Product Revenue Growth of 26% for Fiscal Year 2020
$50 million Share Buyback Program Announced
SAN LEANDRO, Calif. - March 11, 2021 - Energy Recovery, Inc. (Nasdaq: ERII) today announced its financial results for the fourth quarter and fiscal year ended December 31, 2020. The Company achieved 26% product revenue growth for the fiscal year 2020 across all business segments, which includes a 27% year-over-year growth in our core seawater desalination business.
Strong 2020 results combined with projected growth in 2021 and 2022 will likely increase Energy Recovery’s cash balances. As a result, the Board of Directors of the Company approved a share repurchase program on March 9, 2021. Under this program, the Company may repurchase up to $50.0 million of the Company’s outstanding common stock. The repurchases will take place in open-market transactions and will focus on maximizing the number of shares purchased by Energy Recovery.
“We ended a difficult 2020 stronger than we started,” said Bob Mao, Chairman of the Board, President and Chief Executive Officer of Energy Recovery. “We kept our employees safe while keeping our production running, grew our base water business and achieved record revenue despite the pandemic, launched our new Ultra PX™ energy recovery device for industrial wastewater treatment, and issued our first Environmental, Social and Governance (“ESG”) report.”
Mr. Mao continued, “I believe 2021 is going to be an even more exciting year for Energy Recovery. In early March, we deployed the VorTeq at a live well with one of the largest independent oil producers in the U.S., a key step towards demonstrating the value proposition of the product and ensuring readiness for commercial deployment. We continue to work on the other critical hurdle for profitable commercialization - extending the service life of the VorTeq cartridges.”
Mr. Mao concluded, “We also continue to push the boundaries of our core technology, the pressure exchanger, to handle new operating environments and industrial applications, including actively developing capabilities to handle gases. With this broader operating range, our first target is to address the challenges faced in industrial and commercial refrigeration. We are taking a disciplined approach to incubating new products, with clear financial and time bounds on each of our initiatives, which we believe will enable us to more rapidly drive shareholder value.”

“We beat our 2020 water guidance by more than 1%, a growth target that we first communicated in October 2019 and later reaffirmed once we understood the impact of the COVID-19 pandemic,” said Joshua Ballard, Chief Financial Officer of Energy Recovery. “In addition, we achieved our product gross margin target in 2020, and operating expenditures grew only 6% compared to a guidance of 10-12% in 2019, despite a $2.3 million one-time impairment charge. More importantly, in-line with our third quarter comments, VorTeq-related research and development (“R&D) spend fell 17% for the year, and 45% year-on-year in the fourth quarter. These OPEX results underscore our commitment to disciplined R&D, as well our ability to leverage our existing operations as we grow while increasing profitability. You can expect this disciplined approach to OPEX and new product introduction in 2021.”
Fiscal Year 2020
Revenues
For the year ended December 31, 2020, our total revenue increased 37% as compared to prior year driven by two primary factors: 27% growth in our core water desalination business, and a 91% increase in our oil & gas license development revenue due to the accelerated recognition of revenue associated with the termination of the Schlumberger exclusivity agreement.
For the 5th consecutive year, our Water segment achieved record revenue for the year ended December 31, 2020, with the megaproject (“MPD”) channel as the main driver of our revenue growth. In 2020, large scale desalination projects were generally unaffected by COVID-19 and the decline in economic conditions. Strong growth in our MPD channel is indicative of the growing demand for potable water globally, as well as the technological conversion occurring within the industry as thermal desalination plants begin to be decommissioned and replaced with reverse osmosis plants.
Our original equipment manufacturer (“OEM”) and aftermarket (“AM”) channels, which contain projects of shorter duration, were negatively affected by COVID-19 and the resulting decline in the economic conditions in fiscal year 2020, which ultimately delayed certain new installation and upgrade projects, as well as non-critical plant maintenance. Specifically, in our OEM channel, we sell into a number of industries, including tourism and hospitality, which were greatly affected by COVID-19.
