Energy Recovery Reports Record Full Year and Fourth Quarter Revenue for 2023

Energy Recovery, Inc. (NASDAQ:ERII) ("Energy Recovery" or the "Company") today announced its financial results for the fourth quarter and year ended December 31, 2023.

Fiscal Year 2023 Highlights

• Record annual revenue of $128.3 million, which includes a 79% growth in wastewater and represents nine consecutive years of revenue growth.
• Record quarterly revenue of $57.2 million, representing a 35% year-on-year growth with strong performance in Energy Recovery's primary desalination business and the continued rapid expansion of the company's wastewater sector. Water revenue was below guidance due to the delayed shipment of a single project to be shipped in 2024. This project was highlighted as a potential risk in the Q3 earnings call.
• Gross margin of 67.8%, within Energy Recovery's expectations and above guidance.
• Operating expenses of $68.0 million, in line with Energy Recovery's expectations.
• Income from operations of $19.1 million.
• Net income of $21.5 million and adjusted EBITDA⁽¹⁾ of $31.2 million.
• Operating cash flow for the year more than doubled largely due to strong customer collections and strategic efforts to optimize raw inventory turnover rates.
• Cash and investments of $122.4 million, which include cash, cash equivalents, and short-term and long-term investments.

"We achieved record annual and fourth quarter revenue in 2023, which represents our ninth consecutive year of revenue growth despite a shift of $8 million revenue associated with a single project that was pushed from the fourth quarter into 2024," commented David Moon, President and CEO.

"Our core desalination business is healthy, our wastewater business continues to grow rapidly, and we are making progress in our CO₂ refrigeration business. This year, we expect to see our newest and most efficient product, the PX Q400, achieve roughly 50% of sales in our megaproject channel. Wastewater could reach up to 10% of our Water revenue in just three years and we are pushing hard to get our PX G1300 in multiple supermarket chains in the U.S. and Europe."

Mr. Moon added, "Our focus in 2024, and beyond, is rebuilding shareholder value and trust within the market. We remain committed to our growth strategy of diversification into new markets, which is key to Energy Recovery's future. In 2024, we will continue to defend our leadership position in our core desalination business, and invest in new market opportunities in CO₂ and wastewater, while managing both expenses and cash with discipline and a focus on investing in the highest and best use of shareholder capital. I am excited by the long-term growth prospects and believe we are well-positioned to continue to grow."

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.
