Does ERII pay dividends?
No — Energy Recovery, Inc. does not currently pay a dividend.
Energy Recovery does not currently pay a dividend. For a smaller industrial technology company still expanding into emerging markets like CO2 refrigeration and industrial wastewater, retaining capital to fund product development and market penetration is a common strategic choice. Income-focused investors should factor this into their assessment.
When does ERII report earnings?
Energy Recovery reports earnings on a quarterly cadence, consistent with standard practice for US-listed equities.
Results have reflected the company's dual focus on its established water segment and its longer-horizon emerging technologies segment. Revenue trends in desalination can be lumpy given the project-based nature of large infrastructure contracts.

ERII Long-term Outlook
The UQS Growth pillar rates as Weak, suggesting the near-term revenue trajectory faces headwinds or uncertainty. However, the Strong Risk rating indicates the company enters any slower-growth period from a position of financial stability. The emerging technologies segment — spanning CO2 refrigeration and industrial wastewater — represents a longer-dated growth option that is not yet reflected in the core business fundamentals.
Growth drivers
- Expanding global demand for fresh water driving desalination project pipelines
- Emerging Technologies segment penetrating CO2 refrigeration and industrial wastewater markets
- Aftermarket services and spare parts providing recurring revenue alongside project cycles
Key risks
- Weak Moat rating signals limited pricing power if competition intensifies
- Project-based revenue in desalination creates lumpy, hard-to-predict quarters
- Emerging Technologies segment remains early-stage with uncertain commercialization timelines
ERII vs Peers
Energy Recovery operates in a niche corner of the industrials sector, but several companies address overlapping themes of environmental efficiency and industrial water treatment.
PureCycle focuses on plastic waste purification rather than water or energy recovery, targeting the circular economy through polymer recycling technology.
CECO provides industrial air quality and fluid handling solutions, competing in the broader environmental and industrial process equipment space.
Euro Tech focuses on water and wastewater treatment solutions primarily in China, serving a geographically distinct but thematically similar market.

Is ERII a good stock to buy?
UQS Score rates ERII as Good overall. The Risk pillar is Strong and both Quality and Valuation rate as Good, which are constructive signals. However, the Moat and Growth pillars are both Weak, indicating areas of concern. Whether that profile fits your investment goals depends on your own risk tolerance and time horizon.

The UQS Valuation pillar rates ERII as Good, suggesting the stock is not obviously overpriced relative to its fundamentals. That said, valuation is one of five pillars — the full picture requires weighing it alongside Quality, Growth, Moat, and Risk. Pro members can view the complete breakdown.
How does ERII compare to its competitors?
Energy Recovery occupies a specialized niche in pressure energy recovery for desalination, which differentiates it from broader environmental services peers like CECO Environmental or geographically focused players like Euro Tech Holdings. Its Weak Moat rating, however, suggests that competitive advantages may not be as durable as the niche positioning implies.
What is ERII's market cap bracket?
Energy Recovery is classified as a small-cap company. This means it carries higher volatility risk than large- or mega-cap industrials, but may also offer more room for growth if its emerging technologies segment gains commercial traction.
Who founded Energy Recovery?
Energy Recovery was incorporated in 1992. Details on its founding team are publicly available through the company's official history and SEC filings for investors who want to research the leadership background.
Is ERII a long-term quality stock?
As a long-term quality indicator, ERII's profile is mixed. The Strong Risk rating and Good Quality score suggest financial resilience, but the Weak Moat and Weak Growth ratings raise questions about whether the business can compound value over time. The emerging technologies segment could change that picture, but it remains unproven at scale.
What is the main competitive advantage of Energy Recovery?
Energy Recovery's core advantage is its Pressure Exchanger technology, which is deeply embedded in large-scale desalination infrastructure. Switching costs in installed plants are high. However, the UQS Moat pillar rates as Weak, suggesting that this advantage may face pressure as the competitive landscape evolves.
What sector does ERII belong to?
Energy Recovery is classified in the Industrials sector. More specifically, it operates at the intersection of water infrastructure and energy efficiency technology — a niche that also draws interest from environmental and clean-technology investors.
Is ERII a growth stock or value stock?
Based on UQS pillar labels, ERII leans toward neither cleanly. The Growth pillar rates as Weak, which is not typical of a high-growth name, while the Valuation pillar rates as Good rather than deeply discounted. It sits in a middle ground that the full UQS analysis helps clarify for Pro members.
