The company’s Water segment remains its primary revenue driver, serving large "megaproject" seawater reverse osmosis plants and smaller OEM and aftermarket customers worldwide.

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.
Energy Recovery, Inc. reported fourth quarter and full-year 2025 results and decided to wind down its CO2 retail grocery business within the Emerging Technologies segment.

For Q4 2025, revenue was $66.9 million, essentially flat year over year, while gross margin was 67.2% and operating margin improved to 46.8%.

Full-year 2025 revenue was $135.0 million, down 7% from 2024, with net income of $23.0 million and adjusted net income of $31.2 million.
The CO2 retail grocery wind-down is expected to be substantially complete by the end of the first quarter of 2026 and to generate $4.5 million to $5.5 million in one-time costs, including $1.0 million to $2.0 million of cash severance and several non-cash charges such as inventory reserves and goodwill impairment.
