash generated from our operations, will be sufficient to meet our anticipated liquidity needs for the foreseeable future, with the exception of a decision to enter into an acquisition and/or fund investments in our latest technology arising from rapid market adoption that could require us to seek additional equity or debt financing; |
•our expectations relating to the amount and timing of recognized revenue from our projects; |
•our expectation that, as we expand our international sales, a portion of our revenue could be denominated in foreign currencies and the impact of changes in exchange rates on our cash and operating results; |
•our expectation of increased sales and lower marketing expenditures for 2026; |
•our expectation that we will continue to receive a tax benefit related to U.S. federal foreign-derived intangible income and research and development tax credit; |
•our expectation that we will be able to enforce our intellectual property (“IP”) rights; |
•our expectation that the adoption of new accounting standards will not have a material impact on our financial position or results of operations; |
•the outcome of proceedings, lawsuits, disputes and claims; |
•the impact of losses due to indemnification obligations; |
•other factors disclosed under Part I, Item 1, “Business,” Item 1A, “Risk Factors,” and Item 2, “Properties,” and Part II, Item 7, MD&A, and Item 7A, “Quantitative and Qualitative Disclosures about Market Risk,” and elsewhere in this Form 10‑K. |