In our Oil & Gas segment we accelerated revenue recognition from the termination of the license agreement between us and Schlumberger in the second quarter of 2020. No revenue was recognized in the second half of 2020, and there will be no future license revenue recognized associated with this contract.
Product Gross Margin
For the year ended December 31, 2020 product gross margin decreased 280 basis points as compared to prior year. This decrease was primarily a result of costs associated with reduced utilization of our manufacturing facilities due to COVID-19, increased costs related to COVID-19 safety protocols, and overhead costs of our Tracy, California facility. The increasing size and volume of MPD customer projects has also exerted downward pressure on our average per unit selling price, which contributed to product gross margin reductions.
Operating Expenses
For the year ended December 31, 2020, operating expenses increased $3.2 million as compared to prior year. Excluding the $2.3 million impairment expense of certain long-lived assets that were directly related to the termination of the VorTeq License Agreement, the increase in operating expense was due primarily to growth in general and administrative (“G&A”) expenses. The increase in our G&A expenses is largely due to increased investment to protect our employees from COVID-19, full year effect of hires that occurred in 2019, increased facility costs, and professional fees related to our ESG efforts.
Sales and marketing (“S&M”) expenses decreased as compared to prior year due primarily to COVID-19, as we temporarily reduced a majority of travel-related marketing events.
Research and development (“R&D”) expenses were relatively flat as compared to prior year. Expenditures related to the development of the VorTeq peaked in the first half of 2020, but fell 17% for the fiscal year as compared to prior year. This decrease in spending was partially offset by costs to support other incubation initiatives.
Bottom Line Summary
On an annual basis, we reported a net income of $26.4 million, or $0.47 per diluted share, for the year ended December 31, 2020, compared to a net income of $10.9 million, or $0.19 per diluted share, for the year ended December 31, 2019.
Fourth Quarter 2020
Revenues
For the fourth quarter ended December 31, 2020, total revenue increased 36% compared to the fourth quarter ended December 31, 2019. This increase was due primarily to 67% growth in product revenue in the Water segment, as compared to the fourth quarter ended December 31, 2019. In the Oil & Gas segment, there was no license and development revenue recognized as a result of the termination of the VorTeq License Agreement.
The Water desalination business growth in the fourth quarter ended December 31, 2020 was driven by strong performance of our MPD channel. We continued to observe COVID-19 related slowdowns in our OEM and AM channels as industries such as tourism and hospitality deferred reverse osmosis projects. In our AM channel, some customers sought to delay non-critical maintenance.
Product Gross Margin
For the fourth quarter ended December 31, 2020, product gross margin decreased 250 basis points as compared to the fourth quarter ended December 31, 2019. The decrease in product gross margin was primarily related to lower average selling price of our PX as the growing magnitude of MPD projects exerted downward pressure on per unit pricing.
Operating Expenses
For the fourth quarter ended December 31, 2020 operating expenses decreased $1.5 million as compared to the fourth quarter ended December 31, 2019. This decrease was due primarily to lower R&D expenditures, driven by a 45% decrease in VorTeq-related testing activities, and partially offset by our continued investment in our incubation initiatives.
G&A expenses increased as compared to the fourth quarter ended December 31, 2019, due primarily to higher personnel and facility-related costs and partially offset by lower travel and professional services expenditures.
S&M expenses decreased as compared to the fourth quarter ended December 31, 2019, due primarily to COVID-19 related slowdowns in marketing and travel related activities.
Bottom Line Summary
On a quarterly basis, we reported a net income of $3.5 million, or $0.06 per diluted share, for the fourth quarter ended December 31, 2020, compared to a net deficit of $0.6 million, or ($0.01) per diluted share, for the fourth quarter ended December 31, 2019.
Cash Flow Highlights
We finished the year ended December 31, 2020 with cash and cash equivalents of $94.3 million, and short-term investments of $20.4 million, which represents a combined total of $114.7 million. Despite the COVID-19 pandemic, our customer collections, and therefore cash flows, remain strong, indicative of the overall strength of the desalination market in 2020.
