Energy Recovery Achieves 22% Year-on-Year Quarterly Revenue Growth, Beating Guidance

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, 2023.

Third Quarter Highlights

• Revenue of $37.0 million, exceeding the upper end of our guidance which was attributed to an increase in megaproject revenues.
• Gross margin of 69.9%, higher than our estimates due to a change in product mix coupled with an increase in sales of our PX^®.
• Operating expenses of $16.7 million, in line with prior quarters.
• Income from operations of $9.1 million.
• Net income of $9.7 million and adjusted EBITDA⁽¹⁾ of $12.0 million
• Cash and investments of $105.9 million, which include cash, cash equivalents, and short-term and long-term investments.
• Issued our annual Sustainability Report, which includes our commitment to reduce our emissions in relation to revenue by 65% by 2026. The full Sustainability Report can be found on our Sustainability page at energyrecovery.com.

David Moon, Interim Chief Executive Officer, commented on the financial results, "We delivered strong third quarter results, beating the upper end of our guidance for the quarter and we remain well-positioned to deliver on our overall Water guidance for the full year. As we look to 2024, we see growth in desalination for the 10^th consecutive year despite a challenging macroeconomic environment and project to potentially double wastewater revenue in 2024. Further, we continue to see a path to our 2026 water revenue targets."

Mr. Moon added, "In our CO₂ business, we have a number of new installations of our PX G1300 planned for the fourth quarter, have received repeat orders for additional deployments from current end-users, and are currently in advanced talks with a number of national, and multi-national, supermarket chains in Europe and the United States. We were also awarded the Refrigeration Innovation of the Year for the XTE by RAC Cooling Industry Awards, together with our partner Epta, for Epta's next-generation commercial CO₂ refrigeration system, which utilizes the PX G1300. This award provides further third-party validation of our technology. It's an exciting time to join the Energy Recovery team as the Interim President and CEO, and I look forward to working with the management team to help ensure we make substantial progress in 2024."

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 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.
