Energy Recovery Affirms FY 2023 Guidance, Continues Investments in Wastewater and CO2 Business Growth

Energy Recovery, Inc. (NASDAQ:ERII) ("Energy Recovery" or the "Company") today announced its financial results for the second quarter and six months ended June 30, 2023.

Second Quarter Highlights

• Revenue of $20.7 million, within the lower end of guidance. Revenue was lower due to a timing delay of a $5.7 million megaproject shipment that will subsequently be recognized in the third quarter.
• Gross margin of 65.4%, within the upper range of our guidance of 64% – 66% for the quarter for Water.
• Operating expenses of $16.1 million, which included growing investments in sales and marketing, and research and development to support business expansion.
• Loss from operations of $2.6 million primarily attributable to lower revenue and gross margin due to timing of revenue recognition of a megaproject shipment.
• Net loss of $1.7 million and adjusted EBITDA⁽¹⁾ of $0.2 million.
• Cash and investments of $97.5 million which include cash, cash equivalents, and short-term and long-term investments.
• Expanded the PX U Series product line used in and tailored for ultra high-pressure reverse osmosis applications.

Robert Mao, Chairman, President and CEO, commented on the financial results, "We delivered second quarter results in line with our previous guidance and we expect our outlook for the remainder of the year to be unchanged. As of today, our desalination and wastewater businesses are on track, and the significant increases in megaproject shipments expected in the second half of 2023, give us confidence in our ability to achieve our full-year revenue guidance."

Mr. Mao added, "We continue to achieve new milestones in our CO₂ business. We were awarded the prestigious Refrigeration Innovation of the Year Award by ATMO for our PX G1300^™ in June. We are also partnering with a major U.S. refrigeration manufacturer on a new training center in California that will incorporate our PX G1300, providing us a unique opportunity to educate the market further on our device. We continue to deploy the PX G1300 at new locations in Europe with our partners Fieuw Koeltechniiek nv and Epta S.p.A., and in North America. We are focused on building and enhancing relationships within the industry, as well as expanding our team in both the U.S. and Europe."

Use of Non-GAAP Financial Measures

This press release includes certain non-GAAP financial measures, including adjusted operating margin, adjusted net income (loss), adjusted net income (loss) per share, adjusted effective tax rate, 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.
