Energy Recovery Reports its Third Quarter 2024 Financial Results

SAN LEANDRO, Calif. - October 30, 2024 – Energy Recovery, Inc. (Nasdaq:ERII) (“Energy Recovery” or the “Company”) today announced its financial results for the third quarter and nine months ended September 30, 2024.

Third Quarter Highlights
Revenue of $38.6 million, reaching the upper end of our guidance of $35 - $39 million.
Gross margin of 65.1%, a decrease of 480 bps, as compared to Q3’2023, due primarily to higher manufacturing costs and higher costs related to product mix.
Operating expenses of $18.1 million, an increase of 7.8%, as compared to Q3’2023, due primarily to higher consulting costs related to enhancement of our corporate growth strategy and higher employee costs.
Income from operations of $7.1 million, a decrease of 22.7%, as compared to Q3’2023, mainly due to higher operating expenses and lower gross margin.
Net income of $8.5 million and adjusted EBITDA(1) of $11.6 million.
Cash and investments of $139.9 million, which include cash, cash equivalents, and short- and long-term investments.


David Moon, President and CEO, commented on the financial results, “We delivered strong third quarter results, hitting the upper end of our guidance for the quarter and, although there is still work to be done, we believe we are well-positioned in this quarter to deliver on our guidance for the full year. Our core desalination business continues to demonstrate durability of growth, our wastewater business continues to expand, and we are making real progress this year in our CO2 refrigeration business.”

Mr. Moon continued, “With our PX G1300 summer data collection complete, we just issued a white paper with the measurement and verification results, provided by a third party engineering firm, that we believe will be an important next step to getting the PX G1300 integrated into OEM systems designs and ultimately specified by supermarkets. Finally, we concluded our strategic work on what I have termed our Playbook. This Playbook outlines our five-year plan to grow all three of Energy Recovery’s businesses. It is an ambitious and I believe achievable blueprint for growth that I, along with Mike Mancini, CFO, and our business unit leads, are excited to lay out next month on a live investor webinar we are hosting on November 18, 2024.”

Forward-Looking Statements
Certain matters discussed in this press release and on the conference call are “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including the belief that the Company is well-positioned in the fourth quarter to deliver on our guidance for the full year, the belief that the Company is making real progress this year in its CO2 refrigeration business, the belief that the Company’s recently published white paper is an important next step to getting the PX G1300 integrated into original equipment manufacturers’ systems designs and ultimately specified by supermarkets, and the belief that the Company’s Playbook is an achievable blueprint for growth. These forward-looking statements are based on information currently available to the Company and on management’s beliefs, assumptions, estimates, or projections and are not guarantees of future events or results. Potential risks and uncertainties include risks relating to the future demand for the Company’s products, risks relating to performance by our customers and third-party partners, risks relating to the timing of revenue, and any other factors that may have been discussed herein regarding the risks and uncertainties of the Company’s business, and the risks discussed under “Risk Factors” in the Company’s Form 10-K filed with the U.S. Securities and Exchange Commission (“SEC”) for the year ended December 31, 2023, as well as other reports filed by the Company with the SEC from time to time.

All forward-looking statements are made as of today, and the Company assumes no obligation to update such statements.




Use of Non-GAAP Financial Measures
This press release includes certain non-GAAP financial measures, including adjusted operating margin, adjusted net income, adjusted net income per share, adjusted EBITDA and free cash flow. Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position, or cash flows that either exclude or include amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles in the United States of America, or GAAP. These non-GAAP financial measures do not reflect a comprehensive system of accounting, differ from GAAP measures with the same captions, and may differ from non-GAAP financial measures with the same or similar captions that are used by other companies. As such, these non-GAAP measures should be considered as a supplement to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. The Company uses these non-GAAP financial measures to analyze its operating performance and future prospects, develop internal budgets and financial goals, and to facilitate period-to-period comparisons. The Company believes these non-GAAP financial measures reflect an additional way of viewing aspects of its operations that, when viewed with its GAAP results, provide a more complete understanding of factors and trends affecting its business.

Notes to the Financial Results
Adjusted operating margin is a non-GAAP financial measure that the Company defines as income (loss) from operations which excludes i) share-based compensation; and ii) executive transition costs, such as executive search costs, retention costs, one-time severance costs and one-time corporate growth strategy costs, divided by revenues.
Adjusted net income is a non-GAAP financial measure that the Company defines as net income which excludes i) share-based compensation; ii) executive transition costs; and iii) the applicable tax effect of the excluded items including the share-based compensation discrete tax item.
Adjusted net income per share is a non-GAAP financial measure that the Company defines as net income (loss), which excludes i) share-based compensation; ii) executive transition costs and iii) the applicable tax effect of the excluded items including the share-based compensation discrete tax item, divided by basic shares outstanding.
Adjusted EBITDA is a non-GAAP financial measure that the Company defines as net income (loss) which excludes i) depreciation and amortization; ii) share-based compensation; iii) executive transition costs; iv) other income, net, such as interest income and other non-operating income (expense), net; and v) provision for (benefit from) income taxes.
Free cash flow is a non-GAAP financial measure that the Company defines as net cash provided by (used in) operating activities less capital expenditures.
