Energy Recovery, Inc. (Nasdaq:ERII) today announced its financial results for the first quarter ended March 31, 2021. The Company posted record-high quarterly product revenue in its core Water segment with 52% growth compared to the first quarter of 2020.

"Today, Energy Recovery is at a key inflection point as we embark on a path of sustainable, disciplined, and diversified growth. First, we must protect and grow our seawater desalination business, which is thriving as our quarterly results show," said Robert Mao, Chairman of the Board, President, and Chief Executive Officer of Energy Recovery.

Mr. Mao continued, "Second, we are expanding our pressure exchanger technology's aperture and developing pressure exchanger-based solutions for new industries. We specifically look for markets where we can reduce costs and accelerate customers' environmental sustainability. I am particularly excited by our progress developing an energy recovery device for carbon dioxide (CO₂) commercial refrigeration. The U.S. Environmental Protection Agency just this week announced an accelerated phase out of HFCs which should hasten adoption of CO₂ technology in the U.S. in the coming years. Our testing indicates that our solution excels at saving energy where today's market-leading technology fails - in warmer climates."

Mr. Mao concluded, "The coming months will be an exciting time for Energy Recovery. Significant growth in our core desalination market, combined with our strong financial position and exciting research and development ("R&D") results, gives us confidence that the future is bright."

Financial Results

Product Channel Revenue

"Our desalination business drove significant growth in the first quarter, and we continue to work towards a more diversified revenue stream for the future," said Joshua Ballard, Chief Financial Officer of Energy Recovery. "We also maintained our discipline in OPEX. General and administrative ("G&A") spend was 4% lower year-over-year, and we reduced our R&D spend over 30% while still making significant progress in our emerging technology projects. With our healthy gross margin, we can both improve profitability and invest in disciplined future growth."

Segment Reporting

To reflect Energy Recovery's evolving business, the Company realigned its segment reporting starting in the first quarter of fiscal year 2021 and recast the prior year amounts for comparability. Income and type of expense activities included in the Company's Water and Emerging Technologies segments and corporate operating expenses are as follows:

Water segment: Includes seawater desalination and industrial wastewater sales and service, SWRO and industrial wastewater R&D and sales & marketing ("S&M") efforts, other water-related R&D activities, and certain water-related S&M and G&A expenses previously reported under corporate expenses.

Emerging Technologies segment: Includes R&D efforts in continued development of the VorTeq, sales and support of the IsoBoost^® in natural gas processing which lowers the energy needed for sour gas treatment, and R&D efforts for new product development outside of desalination and industrial wastewater, and certain emerging technologies-related S&M and G&A activity expenses previously reported under corporate expenses.

Corporate operating expense: Includes certain operating expenses related to corporate activities outside of the operating segments, such as audit and accounting, some corporate legal, Board, and other separately managed general expenses not related to the identified segments.

First Quarter 2021 Business Highlights

Water Segment

• Megaproject and aftermarket channels contributed to strong sales growth while original equipment manufacturer sales remain affected by the global slowdown in tourism and hospitality.
• Product gross margin came within guidance and in-line with recent quarters, primarily due to reduction in average sales prices that began in 2020.
• We announced a joint marketing effort with DuPont Water Solutions, a global leader in purification and specialty-separation technologies, to build awareness of the benefits of pairing our Ultra PX^™ energy recovery devices with DuPont membranes in industrial wastewater treatment systems. Our focus remains on marketing and further developing our industrial wastewater customer pipeline in China and India.
• Operating expenses in this segment decreased year-over-year primarily due to lower G&A expenses, in part due to Covid-19 related slowdown in travel and lower other office expenditures. In addition R&D expenses fell year-over-year, but are expected to increase as PX development for industrial wastewater picks up.

Emerging Technologies Segment

• We completed our first live well field trials of the VorTeq^™ technology alongside Liberty Oilfield Services and one of the largest independent oil producers in the United States. The VorTeq took part in more than 25 stages on a multi-well pad in New Mexico in the first quarter. Our focus remains on extending the service life of the VorTeq cartridges, a critical hurdle for profitable commercialization.
• Investments continue in pressure exchanger-based incubation initiatives, most notably in our CO₂ commercial refrigeration efforts. Our testing indicates that our new PX can process CO₂ within the refrigeration cycle more efficiently than existing technologies and the product is undergoing design and testing in preparation for beta tests.
• Operating expenses in this segment decreased year-over-year, primarily due to reduced development expenditures related to the VorTeq, which were partially offset by a shift of R&D investment to our CO₂ activities and lower employee-related costs.

Corporate Operating Expenses

• Operating expenses increased year-over-year due primarily to higher employee-related costs largely related to higher share-based compensation expense and legal costs, partially offset by lower recruiting costs related to Energy Recovery's chief executive officer search in the first quarter of fiscal year 2020.

Bottom Line Summary

On a quarterly basis, we reported a net income of $6.9 million, or $0.12 per diluted share, for the first quarter ended March 31, 2021, compared to a net income of $0.6 million, or $0.01 per diluted share, for the first quarter ended March 31, 2020.

Cash Flow Highlights

The Company finished the first quarter ended March 31, 2021 with cash and cash equivalents of $105.4 million, and short-term investments of $14.6 million, which represents a combined total of $120.0 million.
