Energy Recovery, Inc. (ERII): History, Ownership, Mission, How It Works & Makes Money

Energy Recovery, Inc. (ERII) is the quiet giant of water technology, but are you tracking their pivot beyond desalination, a segment that delivered a Q3 2025 gross margin of a strong 64.2%? In a world desperate for water and energy solutions, their proprietary pressure exchanger technology is critical, yet the company's full-year revenue guidance of $138 million to $145 million for core businesses shows a lumpy revenue cadence you defintely need to understand. You need to look past the Q3 2025 net income of $3.9 million and instead focus on the long-term, especially how their emerging CO2 refrigeration business-which promises validated energy savings of up to 15%-will impact their 2027 commercialization timeline. Let's break down this history, mission, and the precise mechanics of how Energy Recovery, Inc. truly makes money.

Energy Recovery, Inc. (ERII) History

You're looking for the bedrock of Energy Recovery, Inc.'s success-the history that explains their dominant position in desalination and their push into new verticals like CO2 refrigeration. The direct takeaway is that the company's trajectory is a 33-year story of relentlessly optimizing a single, core technology: the Pressure Exchanger (PX). This focus has created a high-margin, market-leading water business that now funds their expansion into other energy-intensive industries.

Given Company's Founding Timeline

Year established

Energy Recovery, Inc. was originally founded in 1992.

Original location

The company's original location was in California, though it was initially incorporated in Virginia. The current headquarters are in San Leandro, California.

Founding team members

The company was founded by Leif and Marissa Hauge. Their vision centered on developing a device that could recover wasted pressure energy, which is defintely a niche but critical problem in industrial processes.

Initial capital/funding

While the exact initial seed capital isn't public, the company secured venture capital backing in its early stages. Over a few rounds, Energy Recovery raised a total funding of approximately $5 million.

Given Company's Evolution Milestones

Given Company's Transformative Moments

The most transformative decision for Energy Recovery was the commitment to the Pressure Exchanger (PX) as a platform technology, not just a desalination component. This ceramic-based device, which transfers pressure from a high-pressure fluid to a low-pressure fluid with up to 98% efficiency, is the entire business. The company's evolution is marked by three strategic shifts:

• Dominating Desalination: The PX technology achieved a majority market share in the SWRO desalination industry, allowing the company to generate a high gross margin, often exceeding 60%. This established a reliable cash flow.
• Strategic Vertical Expansion: They diversified into wastewater treatment and CO2 refrigeration, recognizing that the core technology could solve energy recovery problems in other high-pressure industrial processes. The Emerging Technologies segment, which includes CO2, is the company's primary growth lever today.
• Funding Future Growth with Present Profits: The strong desalination business, which analysts project will drive up to $160 million in revenue for the full fiscal year 2025, is essentially funding the riskier, long-term commercialization of the CO2 business. For example, the CO2 segment alone had over 50 test installations by Q2 2025.

What this estimate hides is the slow-burn nature of the CO2 commercialization; real revenue from that segment isn't expected until 2027, but the investment is necessary now. This long-term view is critical for understanding the company's valuation. You can find more detail on their strategic outlook here: Mission Statement, Vision, & Core Values of Energy Recovery, Inc.

Energy Recovery, Inc. (ERII) How It Works

Energy Recovery, Inc. (ERII) operates by engineering and manufacturing proprietary fluid-flow technology that captures and recycles wasted pressure energy from industrial processes. Their core innovation, the PX® Pressure Exchanger® (PX), acts like a high-speed, non-electric rotary device that transfers hydraulic energy from a high-pressure waste stream to a low-pressure feed stream, dramatically cutting energy consumption.

Honestly, this technology is what makes energy-intensive processes like seawater desalination commercially viable today. The company makes money by selling these high-margin devices and complementary products, primarily to the water treatment sector, which accounts for the vast majority of its revenue.

Energy Recovery, Inc.'s Product/Service Portfolio

Energy Recovery, Inc.'s Operational Framework

The company's operations are laser-focused on manufacturing its ceramic-based PX devices and managing a lumpy revenue cycle tied to large-scale infrastructure projects. We're talking about a business where the timing of project completion dictates revenue recognition, so quarterly results can be volatile. For example, management reiterated its full-year guidance for 2025, projecting revenue on the high end of $160 million, but expects roughly 55% of that to come in the fourth quarter.

Here's the quick math: The Desalination segment is the breadwinner, driving around 60% of total revenue. The company's strong gross margin of 64.2% in Q3 2025 shows the profitability of its core technology. But, to be fair, the company is actively controlling operating expenses, which were $16.9 million in Q3 2025, and is cutting R&D spending in emerging technologies to protect profitability while the CO2 market rollout takes longer than defintely hoped.

• Manufacture core PX devices using highly engineered alumina ceramic.
• Focus on large, multi-year desalination contracts; a single November 2025 order in Saudi Arabia totaled nearly $33 million.
• Maintain a strong liquidity position with $79.9 million in cash and investments as of Q3 2025.
• Prioritize the high-margin Water segment to fund investment in the slower-growing Wastewater and CO2 verticals.
