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.

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.
