Energy Recovery stock trades steady as margin gains follow strong 2024 revenue growth

Energy Recovery stock reflects a mix of steady trading and improving fundamentals, after the company grew 2024 revenue and earnings and entered 2025 with rising margins and expanding orders across desalination and industrial water technologies.

Energy Recovery stock, tied to Energy Recovery Inc. (ISIN US2927641074) on the Nasdaq market, sits against a backdrop of solid recent fundamental progress, including double digit revenue growth and greater profitability in 2024 and early 2025. As of 30 June 2025, the company reported higher full year revenue and earnings compared with 2023 according to its investor information, underlining that Energy Recovery has been able to translate its desalination and industrial water technology portfolio into stronger financial results. For investors, the key theme in the latest reports is that margins and cash generation improved along with top line expansion, which together help underpin current valuations.

Revenue up compared with 2023

According to Energy Recovery's own investor materials for 2024, the company generated higher revenue for the year compared with 2023, reflecting both growth in its core desalination devices and contributions from newer industrial applications. The reported revenue increase was quantified as a double digit percentage gain versus the prior year, showing that Energy Recovery was able to grow significantly faster than low single digit global GDP and industrial output in the same period. In practical terms, the shift from 2023 to 2024 meant Energy Recovery booked tens of millions of dollars in additional sales, turning a previously more mixed growth picture into a consolidated uptrend.

Energy Recovery also reported that its gross margin in 2024 improved compared with 2023, rising by several percentage points as a result of better pricing, product mix and operational efficiency, according to the figures published in its investor relations context. Where earlier years had seen gross margin move within a relatively narrow band, the 2024 numbers marked a wider spread between revenue and cost of goods sold, meaning that the company retained more profit per dollar of sales. This margin expansion is particularly relevant for Energy Recovery stock because higher gross margin gives more room for operating investments while still supporting net income growth.

Operating income and net earnings improve

In addition to revenue and gross margin, Energy Recovery's 2024 report showed an increase in operating income relative to 2023. Based on the company's published data, operating income grew by a double digit percentage from the prior year, strengthening the overall profitability profile. The improvement reflects both the expansion of the top line and disciplined spending on research, development, and administrative costs. For shareholders, this shift means the company is not only selling more equipment and solutions but also doing so with better cost control, which tends to support higher valuations for Energy Recovery stock over time.

Net income for 2024 followed the same positive trajectory. Energy Recovery reported that net income rose compared with 2023, with earnings per share increasing accordingly. The EPS gain between 2023 and 2024 was described in the company's investor information as a material improvement, marking another year in which earnings grew faster than revenue. This pattern indicates that operating leverage is starting to show through the income statement: once fixed costs are covered, incremental revenue drops disproportionately to the bottom line, which is a favorable dynamic for an equipment and technology provider focused on desalination and industrial water treatment.

Order patterns and backlog stability

Beyond the headline revenue and earnings figures, Energy Recovery's investor updates for late 2024 and early 2025 pointed to a reasonably stable order environment. The company highlighted that orders for seawater reverse osmosis desalination projects remained robust in 2024, with a mix of new plant builds and retrofit work contributing to sales of pressure exchanger devices and related equipment. While exact order intake numbers by quarter were not detailed publicly in summarizing materials, Energy Recovery indicated that its backlog of contracted work extended over multiple quarters, giving visibility into future revenue streams.

In the industrial and wastewater segments, Energy Recovery noted that pilot installations and first commercial deployments of its newer technologies contributed initially modest but growing revenue in 2024. The company described a progression in which small contributions from industrial flows in 2022 and 2023 became more meaningful by 2024, helping diversify the business away from pure desalination. This directional shift matters for Energy Recovery stock because a more balanced revenue mix can reduce dependence on desalination capital expenditure cycles, potentially smoothing earnings over time.

Cash position and investment capacity

Energy Recovery's cash and short term investment position at the end of 2024, as presented in its investor relations resources, showed a solid balance sheet with no large net debt burden. The company reported cash and equivalents sufficient to fund ongoing research and development, plant investments and working capital needs without requiring immediate external equity or debt financing. This financial flexibility allows Energy Recovery to continue pursuing new product development in industrial water treatment and energy efficiency technologies while still considering shareholder returns through potential future dividends or buybacks if board and regulatory conditions permit.

Free cash flow in 2024, derived from operating cash flow minus capital expenditures, was positive according to Energy Recovery's disclosures, and higher than in 2023. The improvement reflected both stronger profitability and careful capital spending. For investors, positive and rising free cash flow is a critical metric because it underpins the ability to self fund growth and, over the longer term, to return capital. While Energy Recovery has historically focused on reinvestment in its technology and market presence, the progression in free cash flow adds an additional layer of optionality for capital allocation.

Desalination pressure exchanger portfolio

Energy Recovery's desalination business is anchored by its pressure exchanger devices, which are used in seawater reverse osmosis plants to recover hydraulic energy and significantly lower electricity consumption. These devices are designed to allow operators to reduce the energy cost of producing fresh water by recapturing energy from high pressure concentrate streams and transferring it to incoming feed water with minimal losses. By improving the efficiency of desalination plants, Energy Recovery's technology contributes directly to lower operating costs and reduced environmental impact associated with energy use.

According to information available through the company's technical and product descriptions, Energy Recovery's desalination portfolio has seen adoption across a wide range of plant sizes, from smaller municipal installations to some of the world's largest seawater desalination facilities. The cumulative capacity of plants equipped with the company's pressure exchanger technology has grown over time, making Energy Recovery a key player in the global desalination equipment market. For investors, the scale of installed base matters because it supports recurring replacement and service revenue in addition to new project sales.

Industrial applications expand addressable market

In recent years, Energy Recovery has focused on extending its core energy recovery and pressure exchanger technology into industrial and wastewater applications, including processes in the chemical, food and beverage, and oil and gas sectors. The company has introduced tailored products for these markets, such as devices designed to handle different fluid compositions and operating pressures while still delivering meaningful energy savings. Early industrial deployments have demonstrated that the same energy recovery principles used in desalination can be applied to other pressurized liquid systems, creating a broader addressable market.

Energy Recovery's strategy in industrial segments has emphasized pilot projects and collaborative demonstrations with key customers, with the aim of building a track record that can support larger scale adoption. Over 2023 and 2024, the company reported progress in converting pilot installations into repeat orders, which contributed to the incremental growth in industrial revenue described in its investor communications. From an Energy Recovery stock perspective, successful industrial expansion is important because it can reduce cyclicality tied to desalination plant investment, and may carry higher margin if Energy Recovery can position its solutions as differentiated energy efficiency enablers.
